  1. 1. Nonpoint source water pollution management : Monitoring, assessment and wetland treatment

    Author : Lorin Reinelt; Linköpings universitet; []

    Abstract : The management of nonpoint (diffuse) sources of-water pollution has received increased attention during the past decade. New techniques that aid in the identification and assessment of these diffuse sources can increase the chances for success of nonpoint source control efforts. READ MORE

  2. 2. Water-based Tape Casting of Ceramics and Fabrication of Ceramic Laminates

    Author : Annika Kristoffersson; Chalmers University of Technology; []
    Keywords : water-based tape casting; latex binders; high solids loading; silicon carbide; colloidal stability; polyelectrolyte dispersants; alumina; ceramic laminates; rheology;

    Abstract : The objective of the work presented in this dissertation has been twofold: to develop a water-based system for tape casting and to build laminar structures from the tapes. A set of requirements on the binder was specified and latexes were identified as suitable for water-based tape casting, mainly owing to their low viscosity and high polymeric content. READ MORE

  3. 3. Ecohydrologic impacts of dams : A global assessment

    Author : Catherine Reidy Liermann; Christer Nilsson; Angela Arthington; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; dam; reservoir; river regulation; flow alteration; fragmentation; freshwater biodiversity; Hydrology; Hydrologi;

    Abstract : This dissertation aims to improve our understanding of how dams and reservoirs impact freshwater systems worldwide. The following questions were addressed specifically: 1) what are the spatial patterns and magnitudes of flow regulation and channel fragmentation by dams globally; 2) how are dam impacts distributed biogeographically, and which are the biogeographic regions and taxa most threatened by dam impacts; and 3) how can climate change and dams be expected to interact in basins, and what management actions would mitigate adverse interactions? Results show that the majority of the world’s large river systems are fragmented and have their flow altered by dams. READ MORE

  4. 4. Quantification of Fat Content and Fatty Acid Composition Using Magnetic Resonance Imaging

    Author : Pernilla Peterson; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; fat quantification; water fat imaging; chemical shift; skeletal muscle; fat reference; bipolar gradient; fatty acid composition; relaxation;

    Abstract : In obesity and several other disease scenarios, the measurement of fat accumulation in various organs and tissues has become a sought-after technique in clinical diagnostics and research. Especially, quantitative and non-invasive techniques which also provide images of accumulated fat throughout the body would be valuable. READ MORE

  5. 5. Enhancing Tropospheric Humidity Data Records from Satellite Microwave and Radiosonde Sensors

    Author : Isaac Moradi; Chalmers University of Technology; []
    Keywords : CDR; climate; microwave; radiosonde; water vapor; remote sensing; antenna; homogenization; humidity; meteorology; troposphere; radio-frequency;

    Abstract : Water vapor is the most dominant greenhouse gas and plays a critical role in the climate by regulating the Earth's radiation budget and hydrological cycle. A comprehensive dataset is required to describe the temporal and spatial distribution of water vapor, evaluate the performance of climate and weather prediction models in terms of simulating tropospheric humidity, and understand the role of water vapor and its feedback in the climate system.
