16. Environmental effects on pollen performance:potential consequences on gene flow
Abstract : This thesis illustrates the effects of environmental factors on pollen performance and its importance on gene flow. Pollen competitive ability between the wild and cultivated species of four genera belonging to Cucurbitaceae family was compared to evaluate the evolutionary potential for selection on pollen tube growth rate.

17. Interactions between neuronal nicotinic acetylcholine receptors, N-methyl-aspartate receptors and beta-amyloid in the brain of genetically modified mice : implications for Alheimer's disease
Abstract : The amyloid hypothesis is one of the leading theories in the search for the cause of Alzheimer's disease (AD) and is based on the theory that hyperproduction and accumulation of amyloid betapeptide (Abeta) in the brain triggers the disruption of neuronal and synaptic function, thereby ultimately leading to neurodegeneration and dementia. Some of the crucial questions are if Abeta has a neuronal function in the brain and how it interacts with the neurotransmitter system in AD. READ MORE

19. Walk this way : Verbs of motion in three Finno-Ugric languages
Abstract : The verbs of motion in North Khanty, North Saarni and Hungarian, three genetically related, but geographically, culturally and historically separated languages, are analysed from a synchronic and diachronic point of view. The study is based on material deriving from informants and written sources in each language. READ MORE

20. Starch structures and their usefulness in the production of packaging materials
Abstract : Environmental concerns about increasing industrial use of plastics and the associated waste are raising the demand for renewable sources to replace petroleum-based products, especially in the packaging sector. This thesis examined the relationship between molecular structures of starch and their material properties in coating materials for food packaging. READ MORE
