In this thesis, shift in diet of Arctic foxes on Svalbard over a long time frame was analyzed. The Svalbard Arctic fox is a generalist who links the terrestrial and marine ecosystems. The objectives were 1) investigate whether there are spatial and temporal trends in Arctic fox diet on Svalbard, 2) determine how important the changes in the environmental variables are for dietary shifts of the Arctic ...

It has commonly been proposed that the development of complex life is tied to increases in atmospheric oxygenation. However, there is a conspicuous gap in time between the oxygenation of the atmosphere 2.4 billion years ago (Ga) and the first widely-accepted fossil evidence for complex eukaryotic cells . At present the gap could either represent poor sampling, poor preservation, and/or difficulties ...

New species of Lepechinella, L. norvegica sp. nov. and L. victoriae sp. nov., from the North East Atlantic are described together with the new, closely related genus and species Lepesubchela christinae gen. et sp. nov. Lepechinella arctica Schellenberg, 1926 from north of Spitsbergen and Lepechinella schellenbergi Stephensen, 1944 from Greenland are redescribed. A key to the species of Atlantic ...

Background: We present a method that utilizes DNA methylation profiling for prediction of the cytogenetic subtypes of acute lymphoblastic leukemia (ALL) cells from pediatric ALL patients. The primary aim of our study was to improve risk stratification of ALL patients into treatment groups using DNA methylation as a complement to current diagnostic methods. A secondary aim was to gain insight into ...

Data-driven research is increasingly becoming fueled by access to open datasets, often shared publicly on the Internet. However, many research projects study sensitive data. They cannot easily participate in this shift as access to their data is significantly controlled by ethical and regulatory constraints. This paper discusses the requirements for building a service that enables sensitive data for ...

LTX-315 has been developed as an amphipathic cationic peptide that kills cancer cells. Here, we investigated the putative involvement of mitochondria in the cytotoxic action of LTX-315. Subcellular fractionation of LTX-315-treated cells, followed by mass spectrometric quantification, revealed that the agent was enriched in mitochondria. LTX-315 caused an immediate arrest of mitochondrial ...

In an earlier paper, an alternative method for how to solve the frequency analysis problem was offered. The object of the present paper is to bring about how to handle situations where the frequencies are close to each other or there is an amplitude that is really small.

Aim A focal task for invasion biology is to identify the environmental variables and biological traits that set and underpin realised and potential habitats of invasive species. Ecophysiology provides powerful empirical knowledge that connects theory with natural phenomena and may improve the accuracy of species distribution modelling. We used the introduced Kamchatka red king crab Paralithodes ...

Avhandlingen gir en fremstilling av de rettigheter og plikter som tilfaller sender og avlaster overfor transportøren ved gjennomføring av stykkgodstransport. Avhandlingen retter seg primært mot linjefarten, men de fleste reglene vil gjelde tilsvarende ved øvrig stykkgodsfart.

The transition from photochemical to digital has without doubt profoundly affected filmmaking and film distribution. But digitization also has consequences to the preservation and exhibition of films produced in the analogue era. The advantages of digitization of film are obvious: the audience gets easy access to a digital copy and, at the same time, the photochemical original (or what is left ...
