Herndon, Virginia
Herndon is a town in Fairfax County, Virginia, in the Washington, D.C. metropolitan area of the United States. The population was 23,292 at the 2010 census. In 2020, the population was estimated to be 24,532, which makes it the largest of three incorporated towns in the county. The actual dimensions of the town of Herndon are fairly small. However, the United States Post Office treats nearby unincorporated communities in northwestern Fairfax County as part of a ''Greater Herndon'' region, including Dranesville, Floris, Franklin Farm, McNair, and Oak Hill. History The early settlement was named Herndon in 1858, after Commander William Lewis Herndon, an American naval explorer and author of ''Exploration of the Valley of the Amazon''. Commander Herndon captained the ill-fated steamer SS ''Central America'', going down with his ship while helping to save over 150 of its passengers and crew. In the 1870s, many Northern soldiers and their families came to settle in the area, tak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Semaphore Signal
Railway semaphore signal is one of the earliest forms of fixed railway signals. This semaphore system involves signals that display their different indications to train drivers by changing the angle of inclination of a pivoted 'arm'. Semaphore signals were patented in the early 1840s by Joseph James Stevens, and soon became the most widely used form of mechanical signal. Designs have altered over the intervening years, and colour light signals have replaced semaphore signals in most countries, but in a few they remain in use. Origins The first railway semaphore signal was erected by Charles Hutton Gregory on the London and Croydon Railway (later the London Brighton and South Coast Railway) at New Cross, southeast London, about 1842 on the newly enlarged layout also accommodating the South Eastern Railway. John Urpeth Rastrick claimed to have suggested the idea to Hutton Gregory. The semaphore was afterwards rapidly adopted as fixed manual signals throughout Britain and the ...

Eave
The eaves are the edges of the roof which overhang the face of a wall and, normally, project beyond the side of a building. The eaves form an overhang to throw water clear of the walls and may be highly decorated as part of an architectural style, such as the Chinese dougong bracket systems. Etymology and usage According to the ''Oxford English Dictionary'', ''eaves'' is derived from the Old English (singular), meaning "edge", and consequently forms both the singular and plural of the word. This Old English word is itself of Germanic origin, related to the German dialect ''Obsen'', and also probably to ''over''. The Merriam-Webster dictionary lists the word as ''eave'' but notes that it is "usually used in plural". Function The primary function of the eaves is to keep rain water off the walls and to prevent the ingress of water at the junction where the roof meets the wall. The eaves may also protect a pathway around the building from the rain, prevent erosion of the footin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victorian Architecture
Victorian architecture is a series of architectural revival styles in the mid-to-late 19th century. ''Victorian'' refers to the reign of Queen Victoria (1837–1901), called the Victorian era, during which period the styles known as Victorian were used in construction. However, many elements of what is typically termed "Victorian" architecture did not become popular until later in Victoria's reign, roughly from 1850 and later. The styles often included interpretations and eclectic revivals of historic styles ''(see Historicism)''. The name represents the British and French custom of naming architectural styles for a reigning monarch. Within this naming and classification scheme, it followed Georgian architecture and later Regency architecture, and was succeeded by Edwardian architecture. Although Victoria did not reign over the United States, the term is often used for American styles and buildings from the same period, as well as those from the British Empire. Victorian arc ...

Batten
A batten is most commonly a strip of solid material, historically wood but can also be of plastic, metal, or fiberglass. Battens are variously used in construction, sailing, and other fields. In the lighting industry, battens refer to linear light fittings. In the steel industry, battens used as furring may also be referred to as "top hats", in reference to the profile of the metal. Roofing ''Roofing battens'' or ''battening'', also called ''roofing lath'', are used to provide the fixing point for roofing materials such as shingles or tiles. The spacing of the battens on the trusses or rafters depend on the type of roofing material and are applied horizontally like purlins. Battens are also used in metal roofing to secure the sheets called a ''batten-seam roof'' and are covered with a ''batten roll joint''. Some roofs may use a grid of battens in both directions, known as a ''counter-batten system'', which improves ventilation. Roofing battens are most commonly made of ...

Runway
According to the International Civil Aviation Organization (ICAO), a runway is a "defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft". Runways may be a man-made surface (often asphalt concrete, asphalt, concrete, or a mixture of both) or a natural surface (sod, grass, soil, dirt, gravel, ice, sand or road salt, salt). Runways, as well as taxiways and Airport apron, ramps, are sometimes referred to as "tarmac", though very few runways are built using Tarmacadam, tarmac. Takeoff and landing areas defined on the surface of water for seaplanes are generally referred to as waterways. Runway lengths are now International Civil Aviation Organization#Use of the International System of Units, commonly given in meters worldwide, except in North America where feet are commonly used. History In 1916, in a World War I war effort context, the first concrete-paved runway was built in Clermont-Ferrand in France, allowing local company Michelin to ...

Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Before the 20th century, milking was done by hand on small farms. Beginning in the early 20th century, milking was done in large scale dairy farms with innovations including Rotary milking parlor, rotary parlors, the milking pipeline, and Automatic milking, automatic milking systems that were commercially developed in the early 1990s.
