Universal RELATIONS AND POLITICS - Essay Example The term of dominion is normally applied when talking about such nations as the United Kingdom, the USA, Japan, Italy, Spain and France of the nineteenth century. In that time these nations were attempting to establish realms by claiming zones in Africa. This procedure is known as â€Å"the Scramble for Africa†. In his work dated 1916 â€Å"Imperialism, the Highest phase of Capitalism† Lenin expounded on the significance of building the solid entrepreneur domain that will treat different countries and will have enough capacity to take choices on the world field. As per him, colonialism infers the control of the created nations over the immature ones, (for example, African districts). In spite of the fact that it must be referenced that realm building and the longing to catch different terrains has consistently been in the history, the Lenin’s government was a particular one as a result of the industrialist premise. Free enterprise is established on the possibilit y that all the force is controlled by private proprietors and capital represents the key component in the monetary framework. Inside the turn of the nineteenth century the private enterprise in such nations as France, Japan, the USA and the UK was portrayed by an extraordinary number of imposing business models. Lenin wrote in his show that the little exclusive organizations that were the key factor of the country thriving as indicated by Karl Marx were to be supplanted by the large imposing business models that would have less proprietors, and at the end of the day, less individuals controlling it. Such mammoths of creation or different business controlled the entire country with the assistance of the force that capital provided for them. Indeed the predominant components of the economy â€Å"capital, land and riches were amassed in the possession of the few† (Greene, 1970). Lenin expressed: in the event that it was important to give the briefest conceivable meaning of gover nment, we ought to need to state that dominion is the restraining infrastructure phase of private enterprise (Greene, 1970). Along these lines, when the economy of one nation makes progress toward imposing business model, it prompts the lessening of rivalry. In some time such circumstance in one state can extend to the global field. So as to make sure about the force, capital and their proprietorship those couple of individuals required the help of the state. Any security suggests substantial spending on military powers. As indicated by Lenin’s hypothesis, the imposing business model of the capital prompts the military reinforcing. The pace of a country’s security relied upon its military and naval force powers, and it in its turn relied upon the mechanical creation that gave these divisions. Therefore the interests of restraining infrastructures and state connected together and there seemed intense relationship. As indicated by Bukharin, the partner of Lenin, the impo sing business model of economy prompts its internationalization, however this internationalization was to be eased back by the equipped countries that secured their proprietorship and capital savagely. Along these lines, there was the need for a state to help out different nations, yet it was to be done cautiously all together not to hazard the state security. As Lenin clarified, Free enterprise's change to the phase of syndication private enterprise, to fund capital, is associated with the strengthening of the battle for the dividing of the world (Warren, 1980). As referenced over the new influx of dominion dependent on private enterprise was established on the scramble for feeble districts so as to give

IAP No.. YOURE AP

IAP No.. YOU’RE AP (Yeah, okay, that was a really bad title. I GET IT. Not everyone can have their neighbors be eaten by countries, have entries dedicated to them in conjunction with Bens mom, etc.) IAP began a little over a week ago and stands for Independent Awesome Period (not really, but it might as well). Im taking the EMT class, which is not only an amazing deal (we only have to pay for the cost of our book this year, while EMT classes at other campuses can cost several hundreds of dollars and take much more time) but also an intense 8-hour daily triathalon of taking quizzes, listening to lectures, and training in the afternoon. (Its also the reason why this post is so late.. Im really tired by the time I make it crawling and bruised, limbs hanging off in stray directions, back to my dorm.) Our professor/teacher/instructor guy/lets just call him Mark is an active man with the power to withstand our classs constant poking and prodding, as long as he gets to bite back. Aside from class, theres a huge variety of different activities, lecture series, and crash courses you can take during IAP, which Melis talked about earlier, or you can just enjoy yourself, because a lot of people have substantially smaller workloads. Yesterday I saw Monets water lilies up close at the Museum of Fine Arts in Boston, then went shopping on Newbury Street; a few nights ago I had dinner at California Pizza Kitchen with Trevor, Aditi, and Christina during which we revealed embarassing personal secrets such as Trevors love for the chick flick A Lot Like Love. We then proceeded to attempt to watch it in the Simmons multipurpose room. (Attempt only, because very tragically, the projector was broken. Poor Trev.) Enough about my happenings, though. You have questions! I have answers and droolworthy pictures. (This isnt really a fair trade, is it?..) Ella ponders: I read what you wrote in a previous entry (er..I think it was October..?) about being evaluated as a person and your personality, not your record alone, but it just seems so important to have a good portfolio and everything. I dont live in America right now but Id love to go to MIT and it just seems like theres so much competition, everyones just trying to shove as much as they can under their belt. Does that actuallywork? Blahh, I hope not. Id like to think it doesnt. But I know it happens, and it sucks. People join like, blind pistol clubs or something else equally useless that they dont care about all the time just to put it on their college applications. This is bad. You can, however, actually benefit from these types of peripheral activities, though, if you genuinely diversify your interests in this manner genuine being the key word. If you do, itll hopefully show through in your essays and your interview. A really important thing to remember is that youre not evaluated on anything alone. Yeah, its great if youre a really funny kid with an optimism like nobodys business, but thats not going to compensate for a complete lack of extracurriculars and a 400 on the SATs and vice versa. Dont go too crazy with diversifying yourself, though, just because everybodys doing it the competition is always going to exist whether you conform to it or not. And yes, people living in America might have different opportunities available to them as well, and thats fine the admissions office will recognize that this exists. Dont let it get to you! Monica queries: I have been wanting to got to MIT since I was little, do you have any advice or tips to help me? Right now I am in the 8th grade. And what exactly is a problem set? Take challenging classes that interest you at the same time. This is kind of hard, especially in high school, because a lot of the time you just have to go through the motions. If you find yourself getting bored by the monotony (and you probably will), do something new. Start a club. Enter a science fair. Take a class at a community college. Learn how to manage your time efficiently. Beat up anyone who gets in your way. (Dont actually beat up anyone who gets in your way.) Above all, high school can actually be pretty rewarding if you dont get sucked into the everyday routine. Enjoy yourself! Make friends with everybody! Run around screaming! Dont actually run around screaming! Best of luck! (Regarding problem sets: Theyre homework, usually assigned weekly. Christina answered this pretty well: You know how in high school youre given, say 1-21 odd? A problem set at MIT consists of 1-23049234 ALL and then a bunch of tricky questions the professor makes up him/herself. Theyre wonderous.) Josh V questions: so i just read that youre a swimmeron a team? what do/did you swim? its all about the 100 fly for me (and unfortunately somtimes the 200 im-ugh!) do you swim for mit? varsity? do they have club or jv teams at mit? (because im def no varsity swimmer) also, whats it like being asian at mit? do you not even think about it? do you just go with the flow and chill like everyone else? and i only ask because my elementary/middle school was pretty much an all filipino (maybe like 70-80%) school, and when i moved to seattle prep (my hs), it was like 70% caucasian so it was kind of a big change and major deal to me and i noticed it not frequently, but often. and because im also in the multicultural club and i think about things like that. I swam for my high school JV team and on a summer rec team; around my senior year I practiced with a year-round, but Im really out of shape now so I swim on my own. I believe the 200 IM is actually used as a form of torture in some parts of the world. (No, not really. I hate it, though.) MIT does have a varsity swim team and a masters team, as well as a REALLY nice olympic pool thats pretty much open to anyone as long as you have a gym membership. As for the Asian question, Im kind of confused as to what you mean because the typical stereotype is that theres a lot of Asians at MIT, but I feel like youre asking me if I feel differently as an Asian person in a non-Asian environment. (Feel free to correct me if Im wrong, though you said chill like everyone else as in chill like everyone else who is not Asian?) Let me put it this way. To me, being Asian at MIT is like being Asian at a grocery store. Or being Asian at a Holiday Inn. Or being Asian in a tree. There is no difference. I am an American, and a human being, and I have friends that are other human beings that happen to be white and brown and black and yellow and orange and green and blue. This might be something important to digest before you go to college, MIT or not. Ashley asks: How is food in MIT? I remember you writing about that amazing sandwich, but you cant eat that sandwich everyday for 4 years. Do you cook/make your own meals? Do you have time to fit all your extracurricular activities and workload in your schedule? You did write about tons of activities, but are you still involved in those activities while finishing up your problem sets? Ashley, you can if you continue to discover amazing sandwiches. This is, however, providence, and not something that we can control. To be honest, Im not a big fan of the food at MIT, but college food in general is a big step away from home cooking. The great thing is, though, were so close to Boston that its really easy to go out and find really good restaurants, like the incredible Flour Bakery on Washington Street where my sister and I found those really awesome sandwiches (hers is egg; mine is caprese), or even at the CambridgeSide Galleria, the mall that has your bigger chain restaurants like the Cheesecake Factory, and of course, California Pizza Kitchen. Its funny that you just asked me about cooking, though, because over IAP theres only one dining hall open that is a lot pricier than just cooking your own food, and a bunch of my friends decided that we were sick of eating bread sandwiches (that would be bread in between two slices of bread) for dinner, so we headed out to the grocery store to buy enough food for 8 people for one week. A lot of people do cook during the year the residents of French House cook every night and have an awesome fully-stocked kitchen, but Next House only has one big kitchen in the basement and a dining hall, so its not as much a priority. Cooking can be hard during the year, though, with all your other commitments. It IS kind of hard to deal with balancing your activities, especially when you come from high school and youre used to doing five million things at once because all you have to worry about is whether you want an A or an A++, and then you come to college especially MIT- and the workload is a lot different from what youre used to. Even those kids who got straight As, were president of the Computer/Chess/Computer Chess club, ran varsity track and field, wrote a movie critique column online, played the panflute, and still had a social life have to learn to adjust. I did eventually drop out of Concert Chorus because of the five-hour practices, but I was still a member of MedLinks, Plush Daddy Fly, Dance Troupe, and now Im training to be an EMT, but I really value each of my activities for different reasons. So yeah, if you dont spread yourself too thin, extracurriculars are not only manageable, theyre really wo rthwhile. You could start over entirely at college and become a yoga master or something. Put down your panflute. I think Im trying to be metaphorical here. Its not really working out. Next! Amy scrutinizes: I was just curious a while ago you posted about getting a new Macbook. Whats it like switching from a PC to a Mac and how does it fit into an MIT-style life? Are you liking it so far? Do computers play a big part in life in general at MIT, or just for Course Six-ers? I went home for break two weeks ago and took my MacBook home. I set it up in front of my PC, on the desk, and nine times out of ten went for the laptop instead of the gigantic machine running Windows that Id used for two years with the double monitors and the subwoofer and the spacious hard drive. I dont really function without my MacBook, seriously. Switching from a PC to a Mac was pretty much a no-brainer, and the interface is much, much cleaner but then again, it often comes down to personal preference. Computers in general play a big part in college life, MIT or not; youre going to be writing papers and checking your email (and facebook) every two seconds, anyway you might as well get one you love. So I told you how I was really pressed for time during the week with the EMT class, right? Ive been trying to post this for the last four days to the extent that Im finally putting this up during my lunch break. Im so late getting back to class, though Mark is probably going to sit on me so Ill see you in four hours!

Viktor demonstrated all three methods which was fascinating. These popular devices were inspired in the nineteenth century by Peter Mark Roget’s theory of visual persistence, which held that our eyes retain an image for a fraction of a second, permitting a series of still images to become â€Å"fused† as a moving image. Another way to break down movements into a series of still pictures is a so called â€Å"video flipbook†. A flipbook is the simplest way of making a sequence of still pictures appears to move. The intervals of darkness necessary for the illusion of motion are provided by the turn, or flip of each page. The nineteenth-century photographic experiments of Eadweard Muybridge and Etienne-Jules Marey broke down the movements of animals into a series of still pictures. When displayed in rapid succession, these pictures appear to be moving, recreating the original motion that the images document.

After testing two participants blood pressure and respiration rate, it was found that the vital signs of the participants remained the same after consuming water but decreased slightly after consuming coffee. This lab is significant because it demonstrates that the consumption of coffee, on the contrary to Group 4’s hypothesis, caused a decrease in the vital sign measurements of the two participants rather than increasing as we initially hypothesized. We will write a custom essay sample on Lab Report or any similar topic only for you Order Now This lab was done to determine and compare the effects that coffee drinking has on blood pressure and the respiration rate in two participants. The hypothesis configured by our group was that after drinking 1 cup of water the participant’s blood pressure and respiration rate would remain constant, but after the drinking 1cup of coffee the participants blood pressure and respiration rate would increase as a result of the common compounds found in coffee. The control in this experiment is 1 cup of water, because the participant’s blood pressure and respiration rate are being measured, but they have not been exposed to the common compounds found in coffee. The dependent variable in the study is the participant’s blood pressure and respiration rate because the vital signs are the component in the experiment that are being measured. The independent variable is what is changed in the experiment and in this experiment that would be the amount of the common compounds the participants consume in 1 cup of coffee. The results of our lab disproved our hypothesis, that consuming coffee would increase the participant’s blood pressure and respiration rate, as seen in Table 1, Graph 1, and Graph 2. Although our expectations of the measurement of vital signs after consuming 1 cup of water were correct, we had expected the results from the measurement of both the respiration rate and the blood pressure to noticeably increase after consuming coffee due to the common compounds found in coffee. The lab, actually, resulted in the decrease of respiration rate and blood pressure after the consumption of coffee. The study preformed by the National Cancer Institute measured the association between coffee and its affects on health, as a result of reading this article I conducted a study that worked off the same principle. However, in the lab I attempted to narrow the causal relationship between the two by measuring the participant’s vital signs, respiration rate and blood pressure, in relationship to consuming coffee versus water and any potential periods or repeated periods of evaluated or descended vital signs has to the longevity of one’s life. The results of the lab support the findings of the National Cancer Institute because the article states that consuming coffee has positive affects on health and our lab concluded that coffee consumption lowers blood pressure, which is necessary for a person that may struggle with high blood pressure to become healthy. During the lab, the participants physiology, blood pressure and respiration rate, was lowered after consuming coffee, this served to calm the participant’s vital signs. To improve the validity of the study a few changes could be made to improve the results. For example, I believe that the vital signs were not effected greatly because of the time span used to complete the study, after drinking the coffee we immediately took the vital signs instead of waiting for the full effect to take place. An additional reason for the higher levels of the vital signs before the consumption of coffee could have been due to activities done prior to the lab thus increasing the vital sings measured after drinking water. To improve upon these imperfections, the study could be done earlier in the day and with more resting periods before vital signs are taken. This lab was designed to determine the relationship between coffee consumption and two types of vital signs, respiration and blood pressure. The lab measured the respiration rate and blood pressure of two participants, once after consuming water and then again after consuming coffee. I hypothesized that the consumption of coffee would dramatically increase the participant’s respiration rate and blood pressure due to the consumption of the common compounds found in coffee that typically raise energy levels and alertness. However, the lab resulted in slightly lower respiration rates and blood pressure after the consumption of coffee than water as seen in Table 1, Graph 1, and Graph 2. The lab is significant because it demonstrates that the consumption of coffee, in contrast to our hypothesis, caused a decrease in the vital sign measurements of the two participants rather than increasing as we originally hypothesized.

We will write a custom essay sample on Lab Report or any similar topic only for you Order Now Then we will learn about the easiest way to locate the star Polaris. As we started the first program, we answered a few questions to make sure we knew the general idea of stars. Then we labeled the altitude and azimuth of five objects. Aldebran had a altitude of 54o and an azimuth of 203o. Betelgeuse had an altitude of 47o and an azimuth of 203o. Castor had an altitude of 62o and an azimuth 118o. Deneb had an altitude of 13o and an azimuth of 328o. Elnath had an altitude of 68o and an azimuth of 184o. After that, we looked at the right ascension and declination (RA and DEC). Aldebran had a RA of 4. 6 hours and a DEC of 16o. Elnath had an RA of 5. 3 hours and a DEC of 28o. Betelgeuse had an RA of 5. hours and a DEC of 8o. Castor had an RA of 7. 6 hours and a DEC of 32o. Deneb had an RA of 20. 7 hours and a DEC of 46o. Finally we looked at the Big Dipper and the Cassopia to find the star Polaris. This lab was super cool, I loved it. The planetarium was great way to learn more about the different constellations and stars in the sky. I never knew that Polaris was so close to the Big Dipper. Finding the all the right ascensions and declinations of the objects wer e fairly easy and felt like I learned to do it pretty easily now.

Repeatability measurements were taken on a bolt to get the total length, and also measuring the low rate of a faucet by measuring the amount of time it took to fill a beaker. To ensure a more accurate sample, twenty measurements of each section were obtained. For the batch measurement portion of this lab, a multi-meter was used to measure the resistance in a pack of ten resistors. We will write a custom essay sample on Lab report or any similar topic only for you Order Now Each member measured the resistors twice to allow for more precise statistical analysis. After all measurements were recorded, statistical analysis such as mean, standard deviation, and true mean range with 90%, 95%, and 99% confidence intervals were used to obtain the results. Once calculations were made, it was determined that there was error in this vibratory due to the environment and to human error, however all of the results fell within the ranges of confidence for each given section. Relevance In this experiment length, flow rate, and resistance was measured and the true mean was calculated. It was observed that the true mean varied depending on the variation of the sample mean and sample standard deviation. It was shown that the population mean, or true mean, could not be found exactly, but could be estimated as a range with a certain level of confidence with the measurement of the sample mean and sample standard deviation. The knowledge practiced in this lab can be lawful in future experiments if say a company needs to estimate the population average with a specified level of confidence of a bolt that they only have a few samples of. Introduction There are multiple ways of measurement, as well as, many different types of ways to analyze raw data. In this lab the objective is to experiment with two different types of measurements, repeatability and batch measurements. Theoretically the bolt length plus the cap thickness (B+C) should be equal to the measured total length of the bolt(A). Taking multiple measurements done by multiple people until twenty samples re obtained measuring all four components of the bolt and obtaining the raw data of bolt measurements. By having multiple people take measurements a small amount of human error is removed in case one person didn’t measure as accurate. By having multiple measurements done by each person a bigger sample size is obtained, and bigger sample size typically means more accurate results. After the measurements were made a sample mean was calculated, as well as, a sample standard deviation for all four components of the bolt. The sample mean and sample standard deviation were 2 lactated to estimate the true mean of the population with a level of confidence of 90 and 95 percent. Once the true mean of each component was estimated a comparison was made between the total length(A) and the sum of the cap thickness(S) and bolt length(C). In theory (B+C) should equal the total length of the bolt(A), as they represent the same length. Though they should be the same, they are not. The sum of measurements, (B) and (C) yield a much wider range of true mean than the measurement of (A). This difference is created by multiple types of error such as, human error, maybe reading the caliper wrong. Or error such as mechanical error, maybe the caliper itself was broken or not calibrated. In the second module of this lab the flow rate of the faucet water is measured using a stop watch and a mall beaker. Obtaining the flow rate of the water in 20 different samples, then summarizing the raw data into sample mean and sample standard deviation. With the sample mean and standard deviation, the true mean is to be estimated with a confidence level of 90 percent and then again with 95 percent. In the third module the measurements were made in batches. The measurements of batches of resistors were measured with a Center Multi-meter to make sure they all locked in at the same resistance. The resistors measured in this lab were quite strong, getting up to kick. Each group member measured the batch of resistors twice, then a pooled mean and pooled standard deviation was calculated. Pooling all the members samples together gives us one large sample and a more accurate estimate of the true mean. Using these calculated pooled mean and standard deviation the true mean was found as a range with a 99 percent level of confidence, and then again with a 95 percent level of confidence. The experimental setup and procedures are described in section The results of the experiments can be found n section {V} followed by conclusions in section {VI}. The appendix with the data chart can be found in section{Veil} Testing the repeatability of the measurements and taking the sample average and sample standard deviation to compare with each other, as well as, estimate the population mean and standard deviation. In three different modules linear dimension, flow rate, and resistance were measured. The primary objectives of this lab are to practice using devices that measure length and flow rate, to apply statistical principles to raw data sets, and to become familiar with use off multi-meter. Formulas Used: Sample Mean Standard Deviation True Mean Range 3 Experiment: Equipment: Pittsburgh 6†³ Caliper Bolt Cent-Tech Digital Multi-meter CTD 10 pack of electrical resistors (gold, yellow, red, yellow) mall Beaker Digital Stopwatch Procedure: This experiment utilizes the billeted above. The experiment is broken down into three sections. First take the caliper and the bolt, calibrate the caliper to make sure that accurate measurements are collected. Measure the complete length of the bolt, thickness of the head, width of the threads and the length of the bolt to the base of the head. Repeat the measurement a total of twenty times split evenly between the roof members and record the results. Second, take a mall beaker and a stopwatch to the sink and turn the water faucet on to attain a constant flow rate of water. Use the stopwatch to measure the time it takes from the first drop of water entering the beaker to the instant the water begins to overflow from the top of the beaker. You read "Lab report" in category "Papers" Empty the beaker of water repeat this measurement a total of twenty times split evenly between the group members and record the results. For the last portion of this lab, take a pack of resistors and the multi-meter. Set the millimeter to the appropriate reference resistance and begin measuring each of the sisters one at a 4 time. Each member will measure the set of resistors twice for a total of twenty resistance measurements per each member of the group. Record the measurements from each member and calculate the true mean resistance. Procedure Changes: The only change/ improvement made to the experiment was during the batch measurement section. It was found that more accurate readings of each resistor could be attained by taping the resistor pack to the table to keep it in place while using the probes to measure the resistance. This change will allow the group to move quicker through the experiment and not to make any mistakes such as possibly measuring the same resistor twice in a row. The experimental procedure is very straight forward and the group should not encounter any difficulties. Results/Discussion This lab required three different modules to be completed with two different types of measurements: batch and repeatability. The bolt measurement along with the volume flow rate were to be completed using repeatability, while the resistance module used batch measurements. The data was to be recorded and put into tables and analyzed using the mean, standard deviation, and true mean to determine whether the measurements were in the desired confidence intervals. 5 Linear Dimension Module: The first set of data was recorded using a manual caliper and a bolt. Four measurements were to be taken from the bolt: length, cap thickness, bolt length, and major diameter. These measurements lead to some error as expected, mostly human error and calibration of the manual calipers. There was also some error due to the uneven sides of the bolt and the angle at which the calipers were held against the bolt. Table la. Shows the summarized data falls within the 95% Confidence Interval. Measurement Total Length (A) Cap Thickness (B) Bolt Length (C) Major Diameter (D) B+C Sample Mean (in. ) (in. ) 2. 2661 0. 0033 0. 2825 0. 0031 1 . 9791 0. 0262 . 30327 0. 0007 2. 2616 0. 0268 Table la. Statistics of Bolt Measurements (95%) [2. 265, 2. 267] [0. 2810, 0. 2839] [1. 967, 1. 991] [0. 3024, 0. 3030] [2. 249, 2. 274] The second part of the linear module was to compare the difference between the total length (A) and the sum of cap thickness and bolt length (B+C). The results show that there was a lower CLC with the total length measurement than with the addition of two parts. This is most likely because of the accuracy of two measurements has more mom for error from the angle of the calipers and human error. Table b. Shows the comparison of the two measurements. The full experimental data for the linear module is listed in Table A in the Appendix. Table b. Comparison of bolt statistics Flow Rate Module: Measurement of the flow rate from a sink using a stopwatch and beaker was the second of the repeatability measurements. This module produced the most error most likely from human error with stopping and starting of the stopwatch. The inconsistent flow from the sink also contributed to some of the error. The standard aviation in this experiment was high, but after 6 calculating the true mean range for a 90% and 95% confidence interval, the sample mean falls within both ranges with a few outliers. Table LLC. Shows the summary of the data. The full experimental data is listed in Table B in the Appendix . (ECMA/min) 5300. 95 CLC (ECMA/metro) 138. 835 [5247. 27, 5354. 3] Table LLC. Flow Rate Module Statistics 95% CLC (ECMA/metro) [5235. 97, 5365. 93] Resistance Module: In the final part of this lab, resistors were to be measured in batches from each of the group members. This section of the lab showed the most precision with the least error. From the color coded bands on the ten resistors, it was concluded that the value of the resistors was 470 sq. All of the results in table old. Show that the resistors were only reading 400 sq. All 60 recorded measurements were close to 400 ink which could be from mislabel resistors. The pooled mean of the three samples does fall within the 90% and 95% confidence intervals even with including some outliers in the data. The full experimental data can be found in Table C in the Appendix. Sample Mean (Q) 400. 033 99% (Q) 1. 588 [399. 02, 401. 05] Table old. Resistance Module Statistics 95% CLC (sq) [399. 29, 400. 78] Conclusion: This laboratory focused on repeatability measurements, batch measurements, and statistical concepts/ principles to analyze the collected data. This was achieved through the use of a caliper, stopwatch, and a digital multi-meter for measurement purposes. Using these tools, the group is able to measure length, flow rate, and resistance. The statistical concepts used in this lab were sample mean, standard deviation, true mean, and the range and level of confidence. The results of the linear dimension module prove that there is always going to be a small amount of human error when using devices such as a manual caliper. That error is relatively larger when trying to sum two measurements as compared to measuring a total length . The measurement of the bolt as a whole has a narrower CIA and true mean range of [2. 265, 2. 267]. The 7 standard deviation for total length (A) [0. 0033 in. ] supports the theory that measuring the entire length at once is more accurate than summing the cap thickness (B) and bolt length (C) together, which is evident by analyzing the standard deviation of (B+C) [0. 0268 in. ]. The results of the flow rate module show that there is significantly far more human error when trying to measure the time it takes for water o fill a beaker. This can be attributed to response time of starting/stopping the stopwatch. The standard deviation [138. 835 /min] seems high, but calculations show that the sample mean [5300. 5 /min] falls within the true mean range for CLC [5247. 27, 5354. 63 /metro] and also for 95% CLC [5235. 97, 5365. 93 /min]. The results of the resistance module indicated a difference between the sample mean [400. 033 sq] of the batch measurements and the supposed value of the resistors [470 sq] according to the color coded bands. This was the most precise module with a standar d deviation of [1. 588 sq] and all the pooled means fall within he 95% CLC with a true mean range of [399. 29, 400. 78 sq], and the 99% CLC with a range of [399. 02, 401. 05 sq]. This laboratory experiment allowed the group to differentiate between repeatability measurements and batch measurements and apply the statistical theories learned in lecture to analyze the collected data. To minimize error percentage, calibrating the caliper before each measurement might be advantageous. Another advantage might be making markings on the bolt where each member of the group takes measurements instead of at random/different spots each time. How to cite Lab report, Papers

Report On Alexander The Great Essay Example For Students

Report On Alexander The Great Essay Alexander the Great was one of the greatest rulers and conquerors of all time. He conquered the mighty Persian Empire and most of the known world at that time. Alexander was born in Pella, the ancient capital of Macedonia. He was the son of an excellent general and organizer, named Philip II King of Macedon. His mother was Olympias, princess of Epirus. She was brilliant and hot-tempered. Alexander inherited the best qualities of both his parents. But he was even more ambitious than his father. He wept bitterly when he heard of Philips conquests and said, My father will get ahead of me in everything, and will leave nothing great for me to do. Alexanders mother taught him that Achilles was his ancestor, and that his father was descended from Hercules. Alexander learned by heart the Iliad, a story about the deeds of Achilles. He carried a copy of the Iliad with him, and Achilles became Alexanders hero. Even as a boy Alexander was fearless and strong. He tamed the beautiful and spirited Bucephalus, a horse that no one else dared to touch or ride. Later, this famous steed carried him as far as India, where it died. Alexander then built the city of Bucephalus on the Hyphasis River in memory of his beloved horse. Philip was so proud of Alexanders power over the horse that he said, ;O my son, seek out a kingdom worthy of thyself, for Macedonia is too little for thee. ; Philip and Olympias saw the potential for greatness in the boy and arranged for his education. His first teacher was the harsh Leonidas, a relative of Olympias, perhaps her uncle. Leonidas was a strict disciplinarian who instilled in Alexander his ascetic nature. This nature became famous during his Persian and Indian expeditions, where he would live simply, very much like his troops. Leonidas was replaced with Lysimachus, who curried the favor of the king by calling him Peleus, Alexander Achilles, and himself Phoinix, the name of Achilles tutor. Lysimachus taught Alexander to play the lyre, and taught him an appreciation for the fin e arts of music, poetry, and drama. Philip and Olympias wanted nothing less than the best for their son, so when he was 13, his parents hired Aristotle from Athens to be his personal tutor. The two of them spent time at Mieza, a temple about 20 miles from the palace at Pella. Under Aristotle, Alexander learned philosophy, ethics, politics, and healing. Aristotle inspired the talented youth with a great love for literature. He took part in sports and daily exercise to develop a strong body. Aristotle also inspired in Alexander a keen interest in other countries and races of people, and in animals and plants. Alexanders education was not all from books. He talked with ambassadors from many foreign countries, and with other noted persons at his fathers court. When he was only 18, he commanded part of Philips cavalry at the battle of Chaeronea. Alexander also acted as his fathers ambassador to Athens. In 336 B.C. Phillip II was assassinated, and at the age of twenty Alex ascended to the Macedonian throne. As soon as he received that position he found that there were many people plotting against him. So he disposed of the conspirators quickly by execution. Then he descended on Thessaly and restored Macedonian rule. Before the end of the year 336 Alex reestablished his position in Greece. He was also elected to the congress of states at Corinth. In 335 as general of the Greeks he carried out a successful campaign against the Persians, penetrating to the Danube River. On the way back Alex crushed the Illyrians in a single week. On his way back Alex learned that the people in the city of Thebes revolted and called upon the people of Athens to join them. Alexander soon appeared before Thebes with his army and Alex took over the city, destroyed everything except for the temples of the gods and the house of Pindar, a Greek lyric poet. The surviving inhabitants who numbered around eight thousand were sold into slavery. With this siege over Thebes all of the other Greek states went in to submission .

US Economy Essays - Economy Of Asia, Oregon, Pacific Northwest

US Economy The U.S. economy has been slowly growing since the spring of 1991, growth increased in 1997 when real gross domestic product rose 3.9 percent from an increase of 2.8 percent in 1996. At the same time inflation in 1997 fell to 2.3 percent decreasing the cost of living. Payroll jobs rose from 121.14 million in January to 124.29 million in December and the national unemployment rate declined over the year by .7%. This combination of events was good news for the businesses and the general public because it increased wealth and lowered prices. On July 2,1997 Thailand started a crisis in Asia which effected U.S. exports to the region. U.S. exports to Asia represent 30% of total exports but were cut in half to 13.4% in 1997. The interest declines offset some of the drag on the American economy from the reduced exports by concentration on construction and real estate. Asia crisis was a threat to the U.S. economy but a strong dollar and the reduced commodity demand helped to keep the low inflation period. In 1998 the economy experienced further acceleration growth, unemployment decreased faster to lows not seen in 20 years and the price index stayed the same. Falling interest rates and oil prices encouraged consumers. Economists still kept a close eye on the unfolding events in Asia. In 1999 U.S. economy will slow due to weak markets around the world consumer spending will decrease and businesses will slow down their investing. Although inflation has not changed the decline in oil prices and the rising dollar will fade. Nations GDP is excepted to slow growth near 2% and the world economy possibly will stabilize. Oregon's Economy Just like the rest of the county Oregon has been booming since early 90's but came to a moderate pace in 1997. Oregon only experienced dramatic declines in lumber and wood products production and employment. In 1997 turmoil in Asia started which brought concern to the state due to its great exports to that region. Nike experienced lost sales in Asia and laid of workers in Oregon. Other big companies like Intel, Mitsubishi Silicon, Hewlett Packard, Tektronix, and Sequent saw weakened sales and reduced employment. The number of people moving to Oregon declined and request for residential construction permits were down 2.9%. Oregon's overall tax burden has declined with capped property taxes and rapid increases in personal income. In1999 economy will continue to grow but increments will diminish. Employment growth in 1998 was 2.4% and will fall in 1999 to 1.5%. Oregon and the Western Region Oregon along with Idaho and Utah experienced a decline in the total amount of people coming to their state. In the region all states saw job gains that were above the national average. Nevada, Idaho, California, Washington saw the fastest growth while Oregon and Utah eased. Employment in services the region did better when the nation except in Nevada, Utah and Oregon which slowed down from 1996. Only mining, military, and agricultural sectors saw earnings growth below the national figures in Oregon. Dividends, interest, and rental income rose above the national average of 4.3% in all the states while transfer payments rose more slowly than the nation in Oregon, Washington, and California. Residential permits declined in Nevada, Oregon, Utah, and Idaho but increased by 15.3 % in the "Northern 34" and 4 % increase in Washington. The Asian crisis has not effected other states in the region as much as Oregon that's why it is experiencing some economy growth difficulties.

Discussion 4 Essay Example | Topics and Well Written Essays - 500 words

Discussion 4 - Essay Example He established a new social hierarchy system. This was different from what prevailed in the time of his predecessors. His new social hierarchy was based on talent and he himself chose the most able generals, scientists, wealthy men and former nobles as senators. He also introduced a new system of hierarchy of noble titles. These titles could be inherited but they had also had to be supported with wealth. Able and favored generals were often rewarded with estates in conquered territories. He also appointed his sons to exotic positions. His most impressive and long last achievement was the introduction of Civil Code also called Napoleonic Code that was completed in 1804. Under the code property rights, religious freedom and uniform laws of Freedom provided equal treatment for adult males but reduced the rights of women, children and employees. On the battle ground, he went way beyond his predecessors. He did not imply that war, the leader must memorize all the details of past wars and emulate the completely, for instance those fought by Alexander, Hannibal, Ceasar, Turenne, and Frederick the Great. Napoleon was not a greater innovator as a soldier himself. Infact, he did not trust ideas, precisely why he disbanded the balloon companies inherited from the Armies of the Revolution and rejected Rover Fulton’s offer of submarines and naval mines.

Buddhist Scriptures Essay Example | Topics and Well Written Essays - 500 words

Buddhist Scriptures - Essay Example Buddha expects everyone to live and lead a happy and peaceful life. Buddhism does not entertain strange, unfounded beliefs and is not much concerned about what is happening over the sky. It addresses to the day to day secular problems and the procedures to meet the challenges with equanimity, and with a confident mental poise. Buddha is an enlightened soul, and he has transcended the barriers of the mind and he remains in the state of bliss. His revelations (not teachings) are delivered from the conflict-free zone, and hence they are divine-ordained, blemish-free and everlasting. He does not expect his followers to act on blind faith, and advises them to put the individual experiences to test and find out the truth with own efforts. When he says that there are many Buddhas before me and there will be many Buddhas after me and each one of you have the intrinsic capacity to become Buddha, he means that the path of self-realization is possible with one’s individual efforts only. There are no shortcuts to attain that divine state, and get freedom from dualities. Buddhism prescribes twin goals for an individual. They are, to know self and to learn the teachings of Buddha. The ordinary nature of an individual relates to the gross traits like anger, fear, jealously and other negative feelings. The other is the true nature (the divine one) that is wise, pure and perfect. That is the state of bliss and in terms of Buddhism it is called Buddha nature. The difference between the two natures is the former is the non-awakened state and the latter is the awakened state. In the Buddhist scriptures, one will find elaborate commentaries on profound topics and universal truths like, nothing is lost in the universe, everyt hing changes, law of cause and effect, the four noble truths, etc. When one reads the variety of Buddhist Scriptures, they apparently appear full of contradictions but their essence is the same. Their perplexity is

Rare Earth Doped Upconverting Nanoparticles

Rare Earth Doped Upconverting Nanoparticles Rare Earth Doped Upconverting Nanoparticles: Synthesis and Application in Bio-Imaging Nidhi Malviya1, Vinita Rajput Chouhan1, Sudeshna Ray2 ABSTRACT Upconversion luminescence, a nonlinear process, which re-emits a photon at a shorter wavelength by the absorption of more than one photon, successively at longer wavelengths via long-lived intermediate energy states, is useful for important applications in various fields like fluorescence bio-imaging and lasers. This NIR-to-NIR up-conversion process provides deeper light penetration into biologicalspecimen and results in high contrast optical imaging due to absence of an auto fluorescence background and decreased light scattering. Excitation at long wavelengths also minimizes damage to biological materials. Herein, we report the different mechanisms responsible for the Upconversion process of rare-earth (Er3+, Ho3+, Tm3+) doped nanoparticle and methods that are used to synthesize and decorate up converting nanoparticle. I INTRODUCTION Upconversion is an optical process that involves the conversion of lower-energy photons into higher-energy photons. It has been extensively studied since mid-1960s and widely applied in optical devices. Over the past decade, high-quality rare earth-doped Upconversion Nanoparticles have been successfully synthesized with the rapid development of nanotechnology and are becoming more prominent in biological sciences. The main difference between Upconversion Nanoparticles and other nonmaterial’s is that they can emit visible light under near infrared irradiation. Upconversion nanoparticle (UCNPs), particularly lanthanide-doped nanocrystals, which emit high energy photons under excitation by the near-infrared (NIR) light, have found potential applications in many fields, including biomedicine and is found improved tissue penetration and higher photochemical stability as compared with traditional down-conversion fluorescence imaging. The unique Upconversion process of UCNPs may be u tilized to activate photosensitive therapeutic agents for applications in cancer treatment. Upconversion luminescence imaging in vivo is expected to be the next generation photoluminescence imaging technique since it provides high sensitivity and spatial resolution. Due to their multicolour emission, high brightness and long lifetime, lanthanide ions based luminescent nonmaterial have tremendous promise as indicators and photon sources for numerous application such as boilable, light-emitting devices, sensor technology, and low-threshold lasers. So it is very important to successfully prepare the rare-earth doped inorganic nanocrystals with good dispensability in organic solvents. The Up conversion phenomenon has been transition metals, actinides, but mainly in the rare earth elements, which contain the lanthanide (Ln) series, Yttrium, and scandium. Ln3+ ions heave special 4fn 5d0-1inner shell configurations that are well – shielded by outer shell and have unique energy level structures. These Ln3+ ions can exhibit sharp luminescence emission via intra-4f or 4f-5d transitions. Their luminescence properties, as narrow bandwidth, long-time emission, and anti-stokes emission, have been widely applied in lasers, solar cell, analytical sensors, optical imaging, and photodynamic therapy. Most fluorescent materials, including dye molecules, quantum dots, and dye-doped silica/gold nanomaterials, emit light by the down conversion process (emitting lower-energy photons under higher-energy irradiation). Although the uses of a conventional organic dye molecule or quantum dot (QD) based biomarker have achieved significant progress in real-time detection and bio imaging, they still have drawbacks. These fluorescent materials are generally excited by ultraviolet (UV) or visible light, which may induce auto fluorescence and photo damage to biological samples, resulting in low signal-to-noise ratio and limited sensitivity. These limitations prompted the development of a new type of high-quality and well-shaped nonmaterial’s known as up conversion nonmaterial’s (UCNs [1-7]. Lanthanide-doped Upconversion (UC) nanophosphors are promising optical contrast agents for biomedical applications due to their photo stability, sharp emission peaks, and long emission lifetime [8, 9]. Upon near infrared (NIR) excitation, UC nanoparticle exhibit intense visible emission via multiphoton processes involving the lanthanide ions within them [10-12]. For in vitro or in vivo imaging, the use of NIR excitation minimizes absorbance, scattering, and fluorescence from cells and tissues, allowing imaging against a dark background [13]. In contrast, commercially available labels, such as organic dyes and quantum dots, typically must be imaged against a background of Stokes-shifted tissue autofluorescence induced by UV, blue, or green excitation[14]. In addition, because of the existence of real intermediate energy levels in lanthanide ions, this Upconversion process can be much more efficient than in conventional multiphoton-absorption-induced fluorescence of organic dyes or qua ntum dots, where the intermediate levels are virtual. Bio-imaging is a term that covers the complex chain of acquiring, processing and visualizing structural or functional images of living objects or systems, including extraction and processing of image-related information. II MOTIVATION OF MY WORK Lanthanide-doped upconversion-luminescent nanoparticles (UCNPs), which can be excited by near-infrared (NIR) laser irradiation to emit multiplex light, have been proven to be very useful for in vitro and in vivo molecular imaging studies. In comparison with the conventionally used down-conversion fluorescence imaging strategies, the NIR light excited luminescence of UCNPs displays high photostability, low cytotoxicity, little background auto-fluorescence, which allows for deep tissue penetration, making them attractive as contrast agents for biomedical imaging applications. In this review, we will mainly focus on the latest development of a new type of lanthanide-doped UCNP material and its main applications for in vitro and in vivo molecular imaging and we will also discuss the challenges and future perspectives. New materials with high Biocompatibility and more intense emission spectra are needed to be developed so for deep tissue imaging. III CONCLUSION The past decade a large number of scientists have investigated the potential application of UCNPs in bioimaging. Lim et al. firstly reported the use of UCNPs as in vivo Caenorhabditis elegans imaging agent. Along with the fast developement of UCNPs for biological applications. UCNPs have also been applied contrasts agents in positron emission tomography (PET), magnetic resonance imaging (MRI), X-ray computer tomography (CT) for in vitro and in vivo multimodal imaging. Futhermore, UCNPs could also be combined with anti-cancer drugs, photosensitizers or gold nanostructures for potential therapeutic application. Up to now, a variety of Upconversion nanophosphors have been developed for bioimaging, and most of them are based on rare earth doped NaYF4. Other kinds of RE doped nanoparticles, such as NaGdF4, NaLaF4, Y2O3, GdF3, CeO2, LiNaF4, Ca3(PO4)2, ZrO2 and GdOF etc. have al so been considered as excellent UCNPs in recent years due to their strong Upconversion luminescence intensity an d good photostability.

Reliving a Memory through a Successful Narration Essay

People weave hundreds of stories throughout the course of their lives. Most of them are experiences that brought fear, embarrassment or changes in their lives. More often than not, these stories are shared with other people in one way or another. Telling a story can be done through several ways. You can re-enact the scenario to tell a story. You can utter words that describe the incident or you simply can put words into writing to form a narration. Before you put your story into writing, there are two things that need to be done: visualizing and planning. Prior to writing your narration, you should visualize the story. You yourself should be able to relive the scene in your mind to help you in coming up with the right words to describe the scenario. Then, you should plan on how you going about your story. Each part of your story is preceded by another. You should be able to prepare on how you would relate the previous scenario to the current one. Once you have visualized and planned for your narration, you are now ready to put your story into writing. Writing a narration involves a series of steps that could help the writer create a vivid picture of his experiences in life. Only when the reader is able to form clear mental images of each scenario can the narration be considered successful. The first step involves choosing the important details. You should only emphasize on important points of your story. Minor details should simply be de-emphasized or removed entirely. If you are telling about the time you won the lottery, then you should not dwell into details about the dinner you had before find out your win. You should only give emphasis on your initial reaction, on the reaction of the people around you, and on how you planned to spend your winnings. The use of a chronological order comprises the next step. Oftentimes, the best stories are told in the order in which they occur. This order helps the reader better understand the story as it unfolds. Centering on conflict is what the third step tells the writer to do in order to weave a successful narrative. These conflicts may either deal with inner dilemmas or with another person. It may also include conflicts with an impersonal outside force. In each story revolving around a conflict, the resolution of the conflict marks the end of the story. Showing the reader what happened is the fourth step. It is usually better to give the readers a visualization of the significant moments in the narration rather than telling the story. You can do so by using a detailed description of the event and each character participating in that even. However, using a dialogue has the strongest effect on the reader that it does not only make the reader see what is happening. It also makes the reader feel the emotions in the story. The next step involves making a point. It is simply important to have a point that would rationalize the existence of your story. You should present your point using a sentence. Telling a story can be done in various forms. However, one of the most common forms involves writing. Putting your story into writing is simple however making it a successful narration entails extra work. In order come up with a vivid picture of your story, there are steps which could be followed to ensure that the reader do not only see but also feel the emotions in the story.

Impact of Christianity on Philosophy Essay

Introduction Christianity’s doctrines and tenets draw from a rich heritage of long historical development. And since it is a religion shaped by history, it follows only that its teachings are influenced by the prevailing philosophies within it. But there are also good reasons to think that, conversely, Christianity is a religion that did not only draw from existing philosophies in history but also generated a significant impact on them. Three reasons may be cited to support this contention. First, philosophy was made popular by the rise of Christianity; second, key Christian thinkers have endeavored to incorporate philosophy within their belief-systems; and third, many of their teachings are actually philosophical issues Christianized in the process. Christianity and Philosophy   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   First, the rise of Christianity seems to be a factor responsible for the great interest many people have shown towards philosophy during the ancient times. It must be noted that even before Christianity as a religious movement was to be commenced (following the death of Jesus, and the rapid conversion to a belief in him), prevailing philosophies such as Epicureanism, Neo-Platonism, Stoicism, and Skepticism were already in place (Moore & Bruder, 2005, p. 77). But since the Romans – the political power of that time – showed little or no interest to these philosophies, they remained largely an undercurrent phenomenon. In many ways, the rise of Christianity paved the way for such philosophies to become widespread, as they are (specifically, Neo-Platonism and Aristotleanism) employed in many â€Å"religious ideas and practices† (p. 78).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Second, key thinkers such as Augustine and Thomas Aquinas also contributed a lot in employing philosophy as a way to explicate Christian beliefs. With Augustine, â€Å"Christianity became so permanently interwoven with elements of Platonic thought† (Moore & Bruder, 2005, 79). Augustine’s theology was chiefly concerned with arguing truths about the eternality of Christian God and the capacity of the mind to grasp the eternal truths; and these teachings are importations of the Platonic metaphysics and cosmology. Aquinas meanwhile was responsible conceiving the â€Å"underlying accord between Christian principles and Aristotle’s philosophy† from the ashes of the dark ages (p. 88). As with Plato, Aquinas’ teachings about God, nature and existence, knowledge and the world conveniently employed the methods used by philosophy.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Third, many teachings forwarded by key Christian thinkers are actually philosophies which underwent a process of Christian adaptation. In other words, the manner by which these thinkers employed philosophy in explicating their theologies â€Å"in effect† may be regarded as a process of â€Å"grafting the principles and distinction† of Greek philosophy to â€Å"Christian revealed truth† (p. 88) The doctrine of the human soul and the Trinity are glaring examples to this. If only to argue, the Christian teaching that human persons have both body and souls is very reminiscent of the Platonic dualistic cosmology, i.e., that reality is composed of matter and form. The doctrine of the Trinity meanwhile is heavily employing the concepts of universals – a teaching that enables one to infer the conceptual similarities defining of two otherwise distinct entities. The result of this adaptation process is very significant to philosophy. What this process achieved was to ultimately create a â€Å"complete Christian philosophy† (p. 89). Conclusion   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   This paper concludes that indeed, Christianity is a religious movement that had a significant impact in the development of philosophy. While there are many reasons that could be cited to substantiate such a claim, three factors were deemed to be of paramount importance: namely, the rapid rise of Christianity during the ancient era, the use of prevailing philosophies to explain Christian tenets by key Christian thinkers, and the creation of a complete Christian philosophy which capitalized on adapting philosophical issues within the context of Christianity.

It is extremely important that Sleep Apnea is emphasized so that more people are aware of it. Introduction: â€Å"The National Sleep Foundation† says that a lot of people don’t know what sleep apnea is. Sleep Apnea is a dangerous disease that can lead to death while you’re sleeping. Body: I. There are two types of Sleep Apnea A. Central Sleep Apnea 1. Unlike OSA, the airway is not blocked, but the brain fails to signal†¦show more content†¦D. You’re overweight. The extra soft fat tissue can thicken the wall of the windpipe. This narrows the inside of the windpipe, which makes it harder to keep open. E. The aging process limits your brain signals’ ability to keep your throat muscles stiff during sleep. Thus, airway is more likely to narrow or collapse. Transition: â€Å"National Institute of Health† has Steps on how to treat Sleep Apnea. IV. â€Å"The National Institute of Health† suggests that Sleep Apnea should be treated with lifestyle changes, mouthpieces, breathing devices, and surgery. Goals of treating sleep apnea are to restore regular breathing during sleep and relieve symptoms such as loud snoring and daytime sleepiness. A. Lifestyle Changes 1. Avoid Alcohol and medicines that make you sleepy. 2. Losing weight if you’re overweight or obese. 3. Sleeping on your side instead of your back to help keep your throat open. 4. Keeping your nasal passages open at night with nasal sprays or allergy medicines, if needed. 5. If you smoke, quit. B. Mouthpieces 1. Oral Appliance C. Breathing Devices 1. Cpap Machine D. Surgery Conclusion: Learning that Sleep Apnea is a dangerous disease and more people are being diagnosed with it. I hope that learning more about this disease more people will be more aware of it.
