Powered options for alternative power supply equipment at nuclear power blackout. The calculation of core damage frequency VVER-1000 reactor core for initiating events considering the options. The aim of this work is to study the existing deficit reliability provide electricity main elements influencing the risk in a…
Discusses aspects of labor adaptation of young professionals. With the technology of sociology we study the adaptation of young professionals in the field of civil aviation, which allowed to identify the factors of professional development of young professionals such as: training, mentoring, independence and interest…
Epoxy compatible P(St-co-GMA) copolymer based nanofibrous mats are introduced by electrospinning onto uni-directional (UD) and 0/90 twill weave carbon fiber/epoxy prepreg systems as interlayers. Anticipated in-plane strength improvement via higher matrix cracking resistance at the free edges, nanofibrous interlayered…
Analytical models of the magnetic field enhancement at pits were presented at SRF2013 last year*. Other simple models will be addressed in this paper.

The mechanism of human fibronectin adhesion synergy region (known as integrin binding region) in repeat 9 (FNᴵᴵᴵ9) domain adsorption at pH 7 onto various and contrasting model surfaces has been studied using atomistic molecular dynamics simulations. We use an ionic model to mimic mica surface charge density but withou…
The problem of toughness in a heat affected zone of welded joints of submerged arc welded pipes with high wall thickness is discussed in this article. The greatest toughness failure was observed in coarse grains of the heat affected zone (CGHAZ) adjacent to the fusion line. This is due to significant structural change…
Three different magnetic samples with particle sizes ranging from 10 to 30 nm were prepared by wet chemical methods. The powders were heated at 100, 150, 200, and 250 °C during 30 min under air. Ferrous and total iron contents were determined immediately after the synthesis and after the thermal treatments. All sample…
Manufactured silver nanoparticles (AgNP) are among the most widely used nanoparticles in consumer products and their unintended release to soils has become a serious concern. For a meaningful assessment of the environmental risks of AgNP in soils, their concentration and particle-size-distribution in soil pore water n…
The succession of suggested mechanisms of solid-state phase transitions − Second-order, Lambda, Martensitic, Displacive, Topological, Order-Disorder, Soft-mode, Incommensurate, Scaling and Quantum − are analyzed and explained why they cannot be realized in nature. All of them assume a cooperative structural rearrangem…
This poster presents information about the nuclear reactor crisis at Fukushima Daiichi on March 11, 2011.
To enhance heat transfer performance of epoxy resin as a thermal interface material (TIM), multi-walled carbon nanotubes (MWCNTs) and nano-copper particles are incorporated into an epoxy resin to form hybrid composites. The total thermal contact resistance (TCR) between the heated and cooled surfaces as well as its co…
CA 모사 촉매 개발 간단한 N3 리간드(dipicolyamine)를 polystyrene beads의 표면에 부착하여 아연금속과 배위를 통해 새로운 hybrid 촉매를 합성하였다. 이를 FE-SEM, FT-IR, TGA 그리고 EA로 분석하였다. 새로운 hybrid 촉매는 이합체의 형성을 방지할 수 있었고 분리가 용이한 장점을 가지고 있다. 포화된 이산화탄소 용...
Microelectronic-grade copper foils were immersion silver plated in a home-made non-cyanide alkaline silver nitrate thiosulfate solution and in two commercially available industrial baths via contact reductive precipitation. The concentration depth profiles of the freshly deposited silver layers were afterwards analyze…
Molecular dynamics simulations have been performed to investigate the structures of Lennard—Jones (LJ) nanowires (NWs) encapsulated in carbon nanotubes (CNTs). We find that the structures of NWs in a small CNT only adopt multi-shell motifs, while the structures of NWs in a larger CNT tend to adopt various motifs. Amon…
Introdução e Objetivos. A proteína desacopladora 2 (UCP2) diminui a produção de espécies reativas de oxigênio (ROS) pela mitocôndria. A superprodução de ROS é um dos maiores contribuintes para a patogênese de complicações crônicas do diabetes, como a doença renal do diabetes (DRD). Assim, polimorfismos deletérios no g…
We study network design with a cost structure motivated by redundancy in data traffic. We are given a graph, g groups of terminals, and a universe of data packets. Each group of terminals desires a subset of the packets from its respective source. The cost of routing traffic on any edge in the network is proportional…
We consider the random Schrödinger operator on a large box in the lattice with a large prefactor in front of the Laplacian part of the operator, which is proportional to the square of the diameter of the box. The random potential is assumed to be independent and bounded; its expectation function and variance function…
Superparamagnetic iron oxide nanoparticles (SPIONs) with a mixed phase composition (γ-Fe₂O₃)₁–ₓ(Fe₃O₄)ₓ and sizes between 9 and 20 nm were synthesized via coprecipitation and were either left uncoated or subsequently surface-stabilized with citrate or malate anions. The sizes, morphology, surface chemistry, and magnet…
We study a diffuse interface model for incompressible isothermal mixtures of two immiscible fluids coupling the Navier-Stokes system with a convective nonlocal Cahn-Hilliard equation in two dimensions of space. We apply recently proved well-posedness and regularity results in order to establish existence of optimal co…
