...only in living tissues. A few years later, in 1800 Alessandro Volta discovered that electricity could be produced through inorganic means. In fact, by using small sheets of copper and zinc and cloth spacers soaked in an acid solution, he built a battery - the first apparatus capable of producing electricity. Naysayers were quick to predict that electricity would never serve a useful purpose. Obviously they were very wrong. Electricity has a central role in our lives and to this day Electrochemistry is a standard course of study. While listening to lessons on Electrochemistry, many students may wonder why it was ever invented, if it was really ever necessary to invent it and if the world would be better off without it. With the small experiments that follow, we hope to make peace between these students and the study of Electrochemistry. These fun and simple experiments can teach the fundamental concepts of Electrochemistry without asking much of the student. As you will see, many of these demonstrations are easily adapted to various configurations and each can be done independently or as part of the full curriculum. POROUS VASE - An actual porous vase made for the purpose may be difficult to acquire. It is used to prevent the quick mixing of various solutions, while permitting the exchange of ions. For our purposes you can adapt a terracotta pot of the type used in gardening simply by plugging the hole in the bottom with molten wax and allowing it to cool. Another even more economical...

...Compare and contrast Aristotle’s and Plato’s conception Compare and contrast Aristotle’s and Plato’s conception of the state and political freedom Politics and state have been following people’s society since it was established. Everybody understands that there is impossible to live in the world where there is no order. Every person still appreciates the necessity of state and government even if he or she does not as if the way of ruling is their own country. The problem of state was the topic of researches and thoughts for different famous people of ancient and modern time. Two of the greatest philosophers Aristotle and Plato devoted great part of their philosophic researches to the topic of conception of the state and political freedom. Let us compare and contrast their conceptions. A man named Aristotle who was a Greek Truth-seeker, a logician, and a scientist has a teacher named Plato. Aristotle is widely known as the most prominent olden philosopher in many areas of philosophy, together with political hypothesis. His life appears to have inclined his political notion in different conduct: his biological interest has mixed in his political life. Also, his political interest and his compassion for the democratic system like dominion perhaps have been optimistic by his experience of various political systems; he condemned severely, while borrowing widely, from his teacher’s (Plato) democracy, statesman, and laws; moreover, his own political affairs is proposed to help rulers...

...FINAL REPORT OF “SHOPPING PATTERNS OF THE PEOPLE INSIDE THE GIFTS SHOPS AND HOME DÉCOR SHOPS – A COMPARITIVE ANALYSIS (September 4, 2010) In partial fulfillment of the requirements of the course "Retail Marketing" of MBA (Full Time) CARD AND GIFT: For the past decade or so the gift and card industry has been growing at a rapid rate and gaining market share. At the whim of discretionary spending, gift shops and card stores rely on low-margin, high-volume sales and are finding it increasingly difficult to compete with supermarkets and online retailers. The key to survival is consolidation and vertical integration which is seeing the number of companies decline while store numbers edge up. The cards and gift shops fall into the impulse purchase category. The product mix includes: cards, collectible gifts, gift wrap, holiday and seasonal decoration, novelties, party supplies, souveniers, etc. Gift shops come as both standalone stores as well as part of supermarkets. In India these stores are franchisees, chain retailers, as well as independent retailers. The customer base is spread over a wide demography, but the main consumers are young. Some of the main players in this category are: Archies: [pic] Archies was founded in 1979 as a mail order poster shop, and introduced its first line of greeting cards in 1980. The company procured its first ever foreign license from Walt Disney, USA in 1984 and offered its customers some of the best loved Disney characters...

...Social psychology What is social psychology? It is the scientific study of how a person’s behavior, thoughts and feelings are influenced by the real, imagined or implied presence of others. Social influence: The process through which the real, imagined or implied presence of others can directly or indirectly influence the thoughts, feelings and behavior of others. Types of Social Influence: 1. Conformity: Conformity is seen wherein a person changes his/her behavior to more closely match the behavior/actions of other people. For example, Solomon Asch’s an experimenter had studied on conformity by experimenting some participants on their behavior pattern. The participants in his experiment were shown 3 comparison lines. They were later shown the standard line and were asked to determine which of the 3 lines matched the standard line. It was then found that the one participant followed what others said, despite of having his own answers to the question asked. 2. Group think: It is a kind of thinking that occurs when people place more importance on maintaining group cohesiveness than assessing the facts of the problem with which the group is concerned. For example, sinking of the Titanic in 1912, wherein the group responsible for designing and building the ship assumed that she was unsinkable and did not even bother to include enough lifeboats on board for all the passengers which caused the life of many people. Characteristics of Group think: a. Invulnerability:...

...frequently characterized by disintegration of the alabaster; the cohesion between the grains is completely lost. The reasons of the observed deformation dramatically for repeated heating may lead to permanent dilatations due to microfracturing. Variation in moisture contents may be responsible for the deformation. Water is one of the main factors of decay of alabaster stone which one of the porous stone at Karnak and Luxor temples, as it plays a crucial role in almost every decay process, water penetrate into the pores of the stone by many ways as capillary suction from the soil or by condensation from the atmosphere. Thus water carries into the stone soluble salts which can crystallize in correspondence of the evaporation surface owing to the solution supersaturation. This process is the main cause of the efflorescence and subefflorescence formation. Halite and gypsum are the common salts at the alabaster stone in Upper Egypt. Halite and Gypsum are hygroscopic salt...

...Countries – LDC’s) mothers in general were unable to feed their children with all the needed nutrients that a normal child must have, this is basically why the infant formula was created. The infant formula was created by companies in the pharmaceutical industry and Nestlé. Nestlé easily got a high market share in the industry. The general health problems in the aftermath cause a great impact on babies. The number of sick babies increased all the time after the Second World War, because there weren’t the needed minimum required measures of neatness for babies, like sterilized nipples, clean water, clean environments, etc. So breastfeeding wasn’t enough to keep a baby healthy over those years. The infant formula seemed to be a good solution providing the enough amounts of nutrients for a baby. The problems started after the meeting of infant-feeding practices in 1970 and 1972, Bogota and Paris, where a resolution was made: “The report concluded that breast milk was the best food for infants and, if in sufficient supply, would satisfy the need of a child up to 4-6 months. In cases where breastfeeding was insufficient or impossible, the use of nutritional substitutes was encouraged”. The debate created some years before these meetings and the years after seemed to be an ethical issue, of whether if babies must be fed with the infant formula or with the breast milk. The objective of infant formula was misunderstood as a way of replacing the breast milk, most companies including...

...Alternative Energy Sources Geology Many people believe that we must depend on fossil fuels for energy, where as the reality of it is the earth provides an abundance of renewable energy sources. These energy sources can produce enough energy that we would never have to use fossil fuels again. Alternative energy is the use of other energy sources instead of the use of fossil fuels or nuclear energy. Solar power can be used to operate cars and provide electricity to homes and businesses. Hydropower can be used to provide electric power to small towns and cities. Geothermal power can heat up buildings or water to power turbines to make energy. Wind power can be used to pump water and generate electricity. So let’s start with solar power since it is the most known of the group. Energy from the sun is one of the most abundant resources available today out of the alternative group. It is one of the most important of the non-conventional energy sources as well, because it does not pollute the earth. “One of the reasons for this is that the total energy we receive each year from the sun is around 35,000 times the total energy used by man”. (Alternative Energy Sources) One way to capture the sun’s energy is through the use of solar panels made out of Photovoltaic cells, which are commonly called (PV) cells. These panels can be used on homes, businesses, greenhouses, water heaters, traffic lights, or grouped together as a solar power plant. PV cells can transform the sun’s energy...

...| Introduction The term polygamy, meaning "the practice of multiple marriages", is used in related ways in social anthropology, sociobiology, and sociology. Polygamy can be defined as any form of marriage in which a person has more than one spouse. In social anthropology, polygamy is the practice of marriage to more than one spouse simultaneously. Historically, polygamy has been practiced as polygyny, meaning one man having more than one wife; or as polyandry, meaning one woman having more than one husband. In sociobiology, polygamy is used in a broad sense to mean any form of multiple mating. In a narrower sense, used by zoologists, polygamy includes a pair bond, perhaps temporary. Polygamy as stated earlier is the situation in which one man is either married to or involved in sexual relationships with a number of different women at one time (Magubane, 2003). This was the most common form of polygamy practiced by Mormons in the 19th century, and practiced today by self-identified fundamentalist offshoots (West and Jean, 2002). Polygamy existed all over Africa as an aspect of culture or religion. Plural marriages have been more common than not in the history of Africa. Many African societies saw children as a form of wealth thus the more children a family had the more powerful it was. Polygamy was and still is thought of as a part of empire building. It was only during the colonial era that plural marriage was perceived as taboo. Esther Stanford, an African...

...CHAPTER NINE Quantity, Logic, Time, Movement, and Velocity C H A P T E R 8 dealt with what might be called the first wave of Piaget's experimental assault on the development of intelligence in the postinfancy years. There was to be a second wave, of larger scale and longer duration. This second wave of research had a small beginning in the period 1935-1940 with a few scattered journal articles (e.g., Inhelder, 1936; Meyer, 1935; Szeminska, 1935; Piaget and Szeminska, 1939) and moved into high gear in 1941 with the publication of the first (Piaget, 1952b) of a long series of full-length books on various cognitive-developmental problems: number, quantity, logic, space, time, and so on. QUANTITY There are several studies which touch on one or another aspect of the child's grasp of quantity notions (Apostel, Morf, Mays, and Piaget, 1957; Fischer, 1955; Inhelder, 1936; Piaget, 1960a; Piaget and Szeminska, 1939; Szeminska, 1935). The earlier papers are primarily of historical interest, since their contents have for the most part been incorporated into the systematic book on the subject by Piaget and Inhelder, Le Developpement des quantites chez I'enfant (1941). This book is divided into four sections, each three chapters long. In addition, there is the customary chapter of summary and conclusions at the end of the book. The first section deals with what is probably the best-known segment of the quantity work: the so-called conservation of matter, weight, and volume of an object...

...Challenges and opportunities in recovering looted relics ----Starting from the auction in Paris of two Chinese bronze animal heads Introduction On February 25th, 2009, Christie’s, as the world’s largest auction house, proceeded the sale of two bronze animal heads, which were initially owned by China but lost in time of war, in Paris from the collection of the deceased fashion designer Yves St Laurent, fuelling great wrath of Chinese people. A NGO called APACE, together with a newly-established group of Chinese lawyers, applied to the “Tribunal de Grande Instance” (a court in Paris) for the “property preservation” of the two relics in order to sabotage the auction, yet the litigation was rejected since the judge held that the complainant doesn’t have the direct claim right. [1] Besides, Chinese government and individual collectors like Cai Mingchao also made their move against this auction, but China still scarcely makes any material progress in the restitution of the looted legacies throughout. [2] Such case reveals great challenges for countries like China to get back missing or stolen artefacts due to multi-faceted legal problems, and their harvests are often not in proportion with efforts paid. On the other hand, propelled by a huge profit, illegal antique trade has been showing a rampant trend in recent years. Its annual turnover is the second highest in all illegal dealings, merely lower than drug trade. [3] Given the lax law system on the protection of cultural relics...
