The development and upgrade of test installations, instrumentation and the data acquisition system of an existing turbofan engine test rig are described for an experimental program which was planned and initiated to investigate the transient unsteady operation of gas turbine engines with an emphasis on compressor operation. The objective of the program was to examine aerodynamic instabilities s...

In his article "Literary Geography and Comparative Literature" César Domínguez analyzes the relevance of political and linguistic frameworks for comparative literary historiography in the context of the European Union. Domínguez's discussion is based on the notion of geoculture whose theorization from Immanuel Wallerstein's perspective presents paradigms of interest to comparative literature. T...

Using a new data set, we estimate the magnitude of the incumbency advantage in direct primary elections between 1910 to 2000. We ̄nd that the incumbency advantage, as estimated by the sophomore surge, was above 5 percentage points in primary elections even in the ̄rst decades of the twentieth century. The sophomore surge in primary elections grew to approximately 15 percentage points by the end...

Storm surge is dependent on wind direction, with maximum surge heights occurring when strong winds blow onshore. It is less obvious what happens when a port city is situated at the end of a long narrow gulf, like Venice at the northwestern end of the Adriatic Sea. Does the narrow marine approach to the port city limit the dangerous wind direction to a span of only a few degrees? This modeling s...

There are variations in the onset of cardiovascular events. As diurnal variation, most studies have shown an increased incidence of acute cardiovascular events such as acute myocardial infarction, sudden cardiac death, and stroke in the morning.1 In addition, weekly and seasonal variations in the cardiovascular events have also been reported.2 These variations may be closely associated with amb...
