Background and Purpose: Fluoride is a natural element essential for human nutrition due to its  benefits for dental enamel. It is well-documented that standard amounts of fluoride in drinkingwater can decrease the rate of dental caries. This study was conducted with the aim of measuring fluoride concentration of drinking-water supplies and urban distribution system in Qom, I...

Background: Uranium poses both chemical and radiological hazard to the living system. Drinking water from river is one of the major sources of uranium intake. Dissolution of minerals, washout from rain water, rock-water interaction, agricultural run off, and industrial disposals are some of the sources of uranium in river water system. Present study was aimed to determine the uranium in the wat...

the interline power flow controller (ipfc) is a concept of the facts controller for series compensation which can inject a voltage with controllable magnitude and phase angle among multi lines. this paper proposes a novel ipfc-based damping neuro-control scheme using pso for damping oscil la t i o ns in a power system to improve power system stability. the add i tion of a supplementary controll...
