mard-abad calc-alkaline granite formed along the margin of active pull-apart or intra-continental plates, and it is post-collision granite type. granophyric, perthitic and myrmekitic are main textures that could form from crystallization of hypersolvus source magma, which occurred under water vapor pressure of approximately 2 kb. during this study the temperature of formation of these granites ...

the enhanced dispersion of organophilic layered silicates improves the mechanical properties of polymer/ silicate composites. in this work, a hybrid filler system consisting of cloisite 15a organoclay (oc) and carbon black (cb) was used to improve the properties of the tire tread compounds. the physical and mechanical properties of compounds were assessed by measurement of their cure properties...

paracobitis rhadinaea , a member of the family nemacheiliidae, originally described by regan in 1906 from sistan basin, is poorely known by the rare materials. the inadequately studied species is redescribed on the base of freshly collected materials. the species differs from all other paracobitis species by combination of the following characters: stout and elongated body; large size, up to 28...

oil pollutions are widespread environmental pollutants. most of the studies have been focused on the biodegradation of these pollutions. unfortunately, the information on the microflore of the polluted regions especially for microalgae is limited. in this research, we have focused on masjed soleiman; one of the most oil polluted cities in iran. soil and water samples were collected from differ...

the aim of this study was to examine the possible morphological and morphometric changes resulting from vitrification of embryos at the cleavage stage. in this study, 30 mice early-cleavage embryos at different stages of cleavage, resulting from in vitro fertilization (ivf) techniques, were examined before and after vitrification. digital images were taken from embryos before and after vitrific...

geographical, morphological and taxonomic status of pistacia khinjuk stocks ex stocks in iranwas revised. a total of 181 accessions (herbarium materials or specifically collected for this study) wereexamined geographically and morphologically. the chromosome number of 2n = 24, revealed among 15accessions studied, was taken as evidence to lump the variability observed in p. khinjuk as one taxono...

abstractalthough the biokinetics, metabolism, and chemical toxicity of uranium are well known, until recently little attention was paid to the potential toxic effects of uranium on reproduction and development in mammals. in recent years, it has been shown that uranium is a developmental toxicant when given orally or subcutaneously (sc) to mice. decreased fertility, embryo/fetal toxicity includ...

A current challenging topic in mathematical morphology is the construction of locally adaptive operators; i.e., structuring functions are dependent on the input image itself at each position. Development of spatially-variant filtering is well established in the theory and practice of Gaussian filtering. The aim of the first part of the paper is to study how to generalize these convolutionbased ...

__________________________________________________________________________ Existing vehicle license plate identification and recognition systems are potent for either their accuracy or speed but not a combination of both. The algorithm proposed in this dissertation attempts to achieve this fine balance between the accuracy and speed that such a system must posses. The mathematical morphology op...
