BACKGROUND Maintaining normothermia during off-pump coronary artery bypass (OPCAB) surgery is difficult. The purpose of the present study is to determine the effect of the Inditherm Patient Warming System (IPWS) with standard institutional care during OPCAB surgery. METHODS A control cohort of 10 patients undergoing OPCAB surgery received standard conventional therapy. A study cohort of anoth...

Almost three quarters of the hydrocarbon (HC) emissions emitted by an automobile in a typical drive-cycle are produced during the first three minutes of its operation called the coldstart period. In this paper, we propose a way to decrease cold start emissions. A Model-Based paradigm is used to aid the generation of an efficient controller. The controller is built around a mean value engine mod...

Resonant metal nanostructures exhibit an optically induced electrostatic potential when illuminated with monochromatic light under off-resonant conditions. This plasmoelectric effect is thermodynamically driven by the increase in entropy that occurs when the plasmonic structure aligns its resonant absorption spectrum with incident illumination by varying charge density. As a result, the elevate...

The engine and its exhaust flow behaviors are investigated in a turbo-charged gasoline direct injection engine under simulated cold-fast-idle condition. The metrics of interest are the exhaust sensible and chemical enthalpy flows, and the exhaust temperature, all of which affect catalyst light off time. The exhaust sensible enthalpy flow is mainly a function of combustion phasing; the exhaust c...

Song, Xiaowei, and Benjamin Rusak. Acute effects of light on body temperature and activity in Syrian hamsters: influence of circadian phase. Am J Physiol Regulatory Integrative Comp Physiol 278: R1369–R1380, 2000.—Light exposure at night causes an acute increase in human body temperature, which normally falls during the night. This change is largely attributable to the suppression by light of t...

Hybrid perovskites form an emerging family of exceptional light harvesting compounds. However, the mechanism underpinning their photovoltaic effect is still far from understood, which is impeded by a lack of clarity on their structures. Here we show that iodide ions in the methylammonium lead iodide migrate via interstitial sites at temperatures above 280 K. This coincides with temperature depe...
