The aim of the European Funded Project BRAFO (benefit-risk analysis of foods) project was to develop a framework that allows quantitative comparison of human health risks and benefits of foods based on a common scale of measurement. This publication describes the application of the BRAFO methodology to three different case studies: the formation of acrylamide in potato and cereal based products, t

The low field ESR lineshape and the electron spin-lattice relaxation correlation function are calculated using the stochastic Liouville theory for an effective electron spin quantum number S = 1. When an axially symmetric permanent zero field splitting provides the dominant relaxation mechanism, and when it is much larger than the rotational diffusion constant, it is shown that both electron spin

We present a protocol for a facile orientation specific deposition of plate-like mesoporous SBA-15 silica particles onto a surface (mesopores oriented normal to surface). A drop of an aqueous dispersion of particles is placed on the surface and water vaporizes under controlled relative humidity. Three requirements are essential for uniform coverage: particle dispersion should not contain aggregate

Popular Abstract in Swedish Frontotemporal demens (FTD) är en grupp av demenssjukdomar som främst drabbar hjärnans pannlober och främre tinninglober. Gemensamt för FTD-sjukdomarna är en fortskridande nervcellsförlust och förtvining av framför allt hjärnbarken. Sjukdomen medför personlighetsförändring med beteendestörningar, förändringar i känsloliv och kognitiva svårigheter. En försämring av språkFrontotemporal dementia (FTD) is the clinical term for a heterogeneous group of dementia disorders with symptoms emerging from frontotemporal lobar degeneration (FTLD). FTD encompasses the behavioural variant (bvFTD) and the progressive aphasias: progressive non-fluent aphasia (PNFA) and semantic dementia (SD). Neuropathological classification is based on protein pathology with three major subgrou

The purpose of this study was to evaluate the longitudinal trajectories of acute stress reactions over the course of diagnosis, treatment, and follow-up assessments in a group of non-metastatic breast cancer patients during five different moments of the illness process, and to identify psychological predictors of the trajectories.

Although the phenomenon of resistance to change has gained considerable attention in organization theory over the years, the meaning of the concept is rarely discussed. In this paper, a conceptual framework is suggested that distinguishes between four interpretations of resistance and builds upon the two variables of changeability and emotionality. Each interpretation is based on various assumptio

Background: Degraded extracellular matrix can stimulate the innate immune system via the Toll-Like Receptor-4 (TLR4). In the pancreas, syndecan-anchored heparan sulphate (HS) on the ductal epithelium can be cleaved off its protein cores by the proteases (trypsin and elastase) and potentially activate TLR4 signalling. Methods: To investigate this signalling event, a low sulphated HS (500 mu g/ml) w

Zinc oxide nanorod-extended gate field effect transistor (MOSFET) is demonstrated for the detection of calcium (Ca2+) ions. ZnO nanorods were grown on the surface of a silver wire to produce an electrochemical nanosensor for selectively detecting Ca2+. The electrochemical response from the interaction between the ZnO nanorods and Ca2+ in an aqueous solution is coupled directly to the gate of a fie

This study investigates the effects that public sector reforms had in the cultural field in European countries over the past two decades. The study highlights changing conditions for public/nonprofit management due to governance and public sector reforms. It does so by applying a multidisciplinary literature survey methodology, which is rare in management studies. The literature survey identifies

This paper combines an atmospheric transport model and a terrestrial ecosystem model to estimate gross primary productivity (GPP) and net ecosystem productivity (NEP) of the land biosphere. Using atmospheric CO2 observations in a Carbon Cycle Data Assimilation System (CCDAS) we estimate a terrestrial global GPP of 146 +/- 19 GtC/yr. However, the current observing network cannot distinguish this be

Brachyradia, new genus, is proposed and described for two new species of the tribe Exechiini (Diptera: Mycetophilidae) from the Oriental and Australasian regions. The type species, Brachyradia asianca, new species, is described from Thailand, Malaysia, and Indonesia (Sulawesi), and a second species, Brachyradia australis, new species, from Indonesia (Sulawesi) and Papua New Guinea. The systematic

The enzyme myeloperoxidase shows several unusual properties compared to other peroxidases, e.g. a red-shifted absorption spectrum and a peroxidase activity towards chloride. It has been suggested that this is caused by the unusual covalent links between the heme group and the surrounding protein, but whether it is caused by the two ester links to Glu-242 and Asp-94 or the sulfonium ion linkage to

The aim of this was to determine whether the change of size observed at the first response evaluation after initiation of first-line combination chemotherapy correlates with overall survival (OS) in patients with metastatic breast cancer (MBC). The change in size of tumors derived from measurements according to Response Evaluation Criteria In Solid Tumors (RECIST) at the first evaluation on comput

This paper analyses global climate politics from the 2007 Bali Roadmap over the 2009 breakdown at COP15 to the following COP meetings with a focus on central issues and tendencies. The analysis is structured by applying the concepts of content and process as empirical and heuristic tools. This is used as the point of departure to analyse the road to Paris, where COP21 is held in 2015 with the stat

This paper examines the importance of influent fractionation, kinetic, stoichiometric and mass transfer parameter uncertainties when modeling biogas production in wastewater treatment plants. The anaerobic digestion model no. 1 implemented in the plant-wide context provided by the benchmark simulation model no. 2 is used to quantify the generation of CH4, H-2 and CO2. A comprehensive global sensit

Adaptive radiations have long served as living libraries to study the build-up of species richness; however, they do not provide good models for radiations that exhibit negligible adaptive disparity. Here, we review work on damselflies to argue that nonadaptive mechanisms were predominant in the radiation of this group and have driven species divergence through sexual selection arising from male-f
