Three different, state-of-the-art biogeochemical models are adapted in order to quantify the carbon dioxide (CO2), nitrous oxide (N 2O), and methane (CH4) exchanges between arable lands and the atmosphere. Biome-BGC and MOD17 are validated using the long-term measurement results from Hegyhátsál tall tower site (Western Hungary). After a simple bias correction, it was found that Biome-BGC is capabl
The aim of this article is to explore how new industrial paths emerge and grow in peripheral regional economies. Current conceptualizations of regional path development are based on experiences from core regions and fail to provide satisfactory theoretical explanations of new path-creating activities in peripheral areas. Our conceptual approach combines the notions of path development and knowledg
We investigate the star formation-feedback cycle in cosmological galaxy formation simulations, focusing on the progenitors of Milky Way (MW)-sized galaxies. We find that in order to reproduce key properties of the MW progenitors, such as semi-empirically derived star formation histories (SFHs) and the shape of rotation curves, our implementation of star formation and stellar feedback requires (1)
Reactions of 4-thio-2′-deoxyuridine d(s4U) and 4-thiouridine 5′-monophosphate s4UMP with trans-[AuY2Cl2]+/– (Y = CN– or NH3) have been investigated by conventional and high-pressure stopped-flow spectrophotometry in aqueous solution with 2.9 ⩽ pH ⩽ 7.0. For a given combination of metal complex and sulfur donor the observed second-order rate constants decreased with increasing pH. In the pH range 2
BACKGROUND: As many as 88% of heart transplant recipients (HTRs) suffer from psychological distress. Both psychosocial factors and physical health are associated with increased psychological distress. However, the causes and impacts of psychological distress are unclear. HTRs strive for a sense of control over their health and daily lives in order to improve their psychological well-being. Perceiv
Modern working life is characterized by change and competiveness. It is also characterized by a drift away from low-skilled work to more complex jobs and increased social interaction. This means that the human resources employees and their skills, competencies, engagement and motivation are the greatest asset of many organizations. This has implications for how an organization can be healthy, i.e.
The main focus of the work presented in this thesis is on experimental studies oflaser acceleration of protons and other positive ions from solid targets. The topic is explored from three different angles: firstly, the development of diagnostics adapted to the ion pulses, secondly, the characterization of the source of the energetic particles and, finally, the application of laser-accelerated prot
Irradiating a flame via microwave radiation is a plasma-assisted combustion (PAC) technology that can be used to modify the combustion chemical kinetics in order to improve flame stability and to delay lean blow-out. One practical implication is that combustion engines may be able to operate with leaner fuel mixtures and have an improved fuel flexibility capability including biofuels. Furthermore,
According to the waste hierarchy principle, which constitutes the basis of European waste legislation, waste prevention and re-use are considered – most of the times – better waste management options than recycling. However, prevention and re-use activities are difficult to operationalise and measure, without a monitoring framework in place. This contribution investigates the potential of re-using
Ocean Drilling Program (ODP) Site 1051 (Blake Nose, western North Atlantic) is of crucial importance for reconstructing diatom evolution and biosiliceous sedimentation patterns through the early Cenozoic period of extreme greenhouse warmth followed by the progressive global cooling. The magnetostratigraphy in Hole 1051A, however, has been subject to divergent interpretations resulting in multi-mil
Background: The efficacy of cervical cancer screening programs is dependent on the participation rate. To increase participation among women not attending cervical cancer screening, self-collected samples for detection of high-risk human papillomavirus (hr-HPV) may be an option. The aims of this study were: to investigate the response rate to sending a self-collected vaginal sample for hr-HPV mRNA
Monoamines are presumed to be diffuse metabotropic neuromodulators of the topographically and temporally precise ionotropic circuitry which dominates CNS functions. Their malfunction is strongly implicated in motor and cognitive disorders, but their function in behavioral and cognitive processing is scarcely understood. In this paper, the principles of such a monoaminergic function are conceptuali
Recent reports of increasing iron (Fe) concentrations in freshwaters are of concern, given the fundamental role of Fe in biogeochemical processes. Still, little is known about the frequency and geographical distribution of Fe trends or about the underlying drivers. We analyzed temporal trends of Fe concentrations across 340 water bodies distributed over 10 countries in northern Europe and North Am
Material and energy costs represent about 50% of the operating costs incurred by European small and medium-sized enterprises (SMEs). Although the potential for resource efficiency improvements is high, the necessary awareness and human resource capacities to explore this potential are limited. Existing tools for exploration of resource efficiency improvement potentials have several shortcomings: t
The objective of the research presented in this paper was to investigate how different characteristics of whey protein microparticles (MWP) added to milk as fat replacers influence intermolecular interactions occurring with other milk proteins during homogenisation and heating. These interactions are responsible for the formation of heat-induced aggregates that influence the texture and sensory ch
In my presentation I will seek to describe, analyse and reflect on the challenges and opportunities of agroecology in the province of province of Misiones, Northeaster Argentina, and the territorial dynamics generated from the promotion of a particular way to produce and trade food. My focus will be on the discourses and practices around food production for family consumption and for local markets
In a previous study, in order to investigate the effect of charge stratification on combustion behavior such as combustion efficiency and combustion phasing which also largely affects the emissions, an experiment was conducted in a heavy-duty compression ignition (CI) metal engine. The engine behavior and emission characteristics were studied in the transition from HCCI mode to PPC mode by varying
Popular Abstract in Swedish Under 1920-talet och framåt accelererade moderningseringsprocessen på många plan och det svenska samhället kom att allt mer förändras. Följande studie handlar i mycket om hur man på olika sätt kan förhålla sig till den nya tid som kommer. Gertud Lilja var verksam mellan 1924 och 1964. Under 1920-40-talen var hon en känd och diskuterad författare, men med tiden har henneThe aim of this thesis is to present and discuss the author Gertrud Lilja with a special focus on her relationship to modernity from a feminist perspective. In the 1920s Lilja was regarded as an interesting and promising author. Ten years later she was seen as a conservative and popular author who wrote mainly for women. As this is the first published thesis that discusses Gertrud Lilja it focuses
Background: Symptoms associated with primary headaches are linked to cranial vascular activity and to the central nervous system (CNS). Review: The central projections of sensory nerves from three cranial vessels are described in order to further understand pain mechanisms involved in primary headaches. Tracers that label small and large calibre primary afferent fibres revealed similar distributio
Hypothesis: Nitric oxide (NO)-releasing Pluronic F127 hydrogels (F127) containing dissolved S-nitrosothiols or pendant N-diazeniumdiolate (NONOate) groups have been described. The NO charging of these hydrogels is usually limited by their low stability or disruption of the micellar packing. S-nitrosothiol-terminated F127 may emerge as a new strategy for allowing NO delivery at different rates in b
