if the precise implementation of the principle of proportion and:balance between the violation and the penalty as well as the other dimensions could be considered as a stick yard for the imptementation of justice any lack of preciseness in carrying out such principle would not indeed be much too far from injustice . naturally ,if it would be imagined that the objective of balance between...
Breast cancer is a common malignancy in women all over the world and novel therapeutic approaches are required for the treatment of patients who become refractory to conventional therapies. Thyroid cancer is being treated successfully with radioiodine since many years. The iodide is transported inside the thyroid epithelial cell via sodium iodide symporter (NIS) which is a trans-membrane protei...
Arsenic (As) is a ubiquitously present environmental carcinogen that enters into the human food chain through rice grains. In our previous research, the application of thiourea (TU; a non-physiological thiol based ROS scavenger) has been demonstrated to enhance salt and UV stress tolerance as well as the crop yield under field conditions. These effects were associated with the ability of TU to ...
building on previous studies on intellectual features and learners’ grammar learning, the present study aimed at investigating whether intelligence criterion had any impact on efl learners’ english grammar learning across two intelligence levels. in the current study, the participants were divided into two experimental and control groups by administration of raven i.q. test. this led to the for...
this study investigated how group formation method, namely student-selected vs. teacher-assigned, influences the results of the community model of teaching creative writing; i.e., group dynamics and group outcome (the quality of performance). the study adopted an experimental comparison group and microgenetic research design to observe the change process over a relatively short period of time. ...
Two structural genes for the Thermus thermophilus elongation factor Tu (tuf) were identified by cross-hybridization with the tufA gene from E. coli. The sequence of one of these tuf genes, localized on a 6.6 kb Bam HI fragment, was determined and confirmed by partial protein sequencing of an authentic elongation factor Tu from T.thermophilus HB8. Expression of this tuf gene in E. coli minicells...
In most prokaryotes Asn-tRNA and Gln-tRNA are formed by amidation of aspartate and glutamate mischarged onto tRNA and tRNA, respectively. Coexistence in the organism of mischarged Asp-tRNA and Glu-tRNA and the homologous Asn-tRNA and Gln-tRNA does not, however, lead to erroneous incorporation of Asp and Glu into proteins, since EF-Tu discriminates the misacylated tRNAs from the correctly charge...
the purpose of the present study was to investigate the effect of task-based instruction of vocabulary on the receptive and oral productive acquisition of english vocabulary and compare the results with those obtained from the traditional method. the method and procedure applied in this study was as follows: after the implementation of opt, a group of sixty female students were chosen. the stu...
this study purported to compare and contrast the use of self-mention and evidentials as two mtadiscourse features in opinion columns of persian and english newspapers. the theoretical basis of this study is the idea that metadiscourse features vary across cultural boundaries. for this purpose, 150 persian and 150 english opinion columns were collected based on three factors of topic, audience a...
In most prokaryotes Asn-tRNA(Asn) and Gln-tRNA(Gln) are formed by amidation of aspartate and glutamate mischarged onto tRNA(Asn) and tRNA(Gln), respectively. Coexistence in the organism of mischarged Asp-tRNA(Asn) and Glu-tRNA(Gln) and the homologous Asn-tRNA(Asn) and Gln-tRNA(Gln) does not, however, lead to erroneous incorporation of Asp and Glu into proteins, since EF-Tu discriminates the mis...
