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.
Confidence votes 162. Normal findings (in mg/dL) are 10 to 20 for adults, 5 to 18 for children and infants, 3 to 12 for newborns, and 21 to 40 for cord blood. In the elderly, the blood urea nitrogen may be slightly higher than the normal adult range. while a maximum limite of a normal range can reach 25 mg/100 ml.n abnormally high blood urea nitrogen (BUN) level may indicate  damage to the kidneys and a decreased ability to properly remove  nitrogenous waste from the blood in your u â¦ rine.
