In this study, effect of thermal fatigue on tensile property of plain woven jute fiber reinforced PLA was investigated. As a condition of thermal fatigue test, a range of temperature was from 35°C to 55°C. The maximum number of cycle was 200 cycles. The quasi-static tensile test was conducted after thermal fatigue tes…
On the blade of wind power generation of the land, the sand erosion damage has occurred. In the case of the blade of the offshore wind power generation, the rain erosion damage supposed to be occurred. In many cases, blades of wind power generation are made of GFRP (Glass Fiber Reinforced Plastics). In this study, we…
The authors have carried out integrated assessment of high-chromium cast iron (16…18% of Cr) with the development of analytical apparatus based on a complex computer analysis of metallographic images. The results obtained confirm the effectiveness of phase investigation method by overlapping the data with those obtain…
The shape memory effect (SME) in Fe-Mn-Si based alloy is associated with γ&elarr;ε martensitic transformation which is caused by motion of the Shockley partial dislocation. The variants in Fe-Mn-Si based alloy could appear the four orientations according to Shouji-Nishiyama (S-N) relation in the austenite phase (A-pha…
Titanium and its alloys have low density, high specific strength, high fatigue strength, and good corrosion resistance. However, today they are underutilized in industry due to their high cost and poor wear resistance. To further improve their properties, TiB- and TiC-reinforced Ti matrix composites (TiB/Ti and TiC/Ti…
It is important to investigate the molten jet behavior in fuel coolant interaction (FCI) during reactor severe accidents, which affects the subsequent phenomena, such as vapor explosion in light water reactor (PWR) or the molten core coolability in fast breeder reactor (FBR). The focus of the present study is placed o…
We measured pressure drops and investigated flow properties of water and dilute aqueous polymer solutions of polyacrylamide (PAA) in capillary flows with bend section. Capillary sizes used as 125 μm and 410 μm. For PAA, dilute concentrations were used (in the range from 1 ppm to 100 ppm). For comparison, straight capi…
This paper reports an application of nondestructive testing method to estimate the microstructure of the thin wall ductile cast iron with casting surface. To make thin wall ductile cast iron without chill structure, processing techniques have been developed recently. The microstructure and mechanical properties of duc…
During the 70' and 80' of the last century 12 units of Russian VVER-440 type of reactors were started to build on the territory of Czech and Slovak Republic. Nowadays 2 units were already shutdown, 8 are operates and 2 are still under construction. During theirs operation period wide range of modifications and upgrade…
Open-cell porous aluminum (Al) was fabricated by friction powder sintering process. In this process, a mixture of Al powder, ADC12 Al alloy powder and sodium chloride (NaCl) powder as spacer particle was used as starting materials. The powder mixture was sintered only by rotating tool plunged into the mixture. NaCl wa…
Noble metal nanostructures have seen a steady increase in biomedical application over the last several decades; new diagnostic and therapeutic modalities are under intense investigation. Many of these applications are possible because of post-synthetic modifications to the particle surface. These modifications take a…
筆者らは、薬剤の副作用の軽減を目標に、X線活性化型のプロドラッグの開発を進めてきた。このプロドラッグとは、化合物そのものは毒性を示さないが、X線照射によって構造が活性な薬剤へと変わり、効果を発現するスマートな薬剤である。薬剤をプロドラッグ化することによってX線照射した病変部でのみ抗がん活性を発現できることから、薬剤が抱える副作用の問題を解決できると考えた。筆者らはアジドメチル基、インドールキノン基、ジスルフィド結合等のX線還元反応を受けて結合開裂を生じる官能基を見出し、各種プロドラッグを設計してきた。本稿では、筆者らが進めてきた低分子抗がん剤、核酸医薬品、および薬剤運搬システムのX線照射による活性制御について、分子設計の視点から解…
The JAERI's Reprocessing Test Facility (JRTF) was the first engineering-scale reprocessing facility constructed in Japan. The JRTF was operated from 1968 to 1969 to reprocess spent fuels from the Japan Research Reactor No.3 (JRR-3). As a result of the operation (total 3 runs) by PUREX process, 200 g of highly purified…
Lanthanum-based perovskites has emerged to be a promising candidate as cathode for solid oxide fuel cells (SOFCs) and as oxygen separation membrane. With regard to mechanical properties, anomalous behavior, known as ferroelasticity, has been reported in recent years. Systematical and experimental investigation relates…
The effects of specimen size as well as notch size on the onset of longitudinal splitting in a unidirectional carbon/epoxy laminate have systematically been examined. For this purpose, static tension tests were performed on one-, two- and three-dimensional geometrically similar specimens containing a central circular…
Protein adsorption on solid surfaces has been gaining wide interests in the fields of drag delivery, biosensor, and biomedical diagnosis. Peptides, small proteins, also bind to solid surfaces. Recently, there are a variety of peptides have been developed and reported which show not only a binding affinity on solid sur…
Alkanethiol molecules chemically adsorbed on the gold (Au) surface are considered to investigate the characteristics of the Self-assembled monolayer (SAM) interface at room temperature. The analysis is based on the molecular dynamics (MD) method. We use two alkanethiols with different chain lengths, that is, ethanethi…
A waveform based methodology for prediction of variable loading fatigue life of composites is developed. The variable R-ratio fatigue tests in which the stress ratio of fatigue loading alternates between two specified values with different stress levels that correspond to the same number of cycles to failure are first…
AC Magnetic suspension system using magnetic resonant coupling has been proposed which has the performance of noncontact energy transfer to the suspended object (floator). This system has the self-stabilization property so that passive suspension is possible. In this paper, an experimental apparatus is fabricated whic…
Recent years, the drug delivery systems (DDS) require multi-functionality and high functionality.
