The Photochemical Nature of the Photosensory Process
1. In order to produce a response in Mya, the minimum amount of light energy required is 5.62 meter candle seconds. This energy follows the Bunsen-Roscoe law for the relation between intensity and time of exposure. 2. The necessary minimum amount of energy varies but little with the temperature; the temperature coefficient for 10 degrees C. is 1.06. 3. In view of these facts it is concluded tha...

متن کاملProtection of Archival Documents from Photochemical Eects
Purpose: The purpose of this paper is to highlight the destructive effects of light on archival documents/paper materials. The research aims to explain the mechanism of photochemical degradation and the damaging effect of light on paper. It also tells us about the measures to be adopted to control the deteriorating effects of light on paper step by step. Design/Methodology/Approach: The res...
متن کاملPhotochemical phase transition versus photochemical phase separation.
When a nematic liquid crystal is doped with a large amount of a liquid crystalline azobenzene compound (15 wt %), the photoisomerization of azobenzene under UV and visible light irradiation can give rise to reversible and interconvertible photochemical phase transition and photochemical phase separation. Both normal and reverse modes of photocontrolled switching of transmittance through crossed...
متن کاملThe Nature and Structure of Ethical Papers
Nowadays, because of their innovative and scholarly nature, the scientific-research articles are taken into account as the best and sometimes the only judging criterion of their authors and scientific community. Therefore, all those who work in the academic fields and are working as A.M. and doctorate students or teachers are required to test their proficiency and to show that they are qualifie...
