食品に含まれるタンパク質は，栄養源としてだけではなく多彩な食品物性・機能を具備している．食品加工において，タンパク質のような高分子化合物が示す特徴的な物性や機能の‘源’は加工時に形成されるナノスケールの凝集体構造にあり，その構造に依存した分子間相互作用により動的性質が発揮されている．したがって，食品の高分子化合物のナノスケールの凝集体構造とその凝集体間の相互作用を解明することにより，食品物性の発現機構が明らかになると考えられる．しかし，不溶性である高分子凝集体のナノ構造は分析手法が限られているため，食品科学分野では未開の領域として取り残されてきた．一方，材料科学の分野では，ソフトマターのナノ構造の解明に固体だけでなく溶液中の粒子構…
Vacuum arc electrical breakdowns cause problems in many appliances operating in high electric field, such as the Compact Linear Collider (CLIC), a proposed next-generation particle accelerator in CERN. The breakdown phenomenon is not well-understood despite decades of research. Diffusive mass transport in metallic sur…
The full-width at half-maximum (FWHM) was measured on the tooth surfaces of a pair of power transmission gears by the X-ray diffraction method during a gear surface fatigue endurance test to investigate the progress of the surface fatigue. The results showed that the tooth surface damage occurred when the normalized F…
The novel cationic hydrogels based on N-isopropylacrylamide (NIPAAm) and N-(2-vinyloxyethyl)-N-(2-cyanoethyl) amine (VOECEA) were synthesized for the first time by radical copolymerization. The composition of copolymers were determined by using IR spectroscopy.
The influence of the strain rate sensitivity of the yield stress on multiple impact of three identical spheres were examined by FEM analysis in this study. Firstly the influence on colliding behavior were investigated. Then, the influence on macro-characteristics such as maximum contact force, maximum deformation, coe…
The effects of fuel injection timing and coolant temperature on soot and particulate emissions at stoichiometric mixture condition under heating mode were examined in a single cylinder spark ignition direct injection gasoline engine. Single injection was employed and the start of fuel injection timing was adjusted in…
スポット溶接によりすきまを形成して，0.86 kmol･m−3NaCl水溶液噴霧，乾燥，湿潤過程からなる塩乾湿繰り返し試験を行い，フェライト系ステンレス鋼のすきま部腐食特性に及ぼす合金元素の影響を調査した．18Cr1Mo鋼へのNi添加が最大腐食深さの低減に最も有効であった．Moも有効な元素であったが，高Cr化は効果がなかった．酸性高NaCl溶液中における臨界不働態化電流密度の低減と最不働態化pHの低下に対してNiは最も有効に作用した．Niのアノード溶解抑制と再不働態化促進の効果により，すきま部の最大腐食深さが顕著に低下したと考えられた．
Industrial processes for production of metals and alloys by metallurgical and electrochemical methods generate a lot of heat due to irreversible losses. The waste heat should be used to generate electricity. Commercial thermoelectric generators based on semiconductor materials have limited power efficiency. Alternativ…
Over previous years, an increasing effort has been devoted to the use of nano particles and cellulose obtained from natural resources as reinforcing elements for the composites with polymeric matrices. Bacterial cellulose (BC) can be also used in composite materials, usually combined with both organic and inorganic pa…

Currently, biodegradable plastics capable of soil decomposition are attracting attention, but they have drawbacks such as low strength. Therefore, it is necessary to reinforce strength by using biodegradable fibers such as natural fibers. However, there are dispersions in strength of natural fibers. In this paper, we…
Creep-fatigue damage in high-temperature components gradually proceeds at stress concentrate portion during start-steady state-stop operation. Clarification of the damage evolution process under creep-fatigue loading is important to develop life assessment methods. In this study, strain control creep-fatigue tests wit…
Photodynamic Therapy (PDT) is a minimally invasive radiation therapy currently used in treatment of various cancerous and pre-malignant diseases. Photodynamic therapy with 5-aminolaevulinic acid (5-ALA/PDT) induces DNA damage following photoactivation of Protoporphyrin IX (PpIX), the photosensitizer generated from the…
El objetivo de la investigacion fue determinar por ondas de esfuerzo el modulo dinamico en madera laminada de Pinus pseudostrobus . A partir de tabletas de madera aserrada, se fabricaron 35 probetas de madera laminada de P. pseudostrobus con dimensiones de 0,049 m x 0,053 m x 0,79 m. Para la madera aserrada y la lamin…
In ceramic molding, a paste composed of the ceramic particles and binder is infiltrated into the mold. Fabricating a microstructure by the conventional molding is difficult because of aggregation of the particles. The aggregated particles prevent the paste from being infiltrated into the narrow channels in the mold. T…
Patah tulang terjadi karena kecelakaan lalu lintas, kecelakaan olahraga, serta adanya penyakit tulang. Teknologi yang semakin maju menciptakan sebuah inovasi barn berupa bone filler, yaitu hidroksiapatit yang lebih kompatibel. Pada penelitian ini bertujuan untuk mengetahui nilai kuat tekan, kekerasan dan densitas mate…
The presented study is focused on the development of hard nanostructured W-B-C thin films in the X-B-C structure. Tungsten was chosen as the studied metallic element as it was calculated that W2BC should exhibit the best mechanical properties of the group with B/G of 1.91 and Cauchy pressure of 71 GPa indicating ducti…
To comply with the IMO NOx Tier III regulations, we have developed a new and unique technology called “Low Pressure Exhaust Gas Recirculation (LP-EGR) system”. The LP-EGR system is a system which recirculates a part of low pressure exhaust gas emitted from an engine turbocharger outlet into a turbocharger intake after…
