PENETRATION OF EPIDERMIS BY ULTRAVIOLET RAYS
Photochemistry and Photobiology, 1966Abstract— The u.v. transmission characteristics of various epidermal specimens prepared by various methods were measured by a recording spectrophotometer and integrating spheres. Although suction or stretch and heat produced the most satisfactory specimens, transmission data obtained from all specimens were similar and generally resembled that reported

Archives of Dermatology and Syphilology, 1936
The phenomenon of fluorescence noted in many substances when they are observed under filtered ultraviolet rays is of great value to the dermatologist. Margarot and Deveze 1 first drew attention to the value of the rays as a diagnostic measure in infections of the scalp with Microsporon. Other observers 2 have confirmed their observations.

STANDARDIZATION OF ULTRAVIOLET RAYS
Journal of the American Medical Association, 1926Heliotherapy has gained more and more advocates among the medical profession in the last few years. There is no denying the fact that ultraviolet radiation intelligently used in favorable cases has shown encouraging results. The amount of radiation administered in a single treatment or the total energy applied in a series of treatments varies widely ...

ULTRAVIOLET RAYS FOR FINGER PRINTING
JAMA: The Journal of the American Medical Association, 1927To the Editor: —Having observed the rapidity with which the soluble silver salts become decolorized in the presence of organic fatty acids under the action of the middle chain of ultraviolet rays, I wondered whether or not it could be used as a rapid method of finger-printing.

Ultraviolet and X-Ray Spectroscopy
1998The higher the energy of the electromagnetic radiation the deeper we can look into the atoms and into the band structure of solids. Thus, for ultraviolet radiation and x rays a new area opens up for spectroscopic investigations. It becomes possible to analyze the structure of the valence band and of lower bands down to the core levels.

ULTRAVIOLET RAY THERAPY IN DERMATOLOGY
Archives of Dermatology, 1924Twenty-seven years have elapsed since Finsen introduced ultraviolet ray therapy in the treatment of lupus vulgaris and other cutaneous affections. It would seem reasonable to believe that in view of the many experiments since that time in the application of these rays by numerous apparently qualified observers, there would be a reasonable unanimity of ...

PITYRIASIS VERSICOLOR AND ULTRAVIOLET RAYS
Archives of Dermatology and Syphilology, 1927The changing conditions of life bring about corresponding changes in the development of pathologic and physiologic processes. The period of starvation in the United States of Soviet Russia from 1918 to 1920 is a typical instance. There was a complete disappearance of disturbances of metabolism, gout and excessive obesity, and an increase in scurvy and
