History Of Sheffield
The history of Sheffield, a city in South Yorkshire, England, can be traced back to the founding of a settlement in a clearing beside the River Sheaf in the second half of the 1st millennium AD. The area now known as Sheffield had seen human occupation since at least the last ice age, but significant growth in the settlements that are now incorporated into the city did not occur until the Industrial Revolution. Following the Norman conquest of England, Sheffield Castle was built to control the Saxon settlements and Sheffield developed into a small town, no larger than Sheffield City Centre. By the 14th century Sheffield was noted for the production of knives, and by 1600, overseen by the Company of Cutlers in Hallamshire, it had become the second centre of cutlery production in England after London. In the 1740s the crucible steel process was improved by Sheffield resident Benjamin Huntsman, allowing a much better production quality. At about the same time, Sheffield plate ...

Economies Of Scale
In microeconomics, economies of scale are the cost advantages that enterprises obtain due to their scale of operation, and are typically measured by the amount of output produced per unit of time. A decrease in cost per unit of output enables an increase in scale. At the basis of economies of scale, there may be technical, statistical, organizational or related factors to the degree of market control. This is just a partial description of the concept. Economies of scale apply to a variety of the organizational and business situations and at various levels, such as a production, plant or an entire enterprise. When average costs start falling as output increases, then economies of scale occur. Some economies of scale, such as capital cost of manufacturing facilities and friction loss of transportation and industrial equipment, have a physical or engineering basis. The economic concept dates back to Adam Smith and the idea of obtaining larger production returns through the us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microliths
A microlith is a small stone tool usually made of flint or chert and typically a centimetre or so in length and half a centimetre wide. They were made by humans from around 35,000 to 3,000 years ago, across Europe, Africa, Asia and Australia. The microliths were used in spear points and arrowheads. Microliths are produced from either a small blade ( microblade) or a larger blade-like piece of flint by abrupt or truncated retouching, which leaves a very typical piece of waste, called a microburin. The microliths themselves are sufficiently worked so as to be distinguishable from workshop waste or accidents. Two families of microliths are usually defined: laminar and geometric. An assemblage of microliths can be used to date an archeological site. Laminar microliths are slightly larger, and are associated with the end of the Upper Paleolithic and the beginning of the Epipaleolithic era; geometric microliths are characteristic of the Mesolithic and the Neolithic. Geometric mic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Star Carr
Star Carr is a Mesolithic archaeological site in North Yorkshire, England. It is around five miles () south of Scarborough. It is generally regarded as the most important and informative Mesolithic site in Great Britain. It is as important to the Mesolithic period as Stonehenge is to the Neolithic period or Scandinavian York is to understanding Viking Age Britain. The site was occupied during the early Mesolithic archaeological period, which coincided with the preboreal and boreal climatic periods. Though the ice age had ended and temperatures were close to modern averages, sea levels had not yet risen sufficiently to separate Britain from continental Europe. Highlights among the finds include Britain’s oldest structure, 21 red deer stag skull-caps that may have been headdresses and nearly 200 projectile, or harpoon, points made of red deer antler. These organic materials were preserved due to having been buried in waterlogged peat. Normally all that remains on Mesolithic ...

Deepcar
Deepcar is a village located on the eastern fringe of the town of Stocksbridge, South Yorkshire, England. It is in the electoral ward of Stocksbridge and Upper Don, approximately north-west of Sheffield city centre.Ordnance survey. 1:25000. c.2012 Geography The village lies south-west of the confluence of the River Don and Little Don River, and near to the junctions of the A616 road and A6102 roads, and the former junction of the ' Woodhead Line' (Sheffield to Penistone section, built for the Sheffield, Ashton-under-Lyne and Manchester Railway) and private Stocksbridge Railways; the village was served by the Deepcar railway station from 1846 to 1959. History The Deepcar archaeological site, which included a structure or 'house', dating to the mesolithic period, and ascribed to the Maglemosian culture was excavated in 1962 close to the junction of the Don and Little Don at Wharncliffe Wood. (). The site's culture has similarities to Star Carr in North Yorkshire, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesolithic
The Mesolithic ( Greek: μέσος, ''mesos'' 'middle' + λίθος, ''lithos'' 'stone') or Middle Stone Age is the Old World archaeological period between the Upper Paleolithic and the Neolithic. The term Epipaleolithic is often used synonymously, especially for outside northern Europe, and for the corresponding period in the Levant and Caucasus. The Mesolithic has different time spans in different parts of Eurasia. It refers to the final period of hunter-gatherer cultures in Europe and Western Asia, between the end of the Last Glacial Maximum and the Neolithic Revolution. In Europe it spans roughly 15,000 to 5,000 BP; in Southwest Asia (the Epipalaeolithic Near East) roughly 20,000 to 10,000 BP. The term is less used of areas farther east, and not at all beyond Eurasia and North Africa. The type of culture associated with the Mesolithic varies between areas, but it is associated with a decline in the group hunting of large animals in favour of a broader hunter-g ...

Prehistoric
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Ir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Palaeolithic
The Upper Paleolithic (or Upper Palaeolithic) is the third and last subdivision of the Paleolithic or Old Stone Age. Very broadly, it dates to between 50,000 and 12,000 years ago (the beginning of the Holocene), according to some theories coinciding with the appearance of behavioral modernity in early modern humans, until the advent of the Neolithic Revolution and agriculture. Anatomically modern humans (i.e. ''Homo sapiens'') are believed to have emerged in Africa around 300,000 years ago, it has been argued by some that their ways of life changed relatively little from that of archaic humans of the Middle Paleolithic, until about 50,000 years ago, when there was a marked increase in the diversity of Artefact (archaeology), artefacts found associated with modern human remains. This period coincides with the most common date assigned to early human migrations, expansion of modern humans from Africa throughout Asia and Eurasia, which contributed to the Neanderthal extinction, ex ...

Creswell Crags
Creswell Crags is an enclosed limestone gorge on the border between Derbyshire and Nottinghamshire, England, near the villages of Creswell and Whitwell. The cliffs in the ravine contain several caves that were occupied during the last ice age, between around 43,000 and 10,000 years ago. Its caves contain the northernmost cave art in Europe. The evidence of occupation found in the rich series of sediments that accumulated over many thousands of years is regarded as internationally unique in demonstrating how prehistoric people managed to live at the extreme northernmost limits of their territory during the Late Pleistocene period. The caves contain occupation layers with evidence of flint tools from the Mousterian, proto- Solutrean, Creswellian and Maglemosian cultures. They were seasonally occupied by nomadic groups of people during the Upper Palaeolithic and Mesolithic periods. Evidence of Neolithic, Bronze Age, Roman and post-medieval activity has also been found there. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
