For most living beings, oxygen is an essential molecule for survival, being the basis of biological oxidations, which satisfy energy needs aerobic organisms. Oxygen can also behave as a toxic agent posing threat to existence beings since it give rise reactive species (ROS) that oxidise macromolecules, among proteins and lipids are preferred targets. Oxidative damage induce cell, tissue, organ d...

This article deals with ambiguous surface digitizations by dilation in n-dimensional space. The digitization of a sufficiently regular surface is separating but not necessarily minimal. We will determine conditions under which the supercover and the grid intersection digitizations are discrete surfaces. It will also be proven that non-overlapping domains do not solve the problem of simple point...

Studies show that discourses are important in legitimating emerging fields. However, we still lack understanding of how potential participants’ interpretations of discourses shape their involvement in emerging fields particularly when the field’s definition is ambiguous. Drawing on an indepth study of the emerging nanotechnology field we show that individuals’ affective responses to discourses ...

Currently the Dempster-Shafer based algorithm and Uniform Random Probability based algorithm are the preferred method of resolving security games, in which defenders are able to identify attackers and only strategy remained ambiguous. However this model is inefficient in situations where resources are limited and both the identity of the attackers and their strategies are ambiguous. The intent ...

background: mixed infection with amphistomes seems common in native cattle of iran. the aim of this study was to determine diagnostic antigens in cattle mixed amphistomiasis. methods: specific antigens of cotylophoron cotylophorum , gastrothylax crumenifer and paramphisto­mum cervi (mixed infection), the most common species, were collected from cattle was deter­mined. adult trematodes were coll...
