  1. 21. SECONDARY FLUIDS USED IN INDIRECT REFRIGERATION SYSTEMS IN SWEDEN

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Patrick Javier Salom Munoz; [2015]
    Keywords : Secondary fluids; ground source heat pumps; indirect refrigeration system; regulations; Swedish market;

    Abstract : Interest in indirect (secondary) refrigeration systems has grown since the discovery of the negative effect of environmentally hazardous refrigerants and leakage problems from direct expansion systems. Among the positive effects of indirect systems are: decreased quantities of primary refrigerant, factory built units and confinement of refrigerant to the machine room. READ MORE

  3. 22. Polymerization of Zwitterionic Sulphobetaine Methacrylate and Modification of Contact Lens Substrate

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Tobias Ingverud; [2015]
    Keywords : Zwitterionic; Sulphobetaine; RAFT; ATRP; End-group-modification; Grafting-to; Contact lens; zwitterjonisk; RAFT; ATRP; ändgrupps modifiering; ympning-till; kontakt;

    Abstract : In this study, the zwitterionic monomer [2-(methacryloyloxy)ethyl] dimethyl-(3-sulfopropyl) ammonium hydroxide (SBMA) was polymerized in a controlled manner by reversible addition-fragmentation chain transfer (RAFT) polymerization. The SBMA was also polymerized by atom transfer radical polymerization (ATRP) but in a less controlled manner why ATRP was discarded for further use in the study. READ MORE

  4. 23. Optimization of a PEGylation process

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Fredrik Tegnér; [2015]
    Keywords : SERC reactor; Simulation; PEGylation; Optimization; chemical engineering; kemiteknik; Technology and Engineering;

    Abstract : The PEGylation process is a covalent attachment between a protein (the pharmaceutical) and poly ethylene glycol (PEG) and since the beginning in 1977 PEGylation processes have been used to improve pharmaceuticals. PEGylation of a pharmaceutical achieves improved properties like greater solubility in water, longer residence time in vivo and extended shelf life. READ MORE

  5. 24. Toxiska ämnen för hund : råttgift och etylenglykol

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Ellinor Runesvärd; [2015]
    Keywords : koagulation; brodifakum; kylarvätska; toxiska metaboliter; njurtoxicitet; förgiftning; coagulation; brodifacoum; antifreeze; toxic metabolites; nephrotoxicitiy; intoxication;

    Abstract : Denna litteraturstudie behandlar förgiftningar hos hund med begränsning till förgiftning orsakat av etylenglykol och råttgift. Vilket av dessa ämnen som är farligast och hur stor risken är att en hund får i sig dem är två frågor som kommer att undersökas. READ MORE

  6. 25. Lamination of Organic Solar Modules

    University essay from Biomolekylär och Organisk Elektronik; Tekniska högskolan

    Author : Sofie Kalldin; [2014]
    Keywords : Organic solar modules; Lamination; PEDOT:PSS; Ethylene Glycol EG ; Diethylene Glycol DEG ; Polyethylene Glycol PEG ; Roll to roll process R2R ;

    Abstract : As the Worlds energy demand is increasing we need more of our energy to be generated from resources that affect the climate as little as possible. Solar power could be the solution if there were solar panels with a less energy demanding production than the established silicon based solar modules. READ MORE
