Rhydymwyn
Rhydymwyn (the name in Welsh means 'Ford of the Ore' and takes its placename from the ford across the River Alyn now replaced by a small iron bridge) is a village in Flintshire, Wales, located in the upper Alyn valley. Once a district of Mold, it was recognised as a separate parish from 1865. It is now part of the community of Cilcain. Geography The geology of the area consists of a layer of extremely pure, and hence structurally sound, thick layer of limestone at depths ranging from surface to . The limestone holds other minerals, including nickel and copper deposits, making it an ideal site for mining. History Due to the industrialisation of nearby Northwest England, and its needs for mineral supplies, the mineral deposits in the Alyn valley created a population explosion in various villages, including Rhydymwyn. From the mid-18th century, Rhydymwyn was the site for a range of industries, which included foundries, waterwheels as well as mine workings. The new parish of Rhydy ...

Mustard Gas
Mustard gas or sulfur mustard is a chemical compound belonging to a family of cytotoxic and blister agents known as mustard agents. The name ''mustard gas'' is technically incorrect: the substance, when dispersed, is often not actually a gas, but is instead in the form of a fine mist of liquid droplets.https://www.acs.org/content/dam/acsorg/education/resources/highschool/chemmatters/gc-mustard-gas-personal-safety-and-natl-security.pdf Mustard gases form blisters on exposed skin and in the lungs, often resulting in prolonged illness ending in death. The active ingredient in typical mustard gas is the organosulfur compound bis(2-chloroethyl) sulfide. In the wider sense, compounds with the structural element are known as ''sulfur mustards'' and ''nitrogen mustards'', respectively. Such compounds are potent alkylating agents, which can interfere with several biological processes. History as chemical weapons As a chemical weapon, mustard gas was first used in World War I, and has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Denbigh And Mold Junction Railway
The Mold and Denbigh Junction Railway was a railway company that built a railway line in North Wales. It formed a link between the Mold Railway (from Chester) and the Vale of Clwyd Railway towards Rhyl. The line opened in 1869. Serving a largely rural district, it never attracted much business, and the passenger service was withdrawn in 1962. Ordinary goods traffic ceased not long after, and the line closed completely in 1983. Conception The Chester and Holyhead Railway was opened throughout in 1850,Peter E Baughan, ''A Regional History of the Railways of Great Britain: 14: North and Mid Wales'', David St John Thomas, Nairn, 1991, , pages 22 and 24 and it was absorbed by the London and North Western Railway in 1858. The Great Western Railway was the principal competitor of the LNWR in the area, and the GWR had taken steps to reach Rhyl, an important regional centre. It hoped to do this by taking control of a series of local railways, northwards from the Vale of Llangollen Railw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cilcain
Cilcain is a village and community, near Mold in Flintshire, north-east Wales. The village has an industrial history and includes the Millennium Woods, a post office, a public house, a parish church, a primary school (Ysgol y Foel) and a village hall. Cilcain borders the parishes of Rhosesmor, Rhes-y-cae and Rhydymwyn. The community includes the village of Rhydymwyn. Name The Welsh placename Cilcain, which has also in the past been spelled as Kilken and Cilcen, has been suggested to derive from ''cil'' meaning 'retreat' and ''cain'' meaning 'fair' or 'pleasant' in the Welsh language.

River Alyn
The River Alyn ( cy, Afon Alun) is a tributary of the River Dee, in north-east Wales. The River Alyn rises at the southern end of the Clwydian hills and the Alyn Valley forms part of the Clwydian Range and Dee Valley Area of Outstanding Natural Beauty. The main town on the river is Mold, the county town of Flintshire. It lends its name to the constituencies of Alyn and Deeside in the UK Parliament and the Senedd. The River Alyn crosses the carboniferous limestone from Halkyn Mountain and north through the Loggerheads area before heading southeast, passing through Mold before reaching its confluence with the River Dee to the northeast of Wrexham. Between Loggerheads and Rhydymwyn it runs through the Alyn Gorge, which is the site of the caves Ogof Hesp Alyn, Ogof Hen Ffynhonnau and Ogof Nadolig. The river mainly runs across a limestone surface, creating potholes and underwater caves, into which the river flows through some of the summer, when water levels have decreased si ...

Tube Alloys
Tube Alloys was the research and development programme authorised by the United Kingdom, with participation from Canada, to develop nuclear weapons during the Second World War. Starting before the Manhattan Project in the United States, the British efforts were kept classified, and as such had to be referred to by code even within the highest circles of government. The possibility of nuclear weapons was acknowledged early in the war. At the University of Birmingham, Rudolf Peierls and Otto Robert Frisch co-wrote a memorandum explaining that a small mass of pure uranium-235 could be used to produce a chain reaction in a bomb with the power of thousands of tons of TNT. This led to the formation of the MAUD Committee, which called for an all-out effort to develop nuclear weapons. Wallace Akers, who oversaw the project, chose the deliberately misleading code name "Tube Alloys". His Tube Alloys Directorate was part of the Department of Scientific and Industrial Research.

Delyn (Assembly Constituency)
Delyn is a constituency of the Senedd. It elects one Member of the Senedd by the first past the post method of election. Also, however, it is one of nine constituencies in the North Wales electoral region, which elects four additional members, in addition to nine constituency members, to produce a degree of proportional representation for the region as a whole. Boundaries The constituency was created for the first election to the Assembly, in 1999, with the name and boundaries of the Delyn Westminster constituency.

Industrialisation
Industrialisation ( alternatively spelled industrialization) is the period of social and economic change that transforms a human group from an agrarian society into an industrial society. This involves an extensive re-organisation of an economy for the purpose of manufacturing. Historically industrialization is associated with increase of polluting industries heavily dependent on fossil fuels. With the increasing focus on sustainable development and green industrial policy practices, industrialization increasingly includes technological leapfrogging, with direct investment in more advanced, cleaner technologies. The reorganization of the economy has many unintended consequences both economically and socially. As industrial workers' incomes rise, markets for consumer goods and services of all kinds tend to expand and provide a further stimulus to industrial investment and economic growth. Moreover, family structures tend to shift as extended families tend to no longer live ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dee Estuary
The Dee Estuary ( cy, Aber Dyfrdwy) is a large estuary by means of which the River Dee flows into Liverpool Bay. The estuary starts near Shotton after a five-mile (8 km) 'canalised' section and the river soon swells to be several miles wide forming the boundary between the Wirral Peninsula in north-west England and Flintshire in north-east Wales. The Dee Estuary's largest towns along it include Hollywell, Flint, Connah's Quay, Shotton, Queensferry, Saltney Ferry, Chester (City), Heswall, West Kirby and Neston as well as other villages and towns alongside it. The A548 also passes along the estuary in Wales and parts of Cheshire West and Chester and Merseyside in England. The North Wales Coast Line follows the course of the Dee Estuary between Prestatyn and Chester. Geology The estuary is unusual in that comparatively little water occupies so large a basin. One theory is that larger rivers such as the Severn and/or Mersey once flowed into the Dee. The current view is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quebec Agreement
The Quebec Agreement was a secret agreement between the United Kingdom and the United States outlining the terms for the coordinated development of the science and engineering related to nuclear energy and specifically nuclear weapons. It was signed by Winston Churchill and Franklin D. Roosevelt on 19 August 1943, during World War II, at the First Quebec Conference in Quebec City, Quebec, Canada. The Quebec Agreement stipulated that the US and UK would pool their resources to develop nuclear weapons, and that neither country would use them against the other, or against other countries without mutual consent, or pass information about them to other countries. It also gave the United States a veto over post-war British commercial or industrial uses of nuclear energy. The agreement merged the British Tube Alloys project with the American Manhattan Project, and created the Combined Policy Committee to control the joint project. Although Canada was not a signatory, the Agreement ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atomic Bomb
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been deployed ...
