this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...
The aim of the study was to analyze the influence of oven thermal processing of Cosmos caudatus on the total polyphenolic content (TPC) and antioxidant capacity (DPPH) of two different solvent extracts (80% methanol, and 80% ethanol). Sonication was used to extract bioactive compounds from this herb. The results showed that the optimised conditions for the oven drying method for 80% methanol an...
The rise of gas-sensing applications and markets has led to microwave sensors associated polymer-based sensitive materials gaining a lot attention, as they offer the possibility target large variety gases (as polymers can be easily functionalised) at ultra-low power wirelessly (which is major concern in Internet Things). A two-channel microstrip sensor with one resonator coated 1,2 epoxybutane-...
Background : Apples have been known as nutritious and natural medicines. The aim of this study was to determine the amounts of nutrients compounds of golden and red delicious apples produced in Lorestan, Iran. Materials and Methods: Apple cultivars were harvested from different locations throughout Lorestan province in September 2008. The samples were dried at 80 º C for two days. The dry mate...
in this thesis, a new optically active poly(amide-imide) (pai) was synthesized by the indirect polycondensation reaction of the l-phenylalanine based diacid chloride and 4,4?-diaminodiphenylether in the presence of triethylamine in n-methyl-2-pyrrolidone. the formation of pai was confirmed by ftir, 1h nmr and elemental analysis. in next step, the surface of titanium dioxide (tio2) nanoparticles...
the purpose of this study is to investigate the relationships between teachers’ immediacy behaviors and iranian students’ willingness to talk in english classes. analysis of the results from willingness to talk scale represents a relatively high level of willingness to talk in english classrooms among iranian language learners. the total mean score of students’ willingness to talk was 66.3 ou...
in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
This paper reports the successful pregnancy in rats with only 10-20% of ovarian tissue. Sprague-Dawley female rats of breeding age were divided into five groups: group 1 (completely ovariectomized), the ovaries from both the sides of the rats were removed completely; group 2 (partially ovariectomized, 80-90% of the ovary of each side was removed leaving the remaining tissue in place; group 3 (o...
PURPOSE To evaluate the current model of small bowel resection and intestinal transplantation in pigs. METHODS Forty two Large White pigs were distributed in five groups: G1(n=6), G2(n=6) and G3(n=6) were submitted to 80%,100% and 100% plus right colon resection respectively and G4(n=7) and G5(n=5) to 100% SBR plus IT without and with immunosuppression based on Tacrolimus and Mycophenolic aci...
In order to examine the impact of pure and mixed planting on the production of grasses and also the biological control of weeds an experiment was conducted in the research farm of Alashtar city of Lorestan province between the years 1391 and 1392. This experiment within the design of complete random blocks (RCBD) with 6 protections which included 100:0 (rouph pea pure planting) 0:100 (pure plan...
