The piped water consumption per capita is more than 142 cubic meters per year in Iran that is higher than the consumption per capita of some water-filled European countries such as Belgium and Austria. The use of drinking water for washing dishes, clothes, cars as well as bathing and watering gardens are of the important reasons for piped water high consumption in Iran. However, different lifes...

introduction: in addition to the annual mortality rate, unintentional home injury may result in temporary or permanent disability and requires medical attention and continuous care in millions of children. this study aimed to explore features and risk factors of these injuries. methods: in this cross-sectional study, demographic variables and epidemiologic pattern of home injuries among childre...

background: the first three years of life have a pivotal role in growth and development of infants. extra-uterine environment largely affects brain development of infants during the first year of life.however,no specific programs are available for brain development stimulation in foster homes. aim: this study aimed to evaluate the effects of motor development stimulation package on anthropometr...

scholars have long been interested in the role of population and its impact on the economy of various countries, hence the theories on the subject. while malthus’ population theory presents a very pessimistic view and is formulated in a context which does not correspond to the conditions of the modern world, it occupies the minds of a majority of economists. it is interesting to know, while mal...

Habitat selection is an active behavioral process that may vary across spatial and temporal scales. Animals choose an area of primary utilization (i.e., home range) then make decisions focused on resource needs within patches. Dominance may affect the spatial distribution of conspecifics and concomitant habitat selection. Size-dependent social dominance hierarchies have been documented in capti...

Animal home ranges may vary little in their size and location in the short term but nevertheless show more variability in the long term. We evaluated the degree of site fidelity of two groups of spider monkeys (Ateles geoffroyi) over a 10- and 13-year period, respectively, in the northeastern Yucatan peninsula, Mexico. We used the Local Convex Hull method to estimate yearly home ranges and core...

Among species of lizards, endurance capacity measured on a motorized treadmill is positively related to daily movement distance and time spent moving, but few studies have addressed such relationships at the level of individual variation within a sex and age category in a single population. Both endurance capacity and home range size show substantial individual variation in lizards, rendering t...
