optimization of drilling fluid parameters such as mud weight, salt concentration, and temperature is essential to alleviate instability problems during drilling through shale sections. the selection of suitable mud parameters can benefit from analyses that consider significant instability processes involved in shale-drilling–fluid interactions. this paper describes the development of analytical...

Temperature and hydrostatic pressure are essential in determining the assemblage of species in their specific biotopes. To evaluate the effect of high pressure on the range of viability of thermophiles, the pressure and temperature dependence of the growth of the methanogenic archaebacterium Methanococcus thermolithotrophicus was investigated. High pressure up to 50 MPa enhanced the growth rate...

482 www.thelancet.com Vol 382 August 10, 2013 Sustained lowering of blood pressure by 10 mm Hg systolic and 5 mm Hg diastolic lessens the risk of recurrent stroke by about one-third (relative risk 0·66, 95% CI 0·56–0·79). Larger reductions in blood pressure are associated with greater reductions in risk. This eff ect is consistent in most subtypes of stroke because hypertension-induced intracra...

[email protected] _________________________ I n 1993, 1450 coronary interventions were performed in the Catharina Hospital in Eindhoven, the Netherlands. At that time, due to financial restraints, stents were not available. After two years of follow up, the reintervention r...

Optimisation provides the means of raising or lowering the target suction pressure in a Honeywell Genus® pack controller. Suction pressure optimisation means that suction pressures are raised to the highest level allowed within defined evaporator performance limits. This provides optimum compressor energy consumption while ensuring that the refrigerated merchandise quality is maintained at the ...
