Natural fractures significantly contribute to improved reservoir quality and recovery factor, especially in carbonate reservoirs. It is important to characterize the matrix and fracture properties, as well as their interaction, in order to describe the natural fracture system and improve the understanding of its effects on a reservoir. This study integrates multi-scale outcrop data from central ...

The Brusque Metamorphic Complex is situated in the northern part of the Dom Feliciano Belt in the state of Santa Catarina, southeastern Brazil. The complex is composed of Neoproterozoic sequences of volcanic and sedimentary rocks, which were folded and metamorphosed at greenschist to low-amphibolite facies conditions. U-Pb dating of detrital zircon grains in five samples of clastic metasedimentary ...

This thesis combines a geological model with a mathematical model to describe the vertical propagation of a gas plume through layers with different physical properties. The geological model is based on geophysical data from the Sørvestsnaget Basin and the mathematical model is derived based on the classical Buckley-Leverett theory for two-phase flow. The model estimates the velocity of a vertical ...

This study investigates the glacial dynamics of Barentsjøkulen, a small ice cap located on Barentsøya, Svalbard. In order to reconstruct Barentsjøkulen’s glacial history, three geomorphological maps of the glacier forefields of its main outlet glaciers, Besselsbreen, Duckwitzbreen and Freemanbreen, were created. The maps cover a total area of ca. 117 km2 and were generated based on swath bathymetric ...

It is estimated that 5-10% of breast cancers (BC) and 25% of ovarian cancers (OC) are caused by inherited sequence variants in genes. In the mid 90’s, the two genes BRCA1 and BRCA2 were discovered to be directly associated with increased risk of BC and OC. Molecular screening of these two genes has revealed several disease causing variants as well as variants of unknown clinical significance (VUS). ...

We show that indications of spatial dispersion effects on mineral oil slicks are observed by space-borne multipolarization synthetic aperture radar. This is readily perceived by eye when correlating multipolarization synthetic aperture radar observables with the ship track of the dispersion vessel. We investigate real full-polarimetric (linear transmit/linear receive) as well as simulated and real ...

Refinements of some limit Hardy-type inequalities are derived and discussed using the concept of superquadracity. We also proved that all three constants appearing in the refined inequalities obtained are sharp. The natural turning point of our refined Hardy inequality is p=2 and for this case we have even equality.

This article examines the fathering practices of men in mobile work in the petroleum industry in Norway. In particular, it analyses the spatial mobility of these men and how their absence and presence impact their fathering. Drawing on insights from gendered migration and mobility studies, fathering and ‘new material’ approaches, this article nuances the understanding of current fathering practices ...

Venous thromboembolism (VTE) is a common disease with an incidence of 1–2 per 1000 individuals. VTE is a collective term for deep vein thrombosis and pulmonary embolism. Extracellular vesicles (EVs) are lipid-membrane-bound spherical vesicles that bud off from the cells upon activation and apoptosis. Their size varies between 30 nm and 1 μm. Recent advances in experimental and observational studies ...

This paper shows that Envisat ASAR data are degraded by a small periodic variation in gain between internal calibration cycles of the antenna, which introduces a significant bias when we try to estimate line-of-sight surface velocities from the estimated Doppler frequency shifts. We investigate the impact of the gain problems on the derived surface velocity product and propose a simple correction ...
