Abstract The present study focused on evaluating the groundwater hydrogeochemical of shallow aquifers in semi-arid areas northern Ethiopia, using geospatial modelling and multivariate statistical techniques. Physico-chemical parameters, including pH, major ions, electrical conductivity (EC), total dissolved solids (TDS), hardness (TH), pollution index (PI) other from 22 samples have been used t...

Subsurface-tile drainage is designed to remove gravitational water and soluble salts from the soil-root zone. However, soil swelling, as influenced by soil Na and electrical conductivity (EC), will reduce saturated hydraulic conductivity. The objective of this research was to determine the influence of Na and EC on the amount of water retained at field capacity (33 kPa), in northern Great Plain...

Although barley (Hordeum vulgare L.) is regarded as salt tolerant among crop plants, its growth and plant development is severely affected by ionic and osmotic stresses in salt-affected soils. To elucidate the tolerance mechanism, growth and ion uptake of three barley cultivars, differing in salt tolerance, were examined under different levels of NaCl, K/Na and NaHCO3 in the root medium. The cu...

The nature of the energy requirement for irreversible adsorption of phages T1 and phi80 was studied by using various specific energy inhibitors and mutants lacking either the Ca2+, Mg2+-adenosine triphosphatase or the ability to produce cytochromes in the absence of added 5-aminolaevulinic acid. It was found that irreversible adsorption could be energized both through the electron transport cha...

dry land salinity is one of the major problems affecting agricultural products. the main consequences of plant exposure to salt stress are water deficit and ion excess, which lead to several morphological and physiological changes. in order to evaluate the effect of salinity on some physiological characteristics of 8 spring rapeseed cultivars, an experiment was conducted in the greenhouse at ya...

The synthesis of Mg3(NDC)3(DEF)4 (NDC = 2,6-naphthalenedicarboxylate, DEF = N,N-diethylformamide, 1), the first porous metal-organic framework solid incorporating Mg2+ ions, is reported. Its structure consists of linear Mg3 units linked via NDC bridges to form a three-dimensional framework, featuring one-dimensional channels filled with DEF molecules. Significantly, its framework is fully analo...

Abstract In granitic regions, water salinity typically ranges from 30 to 40 mg L −1 at the surface and 300 500 for groundwater. Technogenic activity in Oaxaca has altered concentration chemical composition, which explains occurrence of salinization processes contamination natural waters. To determine physical–chemical composition Atoyac-Verde river, fifty-two samples were collected tributaries ...
