21. Seasonal partial migration of cyprinids - Causes and consequences
Sammanfattning : Partial migration is a common phenomenon in animals but has mostly been studied in birds. However, partial migration of cyprinid fish from lakes into streams during winter is a wide-spread phenomenon. LÄS MER
22. Bedroom Politics. How family policies affect women’s fertility and union formation decisions
Sammanfattning : Most studies on policies’ effect on fertility depart from the assumption that fertility decisions are taken within unions, by partners who behave altruistically towards each other. This study argues that such a focus misses a fundamental fact: namely, that fertility decisions are closely interrelated with decisions about union formation and union dissolution. LÄS MER
23. Timber Pile-Supported Embankments : Arching and Reinforcement
Sammanfattning : Reduced climate impact is a worldwide strive today. The foundation engineering industry is continuously searching for more sustainable solutions to reduce resource usage and pollutions directly or indirectly. One such solution is timber piling, as an alternative to the commonly used concrete and steel piles. LÄS MER
24. Computational Studies on Homogeneous Water Oxidation Catalysts
Sammanfattning : To combat the increasing energy demand and climate change, artificial photosynthesis is a promising approach to producing renewables by storing energy into chemicals and fuels. Water oxidation, responsible for offering electrons and protons to the reduction reactions, suffers from slow kinetics. LÄS MER
25. Genetic epidemiological approaches to the study of risk factors for cardiovascular diseases
Sammanfattning : Cardiovascular disease (CVD) is one of the most common causes of death in most developed countries. Genetic and environmental factors influence CVD and its risk factors in a complex fashion. Parallel to this, new statistical methods are being developed to make use of the new molecular genetic information. LÄS MER
