    Abstract : With the Paris agreement calling to limit global warming to 2°C below pre-industrial levels, with further efforts to ensure it stays below 1.5°C, the Finnish government passed the Lakihiilen energiakäytön kieltämisestä (416/2019), i.e. READ MORE

  3. 22. Groundwater flooding in a Moldovan limestone mine : An investigation into the limestone aquifer in Chisinau andsustainable solutions to mine dewatering

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Erik Tobin; [2022]
    Keywords : groundwater; hydrogeology; limestone; mine; Moldova; Chisinau; grundvatten; hydrogeologi; kalksten; gruva; Moldavien; Chisinau;

    Abstract : This work aimed to investigate the groundwater situation in and around Mina din Chisinau, an underground limestone mine in Chisinau, Moldova, in order to contribute to a sustainable solution to its flooding problem. Work on-site was done including visits inside the mine, to points of hydrogeological relevance to the mine, well inventories/search, and an attempt at an infiltration test. READ MORE

  4. 23. Hydraulic Modeling and Quantitative Microbial Risk Assessment of Intrusionin Water Distribution Networks Under Sustained Low-Pressure Situations

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Maryam Shakibi; [2022]
    Keywords : drinking water distribution network; EPANET; hydraulic modelling; low pressure; pathogen intrusion; Quantitative Microbial Risk Assessment QMRA ; distributionsnät för dricksvatten; EPANET; hydraulisk modellering; lågtryck; patogen inläckage; Kvantitativ mikrobiell riskbedömning QMRA ;

    Abstract : Drinking water systems aim to remove, reduce, and prevent microbial contamination in water by usingmultiple barriers from catchments to consumers. Water distribution networks are vulnerable tocontamination from external sources if they lose their physical or hydraulic integrity. READ MORE

  5. 24. Modelling of liquid leakage with ASTEC in a severe accident of a PWR

    University essay from KTH/Fysik

    Author : Thomas Begey; [2022]
    Keywords : Nuclear Physics; Modelling; Iodine Chemstry; Nuclear Safety; Kärnfysik; modellering; jodkemi; kärnsäkerhet;

    Abstract : In a nuclear reactor, in case of a severe accident occurs, backup circuits are usedlike SIS and CSS, flooding the reactor with water. This might lead to many liquidleakages outside the reactor containment building. READ MORE

  6. 25. Carbon dioxide-based pump system for portable HPLC equipment

    University essay from Uppsala universitet/Mikrosystemteknik
