Popular Abstract in Swedish Kambrium är en tidsperiod i jordens historia som sträckte sig från 542 till 488 miljoner år sedan. Denna period kan vidare delas in i tre epoker: tidigkambrium, mellankambrium och furongian. I kambriums inledningsskede ägde en intensiv och snabb utveckling av livet rum och det var under denna tid som i stort sett alla kända djurstammar utvecklades. Denna viktiga händelsThis thesis is based on studies of upper middle Cambrian through Furongian strata in Scandinavia with focus on trilobite biostratigraphy, taxonomy, paleoecology, and intercontinental correlation. The material studied derives mainly from Västergötland and Scania, southern Sweden. Three new trilobite species are described: Macropyge (Promacropyge) scandinavica, Elkanaspis kinnekullensis, and Parabol

The HELLP (Hemolysis, Elevated Liver enzyme, and Low Platelet) syndrome requires close monitoring of rapid changes in hemostasis. A bedside viscoelastic test--Sonoclot--was used together with coagulation, liver and hemolysis laboratory analyses in three parturients with the HELLP syndrome up to 10 days postpartum. Principal component analysis (PCA) was used to reduce the dimensionality of this mul

The report deals with the problems which may be caused by internal additional insulation of an existing building component. Problems treated in this report are heat losses through and surface condensation at thermal bridges, condensation in the building components, stresses due to temperature and moisture content variations and possibly frost damage in facade materials. After internal insulation

The present doctoral dissertation discusses Japanese office employees' psychological reactions to their underground work environment. Studies I and III were methodological in nature and aimed at developing and validating instruments to be used in the empirical studies. The first empirical analysis (Study II) examined office employees' perception of the importance of windows, the lighting condition

Interleukin-1 (IL-1) is a major mediator of inflammation that exerts its biological activities through the IL-1 type I receptor (IL-1RI). The body weights of IL-1RI(-/-) mice of both sexes started to deviate from those of wild-type mice at 5-6 months of age and were 20% higher at 9 months of age. Visceral and subcutaneous fat mass, measured by dual-energy X-ray absorptiometry and magnetic resonanc

Rheumatoid arthritis is a disease of unknown aetiology. Twin studies indicate the importance of genetic as well as environmental factors. 1 In terms of environmental factors, few risk factors are well established, and, in practice, rheumatoid arthritis cannot be attributed to any specific exposure. 2 Descriptive studies imply a birth cohort effect in the incidence of rheumatoid arthritis. 3 4 We a

Single film examinations (iodine and/or barium) were reviewed in 28 patients who had undergone surgery on the cricopharyngeal muscle due to Zenker diverticula (24 patients), cricopharyngeal muscle incoordination (3 patients) and pharyngoesophageal web (one patient). All patients had had a myotomy which included the cricopharyngeal muscle and up to 3 cm of the cervical esophagus. Lateral and anteri

The somatic cell count (SCC) in bovine milk is an indicator of udder health and milk quality. Individual cell populations, i.e., macrophages, lymphocytes and polymorphonuclear neutrophils, were identified and their relationship to milk components such as acute-phase proteins (serum amyloid A (SAA) and alpha(1)-acid glycoprotein), lactic acid and lactoferrin (LF), as well as protein, fat and lactos

Beim Fahrradfahren arbeitet der Mensch als Regler. Das wird beim Balancieren des Fahrrades besonders offensichtlich, denn das Fahrrad ist instabil. In diesem Beitrag wird untersucht, unter welchen Bedingungen es möglich ist, das Fahrrad mit einem so einfachen Reglergesetz zu balancieren, dass Menschen dieses Reglergesetz ohne Mühe realisieren können. Dabei wird nicht nur die jedem Radfahrer bekann

Low body mass index (BMI) is a well-documented risk factor for future fracture. The aim of this study was to quantify this effect and to explore the association of BMI with fracture risk in relation to age, gender and bone mineral density (BMD) from an international perspective using worldwide data. We studied individual participant data from almost 60,000 men and women from 12 prospective populat
