Radiofrequency ablation is one of the common methods used to treat pain, movement or mood disorders. It bases on the electromagnetic energy provided to the selected tissue when an alternating current is applied. The resistive heating produced in this process provokes temperature rise in target tissue and generates lesion for intended therapeutic effects. However, in case when no tissue damage i...

The pulse-based charging method for battery cells has been recognized as a fast and efficient way to overcome the shortcoming of a slow charging time in distributed battery cells, which is regarded as a connection of cells such as the Internet of Things (IoT). The pulse frequency for controlling the battery charge duration is dynamically controlled within a certain range in order to inject the ...

We analyzed O2 pulse, the total volume of O2 consumed per heart beat, in guinea pigs at pressures from 10 to 60 atmospheres. Animals were placed in a hyperbaric chamber and breathed 2% O2 in either helium (heliox) or hydrogen (hydrox). Oxygen consumption rate (VO2) was measured by gas chromatographic analysis. Core temperature and heart rate were measured by using surgically implanted radiotele...

The three pulse photon echo peak shift technique was used to study solvation dynamics in acetonitrile ͑297 K͒, methanol ͑297 and 323 K͒, and ethylene glycol ͑297 and 397 K͒ utilizing the tricarbocyanine laser dye, IR144, as a probe. The spectral density, ␳͑␻͒, governing the solute-solvent interaction was obtained for each solvent and temperature through numerical fitting of the three pulse photon echo ...

Case 1.?Hindu male, aged 55. History of two days' illness. Removed from his house to hospital on 6th December, 1932. On admission his temperature was 103?F., pulse 135 of low volume and easily compressible and respirations 25. He had diarrhoea the previous day. Tongue?partially paralysed and dry; speech?not clear, delirious at night. There was a tender bubo in the right groin. The next morning ...

Application of ultrasonic energy at 20 kHz transesterification of vegetable oil is reported. Effects of 5 important variables i.e. pulse on (s), pulse off (s), reaction time (min), power (%) and oil volume (ml) at a constant alcohol to palm oil molar ratio (9:1) and initial reaction temperature of 35°C were studied. A central composite design (CCD) based on response surface technology (RSM) was...
