3. 27. Protection and treatment of hypothermia in prehospital trauma care : with emphasis on active warming

   Författare :Peter Lundgren; Ulf Björnstig; Peter Naredi; Tore Vikström; Anne Guttormsen; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hypothermia; kirurgi; Surgery;

   Sammanfattning : Background: In prehospital trauma care active warming is recommended to aid in protection from further cooling. However, scientific evidence of the effectiveness of active warming in a clinical setting is scarce. Also, evaluating the effectiveness of active warming, especially in harsh ambient conditions, by objective measures, is difficult. LÄS MER

4. 28. Changing Landscapes : An Environmental History of Chibuene, Southern Mozambique

   Författare :Anneli Ekblom; Paul Sinclair; Louis Scott; João Morais; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Archaeology; environmental history; archaeology; archaeobotany; paleoecology; vegetation history; pollen analysis; environmental management; environmental insecurity; resource utilisation; landscape; paleclimatology; trade; oral tradition; Mozambique; Vilanculos; Arkeologi; Archaeology subjects; Arkeologiämnen;

   Sammanfattning : This thesis analyses the dynamics of environmental change and its embeddedness in the long term interactions of social history and rainfall variability through the building of an environmental history of the Chibuene locality, the coastal plain of southern Mozambique, 5 km south of the town Vilanculos, from 400 AD to present day. Land-use practices over time are discussed on the basis of vegetation and land-use history based pollen analysis, charcoal influx and diatom analysis. LÄS MER

5. 29. Late Quaternary climate and environmental change in the summer rainfall region of South Africa : A study using trees and wetland peat cores as natural archives
