in [u. dempwolff, on extensions of elementary abelian groups of order $2^{5}$ by $gl(5,2)$, textit{rend. sem. mat. univ. padova}, textbf{48} (1972), 359 - 364.] dempwolff proved the existence of a group of the form $2^{5}{^{cdot}}gl(5,2)$ (a non split extension of the elementary abelian group $2^{5}$ by the general linear group $gl(5,2)$). this group is the second l...
A method is described as an alternative to the use of nucleoside pre-functionalized supports for DNA synthesis. The procedure should allow the generation of 3'-OH terminal moieties of any natural or modified DNA fragment using a single derivatized solid support material. The method utilizes 1-O-(4,4' dimethoxytrityl)-2- O-succinoyl-3-N-allyloxycarbonylpropane immobilized on amino-propyl CPG fol...
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. ...
A reaction cassette has been designed for the highly sensitive detection of the making and breaking of chemical bonds. The system is envisioned as a companion device to be used in the search for antibody and other novel catalysts. The cassette also may have important clinical applications in the design of diagnostic reagents. In its fully encoded format, this methodology is capable of both dete...
this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
