Hemorrhoids are a common and painful condition,with conventional treatments such as endoscopic rubber band ligation(ERBL)and injection sclerotherapy often falling short due to high recurrence rates and significant post-operative pain.A clinical trial by Qu et al introduces a novel approach called endoscopic polidocanol foam sclerobanding(EFSB).This multicenter randomized trial involved 195 patients with grade II and III internal hemorrhoids and demonstrated that EFSB significantly reduced recurrence rates and post-procedural pain while improving symptom relief and patient satisfaction compared to *** study's strengths include its robust design,comprehensive outcome evaluation,and patient-centered *** limitations such as the single-blind design and relatively short follow-up period,the findings suggest that EFSB could enhance clinical practice by offering a more effective and patient-friendly treatment *** research is needed to validate these results and explore the long-term benefits and cost-effectiveness of EFSB.

Impact of Cattaneo-Christov Heat Flux in the Nanofluid Flow over an Inclined Permeable Surface with Irreversibility Analysis

引用

Journal of Applied mathematics and Physics 2024年第4期12卷 1582-1595页

作者： Muhammad Ramzan Hina gul Department of Computer Science Bahria University Islamabad Pakistan

This study discusses the magnetohydrodynamic nanofluid flow over an inclined permeable surface influenced by mixed convection, and Cattaeo-Christov heat flux. The heat transfer analysis is performed in the presence of a heat source/sink and thermal stratification. To gauge the energy loss during the process, an irreversibility analysis is also performed. A numerical solution to the envisaged problem is obtained using the bvp4c package of maTLAB. Graphs are drawn to assess the consequences of the arising parameters against the associated profiles. The results show that an augmentation in the magnetic field and nanomaterial volume fraction results in an enhancement in the temperature profile. A strong magnetic field can significantly reduce the fluid velocity. The behavior of the Skin friction coefficient against the different estimates of emerging parameters is discussed. .
