  2. 2. Computer Science Project Courses Contrasting Students’ Experiences with Teachers’ Expectations

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Mattias Wiggberg; Uppsala universitet.; Uppsala universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computer science education; computer science student projects; computer science projects; computer science education research; phenomenography; learning; higher education; communities of practice; capstone projects; constructivism; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap; Datavetenskap med inriktning mot datavetenskapens didaktik; Computer Science with specialization in Computer Science Education Research;

    Sammanfattning : Including small or large project courses is widely recognized as important in preparing computer science students for a professional career. Typical examples are the capstone courses, which often are seen as the jewel in the crown since this is where students will bring their previous knowledge and skills together to show mastery of their craft.

  3. 3. Chlorine Cycling in Terrestrial Environments

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Malin Montelius; Linköpings universitet.; Linköpings universitet.; [2016]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chloride; organic chlorine; chlorination; dechlorination; 36Cl; risk assessment modelling; Klorid; organiskt klor; klorering; deklorering; klor-36; riskmodellering;

    Sammanfattning : Chlorinated organic compounds (Clorg) are produced naturally in soil. Formation and degradation of Clorg affect the chlorine (Cl) cycling in terrestrial environments and chlorine can be retained or released from soil. LÄS MER

  4. 4. Soil nitrogen fluxes and root uptake in the boreal forest

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Olusegun Ayodeji Oyewole; Sveriges lantbruksuniversitet.; [2015]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Nitrogen (N) is essential for growth and net primary production of plants. However, N acquisition by plants is influenced by movement of soil N compounds from bulk soil to plant roots and uptake of N by roots. This thesis is aimed at deepening our knowledge on these key processes involved in plant N acquisition in the N-limited boreal forest. LÄS MER

  5. 5. Importance of tannins for responses of aspen to anthropogenic nitrogen enrichment

    Detta är en avhandling från Umeå : Umeå University

    Författare :Franziska Bandau; Umeå universitet.; Umeå universitet.; [2016]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; aspen; foliar condensed tannins; genetic variability; anthropogenic nitrogen enrichment; plant growth; plant defense; litter decomposition; Populus tremula; asp; kondenserade tanniner; genetisk variabilitet; antropogent kväve; tillväxt; växtförsvar; förna nedbrytning; Populus tremula; Environmental Science; miljövetenskap; ekologisk botanik; Ecological Botany; Entomology; entomologi; Physiological Botany; fysiologisk botanik; Population Biology; populationsbiologi;

    Sammanfattning : Boreal forests are often strongly nitrogen (N) limited. However, human activities are leading to increased N inputs into these ecosystems, through atmospheric N deposition and forest fertilization. LÄS MER
