Soil degradation and pollution is one of the main problems threatening sustainable development agriculture. This study used remote sensing geographic information system (GIS) techniques to assess risks soil heavy metals in some soils north Nile Delta. The area suffers from salinity, alkalinity, water logging, so a spatial model was used. Relying on landsat ETM+ images digital elevation (DEM), i...

This research investigates the effect of fiber pre-treatment on mechanical and physical properties unidirectional water hyacinth (WH) reinforced epoxy resin composites. The fibers have been produced by processing. 50–70 cm length WH stems are brushed with an iron brush to mechanically extract strands. dry then were pre-treated alkalization esterification. ha ve conducted immersing 2 %, 5 % 10 N...

Soil physicochemical properties are the main driving factors affecting stability and diversity of soil microbial community. The impacts saline–alkali situation associated degradation need to be understood reversed as communities increasingly affected by saline–alkaline soil. However, differences between salinization alkalization their impact on microbiota have been overlooked. object this study...

Hybrid anion exchange membranes (AEMs) were prepared via chemically functionalizing and crosslinking poly(styrene-b-[ethylene-co-butylene]-b-styrene) (SEBS) copolymers low molecular weight homo-polystyrene (hPS). Via sequential chloromethylation, crosslinking, quaternization, alkalization, a series of hPS/SEBS AEMs obtained with varying content hPS. Systematic structural, morphological, mechani...

Abstract Purpose Root growth, respiration, water uptake as well root exudation induce biogeochemical patterns in the rhizosphere that can change dynamically over time. Our aim is to develop a method provides complementary information on 3D system architecture and gradients around roots needed for quantitative description of processes. Methods We captured first time maize plants grown rectangula...
