High diagnostic efficiency as well as the optimization of patient and staff doses in positron emission tomography (PET) can be achieved by implementing quality assurance program. This study was focused on the requirements and basic aspects of quality assurance (QA) in PET combined with computed tomography (CT), that include equipment quality control (QC). QA systems include methods of image QC, ex
EPR spectroscopy has been employed to determine the nature of vanadium (+4) species in the TiO2(B)-supported vanadia catalysts. IR and EPR studies show that multiple vanadia species are observed as a function of loading. At coverages greater than 3.5 theoretical layers, the EPR signal is reminiscent of bulk V205. At lower coverages, a different magnetic species dominates the resonance and may be a
Abstract in Uncoded languages Namen prispevka:Namen prispevka je analizirati ponovno podane izkušnje 27-ih preživelih vojne v Bosni in Hercegovini v 90-ih letih prejšnjega stoletja. V pripovedih smo pregledali verbalne znake sprave in pomiritve ter analizirali opisane izraze za spravo. Metode: Gradivo za raziskavo je bilo zbrano s kvalitativnimi intervjuji 27-ih posameznikov, ki so preživeli vojnoPurpose: The aim of this article was to analyze the retold experiences of 27 survivors from the 1990s war in Bosnia and Herzegovina. I have examined verbal markers of reconciliation and implacability and analyzed the described terms for reconciliation that are being actualized in the narratives. Design: The material for the study was gathered through qualitative interviews with 27 individuals who
Measurements have been performed at eight laboratories on Raman-shifted radiation from frequency-quadrupled Nd:YAG and KrF lasers. Each of these sources is a possible candidate for making differential-absorption lidar measurements of ozone in the free troposphere. The spectral purity, efficiency and divergence of the different sources are compared and explained using a simplified model of the Rama
PD (Parkinson's disease) is characterized by some typical motor features that are caused by striatal dopamine depletion and respond well to dopamine-replacement therapy with L-dopa. Unfortunately, the majority of PD patients treated with L-dopa develop abnormal involuntary movements (dyskinesias) within a few years. The mechanisms underlying the development of LIDs (L-dopa-induced dyskinesias) inv
Evolutionary theory predicts the existence of relatively stable sex differences in partner preferences with, for example, males being more concerned with traits predicting high fertility and females with traits predicting high resource availability. We tested three predictions using personal advertisements from both traditional newspapers and internet dating services. In accordance with prediction
At a time when natural petroleum resources are on the verge of depletion, and concern about climate change is increasing, the potential of lignocellulosic material for the production of bioethanol is well recognized. Ethanol can be produced from biomass through enzymatic hydrolysis and fermentation. However, to achieve high yields and high ethanol concentration, pretreatment of the cellulosic biom
The Danish religious landscape has been significantly transformed, especially during the last three decades. This transformation is marked by the shift from near religious hegemony towards a much more diverse religious population. Originally, the Danish Lutheran state church was closely intertwined with the governmental administration of the country after the reformation in Denmark of 1536 and the
The minimization of a functional consisting of a combined L 1/L 2-data-fidelity term and a total variation term, named L 1-L 2-TV model, is considered to remove a mixture of Gaussian and impulse noise in images, which are possibly additionally deformed by some convolution operator. We investigate analytically the stability of this model with respect to its parameters and link it to a constrained m
This paper assesses water quality that is used for vegetable irrigation in Tamale Metropolis, Ghana. A mixed-method of research design was employed in this study to collect and analyze the data based on survey instruments. The paper found that Escherichia coli (E. coli) that is usually used as an indicator of water contamination and heavy metals exist in all taken water samples. The mean concentra
This paper is a discussion on the relevance of compassion regarding human rights in liberal states. The study focuses a great deal on detangling and distinguishing compassion from other related terms and meanings that are commonly used as equivalent, somewhat differing and sometimes separate from each other. For this, Martha Nussbaum's account on compassion is used as a starting-point. Compass
Titel- Sex and the city för män? ?En kvalitativ studie om manligheter i förändring Författare- Malvina Britts Avdelning- Avdelningen för Medie- och kommunikationsvetenskap Problem: Området som min studie rör sig inom är representationen av maskulinitet. Förändringar i representationen av maskulinitet diskuteras i olika sammanhang och en specifik drama/komediserie, Entourage, har på sistone utmä
Abstract This thesis examines whether it is possible to ascertain a measurable difference between granted and refused grant applications with automatic methods. A corpus of project descriptions from the Swedish Science Council was examined with different classification techniques and using different linguistic features. A Naive Bayes classifier is shown to be a good predictor for this type of pro
The aim of this thesis is to investigate why the municipality of Lund has not done more, in relation to LundaMaTs, to inform and promote the purchasing of organic provisions to the public. This is of interest since it is determined in the Rio Declaration and Agenda 21 that the current unsustainable production and consumption patterns need to change. The local authorities play an important role
The frequent replacement of office furniture contributes to the increasing production of solid waste that leads to the use of more landfill space. Germany only produces approximately 700000 t of office furniture waste per year whereas most of this waste goes to landfill or incin-eration (Nolte, 2001). In addition, there are concerns about the use of hazardous chemicals in office furniture producti
Presentation of problem: The movement of sediment parallel to the coast by waves and currents is known as longshore sediment transport or littoral transport. Throughout the years, researchers have found that knowledge of longshore sediment transport is important in connection with coastal engineering design, such as construction of breakwaters at harbour entrances, dredging of navigation channels,
The present study investigated the effects of three factors on the level of realism in frequency judgements. These factors were: Instruction (No correction for guessing/Correction for guessing), Format (whether the frequency judgements were made in terms of absolute numbers or in percent) and Difficulty level (easy/hard set of questions). All three factors were found to have a significant effect o
Palliative care clinicians provide psychological support throughout their patients' journeys with illness. Throughout our series exploring the psychological elements of palliative care (PEPC), we suggested that the quality of care is enhanced when clinicians have a deeper understanding of patients' psychological experience of serious illness. Palliative care clinicians are uniquely poised to offer
