Biodiversity offsetting (BO) is aimed to counterbalance biodiversity impacts from development projects. In Sweden, interest in BO within urban planning has grown since the mid-to-late 1990s, when the approach was first piloted in the municipality of Lomma. Because urban planning often involves non-protected nature, BO is not legally mandated but instead implemented on a voluntary basis. So far, ev
Passivity arises from spontaneous formation of a thin protective passive film (oxide/hydroxide layer) on the metal surface, and the stability of passive film is of great importance for corrosion resistance. This study investigates the formation, stability, and transpassive dissolution of passive films on two Ni-based alloys, Alloy 625 and Alloy 59, in acidified NaCl solution, by combining in situ
The 1990s were significant for several events promoting environmental protection and the sustainable use of natural resources. For instance, both the United Nations Conference on Environment and Development in 1992, which stressed the need to stop the overconsumption of natural resources and the United Nations Framework Convention on Climate Change endorsed a framework to combat climate change. Si
Access to detailed network data is often constrained by access-controlled datasets or by extensive manual labour. Using aerial imagery and a simplified OpenStreetMap road-level graph, a novel approach is proposed to extract lane-level road topology graphs at signalized intersections based on detection of common road objects, classification of lane attributes, and a simultaneous lane-to-lane connec
The debate about post-2012 global climate governance has been framed largely by proponents and opponents of the policymaking process established by the United Nations Framework Convention on Climate Change (UNFCCC). In light of the proliferation of institutions governing some aspects of climate change, analysts have asked whether a centralized or a polycentric climate governance architecture will
The objective of this study was to identify possible changes in mRNA and protein expression of high-mobility group box protein 1 (HMGB1) and its suggested receptors - receptor for advanced glycation end-products (RAGE) and Toll-like receptor 2 (TLR2) and TLR4 - in human cervix during pregnancy, term and preterm labor. Cervical biopsies were taken from 58 women: 20 at preterm labor, 24 at term labo
The Wilms tumor gene, WT1, encodes a zinc-finger DNA binding protein which is thought to function as a tissue specific transcription factor, regulating cell growth and differentiation. High expression of WT1 has been detected in a range of acute leukemias. To elucidate a role for WT1 in leukemogenesis, we transfected the monoblastic cell line U937, which lacks detectable levels of endogenous WT1,
The scope of this presentation is a new methodology to correct conventional NIR data for scattering effects. The technique aims at measuring the absorption coefficient of the samples rather than the total attenuation, measured by conventional NIR spectroscopy. The main advantage of this is that the absorption coefficient is independent of the path length of the light inside the sample, and therefo
Some leading science programs undertaken with Very Large Telescopes and challenges driving the progress of the Extremely Large Telescopes are discussed together with the corresponding requirements. They concern expolanets, Earth-like planets, habitable zones, formation of stars and galaxies, first stars and cosmology. A description is attempted
This study describes frequencies and associations between eating difficulties, assisted eating and nutritional status in 520 elderly patients in hospital rehabilitation. Eating difficulties were observed during a meal and nutritional status was assessed with Subjective Global Assessment form. Eighty-two percent of patients had one or more eating difficulties, 36% had assisted eating and 46% malnut
The mechanism of atomic and molecular ionization in intense, ultra-short laser fields is a subject which continues to receive considerable attention. An inherent difficulty with techniques involving the tight focus of a laser beam is the continuous distribution of intensities contained within the focus, which can vary over several orders of magnitude. The present study adopts time of flight mass s
The synthesis and characterization of phthalocyaninato-ruthenium (PcRu) complexes with potential functional axial ligands are described. The solubility of these PcRu complexes was much improved compared to their parent phthalocyanines without Ru, enabling purification by normal flash column chromatography and also NMR measurements in common solvents (e. g. DMSO-d(6) and CDCl3). Adsorption of these
Cardiopulmonary diseases are major causes of death worldwide, but currently recommended strategies for diagnosis and prevention may be outdated because of recent changes in risk factor patterns. The Swedish CArdioPulmonarybioImage Study (SCAPIS) combines the use of new imaging technologies, advances in large-scale 'omics' and epidemiological analyses to extensively characterize a Swedish cohort of
TRIM28 is a corepressor that mediates transcriptional silencing by establishing local heterochromatin. Here, we show that deletion of TRIM28 in neural progenitor cells (NPCs) results in high-level expression of two groups of endogenous retroviruses (ERVs): IAP1 and MMERVK10C. We find that NPCs use TRIM28-mediated histone modifications to dynamically regulate transcription and silencing of ERVs, wh
Syftet med denna studie är att analysera hur ungdomar som varit placerade på särskilda ungdomshem upplever, definierar och tolkar ett behandlingsprojekt, som involverade olika myndigheter, benämnt Motverka Våld och Gäng. Dessutom uppmärksammas hur de tolkade de i projektet anställda samordnarna. Den personliga aspekten i relationen mellan ungdomar och samordnare framställs som viktig och det verkThe purpose of this study is to analyse the way young people who were institutionalised in so called special youth-homes experienced, defined and iterpreted on the one hand the project “Motverka Våld och Gäng” (meaning: “Counteract Violence and Gangs”), and on the other hand the Coordinators employed in this project. There is a big variation in the perception of the coordinators. One common deno
Popular Abstract in Swedish See attachment in related materialThe combustion engine is today the dominant technology for transportation of goods and people world-wide. Concerns for global warming, toxic exhaust emissions, as well as cost and availability of fuel have in recent years created incentives for technological evolution of combustion engines. More sophisticated engine instrumentation with additional degrees of freedom has been added to the engine de
Popular Abstract in Swedish En industrirobot är en flexibel programmerbar maskin som bör användas för sådant arbete som inte lämpar sig för människan att utföra. Olika tekniska begränsningar i dagens styrsystem begränsar dock robotars tillämpbarhet. Avhandlingen föreslår ett nytt sätt att bygga upp robotstyrsystem så att roboten på bästa sätt skall kunna tjäna människan.Industrial robots play a key role in manufacturing systems. Robots are distinguished from other types of machinery mainly on the basis of their programmability and ability to be adaptable to different tasks. The use of computer control to achieve desired flexibility implies that software issues for embedded control systems are central for the applicability and utilization of the equipment. The str
Different aspects of hybrid control systems are treated: analysis, simulation, design and implementation. A systematic methodology using extended Lyapunov theory for design of hybrid systems is developed. The methodology is based on conventional control designs in separate regions together with a switching strategy. Dynamics are not well defined if the control design methods lead to fast mode sw
