It is long known that the Fokker-Planck equation with prescribed constant coefficients of diffusion and linear friction describes the ensemble average of the stochastic evolutions in velocity space of a Brownian test particle immersed in a heat bath of fixed temperature. Apparently, it is not so well known that the same partial differential equation, but now with constant coefficients which are...

in some islamic narrations (ahadith) it is prohibited to postpone the performance of had (prescribed punishment). by analyzing the content of these narrations, this article concludes that they are not specifically related to hodoud in its idiomatic sense, i.e. prescribed punishments as opposed to ta’zir(discretionary punishment). indeed all punishments must be certain and performed in a reasona...

By molecular dynamics simulations, the boundary condition for the Boltzmann equation at a vapor-liquid interface is found to be the product of three one-dimensional Maxwellian distributions for the three velocity components of vapor molecules and a factor including a well-defined condensation coefficient. The Maxwellian distribution for the velocity component normal to the interface is characte...

This paper propose a relatively simple adaptive control (in the presence of input constraints) for a class of nonlinear distributed parameter models with application to a nonisothermal exothermic chemical tubular reactor with axial dispersion. Our objective is to regulate the reaction temperature in a prespecified neighborhood of a given reference temperature. we apply a λ-tracking controller, ...

Abstract-A numerical solution for the free convection flow past a vertical semi-infinite flat plate embedded in a highly saturated porous medium by allowing the plate to have a non-uniform temperature or a non-uniform heat flux distributions has been developed. Both local heat transfer rate and excess surface temperature as a function of the distance along the plate are tabulated for a few case...

The coolant temperature of internal combustion engines can be regulated effectively by advanced thermal management systems that feature multiple computer controlled servomotor actuators (i.e., a variable position smart valve, variable speed electric water pump, variable speed electric radiator fan). When the components of the advanced thermal management system function harmoniously, desired the...

OBJECTIVE The aim of this study was to identify the challenges faced by primary care physicians (PCPs) when prescribing medications for patients with chronic diseases in a teaching hospital in Malaysia. DESIGN/SETTING 3 focus group discussions were conducted between July and August 2012 in a teaching primary care clinic in Malaysia. A topic guide was used to facilitate the discussions which w...

OBJECTIVE To evaluate studies of pharmacist-led interventions on potentially inappropriate prescribing among community-dwelling older adults receiving primary care to identify the components of a successful intervention. DATA SOURCES An electronic search of the literature was conducted using the following databases from inception to December 2015: PubMed, Embase, Cumulative Index to Nursing a...

BACKGROUND Licensing arrangements for nicotine replacement therapy (NRT) in the UK were broadened in 2005 to allow prescribing to pregnant smokers. However, estimates of NRT prescribing in pregnant females in the UK are currently lacking. AIM To assess trends in NRT prescribing around pregnancy, and variation in prescribing by maternal characteristics. DESIGN AND SETTING Population-based de...

Concern has been raised about inadequate pharmacology teaching in medical schools and the high incidence of prescribing errors by doctors in training. Modifications in pharmacology teaching have been carried out in many countries. The present study was carried out using a semi-structured questionnaire to obtain students' perceptions of their knowledge, attitudes, and skills with regard to diffe...
