We introduce a new family of iterative methods for solving mathematical models whose governing equations are nonlinear in nature. The new family gives several iterative schemes as special cases. We also give the convergence analysis of our proposed methods. In order to demonstrate the improved performance of newly developed methods, we consider some nonlinear equations along with two complex mathematical models. The graphical analysis for these models is also presented.
In recent years, fluid-structure interaction (FSI) analysis has generated remarkable interest of researchers in interdisciplinary sciences problems, for instance, mechanical engineering, biomedical engineering, i.e., incorporating elastic wall behaviour in human arteries. Here, in this paper, we considered incompressible Newtonian blood flow and the elastic bifurcated artery wall in a non-uniform magnetic field. The considered model of Biomagnetic Fluid Dynamics (BFD) describes both magnetization and electrical conductivity of blood. Moreover, an Arbitrary Lagrangian-Eulerian (ALE) formulation is used by two-way fluid-structure interaction coupling of the problem. Finally, for discretization, a stable

finite element pair is employed to approximate the displacement, velocity and pressure spaces independently and the resulting nonlinear algebraic system is linearized by implementing the Newtons procedure. A quantitative analysis is made against Reynolds number Re and Hartmann number Ha on the bifurcated artery amidst elastic walls showing noticeable effects on recirculation. Also, the displacement field is plotted against Ha for different values of Re and their converse behaviour is observed. The decreasing behaviour for the wall shear stresses of the bifurcated artery are also drawn in context of Ha and Re. Finally, the conclusion is drawn at the end showing the significance of the elastic behaviour of artery walls.
The aim of this paper is to assess proficiency of radiologists and radiology residents in
managing adult life support in cardiopulmonary arrest and acute anaphylactic reaction.
Objective:Pakistan ranks among the countries with highest neonatal mortality rate. Birth related event (Asphyxia neonatorum) is one of the three most common causes of neonatal mortality worldwide. Effective resuscitation during the Golden Minute can improve the mortality and morbidity. In Pakistan, a training programme NeoLiS (Neonatal Life Support) was developed in 2008 which was based on guidelines of ILCOR. The objective of this study was to assess the improvement in knowledge of healthcare professionals attending Neonatal Life Support training workshop.
Methods:It was a retrospective cross sectional study that was conducted in the Neonatology Department of the Children’s Hospital, Lahore. A total of 52 workshops were conducted in 2017-18 in which 1350 health professionals were participated including doctors, nurses and paramedics. Data of all the training workshops were analysed in the study. Knowledge was tested through true/false questionnaires. The results of pre-course test were compared with respective post-course test by entering the data in SPSS and significance in improvement of knowledge was calculated by applying paired t-test. p-value <0.05 was considered significant.
Results: Mean of pre-course and post-course results of all the participants were calculated and post-course results showed significant improvement in knowledge as compared to pre-course tests. Similarly, paired t-test was performed for all the results of doctors,nurses and paramedics on individual basis. The p-value in all groups was < 0.01 which was statistically significant.
Conclusion: Neonatal Life Support (NeoLiS) training course resulted in significant gain in knowledge about neonatal resuscitation by healthcare professionals when assessed

Objective: To assess the hearing loss among the subjects using excessive mobile phone. Methodology: 50 subjects were entered for this study with age ranging from 20 to 40 years using mobile phone for more than 5 years. 25 subjects who used mobile phone for less than (<) 60 min /day formed one group, while 25 subjects who used cell phone for more than (>) 60 min /day formed the second group. The hearing levels of all the subjects were tested using Pure Tone Audiometry (PTA). Duration of mobile phone usage was assessed by questionnaires. Results: There was a significant increase (p-value .00006) in the hearing thresholds at all frequencies in air conduction and bone conduction in right ear in test group compared with the control group. Similar result was found in the left ear except for bone conduction at frequency 4 and 6 (kilo hertz) kHz. Excessive use of mobile phone caused Sensory neural hearing loss and the prevalence was 84% in group who used mobile phone for > 60 min / day and 20% in group who used for < 60 min / day. Conclusion: Excessive use of mobile phone may cause increase in pure tone threshold associated with the duration of usage. The use for more than 5 years with more than 60 minutes daily can produce harmful effects on human hearing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
