  1. 31. A Numerical Analysis on the Effects of Using CO2 as a Driving Fluid for a Geothermal Plant

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : David Bennich; [2020]
    Keywords : reinjection; two-phase flow; geothermal energy; CO2 sequestration; iTOUGH2; ECO2N; återinjektion; tvåfasflöde; geotermisk energi; koldioxidlagring; iTOUGH2; ECO2N;

    Abstract : To limit the effect of global warming society needs clean energy sources and to reduce emissions of greenhouse gases into the atmosphere. By combining carbon capture and storage technologies together with geothermal power production it is possible to gain fossil free energy while potentially storing CO2 at the same time. READ MORE

  3. 32. Järnstatus och rutiner för järnsupplementering till svenska smågrisar

    University essay from SLU/Dept. of Clinical Sciences

    Author : Amanda Bajraszewski; [2020]
    Keywords : smågris; järnstatus; järnsupplementering; hemoglobin; järnbristanemi; IDA;

    Abstract : Otillräckligt järnintag hos diande smågrisar resulterar snabbt i järnbrist och vidare järnbristanemi (eng. iron-deficiency anemia, IDA). IDA utgör ett allvarligt hälsoproblem hos våra domesticerade smågrisar, och leder till lägre tillväxt, mindre motståndskraft mot infektiösa sjukdomar och i värsta fall en ökad smågrisdödlighet.

  4. 33. Epidemiological aspects of infectious salmon anemia

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Karl Mård; [2019]
    Keywords : Infektiös laxanemi; ILA; epidemiologi;

    Abstract : Infectious salmon anemia is an orthomyxyviral disease posing a serious challenge to the aquaculture of atlantic salmon (Salmo salar). The virus causes severe disease resulting in high moratlity and significant costs to the industry. READ MORE

  5. 34. Investigation of the role of insulin receptor genes in wing polyphenism using gene knockdown and differential gene expression analysis in the non-model organism Gerris buenoi

    University essay from Uppsala universitet/Institutionen för ekologi och genetik

    Author : Sofia Iggström; [2019]
    Keywords : Phenotypic plasticity; RNAi; RT-qPCR; wing polyphenism; water striders;

    Abstract : Wing polyphenism is a type of phenotypic plasticity present in several insect species whereby a genotype have the ability to develop alternative wing morphs when exposed to different environmental cues. One organism demonstrating a clear case of wing polyphenism is the water strider species, Gerris buenoi, which develop long- or short wings depending on exposure to different photoperiods (the time the organism is exposed to light during a 24 h period).

  6. 35. Modelling of high-pressure fuel system for controller development

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Eric Pettersson; [2019]
    Keywords : Common-Rail Direct Injection; fuel system; water hammer; pressure oscillations; physical modelling; state-space representation;

    Abstract : This master thesis treats the modelling of a common-rail direct fuel injection system where pressure generation is decoupled from the injection process. It has been shown that the fuel pressure plays a vital role for the general performance of the engine, affecting both emissions and efficiency, and it is carefully regulated to achieve optimal performance at different operating points.
