Superconducting wires are widely used in fabricating magnetic coils in fusion reactors. In consideration of the stability of 11B against neutron irradiation and lower induced radio-activation properties, MgB2 superconductor with 11B serving as boron source is an alternative candidate to be used in fusion reactor with severe irradiation environment. In present work, a batch of monofilament isoto...

DFT calculations were applied to evaluate the electronic and magnetic properties of zigzag BC2Nnanotubes based on the 13C, 15N, and 11B NMR parameters and natural charge analysis. Weconsidered three types of zigzag nanotubes, ZZ-1, ZZ-2, and ZZ-3 (n, 0) with n = 8, 12, and 14. Theobtained results indicated the divisions of the electrostatic environments around C nuclei into a fewlayers, consist...

We investigated the enhanced production of nuclei formed via incomplete fusion (ICF) reactions near and above Coulomb barrier energies (5–8 MeV/A). The cross-sections evaporation residues in reactions—11B+124Sn, 10B+124Sn 11B+122Sn—were measured using off-line gamma-ray spectrometry. sum rule model (SRM) by Wilczyński et al. predicted cross-section values too low compared to our experimental re...

The targeted approach of protein kinases (PKs), as PKs are the main regulators cell survival and proliferation, has been a promising strategy for cancer treatments. Here we analyse potential quinoline-carboxamide derivatives four lines: MCF-7, CACO, HepG-2 HCT-116 anticancer agents. 3e, 4b, 11b 13d showed good anti-proliferative activities in comparison to reference standard Doxorubicin, agains...

the tumors in which odontogenic differentiation is fully expressed are the odontomas. odontomas are considered as hamartomas rather than a true neoplasm. these tumors are composed of enamel, dentine, cementum and pulp tissue. it is most commonly associated with the eruption of the teeth. they are usually discovered on routine radiographic examination. in exceptional cases, the odontoma erupts i...

In this study, the ion concentrations (K+, Na+, Ca2+, Mg2+, Cl?, SO42?, Br?, NO3?, and B3+) boron isotope compositions (?11B) of 34 halite brines samples from Neoproterozoic Salt Range Formation, Punjab, Pakistan were studied. Relation among B3+ vs. ?11B B3+, vs K+ observed, they indicated that these elements originate multiple sources end members identified as seawater, B desorption clays, met...

Low activation isotopic boron (11B) based magnesium diboride (Mg11B2) superconductors doped with biomass-derived activated carbon were synthesized using 11B and powder via solid-state reaction. The effect of doping on the lattice structure superconducting properties Mg11B2 bulks evaluated X-ray diffraction, high resolution transmission electron microscopy, scanning microscopy magnetization meas...

The distribution of acetylated alpha-tubulin in rat cerebellum was examined and compared with that of total alpha-tubulin and tyrosinated alpha-tubulin. From immunoperoxidase-stained vibratome sections of rat cerebellum it was found that acetylated alpha-tubulin, detectable with monoclonal 6-11B-1, was preferentially enriched in axons compared with dendrites. Parallel fiber axons, in particular...

Trimethylborane (1), triethylborane (2), 1,3-dimethyl-1-boracyclopentane (3), 1-methyl-1boracyclohexane (4), 9-methyland 9-ethyl-9-borabicyclo[3.1.1]nonane [5(Me) and 5(Et)], and 1boraadamantane (6) were studied by 11B and 13C NMR spectroscopy with respect to coupling constants 1J(13C,11B) and 1J(13C,13C). Results of DFT calculations at the B3LYP/6-311+g(d,p) level of theory show satisfactory a...

In humans, spironolactone and mespirenone are well known antimineralocorticoids without C-11b substituents. These compounds display antagonist properties by acting through the human androgen receptor (hAR). In contrast, we demonstrate here that synthetic mineralocorticoid antagonists bearing hydrophobic C-11b substituents and C-17g-lactone are potent hAR agonists in vitro. The three-dimensional...
