Management of venous ulceration has evolved tremendously during the last 2 decades. There has been considerable progress in our understanding of the pathophysiology, hemodynamics, venous imaging, and therapeutic options for venous ulcers, including endovenous ablation, iliac vein stenting, and vein-valve repair techniques. Details of these procedures are described in this issue of Seminars. Wit...
The article discusses the possibility of improving design turbine a hydraulic drilling machine for wells in very hard rocks and at considerable depths (5000–12,000 m). analysis results studies on technical technological characteristics downhole motors showed that it is impossible to ensure stable operation due limitation operating temperature, while with an increase flow rate fluid, they do not...
The development of most unconventional oil and gas resources relies upon subsurface injection of very large volumes of fluids, which can induce earthquakes by activating slip on a nearby fault. During the last 5 years, accelerated oilfield fluid injection has led to a sharp increase in the rate of earthquakes in some parts of North America. In the central United States, most induced seismicity ...
Foetal and maternal rates of urea production and disposal in well-nourished and undernourished sheep
The Waste Isolation Pilot Plant (WIPP) has been developed by the U.S. Department of Energy for the geologic (deep underground) disposal of transuranic waste. Compliance with the containment requirements is demonstrated by means of performance assessment (PA). The term PA signifies an analysis that 1) identifies the features, processes and events (FEPs) that might affect the disposal system; 2) ...
