This research aims to determine the relationship between self-concept, reading attitudes, and comprehension of ninth grade students SMPN 51 Palembang. In this study 30 were selected as a stratified random sample. tests are used collect data. The analysis was performed using Pearson product moment correlation coefficient, Normality Test, Homogeneity Linearity Test multiple regression. results sh...

A proteolytic enzyme was isolated from human senile cataractous lens by anion-exchange and gel-filtration chromatography. Sedimentation and zoneelectrophoretic experiments indicated a high degree of homogeneity for the enzyme. A molecular weight of 27000 was calculated from measurements of sedimentation velocity and diffusion coefficient. Chelating agents decreased activity which could be resto...

By utilizing conventional techniques of pressure ultrafiltration, gel filtration chromatography, diethylaminoethyl cellulose chromatography, and preparative polyacrylamide electrophoresis, the A component of the group D lysin produced by Streptococcus zymogenes has been purified to a state of apparent homogeneity when determined by the techniques of anionic and cationic disc gel electrophoresis...

The uniformity of remolded loess samples prepared in the laboratory directly determines reliability various test results. While many tests have been designed to reflect properties undisturbed loess, there are obvious structural differences between and loess. Therefore, it is great theoretical practical significance explore a non-destructive evaluation index structure for indoor geotechnical tes...

EBT2 film is widely used for quality assurance in radiation therapy. The purpose of this study was to investigate the homogeneity of EBT2 film among various lots, and the dose dependence of heterogeneity. EBT2 film was positioned in the center of a flatbed scanner and scanned in transmission mode at 75 dpi. Homogeneity was investigated by evaluating gray value and net optical density (netOD) wi...

The paper provides an assessment of Tuz Gölü, a site in Turkey proposed for the radiometric vicarious calibration of satellite sensors, in terms of its spatial homogeneity as expressed in visible and near-infrared (VNIR) wavelengths over a 25-year period (1984–2009). By combining the coefficient of variation (CV) and Getis statistic (Gi*), a spatially homogenous and temporally stable area at le...

This paper is a state of the art of the understanding on the physics of homogeneous dielectric barrier discharge at atmospheric pressure. It is based on the analysis of present and previous work about the behavior of these discharges and the conditions to get them. Mechanisms controlling the homogeneity during gas breakdown and discharge development are successively discussed. The breakdown has...
