Canadian Anaesthetists’ Society Journal, 1963 The inflammability of intestinal gases was demonstrated by Vulparious in the seventeenth century. The main gases incriminated are methane and hydrogen and their production is increased by a leguminous diet or by excessive fermentation in cases of pyloric stenosis with gross gastric stasis.

Frequency Locking for Combustion Synthesis in Periodic Medium [PDF]
, 2003 Solutions of a 1-D free-interface problem modeling solid combustion front propagating in combustible mixture with periodically varying concentration of reactant exhibit classical phenomenon of mode locking. Numerical simulation shows a variety of locked periodic, quasi-periodic and chaotic solutions.

Advanced Functional Materials, EarlyView.A highly‐entangled polyacrylamide (HE‐PAM) hydrogel is designed as an aqueous electrolyte for the fast charging/discharging properties in Zn/MnO2 batteries. Such hydrogel electrolyte possessed excellent mechanical characters, stable cycling capability, and superb rate performance under high current densities. These characters can also be applied in the

An improved grey wolf algorithm and its localization research in complex indoor environments
Scientific ReportsIn complex indoor environments, traditional localization methods often suffer from non-line-of-sight (NLOS) and multipath problems, which lead to unsolvable or incorrectly solved mathematical localization models, thereby limiting localization accuracy. A
