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
New records of the vinegar fly Cacoxenus indagator Loew, 1858 are reported from Sweden. The species was collected from two sites in Lund, Scania in 2014. The fly is known as a cleptoparasite of mason bees, Osmia spp., Megachilidae. The female Cacoxenus patrols around the nests of the bees, and lays eggs inside the broodcell, when the bee leaves for provisioning.
Biological tissues possess the ability to adapt according to the respective local loading conditions, which results in growth and remodelling phenomena. The main goal of this work is the development of a new remodelling approach that, on the one hand, reflects the alignment of fibrous soft biological tissue with respect to representative loading directions. On the other hand, the continuum approac
Solid tumors are less oxygenated than their tissue of origin. Low intra-tumor oxygen levels are associated with worse outcome, increased metastatic potential and immature phenotype in breast cancer. We have reported that tumor hypoxia correlates to low differentiation status in breast cancer. Less is known about effects of hypoxia on non-malignant cells. Here we address whether hypoxia influences
Theoretical and empirical research often points to a positive relation between corporate sustainability and organisational performance; however, attempts to conceptualise the multi-dimensional nature of sustainability practices are rare in the current literature. Thus, the purpose of this paper is to present a conceptual framework to aid in understanding and explaining the relationship between sus
A measurement of the cross section of top quark pair production in proton-proton collisions recorded with the ATLAS detector at the Large Hadron Collider at a centre-of-mass energy of 7 TeV is reported. The data sample used corresponds to an integrated luminosity of 2.05 fb(-1). Events with an isolated electron or muon and a tau lePton decaying hadronically are used. In addition, a large missing t
BACKGROUND—Software Process Improvement (SPI) is a systematic approach to increase the efficiency and effectiveness of a software development organization and to enhance software products. OBJECTIVE—This paper aims to identify and characterize evaluation strategies and measurements used to assess the impact of different SPI initiatives. METHOD—The systematic literature review includes 148 papers p
OBJECTIVE-Mutations in the hepatocyte nuclear factor (HNF)-1 alpha, HNF-4 alpha, glucokinase (GCK), and HNF-1 beta genes cause maturity-onset diabetes of the young (MODY), but it is not known whether common variants in these genes predict future type 2 diabetes. RESEARCH DESIGN AND METHODS-We tested 14 previously associated polymorphisms in HNF-1 alpha, HNF-4 alpha, GCK, and HNF-1 beta for associa
The design and fabrication of a home-made thin-layer electrochemical flow cell are reported. The performance and electrochemical characteristics of thin-layer cells are evaluated in terms of flow rate and channel thickness. The adaptability of the flow cell for amperometric and electrochemiluminescence measurements is demonstrated. Also, a flow injection method comprising electrochemical generatio
Background: It is important to clarify nurses' perceptions of conditions for patient education in daily work as research findings are ambiguous. There is a gap between societal regulations on nurses' competence in accomplishment/achievement of patient education and research findings. Aim: The aim was to describe nurses' perceptions of conditions for patient education, focusing on aspects of compet
Islet amyloid polypeptide (IAPP) is a beta cell hormone secreted together with insulin upon glucose stimulation. IAPP participates in normal glucose regulation, but IAPP is also known for its ability to misfold and form islet amyloid. Amyloid fibrils form through smaller cell toxic intermediates and deposited amyloid disrupts normal islet architecture. Even though IAPP and amyloid formation are mu
5-Acetyl-substituted pyrazole-3-carboxylic acid (H2L) forms [2 x 2] grid-like tetranuclear Cu(II) complexes with four five-coordinated copper(II) ions bridged by pyrazolate groups. Despite a significant dissociation of [Cu4L4(H2O)(4)]center dot 4H(2)O (1) in aqueous solution(1), it was possible to substitute the coordinated water molecules by pyridine ligands or azide anions. The resulting tetranu
