The early crust of the Volgo-Uralian segment of the East European Craton: Isotope-geochronological zirconology of metasedimentary rocks of the Bolshecheremshanskaya Formation and their Sm-Nd model ages

We present the results of isotope-geochronological study of metasedimentary rocks of the Bolshecheremshanskaya Formation of the Volgo-Uralian segment of the East European Craton carried out to identify their protoliths. 16 samples of high-alumina gneisses from well cores were studied using the Sm-Nd isotope method and T-Nd(DM) model ages. Accessory zircons were selected from rocks with the most an

Measurement of colour flow with the jet pull angle in t(t)over-bar events using the ATLAS detector at root s=8 TeV

The distribution and orientation of energy inside jets is predicted to be an experimental handle on colour connections between the hard-scatter quarks and gluons initiating the jets. This Letter presents a measurement of the distribution of one such variable, the jet pull angle. The pull angle is measured for jets produced in t (t) over bar events with one W boson decaying leptonically and the oth

Band structure of segmented semiconductor nanowires

We have calculated the band structures for strained segmented nanowires involving all combinations of AlN, GaN, InN, AlP, GaP, AlAs, GaAs, InP, InAs, AlSb, GaSb, and InSb, as a function of segment length. This was done for two different growth directions of the wires, [100] and [111]. Both the Gamma and the X conduction-band minima were included in the calculations as well as the valence bands. Sh

Studies on the Interactions Between Mucin and Surfactant Aggregates Containing the Cationic Surfactant Dodecyl Betainate

The interactions of surfactant aggregates containing the cationic, cleavable surfactant dodecyl betainate (DB) with mucin are investigated. The aggregates were either mixed micelles of DB and the nonionic surfactant PS-80 in different ratios or a dispersion of the commercial self-emulsifying drug-delivery formulation Sandimmun Neoral charged with DB. It is found that for the surfactant aggregates

Du och jag men inte vi : om omöjliga möten och deras orsaker i J. M. Coetzees fiktion

Popular Abstract in Swedish Den sydafrikanske författaren J. M. Coetzee, nobelpristagare 2003, är en komplex författare som räknas till en av samtidens största. Han har en unik politisk hållning i sina romaner och vägrar konsekvent att ge några enkla lösningar, istället drar han in läsaren och tvingar henne att bli delaktig i verkens problematik. I denna studie, den första avhandlingen på svenska This dissertation is a study of In the Heart of the Country (1977), Waiting for the Barbarians (1980), Age of Iron (1990), Disgrace (1999), Diary of a Bad Year (2007), and Summertime (2009) written by J. M. Coetzee. The aim of the dissertation is to analyze these works of fiction using four postcolonial aspects that function as consistent themes in the novels. The aspects are; the relationship bet

Solving Quadratically Constrained Geometrical Problems using Lagrangian Duality

In this paper we consider the problem of solving different pose and registration problems under rotational constraints. Traditionally, methods such as the iterative closest point algorithm have been used to solve these problems. They may however get stuck in local minima due to the non-convexity of the problem. In recent years methods for finding the global optimum, based on Branch and Bound and c

Factors influencing Internet usage in older adults (65 years and above) living in rural and urban Sweden

Older adults living in rural and urban areas have shown to distinguish themselves in technology adoption; a clearer profile of their Internet use is important in order to provide better technological and health-care solutions. Older adults' Internet use was investigated across large to midsize cities and rural Sweden. The sample consisted of 7181 older adults ranging from 59 to 100 years old. Inte

Improvisation, Computers, and Interaction : Rethinking Human-Computer Interaction Through Music

Interaction is an integral part of all music. Interaction is part of listening, of playing, of composing and even of thinking about music. In this thesis the multiplicity of modes in which one may engage interactively in, through and with music is the starting point for rethinking Human-Computer Interaction in general and Interactive Music in particular. I propose that in Human-Computer interactio

Trade and aid? The negotiated construction of European Union policy on economic partnership agreements.

Efforts by the European Commission and by leading member states, to normatively frame the debate about trade - and thus rhetorically entrap other actors by references to previous commitments - are ubiquitous; and member states do take account of the potential effects of their actions, in terms of potential praise or shaming, and adapt their behaviour to the institutional setting. However, this hol

Development and validation of GFR-estimating equations using diabetes, transplant and weight

Methods. Linear regression was used to relate log-measured GFR (mGFR) to sex, race, diabetes, transplant, weight, various transformations of creatinine and age with and without interactions. Equations were developed in a pooled database of 10 studies [2/3 (N = 5504) for development and 1/3 (N = 2750) for internal validation], and final model selection occurred in 16 additional studies [external va

Stärkande samtal : fyra fallstudier av invandrarfamiljers läkarbesök i barndiabetesvården

I denna rapport redovisas en studie av kommunikationsmönster och strategier i konsultationer inom barndiabetesvården. En utgångspunkt för studien är att samtalsstrategier för att stödja upplevelsen av tilltro till sin förmåga att utföra vården av barnet kan urskiljas på mikronivå i samtalet. Fyra läkarkonsultationer inom barndiabetesvården har spelats in, transkriberats, analyserats och kompletter

Synthesis, characterization and antimalarial activity of new chromium arene-quinoline half sandwich complexes.

Organometallic analogs of chloroquine (CQ) are of interest as drug candidates that may be able to overcome the widespread chloroquine resistance developed by malaria parasites. Two new chromium arene CQ-analogs: [η(6)-N-(7-chloroquinolin-4-yl)-N'-(2-dimethylamino-methylbenzyl)-ethane-1,2-diamine]tricarbonylchromium 4 and [η(6)-N-(7-chloroquinolin-4-yl)-N'-(2-dimethylaminobenzyl)-ethane-1,2-diamine
