Nucleotide sequences of the plastid genes psbB and psbC were obtained for 34 taxa to represent most genera currently classified within Vanilloideae (Orchidaceae). These genes code for two of the subunits that make up the Photosystem II protein P680, and have only rarely been used for reconstructing phylogenetic relationships among plants. We failed to amplify psbB from the achlorophyllous gener...

Integration of product design and operations could potentially enhance the ability of manufacturers to provide large variety in the product line while keeping their operations competitive. In this paper, we present an integrated model that provides insight on how manufacturers could design their products in order to delay diierentiation during operations. Our integrated model consists of two su...

The paper formally shows that the S-semantics is adequate for reasoning about the soundness and completeness of real Prolog metainterpreters, based on the non-ground representation of object-level variables. The paper extends some recent results by De Schreye and Martens, by proving the \equivalence" between the object program and its version metainterpreted by vanilla for any positive logic pr...
