A method for identification and localization of isolated as well as simultaneous dynamic series insulation failures in transformer winding has been proposed. Trained wavelet network has been employed to identify the fault characteristics, viz. location(s), nature(s) and type of unknown impulse insulation failures. The…
This work demonstrated preparation, characterization, and application of a cobalt phthalocyanine based enzymeless/mediatorless hydrogen peroxide sensor. The cobalt phthalocyanine (CoPc) was retained in polyaniline (PANI) film on a glassy carbon electrode during electrochemical polymerization of aniline and consequentl…
Based on the first principle calculations, we predicted the electronic structures and ferroelectric instability of the asymmetric ferroelectric tunneling junction with the ferroelectric barrier thickness changing, and found two undiscovered and important behaviors, i.e., absence of the critical thickness for the posit…
Transparent conductive In(2-x)Sn(x)O3 (ITO) and In(2-x)Ti(x)O3 (ITiO) films were prepared via RF magnetron sputtering on soda-lime glass substrates at 300 degrees C and investigated with respect to their photoelectric conversion performance compared with the commercial F:SnO2 (FTO) glass. The near infrared ray transmi…
Simple adhesion tests like the pull-out test or the button shear tests have been used in industry for decades. They offer a great potential for comparison of different molding compounds, encapsulants, or adhesives on different types of sub-strates with or without surface treatment. However, for theoretical prediction…
Permanent magnet synchronous machines with fractional slot stator windings using the tooth coil technology require detailed investigations on the electromagnetic parameters due to a very low number of slots per pole and phase. Finite element analyses can provide many results but a subsequent application of the frozen…
Article Influence of Combined Actions on Durability and Service Life of Reinforced Concrete Structures Exposed to Aggressive Environment was published on April 1, 2012 in the journal Restoration of Buildings and Monuments (volume 18, issue 2).
The response surface method (RMS) was used to optimize the color strength (K/S) of the wool fibers dyed with Isatis tinctoria. The eight independent variable terms, in which two of them are categorical and the other six numerical, were selected at two levels (low and high). The ANOVA test results of the linear model s…
In this study, a novel and quick method for selective adsorption of dibenzothiophene (DBT) from gasoline using magnetic molecularly imprinted polymers (MMIPs) as the adsorbent has been employed. The MMIPs were prepared by a surface molecular imprinting technique, using Fe 3 O 4 magnetite nanoparticles as a magneticall…
Abstract Carbon fibres (CF) reinforced aluminium (Al) matrix composite material was fabricated using a special flux of potassium iodide (KI) with 10 weight% of potassium hexafluoro‐titanate (K 2 TiF 6 ) at 820°C under protective argon atmosphere. The fabrication was performed with no extra pressure or mixing applied.…
Content-Centric Networking (CCN) is a recently proposed networking architecture that can potentially lead to reduced bandwidth usage and better scalability and security as compared to the current IP-based architecture. In this paper, we conduct an energy consumption analysis of content-centric networking and IP-based…
Gelatin used for capsule shells can be derived from porcine origin. Some religion like Islam prohibited their followers to consume any products containing porcine derivatives including porcine gelatin in the products. Consequently, some rapid and reliable techniques are continuously developed for detection of porcine…
Photodynamic therapy (PDT) is a clinically approved method for treatment of cancer, microbial infections, and some other diseases. PDT has proved effective in the treatment of malignancies of various organs, including lung, bladder, gastrointestinal tract, and skin, and in the therapy of bacterial infection of skin wo…
We report that the endurance degradation behaviors of transitional metal oxide (TMO) based resistive random access memory (RRAM) is dominated by three different steps and correlated with extra oxygen vacancy accumulation during SET/RESET switching process. The physical origin of endurance degradation due to the pulse…
Hydroxylated fullerenes (C₆₀OH(x)) or fullerols are water-soluble carbon nanoparticles that have been explored for potential therapeutic applications. This study assesses acute in vivo tolerance in 8-wk-old female Sprague-Dawley rats to intravenous (iv) administration of 10 mg/kg of well-characterized C₆₀(OH)₃₀. Compl…
The phase compositions, microstructure and especially phase interfaces in the as-cast and heat-treated Nb–Ti–Si based ultrahigh temperature alloys have been investigated. It is shown that β(Nb,X)5Si3 and γ(Nb,X)5Si3 are the primary phases in the Nb–22Ti–16Si–5Cr–5Al (S1) (at%) and Nb–20Ti–16Si–6Cr–4Al–5Hf–2B–0.06Y (S2…
We studied the interrelation between the composition, morphology, and helium permeability of the shell of narrow fractions of nonmagnetic nonperforated cenospheres extracted from cenosphere concentrates of fly ash of the sialic type with the use of technological stages of hydrodynamic, magnetic separation, sizing, and…
Polymer electrolyte-based unitized reversible fuel cells (URFCs) combine the functionality of a fuel cell and an electrolyzer in a single device. In this study, the influence of hydrophobic agent in the gas diffusion layer (GDL) of URFC was investigated. The titanium (Ti)-felt GDL which treated with different percent…
An aqueous suspension containing magnetic nanoparticles is not stable because the nanoparticles aggregate. As the aggregates size increases and the number of particles in suspension decreases, the rheological properties of the nanofluid, which are important for biomedical applications, change tremendously. Modified ve…
Overexpression of recombinant proteins in bacterial systems (such as E. coli) often leads to formation of inactive and insoluble ' inclusion bodies' . Protein refolding refers to folding back the proteins after solubilizing/unfolding the misfolded proteins of the inclusion bodies. Protein aggregation, a concentration…
