  1. 1. A computational model of metapopulation dynamics and organism-mediated nutrient flow

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Amanda Hansson; [2023-08-07]
    Keywords : computational model; population dynamics; metapopulation dynamics; nutrient flow; simulation; spatially explicit; individual-based;

    Abstract : The aim of this project was to assess, using in-silico experiments, how different life history char-acteristics, such as age at maturity and dispersal ability of individuals, influence the dynamics of a metapopulation. To achieve this, a novel model of a spatially explicit metapopulation, with organ-ism-mediated nutrient flow between fragmented habitat patches, was implemented by means of computer simulations.

  3. 2. Modelling the chemical recycling of plastic waste via pyrolysis and analysing integration with existing refinery infrastructure

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Simon Dahl; [2023]
    Keywords : Pyrolysis; Recycling; Integration; Modelling; Simulation; Techno-economic; Plastic; Chemical engineering; Technology and Engineering;

    Abstract : Current plastic management is unsustainable as large amounts of plastic end up landfilled or in the ocean, necessitating an expansion of waste management infrastructure. Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. READ MORE

  4. 3. Pyrolysis of Municipal Sewage Sludge to get a phosphorus rich char residue for soil improvement

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Shahin Shamim; [2023]
    Keywords : Sewage Sludge-Phosphorus-Pyrolysis- Heavy metals; Cadmium; Lead; Nickle; Copper; Chromium; Zinc; Biochar; Heating value; Fertilizer- Thermal conversion;

    Abstract : Sewage sludge is a byproduct of wastewater treatment plants. It is a kind of waste. however, it contains several valuable nutrients like phosphorous and nitrogen that are used to rich the soil as a fertilizer compound. READ MORE

  5. 4. Evaluating the effects of climate change on Arctic char : including impacts of brown trout competition

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Ola Carlström; [2023]
    Keywords : arctic char; brown trout; climate change; diet; habitat use; temperature;

    Abstract : Climate change is predicted to increase the average global temperature with 1.5 °C between 2030 and 2052. The areas that are most vulnerable for climate change are the arctic regions. Arctic char (Salvelinus alpinus) is a cold-water salmonid species with the most northern distribution of all freshwater fish species. READ MORE

  6. 5. Size effect in wood : Characterization of mechanical properties using digital image correlation method

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Amir Saeidi; Olafur Johannsson; [2023]
    Keywords : compression test longitudinal direction; digital image corre- lation DIC ; ncorr; phyton; pinewood; size effect; stiffness matrix; wood- construction; YAWCAM; young’s modulus; digital image correlation DIC ; elasticitetsmodul; furu; kom- pressionstest längs fiberriktning; ncorr; phyton; storlekseffekt; styvhetsma- tris; trä-konstruktion; YAWCAM;

    Abstract : As a natural composite material, wood exhibits complex structural char-acteristics and diverse behavior under compression and tensile forces. Itsanisotropic nature results in mechanical properties that vary depending onthe load direction along its longitudinal, tangential, and radial grains. READ MORE
