The kinetics and mechanism of ligand substitution reactions of [Pt(SMC)Cl(2)] (SMC = S-methyl-l-cysteine) with biologically relevant ligands were studied as a function of chloride and nucleophile concentrations at pH 2.5 and 7.2. It was observed that the slope and intercept obtained from the linear dependence of the observed rate constant on the nucleophile concentration strongly depend on the ...

Background. This article evaluates correction of rib hump in patients with idiopathic thoracic scoliosis who had been treated by the Cotrel-Dubousette method. Material and methods. We investigated 35 patients pre- and postoperatively in this study. Back surface measurements were studied pre- and postoperatively using our own device. Scoliosis correction was assessed by comparing pre- and postop...

In this study we have investigated in influence of location, gender and orientation on the deformation characteristics of 55 samples of human excised skin. Uniaxial tensile tests were carried out at a strain rate of 0.012s on excised human skin from the back. The deformation characteristics of skin (Ultimate Tensile Strength (P<0.0001), Failure Strain (P=0.0177), Young’s Modulus (P<0.0076), Ini...

[Purpose] The purpose of this study was to investigate the effects of 6 weeks sling exercise training for clients with low back pain on the levels of pain, disability, muscular strength and endurance. [Subjects and Methods] Twelve chronic LBP subjects participated in this study. Subjects were randomly divided into a control group and a training group. Subjects in the training group performed sl...

the effects of different climatic, soil, geometric, and management factors on soil organic carbon (soc) degradation and sequestration potential was evaluated in the semi-arid zone of mereg watershed, west of iran. two nonparametric methods, viz. classification and regression tree (cart) and feed forward back propagation artificial neural network (ann) were compared with parametric multivariate ...

Temporal and spatial spectral analysis techniques were applied to lidar data collected over a period of 18 months above the Rocky Mountain region at an altitude range from 45 to 70 km by a Rayleigh lidar system located in Logan, Utah (41.7øN, 111.8øW). Examination of the averaged temporal frequency F(co) and vertical wavenumber F(m) spectra showed spectral slope values of1.49 + 0.03 and -2.3 + ...

We study the physical processes that create eroded channels and drainage networks by doing laboratory experiments. The apparatus consists of a sloping granular bed inside a 90 cm 119 cm 30 cm acrylic box. The granular material consists of 0.5 mm diameter glass beads. Water is fed from a reservoir in the back and the pressure is maintained at a constant level. The water seeps through the porous ...

Hybrid poplars have demonstrated high productivity as short rotation woody crops (SRWCs) in the U.S. Midwest, and the hybrid aspen ‘Crandon’ (Populus alba L. × P. grandidenta Michx.) has exhibited particularly promising yields across topographic positions (including sloping marginal lands) in Iowa. However, a key obstacle for landowner acceptance of SRWCs is the lack of economic returns early i...

INTRODUCTION Around 40% of people presenting to primary care with an episode of acute low back pain develop chronic low back pain. In order to reduce the risk of developing chronic low back pain, effective secondary prevention strategies are needed. Early identification of at-risk patients allows clinicians to make informed decisions based on prognostic profile, and researchers to select approp...
