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.
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.
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 ...

If the flow is not steady then when the next particle reaches position the flow would have changed and the particle will go in a different direction. This is useful, because it is usually very difficult to look at streamlines in an experiment. If the flow is steady, one can use streaklines to describe the streamline pattern.
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. Radioactive tracers are also used to determine the location of fractures created by hydraulic fracturing in natural gas production. [ 2 ]
FCS 2.0 was followed by FCS 3.0 in 1997, which introduced the possibility of storing data sets larger than 100MB. [5] The latest version, FCS 3.1, was introduced in 2010. [6] [7] It retains the basic FCS file structure and most features of previous versions of the standard. Changes included in FCS 3.1 address potential ambiguities in the ...
Fast protein liquid chromatography (FPLC) is a form of liquid chromatography that is often used to analyze or purify mixtures of proteins. As in other forms of chromatography, separation is possible because the different components of a mixture have different affinities for two materials, a moving fluid (the mobile phase) and a porous solid (the stationary phase).
