  1. 1. Prevalence of ctrA and crgA genes in non-meningococcal neisserial species colonising the upper respiratory tract among university students in Örebro

    University essay from Örebro universitet/Institutionen för medicinska vetenskaper

    Author : Magnus Klinteskog; [2021]
    Keywords : Neisseria; meningitidis; ctrA; crgA; carrier;

    Abstract : Introduction: A Neisseria meningitidis carrier study has been conducted among students at Örebro university in Sweden in 2018 and 2019. Pharyngeal samples were collected from 3489 students. PCR for the genes ctrA and crgA was run on all samples. The positive samples were then cultured on agar plates to find the N. READ MORE

  2. 2. Possibilities with Stirling Engine and High Temperature Thermal Energy Storage in Multi-Energy Carrier System : An analysis of key factors influencing techno-economic perspective of Stirling engine and high-temperature thermal energy storage

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Martin Myska; [2021]
    Keywords : Stirling engine; High-temperature thermal energy storage; Linear optimization; Photovoltaics; Time of Use; Renewable energy; Load shifting; Self-consumption; Power grid;

    Abstract : Small and medium-scale companies are trying to minimise their carbon footprint and improve their cash flow, renewable installations are increasing all over the Europe and are expected to do so in following years. However, their dependency on the weather cause pressure on matching the production with demand. READ MORE

  3. 3. LCA of Low-temperature District Heating Network Components

    University essay from Lunds universitet/Institutionen för Energivetenskaper

    Author : Nils Olsson; [2021]
    Keywords : District Heating; LCA; Life Cycle Assessment; Pipes; Environment; Technology and Engineering;

    Abstract : Following the development of new materials and the continuous technical progress made in the construction and energy industries, district heating as a concept finds itself on the brink of a generational shift. One of the pioneering projects leading the way is the creation of Brunnshög, an modern and sustainable district under construction in the north-eastern end of the city of Lund, Sweden. READ MORE

  4. 4. Optical characterisation of AAO/CsPbBr3 perovskite nanocomposites

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Klára Nováková; [2021]
    Keywords : perovskite; scintillator; optoelectronics; semiconductor; X-ray detection; Physics and Astronomy;

    Abstract : Direct bandgap metal lead halide perovskites offer promising optoelectronic properties desirable in a wide range of applications including photodetection. However, the incomplete and poor understanding of the photophysical processes taking place in these materials, along with their poor stability, is the bottleneck for optimisation and further development of metal halide perovskite devices.

  5. 5. Testosterons betydelse för hanhundens fertilitet : kan analys av dess serumkoncentration bidra till fertilitetsdiagnostik?

    University essay from SLU/Dept. of Clinical Sciences

    Author : Stina Wallander; [2021]
    Keywords : testosteron; SHBG; FAI; CPSE; spermier; fertilitet;

    Abstract : Vid avel av hundar är det viktigt med en god fruktsamhet för att få en bred avelsbas. För utvärdering av fertilitet hos handhudar används ofta analys av ejakulat. I denna studie analyseras även serumkoncentration av testosteron för att se om det är en koppling mellan den och spermakvaliteten eller en hanhunds fertilitet. READ MORE
