In this paper, we are interested in the study of the asymptotic behavior, in terms of finite-dimensional attractors, of a generalization of the conserved phase-field system proposed by G. Caginalp. This model is based on a heat conduction law recently proposed in the context of thermoelasticity and known as type III l…
High-temperature superconducting (HTS) cable terminal is an important part of the HTS cable system, which functions to improve the internal electric field distribution and the electrical insulation strength of the cable termination. In this paper, the particle swarm optimization method is adopted to the 35-kV HTS cabl…
The authors report high-efficiency GaN-based light-emitting diodes (LEDs) fabricated with identical Ag contact formed on both n- and p-layers. Ag contacts thermally annealed at optimized conditions yielded low specific contact resistances of 4.5 × 10(-4) and 9.4 × 10(-4) Ωcm(2), and high optical reflectivity (at 450 n…
The molecular beam epitaxy growth of Fe on MnAs/GaAs(001) leads to the formation of a new phase of the FeMnAs compound at the Fe/MnAs interface. We investigated the structural and magnetic properties of this interfacial layer by high angle annular dark field imaging in a scanning transmission electron microscope (HAAD…
We employ the term offset-continuation trajectory stack, or briefly OCT stack, to describe the act of computing efficiently the data stack along approximate common-reflection-point (CRP) trajectories. The method allows to construct a stacked common-offset gather, that may have (or not) been collected in the field. In…
Prediction and control of membrane morphology using multi‐phase thermodynamic knowledge are of growing interest. The water/dimethylsulfoxide/polyethersulfone ternary system is a widely used casting dope for the preparation of MF, UF, and NF membranes. In the current study, Flory–Huggins (F–H) model was applied to pred…
Salinitas merupakan salah satu faktor pembatas yang mempengaruhi jenis fitoplankton. Fitoplankton yang mampu hidup di salinitas tinggi memiliki manfaat bagi kehidupan manusia. Tujuan dari penelitian ini antara lain adalah mengetahui jenis fitoplankton pada berbagai salinitas dalam tahapan pembuatan garam, membuktikan…
This paper presents the self-potential (SP) method results and the comparison of this results with electrical resistivity data in delineation of potentially impacted areas by leachate flow from Jockey Club Landfill, located at Estrutural City, Brasília-DF. The survey was made at the south part of landfill boundary, ne…
Swamp Lake, Yosemite National Park, is the only known lake in California containing long sequences of varved sediments and thus has the potential to provide a high-resolution record of climate variability. This preliminary analysis of the diatom assemblages from a 947-cm-long composite sediment core (freeze core FZ02–…
There are substantial ecological and evolutionary costs to sexual reproduction and there is only a narrow range of conditions that favors the evolution of high rates of sexual reproduction in species that are capable of both sexual and asexual reproduction. Considering the evolutionary costs and benefits of sexual rep…
Tetraaniline nanostructures/magnetite nanoparticles (Fe 3 O 4 NPs) have been prepared via in situ self-assembly method using ammonium persulphate as an oxidant in the presence of p -toluene sulphonic acid as a dopant as well a soft template. The effect of the concentration and molar ratio of p -toluene sulphonic acid…
Epitaxialfilms of Fe38.5Pd61.5 at the L10-L12 eutectoid composition have been grown on MgO(001) oriented substrates by pulsed laser deposition. The effect of deposition temperature on the magnetic,microstructural, and crystallographic natures of these films are discussed. The films in this study exhibit atomic orderin…
The behavior of end-adsorbed bimodal PS–PEO block copolymer systems was studied with neutron reflectivity experiments, both under static conditions (zero shear rate) and under a stepwise-increasing shear flow, up to a critical shear rate where desorption occurs. It is found that when the height of one kind of chain in…
The electron paramagnetic resonance (EPR) properties of limestone from a certain Egyptian site were investigated in order to propose an efficient and low-cost gamma dosimeter. Radiation-induced free radicals were of one type which was produced in the limestone samples at g=2.0066 after exposure to gamma radiation (60C…
The functionalized carbon nanotube has been shown to be a viable filler material to increase the thermal conductivity of elastomer heat sinks. However, the effect of the amount of fillers used, that is, the carbon loading in elastomers is still unknown. This study focuses on varying the carbon loading percentage, in 0…
ABSTRACT In this article, we present a strategy for fabricating polypropylene (PP)/polypropylene‐regrafted single‐walled carbon nanotube (PP‐re‐g‐SWNT) composites with a high loading of single‐walled carbon nanotubes (SWNTs; 20 wt %). The PP‐re‐g‐SWNTs were characterized by X‐ray photoelectron, Fourier transform infra…
To assess internal annual dose in the general public in Aomori Prefecture, Japan, 80 duplicate cooked diet samples, equivalent to the food consumed over a 400-d period by one person, were collected from 100 volunteers in Aomori City and the village of Rokkasho during 2006–2010 and were analyzed for 11 radionuclides. T…
Iminodiacetic acid (IDA) and tris(2-aminoethyl)amine (TREN) chelating ligands were immobilized on poly(ethylene vinyl alcohol) (PEVA) hollow-fiber membranes after activation with epichlorohydrin or butanediol diglycidyl ether (bisoxirane). The affinity membranes complexed with Cu(II) were evaluated for adsorption of h…

As an original synthetic route to molecular magnetic materials, we have reacted partially-blocked cyanometalates with preformed coordination cluster. The association of the fac -[Fe(Tp)(CN) 3 ] − assembling metalloligand with the [Cu 3 (OH)(pz) 3 ] 2+ trigonal cluster has afforded a novel coordination network where th…
