In What Ways did the Rights and Opportunities of Black Citizens in Different Parts of the USA Vary at the End of the Second World War Essay Example

In What Ways did the Rights and Opportunities of Black Citizens in Different Parts of the USA Vary at the End of the Second World War Essay After their independence from slavery in 1865 African Americans remained one of the most prominent ethnic minority groups in America. It was the end of the Civil War, however, and the Southern Confederate States had lost. This was the beginning of a growing resentment that caused the continent to be divided almost completely, due only to the colour of the peoples skin. It began after the Civil Rights Act of 1866, where it was declared that all persons born in the US were now citizens, regardless to race, colour or previous condition. Two more amendments were passed that gave equal protection to all persons under the law and also stated that a citizen could not be prevented from voting due to his colour or race. Yet despite these legal changes, not much was actually done to help black people and as they lacked money and resources, many blacks found themselves forced into contracts with their previous masters. This became known as sharecropping and by the 1930s, up to 75% of African-Am ericans were working on cotton plantations, for very little money, in the rural areas of the Southern states. But around this time, the Northern cities, such as Chicago, were expanding and industrialising so many blacks were moving northwards to take advantage of new employment opportunities. This was called the Great Migration, however, due to the Wall Street Crash of 1929 and the subsequent plunge into Depression, African-Americans found it difficult to begin a new life under the racial tensions and discrimination. It wasnt until the Second World War, which began in 1941, that black Americans finally had an opportunity to see a better way of life. And yet, in 1945 when the war was won, black rights were very different all over the country. While some had possibilities of education, employment and happiness others were striving purely to live above poverty and all this occurred with deep racial tensions running the breadth of the nation.A key element to the difference in opportunit ies and rights for black Americans came in the varying forms of segregation all over the country. (Although normally strictly imposed, during the Second World War, the Government found it necessary to desegregate many parts of the Armed service for more efficient combat, such as the Navy and in the front line. This gave a blacks a real taste of what freedom could be like for them.) Many states passed legislature that discriminated against black people, these were known as Jim Crow Laws and consisted of the separation of blacks from whites in many areas of society such as at the theatre and at schools. The south enforced these rules religiously and firmly punished any Negro who didnt know their place.And yet although segregation happened in the North, it was much more a mutual agreement and it was respected that blacks had their own communities which cropped up parallel to the whites. There was much more freedom for black people to own their own businesses and go to local pubs and cl ubs whereas the southern African-American population was far too poor to do much than work several hours a day, often being tricked by their bosses into losing money. Of course living in the North wasnt instantly an equal life for all. Many African-Americans were still victimized and stuggled to get by on poor wages. But the North still seemed a far better way of life for them and many continued to travel up in search of it.The segregation started after a white-skinned black American sat in a carriage reserved for white passengers only. His name was Plessy and he was arrested after refusing to move. He appealed his conviction to the Louisiana Supreme Court yet failed so attempted again at the Supreme Court of the US. In 1896 it was decided that separate but equal was not a breach of the 14th amendment and the Plessy Vs Ferguson case became the starting point of American segregation. Obviously the black facilities were not equal to those reserved for whites which included water fount ains, parks, sport facilities, prisons, transport and cemeteries. This racist separation continued right up until almost the end of the 20th century as hatred still brewed amongst white Americans about the rights of blacks. In 1945, however, segregation was still going strong in the South and opportunities for equality were still extremely frail as shown by the average total spent on each child in school, $179 for every white child and $43 for every black child.Black teachers were also paid half as much as white teachers. This led to enforced racism as black and white Americans were exposed to eachother in unequal statuses. It was also significant as it began a growing determination in African Americans to make their lives better which is why membership to the biggest pressure group for their advancement, grew from 50,000 to 450,000 in 1945. The National Association for the Advancement of Coloured People (NAACP) was set up in 1909 to improve the lives of black people in America. It funded court cases and set up demonstrations. Another reason for the steep increase in membership may have been because blacks became as determined to stamp out racism in America as much as they had stamped out fascism in Germany.Due to the differences in segregation laws, both the north and South provided opposing job opportunities for blacks which led to a migration northwards. After the war, sharecropping was still a major part of African-American lives in the rural areas of the South. The poor pay limited the conditions of the workers lives and many lived in small wooden shacks on the land they were expected to work on everyday. Often working from an extremely young age, children didnt tend to get an education which led to many illiterate adults in the years to come. These adults could then be easily tricked by their landowners into paying out more that they should as they couldnt understand the paperwork. Sharecropping was backbreaking work and even more so in the burning heat of the sun. However, in the north, there was an increasing amount of lawyers, teachers and politicians emerging from the African-American scene. Obviously still a tiny proportion of the black community yet enough to show that their was hope for the them yet.The reason that blacks in the north had better chances for success is not because the north wasnt racist, unfortunately blacks faced discrimination almost everywhere in America, but because there was a mutual tolerance that suggested as long as Negroes worked hard and behaved well, they could be left alone. Due to black pressure and general modernisation of the country, small employment improvements started to be made. Black people were employed in aircraft industries for the first time and the current President, Roosevelt, set up the Federal Agency to promote employment equality within the defence industries. To have the Government getting involved was a major achievement in the Civil Rights Movement.Employment was not the only thing beginning to flourish for black Americans, their culture and music was breaking barriers and raising morale for the common man. Jazz clubs in the north buzzed with loud music, dancing and happiness. Blacks celebrating their victory against Germany and the victory they knew they could achieve against racism, the double V. Black music was different to anything America had heard before as it had soul. You could hear the suffering that these people had endured in their voices alone as well as the optimism they had for the future. Using mostly saxophones, clarinets and trombones, African-Americans created an art form to be proud of.After the threat of war people had become more laid back, more ready to let their hair down or the music was used to commemorate those lost to war. Yet in the South, blacks found it difficult to get time for music in the same way. Instead they would sing their blues while they worked. Often an almost wailing quality to their voices, workers would sing fo r hours to pass the day away. They went to secret locations called Duke Joints where they would meet, as far away from white people as possible, sing, dance and drink homemade alcohol. But it was a much more underground affair. However, it was still a great morale boost for blacks even though their chances to sing varied throughout America.The most important variation in black rights after the end of the war, should come however, from the political and legal differences. In 1944 black political rights increased because of the case of Smith and Allright. The exclusion of blacks from primaries (election of candidates for governmental positions) was considered unconstitutional by the Supreme Court and black voters increased in the South from 3% to 12%. Some black people were even elected for state legislature though of course not in the south. Nevertheless as black rights increased, so did opposition. Many white politicians were strongly against black government officials and politics very rarely got involved with any cases of racism from the country. (As proven with the murder of Emmet Till almost 10 years later where the Government never intervened). This is confirmation that black rights were very different to the opportunities that existed in practise as black Americans were supposed to be protected by the Government under the 15th amendment yet not surprisingly, they werent. This happened with many supposed rights that blacks were given.To see the social, cultural and political diversity in the different parts of America is really to view the rights that blacks were theoretically given. According to passed laws and various evidence, it seems that living in the North was a far better way of life for black Americans and that it would welcome home black soldiers whereas the South was extremely racist and almost Neanderthal in their views. Yet in real life the differences were quite small between the two areas. Racism still brewed, race riots still took place if black people began to be treated fairly and the Ku Klux Klan still occasionally lynched no matter where you were. If an African-American made it to a high position, they would still face stiff opposition and would never receive the respect deserved. Although the standard of living for blacks may have been slightly higher in the north, none were yet receiving the rights or opportunities that every person warrants and it was years afterwards that they finally began making progress.

Jamestown vs Plymouth essays

Jamestown vs Plymouth essays Despite the fact that the original British settlements in Virginia at Jamestown (1607) and New England at Plymouth (1620) were founded in the same relative time period, the two colonies differed greatly economically, politically and socially. Economically, Jamestown was originally wholly dependant on money from the crown and later became dependant on a single cash crop, tobacco, while New England became self sufficient by farming all of their own food. Socially, New England colonists were a close-knit religious group of Puritans that came to escape religious persecution in England. The settlers of Jamestown were upper-class nobles who went to America in search of gold. Politically, Jamestown was set up with a more centralized government and had direct rule from the king. Plymouth had a very decentralized government made by its very own social contract and had no direct rule by the king. Although both settlements were initiated by the same joint-stock company, the London Company of Virginia, the two colonies were extremely different economically. With the help of local Indians, the pilgrims were able to become economically self-sufficient. Farmers were able to produce their own food, many of whom produced excess which they used as trading power to get furs and other goods from the natives. Jamestown, however, was almost completely dependent on money from the British crown for materials. Later, with the help from John Rolfe, Jamestown was able to produce something of value to support itself: tobacco. Tobacco was able to command high prices in Europe, and Jamestown became dependent on a single cash crop. The two settlements also differed socially. The pilgrims came from a society of Puritans who already knew each other. This allowed these settlers to more easily create a close-knit, strong community. Because of the religious persecution these people received in England, the Pilgrims mostly came to America for religio...

Housing for People with Special Needs Essay Example | Topics and Well Written Essays - 1000 words

Housing for People with Special Needs - Essay Example The essay "Housing for People with Special Needs" summarizes the different areas of affordable housings especially associated with the low-income households. The areas covered include special housing needs of elderly and disabled households, discriminatory behaviors and the fair housing programs, home ownership, and income integration. In the real estate and mortgage market of US, the discriminatory behavior has been convicted as illegal by the federal government at all levels. Certain legislations have been made in this regard which demonstrates the illegality of the discriminatory practices in the real estate and the mortgage market including Supreme Court decision of 1948, Fair Housing Act of 1964 and lastly, the Community Reinvestment Act of 1977. With the passage of time, most of the kinds of discriminatory patterns and behaviors in these markets are declared as illegal after enforcement of such legislation by the federal government. The enforcement of fair-housing legislation although has remained inconsistent such that discriminatory behaviors have not been total disappeared, yet there is evidence which shows a real progress in this regard. The evidence reveals that in the real estate housing market, there has been a significant reduction in the discriminatory behavior in relation to house purchasing and renting in the 1990s. Similar kinds of evidence are found in the mortgage market, where the Whites are left way behind than Blacks and Hispanics in relation to home-purchase.

Internetworking Essay Example | Topics and Well Written Essays - 1750 words

Internetworking - Essay Example It was introduced in one of the oldest wide area network - ARPANET. It is a widely used architecture because most of the computers and networks are configured to follow this suite and it is open to all. The TCP/IP reference model is a 4 layered model. The layers from top to bottom are Application Layer, Transport Layer, Internet Layer and Host-to-Network Layer. A data in a computer is going to the network from the Application Layer to the Host-to-Network Layer through the intermediate layers. Data from the network is getting to an application in the reverse order. Application Layer consists of certain higher level protocols like TELNET (for remote login/ to get a virtual remote terminal), FTP (File Transfer Protocol), SMTP (Simple Main Transfer Protocol), HTTP (Hyper Text Transfer Protocol), DNS (Domain Name System) protocols etc. The protocols in this layer will produce messages smaller in size to become compatible with the Transport Layer for an outward data flow and join the data messages to the original data for the application in case of inward message. Transport Layer consist the protocols like TCP (Transmission Control Protocol) and UDP (User Datagram Protocol). The reliability and the error checking of the data are managed here. This layer is responsible for the communication between two computers. ... The two versions of IP are IPv4 and IPv6.The lowest layer is the Host-to-Network Layer and this layer has the direct contact with the networking hardware. The data in this layer will be in the form of frames or byte series. Few protocols like PPP (Point to Point Protocol) are available in this layer. One of the most useful services of TCP/IP is the naming service it provides. Information sharing and exchange on an Internet work become easy and comfortable through this. The most widely used naming services are NIS (Network Information Service) and DNS (Domain Name System). NIS is used to provide information that has to be known throughout the network, to all machines on the network. There will be NIS server to keep all the information for the NIS. In case of a UNIX system, the configuration files handled by NIS are /etc/group, /etc/hosts, /etc/netmasks, /etc/passwd, /etc/protocols, /etc/rpc, and /etc/services. For setting up NIS, we have to set up both the NIS Server and NIS Clients. DNS is used for naming a host uniquely on a network, especially on the Internet. In this IP addresses of the computers or other interfaces are mapped to certain names with a typical naming strategy. Each group of similar computers is included in same domain and the domains are created in a hierarchical manner e.g. for the top level domains are .com, .net, .org etc. The details of the naming are stored in the DNS Server as resource records. There are two types of mapping files. The forward mapping file is used to convert names to its IP addresses and reverse mapping record is used to convert IP addresses to its symbolic names. Format of a resource record entry is as follows. Name (variable length) type(16bits) class(16bits) ttl(32bits) data For DNS configuration in a UNIX system, we

MARKETING DEBATEIs Service Marketing Different From Product Marketing Essay

MARKETING DEBATEIs Service Marketing Different From Product Marketing - Essay Example factor has been at the core essence of any organization mainly due to the fact that it is the ultimate resource which brings about completion of work and duties. People factor in the service encounter gains an even more significant position. Thus a company can move from a position of stability to one of a complete unstable stance as it acquires different means of gathering the market and its driving factors that come along with it. (Lazer, 1971) Thus the differences between the present day service marketing and the traditional product marketing in the ranks of the small and the large businesses asks of the marketers to learn the same so that they could understand for their own betterment what the present day marketing regimes could bring about and thus benefit all and sundry. The intention behind marketing is to make people aware of this form of business which is all about the propagation of knowledge and information related with the product/service in mind and the company which is making it available for one and all. (Bailey, 2000) With that, one understands that the foundation of marketers will be strong so that they could step right into the practical world and do not feel at sea when the business plans and the marketing strategies are discussed with regards to different products and brands. Thus marketing is taught in colleges for imparting the much valuable information and the precise details of the insight that would enable one and all towards the issues which a person could encounter in his practical life. (Aguirre, 2001) From a standpoint of small and large businesses, product and service marketing is in fact a battle ground for learning a lot of things which are related with the psychological basis since understanding the psyche of the consumers beforehand can be the starting point for comprehending as to what they actually want and what they should be offered in terms of the product offerings and services mix. Coming from the quarters of the present day

Induced Electromotive Force in Potatoes | Experiment

Induced Electromotive Force in Potatoes | Experiment I was first introduced to vegetative electric energy during my freshman year in high school, when our chemistry teacher showed a lemon battery at work as we were studying Electrochemistry. I got very intrigued with the idea of generating electricity with lemons, and I later learnt that many organic substances exist which can also produce electricity. The next year of my high school, I heard about the global consumption of power, and how the earths natural resources were getting depleted, and got an idea that if natural organic batteries were developed, the resources of the earth would remain stable. Thus I took up this study to help me explore the possibility of organic fuel cells and its capability of generating electromotive force. For this study I will take potatoes into consideration because of their high acid content and the relative accessibility of it. The acid responsible for the generation of EMF within the potato is Phosphoric acid, but my experiment will deal with what causes the change in the EMF when the potatoes are boiled. Initially I thought the cause lied in the varying concentration of the electrolyte, but upon further study and research found the reason to lie within the cell membranes of the potatoes that get ruptured during the boiling process of the potatoes, thereby varying the EMF generated. After maize, wheat, and rice, potato is the worlds fourth most important food crop with an annual production of more than 323 x 106 tons with more than one-third coming from developing countries. Thus if potatoes do prove to be beneficial asset, it can able easily adopted by those who are lacking electrical infrastructure as part of the daily routine since it is cheap and requires no special skills for assembly. RESEARCH QUESTION: How does the induced electromotive force generated from the potatoes depend on the state of the potato (i.e. Fresh potato vs. Boiled Potato)? INTRODUCTION: The first batteries were researched and invented by Volta when he made a device capable of producing electricity by the mere contact of conducting substances of different species. The invention of Voltaic battery had marked the birth of a new era in the development of modern physics and made a significant change in our lifestyle. Battery technology has without a doubt seen progress, starting from it being dependent on organic/biological matters to it becoming more efficient using inorganic-reaction-based technology. However from the end of the 20th century, biological batteries were just a mere science experiment performed in highs school, however with the growing concern of depleting the earths resources, there has been a new found interest in the development of organic fuel cells. In order to highlight this growing interest, I have performed a study regarding the basic school experiment of a potato battery. For the first part of my study, I will perform the normal experiment by making a potato cell, using Zinc and Copper electrodes and recording the electromotive force (EMF) generated. Now, for the second part, I will boil the potatoes and record the readings of the EMF generated. I will compare the two results, and comment about my observations, and make possible conclusions about why there is a change in EMF generated or why there is no change in EMF generated. BACKGROUND INFORMATION ELECTROCHEMISTRY Electrochemistry deals with the inter-conversion of electrical energy and chemical energy. This study will deal with the conversion of chemical energy into electrical energy (Electrochemical Cells). An electrochemical cell mainly consists of two major components: left hand electrode (LHE) and the right hand electrode (RHE). In LHE, oxidation (loss of electron) takes place and is called the anode. In RHE, reduction (gain of electron) takes place and is called cathode. Anode is generally of that metal (or substance) which readily loses electrons (i.e. Oxidized easily). Cathode is a metal which readily accepts electrons (i.e. Reduced easily). There are two specific ways in order to create an electrochemical, voltaic or galvanic cell. Method 1: Put the LHE (anode) into the solution of the electrolyte of the Cathode (containing the ions of the cathode). This allows the anode to loose electrons per atom and the ions present in the electrolyte accept the electrons. Thus, the cathode ions from the solution in this manner get deposited in order to form the metals of the respective cathode and the metal anode goes into the solution as ions. The reaction can be understood with two half-cell reactions: Oxidation M Anode (S) Mn+(aq) Anode+ ne- Reduction: Mn+(aq) Cathode + ne- M Cathode(S) _ ___________________________________________________ Overall Reaction: M Anode(S) + Mn+(aq) Cathode M Cathode (S) + Mn+(aq)Anode Where, M Anode(S) is the element that gets oxidized at the anode, M Cathode(S) is the element that gets reduced at the cathode, ne- is the number of electrons lost/gained during the reaction A rod of that metal is prepared and placed into one of its own solution in LHE to get anode. In RHE, a rod of metal that loses electrons less easily as compared to the metal of LHE is prepared and put into one of the solution to get the cathode. LHE and RHE are also known as two-half cells. Now the electrons move from anode (LHE) to cathode (RHE) and hence a current flow is maintained in the external circuit. This current flow is due to the fact that a potential difference is created this and this is called the E.M.F, electromotive force of a cell. The two separate containers are connected by a inverted tube U shaped tube called as salt bridge. The salt bridge contains solution of strong ionic salts like NaCl, NaNO3 and KCl etc. (salts of most reactive alkali metals) soaked in colloidal solution of agar-gel which only allows movements of ions, not water. The role of the slat bridge is very important as it allows the continuous discharge of the cell. The salt bridge keeps the two solutions electrically neutral to one another. In the Fe-CuSO4 cell, in the left cell as Fe loses electrons, excess of positive charge in the form of Fe2+ is collected near the LHE and as Cu2+ ions gets discharged accepting electrons form Fe in the right hand cell, excess of negative charge in the form of SO42- is accumulated near the RHE. Now the salt bridge provides positive charge to RHE (in form of K+ ions) and negative charge to the LHE (in the form Cl-) and thus bringing about the neutrality of two solutions. If this does not take place, a reverse potential difference is created in the two compartments and thus breaking the continuous supple of voltage (current), which is the purpose of the cell. The efficiency of a cell is determined by the tendency of LHE to loose electrons and the tendency of RHE to accept electrons. A measure of cell efficiency is called as electromotive force (EMF) or the voltage or the difference in potentials of two electrodes. EMF is defined as the difference in the potential across LHE and RHE to which electrons from anode travel to cathode. My experiment consists of the above explanation with regard to a Secondary Battery or also called Galvanic Cell, which uses the main principles of the method mentioned above, but lacks a salt bridge but the cell membranes within the potato act as a salt bridge. The electrolyte in the potatoes is the phosphoric acid which does not actively participate in the reaction, since its main purpose is to make Zn loose electrons by oxidizing it, the potato provides the protons and the Cu plate remains unaffected by the acid bath. My storage battery is the potato, with the anode plate is made up of Zinc (Zn), while the cathode plate is Copper (Cu). The electrolyte which initiates the reaction or makes the reaction possible in potatoes is phosphoric acid (H3PO4). My experiment will involve the use of iron nails (Zn+2/Zn) acting as anode, and copper plates (Cu+2/Cu) as cathode. These are placed in an electrically conductive solution that allows  ions  to travel freely between the two metals in this case potato. The acid steadily eats away at the Zinc, a chemical reaction that releases spare zinc  electrons. These electrons then join with spare  hydrogen ions  in the acid to create hydrogen gas. Meanwhile, the copper remains unaffected even when submerged in acid but as soon as a conducting wire is connected between it and iron electrons flow from copper to Iron. The spare iron electrons are still intent on forming hydrogen gas, but they have an easier time doing it with the hydrogen surrounding the iron anode. So the electrons from the copper cathode travel through the wire to get to the iron. Batteries exploit this flow of electrons, therefore producing induced EMF. In most of the batteries, there is internal resistance which makes it impossible for the battery to produce 100% of its maximum potential difference. The same is applicable for the potato battery in the form of GAII (Galvanic apparent internal impedance, a trait related to both the salt bridge function of a given tissue delineated between electrodes and to the battery internal resistance properties). This electrical impedance can be a classified into further categories which is out of scope of this study. But the concept of GAII is useful as it can explain the relation between the EMF generated from a boiled potato as compared to a fresh potato. Thus the EMF generated from one potato is because of the potential difference created by the electrodes as in the above mentioned cases. But since the number of potatoes remains constant, the reacting species also is constant, i.e. when two potatoes are used, each potato will have an zinc and copper plate, and thus when the zinc gets oxidized by the potatoes, same electrons will enter the iron electrode from the copper, thus EMF generated should be same. But this is where my experiment differs. MY ORIGINALITY: Experiments have already been conducted on fresh potatoes and the induced EMF but, I planned to boil my potatoes and observe the readings of the EMF generated and compare the results obtained from performing the experiment with raw potatoes. The potatoes by default will be similar and will be microwaved in KCl solution for scientific vigor, and then after certain attainment of room temperature, the EMF generated will be recorded. The readings and the graph will make clear weather the boiling of potatoes changes the EMF and what makes the EMF generated to change. MY HYPOTHESIS The induced EMF generated from the experiment being performed with boiled potatoes compared to raw potatoes will decrease since the concentration of phosphoric acid will decrease, since the potatoes are boiled in aqueous solution, thus diluting the already present phosphoric acid, and thus since the concentration of the electrolyte decreases so will the rate of oxidization and reduction, eventually leading to the decrease in the EMF generated. The GAII may also play a part since when the potatoes are boiled the inner temperature of the potato increases causing denaturation and this might affect the flow of electrons thereby affecting the EMF generated. METHOD Battery Design Commercially available potatoes were used throughout, due to ease of accessibility and for economic factors. The mineral composition of the potatoes has been given in Table 1 of the appendix. I compared the EMF generated from cells made of potatoes treats as follows Raw/Fresh/untreated Boiled/treated For the preparation of the Galvanic cell, the potatoes in both cases were cut into 5x2x2cm and were sandwiched between the Iron and Copper plates. Potato Denaturation by Boiling I compared the electrical energy generated from untreated potatoes compared to that of treated potatoes. For scientific vigour, I immersed the sliced potatoes in 1 mol dm-3 KCl solution and microwaved at 800W for 5 minutes. Measurement of EMF The amount of EMF (V) generated was evaluated using a Vernier Lab Quest connected to the cell. The measurement was also taken for Current (I) and Power (P). These measurements were taken over a period of 2 hours over a constant load of equal resistance. In order to prevent the potato coming in contact with air it was covered with Parafilm in order to reduce drying and oxidation. VARIABLES INDEPENDANT VARIABLES: The independent variable in this experiment is the potatoes, or the state of the potatoes i.e. boiled or fresh. Thus the experiment will be carried out with fresh potatoes, and then further into boiled potatoes., For similar concentration, and volume of acid in potatoes, similar sized potatoes were taken so that the result will not deviate. The potatoes act as independent batteries, providing induced EMF as they are connected in series. The reason they act as a battery is because the copper and zinc electrode undergo redox reactions in the presence of the acid which acts as an electrolyte, which creates a potential difference and this is calculated to be EMF DEPENDANT VARIABLES: The dependant variable is the EMF generated by the potatoes when arranged in series. It will be measured with a Vernier Lab Quest which is connected to the computer The potential difference will be calculated, between the two extremes of the electrodes (anode and cathode => Zinc and copper plate). This given criteria is same for both the set up. The unit of measure is the Volt. The readings will be taken for two hours for each. CONTROLLED VARIABLES: The apparatus used was same throughout the experiment, since this will reduce mean deviation and the calculations will be done with respect to the other readings therefore, error is less The temperature in the room was controlled and was kept at 300K and this is with respect to the room temperature and not the temperature of the potato. The arrangement of the potatoes and the beakers was done in series since that would accurately judge between the EMF discrepancies between boiled and unoiled potatoes. Similar sized potatoes were taken in the hopes that the concentration of phosphoric acid would be similar; therefore the readings will not have much discrepancy relative to each other. When the potatoes were boiled, all were boiled to the same temperature, for the same amount of time, and were removed from the water bath at approximately the same time The apparatus was cleaned thoroughly before performing each experiment so as to reduce discrepancies in the readings, with respect to other readings. The amount of insertion of the Iron and copper into the potato was same throughout all the experiments at 3 ±0.1cm. The potatoes were all sliced up into the following dimension 5 x 2 x 2 cm and were sandwiched between the electrodes. The part of the potato exposed to the air was covered with Parafilm in order to prevent the potato from drying and reduction. CONSTANT VARIABLE: The copper plate and the iron nails used were the same throughout the experiment, so was the location where the experiment took place so as to keep all errors due to pressure and temperature constant. The same water bath was used to boil the potatoes, in order to keep the potatoes at constant temperature with regard to each other. The time taken for recording the EMF generated from the potatoes in both cases was taken as 2 hours. DATA AND GRAPHS ACTUAL REACTIONS TAKING PLACE Oxidation: Zn: Zn Zn++ + 2e- , E0 = 0.76V, Reduction: Cu: 2H+ + 2e- H2 , E0 = 0.00V Overall: Zn + 2H+ Zn++ + H2, à ¢Ã‹â€ Ã¢â‚¬   E0 = 0.76V REASON FOR THE REACTIONS AND ANALYSIS OF DATA My results conclude that Zn electrode and the reduction of hydrogen at the Cu electrode are the dominating reactions which give rise to EMF, Current Density and the potential difference. Maximum power delivered by boiled potato cells with ruptured membranes may reach values an order of magnitude higher than that generated by untreated potato. When the data was compared, a direct relationship between the ability of the potato battery to deliver power and GAII (Galvanic apparent internal impedance, a trait related to both the salt bridge function of a given tissue delineated between electrodes and to the battery internal resistance properties) becomes evident. The significant increase in electric energy generation with membrane destruction shows that the ionic diffusivity through the tissue bridge between electrodes is the reason behind this phenomenon, as effective diffusivity of protons increases with membrane rupture. In contrast, the rate of proton flux is reduced when cell membranes are intact probably due to the tortuosity of the extracellular space as well as the equivalent reduction in the concentration of the electrolytes per unit volume when the intracellular fluids do not actively participate in the ionic transport. CONCLUSION: From the data and the graphs it is clearly visible that my hypothesis was inaccurate, since the EMF generated did not decrease with the boiling of potatoes, but increased and also lasted longer under the same external load compared to the fresh potato. The potato serves only as a medium for the movements of electrons from the zinc electrode. The potato supplies the protons thus generating electricity. Fresh potatoes do it, but the strong internal resistance makes it very inefficient. Boiling the potato destroys membranes and possibly some part of the cell walls, thus reducing significantly the internal resistance and increase 10 folds the generation of power. The bio electrolytic low power electrical energy source introduced in this study brings an dimension to the utilization of the globally fourth most abundant crop accessible essentially all over the world, made of solid components and requires low financial investment compared with solar or conventional batteries. EVALUATION: The experiment was conducted in a non-ideal conditions which could lead to errors:~ Systematic Error: The Parafilm had foreign bodies or had an unwanted flaw which could have not given me an accurate reading The reading of the electronic balance may also have a manufacturing defect, thereby leading to a difference in the times taken. The lab quest may be defective or may have been inaccurate which may have given inaccurate results. The microwave may not have operated throughout the five minutes at 800W, thus leading to a variation in the temperature achieved by the potato in order to break the cell membrane. Random Errors: There might have been a gap or hole in the Parafilm leading to increased drying of the potato thereby affecting the EMF generated. Human parallax error when adjusting the volume of the solutions by taking only the lower meniscus. The apparatus used may contain remnants of other chemicals leading to an impure solution. The temperature of the room was taken to be constant, but there might have been fluctuation in the actual temperature thus leading to heat loss, and null results. The electronic balance might not have been zeroed out to take the new reading or might have had impurities which could have given inaccurate readings The microwave may not have run for exactly 5 minutes, thus leading to different boiling degrees EMF of the potato was taken every 3 seconds from the start of the reaction and thus the increase/decrease would not be exactly accurate, leading to a discrepancy in data.

What the Genome Revolution Could Mean for Me and the Rio Grande Valley :: Argumentative Persuasive Biology Essays

What the Genome Revolution Could Mean for Me and the Rio Grande Valley With technology advancing more quickly than even our own minds can comprehend, the effects of these advancements cannot be measured in our time, as they are just beginning to reveal themselves. Nowhere is this more evident than in the world of biotechnology, where researchers are changing the way people look at themselves as individuals with imperfections. The newly mapped human gene sequence provides scientists with the tools needed to manipulate, 'fix', or alter the human genetic code to create a person with any specifications desired in a human. Just the idea of a person engineered to specific criteria boggles the mind with questions about the implications on society, not to mention the unforeseen consequences that could lurk in the nearby future. In a world as populous as today's, the sense of self, rooted within each person, becomes more important than ever. As time passes with more hi-tech advancements, people will have to deal with the outcomes of the human genome project, some of which can be investigated before work begins on implementing research into everyday healthcare and others that still wait to be stumbled upon. The first problem includes the laws of all types, including those that have yet to be passed concerning the use of DNA in altering negative characteristics and adding favorable ones. First, developers must explore the ethical law that asks whether it is morally correct to change what it is that makes us people: the fact that we are all different and have flaws, and maybe these should be cherished rather than changed. If everyone was the same, we would become like ants, just one of a million, and lose the meaning of us being here: sharing different ideas and personas that enrich our lives and give us fulfilling relationships. Does making similar people interfere with the law of nature, which before now was the only factor in determining who we are? Then comes the legal matters that appear with the application of this knowledge. When people alter the natural cycle of life that has been in place for millions of years, there are going to have to be rules in place so that this sensitive data does not fall into the wrong hands, become misused, or have the huge negative impact on society that it has the possibility of having.

Alcohol Drinking in Germany

Alcohol has the tendency to be a cause of death for a vast number of people. The consumption of alcohol can also have a consequence on your brain which in turn makes you tremble at the same time as loosing control over all of your senses, and it can also kill parts of your brain cells. What is more is that alcohol consumption can cause your liver to depreciate and not function appropriately.Liver transplants are not easy to take place and they rarely take place. Even if it does take place it is hard for a person with liver transplant to survive for too long. Even though it is general knowledge that alcohol consumption has the tendency to kill people, still there are millions of people who consume great amounts of alcohol on daily basis (Martina, Gert, Eckardt and Klaus, 2003).As known to all, Germany is perhaps one of the most alcohol-drinking nations from all over Europe, ranking fifth right after Luxembourg, Hungary, Czech Republic and Ireland. Only a small percent of about five pe rcent of the people of Germany seem to call themselves as teetotalers, which are people who   completely abstain themselves from the use of alcoholic beverages, ranking it, after Luxembourg as the European nation that has the lowest percentage of people who do not drink at all.With reference According to the World Health Organization, and as has been proved by a vast number of studies, the whole of Europe is said to have the highest amount of alcohol consumption with comparison to all of the other parts of the world rating it per capita consumption as twice as high as compared with the average of the entire world.AnalysisAs has been mentioned before, the most prevalent problem in the whole of Germany is said to be of alcohol consumption abd dependance on it as well. This is a statement that has been verified by Peter Lang, who is basically the head of drug prevention and abuse at the German Center for Health Education (Ryan, 2006).Basically alcohol abuse is said to be the most com mon as well as the largest of all social problems within Germany. As is known to all, Bildunterschrift:   Ã‚  Ã‚  Ã‚  dangerous and detrimental using up is without a doubt connected with a number of psychosomatic, communal and physical condition problems, and in addition has a considerable economic bang on the social order as a whole.In the words of Peter Lang, â€Å"It's difficult to say what is causing this, because alcohol is more or less an accepted drug in a lot of circumstances, like for parties or other social occasions. If you compare Germany to countries like the US, there is drinking in public that is different and more accepted. Consuming alcohol during the day is really more accepted here in Germany,† (Ryan, 2006).

Free Essays on Charles Murray

Charles Murray’s essay â€Å"Choosing a Future† depicts what the future would be like if all federal transfer payments to the poor were abolished. Murray is convinced if our country did away with all federal transfer payments such as AFDC, Medicaid, Food Stamps, Unemployment Insurance, ect†¦ that our country would be better off. Murray seems to be overly optimistic about our future without welfare. Murray seems to think that every one who is on welfare and any other federal benefits would be forced to find a job. If they cannot find a job then they would have to rely on their families or private charities for support. Anyone who cannot achieve this would be considered to have â€Å"fallen between the cracks.† Murray states that this would be a very small percentage of the population and that we have no obligation to help them because they only have their selves to blame. I believe Murray’s speculation has noble intentions, but I think there is a point where he crosses the line. I agree with him that it is not fair for low class people who have a hard working job to earn basically the same amount as people who are just on benefits from the government. However, I don’t agree that all federal benefits should be cut. People who have a disability do not have the same opportunities as everyone else and there for I believe that they should receive some sort of benefit. If we resorted to this living style then I believe that humans would be no different then primitive animals. In the 19-century a famous British scientist Charles Darwin, known for his theories on evolutions coined the term Darwinism. Darwinism means only the strongest survive. This is what animals have to revert to. If your country eliminated all benefits then it would not be ludicrous to say that only the strongest will survive. I refused to believe that our civilization has not evolved more then animals....

Skokie essays

Skokie essays In the case of Village of Skokie vs. The ACLU(American Civil Liberties Union) I would definitely stand with the ACLU. The ACLU was defending the First Amendment Right. They were not defending the Nazis. We might not agree with what the Nazis are saying but, they still have a right to say it. Herb Lewison of the ACLU and the attorney for Collin stated to the judge Your Honor, this is a simple First Amendment case. The Village of Skokie seeks and order, preventing the exercise of free speech before the speech has even occurred, in spite of the fact that it has been proposed as an orderly exercise, taking place for only 20 minutes on public property in front of the Skokie Municipal Building. This section of the quote from Herb Lewison is simply saying that Skokie is just trying take away the first amendment right of the Nazis. Everything that they are asking for falls within their first amendment right. All they are just proposing is an orderly march. An orderly march for 20 minutes on public property. This is okay in my opinion because everything is offensive to someone. But you still have the right to voice your opinion. The second quote Lewison states is, This is a classic case in which government officials are asking a court of equity to impose a prior restraint on the speech of persons advocating unpopular ideas. Lewison is saying in this part of his summary argument that the government is asking the court to issue a prior restraint on the speech because they dont agree with their ideas. Another part of his quote states The Village of Skokie has shown only that the political views of Collin an ...

Learning and Decision Making Learning can be explained as a change that results from experience in the knowledge or skill that an employee poses, learning can be through reinforcement that is the use of rewards and punishment, observation and experience. In learning, classical conditioning implies that an employee’s response to a stimulus is not what would have been expected. Through operant conditioning, an employee learns by observing the how voluntary behavior produces certain consequences. To increase the desired behavior of an employee one can either employ the use of positive reinforcement whereby an employee’s desired behavior is followed by a positive outcome, or negative reinforcement whereby negative outcome is r idden off through a desired behavior.

The Role Of Stakeholders In Passing The Proposed Amendment 1 Assignment

The Role Of Stakeholders In Passing The Proposed Amendment 1 - Assignment Example Due to the dynamic nature of the world politics, the intended role of politicians voted by voters as slowly narrowed to self-centered interests. It is evident that majority of the politicians across the world, become active when discussing issues affecting their welfare, for instance, an increment of allowances (Gowing, & Arnold, 1974). On the other hand, they remain reluctant in passing proposed amendments in other sectors such as nursing. This is in contradiction with the noble calling to serve the subjects. This calls for stakeholders from all fronts including the nurses to participate actively or passively in the splendid role of spearheading passing of proposed amendment. It is notable that the stakeholders can participate in policy change through lobbyist’s influence (Bristol, 2004). The activists have the capacity to sway the subjects to vote for or against a policy; however, this depends on the past record in telling the truth in their bid to make their opinion superio r.In conclusion, it is a fundamental role for relevant stakeholders to participate in passing the proposed amendment because; the political class may ignore an important policy because of self-interest. It is notable that, the participation of the stakeholders creates a platform, which is irresistible in addressing key issues. This platform saves time in passing proposed amendment of critical importance to the large society, which involves subjects from all professional and unprofessional fronts.
