Some problems in mechanics, e.g. in bearing simulation, contain subsystems that are conservative as well as weakly dissipative subsystems. Our experience is that geometric integration methods are often superior for such systems, as long as the dissipation is weak. Here we develop adaptive methods for dissipative perturbations of Hamiltonian systems. The methods are "geometric" in the sense that th
This engineering design guideline is intended for wood in outdoor above ground applications, i.e. use class 3 according to EN 335. It is based on a prescribed limit state for onset of decay during a reference service life of 30 years. Onset of decay is defined as a state of fungal attack according to rating 1 in EN 252. The approach is to determine the climate exposure as a function of geographica
This is an attempt to write a popular book on mysticism, as requested by one of the largest publishers in Sweden (Natur och Kultur). Twelve mystics, representing Judaism, Christianity, and Islam, met in Andalusia (Córdoba) in order to discuss how spiritual leaders could contribute to increasing understanding between different cultures. When discussing their concept of God, view of man, mystical te
Popular Abstract in Swedish En fråga om liv och hälsa Livstillfredsställelse, personlighet och mortalitet i två äldre populationer Enligt en rapport från FN (2001) kan vi under de kommande 50 åren förvänta oss att andelen äldre över 60 år kommer att fördubblas. Ny och förbättrad teknik, medicinsk kunskap och behandling har utvecklats, vilket innebär att vi i dag överlever i större utsträckning dThe aims of the present thesis were to explore and describe elderly people’s morbidity and experience of symptoms in relation to life satisfaction, personality and mortality. (I, II and III) To learn from the individuals who have high life satisfaction in spite of the fact that they have concurrent medical diagnoses and conditions. (I and III) To reason how positive factors and strengths might hel
This chapter illustrates the intimate connection between creativity and learning in music making and it is suggested that agentive learning across the individual and collective may be studied as expansive learning. By drawing on empirical data from instrumental vocal tuition and professional organ improvisation, it is discussed how individual experiences of tensions and problems in artistic work m
During Subzero project there were observed some differences between different manikins. In order to study the differences closer complementary measurements were carried out on 2 manikins representing male and female body shapes. Comparison was carried out based on: • tight versus loose clothing; • serial versus parallel calculation model; • even versus uneven clothing (insulation) distribution; •
VOR, the versatile optimal resolution chopper spectrometer, is designed to probe dynamic phenomena that are currently inaccessible for inelastic neutron scattering due to flux limitations. VOR is a short instrument by the standards of the European Spallation Source (ESS), 30.2m moderator to sample, and provides instantaneous access to a broad dynamic range, 1-120 meV within each ESS period. The sh
Much research has been published which attests to desire felt by educators to improve the quality of student reflection, and engagement with learning, through processes of assessment. This paper describes how research in Systems Analysis is being transformed and applied to educational practice. Staff considered that methods were needed to stimulate students to reflect and engage in higher orders o
In recent decades, a ‘Haitian Turn’ has emerged as both academic and public readerships in the anglophone sphere have been flooded by a wave of essays, articles, and monographs on the Haitian Revolution (1791–1804). At the epicentre of the present study is one of the major interpretations of the Haitian Revolution in the Haitian Turn, which I call the ‘universality paradigm’.

At the epicentre of the present study is one of the major interpretations of the Haitian Revolution in the Haitian Turn, which I call the ‘universality paradigm’. The universality para
Knowledge of DNA - lipid layer interactions is key for the development of biosensors, synthetic nanopores, scaffolds, and gene-delivery systems. These interactions are strongly affected by the ionic composition of the solvent. We have combined quartz crystal microbalance (QCM) and ellipsometry measurements to reveal how pH, buffers and alkali metal chloride salts affect the interaction of DNA with
The demand for kidney transplantation is growing while the number of donors continues to be insufficient, prolonging the process. Today’s method has a short time frame for carrying out the transplant, where the kidney must be taken out within 30-60 minutes after death. Due to lack of time and logistics, this often creates a major problem and inhibits transplantation. UGLK Science has developed a s
Background: Cure proportion represents the proportion of patients who experience the same mortality rate as the general population and can be estimated together with the survival of the proportion experiencing excess mortality (the uncured). The aim was to estimate the cure proportions and survival among uncured stage II–III cutaneous melanoma (CM) patients. Methods: 1‐ and 5‐year relative surviva
Background: Being an informal carer of a person with dementia (PwD) can have a negative effect on the carer’s health and quality of life, and spouse carers have been found to be especially vulnerable. Yet relatively little is known about the care provided and support received by spouse carers. This study compares spouse carers to other informal carers of PwDs regarding their care provision, the su
The sun is the most important energy source for the Earth’s climate system, however, influences of solar variations on climate are not fully understood. Studying past solar activity can improve our understanding of what role the sun plays in Earth’s climate. Cosmogenic radionuclides, such as 10Be in ice cores, are powerful tools to reconstruct past solar activity before the period of direct telesc
The synthesis and crystal structure of rhodamine 590 acid phthalate (RhAP) have been reported. This novel solid-state rhodamine derivative not only has a longer fluorescence lifetime compared to rhodamine solid-state matrixes where emission is quenched but also possesses strong nonlinear optical characteristics. The static and dynamic first- and second-order hyperpolarizabilities were calculated u
The non-enzymatic browning known as the Maillard reaction has been the subject of extensive investigation for decades. Studies have focused on areas such as changes in flavour, colour, texture, and the nutritional properties of food materials as a result of this reaction. However, this complex reaction between the amino acids in proteins and reducing sugars in carbohydrates, is still not fully und
We present new algorithms for simulating Bose–Einstein correlations among final-state bosons in an event generator. The algorithms are all based on introducing Bose–Einstein correlations as a shift of final-state momenta among identical bosons, and differ only in the way energy and momentum conservation is ensured. The benefits and shortcomings of this approach, that may be viewed as a local rewei
The kinetics of sorption of water vapor in mature cement mortar are examined experimentally by the use of a sorption balance (DVS1000). The relative humidity in the sample chamber is obtained by mixing dry and saturated air using flow regulators with very high accuracy. A predefined change of relative humidity in the sample chamber can be obtained in about 30 s. The time needed for equilibration i
This paper is about automatic classification of dialect and accent type in Swedish. We used disyllabic words from the speech material of the Swedia 2000 dialect project in order to build a statistical prediction model. The model uses different parameters extracted from F0 contours of the words. Classification of dialect is performed for the features 'province' and 'village', whereas classification
