Symbolic Representations of the Pendulum Movement (in Polish and East Slavic Folklore Traditional Culture) This article is devoted to symbolic representation pendulum movement, such as rocking, swaying swinging. The research covered folklore, ethnographic linguistic material. analysis aims reach conceptual basis motion developed from physical experience movement related events magical practices...

Differing from the traditional method of treating the motion of ring valve-plates as translational or inclined motions of rigid bodies, this paper originated from the concept on deformations involved in the motion processes. Emphasis of research is centered on flexural warping vibrations during opening and closing. Mechanical modelling and mathematical interpretions of plate motion with various...

AIMS Current attempts of improving patient selection in cardiac resynchronization therapy (CRT) are mainly based on echocardiographic timing of myocardial velocity peaks. Regional myocardial function is neglected. Apical transverse motion (ATM) is a new parameter to quantify apical rocking as an integrative surrogate of both temporal and functional inhomogeneities within the left ventricle. In ...

Patients who undergo abdominal surgery experience a phenomenon commonly called postoperative ileus (POI). Standard of care requires patients to get out of bed, sit in a chair, and begin ambulating the first postoperative day. No evidence supports standard care activities reduce POI duration. Rocking-chair motion has shown promise in reducing POI duration. Sixty-six participants were randomized ...

ii) a exible polymer with rigid bonds and iii) a exible polymer with exible bonds. The use of a very e cient pivot algorithm has made it possible to simulate very long chains, with up to several thousand titrating groups. The results have been compared to a mean eld approximation for a rigid rod and variational results emanating from a Flory type approach. It is found that the rigid rod mean el...

The design of retaining walls depends on the magnitude of active pressure exerted from the backfill. Therefore, estimating the scale of this pressure is a fundamental factor in the design. In this study, to assess the active earth pressure, a rigid retaining wall was built capable of translating and/or rotating with adjustable speed. Further, several physical tests were conducte...

Performance and reliability of any rotating machine can be studied by proper dynamic analysis of the machine. In this regard, this paper presents the method to study the dynamic response of the shaft of a Pelton turbine due to the impact of water jet. Equations of motion for the bending vibration of Pelton turbine assembly, in two transverse directions, is developed by using Lagrange equation o...

introduction: motion of the patient during myocardial perfusion spect could potentially results in false perfusion defects. the effect of different reconstruction methods on these artifacts is not studied. clarification of the relation between the extent, severity and duration of motion with the resultant artifacts may be helpful in designing special soft wares for motion correction. this study...
