Erw
Welsh units of measurement are those in use in Wales between the Sub-Roman period (prior to which the Britons used Roman units) and the 13th-century Edwardian conquest (after which English units were imposed). Modern Wales no longer employs these units even for customary purposes but instead follows the custom as elsewhere in Britain of using a mixture of metric and Imperial units. Length In the Venedotian Code used in Gwynedd, the units of length were said to have been codified by Dyfnwal Moelmud but retained unchanged by Hywel Dda. The code provided for computing the units variously, as well as deriving them from grains of barley. In measuring milk and its legal worth ('), disputes over the length of the inch used in the container were to be resolved by the width of the judge's thumb. The code notes that in some areas of Wales, the rod used to compute the Welsh acre (') was not reckoned from feet but taken to be "as long as the tallest man in the ref with his hand above his hea ...

Wales ( cy, Cymru ) is a Countries of the United Kingdom, country that is part of the United Kingdom. It is bordered by England to the Wales–England border, east, the Irish Sea to the north and west, the Celtic Sea to the south west and the Bristol Channel to the south. It had a population in 2021 of 3,107,500 and has a total area of . Wales has over of coastline and is largely mountainous with its higher peaks in the north and central areas, including Snowdon (), its highest summit. The country lies within the Temperateness, north temperate zone and has a changeable, maritime climate. The capital and largest city is Cardiff. Welsh national identity emerged among the Celtic Britons after the Roman withdrawal from Britain in the 5th century, and Wales was formed as a Kingdom of Wales, kingdom under Gruffydd ap Llywelyn in 1055.

Venedotia
The Kingdom of Gwynedd (Medieval Latin: ; Middle Welsh: ) was a Welsh kingdom and a Roman Empire successor state that emerged in sub-Roman Britain in the 5th century during the Anglo-Saxon settlement of Britain. Based in northwest Wales, the rulers of Gwynedd repeatedly rose to dominance and were acclaimed as "King of the Britons" before losing their power in civil wars or invasions. The kingdom of Gruffydd ap Llywelynthe King of Wales from 1055 to 1063was shattered by a Saxon invasion in 1063 just prior to the Norman invasion of Wales, but the House of Aberffraw restored by Gruffudd ap Cynan slowly recovered and Llywelyn the Great of Gwynedd was able to proclaim the Principality of Wales at the Aberdyfi gathering of Welsh princes in 1216. In 1277, the Treaty of Aberconwy between Edward I of England and Llewelyn's grandson Llywelyn ap Gruffudd granted peace between the two but would also guarantee that Welsh self-rule would end upon Llewelyn's death, and so it represented th ...

Bleddyn ap Cynfyn ( owl, Bledẏnt uab Kẏnỽẏn; AD 1075), sometimes spelled Blethyn, was an 11th-century list of rulers of Wales, Welsh king. Harold Godwinson and Tostig Godwinson installed him and his brother, Rhiwallon ap Cynfyn, Rhiwallon, as the co-rulers of kingdom of Gwynedd, Gwynedd on his father's death in 1063, during their destruction of the kingdom of their half-brother, Gruffydd ap Llywelyn. Bleddyn became king of kingdom of Powys, Powys and co-ruler of the Kingdom of Gwynedd with his brother Rhiwallon from 1063 to 1075. His descendants continued to rule Powys as the House of Mathrafal. Background Bleddyn was born to a poorly documented Powys nobleman named Cynfyn ap Gwerystan, known only from the late traditional pedigrees reporting Bleddyn's parentage.

Milk
Milk is a white liquid food produced by the mammary glands of mammals. It is the primary source of nutrition for young mammals (including breastfed human infants) before they are able to digestion, digest solid food. Immune factors and immune-modulating components in milk contribute to milk immunity. Early-lactation milk, which is called colostrum, contains antibody, antibodies that strengthen the immune system, and thus reduces the risk of many diseases. Milk contains many nutrients, including protein and lactose. As an agricultural product, dairy milk is Milking, collected from farm animals. In 2011, Dairy farming, dairy farms produced around of milk from 260 million dairy cows. India is the world's largest producer of milk and the leading exporter of skimmed milk powder, but it exports few other milk products. Because there is an ever-increasing demand for dairy products within India, it could eventually become a net importer of dairy products. New Zealand, Germany and the ...

Cwmwd
A commote (Welsh ''cwmwd'', sometimes spelt in older documents as ''cymwd'', plural ''cymydau'', less frequently ''cymydoedd'')''Geiriadur Prifysgol Cymru'' (University of Wales Dictionary), p. 643 was a secular division of land in Medieval Wales. The word derives from the prefix ''cym-'' ("together", "with") and the noun ''bod'' ("home, abode"). The English word "commote" is derived from the Middle Welsh ''cymwt''. Medieval Welsh land organisation The basic unit of land was the ''tref'', a small village or settlement. In theory, 100 ''trefi'' made up a ''cantref'' (literally, "one hundred settlements"; plural: ''cantrefi''), and half or a third of a ''cantref'' was a ''cymwd'', although in practice the actual numbers varied greatly. Together with the ''cantrefi'', commotes were the geographical divisions through which defence and justice were organised. In charge of a commote would be a chieftain probably related to the ruling Prince of the Kingdom. His court would have been s ...

Maenor
The maenor (pl. ''maenorau'') was a gathering of villages in medieval Wales. In North Wales the word ''maenol'' was used for a similar, but not identical, idea. Although it is very often conflated with the English manor, ''maenor'' predates that Norman French term by centuries and is apparently etymologically unrelated, instead deriving from Welsh ''maen'' ("stone")Wade-Evans, Arthur. ''Welsh Medieval Law''. Oxford Univ., 1909. Accessed 1 Feb 2013. possibly originally describing the stone homes of local lords or the area sharing a single mill. Two kinds of ''maenorau'' were distinguished: those of the nobles and free yeomen (the ''maenor wrthdir'') and those of the serfs (the ''maenor vro''). According to the Laws of Hywel Dda, the ''maenor wrthdir'' comprised thirteen "free towns" (''trev ryd'') of 1248 Welsh acres each and the ''maenor vro'' seven "serftowns" (''taeogtrev'') of 936 Welsh acres each. By the late Medieval period, each town was considered to have its own smith, pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperial Units
The imperial system of units, imperial system or imperial units (also known as British Imperial or Exchequer Standards of 1826) is the system of units first defined in the British Weights and Measures Act 1824 and continued to be developed through a series of Weights and Measures Acts and amendments. The imperial system developed from earlier English units as did the related but differing system of customary units of the United States. The imperial units replaced the Winchester Standards, which were in effect from 1588 to 1825. The system came into official use across the British Empire in 1826. By the late 20th century, most nations of the former empire had officially adopted the metric system as their main system of measurement, but imperial units are still used alongside metric units in the United Kingdom and in some other parts of the former empire, notably Canada. The modern UK legislation defining the imperial system of units is given in the Weights and Measures Act ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Resistance Welding
Electric resistance welding (ERW) is a welding process where metal parts in contact are permanently joined by heating them with an electric current, melting the metal at the joint. Electric resistance welding is widely used, for example, in manufacture of steel pipe and in assembly of bodies for automobiles. The electric current can be supplied to electrodes that also apply clamping pressure, or may be induced by an external magnetic field. The electric resistance welding process can be further classified by the geometry of the weld and the method of applying pressure to the joint: spot welding, seam welding, flash welding, projection welding, for example. Some factors influencing heat or welding temperatures are the proportions of the workpieces, the metal coating or the lack of coating, the electrode materials, electrode geometry, electrode pressing force, electrical current and length of welding time. Small pools of molten metal are formed at the point of most electrical resista ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sub-Roman Britain
Sub-Roman Britain is the period of late antiquity in Great Britain between the end of Roman rule and the Anglo-Saxon settlement. The term was originally used to describe archaeological remains found in 5th- and 6th-century AD sites that hinted at the decay of locally made wares from a previous higher standard under the Roman Empire. It is now used to describe the period that commenced with the evacuation of Roman troops to Gaul by Constantine III in 407 and to have concluded with the Battle of Deorham in 577. Meaning of terms The period of sub-Roman Britain traditionally covers the history of the area which subsequently became England from the end of Roman imperial rule, traditionally dated to be in 410, to the arrival of Saint Augustine in 597. The date taken for the end of this period is arbitrary in that the sub-Roman culture continued in northern England until the merger of Rheged (the kingdom of the Brigantes) with Northumbria by dynastic marriage in 633, and longer i ...
