Nye innovative bedrifter på Agder
2014
Masteroppgave Innovasjon og kunnskapsutvikling ME 513 - Universitetet i Agder 2014 Etablering av innovative bedrifter er viktig for økonomisk vekst og for vekst i sysselsetting. I denne oppgaven har jeg studert nye innovative bedrifter på Agder, som er etablert i perioden 2009 til 2013. Jeg ønsket å studere dette temaet for å finne ut av hvem det er som er med på å løfte Agder- regionen «opp og frem». Populasjonen jeg har studert er bedrifter som har fått landsdekkende etablerertilskudd fra Innovasjon Norge i tidsrommet 2009 til 2013. Kravet for å få tildelt et slikt tilskudd er at bedriften er etablert på bakgrunn av en innovasjon. Gjennom oppgaven benytter jeg meg av stortingsmeldingens d…
Multi-channel receptors based on thiopyrylium functionalised with macrocyclic receptors for the recognition of transition metal cations and anions.
2010
We report herein the synthesis and characterization of a family of ligands containing different cation binding sites covalently connected to a thiopyrylium signalling reporter. The receptors L1–L6 are able to signal the presence of certain metal cations via three different channels; i.e. electrochemically, fluorogenically and chromogenically. An acetonitrile solution of L1–L6 shows a bright blue colour due to a charge-transfer band in the 575–585 nm region. The colour variation in acetonitrile of L1–L6 in the presence of the metal cations Ag+, Cd2+, Cu2+, Fe3+, Hg2+, Ni2+, Pb2+ and Zn2+ has been studied. A selective hypsochromic shift of the blue band was found for the systems L4-Pb2+ and L…
Properties of a triazolopyridine system as a molecular chemosensor for metal ions, anions, and amino acids.
2006
The characteristics as a chemosensor of the compound 3-methyl-6,8-di(2-pyridyl)-[1,2,3]triazolo[5',1':6,1]pyrido[2,3-]pyrimidine (1) have been analyzed. Interaction with Cu(2+) produces a quenching of the fluorescence, while interaction with Zn(2+) leads to a quenching of the fluorescence followed by a bathochromic shift. The crystal structure of the Zn(1)(H(2)O)(3)(ClO(4))(2) x H(2)O complex shows the coordination of Zn(2+) through the terpyridine moiety. The octahedral site is completed by three water molecules. Interactions of the Zn(2+) complex with the anions sulfate, nitrate, nitrite, and dihydrogenphosphate in ethanol produce hypsochromic shifts and restoration of the fluorescence wh…
Substituent Effects on the [N-I-N](+) Halogen Bond
2016
We have investigated the influence of electron density on the three-center [N-I-N](+) halogen bond. A series of [bis(pyri din e) io dine](+) and [1,2-bis ( (pyridin e-2-71 ethynyl)b e nze n e)io dine](+) BF4- complexes substituted with electron withdrawing and donating functionalities in the para-position of their pyridine nitrogen were synthesized and studied by spectroscopic and computational methods. The systematic change of electron density of the pyridine nitrogens upon alteration of the para-substituent (NO2, CF3, H, F, Me, OMe, NMe2) was confirmed by N-15 NMR and by computation of the natural atomic population and the pi electron population of the nitrogen atoms. Formation of the [N-…
Formation and growth of palladium nanoparticles inside porous poly(4-vinyl-pyridine) monitored by operando techniques: The role of different reducing…
2017
In this work we followed the formation of palladium nanoparticles, starting from palladium (II) acetate precursor, inside a poly(4-vinylpyridine-co-divinylbenzene) polymer in presence of different reducing agents. The formation and growth of palladium nanoparticles in presence of H-2 was followed as a function of temperature by simultaneous XANES-SAXS techniques, coupled with DRIFT spectroscopy in operando conditions. It was found that the pyridyl functional groups in the polymer plays a fundamental role in the stabilization of the palladium (II) acetate precursor, as well as in the stabilization of the palladium nanoparticles. The effect of a thermal treatment in alcohol (ethanol and 2-pro…
Intern kommunikasjon i Glencore Nikkelverk
2016
Masteroppgave samfunnskommunikasjon- Universitetet i Agder, 2016 Denne masteroppgaven omhandler intern kommunikasjon i Glencore Nikkelverk i Kristiansand. Fokuset er rettet mot interne kommunikasjonsmedier og mediebruk i avdelingene Nikkelelektrolysen og Kontrollrommet. Undersøkelsen omfatter i tillegg ansattes erfaringer med interne kommunikasjonsmedier og ansattes meninger om informasjon som gjelder sikkerhet og forbedringsarbeid. Nikkelverket jobber kontinuerlig med forbedringer som øker produktiviteten, samtidig er sikkerhet det viktigste bedriften fokuserer på hver dag. Bedriften benytter rundt 10 ulike medier for å formidle denne informasjonen til sine ansatte. Disse mediene brukes i …
La storia del ‘Vocabularium iurisprudentiae Romanae’. 1. Il progetto del vocabolario e la nascita dell’interpolazionismo
2017
A close examination of the intersection of printed and unpublished sources allows, in a comprehensive manner, to reconstruct the history of the project of the Vocabularium iurisprudentiae Romanae. Within this unitary framework the idea that interpolationism was based on a lexical motive, and not on a juridical one, is discussed. Eine eingehende Überprüfung von gedruckten und ungedruckten Quellen ermöglicht es, die Projektgeschichte des Vocabularium iurisprudentiae Romanae vollständig zu rekonstruieren. In diesem Rahmen wird die Vorstellung erörtert, nach der hinter der zeitgenössischen Interpolationenkritik ein wesentlich lexikalischer, nicht aber juristischer, Beweggrund zu erblicken sei.
1.5Jy MOJAVE AGN sample and 3FGL data
2016
We use the complete MOJAVE 1.5Jy sample of active galactic nuclei (AGNs) to examine the gamma-ray detection statistics of the brightest radio-loud blazars in the northern sky. We find that 23% of these AGNs were not detected above 0.1GeV by the Fermi-LAT during the four-year 3FGL catalog period partly because of an instrumental selection effect and partly due to their lower Doppler boosting factors. Blazars with synchrotron peaks in their spectral energy distributions located below 10^13.4^Hz also tend to have high-energy peaks that lie below the 0.1GeV threshold of the LAT, and are thus less likely to be detected by Fermi. The non-detected AGNs in the 1.5Jy sample also have significantly l…
MOJAVE. XIII. New 15GHz observations on 1994-2013
2017
We present 1625 new 15GHz (2cm) VLBA images of 295 jets associated with active galactic nuclei (AGNs) from the MOJAVE and 2cm VLBA surveys, spanning observations between 1994 August 31 and 2013 August 20. For 274 AGNs with at least 5 VLBA epochs, we have analyzed the kinematics of 961 individual bright features in their parsec-scale jets. A total of 122 of these jets have not been previously analyzed by the MOJAVE program. In the case of 451 jet features that had at least 10 epochs, we also examined their kinematics for possible accelerations. At least half of the well-sampled features have non-radial and/or accelerating trajectories, indicating that non-ballistic motion is common in AGN je…
Challenging equal temperament : perceived differences between twelve-tone equal temperament and twelve fifth-tones tuning
2017
A listening experiment was arranged to evaluate perceptual preferences between two musical tuning systems: twelve-tone equal temperament (i.e. the current international standard) and twelve fifth-tones tuning. The latter being a system that, according to its author Maria Renold, provides a more accurate and aurally genuine reproduction of musical harmonics. Hence, it is considered a superior tuning method compared to the equal temperament tuning. 34 participants (mainly experienced musicians) evaluated realistic musical stimuli consisting of intervals, chords and simple musical sequences using a grand piano timbre. Results showed that the standard twelve-tone equal temperament system was fo…
