  1. 6. Process Models for CO2 Migration and Leakage : Gas Transport, Pore-Scale Displacement and Effects of Impurities

    Författare :Farzad Basirat; Auli Niemi; Karsten Jensen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geological Carbon Storage; CO2 leakage; Field experiment; Laboratory experiment design; Multi-phase flow; Heterogeneity; Wettability; Pore-scale modeling; Impurity gases; Hydrology; Hydrologi;

    Sammanfattning : Geological Carbon Storage (GCS) is considered as one of the key techniques to reduce the rate of atmospheric emissions of CO2 and thereby to contribute to controlling the global warming. A successful application of a GCS project requires the capability of the formation to trap CO2 for a long term. LÄS MER

  2. 7. Struggle for Mobility : Risk, hope and community of knowledge in Eritrean and Ethiopian migration pathways towards Sweden

    Författare :Tekalign Ayalew Mengiste; Erik Olsson; Shahram Khosravi; Ninna Nyberg Sørensen; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; refugee journey; irregular migration; vulnerability; hope; human smuggling; knowledge; community; mobility; migration infrastructure; diaspora; socialantropologi; Social Anthropology;

    Sammanfattning : On the basis of the ethnographic fieldwork conducted in Sweden, Italy, Sudan and Ethiopia during 2013–2015, this study examines the motivations, organizations and impact of overland migratory journeys from Ethiopia and Eritrea across the Sahara Desert and Mediterranean Sea to Sweden. The analysis involves the exploring of how migrants strive to prepare, manage and survive the multiple risks and structural barriers they encounter: the exits from Eritrea and Ethiopia, negotiations and contacts with various brokers and facilitators, organized crime and violence, restrictive border controls, passage through the Desert and high Sea and finally, ‘managing the asylum system in Sweden’.

  3. 8. Evolutionary dynamics of migration and breeding in wild birds: genetic architecture, sexual conflicts and evolutionary constraints

    Författare :Maja Tarka; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantitative genetics; heritability; intralocus sexual conflict; antagonistic selection; QTL; G-matrix; wing length; arrival date; migration; geolocator; bird; Acrocephalus arundinaceus;

    Sammanfattning : Our knowledge of the evolutionary potential of traits involved in different selective episodes, especially in natural populations, is still limited. This is true for questions such as the genetic basis and inheritance of traits, how natural and sexual selection acts on them, and how selective conflicts influence the evolutionary response to selection.

  4. 9. Leaving Home in a Peasant Society. Economic Fluctuations, Household Dynamics and Youth Migration in Southern Sweden, 1829-1866

    Författare :Martin Dribe; Ekonomisk-historiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic history; historical demography; economic stress; migration; family strategy; longitudinal analysis; leaving home; event-history analysis; Ekonomisk och social historia;

    Sammanfattning : This study deals with the process of children leaving home and its interactions with the household economy in preindustrial society. A theoretical model of leaving home is outlined and then analyzed multivariately, using a longitudinal micro-level dataset for a sample of parishes in western Scania, Sweden, for the period 1829-1866.

  5. 10. Contextualising a South African social innovation for maternal and child health to mothers with experiences of migration in Sweden

    Författare :Per Kåks; Mats Målqvist; Sibylle Herzig van Wees; Anna Bergström; Jenny McLeish; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Social innovation; peer support; migration; parenting; parents; children; health promotion; trust; mistrust; implementation; empowerment;

    Sammanfattning : Despite a universally accessible and high-quality welfare system, disparities in health and wellbeing persist between families who have migrated to Sweden and the native population. The South African Mentor Mother programme, a social innovation for maternal and child health among socially disadvantaged communities, was transferred and adapted to benefit mothers and pregnant women with experiences of migrating to Sweden.
