Metered-dose inhaler (MDI); the mouthpiece slots into the back of the spacer.. To use an inhaler without a spacer requires coordinating several actions in a set order (pressing down on the inhaler, breathing in deeply as soon as the medication is released, holding your breath, exhaling), and not everyone is able to master this sequence.
With the outbreak of the Second World War, and the decline in numbers of the puffers during the 1930s, led the Admiralty to order the Victualling Inshore Craft, to a design based on two recent puffers, the Hay boats Anzac and Lascar. These were both coal-fired and steam-powered, limiting the pressure on supplies of fuel oil and diesel, though ...

General parameters used for constructing nose cone profiles. Given the problem of the aerodynamic design of the nose cone section of any vehicle or body meant to travel through a compressible fluid medium (such as a rocket or aircraft, missile, shell or bullet), an important problem is the determination of the nose cone geometrical shape for optimum performance.
The puffers developed from the gabbart, small single masted sailing barges, which took most of the coasting trade.The original puffer was the Thomas, an iron canal boat of 1856, less than 66 ft (20 m) long to fit in the Forth and Clyde Canal locks, powered by a simple steam engine without a condenser, since as it drew fresh water from the canal there was no need to economise on water use.
