هدف پژوهش حاضر، بررسی شگردهای تعامل متن و تصویر در کتاب "هیچ هیچ هیچانه" است. به این منظور، اثر یادشده که شامل 52 شعر از هفت شاعر نام‌آشنای کودک ایران است، مورد بررسی قرار گرفت. روش پژوهش تحلیل محتوای قیاسی- استقرایی و واحد تحلیل، هر شعر به‌همراه قاب تصویری آن است. این بررسی به دو پرسش بنیادی پاسخ می‌دهد: 1- آیا شعرها و تصویرهای این کتاب هیچانی هستند؟ 2- شگردهای ارتباطی شعرها و تصویرهای این کتا...
OBJECTIVES To determine if the TEM beta-lactamases of Haemophilus influenzae are TEM-1 or derivatives thereof and associated exclusively with the overlapping Pa/Pb promoters. METHODS Single nucleotide specific PCR was used to discriminate the polymorphic nucleotides at positions 32 and 317 of the bla(TEM) genes of a collection of TEM-positive strains. RESULTS All bla(TEM) genes were found t...
چکیده: موضوع اصلی این تحقیق، بررسی تصویرهای سوررئالیستی در هشت کتاب سهراب سپهری است. برای این مقصود نگارندهمی خواهد اثبات کند که تصاویر شعری سپهری تا چه اندازه سوررئالیستی است. ابتدا در مبحث تصاویر سوررئالیستی، ضمن بحث در موردمشخّصه هایی چون: نگارش خودکار، خواب و رویا، تعطیلکردن عقل و ... بیان می کند که سپهریارائه دهنده ینمونه هایتمام عیار تصویرهای سوررئالیستی است. پس از آن در بخش ارتباط تصویره...
bla(TEM-1) expression results in penicillin resistance, whereas expression of many bla(TEM-1) descendants, called extended-spectrum beta-lactamases (ESBLs), results simultaneously in resistance to penicillins and extended-spectrum cephalosporins. Despite the expanded resistance phenotypes conferred by many ESBLs, bla(TEM-1) is still the most abundant bla(TEM) allele in many microbial population...
A new natural TEM derivative, named TEM-87, was identified in a Proteus mirabilis isolate from an Italian hospital. Compared to TEM-1, TEM-87 contains the following mutations: E104K, R164C, and M182T. Kinetic analysis of TEM-87 revealed extended-spectrum activity against oxyimino cephalosporins (preferentially ceftazidime) and aztreonam. Expression of blaTEM-87 in Escherichia coli decreased the...
Angiogenesis plays a key role in tumor growth and cancer progression. TIE-2-expressing monocytes (TEM) have been reported to critically account for tumor vascularization and growth in mouse tumor experimental models, but the molecular basis of their pro-angiogenic activity are largely unknown. Moreover, differences in the pro-angiogenic activity between blood circulating and tumor infiltrated T...
A new natural TEM-2 derivative, named TEM-72, was identified in a Proteus mirabilis strain and in a Morganella morganii strain isolated in Italy in 1999. Compared to TEM-1, TEM-72 contains the following amino acid substitutions: Q39K, M182T, G238S, and E240K. Kinetic analysis showed that TEM-72 exhibits an extended-spectrum activity, including activity against oxyimino-cephalosporins and aztreo...
use of zinc and iron oxide are common in the desulfurization process from natural gas. in thisresearch, after determinations of the size and specifications through tem and xrd for each of the metaloxides, two different size ratios were used, 0.66 for zinc oxide and 0.142 for iron oxide. further, absorption of sulfur compounds in gas (hydrogen sulfide (h2s), carbonyl sulfide (cos), methyl mercap...
Enterobacter aerogenes clinical isolate LOR was resistant to penicillins and ceftazidime but susceptible to cefuroxime, cephalothin, cefoxitin, cefotaxime, ceftriaxone, and cefepime. PCR and cloning experiments from this strain identified a novel TEM-type beta-lactamase (TEM-121) differing by five amino acid substitutions from beta-lactamase TEM-2 (Glu104Lys, Arg164Ser, Ala237Thr, Glu240Lys, an...
Eighty-five extended-spectrum beta-lactamase-producing Enterobacteriaceae from a Slovak hospital have been studied. SHV-2a was predominant, but other variants have been detected, namely, SHV-5, SHV-12, TEM-12, TEM-15, and TEM-132, which differed from TEM-1 by amino acid substitutions R164H, E240K, and I173V and had kinetic properties similar to those of TEM-28.
