بررسی تاثیر دو مانور ثبات دهنده شکمی (گود کردن و سفت کردن شکم) با استفاده از pressure biofeedback روی میزان فعالیت بدست آمده از سیگنال الکترومیوگرافی عضلات اکستانسور ناحیه کمری ـ لگنی در حین انجام اکستنشن هیپ در وضعیت دمر در زنان سالم و مبتلا به کمردرد مزمن غیر اختصاصی.
Weak vertical coupled bunch instability with oscillation amplitude at μm level has been observed in SPEAR3. The instability becomes stronger when there is a vacuum pressure rise by partially turning off vacuum pumps and it becomes weaker when the vertical beam emittance is increased by turning off the skew quadrupole magnets. These confirmed that the instability was driven by ions in the vacuum...
Catamaran added V-like center bow (INCAT) is investigated as a wave-piercing vessel to decrease vertical acceleration and diminish slam events during sea-keeping operation. The catamaran and the vessel bow were modeled and the vertical acceleration of model was validated with experimenal test. The geometry of V-like center-bow such as slope of center bow and elevation from demi-hulls was optimi...
Fish must orient in three dimensions as they navigate through space, but it is unknown whether they are assisted by a sense of depth. In principle, depth can be estimated directly from hydrostatic pressure, but although teleost fish are exquisitely sensitive to changes in pressure, they appear unable to measure absolute pressure. Teleosts sense changes in pressure via changes in the volume of t...
