Cidade da Maia is a civil parish in the municipality of Maia, Portugal. It was formed in 2013 by the merger of the former parishes Gueifães, Maia and Vermoim. The population in 2011 was 40,134, in an area of 10.42 km². The parish covers the central area of Maia. In 1902, Maia achieved the status of vila (town). Maia was granted city status (cidade) on 23 August 1986.
Maia is the hometown of two important sports organizations: the football club FC Maia, and the cycling team União Ciclista da Maia.
Maia is a civil parish in the municipality of Ribeira Grande in the Portuguese archipelago of the Azores. The population in 2011 was 1,900, in an area of 21.97 km². Maia is the largest parish by area in Ribeira Grande.
The first Azorean historians referred to this parish, owing to the settlement of Inês da Maia, a noblewoman that established a home here in the 15th Century.
The settlement of the community dates back to the early settlement of Ribeira Grande; the construction of the main church was begun at the end of the 15th Century. By 1522, it had its third vicar. Maia became one of the northern coasts more rapidly growing places: one hundred years after its foundation it had become a civil parish. Its fertile terrains, one of the more productive on the island of São Miguel, and its port access, meant that small industry developed easily in this area. In particular, the tobacco, tea and cement industries developed over the course of the next centuries. Maia was also the location and headquarters for one of the first passenger transport companies on the island.
The candela (/kænˈdɛlə/ or /kænˈdiːlə/; symbol: cd) is the SI base unit of luminous intensity; that is, luminous power per unit solid angle emitted by a point light source in a particular direction. Luminous intensity is analogous to radiant intensity, but instead of simply adding up the contributions of every wavelength of light in the source's spectrum, the contribution of each wavelength is weighted by the standard luminosity function (a model of the sensitivity of the human eye to different wavelengths). A common candle emits light with a luminous intensity of roughly one candela. If emission in some directions is blocked by an opaque barrier, the emission would still be approximately one candela in the directions that are not obscured.
The word candela means candle in Latin.
Like most other SI base units, the candela has an operational definition—it is defined by a description of a physical process that will produce one candela of luminous intensity. Since the 16th General Conference on Weights and Measures (CGPM) in 1979, the candela has been defined as:
Candela is a town and comune in the province of Foggia in the Apulia region of southeast Italy.
The candela is a unit of luminous intensity.
