緑化壁面に利用されるヤブコウジ，オタフクナンテン，プミラ，テイカカズラ，ヤブラン，へデラ，ローズマリーを対象に，植物の炭素固定量を簡易に推定する方法について検討した。植物を植栽し，成長に伴う植物の地際から先端までの長さ，葉面積，乾燥重量の変化を測定した。いずれの植物でも植物の地際から先端までの長さと乾燥重量，および葉面積と乾燥重量の間には有意な正の相関関係が見られた。植物体の炭素濃度はどの植物も概ね400～450 g kg-1であった。これらから，植物の長さからおよその炭素固定量を推定可能であった。

本研究ではアルギン酸ナトリウムと枯草菌から構成されるバイオ補修材の自己・自律治癒性状に与える種々の影響要因について検討を行った。本研究により、フライアッシュ混和によるセメント水和物量の相違、中性化の有無による細孔構造の変状により、補修後のひび割れ近傍の水酸化カルシウムの分布状況は変動し自己・自律治癒性状に影響することがわかった。特に、中性化後のフライアッシュ配合では水酸化カルシウムの拡散による移動が抑制される傾向が一定程度認められる。また透水試験の結果より、基準とした普通モルタル供試体と比較してフライアッシュ供試体では中性化後にひび割れ閉塞効果が低下することが示唆される。

In this paper, dynamic response analysis of a Floating Offshore Wind Turbine (FOWT) with Spar-type floating foundation is presented. The FOWT mounts a 100kW down-wind turbine, and is grid-connected. It was launched at sea on 9th June 2012, and moored on 11th for the purpose of the demonstration experiment. During the experiment, the FOWT was attacked by severe typhoon events twice. Among them, Sanba (international designation: 1216) was the strongest tropical cyclone worldwide in 2012. The central atmospheric pressure was 940 hPa when it was close to the FOWT, and the maximum significant wave height of 9.5m was recorded at the site. In this paper, the dynamic responses of the platform motion, the stresses at the tower sections and the chain tensions during the typhoon event, Sanba (1216), have been analyzed, and compared with the measured data. Through the comparison, validation of the numerical simulation tool (Adams with SparDyn developed by the authors) has been made.

Solid-state polymerization of phenylbutadiyne derivatives with o-nitro, m-nitro or p-nitro group was investigated. All monomers in bulk crystals could be thermally polymerized to become black suggesting formation of extended π-conjugation system. However, no regular polydiacetylene structures were confirmed by the structural analysis. Nanocrystals of the m-nitro derivative were prepared, and the different polymerization behavior compared with in the bulk crystals was observed.
