GeneSys-Beet: A model of the effects of cropping systems on gene flow between sugar beet and weed beet
2008
A weedy form of the genus Beta, i.e. Beta vulgaris ssp. vulgaris (hence ''weed beet'') frequently found in sugar beet is impossible to eliminate with herbicides because of its genetic proximity to the crop. It is presumed to be the progeny of accidental hybrids between sugar beet (ssp. vulgaris) and wild beet (ssp. maritima), or of sugar beet varieties sensitive to vernalization and sown early in years with late cold spells. In this context, genetically modified (GM) sugar beet varieties tolerant to non-selective herbicides would be interesting to manage weed beet. However, because of the proximity of the weed to the crop, it is highly probable that the herbicide-tolerance transgene would b…

Right Restriction or Restricting Rights? The UK Acts to Address COVID-19
2020
The UK was initially slow to adopt measures to address the COVID-19 pandemic. However on 23 March 2020 and following escalating infection and mortality rates, the government introduced the most restrictive measures on movement in modern UK history. These lockdown measures which introduced sweeping limitation on movement outside the home were introduced through statutory legislation: regulations which were made by the government and not debated nor legislated by Parliament. This article considers the issues the UK?s legal responses to address the COVID-19 raises in terms of democracy, human rights and the rule of law
Timing of the accreting millisecond pulsar IGR J17591-2342: evidence of spin-down during accretion
2020
We report on the phase-coherent timing analysis of the accreting millisecond X-ray pulsar IGR J17591-2342, using Neutron Star Interior Composition Explorer (NICER) data taken during the outburst of the source between 2018 August 15 and 2018 October 17. We obtain an updated orbital solution of the binary system. We investigate the evolution of the neutron star spin frequency during the outburst, reporting a refined estimate of the spin frequency and the first estimate of the spin frequency derivative ($\dot{\nu} \sim -7\times 10^{-14}$ Hz s$^{-1}$), confirmed independently from the modelling of the fundamental frequency and its first harmonic. We further investigate the evolution of the X-ra…
New insights on the puzzling LMXB 1RXS J180408.9-342058: the intermediate state, the clocked type-I X-ray bursts and much more
2019
1RXS J180408.9--342058 is a low mass X-ray binary hosting a neutron star, which shows X-ray activity at very different mass-accretion regimes, from very faint to almost the Eddington luminosity. In this work, we present a comprehensive X-ray study of this source using data from the Neil Gehrels Swift Observatory, NuSTAR and INTEGRAL/JEM-X. In order to follow the spectral evolution, we analysed the 2015 outburst using Swift data and three Nustar observations. Besides the canonical hard and soft spectral states, we identified the rarely observed intermediate state. This was witnessed by the appeareance of the accretion disk emission in the spectrum (at $kT_{\rm disk}$ $\sim$0.7 keV) and the s…
Space-VLBI phase-reference mapping and astrometry
2001
We present 5 GHz space-VLBI observations of the quasar pair B1342+662/B1342+663 that demonstrate the feasibility of phase-reference techniques using an antenna in space. The space-based data were taken by the satellite HALCA, of the space-VLBI mission VSOP. From residual (referenced) phases we derive an upper bound of 10 meters to the uncertainty of the spacecraft orbit reconstruction. An analysis of the phase-reference maps of the sources additionally suggests that the above mentioned uncertaintyis likely not larger than 3 meters. With errors of this magnitude, HALCA is a useful tool for astrometric studies of close pairs of radio sources.
Revisors vurdering av store foretaks rapportering av samfunnsansvar : Hvordan vurderer revisor store foretaks rapportering av samfunnsansvar etter re…
2020
Master's thesis in Accounting and auditing (BE508) Fokuset på samfunnsansvar har de sisteårene økt både blant forbrukere, investorer og næringslivet generelt. Store foretak har siden 2013 vært pålagt å rapportere om sitt samfunnsansvar i henhold til regnskapsloven § 3-3 c. Flere norske selskaper får imidlertid kritikk for sin rapportering. Revisor er i henhold til revisorloven § 5-1 pålagt å kontrollere at selskapenes redegjørelser om samfunnsansvar er i samsvar med lov og forskrift, og om opplysningene er konsistent med årsregnskapet. Denne masteroppgaven diskuterer revisors vurdering av store foretaks bærekraftsrapportering, og har til formål å besvare følgende problemstilling:Hvordan vur…
