This study aims to understand the patterns of content-sharing behaviour on major social media platforms by young adult users with reference to how these sharing patterns are influenced by two main sociocultural factors in their lives, religiosity and social conformity.

Online surveys including both the ATSCI test for social conformity as well as the Hoge test for religiosity were filled out by 590 participants. In-depth interviews with six participants representative of the same population were conducted to deepen analysis of key variables explored in the surveys. The design of the interviews was semi-structured, whereby the focus was to achieve a general overview of participants' intentions and habits regarding sharing information via social media.

The findings show a significant positive impact of religiosity and social conformity on users' sharing intention which, in turn, affects their inclination towards verifying the content they share.

The authors' findings emphasise how users bear the onus of correcting the online information space. It paves the way for future research by recognising the value of independent corroboration amongst users.

This study lends key support to the growing body of research on social media use in societies in which shared religious and cultural values tend to clearly impact everyday social interaction.

Inclination angle has been reported to have an enhancing effect on the thermal-hydraulic characteristics and entropy of some thermal systems. Therefore, this paper aims to numerically investigate the effects of inclination angle, volume concentration and Reynolds number on the thermal and hydraulic characteristics and entropy generation rates of water-based Al₂O₃ nanofluids through a smooth circular aluminum pipe in a turbulent flow.

A constant heat flux of 2,000 Watts is applied to the circular surface of the tube. Reynolds number is varied between 4,000 and 20,000 for different volume concentrations of alumina nanoparticles of 0.5%, 1.0% and 2.0% for tube inclination angles of ±90o, ±60o, ±45o, ±30o and 0o, respectively. The simulation is performed in an ANSYS Fluent environment using the realizable kinetic energy–epsilon turbulent model.

Results show that +45o tube orientation possesses the largest thermal deviations of 0.006% for 0.5% and 1.0% vol. concentrations for Reynolds numbers 4,000 and 12,000. −45o gives a maximum pressure deviation of −0.06% for the same condition. The heat transfer coefficient and pressure drop give maximum deviations of −0.35% and −0.39%, respectively, for 2.0% vol. concentration for Reynolds number of 20,000 and angle ±90o. A 95%–99.8% and 95%–98% increase in the heat transfer and total entropy generation rates, respectively, is observed for 2.0% volume concentration as tube orientation changes from the horizontal position upward or downward.

Research investigating the effect of inclination angle on thermal-hydraulic performance and entropy generation rates in-tube turbulent flow of nanofluid is very scarce in the literature.
