pistachio green stink bug, acrosternum hegeeri, due to its inflicting damages on crop quantity and quality, is of a great economical importance in pistachio production. on the other hand, a knowledge of digestive enzymes, is quite indispensable in the study and application of new pest management technologies. results of studeies have shown that midgut in this insect is divided into four section...
the impact of three different fabaceous host plants including cowpea (vigna unguiculata), chickpea (cicer arietinum), and mung bean (vigna radiata) seeds was investigated using biochemical approaches on possible changes of gut proteolytic activity of the cowpea weevil, callosobruchus maculatus at 30±1˚c and 70±5% rh and a photoperiod of 8:16 (l:d). results revealed that ph of 4-5 and 9 was opti...
objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
سن سبز پسته، acrosternum heegeri، با ایجاد خسارت کمّی و کیفی، اهمیت اقتصادی زیادی در تولید محصول پسته دارد. آگاهی از وضعیت آنزیم های گوارشی، به منظور بکارگیری تکنیکهای نوین، در کنترل آفت ضروری است. روده میانی در این حشره به چهار قسمت (1m تا 4m) تقسیم می شود که از لحاظ مرفولوژیک متفاوتند و مقدار ph هریک از سمت جلو به سمت عقب (1m تا 4m) به ترتیب بصورت 1/0±04/6، 13/0±22/6، 1/0±6 و 12/0±1/6 بدست آمد...
a novel ultra wideband microstrip bandpass filter using radial stub loaded resonator and interdigital coupled lines is presented in this paper. the radial stub loaded resonator and decagonal patch form a resonator named m to create tuneable multiple notches in the passband for suppression wlan interference. to realize sharp roll-off, two adjustable transmission nulls are located at the lower an...

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
BACKGROUND Celiac disease is a T cell mediated-inflammatory enteropathy caused by the ingestion of gluten in genetically predisposed individuals carrying HLA-DQ2 or HLA-DQ8. The immunogenic gliadin epitopes, containing multiple glutamine and proline residues, are largely resistant to degradation by gastric and intestinal proteases. Salivary microorganisms however exhibit glutamine endoprotease ...
in this thesis we will present three topics. we define approximate fixed points in fuzzy normed spaces. also we obtain some necessary and sufficient conditions on the existence of? -fixed points for ? > 0. at the continue some results about approximate fixed points for a class of non-expansive maps on g-metric spaces are obtained and we define approximate fixed points in partial metric spa...
The chemical synthesis of N-alpha-benzyloxycarbonyl-L-lysine p-nitroanilide (Z-Lys-pNA) is described in detail. The pH-dependence of the catalytic parameters kcat,' Km and kcat./Km for the papain-catalysed hydrolysis of Z-Lys-pNA are determined. kcat. and Km are pH-independent between pH 5 and pH 7.42, but the pH-dependence of kcat./Km is bell-shaped, decreasing at high and low pH values with p...
