because of the everyday use of power generators in iraq, which exist in residential neighborhoods, it is necessary to study the impact on soils and plants surrounding areas of those generators. lead is one the most heavy metals released especially, as a result of the combustion of diesel fuel during operation of the powered generators. however, a study was conducted to investigate the lead conc...

External, miniaturized, transistorized, patientportable, battery-powered, pulse generators with exteriorized electrodes for temporary transvenous endocardial or transthoracic myocardial pacing. 3. Console batteryor AC-powered cardiovertors, defibrillators, or monitors with high-current e...

Background: In the aftermath of the Great East Japan Earthquake, most of the areas in Yamagata prefecture experienced a serious power failure lasting for approximately 24 hours. A number of households were subsequently poisoned with carbon monoxide (CO) due to various causes. In this study, we conducted a survey of CO poisoning during the disaster. Methods: A questionnaire regarding CO poisonin...

This paper reviews the state-of-the art in vibration energy harvesting for wireless, self-powered microsystems. Vibration-powered generators are typically, although not exclusively, inertial spring and mass systems. The characteristic equations for inertial-based generators are presented, along with the specific damping equations that relate to the three main transduction mechanisms employed to...

BACKGROUND Carbon monoxide (CO) poisoning is common after major storms because of loss of electrical power and use of alternate fuel sources for heat and electricity. In past epidemics of hurricane-related CO poisoning, the source has typically been gasoline-powered electrical generators. Although it is typically believed that generators were used to power air conditioning and refrigeration, th...

This paper compares the performances of a vibrationpowered electrical generators using PZT piezoelectric ceramic associated to two different power conditioning circuits. A new approach of the piezoelectric power conversion based on a nonlinear voltage processing is presented and implemented with a particular power conditioning circuit topology. Theoretical predictions and experimental results s...

Compact, high-gain magnetic flux compressors (FCGs) are convenient sources of substantial energy for plasma-physics and electron-beam-physics experiments, but the need for highvoltage, fast-rising pulses is difficult to meet directly with conventional generators. While a variety of novel concepts employing simultaneous, axially-detonated explosive systems are under development, power-conditioni...
