Preoperative diagnosis of a torsioned accessory spleen

Journal of Medical Ultrasound, 2021
We report a case of a 12-year-old boy with an accessory spleen torsion. He presented with left-sided abdominal pain after trauma. A 4 cm oval mass without contrast enhancement was detected on contrast-enhanced computed tomography (CT), and ultrasound (US)

Reinforced and prestressed concrete hollow beams under torsion

Journal of Civil Engineering and Management, 2014
Recently a new rational theoretical model for beams under torsion has been proposed. This model, called Softened Membrane Model for Torsion (SMMT), is able to predict well the global behaviour of reinforced and prestressed concrete solid beams under ...

Monotone-light factorisation systems and torsion theories [PDF]

, 2013
Given a torsion theory (Y,X) in an abelian category C, the reflector I from C to the torsion-free subcategory X induces a reflective factorisation system (E, M) on C. It was shown by A. Carboni, G.M. Kelly, G. Janelidze and R.

Minimal inclusions of torsion classes [PDF]

Algebraic Combinatorics, 2017
Let $\Lambda$ be a finite-dimensional associative algebra. The torsion classes of $mod\, \Lambda$ form a lattice under containment, denoted by $tors\, \Lambda$.

Absolute torsion and eta-invariant

, 1999
In a recent joint work with V. Turaev (cf. math.DG/9810114) we defined a new concept of combinatorial torsion which we called absolute torsion. Compared with the classical Reidemeister torsion it has the advantage of having a well-defined sign. Also, the

Stability in quadratic torsion theories [PDF]

, 2017
We revisit the definition and some of the characteristics of quadratic theories of gravity with torsion. We start from the most general Lagrangian density quadratic in the curvature and torsion tensors.

Discrete torsion [PDF]

Physical Review D, 2003
In this article we explain discrete torsion. Put simply, discrete torsion is the choice of orbifold group action on the B field. We derive the classification H^2(G, U(1)), we derive the twisted sector phases appearing in string loop partition functions, we derive M.

Design, Testing, and Sensitivity Analysis of a Torsional Cyclic Test Adapter

Machines
In this article, a torsional adapter is designed and evaluated through the comparison of analytical, numerical, and experimental tools. The adapter converts a conventional tension–compression test machine for cyclic loading to a modified application of ...

Acute torsion of the gallbladder:a report of two cases [PDF]

Journal of Kerman University of Medical Sciences, 1996
gallbladder torsion is a rare surgical emergency that can not be differentiated from acute cholecystitis.this condition occurs primarily in elderly women,although it may be encountered in early adulthood of both sexes.the anatomic background is based on ...

Delamination of multilayered non-linear elastic shafts in torsion [PDF]

FME Transactions, 2020
Delamination cracks in multilayered circular shafts loaded in torsion are analyzed in terms of the strain energy release rate. It is assumed that the material in each layer has non-linear mechanical behaviour that is treated by the Ramberg-Osgood ...
