Conopharyngine, the major alkaloid present in the leaves of Tabernaemontana (Conopharyngia) pachysiphon var. cumminsi (Stapf) H. Huber was isolated and identified by Thomas & Starmer (1963). The same alkaloid has also been found in the stem bark of a Nigerian variety of the same species by Patel & Poisson (1966) and in the stem bark of Conopharyngia durissima by Renner, Prins & Stoll (1959). Co...
INTRODUCTION Surface tension is an inherently dominant force in the microscale. Electrocapillarity, the modification of surface tension by applying an electric field, has received renewed attention because of its potential usefulness in microfluidics. Pollack et al. demonstrated a microactuator for rapid manipulation of discrete microdroplets by direct electric control of the surface tension. [...
Roundtable discussion: how lessons learned from HIV can inform the global response to viral hepatitis Jeffrey V Lazarus, Jens Lundgren, Jordi Casabona, Lucas Wiessing, Catharina Matheï, Peter Vickerman , Maria Prins , Mirjam Kretzschmar , Maria Kantzanou, Isabelle Giraudon, Marica Ferri, Paul Griffiths, Magdalena Harris, Margaret Walker, Lilyana Chavdarova, Eberhard Schatz, Katrin Schiffer, Joh...
Theophylline, a methylxanthine compound, is known as an efficient bronchodilatator drug, having also anti-inflammatory and immunomodulatory effects. In order to improve its pharmacological profile and to reduce also the serious side effects that appear at high concentrations, new theophylline derivatives have been synthesized. The new compounds are obtained in two steps by the reaction of 8-sub...
Releele non-transparente IEEE802.16j „multi-hop” constitue o soluţie promiţătoare pentru extinderea cu preţ scăzut a acoperirii şi capacităţii reţelelor WiMAX. Apar însă anumite probleme, cum ar fi alegerea unei căi de la staţia de bază prin releele disponibile, determinând în final o topologie tip arbore, sau alegerea unei căi cu interferenţă minimă. Aceasta lucrare urmăreşte evaluarea perform...
An approach to 2,4,5-trisubstituted piperidines is reported, in which the key step is the Prins or carbonyl ene cyclisation of aldehydes of the type 1. Prins cyclisation catalysed by concentrated hydrochloric acid in CH(2)Cl(2) at -78 degrees C afforded good yields of two of the four possible diastereomeric piperidines, with the 4,5-cis product 7 predominating in a diastereomeric ratio of up to...

We substantially re ne the theory of singular prin ipal bundles introdu ed in a former paper. In parti ular, we show that we need only honest singular prin ipal bundles in our ompa ti ation. These are obje ts whi h arry the stru ture of a rational prin ipal bundle in the sense of Ramanathan. Moreover, we arrive at a mu h simpler semistability ondition. In the ase of a semisimple group, this is ...
Enecarbamates are shown to be excellent terminating groups for Prins cyclizations. A noteworthy feature of this methodology is the easy, stereoselective construction of the cyclization precursors by alkylation of metalated (E)-enecarbamates with epoxides. The stereochemistry of the resultant trisubstituted (E)-enecarbamates is then transferred with high fidelity to afford the frequently observe...
The new genus Macrosaccus Davis & De Prins is proposed for three species formerly assigned to the genus Phyllonorycter: Macrosaccus robiniella (Clemens), Macrosaccus morrisella (Fitch), and Macrosaccus uhlerella (Fitch); two new, closely related species: Macrosaccus neomexicanus Davis and Macrosaccus gliricidius Davis, are also proposed. Descriptions of the adults, pupae, larvae, life histories...
