Topological indices are numerical parameters of a molecular graph G which characterize its topology. On the other hands, computing the connectivity indices of molecular graphs is an important branch in chemical graph theory. Therefore, we compute First Zagreb index Zg   <span style="font-family: TimesNewRomanPS-Italic...

World Health Organization has identified violence against children as a growing public-health issue with a global magnitude. This paper explored violence against children as a challenge in the developing world using Pakistan as a case study. A systematic review of existing research and literature on violence against children was followed by assessing the magnitude of this challenge and its impa...

It is generally accepted that differences in the mean haemoglobin level in the two sexes become apparent after puberty, and this is thought to be due mainly to a gradual rise in the mean level in boys, which continues until about the age of 16 or 17 years (Sunderman, MacFate, MacFayden, Stevenson, and Copeland, 1953). However, in addition to age and (after puberty) to sex, many other factors ar...

Since the transition to democracy in Spain in 1975, both total fertility and rates of church attendance of Catholics have dropped dramatically. In this study the 1985 and 1999 Spanish Fertility Surveys were used to investigate whether the significance of religion for fertility behaviour -- current family size and the spacing of births -- changed between the survey dates. In the 1985 survey, fam...

We obtain limit theorems for the row extrema of a triangular array of zero-modified geometric random variables. Some of this is used to obtain limit theorems for the maximum family size within a generation of a simple branching process with varying geometric offspring laws.
