Using high-resolution spectra of nearby F and G dwarf stars, we have investigated the detailed abundance and age structure of the Hercules stream. We find that the stars in the stream have a wide range of stellar ages, metallicities, and element abundances. By comparing to existing samples of stars in the solar neighborhood with kinematics typical of the Galactic thin and thick disks, we find that
A numerical study was carried out to examine the development of duct flows being affected by combined buoyancy force-driven secondary flow and mass transfer. The developing flow and heat transfer have been simulated numerically for a horizontal fuel cell duct with rectangular and trapezoidal cross section. Constant heat flux and mass transfer rate are prescribed on the bottom wall, while thermal i
The 65-kDa glutamic acid decarboxylase (GAD65) autoantibodies (GAD65Abs), commonly found in type 1 diabetes mellitus (T1DM) patients, are also found at lower frequencies in type 2 diabetes mellitus (T2DM) patients. GAD65Abs in T1DM patients are epitope specific, in contrast to those found in other GAD65Ab-positive individuals, including T2DM patients. Our aim was to assess whether epitope-specific
Rodent models have been developed to study the pathogenesis of diseases caused by Helicobacter pylori, as well as by other gastric and intestinal Helicobacter spp., but some murine enteric Helicobacter spp. cause hepatobiliary and intestinal tract diseases in specific inbred strains of laboratory mice. To identify these murine Helicobacter spp., we developed an assay based on PCR-denaturing gradie
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
Rapporten behandlar frostsprängning, saltangrepp, vidhäftning, rörelser - sprickbildning samt åldring - och nedbrytning. Mekanismer, materialegenskaper och provningsmetoder redovisas och kommenteras. Kortfattade resonemang kring områdena vattenavvisande ytbehandling, nedbrytning p g a luftföroreningar samt redovisning av materialegenskaper.
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
