Decomposition of soil organic matter (SOM) in permafrost terrain and the production of greenhouse gases is a key factor for understanding climate change-carbon feedbacks. Previous studies have shown that SOM decomposition is mostly controlled by soil temperature, soil moisture, and carbon-nitrogen ratio (C:N). However, focus has generally been on site-specific processes and little is known about v

The carbon cycle of the terrestrial biosphere plays a vital role in controlling the global carbon balance and, consequently, climate change. Reliably modeled CO2 fluxes between the terrestrial biosphere and the atmosphere are necessary in projections of policy strategies aiming at constraining carbon emissions and of future climate change. In this study, SMOS (Soil Moisture and Ocean Salinity) L3

Little is known about the variation within and among species of long-distance migrants in behavioural strategies and habitat choice on their non-breeding grounds. We report results from regular ringing operations carried out during the winter seasons 2009–2013 and transect counts in 2013, 2015 and 2016 in the Sudan Savanna Zone in Ghana. The best supported capture–mark–recapture model included spe

CD83 is one of the best-known surface markers for fully mature dendritic cells (mature DCs), and its cell-type- and maturation-specific regulation makes the CD83 promoter an interesting tool for the genetic modulation of DCs. To determine the mechanisms regulating this DC- and maturation-specific CD83 expression, chromatin immunoprecipitation (ChIP)-on-chip microarray, biocomputational, reporter,

The Hans Tausen drill site was requested to be on a local dome, as high as possible, with a simple flow pattern and with an undisturbed flow pattern even close to bedrock. The first mapping of the surface elevation was performed as part of a general mapping of the elevation and gravity over Greenland. Later, NASA performed a few overflights of the ice cap. Combining the passes, it was possible to

Background: Most commonly, volume measurements are used to evaluate the effect of lymphedema treatment, but as the accumulation of lymph fluid can be local, this method may not always be the best. Tissue dielectric constant (TDC) can be applied to identify local lymphedema changes, but has not been used before when evaluating treatment in mild arm lymphedema. Thus, the overall aim of this study wa

This work assesses the ability of transradial amputees to discriminate multi-site tactile stimuli in sensory discrimination tasks. It compares different sensory feedback modalities using an artificial hand prosthesis in: 1) a modality matched paradigm where pressure recorded on the five fingertips of the hand was fed back as pressure stimulation on five target points on the residual limb; and 2) a

We have estimated the activation energy for aromatic oxidation by compound I in cytochrome P450 for a diverse set of 17 substrates using state-of-the-art density functional theory (B3LYP) with large basis sets. The activation energies vary from 60 to 87 kJ/mol. We then test if these results can be reproduced by computationally less demanding methods. The best methods (a B3LYP calculation of the ac

The performance of three different backpack-mounted γ-radiation survey systems has been investigated. The systems are based on a LaBr3:Ce detector and a NaI(Tl) detector both with active volume dimensions of 76.2 mm in diameter and 76.2 mm length and a 123% relative efficiency HPGe detector. The detection limits of the systems were tested in a controlled outdoor environment in Sweden, followed by

I had the opportunity to work with the flood plain community: Nossa Senhora das Gracas in the Amazon in Brazil. During a month long stay I observed the daily life of the people. A life where the inhabitants shape their daily routines after the rising and dropping Solemoes river. Solemoes is a part of the Amazon river. I identified a need of harvesting water during the low water season, when the r

Atmospheric new particle formation (NPF) is an important phenomenon in terms of global particle number concentrations. Here we investigated the frequency of NPF, formation rates of 10 nm particles, and growth rates in the size range of 10–25 nm using at least 1 year of aerosol number size-distribution observations at 36 different locations around the world. The majo

Soil and groundwater contamination is an increasingly recognised threat to public health and the environment around the globe. New types of contaminants continue to emerge, and awareness of their threat, continues to develop. Many countries have national clean-up programs with priority lists of the most hazardous contaminated sites. Investigation and remediation of these sites, however, take a lon

Popular Abstract in Swedish Den här avhandlingen har behandlingsresultaten av permanent djupelektrod stimulering i hjärnan (Deep Brain Stimulation, DBS) undersökts ur såväl symptomminsknings som patients och närståendes perspektiv. DBS behandling innebär att en elektrod med fyra poler opereras in i hjärnan genom ett litet hål i skallbenet, och den kopplas till pulsgivardosa. Hela systemet är doltThe treatment related effects and personalized goal fulfilment of Deep Brain Stimulation (DBS) have been assessed in studies with different designs. The brain targets included the thalamus for medically intractable tremor in Parkinson's disease (PD) or essential tremor (ET) and the subthalamicus for reducing hypo-, bradykinesia, tremor, rigidity and dystonia in PD. A Swedish multi-center study sh

Användandet av s.k. kodifikationer som lagstiftningsmodell växte i popularitet som tydligast från och med upplysningstiden. Kodifikationen ämnar ge en fullständig, systematisk och tydlig bild av lagen. Modellen användes av flertalet framväxande nationalstater i 1800-talets Europa, där kodifikationen förstärkte och legitimerade centralstyret. I Sverige uppmärksammades behovet av en reformerad civilThe usage of the legislative model codification grew in popularity from the enlightenment on. The codification aims to present a complete, clear and systematic view of the law. The model was used by several emerging national states in 19th century Europe, where the codification was used to strengthen and legitimize the central power. In Sweden, the pressing need for a reformed civil law was recogn

1977 avkriminaliserades fylleri på allmän plats i svensk rätt. Brottet har sina anor i kungliga förordningar från 1700-talet. Från början klassificerades förseelsen som ett sedlighetsbrott och sedan som ett brott mot den allmänna ordningen. Brottet var förenat med böter och den som påträffades berusad på allmän plats kunde bli föremål för omhändertagande av ordningsmakten. Runt förra sekelskiftet In 1977, drunkenness in public spaces was decriminalized in Swedish law. The crime had its roots in royal decrees from the 18th century. The crime was first categorized in the former penalty law as an offense against decency but became later reclassified as a crime against the public order. The punishment was a fine and a person that was intoxicated in public spaces could be arrested and placed in

In the scientific domain of high energy physics (HEP), the Worldwide LHC Computing Grid (WLCG) was created in order to handle the huge compute and storage needs of the experiments at Large Hadron Collider (LHC). Today WLCG combines about 1.4 million computer cores and 1.5 exabytes of storage from over 170 sites in 42 countries. What ties the sites together is the middleware installed at each site,

År 2019 skedde en revidering av 12 kap. JB, även kallad hyreslagen. Genom lagändringen infördes nya regler för att råda bot på ett antal problem på hyresbostadsmarknaden. Ett av de problem som lagändringen syftat till att åtgärda var oskäliga hyror på andrahandshyresmarknaden, och en ny referensram för vad som utgör en skälig andrahandshyra infördes. Bestämmelsen har formen av en takregel, och staIn 2019 there was a revision of the rental legislation in Chapter 12 of the Swedish Land Code. The amendment introduced new rules to solve several problems in the rental housing market. One of the main problems addressed were unreasonable rent levels in the sublease market, and a new rule was introduced to solve this problem. The rule is a reference framework for what constitutes a legal, acceptab

A strategy for generating potential galectin inhibitors was devised based on derivatization at the C-3′ atom in 3′-amino-N-acetyllactosamine by using structural knowledge of the galectin carbohydrate recognition site. A collection of 12 compounds was prepared by N-acylations or N-sulfonylations. Hydrophobic tagging of the O-3 atom in the N-acetylglucosamine residue with a stearic ester allowed rap

The bone material from three archaeological occupation phases at Huseby Klev provides the best source of evidence currently available about the subsistence strategies of pioneer settlers in Northern Europe. The results from Huseby Klev indicate that the pioneer settlers initially relied heavily on marine mammals for their sustenance. This subsistence strategy changed during the second and third oc
