the study area is a part of the sanandaj-sirjan metamorphic belt comprising low- to high-graderegional and contact metamorphic rocks that are intruded by various plutonic bodies. garnet crystals areabundant in pelitic schists, amphibole schists, migmatites, hornfelses and aplites. they are mostly almandinerich(xalm>60) pyralspite garnets and show dodecahedron, trapezohedron and mixed (dodecahed...
substitution at codon ser315 of katg gene, a reliable marker for isoniazid (inh) resistance and proliferate in spite of the loss of cell wall is called an l- form. unstable l- forms can convert to normal cells but stble l-forms can not.cell wall - deffective state may be induced spontaneously or through the action of an appropriate agent such as antibiotic interfering with the synthesis of cell...
وضعیت پتاسیم در خاکهای تحت کشت گندم و ارتباط آن با پتاسیم دانه در منطقه داراب، جنوب شرقی استان فارس
The status of soil K forms and its relationship with K content in wheat grain at harvest period may be important for nutrient fertility management. For this purpose, 40 surface (0-20 cm) and subsurface (20-40 cm) soil samples and also grain samples from wheat fields of Darab region were randomly sampled in 2014. Then physicochemical properties of the soils and the contents of soluble, exchangea...
In the long-term, wind erosion has considerable impact on rangelands. The aim of this study is to understand the changes of Hanitiyeh Rangelands located 30 kilometers east of Ahvaz and its function. Two transects, 42 meters in length, in wind gradient, patch and inter patch with 5 repeats that included shrub log complex, bush, grass, shrub, shrub-grass and bare open soil were measured. In addit...
this study was designed and conducted to find out if there is any significant relationship between iranian efl learners preferance for one of the three degrees of obtrusiveness in foreign language instruction (focus on form, forms and meaning) and their preferred experiential learing style. to collect the data two questionnaires were used. the first one on the degree of obtrusiveness and the se...
In this paper, we study generalized quadratic forms over a division algebra with involution of the first kind in characteristic two. For this, we associate to every generalized quadratic from a quadratic form on its underlying vector space. It is shown that this form determines the isotropy behavior and the isometry class of generalized quadratic forms.
Medulloblastoma (MB) is the most common pediatric brain cancer. Several important developmental pathways have been implicated in MB formation, but fewer therapeutic targets have been identified. To locate frequently overexpressed genes, we performed a comprehensive gene expression survey of MB. Our comparison of 20 primary tumors to normal cerebellum identified neuronatin (NNAT) as the most fre...
Adler, Howard I. (Oak Ridge National Laboratory, Oak Ridge, Tenn.), and Alice A. Hardigree. Growth and division of filamentous forms of Escherichia coli. J. Bacteriol. 90:223-226. 1965.-Cells of certain mutant strains of Escherichia coli grow into long multinucleate filaments after exposure to radiation. Deoxyribonucleic acid, ribonucleic acid, and protein synthesis proceed, but cytokinesis doe...
