The antagonizing action of hydrostatic pressure against anesthesia is well known. The present study was undertaken to quantitate the effects of hydrostatic pressure and anesthetics upon the phase-transition temperature of dipalmitoyl phosphatidylcholine vesicles. The drugs used to anesthetize the phospholipid vesicles included an inhalation anesthetic, halothane, a dissociable local anesthetic,...

A special plasticity-based constitutive model with an up–down–up flow rule used within a finite element framework has previously been shown to simulate the inhomogeneous nature and the thermo-mechanical coupling of stress-induced transformation seen in a NiTi shape memory alloy. This paper continues this numerical study by investigating the trends of localized nucleation and propagation phenome...

We subjected succinonitrile dendrites growing under steady-state conditions to a rapid change in thermal driving force through a step-change in pressure. This change in pressure caused a corresponding change in the equilibrium melting temperature due to the Clapeyron effect, and a shift in the temperature field due to an adiabatic temperature change in both the solid and its melt. The new therm...

Adsorption and desorption isotherms of fresh and dried Cape gooseberry (Physalis peruviana L.) were determined at three temperatures (20, 40 and 60 °C) using a gravimetric technique. The data obtained were fitted to several models including Guggenheim-Anderson-De Boer (GAB), Brunauer-Emmett-Teller (BET), Henderson, Caurie, Smith, Oswin, Halsey and Iglesias-Chirife. A non-linear least square reg...

The problem of high-frequency acoustic emission generated by a spherical hot liquid drop in a cool ambient liquid (water) is considered analytically. It is assumed that the acoustic emission is generated by the motion of the vapor cold liquid interface, which is described by the Rayleigh equation for a spherical bubble. It is also assumed that the linear relationship between the saturated press...

[1] The recently discovered phase transition for (Mg,Fe)SiO3 from perovskite to post-perovskite structure for pressure-temperature conditions in the lowermost mantle provides a plausible mechanism to explain a several percent shear velocity increase detected at the top of the D00 region in many regions. The phase transition has a large positive Clapeyron slope, and given the likely presence of ...

Atmospheric concentrations of organochlorine pesticides (OCPs) have been measured for the first time at Station Nord, North-East Greenland, from 2008 to 2010. The data obtained are reported here. Hexachlorobenzene (HCB), endosulfan I and hexachlorocyclohexanes (HCHs) were the predominant compounds detected in the atmosphere, followed by p,p'-DDE and dieldrin. Chlordane isomers and related compo...

The interest in using the pseudoelastic properties of NiTi wires in orthodontic practice arises chiefly from the expectation that they can afford low continuous forces at constant temperature. The reversion force developed by NiTi archwires depends, however, upon temperature since the superelastic force follows a Clausius-Clapeyron like equation. Actually the oral environment temperature is mod...

The aim of this project is to make up a comprehensive model of the dynamics and evolution of the Earth's mantle, and to simulate phenomena related with subduction. (1) With the global modeling in Earth-like spherical shell geometry, we made systematic research on the convection patterns for the wide range of Rayleigh numbers with phase transitions. The experimentally and seismologically plausib...

Raman spectroscopy is used to examine the effects of temperature, surface coverage, nature of the alkylsilane precursor (octadecyltrichlorosilane, methyloctadecyldichlorosilane, or dimethyloctadecylchlorosilane), and surface grafting method (surface or solution polymerized) on alkyl chain conformational order in a series of high-density octadecylsilane stationary phases ranging in surface cover...
