2. 1. Optimizing Chemotherapy in Childhood Acute Myeloid Leukemia

   Author : Josefine Palle; Gudmar Lönnerholm; Britt-Marie Frost; Rolf Larsson; Henrik Schröder; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; childhood; acute myeloid leukemia; drug resistance; pharmacokinetics; chromosomal abnormalities; Down syndrome; MLL-rearrangement; t 9; 11 ; Paediatric medicine; Pediatrisk medicin;

   Abstract : Despite major advances in our understanding of the biology of childhood acute myeloid leukemia (AML) and the development of new cytotoxic drugs, the prognosis of long-term survival is still only 60-65 %.In the present research, we studied the pharmacokinetics of drugs used in the induction therapy of childhood AML and performed in vitro drug sensitivity testing of leukemic cells from children with AML.

4. 2. Critical degrees of saturation at freezing of porous and brittle materials

   Author : Göran Fagerlund; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resistance; freezing mechanism; freezing test method; pore size distribution determination ; saturation degree of ; water absorption; frost;

   Abstract : This thesis is based on experimental work carried out during the period 1968-1972. The whole investigation is sponsored by the Swedish Council for Building Research and has been performed at the department of Building Materials at the Lund Institute of Technology. READ MORE

5. 3. Moisture Conditions and Frost Resistance of Concrete in Hydraulic Structures

   Author : Martin Rosenqvist; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic Structures; Hydro Power; Concrete Dams; Concrete; Frost Resistance; Scaling; Spalling; Moisture Absorption; Macroscopic Ice Lens Growth;

   Abstract : Owing to the winter conditions in Sweden, the effects of frost action may have a considerable impact on the deterioration of concrete. Both superficial and internal damage, which are suspected to have been caused by frost action, have been found in concrete in hydraulic structures. READ MORE

6. 4. Frost-induced deterioration of concrete in hydraulic structures : Interactions between water absorption, leaching and frost action

   Author : MARTIN ROSENQVIST; Avdelningen för Byggnadsmaterial; []
   Keywords : Vattenbyggnader; Dammar; Betong; Cement; Vattenabsorption; Vattenmättnadsgrad; Nedbrytning; Frostbeständighet; Spjälkning; Makroskopisk islinsbildning; Urlakning; Synergi; Hydraulic structures; Dams; Concrete; Cement; Water absorption; Degree of saturation; Deterioration; Frost resistance; Spalling; Macroscopic ice lens growth; Leaching; Synergy;

   Abstract : Frost deterioration of concrete can result in severe consequences to the safety, durability and functionality of a structure since it impairs the strength of the concrete. Frost damage may occur to structures that are in contact with water and subjected to frost action. READ MORE

7. 5. The influence of ageing on the salt-frost resistance of concrete

   Author : Peter Utgenannt; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materiallära; materialteknik; Building construction; Material technology; freeze thaw testing; hydration; field exposure; carbonation; drying; Byggnadsteknik; ageing; salt-frost resistance; Concrete;

   Abstract : Abstract This thesis presents the results of an investigation of the influence of ageing on the salt-frost resistance of concrete. The ageing mechanisms investigated were hydration, drying and carbonation. READ MORE
