    Saccharification of bamboo carbohydrates for the production of ethanol (1983)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 25 (1983), S. 1071-1082

    Notes: Bamboo carbohydrates were hydrolyzed with commercial amylases and a mixture of fungal culture broths containing cellulolytic and hemicellulolytic enzymes. The effects of cooking temperature and the size of fiber particles were also investigated. It was found that the higher the cooking temperature, the higher the rate of sugar formation and the lower the viscosity of the slurry. Additions of cellulose and hemicellulose digesting enzymes increased the sugar yield and decreased the viscosity of both the cooked and noncooked slurries. A smaller size of particle appeared to favor the average saccharification rate. Although glucose, xylose, and cellobiose were present in the hydrolysates, only 50% of the total carbohydrate was digested, and 78.9% of this was converted to reducing sugars. The alcohol efficiency for the fermentation of cooked and noncooked mashes by Saccharomyces was about 85%.

    Mobilization of oil ganglia (1983)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 29 (1983), S. 854-858 
    Details
    ISSN: 0001-1541

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Following secondary recovery processes in conventional light oil reservoirs, more than half the original oil in place may remain trapped as a discontinuous phase. During the previous recovery processes these oil ganglia have been pinched off by capillary forces and remain immobile while the continuous phase which surrounds them is able to flow freely. Furthermore if a portion of this oil is mobilized in a tertiary recovery process the conditions required to apply Darcy's equation to the flow of either phase are violated. These are also problems which are encountered during in-situ recovery techniques in tar sands where the mobilization of the heavy oil occurs as a discontinuous phase. In this paper the relevant flow equations are derived. Also a parameter is deduced which directly determines the criterion for mobilization.

    Notes: Experimental results of the formation of methane hydrate in dependence of temperature and pressure in unsaturated solutions of NaCl in water will be presented in a temperature range from 261.85 to 285.98 K and pressure up to 11.0 MPa. Furthermore the four-phase equilibrium NaCl·2H2Os— CH4·nH2Os—L—G has been calculated from the experimental results. Also the heats of transformation of several other equilibria in the ternary system CH4—H2O—NaCl are obtained.

    Structure-properties relationships in biaxially oriented polypropylene films (1983)
    Stamford, Conn. [u.a.] : Wiley-Blackwell

    Notes: A series of biaxially oriented polypropylene films has been extensively investigated with respect to structural characterization and with regard to various end-use properties. The relationships between properties and structural characteristics such as crystallinity content and molecular orientation in crystalline and non-crystalline phases were compared with similar relationships in uniaxially oriented polypropylene films. Notable differences between uni- and biaxially oriented films, in particular with regard to non-linear mechanical behavior (tenacity, impact strength, tear strength) could be explained, at least partly, in terms of structural characteristics (molecular orientation and mobility) related to the non-crystalline phase.

    Platelet thromboxane synthetase inhibitors with low doses of aspirin: possible resolution of the "aspirin dilemma" (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-04-29
    Description: Selective pharmacological inhibition of thromboxane A2 synthesis did not prevent arachidonate-induced aggregation of human platelets in vitro. Prevention was instead achieved by a combination of thromboxane A2 inhibitors with low concentrations of aspirin. The latter partially reduced the proaggregatory cyclooxygenase products that accumulated when thromboxane A2 synthesis was blocked. The aspirin concentrations did not affect per se either platelet aggregation or prostacyclin synthesis in cultured human endothelial cells. The combination of thromboxane synthetase inhibitors with low doses of aspirin may offer greater antithrombotic potential than either drug alone.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bertele, V -- Falanga, A -- Tomasiak, M -- Dejana, E -- Cerletti, C -- de Gaetano, G -- New York, N.Y. -- Science. 1983 Apr 29;220(4596):517-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6682245" target="_blank"〉PubMed〈/a〉

    Mechanical action of the intercostal muscles on the ribs (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-04-01
    Description: The external and internal interosseous intercostal muscles were separately stimulated at end-expiratory lung volume in anesthetized dogs. These muscles were all found to elevate the ribs into which they insert. By attaching weights to the ribs, it was determined that the nonlinear compliance of the ribs was responsible for this phenomenon.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉De Troyer, A -- Kelly, S -- Zin, W A -- New York, N.Y. -- Science. 1983 Apr 1;220(4592):87-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6828883" target="_blank"〉PubMed〈/a〉

    Fibronectin binds to some bacteria but does not promote their uptake by phagocytic cells (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-04-08
    Description: The involvement of plasma fibronectin in phagocytosis of bacteria was investigated by testing the binding of fibronectin to several species of bacteria and by evaluating the ability of fibronectin to promote binding and endocytosis of two species of these bacteria by phagocytic cells. Fibronectin binds non-covalently to Gram-positive and Gram-negative bacteria and to yeast but did not appear to be necessary or sufficient for uptake of Staphylococcus aureus and Salmonella typhimurium by several different phagocytic cell types.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Van de Water, L -- Destree, A T -- Hynes, R O -- R01CA17007/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1983 Apr 8;220(4593):201-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6338594" target="_blank"〉PubMed〈/a〉
