We introduce a new polarimeter installed on the high-resolution fiber-fed echelle spectrograph (called BOES) of 1.8-m telescope at Bohyunsan Optical Astronomy Observatory, Korea. The instrument is intended to measure stellar magnetic fields with (R $\sim$ 60000) spectropolarimetric observations intrinsic polarization in spectral lines. In this paper we describe spectropolarimeter and present test longitudinal some well-studied F-B main sequence stars (m_v < 8.8^m). results demonstrate...
β-Ketoacyl acyl carrier protein synthase (KAS) III, the most divergent member of condensing enzyme family, is a key catalyst in bacterial fatty acid biosynthesis and, thus, an attractive target for novel antibiotics. Here, we perform docking studies between Enterococcus faecalis KAS III (efKAS III) and one flavanone 11 hydroxyflavanones with hydroxy groups at various positions. The MIC values these flavanones E. vancomycin-resistant (VREF) were measured, binding affinities to efKAS...
Abstract The ignition, oxidation, and pyrolysis chemistry of methyl propyl ether (MPE) was probed experimentally at several different conditions, a comprehensive chemical kinetic model constructed to help understand the observations, with many key parameters computed using quantum transition state theory. Experiments were carried out in shock tube measuring time variation CO concentrations, flow product rapid compression machine (RCM) ignition delay times. detailed reaction mechanism...
The conversion yield of d-psicose from d-fructose by a 3-epimerase Agrobacterium tumefaciens increased with increasing molar ratios borate to fructose, up ratio 0.6. formation the psicose-borate complex was result higher binding affinity for psicose than fructose. formed did not participate in reaction, acting instead as if product had been removed. Thus, more fructose converted order restore equilibrium. maximum about twofold that obtained without and occurred at 0.6 Above this ratio,...
Abstract Arenicin‐1 (AR‐1) is a novel antimicrobial peptide that was isolated from coelomocytes of the marine polychaeta lugworm Arenicola marina and shown to contain single disulfide bond between Cys3 Cys20, forming an 18‐residue ring [Ovchinnikova, T. V. et al., FEBS Lett 2004, 577, 209–214]. To determine role this bond, we synthesized AR‐1 (RWCVYAYVRVRGVLVRYRRCW) its linear derivative, arenicin‐1‐S (AR‐1‐S: RWSVYAYVRVRGVLVRYRRSW). Activity assays revealed AR‐1‐S somewhat less active...
Advanced combustion modes have drawn much attention from researchers due to increasingly strict emissions regulations. Partially premixed compression ignition (PCCI) creates a partially charge inside the cylinder before occurs. As result, NOx and particulate matter (PM) can be reduced simultaneously relative those of conventional diesel combustion. The basic operating mechanism PCCI is prolong time period for mixing fuel–air mixture by separating end injection start Three different fuels,...
HP (2-20), a 19-residue peptide derived from the N-terminus of Helicobacter pylori ribosomal protein L1, has antimicrobial activity but is not cytotoxic to human erythrocytes. We synthesized several analogues investigate effects substitutions on structure and activity. Replacement Gln16 Asp18 with tryptophan [anal-3 (analogue-3)] caused dramatic increase in lytic activities against bacteria fungi. By contrast, decrease amphiphilicity by replacement Phe5 or Leu11 serine was accompanied...
The critical compression ratio (CCR) criterion (defined as the minimum at which fuel shows initial signs of autoignition) was examined for various gasoline surrogate fuels in a motored engine. This investigation builds on concept CCR is good indicator fuel's autoignition characteristics, to study compositional effects with increasing intake manifold pressure. blends consisted binary and ternary mixtures n-heptane and/or iso-octane, interest. These interest were higher octane components;...
