Ultraviolet light and ultraviolet light-activated composite resins
The Journal of Prosthetic Dentistry, 1981In a comparison of the UV light--activated composite resins, Estilux was polymerized to a significantly greater depth than the other composite resins. In general, Lee-fill polymerized the least. When comparing the UV light sources, the Lee light and the Duralux light did not significantly differ from each other, but both polymerized the materials ...

Journal of Food Science, 2000
Scope of Deliverables: This section covers information, where available, on microbial kinetics and relevant safety considerations when ultraviolet (UV) radiation is used for the purposes of food preservation. The section pays particular attention to the growing interest in using UV light to treat fruit juices, especially apple juice and cider.

Ultraviolet light absorbing pseudophakos
American Intra-Ocular Implant Society Journal, 1982We evaluated a new compound of polymethylmethacrylate (PMMA) that effectively blocks radiation below 380 nm, while maintaining nearly ideal transmittance characteristics above this wavelength. Our in vitro studies demonstrated no toxicity from this compound.

Dichroic ultraviolet light filters
Applied Optics, 2003With the intention to produce dichroic filters for use in photoluminescent systems that rely on polarized UV light, we synthesized a number of linear, dichroic dyes, which absorb mainly in the near-UV range of the electromagnetic spectrum. These dyes were designed for compatibility with common thermoplastic polymers such as linear low-density poly ...

We believe that at the present time most physicians in prescribing ultraviolet light determine the dosage by looking at a patient and estimating whether the skin is dark or light and asking him whether he is easily burned or tanned in the summer on exposure to the sun. With the diagnosis and the effect from the light which is desired in mind, we decide

JAMA: The Journal of the American Medical Association, 1981
ABSTRACT To the Editor.— I would like to commend Lewis H. Kaminester, MD (1980;244:1258), for warning the readers of JAMA about the possible hazards of suntanning centers. However, I must disagree with his statement that psoriasis and pityriasis rosea are the only diseases for which ultraviolet (UV) light has proved beneficial. Dermatologists have used

Keratoconjunctivitis From Ultraviolet Light
JAMA: The Journal of the American Medical Association, 1980To the Editor.— The report of keratoconjunctivitis in nursing personnel exposed to ultraviolet rays emitted by an inappropriate bulb in a desk lamp (242:1155, 1979) is important because of the increased use and availability of bacteriocidal ultraviolet lamps.

Science, 1925
Three experiments with different scorbutic diets showed that ultraviolet radiation is entirely ineffectual in preventing or postponing scurvy. With diets in which other factors, besides the scorbutic vitamin, were lacking, ultraviolet light hastened loss of weight and death from scurvy somewhat and prevented recovery after orange and cabbage were added
