Huelva (province)
Huelva () is a province of southern Spain, in the western part of the autonomous community of Andalusia. It is bordered by Portugal, the provinces of Badajoz, Seville, and Cádiz, and the Atlantic Ocean. Its capital is Huelva. Its area is 10,148 km². Its population is 483,792 (2005), of whom about 30% live in the capital, and its population density is 47.67/km². It contains 79 municipalities. The economy is based on agriculture and mining. The famous Rio Tinto mines have been worked since before 1000 BC, and were the major source of copper for the Roman Empire. As an indication of the scope of ancient mining, sixteen million tons of Roman slag have been identified at the Roman mines. British companies resumed large-scale mining in 1873; the district is the namesake of the Rio Tinto Group. In the 21st century, municipalities such as Moguer, Palos de la Frontera, and Lepe, have witnessed the development of intensive water-demanding strawberry farming, which has elicite ...

Mayor
In many countries, a mayor is the highest-ranking official in a Municipal corporation, municipal government such as that of a city or a town. Worldwide, there is a wide variance in local laws and customs regarding the powers and responsibilities of a mayor as well as the means by which a mayor is elected or otherwise mandated. Depending on the system chosen, a mayor may be the chief executive officer of the municipal government, may simply chair a multi-member governing body with little or no independent power, or may play a solely ceremonial role. A mayor's duties and responsibilities may be to appoint and oversee municipal managers and employees, provide basic governmental services to constituents, and execute the laws and ordinances passed by a municipal governing body (or mandated by a state, territorial or national governing body). Options for selection of a mayor include direct election by the public, or selection by an elected governing council or board. The term ''mayor ...

Central European Time
Central European Time (CET) is a standard time of Central, and parts of Western Europe, which is one hour ahead of Coordinated Universal Time (UTC). The UTC offset, time offset from UTC can be written as UTC+01:00. It is used in most parts of Europe and in several African countries. CET is also known as Middle European Time (MET, German: :de:Mitteleuropäische Zeit, MEZ) and by colloquial names such as Amsterdam Time, Berlin Time, Brussels Time, Budapest Time, Madrid Time, Paris Time, Stockholm Time, Rome Time, Prague time, Warsaw Time or Romance Standard Time (RST). The 15th meridian east is the central axis per UTC+01:00 in the world system of time zones. As of 2023, all member state of the European Union, member states of the European Union observe summer time (daylight saving time), from the last Sunday in March to the last Sunday in October. States within the CET area switch to Central European Summer Time (CEST, UTC+02:00) for the summer. The next change to CET is scheduled ...

Central European Summer Time
Central European Summer Time (CEST, UTC+02:00), sometimes referred to as Central European Daylight Time (CEDT), is the standard clock time observed during the period of summer daylight-saving in those European countries which observe Central European Time (CET; UTC+01:00) during the other part of the year. It corresponds to UTC+02:00, which makes it the same as Eastern European Time, Central Africa Time, South African Standard Time, Egypt Standard Time and Kaliningrad Time in Russia. Names Other names which have been applied to Central European Summer Time are Middle European Summer Time (MEST), Central European Daylight Saving Time (CEDT), and Bravo Time (after the second letter of the NATO phonetic alphabet). Period of observation Since 1996, European Summer Time has been observed between 01:00 UTC (02:00 CET and 03:00 CEST) on the last Sunday of March, and 01:00 UTC on the last Sunday of October; previously the rules were not uniform across the European Union.

Census
A census (from Latin ''censere'', 'to assess') is the procedure of systematically acquiring, recording, and calculating population information about the members of a given Statistical population, population, usually displayed in the form of statistics. This term is used mostly in connection with Population and housing censuses by country, national population and housing censuses; other common censuses include Census of agriculture, censuses of agriculture, traditional culture, business, supplies, and traffic censuses. The United Nations (UN) defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory, simultaneity and defined periodicity", and recommends that population censuses be taken at least every ten years. UN recommendations also cover census topics to be collected, official definitions, classifications, and other useful information to coordinate international practices.

Ancient Carthage
Ancient Carthage ( ; , ) was an Ancient Semitic-speaking peoples, ancient Semitic civilisation based in North Africa. Initially a settlement in present-day Tunisia, it later became a city-state, and then an empire. Founded by the Phoenicians in the ninth century BC, Carthage reached its height in the fourth century BC as one of the largest ''metropoleis'' in the world.George Modelski, ''World Cities: –3000 to 2000'', Washington DC: FAROS 2000, 2003. . Figures in main tables are preferentially cited. Part of former estimates can be read at Evolutionary World Politics Homepage Archived 2008-12-28 at the Wayback Machine It was the centre of the Carthaginian Empire, a major power led by the Punic people who dominated the ancient western and central Mediterranean Sea. Following the Punic Wars, Carthage was Siege of Carthage (Third Punic War), destroyed by the Romans in 146 BC, who later rebuilt Roman Carthage, the city lavishly.

Skutterudite
Skutterudite is a cobalt arsenide mineral containing variable amounts of nickel and iron substituting for cobalt with the ideal formula CoAs3. Some references give the arsenic a variable formula subscript of 2–3. High nickel varieties are referred to as nickel-skutterudite, previously chloanthite. It is a hydrothermal ore mineral found in moderate to high temperature veins with other Ni-Co minerals. Associated minerals are arsenopyrite, native silver, erythrite, annabergite, nickeline, cobaltite, silver sulfosalts, native bismuth, calcite, siderite, barite and quartz. It is mined as an ore of cobalt and nickel with a by-product of arsenic. The crystal structure of this mineral has been found to be exhibited by several compounds with important technological uses. The mineral has a bright metallic luster, and is tin white or light steel gray in color with a black streak. The specific gravity is 6.5 and the hardness is 5.5–6. Its crystal structure is isometric with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nickeline
Nickeline or niccolite is the mineral form of nickel arsenide. The naturally-occurring mineral contains roughly 43.9% nickel and 56.1% arsenic by mass, but composition of the mineral may vary slightly. Small quantities of sulfur, iron and cobalt are usually present, and sometimes the arsenic is largely replaced by antimony. This last forms an isomorphous series with breithauptite (nickel antimonide). Etymology and history Medieval miners looking for copper in the German Ore Mountains would sometimes find a red mineral, superficially resembling copper ore. Upon attempting extraction, no copper was produced, and subsequently, the miners would be afflicted with mysterious illness. They blamed a mischievous sprite of German mythology, Nickel (similar to ''Old Nick'') for besetting the copper (German: Kupfer). This German equivalent of "copper-nickel" was used as early as 1694 (other old German synonyms are ''Rotnickelkies'' and ''Arsennickel''). In 1751, Baron Axel Fredrik Crons ...
