1. UHV-CVD growth of Ge/Si nanostructures
Sammanfattning : This thesis is based on the results concerning the epitaxial growth and characterization of silicon (Si) and germanium (Ge) nanostructures. The growth technique was the Ultra High Vacuum Chemical Vapor Deposition (UHV-CVD) that works in relatively low temperatures and low growth pressures. LÄS MER
2. Epidemiological studies on frailty and its associations with mortality, dementia, and polypharmacy
Sammanfattning : Frailty describes the status of decreased physiological reserves and increased vulnerability to adverse outcomes. As the aging population increases, frailty has become an important public health concern. However, longitudinal studies disclosing the associations of frailty with adverse outcomes over the life course are limited. LÄS MER
3. Development of nonviral gene delivery and of anti-gene reagents
Sammanfattning : Although significant progress has been made in the basic science and applications of various non-viral gene delivery systems, the majority of non-viral approaches are still much less efficient than viral vectors, especially for in vivo gene delivery, Therefore, non-viral gene delivery must be developed in order to increase the efficiency of in vivo delivery. Moreover, a novel anti-gene reagent was developed for sequence-specific gene silencing. LÄS MER
4. Inflammation and Stem Cell Therapy for Stroke
Sammanfattning : Ischemic stroke is a leading cause of death and disability worldwide. Currently, there is no treatment that can promote recovery in the chronic phase. It has been shown that neurogenesis occurs in ischemic striatum in rodents and probably also in humans. LÄS MER
5. Extraction of Metal Values : Thermodynamics of Electrolyte Solutions and Molten Salts Extraction Process
Sammanfattning : Over the past centuries, a number of process routes for extraction of metal values from an ore or other resources have been developed. These can generally be classifiedinto pyrometallurgical, hydrometallurgical or electrometallurgical routes. LÄS MER
