Computer vision applications are very useful to study animal movements, but due to their intrinsic complexity they are challenging to design, implement, and use properly. We here describe a calibration procedure for a laboratory stereo vision system for tracking zooplankton in three dimensions (3D). We demonstrate the crucial importance of using a correct calibration for proper interpretation of a
Aims Vegetation stimulates, in general, soil mineral weathering. It has been hypothesized that plant-associated microorganisms, especially ectomycorrhizal fungi play a major role in this process. We studied apatite dissolution in a vegetation gradient in southern Norway to test the role of ectomycorrhizal vegetation on mineral weathering. Methods A natural occurring lead contamination, probably pr
Syftet med studien var att kvalitativt undersöka kvinnliga fotbollsspelares upplevelse av att nå elitnivå. Semistrukturerade intervjuer användes och totalt intervjuades tre deltagare. Intervjuerna analyserades med IPA (Interpretative Phenomenological Analysis) som metodologisk ansats. Totalt kunde fem teman urskiljas som centrala i upplevelsen av elitnivå: tankar och känslor kopplade till övergångThe purpose of this study was to qualitatively explore the experience of reaching the elite level for women in football. Semi-structured interviews were conducted with three participants. The interviews were analysed using Interpretative Phenomenological Analysis (IPA). In total, five themes emerged: thoughts and feelings associated with reaching the elite level, social support, gender identity, m
This thesis explores the reception system for unaccompanied refugee minors (URMs) in Sweden, with a focus on preventive and responsive measures to sexual violence. The aim is to understand the professional challenges of actively working against sexual vulnerability and violence. Furthermore, it explores the interrelation between changes in laws and legislation and shifts in the public discourse, w
Effective human input devices for computer control are very important to quadriplegics and others with severe disabilities. This paper describes a framework for computer control without need for special PC software or drivers. The framework is based on a tongue control system recently developed at Center for Sensory-Motor Interaction (SMI), Aalborg University. The framework provides emulation of a
Contributing to the design update phase of the European Spallation Source ESS-scheduled to start operation in 2019-a test beamline is under construction at the BER II research reactor at Helmholtz Zentrum Berlin (HZB). This beamline offers experimental test capabilities of instrument concepts viable for the ESS. The experiments envisaged at this dedicated beamline comprise testing of components as
We tested the habitat filtering hypothesis by measuring the phylogenetic structure in marine bacterial communities before and after experimentally induced stress. The habitat filtering hypothesis predicts that phylogenetic clustering (mean relatedness) should increase as the environment becomes suitable for only a subset of the original community. We show that community composition and phylogeneti
Studiens syfte var att nå en fördjupad förståelse av timeouter i handboll, hur de används och vad som kommuniceras. En fallstudie genomfördes med ett herrhandbollslag i den högsta divisionen i svensk handboll. En kombinerad kvantitativ och kvalitativ metod användes där tränarens kommunikation kategoriserades med hjälp av Hasties (1999) instrument för skattning av tränarkommunikation under timeout.The purpose of this study was to gain a deeper understanding of timeouts in handball, how they are used and what is communicated. A case study was performed with a men’s handball team in the top division in Swedish handball. A combined quantitative and qualitative method was used where the coach’s communication was categorized using Hastie’s (1999) instrument for assessment of coach communication
Popular Abstract in Swedish Syfte Syftet med denna avhandling var att undersöka om barn födda i Sverige till invandrare (icke-Svenskar) hade en ökad risk för typ 1 diabetes (T1D) och om immunogenetiska markörer för T1D (HLA och icke-HLA genetiska faktorer samt ö-cellsantikroppar) skiljde sig från svenska T1D barn (Svenskar). Målsättningen var också att analysera ärftliga förutsättningar (T1D och TThis thesis examined whether the offspring of immigrants (non-Swedes) to Sweden are at increased risk of Type 1 Diabetes (T1D) when they are born or live in Sweden. It also evaluated if their T1D and T2D-related genes differed from Swedish patients and whether this genetic heritage determined the types and existence of islet autoantibodies at time of diagnosis and affected the classification of di
Calcicole plant species are vulnerable to acidification and fertilization, caused by deposition and changes in land use, since they are adapted to nutrient-poor calcareous conditions. In this study we used vegetation data (vascular plants, bryophytes and lichens) from 1964 and 1985 and stored soil samples from 1966 to investigate long-term soil chemistry and vegetation changes in a semi-natural, s
Biochar application to soils has potential to simultaneously improve soil fertility and store carbon to aid climate change mitigation. While many studies have shown positive effects on plant yields, much less is known about the synergies between biochar and plant growth promoting microbes, such as mycorrhizal fungi. We present the first evidence that arbuscular mycorrhizal (AM) fungi can use bioch
The activity of saprotrophic fungi and bacteria, and the balance between them, can affect decomposition. Arbuscular mycorrhizal (AM) fungi are also important for the nutrient and energy transfer in soil. Microbial community composition and activity are believed to have seasonal patterns, and are known to be highly influenced by environmental factors such as pH and nutrient conditions. To evaluate
The two-body photodisintegration of He-3 has been investigated using tagged photons with energies from 14-31 MeV at MAX-lab in Lund, Sweden. The two-body breakup channel was unambiguously identified by the (nonsimultaneous) detection of both protons and deuterons. This approach was made feasible by the overdetermined kinematic situation afforded by the tagged-photon technique. Proton-and deuteron-
Carry-over effects take place when events occurring in one season influence individual performance in a subsequent season. Blood parasites (e.g. Plasmodium and Haemoproteus) have strong negative effects on the body condition of their hosts and could slow the rate of feather growth on the wintering grounds. In turn, these winter moult costs could reduce reproductive success in the following breedin
In the present study, we aim at relating Forbes' remarkable paper on "The lake as a microcosm", published 125 years ago, to the present status of knowledge in our own research group. Hence, we relate the observations Forbes made to our own microcosm, Lake Krankesjon in southern Sweden, that has been intensively studied by several research groups for more than three decades. Specifically, we focus
Popular Abstract in Swedish Membranproteiner är tämligen svåra att digerera med enzym som trypsin. Mindre specifika enzym såsom elastase och pepsin har dock visat sig mer effektiva. Databassökningar med dessa icke-tryptiska peptider är mindre verkningsfulla pga avsaknaden av laddning vid peptidens N-terminal och C-terminal samt brist på sekvensspecificitet. Vi beskriver en metod med specifik N-teMembrane proteins are fairly refractory to digestion especially by trypsin. Less specific proteases like elastase and pepsin are much more effective. However database searching using non-tryptic peptides is much less effective due to the lack of charge localisation at the N- and C-termini and the absence of sequence specificity. We describe a method for N-terminal specific labelling of peptides fr
Artiklarna i denna antologi belyser hur nutida forskningsrön och vetenskaplig diskussion om frågor som kaos och komplexitet, förutsägbarhet och kausalitet, emergens och ordning påverkar traditionella religiösa och vetenskapliga tankar om oförutsägbarhet, slump, ändamål och skapelse. Teologer och naturvetare från sekulär, protestantisk, katolsk och ortodox tradition visar hur ordning och oordning h
