  1. 1. Spray Induced Gene Silencing in Phytophthora infestans : investigating exogenous dsRNA application for the control of potato late blight

    Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Poorva Sundararajan; [2024]
    Nyckelord :Phytophthora infestans; RNAi; potato late blight; gene silencing; SIGS;

    Sammanfattning : Phytophthora infestans is an oomycete pathogen and the causal agent of late blight disease in potato and tomato. Even today, it causes massive loss to crop and economy worldwide. Current disease control strategies include breeding for resistance and extensive fungicide spray. LÄS MER

  3. 2. Pheromone-based mating disruption to control Spodoptera frugiperda in Tanzania: Possibilites and Constraints for smallholders

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

    Författare :Thomas O'Malley; [2024]
    Nyckelord :pheromone; mating disruption; fall armyworm; Tanzania; smallholder; Spodeptera frugiperda; integrated pest; management;

    Sammanfattning : Despite a growing interest in the use of pheromones as a more sustainable form of pest control, their use remains unstudied in the smallholder context. This paper is one of the first to study their use by small scale Tanzanian maize farmers to control the invasive pest Spodoptera frugiperda (known as fall armyworm). LÄS MER

  4. 3. Independent validation of a system for real-time localization of the prostate during motion tracking radiotherapy

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen

    Författare :Klara Stefansson; [2024]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Intrafractional prostate motion during external beam radiotherapy of prostate tumors has been reported as a limiting factor in accurate treatment delivery. Technology for real-time image-guided radiotherapy has been introduced for tracking and for compensating prostate motion during treatment and could allow for reduced target margins. LÄS MER

  5. 4. Torkstress hos urbana träd i Göteborg: Effekter av låg vattentillgång under torkan 2018

    Kandidat-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Andrea Sartorius; [2023-10-27]
    Nyckelord :;

    Sammanfattning : During late spring and most of the summer in the year of 2018 the weather in Sweden was more extreme than normal, with high temperatures and few rainfalls. This resulted in a drought, of which the effects were noticed all over the country. One of the noticeable effects was an earlier leaf abscission from trees. LÄS MER

  7. 5. Evaluating aperture shape controller (ASC) in modulated radiation treatments

    Master-uppsats,

    Författare :Vilma Andrén Cederholm; [2023-09-28]
    Nyckelord :Medical physics;

    Sammanfattning : To decrease aperture complexity, the aperture shape controller (ASC) is a recently introduced function in Eclipse external beam planning (Varian Medical Systems, Palo Alto, USA). ASC works within the photon optimizer, minimizing distances between adjacent leaf tips of the MLC. LÄS MER
