OBJECTIVE:: This study investigates the hypoperfusion effects of epinephrine in local anesthesia in eyelid surgery. A novel form of extended-wavelength diffuse reflectance spectroscopy was evaluated. METHODS:: Blood perfusion in porcine eyelid flaps was measured using laser Doppler velocimetry and laser speckle contrast imaging, whereas the tissue response was measured using diffuse reflectance sp

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
