A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.
Disorders of sex development (DSDs), also known as differences in sex development or variations in sex characteristics (VSC), [2] [3] are congenital conditions affecting the reproductive system, in which development of chromosomal, gonadal, or anatomical sex is atypical. [4]
Ovotesticular syndrome (also known as ovotesticular disorder or OT-DSD) is a rare congenital condition where an individual is born with both ovarian and testicular tissue. [1] [2] It is one of the rarest disorders of sex development (DSDs), with only 500 reported cases. [3] Commonly, one or both gonads is an ovotestis containing both types of ...
Dilatant materials have certain industrial uses due to their shear-thickening behavior. For example, some all-wheel drive systems use a viscous coupling unit full of dilatant fluid to provide power transfer between front and rear wheels. On high-traction road surfacing, the relative motion between primary and secondary drive wheels is the same ...

Material selection is a step in the process of designing any physical object. In the context of product design, the main goal of material selection is to minimize cost while meeting product performance goals. [1] Systematic selection of the best material for a given application begins with properties and costs of
A Rockwell hardness tester. The Rockwell hardness test is a hardness test based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1]
