Provides an assessment of additional estimated losses of electricity in power systems cranes in river ports. The cause of additional calculated power losses is the use of step load graphs instead of the original graphs as the initial information. Clarification of the calculated power losses is achieved by taking into…
The purpose of the research was to obtain hydrophilic and biocompatible polymeric materials. The obtained bionanocomposites were investigated in terms of biocompatibility by using a fibroblast cell line (NCTC clone L929), water contact angle measurements, morphology (by SEM measurements) and structural composition (by…
In this contribution we present an approach towards programmable shape memory transformations utilizing the intrinsic physical properties of a ternary polymer-based composite. The underlying idea is to use an open porous elastic skeleton as the base, where the pores are filled with a component that can alter its elast…
In order to prepare angiopep-2 modified fluorescein isothiocyanate-labeled neurotoxin nanoparticles( ANG-NPs/FITCNT),emulsion/solvent evaporation method was used with m PEG-PLA and ANG-PEG-PLA( in proper proportions) as carriers and with FITC-NT as drug. With particle size and encapsulation efficiency as comprehensive…
The mathematical research on thermal protective clothing mainly uses mathematical models to describe the thermodynamic laws of thermal protective clothing, air layer and skin system, and provides theoretical reference for the functional design of thermal protective clothing. In this paper, the heat transfer process is…
Abstract The effect of the acidic characteristics of an alumina support on the properties of formed palladium particles is studied to improve the activity of catalysts for the hydrogenation of unsaturated hydrocarbons of the pyrogasoline fraction. High catalytic activity is characteristic of highly dispersed palladium…
Abstract—Composite fibers of starting mixtures of aluminum, yttrium, and calcium oxides and fibrous composite materials consisting of these fibers and a molybdenum matrix are fabricated by internal crystallization. The structure, the strength, and the cracking resistance of the fibers are studied in the temperature ra…
Ethanol sensing performance of the NiO sensor has been investigated from room temperature (RT) to optimum temperature (Topt.). A low cost sol-gel spin coating technique has been employed to develop the surfactant embellished NiO sensor for ethanol sensing. The scanning electron microscopy (SEM) results have evidenced…
Abstract—The results of studying the mechanical behavior of a 23Kh15N5AM3-Sh (VNS9-Sh) sheet TRIP steel with various initial martensite contents during static tension are supplemented and generalized. A correlation between the type of stress–strain curve and the acoustic emission (AE) signal activity and power, on the…
Considered the issues of interaction between man and nature. Noted that this interaction is fundamental in the existence of modern civilization. The question of possible impact on nature and society with the aim of preserving the existence of human civilization. It is shown that the study of this issue goes towards th…
Abstract The effect of the fraction and the direction of deformation on the structure and the hardness of commercial-purity titanium severely deformed in a Bridgman cell at room temperature is studied. The direction of rotation of a movable anvil considerably affects the conditions under which the ω phase precipitates…
Over the past few years, food safety has become a hot topic of research due to the rapid rise in foodborne diseases. Consumption of food contaminated with pathogens or toxins has caused numerous fatal health incidents worldwide. Biosensing platforms capable of early detection of food contaminants with high specificity…
This paper presents a nonlinear calculation method for unbalanced magnetic force (UMF) in surface-mounted permanent magnet (SPM) machines based on subdomain and magnetic circuit hybrid model (SMCHM). The hybrid model transforms the nonlinearity effect in stator core to equivalent current on the edges of slots. The cur…
This paper shows the effectiveness of the microelectronic strain gage sensors application, the expediency of the energy-information method using for sensor modeling with the purpose of automating the synthesis of their physical operation principle is proved, an energy-information model of the bridge circuit has been d…
Reversible SERS-active sensing assays made from plasmonic nanoparticles encapsulated in biocompatible matrices have potential as long-term implantable sensors. These assays are encapsulated in "free" form within microdomains bounded by polyelectrolyte multilayers (PEMs), permeable to the target but impermeable to prot…
Os bronzes com alto teor de estanho (20-25 wt.% Sn) são usados na fundição sineira desde a antiguidade. O uso de uma liga com 4 partes de Cu para uma parte de Sn foi proposto como o mais adequado em termos de resistência mecânica e reverberação sonora já no séc. V a.C. na China Antiga. Desde então, esta tem sido a lig…
This paper deals with the computational efficiency related problem appearing in electric power systems adequacy assessment using Monte-Carlo method. When using this method, it is necessary to calculate the steady state for every state from a set of randomly generated states of the simulated system. This task refers to…
Abstract—The cause and the mechanism of formation of a long crack in a linear oil-trunk pipeline section consisting of two longitudinal pipes 1220 mm in diameter made of low-alloy 17G1S steel are comprehensively studied. The length of the crack moving along the longitudinal weld exceeds 3 m. The chemical composition a…
The article developed a mathematical model for calculating the electromagnetic parameters of inductors of special types, for example, inductors with an intermediate conductive medium, inductors-transformers, inductors for heating cylindrical surfaces, when the length of the detail considerably exceeds the length of th…
Abstract—An approach, which is based on modified phenomenological models of the rheological behavior of metallic materials under superplasticity conditions, is proposed to describe the grain size distribution during superplastic flow with allowance for grain refinement. The characteristic features of experimental grai…
