Analysis of Vegetables Essay Example for Free

Analysis of Vegetables Essay For example, calcium and phosphorus are required for the formation of bones and teeth deficiency of these causes the decay of teeth and bones. Deficiency of iron causes anemia. Lack of iodine causes goiter. So it is necessary that the food we eat be selected carefully. Besides wheat, rice and milk, fruits and vegetables form an important part of balanced diet. They contain minerals, carbohydrates and vitamins. We are advised by doctors to include more vegetables and fruits in our diets, Therefore, study could be undertaken to investigate the constituents of various fruits and vegetables. OBJECTIVE OF PROJECT To plan for the balanced diet, knowledge of various ingredients of fruits and vegetables is necessary. In this project, we aim to have knowledge about the contents of different fruits.

The Natural History of Mahogany :: Botany

The Natural History of Mahogany Swietenia macrophylla and S. humilis are referred to as Mahogany, a tropical evergreen or deciduous tree that can attain heights of 150 feet. Mahogany is a member of the Meliaceae, which includes other trees with notable wood for cabinet making. Swietenia macrophylla is world renowned for its beautifully grained, hard, red-brown wood. It has been harvested since 1500 A.D. for its wood, with large branches being in higher demand than the trunk. This is due to the closeness of the grain in the branch's wood. Mahogany is used for furniture, fixtures, musical instruments, millwork, cars, ships, boats, caskets, airplanes, foundry patterns, veneer, and plywood (Hill, 1952). In Costa Rica, the only population of Mahogany exists in the Guanacaste-Puntarenas region where the tropical dry forests occur. Both of the species' ranges overlap in this region, with Bigleaf Mahogany, S. macrophylla, extending from the Bolivian Amazon up the Atlantic and Gulf Coast to Mexico, while Pacific Coast Mahogany, S. humilis, ranges from Mexico down the Pacific Coast to 9 degrees N in Costa Rica. The two species defy taxonomy and interbreed to form a hybrid. The hybrid grows quicker than either parent species, has intermediate characteristics, and high quality wood (Everett, 1982). Mahogany is never very abundant, even in undisturbed forests, with a density of only one tree per hectare. This, along with the destruction of tropical forests has added to the growing scarcity of Mahogany. The normal habitat of S. macrophylla and S. humilis is lowland tropical or subtropical forest, with average annual rainfall totals between 1 and 2.5 meters. If the tree is in tropical moist or wet forests, it will lose its leaves briefly. However, in tropical dry forests, such as Guanacaste, the tree will be leafless for a few months. Mahogany has pinnately-compound leaves composed of 4 to 6, ovate-acuminate leaflets. The leaf is often without a terminal leaflet. The bark has vertical scales, giving it the appearance of Silver Maple or White Oak bark. The flowers are imperfect, with greater numbers of male than female flowers. Each flower is small, yellow-white, and borne in a panicle at the end of the dry season. The fruits of the Mahogany will ripen during January-March in the Guanacaste region of Costa Rica. They are 4 to 6 inch woody capsules which contain up to 40 wind-dispersed seeds, similar to those of an Ash tree.

Maps in Your Mind Essay

Reasons for Tolman to carry out the study were to demonstrate that complex internal cognitive activity could be studied in rats, not only in humans, and that these mental processes could be studied without the necessity of observing them directly. The theoretical propositions which this research is based on were two 2 modifications to the prevailing view that Tolman proposed. One was that the true nature and complexity of learning could not be fully understood without an examination of the internal mental processes that accompany the observable stimuli and responses. The second was that even though internal cognitive processes could not be directly observed, they could be objectively and scientifically inferred from observable behavior. The method Tolman used were two studies which clearly demonstra6ted his theoretical propositions. The first was called â€Å"The Latent Learning† experiment, where rats were divided into 3 groups. The first of the 3 groups was Group C, control group, which was exposed to a complex maze using the standard procedure of one run through the maze each day with a food reward at the end of the maze. Second was Group N, received no reward, which was exposed to the maze for the same amount of time each day but found no food and received no reward for any behavior in the maze. Last was Group D, received a delayed reward, which was treated exactly like group N for the first 10 days of the study, but then on day 11 and the remainder of the experiment found food at the end of the maze. The results to the first study were that the rats in groups N and D did not learn much of anything about the maze when they were not receiving any reward for running through the maze. Group C rats learned the maze to near-perfection in about two weeks. But rats in Group D had found out a reason to run the maze and that was food. They had learned the maze in about 3 days (day 11 to day 13). The only possible explanation for these findings was that during those 10 days when the rats were wandering around in the maze, they were learning much more about the maze than they were showing. Tolman explained â€Å"Once they knew they were to get food, they demonstrated that during the preceding non-reward trials, they had learned where many of the blinds were. They had been building up a map and could utilize it as soon as they were motivated to do so.† Now the second study was called â€Å"Spatial Orientation† experiment. This experiment was designed to show that rats trained in a maze actually know the location of the food reward relative to their starting position even if the elements of the maze are changed, or even removed. First rats learned to run the simple maze, where they entered the maze at the start, then run across a round table and into the path leading to the food at the end. This was a relatively simple maze and no problem for the rats and learned it to near perfection in 12 trials. The maze was changed into a sunburst pattern, now when the rats tried their usual rout they found it blocked and returned to the round table. There the rats had a choice of 12 possible alternate paths to try to get to where the food had been in the previous maze. Results for the second study showed that the rats had frequently chose path 6, which ran about 4 inches from where the food had been placed in the previous maze. Here, Tolman was expanding his theory beyond the notion that rats, and potentially other organisms including humans, produce cognitive maps of the route from point A to point Z. He was demonstrating that the maps that are produced are not mere strip maps represented as A to B to C and so on, to Z, but are much broader, comprehensive or conceptual maps that give organisms a cognitive lay of the land. The significance of Tolman’s study was that Tolman theorized that comprehensive maps of our social environment are advantageous to humans, while narrow; strip like maps can lead to negative human conditions such as mental illness or prejudice and discrimination. His reasoning was based on findings related to the studies described earlier indicating that when rats were over motivated or over frustrated they tended to develop very narrow maps and were less likely to acquire the comprehensive cognitive mapping skills of the rats described in his studies.

Greed Is All Right, By The Way - 3072 Words

Ivan Boesky at an audience of students at the University of California, Berkeley once stated, â€Å"Greed is all right, by the way. I think greed is healthy. You can be greedy and still feel good about yourself (Homans, 2012, p.1)(Kay, 2003, p.1).† Greed was what lead Boesky to Insider Trading and ultimately huge illegal profits; the scam he created was hidden in plain sight. Boesky wanted everyone to believe that he was doing the world a service but he was actually stealing (Homans, 2012, p.1). According to the Encyclopedia of White-Collar Crime, insider trading is a securities fraud that involves the purchase and sale of a security while the purchaser has trusted or privileged information about the security unannounced to the public. The†¦show more content†¦Debra Ross in the Encyclopedia of White-Collar Crime defined arbitrage as: â€Å"(1) a transaction that generates a risk-free profit; (2) a leveraged speculative transaction; and (3) the activity of engaging i n either of the above two forms of arbitrage transactions (p. 31).† Boesky’s forte was trading stock in companies aimed for an acquisition or merger, and this type of enterprise is legal as long as the trade was based on public information of looming acquisitions. This case study will explore the life and crime of Ivan Boesky and those individuals who helped him. Boesky’s journey from a college dropout to a Wall Street executive is of a man obsessed with money and the lifestyle that it afforded. In the end, greed didn’t prevail, and many lives, laws, enterprises were impacted, often for the better. Ivan Boesky was born 1937 in Detroit where his father owned several bars, restaurants and delicatessens (Meserve, 2012). During his child hood, Boesky and his family lived in a nice Tudor-style house in an upper-middle-class neighborhood. Boesky’s parents were immigrants from Russia. Boesky worked hard in high school selling ice cream from a truck and wo uld often break curfew of 7 pm imposed by his license. Boesky did attend Cranbrook for a couple years, but he did not graduate. Although Boesky’s did not get good grades, he was a fantastic wrestler; winning the school’s
