Nuklearmedicinsk bildtagning med hjälp av radiofarmaka är ett viktigt verktyg för att studera biologiska processer och humansjukdomar. Bildtagning sker ofta med en detektor i kombination med en kollimator. En typ av kollimering är pinnhålskollimering, där ett pinnhål i ett opakt material placeras mellan en källa och en detektor. Pinnhålet fyller samma funktion som en optisk lins då emitterade fotoThe focus of this dissertation is the use of pinhole collimation in Nuclear Medicine. A pinhole is a single aperture in an opaque material that is placed between the detector and source of interest, and photons must pass through the hole to reach the detector. The choices of pinhole parameters, e.g. the pinhole material and size of the opening, are closely linked to the performance of the detector

The synthesis and characterization of three ligands and their respective heterobinuclear FeIIIZnII complexes were carried out, with the goal of mimicking the active site of purple acid phosphatases (PAPs). The ligand 2-hydroxy-3-(((2-hydroxy-5-methyl-3-(((2-(pyridin-2-yl)ethyl)(pyridin-2-ylmethyl)amino)methyl)benzyl)(pyridin-2ylmethyl)amino)methyl)-5-methylbenzaldehyde (H2L2) was synthesized and i

We study spectral properties of the Neumann–Poincaré operator on planar domains with corners with particular emphasis on existence of continuous spectrum and pure point spectrum. We show that the rate of resonance at continuous spectrum is different from that at eigenvalues, and then derive a method to distinguish continuous spectrum from eigenvalues. We perform computational experiments using the

Popular Abstract in Swedish Färger innehåller mer tillförlitlig information än vad bara skillnader i ljusintensitet gör. Det är därför inte svårt att förstå varför de allra flesta landlevande ryggradsdjur har färgseende. Några upplever en färgfattigare värld än vi människor, men många ser fler färgnyanser. På kvällen däremot gör bristen på ljus det svårt att se färger. Trots detta finns det nattakMost terrestrial vertebrates have colour vision, some perceive a less colourful world and others actually discriminate a wider colour spectrum than humans do. Still, we can all make use of the valuable colour information, which is more rigid than just brightness. However, at night when the light is dim, the lack of photons makes colour vision difficult. Nevertheless, some hawkmoths and bees can se

Det är nedslående att Cecilia Malmström givit upp kampen när det gäller fri- och rättigheter på nätet, skriver politiker och nätdebattörer. Den rättssäkerhet vi efterfrågar är en sådan som skyddar yttrandefriheten.

This paper investigates the association between perinatal health and all-cause mortality for specific age intervals, assessing the contribution of maternal socioeconomic characteristics and the presence of maternal-level confounding. Our study is based on a cohort of 12,564 singletons born between 1915 and 1929 at the Uppsala University Hospital. We fitted Cox regression models to estimate age-var

The EC-Earth earth system model has been recently developed to include the dynamics of vegetation. In its original formulation, vegetation variability is simply operated by the Leaf Area Index (LAI), which affects climate basically by changing the vegetation physiological resistance to evapotranspiration. This coupling has been found to have only a weak effect on the surface climate modeled by EC-

Let C be the unit circle in R2. We can view C as a plane graph whose vertices are all the points on C, and the distance between any two points on C is the length of the smaller arc between them. We consider a graph augmentation problem on C, where we want to place k⩾1 shortcuts on C such that the diameter of the resulting graph is minimized. We analyze for each k with 1⩽k⩽7 what the optimal set of

The physical proximate composition and physicochemical characteristics, microbiological stability, and in vitro alpha-amylolysis rate of flours produced by conventional dehydration techniques of the edible portions of the aroids Xanthosoma sagittifolium and Colocasia esculenta were investigated. Flours from the edible portion of both tubers did not show significant statistical differences in moist

We review recent results on chiral SU(2)L ×SU(2)R ≈ O(4) and U(1)A symmetry restoration in QCD. In particular, we discuss how Ward Identities allow one to derive general results on partner degeneration, which shed light on the distinction between the O(4) and O(4) ×U(1)A patterns of the chiral transition. For that purpose, susceptibilities associated with the O(4) and U(1)A symmetries are studied.

A broad range of rare inherited metabolic disorders can present with dystonia. For clinicians, it is important to recognize dystonic features, but it can be complicated by the mixed and complex clinical picture seen in many neurometabolic patients. Careful phenotyping is the first step towards the diagnosis of the underlying condition and subsequent targeted treatment, further supported by imaging

Objective: The introduction of hematopoietic stem cell transplantation (HSCT) has significantly improved the life-span of Hurler patients (mucopolysaccharidosis type I-H, MPS I-H). Yet, the musculoskeletal manifestations seem largely unresponsive to HSCT. In order to facilitate evidence based management, the aim of the current study was to give a systematic overview of the orthopaedic complication

Chronic liver disease (CLD) is frequently seen in the hemophilia population. The ADVANCE Working Group conducted a cross-sectional study in which people with hemophilia (PWH) aged ≥40 years were included. This study aimed to assess the associations between CLD and its risk factors using data from the H3 study, and to suggest implications for optimal care.Data from 13 European countries were collec

In many parts of the world, agricultural ecosystems are increasingly exposed to severe drought, and rainfall events due to climate changes. This coincides with a higher vulnerability of crops to soil-borne diseases, which is mostly ascribed to decreased resistance to pathogen attacks. However, loss of the natural capacity of soil microbes to suppress soil-borne plant pathogens may also contribute
