introduction in computed tomography (ct) technology, an optimal radiation dose can be achieved via changing radiation parameters such as ma, pitch factor, rotation time and tube voltage (kvp) for diagnostic images. materials and methods in this study, the brain, abdomen, and thorax scaning was performed using toshiba 16-slice scannerand standard aapm and ctdi phantoms. aapm phantom was used for...

Herein, we report a one-step synthesis method for octahedral Pt-Ni-Co ternary catalysts with tunable compositions and fixed shapes. Impressively, the composition optimized octahedral PtNi0.55Co0.1/C demonstrated a significant improvement in ORR activity compared to those of previously reported Pt-Ni-Co alloy octahedra, showing an outstanding specific activity of 5.05 mA cm-2 and a mass activity...

background: increased thoracic kyphosis more than normal ranges are assessed as abnormal. but normal ranges of thoracic kyphosis in deferent age groups have not been identified in our country yet. the aim of present study was investigation of normal ranges of thoracic kyphosis to use as a diagnosis tool in school aged children in kermanshah, western-iran. methods: a descriptive research designe...

Following the finding of in vitro insulinominetic activities of new prepared Zn(II) complexes with amide ligands (2-picolinamide (pa-a) and 6-methyl-2-picolinmethylamide (6mpa-ma)) in isolated rat adipocytes treated with epinephrine in terms of inhibition of free fatty acid release, their blood glucose normalizing effects were observed on daily intraperitoneal injections for 14 d in a type 2 di...

The chemical name in the title, the formula and the scheme of the paper by Gu, Hao, Song, Lin & Ma [Acta Cryst. (2008), E64, m649-m650] are corrected.[This corrects the article DOI: 10.1107/S1600536808009380.].

Mechanical properties and morphologies of HDPE/bamboo flour (BF) composites modified with two maleated ethylene/propylene elastomers (EPR-g-MA) and one maleated polyethylene (PE-g-MA) were investigated. The concentration of each modifier varied between 0 and 8.3 wt% based on the total composite weight. The highest values in strengths and moduli were achieved for the composites containing PE-gMA...

A sensitive and simple liquid chromatography/electrospray mass spectrometry (LC-MS/MS) method for determination of gefitinib in rat plasma using one-step protein precipitation was developed. After addition of estazolam as internal standard (IS), protein precipitation by acetonitrile was used as sample preparation. Chromatographic separation was achieved on an SB-C18 (2.1 mm × 50 mm, 3.5 μm) col...

Introduction In computed tomography (CT) technology, an optimal radiation dose can be achieved via changing radiation parameters such as mA, pitch factor, rotation time and tube voltage (kVp) for diagnostic images. Materials and Methods In this study, the brain, abdomen, and thorax scaning was performed using Toshiba 16-slice scannerand standard AAPM and CTDI phantoms. AAPM phantom was used for...
