The erythrocyte sedimentation rate (ESR or sed rate) is the rate at which red blood cells in anticoagulated whole blood descend in a standardized tube over a period of one hour. It is a common hematology test, and is a non-specific measure of inflammation .
The Jiffy is the amount of time light takes to travel one femtometre (about the diameter of a nucleon). The Planck time is the time that light takes to travel one Planck length. The TU (for time unit) is a unit of time defined as 1024 μs for use in engineering. The svedberg is a time unit used for sedimentation rates (usually
Below is the grading system found to be most commonly used in United States public high schools, according to the 2009 High School Transcript Study. [2] This is the most used grading system; however, there are some schools that use an edited version of the college system, which means 89.5 or above becomes an A average, 79.5 becomes a B, and so on.
The build-up of plaque is also called atherosclerosis. Plaque can limit the supply of blood and oxygen to your heart tissue. Many people with early coronary artery disease don’t have any symptoms.
These avoid the ambiguity of which number stands for which type of report and whether a 1 is considered good or bad. This format originated with the U.S. military in World War II , and is currently defined by ACP 125 (G)., [ 11 ] published by the Combined Communications Electronics Board .
The sedimentation coefficient is typically dependent on the concentration of the solute (i.e. a macromolecular solute such as a protein). Despite 80+ years of study, there is not yet a consensus on the way to perfectly model this relationship while also taking into account all possible non-ideal terms to account for the diverse possible sizes, shapes, and densities of molecular solutes.

The book is a parody of the style of history teaching in English schools at the time, in particular of Our Island Story. [5] It purports to contain "all the History you can remember", and, in sixty-two chapters, covers the history of England from Roman times through 1066 "and all that", up to the end of World War I, at which time "America was ...
By the time officials concluded a conference call on Dec. 5, 1980, they hiked the target range by 2 percentage points to 19-20 percent, its highest ever. Consumer borrowing costs soared as a result.
