Policies And Guidelines
Policy is a deliberate system of guidelines to guide decisions and achieve rational outcomes. A policy is a statement of intent and is implemented as a procedure or protocol. Policies are generally adopted by a governance body within an organization. Policies can assist in both ''subjective'' and ''objective'' decision making. Policies used in subjective decision-making usually assist senior management with decisions that must be based on the relative merits of a number of factors, and as a result, are often hard to test objectively, e.g. work–life balance policy... Moreover, Governments and other institutions have policies in the form of laws, regulations, procedures, administrative actions, incentives and voluntary practices. Frequently, resource allocations mirror policy decisions. Policy is a blueprint of the organizational activities which are repetitive/routine in nature. In contrast, policies to assist in objective decision-making are usually operational in nature an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Podgorica
Podgorica (Cyrillic script, Cyrillic: Подгорица, ; Literal translation, lit. 'under the hill') is the Capital city, capital and List of cities and towns in Montenegro, largest city of Montenegro. The city was formerly known as Titograd (Cyrillic script, Cyrillic: Титоград, ) between 1946 and 1992—in the period that Montenegro formed, as the Socialist Republic of Montenegro in honour of Marshal of Yugoslavia, Marshal Josip Broz Tito. The city was largely destroyed during the bombing of Podgorica in World War II and accordingly the city is now dominated by architecture from the following decades of communism. Further but less substantial damage was caused by the NATO bombing of Yugoslavia, 1999 bombing by NATO forces. The surrounding landscape is predominantly Mountain range, mountainous terrain. The city is just north of the Lake Skadar and close to coastal destinations on the Adriatic Sea. Historically, it was Podgorica's position at the confluence of the Ribn ...

PostgreSQL
PostgreSQL (, ), also known as Postgres, is a free and open-source relational database management system (RDBMS) emphasizing extensibility and SQL compliance. It was originally named POSTGRES, referring to its origins as a successor to the Ingres database developed at the University of California, Berkeley. In 1996, the project was renamed to PostgreSQL to reflect its support for SQL. After a review in 2007, the development team decided to keep the name PostgreSQL and the alias Postgres. PostgreSQL features transactions with Atomicity, Consistency, Isolation, Durability (ACID) properties, automatically updatable views, materialized views, triggers, foreign keys, and stored procedures. It is designed to handle a range of workloads, from single machines to data warehouses or Web services with many concurrent users. It is the default database for macOS Server and is also available for Windows, Linux, FreeBSD, and OpenBSD. History PostgreSQL evolved from the Ingres proj ...

Picogram
To help compare different orders of magnitude, the following lists describe various mass levels between 10−59 kg and 1052 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe. Typically, an object having greater mass will also have greater weight (see mass versus weight), especially if the objects are subject to the same gravitational field strength. Units of mass The table at right is based on the kilogram (kg), the base unit of mass in the International System of Units ( SI). The kilogram is the only standard unit to include an SI prefix (''kilo-'') as part of its name. The ''gram'' (10−3 kg) is an SI derived unit of mass. However, the ''names'' of all SI mass units are based on ''gram'', rather than on ''kilogram''; thus 103 kg is a ''megagram'' (106 g), not a *''kilokilogram''. The ''tonne'' (t) is an SI-compatible unit of mass equal to a megagram (''Mg''), or 103 kg. The unit is in common use for m ...

Panzergewinde
The Stahlpanzerrohrgewinde (, "steel conduit thread") standard for screw threads, more often called by the shortened Panzergewinde (), was a technical standard created in Germany and subsequently used in Switzerland, Austria, and other neighboring European countries. It has been retracted. The thread is used to join pieces of electrical conduit and cable glands. Alternative stylings of the German name are ''Stahl-Panzer-Rohr-Gewinde'', an abbreviated form ''StaPa-Rohr-Gewinde'', and the acronym ''PG''. Overview The standard, codified by the ''Deutsches Institut für Normung'' (DIN, German Institute for Standardization), is DIN 40430. ''Panzergewinde'' sizes are named with the prefix ''PG'' plus a nominal number which approximately corresponds to the maximum cable diameter (in millimeters) that can be passed through the conduit. Because the walls of the conduit are usually relatively thin, the thread depth is limited. Thus a thread angle of 80° is used. The ''Verband der Ele ...

Paleogene
The Paleogene ( ; British English, also spelled Palaeogene or Palæogene; informally Lower Tertiary or Early Tertiary) is a geologic period, geologic period and system that spans 43 million years from the end of the Cretaceous Period million years ago (annum, Mya) to the beginning of the Neogene Period Mya. It is the beginning of the Cenozoic Era of the present Phanerozoic Eon. The earlier term Tertiary Period was used to define the span of time now covered by the Paleogene Period and subsequent Neogene Period; despite no longer being recognised as a formal stratigraphy, stratigraphic term, 'Tertiary' is still widely found in earth science literature and remains in informal use. Paleogene is often abbreviated "Pg" (but the United States Geological Survey uses the abbreviation PE for the Paleogene on the Survey's geologic maps). During the Paleogene, evolution of mammals, mammals diversified from relatively small, simple forms into a large group of diverse animals in the wake of ...

Pg (Unix)
pg is a terminal pager program on Unix and Unix-like systems for viewing text files. It can also be used to page through the output of a command via a pipe. pg uses an interface similar to vi, but commands are different. As of 2018, pg has been removed from the POSIX specification, but is still included in util-linux. Users are expected to use other paging programs, such as more, less or most. History pg is the name of the historical utility on BSD UNIX systems. It was written to address the limit of the historical more command not being able to traverse the input backward. Eventually that ability was added also to more, so both are quite similar. References See also * less * more * most (Unix) most is a terminal pager program on Unix, OpenVMS, MS-DOS, Windows and Unix-like systems used to view (but not change) the contents of a text file one screen at a time.

PG(3,2)
In finite geometry, PG(3,2) is the smallest three-dimensional projective space. It can be thought of as an extension of the Fano plane. It has 15 points, 35 lines, and 15 planes. It also has the following properties: * Each point is contained in 7 lines and 7 planes * Each line is contained in 3 planes and contains 3 points * Each plane contains 7 points and 7 lines * Each plane is isomorphic to the Fano plane * Every pair of distinct planes intersect in a line * A line and a plane not containing the line intersect in exactly one point Constructions Construction from ''K''6 Take a complete graph ''K''6. It has 15 edges, 15 perfect matchings and 20 triangles. Create a point for each of the 15 edges, and a line for each of the 20 triangles and 15 matchings. The incidence structure between each triangle or matching (line) to its three constituent edges (points), induces a PG(3,2). Construction from Fano planes Take a Fano plane and apply all 5040 permutations of its 7 points. Dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galois Geometry
Galois geometry (so named after the 19th-century French mathematician Évariste Galois) is the branch of finite geometry that is concerned with algebraic and analytic geometry over a finite field (or ''Galois field''). More narrowly, ''a'' Galois geometry may be defined as a projective space over a finite field. Objects of study include affine and projective spaces over finite fields and various structures that are contained in them. In particular, arcs, ovals, hyperovals, unitals, blocking sets, ovoids, caps, spreads and all finite analogues of structures found in non-finite geometries. Vector spaces defined over finite fields play a significant role, especially in construction methods. Projective spaces over finite fields Notation Although the generic notation of projective geometry is sometimes used, it is more common to denote projective spaces over finite fields by , where is the "geometric" dimension (see below), and is the order of the finite field (or Galois fiel ...

Prostaglandin
The prostaglandins (PG) are a group of physiologically active lipid compounds called eicosanoids having diverse hormone-like effects in animals. Prostaglandins have been found in almost every tissue in humans and other animals. They are derived enzymatically from the fatty acid arachidonic acid. Every prostaglandin contains 20 carbon atoms, including a 5-carbon ring. They are a subclass of eicosanoids and of the prostanoid class of fatty acid derivatives. The structural differences between prostaglandins account for their different biological activities. A given prostaglandin may have different and even opposite effects in different tissues in some cases. The ability of the same prostaglandin to stimulate a reaction in one tissue and inhibit the same reaction in another tissue is determined by the type of receptor to which the prostaglandin binds. They act as autocrine or paracrine factors with their target cells present in the immediate vicinity of the site of their secret ...
