  2. 11. Extent and limitations of functional redundancy among bacterial communities towards dissolved organic matter

    Author : Martin Andersson; Eva Lindström; Stuart Jones; Uppsala universitet; []
    Keywords : Dissolved organic matter; BCC; biodiversity; functional redundancy; Mikrobiologi; Microbiology;

    Abstract : One of the key processes in the carbon cycle on our planet is the degradation of dissolved organic matter (DOM) in aquatic environments. The use of organic matter by bacteria links energy from DOM to higher trophic levels of the ecosystem when bacteria are consumed by other organisms. This is referred to as the microbial loop.

  4. 12. Making a difference : project result improvement in organizations

    Author : Martin Andersson; Center for Information Management (SE); []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis is about how project results can be improved in organizations. The focus is on project-intensive organizations, where a central part of the operative work is carried out in project form. This is common in product development, software development, business development, industrial construction, etc. READ MORE

  5. 13. Olfaction in the spruce bark beetle, Ips typographus : receptor, neuron and habitat

    Author : Martin Andersson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The bark beetle Ips typographus regularly kills spruce trees in the Palearctic. Spruces are colonized by means of attraction to an aggregation pheromone. Attraction is modulated by anti-attractive volatiles (NHV) from non-host plants. In this thesis, olfaction in I. READ MORE

  6. 14. Process analytical methods for monitoring of the film coating on pharmaceutical pellets and tablets using NIR spectrometry and image analysis

    Author : Martin Andersson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PLS; PCA; PAC; NIR; chemometrics; moving samples; information depth; release rate; image analysis; near infrared; process analytical chemistry; thickness; coating; film; tablets; Pellets; granules; Analytical chemistry; Analytisk kemi;

    Abstract : Pharmaceutical tablets and pellets are often covered with a coating. There is a need for methods that enable monitoring of the growth of such films during processing. Such analyses can be performed using process analytical chemical methods based on near infrared (NIR) diffuse reflectance spectrometry. It provides with analyses that take only ca. READ MORE

  7. 15. SOFC Modeling Considering Mass and Heat Transfer, Fluid Flow with Internal Reforming Reactions

    Author : Martin Andersson; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; COMSOL Multiphysics; Modeling; Catalyst; CFD; Transport phenomena; Internal reforming reaction; IT-SOFC; LTNE;

    Abstract : Fuel cells are promising for future energy systems, since they are energy efficient and, when hydrogen is used as fuel, there are no emissions of greenhouse gases. Fuel cells have during recent years various improvements, however the technology is still in the early phases of development. READ MORE
