In math.GT/0510607, a conjecture is suggested by J. Dubois and R. Kashaev. It is that the differential coefficient of the abelian Reidemeister torsion of a knot exterior at a bifurcation point of the SL(2, C)-representation variety of its knot group corresponds a limit value of the non-abelian twisted Reidemeister torsion of the knot exterior. We shall prove this conjecture in the present paper.

introduction left ventricular (lv) twist is believed to store potential energy and plays an important role in generating diastolic suction. recent advances in echocardiography techniques have allowed quantification of lv twist. the aim of the present study was to compare lv twist and torsion in healthy human subjects determined by velocity vector imaging (vvi) and tissue doppler imaging (tdi) a...

Holographic methods are utilized to examine deviations from classical elasticity in a cellular solid, polymethacrylamide closed cell foam. A square cross section bar is subjected to static torsional deformation. The warp deformation is observed to be less in a foam bar than in a homogeneous polymeric bar used as a control. The homogeneous bar obeys the predictions of classical elasticity. Behav...

Introduction: The aim was to investigate the protective effect of the Syzygium aromaticum extract on damaged tissues and the oxidative stress after testicular torsion. Methods: Rats were randomly divided into a control group subjected to a sham procedure and three treatment groups comprising testicular torsion followed by detorsion (TD), testicular torsion detorsion followed by the tre...

background : as recently some reported is investigated about relation between cold weather and testicular torsion (tt), so we decided to evaluate this hypothesis risk factor for testicular torsion in our children’s hospital. objectives : the aim of this study is to evaluate the relation between cold weather and testicular torsion in children. methods: from january 2011 todecember 2015 totally h...

abstract   background: tibial torsion is one of the torsion density which rotating in the longitudes axis of the leg. to measure this deformity, different methods such as radiographic or clinical methods were presented and introduced. methods: in this quasi-experimental study, 30 male athletes were selected randomly. their tibial torsion angle was measured using ct scan, lavand, lokomso, foot p...

the testicular torsion which is typically seen in prepuberty is very rare in the early neonatal period; prenatal diagnosis is difficult. herein, we report a five day-old male neonate with swelling and erythema of the right scrotum.  following doppler ultrasound suggestive of testicular torsion, surgical exploration was undertaken. there was gangrene of the right testis with discoloration and ne...

anandamide is an endogenous ligand for cannabinoid receptors and has endothelial protective effect against ischemic preconditioning. the purpose of this study was to investigate the effects of cannabinoids on reperfusion injury due to testicular torsion-detorsion (t/d). a total of 36 adult male sprague-dawley rats were divided into 6 groups. testicular ischemia was achieved by twisting the righ...

We identify some classes $$\mathcal {C}$$ of mixed groups such that if $$G\in \mathcal has the cancellation property then Walk-endomorphism ring G unit lifting property. In particular, is a self-small group torsion-free rank at most 4 with it decomposition $$G=F\oplus H$$ F free and H

isolated fallopian tube torsion is rare and often difficult to diagnose. definitive diagnosis is always made at laparoscopic or via laparotomy exploration performed for suspected ovarian torsion. early diagnosis and conservative laparoscopic treatment especially in a reproductive age woman is warranted as a means of preserving fallopian tube integrity and maintaining fertility. here, we describ...
