Usually a pre-preparation technique, as to loosen peels of vegetables, fruits, and nuts, to partially cook French fries or other foods before service, to prepare for freezing, or to remove undesirable flavors. BOIL To cook in water or other liquid that is bubbling rapidly, about 21. 2 degrees F (100 degrees C) at sea level and at normal pressure BRAISE (1)To cook covered in a small amount of liquid, usually after preliminary browning. (2) To cook certain vegetables slowly in a small amount of liquid without preliminary browning. BROIL To cook with radiant heat from above DEEP-FRY To cook submerged in hot fat. DEGLAZE To swirl a liquid in a saute pan, roast pan, or other pan to dissolve cooked particles of food remaining on the bottom. DRY-HEAT COOKING METHODS Methods in which heat is conducted to foods without the use of moisture. FRY To cook in hot fat GLAZE To give shine to the surface of a food by applying a sauce, aspic, sugar, or icing, and/or by browning or melting under a broiler or salamander or in an oven. GRIDDLE To cook on a flat, solid cooking surface called a griddle. GRILL To cook on an open grid over a heat source. MOIST-HEAT COOKING METHODS Methods in which heat is conducted to foods by water or other liquid (except fat) or by steam. PAN-BROIL To cook uncovered in a skillet or saute pan without fat. PAN-FRY To cook in a moderate amount of fat in an uncovered pan. (EN) PAPILLOTE Wrapped in paper (or sometimes foil) for cooking so the enclosed food is steamed in its own moisture. PARBOIL To cook partially in a boiling or simmering liquid. PARCOOK To cook partially by any method. POACH To cook gently in water or other liquid that is hot but not actually bubbling, 160 degrees to 180 degrees F (71 degrees to 82 degrees C). REDUCE. To cook by simmering or boiling until the quantity of liquid is decreased, often to concentrate flavors. ROAST To cook foods by surrounding them with hot, dry air in an oven or on a spit in front of an open fire. SAUTE To cook quickly in a small amount of fat, usually while mixing or tossing the foods by occasionally flipping the pan. SEAR To brown the surface of a food quickly at a high temperature.

The Political Philosophy Of Deception Philosophy Essay

The Political Philosophy Of Deception Philosophy Essay Deception is a part of our everyday lives, it is a part of who we are. What differentiates each and every one of us is the degree of deception that we incorporate in to our lives. Hence, how we look at and interpret deception, and thus, the truth, depends on our perspective, our moral grounding, our exposure and experiences in the wider world- beyond our immediate circle of life. This essay will attempt to find a general definition for deception that will agree with most, and will explore how deception is present in our lives and how that affects the amount of deception involved in politics. It will argue that deception is necessary in politics, and sometimes beneficial (and sometimes not), and this is because we as the general public allows it so. Drawing from the Machiavelli and Strauss schools of thought on how deception is an integral part of politics- and examining this claim through the case studies of the Vietnam and Iraq wars- this essay will conclude that the reason politici ans use deception is because it is sometimes more desirable than the absolute truth and also because it is easier to exploit and appeal towards the human conditions deep inclination towards self-deceit. Lies and deception often used interchangeably however, there is a difference. Citing Mahon (2008), Arico Fallis (2013) states that in order to lie one must say something that they believe is false. Deception engages people in a more deeper extent with the intention overriding the face-worth of a lie; Lies are a form of fabrication, where false information is created and presented as true whereas deception, especially in politics, is more motivated to manipulate, where information which is technically true is being presented out of context in order to create a false implication (Caddell, 2004). According to Caddell (2004) deception depends on two criteria: first, it is intentional; and, second, it is designed to gain an advantage for the practitioner. To understand why and how deception is involved in politics warrants a deeper analysis into the people involved and thus a look into understanding human behaviour and reasoning associated with deception. In the most basic sense, politicians and those who are engaged in the governing processes of our everyday life are only distinguishable from the general public because of the authority we as the general public grant them. Therefore they are also susceptible to the behavioural and cognitive aspects of an ordinary human being. With studies that propose and adopt the notion of self-deceit thus also applies to politicians, so as this essay will argue, will inherently translate into their decisions and actions and thus it is no surprise that politics, as with all other parts of life, would involve deception; therefore, deception is s present and necessary in politics. Self-deception also has many definitions offered its way, and as with the definitions for lies and deception, it will identify with everyone in varying levels- because individuals tend to treat their personal values as a kind of ideal point (Cowen, 2005). He defines it as individual behaviour that disregards, throws out, or reinterprets freely available information; people keep, absorb, and magnify the information that puts their values and affiliations in a favourable light and disregard the rest. Beahrs (1996) adds that deception of others is often accompanied by deception of self and vice versa. This leads to what Williams (1996) calls collective self-deception where the status of politics as represented in the media is ambiguous between entertainment and the transmission of discoverable truth. There are many ways deception is used in politics, and for many reasons. In politics, deception as the term will be used in this essay, could be used as a diversionary tactic, as a means to retain a favourable public relations image, a strategy to handle a difficult and sensitive situation or as the version that is linked to Platonic Noble Lies, used to protect society, a little sacrifice, in order to achieve the greater good (Jacobsen, 2008). Deception in politics and especially foreign affairs, usually involve decisions that are made in the spirit that they are acceptable or excusable because it is done in service of the national interest (Jacobsen, 2008). Therefore according to Beahrs (1996) deceit is probably required for a politician to achieve political success, because we as the people are so engulfed with expectation that it is inevitable and that if it is done in good faith there can be no harsh consequences, so it is easier to handle and deal with. There are many arguments on whether or not deception in politics, in government- essentially as an institution that holds the peoples trust (Williams, 1996) is acceptable. The idealists make a moral and ethical case, where deception, according to an absolute set of standards, is absolutely improper and inappropriate, but according to realists, and dependent on a cost-benefit analysis, the use of deception depends on how good it will achieve and whether it is consistent with protecting national interests and values (Caddell, 2004). Politicians need the people support; and in a liberal democracy one cannot coerce it or expect it as a gift, so they need to put on a persona that is of acceptable standards to others and this leads to deception that builds on (Sofier, 1999). Machiavelli and Strauss: A Look at Modern Day Politics Politicians have less incentive to be absolutely truthful and tend to deceive because they are in office only for a number of years and hence their accountability is limited (Davis Ferrantino, 1996). And politicians know this; according to ex-Australian Senator Graham Richardson, whether one tells the truth is not what really matters, but whether one gets the job done- and in that respect, one simply has to do whatever it takes, and if that involves an element of deceit or misdirection, then so be it (Malpas, 2008). Politicians tend to distract people from the negativity that is involved in everyday political decision making and focus on tunnelling public emotion toward achieving their goals by appealing to their sense of nationalism and personal preferences/group and party loyalty, especially in the event of wars. Deception is politics is almost considered traditional- it is not a recent phenomenon nor is it a fad that peaks every now and then. How politicians conduct themselves have been largely influenced by how politics had been handled in the past and the role deception plays has evolved; it has been more of a learning process, where by using the past political deceptions, politicians have extracted knowledge from what works to what doesnt, and when and how to use it best. Therefore deception in modern politics have become more sophisticated and subtle in its execution. This essay will discuss the schools of thought of two famous political thinkers whose influence has shaped the way deception in politics is carried out. Niccolo Machiavelli, whose most famous work, The Prince, is a handbook that offers effective techniques to retain power- that is still considered relevant today, because it addresses to the primitive, most basic psychological aspect of people. He employs a realist approach to politics, which is still used by many countries in their approach to domestic and international affairs, and adopts the view that politicians need to act dirty and learn how not to be good (Bellamy, 2010). He insists though, that this shouldnt be always the case; there is a right time to apply this to decision making. This is because we live in a world of wolves and traps so one as a politician must be willing to act as lions and employ force to overcome the one and be as cunning as foxes to avoid the second. However, to compensate for their deceitful means poli ticians should use proportionality in their actions, and must appear good; therefore the Machiavellian politician must appear compassionate, generous, reliable, morally upright and honest, yet be prepared to be treacherous, break their promises and use their resources selectively (Bellamy, 2010). But for this to work, nobody must know or want to know- and this is where its success hinges upon; thus the reason deception in politics almost always works because we as the public allows it so, because we ourselves are prone to self-deceit. And especially when it comes to the politicians, as Machiavelli instructed his Prince, force- as it would be used in conflict and wars- might be necessary if the safety and perseveration of community is threatened but one should never to attempt to win by force what can be won by deception; however, he did not instruct carrying out deception because the public cannot handle the truth, it was more out of necessity to ensure national interest are served and power remains intact (Drury, 1996). Leo Strauss on the other hand, did believe that deception was necessary because the public cannot tolerate the truth. He believed that societies should be hierarchical, divided between the elites who rule and the masses who follow, and this was the natural order (Lob, 2007). He states that people need to be told only what is considered the bare minimum and no more and if information is not controlled as such, they would into nihilism or anarchism (Lob, 2007). Religion was seen as the moral grounding that one should lead their lives on, but this only applied to the masses; according to Lob (2007) rulers need not be bound by religion and the ethical codes associated with it because they are required to deceive in order to govern. Strauss believed that humans are wicked and aggressive by nature, and that there needs to be strict governance and this requires unity. But in order to unite the masses the politicians need to find a cause and this could be achieved by referring to an external threat, which could result in wars (Lob, 2007). Following the ideas of these two thinkers, this essay will now look into two wars that have resulted from roots of deception and analyse how political deception works in real life. Fabrication and manipulation have both proved to be useful in the history of warfare and used as a means to vilify opposition, justify violence and to protect national security and other interests. Caddell (2004) states that depending on the intent, militaries at the command of politicians engage in three levels of deception; The U.S. military community traditionally recognizes three levels of deceptionà ¢Ã¢â€š ¬Ã¢â‚¬ ¢based on the nature of the intent; Strategic Deception intends to disguise basic objectives, intentions, strategies, and capabilities whereas Operational Deception, tries to misguide an adversary regarding a specific operation or action you are preparing to conduct and as seen in the American doctrines, finally, there is Tactical Deception which is intended to mislead others while they are actively involved in competition with you, your interests, or your forces. Caddell (2004) also points out that unless under oath in a court or otherwise bound legally to tell the truth, under domestic law there is no constitutional principle that says that the President of the United States or the Executive Branch must tell the truth. Iraq and Vietnam This essay will now discuss two of the most controversial wars (conducted by the United States of America) that have been marred by the use of identified deception in its operation. The Vietnam War (1964-1975) was initiated based on a lie. The incidents that supposedly initiated the war revolved around a couple of incidents in the Gulf of Tonkin; the USA announced two unprovoked attacks on U.S. destroyers by North Vietnamese boats- one of which did not take place and the other being provoked by the USA due to their proximity (ten miles) of the destroyer to the Vietnamese coast and by a series of CIA-organized raids on the coast (Zinn, 1991). The lies followed and multiplied; there were lies that were told by the then-President Johnson who assured the USA was only engaged in conflict with military targets when thousands of non-combatants were killed, and when President Nixon suppressed information from the public about the 1969-1970 bombings of Cambodia, which was considered unnecessa ry (Zinn, 1991). According to Jacobsen (2008), the deceptions that took place were done with full knowledge of the people involved; as admitted by a US General, the objective at the time was to keep the American public in the dark and as later found out President Nixon wrote to Henry Kissinger that it would be very helpful if a propaganda offensive could be [mounted], consistently reporting what we have done in offering peace in Vietnam in preparation for what we may have to do. Following Machiavelli and Strauss, all this was masked by implanting ideas that those who opposed the war were un-American (Beahrs, 1996) and that this was a war being fought to secure American national interests and as a means to fulfil its world responsibility, in order to gather and maintain support and power. The recent Iraq war (2003-2011) is also under much scrutiny for its reasons for initiation and implementation. The main reasons to go to war were based on the suspicion that the Iraqi government harboured chemical weapons and that its dictator leader, Saddam Hussein, could potentially use them; what the justification for how inhumane this would be left out of the picture was that when weapons of mass destruction (WMDs) were actually used in the 1980s, the US government was supportive of the Saddam regime (Martin, 2003). There was more vocal debate against this war at the time, because its direct correlation with the war on terror did not provide sufficient ground for an invasion of that scale. The crucial political asset of trust which broke the publics opinion and respect for government was still not fully restored since Vietnam-because only one third of the Americans supported George W. Bush decision to go to Iraq (Jacobsen, 2008). Despite the undermining reports of the existence o f WMDs and other contradictory evidence, the need to go to war to protect American interests and defeat terrorism was too strong, and to justify this an agency called the Office of Special Plans was created, distinct from the known and reputable defence services, specifically to find evidence of WMDs and/or links with Al Qaeda, piece it together, and clinch the case for the invasion of Iraq (Lob, 2007). The public outrage over these two wars and the other scandals that have resulted after uncovered deception goes on to show that we still regard truthfulness is still somewhat important (Malpas, 2008). Governments have been overthrown and its officials brought to justice because such deception does much damage to our conviction of credibility and legitimacy of our trust; yet, at the same time, as Malpas (2008) suggests, associated with self-deceit, our commitment to truth in itself is a lie. Although truthfulness is an honourable ideal, the realities of life require a more pragmatic approach, and thus we must accept the necessity of the lie, the half-truth, the obfuscation, and the omission (Malpas, 2008). But what is Truth? In order to fully appreciate deception, we must know what truth is. Malpas (2008) defines truth as a combination of both accuracy, understood in statements and sincerity, understood in actions. According to Arico Fallis (2013) you warrant the truth if you implicitly promise, or offer a guarantee, that what you assert is true. Truth is important, because if there is nothing to distinguish beliefs and our errors, deception and our limits. Truth is the idea of ethics that reach beyond the particularities of our personal and social situatedness that makes possible the engagement with others who may not share in that situatedness (Malpas, 2008). Self-deception thus falls under as a failure of sincerity (Williams, 1996). In government and politics, truth is desirable and it holds itself in virtue, but in line with Machiavelli thought, the responsibilities of government are sufficiently different from those of private individuals to make governmental virtue a rather different matter from t hat of individuals; that is for any government that is charged with the security of its citizens, a responsibility which cannot be discharged without secrecy, deception is a necessity- a government would be considered lucky if it can discharge its duties as such without force and fraud (Williams, 1996). Towards Effective Governance In conclusion, this essay will look at whether we can void deception in politics or whether we should not be fazed by its presence. In essence, only a few actually would prefer absolute truth from their political leaders, given that the deception we would expect would be for our own good. We are often victims of self-deception ourselves, and we accept that deception sometimes is acceptable- we engage in it in every day and every way of our lives. But what should not be confused with this admission is that deception in politics should not reflect politicians individual beliefs and opinions; as long as the deception serves domestic and foreign interests in a manner that would not jeopardize public trust and respect- and if it is done in secrecy than outright lying, it could be held with tolerance. But it should be noted that even benevolent deceptions can acquire their own momentum in unpredictable and undesirable directions (Beahrs, 1996). The way we understand politics could have an impact on how we approach and respond to political deception. The Machiavellians of our time, the advisors, the Generals, the state and defence officers insist that they serve national interests, national security and national defense; these phrases put everyone in the country under one enormous blanket, camouflaging the differences between the interest of those who run the government and the interest of the average citizen which would challenge any reservation we might have raising questions about our identity, our role in the society and our priorities (Zinn, 1991). This, depending on our various levels of understanding, would also stand to the extent deception is possible by a government and how susceptible we will be as the masses. To broaden our capacity to detect deception, we should expand our knowledge base; the more one knows, the harder it will be for someone to manipulate information out of context and the more likely one will be able to detect a fabrication (Caddell, 2004). But we must be careful because typically all deceit carries with it an element of self-deception and almost all deception involves to a greater or lesser degree a willingness on the part of the deceiver to be themselves a party to the deceit-to allow themselves to be deceived (Malpas, 2008). However, deception can only be recognized when we retain a sense of truth, so it is crucial that we keep our commitment to our sense of truth, because otherwise according to Malpas (2008), we lose our engagement with ourselves, others, and the world, and we lose, not only our sense of ethics, but we lose a sense of ourselves, of others, of the world. We need to appreciate that even after accepting the general basis for deception and truth in politics, when it really matters our opinions and acceptance vary; that is to say that ones sense of what deception and truth is and how much we will tolerate it comes from, as used in the premise to this essay, how we understand ourselves, our society and our world. In the political arena, the tragedy is that we cannot have perfect freedom or virtue at the same time (Drury, 1996). But what we can strive towards would be a world where deception would not be a means to justify the end and where truth will remain an honourable ideal and politics is not synonymous with deception but with the genuine intention for effective governance. general definition for deception explore how deception is present in our lives and how that affects the amount of deception involved in politics. deception is necessary in politics, and sometimes beneficial (and sometimes not), and this is because we as the general public allows it so. Drawing from the Machiavelli and Strauss schools of thought on how deception is an integral part of politics- and examining this claim through the case studies of the Vietnam and Iraq wars- the reason politicians use deception is because it is sometimes more desirable than the absolute truth and thus it is easier to exploit and appeal towards the human conditions deep inclination towards self-deceit.

The Nature Of Subsonic Airflow

The Nature Of Subsonic Airflow The nature of subsonic airflow over aerodynamic sections and over the aircraft at large must be considered, including the forces that result from such airflow and the effect these forces have on the aircraft, during steady flight and during manoeuvres. Although there are various kinds of pressure, pilots are mainly concerned with atmospheric pressure. It is one of the basic factors in weather changes, helps to lift an aircraft, and actuates some of the important flight instruments. The pressure of the atmosphere varies with time and location. Due to the changing atmospheric pressure, a standard reference was developed. The International Civil Aviation Organization (ICAO) has established this as a worldwide standard, and it is often referred to as International Standard Atmosphere (ISA) or ICAO Standard Atmosphere. Large modern passenger aircraft can weigh in excess of five hundred thousand kilograms when they fly with a full fuel and passenger load, yet this combined mass is lifted into the air with apparent ease. Modern jet fighter aircraft can exceed the speed of sound and are very manoeuvrable. Thrust, drag, lift, and weight are forces that act upon all aircraft in flight. Understanding how these forces work and knowing how to control them with the use of power and flight controls are essential to flight. Task 1 A, The international standard atmosphere is an atmospheric model of how the pressure, temperature, density and viscosity of the earths atmosphere change over a wide range of altitudes. ISA model divides the atmosphere into layers. http://en.citizendium.org/images/thumb/2/26/AtmTempProfile.png/350px-AtmTempProfile.png Atmospheric Layers Figure 1 source= http://www.google.co.uk/imgres?q=international+standard+atmosphere+diagramum=1hl=ensa=Nbiw=1366bih=667tbm=ischtbnid=IWsOmm4pNQN12M:imgrefurl=http://en.citizendium.org/wiki/Atmospheric_lapse_ratedocid=IVZzKSSCCNR_KMimgurl=http://en.citizendium.org/images/thumb/2/26/AtmTempProfile.png/350px-AtmTempProfile.pngw=350h=385ei=aImJUMrXNo2Y1AWj04G4Dwzoom=1iact=hcvpx=369vpy=138dur=273hovh=207hovw=188tx=145ty=90sig=113637047184909608346page=1tbnh=137tbnw=125start=0ndsp=19ved=1t:429,r:1,s:0,i:72 Troposphere Troposphere contains about 80% of atmospheres mass 99 % of its water vapour and aerosol. The temperature of the troposphere generally decreases as the altitude increases. The reason for the temperature difference is that the absorption of the suns energy occurs at the top of the atmosphere cooling the Earth, this process maintaining the overall heat balance of the Earth. Stratosphere Stratosphere is the second important layer of the atmosphere. It is separated from troposphere by tropopause. It takes about 12 to 50km of the atmosphere. The temperature increases as the altitude increase. At the top of the stratosphere the thin air may attain temperature close to 0c. this is happening because of the absorption of UV radiation from the sun by the ozone layer. Such a temperature profile creates very stable atmospheric conditions and the stratospheric lacks the air turbulence that is so prevalent in the troposphere. Stratosphere is completely free of clouds and any other forms of weather. This layer is very good for the flights to fly as it is above stormy weather and has strong, steady and horizontal winds. Stratosphere is separated from the mesosphere by the stratopause. Mesosphere This layer is the third highest layer of the atmosphere. This layer takes 50 to 80km above the surface of the Earth. It is separated from the stratosphere by stratopause and from the thermosphere by mesopause. Temperature drops when the altitude increases to about -100. Mesosphere is the coldest of all the layers as it is colder than Antarctica. This layer can freeze water vapour into ice clouds so that when the sunlight hits them you can see it after sunset. It is also the layer where the meteors burns up while entering the Earths atmosphere. Thermosphere Thermosphere is the outer layer of the atmosphere. Mesopause separates mesosphere from thermosphere. In this layer the temperature rise continually to well beyond 1000 The few molecules that are in this layer receives an extraordinary amount of energy from the sun therefore warms up the layer making it hotter. Air temperature however is the measure of the kinetic energy of air molecules, not of the total energy stored by the air so the air is so thin within the thermosphere, such temperature values is not comparable to other layers. Although the temperature is very high we would feel very cold because the total energy of only a few air molecules residing there wouldnt be enough to transfer any heat to our skin. Ionosphere After thermosphere its Ionosphere. This area is full of ionized air extending from 80km above the Earths surface altitudes of 600km and more. Technically Inosphere is not layer.In this region/area the suns energy breaks molecules and atoms of air as the energy is so strong and hot leaving ions and free floating electrons. Ionisation of the air molecules is produced by UV radiation, other radiation from sun and cosmic rays. Ionosphere is the region where aurora appears.

It is a very smooth and uninterrupted flow of air over the contour of the wings and other parts of an aircraft. Laminar is found at the front of the streamlined body. An air foil is designed for minimum drag and uninterrupted flow of the boundary layer is called a laminar air foil. The pattern of the flow involves of layers. Particles in each layer do not interfere with other particles in the other layer which makes it smooth flowing layers. There is no difference in velocity between the layers. Boundary layers are thinner at the leading edge of the aircraft wing and thicker towards the trailing edge, such boundary has laminar flow in the leading portion and turbulent flow at the trailing portion. There is more drag than laminar. In this flow the direction and velocity changes continuously. Particles move opposite to other particles causing collision which makes turbulence. The trust need to be more counteract the flow of turbulence. Reynolds number is dimensionless quantity associated with the smoothness of flow of air/fluid. At low velocity the flow of a fluid/gas is laminar; the fluid/gas in the layers of laminar flow gives rise to viscosity. As the gas flows more rapidly, it reaches a velocity known as critical velocity. This is when the motion changes from laminar to turbulent. Viscosity is the resistance of a fluid to flow. The coefficient of viscosity of gases increases with increasing temperature. Task2 A, Bernoullis principle As the velocity of the gas increases the pressure exerted by that fluid decreases. The aeroplane gets part of the lift from Bernoullis principles. This principle says that increased air velocity produces. When the Bernoullis principle is applied the fluid has these qualities Fluid flows more smoothly Fluid flows without any swirls(eddies) Fluid flows everywhere through the pipe Fluid has same density everywhere As the fluid passes through a narrow or wide pipe, the velocity and pressure of the fluid vary. As the fluid flows through a narrow pipe the flow quickly. This principle says that fluid flows more quickly through the narrow section, the pressure actually decreases than increasing. Air passes faster over the top of the cambered wing and results in lower pressure. The top of the wing is curved, the air that passes over the top of the wing moves faster because it travels a greater distance in the same amount of time as compared to the air that passes underneath the wing. Lift is created because the air under the wing is slower and exerts higher air pressure so the difference in the pressure creates the lift. Venturi principle An inverse association of gas pressure, velocity of flow, and restriction of passage. This principle states that the pressure drop distal to a restriction can nearly be restored to the pre restriction pressure if there is a dilation of the passage immediately distal to the stenos is, with an angle of divergence not exceeding 15 degrees. In venture tube the area decreases the velocity increases and the pressure decreases, and vice versa as well. So the difference in pressure creates lift. B, Total drag Total drag is the sum of all of the aerodynamic forces which act parallel to, and opposite to, the direction of flight also it is the total resistance to the motion of the aircraft through the air.it is the sum of other drags acting on the aeroplane which are parasite drag and induced drag. Induced drag is the drag created by the vortices at the tip of an aircrafts wing. Induced drag is the drag due to lift. The high pressure underneath the wing causes the airflow at the tips of the wings to curl around from bottom to top in circular ms in a trailing vortex. Induced drag increases in direct proportion to increases in the angle of attack. the circular motion creates a change in the angle of attack near the wing tip which causes an increase in drag. The greater the angle of attack up to the critical angle, the greater the amount of lift developed and the greater the induced drag. parasite drag the parasite drag of a airplane in the cruise configuration primarily of the skin friction, roughness and pressure drag of the major components. There is usually some additional parasite drag due to such things as fuselage upsweep, control surface gaps, base areas and other extraneous items. Since most of the elements that make up the total parasite drag are dependent on Reynolds number and since some are dependent on mach number, it is necessary to specify the conditions under which the parasite drag is to be evaluated. In the method of these notes, the conditions selected are the mach number and the Reynolds number corresponding to the flight condition of interest. This drag comprises skin, form drag and interference drag. Skin friction drag is a friction force between an object and the air through which it is moving produce skin friction drag. Form drag is when the airflow actually separates from the surface, eddies are formed and the streamline flow is disturbed. The turbulent wa ke so formed increase drag this is form drag. Interference drag is caused by flow interference at the wing and other such junctions. This interference leads to the modification of boundary layers and creates a greater pressure difference between the for and after area on the surface concerns. This in turn leads to greater total drag. Fairing or additional fillets are used to streamline these intersections and decrease interference drag.

It doesnt change significantly with an angle of attack of the airfoil section, but increase moderately as airspeed increases. Is the drag incurred as a result of production of lift. Higher angles of attack which produced more lift also produce increased induced drag. In rotary wing aircraft induced drag decreased aircraft airspeed. The induced drag is the portion of the total aerodynamic force which is oriented in the direction opposing the movement of the airfoil.

Art History of Central America :: essays papers

Art History of central America Chavin de Huantar was located in Peru and developed around 900 B.C. late in the Initial Period. At an elevation of 3,150 m., Chavin de Huantar was situated at the bottom of Cordillera Blanca’s eastern slopes, approximately halfway between tropical forests and coastal plains. At the intersection of major routes, Chavin de Huantar was in the position to control the routes, increase their exchange with others, and receive goods that were not natural to their area. Chavin de Huantar was an agricultural society, home to a fairly large population. The Old Temple was built during the late Initial Period and it was the â€Å"center of supernatural power and authority.† It was a U-shaped platform opening to the east with a circular courtyard in the center. The Old Temple also consisted of numerous passageways and chambers underground called galleries. These galleries were used for storage chambers, religious rites, and possibly temporary or permanent living for small groups working with temple activities. The Lanzon Gallery is located at the very center of the Old Temple. It was where the sculpture of the Lanzon was found. The Lanzon, the supreme deity of Chavin de Huantar, is anthropomorphic. With its feline head and human body, it has intertwined the feline deity of Chavin de Huantar and the shaman of the pre-Chavin period. For the pre-Chavin period, the object of worship was the feline, but this was gradually changed. By the time of Chavin de Huantar, it was anthropomorphic. During this time, it was believed that priests could become jaguars and interact with the supernatural forces. This was achieved by taking hallucinogenic drugs as part of rituals at the Old Temple. There are many sculptures that decorate the Old Temple depicting the transformation of the priests. There have been mortars, pestles, conch-shell trumpets, and many other items with anthropomorphic design found and thought to be associated with Chavin rituals. The New Temple â€Å"forms a continuum† with the Old Temple. The same belief system continues and there is evidence of the same rituals. The New Temple also has galleries and plazas. The Lanzon, although in a different stance, continues to be a symbol of mediation and harmony. The right hand of the deity holds a Strombus shell, for male forces, and the left hand holds a Spondylus shell, for the female forces. The New Temple, however, did not replace the Old Temple.

Black Holes: The Power Source for Future Space Travel? :: Space Exploration Essays

Everyone knows that the spaceships in Star Trek that travel faster than the speed of light are mere science fiction. According to Einstein's theory of relativity, if an object reached the speed of light, its mass would be immediately transformed into energy. Currently our spaceships can not even reach mars in less than five years. Now, with modern theories of black holes, trips to other solar systems may be possible at nearly the speed of light. Black holes were only proven to exist within the last twenty-five years and were only really considered to exist for the last seventy-five years. Yet these recently discovered objects could be the energy revolution of the future, much like nuclear power was in the sixties. Black holes generate tremendous amounts of energy in several different ways, and so can be harnessed in several ways to generate usable power. In order to understand how energy can be created from black holes, one must first have an understanding of black holes themselves. Black holes are formed by matter being crushed within a certain radius (call the Shwarzchild radius or event horizon). This radius can be calculated by the equation r = 2GM / c2, were G is Newton's gravitational constant, c is the speed of light, and M is the mass of the black hole. This shows that the density within the event horizon, which is equal to 3M / 4?r2 for a spherical object, will actually decrease as the mass increases. The gravitational field around a black hole will act same as an object of identical mass, so "if the sun were to suddenly †¦ [become] a black hole †¦ would the earth go plummeting into it? No, it would continue on its orbit †¦ things just get interesting close to the black hole" (Jebornak, 1998). There are three types of black holes that scientist currently believe are capable of becoming future power sources: Schwarzschild black holes, Newmann black holes, and primordial black holes. Schwarzschild black holes are the simplest black holes because they do not rotate and have no charge. The Newmann black hole, on the other hand, rotates and has a charge, but like the Schwarzschild black hole can have varying masses from a couple times our sun's mass to several billion times the mass of our sun. Primordial black holes were first theorized about "In the year 1973 [by] Stephen W.

Fear of Death

Some old people are oppressed by the fear of death. In the young there is a justification for this feeling. Young men who have reason to fear that they will be killed in battle may justifiably feel bitter in the thought that they have been cheated of the best things that life has to offer. But in an old man who has known human joys and sorrows, and has achieved whatever work it was in him to do, the fear of death is somewhat abject and ignoble.The best way to overcome it – as at least it seems to me – is to make your interests gradually wider and more impersonal, until bit by bit the walls of the ego recede, and your life becomes increasingly merged in the universal life. An individual human existence should be like a river – small at first, narrowly contained within its banks, and rushing passionately past boulders and over waterfalls. Gradually the river grows wider, the banks recede, the waters flow more quietly, and in the end, without any visible break, they become merged in the sea, and painlessly lose their individual being.The man who, in old age, can see his life in this way, will not suffer from the fear of death, since the things he cares for will continue. And if, with the decay of vitality, weariness increases, the thought of rest will be not unwelcome. I should wish to die while still at work, knowing that others will carry on what I can no longer do, and content in the thought that what was possible has been done.

Psychology Case Studies Essay

According to the diathesis-stress model there are many things that seem to be able to relate to the anxiety disorder that Winnie has. As for the biological factors some of the issues could have arise from Winnie spending her first three weeks of life in the neonatal intensive care unit where it would be impossible for her to bond with her mom and have the typical bonding experiences that occur with a newborn. Therefore Winnie would have a harder time with feeling security and could have some separation anxiety as part of her biological make up of not being with her parents during those first few weeks for bonding time. Biologically it could be suggested that since she was having a hard time breathing and having the â€Å"blue spells† that her mother talked about there could have also been some brain development or psychological damage from this. As for life experiences being factored into her issues with social anxiety there are many different experiences in her life that could be a part of this. One of these issues could have been the fact that she was not with her parents and in the intensive care unit. There are different studies and theories as to whether or not this would be considered a biological or a life experience factor in this case, for these purposes it is being left as a biological factor. When Winnie was very young and her mother had the two miscarriages and suffered depression and then suffered some side effects of the medications there would have been strain on Winnie as her mother would not have acted the same as she did prior to these instances. For a developing child at these ages there are many reasons to believe that this could cause permanent damages for the child’s confidence and ability to feel secure as this is the time when so many developments are taking place. Also the experience of Winnie’s friend moving away could have caused some of the social anxiety and some of the issues with her innate fear that something would happen to her mother when she was not around. These different factors could explain her social anxiety through the Diathesis-stress model. 2. The separation anxiety disorder can be explained through the behavioral perspective. The explanation would be that there are so many various factors that could affect a child which would have caused her to have these negative learned behaviors. When the mother was depressed and then agitated from the medications the child could have learned to stay quiet and to keep to herself in order to be able to manage her feelings and still have her mother be happy around her. Another explanation on this theory could have been that the mother might have rewarded the child for quiet play. When the child’s friend suddenly moved away the learned behavior might have been that someone can leave and never return. This would have taught the child to keep her mother close by in order to ensure that her mother would not be leaving and never coming back. Also when the mother gave her more attention for throwing a fit the first time then it would explain how she ended up throwing fits each day as she was hoping to be rewarded by getting that extra time with her mother. As for her overall separation anxiety and treatment for it, it could be suggested that the child be enrolled in some play therapy where she could discuss her real fears and the sources of her fears with the therapist in order to be able to reassure her that things were okay. Also there could be some indications that the child would also benefit from a very set and scheduled routine and some reassurance from her mother in the form of a reward of some sort. The reward would be to reinforce positive behaviors for instance if she was able to not throw a fit and if she were able to be okay when her mother left her then she would be able to manage her feelings in some positive manner (Cliff’s Notes Behavioral†¦). As for the cognitive perspective and the issue of Winnie’s separation anxiety, there are many factors that can be examined in order to explain the problems. The way that this perspective could be applied is through the ways that Winnie is interpreting and looking at things having to do with the separation of her mother. Since Winnie has spent her primary amount of time with her mother there is reason to believe that some of the problems could have to do with her father not being around her perception on what he is doing when he is not home since he is admittedly thinking about work much of the time when at home. Her perception might be that he is not really there for her and that he is not really able to be there for her on a regular basis. She might have a larger fear from some of the other issues occurring like that if her mother leaves she might not ever see her again after her perception that her friend left and she didn’t see her either. As for her fear of something happening to her mother while she is gone, there are many reasons to think that her mother could have a hard time without her. It could be questioned as to why she has this fear if something has happened to someone she knows or the content of the television programming that is being watched around her. Some of these things are because there seems to be a lot more to her perceptions and why she is so fearful of losing her mother. Some treatments that might be suggested in this case are family therapy. There could be a lot gained from Winnie understanding that both of her parents care about her well being and that both of them are dedicated to taking care of her. Some other treatment could be to monitor the family’s television and to not allow Winnie to be in the room when viewing any type of movie dealing with death and also there could be some benefits from Winnie spending some quality time with her father (Garvy and Spoor). The psychodynamic perspective for child development would suggest that the separation anxiety as coming from Winnie’s infancy and her being separated from her parents during her first crucial weeks of life. This perspective would suggest that Winnie was unable to be without her parents and had such a large fear of being away from them because she was unable to bond with them during the first few weeks of her life and she had to be alone during this time as well. Also the separation of Winnie from her young friend would suggest that there were more issues to this than originally thought as there were many times when Winnie would not have been able to process these thoughts. Also Winnie’s mother had commented that Winnie did not talk about this friend moving and not having this friend around. This is crucial as there are many reasons to believe that Winnie should have in some way expressed that she was upset about being separated from her friend and that she needed some reassurance which she did not get during this time as she had not asked for it. Through this perspective it is possible to conclude that Winnie would not have understood or known what to ask for in this situation (Van Morgan 2009).
