    Notes: Summary A heterogeneous distribution of H+-ATPase was visualized in germinated pollen ofLilium longiflorum using monoclonal antibodies raised against plasma membrane H+-ATPase. Immunolocalization studies of protoplasts and subprotoplasts derived from pollen tubes and sectioned pollen grains and pollen tubes show that H+-ATPases are abundant in the plasma membrane of pollen grains but are absent or sparsely distributed in the plasma membrane of pollen tubes. This polar distribution of H+-ATPases is probably the basis of the endogenous current pattern measured in growing lily pollen and involved in pollen tube tip growth.

    Description / Table of Contents: Crystal and Molecular Structures of (Me2SiNCN)4 (1) and Me3SiNCNSiMe3 (2)Synthesis, spectroscopic characterization (NMR, IR, Raman and MS) and crystal structure of the novel compound 1 are described. The molecules form almost planar 16 membered rings with four SiMe2-groups connected to four NCN groups. The corresponding compound 2 exhibits a phase transition from the HT phase 2a to the LT phase 2b at 131 K. Consecutive X-ray structure determinations of the molecular structures of both modifications were performed on a crystal, grown in situ on the diffractometer at 231 K.
    Notes: Für die neuartige Verbindung 1 werden Synthese, spektroskopische Charakterisierung (NMR, IR, Raman und MS) und die Kristallstruktur beschrieben. Das Molekül besteht aus einem nahezu planaren 16gliedrigen Ring, in dem vier SiMe2-Gruppen mit vier NCN-Gruppen verknüpft sind. Die Vergleichsverbindung 2 zeigt eine Phasenumwandlung von der HT-Phase 2a in die TT-Phase 2b bei 131 K. Die Molekülstrukturen beider Modifikationen wurden nacheinander durch Röntgenstrukturanalyse an einem in situ bei 231 K auf dem Diffraktometer gezüchteten Kristall bestimmt.

    Description: This paper describes a set of C++ extensions to the CLIPS language and their embodiment in CLIPS++. These extensions and the implementation approach of CLIPS++ provide a new level of embeddability with C and C++. These extensions are a C++ include statement and a defcontainer construct; (include (c++-header-file.h)) and (defcontainer (c++-type)). The include construct allows C++ functions to be embedded in both the LHS and RHS of CLIPS rules. The header file in an include construct is the same header file the programmer uses for his/her own C++ code, independent of CLIPS. The defcontainer construct allows the inference engine to treat C++ class instances as CLIPS deftemplate facts. Consequently existing C++ class libraries may be transparently imported into CLIPS. These C++ types may use advanced features like inheritance, virtual functions, and templates. The implementation has been tested with several class libraries, including Rogue Wave Software's Tools.h++, GNU's libg++, and USL's C++ Standard Components. The execution speed of CLIPS++ has been determined to be 5 to 700 times the execution speed of CLIPS 6.0 (10 to 20X typical).
