...This may indicate a need for more general application of aggressive air sanitation measures (e.g., upper room germicidal ultraviolet irradiation) in areas where patient care is provided and in the public areas of hospitals,” Milton and Roy wrote...
...Ultraviolet germicidal irradiation (UVGI) involves a system of light fixtures in the upper region of a room to kill infectious agents before air recirculates through a building, said SPH Lecturer on Industrial Hygiene Engineering Stephen N. Rudnick...
Diodes in the solar panels capture the sun’s ultraviolet rays, which are converted to standard AC power without generating unwanted by-products like greenhouse gases. According to the fall 2003 Harvard Green Campus Initiative newsletter, the benefits of Harvard’s new solar panel system extend beyond its ability to produce “clean” power...
Lately Kabat-Zinn has been studying a group of patients with psoriasis, an incurable skin disease that is often treated by asking patients to go to a hospital, put goggles on and stand naked in a hot, loud ultraviolet light box. Apparently, many people find this stressful. So Kabat-Zinn randomly picked half the patients and taught them to meditate in order to reduce their stress levels in the light box. In two experiments, the meditators' skin cleared up at four times the rate of the nonmeditators. In another study, conducted with Wisconsin's Richard Davidson, Kabat-Zinn gave...
...these duds do the job? Unlike sunscreen, which falls under the FDA's watch, sun-protective clothing is largely unregulated. Even so, the industry has its own voluntary standards. The weave in sun-protective clothing is extra tight, so ultraviolet rays can't penetrate. Some companies treat fabric with chemicals that reflect or absorb UV beams, in several cases using the same compounds that keep car seats from fading. That's not to say ordinary clothing can't do the trick. Off-the-rack blue jeans, for example, provide an SPF of more than 1,000. --By Janice M. Horowitz
