The incorporation of sodium and aluminium in magnesium silicate hydrate phases (M-S-H), possible binding cement, was investigated. Magnesium alumino containing (M-A-S-H N samples) were synthesized batch experiments with NaNO3 ~ 100 mmol/L at Mg/Si ratios equal to 0.8 1.2, Al/Si 0, 0.1 0.2, equilibrated 20 50 °C. Thermogravimetric analysis (TGA), X-rays diffraction (XRD), 29Si MAS NMR data showe...

the effects of an azotobacter chrococum isolate (strain ag11) and vermicompost and their combined effects on a rain-fed winter wheat (var. zagros) nutrient uptake and growth and soil water content were investigated with a farm trial.  the dry matter yield was determined in 5 occasions. gravimetric soil water content, soil microbial respiration and the number of azotobacter were determined at sa...

The p-Si/n-MgZnO:Er/Ga2O3/ZnO:In diodes with different Ga2O3 thicknesses were fabricated through spray pyrolysis deposition at 450 °C aqueous solutions containing magnesium nitrate, zinc acetate, erbium gallium and indium nitrate precursors. effects of layer thickness on the diode properties investigated. For deposited films, a combined tiny hexagonal slices small blocks surface morphology was ...

The study examined the water supply situation in Abeokuta, with emphasis on quality of distributed by Ogun State Water Corporation from treatment plant Abeokuta Scheme. samples were collected standpipes (taps) across city randomly selected using stratified random sampling method and was analysed for physical chemical parameters: pH, total dissolved solids (TDS), electrical conductivity (EC), al...

Abstract The present study aims to develop an efficient predictive model for groundwater contamination using Multivariate Logistic Regression (MLR) and Random Forest (RF) algorithms. Contamination by ammonia is recorded many authors at Sohag Governorate, Egypt attributed urban growth, agricultural, industrial activities. Thirty-two samples representing the Quaternary aquifer are collected analy...

This study is used the water quality index (WQI), which generated by combining several parameters. gives a helpful representation of overall for public and all intended applications, it demonstrates that pollution beneficial in management decision-making. The Euphrates River was assessed order to determine drinking water. using WQI, includes ten physicochemical criteria. achieved submitting com...

low water-wettability and oxidation resistance of graphite have limited its application in carbon containing refractory castables. the aims of this study were improvement of water-wettability and the oxidation resistance of natural flaky graphite by applying an oxide coating on its surface. to develop the coating, magnesium aluminate spinel sol was formulated via a citrate-nitrate route and gra...

Water quality is the most critical factor affecting fish health and performance in aquaculture production systems. Fish life mostly dependent on water fishes live for all their needs. Therefore, it essential to have a clear understanding of requirements fish. This research discusses parameters (temperature, pH, nitrate, phosphate, calcium, magnesium, dissolved oxygen (DO)) fisheries reviews exi...

Groundwater is prime and major source of drinking water in our world. Jharkhand also used for drinking, domestic, irrigation, mining industrial etc. purposes. In some population are suffering from scarcity pure have partial facility with as groundwater many area contaminated fluoride, arsenic, heavy metals iron dangerous chemicals. This review paper focuses on current status contamination diffe...

Rajasthan's Bikaner District, part of the Thar Desert, is experiencing problems with falling groundwater levels, high salinity, fluoride and nitrate concentrations. Therefore, quality studies are underway to determine suitability for drinking purposes in district. Quality analysis performed using parameters such as Conductivity (EC), Total Dissolved Solids (TDS), pH, Calcium, Potassium, Sodium,...
