Background & Aims of the Study:  Environment health of schools described is one of the primary determinants of students’ health. Undoubtedly, physical environment has a very important role on the education efficiency of children in the schools and nobody can neglect the importance. The primary aim of this study was to evaluate conditions of environment health in scho...

A water environmental monitoring system based on a wireless sensor network is proposed. It consists of three parts: data monitoring nodes, data base station and remote monitoring center. This system is suitable for the complex and large-scale water environment monitoring, such as for reservoirs, lakes, rivers, swamps, and shallow or deep groundwaters. This paper is devoted to the explanation an...

Proton conduction along protein-bound "water wires" is an essential feature in membrane proteins. Here, we analyze in detail a transient water wire, which conducts protons via a hydrophobic barrier within a membrane protein to create a proton gradient. It is formed only for a millisecond out of three water molecules distributed at inactive positions in a polar environment in the ground state. T...

to examine how water retention characteristics in a landfill environment change as a result ofsolid waste settlement and to derive the evolution of pore size distribution, a lab scale long column experiment was carried out at two different time periods while keeping all the other characteristics constant. two columns, column 1 and column 2, were used in the study. the log normal distribution mo...

Toshimasa Akamatsu Noboru Oda OVERVIEW: Many countries and regions around the world are facing threats of severe water shortages or degradation of the water environment resulting from factors such as explosive population growth, rising living standards brought about by economic progress, and increasing use of industrial water. Using the advanced technologies of water treatment systems, informat...

Introduction: Due to water scarcity and increased water consumption during the past years, the importance of water in terms of transmission of diseases, as well as Iran's climate, groundwater aquifers are known as the most important resources of drinking water supply. Using the Water Quality Index (WQI) is considered as strong managerial tool for decision making in water resource management. Th...

The Lake Urmia and its satellite wetlands have been selected as a demonstration site for the United Nations Development Program / Global Environment Facility / Department of Environment Conservation of Iranian Wetlands Project. This project aims to demonstrate reduction of the major threats of this wetland protected area coordinated through an integrated management plan. A choice experiment was...

Delhi, the capital city of India is facing many problems of water shortage which are exacerbated by the population growth, urbanization, industrialization and migration. As part of the WP 7.9 of the TECHNEAU integrated project, the feasibility of the OBM process combined with river bank filtration to provide a sustainable and safe drinking water supply for Delhi is investigated within this repo...

A new locality of Ulva intestinalis was found near Krąplewo in the River Samica Stęszewska located in the Wielkopolski National Park region (Wielkopolska). On the basis of Carlson's index ranges, waters of the Samica Stęszewska river were qualified as eutrophic. In the river single thalluses of U. intestinalis which appeared by its banks were observed. The presence of this Ulva species thalluse...
