The rational design of welded and brazing nodes with soft interlayers is discussed. The research aim is to determine the regularities of influence of the relative thickness and the degree of elongation of soft interlayers on the formation of the stress-strain state of the welded and brazing joints in the elastic defor…
Metals in aqueous environment usually corrode with electrochemical reactions. Electrochemical reactions that occur in metal/electrolyte interface are quite complex. Because of that complexity, many electrochemical methods are developed to determine corrosion process
This paper is presented a new theoretical model basis on experimental to predict the thrust force on AZ91magnesium alloy in drilling process depend on the various machining parameters. The experiments for modeling were conducted in dry cutting conditions and designed as full factorial using the spindle speed and feed…
Polymer materials are engineering materials used for various industrial fields. Polymer processing and fabrication techniques have developed with the advancement of technology. Friction Stir Spot Welding (FSSW) is a solid-state process in joining thermoplastic materials. In the present work, the polymeric material (Po…
One of the most significant issues related to the safety of high voltage power cables is the degradation of their parts and materials. The performance of the power cables depends on the mechanical and electrical integrity of the insulator material. Micro-cracks in high voltage power cables can threaten the insulating…
In this study, the axial tensile stress formulas in the steel plates were determined by classical and photoelasticity methods. Fe37 steel sheets were used for the experimental work. Photoelastic coating was applied on the steel sheets. Strain-optic coefficient of the coating material calibrated and fringe (number of l…

[pt] Treliças espaciais de forma piramidal são um componente básico de diversas estruturas, incluindo desde nanoestruturas de carbono até domos geodésicos para cobertura de grandes espaços. Estas estruturas, tal como a treliça plana de von Mises, apresentam uma resposta altamente não linear na presença de cargas estát…
Nanocrystals with a β-NaGdF4/Na(Gd,Yb)F4:Er/NaYF4:Yb/NaNdF4:Yb core/shell 1/shell 2/shell 3 structure were synthesized and used as probes for in vivo bioimaging. F. Zhang et al. explain in their Communication on page 12086 ff. that the nanocrystals can be excited by near-infrared (800 nm) radiation and emit short-wave…
In this erratum we have replaced the wrong figures and corrected several misprints that were found in our recently published paper [J. Opt. Soc. Am. B 31, 1822 (2014)].
Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species.
A weekly roundup of information on newly offered instrumentation, apparatus, and laboratory materials of potential interest to researchers.
Nowadays there is great empathy from society for products from renewable resources, due to growing awareness of the finiteness of natural resources. A very common residue of agribusiness and generated on a large scale, being largely discarded in landfills, is coconut shell. With the objective of giving a benefit to th…
An der Elektronen-Stretcher-Anlage ELSA des Physikalischen Instituts der Universität Bonn werden derzeit hadronenphysikalische Doppelpolarisationsexperimente im Rahmen des transregionalen Sonderforschungsbereichs SFB/TR 16 "Elektromagnetische Anregung subnuklearer Systeme" durchgeführt. Der für diese Untersuchungen be…
Electrochemical reduction of CO2 to form useful chemicals or fuels is a potentially efficient method of CO2 utilization and recycling [1], particular to liquid fuels (for example HCOOH or HCOO-),whcih could offer a carbon neutral solution for a variety of energy applications. For large-scale conversion of CO2 to fuels…
Depuis ces dernieres annees, de plus en plus de molecules-candidates entrees dans le pipelinedes industriels pharmaceutiques ont un probleme de solubilite dans l'eau. D'apres differentsauteurs, le pourcentage des candidats faiblement solubles dans l'eau est de l'ordre de 60%-75%. Plusieurs approches galeniques sont ma…
An exact mapping of the tight-binding Hamiltonian for a graphene's nanoribbon under any armchair uniaxial strain into an effective one-dimensional system is presented. As an application, for a periodic modulation we have found a gap opening at the Fermi level and a complex fractal spectrum, akin to the Hofstadter butt…
