    Notizen: In this study, the intracellular concentrations of six elements (mmole/kg dry weight) were directly measured in the muscle fibers of pectoralis major muscles of eight week old, genetically dystrophic and normal chickens by the X-ray microanalysis technique. The extent of muscle degeneration was evaluated by morphometric measurements of muscle fiber diameter and other histological changes. A significant increase in the concentration of intracellular sodium and chlorine was evident in dystrophic muscles. The concentration of intracellular sodium was 127.0 ± 35.0 in the muscle fibers of dystrophic chicks compared to 65.7 ± 16.5 in normal controls. The concentration of chlorine was 90.5 ± 27.5 and 54.1 ± 5.5 in the muscle fibers of dystrophic and normal chicks respectively. The intracellular concentrations of potassium, magnesium, phosphorous, and sulfur remained unchanged in the dystrophic condition. Morphometric studies revealed that the dystrophic pectoralis muscles contain fewer but thicker fibers per unit area compared to normal pectoralis muscles. The importance of these findings are discussed in relation to the results of earlier investigations.

    Beschreibung / Inhaltsverzeichnis: Die Copolymerisation von Acrylnitril und Acrylaten wurde in Dimethylformamid bei hohem Acrylnitril/Acrylat-Verhältnis im Temperaturbereich von -50 bis +10°C durch Lithiumalkoxide initiiert. Die Bedingungen zur direkten Präparation von Spinnlösungen der Copolymere wurden erarbeitet. Das Lösungsspinnen dieser Copolymere durch Orientierungsfällung ergab Fasern mit hohen Festigkeitswerten.
    Notizen: The copolymerization of acrylonitrile with acrylates has been initiated by lithium alkoxides in dimethylformamide at a high acrylonitrile/acrylate ratio over the temperature range from -50 to 10°C. The conditions for a direct preparation of spinning solutions of the copolymers were determined. The solution-spinning of these copolymers by orientational precipitation yielded fibres exhibiting high strength properties.

    Notizen: Both thermal and athermal effects of millimeter-wave radiation on BHK-21/C13 cells were sought using scanning and transmission electron microscopy in conjunction with an in vitro technique that allows direct exposure of monolayer cultures to high average power densities. Culture dishes were irradiated by placing them on the open end of an E- or U-band wave guide. This technique exposes different regions of the cell monolayer lying along the longer axis of the wave guide aperture to varying power densities ranging from zero at each edge to twice the average power density at the center.Cell ultrastructure was unaffected by microwave radiation for 1 hour (41.8 or 74.0 GHz, average power densitites = 320 or 450 mW/cm2, respectively) with or without cooling by rapid recirculation of the culture medium. Temperature in recirculated cultures was held at 37.2 °C, and that in noncooled cultures never exceeded 42 °C during irradiation at either power density. In contrast, cell morphology was affected by microwave exposure whenever irradiation conditions were altered so that the temperature of the monolayer reached or exceeded 44.5 °C. Ultrastructural alterations included breakage of cell processes, progressive detachment of cells from the substrate, increased clumping of heterochromatin in the nuclei, and the appearance of large empty vesicles in the cytoplasm. Such morphological changes resulted from either application of higher average power densities or irradiation at the power densities described above at a higher ambient temperature (〉38.5°C).

    Early Colonization Patterns of Diatoms and Protozoa in Fourteen Fresh-water Lakes (1983)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 30 (1983), S. 0 
    Details
    ISSN: 1550-7408
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie
    Notizen: . Polyurethane substrates were anchored near the surface of 14 lakes in the northern tip of the lower peninsula of Michigan. I wo substrates were removed from each take and taken to the laboratory after 1, 3, 6, 15, and 21 days of exposure. At the laboratory, one substrate was used for determining the number of species of diatoms and the other for protozoa. A cluster analysis of the matrix of Jaccard's coefficients for all diatom samples from all lakes showed that virtually all samples from any given lake consistently clustered together. This indicates that, with respect to species occurrence, distinct and compositionally stable diatom assemblages formed on the substrates in fewer than 21 days. Analysis of all protozoan samples from all lakes did not show such clustering, however, and the correspondence of clusters for protozoan and diatom communities for the 14 lakes was not particularly good. This suggests that the link between the two groups at the species level is not particularly strong during the early phases of artificial substrate colonization.

    Thema: Energietechnik , Geologie und Paläontologie
    Notizen: The implementation of the Resource Conservation and Recovery Act (RCRA) and the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) may be enhanced by wider applications of vadose zone monitoring. More than 50 different vadose zone monitoring techniques are referenced. Fourteen different criteria are established for selecting alternative vadose zone monitoring methods. These monitoring methods are categorized according to premonitoring techniques, sampling methods and nonsampling methods which could be applied in the vadose zone. Two conceptual cases are presented covering vadose zone monitoring at a hazardous waste disposal impoundment. The rationale for the monitoring program at a new impoundment and for an active impoundment is presented. The material constitutes the first phase of a vadose zone monitoring manual.

    Notizen: California navel orange juice, two-stage pulpwash and concentrated orange juice obtained from a commercial processing plant during the 1979–80 processing season were analyzed by chemical, physical and microbiological methods. Statistically significant differences (P 〈 0.01) were found between single-strength orange juice and pulpwash in the concentration of nitrate, sulfate, phenolics, carbohydrates, protein, pectin, UV/VIS absorption characteristics, minerals and carotenes. Seasonal variations were found in carbohydrates, organic acids, minerals, microbiological data, UV/VIS absorption characteristics, carotenoids, protein and phenolics. This report outlines methods of analysis, summarizes analytical results and discusses application of these findings to the detection of pulpwash adulteration of orange juice.

    Notizen: The nitrogen solubility of soy products was determined in water, phosphate buffer, and buffer with urea and/or mercaptoethanol. The water solubilities in decreasing order were: minimally heat processed flours, isolates, heat processed flour, and concentrates. Heat treatment of soy flours increased hydrogen, hydrophobic, and disulfide bonds. The insolubility of isolates and concentrates was due mostly to hydrophobic and hydrogen bonding. The in vitro digestibilities in decreasing order were: isolates, concentrates, heat processed flour, and minimally heat processed flours. PER decreased as disulfide bonding increased except in minimally heat-treated flours. For products with little or no inaccessible disulfide bonding, digestibility increased as hydrogen and hydrophobic bonding increased.

    Semiautomated Method for the Analysis of PSP Toxins in Shellfish (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 49 (1984), S. 0 
    Details
    ISSN: 1750-3841
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft , Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: The method uses an autoanalyzer continuous flow reaction system to oxidize toxin in standard acid extracts of shellfish, prepared for mouse bioassay, to derivatives which are detected by fluorescence. Oxidation is by periodic acid under alkaline (NH4OH) conditions and is followed by acidification by acetic acid. Concentrations of 10 μg/100g toxin and above can be measured with good reproducibility and accuracy: coefficient of variation was 9.5% for samples with 60 μg/100g or greater. Correlation with the mouse bioassay was 0.82 for 204 samples (toxin from 0–2000 μg/100g). The method is proposed to screen shellfish samples for PSP toxins with only samples falling into the range 60–250 μg/100g being subject to the more tedious and expensive mouse bioassay.
