BACKGROUND Term infants who are small for gestational age appear prone to the development of insulin resistance during childhood. We hypothesized that insulin resistance, a marker of type 2 diabetes mellitus, would be prevalent among children who had been born prematurely, irrespective of whether they were appropriate for gestational age or small for gestational age. METHODS Seventy-two healt...

The process performance index (PPI) can be a simple metric to connect the conforming rate of products. properties PPI have been well studied for normal distribution and other widely used lifetime distributions, such as Weibull, Gamma, Pareto distributions. Assume that quality characteristic product follows power-normal distribution. Statistical inference procedures are established. maximum like...

There is now evidence that many long-standing international plumbing codes significantly overestimate the peak water demand in multilevel residential buildings. The overestimation of this design value may have adverse effects on construction cost, energy consumption, quality, and safe operation. This research aims to assess performance current Australian New Zealand cold standard for A literatu...

Analysis of QT interval from repeated recordings was made in 56 patients with documented idiopathic mitral valve prolapse (IMVP). The results were compared with a control of 62 healthy volunteers in whom mitral valve prolapse was excluded by both phonocardiography and echocardiography and with two other standard populations, those of Simonson and co-workers and of Ashman. After correction for a...

A repeated-measurements model with a functional structure in varlancecovariance is employed to analyze the degradation data collected from an accelerated life-test experiment. A transformation is utilized to permit the calculation of the generalized least-squares estimators and their covariance matrices by ordinary leastsquares regression. The mean and percentile of the distribution of the time...

• Limit dose test – this is the preferred test when toxicity is expected to be low and lethality is unlikely at the limit dose. The limit dose must be adequate for assessment purposes, and it is usually 2000 mg/kg body-weight. • Full test: LD50-only test – this is the preferred test when an estimate of the median lethal dose is required but neither the slope of the dose response curve or the co...

The reference interval for plasma total homocysteine (tHcy) and serum folate concentrations were estimated. Total of 3,154 reference individuals (1,029 men and 2,125 women) were selected based on stringent exclusion criteria. For plasma tHcy concentration (µM/L), reference values (median [5-95 percentile]) were 7.72 (5.03 to 13.80) and 6.09 (3.95-10.19) in men and women, respectively. For serum...
