1. 21. Improved methods and practices in life cycle assessment of wastewater and sludge management

   Författare :Sara Heimersson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater treatment; Life cycle assessment; decision basis; biosolids; sewage sludge; environmental impact;

   Sammanfattning : Large amounts of municipal and industrial wastewater are treated each year in order to prevent negative consequences to human health and the environment. The treatment processes, directly or indirectly, give rise to environmental impact, but also offer several possibilities to recover resources. LÄS MER

3. 22. Navigating towards environmental impact assessment of shipping

   Författare :Anna Lunde Hermansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; DAPSIR; scrubbers; metals; polycyclic aromatic hydrocarbons; marine environment; ship pollution;

   Sammanfattning : The shipping sector exert multiple pressures on the environment, affecting climate change, human health and the marine environment. From a policy perspective, shipping is usually assessed based on the emissions to air (e.g. LÄS MER

4. 23. Quantitative cardiac 15O-water PET : Assessment of left-ventricular function, remodeling, and impact of patient motion

   Författare :Jonny Nordström; Mark Lubberink; Jens Sörensen; Hendrik J Harms; Stephan Nekolla; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; positron emission tomography PET ; 15O-water; myocardial blood flow; cardiac remodeling; patient motion;

   Sammanfattning : International guidelines advocate the use of noninvasive cardiac imaging as the initial diagnostic test for coronary artery disease, the global leading cause of death according to the world health organization. Within the wide spectrum of cardiac imaging, 15O-water PET is the gold standard for noninvasive quantification of myocardial blood flow (MBF). LÄS MER

5. 24. Gamma Spectroscopy and Gamma Emission Tomography for Fuel Performance Characterization of Irradiated Nuclear Fuel Assemblies

   Författare :Scott Holcombe; Staffan Jacobsson Svärd; Hans-Urs Zwicky; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear fuel performance; Nuclear fuel assemblies; Gamma emission tomography; Gamma spectroscopy;

   Sammanfattning : Gamma spectroscopy and gamma emission tomography are two non-destructive measurement techniques for assessing the performance of nuclear fuel which have been investigated in this thesis for existing and novel applications through theoretical studies and experimental demonstrations. For assessment of individual fuel rods using gamma spectroscopy, fuel assemblies are dismantled so that the fuel rods may be measured separately, which is time-consuming and may cause damage to the fuel.

7. 25. Electrification in Process Industry - The Role of Process Integration and Future Energy Market Conditions

   Författare :Holger Wiertzema; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrification; bottom-up assessment; energy-intensive process industries; oxo synthesis; oil refining; energy market scenarios; techno-economic assessment; chemical industry;

   Sammanfattning : Electrification of industrial processes is a frequently discussed strategy to reduce greenhouse gas emissions from energy-intensive process industries and is highlighted in many roadmap studies. Electricity is a versatile energy carrier that enables a broad variety of options in which existing process unit operations are replaced with electricity-driven alternatives. LÄS MER
