Playing any kind of sports cannot only be a great way to get in shape, it can also improve your overall health and provide a healthy outlet for your emotions. Whether you're an active member of any sports team or you just like to jog around the block every morning, believe it or not, you're also increasing your chances of acquiring certain skin conditions.
A fairly common acne condition you might get when playing any kind of sports is Acne mechanica. This condition is triggered by the humid environment usually present in gyms and locker rooms, excess sweat, friction, and heat caused by tight athletic gears or outfits.
If you're not sure what causes the acne on your back or shoulders, it might be the sports gear you use. Take note of these following situations that usually lead to acne mechanica:
- You regularly wear protective gears such as caps or helmets and you notice zits growing on the area covered by your helmet.
- The area covered by your knee pads starts to develop zits and acne-like rashes.
- The strap of your backpack seems to irritate your shoulders because zits start to sprout even though you never had acne on that area before.
- The breakouts on your legs seem to worsen every time you wear your favorite skinny jeans.
- Areas covered by your tight brassiere start to develop rashes and pimples.
In some cases, this condition can be triggered if you have “sandpaper acne” prior to using tight sports outfits or gears. Despite the possibility of getting acne mechanica, however, you shouldn't be discouraged to try out for your college soccer team since there are many ways to prevent and treat this condition:
- Always wash your sports outfits and use only clean shirts made of breathable fabrics.
- Try to avoid wearing man-made fabrics such as polyester since these kinds of cloths do not absorb excess sweat.
- If your sports gear is too tight, try to loosen it up a bit or wear a breathable fabric underneath to protect your skin.
- If you really don't need to wear a headband or a hat, then don't wear it at all. Prolonged use of tight headbands and caps can trap in the excess oils and might provide a excessively humid environment for the pimple-causing bacteria to grow.
- Clean your sports gears on a regular basis to prevent build-up of bacteria and excess sweat.
- Do not rigorously scrub any area that might be affected by this skin condition since friction might cause more breakouts.
- After cooling down, try to take a shower immediately to remove excess oils and relieve your skin of the friction and heat that might be caused by your uniform.
- Try applying medications on the affected area. OTC treatments such as benzoyl peroxide, resorcinol, and salicylic acid can help remove those acne-like rashes.
If your acne mechanica doesn't improve after trying out these tips, you can try to consult a dermatologist for a more effective treatment.
The Oldest Computer Of The World!
Thanks to the sophisticated techniques of radiography and imagery, an international team of researchers comes to elucidate the operation of one of the most mysterious objects of ancient Greece. Discovered in 1901 in a Roman wreck, it would be about a very sophisticated mechanical computer dedicated to the study of the astronomical phenomena. Of frightening complexity, it counted at least 37 bronze gears gone up in a box out of wooden of 31x19x10 cm. On the back face, two large dials in spiral indicated the phases of the Moon and made it possible to predict the eclipses.
On the front face, a dial posted the position of Sun and the Moon compared to the stars. The mention of the Venus planet leaves think that other indicators, now disappeared, reproduced on this same dial the trajectory of five planets known at the time.
Fortunately for the researchers, the originators of the mechanism described the operation of certain components on its case! Indeed, its refinement is such as a pair of offset gears simulated the modification the apparent speed of the Moon caused by the eccentricity of its orbit! Moreover, one device quite as clever introduced a correction for the leap years.
The Greek astronomer Hipparque or one of his disciples probably took part in his manufacture between 150 and 100 before our era. It would be necessary to wait more than a thousand years before finding comparable machines. Who knows which other technological wonders of Antiquity disappeared without a trace?
The technology was originally developed not for archeology, but as a method for improving photo realism and rendering efficiency in 3D graphics. It also could be used in criminal forensics, detecting distinctive characteristics in footprints or tire marks, for example. The technology also still has potential commercial uses for HP, but many of the techniques have been made available to the scientific world for academic purposes.

Toyota Lexus GS300: Venerable Luxury with Durable Toyota Parts
High equipment levels and meticulous quality and refinement have been the formula for building and maintaining the Lexus. It embodies a fresh design approach, re-engineered from the ground up.
Dominated by a long cabin with steeply angled front and rear glass, the windows allow plenty of light into the well-organized interior. The Rear passengers get plenty of legroom – the wheelbase has been lengthened by 50mm – and large quarter-windows.
The GS300 Sports at $95,000 includes climate control, heated and ventilated front seats, auto headlights and wipers, reversing camera and steering wheel audio controls. The Sports Luxury model tested here adds satellite navigation, a sunroof, intelligent cruise control, parking sensors and an excellent Mark Levinson stereo system.
Operating full time, the GS300's all-wheel-drive system features a planetary gearset and a wet, multidisc clutch to couple the primary drive wheels, at the rear, to the front. The standard torque split is 30/70 front to rear, but the system's electronic brain can vary that to 50/50, making its judgments based on various driver inputs such as throttle angle and steering angle, and vehicle data such as wheel speed and yaw rate
Every GS has three variations of a new close-ratio six-speed automatic transmission, each designed for optimum performance with their respective GS applications. One of the smallest and lightest gearboxes of its type, it includes a sequential manual shift mode, with gear changes made via a lever in the center console. An outstanding feature of the car is the all-wheel-drive system. The more slippery the road, the more pronounced is its advantage over conventional two-wheel-drive systems.
The car has an all-new 3.0-liter DOHC 24-valve aluminum V-6, which replaces an iron-block straight six of identical displacement. With Toyota's VVT-i variable-valve-timing system operating on cams, plus direct injection, plus a formidable 11.5:1 compression ratio, the new six generates 245 horsepower and 230 pound-feet of torque, compared with 220 of each for its predecessor. The new V-6 is bolted to an equally new six-speed automatic transmission, featuring manumatic shifting and an electronic brain that does a good job of avoiding excessive hunting, particularly in uphill runs.
Other features include leather-trimmed, heated front seats with 10-way power adjustment; SmartAccess keyless entry and a pushbutton starter; a premium sound system with both CD and DVD capability; Bluetooth wireless telephone technology; and a 7-inch multi-information touch screen for easy access to a wide range of information and commands.
Options include: a steering-sensitive Park Assist system; DVD navigation system and rear backup camera; one-touch open/close moon roof; ventilated front seats; power rear sunshade. It also has an eardrum-pounding, wallet-smashing Mark Levinson audio system, its 11 channels of sonic wash flowing through 14 speakers, Rain-Sensing Wiper package that includes adaptive front lighting and headlamp washers (standard on the GS 430); a rear spoiler; and all-season run-flat tires. Luxurious amenities, exquisite quality, and remarkable technology—these are all the things that make up a Lexus. Partstrain likewise strives to preserve these qualities in delivering only the best Toyota Replacement Parts, Performance Parts, OEM and Aftermarket Parts.
As many customers are satisfied with Toyota cars, Parts Train has been the top choice of millions of Toyota owners for many years. Its diverse line of excellent Toyota replacement car parts, auto body parts, Toyota interior parts and Toyota exterior parts, Toyota motor parts and more can be found at its online store.

Used Cars - Second Hand Cars - Tips For Buying
Don't buy a car in the rain, the bodywork always looks better when it's wet, plus, the chances are you will forget to check something by rushing to get out of the rain.
Stand at the front, or the back of the car, and look along the body line. You will be able to see if it has had any body damage as the light reflecting off the side of the car will show the dents or replaced panels.
Check around the window rubbers for over spray, a sure fire way to see if a car as been touched up.
Check the gaps between the panels to make sure they are even on both sides of the car. Bonnet to wing etc. This is a good indication as to whether the car has been in an accident and had panels replaced.
Take a fridge magnet with you and check the bodywork for filler. The magnet will stick to the metal, but will fall off if it meets body filler.
Have a look at the interior of the car, does the wear inside the car look in keeping with the mileage. If the car looks like its done 100,000 and the clock says 25,000. Then you know its been round the clock, or even worse clocked. Check the steering wheel, and accelerator pedal rubber for excessive wear, the clutch and brake pedal rubbers can be replaced, but the accelerator pedal is a lot harder to change, and will give a truer indication of mileage.
Check underneath the car for any oil or water leaks, also check the floor where the car has been standing for the same.
Check the tires for uneven wear, if the tires are worn more on one side than the other its an indication that the car may have been in an accident and the chassis is twisted. It could also be the tracking or wheel balancing. Either way its not a good sign.
Drive the car, (with the radio off) and check for any knocks or strange noises. Check the steering for vibration, or pulling to one side, its an indication again that the car may have been in an accident and the chassis is twisted. Make sure you drive the car in all gears to check the gearbox.
Try a 3 point turn in the car, that will check the reverse gear, and if you put the steering on full lock you will be able to check the wheel bearings and steering rack (your looking for clunking sounds or creaking).
When the engine is now hot check the oil, if it is milky there is water getting in somewhere, which could indicate a head gasket. (very Costly). The oil should be filled to between the 2 marks on the dipstick. If the oil is brand new beware, not many people will change the oil on a car the day before they sell it unless they are trying to hide something. Also check the water reservoir for signs of oil, not a good sign.
Last of all, check the paperwork. Make sure the registration document is in the sellers name. They may be a trader trying to pose as a private seller. Check the MOT to make sure its current. Check the service history to make sure it matches the vehicle being sold. Also you may want to check the engine and chassis number to see if it matches what is on the registration document. You will find that information on a small metal plate located under the bonnet. If the plate is missing be suspicious.
It's also a good idea to get the car HPI checked. This will tell you if the car has been stolen, been in an and accident, or is on finance. It costs around £40 but well worth it.
If you follow these rules when buying a used car you wont go far wrong. If you can't be bothered to go through the hassle, then buy your car from a trader, he or she will have already done all these checks to cover himself before he or she purchases the car. I would not buy a car without doing these checks first.

Big RC Cars Are Big on Fun and Excitement
There are some really big RC cars on the market these days and they add to the excitement of racing as their sheer size helps then race over rougher conditions than the smaller cars. With huge knobbly tires and long travel suspension these big RC cars can be raced through mud, over sand and through long grass. With the long suspension travel and big diameter soft tires they can also jump over big humps without doing any damage and can land from great heights and continue racing. Many of these big RC cars are over one and a half feet long and are wider enough to corner at high speeds without tipping over. To get these Big RC cars to perform they need powerful engines and that is exactly what they are powered with as the new generation of engines produce more power than ever. Some of these big cars are even powered by two engines for enormous power and most of the cars are four-wheel drive for added traction.
There are also a number of really aggressive RC trucks that look enormous compared to the vehicles that were offered just a few years ago. The big RC cars have a very wide track and the mechanicals are set low in the chassis for a lower center of gravity. This lower center of gravity helps with the stability of the vehicle particularly when cornering. The big soft tires give so much traction that the gears in the differentials and gearboxes have had to be upgraded to handle the power from the twin engines. Lighter gears can be prone to damage when there is too much traction and too much power applied on surfaces such as grass where the wheels won’t spin. Fortunately there are many parts that can be replaced relatively easily and at little expense.

Reverse Gears: Functions and the Evolution of New Technology
Gears are an integral component of most mechanical devices that are in use today. Gears have wide ranging functions, but they are used for transmitting motion between two shafts. Moreover, they provide torque to a device that a fast spinning small motor cannot provide. Another important feature of gears is that they give direction to the process of rotation. This article provides information about just these types of gears, specifically reverse gears.
A pair of gears, one present on the counter shaft and the other on the output shaft are used to implement the process of ‘reverse’. As opposed to forward gears that are meshed together, there is some amount of space between the reverse gears. Another point of differentiation from forward gears is that reverse gears are joined to their shafts. There is no free rotation around the shaft. There might develop a scenario when a small gear that is known as the reverse idler is slid between the two gears. The function of this gear also called the idler gear is to mesh the two gears together. This enables it to change the direction of the rotation, but it does not hamper the gear ration in any way.
The method of working of reverse gears is not as complex as it seems. When the reverse gear is selected, the gear teeth of these gears are meshed. There is absolutely no aid from the mechanism that seeks to synchronize these gears. This is one of the primary reasons why the output shaft must now move, once a reverse is selected. That mean a car must be stopped when you want to select the reverse gear. Many automobiles have a mechanism wherein the input shaft also stops spinning when reverse gears are selected. This decreases the grinding that accompanies the selection of reverse when there is an inertial spinning of the input shaft.
Car companies do not necessarily uses the same reverse technologies across all makes. Advanced technologies make possible the use of sophisticated reverse gears in modern cars. Of course, these cars come with a hefty price tag. But, more often than not a mechanism is used which stop the transmission of the input shaft. If this is not done the vehicle produces a whining sound. This is why all car manufacturers use the idler that, as aforementioned, can be inserted between the two gears. This procedure reduces the accompanying noise to a great extent and in the service manual of many companies; you can find a mention of this system as a “noise reduction system”.
A new kind of reverse technology has entered the market in the recent times, called ‘spur reverse technology’. This technology has made a few improvements to the one that have been listed above. But, it has compromised on a few aspects like, robustness, engagements, and noise. But it has found acceptability because there is limited driving that takes place in reverse.
