Polycyclic aromatic hydrocarbons (PAHs) of molecular mass (MM) 302 Da comprise numerous structural isomers that are of high concern for human health. Because of their multiplicity, low abundance in the environment, and limited availability of authentic standards, their occurrence, composition, and environmental health risk remain not well characterized. Here we extend the characterization of MM 30
Populärvetenskaplig sammanfattning: Under de senaste åren har det varit mycket fokus på biobränsle som ett sätt att reducera konsumtionen av fossila bränslen och utsläppet av växthusgaser. Flytande biobränslen kan blandas med bensin och diesel som ersättning för fossila bränslen i transportsektorn. Blandningar av biobränsle och bensin eller diesel kan användas direkt i omodifierade motorer och detUnder the Kyoto protocol the European Union (EU) has committed itself to reducing its greenhouse gas emissions to 92% of 1990 levels. Carbon sequestered in agriculture is allowed to be countered against emissions to help meet the targets. Biofuels represent an infinite possibility to sequester carbon in agriculture, as they reduce emissions by replacing fossil fuels. The EU has set the target that
Globins are usually associated with oxygen carriage in vertebrates. However, plants also contain similar heme-containing proteins, called phytoglobins (Pgbs). Unlike conventional hemoglobin, these proteins are often linked to nitric oxide metabolism, energy metabolism and redox maintenance under hypoxic and related abiotic and biotic stress conditions. Class I and II non-symbiotic Pgbs (nsPgbs) ha
Den här uppsatsen syftar till att undersöka hur guldpriset påverkas av olika makroekonomiska variabler samt avkastningen på alternativa tillgångar. Studien är gjord ur ett amerikanskt perspektiv och undersöker hur priset på fysiskt guld påverkas av prisindexet Consumer Price Index – All Urban Consumers (CPI-U), BNP-tillväxt, aktieindexet MSCI US Prime Market 750 Index och Treasury bills med tre må
Syfte: Syftet med denna studie är att undersöka vilka faktorer vid företagens börsintroduktioner, på NASDAQ OMX Stockholm och NGM Equity under åren 2001-2008, som påverkar sannolikheten att en efterföljande nyemission inträffar inom en kort tidsperiod (tre år). Metod: Studien är en kvantitativ undersökning där faktorer vid företagens IPO påverkar sannolikheten att en efterföljande SEO inträffar i
Popular Abstract in Swedish Denna avhandling syftar till att ge en översikt över cirka hundra år av europeisk intellektuell historia som lyfter fram nya aspekter av de klassiska tänkarna. Analysen av de fyra filosoferna Thomas Hobbes, John Locke, David Hume och Charles de Montesquieu syftar till att belysa en generell historisk process, nämligen hur den moderna människosynen växer fram i Europa. EThis essay has three main aims. The first one is to give an overview of some hundred years of European intellectual history, bringing out new aspects of the classical thinkers. The analysis of the four philosophers Thomas Hobbes, John Locke, David Hume and Charles de Montesquieu aims at illustrating a general historical process, viz. the emergence of the modern view of man in Europe. After Hobbes,
Tracking techniques are vital for the understanding of the biology and ecology of organisms. While such techniques have provided important information on the movement and migration of large animals, such as mammals and birds, scientific advances in understanding the individual behaviour and interactions of small (mm-scale) organisms have been hampered by constraints, such as the sizes of existing
Theoretical approaches to learning in practice-based jazz improvisation contexts include situated learning and ecological perspectives. This article focuses on how interest-driven, self-sustaining jazz learning activities can be matched against the concepts of stolen knowledge (Brown & Duguid, 1996) and landscape of learning (Bjerstedt, 2014). Based on an extensive interview study with SwedishTheoretical approaches to learning in practice-based jazz improvisation contexts include situated learning and ecological perspectives.

Digitalization has been frequently discussed within Competition Law over the last few years. It is not surprising that digital platforms have received a signif-icant amount of attention of among competition law experts and legislatures since a relatively few companies own the infrastructure needed for other com-panies to participate in the digital markets. The debate over the adequacy of our curre
Populärvetenskaplig sammanfattning Den ökande urbaniseringen värden över och de hälsorisker som identifierats i samband med värmeböljor i städer, har medfört att det urbana klimatet blivit ett allt viktigare forskningsområde. Vindhastighet är en av de viktigaste parametrarna när det gäller att beräkna lokala klimatvariationer och bedöma eventuella hälsorisker. En enkel beräkningsmetod för vind kanWind is a complex phenomenon and a critical factor in assessing climatic conditions and pedestrian comfort within cities. This master’s thesis attempts to quantify and model the relationship between near ground wind speed and urban geometry using two-dimensional raster data and variable selection methods based on Multiple Linear Regression. A simple regression model can be implemented in a Geogra
Aims: Assessment following heart transplantation (HTx) is routinely performed using transthoracic echocardiography. Differences in long-term mortality following HTx related to donor-recipient matching have been reported, but effects of gender on cardiac size and function are not well studied. The aims of this study were to evaluate differences in echocardiographic characteristics of HTx recipients
BACKGROUND: Currently, only a limited number of molecular biomarkers for malignant melanoma exist. This is the case for both diagnosing the disease, staging, and efficiently measuring the response to therapy by tracing the progression of disease development and drug impact. There is a great need to identify novel landmarks of disease progression and alterations.METHODS: Matrix-assisted laser desor
Phagocytosis is relevant for many research fields and is often measured as a functional outcome. However, accurate quantification can be challenging, and many researchers find it difficult to study in a robust manner. There are many ways to measure phagocytosis, but what is often overlooked is the importance of experimental design and how the analysis is planned and performed. Experimental factors
Antibody binding to bacterial surfaces plays a crucial role in immunity, and a key characteristic of this protein-protein interaction is the binding affinity. Determining the affinity of an antibody binding to its antigen is the first step in predicting the function in a physiological environment where other competing protein interactions may be present. Antibody-antigen affinity is often evaluate
Abstract to PLANNORD 2019: Future challenges for Nordic planning
Interfacial structures on the nanoscale are crucial for a wide field of applications ranging from biological membranes in life sciences through organic solar cells and industrial coatings in soft matter to hard matter structures. The latter include thin film coatings and materials such as magnetic nanoparticles and topological structures like magnetic skyrmions. Advancing such application rests on
A major challenge hampering the industrial and biological exploitation of lipases is the self-limiting effect of the lipolytic reaction. Defying sustained attention throughout history, the influence of lipase catalysed lipolysis on the internal structure of thin triglyceride films has proved elusive. An in-depth understanding of the lipolysis process at the triglycerides/aqueous interface will ass
BACKGROUND: Fever is associated with brain injury after cardiac arrest. It is unknown whether fever management with a feedback-controlled device impacts patient-centered outcomes in cardiac arrest patients. This trial aims to investigate fever management with or without a temperature control device after out-of-hospital cardiac arrest. METHODS: The TEMP-CARE trial is part of the 2 × 2 × 2 factoria
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
