  2. 21. Prokaryotic Arsenic Resistance - Studies in Bacillus subtilis

    Author : Emil Aaltonen; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ArsB; Bacillus subtilis; arsenic resistance; arsenate reduction; arsenite transport; gene regulation; arsenate; ArsR; arsenite; transmembrane topology; Acr3; ArsK;

    Abstract : Arsenic is a toxic metalloid which is found all over the globe. Due to its toxicity and wide abundance, all living organisms have evolved intrinsic arsenic resistance systems. In this study, three proteins that provide arsenic resistance in the Gram-positive bacterium Bacillus subtilis have been investigated. READ MORE

  4. 22. Measuring distal airspace dimensions with nanoparticles. Initial development of a diagnostic method

    Author : H Laura Aaltonen; Malmö Diagnostisk radiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nanoparticles; COPD; AiDA; biomarker;

    Abstract : Chronic obstructive pulmonary disease (COPD) consists of emphysema and bronchial disease. The pulmonary function tests currently used to diagnose COPD have poor sensitivity for early disease. This may delay diagnosis and lead to a poorer prognosis compared to establishing the diagnosis at an earlier stage. READ MORE

  5. 23. Ground Monitoring using Resistivity Measurements in Glaciated Terrains

    Author : Jaana Aaltonen; KTH; []
    Keywords : Resistivity; DIrect Current; Monitoring; Groundwater; Contaminant; Tracer Test; Geophysics;

    Abstract : The most common method of monitoring and mapping groundwatercontaminants is to extract and analyse a number of groundwatersamples from wells in the investigation area. However, thereare a number of limitations with this type of point-wiseinvestigation, as it is hard to acquire an adequate picture ofa heterogeneous and anisotropic subsurface using a fewpoints.

  7. 25. Mating system evolution and self-incompatibility in the wild plant species Brassica cretica

    Author : Kristina Aaltonen; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mating system; Brassicaceae; Brassica cretica; recombination; frequency-dependent selection; evolution; population structure; segregation distortion; SCR; self-incompatibility; SRK;

    Abstract : Compared to animals like ourselves, plants have a very flexible sexual life. Most plants are, for example, hermaphrodites with the potential capacity for reproduction by self-fertilization (or selfing). READ MORE
