Variability of antioxidant compounds and capacities in four wild fruits collected in different years and locations in Mozambique

This study investigated the variability of antioxidant compounds and capacity of four wild edible fruits from Mozambique: Adansonia digitata (AD), Dialium schlechteri (DS), Garcinia livingstonei (GL), and Syzygium cordatum (SC), collected over three consecutive years from seven locations. Antioxidant compounds including total polyphenol content (TPC), total flavonoid content (TFC), and vitamin C

Cellulose derived Diels-Alder covalent adaptable networks: a route towards recyclable thermosets

Plastmaterial utgör idag en fundamental del av vår vardag men användningen av plast är kopplad till två stora problem; den största delen produceras av fossilbaserade resurser och endast en bråkdel av materialen återvinns. Härdplaster är särskilt svåra att återvinna på grund av deras permanenta tvärbindningar vilket är suboptimalt. Ett alternativt tillvägagångssätt för att skapa tvärbundna materialPlastic materials have grown to become essential in our everyday lives but the usage of plastics is connected to two significant issues; the major part is produced from fossil-based resources and only a fraction of the materials is recycled. Thermosets are especially difficult to recycle due to their permanent crosslinks, which is suboptimal. An alternative approach for crosslinking emerging in th

Utformning av integrerade stöd med grova stålrörspålar för järnvägsbroar

Syftet med denna uppsats är att utifrån ett referensobjekt undersöka hur broar med integrerade stöd grundlagda på stålrörspålar kan utformas för att uppfylla högt ställda deformationskrav för höghastighetståg. Användningen av integrerade stöd är stor i bland annat USA och England. De främsta fördelarna med integrerade stöd är att de innebär att broar kan utformas utan lager och fogar. Detta är fö

Linking small-scale topography with microclimate, plant species diversity and intra-specific trait variation in an alpine landscape

Background: Small-scale topographic complexity is a characteristic feature of alpine landscapes, with important effects on alpine plant distribution. Aims: We investigated the links between small-scale topographic complexity and resultant microclimatic heterogeneity, vascular-plant species richness and beta diversity, and realised niche width and trait variation of some target species. Methods: We

Does stronger pollen competition improve offspring fitness when pollen load does not vary?

PREMISE OF THE STUDY: Competition among pollen grains from a single donor is expected to increase the quality of the offspring produced because of the recessive deleterious alleles expressed during pollen-tube growth. However, evidence for such an effect is inconclusive; a large number of studies suffer from confounding variation in pollen competition with variation in pollen load. METHODS: In thi

Feasibility of a Pumped Storage Hydro & Wind-Power Hybrid Setup

Energilösningen för Framtiden: Vattenpumplagring & Vindkraft Genom åren har användningen av fossila bränslen minskat, samtidigt som vi sett en ökning av förnybara energikällor som vindoch solkraft. Sverige står dock inför en utmaning: vindens oförutsägbara natur skapar problem för elnätets stabilitet. Denna rapport utforskar möjligheterna kring el-lagring genom vattenpumplagring kopplat till The introduction of the Renewable Energy Directive 2009, increased the renewable energy sources (RES) in the European Union (EU) and especially Sweden. Given the uncontrollable nature of weather patterns, energy generation is likely to become more volatile, thereby elevating the risk of curtailment and negative energy prices. The electricity demand in Sweden is also poised to rise sharply in the u

Multiple ancestries and shared gene flow among modern livestock guarding dogs

Livestock guarding dogs (LGDs) have been used to protect livestock for millennia. While previous works suggested a single origin of modern LGDs, the degree and source of shared ancestry have not been tested. To address this, we generated genome-wide SNP data from 304 LGDs and combined it with public genomic data from 2,183 modern and 22 ancient dogs. Our findings reveal shared ancestry and extensi

Att spela på elevers drömmar: en musiklärares ensemblepraktik på gymnasieskolans estetiska program

Föreliggande studie intresserar sig för hur en lärare kan tillvarata och skapa utrymme för elevers personliga drömmar, mål och visioner med att studera på det estetiska programmet inom ramen för ensembleundervisningen. Vidare undersöker studien hur en lärare, med utgångspunkt i elevernas drömmar, mål och visioner kan skapa förutsättningar för elever att känna motivation. Den tidigare forskning somThis study is interested in how a teacher can make use of and create space for students’ personal dreams, goals and visions by studying the aesthetic program within ensemble teaching. Furthermore, the study investigates how a teacher, based on the students’ dreams, goals and visions can create an environment where students can feel motivated. Previous research on the subject covers students’ desir

Connectivity and climate influence diversity–stability relationships across spatial scales in European butterfly metacommunities

Aim: Anthropogenic-driven biodiversity loss can impact ecosystem stability. However, most studies have only evaluated the diversity–stability relationship at the local scale and we do not fully understand which factors stabilize animal populations and communities across scales. Here, we investigate the role of species dispersal ability, climate, spatial distance and different facets of biodiversit

Decay of Correlations for the Gauss Map

We study the Gauss map and derive certain statistical properties, specifically upper bounds on the decay of correlations. The method is due to Liverani \cite{Main_Liverani}, which in turn is based on foundational work by Birkhoff \cite{LatticeTheory}. One defines a cone of functions, and then considers the induced Hilbert metric associated to the cone. A strict contraction in this metric gives exp

Poly(arylene alkylene)s with Tetrazole Pendants for Alkaline Ion-Solvating Polymer Electrolyte

Alkaline ion-solvating membranes derived from a tetrazole functionalized poly(arylene alkylene) are prepared, characterized and evaluated as electrode separators in alkaline water electrolysis. The base polymer, poly[[1,1′-biphenyl]-4,4′-diyl(1,1,1-trifluoropropan-2-yl)], is synthesized by superacid catalyzed polyhydroxyalkylation and subsequently functionalized with tetrazole pendants. After equi

Cold War Conduct : Knowledge Transfer, Psychological Defence, and Media Preparedness in Denmark Between Sweden, Norway, and NATO, 1954–1967

Employing the Foucauldian term ‘conduct’, this article explores how social resilience and morale became a target of state intervention in Denmark during the Cold War. ‘Psychological defence’ was a Cold War phenomenon designed to bring an imagined future war into a space of control as well as a tool for the authorities’ exercise of power in case another world war became a reality.

Integrated Assessment of Climate Change and Forest Management Impacts on Carbon Fluxes and Biomass in a Southern Boreal Forest

Boreal forests play a crucial role in global carbon sequestration and storage, yet their vulnerability to climate change remains a significant concern. We present results from simulations with the process-based dynamic global vegetation model LPJ-GUESS of the combined effects of climate change and forest management on the carbon sink capacity of a boreal forest in southern Sweden. We compared two
