Late Permian mass extinction (LPME) research has focused primarily on Tethyan sections because it is believed that these successions are more complete than those from other localities, and provide a more comprehensive record of the largest, most devastating extinction event in Earth history. The Kisejin section, a previously undocumented mid-Tethyan, Upper Permian-Lower Triassic succession located
Methanol is the second most abundant volatile organic compound in the troposphere and plays a significant role in atmospheric chemistry. While there is consensus about the dominant role of living plants as the major source and the reaction with OH as the major sink of methanol, global methanol budgets diverge considerably in terms of source/sink estimates, reflecting uncertainties in the approache
Studies have found that the cognitive model of worry developed by Dugas, Gagnon, Ladouceur and Freeston (1998) involving Intolerance of Uncertainly (IU), Cognitive Avoidance (CA), Positive Beliefs about Worry (PB), and Negative Problem Orientation (NPO) accounts for approximately 40-50% of the variance in worry frequency in adults. A recent trial of the treatment based on this model (Dugas, Brillo
It is predicted that novel nanometer-sized structures incorporating nanoparticles will have a considerable impact on our lives during the coming decades. Engineered nanoparticles are already found in a number of commercially available products. However, many applications of these nanoparticles have only reached the stage of promising ideas or research demonstrations. The number of nanoparticle-bas
Lean blowout (LBO) is one of the major instability problems of premixed combustion. LBO equivalence ratio is a function of inlet temperature and pressure, mass flow or aerodynamic loading, and fuel composition. All these, except the last, vary during startup and with load. Developing gas turbine combustors capable of operating within wider range of fuel compositions requires extensive knowledge ab
In this paper we present a new method to electrodeposit highly porous gold (h-PG) onto a polycrystalline solid gold electrode without any template. The electrodeposition is carried out by first cycling the electrode potential between +0.8 and 0 V in 10 mM HAuCl4 with 2.5 M NH4Cl and then applying a negative potential for the production of hydrogen bubbles at the electrode surface. After that the m
The purpose of this study is to let a group of addicted mothers who live separated from their children voice their thoughts and experiences through in-depth interviews made in the early 90's. From a perspective of experience of life we look at their living conditions, their everyday life, their experiences of pregnancy, their life with the children, and their life after the separation. What does i
Context. Tidal orbital decay is suspected to occur for hot Jupiters in particular, with the only observationally confirmed case of this being WASP-12 b. By examining this effect, information on the properties of the host star can be obtained using the so-called stellar modified tidal quality factor Q′∗, which describes the efficiency with which the kinetic energy of the planet is dissipated within
Rethinking Water-Land Relations through Sustainability Communication. Acqua alta describes the phenomenon of high tide which commonly submerges part of city of Venice during the winter season. In recent years, due to climate change, exceptional high tide levels have been registered, posing considerate challenges to the city’s survival. In an attempt to prevent Venice from being submerged, a majest
How does the brain transform the 2-D light arrays in our eyes into a meaningful 3-D description of surfaces around us? What assumptions does the visual system make about the world when information is incomplete? And how are these assumptions computationally expressed in this perceptual reconstruction process? These questions, and other aspects of binocular depth perception are analysed from a theo
Popular Abstract in Swedish Avhandlingen, som består av tre delar, handlar om olika metoder för att undersöka algebraiska begrepp med hjälp av datorberäkningar. I första delen visar vi att en viss Liealgebra inte, till skillnad från många andra Liealgebror av liknande typ, kan brytas ned i vinkelräta komponenter av en speciellt enkel typ. Andra delen handlar om vilka polynom som kan bildas genomThis thesis consists of a collection of articles all using and/or developing algorithmic methods for the investigation of different algebraic structures. Part A concerns orthogonal decompositions of simple Lie algebras. The main result of this part is that the symplectic Lie algebra C3 has no orthogonal decomposition of so called monomial type. This was achieved by developing an algorithm for fin
The aim of this thesis is to examine the relationship between writing and alterity in three recent novels written by J. M. G. Le Clézio, Désert (1980), Onitsha (1991) and La quarantaine (1995), which deal with the encounter between the so-called primitive cultures and Western society. The first chapter contains a more general discussion on the discourse of alterity in literature and the French exo
In companies that constantly develop new software releases for large markets, there continually arrive new requirements, written in natural language that may affect the development work. Before any decision is made about the requirements, these must be analysed and understood, and related to the current set of implemented and queued requirements. This task is time-consuming owing to the high inflo
Popular Abstract in Swedish Resenärernas värderingar av kvalitet i lokal kollektivtrafik – hur man kan mäta dem, hur de varierar och hur man kan använda dem i planeringen Syftet med arbetet har varit att ta fram ett mer detaljerat underlag för planering av lokal kollektivtrafik. Med mer kunskap om hur olika grupper av resenärer värderar olika delar av en kollektivtrafikresa kan kollektivtrafiknätThe aim of this work was to get a more detailed basis for planning of local public transport. With more knowledge of how segments of travellers assess different parts of a journey, bus routes can be planned to fit either all passengers or selected groups better. It will also be possible to evaluate perceived travel utility separately for each category of passengers. Stated Preference questionnaire
We analysed Mg/Ca, Sr/Ca and Ca isotope ratios of benthonic foraminifers from sediment core tops retrieved during several research cruises in the Atlantic Ocean, in order to improve the understanding of isotope fractionation and element partitioning resulting from biomineralisation processes and changes in ambient conditions. Species include foraminifers secreting tests composed of hyaline low mag
Aim To understand the role and significance of the reindeer, Rangifer tarandus (Linnaeus, 1758), as a specific indicator in terms of late Quaternary biogeography and to determine the effects of global climate change on its range and local extinction dynamics at the end of the Ice Age. Location Late Pleistocene/early Holocene range of reindeer over all of central and western Europe, including south
Migraine attacks occur spontaneously in those who suffer from the condition, but migraine-like attacks can also be induced artificially by a number of substances. Previously published evidence makes the meninges a likely source of migraine related pain. This article investigates the effect of several vasodilators on meningeal arteries in order to find a connection between the effect of a substance
The dissertltion is a cultural-historical analysis of the feast of the Lord of May in a complex and socially conditioned setting. The method follows that of the historically oriented ethnology of the Munich school. As regards theory, I have been inspired by the civilization theory of Norbert Elias and by Robert Darnton's studies of groups of actors and their strategies. I have also found support i
The propositions in this chapter are to a large extent drawn from the thesis Metaphors and norms – understanding copyright law in a digital society (Larsson 2011b), however with some important complements, not least concerning the implications of categorisation. The chapter is explorative in bringing findings from cognitive linguistics into the quite common socio-legal task of studying norms. Its
