In the Subantarctic Zone of the Southern Ocean, a combination of physical forcings, chemical solubility and biological fixation is controlling the carbon uptake and thus the role the Southern Ocean is playing in the remediation of global climate change. Therefore, it is necessary to understand the mechanisms controlling oceanic carbon budgets and to quantify biological uptake rates to make reliabl
Buying less and making instead - through upcycling, creating and repairing things - is the motto of the Instagram account make smthng, a Greenpeace campaign focussing on political consumption to deal with the environmental crisis we are in today. With climate change being one of the most pressing issues of our time, finding effective ways of communicating a more sustainable lifestyle is a very imp
We have studied the influence of three different fullerene derivatives on the charge generation and recombination dynamics of polymer/fullerene bulk heterojunction (BHJ) solar cell blends. Charge generation in APFO3/[70]PCBM and APFO3/[60]PCBM is very similar and somewhat slower than charge generation in APFO3/[70]BTPF. This difference qualitatively matches the trend in free energy change of elect
Over the past half-century, drastically increased chemical fertilizers have entered agricultural ecosystems to promote crop production on the Yangtze Plain, potentially enhancing agricultural nutrient sources for eutrophication in freshwater ecosystems. However, long-term trends of nitrogen dynamics in terrestrial ecosystems and their impacts on eutrophication changes in this region remain poorly

Identifying optimal inspection and repair strategies for offshore jacket structures is a challenging task. We present an approach, which is based on recent developments in the field of risk-based operation and maintenance planning at the structural system level. The approach utilizes heuristics to define inspection and repair strategies at the system level and to reduce the search space of possibl
Background: Since its discovery in 2007, the importance of the human gut bacterium Prevotella copri (P. copri) has been widely recognized with its links to diet and health status and potential as next generation probiotic. Therefore, precise, convenient and cost-effective diagnostic tools for the detection and quantification of P. copri from clinical and environmental samples are needed. Results:
OBJECTIVE: To determine the efficacy and safety of low carbohydrate diets (LCDs) and very low carbohydrate diets (VLCDs) for people with type 2 diabetes. DESIGN: Systematic review and meta-analysis. DATA SOURCES: Searches of CENTRAL, Medline, Embase, CINAHL, CAB, and grey literature sources from inception to 25 August 2020. STUDY SELECTION: Randomized clinical trials evaluating LCDs (<130 g/day or
We investigate the population of high-redshift (3≤z < 6) active galactic nuclei (AGN) selected in the two deepest X-ray surveys, the 7 Ms Chandra Deep Field-South and 2 Ms Chandra Deep Field-North. Their outstanding sensitivity and spectral characterization of faint sources allow us to focus on the sub-L* regime (logLX ≲ 44), poorly sampled by previous works using shallower data, and the obscured
Promoting repair of electronics is an important strategy to slow material loops, particularly of critical raw materials, as part of a transition to a circular economy. This contribution accounts for a case study of southern Sweden conducted in order to examine drivers and barriers for repairing electronics, as well as better understand the roles of different stakeholders. Repair activities in the
The Dalton Project provides a uniform platform access to the underlying full-fledged quantum chemistry codes Dalton and LSDalton as well as the PyFraME package for automatized fragmentation and parameterization of complex molecular environments. The platform is written in Python and defines a means for library communication and interaction. Intermediate data such as integrals are exposed to the pl
Population ageing places pressure on pensions and health/caring services, creating an imperative to extend working lives. Alongside this, there has been increased political emphasis in Europe and elsewhere on the provision of care in the home. Many older people will thus be challenged by the responsibilities of caring for the sick, disabled and elderly, and participating in labor market activities
In 2010 the Mozilla Foundation established the Digital Open Badges concept as a virtual incarnation of physical counterparts such as a paper certificate or a youth organisation merit badge. Digital Open Badges offer embedded, verifiable, metadata containing information such as the issuer and award criteria. Open Badges can be used to reward learning, participation or achievement. They can be store
ATT PLÖJA MYCKET, LITE ELLER INGET ALLS Vi blir fler och fler människor på vår planet, och år 2050 beräknas vi vara så många som 10 miljarder. Det innebär att vi måste kunna producera mer mat på en lika stor eller till och med mindre yta jämfört med idag. En stor del av den mat vi konsumerar produceras antingen direkt eller indirekt på åkrar runt om i världen. För lantbrukare som är inriktade på vSoil microorganisms are important for climate regulation as well as for plant nutrition. In agricultural soils the microorganisms are affected by management choices, like which type of tillage that is used. Moldboard plowing, the most common tillage practice, increases mineralization which leads to soil organic carbon (SOC) loss, and may thus reduce soil quality. Conservation tillage practices inf
The mortality decline that started in the eighteenth century led toan unprecedented rise in life expectancy in Europe and other partsof the world. The Swedish mortality decline, starting in the earlynineteenth century, had a distinct delay in urban areas andoccurred simultaneously as a sharp increase in the share ofurban population. Despite the importance of the mortality declinefor modern economi
Denna avhandling undersöker vetenskapens roll i den politiska processens tidiga stadier. Detta görs genom att studera hur "geoengineering" kommer upp på den politiska agendan. Begreppet ”geoengineering” används även på svenska och beskriver en uppsättning idéer om hur man stabiliserar den globala temperaturen genom att ingripa i jordens miljösystem. Begreppet mötte stark skepsis i det vetenskapligThis thesis examines the role of science in the earliest stages of the political process. It does this by studying the emergence of ‘geoengineering’ on the political agenda. The term describes a set of ideas on how to stabilize global temperature by intervening into the Earth’s natural systems, and was subject to a strong taboo in the scientific community until the mid-2000s. Yet within a decade,
