  1. 1. Calibration and preparation of the data analysis of the DORN experiment on board the Chang'E 6 lunar mission.

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Íñigo de Loyola Chacartegui Rojo; [2023]
    Nyckelord :Radon; lunar mission; alpha spectrometry; space instrumentation; performance testing and validation;

    Sammanfattning : As part of the first agreement between the French (CNES) and the Chinese (CNSA) space agencies in terms of space exploration, the DORN instrument will fly on board the Chinese Chang'E 6 mission in 2024. It aims to measure the amount of Radon escaping from the lunar soil to better understand what governs the concentration of this noble gas which contributes to the endogenous origin of the lunar exosphere.

  3. 2. Municipal Narratives on Integration and Application of Green Infrastructure and Nature-based Solutions : A study of five municipalities in Stockholm County

    Master-uppsats, KTH/Urbana och regionala studier

    Författare :Louise Radon; [2023]
    Nyckelord :green infrastructure; nature-based solutions; municipal spatial planning; grön infrastruktur; naturbaserade lösningar; kommunal fysisk planering;

    Sammanfattning : Green terms to bring the greenery back to cities have frequently begun to be coined as a result of rapid urbanization. To emphasize the benefits of urban greenery, terms such as nature-based solutions (NbS) and green infrastructure (GI) have been raised in planning circles. LÄS MER

  4. 3. Well-posedness of a class of continuity equations posed in the space of time-dependent Radon measures

    Kandidat-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Författare :Erik Lieback; [2022]
    Nyckelord :Measure solutions; Population dynamics;

    Sammanfattning : We consider a class of partial differential equations whose solutions are elements of a space of measures. The motivation for modeling with measures is that sometimes selection-mutation models or models of for example population dynamics or opinion-formation are designed to describe not functions, but rather evolving distributions which can be described by measures.

  5. 4. Considerations and Development of a Ventilation on Demand System in Konsuln Mine

    Master-uppsats, Luleå tekniska universitet/Geoteknologi

    Författare :Seth Gyamfi; [2020]
    Nyckelord :Ventilation on demand VOD ; Swedish Occupational Health Safety OH S regulations; Threshold Limit Value TLV ; Ventilation model; Diesel; battery-powered; heat; and blast simulations; Contaminants;

    Sammanfattning : Ventilation on demand (VOD) concept has earned significant worldwide attention by several mining companies in recent years. It is a concept where airflow is provided only to areas that require ventilation. The implementation of the concept has resulted in significant savings in annual energy consumption and cost for several companies globally. LÄS MER

  7. 5. Marinduques sårbarhet för klimatförändringar och gruvbrytning : En litteraturstudie om påfrestningarna på den filippinska ön Marinduque

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

    Författare :Louise Radon; Matilda Samuelsson; [2020]
    Nyckelord :metal contamination; climate change; Marinduque; metallkontaminering; klimatförändringar; Marinduque;

    Sammanfattning : Små öar har kännetecken som gör dem särskilt sårbara för påfrestningar orsakade av klimatförändringar, och Marinduque är inget undantag. Marinduques miljö är fortfarande kontaminerad efter 27 års metallbrytning samt en av Filippinernas största gruvincidenter som ännu inte återställts. LÄS MER
