human body consists of some tissues among which bone is one of the important living and growing tissue . in this research, energy absorption buildup factor (eabf) values of 27 types of bone have been computed for photon energy 0.03 to 1.5 mev up to 40 mean free path (40mfp) penetration depths. the inner bone tissue, spongiosa and male sternum had the largest values of eabf in low photon energie...

The discrepancy in the literature concerning the sensitivity of delayed P300 latency in dementia revolves around the variability of P300 latency in normal elderly. Previous studies, which have produced conflicting results, have utilized different P300 paradigms and different methods for measuring P300 latency. We demonstrate that the reported differences in the variability of P300 latency in no...

A computer-simulation model (MELSIM) of a Meloidogyne-grapevine system is developed. The objective is to attempt a holistic approach to the study of nematode population dynamics by using experimental data from controlled environmental conditions. A simulator with predictive ability would be useful in considering pest management alternatives and in teaching. Rates of flow and interaction between...

We take a semiparametric approach in fitting a linear transformation model to a right censored data when predictive variables are subject to measurement errors. We construct consistent estimating equations when repeated measurements of a surrogate of the unobserved true predictor are available. The proposed approach applies under minimal assumptions on the distributions of the true covariate or...

pedomodels have become a popular topic in soil science and environmentalresearch. they are predictive functions of certain soil properties based on other easily orcheaply measured properties. the common method for fitting pedomodels is to use classicalregression analysis, based on the assumptions of data crispness and deterministic relationsamong variables. in modeling natural systems such as s...

In 1967, the first multicenter randomized controlled trial of treatment for hypertension was published by the newly created Veterans Administration Cooperative Studies Program, demonstrating the remarkable effectiveness of drug treatment for what would now be considered severe hypertension (average diastolic pressure 115 to 129 mm Hg).1 During the ensuing 4 decades, there have been remarkable s...

The analytical solution of recurrent equations for amplitudes of electromagnetic field is found for description of x-ray reflection and diffraction from periodical multilayered media. The method proposed uses the Bloch eigenwaves approach for periodical structure, which reduces considerably the computer time required for simulation of diffracted/reflected x-ray intensity and, therefore, acceler...

Llewellyn, M. A., Tilak, K. S., and Swyer, P. R. (1970). Archives of Disease in Childhood, 45, 453. A controlled trial of assisted ventilation using an oro-nasal mask. A controlled study was performed to assess the effect of early assisted ventilation using a tight fitting face mask. Early mask ventilation reduced the number of infants requiring intubation, but did not significantly alter the s...
