‎‎In the category of Mordell curves (E_D:y^2=x^3+D) with nontrivial torsion groups we find curves of the generic rank two as quadratic twists of (E_1), ‎and of the generic rank at least two and at least three as cubic twists of (E_1). ‎Previous work‎, ‎in the category of Mordell curves with trivial torsion groups‎, ‎has found infinitely many elliptic curves with ...

ischemia-reperfusion injury is a possible cause of testicular damage and infertility after testicular torsion and detorsion. the purpose of this study was to evaluate the effect of ghrelin on testicular ischemia-reperfusion damage. a total of 30 adult male rats were selected for the study and divided randomly into 3 groups, each containing 10 rats. animals in the testicular torsion and ghrelin ...

abstract introduction: patellofemoral pain syndrome is a common problem in the knee joint, which comprise 20 to 40 percent of knee pain and 10 to 20 percent of subjects admitted in physiotherapy clinics. the aim of this study was to investigate the relationship between navicular drop and tibia torsion in active girl students with and without patellofemoral pain syndrome. materials and methods: ...

Torsion gelometry, a fundamental rheological test in which specimens are twisted until they fracture, was applied to several different cheese varieties to determine its suitability for measuring their textural properties. Fresh and aged Brick, Cheddar, Colby, Gouda, Havarti, Mozzarella, and Romano cheeses were subjected to torsion analysis, and the results were compared with those from small am...

An approximate numerical mthod is presented for analysis and determination of modal characteristics in straight, pretwisted non-unifom helicopter blades. The analysis considers the coupled flapwise bending (out of plane), chordwise bending (in plane), and torsion vibration of both rotating and non-rotating blades. The proposed method is based on the integral expansion of Green functions (struct...

We extend the deenition of analytic and Reidemeister torsion from closed compact Riemannian manifolds to compact Riemannian manifolds with bound

We report real space imaging measurements of inelastic Friedel oscillations. The inelastic electron tunneling spectroscopy, using scanning tunneling microscopy, around dimers of dichlorobenze adsorbates on Au(111) surface display clear spatial modulations that we attribute to inelastic scattering at the molecular sites caused by molecular vibrations. Due to local interactions between the adsorb...

Irregular buildings make up a large portion of  urban infrastructure. Presence of irregularities can be due to architectural and  user changes in building stories. Main objective of this article is evaluate seismic performance of structures with vertical irregularities. Seismic responses are obtained by enveloping peak inelastic responses resulting from pushover analyses according to provided p...

INTRODUCTION The purpose of this case series was to determine the sonographic features of neonatal ovarian torsion. MATERIALS AND METHODS Seven surgically proven cases of neonatal ovarian cysts were included in this retrospective study. The patients were divided into 2 groups, torsion and non-torsion. These 7 patients were evaluated for the clinical presentation, sonographic features, surgica...
