In this study, two types of water-soluble sulfur, LSA and LSB, were developed and the influence of the water-soluble sulfur on the mechanical properties and durability of concrete were experimentally evaluated. In order to evaluate mechanical properties and carbonation resistance of concrete with water-soluble sulfur,…
The present study attempted a comparative exploration of EFL teachers’ views in relation to integrating the CLIL (Content and Language Integrated Learning) approach in the context of Greek and Cypriot primary education. It is considered that the provision of curriculum content in a second/foreign language (L2/FL) can…
Hydraulic automatic gauge control (AGC) is a very important part of rolling mill for magnesium plate rolling. The control effect of automatic gauge control system influences the quality of the rolled product directly. AGC system is an essentially nonlinear, time delay, time-varying, large inertia, multivariable and co…
A new ultrasonic spray pyrolysis method, called carbon nanoparticle-addition ultrasonic spray pyrolysis (CNA-USP), is developed to synthesize nanoparticles of electrolyte material for solid oxide fuel cell applications. In CNA-USP, carbon nanoparticles are added in a precursor solution. First, Gd0.1Ce0.9O1.95 (GDC) pa…
In this study, effect of heat treatment on the microstructure and damping capacity of hot rolled magnesium alloys was investigated. The microstructure of hot rolled magnesium consisted of dendrite structure and $Mg_{17}Al_{12}$ compounds precipitated along the grain boundry. The dendrite structure was dissipated and $…
Modeling of the evolution of distributed damage and plasticity such as micro-cracking, void formation, dislocation densities, and shear bands necessitates strain-softening constitutive models. The nonlocal continuum concept has emerged as an effective means for regularizing the (initial) boundary value problems with s…
The metallurgical and mechanical characteristics, toughness and corrosion resistance of dissimilar welds between super duplex stainless steel UNS S32750 and carbon steel ASTM A516Gr.70 have been evaluated. Three heat inputs of 21.12, 24.00, 26.88kJ/cm were employed to make joints of dissimilar metals with flux cored a…
Swelling of the heat-treated netting for gillnet was estimated through the netting height in square acrylic tank. Experimental Nylon netting and PBSAT netting were heat-treated by using the high-degree vacuum method in hot water after net making. Heat-treatment temperatures were conducted with Nylon netting $105^{\cir…
The present work reports electrochemical synthesis of MgB6 from molten salts using the precursor consists of LiF-B2O3-MgCl2. An attempt has been made to synthesize metastable phase MgB6 crystal by electrolysis method. DTA/TGA studies were made to determine the eutectic point of the melt and it was found to be around 9…
Nowadays thin-film solar cells are increasingly used mainly because of their low cost. In recent decades the performance of these cells were significantly improved. In this work, we simulated a solar cell type GaAs using software (PC1D) to analyze certain parameters, in particular the properties of the window layer, b…
We report the syntheses, structures, and magnetic properties of cis-[Fe(pizR)2(NCS)2] complexes based on the pyridyl imidazoline ligands 2-(2′-pyridinyl)-4,5-dihydroimidazole (pizH, 1) and 2-(2′-pyridinyl)-4,5-dihydro-1-methylimidazole (pizMe, 2). The ligands, complexes, and magnetic measurements are chosen to separat…
Carbon nanofibers were in-situ synthesized on porous carbon composites via a simple and economic technique of oxyacetylene torch ablation without catalyst assistance. The resultant nanofibers with good crystallinity in the (002) plane were polycrystalline graphite, which grew in the ablation center region. They were g…
We investigate the dynamic and static properties of a polymer melt near solid surfaces. The melt, composed of linear chains, is confined between two solid walls with one of the walls being repulsive; whereas the opposite, attractive wall, is characterized by different degrees of roughness, caused by an array of short…
수소화기상증착에피탁시로 성장된 GaN 단결정의 표면 특성을 정밀하게 측정하기 위해, 용융 KOH/NaOH 습식화학에칭법을 적용하였다. KOH/NaOH 습식화학에칭법에 에칭속도는 기존의 황산, 인산과 같은 etchant에 비해 느린데, 이는 불용성 코팅층의 형성에 의한 것이다. 따라서 이 방법으로 etch pits density를 더 효율적으로 평가할 수 있었다. 성장된 GaN 단결정을 XRD(X-Ray Diffraction), XRC(X-ray rocking curve)로 결정성을 분석하였으며, 에칭 특성과 표면 형상은 주자전자현미경을 이용하여 관찰하였다. 에칭 실…
This paper presents the analysis and results obtained with the regenerative braking technique applied to the linear induction motor used for the traction of MagLev-Cobra, an urban transportation vehicle. The motor, with a special geometry, the converter, with bidirectional power flow, and the drive control are reporte…
Value added paneer was prepared to improve the fibre content in the otherwise fibre deficient paneer. Cereals like wheat and finger millet at 1% level was included in the preparation of paneer. Inclusion level of more than 1% caused pasty consistency. Sensory analysis was also carried out on the designed paneer. It wa…
The preparation of in situ NbC particles reinforced steel by adding prefabricated blocks comprising Nb(C) solid solution and Fe powders into a low carbon steel melt was studied. Experimental results demonstrate that nano-sized NbC particles can be distributed uniformly in the steel matrix. Furthermore, the as-casted m…
A considerable amount of mill scale is generated fr om steel making plants annually. Although some industries us e it as raw material, since it contains iron in the form of FeO , Fe 2O3, and Fe 3O4, it can be considered as a valuable metallurgical raw material in iron and steel making industry as well. Thus, the aim o…
Oxidative damage results in protein modification and is observed in numerous diseases. Human serum albumin (HSA), the most abundant protein in the plasma, exerts important antioxidant activities to prevent oxidative damage. This paper focuses on the characterization of chemical changes in HSA that are induced by oxida…
Abstract: In this study, a melt-blown nonwoven filter for medical masks was manufactured using an online hydrocharging system. The effects of basis weight (gsm) and die to collector distance (DCD) on the breathing resistanceand filtration efficiency were investigated. Hydro charging of the nonwoven web seemed to impro…
