Method The randomized double blind controlled trial of 40 obese adolescent boys aged 14-18 years old were performed on March-May 2011. Subjects were classified into 2 groups, the Vitamin C 500 mg treatment group and the control group which got placebo, twice daily for 8 weeks. The ICAM-1 concentration of both groups was examined before and after the treatment. The data were analyzed with paired...

This study aims to determine the heatwave announcement in China can increase Indonesia's coal export potential. On abnormal Return on shares of PT Bumi Resource Tbk (BUMI) and Adaro Energy Indonesia (ADRO). The method used analyze this research is an event study. Hypothesis testing was carried out using normality tests, paired sample t-tests one-sample T-tests. From results study, it found that...

The purpose of this study was to determine the effect variations in leg muscle training on jumping results extracurricular volleyball players at SMPN 1 Bangkalan. Which aims find out whether there is an research method uses a quasi-experimental design (pseudo-experiment). data analysis technique used paired sample t-test, with t-test where t-count = 16.20 significant level obtained that value t...

We describe an enzymatic method, requiring only 10 mul of serum, for determining CO2 as bicarbonate or dissolved gas. Phosphoenolpyruvate carboxylase catalyzes the reaction of HCO3- with phosphoenolypyruvate to give oxalacetate. The resulting NADH, in the presence of malate dehydrogenase, is oxidized to NAD+, and the decrease in absorbance at 340 nm is directly proportional to the amount of CO2...

BACKGROUND Previous work from this laboratory has evidenced the biomechanical role of forearm osseoligamentous structures in load transfer of applied forces. It has shown that forces transmitted across the distal radioulnar joint (DRUJ) and proximal radioulnar joint (PRUJ) are similar, though not identical, under axial loading conditions. The purpose of the study was to assess the articulating ...

The change in T 1-hypointense lesion ("black hole") volume is an important marker of pathological progression in multiple sclerosis (MS). Black hole boundaries often have low contrast and are difficult to determine accurately and most (semi-)automated segmentation methods first compute the T 2-hyperintense lesions, which are a superset of the black holes and are typically more distinct, to form...

The behaviour of group sequential tests in the two-sample problem is investigated if one replaces the classical non-robust estimators in the t-test statistic by modern robust estimators of location and scale. Hampel's 3-part redescending M-estimator 25A used in the Princeton study and the robust scale estimators length of the shortest half proposed by Rousseeuw & Leroy and Q proposed by Roussee...

Ask experts what would be an important reduction in amount consumed. Need some idea of the SD of a within-child difference in consumption from a four hour period in one day to a four hour period in another day. Could do a pilot study with say 10 children measured [without any intervention] on two different days and get the SD of the 10 differences. Then use sample size formula for 1 sample t-te...

Smartphone addiction is an overuse of mobile device, usually quantified as the number times users access their devices. Aim study was to assess effectiveness structured teaching programme on knowledge regarding health hazards phone addiction. Quantitative research approach used with Non-Randomized pre- test post-test control group design. Non-probability Convenient Sampling Technique select sam...
