Controls on pyrite sulfur isotopes during early diagenesis in …

As sedimentation rates increase, greater amounts of organic matter are buried at deeper depths, thereby promoting the formation of subsurface pyrite with the lowest δ 34 S values. In case of a down-core decreasing of δ 34 S py values, we deduce that higher sedimentation rates and higher organic matter supply results in overall lower δ 34 S ...

Impact of small ice crystal assumptions on ice sedimentation rates …

Ice clouds are particularly challenging, and to date there is no accepted method for measuring the smaller ice crystals (D < 60 μm). This study examines the sensitivity of a global climate model to different assumptions regarding the number concentrations of small ice crystals when they are allowed to affect ice sedimentation rates.

Basic Theory of Particle Size Analysis by Sedimentation

diffusion is comparable to the sedimentation rate. Very small particles (<0.1 micron) never settle by gravity unless they are extremely dense, so most types of very small particles can not be measured by gravitational sedimentation. Sedimentation in a centrifuge extends the range of sedimentation analysis to much smaller particles.

Erythrocyte Sedimentation Rate: Test, Ranges, Rate, and …

A sedimentation rate, or erythrocyte sedimentation rate blood test, is a common blood test that is used to detect and monitor inflammation in the body. The sedimentation rate is also called the erythrocyte sedimentation rate because it is a measure of the red blood cells (erythrocytes) sedimenting in a tube over a given period of time.

Sedimentation

The sedimentation rate is the time that red blood cells take to settle at the bottom of a thin, vertical tube. Red blood cells tend to sediment more quickly when the blood contains proteins associated with the inflammatory response, such as C-reactive protein and others. The sedimentation rate is an indirect measure of the degree of acute or chronic inflammation that affects an individual ...
