  • Motors in Radiation-Intensive Environments
    , the significance of the new dissolver design is threefold: greater efficiency due to the multistage, continuous design; substantial cost savings as a result of minimizing radioactive waste generation; and conservation of a natural resource that is being effectively recycled. This article originally appeared
  • Ultrafast Laser Pulses Reveal DNA's Natural "Sunscreen"
    COLUMBUS -- Researchers at Ohio State University have glimpsed for the first time how DNA protects itself from the sun's harmful radiation. Through a natural process that lasts less than one trillionth of a second, light-absorbing parts of DNA convert ultraviolet (UV) radiation from the sun
  • Power converter application notes - heat radiation in design
    the life time of a power converter, and reduce the possibility of failure or safety issues. This article will discuss heat radiation design in power converter applications. * Typical heat radiation design applications. Natural convection. Limited by size, the majority of high power density and miniature
  • Sensor Could Detect Concealed Weapons Without X-Rays
    machines or radar instruments, the sensor doesn't have to generate a signal to detect objects - it spots them based on how brightly they reflect the natural radiation that is all around us every day. There is always a certain amount of radiation - light, heat, and even microwaves - in the environment
  • A field-study of inducible molecular defenses, ultraviolet
    Ultraviolet radiation-the primary natural. pollutant affecting melanomagenesis-may represent. a widespread ecological stressor for many fishes, and. yet the relationship between UV-exposure and stress. has not been investigated in natural fish populations. Recent lab-based studies have sought
  • Monitoring Fugitive Dust
    The term fugitive dust refers to particulate that is lifted into the air either by man-made or natural activities in large open areas. Fugitive dust is typically the result from activities such as the physical movement of soil, vehicles traveling over unpaved surfaces, heavy equipment operation
  • Atlas Fade-Ometer Identifies Cause of Degradation and Sets Standard For Firefighter's Turnout Gear

  • UV Properties of Plastics: Transmission and Resistance (.pdf)
    ). One useful interaction of UV and plastics can be as fluorescent whitening agents (FWA). In. natural light many polymer products can appear to have a yellow appearance. By including a. special additive, the UV light absorbed is then emitted in the 400-500 nm range (the blue region. of visible light
