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 consists of spermatozoa (sperm) from the testis, and seminal fluid secreted by â¦ the accessory glands of the male reproductive tract: the seminal vesicles, prostate gland, and the bulbo-urethral glands (known as 'Cowper's glands').uring the process of ejaculation, sperm passes through the ejaculatory ducts and into the urethra, it mixes with fluids produced in the seminal vesicles, the prostate, and the bulbourethral glands to form the semen.
