A data set of adaptive optics images has been analyzed in order to study the effects of angular anisoplanatism and to characterize Mauna Kea nighttime turbulence. The data set consists of a selection of Galactic center images obtained with the adaptive optics instrument Hokupa'a and the near-infrared camera QUIRC on the Gemini-North 8 m telescope. Using the Strehl ratio and the FWHM as tracers for

Despite the fact that the origin of human immunodeficiency virus (HIV) being a contamination and a mutation originating from primates is well-documented alternative narratives are often being heard ofespecially in sub-Saharan Africa. One such narrative is about HIV being man-made in a military laboratory in the United States. In this article, it is shown how this narrative was fabricated by the in

Populärvetenskaplig sammanfattning: Klimatväxlingarna under sista istiden har alltid varit en debattfråga. Denna istids kallaste period inträffade för cirka 20.000 år sedan och benämns "istidsmaximum". Då var havsytan hundratjugo meter lägre än idag och det mesta vattnet var bundet i inlandsisarna. Klimatväxlingar försöker dagens kvartärgeologer att fastställa med en så bra tidsutlösningHigh-resolution analyses of sediments from two sites in Blekinge, south-eastern Sweden (the former Lake Togölen and Lake Bredsjön), were evaluated in order to establish the pollenstratigraphical position of the second and final drainage of the Baltic Ice Lake in relation to the Younger Dryas-Preboreal pollen zone transition. Remanent magnetisation and magnetic susceptibility were used to correlate

The RESET test for functional misspecification is generalised to cover systems of equations, and the properties of 7 versions are studied using Monte Carlo methods. The Rao F -test clearly exhibits the best performance as regards correct size, whilst the commonly used LRT (uncorrected for degrees-of-freedom), and LM and Wald tests (both corrected and uncorrected) behave badly even in single equati

Popular Abstract in Swedish Som ett skepp uti vilda havet, den kristna församlingen i ärkebiskop Laurentius Petris verk I 1593 års Uppsala mötes "förening om läran, ceremonier och kyrkotukt" finns följande avsnitt : Thernäst bejake och vederkännes vi oss alldeles vele holle vidh the Apostoliske, Niceniske och Athanasii symbola, såsom och vidh then äldste, rätte och oförrandrede Ausburgiske confeThe aim of this thesis is to present the ecclesiology of Laurentius Petri, a former student at Wittenberg who was archbishop of Uppsala from 1531 to his death 1573. He had a decisive role in the founding of the Church of Sweden, especially through his Swedish Church Ordinance(1571). Nevertheless most of his seventy-three writings are little known and have been rarely studied. Chapter one st

Popular Abstract in Swedish Kroniskt obstruktiv lungsjukdom (KOL) är en allvarlig folksjukdom vars huvudsakliga orsak är tobaksrökning. Det är den enda av de viktigaste dödsorsakerna som ökar och år 2020 beräknas KOL utgöra den 4:e vanligaste dödsorsaken i världen. Flera studier har försökt att bestämma förekomsten (prevalensen) av KOL i befolkningen men tyvärr har de oftast använt olika metoder oBackground – Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality worldwide. However, there is little information on the prevalence and particularly on the incidence of COPD. Also, apart from the importance of tobacco smoking and a1-antitrypsin deficiency, information on contributing risk factors for the development of COPD is limited. Hypotheses – 1. Spi

In this text learning is regarded as something done via communicative acts. Meaning is constructed and maintained in a communicative process where responses are exchanged between individuals. Some individuals do this often and intensively and by doing this, in co-operation with others, develop with them unique and shared perspectives, and through these perspectives they view the world and construc

This paper reports on a one-to-one aspect of the articulatory-acoustic relationship, explaining how acoustic segment boundaries are a result of the rapid movements of the active articulators. In the acceleration profile, these are identified as acceleration peaks, which can be measured. To test the relationship, consonant and vowel segment durations are compared to articulatory posture intervals b
