The behavior of animals is commonly studied in medicine and biology. There is a large variation in what animals are studied, in experimental paradigms and purpose.However, many studies on animal behavior have at least one thing in common - it typically involves measuring or studying the kinematics of the animal. To allow for verifiable and quantitative behavioral analysis, the experiments are recoThe behavior of animals is commonly studied in medicine and biology.

In radiological diagnostics and therapy, it is important that practitioners, referrers, (i.e. radiologists, radiation oncologists and others in healthcare) are aware of how much radiation a patient may receive from the various procedures used and associated health risk. The profession has a duty to inform patients or their representatives of the advantages and disadvantages of specific investigati

Aims The Trump movement displays several key features of a populist movement with a strong leader and a broad unorganized base of followers opposed to a per-ceived liberal elite establishment. In 2024, Trump gained strong support from strata with low income, low education and Hispanic men, previously not strong support-ers of Republicans. This study investigates the preconditions for a populist moAims The Trump movement displays several key features of a populist movement with a strong leader and a broad unorganized base of followers opposed to a per-ceived liberal elite establishment.

Ornamental horticultural plants in domestic gardens can constitute a substantial dispersal pool of potentially invasive species. Understanding garden owners' preferences when selecting plants, their awareness of dispersal pathways and how they manage their gardens is critical for effective invasive species control.

Questions about the existence and temporality of intention in jazz improvisation are investigated based on phenomenological interviews with 48 expert jazz improvisers: Do improvisers intend that which they will play, and, if so, are their conception and execution of a musical idea coincident, or are they separated in time? The findings on improvisatory cognition are summarized and discussed by mea

Popular Abstract in Swedish Inom många områden, exempelvis inom sjukvården, blir det allt vanligare med situationer där stora mängder av bilder behöver analyseras. Ofta kan dessa bildmängder vara så stora att det tar för lång tid för en människa att gå igenom dem. Till exempel kan man med hjälp av datortomografi ta tredimensionella röntgenbilder av människor, något som görs på sjukhus idag. Att gåAt the core of many computer vision models lies the minimization of an objective function consisting of a sum of functions with few arguments. The order of the objective function is defined as the highest number of arguments of any summand. To reduce ambiguity and noise in the solution, regularization terms are included into the objective function, enforcing different properties of the solution. T

Popular Abstract in Swedish Vår hud och våra slemhinnor är ständigt koloniserade med bakterier som lever i fredligt samspel med vår organism. Dessa bakterier tillhör vår normalflora och kan indelas i kommensaler respektive opportunistiska bakterier. Kommensalerna gagnar värden på olika sätt och orsakar inte sjukdom, till skillnad från opportunisterna som under vissa betingelser kan orsaka infektioAbstractBacteria in most environments encase themselves in a hydrated matrix of polysaccharide and protein, forming organized communities called biofilms. In the biofilm bacteria are protected against hostile environments. Biofilms are important clinically because of their persistence despite host defence and their recalcitrance to antimicrobials. This thesis presents three main findings: (i) biof

Popular Abstract in German Spannungsgesteuerte Kalziumkanäle haben eine große Bedeutung in vielen elektrisch erregbaren Zellen, wie z.B. in Nervenzellen und pankreatischen beta-Zellen. Hier werden sie folgendermaßen aktiviert: In der Nahrung enthaltener Traubenzucker (Glukose) wird nach einer Mahlzeit über den Blutstrom im Körper verteilt und in die beta-Zellen über Glukosetransporter aufgenommen.Voltage-gated Ca2+ channels are essential transducers of cellular signals in many electrically excitable cells. In the pancreatic beta-cell they mediate controlled Ca2+ influx, which is the final trigger for Ca2+ dependent release (exocytosis) of the blood glucose lowering hormone insulin. Several subtypes of voltage-gated Ca2+ channels are known and the L-type has been found to be the main contri

Popular Abstract in Swedish Lipasadsorption till fasta ytor studerades med hjälp av in situ ellipsometri. Samtidigt mättes aktiviteten av det adsorberade lipaset in situ genom hydrolys av p-nitrofenylacetat. Adsorption mättes till metylerade kiseloxidytor med varierande grad av metylering samt till rent kiseloxid. Olika lipaser studerades; lipas från Humicola lanuginosa (HLL)­vildtypen (WT) och enThe adsorption of lipases to solid surfaces was studied by means of in situ ellipsometry. In addition, the activities of the adsorbed lipases were measured in situ, by the hydrolysis of p-nitro phenyl acetate. Adsorption was made to methylated silica surfaces with varying degree of wettability as well as to clean silica surfaces. Lipases from Humicola lanuginosa (HLL) ­ the wild-type (WT) and a m

Popular Abstract in Swedish Denna avhandling är inriktad på metoder för att förbättra och utvärdera infrastrukturer för geografiska data (eng. Spatial Data Infrastructure). Syftet har varit trefaldigt: att utveckla ett ramverk för hantering och utvärdering av en infrastruktur, att förbättra tillgängligheten av geografiska data i en infrastruktur, och för att förbättra kartografi i visningstjänsterThis thesis mainly focuses on methods for improving and evaluating Spatial Data Infrastructures (SDIs). The aim has been threefold: to develop a framework for the management and evaluation of an SDI, to improve the accessibility of spatial data in an SDI, and to improve the cartography in view services in an SDI. Spatial Data Infrastructure has been identified as an umbrella covering spatial data

This study investigated how individuals combine information learned across temporally separate events in order to make novel inferences through memory integration, utilising EEG to provide a novel investigation with high temporal resolution. Participants completed an associative inference task (Zeithamova & Preston, 2010) modified for EEG across three experiments, during which they learned st

Purposes: The Body Awareness Questionnaire (BAQ) has been considered the best available measure of body awareness, but it is not currently available in Spanish. Methods: To address this shortcoming, a sample of 281 Spanish participants completed a survey with a Spanish version of the BAQ, as well as the Body Appreciation Scale (BAS-2), the Self-Compassion Scale-Short (SCS-S) and the New Sexual Sat

The legal position regarding the implementation of the IPRED directive has been uncertain and controversial. The relationship between copyright and privacy is complex and protection of the economic rights has been in need of improvement, while the same thing can be argue for safeguarding of the security of personal information in the growing information society. The ruling in the Ephone case has
