Online courses - Essay Example not hold a similar incentive as customary degrees do, however this theory will attempt to take a gander at the opposite side of online degrees as having a similar incentive as the ordinary degrees. Online schools, much the same as their ordinary study hall universities need to follow the set down rules in offering their degree, online universities simply like traditional ones. They need to encourage the compulsory units and subjects in a specific degree program, they need to follow the specified courses of events and evaluating of the understudies must be done at ordinary interims likewise the traditional schools do (Koontz, Li and Compora 38). In online degree programs, the subjects are instructed by an educator and not a customized robot as some might suspect, class notes are sent by the instructor to the understudies through email. The instructor cooperate with his understudies online through different ways, for example, online video talks and message sheets, the tests are done on the web and they are reviewed by a genuine educator. In a review directed to decide the view of bosses toward online degrees, in 2001 just twenty-nine percent of businesses said they would not recruit understudies with online degrees. The rest seventy-one percent said they wouldn't fret the whether the degree was regular or online as long it was from an authorize organization of learning and the representative had obtained the applicable aptitudes. A few bosses are currently leaning toward online degree holder to the traditional degree holders as the online degree holders are seen to have certain qualities such self starters, they have self-restraint and can comply with time constraints. In the workforce, online degrees are esteemed as an incredible resource since they demonstrate the holder was inventive enough to have the option to finish the program online effectively (Palloff, Pratt and Palloff 18). An examination led by the United States branch of instruction in 2009 found that the understudies who showed improvement over the individuals who went to the traditional

What Parents Can Do to Help Teens Cope With Anger

What Parents Can Do to Help Teens Cope With Anger Emotions Print How Parents Can Help Troubled Teens Cope With Anger Helping Troubled Teens Understand and Express Angry Feelings By Kathryn Rudlin, LCSW Medically reviewed by Medically reviewed by Steven Gans, MD on August 05, 2016 Steven Gans, MD is board-certified in psychiatry and is an active supervisor, teacher, and mentor at Massachusetts General Hospital. Learn about our Medical Review Board Steven Gans, MD Updated on January 13, 2020 Comstock / Getty Images More in Psychology Emotions Psychotherapy Basics Student Resources History and Biographies Theories Phobias Sleep and Dreaming Many teens get into trouble because of an inability to appropriately discharge feelings of intense anger. Teens become angry for various reasons and express these feelings in a multitude of ways, but all have in common the struggle of experiencing a painful emotion and not knowing how to manage it. Inappropriate expressions of anger can have serious consequences for troubled teens, but most have the capacity to learn better ways of coping. Heres what parents can do to help. Understand Your Teens Anger Anger is an emotion that is quite often challenging for teens and at times can be overwhelming. A teen who doesnt know how to cope with angry feelings may feel a strong desire to act directly on these feelings, even when it puts them or others at risk. Underneath anger are often difficult emotions, such as hurt, frustration or sadness that a teen tries to avoid or isnt aware they are feeling. When a troubled teen is acting out their anger in problematic ways, it can often be helpful for the teen to get in touch with what is driving this emotion and how to express and discharge it in healthier ways. Why Anger Isnt Really the Problem Feeling angry isnt really the problem for most teens. Although anger can produce significant physical and emotional discomfort, it is an appropriate response to being hurt or feeling frustrated or powerless. Anger is a real and important emotion to experience and be aware of; its the expression of this emotion that becomes a struggle for many troubled teens. Much like a toddler who has a temper tantrum when upset or unhappy, a teen experiencing similar emotions often attempts to deal with anger by discharging it onto other people or objects. Many parents are forced to deal with teens driven by anger who punch holes in the wall, get into fights or are mean to others or themselves. Strategies to Help Teens Safely Express Anger The challenge in helping explosive teens is keeping them safe while they learn ways to recognize anger and deal with it more constructively. There is a great deal that parents can do to help an angry teen learn ways to successfully cope with anger, heres how to help your teen deal with their anger: Participate in physical activities. The impulse to do something physical when feeling angry is strong in most teens. Involvement in sports and other exercise helps in expressing anger on a regular basis.Hit a punching bag. Teens need safe ways to get their anger out, a punching bag works well, so does hitting a pillow repeatedly, or using a foam padded bat.Take a time-out. When anger escalates teens may need time alone to calm down and yell, cry or whatever is needed so they stay safe and others are not negatively impacted.Get into music. Popular with most teens, music works well to help teens identify and express feelings of anger, whether through singing, dancing or playing along with songs filled with rage.Identify triggers to anger. The better your teen can make the connection between what leads to angry outbursts, the more control theyll have in expressing this emotion.Creatively express angry feelings. Both writing and drawing can be used effectively by teens to express and und erstand anger. When a troubled teen still isnt able to get a handle on their anger its time to consider getting professional help to get to the root of their anger and learn ways to manage these feelings. Expressive therapies help teens express anger, anger management groups provide an opportunity for teens to learn from each other, individual therapy provides a safe place to explore this difficult emotion. Keep in mind that uncontrolled anger is sometimes associated with mental health disorders in teens, so make sure to get professional help for your teen if their anger continues to be a problem.

A Short Note On Diabetes Mellitus Research Paper - 2143 Words

Diabetes Mellitus Research Paper For: Annabelle Anglo VN FT030 – Term 3 3/16/2015 Pete Sanford LVN FT030 Diabetes Mellitus (â€Å"DM†) is one of the most serious and widespread non-infectious diseases. Per Porter (2013), DM has a long history, tracing back Egypt over 3,500 years ago when Egyptian doctors used ants to test for the â€Å"sweet urine† disease. According to Statistics about Diabetes (2015) over 29 million Americans suffer with DM, including about 12 million (26%) of Americans over age 65. The ADA estimates that about 234,000 deaths in the U.S. are attributable to DM. SECTION 1 -- PATHOPHYSIOLOGY Non-Insulin Dependent Diabetes Mellitus (NIDDM), often called â€Å"Type 1 Diabetes†.

If so, antioxidant therapy (i.e., adding fruits, plants, vitamins and other supplements to patients’ diet) reduces the development of IDDM and its complications, including cardiomyopathy, retinopathy and neuropathy. SECTION 2 -- SIGNS AND SYMPTOMS OF DIABETES MELLITUS (â€Å"DM†) NIDDM signs and symptoms come on rapidly because of a triggering event – a viral infection or other stress to the body. In contrast, IDDM signs and symptoms are mild and most patients will not recognize them until the hyperglycemia creates significant damage to the body, especially to the blood vessels, liver and kidneys. Often the first sign is nocturia, where patients are irritated by having to void several times each night. Per Medline Plus (2015), the early symptoms are: increased urination, thirst and hunger (â€Å"the 3 P’s† – polyuria, polydipsia and polyphagia), skin or renal infections that occur more frequently and heal more slowly,). NIDDM patients are typically less than 20 years old and have weight loss despite eating more. IDDM patients typically are over 45 years old and complain of lack of energy, blurry vision and pain or numbness. See chart below from Woman’s Healthy Fitness Tips (2015).

White Men s Exploitation Of Black Women s Sexuality

Through the antebellum period, white men’s exploitation of black women’s sexuality created an assumption that black women were driven by lust and sexual promiscuity. This false stereotypical assumption by the slave south held black women captive by the patriarchal society of plantations. This gave white males grounds for sexual activity with their enslaved women. Through a slave women’s â€Å"lustfulness,† the antebellum period, (the years prior to the Civil War and between the 1830’s and 1860’s), saw an influx of bi-racial and multi-racial slave offspring as an effect of the Fancy Trade and slave breeding practices.

The domestic slave trade within the United States did not begin with the abolishment of the Trans-Atlantic sl ave trade in 1808, instead they overlapped for a number of years. The domestic slave trade however, grew in dramatic ways during the antebellum period. Slaves were forcefully moved from their families and sold from the old South states (Delaware, Maryland, Virginia, and the Carolina’s) to the new South territories and states (Mississippi, Texas, Alabama, Louisiana, and Georgia). The value of slaves greatly rose during the antebellum period because of the domestic slave trade and the success of a major cash crop â€Å"King Cotton.† From 1832 to 1837, slave prices steadily rose to around six hundred and fifty dollars per slave from below three hundred in 1831. However, the â€Å"Panic of 1837† caused a depression until the three-fold increase in 1843 with the worldwide demand for the New South to produce more cotton. From 1843, prices steadily climbed

Comparison of Batteries Free Essays

Lead Acid Cell vs. Button Cell Lead acid cells were invented in 1859 by the French Physicist Gaston Plante, and are the oldest types of rechargeable batteries. These types of batteries typically weigh at 5kg, but can range from half a kilogram to over 30 kilograms on the consumer market. We will write a custom essay sample on Comparison of Batteries or any similar topic only for you Order Now Though their chemistry means a very low energy-to-weight and energy-to-volume ratio in comparison to other modern batteries, their ability to supply high surge currents means that the cells maintain a large power-to-weight ratio. This makes them highly desirable for use in large appliances such as motor vehicles, which require the high current provided by this type of battery. In comparison, Button cells are much smaller than lead acid cells. Button cells are shaped as small, squat cylinders usually 5 to 22mm in diameter and between 1 to 6mm in height and weigh little over several grams. The voltage and current produced by these batteries are small and steady, and these properties make them very suitable for powering small portable electronic devices such as wrist watches, pocket calculators, hearing aids, and sometimes pacemakers. These batteries are usually not rechargeable, and last a long time, though lifespan depends on chemical composition and use. Chemistry Lead acid calls use a chemical reaction in order to produce a voltage between the output terminals. The battery contains two plates, and the discharge process is driven by the conduction of electrons from the negative plate back into the cell at the positive plate. All lead acid sells use Lead Sulfate in their reactions. These chemicals were originally contained as a liquid, but a technique has now been developed in which a gel electrolyte is used, preventing leakage. Negative plate reaction: Pb(s) + HSO? 4(aq) PbSO4(s) + H+(aq) + 2e- Positive plate reaction: PbO2(s) + HSO? 4(aq) + 3H+(aq) + 2e- PbSO4(s) + 2H2O(l) Overall reaction: Pb(s) + PbO2(s) + 2H2SO4(aq) 2PbSO4(s) + 2H2O(l) Button cells are single cells, and are Primary cells, being not rechargeable. Button cells have both an Anode and Cathode separated by a separator contained within a metal â€Å"can†. Common anode materials are zinc or lithium, and there are a range of cathode materials, including manganese dioxide, silver oxide, and cupric oxide. Of notable mention is the mercuric oxide button cell, which was banned due to the toxicity and environmental hazard of mercury. Reaction between silver oxide (cathode) and zinc (anode): Zn + Ag2O ZnO + 2Ag These batteries are dry batteries, and are created with the ideal of a long lifetime. As such, they rarely leak if ever, and boast a steady electricity production over a long period of time. Both Lead acid cells and button cells rely on chemical reactions for the production of their energy. However, where a lead-acid cell would typically use an anode and cathode within a liquid or gel medium, button cells use solid anode and cathodes which react with each other through a separator. This reflects their uses; where the chemistry of a lead acid battery allows it to produce large amounts of electricity in surges as needed to start appliances such as motor vehicles, the chemistry of Button cells allows for a slow and steady release of small amounts of charge. Cost and Practicality As was reflected upon under the chemistry subtitle, the batteries have been designed, and retain their designs, to specifically fit their uses. Though the size of the lead acid batteries does not allow for the powering of small portable devices such as watches, it maintains its usefulness in larger appliances and uses such as motor vehicles, which require a large amount of electrical energy to start up, but does not require a steady flow of energy. This is reflected in the property of these batteries being able to release large surges of energy. As these are designed for long use and provide large power, the cost for these are quite high, ranging from $100 to $300 each. In comparison, the button cell battery is used for very small applications such as wrist watches and hearing aids. This is reflected in their small, convenience, and ability to provide a long lasting, steady flow of energy. However, this means that they are unable to supply large amounts of energy at a time, and are therefore unfit for use in industry and larger appliances such as motor vehicles. The cost of these batteries is much cheaper than that of the large, lead acid batteries, rarely coming up to above a few dollars. Impact on Society Batteries have had a large impact on society since their invention. In particular, lead acid batteries were among the first to be invented. These batteries have had a major impact on society; They have allowed for the powering of motor vehicles, which have become a major component in the lives of many living in developed cities. Though an older model of battery, these batteries continue to hold significant impact on society even today. In comparison, button cells power small, handheld portable appliances such as watches and hearing aids. This is asignificant difference from the impact of lead acid batteries. However, both batteries have impacted the life of many in developed societies, generally making life easier, and more convenient for all. Environmental impact Lead acid batteries are extremely hazardous to the environment. Lead is a hazardous metal, and poisonous to both environments and animals, and humans are not excepted. Though the use of lead in batteries is usually very controlled, the production of it is not; of three plants in Australia, two have required strict non-residential zones of 2-3 km. This implies that though all safety precautions are being taken, there is still a danger of contamination and danger to the environment. In comparison, button cells are much safer. Though non rechargeable, their recyclability means the mining of the metals used in batteries is reduced to a minimum. However, the environmental impact of these materials is determined by the actual materials used. This was reflected upon in the past, when mercuric oxide batteries were banned for the toxicity and environmental damage caused by mercury.

The Return of the Prodigal Son Analysis Essay Example

The Return of the Prodigal Son Analysis Paper Analysis of The Return of the Prodigal Son by Guercino The Return of the Prodigal Son By Guercino was painted from the years 1654-55. Its medium is oil on canvas and is 611/4 x 571/2 inches. This piece of art is located at the Timken Museum in Balboa Park. Guercino painted this piece of art on seven different instances. All having the same emotion and feel but he felt the need to repaint the biblical parable multiple times. Guercino paints so much passioninto his pieces and it is very well reflected in this one particular work of art. In GuercinosReturn of the Prodigal Son, the artist uses chiaroscuro, a baroque style, dynamic coloring, and uses the influences of Caravaggioto contrast the humility of human existence and depict a further serene theme from this tale of Luke. Born with the name Giovanni Francesco Barbieri, later known as Guercino (meaning squint in Italian), was an Italian Baroque painter and draftsman. He seemed , to a large extent, to have been self taught but somehow quickly established an international reputation as one of the finest painters in Italy. For most of his life he chose to remain in his native town of Cento, nearby Bologna. Because of his unwillingness to travel, his late, uneventful life, didnt seem to be as documented as his earlier years. During his younger years, however, he took a two year work related trip to Rome, where he completed the vast altar piece of the Burial and Reception into Heaven of St. Petronilla. When returning back from Rome to his local town of Cento, his reputation was very high indeed and not solely in Italy. He would have nobles like King Charles I of England, Louis XIII of France, and even Philip IV in Madrid attempt to lure Guercino to paint for them. Guercino, though, had no wish to travel. H e was then visited by princes, cardinals, dukes, and many nobles and it is significant that they went to him and not he to them.

Philosopher Hypatia of Ancient Alexandria

Philosopher Hypatia of Ancient Alexandria Known for: Greek intellectual and teacher in Alexandria, Egypt, known for mathematics and philosophy, martyred by Christian mob Dates: born about 350 to 370, died 416 Alternate spelling: Ipazia About Hypatia Hypatia was the daughter of Theon of Alexandria who was a teacher of mathematics with the Museum of Alexandria in Egypt. A center of Greek intellectual and cultural life, the Museum included many independent schools and the great library of Alexandria. Hypatia studied with her father, and with many others including Plutarch the Younger. She herself taught at the Neoplatonist school of philosophy. She became the salaried director of this school in 400. She probably wrote on mathematics, astronomy, and philosophy, including about the motions of the planets, about number theory and about conic sections. Accomplishments Hypatia, according to sources, corresponded with and hosted scholars from other cities. Synesius, Bishop of Ptolemais, was one of her correspondents and he visited her frequently. Hypatia was a popular lecturer, drawing students from many parts of the empire. From the little historical information about Hypatia that survives, it is surmised by some that she invented the plane astrolabe, the graduated brass hydrometer, and the hydroscope, with Synesius of Greece, who was her student and later colleague.  The evidence may also point to simply being able to construct those instruments. Hypatia is said to have dressed in the clothing of a scholar or teacher, rather than in womens clothing. She moved about freely, driving her own chariot, contrary to the norm for womens public behavior. She was credited by the surviving sources as having political influence in the city, especially with Orestes, the Roman governor of Alexandria. Hypatias Death The story by Socrates Scholasticus written soon after Hypatias death and the version written by John of Nikiu of Egypt more than 200 years later disagree in considerable detail, although both were written by Christians.  Both seem to be focused on justifying the expulsion of the Jews by Cyril, the Christian bishop, and on associating Orestes with Hypatia. In both, Hypatias death was a result of a conflict between the Orestes and Cyril, later made a saint of the church. According to Scholasticus, an order of Orestes to control Jewish celebrations met with approval by Christians, then to violence between the Christians and the Jews. The Christian-told stories make it clear that they blame the Jews for the mass killing of Christians, leading to the banishment of the Jews of Alexandria by Cyril.  Cyril accused Orestes of being a pagan, and a large group of monks who came to fight with Cyril attacked Orestes. A monk who injured Orestes was arrested and tortured.  John of Nikiu accuses Orestes of inflaming the Jews against the Christians, also telling a story of the mass killing of Christians by Jews, followed by Cyril purging the Jews from Alexandria and converting the synagogues to churches.  Johns version leaves out the part about a large group of monks coming to town and joining the Christian forces against the Jews and Orestes. Hypatia enters the story as someone associated with Orestes and suspected by the angry Christians of advising Orestes not to reconcile with Cyril.  In John of Nikius account, Orestes was causing people to leave the church and follow Hypatia.  He  associated her with Satan and accused her of converting people away from Christianity. Scholasticus credits Cyrils preaching against Hypatia with inciting a mob led by fanatical Christian monks to attack Hypatia as she drove her chariot through Alexandria. They dragged her from her chariot, stripped her, killed her, stripped her flesh from her bones, scattered her body parts through the streets, and burned some remaining parts of her body in the library of Caesareum.  Johns version of her death is also that a mob for him justified because she beguiled the people of the city and the prefect through her enchantments stripped her naked and dragged her through the city until she died. Legacy of Hypatia Hypatias students fled to Athens, where the study of mathematics flourished after that. The Neoplatonic school she headed continued in Alexandria until the Arabs invaded in 642. When the library of Alexandria was burned, the works of Hypatia were destroyed.  That burning happened primarily in Roman times.  We know her writings today through the works of others who quoted her even if unfavorably and a few letters written to her by contemporaries.

Washington Naval Disarmament Treaty

Washington Naval Disarmament Treaty The Washington Naval Conference Following the end of World War I, the United States, Great Britain, and Japan all commenced large-scale programs of capital ship construction. In the United States, this took the form of five new battleships and four battlecruisers, while across the Atlantic the Royal Navy was preparing to build its series of G3 Battlecruisers and N3 Battleships. For the Japanese, the postwar naval construction began with a program calling for eight new battleships and eight new battlecruisers. This building spree led to concern that a new naval arms race, similar to the pre-war Anglo-German competition, was about to begin. Seeking to prevent this, President Warren G. Harding called the Washington Naval Conference in late 1921, with the goal of establishing limits on warship construction and tonnage. Convening on November 12, 1921, under the auspices of the League of Nations, the delegates met at Memorial Continental Hall in Washington DC. Attended by nine countries with concerns in the Pacific, the principal players included the United States, Great Britain, Japan, France, and Italy. Leading the American delegation was Secretary of State Charles Evan Hughes who sought to limit Japanese expansionism in the Pacific. For the British, the conference offered an opportunity to avoid an arms race with the US as well as an opportunity to achieve stability in the Pacific which would provide protection to Hong Kong, Singapore, Australia, and New Zealand. Arriving in Washington, the Japanese possessed a clear agenda that included a naval treaty and recognition of their interests in Manchuria and Mongolia. Both nations were concerned about the power of American shipyards to out-produce them if an arms race were to occur. As the negotiations commenced, Hughes was aided by intelligence provided by Herbert Yardleys Black Chamber. Operated cooperatively by the State Department and US Army, Yardleys office was tasked with intercepting and decrypting communications between the delegations and their home governments. Particular progress was made breaking Japanese codes and reading their traffic. The intelligence received from this source permitted Hughes to negotiate the most favorable deal possible with the Japanese. After several weeks of meetings, the worlds first disarmament treaty was signed on February 6, 1922. The Washington Naval Treaty The Washington Naval Treaty set specific tonnage limits on the signees as well as restricted armament size and expansion of naval facilities. The core of the treaty established a tonnage ratio that permitted the following: United States: Capital Ships - 525,000 tons, Aircraft Carriers - 135,000 tonsGreat Britain: Capital Ships - 525,000 tons, Aircraft Carriers - 135,000 tonsJapan: Capital Ships - 315,000 tons, Aircraft Carriers - 81,000 tonsFrance: Capital Ships - 175,000 tons, Aircraft Carriers - 60,000 tonsItaly: Capital Ships - 175,000 tons, Aircraft Carriers - 60,000 tons As part of these restrictions, no single ship was to exceed 35,000 tons or mount larger than 16-inch guns. Aircraft carrier size was capped at 27,000 tons, though two per nation could be as large as 33,000 tons. In regard to onshore facilities, it was agreed that the status quo at the time of the treatys signing would be maintained. This prohibited the further expansion or fortification of naval bases in small island territories and possessions. Expansion on the mainland or large islands (such as Hawaii) was permitted. Since some commissioned warships  exceeded the treaty terms, some exceptions were made for existing tonnage. Under the treaty, older warships could be replaced, however, the new vessels were required to meet the restrictions and all signatories were to be informed of their construction. The 5:5:3:1:1 ratio imposed by the treaty led to friction during negotiations. France, with coasts on the Atlantic and Mediterranean, felt that it should be permitted a larger fleet than Italy. They were finally convinced to agree to the ratio by promises of British support in the Atlantic. Among the main naval powers, the 5:5:3 ratio was badly received by the Japanese who felt they were being slighted by the Western Powers. As the Imperial Japanese Navy was essentially a one-ocean navy, the ratio still gave them a superiority over the US and Royal Navy which had multi-ocean responsibilities. With the treatys implementation, the British were forced to cancel the G3 and N3 programs and the US Navy was required to scrap some of its existing tonnages to meet the tonnage restriction. Two battlecruisers then under construction were converted into the aircraft carriers USS Lexington and USS Saratoga. The treaty effectively stopped battleship construction for several years as the signatories attempted to design ships that were powerful, but yet still met the agreements terms. Also, efforts were made to build large light cruisers that were effectively heavy cruisers or that could be up-converted with bigger guns in wartime. In 1930, the treaty was altered by the London Naval Treaty. This, in turn, was followed by the Second London Naval Treaty in 1936. This last treaty was not signed by Japanese as they had decided to withdraw from the agreement in 1934. The series of treaties begun with the Washington Naval Treaty effectively ceased on September 1, 1939, with the beginning of World War II. While in place, the treaty did somewhat limit capital ship construction, however, the per vessel tonnage limitations were frequently flouted with most signatories either using creative accounting in computing displacement or outright lying about a vessels size.

The Future of the Coastguard Essay Example | Topics and Well Written Essays - 3000 words

The Future of the Coastguard - Essay Example Apart from that, its function as a search and rescue service and as an environmental monitoring and protection one, cannot be underestimated or undervalued. The coast guard is essential in the life of any coastal or island country and its importance is expected to increase. While there are hardly any who are not aware of the presence, aims and objectives of all of the army, the navy and the air force, only a handful of people have a similar awareness of the coastguard. Although some countries, such as the United States, Canada and Japan, define the coast guard as a division of the national military, its importance is generally underestimated (LaGuardia-Kotite and Ridge, 2006). Popular understanding of the coast guard is that it acts as a vessel and life rescue service and, in some instances, to monitor fishing across the national coastlines and waters. This understanding barely touches upon the duties, responsibilities, aims and objectives of both civilian and military coast guard services, nor does it even hint at the fact that the coast guard, in the first and last, is primarily responsible for coastal and port security. In other words, the responsibilities and functions of the coast guard directly tie in with national security (LaGuardia-Kotite and Ridge, 2006). This research paper, which shall highlight the multiple functions of the coast guard s... n, shall, hopefully, illustrate that insofar as coastal countries are concerned, the coast guard plays an invaluable and vital role; a role which directly contributes to increased national security. Historical Background The Coast Guard first emerged in the early nineteenth century and in direct response to an ever growing need to protect coastal areas from smugglers, not to mention rescue services for vessels and fleets in distress (LaGuardia-Kotite and Ridge, 2006). While there is, currently, hardly a coastal country which does not have a coast guard service, tracing its history in the United Kingdom is particularly informative, not just because the first coast guard service emerged in that country but because both civilian and military division of the UK coast guard functioned, and to a degree continues to function, as the model for the same in coastal nations across the world (Thoreaux, 2006). Prior to expanding upon the genesis of the coastguard and over viewing its historical evolution in Britain, it is interesting to point out that the United States Coastguard strenuously maintains that the historical roots of this service lie in the United States (Beard, 2004). According to this argument, the outbreak of conflict between the United States and Britain regarding the colonisation of North America, is directly responsible for the evolution of the coastguard. In 1740, with the outbreak of the aforementioned war, military commanders realised the imperatives of stationing men along strategic coastal areas for "look-out" duties (Beard, 2004, p. 78). These men were supposed to keep watch over the impending arrival of enemy vessels and to warn the army (Beard, 2004). Insofar as the function of these men was the protection of coastal areas against the possible

Construction and operation of aircraft fluid systems Coursework

Construction and operation of aircraft fluid systems - Coursework Example The turbine engine and the pneumatic power generation component are integral. Largely, the engine component is responsible to the pneumatic power generation. The constructional design of the power generation component takes into consideration the needs to regulate pressure and temperature. Normally, bled air conditions depend on the engine functioning conditions. Critics contend that bleeding the air from the engine can lead to engine suffocation consequently leading to mechanical breakdown. The pneumatic compressor bleeds air from the engine in various stages, a low-pressure port, intermediate and high-pressure port. The compressor has a check valve, which prevents air from moving to low pressure port during bleeding. By design, the low-pressure port is always open, but the shut valve may close it if the engine is a critical condition. The pneumatic power system in aircraft is a secondary power. By design, bleed air is tapped from one or more points along the engine compressor to pr ovide pneumatic power. To achieve the requirement drive shafts, from the engine’s high pressure shaft, drive an accessory gear box on which are mounted generators and hydraulic pumps as well as engine’s own accessories. ... The pneumatic power system has several functions in an aircraft. These functions are air conditioning and pressurization. In aircrafts for civil transport, bleed air is useful in extracting the secondary source of power. The users of the pneumatic power system are air conditioning system and pressurization systems. By design, the air pressure in the aircraft cabin should be at a pressure equivalent to 8000 feet or less and this requires a constant supply of air. It follows therefore that the pneumatic power systems must supply the required pressure in the aircraft. Moreover, the oxygen used in the aircraft requires replacement at constant intervals. Normally, the contaminant level should be under check to avoid suffocation in the aircraft. To control this process, the aircraft requires a source of air pressure that can aid the sucking of the contaminated air and replacing it with fresh air. The pneumatic power systems provides effective high pressure used in the above requirement. Th e process of air conditioning passes through numerous stages ranging from sucking the contaminated air, filtering as well as supplying the fresh air alongside a maintained temperature. The pneumatic power systems drive the ice protection systems. Dangerous icing conditionings are no longer a threat to the modern aircraft because of the modernization of the aircraft components. However, critics have several reasons behind the need to protect aircraft from icing conditions. Some of the reasons adduced against this factor include possibility of accidents resulting from the accretion of ice on the lifting surface of aircraft. The major cause of engine intake icing is the special flow conditions present and most aircraft have at least some provision for de icing in this region of the frame.

A Streetcar Named Desire, by Tennessee Williams :: English Literature Essays

A Streetcar Named Desire In Tennesse Williams' play, "A Streetcar Named Desire" the readers are introduced to a character named Blanche DuBois. In the plot, Blanche is Stella's younger sister who has come to visit Stella and her husband Stanley in New Orleans. After their first meeting Stanley develops a strong dislike for Blanche and everything associated with her. Among the things Stanley dislikes about Blanche are her "spoiled-girl" manners and her indirect and quizzical way of conversing. Stanley also believes that Blanche has conned him and his wife out of the family mansion. In his opinion, she is a good-for-nothing "leech" that has attached itself to his household, and is just living off him. Blanche's lifelong habit of avoiding unpleasant realities leads to her breakdown as seen in her irrational response to death, her dependency, and her inability to defend herself from Stanley's attacks. Blanche’s situation with her husband is the key to her later behavior. She married rather early at the age of sixteen to whom a boy she believed was a perfect gentleman. He was sensitive, understanding, and civilized much like herself coming from an aristocratic background. She was truly in love with Allen whom she considered perfect in every way. Unfortunately for her he was a homosexual. As she caught him one evening in their house with an older man, she said nothing, permitting her disbelief to build up inside her. Sometime later that evening, while the two of them were dancing, she told him what she had seen and how he disgusted her. Immediately, he ran off the dance floor and shot himself, with the gunshot forever staying in Blanche’s mind. After that day, Blanche believed that she was really at fault for his suicide. She became promiscuous, seeking a substitute men (especially young boys), for her dead husband, thinking that she failed him sexually. Gradually her reputation as a whore built up and everyone in her home town knew about her. Even for military personnel at the near-by army base, Blanche's house became out-of-bounds. Promiscuity though wasn't the only problem she had. Many of the aged family members died and the funeral costs had to be covered by Blanche's modest salary. The deaths were long, disparagi ng and horrible on someone like Blanche. She was forced to mortgage the mansion, and soon the bank repossessed it. At school, where Blanche taught English, she was dismissed because of an incident she had with a seventeen-year-old student that reminded her of her late husband.

Electric Motor driven Water Pump activated by Temperature Sensor Essay

In recent times the farmers have been using irrigation technique through manual control in which the farmer irrigate the land at regular intervals by turning the water pump on/off when required. This process sometimes consumes more water and sometimes the water supply land is delayed due to which the crops dry out. It is an electromechanical system. There is advance mechanical water pump which will use to irrigate the crops in farms. The dc electric motor (permanent magnet dc motor or PMDC) will be used to drive this pump. The motor is controlled by the controller which is connected to the battery and the temperature sensor which give a signal to the controller when the surrounding temperature will increase or decrease. The temperature is set to (35OC) in the controller whenever it will increase or decrease from the set temperature it will automatically turn on/off the motor with the help of controller and battery which is connected with it. After that with the help of motor water pump which is connected to the motor will send water to the farms. It will useful for those crops which need constant water and should soak during the growth which will reduce the dry out problems of crops. Block Diagram of Electric motor driven Water Pump. 101917515367000 PARTS WHICH WE ARE USING FOR THIS PROJECT. Waterproof temperature sensor Battery PMDC electric motor Temperature controller Mechanical water pump PROBLEMS Two of the most widely recognized issues with cultivating water system frameworks need to do with water system booking. Water system booking is just noting the inquiries of â€Å"When do I water?† and â€Å"To what extent do I water?†. Beginning a water system cycle too soon as well as running a water system cycle too long is considered overwatering. At any rate, this training squanders water and cash. Be that as it may, over watering can cause edit harm if done on a delayed premise. In like manner, beginning a water system cycle past the point of no return or not running the framework for a sufficiently long timeframe is considered under watering and can cause decreased yields and poor harvest quality which can influence cost. There is also one most common problem which is faced by most of the farmers is field situated miles away from their homes. They have to travel daily base at several time to start or stop the irrigation water pump which is too important for the crops which consume more time. some time due to over irrigation and under irrigation crops are damaged by which farmer face big loss as shown in picture 1.1. Some farmers have more land and they have more need of manpower because of manual turning on/off for water pump which will take more time and become costly because of labor. . Problems sometimes without automatic irrigation system picture of the farm. AIM/OBJECTIVES A model of controlling irrigation facilities to help millions of people. In many countries, agriculture plays an important role in shaping up the economy and the climate conditions are anisotropic. the main purpose of this project is to save crops from dry out and the time which is also important in human life. The model uses temperature sensor technology with the controller to make smart switching devices. It is the basic automatic switching mechanism of motor water pump using the sensor from surrounding temperature. This system can be operated at night and water which loss from evaporation is thus minimized. The most significant advantage is that water is supplied only when the temperature is increased and the plant has need of water. It works according to temperature and keeps soil soaked whenever it going to dry because of temperature. It will also reduce the consumption of water and save the lot of water which will more beneficial for the dry areas of the world. There is also one more biggest advantage of this project is it will also help to increase the production of the crops and save crops from dry out which is also good for the farmers and those countries which totally depend on the farming. It is the highly sensitive product with the low cost by which poor farmers can also buy this in their budget. With the help of automatic irrigation system picture of a farm.

The Sexualization Of Female Youth - 1754 Words

In addition to allowing their daughters to wear sexually provocative clothing, some parents will pay for their daughter to get plastic surgery, some of which include breast augmentation and nose jobs. The APA states that in 2006 the American Society of Plastic Surgeons reported that they performed close to 80,000 surgeries on teenagers younger than 19 years of age, the previous year (15). One can only assume that the teenagers that get plastic surgery have their parents’ approval because insurance does not cover the costs of cosmetic surgery. However, the research report does not state how many of the plastic surgeries performed in 2005 were elective surgeries. Parents are also contributing to the problem of the sexualization of female youth by competing against other parents. Author Meg McSherry Breslin quotes family therapist and author William Doherty, in her article as saying that parents contribute to girls’ sexualization by using â€Å"competitive parenting. † Parents will compete against each other to prove that they are the better parent, by allowing their daughter to appear and act older than she is. When parents act this way, they are in a sense asking the media and retailers to keep coming out with new more grown up trends so that they can stay ahead of the other parents (qtd. in Breslin 15). Additionally, there are parents that enroll their toddler daughters in beauty pageants that encourage the young girls to act flirty to win votes.
