birth and death indicators were examined through retrospective surveys conducted in 1985 and 1987 in the islamic republic of lran, reviewing 1984 and 1986 events, to obtain infant mortality rate (imr) and other necessary indicators for health planning and evaluation. comparison between 1985 and 1987 surveys revealed: 1. no major change in crude death rate ( 6.3 per 1000 in 1987 survey) had occu...

In this paper, we firstly show that the $N$-dual operation of the right residual implication, which is induced by a left-conjunctive right arbitrary $vee$-distributive left semi-uninorm, is the right residual coimplication induced by its $N$-dual operation. As a dual result, the $N$-dual operation of the right residual coimplication, which is induced by a left-disjunctive right arbitrary $wedge...

The set Set(n), generated by an arbitrary natural number n, was defined in [2] and some arithmetic functions, over its elements are introduced algebraic aspect. Here, the of two functions similar to modal type operators their basic properties studied.

background: hypertension is one of the most important determinants of death due to vascular damage and is fast emerging as a high burden disease in india. however, its documentation is poor in the country. this study aims to estimate the rate and the causal pattern of mortality in a cohort of people with high blood pressure as compared to normotensives. methods: the study setting is varkkala, a...

Given measurements of the number of customers in a queueing system over a finite time interval, it is natural to try to fit a stationary birth-and-death process model, because it is remarkably tractable, even when the birth and death rates depend on the state in an arbitrary way. Natural estimators of the birth (death) rate in each state are the observed number of transitions up (down) from tha...
