1. 11. Ribosome and ribosomal RNA Structure : An experimental and computational analysis of expansion segments in eukaryotic ribosomal RNA

   Författare :Gunnar Alkemar; Odd Nygård; Anders Virtanen; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; eukaryotes; expansion segment; ribosomes; rRNA; secondary structure; structure of rRNA.; Cell biology; Cellbiologi; cellbiologi; Cellbiology;

   Sammanfattning : Ribosomes are large ribonucleoprotein complexes which incorporate amino acids into peptide chains during translational process in all types of living cells. The eukaryotic ribosome is larger compared to its prokaryotic counterpart. LÄS MER

3. 12. Magnetism and Structure in Metallic Multilayers

   Författare :Erik Holmström; Turek Ilja; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Magnetism; Interfaces; Structure; KKR-ASA; CPA; Quantum Well; Fysik; Physics; Fysik;

   Sammanfattning : The interplay between magnetism and structure has been studied in magnetic multilayers by electronic structure calculations based on density functional theory and analyzed in terms of models. The main ideas behind the Korringa-Kohn-Rostocker Green’s function method are described and the implementation of the coherent potential approximation is outlined. LÄS MER

4. 13. Structure-aided design of antiviral drugs : Application of the method on HIV-1 protease and SIV reverse transcriptase

   Författare :Hans Ola Andersson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; HIV; protease; SIV; reverse transcriptase; structure; inhibitor; drug design; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

   Sammanfattning : Many efforts have been made to control the AIDS epidemic. Extensive studies have been done on the biology, biochemistry, and structural biology of HIV in the search for antiviral drugs. The viral-encoded enzymes reverse transcriptase and protease have been main targets for drug design. LÄS MER

   Sammanfattning : This thesis deals with investment issues in connection to growth and expansion related decision processes in small and medium-sized manufacturing companies. It focuses primarily on the empirical knowledge about the structure of the companies’ investments, the processes involved, and the investment behavior in this type of company. LÄS MER

7. 15. Structure Determination and Prediction of Zeolites : A Combined Study by Electron Diffraction, Powder X-Ray Diffraction and Database Mining

   Författare :Peng Guo; Xiaodong Zou; Christine Kirschhock; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; zeolites; rotation electron diffraction; structure determination; structure prediction; strong reflections approach; Inorganic Chemistry; oorganisk kemi;

   Sammanfattning : Zeolites are crystalline microporous aluminosilicates with well-defined cavities or channels of molecular dimensions. They are widely used for applications such as gas adsorption, gas storage, ion exchange and catalysis. The size of the pore opening allows zeolites to be categorized into small, medium, large and extra-large pore zeolites. LÄS MER
