“…Thin-layer chromatography (TLC). The lipid classes of the fungal oil and its separated fractions (CF, LF) were determined with TLC using the one-dimensional double development procedure of Freeman and West (18), with some modification (19) using two solvent systems. Composition of solvent system I was benzene/diethyl ether/ ethanol/28% ammonium water (50:40:2:0.5, v/v/v/v), and that of solvent system II was n-hexane/diethyl ether (94:6, v/v), respectively.…”

The fungal oil extracted from Mortierella ramanniana var. angulispora (IFO 8187) was solvent winterized in order to raise the content of 7-1inolenic acid (GLA). Effects of winterization conditions (solvent, oil concentration in the solvent and temperature) and changes of glyceride compositions were discussed. The fungal oil was separated into four diglycerides and 17 triglycerides (TG) with high performance liquid chromatography. The predominant species were POO, POP and LOP, whose contents were 24.4, 22.9 and 9.4% of the total TG, respectively. Ethanol at 4~ gave the highest GLA content of 10.5% in spite of lower yield than with acetone at -20~The highest separation efficiency for GLA (~GLA) was 0.27 with acetone at -20~ and 10% oil concentration, resulting in 8.3% of GLA from the fungal oil at 5.7% GLA. In case of lower oil concentration at 5-20%, ~GLA showed higher in the following order: acetone (-20~ ~ nhexane (-20~ ~ acetone (4~ ~ petroleum ether (-20~The winterization process also proved to be effective for the separation of TG type, Sa2U (Sa; saturated fatty acid; U, unsaturated fatty acid) into the crystallized fraction and SaU 2 into the liquid fraction. Acetone at -20~ showed higher separation efficiency for triunsaturated TG than the other solvents.

“…The de Haas-van Alphen effect was studied for LaIn 3 [11], YIn 3 [12] and antiferromagnetic GdIn 3 [13]. A few theoretical studies of the electronic structure of LaIn 3 [14][15][16] are also available. Many studies on the physical properties of LaB 3 (B = In, Tl, Sn Pb) and their alloys have been reported earlier [2,3,[17][18][19], but no theoretical study comparing the electronic structures of AB 3 (A = La, Y and B = In, Tl, Pb) at ambient or at high pressure is available.…”

The electronic structures, densities of states, Fermi surfaces and elastic properties of AB3 (A =La, Y; B =Pb, In, Tl) compounds are studied under pressure using the full-potential linear augmented plane wave (FP-LAPW) method within the local density approximation for the exchange-correlation functional and including spin-orbit coupling. Fermi surface topology changes are found for all the isostructural AB3 compounds under compression (at V/V0 = 0.90 for LaPb3 (pressure = 8 GPa), at V/V0 = 0.98 for AIn3 (pressure = 1.5 GPa), at V/V0 = 0.80 for ATl3 (pressure in excess of 18 GPa)) apart from YPb3, although its electronic structure at zero pressure is very similar to that of LaPb3. For LaPb3 a softening of the C44 elastic constant under pressure (equivalent to 8 GPa) may be related to the appearance of a new hole pocket around the X point. From the calculated elastic properties and other mechanical properties, all the compounds investigated are found to be ductile in nature with elastic anisotropy. The states at the Fermi level (EF) are dominated by B p states with significant contributions from the A d states. For the La compounds, small hybridizations of the La f states also occur around EF.

“…We present below a brief numerical example chosen to illustrate the potential use of the ideas discussed in the previous section in study of quantum dynamics. We examine a model system [16] that consists of a single moving particle trapped on a line between two space-fixed particles (separated by a distance L) that act as a Rcage.S The particle whose dynamics is of interest is assumed to interact with the fixed atoms through pairwise Lennard-Jones potentials. These potentials as well as the cage dimensions can be varied to probe the behavior of various prototypical systems.…”

In the present paper we examine the effects of noise on Monte Carlo algorithms, a problem raised previously by Kennedy and Kuti (Phys. Rev. Lett. 54, 2473 (1985)). We show that the effects of introducing unbiased noise into the acceptance/rejection phase of the conventional Metropolis approach are surprisingly modest, and, to a significant degree, largely controllable. We present model condensed phase numerical applications to support these conclusions.
