Lignocellulosic materials (e.g., straw and bran) are gaining interest as feedstocks for the manufacture of higher value products, recognizing xylooligosaccharides (XOS) as interesting prebiotic compounds, and putting enzymes converting xylooligosaccharides into focus. In this work, we are investigating a XOS converting enzyme from the probiotic bacterium Levilactobacillus brevis (formerly Lactobac
Aims Methadone and buprenorphine diversion by patients in opioid substitution treatment (OST) is a poorly understood phenomenon. We study the norms and attitudes on diversion among OST patients, including the role these norms and attitudes play as diversion risk factors. We also study whether perceived quality of care, social bonds to treatment staff, and deterrence can be associated with diversio
Background: Opioid substitution treatment (OST) with methadone or buprenorphine is the most effective means of treating opioid dependence. If these substances are used by people who are not undergoing OST, they can however carry serious risks. This article examines the lifetime prevalence, motives, and drug sources for such use, as well as geographical differences in these variables. Methods: Stru
Background: Viral infections, including COVID-19, are associated with an increased risk for type 1 diabetes (T1D), but potential underlying mechanisms remain unexplored. We evaluated whether COVID-19 or influenza A infection is characterized by differential DNA methylation at immune and T1D susceptibility genes in young children at risk for T1D. Methods: Epigenome-wide association analysis using t
Gross primary production (GPP) of the vegetation is the largest carbon exchange process of the global carbon cycle. Currently, within satellite-based remote sensing, GPP is generally modelled using linear light use efficiency models where GPP is related to photosynthetically active radiation absorbed by the green vegetation (APAR). These models work well on moderate to low spatiotemporal averaging
The increased demand, driven by a growing population and changing dietary habits, has created immense pressure on agroecosystems throughout the globe. In semi-arid areas, this increased pressure has led to excessive use of agrochemicals in agriculture, which poses a threat of potentially toxic metal (PTM) contamination in agricultural soils. PTMs in agricultural soils result in significant environ
More than 21 million tons of cheese whey are produced annually worldwide, posing an environmental risk if not properly managed. Due to widespread lactose intolerance, cheese whey, which contains lactose, can pose health problems for many individuals. Thus, the management of the cheese whey is necessary to avoid environmental and health problems. This study presents a sustainable approach for whey
Background: A wrist-worn wearable device for acquiring limb and chest ECG leads (wECG) may constitute a promising approach to detection of acute myocardial infarction (AMI). However, it remains to be demonstrated whether the information conveyed by the wECG is sufficient for AMI detection. Objective: To explore explainable machine learning models for detecting AMI using the wECG. Methods: Two type
In recent years, the environmental impact of warfare has made front-page news. Discussions about “ecocide”—a term first proposed in 1970 by Yale biologist Arthur W. Galston to describe the large-scale destruction of ecosystems during the Vietnam War—have come into the spotlight. The preparation and conduct of war, along with the social, economic, and scientific reorganisation that accompany it, of
The Velika Vrbica loess-palaeosol sequence, situated on the south-western bank of the Danube River in northeastern Serbia, represents one of the key Quaternary records in the lower Danube basin, covering the MIS 5-MIS 1 period. Previous investigations of the upper 500 cm established a high-resolution chronology and revealed unexpected patterns of dust accumulation during interstadial phases. In th
Volatile organic compounds (VOCs) include many types of organic compounds, such as alkanes, olefins, aldehydes, etc. They have attracted widespread attention in various fields such as food and flavor analysis, environmental and atmospheric research, safety, or healthcare. Developing efficient, practical, and high-value industrial VOC utilization technologies is crucial for sustainable social and h
Hydrodeoxygenation (HDO) is a catalytic process applied for the reduction of oxygen levels in hydrocarbons from bio-derived feedstock as part of the processing into renewable fuel. The MoS2-based hydrotreating catalysts, currently being applied for the HDO reaction, are exposed to a complex environment consisting of O-rich hydrocarbons and water, which adversely impacts the state and stability of

PowerPoint-presentation 2014-03-12 1 Föreläsning 2 Vad är moral? Om moralfilosofi är ”strävan att på ett systematiskt sätt förstå moralens natur och vad den kräver av oss”, vad är moralfilosofins ”studieobjekt”? Dvs. vad är det moralfilosofer filosoferar om? Det uppenbara svaret är naturligtvis ”moralen”: Men vad är moral för någonting? 2 3 Tyvärr finns det ingen allmänt accepterad definition

Popular Abstract in Swedish Det mesta av det genetiska materialet i en eukaryot cell finns samlat till kärnan och är organiserat i kromosomer. Varje gång en cell delas kopieras kromosomerna så att de båda resulterande cellerna får ett bibehållet kromosomantal. Den mekanism som styr denna replikeringsprocess förmår dock inte kopiera de yttersta kromosomändarna, vilket resulterar i att dessa blir koTelomeres are specialized complexes of DNA and proteins that cap and confer stability to the ends of eukaryotic chromosomes. The telomeric DNA of most eukaryotes is composed of tandemly arranged short repeats. Within the budding yeasts these repeats are diverged in length as well as in nucleotide composition. However, they contain a sequence resembling the consensus binding sequence of the major t
In the aftermath of the nuclear weapons testing and as compared with agriculture, the forest industry has received relatively little attention in spite of its large-scale use of radiocesium- contaminated wood and water. After the Chernobyl nuclear power plant accident in 1986, numerous studies of the forest environment have been conducted with respect to radionuclide transfer through the forest ec
Popular Abstract in Swedish Många växtarter kan inte kolonisera kalkjordar och det är stora skillnader i artsammansättningen mellan kalkjordar och närliggande surare jordar. Detta beteende kallas ofta för kalkskyende och tycks orsakas av en oförmåga hos dessa växtarter att lösa och ta upp fosfat och järn ur kalkjordar. Kalkjordar innehåller mycket låga halter av järn och fosfat löst i marklösninge
This thesis examines the effect of water quality, habitat and species interactions on the occurrence and abundance of stream fishes in southern Sweden. I found that improvements in water quality between the 1960s and 1990s have led to recolonization of streams by brown trout (Salmo trutta L.), stone loach (Barbatula barbatula L.) and eel (Anguilla anguilla L.). The response was greatest for brown
