1. Earthquake Sources, the Stress Field and Seismic Hazard : A Study in Eritrea and its Surrounding
Abstract : Presented in this thesis are some basic concepts and applications of seismic hazard analysis and the elements that influence the amplitude and geometric attenuation of earthquake ground motion. This thesis centers on the identification of the styles of failure, focal mechanisms, and the state of regional stress in the study area. READ MORE

2. Undrained shear strength in clay slopes - Influence of stress conditions. A model and field test study
Abstract : To counteract natural hazards such as landslides, current methods for evaluation of soil properties as a mean for determining the safety level of natural slopes need to be refined. The empirical relationships used for estimation of the undrained shear strength from piezocone and field vane test are based on the stress conditions valid for horizontal ground and normally consolidated or slightly overconsolidated soil.

3. Relaxation and nanomechanical studies of the vickers residual stress field in glass
Abstract : The Vickers residual stress field (VRSF) in soda-lime glass results from the elastic-plastic contact event that takes place when a Vickers diamond pyramid is loaded onto the surface of the material in an indentation cycle. The importance of elastic-plastic indentation lies in the contact damage that it gives rise to in the surface of the glass. READ MORE

4. Martensitic Transformations in Steels : A 3D Phase-field Study
Abstract : Martensite is considered to be the backbone of the high strength of many commercial steels. Martensite is formed by a rapid diffusionless phase transformation, which has been the subject of extensive research studies for more than a century. READ MORE

5. Maternal Separation in Rats : An Experimental Model for Long-Term Effects of Early Life Experiences on Neurochemistry, Voluntary Ethanol Intake and Exploration and Risk Assessment Behavior
Abstract : The period of early life is important for the development of individual brain function and behavior. Human studies have shown altered vulnerability to develop psychopathology and/or excessive drug intake, possibly leading to dependence, as a consequence of early life experiences. READ MORE
