Aia
Aia (; ) is a village situated on the slopes of Mount Pagoeta in the Basque province of Gipuzkoa, Spain. It is located 30 km to the west of Donostia-San Sebastián and about 10 km inland from the coastal town of Zarautz. Aia is set amongst hills and forests, and surrounded by mountains. The town has a large church, the Church of San Esteban, which includes a notable centrepiece. The population of Aia has gradually declined since the 1950s, to a population of 1,750 in 2005. History Based on cave paintings and engravings and also stone implements that have been found in the Aia district, it is believed that human habitation of the area dates back to over 10,000 years ago. The town of Aia itself was mentioned in one of the oldest documents of Gipuzkoa dated 1025. The town was also mentioned as being part of the Union of Sayaz in the Decree of the Brotherhood of the Province of Gupuzkoa in 1375. Farming was originally the main economic activity in the Aia district, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Municipalities Of Spain
The municipality ( es, municipio, , ca, municipi, gl, concello, eu, udalerria, ast, conceyu)In other languages of Spain: * Catalan/Valencian (), sing. ''municipi''. * Galician () or (), sing. ''municipio''/''bisbarra''. *Basque (), sing. ''udalerria''. * Asturian (), sing. ''conceyu''. is the basic local administrative division in Spain together with the province. Organisation Each municipality forms part of a province which in turn forms part or the whole of an autonomous community (17 in total plus Ceuta and Melilla): some autonomous communities also group municipalities into entities known as ''comarcas'' (districts) or ''mancomunidades'' (commonwealths). There are a total of 8,131 municipalities in Spain, including the autonomous cities of Ceuta and Melilla. In the Principality of Asturias, municipalities are officially named ''concejos'' (councils). The average population of a municipality is about 5,300, but this figure masks a huge range: the most populo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron
Iron () is a chemical element with symbol Fe (from la, ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites. Iron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or furnaces capable of reaching or higher, about higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BCE and the use of iron tools and weapons began to displace copper alloys, in some regions, only around 1200 BCE. That event is considered the transition from the Bronze Age to the Iron A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bellows
A bellows or pair of bellows is a device constructed to furnish a strong blast of air. The simplest type consists of a flexible bag comprising a pair of rigid boards with handles joined by flexible leather sides enclosing an approximately airtight cavity which can be expanded and contracted by operating the handles, and fitted with a valve allowing air to fill the cavity when expanded, and with a tube through which the air is forced out in a stream when the cavity is compressed. xford English Dictionary, 2nd ed: bellows/ref> It has many applications, in particular blowing on a fire to supply it with air. The term "bellows" is used by extension for a flexible bag whose volume can be changed by compression or expansion, but not used to deliver air. For example, the light-tight (but not airtight) bag allowing the distance between the lens and film of a folding photographic camera to be varied is called a bellows. Etymology "Bellows" is only used in plural. The Old English name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydropower
Hydropower (from el, ὕδωρ, "water"), also known as water power, is the use of falling or fast-running water to Electricity generation, produce electricity or to power machines. This is achieved by energy transformation, converting the Potential energy, gravitational potential or kinetic energy of a water source to produce power. Hydropower is a method of sustainable energy production. Hydropower is now used principally for Hydroelectricity, hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce Carbon dioxide in Earth's atmosphere, carbon dioxide or other Air pollution, atmospheric pollutants and it provides a relatively consistent source of power. Nonetheless, it has economic, sociological, and environmental downsides and requires a sufficiently energetic source of water, such as a river or elevated lake. Int ...

Agorregi Forge
The Agorregi Forge is located within the Pagoeta Nature Reserve, near the town of Aia, in the Basque Province of Gipuzkoa, Spain. It is one of the best preserved examples of a foundry in Gipuzkoa province. The forge which can be seen today is a built in 1754 by the lord of Laurgain Palace over the ruins of an earlier version. Lying at the bottom of a deep valley near Manterola farmhouse, it used the river's hydraulic energy Hydropower (from el, ὕδωρ, "water"), also known as water power, is the use of falling or fast-running water to produce electricity or to power machines.

Burial Mound
Burial, also known as interment or inhumation, is a method of final disposition whereby a dead body is placed into the ground, sometimes with objects. This is usually accomplished by excavating a pit or trench, placing the deceased and objects in it, and covering it over. A funeral is a ceremony that accompanies the final disposition. Humans have been burying their dead since shortly after the origin of the species. Burial is often seen as indicating respect for the dead. It has been used to prevent the odor of decay, to give family members closure and prevent them from witnessing the decomposition of their loved ones, and in many cultures it has been seen as a necessary step for the deceased to enter the afterlife or to give back to the cycle of life. Methods of burial may be heavily ritualized and can include natural burial (sometimes called "green burial"); embalming or mummification; and the use of containers for the dead, such as shrouds, coffins, grave liners, and bu ...

Pagoeta Nature Reserve
Pagoeta Natural Park is a park in Spain. Mount Pagoeta is closest to the villages of Aia and Laurgain, and near the coastal towns of Zarautz and Orio, Spain, Orio. The park features a park house, a museum, and picnic areas. Group guided tours are available. Features The natural park, covering an area of 2,860 hectares, was created by the agricultural activities of the village and differs from many parks for that reason. Instead of demonstrating only natural landscape, it shows the impact of human intervention in the environment. For example, installations remain throughout the park for making charcoal from wood and the water-powered Aborregi forge has been reconstructed. In addition to demonstrating historical practices, the park continues to display human intervention in the environment, with reforestation and the formation of an exotic species botanical garden. There are also archaeological remnants of the prehistoric occupants of the area, with dolmens, Tumulus, barrows and ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blast Furnace
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. ''Blast'' refers to the combustion air being "forced" or supplied above atmospheric pressure. In a blast furnace, fuel ( coke), ores, and flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with oxygen enrichment) is blown into the lower section of the furnace through a series of pipes called tuyeres, so that the chemical reactions take place throughout the furnace as the material falls downward. The end products are usually molten metal and slag phases tapped from the bottom, and waste gases (flue gas) exiting from the top of the furnace. The downward flow of the ore along with the flux in contact with an upflow of hot, carbon monoxide-rich combustion gases is a countercurrent exchange and chemical reaction process. In contrast, air furnaces (such as reverbera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
