1. 6. Road Design for Future Maintenance : Life-cycle Cost Analyses for Road Barriers

   Författare :Hawzheen Karim; Björn Birgisson; Ulf Isacsson; Rolf Magnusson; Robert Thomson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road maintenance; road management; road planning; road design; life-cycle cost; road barrier; guardrails; cable barrier; road traffic injuries; barrier collisions and barrier repair costs.; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; Vägprojektering för minskade drift- och underhållskostnader;

   Sammanfattning : The cost of a road construction over its service life is a function of design, quality of construction as well as maintenance strategies and operations. An optimal life-cycle cost for a road requires evaluations of the above mentioned components. LÄS MER

3. 7. Unsaturated Solute Transport in a Semiarid Catchment - Nonlinear Analyses and Modelling

   Författare :Pernilla Öhrström; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geografi; Hydrogeologi; teknisk geologi; unsaturated zone; Hydrogeology; geographical and geological engineering; solute transport; scaling; soils; semiarid regions; heterogeneity; preferential flow; fractals;

   Sammanfattning : Unsaturated solute transport is highly variable and therefore difficult to predict. In semi-arid areas, where water resources are limited, the presence of macropores is of great importance for crop production. The bromide ion (Br-) and dye tracers are useful for studies of water movement. LÄS MER

4. 8. Migration in Prehistory : DNA and stable isotope analyses of Swedish skeletal material

   Författare :Anna Linderholm; Kerstin Lidén; Oliver Craig; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Migration; ancient DNA; stable isotopes; δ13C; δ15N; δ34S; mtDNA; lactose tolerance; Neolithic; Pitted Ware culture; Funnel Beaker culture; Vikings; Öland; Rössberga; Birka; Björned; Archaeology; Arkeologi; Archaeological Science; laborativ arkeologi;

   Sammanfattning : The main aim of this thesis is to show how scientific methods may be used to look at migration in prehistory on the basis of archaeological material. The individuals examined represent the period 4 000 BC to 1 000 AD and have their geographical origins in various parts of Sweden.Ancient DNA analysis is employed in three cases. LÄS MER

5. 9. Attraction and repulsion : modelling interfirm interactions in geographical space

   Författare :Sergiy Protsiv; Handelshögskolan i Stockholm; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : More than three quarters of the world’s economic activity is concentrated in cities. But what drives people and firms to agglomerate in urban areas? Clearly, some places may offer inherent benefits due to the location itself, such as a mild climate or the presence of natural harbours, but that does not tell the whole story. LÄS MER

7. 10. Gendered routes and courses : The socio-spatial mobility of migrants in nineteenth-century Sundsvall, Sweden

   Författare :Lotta Vikström; Umeå universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; emancipation; gender; geographical mobility; illegitimacy; industrialization; life-course; migration; nineteenth century; social mobility; women; Sundsvall; Sweden; urbanization;

   Sammanfattning : This dissertation examines migrants during a time of large-scale socio-economic transformations. These changes were particularly evident in the nineteenth-century town of Sundsvall, Sweden, to which thousands of men and women moved. LÄS MER
