Background and purpose: Crimean Congo Hemorrhagic Fever (CCHF) is a dangerous viral zoonotic disease. Ticks are the main vector which transmit CCHF virus from livestock to human. The present study was done to provide a comprehensive database on major ticks in the CCHF virus transmission and their geographical dispersal in Iran. This would be of great benefit in planning for intelligent control ...
Assessment of forest soil and vegetation characteristics provides basic and essential information for the protection and rehabilitation measures in forest ecosystems. Therefore, regard to the importance of this issue, the distribution of different soil properties and vegetation diversity in relation to conservation management and degradation investigated in the oak forests of Ilam province usin...
We consider, in a smooth bounded multiply connected domain D ⊂ R, the Ginzburg-Landau energy Eε(u) = 1 2 ∫ D { |∇u|2 + 1 2ε2 (1− |u|2)2 } subject to prescribed degree conditions on each component of ∂D. In general, minimal energy maps do not exist [4]. When D has a single hole, Berlyand and Rybalko [5] proved that for small ε local minimizers do exist. We extend the result in [5]: Eε(u) has, in...
One of the most prominent features on gravity and aeromagnetic maps of the United States is a series of major, generally linear anomalies that extend from central Kansas to Lake Superior and then turn southward into central Michigan (Figures 1, 2). This system of anomalies clearly reflects major geological features, and as such it must represent a very significant episode in the history of the ...
