    Sammanfattning : The standard model of particle physics can excellently describe the vast majorityof data of particle physics experiments. However, in its simplest form, it cannot account for the fact that the neutrinos are massive particles and lepton flavorsmixed, as required by the observation of neutrino oscillations. LÄS MER

  3. 2. Production and application of fine fractions made of chemical pulp for enhanced paperboard strength

    Författare :Elisabeth Björk; Per Engstrand; Mark Martinez; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : For all kinds of paperboard packages, the bending stiffness of the paperboard is a crucial property. In multi-ply folding boxboard (FBB) grades, this is obtained by placing different stocks in the outer and centre plies of the board. In the outer plies, a stock with a high tensile stiffness is used, typically made from refined kraft pulp fibres. LÄS MER

  4. 3. Radiation dose and image quality in diagnostic radiology : optimization of the dose - image quality relationship with clinical experience from scoliosis radiography, coronary intervention and a flat-panel digital detector

    Författare :Håkan Geijer; Hans Ringertz; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Det är känt att röntgenstrålning kan orsaka cancersjukdomar, hudskador och andra sidoeffekter. Därför är det viktigt och även föreskrivet i lag att strålexpaneringen inom diagnostisk radiologi skall sänkas så långt som möjligt. Detta kallas på engelska ALARA-principen (As Low As Reasonably Achievable). LÄS MER

  5. 4. Exploring the fate of emerging contaminants during hydrothermal regeneration of carbonaceous adsorbents

    Författare :Pierre Oesterle; Stina Jansson; Jerker Fick; Ulrika Rova; Capucine Dupont; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Activated biochars; HTC; regeneration; analytical chemistry; adsorption; degradation; nontarget analysis; wastewater; circular economy; emerging contaminants; surface chemistry; Analytical Chemistry; analytisk kemi; environmental science; miljövetenskap; Pharmaceutics; galenisk farmaci; analytisk materialfysik; analytical material physics; Analytical Pharmaceutical Chemistry; analytisk farmaceutisk kemi;

    Sammanfattning : Wastewater from households and industries commonly contain emerging contaminants that are not easily removed by most wastewater treatment plants. These contaminants can be removed through adsorption onto adsorbents, such as activated carbon or biochars. LÄS MER

  7. 5. Late-life depression from a primary care perspective

    Författare :Karin Fröjdh; Allmänmedicin och samhällsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gerontologi; Gerontology; HSCL-25; outcome; Late-life depression; primary care;

    Sammanfattning : Studies have found that depressive states in old age that do not fulfil the criteria for major depression are clinically important depressive states. These depressive states are common in primary care patients. Therefore, studies of late-life depression from a primary care perspective are needed. LÄS MER
