Two experiments conducted on laying hens, aged 50 and 52 weeks, were carried out to evaluate the effect of dietary Mg and its relationship to the Ca : NPP (non-phytate phosphorus) ratio using a various grain-size of limestone. The Ca : NPP ratio in each experiment was 12.8 and 18, respectively. Two Mg levels were evalued in the first (1.56 and 4.0 g/kg) and the second experiment (1.52 and 4.0 g...
Background: Electron-capture reaction rates on medium-heavy nuclei are an important ingredient for modeling the late evolution of stars that become core-collapse or thermonuclear supernovae. The estimation of these rates requires the knowledge of Gamow-Teller strength distributions in the β+ direction. Astrophysical models rely on electron-capture rate tables largely based on theoretical models...
Biotic stress may operate in concert with physical environmental conditions to limit or facilitate invasion processes while altering competitive interactions between invaders and native species. Here, we examine how endolithic parasitism of an invasive and an indigenous mussel species acts in synergy with abiotic conditions of the habitat. Our results show that the invasive Mytilus galloprovinc...
The strength for a flexible shell of vehicle pneumatic spring during movement relative to rail track has been studied in the paper. calculation carried out using finite element method implemented SolidWorks software environment. For this purpose, 3D drawings balloon-type have reproduced. A specific feature design is that distance between upper and lower bottoms static conditions unchanged – tha...
We present results from recent time-of-flight nuclear mass measurements at the National Superconducting Cyclotron Laboratory at Michigan State University. We report the first mass measurements of ^{48}Ar and ^{49}Ar and find atomic mass excesses of -22.28(31) MeV and -17.8(1.1) MeV, respectively. These masses provide strong evidence for the closed shell nature of neutron number N=28 in argon,...
we report herein the development of a highly sensitive colorimetric method for the detection of 4-hydroxy-2-mercapto-6-methylpyrimidine (mtu) which acts as an anti-thyroid drug utilizing citrate capped gold nanoparticles (au-nps). this thiol-containing molecule exhibits intriguing affinity with au-nps. the reactivity involves the displacement of the citrate shell by the thiolate shell followed ...
The effect of eggshell particles on the mechanical properties of epichlorohydrin crosslinked chitosan/eggshell composites had been studied. The content of eggshell particles in each composites was varied from 2.5 to 13.4% (w/w). The tensile strength was 60% improved, compared to the control chitosan. The composite with 13.4% (w/w) content of eggshell particles showed the optimum tensile strengt...
