  2. 1. Greenhouse gas emissions from Swedish milk production : towards climate-smart milk production

    Author : Maria Henriksson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES; AGRICULTURAL SCIENCES;

    Abstract : Greenhouse gas (GHG) emissions from food production represent 19-29% of global anthropogenic GHG and the dairy sector alone is estimated to contribute around 3%. This thesis assessed GHG estimates for milk production (i.e. milk carbon footprint (CF)) in a life cycle perspective. READ MORE

  4. 2. Human Rationality : Observing or Inferring Reality

    Author : Maria P. Henriksson; Mats Fredrikson; Henrik Olsson; Klaus Fiedler; Uppsala universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; supervised learning; unsupervised learning; adaptation; niche picking; prototypes; rules; exemplar memory.; Psychology; Psykologi;

    Abstract : This thesis investigates the boundary of human rationality and how psychological processes interact with underlying regularities in the environment and affect beliefs and achievement. Two common modes in everyday experiential learning, supervised and unsupervised learning were hypothesized to tap different ecological and epistemological approaches to human adaptation; the Brunswikian and the Gibsonian approach.

  5. 3. Cellular targets of Pseudomonas aeruginosa toxin Exoenzyme S

    Author : Maria Henriksson; Bengt Hallberg; Lars Rönnstrand; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Pseudomonas aeruginosa; ADP-ribosylation; GAP; Ras superfamily; NAD; ExoS; 14-3-3; Cellbiologi; Cell biology; Cellbiologi; molecular cell biology; molekylär cellbiologi;

    Abstract : Pseudomonas aeruginosa is an opportunistic pathogen that can cause life-threatening infections in immunocompromised patients. It uses a type III secretion dependent mechanism to translocate toxic effector proteins directly into the eukaryotic cell. READ MORE

  6. 4. Production and engineering of a xyloglucan endo-transglycosylase from Populus tremula x tremuloides

    Author : Maria Henriksson; Tuula Teeri; KTH; []
    Keywords : AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; xyloglucan endo-transglycosylase; retaining glycoside hydrolase; glycosynthase; Pichia pastoris; fed-batch fermentation; expanded-bed adsorption; Plant biotechnology; Växtbioteknik;

    Abstract : The aim of this work was to develop a production process for the enzyme xyloglucan endo-transglycosylase from Populus tremula x tremuloides (PttXET16-34). The natural transglycosylating activity of this enzyme has previously been employed in a XET-Technology. READ MORE

  7. 5. Composition of lignin in outer cell-wall layers

    Author : Maria Christiernin; Gunnar Henriksson; Gösta Brunow; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignin; thioacidolysis; primary wall; middle lamella; Populus balsamifera; Populus tremula L. x P. tremuloides Michx.; Picea abies; Picea glauca; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : The composition of lignin in the outer cell-wall layers of spruce and poplar has been studied and the data obtained have been compared with those of the mature reference wood in which the secondary cell wall predominates. Materials with exclusively or predominantly outer cell-wall layers were examined. READ MORE
