Saccular impact on ocular torsion
Brain Research Bulletin, 1996When someone is tilted laterally, the shear force on the maculae of the utriculus and the sacculus is described by the sine and the cosine of the angle of tilt, respectively. So both the sacculus and the utriculus are stimulated, but in the literature, ocular torsion is normally attributed to utricular function alone (and, thus, seen as a response to y-

Impact of DC-Link Voltage Control on Torsional Vibrations in Grid-Forming PMSG Wind Turbines [PDF]
IEEE Transactions on Energy ConversionThis paper explores the impact of dc-link voltage control (DVC) on the torsional vibration of grid-forming permanent magnet synchronous generator wind turbines (GFM-WTs), where the DVC is adopted by the machine-side converter.

Impact of Neighboring Chains on Torsional Defects in Oligothiophenes
The Journal of Physical Chemistry A, 2012Conjugated organic oligomers are central to the development of efficient organic electronic devices and organic photovoltaics. However, the torsional flexibility of many of these organic materials, in particular oligothiophenes, can adversely affect charge transfer properties.

Impact of seasonal variations on incidence and laterality of testicular torsion
International Journal of Biometeorology, 2023Nowadays, there is confusing evidence in the literature regarding the association between seasonal variations and events of testicular torsion (TT). We attempted to assess the correlation between seasonal variations, including season, ambient temperatures, and humidity levels to onset and laterality of testicular torsion.

Experimental Mechanics, 1972
A torsional-impact machine has been developed to investigate the dynamic behavior of metals at large strains and high strain rates. Two machines are described; the first was used to continuously monitor stress, strain profile and temperature profile during deformation; the second was designed specifically to investigate the thermal-instability strain ...

Journal of Vibration and Acoustics, 2016
Violent drillstring vibrations in a well should be suppressed to prevent premature failure of the drillstring parts and borehole wall and enhance the drilling process. This paper presents novel centralized impact dampers and torsional vibration dampers for lateral and torsional stick–slip vibration suppression which will function well in the harsh ...

Torsional impact of elastic spheres
Archive of Applied Mechanics, 1994The collision of two geometrically and materially similar elastic spheres, which are rotating around the common normal of their contact area, is analysed. The torsional rotation at the end of impact is obtained from numerical integration of the angular equation of motion and the contact law.

Proceedings of the Institution of Mechanical Engineers, 1955
In 1936, the author, working under Professor W. Mason, attempted to obtain a complete torque-time curve for impulsive torsional fracture and thus to obtain quantitative information on both yield and rupture phenomena. The forces were measured by piezo-electric methods and recorded photographically against a uniform time base.

Torsion in Quadrupeds and Its Impact on Mammalian Joints
Clinical Orthopaedics and Related Research, 1994Congenital and acquired torsion occur in the limbs of domestic animals. Congenital abnormalities are of clinical significance in foals; they are also seen in calves whose dams have ingested certain toxic plants that contain teratogenic agents. Acquired torsional deformities are most common in foals, but are also observed in adult horses, dogs, and ...
