the construct of self-efficacy has received increasing attention in research over the past two decades. many studies have been carried out 1.3 significance of the study this study has pedagogical implications since improving students’ self- efficacy and autonomy is important for promoting actual performance on classroom academic tasks. in academic settings, it has been shown that self-effi...
statement of problem: the bond strength between restorative material and tooth structure is so important for conduction of durable restoration. considering the recent attention to low shrinkage composite resins, evaluation of micro tensile bond strength of these materials would be valuable. objectives: to compare the microtensile bond strength of silorane composite resin (filtek p90) with the c...
the central purpose of this study was to conduct a case study about the role of self monitoring in teacher’s use of motivational strategies. furthermore it focused on how these strategies affected students’ motivational behavior. although many studies have been done to investigate teachers’ motivational strategies use (cheng & d?rnyei, 2007; d?rnyei & csizer, 1998; green, 2001, guilloteaux & d?...
Transposons are discrete segments of DNA that have the distinctive ability to move and replicate within genomes across the tree of life. 'Cut and paste' DNA transposition involves excision from a donor locus and reintegration into a new locus in the genome. We studied molecular events following the excision steps of two eukaryotic DNA transposons, Sleeping Beauty (SB) and piggyBac (PB) that are...
Various sequences within Tag1, the endogenous transposon of Arabidopsis, were examined to determine how Tag1 excision and expression are regulated. The 5' intron for the major 2.3-kb Tag1 transcript was found to be critical for the accumulation of Tag1 transcripts and for high rates of somatic excision. This was true for the autonomous element in cauliflower mosaic virus 35S-Tag1-beta-glucuroni...
this thesis is about the effect of self-confidence and educational motivation on oral translation quality.
abstract niklas luhmann was one of the prominent thinkers in the realm of sociology and the philosophy of social sciences. his approach was a systems approach. he classified the realm of reality and its entities into four groups that consisted of: machines, organisms, psychic systems, social systems. he belonged to the second wave of systemic thought and focused on the complexity and emergence ...
Accurate and effective positive marker excision is indispensable for the introduction of desired mutations into the plant genome via gene targeting (GT) using a positive/negative counter selection system. In mammals, the moth-derived piggyBac transposon system has been exploited successfully to eliminate a selectable marker from a GT locus without leaving a footprint. Here, we present evidence ...
the importance of writing as a complex skill in applied linguistics has drawn the attention of many researchers to evaluate textbooks in order to help learners gain self-sufficiency and autonomy in the field of language use and communication. investigations have shown that developments in textbooks evaluation can promote the quality of pedagogies and consequently the learning. this study attemp...
Ancient schwannomas rarely found in the central nervous system and ancient change in an intracranial schwannoma (intracranial portion of the trigeminal nerve) is extremely rare. A seventy-year man presented with headache of 3 months duration and one episode of generalized tonic-clonic seizures. Imaging findings were suggestive of left temporal high grade lesion. During surgery there was well...
