Munsa
Munsa is an archaeological site in Uganda, located in the south-eastern part of Bunyoro (), and is commonly recognized by a rocky hill known by the locals as "Bikegete", which is enclosed within an earthworks system of ancient ditches. The site is approximately north-west of Kakumiro township in Bugangaizi County, Kakumiro District. "Munsa" is a Runyoro(Lunyoro/Runyoro Edited by Nicholas Aliganyira Nkuuna) name that means "in the trenches". The architects of the earthworks are unknown, although it has been speculated that the site can be linked to the Bachwezi. There is no evidence for this, however, and it seems likely that association of Munsa with the Bachwezi or Chwezi is a recent development. Excavations of this site have reconstructed the late-Holocene environmental history through evidence of iron-working, human burials, food production, and earthworks. While Bikigete may have been occupied as early as the 9th century AD, radiocarbon and luminescence dates obtained durin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archaeological Site
An archaeological site is a place (or group of physical sites) in which evidence of past activity is preserved (either prehistoric or historic or contemporary), and which has been, or may be, investigated using the discipline of archaeology and represents a part of the archaeological record. Sites may range from those with few or no remains visible above ground, to buildings and other structures still in use. Beyond this, the definition and geographical extent of a "site" can vary widely, depending on the period studied and the theoretical approach of the archaeologist. Geographical extent It is almost invariably difficult to delimit a site. It is sometimes taken to indicate a settlement of some sort although the archaeologist must also define the limits of human activity around the settlement. Any episode of deposition such as a hoard or burial can form a site as well. Development-led archaeology undertaken as cultural resources management has the disadvantage (or the be ...

Tuyere
A tuyere or tuyère (; ) is a tube, nozzle or pipe through which air is blown into a furnace or hearth.W. K. V. Gale, The iron and Steel industry: a dictionary of terms (David and Charles, Newton Abbot 1972), 216–217. Air or oxygen is injected into a hearth under pressure from bellows or a blowing engine or other devices. This causes the fire to be hotter in front of the blast than it would otherwise have been, enabling metals to be smelted or melted or made hot enough to be worked in a forge, though these are blown only with air. This applies to any process where a blast is delivered under pressure to make a fire hotter. The term (like many technical terms relating to ironmaking) was introduced to England from French with the new technology of the blast furnace and finery forge in around 1500, and was sometimes anglicised as tue-iron or tue iron. Following the introduction of hot blast, tuyeres are often water-cooled. Examples * A bloomery normally had one tu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archaeological Sites In Uganda
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic until the advent of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Empire Of Kitara
The Kingdom of the Banyakitara, also known as Union of Kitara (Union of Chwezi) or Chwezi Union, and better known as the Kitara Empire, was an empire in East Africa. It existed in the region from around the early bronze age to about 500 C.E. During its peak under the mysterious Chwezi Kings, the empire encompassed modern day Uganda, Eastern Kenya, eastern D.R. Congo, Rwanda, Burundi, Tanzania, Malawi, Zimbabwe and Angola. History According to oral traditions of western Uganda, the Kitara empire disintegrated during the 14th-15th centuries, and broke up into new autonomous kingdoms ruled by descendants of the Chwezi who, by oral legend, mysteriously vanished without a trace. The new kingdoms included Bunyoro, Tooro, Ankole, Buganda, Busoga in Uganda, the Kingdom of Rwanda, Burundi, and Karagwe in northern Tanzania and others in the eastern Democratic Republic of Congo. Kitara was reported to have been ruled by two dynasties, the Batembuzi gods and their successors the Bach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Slag
Slag is a by-product of smelting ( pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous/ base metals (by-products of recovering non-ferrous materials like copper, nickel, zinc and phosphorus). Within these general categories, slags can be further categorized by their precursor and processing conditions (e.g., Blast furnace (BF) slags, air-cooled blast furnace (ACBF) slag, basic oxygen furnace (BOF) slag, and electric arc furnace (EAF) slag) . Due to the large demand for these materials, slag production has also significantly increased throughout the years despite recycling (most notably in the iron and steelmaking industries) and upcycling efforts. The World Steel Association (WSA) estimates that 600 kg of by-products (~90 wt% is slags) are generated per tonne of steel produced. Composition Slag is usually a mixture of metal oxides and ...

Kuk Swamp
Kuk Swamp is an archaeological site in Papua New Guinea, that lies in the Wahgi Valley of the highlands. The swamp developed in a former lake basin, as it was filled by an alluvial fan or deposits of water-transported material. Archaeological evidence for early agricultural drainage systems was found here, beginning about 9,000 years ago. It includes draining ditches of three major classes, which were used to convert the area to an anthropogenic grassland. The native crop taro was grown here. In addition, evidence of cultivation of bananas and sugar cane has been found, estimated to have begun 6,900 – 6,400 years ago. The Kuk Swamp was recognized in 2008 as a World Heritage Site by UNESCO. It was one of the places in the world where people independently developed agriculture. Background The Kuk creek is believed to flow through the entirety of the fan to a catchment in the lower hills of the south region. Some channels were built to carry the water past the reach of the fan. If ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytolith
Phytoliths (from Greek, "plant stone") are rigid, microscopic structures made of silica, found in some plant tissues and persisting after the decay of the plant. These plants take up silica from the soil, whereupon it is deposited within different intracellular and extracellular structures of the plant. Phytoliths come in varying shapes and sizes. Although some use "phytolith" to refer to all mineral secretions by plants, it more commonly refers to siliceous plant remains. In contrast, mineralized calcium secretions in cacti are composed of calcium oxalates.Piperno, Dolores R. (2006). Phytoliths: A Comprehensive Guide for Archaeologists and Paleoecologists. AltaMira Press . The silica is absorbed in the form of monosilicic acid (Si(OH)4), and is carried by the plant's vascular system to the cell walls, cell lumen, and intercellular spaces. Depending on the plant taxa and soil condition, absorbed silica can range from 0.1% to 10% of the plant's total dry weight. When deposit ...

Core Sample
A core sample is a cylindrical section of (usually) a naturally-occurring substance. Most core samples are obtained by drilling with special drills into the substance, such as sediment or rock, with a hollow steel tube, called a core drill. The hole made for the core sample is called the "core hole". A variety of core samplers exist to sample different media under different conditions. More continue to be invented on a regular basis. In the coring process, the sample is pushed more or less intact into the tube. Removed from the tube in the laboratory, it is inspected and analyzed by different techniques and equipment depending on the type of data desired. Core samples can be taken to test the properties of manmade materials, such as concrete, ceramics, some metals and alloys, especially the softer ones. Core samples can also be taken of living things, including human beings, especially of a person's bones for microscopic examination to help diagnose diseases. Methods The co ...

Sherd
In archaeology, a sherd, or more precisely, potsherd, is commonly a historic or 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 ... fragment of pottery, although the term is occasionally used to refer to fragments of stone and glass vessels, as well. Occasionally, a piece of broken pottery may be referred to as a shard. While the spelling shard is generally reserved for referring to fragments of glass vessels, the term does not exclude pottery fragments. The etymology is connected with the idea of breakage, from Old English ''sceard'', related to Old Norse ''skarð'', "notch", and Middle High German ''schart'', "notch". A sherd or potsherd that has been used by having writing painted or inscribed on it can be more precisely referred to as an ostracon. The analys ...

El Niño–Southern Oscillation
El Niño–Southern Oscillation (ENSO) is an irregular periodic variation in winds and sea surface temperatures over the tropical eastern Pacific Ocean, affecting the climate of much of the tropics and subtropics. The warming phase of the sea temperature is known as ''El Niño'' and the cooling phase as ''La Niña''. The ''Southern Oscillation'' is the accompanying atmospheric component, coupled with the sea temperature change: ''El Niño'' is accompanied by high air surface pressure in the tropical western Pacific and ''La Niña'' with low air surface pressure there. The two periods last several months each and typically occur every few years with varying intensity per period. The two phases relate to the Walker circulation, which was discovered by Gilbert Walker during the early twentieth century. The Walker circulation is caused by the pressure gradient force that results from a high-pressure area over the eastern Pacific Ocean, and a low-pressure system over Indonesia. ...

Uganda
}), is a landlocked country in East Africa. The country is bordered to the east by Kenya, to the north by South Sudan, to the west by the Democratic Republic of the Congo, to the south-west by Rwanda, and to the south by Tanzania. The southern part of the country includes a substantial portion of Lake Victoria, shared with Kenya and Tanzania. Uganda is in the African Great Lakes region. Uganda also lies within the Nile basin and has a varied but generally a modified equatorial climate. It has a population of around 49 million, of which 8.5 million live in the capital and largest city of Kampala. Uganda is named after the Buganda kingdom, which encompasses a large portion of the south of the country, including the capital Kampala and whose language Luganda is widely spoken throughout the country. From 1894, the area was ruled as a protectorate by the United Kingdom, which established administrative law across the territory. Uganda gained independence from the UK on 9 Oc ...
