...which is to be cut, and the tool must be able to withstand the heat generated in the metal-cutting process. Also, the tool must have a specific geometry, with clearance angles designed so that the cutting edge can contact the workpiece without the rest of the tool dragging on the workpiece surface. The angle of the cutting face is also important, as is the flute width, number of flutes or teeth, and margin size. In order to have a long working life, all of the above must be optimized, plus the speeds and feeds at which the tool is run. Spur: Spur gears or straight-cut gears are the simplest type of gear. They consist of a cylinder or disk with the teeth projecting radially, and although they are not straight-sided in form, the edge of each tooth is straight and aligned parallel to the axis of rotation. These gears can be meshed together correctly only if they are fitted to parallel shafts Helical: Helical gears offer a refinement over spur gears. The leading edges of the teeth are not parallel to the axis of rotation, but are set at an angle. Since the gear is curved, this angling causes the tooth shape to be a segment of a helix. Helical gears can be meshed in a parallel or crossed orientations. The former refers to when the shafts are parallel to each other; this is the most common orientation. In the latter, the shafts are non-parallel, and in this configuration are sometimes known as "skew gears"....

...From time to time human beings experience health challenges, whether physical or mental. On its part, medical practice has made considerable progress towards combating or controlling many of these challenges. It is through research that the nature, symptoms and effects of ailments can be ascertained and remedies discovered. Medical researchers engage in both therapeutic and non-therapeutic research. Therapeutic research is that carried out with the purpose of treating disease. On the other hand, non-therapeutic research is aimed at 76 Adebayo A. Ogungbure furthering the frontiers of knowledge about human health. Furthermore, researchers and physicians often use human beings as objects of scientific investigation, raising certain ethical concerns, including the issue of informed consent and how consent is obtained, selection of participants in research, the welfare of human subjects involved in a research project, what the goals of research ought to be, and what ought to constitute proper procedure for an ethical research. These issues are central to an aspect of applied ethics which is now commonly referred to as research ethics. The aim of research ethics is to ensure that research projects involving human subjects are carried out without causing harm to the subjects involved. In addition, it provides a sort of regulatory framework which ensures that human participants in research are not exploited either physically or psychologically. The need for ethical guidelines...

Tech Student, Mechanical Engineering Department NRIIST BHOPAL (M.P) India Email: 1jitendra.me@gmail.com, 2chandraprakash210@gmail.com Abstract: Gears which are most widely used for transmission of power from one shaft to the shaft are considered in this paper for analysis and hence predict the stresses in them using the most versatile numerical techniques in practice, the Finite Element Method (FEM). In all spur gears are the most preferred type of gear because of simplicity of use & manufacturing with high degree of transmission efficiency. They develop high stress concentration at the root and the point of contact...

...As you get older your brain decreases and gets weaker over time. A way to help this problem not happen is to exercise. Exercise keeps the mind and body active and improves the overall function of your body. Exercise spurs brain growth. It boosts brain-building hormones. It improves your brain’s executive function. Lastly it can reduce and prevent depression through steady activity a few times a week. Previously I said exercise spurs brain growth, growth of new brains cells slow down and don’t reproduce as fast. According to the article it states, “...our brain tissue actually shrinks. Exercise may be able to reverse that trend.” That’s a possible way that we can prevent or slow down the major decrease in brain growth. Exercise is a simple way to improve brain growth and everyone can become involved into it....

...Chris Uhle 11-17-2014 Global Sports Business Moneyball When Michael Lewis’ Moneyball was released it officially announced Billy Beane’s new way of thinking to the rest of the world. Before the book was written, only a small group of people really had a full understanding of how analytics were changing the evaluation process in the sport of baseball. Billy Beane had always been using unconventional ways in finding undervalued players, but Lewis’ book brought his in depth strategy to the forefront of the sport. In 2011, Brad Pitt and Jonah Hill starred in the film Moneyball. The movie did keep the same basic storyline as the book, however there were many differences between the two. One of the biggest disparities between the book and the film that I saw was in the way the film portrayed how the idea of Moneyball started. One of the first scenes in the movie has Billy Beane in Cleveland to discuss trade possibilities with the Indians. Beane notices that one of Shapiro’s (Cleveland GM) assistants is dictating who is tradable and confronts him after the meeting. The movie says this is the first time Beane is introduced to the world of sabermetrics and advanced analytics. While this makes for a good storyline, Billy Beane actually got the idea from former A’s GM, Sandy Alderson, not Peter Brand like in movie. This is a great exaggeration from the book as Brand is basically credited with the entire idea. In fact, Peter Brand was not even the real name of Beane’s assistant GM...

...10 All-NBA teams, and six All-Defensive teams, and is the Cavaliers' all-time leading scorer. James played high school basketball at St. Vincent–St. Mary High School in his hometown of Akron, Ohio, where he was highly promoted in the national media as a future NBA superstar. After graduating, he was selected with the first overall pick in the 2003 NBA draft by the Cavaliers. James led Cleveland to the franchise's first Finals appearance in 2007, losing to the San Antonio Spurs. In 2010, he left the Cavaliers for the Miami Heat in a highly publicized ESPN special titled "The Decision". In his first season in Miami, the Heat reached the Finals but lost to the Dallas Mavericks. James won his first championship in 2012 when Miami defeated the Oklahoma City Thunder. In 2013, he led the Heat on a 27-game winning streak, the second longest in league history. Miami also won its second consecutive title that year. In 2014, the Heat reached the Finals for the fourth consecutive year, eventually losing to the Spurs. Following Miami's defeat, James opted out of his contract with the Heat and rejoined the Cavaliers. Off the court, James has accumulated considerable wealth and fame as a result of numerous endorsement deals. His public life has been the subject of much scrutiny and he has been ranked as one of America's most influential and...

...In Latin America, the popularity of the sport is growing rapidly and the most recent of talent into the NBA is migrating from Latin America. The cultural popularity of the sport was growing exponentially and is well documented in China with the likes of Yao Ming and Jeremy Lin who are Asian sensations. With Latin American backgrounds integrating into the game of basketball, I wonder how these international translations are in turn changing the game we see at home. In Latin America, where the climate and geographies are so much different than the one in the United States, we find growth in basketball. Though the NBA in Latin America is growing, it is still not a hit in Central and South America. Though whenever you go either it is Latin America, China, America, etc… there is always someone playing the game. Even in the likes of Mexico, they are mostly known for militant based political revolution than anything else, but basketball courts do exist. The courts might be used for other things like farming during the day, but you will always see some kid playing and working on his game. Just like what I do when I am in my hometown hooping outside of my house, no court just the concrete and the hoop I have next to my garage. The growth of basketball throughout Latin America region is unexpected, only because they compete for national attention in their number one sport soccer. Basketball has to compete in Central American countries like El Salvador, Guatemala, Nicaragua, Cuba, and...

...Kobe Bryant is my favorite player in the NBA, and also my favorite athlete in all of sports. His career is getting close to being done, but he still continues to play at a superstar level. Kobe has played over forty five thousand minutes in his career, so it’s amazing how can continue to play at such a high level with all those miles on his body. He suffered his first major injury of his career a few weeks ago against the Golden State Warriors. He tore his Achilles tendon, and had surgery to repair it the next day. That injury forced Kobe to miss this seasons playoffs. He is expected to return in the next six to nine months. I don’t remember why or how I started to like Kobe Bryant, I just know I have been a fan of his ever since I can remember. Kobe Bryant was drafted sixteenth overall in 1996 by the Charlotte Hornets, and was then traded to the Los Angels Lakers on draft day. He won the slam dunk contest as a rookie. Just four years into his career. Kobe and Shaquille O’Neal teamed up to win three straight NBA championships. After losing in the NBA Finals in 2004, the Lakers traded Shaquille O’Neal and Kobe became the cornerstone for the Lakers. In 2006, Bryant scored a career-high 81 points against the Toronto Raptors, the second most points scored in a single game in NBA history. In 2008, Kobe won the NBA most valuable player award. After losing in the 2008 NBA Finals, Kobe led the Lakers to two consecutive championships in 2009 and 2010, earning the NBA Finals MVP Award...

...Nebraska: The terrorist would fly into Omaha, Nebraska and proceed to Silver Spur Ranches in Minatare, NE to begin his contamination. From there he would head to Krebs Ranch in Gordeon, NE and then Spade Ranch just south from there to complete his mission. The following graphic shows his respective route. Wyoming: The terrorist would fly into Denver, Colorado and proceed to Silver Spur Ranches in Encampment, WY to begin contamination. From there he would proceed north to Q Creek Ranch to finish the mission. The following graphic shows his respective route. Upon completion of the 3 days of contamination, the expected immediate effect would be approximately 1,000-3,000 cattle depending on the rate of transmission to other cattle. Those cattle infected in the first two days would already begin to show signs of the disease . The first week impact would likely spread to 20% of cattle on each of those ranches. The exact number of cattle on all ranches targeted is unknown but the number would be well over 2 million cattle. So, with 20% of cattle now infected by FMD in the first week the number of cattle infected has gone from 1,000 to 400,000. The disease would likely be noticed within the first week, but if the infected cattle were not separated quickly enough, the disease would continue to spread....

...Winning Time The Miami Heat and San Antonio Spurs have kicked off the NBA Finals in what appeared to be one of the greatest series ever. The Spurs were looking for revenge after last year’s heartbreaking defeat after being up 3-2 in the series. In game 6 of last year’s NBA Finals the Spurs looked to have it in control as Tony Parker hit a couple big shots for the Spurs with a two possession lead under a minute to play. But just when you thought the Heat were out and fans were exiting from American Airlines Arena, something special happened. LeBron James hit a huge three pointer to bring the Heat back within 2 and then Kowhai Leonard missed 1 out of 2 free throws to give the Spurs a 3 point lead with just under 20 seconds left to play. Running back on defense everybody in the world knows LeBron is taking this shot and going to try and tie the game to send it to overtime. LeBron misses; the rebound goes to Chris Bosh as he kicks it out to Ray Allen, with Mike Breen on the call as he would say “BANG, TIE GAME.” Ray Allen tied the game with 5 seconds left and from that point on everybody knew the Heat were going to win and tie up the series and eventually win in game 7. Miami would go on to be back to back champions of the NBA. This year however doesn’t seem to be that easy at all as the Spurs are up a commanding 3-1 lead with game 5 back in San Antonio on Sunday night. You could argue on which has been better, whether it’s been the Spurs offense or defense. In game 3 they set an incredible...

...THE WORD HERO JACK MOORE ENGLISH 122 MATT BOOKER APRIL 15, 2012 When someone mentions the word hero it doesn’t have the same meaning as it once did. The definition of a hero is one with heroic qualities in the opinion if others. To me or you, however a hero can be much more. Whether you believe an athlete should be a hero or deserves to be one. Most kids believe that they are. They buy their jerseys and put their posters on their bedroom walls. They watch them on TV or go to their games and look up to them like they are superhuman. Being able to dunk a basketball or throw a football down a football field may not seem heroic to the average person but to kid it is. To the average person they are just adults getting paid million to play a kid game. There are some exceptions to this there have been athletes who gave up their careers or postpone their careers to fight for this country. These are real sports heroes. Kids need heroes whether it is an athlete or someone else they provide kids with someone to look up to help them set goals for themselves. (Kareem Abdul-Jabbar 2013) “Heroes provide models of exemplary behavior to emulate. Heroes inspire kids to achieve more than they thought they were capable of, to find strength when they thought they didn't have any more, to follow a code of moral conduct when it would be easier and maybe more popular not to. But when it comes to sports figures, Americans seem a little confused about what defines the hero. While I, like...

...NBA Player Dress Code Right or Wrong? At the beginning of the 2004/05 season, the National Basketball Association (NBA) Commissioner David Stern enforced a dress code that requires players to wear particular attire prior to and after their games. This new rule has sparked plenty of controversy amongst the league, with experts, officials, and players all having their say on its intentions. Consequently, questions have been raised about the NBA’s management staff. Also, the link between the league and ‘hip-hop’ culture has brought about racial connotations. The code itself states that business casual is compulsory during all team or league business, including bus rides to the stadium, press conferences and also injured players who sit on the sidelines. The excluded items include sleeveless shirts, shorts, t-shirts, jerseys, sports apparel (unless appropriate for the event (e.g., a basketball clinic), team-identified, and approved by the team), headgear of any kind, chains, sunglasses (whilst indoors) and headphones (other than on the team bus). This means no more oversized baggy pants and coats with ‘bling’ covering their body. Although Stern claims otherwise, it is widely believed that the code was enforced in order to eliminate the hip-hop image the NBA has, making it a more fan-friendly league. The management was concerned on how the public viewed the NBA and their stars. Throughout press conferences before the code was enforced, the African-American players would be...

...No doubt about it, Kobe Bryant is one of the greatest of all time. He has accomplished so many things during his twenty-year career in the NBA. He is ranked third in the NBA all-time scoring list, just one ahead of Michael Jordan. Kobe has won five NBA championships with the Los Angeles Lakers and he is also the only player to play for the same team for twenty years. After reading, ¨Kobe¨ by Joe Layden, I learned a lot more about Kobe Bryant than I ever knew before. I personally like Kobe very much, but there are people out there who do not care for him. I can admit he is a ball hogger, one of the worst, but that doesn't describe him all around. Not everything about Kobe is the greatest, but then again no one is perfect. He was just a boy born in Philadelphia, PA with a big dream to play in the NBA. Right after graduating high school he was drafted by the Charlotte Hornets. People back then knew he was good, but they didn't know he was going to be one of the greatest of all time. Kobe Bryant's father was actually a former NBA player himself. When Kobe was only six years old he moved to Italy with his family so his dad could play in the Italian League. He was already becoming a good basketball player in his young years. In the book, it says, ¨He puts on his San Diego Clippers uniform-a miniature replica of one worn by his dad and frantically dribbles a tiny foam basketball around the room¨ (Layden 1). After reading this I could already tell he had loved basketball at a very young...
