  2. 1. Theoretical Optimization of Compressive Crushing

    Author : Elisabeth Lee; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Consumption; Fitness Function; Genetic Evolutionary Algorithms; Crushing Pressure; Optimization; Product Yield; Compressive Crushing;

    Abstract : Surrounded by products made from crushed rock materials in all corners of society, most people do not spend much time thinking about when, where, or how these are produced. In fact, most people take the supply and availability of products made from crushed rock materials for granted. READ MORE

  4. 2. Yeast biotechnology for nutritional improvements of fermented cereal-based foods - Phytate degradation and folate production

    Author : Andreas Hellström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mineral availability; phosphate; togwa; starter culture; Yeast; food fermentation; phytase; phytate; folate;

    Abstract : Anaemia is a serious public health problem in nearly all developing countries. It has negative consequences on cognitive and physical development of children, reduces work capacity in adults, and increases the risk of maternal and child mortality. READ MORE

  5. 3. Quantification of mineral weathering rates in sulfidic mine tailings under water-saturated conditions

    Author : Magdalena Gleisner; Docent Roger Herbert; Professor Emeritus Rolf Hallberg; Dr. Magnus Land; Professor Patrick Crill; Mats Åström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mine tailings; pyrite; sulfides; weathering; oxygen availability; Acidithiobacillus ferrooxidans; Earth sciences; Geovetenskap;

    Abstract : Tailings are a fine-grained waste product produced during the metal recovery process. Tailings consist mostly of different silicates but also sulfides (e.g. pyrite), since 100 % metal recovery is not possible. READ MORE

  7. 5. On the investigation of chemical parameters reflecting microbial activity linked to nutrient availability in forest soil

    Author : Madelen Olofsson; Dan Bylund; Bengt-Gunnar Jonsson; Bjarne W. Strobel; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Boreal forest; electrospray ionization; fungal biomass; hydrophilic interaction chromatography; hydroxamate siderophores; liquid chromatography-mass spectrometry; mineral amendment; aromatic acids; podzol soil;

    Abstract : As agrarian society developed, the most fertile soils able to sustain the nutritional requirements needed for high crop yield were assigned to farming, while the more penurious soils were left to uphold the forest ecosystems. Some temperate forests are developed on acidic soils considered to be nutrient poor, as much of the inorganic nutrients are entrapped in poorly weatherable soil minerals and not easily accessed by plant roots.
