1. 11. Child health and acute respiratory infections in Ethiopia : epidemiology for prevention and control

   Författare :Lulu Muhe; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Epidemiology; acute respiratory infections; morbidity; mortality; infants; under-five children; determinants; intervention;

   Sammanfattning : This thesis is based on studies in Butajira district in the south central part of Ethiopia and one study in the Ethio-Swedish Children's Hospital in Addis Ababa. The Butajira project has a continuous demographic surveillance system, established in 1987 in a sample of 10 communities with a total baseline population of about 30,000. LÄS MER

3. 12. Infant and child mortality in Eritrea : levels, trends, and determinants

   Författare :Gebremariam Woldemicael; Basia Zaba; Stockholms universitet; []
   Nyckelord :demografi; Demography;

   Sammanfattning : This thesis has three main objectives: first, to estimate age-specific levels, age patterns and period trends in early mortality at national and sub-national levels in Eritrea; second, to investigate the major possible determinants of infant and child mortality; and third to discuss implications of the main findings for health policy and future research directions.The data used for this study come from the 1995 Eritrea Demographic and Health Survey of 5,469 households and 5,054 women in the reproductive age span.

4. 13. On urbanisation and birds : Insights from a molecular and physiological perspective

   Författare :Pablo Salmon; Evolutionär ekologi; []
   Nyckelord :Air Pollution; Antioxidants; Birds; great tit Parus major; Local adaptation; Nitrogen oxides; Oxidative stress; Parallel evolution; Survival; Telomere dynamics; Telomeres; Urbanisation;

   Sammanfattning : Urbanisation of natural habitats is rapidly intensifying and poses a potential global threat for wildlife. Thus, it is important to explore its impact on wildlife in order to understand the present and future threats and how resilient organisms are to them. LÄS MER

5. 14. Methods for Synchrophasor-Based Power SystemInstability Detection and HVDC Control

   Författare :Rujiroj Leelaruji; Luigi Vanfretti; Jean Mahseredjian; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wide-Area Monitoring Protection and Control Systems; Synchrophasor applications; Wide-Area Voltage Instability Detection; Wide-Area EarlyWarning Systems; Automatic Voltage Stabilizer;

   Sammanfattning : The recent availability Phasor Measurement Unit (PMU) functionalities in relay technology has opened up new opportunities for power system protection, allowing this microprocessor-based technology to be used beyond traditional protection purposes. This technology now also considers the computation and communication mechanisms that allow the transmission of synchronized phasor measurements. LÄS MER

7. 15. Bush Encroachment and the Role of Browse in Cattle Production : An ecological perspective from a bush encroached grazing system, Olifants Drift, Kgatleng District, Southeast Botswana

   Författare :Nkobi Moleele; Norman Owen-Smith; Stockholms universitet; []
   Nyckelord :savannas; bush encroachment; carrying capacity; browse; biomass; range degradation; colour infrared photographs; Landsat Thematic Mapper; mid infrared bands; tannins; toxins; aromatic substances; Dicrostachys cinerea; Grewia flava; NDVI; Olifants Drift; Botswana; naturgeografi; Physical Geography;

   Sammanfattning : The increase in density and cover of woody plant species is coincident with the introduction of cattle in southern Africa, and it is a wide spread phenomenon in the savannas of the world. The causes are little understood, but can only be speculated to be either anthropogenic or natural or a combination of both. LÄS MER
