Background and Purpose: Inhalation of hardwood dust may produce a range of adverse health effects in the upper and lower respiratory system, including asthma, along with Sino-nasal cancer and nasopharyngeal cancer. This study was carried out to evaluate personal exposure to wood dust among workers in chipboard and furniture production saloons in Neka Choob factory, Iran. Materials a...
damage caused by freezing can be the result of differences in cellular processes, including changes in membrane properties, interactions between macromolecular and enzymatic reactions. in this experiment, total soluble solids (tss) and relative water content of the reproductive buds of cultivars “j. h. hale”, “elberta,” “redhaven, ” “sorkh sefid mashhad” and “amsden” peaches, along with nectari...
The Alborz mountain range in northern Iran is part of the active and seismic Alpide belt, where assessing hazards crucial due to region’s history large instrumental earthquakes destructive background. Moment rate estimation, which quantifies tectonic activity, offers a novel approach understanding energy potential regions. In this study, regional perspective employed investigate maximum horizon...
abstract because of the many geopolitical, geo economical and geo strategically potentials and communicational capabilities of eco region, members can expand the convergence and the integration in base of this organization that have important impact on members development and expanding peace in international and regional level. based on quality analyzing of library findings and experts interv...
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
The production of new and compatible cultivars to different environments is one of the most important goals for the breeders. The crossing new cultivars and the selection of superior genotypes for desirable traits among their offspring is a method that has always been used by breeders. 28 genotypes obtained from the crossing of a 7 × 7 one-way diallel experiment consisting of seven parents (Alv...
The order Saprolegniales includes pathogenic species of aquatic and terrestrial plants and aquatic animals including fish. These straminipilous fungi play an important role as a decomposing component which participates in the destruction processes of organic substrates and self-cleaning biological processes in freshwater ecosystems. In this study, samples of brown decayed twigs, leaves, woods a...
investigating species diversity and richness is essential for defining conservation priorities. in addition, determining landscape parameters influencing species diversity and richness is important for selecting and designing parks and protected areas. kohgiluyeh & boyer ahmad province is a mountainous region, comprises hills, mounds, forests and plains. this vast province has high species dive...
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
