The microcalorimeter technique continues to be the key technique for the realization of the primary power standards in the high frequency, because at the state of the art, only it allows tracing the power standards to the direct current standard, that is a SI quantity. This traceability is obtained through the determination of the effective efficiency, usually indicated by € ηe, of a power sens...

Process physics understanding, real time monitoring, and control of various manufacturing processes, such as battery manufacturing, are crucial for product quality assurance. While ultrasonic welding has been used for joining batteries in electric vehicles (EVs), the welding physics, and process attributes, such as the heat generation and heat flow during the joining process, is still not well ...

The effect of various wave lengths of visible light in the stimulation of single visual sense cells has been studied by means of the single fiber preparation from the eye of Limulus. Oscillographic records were made of the impulse discharge in a single optic nerve fiber in response to stimulation of the attached sense cell by lights of different wave lengths. Wratten monochromatic filters suppl...

This thesis describes three techniques for the characterization of living cells using micro-electro-mechanical systems (MEMS) based devices. The study of cellular function and structure is essential for bioprocess control, disease diagnosis, patient treatment and drug discovery. Microsystem technology enables characterization of very small samples, minimal use of expensive reagents, testing of ...

To prevent dissection injury when cutting strip preparations from human left ventricular papillary muscle tissue, dissections were carried out with 2,3-butanedione monoxime (30 mM) added to Krebs-Ringer solution and followed by washout with normal solution. Eleven muscle strip preparations were dissected from left ventricular papillary muscle tissue of five patients undergoing mitral valve repl...
