X-ray absorption spectroscopy (XAS) is performed to study changes in the electronic structures of colossal magnetoresistance (CMR) and charged ordered (CO) La1-x Ca x MnO3 manganites with respect to temperature. The pre-edge features in O and Mn K-edge XAS spectra, which are highly sensitive to the local distortion of MnO6 octahedral, exhibit contrasting temperature dependence between CMR and CO s
We show how probabilistic numerics can be used to convert an initial value problem into a Gauss–Markov process parametrised by the dynamics of the initial value problem. Consequently, the often difficult problem of parameter estimation in ordinary differential equations is reduced to hyper-parameter estimation in Gauss–Markov regression, which tends to be considerably easier. The method’s relation
The homogenization of the Maxwell equations at fixed frequency is addressed in this paper. The bulk (homogenized) electric and magnetic properties of a material with a periodic microstructure are found from the solution of a local problem on the unit cell by suitable averages. The material can be anisotropic and satisfies a coercivity condition. The exciting field is generated by an incident field
The use of this material under current use conditions is supported by the existing information. This material was evaluated for genotoxicity, repeated dose toxicity, developmental toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity, skin sensitization potential, as well as, environmental safety. Repeated dose toxicity was determined using a suitable read across analog to hav
The use of this material under current use conditions is supported by the existing information. This material was evaluated for genotoxicity, repeated dose toxicity, developmental toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity, skin sensitization potential, as well as, environmental safety. Repeated dose toxicity was determined to have the most conservative systemic exp
Due to anatomical restrictions, the inflammatory response to intracerebral bacterial infections exposes swollen brain tissues to pressure and ischemia, resulting in life-threatening damage. Rapid diagnosis and immediate empirical antibiotic therapy is highly important. However, diagnosing meningitis in patients after neurosurgery is complicated, due to brain tissue damage and changes in cerebrospi
The local density theory is developed by Hohenberg, Kohn and Sham is extended to the spin polarized case. A spin dependent one- electron potential pertinent to ground state properties is obtained from calculations of the total energy per electron made with a `bubble' (or random phase) type of dielectric function. The potential is found to be well represented by an analytic expression corresponding
Arctic tundra ecosystems are warming almost twice as fast as the global average. Permafrost thaw and the resulting release of greenhouse gases from decomposing soil organic carbon have the potential to accelerate climate warming. In recent decades, Arctic tundra ecosystems have changed rapidly, including expansion of woody vegetation, in response to changing climate conditions. How such vegetation
Using panel micro data fro\m Community Innovation Survey in the Czech Republic, Norway and the UK, we estimate dynamic random effects models, in which the innovation output of firms is the function of their cooperative behaviour and other observed characteristics, while accounting for unobserved heterogeneity. The results indicate that the capacity of firms to build on external domestic linkages i

The adage “think global, act local” can be a fitting description of how to address climate change. Municipalities are often responsible for implementing the measures required to reduce greenhouse gas emissions and shift to a more climate-neutral development trajectory. However, there is a vast spectrum of municipal ambition regarding climate, and not all municipalities manage to have robust and am
Community based approaches to conservation in the developing world have generally been criticized for not meeting their goals of sustainable conservation and local development. Inadequate local participation and inequitable benefits sharing among others are some of the major concerns. In Tanzania wildlife management areas (WMAs) are one of the forms of community-based wildlife conservation initiat
Notice taken towards the position of philanthropy in sub-Saharan Africa has increased in the lastdecade. Increasing amounts of private wealth, charity and philanthropy initiatives are changing the landscape earlier characterised by traditional forms of philanthropy that have been practised between people and communities. This study explored the central conversation around philanthropy in sub-Sahar
One of the issues of modern cities is their urban design which is not structured to allow human interaction and promote a feeling of community within their inhabitants. The constant growth and shortages of land are cause to the global housing crisis which requires densification. In the current capitalistic context, urban design becomes just another pawn of this profit making machine, causing gentr
The drastic changes in infrastructure and arrival of luxury tourism to South Sinai has brought the global world at the doorstep of the region’s nomadic bedouins. The ever-expanding global influence has given birth to a generation of young bedouin women who absorb the surrounding new ideals, behaviors and understandings, blending them with their tribal culture. This has created identity hybridities
In this thesis, the relationship between people and places is investigated through examining how migrants in Vienna create place attachment to food markets in the city. A place attachment is understood as the emotional bond that forms between an individual and a specific space, the theoretical foundation of this thesis lies within emotional geography, a sub-field of human geography which examines
This thesis addresses the ongoing debate on the involvement of Chinese nationals in Ghana's artisanal and small-scale gold mining (ASGM) sector. Despite the Minerals and Mining Law, Act 703 (2006) prohibiting foreigners from engaging in ASGM, it is reported that about 50,000 Chinese nationals have migrated to rural Ghana to engage in illegal mining activities. This has caught the attention of
Locally induced, magnetic order on the surface of a topological insulator nanowire could enable room-temperature topological quantum devices. Here we report on the realization of selective magnetic control over topological surface states on a single facet of a rectangular Bi2Te3 nanowire via a magnetic insulating Fe3O4 substrate. Low-temperature magnetotransport studies provide evidence for local
