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.
seminal vesicle and prostate gland and bulbourethral gland release seminal fluid an alkaline, fructose rich fluid that neutralizes vaginal acidity; prostate gland also releases a milky fluid with citric acid, seminalplasmin, and prostate-specific antigen; bulbourethral glands produce mucin which forms into mucus and mixes with sperm to protect the urethra and lubricate; together these substances mixed with the sperm form semen, which exits by ejaculation through the urethra
