Ultraviolet guardian - real time ultraviolet monitoring
Proceedings of the 2nd ACM international workshop on Pervasive Wireless Healthcare, 2012Geographic location, environmental properties, and altitude are factors that contribute to the increase or decrease of the pedestrians ultraviolet (UV) exposure. Over-exposure can cause severe skin damage, possibly leading to skin cancer. This work proposes an algorithm for estimating the pedestrians UVA and UVB exposure along a path in an urban ...

Nosocomial Ultraviolet Keratoconjunctivitis
Infection Control, 1982AbstractA series of five successive cases of ultraviolet-induced erythroderma and keratoconjunctivitis, occurring over a one-month period and related to exposure to an improperly installed ultraviolet light are described. Although in this series, as well as others reviewed, the effects appeared self-limited, significant associated morbidity was ...

Vacuum Ultraviolet Spectroscopy
Applied Spectroscopy, 1969A review is presented on vuv spectroscopy, discussing the optics necessary, instrumentation used in absorption and emission vuv, and measurement of wavelength and intensities. Finally, several applications of the technique of interest to the chemist are presented.

Corneal Ultraviolet Phototherapy
Archives of Ophthalmology, 1962The low-pressure mercury vapor lamp has unique and highly desirable features for corneal ultraviolet phototherapy. The emitted rays are highly germicidal, 1 virtually monochromatic at 2,537 A.,1 and totally absorbed by the cornea 2 with low keratitis effect.

Ultraviolet Corneal Photoablation
Journal of Refractive Surgery, 2002ABSTRACT PURPOSE: The purpose of this article is to discuss missing information on the basic physical and biological processes of ultraviolet corneal photoablation and to evaluate its potential clinical implications. METHODS: A physical description of ultraviolet laser corneal ablation that includes photothermal, photochemical, and ...

A form of ultraviolet microscope of the refracting type is described in which the source of radiation is a spark gap between fixed or rotating electrodes and the objectives are normally monochromats. The microscope is horizontal, thus avoiding the use of a mirror, and the fine motion mechanism responds to movements of 0.10 micron. Phase contrast may be
