Coal mine underground reservoir water storage technology is an effective technical way to achieve high efficiency of coal mining and protection resources. The stability pillar dam plays a decisive role in the safe stable operation reservoirs. Mining adjacent working faces long-term erosion are main influencing factors dam. In this paper, fluid-solid coupling calculation model for deformation ev...

This article presents the geomorphological mapping of Kalamas river delta in Thesprotia (Epirus, north-western Greece). The (also known as Thyamis) is one three main deltas this region. Detailed was performed through analysis field surveys and interpretation old maps, satellite images, aerial photos, DEM. evolution well its current morphology derives from complex interactions between alluvial, ...

Habitat fragmentation is the primary cause of the loss of biodiversity and ecosystem services, but its underlying processes and mechanisms remain poorly understood. Studies of islands and insular terrestrial habitats are essential for improving our understanding of habitat fragmentation. We argue that the Three-Gorges Dam, the largest that humans have ever created, presents a unique grand-scale...

Glass fiber is a kind of polymer, which can effectively improve the mechanical properties sand. However, improvement effect glass fibers with reticular structure different from that ordinary fibers. At same time, sandy soil diversified and part layered, such as lenticle in tailings dam, often forms layered nearby The existence has adverse effects on stability dam. In order to study reinforcemen...

The restorative potential of dam removal on ecosystem function depends on the reversibility of dam effects and its operations. While dam removal is an established engineering practice, the need for an understanding of the ecological response remains. We used paleoflood hydrology, hydrologic modeling, and aerial photo interpretation to investigate the long-term ecologic responses to dam failure ...

DNA adenine methyltransferase (Dam) plays an important role in physiological processes of Gram-negative bacteria such as mismatch repair and replication. In addition, Dam regulates the expression of virulence genes in various species. The authors cloned the dam gene of Yersinia enterocolitica and showed that Dam is essential for viability. Dam overproduction in Y. enterocolitica resulted in an ...

We introduce a new class of edge labelings for locally finite lattices which we call SB-labelings. We prove for finite lattices which admit an SB-labeling that each open interval has the homotopy type of a ball or of a sphere of some dimension. Natural examples include the weak order, the Tamari lattice, and the finite distributive lattices.

Four streams-Clear Fork, Lost Creek, Camp Creek and Still Creek-in northwestern Oregon's Sandy River Basin were monitored for temperature, dissolved oxygen levels, and fecal bacterial concentrations in a multi-year analysis examining stream health for recreational users and anchor habitat for Pacific Salmon. Temperatures were recorded using micro -T temperature loggers at 15 locations, during 2...
