Underground Cable
In civil engineering, undergrounding is the replacement of overhead cables providing electric power, electrical power or telecommunications, with underground cables. It helps in wildfire prevention and in making the power lines less susceptible to Power outage, outages during high winds, thunderstorms or heavy snow or ice storms. An added benefit of undergrounding is the aesthetic quality of the landscape without the powerlines. Undergrounding can increase the capital cost of electric power transmission and Electric power distribution, distribution but may decrease operating costs over the lifetime of the cables. History Early undergrounding had a basis in the detonation of mining explosives and in undersea telegraph cables. Electric cables were used in Russia to detonate mining explosives in 1812, and to carry telegraph signals across the English Channel in 1850. With the spread of early electrical power systems, undergrounding began to increase as well. Thomas Edison used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lightning
Lightning is a naturally occurring electrostatic discharge during which two electric charge, electrically charged regions, both in the atmosphere or with one on the land, ground, temporarily neutralize themselves, causing the instantaneous release of an average of one Joule, gigajoule of energy. This discharge may produce a wide range of electromagnetic radiation, from heat created by the rapid movement of electrons, to brilliant flashes of visible light in the form of black-body radiation. Lightning causes thunder, a sound from the shock wave which develops as gases in the vicinity of the discharge experience a sudden increase in pressure. Lightning occurs commonly during thunderstorms as well as other types of energetic weather systems, but volcanic lightning can also occur during volcanic eruptions. The three main kinds of lightning are distinguished by where they occur: either inside a single Cumulonimbus cloud, thundercloud (intra-cloud), between two clouds (cloud-to-cl ...

Dorset AONB
Dorset (or archaically, Dorsetshire) is a county in South West England on the English Channel coast. Covering an area of ; it borders Devon to the west, Somerset to the north-west, Wiltshire to the north-east, and Hampshire to the east. The great variation in its landscape owes much to the underlying geology, which includes an almost unbroken sequence of rocks from 200 to 40 million years ago (Mya) and superficial deposits from 2 Mya to the present.Chaffey (pp.5–6) In general, the oldest rocks (Early Jurassic) appear in the far west of the county, with the most recent (Eocene) in the far east. Jurassic rocks also underlie the Blackmore Vale and comprise much of the coastal cliff in the west and south of the county; although younger Cretaceous rocks crown some of the highpoints in the west, they are mainly to be found in the centre and east of the county.Chaffey (p.6) Dorset's coastline is one of the most visited and studied coastlines in the world because it shows, along the c ...

Weymouth, Dorset
Weymouth is a seaside town in Dorset, on the English Channel coast of England. Situated on a sheltered bay at the mouth of the River Wey, south of the county town of Dorchester, Weymouth had a population of 53,427 in 2021. It is the third largest settlement in Dorset after Bournemouth and Poole. The history of the town stretches back to the 12th century and includes roles in the spread of the Black Death, the settlement of the Americas and the development of Georgian architecture. It was a major departure point for the Normandy Landings during World War II. Prior to local government reorganisation in April 2019, Weymouth formed a borough with the neighbouring Isle of Portland. Since then the area has been governed by Dorset Council. Weymouth, Portland and the Purbeck district are in the South Dorset parliamentary constituency. A seaside resort, Weymouth and its economy depend on tourism. Visitors are attracted by its harbour and position, halfway along the Jurassic Coast ...

Friar Waddon
A friar is a member of one of the mendicant orders founded in the twelfth or thirteenth century; the term distinguishes the mendicants' itinerant apostolic character, exercised broadly under the jurisdiction of a superior general, from the older monastic orders' allegiance to a single monastery formalized by their vow of stability. A friar may be in holy orders or a brother. The most significant orders of friars are the Dominicans, Franciscans, Augustinians, and Carmelites. Definition Friars are different from monks in that they are called to live the evangelical counsels (vows of poverty, chastity, and obedience) in service to society, rather than through cloistered asceticism and devotion. Whereas monks live in a self-sufficient community, friars work among laypeople and are supported by donations or other charitable support. Monks or nuns make their vows and commit to a particular community in a particular place. Friars commit to a community spread across a wider geograp ...

Winterbourne Abbas
Winterborne Abbas is a village and civil parish in south west Dorset, England, situated in a valley on the A35 road west of Dorchester. In the 2011 census the parish had a population of 355. The village Winterbourne Abbas is a pleasant rural village, only spoilt by the heavy traffic which passes through on the A35. The Coach and Horses Inn dates from 1814 or earlier and was a coaching inn on the turnpike road from Dorchester to Bridport. The Baptist Chapel dates from 1872 and has been converted to residential use. Other notable buildings include the Old Post Office in the middle of a terrace of cottages and the Grange. The Nine Stones stone circle lies just to the west of the village just to the south of the A35 road and surrounded by trees. It is probably the best example of a stone circle in Dorset. Also near the village are the remains of various ancient barrows and burial chambers, including Poor Lot Barrow Cemetery. The church The parish church is dedicated to St Mar ...

Areas Of Outstanding Natural Beauty
An Area of Outstanding Natural Beauty (AONB; , AHNE) is an area of countryside in England, Wales, and Northern Ireland, that has been designated for conservation due to its significant landscape value. Areas are designated in recognition of their national importance by the relevant public body: Natural England, Natural Resources Wales, and the Northern Ireland Environment Agency respectively. In place of AONB, Scotland uses the similar national scenic area (NSA) designation. Areas of Outstanding Natural Beauty enjoy levels of protection from development similar to those of UK national parks, but unlike national parks the responsible bodies do not have their own planning powers. They also differ from national parks in their more limited opportunities for extensive outdoor recreation. History The idea for what would eventually become the AONB designation was first put forward by John Dower in his 1945 ''Report to the Government on National Parks in England and Wales''. Dower ...

Utility Trench In Bwy @ 42 St Jeh
As a topic of economics, utility is used to model worth or Value (economics), value. Its usage has evolved significantly over time. The term was introduced initially as a measure of pleasure or happiness as part of the theory of utilitarianism by moral philosophers such as Jeremy Bentham and John Stuart Mill. The term has been adapted and reapplied within neoclassical economics, which dominates modern economic theory, as a utility function that represents a single consumer's preference ordering over a choice set but is not comparable across consumers. This concept of utility is personal and based on choice rather than on pleasure received, and so is specified more rigorously than the original concept but makes it less useful (and controversial) for ethical decisions. Utility function Consider a set of alternatives among which a person can make a preference ordering. The utility obtained from these alternatives is an unknown function of the utilities obtained from each alternat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liquefaction
In materials science, liquefaction is a process that generates a liquid from a solid or a gas or that generates a non-liquid phase which behaves in accordance with fluid dynamics. It occurs both naturally and artificially. As an example of the latter, a "major commercial application of liquefaction is the liquefaction of air to allow separation of the constituents, such as oxygen, nitrogen, and the noble gases." Another is the conversion of solid coal into a liquid form usable as a substitute for liquid fuels. Geology In geology, soil liquefaction refers to the process by which water-saturated, unconsolidated sediments are transformed into a substance that acts like a liquid, often in an earthquake. Soil liquefaction was blamed for building collapses in the city of Palu, Indonesia in October 2018. In a related phenomenon, liquefaction of bulk materials in cargo ships may cause a dangerous shift in the load. Physics and chemistry In physics and chemistry, the phase transiti ...

2011 Christchurch Earthquake
A major earthquake occurred in Christchurch on Tuesday 22 February 2011 at 12:51 p.m. local time (23:51 UTC, 21 February). The () earthquake struck the entire of the Canterbury region in the South Island, centred south-east of the central business district. It caused widespread damage across Christchurch, killing 185 people, in New Zealand's fifth-deadliest disaster. Christchurch's central city and eastern suburbs were badly affected, with damage to buildings and infrastructure already weakened by the magnitude 7.1 Canterbury earthquake of 4 September 2010 and its aftershocks. Significant liquefaction affected the eastern suburbs, producing around 400,000 tonnes of silt. The earthquake was felt across the South Island and parts of the lower and central North Island. While the initial quake only lasted for approximately 10 seconds, the damage was severe because of the location and shallowness of the earthquake's focus in relation to Christchurch as well as ...
