Operators on unbounded domains may acquire eigenvalues that are embedded in the essential spectrum. Determining the fate of these embedded eigenvalues under small perturbations of the underlying operator is a challenging task, and the persistence properties of such eigenvalues are linked intimately to the multiplicity of the essential spectrum. In this paper, we consider the planar bilaplacian wit
The 7Be fragments produced in one-proton removal from relativistic 8B nuclei of 936 MeV/nucleon in a carbon target have been detected in coincidence with γ rays emitted by these fragments at the reaction target. It is found that 13 ± 3% of the 7Be fragments are released in the 429 keV excited state, 7Be*, which gives direct experimental information on the ground state configuration of 8B. The long
The refugee crisis is also a crisis in education. While attention is frequently directed toward primary and secondary school levels, higher education is a strategic issue for refugees, both as individuals and for long term processes of post-conflict recovery and peacebuilding. Education prospects and content are drivers of onwards migration, but also affect economic structures on return. Higher ed
This paper introduces means for fatigue damage rates estimation using Laplace distributed multiaxial loads. The model is suitable for description of stresses containing transients of random amplitudes and locations. Explicit formulas for computing the expected value of rainflow damage index as a function of excess kurtosis are given for correlated loads. A Laplace model is used to describe variabi
This essay investigates one of the Naqshbandi-Haqqani Sufi order's centres in London. Sociological theories on New Social Movements are introduced as a means of understanding the activities of the participants at the Sufi centre. Several topics and activities from the centre are presented, among them meditation rituals, physical training and aspects of the relationship between the order's sheikh a
This article outlines a numerical study on the benefit of using High-Performance/Strength Concrete for fabrication of concrete elements. For this purpose a comparison is done between the cost of existing beams with normal strength concrete and optimized beams made of High-Performance/Strength Concrete. A background is given concerning the most essential properties of High-Performance/Strength Conc
A radiocarbon-dated sediment sequence from Lake Berkut in the southern part of the Kola Peninsula, northwest Russia, was investigated by means of midge analysis in order to reconstruct the Holocene climatic and environmental history of the region. Past mean July air temperatures at the study site and hypolimnetic oxygen contents of the lake water were inferred from chironomid-based transfer functi
Colonial birds often demonstrate considerable breeding synchrony. In southern Sweden the semi-colonial European starling initiated the vast majority of clutches within one week. Laying dates were positively skewed so that many birds initiated clutches at similar dates early in the season. Breeding was further synchronised by a particularly strong clutch-size reduction equivalent to one third of an
The infrared spectrum of the complex between o-H-2 and H2O, D2O, or HDO, isolated in a matrix of solid p-H-2, has been studied between 20 and 4500 cm(-1). In addition the infrared spectrum of the complex between p-D-2 and H2O in solid o-D-2 has been studied. The spectral shifts are interpreted as the result of the quadrupole-dipole interaction between hydrogen and water. (c) 2006 American Institut
Some future directions for mycorrhizal research are discussed. Data from The IPCC Third Assessment Reports 2001 on elevated carbon dioxide the concentration and consequences regarding global climate change, form the basis for arguments that a better understanding of the mycorrhizal activities with regard to controlling carbon flow and plant nutrient flow is essential. Mycorrhiza can be regarded as
The NorduGrid project operates a production Grid infrastructure in Scandinavia and Finland using own innovative middleware solutions. The resources range from small test clusters at academic institutions to large farms at several supercomputer centers, and are used for various scientific applications. This talk reviews the architecture and describes the Grid services, implemented via the NorduGrid
Charge balance functions reflect the evolution of charged pair correlations throughout the stagesof pair production, dynamical diffusion, and hadronization in heavy-ion collisions. Microscopic mod-eling of these correlations in the full collision volume shows that the balance functions are sensitiveto the diffusivity of light quarks when studied as functions of relative azimuthal angle.
