Dikhil Region
The Dikhil Region ( ar, إقليم دخيل, so, Gobolka Dikhil, aa, Rakaakay Dikhil) is a region in southern Djibouti. It is bordered by the Regions of Tadjoura to the north, Arta to the northeast, Ali Sabieh to the east. To the west and south, it has a long line with the Djibouti-Ethiopia border adjacent to the Ethiopia Regions of Afar Region and Somali Region. Dikhil Region is the largest Region in Djibouti by area, with a mainland area of 7,200 square kilometres (2,800 sq mi), it is about the same size as Sikkim. The Dikhil Region's capital is the town of Dikhil. History During the Middle Ages, the Dikhil Region was ruled by the Ifat Sultanate and the Adal Sultanate. It later formed a part of the French Somaliland protectorate in the first half of the 20th century. While the region is built in "administrative position Gobad Dikkil" from March 25, 1927, it is only December 21, 1927 a detachment from Djibouti to recognize the region "and Dekkel Gobad" led by the Arthur Dide ...

Djibouti
Djibouti, ar, جيبوتي ', french: link=no, Djibouti, so, Jabuuti officially the Republic of Djibouti, is a country in the Horn of Africa, bordered by Somalia to the south, Ethiopia to the southwest, Eritrea in the north, and the Red Sea and the Gulf of Aden to the east. The country has an area of . In antiquity, the territory, together with Ethiopia, Eritrea and Somaliland, was part of the Land of Punt. Nearby Zeila, now in Somaliland, was the seat of the medieval Adal and Ifat Sultanates. In the late 19th century, the colony of French Somaliland was established following treaties signed by the ruling Dir Somali sultans with the French, and its railroad to Dire Dawa (and later Addis Ababa) allowed it to quickly supersede Zeila as the port for southern Ethiopia and the Ogaden. It was renamed the French Territory of the Afars and the Issas in 1967. A decade later, the Djiboutian people voted for independence. This officially marked the establishment of the ''Rep ...

Regions Of Djibouti
The regions of Djibouti are the primary geographical divisions through which Djibouti is administered. History The first administrative division of the territory, in 1914, defined two zones besides the city of Djibouti: the districts "Dankali" and "Issa". With the occupation of the territory at the end of the 1920s, the circles of Tadjoura and " Gobad-Dikkil" are created. In 1939, the circle of Ali Sabieh Ali Sabieh ( so, Cali Sabiix, ar, علي صبيح) is the second largest city in Djibouti. It is situated about Southwest of Djibouti City and north of the border with Ethiopia. It sprawls on a wide basin surrounded by granitic mountains on all ... is extracted from the last. In 1963, Obock's circle was created by division of that of Tadjourah region. In 1967, the circle of Djibouti is transformed into district, then divided into three districts. After independence in 1977, the circles become regions. The last important modification of the administrative map of the territor ...

Rhyolite
Rhyolite ( ) is the most silica-rich of volcanic rocks. It is generally glassy or fine-grained (aphanitic) in texture, but may be porphyritic, containing larger mineral crystals (phenocrysts) in an otherwise fine-grained groundmass. The mineral assemblage is predominantly quartz, sanidine, and plagioclase. It is the extrusive equivalent to granite. Rhyolitic magma is extremely viscous, due to its high silica content. This favors explosive eruptions over effusive eruptions, so this type of magma is more often erupted as pyroclastic rock than as lava flows. Rhyolitic ash-flow tuffs are among the most voluminous of continental igneous rock formations. Rhyolitic tuff has been extensively used for construction. Obsidian, which is rhyolitic volcanic glass, has been used for tools from prehistoric times to the present day because it can be shaped to an extremely sharp edge. Rhyolitic pumice finds use as an abrasive, in concrete, and as a soil amendment. Description Rhyolite i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microlith
A microlith is a small Rock (geology), 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 technology, microblade) or a larger blade-like piece of flint by abrupt or truncated retouch (lithics), 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 ...

Blade
A blade is the portion of a tool, weapon, or machine with an edge that is designed to puncture, chop, slice or scrape surfaces or materials. Blades are typically made from materials that are harder than those they are to be used on. Historically, humans have made blades from flaking stones such as flint or obsidian, and from various metal such as copper, bronze and iron. Modern blades are often made of steel or ceramic. Blades are one of humanity's oldest tools, and continue to be used for combat, food preparation, and other purposes. Blades work by concentrating force on the cutting edge. Certain blades, such as those used on bread knives or saws, are serrated, further concentrating force on the point of each tooth. Uses During food preparation, knives are mainly used for slicing, chopping, and piercing. In combat, a blade may be used to slash or puncture, and may also be thrown or otherwise propelled. The function is to sever a nerve, muscle or tendon fibers, or bloo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drill
A drill is a tool used for making round holes or driving fasteners. It is fitted with a bit, either a drill or driverchuck. Hand-operated types are dramatically decreasing in popularity and cordless battery-powered ones proliferating due to increased efficiency and ease of use. Drills are commonly used in woodworking, metalworking, construction, machine tool fabrication, construction and utility projects. Specially designed versions are made for miniature applications. History Around 35,000 BC, ''Homo sapiens'' discovered the benefits of the application of rotary tools. This would have rudimentarily consisted of a pointed rock being spun between the hands to bore a hole through another material. This led to the hand drill, a smooth stick, that was sometimes attached to flint point, and was rubbed between the palms. This was used by many ancient civilizations around the world including the Mayans. The earliest perforated artifacts, such as bone, ivory, shells, and antler ...

List Of Sovereign States
The following is a list providing an overview of sovereign states around the world with information on their status and recognition of their sovereignty. The 206 listed states can be divided into three categories based on membership within the United Nations System: 193 UN member states, 2 UN General Assembly non-member observer states, and 11 other states. The ''sovereignty dispute'' column indicates states having undisputed sovereignty (188 states, of which there are 187 UN member states and 1 UN General Assembly non-member observer state), states having disputed sovereignty (16 states, of which there are 6 UN member states, 1 UN General Assembly non-member observer state, and 9 de facto states), and states having a special political status (2 states, both in free association with New Zealand). Compiling a list such as this can be a complicated and controversial process, as there is no definition that is binding on all the members of the community of nations concerni ...

Obsidian
Obsidian () is a naturally occurring volcanic glass formed when lava extrusive rock, extruded from a volcano cools rapidly with minimal crystal growth. It is an igneous rock. Obsidian is produced from felsic lava, rich in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium. It is commonly found within the margins of rhyolite, rhyolitic lava flows known as obsidian flows. These flows have a high content of silicon dioxide, silica, granting them a high viscosity. The high viscosity inhibits atomic diffusion, diffusion of atoms through the lava, which inhibits the first step (nucleation) in the formation of mineral crystals. Together with rapid cooling, this results in a natural glass forming from the lava. Obsidian is hard, Brittleness, brittle, and amorphous; it therefore Fracture (mineralogy)#Conchoidal fracture, fractures with sharp edges. In the past, it was used to manufacture cutting and piercing tools, and it has been used experimentally as surgic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Well
A well is an excavation or structure created in the ground by digging, driving, or drilling to access liquid resources, usually water. The oldest and most common kind of well is a water well, to access groundwater in underground aquifers. The well water is drawn up by a pump, or using containers, such as buckets or large water bags that are raised mechanically or by hand. Water can also be injected back into the aquifer through the well. Wells were first constructed at least eight thousand years ago and historically vary in construction from a simple scoop in the sediment of a dry watercourse to the qanats of Iran, and the stepwells and sakiehs of India. Placing a lining in the well shaft helps create stability, and linings of wood or wickerwork date back at least as far as the Iron Age. Wells have traditionally been sunk by hand digging, as is still the case in rural areas of the developing world. These wells are inexpensive and low-tech as they use mostly manual labour, an ...
