چکیده

The problems related to groundwater contamination by iron and fluoride is common and serious all over the world, especially in developing countries. Excess amounts of these contaminants have created health problems. For this reason, the maximum permissible limit for iron given by WHO and BIS is 1 mg/l, however 0.3 mg/l is the desirable limit. For fluoride, the desirable limit as per WHO is 0.5-1 mg/l. While as per EPA and PHS the optimal levels of Iron and Fluoride in drinking water is 0.3 mg/l and 0.7 mg/l respectively. In this study, an effort has been made to remove iron and fluoride from groundwater using the process of adsorption. The experiments were performed on various parameters like dosage of adsorbent, pH, temperature and contact time to check their influence on adsorption. Adsorbent dosage of 4.7 g/50 ml at pH 5, temperature of 20oC and contact time of 420 minutes were considered as optimum.

This paper describes the cross-talk analysis of high-speed PCB design. Some models using multiple PCB traces above a ground plane having guard traces and vias are taken and the results are obtained from modeling and simulation using Ansoft HFSS software tool and are compared with the experimental results. Reduction techniques of crosstalk are highlighted.

A Parallel multiplier using approximate compressors are proposed in this paper. The two new approximate 4-2 compressors are proposes that the simplified compressors have better power consumption than the optimized 4-2 compressor existing designs. These approximate compressors are then used in the restoration module of a Parallel multiplier. Four different schemes for utilizing the proposed appr...

several edge recognition strategies have now been planned within the past decades. Many are derived from differential strategies such as for example Sobel, Roberts, Laplacian operators, and therefore on. Nevertheless these calculations are quite sensitive to sound, in order to restrain sound before sensing edges. In this report intensive literature review has been presented in numerous edge rec...
