One of the many prerequisites to obtaining a permit to mine a certain area is that the company must outline how it plans to leave the land once mining is complete. These plans usually fall under one of two categories: restoration or some form of use for economic or community development. In West Virginia and across Appalachia, any type of major development requires the natural landscape be altered. The mountainous terrain provides little land naturally suited to development. The natural landscape of West Virginia can be characterized usually as a narrow valley floor between 100 and 1,000 feet wide surrounded by steep mountainsides that are often a 50- degree slope or more. What this means is that any development is naturally limited by the landscape. Overcoming this limiting factor is ...

KIRKUK, Iraq - If civil war were to resume in Iraq, a dread event that could mean the breakup of the world's next great oil power, the city of Kirkuk is the likely epicenter.
It doesn't take much to set ethnic tensions boiling in this oil- rich province of 850,000, also named Kirkuk, which Kurds consider their Jerusalem but Arabs and Turkmen also claim. An altercation on a street in the city of Kirkuk, a riot in a nearby Arab town and a car bombing shook the peace in the first half of this year, pitting Kurds against Arabs in a manner that Sunni Arab extremists are only too eager to exploit.

This is the valve train. One external gear drives each pair of camshafts, with helical gears transferring the rotation from the belt-driven camshaft (exhaust on the front head, intake on the rear head) to the partner on that bank. Notice also the spring-loaded "scissor gears" on the companion camshafts, an ingenious way of keeping gear backlash at zero so as to prevent the rattling noise so prevalent with helical cut camshaft gears.
I inspected the part of the timing belt that was visible with the balancer removed (it looked new) and slid the new pulley on the end of the crank. I then applied the necessary torque to overcome the interference fit, seat the gear and pinch it against the crankshaft boss. The key and keyway that locate the gear on the crankshaft don't have the strength to c...

GENEVA - At least 3,956 people died last year because they stepped on a land mine or other unexploded devices left behind in war, the lowest number since counting began nearly a dozen years ago, advocacy groups said Wednesday.
The report, issued at the United Nations by Mines Action Canada, Human Rights Watch and other groups, cited the casualty rate and the record amount of contaminated land cleared of mines as major progress toward a land mine-free world.

A 20-year-old soldier from Westlake Village, who had e-mailed his father to say that he loved what he was doing in Afghanistan, was killed by a land mine on Saturday, less than a month after he arrived overseas.
Army Spc. Andrew Jordan "A.J." Castro was killed along with Sgt. Patrick K. Durham, 24, of Chattanooga, Tenn., when insurgents attacked their unit in Babur, Afghanistan, the Department of Defense said. They were among 56 U.S. service members killed in August, including 19 in only four days.

The high rates of civilian casualties in global trouble spots and former war zones from land mines, other remnants of war and increasingly from cluster bombs has propelled efforts to stem the indiscriminate carnage to the top of the global arms control and humanitarian agenda.
The Land Mine Monitor Report 2007 concludes that civilians, including large numbers of children, made up three-quarters of the 5,751 casualties in 2006, which included 1,367 persons killed and 4,296 injured, with 88 classified as unknown - in 68 countries.
