O objetivo do presente estudo é a procura de evidências da presença de modos GAM nas descargas do tokamak TCABR, em distintos regimes de operação. As descargas selecionadas foram classicadas segundo a maneira de obter a melhora no connamento do plasma. Nós zemos essa procura nas descargas ôhmicas com incremento espont…
In recent years the research on new materials for application in construction had intensified in order to rationalize the manpower in the sector. Thereat, many studies are being conducted with the goal of developing composites for use in construction. The use of composites as wall panels is sustainable when the materi…

La fissuration à chaud de solidification qui est l'un des problèmes majeurs rencontrés dans le cadre du soudage pourrait être préjudiciable à la tenue en service de structures mécano-soudées. Ce phénomène correspond à la formation de fissures en fin de solidification sous l'effet des déformations induites par les cont…
La synthèse de macroalcoxyamines hydrosolubles à partir d’acide méthacrylique et d’un faible pourcentage de styrène sulfonate de sodium a été étudiée en solution aqueuse. Ces macroalcoxyamines ont été utilisées comme macroamorceurs pour la polymérisation en émulsion sanstensioactif du méthacrylate de méthyle et du mét…

Abstract Invited for the cover of this issue are Scott Mitchell and Jesús Martínez de la Fuente of The Nanotherapy and Nanodiagnostics Group from the Institute of Nanoscience of Aragón, part of the University of Zaragoza (Spain). The cover image shows a false colored SEM image of triangular gold nanoprisms (we refer t…
Guillaume Amontons This chapter introduces the essential tribological concepts of surfaces, lubrication, friction and wear, each of which plays a critical role in the performance and reliability of machine elements. Surfaces are investigated in detail, including common definitions to quantify roughness and a general d…
This specification establishes the requirements for copper alloy strips for use in the manufacture of electrical connectors or spring contacts produced from one of the following Copper Alloy UNS Nos.: C14530, C15100, C15500, C17000, C17200, C17410, C17450, C17460, C17500, C17510, C19010, C19025, C19210, C19400, C19500…
This chapter begins by listing the material parameters and partial safety factors for structural element resistances. Then, bearing capacities for soldier pile infilling, soldier piles, sheet piles, in-situ concrete walls, waling, struts, trench lining, provisional bridges and excavation covers are discussed. For anal…

Water-soluble, SG1-based macroalkoxyamines composed of methacrylic acid with a low percentage of sodium 4-styrene sulfonate were synthesized in aqueous solution. These macroalkoxyamines were used as macroinitiators in the surfactant-free emulsion polymerization ofmethyl methacrylate or n-butyl methacrylate with a low…
Saphenous vein (SV) graft disease represents an unresolved problem in coronary artery bypass grafting (CABG). After CABG, a progressive remodeling of the SV wall occurs, possibly leading to the lumen occlusion. This process is termed intima hyperplasia (IH). The investigation of cellular and molecular aspects of IH pr…
