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
Den okritiske läsaren kan få uppfattningen att det råder konsensus om definitionen av begreppet livsstil med samma exakthet som en medicinsk diagnos. Så är ingalunda fallet. Det är oftare så att det är det slarviga bruket av ordet livsstil som gjort det så välbekant för en större allmänhet. Begreppet livsstil kommer här att analyseras i efter två huvudlinjer. Den ena har sin grund i empirisk forsk
This paper investigates a variety of forms of management control in a large management consultancy company. The very high level of compliance with corporate objectives among employees is highlighted and singled out as a phenomenon worth exploring. The company exhibits a rich variety of various formal control devices focusing on financial issues as well as human resources. The paper shows that thes
We study the history of storminess in Northern Europe, as derived from local pressure observations in Lund since 1780 and Stockholm since 1820 ( Sweden). At both stations barometer readings were made three times per day, morning, midday and evening, and after about 1850 at fixed observation hours. We use four common storminess indices: annual number of deep lows ( p < 980 hPa), the annual 95th and
