    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Central America; Discharge; Flow-duration curve; Fuzzy regression; GLUE; Model evaluation; Non-stationarity; Observational uncertainty; Precipitation; Quality control; Rating curve; Regionalisation; Uncertainty estimation; Ungauged basins; Water resources; Avbördningskurva; Centralamerika; GLUE; icke-stationaritet; kvalitetskontroll; modellutvärdering; nederbörd; observationsosäkerheter; avrinningsområden utan vattenfö-ringsdata; oskarp regression; osäkerhetsuppskattning; regionalisering; varaktighetskurva; vattenföring; vattenresurser; Hydrology; Hydrologi; Hydrology; Hydrologi;

    Sammanfattning : Knowledge about spatial and temporal variability of hydrological processes is central for sustainable water-resources management, and such knowledge is created from observational data. Hydrologic models are necessary for prediction for time periods and areas lacking data, but are affected by observational uncertainties. LÄS MER

  3. 17. Hooked on Markets : Revaluing Coastal Fisheries in Liberal Rural Capitalism

    Författare :Alexander Dobeson; Patrik Aspers; Vessela Misheva; Koray Çalışkan; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; marketisation; economisation; valuation; evaluation; practice theory; technology; quality; relational ethnography; natural resources; fisheries; rural capitalism;

    Sammanfattning : Natural resource–based economies are typically embedded in rural networks of production. In recent years, however, the privatisation of access rights and the organisation of markets have substantially transformed some of these rural economies. LÄS MER

  4. 18. Undervisnings- och utbildningsplanering - för vem? : En studie av ingenjörsutbildning vid en svensk högskola

    Författare :Elvy Westlund; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Education; Higher Education; engineering education; evaluation; motivation; personality; learning styles; course planning; student involvement; quality; Pedagogik; Education; Pedagogik; pedagogik; Education;

    Sammanfattning : This dissertation points at some of the consequences of the changes in the economic and social conditions of the second half of the twentieth century that have had a great influence on higher education. A growing number of students are attending our universities and at the same time the Government is asking for greater quality and efficiency in education. LÄS MER

  5. 19. Development of methods for evaluation and optimization of chest tomosynthesis

    Författare :Angelica Svalkvist; Göteborgs universitet; []
    Nyckelord :Chest tomosynthesis; Evaluation; Optimization; Simulation; Image Quality; Dosimetry; Dose reduction; Nodule simulation; Validation;

    Sammanfattning : Tomosynthesis is a low-dose technique that has attracted increasing interest from the medical imaging community during the past decade. Tomosynthesis refers to the technique of acquiring a number of projection radiographs using extremely low exposure over a limited angular range, and using these radiographs to reconstruct slices of the imaged object.

  7. 20. The extent of gynaecological cancer : Evaluation, outcome and quality of life

    Författare :Björg Jónsdottir; Karin Stålberg; Inger Sundström Poromaa; Håkan Ahlström; Päivi Kannisto; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ovarian cancer; endometrial cancer; cytoreductive surgery CRS ; PET MRI; MRI; Peritoneal cancer index PCI ; myometrial invasion MI ; quality of life.; Medicinsk vetenskap; Medical Science;

    Sammanfattning : The overall aim of this thesis was to enhance treatment planning for gynaecological cancer patients and identify women that are more likely to have impaired quality of life (QoL) after treatment. In a retrospective cohort study on ovarian cancer, the peritoneal cancer index (PCI) was examined in relation to incomplete cytoreductive surgeries (CRS) and surgical complications (n=167).
