16. Characterization of Antigenic Properties of Two Immunogenic Proteins of Streptococcus pneumoniae
University essay from Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologiAbstract : The bacterium Streptococcus pneumoniae (pneumococcus), is considered to be a leading cause of morbidity and mortality globally, particularly in infants and the elderly. It is one of the most frequent causes of respiratory tract infections, which sporadically have the potential to develop into serious invasive symptoms including sepsis and meningitis. READ MORE

17. Ligand-stimulated cleavage of PDGFR-beta
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : Platelet-derived growth factor receptors (α and β) are included in the family of receptor tyrosine kinases (RTKs). The dimeric PDGF ligands bind to the PDGF receptors and this results in receptor dimerization, autophosphorylation, and thus activation. The autophosphorylated receptor dimer activates numerous signaling pathways. READ MORE

19. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells
University essay from Lunds universitet/Centrum för analys och syntesAbstract : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

20. Investigation of flux dependence on viscosity in ultrafiltration
University essay from Lunds universitet/Kemiteknik (CI)Abstract : This project aims to compare the effect of viscosity on flux for high viscosity liquids. The performance of two different viscous solutions was studied in a plate-and-frame membrane module. READ MORE
