  1. 21. Factors influencing emission fluxes and bacterial enrichment in sea spray aerosols : Insights from laboratory and field studies

    Författare :Julika Zinke; Matthew E. Salter; Paul Zieger; Rachel A. Foster; E. Douglas Nilsson; Patricia K. Quinn; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sea spray aerosols; eddy covariance fluxes; air-sea-exchange; bacteria; primary biological airborne particles; laboratory studies; field studies; Baltic Sea; North-Eastern Atlantic; Environmental Sciences; miljövetenskap;

    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

  3. 22. Investigation of immune cell-derived factors as potential biomarkers in patients with colorectal cancer

    Författare :Levar Shamoun; Dick Wågsäter; Jan Dimberg; Kalle Landerholm; Blanka Kolodziej; Richard Palmqvist; Uppsala universitet; []

    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).

  4. 23. Molecular and serological tools for clinical diagnostics of Lyme borreliosis - can the laboratory analysis be improved?

    Författare :Malin Lager; Anna J. Henningsson; Peter Wilhelmsson; Per-Eric Lindgren; Andreas Matussek; Fredrik Elgh; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    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

  5. 24. Biological Laboratory X-Ray Microscopy

    Författare :Mikael Kördel; Hans Hertz; Ulrich Vogt; Jonas A. Sellberg; Rajmund Mokso; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; x-ray microscopy; laboratory x-ray microscopy; water window; biological; cell imaging; virus; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik; Optik och fotonik; Optics and Photonics;

    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.

  7. 25. Learning Physics Through Communication During Laboratory Work : An empirical study at upper secondary school

    Författare :Jan Andersson; Margareta Enghag; Carl Angell; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Physics education; Laboratory Work; Inquiry; Communication; Discourse Analysis; Physics; Fysik;

    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
