    Antigenic relatedness of Proteus mirabilis and Escherichia coli with rat tissues and human erythrocytes (1980)
    Springer
    Antonie van Leeuwenhoek 46 (1980), S. 85-94 
    Details
    ISSN: 1572-9699
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The cross-reactions of rat kidney with P. mirabilis and E. coli, and of rat urinary bladder with P. mirabilis were established by precipitation, agglutination and immunofluorescence methods. One of the cross-reactive bacterial components was the lipopolysaccharide. Human erythrocytes of Blood-groups A, O and AB were agglutinated by antisera to P. mirabilis and E. coli. The role of antigenic relatedness in urinary tract infections is discussed.

    In vitro propagation of Valeriana jatamansi (1999)

    Plant cell, tissue and organ culture 59 (1999), S. 227-229

    Topics: Biology
    Notes: Abstract Valeriana jatamansi Jones is an important medicinal plant. This wild herb is being exploited for its roots and rhizomes which contain valepotriates, which are highly effective against leprosy. The aim of this study was to establish a practical method for rapid and large-scale multiplication of V. jatamansi by induction of shoot proliferation from shoot buds. The sterilized explants were established on solid medium supplemented with benzyl adenine alone or in combination with indole-acetic acid or naphthalene acetic acid. The buds cultured on nutrient medium supplemented with BA and IAA or NAA formed shoots, which after 3-4 weeks produced roots on the same medium. One hundred per cent survival was obtained on hardening and field establishment of well rooted shoots.

    An experimental investigation of mixed-mode fracture (1989)

    Description / Table of Contents: Résumé On étudie par voie expérimentale les ruptures selon un mode mixte. On explore, dans une première partie, les conditions d'amorçage de la croissance d'une fissure. En utilisant la méthode des caustiques en association avec un système vidéo à grande vitesse, on détermine les facteurs critiques d'intensité de contraintes correspondant à l'amorçage de la fissure. On trouve que le critère de contrainte maximum tangentielle, proposé à l'origine par Erdogan et Sih, est le meilleur en termes de capacité de prédiction. Pour les essais, on a utilisé du plyméthylméthacrylate et de l'Homalite-100, et on a trouvé que ce dernier matériau faisait état d'une sensibilité importante à la vitesse. La deuxième partie du travail est consacrée à la croissance d'une fissure sous un mode de sollicitations mixte. On montre que la propagation lente de la fissure dans le PMMA se produit sous des conditions de pur Mode I.
    Notes: Abstract In this paper, mixed-mode fracture is investigated experimentally. In the first part, critical conditions for initiation of crack growth are explored. The method of caustics was used in conjunction with a high speed video system to determine critical stress intensity factors at initiation of crack growth. It was found that the maximum tangential stress criterion originally proposed by Erdogan and Sih [1] was the best criterion in terms of predictive capability. Polymethylmethacrylate and Homalite-100 were used in the experiments and Homalite-100 was found to exhibit significant rate dependence. In the second part, crack growth initiated under mixed-mode loading is addressed. It is shown that subsequent slow crack growth in PMMA is under pure mode-I conditions.

    Description / Table of Contents: Zusammenfassung Der Einfluß von 5 verschiedenen Nematiziden, DBCP, D-D, Fensulfothion, Carbofuran and Aldicarb, wurde im Hinblick auf die chemische Zusammenzetzung von Tomatenfrüchten untersucht. Behandlung mit Nematiziden hatte eine beträchtliche Wirkung auf Trockensubstanz, Gesamtsäure, Ascorbinsäure, β-Carotin und Lycopin. Im allgemeinen nahm der β-Carotin-gehalt ab, während Säure- und Ascorbinsäuregehalt zunahmen. D-D und DBCP bewirkten eine Abnahme der Trockensubstanz, während alle anderen Behandlungen sie förderten. Der Lycopingehalt nahm bei allen Nematizid-Behandlungen ab, mit Ausnahme bei Aldicarb-Behandlung.
    Notes: Abstract The influence of five nematicides viz., DBCP, D-D, fensulfothion, carbofuran and aldicarb was investigated on the chemical composition of tomato fruits. Nematicidal treatment had considerable effect on the dry matter, acidity, ascorbic acid, beta-carotene and lycopene content. In general, beta-carotene content decreased whereas acidity and ascorbic acid content increased. D-D and DBCP decreased the dry matter while all other treatments increased it. Lycopene content decreased with all nematicides except aldicarb.

    Notes: Abstract Five nematicides — aldicarb, carbofuran, phorate, fensulfothion and DBCP — were studied in a field experiment to investigate their effect on the chemical composition of the fruits of egg-plant. There were no significant differences in the dry matter content of fruits from different treatments. A significant decrease in the crude protein content was observed with nematicide treatments. Phenolic compounds increased on application of phorate while all other treatments, except carbofuran, decreased these compounds. A significant increase over control in solasodine content of fruits was observed with all treatments.

    Experimental determination of stress-intensity factors using caustics and photoelasticity (1989)
    Springer
    Experimental mechanics 29 (1989), S. 6-11

    Notes: Abstract The optical method of caustics has been used with considerable success in recent years for determining stress-intensity factors in both static and dynamic problems. However the midplane analysis explaining the formation of transmission caustics has certain approximations that need to be examined. In this paper it is demonstrated that the midplane analysis is in good agreement with the numerical solution of the exact geometrical optical equations for mapping the light-ray path in a cracked plate. Since both these analyses are obtained by imposing a two-dimensional crack-tip stress field the sensitivity of the method to the deviations from the imposed stress field is examined next. The implications of this examination on the photoelastic technique are then discussed.

    Description / Table of Contents: Darstellung und IR-Untersuchungen der Komplexe von Methylethyl-, Ethyl(n-Propyl)-und n-Propyl (n-Butyl)zinn-dichloriden mit einigen StickstoffdonatorenEs wurden die Komplexe von Methylethylzinn-dichlorid mit 3-, 4-Picolinen, Isoquinolin und Benzylamin, von Ethyl(n-propyl)zinn-dichlorid mit Pyridin, 3-Picolin und Isoquinolin and von n-Propyl(n-butyl)zinn-dichlorid mit Isoquinolin, n-Propylamin and Benzylamin dargestellt und ihre Zusammensetzung aus dem Zinn- und Chlorgehalt bestimmt. IR-Messungen (4000-200 cm-1) weisen darauf hin, daß in allen hexakoordinierten Komplexen des Methylethyl-zinn-dichlorides die Chloratome in eis-Position stehen. Im Fall der hexakoordinierten Komplexe des Ethyl(n-propyl) und n-Propyl(n-butyl)zinn-dichlorides jedoch kann die mehrfache Aufspaltung der Zinn-Chlorvalenzbande auf dem Vorliegen von Konformationsisomeren beruhen. Leitfähigkeitsmessungen wurden zur Bestimmung des Ionencharakters ausgeführt.
    Notes: Complexes of methylethyltin dichloride with 3-, 4-picolines, isoquinoline and benzyl amine, of ethyl(n-propyl) tin dichloride with pyridine, 3-picoline and isoquinoline and of n-propyl (n-butyl)tin dichloride with isoquinoline, n-propyl amine and benzyl amine have been prepared and their stoichiometries established from their tin and chlorine contents. I.R. measurements (4000-200 cm-1) suggest that in all the hexa-coordinated complexes of methylethyltin dichloride, the chlorines are in cis-position. In case of hexa-coordinated complexes of ethyl(n-propyl)- and n-propyl (n-butyl) tin dichlorides, however, the multiple splitting of tin-chlorine stretching band may also be due to the presence of conformational isomers. The conductance measurements have also been carried out to determine their ionic character.
