1. Oral cancer with special reference to virus detection and quantitative gene expression
Sammanfattning : Background. Head and neck cancers (HNC) are among the most common malignancies worldwide, and about 90–92% of oral neoplasias are oral squamous cell carcinomas (OSCC). Alcohol and tobacco consumption have been recognized as the main risk factors for OSCC development. LÄS MER
2. External Mycelia of Mycorrhizal Fungi - responses to elevated N in forest ecosystems
Sammanfattning : Most plants live in symbiosis with mycorrhizal fungi. Mycorrhizal roots constitute the interface between the plant and the soil, and almost every fine root of forest trees in nitrogen-limited boreal and temperate forests is colonised by ectomycorrhizal (EM) fungi. LÄS MER
3. Mineralisation rates of natural organic matter in surface sediments affected by physical forces
Sammanfattning : Nedbrytning av organiskt material är en nyckelfaktor som påverkar omvandlingar av de många grundämnen som utgör eller är associerade till just organiskt material. En stor del av nedbrytningen av akvatiskt organiskt material (OM) sker i gränsskiktet mellan sediment och vatten. LÄS MER
4. Model Studies of Surface Waves and Sediment Resuspension in the Baltic Sea
Sammanfattning : Wave heights and periods of surface waves in the Baltic Sea have been modelled for a two-year period (1999-2000) with the wave model Hypas on an 11x11-km grid scale. There is a clear seasonal variation with higher waves during winter and lower during summer. LÄS MER
