    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Johannes Ekman; [2021]
    Keywords : calorimetry; calorimeter; System 251; temperature evolution; spent nuclear fuel; SNF; MATLAB; SERPENT2; Clab; nuclear decay heat; calibration measurements; thermodynamic model; gamma escape fraction; mass correction; calibration measurements; electric heater; three component system; system of ordinary differential equations; eigenvalues; eigenvalue estimation; temperature increase method; polynomial approximation of mass correction; sensitivity of mass correction; calorimeter heat capacity; mass correction uncertainty; calorimeter calibration curve; monoenergetic gamma spectrum; curve fitting of temperature as function of time;

    Abstract : It is important to know the heat generated due to nuclear decay in the final repository for spent nuclear fuel. In Sweden, the heating powers generated in spent nuclear fuels are currently measured in the calorimeter System 251 at the Clab facility, Oskarshamn. READ MORE

  3. 2. Tänk utanför boxen : en undersökning om hur tävlingshästar inom travsporten hålls, samt travhästhållares attityder till grupphållen lösdrift och investering i mekaniserade lösdriftssystem

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Elin Saloniemi; [2021]
    Keywords : loose housing; trotter; natural behaviour; welfare;

    Abstract : The aim of this study was to examine how racehorses in harness racing in Sweden were housed and trainers and horse owners' attitudes towards free-range housing and active stable system. A survey was sent out and gathered 251 answers from trainers and horse owners. 53 % housed their horses in boxstalls and 41 % in free-range housing. READ MORE

  4. 3. Future climate resilience of energy-efficient retrofit projects in central Europe

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

    Abstract : This study assesses the performance of buildings affected by climate change under future climate predictions for three time-periods until the end of the 21st century. Objects studied are residential multi-storey buildings, originally built before 1970 and retrofitted during the last decade. READ MORE

  5. 4. Electrochemical microsensor with in-situ fabricated Ag/AgCl reference electrode for high-pressure microfluidics

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Simon Södergren; [2017]
    Keywords : high pressure microfluidics; electrochemical microsensor; Ag AgCl reference electrode; Pt black;

    Abstract : Electroanalysis offers cheap and selective analysis of interesting solutions. However, one of the most common drawbacks is the accessibility for electrochemical sensing. By using high-pressure microfluidics with an integrated three-electrode system, new possibilities open for increased accessibility. READ MORE
