Naturbetesmarker och slåtterängar är bland de mest artrika miljöerna i det svenska jordbrukslandskapet och har därför en avgörande betydelse för bevarandet av biologisk mångfald. För att uppfylla kraven i EU:s Naturrestaureringsförordning och de nationella miljökvalitetsmålen krävs att Sverige både bevarar befintliga gräsmarker med höga naturvärden och restaurerar betydande arealer så att de erhål

ObjectivesPeople with serious illness approaching end of life often end up in emergency and hospital care, frequently against expressed preferences. Consequently, oncology trials record care days as a measure of treatment burden called “time toxicity.” However, this measure ignores the diminishing marginal utility of time: that the value of a day is higher when fewer remain. We aimed to incorporat

Iran’s extraterritorial violence constitutes a structural element of state policy, implemented through a coordinated system of intelligence services, diplomatic platforms, proxy militias, and criminal intermediaries. Rooted in revolutionary doctrine and operationalized by institutions such as the Islamic Revolutionary Guard Corps (IRGC) and its external arm, the Quds Force, this apparatus has enab

This master’s thesis explores the impact from the fire investigations by the Swedish Accident Investigation Authority (SHK) on fire safety in Sweden. Through a mapping survey and a qualitative interview study, it is found that it is often difficult to identify clear connections between the investigations’ safety recommendations and real improvements to fire safety, due to long time spans and multi

Background: In a recently discovered microorganism, Halomonas boliviensis, polyhydroxybutyrate production was extensive and in contrast to other PHB producers, contained a set of alleles for the enzymes of this pathway. Also the monomer, (R)-3-hydroxybutyrate (3HB), possesses features that are interesting for commercial production, in particular the synthesis of fine chemicals with chiral specific

Polyhydroxyalkanoates (PHAs), as bio-based plastics, promise a transition from petroleum products to green and sustainable alternatives. However, their commercial production is yet impeded by high production costs. In this study, we assessed synthetic culture in mono and co-culture modes for bacterial PHA production. It was demonstrated that volatile fatty acids (VFAs) derived from food waste and

Wastewater-based surveillance (WBS) allows the analysis of pathogens, chemicals or other biomarkers in wastewater to derive unbiased epidemiological information at population scale. After re-gaining attention during the SARS-CoV-2 pandemic, the field holds promise as a surveillance and early warning system by tracking emerging pathogens with pandemic potential. Expanding the current toolbox of ana

Human adenovirus (HAdV) type F41 has been identified as a possible cause of the non-A-to-E hepatitis outbreak. This study uses wastewater monitoring to track HAdV F40 and F41, supporting clinical investigations and providing insights into the pathogen's role in the outbreak. Given the limited clinical monitoring in Sweden of HAdV-F40/41, this approach also helps estimate the true infection burden

IntroductionSport-related concussion (SRC) is a pressing issue in Para sport, yet biomechanical mechanisms remain poorly understood. Athletes with visual impairment face elevated risks due to sport-specific demands, such as frequent collisions in blind football. This pilot study examined head acceleration responses in blind football players compared with non-disabled football players, and between

The chiral compound (R)-3-hydroxybutyrate (3HB) is naturally produced by many wild type organisms as the monomer for polyhydroxybutyrate (PHB). Both compounds are commercially valuable and co-polymeric polyhydroxyalkanoates have been used e.g., in medical applications for skin grafting and as components in pharmaceuticals. In this paper we investigate cultivation strategies for production of 3HB i

Background: Alcohol use disorder (AUD) and posttraumatic stress disorder (PTSD) are frequently comorbid and are individually associated with increased risk of suicidal behavior. However, whether their comorbidity exacerbates this risk has not been adequately investigated. Methods: Using a Swedish birth cohort (born 1970–1990; N = 799,203–858,983), we employed Aalen’s linear hazards models to evalu

In three empirical studies, we compare one syntactic and one semantic approach to agreement preferences in so-called pancake constructions (pcs) in Swedish, as in Senap är starkt ‘Mustard is strong’.pcs are either substance-denoting, naming an inherent property of the subject, or situation-denoting, naming a property of the subject that is linked to some event. These two types were found to differ

What methods can foster critical and enduring literacies about tech-intensive futures? With the term “critical literacies,” we refer to forms of intervention grounded in critical theory and holding a “better futures” orientation, whether in relation to media, algorithmic, data or AI-based systems. The past decade has witnessed a groundswell of initiatives among practitioners across domainsto impro

This study investigated the efficiency of the treatment processes of wastewater treatment plants (WWTPs) to remove severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and pepper mild mottle virus (PMMoV) from the wastewater and sewage sludge, as well as the influence of the mode of operation on the quality of the treated wastewater. SARS-CoV-2 and PMMoV were detected and quantified at dif

Increased awareness of environmental sustainability with associated strict environmental regulations has incentivized the pursuit of novel materials to replace conventional petroleum-derived plastics. Polyhydroxyalkanoates (PHAs) are appealing intracellular biopolymers and have drawn significant attention as a viable alternative to petrochemical based plastics not only due to their comparable phys

Biotechnologically produced (R)-3-hydroxybutyrate is an interesting pre-cursor for antibiotics, vitamins, and other molecules benefitting from enantioselective production. An often-employed pathway for (R)-3-hydroxybutyrate production in recombinant E. coli consists of three-steps: (1) condensation of two acetyl-CoA molecules to acetoacetyl-CoA, (2) reduction of acetoacetyl-CoA to (R)-3-hydroxybu

Accumulation of acetate is a limiting factor in recombinant production of (R)-3-hydroxybutyrate (3HB) by Escherichia coli in high-cell-density processes. To alleviate this limitation, this study investigated two approaches: (i) deletion of phosphotransacetylase (pta), pyruvate oxidase (poxB), and/or the isocitrate lyase regulator (iclR), known to decrease acetate formation, on bioreactor cultivati

Since the rise of radical geography in the early 1970s, political economy has been crucial in examining the spatial dynamics of capital in economic geography. Marxist and non-Marxist (particularly institutionalist) economic geographers use political economy to challenge non-political economy approaches that ignore the relationship between microeconomic processes and their spatial manifestations an
