African American (U
African Americans (also referred to as Black Americans and Afro-Americans) are an ethnic group consisting of Americans with partial or total ancestry from sub-Saharan Africa. The term "African American" generally denotes descendants of enslaved Africans who are from the United States. While some Black immigrants or their children may also come to identify as African-American, the majority of first generation immigrants do not, preferring to identify with their nation of origin. African Americans constitute the second largest racial group in the U.S. after White Americans, as well as the third largest ethnic group after Hispanic and Latino Americans. Most African Americans are descendants of enslaved people within the boundaries of the present United States. On average, African Americans are of West/ Central African with some European descent; some also have Native American and other ancestry.

White (U
White is the lightest color and is achromatic (having no hue). It is the color of objects such as snow, chalk, and milk, and is the opposite of black. White objects fully reflect and scatter all the visible wavelengths of light. White on television and computer screens is created by a mixture of red, blue, and green light. The color white can be given with white pigments, especially titanium dioxide. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore white togas as symbols of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity. It was the royal color of the kings of France, and of the monarchist movement that opposed the Bolsheviks during the Russian Civil War (1917–1922). Greek and Roman temples were faced with white marble, and beginning in the 18th century, with the advent of neoclassical architecture, white became the most common color of new churches ...

Population Density
Population density (in agriculture: standing stock or plant density) is a measurement of population per unit land area. It is mostly applied to humans, but sometimes to other living organisms too. It is a key geographical term.Matt RosenberPopulation Density Geography.about.com. March 2, 2011. Retrieved on December 10, 2011. In simple terms, population density refers to the number of people living in an area per square kilometre, or other unit of land area. Biological population densities Population density is population divided by total land area, sometimes including seas and oceans, as appropriate. Low densities may cause an extinction vortex and further reduce fertility. This is called the Allee effect after the scientist who identified it. Examples of the causes of reduced fertility in low population densities are * Increased problems with locating sexual mates * Increased inbreeding Human densities Population density is the number of people per unit of area, usuall ...

Census
A census is the procedure of systematically acquiring, recording and calculating information about the members of a given population. This term is used mostly in connection with national population and housing censuses; other common censuses include 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 co-ordinate international practices. The UN's Food and Agriculture Organization (FAO), in turn, defines the census of agriculture as "a statistical operation for collecting, processing and disseminating data on the structure of agriculture, covering th ...

National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners and inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Iron Company
The Thomas Iron Company was a major iron-making firm in Hokendauqua, Pennsylvania in the Lehigh Valley region of eastern Pennsylvania from its organization in 1854 until its decline and eventual dismantling in the early 20th century. The firm was named in honor of its founder, David Thomas, who had emigrated to the United States in 1839 to introduce hot blast iron making in the Lehigh Valley, and now embarked on an independent ironmaking venture. Thomas Iron Company's main and original plant was in Hokendauqua, Pennsylvania, which grew up around it. The company also came to own blast furnaces and railroads elsewhere in the Lehigh Valley and mines in both Pennsylvania and New Jersey. Changes in the iron industry in the early Twentieth Century left Thomas Iron struggling to compete, and after a failed attempt at modernization and revival from 1913 to 1916, the company's assets were sold and largely dismantled during the 1920s. Origins David Thomas, a Welsh ironmaster, had been br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lock Ridge Park
Lock Ridge Park is a park built around a historic iron ore blast furnace just outside Alburtis, Pennsylvania in the Lehigh Valley region of eastern Pennsylvania. History The park preserves portions of the former Lock Ridge Iron Works. The first furnace at the site was built in 1868 by the Lock Ridge Iron Company, on the line of the Catasauqua and Fogelsville Railroad near its junction with the East Pennsylvania Railroad. The company was taken over the next year by the Thomas Iron Company, and a second furnace put in blast shortly thereafter. The iron industry in the Lehigh Valley was then flourishing, and the Lock Ridge furnaces (designated No. 7 and No. 8 by Thomas Iron) were typical of the time. They used a hot blast to burn anthracite fuel (rather than the hitherto common charcoal) a technology brought to the United States by the company's founder, David Thomas, in 1839. However, by the early 20th century, the furnaces were, despite sporadic improvements, technologically out- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reading Company
The Reading Company ( ) was a Philadelphia-headquartered railroad that provided passenger and commercial rail transport in eastern Pennsylvania and neighboring states that operated from 1924 until its 1976 acquisition by Conrail. Commonly called the Reading Railroad, and logotyped as Reading Lines, the Reading Company was a railroad holding company for the majority of its existence and was a single railroad during its later years. It operated service as Reading Railway System and was a successor to the Philadelphia and Reading Railway Company, founded in 1833. Until the decline in anthracite loadings in the Coal Region after World War II, it was one of the most prosperous corporations in the United States. Competition with the modern trucking industry that used the interstate highway system for short-distance transportation of goods, also known as short hauls, compounded the company's problems, forcing it into bankruptcy in 1971. Its railroad operations were merged into Conrail i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hardiness Zone
A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a rough guide for landscaping and gardening, defines 13 zones by long-term average annual extreme minimum temperatures. It has been adapted by and to other countries (such as Canada) in various forms. Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale. For example, a plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 °F (−1.1 °C) to 40 °F (4.4 °C). Other hardiness rating schemes have been developed as well, such as the UK Royal Horticultural Society and US Sunset Western Garden Book systems. A heat zone (s ...

Humid Continental Climate
A humid continental climate is a climatic region defined by Russo-German climatologist Wladimir Köppen in 1900, typified by four distinct seasons and large seasonal temperature differences, with warm to hot (and often humid) summers and freezing cold (sometimes severely cold in the northern areas) winters. Precipitation is usually distributed throughout the year but often do have dry seasons. The definition of this climate regarding temperature is as follows: the mean temperature of the coldest month must be below or depending on the isotherm, and there must be at least four months whose mean temperatures are at or above . In addition, the location in question must not be semi-arid or arid. The cooler ''Dfb'', ''Dwb'', and ''Dsb'' subtypes are also known as hemiboreal climates. Humid continental climates are generally found between latitudes 30° N and 60° N, within the central and northeastern portions of North America, Europe, and Asia. They are rare and isolat ...
