In this paper firt of all we introduce a generalization of torsion freeness of acts over monoids, called -torsion freeness. Then in section 1 of results we give some general properties and in sections 2, 3 and 4 we give a characterization of monoids for which this property of their right Rees factor, cyclic and acts in general  implies some other properties, respectively.

During the development of a new vehicle, the vehicle is usually tested to determine both its static torsional and bending stiffness, and its dynamic torsional and bending modes. This paper discusses a method for determining both static and dynamic properties from the modal analysis test. Such a connection between static stiffness and dynamic modes would be useful for three reasons: (1) the rela...

In this paper, we demonstrate 3D-printed 1-DOF (one torsional axis; 1 degree of freedom) optical scanners with large mirror areas (up to 20 × mm2). Each device consists an aluminum-coated square silicon substrate serving as the mirror, two miniature permanent magnets, electromagnet, and a structure including frame, torsion springs, base. One can reach static half scan angle 14.8 deg., i.e., ful...

In the present work, we {study} static spherically symmetric solutions representing wormhole configurations in Poincar\`{e} gauge theory ({{\sf PGT}}). The gravitational sector of Lagrangian is chosen as a subclass {\sf PGT} Lagrangians for which, spin-$0^+$ only propagating torsion mode. spacetime has dynamical nature even absence intrinsic angular momentum (spin) matter, hence, {torsion can p...

Abstract The simulation was carried out using the computional fluid dynamics method to find and read flow pattern in reactor. Simulations were implemented nine reactors, which every reactor have 12 helical type static mixer elements. elements are twisted 180°, between glued at an angle of 90°. Also performed two scenarios on modification torsion elements, namely 225° 270° . Based velocity visco...

Acute scrotal swelling is an urgent urologic condition, and its failure in diagnosis is "one of the litigious issues in urologic practice. "1-2 Although acute scrotal pain is due to spermatic cord torsion in 25-35% of cases, the urologist should either rule it out or treat it immediately. 2 We operated a case of acute scrotal edema in a two-day-old boy who had, according to clinical results...

Perinatal testicular torsion (PTT) is a rare entity. The management of PTT is controversial, due to the low viability of the testis and the possibility of bilateral torsion. This is a review of our experience with six cases of PTT, highlighting diagnostic and therapeutic difficulties of this condition.

Background and Aim: Ovarian torsion is one of the rare causes of emergency surgeries during pregnancy. Heterotopic pregnancy is a rare type of pregnancy characterized by embryo implantation in two different locations. occurence of these two complications at the same time is a very rare condition. In this study, we present a rare case of heterotopic pregnancy accompanied by ovarian torsion. Pat...
