The timing of surgical resection of synchronous liver metastases from colorectal cancer has been debated for decades. Several strategies have been proposed, but high-level evidence remains scarce. Simultaneous resection of the primary tumour and liver metastases has been described in numerous retrospective audits and meta-analyses. The potential benefits of simultaneous resections are the eradication ...

A key step in the process of isolating microbial natural products is the preparation of an extract from a culture. This step determines which molecules will be available for detection in the subsequent chemical and biological analysis of a biodiscovery pipeline. In the present study we wanted to document potential differences in performance between liquid–liquid extraction using ethyl acetate ...

Den siste uka har det pågått en debatt i media om trakassering av kvinner i fiskeryrket. Kvinnelige fiskere har stått fram med rystende historier. Ukulturen i fiskerinæringen er et kulturelt og strukturelt problem.

Satellite observations of pan-Arctic sea ice thickness have so far been constrained to winter months. For radar altimeters, conventional methods cannot differentiate leads from meltwater ponds that accumulate at the ice surface in summer months, which is a critical step in the ice thickness calculation. Here, we use over 350 optical and synthetic aperture radar (SAR) images from the summer months ...

The microbial key players at methane seeps are methanotrophic archaea and sulfate-reducing bacteria. They form spherical aggregates and jointly mediate the sulfate-dependent anaerobic oxidation of methane (SD–AOM: CH4 + SO42– → HCO3– + HS– + H2O), thereby inducing the precipitation of authigenic seep carbonates. While seep carbonates constitute valuable archives for molecular fossils of SD–AOM-mediating ...

We report on methane (CH₄₎ stable isotope (d¹³C and d² H) measurements from landfast sea ice collected near Barrow (Utqiagvik, Alaska) and Cape Evans (Antarctica) over the winter-to-spring transition. These measurements provide novel insights into pathways of CH₄ production and consumption in sea ice. We found substantial differences between the two ...

Faults commonly form loci for high fluid flux in sedimentary basins, where fluids, rocks and deformation processes frequently interact. Here, we elucidate the interaction of fluid flow, diagenesis and deformation near basin-bounding faults in sedimentary basins through a study in the vicinity (0–3.5 km) of the Dombjerg Fault in the NE Greenland rift system. Due to fault-controlled fluid circulation, ...

<p>The classical Fourier Analysis has been developed in an almost unbelievable way from the first fundamental discoveries by Fourier. Especially a number of wonderful results have been proved and new directions of such research has been developed e.g. concerning Wavelets Theory, Gabor Theory, Time-Frequency Analysis, Fast Fourier Transform, Abstract Harmonic Analysis, etc. One important reason for ...

BAKGRUNN - MOT Robust ungdom 12–16 er et universelt forebyggende og helsefremmende tiltak rettet mot ungdom i alderen 12–16 år. Målet er å utvikle varmere å tryggere samfunn gjennom å utvikle robuste ungdommer som inkluderer alle. Tiltaket består av tolv klassebesøk over alle årene i ungdomsskolen der ulike tema behandles og gjennomgås etter en fast plan. I tillegg forekommer det andre miljøskapende ...

Attending school on a regular basis and completing school is usually seen as a precondition for students’ academic, emotional, and social learning and development. However, some students struggle with school attendance problems (SAPs) for a myriad of reasons. Homeschooling is a topic of concern in long-term or problematic SAP cases. Some scholars claim that school absenteeism might increase and be ...
