the effect of in planta tiba and proline on in vitro seedlings and cell culture of sugar beet was investigated. sterilized seeds were grown in vitro on ½ strength ms medium supplemented with 0 or 3 mg/l tiba. calli obtained on young leaves cultured on ms medium containing 1 mg/l bap, were used for the intiation of cell suspension cultures using ms basal composition supplemented with 0 or 50 m m...
abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
today, information technology and computers are indispensable tools of any profession and translation technologies have become an indispensable part of translator’s workstation. with the increasing demands for high productivity and speed as well as consistency and with the rise of new demands for translation and localization, it is necessary for translators to be familiar with market demands an...
background: ferula gummosa boiss. is a medicinal and economical plant belonging to apiaceae family. it is a native herb of iran and is in serious danger of extinction. objective: gamma irradiation is an environmental stress and can consider as a new tool to change the content of secondary metabolites in medicinal plants. the effect of gamma irradiation on phenolic content and radical scavenging...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
چکیده توان بالقوه تجاری سلولازها و کاربردهای گوناگون آن ها در بسیاری از صنایع انگیزه ای قوی برای تحقیق در این زمینه طی چند دهه گذشته بوده است. با توجه به کاربردهای فراوان این آنزیم در صنایع غذایی? در این پژوهش تصمیم به جداسازی ریزسازواره های تولید کننده سلولاز از خاک درختان انار، انگور، خرمالو و گردو حیاط دانشکده کشاورزی تربیت مدرس، گرفته شد. در این بین خاک درخت خرمالو به دلیل دارا بودن تعداد ...
An efficient variety-independent method for producing transgenic eggplants (Solanum melongena L.) via Agrobacterium tumefaciens-mediated genetic transformation was developed. Two weeks old cotyledon explants were transformed by co-cultivation with Agrobacterium tumefaciens strain LBA4404 harboring a binary vector pVDH65 carrying the reporter gene β-glucuronidase intron (GUS-INT) and the marker ...
