Patients' experiences and perceived causes of persisting discomfort following day surgery

Background: The aim of this study was to describe patients' experiences and perceived causes of persisting discomfort following day surgery. Earlier research has mainly covered symptoms and signs during a recovery period of up to one month, and not dealt with patients' perceptions of what causes persisting, longer-term discomfort.Methods: This study is a part from a study carried out during the pe

Evaluation of the image quality of ink-jet printed paper copies of digital chest radiographs as compared with film : A receiver operating characteristic study

Paper copies of digital radiographs printed with the continuous ink-jet technique have proved to be of a high enough quality for demonstration purposes. We present a study on the image quality of ink-jet printed paper copies of digital chest radiographs, based on receiver operating characteristic (ROC) analysis. Eighty-three digital radiographs of a chest phatom with simulated tumors in the medias

Quantitative evaluation of tomographic 201-thallium myocardial scintigraphy

Myocardial 201Tl emission computed tomography was performed on 25 normal subjects and 27 patients with angiographically significant coronary artery disease. A semi-automatic computer program was designed to define the left ventricular myocardial volume in all short axis sections. Within this volume the relative mean myocardial pixel count was calculated. This parameter was found to separate the 2

What does it take to establish that a world is uninhabited prior to exploitation? – A question of ethics as well as science

If we find life on another world, it will be an extremely important discovery and we will have to take great care not to do anything that might endanger that life. If the life we find is sentient we will have moral obligations to that life. Whether it is sentient or not, we have a duty to ourselves to preserve it as a study object, and also because it would be commonly seen as valuable in its own If we find life on another world, it will be an extremely important discovery and we will have to take great care not to do anything that might endanger that life.

Lipase-catalyzed fatty acid exchange in digalactosyldiacylglycerol. Improvement of yield due to the addition of phenylboronic acid

Rhizopus arrhizus lipase immobilized on porous polypropylene was used in an acidolysis reaction in toluene at low water activity (0.11) to exchange the fatty acid in the sn-1-position of digalactosyldiacylglycerol (DGDG). Without extra precautions, an yield of only about 20% was obtained, mainly due to side reactions; incorporation of an extra acyl group on the primary hydroxyl of the digalactosyl

Diphoton production in the ADD model to NLO + parton shower accuracy at the LHC

In this paper, we present the next-to-leading order predictions for diphoton production in the ADD model, matched to the HERWIG parton shower using the MC@NLO formalism. A selection of the results is presented for d = 2-6 extra dimensions, using generic cuts as well as analysis cuts mimicking the search strategies as pursued by the ATLAS and CMS experiments.

Top quark phenomenology : An overview

In this talk three 2-sigma deviations from the Standard Model predictions in the top quark sector are briefly discussed. These are the excess of events in the tail of the H T distribution in tt events, the top-quark charge asymmetry and the discrimination of s- and t-channel events in single top. The latter has only been observed by CDF, while the other two are found by both CDF and DØ.

Effect of natural gas composition on the laminar burning velocities at elevated temperatures

Laminar burning velocities of fuel mixtures of methane/ethane/propane with the compositions 100/0/0, 80/20/0, 80/0/20 and 80/10/10 vol% burning with air were determined experimentally using the heat flux method at 1 atm and initial gas temperatures 298, 318 and 338 K. The mixtures were selected as surrogates for natural gas, with the aim to investigate the effect of heavier hydrocarbons on the la

Multiplicity dependence of (anti-)deuteron production in pp collisions at s=7TeV

In this letter, the production of deuterons and anti-deuterons in pp collisions at s=7 TeV is studied as a function of the charged-particle multiplicity density at mid-rapidity with the ALICE detector at the LHC. Production yields are measured at mid-rapidity in five multiplicity classes and as a function of the deuteron transverse momentum (pT). The measurements are discussed in the context of ha

Sound interventions : How to think about a place not yet

As a part of a democratic demand for transparency in urban development processes it is important that design professionals hold the ability to scrutinize their own work process, and at certain stages let go of predefined ideas of future realities. The work of Sandra Kopljar’s dissertation revolves around how design professionals perceive options for design in such situations. A basic assumption th

Manned Missions, Geoengineering and Planetary Protection : How Safe is Safe Enough?

If we ever decide to start geoengineering another world, and maybe even terraform a world that is not presently habitable for humans, it is also highly probable that it will become less habitable for any indigenous life. Making sure, or at least trying to determine the probability that a potentially habitable world is in fact uninhabited will thus be an important step before we start any geo-engin

Interpolation Between Hilbert Spaces

This note comprises a synthesis of certain results in the theory of exact interpolation between Hilbert spaces. In particular, we examine various characterizations of interpolation spaces and their relations to a number of results in operator theory and in function theory.

Nature’s services at risk in a changing climate

Climate change is increasingly posing a threat to biodiversity, both through its direct effects on organisms and through indirect effects resulting from changes in land use. Preserving biodiversity is an ethical obligation, but it is also increasingly being realised that biodiversity contributes to ecosystem services, i.e. ecosystem processes important for human needs and prosperity. In order to a
