2. 16. Pre-school Children’s Food Habits and Meal Situation : Factors Influencing the Dietary Intake at Pre-school in a Swedish Municipality

   Author : Hanna Sepp; Margareta Wandel; Uppsala universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Domestic sciences; children; food; meals; nutrient; pre-school; teachers; Hushållsvetenskap; barn; mat; måltider; förskola; lärare; Domestic science and nutrition; Hushålls- och kostvetenskap;

   Abstract : A pre-school-based dietary survey, using seven-day records, focus group interviews and semi-structured interviews, was carried out in a suburban area of Stockholm. The overall objective was to investigate the individual food and nutrient intake of pre-school children at all meals during the day, as well as factors that might influence children’s intake.

4. 17. Dynamic single-cell modelling of nutrient signalling in budding yeast

   Author : Sebastian Persson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nutrient signalling; single-cell; mixed-effects models; stochastic dynamic models; Bayesian inference;

   Abstract : To survive in environments with constantly changing nutrient levels the bud- ding yeast Saccharomyces cerevisiae has a sophisticated nutrient sensing system. A central component of this system is the SNF1 signalling pathway, which primarily helps yeast adapt to glucose limited conditions. READ MORE

5. 18. Dynamics of nutrient mass transport : A river basin evaluation

   Author : Gunnar Karlsson; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Motala ström; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Abstract : Human settlements and activities can dramatically change and accelerate the rate of eutrophication in a river basin. An undesirable increase in the input of nutrients, e.g. phosphorus and nitrogen, to a surface water causes adverse water quality conditions. READ MORE

6. 19. Organic acids in root exudates and soil solutions. Importance to calcicole and calcifuge behaviour of plants

   Author : Lena Ström; Institutionen för naturgeografi och ekosystemvetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; nutrient-solubilisation; iron; phosphate; nutrient-limitations; citrate; oxalate; organic acids; root exudation; acidifuge; Calcicole; calcifuge; adaptations.; Plant ecology; Växtekologi;

   Abstract : Many vascular plant species are unable to colonise calcareous sites, the floristic composition of adjacent limestone and acid silicate soils differing markedly. The inability of these 'calcifuge' species to establish themselves and grow on limestone soil appears to mainly be related to their low capacity for solubilising and absorbing phosphate and/or iron from such soils.

7. 20. Resource recovery from wastewater treatment: challenges, opportunities and guidance for planning and implementation

   Author : Mariana Cardoso Chrispim; Miklas Scholz; Marcelo Antunes Nolasco; Jennifer R. McConville; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circular economy; Resource recovery; Sewage; Planning; Water; Nutrient; Biogas; Developing countries; Urban areas;

   Abstract : Considering the current resources scarcity, Wastewater Treatment Plants (WWTP) should be adapted to become more sustainable. For example, it is possible to recover resources present in municipal wastewater. READ MORE
