In the process of coal resources development, a large number strip pillars have been left behind in mines central–eastern China. With increase mining depth year by year, rock burst threat is becoming more and prominent due to influence buried depth, geological structure, gob other factors. Backfilling main means recover residual pillar. order investigate effect backfilling on prevention control...

Ceramic waste is most commonly produce from ceramic industry, this waste is in the form of pest and hard form, pest waste is known as the filter waste or slurry waste, which is produced at the end of polishing and finishing of ceramic tiles. The paper discuss that ceramic slurry waste powder is replaced by cement in concrete. Concrete grade M25 was made by replacing by 0% to 30% of Ordinary Por...

Abstract Type I X-ray bursts (XRBs) are powered by thermonuclear burning on proton-rich unstable nuclides. The construction of burst models with accurate knowledge nuclear physics is required to properly interpret observations. Numerous studies that have investigated the sensitivities inputs commonly extracted strength NiCu cycle in rp process, determined 59 Cu( p , α ) 56 Ni and γ 60 Zn reacti...

OBJECTIVES The aim of this study was to evaluate two commonly used advanced bipolar devices (ENSEAL(®) G2 Tissue Sealers and LigaSure™ Blunt Tip) for compression uniformity, vessel sealing strength, and consistency in bench-top analyses. METHODS Compression analysis was performed with a foam pad/sensor apparatus inserted between closed jaws of the instruments. Average pressures (psi) were rec...

We investigated the time-dependent modulation of arterial baroreflex (ABR) control of muscle sympathetic nerve activity (MSNA) that occurs during isometric handgrip exercise (IHG). Thirteen healthy subjects performed a 3-min IHG at 30% maximal voluntary contraction, which was followed by a period of imposed postexercise muscle ischemia (PEMI). The ABR control of MSNA (burst incidence and streng...

A central prediction of much theory on adaptive radiations is that traits should evolve rapidly during the early stages of a clade's history and subsequently slowdown in rate as niches become saturated--a so-called "Early Burst." Although a common pattern in the fossil record, evidence for early bursts of trait evolution in phylogenetic comparative data has been equivocal at best. We show here ...

Custom-designed wound dressing films of chitosan and alginate have been prepared by a casting/solvent evaporation method for hydrophobic therapeutic agent encapsulation. In this parametric study, the propylene glycol (PG) and calcium chloride (CaCl2) concentrations were varied for chitosan and alginate films, respectively. Mechanical and chemical inter-related responses under observations inclu...

Ensuring the safe operation of pipe fittings in a natural gas station is critical. The irregular shape tee easily leads to uneven mechanical properties manufacturing process. strength may be lower than requirements due its unqualified heat-treatment As result, selecting reliable way repairing low-strength pipes pressing concern. To repair pipes, special-shaped epoxy steel sleeve (SSESS) was des...
