Callatis
Mangalia (, tr, Mankalya), ancient Callatis ( el, Κάλλατις/Καλλατίς; other historical names: Pangalia, Panglicara, Tomisovara), is a city and a port on the coast of the Black Sea in the south-east of Constanța County, Northern Dobruja, Romania. The municipality of Mangalia also administers several summertime seaside resorts: Cap Aurora, Jupiter, Neptun, Olimp, Saturn, Venus. History The Greek town Callatis existed until the mid-7th century under this name. Life in the town resumed from the 10th century. In the 13th century Callatis came to be known as Pangalia. The Vlachs called it Tomisovara and the Greeks called it Panglicara. From the 16th century the town had acquired its present name, Mangalia. A Greek colony named Callatis was founded in the 6th century BC by the city of Heraclea Pontica. Its first silver coinage was minted around 350 BC. In 72 BC, Callatis was conquered by the Roman general Lucullus and was assigned to the Roman province of Moesia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Dobruja
Northern Dobruja ( ro, Dobrogea de Nord or simply ; bg, Северна Добруджа, ''Severna Dobrudzha'') is the part of Dobruja within the borders of Romania. It lies between the lower Danube river and the Black Sea, bordered in the south by Southern Dobruja, which is part of Bulgaria. History Around 600 BC, the Greeks colonized the Black Sea shore and founded numerous fortresses: Tomis (today's Constanta), Callatis, Histria, Argamum, Heracleea, Aegysus. Greeks have commerce with dacians who lived there on main land. Dobruja became a Roman province after conquest of Dacian Tribes. One of the best preserved remnants of this period is the Capidava citadel. Between the 7th and 14th century, Dobruja was part of the First Bulgarian Empire and the Second Bulgarian Empire. For a long period in the 14-15th century, Dobruja became part of Wallachia. The territory fell under Ottoman rule from the mid-15th century until 1878, when it was awarded to Romania for its role in the ...

Heraclea Pontica
__NOTOC__ Heraclea Pontica (; gr, Ἡράκλεια Ποντική, Hērakleia Pontikē), known in Byzantine and later times as Pontoheraclea ( gr, Ποντοηράκλεια, Pontohērakleia), was an ancient city on the coast of Bithynia in Asia Minor, at the mouth of the river Lycus. It was founded by the Greek city-state of Megara in approximately 560–558 BC and was named after Heracles who the Greeks believed entered the underworld at a cave on the adjoining Archerusian promontory (Cape Baba). The site is now the location of the modern city Karadeniz Ereğli, in the Zonguldak Province of Turkey. The colonists soon subjugated the native Mariandynians but agreed to terms that none of the latter, now helot-like serfs, be sold into slavery outside their homeland. Prospering from the rich, fertile adjacent lands and the sea-fisheries of its natural harbor, Heraclea soon extended its control along the coast as far east as Cytorus (Gideros, near Cide), eventually establishing ...

Municipiu
A municipiu (from Latin ''municipium''; English: municipality) is a level of administrative subdivision in Romania and Moldova, roughly equivalent to city in some English-speaking countries. In Romania, this status is given to towns that are large and urbanized; at present, there are 103 ''municipii''. There is no clear benchmark regarding the status of ''municipiu'' even though it applies to localities which have a sizeable population, usually above 15,000, and extensive urban infrastructure. Localities that do not meet these loose guidelines are classified only as towns ('' orașe''), or if they are not urban areas, as communes (''comune''). Cities are governed by a mayor and local council. There are no official administrative subdivisions of cities even though, unofficially, municipalities may be divided into quarters/districts (''cartiere'' in Romanian). The exception to this is Bucharest, which has a status similar to that of a county, and is officially subdivided into six a ...

First Bulgarian Empire
The First Bulgarian Empire ( cu, блъгарьско цѣсарьствиѥ, blagarysko tsesarystviye; bg, Първо българско царство) was a medieval Bulgar- Slavic and later Bulgarian state that existed in Southeastern Europe between the 7th and 11th centuries AD. It was founded in 680–681 after part of the Bulgars, led by Asparuh, moved south to the northeastern Balkans. There they secured Byzantine recognition of their right to settle south of the Danube by defeatingpossibly with the help of local South Slavic tribesthe Byzantine army led by Constantine IV. During the 9th and 10th century, Bulgaria at the height of its power spread from the Danube Bend to the Black Sea and from the Dnieper River to the Adriatic Sea and became an important power in the region competing with the Byzantine Empire. It became the foremost cultural and spiritual centre of south Slavic Europe throughout most of the Middle Ages. As the state solidified its position in the ...

Organism
In biology, an organism () is any living system that functions as an individual entity. All organisms are composed of cells (cell theory). Organisms are classified by taxonomy into groups such as multicellular animals, plants, and fungi; or unicellular microorganisms such as protists, bacteria, and archaea. All types of organisms are capable of reproduction, growth and development, maintenance, and some degree of response to stimuli. Beetles, squids, tetrapods, mushrooms, and vascular plants are examples of multicellular organisms that differentiate specialized tissues and organs during development. A unicellular organism may be either a prokaryote or a eukaryote. Prokaryotes are represented by two separate domains – bacteria and archaea. Eukaryotic organisms are characterized by the presence of a membrane-bound cell nucleus and contain additional membrane-bound compartments called organelles (such as mitochondria in animals and plants ...

Solar Radiation
Solar irradiance is the power per unit area (surface power density) received from the Sun in the form of electromagnetic radiation in the wavelength range of the measuring instrument. Solar irradiance is measured in watts per square metre (W/m2) in SI units. Solar irradiance is often integrated over a given time period in order to report the radiant energy emitted into the surrounding environment ( joule per square metre, J/m2) during that time period. This integrated solar irradiance is called solar irradiation, solar exposure, solar insolation, or insolation. Irradiance may be measured in space or at the Earth's surface after atmospheric absorption and scattering. Irradiance in space is a function of distance from the Sun, the solar cycle, and cross-cycle changes.Michael Boxwell, ''Solar Electricity Handbook: A Simple, Practical Guide to Solar Energy'' (2012), p. 41–42. Irradiance on the Earth's surface additionally depends on the tilt of the measuring surface, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spring (hydrosphere)
A spring is a point of exit at which groundwater from an aquifer flows out on top of Earth's crust ( pedosphere) and becomes surface water. It is a component of the hydrosphere. Springs have long been important for humans as a source of fresh water, especially in arid regions which have relatively little annual rainfall. Springs are driven out onto the surface by various natural forces, such as gravity and hydrostatic pressure. Their yield varies widely from a volumetric flow rate of nearly zero to more than for the biggest springs. Formation Springs are formed when groundwater flows onto the surface. This typically happens when the groundwater table reaches above the surface level. Springs may also be formed as a result of karst topography, aquifers, or volcanic activity. Springs also have been observed on the ocean floor, spewing hot water directly into the ocean. Springs formed as a result of karst topography create karst springs, in which ground water travels throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Breeze
A sea breeze or onshore breeze is any wind that blows from a large body of water toward or onto a landmass; it develops due to differences in air pressure created by the differing heat capacities of water and dry land. As such, sea breezes are more localised than prevailing winds. Because land heats up much faster than water under solar radiation, a sea breeze is a common occurrence along coasts after sunrise. By contrast, a land breeze or offshore breeze is the reverse effect: dry land also cools more quickly than water and, after sunset, a sea breeze dissipates and the wind instead flows from the land towards the sea. Sea breezes and land breezes are both important factors in coastal regions' prevailing winds. The term offshore wind may refer to any wind over open water. Wind farms are often situated near a coast to take advantage of the normal daily fluctuations of wind speed resulting from sea or land breezes. While many onshore wind farms and offshore wind farms do no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precipitation (meteorology)
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravitational pull from clouds. The main forms of precipitation include drizzle, rain, sleet, snow, ice pellets, graupel and hail. Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor (reaching 100% relative humidity), so that the water condenses and "precipitates" or falls. Thus, fog and mist are not precipitation but colloids, because the water vapor does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated: cooling the air or adding water vapor to the air. Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called showers. Moisture that is lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be conden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Băile Herculane
Băile Herculane ( la, Aqua Herculis; german: Herkulesbad; hu, Herkulesfürdő; cz, Herkulovy Lázně, tr, Lazarethane) is a spa town in Romanian Banat, in Caraș-Severin County, situated in the valley of the Cerna River, between the Mehedinți Mountains to the east and the Cerna Mountains to the west, elevation 168 meters.

Climate
Climate is the long-term weather pattern in an area, typically averaged over 30 years. More rigorously, it is the mean and variability of meteorological variables over a time spanning from months to millions of years. Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation. In a broader sense, climate is the state of the components of the climate system, including the atmosphere, hydrosphere, cryosphere, lithosphere and biosphere and the interactions between them. The climate of a location is affected by its latitude/longitude, terrain, altitude, land use and nearby water bodies and their currents. Climates can be classified according to the average and typical variables, most commonly temperature and precipitation. The most widely used classification scheme was the Köppen climate classification. The Thornthwaite system, in use since 1948, incorporates evapotranspiration along wit ...
