Rain Water Treatment by Ultraviolet Radiation Using Photovoltaic Energy

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 ...

Fuzzy Energy Management for Photovoltaic Water Pumping System

A Fuzzy energy management algorithm for a photovoltaic water pumping installation is presented and validated experimentally, using a plant composed of photovoltaic panels, battery banks, DC/AC converters, relays and a water pump. Considering many criteria related to the battery safe operation, fulfilling the water volume needed by the crops and ensuring a continuous function of the pump, the al...

Ultraviolet Radiation Induced Desorption of Water from Martian Soil

The composition and pressure of the martian atmosphere allows solar ultraviolet photons as short as 190 nm to penetrate to the surface. The effects of UV photons on the hydration state of minerals has been investigated in the past with mixed results. Andersen and Huguenin [1977] proposed that photons with wavelengths shorter than 280 nm release water from goethite by ejecting OHgroups which sub...

Living in flowing water increases resistance to ultraviolet B radiation.

Ultraviolet B radiation (UV-B) is an important environmental driver that can affect locomotor performance negatively by inducing production of reactive oxygen species (ROS). Prolonged regular exercise increases antioxidant activities, which may alleviate the negative effects of UV-B-induced ROS. Animals naturally performing exercise, such as humans performing regular exercise or fish living in ...
