  1. 1. Can spawning site temperature regimes cause spawning time divergence in sympatric whitefish ecotypes? : Comparison of two hypotheses

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

    Author : Joni Riihimaa; [2023]
    Keywords : Coregonus lavaretus; Hatching time; Spawning habitat; Spawning time; Temperature dependence;

    Abstract : The spawning time differs between sympatric ecotypes of lake-dwelling whitefish (Coregonus lavaretus) and this temporal divergence can be linked to the type of spawning habitat used (i.e., streams, littoral or profundal). READ MORE

  2. 2. Multi-environment Screening of Timothy (Phleum pratense) Breeding Material for Better Forage Yield in Sweden.

    University essay from SLU/Dept. of Plant Breeding (from 130101)

    Author : Ibrahim Issa; [2022]
    Keywords : Phleum pratense; Multi-Environment; Forage yield; Sweden; Genotype-by-environment interaction Swedish;

    Abstract : Timothy (Phleum pratense) is one of the most widely used forage crops in hay and pasture grass mixtures in Nordic countries; it’s also used in areas where it is one of the top forage crops harvested high yield, especially in boreal climates. There hasn’t been any large-scale breeding of Timothy to develop varieties that are adapted for Swedish climate and standards, which is surprising given that Timothy is the main forage crop used in Sweden.

  3. 3. The Factory of the Future: An analysis on buildings, HVAC, and heat recovery systems in order to reduce energy consumption

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Christina Naumburg; [2022]
    Keywords : HVAC; energy; consumption; electricity; industry; heat recovery; Technology and Engineering;

    Abstract : The industrial sector in Sweden accounted for 38 percent of the country’s total energy consumption in 2019. As the world’s focus has shifted drastically on energy consumption, the industry sector’s has as well due to energy initiatives and government-driven regulations. READ MORE

  4. 4. Normalization of Cooling Demand in Buildings, development, and evaluation of methods

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

    Author : Xingtong Wu; [2022]
    Keywords : ;

    Abstract : Because of the increasing demand for indoor thermal comfort and the better insulation performance of building envelopes, cooling demand is an increasingly important part of building energy consumption despite the cold climate in Stockholm. Finding a way to normalize cooling demand to climatic conditions will help better energy audits to improve the building performance to achieve energy-saving. READ MORE

  5. 5. Influence of Climate Change on Building Effluent Wastewater Temperature in Stockholm by 2040

    University essay from KTH/Energiteknik; KTH/Farkostteknik och Solidmekanik

    Author : Sorhenn Gourhand Martin; [2021]
    Keywords : ;

    Abstract : This report aims to give predictions of Stockholm’s region climate (especially temperature and precipitations) by 2040 and describe the consequences of possible climate changes on the building effluent water temperature and flowrate. First, I did an extensive review of the literature about climate change and climate prediction in Stockholm’s area in order to suggest probable climate scenarios for 2040, using climatic data from the reference period 1960-1990.
