Trust, Deceit, & Immorality in And Then There Were None, a mystery novel by Agatha Christie, discusses matters of trust, deceit, and immorality. These two words are present within each chapter, and they come to us in ways that do not meet the eye right away. They require a certain level of thought in order to be understood clearly. In which Agatha Christie hopes to bring out. Trust is a key element of life. We need to choose who we can confide and believe in. If the ten people on the island want to stay alive, they need to be aware of those who are truly loyal, but they need to choose wisely, for one out of the ten is a murderer. Everyone in the house has there suspicions. No matter what the circumstances are, they remain immutable about not trusting each other. Having no trust makes all of them a nervous wreck, making each of them more susceptible of being the next victim of murder. Having no trust only digs us a deeper hole to the inevitable, and when we trust the wrong person, the inevitable happens sooner than expected. Deceit, unfortunately, is also a part of life. Deceit inside And Then There Were None, however, is a part of death. Lombard and Vera face the facts when they appear to be the last ones alive on the island. Instead of being the nice man he seemed to be, he turned out to be a miscreant. Lombard fools a lot of people with his act of being paranoid of having the killer looking over his shoulder. It is his self that he needs to guard, and he is not doing a good job of that, because Vera kills him instead. Death comes about in many ways. Murder is one of them. This immorality is the basis of the whole entire book. One by one, each one of the ten people die by someone else’s immoral actions. Even at the end of the book when Vera shoots Lombard, she had committed a brutal crime. Yes, she was defending herself, but she still chooses to use her hands to take someone else’s life. Immorality plagues society today deeply. We have twisted morals so much that the may think the most wr ong action is OK. And Then There Were None is a book that applies lives ways in forms that come to us unconsciously.

History of Volleyball

The History of Volleyball According to (Stengenth and Power of Volleyball), for the first time in the history of volleyball, volleyball was played in the Pan American Games in 1955. In 1957, volleyball was designated as an Olympic team sport by the International Olympic Committee (IOC). In 1959, the International University Sports Federation (FISU) had volleyball be one of the eight competitions held in first University Games in Turin, Italy. In 1960, seven Midwestern institutions formed the Midwest Intercollegiate Volleyball Association (MIVA). In the 1960's, new volleyball techniques were developed. Off-speed hits, open hand tips, forearm passing, blocking at the net, and defensive plays such as diving and sprawling become a big part of the game. With the FIVB already having its own world championships, the FIVB directed its attention to the Olympic Games. Thanks to the Bulgarian Volleyball Federation, a tournament took place in Sofia in 1957 during the International Olympic Committee meetings. As a result of this event, volleyball became an Olympic Sport. In 1964, volleyball was first played in the Olympics in Tokyo. Volleyball became a part of the Olympic Games, which allowed it to grow even more. Also, in the 1964 Olympics, the Japanese used a volleyball that consisted of a rubber casing with leather panels. A similar ball is used in modern volleyball competitions. In 1969, a new international event, the World Cup was introduced. The World Cup would be turned into a qualifying event for the 1991 Olympic Games. In 1974, Japan telecasted a major volleyball event in Mexico, the World Championships. In 1983, the Association of Volleyball Professionals (AVP) was founded by Leonard Armato. The organization started its own beach volleyball tour in the United States in 1984. By the late 1980's, the AVP tour was growing fast due to the promotion of the sport by the professional beach players Tim Hovland, Sinjin Smith, Randy Stoklos, and Mike Dodd. In 1986, the Women's Professional Volleyball Association (WPVA) was formed to administer, govern, and protect the integrity of Women's Professional Beach Volleyball. In 1987, the FIVB added a Beach Volleyball World Championship Series 1989 – The FIVB Sports Aid Program was created in 1990, a men’s volleyball competition called the World League was created. The World League is the longest and most flourishing of all the international events organized by the FIVB. The tournament is an annual event. In 2006, prize money became a major deal with $20 million dollars being distributed amongst 16 participating teams from 5 continents. The World League is sometimes confused with the other international volleyball competitions – Volleyball World Cup and Volleyball World Championships. In 1995, the sport of Volleyball turned 100 years old. In 1996, for the first time in the history of volleyball, beach doubles volleyball is included in the Olympic Games. Major events in the 90’s took place including the establishment of annual competitions for men's and women's volleyball (the World League, in 1990, and the Grand Prix, in 1993), the indication of Beach volleyball as an Olympic event (1996). These events and many rule changes in the game were made the purpose of enhancing the popularity and public visibility of the sport. William G. Morgan (1870-1942), invented volleyball in 1895 in Holyoke, Massachusetts. Morgan, who was born in New York, is known as the inventor of volleyball which he originally named Mintonette. Later, Alfred Halstead re-named Mintonette volleyball because the object of the game was to volley a ball back and forth over a net. Morgan studied at the Springfield College of the YMCA (Young Men's Christian Association) where he met James Naismith. Naismith, in 1891, had recently invented the game of basketball. During the summer of 1895, Morgan moved to the YMCA at Holyoke where he became Director of Physical Education. In this role, Morgan had the opportunity to direct a vast program of exercises and sport classes for male adults. His leadership was eagerly accepted, and his classes grew in large numbers. He came to realize he needed a different type of competitive recreational game in order to vary his physical fitness program. Basketball, which sport was beginning to develop, seemed to suit young people, but it was necessary to find a less violent and less intense alternative for the older members. Morgan took some of the characteristics from tennis and handball along with basketball. Morgan liked the game of tennis, but tennis required rackets, balls, and a net. He didn’t like all the equipment, but he did like the idea of a net. Morgan invented volleyball, which was originally called Mintonette. Mintonette was designed to be an indoor sport. Mintonette was less rough than basketball for older members of the YMCA, while still requiring some athletic ability. The first rules required for a net to be 6 feet 6 inches (1. 98 meters) high, a 25 ? 50 foot (7. ? 15. 2 meter) court. Each team could have as many players as a team wanted. A match was nine innings with three serves for each team in each inning. There was no limit to the number of ball contacts for each team before sending the ball to the other side of the court. (Stengenth and Power of Volleyball)In case of a miss serve, a second try was allowed. Hitting the ball into the net was a fault, with loss of the point or a side-out, except in the case of a first serve attempt. References (n. d. ). Retrieved from Stengenth and Power of Volleyball.

Lab Report Digestion Essay Example

Lab Report Digestion Essay Example Lab Report Digestion Paper Lab Report Digestion Paper These large molecules cannot cross last membranes intact to be absorbed from the lumen of the digestive tract into the blood or lymph; hence, it must undergo degradation in size (Sherwood, 2013). This degradation process is catcalled by hydrolysis enzymes, which split large molecules into smaller, observable units by combining with water. (Similarity, 2013) The hydrolysis of molecules becomes more effective by the release of specific enzymes that works at optimum pH in different regions of digestive tract. The three major GIG hormones are gastric from the stomach mucosa, secreting and collections (KC) from the duodenal mucosa. Gastric is released primarily in response to protein in the stomach, and its effects promote digestion of protein. Secreting is released in response to acid in the duodenum, and its effects will neutralize the acid. KC is released in response to fat in the duodenum, and its effects optimize conditions for fat digestion reactions. (Sherwood, 201 3) Digestion of carbohydrates begins in the mouth (salivary digestion), where the salivary glands (sublunary, subliminal or parroted) will secrete an amylase called fatality that begins the hydrolysis of complex polysaccharides: Plant extraterrestrial glycogen I Amylase Disaccharide(maltose, sucrose, lactose) I Fatality has an optimum pH of around 6. 8, which is roughly the pH found in the mouth. Protein digestion begins in the stomach (gastric digestion) where the enzyme pepsin splits proteins to shorter polypeptide chains containing amino acids. Secretion and activation of pepsin occurs as follows: Possession(chief cells) WHQL (parietal cells) I Pepsin I Besides activating possession, HCI provides the stomach a pH of 2, so the pepsin activity works at optimum level. For digestion of fat, pancreatic lipase reaction must be aided with the presence of bile salts as an emulsifier. Lipase is a water-soluble enzyme, and it is not effective alone to act on the large lipid droplets which are water insoluble. Bile salts emulsify by breaking the fat into smaller droplets so that lipase has a larger surface area for the hydrolysis of fats. The pancreas also aids digestion by secreting sodium bicarbonate. This compound provides a pH of around 7. 8 in the small intestine, which is optimal for the action of the pancreatic enzymes (Similarity, 2013). 2. 0.

What is the function of the mucous cells in the gastric pits? i. Protects the gastric mucosa against mechanical injury through its lubricating properties. Protects the stomach wall from self-digestion due to pepsin iii. Protects gastric lining against acid injury by neutralizing HCI secretions through its alkaline properties without interrupt the function of HCI in lumen. 6. 0. DISCUSSION All food ingested will go along through alimentary canal until it is secreted. Carbohydrates group will undergo digestion first along the way since the enzyme amylase that is responsible to digest the nutrient present in the saliva in the mouth. Besides having amylase to initiates chemical digestion, saliva also retests oral cavity, such as music. Music is a slippery globetrotting that protects the mouth from friction or erosion whilst undergo mastication (Campbell, et al. , 2008). Salivary amylase helps the carbohydrates digestion by hydrolysis complex polysaccharides to disaccharide and a-limit Dexedrine, that later will be broken down even further by other enzymes into incarcerations, a unit of nutrient that is observable (Sherwood, 2013). Tube 1 shows slowest reaction because there is no enzyme that can act upon starch or maltose present inside. The reaction will be different if there is implement enzyme present because enzyme functions as catalysts, agents that selectively speed up chemical reaction without being consumed by the reaction (Campbell, et al. , 2008). Hence, tube 1 will react as a control for the results in other tube in Table 1. In tube 2 that containing saliva, there is consistent reaction occur in starch but no in maltose. It is because saliva contain salivary amylase; enzyme that hydrolysis complex polysaccharides such as starch, consisting polysaccharides amylase (unbranded chain of glucose) and implementation (branched chain of glucose) into smaller polysaccharides (Sherwood, 2013). Since amylase is selectively reacting to polysaccharides, so it does not affect the reaction of maltose, which is a disaccharide. For tube 3 that containing saliva that is cooled, the reaction of starch is slower than tube 2, while the reaction of maltose is same as other previous tube that test on maltose which is no reaction. Enzyme works best at its optimum temperature that is 37 co which is the normal body temperature (Campbell Ferret, 2012). Any drops in the temperature will slower the enzymatic reaction like the cooled saliva containing amylase in tube 3. For tube 4, the pH environment is not suitable for amylase to take action. Fatality or amylase has an optimum pH of around 6. 8 (Similarity, 2013), so the acidic environment would inhibit the enzyme, resulted in very slow reaction of starch, and the no reaction in maltose like other tube. Protein group begins it digestive process in the stomach mantra, which containing enzyme pepsin that responsible in hydroplaning protein to peptide fragment, that soon undergo further breakdown by the act of other enzyme until it become nutrient unit that is observable which is amino acid (Sherwood, 2013). For activity 2, the rating of the results will be based on the intensity of the rupture of albumin textures. Based on Table 2, tube 1 has the most reaction of protein digestion compared to tube 2, 3 and 4. It is because enzyme pepsin works best at pH of 2 (Campbell Ferret, 2012), and tube 1 has the nearest pH preferable that is 3, being provided by the present of HCI. It can be observed that the part of the albumin is fragmented. Tube 2 has the second protein digestion because the pH environment is not too acidic for pepsin to act. Hence, there is less fragment resulted at the albumin in tube 2. Since there is no present of pepsin, the digestive process for tube 3 comes in third because there is no enzymatic reaction occurs although the pH reading for tube 3 is near to the optimum pH of pepsin activity.

The Most Poisonous Chemical Compounds

The Most Poisonous Chemical Compounds When you get right down to it, everything is poisonous. Water will kill you if you drink too much of it. Oxygen is a deadly poison, yet we need it to live. However, there are some chemicals that we are better off not encountering. Heres a list of the most poisonous chemicals known. Keep in mind, toxicity varies from one species to another (i.e., what may be poisonous for a mouse may be more/less poisonous to a human) and within a species (i.e., age, sex, genetics all affect susceptibility to a toxin).

Marketing - Research Paper Example This paper will look at marketing in general, as a process of moving products or services from the manufacturers or providers to the hands of their customers. Marketing Definition Marketing is a large process as Pride and Ferrell (3) defines it, encompassing quite a lot of processes. According to Pride and Ferrell (3) â€Å"marketing is the process of creating, distributing, promoting and pricing goods, services, and ideas to facilitate satisfying exchange relationships with customers to develop and maintain favourable relationships with stakeholders in the dynamic world.† According to this definition, marketing is includes more than just movement of goods from the plant to the customers. Marketing Process Sandhusen (2) defines the marketing process as the manner in which a firm seeks to identify the unfulfilled needs of the customers and coming up with various strategies to meet these needs. It does not involve just the process of moving products from the manufacturing plant to the customers. It involves the various processes that a marketing department goes through in order to come up with a marketing plan. Marketing process involves a number of steps, which include situation analysis in the market to identify the needs of the customers. ... Marketing mix decisions helps the firm to identify how to best get their products to the markets. Implementing the plan is the last step of the planning process where the firm ensures the laid down plans are followed by the teams supposed to implement the plan (Pride and Ferrell 195). Pride and Ferrell (3) state that â€Å"the essence of marketing is to develop satisfying exchanges from which both customers and marketers benefit.† This means that proper marketing is of benefit to both the firm and the customers. Marketing Mix When marketing a product, a firm need to develop an effective marketing mix which involves offering the right product, sold at the right price, in the right place and should offered using the most suitable promotion (Burrow and Jim 440-445). A number of conditions have to be met by a company seeking to create a successful marketing mix for its products. The features of the product that the company seeks to offer to the people must possess the right featur es which are desirable to the people. 4P’s of Marketing Price Gitman and Carl (295) points out that price is the most important integral of the marketing mix, since it is creates revenue for the firm. According to â€Å"pricing strategy is based on demand for the product and the cost for the producing it.† Thus, the price set should cater for all the expenses incurred by the product. Price is the only factor of the marketing mix which is not a cost, when compared with the others. The price of a product largely determines the value of sales made by a particular company. Price of a product or a service is largely affected by what the customers believe is the most appropriate value of the item on sale. If a company sets very high prices for its products so as to gain more profits, it

NET Framework Essay Example | Topics and Well Written Essays - 500 words

NET Framework - Essay Example The CLR is the foundation of the .NET framework. Basically, CLR acts as a virtual machine, providing an execution environment for the programs. The programmer can use Visual Basic, Jscript, and C # to write codes and the CLR manages the code written in these different languages at execution time. The other important features provided by CLR are memory management, thread management, garbage collection, exception handling and security. Residing above the operating system, it acts as a buffer for the programmer and handles and manages the execution of the applications without the programmer having to counter the technicalities and complexities of the operating system. On compilation of our programs using any of the .NET compatible high level languages, it does not get directly converted into the executable binary code but has to pass through an intermediate conversion state called MSIL or IL. This is done because IL is comprehensible by the CLR. Also that this IL makes the comparison and inter operability between codes of different high level languages possible as all the .NET compliant languages produce similar IL code.
