Arteriosclerosis, literally meaning "hardening of the arteries", is an umbrella term for a vascular disorder characterized by abnormal thickening, hardening, and loss of elasticity [3] of the walls of arteries; [4] this process gradually restricts the blood flow to one's organs and tissues and can lead to severe health risks brought on by atherosclerosis, which is a specific form of ...
Pure hydroxyapatite powder is white. Naturally occurring apatites can, however, also have brown, yellow, or green colorations, comparable to the discolorations of dental fluorosis. Up to 50% by volume and 70% by weight of human bone is a modified form of hydroxyapatite, known as bone mineral. [7]
Arteriosclerosis is a general term describing any hardening (and loss of elasticity) of medium or large arteries (from Greek ἀρτηρία (artēria) 'artery' and σκλήρωσις 'hardening'); arteriolosclerosis is any hardening (and loss of elasticity) of arterioles (small arteries); atherosclerosis is a hardening of an artery ...

Natural substances such as magma, lava, gums, honey, and extracts such as vanilla extract Biological fluids such as blood , saliva , semen , mucus , and synovial fluid Slurries such as cement slurry and paper pulp, emulsions such as mayonnaise, and some kinds of dispersions
Semipermeable membrane is a type of synthetic or biologic, polymeric membrane that allows certain molecules or ions to pass through it by osmosis. The rate of passage depends on the pressure, concentration, and temperature of the molecules or solutes on either side, as well as the permeability of the membrane to each solute.
The former CEO of Abercrombie & Fitch (A&F) has dementia and late onset Alzheimer's disease, his legal team has said in a court document filed in New York.
The plastic must then be cured with gas, heat, or ultraviolet light, to harden it. [4] Specimens, which can vary from a full human body to a small piece of an animal organ, are known as 'plastinates'. [citation needed] Once plastinated, the specimens and bodies are further manipulated and positioned prior to curing (hardening) of the polymer ...
