Specifier Reports: Photosensors (March 1998)

A photosensor is an electronic control device that adjusts the light output of a lighting system based on detected illuminance. While some photosensors simply switch lights on and off, Specifier Reports: Photosensors focuses on photosensors that are used with dimming electronic ballasts to adjust the light output of fluorescent lighting systems over a continuous range. These photosensors are mo...

Global Tectonic Regionalization for Seismological Data Analysis

A global tectonic regionalization, GTR1, has been constructed for use in seismological studies of aspherical heterogeneity. Three oceanic regions are defined by equal increments in the square root of crustal age (25and lO0-m.y. isochrons), and three continental regions are distinguished according to their generalized tectonic behavior during the Phanerozoic (Precambrian shields and platforms, P...

consideration of quarantine conditions in bushehr between 1905 and 1915, based on baliuz of britain reports

prevalence of contagious diseases through foreign passengers and crews is one the serious problems in big ports. in the late qajar period, bushehr port became an important port because of military, political and economical reasons. in this time, some diseases such as plague and cholera prevailed in some iran’s neighbor countries like india and iraq and spread in bushehr by passengers and crews....
