synthesis and dna interaction studies of new cobalt (ii) complexes containing different dinitrogen aaromatic ligands with calf thymus dna using different spectroscopy methods
در این مطالعه بر هم کنش این چهار کمپلکس با dna تیموس گوساله توسط روش های اسپکتروفتومتری، فلوریمتری، دو رنگ نمائی دورانی، و ویسکوزیمتری بررسی شدند تا اثر استخلاف های متیل بر روی لیگاندهای فنانترولین بررسی گردد.
Subject Guides: Two Different Libraries, Two Different Approaches
The libraries at both Wichita State University and Butler Community College recently implemented new content management systems to create and manage library subject guides. These systems allow library staff to create online resources for instruction and library information quickly, and with no coding knowledge required. Both libraries chose a different option from many content management system...
متن کاملMagnesium pemoline: Effects on the learning and retention of a conditioned avoidance response by rats
Thirty-two albino male rat Ss were randomly assigned to four groups which were trained to perform a conditioned avoidance response to a criterion of acquisition. They were tested for retention at 24 hand 72 h. In acquisition, three of the four groups were given MgPe while a control group was given a placebo. After 24 h, two groups were drug-treated and two were placebo-treated. After 72 h, one ...
متن کاملPoint-contact Spectroscopy of Magnesium Diboride with Different Counter-electrodes
We report on tunneling and Andreev-reflection conductance spectra of 39 K superconducting magnesium diboride, obtained with Pb and Au counter-electrodes. Two distinct steps at close to 2.7 and 7.1 meV appear in a low-resistance metallic-type Au-MgB2 junction characteristic, whereas a tunneling-like spectrum measured for the same junction, annealed by the application of dc current, exhibits only...
متن کاملControllable Synthesis of Magnesium Oxysulfate Nanowires with Different Morphologies
One-dimensional magnesium oxysulfate 5Mg(OH)2 MgSO4 3H2O (abbreviated as 513MOS) with high aspect ratio has attracted much attention because of its distinctive properties from those of the conventional bulk materials. 513MOS nanowires with different morphologies were formed by varying the mixing ways of MgSO4 7H2O and NH4OH solutions at room temperature followed by hydrothermal treatment of the...
