  1. 1. Cardiac muscle injury in children and experimental animals. Reflections in ECG, especially high-resolution electrocardiography

    Författare :Rolf Bennhagen; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Kardiovaskulära systemet; Cardiovascular system; signal-averaging ECG; ischaemia; cardiac transplantation; Pediatri;

    Sammanfattning : Background and Methods: Signal-averaging ECG (SAECG), a bioelectrical processing method, is a further development of the conventional ECG. SAECG can detect voltage potentials in the microvolt range and provide a noise-reduced determination of QRS duration. Extended frequency spectra can be analysed. LÄS MER

  3. 2. Between crisis and opportunity : Livelihoods, diversification and inequality among the Meru of Tanzania

    Författare :Rolf Larsson; Sociologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sociology of labour; Meru; Tanzania; Arusha; peasants; sociology of enterprise; family farmers; smallholders; coffee production; income diversification; de-agrarianisation; agricultural intensification; inequality; social differentiation; economic liberalization.; Sociology; Agricultural economics; Sociologi; Arbetslivssociologi; företagssociologi; Lantbruksekonomi;

    Sammanfattning : Sustained high population growth rates are radically altering the livelihood conditions for small farmers in sub-Saharan Africa. In one of the most fertile and densely settled areas of East Africa, Mount Meru in Northern Tanzania, the size of the population has increased nearly tenfold within the last century. LÄS MER

  4. 3. An Experimental and Theoretical Study of Decentralized Gas Fired Liquid Heating

    Författare :Rolf Christensen; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; liquid heating.; efficiency; environmental impact; emissions; corrugated tube; heat transfer augmentation; heat transfer enhancement; energy conservation; decentralized heating; Natural gas; steam replacement; gas firing; Carbochemistry; petrochemistry; fuels and explosives technology; Petrokemi; bränslen; sprängämnen;

    Sammanfattning : The effects on the energy situation in industry when gas fired liquid heaters replace steam have been determined by energy surveys performed in a brewery and a slaughterhouse, measurements of the performance and emissions from liquid heaters installed in these industries, and theoretical analyses of the potential energy saving. The theoretical study in the first part of the project provides information that allows assessment of the effects on the energy situation, of part or complete conversion to decentralized heating, under the conditions prevailing in the industries concerned.

  5. 4. Resonant Laser Techniques for Combustion and Flow Diagnostics

    Författare :Rolf Fritzon; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; species; laser diagnostic techniques; temperature imaging; polarization spectroscopy; stimulated emission; DFWM; Fysik; Physics; turbulent mixing; LIF; Fysicumarkivet A:1998:Fritzon;

    Sammanfattning : This thesis presents results from two areas of research. Firstly, the resonant coherent laser techniques polarization spectroscopy (PS), degenerate four-wave mixing (DFWM) and stimulated emission (SE) have been developed in the general field of combustion diagnostics. LÄS MER

  7. 5. Patrullerande polisers yrkeskultur

    Författare :Rolf Granér; Socialhögskolan; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sociology of labour; Occupational culture; Organizational culture; Police discretion; Police personnel; Police patrol; Police work attitudes; sociology of enterprise; Arbetslivssociologi; företagssociologi; Poliskunskap;

    Sammanfattning : Using ethnographical methods, this thesis examines the prevalence and character of an occupational culture among patrolling police in terms of frames of reference, conduct and attitudes, a culture which overrides or is in opposition to the official mandate of the police force. It is suggested that the occupational culture of the patrolling police should not be regarded as a homogenous culture but be seen as describing a continuum from a legalistic to a more autonomous perspective.
