Coliphages T1 and T7 of Escherichia coli were absorbed by kaolinite (K) and montmorillonite (M). Maximum adsorption of T7 (96%) to M was greater than that of T1 (84%), but the adsorption of both coliphages to K was the same (99%). Positively charged sites (i.e., anion exchange sites) on the clays appeared to be primarily responsible for the adsorption of T1 to K but only partially responsible f...

High intestinal sodium absorption is one mechanism of hypertension and constipation. The sodium-proton-exchanger subtype 3 (NHE3) is an important mediator of sodium absorption in the gut. SAR218034 (SAR) is an orally nonabsorbable specific NHE3 inhibitor. The effect of SAR (1 mg/kg per day in chow) on feces sodium excretion, systolic blood pressure via tail cuff, and gene expression of NHE3 in ...

This study, based on circular economy principles and sustainable development practices, aims to present the results of soil samples analysis after their mixture with a biobed bio-mixture straw, compost, used for two consecutive years as organic bio-filter olive oil mill wastewater. So far, exhausted bio-mixtures in biobeds minimize pesticide point-source contamination turned out contain residue...

in this research, the groundwater quality of abhar plain was studied for drinking, domestic and irrigation uses. to assess the evaluation of hydrochemistry and quality, 26 groundwater samples were collected and analyzed for the physicochemical factors such as ph, electric conductivity (ec), total dissolved solids (tds), total hardness (th), na+, k+, ca2+,mg2+, cl-, so42-, hco3-, co32- during oc...

Polyacrylonitrile-co-sodium methallylsulfonate copolymer (AN69) and polysulfone (PSf) synthetic membranes were prepared and used for the removal of methylene blue (MB) from water. Atomic Force Microscopy (AFM), Ionic exchange capacity (IEC), and Swelling ratio (Sr) were employed to determine the membrane characteristics. pH, membrane composition and initial dye concentration were used for t...

The (13)C- and (1)H- NMR spectra of isopropyl N-dodecanoylsarcosinate (SLIP) were measured in CDCl(3), CD(3)OD and in sodium dodecanoylsarcosinate (Sar) aqueous solution. The existence of both cis and trans isomeric forms are observed for SLIP just as for Sar. The trans/cis ratio of SLIP in a dilute CDCl(3) solution is over 3.2, which is indicating that SLIP-trans conformation is more stable in...

The PVL springs are used for both domestic and agricultural purposes. seepage from the has resulted in producing a large expanse of wetlands is therefore intensively use dry season farming. aim this study was to determine hydrogeological, hydrochemical characteristics, origin their suitability irrigation. hydrogeology determined by field mapping. physico-chemical parameters were laboratory meth...

Groundwater in the Touggourt region—or as its named, Oued Righ—in southeastern Algeria, is only source of irrigation. To assess suitability for agricultural purposes, we collected 72 samples from wells at this region, physical and chemical measurements were carried out each water sample, calculations sodium adsorption ratio (SAR), permeability index (PI), soluble percent (SSP), residual carbona...

The assessment of the suitability and status irrigation water quality from aspect its potential negative impact on soil salinization mapping spatial distribution within area three Morava rivers, which includes South, West, Great basins, was purpose this research. A total 215 samples were tested, their evaluated based analysis following parameters: pH, electrical conductivity (EC), dissolved sal...

     It is widely known that the development of gullies causes the loss of a great amount of soil and can be considered as one of the principal causes of geo-environmental degradation. The study area of the present research is located in the eastern shores of Urmia Lake. This study sought to evaluate the rate of growth and effective factors on the area’s gully dynamic over a year. To achieve th...
