  1. 1. Purification Processes for Complex Biomacromolecules

    Author : Hans Blom; Helena Grennberg; Mats Lundgren; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Chromatography; enzymes; mucins; fractionation; plasmid DNA; analysis; clarification; process design; Chemistry with specialization in Surface Biotechnology; Kemi med inriktning mot ytbioteknik;

    Abstract : This thesis details various techniques and considerations for the purification of complex biomacromolecules. Initially an α-mannosidase from babaco fruit was purified using anion exchange-, lectin affinity- and size exclusion chromatography. READ MORE

  2. 2. Modelling Aspects of Wastewater Treatment Processes

    Author : Ulf Jeppsson; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

  3. 3. Nucleic Acids: Innovative Methods for Recovery, Clarification and Purification

    Author : Tiago Matos; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The importance of nucleic acids in pure form for preparative and analytical perspectives, have increased constantly, demanding the development of new and more efficient methods for their recovery and isolation. This thesis describes a series of different innovative methods for recovery and purification of these biomolecules. READ MORE

  4. 4. Cognition and communication in children/adolescents with cochlear implant

    Author : Tina Ibertsson; foniatri och audiologi Logopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; cochlear implant; working memory; conversational skills; request for clarification; reading; hearinr impairment; writing;

    Abstract : A cochlear implant (CI) is a device that provides individuals with severe to profound hearing impairment (SPHI) with auditory stimulation, which makes it possible for them to develop skills related to spoken communication. We have little knowledge about how hearing with a CI influences cognitive and communicative development and there is a need for development of methods for assessment. READ MORE
