Hemicelluloses with high molecular mass are needed for the manufacture of value added products such as food packaging barrier films. In this work such molecules were recovered from chemithermomechanical pulp (CTMP) process water using an innovative three-stage process comprising membrane separation and enzymatic treatment with laccase. Microfiltration followed by ultrafiltration was found to be a

The medium-induced one-gluon radiation spectrum off a massive quark-antiquark (q (q) over bar) antenna traversing a colored QCD medium is calculated in this contribution. The gluon spectrum off the antenna computed at first order in the opacity expansion is collinear finite but infrared divergent, which is different from the result obtained from an independent emitter which is both infrared and co

Energy productivity is crucial for sustainable development.We use cointegration analyses to investigate the effect of electricity on energy productivity in Swedish industry from 1930 to 1990. Electricity augmented energy productivity in those industrial branches that used electricity formultiple purposes. This productivity effect goes beyond “book-keeping effects,” i. e. it is not only the result

We present transport measurements in superconductor-nanowire devices with a gated constriction forming a quantum point contact. Zero-bias features in tunneling spectroscopy appear at finite magnetic fields and oscillate in amplitude and split away from zero bias as a function of magnetic field and gate voltage. A crossover in magnetoconductance is observed: Magnetic fields above similar to 0.5 T e

Covalently anchored Ni(II)-C-protected amino acid (L-histidine, L-cysteine, and L-cystine) complexes inspired by the active site of the Ni-superoxide dismutase enzyme were synthesised using chloropropylated silica gel as support. The structural features of the surface complexes were studied by the Kjeldahl method and ICP-MS, mid/far IR, UV-vis diffuse reflectance, and X-ray absorption spectroscopi

Background: To ensure a correct interpretation of results obtained with quantitative real-time reverse transcription-polymerase chain reaction (RT-qPCR), it is critical to normalize to a reference gene with stable mRNA expression in the tissue of interest. GADPH is widely used as a reference gene in ovarian tumour studies, although lacking tissue-specific stability. The aim of this study was to id

Statsvetenskapliga förbundet fyller 40 år och det uppmärksammas med en skrift där svenska och nordiska samhällsforskare i ett drygt fyrtiotal uppsatser redovisar sin syn på svensk statsvetenskap. Några gör det genom personliga bildningsresor, andra försöker fånga de långa linjerna i en specialitets utveckling eller tar spjärn mot etablerade traditioner. Några skribenter argumenterar för nya empiri

Estimating temporal trends in spatially structured populations has a critical role to play in understanding regional changes in biological populations and developing management strategies. Designing effective monitoring programmes to estimate these trends requires important decisions to be made about how to allocate sampling effort among spatial replicates (i.e. number of sites) and temporal repli

IEEE 1687 (IJTAG) has been developed to enable flexible and automated access to the increasing number of embedded instruments in today's integrated circuits. These instruments enable efficient post-silicon validation, debugging, wafer sort, package test, burn-in, bring-up and manufacturing test of printed circuit board assemblies, power-on self-test, and in-field test. Current paper presents an ov

A structural characterization of mixed micelles formed in aqueous solution by the PEO-PPO-PEO triblock copolymer P123 and the nonionic surfactant C(12)EO(6) was carried out using various techniques, including ultralow shear viscosimetry, depolarized dynamic light scattering (VH-DLS), depolarized static light scattering (VH-SLS), and small-angle X-ray scattering (SAXS). The sphere-to-rod transition

An amyloid form of the protein α-synuclein is the major component of the intraneuronal inclusions called Lewy bodies, which are the neuropathological hallmark of Parkinson's disease (PD). α-Synuclein is known to associate with anionic lipid membranes, and interactions between aggregating α-synuclein and cellular membranes are thought to be important for PD pathology. We have studied the molecular

Abstract General practice is a broad and multifaceted field of knowledge. Political steering instruments declare that general practice and primary care are characterized by a holistic perspective on the individual, with quality, accessibility, continuity, and cooperation being important factors. For the last few decades, quality assurance has been in focus in Swedish health care. Inspiration has c

In this work, a coordinate solver for elastic net regularized logistic regression is proposed. In particular, a method based on majorization maximization using a cubic function is derived. This to reliably and accurately optimize the objective function at each step without resorting to line search. Experiments show that the proposed solver is comparable to, or improves, state-of-the-art solvers. T

Popular Abstract in Swedish Kisel (Si) förekommer i alla naturliga vatten i form av löst kisel och är ett näringsämne för många växt- och djurarter. Löst kisel kommer ursprungligen från kiselhaltiga mineral som har vittrat. Vid vittringen går det åt koldioxid (CO2) och på så vis finns det ett samband mellan omsättningen av kisel och kol. Både upptag och vittring av kisel bidrar till att fördelningSilicon (Si) is ubiqutious in natural waters as dissolved silica (DSi) and is used as a nutrient by many plant and animal species. DSi ultimately derives from the weathering of silicate minerals, a process which also consumes atmospheric CO2 and couples the silicon and carbon cycles. These processes, among others, impart observable fractionations to the stable isotopes of silicon, which makes the

Background: The neural transcription factor SOX11 has been described as a prognostic marker in epithelial ovarian cancers (EOC), however its role in individual histological subtypes and tumour grade requires further clarification. Furthermore, methylation-dependent silencing of SOX11 has been reported for B cell lymphomas and indicates that epigenetic drugs may be used to re-express this tumour su

Cancer-associated fibroblasts (CAF) stimulate tumor growth and metastasis. Signals supporting CAF function are thus emerging as candidate therapeutic targets in the tumor microenvironment. The chemokine CXCL14 is a potent inducer of CAF protumorigenic functions. This study is aimed at learning how the protumoral functions of CXCL14-expressing CAF are maintained. We found that the nitric oxide synt
