The Cherenkov effect A charged particle traveling in a dielectric medium with n>1 radiates Cherenkov radiation if its velocity is larger than the phase velocity of light v>c/n or Î² > 1/n (threshold) The emission is due to an asymmetric polarization of the medium in front and at the rear of the particle, giving rise to a varying electric dipole momentum.
cyclo-. 1. Combining forms relating to a circle or cycle; or denoting an association with the ciliary body. 2. In chemistry, a combining form indicating a continuous molecule, without end, or the formation of such a structure between two parts of a molecule.
Definition. Cyclosporiasis refers to infection by the sporeforming protozoan known as Cyclospora. Protozoa are a group of parasites that infect the human intestine. Parasites are organisms that live in another body, called the host, and get food and liquids from that host.yclosporiasis. Infection with Cyclospora. /cyÂ·cloÂ·spoÂ·riÂ·aÂ·sis/ (-spah-riÂ´ah-sis) infection by protozoa of the genus Cyclospora, especially C. cayetanenÂ´sis, seen especially in immunocompromised patients and occurring as recurrent gastrointestinal disease and watery diarrhea.
