Background. Controlling and manipulating inter-repetition rest (IRR) could develop diverse levels of fatigue and manifest changes to lifting mechanics. Objectives. This studychr('39')s objective was to examine the effect of IRR on the kinematic of snatch lifting during multiple set exercise protocol. Methods. Fifteen male (n=15) athletes participated in this study (age = 21.0 ± 1.41 years; bo...
Background: Ultrasound propagation velocity was measured experimentally in normal, fibroadenoma and ductal carcinoma breast tissues, in order to distinguish normal breast tissue from tumors. Materials and methods: In quantitative measurements of ultrasound velocity, 403 breast tissue images were selected, comprising 130 normal breast tissue, 130 fibroadenoma, and 143 ductal carcinoma tumors. Th...
Background & Aim: Preeclampsia is the major cause of maternal and perinatal morbidity and mortality. Transcranial Doppler(TCD) as a noninvasive procedure is used to assess hemodynamic changes in middle cerebral artery(MCA). Knowing the influence of normal pregnancy and preeclampsia on brain hemodynamics is essential for proper management of anesthesia, labor and vasoactive drug usage in the...
In this study, we obtained two-dimensional tomography maps of the Rayleigh wave group velocity for the northwest part of the Iranian Plateau in order to investigate the structure of the crust and the uppermost mantle of NW Iran. To do this, the local earthquake data during the period 2006-2013, recorded by the 10 broadband stations of the Iranian seismic network (INSN) were used. After the prel...
