Experimental results on the acceleration of protons and carbon ions from ultra-thin polymer foils at intensities of up to 6x10(19)Wcm(-2) are presented revealing quasi-monoenergetic spectral characteristics for different ion species at the same time. For carbon ions and protons, a linear correlation between the cutoff energy and the peak energy is observed when the laser intensity is increased. Pa

This paper analyses biofuels from agricultural crops in northern Europe regarding area and energy efficiency, greenhouse gases and eutrophication. The overall findings are that direct land use changes have a significant impact on GHG balances and eutrophication for all biofuels, the choice of calculation methods when by-products are included affecting the performance of food crop-based biofuels co

Many nocturnal insects depend on vision for daily life and have evolved different strategies to improve their visual capabilities in dim light. Neural summation of visual signals is one strategy to improve visual performance, and this is likely to be especially important for insects with apposition compound eyes. Here we develop a model to determine the optimum spatiotemporal sampling of natural s

Three-dimensional direct numerical simulation with detailed chemical kinetics of lean premixed CH4/air and H-2/air flames at high Karlovitz numbers (Ka similar to 1800) is carried out. It is found that the high intensity turbulence along with differential diffusion result in a much more rapid transport of H radicals from the reaction zone to the low temperature unburned mixtures (similar to 500 K)

Women are stereotypically perceived as worse negotiators than men, which may make them ask for less salary than men when under stereotype threat (Kray et al., 2001). However, the mechanisms of stereotype threat are not yet properly understood. The current study investigated whether stereotype threat effects in salary negotiations can be explained by motivational factors. A total of 116 business st

We establish equality between the essential spectrum of the Schrödinger operator with magnetic field in the exterior of a compact arbitrary dimensional domain and that of the operator defined in all the space, and discuss applications of this equality.

The best results after a nerve injury with a defect are achieved by a nerve reconstruction procedure using autologous nerve grafts. However, limitations include insufficient amount of suitable donor material and donor site morbidity. The aim of the present thesis was to study alternative nerve grafts, i.e. allo- and xenografts, in rats and mice. Cellular grafts will evoke a rejection in the hos

A first comparison has been made between the pulse-shape discrimination characteristics of a novel He-4-based pressurized scintillation detector and a NE-213 liquicl-scintillator reference detector using an Am/Be mixed-field neutron and gamma-ray source and a high-resolution scintillation-pulse digitizer. In particular, the capabilities of the two fast neutron detectors to discriminate between neu

Compact arrays such as multiple antennas on a mobile terminal suffer from low efficiency and high correlation between antenna signals. In the present paper, a simple and rigorous procedure for decoupling two closely coupled antennas with a parasitic scatterer is proposed. The parasitic scatterer, which can be an additional antenna, acts as a shield between two active antenna elements. In contrast

Background-Late mortality after repair of total anomalous pulmonary venous connection is frequently associated with pulmonary venous obstruction (PVO). We aimed to describe the morphological spectrum of total anomalous pulmonary venous connection and identify risk factors for death and postoperative PVO. Methods and Results-We conducted a retrospective, international, collaborative, population-bas

Purpose - The purpose is to investigate how a retailer identifies critical network actors and gains their support when entering an emerging market. and to examine the role of a firm's relationships with different types of actors on the new market. Design/methodology/approach - The study is of an exploratory nature, and based on an inductive and qualitative research method. A case study of IKEA's e

Physiological and psychosocial factors might contribute to differences in weight loss, eating behaviour and health-related quality of life (HRQoL) after bariatric surgery. The aim of this study was to investigate how perceived control over eating changes after bariatric surgery and whether it affects outcome in super-obese patients. In a retrospective analysis of a prospective study (n = 60), 49 p

The global speed of change within the manufacturing industry forces companies to constantly improve production performance. In that effort, performance measures are critical for driving and managing production improvements. Two of the most commonly used measures in operations are productivity and overall equipment efficiency (OEE). However, the potential of using these measures as improvement driv

Resetting of epigenetic marks, such as DNA methylation, in germ cells or early embryos is not always complete. Epigenetic states may therefore persist, decay or accumulate across generations. In spite of mounting empirical evidence for incomplete resetting, it is currently poorly understood whether it simply reflects stochastic noise or plays an adaptive role in phenotype determination. Here, we u

For a level scheme investigation of Gd-142 an experiment with the gamma -spectrometer EUROBALLIII has been carried out and lifetimes have been measured with EUROBALL IV using the Doppler-shift attenuation method. The high-spin states have been populated in these experiments by means of the(99)Ru(Ti-48, 2p3n) reaction at a beam energy of 240MeV and the Sn-114(S-32, 2p2n) reaction at 160MeV, respect

The purpose of this study is to examine the extent to which Swiss companies engage in corporate entrepreneurship. To that end, a case study was undertaken to better understand how corporate entrepreneurship is practiced in the watch-making industry. Using a stratified sampling method, 18 corporate-level managers of Swiss watch manufacturers were interviewed over a 5-month period to determine their

Background: The addition of anthracyclines to platinum-based chemotherapy may provide benefit in survival in ovarian cancer patients. We evaluated the effect on survival of adding epirubicin to standard carboplatin and paclitaxel. Patients and methods: We carried out a prospectively randomized phase III study comparing carboplatin plus paclitaxel (TC; area under the curve 5 and 175 mg/m(2)) with t

Closer examination of material of Macrorrhyncha rostrata Zetterstedt, 1851 from Sweden revealed a mixture of two closely related species of which one, M. hugoi sp. n. is described based on type material from Southern Sweden and Southern England. The new species includes all known records of M. rostrata from England and the Channel Islands. Records of M. rostrata from continental Europe need to be

The purpose of this paper is to analyse the recent changes in the forms of representation of workers and citizens in a historical and comparative perspective. The issue of exclusion from representation has been important for a long time among social scientists both with reference to citizen’s rights and to trade union coverage of insiders and outsiders. This issue became more important in the rece
