Torsion and gravitation: A new view
(World Scientific Publ Co Pte Ltd, 2004-05-01)
According to the teleparallel equivalent of general relativity, curvature and torsion are two equivalent ways of describing the same gravitational field. Though equivalent, they act differently: curvature yields a geometric ...
System to measure torsion modulus of polymers using the deformation energy method
(Assoc Brasil Polimeros, 2019-01-01)
This paper presents an alternative method to measure the torsion modulus, G, for samples of polymers. We constructed a measurement system with a force sensor (FS) and a rotational movement sensor (RMS) to obtain a relationship ...

Estimation of accidental torsion effects for seismic design of buildings
(1995)
A procedure is developed for including the effects of accidental torsion in seismic design of buildings. It has four steps. First, the ratio between the fundamental frequencies of uncoupled torsional and lateral motions ...
Shear force and torsion in reinforced concrete beam elements: theoretical analysis based on Brazilian Standard Code ABNT NBR 6118:2007Solicitações tangenciais em elementos lineares de concreto armado: análise teórica baseada na ABNT NBR 6118:2007
(IBRACON - Instituto Brasileiro do Concreto, 2012)
Reinforced concrete beam elements are submitted to applicable loads along their life cycle that cause shear and torsion. These elements may be subject to only shear, pure torsion or both, torsion and shear combined. The ...
Evaluation of code accidental‐torsion provisions from building records
(1992)
A procedure is presented for evaluating building‐code provisions for accidental torsion from analysis of earthquake‐induced motions of nominally symmetric‐plan buildings. This procedure is used to analyze the motions of ...

El síndrome escrotal agudo asociado a lesiones por fuerzas mecánicas como prevención de torsión testicular en pacientes menores de 18 años
(Universidad de Guayaquil. Facultad de Ciencias Médicas. Carrera de Medicina, 2020)
Antecedentes: Las torsiones testiculares afectan principalmente a la población adolescente. Dentro de los casos registrados en el Hospital General IESS Quevedo ser han reportado casos de pacientes que han acudo por un ...
Abelian torsion groups with a countably compact group topology
(ELSEVIER SCIENCE BV, 2010)
Comfort and Remus [W.W. Comfort, D. Remus, Abelian torsion groups with a pseudo-compact group topology, Forum Math. 6 (3) (1994) 323-337] characterized algebraically the Abelian torsion groups that admit a pseudocompact ...
