Introduction: Duration of labor and pain severity are main factors to fray pregnant women of vaginal delivery and acceptance for elective section. Hence, the purpose of this research was to investigate the effect of massage aromatherapy with lavandula in decreasing the duration of first and second stage of labor in nulliparous women. Methods: The present study is a clinical trial which performe...
The rapid increase of non-linear loads in the last three decades has caused electrical quantities such as voltages and currents in 3-phase distribution systems to become distorted waveforms. This paper reviews, explains and discusses some new concepts, definitions and new available theory in the unbalanced and distorted systems. The usefulness of the proposed practical definitions is investigat...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...

Background: Pain control is considered as the key issue in modern midwifery. Along with medical painkillers, reflexology is viewed as a non-medical and noninvasive method. Hence, we aimed to investigate the effect of reflexology on the intensity of pain and length of labor. Materials and Methods: In this clinical trial, participants included 240 Iranian primiparous women with term and singleton...
Introduction: Labor pain is one of the most severe pains that women experience during the pregnancy period. Inhalation and foot bath are common methods that reduce the pain of labor. The purpose of this study was to compare the effects of warm foot bath with inhalation of rose essence and warm foot bath lonely on pain of labor in primiparous women. Materials and Methods: This randomized clncont...
Introduction: This randomized clinical trial (RCT) was conducted to evaluate whether use of music could reduce the pain and duration of labor. Methods: Between 2010 and 2011, a total of 99 women at 38 weeks or greater with spontaneous labor were randomized to fast music, slow music, and control groups. Labor pain was assessed on a visual analogue scale (VAS) at beginning of the active phase an...
Thyristor rectifiers are widely used in electric railways in order to control the speed. As a consequence of their usage in addition to substantial input lead current, an enormous amount of harmonics is injected into the grid. To avoid such harmonics as well as reactive power compensation, reactive power hybrid filters consisting of active and passive filters are utilized. Regarding different p...
Current network nodes enable connectivity between end-systems by supporting a static and well-defined set of protocols. The forwarding service provided by these network nodes is fixed, simple, and increasingly being implemented in hardware. Active network nodes, on the other hand, enable the unattended, dynamic instantiation of custom programs into the network node, allowing for the introductio...
