Everett, Massachusetts
Everett is a city in Middlesex County, Massachusetts, United States, directly north of Boston, bordering the neighborhood of Charlestown. The population was 49,075 at the time of the 2020 United States Census. Everett was the last city in the United States to have a bicameral legislature, which was composed of a seven-member Board of Aldermen and an eighteen-member Common Council. On November 8, 2011, the voters approved a new City Charter that changed the City Council to a unicameral body with eleven members – six ward councilors and five councilors-at-large. The new City Council was elected during the 2013 City Election. History and Transportation Everett was originally part of Charlestown, and later Malden. It separated from Malden in 1870. In 1892, Everett changed from a town to a city. On December 13, 1892, Alonzo H. Evans defeated George E. Smith to become Everett's first Mayor. Landfill has expanded the Everett shoreline over the centuries. At some point between 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Electric CF6
The General Electric CF6, US military designations F103 and F138, is a family of high-bypass turbofan engines produced by GE Aviation. Based on the TF39, the first high-power high-bypass jet engine, the CF6 powers a wide variety of civilian airliners. The basic engine core also powers the LM2500 and LM6000 marine and power generation turboshafts. It is gradually being replaced by the newer GEnx family. Development After developing the TF39 for the C-5 Galaxy in the late 1960s, GE offered a more powerful variant for civilian use, the CF6, and quickly found interest in two designs being offered for a recent Eastern Airlines contract, the Lockheed L-1011 and the McDonnell Douglas DC-10. Lockheed eventually selected the Rolls-Royce RB211, but the latter stuck with the CF6 and entered service in 1971. It was also selected for versions of the Boeing 747. Since then, the CF6 has powered versions of the Airbus A300, A310 and A330, Boeing 767, and McDonnell Douglas MD-11. The high b ...

General Electric T700
The General Electric T700 and CT7 are a family of turboshaft and turboprop engines in the class. Design and development In 1967, General Electric began work on a new turboshaft engine demonstrator designated the "GE12" in response to US Army interest in a next-generation utility helicopter. The GE12 was designed and conceived by GE's Art Adamson and Art Adinolfi. In 1967, both GE and Pratt & Whitney were awarded contracts to work parallel with each other to design, fabricate, and test the technology. The Army effort led, in the 1970s, to development of the Sikorsky S-70 Black Hawk, powered by twin GE "T700" turboshafts, the production descendant of the GE12. The T700 was initially bench-tested in 1973, passed military qualification in 1976, and went into production in 1978. The initial "T700-GE-700" is an ungeared free-turbine turboshaft, with a five-stage axial / one-stage centrifugal mixed-flow compressor, featuring one-piece "blisk" axial stages, with the inlet guide vanes a ...

General Electric F404
The General Electric F404 and F412 are a family of afterburning turbofan engines in the class (static thrust). The series is produced by GE Aviation. Partners include Volvo Aero, which builds the RM12 variant. The F404 was developed into the larger F414 turbofan, as well as the experimental GE36 civil propfan. Design and development F404 GE developed the F404 for the F/A-18 Hornet, shortly after losing the competition for the F-15 Eagle's engine to Pratt & Whitney, and losing the Lightweight Fighter (LWF) competition to the Pratt & Whitney F100 powered YF-16. For the F/A-18, GE based the F404 on the YJ101 engine they had developed for the Northrop YF-17, enlarging the bypass ratio from .20 to .34 to enable higher fuel economy. The engine was designed with a higher priority on reliability than performance. Cost was the main goal in the design of the engine. GE also analyzed "throttle profiles" and found that pilots were changing throttle settings far more often than enginee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Malden River
The Malden River is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed April 1, 2011 river in Malden, Medford, and Everett, Massachusetts. It is roughly wide at its widest point and is very narrow at its smallest point. Its banks are largely occupied by industrial business, and the river is scarcely used or even mentioned. Its water quality is worse than most local waters, including the Mystic River, into which it flows. Most agree that the river is under-utilized. Projects like Rivers Edge (formerly TeleCom City) hope to promote recreational use of the river's banks. Currently, crew teams, including the Malden High School and the Mystic Valley Regional Charter School, practice on the river because it is never crowded like the Charles River. Also, a state-of-the-art boat house is located in Medford on the west bank of the river, used by the Tufts University rowing team. Course The above-ground portion of the Malde ...

Air Force Engineering And Services
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in ...

Nashua Telegraph
''The Telegraph'', for most of its existence known as the ''Nashua Telegraph'', is a daily newspaper in Nashua, New Hampshire. It was founded as the ''Nashua Daily Telegraph'' in 1869, although a weekly version dates back to 1832. Through the 2000s it was the second-largest newspaper in the state in terms of daily print circulation, behind the ''New Hampshire Union Leader'' of Manchester. In 2020 ''The Telegraph'' reduced its print run to Saturday only, when it produces a weekend edition under the ''Sunday Telegraph'' banner. In the announcement, the paper said it will continue to report news for its website every day. After being family-owned for a century, ''The Telegraph'' was bought in the 1980s by Independent Publications of Bryn Mawr, Pennsylvania, which owned several smaller daily and weekly newspapers around the United States as well as some other businesses.

Plants Of The United States Air Force
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...

Superfund Sites In Massachusetts
Superfund is a United States federal environmental remediation program established by the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). The program is administered by the Environmental Protection Agency (EPA). The program is designed to investigate and clean up sites contaminated with hazardous substances. Sites managed under this program are referred to as "Superfund" sites. There are 40,000 federal Superfund sites across the country, and approximately 1,300 of those sites have been listed on the National Priorities List (NPL). Sites on the NPL are considered the most highly contaminated and undergo longer-term remedial investigation and remedial action (cleanups). The EPA seeks to identify parties responsible for hazardous substances released to the environment (polluters) and either compel them to clean up the sites, or it may undertake the cleanup on its own using the Superfund (a trust fund) and seek to recover those costs from the ...
