    Notes: Pollen embryos were obtained from eight genotypes and viable green plants were regenerated from four genotypes in an anther-culture experiment with 165 genotypes of Phleum pratense L. Formation of proembryos inside the cultured anthers during the first 10—12 days was significantly influenced by genotypes and by the type of nutrient media. Primary embryos developed into multiple secondary embryos before regeneration of plants. Among a total of 62 plants regenerated, only 13 were albinos. Of the green regenerants, 11 were triploid while 35 were hexaploid when DNA-content was measured by flow cytometry. Eight plants with a triploid DNA-content did possess the triploid chromosome number of 21. Triploid and hexaploid regenerants from two different parents showed simplified isozyme (GPI and PGD) banding patterns relative to that of their parents.

    Straight-Line Intercept Method in Aquifer Volume Calculations (1992)
    Oxford, UK : Blackwell Publishing Ltd
    Ground water 30 (1992), S. 0 
    Details

    Notes: Volume calculations in various aspects of ground-water resources evaluation play a significant role. However, these calculations are made by different classical techniques, each of which employs the finite element concept. A common requirement in these techniques is the adaptation of a basic height—like contour interval. The accuracy of the estimated volume is influenced by the subjectivity on the part of the person doing the contouring on a specified contour interval. It is observed that there is a linear relationship between the contour interval and the estimated volume. The basic idea of this paper is to use a simple drawing procedure of a few points of different contour intervals versus the resulting volumes. A regression line is fitted through the scatter of these points. The best volume estimate corresponds to zero contour interval, i.e., the intercept of the straight line with the volume axis. This technique provides a common basis in that different researchers arrive at exactly the same conclusion for a given data set. The proposed method is verified by calculating the reservoir volume of a laboratory dam model with the known reservoir volume. It was found that the estimated volume was off by only 5% of the measured one. Further applications of the method are given for some observed data from the Floridan aquifer and a Black Hills dam reservoir.

    Frequency of nasal and wound isolates of Staphylococcus aureus associated with TSST-1 production in Jordanian population (2000)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS immunology and medical microbiology 27 (2000), S. 0

    Notes: A total of 110 Staphylococcus aureus isolates were obtained from nasal carriers and wound infections of Jordanian population. The isolates were identified by cultural and biochemical methods. The nasal carrier rate of S. aureus among individuals was 22.7%. In comparison with the nasal S. aureus isolates the wound isolates did not produce significantly more virulence factors except DNase. Toxic shock syndrome toxin-1 production was higher among the S. aureus nasal isolates (40%) as compared with the wound isolates (26%) detected by an ELISA method which proved to be uniformly more sensitive than the immunodiffusion optimal sensitivity plate (OSP) method.

    Descriptive Sensory Profiling for Optimizing the Formula of a Peanut Milk-Based Liquid Coffee Whitener (1993)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 58 (1993), S. 0 
    Details
    ISSN: 1750-3841
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition , Process Engineering, Biotechnology, Nutrition Technology
    Notes: A liquid coffee whitener was formulated using peanut milk as a substitute for sodium caseinate and water. Sensory quality of the formulation was evaluated using a descriptive panel. Six sensory attributes were significantly (p 〈 0.05) affected by the amounts of peanut milk, oil and corn syrup solids in the formulations. The maximum amount of peanut milk for an optimum formulation was 40%. The maximum fat content increased from 6% to 9% as peanut milk was decreased from 40% to 20%. A concentration of 2–9% corn syrup solids could be used with 20–40% peanut milk. Acceptable formulations within the optimum region contained 6% oil in combination with 40% peanut milk and 2% corn syrup solids or 20% peanut milk and 8% corn syrup solids.

    An investigation of acceleration waves in a perfectly conducting magnetohydrodynamic fluid (1988)
    Springer
    Zeitschrift für angewandte Mathematik und Physik 39 (1988), S. 634-648 
    Details
    ISSN: 1420-9039
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics , Physics
    Notes: Abstract This paper discusses the propagation of discontinuities in a perfectly conducting magnetohydrodynamic fluid, the model having been proposed by P. H. Roberts [1] in the context of neutron stars. P. H. Roberts [1] obtained a stability criterion which was subsequently reproduced by B. Straughan [3] using a discontinuity analysis but in the process the resulting sixth order secular equation decomposed into a product of quadratic and quartic polynomial factors. The first section of this paper investigates the reason for this factorization and the latter sections examine the nature of the equations governing the behaviour of the discontinuity amplitudes. The presence of the magnetic field effectively makes the fluid non-isotropic and so the determination of amplitude equations is non standard although they finally prove to be of Bernoulli type.

    Analyzing spatial disparities in access to health care: A methodology with application in Bangladesh (1985)
    Springer
    GeoJournal 10 (1985), S. 91-107 
    Details
    ISSN: 1572-9893

    Topics: Geography
    Notes: Abstract This paper develops a methodology for analyzing spatial disparities in access to health care in situations where the data base is limited, and applies it in the context of Bangladesh. The proposed indirect measures of inpatient and outpatient service utilization, and of quality of available services, seem to provide reasonably accurate, consistent, and interpretable results; these indices are combined into a composite index of relative access to health care. The form of the composite index and its components permits the incorporation of Sopher's disparity index into the methodology for measuring urban-rural disparities in relative access to health care. The empirical analysis based on subdivision level data revealed that Bangladesh's health care delivery system is, in general, characterized by extremely low level of access and a high degree of disparity in favor of urban areas, especially in terms of inpatient services. Spatial patterns of relative access and urban/rural disparity were perused through cartographic and statistical analyses; although clear-cut regional patterns did not emerge, the considerable spatial variations could be explained largely with reference to urbanization and density of population. Assuming improved level of access and minimal urban/rural disparity as basic policy goals a method to prioritize spatial units for future allocation of health sector resources is recommended.

    Spatial systems approach to sustainable development: A conceptual framework (1993)
    Springer
    Environmental management 17 (1993), S. 179-186 
    Details
    ISSN: 1432-1009
    Keywords: Development ; Environment ; Environmental accounting ; Resource ; Spatial System ; Sustainability ; Sustainable development
    Source: Springer Online Journal Archives 1860-2000

    Notes: Abstract Even though “sustainable development” seems to have emerged as the development paradigm of the 1990s, a great deal of vagueness still surrounds the meaning, definition, and theoretical underpinnings of the concept. There is also a general lack of emphasis on the spatial dimension of sustainable development when developing relevant conceptual or environmental accounting frameworks. In clarifying the concept, this article proposes a definition that explicitly incorporates the temporal as well as the spatial dimension of sustainability. It also develops a logically consistent conceptual framework for the analysis and evaluation of sustainable development, following a spatial systems approach. Five interconnected aspatial subsystems or subsets of a spatial system are identified and their respective operational dimensions discussed. A proposed composite index calleddegree of stainable development (DSD) and its five component indicators are also outlined. The difficulties involved in operationalizing the DSD measure and the conceptual framework are noted, and the various tasks that need to be undertaken in this regard are specified. It is concluded that future research utilizing the proposed conceptual framework should not only foster the development of appropriate methodologies for the comparative evaluation of sustainable development at global, national, or regional scales, but also offer insights to appropriate decision makers at various levels regarding available options and alternative actions for the healthy development of their respective societies.
