Offers a means of increasing the efficiency cycle by reducing par asitic loads such as excess air compressor load and capturing energy that might otherwise be wasted. However, this is not always most effective way overall conver sion. For large gas turbine based plants in particular, best improving to add steam bottoming cycle, creat ing combined power plan. A plant simply what its name suggest...

A thermodynamic process of power generation has been developed for a gas turbine, a steam turbine, and a compressor, supported by adiabatic expansion or compression processes. Recently, the possible inlet temperature of gas turbines has been increased to 1500°C or more, and the inlet temperature of steam turbines also has been increased to 650°C. At these high-temperature conditions, turbine no...

Mechanically-driven syringes used to test peak expiratory flow (PEF) meters must produce the American Thoracic Society (ATS) standard waveforms with PEF accuracy of 2%. However, gas compression within the syringe could result in significant PEF inaccuracy when testing high resistance meters. The gas compression artefact was investigated in a mechanical syringe (PWG; MH Custom Design & Mfg L.C.,...

During forced vital capacity maneuvers in subjects with expiratory flow limitation, lung volume decreases during expiration both by air flowing out of the lung (i.e., exhaled volume) and by compression of gas within the thorax. As a result, a flow-volume loop generated by using exhaled volume is not representative of the actual flow-volume relationship. We present a novel method to take into ac...

serovar isolated from a canal in Louisiana in 1978 revealed it to be identical to that of V. cholerae 01 isolated in 1905 from a pilgrim at the El Tor quarantine station. The two strains are associated with sharply contrasting habitats. Ranges of variation of 5 to 15% in procaryotic 5S rRNA sequences between species are typical; variation within species may be 2% or greater. Because the 5S rRNA...

This empirical analysis examines the use of the live-streaming application Periscope in three crises that occurred in 2015. Qualitative and quantitative analyses of tweets relating to the Amtrak derailment in Philadelphia, Baltimore protests after Freddie Grey’s death, and Hurricane Joaquin flooding in South Carolina reveal that this recently deployed application is being used by both citizens ...
