Yasumiba Ruins
The is an archaeological site with the traces of a Japanese Paleolithic period settlement located in what is now the Ashitaka neighborhood of the city of Numazu, Shizuoka in the Tōkai region of Japan. The site was designated a National Historic Site in 1979. It was the first site from the Japanese Paleolithic period to receive National Historic Site designation. Overview During the Upper Paleolithic period, roughly until 13,000 years ago, the shapes and types of stone tools, such as stone axes, spears, and microlith blades evolved due to rapid changes in the environment, which resulted in changes in the fauna available for hunting. Microliths, thin and razor-shape blades of stone which were used by embedding into shafts of wood or bone, appears towards the end of the Upper Paleolithic. The Yasumiba ruins is one of several sites from this period which have been identified in the gently rolling foothills of Mount Ashitaka. This site is located at an elevation of 280 meters on a 6 ...

Lithic Flake
In archaeology, a lithic flake is a "portion of rock removed from an objective piece by percussion or pressure,"Andrefsky, W. (2005) ''Lithics: Macroscopic Approaches to Analysis''. 2d Ed. Cambridge, Cambridge University Press and may also be referred to as simply a ''flake'', or collectively as debitage. The objective piece, or the rock being reduced by the removal of flakes, is known as a core.Andrefsky, W. (2005) ''Lithics: Macroscopic Approaches to Analysis''. 2d Ed. Cambridge, Cambridge University Press Once the proper tool stone has been selected, a percussor or pressure flaker (e.g., an antler tine) is used to direct a sharp blow, or apply sufficient force, respectively, to the surface of the stone, often on the edge of the piece. The energy of this blow propagates through the material, often ( but not always) producing a Hertzian cone of force which causes the rock to fracture in a controllable fashion. Since cores are often struck on an edge with a suitable angle (<90� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tōmei Expressway
The is a national expressway on the island of Honshū in Japan. It is operated by Central Nippon Expressway Company. The expressway is designated as E1 under the "2016 Proposal for Realization of Expressway Numbering", because it parallels National Route 1. It is a part of the Asian Highway Network. Naming The word Tōmei is an acronym consisting of two kanji characters. The first character refers to and the second refers to , which are the two major urban areas linked by the expressway. Officially the expressway is designated as the First Tōkai Expressway. A second Tōkai Expressway (operating as the Shin-Tōmei Expressway) is under construction parallel to the existing route, and is intended to alleviate congestion problems in the near term. The expressway is also a part of Route AH1 of the Asian Highway Network. Overview The Tōmei Expressway is an important roadway linking Tokyo and Nagoya.

Carbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be use ...

Pit Dwelling
A pit-house (or ''pit house'', ''pithouse'') is a house built in the ground and used for shelter. Besides providing shelter from the most extreme of weather conditions, these structures may also be used to store food (just like a pantry, a larder, or a root cellar) and for cultural activities like the telling of stories, dancing, singing and celebrations. General dictionaries also describe a pit-house as a ''dugout'', and it has similarities to a ''half-dugout''. In archaeology, a pit-house is frequently called a ''sunken-featured building'' and occasionally (grub-)hut or ''grubhouse'', after the German name ''Grubenhaus'' They are found in numerous cultures around the world, including the people of the Southwestern United States, the ancestral Pueblo, the ancient Fremont and Mogollon cultures, the Cherokee, the Inuit, the people of the Plateau, and archaic residents of Wyoming (Smith 2003) in North America; Archaic residents of the Lake Titicaca Basin (Craig 2005) in South A ...

Obsidian
Obsidian () is a naturally occurring volcanic glass formed when lava 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 rhyolitic lava flows known as obsidian flows. These flows have a high content of silica, granting them a high viscosity. The high viscosity inhibits 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, brittle, and amorphous; it therefore fractures with sharp edges. In the past, it was used to manufacture cutting and piercing tools, and it has been used experimentally as surgical scalpel blades.
