  1. 21. Functional analysis of effectors from Blumeria graminis and their effect on the plant microbiome

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : Victor Olsson; [2022]
    Keywords : proteins; Heterologus protein expression; Effector proteins; Nicotiana benthamiana; Pichia pastoris; Blumeria graminis f.sp. tritici;

    Abstract : With an expected population of 10 billion by the next century, agricultural production has to increase at the same pace to match such demand. One of the main obstacles to achieving this are the pathogenic microorganisms that reduce food quality and yields every year. READ MORE

  3. 22. Heterogeneous catalytic reactions studied with transient gas supply and event-averaged ambient pressure x-ray photoelectron spectroscopy

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/NanoLund: Centre for Nanoscience

    Author : Qianhui Liu; [2022]
    Keywords : Ambient pressure x-ray photoelectron spectroscopy; Event-averaging; Pd 100 surface structure oscillation; Physics and Astronomy;

    Abstract : CO oxidation over Pd(100) is studied with ambient pressure x-ray photoelectron spectroscopy (APXPS). Cyclic gas composition pulsing of the CO:O2 ratio, combined with a new method using software based event-averaging by image recognition over many pulses, is used to improve the signal-to-noise ratio substantially.

  4. 23. Simulation of IB-LOCA in TRACE : A semi-blind study of numerical simulations compared to the PKL test facility

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Matilda Tiberg; [2022]
    Keywords : Pressurized Water Reactor; Safetey analysis; LOCA; Intermediate Break; PKL; TRACE; transient; thermal hydraulics;

    Abstract : This thesis studied the performance of the thermal hydraulic software TRACE applied on an intermediate sized break (IB) happening on the cold leg in a pressurized water reactor (PWR), causing a loss-of-coolant accident (LOCA). The same accident has previously been simulated in the PKL Test Facility, which is a scaled version of a PWR and is used to simulate transients stemming from different accidents. READ MORE

  5. 24. Analysis of Resin Impregnated Non-woven : In collaboration with Hitachi Energy

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Ahmed Abdulkareem Najm Al-Saedi; Anders Hedenfeldt; Andrea García; Anna-Karin Kron; Cornelia Bergström; Lova Källkvist; [2022]
    Keywords : resin impregnated non-woven; bushings; composite; resin impregnated paper; tensile; bending; permeability; mechanical properties;

    Abstract : High voltage bushings are the most critical components of power transformers. A common material used in bushings is resin impregnated paper (RIP). Hitachi Energy is investigating whether this can be replaced with a new material, resin impregnated non-woven (RIN). READ MORE

  6. 25. Mitigating SSCI in a hybrid wind and PV farm utilizing PV-STATCOM : A Swedish case study

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Isabelle Löfgren; [2022]
    Keywords : impedance analysis; PV-STATCOM; SSCI; SSO; SSR; sub-synchronous control interaction;

    Abstract : The share of electricity generation in the power system being based on power electronics is increasing, which will impact the system in different ways, such as an increased risk for undesired interactions. An example is doubly fed induction generator (DFIG) based windfarms which have been shown to present negative resistance in (parts of) the sub-synchronous range (i. READ MORE
