. Neonatal hypothermia is a worldwide health burden with an incidence ranging from 32% to 85% in hospitals and 11% to 92% in homebirths. It is prevalent in Nepal and associated with increased morbidity and mortality. The study objective was to identify key practice standards of newborn thermal management in Nepal. . Our subjects included 6 lead newborn physicians from major birthing centers in Kathmandu. A modified Delphi process was used to identify the top 5 key practice standards for newborn thermoregulation in the hospital, health post, and home, compiled from 14 World Health Organization recommended practices. . There was consensus in all ranked practices except using radiant heat sources in the hospital and performing Kangaroo Mother Care in the homebirths. Comments conveyed that interventions during the immediate delivery phase were most impactful and feasible. . Nepali physicians prioritized thermoregulatory practices during the immediate resuscitation period over the post-resuscitation period.

High heat fluxes in electronic devices must be effectively dissipated to prevent local hotspots, which are critical for long-term device reliability. In particular, advanced semiconductor packaging trends toward thin form factor products increase the need for understanding and improving in-plane conduction heat spreading in anisotropic materials. The 2D laser-based Ångstrom method, an extension of traditional Ångstrom and lock-in thermography techniques, measures in-plane thermal properties of anisotropic sheet-like materials.

Efficient thermal management is crucial for optimizing the performance and longevity of automotive engines, particularly as environmental regulations become more stringent and consumer demand for fuel efficiency increases. This paper investigates the energy and exergy performance of a wavy fin-and-tube radiator employing novel ternary nanofluids (TNFs) for enhanced automotive cooling. A theoretical comparative analysis was performed on four distinct ethylene glycol-water solution-based TNF configurations.

Lattice metamaterials emerge as advanced architected materials with superior physical properties and significant potential for lightweight applications. Recent developments in additive manufacturing (AM) techniques facilitate the manufacturing of lattice metamaterials with intricate microarchitectures and promote their applications in multi-physical scenarios. Previous reviews on lattice metamaterials have largely focused on a specific/single physical field, with limited discussion on their multi-physical properties, interaction mechanisms, and multifunctional applications.

Investigating the fascinating world of natural fibers, where Syagrus romanzoffiana fibers (SrFs) are promising substitutes for glass and synthetic fibers in composite materials, is more than interesting. The improvement of SrFs through an environmentally friendly treatment employing sodium bicarbonate (NaHCO₃) at different concentrations (5 %, 10 %, 20 %, and 30 % by weight) over various durations (24, 72, and 168 h) is the subject of this study. The objective is to provide a sustainable and economical approach to enhancing fiber characteristics.

Animals can respond differently to shifting thermal variability versus thermal averages, both of which are changing due to climate warming. How these thermal variables affect parental care behaviors can reveal the ability of parents to modify their behaviors to meet the competing demands of their offspring's thermal needs and self-maintenance, which becomes critical in suboptimal thermal conditions. Further, the time frame used to examine the interplay between temperature and behavioral shifts (e.
