  1. 21. Characterization of bovine milk from indigenous species from Sri Lanka

    University essay from SLU/Department of Molecular Sciences

    Author : Jonathan Skager; [2022]
    Keywords : Milk; total proteolysis; protein profile; capillary electrophoresis; fluorescence; indigenous cattle; Jersey cattle; Friesian cattle; Sri Lanka;

    Abstract : Sri Lanka is a country in south Asia that from the beginning of the 21st century, until 2016 almost doubled their quantity in milk import, this to meet their national market demand for dairy products. The country is divided into different agroecological zones, which are the up-country, mid-country, and the lowlands. READ MORE

  3. 22. Parameter Update Schemes for Hidden Markov Models applied to Financial Returns

    University essay from Lunds universitet/Matematisk statistik

    Author : Sigfrid Forsberg; [2022]
    Keywords : Markov Chain; Finance; Hidden Markov Model; Generalized Autoregressive Score Model; S P-500; Nikkei; Adaptive Model; Volatility; Regime-switching Model; Line-Search Algorithm; Predictor-Corrector; Quasi-Newton; Mathematics and Statistics;

    Abstract : This thesis was dedicated to investigating the use of different parameter update schemes for Hidden Markov models with time-varying parameters, with an emphasis on developing alternatives to the quasi-Newton step. The focus was on applications to financial returns, using data from the S\&P-500 and the Nikkei index, and for comparison, a trial using synthetic data was also performed. READ MORE

  4. 23. Optimization of a two-step anaerobic treatment of wastewater from the Pulp and Paper Industry

    University essay from KTH/Industriell bioteknologi

    Author : Sara Bard; [2022]
    Keywords : Wastewater treatment; biogas; methane; pulp and paper mill wastewater; wood raw material; anaerobic treatment; sulphate reduction; UAPB reactor; Vattenrening; biogas; metan; processvatten från pappers- och massaindustrin; träråvara; anaerob rening; sulfatreduktion; UAPB reaktor;

    Abstract : Under de senaste 30 åren så har antalet massa- och pappersbruk minskat medan den totala produktionen av massa och papper har ökat. En högre produktion per bruk tillsammans med en hårdare miljölagstiftning, sätter ett högre tryck på vattenreningen på varje bruk. READ MORE

  5. 24. The role of bed sediments for fractionation of phosphorus in remediated ditches in Sweden

    University essay from SLU/Dept. of Soil and Environment

    Author : Emma Ryding; [2022]
    Keywords : Phosphorus fractionation; agricultural stream; sediment; two-stage ditch; eutrophication;

    Abstract : Sweden’s environmental quality objectives “A varied agricultural landscape” and “Zero eutrophication”, aims to ensure food production while reducing negative impact from fertilizers on the environment. The input ceilings of nutrient concentrations in the Baltic Sea are still critical. READ MORE

  6. 25. Polymer-based additive manufacturing: optimization for high-performance degradable polymers

    University essay from KTH/Fiber- och polymerteknologi

    Author : Danjing Chen; [2022]
    Keywords : copolymerization; fused filament fabrication; degradable polymer; scaffold; 3D printing; sampolymerisering; tillverkning av filament; nedbrytbar polymer; tredimensionella matriser; 3D printing;

    Abstract : I det här utvecklas en reproducerbar polymerisationsmetod för att uppnå en stabil produktion av poly(ε-caprolakton-co-p-dioxanon) (PCLDX), skala upp filamenttillverkningen för att producera 1.75 mm långa filament och optimera 3D-utskriftsprocessen för att tillverka ställningar/anordningar för mjukvävnadsteknik.
