At long range, the low order acoustic modes constitute some of the most energetic arrivals. Prior to using these signals in tomographic or matched field inversions, it is important to understand their fluctuation statistics. Long vertical line arrays installed as a part of the Acoustic Thermometry of Ocean Climate (ATOC) experiment provided a unique opportunity to measure low-order acoustic mod...
The purpose of this quisi experimental research was to study the effect of transcoutaneous electrical nerve stimulates (TENS) with different frequencies in postoperative pain in 90 patient undergoing abdominal surgery. 30 patients received TENS with 5 HZ (group A), 30 patients received TENS with 80 HZ (group B) and 30 patients received TENS with 20 HZ (group C). Pain relisf in group B (high f...
Human cytomegalovirus(HCMV) infection has been shown to contribute to vascular disease through the induction of angiogenesis. However, the role of microRNA in angiogenesis induced by HCMV infection remains unclear. The present study was thus designed to explore the potential effect of miR-1217 on angiogenesis and to disclose the underlying mechanism in endothelial cells. We found that HCMV infe...
Objective: One of the parameters showing the correct phonetic and phonological development is the correct and clear articulation of vowels is achieved by changing the shape of vocal cords through altering the height and position of the tongue and the movement of the lips and jaw. The tongue’s height and position are the basis of the production and difference of vowels. In other words, the raw s...
