    Notes: An expanded nutrient snack was prepared by extrusion cooking of defatted corngerm flour added with increasing amounts of milk proteins. Two extrusion temperatures (150 and 170°C) were considered. Physical, chemical and nutritional characteristics of the final product were evaluated. The products extruded at 150°C showed better expansion and crispness than the ones obtained at 170°C. A small addition of milk protein (5%) improves the organoleptic characteristics of the extrudates produced at 150°C. On the contrary the addition of milk protein has a negative influence on the product expansion and consistency of the samples extruded at 170°C.

    Notes: Macaroni was produced from commercial durum semolina blended with 10, 20, and 30% defatted corn germ meal. The effect of germ supplementation on chemical composition, physical properties of dough, cooking characteristics, mechanical properties, and panel acceptability of macaroni were studied. Addition of corn germ meal resulted in longer mixing time of the dough, higher farinograph water absorption, higher protein content of the products and improvement of amino acids pattern. Optimum cooking time and percent increase in weight of cooked macaroni decreased with increasing levels of wheat substitution. Enrichment with germ flour had no effect on flavor and texture of conventional macaroni evaluated by taste panels; it greatly affected physical measurements of cooked product texture causing an increase of firmness.

    Notes: A defatted corn germ flour of good organoleptic and nutritional quality was obtained by applying a milling and screening process to a commercial defatted corn germ meal. The flour contains about 20% protein of good nutritional quality, above 60% starch and minor quantities of fat (1.7%), fibre (3.3%) and minerals (8.42%). The last are interesting for their content in potassium, magnesium, iron and zinc. Heat effects on protein were evaluated in the intermediate and final products of a commercial oil extraction installation. It was found that the conditioning step sharply decreased protein solubility, while protein digestibility remained substantially constant throughout the process.

    Notes: Abstract We describe a supersymmetric model of strong and electroweak interactions based on the gauge groupSU(3)×SU(2)×U(1)×Ũ(1). We concentrate on the pattern of the spontaneous symmetry breaking by the tree level scalar potential. It is possible to break theŨ(1) factor at superlarge energies relative to the simultaneous breaking scale ofSU(2)×U(1) and supersymmetry. The model hasŨ(1) anomalies. Attempts to make an anomaly-free model based on the groupE 6 are described. We also comment on possible modifications of theŨ(1) anomaly problem due to gravitational effects.

    Notes: Abstract We study the possibility that theU(1) B global symmetry associated with baryon number is spontaneously broken. We present realistic examples implemented in the context of a suitably extended standardSU(2) L×U(1)×SU(3)c model and of a composite model of quarks and leptons. The globalU(1) B symmetry in both cases is spontaneously broken at a relatively low mass scale without any conflict with observations. The dominant baryon number nonconserving process in these models obeys the ΔB=2 selection rule.

    Notes: Abstract We compute the one loop quadratic divergences to the effective potential of the matter scalars inN=1 supergravity. We discuss in some special instances (the Das-Freedman and the Deser-Zumino Lagrangians) the problem of supersymmetry gauge invariance. We comment on the relevance of the calculation to model building.

    Description / Table of Contents: Sommario Viene descritto un terreno chimicamente definito che facilita la sopravvivenza di neuroni di cervello di feto di ratto in coltura primaria. Più del 90% delle cellule in coltura vengono identificate come neuroni mediante immunofluorescenza con anticorpi antineurofilamenti. Il terreno, arricchito con siero, invece, stimolando la proliferazione delle cellule nonneuronali, ostacola la sopravvivenza dei neuroni.
    Notes: Abstract A Chemically Defined Medium is described which facilitates the survival of neurons in primary cultures of rat cerebral hemispheres. More than 90% of all cells were identified as neurons using neurofilament as a marker in an immunocytochemical assay. In contrast, serumsupplemented medium, by stimulating nonneuronal cell proliferation, hinders the survival of neurons in culture.

    Description / Table of Contents: Complexes R2SnL (R = CH3, C6H5; L2- = tridentate ONO and SNO ligands) are synthesized, and their configuration is investigated by vibrational, PMR and electronic spectroscopy.The ligands H2L are: 2-pentanone-4-(2-benzothiazolinyl), (prepared for the first time); 3-(o-hydroxyphenylamino)crotonophenone; 2-(o-hydroxyphenyl)benzothiazoline; 2,2′methylidynenitrilo diphenol. Their configuration at the solid state is discussed. The ligands seem to coordinate the tin (IV) atoms as planar tridentates, in the dianion Schiff base form.The R2SnIV moieties very probably assume a bent configuration in R2SnL. Hypotheses on the structure of R2SnL are then advanced: the possible occurrence of a quasi trigonal bipyramidal geometry, where the two carbon (R) atoms and the azomethine nitrogen atom are allocated in the trigonal plane and the O, O or S, O ligand atoms lie in axial position, is discussed.
    Notes: Komplexverbindungen vom Typ R2SnL (R = CH3, C6H5; L ist ein dreizähniger ONO- oder SNO-Ligand) werden dargestellt und ihre IR-, KMR- und elektronischen Spektren untersucht, um die Strukturen zu klären.Als Liganden (LH2) werden benutzt: 4-(2-Benzothiazolinyl)-pentan-2-on, (hier zum ersten Mal dargestellt); 3-(o-Hydroxyphenylamino)crotonophenon; 2-(o-Hydroxyphenyl)-benzothiazolin; und N-o-Hydroxybenzyliden-o′-hydroxyanilin.Im festem Zustand umgeben die organischen Liganden L2- das Zinn(IV)-Atom als ebene dreizähnige Liganden. Die R2SnIV-Reste sind wahrscheinlich nicht linear. Eine mögliche Anordnung der Liganden ist eine trigonale Bipyramide, in der die zwei R-Reste und das Stickstoffatom in der trigonalen Ebene und die zwei Sauerstoffatome bzw. das Sauerstoff- und das Schwefelatom in den zwei anderen Positionen auf beiden Seiten der Ebene liegen.

    Description / Table of Contents: Komplexe des Zinn (IV) mit dreizähigen Liganden. Mössbauer- und IR-Spektren sowie Untersuchungen von LösungenDie Struktur von SnIV-Komplexen mit dreizähnigen “planaren” Liganden, Sn(trid)2 und HNEt3Cl2Sntrid, wurde in fester Phase und in Lösung untersucht mit Hilfe von IR- und MÖSSBAUER-Spektroskopie (für den festen Zustand) sowie osmometrisch, mit Leitfähigkeitsmessungen, UV-VIS- und NMR-Spektroskopie. Danach wird das Vorliegen von monomerem Sn(trid)2 und ionischem [HKEt3]+[Cl3Sntrid]- angenommen. Bei beiden Arten von Verbindungen liegt vermutlich oktaedrische Konfiguration vor.
    Notes: The configuration in the solid state and in solution phase of complexes of SuIV wit,li tridentate “planar” ligands, Sn(trid)2 and HNEt3Cl3 Sntrid, have been investigated by infrared and MÖSSBAUER spectroscopy, as well as by osmometry, conductivity, and electronic and PMR spectroscopy. The presence of monomeric Sn(trid)2 and ionic [HNEt+3] [Cl3Sn trid-] species has been inferred. Octahedral type configurations are advanced for both classes of compounds.

    Notes: New complexes R2PbL, where L2- are the dianions in the “planar” SCHIFF base form, of the tetradentate ONNO ligands α, α′ (ethylenedinitrilo)dicresol and 2,2′ bis-benzoxazoline, were synthesized. Their configuration was investigated at the solid state by infrared spectroscopy, and in solution phase mainly by electronic and PMR spectroscopy. An octahedral type structure with linear CPbC moieties, and the ONNO ligand atoms chelating PbIV in a square plane, was advanced.
