The nature of solid-solid phase transformations has been a long-standing question spanning the fields of metallurgy and condensed-matter physics, with applications from metallic alloys and ceramics to modern shape-memory materials. In spite of the importance of solid-to-solid transformations in many areas of materials science and condensed-matter physics and the numerous experimental and theoretic
Partially premixed combustion has the potential of high efficiency and simultaneous low soot and NOx emissions. Running the engine in PPC mode with high octane number fuels has the advantage of a longer premix period of fuel and air which reduces soot emissions, even at higher loads. The problem is the ignitability at low load and idle operating conditions. The objective is to investigate the use
Several physical phenomena appear in anode-supported solid oxide fuel cells (SOFCs), such as multi-component gas species/charge flow, thermal energy and mass transfer. Meanwhile, generation and consumption of gas- and surface-phase species together with electric current production are involved at the active sites in different length scales. Therefore, various reactions in SOFCs are strongly couple
Background: This study has investigated the specific relationship between childhood adversities, individual trauma symptoms and the functions of non-suicidal self-injury (NSSI). The aim was to examine whether different self-reported adverse experiences and trauma symptoms predict the need to engage in NSSI, either to regulate emotions or to communicate with and influence others. Method: The partic
ColorFull, a C++ package for treating QCD color structure, is presented. ColorFull, which utilizes the trace basis approach, is intended for interfacing with event generators, but can also be used as a stand-alone package for squaring QCD amplitudes, calculating interferences, and describing the effect of gluon emission and gluon exchange.
Background: Over time, methods for the development of clinical decision support (CDS) systems have evolved from interpretable and easy-to-use scoring systems to very complex and non-interpretable mathematical models. In order to accomplish effective decision support, CDS systems should provide information on how the model arrives at a certain decision. To address the issue of incompatibility betwe
The aim of this research is evaluation of land suitability for urban land-use planning. Four factors and fourteen criteria were selected for suitability analysis and land-use planning. Factors and criteria were defined based on literature survey, experts' opinions, local contexts and availability of data. GIS-based Analytical Hierarchy Process (AHP) was used as a Multi-criteria Decision Making mod
An alternative concept for calibrating spectral image intensity ratios is described, which provides simple, but effective means of compensation for systematic errors, caused by nonlinearities in signal detection. The method relies on image segmentation by means of signal thresholds, where pixels are organized into different subgroups according to their corresponding signal count value. Instead of
A set of three dedicated triggers designed to detect long-lived neutral particles decaying throughout the ATLAS detector to a pair of hadronic jets is described. The efficiencies of the triggers for selecting displaced decays as a function of the decay position are presented for simulated events. The effect of pile-up interactions on the trigger efficiencies and the dependence of the trigger rate
The scope of this paper is to test the predictive capabilities of different evacuation modelling approaches to simulate tunnel fire evacuations. The study is based on the a priori modelling (prior to the experiments) vs a posteriori modelling (after the data collection stage) of a set of tunnel evacuation experiments performed in a tunnel in Stockholm, Sweden. Different degrees of modelling sophis
Popular Abstract in Swedish Mögel i byggnader är ett vanligt problem som kan orsaka en dålig innemiljö och påverka hälsan hos de personer som vistas i byggnaden. Kostnaderna för att åtgärda problemen kan vara omfattande. Att redan vid planeringsstadiet av en byggnad ta hänsyn till risker för mögelväxt kan leda till minskat antal mögelskador i framtiden och ett mer hållbart byggande. Mögelväxt är The susceptibility to mould growth varies between building materials. The factors that most affect mould growth, the relative humidity (RH) and temperature also vary in different parts of buildings. One way of preventing the growth of mould in buildings is therefore to choose building materials that can withstand the expected conditions. It is thus crucial that data are available to allow the corr
Single photons detected by the DELPHI experiment at LEP2 in the years 1997-2000 are reanalysed to investigate the existence of a single extra dimension in a modified ADD scenario with slightly warped large extra dimensions. The data collected at centre-of-mass energies between 180 and 209 GeV for an integrated luminosity of similar to 650 pb(-1) agree with the predictions of the Standard Model and
Using the ImmunoChip custom genotyping array, we analyzed 14,498 subjects with multiple sclerosis and 24,091 healthy controls for 161,311 autosomal variants and identified 135 potentially associated regions (P < 1.0 x 10(-4)). In a replication phase, we combined these data with previous genome-wide association study (GWAS) data from an independent 14,802 subjects with multiple sclerosis and 26,703
Topical negative pressure (TNP) treatment is a commonly used technique in the hospital care of acute or postoperative large, open wounds. In recent years the method has also been used to promote healing of so-called hard-to-heal ulcers, e.g. pressure ulcers, various leg ulcers, and diabetic foot ulcers. The SBU enquiry service has summarized the scientific literature on the clinical effects of TNP
Internal erosion is one of the major reasons for embankment dam failures. Despite this, the knowledge of the temporal development of internal erosion in full scale structures is limited. Detection of internal erosion is complicated using conventional methods, and new or improved methods are appreciated. Hallby was the first Swedish embankment to get a permanently installed monitoring system intend
2018 a new guide for designing retaining structures was published, which describes different methods for designing sheet pile walls. This master thesis aims at comparing and analysing these methods to find out how results obtained using them differ from each other and how well they correspond to measured values. The result shows that the methods in some aspects differ signicantly while in other as
DMSO är ett vanligt lösningsmedel för studier av syntetiska molekyler i biologiska system, bl.a. inom läkemedelsutveckling. Trots detta är lösningsmedlets interaktioner med dessa syntetiska molekyler och deras målprotein inte tillräckligt undersökta. DMSO kan påverka proteinerna struktur eller ha någon annan inverkan inbindningen. I detta arbete har denna möjliga effekt studerats för inbindningen DMSO sees common application as a solvent for studies of synthetic molecules in biological systems, in fields such as drug design. Despite this, the possibility and nature of solvent interactions with both synthetic ligand and their target macromolecules is widely unexamined. DMSO could potentially have significant effect on binding characteristics due to conformational changes of protein structur
