    The Neutral Lipids of Paramecium tetraurelia: Changes with Culture Age and the Detection of Steryl Esters in Ciliary Membranes (1983)

    Notes: Neutral lipids, particularly triglycerides, accounted for the major decrease in the total lipid content in Paramecium cells that occurs with culture age. Sterols, triglycerides, and steryl esters were the major classes of neutral lipids in cells and isolated cilia. Free as well as high concentrations of esterified sterols were detected in purified ciliary membrane preparations. Stigmasterol and 7-dehydrostigmasterol were the major components of both free and esterified sterols of cells and cilia; however, when cholesterol was present in the growth medium, it was desaturated to 7-dehydrocholesterol and incorporated into cellular and ciliary lipids. Free fatty acids from cells and triglycerides from cells and cilia were low in polyunsaturated fatty acids and reflected the composition of fatty acids in the culture medium. An exception was the reduced concentration of stearate in triglycerides from whole cells. Greater than 50% of triglyceride fatty acids from cilia were saturated. The fatty acid compositions of cellular triglycerides and ciliary steryl esters did not change with culture age, but those of cellular steryl esters and ciliary triglycerides did change. In comparison with phospholipids, these neutral lipid fatty acid compositional changes were smaller. The sensitivity of these stigmasterol-containing cells to polyene antibiotics indicated that they were killed by nystatin 〉 filipin 〉 amphotericin B. The unexpected finding of high concentrations of steryl esters in ciliary membrane preparations is discussed.

    Management of technology in traditional industries: a pilot study in ten Belgian companies (1983)

    Notes: Empirical Research about management of innovation has mainly been limited to the Anglo-Saxon world. In this paper the author reports on a pilot study, which is part of a larger project, in ten small and medium-sized Belgian companies, all of them active in rather mature industries. The study concerned aspects of idea generation, problem-solving, project selection, and some organizational aspects of the innovation process. An interesting hypothesis resulting from this study is that innovation is mainly an incremental process along a natural trajectory characteristic for the subindustry to which the company belongs, and that the selection process is for the majority of these companies only a minor problem.

    CHANGES IN PHYSICAL AND CHEMICAL VARIABLES IN A NEW RESERVOIR DUE TO PUMPED STORAGE OPERATIONS (1982)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of the American Water Resources Association 18 (1982), S. 0

    Notes: : Information on biologically important physical and chemical variables is presented for Lake Oconee, a newly impounded pumped storage reservoir in Georgia. During its first summer, when no pumping occurred, temperature, oxygen, pH, inorganic nitrogen, and phosphorus were vertically stratified with severe hypolimnetic oxygen depletion. During the second summer, when pumped storage was in operation, more homogenous vertical profiles, generally higher oxygen, and lower dissolved nutrient concentrations were observed. These pumped storage effects were observed at all stations, rather than being confined to the immediate vicinity of the dam.

    The influence of elevated nitrate concentration on rate of leaf decomposition in a stream (1983)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: SUMMARY. 〈list xml:id="l1" style="custom"〉1Leaf decomposition was compared in two streams at the Coweeta Hydrologic Laboratory, North Carolina. U.S.A. One stream drains an undisturbed hardwood watershed, while the other drains a successional watershed subject to an insect outbreak. The successional watershed has elevated nitrate concentrations in the streamwater.2Both black locust (Robinia pseudo-acacia) and sweet birch (Betula lenta) leaf litter decomposed 2.8 times more rapidly in the stream with high nitrate concentrations.3The more rapid decay rates appeared to be partly due to accelerated microbial processing in response to nitrate enrichment, because microbial biomass (as ATP) was higher in the nitrate-enriched stream.4At each point in time, nitrogen and phosphorus content of the litter was lower in the high nitrate stream; however, there was no significant difference in nitrogen or phosphorus content at the same state of leaf decay in the two streams.

    HOW IDEOLOGIES SUPPLANT FORMAL STRUCTURES AND SHAPE RESPONSES TO ENVIRONMENTS (1982)
    Oxford, UK : Blackwell Publishing Ltd

    ISSN: 1467-6486

    Topics: Economics
    Notes: Observations of nineteen hospitals show how organizational ideologies are manifested and sustained by beliefs, stories, languages, and ceremonial acts. The data indicate that harmonious ideologies accompany simple structures, but that discordant ones accompany elaborate structures. Through their effects on people and structures, ideologies guide organizations’responses to external threats.

    TWO STRUCTURAL MODELS FOR THE WESTERN FLANK OF THE BRABANT MASSIF (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical prospecting 32 (1984), S. 0 
    Details
    ISSN: 1365-2478
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geosciences , Physics
    Notes: This paper is concerned with an interpretation of the Bouguer anomaly on the Western flank of the Brabant Massif (Belgium). The position, shape, and density contrast of elementary bodies in the upper part of the earth's crust are determined in a purely numerical manner. A batholith-like body and a basin-type structure both adequately account for the observed surface field, at least from a one-sided geophysical and mathematical point of view. Since seismological control is lacking the two models are representative of the ambiguity and indeterminacy of the definitions of the geologic cause of the anomalous features, if the data are restricted to gravity information alone.

    Effects of Added Calcium on Texture and Quality of Canned Jalapeno Peppers (1981)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 46 (1981), S. 0

    Notes: Jalapeno peppers were canned and treated with calcium chloride, calcium hydroxide, and calcium lactate. Concentrations of 0.2, 0.3, and 0.4% of calcium were used. After 3 months of storage time, the peppers were evaluated for texture, quality, and nutritional composition. Calcium hydroxide was an inadequate firming compound in this experiment because of its neutralizing effect on the acid content and the precipitation found in the can after storage. Calcium chloride at a concentration of 0.2% was found to be the most desirable firming compound because under the test conditions it did not impart a bitter taste and because its solubility properties are better than those of calcium lactate. Higher concentrations failed to significantly increase the firmness of peppers. The treatments produced no adverse effects on the flavor or the vitamin and mineral content, with the exception of calcium, in canned jalapeno peppers.

    Notes: Carrot pie fillings were prepared from carrots that did not meet fresh market standards but were otherwise of good quality. The pie fillings were prepared by mixing carrot puree, sugar, salt, and ground spices or oil extract spices. Nutrient composition analysis showed that vitamin A was five times higher in carrot pie fillings than in pumpkin pie filling. Thiamin, niacin, and total carbohydrates were higher in carrot pie fillings. Sensory panel scores show that carrot pie was preferred over pumpkin pie and ground spices over oil extract spices. The results of this work indicate that an acceptable carrot pie filling of equal or better nutritional value than pumpkin pie can be prepared.
