Limitations of use in acidic waters; Depending on the environment, water flows possess certain factors that can affect how a dye performs. Natural fluorescence in a water flow can interfere with certain dyes. The presence of organic material, other chemicals, and sunlight can affect the intensity of dyes.
Radioisotopes of hydrogen, carbon, phosphorus, sulfur, and iodine have been used extensively to trace the path of biochemical reactions. A radioactive tracer can also be used to track the distribution of a substance within a natural system such as a cell or tissue , [ 1 ] or as a flow tracer to track fluid flow .
Rouleaux (singular is rouleau) are stacks or aggregations of red blood cells (RBCs) that form because of the unique discoid shape of the cells in vertebrates. The flat surface of the discoid RBCs gives them a large surface area to make contact with and stick to each other; thus forming a rouleau.
Erythrocyte aggregation is the reversible clumping of red blood cells (RBCs) under low shear forces or at stasis. Stacked red blood cells flow across drying slide. Erythrocytes aggregate in a special way, forming rouleaux. Rouleaux are stacks of erythrocytes which form because of the unique discoid shape of the cells in vertebrate body. The ...

You shouldn’t wear compression socks in bed unless prescribed by your doctor, as they can block blood flow, especially when lying down. Other factors to keep in mind: Try to change your socks ...
In some instances, he said, “bots distort judicial decisions, using fake or exaggerated narratives to foment discord within our democracy.” ...
Gaussian plume models can be used in several fluid dynamics scenarios to calculate concentration distribution of solutes, such as a smoke stack release or contaminant released in a river. Gaussian distributions are established by Fickian diffusion , and follow a Gaussian (bell-shaped) distribution. [ 14 ]
