Based on smooth particle hydrodynamics (SPH) method, this paper carried out the numerical simulation of ultra-high-pressure water jet (UHP-WJ) impacting steel fiber reinforced concrete (SFRC), verified established model by UHP-WJ SFRC and computed tomography (CT) scanning experiments, explored breaking mechanism damage evolution rule impacted UHP-WJ. Results indicate that in weak effect zone fi...

Minerals, fluid inclusions and stable isotopes have been studied in ultrahigh-pressure (UHP) OH-rich topaz^kyanite quartzites from Hushan (west of Dongai), in southern Sulu (China). The quartzites underwent a metamorphic evolution characterized by a peak stage (3 5 GPa and 730^8208C) with the anhydrous assemblage coesiteþ kyanite I, followed by an early near-isothermal decompression stage (2 9 ...

BACKGROUND Tuberculosis (TB) surveillance systems have some pitfalls outside of a National Tuberculosis Program and lack of efficient surveillance hampers accurate epidemiological quantification of TB burden.In the present study we assessed the quality of surveillance at the University Hospital in Pisa (UHP), Italy, and TB incidence rates over a ten year period (1999-2008). METHODS Assessment...

The composition of continental subduction-zone fluids varies dramatically from dilute aqueous solutions at subsolidus conditions to hydrous silicate melts at supersolidus conditions, with variable concentrations of fluid-mobile incompatible trace elements. At ultrahigh-pressure (UHP) metamorphic conditions, supercritical fluids may occur with variable compositions. The water component of these ...

The (Ca + , Mg 2+ ) ATPase activity, the membrane fluidity, the total phospholipid contents and the individual phospholipids, phophatidylcholine (PC), lysophosphatidylcholine (LPC), phosphatidylethanolamine (PE), phosphotidylinositol (PI) and sphingomyelin (SM) were determined in red blood cell membranes of 54 patients with essential hypertension (31 treated, THP, and 14 untreated, UHP) and com...

Metasedimentary rocks, a major component of the continental crust, are abundant within ultra-high pressure (UHP) metamorphic terranes related to continental collisions. The presence of diamond, coesite, and relics of decompressed minerals in these rocks suggests that they were subducted to a depth of more than 150–250 km. Reconnaissance experiments at 9–12 GPa and 1000–1300 C on compositions co...

In this paper a method to make inputting electrical model upon factors that affect melting process of high ultra power(UHP) electric furnace by using fuzzy rule and regression model is suggested and its effectiveness is verified with simulation experiment.

Presence of a hydroxyl group at the C-3 position in guaianolides and at the C-5 position in alantolides has been established in biologically active compounds that act as plant-growth regulators. Sesquiterpene lactones like dehydrocostus lactone and isoalantolactone were subjected to allylic oxidations with selenium dioxide (SeO2) in combination with urea hydrogen peroxide (UHP) replacing the co...

Among the techniques used to retrofit existing reinforced concrete structures, methods involving Ultra High Performance Fiber Reinforced Cementitious Composites (UHP-FRCC) are widely regarded. However, current practices make use of this material for in-situ application expensive and complicated perform. Accordingly, a new method strengthen beams by applying precast UHP-FRCC layer on bottom side...

Intracellular signal transfer in bacteria is dominated by phosphoryl transfer between conserved transmitter and receiver domains in regulatory proteins of so-called two-component systems. Escherichia coli contains 30 such systems, which allow it to modulate gene expression, enzyme activity and the direction of flagellar rotation. The authors have investigated whether, and to what extent, these ...
