2. 1. Study of gas fuel jet burning in low oxygen content and high temperature oxidizer

   Author : Magnus Mörtberg; Wlodek Blasiak; David G. Lilley; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; combustion; entrainment; jet in crossflow; PIV; ICCD; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Abstract : During the past decade, new advanced combustion systems that share the same basic concept of using a substantially diluted and high-temperature oxidizer in the reaction volume have gained a great deal of interest regarding their application in industrial and power systems. These novel combustion technologies have proved to offer significant benefits compared to traditional combustion techniques. READ MORE

4. 2. SOD1 misfolding and aggregation in ALS : in the light of conformation-specific antibodies

   Author : Manuela Lehmann; Jonathan D. Gilthorpe; Stefan L. Marklund; Thomas Brännström; Ulrika Nordström; Elizabeth Fisher; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ALS; antibodies; SOD1; disordered SOD1; patient-derived models; low oxygen tension; Immunotherapy;

   Abstract : Mutations in the superoxide dismutase 1 (SOD1) gene are linked to the progressive neurodegenerative disease amyotrophic lateral sclerosis (ALS). ALS-associated mutations affect the stability of the SOD1 protein and promote its unfolding. As a consequence, disordered SOD1 species can misfold and accumulate into insoluble aggregates. READ MORE

5. 3. High Temperature Corrosion of Stainless Steels in Low Oxygen Activity Environments -The effect of H2 and H2O

   Author : Hamed Hoseini Hooshyar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pre-oxidation; chromia former; H2O; High Temperature Corrosion; alumina former; H2;

   Abstract : Gasification of biomass and waste is promising for reducing the use of fossil fuels. While the operation conditions of superheaters and gas coolers in the gasifier are restricted by gas-side corrosion, scientific investigations are very scarce in this field. READ MORE

6. 4. Using patient-derived cell models to investigate the role of misfolded SOD1 in ALS

   Author : Elin Forsgren; Jonathan Gilthorpe; Stefan Marklund; Peter Andersen; Thomas Brännström; Ulrika Nordström; Séverine Boillée; Umeå universitet; []
   Keywords : ALS; SOD1; patient-derived models; induced pluripotent stem cells; motor neurons; astrocytes; 20S proteasome low oxygen tension; misfolded SOD1; Neurology; neurologi;

   Abstract : Protein misfolding and aggregation underlie several neurodegenerative proteinopathies including amyotrophic lateral sclerosis (ALS). Superoxide dismutase 1 (SOD1) was the first gene found to be associated with familial ALS. READ MORE

7. 5. Regulation and role of epiphytic nitrification and denitrification in macrophyte-dominated systems

   Author : Peder Eriksson; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; marine biology; Hydrobiology; submerged; emergent; epiphyton; bacteria; nitrate; wetland; nitrogen; littoral; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

   Abstract : This thesis examines mechanisms regulating bacterial nitrification and denitrification in attached microbial communities on surfaces of aquatic macrophytes. It also evaluates the role of epiphytic nitrification and denitrification for the nitrogen turnover in macrophyte-dominated nutrient-rich freshwaters. READ MORE
