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 (Latin: glandulae vesiculosae), vesicular glands, or seminal glands, are a pair of simple tubular glands posteroinferior to the urinary bladder of some male mammals.Seminal vesicles are located within the pelvis.bout 70-85% of the seminal fluid in humans originates from the seminal vesicles, but is not expelled in the first ejaculate fractions which are dominated by spermatozoa and zinc-rich prostatic fluid.
