Background: Dementia with Lewy Body (DLB) is a neurocognitive disorder with core features, such as Parkinsonism, visual hallucinations, and fluctuating cognition/ excessive daytime sleepiness, and supportive features, such as rapid eye movement sleep behaviour disorder. DLB is often misdiagnosed and unrecognized in elderly individuals. A diagnosis of DLB is important because of the risk of hyperse
The doctoral thesis seeks to discuss the transition between Viking Age and early medieval settlement and the establishment of the historical villages, based on archaeological material collected in Halland. The development is described in terms of three general periods of change: Period 1, c. 800–1000, consisting of farms with three-aisled longhouses. Period 2, c. 1000–1150, a transitional period w
The changing forms of governance stemming from the rise of New Public Management (NPM) and New Public Governance (NPG) have brought about significant changes in the relationship between the public and private sectors (Christensen and Lægreid 2007; Torfing and Triantafillou 2013). Not only have we witnessed a gradual increase in the involvement of private actors in the provision of public services,
Context. At about 1000 days after the launch of Gaia we present the first Gaia data release, Gaia DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magnitude 20.7. Aims. A summary of Gaia DR1 is presented along with illustrations of the scientific quality of the data, followed by a discussion of the limitations due to the preliminary nature of this release.

Background: A key innovation may allow one group of species to radiate and replace another, but the role of competition and background extinctions for the replacement process is vigorously debated and unclear. Questions: Is a minimum competitive advantage necessary to initiate replacement? Are background extinctions of the incumbent species necessary? What speciation and extinction dynamics charac
Popular Abstract in Swedish Ta ett djupt andetag och tänk på vad du nu har i lungorna! Jo, det är luft, förstås, syre kväve och sådant. Men det är också något annat. I varje kubikcentimeter du andas in finns tusentals partiklar, alla för små för att kunna ses med blotta ögat. Om dessa partiklar handlar denna avhandling. Vi kallar luftburna partiklar för aerosoler, ett begrepp som innefattar allt Airborne particles are everywhere around us, and have always been. Particles generated by human activities has increased drastically since industrialization, and several epidemiological studies have shown that inhaled particles can cause adverse health effects. The concern about health effects have during the last decade shifted towards fine and ultrafine particles, not least due to the emerging f
Popular Abstract in Swedish Vår värld drivs av förbränning. Från den lilla elden som används vid matlagning till gigantiska gasturbiner och kolkraftverk som genererar en stor del av all elektricitet. Dessutom så drivs nästan alla fordon av förbränningsmotorer. Det har uppskattats att över nittio procent av alla energi vi i världen omvandlar kommer från förbränning i någon form. Det är således ganHigh repetition rate laser diagnostics has proven to be a useful tool for studying combustion phenomena. Laser techniques are, in general, relatively non-intrusive and have the potential to measure specific species at very low concentrations and with extremely high temporal resolution. However, most laser systems in this field of research are limited to repetition rates below 100 Hz, and are thus
Context: Immune functions seem to have connections to variations in body fat mass. Studies of knockout mice indicate that endogenous interleukin (IL)-1 can suppress mature-onset obesity. Objective: To systematically investigate our hypotheses that single- nucleotide polymorphisms (SNPs) and/or haplotypes variants in the IL-1 gene system are associated with fat mass. Subjects: The Gothenburg osteop
The aim of this study was to investigate the short-term (2 weeks) effects of the herbicide metsulfuron methyl alone and in combination with the insecticide cypermethrin in freshwater enclosures (80 1). We used a factorial design with four levels of herbicide (0, 1, 5, 20 mug/1) and two levels of insecticide (0 and 0.05 mug/1). The root growth of the macrophyte species Elodea canadensis and Myrioph
De senaste årens fokus på säkerhetsrisker i samhället har gett upphov till olika former av polisarbete, såsom gränsöverskridande och underrättelsebaserat polisarbete. Den här studien uppmärksammar ett samverkansprojekt mellan gränsmyndigheter i Östersjöområdet som pågick mellan 2014 och 2015. Projektet fick namnet Turnstone och involverade underrättelsepoliser, gränspoliser och kustbevakare från SThe risks and insecurities emphasised in contemporary societies have given rise to diverse forms of policing, such as transnational and intelligence-based police collaborations. This dissertation focuses on a border police collaboration project, called Turnstone, that took place between 2014 and 2015, aiming to address issues related to irregular migration and cross border crimes in the Baltic Sea
Background: Recent data imply young patients (age ≤50 years) undergoing small-bowel (SB) capsule endoscopy (CE) for iron deficiency anaemia (IDA) show higher diagnostic yield (DY) for sinister pathology. We aimed to investigate DY of CE in a large cohort of young IDA patients, and evaluate factors predicting significant SB pathology. Materials and methods: This was a retrospective, multicentre stu
AbstractObjectives: Patients with inflammatory rheumatic diseases (IRDs) have higher risk of serious infections than healthy individuals due to their illness, comorbidities and treatments. Streptococcus pneumoniae is responsible for 30-50% of community aquired pneumonia in Europe.The proportion of patients with IRD receiving vaccination against pneumococci is still estimated to be suboptimal. The
A Free Electron Laser (FEL), is a device that generates extremely coherent and brilliant radiation using electrons accelerated to relativistic velocities in a particle accelerator. The process utilises similar equipment to what is used at a synchrotron source like MAX IV, but in addition there is an interaction between the relativistic electron beam and the generated radiation to achieve an expone
User interfaces to control machines are a critical part of any technology that requires user inputs. The user interface works as a link between human and machine, and it is vital that this link is understandable for both parts. Therefore, the design of the interface is of great importance in order to fully utilize the capabilities the technology provides. Assa Abloy is a company that offers soluti
Metodutveckling för analys av cellulärt upptag av nanopartiklar Cancer är idag en utbredd sjukdom som tusentals människor världen över diagnostiseras för dagligen. Möjligheterna att få en korrekt behandling ökar om tumörer upptäcks i ett tidigt skede tidigt vilket ger en större chans att tillfriskna. Men detta har visat sig vara en utmaning då nuvarande metoder som används inte är av tillräckligAbstract MRI, magnetic resonance imaging, is used for disease detection such as assessing blood flow, detecting tumours and diagnosing many forms of cancer. Contrast agents are chemical substances that increase the MRI sensitivity. One class of contrast agents are the so called nanoparticulate contrast agents. Since tumour-associated formation of new blood vessels often results in highly permeab
Sweden has a vision of building a sustainable society. To reach this vision a number of goals, such as transportation political goals, regional goals and environmental goals, have been set. One way to reach the aforementioned transportation political goals for a good and safe traffic environment is to increase the use of public transport and thereby reduce the need for people to use their car. Com
The MS thesis is concerned with the problem of scheduling the daily energy loads in a multihouse environment from the point of view of an energy retailer. We assume that the residential users own a set of home appliances (washing machines, dishwashers, ovens, microwave ovens, vacuum cleaners, boilers, fridges, water purifiers, irons, TVs, personal computers and lights) that are supposed to be use
In May 2009, a new Swedish legislation made it possible for a new tenure to enter the housing market – condominiums. Since the law took effect, only a few condominiums have been built, mainly by minor construction- and property companies. This thesis aims to investigate under what circums- tances it’s favorably to build condominiums and also to identify what ob- stacles and opportunities that c
Popular Abstract in Swedish Bakgrund Man kan fråga sig varför en hel avhandling handlar om något så ovanligt som akut mastoiditit hos barn. Det är den vanligaste komplikationen till öroninflammation men drabbar bara 20-60 barn per år i Sverige. Öroninflammation däremot är en infektion som är så vanlig att nästan alla har haft åtminstone en sådan som barn. I Sverige diagnostiseras upp emot 200 000 One of the greatest threats to society today is the development of bacterial resistance to antibiotics. It is commonly accepted that this is mainly due to the use of antibiotics. Acute otitis media (AOM) is responsible for the highest number of antibiotic prescriptions to children although it is in most cases a self-limiting disease. Nevertheless, complications do occur in some case and the most c
