When these pockets become infected, diverticulitis occurs, a painful and, at times, serious condition. Rural Africans who consume 50 or more grams of fiber a day over a lifetime do not get diverticulosis. Yet, they do when they eat a Western diet with low fiber.
Urinary specific gravity (SG) is a measure of the concentration of solutes in the urine. It measures the ratio of urine density compared with water density and provides information on the kidneyâs ability to concentrate urine.
Jason Eardley Vocabulary density specific gravity Specific gravity is the density of a substance relative to some reference substance: Specific gravity = density of substancedensity of reference substance Specific gravity was defined because it's convenient to have a unitless measure of density.The reference substance for solids and liquids is usually water at 4Â°C. At that temperature, water has a density of 1.0000 g/mL.pecific gravity is the density of a substance relative to some reference substance: Vocabulary. density specific gravity. Specific gravity =. density of substancedensity of reference substance. Specific gravity was defined because it's convenient to have a unitless measure of density.
