Semen is produced and originates from the seminal vesicle, which is located in the pelvis. The process that results in the discharge of semen is called ejaculation. Semen is also a form of genetic material. In animals, semen has been collected for cryoconservation. Cryoconservation of animal genetic resources is a practice that calls for the collection of genetic material in efforts for conservation of a particular breed.
Luminance is a derived measure, expressed in Candela per square metre (\( cd / m^2 \)). An alias for the unit \( cd / m^2 \) (unofficial, but still commonly used) is Nit. Luminance and illumination (Lux) are related, in the sense that luminance is typically used for light-emitting surfaces and illumination for surfaces that are being lit.
The meter cubed per kilogram (symbolized m 3 /kg) is the standard unit of specific volume in the International System (SI).art of the IT standards and organizations glossary: The meter cubed per kilogram (symbolized m 3 /kg) is the standard unit of specific volume in the International System (SI). It is expressed directly in base SI units, and cannot be further reduced. Specific volume is the reciprocal of density.
