    Notes: Summary Mean relative gas holdup, slip velocity, bubble size distribution, mean specific interfacial area, and volumetric mass transfer coefficient of oxygen were estimated in sparged columns 14 cm in diameter and 380 and/or 390 cm high with two different aerator types (porous plate and injector nozzle) in highly viscous Newtonian (glycerol solutions) and non-Newtonian (CMC solutions) fluids. For the Newtonian liquids the above properties were estimated as function of the viscosity of the liquid. For the non-Newtonian liquids they were determined as function of the fluid consistency index and flow behavior index. Significant differences between Newtonian and non-Newtonian systems appear. In Newtonian medium kL a drops with increasing viscosity and already approaches a constant value at η=40 cP. In pseudoplastic medium kL a varies with the fluid consistency and flow behavior indexes in the entire investigated range. In both of these systems the primary bubble population changes into two or three populations along the reactor: the medium bubbles gradually disappear and small and large bubbles are formed.

    The kinematics of the vortex ring structure generated by a bursting bubble (2000)
    [S.l.] : American Institute of Physics (AIP)

    Notes: The vortex structure created by a bursting bubble has been photographically studied. A vortex model has been constructed, which describes the evolution of the structure, and the phenomenon has been simulated numerically using two two-dimensional vortex blob models. The bubble is situated on a shallow pool of fluid that is on the top face of a vertical cylinder. Two upward-moving vortex rings with colinear axes are formed within 15 ms after bubble rupture. The two rings leapfrog to form a structure consisting of a vortex ring that sheds lobes of fluid that are sometimes similar in appearance to hairpin vortex loops. This evolution occurs within 100 ms of the initiation of bubble rupture, when the ring Reynolds number is approximately 170. The computational model produced images with a close resemblance to the physical structure, and was used to support the theory that the trailing lobes are rotational and consist of the vortex ring that was initially leading. © 2000 American Institute of Physics.

    DIFFERENCES IN BELIEFS ABOUT WORK BETWEEN MANAGERS AND BLUE-COLLAR WORKERS (1979)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of management studies 16 (1979), S. 0 
    Details

    Topics: Economics
    Notes: The beliefs about work of managers and blue-collar workers in the U.S.A. and Scotland were determined through a questionnaire. Both managers and blue-collar workers strongly endorsed humanistic beliefs and were indifferent to the work ethic. Blue-collar workers endorsed more strongly than managers beliefs about worker exploitation and the value of participation. In Scotland, there was a wide difference in the perceived value of leisure between managers and workers. It appears that the Scottish respondents hold fewer independent beliefs than their U. S. counterparts.

    Psychological adjustment in parents of young children with atopic dermatitis: which factors predict parental quality of life? (2004)
    Oxford, UK : Blackwell Science Ltd
    British journal of dermatology 150 (2004), S. 0

    Topics: Medicine
    Notes: Background  Bringing up children with atopic dermatitis (AD) is widely perceived as being stressful because parenting demands considerable time and energy. There have been only a few studies to assess the extent of problems experienced by the parents.Objective  To assess the psychosocial well-being of parents caring for a young child with AD and to examine the relationship between parental quality of life and disease-related and sociodemographic variables.Methods  One hundred and eighty-seven parents of young children with AD attending an inpatient rehabilitation clinic participated in the study. At admission, parents completed a set of questionnaires (assessing health-related quality of life, coping with the disease, family functioning). Dermatologists assessed disease severity using the severity scoring of AD index (SCORAD).Results  In general, parents cope well with their situation. Compared with normal values, high rates of psychological distress were observed in a subsample of parents of children with AD. Parents of children with a higher severity of disease reported a significantly higher impact on family functioning, a greater financial burden and a higher level of disease management. Parental disease management could be predicted by the familial situation, their personal well-being and the severity of disease of their child. Differences attributed to their child's gender or age were not observed.Conclusions  Childhood AD has a profound impact on the emotional and social well-being of many of the parents. The results underline the importance of psychological treatment approaches designed to increase parental well-being and ability to cope with stress and social strain.

    Notes: To assess the quality of hypertension (HTN) care in an urban nurse-managed center (NMC) by chart audits of insured and uninsured (N= 52) African Americans who were managed by nurse practitioners.〈section xml:id="abs1-2"〉〈title type="main"〉Data SourcesA chart audit form was developed by the authors that merged Health Plan Employer Data and Information Set (HEDIS) criteria with the Joint National Committee on Detection, Evaluation, and Treatment of High Blood Pressure (JNC VI) criteria.〈section xml:id="abs1-3"〉〈title type="main"〉ConclusionsThere was near comparable hypertension control among the two groups. No difference was found in systolic blood pressure (BP) control; however, the uninsured group had a slightly greater average diastolic BP compared with the insured group. There was no significant difference in the number of HTN medications or the number of risk factors. A significant difference was found in the number of NP visits per year between the two groups; the uninsured group averaged 3.2 more visits per year.
