Rotating machinery or turbomachinery is a machine with a rotating component that transfers energy to a fluid or vice versa. Rotating machines are one of the most widely used machines. They are used in everyday life, at least once a day. We find a turbomachine (fan) in a hair dryer and in a computer. We find a turbomachine (pump) in a refrigerator. Other commonly used household machines are clothes washers and dish washers. These machines need to drain the dirty water and replace with clean water. To do so an important component of these machines is a pump that is used to remove the dirty water. A water pump (hydrodynamic pump) is also essential to our car?s operation by maintaining an optimum operating temperature of the engine. The pump ensures that the coolant keeps circulating through the engine block, hoses and radiator, and maintains an optimum operating temperature. Turbomachines are also key machines used in power generation, fluid transportation, the processing industry and energy conversion. This book presents recent developments in improving the aero-thermal performance and the efficiencies of rotating machines.
Historical Perspectives on East Asian Science, Technology, and Medicine brings together over fifty papers by leading contemporary historians from more than a dozen nations. It is the third in a series of books growing out of the tri-annual International Conference on the History of Science in East Asia, the largest and most prestigious gathering of scholars in the field. The current volume broadens the field's traditional focus on China to include path-breaking work on Vietnam, Korea, Japan, the Philippines, and even the transmission of Asian science and technology to Europe and the United States. Topics covered include: traditional Chinese, Vietnamese, and Filipino medicines; Chinese astronomy; Japanese earthquakes; science and technology policy; architecture; the digital revolution; and much else.
This book studies identity formation and transformation in twentieth-century China by focusing on women's autobiographical writing.
The main theme of this book is the interaction between two “places,” China and Guanzhong, the capital area of several dynasties. It addresses such questions as What do we mean by “local”? Did the inhabitants of a locality believe that being “local” required them to assume a certain identity? If so, how did they talk and write about it? Were there spatial and temporal differences in the representation of locales? This work examines how Guanzhong literati conceptualized three sets of relations: central/regional, “official”/“unofficial,” and national/local. It further traces the formation over the last millennium of the imperial state of a critical communal self-consciousness, the role of this consciousness in constructing a local identity and promoting an “unofficial” space for nonofficial elite activism, and the effect of the presence (or absence) of this consciousness on literati views of central-regional relationships. The issue here is not whether there can be a shared national culture, but whether this culture can be perceived as having regional variations and therefore contributing to the formation of a local identity.

Seek to learn what you do not know… Hubert ‘Bertie’ Thwaites is struggling with the Chinese bureaucracy and their refusal to approve his employer’s plan to establish a rail line from Shanghai to Beijing.
