Many animals use visual signals to navigate through their environment, and among the top navigators in the animal world we find insects. Even though their brains are incredibly small, insects are able to find their way using, for example, a strategy known as path integration. By updating the distance and direction travelled the insect is able to find the way back to its point of origin along a str

Arctic environments are subject to high seasonal variability. For the species inhabiting these latitudes, adaptation to both harsh winters and milder summers is necessary. Among the few mammals capable of sustaining such variable circannual conditions, the arctic fox (Vulpes lagopus) shows remarkable morphological and physiological traits that enable individuals to remain in the Fennoscandian tund

At the forefront of the fourth industrial revolution, technologies such as digital twin seek to shift the way industrial companies operate. A digital twin is a virtual replica of a product, system or process. Historically, the focus has been on representing single objects but it is now shifting to interconnected processes, such as supply chains. Advanced versions of a supply chain digital twin can

Yttemperatur och interspecifika interaktioner påverkar sympatriska arters närvaro runt en hajdykningsbåt i Gansbaai, Sydafrika Rock- och hajpopulationer (Elasmobranchii) minskar drastiskt i de flesta hav på planeten och arter riskerar utdöende på grund av kommersiellt fiske och bifångst som dödar 100 miljoner hajar årligen. Ekoturism såsom hajdykning i bur förlitar sig på hållbara och hälsosamma Elasmobranch populations are decreasing rapidly worldwide due to anthropogenic exploitation such as commercial fishing, where targeted shark fisheries and accidental bycatches harvest more than 100 million sharks yearly. Ecotourism operations such as shark-cage diving operators strongly rely on sustainable and functioning ecosystems and wildlife in order to utilize these for tourism and educationa

The purpose of this BA thesis is to investigate the attitude young speakers of Swedish between the ages nineteen and twenty-eight have to English swearwords in Swedish, compared to Swedish swearwords in Swedish. Seven swearwords were included for each language, resulting in fourteen swearwords in total. The study is divided into i) a quantitative study and ii) a qualitative study, both using a que

Trees in the boreal region provide enormous amounts of carbon storage in their above ground biomass as woody trunks, as well as below ground in their root systems. Mycorrhizal fungi also act as a carbon store in boreal forests and receive carbon from the host tree in the form of photosynthates. Partitioning of a tree's carbon above or below ground is highly dependent on other nutrient cycles s

Kan mindfullness hjälpa unga som mår psykiskt dåligt? Det är allt fler i samhället som mår psykiskt dåligt och antalet unga med psykisk ohälsa ökar. Psykisk ohälsa handlar om hur vi mår och trivs med livet samt hur vi hanterar livets upp- och nedgångar. För många som mår psykiskt dåligt tar det emot att söka professionell hjälp då det finns en skam för att inte kunna hantera sin egen livssituatio

Vad har immunsystemet med neuroblastom att göra? Jo, många olika slags immunceller har visat sig infiltrera vävnaden i neuroblastom-tumörer. Därför undrar man nu hur dessa immunceller påverkar tumörerna, hur de hamnar där och om det finns någon koppling mellan infiltration av olika immunceller och överlevnad hos patienter med neuroblastom. Neuroblastom är en typ av barncancer som drabbar ca. 1

"Bland mästare och mentorer" är ett examensarbete som syftar till att undersöka hur fyra kompositionslärare på högskoleförberedande musikutbildningar beskriver sin undervisning i relation till sitt hantverk som tonsättare/kompositörer. Studien har ett särskilt fokus på det självständiga övandet i komposition och undersöker hur lärare själva gör och vad av detta som de vill omsätta till u"Among Masters and Mentors" is a thesis which aims to investigate how four composition teachers in college preparatory music education programs view their teaching compared to their craftmanship as composers. The study has a special focus on the independent practice of composition and examines how the teachers themselves practice and which aspects of this they wish to transfer into their

Evolution av skadeinsekter och deras naturliga fiender Dagens jordbruk kan använda sig av biologisk kontroll som ett alternativ till kemiska bekämpningsmedel. Naturliga fiender till skadeinsekter introduceras då i jordbrukslandskapet för att begränsa skadeinsekterna. Kunskap om hur skadeinsekter anpassar sig över tid kan vara avgörande för hur effektiv biologisk kontroll är. En generell teoretiskBiological control is a form of agricultural practice, where a pest’s natural predators are introduced or favored in the agricultural landscape to increase predation on the pests. This increase in predation is beneficial for production but can also drive co-evolutionary adaptation and even diversification within the pest communities which, in turn, may lead to predator responses and diversificatio

Wood decay fungi are often classified as either brown rot or white rot, depending on their mechanism of accessing nutrients in wood. This dichotomy assumes that white rot fungi break down lignin with various enzymes, while brown rot fungi leave it mostly unmodified and instead bypass it with diffusion of small molecules to reach the desired hemicellulose and cellulose. The effect of different sour

Finns alltjämt spår av BT Kemi i åvatten och sanerare? En av Sveriges största miljöskandaler håller på att klaras upp med en slutlig sanering. I 50 år har föroreningarna legat i marken och inte brutits ned. Sedan 1970-talet har kemikalier spridit sig till naturen och påverkat ekosystem och människor. I världen är bekämpningsmedel ett stort problem ur miljö-och hälsosynpunkt och kan skada männiPesticides are considered to protect crops from damage from example weeds, insects and molds but they are a global problem from environmental and health point of view. A pesticide producing factory in Sweden, known as BT Kemi, mainly produced phenoxyacetic acids, chlorophenols and chlorocresols between 1965 and 1977. Pollutants have been spread into the environment when the factory was active. The

Although primarily targeting the respiratory system, coronavirus disease 2019 (COVID-19) also manifests with central nervous system (CNS)-related symptoms in up to 80% of the patients. Little is known not only about SARS-CoV-2 neuropathology, but also about the clinical course of pre-existing CNS autoimmune disease and concurrent SARS-CoV-2-infection. Multiple sclerosis (MS) is the most frequent

Clinical models are increasingly employed in medical science as either diagnostic or prognostic aids. Machine-learning methods are able to draw links in large data that can be used to predict patient risk and allow more informed decisions regarding treatment and medication intervention. An advanced clinical predictor, HRDetect, can determine loss of homologous recombination-based repair pathways i

"You are part of something bigger... You work with life.": A study about social horticultural projects- gains, obstacles and possibilities. The public interest in gardening and horticulture is growing, in Sweden and internationally. Despite this, social horticultural projects still earned little attention in Swedish research. This paper aimed to examine social projects that use horticul

The purpose of this study was to explore the situation of disabled children and their access to education in a village in northern Bali, Indonesia. The method used was ethnographic with participant observations, and the empirical material was collected during six weeks with ten families in their homes and at the facility of an NGO. Eight volunteers at the NGO were also informants. The questions th

The identification of the characteristics of drought are of great importance in water resources planning and management. This study explored the characteristics of drought at Limpopo River Basin (LRB) from 1918 to 2018. Two time scales were used; they were the 3-month and 12-month time scales using the Standardized Precipitation Evaporation Index (SPEI), with the aim of studying the characteristic
