M. Łucarz, AGH University of Science of Technology, Engineering of Faculty Foundry, Kraków, Poland The paper presents the results of the research on the used moulding sands subjected to mechanical and thermal reclamation at different stages of the process in the foundry. The research on thermal treatment was carried out in an experimental thermal reclamation appliance. The effects of the proces...

The reclamation and reuse of wastewater is one of the possible ways to relieve the serious fresh water resource crisis in China. Efficient reclamation treatment technologies ensure the safe reuse of reclaimed water. In order to screen out and evaluate technologies appropriate for reclamation treatment, a great deal of efforts have been brought to bear. In the present study, a toxicity-based met...

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...

Coal mining activities in Indonesia have a negative impact on the environment. Some vegetations are disturbed even be lost especially with open mine operation. Revegetation is one of that can improve quality post land, which also included land reclamation activities. The purpose this study to analyze biodiversity flora post-coal revegetation area and compare condition vegetation various age cla...

Understanding the interactions among soil microbial species and how they respond to land reclamation is essential evaluate success of ecological restoration actions in disturbed mine soil. In this study, we strived reveal bacterial communities along timeline a coal Zoucheng, China. To do so, investigated changes composition over time constructed molecular networks (i.e., network) following mini...

This article concerns the issue of appearance and growth invasive plant species in land degraded by hard coal mining repercussions this process, particularly context reclamation. These species, such as Canadian goldenrod or Japanese knotweed, which nearly always form extensive monocultural patches vegetation, contribute to displacement both native those introduced part biological restoration. I...
