2. 16. Acute Mastoiditis in Children – A National Study in Sweden

   Author : Frida Enoksson; Lund näs- och halssjukdomar Öron-; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pneumococcal conjugate vaccine; surgical treatment; guidelines; paediatric; acute mastoiditis;

   Abstract : One of the greatest threats to society today is the development of bacterial resistance to antibiotics. It is commonly accepted that this is mainly due to the use of antibiotics. Acute otitis media (AOM) is responsible for the highest number of antibiotic prescriptions to children although it is in most cases a self-limiting disease. READ MORE

4. 17. Exploring nanosystems for biomedical applications focusing on photodynamic therapy and drug delivery

   Author : Vladimir Kirejev; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Photodynamic therapy; PDT enhancement; Nitric oxide; NO-based PDT; Targeted drug delivery; Galectin-3; mTHPP; Cyclodextrin; CD-mTHPP conjugate; PpIX AuNP combination; Two-photon microscopy; FLIM; Cell phototoxicity; Ex vivo skin;

   Abstract : The increasing incidences of cancer and related deaths call for the development of new and improved treatment modalities. Photodynamic therapy (PDT) today is an alternative to conventional treatments, but has limitations. This thesis explores different nanosystems with aim to improve PDT focusing on spectroscopic and ex vivo studies. READ MORE

5. 18. Partitioned methods for time-dependent thermal fluid-structure interaction

   Author : Azahar Monge; Numerisk analys; []
   Keywords : thermal FSI; Conjugate heat transfer; Domain decomposition; Time adaptivity; Coupled problems; multirate;

   Abstract : The efficient simulation of thermal interaction between fluids and structures is crucial in the design of many industrial products, e.g. turbine blades or rocket nozzles. READ MORE

6. 19. Carcinogenic polycyclic aromatic hydrocarbons : role of human glutathione transferases in conjugate formation and DNA protection

   Author : Kathrin Sundberg; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Polycyclic aromatic hydrocarbons (PAHs) are widespread mutagenic and carcinogenic environmental pollutants, which requires metabolic activation to electrophilic intermediates and subsequent covalent binding to critical targets in DNA to elicit their biological activity. Bay- and fjord region diol epoxides (DEs) have been identified as the ultimate mutagenic and carcinogenic metabolites of PAHs. READ MORE

7. 20. On Methods for Solving Symmetric Systems of Linear Equations Arising in Optimization

   Keywords : NATURVETENSKAP; NATURAL SCIENCES; symmetric system of linear equations; method of conjugate gradients; quasi-Newton method; unconstrained optimization; unconstrained quadratic optimiza- tion; Krylov subspace method; unnormalized Lanczos vectors; minimum-residual method; symmetriska linjära ekvationssystem; konjugerade gradientmetoden; kvasi- Newtonmetoder; optimering utan bivillkor; kvadratisk optimering utan bivillkor; Kry- lovunderrumsmetoder; icke-normaliserade Lanczosvektorer; minimum-residualmetoden; Mathematics; Matematik;

   Abstract : In this thesis we present research on mathematical properties of methods for solv- ing symmetric systems of linear equations that arise in various optimization problem formulations and in methods for solving such problems.In the first and third paper (Paper A and Paper C), we consider the connection be- tween the method of conjugate gradients and quasi-Newton methods on strictly convex quadratic optimization problems or equivalently on a symmetric system of linear equa- tions with a positive definite matrix.
