We derive stellar ages, from evolutionary tracks, and metallicities,from Strömgren photometry, for a sample of 5828 dwarf and sub-dwarfstars from the Hipparcos Catalogue. This stellar disk sample is used toinvestigate the age-metallicity diagram in the solar neighbourhood. Suchdiagrams are often used to derive a so called age-metallicity relation.Because of the size of our sample, we are able to q
In the present experiment we examined reality monitoring for socially sensitive and non-sensitive information relating to prejudice (negative and positive beliefs about an ethnic minority). At study, participants either imagined or perceived negative or positive attributes in connection with photographs of target individuals that clearly varied in ethnicity (non-western or western). At test, the t
The aim of this study is to examine the rewriting of the memoirs of the former pirate Alexander Olivier Exquemelin, Los Piratas de América, originally published in Amsterdam in 1678, which the Mexican writer Carmen Boullosa carries out in two recent novels: Son vacas, somos puercos and El médico de los piratas. In the light of Gérard Genette’s theory of hypertextuality this study deals with the fo
Objective: Individual-based studies on restricted geographical settings have suggested that nonsteroidal anti-inflammatory drugs (NSAIDs) may precipitate congestive heart failure. As NSAID use is very extensive, it might increase the occurrence of symptomatic heart failure in the general population. Therefore, in order to study the impact of NSAID utilisation (prescribed and over the counter) on h
Previously it demonstrated that in the absence of Ca2+ entry, evoked secretion occurs neither by membrane depolarization, induction of [Ca2+]i rise, nor by both combined (Ashery, U., Weiss, C., Sela, D., Spira, M. E., and Atlas, D. (1993). Receptors Channels 1:217-220.). These studies designate Ca2+ entry as opposed to [Ca2+]i rise, essential for exocytosis. It led us to propose that the channel a

Traditional 14C urea breath tests are normally not used for younger children because the radiation exposure is unknown. High sensitivity accelerator mass spectrometry and an ultra-low amount (440 Bq) of 14C urea were therefore used both to diagnose Helicobacter pylori (HP) infection in seven children, aged 3–6 years, and to make radiation dose estimates. The activity used was 125 times lower than
The long-term shoreline evolution at Hai Hau Beach in the Red River Delta, Vietnam was simulated using the one-line model GENESIS (Hanson, 1989). Dikes were modelled as seawalls and the sediment continuity equation in GENESIS was modified to take into account the offshore transport of fine-grained sediment. The model performed well, reproducing the magnitude and trend of the long-term shoreline ch
Popular AbstractJag är konstnär! beskriver konstnärskapet i en mindre konstvärld ur ett sociologiskt perspektiv. Den lilla konstvärlden är specifik. Den utmärks av en hög grad av överblickbarhet, igenkännande och osäkerhet. Igenkännandet kan till en del minska den osäkerhet man känner inför vad som är konst och vad som inte är det, och vem som bör tillskrivas en konstnärsroll och vem som bör utdefI am an artist! describes the process of recognition that surrounds being an artist in a local art world; how boundaries are drawn up not only by the artists themselves, but also others in the art world. It also describes the advantages and restrictions of a local art world as far as the artist´s possibilities to be seen, mentioned, judged and distributed, and also the specific general view which
Different aspects of hybrid control systems are treated: analysis, simulation, design and implementation. A systematic methodology using extended Lyapunov theory for design of hybrid systems is developed. The methodology is based on conventional control designs in separate regions together with a switching strategy. Dynamics are not well defined if the control design methods lead to fast mode sw
We present angle- and polarization-dependent photoelectron spectra of solid C-60 recorded over a large range of emission angles. The bands derived from the three highest molecular orbitals are very similar in their angular distribution and show a strong dependence on both light polarization direction and sample orientation. We show that a molecular emission pattern modified by solid-state effects
Weekly resource use data for local wound treatment was collected from a clinical survey (138 patients). Annual costs were calculated from the weekly resource usage multiplied by unit costs and published epidemiological prevalence data for Sweden. The average weekly cost was 101 euro, though it differed depending by ulcer size. The total direct annual cost of venous leg ulcers in Sweden could be es
Objectives: At the request of the European Commission and in the framework of the European Machinery Directive, research was performed in five different laboratories to develop specifications for surface temperature limit values for the short-term accidental touching of the fingertip with cold surfaces. Methods: Data were collected in four laboratories with a total of 20 males and 20 females perfo
