Submarine Warfare Essays - Submarines, Submarine Warfare, U-boat

Submarine Warfare Submarine Warfare The First "World War," also known as the Great War, took place after the turn of the century from 1914 to 1918, and was named this because it was the first conflict of global proportions. The war resulted in the loss of military lives and the near destruction of Europe. The massive destruction of the war was largely a result of the use of technology in warfare. The use of technology in warfare was a result of the industrial revolution at the end of the nineteenth century which brought mechanization and mass production to society. This brought the use of things never used or heard of into the war and included airplanes, submarines, and tanks, as well as radio communications, machine guns, and poison gas. The use of submarines played a major part in getting the U.S. to join the war. With the launching of the Dreadnought, the first battle ship to concentrate all artillery power to massive twelve inch guns and break the twenty knot speed barrier, the worlds navies became obsolete overnight. The world powers were rushing to build a new class of war ships to replace the older out dated ones. Germany and England soon became entrapped in a naval arms race, with each trying keep pace with the other's building program. When the War arrived in 1914, both Germany and England had navies made up of heavily armed capital ships, which were large heavily armed and thickly armored battle ships such as Destroyers. The world waited for the clash of Germany's high seas fleet and England's Grand fleet. The Great War ships only had a few encounters such as in the battle at Jutland and Dogger while the underestimated and largely overlooked submarine would play a revolutionary part. In the War's second month Germany's tiny U-boat fleet made up of only twenty six submarines and ranking fifth in size among the war's combatants demonstrated the tremendous offensive potential of the "Underseeboot". On September 5th, 1914 commanding officer on the U-21 Korvettenkapitan Otto Hersing found the British light cruiser Pathfinder moving toward his position, submerging the U-boat had only to wait till the Pathfinder was within his range. He fired a single torpedo and hit the Pathfinder accurately and the ship went down in under four minutes with heavy loss of life. The true eye opener came merely seventeen days later when the U-9, under the command of Kapitanleutnant otto Weddigen, sank three 10,000 ton British armored cruisers, Aboukir, Houge, and Cressy in the course of only one hour using five torpedoes. Approximately one thousand four hundred British sailors lost their lives in the attack and the loss of three capital ships was embarrassing to the British Navy. Naval establishments around the world sat up and took notice at that point. The sinking of the British cruisers had proven the submarine's worth to the military as an offensive weapon but its use against merchant shipping brought the weapon its own place in the military world. On February 4, 1915 angered by the British blockade of the North Sea, Germany declared the water around the British Isles a war zone. Germany now would sink all merchant vessels found in those waters without warning. This was the first time the world had seen a form of unrestricted submarine warfare on merchant shipping. As result England was receiving no goods from the outside world which was very nearly starving out England because of the unmerciful nature of the German attacks. The United States, long a neutral spectator to the war, found herself slowly being drawn into the conflict. Before her entry in 1917 a warning was sent by Germany that American waters would not be immune to the U-boat threat. Germans sent two voyages to the town of Newport, Rhode Island in that same year. After the United states entered the war on April 6, 1917 they waited for a reappearance of the submarines for months before seeing another U-boat. When they finally did it was for the sinking of the American ship S.S. Carolina. The S.S. Carolina was a five thousand ton passenger liner transporting over 217 passengers from San Juan, Puerto Rico, to New York City. When a message was intercepted by a wireless operator that the Isabel B. Wiley was sunk by a German U-boat, no more that fifteen miles away, the message was instantly sent to the S.S. Carolina. Captain Barbour then put his ship in a defensive zig zag pattern to make the ship a less easy target but it was too late. The U-boat had already fired shells in to

Geography Facts About the Amazon River

Geography Facts About the Amazon River The Amazon River in South America is an amazing and important river for the planet and therefore, you need to know about it. Here are the eight most important things you need to know about the Amazon River. 8 Amazon River Facts The Amazon River carries more water than any other river in the world. In fact, the Amazon River is responsible for about one-fifth (twenty percent) of the fresh water that flows into the worlds oceans.The Amazon River is the second longest river in the world and is about 4,000 miles (6400 km) long. (In July 2007 a group of scientists reportedly determined that the Amazon River might just be the longest river in the world, taking that title from the Nile River. It will take further studies to substantiate the claim and for the Amazon River to be recognized as the longest.)The Amazon River has the largest watershed (area of land that flows into the river) and more tributaries (streams that flow into it) than any other river in the world. The Amazon River has more than 200 tributaries.Streams that begin in the Andes Mountains are the starting sources for the Amazon River.Most of the runoff of Brazil flows into the Amazon River along with runoff from four other countries: Peru, Bolivia, Colombia, and Ecuador. Due to the vast amount of water as well as sediment that are deposited where the Amazon River meets the Atlantic Ocean, the color and salinity of the Atlantic Ocean are modified for nearly 200 miles (320 km) from the delta.For much of its path, the Amazon River can be as much as one to six miles wide! During flood seasons, the Amazon River can be much, much wider; some report it is more than 20 miles wide (32 km) in certain places.The Amazon River took different routes since it began to carry water. Some scientists have determined that the Amazon River even flowed west at one time or more, into the Pacific Ocean.

Epistemology versus Ontology in Philosophy Essay

Epistemology versus Ontology in Philosophy - Essay Example Therefore, it may be said that this paper has been written on the assumption that epistemology is better suited than ontology for research design in philosophy. To begin with, one has to understand research design in context of philosophy as a style of writing or expressing ideas. This has a nexus with positivism as well as interpretivism in understanding how knowledge is gathered and used. Johnson et al's text (2000) starts with a study of innate notions. This portion of the book is a study of the elements that lead to speculation and a subsequent formation of perspective. This points to positivism. Throughout this part, the authors have managed to hook the reader on to the idea that speculation is an element that must be used in very discreet doses as more of it can damage the practical side of things in one's mind. (Johnson et al, 2000) As a philosophical notion, this is an ideal that is true to writing. In writing, it is imperative to stick to a certain balance between factual information and a small amount of speculation. This holds on to people's imagination and memories. Therefore, in this part of the book, the authors have merely de scribed a style of writing that has to do with organising ideas and information or interpretivism. This sets the stage for understanding and differentiating between epistemology and ontology. Further into the book, one will find ideals that are connected with principles in the mind. The mind is an organ that churns out thoughts and expressions of the same. These expressions are a part of the basic mental setup of the person concerned. This quality, in turn, springs from an ability to form a successful marriage between imagination and the overall truth surrounding a person. Therefore, these principles work towards defining a certain kind of writing and research design that can be applied by any person for means of appropriate self expression. (Johnson et al, 2000) The second part of the book is about Ideas. Writing is a field where ideation is an important phase before one begins to actually put the ideas down on pen and paper. Where does this ideation happen It happens during one's life experiences. These life experiences revolve around the garnering of values and ideals in life. One's writing often depicts the state of one's belief system. Thus, in describing ideas, Locke has managed to show what a person's preliminary research in writing is based on. This preliminary research comes from what is within oneself. (Locke, 2007) Analysis To begin with, let us define the concepts of epistemology and ontology, individually. Epistemology: This is a field of study that is closely related to philosophy. Epistemology, through the definition of theories and concepts, seeks to study a body of knowledge by applying the relevant definitions. This points towards subjectivism and the use of a positive attitude in deducing and understanding knowledge. In this way, it shares some similarity with ontology. It is a field of stu

Substance Dualism Term Paper Example | Topics and Well Written Essays - 2000 words

Substance Dualism - Term Paper Example Such versions are comprised of substance dualism; psycho-physical parallelism; occasionalism; idealism; double-aspect theory; and epiphenomenalism. I wish to stress on the fact that such examinations will be done to further establish the arguments that will be set on the logicality of duality. Dualism, in its basic sense, emphasizes on the radical difference between mind and matter (Calef). In this reasoning, the mind is not the same as the brain or any other body part. Thus, there exist two independent substances in a person—one material (comprised mainly of bodily parts) and one non-material (human mind) (Philosophy of Mind). The term ‘substance’ is the most essential concept in this statement as it strongly posits the need to treat the mind as an independent object. Formally defined, a substance is a thing or an entity that does not depend on other thing or entity in order to exist (Lacewing). Moreover, a substance may or may not be composed of other substances, may or may not enter into relationships with other substances, but will always have specific attributes (Blutner). Through this definition, the ‘dualist perspective’ argues that there are two fundamentally different objects in a person—the mind and the body—and they do not necessarily need the presence of each one to exist. Thus, while the mind and the body may or may not be in a ‘relationship’ (as to be explored in greater detail in the second part of this paper), they will always possess specific attributes that will make them be as they are (Everitt). Because of this, the human body and the human mind can be discriminated according to attributes of spatial extension (for body) and of thought (for mind). Such attributes are further ‘specified’ by certain states or modes—modes of extension such as form, location texture and weight for the body, while modes of thought such as images, emotions, beliefs,

Couples counseling Essay Example for Free

Couples counseling Essay Woman is a greatest creature of the god. Woman plays an important role in every man’s life. There is a woman behind the every successful man. Men and women are made for each other. Actually they are life partner of each other, but the chance of the death of a partner is more for women than for men.

Generally aged men become widower than young man (U. S. Census Bureau). There are many of similarities and differences between the experiences of the widowers and widows. Comparisons are done by the many people between widows and widowers. But there are some unique experiences in the life of widowers. The course of bereavement is wrought with diversity and variability among widowers. Widowers are not able to adapt the death of their wife easily. Some widowers face greater difficulty in adaptation the death of their wives. But many widowers ultimately become able to withstand or recover quickly from difficult conditions.

Rape and Intimate Partner Abuse In The Lesbian Community Essay

In every 45 seconds, someone is sexually violated in the United States. Out of every 6 women, one has experienced an attempted rape or complete rape. Lesbians and bisexual women remain at increased risk of sexual victimization compared to heterosexual women. In order for a woman to determine the direction of her life, she must first determine her sexuality. Sexuality is a deep, integral part of any human’s life. This should not be a subject of coercion or debate. The society must recognize that a woman has the right to freely pre-determine her sexuality without oppression and discrimination (Burn, 2004). Traditionally, women throughout history and culture have undertaken the role of independent, non-heterosexual, women-connected existence. Lesbianism according to ancient literature review has always existed. The practice has always been unacceptable and deviant. Lesbians are subjected to rape more often than other women. Worldwide, lesbians are subjected to verbal and physical abuse. In most cultures, lesbianism occurs prior to heterosexual marriages. These facts were gathered by Faderman in 1981. Female-female romantic relationships were found in European communities since the 17th century through the early 20th century after studying the fiction and poetry written during this period (Burn, 2004). Today, many societies view bisexuality and homosexuality as a sickness. The societies deny their existence entirely. However, biologists and psychologists believe that both are mere instances of many human variations. After successful lobbying by gay and lesbian political organizations in 1974, the American Psychiatric Association (APA) eliminated homosexuality from its list of mental disorder. The APA now takes the position that homos... ...(2010).

Classification of Epithelial Tissue

Classification of Epithelial Tissue Location of Epithelium The four basic tissue types in the body are the epithelial, connective, muscular, and nervous tissue. These tissues exist and function in close association with one another. The epithelial tissue, or epithelium, consists of sheets of cells that cover the external surfaces of the body, line the internal cavities, form various organs and glands, and line their ducts. Epithelial cells are in contact with each other, either in a single layer or multiple layers. The structure of lining epithelium, however, differs from organ to organ, depending on its location and function.For example, epithelium that covers the outer surfaces of the body and serves as a protective layer differs from the epithelium that lines the internal organs. The overview illustration shows different types of epithelia in selected organs. Classification of Epithelium Epithelium is classified according to the number of cell layers and the morphology or structur e of the surface cells. A basement membrane is a thin, noncellular region that separates the epithelium from the underlying connective tissue. This membrane is easily seen with a light microscope.An epithelium with a single layer of cells is simple, and that with numerous cell layers is stratified. A pseudostratified epithelium consists of a single layer of cells that attach to a basement membrane, but not all cells reach the surface. An epithelium with flat surface cells is called squamous. When the surface cells are round, or as tall as they are wide, the epithelium is cuboidal. When the cells are taller than they are wide, the epithelium is called columnar. Epithelium is nonvascular, that is, it does not have blood vessels.Oxygen, nutrients, and metabolites diffuse from the blood vessels located in the underlying connective tissue to the epithelium. Special Surface Modifications on Epithelial Cells Epithelial cells in different organs exhibit special cell membrane modifications o n their apical orupper surfaces. These modifications are cilia, stereocilia, or microvilli. Cilia are motile structures found on certain cells in the uterine tubes, uterus, and conducting tubes of the respiratory system. Microvilli are small, nonmotile projections that cover ll absorptive cells in the small intestine and proximal convoluted tubules in the kidney. Stereocilia are long, nonmotile, branched microvilli that cover the cells in the epididymis and vas deferens. The function of microvilli and stereocilia is absorption. Types of Epithelia Simple Epithelium Simple squamous epithelium that covers the external surfaces of the digestive organs, lungs, and heart is called mesothelium. Simple squamous epithelium that covers the lumina of the heart chambers, blood vessles, and lymphatic vessels is called endothelium.
