Because of its large ratio between strength and weight timber is a material very suitable for large span structures. For large spans of more than about 30 m, usually truss structures are adopted. The problem of large span timber truss structures are the expansive and complex nodes that have to be adopted, normally single or multiple slotted-in steel plates in combination with a number of dowel
It is widely recognised that the two major challenges of the 21st century are climate change and poverty. The building sector is responsible for over a third of all global carbon dioxide emissions. At the same time, we see vastly overcrowded and rapidly growing informal settlements in developing countries, where people lack the basic right to decent shelter. This is simply not sustainable and forc
Den moderna tidens tekniska utveckling har lett till att allt större och mer omfattande skadeståndsmål anhängiggörs i domstolarna. Fler sakägare är berörda, de tvistiga frågorna i målet är allt mer tekniskt komplicerade och bevismaterialet är omfattande. Domstolarna har stundom hanterat en sådan situation genom att använda sig av pilotmålsmodellen. Modellen har ingen klar definition och användningTechnological development in modern times has led to increasingly larger and more extensive tort cases being brought before courts. The processes are difficult to handle, time-consuming and costly. The courts have occasionally handled the situation by using a model called “pilotmålsmodellen” (or “test case model”). The model has no clear definition and the field of usage is indistinct. The model i
During the 90’s intersex individuals was found among fish downstream sewage treatment plants, this was found to be due to estrogens in the water. Today we know that one of the largest contributors of the effects on fish is 17a-ethinylestradiol (EE2). EE2 is a synthetic estrogen used in contraceptive pills and is one of the most used pharmaceuticals in the world. In addition to intersex EE2 also ge
Dynamically predicted shelf-life label (DPSL) has been discussed to be one of the solutions to curb meat waste. Therefore, the research about the DPSL label and the perceptible information obtained by minced meat consumers is conducted. The research purpose is to identify the critical factors to design a DPSL label for minced meat consumers, and to design and assess the label with the consumers. T
This report studies how community stakeholders describe their ability to handle accidents and crises. The aim of the report has been to study what has been written on the subject scientifically and in Swedish legislation. There are primarily two areas where ability is described; the field of protection against accidents and the emergency management field. A major part of the report is a content an
The aim of the thesis is to evaluate the reaction in fiscal stance in EMU with the purpose to investigate if there is a need for discretionary fiscal policy as a stabilizing mechanism due to the existence of country-specific disparities in order to counteract business cycle fluctuations in the Monetary Union. The second objective is to analyse the role of discretionary fiscal policy during three d
H.G. Wells’ novella The Time Machine (1895) tells the story of The Time Traveller who travels to the year 802,701. There, he encounters two evolutionary progressions of humanity. One, Morlocks, have been read as representations of Victorian workers and poor, and the other, the Elois, as representations of the aristocracy. The Time Traveller represents the middle class. The novella is often seen as
Traditionally, diagnosis of male infertility has relied upon microscopic assessment of semen. The normality criteria set by the World Health Organization (WHO) in regard to sperm concentration, motility and morphology are, however, poor predictors of fertility. In about half of the involuntarily childless couples the causes are solely or partly male related. In 60-75% of cases the aetiology of red
Background: Risk factors for hip fracture are well studied because of the negative impact on patients and the community, with mortality in the first year being almost 30% in the elderly. Age, gender and fall risk-increasing drugs, identified by the National Board of Health and Welfare in Sweden, are well known risk factors for hip fracture, but how multimorbidity level affects the risk of hip frac
Molecularly imprinted polymers (MIPs) targeting quercetin were prepared from 4-vinylpyridine and ethylene dimethacrylate (EDMA) under various solvent systems with the aim to form MIPs with high recognition for the quercetin molecule in aqueous systems at high temperature. A MIP prepared from the three-component solvent mixture of THF/H2O/MeOH showed potential in its application for the determinati
Organic micropollutants comprise a diverse set of molecules, varying both with regard to the frequency of their use, as well as the potential harm they can inflict upon aquatic ecosystems. Ozonation has been recognized as an efficient method for their abatement, due to its ability to selectively oxidize molecular groups commonly found on organic molecules. Micropollutants are, however, rarely degr
The paper reviewed a collection of studies from 2015-2025 in Sweden on municipal organizational change, with the aim of discussing challenges and benefits during modern change processes and connecting it to previously existing theories. The results showed that there is some conflict between different governance models (mainly NPM and TBG), that TBG can be implemented differently in different munic
The commercialization of athletes has been an important aspect of the sports industry and personal branding in the contemporary landscape of digital media and sports communication. However, the commercialization of the athletes will be interpreted under the framework of national symbolism when the athletes are constructed as national symbols at the same time. Starting by researching the case of Ei
BACKGROUND: Pelvic obliquity (PO) is common in individuals with cerebral palsy (CP). The prevalence of PO in a population of children with CP and its associations with scoliosis, hip displacement and asymmetric range of hip abduction were analysed. METHODS: Over a 5-year period all pelvic radiographs from the Swedish surveillance programme for CP and the recorded data for scoliosis and hip abducti
BACKGROUND: Food choice decisions are complex processes influenced by various factors that affect the family's diet and, thus, their health and nutrition. In low- and middle-income countries like Ethiopia, these factors are shaped by the ongoing nutrition transition, urbanization, and socio-economic challenges. Despite growing concerns about the double burden of malnutrition, the factors influenci
Timely detection and surveillance of disease community spread is a potent tool for implementing effective public health interventions. This study investigates the National Telehealth Service (1177 helpline) across 18 regions in Sweden in 2020 to identify early signals of community transmission of COVID-19 at the beginning of the pandemic. Focusing on calls related to key COVID-19 symptoms (cough,
This study explores how scientists navigate research topic transitions during their early-career training and examines its impact on the production of novel knowledge. Drawing on survey data of 270 mid-career scientists in life sciences, we investigate their time investment in topics during early career stages (i.e. during PhD and postdoc training) and trace their research output for 15 years afte
