Nanocarbons were synthesized from benzene - water - sodium dodecyl sulfate（SDS）and benzene-（water-ethanol）-SDS systems using solution plasma. The stabilized emulsion formed in the benzene-water-SDS and benzene-（water-ethanol）-SDS. The specific surface areas of nanocarbons synthesized from benzene-water-SDS increased w…
Stress corrosion cracking (SCC) has recently been observed in Ni-based alloy welds in nuclear power plants, despite countermeasures to prevent it. In the repair welding, temper bead welding (TBW) is applicable when post weld heat treatment (PWHT) is difficult to carry out. In TBW, the welding process variables are app…
This work is dedicated to researches of durability of engineering constructions ferroconcrete exposed to synergistic influence of corrosion damages and having concrete and working reinforcement damages.
The large deformation including bucking may occur due to welding on thin-plate structures. The prediction of welding distortion on thin-plate structures is difficult since change of deformation mode may occur. In this research, in order to evaluate the welding distortion of thin-plate structures, an analysis method th…
AN ABSTRACT OF THE THESIS OF James Morrow, for the Master of Science degree in Mechanical Engineering, presented on November 3, 2017, at Southern Illinois University Carbondale. TITLE: INVESTIGATION OF THE MATERIAL PROPERTIES OF CERIUM OXIDE WITH DOPANTS FOR AN OXYGEN TRANSPORT MEMBRANE MAJOR PROFESSOR: Dr. Kanchan Mo…
A closed form solution expressing humidity dependence of static fatigue crack velocity of SiO2-based materials is derived by combing a reaction controlled crack velocity equation and a humidity dependent surface energy equation based on atomistic simulation. Calculated results by using this solution coincide well with…
The applications of wrought magnesium (Mg) alloys to structural components in transportation vehicles are limited because of insufficient mechanical properties and high processing cost originating from poor hot-workability and poor formability at ambient temperature. In order to reduce the processing cost, improvement…
Industrial rubber, commonly used in the fabrication of tires and engine mounts, exhibits nonlinear viscoelastic behavior. In the design of these rubber products, it is important to capture the stress–strain responses under arbitrary loading conditions. However, the stress–strain responses exhibit complicated behavior,…
Paper sludge(abbreviated as PS in this report) which is a residue after paper making is usually incinerated, heat being recovered. The problem is resultant paper sludge ash(abbreviated as PS ash) , and the paper industry as a whole discards several million tons of it, B.D. basis, every year 1) , though its volume is l…
In this thesis I discuss the effects of electron-electron interactions on the properties of recently created two dimensional conducting layers which form near the surface or interface of transition-metal oxides, most commonly SrTiO$_3$. Although these systems typically contain far fewer than one conduction band electr…
Numerical method for analyzing pattern formation on a curved surface is investigated in this study. A multiphase-field model is applied, and the equations are solved by the finite difference method. The lattice points for the numerical integration are disposed on a spherical surface. In our previous study, several reg…
Foamed metal is three-dimensional network metal of porous such as a sponge. The formed metals have many unique properties, such as lightweight property, sound absorbability, and shock absorption. And so the materials come into action to industrial products. However, the strengths of the formed metal are lower than of…
Thermal networks of Volzhsky, Volgograd region, are the object of research. The aim of this paper is to determine quantitative reliability indicators expressed as failure rates, time periods between failures and establishing a failure distribution law. Research of statistical data on failures of thermal networks have…
Liquid hydrogen is an attractive solution for long-range distribution. The largest barriers for implementing large-scale hydrogen liquefaction plants are currently their high energy consumption and cost. The heat exchangers are among the most important equipment in these plants. It has been shown that it may be benefi…
A liquid-filled glass bottle can fracture when an impact is imposed. High-speed photography reveals that its fracture is caused by the collapse/rebound of cavitation bubbles. In order to avoid the fracture, accurate prediction on cavitation onset is crucial. However, conventional cavitation number C, which is based on…
Japan imports most of its primary energy needs from other countries to meet up with its ever-increasing energy demand, also this primary energy supply is mostly from politically unstable areas of the world. This however makes the supply structure vulnerable for the reason stated above, the decline in fossil fuel reser…
嫌気性アンモニア酸化（アナモックス）を用いた連続処理リアクターによる窒素除去に及ぼす温度の影響を予測するための数理モデルを構築した。細菌の増殖速度の最高値を与える基本温度式を熊本の下水処理施設と北海道の畜産廃水処理施設の活性汚泥をそれぞれ種汚泥とする低温型リアクターLow－R1とLow－R2のアナモックスモデルに組み込んだ。最低温度（Tmin）4℃、最高温度（Tmax）36℃の範囲において、Low－R1のアナッモクス細菌の比増殖速度の最大値（μopt）を最適温度（Tmax）26℃において0.052d－1に設定した（実験値との相関係数r = 0.851）。Low－R2のμopt、Topt、Tmin、Tmaxの値は、それぞれ0.089…
