  1. 1. Att bli eller inte bli utbränd : ett komplext fenomen bland vårdpersonal på samma arbetsplatser

    Författare :Gabriella Gustafsson; Gunilla Strandberg; Marie Åsberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; burnt out non-burnt out; conscience; healthcare personnel; phenomenological-hermeneutics; stress of conscience; PLSR; 16PF; Nursing; Omvårdnad; omvårdnadsforskning med medicinsk inriktning; Caring Sciences;

    Sammanfattning : The thesis comprises four papers. The overall aim was to illuminate meanings of becoming and being burnt out respectively not becoming or being burnt out. LÄS MER

  3. 2. Regression methods in multidimensional prediction and estimation

    Författare :Anders Björkström; Rolf Sundberg; Philip J Brown; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; regression; prediction; principal compnents regression; ridge regression; partial least squares; Mathematical statistics; Matematisk statistik; matematisk statistik; Mathematical Statistics;

    Sammanfattning : In regression with near collinear explanatory variables, the least squares predictor has large variance. Ordinary least squares regression (OLSR) often leads to unrealistic regression coefficients. Several regularized regression methods have been proposed as alternatives. LÄS MER

  4. 3. Biochemical and spectral characterization of micro- and macroalgae

    Författare :Calle Niemi; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Algae contain many compounds which are of interest to the pharmaceutical, agricultural and food industries, among others. Despite the potential for many applications, a quick, accurate and inexpensive method for characterising algae is lacking. LÄS MER

  5. 4. Theoretical Modeling and Near-Infrared Spectroscopy Monitoring of Vial Lyophilization

    Författare :Mikael Brülls; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in-situ; simulation; monitoring; spectral peak area analysis; near-infrared spectroscopy; lyophilization; moisture; sublimation; vial; mathematical model;

    Sammanfattning : The research documented in this thesis was directed towards lyophilization of pharmaceuticals in vials (vial lyophilization) and it was focused on the design and control of this process. Theoretical modeling has considerable potential to guide experimental studies, thereby decreasing development time and improving the possibilities to achieve an optimal and robust process design.

  7. 5. Understanding the causes of spatial variation in pesticide sorption and degradation at the catchment scale

    Författare :Abdul Ghafoor; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Intensive agricultural practices and use of pesticides, essential to achieve high crop yields, present particular risks to soil and water resources which sustain life. Degradation and sorption of pesticides in soils are both spatially variable and also among the most sensitive factors determining losses to surface water and groundwater. LÄS MER
