background and objectives: endophytic actinobacteria colonize inside the plant tissues without causing damages to the host plant. since these microorganisms colonize in the different parts of plants and can stop plant disease, they have been applied as biological agents for controlling human diseases. the aim of this study was molecular identification and measuring the antimicrobial activity of...

introduction: adhesion formation after pelvic surgery is still a major cause of several morbidities such as infertility, pain, bowel obstruction and subsequent intra-operative complications. our aim was to investigate the effects of d-penicillamine in preventing adhesion formation in rat uterine horn. methods: this experimental trial was conducted on 30 rats. the rats were randomly assigned to ...

diabetes mellitus is a progressive disease. most investigators have focused on glomerular changes in diabetic kidney and non-glomerular alterations have been less attended. the present study has been conducted to find early non-glomerular histological changes in diabetic renal tissue. twenty male wistar rats weighting 200-250 g were used for the diabetic group. diabetes mellitus was induced by ...

nowadays novel is one of the most important patterns of story writing and indeed is an image of real life and the era that it was written in. the present article studies an era of social and political life of egyptians by studying “in darkness” as a novel written by najib alkeilani who is an egyptian contemporaneous author. najib alkeilani wrote this novel when he was in prison in 1957 ad.

Facility location decisions play a prominent role in strategic planning of many firms, companies and governmental organizations. Since in many real-world facility location problems, the data are subject to uncertainty, in this paper, we consider the P-center problem under uncertainty of demands. Using Bertsimas and Sim approach, we develop a robust model of the problem as an integer programming...

Facility location-allocation models are used in a widespread variety of applications to determine the number of required facility along with the relevant allocation process. In this paper, a new mathematical model for the capacitated multi-facility location-allocation problem with probabilistic customer's locations and fuzzy customer’s demands under the Hurwicz criterion is proposed. Thi...

This paper studies a covering problem on graph which is a variant of facility location problem. In this research, constraints are considered to improve the previous model. These constraints have not considered previously. The first constraint limits the capacity of the facilities and the other one considers different coverage distances. The objective is to determine the optimal subset of candid...

The problems of facility location and the allocation of demand points to facilities are crucial research issues in spatial data analysis and urban planning. It is very important for an organization or governments to best locate its resources and facilities and efficiently manage resources to ensure that all demand points are covered and all the needs are met. Most of the recent studies, which f...
