    Quantitative trait loci mapping in plant genetics by alpha-design experiments and molecular genetic marker systems

    Get PDF
    Research concerning the quantitative trait loci (QTL) mapping in plant genetics usually consists of two stages. The first stage is concerned with collecting data while the second one, based on the data collected, is concerned with a proper QTL study. The final inferences are strictly connected with the quality of the two approaches applied in both stages. Data to be analyzed come from an experiment dealing with offsprings obtained from a crossing system of several lines. The genotypes then are observed in some natural or quasi natural environment. The QTL studies are based on so called genotype adjusted means. In a-designs the adjusted means can be calculated in many ways, which will be presented in this paper. We also give an EM-algorithm for the estimation of genetic parameters and comment on recent biometrical research in molecular plant genetics. Finally we mention some activities in the new field of bioinformatics

    Penrose-Pflasterungen in der Architektur - die künstlerische Umsetzung eines mathematischen Modells im Gemeindeverwaltungs-Zentrum von Bütgenbach, Belgien

    Der englische Physiker und Mathematiker Roger Penrose hat eine mathematische Pflasterung entdeckt, deren Formenreichtum neue Impulse in der Architektur setzen kann. In der Gemeinde Bütgenbach im Hohen Venn, Belgien, wurde das Verwaltungszentrum durch den Essener Architekten Ernst Burghartz mit mehrereren Penrose-Pflasterungen versehen. Diese beruhen auf einem Computer-Programm, welches der Vortragende zusammen mit Dr. Frank Martini entwickelt hat. Herr Burghartz hat jedoch diesen Vorentwurf nach seinen künstlerischen Vorstellungen abgewandelt
