Abstract:
Objective: Rotation is a fundamental movement in Chinese dance, and many dancers are difficult to control the smoothness and stability of their movements during rotation, resulting in low completion rates. To better grasp the key points of rotational movements, this article started from a biomechanical perspective and studied the differences in completing rotational movements among dancers of different skill levels. Methods: Twenty dancers were divided into group A (high level) and group B (ordinary level). The dancers’ movements were recorded using two Casio cameras and analyzed using the APA

Abstract:
This paper reviews the role of the rotator cuff during two key phases of the pitching sequence and presents a training program for these muscles. The program uses a periodization design consisting of three stages, beginning with a high-resistance/low-repetition eccentric strengthening stage. This is followed by a low-resistance/high-repetition stage for training muscular endurance. The core exercises for these two stages are prone external rotation in the 90/90 position, prone horizontal abduction, side-lying D2 flexion pattern, supine internal rotation in the 90/90 position, prone elevation w

Abstract:
Correcting severe tooth rotations can be challenging. There are many ways to de-rotate teeth with fixed or removable appliances. Mechanically, the best and most effective way is one that produces a two-force couple system to rotate a tooth around its centre of rotation (longitudinal axis). The aim of this article was to introduce a simple and efficient technique using a closed coil to correct localised tooth rotations in the early alignment stage, utilising a simple two-force couple system. Furthermore, some of the biomechanical principles concerning de-rotation will be revisited.

Background: Motion of the two mutually immiscible liquids in hydrodynamic countercurrent chromatographic systems is speculated based on the observation of their behavior in a closed coiled tube rotating in unit gravity. Materials and Methods: The experiment revealed an up and down pattern of four stages of twophase volume ratio occupied at the head end of the coil according to the rotation speed. These two-phase behaviors are comprehensively explained on the bases of interplay between the unit gravity and centrifugal force generated by rotation of the coil.

To improve collision safety in robot–human collaborative applications, increasing attention has been paid to rotational variable stiffness actuators. A new rotational variable stiffness actuator, which works in two stages, is proposed for hybrid passive–active stiffness regulation. The passive stage is based on the motions of springs driven by the rack-and-pinion systems, elastically converting the shaft’s rotation into the inner shell rotation fixed to the internal gear of the active stage. The active stage is designed to achieve the movement of the pivot point located on the roller actuated

Because of the potential technical advantages, the contra-rotation technology has become a renewed interest in aviation and other applications. Contra-rotation increases efficiency in comparison with the single-rotor design, but this advantage is not fully harnessed. The axial spacing of two-stage contra-rotating blade rows has a significant impact on a contra-rotating fan/compressor. The results show that with a contra-rotation pattern, the strong unsteadiness of two-stage rotors is caused by the rotor-rotor interaction. The unsteadiness of rotor 1 is caused by the potential disturbance, and

Abstract A method for calculating a vibrating screen with two motor vibrators is proposed. The first part of the article is devoted to the issue of synchronizing the rotation of the rotors of both drives. Their opposite rotation creates a directed force passing through the center of gravity of the screen and perpendicular to the plane of the vibrator axes. The interaction of forces in this plane determines the phase mismatch of the rotation angles of the vibrators θ. An expression is obtained for determining the angle θ depending on the frequency of their rotation vibrators ω. It is shown that

Of special interest is the case of incompressible flow; when the fluid velocity is small compared to the speed of sound, the density may be treated as a constant.

This discrepancy has posed a serious challenge for planetary scientists to account satisfactorily for the formation and subsequent breakup of Pangea. Conventional orbital models of the Earth-Moon system cannot explain why Pangea formed on only one hemisphere of Earth, whereas this study’s proposed two-stage rotation model can provide a p

Abstract:
Abstract UREX+ is a solvent extraction process for partitioning spent fuel constituents to lead to safer and cheaper disposal of high-level waste. The procedure is based on an annular centrifugal stainless steel contactor developed for solvent extraction. During the centrifugal contactor operation there are two immiscible fluid phases, aqueous and organic, that move in opposite directions as they flow from stage to stage. These phases, which are mixed to accomplish separation and later separated, flow through two different centrifugal contactor regions called “mixing” and “separation” zones. I

Abstract:
Abstract The influence of rotation on the behavior of a two-dimensional rotating cylinder in flow was investigated by using the discrete vortex method combined with the 4th order Runge-Kutta method. There are three stages for rotational speed dependence of hydrodynamic force on a fixed rotating cylinder, the stage where lift force increases and drag force decreases, the stage where lift and drag forces increase in proportion to the square of rotation ratio, and the stage where lift and drag forces increase in proportion to rotation ratio. As a fixed rotating cylinder begins to rotate and the r

Abstract:
Often turbo-compressors exhibit the maximum efficiency condition very close to the stall limit, so that it would be highly interesting to have a deep comprehension of this phenomenon. Despite the large diffusion of the multi-stage centrifugal compressors in different fields of the technology, such as natural gas pipe-lines or chemical factories, at the best authors’ knowledge, to date no theoretical model exists for rotating stall in these machines. This paper deals with a model for simulating multi-stage centrifugal compressor flow pattern during rotating stall. The model is not able to captu

Abstract:
Aero compressor technology has seen a significant advancement during the last two decades. Research on Rotor-Stator stage has focused on improvements in the design as well as off-design performance. Work has also been carried out to improve the clearance losses, stage loading as well as the stability of the operation. In this connection, the work on end-bend rotor-stator and variable geometry stators is specially significant. These efforts have however, yielded marginal improvements as far as the capability of the stage to produce pressure rise and its through-flow capacity are concerned. The

Abstract:
Large standoff magnetometry is an emerging non-destructive magnetic test method, which is remote, passive, and non-contact. It is based on the inverse magnetostrictive effect and, therefore, has potential for detection of magnetic anomalies produced by elevated stresses in steel pipelines and ferromagnetic structures. Changes in the local pipeline stress state may arise due to corrosion, cracking, mechanical damage, ground movement (geohazards), or external loading.

As a new type of beam-column joint, external cover plate joints can be used in concrete-filled square steel tubular (CFSST) structures. To accurately analyze the mechanical characteristics of this novel joint during structural design, it is necessary to investigate the moment-rotation relationships. Based on the analysis of the force-transferring mechanism, the formulas to decide the initial rotation stiffness and ultimate bending moment are founded by using the component analysis method, while the finite element analysis results are also utilized to verify these formulas.
