Background Several models for prediction of acute coronary syndrome (ACS) among chest pain patients in the emergency department (ED) have been presented, but many models predict only the likelihood of acute myocardial infarction, or include a large number of variables, which make them less than optimal for implementation at a busy ED. We report here a simple statistical model for ACS prediction th
Ozone dry deposition measurements were carried out during approximately one year over a flat grass field in Portugal. The results show prominent diurnal and seasonal patterns in deposition flux, dry deposition velocity and surface resistance, especially for the daytime period. Dry deposition velocities vary diurnally from a minimum of 0.1 cm s(-1) during the night to a maximum of 0.7-0.5 cm s(-1)
This study evaluates the effect on the skeleton of physical activity from age 9 to 16. In 42 girls and 44 boys, bone mass and bone size were evaluated longitudinally by dual-energy X-ray absorptiometry (DXA) from ages 13 to 16. Physical activity from ages 9 to 13 was cross-sectionally evaluated at baseline (age 13). Girls with high physical activity from ages 9 to 13 at baseline had higher femoral
BACKGROUND--Continuous epithelial shedding and restitution processes may characterise the airways in diseases such as asthma. Epithelial restitution involves several humoral and cellular mechanisms that may potentially be affected by inhaled anti-asthma drugs. The present study examines the effect of a topical steroid on epithelial restitution in vivo in the guinea pig. METHODS--The airway epithel
Popular Abstract in Swedish Hawaiianernas liv och historia har dokumenterats allt sedan första kontakten med västerländska äventyrsresanden i slutet av 1700-talet. I samband med amerikanska missionärers ankomst år 1820 introducerade och etablerade dessa missionärer en puritansk lära och kunskapsförmedling via det skrivna ordet. Mötena mellan de olika kulturerna har beskrivits som fredliga. Dock haThe life and history of the Hawaiians has been documented ever since the contact with Western adventurers at the end of the 18th century. In connection with the arrival of American missionaries in 1820, these missionaries introduced and established a puritanical doctrine and method of communicating knowledge by way of the written word. The encounters between the different cultures have been descri
Popular Abstract in Swedish Mixotrofa växtplankton i sjöar Vad är växtplankton? I hav och sjöar finns det mängder av mikroskopiska fritt svävande alger – växtplankton. Liksom gröna växter på land använder växtplankton solljuset för att producera energi och syre genom fotosyntes. För att algerna ska kunna växa behöver de förutom ljus ett flertal näringsämnen varav de viktigaste är kväve (N) och fSome phytoplankton have the ability to combine phototrophy and heterotrophy within the same individual, which is called mixotrophy. In this thesis, I adress mixotrophy and competitive interactions of mixotrophs and obligate auto- or heterotrophs in relation to the availability of nutrients, light and prey. In addition, I examine the biomass of mixotrophic phytoplankton and their grazing impact on
Samples from several WWTPs in Sweden, operating either with chemical precipitation of phosphorus, biological phosphorus removal or combination of the two, were analysed for separation and dewatering properties. The main parameters of interest were capillary suction time (CST), extracellular polymeric substances (EPS), metal ions concentration, filterability and compressibility of the sludge. Enhan

In this study the author seeks to develop Historical Realism as a new approach to International Relations. Drawing on recent theoretical developments in International Relations and Historical Sociology it is argued, first, that a distinction between constitutive and causal theory is necessary and, second, that this distinction makes comparisons at a high level of abstraction across time and space
Popular Abstract in Swedish Himmelsfärdsskildringar återfinns i en rad religiösa texter från vår tideräknings början. Dessa berättelser har kommit att utgöra ett återkommande tema i religionshistorisk forskning om antikens religioner. Den här boken handlar om några tidiga judiska och kristna himmelfärdstexter. De flesta av dem utgör en del av den apokalyptiska litteraturen. Himmelfärdsmotivet harIn the beginning of the Common Era, a number of religious texts were written recounting heavenly journey adventures. These narratives have come to constitute a recurring theme in research regarding ancient religions. Round Trips to Heaven features several early Jewish and Christian heavenly journey texts. Most of them are included in the apocalyptic literature. During the earlier research, the he
Let c(x) = inf {t > 0: Q(t) greater than or equal to x} be the time of first overflow of a queueing process 1001 over level x (the buffer size) and Z = P(T(X) less than or equal to T). Assuming that {Q(t)) is the reflected version of a Levy process {X(t)} or a Markov additive process, we study a variety of algorithms for estimating z by simulation when the event {tau(X) less than or equal to T} is
In an investigation by the Swedish Cancer Society, an expert group described the present status, critical issues and future aspects and potentials for each of nine major areas of radiation therapy research. The present report deals with therapy with radiopharmaceuticals.
Based on a retrospective study of 19 neuropathologically verified cases with frontotemporal dementia (FTD), neuropsychiatric symptoms related to behavioral disturbances and their psychosocial consequences were studied. The results indicate that frontotemporal dementia is often misdiagnosed early in the clinical course. Behavioural features with impaired social interactions, impaired personal regul
