The effect of dissolved water on the diffusivity of Ar in glasses and melts of rhyolitic and albitic compositions was investigated experimentally at pressures up to 1500 MPa and water contents of 0.1^5 wt%. The data for water-poor rhyolitic composition at 500 MPa can be described in the whole temperature range of 480^11023C by a simple Arrhenius relationship DAr = 2.14U1036 m2/s exp(318 883/T)....

Background: Minor physical anomalies (MPA) are unusual morphological deviations that have no serious medical or cosmetic significance to an individual. But however minor they may be, various studies across the world have revealed their significance as a possible endophenotype of schizophrenia. This study is an attempt towards understanding the various sociodemographic and illness correlates as ...

UNLABELLED Attempts have been made to improve the mechanical properties and convenience of use of glass-ionomer cement (GIC) by various modifications, in particular by including a free radical-polymerizable component ("resin-modified" GIC, RMGIC). Necessarily, the one replaces part of the other, but the chemistry suggests that the formation of each network separately would inhibit diffusion and...

The resistance to hydrogen embrittlement is of essential importance for steels for vessels for storage of hydrocarbons and depends on the effect of absorbed hydrogen on steel ductility. API tests have shown for the 490 MPa yield stress HSLA steels with the microstructure of ferrite and cementite particles a much greater reduction of area than for the 350 MPa steel with the microstructure of pol...

Medroxyprogesterone acetate (MPA) is widely known for its use in combination hormone therapy for postmenopausal women. However, MPA is also commonly used in young women for contraception and treatment of a number of gynecological conditions. Despite its widespread use, the cardiovascular effects of MPA in young women are unclear. Therefore, the purpose of this study was to determine the acute e...

OBJECTIVE To determine the prognostic significance of altered plasma viscosity and erythrocyte aggregation in unstable angina. DESIGN A prospective study of 96 consecutive patients with unstable angina allocated to one of two groups according to predefined threshold values for plasma viscosity and erythrocyte aggregation at study entry. The patients received a standardised treatment and were ...

Byssochlamys nivea is a thermal resistant filamentous fungi and potential micotoxin producer. Recent studies have verified the presence of ascospores of such microorganism in samples of pineapple nectars. Although the majority of filamentous fungi have limited heat resistance and are easily destroyed by heat, Byssochlamys nivea ascospores have shown high thermal resistance. The aim of this work...

Peak combustion pressures (PCP) are increased in heavy-duty diesel engines to obtain higher thermal efficiency. Fuel injection strategy has been a major measure improve the and emissions of engines. But most existing work multi-injection strategies was not limited by PCP or conducted under lower (∼15 MPa). In this study, an experimental study is further understanding on engine performance relat...

CONTEXT The Women's Health Initiative (WHI) trial of estrogen plus progestin vs placebo was stopped early, after a mean 5.6 years of follow-up, because the overall health risks of hormone therapy exceeded its benefits. OBJECTIVE To report health outcomes at 3 years (mean 2.4 years of follow-up) after the intervention was stopped. DESIGN, SETTING, AND PARTICIPANTS The intervention phase was ...
