Free radical can be defined as a molecule or molecular fragments containing unpaired electron in the outer orbital, which react with nearby molecules to get stability. There are two types of them in the body: oxygen free radicals and nitrogen free radicals. Our body has an antioxidant defense system which prevents accumulation of these radicals. There is a balance between free radical produc...

1. introduction with regard to natural and human urban threats and risks which endanger security of the residents, ensuring urban safety and passive defense issues, especially before being hit by crisis and in peace situation such as natural disasters, war, etc., are the most significant duties of urban practitioners and planners. the main criterion of passive defense viewpoint is to increase t...

Introduction: In today's world, “It is believed that use of microbial agents and biological toxins are harmful for human health. Food industry is a soft target and potentially vulnerable to deliberate contamination. The manufacturing units of dairy industry are a good example. The purpose of this study was to determine the level of food defense preparedness of dairy production units using FDA F...

allusion: from 2 years ago, a community-centered group in holy defense research and documentation center has been formed to respond the needs of the general audiences in the community. from the beginning, the group sought to identify the needs of different ranges of the target community and to produce suitable products for it. almost a year after forming and stabilizing, the group paid attentio...

In 2D Soccer Simulation league, agents will decide based on information and data in their model. Effective decisions need to have world model information without any noise and missing data; however, there are few solutions to omit noise in world model data; so we should find efficient ways to reduce the effect of noise when making decisions. In this article we evaluate some simple solutions whe...

Speci"c defense protects against some parasite genotypes but not others, whereas non-speci"c defense is e!ective against all genotypes of a parasite. Some empirical studies observe hosts with variability only in non-speci"c defense, other studies "nd only speci"c defense. I analyse a model with combined speci"c and non-speci"c defense to determine the conditions that favor detectable variation ...
