1. Plasticity Driven Damage and Void Growth
Sammanfattning : Plasticity induced damage evolution is considered using a thermodynamical approach. Different postulates on how to include the effects of damage in the constitutive equations have been studied. The results reveal that a mapping, similar to that of the stress, of both the kinematic and isotropic hardening variables is to be preferred. LÄS MER
2. Failure of Sandwich Structures with Sub-Interface Damage
Sammanfattning : .... LÄS MER
3. Helium Filled Bubbles in Solids : Nucleation, Growth and Swelling
Sammanfattning : When nuclear fuel, fabricated for the purpose of transmuting spent fuel is irradiated, significant amounts of He is produced from alpha particles mainly emitted when 242Cm decays into 238Pu. From irradiation experiments it is known that the presence of He in the solids alters the swelling behaviour of the material. LÄS MER
4. Hepatocyte growth factor : Studies on local and systemic release and effects during infectious disease; in vivo and in vitro
Sammanfattning : The interaction of mesenchymal and epithelial cells that occurs after organ injuries results in enhanced production of cytokines, such as hepatocyte growth factor (HGF). HGF is a glycoprotein with unique properties that contribute to wound healing after injuries. LÄS MER
5. Ribonucleotide reductase and DNA damage
Sammanfattning : A prerequisite for a multicellular organism to survive is the ability to correctly replicate and repair DNA while minimizing the number of heritable mutations. To achieve this, cells need a balanced supply of deoxyribonucleoside triphosphates (dNTPs), the precursors for DNA synthesis. LÄS MER
