Implications of the social consequences of global information technology outsourcing in the USA

The transformation and movement of work opportunities is not a new phenomenon. This has been the norm in many industries, such as manufacturing, semi-conductors, clothing, etc. This is the first time, however, that so-called knowledge intensive work areas would be hit en masse, instead of low waged jobs. This has and will have a large impact on individuals, firms, and society. From a global perspe

DNA in centromeres of Chironomus pallidivittatus

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

Biodiversity in temperate European grasslands: origin and conservation.

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

Dynamics of Ca2 handling in vascular smooth muscle

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
