...such as flying squirrels, gliding possums, and colugos, can only glide for short distances. Bats do not flap their entire forelimbs, as birds do, but instead flap their spread-out digits,[4] which are very long and covered with a thin membrane or patagium. Bats are the second largest group of mammals, representing about 20% of all classified mammal species worldwide, with about 1,240 bat species divided into two suborders: the less specialized and largely fruit-eating megabats, or flying foxes, and the highly specialized and echolocating microbats.[5] About 70% of bat species are insectivores. Most of the rest are frugivores, or fruit eaters. A few species, such as the fish-eating bat, feed from animals other than insects, with the vampire bats being hematophagous, or feeding on blood. Bats are present throughout most of the world, performing vital ecological roles of pollinating flowers and dispersing fruit seeds. Many tropical plant species depend entirely on bats for the distribution of their seeds. Bats are important, as they consume insect pests, reducing the need for pesticides. The smallest bat is the Kitti's hog-nosed bat, measuring 29–34 mm (1.14–1.34 in) in length, 15 cm (5.91 in) across the wings and 2–2.6 g (0.07–0.09 oz) in mass.[6][7] It is also arguably the smallest extant species of mammal, with the Etruscan shrew being the other contender.[8] The largest species of bat are a few species of Pteropus and the giant golden-crowned flying fox with a weight up to...

We have organized it by: the complaints, responses, and sources to where we have found our information. Arguments in the letter | Potential responses | Research backing the responses | How could you risk my son's life by not changing the standards for bats immediately when your tests showed that a player cannot react quickly enough to avoid a ball batted by one of these high tech bats? The NCAA should be ashamed. I am writing my congressman. | The NCAA has already attempted to change the standards a year ago, but ultimately the company would be sued by one of our top manufacturers (Easton), which directed the company to limit the performance of all composite bats. Also, the miles per hour from an average hit off of a composite bat are 93.3mph whereas for a wooden bat, the power of the bat generates an average of 86.1mph. Although this statistic was provided by Brown University and was set forth over a decade ago, the standards have been drastically been shaped to allow for much safer composite bats than in previous years. | | What are the results of your research in the area of bat technology?I saw a show on Fox Sports Net in the Spring that made some claims that not only are batted balls faster than ever, that the 1999 rules for bats would not change that fact because the bat makers were going to add the weight you require to the bat handles...

...Wood bats are safer for high school and college; however metal bats have better performance. With the ball speed off of the bat as the big safety issue for high school and college, wood bats have a slower speed than metal bats do. With every solution there is a problem to the solution; wood bats do not produce like metal bats do. The game play is different with each bat. The changes that the National Federation of State High School Associations (NFHS) and the NCAA make for bats for play will have an effect for upcoming students. In High school and college the players get to use metal bats instead of wood. The performance of metal bats is a lot higher than wood. That is why college and high school use metal instead of wood bats. Metal bats have a higher ball speed off the bat, which is the safety issue that the NCAA and the NFHS have right now. There is a new standard for baseball bats which took effect in 2011 which is the Batted Ball Coefficient of Restitution (BBCOR) bats. They have almost the same ball speed off of the bat as a wood bat does, but the metal bat has a bigger sweet spot. A sweet spot is the part of the bat that will give the biggest trampoline effect to the baseball. Metal bats have made scoring runs in high school and college a lot easier than wood bats. The BBCOR bats have had a slight decline in runs and hits unlike the Ball Exit Speed Ratio (BESR) bats. The change from BESR bats to BBCOR happened in 2011. BESR bats had to high of a ball exit speed off of...

With all of the letters being sorted into 5 different categories, I was able to write an adequate response for each of those 5 categories to send out in a bulk method. Why has the NCAA not banned the use of metal bats? : * First and foremost make sure to apologize for their unfortunate experience and assure them that changes have been made to protect the safety of the players involved. * Explain in detail the efforts made by the BBCOR to ensure the approval of only certain bats that meet its requirements. * Ensure the writer that each and every bat that is available for use in the league that it will be stamped with a NCAA certification mark. * http://www.ncaa.org/sites/default/files/BBCOR%20Protocol-Effective%201.1.14.pdf Outside research and lack of change/action taken by the NCAA to change regulations: * Start out by acknowledging their effort to write a letter to us and tell them that we are always looking for ways to better the safety efforts and standards for the players. * The writer’s information may be outdated, because the BBCOR regulations of 2014 have made a significant change in the “trampoline effect” and are much safer than they were in prior years. * Each and every bat must be approved and the facts can be checked at our website...

...Project is to determine which type of baseball bat is best. Aluminum or wood? In my personal opinion aluminum is best because they are lighter and easier to swing. Aluminum bats are lighter therefore you can swing it faster than a wood bat. It also has a wider sweet spot so the ball come off the bat faster. An aluminum bat may or may not hit further – depending on the batter, but the batter will have more control of the bat because it is lighter. Wooden bats are heavier so they have less recoil. A wooden bat moving at the same speed of an aluminum bat will hit harder. If the batter can get the bat moving fast the ball will go further, that’s if he makes contact. Wooden bats also do not vibrate as much which is better for the batters hands. When the NCAA approved the use of aluminum bats in 1974 they started to compare statistics. They found that the team batting averages went up about twenty points, and home runs doubled. The main reason wooden bats are required in the pros is because of this performance difference. “Pro leagues want to protect their historical records, and they want the performance of the game to be the result of human ability, rather than the technology of the bats,” says George Manning. The bottom line is that non-wood bats do lead to higher batted ball speeds and this means harder line drives and deeper fly balls. They are much easier to swing and because it is lighter you have better control of the bat. It is easier to make “last minute adjustments”...

...companionship. Although Peter is gone, the memory of his good and loving soul is captured in this worn out mitt. Peter’s glove is a left-handed fielder’s mitt. The glove isn’t in very good shape. The smooth and firm leather of the mitt is now quite ragged. The stitching of the mitt is loose and is in desperate need for repair. Dirt and dust from numerous baseball fields have taken its toll and damaged the sturdy webbing of the mitt. What used to be a well-inscribed white logo of a company has disappeared, with the exception of the lonely remains of a letter “d”, now standing all alone. The most outstanding part of the mitt are the numerous poems written on it. My brother copied the poems, so he had something to read, when no one was up at bat. The bright green ink, what used to be like the first green leaves on a warm spring day, is now faded, but still readable. One poem that stands out is written on the backside of the glove, where time hasn’t caused a lot of damage. The leather, on which the poem is written on, is in excellent condition, when comparing it with the rest of the glove. Both the author and the title of the poem remain unknown to me and I’d like if it stayed like that. Sometimes I even dream, that Peter wrote it himself, just for me to...

...not exist at all, but rather that it does not exist in the way that Major League Baseball defines it. The rulebook definition is a rectangular solid hanging in space, with infinitesimally thin boundaries which, once touched, trigger strike calls. The actual strike zone is a shifting, nebulous cloud of probability density. It moves up and down with the whims of the umpire and the policy changes of MLB. It shrinks and expands as the count becomes favorable or unfavorable. It grows when an experienced pitcher throws and contracts when bad pitch framers snatch pitches with exaggerated body movements. It’s not a static thing, fixed for every hitter of every height; instead, it is constantly dynamic, flowing with the previous pitches and at-bats in a game. I render here no judgment as to whether the strike zone ought to be this way. I’m only noting that according to all available evidence, it is this way. As a first pass approximation, it’s okay to think of the zone as that imaginary rectangular solid, i.e. in its unicorn form. But with the greater granularity afforded us by PITCHf/x data, we...

...Dhampir Dhampir are an extremely rare breed created by two methods. One is for a First Generation vampire to mate with a human. The second method is if a vampire goes through the process of turning a human into one of their living dead kind. There is a small window of vulnerability where powerful magical or religious forces can intervene. Generally success equals a Dhampir. These Dhampir’s often go on to be Vampire Hunter since their human half tends to amazingly mentally dominate their mental state while their physicality is powered up by the demonic vampire side. Dhampirs have increased strength, speed, agility, and somewhat limited vampire hypnosis skills. They are perfect for vampire hunting not only thanks to their increased physical abilities but the fact that they can sense, and track vampires rather easily. This includes smelling vampire blood from great distances. This is why even their vampire parents will try to eradicate them. They can’t risk the danger, and dishonor of being slayed by their own offspring. Naturally their is great dishonor among vampires if one of their kind, or even a halfling, goes around killing them. It’s a stain upon the vampire parent which can lead to their termination by the order of vampire royalty. The Dhampir urge for blood is minimal, and is easily satisfied by a moderate amount of animal blood. They simply don’t crave human blood, and therefore are not a threat to humanity. They eat a mostly carnivorous diet that is heavily...

...Zhiwei Duan ChampSport Report ChampSport is a company which focus on the sporting goods, particularly in the various racket sport arenas. A new idea of replacing metal baseball bats by the use of the alloy was under considering. After I calculated the beta, NPV, and NPV sensitive analysis, I high recommend that we should accept this project. For the Beta calculation, I collect the industry data and average them to get the average asset data, which I think is more reasonable to explain the level of the risk for the ChampSport INC. Then I conduct the equity beta for ChampSport is 1.01. Finally, I got the 7.43% as the result of the WACC. (See Comparable Firm sheet) After that, I do the NPV analysis. When calculating the Operating Cash Flow, I decide to omit the expense of the research and development cost since it is the sunk cost and will not affect the future project and profit. I also assume that the annual increase rate for price of the product is 2% and annual growth rate of sales is 10%. By doing that, I generate the operating cash flow and finally get the NPV $11,227,508 and IRR 18.54%. Based on our assumption, the NPV shows that really bright future and profit ability for this project. Finally, I also did the NPV sensitive analysis to see how much the effect of WACC, annual growth rate of price and sales to the NPV. We can see that with the growth of the WACC to 12%, the NPV decreases to $5,355,268 and still keeps high positive. For the table of the NPV sensitive...

...The Virginia Big Eared Bat (corynorthinus townsendii virginianus) The Purpose of this recovery plan is to restore self-sustaining populations of Virginia’s Big Ear Bat. The taxonomy of this species is that it is in the class Mammalia, order chiroptera family vespertilionidae, genus corynorthinus, species corynorthinus townsendii, subspecies corynorthinus townsendii virginianus. (ITIS, 2015) The Virginia Big Eared Bat is a mid-sized bat that weighs around seven to twelve grams. Its body is 9.8 cm long and the ears that it is named after are 2.5 cm long. It has distinctive facial glands on both sides of its nose. The fur on both the ventral and dorsal sides of the bat is mono-colored and brown. (Kunz and Martin, 1982; Reynolds and Fernald, 2015) The US distribution of the Virginia Big Eared Bat is in areas of East-Central Kentucky, parts of West Virginia, northern portions of North Carolina, and in the westernmost parts of Virginia in the James and Potomac River tributary valleys. (Sullivan, 2009) The distribution within Virginia is in six eastern counties. At this moment it is known to take residence within three caves in Tazewell County during the summer, and five caves spread through the Highland, Bland and Tazewell counties during the winter. It is only one of two Virginia bat species which roost in caves in the summer. Also it is not that they live in just any cave they only live within limestone caves. There are also only three known maternity colonies. (Virginia Department...
