Electrical storm: still a cryptogenic phenomenon?
The implantable cardioverter/defibrillator (ICD) has become the dominant therapeutic modality for the treatment of lifethreatening ventricular tachyarrhythmias. However, the ICD does not prevent the occurrence of ventricular tachycardia (VT) or ventricular fibrillation (VF). Repeated tachyarrhythmias occurring in a short period of time may therefore result in the delivery of multiple shocks. Th...
متن کاملelectrical charge transfer modeling (lightning) in cloud and its implementation in a one-dimensional prognostic cloud model
one of the most dazzling events in the atmosphere is lightning. during updrafts in the life cycle of cumulus clouds, collision of graupels and ice crystals in the presence of liquid water results in vertical separation of electrical charges and lightning. there are four types of lightening depending on the location of discharge. the first type is cloud-to-ground lightning or fork lightning that...
متن کامل"Thermal Charging" Phenomenon in Electrical Double Layer Capacitors.
Electrical double layer capacitors (EDLCs) are usually charged by applying a potential difference across the positive and negative electrodes. In this paper, we demonstrated that EDLCs can be charged by heating. An open circuit voltage of 80-300 mV has been observed by heating the supercapacitor to 65 °C. The charge generated at high temperature can be stored in the device after its returning t...
متن کاملElectrical Transport Phenomenon in Nanoparticle CuxCo1-xFe2-2yAl2yO4 Ferrite System
The polycrystalline aluminium substituted nanoparticle size copper cobalt ferrite samples CuxCo1-xFe2-2yAl2yO4 (where x= 0.0, 0.2, 0.4, 0.6, 0.8, 1.0; y = 0.05, 0.15 and 0.25) have been prepared by standard ceramic technique. The lattice constants of the phases are evaluated from x-ray diffraction data. The effects of Al on both AC and DC Electrical properties are studied. DC Electrical resisti...
متن کاملELECTRICAL SET-RESET PHENOMENON IN THALLIUM DOPED Ge-Te GLASSES SUITABLE FOR PHASE CHANGE MEMORY APPLICATIONS
Ge17Te83-xTlx (x = 2, 3, 6, 8, 10) glasses have been prepared by melt quenching method and their amorphous nature was confirmed by XRD spectra. I-V characteristics and repeatability of electrical switching were investigated for all the glasses in order to find out their suitability for phase change memory applications. A comparison has been given with Ge2Sb2Te5 the most commonly used material f...
