  2. 1. Studies on the Non-covalent Interactions (Stereoelectronics, Stacking and Hydrogen Bonding) in the Self-assembly of DNA and RNA

    Author : Parag Acharya; Jyoti Chattopadhyaya; Frank Seela; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bioorganic chemistry; nucleic acids; NMR; Stereoelectronic effects; Hydrogen Bonding; Stacking; Bioorganisk kemi; Bioorganic chemistry; Bioorganisk kemi;

    Abstract : This thesis is based on ten publications (Papers I-X). The phosphodiester backbone makes DNA or RNA to behave as polyelectrolyte, the pentose sugar gives the flexibility, and the aglycones promote the self-assembly or the ligand-binding process. READ MORE

  4. 2. Energy Storage Systems in Electrical Distribution Grids : Analysis and implementations of use cases for service stacking

    Author : Johannes Hjalmarsson; Cecilia Boström; Karin Thomas; Louise Ödlund; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ancillary services; congestion management; distribution grids; energy storage systems; scheduling optimization; service stacking.;

    Abstract : This Ph.D. thesis investigates the possibility of using energy storage systems for multiple services by implementing service stacking, with special emphasis on congestion management in distribution grids. READ MORE

  5. 3. Stacking Faults in Silicon Carbide

    Author : Hisaomi Iwata; Friedhelm Bechstedt; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This PhD thesis comprises a series of theoretical studies on various stacking faults in silicon carbide polytypes, based on first-principles density functional modelling, which lead to a detailed insight into general electronic properties of stacking disordered system. This work is largely motivated by the discovery in 1999 by ABB Corporate Research of the electronic degradation phenomenon in 4H-SiC p-i-n diodes. READ MORE

  6. 4. Some Aspects of Physicochemical Properties of DNA and RNA

    Author : Sandipta Acharya; Jyoti Chattopadhyaya; Piet Herdewijn; Uppsala universitet; []
    Keywords : Bioorganic chemistry; nucleic acids; hydrogen-bonding; stacking; single-stranded; NMR; molecular dynamics; Bioorganisk kemi;

    Abstract : This thesis is based on nine research publications (I – IX) on structure and reactivity of RNA vis-à-vis DNA. The DNA and RNA are made of flexible pentose sugar units, polyelectrolytic phosphodiester backbone, and heterocyclic nucleobases. DNA stores our genetic code, whereas RNA is involved both in protein biosynthesis and catalysis. READ MORE

  7. 5. Bioenergy from Swedish forests : A Study of extraction methods, quality and effects for forest owners

    Author : Daniel Nilsson; Johan Bergh; Peter Lerman; Gudmund Vollbrecht; Nasko Terziew; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; logging residues; forest fuels; moisture content; needles; nutrients; moisture content measurements; Norway spruce; dry-stacking; fresh-stacking; Forestry and Wood Technology; Skog och träteknik;

    Abstract : The forest constitutes a very important element of renewable natural resources and makes a significant contribution to the Swedish bioeconomy. Biofuels are Sweden’s largest source of energy; of all the energy we use, 32% comes from biofuels, and of this approximately 85% comes from the forest and the forestry sector. READ MORE
