Variational iteration method along with intelligent computing system for the radiated flow of electrically conductive viscous fluid through porous medium.

This article aims to investigate the analytical nature and approximate solution of the radiated flow of electrically conductive viscous fluid into a porous medium with slip effects (RFECVF). In order to build acceptable accurate solutions for RFECVF, this study presented an efficient Levenberg-Marquardt technique of artificial neural networks (LMT-ANNs) approach. One of its fastest back-propagation algorithms for nonlinear lowest latency is the LMT. To turn a quasi-network of PDEs expressing RFECVF into a set of standards, the appropriate adjustments are required. During the flow, the boundary is assumed to be convective. The flow and heat transfer are governed by partial differential equations, and similarity transform is the main tool to convert it into a coupled nonlinear system of ODEs. The usefulness of the constructed LMT-ANNs for such a modelled issue is demonstrated by the best promising algebraic outputs in the E-03 to E-08 range, as well as error histogram and regression analysis measures. Mu is a controller that oversees the entire training procedure. The LMT-ANNs mainly focuses on the higher accuracy of nonlinear systems. Analytical results for the improved boundary layer ODEs are produced using the Variational Iteration Method, a tried-and-true method (VIM). The Lagrange Multiplier is a powerful tool in the suggested method for reducing the amount of computing required. Further, a tabular comparison is provided to demonstrate the usefulness of this study. The final results of the Variational Iteration Method (VIM) in MATLAB have accurately depicted the physical characteristics of a number of parameters, including Eckert, Prandtl, Magnetic, and Thermal radiation parameters.

Barriers to gender equity for female healthcare academicians and researchers in Pakistan: Is it still an issue?

Introduction: Gender inequity in healthcare academia is rising. Female healthcare professionals are struggling to balance their work and family leading to reduced productivity and disparity in three main areas of academic evaluation including teaching, service and research. Objective: The objective of the current study was to explore perceptions of healthcare academicians regarding gender equity and its associated barriers in healthcare academia in Pakistan. Methodology: A qualitative study design was used. Study site for this research included medical colleges, pharmacy schools and healthcare educational institutes. Study respondents included healthcare professionals including doctors and pharmacists working as faculty members. Snow ball sampling was used and interviews were conducted till saturation point was achieved. All interviews recorded were transcribed verbatim. Transcribed interviews were then subject to thematic analysis and were analyzed for relevant content. Results: Thematic analysis of the study yielded many themes and sub themes. The main themes include: Gender equity an issue for healthcare academicians; Barriers toward promoting gender equity among healthcare academicians; Perceived teaching effectiveness among female healthcare academicians; Professional relationship of female healthcare academicians; Representation of female healthcare academicians at leadership positions; Research opportunities for female healthcare academicians; impact of academia as profession on married life and Strategies for improving gender equity disparities in academia of healthcare profession. The results showed that almost all the females as well as male healthcare academicians were of the view that female academicians are competent, hardworking and committed with their jobs. Mixed responses were observed regarding teaching effectiveness of female academicians. Half of the females as well male healthcare academicians thought that female were more effective teachers while other half was of the view that teaching effectiveness is based on individual trait irrespective of gender. Conclusion: The results of the present study concluded that majority of the male as well as female healthcare professionals perceived gender equity as an issue in academia in Pakistan, especially in underprivileged areas. Non-conducive work environment, harassment at workplace and cultural issues were the main barriers identified toward gender equity in healthcare academia in Pakistan.

Isolation of pathogenic Candida species from oral cavity of postpartum females, and its association with obstetric and dental problems.

OBJECTIVE: The aim of the current study was to investigate pathogenic Candida spp. Colonization in oral cavity of postpartum females and its association with adverse pregnancy outcomes (APOs) and dental issues. METHODS: Saliva samples and clinico-demographic data were collected from 267 postpartum females along with 54 non-pregnant females (Jan 2016-March 2018). Isolation of Candida was carried out by using standard microbiological methods and different virulence factors (Esterase activity, phospholipase activity and biofilm formation) were evaluated. RESULTS: Candidacolonization was high in postpartum females (p<0.001, OR = 4.28). This colonization was not significant among females with APOs, however, one to three folds risk was seen with different obstetric and dental factors. High esterase activity was seen among Candida isolates from postpartum females in comparison to control group (p = 0.01). Phospholipase activity of C.albicans isolates from this group was also high (p = 0.001). Majority of the Candida isolates (66.87%) from postpartum females were biofilm formers. Increase in antifungal activity was seen among isolates from postpartum females, with 85% isolates resistant to Fluconazole and Voriconazole (p<0.001) and Amphotericin B resistance was present in 64.38% isolates (p<0.001). CONCLUSION: Postpartum females are more susceptible to oral Candida colonization, which exhibit enhanced virulence characteristics and its carriage are associated with increased risk for development of APOs and dental problems.
