    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: 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.

    Spontaneous breaking of global baryon number symmetry (1981)
    Springer
    The European physical journal 11 (1981), S. 175-178 
    Details
    ISSN: 1434-6052

    Topics: Physics
    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.

    Symmetry breaking in a supersymmetric model of strong and electroweak interactions (1982)
    Springer
    The European physical journal 13 (1982), S. 267-271 
    Details
    ISSN: 1434-6052
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    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.

    Description / Table of Contents: Crystsl and Molecular Structure of (C6H5)SnSAB (SAB = Dianion of 2-Hydroxy-N-(2-hydroxybenzylidene)-aniline)(C6H5),SnSAB, C25H19NO2Sn, (SAB = tridentate dianion of 2-hydroxy-N-(2-hydroxybenzylidene)-aniline in Schife base (form) crystallizes in the space group Peab (D2h15) with a = 11.095(2), b = 24.487(4), c = 14.993(3) Å and Z = 8. The structure has been solved using 1553 symmetrical independent reflections and applying the heavy atom method; the position of all atoms, except the H atoms has been determined. As interatomic distances have been found: Sn—C(C6H5):2.125, Sn—0: 2.085(8) resp. 2.103(8) Å; mean (C—C distances in the: phenyl groups a) at Sn: 1.400 b) in the ligand SAB: 1.397. The atoms N and especially C of the Schiff base bridging group C=N are disordered. The coordination polyhedron around Sn essentially forms a distorted trigonal bipyramidal structure with N and the C(C6H5) atoms bonded to Sn in the equatorial plane; CSnC = 121.4(4)°; OSnO = 159.5(3)°. No intermolecular Sn—0 bridges exist like in (CH3)2SnSAB.

Die Struktur wurde anhand von 1553 symmetrisch unabhängigen Reflexen nach der Schwerutommethode bestimmt und die Atomlagen bis auf die der H-Atome ermittelt. Für die interatomaren Abstände in der Molekel wurden gefunden: Sn—C(c6H5): 2.125, Sn—0: 2,085(8) bzw. 2,103(8) Å. Mittelwerte der C—C-Abstände in den Phenylringen a) an Sn: 1,400; b) im Liganden SAB: 1,397 Å. Für N und insbesondere für C im C=N-Brückenglied der Schiffschen Base liegt Fehlordnung vor. Das Koordinationationspolyeder um das Sn-Atom hat die Grundstruktur einer verzerrten trigonalen Bipyramide mit N und den Verknüpfungs-C-Atomen der Phenylgruppen in der Äquatorialebene; CSnC = 121,4(4)°; OSnO = 159,5(3)°. Im Gegensatz zu (CH3)2SnSAB liegen keine intermolekularen Sn—0. Brücken vor.

    Description / Table of Contents: Preparation, Crystal and Molecular Structure of Diphenyltin Glycylglycinate, (C6H5)2SnC4H6N2O3The title compound has been prepared from (C6H5)2SnO and Glycylglycine (H2GlyGly) in methanol. It crystallizes in the orthorhombic space group P212121 with a = 9.860(5), b = 11.787(8), c = 13.962(2) Å and Z = 4. The crystal structure has been determined from 1 109 independent reflections by Patterson and Fourier syntheses, and has been refined by least squares methods to R = 0.033. The (C6H5)2SnGlyGly molecules essentially form a heavily distorted trigonal bipyramid with peptide-N and the phenyl C-atoms bonded to Sn occupying the equatorial positions. The tridentate GlyGly ligand is practically planar coordinating through one carboxylate-O, peptide-N and amine-N. The single molecules are bridged by H-bonds between amine-N and carbonyl-O of the peptide-group and also carboxylate-O (not bonded to Sn). Important intramolecular bond distances and angles: see above.
    Notes: Die Titelverbindung wurde durch Umsetzung von (C6H5)2SnO mit Glycylglycin (H2GlyGly) in Methanol dargestellt. Sie kristallisiert orthorhombisch in der Raumgruppe P212121 mit a = 9,860(5), b = 11,787(8), c = 13,962(2) Å und Z = 4. Die Kristallstruktur wurde anhand von 1 109 unabhängigen Reflexen mittels Patterson- und Fourier-Synthesen bestimmt und nach der Kleinste-Quadrate-Methode bis zu einem R-Wert von 0,033 verfeinert. Die (C6H5)2SnGlyGly-Molekeln besitzen die Grundstruktur einer stark verzerrten trigonalen Bipyramide; Peptid-N und die beiden an Sn gebundenen Phenyl-C-Atome liegen äquatorial. Der dreizähnige GlyGly-Ligand ist praktisch planar und koordiniert über ein Carboxylat-O, sowie Peptid-N und Amin-N. Die Einzelmolekel sind über H-Brücken zwischen Amin-N und Carbonyl-O der Peptidgruppierung, sowie Carboxylat-O (nicht an Sn gebunden) verknüpft. Wichtige intramolekulare Abstände und Winkel: Sn—O: 2,157(8); Sn—N (Peptid): 2,082(8); Sn—N (Amin): 2,273(9); Sn—C: 2,113(9) (Mittelwert); C—N (Peptidgruppe): 1,330(13); C—N (Amin): 1,457(15) bzw. 1,499(14); C—Sn—C: 117,54(30); N—Sn—N 77,57(32); N(Peptid)—Sn—O: 75,71(31); C—Sn—N(Peptid): 121,1(3) (Mittelwert); C—N(Peptid)—C 119,47(91).

    Description / Table of Contents: Infrarot- und MÖSSBAUER-spektroskopische Untersuchungen an Komplexen von Hal2SnIV mit dreizähnigen LigandenNeue Komplexverbindungen von Typ hal2Sntrid werden dargestellt (hal = Cl, Br, und trid2- = ebene, dreizähnige Liganden mit ONO- und SNO-Atomen, als zweiwertige Anionen). In festem Zustand wurden die Strukturen durch IR- und MÖSSBAUER-Spektren untersucht. Mögliche Anordnungen der Liganden um das Zinn(IV)-Atom werden vorgeschlagen und diskutiert.Wahrscheinlich sind alle diese Verbindungen monomer mit einer trigonal-bipyramidalen Struktur; aber es können polymere oder dimere Anordnungen mit O- oder Cl-Brücken, besonders bei Br2Sntrid, nicht völlig ausgeschlossen werden.
    Notes: Novel complexes hal2Sntrid, where hal = Cl, Br, and trid2- are dianions of „planar“ tridentate ligands with ONO and SNO donor basic atoms, were synthesized and structurally investigated in the solid state mainly by far infrared and MÖSSBAUER spectroscopy. Possible configurations were advanced and discussed, and it was concluded that the most probable is a monomeric trigonal bipyramidal structure for all compounds, although polymers, or dimers with O or Cl bridges, were not a priori excluded, in a special way for Br2Sntrid.

    Description / Table of Contents: Organolead and Organotin Derivatives of Mercaptoaminoacids and CysteaminReaction of tri- and diorganolead and -tin hydroxides and oxides with mercaptoaminoacids and cysteamine in CHCl3 or CHCl3/H2O allows the gentle preparation of the above compounds. The bonding between M and ligand indicated in the formula of the compounds, mainly the preferred bonding of M to S follows from vibrational spectra; proposals regarding the structure are made using spectral data. Ph3SnOH and penicillamine react to give monomeric Ph3SnSCMe2CH(NH2)COOSnPh3.
    Notes: Die Umsetzung von Tri- und Diorganoblei-und -zinnhydroxiden bzw. -oxiden mit Mercaptoaminosäuren sowie mit Cysteamin in CHCl3 bzw.

Ph3SnOH reagiert mit Penicillamin zu monomerem Ph3SnSCMe2CH(NH2)COOSnPh3.
