In studying the ultraviolet (UV) radiation, one of the important factors is the possibility of generating a variety of free radicals inside the body by these radiations. In this paper, a method of estimating the amount of hydroxyl radicals produced by ultraviolet rays was investigated using nanoparticles of tin oxide doped with uropium. In this method, the change in absorption intensity of meth...
Background: Little is known about the influence of habitual participation in physical exercise and diet on upper-extremity physical function in older adults. To assess the relationship of general physical exercise and diet to upper-extremity physical function and pain intensity in older adults. Methods: A cohort of 111 patients 50 or older completed a sociodemographic survey, the Rapid Asse...
Abstract. Considering the need to save energy consumption in less developed countries, it seems necessary to identify the effective factors of energy growth in the economy of OPEC countries. Energy intensity represents the energy required to produce a unit of product at the national level. Energy intensity at the level of an industry or a specific production process is calculated in terms of ph...
A critical issue in the probabilistic framework for performance-based earthquake engineering is the choice of ground motion intensity measure(s). In an effort to identify optimum intensity measure(s), a comprehensive parametric statistical study based on 881 earthquake record components was conducted to identify the correlation between (1) seismological variables (SV’s) and traditional ground m...
In this paper, we examine the effect of intra-industry credit contagion using three different kinds of intra-industry measures in our empirical study. We apply the competitive strategic measure (CSM) of Sundaram et al. (1996) to capture the strategic interaction faced by firms. We also consider the measure of industry-wide financial distress and the measure of equity correlations. We use the fo...
Under image scaling transform, two interaction models of image intensity gradient fields display unusual power scaling laws. These scalings are very universal in texture images and images of natural scenes, and robust against noise and image local deformation. An image similarity measure is developed in terms of these scaling laws. This similarity measure has graceful properties such as invaria...
A quantitative measure of the Modified Mercalli Intensity Scale for earthquakes in ~he western United States has been developed by correlating the peak seismoscope relative displacement response, Sd, with the reported site intensity, IMM. This correlation can be approximated by
Analysis of the seismic risk to a structure requires assessment of both the rate of occurrence of future earthquake ground motions hazard and the effect of these ground motions on the structure response . These two pieces are often linked using an intensity measure such as spectral acceleration. However, earth scientists typically use the geometric mean of the spectral accelerations of the two ...
