road accident severity may be influenced by a number of various systematic causal factors. the weather and road accidents have a close relationship with each other and a number of methods have been proposed for measuring the risk of a road accident with rainy, foggy, and snowy weather and high winds. recent studies indicate that road collision rates increase during precipitation. the weather wa...

A partially hydrolyzed guar gum preparation (PHGG, average molecular weight: 20,000), obtained as a water-soluble dietary fiber by digestion of guar gum with beta-D-endomannanase, was administered as a beverage (11 g a day, bid) to 15 constipated women for 3 weeks. Defecating frequency, pH, weight, moisture, and bacterial flora of the feces were investigated and compared with the control period...

The detection of higher modes of oscillation in atomic force microscopy can provide additional information on sample properties. However, the limited bandwidth of the photodiode in the beam deflection detection technique often limits the detectable frequency range. We present a novel cantilever design, which allows lowering the frequency of higher modes of oscillation, maintaining the frequency...

The goal of hyptensive anesthesia is the safe reduction of intraoperative blood loss, thus reducing transfusion risks.  Previous hypotensive technics had a narrow margin of safety in that cardiac output was usually reduced in proportion to the degree of induced hypotension. This is in contrast to the results of our study, in which Sodium Nitroprusside was used as the sole hypotensive agent. Ni...

OBJECTIVE The aim of the present study was investigate the association between six genetic variants in the nuclear receptor genes PPARA, RXRA, NR1I2 and NR1I3 and the lipid-lowering efficacy and safety of statin therapy. SUBJECTS AND METHODS The study was carried out on 240 Brazilian hypercholesterolemic patients on simvastatin and atorvastatin therapy. The polymorphisms were analyzed by PCR-...

The achievement of a good glycaemic control is one of the cornerstones for preventing and delaying progression of microvascular and macrovascular complications in patients with both diabetes and chronic kidney disease (CKD). As for other drugs, the presence of an impaired renal function may significantly affect pharmacokinetics of the majority of glucose-lowering agents, thus exposing diabetic ...

Talk Abstract We examine the solution of high-frequency Helmholtz equations using 2nd, 4th and 6th order finite difference schemes. The examples include two problems with known analytic solutions, enabling error evaluation of the different schemes on various grids (9–18 points per wavelength). We use our block-parallel CARP-CG algorithm [Parallel Computing 36, 2010] for solving the equations. T...

objective: carpal tunnel syndrome (cts) is the most frequent local neuropathy which often relapses despite treatment. this study is performed to determine the frequency of obsessive compulsive disorders in cts as a main reason for relapse in patients referring to electro-diagnosis clinic during year 2007. methods: in a case control study we considered two groups of subjects: with cts (cases) an...

This paper presents a low-area and low-power consumption CMOS differential current controlled oscillator (CCO) for neuromorphic applications. The oscillation frequency is improved over the conventional one by reducing number of MOS transistors thus lowering load capacitor in each stage. analysis shows that same power consumption, can be increased about 11% compared with without degrading phase ...
