Complex hydrides are very promising candidates for future light-weight solid state hydrogen storage materials. The present work illustrates detailed characterization of such novel hydride materials on different size scales by the use of synchrotron radiation and neutrons. The comprehensive analysis of such data leads to a deep understanding of the ongoing processes and mechanisms. The reaction pat

We report the structure of a novel tetrameric form of the lactose repressor (LacI) protein from Escherichia coli refined to 2.1 A resolution. The tetramer is bound to 1.6-hexanediol present in the crystallization solution and the final R(free) for the structure is 0.201. The structure confirms previously reported structures on the monomer level. However, the tetramer is much more densely packed. T

In Sweden, 13 % of all transport is related to business travelling, resulting in significant emissions of not only CO2, but also of NOx, VOC, CO and particle matter. The implication for business will not only come in the form of ecological impacts affecting the natural resource base; as people around the world wake up to the fact that issues, like climate change, are a real threat to their welfare

Many cluster studies have focused on growth regions and industries covering only the early phases of cluster development. Little attention, however, has been paid to the renewal of clusters in old industrial regions. The aim of the paper is to address the question of how clusters renew themselves in such regions and how they adjust to changes in their environment. After identifying relevant factor

The conservation law studied is partial derivative u(x,t)/partial derivative t + partial derivative/partial derivative x (F(u(x,t),x)) = s(t)delta(x), where u is a concentration, s is a source, delta is the Dirac measure, and is the flux function. The special feature of this problem is the discontinuity that appears along the t-axis and the curves of discontinuity that go into and emanate from it.

Thrombotic thrombocytopenic purpura (TTP) is a thrombotic microangiopathic disorder characterized by thrombocytopenia, hemolytic anemia, neurological and renal manifestations, and fever. It is associated with dysfunctional von Willebrand factor (VWF) proteolysis and the occurrence of VWF- and platelet-rich thrombi in the microcirculation of multiple organs, including the kidneys. Von Willebrand fa

Radio frequency identification (RFID) is a compelling technology for Internet of Things (IoT). Ultra-wideband (UWB) technology is one promising wireless technique for future RFID, especially for high-throughput sensing applications. On-off keying UWB RFID system provides high pulse rate but suffers severe collisions that limit the system throughput. This paper proposes to utilize low pulse rate co

The equations of motion for a beam are derived from the three-dimensional continuum mechanical point of view. The kinematics involve bending, torsion and shearing as well as cross-sectional displacements. The transplacement of the beam from an arbitrary curved reference placement is considered. For slender beams so called tubular coordinates may be used as global coordinates in the reference place

Oligomers of the amyloid-beta peptide (A beta) are thought to be the most toxic form of A beta and are linked to the development of Alzheimer's disease (AD). Here, we used a flow cytometric approach for the detection and assessment of oligomers in cerebrospinal fluid (CSF) from AD patients and other neurological disorders. 30 CSF samples from patients suffering from AD (n=14), non-demented control

This article describes the Survivable Network Design Library (SNDlib), a data library for fixed telecommunication network design available at http://sndlib.zib.de. In the current version 1.0, the library contains data related to 22 networks which, combined with a set of selected planning parameters, leads to 830 network design problem instances. In this article, we discuss the data concepts of SND

To support occupations outside the home for older people with functional limitations it is important to understand how the person, environment, and occupations influence performance. Therefore the purpose of this study was to describe how very old people experience occupational performance outside the home. Twenty-one single-living, very old persons, above 80 years, were strategically selected and

Two methods (including randomization) are studied for increasing the uncertainty concerning n ³ 1 transmitted messages and an applied key. Furthermore, it is shown that encryptions which perform equally well for n = 1 may perform differently when n > 1.
