The culverts are used to safely convey water under railways, highways, and overpasses. They are utilized in drainage areas or water channels and in areas where the bearing capacity of soil is low. The design and construction of this crucial infrastructure need to be improved to meet contemporary demands of reliability and affordability.

They serve as a load transfer path and take a significant portion of the overall shear. Joints in RC structures constructed with no seismic provisions have an insufficient capacity and ductility under lateral loading and can cause the progressive failure of the entire structure.

- CaTiO is identified as a potential scaffold material for bone implantation, with improved pseudo-piezoelectric properties when doped with magnesium and iron.
- The study employed sol-gel synthesis and spark plasma sintering to create both pure and doped CaTiO, revealing that doping enhances structural strain and defects, leading to a stronger pseudo-piezoelectric effect.
- Magnesium doped CaTiO produced a charge of (2.9 ± 0.1) pC, while iron doping resulted in the highest charge of (3.6 ± 0.2) pC, indicating that doping can be used to optimize piezoelectric responses for better bone tissue engineering applications.
A comparative study between 17 Japanese and 19 Indian patients with oral squamous cell carcinomas (OSCCs) revealed that the tumour prognostic indicator mean vessel density (MVD) count for angiogenesis was relatively high at 57.1 in Indian as compared to 39.3 in Japanese (P=0.
