Margaret Knight - Queen of Paper Bags

Margaret Knight - Queen of Paper Bags Margaret Knight was an employee in a paper bag factory when she invented a new machine part that would automatically fold and glue paper bags to create square bottoms for paper bags. Paper bags had been more like envelopes before. Workmen reportedly refused her advice when first installing the equipment because they mistakenly thought, what does a woman know about machines? Knight can be considered the mother of the grocery bag, she founded the Eastern Paper Bag Company in 1870.   Earlier Years Margaret Knight was born in York, Maine, in 1838 to James Knight and Hannah Teal. She received her first patent at the age of 30, but inventing was always part of her life. Margaret or ‘Mattie’ as she was called in her childhood, made sleds and kites for her brothers while growing up in Maine.  James Knight died when Margaret was a little girl. Knight went to school until she was 12, and began working in a cotton mill. During that first year, she observed an accident at a textile mill. She  had an idea for a stop-motion device that could be used in textile mills to shut down machinery, preventing workers from being injured.  By the time she was a teenager the invention was being used in the mills. After the Civil war, Knight began working in a Massachusetts paper bag plant. While working in the plant, she thought how much easier it would be to pack items in paper bags if the bottoms were flat. That idea inspired Knight to create the machine that would transform her into a famous woman inventor. Knights machine automatically folded and glued paper-bag bottoms – creating the flat-bottom paper bags that are still used to this very day in most grocery stores. Court Battle A man named Charles Annan tried to steal Knights idea and receive credit for the patent. Knight did not give in and instead took Annan to court. While Annan argued simply that a woman could never design such an innovative machine, Knight displayed actual evidence that the invention indeed belonged to her. As a result, Margaret Knight received her patent in 1871. Other Patents Knight is considered one of the female Edison, and received some 26 patents for such diverse items as a window frame and sash, machinery for cutting shoe soles, and improvements to internal combustion engines.   A few of Knights other inventions: Dress and skirt shield - 1883Clasp for robes - 1884Spit - 1885Numbering machine - 1894Window frame and sash - 1894Rotary engine - 1902 Knights original bag-making machine is in the  Smithsonian Museum  in  Washington,  D.C. She never married and died on October 12,  1914,  at the age of 76. Knight was inducted in the  National Inventors Hall of Fame  in 2006.

Overview of the Last Glaciation

Overview of the Last Glaciation When did the last Ice Age occur? The worlds most recent glacial period began about 110,000 years ago and ended around 12,500 years ago. The maximum extent of this glacial period was the Last Glacial Maximum (LGM) and it occurred around 20,000 years ago. Although the Pleistocene Epoch experienced many cycles of glacials and interglacials (the warmer periods between the colder glacial climates), the last glacial period is the most heavily studied and best-known portion of the worlds current ice age, especially with regard to North America and northern Europe. The Geography of the Last Glacial Period At the time of the LGM (map of glaciation), approximately 10 million square miles (~ 26 million square kilometers) of the earth was covered by ice. During this time, Iceland was completely covered as was much of the area south of it as far as the British Isles. In addition, northern Europe was covered as far south as Germany and Poland. In North America, all of Canada and portions of the United States were covered by ice sheets as far south as the Missouri and Ohio Rivers. The Southern Hemisphere experienced the glaciation with the Patagonian Ice Sheet that covered Chile and much of Argentina and Africa and portions of the Middle East and Southeast Asia experienced significant mountain glaciation. Because the ice sheets and mountain glaciers covered so much of the world, local names have been given to the various glaciations around the  world. The Pinedale or Fraser in the North American Rocky Mountains, Greenland, the Devensian in the British Isles, the Weichsel in Northern Europe and Scandinavia, and the Antarctic glaciations are some of the names given to such areas. Wisconsin in North America is one of the more famous and well-studied, as is the Wà ¼rm glaciation of the European Alps. Glacial Climate and Sea Level The North American and European ice sheets of the last glaciation began forming after a prolonged cold stage with increased precipitation (mostly snow in this case) took place. Once the ice sheets began forming, the cold landscape altered typical weather patterns by creating their own air masses. The new weather patterns that developed reinforced the initial weather that created them, plunging the various areas into a cold glacial period. The warmer portions of the globe also experienced a change in climate due to glaciation in that most of them became cooler but drier. For example, rainforest cover in West Africa was reduced and replaced by tropical grasslands because of a lack of rain. At the same time, most of the worlds deserts expanded as they became drier. The American Southwest, Afghanistan, and Iran are exceptions to this rule however as they became wetter once a shift in their airflow patterns took place. Finally, as the last glacial period progressed leading up to the LGM, sea levels worldwide dropped as water became stored in the ice sheets covering the world’s continents. Sea levels went down about 164 feet (50 meters) in 1,000 years. These levels then stayed relatively constant until the ice sheets began to melt toward the end of the glacial period. Flora and Fauna During the last glaciation, shifts in climate altered the world’s vegetation patterns from what they had been prior to the formation of the ice sheets. However, the types of vegetation present during the glaciation are similar to those found today. Many such trees, mosses, flowering plants, insects, birds, shelled mollusks, and mammals are examples. Some mammals also went extinct around the world during this time but it is clear that they did live during the last glacial period. Mammoths, mastodons, long-horned bison, saber-toothed cats, and giant ground sloths are among these. Human history also began in the Pleistocene and we were heavily impacted by the last glaciation. Most importantly, the drop in sea level aided in our movement from Asia into North America as the landmass connecting the two areas in Alaskas Bering Strait (Beringia) surfaced to act as a bridge between the areas. Todays Remnants of the Last Glaciation Though the last glaciation ended about 12,500 years ago, remnants of this climatic episode are common around the world today. For example, increased precipitation in North Americas Great Basin area created enormous lakes (map of lakes) in a normally dry area. Lake Bonneville was one and once covered most of what is today Utah.​ The  Great Salt Lake is todays largest remaining portion of Lake Bonneville but the old shorelines of the lake can be seen on the mountains around Salt Lake City. Various landforms also exist around the world because of the enormous power of moving glaciers and ice sheets. In Canadas Manitoba for instance, numerous small lakes dot the landscape. These were formed as the moving ice sheet gouged out the land beneath it. Over time, the depressions formed filled with water creating kettle lakes. Finally, there are many glaciers still present around the world today and they are some of the most famous remnants of the last glaciation. Most ice today is located in Antarctica and Greenland but some ice is also found in Canada, Alaska, California, Asia, and New Zealand. Most impressively though are the glaciers still found in the equatorial regions like South Americas Andes Mountains and Mount Kilimanjaro in Africa. Most of the worlds glaciers are famous today however for their significant retreats in recent years. Such a retreat represents a new shift in the earth’s climate- something that has happened time and time again over the earths 4.6 billion year history and will no doubt continue to do in the future.

Introduction to Business Law - Essay Example Law of misrepresentation have provisions that offer redress of the consumer detriment (Cartwright, 2007). However, the rights appear in fragmented forms that are complex hence making it unclear. The complexities presented by the law require amendments to ensure effective application of the law. The current laws provide confusions to the advisers of the consumers and traders as well as their clients, a fact that pose hindrances to private ordering. Therefore, the essay presents the law by highlighting the gaps that need amendments by considering possible avenues that are applicable in a case where the consumer is mislead by the trader. Misrepresentation refers to misleading actions when considered from a private law perspective. However, this law does not occur in a single body but rather represents several causes of actions for a number of issues arising from misrepresentation (Law Commissions, 2010; Atiyah and Treitel, 1967). Therefore, it gives rise to several families of rule. When a consumer intends to bring forth claims of misrepresentation, they are required to go through sea of actions that may be intimidating and lead to uncertain actions (Law Commissions, 2010). These represent some of the discouragement that hinders the consumers from commencing any claim from the fraudulent traders. When a consumer is presented with misleading facts, or is told something that is untrue, such a consumer is said to have been mislead. When the trader breaches the contract or act in a fraudulent manner, the law of England governs this in the 1967 act of the misrepresentation (Warren, 1983). A misrepresentation depends on whether the information falls within the three categories of factual, falseness and not an omission (Cartwright, 2007). When a representation is untrue, it represents an actionable prospect. However, when it is untimely, unintelligible, or not

Western Cultures. Loss Of Centerdness In The Early 20th Century Essay

Western Cultures. Loss Of Centerdness In The Early 20th Century - Essay Example The political power exerted by the colonizer made it easy for them to establish that they were culturally superior as well. The establishment of the cultural superiority of the colonizer has been a step by stem process by which first of all, the colonizer’s culture is imposed, then the culture of the colonized is replaced with a new culture that is still inferior to, but imitative of the colonizer’s culture. The result of this phenomenon is that slowly the colonized cultures and people belonging to them loose their self-esteem and abandon their culture out of an inferiority complex. The tragedy of this situation is that even when colonization ends, this sense of inferiority of one’s own culture will remain for a long time in the minds of the colonized. Introduction Culture is a phenomenon that embeds all human being, gives meaning and purpose to their lives and provides them a sense of belonging and connection. Once culture is disintegrated, a whole society can a lso get disintegrated. In the history of humanity, nothing else than colonialism had made such an impact on specific cultures as to disintegrate them partially or completely. As the colonizers were mostly the westerners and the colonized being the non-western cultures, the result was an imposition of the cultural hegemony of all western values. The non-western cultures faced a complex identity crisis in the face of this cultural invasion. In the later nineteenth and early twentieth century, colonialism emerged as an extension of western political and cultural imperialism, to such an extent that â€Å"the self-proclaimed â€Å"superiority† of â€Å"Western culture†, functioned as the rationale and mandate for colonialism† (Narayan and Harding, 2000, p.83). The result was that whichever cultures colonized by the western world, began to feel themselves as inferior cultures to the western culture and lost their sense of centeredness. For example, David (2011) has in vestigated the colonial experience of Philippines and showed that the Americans settled in Philippines as part of the colonial legacy, still view Filipino culture as inferior to western and American culture (p.13). Sonnenburg (2003) has pointed to how the British colonization of Australia treated the indigenous people of Australia as some animal or cattle and forcefully separated children belonging to these aborigines from their mothers, â€Å"a practice that continued into the mid-twentieth century† (p.1). Similarly, the English colonial experience in Ireland resulted in the Anglicization of Ireland and suppression of Irish language and culture (Sonnenburg, 2003, p.280). All the colonized cultures had experienced this kind of cultural oppression and this experience was described as, â€Å"loss of centeredness,† by many scholars (Kebede, 2004;Sayre, 2012). What is meant by this expression is that the colonized cultures that were self-reliant and centered around their o wn culture were forced to feel that their cultures were no more the center of the universe they knew. Instead they began to feel that their cultures were inferior to the cultures that colonized them. The most serious consequence of this loss of centeredness has been that even after the colonial rule was withdrawn, the people continue to experience this loss of centerednedd (Kebede, 2004). Rightfully calling colonialism, â€Å"a cultural project of control†, Dirk (1992) has described the complex experience of colonialism from the point of view of culture (p.7). He (Dirk, 1992) has tried to describe this complexity by saying that â€Å"not only did colonial rulers align themselves with the universal and inexorable forces of science, progress, rationality and modernity, they displaced many of the disruptions and excesses of rule

Time Value of Money Essay Example for Free

Time Value of Money Essay Time value of money is useful in making informed business decisions. For example the net present value method can be used to help decide the best alternative among multiple alternative uses of a firm or personal financial resources. By discounting various alternatives to their present value one can compare the alternatives. Time value of money can also answer such questions as what ones investment will be worth at a certain point of time in the future, assuming a certain interest rate. Time value of money can also be used to compute such useful information as car, mortgage and other loan payments. Another use of time value of money in accounting is reporting of certain long-term assets and liabilities. Time value of money is based on the principle of compound interest. Each time there is a compounding period the new principal is increased by the interest from the previous period. Converting Before Using the Tables When using the tables, you may need to convert if, for example, in a lump sum situation there are more than one compounding periods in a year. Or you may need to convert (to monthly compounding) if, for example, you are working with an annuity situation involving a car loan that involves monthly rather than annual periodic payments. You often need to convert whether it is a lump sum or an annuity situation. Do the following conversions before using the tables. See some of the examples which follow these notes. For semi-annual compounding [or for deposits every six months in an annuity], take the annual interest rate and divide it by 2. Take the number of years and multiply by 2. For quarterly compounding [or for quarterly deposits in an annuity] take the annual interest rate and divide it by 4. Take the number of years and multiply by 4. For monthly compounding [or for monthly deposits in an annuity] take the annual interest rate and divide it by 12. Take the number of years and multiply by 12. Lump Sum Amounts Future Value of $1 = Present Value X Future Value of $1 Table Factor Present Value of $1= Future Value X Present Value of $1 Table Factor Use the $1 table when you are dealing only with a lump sum amount. (However when you have an annuity in the problem, do not use the lump sum table; instead use the annuity table. Use the annuity table even if you are looking for a lump sum, as shown in No. 4 which follows these notes.) Notice that there are four variables with lump sum situations: Present Value, Future Value, Interest Rate, and Period. You need to know three out of the four to figure out an unknown. You saw above how to compute Present Value and Future Value. Now suppose you want to find the interest rate. Present Value Approach: PV / FV = computed PV Table factor Go to the PV table. Where the table factor and periods intersect is the interest rate. Use this same approach to figure the number of periods when you know the interest rate and PV and FV. Annuities An annuity means a series of equal periodic deposits, or rents which can be either payments or receipts; they are made at equal periodic intervals. Use the annuity tables when you are dealing with equal periodic payments or receipts at equal periodic intervals. Use Ordinary Annuity table for payments made at the end of the period. Use Annuity Due table for payments made at the beginning of the period. Future Value of an Annuity = Annuity Deposit X Future Amount of an Annuity Table factor. Present Value of an Annuity = Annuity Deposit X PV of Annuity Table Factor Note the Annuity Deposit may be either a payment or receipt. Now say you wish to find the amount of the deposit, which could be either a periodic payment like a car or mortgage payment, or a periodic receipt such winnings from the lottery or more realistically monthly withdrawls of cash during retirement. Rent or Payment/Receipt = PV / PV of annuity table factor or Rent or Payment/Receipt = FV / FV of annuity table factor You cannot just use either of the PV or FV approaches. Use the PV approach if PV is the given information. You would have to use the FV approach if FV is the given information. Often you use the present value approach though. For example if you are buying a car and want to figure out the car payments, the current price of the car is Present Value. It is assumed to be the cash-equivalent price. A Few Practice Problems 1. You want to know how much you should deposit in the bank each month in order to have $10,000 in four years. What type of problem is this? A. present value of an annuity B. present value of an amount C. future value of an annuity D. future value of an amount The correct answer is C. First you know this is an annuity because it involves equal periodic payments to the bank at equal intervals. You know it is future value because you are asked to find what future amount your annuity will grow to. Even though it is growing to a single amount, be sure to note that you are looking for the future value of an ANNUITY. 2. You want to know how much you should deposit in the bank now in order to have $10,000 in four years. What type of problem is this? A. present value of an annuity B. present value of an amount C. future value of an annuity D. future value of an amount The correct answer is B. 3. Someone will pay you $10,000 in four years. You want to know how much it is worth to you now, assuming a certain interest rate. What kind of problem is this? A. present value of an annuity B. present value of an amount C. future value of an annuity D. future value of an amount The correct answer is B. 4. What single amount do you have to deposit in the bank now in order to be able to withraw $200 a month for the next five years? What kind of a problem is this? A. present value of an annuity B. present value of an amount C. future value of an annuity D. future value of an amount The answer is A. Even though a single amount will be deposited, it is still an annuity problem. Hint: any time a problem involves equal periodic payments, use an annuity table. 5. When you were born your parents set up a trust fund designed to accumulate $88,000 by the time you are 50 years old. You are 34 years old today. If you negotiate getting the money today, what will you get? Assume an 8% interest rate and annual compounding. First realize you are looking for present value. Today and now are hints you want present value. Next realize you need to subtract your current age for 50 years to get the number of years, which would be 16 years in this problem. So PV = FV X PV table factor for 8% and 16 years 25,687 = 88,000 X .2919 6. You are very rich and will be retired soon. You want to take out $416,000 every six months for 6 years. You can get a 6% interest rate. How much do you need to deposit in the bank today to make this happen? You are looking for the Present Value of an annuity , since you want the amount to deposit TODAY, and you will be withdrawing equal periodic payments. So use the annuity table even though you are putting a lump sum in the bank. PV annuity = Deposit X PV annuity factor ( 3%, 12 semi-annual periods) = 416,000 X 9.9540 = 4,140,864, the amount you need to deposit today. 7. Trego County wants to raise $4,000,000 to finance the construction of a new high school. The school board wants to make semiannual payments to repay the loan over the next 15 years. What will be the amount of the payments assuming the interest rate of 10%?

Essay --

Aim: To measure the amount of oxygen takes in by the maggots and peas with the help of a respirometer in the experiment. Introduction: Respiration is the process by which organic molecules are broken down in a series of stages to synthesize ATP. Respiratory quotient is a measure of the ratio between oxygen an organism takes in and carbon dioxide the organism eliminates. The use of a device called a respirometer is used to measure an organism’s respiratory quotient by measuring the gases the organism takes in and exhales. Metabolism is all the chemical processes that take place in living organisms for example breathing, circulating blood and controlling body temperature. Since the peas and maggots used in this experiment are living things, they could affect the result since they both expire aerobically and take part in metabolism. With respiration of carbohydrates, the food is then converted to carbohydrates usually hexose sugar before being respired. There is an oxidation of glucose to carbon dioxide and water with the release of energy. Oxygen + glucose → Carbon dioxide + water + energy (in the form of ATP) When there is no use of oxygen it is anaerobic respiration and with usage of oxygen, this is aerobic respiration. In the presence of oxygen there are 4 stages namely glycolysis in the cytoplasm, link reaction and Krebs cycle in the matrix of the mitochondria and electron transport chain in the mitochondrial membranes. ATP is generated when H is lost and used to reduce coenzymes. The reduced Hydrogen carrier can be used to generate ATP by oxidative phosphorylation In the absence of oxygen the Krebs cycle and electron transport system cannot operate and only glycolysis takes place, which yields a two molecules for each g... ... in the sucrose solution contains carbohydrates. Food source would affect respiration, as each food source has a different energy values and respire in a different way. Appendices: This is calculated starting with obtaining the amount of carbon dioxide released by subtracting value b from value a. The respiratory quotient is then found by dividing the volume of carbon dioxide released over the volume of oxygen consumed Peas Maggots Mass (g) 5.60-3.93=1.67 5.06-4.00=1.06 Value (a) with KOH 3.50-2.00=1.50 4.25-2.50=1.75 Value (b) without KOH 3.75-3.75=0.00 3.50-3.00=0.50 Respiratory Quotient per unit 1.00 0.71 1) Volume of CO2 removed by peas is a-b (1.50-0)=1.50 RQ = (volume of carbon dioxide released)/(volume of oxygen consumed) RQ is 1.50/1.50=1 2) Volume of CO2 released by maggots is 1.75-0.50=1.25 With the RQ value is 1.25/1.75=0.71

Die Welle Essay

In the film â€Å"Die Welle†, directed by Dennis Gansel is about a teacher that is assigned to teach autocracy instead of anarchy. In the German setting, where the movie takes place, everybody knows that fascism and the Nazis sucked, they got that. Getting relegated to teaching autocracy was a real bummer since the students were filled with arrogance and laziness. Rainer Wegner constructs an unorthodox experiment, making an autocracy group of their own called â€Å"The Wave† or â€Å"Die Welle†. The real question is to what extent is an Autocratic government superior to all other governments or the counterpart the democratic government? For those who don’t know the difference between autocracy and democracy is that democracy is the form of government ruled by a group of leaders and a president elected by the people of the country. The leadership is chosen by the majority of the people. The epitome of a democratic government that is most known to us is the United States of America. On the other hand, an autocracy is basically a dictatorship is when one person rules the country without any say from the public. The people don’t have any saying at all in how the nation is run. An incredibly good example is Nazi Germany. Die Welle can be considered an allegory to modern day neo-nazism or old nazi Germany. The wave is just like hitler and the nazi group. It can make us reflect if a way of knowing, which is history, can be indeed true. How can we know something is right if we didn’t observe it first-handedly? We can think of it like this way, we can know that modern history is usually accurate since we were present at the times these events happened, and we concur that the events did indeed take place in that certain time frame. History is like police work, you piece together what one thinks happened based on the evidence available, like eye-witnesses or crime scene evidence. Historians can acknowledge these evidence and can say what happened during that time frame based on the evidence provided to us, like the police work. Nazis are basically the same thing since we study the evidence provided to us, like the video and artifacts of Nazism. In the movie, Die Welle, we can allegorize the events that occurred in the movie since after the autocracy nded, the students had many different perspectives about what happened. The events that occured in the movie can be seen in many different ways, it can be seen as very unorthodox since the experiment caused chaos and ultimately a student to get shot. Much like the Nazi-soldiers when their reign was over, many just panicked and killed themselves because they could not handle, the truth, that it was over. Much like when the wave ended and the kid took out his gun. George orwell said: â€Å"Who controls the past controls the future†. Does this relate to historical knowledge? To what extent can we trust historical â€Å"knowledge† since we didn’t experience it first-hand? This is a question we should all ask ourselves since this knowledge issue applies in a colossal way to the movie. We saw autocracy as a bad thing since it caused so much damage in the community, and even one youngster getting shot. Can we think of a way of governing a body of people as good or bad since it has been seen to be proven effective throughout history? As the movie quotes, â€Å"autocracy provides discipline†. It’s like an opiate for the masses since an ideology can rule them all. In conclusion, the movie can be seen as a knowledge issue in historical facts since we weren’t there to experience the allegory between Nazi Germany and the Wave autocratical group. It also relates to, is all knowledge historical knowledge? Since we have history, we should learn from our mistakes. A good quote that shows why the wave is so representative of national socialism is: â€Å"You’re pissed off just because The Wave does not follow your rule! †.
