Corroles are an important class of contracted porphyrin analogues. Since quasi-one-pot syntheses of corroles were first reported in 1999, their coordination chemistry has been extensively studied. In the course of this thesis, the “periodic table of corroles” has been extended by two new elements, rhenium and technetium. Except from an accidental synthesis of an ReVO corrole via ring contraction ...

The University of Tromsø has carried out multiple studies by master students on unstable rock slopes (URS) in Troms County, Northern Norway. This thesis differs from other studies in Troms as Skredkallen is located in Pre-Cambrian rocks as part of West Troms Basement Complex (WTBC). The rocks of the WTBC have been subjected to multiple phases of deformation, and the main structural features from ...

Fluctuations in plasma electron density may play a role in solar coronal energy transport and the dissipation of wave energy. Transcoronal spacecraft radio sounding observations reveal frequency fluctuations (FFs) that encode the electron number density disturbances, allowing an exploration of the coronal compressive wave and advected inhomogeneity models. Primary FF observations from MESSENGER 2009 ...

Subsequent to a widespread hiatus at the top of the Permian on western Svalbard, the Triassic Vardebukta, Tvillingodden and Bravaisberget formations were deposited. In this thesis, the sedimentology, geochemistry and diagenesis are investigated to determine the depositional environment and basinal setting of the Triassic deposits. In the investigated profile on Mariaholmen, only the upper part ...

The eastern parts of the northern Barents Sea is a little explored sector of the Barents Sea which currently is not open for petroleum activity. This thesis focuses on the processes and mechanisms controlling gas seepage activity in the Olga basin and Storbanken high. 2D seismic and bathymetric data has been correlated with water column acoustic data to identify gas bubbles in the water column and ...

Øya Vanna nordøst i Vest-Troms gneisregionen består av TTG-gneiser (2.8 Ga), 2.4 Ga mafiske intrusivganger, en overliggende metasedimentær enhet i sør kalt Vannagruppen intrudert av en dioritt (sill) datert til 2221 ± 3 Ma, og Skipsfjorddekket i nord, en allokton enhet skjøvet mot SØ. Studieområdet befinner seg sørøst på Vanna, i området Larstangen-Fakkekeila. Her opptrer metasedimentære bergarter ...

Vannas geologi er unik, og strukturer av komplekse folde- og skyvebelter med antatt sensvekofennisk alder karakteriserer deformasjoner av neoarkeiske tonalittiske gneisbergarter (2,9-2,4 Ga), paleoproterozoiske metasedimentære og intrusive bergarter på øya, helt nord i Vest- Troms gneisregionen. Hovedhensikten med dette arbeidet har vært kartlegging og strukturell analyse av antatte metasedimentære ...

The focus of this study has been to combine structural data with morphological observations and displacement data to characterise the unstable rock slopes at Mellomfjellet. The site contains two instabilities (Mellomfjellet 1 and 2) and is located along a west-facing slope in Reisadalen, a glacially eroded valley, in Nordreisa, Troms. The bedrock consists mainly of Caledonian amphibolite and hornblende ...

Climate change is one of the most talked about topics in the world at the moment. In the context of man induced Global Warming, there are many proposed ideas on how to combat its effects and many more are still needed. We propose employing nudge theory to persuade people into using environmentally friendly modes of transport through a software application. This thesis focuses on the data management ...

Breitfussins are a group of a closely related heterocyclic compounds. They consist of a tetracyclic structure with an indole, an oxazole and a pyrrole. The breitfussins exhibit interesting biological activity and analogues synthesis and biological evaluation is ongoing. Phorbazoles have a structural similarity with breitfussins in which a phenol replaces the indole. As a part of this, synthesis of ...
