  1. 31. Digital mapping of techno-economic performance of a liquid-based solar photovoltaic/thermal (PVT) system over large geographical cities around the world

    Magister-uppsats, Högskolan Dalarna/Energiteknik

    Författare :Santhan Reddy Penaka; [2020]
    Nyckelord :PVT; Liquid-based; Techno-economic analysis; Digital mapping; Large geographical cities;

    Sammanfattning : Photovoltaic thermal (PVT) collectors are widely used to harness a large fraction of the solar spectrum to generate electricity and heat from a single collector. The circulation of the working medium will pass through the collector which cools down the PV cell temperature and also increases the water temperature, which will increase the electrical and thermal performance at the same time.

  3. 32. The digesta passage rate among dairy cows with different abilities to consume large quantities of roughage : its impact on the milk production, and the reliability of the chemical fibre marker

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Maria Elisabeth Eklund; [2020]
    Nyckelord :chemical markers; chromium; chromium mordanted fibre; cobalt; concen-trate level; EDTA; iNDF; mean re-tention time; ethylenediaminetetraacetic acid; forage consumption; indigestible neutral detergent fibre; liquid digesta phase; MRT; rumen evacuation; sol;

    Sammanfattning : The objectives of the present master thesis were to investigate the passage rate among lactating Holstein and Swedish red dairy cows to investigate the hypotheses of: 1) The cows’ individual total mean retention time (TMRT) has a negative relationship to the cows’ individual forage intake capacity. 2) A reduced TMRT contributes to a reduced feed efficiency, but a higher milk yield.

  4. 33. Development of a Novel Device for Optimal Sample Blood Volume Collection from Patients with Sepsis

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Rasmus Boltshauser; [2020]
    Nyckelord :blood volume sample collection; blood volume sample device; double diamond approach;

    Sammanfattning : When performing sepsis diagnosis, the most important preanalytical variable is blood volume. Too little blood increases the risk for false negatives whereas overfilling causes increased risk for false positives. LÄS MER

  5. 34. Vilka aspekter finns det att beakta kring gödselseparering och dess transporter?

    M1-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Emil Karlsson; Magnus Nyholm; [2020]
    Nyckelord :gödselseparation; fosfor; övergödning; transport och dess miljöpåverkan;

    Sammanfattning : I dagens jordbruk finns det en ojämn fördelning utav näringsämnena från den animaliska gödseln. De flesta djurgårdarna är belägna i skogs och mellanbygd där det oftast inte finns tillräckligt med spridningsareal. LÄS MER

  7. 35. Verification of HARMONIE-AROME, ECMWF-IFS and WRF: Visibility and Cloud Base Height

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Elin Kindlundh; [2020]
    Nyckelord :HARMONIE-AROME; ECMWF-IFS; WRF; verification; visibility; cloud base height; HARMONIE-AROME; ECMWF-IFS; WRF; verifikation; sikt; molnbashöjd;

    Sammanfattning : Visibility and cloud base height are two important parameters within aviation meteorology and verification of operational numerical weather prediction (NWP) models with regard to these two parameters is therefore important. Visibility is often parameterized through an extinction coefficient, which is dependent on for example liquid or ice water content, however it also depends on the humidity, precipitation intensity and particle concentration.
