Thermal Monitoring and Analysis of Moxa Cone Smoldering in Umbilical Therapy

This study establishes and validates a multiphysics thermal model for navel moxibustion by combining contact thermocouple measurements and infrared thermography, revealing that the moxa cone's peak temperature reaches approximately 650°C while the dough partition effectively maintains the tissue interface within a safe 43.0–46.5°C range.

Divergent ECM Performance Profiles in LEED-Certified IT Park Buildings: A Comparative eQUEST Simulation Study of Two Core and Shell Buildings in Bangalore’s Temperate Climate

This study utilizes eQUEST simulations to reveal that despite achieving comparable overall LEED v4 energy savings, two Core and Shell IT park buildings in Bangalore's temperate climate exhibit divergent end-use performance profiles, most notably a counterintuitive increase in chilled-water pump energy consumption in one building, thereby demonstrating that HVAC plant configuration critically shapes energy saving distributions more than climate or certification frameworks alone.
