in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
abstract translation has become a cultural act which plays a significant role in human life. with the emergence of functional translation theories, and skopos theory in particular, translation has been considered as a purposeful, interpersonal and intercultural activity which is produced for particular recipients and directed by a specific purpose. this purpose determines the translatio...
Abiotic stresses such as salinity and contamination individually have a negative effect on the soil enzyme activities, whereas addition of organic matter to soil can alleviate the negative impacts of stresses on the enzyme activity. However, the combined effects of these stresses (multiple stresses) on soil biochemical conditions and the role of organic matter addition in these interactions are...

the purpose of this study was to investigate the impact of blended learning and multimedia softwares on iranian efl students vocabulary learning. in addition, the present study tried to examine the extent to which multimedia softwares can be applied into efl classes in iran. it also attempted to find out students attitudes toward using these softwares. to this end, 87 iranian efl learners at el...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
This study analyzed the inhibition activity of Swietenia mahagoni seeds extract on α-glucosidase and α-amylase enzymes inhibition assays. Swietenia mahagoni seeds were extracted by using Supercritical Carbon Dioxide (SC-CO2) extraction at pressures of 20- 30 MPa and temperatures of 40- 60°C. The oil yields obtained were analyzed with α- glucosidase and α- amylase enzymes inhibition assays. A...
Proper preservation of transgenes and transgenic materials is important for wider use of transgenic technology in plants. Here, we report stable preservation and faithful expression of a transgene via artificial seed technology in alfalfa. DNA constructs containing the uid reporter gene coding for β-glucuronidase (GUS) driven by a 35S promoter or a tCUP promoter were introduced into alfalfa via...
Alfalfa seeds and seedlings contain an enzyme that catalyzes a reaction with the 13- and 9-hydroperoxides of linoleic acid to form 13-hydroxy-10-oxo-trans-octadecenoic acid and 9-hydroxy-12-oxo-trans-10-octadecenoic acid, respectively. When commercial lipoxygenase is used to generate the hydroperoxides, the above acids appear in about 2:1 proportions, respectively. The products of the action of...
Asparaginase was extracted from plant parts of Pisum sativum subspp. Jof collected from a field crop. Asparaginase activity was detected in seeds, stems and leaves extracts. Enzyme activity was higher in seeds extracts (30.0 U/ml) compared with leaves extracts (26.4 U/ml) and stems extracts (16.1 U/ml), respectively. Optimum conditions for the activity of crude asparaginase extracted from plant...
to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...
