X-ray phase-contrast imaging has recently led to a revolution in resolving power and tissue contrast in biomedical imaging, microscopy and materials science. The necessary high spatial coherence is currently provided by either large-scale synchrotron facilities with limited beamtime access or by microfocus X-ray tubes with rather limited flux. X-rays radiated by relativistic electrons driven by we
District heating (DH) systems may contribute to reducing the use of fossil fuels for heating purposes since they enable the use of waste heat and facilitate the use of renewable energy sources. This paper focuses on the transformation of the Swedish DH systems with regard to energy supply in 1960–2011. Swedish DH production was completely dependent on oil until the late 1970s, while today it is do
Vertebrates possess different types of retinal specializations that vary in number, size, shape, and position in the retina. This diversity in retinal configuration has been revealed through topographic maps, which show variations in neuron density across the retina. Although topographic maps of about 300 vertebrates are available, there is no method for characterizing retinal traits quantitativel
Since 2006, the Pacific oyster Crassostrea gigas has been a permanent resident on the west cost of Sweden. Because C. gigas is nonindigenous in Scandinavia, it may modify ecosystems and affect the resident biota. Individuals of C. gigas often settle in large aggregations, and the physical structure of the resulting reef provides attachment points and refuges for many secondary species. However, C.
To investigate the associations between cytokines and insulin sensitivity in Swedish residents born in Iraq and Swedish residents born in Sweden.
Education is usually seen as an instrument for making changes in knowledge, values and norms. Norms are action instructions or imperatives and thus direct actions and changes, which is the essence of norms. If one knows more about norms – guiding actions – one understands more about changes. It is well-known in sociology of law that there is an important, complex interplay between social norms and
Context-aware computing is a typical paradigm of ubiquitous computing and aims to provide context information anywhere and anytime. Context data management which handles gathering, processing, managing, evaluating and disseminating context information is the heart of context-aware system. Context provision and acquisition, thus, become crucial for context-aware computing. In order to decouple appl
Background. Currently there is no consensus on the use of adjuvant radiotherapy (RT) in retroperitoneal sarcoma (RPS). We have analysed clinical outcomes in patients with localised RPS treated at two Scandinavian Sarcoma Group (SSG) centres: Haukeland University Hospital (HUH), Bergen, Norway and Skane University Hospital (SUH), Lund, Sweden to clarify the effects of adjuvant RT on local control a
Popular Abstract in Swedish Vår kropp består av olika celler som kommunicerar med varandra genom signalering. Cellerna tar emot signaler från omgivningen med hjälp av proteiner som sätter sig fast på deras yta genom mottagare, så kallade receptorer. När receptorerna får signaler skickas de vidare in i cellkärnan där det bestäms hur cellen ska agera. Tyrosinkinasreceptorer är proteiner som sitter pFLT3, a receptor tyrosine kinase, is expressed in hematopoietic progenitor cells. FLT3-ITD (internal tandem duplication) and D835 mutations are found in approximately 30% and 7% of Acute Myeloid Leukemia (AML) patients respectively, and correlate with a poor prognosis, thus making the mutated receptor a potential therapeutic target. FLT3 mutations cause constitutive activation of intrinsic tyrosin
Abstract The overall aim of this thesis was to increase knowledge about underlying causes and perioperative risk factors of Acute Confusional State (ACS) in elderly patients with hip fracture and to investigate the effect of a multi-factorial intervention program in order to decrease the number of patients who develop ACS. The aim in paper I was to describe elderly patients with hip fracture on th
Recent research shows that a nocturnal hawkmoth, Manduca sexta, inspects flowers in search for nectar by means of a series of hovering and proboscis movements controlled by different sensory modalities, mainly vision and mechanoreception. The diurnal Macroglossum stellatarum is a closely related hawkmoth challenged with the same task but under illuminances 6-8 orders of magnitude higher. Here, we
Rättssociologiska enheten har haft uppdraget att utvärdera försöksverksamheten med barnahus för barn som utsatts för brott. Socialtjänst, sjukvård och rättsvårdande myndigheter ska samverka under ett tak, med målsättningen att barnanpassa utredningar och undvika att barn i onödan utsätts för upprepade kontakter med olika myndigheter. Utredningarnas kvalitet ska höjas för att ge bättre underlag för
Background: Certain immune-mediated diseases (IMDs) have been associated with increased risk for cardiovascular disorders. The aim of the present study was to examine whether there is an association between 32 different IMDs and first hospitalization for ischemic or hemorrhagic stroke. Methods: All individuals in Sweden hospitalized with a main diagnosis of IMD (without previous or coexisting stro
'SHUT UP ’N’ PLAY! Negotiating the Musical Work’ is a piece of artistic research that attempts to merge artistic practice, qualitative research methods and critical analysis in a project concerned with contemporary performance practices, and specifically how these practices are created and transmitted in the interaction between composer and performer. By way of a critical reading of the musico-phi
Researchers and society devote increasing interest to environmental impact assessments. The study here discusses and questions current assessment models by relating them to inter-organizational network analyses, and demonstrates that single entities as the basis for environmental impact assessments may not be in the best interests of society. Three case studies focusing on logistical solutions ill
