スマートフォンを活用した海象情報のリアルタイム収集用の漂流ブイを試作し，実海域において動作確認試験を実施した．スマートフォンの内部機能と外部拡張機能を組み合わせて，GPSによる測位と風向風速を計測し，携帯電話網を介してリアルタイムにデータを遠隔地に伝送するシステムを構築した．実海域試験では，通信性能及び海象データを評価し，実用化できる可能性が大きいことを示した．
We present a facile method to integrate NaYF4∶Yb,Er upconversion nanoparticles with Au nanoparticles for constructing NaYF4∶Yb,Er@SiO2@Au composite nanostructures,in which a silica layer on NaYF4∶Yb,Er nanoparticles to make them water-stable and acts as an interface for Au decoration.The green and red emissions of the…
Resumo: 5E-(feniletenil)benzofuroxano (5PhEBfx) foi descrito como um excelente candidato a frmaco anti-chagsico. Entretanto, sua biodisponibilidade oral foi afetada pelo processo de cristalizao. Duas amostras exibindo varivel atividade in vivo foram investigadas: um p fino amarelo (5PhEBfx-Y) e agulhas laranjas (5PhEB…
Ultrasound irradiation was used for anchoring silver nanoparticles with an average size from 10 to 50 nm onto the surface of acrylonitrile-butadiene-styrene (ABS) sheets 1 mm thick. The sonochemical reduction was car- ried out under argon at room temperature. Silver nano- particles were obtained and deposited on the A…
木材や農産廃棄物に代表される植物バイオマスの主要構成成分であるセルロース系多糖類や，糖類および植物性油脂を出発原料として微生物合成ないし化学合成される生分解性脂肪族ポリステルは，既存の石油系合成高分子にはない種々の特長を有している．代表例として微生物産生ポリ(ヒドロキシアルカン酸)における100%光学，そして天然セルロースが形成する幅数ナノメートルのナノファイバー構造が挙げられる．さらに，高強度・高耐熱性バイオマスプラスチックとして，各種の農産廃棄物から抽出される芳香族ヒドロキシ酸を重縮合した芳香族ポリエステルが注目を集めている．本報では，これらのバイオマスプラスチックに関して，基礎的特性である溶解性，レオロジー特性，熱的特性の検…
食道がん術後に上室性不整脈が出現した8症例を対象に，塩酸ピルジカイニド0.75 mg/kgを10分間で静脈内投与した。投与直前～投与開始後8時間に血漿中濃度測定を行い，2-compartment modelを用いて薬物動態学的変化を検討した。食道がん術後患者の最高血中濃度は2.07±0.59μg/mlであり，これは健常人より有意に高い値であった。またα相半減期の著明な延長と，定常状態分布容積および末梢コンパートメント容積の有意な減少が認められた。以上より，食道がん術後患者では塩酸ピルジカイニドの薬物動態が大きく変化しており，通常用量の単回静脈内投与で抗不整脈作用のための至適血中濃度を超えることが明らかとなった。また，効果が認められ…
Aquatic bacteria were isolated from eutrophic lake in Khon Kaen Province, Thailand. One hundred and eighty eight bacterial isolates were screened for anticyanobacterial activity against the toxic cyanobacterium Microcystis aeruginosa by well-diffusion and liquid-culture methods. The result showed that five isolates (K…
A vertical type high speed twin roll caster is able to cast an aluminum alloy strip directly from a molten metal that is poured between the rotating rolls. However defects such as small cracks and unsound thickness distribution of the cast strip occur at faster roll speed. They are related to the contact condition of…
L’attività svolta nelle precedenti annualità ha permesso di acquisire le informazioni di base sulla reazione di metanazione, essendo stata studiata la reazione dal punto di vista termodinamico ed avendo condotto una prima serie di prove sperimentali. La applicazione di questa reazione in un impianto, anche solo in sca…
Исследованы кристаллические и расплавные включения в крупных (до 2 см) бипирамидальных фенокристаллах кварца из дацитов миоценового возраста в районе AuAg месторождения Рошия Монтана, Румыния. Использованы методы гомогенизации включений и анализ кристаллических включений и стекол более 40 расплавных включений с помощ…
The fatigue strength of the sintered and super rapid induction heated and quenched (SRIQ) compact made of the 0.6 mass% Mo - 0.2 mass% Mn prealloyed steel powder has been investigated. As the effective case depth in the SRIQ material decreased, fatigue strength increased, and reached to 400 MPa equivalent to two times…
Our recent research on damage mechanisms of artificial nodules in dielectric multilayers will be reviewed. The focus is on the influence of electric-field distributions on thermomechanical damage of nodules.
Вычисление энтальпий образования/смешения бинарных сплавов является важной задачей. До сих пор, однако, ни в рамках широко известной теории Миедемы, ни с привлечением методов первопринципных подходов не проводились системные теоретические расчеты энтальпий смешения бинарных сплавов элементов b-подгрупп Периодической С…
