Environmental flow protections are crucial to the conservation of freshwater biodiversity in dam-regulated river systems. Nevertheless, the implementation of environmental flows has lagged far behind the pace of river ecosystem alteration. The vast number of dams now in operation and the substantial resources required to modify their operations suggest that a systematic approach is needed to id...

Water conservation represents a typical green behavior and sustainable lifestyle. Understanding residents’ water behaviors is prerequisite for promoting more savers. Using the snowball sampling technique, this study conducted survey on sample of 532 Chinese residents to investigate their behavior, i.e., reusing in daily life. This aims examining psychological knowledge factors China using binar...

Objective: The aim of this study is to provide a management plan for the Sykan watershed of Darre shahr city located in Ilam province using GIS in land use planning. Methods: For land using of Sykan watershed of Ilam province with about 9 hectares area, map of classes, elevation, percent slope, geographical aspects, soil characteristics, vegetation density and the final map units were combined ...

This talk consists of two parts. In the first, the present experimental bounds on the anomalous couplings of the gauge bosons, based mainly on the LEP and Tevatron experiments, are reviewed. In the second part, the theorem of helicity conservation (HC) is presented, which should be valid in either the Standard Model (SM) or MSSM, for any two-body process at high energies and fixed angles. The e...

The precautionary principle was included in 1992 in the Rio Declaration on Environmental and Development and is a part of important international agreements and documents, for example, the Convention on Biological Diversity. Yet the interpretation of this principle is not straightforward as a guide for environmental policy – a variety of interpretations are possible. This paper identifies and e...

Nowhere in the eastern United States is the con ̄ict between the conservation of the rich biological diversity of existing forested landscapes vs. a continued expansion of suburban/exurban development more evident than in the case of Sterling Forest, a 7245 ha tract of land on the New York±New Jersey border. This paper reports on our application of geographic information systems (GIS)-based asse...
