  1. 1. Redox models in chemistry  A depiction of the conceptions held by secondary school students of redox reactions

    University dissertation from Umeå : Kemiska institutionen. Umeå universitet

    Author : Lise-Lotte Österlund; Umeå universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; science education; redox reaction; model; inorganic chemistry; organic chemistry; biochemistry; students conceptions; textbook; NATURAL SCIENCES Chemistry Other chemistry; NATURVETENSKAP Kemi Övrig kemi; didactics of chemistry; kemididaktik;

    Abstract : According to previous research, students show difficulties in learning redox reactions. By the historical development different redox models exist to explain redox reactions, the oxygen model, the hydrogen model, the electron model and the oxidation number model. READ MORE

  2. 2. Wastewater treatment and biomass generation by Nordic microalgae growth in subarctic climate and microbial interactions

    University dissertation from Umeå : Umeå University

    Author : Lorenza Ferro; Umeå universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microalgae; Wastewater; Nitrogen; Phosphate; Biomass; Lipids; Subarctic Climate; Light; Temperature; Bacteria; Photoautotrophy; Heterotrophy; Mixotrophy; HRAP; Metabarcoding; Microbial Communities; Alpha-diversity; Environmental Factors; Biochemistry; biokemi; mikrobiologi; Microbiology;

    Abstract : Nordic native microalgal strains were isolated, genetically classified and tested for their ability to grow in municipal wastewater. Eight of the isolated strains could efficiently remove nitrogen and phosphate in less than two weeks. Two of these strains, Coelastrella sp. READ MORE

  3. 3. Get in tune chloroplast and nucleus harmony

    University dissertation from Umeå : Umeå University

    Author : Dmitry Kremnev; Umeå universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplast; development; gene expression;

    Abstract : Photosynthetic eukaryots emerged as a result of several billion years of evolution between proeukaryotic cell and ancestral cyanobacteria that formed modern chloroplasts. The symbiotic relationship led to significant rearrangements in the genomes of the plastid and the nucleus: as many as 90 % of all the plastid genes were transferred to the nucleus. READ MORE

  4. 4. Physiology of Saccharomyces cerevisiae Producing Recombinant Insulin in Continuous Culture

    University dissertation from Umeå : Umeå University

    Author : Ali Kazemi Seresht; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; unfolded protein response; Keywords: heterologous protein production; prolonged chemostat; transcriptome; insulin analogue precursor; metabolic adaptation; URA3d; plasmid copy number; promoter truncation; high cell density cultivation; TPI1;

    Abstract : The yeast Saccharomyces cerevisiae has widely been used as a host for the production of heterologous proteins. High-level production of heterologous proteins is likely to impose a metabolic burden on the host cell and can thus affect various aspects of cellular physiology. READ MORE

  5. 5. Protein and lipid interactions within the respiratory chain Studies using membrane-mimetic systems

    University dissertation from Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Author : Tobias Nilsson; Stockholms universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cytochrome c oxidase; ATP synthase; Bioenergetics; membrane-mimetics; Rcf1; liposomes; oxidative phosphorylation; lipids; protein-protein interactions; biokemi; Biochemistry;

    Abstract : Energy conversion from nutrients to ATP is a vital process in cells. The process, called oxidative phosphorylation (OXPHOS) is performed by a combination of membrane-bound proteins. These proteins have been studied in great detail in the past, however much is still unknown about how they interact with each other. READ MORE
