Mapping of non-central potentials under point canonical transformations

Motivated by the observation that all known exactly solvable shape invariant central potentials are inter-related via point canonical transformations, we develop an algebraic framework to show that a similar mapping procedure is also exist between a class of non-central potentials. As an illustrative example, we discuss the inter-relation between the generalized Coulomb and oscillator systems.Comment: 11 pages article in LaTEX (uses standard article.sty).

The possibility of using fluid whey in comminuted meat products: capacity and viscosity of the model emulsions prepared using whey and muscle proteins

The emulsion capacity (EC) of whey and sarcoplasmic proteins were low when they were used alone, but the EC and viscosity (EV) of total meat proteins (TMP) were higher than those values of other proteins investigated, including a combination of whey plus TMP. However, the solubility of the TMP proteins was lower than that of the other proteins investigated, probably due to the differences in the physico-chemical properties of whey and muscle proteins and the buffer used. In general, EC of whey proteins showed a significant alteration when used in combination with muscle proteins, while its solubility was not changed. The present results suggest that it is possible to use fluid whey in emulsion-type meat products and these studies should continue using actual meat emulsion systems. © 1995 Springer-Verlag

Far infrared properties of PbTe doped with Hg

Single crystal samples of PbTe doped with Hg were grown using the Bridgman method. Far infrared reflectivity spectra were measured at room temperature for samples with 0.5 at. % Hg; 0.9 at. % Hg and 1.4 at. % Hg. The plasma frequency decreased when PbTe was doped with Hg and it was lowest for the PbTe sample doped with 0.5 at. % Hg. The values of the determined optical free carrier mobility increased and was the highest for PbTe doped with 0.5 at. % Hg

Far infrared and photoacoustic characterization of iodine doped PbTe

Single crystal samples of PbTe doped with PbI2 were made using the Bridgman technique. Far infrared reflectivity diagrams of PbTe doped with 0.4 at% and 0.6 at% Iodine were measured and numerically analyzed. A plasma resonance at about 650 cm(-1) with the reflectivity minima very close to zero was observed for both samples. Thermal diffusivity was determined for the same samples using the photoacoustic method with a transmission detection configuration and the values of the minority free carrier (holes) mobility were calculated

Optical far infrared properties of PtSb2

Far infrared reflection spectra measured at room temperature were used to investigate vibrational properties of PtSb2 single crystals. The experimental results were analyzed using a dielectric function taking into account the existence of plasmonionised impurity-phonon interactions. Together with strong coupling three infrared active lattice modes at about 143, 187 and 202 cm-1 were observed. These results were discussed with respect to calculated literature vibrational frequencies. Electrical properties of single crystal PtSb2 were also measured at room temperature
