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.
The seminal vesicles are convoluted pouch-like structures lying posterior to the base of the urinary bladder, in front of the rectum. They secrete an alkaline viscous fluid co â¦ ntaining fructose, prostaglandins and fibrinogen that make up about 60% of the fluid volume of semen.he seminal vesicleis a male-specific structure which is about 2 inches or 5 centimeters long and is located behind the urinary bladder and above the prostate gland.
