Ovarian torsion (adnexal torsion) is an uncommon disorder in pediatrics and should be considered as a differential diagnosis of abdominal pain in preteen girls. Almost 70% of ovarian torsions are seen in young girls older than 20 years, but it could also occur in preteen girls. Sonography is one of the most useful methods to diagnose ovarian torsion. In pediatrics, ovarian torsion should ...
In this work we introduce a new concept, namely, τ s τs -extending modules (rings) which is torsion-theoretic analogues of extending and then extend many results from to concept. For instance show that for any ring R with unit, if $_{R}R$ purely only every cyclic -nonsingular -module flat. Also, make classification the direct sums rings be -extending.
The title compound, C28H22N2O8, possesses crystallographically imposed twofold symmetry, with the two central carbon atoms of the naphthalene unit lying on the rotation axis. The two benzoyl groups in the mol-ecule are twisted away from the attached naphthalene unit with a C-C-C=O torsion angle of 49.05 (15)° between the naphthalene unit and the carbonyl group. The dihedral angle between the na...
Abstract Testicular torsion is a medical emergency appearing at any age, the prevalence of which in the neonatal period comprises 10% of the whole cases occurring at any point in life. Among all the cases being diagnosed at birth, 70% has occurred in the prenatal period and 30% in the neonatal period. Generally, the most common symptoms of testicular torsion during postnatal period includ...

An R-module M is called Almost uniserial module, if any two non-isomorphic submodules of M are linearly ordered by inclusion. In this paper, we investigate some properties of Almost uniserial modules. We show that every finitely generated Almost uniserial module over a Noetherian ring, is torsion or torsionfree. Also the construction of a torsion Almost uniserial modules whose first nonzero Fit...
conclusions these findings emphasize the potential clinical benefits of therapeutic procedures such as cardiac resynchronization therapy (crt) or apex-sparing volume-reduction surgery in dcm. a better definition of the role and implications of reverse apical torsion in dcm and its importance and effectiveness in making therapeutic decisions like crt implantation requires further studies. case p...
In this article, the Second Strain Gradient (SSG) theory proposed by Mindlin is used within a Wave Finite Element Method (WFEM) framework for dynamic analysis of one-dimensional Euler–Bernoulli bending beam and torsional bar. Firstly, strong forms continuum models including governing equations boundary conditions torsion cases, respectively, are derived using Hamilton’s principle. New “non-loca...
The nucleosome, the fundamental packing unit of chromatin, has a distinct chirality: 147 bp of DNA are wrapped around the core histones in a left-handed, negative superhelix. It has been suggested that this chirality has functional significance, particularly in the context of the cellular processes that generate DNA supercoiling, such as transcription and replication. However, the impact of tor...
The asymmetric unit of the title hydrate, C(9)H(8)ClN(3)O·0.5H(2)O, comprises two independent 1,2,3-triazole mol-ecules and a water mol-ecule of crystallization. The dihedral angles between the six- and five-membered rings in the 1,2,3-triazole mol-ecules are 12.71 (19) and 17.3 (2)°. The most significant different between them is found in the relative orientations of the terminal CH(2)OH group...
