Turbulent magnetohydrodynamic natural convection in a heat pipe-assisted cavity using disk-shaped magnesium ferrite nanoparticles

The prospect of altering the thermophysical properties of ferrofluid with an influence of magnetic field leads to improving natural convection in various heat transfer systems. This investigation principally focuses on the studies of electromagnetism-based turbulent natural convection heat transfer of low-density disk-shaped magnesium ferrite/water-based ferrofluid, filled in a novel heat pipe-assisted cubical cavity at various volume fractions. Two flat plate heat pipes were used to maintain temperature differences in the cavity. To advance the buoyancy of the working fluid inside the cavity, deliberately low-density ferrofluid containing disk-shaped particles was formulated using the hydrothermal method. The temperature difference between the two heat pipe-assisted vertical walls was sustained with four distinct temperature ranges from 10 to 25 °C. The ferrofluid filled in the cavity was then subjected to magnetic field ranging from 0 to 350 G to understand the thermomagnetic convection effects on heat transfer. The optimal volume fraction of ferrofluid for maximum heat transfer was found to be 0.05% at a wall temperature difference of 25 °C, owing to 23.51% improvement in average heat transfer coefficient along with 33.37% improvement in average Nusselt number when compared to water. With the application of a magnetic field of 350 G, the average heat transfer coefficient was further enhanced by 10.11%, and the average Nusselt number improved by 6.28% for 0.05% volume fraction in comparison to the condition where no magnetic field was applied.https://link.springer.com/journal/13204hj2023Mechanical and Aeronautical Engineerin

Comparative Evaluation of L-PRF and Ofloxacin Incorporated L-PRF as an Adjunctive to SRP-A Split-Mouth Randomized Clinical Trial

Aim and ObjectivesTo compare and evaluate the clinical efficacy of “ofloxacin incorporated L-PRF” and “L-PRF alone” when used as an adjuvant to non-surgical periodontal therapy. Materials and MethodsA split-mouth study was conducted in 50 patients diagnosed as chronic periodontitis with pocket depth ≥6 with at least one site in each quadrant. All patients underwent scaling and root planning. Test site received with ofloxacin incorporated L-PRF and control site received L-PRF alone. Clinical parameters pocket depth (PD), plaque index (PI), and gingival bleeding index (GBI) were recorded at baseline and 1 month after scaling and root planning. ResultsIn total, 100 sites were treated (50 test group and 50 control group) with no uneventful healing effects. Statistically significant decreases in PD (P = .0001 for both test and control groups), PI (P = .001), GBI (P = .001 for both groups), between pre-treatment and 1 month post-treatment were noted in both test and control groups. For intergroup comparisons, there was a statistically significant difference in all clinical indices (P > .005). ConclusionUse of L-PRF with ofloxacin as an adjuvant to non-surgical periodontal therapy showed better improvements in clinical parameters
