Organic contaminants (polycyclic aromatic hydrocarbons (PAHs), polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), and chlorinated paraffins (CPs)) and heavy metals and metalloids (Ag, Cd, Co, Cr, Cu, Hg, Ni, Pb, Sb, Zn) were analysed in surface soil samples from the Agbogbloshie e-waste processing and dumping site in Accra (Ghana). In order to identify which of the pollutants ...

<i>Background</i> - Anxious and depressive symptoms in youth are highly prevalent, are often comorbid and have a high rate of relapse. Preventive interventions are promising, but follow-up results are lacking. The transdiagnostic EMOTION program is an indicated preventive cognitive behavioral therapy (CBT) intervention targeting children aged 8–12 years.<p> <p><i>Methods</i> - The present study ...

State-region relations involve negotiations over the power to (re)-constitute local spaces. While in federal states, power-sharing ostensibly gives regions a role over many space-making decisions, power asymmetries affect this role. Where centralization trends may erode regional agency, law can provide an important tool by which regions can assert influence. We examine a case where, in response to ...

Free-base <i>meso</i>-triarylcorroles have been found to undergo oxidative coupling with an excess of pyrrole in dichloromethane in the presence of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) affording 5/10-pyrrole-appended isocorroles in reasonable yields (35–60%) and in a matter of seconds. The free-base isocorrole ligands could all be complexed to copper with Cu(OAc)₂·H₂O ...

Anaerobic oxidation of methane (AOM) by methanotrophic archaea is an important sink of this greenhouse gas in marine sediments. However, evidence for AOM in freshwater habitats is rare, and little is known about the pathways, electron acceptors, and microbes involved. Here, we show that AOM occurs in anoxic sediments of a sulfate‐rich lake in southern Switzerland (Lake Cadagno). Combined AOM‐rate ...

In 1992, the constitution and future of Norwegian medieval and historical archaeology was debated in META. The discussion concerned the definition “historical archaeology” itself, and the potential need for this subfield to be established as a discipline in its own right. The aim was to strengthen a weak academic framework for this branch of archaeology. In the end, such a separate discipline was ...

The emerging crisis of antimicrobial resistance calls for the development of new therapeutic drugs. Antimicrobial peptides (AMPs), found in a variety of species as part of the host-defence mechanisms, serves as promising candidates for clinical use. Studies of well-known AMPs like lactoferrin have lead to the preparation of short cationic AMPs (CAPs) with broad spectrum antimicrobial activity against ...

Although teachers’ professional identities have been the subject of extensive study, the field still lacks knowledge about the development of a professional identity for mentor teachers. These teachers take on multifaceted professional roles as teachers and teacher educators. In the present paper, we investigate the professional identity of mentor teachers partnered with two universities in Norway. ...

Security, privacy, transparency, consent, and data sharing are major challenges that healthcare institutions must address today. The explosion of the Internet of Things (IoT), the enactment of the General Data Protection Regulation (GDPR), the growing trend of patients self-managing their diseases, and the eagerness of patients to share their self-collected health data with primary and secondary ...

In 1987, the late German chemist Peter Hofmann of the University of Heidelberg wrote: “We still have a long way to go until a computation will be able to compete with or to substitute a lab experiment... one could then conclude that theoretical work in this field—not being quantitatively reliable anyhow—is rather useless, except for the purpose of keeping theorists busy.” However, Hofmann continued: ...
