wild boar is distributed throughout iran except highly arid areas. in recent years, however, population size of wild boar has increased primarily because of reduction in population size of natural predators such as leopard. conversely, changes in land-use practices and increase in foraging of livestock in natural habitats has led to reduction of food resources and consequently, has forced the s...

Abst rac t . Given axis-parallel rectangular obstacles and crossing areas together with two pairs of terminals on the plane, our algorithm finds a shortest pair of rectilinear paths which connect the pairs of terminals and neither pass through any obstacle nor cross each other except in the crossing areas. The algorithm takes O(nlog n) t ime and O(n) space, where n is the total number of obstac...

This study assessed the chemical and microbial contents in the water of public swimming pools in Akwa Ibom State, Nigeria. A total of 16 public pools were selected through probability sampling from the 32 pools that existed in the five urban areas of Akwa Ibom State.

Preface Except II is a system that supports several kinds of reasoning ranging from basic deduction and abduction to high-level forms such as diagnosis, connguration, and induction. Its main and characteristic feature that enables this is default reasoning. Default reasoning is an attempt to handle defeasible inferences properly and to provide qualitative, argument-based methods for deciding be...

Autopsy/cadaver data indicate that many organs and tissues are smaller in the elderly compared with young adults; however, in vivo data are lacking. The aim of this study was to determine whether the mass of specific high-metabolic-rate organs is different with increasing age, using MRI. Seventy-five healthy women (41 African-Americans and 34 Caucasians, age range 19-88 yr) and 36 men (8 Africa...
