Ultraviolet Light UV light is a nonthermal, nonchemical intervention technology that employs physical light energy at wavelengths of 200–290nm to inactivate microorganisms. The germicidal effects of UV irradiation are a result of DNA mutations to the bacterial cells induced by the absorption of UV ...
- **选项B**:名词短语"a painful redness...",可作同位语,正确补充说明"Sunburn",符合语法。 - **选项C**:包含谓语动词"is",与后半句的"is caused"形成两个谓语,语法冲突。 - **选项D**:"when..."为时间状语从句,逻辑不符且倒装结构错误。 故选B,句子结构为:Sunburn, (同位语), is caused...,...
light regulation of the aggregation and dissociation of metal-bound Aβ peptides remains to be explored. The brains of Alzheimer’s disease (AD) patients are characterized by the deposition of amyloid plaques whose main component is Aβ peptides. Aβ42is more neurotoxic and has a higher ...

Abstract: A set of goggles provides ultraviolet (UV) light filters (B) made of plastic and according protection fro UV-light from all angles. The nose bridge is fabricated from a UV-transparent material. The UV goggles are fixed (A) to the head by a strap or cord. ...
monoxide by ultraviolet light. The results of the work presented here favor the alteration of oxygen isotopes in a molecular cloud environment. The white scale bar is 5 light years or 300,000 AU (astronomical units, the distance between the Earth and Sun). Credit: NASA, ESA, Hubble Heritage...
An Ultraviolet-C (UVC) based portable water purification system employing a novel array of baffles increases the efficiency per unit energy of irradiating UVC light in the eradication of pathogens in the water. Closed loop feedback allows monitoring the application of UVC light power to ensure ...
