Provenance of Cretaceous and Paleocene sandstones in the West Greenland basins based no detrital zircon dating

The extensive and very deep ?Jurassic/Cretaceous–Palaeogene sedimentary basins offshore West Greenland have a significant petroleum exploration potential. This is particularly true for the offshore region west of Disko and Nuussuaq where a live petroleum system has been documented for many years. At present, stratigraphic knowledge in this area is almost nonexistent and analogue studies from onsho

A well-preserved bimodal Archaean volcanic succession in the Tasiusarsuaq terrane, South-West Greenland

During the field campaign in the Nuuk region, one of the objectives was to describe Archaean primary geological environments (Hollis et al. 2006). On Nunatak 1390, which is part of the Tasiusarsuaq terrane (Figs 1, 2), a bimodal volcanic succession is preserved and interpreted as former ocean floor. The field investigation included geological mapping and sampling of the volcanic sequence comprisin

Geological observations in the southern West Greenland basement from Ameralik to Frederikshåb lsblink in 2008

In 2008, the Geological Survey of Denmark and Greenland began a project in collaboration with the Bureau of Minerals and Petroleum of Greenland with the aim to publish a web-based, seamless digital map of the Precambrian bedrock between 61°30´ and 64°N in southern West Greenland. Such a map will be helpful for the mineral exploration industry and for basic research. Producing an updated digital ma

The 7Be(d, α)5Li(p α) and 7Be(d, p)8Be*(p 7Li) reactions at 5 MeV/u

The 7Be(d, α)5Li and 7Be(d, p)8Be*(p 7Li) reactions are studied at 5 MeV/u in the context of the cosmological lithium problem. This work aims to probe the contribution of 7Be destruction mechanisms, particularly through channels that populate intermediate unbound states of 5Li and 8Be. The contribution of 7Be(d, α)5Li(p α) reaction is separated from the 7Be(d, p)8Be*(2α) reaction. The 7Be(d, p)8Be

Ion probe dating of a migmatite in SW Sweden : The fate of zircon in crustal processes

A migmatitic orthogneiss in the Western Segment in the Sveconorwegian Province of the Baltic Shield was dated using the ion-probe U-Pb method on zircon grains, which were also analysed for rare earth elements. Mesosome zircons have 1.605±0.010Ga magmatic cores, which places the gneiss protolith in the same 1.61-1.59Ga time bracket as continental arc-related gneisses, abundant in this part of the S

Subgrain-scale decoupling of Re and 187Os and assessment of laser ablation ICP-MS spot dating in molybdenite

Reproducibility of Re-Os molybdenite ages depends on sample size and homogeneity, suggesting that Re and Os are decoupled within individual molybdenite crystals and do not remain spatially linked over time. In order to investigate the Re-Os systematics of molybdenite at the subgrain (micron) scale, we report LA-ICP-MS Re-Os ages for an Archean molybdenite crystal from Aittojärvi, Finland, analyzed

187RE-187OS evidence for crustal lenses of Svecofennian age within the Mylonite Zone, SW sweden

Re and Os concentrations and isotopic composition were analysed in four ultramafic cumulates from the Kedum tectonic lens within the Mylonite Zone, SW Sweden. An 1887±36 Ma isochron is obtained for six samples and interpreted to date the Kedum body. This is significantly older than the -1600-1700 Ma surrounding crust and the first rocks of Svecofennian age west of the Trans Scandinavian Igneous Be

Feasibility study of the internet-based intervention “Strategies for Empowering activities in Everyday life” (SEE 2.0) for use by people with chronic diseases and long-term disorders in healthcare: A study protocol.

Introduction: Proactive and easily accessible interventions are needed to support people with long-term health conditions who experience limitations in activities of everyday life. However, there is a lack of interventions that promote self-management skills that prevent deterioration and improve health. The internet-based programme 'Strategies for Empowering Activities in Everyday Life' (SEE) sup

Sensory pollutants have negative but different effects on nestbox occupancy and breeding performance of a nocturnal raptor across Europe

Anthropogenic noise and artificial light at night (ALAN) are expanding globally, acting as pervasive sensory pollutants that can disrupt wildlife behaviour and reproduction. While most research has focused on diurnal species, the effects of these pollutants on the ecological response of nocturnal predators remain poorly understood. Using data from nine European countries, we investigated the effec

The relationship between experienced losses and damages, risk tolerance and livelihood thresholds in the East Gippsland, Australia, farming sector

Losses and damages are residual impacts of climate change that occur despite mitigation and adaptation actions. Losses and damages are borderless, albeit experienced differently between and within countries. Although Australia is a high-income country, recent losses and damages have been particularly severe. Over the last eight years, farmers in East Gippsland, Victoria, have been severely affecte

The remarkable Re-Os chronometer in molybdenite : How and why it works

The Re-Os (rhenium-osmium) chronometer applied to molybdenite (MoS2) is now demonstrated to be remarkably robust, surviving intense deformation and high-grade thermal metamorphism. Successful dating of molybdenite is dependent on proper preparation of the mineral separate and analysis of a critical quantity of molybdenite, unique to each sample, such that recognized spatial decoupling of 187Re par

Dating mafic-ultramafic intrusions by ion-microprobing contact-melt zircon : Examples from SW Sweden

Zircons from anatectic melts of the country rocks of three Proterozoic mafic-ultramafic intrusions from the Sveconorwegian Province in SW Sweden were microanalyzed for U-Th-Pb and rare earth elements. Melting and interaction of the wall rocks with the intrusions gave rise to new magmas that crystallized zircon as new grains and overgrowths on xenocrysts. The ages of the intrusions can be determine

Prognostic Value of Right Ventricular Global Wasted Work in Precapillary Pulmonary Hypertension : A 3D Echocardiographic Study

AIM: Right ventricular (RV) function determines symptom burden and clinical outcomes in pulmonary hypertension (PH). Global wasted work (GWW) quantifies mechanical inefficiencies in RV performance associated with elevated afterload, but is inadequately characterized in precapillary PH. We assessed the association of GWW with echocardiographic indices of RV remodeling, RV-PA coupling and invasive h

A Handwritten Text Recognition Dataset for Ajami Manuscripts in Fulfulde and Hausa

We present the first ever dataset of manually segmented and transcribed Ajami manuscripts written in Fulfulde and Hausa. The term Ajami refers to modified Arabic-script orthographies in Africa. Existing handwritten text recognition (HTR) and optical character recognition (OCR) models for Arabic-script languages perform poorly on West African manuscripts due to a lack of these manuscripts represent

Microplastics in the Southern Brazilian estuary : Interactions between environment, morphology, and seasonal variation

Estuaries are complex environments rich in biodiversity, making it challenging to understand the distribution and occurrence of microplastics due to the multiple variables that can influence the movement of these particles. Based on this, this study evaluated the influence of different environmental aspects on the distribution and transport of microplastics in the surface waters of the Tramandaí R

Understanding drought related tree responses using deep learning approaches and satellite based proxy

Recent droughts from 2017 to 2020 induced significant stress on woodland canopies across eastern Australia, resulting in widespread tree browning and mortality. However, the trajectory of post-drought recovery remains unclear, with uncertainty about whether canopy conditions are improving or continuing to decline. Identifying the key local environmental and climatic factors influencing drought-ind

Leveraging Intra-Organizational Networks for Environmental Management Case Study-Based Potentials, Challenges, and Success Factors

The aim of this study was to investigate whether cross-site networking of environmental managers in globally active companies can offer a solution for the efficient internal use of intangible resources. In addition, it examines whether findings from research and practice on interorganisational environmental networks can be transferred to intraorganisational contexts. The study is based on a case s

Prolonged excessive weight induces spontaneous meniscal degeneration in sows : A preclinical model for obesity-related knee OA

Knee osteoarthritis (OA) and obesity are closely linked, with obesity being the primary risk factor for OA. This study used the medial meniscus of sows (250 kg, 4–6 years old) as a model for spontaneous OA, comparing them to lighter pigs (110 kg, 7–8 months old). The joints were collected according to the 3Rs principles (Replacement, Reduction and Refinement) and compared using macroscopic and mic

PARKIN protein-deficient iPSC line (FINi006-A) from an early-onset Parkinson's disease female patient

Compound heterozygosity for strong hypomorphic mutations in the PRKN gene is a common cause of autosomal familial Parkinson's disease (PD). We generated an iPSC cell line from the fibroblasts of a PARKIN protein-deficient early-onset PD female patient, carrying genomic deletions of exon 2 and exons 5–7. This line displays characteristic human iPSC morphology and expression of pluripotency-associat
