Background Maternal death is a key qualitative reliable index of a nation’s economic development. The present research aims to investigate causes of maternal mortality in Iran. Materials and Methods A systematic review of the following databases led us to find the target articles: Medline (via PubMed), Science Direct, CINAHL, CINAHL (EBSCO), Scopus, Web of Science, SID, ISC, Magiran, and Goog...
We study the thermophoretic motion of a micron sized single colloidal particle in front of a flat wall by evanescent light scattering. To quantify thermophoretic effects we analyse the nonequilibrium steady state (NESS) of the particle in a constant temperature gradient perpendicular to the confining walls. We propose to determine thermophoretic forces from a "generalized potential" associated ...
able amounts of radiolabeled dextran in the plasma protein fraction [15]. Consequently, we do not think this mechanism plays a substantial role in producing the lower than expected dextran concentrations seen in the present study. The dextran we used had a mean molecular mass of 70 000 Da. Thus, some quantity of lower-molecular-mass dextran could have leaked out of the vascular space and distri...
The electromagnetic field of visible light performs approximately 10(15) oscillations per second. Although many instruments are sensitive to the amplitude and frequency (or wavelength) of these oscillations, they cannot access the light field itself. We directly observed how the field built up and disappeared in a short, few-cycle pulse of visible laser light by probing the variation of the fie...

There is a glaring paradox in all commonly used measures of poverty. The death of a poor person reduces poverty according to these measures. This surely violates our basic intuitions of how poverty measures should behave. It cannot be right in concept that differentially higher mortality among the poor serves to reduce poverty. This paper begins the task of developing poverty measures that are ...
In making comparisons of the mortality of different occupational groups, it is essential to allow for differences in the age distributions of the groups. The principle of "standardizing" for age is long established. Each of the two conventional methods, direct and indirect, leads to a "Standardized Mortality Ratio" (S.M.R.) which is a weighted average of the ratios of the death rates, by ages, ...
