  1. 21. E-Government and Value Creation in the Context of a Least Developed Country : A perspective on public value and information infrastructure

    Författare :Jean Damascene Twizeyimana; Annika Andersson; Åke Grönlund; Hannu Larsson; Karin Axelsson; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; E-government; value creation; public value; information infrastructure; LDCs; installed-base; Rwanda;

    Sammanfattning : This thesis is in the field of information systems (IS), more specifically about IS impact. This thesis uses literature review and interpretive case study methods to investigate the phenomenon of value creation through e-government.The research was carried out from 2014 to 2019. LÄS MER

  3. 22. Bench-Scale Production of Heterologous Proteins from Extremophiles- Escherichia coli and Pichia pastoris based expression systems

    Författare :Santosh Ramchuran; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Glycoside hydrolase; Heterologous protein; High cell density cultivation Expression systems; Bioteknik; Biotechnology; Fed-batch;

    Sammanfattning : Over the past few years considerable research attention has been assigned to extremophiles as sources of extremozymes due to their applicability in industrial processes, and the development of eco-friendly technologies. The establishment of efficient production strategies for heterologous proteins is an empirical process requiring broad background knowledge on available expression systems together with their major advantages and shortcomings.

  4. 23. Design and assessment of legume-supported cropping systems

    Författare :Moritz Reckling; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Legumes provide high quality protein for food and feed as well as other ecosystem services, but it is still challenging to use them to meet the growing global demand for protein, partly because European farmers consider their cultivation unprofitable and risky. This thesis aims to design legume-supported cropping systems and assess their environmental and economic impacts along with their production risks in European agriculture. LÄS MER

  5. 24. Life Cycle Assessment (LCA) of Food Products and Production Systems

    Författare :Karin Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Life Cycle Assessment (LCA), which is a method for analysis and assessment of the environmental impact caused by product systems, and its application to food products and production systems have been studied. For foods, the complete product system includes: production of inputs to agriculture, agricultural production, industrial refining, storage and distribution, packaging, the household phase and waste management.

  7. 25. Agroforestry systems with trees for biomass production in western Kenya

    Författare :Hans Sjögren; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Low agricultural production and a decline in fuelwood resources are serious constraints for subsistence smallholder farmers in western Kenya in the sub-Saharan African region. Furthermore, low soil fertility and general environmental degradation has contributed to the build-up of the parasitic weed Striga hermonthica. LÄS MER
