    Sammanfattning : Flooding is of great concern world-wide, causing damage to infrastructure, property and loss of life. Low-income countries, in particular, can be negatively affected by flood events due to their inherent vulnerabilities. Moreover, data to perform studies for flood risk management in low-income regions are often scarce or lacking sufficient quality. LÄS MER

  3. 2. Pre-hospital Barriers to Emergency Obstetric Care : Studies of Maternal Mortality and Near-miss in Bolivia and Guatemala

    Författare :Mattias Rööst; Birgitta Essén; Jerker Liljestrand; Veronique Filippi; Uppsala universitet; []
    Nyckelord :pre-hospital barriers; maternal mortality; near-miss; traditional birth attendants; social marginalization; Bolivia; Guatemala; barreras pre-hospitalarias; mortalidad materna; morbilidad obstétrica severa; parteras tradicionales; marginalización social; Bolivia; Guatemala; MEDICINE; MEDICIN; International Health; Internationell hälsa;

    Sammanfattning : Maternal mortality is a global health concern but inequalities in utilization of maternal health care are not clearly understood. Severe morbidity (near-miss) is receiving increased attention due to methodological difficulties in maternal mortality studies. LÄS MER

  4. 3. Environmental Effects of Agricultural Expansion in the Upper Amazon : A study of river basin geochemistry and hydrochemistry, and farmers' perceptions

    Författare :Lina Lindell; Mats Åström; Marianne Henningsson; Pasi Peltola; Tommy Claesson; Michael E McClain; Linnéuniversitetet; []
    Nyckelord :tropical humid forest; deforestation; land-use change; slash-and-burn agriculture; spatial variation; vertical distribution; multielement analysis; sustainable development; rural livelihoods; bosque húmedo tropical; deforestación; cambios de uso de la tierra; agricultura de tala y quema; variabilidad espacial; distribución vertical; análisis multielemental; desarrollo sostenible; cambio climático; sustentos rurales; Miljövetenskap; Environmental Science;

    Sammanfattning : In this thesis natural science is combined with environmental psychology in order to determine how deforestation and subsequent agricultural expansion in the Peruvian highland jungle has affected the natural environment and rural livelihoods. This region is part of one of the most biodiverse areas on Earth and is also exposed to high pressure from deforestation that threatens the ecosystems as well as the well-being of local populations.

  5. 4. Resource, Data and Application Management for Cloud Federations and Multi-Clouds

    Författare :Vamis Xhagjika; Leandro Navarro Moldes; Vladimir Vlassov; Gregory Chockler; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-Cloud; Geo-Distribution; Live Streaming; Locality optimisation; Multicast; Multi-Cloud Overlay; Cloud Federation; Web Real-time Communications; WebRTC-RTCWEB; Media Quality; Computer Science; Datalogi;

    Sammanfattning : Distributed Real-Time Media Processing refers to classes of highly distributed, delay no-tolerant applications that account for the majority of the data traffic generated in the world today. Real-Time audio/video conferencing and live content streaming are of particular research interests as technology forecasts predict video traffic surpassing every other type of data traffic in the world in the near future.

  7. 5. Hydro-Climatic Variability and Change in Central America : Supporting Risk Reduction Through Improved Analyses and Data

    Författare :Beatriz Quesada-Montano; Sven Halldin; Hugo G. Hidalgo; Ida K. Westerberg; Fredrik Wetterhall; Denis Hughes; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Central America; climate variability; disaster risk reduction; droughts; drought indices; floods; hydrological model; process constraints; statistical downscaling; uncertainty; ungauged basins; water resources.; Hydrology; Hydrologi;

    Sammanfattning : Floods and droughts are frequent in Central America and cause large social, economic and environmental impacts. A crucial step in disaster risk reduction is to have a good understanding of the causing mechanisms of extreme events and their spatio-temporal characteristics. LÄS MER
