desertification in arid, semi-arid and dry sub-humid regions is a global environmental problem. considering theincreasing importance of desertification and its complexity, the necessity of giving attention to desertification criteria andindices is essential. models and methods such as medalus, unep-fao, and others have been proposed on local andnational scales. in this research, imdpa was selec...

desertification is more related to social and anthropogenic issues than natural causes and it becomes moreimportant over the time. human effects on desertification could be classified as direct and indirect factors. this studyhas focused on the effect of management factor, as a dominant case, on desertification of kashan region based onimdpa (imdpa: iranian model of desertification for potentia...

BACKGROUND AND PURPOSE Candida species are considered a common cause of fungal blood stream infections, which are associated with considerable mortality and morbidity rates, especially in the admitted and immunocompromised patients. Despite the increase in new and available antifungal agents, the emergence of resistant strains is growing. Regarding this, the aim of the present study was to asse...

a number of grapevine cultivars have female flowers and for better fruit set, they need pollinizer. single planting of these cultivars leads to severe decrease in fruit set. this research was carried out to investigate the effect of cross pollination with four grape cultivars (askari, rish baba, bidane sefid and tabarze sefid) on fruit set, bunch weight, berry per cluster, average weight of 20 ...

OBJECTIVE Grape virus diseases are a serious problem in Iran. Leaves and fruits of grape have been used for different purposes like cooking in Iran. The present investigation was carried out to study on the cytotoxic-activities of extracts of fruits and leaves of Vitis vinifera from both virus-free and virus-infected grape cultivars against breast cancer cell line (MDAMB- 231) and human embryon...
