Wildlife is an important biological indicator of viability of ecosystems, therefore, understanding habitat requirements of species is essential for biodiversity conservation. Determining the suitability of habitats for wildlife is important for effective management and conservation of species. The brown bear (Ursus arctos), as the largest carnivorous mammal in Iran, is distributed in most fores...
Protective coal pillars in underground mining are technological losses the technology of extracting at Angren deposit. During mine operation, a significant part remains space. Extracting them is not possible with traditional energy-mechanical technologies. The paper considers new extraction -energy-heat unmanned brown energy from space spent fields. research results on experimental sites combus...

Background: Cryptosporidiosis is a zoonotic disease with public health importance, especially for individuals with weak immune system, such as children, elderly people and immune suppressed ones. Evaluation of the prevalence of Cryptosporidium in wild rodents such as wild brown rats could help to establish an epidemiological map of Cryptosporidiosis. The aim of the current study was to assess t...
b a ckground: the brown-banded cockroach, supella longipalpa is known as a carrier of pathogenic bacteria in urban environments, but its role is not well documented regarding the carriage of antibiotic-resistant pathogenic bacte- ria in iran. the aim of this study was to determine the resistance bacteria isolated from the brown-banded cockroach in ahvaz, south west of iran. m e t hods: totally ...
Data of four layers flocks (#31-34) from North Carolina Layer Performance and Management Test of the Department of Agriculture and Consumer Services were used in the meta-analysis to find if an increase in space allowance can affect egg production traits in white and brown layers. Effects of space allowance of 310 and 413 cm2/bird on layers performance were compared in this study. The increase ...

Field and laboratory investigations of tobacco plants were carried out to analyze the distribution Verticillium wilt caused by V. dahliae. dahliae is isolated from field Z (Tarkhai, Yarhussain region Swabi). Species Fusarium Actinomycetes detected in B (Shaheedan, Swabi), while no was these fields. identified based on its colony conidia morphology. The white, having oval spores septate mycelium...
We consider the evolution of neutron-star (ns), carbon-oxygen white-dwarf (co) binaries, using both the Bethe & Brown (1998) schematic analytic evolutions and the Portegies Zwart & Yungelson (1998) numerical population syntheses. The scenario in which the circular neutron-star, carbon-oxygen white-dwarf binaries (ns, co)c have gone through common envelope evolution is considered. In conventiona...
Pardosa pseudoannulata and Menochilus sexmaculatus are two predators of the brown planthopper (BPH, Nilaparvata lugens, Hemiptera: Delphacidae) in rice fields. The research aimed to determine predation competition model P. M. on different BPH densities. This study used a completely randomized design (CRD) factorially. first factor was difference predator species (P. pseudoannulata, sexmaculatus...
