We extend to you a warm and sunny Aloha in celebration of the 23 rd American Peptide Symposium and the 6 th International Symposium. The meeting theme, Peptides Across the Pacific, embraced the spirit of the scientific and social program. Peptides Across the Pacific encompassed the important role that peptide science…
以Zn（NO3）2·6H2O和Ni（NO3）2·6H2O为原料，采用柠檬酸溶胶-凝胶法合成了NiO-ZnO系列复合物。利用x射线衍射仪（XRD）、扫描电镜（SEM）、透射电镜（TEN）等对系列复合物的物相及形貌进行表征，利用静态配气法对其气敏性能进行测试。研究了煅烧温度对复合物乙醇敏感特性的影响。结果表明，600℃下煅烧得到的NiO．ZnO复合物对乙醇在较低的工作温度125℃下具有良好的敏感性能，如对50ppm乙醇的灵敏度为29．8，响应和恢复时间很短仅为8s和14s，且对于汽油、丙酮、乙醚等其余7种测试气体有较高的选择性，经1个月的稳定性测试该复合物对乙醇敏感特性基本保持不变。
Установлено влияние различных факторов (анодной плотности тока, состава электролита, электродного материала) на выход по току анодной реакции образования ионов Сr(VI) на Pt и композиционных TiOx/PtOy при электролизе растворов, содержащих ионы Cr3+. Показано, что значения выходов по току Сr(VI) на TiOx/PtOy уменьшаются…
substations. In addition, power transformer outages have a considerable economic impact on the operation of an electrical network. The most important parameters governing a transformer's life expectancy is the hot-spot temperature (HST) value and loss of life. Here in this paper by using graphical user interface (GUI)…
In recent years, along with the development and diffusion of light sources for illumination and display using light-emitting diodes (LEDs) or electro-luminescence (EL), how to evaluate the performance of phosphors used as materials in these sources has become a big issue. Quantum efficiency is a particularly important…
В затменно-двойной системе Y Cam, вторичная компонента которой заполняет свою полость Роша, а главная компонента является звездой типа Sct, изучено поведение со временем орбитального периода системы и периода пульсаций главной компоненты. Наблюдения моментов минимумов затменно-двойной системы охватывают 120 лет. В теч…
Two different topologies of three phase Unified Power Quality Conditioner (UPQC) namely 3P3W/ 3P4W UPQC are analyzed. For better performance of UPQC, DC link voltage have to be maintained. If it is energized through solar photovoltaics, a modified UPQC structure employing capacitor midpoint (dual capacitor) is employe…
Rules for PWR plant pipe wall thinning management were formulated by the Japan Society of Mechanical Engineers in 2006. Since then thinning management of Japanese PWR plants has been carried out based on this rule. Pipe wall thinning phenomena to be dealt with in this rule have been identified in many piping component…
The goal of this paper is to show the role technologies used in silk manufacturing played in the development of high quality silk production.In 1878, Kichiroji Tase and his family began producing raw silk through mechanical means in order to improve quality, but the early stages involved a great amount of trial and er…
層状構造を持つ無機イオン交換体を触媒担体として用いることで，活性種を層間へ均一に導入することができる1)。この方法を用いてわれわれが合成した様々な「層間触媒」は “Intercalation Catalysts” として国際的にも認識されるようになった2)。これらの無機化合物の結晶構造や化学的性質を効果的に利用することで，(1)触媒活性種の均一分散と触媒活性の向上，(2)反応空間制御と分子認識性の発現，(3)活性種の立体構造制御と分子認識性の向上，(4)触媒反応補助機能，(5)活性種の安定化などの特長を見いだしてきた。本論文では，われわれが合成して調べた触媒挙動の具体例を取り上げて，層間触媒の特徴を説明する。

A microstructure analysis along the trench depth direction of Cu wires as a function of the purity of plating materials was carried out using electron backscattering diffraction (EBSD) analysis combined with advanced CMP technique. The Cu wire plated with high purity plating materials (6N-electrolyte and 8N-anode) was…
Polymer solar cells (PSCs) have been one of the most promising replacement energy to fossil fuels. In recent years, since inverted PSCs with perfect stability have been reported, how to improve efficiency becomes the key issue of PSCs technology commercialization. Nowadays, many low-bandgap polymers were synthesized a…
本研究は，消波ブロック被覆堤を対象として，モンテカルロシミュレーションによる消波工のライフサイクルコスト(LCC)の算定において，高波発生回数が及ぼす影響を検討したものである．LCCとして初期建設費と供用期間の補修費を計上し，高波発生回数を年1回とする場合と，波浪観測資料にもとづく統計的特性を考慮して与える場合の2通りの計算を行った．日本沿岸の4地点での高波資料を解析した結果，年間の高波発生回数はポアソン分布で近似できることが示され，LCCの算定においてポアソン乱数で高波発生回数を与えた．結果として，LCCを最小とする消波ブロック径が高波発生回数の与え方によって異なったのは1地点のみであったが，補修費の変動性については差異が生じ，…

We have investigated the narrow gap filling by liquid epoxy resins containing silica particles at the volume fractions of 0.30, 0.40, and 0.49. The penetration of these liquid resin composites into a narrow gap between two parallel glass plates was observed. Addition of silane coupling agents reduced the filling time…
