The transport properties of a fluid show complex dependence with temperature and pressure due to the combination different phenomena occurring at microscopic scale. entropy scaling concept aims describing this behavior by expressing reduced as one-variable functions Tv-residual entropy, thermodynamic quantity that can be straightforwardly estimated an equation state (EoS). In work, reformulated...

Friction stir welding (FSW) is a recently developed solid-state joining process that uses a specially shaped rotating tool to produce lap or butt joints. At the National Research Council, an inter-institute collaboration was started in 2007 with the goal of exploiting the NDE expertise and applying it for the characterization of friction stir welds for various industrial applications. In partic...

The use of lignocellulosic biomass in the chemical industry can significantly contribute to respect various international agreements on climate change. One most promising platform molecules issued from hydrolysis is ?-valerolactone (GVL). GVL be upgraded valuable chemicals and produced by hydrogenation alkyl levulinates. Although these reactions are widely studied, seldom research focused solve...

the aim of this study was to determine the effect of trenched zirconia bar on the von mises stress distribution of ips -empress ii core ceramics.the three-dimensional model including a three-unit bridge from the second premolar to the second molar was designed. the model was reinforced with zirconia bar (zb), zirconia bar with vertical trench (vzb) and zirconia bar with horizontal trench (hzb) ...

Abstract Corrosion in reinforced concrete (RC) structures is associated with a reduction of the rebar diameter, loss interfacial bond, cracking, and eventual spalling probable collapse structure. The negative effects corrosion on structural safety, durability, longevity imposes significant costs national economy. Therefore, planned non-destructive testing (NDT) essential to enhance safety econo...

Ž . In this work, we apply the Gibbs–Duhem integration GDI technique to obtain the vapor–liquid equilibrium Ž . VLE properties of hydrogen fluoride according to three potential models. Properties examined include coexistence densities, enthalpy of vaporization, and vapor pressure. The models are representative of the various types of potentials used in simulation studies; namely, a pure pair po...

Many applications have stimulated the recent surge of interest single-chip parallel processing. In such machines, it is crucial to implement a high-throughput low-latency interconnection network to connect the on-chip components, especially the processing units and the memory units. In this paper, we propose a new mesh of trees (MoT) implementation of the interconnection network and evaluate it...
