  1. 1. Method to statistically secure field test results for rock drilling tools

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Frida Olander; [2023]
    Nyckelord :Statistics; Probability; Hypothesis test; Linear regression;

    Sammanfattning : The aim of this project is to find a statistical method that describes survival and outcome of a prototype drilling tool from several references and determine how many references are needed for a statistically secure result. The project also answers which variables that affects the outcome. LÄS MER

  3. 2. Inverkan av skruvars installation på fuktinträngning i trä

    Kandidat-uppsats, Lunds universitet/Byggproduktion

    Författare :Erik Arnebrant; [2023]
    Nyckelord :Moisture Content; Wood; Timber; Screws; Installation; Technology and Engineering;

    Sammanfattning : Wood and wood-based materials are common materials used in buildings, both in- and outdoors. However, wood is vulnerable to water and moisture which is why it is essential to keep it dry and prevent moisture from getting into the wood. LÄS MER

  4. 3. Assessment of a sediment management solution in a reservoir with a sluicing technique using a HEC-RAS 2D model : Case study of Andakílsá river in west Iceland

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Emilía Sól Gudgeirsdóttir; [2023]
    Nyckelord :SediCon Sluicer; Andakílsá Hydropower Station; HEC-RAS 2D Sediment modelling; Sustainable sediment management; SediCon Sluicer; Andakílsá vattenkraftverk; HEC-RAS 2D Sediment Modellering; Hållbar sedimenthantering;

    Sammanfattning : Sediment-related issues in reservoirs can often pose significant challenges to their operational effectiveness, sustainability, and environmental impact. Sustainable sediment management can help resolve these issues and extend the lifespan of dams. LÄS MER

  5. 4. An institutional weakness? – The participation of Chinese miners in Ghana’s artisanal and small-scale gold mining (ASGM) sector.

    Master-uppsats, Lunds universitet/Graduate School

    Författare :Enyam Joel Agbesinyale; [2023]
    Nyckelord :Chinese participation; ASGM; Institutional weakness; Rural transformation; Ghana; Social Sciences;

    Sammanfattning : This thesis addresses the ongoing debate on the involvement of Chinese nationals in Ghana's artisanal and small-scale gold mining (ASGM) sector. Despite the Minerals and Mining Law, Act 703 (2006) prohibiting foreigners from engaging in ASGM, it is reported that about 50,000 Chinese nationals have migrated to rural Ghana to engage in illegal mining activities.

  7. 5. Modelling the Occurrence and Fate of Microplastics Caused by Tyre Wear on Highway E18

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Aniruddha Kshirsagar; [2023]
    Nyckelord :Tyre Wear Plastics; stormwater system; Microplastics; settling; hetero-aggregation; modelling; Modellering; mikroplaster;

    Sammanfattning : The accumulation of microplastics (MPs) are a growing concern for the environment, the maximum contributor to the MP pollution is tyre wear particles or TWPs. TWPs can accumulate in the environment and remain there for long periods of time and hence have the ability to disrupt ecosystems. LÄS MER
