  2. 1. Molecular characterization and evolution of alpha-actinin : from protozoa to vertebrates

    Author : Ana Virel; Lars Backman; Kristina Djinovic-Carugo; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; alpha-actinin; evolution; spectrin repeat; intragene duplication; phylogenetic tree; spectrin superfamily; Biochemistry; Biokemi;

    Abstract : alpha-actinin is a ubiquitous protein found in most eukaryotic organisms. The ability to form dimers allows alpha-actinin to cross-link actin in different structures. In muscle cells alpha-actinin is found at the Z-disk of sarcomeres. READ MORE

  4. 2. Bacteria that escape predation : waterborne pathogens and their relatives

    Author : Karolina I. A. Eriksson; Agneta Andersson; Johanna Thelaus; Jon Ahlinder; David Sundell; Klaus Jürgens; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bacterial pathogens; protozoa; predation resistance; aquatic microbiology; climate change; opportunists; humification; iron; environmental science; miljövetenskap; mikrobiologi; Microbiology;

    Abstract : The hidden presence of opportunistic bacterial pathogens in the environment evokes concerns about emerging diseases, especially in the light of climate change. The co-evolution of bacteria and their predators (protozoa) has led to bacterial defence strategies of which some contribute to the ability of bacteria to cause disease. READ MORE

  5. 3. The aquatic microbial food web and occurence of predation-resistant and potentially pathogenic bacteria, such as Francisella tularensis

    Author : Johanna Thelaus; Agneta Andersson; Mats Forsman; Farooq Azam; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bacteria; protozoa; ecology; predation; nutrient-availability; microbial food web; model; predation-resistance; Francisella; reservoir; biofilm formation; Freshwater ecology; Limnisk ekologi;

    Abstract : All natural aquatic systems harbour a vast variety of microorganisms. In the aquatic microbial food web, the larger microorganisms (i.e. protozoa) feed on the smaller microorganisms (i. READ MORE

  6. 4. Inter and Intra-Assemblage Characterizations of Giardia intestinalis: from clinic to genome

    Author : Johan Ankarklev; Staffan Svärd; Johanna P. Daily; Uppsala universitet; []
    Keywords : Giardia; protozoa; parasite infection; diarrhea; genome sequencing; comparative genomics; genotyping; ASH; MLG; Infektionssjukdomar; Infectious Diseases; Molekylär medicin; Molecular Medicine; Mikrobiologi; Microbiology;

    Abstract : The protozoan parasite Giardia intestinalis (syn. G. lamblia, G. duodenalis) is one of the most common causes of diarrheal disease throughout the world, where an estimated 500 million people are infected annually. READ MORE

  7. 5. Modelling Aspects of Wastewater Treatment Processes

    Author : Ulf Jeppsson; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatiska system; control engineering; robotics; Automation; thickening; solids flux; simulation; secondary clarifier; protozoa; predators; parameter estimation; model reduction; model identifiability; mathematical modelling; clarification; biofilm; activated sludge; robotteknik; reglerteknik;

    Abstract : Wastewater treatment processes are inherently dynamic because of the large variations in the influent wastewater flow rate, concentration and composition. Moreover, these variations are to a large extent not possible to control. READ MORE
