1. 26. Anaerobic Digestion – Microbial Ecology, Improved Operational Design and Process Monitoring

   Författare :Marika Murto; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; monitoring; UASB; Biotechnology; Bioteknik; methanogens; fluorescence in situ hybridisation; FISH; co-digestion; biogas; biofilm; aqueous two phase system; anaerobic digestion; 16S rDNA; alkalinity;

   Sammanfattning : The implementation of anaerobic digestion is important in the concept of sustainable development, especially regarding the environmental benefits. Biogas is produced when organic matter is degraded by microorganisms under oxygen-free (anaerobic) conditions. LÄS MER

3. 27. Management of technology in the process industries:  Matching market and machine

   Författare :Peter Samuelsson; Pär Jönsson; Rob Boom; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process industries; manufacturing; innovation; configuration; strategizing; capability; configuration modelling; process industries; production system; physical modelling; AOD; converter geometry; injection; mixing times; electric arc furnace; EAF; post-combustion; high-impedance; network disturbances; operational results; Metallurgical process science; Metallurgisk processvetenskap;

   Sammanfattning : The process industries span multiple industrial sectors and constitute a substantial part of the entire manufacturing industry. Since companies belonging to this family of industries are often very asset intensive, their ability to respond to changes is often limited in the short term. LÄS MER

4. 28. Towards Climate Based Early Warning and Response Systems for Malaria

   Författare :Maquins Odhiambo Sewe; Joacim Rocklöv; Clas Ahlm; Yesim Tozan; Madeleine Thomson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Malaria; Mosquito; Lead time; Early Warnings; Forecasts; Economic Evaluation; Rainfall; KEMRI CDC HDSS; Kenya; Temperature; LST; NDVI; Climate; HDSS; GAM; GAMBOOST; DLNM; Remote Sensing; Net Benefit; Cost-Effectiveness; Boosting Regression; Weather; Public Health; Infectious Diseases; folkhälsa; Public health; Epidemiology; epidemiologi;

   Sammanfattning : Background: Great strides have been made in combating malaria, however, the indicators in sub Saharan Africa still do not show promise for elimination in the near future as malaria infections still result in high morbidity and mortality among children. The abundance of the malaria-transmitting mosquito vectors in these regions are driven by climate suitability. LÄS MER

5. 29. Integrated evaluation of resource efficiency and cost effectiveness in production systems

   Författare :Michael Lieder; Bengt Lindberg; Peter Almström; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resource; efficiency; effectiveness; production system; evaluation; small and medium-sized enterprises;

   Sammanfattning : Improved use of resources is of enormously high relevance and crucial for achieving as well as maintaining a sustainable condition. Especially industrial production has a superior responsibility in creating a long-term viable way of living. LÄS MER

7. 30. Green procurement of buildings: estimation of environmental impact and life-cycle cost

   Författare :Eva Sterner; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad; Construction Engineering and Management; Byggproduktion;

   Sammanfattning : This thesis focuses on environmental impact reduction and life-cycle cost estimations in building procurement. The aim for the work presented in this thesis is to contribute to the understanding of whether costs and environmental impact of a building can be integrated in a, from the users perspective, practical model applied for tender evaluation.
