In terrestrial ecosystems, the largest pool of amorphous silica (ASi) is stored in soils and is an important reservoir of biologically active Si for the global biogeochemical cycling of Si. Only limited data are available that quantify the size of this reservoir and often these estimates are made from the physical separation of silt-sized phytoliths, which can underestimate the ASi pool. Soil samp

Understanding the responses of tundra systems to global change has global implications. Most tundra regions lack sustained environmental monitoring and one of the only ways to document multi-decadal change is to resample historic research sites. The International Polar Year (IPY) provided a unique opportunity for such research through the Back to the Future (BTF) project (IPY project #512). This a

The Advanced GAmma Tracking Array (AGATA) is a European project to develop and operate the next generation gamma-ray spectrometer. AGATA is based on the technique of gamma-ray energy tracking in electrically segmented high-purity germanium crystals. This technique requires the accurate determination of the energy, time and position of every interaction as a gamma ray deposits its energy within the

Open Educational Resources (OER) are teaching, learning and research materials available on the Internet. Resources are open and free, and usually under creative commons licenses (cc). Depending on the licenses resources are allowed to be used, reused, transmitted, and also sold openly and freely. Internationally, the OER movement is very strong. In Sweden, however, the trend towards open publicat

The modular software MOLSIM for all-atom molecular and coarse-grained simulations is presented with focus on the underlying concepts used. The software possesses four unique features: (1) it is an integrated software for molecular dynamic, Monte Carlo, and Brownian dynamics simulations; (2) simulated objects are constructed in a hierarchical fashion representing atoms, rigid molecules and colloids

We have combined experiments with atomic-scale molecular dynamics simulations to consider the influence of ethanol on a variety of lipid membrane properties. We first employed isothermal titration calorimetry together with the solvent-null method to study the partitioning of ethanol molecules into saturated and unsaturated membrane systems. The results show that ethanol partitioning is considerabl

Background: Attention deficit hyperactivity disorder (ADHD) is among the most common psychiatric disorders of childhood that persists into adulthood in the majority of cases. The evidence on persistence poses several difficulties for adult psychiatry considering the lack of expertise for diagnostic assessment, limited treatment options and patient facilities across Europe. Methods: The European Ne

Background: Prevention and treatment of medical issues are the main task of a health service at a youth camp. However, only few reports about organisation and implementation of camp health care are available. This makes it difficult for future camp directors to plan and estimate the health care needed for a certain camp size. We summarize the experience in planning and running health care for the

This essay explores the possible influence from WTO law into Community law in the area of State aid. In order to do so one needs to examine questions relating to material law as well as EC enforcement and procedure. Special attention is paid to State aid as regulated in Article 87.1 ECT. When an EC Member State thinks that another Member State is violating Article 87 ECT by administering illegal a

Kognitiv beteendeterapi (KBT) kan idag erbjuda evidensbaserade behandlingar för de flesta psykiska sjukdomar, men har inte utvecklats systematiskt för svagbegåvade personer med psykiska besvär. Individerna i denna osynliga befolkningsgrupp är emellertid extra sårbara för psykisk ohälsa pga sina sociala livsvillkor, samt sina psykobiologiska förutsättningar. Med stöd i forskning om KBT för lågbegåCognitive-Behavioural-Therapy (CBT) can today offer evidence-based treatments for most psychological disorders, but has not developed systematically for people with borderline intellectual functioning (IQ 70-85) and their psychological disorders. Individuals in this unseen population are, however, exceptionally vulnerable to psychological disorders because of their social life situation, as well a

The aim of the thesis is to analyse the transfer pricing rules in the VAT system, namely Articles 72 and 80 of the Recast VAT directive. The thesis specifically aims to investigate the application of the open market value to improperly valued transactions between related parties, what the open market value in the VAT system is and how it is determined. The second chapter of the thesis presents an

The phase field method emerged as a tool to solve free boundary problems with a sharp interface. In previous methods, this involved the computationally inefficient and complicated tracking of a moving interface. The phase field method overcomes this limitation by introducing an auxiliary variable called the order parameter which varies continuously over the whole domain and takes on finite values

Den 1 januari år 2004 infördes i svensk rätt möjligheten att bilda tredimensionella fastigheter. Detta innebar en stor principiell förändring i svensk fastighetsrätt. Från att som tidigare endast kunna avgränsas i markplanet kan en fastighet nu bestå av en sluten volym, en tredimensionell fastighet. En förutsättning för att bilda en tredimensionell fastighet är att det står klart att åtgärden är January 1, 2004, a new law in Sweden made it possible to form three-dimensional real property units. This was a fundamental change in Swedish real estate law. Before, real property could only be defined in the horizontal plane but can now be defined both horizontally and vertically, making it possible for real property to consist of a closed volume rather than just an area. A prerequisite to form

Även om intentionen att agera fungerar som prediktor till beteende så har den samlade forskningen visat på en svaghet i intentioners kraft att påverka beteenden. Implementationsintentioner har visat sig effektiva för att skapa beteenden i kongruens med intentioner under en rad omständigheter, bland annat för reglering av emotioner. Implementationsintentioner är påståenden i ”Om ... då”- form som bEven though intentions works as predictors for behavior, research has shown a weak relation between the two. Implementation intentions has been shown to be effective in bridging the gap between intention and behavior, under various circumstances, for example when it comes to emotion regulation. Implementation intentions are ”If... then”-plans that connect a situation to a desired behavior. This st

Purpose of Review: Osteoarthritis (OA) is the most common forms of arthritis in the general population, accounting for more pain and functional disability than any other musculoskeletal disease. There are currently no approved disease modifying drugs for OA. In the absence of effective pharmacotherapy, many patients with OA turn to nutritional supplements and nutraceuticals, including collagen der

Alzheimer’s disease affects millions of lives worldwide. This terminal disease is characterized by the formation of amyloid aggregates, so-called amyloid oligomers. These oligomers are composed of β-sheet structures, which are believed to be neurotoxic. However, the actual secondary structure that contributes most to neurotoxicity remains unknown. This lack of knowledge is due to the challenging n

Museomics is a valuable approach that utilizes the diverse biobanks that are natural history museums. The ability to sequence genomes from old specimens has expanded not only the variety of interesting taxa available to study but also the scope of questions that can be investigated in order to further knowledge about biodiversity. Here, we present whole genome sequencing results from the enigmatic

To survive organisms must defend themselves against pathogens. Classical Major Histocompatibility Complex (MHC) genes play a key role in pathogen defense by encoding molecules involved in pathogen recognition. MHC gene diversity influences the variety of pathogens individuals can recognize and respond to and has consequently been a popular genetic marker for disease resistance in ecology and evolu
