1. Structure of small RNA phages
Sammanfattning : Small RNA phages belonging to the family Leviviridae are among the simplest known viruses. They have been used extensively as models for studies of various problems in molecular biology, including protein-RNA interactions, repression of translation, virus assembly and virus evolution.

2. Structural Studies of Bacteriophage PRR1 and HIV-1 protease
Sammanfattning : Viruses are a diverse genera of organisms adapted to thrive in many different hosts from prokaryotic to eukaryotic.We present here the structure of bacteriophage PRR1 virus-like particle (VLP), belonging to Leviviridae family. Our structure reveals calcium ions in the VLP. LÄS MER
3. Structure of Small Icosahedral Viruses
Sammanfattning : This thesis presents structural studies on the plant virus Ryegrass mottle virus (RGMoV), the bacteriophage φCb5, and the icosahedral particles and octahedral crystal assembly of a bacteriophage MS2 coat protein mutant. In contrast to other sobemoviruses, the RGMoV coat protein is missing several residues in two of the loop regions important for capsid assembly. LÄS MER
4. Benzene-char conversion and particle-vapor characterization in biomass gasification
Sammanfattning : Biomass is increasingly attracting attention as an alternative to fossil fuels. Gasification permits the thermochemical conversion of biomass into a product gas rich in carbon monoxide and hydrogen. The product gas can be further processed to generate heat, electricity, synthesis gas, chemicals, and biofuels. LÄS MER
5. Study of the activity of catalysts for the production of high quality biomass gasification gas : with emphasis on Ni-substituted Ba-hexaaluminates
Sammanfattning : The fossil hydrocarbons are not inexhaustible, and their use is not without impact in our need of energy, fuels and hydrocarbons as building blocks for organic materials. The quest for renewable, environmentally more friendly technologies are in need and woody biomass is a promising candidate, well provided in the boreal parts of the world. LÄS MER
