We report low-temperature transport studies of parallel double quantum dots formed in GaSb/InAsSb core-shell nanowires. At negative gate voltages, regular patterns of Coulomb diamonds are observed in the charge stability diagrams, which we ascribe to single-hole tunneling through a quantum dot in the GaSb core. As the gate voltage increases, the measured charge stability diagram indicates the appe
Prediction from time-series data is traditionally accomplished using parametric, or at least structural, methods. For example, after removing trends, arguing that the time-series is an autoregression, and estimating the autoregressive parameters, we may predict future expected values, conditional on the past. In this paper, motivated by long meteorological maximum-temperature time-series, we sugge
Traditional gold mining, using metallic mercury (Hg-0) to form gold amalgam, followed by burning to remove the Hg-0, is widely used in South America, Africa and Asia. The gold is sold to merchants who burn it again to eliminate remaining Hg-0. In Ecuador, 200 gold miners, 37 gold merchants and 72 referents were studied. The median Hg concentrations in urine (U-Hg) were 3.3 (range 0.23-170), 37 (3.
Self-assembly of peptides and bile acids has been widely investigated because of their biological role and their potential as a tool for the preparation of nanostructured biomaterials. We herein report both the synthesis and the self-association behavior of a compound that combines the aggregation properties of bile acid- and amino acid-based molecules. The derivative has been prepared by introduc
Popular Abstract in Swedish Arbetsförmåga har kommit att bli ett viktigt begrepp i samhället, men också för individen. Det saknas i dag en tydlig definition av arbetsförmåga, trots att det har en stor inverkan på hur sjukförmåner distribueras och också för den enskilde individens möjlighet att försörja sig. I västvärlden är arbetsförmåga ofta diskuterat i relation till sjukskrivning och en åldrad The overall aim of this thesis was to deepen the understanding of work ability by analyzing how different health professionals experience and perceive work ability and assessments of work ability, and also by analyzing rehabilitation outcomes that are related to work ability. The focus has been on musculoskeletal disorders with associated psychosocial factors. Method. The general approach was indu
Measurements of open charm production cross sections in deep-inelastic ep scattering at HERA from the H1 and ZEUS Collaborations are combined. Reduced cross sections sigma(c (c) over bar)(red) for charm production are obtained in the kinematic range of photon virtuality 2.5 <= Q(2) <= 2000 GeV2 and Bjorken scaling variable 3 . 10(-5) <= x <= 5 . 10(-2). The combination method accounts for the corr
The Sound Environment Center at Lund university is an interdisciplinary center created to coordinate research on sound and soundscape issues and is known to be the first of its kind worldwide. Ranging from acoustics to medicine, psychology, and cognitive sciences, as well as humanities like musicology and linguistics, soundscape research adresses many interdependent areas and touches upon health a
Abstract in French Le monologue théâtral par l’auteur italien Alessandro Baricco, Novecento, publié en 1994 a fait l’objet de deux adaptations: en 1998 Giuseppe Tornatore a réalisé un film en langue originale anglaise, The Legend of the Pianist on the Ocean; en 2008, Baricco lui-même, en collaboration avec le dessinateur Giorgio Cavazzano et le scénariste Tito Faraci, signe l’adaptation en bandes
Three new copper(II) complexes, [Cu(L)(Cl)]ClO4 (1), [Cu(L)(Br)]ClO4 (2) and [Cu(L)(I)]ClO4 (3), have been prepared from a tetradentate symmetrical Schiff base, N,N'-bis-(1-pyridin-2-yl-ethylidene)-propane-1,3-diamine (L), and characterized by elemental analysis, IR and UV-Vis spectroscopy and single-crystal X-ray diffraction studies. Extended supra-molecular networks were generated through differ
Hemicelluloses could be used to replace fossil-based materials in several high-value-added products. Today, vast amounts of hemicelluloses are discharged from pulp mills all over the world as waste, but these could be isolated by membrane filtration, and utilized in various applications. In this study, the hemicellulose galactoglucomannan was isolated from process water from a thermomechanical pul
We observe spin-valve-like effects in nanoscaled thermally evaporated Co/AlO x /Au tunnel junctions. The tunneling magnetoresistance is anisotropic and depends on the relative orientation of the magnetization direction of the Co electrode with respect to the current direction. We attribute this effect to a two-step magnetization reversal and an anisotropic density of states resulting from spin-orb

Research in logistics and supply chain management typically considers transport activities between shippers (sender), carriers (transport operators) and customers (recipient). However, a closer look into real-world road freight transport systems reveals more complex constellations involving multiple actors with different functions, leading to a fragmentation of transport planning and control activ
Major intrinsic proteins (MIPs) form a large superfamily of proteins that can be divided into different subfamilies and groups according to phylogenetic analyses. Plants encode more MIPs than other organisms and seven subfamilies have been defined, whereof the Nodulin26-like major intrinsic proteins (NIPs) have been shown to permeate metalloids. In this chapter we review the phylogeny of MIPs in g
The combination of polyethylenimine (PEI), as a plasmid DNA pre-condensing agent, and cationic lipids has been reported to result in a synergistic effect on transfection. Recently, we have explored this effect by associating low-molecular weight PEIs with transferrin-associated lipoplexes using different cationic liposome formulations. The resulting lipopolyplexes that have shown to be the most ef
