ISSN: 1432-0630Keywords: 79.20.Hx ; 79.20.KzSource: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsPhysicsNotes: Abstract The intensity profile for the elastic specular reflection of 5–100 eV positrons from a LiF(100) surface (ang1e of incidence 45°) has been measured using a simple time-of-flight spectrometer. The profile exhibits strong maxima below 25 eV and a smaller peak at 57 eV. Positron energy loss spectra have also been measured for a range of incident energies by retarding field analysis of the scattered beam. The mean energy loss appears to increase with increasing incident beam energy. Both the elastic and inelastic results are compared with similar data for slow-electron scattering obtained with the same apparatus.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-1041Keywords: ketamine ; binding to plasma proteins ; alpha1-acid glycoprotein ; albumin ; pH changeSource: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyMedicineNotes: Summary We report for the first time that ketamine (K) is bound as much as 47% to human plasma. It was shown that binding of K to plasma and albumin is dependent on pH; binding is decreased at pH lower than 7.4 and increased at higher pH. This is in concordance with the pKa of K being 7.5; the partition coefficient between an organic phase and buffer was found to be sensitive to small pH changes. Binding of K is also influenced by albumin concentration and the affinity of K for human α1-acid glycoprotein (AAG) is much higher than for human albumin (HSA). The major metabolite nor-K does not appreciably displace K from binding sites on HSA. These findings may explain in part the variability of binding of K observed with different human samples. Human cord plasma exhibits a lower binding of K than adult plasma. This is probably the result of much lower AAG concentration in cord compared to adult plasma; cord and adult plasma albumin levels are known to be only slightly different. Since K has 2 optically active isomers, one of which is more potent than the other, experiments on the binding of racemic and the 2 isomers of K were performed; no differences in binding to AAG were found. We were, however, able to show that tris (butoxyethyl) phosphate (TBEP) can abolish binding of K to AAG. Thus the presence of TBEP would interfere in determining plasma levels and distribution of K. An example would be in the measurement of the partition of K between human red cells and plasma. We determined this ratio in human blood in the absence of TBEP and found it to be similar to that reported for dog red blood cells and plasma.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-1472Source: Springer Online Journal Archives 1860-2000Topics: GeosciencesPhysicsNotes: Abstract Eddy-correlation measurements of the vertical fluxes of ozone, carbon dioxide, fine particles with diameter near 0.1 Μm, and particulate sulfur, as well as of momentum, heat and water vapor, have been taken above a tall leafless deciduous forest in wintertime. During the experimental period of one week, ozone deposition velocities varied from about 0.1 cm s−1 at night to more than 0.4 cm s-1 during the daytime, with the largest variations associated primarily with changes in solar irradiation. Most of the ozone removal took place in the upper canopy. Carbon dioxide fluxes were directed upward due to respiration and exhibited a strong dependence on air temperature and solar heating. The fluxes were approximately zero at air temperatures less than 5 °C and approached 0.8 mg m−2 s−1 when temperatures exceeded 15 °C during the daytime. Fine-particle deposition rates were large at times, with deposition velocities near 0.8 cm s−1 when turbulence levels were high, but fluxes directed upward were found above the canopy when the surface beneath was covered with snow. Diffusional processes seemed to dominate fine-particle transfer across quasilaminar layers and subsequent deposition to the upper canopy. Deposition velocities for particulate sulfur were highly variable and averaged to a value small in magnitude as compared to similar measurements taken previously over a pine forest in summer.Type of Medium: Electronic ResourceURL: -

The library consists of 30 720 clones with an average insert size of approximately 100 kb, representing approximately five haploid-genome equivalents. The frequency of BAC clones carrying inserts of chloroplast DNA was estimated to be 1.4%. Screening of the library with single- or low-copy genes as hybridization probes resulted in the detection of 1–12 clones per gene. Hybridization of the library with repeated sequences such as rDNA genes and transposon-like elements of M. truncatula revealed the presence of 60 and 374 BAC clones containing the two sequences, respectively. The BAC library was pooled for screening by polymerase chain reaction (PCR)-amplification. To demonstrate the utility of this system, we used primers designed from a conserved region of the ein3-like loci of Arabidopsis thaliana and isolated six unique BAC clones from the library. DNA gel-blot and sequence analyses showed that these ein3-like clones could be grouped into three classes, an observation consistent with the presence of multiple ein3-like loci in M. truncatula. These results indicate that the BAC library represents a central resource for the map-based cloning and physical mapping in M. truncatula and other legumes.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-1472Source: Springer Online Journal Archives 1860-2000Topics: GeosciencesPhysicsNotes: Abstract Eddy-correlation measurements over snow, wet bare soil, and lake water indicate very small vertical ozone fluxes. Adjustments to the small vertical fluxes are needed to take into account the effect of mean Stefan flow associated with evaporation at the surface and the effects of correlation between density variations and vertical wind fluctuations. For snow, the residual resistance calculated for the surface is about 34 s cm-1, indicating that the maximum deposition velocity is abut 0.03 cm s-1. For cold bare soil well saturated with water, the surface resistance is about 10 s cm-1 (maximum deposition velocity of about 0.1 cm s-1). The highest resistances obtained are for transfer to the surface of Lake Michigan, yielding values near 90 s cm-1 for resistance (0.01 cm s-1 for deposition velocity).Type of Medium: Electronic ResourceURL:
