Pistonless rotary engine A pistonless rotary engine is an internal combustion engine that does not use pistons in the way a reciprocating engine does, but instead uses one or more rotors, sometimes called rotary pistons. An example of a pistonless rotary engine is the Wankel engine. The term rotary combustion engine has been suggested[by whom?] as an alternative name for these engines[citation needed] to distinguish them from early (generally up to the early 1920s) aircraft engines and motorcycle engines also known as rotary engines. However, both continue to be called rotary engines and only the context determines which type is meant.

Knovel - Technical Engineering Reference Information Candlestick Patterns Fire by Anna Kraitz | Home and Modern Design Ideas. Porcelain Candlestick Patterns with ingredients to come up with such deep meaning from a Swedish designer Anna Kraitz, Candlestick Patterns Fire really looks good characteristics in terms of form and function, but they all share a related meaning. Candlestick Patterns Fire is a candle light that has attracted the attention of so many who want an innovative him. Have you held a formal dinner or a certain event makes a perfect event.

Internet Time Blog: Communities of Practice Communities of Practice Etienne Wenger and Bill Snyder A hundred of us are tuned in on Saba Live (AKA Placeware), listening to these two champions of communities of practice (CoP). This month's installment of Saba's Human Capital Live!, hosted by Saba CLO Brooke Manville. I found this quite worthwhile. We're talking about professionals. There's "more." Looking at how communities spread and grow, small groups connect with others through people whose role is linking them. This isn't so much a matter of technology, for communities can work with video conferencing, application sharing, listservs, websites, and the standard bag of Internet tricks. CoP is the formal organization recognizing that the informal organization exists. CoP is knowledge up; KM is knowledge down. Johnson & Johnson has maybe a hundred CoP. The "Tech Clubs" at Chrysler evolved into more strategic entities. What are the incentives that make a robust community work? Strategic knowledge management cycle. Metrics?

Roberto (2) - Google Wave As we announced in August 2010, we are not continuing active development of Google Wave as a stand-alone product. Google Wave will be shut down in April 2012. This page details the implication of the turn down process for Google Wave. Stage 1: Google Wave is read-only -- January 31, 2012 In this stage, you will no longer be able to create or edit waves. Robots that try to write to a wave will stop functioning. During this time, you will continue to be able to export your waves using the existing PDF export feature. If you want to continue using Wave, there is an open source project called Walkaround that includes an experimental feature to import all your waves from Google. Quasiturbine Quasiturbine QT-AC Patents for the Quasiturbine (in the most general AC concept with carriages) [1][2][clarification needed] are held by the family of Gilles Saint-Hilaire of Québec. As well as an internal combustion engine, the Quasiturbine has been proposed as a possible pump design, and a possible Stirling engine.[3] It has been demonstrated as a pneumatic engine using stored compressed air, and as a steam engine.[4] There are at least four proposed designs: Two-port with carriages, suitable for use as an internal combustion engine.Four-port without carriages, suitable for use as a pneumatic or hydraulic engine, steam engine or pump.Two-port without carriages, a conceptual design which is hoped to combine some of the advantages of the existing two- and four-port prototypes.Another conceptual design using a fixed charge of gas, with no ports and without carriages, as a Stirling engine. Two-port with carriages[edit] However, ignition with fuel was never achieved. Photo-detonation[edit]

RE<C - A Google.org Project to Develop Electricity from Renewable Energy Sources Our approach to RE<C Through RE<C, we made several investments in companies working on potentially breakthrough technologies. For instance, we invested in companies like Brightsource Energy and eSolar to help expand their work on concentrating solar power technology, and in Potter Drilling to advance its innovative geothermal drilling technology. And we've also sponsored research to develop the most state of the art Geothermal Map of the US, helping better understand the potential for geothermal energy to provide renewable power that’s always available. And we’ve had an engineering team working to improve a type of concentrating solar power technology called the solar power tower. The solar power tower is an exciting technology that works by using a field of mirrors, called heliostats, to concentrate the sun’s rays onto a solar receiver on top of a tower. Over the last few years, we’ve seen a lot of progress in clean energy. What we’ve learned Brayton project overview

Manufacturing Textile factory (Germany, about 1975). Manufacturing is the production of merchandise for use or sale using labour and machines, tools, chemical and biological processing, or formulation. The term may refer to a range of human activity, from handicraft to high tech, but is most commonly applied to industrial production, in which raw materials are transformed into finished goods on a large scale. The manufacturing sector is closely connected with engineering and industrial design. History and development[edit] In its earliest form, manufacturing was usually carried out by a single skilled artisan with assistants. Manufacturing systems: changes in methods of manufacturing[edit] Industrial policy[edit] Economics of manufacturing[edit] On the other hand, most manufacturing may involve significant social and environmental costs. The negative costs of manufacturing can also be addressed legally. Manufacturing and investment[edit] Manufacturing processes[edit] Theories[edit] Control[edit]

Change of flow pattern was observed during pre- and post-fenestrated stent grafting in patient 1. Mentions: Changes of the aortic flow pattern were noted with placement of the fenestrated stent grafts and these changes were consistent with those reported in the literature (23-25).
