Ancient Civilization Essays - Ancient Near East, Civilizations

Ancient Civilization Describe Paleolithic and Neolithic cultures. What were the main characteristics of each? The Paleolithic Old Stone era began in about 40,000 - 10,000 B. C. The beginning of this period was marked by the first human hunter-gatherer societies. Hunting, fishing, and gathering of fruits and nuts were the main economic endeavors at the time. The responsibilities in these hunter-gathering societies were shared. The men of this period did the very dangerous hunting of large wild animals like bison and reindeer, while women gatherer fruits and nuts for an entire year. The small communities of 25-50 people came to consensus on decisions and ideas were shared. The extended family was core. Men and women both played a roll in child bearing. The people of this era lived in huts and caves. Caves were idealistic living quarters; they could be heated in the cold weather months and were cool in hot weather months. Caves were also good advantage points for observing prey. Caves were also the sites of representational art. Paleolithic cave paintings were of bison, horse, reindeer and mamm oths. Historians believe that art may have been the cave dwellers' attempts to control the environment through magic. Other representational art of this time included (Venus) figurines of women. The female figurines exaggerated the buttocks and breasts of women, perhaps in attempt to control fertility of women. Men spent a lot of time fashioning tools, like the javelin for hunting. The skilled craftsmanship of tools and the artists demonstrates at least a limited specialization of skills and division of labor, so these societies required organization in the villages. The desire to trade ideas and merchandise with other societies developed. The Neolithic New Stone era began sometime around 10,000 B. C. The beginning of this period was marked by the domestication of animals and plants. With men occupied in hunting, it may well have been females who first unraveled the secrets of agriculture. Humans specialized in the wild plants they collected and the animals they hunted. They began to learn how to control the environment in order to domesticate plants and animals. The domestication of animals perhaps started with dogs, which were useful in hunting. Then they learned to keep sheep, goats, chickens and cattle. Next came farming. They learned to grow wheat, barley, then legumes (beans). Craft specialization was evident, in addition to farming and shepherding, occupations in trading and accounting, iron working, clothing making, jewelers, artists and mining developed. The villagers mined copper (period was also known as Copper Age), gems, perhaps for pottery and hunting tools. Accountants were used for trade transactions. T echnological advancements came into use like the wheel and complex metal casting. In Europe, elaborate temple complexes and other monuments were built, which required complex mathematics. Also during the Neolithic period, religions developed. Gods and goddesses controlled everything. Gods and goddesses of the earth and fertility were worshipped. There was a strong urge to create cities near water. The organization and engineering that took place in this period is what lead humans to civilization. Discuss the causes of ancient civilization. Civilizations evolved in response to the need in the Neolithic communities for organization and engineering. Early civilizations were very complex. In early civilizations there is evidence of large and specialized labor forces, strong government, technology to control the environment, significant projects in art and thought and the invention of writing. As Neolithic communities grew, there was a strong urge to create cities near water. The first civilizations began in Mesopotamia between the Tigris and Euphrates Rivers and in the valley of the Nile River in Egypt around 3500 - 3000 B. C.. Large and efficient irrigation and drainage projects created channels, dikes, or dams to control floodwaters and to improve the fertility of the land. There was a need for social and economic hierarchies. The city was a society of strangers. There were single people as well as nuclear families in monogamous relationships. Civil rights came because you lived in a city. With individual freedoms came more responsibilities. There were five main social classes. The first class was the royal family, which marked the first form of government - monarchy. The position of king or queen was inherited. If there was not

Bay Of Pigs Invasion Essays - CubaUnited States Relations

Bay Of Pigs Invasion Essays - CubaUnited States Relations Bay Of Pigs Invasion The Bay of Pigs Invasion. The story of the failed invasion of Cuba at the Bay of Pigs is one of mismanagement, overconfidence, and lack of security. The blame for the failure of the operation falls directly in the lap of the Central Intelligence Agency and a young president and his advisors. The fall out from the invasion caused a rise in tension between the two great superpowers and ironically, years after the event, the person that the invasion meant to topple, Fidel Castro, is still in power. To understand the origins of the invasion and its ramifications for the future it is first necessary to look at the invasion and its origins. The Bay of Pigs invasion of April 1961, started a few days before on April 15th with the bombing of Cuba by what appeared to be defecting Cuban air force pilots. At 6 a.m. in the morning of that Saturday, three Cuban military bases were bombed by B-26 bombers. The airfields at Camp Libertad, San Antonio de Los Baos, and Antonio Maceo airport at Santiago de Cuba were fired upon. Seven people were killed at Libertad, and forty-seven people were killed at other sites on the island. Two of the B-26s left Cuba and flew to Miami, apparently to defect to the United States. The Cuban Revolutionary Council, the government in exile, in New York City released a statement saying that the bombings in Cuba were . . . carried out by 'Cubans inside Cuba' who were 'in contact with' the top command of the Revolutionary Council . . . . The New York Times reporter covering the story alluded to something being wrong with the whole situation when he wondered how the council knew the pilots were coming if the pilots had only decided to leave Cuba on Thursday after . . . a suspected betrayal by a fellow pilot had precipitated a plot to strike . . . .. Whatever the case, the planes came down in Miami later that morning, one landed at Key West Naval Air Station at 7:00 a.m. and the other at Miami International Airport at 8:20 a.m. Both planes were badly damaged and their tanks were nearly empty. On the front page of The New York Times the next day, a picture of one of the B-26s was shown along with a picture of one of the pilots cloaked in a baseball hat and hiding behind dark sunglasses, his name was withheld. A sense of conspiracy was even at this early stage beginning to envelop the events of that week. In the early hours of April 17th the assault on the Bay of Pigs began. As in the spirit of a movie, the assault began at 2 a.m. with a team of frogmen going ashore with orders to set up landing lights to indicate to the main assault force the precise location of their objectives, as w ell as to clear the area of anything that may impede the main landing teams when they arrived. At 2:30 a.m. and at 3:00 a.m. two battalions came ashore at Playa Girn and one battalion at Playa Larga beaches. The troops at Playa Girn had orders to move west, northwest, up the coast and meet with the troops at Playa Larga in the middle of the bay. A small group of men were then to be sent north to the town of Jaguey Grande to secure it as well. When looking at a modern map of Cuba it is obvious that the troops would have problems in the area that was chosen for them to land at. The area around the Bay of Pigs is a swampy marsh land area which would be hard on the troops. The Cuban forces were quick to react and Castro ordered his T-33 trainer jets, two Sea Furies, and two B-26s into the air to stop the invading forces. Off the coast were the command and control ship and another vessel carrying supplies for the invading forces. The Cuban air force made quick work of the supply ships, sinking the command vessel, the Marsopa, and the supply ship the Houston, blasting them to pieces with five-inch rockets.

(1) It was inevitable the U.S. and Russia sides would meet since the U.S. had been expanding west and Russia had been expanding east. Also, both empires were run differently. The American empire decentralized and comprised of states that could govern themselves with...

10 Argumentative Essay Topics on Medicalization as a Social Concept

10 Argumentative Essay Topics on Medicalization as a Social Concept If you need facts for your next essay on medicalization as a social concept, look at the items below: When medical problems are described in medical terms it is referred to as medicalization. This is a process by which non-medical situations are framed as something which requires medical treatment even if this is not true. This process can be detrimental to individuals because it causes otherwise normal human behavior to be rebranded as something like a medical condition. For many decades homosexuality was viewed as a mental illness. Even today one can find educational videos shown in public schools, and created by public schools, which emphasize the dangers of the homosexual medical illness. These videos talk heavily about how people who want to cultivate relationships with someone of the same sex suffer from a mental illness for which they must receive treatment. For many decades this belief, this medicalization of a simple biological aspect of humanity, one which is completely natural and has been observed in the animal kingdom since the beginning of time, led to a great deal of persecution and misunderstandings. It caused many people to believe that this normal human behavior was actually a severe medical condition. Bodily responses to regular processes such as inflammation or weight gain are viewed as problematic. This is another example of the medicalization of physical fitness. Because anyone who does exhibit a certain percentage of fat is viewed as unhealthy, this normal human state is now recognized as a medical condition. Now people, who are slightly overweight, are a regular target to diet and lifestyle suggestions and considered to have a medical condition for which medical treatment is required. This has led to a great deal of diet pills and eating supplements marketed to people of all ages. This has led to even more severe responses such as hypertension medication being given to children. People are immediately changing to the counter medications as though they were candy to treat simple ailments such as a swollen leg after a jog for a swollen shoulder muscle after lifting a heavy object. These are natural bodily responses to the everyday wear and tear that takes place on human bodies and yet the medicalization of such items has made them appear as though they were medical conditions which necessitate treatment. When the medicalization of any natural behavior becomes a socially accepted idea, it interferes with the regular processes of the human body. What might be a normal human function like converting simple and complex carbohydrates into sugars and therefore into insulin in the blood, become viewed as something detrimental or negative. Once it is viewed as a medical condition which requires medical treatment, people begin to take medications which interfere with the way the body works. This interference becomes permanent and leads to the additional reliance upon other medications which also interfere with natural behavior and human function. Rather than taking it upon oneself to monitor the food that is eaten, people will instead view their high blood sugar content as problematic in a single instance and take medication to stop the bodys production of insulin. While this is a natural occurrence that does take place in cases such as diabetes, many people today still bring this situation u pon themselves by taking medications. Simple illnesses which the body can fight naturally become medicalization gold. People will take antibiotics to help treat a simple infection which the body would have otherwise treated on its own. The more antibiotics are taken, and the more people fail to take them properly, the worse it is for the kidneys. When this happens the kidneys are no longer able to function properly which can result in renal failure. Any form of hormones taken by males or females are done so generally as a result of the medicalization of regular human behavior. And when this takes place it alters the body permanently. If the body generates a specific number of specific hormones each day, taking hormones in the form of medication will trick your body into believing that it has already generated the proper amount for that day. In doing so the body then cuts back on the total amount that it generates regularly. This means that if you stop taking your medicalized hormones your body will no longer produce the amount of hormones that it needs because it has been tricked into already thinking that it does. And when this happens the end result is that people have to stay on the useless medications for the long term which then leads to the same problem reoccurring and often in many other systems of the body simultaneously. The aging process has recently fallen victim to the medicalization of normal human processes. While aging was viewed as a regular event, something which was not only natural but beautiful, it is no longer so. Current social constructs of opinion leaders to believe that the aging process is bad and that all items associated with the aging process should be mitigated if not rectified. The result of this is that health care provides a variety of medications to treat the natural process of aging. All of these notions are unnecessary and yet people have to continue taking them for the rest of their lives once they start. Regular human emotions and reactions to their environment are natural human processes and yet thanks to the medicalization of health, many people now believe that being in touch with their emotions and responding in an emotional fashion to certain situation warrants unnatural behavior and medical treatment. In many cases depression is a mental state of being which can be controlled by the individual and which a perfectly natural response to certain situations is. Many times the emotional well-being of an individual impacted by changes in their life such as tragic events or hormones. And yet today these are viewed as negative things which must be rectified with pharmaceutical treatment. This leads to a series of negative ramifications in the form of secondary symptoms to the original medication prescribed. Individuals who are told that they suffer from depression because they are being sad about a few things in school are given medications. These medications cause side effects such as suicidal thoughts and weight gain. As a result people are being told that their weight gain must be rectified with additional medication. The suicidal thoughts must be halted immediately with another set of medications and both of these bring about new secondary symptoms and side effects the same as the original medication. This circle goes around and around for everybody who has ever been victim of medicalization. We hope these facts will find their place in your future essay.

Reciprocating Engines In-flight Fire Wildcountry Airways Ltd. De Assignment

Reciprocating Engines In-flight Fire Wildcountry Airways Ltd. De Havilland DHC-3 Otter C-FMEL 16 - Assignment Example The case under study was inclined towards a float-equipped DHC-3 (Otter). It had departed Ontario with six passengers and the pilot on board. At an approximate height of 2500 ft. above the sea level, the pilot managed to level the aircraft, hence configuring it for the cruise flight. Within a short period of time after such a level-off, he heard a form of popping sound and a notable loss of the engine power, while the whitish-grey smoke penetrated into the cabin (Sawyer, 1971). All the aircraft instruments showed normal engine operations. On the other hand, the fire warning unit failed to activate. The pilot thus assumed that the air-craft’s engine had been marred with a cylinder failure. The passenger who was seated in the front crew reported flames that were emerging from the right corner of the entire cockpit. The pilot hence tried to radio the Flight Service Station in order to seek for advice. Thick smoke bulged into the ultimate cabin thereby causing the respiratory distress and restricting visibility. The pilot then opened the left door so as to get a proper visual view and he luckily managed to land the aircraft while it was still on fire. It landed harder but lingered upright on floats. The passengers left through the main door with the life jackets on. The entire aircraft was hence consumed by the fire within almost immediately after landing. Being the last person to get out, the pilot suffered the second degree burns while the other passengers escaped with various injuries. This scenario hence called for an in-depth analysis and research of what might have ca used such a fire outbreak. All the findings were regarded to have been linked to the reciprocating engine. The reciprocating-engine powered transport aircraft offers essential public transport networks in most parts of the world. The only mishap as per the ATSB reports and

Nitric Oxide Production in Cytokine Activated Macrophages Lab Report

Nitric Oxide Production in Cytokine Activated Macrophages - Lab Report Example Apoptosis plays an important role in maintaining homeostasis in a number of physiological systems. NO can cause apoptosis to be induced in various cells including immune cells and tumor cells. Excessive and prolonged production of NO can trigger secondary damage of normal tissues. Therefore, the NO-secreting and activate macrophages needs to die or revert back to a resting state in order to prevent damaging of normal tissues (Tsujimoto, & Shimizu, 2005). Activation – induced apoptosis is the mechanism involving the removal of immunologically stimulated cells to help limit injury of normal tissues and to promote immunologic tolerance. IL-2, one of the major cytokine, which is secreted from an activated lymphocyte during inflammatory or immune responses, can trigger various immune cells such as macrophages and lymphocytes to produce a plethora of cytokines including TNF-ÃŽ ², TNF-ÃŽ ±, IL-1ÃŽ ², IL-6, and IL-1ÃŽ ±. (Tsujimoto, & Shimizu, 2005). These cytokines can potentially in duce responding cells for instance macrophages to synthesize and produce high NO nitrite levels from l-arginine through the action of the enzyme called inducible nitric oxide synthase. In this study, the focus was ascertaining the impact of the cytokines on the rate of synthesis and production of NO from macrophages (Hu, & Brindle, 2005). In relating the optical density to the levels of nitrite, volumes of standardized sodium nitrite solution 50Â µg/ml) was added to culture medium. It was observed that increase in the volume of Volume of 50Â µg/ml standard added to 0.5ml culture medium caused a corresponding increase in Optical density (OD) as depicted in table 01 and graph 01. The results of this experiment indicate that cytokines have an impact on the production of NO by macrophages. The higher the number of cytokines used the higher the Optical density values hence the higher production of NO. The value for OD was lowest (OD=0.057)

Nutrition and the relationship to athletic performance Essay

Nutrition and the relationship to athletic performance - Essay Example Proper eating habits play an integral role in fueling the body to operate effectively. Even the well conditioned and best trained athlete will have a hard time performing at peak level if improperly nourished. Also, it is essential for the athlete to understand that a balanced diet is critical not only for athletic excellence but also to maintain tissues that have been damaged during physical activity and, more importantly, for the young athlete who will need the additional nutrients to allow for continued growth and bone development. Carbohydrate is the most efficient and recommended source of glucose that the body needs to produce energy. Once ingested, the body converts carbohydrates into glucose that will give the athlete power and stamina to endure high intensity, short duration activities. Excess glucose, called glycogen, is absorbed in the liver and muscle tissues for later use. If the body lacks sources of carbohydrates, the body is forced to convert fat and protein into energy resulting in poor performance and increased fatigue. Carbohydrates are divided into two groups, the simple and complex carbohydrates. The simple carbohydrates, sometimes also referred to as the "bad carbs", are commonly found in refined or packaged food such as sugar, candy, chips, milk, honey and, fruit juices. Although, these types of carbohydrates are easily digested, they lack essential vitamins and nutrients that can normally be found in food sources containing complex carbohydrates. They are so-called because, unlike the simple carbohydrates, complex carbohydrates take longer to digest but it brings with it the essential vitamins and minerals that the body needs on a daily basis. This type of carbohydrate is commonly found in fresh fruits and vegetables, oatmeal, rice, bread, cereal, pita, pretzel, muffins and, pasta dishes. Although there are many recommendations on the amount of carbohydrate to be taken daily, most experts agree that carbohydrate consumption should consist of at the most two-thirds (2/3) of any given meal, roughly 3 to 4 times of a persons' weight in pounds. This means, for example, a person weighing 160 pounds should consume about 480-640 grams of carbohydrate everyday to maintain his energy level. And as exercise and training increase, carbohydrate consumption should be increased appropriately. According to the studies made by Leslie Bonci M.P.H., R.D., the following increase in carbohydrate intake is recommended for the active athlete: 3 grams/lb body weight for 1 hour of training 4.5 grams/kg body weight for 2 hours training 5 grams/kg body weight for 3 hours training, and 6 grams/kg body weight for 4+ hours of training (Bonci, n.d.a, Carbohydrate Needs section, par.1) Another technique used by endurance athletes, like bicyclers, swimmers and long-distance runners is "carbohydrate loading" or commonly referred to as
