The Bull Ring
The Bull Ring is a Class II henge that was built in the late Neolithic period near Dove Holes in Derbyshire, England. It has coordinates (), and is National Monument number 23282. There are also two barrows about 20m away from the henge; one oval, one bowl. The henge consists of a large, circular earthwork, which is currently about high and wide; however it was originally high and wide. The henge has a ditch on the inside, which varies between deep and wide; it was originally deep and wide. The ditch and bank are separated by a berm, which was originally wide. It encloses an area 53 (north–south) by 46 (east–west) metres, with entrances to the north and south, each of which have a causeway across the ditch. A skeleton was reputedly found near the north entrance; this entrance was also damaged in the 19th century by quarrying. The centre of the henge was ploughed in the 18th century; a drystone wall was also built across the site during the same era. A single s ...

Peak Forest Tramway
The Peak Forest Tramway was an early horse- and gravity-powered industrial railway (or tramway) system in Derbyshire, England. Opened for trade on 31 August 1796, it remained in operation until the 1920s. Much of the route and the structures associated with the line remain. The western section of the line is now the route of the Peak Forest Tramway Trail. The tramway was originally planned to be about long from Chapel Milton to Dove Holes. However, it was decided to start the tramway at Bugsworth (now called Buxworth) and, as built, it was about long. Its purpose was to carry limestone from the vast quarries around Dove Holes down to Bugsworth Basin via Chapel-en-le-Frith and Chinley, where much of it was taken by boat along the Peak Forest Canal and the Ashton Canal to Manchester and beyond. The remaining limestone was put into lime kilns at Bugsworth where it was converted into quick lime (or burnt lime). Construction Built by Benjamin Outram, the tramway was initially s ...

Protected Areas Of The United Kingdom
Protected areas of the United Kingdom are areas in the United Kingdom which need and /or receive protection because of their environmental, historical or cultural value to the nation. Methods and aims of protection vary depending on the nature and importance of the resource. Protection operates at local, regional, national and international levels, and may be backed by legislation and international treaty, or less formally by planning policy. Within the United Kingdom, different approaches are taken to some forms of protection within the constituent countries of England, Scotland, Wales and Northern Ireland, while other forms of protection are more consistent across the UK. Protected areas can be divided according to the type of resource which each seeks to protect. Primarily, these are: scenic or landscape value; biodiversity value (species and habitats); geodiversity value (relating to geology and geomorphology); and cultural or historic value. Several types of protected areas a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slit Trench
A defensive fighting position (DFP) is a type of earthwork constructed in a military context, generally large enough to accommodate anything from one soldier to a fire team (or similar sized unit). Terminology Tobruk type positions are named after the system of defensive positions constructed, initially, by the Italian Army at Tobruk, Libya. After Tobruk fell to the Allies in January 1941, the existing positions were modified and significantly expanded by the Australian Army which, along with other Allied forces, reused them in the Siege of Tobruk. A foxhole is one type of defensive strategic position. It is a "small pit used for cover, usually for one or two personnel, and so constructed that the occupants can effectively fire from it". It is known more commonly within United States Army slang as a "fighting position" or as a "ranger grave". It is known as a "fighting hole" in the United States Marine Corps, a "gun-pit" in Australian Army terminology, and a "fighting pit ...

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] |
Bowl Barrow
A bowl barrow is a type of burial mound or tumulus. A barrow is a mound of earth used to cover a tomb. The bowl barrow gets its name from its resemblance to an upturned bowl. Related terms include ''cairn circle'', ''cairn ring'', ''howe'', ''kerb cairn'', ''tump'' and ''rotunda grave''. Description Bowl barrows were created from the Neolithic through to the Bronze Age in Great Britain. A bowl barrow is an approximately hemispherical mound covering one or more Inhumations or cremations. Where the mound is composed entirely of stone, rather than earth, the term cairn replaces the word barrow. The mound may be simply a mass of earth or stone, or it may be structured by concentric rings of posts, low stone walls, or upright stone slabs. In addition, the mound may have a kerb of stones or wooden posts. Barrows were usually built in isolation in various situations on plains, valleys and hill slopes, although the most popular sites were those on hilltops. Bowl barrows were first ide ...

Bronze Age
The Bronze Age is a historic period, lasting approximately from 3300 BC to 1200 BC, characterized by the use of bronze, the presence of writing in some areas, and other early features of urban civilization. The Bronze Age is the second principal period of the three-age system proposed in 1836 by Christian Jürgensen Thomsen for classifying and studying ancient societies and history. An ancient civilization is deemed to be part of the Bronze Age because it either produced bronze by smelting its own copper and alloying it with tin, arsenic, or other metals, or traded other items for bronze from production areas elsewhere. Bronze is harder and more durable than the other metals available at the time, allowing Bronze Age civilizations to gain a technological advantage. While terrestrial iron is naturally abundant, the higher temperature required for smelting, , in addition to the greater difficulty of working with the metal, placed it out of reach of common use until the end o ...

Oval Barrow
An oval barrow is the name given by archaeologists to a type of prehistoric burial tumulus of roughly oval shape. In the British mid to late Neolithic and early Bronze Age, oval barrows may indicate a transition between earlier long barrows with multiple burials and the later, more individual round barrow A round barrow is a type of tumulus and is one of the most common types of archaeological monuments. Although concentrated in Europe, they are found in many parts of the world, probably because of their simple construction and universal purpose. ...s. Judging from those sited in or near the Thames Valley, there is much doubt as to how oval barrows are related to the burials found within them and funerary practices, because there can be a long gap of many years between an original burial and the construction of the barrow. Examples in England Buckinghamshire Whiteleaf Hill There is a neolithic oval barrow near the top of Whiteleaf Hill, Monks Risborough, Buckinghams ...

Electrical Resistance
The electrical resistance of an object is a measure of its opposition to the flow of electric current. Its reciprocal quantity is , measuring the ease with which an electric current passes. Electrical resistance shares some conceptual parallels with mechanical friction. The SI unit of electrical resistance is the ohm (), while electrical conductance is measured in siemens (S) (formerly called the 'mho' and then represented by ). The resistance of an object depends in large part on the material it is made of. Objects made of electrical insulators like rubber tend to have very high resistance and low conductance, while objects made of electrical conductors like metals tend to have very low resistance and high conductance. This relationship is quantified by resistivity or conductivity. The nature of a material is not the only factor in resistance and conductance, however; it also depends on the size and shape of an object because these properties are extensive rather than intens ...

Magnetometer
A magnetometer is a device that measures magnetic field or magnetic dipole moment. Different types of magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location. A compass is one such device, one that measures the direction of an ambient magnetic field, in this case, the Earth's magnetic field. Other magnetometers measure the magnetic dipole moment of a magnetic material such as a ferromagnet, for example by recording the effect of this magnetic dipole on the induced current in a coil. The first magnetometer capable of measuring the absolute magnetic intensity at a point in space was invented by Carl Friedrich Gauss in 1833 and notable developments in the 19th century included the Hall effect, which is still widely used. Magnetometers are widely used for measuring the Earth's magnetic field, in geophysical surveys, to detect magnetic anomalies of various types, and to determine the dipole moment of magnetic materials.
