intake design analysis. Supersonic and hypersonic flights often make use of a ramjet engine during the cruise phase of the flight. The design of the intake affects important variables of the ramjet engine, namely Mach number distribution, formation of shocks and pressure distribution. Analysis of a normal intake design provides lower than optimal pressure to the combustion chamber. A geometric dimension modification on the intake, i.e. lengthening of the nosecone significantly improves the resultant pressure
"sound barrier" was finally removed in 1947, when the Captain Yaeger flew the Bell X-1 at a speed slightly above Mach 1 for few seconds, producing the famous and long-awaited sonic boom (caused by an impulsive pressure change created by the sonic waves detaching from the aircraft), music for the scientists attending that historical moment, but current nightmare for the 21st Century supersonic vehicles' designers [8]. Since the first wind tunnel investigations on high speed flow over a stationary
A Winston S. Churchill once said,” I have nothing to offer but blood, toil, tears and sweat”. In the novel Flood Tide by Clive Cussler, Dirk Pitt shows he is always ready for whatever may come next, and he will attempt to accomplish it to the best of his ability. Dirk Pitt continually exemplifies the true meaning of having helpfulness, bravery, and intelligence in his everyday life. Dirk Pitt, a Special Projects Director at NUMA, displays many important traits one of which is his helpfulness towards
The aviation industry is constantly evolving as each day brings new and better technology than the last. As a student pursuing a future career in the aviation industry it is very important to understand all the technologies being used within it—especially those related directly to the flight aspect. This CNN article contains a lot of valuable information regarding the Concorde as the first commercial plane with supersonic capabilities—as well as the improvements and the future technological advancements
Shock is a feeling of fascination and excitement mixed with anxiety, tension, suspense and surprise developed from an unpredictable, mysterious, and engaging source of entertainment (Merriam-Webster). Shock can occur whenever there is a perceived suspended drama, with tension, suspense or surprise being the primary emotions felt by the audience as part of the situation (Dirks). However, the term is most often used in regards to an audience’s perception in dramatic works such as film. One often experiences

This results in an increased risk of plantar fasciitis(inflammation of the tendons in the bottom of the foot), calf strains, and Illotibial Band Syndrome, otherwise known as ITBS, which causes pain and inflammation along the ... ... middle of paper ... ...cause their ability to control over pronation and shock absorption is lacking.

Comparing The Lottery and What A Thought The short stories I have chosen were "The Lottery" and "What A Thought" by Shirley Jackson. Shirley Jackson is considered a morbid writer due to the fact that she writes her stories with the intent to shock her readers into seeing the truth behind human nature. Her work deals with an evil presence in everyday life. "The Lottery" is a chilling tale of an everyday town and their annual lottery. It shows how cruel a town can be in protecting their
Cultural Shock in Chekhov's The Cherry Orchard Anton Chekhov's The Cherry Orchard projects the cultural conflict of the turn of the twentieth century of Russia. With a historical allusion, Chekhov exhibited the changing Russia with "slice of life" in his play. The Cherry Orchard is not only a depiction of Russian life but also an understatement of changing traditional value. Cultural conflict itself is an abstraction. To explain it, it is the traditional culture that is unable to resist the
Presence of Vibrations in Mechanical Systems – Machine Health monitoring Vibrations are found in most machines especially those that have rotating or reciprocating systems. Some of the vibrations are normal to the standard operation of the machine but some may be the result of mechanical faults including mass unbalance, coupling misalignment, mechanical looseness, and many other causes. So unbalance is the cause of most of the abnormal machine vibration. For example an unbalanced rotor always causes
I could use this information that I learned about essentialism to my everyday life. If I want something to taste better I can manipulate my mind or other peoples minds by simply decoying an object. This can allow people to get on my good side whether they are rich or poor. Knowing how to pleasure oneself and others is a good strategy not only in social encounters, but also in work or school environments. This also helps to give a better understanding on why elders and museum historians find certain
Background Hypovolemic shock in trauma victims is a life-threatening condition. In the prehospital environment, EMS providers treat hypovolemic shock by attempting to control hemorrhage and by providing fluid resuscitation with crystalloid solutions. It has long been debated which crystalloid solution provides the ideal fluid resuscitation for victims of traumatic hypovolemic shock; whether it be solutions with similar concentration to human blood (isotonic solutions), or whether fluids should be
as belonging to both Pavlovian and operant influences, thus the nomenclature two-factor theory. In the instance of a bright light presented prior to a shock, the shock is then escaped, creating a reinforcer—the shock is disrupted. As each shock is escaped, a Pavlovian conditioning begins to form through the association of the light with the shock until finally a pairing is formed. At this stage the light has come to represent fear to the subject, who will now seek to escape the fear-associated CS
Fluids or inotrophes in undifferentiated shock-Review of Case series Introduction There is a long-standing debate as to the most accurate method of determining the volume status of a critically ill patient,as well as the physiological ability to respond to fluid therapy. In the assessment of a critically ill patient receiving volume replacement, a wide variability of assessment options are available; however, the current literature has yet to determine which method is the best. This case series
to inescapable and unavoidable electric shocks in one situation later failed to learn to escape shock in a different situation where escape was possible” (Maier, 1967 ). Dogs were placed in an area where shocks could be avoided and dogs showed that they eventually learned how to escape the shocks every time. He placed dogs during his experiment in the line of shocks that were random and unable to avoid. The dogs showed Learned Helplessness when the last shocks were avoidable, but didn’t make any move

Finally getting home to open the fridge and noticing that the chicken pot pie is gone and wondering which roommate ate the last slice. In that moment anger, confusion, and shock runs through ones body. That is exactly how the loving, devoting, and caring wife, Mary Maloney felt when her husband made an unexpected decision
The Features of Conformity and Obedience Conformity: Debra Gray defines conformity as “A change in behaviour in response to real or imagined group pressure when there is neither direct request to comply with the group nor any reason to justify the behaviour change”. Conformity is the degree to which members of a group will change their behaviour, views and attitudes to fit the views of the group. The group can influence members via unconscious processes or via overt social pressure on individuals
gratuitous or whether it is a legitimate artistic expression. There can be no doubt that Michael Ondaatje's long poem The Collected Works of Billy the Kid is a violent work, but certain factors should be kept in mind before passing it off as an attempt to shock and titillate; certainly, the poem does both of these, but they are not the primary purpose of the work. For one thing, social context needs to be considered; Billy lived in the "Wild West", a time associated with range wars, shoot-outs and great train
In Hiding - Original Writing I had to find somewhere to hide. If I didn’t, I would be caught. I could hear the allies in the distance. I had been separated. My adrenaline was rushing. I knew I could not stop under any circumstances, my time was running out. The enemy could be on my trail in seconds rather than minutes. Ahead I could see a brick wall with a massive, dense bush just in front of it. I didn’t want to risk going on. This would have to do. The gloominess of the early evening
