  1. 16. NH Planetary-Scale Circulation in Troposphere and Stratosphere: A Spectral and Dynamical Perspective

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Michael Konrad Schutte; [2023]
    Keywords : jet stream; Rossby waves; polar vortex; spectral analysis; dynamic systems theory; sudden stratospheric warmings; strong polar vortex events; jetström; Rossbyvågor; polär virvel; spektralanalys; dynamisk systemteori; plötsliga stratosfäriska uppvärmingar; starka polvortexhändelser;

    Abstract : Dynamic Systems Theory (DST) and spectral analysis are employed to study the tropospheric jet stream and the stratospheric polar vortex. The objective is to investigate the relationship between Rossby wave activity and inverse persistence and dimensionality of geopotential height at 250 hPa and 10 hPa, as these two dynamical indicators are expected to show a characteristic behavior of Rossby wave harmonics.

  3. 17. Real time estimations of kLa and viscosity in a fermentation pilot plant

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Arvid Norberg; [2022]
    Keywords : Oxygen transfer; Viscosity; Fermentation; Biotechnology; Direct method; kLa; OUR; DO; Online monitoring; Soft sensor; Fungus; Fungal fermentation; A. oryzae; A. niger; Herschel-Bulkley; Power law; Shear thinning; Novozymes; Enzymes; Technology and Engineering;

    Abstract : Fermentation is a process that utilizes live microorganisms to produce different biological products such as enzymes. The oxygen mass transfer rate is often the limiting factor in aerobic fermentations and thereby an important process parameter. READ MORE

  4. 18. Spatial patterns of Dissolved Organic Matter in Swedish Surface Waters

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Anna Lackner; [2022]
    Keywords : Dissolved Organic Matter; Brownification; Digital Mapping; Soil Moisture; Stream Length;

    Abstract : Dissolved organic matter (DOM) in surface water has been widely studied, in part due to its significance for aquatic ecology and drinking water quality. Across Sweden, increases in the total organic carbon (TOC) concentrations and color of surface waters, known as brownification, were noted in the decades before and after year 2000, though recent analysis has found widespread DOM increase to have ceased after 2010.

  5. 19. Conditions to authorise subcontracting in fashion and apparel industry : a brand's perspective

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

    Author : Clara Maria Rosa Boehler; [2022]
    Keywords : fashion and apparel industry; supply chain management; social exchange; buyersupplier relationship; subcontracting; unauthorised subcontracti;

    Abstract : In current supply chains, the context of subcontracting is majorly connected to unauthorised subcontracting with negative conjunction which has created the fear of discussing subcontracting. However, previous research presents subcontracting as a common practice within fashion and apparel supply chains, however, nearly no study has focused on elaborating the authorisation process.

  6. 20. Waste Heat Driven Membrane Distillation Integrated with Stirling Engine

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Jonatan Talåsen; Niklas Bergman Larsson; [2022]
    Keywords : Carnot batteries; Stirling engine; Azelio AB; Scarab Development; Thermal Energy Storage TES; Membrane Distillation; Air Gap Membrane Distillation; Waste heat integration; Water scarcity; Power on demand; Sustainability; Carnotbatterier; Stirlingmotor; Azelio AB; Scarab Development; Termisk Energi lagring TES; Membrandestillation; Air Gap Membrane Distillation; Spillvärmesintegration; Vattenbrist; Ström på begäran; Hållbarhet;

    Abstract : In this thesis, the potential to purify water utilizing waste heat from a unit which stores thermal energy and converts it to electricity is studied. The unit, called TES.POD, is developed by Azelio AB and is in this thesis used as a heat source to drive an air gap membrane distillation (AGMD) unit developed by Scarab Development AB. READ MORE
