an accurate design of drip irrigation requires water quality analysis that helps attain a better emission uniformity coefficient. this study examined aquifer qualitative parameters in the north of khuzestan province to assess the applicability of groundwater in trickle irrigation systems. for this purpose, interpolation technology was used to map chemical parameters collected from 104 deep well...

ground water samples from different upazilas of sunamganj district have been analyzed for drinking and irrigation purposes. correlation coefficients among different parameters were determined. an attempt has been made to develop linear regression equations to predict the concentration of water quality constituents having significant correlation coefficients with electrical conductivity (ec). ca...

The present study was carried out to characterize leachate from waste dumping site and its impact on surrounding surface water quality at Rajbandh in Khulna. For this purpose, samples (10) (5) were taken the during two season monsoon post respectively. daytime 9 a.m. 1 p.m because midday temperature rises physico-chemical parameters of are modified. Some such as pH, Electrical conductivity (EC)...

Groundwater makes up an important part of global freshwater resources, though it is often threatened by overuse of natural resources along with abundant production of wastes in modern society. This study aims to investigate the removal of three heavy metals including nickel, cadmium, and lead from groundwater via electrocoagulation, a suitable method for treatment of water-soluble compounds, de...

the karkheh dam reservoir with a capacity of more than 5 billion cubic meter is the largest dam in iran with both agricultural and drinking usages. its hydrodynamics and water quality were modeled and simulated to analyze the total maximum daily load (tmdl) of total dissolved solids (tds). the simulation was supported with measurements of temperature and tds measurements during two years. a lat...

<p>The dumping of solid waste in uncontrolled landfills can cause significant impacts on the environment and human health. The open dumps formation leachate which contaminated groundwater; use these groundwater reported danger to goal protection is necessary control release migration pollutants from subsurface. In this paper, above-mentioned problems were dealt with case study Ariyamangal...

The THz transmission spectra of three trichloroanisole (TCA) compounds (2,3,4-TCA, 2,4,6-TCA and 2,5,6TCA) are measured using terahertz time-domain spectroscopy (THz-TDS). The spectrum of 2,4,6-TCA in the solid phase displays several discrete absorption peaks over frequency range from 0.1 to 1.5 THz, with significant peaks observed at 0.6, 0.95 and 1.2 THz. A weak absorption peak is observed ne...

Arsenic concentration of agricultural soil and surface water used for irrigation were surveyed in two abandoned mining sites Jos South Local Government Area. DB-Zang Dorowa total dissolved solid, hardness, electrical conductivity, temperature pH the determined according to standard procedure. Result indicates that Total dissolve solids W1 was 156±2.00mg/L W2 (160±2.00mg/L), hardness (35.20±4.70...

The 3.0-3.1A X-ray structures of the cytochrome b(6)f complex from Mastigocladus laminosus and Chlamydomonas reinhardtii obtained in the presence of the p-side quinone-analogue inhibitor tridecyl-stigmatellin (TDS) are very similar. A difference occurs in the p-side binding position of TDS. In C.reinhardtii, TDS binds in the ring-in mode, as previously found for stigmatellin in X-ray structures...
