  1. 1. Winter wheat exudates : Improving wheats resilience to drought

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Freja Haverland; [2024]
    Keywords : drought; PGPR; exudates; agriculture; food security;

    Abstract : Wheat (Triticum aestivum) is a crop that dominates the diets of about 35% of the world's human population. But wheat yields can be severely affected by drought. Therefore, in this experiment, root exudation of winter wheat was compared to find out how exudation changes during drought stress. READ MORE

  3. 2. Improving the temporal resolution of a microspectrometer for the study of the photophysics of enhanced green fluorescent protein

    University essay from KTH/Tillämpad fysik

    Author : Lukas Rane; [2021]
    Keywords : Biophysics; EGFP; Fluorescence; triplet state; Biofysik; EGFP; fluorescens; triplet tillstånd;

    Abstract : The use of fluorescent proteins as fluorescent markers has exploded over the last decades. In particular due to the development of advanced microscopy for live cell measurements, dynamic molecular studies down to single molecule levels and for superresolution microscopy. READ MORE

  4. 3. SOLAR ROOF - Roof potential investigation for installing PV system

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Forough Hosseini; Saba Salehi; [2020]
    Keywords : Solar roof; solar potential; PV system; Ventilation system; Photovoltaics; million-program buildings; Technology and Engineering;

    Abstract : By increasing the amount of CO2 emissions to the atmosphere because of using fossil fuel and the limitation of non-renewable energy sources, solar photovoltaics technology has been growing steadily and is thought to play an important role in the realm of future energies. The objective of this thesis is to investigate the potential of the rooftops for installing PV system on a small scale of 30 multifamily houses in Gothenburg divided into four categories of age, location, roof type, and ventilation system.

  5. 4. Photo-chemical reactivity of dissolved organic carbon in subarctic lakes from northern Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Hani Younes; [2020]
    Keywords : Photo-reactivity; DOM; subarctic lakes; EEM-PARAFAC. Brownification; Earth and Environmental Sciences;

    Abstract : Dissolved organic matter (DOM) is the major absorber of sunlight in most natural waters and a critical component of the carbon cycle in aquatic systems. The photochemical decomposition of DOM can have a significant impact on the landscape-atmosphere carbon exchange. READ MORE

  6. 5. Comparison of a hybrid ventilation system and a mechanical ventilation system with heat recovery through life cycle assessment : A case study of a modern Danish office building

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Josefine Nilsson Willkomm; [2020]
    Keywords : life cycle assessment; ventilation system; environmental impact; hybrid ventilation system; mechanical ventilation system with heat recovery; livscykelanalys; ventilationssystem; miljöpåverkan; ventilation; hybrid ventilationssystem; mekaniskt ventilationssystem med värmeåtervinning;

    Abstract : The building sector is responsible for 36% of the energy usage and 39 % of all CO2- emissions in European union (EU). Therefore, it is of great interest to investigate how the building sector can become more energy efficient and lower the environmental impact. READ MORE
