  1. 1. Assessing the effect of Fusarium graminearum inoculation on the root structure of Swedish winter wheat cultivars (Triticum aestivum

    Master-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Fayez Altabbaa; [2022]
    Nyckelord :Fusarium graminearum; conidium suspension; hypha agar plug; root architecture traits; root cellar structure traits; shoot traits; genotypes;

    Sammanfattning : Several diseases attack the wheat crop and reduce the yield, such as root disease, which causes a tremendous loss in wheat production. Root rot has a variety of causal agents, such as nematodes, viruses, and bacteria, but the most common pathogens causing wheat root rot are oomycetes and fungi. LÄS MER

  3. 2. Ekonomisk driftoptimering av det termiska energisystemet på Karlstad centralsjukhus : Framtida driftrekommendationer baserat på linjärprogrammering

    Master-uppsats, Karlstads universitet

    Författare :Petter Mellander; [2022]
    Nyckelord :Linear programming; ground source cooling; ground source heat pump; district heating; heat pump; cooling machines; ground storage; borehole; Linjärprogrammering; frikyla; bergvärme; fjärrvärme; värmepump; kylmaskin; marklager; borrhål;

    Sammanfattning : Studien använder linjärprogrammering för att optimera driften av det termiska energisystemet på Karlstad centralsjukhus ur ett ekonomiskt perspektiv. Bakgrunden till studien är de höga elpriser som rådde under slutet av 2021 samt att det i dagsläget finns kunskapsluckor angående hur systemet bör köras optimalt. LÄS MER

  4. 3. Evaluation of selected parameters of Total Oxidisable Precursor Assay on per- and polyfluoroalkyl substances

    Magister-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Sofia Francois; [2021]
    Nyckelord :Per- and polyfluoroalkyl substances PFASs ; Total oxidisable precursor TOP assay; solidphase extraction SPE ; washing steps; PFAS precursor compounds.;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFASs) are man-made fluorinated compounds that havebeen detected in humans, the environment, and wildlife. The strong C-F bonds contribute tothe high thermal stability of some PFASs and make them extremely resistant to degradationunder normal environmental conditions. LÄS MER

  5. 4. Pearls as bycatch mitigation strategy for Harbour porpoise (Phoecena phoecena)

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Sara Gustafsson; [2020]
    Nyckelord :harbour porpoise; bycatch mitigation; acoustic reflector; pearl; gillnet; F-POD; click rate; click behaviour; inter-click-interval; terminal buzz; diel phase; GAM;

    Sammanfattning : One of the major threats to harbour porpoise population sustainability is thought to be the high incidence of bycatch specifically in gillnets. This study aims to examine the use of acrylic class pearls developed in an earlier study as acoustic reflectors on gillnets in an effort to increase their visibility to echolocating harbour porpoises in the lumpsucker fishery in Kattegatt.

  7. 5. The Moat of Finance : Does Complexity Reward the Private Investor?

    Kandidat-uppsats, KTH/Fastigheter och byggande

    Författare :Johan Svanberg; Daniel Max; [2019]
    Nyckelord :Price to Earning; Price to Book; Dividend Yield; Multi-ratio Strategies; Efficient Market Hypothesis; Modern Portfolio Theory; Excess Returns; Alpha and Stockholm Stock Market.;

    Sammanfattning : This paper evaluates the ability of single and multi-ratio investment strategies, such as P/E, P/B, Magic Formula and Piotroski F-score, to generate excess returns and positive alpha values on the Stockholm Stock Market. Performances of the strategies tested are compared to the Stockholm Stock Market as a whole, also known as the index “OMXSPI”. LÄS MER
