Two-dimensional phase field simulations were performed of grain growth in highly textured materials with equal fractions of 2 texture components, denoted as α and β grains, and assuming 2 values of the grain boundary energies, namely σlow for the boundaries between grains of a different texture component and σhigh for boundaries between grains of a similar orientation, resulting in microstructu...
Solid oxide fuel cells are a potential electrical power source that is silent, efficient, modular, and capable of operating on a wide variety of fuels. Unfortunately, current technologies are severely limited in that they provide sufficient power output only at very high temperatures (>800°C). One reason for this is because the electrodes have very poor (and poorly understood) kinetics. The wor...
Background & Aims: Delivery is a painful event, and the management of labor pain is of utmost importance. The present study aimed to assess the effects of the oral consumption of date palm (Phoenix dactylifera) syrup on labor pain and length of the active phase of labor in nulliparous women. Materials & Methods: This randomized clinical trial was conducted on 64 healthy volunteer nulliparous w...
Because of its sparsity, triple-base number system is used to accelerate the scalar multiplication in elliptic curve cryptography. Yu et al. presented an estimate for the length of triple-base number system at Africacrypt 2013. However, the efficiency of scalar multiplication is not only associated with the length of representation but also the numbers and costs of doubling, tripling, quintupli...
Introduction: Breathing techniques as Lamaze methods are utilized with the aim to control the labor pain. Breathing techniques help women to well adopt with labor pain. The studies reveal that adoption with labor pain can prevent the prolonged labors. The aim of the present study is to investigate the effects of breathing techniques on the length of labor active phase and its second stage. ...
In this work, the triple convolution of Daubechies wavelet is used to solve the three dimensional (3D) microscale Dual Phase Lag (DPL) problem. Also, numerical solution of 3D time-dependent initial-boundary value problems of a microscopic heat equation is presented. To generate a 3D wavelet we used the triple convolution of a one dimensional wavelet. Using convolution we get a scaling function ...
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...
As a first step towards mechanistic studies of fuel cell electrodes with both well-defined and functionally representative structural features, two-dimensional anti-dot metal films with tunable features are prepared. The fabrication employs a facile, sacrificial templating method, known as polymer sphere lithography, and the resulting metal films are fully connected, yet fully porous. Using ini...
