We investigate a linearized tensor-tensor theory of gravity with torsion and a perturbed torsion wave solution is discovered in background Minkowski spacetime with zero torsion. Furthermore, gauge transformations of any perturbed tensor field are derived in general background non-Riemannian geometries. By calculating autoparallel deviations, both longitudinal and transverse polarizations of the...

The Meissner effect for superconductors in spacetimes with tor-sion is revisited.Two new physical interpretations are presented.The first considers the Landau-Ginzburg theory yields a new symmetry-breaking vacuum depending on torsion.In the second interpretation a gravitational Meissner torsional effect where when the Higgs field vanishes, torsion and electromagnetic fields need not vanish and ...

We obtain the solution that corresponds to a screwed superconducting cosmic string (SSCS) in the framework of a general scalar-tensor theory including torsion. We investigate the metric of the SSCS in Brans-Dicke theory with torsion and analyze the case without torsion. We show that in the case with torsion the space-time background presents other properties different from that in which torsion...

REASONS FOR PERFORMING STUDY Anecdotal speculation suggests that prognosis for survival of mares and foals following correction of uterine torsion has improved over the past 30 years. OBJECTIVES To determine statistically the outcome of uterine torsion according to duration of clinical signs, stage of gestation, parity, physical examination findings, method of correction, prognosis for surviv...

The aim of study was doppler ultrasonography-aided assessment of uterine blood fl ow in relation to duration and degree of uterine torsion in cattle. Fourteen dairy cattle with uterine torsion were detorted and fetal delivery was completed after detorsion. Six live and eight dead calves were delivered by cattle having torsion from lesser and prolonged duration, respectively. Whereas the dams of...

The changes of blood perfusion of contralateral testis after unilateral testicular torsion remain controversial. In this study, 28 New Zealand white male rabbits were randomly divided into five groups. Group A (n = 8), the control group, underwent a sham operation on the unilateral testis without inducing testicular torsion. In groups B, C, and D (n = 5 each), unilateral testicular torsion was ...

‎‎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: ...
