The cultivated apple (Malus domestica) is one of the most important fruit crops cultivated in different regions of the world including Iran. For production and breeding of high quality apple, the knowledge of genetic diversity of the cultivated apples is necessary. Therefore we studied genetic diversity of 25 genotypes by using ISSR molecular markers. In present study, ten ISSR primers produc...
Application of multivariate techniques in-line with spatial regionalization of AOD over Iran Introduction Models, satellites and terrestrial datasets have been used to detect and characterize aerosol. Nontheless, micoscale classification using remote sensing parameters considers as a deficiency. Thus, regionalizion and modeling aerosol without regard to political boundaries or a specific s...
the zoning of phenomena based on geographical location has a long history; any geographical zone is a part on ground level, which possesses noticeable internal consistency in terms of its existing phenomena and processes. agroclimatic zoning is mainly purposed to determine agroclimate regions and to evaluate these zones based on their relative utility in order to cultivate varieties of agricult...
DNA markers are integrally connected to the success of molecular breeding and are fundamentally required by breeders to be able to, a. identify new gene sources in the available biodiversity, b. select parents in order to increase heterosis, c. decrease the number of backcross generations for gene introgression breeding programs, and d. carry out marker-assisted selection (MAS). The present re...
Background and purpose: Road accidents are a major cause of mortality throughout the world especially in undeveloped and developing countries. Mazandaran Province in Iran has one of the busiest roads with a high rate of accidents and fatalities. Environmental and social conditions influence this problem. This study aimed at exploring the social and geographical pattern of mortality due to road ...
BACKGROUND Oncomelania hupensis is the unique intermediate host of Schistosoma japonicum, which causes schistosomiasis endemic in the Far East, and especially in mainland China. O. hupensis largely determines the parasite's geographical range. How O. hupensis's genetic diversity is distributed geographically in mainland China has never been well examined with DNA sequence data. METHODOLOGY/PR...
BACKGROUND Environmental habitat may play a role in clinical disparities of primary hyperparathyroidism (pHPT) patients. AIMS To compare preoperative clinical symptoms and associated conditions and surgical findings in patients with pHPT, living in different geographical regions from the Black Sea, Mediterranean and Anatolia regions. STUDY DESIGN Retrospective, clinical-based multi-centric ...
We suggest that the proximity of a country to other countries is a factor that affects its choice as an MNE location. We introduce the concept of a country’s proximity to the global distribution of knowledge, markets and resources, and frame this concept as a function of both geographic distance and the worldwide spatial distribution of these factors. We test our location model on a dataset com...
spatial distribution of thermal regions is dependent on local factors and circulation patterns in long terms. recognition of spatial distribution of temperature in geographical regions could be help on planning and environmental policies. the aim of this paper is recognition and detachment of thermal regions in iran. for this object, maximum daily temperature data have been provided using 620 s...
Geographical range dynamics are driven by the joint effects of abiotic factors, human ecosystem modifications, biotic interactions and the intrinsic organismal responses to these. However, the relative contribution of each component remains largely unknown. Here, we compare the contribution of life-history attributes, broad-scale gradients in climate and geographical context of species' histori...
