Their structure and protective capacity are altered in high-energy impacts. Beside their energy-absorption capability, their volume and weight are also important issues, since higher volume and weight increase the injury risk for the user's head and neck. Anatomical helmets adapted to the inner head structure were invented by neurosurgeons at the end of the 20th century. Helmets used for different purposes have different designs. For example, a bicycle helmet must protect against blunt impact forces from the wearer's head striking the road. A helmet designed for rock climbing must protect against heavy impact, and against objects such as small rocks and climbing equipment falling from above. Practical concerns also dictate helmet design: a bicycling helmet should be aerodynamic in shape and well ventilated, while a rock climbing helmet must be lightweight and small so that it does not interfere with climbing. Some helmets have other protective elements attached to them, such as a face visors or goggles or a face cage, and ear plugs and other forms of protective headgear, and...

...Explain how risk factors can be minimised by utilisation of preventive measures Helmet: Contact sports usually involve wearing protective head gear, due to the high risk of head injuries and the potential damage such injuries can cause; these sports include rugby and American football, for example. Helmets are almost always worn when there is a risk of head injuries caused by high speed impact or accidents; examples of these sports include cycling, motor racing and bobsleighing. Helmets are also worn by batsmen in cricket to protect the head from the hard ball, which travels extremely fast when it has left the bowler’s hand as the helmet absorbs the shock of the ball and therefore minimises the effect on the batter. Shin pads: Shin pads are worn in many sports to support and protect the shins and ankles; wearing shin pads can help to prevent injuries such as fractures and sprains as well as reducing the likelihood of suffering from bruising and swelling. Shin pads are commonly worn in football, hockey and ice hockey. They minimise the risk of an injury as the plastic gets inbetween the other player and your shin while absorbing some of the shock. Gum shield: A gum shield is extremely important in many physical sports such as rugby and boxing as there is a high chance of the participant getting g hit in the jaw/head, the reason why the gum shield is extremely important when minimising the risk of injuries as gum shields reduce cuts to the lip, mouth and tongue, protect teeth...

Up came a half golden roman helmet, Stuart brushes the dirt of the helmet and the helmet was now shiny gold, it was decorate with signs, it really looks like signs from the roman time. Boat Mike and Stuart were speechless and they didn’t now what they have found. Mikes dad Stuart said the roman helm only was old clutter and he go bag to his business. To difference mike think the roman helm was so exiting. Because he just had Learn about the Roman time at his school so he knew exactly how such a helmet looked. He was sure that this half helmet was from that time. So he left his father in the garden and went inside to look at the half Roman helmet. He polishes the half helmet completely clean so you could see every detail on it. The helmet was really heavy so Mike had to put it on his desk while. When Mike had polished the helmet clean and nice, he showed it to Stuart. Stuart was convinced and believed that it was from the Roman time as Mike had said. Mike and Stuart took a picture of the helmet and sent it to a U.S. top research firms, the company had looked at the pictures and they called Stuart, the company told Stuart that it was an amazing discovery and it was long time ago they had experienced such a find before. Now they put the half Roman helmet to study at the research firm. And both...

...Will wearing a helmet minimise the effect of head injuries? We look at various examples and you’ll be shocked at our findings. Do more athletes have to die before changes are made? Methods of protection for head injuries in sport have been spoken about for years. Typically procrastination by bureaucrats within sporting and health organisations has meant no changes have been made. The question remains, however, does wearing a helmet in footy, soccer or rugby minimise the effect of a head injury? According to the Australian Football League (AFL) the answer is no. The AFL released a statement in 2012 saying… “There is some evidence that younger players who wear a helmet may change their playing style, and receive more head impacts as a result”. The same year National Rugby League (NRL) Chief Medical...

...History “Metal body armor fell into disuse in the 16th and 17th centuries, partly because armor that was effective against bullets was too heavy to be practical. Modern body armor reappeared on a small scale in World War I as a means of protecting the torso from shell fragments, but the armor, as designed, was too heavy to justify the protection that it afforded. World War II stimulated the development of lighter body armor that consisted of overlapping plates of steel, aluminum, or bonded fiberglass attached within a nylon garment that covered both the front and the back of the wearer. These “flak jackets” were flexible enough to permit relatively free movement by the wearer while affording him adequate protection against shell fragments. They could not stop an armor-piercing bullet, however. In the 1960s new types of vests were developed whose plates were made of composite layers of steel or a very hard ceramic, boron carbide. However, the discovery that numerous layers of nylon fabric could dissipate the energy of a bullet revolutionized the use of modern body armor. (Britannica, 2013) The function of steel or hard plastic armor is to be impervious to a bullet. By contrast, the textile vest deforms the bullet and then dissipates its energy, entangling it in the vest’s many layers. A textile bulletproof vest is fashioned of 16 to 24 layers of nylon cloth of a heavy weave, the layers stitched together like a quilt. Any ordinary pistol or submachine-gun bullet striking such a...

...Rhetorical Triangle Unit 1 IP Kevin Heer American InterContinental University The Rhetorical Triangle In getting to know the Rhetorical Triangle one must understand the three parts and how they are used in presentations. The following text uses two videos as examples of presentations and how the triangle fits within each one. For some time I have been searching for a new helmet that has many features for a great price. Motorcycle Superstore (MS) offer all lines of helmets at reasonable prices with videos and reviews that describe many of them. The speaker in this video was Mr. Harry McPherson, a sales representative for Nolan Helmets. Overall he did a great job in convincing me that he had knowledge of the product by presenting it with a strait foreword and informative presentation with little stutter or mistakes. He was wearing a professional looking shirt that gave off a knowledgeable sense of the product from the start. The vocabulary used in describing the product was top notch and very commanding. The situation in this case was describing the features, manufacturer and nature of a helmet that was in a room setting that gave focus on the product with no other items to take the attention away from it. The situation in this presentation included some close-ups that caught my attention. With myself being the audience, or any prospective buyer, had no trouble interpreting the message being conveyed by the speaker. Each element fit together very well and the video was successful...

...Helmets have undergone many changes through the years. In the early part of the 20th century, players wore leather helmets to protect their heads from significant trauma. Chin straps and leather pieces that covered the ears were added to the basic helmet form. Plastic helmets were manufactured in the 1940s and were used in the 1950s. Since the 1950s, padding has been added to the front, back and sides of the helmet to protect players' skulls from violent collisions and improving their chances of walking away from a clash with fewer injuries. Shoulder Pads Shoulder pads first started to be worn by players shortly after 1910. President Teddy Roosevelt had decried football as a violent game and said changes were going to have to be made to protect...

...Helmet Usage: Should It Be Required for Adults Gregory Boderck June 4th, 2011 Strayer University Abstract There is proof to present and statistical research to render that a motorcyclist wearing a helmet will not prevent head injuries or death in a serious crash. Using several studies provided by Charles Branas and Margaret Knudson, I will show that individual states with and without helmet laws show little difference in the effectiveness of a helmet in a crash. Many riders that I, myself have ridden with would rather have the choice of utilizing a helmet or not. Reasoning behind the abolishment of universal helmet law will be provided from a report filed by the National Transportation Safety Board, showing that helmets do not always protect adult riders in crashes. In some instances, helmets restrict a rider’s peripheral vision, as well as restrict their hearing depending on the style of the helmet used. Using a report written by Andreas Muller, PhD, I will stimulate the audience to believe that any type of helmet laws for adults will not reduce the number of deaths to motorcyclists. Helmet Usage: Should It Be Required for Adults Motorcycle helmet laws are not in effect in all of the fifty states. Over the last several decades motorcyclists’ deaths and severe injuries have increased significantly. There are many factors to account for the increase of injury and/or death to riders. Research has previously shown that a motorcyclists’ helmet will not protect an adult...

...Mandatory Need for Motorcycle Helmets The NHTSA (National Highway Traffic Safety Administration) estimates that helmets saved 1,784 motorcyclists from death in 2007. If all motorcyclists had worn helmets, an additional 800 lives could have been saved. As an avid motorcycle operator, I have been in a few close calls of my own. Luckily for me, if something would have occurred, I would have at least been safer due to my motorcycle helmet. It is safe to say that thousands of lives could be saved each year by national adoption of universal helmet laws. From 1984 through 1995, helmets saved the lives of more than 7,400 motorcyclists. However, more than 6,300 additional deaths could have been prevented if all riders had been wearing helmets (tntrafficsafety.org). There are minor debates about one not feeling comfortable while riding with a helmet because of to the weight of it. However, manufacturers make carbon fiber helmets that have virtually no weight. On average they weight around two to three pounds. They are a bit more expensive than your average helmet. However, one can’t put a price on life.But is it Safety should definitely be the underlying factor, especially since riding a motorcycle is already considered dangerous in itself. The analysis of fatal crash data from 2008 to 2010 showed 12 percent of motorcyclists in states with universal helmet laws were not wearing helmets, but 64 percent of riders...

...remove the motorcycle helmet law that had been in place for 20 plus years. This is been a hot topic that has had a lot of proposals, none of which seemed to be acceptable to Michigan lawmakers until the fate of Michigan motorcyclists was dangling in one man’s hand. Michigan Governor Rick Snyder made the difference when he voted yes to not enforcing motorcyclists to wear helmets. Since this decision there has been a substantial increase in fatalities of the motorcyclists. Michigan no longer requires motorcyclists to wear protective head gear. The new law basically states that if a rider chooses to not wear a helmet you are to have a $20,000 insurance policy that is supposed to cover your medical and other costs, in the event you are injured in an accident without a helmet on. It has been proven time and time again that $20, 000 will not cover even one day in a critical care unit at a local hospital. Michael Dabbs, president of the Brain Injury Association of Michigan, said the $20,000 insurance coverage that riders are required to buy “would probably buy a part of the day in the ER and intensive care and not much more”. (Durkin, 2013) Motorcyclists feel that if they are required to wear a helmet it takes away their personal freedom. They feel it is a breach of their freedom and motorcyclists stand firm on this belief. Bikers think that if they choose not to wear a helmet, bikers should not have to. Bikers back up their passion about not wearing a helmet by stating that people...

First, we can observe “the heaviest alcohol consumers are also the heaviest consumers of tobacco” or in another word "smokers drink and drinkers smoke." Second, we can recognize that” the association between alcohol and tobacco use, possible mechanisms of their combined health effects, and some implications for alcoholism treatment.” Third, some figures in researching show that “222 of 845 subjects had died over a 12-year period; one-third of these deaths were attributed to alcohol-related causes, and one-half were related to smoking “(1) Finally, alcohol and tobacco both have little positive aspects in social formality compared with their negative ones as proved above so that “society has attempted to minimize the consequences of using both alcohol and tobacco through public policy actions, including health warning labels, restrictions on advertising, and age restrictions on use”.(2) Hence, taxes on alcohol and tobacco should be increased to help pay for rising medical costs that is...

...Erick D. Norviel My Evil Knievel Stunt Unit 3, Assignment1 October, 11 2013 “Just because you think you can does not mean you should”. Those words spoken so many times by my Mom still echo in my mind. That summer day in 1978 in Cheyenne Wyoming was a hot day, blue skies overhead and the typical Wyoming wind was down to a soft breeze that helped cool us kids as we rode our bikes, played in the dirt and entertained ourselves using our creative ideas to come up with the next death defying stunt we would soon try to once again attempt to replicate our current hero, Evil Knievel. I was 11 that summer, finally playing with my older Brothers and their friends, accepted as one of them and this I felt, was my summer to prove to them that I was old enough and daring enough to attempt a stunt on my bicycle. That day the idea for our new stunt included a bike ramp and the neighbors Volkswagen Beetle car parked on the side of the road. So, began the planning, the construction, the design, all being done by the brightest and best carpenters and engineers from amongst the group of kids ranging in ages from 9 to 14. What could possibly go wrong? My clothing that day was pretty typical of most kids, cut off blue jean shorts and a t-shirt with basic tennis shoes. My bike was a picture of precision craftsmanship, created by my own hands from the many pieces and parts left over from my older brother’s previously wrecked, mutilated and destroyed bikes, not to...
