1. 16. Zinc in folding and misfolding of SOD1 : Implications for ALS

   Författare :Lina Leinartaité; Mikael Oliveberg; Bengt-Harald Jonsson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein stability; protein misfolding; local unfolding; metal binding; energy landscape; protein disease; amyotrophic lateral sclerosis; Biochemistry; biokemi;

   Sammanfattning : Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease causing degeneration of upper and lower motor neurons. Most ALS cases are sporadic; only 6% are associated with mutations in Cu, Zn superoxide dismutase (SOD1). LÄS MER

3. 17. Construction of force measuring optical tweezers instrumentation and investigations of biophysical properties of bacterial adhesion organelles

   Författare :Magnus Andersson; Ove Axner; Lene Broeng Oddershede; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optical tweezers; biological physics; unfolding; Escherichia coli; force measurements; energy landscape; dynamic force spectroscopy; manipulation; polymers; pili; Physics; Fysik;

   Sammanfattning : Optical tweezers are a technique in which microscopic-sized particles, including living cells and bacteria, can be non-intrusively trapped with high accuracy solely using focused light. The technique has therefore become a powerful tool in the field of biophysics. LÄS MER

4. 18. A Study in RNA Bioinformatics : Identification, Prediction and Analysis

   Författare :Eva Freyhult; David Ardell; Robert Giegerich; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RNA; bioinformatics; secondary structure; structure prediction; dynamic programming; energy landscape; homology search; sequence logo; tRNA; Bioinformatics; Bioinformatik;

   Sammanfattning : Research in the last few decades has revealed the great capacity of the RNA molecule. RNA, which previously was assumed to play a main role only as an intermediate in the translation of genes to proteins, is today known to play many important roles in the cell in addition to that as a messenger RNA and transfer RNA, including the ability to catalyze reactions and gene regulations at various levels.

5. 19. Experimenting for change? : The politics of accomplishing environmental governance through smart energy pilot projects

   Författare :Fredrik Envall; Harald Rohracher; Dick Magnusson; Josefin Wangel; Matthew Cashmore; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; environmental governance; political rationality; experiment; smart energy; socio-technical perspective; knowledge politics; power relations; infrastructure.; miljöstyrning; politisk rationalitet; experiment; smarta nät; socio-tekniskt perspektiv; kunskapspolitik; maktrelationer; infrastruktur.;

   Sammanfattning : This thesis investigates how smart energy experimentation arranges environmental governance in Sweden, focusing on the politics of such processes, against the background of an escalating environmental and climate crisis that necessitates urgent energy transformation. Empirically the thesis includes case studies of pilot projects in Stockholm, Malmö, Västerås, and on Gotland, and analysis of the policy landscape, mainly through text analysis and interviews.

7. 20. Tailoring the magnetic order in mesoscopic spin systems

   Författare :Henry Stopfel; Vassilios Kapaklis; Hjörvarsson Björgvin; Unnar Arnalds; John Cumings; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; artificial spin ice; magnetic nano-structures; mesoscopic spin systems; mesospins; model systems; Shakti; Saint George; interaction modifier; engineering of energy-landscape; multiple energy-scales; Fysik; Physics;

   Sammanfattning : Mesoscopic spin systems can be designed and fabricated using modern nano-fabrication techniques. These systems can contain large numbers of patterned ferromagnetic elements, for which the shape will generally determine their effective mesospin dimensionality. LÄS MER
