In the framework of orbifold compactifications of heterotic and type II orientifolds, we study effective N = 1 supergravity potentials arising from fluxes and gaugino condensates. These string solutions display a broad phenomenology which we analyze using the method of N = 4 supergravity gaugings. We give examples in type II and heterotic compactifications of combined fluxes and condensates lea...

SQL:2003, die neuste Version der SQL-Norm, sieht erstmals die Unterstützung von XMLDaten vor. Damit wird es möglich, Tabellen mit XML-wertigen Spalten anzulegen. Der vorliegende Beitrag geht der Frage nach, welche prinzipiellen Möglichkeiten es für die Übergabe von XML-Werten zwischen Datenbanksystem und Anwendungsprogrammen gibt. Da die Eignung dieser Möglichkeiten von den Charakteristika der ...

The purpose of this paper is to investigate acoustic characteristics which distinguish ejectives from pulmonic stops in Ingush (a Northeast Caucasian language), and to compare Ingush ejectives to those of other languages. The articulation of ejectives is relatively well understood, but their acoustic effects are less clear. Working with a native speaker of Ingush, ejectives and pulmonic voicele...

The available type material of Phlebotominae (Diptera, Psychodidae) deposited in the "Coleção de Flebotomíneos" of the Instituto Evandro Chagas (ColFleb IEC) is now presented in an annotated catalogue comprising a total of 121 type specimens belonging to 12 species as follow: Nyssomyia richardwardi (2 female paratypes), Nyssomyia shawi (9 male and 25 female paratypes), Nyssomyia umbratilis (fem...
