This research was conducted to analyze the hardness, microstructural morphology, and crystallography of MgB2 compound in form a SS 304-sheathed superconducting wire. wire with 304 outer sheath manufactured using an ex-situ rolling process. The results Vickers hardness test load 0.3 N showed value 355.1 HV. observations SEM-EDS (scanning electron microscopy-energy dispersive spectroscopy) agglom...

in the present study, an ultrafine grained (ufg) 304l stainless steel with the average grain size of 300 nm was produced by a combination of cold rolling and annealing. weldability of the ufg sample was studied by nd: yag laser welding under different welding conditions. taguchi experimental design was used to optimize the effect of frequency, welding time, laser current and laser pulse duratio...

The VERITAS collaboration has observed the high-frequency-peaked BL Lac object 1ES 1218+304 using an array of several imaging Cherenkov telescopes located at the Fred Lawrence Whipple Observatory in Southern Arizona. A gamma-ray signal was detected with high significance for the observations taken during several months in the 2006-2007 observing season. Here we present the detection of 1ES 1218...

Chitinase A of Streptomyces cyaneus SP-27 or chitinase I of Bacillus circulans KA-304 showed the protoplast-forming activity when combined with alpha-1,3-glucanase of B. circulans KA-304. The gene of chitinase A was cloned. It consisted of 903 nucleotides encoding 301 amino acid residues, including a putative signal peptide (35 amino acid residues). The deduced N-terminal moiety of chitinase A ...

The gonadotropin-releasing hormone (GnRH) receptor in catfish differs from its mammalian counterparts in showing a very low affinity for the hypothalamic GnRH form [i.e. catfish GnRH (cfGnRH)] and a very high affinity for the highly conserved mesencephalic GnRH, chicken GnRH-II (cGnRH-II). In the present study we investigated the molecular interactions between ligand and receptor involved in de...

1ES 1218+304 is among a group of several TeV blazars that exhibit surprisingly hard energy spectra given their redshifts. The VERITAS collaboration has carried out an intensive observing campaign of 1ES 1218+304 in early 2009 to characterize the emission properties of one of these hard-spectra distant blazars in more detail. While hard-spectra TeV blazars are most promising for unveiling putati...
