(Extreme sports) An Introduction to Sprint Carting
No commentsBy Daron Soto
Imagine - ripping your torso as you hit a curve launching your sprint kart down the circuit. Pressing on the accelerator as you exercise dead-on hand-and-eye coordination determining the smartest way to turn the drift in the 21st minute of an hour-long enduro race. Or perhaps be a spectator - routing for the likes of Fernando Alonso and Michael Schumacher as they race neck-and-neck on the last lap. Guess what - you are breathing and witnessing (even smelling the distinctive aroma of clay dirt on the dirt track) the atmosphere that comes with go-kart racing.
Developed in the 1950s by pilots with a zest for tinkering with motorcycle engines to propel simple frames, go-karting extended internationally after the construction of the first go-kart by Art Ingels in Pasadena. Before dwelling on it’s mass European appeal and discussing the pinnacle of Formula 1 racing, let’s backtrack for a second. Riding go-karts (or karting) is the best way to break into professional racing. It is the simplest means of exploding your chassis down the track before getting into the sophisticated arena of professional racing. Single cylinder engines, basic chassis models, and lack of speed producing components provide go-kart racing with the air of simplicity, geared towards beginners and novices.
The concept of sprint karting comes to our mind when we think of the prototypical kart & track in amusement parks, recreational areas, and arcade palaces. Impeccable karts with sleek designs and sturdy frames rip through on short tracks, usually made from asphalt or concrete - ranging from half a mile to a mile in length. Sprint karting is divided into classes (think boxing middleweights and welterweights) that distinguish engine-types (two-and four-cycle), driver (classified according to age and weight), brand of kart (Yamaha and Honda are popular choices), and specifications. No carbon-fiber made frames and McLarens built with lightweight materials here! Sprint karting is a simplified, scaled-down form of professional go-kart racing with shorter tracks, downgraded technology, less experienced drivers, and downgraded components across the board.
Other forms of karting include enduro racing. Endurance racing, or “enduro” for short is a prolonged version of sprint. Propelled by aerodynamical butterfly steering, enduro karts are an upgrade over sprint karts - participating in races lasting an hour or more. Dirt, oval tracks is the staple of endurance racing and is more prevalent in the Midwest than anywhere else. Because of the long racing period, special emphasis is paid to durable karts and pit stop maintenance than focusing on just speed. In runner’s terms, enduro is a marathon - not a sprint. If you sacrifice chassis and tire maintenance for speed throughout the course of a race, reaching the finish line is out of the question.
Behind every successful sprint car are its well-performing components, specifically its frame, engine, and tires. The dynamics of a go-kart is two-fold: to be built to withstand the rigors of racing and to serve as the backbone for speed. Usually made of steel, frames have the option of being flexible or not. Flexible frames mean easier maneuvering along the track, especially when turning as to maintain good “side bite” and control of the kart. Because non-professional go-karts have no sophisticated traction and suspension system to withstand bumps, frames are usually subject to more punishment. Sprint kart tires usually do not have indented grooves, as they are soft in nature and more suited to all-terrain.
900 BHP horsepower engines are the norm for souped-up Honda Formula One karts. Capable of reaching speeds of 200+ mph, they represent the all-out nature of karting technology. For the novices, a simple 2-cycle engine will do! Running on gasoline and electricity instead of petrol (typically mixed with other fuels to suit environmental conditions for Formula One,) sprint karts run on either 2-cycle or 4-cycle engines. 4-cycle engines are the weakest engine around, with horsepower topping 20 HP. Think of the power needed to run a heavy-duty vacuum cleaner - that’s how much power a 4-cycle engine exerts. 2-cycle engines are typically associated with the likes of Vespas (European motor scooters) and mopeds. These go up to 90 HP. Added cylinders (individual horsepower generators in go-karts) can boost horsepower, adding pure speed & power to your machine. Perhaps 10-cylinder Formula One kart engines and its incredible capabilities ring bells to you now!
Want pinpoint control over the speed of your go-kart? No problem here! Go-karts have basic transmission systems with gears that control speed to its desired amount. Coming with clutches, shifter karts (a popular type of sprint kart that allows you to move at a certain amount of speeds) make the best use of engine power when zipping along a straight path or maneuvering over the short or wide curve. Depending on the amount of cylinders and engine, shifter enthusiasts can lay opponents in their dust blazing trails up to 90 mph. Shifters usually run on larger road courses known as road racing. It is flush in structure with qualification criteria like class of kart, weight of driver, etc. Honda, Kawasaki, and Yamaha are popular suppliers of engines. These companies are at the forefront of karting technology, regularly tinkering with what’s already available or creating new concepts of their own.
Sprint karting opportunities are available to everyone. If you want to enjoy it as a form of recreation instead of competition, visit your local track and rent a kart! Make sure to sign any insurance waivers and become acquainted with the rules and regulations! If you like to compete, inquire from within. Sprint karting is one of the least expensive sports out there. People from all walks of life and all economic backgrounds can drive a kart, or even purchase their own with a powerful engine. There are many karting schools available all over the nation that will let you ride their karts for a nominal fee. In essence, karting is more than a pastime. It is a bonafide sport capable of preparing you for more advanced karting by helping you shape your judgment, hand-eye coordination abilities, and technological/dynamical know-how of the instruments you’re using.

United States Passports

United States Sets Date for E-Passports
The U.S. State Division says all U.S. passports issued starting in October 2006 will contain RFID chips.
The U.S. Express Division issued its final rules today specifying its plans to concern electronic passports (e-passports) containing RFID tags. The division says it intends to begin its e-passport program in December. The first stage will be a pilot program in which e-passports will be issued to government employees utilizing official or diplomatic passports for government travel. This pilot, the division says, will permit field-testing prior towards the very first issuance towards the American traveling public, early next year. By October 2006, all U.S. passports, using the exception of a small number of emergency passports issued by U.S. embassies or consulates, will include RFID tags.
The final rule incorporates amendments resulting from comments to a proposed rule originally published in the Federal Register on Feb. 18. The State Department says it received a total of 2,335 comments concerning its proposal to introduce e-passports. The division categorized 98.5 percent from the feedback as negative, 1 percent as positive and 0.5 percent as neutral. Concerning issues raised by those comments, the department says 2,019 expressed security and/or privacy concerns; 171 raised basic objections to the use of the information chip and/or RFID; 85 expressed basic objections towards the use of electronic passports; 52 listed basic technology concerns; and 8 focused on religious problems. The feedback are obtainable for review at the travel.express.gov section from the department’s Web site.
The chip used in the e-passports will comply with the ISO 14443 RFID specification and contain the same information as a passport’s information page?the passport holder’s name, nationality, gender, date of birth, place of birth and digitized photo. The chip will also include the passport amount, concern date, expiration date and type of passport. The ISO 14443 specification permits chips to be study when an e-passport is placed within approximately 10 centimeters of an RFID interrogator (reader).
Of all objections the department received regarding its plans, the overwhelming majority expressed concern over the possible for skimming and/or eavesdropping. Skimming may be the act of creating an unauthorized connection with an RFID tag so that you can gain access to its data. Eavesdropping may be the interception from the electronic communication session between an RFID tag and an authorized reader.
To prevent skimming, the division will add shielding material to the passport’s front cover and spine. The material is supposed to make the e-passport’s RFID tag unreadable as long as its cover is closed or nearly closed. The department will also implement Basic Access Control (BAC), which functions as a Personal Identification Number (PIN) in the form of characters printed on the passport information page. Prior to a passport’s tag can be study, this PIN should be inputted into an RFID reader. The BAC also enables the encryption of any communication between the chip and interrogator.
To ensure that U.S. e-passports are interoperable with other nations’ systems, the document’s embedded RFID chip will comply with specifications developed by the International Civil Aviation Organization (ICAO). The ICAO specification requires a minimum capacity of 32 kilobytes of memory for storing data on the chip, whereas the U.S. government has opted for a chip with 64 kilobytes of memory to allow for the potential storage of extra data or biometric indicators such as fingerprints or iris scans, sometime within the future. Before the division adds additional information or biometric identifier other than a digitized photograph, however, it says it will seek public comment through a new rule-making process.
A number of other nations have already begun issuing e-passports, including Sweden.

Choosing The Right Sports Fencing To Suit Your Sport
By Xander Palmer
Different sporting activities require different perimeter sports fencing and choosing the right one to suit your needs is important. Times have changed and there have been vast improvements in sports fencing in recent years. Gone are the days of noisy wooden kick-boards that needed replacing and repairing every year.
Some fencing companies specialise in sports fencing. They manufacture and supply a wide range that can be tailored for almost any sporting activity. Whatever the sport, there are fences that will be able to perfectly suit your needs. There’s sports fencing called Super Sports Rebound which is ideal for high impact sports such as five-a-side football. It features a twin wire construction that is designed to replicate the bounce you would get from wooden rebound boards but without the wear and tear associated with these. As well as the wear and tear issue it also features synthetic rubber inserts which reduces ball impact noise and makes it ideal for residential areas.
There is also sports fencing custom made for hockey pitches which can be used in place of wooden rebound boards and features progressively narrower gaps from top to bottom which ensure maximum hockey ball retention. There is sports fencing custom made for tennis courts which features smaller gaps in the mesh to ensure that tennis balls cannot escape whilst also being unobtrusive enough to allow easy viewing through it from spectators.
There are several types of sports fencing that can be installed with built in goals or basketball units and also cranked fencing tops which increase ball retention. Additional cranked panels can also be added to the top of the fencing to prevent sports balls escaping even further. For complete ball retention there is a Sports Barn fencing system which incorporates a roof, making lost balls a thing of the past and also allowing all weather sports activities.
Whatever your sport, you should be able to find the sports fencing to suit your needs. Some companies also offer free site surveys where an expert will come to your premises and advise you on prices and quantities so that you don’t over-order.
