Nickel: the essentials. Nickel is found as a constituent in most meteorites and often serves as one of the criteria for distinguishing a meteorite from other minerals. Iron meteorites, or siderites, may contain iron alloyed with from 5 to nearly 20% nickel. The USA 5-cent coin (whose nickname is nickel) contains just 25% nickel.

Von Willebrand's disease (vWD) is a common, usually mild, inherited bleeding disorder in people and in dogs. It is caused by a lack of von Willebrand factor (vWF), which plays an essential role in the blood clotting process.Normally the body responds to an injury causing bleeding through a complex defence system.ecause the severity of bleeding with von Willebrand's disease is quite variable, often the disease is not diagnosed until the dog is 3 to 5 years old. Your veterinarian may suspect vWD because of a history of abnormal bleeding in your dog, such as unexplained nosebleeds, or there may be heavy bleeding during surgery.
