Thermal time

This paper investigates the nonlinear vibration of saturated porous functionally graded plate subjected to the combination of mechanical and thermal loadings. Three different distributions of porosity are considered. Based on the Biot and higher order shear deformation theories, the vibration characteristics including natural frequency, deflection amplitude – time curves and relation between frequency ratio and amplitude of the saturated porous plate are determined.

This study developed a statistical model for thermal analysis to describe the variation of railway temperature that aids in detecting the potential excessive displacement in the railway efficiently. In particular, the Seasonal autoregressive integrated moving average (SARIMA) model is adopted to learn and recognize the variation patterns of railroad temperature with time.

Ebook "Thermal treatments of canned foods" describes the chemical features of canned food products and gives background information on the technology of canning foods. It explains how canned foods are different from other packaged foods, and illustrates and discusses their unique properties, including risks and failures. Canned foods are usually considered to offer a particularly long shelf-life and durability.

Nanostructured materials such as CoPt nanoparticles with tunable hard magnetic properties are desirable for a wide range of technological applications. This study establishes, for the first time, a correlation between the order parameter and the coercivity for annealed CoPt nanoparticles and paves a pathway for the development of nanostructured magnets with tunable magnetic properties.

The control of the spin degree of freedom through the complete understanding of ultrafast phenomena is a central requisite for the development of high-speed spintronic devices. Ultrafast spin dynamics, particularly spin precessions arising after thermal equilibrium among the electron, lattice, and spin systems, have been macroscopically understood and described by the time-dependent interplay of constituent effective magnetic fields.

Although poly-vinyl alcohol (PVA) has certain mechanical drawbacks such as a weak barrier, it has widely been used in food packaging over the last many years. To increase the suitability of PVA (C2H4O)n and render it ideal for food packaging, a diversity of studies have already been carried out. In the below-mentioned script, we, for the first time, report the use of natural product osthol in making a new composite with PVA for enhancing thermal, physicochemical, and antimicrobial properties.

The influence of Na2SO4 as a kosmotropic salt on the thermogelation of xyloglucan (XG) solutions was measured by rheology. The gelation occurred at lower temperatures and shorter times when the salt concentration was increased above 0.5 mol.L−1. For Na2SO4 concentrations equal to 1 mol.L−1, a not thermoreversible elastic hydrogel was obtained.
