Experimental study on fire extinguishing with a newly prepared multi-component compressed air foam

The Application of Concurrent Engineering in the Installation of Foam Fire Extinguishing Piping System

Although the concept of concurrent engineering has been widely applied in the manufacturing industry, there is growing awareness and interest in the adoption of Concurrent Engineering (CE) in the Construction Industry because CE has the potential to make construction projects less fragmented, reduce project duration, improve project quality, reduce total project cost and increase project compet...

Fire and Explosion Prevention in Compressed Air Plants

Physical Modeling of Oil Well Fire Extinguishing Using a Turbojet on a Barge

There are reports of gas and oil wells fire due to different accidents. Many different methods are used for fire fighting in gas and oil industry. Traditional fire extinguishing techniques are mostly faced with many problems and are usually time consuming and needs lots of equipments. Besides, they cause damages to facilities, and create health and environmental problems. This article proposes ...

single-step synthesis of multi-component spirobarbiturates using ionic liquids and synthesis of substituted pyridine filled with catalysts supported on solid substrate

in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...

Performance of Multi-Level and Multi-Component Compressed Bitmap Indexes

Bitmap indexes are known as the most effective indexing methods for range queries on append-only data, especially for low cardinality attributes. Recently, bitmap indexes were also shown to be just as effective for high cardinality attributes when certain compression methods are applied. There are many different bitmap indexes in the literature but no definite comparison among them has been mad...
