MinE is required for the dynamic oscillation of Min proteins that restricts formation of the cytokinetic septum to the midpoint of the cell in gram negative bacteria. Critical for this oscillation is MinD-binding by MinE to stimulate MinD ATP hydrolysis, a function that had been assigned to the first ∼30 residues in MinE. Previous models based on the structure of an autonomously folded dimeric ...

Coal mine generated open pit lakes are well distributed in Raniganj coal field area, West Bengal, India. This paper screened out ecological state macrophyte index (ESMI), water quality (WQI) and multivariate statistical methods to assess the status of four lakes, Nagrakonda, Joyalbhanga, Dalurbandh, Kumardihi. Seven parameters (pH, total dissolved solids, oxygen, Secchi depth nitrate, chloride,...

than any of the other grass mixtures when collected in the cured stage. Since aphosphorosis did not occur during the winter blood sampling period, phosphorus accumulated during the growing period on winter and alpine ranges may influence blood phosphorus during the winter when forage phosphorus is in short supply. At this time it is not known to what degree a free-ranging animal can accumulate ...

Investigating uranium migration mechanisms related to the weathering of waste rocks is essential for developing strategies that can address potential environmental issues caused by mining. This work based on samples containing 2 L ferrihydrite, lepidocrocite and goethite collected in technosols from granitic rock piles, mine drainage conduits waters. The results show important role iron oxyhydr...

BACKGROUND Crystalline silica and asbestos are common minerals that occur throughout South Africa, exposure to either causes respiratory disease. Most studies on silicosis in South Africa have been cross-sectional and long-term trends have not been reported. Although much research has been conducted on the health effects of silica dust and asbestos fibre in the gold-mining and asbestos-mining s...

There are a large number of sensors to detect information in mine environment system, which provides the original data for the prevention and treatment of mine accidents. According to data flow of data acquisition, data transmission, data storage and data processing, this paper used CC2530 to design the wireless sensor nodes, analyzed the Zigbee network topology and designed an optimized PEGASI...

Mine fill is the material placed underground to fill the voids created by mining excavations. It provides overall large scale ground stabilization while allowing localized pillar recovery. In addition to providing a working floor or back, mine fill has the potential to reduce subsidence and minimize dilution. Mine fill is essential to cut and fill, benching and sublevel stoping mining methods. ...

Mining of association rules is one of the most adopted techniques for data mining in the most widespread application domains. A great deal of work has been carried out in the last years on the development of efficient algorithms for association rules extraction. Indeed, this problem is a computationally difficult task, known as NP-hard (Calders, 2004), which has been augmented by the fact that ...

Major proposed changes in drainage control from a large underground mine pool required a detailed assessment of the hydrology, geochemistry, and impacts on the receiving streams. Proposed changes entail relocation of the withdrawal and treatment facilities to an adjoining, but separate watershed and increasing the pumping rate by 35%. Fifteen major and numerous smaller mines in two coal seams c...
