1. 6. The Internal Flow in Freezing Water Droplets

   Författare :Linn Karlsson; Staffan Lundström; Anna-Lena Ljung; Jasmina Casals-Terré; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Sammanfattning : The aim of this work has been to study the internal flow in freezing water droplets on a cold surface and to investigate the different heat transfer mechanisms involved. This is an interesting topic with a great number of applications, specifically in areas where the prevention of unwanted icing is important, e.g. LÄS MER

3. 7. Geochemical and Mineralogical Characterization of Waste Rocks for Preliminary Mine Drainage Quality Prediction

   Författare :Teemu Karlsson; Lena Alakangas; Päivi Kauppila; Berndt Lottermoser; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mine waste characterisation; mine drainage water; ARD; NRD; aqua regia extraction; ABA test; NAG test; SEM mineralogy; sulfide minerals; risk assessment; Applied Geochemistry; Tillämpad geokemi;

   Sammanfattning : Acid or neutral rock drainage (ARD or NRD) with its attendant elevated concentrations of harmful elements presents one of the main challenges related to the management of waste rocks. Low-quality drainage is a particular issue with respect to mineral deposits containing sulfide minerals, of which pyrite and pyrrhotite are especially prone to produce acidic drainage when exposed to oxygen and water.

4. 8. Geochemical and mineralogical laboratory methods in waste rock drainage quality prediction

   Författare :Teemu Karlsson; Lena Alakangas; Päivi Kauppila; Andrew Barnes; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Extractive waste characterisation; drainage water; ARD; NRD; ABA test; NAG test; SEM; Applied Geochemistry; Tillämpad geokemi;

   Sammanfattning : Harmful substances containing acid or neutral rock drainages (ARD and NRD) are a major challenge related to the management of extractive industry wastes. This issue is particularly related to deposits containing sulphide minerals, which are prone to oxidization under the influence of atmospheric oxygen and water. LÄS MER

5. 9. Pharmacokinetic-Pharmacodynamic Modelling of Anticancer Drugs : Haematological Toxicity and Tumour Response in Hollow Fibres

   Författare :Lena E Friberg; Mats Karlsson; Alan Boddy; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacokinetics Pharmacotherapy; Farmakokinetik Farmakoterapi; PHARMACY; FARMACI; farmakokinetik och läkemedelsterapi; Pharmacokinetics and Drug Therapy;

   Sammanfattning : Established quantitative relationships between dose, plasma concentrations and response [pharmacokinetic-pharmacodynamic (PKPD) models] have a high potential in improving therapeutic indices of anticancer drug therapy and in increasing drug development efficiency. PKPD modelling is a helpful tool for characterising and understanding schedule dependence. LÄS MER

7. 10. Transition towards autonomy and psychological empowerment in self-management, among teenagers with type 1 diabetes

   Författare :Agneta Karlsson; Lena Haglund; Maria Arman; Carina Berterö; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transition; life world; phenomenology; qualitative content analysis; psychological empowerment; teenage diabetes; adolescence.; Caring sciences; Vårdvetenskap;

   Sammanfattning : The general aim of this thesis was to study the transition process from dependency towards anatomy and psychological empowerment among teenagers with type 1 diabetes. Thirty-two teenagers (18 female/14 male) aged 13-17 took part in conversational interviews. The interviews followed a semi-structured question guide. LÄS MER
