    Notes: During the recent years, due to the rapid development in Finite Element modeling, as well as the rapid evolution of computer techniques, numerical modeling has become an important everyday tool not only for process analysis and process optimization but for die design and rapid die manufacturing, as well. The Department of Mechanical Technology at the University of Miskolc is regarded as the leading research centre for Computer Aided Engineering of sheet metal forming processes in Hungary. The activity of the department covers the computer aided technological and tool design, the development and application of knowledge based expert systems for process planning and process optimization and die design using sophisticated FEM packages. In this latter activity, the AutoForm Engineering GmbH is a strategic partner of the department for several years. In this paper, the concept for an integrated computer aided die design system specialized for the rapid design of parametric die faces using finite element simulation technique will be presented

    Notes: Summary A new method has been developed for qualitative and quantitative analysis of fumonisin FB1 and FB2 in corn and corn products. After extractive sample preparation followed by solid phase extraction using a strong anionexchanger, highest selectivity and sensitivity was achieved by high-performance liquid chromatography-electrospray-ionization, tandem mass spectrometry (HPLC-ESI-MS-MS) analysis combined with selected reaction monitoring (SRM). With deuterated fumonisin FB1-d6 as internal standard the routine quantitation limit for FB1 was set at 400 pg (0.8 ng g−1 sample) with a signal-to-noise ratio of 10∶1. Almost all corn grit and corn meal samples under study were found to be contaminated with fumonisin FB1 and FB2 in concentrations ranging from 1 to 200 ng g−1. Lower fumonisin levels were found in cornflakes, popcorn and baby food, while no fumonisins were detected in canned sweet corn.

    Description / Table of Contents: Einfluß der Temperatur auf das elektrochemische Korrosionsverhalten von TitanDer Einfluß der Temperatur auf die elektrochemischen Korrosionseigenschaften des handelsüblichen VT 1-0 Titans wurde in 1 mol/dm3 Schwefelsäure-Lösungen im Temperaturbereich 293-353 K untersucht. Die elektrochemischen Messungen wurden mittels galvanostatischer und quasi-potentiostatischer Polarisationsmethoden durchgeführt. Die Korrosionsgeschwindigkeiten wurden auch aufgrund des Massenverlustes bestimmt. Die Steilheit der aus den galvanostatischen Polarisationsmessungen erhaltenen kathodischen Tafel-Geraden ändert sich anomalerweise mit der Temperatur. Aus den Massenverlustdaten berechnete Korrosionsgeschwindigkeiten haben eine größere Temperaturabhängigkeit als diejenigen, die mit der Polarisationsmethode bestimmt wurden, aus auf eine Selbstauflösung hinweist.Die Ergebnisse wurden der Anwesenheit einer Hydridschicht zugeschrieben. In dieser Schicht nimmt das Wasserstoff/Titan-Verhältnis mit der steigenden Temperatur zu. Das Titanhydrid spielt eine entscheidende Rolle sowohl in der Wasserstoffentwicklung als auch in der Selbstauflösung.
    Notes: The influence of variations in temperature on the electrochemical corrosion properties of VT 1-0 commercial titanium was studied in deaerated 1 mol/dm3 sulphuric acid between 293 and 353 K. Galvanostatic and quasi-potentiostatic polarization measurements were carried out. Corrosion rates were determined by mass loss measurements, too. The slopes of the cathodic Tafel-like lines obtained with galvanostatic polarization change anomalously with temperature. The corrosion rates calculated from the mass loss data increase with increasing temperature at a higher rate than those determined with the polarization method, pointing to a self-dissolution process. The results are attributed to a hydride layer with a H/Ti ratio increasing with temperature. Titanium hydride may play a dominant role both in the hydrogen evolution reaction and in the self-dissolution process.
