If you've always wondered how alloy wheels were made, then check out this interesting tour of the Ray's Engineering factory in Japan. Video after the jump. Aluminium alloys or aluminum alloys are alloys of aluminium, often with copper, zinc, manganese, silicon, or magnesium.
Urea is transported to the kidneys for excretion. A normal range for blood urea nitrogen is generally 8 to 24 mg/dl for adult males and 6 to 21 mg/dl for females. Generally, a high blood urea nitrogen level means that the kidneys are not performing well, particularly if the result is above 50mg/dl.
The creatine kinase normal range varies from males to females. For adult males, the normal values are between 38 and 174 units per liter of blood whereas for adult females, the normal level is between 90 and 140 units per liter of blood. An elevation beyond this point is likely to be diagnostically relevant.
