4. 3. Damage Assessment of the 2022 Tongatapu Tsunami : With Remote Sensing

   University essay from KTH/Geoinformatik

   Author : Milton Larsson; [2022]
   Keywords : remote sensing; land cover classification; Sentinel-1; Sentinel-2; change detection; change vector analysis;

   Abstract : The Island of Tongatapu, Tonga, was struck by a tsunami on January 15, 2022. Internet was cut off from the island, which made remote sensing a valuable tool for the assessment of damages. Through land cover classification, change vector analysis and log-ratio image differencing, damages caused by the tsunami were assessed remotely in this thesis. READ MORE

5. 4. Assessing the suitability of using Sentinel-1A SAR multi-temporal imagery to detect fallow periods between rice crops

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Lukasz Langowski; [2021]
   Keywords : Geography; Geographical Information System; GIS; Remote Sensing; Fallow; Detection; Sentinel-1A; Synthetic-aperture radar; SAR; Earth and Environmental Sciences;

   Abstract : Fallow, understood as a period where no crop is cultivated during a growing season, is an important crop management practice. Fallow plays an important role in pest and disease management, and monitoring the presence and duration of fallow can have implications for understanding the extent and effectiveness of this agricultural practice.

6. 5. Cytokine production in equine peripheral blood mononuclear cells induced by SvSXP, a Strongylus vulgaris excretory/secretory protein

   University essay from SLU/Dept. of Animal Breeding and Genetics

   Author : Cecilia Winkler; [2021]
   Keywords : Strongylus vulgaris; equine; cytokine; cyathostomins; vaccine; SvSXP;

   Abstract : The most pathogenic intestinal parasite in horses is Strongylus vulgaris (large bloodworm). When a horse becomes infected with S. vulgaris, the larva penetrates the intestinal wall and migrates through the horse's blood vessels. The parasite can cause serious injuries that can lead to severe colic and, in the worst case, death. READ MORE
