Type 2 diabetes (T2D) is a disease characterised by varying degrees of defect in insulin secretion and insulin sensitivity and associated with increased morbidity and mortality. Optimal glycaemic control reduces the progression of diabetic complications. Over time, there is a steady deterioration of glycaemic control that raises the need for effective therapy targeted at the underlying defects in
This dissertation considers two different aspects of health economics; (i) stated preference methods and (ii) empirical analyses of equity. The first essay deals with the issue of the choice of econometric models when analysing data from a closed-ended contingent valuation survey in health economics. The features of provision, either compulsory or voluntary, and the fact that certain individuals m
The environmental impacts of landfills are associated mainly with the emission of leachate and biogas. Sanitary landfilling aims to stabilize the landfill in a efficient and controlled way, so that the environmental impacts are minimized. When a sanitary landfill has attained its final storage quality, it can be integrated into the environment. Both the presence and the flux of water play key role
Abstract Habitat complexity is shown to be an important driver of invertebrate diversity on impacted coral reefs when the diversity supported by a comparative unit of habitat complexity is compared to that of a pristine coral reef. The more structurally complex pristine reef does not support the conventionally expected greatest amount of diversity, instead an upper limit threshold to habitat comp
Many of the coastal areas in Vietnam have elevations below one meter making them vulnerable to salt water intrusion, flooding, and erosion. The Red River Delta (RRD) located in northern Vietnam has suffered severe erosion along certain stretches of coastline during at least the last hundred years. At Hai Hau Beach in the RRD, a land area of 16 km in length and 2.5 km in width has been lost during
Solid oxide cells are an exciting technology for energy conversion. Fuel cells, based on solid oxide technology, convert hydrogen or hydrogen-rich fuels into electrical energy, with potential applications in stationary power generation. Conversely, solid oxide electrolysers convert electricity into chemical energy, thereby offering the potential to store energy from transient resources, such as wi
Induced polarization (IP) is an acknowledged method in ore exploration and can be applied to evaluate the metal content in dumps containing the residues of ore processing facilities. Existing models explain the relationships between ore content and grain size of the ore particles with IP parameters. However, the models assume full water saturation of the ore containing samples, which is often not
For several decades, a whole range of critical approaches emphasizing networks, flows and mobility have gained ground in social theory and slowly made its way into governmental practice. In few fields of study has the epistemological shift been as marked in both theory and practice as urban studies in general, and those interested in public space in particular. From Jane Jacobs ‘ballet’ of the str
Buildings from the so called Million programme has a high use of energy and in addition, there are many such houses. The need for them to be retrofitted is big. The City of Helsingborg has set a climate goal which states that the city in 2035 should be neutral in energy use which put a lot of pressure on the real estate owners in the city. All new buildings has to be energy efficient and older bui
Circular economy (CE) is still a nascent research field in the built environment, however, has gained traction in the last decade. Despite it being generally accepted that sustainability consists of three dimensions, namely, social, environmental, and economic, CE has been criticised for focusing on environmental and economic impact whilst neglecting the social aspect. Further, CE has been critici
Increasing demands to meet regulations on combustion emissions and their environmental impact, and the need to improve their efficiency in different applications, have been the centre of focus in research and industry for decades. Optical and laser diagnostics have been proven to be amongst the best available tools due to their remote nature and non-intrusiveness, high spatial and temporal resolut
High-order harmonic generation (HHG) supplies extreme ultraviolet (XUV) radiation with attosecond pulse duration for a wide variety of applications from fundamental research to industry. As HHG is a very inefficient process, enhancing the XUV flux is of great interest. Hereby, either the HHG process itself or the laser which is the primary driver of HHG can be optimized.Currently, the technology i
Popular Abstract in Swedish Svenska lägenhetshushåll genererar i snitt 2.8-3.4 kg matavfall per vecka. Allt fler svenska kommuner har under senare år valt att införa separat insamling och biologisk behandling av matavfall. Den främsta anledningen till detta var det miljömål som syftade till att 35 % av matavfallet från hushåll, restauranger och storkök enligt riksdagens miljömål skulle behandlas bAn increased understanding of the world’s limited resources and the negative environmental impacts connected to solid waste management has in recent years increased interest in separate collection and treatment of organic waste in many parts of the world. As an example, increased biological treatment of organic waste is an explicit goal within the Swedish national solid waste management strategy (
Lignin is found in all biomass and is an abundant natural source of aromatic compounds. It has the potential to serve as a renewable raw material for a variety of chemicals currently derived from fossil fuel sources such as muconic acid, an important platform chemical. Kraft lignin is a waste stream from the pulp and paper industry. Upon depolymerization of softwood-derived lignin, aromatic compou
Urbanisation is causing densification of cities and more and more facilities are being placed in the underground to utilise the urban space as efficiently as possible. Access to the underground is obtained by constructing vertical access shafts. By constructing the shaft with a circular plan geometry, an effective construction is obtained which can carry large earth pressure loads by utilising the
It is challenging for the food industry to deliver products that satisfy consumers changing desires and needs. Baobab is a fruit that holds potential for the development of trendy food products due to its rich nutritional profile and unique rheology. Unlike most fruits, it contains a dry pulp with a moisture content of 11-12 % (Phytotrade, 2008). Despite these features, baobab has been overlooked
A receiver that covers several RF bands requires multiple front-end filters which increases the cost in terms of components and/or board/silicon area. Front-end filters assist a receiver to withstand interference at multiples of its down-conversion frequency. Analog discrete-time filters have gained a lot of traction lately, mainly due to their promising architecture, achieving baseband filtering,
This thesis explores the integration of hydrogen and battery energy storage systems as a means to enhance the management of wind and solar power in the pursuit of a greener grid. The objective of the study is to identify the potential benefits and challenges associated with hybrid energy storage systems (HESS) and their role in renewable energy integration. The thesis begins with a literature rev
