My special thanks go to my supervisor Prof. Wendel. He did not only provide excellent working facilities and a generous financing of the project, but also enabled this study by his patience, his encouragement and his stimulating ideas. Moreover, he exemplified impressively the successful fusion of science and other aspects of life. (Altana Pharma Konstanz) enabled me to attend conferences, trai...
We present a specialized branch-and-bound (b&b) algorithm for the Euclidean Steiner tree problem (ESTP) in R and apply it to a convex mixed-integer nonlinear programming (MINLP) formulation of the problem, presented by Fampa and Maculan. The algorithm contains procedures to avoid difficulties observed when applying a b&b algorithm for general MINLP problems to solve the ESTP. Our main emphasis ...

In this laboratory a study of the oxygen capacities of chemically modified hemoglobins has recently been undertaken. In connection with this work the reduction of methemoglobin under carefully controlled conditions offered itself as a problem, since the combination of a ferriheme with globin leads to methemoglobin. In view of this consideration and of the recent reports of Cox and Wendel (l), M...
Phylogenetic reconstruction in the Poaceae began early in this century with proposed evolutionary hypotheses based on assessment of existing knowledge of grasses (e.g., Bew, 1929; Hubbard 1948; Prat, 1960; Stebbins, 1956, 1982; Clayton, 1981; Tsvelev, 1983). Imperical approaches to phylogenetic reconstruction of the Poaceae followed those initial hypotheses, starting with cladistic analyses of ...
Analytical Ultracentrifugation (AUC) is a fractionating technique based on the synchronized optical detection of the concentration profiles of the sample under a centrifugal acceleration of up to 300,000 g. The skilled choice of solvent, rotational speed and detection optics enables a variety of complementary AUC experiments due to the controlled interplay of centrifugal force, hydrodynamic fri...
Edi tor ’s Note : NEHA strives to provide up-to-date and relevant information on environmental health and to build partnerships in the profession. In pursuit of these goals, we feature a column from the Environmental Health Services Branch (EHSB) of the Centers for Disease Control and Prevention (CDC) in every issue of the Journal. In this column, EHSB and guest authors from across CDC will hig...
Franz Leberl Philipp Meixner Andreas Wendel Arnold Irschara Graz University of Technology Institute for Computer Graphics and Vision Inffeldgasse 16 A-8010 Graz, Austria E-mail: [email protected] Abstract. The location-aware Internet is inspiring intensive work addressing the automated assembly of three-dimensional models of urban spaces with their buildings, circulation spaces, vegetation, ...
In Benin as in the African sub-region, burden of Non-Communicable Diseases (NCDs) and threats they represent constitute a major public health problem which hinders their economic social development. NCDs kill 36 million people each year 80% deaths occur developing countries, including Benin. The objective our work is to evaluate acute, subacute toxicity anti-hyperglycemic activity five plants l...
Mancozeb is sprayed on bananas to prevent black sigatoka, a fungal disease that impairs fruit ripening and reduces banana yields. In this issue of EHP, investigators report that pregnant women living near banana plantations in Costa Rica have elevated urinary levels of ethyl ene thiourea (ETU), a metabolite of mancozeb. At 2.9 μg/L, the median ETU level in these women was nearly twice the 95th ...
