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.
In many mammal bodies, including those of humans, the majority of this fluid is produced in the seminal vesicle, or more accurately, it is made by the two seminal vesicles. These are glands of a couple inches (approximately five centimeters) in length located behind the bladder. Amount of seminal fluid mammalian species derives from each seminal vesicle with each ejaculation varies, but in humans it runs an average of 60% for both vesicles.
