African Architecture
Like other aspects of the culture of Africa, the architecture of Africa is exceptionally diverse. Throughout the history of Africa, African people, Africans have developed their own local architecture, architectural traditions. In some cases, broader regional styles can be identified, such as the Sudano-Sahelian architecture of West Africa. A common theme in traditional African architecture is the use of fractal scaling: small parts of the structure tend to look similar to larger parts, such as a circular village made of circular houses. African architecture in some areas has been influenced by external cultures for centuries, according to available evidence. Western architecture has influenced coastal areas since the late 15th century and is now an important source of inspiration for many larger buildings, particularly in major cities. African architecture uses a wide range of materials, including thatch, stick/wood, mud, mudbrick, rammed earth, and stone. These material prefere ...

Hunting
Hunting is the Human activity, human practice of seeking, pursuing, capturing, and killing wildlife or feral animals. The most common reasons for humans to hunt are to obtain the animal's body for meat and useful animal products (fur/hide (skin), hide, bone/tusks, horn (anatomy), horn/antler, etc.), for recreation/taxidermy (see trophy hunting), although it may also be done for resourceful reasons such as removing predators dangerous to humans or domestic animals (e.g. wolf hunting), to pest control, eliminate pest (organism), pests and nuisance animals that damage crops/livestock/poultry or zoonosis, spread diseases (see varmint hunting, varminting), for trade/tourism (see safari), or for conservation biology, ecological conservation against overpopulation and invasive species (commonly called a culling#Wildlife, cull). Recreationally hunted species are generally referred to as the ''game (food), game'', and are usually mammals and birds. A person participating in a hunt is a ...

Huts
A hut is a small dwelling, which may be constructed of various local materials. Huts are a type of vernacular architecture because they are built of readily available materials such as wood, snow, stone, grass, palm leaves, branches, clay, hides, fabric, or mud using techniques passed down through the generations. The construction of a hut is generally less complex than that of a house (durable, well-built dwelling) but more so than that of a shelter (place of refuge or safety) such as a tent and is used as temporary or seasonal shelter or as a permanent dwelling in some indigenous societies.Oxford English Dictionary Second Edition on CD-ROM (v. 4.0) © Oxford University Press 2009 Huts exist in practically all nomadic cultures. Some huts are transportable and can stand most conditions of weather. Word The term is often employed by people who consider non-western style homes in tropical and sub-tropical areas to be crude or primitive, but often the designs are based on tra ...

Foundation (engineering)
In engineering, a foundation is the element of a structural engineering, structure which connects it to the ground or more rarely, water (as with Floating building, floating structures), transferring force, loads from the structure to the ground. Foundations are generally considered either Shallow foundation, shallow or Deep foundation, deep. Foundation engineering is the application of soil mechanics and rock mechanics (geotechnical engineering) in the design of foundation elements of structures. Purpose Foundations provide the structure's stability from the ground: * To distribute the weight of the structure over a large area in order to avoid overloading the underlying soil (possibly causing unequal settlement). * To anchor the structure against natural forces including earthquakes, floods, droughts, frost heaves, tornadoes and wind. * To provide a level surface for construction. * To anchor the structure deeply into the ground, increasing its stability and preventing over ...

Epipaleolithic
In archaeology, the Epipalaeolithic or Epipaleolithic (sometimes Epi-paleolithic etc.) is a period occurring between the Upper Paleolithic and Neolithic during the Stone Age. Mesolithic also falls between these two periods, and the two are sometimes confused or used as synonyms. More often, they are distinct, referring to approximately the same period of time in different geographic areas. Epipaleolithic always includes Epipalaeolithic Near East, this period in the Levant and, often, the rest of the Near East. It sometimes includes parts of Southeast Europe, where Mesolithic is much more commonly used. Mesolithic very rarely includes the Levant or the Near East; in Europe, Epipalaeolithic is used, though not very often, to refer to the early Mesolithic. The Epipalaeolithic has been defined as the "final Upper Palaeolithic industries occurring at the end of the final Last glacial period, glaciation which appear to merge technologically into the Mesolithic". The period is general ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Of Africa
The climate of Africa is a range of climates such as the equatorial climate, the tropical wet and dry climate, the tropical monsoon climate, the semi-arid climate (semi-desert and steppe), the desert climate (hyper-arid and arid), the humid subtropical climate, and the subtropical highland climate. Temperate climates are rare across the continent except at very high elevations and along the fringes. In fact, the climate of Africa is more variable by rainfall amount than by temperatures, which are consistently high. African deserts are the sunniest and the driest parts of the continent, owing to the prevailing presence of the subtropical ridge with subsiding, hot, dry air masses. Africa holds many heat-related records: the continent has the hottest extended region year-round, the areas with the hottest summer climate, the highest sunshine duration, and more. Owing to Africa's position across equatorial and subtropical latitudes in both the northern and southern hemisphere, sever ...

Rockshelters
A rock shelter (also rockhouse, crepuscular cave, bluff shelter, or abri) is a shallow cave-like opening at the base of a bluff or cliff. In contrast to solutional caves (karst), which are often many miles long or wide, rock shelters are almost always modest in size and extent. Formation Rock shelters form because a rock stratum such as sandstone that is resistant to erosion and weathering has formed a cliff or bluff, but a softer stratum, more subject to erosion and weathering, lies just below the resistant stratum, and thus undercuts the cliff. In arid areas, wind erosion (Aeolian erosion) can be an important factor in rockhouse formation. In most humid areas, the most important factor in rockhouse formation is frost spalling, where the softer, more porous rock underneath is pushed off, tiny pieces at a time, by frost expansion from water frozen in the pores. Erosion from moving water is seldom a significant factor. Many rock shelters are found under waterfalls. File:R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Pleistocene
The Late Pleistocene is an unofficial Age (geology), age in the international geologic timescale in chronostratigraphy, also known as the Upper Pleistocene from a Stratigraphy, stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between 129,000 and c. 11,700 years ago. The late Pleistocene equates to the proposed Tarantian Age of the geologic time scale, preceded by the officially ratified Chibanian (commonly known as the Middle Pleistocene). The beginning of the Late Pleistocene is the transition between the end of the Penultimate Glacial Period and the beginning of the Last Interglacial around 130,000 years ago (corresponding with the beginning of Marine Isotope Stage 5). The Late Pleistocene ends with the termination of the Younger Dryas, some 10th millennium BC, 11,700 years ago when the Holocene Epoch began. The term Upper Pleistocene is currently in use as a p ...

Before Present
Before Present (BP) or "years before present (YBP)" is a time scale used mainly in archaeology, geology, and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1January 1950 as the commencement date (epoch) of the age scale, with 1950 being labelled as the "standard year". The abbreviation "BP" has been interpreted retrospectively as "Before Physics", which refers to the time before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, which scientists must account for when using radiocarbon dating for dates of origin that may fall after this year. In a convention that is not always observed, many sources restrict the use of BP dates to those produced with radiocarbon dating; the alternative notation "RCYBP" stands for the explicit "radio carbon years before present". Usage The BP scale is s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Facies
In geology, a facies ( , ; same pronunciation and spelling in the plural) is a body of rock with distinctive characteristics. The characteristics can be any observable attribute of rocks (such as their overall appearance, composition, or condition of formation) and the changes that may occur in those attributes over a geographic area. A facies encompasses all the characteristics of a rock including its chemical, physical, and biological features that distinguish it from adjacent rock. The term "facies" was introduced by the Swiss geologist Amanz Gressly in 1838 and was part of his significant contribution to the foundations of modern stratigraphy, which replaced the earlier notions of '' Neptunism''. Walther's law Walther's law of facies, or simply Walther's law, named after the geologist Johannes Walther, states that the vertical succession of facies reflects lateral changes in environment. Conversely, it states that when a depositional environment "migrates" laterally, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kel Essuf Rock Art
Kel Essuf rock art is the earliest form of engraved anthropomorphic Central Saharan rock art, which was produced prior to 9800 BP, at least as early as 12,000 BP amid the late period of the Pleistocene. The Kel Essuf Period is preceded by the Bubaline Period and followed by the Round Head Period. Kel Essuf rock art usually depicts oval-shaped artforms, which possess four short appendages – two upper appendages, or arms, that may have between three and four finger-like digits, and two lower appendages, or legs – as well as an additional appendage, or penile appendage, without finger-like digits, which may be indicative of maleness. Concealed remnants of dismantled furnished flooring are found in 75% of the Central Saharan rockshelters where Kel Essuf rock artforms are found. The furnished flooring in these rockshelters were likely created for the purpose of collecting water and were subsequently dismantled after the earliest Round Head rock art began to be created. The Kel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Round Head Rock Art
Round Head rock art is the earliest Cave painting, painted, monumental form of Central Saharan rock art, which was largely created from 9500 BP to 7500 BP and ceased being created by 3000 BP. The Round Head Period is preceded by the Kel Essuf Period and followed by the Pastoral Period. Round Head rock art number up to several thousand depictions in the Central Sahara. Human and undomesticated animal (e.g., Barbary sheep, antelope) artforms are usually portrayed, with a variety of details (e.g., African dance, dancing, Traditional African religions#Ceremonies, ceremonies, Traditional African masks, masks, spiritual animal forms), in painted Round Head rock art. Painted Round Head rock art and engraved Kel Essuf rock art usually share the same region and occasionally the same rockshelters. The Round Head rock art of Tassili and the surrounding mountainous areas bear considerable similarity with traditional Sub-Saharan Africa#Culture, Sub-Saharan African cultures. At the start of 1 ...
