Cell Size and Scale - University of Utah

How can an X chromosome be nearly as big as the head of the sperm cell? No, this isn't a mistake. First, there's less DNA in a sperm cell than there is in a non-reproductive cell such as a skin cell. Second, the DNA in a sperm cell is super-condensed and compacted into a highly dense form. Third, the head of a sperm cell is almost all nucleus.

Sand vs Glass Pool Filter Media, Which is Better?

Sand will filter to roughly 30 microns. Some glass media manufacturers state that the glass will filter down to 5 - 10 microns which is less than a cartridge filter. We aren't sure about those claims, however it does filter better than sand as the sand is negatively charged and allow smaller particles to cling better than the sand.

M Sand (Manufactured Sand) - A Substitute to River Sand

M Sand has higher Fineness Modules Index compared to the natural river sand, which gives good workability for concrete. M sand is free from silt and clay particles which offer better abrasion resistance, higher unit weight and lower permeability. Less disruptive to the environment, as it reduces sand mining from river beds.

Manufactured Sand vs. Natural Sand - Chaney Enterprises

Natural sand has an ideal shape for use as fine aggregate in concrete. The natural sand particles are well-rounded and are usually nearly spherical. Spherical particles decrease the percentage of voids within the concrete mixture so no additional paste is required to fill these voids. Well-shaped natural sands are ideal for workability of mixtures.
