Childhood Brain Tumor Occurrence in Relation to Residential Power Line Configurations, Electric Heating Sources, and Electric Appliance Use

Childhood brain tumor occurrence in relation to residential power line configurations, electric heating sources, and electric appliance use.

To assess the relation between childhood brain tumor occurrence and exposure to potential sources of residential magnetic fields, a population-based case-control study of incident brain tumors was conducted in the Seattle, Washington, area at the Fred Hutchinson Cancer Research Center from 1989 to 1994 among children younger than age 20 years who were diagnosed from 1984 to 1990. The specific a...

Electric Power from Competitive Sources

Brain tumor risk in children in relation to use of electric blankets and water bed heaters. Results from the United States West Coast Childhood Brain Tumor Study.

The possible relation between the occurrence of brain tumors in children and exposure to electric blankets or electrically heated water beds was investigated in a multicenter, population-based case-control study conducted on the West Coast of the United States. Information on maternal exposure during pregnancy or direct exposure to the subject child was collected by in-person interview from the...

Distortion Sources Identification in Electric Power Systems

Distorted voltage and current waveforms is one of the problems associated to electric power quality. Continuous use of non-linear loads provokes the existence of voltage waveforms with a high distortion. Thus, it is necessary to know the responsible of this problem by means of the commonly named distortion sources identification. In this paper, the problem is analyzed through the harmonic power...

Management of electric and thermal energy consumption in residential building

In residential section, Studies have shown that, along with the use of various household consumption management techniques, the so-called hubs of energy can also be used to improve the performance and management of home energy management. In each electrical energy system, customers are aiming to minimize their energy costs. In this paper, it can be seen that in each home a home-made residential...
