    Description / Table of Contents: Zusammenfassung Der Polymorphismus des Locus D1S80 wurde in einer Bevölkerungsstichprobe von 203 unverwandten, in Madrid lebenden Personen unter-sucht. Die Untersuchung erfolgte mit Hilfe der PCR und nachfolgender, halbtrockener diskontinuierlicher Polyacrylamidgel-Elektrophorese (Tris-chlorid/Tris-glycin-Puffersystem) mit nachfolgender Silberfärbung. Das beschriebene elektrophoretische System dieser Untersuchung bietet eine hohe Auflösung in der Auftrennung der verschiedenen D1S80-Allele und erlaubt den Nachweis einer Mikrovariabilität um das Allel T22 in der spanischen Bevölkerung, welche zwischen 17 und 40 Wiederholungseinheiten der zugrunde liegenden 16 Bp-Einheit enthalten. Die Allele T18 and T24 wurden als relativ häufig in Spanien gefunden, wie auch in anderen Populationen, mit Frequenzen von 0,224 bzw. 0,372. Es fand sich kein Beweis für signifikante Abweichungen vom Hardy-Weinberg-Gleichgewicht in dieser vorläufigen Populationsstudie.
    Notes: Summary The polymorphism of the D1S80 locus has been analyzed in a population sample of 203 unrelated individuals living in Madrid (central Spain) by PCR and subsequent semi-dry discontinuous polyacrylamide gel electrophoresis (Tris-chloride/Tris-glycine buffer system) followed by silver staining, The electrophoretic system described in this study offers high resolution in the separation of the different D1S80 alleles allowing the detection of microvariability around the allele T22 in the spanish population. Twenty different alleles containing 17–40 repeats of the basic 16bp unit were distinguished. The alleles T18 and T24 were found to be relatively common in Spain, as in other populations:, with frequencies of 0.224 and 0.372, respectively. No evidence of significant deviations from Hardy-Weinberg equilibrium was found in these preliminary population data.

    Notes: Abstract Blood samples from 202–208 unrelated Basque Country autochthonous individuals were amplified, typed and their allele frequencies were determined. Results demonstrate the assumption of independence within and between the loci analyzed. Therefore, a Basque population database can be used in identity testing to estimate the frequency of a multiple PCR-based locus DNA profile.

    Notes: Abstract Population data were generated for four tetrameric short tandem repeat loci systems (D8S1179, D16S539, D18S51 and D21S11) for a Spanish Caucasian population sample (n = 218–219 individuals) using PCR. All loci were highly polymorphic, met Hardy-Weinberg expectations and the results demonstrated the assumption of independence of the loci analysed. The allele frequency data can be used in identity testing to estimate the frequency of a multiple PCR-based DNA profile in the Spanish population.

All loci met Hardy-Weinberg expectations and the results demonstrated the assumption of independence of the loci analysed. The allele frequency data can be used in identity testing to estimate the frequency of a multiple PCR-based DNA profile in the Spanish population.

    Notes: Novel EPDM (ethylenepropylenediene monomer) and polybutadiene polyols can be synthesized by a two-step process of controlled hydroformylation and then reduction of the formyl groups to place a desired amount of pendant alcohol groups along the polymer chain. The degree of functionalization can be controlled by measuring gas uptake from a calibrated reservoir during hydroformylation. Hydroformylation can be performed in solution or under simulated melt-phase conditions using either HRh(CO)(PPh3)3 or Rh(acac) (CO)2 as catalysts. Reduction of the polyaldehyde by NaBH4 generates the polymeric alcohol without further reaction of the remaining double bonds. Polymer functionalization and further modifications were followed by H-NMR and FTIR. These unique hydrophobic polyols can be reacted further to produce other polymer systems. As an example, urethanes have been made with these polyols by reaction with diisocyanates. © 1995 John Wiley & Sons, Inc.

    Notes: The polarographic behavior of the pesticide Diazinon was investigated in water/methanol solutions. Two methods are proposed for its determination. The first involves differential pulse polarography with a detection limit of 2.65 × 10-6 M, and the second is based on adsorptive stripping voltammetry at a hanging mercury drop electrode that yields a detection limit of 4.01 × 10-9 M.

    Notes: Thin films of TiNx with 0.34〈x〈1.19 were deposited on silicon substrates by a filtered arc deposition process. Spectroscopic ellipsometry (SE) in the energy region 1.5-3.5 eV was used to measure the optical properties of the films. X-ray photoelectron spectroscopy (XPS) was used to determine the relative atomic concentration and the chemical states of the elements. The dielectric function ε(ω) measured by ellipsometry gives the optical response of TiNx films and valuable information on their chemical composition, which is also verified by XPS. The plasma energy ωp of TiNx films was found to depend strongly on the N/Ti ratio and this is correlated with the value of x as determined by XPS and Rutherford backscattering spectroscopy (RBS). The results show that, via the calibration, spectroscopic ellipsometry may be used to estimate the stoichiometry of deposited TiNx films.

    Notes: Low energy ISS has been used to investigate, in situ, thin films of zirconium dioxide deposited by evaporation and ion-assisted deposition. It is shown that when a film is deposited to an average thickness of 0.3 nm ± 0.03, as measured by in situ ellipsometry, complete coverage of the substrate occurs. Ion-assisted films have detectably higher Zr surface concentrations and reduced low-energy sputter peaks. Inelastic tailing effects in the Zr scattering peak for 2 keV 4He+ are found to come from particles scattered from approximately the first 7 nm of the oxide surface. The influence of primary ion energy on the Zr/O ratio is also examined.
