The current research focuses in understanding how inlet pressure, EGR, combustion phasing, engine speed and pilot main ratio are affecting the main parameters of the combustion (e.g. efficiency, NOx, soot, maximum pressure rise rate) in the novel concept of injecting high octane number fuels in partially premixed combustion. The influence of the above mentioned parameters was studied by performing
Much scientific evidence indicates that the Earth's climate is changing and the world has become more concerned about the global climate. This has encouraged many countries to consider future clean power production with wind power taking an increasing part. In Sweden, the government declared the intention of generating 30 TWh/year from the wind by 2020 instead of 7.1 TWh/year achieved in 2012. Egy
Governance of common resources such as water calls for rethinking structure, legal frameworks and property rights. In order to promote the decentralization of water governance, Water User Associations (WUAs) were created in many countries, such as India and Turkey, to operate and maintain irrigation systems as well as take over the responsibility of water distribution among water users. Despite pr
This presentation discusses an ongoing research project that aims to collect data about the practice of information search. It seeks to learn more about different ways in which tourist information is collected at different stages of a journey. Speaking to tourism planners and reading tourism research, it seems as if the digitalization of information has completely changed tourists’ information sea
Increased awareness, interest and use of assistive technology (AT) presents substantial opportunities for many citizens to become, or continue being, meaningful participants in society. However, there is a significant shortfall between the need for and provision of AT, and this is patterned by a range of social, demographic and structural factors. To seize the opportunity that assistive technology
Background: Early cardiopulmonary resuscitation (CPR) and defibrillation with an Automated External Defibrillator (AED) increase survival from out-of-hospital cardiac arrest (OHCA). Although international guidelines recommend the use of AED registries to increase AED use, little is known about implementation. The aim of this paper is to describe the development of a national AED registry, to analy
Although border politics have been given much theoretical attention in recent years, empirical studies of identity construction among border police officers are less common. In 2014, a two-year collaborative project partly funded by the EU was initiated in order to increase international collaboration between border police officers in the Baltic Sea area. The participating organizations were borde
Highly oxygenated multifunctional compounds (HOMs) play a key role in new particle formation (NPF), but their quantitative roles in different environments of the globe have not been well studied yet. Frequent NPF events were observed at two flagship stations under different environmental conditions, i.e. a remote boreal forest site (SMEAR II) in Finland and a suburban site (SORPES) in polluted eas
For many polar organic micropollutants, biotransformation by activated sludge microorganisms is a major removal process during wastewater treatment. However, our current understanding of how wastewater treatment operations influence microbial communities and their micropollutant biotransformation potential is limited, leaving major parts of observed variability in biotransformation rates across tr
In this work we discuss a gradient plasticity formulation which relies on the introduction of higher-order gradient contributions as additional arguments of the free energy function. These gradients can be interpreted in terms of the local geometrically necessary dislocation density. This gives rise to physically well-motivated kinematic-type hardening models in contrast to purely phenomenological
The artificial replaced hip joint represents the major success story in orthopedic surgery in the twentieth century; there is much interest in extending research on hip joint even further. The stress distribution in the different bone tissues of a femur is significantly altered after an artificial replacement. Thus, there is a strong need to increase the prosthesis performance considering several
Laser-wakefield accelerators (LWFAs) are high acceleration-gradient plasma-based particle accelerators capable of producing ultra-relativistic electron beams. Within the strong focusing fields of the wakefield, accelerated electrons undergo betatron oscillations, emitting a bright pulse of X-rays with a micrometer-scale source size that may be used for imaging applications. Non-destructive X-ray p
Directed colloidal self-assembly at fluid interfaces can have a large impact in the fields of nanotechnology, materials, and biomedical sciences. The ability to control interfacial self-assembly relies on the fine interplay between bulk and surface interactions. Here, we investigate the interfacial assembly of thermoresponsive microgels and lipogels at the surface of giant unilamellar vesicles (GU
Funded by European Community and Swiss government research project AZEP (Advanced Zero Emission Power Plant), the project was carried out at the Department of Energy Sciences at Lund Faculty of Engineering (LTH). The project addressed the development of a specific, zero emissions, gas turbine-based, power generation process to reduce local and global emissions in a cost-effective way. In this proj
E-procurement — e-business mechanisms deployed on procurement — offers many recent and innovative methods that can improve procurement in different ways. The key challenge of e-procurement, however, is how to apply the various e-procurement applications in such a way that they improve the procurement practice and sourcing strategy of a company. There is a demand for an investigation that scrutiniz
This paper explores the use of spreadsheets in budgeting in order to explain how and why spreadsheets are used or not used in budgeting practice. Guided by modern budgeting research, budgeting is considered as a social phenomenon which requires flexibility for decision-making and integration for management control. Twenty-one interviews with business controllers in eleven leading for-profit organi
Abstract Regnell, Astrid: Att se stjärnor på ljusa dagen. Förvandling och försoning i August Strindbergs En blå bok. Seeing stars in broad daylight. Transformation and Reconciliation in August Strindberg’s Zones of the Spirit. In this thesis a pattern of coherence is explored in August Strindberg’s Zones of the Spirit (En blå bok) – a literary work consisting of a collection of short and quite div
A paradigm shift is emerging in higher education especially regarding how universities should address personalized and collaborative mobile learning. Experiences from three international benchmarking-projects through the European Association of Distance teaching Universities (EADTU), the European Centre for Strategic Management of Universities (ESMU) and the First dual mode benchmarking club on qu
Anaerobic digestion and the production of biogas can provide an efficient means of meeting energy needs locally and reducing organic loading due to untreated waste material in water recipients. Furthermore, residues after anaerobic digestion may be used as a fertilizer to improve the soil in many parts of the world. Most natural organic waste can be used in anaerobic digestion. In developing count
