Controllable pitch-bending effects in the accordion playing
The Journal of the Acoustical Society of America, 2008The accordion employs reeds in which the tongue is mounted outside the reed frame in such a way that sounding is normally possible only on one direction of airflow. Under normal operating conditions the reeds behave as blown-closed. Pitch bending technique allows players to make a controllable glide, non tempered glissando, from one pitch to another ...

Accordion effect during carotid artery stenting
Neuroradiology, 2007The term "accordion effect" is used to describe a mechanical distortion of tortuous arteries mimicking spasm or dissection. This phenomenon has been reported in patients undergoing percutaneous coronary intervention. To our knowledge, this is the first documentation of the accordion effect during carotid artery intervention.Two patients who developed ...

The Journal of Ethics, 2006
In "Action and Responsibility,'' Joel Feinberg pointed to an important idea to which he gave the label "the accordion effect.'' Feinberg's discussion of this idea is of interest on its own, but it is also of interest because of its interaction with his critique, in his "Causing Voluntary Actions,'' of a much discussed view of H. L. A. Hart and A.

Accordion effect: A red herring during percutaneous angioplasty of arteriovenous dialysis access
The Journal of Vascular Access, 2020Accordion or concertina effect is the angiographic appearance of pseudostenosis caused by interaction of a stiff guidewire with a tortuous vessel during endovascular procedures. This phenomenon may often mislead the interventionist into performing unnecessary and potentially harmful procedures in a bid to treat the ‘stenotic’ lesion. The resolution of ‘

Simulation of Accordion Effect of I-Girder with Corrugated Steel Webs
Applied Mechanics and Materials, 2013The axial stiffness of the corrugated steel plate is negligible by nature of unique geometric characteristics of the plate called as the accordion effect. This unique effect results in high efficiency on post-tensioning. Thus, corrugated steel plate is very suitable for a web of PC-box girder.

Simulation of accordion effect in corrugated steel web with concrete flanges
Computers and Structures, 2004Abstract Prestressed concrete girders with corrugated steel webs are one of the promising concrete–steel hybrid structures applied to highway bridges. Prestress can be efficiently introduced into the concrete flanges due to the so-called “accordion effect” of the corrugated web.

Catheterization and Cardiovascular Diagnosis, 1991
AbstractCoronary spasm and intimal dissection are well‐known complications of coronary angioplasty with potentially serious consequences. Their treatments are different and need to be instituted quickly to prevent vessel closure. We report two cases of mechanical deformation caused by the angioplasty hardware masquerading as dissection or spasm during ...

[Effect of "accordion" technique on bone consolidation during distraction osteogenesis].
Zhongguo xiu fu chong jian wai ke za zhi = Zhongguo xiufu chongjian waike zazhi = Chinese journal of reparative and reconstructive surgery, 2018To investigate the effect, right timing, and mechanism of "accordion" technique on bone regeneration in rat distraction osteogenesis model.Fifty-four 12-week-old male Sprague Dawley rats underwent right tibial distraction osteogenesis procedure. After a 5-day latency, the distraction was performed for 7 days followed by 6-week consolidation.

Tortuous internal mammary artery angioplasty: accordion effect with limitation of flow.
The Journal of invasive cardiology, 2005Mechanical straightening of a tortuous vessel during angioplasty has been well described. It can be mistaken for thrombus, dissection or spasm. This report presents a case in which straightening of vessel due to stiff guide wire results in accordion effect and flow limitation.
