Aim. The aim of this study is to examine associations between caregiver burden, perceived health and sense of coherence in family caregivers to persons with dementia living at home. Background. Most of the studies on family caregivers have focused on burden and morbidity. However, the caregiver's sense of coherence and perceived health have not been studied earlier in relation to caregiver burden.
This chapter presents key energy use figures and explores the energy saving potential for electric lighting in office buildings based on a review of relevant literature, with special emphasis on a North European context. The review outlines that an energy intensity of around 10 kWh/m2yr is a realistic target for electric lighting in future low energy office buildings, based on theoretical calculat
This paper offers an analysis of a case of cooperation, and in particular cooperation problems, between independent performing arts organisations in the region of Skåne, Sweden. The cooperation in question flows from visions of the organisations, and linked regional commission to develop the infrastructure and networks of the independent performing arts in Skåne. The case gives evidence of the cha
Exoplanets have been observed at many stages of their host star's life, including the main-sequence (MS), subgiant and red giant branch stages. Also, polluted white dwarfs (WDs) likely represent dynamically active systems at late times. Here, we perform three-body simulations which include realistic post-MS stellar mass-loss and span the entire lifetime of exosystems with two massive planets, from
We apply causal loop diagrams (CLD) to picture how complex societal scenarios can be understood in terms of interdependent drivers and mechanisms between actors from the public and private sectors respectively. And we show how un-sustainable scenarios can be understood in terms of insufficient balancing feed-back in the system. We apply the methodology to picture such imbalances as funda- mental d
Popular Abstract in English This thesis considers a model of high energy particle collisions. The model is based on the so called BFKL formalism which is valid only at low x, that is collisions at very high energies, such as at the LHC. The intial state of the incoming particles are simulated by colour dipoles in transverse space evolved through rapidity. With this approach, all fluctuations are dThis thesis considers a model of high energy particle collisions. The model is based on the so called BFKL formalism which is valid only at low x, that is collisions at very high energies, such as at the LHC. The intial state of the incoming particles are simulated by colour dipoles in transverse space evolved through rapidity. With this approach, all fluctuations are dynamically described, allowi
For the development of single–ion irradiation system for living cells at the Lund Ion Beam Analysis facility (LIBAF) newly developed pre-cell (PC) detectors have been investigated. Central to the thesis is the fabrication and initial characterization of more than 100 ultra-thin silicon detectors having different thicknesses down to 5 μm with active areas ranging from 0.71 to 0.172 mm2, to be used
This book chapter discusses and evaluates four different efforts to extend human life: Normalize ageing, Optimize ageing, Retard ageing and postpone death, and Eliminate or overcome ageing and death. I suggest that improved treatment of disease and handicap at all ages should be welcomed. As a secondary effect, this may in many cases result in an extension of individual lives. However, the direct
A literature review and a questionnaire study with 62 participants were carried out to provide recommendations on the design of a set of evacuation systems for road tunnels: 1) Traffic Information Sign (TIS) - message and size of the sign (large or small), colour scheme, and use of pictograms and/or flashing lights, 2) Emergency exit portal layout - colour scheme, 3) Acoustic systems - voice messa
Historical demography, which is the study of human population dynamics in the past, is central for understanding human behaviours and traits, such as fertility, mortality and migration. An important factor in demographic research is the geographic context. Where people lived often determined their social ties, exposure to diseases and economic development. Such information is essential not only fo
This paper deals with the joint estimation of spatial mode shapes and temporal frequencies from transient vibrations measured by a uniform circular array of sensors encircling a cross-section of a cylinder. The geometry allows each 2D mode to be interpreted as two real planar waves impinging from mirrored directions with respect to the broadside of a uniform linear array. Algorithms for joint esti
Popular Abstract in Swedish Denna avhandling presenterar nya metoder för att analysera bilder på hjärtat för att utesluta eller bekräfta kranskärlssjukdom. Hjärtat har en livsviktig uppgift, att pumpa runt blodet för att förse alla kroppens organ med energi och syre. Vid förträngningar i kärlen som försörjer hjärtmuskeln med blod (kranskärlen) uppkommer ett tillstånd som kallas ischemisk hjärtsjukIn this thesis, methods for automated analysis of myocardial perfusion single photon emission computer tomography (myocardial perfusion SPECT, MPS) images have been successfully developed and evaluated. MPS images show the perfusion of the myocardium and are used for diagnosing patients with suspected ischemic heart disease. The disease is characterized by reduced perfusion to a region of the myoc
