until now many studies have been done over recent decades throughout the world to show the right age to start english. in iran, research is still at an early stage in terms of evaluating teachers’ beliefs about teaching children english. the problem of at what age to start teaching english and how to teach english to elementary school children has not been solved neither in this country nor els...
Haloalkane dehalogenase converts haloalkanes to their corresponding alcohols and halides. The reaction mechanism involves the formation of a covalent alkyl-enzyme complex which is hydrolyzed by water. The active site is a hydrophobic cavity buried between the main domain and the cap domain of the enzyme. The enzyme has a broad substrate specificity, but the kcat values of the enzyme for the bes...
power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
The manipulation of redox potential in secretory pathway by thiol reducing agents can be a strategy to improve the production levels of disulfide-bonded proteins including recombinant antibodies. Here we have studied the influence of cysteamine on viability and the production level of IgG4 in Sp2.0 cells. For this purpose, the recombinant Sp2.0 cells producing an anti CD33 IgG4, were subjected ...

a novel silver (ag) nanocomposite electrode was proposed that fabricated from metal nanostructures and ionic liquids. the combined application of unique properties of nanomaterials and ionic liquids in the design of this ag nanocomposite results in electrodes with interesting advantages compared to the conventional metal disk electrode. in the first part of this thesis, the elecrocatalytic eff...
Abstract Allelopathy is a phenomenon by which plants positively or negatively affect neighboring releasing allelopathic compounds. These allelochemicals are secondary metabolites found in different concentrations shoots, roots, leaves, flowers, and even pollen grains. Allelochemicals have potential as natural bioherbicides for controlling weeds when applied the form of extracts through intercro...
OBJECTIVE To investigate the effect of long-term exposure to glucosamine or mannosamine on the catabolism of aggrecan by explant cultures of bovine articular cartilage maintained in the presence of retinoic acid. DESIGN The kinetics of loss of 35S-labeled and total aggrecan from explant cultures of bovine articular cartilage maintained in the presence of 1 micro M retinoic acid and exposed to...
