  2. 11. (Not) Representing Cycling : Exploring the subjugation and multiplicity of cycling

    Author : Daniel Valentini; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : Cycling is often represented as a symbol of sustainable mobility change. This thesis builds on the argument that even in acclaimed cycling cities possibilities for cycling to become part of transformative change are stifled. READ MORE

  4. 12. Nutrient cycling in agroecosystems: nitrogen cycling in southern Sweden in the 1850s and two Tanzanian villages in the 1990s

    Author : Lars-Erik Williams; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nutrient; nutrient model; nutrient cycling; nitrogen fixation; nitrogen budget; mixed system; miombo; manure; livestock; land use; historical system; food production; efficiency; crops; agroecosystem; carrying capacity; phosphorus; Scania; sustainability; Plant ecology; Växtekologi;

    Abstract : This study presents a general model for analysing nutrient cycling in agroecosystems. The focus is on food production intensity, human carrying capacity, sustainability and efficiency. The model can be used on systems including different kinds of land uses, which makes it applicable for studies on different scales. READ MORE

  5. 13. Chlorine Cycling in Terrestrial Environments

    Author : Malin Montelius; David Bastviken; Teresia Svensson; Katarina Abrahamsson; Linköpings universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chloride; organic chlorine; chlorination; dechlorination; 36Cl; risk assessment modelling; Klorid; organiskt klor; klorering; deklorering; klor-36; riskmodellering;

    Abstract : Chlorinated organic compounds (Clorg) are produced naturally in soil. Formation and degradation of Clorg affect the chlorine (Cl) cycling in terrestrial environments and chlorine can be retained or released from soil. READ MORE

  6. 14. Metabolic and Cardiovascular Responses During Variable Intensity Exercise

    Author : Glenn Björklund; Mittuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cross-country skiing; cycling; heart rate; lactate; O2 extraction; O2 uptake; performance; ventilation; Sports; Idrott;

    Abstract : Previous research investigating endurance sports from a physiological perspectivehas mainly used constant or graded exercise protocols, although the nature ofsports like cross-country skiing and road cycling leads to continuous variations inworkload. Current knowledge is thus limited as regards physiological responses tovariations in exercise intensity. READ MORE

  7. 15. Numerical optimization of pacing strategies in locomotive endurance sports

    Author : David Sundström; Mats Tinnsten; Peter Carlsson; Mikael Bäckström; Erik Bruun Simonsen; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pacing strategy; optimization; numerical simulation; equations of motion; method of moving asymptotes; cross-country skiing; cycling; Farthållningsstrategi; optimering; numerisk simulering; rörelseekvationer; method of moving asymptotes; längdskidåkning; cykling;

    Abstract : This thesis is devoted to the optimization of pacing strategies in two locomotive endurance sports; cross-country skiing and road cycling. It has been established that constant pace and variable power distributions are optimal if purely mechanical aspects of locomotion are considered in these sports. READ MORE
