  1. 1. Thermal tolerance of native vs. invasive marine species at the Northern coast of Portugal

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sofie Michelsen; [2023]
    Keywords : Biodiversity; Climate change; Marine ecosystems; Marine heat waves; Intertidal environment; Invasive species; Macroalgae; Mussels; Sustainable Development; Thermal tolerance;

    Abstract : Two prominent factors posing a major threat to biodiversity in marine ecosystems are climate change and the establishment of invasive species, and the interaction between these two. Because of the upwelling of cold, nutrient-rich water, the coast of Portugal is a thermal refuge and distribution edge for cold-adapted species, making it a particularly important study area from a biodiversity point of view.

  3. 2. Fatigue Crack Growth Analysis in Python algorithm with Finite Element Methods : Numerical Simulation of Fatigue Crack Growth

    University essay from Karlstads universitet

    Author : Hasan Majid; [2022]
    Keywords : ;

    Abstract : The goal of this thesis was to construct and develop a python-based finite element computer program for the evaluation of fatigue crack growth rate in notched metallic rods. The simulation was done by implementing elastic stress theory and linear elastic fracture mechanics techniques. READ MORE

  4. 3. Life and fracture in very high cycle fatigue of a high strength steel

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Daniel Karlsson; [2021]
    Keywords : Very high cycle fatigue; VHCF; Fractography; Fine granular area; FGA; High strength tool steel; Ultrasonic testing equipment;

    Abstract : Classical fatigue models teach that there is an intrinsic fatigue limit for steels, representing a level of stress that is too low for regular crack growth where every cyclic load propagates a fatigue crack through the material. Modern application with extreme lifetimes has shown that fatigue will still take place in steels with stress levels well below the expected fatigue limit. READ MORE

  5. 4. Methods to assess nonfunctional overreaching in wrestlers : A literature review

    University essay from Umeå universitet/Idrottsmedicin

    Author : Anssi Sven-Erik Libäck; Katjaana Anni-Maria Kanninen; [2020]
    Keywords : Overtraining syndrome; maladaptation; performance decline; fatigue; wrestling;

    Abstract : Introduction Wrestling is a competitive and intermittent combat sport characterised mainly by strength components. Few researchers have examined nonfunctional overreaching in strength-based athletes, such as wrestlers, despite being prevalent. READ MORE

  6. 5. Visa vattnet! : gestaltning av Hospitalparken i Ulleråker

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Fredrika Thomasdotter; Helena Payne; [2018]
    Keywords : dagvattenhantering; öppen dagvattenhantering; dagvattendesign; försedimentationsdamm; svackdike; Hospitalparken; Ulleråker;

    Abstract : Vatten är ständigt närvarande både som resurs och problematik. Dagvatten definieras som allt ytligt regn- och smältvatten, och är något som förväntas öka volymmässigt med klimatförändringarna. READ MORE
