“Interior Secretary Rogers C. B. Morton said today the Bureau of Reclamation has awarded a $2,198,895 contract to Convergence Systems, Inc., of Fort Collins, Colorado, for development and operation of a highly instrumented research aircraft and mobile computer van for use by Project Skywater, the Bureau's weather modi…
The creep response of a highly oriented polypropylene tape used for the manufacture of self-reinforced polypropylene or all-polypropylene composites was studied over a range of stresses and temperatures. Similar to oriented polyethylene, the creep compliance is linear viscoelastic at short loading times, whereas prono…
O uso de células para a realização de crescimento celular é chamado de Terapia celular. Esta é o conjunto de métodos e abordagens tecnológicas que utilizam células no tratamento de doenças. A terapia com células-tronco tem despertado grande interesse na comunidade científica devido à capacidade destas células indifere…
It is with great pride and satisfaction that I can close the Proceedings of the VIIth Symposium of Aluminium Surface Science and Technology (ASST), held here in marvelous Madeira Portugal. The reviewed papers have again been presented in a special volume of surface and interface analysis. What started in 1997 in Antwe…
We consider photoemission from cuprate high-temperature superconductors taking into account joint relaxation of strongly coupled fields: a field of correlated electrons and phonon field. Such relaxation occurs in systems with predominantly long-range electron-phonon interaction at sufficiently high carrier concentrati…
The Front Cover shows a formation of covalent triazine framework (CTF) based spheres using commercially available polyimide as a binder. In their Full Paper, A. V. Bavykina et al. present a facile one-step method to shape CTFs into composite spheres with accessible porosity, high mechanical, and thermal stability. The…
Abstract With the increase in the world population, increases in scientific and industrial activities have engendered spontaneous upsurge in the global demand for oil and gas in the past few years. These resulted in depletion of major world oil reservoir without corresponding discovery of new major oil fields. However…
Les liquides confinés présentent beaucoup de comportements fascinants, très différents de ceux qui sont observés dans leur volume. Le confinement peut induire un déplacement de l'équilibre des phases (par exemple de la transition liquide-vapeur, aussi appelé condensation capillaire), il peut modifier la température de…
We observed strongly size-dependent viscoelasticity in amorphous SiO2 and Si nanotubes with shell thickness down to ~8 nm. A core-shell model shows that a ~1 nm thick fluid-like surface layer has a significant effect on the mechanical behavior of nanotubes and matches well with our experimental results. Surprising, th…
We study the winding angles of random and self-avoiding walks (SAWs) on square and cubic lattices with number of steps N ranging up to 10(7). We show that the mean square winding angle 〈θ(2)〉 of random walks converges to the theoretical form when N → ∞. For self-avoiding walks on the square lattice, we show that the r…
Hochauflösende Röntgenspektrospie stellt ein wichtiges Werkzeug zum Studium der komplexen Vorgänge in den inneren Schalen der Atome dar. Die Effekte solcher Wechselwirkungen sind besonders stark ausgeprägt im Bereich der 3d-Übergangselemente. Bei den K-beta-Übergängen sind spektroskopische Methoden weit verbreitet, um…
Let $X\in\mathbb{C}^{m\times m}$ and $Y\in\mathbb{C}^{n\times n}$ be nonsingular matrices, and let $N\in\mathbb{C}^{m\times n}$. Explicit expressions for the Moore-Penrose inverses of $M=XNY$ and a two-by-two block matrix, under appropriate conditions, have been established by Castro-González et al. [Linear Algebra Ap…
The Cover shows a representative idea of methane to syngas conversion. Energy/fuel related industrial catalysis occurs at high to very high temperatures. A fundamental understanding of them might lead to develop better catalysts to work under milder conditions. C−H activation is a perennial issue and a surprise was wa…
This workshop, entitled The Cytoskeleton: Mechanical, Physical, and Biological Interactions, was sponsored by the Center for Advanced Studies in the Space Life Sciences at the Marine Biological Laboratory. This Center was established through a cooperative agreement between the MBL and the Life Sciences Division of the…
Despite their extreme morphologies, snakes display a global regulatory strategy of their Hox genes similar to that implemented by mammals with, however, important modifications in enhancer specificity.
The possibility of creating superconductivity in Highly Oriented Pyrolytic Graphite (HOPG) by means of doping was investigated. Bulk HOPG samples were doped with phosphorous using either ion-implantation or by Chemical Vapor Deposition growth with phosphine in the gas mixture. The methods for testing the graphene samp…
Chromium dioxide CrO$_2$ belongs to a class of materials called ferromagnetic half-metals, whose peculiar aspect is to act as a metal in one spin orientation and as semiconductor or insulator in the opposite one. Despite numerous experimental and theoretical studies motivated by technologically important applications…
Preparing for first DOI publication.
Many features of charge-4e superconductors remain unknown because even the "mean-field Hamiltonian" describing them is an interacting model. Here we introduce an interacting model to describe a charge-4e superconductor (SC) deep in the superconducting phase, and explore its properties using quantum Monte Carlo (QMC) s…
O aço inoxidável martensítico ASTM A743 CA6NM é utilizado para produzir componentes especiais para turbinas hidráulicas, devido às suas boas propriedades mecânicas combinadas com alta resistência à corrosão e cavitação e uma boa soldabilidade.As turbinas hidráulicas são produzidas por meio de múltiplos passes de solda…
