The salt enables the lamps to give out a very intense white light. A dysprosium oxide-nickel cermet (a composite material of ceramic and metal) is used in nuclear reactor control rods. It readily absorbs neutrons, and does not swell or contract when bombarded with neutrons for long periods.
Summary. Seminal vesicles are glands that produce 60% of the fluid found in semen. Seminal fluid from these glands contains sugar, prostaglandins, metals, and other components necessary to support the activity of sperm.eminal vesicles release up to 60% of the fluid found in semen. The other 40% is produced by the prostate and bulbourethral glands. The fluid produced by seminal vesicles will contain several key components: â¢ Fructose, which is a sugar that is produced to provide energy for swimming sperm cells.
Semen passes through the ejaculatory ducts and mixes with fluids from the seminal vesicles, the prostrate, and the bulbourethral glands. The seminal vesicles produce a viscous, fructose-rich fluid. This forms around 65-70% of the semen base. The white color of the semen is due to secretion from the prostate glands containing enzymes, citric acid, lipids, and acid phosphatase. This forms around 25-30% of the semen base.
