An 8-electrode capacitance tomography (ECT) sensor was built and used to measure moisture content (MC) and mass flow of pine chip flows. The device was capable of directly measuring total water quantity in a sample but was sensitive to both dry matter and moisture, and therefore required a second measurement of mass flow to calculate MC. Two means of calculating the mass flow were used: the fir...

In the measurement of mutual capacitance between electrodes both the coupling and the leakage effect contribute to the measurement result whereas the leakage mode is dominant in the selfcapacitance mode. While the coupling effect is mainly defined by the geometry and material distribution close to the electrodes, the root cause or modulation of the leakage effect may be far away from the electr...

Summary) Among tomography techniques for process control and visualization, electrical based tomography systems are the most prominent due to their low construction cost, high speed, and safety. The development of electrical tomography has been mainly focused on permittivity, conductivity, or permeability imaging. Successful implementation of tomography systems depends on the sensor configurati...

The article presents a new concept for monitoring industrial tank reactors. presented allows faster and more reliable of processes, which increases their reliability reduces operating costs. innovative method is based on electrical tomography. At the same time, it non-invasive enables imaging phase changes inside tanks filled with liquid. In particular, hybrid tomograph can detect gas bubbles c...

Electroconvulsive therapy (ECT) induces abrupt changes in systemic and cerebral haemodynamics that are problematical for patients with cardiovascular or cerebrovascular complications. Although there are no reports of ECT causing rupture of a cerebral aneurysm, excessive haemodynamic changes in such patients must be avoided. Short-acting -adrenoceptorblocking agents, e.g. esmolol, are suitable t...

ectopic cervical thymus (ect) is an essentially benign condition that is identified during the development of the thymus, and is rare among the adult population. thymic hyperplasia is another thymus-associated condition, which is known to occur secondary to hyperthyroidism. a 39-year-old woman with hyperthyroidism presented with an enlarging submandibular mass, which was diagnosed as a benign h...
