Lack of agreement between tonometric and gastric juice partial carbon dioxide tension

Our goal was to compare measurement of tonometered saline and gastric juice partial carbon dioxide tension (PCO2). In this prospective observational study, 112 pairs of measurements were simultaneously obtained under various hemodynamic conditions, in 15 critical care patients. Linear regression analysis showed a significant correlation between the two methods of measuring PCO2 (r 2 = 0.43; P < 0.0001). However, gastric juice PCO2 was systematically higher (mean difference 51 mmHg). The 95% limits of agreement were 315 mmHg and the dispersion increased as the values of PCO2 increased. Tonometric and gastric juice PCO2 cannot be used interchangeably. Gastric juice PCO2 measurement should be interpreted with caution.

This layer is a georeferenced raster image of the historic paper map entitled: Bacon's large-print map of the Transvaal and Orange Free State. It was published by G.W. Bacon & Co. ca. 1899. Scale [ca. 1:1,900,000]. Covers also Swaziland, Lesotho, and portions of Botswana, Zimbabwe, and Mozambique.The image inside the map neatline is georeferenced to the surface of the earth and fit to the Africa Sinusoidal projected coordinate system. All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows features such as drainage, cities and other human settlements, territorial and administrative boundaries, roads, railroads, shoreline features, and more. Relief shown by shading and spot heights. Includes also insets: "Map showing the routes from England and India to South Africa", "Environs of Cape Town", "Lorenço Marquez [and vicinity]", 'South Africa" and "Durban and Port Natal".This layer is part of a selection of digitally scanned and georeferenced historic maps from the Harvard Map Collection. These maps typically portray both natural and manmade features. The selection represents a range of originators, ground condition dates, scales, and map purposes.

The Revolution that never was. Five years of 'Orange' Ukraine. OSW Point of View (Policy Brief), November 2009

On the fifth anniversary of the Orange Revolution and in the final period of the presidency of Viktor Yushchenko, who then embodied the hopes for state reform, a tentative assessment of the situation in Ukraine is appropriate. Did the revolutionary social upheaval bear revolutionary fruit? Have democratic mechanisms strengthened? Has the post-Soviet oligarchic state model been overcome? Has media freedom expanded? Has there been any progress with regard to economic transformation? Has integration with the European structures materialised? Five years on, what remains of the hopes of millions of Ukrainians and of the goodwill of the international community?
