2. 1. Change of toxicity during secondary treatment of industrial sludge containing nitroaromatics

   Author : Lillemor Gustavsson; Magnus Engwall; Anna Schnürer; Ulrika Welander; Mårten Jönsson; Bo Mattiasson; Göran Dave; Örebro universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic; aerobic; AhR agonists; CALUX; constructed wetlands; Danio rerio; embryotoxicity; genotoxicity; nitroaromatics; sludge; Environmental engineering; Miljöteknik; Enviromental Science; Miljövetenskap;

   Abstract : Wastewater treatment plants in Sweden are facing a great challenge due to the prohibition of depositing organic waste which gained legal force in January 2005. Biological and commercial available alternatives to disposal are composting and anaerobic digestion. READ MORE

4. 2. Upflow anaerobic sludge blanket reactor : modelling

   Author : Raul Rodriguez; Luis Moreno; Olle Wahlberg; Gunno Renman; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; wastewater; anaerobic treatment; modelling; UASB reactor.; Chemistry; Kemi;

   Abstract : Anaerobic treatment is widely used around the world as a biological stage in both domestic and industrial wastewater-treatment plants. The two principal advantages of anaerobic over aerobic treatment are the production of biogas, which can be used as fuel, and the lower rate of biomass production, which results in lower maintenance costs for the plant.

5. 3. Structural studies on aerobic and anaerobic respiratory complexes

   Author : Susanna Törnroth; Lars Hederstedt; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

   Abstract : All respiratory pathways, whether aerobic or anaerobic, are based on formation of an electrochemical proton gradient called proton motive force (pmf) that drives ATP formation. Membrane-bound respiratory complexes translocate protons across the membrane from a region of low [H+] and negative electrical potential to a region of high [H+] and positive electrical potential.

6. 4. Firefighters' physical work capacity

   Author : Ann-Sofie Lindberg; Christer Malm; Juha Oksa; Desiree Gavhed; Peter Krustrup; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical demands; performance; work capacity; aerobic fitness; anaerobic fitness; muscle strength; muscle endurance; balance; ergonomics; physical testing; SIMCA;

   Abstract : The overall aim of this thesis was to identify valid, simple, and inexpensive physical tests that can be used for evaluation of firefighters’ physical work capacity. Paper I included fulltime- and part-time firefighters (n = 193), aged 20-60 years. READ MORE

7. 5. Exploring Anaerobic Bacteria for Industrial Biotechnology - Diversity Studies, Screening and Biorefinery Applications

   Author : Rosa Aragao; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic bacteria; industrial biotechnology; biorefinery; microbial diversity; single cell entrapment; llama rumen;

   Abstract : Depletion of easily accessible fossil energy resources, threat of climate change and political priority to achieve energy self-sufficiency and sustainable solutions prioritize a conscious and smart use of renewable resources to generate a bio-based economy. Bio-based compounds can replace chemicals and fuels that are now mainly produced from crude oil. READ MORE
