In this study, a three-dimensional calculation method has been developed to simulate and analyze steam reforming of natural gas, and the effects on various transport processes in a duct from a compact steam reformer. The reformer conditions such as the combined thermal boundary conditions on solid walls, mass balances associated with the reforming reactions and gas permeation to/from the porous ca
The idea for nature based research design emerged in preparation of a workshop and subsequent exhibition regarding minimal surfaces, supervised by Andreas Hopf, Senior Lecturer at Lund University School of Industrial Design, and supported by Prof. Dr. Konrad Polthier (Chair Mathematical Geometry Processing, FU Berlin) at the DESIGNMAI digital crafts event in Berlin in 2007, for which Swedish desig
House dusts, collected for detection of microorganisms in buildings, sometimes have to be stored before measurement. It is possible that continued growth of microorganisms in the stored samples will increase the levels of CFU, chemical marker, biomass etc. The aim of this investigation was to assess the influence of relative humidity on microbial growth in dust samples. We have exposed dust sample
Even though multisensory environments (MSE) incorporate artifacts and technology to provide sensory stimuli, most of these artifacts are non-interactive. Twenty-four children with profound developmental disabilities from three MSE institutions have been involved in a research study. A handful of interactive design artifacts, which have been developed as a tool for ideation and to enhance the use o
One problem with web servers is that they are sensitive to overload. The servers may become overloaded during temporary traffic peaks when more requests arrive than the server is designed for. Because overload usually occurs rather seldom, it is not economical to overprovision the servers for these traffic peaks, instead admission control mechanisms can be implemented in the servers. This pa per i
In spite of an Enterprise Systems Implementation Methodology's (ESIM's) potential and significance for Enterprise Systems implementation, little attention has been paid to its evolution in ES literature. Moreover, current studies reveal contradictory findings and provide a fragmented understanding. The purpose of this paper is to provide a framework underpinned by a morphogenetic approach for expl
The Sound Environment Center at Lund University has for over ten years hosted interdisciplinary research on sound environment issues promoting an exchange of ideas between researchers through research projects, interdisciplinary symposiums and publications. The center aims at developing a holistic view to a field that is scientifically fragmented. Ranging from acoustics, noise abatement and sounds
The Hessian fly, Mayetiola destructor Say (Diptera, Cecidomyiidae), is a pest of wheat and belongs to a group of gall-inducing herbivores. This species has a unique life history and several ecological features that differentiate it from other Diptera such as Drosophila melanogaster and blood-feeding mosquitoes. These features include a short, non-feeding adult life stage (1–2 days) and the u
This paper describes the involvement of end users in a project aimed to create a navigation aid for older persons who have memory decline, which affects navigation skills, and thus their independence. Interviews, focus groups with “stick man scenarios” and shorter usability tests seemed to work well. An extended test where the users themselves were expected to use the system independently was not
Rural law courts are sometimes believed to have contributed to juridical fragmentation, which led to coordination failures and, hence, to high transaction costs. We present a case study of the village law court of Mijnsheerenland, and pay particular attention to the question of whether non-residents expected villagers to have a 'home court' advantage. Our analysis of default risk premiums demanded
BACKGROUND: Two pathways are responsible for the majority of regulated protein catabolism in eukaryotic cells: the ubiquitin-proteasome system (UPS) and lysosomal self-degradation through autophagy. Both processes are necessary for cellular homeostasis by ensuring continuous turnover and quality control of most intracellular proteins. Recent studies established that both UPS and autophagy are capa
Follow-on pharmaceutical innovation occurring after the initial discovery of a drug active ingredient plays an important, but at times underappreciated, role in providing innovative solutions to compelling medical needs. Examples of follow-on innovation include new forms of a drug with improved safety-efficacy profiles, new formulations and dosages providing improved patient outcomes, and new meth
Carpal Tunnel Syndrome (CTS) is the most common compression neuropathy causing pain, impaired hand function and sick leave. CTS is usually diagnosed based on patient history and clinical tests. In some patients an additional ENeG is done to support the diagnosis. However, ENeG can show pathology in healthy people and show normal values in patients with overwhelming clinical signs of CTS. Tradition
This paper uses matched employer-employee data set for Sweden to study the relationship between firm age and wages, systematically addressing a variety of possible explanations for observing a firm age-wage effect. Results show considerable heterogeneity across years, along segments of the firm age distribution and across industries. For 1995, a positive relationship is found between firm age and
It is tractable to increase the torque for an HCCI engine and one way is to add a turbocharger. Operating in HCCI mode requires accurate control of the combustion phasing, CA50. The higher the engine torque, the narrower the CA50 window becomes where HCCI operation is maintained. As the CA50 varies stochastically between cycles this requires improved CA50 control for turbo HCCI engines. The main f
Denna avhandling undersöker vetenskapens roll i den politiska processens tidiga stadier. Detta görs genom att studera hur "geoengineering" kommer upp på den politiska agendan. Begreppet ”geoengineering” används även på svenska och beskriver en uppsättning idéer om hur man stabiliserar den globala temperaturen genom att ingripa i jordens miljösystem. Begreppet mötte stark skepsis i det vetenskaplig
Success factors are identified for residential fires. Success factors are defined as aspects resulting in a positive outcome if a fire occurs in a home environment. The factors could be linked to the individual persons as well as to the society. The success factors have been identified using cluster analysis of statistical information and using interviews with rescue services personnel. The typica
Eukaryotic cells contain numerous compartments, which have different protein constituents. Proteins are typically directed to compartments by short peptide sequences that act as targeting signals. Translocation to the proper compartment allows a protein to form the necessary interactions with its partners and take part in biological networks such as signalling and metabolic pathways. If a protein
