  1. 1. Inclusion of blue mussels in the diet of Black Soldier Fly (Hermentia illucens) : the effect on compost process efficiency

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Alma Jennersjö Hedman; [2022]
    Keywords : Black Soldier Fly; Hermetia illucens; larvae composting; process efficiency; circular economy; animal food production;

    Abstract : Abstract The management and handling of organic waste in primarily low-income developing cities, due to high urbanization has become a global problem. The main form of waste handling in these cities are landfilling, due to it being the cheapest and easiest option. READ MORE

  3. 2. Comparing different methods of measuring particle size for pharmaceutical excipients

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Jiawen Wang; [2022]
    Keywords : particle size; comparison; Malvern analysis; Qicpic analysis; Pharmaceutical technology; Technology and Engineering;

    Abstract : In pharmaceutical science, particle size is one of the most fundamental parameters of materials, but different particle-sizing analysis methods lack a uniform standard for measuring irregular particle size, making it difficult to compare the accuracy and applicability of different particle-sizing analysis methods. Experiments on excipients used in pharmaceuticals are carried out in this paper by laser diffraction analysis (Malvern wet and dry), dynamic image analysis (Qicpic), and microscopic methods (Qicpic, SEM, and light microscopy) to determine the applicability and limitations of each method, as well as to clarify their advantages and disadvantages.

  4. 3. Towards Understanding slag build-up in a Grate-Kiln furnace : A study of what parameters in the Grate-Kiln furnace leads to increased slag build-up, in a modern pellet production kiln

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Oscar Olsson; Uno Österman; [2022]
    Keywords : Grate-kiln; Slag; Interpretable machine learning; IID; independent and identically distributed; Kulsinter; pellets; slagg; slag; LKAB;

    Abstract : As more data is being gathered in industrial production facilities, the interest in applying machine learning models to the data is growing. This includes the iron ore mining industry, and in particular the build-up of slag in grate-kiln furnaces. READ MORE

  5. 4. Change of heating fuel consumption patterns produced by the economic crisis in Greece

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Panagiotis Patrinos; [2021]
    Keywords : geography; GIS; atmospheric pollution; Greece; household heating systems; heating fuel; economic Crisis; air Quality; satellite data; virtual stations; regression analysis; air pollutants mapping; anthropogenic factors; Earth and Environmental Sciences;

    Abstract : The economic crisis in Greece resulted in a change in residential heating fuels utilized, which in turn resulted in a change of air quality over Greater Athens Area. The aim of this study was to investigate the effects of economic crisis in air quality over Attica by examining the change in air pollutants’ concentrations before, during, and after the onset of the economic crisis in Greece and to associate this change with the change in fuels used for residential heating.

  6. 5. Characterization of uranium oxide powders and sinterability

    University essay from KTH/Kemiteknik

    Author : Joakim Ceder; [2021]
    Keywords : uranium dioxide; sinterability; reduction; pore former; chemical activity; urandioxid; sintringsaktivitet; reduktion; porbildare; kemisk aktivitet;

    Abstract : Uranoxid (UOx) är ett energitätt material som ofta används i kärnbränsle. UOx-pulver pressas och sintras för att tillverka urandioxidkutsar som förs in i bränslestavar. Stavarna monteras slutligen ihop till ett bränsleknippe. Tillverkningsprocessens stabilitet och förutsägbarhet är viktiga. READ MORE
