1. 11. Influence of fluid shear on primary nucleation of low molecular organic compounds in solution

   Författare :Jin Liu; Åke Rasmuson; Mårten Behm; Ulf Gedde; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Agitation; Primary nucleation; Induction time; Fluid shear; Energy input; Mass transfer; Molecular alignment; Butyl paraben; Curcumin; m-Hydroxybenzoic acid; Solid-liquid interfacial energy; Nuclei critical radius;

   Sammanfattning : In this project, two experimental systems have been set up to study the influence of fluid shear on primary nucleation. In the first set of experiments, in total about 3000 nucleation experiments have been done with butyl paraben/ethanol solutions, curcumin/ethanol solutions and m-hydroxybenzoic acid/1-propanol solutions in capped vials agitated with magnetic stir bars.

3. 12. Management and women's experiences of pregnancies lasting more than 41 gestational weeks

   Författare :Anna Wessberg; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; experiences; hermeneutic; induction; late-term pregnancy; lifeworld; midwifery; perinatal mortality; ; phenomenology; postterm pregnancy; prenatal care; transition;

   Sammanfattning : It is well known that the risks for complications of both the foetus and the mother increase in post-term pregnancy. To date, there is no uniform worldwide guideline for when to induce a pregnant woman who has passed her estimated due date. Little research has been conducted about women’s own experiences of a pregnancy ≥41 gestational weeks. LÄS MER

4. 13. Cytochrome P450 enzymes affected by artemisinin antimalarials-pharmacokinetic and pharmacogenetic aspects

   Författare :Sara Asimus; Göteborgs universitet; []
   Nyckelord :artemisinin; autoinduction; cytochrome P450; induction; inhibition; malaria; metabolism; pharmacogenetics; pharmacokinetics; probe;

   Sammanfattning : With more than 500 million cases and at least 1 million deaths each year, malaria is a major global health problem. The main problem with malaria control is the emerging drug resistance among parasites causing the infection. Consequently, there is an urgent need for new drugs. LÄS MER

5. 14. Industrial Induction Heating - with a focus on multi coil solutions

   Författare :Kenneth Frogner; Industriell Produktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Induction heating; travelling wave; industrial heating; multi coil; TWIH; SM2C;

   Sammanfattning : Most types of materials and components use heating during the manufacturing process, with a large potential for cost and energy savings. Induction heating is the most energy efficient industrial heating technology for many applications, but so far technical limitations has delayed large scale introduction. LÄS MER

7. 15. Influence of Admixtures on Crystal Nucleation of Vanillin

   Författare :Osvaldo Pino-García; KTH; []
   Nyckelord :Crystallization; nucleation; vanillin; admixtures; additives; impurities; induction time; interfacial energy; molecular modelling; interaction energy;

   Sammanfattning : Admixtures like reactants and byproducts are solublenon-crystallizing compounds that can be present in industrialsolutions and affect crystallization of the main substance.This thesis provides experimental and molecular modellingresults on the influence of admixtures on crystal nucleation ofvanillin (VAN).
