F-86 Sabre - Korean War Fighter

F-86 Sabre - Korean War Fighter Designed by Edgar Schmued at North American Aviation, the F-86 Sabre was an evolution of the companys FJ Fury design. Conceived for the US Navy, the Fury possessed a straight wing and first flew in 1946. Incorporating a swept wing and other changes, Schmueds XP-86 prototype first took to the skies the following year. The F-86 was designed in answer to the US Air Forces need for a high altitude, day fighter/escort/interceptor. While design began during World War II, the aircraft did enter production until after the conflict. Flight Testing During flight testing, it is believed that the F-86 became the first plane to break the sound barrier while in a dive. This occurred two weeks before Chuck Yeagers historic flight in the X-1. As it was in a dive and the speed was not accurately measured, the record was not officially recognized. The aircraft first officially broke the sound barrier on April 26, 1948. On May 18, 1953, Jackie Cochran became the first woman to break the sound barrier while flying an F-86E. Built in the US by North American, the Sabre was also built under license by Canadair, with a total production run of 5,500. Korean War The F-86 entered service in 1949, with the Strategic Air Commands 22nd Bomb Wing, 1st Fighter Wing, and 1st Fighter Interceptor Wing. In November 1950, the Soviet-built MiG-15 first appeared over the skies of Korea. Vastly superior to every United Nations aircraft then in use in the Korean War, the MiG forced the US Air Force to rush three squadrons of F-86s to Korea. Upon arriving, US pilots achieved a high level of success against the MiG. This was largely due to experience as many of the US pilots were World War II veterans whereas their North Korean and Chinese adversaries were relatively raw. American success was less pronounced when F-86s encountered MiGs flown by Soviet pilots. In comparison, the F-86 could out dive and out turn the MiG, but was inferior in rate of climb, ceiling, and acceleration. Nevertheless, the F-86 soon became the iconic American aircraft of the conflict and all but one US Air Force ace achieved that status flying the Sabre. The most famous engagements involving the F-86 occurred over northwestern North Korea in an area known a MiG Alley. In this area, Sabres and MiGs frequently duelled, making it the birthplace of jet vs. jet aerial combat. After the war, the US Air Force claimed a kill ratio of around 10 to 1 for MiG-Sabre battles. Recent research has challenged this and suggested that the ratio was much lower. In the years after the war, the F-86 was retired from frontline squadrons as the Century Series fighters, such as the F-100, F-102, and F-106, started to arrive. Overseas While the F-86 ceased to be a frontline fighter for the US, it was exported heavily and saw service with over thirty foreign air forces. The first foreign combat use of the aircraft came during the 1958 Taiwan Straight Crisis. Flying combat air patrol over the disputed islands of Quemoy and Matsu, Republic of China Air Force (Taiwan) pilots compiled an impressive record against their MiG-equipped Communist Chinese foes. The F-86 also saw service with the Pakistani Air Force during both the 1965 and 1971 Indo-Pakistani Wars. After thirty-one years of service, the final F-86s were retired by Portugal in 1980.

Orporate law - Essay Example This software is directly connected to ASIC. However if a person doesn't wish to engage in this and instead wishes to contact ASIC directly, they will need to do the following: Once the same is selected, it needs to be reserved with ASIC. This is done by completing 'Form 410' that is meant for this purpose. Once the form is completed, ASIC would reserve the name for a period of two months. Names are not indefinitely reserved and extension can be requested. Reserving a name is important because once you have decided on a name and you do not want anyone to use it and there is still some time before you can register the firm then ASIC protects your name for the period. e) The Banned and Disqualified Registers contains information about persons who have been disallowed by the government to engage in the management of a company. Some of them are banned from participating in the financial services industry completely. The registers would contain information such as person's full name, his address, the date when banning order was passed and the date when it would end. These registers are divided into four categories namely: This register contains information only about persons who have been disqualified from managing a corporation under the Corporations Act. The notices about such persons are sent to the ASIC and their names are then added to the register. However it must be carefully noted that there are other persons who are not allowed to manage a corporate because they are bankrupt or have a criminal record. The notices may not reach ASIC in these cases and thus their names do not appear on the list. Banned Securities Representatives Register This registers contains names of pre-AFS licensees. The people who hold these licenses act as authorized representatives of licensed advisers. In the case the adviser or a representative is prohibited by the ASIC for giving advice, their names will appear in this register. These people are also part of the Banned and Disqualified register but their names may not be duplicated there. Banned Futures Representatives Register: The people on this register are those who have the pre-AFS license but are not allowed to practice as advisors in future. AFS Banned/Disqualified Persons Register Any person who works in the financial services sectors needs to have AFS license or work as a representative of someone who has this license. These people are authorized dealers and their names can be found on the list of authorized advisors. However under FSR legislation, which commenced on 11 March 2002, there are

Data Collection Proposal Essay Example | Topics and Well Written Essays - 250 words

Data Collection Proposal - Essay Example (2006). The difference between primary and secondary sources of data is crucial in social research. Primary sources are data which are unpublished; that is, the researcher has gathered them directly from the target individuals or organization. Primary data include data from fieldwork, interviews, and unpublished documents like minutes of meetings. On the other hand, secondary data are any data which a researcher has gathered that have been published before. Secondary data include previously published books, journal articles, and newspaper articles. Mixed method that includes qualitative and quantitative data will be used in this research. Qualitative data will used determine if Bariatric surgery put patient at long term risk and complications of weight. Quantitative data will be used in determining the number of patients who responded differently when put under Bariatric surgery. Primary data will be collected from healthcare providers with information on new devices, drugs, delivery systems, and software for managing patients who have undergone Bariatric surgery. All the legal and ethical issues were taken into consideration as stipulated by law. 50 patients who had undergone Bariatric surgery will be randomly sampled from the information provided by the healthcare providers. This will provide a sufficiently large but feasible number to use in the analysis. Descriptive statistical analysis will be used to analyze the data. This will help in explaining how the data look, (by giving the minimum and maximum values), the what the centre point of the data is (by giving the mean), and how spread out the data may be related to one of more aspects (by giving the standard

V&Cwk3 - Essay Example ent who comes for career counseling or any other counseling is a way to cause harm to the client which is a violation of A.4 (a), which says that counselors are to do no harm to their clients. Section B explains information about confidentiality and the most important section to me is B.1 (a) which talks about respecting client rights, taking into consideration multicultural and diversity issues. This section brings to mind that it is important to understand how different cultures see confidentiality, privacy views toward disclosure, and more (NCDA, p. 10). Since we live in a global world, it is important to be well rounded as a counselor. Section C speaks to professional responsibility, Capuzzi and Stauffer state that this section says that "professionals must perform at the highest level of their ability" (p. 97). I agree with this statement and section C.2 (a) is most important in this section because it says that career professionals must only work within the "boundaries of their competence" (NCDA, p. 15). This means as an example, that a career professional does not engage in mental health counseling because it is not within the scope of practice. I believe this is important because professionals must understand they cannot be everything to every client. They are governed by their "education, training, supervised experience, state and national professional credentials and appropriate professional experience" (NCDA, p. 15). The standards that I chose to compare with the NCDA standards re the American Counseling Association (ACA) standards. The first difference between these two that I see are the way they are set up for reading. The ACA standards have thee columns and each section is separated by a blue box so the reader knows which section they are in. The NCDA guidelines are easier to read because they are spaced out a little more. Both guidelines speak to the counseling relationship and they both say that counselors should avoid harm to clients. The ACA

Forensic Anthropology Study of Bones

Forensic Anthropology Study of Bones Introduction Anthropology is the study of humankind, culturally and physically, in all times and places. Forensic Anthropology is the application of anthropological knowledge and techniques in a legal context (Hunter, 1996b). This involves detailed knowledge of osteology, anatomy, and to a lesser degree pathology, to aid in the identification and cause of death of skeletal and severely decomposed human remains. The application of forensic anthropology is specifically useful when human remains are extremely difficult for the medico-legal team to identify, and these remains are often a result of decomposition, dismemberment, severe burning and charring, and submersion in water for prolonged periods (Haglund and Sorg, 1996 and 2001). It is a fallacy to believe that forensic anthropology applies solely to skeletal remains. In many instances, particularly in the United Kingdom, a forensic anthropologist is required to analyse remains with partial soft tissue. The geographical magnitude of the United States usually dictates that the American forensic anthropologist will encounter more skeletonised remains than those still possessing soft tissue (Uberlaker and Scammell, 2000), however, the opportunities for cadavers to decompose to a fully skeletonised state are severely reduced in the UK. Similarly, there are specific instances where remains can be uncovered in varying states of entirety, including mass disasters, such as train and aircraft accidents, and instances involving human rights infringements (Cox, 2003). However, in the United Kingdom, forensic anthropology is yet to be nationally accepted or acknowledged as a credible and valuable addition to the forensic science armoury, and until recently, the number of cases involving forensic anthropologists has been limited. Although the trained and accredited forensic anthropologist has the capability to undertake a wide range of analyses, and has the potential to add greatly to the field of forensic science, this essay will briefly outline the predominant methodologies employed by the forensic anthropologist in the identification of human remains. Age and sex estimation The uses of forensic anthropology in cases where human remains are not easily identifiable centre around five basic questions which the discipline is uniquely empowered to answer: Whether the remains are human; the number of individuals represented; the interval of times since death; the identification of the individual; and the cause and manner of death (Menez, 2005). Part of that identification is the determination of the age at death and sex of the individual. The topic is immense, however, superficially the process of age determination involves three foci of analysis: tooth eruption and erosion; epiphyseal closure; and the length of the long bones (Hunter et al., 2001; Byers, 2004). Similarly, determination of sex is possible via the analysis of the pelvis, the cranial and mandible characteristics, and the diameter of the femoral and humeral head. As a general rule of thumb, males usually present a more prominent brow ridge, nuchal crest, glabella and gonal angle. Women have a wi der pelvis, a wider sciatic and less pronounced cranial characteristics. Stature and race evaluation Forensic anthropologists can use formulae to determine height based on the length of long bones. The longest bone, the femur, is most applicable for analysis, however estimations are also possible from the metacarpals in the hand. Anthropologists are able to establish the individualà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s weight by the wear on the bones at certain characteristic points. They can also verify an individualà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s general physique from the ridges created via muscle attachments. From muscle attachment characteristics, it is possible to determine whether the individual was right- or left-handed as there will usually be more muscle attachment evidence exhibited on the bones on the dominant side. An intact corpse can be measured, but a disarticulated or incomplete skeleton has to be pieced together. One generic rule of thumb is that height is about five times the length of the humerus, however there are formulas for height based on other major bones a s well, including the spine, tibia, and femur (Black, 2003). Through the application of forensic anthropology it is possible to identify the racial group to which an individual belongs by examining the anthropometric landmarks of the cranial vault. One of three races can be determined from variations in the facial structure, especially the nose and eye sockets. Facial or head hair, when presented on the human remains, can also help determine race. Evaluation of pathologies It is possible via forensic anthropology to determine if a victim was ever injured or experienced trauma. Predominantly, this involves trauma exhibited on the hard tissue, however, in cases of partial decomposition, soft tissue trauma may also be evaluated and established (Pickering and Bachman, 1996). In the case of a suspected victim, detected bone trauma can be compared with an individualà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s medical X-rays to confirm identity, and the same identification methodology may be applied with regard to dentition and odontological evidence. It is often also possible to determine the cause of death in a victim, particularly in cases of extreme violence. This is determined by analysing indications of trauma, including stab marks, depressions and blunt weapon trauma usually to the skull, fracture patterns, saw marks in cases of dismemberment, and bullets or pellets in or near the body. If the person was strangled, for example, frequently the hyoid bone in the throat is fractured (Nafte, 2000; Rutty, 2001). It is also possible, through toxicology, for the forensic anthropologist to analysis evidence of poison recovered from hard tissue samples. Determination of cause of death can be of particular relevant in cases of human rights abuse. This is an area which appears to be prevalent globally, and forensic anthropologists are currently in operation in Argentina, the Eastern Block, Iraq and the Democratic Republic of the Congo. These analyses are proving highly successful and are assisting in the case-building and prosecution of former dictators and rebel forces alike (Cox, 2003). Post-mortem interval The determination of post-mortem interval (PMI), although relying heavily on the entomological community, the techniques for PMI estimation were developed by prominent forensic anthropologist, William M. Bass (Gilbert and Bass, 1967). Forensic anthropologists are able to approximate the date of death and, the amount of soft tissue that is still present is often the key to determining PMI, although weathering cracks on bones during excessively cold weather or animal and rodent bites may also be used. Generally, females lose one pound of tissue per day during average decomposition; males, in comparison, lose three pounds per day. Acidic soil has a tendency to accelerate decomposition, however, alkaline soil retards it, and the pedology around the body is frequently analysed by both forensic anthropologists and pedologists. Although most frequently the forensic entomologist is required to estimate the post-mortem interval based on insect activity, this is actually an estimate of the period of insect activity, not the specific post-mortem interval. The two are often relatively similar, as the insects arrive and begin their activity shortly following death, however, in some instances there may be factors that serve to delay the onset of insect activity, and these must be considered (Schultz et al., 2005). Determining if the body has been moved following death is essential for this consideration, and the trained anthropologist is competent in this analysis. It is also crucial for the pathologist and anthropologist to assess wounds in terms of pre-, peri- and post-mortem to accurately determine PMI. Conclusion Forensic anthropology is the application of the science of physical anthropology to the legal process. The identification of skeletal, badly decomposed, or otherwise unidentified human remains is important for both legal and humanitarian reasons. Forensic anthropologists apply standard scientific techniques developed in physical anthropology to identify human remains, and to assist in the detection of crime (Hunter, 1996a). While forensic pathologists are trained to analyze soft tissue and organs, their experience with hard tissue is often limited (Hunter and Cox, 2005). In a relatively recent case for forensic anthropologist Charlotte Roberts, a pathologist had been uncertain whether a canine skeleton was actually human or not, illustrating the value of anthropology to the criminal investigation process (Roberts, 1996). The methodology of the forensic anthropologist was eventually adopted during the eventually across Saddleworth Moor during the Moors Murders re-investigation of 1986 -88, and proved partially successful (Hunter, 1996c). The forensic anthropologist specializes in hard tissue morphology, structure and variability, and much of what occurs in forensic anthropology originates from the area of osteology, although some forensic anthropologists may also specialize in body decomposition and entomology. A plethora of further evidence is obtainable and within the capabilities of the forensic anthropologist for analysis, such as entomology, taphonomy, location of clandestine remains (Hunter, 1996c) and so on, however, the methodology of these forensic specialists is exhaustive.

Prefrontal Cortex :: Neurology Brain Medical Essays

Prefrontal Cortex The prefrontal cortex is the most anterior portion of the frontal lobe. It responds mostly to stimuli signaling the need for movement, however it is also responsible for many other specialized functions. It receives information from all sensory systems and can integrate a large amount of information (Kalat 2004). Studies have shown that the prefrontal cortex is responsible for working memory. Working memory is defined as "the information that is currently available in memory for working on a problem" (Anderson 2005). The prefrontal cortex (PFC) also controls behaviors that depend on context (Kalat 2004). For example, if my cell phone rings when I am at the mall or grocery store I would answer it. If it rings while I am at the movies or in class I wouldn't answer it. People with frontal lobe damage often exhibit inappropriate behaviors due to the inability to recognize context. Other studies indicate that the PFC is also responsible for regulating emotions and decision-making. A study was conducted in which participants were presented with three dilemmas. One dilemma was called the Trolley Dilemma: a trolley is headed toward five people standing on the track. You can switch the trolley to another track killing only one person instead of five. Subjects were asked to decide between right and wrong. Brain scans of the participants show that contemplating the dilemmas activates the prefrontal cortex and other areas that respond to emotion (Kalat 2004). Sustaining a lesion to the prefrontal cortex produces a wide variety of side effects. The effects range from minor to severe. You can get a lesion by head trauma or stroke (CJ Long 2005). Possible deficits associated with minor lesions of the prefrontal cortex: - Inability to respond quickly to verbal instructions - Speech dysfluency - Disturbances in understanding complex pictures or words - Difficulties with problem-solving - Deficits in complex tasks requiring inhibition of habitual behavior patterns With more extensive lesions the person experiences greater behavior deficits. These deficits include: perseveration, which is the inability to make behavioral shifts in attention, movement and attitude, decreased creativity, poor recall of verbal and nonverbal material, difficulty writing, and deficits in comprehension of logical-grammatical constructions (CJ Long 2005). Other effects of extensive lesions: - easily distracted - disturbances in memory - defects in time sense - decreased anxiety - less critical of oneself - difficulty with unfamiliar analogies - impulsivity
