1. 21. Exploring food concepts for the prevention of type 2 diabetes

   Författare :Ulrika Axling; Molekylär endokrinologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glycaemic index; whole grain; Type 2 diabetes; obesity; rose hip;

   Sammanfattning : There is currently a dramatic and global increase in obesity, type 2 diabetes (T2D) and associated metabolic disorders. T2D can be delayed or prevented in individuals at risk and identifying and developing new food concepts for the prevention of obesity and T2D is of utmost importance. LÄS MER

3. 22. Hygiene Aspects of Greywater and Greywater Reuse

   Författare :Jakob Ottosson; KTH; []
   Nyckelord :greywater; greywater reuse; greywater treatment; microbial risk assessment; groundwater recharge; irrigation; recreational water; faecal contamination; indicator bacteria; index organisms; faecal sterols; bacteriophages; enteric pathogens; rotavirus; ;

   Sammanfattning : Greywater is domestic household wastewater without inputfrom the toilet, i.e. wastewater from sinks, the shower,washing machine and dishwasher in a home. Source separation ofgreywater can be a strategy to enhance recirculation of plantnutrients and/or improve water use. LÄS MER

4. 23. Application of ozone in wastewater treatment : Oxidation of pharmaceuticals and filamentous bulking sludge

   Författare :Filip Nilsson; Avdelningen för kemiteknik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ozone; Filamentous Sludge; Pharmaceuticals; Wastewater Treatment; Ozone; Filamentous bulking sludge; Pharmaceutical reduction;

   Sammanfattning : As pharmaceutical removal was not part of the of the modern wastewater treatment plant (WWTP) design, it is not surprising that WWTPs have been identified as major point sources of pharmaceuticals entering the environment. The oxidation of pharmaceuticals in the WWTP effluent is one of the-end-of-pipe solutions that are considered most ready for full-scale use. LÄS MER

5. 24. Influence of acid hydrogen peroxide treatment on refining energy and TMP properties

   Författare :Karin Walter; Per Engstrand; Magnus Paulsson; Lennart Salmén; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TMP; Black Spruce; Energy reduction; Hydrogen peroxide; Ferrous sulphate; Refining; Inter-stage treatment; Pulp and paper properties; Fenton´s reagent; Bleaching; Sodium dithionite; Brightness; Metals; Fibre dimensions; Cross-sectional dimensions; Chemical composition; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Sammanfattning : The potential of using acid hydrogen peroxide under Fenton conditions to lower the electrical energy consumed during the production of Black spruce (Picea mariana) thermomechanical pulp (TMP) was investigated. The chemical system, which consisted of ferrous sulphate, hydrogen peroxide and optionally an enhancer (3,4-dimethoxybenzyl alcohol, ethylenediaminetetraacetic acid or oxalic acid/sodium oxalate), was evaluated as an inter-stage treatment where the primary refiner was used as a mixer.

7. 25. Selected Topics in Mathematical Modelling: Machine Learning and Tugs-of-War

   Författare :Carmina Fjellström; Kaj Nyström; Andrea Pascucci; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Machine learning; Neural networks; LSTM; Financial forecasting; Time series analysis; Stochastic gradient descent; Diffusion map; Dimension reduction; Tug-of-war games; Fractional heat operator; Mean value property; Infinity fractional heat operators; Dynamic programming principle; p-Laplacian; Infinity Laplacian; Kolmogorov equation; Stochastic games; Viscosity solutions; Tillämpad matematik och statistik; Applied Mathematics and Statistics;

   Sammanfattning : This thesis concerns selected topics in mathematical modelling, namely in machine learning and stochastic games called tugs-of-war. It consists of four scientific articles. The first and second are about machine learning topics, while the third and fourth articles are about tug-of-war games. LÄS MER
