  1. 1. A Statistical Approach to Understand the Evolution of Exotic Butterfly Species

    University essay from KTH/Matematisk statistik

    Author : Elin Eliasson; Rebecka Haraldsson; [2023]
    Keywords : Phylogenetics; Tree reconstruction; COI barcoding; General Time Reversible Model; K80 Model; Evolution; Butterflies; Fylogenetik; Rekonstruktion av träd; COI barcoding; General Time Reversible modell; K80 modell; Evolution; Fjärilar;

    Abstract : The alarming rate at which we see the decline in biodiversity due to human activity has raised concerns about the well-being of our planet. Butterflies which serve as pollinators are an essential part of many ecosystems and sensitive indicators of environmental changes and can provide valuable insight into how ecosystems function and evolve.

  3. 2. Cognitive impairment in patients with generalized anxiety disorder : A systematic review and meta-analysis

    University essay from Örebro universitet/Institutionen för medicinska vetenskaper

    Author : Tea Hadzic; [2023]
    Keywords : ;

    Abstract : Background: Generalized anxiety disorder (GAD) is characterized by excessive anxiety and is associated with cognitive impairment (CoI) as part of the clinical picture. Long term anxiety can influence cognition negatively, yet there is a limited amount of reviews compiling present research on the association. READ MORE

  4. 3. Development of a DNA barcode for species identification of tuna

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Clara Nordquist; Jonathan Edwall; Leonora Eriksson; Nelly Mäkinen; Minna Sayehban; Matilda Styfberg; [2022]
    Keywords : Thunnini; D-loop; mitochondrial control region; CR; 16S; ATP8; COII; Cox2; CytB; COI; Cox1; ND2; NADH dehydrogenase 2;

    Abstract : Today, DNA-barcoding with the gene COI is regularly used in the identification of fish. However, this is not an adequate way of identifying species of tuna due to COI lacking sufficient interspecies divergence. This is problematic since fraud and mislabeling are a major concern within the fish and tuna industries. READ MORE

    Abstract : Multi-mesh gillnets are the most common gear in Swedish fish monitoring programs. The method works for many fish species but has limitations. READ MORE

  6. 5. The role of location of low inertia in power systems

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Bashar Alahmad; [2021]
    Keywords : Low inertia; Frequency stability; Rotor-angle stability; Nordic 32; Kundur; PowerFactory; Small-signal stability; Inter-area oscillation; Rate of Change of Frequency.;

    Abstract : The plans to reduce the energy-related greenhouse gas emissions stimulate the deployment of electronically interfaced renewable resources. The increased penetration of such intermittent sources together with phasing conventional power plants out and the installation of High Voltage Direct Current (HVDC) links for long-distance more efficient transmission, reduces the stored inertia in any electrical grid.
