Dissolved organic carbon (DOC) affects the acidity in soil and lake waters and buffers both against acidification and against recovery from acidification. Current acidification assessments, based on the widely used MAGIC (Model of Acidification of Groundwater In Catchments) model, often assume constant DOC concentrations through time, but observations suggest this assumption may not be warranted.

Objective. To investigate the course of disability related to the upper extremities (UEs) in early rheumatoid arthritis (RA), and to assess correlations between such disability and clinical variables, including grip force. Methods. In an inception cohort of patients with early RA (diagnosed 1995-2005, N = 222, follow-up 10 yrs), disability of the UEs was assessed using a subscore of the Health Ass

Acute SARS-CoV-2 infections are not always diagnosed; hence an unknown proportion of all infections are not documented. SARS-CoV-2 can induce spike and nucleocapsid protein specific IgG antibodies, which can be detected in seroprevalence studies to identify a previous infection. However, with the introduction of vaccines containing the spike protein it is no longer possible to use spike-IgG as a m

Organ-on-a-chip devices are predominately made of the polymer polymethylsiloxane (PDMS), exhibiting several attractive properties e.g., transparency, gas permeability, and biocompatibility. However, the attachment of cells to this polymer has proven challenging, especially for delicate primary cells e.g., small intestinal organoid-derived epithelial cells. Hence, a need to functionalize and coat t

Impossible colors is not a hypothesis, but rather more hyperbole. In this musical piece "impossible colors" refer to illusions of timbre in sound, not vision.Impossible colors are colors that we do not normally see; that some fictional colors are beyond the functional perceptual space of humans. Some theories looking at forbidden colors, borrowed from color research in vision are applied in this p

To Alan Walmsley, at sixty-fiveJarash (also Jerash, Greek Gerasa) ranks among the principal urban centres of Late Antique and Early Islamic Jordan. Despite being one of the most intensively investigated urban sites within the region, the history of Jarash during the Islamic ages, in particular after the massive earthquake of 749, remains a topic of profound disagreement. Drawing on previously unpu

Objectives: North Sea–Progressive Myoclonus Epilepsy (NS-PME) is a rare, childhood-onset disorder primarily characterized by movement disorders including progressive myoclonus and ataxia; subsequently accompanied by varying degrees of epilepsy. While motor symptoms are clearly defined, quality of life (QoL) has never been investigated in NS-PME. Additionally, nonmotor symptoms (NMS) including anxi

There is a need for ground-breaking technologies to boost crop yield, both grains and biomass, and their processing into economically competitive materials. Novel cereals with enhanced photosynthesis and assimilation of greenhouse gasses, such as carbon dioxide and ozone, and tailored straw suitable for industrial manufacturing, open a new perspective for the circular economy. Here we describe the

Chapter 7, written by Vera Sadovska, Oksana Mont and Yuliya Voytenko Palgan, explores the economic sustainability of food-sharing initiatives (FSIs). Bringing together insights from a systematic literature review and empirical research in Barcelona, the chapter examines the economic challenges FSIs face, such as managing operational costs, obtaining funding and dealing with regulatory complexities

Denna artikel behandlar fyndet av en kota från en bardval som påträffades under utgrävningarna av Västra Karaby, en vendeltida boplats i västra Skåne. Fynd av bardvalar i skånska järnåldersboplatser är mycket sällsynta. I artikeln diskuteras kotans proveniens, kronologiska tillhörighet och betydelse för förståelsen av boplatsen. En taxonomisk bestämning av kotan har gjorts genom den benkemiska pep

Inventering av djurbensmaterialet från grävningarna i Västra Karaby 1969-1971. Även information om grävningen 1968. Innehåller anläggningslistor (med anläggningar innehållandes ben) samt översiktsplan med anläggningsnummer.

Contemporary research observes how foreign information influence present a governing challenge for liberal democratic states. Less attention has been paid to how this governing dilemma emerged in its present form. This article outlines a genealogy of the longstanding Swedish strategy of psychological defence with the aim of tracing historical trajectories of liberal democratic thinking about infor

The ever-growing reliance on electronic devices and the burgeoning field of green energy necessitate efficient and different gain AC-DC converters for a myriad of applications, from electric drives to solar cells and grid-connected inverters. This paper introduces a hybrid closed-loop bridged and bridgeless Single-Ended Primary-Inductor Converter (SEPIC) topologies featuring switched-capacitor net

The present thesis investigates the material scale of six political economiesdistributed across the dry-farming plains and piedmonts of the Middle Bronze AgeJazīrah and the Bilād al-Šām. This is done using a comparative and interdisciplinaryapproach combining the large-scale analysis of administrative cuneiform texts withthe compilation of relevant archaeological survey datasets. Drawing on theori

The silicon isotope composition (δ30Si) of biogenic silica is often used as an archive of past environmental conditions. For example, sponge spicule δ30Si is known to be related to seawater-dissolved Si concentrations. Such a proxy application requires that the δ30Si is not diagenetically altered—or at least that any alteration can be identified and accounted for. Yet the preservation of pristine

Objective To assess patient's self-reported global assessment of health (PGA) in relation to inflammation, pain and disability in patients with rheumatoid arthritis (RA). Methods Data were obtained from the Better Anti-Rheumatic PharmacOTherapy early RA cohort, in which patients were scheduled for follow-up of 15 years. Longitudinal PGA trajectories were identified using hierarchical agglomerative

The precuneus is a site of early amyloid-beta (Aβ) accumulation. Previous cross-sectional studies reported increased precuneus fMRI activity in older adults with mild cognitive deficits or elevated Aβ. However, longitudinal studies in early Alzheimer’s disease (AD) are lacking and the relationship to the Apolipoprotein-E (APOE) genotype is unclear. Investigating the PREVENT-AD dataset, we assessed
