    Preparation and detection of alignment with high ||m|| selectivity by saturated laser optical pumping in molecular beams (1986)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 85 (1986), S. 286-302

    Notizen: We describe a technique for preparation of molecules in single ||m|| levels involving saturated laser optical pumping on molecular P, R, and Q transitions. This technique is not limited to small rotational quantum numbers j. It allows the determination of the populations of ||m|| levels for arbitrary distribution functions f ( j,m) or alternatively, the determination of all moments of f ( j,m). In principle, this method is able to completely determine the angular distribution of j vectors. Experimental verification of the high ||m||-state purity achieved in Na2 supersonic beams, as well as of inherent limitations due to hyperfine interaction is provided. For illustration, experimental data on laser-induced alignment, the dependence of the flow induced molecular alignment, and on Δm-propensity rules in differential rotationally inelastic scattering are presented.

    Angularly resolved rotational energy transfer in highly vibrationally excited states: Na2(v=31)–Ne (1991)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 94 (1991), S. 4252-4259

    Notizen: The scattering of high vibrationally excited sodium molecules Na2(v=31) with Ne atoms at 180 meV collision energy is investigated in a crossed molecular beam arrangement using laser optical methods. Angularly resolved rotationally inelastic and vibrationally elastic cross sections ji→jf are measured for ji =5, 7, and 9≤jf ≤25. Pronounced rotational rainbow maxima are observed, the angular position of which indicates a significantly larger anisotropy of the interaction potential compared to that of Na2(v=0)–Ne. Except for the increase of the anisotropy the vibrational excitation has little effect on the dynamics of rotational energy transfer. Good agreement with a new semiempirical Na2–Ne potential surface V(r,R,γ) is found.

    Fibroblastic rheumatism: clinical, histological, immunohistological, ultrastructural and biochemical study of a case (1993)

    Thema: Medizin
    Notizen: We report a case of fibroblastic rheumatism (FR). Only eight other cases of this recently described entity have been reported previously. FR is characterized hy polyarthralgia and joint stiffness without joint destruction, associated with cutaneous nodules and sclerodactyly. Histology shows an increase in the number of fihroblasts and marked dermal fibrosis, Rheumatological and skin manifestations may improve with corticosteroid therapy.In our patient, immunohistochemical studies of involved and uninvolved skin showed an increase in fibronectin and tenascin deposition. In the dermis, the hyperplastic cells had phenotypic features of muscle, suggesting myofihrohlastic differentiation. Ultrastructural study showed an increase in active fibroblastic cells with features of myofibroblasts. A hyperproliferative capacity was observed in fibroblasts cultured from involved skin. Biochemical studies of the production of collagen and non-collagen proteins were performed on these cultured cells, and showed a reduction in collagen and non-collagen protein synthesis hy FR fihrohlasts. Thus, FR appears to differ from other fibrotic skin diseases such as scleroderma, in that dermal fihrosis may be due predominantly to fibroblast proliferation with myofihrohlastic differentiation, without any increase in collagen synthesis.

    Effect of Liquid Smoke on the Growth of Lactic Acid Starter Cultures used to Manufacture Fermented Sausage (1982)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 47 (1982), S. 0 
    Details
    ISSN: 1750-3841

    Notizen: Fermented sausage was manufactured using a commercial lactic acid starter culture and varying levels of liquid smoke. Samples were taken during the 24 hr fermentation period and the lactic bacterial count, pH and titratable acidity determined. Final pH values, titratable acidity and lactic bacterial counts were not affected by recommended use levels of liquid smoke, although exponential growth was delayed. Growth studies in a broth medium containing liquid smoke suggest that liquid smoke has the potential for inhibiting the lactic starter cultures used to make fermented sausage.

    A Direct Hexane Extraction Process for Glanded Cottonseed (1982)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 47 (1982), S. 0 
    Details
    ISSN: 1750-3841
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft , Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: A modified filter funnel apparatus was used to determine mass flow velocities for extraction of uncooked glanded cottonseed flakes, and the results were compared with a continuous pilot-plant-scale extractor. A mass velocity of 2,000 lb/hr/ft2 or higher (considered adequate for oilseed extraction) was obtained in all cases. Both the initial meat moisture before flaking and the flake moisture during extraction were found to affect the mass velocity. A meat moisture before flaking of less than 9% decreased the mass velocity, probably as a result of increased fines and thus smaller flake size. A high flake moisture (about 9%) during heated-hexane extraction caused a decrease in mass velocity compared to that of lower-moisture flakes. The correlation of filter-funnel mass velocity data to a continuous pilot-plant extractor confirmed that uncooked flakes can be satisfactorily extracted to yield low residual lipids by using a low solvent-to-flake ratio and ambient-temperature hexane solvent.

    Investigations on the Anther Culturability of Four German Spring Wheat Cultivars and the Influence of Light on Regeneration of Green vs. Albino Plants (1990)
    Oxford, UK : Blackwell Publishing Ltd
    Plant breeding 105 (1990), S. 0 
    Details
    ISSN: 1439-0523
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft
    Notizen: In anther culture experiments with four German spring wheat cultivars (‘Turbo’, ‘Kadett’, ‘Planet’ and ‘Nandu’), ‘Nandu’ showed the best results. The rate of responding anthers with ‘Nandu’ was 0.8 % on medium N6 and 3.7% on potato-2. This was similar to the Chinese cultivar ‘Orofen’. Higher yields of embryoids could be obtained with medium potato-2 than with N6.Experiments with medium potato-2 showed that anther response, production of embryos and regeneration increased with decreasing agarose concentration.Regeneration of green plantlets was improved by differentiation in the dark whereas differentiation under light yielded more than 90 % albino plants.

    HEAT-INDUCED TRANSITIONS IN THE PROTEIN-PROTEIN INTERACTION OF BOVINE NATURAL ACTOMYOSIN (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food biochemistry 8 (1984), S. 0 
    Details
    ISSN: 1745-4514
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: Protein-protein interaction of bovine natural actomyosin (NAM) was studied by means of optical density changes resulting from discrete particle formation in the temperature range of4°C to 70°C. From Arrhenius plots, the apparent heat of activation (ΔHa) at pH 5.5 (17.1 kcallmole) was significantly (P〈0.05) lower than activation energies in the pH range of 6.0 to 7.5. The lower Δ Ha resulted in initiation of protein-protein interaction at a temperature near 16°C at pH 5.5, whereas interaction did not proceed until the temperature approached 37°C at pH 6.0 and above. Derivative curves (dOD/dT) at pH 5.5 and 6.0 showed two distinct NAM thermal transition regions. Tm1 occurred at 43.0°C at pH 5.5 and 48.5°C at pH 6.0, with the 5.5°C difference possibly arising from effects of proton binding in altering protein conformation. Only a 1.5°C difference in Tm2 (56.0°C at pH 5.5 versus 57.5°C at pH 6.0) was found. Although the overall heat-mediated NAM aggregation (in dilute solution) was found to follow first order kinetics by two evaluation methods, the existence of two thermal transitions supports a two-step reaction mechanism proposed for the formation of protein gels (in higher concentration solutions).
