Since the Industrial Revolution, human activities have elevated atmospheric CO2 concentrations. The consequences of this include rising temperatures, shifts in precipitation patterns, and increased intensity and frequency of extreme weather events, such as heat waves and droughts. Elevated temperatures can accelerate microbial activity in soil, potentially resulting in an increased rate of soil or
In this study we quantify the partitioning of recent assimilates to above- and below-ground carbon (C) pools in two subarctic mire ecosystems - wet minerotrophic and semiwet ombrotrophic mire - using in situ C-14 pulse-labelling. Ecosystem C partitioning to rhizomes, coarse roots, fine roots, dissolved organic carbon (DOC) and microbes were quantified twice during the growing season at three diffe
There is a need for further studies to compare the decomposition of biochar to that of the original feedstock and determine how these amendments affect the cycling of native organic matter (NOM) of different soils to improve our understanding of the resulting net C sequestration potential. A 510-days incubation experiment was conducted (i) to investigate the evolution of CO2 from soils amended wit
Shelf and coastal regions are exceptionally important for many countries as they provide the main habitat for many economically important fish and shellfish species. With ongoing climate change and human-induced eutrophication the shelf regions are especially affected, resulting in increased temperatures and stratification as well as oxygen depletion of the bottom waters. In order to be able to pr
The Transfermium Working Group (TWG) was set up in 1986 under the joint auspices of the International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Pure and Applied Physics (IUPAP). Its conclusions, duly endorsed by IUPAC and IUPAP, were published in the following three reports: 1.

Land-use changes have been shown to have large effects on climate and biogeochemical cycles, but so far most studies have focused on the effects of conversion of natural vegetation to croplands and pastures. By contrast, relatively little is known about the long-term influence of past agriculture on vegetation regrowth and carbon sequestration following land abandonment. We used the LPJ-GUESS dyna
BACKGROUND:There are limited data on the treatment outcomes of adolescents living with HIV. Our objective was to compare mortality and loss to follow up (LTFU) rates between adolescent and younger age groups at enrollment in care.METHODS:This was a retrospective cohort study carried out in eight health facilities in two regions of Ethiopia. Adolescents (age 10-14 and 15-19 year) and children (age BackgroundThere are limited data on the treatment outcomes of adolescents living with HIV.

During the past few decades, the Swedish spatial planning system has experienced numerous problems and challenges. In particular, there have been changes in legislation and an increased neoliberalisation of planning that gives private actors a larger influence over the planning processes in Sweden. In this article, we analyse these changes through the lenses of collaborative and neoliberal planninDuring the past few decades, the Swedish spatial planning system has experienced numerous problems and challenges.

The identification of causal links between microbial community structure and ecosystem functions are required for a mechanistic understanding of ecosystem responses to environmental change. One of the most influential factors affecting plants and microbial communities in soil in managed ecosystems is the current land-use. In forestry, wood ash has been proposed as a liming agent and a fertilizer,
Evading predators is a fundamental aspect of the ecology and evolution of all prey animals. In studying the influence of prey traits on predation risk, previous researchers have shown that crypsis reduces attack rates on resting prey, predation risk increases with increased prey activity, and rapid locomotion reduces attack rates and increases chances of surviving predator attacks. However, eviden
Surtsey island was formed in a volcanic eruption south of Iceland in 1963 – 1967 and has since then been protected and monitored by scientists. It is the youngest island in the Vestmannaeyjar archipelago. The archipelago is of volcanic origin, but the other islands are ca. 5 000 to 40 000 yrs old. The first two moss species were found on Surtsey as early as 1967 and several new bryophyte species w
Climate change is expected to alter the frequency and intensity of soil drying-rewetting (D/RW) and freezing-thawing (F/TW) events, with consequences for the activities of microorganisms. Although both D/RW and F/TW events cause respiration pulses from soil to the atmosphere, it remains unknown whether the underlying microbial control is similar. Recent work has revealed that soil microbial respon
Den här uppsatsen handlar om preventivt självförsvar och huruvida detta är tillåtet enligt folkrätten, särskilt med utgångspunkt i FN-stadgan. Preventivt självförsvar kan förklaras som rätten att slå till mot en fiende som planerar att angripa en själv, innan denna fiende hunnit genomföra sin attack. Idén om preventivt självförsvar inom folkrätt är inget nytt, ledare över hela världen har genom ti
This thesis consists of two parts. In the rst part, the iterative data-adaptive BIAA spectral estimation technique was extended to estimate lateral blood velocities using ultrasound scanners. The BIAA method makes no assumption on samples depth or sampling pattern, and therefore allows for transmission in duplex mode imaging. The technique was examined on a realistic Field II simulation data set,
Klimatkompensation genom skogsplantering i Globala Syd har blivit ett allt mer vanligt sätt för företag att åtgärda sina växthusgasutsläpp, och därigenom sälja produkter och tjänster med netto noll utsläpp. I Sverige går snabbmatsrestaurangen MAX Burgers AB ett steg längre. De kompenserar 10 % mer än vad de släpper ut genom carbon dioxide removal (CDR), och hävdar därför att de har en "klimat
In recent years, low-cost flights to smaller cities in Central and Eastern Europe grew fast. This growth offered tourists new possibilities to explore new, lesser-known destinations at a low price. At the same time, urban tourism is a common strategy for urban regeneration and development in Central and Eastern Europe, and therefore, a significant factor of the economic restructuring of Post-Socia
Topologioptimering är ett populärt och effektivt verktyg för att hitta smarta designer utformade för att fungera optimalt. Det aktuella forksningsarbetet presenterar en metod för att kunna optimera strukturer som utsätts för varierande laster där det inte är uppenbart var, eller när de högsta spänningarna kommer uppstå. Detta innebär att robusta strukturer smidigt kan genereras som kommer hålla föStress is a key component for structural designs in a variety of applications. The aim of this work is to obtain mechanical structures that are free of stress concentrations. A common ap- proach is to optimize a structure with respect to a specific load case. However, if the structure is subjected to other load cases than the one it has been optimized for, it may not withstand those loads. Also, i
This bachelor's thesis examines how narratives about queer and/or norm-critical performance strategies can counteract the reproduction of stage stereotypes and preconceived normative role interpretations on the independent theatre stages in Sweden. Based on three dyadic interviews with three different independent theatre groups in Sweden, I have analyzed narratives about queer and norm-critica
