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.
Area per Person = 0.1772 square meters per person. This would mean each person has to stand in area that is only 0.400 m by 0.443 m in size. This area in cm would be 40 cm x 44 cm. This is not enough room, because an Adult person has shoes that are around 35cm long, and shoulder width of around around 60cm.
