  1. 1. Impact of Physical Object on Scaring of geese : with an agroecological approach towards the issue of geese as a pest in agriculture

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

    Författare :Elias Kvarnbäck; [2021]
    Nyckelord :geese; barnacle goose; greylag goose; large grazing birds; agroecological practices; flight initiation distance;

    Sammanfattning : The interactions and conflicts between geese and agricultural interests have risen in the last decades in Sweden. A range of measures are used by humans to disturb and scare geese with the goal to counteract crop damage. The hypothesis of this master thesis is that proximity to physical objects taller than 70 cm above the ground, e.g. LÄS MER

  3. 2. Super Duplex Stainless Steel Surfaces and their Effects on Marine Biofouling

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Adrian Falk; [2017]
    Nyckelord :Marin tillväxt; superduplex; bottenfärg; havstulpaner;

    Sammanfattning : Some of the world’s most ancient, but still viable, organisms have since the beginning of maritime caused problems for the industry. The problems affect both the longlivety and efficiency of ships which is caused by the mere presence of organisms attached to the ship hulls. LÄS MER

  4. 3. Paleoecology and sedimentology of the Upper Cretaceous (Campanian), marine strata at Åsen, Kristianstad Basin, Southern Sweden, Scania

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Sammanfattning : The Campanian marine strata from Åsen, north east part of the Kristianstad Basin (southern Sweden) contain a most diverse vertebrate and invertebrate marine fossil assemblages. A diverse fossil fauna was collected from Campanian deposits from a ca. 4.15m thick section during June-August 2010-2012. LÄS MER

  5. 4. Kemiskt försvar mot havstulpanskolonisering i marina svampdjur

    Kandidat-uppsats, Kemi; Tekniska högskolan

    Författare :Nina Bohlin; [2013]
    Nyckelord :Havstulpanslarver; ivermectin; spinosad; barettin; ellipsometri; påväxt; yttjocklek;

    Sammanfattning : The purpose of this project is to analyze and study the absorption of the substances ivermectin, spinosad and barettin to hydrophobic and hydrophilic surfaces, and to analyze and study if the barnacle larva are effected when they try to settle on the treated surface. Incubation tests with barnacle larva in Petri dishes were performed as well as absorption tests on hydrophobic and hydrophilic surfaces which were tested with ellipsometry. LÄS MER

    Sammanfattning : The world’s oceans are becoming more acid in a process called ocean acidification. The pH of the ocean have already decreased by 0.1 units from pre-industrial time until today. Scientists predict that by the year of 2100 the pH will decrease by as much as 0. LÄS MER
