Plasticized poly(vinyl chloride) (PPVC) is widely used in the automotive industry in the design of structural parts for crashworthiness applications. Thus, it is necessary to study and understand the influence of the mechanical response and mechanical properties of PPVC over a wide range of strain rate, from quasi-sta…
地震観測に基づく都市ガス供給遮断システムを「k-out-of-n遮断システム」と定義し，東北地方太平洋沖地震における第1次緊急停止判断を事例として，観測SI値とブロック供給遮断確率の関係を表す機能的フラジリティ関数を，対数ロジスティック分布を用いて構築するとともに，k-out-of-4遮断システム(k=1, 2, 3, 4) とした場合の結果の相互比較を通じて，そのシステム特性を明らかにした．またリサンプリングを復元抽出・非復元抽出としたbootstrap法により，仮想的な k-out-of-n遮断システムを多数生成して供給停止シミュレーションを行った．供給停止割合の平均値と標準偏差の比較を通じて，多様なシステム形態および地震観測…
We present the results of the calculations of longitudinal and Hall conductivities of AB-stacked bilayer graphene as a function of frequency, finite chemical potential, temperature both with and without magnetic fields on a base of 2- and 4-band effective models. The limited cases of the conductivities for direct curr…
Protein folding [1] is the process of formation of a functional 3D structure from a random coil — the shape in which amino-acid chains leave the ribosome. Anfinsen’s dogma states that the native 3D shape of a protein is completely determined by protein’s amino acid sequence. Despite the progress in understanding the p…
A 64 Mbit phase change memory chip is fabricated in 40 nm CMOS technology. An improved fully-differential sense amplifier with a bias voltage instead of the reference resistor branch is proposed to diminish the chip area. The transient response capability of the proposed sense amplifier is improved by removing the lar…
Zusammenfassung Als transkranielle Magnetstimulation (TMS) wird ein Verfahren bezeichnet, bei dem ein Stimulator über eine Spule kurze elektromagnetische Pulse mit einer Flussdichte von bis zu 2 Tesla induziert, welche die Schädelkalotte mit wenig Abschwächung durchdringen und zu einer Depolarisierung neuronaler Zellv…
The vacancy-type defects in the aluminum single crystal foils after a series of the cyclic tensions were studied using positron annihilation. Two components were identified in the positron lifetime spectra associated with the annihilation of free positrons and positrons trapped by dislocations. With increasing number…
In this work the impact of the fabrication nonidealities on the reflection features of dielectric high-contrast gratings (HCGs) is discussed. The grating performance is quantified considering the plane-wave scattering problem. This is solved by means of a novel full-wave simulator based on the mortar element method. T…
Indentation is widely used to investigate the elastic and plastic properties of mechanical materials, which includes the strain rate sensitivity. The indentation exhibits an inhomogeneous strain distribution in contrast to compression and tensile tests with homogeneous deformation. Thus, the strain rate of the indenta…
The work presents the development of new algorithms for calculating the fraction of thermal energy dissipated during the irradiation on the inner surface of pores. On the basis of these algorithms, the simulation of heat transfer in three-layered systems was carried out taking into account the dissipation of thermal e…
This study aims at understanding the bake hardening ability of ultra low carbon BH220 steel at different strain rates. The as-received material has been pre-strained to four different levels and then deformed in tension under (a) as pre-strained state and (b) after baking at 170 ∘C for 20 minutes, at three different s…
The aim of the present work is to study the effect of Nano-barium sulfate additions on the physic-mechanical properties of hardened cement pastes. Nano-barium sulfate was prepared by the precipitation method. Eight mixes of filled cement pastes containing 0.5 wt%, 1.0 wt%, 1.5 wt% and 2.0 wt% of both nano-barium sulfa…
The mechanism in the formation of periodontal polyp has been established in several histological studies but details on cell differentiation and/or proliferation have not been elucidated. In the present study, we established a convenient and possible experimental system using ddY mice. Briefly, pentobarbital sodium (S…
Composites of whey dangke and agar can form edible flm. The downside of this edible flm are fragile, brittle and infexible. Addition of glycerol, which is one of plasticizers, may improve characteristics of edible flm to be more elastic, fexible and not easy to become fragile. The proper use of glycerol will affect th…
Ballistic impact on composites has been a challenging problem as seen in the abundant literature about the subject. Continuum models usually cannot properly predict deflection history on the back of the target while at the same time giving reasonable ballistic limits. According to the authors the main reason is that,…
Michael North opened the discussion of the paper by André Bardow: It is an interesting paper, but you do not discuss the lifetimes of the polymers? One application of polycarbonates is in mattresses and we all sweat at night. Carbonate bonds are more prone to hydrolysis than ether bonds, so wou
A novel adsorption type gel plugging agent (ATGPA) was prepared using acrylamide (AM), acrylic acid (AA), diallyl dimethyl ammonium chloride (DMDAAC), 2‐acrylamido‐2‐methylpropanesulfonate (AMPS), formaldehyde (HCHO), resorcinol (C 6 H 6 O 2 ), and thiocarbamide (CH 4 N 2 S) as raw materials under mild conditions. ATG…
Oxidation of octane in the presence of benzaldehyde over a AuPd catalysts leads to the formation of octyl benzoate.
Novel heteroleptic ruthenium(II) complex [Ru(CF 3 -ppyd-TPA)(tctpy)] + (ppyd = 2-phenyl-6-(pyridin-2-yl)pyridine, TPA = triphenylamine, and tctpy = 4,4′,4″-tricarboxy-2,2′:6′,2″-terpyridine) was designed and investigated to increase its molar absorptivity compared to [Ru(ppd)(tctpy)] + (ppd = 2-(3-(pyridin-2-yl)phenyl…
The Zn x Cd 1–x S/TiO 2 hierarchical heterostructures were successfully fabricated by combining electrospinning technology and hydrothermal methods. The morphology, crystallinity, composition and band gap of Zn x Cd 1–x S/TiO 2 were characterized by SEM, XRD, EDS, and UV-vis diffuse reflectance spectroscopy. The resul…
