Body alignment is a spontaneous response documented in a variety of animals, including songbirds, however the biological significance of this behavior remains elusive for most taxa. Migratory songbirds rely on an endogenous migration program to migrate, and extract navigational information from celestial and magnetic cues. To investigate the body alignment behavior, the resting position of individ

Fabrication of CoNb2O6 thin films was possible through spin-coating an alkali-free, aqueous solution of a polyoxoniobate ([Nb10O28]6-, Nb10) and a cobalt nitrate (Co(NO3)2), followed by annealing. The results showed that depending on the calcination conditions, minor phases of unreacted Co3O4 and β-Nb2O5 may form alongside the columbite CoNb2O6 phase. However, optimizing the calcination conditions

Nearly all multicellular organisms reproduce sexually, whereas asexual reproduction is predominant in unicellular species. However, it is unclear why we see such a tight co-occurrence between multicellularity and sex. Here, we investigate the effect sexual reproduction has on the evolution of multicellularity in the green algae, Chlamydomonas reinhardtii, specifically on the variation and novel ph

Brasilia, Brazil’s capital, is a city designed under the modernist precepts of the 60s. Its urbanistic plan is defined in four urban scales. Each of these occupies a different location in the city and has its own characteristics, which will be explored in this work. Especially the scale of the city center, which will be the focus of this project. Regional and local analyses were key to understand

Let f be a holomorphic self-map of the unit disc. We show that if log(1−|f(z)|) is integrable on a sub-arc of the unit circle, I, then the set of Carathéodory angular derivatives of f on I is a countable union of Beurling-Carleson sets of finite entropy. Conversely, given a countable union of Beurling-Carleson sets, E, we construct a holomorphic self-map of the unit disc, such that its set of Cara

This thesis investigates buyer preferences in the procurement of Internationally Transferred Mitigation Outcomes (ITMOs) under Article 6.2 of the Paris Agreement, which facilitates international cooperation through carbon markets. As ITMO markets are still in the early stages of development, uncertainties regarding regulatory frameworks, environmental integrity, and procurement strategies have eme

År 2024 är det 50 år sedan riksdagen slutligt beslutade att införa den nuvarande regeringsformen. Jubileet har fått relativt mycket uppmärksamhet. Riksdagen har byggt upp en särskild webbplats med information och det har givits ut minst tre forskningsantologier med anledning av jubileet.I detta temanummer ger statsvetare och jurister sina perspektiv på centrala teman med anknytning till den nu fem

This paper analyses the role of the Organization of Islamic Cooperation (OIC) and Islamic Development Bank (IsDB) during crises, considering their limits and potential.

Major political events become a dominant topic of the discussions in the countries involved, and various actors, often other than political parties, take a stance towards them. The withdrawal of the UK from the European Union as a result of the 2016 UK referendum was one of those, and a quite polarised atmosphere from supporters of both sides was observed in the UK and the rest of Europe since the

BACKGROUND: After over a decade of developments in field collection, laboratory methods and advances in high-throughput sequencing, contamination remains a key issue in ancient DNA research. Currently, human and microbial contaminant DNA still impose challenges on cost-effective sequencing and accurate interpretation of ancient DNA data.RESULTS: Here we investigate whether human contaminating DNA

Atmospheric inverse modelling has become an increasingly useful tool for evaluating emissions of greenhouse gases including methane, nitrous oxide, and synthetic gases such as hydrofluorocarbons (HFCs). Atmospheric inversions for emissions of CO2 from fossil fuel combustion (ffCO2) are currently being developed. The aim of this paper is to investigate potential errors and uncertainties related to

The projected ocean acidification (OA) associated with increasing atmospheric CO2 alters seawater chemistry and hence the bio-toxicity of metal ions. However, it is still unclear how OA might affect the long-term resilience of globally important marine microalgae to anthropogenic metal stress. To explore the effect of increasing pCO2 on copper metabolism in the diatom Thalassiosira pseudonana (CCM

Bakgrund: Fler individer väljer att få dö i sitt eget hem. Syftet med palliativ vård är att främja livskvalitet och lindra lidande för individer med obotlig sjukdom. Sjuksköterskan har ett övergripande omvårdnadsansvar inom den palliativa vården och behöver kunna vara självständig och kunna fatta egna beslut. Det ställer höga krav på sjuksköterskan som arbetar i denna komplexa arbetsmiljö. Sjukskö

Under the UK-focused Greenhouse gAs and Uk and Global Emissions (GAUGE) project, two new tall tower greenhouse gas (GHG) observation sites were established in the 2013/2014 Northern Hemispheric winter. These sites, located at existing telecommunications towers, utilized a combination of cavity ring-down spectroscopy (CRDS) and gas chromatography (GC) to measure key GHGs (CO2, CH4, CO, N2O and SF6)

Radon gas is the largest source of public exposure to naturally occurring radioactivity. However, radon is also a useful tracer for understanding atmospheric processes, assessing the accuracy of chemical transport models, and enabling integrated emissions estimates of greenhouse gases. A sound metrological system for low level atmospheric radon observations is therefore needed for the benefit of t

We investigate the problem of low-complexity, high-dimensional channel estimation with beamspace observations, for the purpose of localization. Existing work on beamspace ESPRIT (estimation of signal parameters via rotational invariance technique) approaches requires either a shift-invariance structure of the transformation matrix, or a full-column rank condition. We extend these beamspace ESPRIT
