Some Studies on Content of Ultraviolet Rays in Conventional Light Sources vs LED
Abstract: The abstract Light is a type of electromagnetic radiation that primarily emits visible, ultraviolet (UV), and infrared (IR) waves. Which is known as optical radiations. The Ultra Violet radiations in this spectrum, which are generically classed as UV-A, UV-B, and UV-C. It's true that UV[1]-shorter C's wavelength has more harmful effects than UV-A while UV-impact B's is more moderate. Whether artificial or natural, light is used to create visual perception. …

IMPACT OF HYDRATED LIME AND SBS ON HMA MOISTURE SUSCEPTIBILITY
Abstract: Abstract In recent years, many of the newly built asphalt and concrete roads in Baghdad and other Iraqi cities have broken down too soon. This has hurt the country's economy and public safety. One of the main reasons why these newly built roads break down is because of water damage. Leaking water weakens the bond between the aggregate and the asphalt, which makes it more likely that sidewalks will fall …
