Flipper coil closure of patent ductus arteriosus [PDF]
, 2007 Transcatheter closure of patent ductus arteriosus is now a well established therapeutic option. In this paper, we illustrate step by step the technique of Flipper coil closure of small (

Relationship between voice coil fill factor and loudspeaker efficiency [PDF]
, 2016 In modern audio systems, utilizing switch-mode amplifiers, the total efficiency is dominated by the rather poor efficiency of the loudspeaker. For decades voice coils have been designed so that nominal resistances of 3 to 8 Ω are obtained, despite modern

Biochemistry and Molecular Biology Education, Volume 53, Issue 2, Page 209-217, March/April 2025.Abstract We created a novel laboratory experience where undergraduate students explore the techniques used to study protein misfolding, unfolding, and aggregation. Despite the importance of protein misfolding and aggregation diseases, protein unfolding is not typically explored in undergraduate biochemistry laboratory classes.

Temperature prediction of the voice coil of a moving coil loudspeaker by computer simulation.
Journal of the Acoustical Society of Japan (E), 2000 In most cases the increase in voice coil temperature is the major cause for speaker failure.Several techniques have been developed to keep voice coil at room temperature under high power inputs.It is a known fact that rise in temperature causes a rise in the total resistance of the voice coil.Providing negative impedance at the amplifier output to ...

Measuring Voice Coil Temperature using Ultrasonic Pilot Tones
, 2022 Measuring the voice coil temperature of speakers during audio playback is useful for optimizing thermal design and preventing overheating. The established DC method uses a constant current to measure resistance and determine temperature.

Perceptual auditory aftereffects on voice identity using brief vowel stimuli [PDF]
, 2012 Humans can identify individuals from their voice, suggesting the existence of a perceptual representation of voice identity. We used perceptual aftereffects--shifts in perceived stimulus quality after brief exposure to a repeated adaptor stimulus--to ...

Business Strategy and the Environment, EarlyView.ABSTRACT The lag in embedding leaders' decarbonization competences into sunset industry businesses (oil, gas, and petroleum), particularly in Middle Eastern hydrocarbon economies, poses an existential environmental and institutional challenge. In many such contexts, leaders' decarbonization competences remain subordinated to resource utilization and ...
