2. 1. Energy and intensity modulated radiation therapy with electrons

   Author : Lennart Olofsson; Mikael Karlsson; Magnus Karlsson; Björn Zackrisson; Erik Traneus; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; Radiation therapy; Conformal therapy; IMRT; Electrons; Electron treatment head; Electron MLC; Bremsstrahlung reduction; Integral dose; Penumbra; Output factor; Strålningsvetenskap; Radiation biology; Strålningsbiologi; radiofysik; radiation physics;

   Abstract : In recent years intensity modulated radiation therapy with photons (xIMRT) has gained attention due to its ability to reduce the dose in the tissues close to the tumour volume. However, this technique also results in a large low dose volume. READ MORE

4. 2. Characteristics of EBV-infected B cell lines and B-CLL clones which determine their interaction with lymphocytes

   Author : Javier Federico Avila-Carino; Karolinska Institutet; Karolinska Institutet; []
   Keywords : EBV; Burkitt Iymphoma; CLL; MLC; antiviral response phenotype; cytokines.;

   Abstract : The results concerning T Iymphocyte mediated recognition of Epstein-Barr virus (EBV) carrying Burkitt Iymphoma (BL) cell lines and EBV-infected chronic Iymphocytic leukemia (CLL) B cells contribute to the understanding of the generally harmless host-EBV interaction and may be extrapolated to the fate of normal B cells after EBV infection. The phenotype of EBV negative BL lines resembles resting B cells. READ MORE

5. 3. Thermal and State-of-Charge Balancing of Batteries using Multilevel Converters

   Author : Faisal Altaf; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal balancing; Convex optimization; DC-link ripple; Battery ripple; Battery control; Hybrid electric vehicles.; Multilevel converter; Cell balancing;

   Abstract : Driven by the needs to reduce the dependence of fossil fuels and the emissions of conventional vehicles there has in recent years been an increasing interest in battery-powered electrified vehicles (xEVs). In xEVs, the battery pack, built from many small cells, is one of the most expensive components in the powertrain. READ MORE

6. 4. Beam Modelling for Treatment Planning of Scanned Proton Beams

   Author : Peter Kimstrand; Bengt Glimelius; Erik Traneus; Nina Tilly; Anders Ahnesjö; Thomas Bortfeld; Uppsala universitet; []
   Keywords : Radiation sciences; proton therapy; treatment planning; beam modelling; dose calculation; Monte Carlo; Strålningsvetenskap;

   Abstract : Scanned proton beams offer the possibility to take full advantage of the dose deposition properties of proton beams, i.e. the limited range and sharp peak at the end of the range, the Bragg peak. READ MORE

7. 5. Experimental studies of human fetal liver cells : in regard to in utero hematopoietic stem cell transplantation

   Author : Bim Lindton; Karolinska Institutet; Karolinska Institutet; []
   Keywords : In utero transplantation; fetal liver cells; mixed lymphocyte culture; CD3; CD56; HLA class II; parvovirus B 19 capsids; corticosteroids; cytotoxic drugs; colony formation.;

   Abstract : Successful in utero hematopoietic stem cell transplantation represents a potential step forward in the management of patients with severe inherited hematological, metabolic and immunological disorders. Animal data from a number of species have demonstrated evidence of engraftment, but to date the only effective in utero transplantations (IUTx) in humans have been performed in fetuses with severe immunodeficiencies, suggesting that the fetal immune system play a vital role in the success or failure of in utero transplantation.
