The cerebral ischemia that occur after a subarachnoid hemorrhage (SAH) often results in death or severe disability and is a significant cause of stroke. Our hypothesis is that cerebral ischemia leads to pathophysiological receptor changes on the vascular smooth muscle cells. The changes may lead to a stronger vasoconstriction than normal in response to endogenous ligands. We are focusing on the en
A common control technique for limiting nitrogen oxide emissions is selective catalytic reduction (SCR) of NO, with NH,. The lifetime of the catalyst, which has a critical role in overall SCR system economics, is, however, limited due to deactivation by poisoning. A two-dimensional model was developed to describe poison accumulation and activity of an SCR catalyst. The model that has no adjustable
In an investigation conducted by the Swedish Cancer Society. the present status, critical issues and future aspects and potentials were described by expert group for each of nine major areas of radiation therapy research. In this report, research and development in radiation therapy clinical routines is described. The terms research, development, quality assurance, quality control and clinical rou
This paper treets the acquisition, variation and historical change in the use of the article with kinship names in Italian, or more precisely, the Florentine variety of Italian. The development in acquisition data and historical texts is compared regarding the use of the definitive article together with kinship nouns. The children studied in this paper classify DPs in non-target-like ways apparent
Artikel om kritiken av Lunds universitets studentdatorprojekt från utvärderaren Conny Svenning.
Popular Abstract in Swedish Vad är ett orsakssamband? Och vad är en orsak? Författaren hävdar att orsakssamband är lika verkliga och lokala som dess orsaker och effekter. Denna position är diametralt motsatt synen att orsakssamband i den mån de alls kan sägas finnas är instanser av lagbundenheter; en syn som (med viss orätt) tillskrivs David Hume, och som sedan dennes Treatise (1739) under långa tThe thesis addresses the nature of causation. It is argued that causation exists and is as local as its causes and effects. As a consequence, the position advocated is contrary to the as yet prevailing view that no 'causal tie' between cause and effect exists. Moreover, it is suggested that this tie can be perceived. The essay attempts to elucidate the nature of causes, effects, and causal mechani
We present calculations of autoionization widths using a fully numerical multiconfigurational Hartree-Fock method (MCHF). Energy positions and autoionization rates are given for several doubly-excited states lying below the n = 2 threshold in He I and H-. Particular attention is given to orthogonality considerations in the computation of the autoionization widths. The method is extended to the 1s2
We present and discuss new determinations of metallicity, rotation, age,kinematics, and Galactic orbits for a complete, magnitude-limited, andkinematically unbiased sample of 16 682 nearby F and G dwarf stars. Our∼63 000 new, accurate radial-velocity observations for nearly 13 500stars allow identification of most of the binary stars in the sampleand, together with published uvbyβ photometry, Hipp
The size and power of various generalization of the RESET test for functional misspecification are investigated, using the “Bootsrap critical values”, in systems ranging from one to ten equations. The properties of 8 versions of the test are studied using Monte Carlo methods. The results are then compared with another study of Shukur and Edgerton (2002), in which they used the asymptotic critical
Streptococcus agalactiae (group B Streptococcus) is the major cause of invasive bacterial disease, including meningitis, in the neonatal period. Although prophylactic measures have contributed to a substantial reduction in the number of infections, development of a vaccine remains an important goal. While much work in this field has focused on the S. agalactiae polysaccharide capsule, which is an
A Catalyst pharmacophore model has been developed for the benzodiazepine site within the GABA(A) receptor complex. The model is based on a pharmacophore model originally proposed by Cook and co-workers (Drug Des. Discovery 1995, 12, 193-248) and further developed by Kahnberg et al. (J. Med. Chem. 2002,45, 4188-4201). The Catalyst pharmacophore model has been validated by using a series of flavonoi
The expression and distribution of mRNA encoding preproatrial natriuretic peptide (ppANP) in rat brain has been investigated by in situ hybridization of two 35S-labeled synthetic DNA oligonucleotides, based on a cDNA clone sequence that encodes rat ppANP. The highest relative concentrations of ppANP mRNA were detected in the medial preoptic hypothalamic nucleus ("anteroventral/third ventricle regi
Formation of DNA adducts as a result of exposure to polycyclic aromatic hydrocarbons (PAH) was studied in 98 potroom workers from an aluminium smelting plant and in 55 blue-collar workers without occupational PAH exposure. DNA from peripheral blood mononuclear cells (PBMC) was used for quantitation of individual PAH-DNA adducts by P-32-postlabelling/high performance liquid chromatography (HPLC) an
Direct scattering of propagating transient waves originating from internal sources in non-stationary, inhomogeneous, dispersive, stratified media is investigated. The starting point is a general, inhomogeneous, linear, first order 2 X 2 system of equations. Particular solutions are obtained, as integrals of fundamental waves from point sources distributed throughout the medium. First, resolvent ke
