  1. 1. NDVI time series analysis for desert locust outbreak detection and quantification analysis of its impact on vegetation productivity of Sahel

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Evangelos Oikonomopoulos; [2020]
    Keywords : Physical Geography and Ecosystem Analysis; Primary Productivity; Desert Locust; NDVI; Time Series Analysis; Outbreak Detection; Food Security; Sahel; Insect Disturbances; GEM; Earth and Environmental Sciences;

    Abstract : It has been shown that the semi-arid environment of the Sahelian belt plays an important role in the global carbon uptake as the fluctuation of its primary productivity can be determinant for the global carbon uptake. The insect Schistocerca gregaria commonly known as the desert locust is a disturbance factor that can affect the vegetation productivity for consecutive seasons. READ MORE

  2. 2. Toxin production among epidemic Clostridioides difficile PCR ribotypes in Sweden

    University essay from Örebro universitet/Institutionen för medicinska vetenskaper

    Author : Hanna Berghamre; [2020]
    Keywords : ;

    Abstract : Introduction Clostridioides difficile infection (CDI) is the main cause of antibiotic microflora triggered enteritis.

  3. 3. Optimization of a multiplex ARMS-PCR for detection of the primary mutations causing Leber’s hereditary optic neuropath

    University essay from Uppsala universitet/Institutionen för kvinnors och barns hälsa

    Author : Klara Jäder; [2020]
    Keywords : Allele-specific PCR; LHON; Multiplex Polymerase Chain Reaction; mitochondrial DNA; single nucleotide polymorphism;

    Abstract : Leber’s hereditary optic neuropathy (LHON) is a genetic disease that causes the patients to become blind, first in one eye and then the other, around the ages of 10-75 years. The disease is caused by mutations in the mitochondrial DNA, which disturbs the respiratory chain leading to the deterioration of the retinal ganglion cells. READ MORE

  4. 4. Detecting bark beetle damage with Sentinel-2 multi-temporal data in Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Shuo Yang; [2019]
    Keywords : Physical Geography and Ecosystem Analysis; Remote Sensing; Bark Beetle; Insect Detection; Sentinel-2; Forest Health; Maximum Likelihood; Random Forest; Spectral Signature; Vegetation Indices; Earth and Environmental Sciences;

    Abstract : The European spruce bark beetle is considered as one of the most destructive forest insects to Norway spruce trees in Europe. Climate change may increase the frequency and intensity of bark beetle outbreaks. It is therefore of vital importance to detect the bark beetle outbreaks and take it under control to prevent further damages. READ MORE

  5. 5. Diversity of barley yellow dwarf-associated viruses in winter cereals of Southern Sweden

    University essay from SLU/Dept. Of Plant Biology

    Author : Marcelle Lauren Johnson; [2019]
    Keywords : barley; BYDV; luteovirus; polerovirus; Skåne; wheat;

    Abstract : Barley yellow dwarf virus (BYDV) is a widespread complex of virus species of cereal crops in the world, known to infect both wild and cultivated plants of the family Poaceae, having the effect of yield reductions and subsequently large economic losses to farmers. Barley yellow dwarf disease (BYD) is a result of infection from BYDV species (genus: Luteovirus) and cereal yellow dwarf virus (CYDV; genus: Polerovirus). READ MORE
