2001년 수집된 한국잔디 133계통들 중에서 우수한 계통들을 선발하기위하여 밀도(품질),<br/> 피복성, 녹색기간, 내병성, 출수유무(종자수) 등의 주요특성과 그 외 생육특성들이 조사되었다. 생육특성이 우수한 6계통이 선발되었으며 그 결과를 요약하면 다음과 같다.<br/> 수집된 133계통들 중에서 가장 녹색기간이긴 계통은 J01067으로 11월초까지 녹색도를 유지하였다. J01106 및 J01129 계통들은 엽폭이 각각 1.5mm 및 2mm 정도로 매우 좁으며, 밀도가 높고, 피복성도 좋은 것으로 나타났으며, 내병성도 강하였다. J01122 계통은 들잔디 계통들 중에서 유일하게 내병성이 강한 계통으로 선발되었다. J01128 계통은 엽폭이 3.2mm로 중엽에 속하였으며, 대비품종인 Sunburst 와 비슷하였다. 이 계통의 경우도J01106, J01129 계통들과 마찬가지로 밀도가 높고 내병성이 강한 것으로 나타났다.<br/> 수집된 133계통들의 형태적 분류를 위하여 5가지의 생육특성을 사용하여 크게 세가지 군집<br/> 으로 분류하였으며, 그 중에서 대비품종으로 사용된 6품종들과 선발된 우수 6계통의 분류는<br/> 다음과 같다. 제 1군집에 속하는 품종 및 계통은 Belare, Meyer, 안양중지(Anyang-jungji), J01067, J01112 등이 포함되었으며, 제 2군집으로는 S-94, J01105가 포함되었고, 제 3군집에는 Sunburst, 건희(Konhee), J01106, J01128, J01129 등이 포함되었다. Growth characteristics such as density(quality), covering speed, green period, disease resistance, heading existence(number of seeds) and other characteristics were examined for selection of superior lines among the 133 zoysiagrass lines collected in 2001. Six superior lines were selected and the results were summarized as follows.<br/> Superior line, J01067 was longest for green period among the 133 zoysiagrasses and stayed green until the beginning of November. Leaf width of J01106 and J01129 lines was very narrow as 1.5㎜ and 2㎜, respectively and superior for density(quality), covering speed and disease resistance. J01122 line was selected for strongest disease resistance among the lines of Zoysia japonica. Leaf width of J01128 was 3.2㎜ showing midium type and similar to standard cultivar, Sunburst. This line also showed higher density and strong disease resistance like J01106 and J01129.<br/> Five growth characteristics for morphological classification of 133 zoysiagrass lines<br/> was used and divided into 3 cluster groups. Of 133 lines, 6 standard cultivars and 6 superior lines were classified as follows. First cluster group contained Belare, Meyer, Anyang-jungji, J01067, J01122, and second group contained S-94 and J01105, and third group contained Sunburst, Konhee, J01106, J01128 and J01129.<br/> <br/>

Soil moisture content were 30%, 45% and 60% to maximum water-holding capacity for whole growth period. This experiment was carried out to study on the influence of soil moisture to growth and physiology of Turkish varieties. The results are summarized as follow ; a. Dry weight of Samsun and Zichna were-increased at 45% soil moisture content, but Smyrna and Xanthi at 60%. In every soil moisture treatmennt, there were significant difference between D plot and M, W plot but there were no significant difference between M plot and W plot. b. Percentage of dry matter of Smyrna was higher then those of the other varieties in the D plot and W plot. c. Leaf area was increased ill the Samsun of which process was slightly late. In every soil moisture treatment, M plot and W plot were higher than D plot. d. Dry weight per unit leaf area of Smyrna and Zichna were higher than that of Xanthi and Samsun. e. Percentage of dried up leaves was the W plot, and lower at the D and M plot. Smyrna was lower at M plot, Zichna at D and M plot, Xanthi at D plot, but Samsun was no difference among plots. f. In the number of harvested leaves, Smyrna was increased in order W>M>D. In the number of harvested leaves, Smyrna showed difference according to the soil moisture in order W>M>D plot, but Samsun and Zichna showed no difference among each treatments, Xanthi was higher in M plot than D and W plot. From those results, Smyrna showed the highest dry weight on account of the weight of leaf area and percentage of dry weight increased, it was decreased in order Zichna>Samsun Xanthi in the each soil moisture contents. Number of harvested leaves, dried up leaves, leaf area and number of harvested leaves but decreased, percentage of dry matter W treatment increased the number of total leaves, number of dried up leaves, leaf area, percentage of dried up leaves and percentage of dry matter. Yields were the lowest at D treated, there were no difference between M and W treatment. II.Influence of deficient or excessive supply of soil moisture at different growing stages.

The varieties used in this study were Samsun, Zichna and Xanthi. The results are summarized as follow; a. Dry leaf weight was decreased in order Zichna>Samsun>Xanthi, there were remakable difference among every variety. In each soil moisture content, weight of dry matter was increased by M and W treated at late stage after MW and MM treated at early and middle stage of growth DWM and MDM plot. Dry leaf weight was decreased at D plot more than M and W plot late stage after early stage was treated by MW and MM. Dry leaf weight was the highest at WWM treate, dthere were high significant difference between varieties and soil moisture contents. b.

<P>The degree of ferromagnetism of Ni-W<SUB>y</SUB> alloys decreases as W-content y increases. Both the saturation magnetization <I>M</I> <SUB>sat</SUB> and Curie temperature <I>T</I> <SUB>c</SUB> decrease linearly with W-content y, and both <I>M</I> <SUB>sat</SUB> and <I>T</I> <SUB>c</SUB> go to zero at critical concentration of y<SUB>c</SUB> ~9.50 at.% W. To compare with Ni-W alloys, the magnetic properties of a series of both as-rolled (non-textured) and annealed (biaxially textured) [Ni<SUB>97at.%</SUB>-W<SUB>3at.%</SUB>]<SUB>100-x</SUB>-Cu<SUB>x</SUB> alloy tapes with compositions x = 0, 1, 3, 5, and 7 at.%, were studied. Characterization methods included XRD analyses to investigate the biaxial texturing of the annealed [Ni-W]-Cu alloy tapes and studies of the magnetization for both as-rolled and annealed [Ni-W]-Cu alloy tapes. Both the isothermal mass magnetizations <I>M</I>(<I>H</I>) of a series of samples at different fixed temperatures and <I>M</I>(<I>T</I>) in fixed field, were measured. The effect of Cu addition on both the saturation magnetization and Curie temperature T<SUB>c</SUB> of the Ni<SUB>97at.%</SUB>-W<SUB>3at.%</SUB> alloy was investigated.</P>

OH (1720 MHz) MASERS: A MULTIWAVELENGTH STUDY OF THE INTERACTION BETWEEN THE W51C SUPERNOVA REMNANT AND THE W51B STAR FORMING REGION

Brogan, C. L.,Goss, W. M.,Hunter, T. R.,Richards, A. M. S.,Chandler, C. J.,Lazendic, J. S.,Koo, B.-C.,Hoffman, I. M.,Claussen, M. J. IOP Publishing 2013 The Astrophysical journal Vol.771 No.2

<P>We present a comprehensive view of the W51B H II region complex and the W51C supernova remnant (SNR) using new radio observations from the VLA, VLBA, MERLIN, JCMT, and CSO along with archival data from Spitzer, ROSAT, ASCA, and Chandra. Our VLA data include the first lambda = 400 cm (74 MHz) continuum image of W51 at high resolution (88 ''). The 400 cm image shows non-thermal emission surrounding the G49.2-0.3 H II region, and a compact source of non-thermal emission (W51B_NT) coincident with the previously-identified OH (1720 MHz) maser spots, non-thermal 21 and 90 cm emission, and a hard X-ray source. W51B_NT falls within the region of high likelihood for the position of TeV gamma-ray emission. Using the VLBA, three OH (1720 MHz) maser spots are detected in the vicinity of W51B_NT with sizes of 60-300 AU and Zeeman effect magnetic field strengths of 1.5-2.2 mG. The multiwavelength data demonstrate that the northern end of the W51B HII region complex has been partly enveloped by the advancing W51C SNR and this interaction explains the presence of W51B_NT and the OH masers. This interaction also appears in the thermal molecular gas which partially encircles W51B_NT and exhibits narrow pre-shock (Delta v similar to 5 km s(-1)) and broad post-shock (Delta v similar to 20 km s(-1)) velocity components. RADEX radiative transfer modeling of these two components yield physical conditions consistent with the passage of a non-dissociative C-type shock. Confirmation of the W51B/W51C interaction provides additional evidence in favor of this region being one of the best candidates for hadronic particle acceleration known thus far.</P>

An experimental study of dynamic track tension for high mobility tracked vehicle is investigated and compared to multibody dynamic simulation model. This research focuses on a heavy military tracked vehicle which has sophisticated suspension and rubber bushed track systems in computer model of the track tension. In order to obtain accurate dynamic track tension of track subsystems, each track link is modeled as a body which has six degrees of freedom. A compliant bushing element is used to connect track links. Various virtual proving ground models of Chang-Won proving ground are developed to observe dynamic changes of the track tension. The obtained empirical results of the dynamic track tension are comparcd against the simulation studies. <r.B.7]~%<>1 : Tracked Vehicle{;>~￡,"j-"J), Trnck Link(;>~￡"83), Dynamic Trnck Tension(%"'1 ;>~￡"J-;;:j), Compliant Bushing (%<;! .!J!.>-J), DTJS("J-;;:j ~;;<.j A16 ',iJ)
