the electro discharge machining (edm), one of the methods used in the machining industry and a non-traditional manufacturing method, the electro erosion process does not depend on the hardness of material and offers a way to process materials of very complex geometry with very fine and high precision by using cheap electrode materials, which make it a preferred method. in this study, effect of ...

NJWRRI has funded research on topics ranging from pollutants in ground and surface waters to the behavior of estuarine fish to the ecology of wetlands. With funds provided by Congress and Rutgers University, the NJ Water Resources Research Institute supports a program of research each year which addresses a periodically-updated list of priority issues developed by the Advisory Council in consul...

Environmental transitions often result in resource mixtures that overcome limitations to microbial metabolism, resulting in biogeochemical hotspots and moments. Riverine systems, where groundwater mixes with surface water (the hyporheic zone), are spatially complex and temporally dynamic, making development of predictive models challenging. Spatial and temporal variations in hyporheic zone micr...

The South East of Ireland (County Carlow) contains a deposit of the valuable lithium-bearing mineral spodumene (LiAl(SiO₃)₂). This resource has recently attracted interest and abstractive mining in the area is a possibility for the future. The open cast mining of this resource could represent a potential hazard in the form of metalliferous pollution to local water. The population of County Carl...

Surface water is used for a variety of purposes like drinking, washing, bathing, recreation as well as numerous other varied industrial applications. The wholesomeness of these surface waters has become an issue of great concern. Water pollution is a burning issue all over the world. In recent years an increasing awareness has developed on the impact of human activities on the environment becau...

livestock grazing and rangelands fire are important ecological disturbances influencing the vegetation and soil properties in rangelands ecosystem. this study was conducted to determine the effects of different burned treatments and distances from the water sources on some soil and vegetation properties of rangelands ecosystem. the experiment was conducted in lashgar dar rangelands. vegetation ...
