Too much UV light can burn your skin in the short term and raise your risk for skin cancer in the long term. UV index is a color-coded scale that gives you an idea of your UV ray exposure. It works like this: Low exposure (green): 1-2 Moderate exposure (yellow): 3-5 High expo...
UV index (yo͞o′vē′) n. A scale ranging from zero to eleven or above, used to estimate the risk for sunburn on a given day in a specific location at midday, taking into account conditions such as cloud cover and the amount of ozone. ...
as often is the case, unknown trade-offs influence this evolution, a strong association with exposure to UV radiance is present. As a result, black skin tends to be more common towards the equator, an ecogeographic rule known as Gloger’s rule. ...
Using viscous timescale arguments we rule out the possibility that the UV variation is due to the fluctuating accretion rate in the outer disk. If the UV variation is driven by X-ray reprocessing, then our results indicate that the strength of the X-ray reprocessing depends more on the ...

(UV) radiation. This form of electromagnetic radiation has shorter wavelengths than visible radiation. The Grove - UV Sensor is based on the sensorGUVA-S12Dwhich has a wide spectral range of 240~370nm. You can also use it to measure the UV Index which provides a scale to determine how ...
Preserves the shape of any existing UV islands (allowing them to rotate or scale), and re-flattens their interior UVs. You can turn on this option and Preserve layout if you want to preserve existing islands in-place but relax their UVs. Flattening constraints ¶ Seams When Enable manual...
The secondary reflection of UV-ray from highly reflective surface must be critical consideration during the development of disinfection devices. For example various materials such as stainless-still, aluminium, PTFE surfaces have very high reflectance properties of 50%, 90% and 95% respectively. ...

For the purpose of this study, we have designed a small-scale kerosene pool fire which consists in a round container of kerosene with a diameter of 50 mm and 20 mm height. Such an experimental set-up enables the production of a constant soot emission from a defined volume of fuel. Soot...
