BACKGROUND: The diagnostic utility of magnetic resonance imaging in dementia workups has increased recently. The basic use is to exclude space-occupying processes in the brain. However, magnetic resonance imaging offers major opportunities for studying atrophy of specific brain areas. A great interest has been put in whether atrophy in the medial temporal lobe can serve as an early diagnostic mark
Using a generic electromagnetic model based on the spherical vector harmonics, we provide the Cramer-Rao lower bound (CRB) for direction-on-arrival (DOA) and polarization estimation with arbitrary multiport antennas. By reciprocity, the receiving multiport antenna is characterized in terms of the transmission matrix from incident voltage waves to multipole coefficients of the outgoing spherical ve
Sexual dimorphism is widespread in lizards, with the most consistently dimorphic traits being head size (males have larger heads) and trunk length (the distance between the front and hind legs is greater in females). These dimorphisms have generally been interpreted as follows: (1) large heads in males evolve through male-male rivalry (sexual selection); and (2) larger interlimb lengths in females
I inledningsföredraget vid KZG-konferensen ”Europabilder der Kirchen in der Nachkriegszeit” i Höör i augusti 1998 definieras först ”motstånd” som olika i Tyskland, i de ockuperade länderna, i Storbritannien och i ”neutrala” länder, resp. från biskopsstolarna och ute i församlingarna. Olika definitioner av ”Europa” presenteras, där inte bara Rysslands, utan också Storbritanniens tillhörighet ifråga
Calcium phosphates have been of great interest in the field of medicine for many decades due to their biocompatibility, hardening properties and diverse areas of application. In this study two different alpha phase tricalcium phosphate powders were produced of distinctly different particle size distributions. These two powders were then tested for reactivity and phase evolution. X-ray diffraction
This paper describes how attribute grammars can be used to integrate program visualization in language-based environments and how program visualizations can be specified and generated from grammars. It is discussed how a general solution for a simple grammar can be reused in grammars for other specific languages. As an example we show how diagram generation for a very simple state transition langu
The aim of the present study was to characterize the airway effects of U46619, a stable thromboxane A2 mimetic, instilled into the trachea of guinea pigs in vivo, and to investigate the role of different mediators in these effects. The airflow obstruction was evaluated by measurement of airway insufflation pressure (P1) and plasma extravasation by quantification of Evans Blue dye (EBD) in airways.
Background Oral anticoagulation (OA) is a common treatment with a known risk of fatal or major bleeding, but also minor bleeding symptoms and menorrhagia can cause substantial discomfort and necessitate medical or surgical interventions. The extent of these side effects is however not previously reported. The objective of this study is to assess the frequency of minor bleeding symptoms and menorrh
Religion and religious ideologies interact with other power structures in society. Therefore religious factors should be considered in intersectional analyses,along with factors such as class, gender and ethnicity. The suggested tool of religious proximity is, as an example, applied to an analysis of women as religious leaders in the context of religious fundamentalism.
The integrin CD103 is highly expressed at mucosal sites, but its role in mucosal immune regulation remains poorly understood. We have analyzed the functional role of CD103 in intestinal immune regulation using the T cell transfer model of colitis. Our results show no mandatory role for CD103 expression on T cells for either the development or CD4(+)CD25(+) regulatory T (T reg) cell-mediated contro
BACKGROUND: Patients with prosthetic heart valves have an increased risk of thromboembolic events, and transcranial Doppler sonography reveals microembolic signals. Whereas microembolic signals were initially assumed to be of particulate matter, recent studies suggest that they are partially gaseous in origin. If this is true, alteration of environmental pressure should change microembolic signal
Som journalist och fotograf var Lennart Williams framför allt knuten till Ljungby-Tidningen Smålänningen, men han publicerade sig flitigt som naturskribent även i många andra publikationer. Den här uppsatsen tar fasta på ett nostalgiskt tema i de naturkrönikor han skrev i Göteborgs-Posten under åren 1957-87.
First results on charm quarkonia production in heavy ion collisions at the Relativistic Heavy Ion Collider (RHIC) are presented. The yield of J/psi's measured in the PHENIX experiment via electron-positron decay pairs at midrapidity for Au-Au reactions at roots(NN) = 200 GeV is analyzed as a function of collision centrality. For this analysis we have studied 49.3x10(6) minimum bias Au-Au reactions
Cross sections for elastic production of J/psi mesons in photoproduction and electroproduction are measured in electron proton collisions at HERA using an integrated luminosity of 55 pb(-1). Results are presented for photon virtualities Q(2) up to 80 GeV2. The dependence on the photon-proton centre of mass energy W-gamma p is analysed in the range 40 <= W-gamma p <= 305 GeV in photoproduction and
