Magnetization of Matter by Ultra–violet Radiation

Disinfection of sea water by ultraviolet radiation.

Evaluation of solar ultraviolet radiation in Zanjan city using the ultraviolet index

Background and Objective: Monitoring the amount of ultraviolet radiation from sunlight can provide a basis for assessing people's exposure, raise public awareness and warn people against this radiation. Measuring the sun's ultraviolet index over a working period is an accurate choice to achieve this goal. Materials and Methods: In this study, the amount of solar UV index in one of the outdoor ...

photodegradation of atrazine by ultraviolet radiation in different conditions

background: atrazine is one of the most widely used triazine herbicides which has been used for controlling broadleaf and grassy weeds for many years. its widespread use in water has caused environmental concern because of frequent detection of atrazine in aquatic systems where this herbicide has been spilled. therefore, the purpose of this study was to determine the herbicide removal efficienc...

The Bystander Effect of Ultraviolet Radiation and Mediators

A bystander effect is biological changes in non-irradiated cells by transmitted signals from irradiated bystander cells, which causes the radiation toxic effects on the adjacent non-irradiated tissues. This phenomenon occurs by agents such as ionizing radiation, ultraviolet radiation (UVR) and chemotherapy. The bystander effect includes biological processes such as damage to DNA, cell death, ch...

Ultraviolet Radiation

another in the animal body. The full demonstration of the importance of transmethylation and of its relationship to the metabolism of choline, betaine, creatine, sarcosine, and a number of other methylated substances involved research that extended over a number of years. The discussion forms the subject matter of three of the chapters and requires considerably more than one-half of the book. I...
