in current work a comprehensive mechanism based on intermediate radical termination theory is assumed for raft polymerization of styrene over cumyl dithiobenzoate as raft agent. rate constants for addition (ka) and fragmentation reactions (kf) are set to 6×106 and 5×104 respectively, which lead to an equilibrium constant value of k = ka/kf = 1.2 x 102. moment equations method was used to model ...
in the new age, in regard to human success in education in the globalizing world, one can consider english proficiency and individual differences as two important issues. in efl settings, reading skill plays an important role in education. it seems that using multiple intelligences theory in efl classes which values individual differences by tapping different intelligences, can be rewarding. as...
this research study aimed to investigate the relationship between field-dependence/independence cognitive style and vocabulary learning strategies among iranian efl learners. ninety participants majoring in english translation at arak university were chosen. the participants were classified into two groups of field-dependent and independent based on the results of group embedded figure test (ge...
abstract this study aimed at investigating the effect of bilingual teaching of cognate words (persian-english) on iranian upper intermediate efl learners’ knowledge of lexical development. for this purpose,100 subjects participated in this study out of which 40 learners were selected for this study and they were assigned into two groups, control and experimental. cross-language cognates (wor...
the present study was conducted to investigate the effect of implicit focus on form through input flooding and the effect of noticing, explicit focus on form on linguistic accuracy. to fulfill the purpose of the study, 86 iranian pre-intermediate efl learners of one of the language institutes were chosen by means of administering ket as the homogeneity test. these learners were pretested throug...
While politicians in Washington, who have already authorized trillions of funds for businesses the past 3 years, been arguing over allocating state and local governments, there a number suggestions that stimulus packages potentially benefit certain states at expense to others. The arguments primarily appear come down politics – “red,” Republican-led versus “blue,” Democratically-led states. ins...
RESULTS: Flow cytometry demonstrated that genetic loss of scleraxis among mesenchymal cells significantly reduced the presence of macrophages (F4/80+) and neutrophils (Cd11b+Ly6G+) at the injury site within 48 hours after injury. The presence of PDGFRa+ mesenchymal cells was also significantly reduced based on both flow cytometry and histologic analysis. These findings were confirmed with cipro...
Introduction: Radiation Induced Bystander Effect (RIBE) which cause radiation effects in non-irradiated cells, has challenged the principle according to which radiation traversal through the nucleus of a cell is necessary for producing biological responses. What is the mechanism of this phenomenon? To have a better understanding of this rather ambiguous concept substantial number of original ...
Family I soluble pyrophosphatases (PPases) exhibit appreciable ATPase activity in the presence of a number of transition metal ions, but not the physiological cofactor Mg(2+). The results of the present study reveal a strong correlation between the catalytic efficiency of three family I PPases (from Saccharomyces cerevisiae, Escherichia coli and rat liver) and one family II PPase (from Streptoc...
Sponsored search is one of the most successful applications of economic mechanisms in real life. A crucial issue is the modeling of the user behavior to provide the best targeting of ads to each user. Experimental studies show that the click through rate of an ad is dramatically affected by both its position and the other displayed ads. However, these externalities rise severe currently open co...
