Ultraviolet Light
Ultraviolet light (UV) is a recognized disinfection alternative to chlorine and ozone in many applications from drinking water to wastewater treatment. UV provides effective disinfection without production of problematic disinfection byproducts. Information on the mechanism and application of UV for drinking water disinfection is presented. Advantages and disadvantages of the technique are disc...
متن کاملUltraviolet light and pterygium.
The purpose of this study was to evaluate the contribution of ultraviolet light (UV) as a causal factor of primary and pterygium recurrence. A conjuctival autograft transplantation was a surgical method of pterygium treatment. In the first group (38 eyes) were patients with primary and recurrent pterygium exposed to sun (worked outdoors), evaluating geodemographic status, and in the second grou...
متن کاملAzobenzene photoswitching without ultraviolet light.
Most azobenzene-based photoswitches use UV light for photoisomerization. This can limit their application in biological systems, where UV light can trigger unwanted responses, including cellular apoptosis. We have found that substitution of all four ortho positions with methoxy groups in an amidoazobenzene derivative leads to a substantial (~35 nm) red shift of the n-π* band of the trans isomer...
متن کاملUltraviolet Light and Reptiles, Amphibians
Ultraviolet lighting is integral for the growth and maintenance of many reptile and amphibian species. But providing an adequate source of light can be challenging. Many disease processes seen by veterinarians are attributed to ultraviolet lighting deficiencies. In mammals, disease due to excess ultraviolet lighting has been noted, and some veterinarians feel this may be a potential issue in re...
متن کاملEnhanced experimental metastasis of ultraviolet light-induced fibrosarcomas in ultraviolet light-irradiated syngeneic mice.
Some ultraviolet light (UV)-induced fibrosarcomas produce more experimental pulmonary tumor colonies in UV-irradiated hosts than in normal syngeneic recipients. The number of experimental metastases produced following i.v. injection of these tumors increases in proportion to the dose of UV radiation. This enhancement can be transferred with lymphoid cells to lethally X-irradiated recipients and...
