In arid regions, decreased soil fertility has adversely affected agricultural sustainability. The effects of different amendments in alleviating these issues and increasing remain unclear. Herein, a two-year field experiment was conducted to evaluate the properties grey desert respiration (SR) dynamics under six treatment groups: biochar (BC), leonardite (LD), anionic polyacrylamide (PAM−), cat...

A large amount of the water diverted for irrigated agriculture seeps from earthen canals during its conveyance to fields. Besides a shortfall in availability, variety environmental and economic damages are caused by canal seepage . Polymer sealants provide an economical alternative permanent liners reducing temporarily. Field studies polymer sealant linear anionic polyacrylamide (LAPAM) conduct...

Sandy soils are prone to nutrient losses, and consequently do not have as much agricultural productivity other soils. In this study, coal fly ash (CFA) anionic polyacrylamide (PAM) granules were used a sandy soil amendment. The two additives incorporated the layer (depth of 0.2 m, slope gradient 10°) at three CFA dosages PAM dosages. Urea was applied uniformly onto low-nitrogen (N) surface prio...

Abstract A considerable amount of very fine particles can be found, e.g., stored in tailing ponds, and they include valuable or hazardous minerals that have the potential to recovered. Selective flocculation, i.e., formation larger aggregates from specific minerals, offers a promising approach improve recovery ultrafine particles. This study focuses on use new bio-based flocculation agent made ...

Industrial expansion has increased the discharge of contaminated wastewater. Wastewater can be treated by adsorption with petroleum-based hydrogels but materials are not biodegradable and therefore cause secondary toxic waste. In this work, hydrogel composites prepared based on non-biodegradable polyacrylamide cassava starch (CS) poly(vinyl alcohol). The effect CS content porous structure is st...

conclusions our successful extraction of purified lps from e. coli isolates of uti patients’ urine samples can be an important step to understand the uti disease conditions. results the silver-stained gel demonstrated both smooth and rough type lps by showing trail-like band patterns with the presence and lacking o-antigen region, respectively. coomassie blue staining showed no band assuring th...

The Ekati Diamond Mine, located approximately 300 km northeast of Yellowknife in Canada's Northwest Territories, uses mechanical crushing and washing processes to extract diamonds from kimberlite ore. The processing plant's effluent contains kimberlite ore particles (< or =0.5 mm), wastewater, and two wastewater treatment polymers, a cationic polydiallydimethylammonium chloride (DADMAC) polymer...
