An RTD can be fabricated using many different types of materials (such as III–V, type IV, II–VI semiconductor) and different types of resonant tunneling structures, such as the heavily doped p–n junction in Esaki diodes, double barrier, triple barrier, quantum well, or quantum wire.
Many RTD elements consist of a length of fine wire wrapped around a heat-resistant ceramic or glass core but other constructions are also used. The RTD wire is a pure material, typically platinum (Pt), nickel (Ni), or copper (Cu). The material has an accurate resistance/temperature relationship which is used to provide an indication of temperature.
RTD may refer to: Science and technology. Real-time data; Residence time distribution; Resonant-tunneling diode; Round-trip delay time, in telecommunications;
The tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, at the superior portion of the right ventricle.The function of the valve is to allow blood to flow from the right atrium to the right ventricle during diastole, and to close to prevent backflow (regurgitation) from the right ventricle into the right atrium during right ventricular ...
the first "pathway" has a slow conduction velocity but shorter refractory period; the second "pathway" has a faster conduction velocity but longer refractory period. [11] An important property that is unique to the AV node is decremental conduction, [12] in which the more frequently the node is stimulated the slower it conducts.
The velocity near the center of the pipe is higher than the fluids near the wall of the pipe. Thus, the velocity distribution of the reactants tends to be higher in the center and lower on the side. Consider fluid being pumped through an LFR at constant velocity from the inlet, and the concentration of the fluid is monitored at the outlet.
The symptoms of TR depend on its severity. Severe TR causes right-sided heart failure, with the development of ascites and peripheral edema. [1] In severe cases of right heart failure due to TR, venous congestion of the kidneys and liver may lead to cardiorenal syndrome (kidney failure secondary to heart failure) and cardiohepatic syndromes (liver failure secondary to heart failure ...
In transmitting antennas a second cause of power wastage is dielectric power losses of the electric field (displacement current) of the antenna passing through the earth to reach the ground wires. [15] For antennas near a half-wavelength high (180 electrical degrees [b]) the antenna has a voltage maximum near its base, which results in strong ...
