Exploration of the effects of Coriolis force and thermal radiation on water-based hybrid nanofluid flow over an exponentially stretching plate.

Hybrid nanofluids' enhanced thermophysical properties make them applicable in a plethora of mechanical and engineering applications requiring augmented heat transfer. The present study focuses on a three-dimensional Copper-Aluminium Oxide [Formula: see text]-water based hybrid nanofluid flow within the boundary layer with heat transfer over a rotating exponentially stretching plate, subjected to an inclined magnetic field. The sheet rotates at an angular velocity [Formula: see text] and the angle of inclination of the magnetic field is [Formula: see text]. Employing a set of appropriate similarity transformation reduces the governing PDEs to ODEs. The resulting ODEs are solved with the finite difference code with Shooting Technique. Primary velocity increases at large rotation but the secondary velocity reduces as the rotation increases. In addition, the magnetic field is found to oppose the flow and thereby causing a reduction in both the primary and secondary velocities. Increasing the volume fraction reduces the skin friction coefficient and enhances the heat transfer rate.

Toward an efficient approximate analytical solution for 4-compartment COVID-19 fractional mathematical model.

With the recent trend in the spread of coronavirus disease 2019 (Covid-19), there is a need for an accurate approximate analytical solution from which several intrinsic features of COVID-19 dynamics can be extracted. This study proposes a time-fractional model for the SEIR COVID-19 mathematical model to predict the trend of COVID-19 epidemic in China. The efficient approximate analytical solution of multistage optimal homotopy asymptotic method (MOHAM) is used to solve the model for a closed-form series solution and mathematical representation of COVID-19 model which is indeed a field where MOHAM has not been applied. The equilibrium points and basic reproduction number ( R 0 ) are obtained and the local stability analysis is carried out on the model. The behaviour of the pandemic is studied based on the data obtained from the World Health Organization. We show on tables and graphs the performance, behaviour, and mathematical representation of the various fractional-order of the model. The study aimed to expand the application areas of fractional-order analysis. The results indicate that the infected class decreases gradually until 14 October 2021, and it will still decrease slightly if people are being vaccinated. Lastly, we carried out the implementation using Maple software 2021a.

Do school students with specific learning disabilities have lower emotional intelligence abilities? A cross-sectional questionnaire-based study in Mumbai, Maharashtra, India.

BACKGROUND AND OBJECTIVES: School students with specific learning disabilities (SpLDs) endure academic difficulties, anxiety, and social maladaptation. The primary objective of the present study was to evaluate the emotional intelligence (EI) abilities of these afflicted students. Its secondary objective was to analyze the impact of socio-demographic variables on their EI abilities. SETTINGS AND DESIGN: Cross-sectional single-arm questionnaire-based study was conducted in the Learning Disability clinic in a public medical college in Mumbai. SUBJECTS AND METHODS: SpLD students studying in class standards VII-IX were recruited by non-probability sampling. Their EI (overall, subscales, and settings) scores were measured using the Four EsScale of Emotional Intelligence-Adolescents (FESEI-A) questionnaire; and compared with Indian norm scores by utilizing the Mann - Whitney U test. To evaluate the unadjusted impact that each of the "variables" had on the FESEI-A scores, linear regression or the Mann-Whitney U test, or the Kruskal-Wallis test, was utilized as applicable. RESULTS: SpLD students had similar "overall" EI abilities as their regular peers. Their EI scores in school setting were significantly lower (P = 0.001), but significantly higher in social setting (P = 0.005). At univariate level, presence of co-occurring attention-deficit/hyperactivity disorder was significantly associated with a lower "school setting" score (P = 0.040). Higher socioeconomic status was significantly associated with a higher "overall" score and "family setting" score (P = 0.023 and P= 0.041, respectively). CONCLUSIONS: There is an urgent need to evaluate the EI abilities of SpLD students to identify deficits so that optimum rehabilitation can be facilitated.
