Near-Edge x‑ray absorption fine structure investigation of the quasi-One-Dimensional organic conductor (TMTSF)2PF6

We present high-resolution near-edge X-ray absorption fine structure (NEXAFS) measurements at the P L2/3 edges, F K edge, C K edge, and Se M2/3 edges of the quasi-one-dimensional (1D) conductor and superconductor (TMTSF)2PF6. NEXAFS allows probing the donor and acceptor moieties separately; spectra were recorded between room temperature (RT) and 30 K at normal incidence. Spectra taken around RT we

The Planners' Perspective on Train Timetable Errors in Sweden

Timetables are important for train punctuality. However, relatively little attention has been paid to the people who plan the timetables: the research has instead been more centred on how to improve timetables through simulation, optimisation, and data analysis techniques. In this study, we present an overview of the state of practice and the state of the art in timetable planning by studying the

Biomechanical exposure of industrial workers – Influence of automation process

Automated processes in industry have been implemented in order to get higher production rates, but our knowledge about their effects on physical exposure of the workers is still limited. Muscular load, postures, and movements of the head, neck/shoulders, upper arms, and wrists were recorded in 19 operators from two different car clutch disc production lines (manual and semi-automated). Higher angu

Enhanced broadband absorption in nanowire arrays with integrated Bragg reflectors

A near-unity unselective absorption spectrum is desirable for high-performance photovoltaics. Nanowire (NW) arrays are promising candidates for efficient solar cells due to nanophotonic absorption resonances in the solar spectrum. The absorption spectra, however, display undesired dips between the resonance peaks. To achieve improved unselective broadband absorption, we propose to enclose distribu

Assessing soil ecosystem processes – biodiversity relationships in a nature reserve in Central Europe

Background and aims: Plant diversity – ecosystem processes relationships are essential to our understanding of ecosystem functioning. We aimed at disentangling the nature of such relationships in a mesotrophic grassland that was highly heterogeneous with regards to nutrient availability. Methods: Rather than targeting primary productivity, like most existing reports do, we focused our study on bel

Health-Related Quality of Life After Surgery for Small Intestinal Neuroendocrine Tumours

Background: Overall survival for patients with small intestinal neuroendocrine tumours (siNETs) is long, even with metastatic disease, making quality of life issues relevant. The impact of surgery on quality of life is not known. We investigated determinants of health-related quality of life in patients who had undergone surgery for a siNET. Methods: Patients operated for a siNET between 1998 and

Behavioral spillovers from food-waste collection in Swedish municipalities

We estimate behavioral spillovers from environmental policy within the context of a natural experiment on food waste in Sweden. Exploiting the staggered implementation of food-waste collection across Swedish municipalities, we use a difference-in-difference design to measure the causal effect of introducing such collection on another pro-environmental behavior, namely the sorting of packaging wast

Direct electron transfer of dehydrogenases for development of 3rd generation biosensors and enzymatic fuel cells

Dehydrogenase based bioelectrocatalysis has been increasingly exploited in recent years in order to develop new bioelectrochemical devices, such as biosensors and biofuel cells, with improved performances. In some cases, dehydrogeases are able to directly exchange electrons with an appropriately designed electrode surface, without the need for an added redox mediator, allowing bioelectrocatalysis

Expression and prognostic significance of human epidermal growth factor receptors 1, 2 and 3 in oesophageal and gastric adenocarcinomas preneoadjuvant and postneoadjuvant treatment

AIMS: Neoadjuvant treatment has now become the standard of care for oesophageal and gastric cancer. The aim of this study was to investigate the influence of neoadjuvant therapy on the expression of human epidermal growth factor receptor 1 (HER1/EGFR), HER2 and HER3, in oesophageal and gastric adenocarcinoma.METHODS: Immunohistochemical expression of EGFR, HER2 and HER3 was examined and compared i

Integrin αVβ3 can substitute for collagen-binding β1-integrins in vivo to maintain a homeostatic interstitial fluid pressure

New Findings: What is the central question of this study? Collagen-binding β1-integrins function physiologically in cellular control of dermal interstitial fluid pressure (PIF) in vivo and thereby participate in control of extravascular fluid volume. During anaphylaxis, simulated by injection of compound 48/80, integrin αVβ3 takes over this physiological function. Here we addressed the question wh

Förnyelse - förbistring - försoning : En studie av vitaliseringsrörelser och ekumenisk utveckling på fem sydsvenska orter 1970–2015

Försoning är ett centralt tema i den kristna kyrkan. Denna studie indikerar en diskrepans mellan den teologiska förståelsen av försoning och den praxis som utövas under och efter en konflikt orsakad av olika uppfattningar om församlingens kultur eller identitet, särskilt i relation till vitaliseringsrörelser – förnyelse.I denna studie har etthundra konflikter eller potentiella konflikter som uppstReconciliation is a central theme in the Christian church. This study proceeds from a discrepancy between the theological understanding of reconciliation on the one hand and praxis in dealing with conflicts caused by different opinions about the culture or identity of the church on the other, especially in connection with vitalization (or renewal) movements.In this study, one hundred conflicts or

Case Studies as Narratives: Reflections Prompted by the Case of Victor, the Wild Child of Aveyron

Drawing on a celebrated case study of a feral child in France, the author argues that there are similarities between stories and case studies as types of narrative and that they are both capable of acting as insightful tools of management inquiry. Both case studies and stories call for narrative imagination to develop meaningful narratives. Serendipity, the accidental discovery of meaning or purpo

No special treatment of independent object motion for heading perception

How do we judge the direction of self-motion (i.e., heading) in the presence of independent object motion? Previous studies that examined this question confounded the effects of a moving object's speed and its position on heading judgments, and did not examine whether the visual system uses salient nonmotion visual cues (such as color contrast and binocular disparity) to segment a moving object fr

Global change-driven effects on dissolved organic matter composition : Implications for food webs of northern lakes

Northern ecosystems are experiencing some of the most dramatic impacts of global change on Earth. Rising temperatures, hydrological intensification, changes in atmospheric acid deposition and associated acidification recovery, and changes in vegetative cover are resulting in fundamental changes in terrestrial-aquatic biogeochemical linkages. The effects of global change are readily observed in alt

Smoking, body mass index, disease activity, and the risk of rapid radiographic progression in patients with early rheumatoid arthritis

BACKGROUND: Identification of risk factors for rapid joint destruction in early rheumatoid arthritis (RA) can be helpful for optimizing treatment, and improving our understanding of destructive arthritis and its mechanisms. The objective of this study was to investigate the relationship between early RA patient characteristics and subsequent rapid radiographic progression (RRP).METHODS: An incepti

The opportunity prior : A simple and practical solution to the prior probability problem for legal cases

One of the greatest impediments to the use of probabilistic reasoning in legal arguments is the difficulty in agreeing on an appropriate prior probability for the ultimate hypothesis, (in criminal cases this is normally “Defendant is guilty of the crime for which he/she is accused”). Even strong supporters of a Bayesian approach prefer to ignore priors and focus instead on considering only the lik

Data consistency of the burning velocity measurements using the heat flux method : Hydrogen flames

Consistent datasets of experiments are highly important both for validation and optimization of kinetic mechanisms. An analysis of the data consistency of all available burning velocity measurements of hydrogen flames using the heat flux method at atmospheric pressure is performed in the present work. A comparison of many experiments performed in several laboratories with different types of diluti

Biomarkers for equine joint injury and osteoarthritis

We report the results of a symposium aimed at identifying validated biomarkers that can be used to complement clinical observations for diagnosis and prognosis of joint injury leading to equine osteoarthritis (OA). Biomarkers might also predict pre-fracture change that could lead to catastrophic bone failure in equine athletes. The workshop was attended by leading scientists in the fields of equin

Monitoring biofilm function in new and matured full-scale slow sand filters using flow cytometric histogram image comparison (CHIC)

While slow sand filters (SSFs) have produced drinking water for more than a hundred years, understanding of their associated microbial communities is limited. In this study, bacteria in influent and effluent water from full-scale SSFs were explored using flow cytometry (FCM) with cytometric histogram image comparison (CHIC) analysis; and routine microbial counts for heterotrophs, total coliforms a
