<P>Multifunctional catalysts are of great interest in catalysis because their multiple types of catalytic or functional groups can cooperatively promote catalytic transformations better than their constituents do individually. Herein we report a new synthetic route involving the surface functionalization of nanoporous silica with a rationally designed and synthesized dihydrosilane (3-aminopropylmethylsilane) that leads to the introduction of catalytically active grafted organoamine as well as single metal atoms and ultrasmall Pd or Ag-doped Pd nanoparticles via on-site reduction of metal ions. The resulting nanomaterials serve as highly effective bifunctional dehydrogenative catalysts for generation of H-2 from formic acid.</P>
PATIAL DISTRIBUTION OF STAR FORMATION ACTIVITY ON NGC 253 BY FIR AND RADIO EMISSION LINES
Takahashi, H.,Matsuo, H.,Nakanishi, K. The Korean Astronomical Society 2012 天文學論叢 Vol.27 No.4
The aim of this research is to reveal the spatial distribution of the star formation activity of nearby galaxies by comparing CO molecular emission lines with the large area observation in far-infrared (FIR) lines. We report the imaging observations of NGC 253 by FIR forbidden lines via FIS-FTS and CO molecular lines from low to high excitation levels with ASTE, which are good tracers of star forming regions or photo-dissociation regions, especially spiral galaxies, in order to derive the information of the physical conditions of the ambient interstellar radiation fields. The combination of spatially resolved FIR and sub-mm data leads to the star formation efficiency within galaxy. The ratio between the FIR luminosity and molecular gas mass, $L_{FIR}/M_{H_2}$, is expected to be proportional to the number of stars formed in the galaxy per unit molecular gas mass and time. Moreover the FIR line ux shows current star formation activity directly. Furthermore these can be systematic and statistical data for star formation history and evolution of spiral galaxies.

The effects of salt and bicarbonate solution on overall meat quality in beef biceps femoris muscle were investigated with the application of chilling and freezing conditions. Muscles were injected to a target of 120% of original meat weight with a solution containing 1.2 M sodium chloride, 0.25 M sodium bicarbonate and 0.1% ascorbic acid (pH 7.2). Half of the meat samples, considered as chill treatment and chill control, were stored at $4^{\circ}C$ up to five days; while the other half, frozen treatment and frozen control, were kept in a freezer at $-20^{\circ}C$ for seven days. Compared with untreated control, treated meats had higher water holding capacity (p<0.05), lower drip loss (p<0.05) and lower shear force (p<0.07) with higher overall acceptability (p<0.05) in sensory evaluation. Morphological observations demonstrated smooth and gummy meat surface due to the solubilization of myofibrillar proteins and the distortion of connective tissue in treated raw meats; and in the case of cooked meat, treatment caused the fragmentation of myofibrils, which might be responsible for a lower shear value in salt-bicarbonate treated beef biceps femoris muscle.
The distribution of Δ<sup>14</sup>C in Korea from 2010 to 2013

<P><B>Abstract</B></P> <P>Δ<SUP>14</SUP>C values of leaves of a deciduous tree record to those of atmospheric CO<SUB>2</SUB> within error and were used to map out Δ<SUP>14</SUP>C distribution in Korea. We collected ginkgo (<I>Ginkgo biloba Linnaeus</I>, a deciduous tree) leaf samples in mid-June to early July from 2009 to 2013 in Korea to obtain the regional distribution of Δ<SUP>14</SUP>C. Commonly CO<SUB>2</SUB> emitted from fossil fuel consumption dilutes atmospheric <SUP>14</SUP>C, while operations and accidents at nuclear power plants can increase it. The distribution maps of Δ<SUP>14</SUP>C from 2010 to 2013 in Korea shows that Δ<SUP>14</SUP>C values in the northwestern and southeastern parts of Korea are lower than those of the other parts of Korea, which is consistent with the population and industry patterns. Decrease rates of annually averaged Δ<SUP>14</SUP>C values in Korea over the study period are larger than those of Pt. Barrow, Alaska, USA (71.3°N, 156.5°W), so the difference between them and those of Pt. Barrow, Alaska, USA became larger annually. This may be due to the increase in fossil fuel consumption in Korea and China. The decrease rate between 2010 and 2011 was smaller than in other years. This could be the effect of the Fukushima power plant accident which occurred in March 11, 2011, but further study is needed to clarify it.</P>

Faithful transmission of genetic information depends on accurate chromosome segregation as cells exit from mitosis, and errors in chromosomal segregation are catastrophic and may lead to aneuploidy which is the hallmark of cancer. In eukaryotes, an elaborate molecular control system ensures proper orchestration of events at mitotic exit. Phosphorylation of specific tyrosyl residues is a major control mechanism for cellular proliferation and the activities of protein tyrosine kinases and phosphatases must be integrated. Although mitotic kinases are well characterized, phosphatases involved in mitosis remain largely elusive. Here we identify a novel variant of mouse protein tyrosine phosphatase containing domain 1 (Ptpcd1), that we named Ptpcd2. Ptpcd1 is a Cdc14 related centrosomal phosphatase. Our newly identified Ptpcd2 shared a significant homology to yeast Cdc14p (34.1%) and other Cdc14 family of phosphatases. By subcellular fractionation Ptpcd2 was found to be enriched in the cytoplasm and nuclear pellets with catalytic phosphatase activity. By means of immunofluorescence, Ptpcd2 was spatiotemporally regulated in a cell cycle dependent manner with cytoplasmic abundance during mitosis, followed by nuclear localization during interphase. Overexpression of Ptpcd2 induced mitotic exit with decreased levels of some mitotic markers. Moreover, Ptpcd2 failed to colocalize with the centrosomal marker ${\gamma}$-tubulin, suggesting it as a non-centrosomal protein. Taken together, Ptpcd2 phosphatase appears a non-centrosomal variant of Ptpcd1 with probable mitotic functions. The identification of this new phosphatase suggests the existence of an interacting phosphatase network that controls mammalian mitosis and provides new drug targets for anticancer modalities.
