The evaluation of changes in permeability and chemical composition of Gypseous soils through leaching in southern Mashhad
due to the solubility of gypsum, the current study is an effort to determine hydraulic and chemical properties of the soluble soils of the area and their changes throughout the leaching process. Seven soil samples with different gypsum contents were...
WETTING CHALLENGES ON THE GYPSIFEROUS SOILS
% of the total Iraq\\\\\\'s area. The present work condenses on the effect of soaking and leaching progresses on the soil stability in the saturated and unsaturated conditions...
Efficient Routing Protocol Algorithm for Wireless Sensor Networks
These Recently, different applications of wireless sensor networks in the industry fields using different data transfer protocols has been developed. As the power of sensor nodes is limited, prolonging network lifetime in ...
تاثیرات زیست محیطی کروم (Cr) موجود در افیولیت ها و معادن کرومیتی گرماب – آبدارو (شمال شرق تربت حیدریه) بر منابع آب و خاک منطقه
بررسی مهاجرت و جابجایی کروم در پساب های معدنی منطقه گرماب - آبدارو نشان داد که در این پساب ها، غلظت بالایی از کروم وجود دارد و حتی چندین منبع آبی منطقه در حد آب آلوده تشخیص داده شد که از نظر کروم مقادیر بالاتری از حد ...
EFFECT OF MECHANICAL ACTIVATION ON THE KINETICS OF LEACHINGOFCHALCOPYRITE IN THE FERRIC SULFATE MEDIA
has been investigated. It has been shown that the mechanism of leaching reaction is diffusion through the product layer
and does not undergo any change as a result of mechanical activation in a wide range of experimental conditions.
Leaching...
