1. 1. Exploring Typologies, Densities & Spatial Qualities : The Case of Low-Income Housing in South Africa

   Författare :Ana Mancheno Gren; Dick Urban Vestbro; Jörgen Andreasen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urban Form; House Types; Densities; Spatial Qualities; Low-Income Housing; South Africa; Urban Sprawl; Transect; Architecture and architectural conservation and restoration; Arkitektur och bebyggelsevård;

   Sammanfattning : This thesis focuses on problems that have resulted from the increasing pressure facing urban and suburban land use in South Africa, brought on by a number of different factors including the political and historical background of the country, as well as by rapid urbanization. The objective of this thesis is to present the perspectives applied in the analysis of the built environment in selected case studies, in which different theoretical and methodological approaches have been developed to address the research questions.

3. 2. Improving snow water equivalent estimates with ground penetrating radar by measuring on multiple channels

   Författare :Nils Sundström; Robert W. Jacobel; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

   Sammanfattning : Snow water equivalent (SWE) of a snowpack is often measured along well-chosen transects representative of an area of interest, such as a drainage basin, to capture spatial distribution of SWE, which is of great interest for many applications. For example, it is a useful input to the new generation of hydrological models used for snow melt run-off predictions. LÄS MER

4. 3. On methods for estimating oceanic flow

   Författare :Jenny A. U. Nilsson; Peter Lundberg; Peter Sigray; Bert Rudels; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ocean monitoring techniques; Barotropic flow; Baroclinic flow; Hydraulic theory; Baltic Sea; Bahía de Concepción; Oceanography; Oceanografi; Oceanography; oceanografi;

   Sammanfattning : The aim of this thesis was to estimate and possibly quantify ocean flow by utilizing conventional and novel observational methods as well as model results. Motionally induced voltages, from a cable-based observational system in the Baltic Sea, were analysed to determine their utility for ocean monitoring. LÄS MER

5. 4. Environmental occurrence and behaviour of the flame retardant decabromodiphenyl ethane

   Författare :Niklas Ricklund; Michael McLachlan; Amelie Kierkegaard; Adrian Covaci; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; brominated flame retardant; decabromodiphenyl ether; waste water treatment plant; mass balance; sludge; long range transport; atmospheric deposition; bioaccumulation; bioavailability; Persistent organic compounds; Persistenta organiska föreningar; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : The environmental occurrence and behaviour of the brominated flame retardant (BFR) decabromodiphenyl ethane (dbdpe) has only been studied to a limited extent. It is structurally similar to decabromodiphenyl ether (decaBDE), which makes it conceivable that dbdpe may also become an environmental contaminant of concern. LÄS MER

7. 5. Iodine Isotopes and their Species in Surface Water from the North Sea to the Northeastern Atlantic Ocean

   Författare :Peng He; Ala Aldahan; Per Roos; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; iodine isotopes; 129I; 127I; oceans; North Sea; speciation; Atlantic Ocean; English Channel; Celtic Sea; AMS; iodine chemistry; geochemistry; Earth Science with specialization in Environmental Analysis; Geovetenskap med inriktning mot miljöanalys;

   Sammanfattning : Huge amounts of anthropogenic 129I have been and still are released to the environment through liquid and gaseous discharges from the nuclear fuel reprocessing facilities worldwide and in particular the ones in Europe. Most of this 129I signal has been accumulated in the marine environment which plays a major role in the iodine natural pool. LÄS MER
