Stoke Bruerne is a small village near towcestor off of the A5 in between Birmingham and London on the Grand Union Canal

There was various land owners before 1805, one of them was the ‘Saxon lord' swain son of Azor, son of lefs, Lord of Stoke, he in 1086 herd 21 houses with families of ‘villains and borders' the total value of the houses was 10 shillings a year. After swain the ‘Saxon lord' died with no heirs a Norman Noble took the land , it then passed from one family to another, it acquired the name Bruerne from sir William de Bruerne, who was a friend of both king Richard the ‘lion heart' and his brother King John. De Bruerne help the manor of stoke and also sitlehanger (shutlanger) and Aldrintone (Alderton) from William de Warenn Earl of Surrey, He was also a substantial Landowner. At the beginning of the 13th century Sir William was given the manor of Stoke Bruerne, and in 1217 he appointed the first Rector of Stoke Bruerne, named Richard de Rolf. In Stoke Bruerne the population increased from 609 people in 1801 to 823 people in 1971. Pre 1805 Stoke Bruerne was a small simple Hamlet, it had a figure of either setting, it had a church surrounded by thatched cottages, and then there was the farms in separate areas. Most of the people who lived there were farmhands and had very low wages, they also did not have much if any knowledge of other villages/towns, they also rented there houses from landowners like the Hesketh's and the Duke of Grafton, they had poor diets and eat very little meat, they eat any food that was being harvested at the time. They had a low protein die, and no access to medical care a tall so thee was high infantry mortality (baby's dieing before be fore 12 months of age) there was no dentist and low life expectancy, some people with a large enough garden would of kept chickens and maybe a pig, and would have also grown there own vegetables. The canal was built for many reasons, one of which was because of transport problems, they had some roads, but they were mostly dirt tracks, there was problems such as rain, snow and mud stopping this, also there were highwaymen who could rob you, and turn pikes slowed down traffic at nights, but stoke Bruerne was close to the A5 which was later improved by Thomas Telford. Then there was the idea of transporting good's by the sea, but there was problems such as seasonal problems like ice and driving rain, there also was all year gales, it also was quite expensive as boats sank, and there was piracy. There was another idea of using the rivers, but thee also was problems with this such as flooding and drought, tidal problems, going upstream was difficult, there was also inland piracy, and not all areas have rivers deep enough and wide enough to take a boat. The speed of the transport was varied, the horse and cart could go around 5 MPH, and so could the river boat, sea ships speeds varied on the wind speed and the direction, but the canal had the most direct route unlike the horse and cart. From London to Birmingham it was roughly 100 miles, which if you went at 5 MPH non-stop in the quickest route would take 20 hours, but the roads were not the most direct route so it would take longer, and also you needed to stop to give the horses breaks and to sleep, also non of the transport routes apart from the A5 which was built at a later date were direct. Construction of the tunnel began in 1793 and with over 3,000 men working on it covering nearly 100 miles between Brentford and Braunston, but they had poor roads and lack of instantaneous communication, this made organization very hard and put a great strain on the building of the canal, by the end of 1796 the canal had reached Blisworth from Braunston, with the 2042 yard tunnel at the Braunston summit and high embankment at Weedon and Bugbrooke then work was plannedon the long tunnel planed by jessop and bearnes to pierce the ridge on the southern side of stoke Bruerne. The preliminary work of the Blisworth tunnel started in 1703 but cutting stopped in January of 1796, local word says the tunnel collapsed but there's no factual proof of this, jessop want to go for all locks which would of in tolled 29 in all, with a short summit with reservoir's, Barnes proposed a new tunnel on a different line, he was supported with Robert Whitworth and John Barnes, the company agreed on principle but could not sanction work until 1802. After huge economic pressure the company had to act quickly, so they build a toll road over the hill in 1797, it had good benefit but was unable too meet the demands of the trade company's, so then Benjamin Outram was called in too make a tramway over the hill, it was a double track road 4 ft wide. The locks had been completed and the ancillary works, the canal now awaited the opening of the tunnel, heading from both ends met on 25th of February 1805 and final work was completed on 19th of March, the official opening was on Monday 25th of March 1805, the tunnel had in fact cost à ¯Ã‚ ¿Ã‚ ½90,003 2s 4d. At 3,075 yards 2 feet, nearly à ¯Ã‚ ¿Ã‚ ½30 per yard. We see in the 1844 map how Stoke Bruerne was cut in two by the new canal and how the village street had been re routed from its ancient line along what is now chapel land to the green by the school, to now going alone its present course over the new canal bridge over the top lock. There was some buildings that changed at the opening of the canal, but some that did not change were buildings like the Church and the Rectory house, and all the cottages near the church there was also new buildings at the opening of the canal like the mill house and more pubs, also the pubs main entrance changed from the town side to the canal side. While the canal was in its ‘Golden Years' stocks went up by more then ten times in forty years, in 1801 the stocks were doubled, by 1810 then stocks had then gone up by 6 times, then by 1821stocks had raised to up too 9 times more then there first value, and then they had got raised by even more, by 1831they had gone up by 13 times, this for stoke brokers was a huge profit and brought great riches to the town and a lot more jobs, the population also had a huge raise. In 1805 the canal opened, in 1815 the Napoleonic wars were ending, in 1835 the double bridge was built for the big canal to enable traffic to get through easier, in 1838 the London to Birmingham railway was completed, and from there on the canal was failing in profits, economically the village got stronger and more social because of more people were living there and there was a higher demand for goods as many many canal boats passed through daily with there own separate needs, also the new jobs that were available were now better paid because they required a higher level of skill and they were usually very dangerous. Also there was better quality food as there was a higher demand, the food was now usually fresher, also there was a lot more meat which helped to balance there diet, and there was more dairy products, so the health of the community improved and so did the life expectancy, and infant mortality lowered. Houses also improved, houses were now cleaner, mainly because soap was now carried through Stoke Bruerne, houses were also improved with slate and bricks now that they traveled through Stoke Bruerne, houses were also warmer because coal prices lowered and people became richer to buy the coal with, some houses now also started having glass in there windows, and there was now also a ‘school pence tax' which paid for the first school in Stoke Bruerne. There was not many complaints about the canal because either they could not write a formal complain or they did not have any power to put there word forward, but one person who did complain was the Rector, he complained because his garden was cut in half, he managed to get a bridge put up so that he could go collect his fish for Fridays dinner from his pond on the other side. Many people could of complained though, because we can presume that many farmers lost all of there workers, the villagers would have been annoyed about the badly behaved navies, there would have been a lot of noise because of the building of the canal, mud in the village, and dust in the summer, there would also of been a lot of horse muck because of the canal, and also there would have been great dangers of people falling in, also villagers were not rich enough to buy shares so they would of not gained from the canal as the same ways as the land owners did, but ordinary villagers did not complain because local landowners wanted the canal and the villagers were too afraid they would lose there homes to complain. When the railway was built it hugely impacted the canal and the village of Stoke Bruerne, the canal lost shares drastically from when it was planned to up to 20 years later, it also lost much of its customers, who could now not only send there goods on the train at a faster and cheaper way, but they could also could travel with there goods to ensure there safe transport and if they fancied going to visit someone or on a business trip. In 1835 the construction of the Railway started, but also at this time they made a double lock canal to help with traffic and also to encourage more canal users, in 1838 the railway opened, the London to Birmingham Line. The Railway was built as it was a lot quicker then the canal, or any other forms of transport and that it went in a straight line near the canal, the trains traveled at speeds of around 40 MPH, and they also could carry a lot more goods then the canal, a canal carried one canal boats worth, which was not much, a train could have lots more carriages, it could carry as many carriages as it had the power to., a canal boat is about 72 feet by 7 feet, having the railway led to cheaper goods because the transport was cheaper so everyone(apart from the canal transporters) were gaining, either by cheaper transport or cheaper prices, also trains rarely suffered from seasonal problems like ice roads and flooding. Also it was cheaper too build the railway as the track was set by the canal and already surveyed, and also the canal could transport the equipment they needed like shale timber and sleepers, railways took paying passengers also which helped more money come in, also they had stations with waiting centers and loo's, towns like Birmingham grew and got bigger because they were on the main line of the Railway, but Northampton was not on the main line so it did not grow. Some social effects were the unemployment for canal workers in the village, but some of them would have gone to the railways, especially the engineers who were greatly needed on the railways, also the navies would have gone to the railways. Railways were less labor intense so there was less jobs available for it, but people could now commute to towcestor and other big towns and cites, which meant they now would all commute to there job and turn into a commuting village. In the 20th century Stoke Bruerne got a lot more popular, it had a larger tourism attraction to it because of its turn from a small village, to a village with a major canal running through it which brought a lot more customers wishing to either stay at there Inn's, eat there or just to have a break, also there was many facilities there with equipment that boatmen needed to make it through there journey, there was spare boards among other things, but all this tourism let to high traffic problems and a lot of noise for the locals who were not best pleased, there was not much parking space so some local farmers open there fields for people to park in at a higher then average price. In summer there was a lot of litter, from the many tourists that visited Stoke Bruerne, also the pubs and shops and restaurants had higher then average prices because there was no competition between anyone else because they were very far from any other places, and sometimes Stoke Bruerne was over crowded which made it an unpleasant place to visit sometimes. Also there was more noise because of children and there was dangers by the canal side, EG the towpath which they could of fell into if they were not careful, there was also more jobs gained by tourism, but they were seasonal and low paid, also now house prices have gone up in Stoke Bruerne because Milton Keynes and Towcestor were close by, and now nearly all the villagers are commuters. There was new transport routes made as the M1 opened in the early 1960's, and the Beaching Acts shut down the railways in the 1960's also which helped the canal slightly. In this section I am going to discuss the sources I used to help me complete my coursework. Extracts, by David Blagrove was written in 1991 and it is a secondary source although he would have used primary information in his research. I could say that he is bias as he is a canal enthusiast, I can prove this by saying that he does not deal with other modes of transport that were competition with for the canal in the midlands at the time e.g. Horse and cart on the A5 would have been the canals main competition. I am able to use other sources to prove Blagrove's Evidence e.g. the 1844 map shows the rector's land split in two. The second written source is by Whittaker written in 1879, although this is a secondary source it is the earliest written source available to me and he also used primary evidence, it was the only source that contained population figures but its downside is it is a re-write and having not seen the original I am unable to find out weather or not valuable information has been lost. The Last Written source I wish to discuss is written by Lawrence Wood in 1975. It is a secondary source but Wood would of have had access to primary information such as marriage, death and birth certificates and information from parish records, the biggest problem with this source is that it does not even mention the canal and really it is produced for visitors/tourist's to the church. The two maps I used were dated 1844 and 1920. The 1844 map shows the layout of the canal side in Stoke Bruerne when the canal was at its busiest showing building bridges and locks. The 1920 map shows that the barge marina had been filled in, proving the canal's decline as mentioned by Blagrove. Therefore I have been able to prove that the canal's construction through the village of Stoke Bruerne changed the village socially, peoples job's changed, physically, the centre of the village was no longer the church and financially, I can assume that living conditions and health improved and the canal company's made large profits.

Second Foundation 2. Two Men without the Mule

The ship was in near-readiness. Nothing lacked, but the destination. The Mule had suggested a return to Trantor – the world that was the bulk of an incomparable Galactic metropolis of the hugest Empire mankind had ever known – the dead world that had been capital of all the stars. Pritcher disapproved. It was an old path – sucked dry. He found Bail Channis in the ship's navigation room. The young man's curly hair was just sufficiently disheveled to allow a single curl to droop over the forehead – as if it had been carefully placed there – and even teeth showed in a smile that matched it. Vaguely, the stiff officer felt himself harden against the other. Channis' excitement was evident, â€Å"Pritcher, it's too far a coincidence.† The general said coldly: â€Å"I'm not aware of the subject of conversation.† â€Å"Oh- Well, then drag up a chair, old man, and let's get into it. I've been going over your notes. I find them excellent.† â€Å"How†¦ pleasant that you do.† â€Å"But I'm wondering if you've come to the conclusions I have. Have you ever tried analyzing the problem deductively? I mean, it's all very well to comb the stars at random, and to have done all you did in five expeditions is quite a bit of star-hopping. That's obvious. But have you calculated how long it would take to go through every known world at this rate?† â€Å"Yes. Several times,† Pritcher felt no urge to meet the young man halfway, but there was the importance of filching the other's mind – the other's uncontrolled, and hence, unpredictable, mind. â€Å"Well, then, suppose we're analytical about it and try to decide just what we're looking for?† â€Å"The Second Foundation,† said Pritcher, grimly. â€Å"A Foundation of psychologists,† corrected Channis, â€Å"who are as weak in physical science as the First Foundation was weak in psychology. Well, you're from the First Foundation, which I'm not. The implications are probably obvious to you. We must find a world which rules by virtue of mental skills, and yet which is very backwards scientifically.† â€Å"Is that necessarily so?† questioned Pritcher, quietly. â€Å"Our own ‘Union of Worlds' isn't backwards scientifically, even though our ruler owes his strength to his mental powers.† â€Å"Because he has the skills of the First Foundation to draw upon,† came the slightly impatient answer, â€Å"and that is the only such reservoir of knowledge in the Galaxy. The Second Foundation must live among the dry crumbs of the broken Galactic Empire. There are no pickings there.† â€Å"So then you postulate mental power sufficient to establish their rule over a group of worlds and physical helplessness as well?† â€Å"Comparative physical helplessness. Against the decadent neighboring areas, they are competent to defend themselves. Against the resurgent forces of the Mule, with his background of a mature atomic economy, they cannot stand. Else, why is their location so well-hidden, both at the start by the founder, Hari Seldon, and now by themselves. Your own First Foundation made no secret of its existence and did not have it made for them, when they were an undefended single city on a lonely planet three hundred years ago.† The smooth lines of Pritcher's dark face twitched sardonically. ‘And now that you've finished your deep analysis, would you like a list of all the kingdoms, republics, planet states and dictatorships of one sort or another in that political wilderness out there that correspond to your description and to several factors besides?† â€Å"All this has been considered then?† Channis lost none of his brashness. â€Å"You won't find it here, naturally, but we have a completely worked out guide to the political units of the Opposing Periphery. Really, did you suppose the Mule would work entirely hit-and-miss?† â€Å"Well, then† and the young man's voice rose in a burst of energy, â€Å"what of the Oligarchy of Tazenda?† Pritcher touched his ear thoughtfully, â€Å"Tazenda? Oh, I think I know it. They're not in the Periphery, are they? It seems to me they're fully a third of the way towards the center of the Galaxy.† â€Å"Yes. What of that?† â€Å"The records we have place the Second Foundation at the other end of the Galaxy. Space knows it's the only thing we have to go on. Why talk of Tazenda anyway? Its angular deviation from the First Foundation radian is only about one hundred ten to one hundred twenty degrees anyway. Nowhere near one hundred eighty.† â€Å"There's another point in the records. The Second Foundation was established at ‘Star's End.'† â€Å"No such region in the Galaxy has ever been located.† â€Å"Because it was a local name, suppressed later for greater secrecy. Or maybe one invented for the purpose by Seldon and his group. Yet there's some relationship between ‘Star's End' and ‘Tazenda,' don't you think?† â€Å"A vague similarity in sound? Insufficient.† ‘Have you ever been there?† â€Å"No.† â€Å"Yet it is mentioned in your records.† â€Å"Where? Oh, yes, but that was merely to take on food and water. There was certainly nothing remarkable about the world.† â€Å"Did you land at the ruling planet? The center of government?† â€Å"I couldn't possibly say.† Channis brooded about it under the other's cold gaze. Then, â€Å"Would you look at the Lens with me for a moment?† â€Å"Certainly.† The Lens was perhaps the newest feature of the interstellar cruisers of the day. Actually, it was a complicated calculating machine which could throw on a screen a reproduction of the night sky as seen from any given point of the Galaxy. Channis adjusted the co-ordinate points and the wall lights of the pilot room were extinguished. In the dim red light at the control board of the Lens, Channis' face glowed ruddily. Pritcher sat in the pilot seat, long legs crossed, face lost in the gloom. Slowly, as the induction period passed, the points of light brightened on the screen. And then they were thick and bright with the generously populated star-groupings of the Galaxy's center. â€Å"This,† explained Channis, â€Å"is the winter night-sky as seen from Trantor. That is the important point that, as far as I know, has been neglected so far in your search. All intelligent orientation must start from Trantor as zero point. Trantor was the capital of the Galactic Empire. Even more so scientifically and culturally, than politically. And, therefore, the significance of any descriptive name should stem, nine times out of ten, from a Trantorian orientation. You'll remember in this connection that, although Seldon was from Helicon, towards the Periphery, his group worked on Trantor itself.† â€Å"What is it you're trying to show me?† Pritcher's level voice plunged icily into the gathering enthusiasm of the other. â€Å"The map will explain it. Do you see the dark nebula?† The shadow of his arm fell upon the screen, which took on the bespanglement of the Galaxy. The pointing finger ended on a tiny patch of black that seemed a hole in the speckled fabric of light. â€Å"The stellagraphical records call it Pelot's Nebula. Watch it. I'm going to expand the image.† Pritcher had watched the phenomenon of Lens Image expansion before but he still caught his breath. It was like being at the visiplate of a spaceship storming through a horribly crowded Galaxy without entering hyperspace. The stars diverged towards them from a common center, flared outwards and tumbled off the edge of the screen. Single points became double, then globular. Hazy patches dissolved into myriad points. And always that illusion of motion. Channis spoke through it all, â€Å"You'll notice that we are moving along the direct line from Trantor to Pelot's Nebula, so that in effect we are still looking at a stellar orientation equivalent to that of Trantor. There is probably a slight error because of the gravitic deviation of light that I haven't the math to calculate for, but I'm sure it can't be significant.† The darkness was spreading over the screen. As the rate of magnification slowed, the stars slipped off the four ends of the screen in a regretful leave-taking. At the rims of the growing nebula, the brilliant universe of stars shone abruptly in token for that light which was merely hidden behind the swirling unradiating atom fragments of sodium and calcium that filled cubic parsecs of space. And Channis pointed again, â€Å"This has been called ‘The Mouth' by the inhabitants of that region of space. And that is significant because it is only from the Trantorian orientation that it looks like a mouth.† What he indicated was a rift in the body of the Nebula, shaped like a ragged, grinning mouth in profile, outlined by the glazing glory of the starlight with which it was filled. â€Å"Follow ‘The Mouth.' † said Channis. â€Å"Follow ‘The Mouth' towards the gullet as it narrows down to a thin, splintering line of light. Again the screen expanded a trifle, until the Nebula stretched away from â€Å"The Mouth† to block off all the screen but that narrow trickle and Channis' finger silently followed it down, to where it straggled to a halt, and then, as his finger continued moving onward, to a spot where one single star sparked lonesomely; and there his finger halted, for beyond that was blackness, unrelieved. â€Å"‘Star's End,'† said the young man, simply. â€Å"The fabric of the Nebula is thin there and the light of that one star finds its way through in just that one direction – to shine on Trantor.† â€Å"You're tying to tell me that-† the voice of the Mule's general died in suspicion. â€Å"I'm not trying. That is Tazenda – Star's End.† The lights went on. The Lens flicked off. Pritcher reached Channis in three long strides, â€Å"What made you think of this?† And Channis leaned back in his chair with a queerly puzzled expression on his face. â€Å"It was accidental. I'd like to take intellectual credit for this, but it was only accidental. In any case, however it happens, it fits. According to our references, Tazenda is an oligarchy. It rules twenty-seven inhabited planets. It is not advanced scientifically. And most of all, it is an obscure world that has adhered to a strict neutrality in the local politics of that stellar region, and is not expansionist. I think we ought to see it.† â€Å"Have you informed the Mule of this?† â€Å"No. Nor shall we. We're in space now, about to make the first hop.† Pritcher, in sudden horror, sprang to the visiplate. Cold space met his eyes when he adjusted it. He gazed fixedly at the view, then turned. Automatically, his hand reached for the hard, comfortable curve of the butt of his blaster. â€Å"By whose order?† â€Å"By my order, general†- it was the first time Channis had ever used the other's title -â€Å"while I was engaging you here. You probably felt no acceleration, because it came at the moment I was expanding the field of the Lens and you undoubtedly imagined it to be an illusion of the apparent star motion.† â€Å"Why? Just what are you doing? What was the point of your nonsense about Tazenda, then?† â€Å"That was no nonsense. I was completely serious. We're going there. We left today because we were scheduled to leave three days from now. General, you don't believe there is a Second Foundation, and I do. You are merely following the Mule's orders without faith; I recognize a serious danger. The Second Foundation has now had five years to prepare. How they've prepared, I don't know, but what if they have agents on Kalgan. If I carry about in my mind the knowledge of the whereabouts of the Second Foundation, they may discover that. My life might be no longer safe, and I have a great affection for my life. Even on a thin and remote possibility such as that, I would rather play safe. So no one knows of Tazenda but you, and you found out only after we were out in space. And even so, there is the question of the crew.† Channis was smiling again, ironically, in obviously complete control of the situation. Pritcher's hand fell away from his blaster, and for a moment a vague discomfort pierced him. What kept him from action? What deadened him? There was a time when he was a rebellious and unpromoted captain of the First Foundation's commercial empire, when it would have been himself rather than Channis who would have taken prompt and daring action such as that. Was the Mule right? Was his controlled mind so concerned with obedience as to lose initiative? He felt a thickening despondency drive him down into a strange lassitude. He said, â€Å"Well done! However, you will consult me in the future before making decisions of this nature.† The flickering signal caught his attention. â€Å"That's the engine room,† said Channis, casually. â€Å"They warmed up on five minutes' notice and I asked them to let me know if there was any trouble. Want to hold the fort?† Pritcher nodded mutely, and cogitated in the sudden loneliness on the evils of approaching fifty. The visiplate was sparsely starred. The main body of the Galaxy misted one end. What if he were free of the Mule's influence- But he recoiled in horror at the thought. *** Chief Engineer Huxlani looked sharply at the young, ununiformed man who carried himself with the assurance of a Fleet officer and seemed to be in a position of authority. Huxlani, as a regular Fleet man from the days his chin had dripped milk, generally confused authority with specific insignia. But the Mule had appointed this man, and the Mule was, of course, the last word. The only word for that matter. Not even subconsciously did he question that. Emotional control went deep. He handed Channis the little oval object without a word. Channis hefted it, and smiled engagingly. â€Å"You're a Foundation man, aren't you, chief?† â€Å"Yes, sir. I served in the Foundation Fleet eighteen years before the First Citizen took over.† â€Å"Foundation training in engineering?† â€Å"Qualified Technician, First Class – Central School on Anacreon.† â€Å"Good enough. And you found this on the communication circuit, where I asked you to look?† â€Å"Yes, Sir.† â€Å"Does it belong there?† â€Å"No, Sir.† â€Å"Then what is it?† â€Å"A hypertracer, sir.† â€Å"That's not enough. I'm not a Foundation man. What is it?† â€Å"It's a device to allow the ship to be traced through hyperspace.† â€Å"In other words we can be followed anywhere.† â€Å"Yes, Sir.† â€Å"All right. It's a recent invention, isn't it? It was developed by one of the Research Institutes set up by the First Citizen, wasn't it?† â€Å"I believe so, Sir.† â€Å"And its workings are a government secret. Right?† â€Å"I, believe so, Sir.† â€Å"Yet here it is. Intriguing.† Channis tossed the hypertracer methodically from hand to hand for a few seconds. Then, sharply, he held it out, â€Å"Take it, then, and put it back exactly where you found it and exactly how you found it. Understand? And then forget this incident. Entirely!† The chief choked down his near-automatic salute, turned sharply and left. The ship bounded through the Galaxy, its path a wide-spaced dotted line through the stars. The dots, referred to, were the scant stretches of ten to sixty light-seconds spent in normal space and between them stretched the hundred-and-up light-year gaps that represented the â€Å"hops† through hyperspace. Bail Channis sat at the control panel of the Lens and felt again the involuntary surge of near-worship at the contemplation of it. He was not a Foundation man and the interplay of forces at the twist of a knob or the breaking of a contact was not second nature to him. Not that the Lens ought quite to bore even a Foundation man. Within its unbelievably compact body were enough electronic circuits to pin-point accurately a hundred million separate stars in exact relationship to each other. And as if that were not a feat in itself, it was further capable of translating any given portion of the Galactic Field along any of the three spatial axes or to rotate any portion of the Field about a center. It was because of that, that the Lens had performed a near-revolution in interstellar travel. In the younger days of interstellar travel, the calculation of each â€Å"hop† through hyperspace meant any amount of work from a day to a week – and the larger portion of such work was the more or less precise calculation of â€Å"Ship's Position† on the Galactic scale of reference. Essentially that meant the accurate observation of at least three widely-spaced stars, the position of which, with reference to the arbitrary Galactic triple-zero, were known. And it is the word â€Å"known,† that is the catch. To any who know the star field well from one certain reference point, stars are as individual as people. Jump ten parsecs, however, and not even your own sun is recognizable. It may not even be visible. The answer was, of course, spectroscopic analysis. For centuries, the main object of interstellar engineering was the analysis of the â€Å"light signature† of more and more stars in greater and greater detail. With this, and the growing precision of the â€Å"hop† itself, standard routes of travel through the Galaxy were adopted and interstellar travel became less of an art and more of a science. And yet, even under the Foundation with improved calculating machines and a new method of mechanically scanning the star field for a known â€Å"light signature,† it sometimes took days to locate three stars and then calculate position in regions not previously familiar to the pilot. It was the Lens that changed all that. For one thing it required only a single known star. For another, even a space tyro such as Channis could operate it. The nearest sizable star at the moment was Vincetori, according to â€Å"hop† calculations, and on the visiplate now, a bright star was centered. Channis hoped that it was Vincetori. The field screen of the Lens was thrown directly next that of the visiplate and with careful fingers, Channis punched out the co-ordinates of Vincetori. He closed a relay, and the star field sprang to bright view. In it, too, a bright star was centered, but otherwise there seemed no relationship. He adjusted the Lens along the Z-Axis and expanded the Field to where the photometer showed both centered stars to be of equal brightness. Channis looked for a second star, sizably bright, on the visiplate and found one on the field screen to correspond. Slowly, he rotated the screen to similar angular deflection. He twisted his mouth and rejected the result with a grimace. Again he rotated and another bright star was brought into position, and a third. And then he grinned. That did it. Perhaps a specialist with trained relationship perception might have clicked first try, but he'd settle for three. That was the adjustment. In the final step, the two fields overlapped and merged into a sea of not-quite-rightness. Most of the stars were close doubles. But the fine adjustment did not take long. The double stars melted together, one field remained, and the â€Å"Ship's Position† could now be read directly off the dials. The entire procedure had taken less than half an hour. Channis found Han Pritcher in his private quarters. The general was quite apparently preparing for bed. He looked up. â€Å"News?† â€Å"Not particularly. We'll be at Tazenda in another hop.† â€Å"I know.† â€Å"I don't want to bother you if you're turning in, but have you looked through the film we picked up in Cil?† Han Pritcher cast a disparaging look at the article in question, where it lay in its black case upon his low bookshelf, â€Å"Yes.† â€Å"And what do you think?† â€Å"I think that if there was ever any science to History, it has been quite lost in this region of the Galaxy.† Channis grinned broadly, â€Å"I know what you mean. Rather barren, isn't it?† â€Å"Not if you enjoy personal chronicles of rulers. Probably unreachable, I should say, in both directions. Where history concerns mainly personalities, the drawings become either black or white according to the interests of the writer. I find it all remarkably useless.† â€Å"But there is talk about Tazenda. That's the point I tried to make when I gave you the film. It's the only one I could find that even mentioned them.† â€Å"All right. They have good rulers and bad. They've conquered a few planets, won some battles, lost a few. There is nothing distinctive about them. I don't think much of your theory, Channis.† â€Å"But you've missed a few points. Didn't you notice that they never formed coalitions? They always remained completely outside the politics of this corner of the star swarm. As you say, they conquered a few planets, but then they stopped – and that without any startling defeat of consequence. It's just as if they spread out enough to protect themselves, but not enough to attract attention.† â€Å"Very well,† came the unemotional response. â€Å"I have no objection to landing. At the worst – a little lost time.† â€Å"Oh, no. At the worst – complete defeat. If it is the Second Foundation. Remember it would be a world of space-knows-how-many Mules.† â€Å"What do you plan to do?† â€Å"Land on some minor subject planet. Find out as much as we can about Tazenda first, then improvise from that.† â€Å"All right. No objection. If you don't mind now, I would like the light out.† Channis left with a wave of his hand. And in the darkness of a tiny room in an island of driving metal lost in the vastness of space, General Han Pritcher remained awake, following the thoughts that led him through such fantastic reaches. If everything he had so painfully decided were true – and how all the facts were beginning to fit – then Tazenda was the Second Foundation. There was no way out. But how? How? Could it be Tazenda? An ordinary world? One without distinction? A slum lost amid the wreckage of an Empire? A splinter among the fragments? He remembered, as from a distance, the Mule's shriveled face and his thin voice as he used to speak of the old Foundation psychologist, Ebling Mis, the one man who had – maybe – learned the secret of the Second Foundation. Pritcher recalled the tension of the Mule's words: â€Å"It was as if astonishment had overwhelmed Mis. It was as though something about the Second Foundation had surpassed all his expectations, had driven in a direction completely different from what he might have assumed. If I could only have read his thoughts rather than his emotions. Yet the emotions were plain – and above everything else was this vast surprise.† Surprise was the keynote. Something supremely astonishing! And now came this boy, this grinning youngster, glibly joyful about Tazenda and its undistinguished subnormality. And he had to be right. He had to. Otherwise, nothing made sense. Pritcher's last conscious thought had a touch of grimness. That hypertracer along the Etheric tube was still there. He had checked it one hour back, with Channis well out of the way. Second Interlude It was a casual meeting in the anteroom of the Council Chamber – just a few moments before passing into the Chamber to take up the business of the day – and the few thoughts flashed back and forth quickly. â€Å"So the Mule is on his way.† â€Å"That's what I hear, too. Risky! Mighty risky!† â€Å"Not if affairs adhere to the functions set up.† â€Å"The Mule is not an ordinary man – and it is difficult to manipulate his chosen instruments without detection by him. The controlled minds are difficult to touch. They say he's caught on to a few cases.† â€Å"Yes, I don't see how that can be avoided.† â€Å"Uncontrolled minds are easier. But so few are in positions of authority under him-â€Å" They entered the Chamber. Others of the Second Foundation followed them.

The challenges nurses are facing with nursing informatics Essay

The challenges nurses are facing with nursing informatics - Essay Example According to Ball (303), Informatics thus refers to the process of modification of a discipline by combining information as well as knowledge to its discipline. In fact, it is an acknowledged specialty for nurses who are registered, but it poses several challenges to the profession of nursing. Nurses have experienced other problems as a result of the innovations in means of communication, improved transport systems as well as the created global economies. This has compelled the nurse to accept the universal perception of health policies, which has led to the changing roles of the nurses, as they have had to incorporate the global phenomena into the primary health care system.The use of technology has been the greatest challenge that the nurses have had to face. They have had to use computers in health caregiving, administration duties as well as in education and research (Ericksen, 1). Basically, informatics is incorporated in every task of a nurse. All these challenges facing the nu rsing profession are caused by advancements in technology, reforms in the healthcare sector, too much workload and little number of professional nurses as well as the increased lifespan of the patients.This is because research has shown that the number of healthcare providers has always been less than that of the health seekers. Technology, therefore, becomes the only solution to this growing burden. Nurses must be kept abreast with the all the advances in technology to enhance the quality as well as the price of care given to patients.

Research proposal for female and management positions Essay

Research proposal for female and management positions - Essay Example About 30% of women in government positions are in decision making positions. Even though the women’s enrolment in institutions of higher learning is on the increase, the same has not been replicated in their participation in economic matters (McCrohan & Preiss, 2006). Their participation in economic affairs has increased by less than 7% since the year 1985 as compared to their enrolment in tertiary institutions, which has grown by more than 40% since the 1970’s. Worldwide studies have additionally revealed that women participation within the UAE in economic activities is extremely low when compared to their counterparts in other participating countries. This is in reference to businesses that are starting and established business activities. In contrast, the men in the UAE are over twenty times more involved in young businesses that are starting up (Erogul & McCrohan, 2007). Literature Review Previous literature within the country contains limited research on the women leaders found in the UAE just like outside researches, which also do not have much on them. The research previously has done on women focuses on women leaders in the US economy. However, there is little comparison with other women managers around the globe. Therefore, there is  a great need for carrying out research on the distinctive roles that women play in the economy. This will be done so as to enable conceptualization and validation of their unique roles. Some little research can however be found concerning the factors which support the leaders among women in their professions. They include parental supports especially their fathers, socialization within their families along with spousal support (Moore, 2007). Most of the previous research focuses on the support they get from their families. Little information can be found on the conditions at their places of work that facilitate the advancements in their careers. The previous research also dwells on the challenges that women encounter in advancing their leadership in business. The experiences of women leaders in the region have been documented based on their Islamic faiths. In contrast, women in countries such as France and Denmark with children aged go to work. This is enabled by the availability of pre-primary child care that is offered in schools (The Times, 1990). The current research shows there is a need to facilitate the conceptualization and qualitative validation of the differences among women and their separate experiences. The UAE is on record as being the best within the region in terms of treating her women. In addition, present research indicates that 10% of the managerial posts in the world of Arabs are usually held by their women. The changing of the traditional perceptions of a woman’s place is a slow process within the UAE (Erogul & McCrohan, 2007). Research Question †¢ Does insufficient self confidence, family conflicts, long working and stereotyping among women within th e UAE affect the participation in leadership positions in businesses? Theoretical Framework The dependent variable in the research is the participation of women in leadership positions in business within the UAE. It will be explained by the following independent variables: insufficient self confidence, family conflicts, long working hours and stereotyping. Women usually lack confidence because of their place within the society as stipulated by Islam. Their lack of self confidence is also attributable to the family conflicts that occur in their lives. Women within the region are often

Music Therapy for Pain Management Essay Example | Topics and Well Written Essays - 2250 words

Music Therapy for Pain Management - Essay Example While practitioners report good results with it, most of the practice is based on empiric evidence. Therefore, it would be worthwhile to explore research to find out evidence that can support current practice or can change practice. To determine evidence, a literature search was undertaken on the available database with the key words "music", "therapy", "music therapy", "nursing practice", "pain management", "complementary therapy", "alternative therapy", and "palliative nursing." This resulted into 234 articles. These articles were further searched on key words "research articles." This narrowed down the number of articles to 34. Among these articles, a search was conducted with the key word "national guideline," and this revealed 0 articles. This indicated there exists no nursing practice guidelines on pain management with music therapy. Further search was conducted with the phrase "systemic review", and this resulted into 6 articles. One of these articles was chosen, and another 5 articles were chosen from the previous group. The inference from this search was that music therapy is practiced in contemporary palliative care nursing practice, but there is no national guideline for its use. However, the existence of many systemic reviews tells us about the evidence that can be used in practice. Article that Best Supports Nursing Interventions The article that best supports nursing interventions is "Music as an Intervention in Hospitals" by Evans (2001) on behalf of The Joanna Briggs Institute for Evidenced based Nursing and Midwifery. This is a systemic review of articles graded on the basis of level of evidence. The author sites evidence from literature that music has been used for all age groups in a wide variety of clinical care settings as adjuncts to conventional management. The care settings include intensive care, coronary care units, and even outpatient departments. From the evidence, it appears that it has been used universally across practice settings. In some cases, it has also been used a relaxation technique. The author presents findings from different articles and studies. Evidence suggests that music in the form of recorded music from a compact disc player was the therapeutic music of choice. The randomized controlled trials indicate that music has been used for reduction of anxiety, relaxation, reduction o f pain, improvement of cognitive function, buffering noise, increasing satisfaction, improvement of mood, increment of exercise tolerance, and improvement of tolerance of some procedures. Music has also been used to alleviate symptoms of anxiety and pain. The outcome measures for pain control were decrease in the severity of pain and decreased requirement of analgesics. For procedures, the decreased requirement of sedatives was evidenced by improvement in patient satisfaction, better tolerance of procedure, and notable elevation of mood. The researchers recorded symptomatic reduction of anxiety and corroborated these through physical examination, which indicated reduction in heart rate and respiratory rate. No subjective reduction of pain symptoms was noted, although the dose of analgesics required to produce a desired pain relief was less. Similarly, reduction of required dose of sedatives during unpleasant procedures was noted. This review did not find any evidence that music impr oved tolerance of the procedures, but it improved mood of the

Outcomes in Proffessional Nursing Assignment Example | Topics and Well Written Essays - 500 words

Outcomes in Proffessional Nursing - Assignment Example However, several global governance and policy issues control the quality and effectiveness of healthcare services in global perspective. Kruk (2010) in the article highlights the entrance of private institutions and multi-stakeholders in the healthcare industry. On the one hand, it has resulted in greater funding and equity availability in global healthcare governance, it has also created gaps in the traditional centralized and currently demanded non-centralized decision making environment at healthcare desk. Latest and complex technologies have facilitated the scope of healthcare service but also rippled the cross-national health markets as focus shifts from local to global health. Increased global disparities among nations gave rise to Millennium Development Goals (MDGs) in which 189 countries became signatories. With this, eradication of poverty, gender inequality, diseases and supporting countries with vulnerable health systems became the tenets of better health performance. In this regard, the role of entities involved namely private institutions, nurses, government and issues surrounding their functioning like their composition, degree of control and autonomy, training and development and geographical and cultural factors; has been highlighted by Kabene et al. (2006). Healthcare services are marked by professionalism, dedication and expert service and as claimed by the authors, human resources management in this regard should enjoy a strategic position with considerable amount of decision making freedom, decentralized working environment and multifaceted professionals with understanding of finance, marketing and other domains which could help them nurture a culture supporting global health agenda. In the light of above findings, it becomes crystal clear that responsibility and accountability is going to rise in professional nursing practice. Apart from normal care, nurses are now entrusted with

The sustainability of Organizing Essay Example | Topics and Well Written Essays - 500 words

The sustainability of Organizing - Essay Example It is this trust that helps an organization to be fruitful and develop. By using the word 'trust' it is not meant to be applicable to any specific firm or individual. It is not only applicable towards clients and suppliers but it is relevant to everybody associated with the company or organization. This principle could be formulated into a HR technique that would yield surplus in the long run. Trust is not just about the stake holders of the company but more so it is applicable towards its employees too. There is no meaning of showing a bright future where there is none; rather it would be far more positive attitude to reveal everything that is true about the organization. It is not only a moral approach but a trust building operation that would prove to be helpful in future and a HR manager would never let go a chance to win the faith of a worker. (Mukherjee, 28) Revealing the open truth about the company is the most effective way of taking an employee into complete confidence. If the statement 'man is a social animal' is true then this management principal would be the best possible relevant example of it. Consider this- every individual is shaped by the virtue of his or her environment (Lamb, 23). Therefore it is obvious that an employee would be governed by the nature of workplace he or she is associated with.

Strategic Management in the Non Profit Sector Essay - 1

Strategic Management in the Non Profit Sector - Essay Example Partnerships are an important function in the non-profit sector. The positioning of efforts in tandem with that of another organisation helps the organisation move towards effective goal achievement. This also promotes harmony in activities and the society in general. The structuring and strategic management of goals and structures within an organisation must lead to partnerships with external parties. This is due to the fact that a not for profit organisation basically deals with what is outside, rather than what is inside. Its activities revolve around the betterment of people and their environments. For this reason, it is important to work in tandem with other organisations that can provide it with something that is lacking within the organisation in question. This is a matter of strategic positioning and the strategic use and management of resources that belong to the society as a whole. Partnerships are also a good option in strategic management for new and developing organisati ons as it helps in the sharing of costs and resources. It also helps the new organisation in garnering the requisite amount of experience and leverage in the market.

Quality vs. Quantity in the Nursing Profession Essay

Quality vs. Quantity in the Nursing Profession - Essay Example For almost 200 years, nursing has been a profession with high standards of ethical service. It is not surprising how people looked up to the profession with respect and awe. The profession is not just about wearing the ever-identified white cap over one's heads and playing second fiddle to the physician. The scope of the nursing profession has made it easier to identify possible problems that may pose as a hindrance to its development in the near future. Current issues plaguing the profession are not allowed to taint what the past has meticulously built and endowed. The new generation nurses are then tasked to make sure the profession continue being regarded with esteem despite global problems. There have been accusations that the current nursing education does not produce enough competent nurses. Recent commercialization in the educational system owes to inconvenience this profession. Current diploma programs and associate nursing programs are offered as a shorter track to allow the resource pools to stretch faster. It is a common knowledge though, that the mastery of skills in the real world takes more time to adjust to the demands of practical full time nursing. Theoretical preparation however equips a practitioner the full understanding and applications of learning applicable to the actual practice. Education does play a central role into the nurses' profession but practice makes a better nurse. To address the issue of fast-track education which promotes incompetence, the different states have identified entry levels into the practice of professional nursing. The State of Texas and other states have identified licensed nursing practice along a continuum from the licensed vocational nurse to the doctorate prepared registered nurses. Vocational nurses are required to pass the National Council Licensure Examination for Practical Nurses (NCLEX-PN). Granted with a 90-day temporary permit, examinees are required to practice with direct supervision before allowance of a licensed practice. Baccalaureate degree holders, considered as articulate in the broader Nursing perspective are also required to take the NCLEX-RN and a 60-day temporary period while waiting testing and licensure. Other states have their own various rules and advisories however dwell on the same premise as the State of Texas and the rest. Considering that major employers for nurses are hospital- based institutions, the face of the nursing education is being monitored by the government to undergo face-lifts in their educational programs. Despite the widespread difficulties encountered, professional nursing practice is prevailed upon by the actual educational preparation of a nurse and her exposure to the technical nursing skills. The United Kingdom, recognizing the same potential for the same kind of grievance has addressed the issue in a different manner. Ensuring high standards of care in hospitals, routine inspections by the Commission for Health Improvement and Patient Environment Action Team is tasked to oversee the matter. According to Health Minister John Denham, "over 400 nurse consultants will be posted with new top clinical grade for nurses and midwives". Sarah Mullaly, the Chief Nursing Officer added that "the majority of nursing care delivered in the country

Student Values Essay Example for Free

Student Values Essay Encarta defines Values as the accepted principles or standards of an individual or a group. The University of Phoenix has clearly defined these standards for each student in the student handbook. As a student at the University of Phoenix, there are many values that I find extremely important. I have narrowed it down to three for discussion in this paper: Promoting the University of Phoenixs Mission Statement; Consistent Attendance; and Participation in Learning Teams. According to the University Of Phoenix, its mission is to educate working adults to develop the knowledge and skills that will enable them to achieve their professional goals, improve the productivity of their organizations, and provide leadership and service to their communities (University Of Phoenix, 2005, p. 2). To fulfill this mission, the University of Phoenix states it will: Facilitate cognitive and affective student learning, develop competence in the communication, critical thinking, collaboration, and information utilization; provide instruction that bridges the gap between theory and practice; to use technology to create effective modes and means of instruction; improve the teaching/learning system, curriculum, instruction, learning resources, counseling and student services by assessing student learning; foster a spirit of innovation that focuses on providing academic quality, service, excellence, and convenience to the working adult; and to generate the financial resources necessary to support the Universitys mission (University Of Phoenix, 2005, p. 2). To paraphrase from the handbook, our responsibilities as students states that we act ethically with one another (students, faculty, University staff); welcome the contributions of not only students, but faculty and staff members in creating an atmosphere of respect and recognition; foster a productive learning atmosphere; constructively accepting and providing feedback; identify individual and professional values of ourselves and others; show independence and direction in the conclusion of group/individual learning objectives; Be accountable for our actions (communication, interactions); recognize that conflicts/resolutions between individuals/groups are necessary to the team learning process; preserve confidentiality and privacy of personal or professional information being communicated; accountability for group achievements from working collaboratively in the learning process; adhere to the University principles on plagiarism/academic cheating; observe all laws and adhere to the University policies. In order to support the Universitys mission, we, as students, must follow certain values during our studies at the University of Phoenix. Without these values, we would not be able to uphold the Universitys mission. Personally, I uphold the mission statement by participating to the fullest degree possible, putting forth my best efforts as a student, and maintaining a high degree of ethical standards. I also find regular class attendance an important value, as a University of Phoenix Student. Whether it is traditional, online or direct study, class attendance is mandatory and essential for effective learning. Since we are online students, class participation is extremely important. Dr. Wilson states that Participation is very important online. You will be expected to participate four days a week in several different discussions and to contribute at least two substantive discussion messages on each of those four days (Wilson, 2006, p7). Because our class is based on the Active Learning Model, our classroom is a dynamic learning arena. As stated in the University Catalog, the model is based first on the assumption that the learners active involvement in the learning process is essential to good practice. Thus, University of Phoenix classrooms are intended to be dynamic learning spaces (University Of Phoenix, 2005, p. 13). For this reason, it is imperative that classes not be missed or we would not be able to participate in the active learning environment. Another value that is conducive to learning is the development of the Learning Team. A Learning Team is a small group of students, ranging from three to six people (from different parts of the country or world) that is crucial to our learning environment. Learning Teams are an essential design element in the Universitys teaching and learning model through which students develop the ability to collaborate ? an ability expected of employees in information-age organizations and one of the Universitys primary learning goals (University Of Phoenix, 2005, p. 14). The Learning Team forces us to work effectively and efficiently. The team must work together in order to complete the assigned tasks. Working in groups also teaches us how to work in diverse groups in the real-world. In conclusion, the values I have listed only scratch the surface of the value system. Values are a part of us and society as a whole. They may relate to how each of us views the world around us or may be the basis for the laws that govern us. Without values, we could be living in a world that would not be able to distinguish between what is right and what is wrong. References University of Phoenix (2005).

Design a simple apnea detection system

Design a simple apnea detection system CHAPTER 1 1.1 INTRODUCTION AIM The aim of the project is to design a simple apnea detecting system with an alarm and to classify the type of apnea identified using LabVIEW. 1.1.1 Normal Respiratory Event: Respiration is the phenomenon of supplying oxygen to the tissues and removing the carbon dioxide from the tissues. External respiration is the process of exchange of gases between the lungs and atmosphere. Internal respiration is the process of gas exchange in the tissues. The balance between the absorption and excretion of these gases in blood are maintained as breathing activity. During inspiration the level of blood in oxygen increases and it decreases during exhalation. Chemoreceptors are the sensory receptors in the blood stream that senses the level of oxygen and carbon dioxide in blood ,and sends signals to the brain. Then the brain allows the opening of larynx and vocal cords, followed by the expansion of ribcage and diaphragm muscles. The chest cavity enlarges to allow the inflow of oxygen into the lungs thus resulting in inhalation process. Similarly the chest cavity occludes during the process of exhalation and expels the carbon dioxide from lungs. More of oxygen inflow re sults in maximum tidal volume and a normal respiratory flow. Fig 1.1 shows the normal respiratory signal with respiration rate of 12 breaths per minute. 1.1.2 Applications Sleep analysis Polygraphy Pulmonary function Stress test Sports Sudden Infant Death Syndrome (SIDS) 1.1.3 Respiration Signal Specifications Amplitude 2-200mV Frequency waveform-0 150Hz Repetition frequency- 20 cycles per minute (adults) 100 cycles per minute (neonates) 1.1.4 Respiratory Measurements Respiration rate Tidal volume Apneas Obstructive apnea Central apnea Hypopnea Tachypnea Bradypnea Apnea index Also several correlations between EEG, REM sleep, apneas, quiet sleep, non-quiet sleep and de-saturations. 1.2 APNEA AND ITS TYPES Apnea is the cessation of breathing during sleep which may precede the arrest of the heart and circulation in several clinical situations such as head injury, drug overdose, anesthetic complications and obstructive respiratory diseases. Apnea may also occur in premature babies during the first weeks of life because of their immature nervous system. If apnea persists for a prolonged period, brain function can be severely damaged. Therefore, patients suffering from apnea require close and constant observation of their respiratory activity. Apnea monitors are particularly useful for monitoring the respiratory activity of premature infants. There are three types of sleep apnea. They are Obstructive apnea Central sleep apnea Mixed or complex sleep apnea 1.2.1 Obstructive Sleep Apnea Individuals with obesity due to low muscle tone and soft tissue around the airway give rise to a narrowed airway ,so they are at high risk of obstructive sleep apnea. The elderly people are more likely to suffer from OSA than young people because of their food habits, smoking and alcoholic life style. Men are more typical sleep apnea sufferers when compared to women and children.The risk of OSA rises with increasing body weight, age, high cholesterol, sinus problems, and in addition, patients with diabetes have up to three times the risk of having OSA compared to others. Loudsnoring, restless sleep, and sleepiness during the daytime are some of the common symptoms of OSA. Diagnostic tests include homeoximetryorpolysomnographyin a sleep clinic. Treatment includes CPAP apparatus that gives continuous positive airway pressure in order to expand their narrowed nasal pathway 1.2.2 Central Sleep Apnea When the brains respiratory control centers are imbalanced during sleep, it results in pure central sleep apnea ,also called as Cheyne-Stokes respiration. In this type of apnea the brain pauses to trigger the respiratory activity for about 30 seconds and triggers when it realizes that the patient suffocates for oxygen. The sleeper do not breathe for a certain period, during which there are no chest movements and no effort by the patient. Brain does not react immediately with a neurological feedback to make the respiratory rate even. There is a swing between apnea and hyperpnea in order to compensate the need for oxygen. After an apnea episode the hypoxia condition is reduced by breathing faster and absorbing more oxygen. Central sleep apnea may be due to hypertension, excess stress,and neuronal damage.In most of the cases CSA is treated with medications while some need surgery. Fig.1.3 shows Central Sleep Apnea. 1.2.3 Mixed Sleep Apnea Mixed sleep apnea is a combination of obstructive and central sleep apnea . It is also called as complex sleep apnea.When obstructive sleep apnea syndrome is severe and longstanding, some episodes of central apnea develop during the course of sleep. Though the exact mechanism of the loss of central respiratory drive during sleep in OSA is unknown it is most commonly related to acid-base and CO2feedback malfunctions originating fromheart failure. Complex sleep apnea has been described by researchers as a different dimension of sleep apnea. Patients with complex sleep apnea when treated with positive airway pressure for OSA was observed to exhibit persistent central sleep apnea. In sleep-disordered breathing there is a collection of diseases and symptoms relating to body mass, cardiovascular, respiratory, and occasionally, neurological dysfunction that have a synergistic effect. 1.2.4 Hypopnea Hypopnea refers to a transient reduction of airflow (often while asleep) that lasts for at least 10 seconds, shallow breathing, or an abnormally low respiratory rate. Breathing that is shallower or slower than normal. Hypopnea is distinct from apnea in which there is no breathing. Hypopnea comes from the Greek roots hypo- (meaning low, under, beneath, down, below normal) and pnoe (meaning breathing). Hypopnea is less severe than apnea (which is a more complete loss of airflow). It may likewise result in a decreased amount of air movement into the lungs and can cause oxygen levels in the blood to drop. It more commonly is due to partial obstruction of the upper airway 1.2.5 Tachypnea Tachypnea means elevated respiratory rate. In some situations, this might be usual, for example when climbing a flight of stairs. In disease it is indicative of problems with oxygenation. It occurs when the patient is breathing really hard to compensate for the higher than usual PCO2. When the patient is tachypneic it is important to sit him up in bed. In tachypnea the tidal volume is decreased, the minute volume may be the same because the respiratory rate is increased. Decreased tidal volume will have bad consequences for the patient because a lot of energy is being spent on moving dead air space which does not help oxygenate the interior of lungs where gas exchange takes place. 1.2.6 Bradypnea This is a slow respiratory rate which is seen in the post anesthetic or sedated patient. Bradypnea is also seen in patients who have taken overdoses of barbiturates and/or hypnotics. Bradypnea with a respiratory rate of more than ten breaths may correct itself as the patient recovers from the anaesthetic gases. Sometimes, in bradypnea, the patient compensates by increasing the tidal volume thereby the blood gases and oxygen saturation remain stable.Fig 1.6 shows bradypnea with respiratory rate 8b/min. 1.3 IMPEDANCE PNEUMOGRAPHY Impedance pneumography is another practical method to monitor the breathing of the patient. The technique also enables the simultaneous monitoring of the heart rate and respiration. This has certain inherent disadvantages. One is that the placement of the electrodes is very critical and other is cardiovascular artifact. This results from the detection of movement between the electrodes because of the cardiovascular system, rather than due to respiration. Apnea monitors need to be designed to reject this artifact. The principle of impedance pneumography is to pass a current through the chest between two electrodes, and from the resultant voltage to determine the changes in chest impedance which occur during respiration. It has been proposed that the impedance change occurring in respiration is directly proportional to the change in volume of air contained in the thorax, and therefore reflects tidal volume. The technique works by applying a current of approximately 10 microamperes to 1milliamperes with a frequency of 30-100 kHz to the thorax. This frequency is high enough to avoid stimulation of tissues, electrode polarization and excessively high skin impedance. The electrodes are always maintained with negligible potential difference which makes it possible to measure the impedance of a central core of thoracic tissue.Thus these impedance changes are obtained as thoracic changes that gives details about respiration.Fig 1.7 shows the block diagram Of impedance pneumography technique. 1.4 LABVIEW AND ITS APPLICATIONS LabVIEW Laboratory Virtual Instrumentation Engineering Workbench.LabVIEW is a graphical programming environment used by millions of engineers and scientists to develop sophisticated measurement, test, and control systems using intuitive graphical icons and wires that resemble a flowchart. Biomedical Application: Multisim Simulation with anECGAmplifier Noninvasive Blood Pressure (NIBP) Analyzer Analog ECGGenerator Heart Rate Variability (HRV) Analyzer ECG Feature Extractor Online Biosignal Noise Reduction Data Logger Biosignal Logger OBJECTIVES To collect the respiratory database To study the apnea characteristics To detect and classify apnea To achieve maximum accuracy To design a respiratory signal simulation system CHAPTER 2 LITERATURE SURVEY 2.1 RESPIRATION DATA ACQUISITION, CONVERSION AND DISPLAY SYSTEM 2.1.1 Methodology Respiration data is acquired and converted into a series of pulses, the frequency of which is related to the respiration rate of the data measured . The output pulses switch a timing device on and â€Å"off †, and the average time of a respiration cycle is then converted and displayed as respiration rate. The timing device includes a means for delaying a first output pulses before beginning the sampling period and registering a count of clock pulses for a specified number which represents the time period of a second specified number of the output pulses occurring subsequently to the first specified number of output pulses. 2.1.2 Conclusion This invention relates to an acquisition unit for acquiring data relating to one or more physiological variables from a patient. Displaying the data digitally and, upon operator approval, recording the data in an internal memory. Further, the invention relates to a data storage system responsive to data stored in an acquisition unit for a display presentation. 2.2 METHOD AND APPARATUS FOR DETERMINING A RESPIRATIONPARAMETER IN A MEDICAL DEVICE Shrivastav, Maneesh, Cho, Yong K., Bennett, Tommy D., Erickson, Mark K., Greenhut, Saul E., Kleckner, Karen J., Sperling, Charles P., Corey, Robert A. 2.2.1 Methodology A pressure sensor senses pressure signals, and a signal processor, coupled to the pressure sensor, receives the sensed pressure signaland generates corresponding sample points. A microprocessor continuously adjusts a breath detection threshold in response to the generated sample points to generate a current adjusted breath detection threshold. Then it compares a current generated sample point to the current adjusted breath detection threshold, suspends the continuous adjusting of the breath detection threshold. Then the microcontroller sets the breath detection threshold equal to the most current adjusted breath detection threshold generated prior to the suspending, and determines the respirationparameter in response to a comparing of a next generated sample point to the set breath detection threshold. 2.2.2 Conclusion This invention relates to a method of acquisition of respiratory signal using pressure sensor and displays that respiration parameter using a microcontroller. 2.3 METHOD AND APPARATUS FOR MONITORING RESPIRATION Rymut, Russell, Slotty, Eric, Kini, Narendra 2.3.1 Methodology The apparatus includes a piezoelectric film which converts acoustical waves generated by the patients respiration activity into electrical signal output. The piezoelectric film sensor placed in the subject can be used to monitor the respiration of a patient by correlating the sound generated in the patients airway with respiratory activity. Further, the data generated by the sensor may be further analyzed by a patient monitor to diagnose respiratory conditions and display it. 2.3.2 Conclusion This invention relates to a method and apparatus for monitoring and quantitatively measuring the respiration of a patient , particularly, using a flexible piezoelectric film sensor. 2.4 APNEA MONITOR Guixian Lu 2.4.1 Methodology 1. A conductive rubber string is used to measure the chest volume changes. It is not suitable for OSA. In that case a differential gas flow sensor is used. The output of the sensors is amplified and then fed to a re-shaper. 3.The re-shaper re-shapes the signal and generates pulses to trigger the counter. 4.The counter triggers the alarm circuit if the count exceeds a predetermined threshold. 2.4.2 Conclusion For adults one rubber string is enough. But for infants, the frequency of the body movement is measured. So an additional rubber string with motion detector is needed. The gas flow sensor is reliable and sensitive. A buzzer is used to give alarm. 2.5 DESIGN AND IMPLEMENTATION OF A PROGRAMMABLE APNEA MONITORING SYSTEM Mustafa ÇavuÅŸoÄŸlu, Osman EroÄŸul , Ziya Telatar 2.5.1 Methodology Respiratory signal is perceived by a thermal sensor. The signal is amplified and then fed to the microcontroller. The output of microcontroller is transferred to the computer and the relation between ECG and the signal is evaluated. An alarm system is also provided to indicate apnea 2.5.2 Conclusion The system is capable of detecting apnea, warns during the apnea and transfers the respiration signals to the computer. Finally,categorization of the apnea intervals is done to generate a real-time histogram of their frequency and duration which makes possible to investigate the relations between the EEG, ECG or other physiological signals and the respiratory patterns. 2.6 APNEA ALARM SYSTEMS 2.6.1 Methodology A crib or bed with piezo electric or strain gauge transducer attached to each leg is used to acquire the movement of infants. Whenever the infant is breathing there is a variation in the force distibution in the foam mat, so the vertical force applied on the frame of the crib also varies,which is captured by the sensors attached to the leg of the crib. These sensors convert the force into an electrical output signal and gives it to a summing amplifier to provide a summed output signal from all four legs. The summed output is given to a microcontroller where it is compared with the patients physical parameters to give an alarm if there is apnea detected using a buzzer or flashing light. 2.6.2 Conclusion This apparatus helps to detect apnea in infants who can be monitored even at home instead of hospitals.This alarm system is more comfortable to babies as it does not attach any sensor to infant s body.Mainly used to detect death due to apnea (‘crib death or ‘cot death ) very common in premature infants. 2.7 APNEA MONITOR DATA SYSTEM 2.7.1 Methodology An apnea monitoring system along with a portable data storage cartridge is presented. Respiration is monitored through the electrodes located on the thoracic cavity of the patient. Detected events are compared with respiration rates and when it is exceeded the signal is transmitted to audio and visual alarms indicating apnea. In addition to that a poratable data storage cartridge is provided which has enough memory to store all monitored events and waveforms that can be transferred to computer. 2.7.2 Conclusion This invention not only helps to monitor also contains a portable cartridge,that can be easily carried or mailed,which makes it time efficient and cost efficient method to store data.Another advantage is that the cartridge is replaceable,which provides an unlimited amount of memory space that helps in transfer of data. 2.8 A MODEL ANALYSIS OF ARTERIAL OXYGEN DESATURATION DURING APNEA IN PRETERM INFANTS Scott A. Sands, Bradley A. Edwards, Vanessa J. Kelly, Malcolm R. Davidson, Malcolm H. Wilkinson, Philip J. Berge 2.8.1 Methodology Independent influence of clinically relevant cardiorespiratory fators on the desaturation of arterial oxygen during apnea is determined using a two-compartmental lung-body mathematical model which incorporated realistic oxygen stores and gas exchange dynamic Analytic solutions were derived for arterial oxygen desaturation to quantify the importance of cardiorespiratory factors on arterial oxygen desaturation such as cardiac output, lung volume, metabolic oxygen consumption, pre-apneic ventilation, blood oxygen affinity, hemoglobin content and blood volume The model analysis reveals that lung volume, hemoglobin content, cardiac output, pre-apneic ventilation exerts a unique effect on arterial oxygen desaturation throughout the time-course of desaturation and metabolic oxygen consumption is uniformly influential throughout the process. Infants with elvated metabolic needs and low lung volume and those with anemia, cardiac dysfunction or hypovolemia which are common in prematurity are at heightened risk of rapid and profound arterial desaturation during apnea. 2.8.2 Conclusion A mathematical framework for quantifying the relative importance of key cardiorespiratory factors on the rate of arterial oxygen desaturation during apnea with particular relevance to preterm infants is provided. Each of the factors examined has a signature influence on the trajectory of desaturation, providing quantitativeinsight into the causes of rapidlydeveloping hypoxemia during apnea have been demonstrated. 2.9 OBSTRUCTIVE SLEEP APNEA AS A RISK FACTOR FOR STROKE AND DEATH H. Klar Yaggi, M.D., M.P.H., John Concato, M.D., M.P.H., Walter N. Kernan, M.D., Judith H. Lichtman, Ph.D., M.P.H., Lawrence M. Brass, M.D., and Vahid Mohsenin, M.D. 2.9.1 Methodology 1.In this study patients underwent polysomnography and subsequent events like stroke and death are verified. 2.The diagnosis was based on apnea-hypopnea index of the patients.Patients with apnea-hypopnea index of less than 5 served as a comparison group. 3.Proportional hazards analysis was used to determine the independent effect of OSA syndrome on the outcome of stroke or death from any cause. 4.The mean apnea-hypopnea index for the patient with syndrome is 35 while the same for patients in the comparison group is 2. 5.After adjustment for age,sex, diabetes mellitus, smoking status, alcohol consumption status, body-mass index, hypertension, the OSA syndrome retained a statistically significant association with stroke or death. 2.9.2 Conclusion The obstructive sleep apnea syndrome significantly and severely increases the chance for stroke or death from any cause. The increase for the risk of stroke or death due to OSA syndrome is independent of the other risk factors,including hypertension. 2.10 AN ECONOMIC ANALYSIS OF CONTINUOUS POSITIVE AIRWAY PRESSURE FOR THE TREATMENT OF OBSTRUCTIVE SLEEP APNEA-HYPOPNEA SYNDROME Helen L. A. Weatherly, Susan C. Griffin, Catriona Mc Daid, Kate H. Durà ©e, Robert J. O. Davies, John R. Stradling, Marie E. Westwood and Mark J. Sculpher. 2.10.1 Methodology This study reports on the cost-effectiveness of the continuous airway-pressure(CPAP) compared with the dental devices and lifestyle advice to the patient. The Markov model compared the interventions over the patients life expectancy. The primary measure for cost-effectiveness was the incremental cost per quality adjusted life-year(QALY) gained for every patient. On further analysis, CPAP was associated with higher costs and QALYs compared with dental devices and lifestyle advice. The result of analysis was that the probability that CPAP is more cost-effective than dental devices or lifestyle advice at a threshold value of  £20,000 per QALY was 0.78 for men and 0.80 for women. 2.10.2 Conclusion This model suggests that CPAP is cost-effective compared with dental devices and also the lifestyle advice for adults with moderate or severe symptomatic Obstructive Sleep Apnea -Hypopnea Syndrome are at the cost-effectiveness thresholds used by NICE. This finding is reflected in the NICE guidance. CHAPTER 3 METHODOLOGY 3.1 EXISTING METHODS Several contactless methods are available for monitoring the respiration of infants. The most successful apnea monitors to-date been mattress monitors. These instruments rely for their operation on the fact that the process of breathing redistributes an infants weight and this is detected by some form of a pressure sensitive pad or mattress on which infant is nursed. The mattress, in its simplest form, is a multi-compartment air bed, and in this case the weight redistribution forces air to flow from one compartment to another. The air flow is detected by the cooling effect it produces on a heated thermistor bead. Though the technique is simple, the main disadvantage with the air mattress is the short-term sensitivity variation and the double peaking effect when inspiration or expiration produces separate cooling of the thermistor. Alternatively, a capacitance type pressure sensor in the form of a thin square pad is usually placed under or slightly above the infants head. Respiratory movements produce regular pressure changes on the pad and these alter the capacitance between the electrode plates incorporated in the pad. The capacitance change is measured by applying a 200 kHz signal across the electrodes and by detecting the current flow with a phase-sensitive amplifier. The disadvantage of this method is that the system is much too sensitive to people moving nearby and thus an electrically screened incubator is essential for the infant. 3.1.1 METHOD ADOPTED This project is based on impedance pneumography method. Impedance pneumography is one of the practical methods to monitor the breathing of the patient. The technique also enables the simultaneous monitoring of the heart rate and respiration. This has certain inherent disadvantages. One is that the placement of the electrodes is very critical and other is cardiovascular artifact. This results from the detection of movement between the electrodes because of the cardiovascular system, rather than due to respiration. Apnea monitors need to be designed to reject this artifact. So in this project the respiratory signal is considered to be acquired by using respiratory sensor. As there is no availability of sensor, respiratory signal is simulated using our own designed impedance pneumography technique based circuit. Then this signal is given to microcontroller where apnea is detected and it then triggers an alarm. The classification of apnea is also done using LabVIEW. In future respiratory sensor will be designed and the respiratory signal will be acquired. Then this signal can be given to the microcontroller directly. 3.2 RESPIRATORY SIGNAL SIMULATION The respiratory signal simulation circuit consists of an excitation source and a constant current source circuit which gives a high frequency, low voltage and constant current signal. This constant current will be applied to the thorax of the subject. But due to the ethical issues the current is applied on the resistance circuit which acts as the thorax impedance. This circuit in turn gives a voltage signal. This voltage signal will be amplified by an instrumentation amplifier. The amplified signal will be fed to the LabVIEW for classification of normal and apnea signal and also types of apnea. Figure 3.2.1 shows the block diagram to simulate respiratory signal and the hardware design of the circuit 3.2.1 EXCITATION SOURCE The wien bridge oscillator which produces 50kHz and 8 V peak to peak signal is used as the excitation signal. The operational amplifier used in the circuit is LF351. The Voltage gain of the amplifier must be at least 3. The input resistance of the amplifier must be high compared toRso that theRCnetwork is not overloaded and alter the required conditions.The output resistance of the amplifier must be low so that the effect of external loading is minimized. Some method of stabilizing the amplitude of the oscillations must be provided because if the voltage gain of the amplifier is too small the desired oscillation will decay and if it is too large the waveform becomes distorted 3.2.2 CONSTANT CURRENT SOURCE The constant source circuit is used to generate a 4mA constant current to be applied on the resistance circuit. CL100 and CK100 transistors are used in this circuit and these are npn and pnp paired transistors. The base emitter on voltage of these transistors is 0.9V. The collector current can be found by using the formula, Ic= (Vcc-Vbe)/Rc Where Vcc-Supply voltage Rc-Collector Resistance Vbe-Base emitter on voltage 3.2.3 PHANTOM MODEL The model consists of four resistors of 500 ohms which mimics the thoracic resistance. 3.3 DATA COLLECTION To know about characteristics of normal respiration and apnea their corresponding signals were essential. So 40 respiration data sets with 100 sample values in each data set were collected from PHYSIONET -PHYSIOBANK ATM. Among these 20 were normal data sets obtained from SLEEP HEART HEALTH STUDY POLYSOMNOGRAPHY DATABASE (SHHPSGDB) while the other 20 were apnea data sets obtained from UCD SLEEP APNEA DATABASE (UCDDB). In Apnea data sets 10 belonged to Central Sleep Apnea and remaining 10 to Obstructive Sleep Apnea. Each Data set contained 100 samples whose units are volts(V).They were recorded for 100seconds.So on plotting each data we get time in X-axis and volts in Y axis. 3.4 CLASSIFICATION OF APNEA USING RESPIRATION RATE Input data which contains 60 samples each. Normalizing of the signal by squaring the signal. Extraction of maximum peak for every 5 samples.Display of respiratory cycles. If the peak value is greater than 6V it will be counted as normal respiratory cycle. If the count is between 10 and 20 the signal will be having normal respiratory rate. If the count is less than 10 the signal will be classified as bradypnea. If the count is greater than 20 the signal will be classified as tachypnea As the parameter of respiratory rate alone is not enough for classifying the types of apnea the statistical parameters are calculated and then signals are classified using LabVIEW. FLOWCHART 3.5 CLASSIFICATION OF APNEA USING STATISTICAL PARAMETERS The signal data was imported from a spread sheet into labview using READ FROM SPREADSHEET block in labview. Then signal was plotted as a graph using WAVEFORM CHART block. The data cannot be manipulated directly so the transpose of the data is taken to find the statistical parameters using TRANSPOSE ARRAY block. Now using the STATISTICS block the signals various parameters like arithmetic mean, median, mode, maximum peak, minimum peak, range, standard deviation variance, and rms value are found and recorded. Considering the range and mean of the signal it can be classified as its respective type. Give the upper and (or) lower limit for range and mean. Now using AND operator the signal is classified when its condition are satisfied. When the signal s range is greater than 7 and its mean is less than 0.1 it is normal. When the signal s range is lesser than 6 and its mean is greater than 0.21 it is abnormal. When the signal s range lies below 3.0 it is obstructive. When the signal s rang e lies between 3.1 and 6.99 it is central. FLOWCHART CHAPTER 4 4.1 RESULTS AND DISCUSSION 4.1.1 Hardware Results Output from the excitation source (wein bridge oscillator) was checked in MULTISIM and then implemented using hardware. On applying the constant current to a resistance network that imitates human thoracic impedance , the current varied to a greater extent because of loading effect. The same problem will occur even when the patient is connected to the high frequency, low voltage, constant current module. Also, due to ethical issues the constant current generated cannot be given to the patient directly. So monitoring of real time data could not be done using the hardware design. Hence ,the idea of respiration signal simulation was dropped and offline data were collected from respiration databases for further classification. 4.1.2 Normal and Apnea Data To know about characteristics of normal respiration and apnea their corresponding signals were essential. So 40 respiration data sets with 100 sample values in each data set were collected from PHYSIONET -PHYSIOBANK ATM. Among these 20 were normal data sets obtained from SLEEP HEART HEALTH STUDY POLYSOMNOGRAPHY DATABASE (SHHPSGDB) while the other 20 were apnea data sets obtained from UCD SLEEP APNEA DATABASE(UCDDB).The Resulting plot for each type of respiration signal is plotted below. The following figure shows the normal respiration data plotted for 100 samples with time in x-axis and amplitude in y-axis with a maximum peak to peak voltage of 8V and 24 respiration cycles for 100seconds. The following figure 4.4 shows Ce

Use of Satire and Irony in The Widow of Ephesus and the poem True Love

Use of Satire and Irony in The Widow of Ephesus by Gaius Petronius and the poem â€Å"True Love† by Judith Viorst In the story The Widow of Ephesus by Gaius Petronius and the poem â€Å"True Love† by Judith Viorst, the authors portray love through the use of satire and irony. They do this though a series of ironic twists, humorous accounts, and life experiences. A satire is a literary work holding up human vices and follies to ridicule or scorn. In The Widow of Ephesus, the narrator recalls a tale of love in which an apparently faithful woman discredits her vows of marriage after her husband's death. She is tempted into this by a handsome young man, who attempts to save her life after she decides to entomb herself with her dead husband. This was not a very smart decision on her par...

Rosalind Franklin :: essays research papers

Rosalind Franklin Rosalind Franklin lived during an exciting and turbulent era both socially and scientifically. Upon passing the admission examination for Cambridge University in 1938, at fifteen, Franklin was was informed by her affluent family that she would not recieve financial support. Franklin ¡Ã‚ ¯s father disapproved of women receiving college educations, however, both Franklin ¡Ã‚ ¯s aunt and mother supported her quest for education. Eventually, her father gave in and agreed to pay her tuition. Franklin would later prove to be worth her education. As Rosalind Franklin was pursuing her degree World War II raged. She focused her research on coal, the most efficient use of energy resources. Five papers on the subject were published before Franklin ¡Ã‚ ¯s 26th birthday. Further, Franklin had given up her fellowship to become a physical chemist at the British Coal Utilization Research Association at age 22. She was indeed an efficient and driven researcher. Franklin utilized the X-ray diffraction techniques (that she has become most famous for) while working in a Paris laboratory between 1947 and 1950, with crystallographer Jacques Mering. X-ray crystallography helped determined the three dimensional structure of DNA when Franklin returned to England. She became the first person to find the molecule ¡Ã‚ ¯s sugar-phosphate backbone while working with a team of scientists at King ¡Ã‚ ¯s College in London. Unfortunately, leadership misunderstandings and personality conflicts depreciated Franklin ¡Ã‚ ¯s effectivness in the laboratory. Maurice Wilkins, the laboratory ¡Ã‚ ¯s second in command, returned from a vacation expecting Franklin to work under him. Franklin came to the laboratory with the understanding that she would be researching alone. While Franklin was direct and decisive, Wilkins tended to be alluding and passive-aggressive. As Franklin made further advances in DNA research, Wilkins secretly shared her findings with the famous duo of Watson and Crick, who were then working at Cambridge. Franklin ¡Ã‚ ¯s discoveries fueled their research machine, allowing them to advance beyond others in the field. T hey would eventually publish on DNA structure in 1953. Due to discriminatory procedures at King ¡Ã‚ ¯s College, Franklin eventually left to become the lead researcher at London ¡Ã‚ ¯s Birbeck College--upon agreeing not to work on DNA. She furthered her studies in coal and made significant advances in virology. Franklin died in 1958 of ovarian cancer. She lived 37 monumentally significant years. After researching Rosalind Franklin ¡Ã‚ ¯s scientific career, I truly believe that she was a pioneer rather than a follower. Her early coal work is still referred to today; she helped launch the fields of high-strength carbon fibers; and was an integral part of early structural virology.

Unbridled Ambition in Shakespeares Macbeth Essay -- Macbeth essays

Unbridled Ambition in Macbeth      Ã‚  Ã‚   Where is there a page in William Shakespeare's tragic play Macbeth which does not present the selfish virtue of personal ambition. This paper addresses the problem of ambition in the drama.    In "Memoranda: Remarks on the Character of Lady Macbeth," Sarah Siddons mentions the ambition of Lady Macbeth and its effect:    [Re "I have given suck" (1.7.54ff.)] Even here, horrific as she is, she shews herself made by ambition, but not by nature, a perfectly savage creature. The very use of such a tender allusion in the midst of her dreadful language, persuades one unequivocally that she has really felt the maternal yearnings of a mother towards her babe, and that she considered this action the most enormous that ever required the strength of human nerves for its perpetration. Her language to Macbeth is the most potently eloquent that guilt could use.   (56)    Clark and Wright in their Introduction to The Complete Works of William Shakespeare interpret the main theme of the play as intertwining with evil and ambition:    While in Hamlet and others of Shakespeare's plays we feel that Shakespeare refined upon and brooded over his thoughts, Macbeth seems as if struck out at a heat and imagined from first to last with rapidity and power, and a subtlety of workmanship which has become instructive. The theme of the drama is the gradual ruin through yielding to evil within and evil without, of a man, who, though from the first tainted by base and ambitious thoughts, yet possessed elements in his nature of possible honor and loyalty.
