Expatriate Spaces, Ex-Soviet Places: Narratives of Americans Abroad in Turn-of-the-Millennium Post-C
The arrival of countless young North Americans into post-Cold War Central and Eastern Europe coincided with a U.S. recession, the collapse of Soviet influence in the former Warsaw Pact countries, and the consequential easing of travel restrictions. I show how overlooked narrative representations of sojourning Western twentysomethings carving out a space for themselves and negotiating their role in a newly internationalized place demonstrate a redefining of the American expat identity as a perfor

Efficient object based streaming framework for web-based education
An efficient moving object extraction algorithm suitable for real-time content-based multimedia streaming systems is proposed in this paper. A Motion Vector (MV) based object extraction is used to dynamically detect the objects. To utilize the bandwidth efficiently, the important object can be real time detected, encoded, and transmitted with higher quality and higher frame rate than those of background. In order to meet the real-time requirement, no computationally intensive operation is includ

In this activity, students observe a model of a waterwheel to investigate the transformations of energy involved in turning the blades of a hydro-turbine into work. Students work as engineers to create a model for a new waterwheel while considering resources, such as time and materials, in their design. Students also discuss and explore the characteristics of hydropower plants.

7 Immediate treatment of cardiovascular diseases

Treatment obviously depends on the severity of cardiovascular diseases at presentation and any safety considerations. Medications (pharmaceutical drugs) are available to treat many of the symptoms and slow the progression of cardiovascular diseases. Some are used for specific purposes, whereas others are useful for a range of cardiovascular diseases. In certain circumstances, individuals may not be able to take one type of medication and will be prescribed something else to serve the same fun
