Background: Many psychiatric patients have nicotine and other substance dependence. Objective: To determine the prevalence of nicotine and opium dependence among psychiatric in-patients inKerman, a city in southwesternIran. Methods: Three groups of psychiatric inpatients, chronic medical patients and a sample from local population, each including 400 subjects were selected.  Nicotine dependence...

A quantitative study involving Mainland China (the PRC), Taiwan, India, the UAE, and US, five areas with 852 responses of IT/IS personnel data towards building a more suitable Circumplex Career Anchor Model for personnel, to test research model reorganized (quadrant) anchors. The bureaucratic, protean, careerist, social four quadrant anchors, have significantly positive effect on career satisfa...

the voltammetric behaviour of sulfadoxine (sdn) was studied at a glassy carbon electrode in 0.2 m phosphate buffer solutions using cyclic, differential-pulse (dpv) and square wave voltammetry (swv). the dependence of the current on ph, concentration, and scan rate was investigated to optimize the experimental conditions for the determination of sdn. the oxidation process was shown to be diffusi...

We present a new type of pFET synapse; by degenerating the source, the oxide currents provide stabilizing feedback to the oating gate and to the drain. We present experimental measurements from a oating-gate synapse that simultaniously computes four-quadrant products of its input and weight values, and computes a four-quadrant correlation, typical of hebbian and backpropagation learning rules, ...

In recent years, flourodeoxyglucose-positron emission tomography/computed tomography (FDG PET/CT) has been used intensively in the field of oncology. However, an increase in FDG uptake has been observed both in malignant tissues, and inflammatory processes. Therefore false-positive results have appeared. We present a 70-year-old male patient who presented to the hospital with right lower quadra...

We formulate a quantitative description of backscattered linearly polarized light with an extended photon diffusion formalism taking explicitly into account the scattering anisotropy parameter g of the medium. From diffusing wave spectroscopy measurements, the characteristic depolarization length for linearly polarized light, lp , is deduced. We investigate the dependence of this length on the ...

OBJECTIVE To assess the sensitivity and specificity of ultrasonography in differentiating causes of acute right lower quadrant pain in women of child-bearing age by taking surgical outcome as the gold standard. METHODS The descriptive analytical study was conducted at PNS Shifa Hospital, Karachi, from July to December 2008, and comprised female patients of child-bearing age who presented with...
