Water exchange on Pt(H20)42+ and trans-PtCI2(H20)2 has been studied by means of a new oxygen18 tracing technique. The exchange between a platinum(II) complex and 018-enriched water has been rapidly quenched by addition of excess chlorine, which gives a substitution-inert platinum(IV) complex. The time-dependent oxygen16/oxygen18 distributions of the platinum(II) complexes are obtained from the 195

Mobile business intelligence (m-BI), an extension of business intelligence (BI), promises to support decision-making on the move. What is new and interesting about m-BI is the fact that users can access and analyse business information when needed independently of time and place on mobile devices such as smartphones and tablets. This is largely due to the mobile capabilities entailed in m-BI, such

Supramolecular rearrangements are crucial in determining the response of stimuli sensitive soft matter systems such as those formed by mixtures of oppositely charged amphiphiles. Here mixtures of this kind were prepared by mixing the cationic block copolymer pAMPTMA30-b-pNIPAAM120 and an anionic surfactant obtained by the modification of the bile salt sodium cholate. As pure components, the two co

The reactions in acidic aqueous solution between thiocyanate and each of the gold(II1) complexes Au(NH,)?+, rrans-Au- (NH,)zC12t, and rrans-A~(NH,)~Br~+ have been studied by use of potentiometric pH measurements and sequential-mixing stopped-flow spectrophotometry. The reactions give a common gold(1) product whereas the rate-controlling steps are different. The reaction between Au(NH,)?+ and thiocThe reactions in acidic aqueous solution between thiocyanate and each of the gold(III) complexes Au(NH3)43+, trans-Au(NH3)2C12+, and trans-Au(NH3)2Br2+ have been studied by use of potentiometric pH measurements and sequential-mixing stopped-flow spectrophotometry. The reactions give a common gold(I) product whereas the rate-controlling steps are different. The reaction between Au(NH3)43+ and thioc

The present report is a 'H NMR investigation of the dimethyl sulfoxide exchange on Pt(Me2S0)42+ as a function of temperature and pressure in CD3N02. Dimethyl sulfoxide is an ambidentate ligand, and the complex contains two 0-bonded and two S-bonded ligands that are exchanging with the free ligand at different rates. It is favorable to follow these exchanges in a non-coordinating diluent like nitro

Crystals of Pt(DMSO)4(TFMS)2 have been prepared by dissolution of platinum(II) hydroxide in a solution of CF3SO3H in DMSO and subsequent evaporation. The structure was determined by use of a CAD-4 diffractometer with monochromatic Mo Kα radiation. The space group is PFull-size image (Crystals of Pt(DMSO)4(TFMS)2 have been prepared by dissolution of platinum(II) hydroxide in a solution of CF3SO3H in DMSO and subsequent evaporation.

Purpose: Substance use disorders and problematic substance use are common problems in adolescence and young adulthood. Brief personalized feedback has been suggested for treatment of alcohol and drug problems and poor mental health. This repeated measurement randomized controlled trial examines the effect of an interactive voice response (IVR) system for assessing stress, depression, anxiety and s

Populärvetenskaplig sammanfattning:Dagens datorer har krympt i storlek i takt med den ständigt ökande kompetensen att tillverka transistorer med en anmärkningsvärd noggrannhet. Storleksskalan av nya transistorer börjar motsvara den av en handfull atomer.På denna skala dominerar kvantfysik, vilket är ett väsentligt hinder för de traditionella datorkomponenterna. Men detta innebär inte bara en begräThe work contained in this thesis deals with two closely related topics. Papers I-III deal with charge transport statistics in nanoscale devices to investigate the presence of entanglement in the constituent electrons. We identify the contributions of entangled electron pairs to the current cross-correlations as a signature of entanglement. Paper IV treats the electric control of a quantum dot bas

We investigate the effects of the orientation of the magnetic field and the orientation of a quantum dot, with respect to crystallographic coordinates, on the quality of an electrically controlled qubit realized in a gated semiconductor quantum dot. We find that, due to the anisotropy of the spin-orbit interactions, by varying the two orientations it is possible to tune the qubit in the sense of o

Barns internetanvändning äger i stor utsträckning rum i en kommersiell miljö där reklam och försäljning av virtuella föremål är ständigt närvarande. Genom att kombinera publikforskning, produktionsforskning samt textanalys (observationer online och dokumentanalys) bidrar denna avhandling till en kritisk förståelse av internet som en plats för barns vardagliga aktiviteter och deltagande, och som enChildren’s daily internet usage takes place to a large extent in a commercial environment, where advertising and the sale of virtual goods are ever-present parts of the online experience. The overall goal of this thesis is to contribute to a critical understanding of children’s commercial online environment as spaces for children’s everyday life activities and participation, and as spaces for comm
