The kinetics and mechanism of the reaction between [PtI3(AsPh3)](-) and pyridine in acetonitrile solvent has been studied by use of stopped-flow spectrophotometry. Substitution of iodide trans to arsine is irreversible under the conditions used and takes place via parallel direct and solvolytic pathways. By comparing the rate constants of the direct pathway with literature values of the correspond
The Charter of Fundamental Rights of the European Union has been a legally binding act for ten years. However, ever since entering into the force, it has not been quite clear when the Charter in fact is applicable. During the past years, the EU has been faced by the Rule of law crisis, as called in the academic debate. This thesis aims to clarify when the Charter is applicable and examine whether
In the last decade, news reports about an overall doomed brick-and-mortar retail landscape have grown. The field of commerce has experienced a digital boom, causing an increased shift of businesses from traditional brick-and-mortar retail to the internet. This structural transformation is changing the commercial landscape, putting serious pressure on city centre retail and urban development. Store
The objective of this study has been to create an online system for condition monitoring and diagnosis of a combined heat and power plant in Sweden. The system in question consisted of artificial neural network models, representing each main component of the combined heat and power plant, connected to a graphical user interface. The artificial neural network models were integrated on a power gener
Background/Aims: Data on contact allergy to fragrances in the general population are limited. Data from allergological services suggest that the frequency of contact allergy to fragrances is increasing. The European Dermato-Epidemiology Network (EDEN) Fragrance Study aims to obtain reliable data on the prevalence of contact allergy to fragrances and other sensitizers of the European baseline serie
La chimie des otolithes de poissons sert a associer les poissons a des environnements specifiques. La chimie des otolithes peut aussi potentiellement servir d'outil dans la recherche phylogenetique, comme nous le demontrons ici chez les poissons salmonides et les taxons apparentes. Des cartes bidimensionnelles de la chimie de Zn:Ca dans les otolithes montrent des oscillations annuelles d'amplitude
In the production of ethanol from lignocellulosic material, it is necessary to reach a high ethanol concentration after fermentation. Simply increasing the substrate concentration leads to stirring problems and inhibition of the enzymes and yeast in the process. Batch simultaneous saccharification and fermentation (SSF) of steam-pretreated spruce with 13.7% water-insoluble solids (WIS) (25% total
Contour feathers cover most of the avian body and play critical roles in insulation, social communication, aerodynamics, and water repellency. Feather production is costly and the development of the optimum characteristics for each function may be constrained by limited resources or time, and possibly also lead to trade-offs among the different characteristics. Populations exposed to different env
The present study aimed to investigate how the impact of several factors linked to geography would shape life-history traits in a gregarious species, using the pine processionary moth (PPM) Thaumetopoea pityocampa as a model system. PPM has a wide geographical distribution over the Mediterranean Basin, and it is a strictly gregarious species throughout larval development, where the total reproduct
Denna uppsats utgår från premissen att barns rätt till integritet är en del av barns rätt till deltagande online. Barnrättslagstiftning presenterar i sig ett di-lemma som rör barns rätt till delaktighet och skydd, där en rättighetsbaserad strategi anses vara det mest effektiva sättet att ta itu med dilemmat. En rättig-hetsbaserad strategi förespråkar en balans mellan barns behov av skydd online ocThis thesis starts from the premise that children’s right to privacy is a part and parcel for children’s right to participation online. Children’s rights law inher-ently presents a dilemma relating to children’s right to participation and protec-tion, where a rights-based approached is considered the most effective way to address the dilemma. A rights-based approach is legal framework that can bal
Both the pandemic and Euro crisis posed social risks in terms of unemployment and poverty. Yet, we see a more socially focussed crisis response to the pandemic, whereas the Euro crisis mainly neglected social policy. My thesis asks in how far such social policy crisis response variation can be understood. Hitherto literature usually focusses on instiutionalist arguments that are unable to bridge s
In yet another alarming development in Syria, the waters of the Euphrates River have declined to critically low levels in 2021. The unprecedented low water levels of the Euphrates put nearly 5.5 million Syrians at risk as they depend on the Euphrates basin for drinking water and agricultural production. This study examines the phenomenon of water shortages in the Euphrates River whilst utilising t
Supported lipid bilayers are a popular in situ artificial bilayer model where a lipid solution is deposited on a surface. Usually the supported lipid bilayers consist of only 2-3 lipids and the problem with that is that they do not represent the biological membrane very well. In this project Pichia pastoris lipids were used to form supported lipid bilayers at different pH, temperature and differen
Changing environmental conditions can generate physiological stress in birds, which subsequently can lead to the development of an altered diet. In addition to their energetic properties, dietary fatty acids (FAs) have been linked to several important physiological processes in birds, but still the knowledge of their effect on avian ecology is limited. In this study, I examine the fatty acid compo
Background: Little is known about the causes of thyroid cancer, but insulin-like growth factor-I (IGF-I) might play an important role in its development due to its mitogenic and antiapoptotic properties. Methods: This study prospectively investigated the association between serum IGF-I concentrations and risk of differentiated thyroid carcinoma in a case-control study nested within the European Pr
This work studies osteoinduction and bone conduction in polyvinyl alcohol-tetraethylorthosilicate-alginate-calcium oxide (PTAC) biocomposite cryogels along with the synergistic effect of electrical stimulation. In vitro osteoinduction of C2C12 myoblast towards osteogenic lineage is demonstrated through alkaline phosphatase assay, scanning electron microscopy and energy dispersive X-ray spectroscop
Changes in vascular tone brought about by electrical field stimulation were studied in isolated guinea-pig and monkey pial arteries, using stimulus intensities similar to, or weaker than, those usually utilized by other investigators. In the guinea-pig, excitation of the smooth muscle cells was easily induced, even at low intensity stimulus parameters. This contraction faded upon repeated stimulat
