  1. 1. Protein stabilization. Some methods and mechanisms

    Författare :Maria Andersson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sorbitol; protein stability; preferential exclusion; polyol; poly-NIPAAm; polymer; poly ethyleneimine ; polyelectrolyte; oxidation; NMR spectroscopy; lysozyme; lactate dehydrogenase; fluorescence; dynamic light scattering; complex; additive; circular dichroism; stabilization; trypsin; thermo-reversible polymer.; Biotechnology; Bioteknik;

    Sammanfattning : The effect of different additives on protein stability was studied, and the basis for stabilization was investigated at molecular level. The addition of sorbitol enhanced thermal stability of hen egg white lysozyme in aqueous solution. LÄS MER

  3. 2. Trophic interactions in the tundra: Impacts of large mammal herbivory on carbon processes and fungal communities

    Författare :Cole Brachmann; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Herbivory; Arctic; Fungi; Trace gas fluxes; Decomposition; Biogenic Volatile Organic Compounds; Mycorrhiza; Tundra; Reindeer;

    Sammanfattning : Plant productivity is generally increasing in the Arctic as a consequence of accelerated climate change. The change in plant communities may coincide with a loss of carbon from Arctic soils due to increased decomposition and respiration. LÄS MER

  4. 3. Effects of Natural Organic Matter on Herbicide Adsorption to Activated Carbon

    Författare :Åsa Edell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; natural organic matter; herbicide; adsorption isotherm; preloading; activated carbon; competitive interaction;

    Sammanfattning : The presence of pesticides in the aquatic environment represents a potential threat to water quality and human health. Increasingly stringent drinking water quality directives focus on the need for efficient pesticide removal processes. LÄS MER

  5. 4. Decoding the Structural Layer of Transcriptional Regulation : Computational Analyses of Chromatin and Chromosomal Aberrations

    Författare :Robin Andersson; Jan Komorowski; Jan Dumanski; Claes Wadelius; Anders Krogh; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chromatin; Nucleosome positioning; Histone modifications; Chromosomal aberrations; Transcriptional regulation; Array-CGH; Next generation sequencing; ChIP-chip; Bioinformatics; Bioinformatik; Bioinformatics; Bioinformatik;

    Sammanfattning : Gene activity is regulated at two separate layers. Through structural and chemical properties of DNA – the primary layer of encoding – local signatures may enable, or disable, the binding of proteins or complexes of them with regulatory potential to the DNA. LÄS MER

  7. 5. Atom Probe Tomography of Hard Nitride and Boride Thin Films

    Författare :David L. J. Engberg; Lars Hultman; Magnus Odén; Guido Schmitz; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Atom probe tomography APT ; Ceramics; Nitrides; Borides;

    Sammanfattning : Hard ceramic thin films, including TiSiN, ZrAlN, ZrB2, and ZrTaB2, with applications for wear-resistant coatings, have been studied using atom probe tomography and correlated with several other analytical techniques, including X-ray diffraction, electron microscopy, and elastic recoil detection analysis. Outstanding obstacles for quantitative atom probe tomography of ceramic thin films have been surmounted. LÄS MER
