Popular Abstract in Swedish Partiella differentialekvationerna} är kraftfulla verktyg som kan användas för att beskriva fysikaliska fenomen inom bland annat naturvetenskap, teknik, ekonomi och medicin. Listan med tillämpningar kan göras hur lång som helst: Partiella differentialekvationer kan beskriva hur en snöflinga bildas, hur strukturer deformeras när de utsätts för mekaniska krafter, hur blodSplitting methods are widely used as temporal discretizations of evolution equations. Such methods usually constitute competitive choices whenever a vector field can be split into a sum of two or more parts that each generates a flow easier to compute or approximate than the flow of the sum. In the research presented in this Licentiate thesis we consider dissipative evolution equations with vector

The widespread use of artificial nestboxes has led to significant advances in our knowledge of the ecology, behaviour and physiology of cavity nesting birds, especially small passerines Nestboxes have made it easier to perform routine monitoring and experimental manipulation of eggs or nestlings, and also repeatedly to capture, identify and manipulate the parents However, when comparing results ac

Brain-machine interfaces (BMIs) based on extracellular recordings with microelectrodes provide means of observing the activities of neurons that orchestrate fundamental brain function, and are therefore powerful tools for exploring the function of the brain. Due to physical restrictions and risks for post-surgical complications, wired BMIs are not suitable for long-term studies in freely behaving

The aim of this dissertation is to present a history of sex education films in Sweden, from their beginnings until the late 1970s, relating the films to the changing historical context of the Swedish welfare society. Within this framework, the dissertation explores two main sets of questions. First, utilizing a contextual understanding of genre, the dissertation analyzes how the films were produce

This thesis covers areas within estimation and optimal control of vehicles, in particular four-wheeled vehicles. One topic is how to handle delayed and out-of-sequence measurements (OOSMs) in tracking systems. The motivation for this is that with technological development and exploitation of more sensors in tracking systems, OOSMs gain more significance in various applications. The thesis derives

The Baltic Sea is one of the largest seas with brackish water and is sensitive ocean partly due to its long retention time and partly due to its high human load or the combination between the two. In Scania there are 33 municipalities where 16 of these are located along the coast. However, due to that the knowledge about coastal management varies between the municipalities Integrated Coastal Zone

Sammanfattning Våldtäkt har sedan länge varit kriminaliserat, men dess innebörd och syftet bakom kriminaliseringen har varierat. Under 1800-talets slut var det främsta syftet att upprätthålla familjens, i synnerhet mannens, ära. Inte förrän 1965 blev våldtäkt inom äktenskap kriminaliserat, då kvinnans sexuella integritet ställdes i fokus. Därefter förstärktes den sexuella integriteten ytterligareSummary Rape has been criminalized for a long time, but the meaning and intention has been shifted. During the end of 1900th century the primary intention was to enforce the honour of the family, particularly that of the man. Not until 1965 rape became criminalized within marriage, as the sexual integrity of women came into focus. Subsequently the sexual integrity was enhanced by expanding 6 chap

To produce food that ends up being thrown away is a big unnecessary climate impact which is easily avoided by just treating the product in a different way. There are many reasons why food waste appears, it could be that the “best before” date has expired, the product has been damaged or it is something wrong with it from the beginning. The biggest reason for food waste is that the “best before” da

Background: The aim was to develop a theoretical framework for how errors in estimated activities propagate to a dispersion in time-integrated activity in radionuclide-therapy dosimetry and how this affects the comparison of radionuclide-therapy dosimetry schemes. Methods: Formulae for the variance of relative errors of estimated time-integrated activities and relative differences in time-integrat

Upon hearing the phrase Some cats meow, a listener might pragmatically infer that 'Some but not all cats meow'. This is known as a scalar implicature and it often arises when a speaker produces a weak linguistic expression instead of a stronger one. Several L2 studies claim that pragmatic inferences are generated by default and their comprehension presents no challenges to L2 learners. However, th

Studies on cortical function have been a cornerstone in research trying to understand our brains for a long time. For many years now a basic feature of cortical processing has been the idea of a functional localization, with different areas or even neurons in the cortex having clear, individual, functions. This idea has been challenged from the outset, and with new methods to study the cortex the

Background: We investigated the impact of time to adjuvant chemotherapy (AC) on survival after surgical resection (<8 weeks or 8–16 weeks) for patients with non-small cell lung cancer (NSCLC) by applying a target-trial emulation. Material and Methods: We used Swedish population-based healthcare registries to emulate a hypothetical target trial, with treatment arms of ‘initiate AC <8 weeks postoper

This presentation reports on a study of the writing behaviour of some (n=21) Swedish speaking 14-15-year olds when composing in Swedish, their first language, and in English as a foreign language. The approach taken in this study is a psycholinguistic/cognitive one using the key-stroke logging tool, ScriptLog (Strömqvist & Karlsson, 2002; Strömqvist & Malmsten, 1998, see www.scriptlog.net

Optical genome mapping in nanochannels is a powerful genetic analysis method, complementary to deoxyribonucleic acid (DNA) sequencing. The method is based on detecting a pattern of fluorescent labels attached along individual DNA molecules. When such molecules are extended in nanochannels, the labels create a fluorescent genetic barcode that is used for mapping the DNA molecule to its genomic locu

The overall tumour incidence and breast cancer incidence related to hormone replacement therapy (HRT) were followed in a population-based cohort of 29 508 women, aged 25-65 when interviewed in 1990-92. By the end of the follow up in December 1999, there were 226 611 person-years of observation. A total of 1145 malignant tumours were recorded (expected 1166.6; SIR = 0.98, 95% CI 0.93-1.04). There w

Joint diseases are often characterized by inflammatory processes that result in pathological changes in joint tissues, including cartilage degradation and release of components into the synovial fluid. The complement system plays a central role in promoting the inflammation. Because several cartilage proteins are known to interact with complement, causing either activation or inhibition of the sys

OBJECTIVE: The objective of this nationwide study was to analyze how functional status and socioeconomic status affect return to work (RTW) among younger patients with first-time stroke in a Sweden.MATERIAL AND METHODS: This register-based cohort study included employed patients aged 25-55 with first-time stroke between 2008 and 2011 and primary outcome was RTW within 1 year after stroke. Data reg

Although deaf children depend upon sight for communication, retinitis pigmentosa is present in 6 per cent of those with a profound hearing deficit. Usher syndrome type 1 (USH-1) is an autosomal recessive disease characterised by profound hearing impairment, absent vestibular function, and progressive loss of vision due to retinitis pigmentosa. Owing to the severe handicap of the combined disorders

Background: Optimal adjunctive therapy in ST-segment elevation myocardial infarction (STEMI) patients treated with primary PCI (PPCI) remains a matter of debate. Our aim was to compare the efficacy and safety of bivalirudin to unfractionated heparin (UFH), with or without glycoprotein IIb/IIIa inhibitors (GPI) in a large real-world population, using data from the Swedish national registry, SWEDEHE
