Jebel Moya
Jebel Moya is an archaeological site in the southern Gezira Plain, Sudan, approximately 250 km (150 miles) south southeast of Khartoum. Dating between 5000 BCE-500 CE and roughly 104,000 m2 (25 acres) in area, the site is one of the largest pastoralist cemeteries in Africa with over 3,000 burials excavated thus far. The site was first excavated by Sir Henry Wellcome from 1911 to 1914. Artifacts found at the site suggest trade routes between Jebel Moya and its surrounding areas, even as far as Egypt. Environment The Gezira Plain is a megafan created by the Blue Nile. Present day flood levels were in place by 3500 BCE, as the area transitioned from swampy conditions to a savanna as the Inter Tropical Convergence Zone moved south. The environmental transition from swamp to savanna and semi-desert steppe was complete by 3000 BCE. By the early centuries CE, few swampy conditions remained; one notable wet site that remained is Jebel et Tomat, another early pastoralist site, ...

Sir Henry Wellcome
Sir Henry Solomon Wellcome (August 21, 1853 – July 25, 1936) was an American pharmaceutical entrepreneur. He founded the pharmaceutical company Burroughs Wellcome & Company with his colleague Silas Burroughs in 1880, which is one of the four large companies to eventually merge to form GlaxoSmithKline. He left a large amount of capital for charitable work in his will, which was used to form the Wellcome Trust, one of the world's largest medical charities. He was a keen collector of medical artefacts which are now displayed at the Wellcome Collection. Biography Wellcome was born in a frontier log cabin in what would later become Almond, Wisconsin, to Rev. S. C. Wellcome, an itinerant missionary who travelled and preached in a covered wagon, and Mary Curtis Wellcome. He had an early interest in medicine, particularly marketing. His first product, at the age of 16, was invisible ink (in fact just lemon juice), which he advertised in the Garden City (MN) Herald. He was brought ...

Optically Stimulated Luminescence
In physics, optically stimulated luminescence (OSL) is a method for measuring doses from ionizing radiation. It is used in at least two applications: * Luminescence dating of ancient materials: mainly geological sediments and sometimes fired pottery, bricks etc., although in the latter case thermoluminescence dating is used more often * Radiation dosimetry, which is the measurement of accumulated radiation dose in the tissues of health care, nuclear, research and other workers, as well as in building materials in regions of nuclear disaster The method makes use of electrons trapped between the valence and conduction bands in the crystalline structure of certain minerals (most commonly quartz and feldspar). The trapping sites are imperfections of the lattice — impurities or defects. The ionizing radiation produces electron-hole pairs: Electrons are in the conduction band and holes in the valence band. The electrons that have been excited to the conduction band may become entr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Neolithic Infant Feeding Cup, Africa, 1000 BCE-400 BCE Wellcome L0057861
The Neolithic period, or New Stone Age, is an Old World archaeological period and the final division of the Stone Age. It saw the Neolithic Revolution, a wide-ranging set of developments that appear to have arisen independently in several parts of the world. This "Neolithic package" included the introduction of farming, domestication of animals, and change from a hunter-gatherer lifestyle to one of settlement. It began about 12,000 years ago when farming appeared in the Epipalaeolithic Near East, and later in other parts of the world. The Neolithic lasted in the Near East until the transitional period of the Chalcolithic (Copper Age) from about 6,500 years ago (4500 BC), marked by the development of metallurgy, leading up to the Bronze Age and Iron Age. In other places the Neolithic followed the Mesolithic (Middle Stone Age) and then lasted until later. In Ancient Egypt, the Neolithic lasted until the Protodynastic period, 3150 BC.Karin Sowada and Peter Grave. Egypt i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rabak
Rabak (ربك) is a city in south-eastern Sudan and the capital of the Sudanese state of White Nile. It is one of the major cities of Sudan, an industrial city in which are located several factories, such as the Nile Cement Company factory, the Kenana sugar factory, and the Assalaya sugar factory. Geography The city is located on the eastern bank of the White Nile, facing Kosti on the western bank. It lies some 362 meters above sea level. Rabak is approximately south of Khartoum and west of the Ethiopian border. It is linked to the north of Sudan via the Khartoum–Rabak road; and it is linked by road eastward to Sennar and westward to Al-Ubayyid. Climate Rabak has a hot arid climate (Köppen climate classification ''BWh''), despite receiving over of rainfall annually, owing to the extremely high potential evapotranspiration. Demographics History Rabak was made the capital of the White Nile State in 1994. Economy Rabak is one of major commercial cities in Sudan o ...

Jujube
Jujube (), sometimes jujuba, known by the scientific name ''Ziziphus jujuba'' and also called red date, Chinese date, and Chinese jujube, is a species in the genus '' Ziziphus'' in the buckthorn family Rhamnaceae. Description It is a small deciduous tree or shrub reaching a height of , usually with thorny branches. The leaves are shiny-green, ovate-acute, long and wide, with three conspicuous veins at the base, and a finely toothed margin. The flowers are small, wide, with five inconspicuous yellowish-green petals. The fruit is an edible oval drupe deep; when immature it is smooth-green, with the consistency and taste of an apple with lower acidity, maturing brown to purplish-black, and eventually wrinkled, looking like a small date. There is a single hard kernel, similar to an olive pit, containing two seeds. Chemistry Leaves contain saponin and ziziphin, which suppresses the ability to perceive sweet taste. Flavinoids found in the fruits include Kaempfero ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butana Group
The Butana Group was a prehistoric, neolithic culture in the eastern part of modern Sudan, that flourished from the fourth to the early third millennium BC. The Butana Group is mainly known from its pottery that is often decorated with incised lines, including fingerprints. The ceramic is comparable to those from other (late) neolithic culture in the Sudanese Nile Valley. They produced stone tools. The main economical base was most likely animal breeding, but there is also evidence for domesticated forms of wheat and barley, attesting agriculture. Several animals were hunted such as antelopes, suidae and elephants. Shell middens indicate the extensive use of land snails for food. Not much is known about settlement patterns, but some settlement sites are almost 10 ha large indicating longer occupations. The people of the Butana Group lived in small, round huts. Not many cemeteries are known, but people were most often buried in a contracted position. The only grave goods are pers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atbara River
The Atbarah River ( ar, نهر عطبرة; transliterated: Nahr 'Atbarah), also known as the Black Nile, is a river in northeast Africa. It rises in northwest Ethiopia, approximately 50 km north of Lake Tana and 30 km west of Gondar. It then flows about 805 km (500 mi) to the Nile in north-central Sudan, joining it at the city of Atbarah (). The river's tributary, the Tekezé (Setit) River, is perhaps the true upper course of the Atbarah, as the Tekezé follows the longer course prior to the confluence of the two rivers (at 14° 10' N, 36° E) in northeastern Sudan. The Atbarah is the last tributary of the Nile before it reaches the Mediterranean. For much of the year, it is little more than a stream. However, during the rainy season (generally June to October), the Atbarah rises some 18 ft (5 m) above its normal level. At this time it forms a formidable barrier between the northern and central districts of the Amhara Region of Ethiopia. Beside ...

Sorghum Bicolor
''Sorghum bicolor'', commonly called sorghum () and also known as great millet, broomcorn, guinea corn, durra, imphee, jowar, or milo, is a grass species cultivated for its grain, which is used for food for humans, animal feed, and ethanol production. Sorghum originated in Africa, and is now cultivated widely in tropical and subtropical regions. Sorghum is the world's fifth-most important cereal crop after rice, wheat, maize, and barley, with 59.34 million metric tons of annual global production in 2018. ''S. bicolor'' is typically an annual, but some cultivars are perennial. It grows in clumps that may reach over 4 m high. The grain is small, ranging from 2 to 4 mm in diameter. Sweet sorghums are sorghum cultivars that are primarily grown for forage, syrup production, and ethanol; they are taller than those grown for grain. ''Sorghum bicolor'' is the cultivated species of sorghum; its wild relatives make up the botanical genus ''Sorghum''. History The first archaeological ...

Sorghum
''Sorghum'' () is a genus of about 25 species of flowering plants in the grass family ( Poaceae). Some of these species are grown as cereals for human consumption and some in pastures for animals. One species is grown for grain, while many others are used as fodder plants, either cultivated in warm climates worldwide or naturalized in pasture lands. Taxonomy ''Sorghum'' is in the Poaceae (grass) subfamily Panicoideae and the tribe Andropogoneae (the same as maize, big bluestem and sugarcane). Species Accepted species recorded include: Distribution and habitat Seventeen of the 25 species are native to Australia, with the range of some extending to Africa, Asia, Mesoamerica, and certain islands in the Indian and Pacific Oceans. Toxicity In the early stages of the plants' growth, some species of sorghum can contain levels of hydrogen cyanide, hordenine, and nitrates, which are lethal to grazing animals. Plants stressed by drought or heat can also contain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
