21. Factors influencing emission fluxes and bacterial enrichment in sea spray aerosols : Insights from laboratory and field studies
Sammanfattning : Sea spray aerosol (SSA) is one of the major natural aerosol sources and is produced when wave breaking entrains air into ocean surface water, which subsequently breaks up into bubbles. These bubbles rise to the surface and can scavenge biogenic material. LÄS MER
22. Investigation of immune cell-derived factors as potential biomarkers in patients with colorectal cancer
Sammanfattning : Colorectal cancer (CRC) is the third most common cancer and the second leading cause of cancer related death. It is a heterogeneous disease involving multiple molecular pathways that result in differing phenotypes. Individual variability in CRC susceptibility is influenced by genetic variation, such as single nucleotide polymorphisms (SNPs). LÄS MER
23. Molecular and serological tools for clinical diagnostics of Lyme borreliosis - can the laboratory analysis be improved?
Sammanfattning : Lyme borreliosis (LB) is caused by spirochetes within the Borrelia burgdorferi sensu lato complex and is the most common tick-transmitted disease in the northern hemisphere. The transmission of the spirochetes to humans in Europe is done by the Ixodes ricinus ticks, which can also transmit the relapsing fever species Borrelia miyamotoi. LÄS MER
24. Biological Laboratory X-Ray Microscopy
Sammanfattning : Soft x-ray microscopy in the water window (? ≈ 2.3 − 4.3 nm) is a powerful technique for high-resolution biological imaging. The strong natural contrast between carbon-based structures and water allows visualization of hydrated and unstained samples, while providing enough transmission through up to ∼ 10 μm of organic matter.

25. Learning Physics Through Communication During Laboratory Work : An empirical study at upper secondary school
Sammanfattning : Laboratory work as a teaching and learning method is given prominence in the Swedish physics curriculum for upper secondary school. It is emphasised that students should be given opportunities to develop the ability to search for answers to questions, plan, conduct, interpret and present results. LÄS MER
