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

This report contains derivations of a rigid double-track ground vehicle model including roll and pitch dynamics, using a Newton-Euler modeling approach. Suspension is incorporated in the model. The suspension system is modeled as a rotational spring and damper system, where the spring and damper constants for each wheel have been lumped to two constants, one for each degree of freedom. The resulti

Objectives. To investigate the caries risk profiles in young adults and to compare the risk classification using the Public Dental Service (PDS) guidelines with a risk assessment program, the Cariogram. Materials and methods. All 19-year-old patients registered at eight public dental clinics were invited to participate (n = 1699). The study group who completed the baseline examination consisted of

Abstract in UndeterminedThis paper addresses the failure of activation programmes to achieve a rapid return to work when they are directed towards the long-term ill. The empirical basis for the paper is an analysis of the outcomes for 691 individuals in Sweden chosen for a re-activation policy programme to shorten their sick leave and increase their chances of returning to work. The outcome at the

We discuss and compare four fixed parameter algorithms for finding the minimum weight triangulation of a simple polygon with (n - k) vertices on the perimeter and k vertices in the interior (hole vertices), that is, for a total of n vertices. All four algorithms rely on the same abstract divide-and-conquer scheme, which is made efficient by a variant of dynamic programming. They are essentially ba
