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.
Normal levels of creatinine and BUN. Te normal range for creatinine in the blood may be 0.6 to 1.3 milligrams per deciliter (53 to 115 micromoles per liter), although this can vary from lab to lab, between men and women, and by age. Since men usually have high larger muscle mass, the amount of creatinine in the blood is often higher than women. In general,the normal BUN level ranges from 7 to 20mg/dL(2.5 to 7.1mmol/L).However, the normal BUN levels may vary with the lab, and your age.
