Week Day and Week End Air Ion Variability at Rural station Ramanandnagar (17° 4’ N 74° 25’E), India and At Different Atmospheric Sites in India
General
Globalization and liberalization polices of the government of India have increased the number of road vehicles nearly 92.6% from 1980-81 to 2003-2004. Therefore to know whether there is effect of increase of industrialization in the urban areas like Pune (18° 32′N, 73° 51′E); Mumbai (18° 55' N, 72°...
Multivariate analysis of hydrochemical data of the groundwater in parts of Karwan – Sengar sub - basin, Central Ganga basin, India
General
Ganga basin is one of the world’s biggest aquifer repositories. The thick alluvium of the basin hosts its three tier aquifer system. The aquifer of the basin is under high stress due to unethical human intervention in the natural system. This warrants the need to evolve the basic hydrochemistry of...
Evaluating landslide susceptibility using environmental factors, fuzzy membership functions and GIS
General
A methodology for landslide susceptibility assessment to delineate landslide prone areas is presented using factor analysis and fuzzy membership functions and Geographic Information Systems (GIS). A landslide inventory of 51 landslides was created in the mountainous part of Xanthi prefecture (North...
Environmental perceptions of students, farmers, and other economically active members of the local population near the protected area of Axios, Loudias and Aliakmonas estuaries, in Greece
General
This study concerns a protected area in northern Greece and examines how local people’s occupation influences their perception of environmental impacts and their views and information about the area. The target groups were local residents that (a) were employed in the primary sector, (b) were...
Performance evaluation of artificial neural networks in estimating reference evapotranspiration with minimal meteorological data
General
Detailed meteorological data required for the equation of FAO-56 Penman-Monteith (P-M) method that was adopted by Food and Agriculture Organization (FAO) as a standard method in estimating reference evapotranspiration (ETo) are not often available, especially in developing countries. The Hargreaves...
Hybrid solar - biomass plants for power generation; technical and economic assessment
General
Environmental, economic and strategic reasons are behind the rapid impulse in the deployment of renewable energy sources that is taking place around the world. In addition to overcoming economic and commercial barriers, meeting the ambitious objectives set by most countries in this field will...
Polybrominated diphenyl ethers in humans - sources and exposure
General
Polybrominated diphenyl ethers (PBDEs) are a class of widely used flame retardants that are incorporated into a wide range of consumer products such as household appliances, plastics, textiles and computers, to prevent fire. They were first introduced in the environment in the 1970s and their...
Assessment of biosolids in earthworm choice tests with different species and soils
General
Earthworm avoidance response is a new tool for rapid and efficient screening of potentially toxic substances added to soil environments. This technique was used to determine if five common, ecologically different earthworm species (Allolobophora chlorotica, Aporrectodea longa, Aporrectodea...
Application of phosphate water and slime in agriculture: investigation of the mobility of the pollutants using hydrologic modeling
General
The use of phosphate slime or phosphate water in a Mediterranean region (Gafsa, Tunisia) was investigated through hydrologic modeling. The simulations were made using the Hydrus 1D software package for a typical soil in the area of Gafsa (Tunisia). Two main applications were examined: mixing the...
Foaming control in activated sludge treatment plants by coagulants addition
General
This paper presents the results of an investigation that aimed to evaluate the efficiency of various inorganic coagulants and organic polymers to combat filamentous foaming and bulking problems, caused by the proliferation of M. parvicella and/or Gordona amarae. The duration of the investigation...
