SPECT Imaging using Pinhole Collimation : System Design and Simulation Studies for Pre-Clinical and Clinical Imaging
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
Reclaiming Territory from Below : Grassroots Environmentalism and Waste Conflicts in Campania, Italy
In the course of 2000s, the region of Campania in southern Italy and its capital city Naples became global icons of waste mismanagement after the images of piles of rubbish occluding their urban areas hit the headlines. Conventional explanations, in Italy and elsewhere, pointed to administrative failure, cultural backwardness and mafia infiltration as the main causes of waste mishandling. In the s
Effects of forest management on greenhouse gas fluxes in a boreal forest
Skogar täcker ca 31% av jordens landyta och lagrar stora mängder kol i biomassa och i marken. I klimatavtalet från Paris 2015 lyfts skogars roll som sänkor och reservoarer av kol fram och undertecknande länder uppmanas att implementera strategier för hållbart skogsbruk som ytterligare förstärker skogars roll som sänkor av växthusgaser. Ett aktivt skogsbruk påverkar klimat och miljö på många olika Forest ecosystems cover 31% of the terrestrial land area and store large amounts of carbon in biomass and in soils. The 2015 Paris Agreement recognizes the importance of sinks and reservoirs of greenhouse gases (GHGs) in forests and the importance of enhancing them through sustainable forest management policies. Managing forests for climate mitigation purposes is, however, complex since management
Reduced Neuromuscular Performance in Amenorrheic Elite Endurance Athletes
INTRODUCTION: Secondary functional hypothalamic amenorrhea (SFHA) is common among female athletes, especially in weight-sensitive sports. The aim of this study was to investigate the link between SFHA and neuromuscular performance in elite endurance athletes. METHODS: Sixteen eumenorrheic (EUM) and 14 SFHA athletes from national teams and competitive clubs participated. Methods included gynecologi

Clinical characteristics of asymptomatic left ventricular diastolic dysfunction and its association with self-rated health and N-terminal B-type natriuretic peptide : a cross-sectional study
AIMS: Left ventricular hypertrophy, obesity, hypertension, and N-terminal B-type natriuretic peptide (Nt-proBNP) predict left ventricular diastolic dysfunction with preserved systolic function (DD-PSF). Self-rated health (SRH) is shown to be associated with chronic diseases, but the association of SRH with DD-PSF is unclear. In light of the clinical implications of DD-PSF, the following goals are
How predictions of economic behavior are affected by the socio-economic status of the target person
We investigate how the stereotype of the poor (vs. middle class) influences behavioral predictions. In Study 1 participants made predictions regarding another person’s economic behavior in scenarios pertaining to rate of time preferences (loss, gain of smaller and larger amount). We find that participants, across scenarios, expect individuals with low SES to show more short-sightedness, i.e., steeWe investigate how the stereotype of the poor (vs. middle class) influences behavioral predictions.
