| 1 | Numerical Analysis of Complicated Heat and Mass Transfer inside a Wustite Pellet during Reducing to Sponge Iron by H_2 and CO Gaseous Mixture显示文摘Heat and mass transfer through a wustite pellet during converting to sponge iron was investigated.Pellet was reduced by agaseous mixture containing CO and H_2.The grain model was considered to simulate gas-solid reaction rate.A finite volume method(FVM)was implemented for solving the governing equations.The heat transfer mechanism around the pellet includes radiation and convection and within the pellet,effective heat transfer is considered as a blend of particles conduction and intraparticle radiation.Heat and mass distribution along the radius of pellet for two cases of reducing gases composed of pure H_2 and pure CO was investigated.Local fractional reduction through the pellet was plotted to examine the heat and mass transfer behavior within the pellet and find their relevance with reduction degree.Afterwards,the impacts of pertinent parameters including gas ratio,pellet size and porosity were studied. | Zare Ghadi ARIYAN Valipour MOHAMMAD SADEGH Biglari MOJTABA | 2016 | Journal of Iron and Steel Research(International)2016，23，11： | 2 |

| 11 | Predictors of readiness for discharge in mothers of preterm infants: The role of stress, self-efficacy and perceived social support显示文摘Objective:To determine the predictive role of stress,self-efficacy,and perceived social support on readiness for discharge in mothers of preterm infants.Methods:The present cross-sectional,descriptive-analytical study was conducted on 120 mothers of preterm infants admitted to hospitals affiliated to Lorestan University of Medical Sciences,Iran in 2019.Participants were selected by a convenience sampling method and based on inclusion criteria.Data collection tools included the demographic questionnaire of mothers and infants,parent perceptions of their child's hospital discharge,parental stressor scale:neonatal intensive care unit,perceived maternal parenting,and multidimensional scale of perceived social support.Data were analyzed using Pearson correlation and stepwise regression at the significance level of 0.05.Results:Infant behavior and appearance,situational belief,and family support achieved the highest mean score from parents'stress,self-efficacy,and perceived social support dimensions,respectively.There was a significant relationship between stress,self-efficacy,and perceived social support with readiness for discharge in mothers of preterm infants(P<0.001).The score of mothers'readiness for discharge decreased by 0.07 per 1-point increase in stress score,and the score of readiness for discharge in mothers of preterm infants rose by 0.35 and 0.43,respectively,for a unit increase in the scores of self-efficacy and perceived social support.Conclusions:Stress,self-efficacy,and perceived social support can be considered as predictors of readiness for discharge in mothers of preterm infants.It is suggested that nurses in neonatal intensive care units provide a better platform for the readiness for discharge in mothers of preterm infants by reducing stressors and increasing maternal self-efficacy and social support. | Sedighe Valipour Fatemeh Estebsari Maliheh Nasiri Parvaneh Vasli | 2022 | Asian pacific Journal of Reproduction2022，11，6： | 1 |
