sedimentation rates measure
Svedberg Unit
The sedimentation rate is a measure of how quickly a particle sediments from a solution or suspension under the induced gravitational field of a centrifuge. The sedimentation coefficient is the ratio of the speed of a substance in a centrifugal field to its acceleration in comparable units.

Measuring Inflammation: Erythrocyte Sedimentation Rate (ESR
The C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) are both blood tests used to measure inflammation in the body. We look at the relation between the two, ranges, symptoms, treatment options, how to prevent high ranges, and the connection to inflammation and autoimmune diseases.

Erythrocyte Sedimentation Rate (ESR) | Stanford Health Care
Erythrocyte Sedimentation Rate (ESR) An erythrocyte sedimentation rate (ESR) is a measurement of how quickly red blood cells fall to the bottom of a test tube. When swelling and inflammation are present, the blood's proteins clump together and become heavier than normal. Thus, when measured, they fall and settle faster at the bottom of the test ...

SEDIMENTATION
The constant rate period corresponds to pulp settling at its initial concentration. During the final falling rate section the pulp is in compression. Point C is known as the compression point or the critical sedimentation point, and identifies the point at which the pulp-supernatant interface goes from zone settling into compression.

The sedimentation rate, also known as the deposition rate (D R), is the vertical flux of sediment to the depositional surface, such as the seafloor in the case of a marine environment (e.g., kg/m 2 per year). Sedimentation rates vary across time, because periods of rapid sedimentation alternate with periods of slower deposition, …
