The centromeres of most higher eukaryotes are embedded within large regions of constitutive heterochromatin and consist of large quantities of highly repetitive DNA. Transposable elements are also found in these regions. However, a detailed mapping of such elements or other nonsatellite DNA embedded within the large blocks of centromeric repetitive DNA has not yet been made. The dipteran Chironomu
Northern Europe is in the forest zone, but wild megaherbivores have maintained grass-dominated vegetation here for the last 1.8 million years. Continuity of the grassland biome through glacialinterglacial cycles and connection to steppe vegetation has resulted in the evolution, immigration, and survival of a large number of grassland species. During the last millennia the effect of wild ungulates

Popular Abstract in Swedish Glatt muskulatur är nödvändig för funktionen hos de flesta inre organ såsom blodkärl, tarmar, gallblåsa, livmoder, urin och luftvägar. I artärer bildar glatta muskelceller ett cirkulärt lager, som skiljs från blodet genom ett tunt endotelcellslager. Muskelns främsta uppgift är att kontrollera blodkärlens diameter, och därmed blodflödet till de vävnader som de försörjer.Intracellular Ca2+ is a key regulator of vascular contractility, and thereby of blood perfusion and pressure. Ca2+ signals are essential also for cell migration, proliferation and regulation of numerous enzymes. Besides producing vascular contraction smooth muscle cells may also modulate to a synthetic phenotype and proliferate as an initial stage in the atherosclerotic proce
War criticism is not just expressed in journalistic and academic writing or in political speeches, but also in literature, such as in novels and short stories. This dissertation analyzes how war criticism is formulated in Swedish fiction written during the First World War (1914–1918). The study combines perspectives from rhetorical, narrative and sociological theory and focuses on how writers resi
