Full Stop
The full stop (Commonwealth English), period (North American English), or full point , is a punctuation mark. It is used for several purposes, most often to mark the end of a declarative sentence (as distinguished from a question or exclamation). This sentence-ending use, alone, defines the strictest sense of ''full stop''. Although ''full stop'' technically applies only when the mark is used to end a sentence, the distinction – drawn since at least 1897 – is not maintained by all modern style guides and dictionaries. The mark is also used, singly, to indicate omitted characters or, in a series, as an ellipsis (), to indicate omitted words. It may be placed after an initial letter used to stand for a name or after each individual letter in an initialism or acronym (e.g., "U.S.A."). However, the use of full stops after letters in an initialism or acronym is declining, and many of these without punctuation have become accepted norms (e.g., "UK" and "NATO"). This trend has pro ...

Period (geology)
The geologic time scale, or geological time scale, (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (scientific branch of geology that aims to determine the age of rocks). It is used primarily by Earth scientists (including geologists, paleontologists, geophysicists, geochemists, and paleoclimatologists) to describe the timing and relationships of events in geologic history. The time scale has been developed through the study of rock layers and the observation of their relationships and identifying features such as lithologies, paleomagnetic properties, and fossils. The definition of standardized international units of geologic time is the responsibility of the International Commission on Stratigraphy (ICS), a constituent body of the International Union of Geological Sciences (IUGS), whose primary objective is to precisely define ...

Periodization
In historiography, periodization is the process or study of categorizing the past into discrete, quantified, and named blocks of time for the purpose of study or analysis.Adam Rabinowitz. It's about time: historical periodization and Linked Ancient World Data'. Institute for the Study of the Ancient World Papers, 2014. This is usually done in order to understand current and historical processes, and the causality that might have linked those events. Periodizations can provide a convenient segmentation of time, wherein events within the period might consist of relatively similar characteristics. However, determining the precise beginning and ending of any ‘period’ is often arbitrary, since it has changed over time and over the course of history. Systems of periodization are more or less arbitrary, yet it provides a framework to help us understand them. Periodizing labels are continually challenged and redefined, but once established, period "brands" are so convenient that many ...

Accounting Period
An accounting period, in bookkeeping, is the period with reference to which management accounts and financial statements are prepared. In management accounting the accounting period varies widely and is determined by management. Monthly accounting periods are common. In financial accounting the accounting period is determined by regulation and is usually 12 months. The beginning of the accounting period differs according to jurisdiction. For example, one entity may follow the calendar year, January to December, while another may follow April to March as the accounting period. The International Financial Reporting Standards allow a period of 52 weeks as an accounting period instead of 12 months. This method is known as the 4-4-5 calendar in British and Commonwealth usage and the 52–53-week fiscal year in the United States. In the United States the method is permitted by generally accepted accounting principles, as well as by US Internal Revenue Code Regulation 1.441-2 (IRS ...

Period (ice Hockey)
Ice hockey (or simply hockey) is a team sport played on ice skates, usually on an ice skating rink with lines and markings specific to the sport. It belongs to a family of sports called hockey. In ice hockey, two opposing teams use ice hockey sticks to control, advance and shoot a closed, vulcanized, rubber disc called a " puck" into the other team's goal. Each goal is worth one point. The team which scores the most goals is declared the winner. In a formal game, each team has six skaters on the ice at a time, barring any penalties, one of whom is the goaltender. Ice hockey is a full contact sport. Ice hockey is one of the sports featured in the Winter Olympics while its premiere international amateur competition, the IIHF World Championships, are governed by the International Ice Hockey Federation (IIHF) for both men's and women's competitions. Ice hockey is also played as a professional sport. In North America as well as many European countries, the sport is known simply ...

Period (school)
A school period is a block of time allocated for lessons/classes in schools and colleges. They typically last between 30 and 120 minutes, with around 3-10 periods per school day. However, especially in higher education, there can be many more. Educators determine the number and length of these periods, and may even regulate how each period will be used. One common example of this practice is to designate at least one compulsory period a day for physical education. A school bell The ringing of a school bell announces important times to a school's students and staff, such as marking the beginnings and ends of the school day, class period, and breaks. In some schools it may take the form of a physical bell, usually e ... is often used to indicate when a period begins and ends.

Sentence (linguistics)
In linguistics and grammar, a sentence is a linguistic expression, such as the English example "The quick brown fox jumps over the lazy dog." In traditional grammar, it is typically defined as a string of words that expresses a complete thought, or as a unit consisting of a subject and predicate. In non-functional linguistics it is typically defined as a maximal unit of syntactic structure such as a constituent. In functional linguistics, it is defined as a unit of written texts delimited by graphological features such as upper-case letters and markers such as periods, question marks, and exclamation marks. This notion contrasts with a curve, which is delimited by phonologic features such as pitch and loudness and markers such as pauses; and with a clause, which is a sequence of words that represents some process going on throughout time. A sentence can include words grouped meaningfully to express a statement, question, exclamation, request, command, or suggestion. Typical a ...

Wavelength
In physics, the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats. It is the distance between consecutive corresponding points of the same phase on the wave, such as two adjacent crests, troughs, or zero crossings, and is a characteristic of both traveling waves and standing waves, as well as other spatial wave patterns. The inverse of the wavelength is called the spatial frequency. Wavelength is commonly designated by the Greek letter ''lambda'' (λ). The term ''wavelength'' is also sometimes applied to modulated waves, and to the sinusoidal envelopes of modulated waves or waves formed by interference of several sinusoids. Assuming a sinusoidal wave moving at a fixed wave speed, wavelength is inversely proportional to frequency of the wave: waves with higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths. Wavelength depends on the medium (for example, vacuum, air, or water) that a wav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
