THE BERMUDA TRIANGLE essays

THE BERMUDA TRIANGLE essays The Bermuda Triangle, located between Florida, Puerto Rico, and Bermuda, has had many mysterious events occur over the past five hundred years. There are many facts people can learn from this place. Christopher Columbus was the first known discoverer of the Bermuda Triangle. Many United States planes and ships, as well as the many airlines planes and cruise boats that have been lost, never to be seen again. In the area between Florida, Puerto Rico, and Bermuda, there have been many strange disappearances. Many ships and planes have been disappearing in this area of the Atlantic Ocean. The Bermuda Triangle started being noticed in 1904, when many people became missing. Since 1945, more than one hundred planes and ships have vanished, and more than one thousand lives have been lost in the last twenty-six years (Berlitz 11). The amazing part of this is that many searches have been conducted to find survivors or any wreckage from these boats and planes and nothing has ever been found. Some of the many planes have disappeared during normal flying and while still in contact with their base. The base says the radio just faded out. Many of the disappearances have occurred during or near Christmas. Experts have not yet discovered why the Bermuda Triangle is especially anonymous during this time (Kische 7). After plotting these disappearances on a map, you will find that it has been forming a t riangle or a kite shape. This is why they call it, The Bermuda Triangle. They have made the name, "The Port of Missing Ships," to the place that ships go after they have disappeared. Until this day, many strange disappearances have occurred in this area. Christopher Columbus was the first known observer of this area. It is believed that he discovered this area while on route to what is now known as America. In 1492, Columbus recorded that he and his crew observed a large ball of fire falling from the sky into the sea. He also recorded that his co...

Qu necesitas saber sobre visa paralizada causa 221g

Qu necesitas saber sobre visa paralizada causa 221g Cada aà ±o, aproximadamente la solicitud de un millà ³n de visas americanas, tanto no inmigrante como migrantes, entran en un periodo de anlisis especial conocido como procedimiento administrativo 221g, el cual significa que, por un tiempo,  no son ni aprobadas ni denegadas y la decisià ³n final est pendiente. En este artà ­culo se informa en detalle sobre quà © es realmente el procedimiento administrativo 221g, por quà © sucede, quà © puede hacer el solicitante de la visa y cunto tiempo se demora la obtencià ³n de una respuesta final y definitiva. Puntos clave: Procedimiento administrativo 221g El procedimiento administrativo 221g es una paralizacià ³n temporal de la solicitud de una visa americana. No es una aprobacià ³n ni tampoco una denegacià ³n.Las causas del procedimiento administrativo 221g son variadas: falta de documentacià ³n, necesidad de verificar antecedentes de solicitantes, veracidad de declaraciones en solicitud de visa, etc.Es habitual que la resolucià ³n del procedimiento administrativo 221g se demore 60 dà ­as o menos, pero se conocen casos de demora superior a 8 meses.  ¿Quà © significa el procedimiento administrativo 221g? Cuando el solicitante de una visa americana recibe una notificacià ³n en la que se le informa que su solicitud est pendiente por razà ³n del procedimiento administrativo 221g, debe entender que eso quiere decir que despuà ©s de la entrevista para la visa el oficial consular a cargo  no ha podido tomar una decisià ³n definitiva. En otras palabras, la visa no es aprobada pero tampoco negada definitivamente, sino que pasa a una tramitacià ³n especial que se conoce como procedimiento administrativo 221g.  ¿Por quà © la solicitud de una visa es enviada a un procedimiento administrativo? Las razones pueden ser bsicamente dos: En primer lugar, porque falta documentacià ³n para la visa. En este caso, el oficial consular informar en detalle sobre quà © documentos se precisan y cà ³mo deben ser enviados al consulado una vez que se obtengan. En estos casos es importantà ­simo tener en cuenta que hay un plazo que se especifica para proveer esa informacià ³n. Luego de ese tiempo sin haber entregado la documentacià ³n, la peticià ³n de visa es cancelada y si se desea sacar la visa se tendr que volver a aplicar desde el principio. Y, en segundo lugar, el procedimiento administrativo 221g puede darse por cualquier otra razà ³n. Desde coincidencia en nombre y fecha de nacimiento con otra persona, a informacià ³n variada que pueda tener el consulado y que necesita contrastar antes de tomar una decisià ³n.   Otro ejemplo puede suceder cuando quien solicita la visa ha sido militar en un paà ­s considerado como no amistoso. Tambià ©n en el caso de personas que solicitan la visa y que han visitado o residido en paà ­ses considerados como no amigos de los Estados Unidos. Incluso este problema le puede surgir a empresarios, inversores y cientà ­ficos de algà ºn modo relacionados con tecnologà ­a considerada sensible o de doble uso y que est incluida en la  Technology Alert List. Pero en la mayorà ­a de los casos se trata de asuntos ms comunes, como cuando se sospecha criminalidad por parte del solicitante de la visa o cuando se precisa que una oficina dependiente del gobierno federal de los Estados Unidos realice verificaciones. Por ejemplo, cuando se sospecha que uno de los documentos presentados al aplicar por la visa es falso o lo es alguna de las declaraciones y afirmaciones realizadas en las planillas para su solicitud. Hay que tener siempre presente que las mentiras en este contexto son fraude de ley y puede tener consecuencias muy serias con respecto a las opciones para obtener la visa americana.  ¿Cunto tiempo se demora resolver el procedimiento administrativo 221g? Cada caso es un mundo y no se puede establecer una regla general. Si bien es cierto que en la mayorà ­a de los casos hay una respuesta definitiva antes de que pasen 60 dà ­as, se sabe de casos en los que la demora ha llegado a los ocho meses o ms. Si la demora es mayor a lo habitual, debe consultar con un abogado si procede demandar mediante un writ of mandamus.  ¿En quà © consiste el procedimiento administrativo 221g? En cuanto a en quà © consiste este trmite administrativo 221g, hay dos posibles respuestas. Por un lado puede simplemente consistir en conseguir la documentacià ³n que se necesita y no se ha presentado. En este caso el consulado entrega un papel que dice detalladamente quà © documentacià ³n falta y dà ³nde y cà ³mo se debe entregar. En este caso debe seguir al pie de la letra esas instrucciones. Pero, por otro lado, puede que el trmite consista en una investigacià ³n por parte de una oficina que de algà ºn modo depende de un organismo federal de los Estados Unidos. Por ejemplo, se pueden verificar los antecedentes penales del solicitante o que realmente trabaja donde dice que lo hace. Incluso se puede enviar a un investigador a verificar la realidad de un matrimonio, etc. En este caso la tramitacià ³n va a depender del tipo de problema que se intenta resolver.  ¿Puede pedirse una tramitacià ³n de urgencia de la visa en este caso? No. Es irrelevante que se quiera la visa para empezar un curso, asistir a una boda, cerrar un negocio, etc. o que ya se hubiera pagado el viaje y el boleto de avià ³n. En ningà ºn caso es posible solicitar una tramitacià ³n de urgencia. Por esta razà ³n se recomienda encarecidamente no comprar tickets ni pagar reservas de viajes antes de tener la visa en mano.  ¿Puede verificarse cà ³mo se encuentra el caso? Si se ha solicitado una visa no inmigrante, tipo turista, estudiante, intercambio, trabajo temporal o semejantes se puede acceder a informacià ³n ms bien generalista sobre el estado de la tramitacià ³n de la visa en la pgina oficial del Departamento de Estado habilitada para ello. Si en el papel que se entrega donde se comunica que la solicitud est en trmite administrativo 221g se indica un mà ©todo distinto de verificacià ³n, debe seguir esas indicaciones. Si se quiere recibir informacià ³n ms en detalle, se aconseja contactar al consulado o embajada que tramita la visa. En estos casos es altamente recomendable dejar transcurrir al menos dos meses desde la fecha de la entrevista al momento de contactar por primera vez por esta razà ³n. Si se trata del supuesto en el que pidieron documentacià ³n adicional, debe contar los sesenta dà ­as a partir de la fecha del envà ­o de dicha documentacià ³n.  ¿Quà © sucede cuando se llega a una solucià ³n definitiva? La visa puede ser aprobada o negada. En este à ºltimo caso, se notificar la causa. En ambos supuestos  se enviar el pasaporte a su titular por el procedimiento que sea habitual en el consulado donde se solicità ³ la visa. El consulado puede negar la aprobacià ³n de una visa por razones que caen en dos grandes categorà ­as: Por causa de ineligibilidad, que es la ms comà ºn y aplica solamente a las visas no inmigrantes, como la de turista, estudiante, inversià ³n, intercambio, etc., o por alguna de  las  causas de inadmisibilidad  que impiden el ingreso a Estados Unidos, y que aplican tanto a las visas no inmigrante como de las de migrante. Cuanto  sucede una causa de inadmisibilidad, a veces es posible pedir un perdà ³n, tambià ©n conocido como waiver o permiso. Sin embargo, en estos casos es recomendable consultar con un abogado porque son casos difà ­ciles y no siempre es posible. Consejos en forma de tests Se aconseja tomar este quiz o  test de respuestas mà ºltiples en el caso de solicitar una visa no inmigrante. Conocer las respuestas le ayudar a entender cà ³mo sacar una visa, conservarla, renovarla y evitar que la cancelen.   En el caso de que el interà ©s sea obtener una visa inmigrante, es de interà ©s tomar este test sobre conocimientos bsicos de la green card, tambià ©n conocida como tarjeta de residencia permanente o green card.

How does the understanding of the origins and spread of nationalism Essay

How does the understanding of the origins and spread of nationalism inform our reading of Frankenstein - Essay Example Frankenstein saw the light of the day when the modern western World was beginning to evolve. The people desperately needed a change and were fed up of the royal harassments. Most of the monarchies did not care for the welfare of the people and had no concrete plans to improve the living conditions of the people. The French Revolution evolved within the minds of the people, waiting for an opportune time to strike. This book was written during the Romantic movement of the early 19th century. The issues raised then are relevant even today. Mary Shelly is more or less prophetic in her observations as for the causes that led to the evolving of the spirit of Nationalism. If one turns the pages of blood-soaked history of humanity, the conclusion is obvious. An individual’s aspirations should be fulfilled peacefully by the rulers and those occupying the seats of power. If that does not happen, what would be the results when those aspirations are attained by violent processes by adopti ng most irresponsible procedures! The concepts of individual freedom and respect for one’s dignity—these are time-tested concepts for the healthy growth of the society. Any political philosophy that tries to suppress these ideals by force will not last for long. We have seen the rise and abrupt fall of Nationalism evolved by adopting Communist ideology in Russia and some other western countries. The procedures and developmental strategies being officially encouraged by the Communist regime of China would put the Capitalist countries in the backseat. When Mary Shelley (then Mary Godwin) wrote Frankenstein in 1816, political conditions were such that the human spirit was tested to the brink. The prominent authors of the time took to serious writing on the concepts of uniqueness and self-realization. The individual’s emotions amidst their daily struggles became good story topics. These topics had the back up of direct experiences and hence they

The neurotransmittion pathology and thier malfuction due to cancer Research Paper

The neurotransmittion pathology and thier malfuction due to cancer - Research Paper Example Such disease as cancer can be the reason of various transmitter pathologies. The study of the Leipzig University showed that at least one of the three cancer patients in German hospitals also has neurotransmitter pathology. Cancer patients with the psyche abnormal are more likely to complain of pain and tend to suicide. ). Cancer also leads to decreased concentration ability, disruption of thinking, change in level of consciousness, disorientation, violation of perception, disorders of the sleep cycle, memory impairment, etc. Even schizophrenia can be provoked by cancer. Besides, these two diseases share common genetic roots. Thus, it is necessary to treat both physical and mental disorders simultaneously. Key words: cancer, mental disorder, neurotransmission pathologies, neurotransmitter, schizophrenia. For a long time the mental and physical health were treated separately from each other, that, according to the World Federation for Mental Health, was not beneficial to patients. Tha t is why the main theme of World Mental Health Day-2010 was the relationships between mental and physical conditions and their importance for providing the most effective patient care. According to the World Health Organization, more than 450 million people worldwide suffer from mental disorders. Approximately 121 million patients' mental disorders are accompanied by serious illnesses such as cardiovascular disease, cancer, diabetes, etc. Sergei Tyulyandin, a head of clinical pharmacology and chemotherapy, the deputy director of Clinical Oncology Research Center in Moscow, reported that many cancer patients, as a result of special treatment, recover, they need not only social support, but professional help of psychologists and psychiatrists for their early return to normal work and social activities (WHO, 2010). Approximately half of cancer patients have the developing mental disorders. In descending order, these disorders are as follows: violation of adaptability, affective disorde rs, organic mental disorders, personality changes, fears. Each of these disorders can be treated under the influence of psychotherapy and / or psychopharmacological methods. â€Å"Neurotransmitters, as well as hormones, are primary messengers, but their release and the mechanism of action in chemical synapses are very different from those of hormones. In the presynaptic cell, vesicles, containing neurotransmitter, release it locally into the very small synaptic gap† (WHO, 2010). Drawback of any of the neurotransmitters can cause a variety of disorders, such as various types of depression. And such disease as cancer, especially its severe forms, can be the reason of transmitter pathologies (Tilan, & Kitlinska, 2010). The study of the Leipzig University, during which 689 patients with various tumors were surveyed, showed that at least one of the three cancer patients in German hospitals also has neurotransmission pathology. As it turned out, 32% of patients suffered from mental illness, 11.6% had several mental disorders. Most often it was depression. The patients perceived the diagnosis and chemotherapy seriously (Universitat Leipzig, 2007). Patients with the psyche abnormal are more likely to complain of pain. However, psychological factors are too often used to explain the pain that has no medical issues. Cancer patients have a moderately increased risk of suicide (mostly within 1 year after diagnosis). Risk factors include

Buddhist art at Asian art Museum in SF Essay Example | Topics and Well Written Essays - 1250 words

Buddhist art at Asian art Museum in SF - Essay Example The architectural designs of the walls and lights bring anyone inside into a time of serenity and ancient civilization which Buddhism stand for. The pillars are arranged parallel to the series of time warps inside the whole journey in the museum. Each segment inside the museum depicts a historical time that attributed to the living conditions of each country under the Buddhism religion. For example one of the artifacts that peeked my interest during visit in the Asian Museum was the artifact entitled "Bodhisattva crossing over". This artifact is made from nephrite (also known as jade) which size comprise of: Height 9 in x Width 6 1/2 in x Diameter 3 in, Height 22.9 cm x Width 16.5 cm x Diameter 7.6 cm. This jade carving was made from the time of Chin Dynasty in China. For our information, Qin Dynasty is one of the most influential and greatest dynasty in China headed by Emperor Qin Hwang Ti. During this time, arts have been one of the most precious means of depicting arts to preserve and foretell the significance of this dynasty during that time. Nephrite or much known as Jade is a precious stone (a green colored stone, which is uniquely made). Jade is considered to be one of the most precious stones every used in China, especially during the ancient times. To be able to create a form in jade one needs to patiently polish in order to create depth and form. This symbolical artifact used a significant precious stone to share to the world and to people that during the Qin Dynasty, Buddhism is the most significant religion ever followed by most people in China. The image in this artifact is intricately done because each curve, shapes and depth formed the message of the piece. The top portion of the artifact is shaped form like a cave, which the depth of the piece has generally created a distinct image of a person inside a cave. The bottom of the artifact is series of layered curved like waves forming which symbolically moving towards the right side (facing the artifact). In addition to the bottom portion of the artifact, the curves as mixed with various sizes (big and small currents); that also is mixed with stoned form enveloping the waves in each side. The middle part of the artifact is slimmed down in size, which adds another form and balance into the whole piece. The middle portion contains an image of a person, who is believed to be Buddha (or known as the enlightened one). The image of Buddha in the artifact is standing on top of the big and strong currents and as he is also enveloped above by the cave forming stones. The balance in t his artifact is blended with a piece of branches with tiny leaves growing in each of its edges. Buddha's gown was curved finitely creating a gentle movement of alternating flowing of the cloth as it follows the blowing wind. Chinese arts developed every dynasty. Each century or decade, the art and literature of China embodies the depth, symphony and music that each creator and artist have appreciated and grateful for. Buddhism in this creation is highly looked up and followed by everyone. Sakaymuni Buddha or Sidharhta (as he was commonly known for) has a lot of divine teachings to which

The Use of X-Rays in Dentistry Essay Example for Free

The Use of X-Rays in Dentistry Essay Dentistry is increasingly becoming a major part of people lives in today’s society, being taken for granted and often little thought about. As technologies advance treatment becomes cheaper, quicker, and the outcome becomes more aesthetically pleasing and longer lasting. As braces, dentures, crowns, procedures and techniques change and improve at an alarming rate, one aspect has remained the same for a longer period of time. This is the use of X-Rays. X-Rays have been used in dentistry since the mid 1900’s, and continue to be used in the same way today. They are an effective way of finding and identifying various oral problems, allowing for early prognosis and prevention of more serious issues. How is an x-ray produced? Diagram showing a Dental x-ray tube. In a dental (and most other uses of x-rays including all medical uses) x-ray tube, x-rays are formed as electrons from a hot wire filament are accelerated onto a target anode. A high-voltage unit is used to set the anode at a large positive potential compared to the negatively charged filament. The electrons are pulled onto the anode at very high speeds and are suddenly decelerated on impact. As this impact occurs, some of the kinetic energy is converted into electromagnetic energy, as x-rays. This means that the anode therefore emits x-rays as a result of being smashed with high-energy electrons. The x-rays spread out from the focal spot, through the tube window and onto the region to be examined. How is an image formed? X-ray films that are used in dental radiography consist on an emulsion/gelatine mix containing chemicals that are sensitive to x-ray radiation. This is a silver halide either bromide or chloride. The emulsion/gelatine mix and their suspension is set onto a flexible, transparent tinted blue base. Emulsion is used in all types of analogue photography, but the type used in x-ray photography is of a different kind to that used in light photography. The emulsion is usually coated on both sides of the base in layers around 0. 1mm thick. As both sides of the base are coated, there is twice the amount of radiation sensitive silver halide, and so the speed at which an image is produced is increased significantly. Another way to increase the speed of producing an image would be to just have one side with a larger thickness of emulsion. This however would slow down the developing, fixing and drying stage, meaning taking x-rays would take an unreasonable amount of time. Some x-rays requiring more detail use film with emulsion on one side only. When x-rays, gamma rays, or light strike the grains of the sensitive silver halide in the emulsion, some of the halide (Br- or Cl-)  ions are released and captured by the silver (Ag+)ions. This chemical change is of such a small nature that it cannot be detected by ordinary physical methods and is called a latent (meaning hidden) image. However, the exposed grains are now more sensitive to the reduction process which happens during development of the film. When exposed to a chemical solution (the ‘developer’), and the reaction results in the formation of black, metallic silver. It is this silver, suspended in the emulsion-gelatine on both sides of the base that creates an image. Seeing things with X-Rays Different materials have different properties, including x-ray absorption ability. This is exactly the same with body parts, especially teeth. Radiation passes through skin the easiest, followed by the guns and soft tissue. These parts show up as the very darkest areas on an x-ray. Harder tissues absorb and black more radiation from hitting the film and so show up as much lighter areas. Metal implants, fillings and crowns (most artificial features) show up as the brightest white. The different depths of materials is also shown, nerve endings and dentine contours being visible on most developed films. This image shows that a root canal procedure has been successfully completed, meaning less time and money is wasted fixing procedures that have failed. Also visible is an amalgam filling (Brightest white) Measuring Radiation The Sievert The  sievert  (Sv) is the  International System of Units  (SI)  derived unit  of  equivalent radiation dose,  effective dose, and  committed dose. Quantities that are measured in sieverts are designed to represent the  stochastic  biological effects of  ionizing radiation. The sievert should not be used to express the unmodified  absorbed dose  of radiation energy, which is a clear physical quantity measured in  Grays. To enable consideration of biological effects, further calculations must be performed to convert absorbed dose into effective dose, the details of which depend on the biological context. This can be far more complicated than just multiplying by a weighting factor. The sievert is a fundamental part in  radiation dosimetry, and is named after  Rolf Maximilian Sievert, a  Swedish  medical physicist renowned for work on radiation dosage measurement and research into the biological effects of radiation. One sievert equals 100  rem, an older unit of measurement still used in many areas and by older generations of practitioners. One sievert carries with it a 5. 5% chance of eventually developing cancer. Doses greater than one sievert received over a short time period are likely to cause  radiation poisoning, possibly leading to death within weeks. This is a major risk considered in dental use as many doses of radiation could be received during a day in surgery.

CANTERBURY TALES THE MERCHANT’S TALE Chaucer has let January become the character he is partially down to the fact of his age. We know January is highly sexually driven without a doubt. Yet Chaucer leads us to believe that this is down to his personality and character rather than his age being used as a justifiable tool; so what if the man is 60 he still wants to have sex right? We are told that January has a sexual appetite and regularly feeds with mostly a selection of middle aged women, so when he acquires himself a young and "untouched" girl as a wife we are taken aback. At this point Chaucer casts age into the conundrum and we begin to see just how January thinks and more precisely what he desires. Justinus and placebo's scene with January for me is more like him talking to himself and there being an angel on one shoulder and a devil on the other. (This scene is very resemblant of Dr Faustus in which the Good Angel and Evil Angel appear to Faustus.) Placebo is the "devil" and the free thinking conscienceless side of January whilst Justinus is the angel who shows morals and ethics. This is almost an externalization of his mind frame, revealing both halves of his thought. Chaucer has used this scene well to show us exactly the knight's thoughts. As the characters tell him what they think, inversely it is really what he thinks. (He chooses to ignore Justinus and by listening to Placebo he listens to what he wants and desires.) The recklessness for January is his great lack of realism. Not only is it portrayed by the way he expects to have a young wife at the age of 60, but by the way he thinks that he "still has it" and that his age has not affected his status with women. This is one of the seven sins that Chaucer uses in all of the Canterbury tales; vanity. This is reinforced by the way he refuses to listen to Justinus. Although he is a bachelor right unto the point where he meets May and marries her, we have been given little or no real background to his life, his age and his masochistic ways. The total expectation of a "young and fair" wife is surely meant to be interpreted as arrogance. Yet the way January voices his expectation, one casts asides their views of his arrogance and surprisingly adopt one of empathy towards him.
