the crisis of identity in jhumpa lahiris fiction: interpreter of maladies and the namesake
شکل گیری هویت(identity) مقوله مهمی در ادبیات پراکنده مردم(diasporan literature) می باشد. آثار جومپا لاهیری(jhumpa lahiri) ، نویسنده هندی آمریکایی، در سالهای اخیر تحسین منتقدین را به خود معطوف کرده است. وی در این آثار زندگی مهاجران و تلاش آنان برای پیدا کردن جایگاهشان در یک فرهنگ بیگانه را به تصویر کشیده است. این تجربه همواره با احساساتی نظیر دلتنگی برای گذشته، بیگانگی و دوری همراه است. با این ح...
15 صفحه اولImmobilization of Aspergillus beta-glucosidase on chitosan.
beta-Glucosidase of Aspergillus phoenicis QM 329 was immobilized on chitosan, using the bifunctional agent glutaraldehyde. The most active preparation based on the amount of support contained a 1:2.5 enzyme-to-chitosan ratio (wt/wt). However, the specific activity of the bound enzyme decreased from 10 to 1% with increasing enzyme-to-chitosan ratio. Compared with free beta-glucosidase, the immob...
متن کاملBiochemical properties of a beta-xylosidase from Clostridium cellulolyticum.
A 43-kDa beta-xylosidase from Clostridium cellulolyticum was purified to homogeneity. The enzyme releases xylose from p-nitrophenylxylose and xylodextrins with a degree of polymerization ranging between 2 and 5. The N-terminal amino acid sequence of the enzyme showed homologies with three other bacterial beta-xylosidases. By proton nuclear magnetic resonance spectroscopy, the enzyme was found t...
متن کاملPurification and properties of an inducible beta-glucosidase of yeast.
In the past decade considerable advances have been achieved in the study of induced enzyme biosynthesis in microorganisms. A comparison of three of the better studied systems, P-galactosidase in Escherichia coli (l), penicillinase in Bacillus cereus (2), and oc-glucosidase in Xaccharomyces cerevisiae (3) indicates that there are a number of differences in these inductions. In order to compare f...
متن کاملSignificance of the detection of beta-galactosidase and of beta-xylosidase in the taxonomic study of the genus Haemophilus.
A total of 314 strains of Haemophilus, isolated from clinical samples, were studied for the production of beta-galactosidase and beta-xylosidase. None of the H. influenzae strains studied (9 beta-lactamase positive strains and 129 beta-lactamase negative strains) possessed these enzymes. Both enzymes were almost constantly observed among strains of H. paraphrophilus (10 strains studied) and of ...
