Inactivation of Bacteria by Ultra-violet Radiation

Radiation from the sun has different effects upon living organisms. It has been found, for instance, that ultra-violet rays of a certain wavelength present in the radiation from the sun stop the multiplication of bacteria and other micro-organisms. Good use can be made of this, without having to depend upon sunlight, by employing a low-pressure, mercury-vapour lamp emitting rays which have a sp...

Ultra-Violet Radiation and Actino-Therapy

This little book, written in a charming literary style, is an exposition of our knowldege of radiation in general and the application to medicine of the rays of that part of the spectrum known as the ultra-violet region. In his foreword Sir Oliver Lodge says it is a book dealing with a comparatively new and highly promising subject by people with medical training, physical knowledge, and extens...

Physical-Mechanical Properties of Nitrodopes Affected by Ultra-Violet Radiation

The FTIR spectroscopy has been employed in this research work to monitor theprocess of nitrodope photodegradation, by measuring surfaces of bands typical of a nitrogroup. Nitric esters are subject to degradation, which is reflected on a quantitative ratio ofthe surfaces of the IR bands that originate from the nitric ester. The obtained results showthat the length of the UV rays' activity on the...
