  1. 1. The astronomical consequences of primordial black holes

    Master-uppsats, Lunds universitet/Astronomi

    Författare :Loke Lönnblad Ohlin; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In the radiation or early matter dominated eras of the Universe, there is a theoretical possibility for the formation of black holes (BHs). These primordial black holes (PBHs) have been thought of as a possible candidate for dark matter (DM), and an attractive one at that as it would explain DM using only baryonic physics. LÄS MER

  2. 2. A multi-criteria GIS analysis for siting of utility-scale photovoltaic solar plants in county Kilkenny, Ireland

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Ingrid Piirisaar; [2019]
    Nyckelord :Geography; GIS; MCDM; solar plants; site suitability; Ireland; Earth and Environmental Sciences;

    Sammanfattning : Renewable energy is the keyword for energy industry sector in the world today. Solar energy has a huge potential, able to fulfill increasing energy demand and growing its share of energy sector. Republic of Ireland has one of the lowest solar energy deployment rates in Europe, although climatic conditions have been proved to be acceptable. LÄS MER

  3. 3. Radiation exposure to personnel during CT procedures

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Henrik Berg; [2018]
    Nyckelord :CT; Scattered radiation; Cataract; Cancer; PCXMC; Dose;

    Sammanfattning : During X-ray examinations a large part of the radiation is scattered from the patient, contributing to larger radiation doses to medical staff operating inside the examination room. Ionizing radiation contributes to the risk of developing cancer and hereditary diseases but also to the risk of developing cataract. LÄS MER

  4. 4. Modellering av energisignatur för flerbostadshus : En studie över möjligheter och begränsningar med olika sätt att beräkna energianvändning, baserad på energianvändning i sex hus belägna i Linköping

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Max Wahlqvist; [2018]
    Nyckelord :Energy signature; Energisignatur; linjär regression; flerbostadshus; determinationskoefficienten; klimatförändringen;

    Sammanfattning : This thesis is conducted within the project of categorizing the building stock in Sweden, which is a part of the research program Spara and bevara initiated by the Swedish Energy Agency. Categorizing the building stock is done to find typical buildings of which to analyze for energy efficiency measures. LÄS MER
