Municipalities Of Brazil
The municipalities of Brazil () are administrative divisions of the states of Brazil, Brazilian states. Brazil currently has 5,571 municipalities, which, given the 2019 population estimate of 210,147,125, makes an average municipality population of 37,728 inhabitants. The average state in Brazil has 214 municipalities. Roraima is the least subdivided state, with 15 municipalities, while Minas Gerais is the most, with 853. Northern states are divided into small numbers of large municipalities (e.g. Amazonas (Brazilian state), Amazonas is divided into only 62 municipalities), and therefore they cover large areas incorporating several separated towns or villages that do not necessarily conform to one single conurbation. Southern and eastern states on the other hand, are divided into many small municipalities (e.g. Minas Gerais), and therefore large urban areas usually extend over several municipalities which form one single conurbation. The Federal District (Brazil), Federal Distr ...

Drywall
Drywall (also called plasterboard, dry lining, wallboard, sheet rock, gib board, gypsum board, buster board, turtles board, slap board, custard board, gypsum panel and gyprock) is a panel made of calcium sulfate dihydrate (gypsum), with or without additives, typically extruded between thick sheets of facer and backer paper, used in the construction of interior walls and ceilings. The plaster is mixed with fiber (typically paper, glass wool, or a combination of these materials); plasticizer, foaming agent; and additives that can reduce mildew, flammability, and water absorption. In the mid-20th century, drywall construction became prevalent in North America as a time- and labor-saving alternative to lath and plaster. History Sackett Board was invented in 1890 by New York Coal Tar Chemical Company employees Augustine Sackett and Fred L. Kane, graduates of Rensselaer Polytechnic Institute. It was made by layering plaster within four plies of wool felt paper. Sheets were thick w ...

Plaster Of Paris
Plaster is a building material used for the protective or decorative coating of walls and ceilings and for moulding and casting decorative elements. In English, "plaster" usually means a material used for the interiors of buildings, while "render" commonly refers to external applications. The term stucco refers to plasterwork that is worked in some way to produce relief decoration, rather than flat surfaces. The most common types of plaster mainly contain either gypsum, lime, or cement,Franz Wirsching "Calcium Sulfate" in Ullmann's Encyclopedia of Industrial Chemistry, 2012 Wiley-VCH, Weinheim. but all work in a similar way. The plaster is manufactured as a dry powder and is mixed with water to form a stiff but workable paste immediately before it is applied to the surface. The reaction with water liberates heat through crystallization and the hydrated plaster then hardens. Plaster can be relatively easily worked with metal tools and sandpaper and can be moulded, either ...

The area codes are distributed geographically, citing the main cities in each area. Local phone numbers in Brazil observe an eight-digit pattern (''dddd-dddd'') for landlines and nine digits (''dddd-ddddd'') for mobile phones. Mobile numbers share the same geographic area codes as landlines, but the first digit differentiates them. Landline numbers start with digits ''2'' through ''5''. Initial digits ''6'' through ''9'' are reserved for mobile numbers, but as of 2017 all mobile numbers in Brazil start with the digit ''9''. (There is an exception for some iDEN mobile lines operated by Nextel, which are eight digits long and start with ''7'' and disestablished in 2018.) Area codes have two digits, and are often notated between parentheses: ''(aa) nnnn-nnnn''. For long-distance calls within Brazil, a z ...

List Of Postal Codes In Brazil
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole". Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of '' The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help ...

Human Development Index
The Human Development Index (HDI) is a statistical composite index of life expectancy, Education Index, education (mean years of schooling completed and expected years of schooling upon entering the education system), and per capita income indicators, which is used to rank countries into four tiers of Human development (humanity), human development. A country scores a higher level of HDI when the life expectancy at birth, lifespan is higher, the education level is higher, and the gross national income GNI (PPP) per capita is higher. It was developed by Pakistani economist Mahbub ul-Haq and was further used to measure a country's development by the United Nations Development Programme (UNDP)'s Human Development Report Office. The 2010 Human Development Report introduced an List of countries by inequality-adjusted Human Development Index, inequality-adjusted Human Development Index (IHDI). While the simple HDI remains useful, it stated that "the IHDI is the actual level of huma ...

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.
