A partir de algunas propiedades termodinámicas clásicas, en este trabajo se calcularon en mezclas binarias 1,4-dioxano + agua, y mediante el método de las integrales inversas de Kirkwood-Buff, los parámetros de solvatación preferencial, esto es, las dif
Evolutions of defects and helium contained defects produced by atomic displacement and helium deposition with helium implantation at different temperatures in novel high silicon (NHS) steel are investigated by a slow positron beam. Differences of the defect information among samples implanted by helium to a fluence of…
To enhance torque density by harmonic current injection, optimal slot/pole combinations for five-phase permanent magnet synchronous motors (PMSM) with fractional-slot concentrated windings (FSCW) are chosen. The synchronous and the third harmonic winding factors are calculated for a series of slot/pole combinations. T…
The properties and features of crystals are closely related to their defects. The latest studies show that there could exist “defect”, we term it as flow units, in amorphous matter with disordered structure and unique mechanical and physical properties. However, the features and its relationship with the properties of…
A comparative study of the noncovalent interaction of the cyanine dye probe 3,3′-di-(γ-sulfopropyl)-4,5,4′,5′-dibenzo-9-ethylthiacarbocyanine betaine with serum albumins of different vertebrates: rat, rabbit, bovine, and human serum albumins (RSA, TSA, BSA, and HSA, respectively) has been performed by spectral and flu…
Nanoparticles (NPs) are increasingly used throughout the world for many purposes. The resulting exposure increases the relevance of efforts to assess their effects. The activities of NPs are related to many structural features, including their shape, composition and size. Applying Quantitative Structure-Activity Relat…
In order to improve the accuracy of the strength assessment of operating reinforced concrete structures, it is rational to use the model with a discrete location of reinforcing bars with the actual characteristics of adhesion to concrete reinforcement. The problem of pulling the reinforcing bar from the concrete block…
Abstract In this study, macromolecular arrangements in fibers were investigated and a novel approach based on model development for partially oriented (POY) polyethylene terephthalate (PET) yarn morphology was proposed. Differential scanning calorimeter (DSC) analysis, Fourier transform infrared (FT-IR) analysis, boil…
The switched reluctance motor (SRM) drives have been widely used in aircraft applications due to the motor advantages like high speed operation, simple construction, no windings on rotor. But high torque ripples and acoustic noise are main disadvantages. The current hysteresis chopping control is one of the important…
Periodontal regeneration is a complex healing pattern of soft and hard periodontal tissues. Recent approaches in reconstructive biology utilize mechanical, cellular or biologic mediators to facilitate reconstruction/regeneration of a particular tissue. In this study, the concept of tissue engineering was applied by us…
To meet the future development in vehicle drivetrains, the Institute of Vehicle Concepts of the German Aerospace Center (DLR) aims to prove, that exhaust heat recovery using a Thermoelectric Generator (TEG) is, even with more electrification, still a promising concept to increase efficiency. Together with material res…
Soil organic carbon (SOC) and soil Olsen-P are key soil fertility indexes but information on their relationships is limited particularly under long-term fertilization. We investigated the relationships between SOC and the percentage of soil Olsen-P to total P (PSOPTP) under six different 15-yr (1990–2004) long-term fe…
Summary We report homogeneous nucleation and first order crystallization kinetics for the PEO block within a PEO‐b‐PB diblock copolymer infiltrated within alumina nanopores. For the highly confined heterogeneity free PEO block nano‐domains, the overall crystallization kinetics is dominated by nucleation and therefore…
Diatom and water chemistry samples were collected during the austral summer of 2007 from lakes, streams and bogponds on Ile Amsterdam (TAAF), a small island located in the southern Indian Ocean. A diverse diatom flora of 104 taxa was found, dominated by several Pinnularia taxa, Frustulia lebouvieri, Kobayasiella suban…
Mg–3.0Nd–0.4Zn–0.4Zr magnesium alloy were prepared by cast-extruding and chip-extruding. Microstructure, tensile and creep properties of the alloy were investigated. The results show that the alloy exhibit particle dynamic recrystallization during extrusion. The cast extruded-T6 rods at room temperature have a highest…
Graphene which is a single atom layer of carbon film with the interesting properties of high carrier mobility, high carrier concentration, high thermal conductivity, high velocity saturation, and reduced short channel effects, is emerging as a replacement of the ubiquitous silicon. This is particularly true for high-s…
DC distribution systems have become more appealing in recent years due to its higher energy efficiency. They have already been applied in data centers, commercial buildings, electrical vehicles charger stations and DC micro grid systems, etc. However, electrical arcing is a common phenomenon in DC applications. Arcing…
In 1979, a Hebrew University biochemist named Yechezkel Barenholz teamed with Alberto Gabizon, a newly minted Ph.D. from the Weizmann Institute of Science, to find a better way to give chemotherapeutic doxorubicin to patients with cancer.
The use of permanent magnets for bias magnetization is a known technique to increase the energy storage capability in DC inductors, resulting in a size reduction or increased current rating. This paper presents a brief introduction on the different permanent magnet inductor's configurations found in scientific literat…
