1. 16. Biofiltration of odorous gas emissions

   Författare :Anneli Andersson-Chan; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Sammanfattning : Biofiltration has shown its potential as an interesting treatment alternative for contaminated gas streams. Unlike conventional technologies, such as adsorption, scrubbers, and incineration, biofiltration offers effective pollution control at relatively low capital and operating costs, and without the generation of secondary pollution that may require subsequent treatment.

3. 17. Biological Pre-filtration and Surface Water Treatment - Microbial barrier function and removal of natural inorganic and organic compounds

   Författare :Gerald Heinicke; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Waterworks in Sweden that apply conventional chemical surface water treatment are facing a number of challenges, including changes in raw water quality and demands for improved particle removal. The chief objective of this work was to evaluate biological pre-filtration for typical Swedish surface water, regarding the removal of natural organic matter, particles, iron and manganese, and taste and odour compounds.

4. 18. Indoor Environmental Factors and its Associations with Asthma and Allergy Among Swedish Pre-School Children

   Författare :Linda Hägerhed Engman; Avdelningen för Byggnadsfysik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; epidemiology; Public health; children; validation; inspections; dampness; moisture problem; questionnaire; allergy; asthma; Folkhälsa; epidemiologi; health;

   Sammanfattning : It has been shown in a large number of scientific studies that living or working in a building with mould and moisture damage increases the risk for asthmatic and allergic symptoms. However, there is a need to establish more valid methods to obtain a more nuanced picture of the wide range of different types of moisture related problems. LÄS MER

5. 19. Oviposition site selection in mosquitoes : the role of conspecific larvae, heterospecific larvae and microbes

   Författare :Zaid Khan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : In mosquitoes, the evaluation and selection of oviposition sites is critical for the growth, development and survival of the offspring. Gravid mosquitoes rely primarily on olfactory cues emanating from breeding water containing, e.g., intra- and interspecific aquatic stages, as well as bacteria for this purpose. LÄS MER

7. 20. There is no easy answer : Factors affecting meat quality in lambs

   Författare :Elin Stenberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : This thesis examined the effects of production system, slaughter method, carcass handling procedures and storage method on the quality of meat from intact male lambs. Quality aspects of the meat assessed were carcass quality, meat quality indicators (measured on carcasses), technological meat quality (measured on meat samples) and sensory attributes. LÄS MER
