in a steam power plant, the temperature of the cooling water leaving the condenser for recyclingshould decrease. this is achieved in a cooling tower. the heller cooling tower does not require waterfor operation, thus, it is a suitable system for use in thermal power plants throughout iran. wind is anenvironmental factor that unfavorably affects the performance of a cooling tower. previous studi...

The present study applies the model of American Meteorological Society-Environmental Protection Agency Regulatory Model (AERMOD) to investigate NO2 emissions from Besat thermal power plant, which is fuelled by natural gas to function. Results indicate that the simulated concentration of NO2 based on AERMOD, does not exceed NO2 concentration limit, set by the Iranian Ambient Air Quality Standard...

The objective of the present study was to assess the intake of naturally occurring plant sterols and β-carotene via the overall diet of Belgian pre-school children and adults. Two different Belgian food consumption databases were used: (1) one with consumption data of pre-school children (2·5-6·5 years old) and (2) one with consumption data of adults ( ≥ 15 years old). These consumption data we...

The concentrations of Cs and potassium in the surface layers of arable soils were analyzed in the selected region of Eastern Poland approximately 20 years after the Chernobyl power plant accident. Additionally, the occurrence of the elements in soil in the forms available for plants was determined. In relation to the total concentrations of Cs and K in the soil, cesium is found in larger quanti...

OBJECTIVE Reduction in the current high levels of meat and dairy consumption may contribute to environmental as well as human health. Since meat is a major source of Fe, effects on Fe intake need to be evaluated, especially in groups vulnerable to negative Fe status. In the present study we evaluated the effects of replacing meat and dairy foods with plant-based products on environmental sustai...

In the last decade nuclear reactors have proven to be a source of electrical energy economically competitive with conventional means of power production. With the resulting increase in orders for nuclear power stations there has been a corresponding increase in public awareness of the safety and environmental aspects of these facilities. This public awareness has been evidenced by the number of...
