Electric discharge machining is non conventional machining process used for machining of hard materials which cannot machined by conventional machining process. Electric discharge machining is an electro sparking method of metal working involving an electric erosion effect. A pulse discharge occurs in a small gap between the work piece and the electrode and removes the unwanted material from th...

Methanol decomposition using a catalytic reactor with electric discharges was investigated in the present study. The methanol conversion at 190 °C was 58.0%; however, the methanol conversion increased by 65.9% under the electric discharge. An electric discharge produces high energy electrons with sufficient energy to break a C-OH bond.

Carbon nanotubes (CNT) are produced from a rare variety of natural vein graphite (VG) distinctive to Sri Lanka using electric arc discharge. Electric arc-discharge produces both single walled and multi walled nanotubes. The products are characterized using high resolution electron microscopy and Raman spectroscopy for verification and validation. Keywords—CNT, vein graphite, arc discharge, SWCNT

Males and females of some mormyrid electric fishes generate electrical pulses that differ in waveform and duration. For one such species, testosterone or dihydrotestosterone induces females and immature males to produce the mature male electric organ discharge which is two times the duration of the female or immature discharge. Estradiol has only a weak effect. For a second species where males ...

In electric fish of the mormyrid family, an efference copy is present in the brain region that receives afferent input from ampullary electroreceptors. The efference copy is elicited by the motor command to fire the electric organ. Its effect is always opposite that the ampullary afferents responding to the electric organ discharge, and it changes to match variations in this afferent input. It ...

Abstract Self‐ignition during the explosive eruption of mud volcanoes can create flames that in some cases reach heights exceed hundreds meters. To study controls on electrical discharge natural mud, we performed laboratory experiments using a shock‐tube apparatus to simulate eruptions mud. We vary water content and proportions fine particles. measure electric within Faraday cage use high‐speed...
