Intracardiac blood flow is driven by hemodynamic forces that are exchanged between the blood and myocardium. Previous studies have been limited to 2D measurements or investigated only left ventricular (LV) forces. Right ventricular (RV) forces and their mechanistic contribution to asymmetric redirection of flow in the RV have not been measured. We therefore aimed to quantify 3D hemodynamic forces
Background and purpose — Previous reports on elbow injuries with concomitant comminute radial head fracture are difficult to interpret, since they include an array of different soft-tissue and bony injuries around the elbow. We focused on Mason-IV fracture dislocations of the elbow and retrospectively reviewed 2 treatment options: radial head resection or replacement with a radial head arthroplast
Soon after the annexation of Crimea by the Russian Federation in March 2014, a peak moment in the events commonly referred to as the Ukraine crisis (Wilson A, Ukraine crisis. What it means to the West? Yale University Press, New Haven, 2014), media in Estonia and abroad started to speculate about whether Russia would stop at Crimea, or if Estonia, with its sizable Russian-speaking minority, would
Ni-YSZ (nickel - yttria stabilized zirconia) is a material widely used for electrodes and supports in solid oxide electrochemical cells. The mechanical and electrochemical performance of these layers, and thus the whole cell, depends on their microstructure. During the initial operation of a cell, NiO is reduced to Ni. When this process is conducted under external load, like also present in a stac
I denna publikation karakteriseras riskhanteringsprocessen som bestående av 14 olika steg och varje steg beskrivs och diskuteras. Även utvidgade aspekter på riskhanteringsprocessen samt riskhanteringens ekonomiska betydelse behandlas.Dagens moderna samhälle är ett i många avseenden sårbart samhälle till stor del uppbyggt kring försörjningskedjor (supply chains).

Dagens moderna samhälle är ett i många avseenden sårbart samhälle. Det har inte varit någon medveten strävan utan är en konsekvens av att samhället till stor del kommit att bli uppbyggt kring försörjningskedjor (supply chains). I dessa hårt integrerade kedjor med ett flertal ofta globalt utspridda led flyter en ständig ström av fysiska varor, tjänster samt kombinationer av varor och tjänster.I den
We demonstrate an artificial three-dimensional (3D) electrical active human neuronal network system, by the growth of brain neural progenitors in highly porous low density electrospun poly-ε-caprolactone (PCL) fiber scaffolds. In neuroscience research cell-based assays are important experimental instruments for studying neuronal function in health and disease. Traditional cell culture at 2D-surfac
The main focus of the work presented in this thesis is on experimental studies oflaser acceleration of protons and other positive ions from solid targets. The topic is explored from three different angles: firstly, the development of diagnostics adapted to the ion pulses, secondly, the characterization of the source of the energetic particles and, finally, the application of laser-accelerated prot
The performance of X-ray and neutron grating interferometers is characterised by their visibility, which is a measure for the maximum achievable contrast. In this study we show how the real grating geometry in a grating interferometer with three gratings impacts the interference and self projection that leads to visibility in the first place. We quantify the individual contributions of wavelength
In his study of Carl Michael Bellman literary historian Gustaf Ljunggren (1823-1905) compared the Swedish poet not only to the traditional object of comnaprison, the ancient Greek poet Anacreon, but also to the Persian fourteenth-century poet Hafiz.This article revisits Ljunggren's work in light of recent discussions about world literature and the role of historical scale in literary studies.

Introduction The Göttingen minipig is a promising model for pharmacological safety assessment and for translational research in cardiology. We have examined the main ion currents in cardiomyocytes of the minipig heart. Methods Cardiac cells were isolated from different cardiac regions (endo-, mid- and epicardial left ventricle and right ventricle) from Göttingen minipigs and examined using the who
Den svenska föreningen för tillämpad språkvetenskap (Association Suédoise de Linguistique Appliquée, ASLA) bildades formellt i april 1966 och firade således 50 år som förening under 2016. Jubileumet uppmärksammades på olika sätt under året. I samband med ASLA-symposiet i Uppsala den 21-22 april 2016 hölls ett panelsamtal på temat om tillämpad språkvetenskap då, nu och i framtiden.

This thesis makes a contribution the econometrics of panel data with cross-section dependence (CSD). It consists of five self-contained papers. The most popular approach to account for CSD is to attribute the co-movements of observed variables across entities to unobserved common factors and to estimate these factors via simple cross-section averages of the data. The chapters in this thesis invest
Preeclampsia is a serious pregnancy-specific condition, affecting 10 million women annually worldwide. No specific treatment is currently available. Recent studies have demonstrated abnormal production and accumulation of free fetal hemoglobin in the preeclamptic placenta, and identified subsequent leakage into the maternal circulation as an important factor in the development of preeclampsia.
