Bi-isonicotinic acid adsorption on rutile TiO2(1 1 0) surfaces has been studied using periodic first principles density functional calculations. The geometry of a dissociatively bridge-bonded adsorbate has been optimized, and the influence of the position of the dissociated protons on the surface examined. The results are in agreement with published experimental information on the adsorption geome

Background: Rheumatoid arthritis is associated with increased cardiovascular mortality and morbidity. Objective: To assess the effect of severe extra-articular rheumatoid arthritis (ExRA) manifestations on the risk of cardiovascular disease (CVD) in patients with rheumatoid arthritis. Methods: Patients with ExRA (n = 81) according to predefined criteria and controls (n = 184) without evidence of e

Popular Abstract in Swedish Avhandlingen handlar om islamisk predikokonst i teori och praktik, med särskilt fokus på islamisk predikan inspelad och publicerad på ljudkassett. Huvudmaterialet består av fyra kassetter med inspelningar av predikningar på arabiska: 1) Ismail Hamidi, ”Underrättelsen om uppståndelsens dag”; 2) Ahmad al-Qattan, ”Vägen till Paradiset/Lustgården”; 3) Ahmad al-Qattan, ”BeräThe dissertation deals with Islamic preaching in theory and practice, with special focus on material recorded and published in the format of audiotapes/cassettes. One aim is to explore possible implications of the use of this special format of publication in the context of Islamic preaching. How is this new format of publication to be understood in relation to the norms regulating the activity of

This thesis describes two different measurement methods applied to ultrasound. The first method, Ultrasound doppler vector tomography, uses ultrasound to measure blood flow and the second method, Light diffraction tomography, measures the pressure field in an ultrasound beam with laser light. Both methods depend on tomography algorithms for reconstruction of the measured region. A prime motive fo

Popular Abstract in Swedish Målsättningen med avhandlingen är att analysera vilken roll småskaligt entreprenörskap som alternativ överlevnadsstrategi har spelat i Sierra Leone under den ekonomiska kris som drabbade landet efter självständighet på 1960-talet. Avhandlingen baseras på nätverksteori, snowball metod och det empiriska underlaget utgörs av en studie av utvecklingen i Sierra Leone, med avSierra Leone is a small country with rich mineral resources such as diamonds, bauxite, gold and iron ore. Other resources include fishing, forestry and fertile agricultural land, which enable people to farm without any sophisticated methods of mechanization. Nevertheless, with all its wealth in resources, the country is relatively poor and is one of the least developed countries in the Sub-Saharan

Measurements are reported of the production of dijet events with a leading neutron in ep interactions at HERA. Differential cross sections for photoproduction and deep inelastic scattering are presented as a function of several kinematic variables. Leading order QCD simulation programs are compared with the measurements. Models in which the real or virtual photon interacts with a parton of an exch

In order to analyze whether loci in the human leukocyte antigen (HLA) class I region may contribute to the HLA class II-associated genetic susceptibility to multiple sclerosis (MS), we examined selected microsatellite markers in 177 Nordic sib-pair families, 222 British sib-pair families, 323 sporadic Norwegian MS patients and 386 Norwegian controls. All samples were, in addition, genotyped for th

A concentrating photovoltaic wall element, including Cu(In, Ga)Se-2-based modules, aluminum reflectors, and an insulation for building integration, has been developed and evaluated. The geometric concentration ratio of the system is about 3 x. However, the measured maximum electric power from the modules is only 1.9 times that of identical vertical modules without reflectors, due to optical losses

The fusion-evaporation reaction involving a 175 MeV S-36 beam and a Sn-124 target was performed, and the emitted gamma rays were observed with the Gammasphere spectrometer. Significant additions to the level scheme of Gd-152 were made in spite of the relative weakness of the alpha 4n exit channel, being only similar to 2% of the total fusion cross-section. The high-spin behavior of Gd-152 was comp

This thesis is about self-knowledge, self-regulation and self-control. All three of these terms are easily understandable, and apply to situations in our daily lives (like misjudging one’s own competence at retiling the bathroom floor, or feeling the anxiety and thrill of doing unsupervised work, or guiltily hitting the snooze-button for the fifth time, and missing half a day of school). The five

Transient cerebral ischemia following I to 2 hours of middle cerebral artery occlusion (MCAO) in the rat leads to infarction, which can be diminished by synaptic transmission modulators, implying aberrant cell signaling in the pathogenetic process. The authors report here changes in the levels of tyrosine phosphorylated proteins (PTyr) and calcium calmodulin kinase II (CaMKII) phosphorylation of T

Ibuprofen, a non-steroidal anti-inflammatory drug, exhibited antimicrobial activity against Candida albicans and non-albicans strains. At 10 mg/ml, ibuprofen showed a rapid cidal activity against exponential growth phase C. albicans, accompanied by rapid and extensive leakage of intracellular K+, permeation to propidium iodide, lysis of spheroplasts and severe membrane ultrastructural alterations.

Varactors for continuous frequency tuning are typically used in LC-oscillators. However, they have some drawbacks for large tuning-ranges, such as high tuning sensitivity causing high sensitivity to noise and disturbances on the control voltage. Furthermore, large metal-oxide-semiconductor (MOS) varactors have high conversion of harmless amplitude noise into harmful phase noise. To reduce these pr

Regular octahedral coordination has been reported for some copper(II) complexes in the solid state on the basis of crystallographic studies, e.g. hexaaquacopper(II) bromate, [Cu(OH2)(6)](BrO3)(2). hexaaquacopper(II) hexafluorosilicate, [Cu(OH2)(6)]Si-6, and hexakis(pyridine-1-oxide)copper(II) perchlorate. [Cu(ONC5H5)(6)](ClO4)(2). These results are not consistent with the elongated octahedral conf

Popular Abstract in Swedish Polyomavirus är en familj av små DNA-virus som har onkogena egenskaper i försöksdjur i celler in vitro. De humana polyomavirusen BK virus (BKV) och JC virus (JCV) infekterar en stor del av befolkningen. Ungefär 70-80 % av vuxna är seropositiva, har antikroppar mot BKV och JCV. Primär infektion inträffar oftast under barndomen och är ofta subklinisk. Efter primära infektThe human polyomaviruses BKV and JCV are endemic and infect > 70% of population worldwide. Primary infections occur during childhood and are largely subclinical. Following primary infection, both viruses persist as latent infections in the kidneys and B lymphocytes. Under conditions of severe immunosuppression like leukaemia, organ transplantation and AIDS, the viruses can reactivate and cause dis
