1. 26. Long-Term Simulation of Coastal Evolution

   Författare :Hoan Le Xuan; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tidal inlet; inlet shoal; sediment transport; spit growth; shoreline change; spit model; inlet model; mathematical model; numerical model; shoreline model;

   Sammanfattning : There is a strong relationship between regional sediment transport and the local processes at tidal inlets and around coastal structures. Many coastal projects require quantitative understanding of these processes and the interactions between them. LÄS MER

3. 27. Changing population distribution in Sweden : long term trends and contemporary tendencies

   Författare :Johan Håkansson; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Population distribution; redistribution; Sweden; geographical levels; concentration; dispersion; accessibility; migration; natural population change; age composition;

   Sammanfattning : The aim of the thesis is to describe and analyse the population redistribution in Sweden at different geographical levels from the beginning of the 19th century to the end of the 20th century. The analysis is approached in three different ways. First, the redistribution at different geographical levels is analysed (papers I and II). LÄS MER

4. 28. Long-term Effects of Opioids in the Treatment of Chronic Pain : Investigation of Problems and Hazards on Clinical, Biochemical, Cellular and Genetic Levels

   Författare :Annica Rhodin; Torsten Gordh; Fred Nyberg; Mats Stridsberg; Mats Enlund; Harald Breivik; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; opioid; chonic pain; long-term opioid treatment; Anaesthetics; Anestesiologi; Anestesiologi; Anaesthesiology;

   Sammanfattning : After two decades of liberal prescribing of opioids, there has been an increasing recognition of problems connected to the prolonged use of opioids for chronic pain. The aim of my thesis was to explore some consequences of long-term opioid treatment for chronic pain such as problematic opioid use, endocrine disorders, tolerance and genetic variations in pain and opioid response.

5. 29. Durability and Long-term Performance of Adhesively Bonded FRP/steel Joints

   Författare :Mohsen Heshmati; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FRP steel joints; durability; fibre reinforced polymer; cohesive zone modelling; long-term performance; adhesively bonded joints; moisture diffusion;

   Sammanfattning : Fibre reinforced polymer (FRP) composites offer excellent properties, such as high specific strength and stiffness, corrosion resistance and light weight. Over the past four decades, FRPs have been increasingly used for strengthening and repair of bridge structures, and more recently, in the manufacture of whole/hybrid FRP bridges. LÄS MER

7. 30. Cognitive training in young and old adults : Transfer, long-term effects, and predictors of gain

   Författare :Petra Sandberg; Anna Stigsdotter Neeyl; Michael Rönnlund; Boo Johansson; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cognitive training; aging; old adults; executive function; life-span; individual differences; episodic memory; inhibition; shifting; updating; cognitive control; strategy training; mnemonics; predictors; Psychology; psykologi;

   Sammanfattning : Aging, also in the absence of pathological conditions, is associated with cognitivedecline, especially in so called fluid abilities, such as episodic memory andexecutive functions. Due to an ongoing demographic shift, a larger part of thepopulation will reach higher ages, and more people will be affected by age-relatedcognitive decline. LÄS MER
