Activity determination from scintillation camera images using the conjugate view method may be inaccurate because of variation in scattered radiation from adjacent organs and activity from overlapping tissues. The aim of this study was to simulate patient scintillation camera images and from these evaluate the accuracy of 2 correction methods. The contribution from overlapping tissue activity was

This thesis is based on a close reading of Lawrence's novel The Trespasser from a Nietzschean point of view. By adopting this perspective it aims at giving the novel the sense of unity it has so far been alleged to lack. The analysis is preceded by a detailed discussion of the concept of literary influence. Since the purpose of this study is to illuminate what is unique in Lawrence's novel rather

An experiment was designed to resolve two largely unaddressed questions about the turnover of N in soils. One is the influence of microbial growth rate on mobilization and remineralization of cellular N. The other is to what extent heterotrophic immobilization of NO3- is controlled by the soil concentration of NH4+. Bacteria were extracted from a deciduous forest soil and inoculated into an aqueou

The visual system of nocturnal Hedyloidea butterflies was investigated for the first time, using light and electron microscopy. This study was undertaken to determine whether hedylids possess the classic superposition eye design characteristic of most moths, or apposition eyes of true butterflies (Papilionoidea), and, to gain insights into the sensory ecology of the Hedyloidea. We show that Macros

The aim was to investigate the influence of age and gender on quality of life (QoL), complaints, and the presence and nature of self-reported diseases in persons aged 75 and older with cancer (n = 150), compared to a matched group without cancer (n = 138). A second aim was to investigate factors associated with poor QoL in people aged 75 and older. QoL was measured with Short Form (SF-12) and Euro

Purpose: The expression and regulation of the different isoforms of nitric oxide synthase (NOS) in bladder smooth muscle cells are controversial and to our knowledge have not yet been studied systematically. Therefore, the expression and regulation of NOS were studied in rat bladder smooth muscle cells after stimulation with cytokines, lipopolysaccharide and L-arginine. Materials and Methods: Prim

The study aims at investigating the use of Landsat thematic mapper (TM) for mapping leaf area index (LAI) in coniferous and deciduous forests in southern Sweden. LAI has been estimated in the field with optical measurements, allometric equations, and litter-trap data, and empirical relationships between LAI estimates and satellite-measured reflectances have been analysed. Several common vegetation

We provide evidence that centromere-specific 155 bp DNA repeats terminate one pair of telomeres at the telocentric, left end of the short fourth chromosome in Chironomus pallidivittatus. Earlier evidence indicated that all other telomeres are terminated by 340 bp telomere-specific repeats. DNA that borders the 155 bp repeat contains a transcriptionally active 396 codon open reading frame (ORF) a f

Limitations of the pulse-shape discrimination (PSD) technique - a promising method to identify the charged particles stopped in planar Si-detectors - have been investigated. The particle resolution turned out to be basically determined by resistivity fluctuations in the bulk silicon which cause the charge-collection time to depend on the point of impact. Detector maps showing these fluctuations ha

Evidence is presented here from the northern Scandinavian Caledonides for development of an extensional basin of Ashgill to Mid Llandovery age along the Baltoscandian margin immediately prior to Baltica-Laurentia collision. U/Pb multigrain and ion microprobe zircon dating of plagiogranites in the Halti Igneous Complex complement previous baddeleyite and zircon dating of a dolerite dyke, and zircon

Objective: To describe physical activity of participants in the European Prospective Investigation into Cancer and Nutrition (EPIC). Design: A cross-sectional analysis of baseline data of a European prospective cohort study. Subjects: This analysis was restricted to participants in the age group 50-64 years, which was represented in all EPIC centres. It involved 236 386 participants from 25 centre

Popular Abstract in Swedish Avhandlingens titel Patterns of Care: Relating Altruism in Sociobiology and the Christian Tradition of Agape kan översättas som Omsorgsmönster: Förhållandet mellan hur altruism förstås i sociobiologin och den kristna agape-traditionen. (Ordet agape är grekiska för kärlek. Sociobiologi är ett naturvetenskapligt forskningsprogram som undersöker socialt beteendes biologisThe purpose of this study is to relate sociobiological theories of altruism to theories within the Christian tradition of agape. Firstly, it discusses the relation between scientific, ethical and theological understandings of altruism, and argues that it is possible to compare discussions of benevolent acts towards others or other-directedness. Such acts are determined in content by the extent an

Late medieval wall-paintings are part of sacred rhetoric, intended to convey the moral sense of Christian salvation history to churchgoers. The paintings of Albertus Pictor are studied according to the rhetorical principles set down in Augustine's De doctrina christiana and medieval scriptural interpretation.
