  1. 1. Jordbrukspolitiska stödformer : en studie av SR-, A- och B-stödens lokala effekter 1961-1981

    Författare :Rolf S. Johnsson; Umeå universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Swedish agriculture; structural rationalization; government support; government subsidy; special rationalization SR ; evaluation; agricultural policy;

    Sammanfattning : The aim of this study has been to analyse the effects of state subsidies within agriculture. The goal of these policies was to build up long-term sound and profitable farms by means of both general and selective support measures. LÄS MER

  3. 2. Process development for platform chemical production from agricultural and forestry residues

    Författare :David Nickel; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Biorefinery; pretreatment; lignocellulose; multi-feed SSCF; preadaptation; multi-scale variability analysis; platform chemicals; lactic acid; logging residues; mixed feedstocks; ethanol;

    Sammanfattning : As part of a bio-based economy, biorefineries are envisaged to sustainably produce platform chemicals via biochemical conversion of agricultural and forestry residues. However, supply risks, the recalcitrance of lignocellulosic biomass, and inhibitor formation during pre­treatment impair the economic feasibility of such biorefineries. LÄS MER

  4. 3. Greenhouse gas emissions from Swedish milk production : towards climate-smart milk production

    Författare :Maria Henriksson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : 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. LÄS MER

  5. 4. Quality of organically produced wheat from diverse origin

    Författare :Abrar Hussain; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The health benefits of organically grown whole grain wheat are derived from various nutritional compounds such as dietary fibre, minerals, vitamins and phytochemicals, while baking quality is influenced by the protein content and composition. Genetic improvement and production of wheat to increase the amounts of the nutritional compounds therefore enhance the health benefits. LÄS MER

  7. 5. Governing grain protein concentration and composition in wheat and barley : use of genetic and environmental factors

    Författare :Ali Hafeez Malik; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : For commercial production of wheat and barley, grain yield (GY), grain protein concentration (GPC) and protein composition are considered important. Genetic (G) and environmental (E) factors are important constraints affecting GPC and protein composition in wheat and barley. LÄS MER
