nowadays acoustic emission (ae) testing based on the kaiser effect (ke) is increasingly used to estimate the in-situ stress in laboratories. in this work, this effect is assessed on cylindrical specimens in numerical simulations of the cyclic loadings including loading, unloading, and re-loading cycles using a 3d code called the particle flow code (pfc) based upon the distinct element method. t...

Masalah mengukur tekanan biji-bijian dalam belubur telah dianalisa. Kesulitan yang timbul di masamasa yang lepas dikaji sepenuh-penuhnya dan satu percubaan telah dibuat untuk mengurangkan kesulitan ini. Langkah-langkah penting dalam peralatan semasa memasang, dan kesan ke atas keputusan-keputusan telah dinyatakan. Pemeriksaan juga telah dilakukan ke atas belubur model yang telah dipasang dengan...

Recent evidence suggests that exercising the antagonist musculature acutely enhances subsequent performance for the agonist musculature. The purpose of this study was to examine the effects of different rest intervals between sets for exercises that involve antagonistic muscle groups, a technique referred to as antagonist paired sets (APS). Fifteen recreationally trained men were tested for kne...

To determine the effect of age on quadriceps muscle blood flow (QMBF), leg vascular resistance (LVR), and maximum oxygen uptake (QVO2 max), a thermal dilution technique was used in conjunction with arterial and venous femoral blood sampling in six sedentary young (19.8 +/- 1.3 yr) and six sedentary old (66.5 +/- 2.1 yr) males during incremental knee extensor exercise (KE). Young and old attaine...

We investigate the origin of the kink effect (KE) in the relativistic mean field theory by transforming the single-particle Dirac equation into a Schrödinger-like equation. It is found that relativistic self-consistent effects as well as contributions coming from the ρ meson determine the actual structure of the KE. However, the spin-orbit force generated by the ρ meson has no significant influ...

PURPOSE To measure the effects of using time-resolved (TR) versus time-averaged (TA) ventricular segmentation on four-dimensional flow-sensitive (4D flow) magnetic resonance imaging (MRI) kinetic energy (KE) calculations. MATERIALS AND METHODS Right (RV) and left (LV) ventricular KE was calculated from 4D flow MRI data acquired at 3.0T in 10 healthy volunteers and five subjects with cardiac d...

This paper presents numerical evidence that for quantum systems with chaotic classical dynamics, the number of scattering resonances near an energy E scales like h D(KE)+1 2 as h ! 0. Here, KE denotes the subset of the classical energy surface fH = Eg which stays bounded for all time under the flow generated by the Hamiltonian H and D (KE) denotes its fractal dimension. Since the number of boun...

UNLABELLED The criterion variables were total weight lifted (Wttot ) determined separately for women and men during BC and KE, and blood lactic acid concentration ([Hla]) determined for a combined female ( N = 10) and male ( N = 10) subset during BC. Subjects performed three separate sets of 4, 8, and 12 repetitions for BC and KE at 65% one-repetition maximum. Rating of perceived exertion for t...
