  1. 16. Investigation of different ventilation profiles to avoid stratification in Nearly Zero Energy Buildings

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Alazne Irene Varela Santana; [2023]
    Keywords : stratification; water model; comfort; mixing; temperature; potential energy; net zero energy building;

    Abstract : This research paper examines possible solutions for the problems that warm air heating is suffering in Nearly Zero Energy Buildings. These NZEBs are passive houses constructed to have high energy efficiency where the quantity of power used is equal to the power created annually, produced locally or in the surroundings by renewable energy sources.

  3. 17. Water use efficiency in agricultural irrigation in Egypt: A qualitative study on the complexities of utilising fossil groundwater resources in the face of water scarcity

    University essay from Lunds universitet/Ekonomisk-historiska institutionen

    Author : Johannes David Huber; [2023]
    Keywords : Water scarcity; water use efficiency; agricultural irrigation; desert farming; sustainability; groundwater extraction; Nubian Sandstone Aquifer System NSAS ; Business and Economics;

    Abstract : This study examines the adaptive capacity of desert farming in Egypt to imminent water scarcity and discusses the sustainability of fossil groundwater extraction. Through qualitative semi-structured expert interviews, the study identifies clear research and data gaps related to the Nubian Sandstone Aquifer System (NSAS) and highlights the need for a nuanced approach to fossil groundwater extraction that focuses on water use efficiency improvements.

  4. 18. Sustainable water treatment in the manufacturing industry : Investigation of the water treatment system at VCE, Hallsberg

    University essay from Linköpings universitet/Energisystem

    Author : Johan Hagströmer; Forsberg Emma; [2023]
    Keywords : ;

    Abstract : Transitioning to circular flows is essential to economize the planet’s resources. One of the most important resources on earth is water as it is vital for all living things. However, water purification methods have proven to be very energy intensive, and increasing the circular water flows is therefore challenging. READ MORE

  5. 19. Automation of a rotating bed reactor for PFAS remediation

    University essay from Umeå universitet/Institutionen för fysik

    Author : Axel Martin; [2023]
    Keywords : Programming; automation; experimentation; optimization;

    Abstract : Properties such as being water and oil repellent and being heat resistant make per- and polyflouroalkyl substances (PFAS) useful in a wide range of products. Since they do not break down in the environment, PFAS pollution makes it way back into drinking water and seafood. READ MORE

  6. 20. Environmental Barrier Coatings to protect Ceramic Matrix Composites in next-generation jet engines

    University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

    Author : Shivang Parmar; [2023]
    Keywords : Environmental barrier coating; ceramic matric composite; atmospheric plasma spray; suspension plasma spray; thermal cyclic fatigue; Barriärbeläggning; keramisk komposit; atmosfärisk plasmasprutning; suspensionsplasmasprutning; termisk cyklisk utmattning;

    Abstract : Gas turbine engine efficiency needs to be raised in order to decrease fuel consumption, greenhouse gas emissions, and expenses. Efficiency may be improved in two ways: by reducing engine weight and raising intake temperatures. READ MORE
