Population stratification occurs in case-control association studies when allele frequencies differ between cases and controls because of ancestry. Stratification may lead to false positive associations, although this issue remains controversial(1-4). Empirical studies have found little evidence of stratification in European-derived populations, but potentially significant levels of stratification
Karyotype structures of Scenedesmus acuminatus (Lagerch.) Chod. and Scenedesmus pectinatus Meyen are compared. The karyotype of S. acuminatus (n = 5) is described for the first time. It reveals four large metacentric and one large submeta centric chromosomes (4M + 1SM). The established karyotype differences have been helpful in clarifying the taxonomic position of these two species. The cytologica
AIM: This study intended to illuminate nursing management in a developing organization from the perspectives of nurse managers, chief physicians, hospital directors and politicians. BACKGROUND: Increased responsibility in a changing health care system makes it important that nurses occupy advantageous positions so that they may safeguard and facilitate the development of their core area. METHODS:

Global environmental changes are topics of important societal concern and current scientific interest. These changes are driven by many different forcing and feedbacks occurring at various time and geographic scales and are largely influencing the various Earth systems. Despite the fact that the natural component of these changes has always occurred, today it's the anthropogenic component and its
This study sought to elucidate Swedish pediatric wards concerning the practice of informing children and their parents about clinical examinations and procedures. A semi-structured questionnaire was distributed to all 36 pediatric departments in Sweden, comprising of 83 wards. Fifty-eight (70%) of the wards responded. The results showed that 55 (95%) of the wards provided regular planned informati
This working paper analyses the mindset and driving forces of innovators in the agricultural sector. The key drivers and incentives are different in this group than for the innovators from academic institution. Therefor the interaction with risk capital providers becomes problematic.
Artros (i engelskt språkbruk ”osteoarthritis”, ibland ”osteoarthrosis”) är en sjukdom med sakta förlopp och ibland gradvis försämring. Sjukdomen kan leda till total förstöring av leden och behov av operation med ersättning av leden med konstgjort material. För de flesta patienter med artros blir kirurgisk behandling dock aldrig nödvändig, besvären kan behandlas bra på annat sätt.Artros är inte en
Analytical predictions of mechanical behaviour of fire-exposed steel structures are compared to experimental results obtained from three different research laboratories. Comparisons are made to axially free and restrained steel columns fire tested in Metz in France 1973-74, to simply supported steel beams fire tested in Germany and published in Stahlbau 1/1983 and to axially free and restrained st
The thermal decomposition of 1,2-dioxetane and the associated production of chemiluminescent products, model for a wide range of chemiluminescent reactions, has been studied at the multistate multiconfigurational second-order perturbation level of theory. This study is in qualitative and quantitative agreement with experimental observations with respect to the activation energy and the observed in
BACKGROUND: Previous studies have shown that atrial fibrillation of recent onset in man is based on a varying number of simultaneously present activation waves reentering either themselves or each other. In the present study, right atrial activation during chronic atrial fibrillation in man was studied. METHODS AND RESULTS: In 16 patients with chronic atrial fibrillation multiple epicardial record
Accurate description of the response function of X-ray detectors is important for quantitative PIXE analysis. For analytical description of low-energy tailing in PIXE spectra, the GUPIX approach was used, i.e. a combination of Hypermate type functions. The low-energy tailing parameters of a low-energy high purity germanium X-ray detector in the region 1.3-9.2 keV was determined by systematic fitti
Four juvenile Ross's gulls Rhodostethia rosea were trapped on the New Siberian Islands in the Laptev Sea in early August 1994, allowing data collection on body mass and morphometrics from a poorly known part of the species' annual cycle. The wings of juvenile birds were shorter than those previously reported for adults, but their bill length and tarsus length were similar. Their average body mass
Popular Abstract in Swedish Arkitekten Hans Westman var verksam i Skåne från 1932 till 1983. Hans rika och mångskiftande produktion har satt sin prägel på den moderna skånska arkitekturen, särskilt i Lund där han hade sitt arkitektkontor. Westmans arkitektur spänner över ett brett fält från bostadshus, offentliga byggnader, kraftverk till kyrkor och kloster. Flera verk är välkända, t ex radhusområThis thesis deals with the regional aspects of Swedish modernism exemplified by the architecture of Hans Westman (1905-1991). The main purpose of the dissertation has been to make a survey of what is perceived as particularly regional in Westman's buildings and if we can really talk about modern regional architecture. Modernism's breakthrough brought about the introduction of an architecture which
Popular Abstract in Swedish Syftet med studien har varit att, genom huvudsakligen kvalitativ beskrivning, studera narrativ sekvens, d v s berättelsen, i exolingvala samtal mellan infödd och icke infödd (svensktalande studenter) talare av franska. Den teoretiska ramen sträcker sig från textlingvistik (Revaz, Adam, Bronckart etc.) till konversationsanalys (Labov, Sacks, Norrick, Laforest, Kerbrat-OrThe aim of this study is to examine, through a mainly qualitative description, the narrative in exolingual conversations in French between non-native speakers (NNS) (Swedish students) and native speakers (NS). The theoretical frame ranges from text linguistics (Revaz, Adam, Bronckart etc.) to conversation analysis (Labov, Sacks, Norrick, Laforest, Kerbrat-Orecchioni, Bres, Norrby etc.). The study
Popular Abstract in Swedish Bakgrund - Glutenintolerans (celiaki) är en vanlig kronisk tunntarmssjukdom som drabbar 1% av befolkningen och beror på att man inte tål ämnet gluten som förekommer i vete, korn och råg. Celiaki är delvis ärftligt och förekommer i alla åldrar, men upptäcks framför allt hos barn. Intoleransen mot gluten orsakas av en immunologisk reaktion mot tunntarmens slemhinna som efCeliac disease is a prevalent small bowel disease in children caused by permanent intolerance against gliadin, which is the alcohol-soluble fraction of the cereal protein gluten in wheat, rye and barley. Celiac disease is characterized by an inflammatory infiltrate of CD4+ T lymphocytes in the intestinal mucosa leading to damage of villous structure and loss of absorptive surface. As a consequence
