Drug self-administration and ultrasonic vocalizations (USV) are used as behavioral assessments in animal research, but rarely in combination. The purpose of this article is to describe the advantages of recording USVs during drug self-administration procedures to assess affective responses to drug experience.

Passive filters are utilized to shape the frequency spectrum of signals across a diverse array of applications. These filters, using only passive elements like resistors (R), inductors (L), and capacitors (C), are capable of selectively allowing or blocking certain frequency ranges without the need for external power sources. Low-Pass Filters Low-pass filters are designed to transmit signals with frequencies lower than the cutoff frequency, ωc, and attenuate those above it. The cutoff frequency...

Ammonia emissions are a major threat to the environment by eutrophication, soil acidification and fine particle formation and stem mainly from agricultural sources. This method allows ammonia loss measurements in replicated field trials enabling statistical analysis of emissions and of relationships between crop development and emissions.
FAQs
Acoustic streaming improves cleaning by creating vigorous fluid movement around the irrigant inside the prepared canal. This circulation helps carry the solution into areas where direct instrument contact is limited, while disrupting debris, tissue remnants, and microbial biofilms. The result is enhanced irrigant action in irregular canal spaces.
Keeping the ultrasonic file or tip from intentionally touching the canal walls allows it to work through fluid movement rather than direct scraping. This noncontact arrangement is important because the added cleaning effect comes from acoustic streaming and possible cavitation, extending irrigant activity into spaces an instrument may not reach directly.
Cavitation is identified as a possible companion to acoustic streaming, rather than a guaranteed effect in every use. When it occurs, it may contribute to disruption of material within the irrigant-filled canal alongside fluid circulation. This matters because ultrasonic energy can mobilize the solution around anatomy that direct instrumentation does not contact.
The technique is applied within a prepared root canal containing an irrigating solution. A small oscillating ultrasonic file or tip is positioned in the canal without intentionally contacting its walls, and ultrasonic energy is used to enhance irrigant movement. Appropriate irrigants and clinical protocols remain important for supporting the intended cleaning and disinfection effects.
Irregular spaces, fins, and lateral canals may benefit because instruments may not reach them directly. Enhanced circulation moves the irrigating solution through these less accessible regions, where it can help disrupt debris, tissue remnants, and microbial biofilms. This makes the approach especially relevant when canal anatomy limits direct mechanical cleaning.
Passive Ultrasonic Irrigation supports root canal disinfection by improving the action and distribution of the irrigating solution. Its enhanced fluid movement may also improve treatment outcomes by addressing debris, tissue remnants, and microbial biofilms in areas that direct instruments cannot readily access. The method therefore complements canal preparation rather than replacing it.
