Sedimentation Rate - an overview | ScienceDirect Topics

Parasite sedimentation rates (estimated using Stoke's law for discrete particle settling) will vary between parasite species depending on the specific gravity and dimensions of the parasite and liquid density (and temperature) suggesting that eggs of Ascaris and Trichuris will be removed more effectively than eggs with slower rates of settling velocity, such as hookworm and (oo)cysts of protozoa (Table 31.2).

Inflammation, as measured by the erythrocyte

Objectives: Our objective was to explore inflammation, measured as erythrocyte sedimentation rate (ESR), as a predictor for the development of heart failure (HF). Background: In recent years, evidence of the importance of inflammation in the pathophysiology of HF has emerged, and various inflammatory markers have been found to predict future HF.

Sedimentation - Marlborough District Council

Sedimentation of estuaries and seabed habitats is a natural process, caused by slips in native forest. However, our activities on land and in the sea have accelerated erosion rates and led to dramatically increased rates of sediment entering our waterways. Excessive sedimentation is can smother habitats and thereby change ecological composition ...
