Analytical investigation of the one dimensional heat transfer in logarithmic various surfaces

AbstractThe purpose of the present study was to investigate of the effect of temperature variation on the logarithmic surface. By using the appropriate similarity transformation for the generation components and temperature, the basic equations governing flow and heat transfer are reduced to a set of ordinary differential equations. These equations have been solved approximately subject to the relevant boundary conditions with numerical and analytical techniques. The reliability and performance of the present method have been compared with the numerical method (Runge–Kutta fourth-rate) to solve this problem. Then, LSM is used to solve nonlinear equation in heat transfer. This method is useful and practical for solving the nonlinear equation in heat transfer. It is observed that the obtained results by present analytical method are very close to result of the numerical method. Furthermore, the results show that the temperature profiles decreased by increasing the α number, and, temperature profiles increased by increasing the β number

Examining memory performance in body dysmorphic disorder (BDD): A comparison study with obsessive compulsive disorder (OCD)

The aim of this study is comparing directly the BDD and OCD disorders in terms of similarities and differences in memory function for the first time. 19 BDD patients, 15 OCD patients and 26 individuals in a healthy control group were recruited from three hospitals in Tehran. They were administered the following subtests of the Wechsler Memory Scale: logical memory (immediate and delayed), verbal paired association (immediate and delayed), digit span and spatial span as well as the Rey�Osterrieth complex figure test (RCFT). The results showed that BDD and OCD groups had lower performance in comparison to the control group across all measures, except for the immediate memory of the verbal paired associate task, which was similar across the three groups. Both the BDD and OCD groups showed poor performance on the auditory-verbal memory tasks. However, only the BDD group showed poor performance in the visual domain (i.e. spatial span and RCFT). This suggest that memory deficits are similar between BDD and OCD patients in the verbal domain. Furthermore, BDD patients demonstrated poorer visual working memory. The findings of this study reveal that BDD and OCD patients have more similarities than differences regarding neuropsychological features, in other words, the idea of the incorporation of BDD within the obsessive-compulsive and related disorders (OCRDs) spectrum in DSM-5 is supported, at least through the viewpoint of neuropsychology. © 2020 Elsevier B.V

The effect of a group discussion about premature newborns between mothers and healthcare team on mother� stress and coping in neonatal intensive care unit

Background: Premature birth is a source of severe stress for parents. The current study aimed to determine the effect of group discussion between mothers and the healthcare team on mothers' stress and coping strategies. Methods: This non-randomized, prospective, interventional study was conducted in 2017. Eighty mothers with premature infants were enrolled in the study (40 mothers in each group). Four sessions of group discussion focusing on family-centered care were conducted for the intervention group. Parental Stress Scale and the Brief COPE were completed for the first three days and two weeks later, and the data were analyzed using t-test and repeated measure ANOVA. Results: Differences in maternal stress reduction between the intervention and control groups were statistically significant (p=0.002). Problem-focused coping strategies were increased significantly in the intervention group (P = 0.01). Conclusions: Group discussions between mothers and healthcare team members as a way to improve the quality of care in the neonatal intensive care unit (NICU) can help mothers stress reduction and improving positive coping strategies. © 2020 Neonatal Nurses Associatio
