Abstract A small-scale test rig is developed to study the flow phenomena during off-design operations of a Francis turbine. The can be operated in open and closed loops for maximum head discharge 8 meters 0.055 m 3 /s. runner outlet diameter 200 mm rotates at 500 rpm. However, not model turbine as per IEC 600193. Therefore, repeatability parameters key establishing reliability measurement perfo...

For the Linac II, which supplies the accelerator chain at DESY with electrons and positrons, a new injection system is planned. It is supposed to ensure reliable operation and to avoid the beam loss of about 60% before the positron converter and the associated activation. The main components are a 6 A/100 kV triode gun, buncher and a dispersive section for energy collimation. The output energy ...

The retinoic acid-induced protein I (Rig-I/Ddx58), (RIG-I) initiates a signaling cascade that induces innate immune defences which is associated with the production of type I interferons (IFNs) and inflammatory cytokines to establish an antiviral state. Aberrant RIG-I signaling leads to inflammation, autoimmune diseases and cancer. However, the role of RIG-I in hepatocellular carcinoma (HCC) is...

(2010) Simulation and enhancement of a cardiovascular device test rig. Cardiovascular assist devices are tested in mock circulation loops (MCLs) prior to animal and clinical testing. These MCLs rely on characteristics such as pneumatic parameters to create pressure and flow, and pipe dimensions to replicate the resistance, compliance and fluid inertia of the natural cardiovascular system. A mat...
