Measurements and Monte-Carlo simulations of the particle self-shielding effect of B4C grains in neutron shielding concrete
A combined measurement and Monte-Carlo simulation study was carried out in order to characterize the particle self-shielding effect of B4C grains in neutron shielding concrete. Several batches of a specialized neutron shielding concrete, with varying B4C grain sizes, were exposed to a 2 Å neutron beam at the R2D2 test beamline at the Institute for Energy Technology located in Kjeller, Norway. The
Mechanism of chromium poisoning the conventional cathode material for solid oxide fuel cells
Chromium poisoning the La0.875Sr0.125MnO3 (LSM) cathode for solid oxide fuel cells is a critical issue that can strongly affect the stability. In this study, we evaluate the temperature distribution in a SOFC based on a 3D model and then combine conductivity test and material computation to reveal the effects of chromium in SUS430 stainless steels on LSM conductivities. The starch concentration in
Life histories of microalgal species causing harmful blooms : Haploids, diploids and the relevance of benthic stages
In coastal and offshore waters, Harmful Algal Blooms (HABs) currently threaten the well-being of coastal countries. These events, which can be localized or involve wide-ranging areas, pose risks to human health, marine ecosystems, and economic resources, such as tourism, fisheries, and aquaculture. Dynamics of HABs vary from one site to another, depending on the hydrographic and ecological conditi
Birimian crustal growth in the West African Craton : U-Pb, O and Lu-Hf isotope constraints from detrital zircon in major rivers
Combined U-Pb, O and Lu-Hf isotope analyses of detrital zircon grains from five major rivers in Ghana are used to investigate the growth and evolution of the Birimian terrane of the West African Craton. The majority of the analysed zircon yields supra-chondritic εHf values, suggesting derivation from primarily juvenile host magmas. Zircon grains from the Birim River in southwestern Ghana deviate f
Endoscopic versus Laparoscopic Full-Thickness Biopsy in the Pathological Evaluation of the Enteric Nervous System
A full-thickness biopsy of the bowel wall is required to evaluate the enteric nervous system. A patient with aggravating gastrointestinal symptoms underwent a laparoscopic full-thickness biopsy of the ileum and, 1 year later, an endoscopic full-thickness biopsy of the sigmoid colon. Both samples showed enteric neuropathy characterized by vacuolated and enlarged neurons. The length of the myenteric

Cone-beam computed tomography, a new low-dose three-dimensional imaging technique for assessment of bone erosions in rheumatoid arthritis : reliability assessment and comparison with conventional radiography – a BARFOT study
Objectives: To determine the intra- and inter-observer agreement of erosions detected and scored with cone-beam computed tomography (CBCT) of bones in the hands and feet, and to compare CBCT with conventional radiography (CR) for assessment of bone erosions in patients with long-standing rheumatoid arthritis (RA). Method: Thirty patients with long-standing RA from the Better Anti-Rheumatic Pharmac
De-pathologizing Perversion : Proust’s Sexual Discourses and Their Chinese Translations
The sexological aspects of Proust’s work have largely been neglected in its Chinese reception. The paper focuses on the Chinese (re)translations of Proust’s sexual discourses in À la recherche du temps perdu and expounds the epistemic challenges and the evolving strategies of translating sadomasochism and homosexuality into Chinese. It further explores how these observations refract the changing a

Evolution : An Irresistibly Clear View of Land
Visually guided predation is range-limited in water, but works over long distances on land. This may have driven our last aquatic ancestors to evolve large eyes on the top of their head for spotting crunchy meals on ancient riverbanks.
Precision medicine in obesity and type 2 diabetes : The relevance of early-life exposures
BACKGROUND: Type 2 diabetes is highly prevalent and devastating. Obesity is a diabetogenic factor, driving insulin resistance and a compensatory demand for increased insulin secretion from the pancreatic cells; a failure to address this demand results in diabetes. Accordingly, primary and secondary prevention of obesity are at the core of diabetes prevention programs. The development of obesity an

Automated computer-assisted quantitative analysis of intact murine lungs at the alveolar scale
Using state-of-the-art X-ray tomographic microscopy we can image lung tissue in three dimensions in intact animals down to a micrometer precision. The structural complexity and hierarchical branching scheme of the lung at this level of details, however, renders the extraction of biologically relevant quantities particularly challenging. We have developed a methodology for a detailed description of
C-H Activation Reactions Mediated by Pd Based Heterogeneous Catalysts : Regioselective Formation of C-O and C-X Bonds
Katalys är ryggraden i många processer i vardagen. Även människokroppen styrs huvudsakligen av katalysatorer. Detta viktiga koncept tillåter oss att på ett miljövänligt sätt konvertera råmaterial som råolja och naturgas till värdefulla och oersättliga produkter, till exempel motorbränslen, läkemedel och agrokemikalier. En katalysprocess drivs av en katalysator, vilket således är en substans som, uNew classes of N-heterocyclic carbene-palladium(II) complexes containing either a vinyl group in different positions or an anthracene tag in the backbone of the N-heterocycle were synthesized and fully characterized. The vinyl based complexes were copolymerized with divinylbenzene to fabricate robust polymer-supported NHC-Pd(II) systems, while the anthracene based complexes were π-stacked onto the
Helping Hand grasp rehabilitation : Preliminary assessment on chronic stroke patients
The Helping Hand (HH) system is a novel grasp rehabilitation platform aimed at simplifying the clinical usage of wearable electrode arrays for neuromuscular electrical stimulation (NMES). In a randomized dose-matched, clinical study we evaluate usability and effectiveness of the HH treatment, and of other enriched upper limb rehabilitation treatments, and compare the outcomes. This paper shows the

Experiences of living with increased risk of developing colorectal and gynaecological cancer in individuals with no identified gene mutation
Background: In most families with familial cancers, mutations have not been demonstrated; thus, healthy individuals cannot be tested for mutation status. As a consequence, many persons at risk of familial cancer live with an unknown, but presumably high, risk of developing cancer. Aim: The aim of this study was to describe individuals' perceptions of living with an increased risk of colorectal and
