the soil particles and aggregates. Dispersion or flocculation of clays occurs because of the repulsion of similar Reclamation of sodic soils is imperative in many areas where detericharged clay platelets and the ability of the soil solution oration of land and water resources is in progress. While the chemical mechanisms involved in the reclamation of sodic soils are well deto mitigate this rep...

Achieving high performance for concurrent applications on modern multiprocessors remains challenging. Many programmers avoid locking to improve performance, while others replace locks with non-blocking synchronization to protect against deadlock, priority inversion, and convoying. In both cases, dynamic data structures that avoid locking require a memory reclamation scheme that reclaims element...

Abstract: To evaluate the damage of land affected by disturbances in the course of construction. In 2011 our government abolished the regulations of land reclamation implemented in 1988 and introduced new regulations for land reclamation. The single-appropriate suitability evaluation of the new regulation has two influences: first, it offers the land oblige an opportunity that could legally pur...

The typical problems caused by Mining Subsidence and mining pollution made by coaling, made the Mine Subsidence reclamation and retorting the integrated mining environment necessary. Then, we create effective management measures of “full investigation, scientific planning, focused, sound institutions, the establishment of the system” and create the advanced technology of “mud pump reclamation, ...

Memory management is a critical component in almost all shared-memory, concurrent data structures and algorithms, consisting in the efficient allocation and the subsequent reclamation of shared memory resources. This paper contributes a new, lock-free, amortized constant-time memory reclamation scheme called Stamp-it, and compares it to five well-known, selectively efficient schemes from the li...

The primary goal of this study was to isolate hydrocarbon-degrading organisms and assess their ability to bioremediate petroleum-contaminated soil and water. Nigeria is one of the major oil producing countries and petroleum contamination is widespread in agricultural soil. Alcaligenes sp. strain 3k was isolated from a kerosene-polluted soil in Ilorin, Nigeria. We also assessed its ability to de...

Oil sands mining in northern Alberta impacts a large footprint, but the industry is committed to reclaim all disturbed land to an ecologically healthy state in response to environmental regulations. However, these newly reconstructed landscapes may be limited by several factors that include low soil nutrient levels and reduced microbial activity. Rhizosphere microorganisms colonize plant roots ...

understanding the relationship between soil and plant is essential for reclamation of degraded lands. in order to investigate the relationship between atriplex halimus density with carbon sequestration the rangeland of incheborun was studied. soil samples were collected randomly by auger in the depth of 0-30 cm of the soil profile in three different plant densities (400 stand per hectare) with ...

Soil salinization is a major problem affecting soils and threatening agricultural sustainability in arid semi-arid regions, which makes it necessary to establish an efficient strategy manage soil salinity confront economic challenges that arise from it. Saline recovery involving drainage of shallow saline groundwater the removal salts by natural rainfall or irrigation are good strategies for re...

A major environmental concern due to dispersal of industrial and urban wastes generated by human activities is the contamination of soil. The release of heavy metals into the terrestrial ecosystem is a major problem. Accumulation of heavy metals in environment and particularly in soil is a serious environmental concern, as the accumulated heavy metal ions can find their way into living organism...
