It is well recognized that the capacity of soils to sequester carbon (C) is strongly influenced by nitrogen (N) and phosphorus (P) availability because of the strong stoichiometric links between these biogeochemical cycles. Human disturbance (e.g., deposition, fertilization, and mining), has, and continue to have, caused large imbalances between the biogeochemical cycles and changing nutrient avai
To keep global warming within 1.5 °C of pre-industrial levels, there needs to be a substantial decline in the use of coal power by 20301,2 and in most scenarios, complete cessation by 2050. The members of the Powering Past Coal Alliance (PPCA), launched in 2017 at the UNFCCC Conference of the Parties, are committed to “phasing out existing unabated coal power generation and a moratorium on new coa
PURPOSE: NODDI (Neurite Orientation Dispersion and Density Imaging) and DTI (Diffusion tensor imaging) may be useful in identifying abnormal regions in patients with MRI-negative refractory epilepsy. The aim of this study was to determine whether NODDI and DTI maps including neurite density (ND), orientation dispersion index (ODI), mean diffusivity (MD) and fractional anisotropy (FA) can detect st
Europe is in the midst of a generational transformation that is as much rooted in a complex constellation of socio-economic crises, as it is the product of an ideological revolution, championed by the far-right, in which the Western Balkans, in particular, have become a veritable totem for real and imagined problems confronting the EU and “the West” more broadly.
The micro-mechanisms of fracture in a laminate composed of an aluminium foil and a polyethene film are considered. The laminate as well as the freestanding layers were fracture mechanically tested. Inspection of the broken cross-sections shows that fracture occurs through necking, i.e., localised plastic deformation leading to a decreasing and eventually vanishing cross-section. This occurs ahead The micro-mechanisms of fracture in a laminate composed of an aluminium foil and a polyethene film are considered.

Background: There is paucity of data regarding the significance of high percentage of premature ventricular contractions (PVCs) in healthy children and their impact on left ventricular (LV) function and the risk of ventricular arrhythmias. The purpose of this study was to assess the prevalence of LV systolic dysfunction in children with frequent PVCs and determine whether PVC characteristics were
For patients living with chronic conditions, the daily life will change due to symptoms, drug treatment, and psychosocial factors caused by the disease. Our studies show that Swedish patients with PAH or CTEPH are satisfied with the information they have received, but still have a wish for more. Therefore, it is important to repeat the information on a regular basis and to make sure that patients
The number of the X chromosome–linked genes has been previously suggested to influence immune responses and the development of autoimmune diseases. In the present study, we aimed at evaluating the level of expression of CD40L (an X-linked gene involved in adaptive immunity) and TLR7 (an X-linked gene involved in innate immunity) in a variety of different karyotypes. Those included males, females a
Multiple reactions on patch testing can be related to contact allergy to components of the patch test system used, for example, contact allergy to aluminium.1-11 We report on two cases with contact allergy to Finn Chamber AQUA (FCA) test chambers (SmartPractice, Phoenix, Arizona).
Background: Allergic contact dermatitis caused by henna-based hair-colouring products has been associated with adulteration of henna with p-phenylenediamine (PPD). Objectives: To develop a testing approach based on in vitro techniques that address key events within the skin sensitization adverse outcome pathway in order to evaluate the allergenic potential of hair-colouring products. Methods: The
The transport characteristics of a disordered, multilayered MoS2 nanoflake in the insulator regime are studied by electrical and magnetotransport measurements. The MoS2 nanoflake is exfoliated from a bulk MoS2 crystal and the conductance G and magnetoresistance are measured in a four-probe setup over a wide range of temperatures. At high temperatures, we observe that lnG exhibits a -T-1 temperatur
Direct numerical simulations (DNS) of statistically planar flames at moderate and high Karlovitz number (Ka) have been used to perform an a priori evaluation of a presumed-PDF model approach for filtered reaction rate in the framework of large eddy simulation (LES) for different LES filter sizes. The model is statistical and uses a presumed shape, based here on a beta-distribution, for the sub-gri
In boreal forest soils, mycelium of mycorrhizal fungi is pivotal for regulating soil carbon (C) cycling and storage. The carbon use efficiency (CUE), a key parameter in C cycling models, can inform on the partitioning of C between microbial biomass, and potential soil storage, and respiration. Here, we test the dependency of mycorrhizal mycelial CUE on stand age and seasonality in managed boreal f
Background: Adults with complex congenital heart disease (CHD) have reduced aerobic capacity and impaired muscle function. We therefore hypothesized that patients have a lower skeletal muscle mass and higher fat mass than controls. Methods: Body composition was examined with full body Dual-Energy x-ray Absorptiometry (DXA) in 73 patients with complex CHD (mean age 35.8 ± 14.3, women n = 22) and 73
