Objectives: Based on the conceptual overlap between shift-&-persist (S&P) and culturally based strategies (critical civic engagement [CCE] and spiritually based coping), this study tests whether associations between these three previously disparate strategies are attributable to the existence of a higher-order coping construct: culturally informed S&P.

Methods: Among 364 diverse minoritized youth (M = 18.79, 85.

Water is often considered as the highest performance working fluid for liquid-vapor phase change due to its high thermal conductivity and large enthalpy of vaporization. However, a wide range of industrial systems require using low surface tension liquids where heat transfer enhancement has proved challenging for boiling and evaporation. Here, we enable a new paradigm of phase change heat transfer, which favors high volatility, low surface tension liquids rather than water.

High power density electronics are severely limited by current thermal management solutions which are unable to dissipate the necessary heat flux while maintaining safe junction temperatures for reliable operation. We designed, fabricated, and experimentally characterized a microfluidic device for ultra-high heat flux dissipation using evaporation from a nanoporous silicon membrane. With ~100 nm diameter pores, the membrane can generate high capillary pressure even with low surface tension fluids such as pentane and R245fa.

Background: Chronic obstructive pulmonary disease (COPD) is associated with clinically relevant extra pulmonary manifestations; one of them is weight loss. However, there are very few studies from North India available in relation to body mass index (BMI) and Oxygen saturation (SpO2) with COPD.

Aims: To study the prevalence of undernutrition among stable COPD patients and correlation of COPD severity with SpO2 and BMI.

Biosorption of Pb(II) on bael leaves (Aegle marmelos) was investigated for the removal of Pb(II) from aqueous solution using different doses of adsorbent, initial pH, and contact time. The maximum Pb loading capacity of the bael leaves was 104 mg g(-1) at 50 mg L(-1) initial Pb(II) concentration at pH 5.1.
