2. 1. Investigating Time-Varying Processes Using Seismicity and Time-Dependent Tomography

   Author : Alex Hobé; Ari Tryggvason; Olafur Gudmundsson; Roland Roberts; Nicholas Rawlinson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Time-Dependent Tomography; Joint Inversion; Geothermal Energy; Volcanotectonics; Seismic Unrest; Fagradalsfjall Eruption; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

   Abstract : Our global society is affected by, and makes use of, many time-varying processes. Processes related to geothermal energy and CO2 sequestration can help mitigate climate change and reduce the number of premature deaths (millions annually) due to air pollution from fossil fuels.

4. 2. Tree Rings as Sensitive Proxies of Past Climate Change

   Author : Håkan Grudd; Wibjörn Karlén; Brian Luckman; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tree ring; width; density; climate; temperature; change; variability; sensitivity; Torneträsk; Tornetrask; Sweden; Fennoscandia; explosive; volcanic; eruption; Santorini; Thera; subfossil; Fitzroya; Chile; Physical geography; Naturgeografi;

   Abstract : In the boreal forests of the Northern Hemisphere, time series of tree-ring width (TRW) and maximum density in the latewood (MXD) are highly correlated to local instrumental summer-temperature data and are thus widely used as proxies in high-resolution climate reconstructions. Hence, much of our present knowledge about climatic variability in the last millennium is based on tree-rings. READ MORE

5. 3. Distal movement of maxillary molars. Studies of efficiency and timing of treatment

   Author : Ingela Karlsson; Malmö högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Orthodontics; Distal molar movement;

   Abstract : Den vanligaste bettavvikelsen som behandlas bland barn och ungdomar är trångställning. När funktionellt och estetiskt störande trångställning i överkäken ska behandlas kan man vanligtvis ta bort tänder eller flytta de första stora kindtänderna (sexårständerna) bakåt för att sedan göra tandraden jämn.

6. 4. Health effects of air pollution in Iceland : respiratory health in volcanic environments

   Author : Hanne Krage Carlsen; Anna Oudin; Thorarinn Gislason; Kadri Meister; Bertil Forsberg; Gunilla Wieslander; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Respiratory health; air pollution; volcanic ash; epidemiology; hydrogen sulfide.; Epidemiology; epidemiologi; folkhälsa; Public health;

   Abstract : Air pollution has adverse effects on human health. The respiratory system is the most exposed and short-term changes in air pollution levels have been associated with worsening of asthma symptoms and increased rates of heart attacks and stroke. Air pollution in cities due to traffic is the major concern, as many people are exposed. READ MORE

7. 5. Event stratigraphy for the Last Glacial-Holocene transition in eastern middle Sweden

   Author : Jonas Björck; Michael J.C Walker; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Last Glacial-Holocene transition; event stratigraphy; eastern middle Sweden; pollen; plant macrofossils; marine calcareous fossils; microtephra; radiocarbon dating; clay varve chronology; GRIP; ice-core chronology; calendar year chronology; Preboreal oscillation; Yoldia Sea; Baltic Ice Lake; Quaternary Geology; kvartärgeologi;

   Abstract : This thesis outlines an event stratigraphy for the Last Glacial-Holocene transition in eastern middle Sweden. Events are short-lived occurrences that have left traces in the geological record and which, therefore, may be used for correlation and inter-regional comparisons. READ MORE
