향끽미종 연초의 한국, 그리이스간 생태 비교 연구 (I) 재배환경 및 생육특성
김용옥,류명현,정형진,조명조,Symeonidis, George D 한국연초학회 1987 한국연초학회지 Vol.9 No.1
KA 101 and Xanthi-Basma were cultivated in Korea and Greece to compare the respective responses to environment and cultivation method on their growth characteristics and some properties of harvested leaves during 1984 and 1985. The contents of clay, calcium, organic matter and pH were higher in the soil of greece than that of Korea. Sunshine hours and precipitation in Greece during harvest and curing season were 8.6 hours per day and 53.3mm compared to that of 3.8 hours per day and 320mm in Korea, respectively. The plant height, leaf size and yield decreased, and days to flower was shorter 8-11 days in greek grown plants. The dehydration and curing process in Greece was linear and rapid due to the constant daily change of temperature and relative humidity with dry weather during curing season during curing season. But those process in Korea was variable and tardy due to rainy weather. Cured leaf ratio increased with upper stalk leaves in Greece but it was rather lower at top stalk position in Korea. The harvested green leaf cultivated in Greece showed higher contents of petroleum ether extract, total nitrogen and nicotine, but lower contents of reducing sugar and lower ratio of protein nitrogen to total nitrogen than in Korea.

Evolution of dust temperature of galaxies through cosmic time as seen by <i>Herschel</i><sup>★</sup>
Hwang, H. S.,Elbaz, D.,Magdis, G.,Daddi, E.,Symeonidis, M.,Altieri, B.,Amblard, A.,Andreani, P.,Arumugam, V.,Auld, R.,Aussel, H.,Babbedge, T.,Berta, S.,Blain, A.,Bock, J.,Bongiovanni, A.,Boselli, A.,B Blackwell Publishing Ltd 2010 MONTHLY NOTICES- ROYAL ASTRONOMICAL SOCIETY Vol.409 No.1
<P>ABSTRACT</P><P>We study the dust properties of galaxies in the redshift range 0.1 ≲<I>z</I>≲ 2.8 observed by the <I>Herschel Space Observatory</I> in the field of the Great Observatories Origins Deep Survey-North as part of the PACS Extragalactic Probe (PEP) and <I>Herschel</I> Multi-tiered Extragalactic Survey (HerMES) key programmes. Infrared (IR) luminosity (<I>L</I><SUB>IR</SUB>) and dust temperature (<I>T</I><SUB>dust</SUB>) of galaxies are derived from the spectral energy distribution fit of the far-IR (FIR) flux densities obtained with the PACS and SPIRE instruments onboard <I>Herschel</I>. As a reference sample, we also obtain IR luminosities and dust temperatures of local galaxies at <I>z</I> < 0.1 using <I>AKARI</I> and <I>IRAS</I> data in the field of the Sloan Digital Sky Survey. We compare the <I>L</I><SUB>IR</SUB>–<I>T</I><SUB>dust</SUB> relation between the two samples and find that the median <I>T</I><SUB>dust</SUB> of <I>Herschel</I>-selected galaxies at <I>z</I>≳ 0.5 with <I>L</I><SUB>IR</SUB>≳ 5 × 10<SUP>10</SUP> L<SUB>⊙</SUB> appears to be 2–5 K colder than that of <I>AKARI</I>-selected local galaxies with similar luminosities, and the dispersion in <I>T</I><SUB>dust</SUB> for high-<I>z</I> galaxies increases with <I>L</I><SUB>IR</SUB> due to the existence of cold galaxies that are not seen among local galaxies. We show that this large dispersion of the <I>L</I><SUB>IR</SUB>−<I>T</I><SUB>dust</SUB> relation can bridge the gap between local star-forming galaxies and high-<I>z</I> submillimetre galaxies (SMGs). We also find that three SMGs with very low <I>T</I><SUB>dust</SUB> (≲20 K) covered in this study have close neighbouring sources with similar 24-μm brightness, which could lead to an overestimation of FIR/(sub)millimetre fluxes of the SMGs.</P>
