Xue Junqiang, secretary of the Bukseer County Party Committee, told reporters that there are more than 20 kinds of proven mineral resources in the county of Buxell, including more than 100 million tons of coal, bentonite, salt, oil, Glauberite, limestone, etc. .
It is understood that the deposit is located along the Baiyang River about 100 kilometers west of the county. In 2005, the China National Nuclear Industry Construction Corporation began to carry out surveys on its resources. Up to now, the metallogenic belt of plutonium has been identified approximately 6 kilometers. Experts predict that the long-range resources amount to more than 20,000 tons, and it is currently the largest volcanic giant thorium deposit in Asia.
Brake levers are usually mounted on the handlebars within easy reach of the rider's hands. They may be distinct from or integrated into the shifting mechanism. The brake lever transmits the force applied by the rider through either a mechanical or hydraulic mechanism.
Bicycles with drop handlebars may have more than one brake lever for each brake to facilitate braking from multiple hand positions. Levers that allow the rider to work the brakes from the tops of the bars, introduced in the '70s, are called extension levers, safety levers or, for their reputation for being unable to actuate the full range of travel of the main brake lever, suicide levers. Modern top-mounted brake levers, called interrupt brake levers, use an entirely different method of actuation and are considered safer.
The mechanical advantage of the brake lever must be matched to the brake it is connected to in order for the rider to have sufficient leverage and travel to actuate the brake. Using mismatched brakes and levers could result in too much mechanical advantage and hence not enough travel to properly actuate the brake (v-brakes with conventional levers) or too little mechanical advantage, requiring a very strong pull to apply the brakes hard (v-brake levers with other types of brake).
