Rotbav Archaeological Site
Rotbav “La Pârâuț” is a Bronze Age site in southeastern Transylvania, Romania, located at the southern border of the modern village of Rotbav, in Feldioara Commune, and 20 km north of Braşov, capital of the county by the same name. The settlement of Rotbav is situated upon a high terrace formation above the Olt River. Its importance lies in a long stratigraphy comprising the timespan from the Early Bronze Age to the Bronze Age / Iron Age transition. It is the most extensively researched site of this period in the region. History of Research Chance finds from the Bronze Age were made in Rotbav already in the 19th century, but the settlement at “La Pârâuț” was first investigated in the 1950s by a local teacher (Nicolae Croitoru). Systematic archaeological research started in the 1970s with excavations led by Alexandru Vulpe and Mariana Marcu ( Institute of Archaeology Bucharest anMuseum of Braşov and continued since 2005 by Laura Dietrich, Oliver Dietrich and ...

Bronze Age
The Bronze Age is a historic period, lasting approximately from 3300 BC to 1200 BC, characterized by the use of bronze, the presence of writing in some areas, and other early features of urban civilization. The Bronze Age is the second principal period of the three-age system proposed in 1836 by Christian Jürgensen Thomsen for classifying and studying ancient societies and history. An ancient civilization is deemed to be part of the Bronze Age because it either produced bronze by smelting its own copper and alloying it with tin, arsenic, or other metals, or traded other items for bronze from production areas elsewhere. Bronze is harder and more durable than the other metals available at the time, allowing Bronze Age civilizations to gain a technological advantage. While terrestrial iron is naturally abundant, the higher temperature required for smelting, , in addition to the greater difficulty of working with the metal, placed it out of reach of common use until the end o ...

Eastern Mediterranean
Eastern Mediterranean is a loose definition of the eastern approximate half, or third, of the Mediterranean Sea, often defined as the countries around the Levantine Sea. It typically embraces all of that sea's coastal zones, referring to communities connected with the sea and land greatly climatically influenced. It includes the southern half of Turkey's main region Anatolia, its smaller Hatay Province, the island of Cyprus, the Greek Dodecanese islands, and the countries of Egypt, Israel, Jordan, Palestine, Syria and Lebanon. Its broadest uses can embrace the Libyan Sea thus Libya; the Aegean Sea thus European Turkey (East Thrace), the mainland and islands of Greece; and a central part of the Mediterranean, the Ionian Sea, thus southern Albania in Southeast Europe reaching, west, to Italy's farthest south-eastern coasts. Jordan is climatically, and economically part of the region. Regions The eastern Mediterranean region is commonly interpreted in two ways: *The Levant, inc ...

Noua Culture
The Prehistory of Transylvania describes what can be learned about the region known as Transylvania through archaeology, anthropology, comparative linguistics and other allied sciences. Transylvania proper is a plateau or tableland in northwest central Romania. It is bounded and defined by the Carpathian Mountains to the east and south, and the Apuseni Mountains to the west. As a diverse and relatively protected region, the area has always been rich in wildlife, and remains one of the more ecologically diverse areas in Europe. The mountains contain a large number of caves, which attracted both human and animal residents. The Peștera Urșilor, the "Bears Cave", was home to a large number of cave bears (''Ursus spelæus'') whose remains were discovered when the cave was discovered in 1975. Other caves in the area sheltered early humans. Prehistory is the longest period in the history of mankind, throughout of which writing was still unknown. In Transylvania specifically this a ...

Wietenberg Culture
The Wietenberg culture was a Middle Bronze Age archeological culture in Central Transylvania that roughly dates to 2200–1600/1500 BCE. Represented a local variant of Usatove culture, was contemporary with the Ottomány culture and Unetice culture and was replaced by Noua culture. Its name was coined after the eponymic ''Wietenberg Hill'' near Sighișoara. People of this culture traded with the Mycenaeans. Burial sites contain bronze battle axes and maces with stone heads. Pottery consists of amphorae with spiral and meandric ornament. By 1964, about 200 settlements of this culture were discovered.

Stratigraphic
Stratigraphy is a branch of geology concerned with the study of rock layers (strata) and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks. Stratigraphy has three related subfields: lithostratigraphy (lithologic stratigraphy), biostratigraphy (biologic stratigraphy), and chronostratigraphy (stratigraphy by age). Historical development Catholic priest Nicholas Steno established the theoretical basis for stratigraphy when he introduced the law of superposition, the principle of original horizontality and the principle of lateral continuity in a 1669 work on the fossilization of organic remains in layers of sediment. The first practical large-scale application of stratigraphy was by William Smith in the 1790s and early 19th century. Known as the "Father of English geology", Smith recognized the significance of strata or rock layering and the importance of fossil markers for correlating strata; he created the first geologic map o ...

Anno Domini
The terms (AD) and before Christ (BC) are used to label or number years in the Julian and Gregorian calendars. The term is Medieval Latin and means 'in the year of the Lord', but is often presented using "our Lord" instead of "the Lord", taken from the full original phrase "''anno Domini nostri Jesu Christi''", which translates to 'in the year of our Lord Jesus Christ'. The form "BC" is specific to English and equivalent abbreviations are used in other languages: the Latin form is but is rarely seen. This calendar era is based on the traditionally reckoned year of the conception or birth of Jesus, ''AD'' counting years from the start of this epoch and ''BC'' denoting years before the start of the era. There is no year zero in this scheme; thus ''the year AD 1 immediately follows the year 1 BC''. This dating system was devised in 525 by Dionysius Exiguus, but was not widely used until the 9th century. Traditionally, English follows Latin usage by placing the "AD" abbr ...

Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calibration
In measurement technology and metrology, calibration is the comparison of measurement values delivered by a device under test with those of a calibration standard of known accuracy. Such a standard could be another measurement device of known accuracy, a device generating the quantity to be measured such as a voltage, a sound tone, or a physical artifact, such as a meter ruler. The outcome of the comparison can result in one of the following: * no significant error being noted on the device under test * a significant error being noted but no adjustment made * an adjustment made to correct the error to an acceptable level Strictly speaking, the term "calibration" means just the act of comparison and does not include any subsequent adjustment. The calibration standard is normally traceable to a national or international standard held by a metrology body. BIPM Definition The formal definition of calibration by the International Bureau of Weights and Measures (BIPM) is the fo ...

Radiocarbon 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 used to calc ...
