2. 1. Sea cages, seaweeds and seascapes : Causes and consequences of spatial links between aquaculture and ecosystems

   Author : Nils Hedberg; Tedengren Michael; Nils Kautsky; Barry Costa-Pierce; Stockholms universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Spatial links; Aquaculture; Coral Reefs; Seagrass; Seascape; marin ekotoxikologi; Marine Ecotoxicology;

   Abstract : Aquaculture is of growing importance in the global seafood production. The environmental impact of aquaculture will largely depend on the type of environment in which the aquaculture system is placed. READ MORE

4. 2. Lake Dissolved Organic Matter Quantity and Quality : Variability across Temporal and Spatial Scales

   Author : Roger André Müller; Gesa Weyhenmeyer; Emily Stanley; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; dissolved organic matter; organic carbon; CDOM; lakes; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

   Abstract : Surface waters receive large amounts of dissolved organic matter (DOM) via runoff from land. The DOM is rich in organic carbon that serves as an energy source for the aquatic biota. During uptake of this energy, aquatic organisms mineralize organic carbon. READ MORE

5. 3. Mapping social-ecological systems and human well-being : A spatial exploration of the links between people and the environment in South Africa

   Author : Maike Hamann; Reinette Biggs; Gretchen Daily; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Social-ecological; systems; ecosystem services; bundles; human well-being; mapping; South Africa; vetenskap om hållbar utveckling; Sustainability Science;

   Abstract : It has become increasingly clear that dealing with present day environmental crises requires a holistic view that takes into account the interactions of social and ecological factors across multiple spatial and temporal scales. An example of where this new paradigm is being operationalized is the study of social-ecological systems. READ MORE

6. 4. Interference-based scheduling in spatial reuse TDMA

   Author : Jimmi Grönkvist; Jens Zander; Anthony Ephremides; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

   Abstract : Spatial reuse TDMA has been proposed as an access scheme for multi-hop radio networks where real-time service guarantees are important. The idea is to allow several radio terminals to use the same time slot when possible. A time slot can be shared when the radio units are geographically separated such that small interference is obtained. READ MORE

7. 5. Diagenesis and Reservoir-Quality Evolution of Paralic, Shallow Marine and Fluvio-lacustrine Deposits : Links to Depositional Facies and Sequence Stratigraphy

   Author : Osama Ahmed Hlal; Sadoon Morad; Hans Annersten; J. Marcelo Ketzer; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sandstone; Diagenesis; paralic; shallow marine and fluvio-lacustrine; reservoir quality; sequence stratigraphy; Solid earth geology and petrology; Berggrundsgeologi och petrologi;

   Abstract : Linking diagenesis to depositional facies and sequence stratigraphy enables better prediction of spatial and temporal distribution of diagenetic alterations, and thus of evolution of reservoir quality in sandstones. This thesis demonstrates that employing this approach is possible because depositional facies and sequence stratigraphy can provide useful information on parameters controlling the near-surface diagenesis, such as changes in: (i) pore-water chemistry, (ii) residence time of sediments under certain geochemical conditions, (iii) detrital composition and proportion of extra- and intra-basinal grains, and (iv) types and amounts of organic matter.
