We used eddy-covariance (EC) measurements of net ecosystem exchange (NEE) above canopy to assess the effects of thinning on CO2 fluxes at the ICOS Sweden site Norunda in central Sweden. This forest site consists of mixed pine and spruce stands approx. 100 years old. The thinning during late autumn 2008, performed in a semicircle from the mast extending 200m outwards harvested about 25% of the voluWe used eddy-covariance (EC) measurements of net ecosystem exchange (NEE) above canopy to assess the effects of thinning on CO2 fluxes at the ICOS Sweden site Norunda in central Sweden.

Intracellular aggregates of superoxide dismutase 1 (SOD1) are associated with amyotrophic lateral sclerosis. In vivo, aggregation occurs in a complex and dense molecular environment with chemically heterogeneous surfaces. To investigate how SOD1 fibril formation is affected by surfaces, we used an in vitro model system enabling us to vary the molecular features of both SOD1 and the surfaces, as we

Popular Abstract in English Climate migration has become an iconic topic in international climate politics and policy. This work, combining political ecology, critical security studies and post-foundational theories, traces the changes of conflicting discourses across time and space, and assesses the different forms of security they interpellate. While initially attracting attention as a securityThis work seeks to de-naturalise climate-induced migration (CM). Combining political ecology and post-foundational theories, I read CM as a construct that reifies a series of phenomena into an issue to be researched and governed. By assessing the narratives, the knowledge, the logics and imaginaries on which conflicting discourses are built, I analyse the strategies of government they envision. I

Abstract [Bryophyes in base-rich fens in Skåne, southern-most Sweden, now and in the past] Over the last centuries, due to the combined effects of drainage, cultivation, eutrophication and overgrowth, the majority of all tree-less base-rich fens that were once found in Skåne have been lost and the typical species of these habitats have suffered accordingly. Here, the past and present distribution Abstract [Bryophyes in base-rich fens in Skåne, southern-most Sweden, now and in the past] Over the last centuries, due to the combined effects of drainage, cultivation, eutrophication and overgrowth, the majority of all tree-less base-rich fens that were once found in Skåne have been lost and the typical species of these habitats have suffered accordingly.

We describe and compare how methods based on the classicalRice’s formula for the expected number, and higher moments, of level crossingsby a Gaussian process stand up to contemporary numerical methods toaccurately deal with crossing related characteristics of the sample paths.We illustrate the relative merits in accuracy and computing time of the Ricemoment methods and the exact numerical method, We describe and compare how methods based on the classical Rice’s formula for the expected number, and higher moments, of level crossings by a Gaussian process stand up to contemporary numerical methods to accurately deal with crossing related characteristics of the sample paths.We illustrate the relative merits in accuracy and computing time of the Rice moment methods and the exact numerical meth

Background: Few tools evaluates quality of movements in individuals with knee osteoarthritis (OA). The Test for Substitution Patterns (TSP) is developed to measure the ability to perform five functional movements regarding postural control and altered movement patterns (1). TSP is validated and reliable in individuals with anterior cruciate ligament injury, but has not yet been evaluated in indivi

Moth wings are densely covered by wing scales that are assumed to specifically function to camouflage nocturnally active species during day time. Generally, moth wing scales are built according to the basic lepidopteran Bauplan, where the upper lamina consists of an array of parallel ridges and the lower lamina is a thin plane. The lower lamina hence acts as a thin film reflector having distinct reflec

Proteins are dynamic entities that intermittently depart from their ground-state structures and undergo conformational transitions as a critical part of their functions. Central to understanding such transitions are the structural rearrangements along the connecting pathway, where the transition state plays a special role.

The statistical sparse jump model, a recently developed, robust and interpretable regime-switching model, is used to analyze the factors driving the return dynamics of the largest cryptocurrencies. This method simultaneously incorporates feature selection, parameter estimation, and state classification. A wide range of candidate features is considered, including cryptocurrency, sentiment, and fina

Concepts are an important element of the way international lawyers think and talk about international law. They materialise as conceptual terms, such as ‘jurisdiction’, ‘self-defence’ and ‘abuse of rights’. To enable a critical evaluation of international law and legal discourse, it is important that single instances of use of such terms be fully understood. This task presupposes a full recognitio

How does violent conflict affect the spread of Covid-19? In this paper we analyze how violent conflict influences the adoption of preventative measures and infection rate in a very poor, conflict-affected country, Burkina Faso. We use a unique panel of 1,919 households surveyed during the first six months of the Covid-19 pandemic in 2020 and merge these data with indicators of violence at the muniHow does violent conflict affect the spread of Covid-19?

Popular Abstract in Swedish Stora framsteg har gjort det möjligt att, med dagens teknik, inte bara visualisera enskilda atomer, utan även utföra olika typer av operationer och manipulationer på atomskalan med stor precision rent experimentellt. Detta har möjliggjort tillverkning av komplexa nanostrukturer genom montering av komponenter av nanostorlek till större sammansatta system, vilket i sin tuNanowires constitute one of the fundamental building blocks in assembled nanodevices. Due to the high surface to volume ratio, the fraction of surface atoms is not negligible for nanosized elements. Because of the reduced coordination of surface atoms, the physical properties deviate from those of the bulk, which influences the overall physical properties of nanostructures. Consequently, this prov

This thesis examines the impact of monetary policy on demand- and supply-driven inflation in Sweden between 2000 and 2024. The study extends Shapiro’s (2024) decomposition framework using a Bayesian Vector Autoregression with Time-Varying Parameters (BVAR-TVP) to decompose Swedish inflation into demand- and supply-side components. A subsequent regression analysis evaluates the effects of the Riksb

This study aims to scrutinise Serbia’s adaptation to the Copenhagen criteria between 2017 and 2024, by examining the country’s progress and challenges in its path toward EU membership. By using Andrew Moravcsik’s Liberal Intergovernmentalism as the theoretical framework, the research analyses how domestic political preferences, institutional dynamics and international bargaining have shaped Serbia

Chile’s exposure to multiple natural hazards and its fragmented resilience governance highlight the urgent need for a standardised measurement tool. This thesis adapts an Australian framework to develop the Resiliencia Sistémica, Integral, Social y Territorial para Emergencias (RESISTE), a top-down, indicator-based framework rooted in socio-ecological system thinking and tailored to Chile’s contex

This project is a study that has described what condition based maintenance is and has examined the possibilities with condition based maintenance on the new A26 submarine. It finishes with a detailed case study of how a condition based maintenance system could look like on the submarine’s diesel engines. Questions that have been answered are; what is condition based maintenance and how does it wo
