    Abstract : Degradation of water resources has become one of the most pressing global concerns currently facing mankind. Constructed Wetlands (CWs) represent a concept to combat deterioration of water resources by acting as buffers between wastewater and receiving water bodies. READ MORE

  4. 4. Psychological perspectives on fear of birth heterogeneity, mechanisms and treatment

    University dissertation from Sundsvall : Mid Sweden University

    Author : Elisabet Rondung; Mittuniversitetet.; [2018]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : Although it is medically safe to give birth in most western countries, the vast majority of pregnant women experience some kind of anxiety, fear or worry in relation to their pregnancy or the upcoming childbirth. Most pregnant women find ways of coping with these issues but, for many, fear of birth is a significant source of distress during pregnancy, with negative consequences both when giving birth and in the postpartum period.

  5. 5. Probabilistic treatment planning based on dose coverage How to quantify and minimize the effects of geometric uncertainties in radiotherapy

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : David Tilly; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radiotherapy; treatment simulation; probabilistic planning; dose calculation; probabilistic optimization; statistical shape model; Medicinsk radiofysik; Medical Radiophysics;

    Abstract : Traditionally, uncertainties are handled by expanding the irradiated volume to ensure target dose coverage to a certain probability. The uncertainties arise from e.g. the uncertainty in positioning of the patient at every fraction, organ motion and in defining the region of interests on the acquired images. READ MORE
