  1. 16. Simulated molecular adder circuits on a surface of DNA : Studying the scalability of surface chemical reaction network digital logic circuits

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jakob Arvidsson; [2023]
    Keywords : Surface chemical reaction networks; Molecular computing; DNA computing; Circuit simulation; Adders; Ytbundna kemiska reaktionsnätverk; Molekylär beräkning; DNA-beräkning; Kretssimulering; Additionskretsar;

    Abstract : The behavior of the Deoxyribonucleic Acid (DNA) molecule can be exploited to perform useful computation. It can also be ”programmed” using the language of Chemical Reaction Networks (CRNs). One specialized CRN construct is the Surface Chemical Reaction Network (SCRN). READ MORE

  3. 17. On The Evaluation of District Heating Load Predictions

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Herman Hansson; [2023]
    Keywords : Technology and Engineering;

    Abstract : District Heating is a technology with the potential to enable a fossil-free society. However, to realize this potential, some improvements need to be made in order to improve District Heating operation at large, decrease losses in the systems, and thus increase the competitiveness of District Heating as a technology.

  4. 18. Refining the particulate matter airway deposition arising from indoor cooking-related biomass combustion for children in the Haramaya district in Ethiopia

    University essay from Lunds universitet/Ergonomi och aerosolteknologi

    Author : Kasper Malmborn; [2023]
    Keywords : Air pollution exposure; charcoal; wood; animal dung; low-income setting epidemiology; Technology and Engineering;

    Abstract : Background: Air pollution, a global issue affecting millions of individuals, is linked to adverse health effects on the respiratory system, but also to e.g., cancer and cardiovascular ailments. In low-income countries, cooking is often conducted by biomass-combustion, causing women and children to be exposed to high levels of indoor air pollution. READ MORE

  5. 19. Solar Photovoltaic Thermal Collectors and Ground Source Heat Pumps for Commercial Buildings : Case study in Sweden

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

    Author : Doris Dijak; Elin Torstensson; [2023]
    Keywords : Ground Source Heat Pump; Photovoltaic Thermal Collectors; Borehole Thermal Energy Storage; Free Cooling.; Bergvärmepumpssystem; Termiska Solceller; Borrhålsbaserade Termiska Energilager; Frikyla.;

    Abstract : In order to reduce emissions from the building sector, which stands for than a fifth of the global energy consumption today, efficient and fossil free heating and cooling systems are of importance. This study investigates the combination of solar photovoltaic thermal collectors and ground source heat pump systems in order to regenerate energy to the ground in combination with free cooling.

  6. 20. Samband mellan fysisk aktivitet och sömn hos hundägare samt nattvila hos hund : effekter av ett gemensamt träningsprogram

    University essay from SLU/Dept. of Clinical Sciences; SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Moa Blomstedt; Emma Flyman; [2023]
    Keywords : aktivitetsmätare; fysisk aktivitet; hund; hundägare; samsovning; sömn; träningsprogram; vila;

    Abstract : Fysisk aktivitet är viktigt för att hund och hundägare ska må bra. Flera studier gjorda på människa och hund visar att en god fysisk aktivitet ger flera hälsofördelar. Inom humanstudier påvisas även att fysisk aktivitet ger en bättre sömn som även är en viktig del för måendet. READ MORE
