...Project Design Plan The experiment is designed to test how the degree of inflation in a basketball directly relates to its rebound height. My intent is to determine how the air pressure can negatively affect the ball with too short or high a rebound. This is relevant to basketball players because they need to maintain control over the ball. Too little inflation and the ball will not bounce high enough for them during dribbling to continue forward at maximum speed to score or they will not be able to pass the ball on a bounce because the ball may not make it to the next player. Too much inflation and the ball may become erratic and not go where it is intended during a pass and will be much more difficult to handle while dribbling. Literature Review The NBA (National Basketball Association) is the governing body for professional basketball in North America. In order for a basketball to meet regulation standards for professional games, the NBA states on page ten of their rule book in section II.f.(1) “ The ball shall be an officially approved NBA ball between 7 ½ and 8 ½ pounds of pressure” (National Basketball Association, 2013). The NCAA (National Collegiate Athletic Association) states in its rulebook in section 16, article 7 that “when [the ball] is dropped to the playing surface from a height of 6 feet measured to the bottom of the ball, it will rebound to a height, measured to the top of the ball, of not less than 49 inches when it strikes its least resilient spot nor...

...treatment. The series of medical experiments took place in the early 1940’s; during WWII and the Holocaust. In these experiments patients suffered indescribable pain. Typically the experiments resulted in death, trauma, disfiguration and permanent disability. There was as, many as thirty different kinds of tests including: the freezing, the high altitude and the hemorrhage experiments. The Nazi physicians did not care about the patients undergoing tests, they only cared about getting new information to improve the German military. Consent was never given for any of the patients, all patients were forced into doing the inhumane tests created by the Nazis’s....

...Kyndon Boatman How does a basketball’s bounce change due to surface Research Summary Will the surface affect a bouncing ball- When a ball bounces it uses kinetic and potential. When it is in your hand it is potential when it hits the ground it is kinetic. On average there are 15 dribbles in 1 trip down the court,so dribbling is an important part of the game. If you drop a ball from a set distance and it is regulation air pressure on a gym wood surface it will bounce back up ⅔ of the height you dropped it. When a basketball hits the ground (and as it flies through the air), it actually transforms some of its energy to another form. If players do not put enough energy back into the ball, they will not be able to dribble it effectively. Some...

...matter if an object was stationary and air was blown was over the object or if the object was moving through the air. The resultant forces over the object would be the same. The idea of blowing air over an object and determining the forces lead to the invention of wind tunnel. As the name suggests, a wind-tunnel is a cylindrical tunnel in which air is blown from one side by a huge fan at high speeds. The middle part of the tunnel is called as throat. It is the place where the test model is placed. Various sensors are attached to the test model and the data is collected in the room near it. The data collected issued to reduce the aerodynamic drag and minimize fuel consumption and also increase the speed of the cars, trucks, planes, etc. also aerodynamic properties like lift, drag, forces, moments are measured with the use of wind-tunnel. In wind-tunnel air is blown over the test model which is kept stationary at the throat. This will produce the same effect as it would be produced if the vehicle is moving at high speeds on a road. For more accurate results the tunnel is sometimes equipped with rolling road to prevent the boundary layer forming on the floor which may affect the test results. * What are wind tunnels? Just as its name suggests, a wind tunnel is a tube or tunnel that has man-made windblown through it at a certain speed. Scientists and engineers put a model of an airplane in the tunnel and then study the way air moves around the model. By looking at...

...unethical practices where the research participants lacked adequate protection. To protect human research participants from undo harm, biomedical researchers must follow the four basic ethical principles on which standards of ethical research are based: autonomy, beneficence, nonmaleficence, and justice. Such ethical requirements on biomedical research are found in documents such as the Declaration of Helsinki or the Belmont Report. The four principles and Institutional Review Boards (IRBs) are the principal regulations and ethical protocols when conducted human research. In the United States, the National Institute of Health (NIH) is the primary agency responsible in enforcing ethic in human research but the IRBs falls within the authority of the Food and Drug Administration (FDA). In other countries, different names might be used, such as research ethics committees or ethics review committees. Where ever human research is conducted, either within the US regulations or internationally, it should be conducted only after an appropriate ethical reviewed has occurred. Whether ethical standards are practice according to...

...Discipline Assignment 3 Conformity, Obedience and authority 27th November 2015 In this assignment I will outline the terms conformity and obedience using references to the public services. I will then explain why they are important and relate them to Asch, Milgram and Zimbardo’s studies. Finally I will describe authority and its relation to the public services. 3.1 Conformity Conformity is when someone acts or behaves in accordance with another/ prevailing social standards, attitudes or practices. Following social norms (the unwritten rules of society) is a type of conformity. Social Norms are a common practise which everyone takes part in, even if it is unintentional. An example of a social norm is going to the back of a que, instead of walking past everyone to the front as we know it would not be accepted by others to do so. Most people conform to fit in or be liked by everyone. It is most common for people with low self-esteem to conform as there is a need for social approval, people who do not integrate tend to stand out and feel lonely in today’s society so they believe they need to conform to become a part of a group. Conformity takes place in every discipline environments, especially the uniformed public services. The Army, for example, issue their soldiers all with the same uniform and administer them with a daily routine. This type of conformity is so every soldier is treated equally and gain similar skill sets and knowledge. The routine the soldiers are given...

...environmental concerns surrounding hydraulic fracture drilling (fracking) for gas? With the fast expansion of shale gas drilling operations and reduced federal regulations has placed our environment in harm’s way. If the environment is in trouble so are the health of humans and animals. Without proven scientific studies, the gas drilling boom sweeping the U.S. and the world will remain an uncontrolled health experiment of enormous scale. There is much controversy surrounding the impact of this type of drilling on air and water quality, placing gas and oil companies against individuals and groups concerned with environmental and health protection. It is time for federal regulation and tougher oversight control of this out of control drilling. Hydraulic Fracturing; Fracking 3 What Is Fracking Hydraulic fracturing or hydrofracking better known as fracking is a method of mining for natural gas which greatly increases the efficiency of extracting shale gas from deep underground. This method has been used since the 1940’s and perfected by Floyd Farris of the Standard Oil and Gas Corporation. In the beginning the process was simple in its technique of introducing non-explosive fluids (acids) under pressure of sand and water to cause fractures in gas shale deposits. (Montgomery & B.Smith, 2010) As this method was improved and put into commercial use, gas extraction...

...well as powerful psychodynamic effects (such as euphoria, increased alertness, and a sense of relaxation). Nicotine is also powerfully addictive. Tar is a sticky substance that forms into deposits in the lungs, causing lung cancer andrespiratory distress. Carbon monoxide limits the amount of oxygen that the red blood cells can convey throughout your body. Also, it may damage the inner walls of the arteries,which allows fat to build up in them. Carbon Monoxide (CO) is a colorless, odorless, tasteless gas that is a small part of the air we breathe. There are many sources of Carbon Monoxide such as incinerators, car exhaust and gas furnaces. Ammonia: A colorless gas with a very sharp odor. Made both by humans and by nature, ammonia dissolves easily in water and evaporates quickly. Liquid ammonia is found in many household cleaners. Ammonia is irritating to the skin, eyes, nose, throat, and lungs. Exposure to high concentrations in the air can severely burn the skin, eyes, throat, or lungs. In extreme cases, blindness, lung damage, or death can occur. Breathing lower concentrations causes coughing and nose and throat irritation. Swallowing ammonia may burn the mouth, throat, and stomach. Why People Smoke Most people...

...identified. Changes in executive leadership can and usually do pose challenges for an organization. In this regard, Wal-Mart is no different. Lee Scott took the post as CEO of Wal-Mart in January 2000. Some of his challenges throughout his reign as CEO were ethical issues, personnel dilemmas, health insurance reform, and pressures from external groups. Ethics guides the managers’ decision making process by determining moral awareness, judgment, and character. The manager must acknowledge that an ethical issue exists, determine a solution that is within morals, and have the ability to carry out their ethical decisions. Managers must also wear a “veil of ignorance”, a term based on John Rawls experiment. This means that managers must place themselves in the group that the decision will negatively affect and weigh the decision. Ethical decision making also involves using the problem solving method. Ethics is important to the managers’ decision making process, because it can have costly consequences. The cost of unethical decision making include government fines, decline of employee commitment and morale, and an increase in government regulation. Unfortunately, Scott encountered some of these costs during his tenure as CEO. Scott brought...

...A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p–n junction diode, which emits light when activated.[4]When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor. An LED is often small in area (less than 1 mm2) and integrated optical components may be used to shape its radiation pattern.[5] Appearing as practical electronic components in 1962,[6] the earliest LEDs emitted low-intensity infrared light. Infrared LEDs are still frequently used as transmitting elements in remote-control circuits, such as those in remote controls for a wide variety of consumer electronics. The first visible-light LEDs were also of low intensity, and limited to red. Modern LEDs are available across the visible,ultraviolet, and infrared wavelengths, with very high brightness. Early LEDs were often used as indicator lamps for electronic devices, replacing small incandescent bulbs. They were soon packaged into numeric readouts in the form of seven-segment displays, and were commonly seen in digital clocks. Recent developments in LEDs permit them to be used in environmental and task lighting. LEDs have many advantages over incandescent light sources including lower energy consumption, longer lifetime...
