  1. 1. Naturbaserad dagvattenhantering : gestaltningsförslag för främjandet av Bäcklösabäckens mångfald och rekreation

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Urban and Rural Development

    Författare :Alexandra Fabian; [2024]
    Nyckelord :Analys genom syntes; dagvattendamm; biologisk mångfald; Bäcklösabäcken; tvåstegsdike; gestaltning; rekreation; ekologi; våtmark; meandring; vegetationszoner; svämplan;

    Sammanfattning : I takt med att Uppsalas utvecklingsområde Södra staden expanderas, minskar stadens grönområden och permeabla ytor för dagvattnet att infiltrera. Detta leder både till en förlust av biologisk mångfald, ekologiska spridningsvägar och en större belastning på Bäcklösas avrinningsområde som täcker stora delar av Södra staden. LÄS MER

  2. 2. Production of natural pigments from A. platensis grown on wastewater from local treatment facility.

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Författare :Hana Faulds; [2023]
    Nyckelord :Cyanobacteria; pigments; microalgae; wastewater treatment; biotechnology; Technology and Engineering; Biology and Life Sciences;

    Sammanfattning : Although microalgae have been considered for the biological treatment of wastewater since the 1950’s, their potential to efficiently remove pollutants from various streams remains largely untapped and is yet to be utilized at large scale. The production of algal biomass and extraction of high-value compounds has, however, become increasingly popular with large scale farms and biorefineries around the world producing many promising alternatives to petroleum-based products and processes.

  3. 3. Navigating Large-Scale Plasmid DNA Purification : A Recommendation of Current and Future Downstream Purification Solutions

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Matilda Eriksson; Alva Wells; Maria Frey; Lisa Johansson; Gabriel Pettersson; David Sjöberg; [2023]
    Nyckelord :Plasmid purification; pDNA; large-scale chromatography;

    Sammanfattning : Previous small-scale methods for plasmid DNA (pDNA) purification fail to meet theindustry’s demand for sufficient quantities. Greater volumes of bacterial lysates are a consequence of larger volumetric fermentations and traditional large-scale down-stream purification processes have some disadvantages and limitations.

  4. 4. Assessment of the integration of solar heat power into food drying processes

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Charalampos Psilopoulos; [2023]
    Nyckelord :Sustainable; sustainability; co2 reduction; feasibility; solar thermal; direct steam generation; drying; food industry; scope 1 emissions; sdg; sustainable development goals; spray drying; drum drying; powder; food; Technology and Engineering;

    Sammanfattning : The long-lasting usage of fossil fuels has brought its negative impact on the planet and thus the society is turning towards more environmentally sustainable solutions in every aspect of life. This master’s thesis discusses the novel topic of integrating concentrated solar thermal collectors, which directly produce steam, to drying processes in the food industry, which is proven to currently emit significant amounts of Greenhouse Gases (GHGs).

  5. 5. Automatisering av det interna flödet på ett tillverkande företag : En studie om den interna hanteringen av kretskortställningar och hur det kan effektiviseras i flödet

    Kandidat-uppsats, Jönköping University/JTH, Industriell produktutveckling, produktion och design

    Författare :Ahmed Kadhim Abed; Erik Rappestad; [2023]
    Nyckelord :Transport flow; Circuit board racks; Automation; AMR systems; Waste; Bottlenecks.; Transportflöde; Kretskortställningar; Automatisering; AMR-system; Slöseri; Flaskhalsar;

    Sammanfattning : Purpose: The purpose of the study was to identify the current transport flow for circuit board racks and to investigate the potential implementation of an automated solution for the transportation of circuit board racks in order to increase efficiency in the flow. The research questions answered during this study were: What does the transport flow for circuit board racks look like today?  What could an automated transport flow for circuit board racks look like?  Is an automated transport flow for circuit board racks a sufficient solution to improve efficiency in the flow? Theoretical framework: The study applied several different theories, with waste being a central part. LÄS MER
