Road
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", whic ...

Absolute Risk Reduction
The risk difference (RD), excess risk, or attributable risk is the difference between the risk of an outcome in the exposed group and the unexposed group. It is computed as I_e - I_u, where I_eis the incidence in the exposed group, and I_u is the incidence in the unexposed group. If the risk of an outcome is increased by the exposure, the term absolute risk increase (ARI) is used, and computed as I_e - I_u. Equivalently, if the risk of an outcome is decreased by the exposure, the term absolute risk reduction (ARR) is used, and computed as I_u - I_e. The inverse of the absolute risk reduction is the number needed to treat, and the inverse of the absolute risk increase is the number needed to harm. Usage in reporting It is recommended to use absolute measurements, such as risk difference, alongside the relative measurements, when presenting the results of randomized controlled trials. Their utility can be illustrated by the following example of a hypothetical drug which reduces the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rural Delivery Service
Rural delivery service refers to services for the delivery of mail to rural areas. In many countries, rural mail delivery follows different rules and practices from that in urban areas. For example, in some areas rural delivery may require homeowners to travel to a centralized mail delivery depot or a community mailbox rather than being directly served by a door-to-door mail carrier; and even if direct door-to-door delivery is offered, houses still may even not have their own unique mailing addresses at all, but an entire road instead may be assigned a single common address, such as a rural route number. Examples include Rural Free Delivery in the United States, the rural route system in Canada, and the Rural Mail Box addressing system in Australia. Because of the differences in the handling and delivery of mail in rural areas, rural letter carriers often follow different regulatory standards than urban postal workers; for example, rural postal delivery workers may not be require ...

Anglicanism
Anglicanism is a Western Christian tradition that has developed from the practices, liturgy, and identity of the Church of England following the English Reformation, in the context of the Protestant Reformation in Europe. It is one of the largest branches of Christianity, with around 110 million adherents worldwide . Adherents of Anglicanism are called ''Anglicans''; they are also called ''Episcopalians'' in some countries. The majority of Anglicans are members of national or regional ecclesiastical provinces of the international Anglican Communion, which forms the third-largest Christian communion in the world, after the Roman Catholic Church and the Eastern Orthodox Church. These provinces are in full communion with the See of Canterbury and thus with the Archbishop of Canterbury, whom the communion refers to as its '' primus inter pares'' (Latin, 'first among equals'). The Archbishop calls the decennial Lambeth Conference, chairs the meeting of primates, and is the pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Richmond And Danville Railroad
The Richmond and Danville Railroad (R&D) Company was a railroad that operated independently from 1847 until 1894, first in the U.S. state of Virginia, and later on of track in nine states. Chartered on March 9, 1847, the railroad completed its line between Richmond and Danville in 1856.Interstate Commerce Commission. ''Southern Ry. Co.'', Volume 37, Interstate Commerce Commission Valuation Reports, November 6, 1931, p. 555. Washington: United States Government Printing Office, 1932. . During the American Civil War, the railroad was a vital link between the Confederate capital of Richmond and the rest of the Confederacy. After the Civil War, the railroad grew to become the Richmond and Danville Railroad Company System. Placed in receivership in 1892, the Richmond and Danville Railroad Company was sold in 1894 and conveyed into the new Southern Railway Company (later the Norfolk Southern Railway) in 1896 and 1897.

Domain Of A Function
In mathematics, the domain of a function is the set of inputs accepted by the function. It is sometimes denoted by \operatorname(f) or \operatornamef, where is the function. More precisely, given a function f\colon X\to Y, the domain of is . Note that in modern mathematical language, the domain is part of the definition of a function rather than a property of it. In the special case that and are both subsets of \R, the function can be graphed in the Cartesian coordinate system. In this case, the domain is represented on the -axis of the graph, as the projection of the graph of the function onto the -axis. For a function f\colon X\to Y, the set is called the codomain, and the set of values attained by the function (which is a subset of ) is called its range or image. Any function can be restricted to a subset of its domain. The restriction of f \colon X \to Y to A, where A\subseteq X, is written as \left. f \_A \colon A \to Y. Natural domain If a real function is giv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rutherford (unit)
The rutherford (symbol Rd) is a non-SI unit of radioactive decay. It is defined as the activity of a quantity of radioactive material in which one million nuclei decay per second. It is therefore equivalent to one megabecquerel, and one becquerel equals one microrutherford. One rutherford is equivalent to 2.703 × 10−5 curie. The unit was introduced in 1946. It was named after British/New Zealand physicist and Nobel laureate Lord Ernest Rutherford (Nobel Prize in 1908), who was an early leader in the study of atomic nucleus The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment. After the discovery of the neutron i ... disintegrations. After the becquerel was introduced in 1975 as the SI unit for activity, the rutherford became obsolete, and it is no longer commonly used.
