Comorbidity burden is not associated with higher mortality after out-of-hospital cardiac arrest*

Objectives. We investigated whether comorbidity burden of comatose survivors of out-of-hospital cardiac arrest (OHCA) affects outcome and if comorbidity modifies the effect of target temperature management (TTM) on final outcome. Design. The TTM trial randomized 939 patients to 24 h of TTM at either 33 or 36 °C with no difference regarding mortality and neurological outcome. This post-hoc study of

14C bomb-pulse dating and stable isotope analysis for growth rate and dietary information in breast cancer?

The purpose of this study was to perform an initial investigation of the possibility to determine breast cancer growth rate with 14C bomb-pulse dating. Tissues from 11 breast cancers, diagnosed in 1983, were retrieved from a regional biobank. The estimated average age of the majority of the samples overlapped the year of collection (1983) within 3σ. Thus, this first study of tumour tissue has not

Early and Menopausal Weight Gain and its Relationship with the Development of Diabetes and Hypertension

Background: Previous research has revealed a clear relationship between weight gain of persons and their metabolic diseases developing later. These studies have covered only short periods lasting 4–8 years. Our goal was to collect decades’ old and often life-long anthropometric data and correlate the figures with the presence of hypertension and diabetes or both. Methods: A retrospective internat

Synchrotron-radiation soft-x-ray photoemission study of lead on Bi2CaSr2Cu2O8

In this paper we present a study of the interaction of Pb with a clean single-crystal Bi2CaSr2Cu2O8 superconductor surface based on photoemission and low-energy electron diffraction (LEED). Deposition of Pb on a Bi2CaSr2Cu2O8 crystal kept at room temperature gives rise to the formation of metallic Bi and oxidized Pb at the interface. This behavior could not be observed when the crystal was kept at

Electronic and structural properties of the Cu - Bi2CaSr2Cu2O8 interface

The formation of the Cu-Bi2CaSr2Cu2O8 interface has been studied by photoelectron spectroscopy using synchrotron radiation. Photon energies in the range 20-1000 eV were utilized in order to probe both the valence band and to monitor chemical changes upon Cu deposition, as revealed by the core-level shifts. A strong chemical reaction between Bi2CaSr2Cu2O8 and Cu is manifested by the formation of me

Surface core-level shifts as a probe of the local overlayer structure : CO on Pd(100)

The bonding energies of the Pd 3d and the C 1s core levels have been studied for the p(2 S 2 × 2) R45°, p(3 s2 × S2) R45°, and p(4 S 2 × S 2) R45°structures of CO on Pd(100). Adsorption of CO shifts the Pd 3d surface emission to higher binding energies with the magnitude of the shift depending almost linearly on the number of Pd to CO bonds; the measured shift per bond is close to 0.5 eV. A direct

Secondary photoelectron spectra of ionic solids as a function of the incident photon energy

Energy distributions of slow electrons (0-10 eV) emitted by thin layers of NaCl, KBr, CsBr, and CsI irradiated by monochromatic XUV photons with various energies in the interval of 50-300 eV are measured. The contributions of slow secondaries, hot secondaries and primary photoelectrons are obtained. It is shown that the higher the absorption coefficient for incident photons, the stronger the contr

The nature of an upscale nature : Bro Hof Slott Golf Club and the political ecology of high-end golf

Political ecology, as a perspective for exploring power-permeated socio-ecological transformations, has to date rarely engaged with tourism. Neither has tourism theory, with some notable exceptions, engaged much with political ecology. In this article, I argue that the resultant lack of dialogue between these signifies a loss for political ecology and tourism theory alike, but also that current co

Numerical methods for load and response prediction for use in acoustic fatigue

Acoustic fatigue can occur in structural elements of an aircraft exposed to very high sound pressures. To deal with acoustic fatigue, mainly empirical methods have been applied and often late in the design phase. Current design guidelines have three main limitations. First, they do not say anything about the load intensities. The load levels can be determined either experimentally or numerically.

Revisiting the role of selection for the evolution of industries

Despite a growing reliance on evolutionary theories when explaining industrial dynamics, the mechanism of selection has received limited attention. Selection is often taken for granted and conceptualised as product market competition. We go beyond this view and distinguish between different types of selection—formal and social—and consider how these lead to different entities being selected. Forma

New Big Science in Focus : Perspectives on ESS and MAX IV

This anthology is about new big science, approached through perspectives from law, sustainability studies, sociology of science and technology, history, human geography and information studies. In focus are the two large experimental facilities being built in Lund: the European Spallation Source (ESS) and MAX IV. Put centre stage are the communities that launch, build, use, host, and benefit from

Recoil-α-fission and recoil-α-α-fission events observed in the reaction 48Ca + 243Am

Products of the fusion-evaporation reaction 48Ca + 243Am were studied with the TASISpec set-up at the gas-filled separator TASCA at the GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt, Germany. Amongst the detected thirty correlated α-decay chains associated with the production of element Z=115, two recoil-α-fission and five recoil-α-α-fission events were observed. The latter five chains

Conduction mechanism of nitronyl-nitroxide molecular magnetic compounds

We investigate the conduction mechanisms of nitronyl-nitroxide (NIT) molecular radicals, as useful for the creation of nanoscopic molecular spintronic devices, finding that it does not correspond to standard Mott behavior, as previously postulated. We provide a complete investigation using transport measurements, low-energy, sub-THz spectroscopy and introducing differently substituted phenyl appen

A multilevel analysis of innovation in developing countries

Innovation is a multilevel phenomenon. Not only attributes of firms but also the framework conditions within which firms operate matter. Although this has been recognized in the literature for a long time, a quantitative test that explicitly considers this hypothesis has been lacking. Using a large sample of firms from many developing countries, we estimate a multilevel model of innovation which c

The establishment of facts in public discourse: Actor-Network-Theory as a methodological approach in PR-research

This article discusses actor-network theory (ANT) as an approach in empirical public relations research. It is foremost a methodological reflection, but uses a case study to illustrate key points. The case, published as a full study elsewhere, revolved around the plagiarisms in the PhD-dissertation of former German Defence Minister zu Guttenberg and places special emphasis on the work of anonymous
