Definition. Protein in urine â known as proteinuria (pro-tee-NU-ree-uh) â is any excess amount of protein found in a urine sample. Protein is one of the substances identified during urinalysis, a test to analyze the content of your urine. Low levels of protein in urine are normal. Temporarily high levels of protein in urine aren't unusual either, particularly in younger people after exercise or during an illness. If a urinalysis shows you have protein in your urine, you might have a follow-up test that determines how much protein is present and whether it's a cause for concern.
aerodynamics definition. The branch of science devoted to the study of the flow of gases around solid objects. It is especially important in the design of cars and airplanes, which move through the air. Note: A vehicle that has been built to minimize friction with the air is said to be aerodynamically designed.
Aerodynamics, from Greek á¼Î®Ï aer (air) + Î´ÏÎ½Î±Î¼Î¹ÎºÎ® (dynamics), is a branch of Fluid dynamics concerned with studying the motion of air, particularly when it interacts with a solid object, such as an airplane wing.n aerodynamics, hypersonic speeds are speeds that are highly supersonic. In the 1970s, the term generally came to refer to speeds of Mach 5 (5 times the speed of sound) and above. The hypersonic regime is a subset of the supersonic regime.
