Bruk av FEM-modellering til kapasitetsundersøkelser av momentoverførende knutepunkter i stål
2021
Master's thesis in Civil and structural engineering (BYG508) Eurocode 3 provides a rough analytical method to estimate the capacity of a steel joint by derivingthe overall behavior from its components. Numerical methods such as the finite element method(FEM) enable accurate simulation of joint behavior. However, there is no direct guidelines inthe Eurocodes for utilizing numerical methods to document the capacity of moment-resisting steeljoints. This master thesis investigates how FEM can be used to evaluate and document the capacityof such joints. A literature review that includes relevant normative documentation and researcharticles dealing with the use of FEM has been carried out and a s…

Comparison of Different Construction Methods for Multi‐Storey Timber Buildings
2018
Master's Thesis Civil and Constructional Engineering BYG508 - University of Agder 2018 In this master thesis, different timber materials and construction methods are examined concern‐ing the application in multi‐storey timber buildings. Although wood as a construction material has many advantages, it is today only used very little for larger constructions, concrete and steel dominate the building industry. Planners and engi‐neers are often lacking necessary expertise to utilise timber in a modern, effective way. In order to promote the development of modern, efficient multi‐storey timber buildings, the goal of this master thesis is to contribute to a better understanding of the wood’s chara…

On-surface Synthesis of a Chiral Graphene Nanoribbon with Mixed Edge Structure.
2020
Abstract Chiral graphene nanoribbons represent an important class of graphene nanomaterials with varying combinations of armchair and zigzag edges conferring them unique structure‐dependent electronic properties. Here, we describe the on‐surface synthesis of an unprecedented cove‐edge chiral GNR with a benzo‐fused backbone on a Au(111) surface using 2,6‐dibromo‐1,5‐diphenylnaphthalene as precursor. The initial precursor self‐assembly and the formation of the chiral GNRs upon annealing are revealed, along with a relatively small electronic bandgap of approximately 1.6 eV, by scanning tunnelling microscopy and spectroscopy.

Dominus qui incepit ipse perficiat: exhortaciones de fray Josep Mercader a las monjas dominicas del monasterio de Montesión en Barcelona (1740-1745)
2016
Resumen: De entre la galeria de personajes interesantes que nos ofrece el convento dominicano de Santa Catalina virgen y martir de Barcelona en el siglo XVIII destaca fray Josep Mercader (profesion 1720-1779). Un apartado importante aunque «intimo» de su obra lo constituyen las once breves exhortaciones que entre los anos 1740-1745 dirigio a las monjas dominicas del monasterio barcelones de Montesion con ocasion de las ceremonias de recepcion y profesion. En estos 20 folios podemos encontrar el discurso que un dominico cualificado dirigio a las monjas de clausura de su orden en dos momentos tan significativos de su trayectoria religiosa. Palabras clave: Josep Mercader, Dominicos (frailes y …
Chemical composition of modern and fossil hippopotamid teeth and implications for paleoenvironmental reconstructions and enamel formation – Part 2: A…
2012
Abstract. For reconstructing environmental change in terrestrial realms the geochemistry of fossil bioapatite in bones and teeth is among the most promising applications. This study demonstrates that alkaline earth elements in enamel of Hippopotamids, in particular Ba and Sr are tracers for water provenance and hydrochemistry. The studied specimens are molar teeth from Hippopotamids found in modern and fossil lacustrine settings of the Western Branch of the East African Rift system (Lake Kikorongo, Lake Albert, and Lake Malawi) and from modern fluvial environments of the Nile River. Concentrations in enamel vary by ca. two orders of magnitude for Ba (120–9336 μg g−1) as well as for Sr (9–21…
Toward the development of metal-based synthetic nucleases: DNA binding and oxidative DNA cleavage of a mixed copper(II) complex with N-(9H-purin-6-yl…
2009
Abstract The complex [Cu(N9-ABS)(phen) 2 ]·3.6H 2 O, H 2 N9-ABS = N -(9 H -purin-6-yl)benzenesulfonamide and phen = 1,10-phenanthroline, has been synthesized and then characterized with the aid of X-ray diffraction, analytical, and spectroscopic techniques. The geometry of Cu(II) is distorted square pyramidal with the equatorial positions occupied by three N atoms from two phenantroline molecules and one N atom from the adenine ring of the sulfonamide ligand. The interaction of the complex with DNA was studied by means of viscosity measurements and fluorescence spectroscopy. The results pointed to a classic intercalation of the complex between the DNA base pairs. The complex was found to b…
Activity from the Be/X-ray binary system V0332+53 during its intermediate-luminosity outburst in 2008
2015
Aims: We present a study of the Be/X-ray binary system V 0332+53 with the main goal of characterizing its behavior mainly during the intermediate-luminosity X-ray event on 2008. In addition, we aim to contribute to the understanding of the global behavior of the donor companion by including optical data from our dedicated campaign starting on 2006. Methods: V 0332+53 was observed by RXTE and Swift during the decay of the intermediate-luminosity X-ray outburst of 2008, as well as with Suzaku before the rising of the third normal outburst of the 2010 series. In addition, we present recent data from the Spanish ground-based astronomical observatories of El Teide (Tenerife), Roque de los Muchac…
