2. 1. Land Matters : Agrofuels, Unequal Exchange, and Appropriation of Ecological Space

   Author : Kenneth Hermele; Humanekologi; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Land; Agrofuels; Ecologically unequal exchange; Environmental load displacement; Land grabbing; Malthus; Brazil; Ethanol; Resource wars; Land Use change; Indirect land use change;

   Abstract : As a global society we are entering an era where land areas and land-based resources are coming to the fore once again for capital accumulation and economic growth, for the first time since the end of the 18th century when Malthus forecasted a contradiction between population growth and agricultural output. That constraint on economic growth, imposed by limited land areas, was overcome by the combination of fossil fuels (coal, oil) and appropriation of space overseas (colonialism, trade). READ MORE

4. 2. Weathering of till in northern Sweden and its implications for the geochemistry of soil water, groundwater and stream water

   Author : Magnus Land; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

   Abstract : Natural exogenic geochemical processes in northern Sweden have been studied. The thesis is focused on field weathering rates and variations in the chemical composition of water with time and space. Variations in weathering rates of silicate minerals are important for the global CO2 cycle, and thus also for climatic changes. READ MORE

5. 3. Laboratory method for the study of moisture-induced waviness in paper

   Author : Cecilia Land; Göran Ström; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; method; moisture; paper; paper web; wavelength; waviness; Cellulose and paper engineering; Cellulosa- och pappersteknik; Chemical Engineering; Kemiteknik;

   Abstract : Paper that is subjected to moisture undergoes dimensional changes. It expands during moistening and shrinks during drying. When the paper is under tension between rollers, the effects are complex since shrinkage and expansion are restricted in the width direction. Waves can then appear on the paper web. READ MORE

6. 4. Software Systems In-House Integration : Observations and Guidelines Concerning Architecture and Process

   Author : Rikard Land; Ivica Crnkovic; Christer Norström; Christine Hofmeister; Mälardalens högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Architectural Compatibility; Software Architecture; Software Integration; Software Merge; Software Processes; Strategic Decisions; Computer science; Datalogi; Datavetenskap;

   Abstract : Software evolution is a crucial activity for software organizations. A specifc type of software evolution is the integration of previously isolated systems. The need for integration is often a consequence of different organizational changes, including merging of previously separate organizations. READ MORE

7. 5. Modelling regional climate-vegetation interactions in Europe : A palaeo perspective

   Author : Gustav Strandberg; Erik Kjellström; Qiong Zhang; Johan Nilsson; Hans Renssen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Palaeoclimate; climate model; vegetation; vegetation changes; land-cover; changes; proxy data; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Abstract : Studies in paleoclimate are important because they give us knowledge about how the climate system works and puts the current climate change in necessary perspective. By studying (pre)historic periods we increase our knowledge not just about these periods, but also about the processes that are important for climatic variations and changes. READ MORE
