  1. 11. Human Use of Land and Organic Materials: Modeling the Turnover of Biomass in the Global Food System

    Författare :Stefan Wirsenius; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industrial ecology; diet; efficiency; feed; biomass; livestock; physical model; global food system;

    Sammanfattning : This thesis is directed towards the issue of the long-term demand and supply of biomass for food, energy and materials. In the coming decades, the global requirements for biomass for such services are likely to increase substantially. LÄS MER

  3. 12. Integration of logistics network in local food supply chains

    Författare :Techane Bosona; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The demand for locally produced food is increasing as global food supply system has considerably affected the confidence of consumers by increasing tonne-kilometres, food safety risk, environmental impact, and disconnecting local food producers and consumers. However, local food suppliers are not in the position to compete with large scale food supply systems due to high logistics costs. LÄS MER

  4. 13. Bioactive Food Compounds with Cancer Preventing Effects in the Colon Focus on Ferulic Acid, para-Coumaric Acid and Lactoferricin

    Författare :Birgit Janicke; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Caco-2; Gene expression; Cell proliferation; Cell cycle; Bioactive food compounds; Colon cancer; Ferulic acid; para-Coumaric acid; Lactoferricin;

    Sammanfattning : Colorectal cancers are globally ranked as the third most common cancer form in terms of incidence and mortality. Diet has long been considered as one of the main factors affecting population outcome regarding development of cancer in the colon. LÄS MER

  5. 14. Rift Valley fever : challenges and new insights for prevention and control using the “One Health” approach

    Författare :Osama Ahmed Hassan Ahmed; Magnus Evander; Clas Ahlm; Joacim Rocklöv; Maria Van Kerkhove; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rift Valley fever; Sociocultural practices; Community involvement; Ecological factors; Risk map; Early warning system; Surveillance system; International Health Regulations; and One Health approach.; Epidemiology; epidemiologi; folkhälsa; Public health;

    Sammanfattning : Rift Valley fever (RVF) is an emerging viral zoonosis that causes frequent outbreaks in east Africa and on the Arabian Peninsula. The likelihood of RVF global expansion due to climate change and human anthropogenic factors is an important issue. LÄS MER

    Författare :Hadi Amin; Mohammad Bagherbandi; Lars Sjöberg; Faramarz Nilfouroushan; Martin Horwath; Högskolan i Gävle; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geodetic reference system; geoid potential; global vertical datum; climate change; global warming; mass change; ice melting; sea-level change; remote sensing; satellite gravimetry; geodetiska referenssystem; geopotential; globala vertikala datum; klimatförändring; global uppvärmning; massförändring; issmältning; havsnivåförändring; fjärranalys; satellitgravimetri;

    Sammanfattning : Our complex planet is continuously undergoing temporal and spatial changes. In this context, ongoing processes in the Earth subsystems (geosphere, biosphere, cryosphere, hydrosphere, and atmosphere) cause changes in the gravity field of the Earth across a wide range of temporal and spatial scales.
