  1. 1. Ash Products for Nutrient Recycling in Forestry : Leaching and Drying Characteristics

    Author : Peter Mellbo; Högskolan i Kalmar.; [2007]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Ash products; Wood ash; Leaching; Drying; Nutrient; ; Sustainable forestry; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING Plant production Forestry; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING Växtproduktion Skogsskötsel; Miljövetenskap; Environmental Science;

    Abstract : As the demand for carbon dioxide neutral energy sources increases, forestry becomes more intensive. Entire trees are removed from the felling sites threatening the nutrient balance of the forest soils. READ MORE

  2. 2. PLANT-BACTERIAL AND PLANT-FUNGAL COMPETITION FOR NITROGEN AND PHOSPHORUS

    University dissertation from Katarina Månsson, Department of Ecology (Plant Ecology and Systematics), Ecology Building, Lund University, 223 62 Lund

    Author : Katarina Månsson; Lund University.; Lunds universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Växtekologi; Amino acid; 15N; Soil C:N ratio; Plant ecology; Soil drying-rewetting;

    Abstract : Competition between and within species has been one of the most studied concepts in ecology. In this thesis the aim was to test the idea of plant-microbial competition for N and, by studying this interaction, to gain a better understanding of different N processes in soil. READ MORE

  3. 3. Retrofitting CHP Plant and Optimization of Regional Energy System

    University dissertation from Västerås : Mälardalen University

    Author : Song Han; Mälardalens högskola.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; annual performance; combined heat and power; drying; ethanol; integration; part-load.; årliga prestation; kraftvärme; torkning; etanol; integration; del-last.; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : The use of biomass-based combined heat and power (CHP) plants is considered by the EU administration to be an effective way to increase the use of renewables in the energy system, to reduce greenhouse gas emissions and to alleviate the dependency on imported fossil fuels. At present in Sweden, most of the CHP plants are operated in part-load mode because of variations in heat demand. READ MORE

  4. 4. Utilization of Wild Fruit in Mozambique – Drying of Vangueria infausta (African medlar)

    University dissertation from Food Technology, Engineering and Nutrition, Lund University

    Author : Eulália Chiau; Lund University.; Lunds universitet.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vangueria infausta; drying; maltodextrin; sucrose; softener; toughness; solar-assisted pervaporation; aroma; crystallization; water activity;

    Abstract : Vangueria infausta (African medlar) is a wild fruit found in southern and central Mozambique. The ripe fruit has a leathery skin enclosing three to five seeds embedded in a soft pulp that tastes like apple. It plays an important role in the diet of the rural population and has the potential for commercial use. READ MORE

  5. 5. Pulsed Electric Field Treatment of Plant Tissue

    University dissertation from Mustafa Fincan ([email protected]), or Dept of Food engineering, Lund University, or The library; UB , Lund University

    Author : Mustafa Fincan; Lund University.; Lunds universitet.; [2003]
