The polymerizable N,N-dimethylacrylamide (DMAA) is added to the lamellar liquid crystalline system formed by the anionic surfactant Aerosol OT and water. Small angle X-ray scattering, gives the same bilayer thickness and hydrophilic group cross-sectional area as without DMAA, and an environment sensitive fluorescent probe indicates that DMAA is likely to be in the water layers between the AOT bila

Popular Abstract in Swedish Avhandlingen handlar om naturföreställningar i resereklam och bland re-senärer. Syftet var att analysera hur natur framställs i reklambilder för resor, vad reklamens framställning av natur har för betydelse för vad resenärer vill uppleva och upplever i samband med sin resa samt med vilka argument och bilder resenären själv väljer att återskapa upplevelserna av sin resa It is commonly believed that we live in a culture that is increasingly permeated by visual images. One category of images that we encounter everyday in different media, and that constitutes a large and growing part of media content, is advertisements. Advertisements also have a specific purpose and the images represent, make meaning of, and convey sentiments about phenomena. In this dissertation,

Popular Abstract in Swedish Interaktionen mellan syn- och balanssinne för orienterings- och balansförmåga studerades hos friska försökspersoner, alkoholpåverkade friska försökspersoner och personer med en väldefinierad, ensidig vestibulär skada: translabyrintär vestibulär nervavskärning pga vestibularisschwannom. Balansförmåga i stående studerades med posturografi. Visuo-vestibulär orienteringsförThis thesis aimed to investigate visual-vestibular interactions in healthy subjects and in patients with a well defined unilateral vestibular lesion (vestibular schwannoma before and six months after translabyrinthine surgery). Visual information is particularly important for balance control during perturbed stance. The physical act of having the eyes open or closed affects motion strategy in pos

Today, embedded systems often consist of many different processing, communication, and memory units. This makes an embedded system a multiprocessor system. There are usually many possible multiprocessor architectures and therefore we need tool support for fast evaluation of numerous design alternatives. However, there is a lack of this type of tools which is partially caused by the inherent comple

Sixty-two animal enterococci were examined for their binding of bovine fibrinogen, porcine fibronectin, bovine lactoferrin, bovine apotransferrin and human holotransferrin in the particle agglutination assay (PAA). Individual strains expressed binding of selected glycoproteins to various degrees (0, 1, 2, 3), whereas bovine fibrinogen binding of enterococci from goats, rabbits and rodents was the

The relationship between urinary levels of cotinine (U-cotinine) and arsenic (U-As), blood levels of cadmium (B-Cd), blood levels of lead (B-Pb), lung function, and questionnaire data on smoking habits were studied in 107 parents and their 46 children (7-10 y of age). There was a statistically significant relationship between the reported amount of tobacco smoked and U-cotinine levels. Nonsmokers

Few attempts to control forest insects by means of pheromone mating disruption have been reported. The first such experiments with the European pine sawfly, Neodiprion sertifer (Hymenoptera: Diprionidae), resulted in nearly complete trap catch reduction, but no effects on population density or sex ratio were noted. Unmated females lay eggs, which develop into males only. Therefore, if mating disru

We present a theoretical analysis of the interfacial tensions of microemulsions in ternary systems water-oil-nonionic surfactant. For surfactants based on oligo-ethylene oxide head-groups the temperature can be used to tune the properties of the microemulsions. Explicit expressions are derived for the interfacial tension of both droplet and bicontinuous microemulsions. We also discuss the effect o

Basal kroppskännedom är en metod som används allt flitigare i nordisk sjukgymnastik. Basal kroppskännedom handlar om grundläggande rörelseförmåga, rörelsebeteende och kroppsmedvetande. Det handlar om hållning, balans och koordination, och om muskulära spänningar i kroppen.
