(and the associatedcritical flowrates), foam is generated efficiently with bubble sizes being of the order of the pore sizes, i.e. micrometric. Bubble sizes and gas fraction can be tuned by tuning the overall and the relative flow rates, with the bubble size being roughly inversely ...
In recent years, green façades (also called vertical greenery systems) have become increasingly important. Although cities occupy only 2% of the global land area, more than half of the world’s population lives in cities and urban agglomerations. Three-quarters of Europe’s population live in ...
These contain only pressurised carbon dioxide gas and therefore leave no residue. Carbon Dioxide (CO2) extinguishers are used on fires involving burning liquids (Class B), and electrical fires, such as of large computer equipment, so are practical in offices. CO2 works by suffocating the fire an...

construction phase of these projects. The current standard emergency air horns located throughout these wood frame construction sites would be deemed useless as hearing protection and electric/gas powered tools make it difficult if not nearly impossible to hear the alert in the event of a fire ...

A system for sensing smoke and fire, primarily through the sensing of associated carbon monoixide and optionally with supplementary heat sensing, and for sensing hazardous gases and vapors. The system
The threat to people’s lives and property posed by fires has become increasingly serious. To address the problem of a high false alarm rate in traditional fire detection, an innovative detection meth...
and a large amount of volatile compounds [20,21,22,23]. Afterward, a violent burning reaction would happen to form a fire hazard. To make more efficient fire management, fire sensors have become a desirable strategy. One traditional fire alarm is gas sensors to detect the gas mixture by ...
