  • Thermal expansion property of three-phase fiber composite material reinforced by spherical particles is one of important properties of this material. In this paper, we would like to propose a way in order to determine thermal expansion coefficients of three-phase composite reinferced by fibres and spherical particles. Keywords: thermal expansion coefficients, three-phase composite material, aligned fibres, spherical particles, effective matrix phase.

  • Two major approaches to cryopreservation are known, i.e., conventional freeze-thaw procedures and vitrification, which is defined as a glass-like solidification (Karlsson & Toner, 1996). While freeze-thaw procedures minimize the probability of intracellular ice formation, vitrification attempts to prevent ice formation throughout the entire sample during the cooling and warming process (Kuleshova et al., 2007). Recently, the potential of vitrification has been tested for tissue-engineered constructs.

  • This paper presents some thermomechanical characteristics of crosslinked poly(vinyl chloride) (PVC) samples such as glass transition temperature (Tg), softening point (Ts), and linear thermal expansion coefficient ( ). Probe load of 0.05 N is most suitable to evaluate expansion, softening and contraction of the crosslinked PVC samples. Tg , Ts and of the crosslinked PVC samples are higher than those of the uncrosslinked samples.

  • Non-Electric Thermometers 2.1 Liquid-in-Glass Thermometers Liquid-in-glass thermometers are based upon the temperature dependent variation of the volume of the liquid which is used . The thermometer consists of a liquid filled bulb connected to a thin capillary with a temperature scale as shown in Figure 2.1 . Assuming that the bulk volume, Vb, is much greater than that of the liquid contained in the capillary, the volume variation, AV, of the liquid corresponding to the measured temperature variation, d6, is: AV = V/3.;AO (2.

  • The great advantage of using panel data over a simple cross-sectional sample is that one can control for the country-specific fixed effects ai. Failure to do so leads to biased estimates if these fixed or latent effects are correlated with the explanatory variables, as is likely to be the case. However, unfortunately the use of panel data also leads to more compli- cations if some or all of the variables in the estimating equation follow a trend over time. Such trending typically implies what econometricians call non-stationarity.

  • Anharmonic effective potential, effective local force constant, thermal expansion coefficient, three leading cumulants, and EXAFS (Extended X-ray Absorption Fine Structure) of hcp crystals have been studied. Analytical expressions for these quantities have been derived. Numerical calculations have been carried out for Zn and Cd. They show a good agreement with experiment results measured at HASYLAB (DESY, Germany) and unnegligible anharmonic effects in the considered quantities.
