First Falls (Yarmouth, Maine)
The First Falls are the first of four waterfalls in Yarmouth, Maine, United States. They are located on the Royal River, approximately a mile from its mouth with inner Casco Bay at Yarmouth Harbor and around downstream of the Second Falls. The river appealed to settlers because its 45-foot rise in close proximity to navigable water each provided potential waterpower sites. As such, each of the four falls was used to power 57 mills between 1674 and the mid-20th century.''Ancient North Yarmouth and Yarmouth, Maine 1636-1936: A History'', William Hutchinson Rowe (1937) The local Native Americans called the First Falls (or '' Lower Falls'') ''Pumgustuk'', which means ''head of tide''. (The town's early firefighters were called Pumgustuk Fire Company. Their eponymous pumper was purchased in 1856 and retired in 1928.) Mills at the First Falls In addition to the 1674 sawmill of Englishman Henry Sayward and colonel Bartholomew Gedney (which became Walter Gendall's Casco Mill i ...

Yarmouth, Maine
Yarmouth is a town in Cumberland County, Maine, United States, twelve miles north of the state's largest city, Portland. When originally settled in 1636, as North Yarmouth, it was part of Massachusetts, and remained as such for 213 years. In 1849, twenty-nine years after Maine's admittance to the Union as the twenty-third state, it was incorporated as the Town of Yarmouth. Yarmouth is part of the Portland– South Portland-Biddeford Metropolitan Statistical Area. The town's population was 8,990 in the 2020 census. The town's proximity to the Atlantic Ocean, and its location on the banks of the Royal River (formerly ''Yarmouth River''), which empties into Casco Bay less than one mile away, means it is a prime location as a harbor. Ships were built in Yarmouth's harbor mainly between 1818 and the 1870s, at which point demand declined dramatically. Meanwhile, the Royal River's four waterfalls within Yarmouth, whose Main Street sits about above sea level, resulted in the foun ...

Wheat
Wheat is a grass widely cultivated for its seed, a cereal grain that is a worldwide staple food. The many species of wheat together make up the genus ''Triticum'' ; the most widely grown is common wheat (''T. aestivum''). The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around 9600 BCE. Botanically, the wheat kernel is a type of fruit called a caryopsis. Wheat is grown on more land area than any other food crop (, 2014). World trade in wheat is greater than for all other crops combined. In 2020, world production of wheat was , making it the second most-produced cereal after maize. Since 1960, world production of wheat and other grain crops has tripled and is expected to grow further through the middle of the 21st century. Global demand for wheat is increasing due to the unique viscoelastic and adhesive properties of gluten proteins, which facilitate the production of processed foods, whose consumption is inc ...

Superstructure
A superstructure is an upward extension of an existing structure above a baseline. This term is applied to various kinds of physical structures such as buildings, bridges, or ships. Aboard ships and large boats On water craft, the superstructure consists of the parts of the ship or a boat, including sailboats, fishing boats, passenger ships, and submarines, that project above her main deck. This does not usually include its masts or any armament turrets. Note that in modern times, turrets do not always carry naval artillery, but they can also carry missile launchers and/or antisubmarine warfare weapons. The size of a watercraft's superstructure can have many implications in the performance of ships and boats, since these structures can alter their structural rigidity, their displacements, and/or stability. These can be detrimental to any vessel's performance if they are taken into consideration incorrectly. The height and the weight of superstructure on board a ship or a bo ...

Rebar
Rebar (short for reinforcing bar), known when massed as reinforcing steel or reinforcement steel, is a steel bar used as a Tension (physics), tension device in reinforced concrete and reinforced masonry structures to strengthen and aid the concrete under tension. Concrete is strong under Compression (physics), compression, but has weak tensile strength. Rebar significantly increases the tensile strength of the structure. Rebar's surface features a continuous series of ribs, lugs or indentations to promote a better bond with the concrete and reduce the risk of slippage. The most common type of rebar is carbon steel, typically consisting of hot-rolled round bars with deformation patterns embossed into its surface. Steel and concrete have similar coefficient of thermal expansion, coefficients of thermal expansion, so a concrete structural member reinforced with steel will experience minimal differential stress (mechanics), stress as the temperature changes.

Pleasant Street (Yarmouth, Maine)
Pleasant Street is a historic street in Yarmouth, Maine, United States. It was formerly part of the Atlantic Highway (or New England Route 1), a precursor to U.S. Route 1. It connects to Lafayette Street, part of today's Maine State Route 88, at Pleasant Street’s southern and northern ends. It has existed since at least 1761, which is when a milestone was placed on the street, on the order of Benjamin Franklin, due to its being on the King's Highway, to denote its distance from Boston, Massachusetts. As part of his duties, Franklin conducted inspections of the roads that were used for delivering mail. One method of charging for mail service was by mileage, so Franklin invented an odometer to measure mileage more accurately. The King's Highway, as a result, morphed into the Post Road. In the mid-19th century, the street became the home of several notable sea captains, due to its proximity to Yarmouth Harbor at the northern end of the street. It is here that the road's elevati ...

Power Station
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a conductor creates an electric current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity. Low-carbon power sources include nuclear power, and an increasing use of renewables such as solar, wind, geothermal, and hydroelectric. History In early 1871 Belgian inventor Zénobe Gramme invented a generator powerful enough to produce power on a commercial scale for industry. In 1878, a hydroelectric power station was designed and built b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shipbuilding
Shipbuilding is the construction of ships and other floating vessels. It normally takes place in a specialized facility known as a shipyard. Shipbuilders, also called shipwrights, follow a specialized occupation that traces its roots to before recorded history. Shipbuilding and ship repairs, both commercial and military, are referred to as "naval engineering". The construction of boats is a similar activity called boat building. The dismantling of ships is called ship breaking. History Pre-history The earliest known depictions (including paintings and models) of shallow-water sailing boats is from the 6th to 5th millennium BC of the Ubaid period of Mesopotamia. They were made from bundled reeds coated in bitumen and had bipod masts. They sailed in shallow coastal waters of the Persian Gulf. 4th millennium BC Ancient Egypt Evidence from Ancient Egypt shows that the early Egyptians knew how to assemble planks of wood into a ship hull as early as 3100 BC. Egyptian potte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carpenter
Carpentry is a skilled trade and a craft in which the primary work performed is the cutting, shaping and installation of building materials during the construction of buildings, Shipbuilding, ships, timber bridges, concrete formwork, etc. Carpenters traditionally worked with natural wood and did rougher work such as framing, but today many other materials are also used and sometimes the finer trades of cabinetmaking and furniture building are considered carpentry. In the United States, 98.5% of carpenters are male, and it was the fourth most male-dominated occupation in the country in 1999. In 2006 in the United States, there were about 1.5 million carpentry positions. Carpenters are usually the first tradesmen on a job and the last to leave. Carpenters normally framed post-and-beam buildings until the end of the 19th century; now this old-fashioned carpentry is called timber framing. Carpenters learn this trade by being employed through an apprenticeship training—normally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interstate 295 (Maine)
Interstate 295 (I-295) is a auxiliary Interstate Highway in the US state of Maine from I-95 in Scarborough to I-95 in West Gardiner. The highway was designated the Richard A. Coleman Highway in 2015 by the Maine Legislature. The highway serves as a bypass of Lewiston–Auburn and serves the Portland metropolitan area. It takes a more direct route between Portland and Augusta, the state capital, than its parent I-95. It also is toll-free, unlike I-95, which carries the tolled Maine Turnpike. Route description I-295 branches off from exit 44 of I-95 (Maine Turnpike) providing access to downtown Portland, Maine, and then generally follows the Atlantic coast and Kennebec River until it merges back into I-95 in West Gardiner to the north at exit 103. After splitting from I-95, I-295 has a toll plaza just before its own exit 1. I-295's first exit is in South Portland, giving access to The Maine Mall (southbound) and South Portland and Scarborough (northbo ...
