Pesticide use in agricultural landscapes creates environmental contamination that is heterogenous in space and time. Mobile organisms, such as bees, are exposed to multiple contamination sources when visiting patches that vary in the amount, timing and toxicity of pesticides used. Yet, environmental risk assessments (ERA) typically fail to consider this heterogeneity, in part because of the comple
Community cohesion is a recent concept in ecology referring to the varying levels of connectivity and integration between populations of different taxonomic or functional groups within ecosystems. Positive cohesion denotes positive interactions such as mutualism or facilitation, while negative cohesion implies negative interactions such as competitive exclusion or a preference for different habita
Sugar beet molasses is a low-value byproduct from the sugar industry. It contains significant amounts of sucrose (approx. 50% (w/w)), which can be used for many different applications, for example, as feedstock for the production of fuel (as ethanol) and biobased chemicals such as 5-hydoxymethyl furfural (HMF). To produce platform chemicals, sucrose is hydrolyzed into its monomeric C6 sugars: gluc
The toxicity of particulate matter (PM) is dependent on particle physical and chemical properties and is commonly studied using in vivo and in vitro approaches. PM to be used for in vivo and in vitro studies is often collected on filters and then extracted from the filter surface using a solvent. During extraction and further PM sample handling, particle properties change, but this is often neglec
Background: Cardiovascular disease (CVD) is a major global health issue, primarily caused by atherosclerosis. Psychological factors may play a role in the development and progression of CVD. However, the relationship between psychological factors and atherosclerosis is complex and poorly understood. This study, therefore, aimed to examine the association of psychological factors with (i) coronary
Svensk byggindustri är under förändring. Stora delar av produktionen läggs idag ut på entreprenad och byggföretag förlitar sig på underentreprenörer i större utsträckning än tidigare. Som en del av en global trend av kostnadsreducering inom byggindustrin, försöker byggföretag minimera antalet anställda hantverkare och istället utkontraktera arbete till underentreprenörer i strävan efter organisatoThe organisation of work in the Swedish building sector is changing due to increased subcontracting and the adoption of construction management. In this study, construction management refers to a specific subcontracting regime, in which contractors externalise all parts of the production process and organise work through subcontractors. Echoing global trends of cost-cutting, this externalisation b
Objectives: In this study, we aimed to assess the stratification ability of the Fracture and Mortality Risk Evaluation (FAME) index for reoperation, new fragility fracture, and mortality during one-year follow-up. Patients and methods: Between November 2018 and July 2019, a total of 94 consecutive hip fragility fracture patients from two centers (20 males, 74 females; mean age: 79.3±8.9 years; ran
Evolutionary ecology aims to better understand how ecologically important traits respond to environmental heterogeneity. Environments vary both naturally and as a result of human activities, and investigations that simultaneously consider how natural and human-induced environmental variation affect diverse trait types grow increasingly important as human activities drive species endangerment. Here
En större mängd kvartsavslag och brända ben, upptäckta vid rekognosering (Norrbottens Museum) av hyggesberedda ytor norr om byn Sammakko, c. 40 km SO Gällivare, har tolkats att indikera ett kortvarigt använt boplatsområde. Platsen, liggande c. 100 meter norr Linaälven och i kanten av en nästan igenväxt göl, genomgick arkeologisk förundersökning sommaren 2019. Insamlat material av brända ben och
It is often a challenge for a child to communicate their pain, and their possibilities to do so should be strengthened in healthcare settings. Digital self-assessment provides a potential solution for person-centered care in pain management and promotes child participation when a child is ill. A child's perception of pain assessment differs when it is assessed using digital or analog formats. As w
Adsorption isotherms taken at temperatures ranging from 20 to 77 K show a large pore volume and surface area of 980 m2 g-1 for the physical adsorption of molecular hydrogen on MCM-41. The adsorbed hydrogen behaves more like a solid than a liquid and isosteric heats of adsorption reveal a heterogenous surface. The evaporation behaviour of the adsorbed hydrogen indicates that the hexagonally packed
När vi människor försöker röra på oss skickas elektriska impulser genom nervsystemet från hjärnan ner till de muskler som är inblandade i den tilltänkta rörelsen. Att kunna mäta sådana nervimpulser hade varit av värde för en rad tillämpningar—information hade då kunnat överföras direkt från nervsystemet utan att gå via långsamma, mekaniska gränssnitt så som tangentbord och pekskärmar. OlyckligtvisElectrical activity produced by muscles during voluntary movement is a reflection of the firing patterns of relevant motor neurons and, by extension, the latent motor intent driving the movement. Once transduced via electromyography (EMG) and converted into digital form, this activity can be processed to provide an estimate of the original motor intent and is as such a feasible basis for non-invas
This doctoral thesis is concerned with agency in the work of a performer, curator, and composer, and how these agencies are socio-culturally constructed. Grounded in creative practice as primary research methodology, the project builds on feedback loops between creation, analysis, and interpretation. The aim is to better understand the conventional norms that define the roles of composer and perfo
Climatic extreme events are expected to occur more frequently in the future, increasing the likelihood of unprecedented climate extremes (UCEs) or record-breaking events. UCEs, such as extreme heatwaves and droughts, substantially affect ecosystem stability and carbon cycling by increasing plant mortality and delaying ecosystem recovery. Quantitative knowledge of such effects is limited due to the
BACKGROUND: Atrial myopathy refers to structural and functional cardiac abnormalities associated with atrial fibrillation and stroke, but appropriate diagnostic criteria are lacking.OBJECTIVES: This study aimed to assess prevalence, clinical correlates, and overlap between potential atrial myopathy markers.METHODS: The population-based SCAPIS (Swedish CArdioPulmonary bioImage Study) prospectively
Globins are usually associated with oxygen carriage in vertebrates. However, plants also contain similar heme-containing proteins, called phytoglobins (Pgbs). Unlike conventional hemoglobin, these proteins are often linked to nitric oxide metabolism, energy metabolism and redox maintenance under hypoxic and related abiotic and biotic stress conditions. Class I and II non-symbiotic Pgbs (nsPgbs) ha
I Sverige överlever idag uppemot 80% av de barnen som är födda extremt för tidigt (födda innan graviditetsvecka 28). Dock medföljer en hög sjuklighet, där uppemot 20% av barnen utvecklar olika sjukdomstillstånd såsom blödning i hjärnas hålrum, även kallat intra-ventrikulär hjärnblödning (IVH). Dessutom löper de extremt för tidigt födda barnen en ökad risk att utveckla en intellektuell och neurologExtremely preterm infants (i.e., born below 28 gestational weeks), are at high risk of developing brain morbidities including intraventricular hemorrhage (IVH) and neurodevelopmental impairment. Despite over 50 years of research, there is currently no effective therapy available for preventing IVH. Insulin-like growth factor 1 (IGF-1) plays a pivotal role in perinatal development. Extremely preter
Jaktturism anses ofta spela en viktig roll i hållbar landsbygdsutveckling. Turismenkan skapa arbeten, samt bidra till att traditioner och miljöer bevaras. En kommersiell jakt som riktar sig till lokala såväl som inresande jägare kan innebära att viltet kan användas som resurs på flera och nya sätt. När jakten ramas in och paketeras som turismprodukt, där boende, måltider och guidning ingår, kan ja
