Description:
This paper develops and tests a comprehensive model to explain the relationships of neighborhood economic indicators to multiple dimensions of neighborhood social and physical organization as well as the pathways through which neighborhood social and physical characteristics influence individual health outcomes. We hypothesized that neighborhood poverty would be associated with lower collective efficacy, lower social capital, higher degrees of social and physical disorder, worse social processes pertaining to children such as trust, and higher degrees of fear of crime and racism. Neighborhood social and physical characteristics were hypothesized to mediate the effect of neighborhood poverty on self-rated health, both directly and indirectly through their influence on neighborhood differences in social support and health behaviors, which in turn affect individual health. The results, based on data from low-income neighborhoods in Texas, USA generally supported the model and indicated that the effect of neighborhood impoverishment on health is mediated by social and physical neighborhood characteristics. .

IEC/TS 61000-3-4 Ed. 1.0 b:1998, Electromagnetic compatibility (EMC) - Part 3-4: Limits - Limitation of emission of harmonic currents in low-voltage power ... with rated current greater than 16 A
The recommendations of this technical report are applicable to electrical and electronic equipment with a rated input current exceeding 16 A per phase and intended to be connected to public low-voltage a.c. distribution systems of the following types: - nominal voltage up to 240 V, single-phase, two or three wires; - nominal voltage up to 600 V, three-phase, three or four wires; - nominal frequency 50 Hz or 60 Hz. These recommendations specify the information required to enable a supply authority to assess equipment regarding harmonic disturbance and to decide wether or not the equipment is acceptable for connection with regard to the harmonic distortion aspect. This document is not to be regarded as an International Standard..
