introduction: the information recorded in medical sheets can help us facilitate the treatment process, recognize the quality of performance of the medical staff, plan health care programs and make accurate and appropriate decisions. this study intends to compare the quality of recording information in admission and summary sheets of three hospitals in isfahan in the first six months of 1381. ma...

the use of twb has been developed in automotive industries because of it’s advantages such as reduction in weight, cost and fuel economy of vehicles. the main objective of the peresent work is to study the effects of weld zone, diffrence in surface coating and thickness ratio on the formability of twb composed of aisi 304, spcc and if steel sheets. it was found that the narrow weld zone has lit...

europium (eu) doped zno microsphere based nano-sheets were synthesized through hydrothermal method. effects of different concentrations of europium on structural and optical properties of zno nano-sheets were investigated in detail. prepared un-doped and eu-doped zno samples were characterized using x-ray diffraction (xrd), energy dispersive x-ray spectroscopy (edx), scanning electron microscop...

in this work, laser bending of perforated sheets has been investigated numerically. laser bending of perforated sheets is more complicated than non-perforated sheets due to their complex geometries. in this paper, laser bending of perforated sheets is studied numerically in the form of thermo-mechanical analysis with abaqus/implicit code. for this purpose, the effects of process and sheet param...

a modified electrode was prepared by modification of the carbon paste electrode (cpe) with graphene nano-sheets. the fabricated modified electrode exhibited an electrocatalytic activity toward gallic acid (ga) oxidation because of good conductivity, low electron transfer resistance and catalytic effect. the graphene modified cpe had a lower overvoltage and enhanced electrical current respect to...

two potassium oxalate doped tio2 samples, designated as k1-tio2 and k2-tio2, were synthesized by the base-catalyzed sol-gel process. these samples were impregnated into rubber sheets. two commercial tio2 samples, anatase and degussa p25, were used as reference materials with which the synthesized samples were to be compared. anatase and p25 were also impregnated into rubber sheets and designate...

in this paper, the effect of cyclic loading on punching strength of flat slabs strengthened with carbon fiber reinforced polymer (cfrp) sheets is studied. experimental results of ten slab specimens under monotonic and cyclic loading are analyzed. eight specimens were strengthened with cfrp sheets on the tensile face of the slabs and the two other specimens were kept un-strengthened as control s...

Background We previously conducted a first-in-human clinical study of articular cartilage repair using autologous chondrocyte sheets and confirmed the regeneration of hyaline-like cartilage in all eight patients. However, regenerative medicine with autologous chondrocyte sheets requires the harvesting of tissue from healthy regions, and the quality of this tissue varies between individuals. To ...
