Australian PGA Championship
The Australian PGA Championship is a golf tournament on the PGA Tour of Australasia. It is the home tournament of the Australian PGA. Since 2000 it has been held in the South East Queensland region. The tournament was part of the OneAsia Tour from 2009 to 2014, and it has been co-sanctioned with the European Tour from 2015 to 2019 and again in 2022. The championship started in 1929, when the Australian Golf Union decided to hold the Australian Professional Championship during their annual championship meeting. The leading 16 professionals in the Open championship qualified for the match play event, with four rounds of matches over 36 holes. The winner, Rufus Stewart, received the ''Joe Kirkwood Cup'', donated by Australian golfer Joe Kirkwood Sr. After World War II the PGA of Australia took over the organisation of the championship. It continued to be a match-play event until 1964, when it became a 72-hole stroke-play tournament. Kel Nagle holds the record for the most wins, ...

Plane-based Geometric Algebra
Plane-based geometric algebra is an application of Clifford algebra to modelling planes, lines, points, and rigid transformations. Generally this is with the goal of solving applied problems involving these elements and their intersections, Projection (linear algebra), projections, and their angle from one another in 3D space. Originally growing out of research on spin groups, it was developed with applications to robotics in mind. It has since been applied to machine learning, rigid body dynamics, and computer science, especially computer graphics. It is usually combined with a ''duality'' operation into a system known as "Projective Geometric Algebra", see below. Plane-based geometric algebra takes ''planar reflections'' as basic elements, and constructs all other transformations and geometric objects out of them. Formally: it identifies planar reflections with the ''grade-1'' elements of a Clifford Algebra, that is, elements that are written with a single subscript such as "\bo ...

Juba Arabic
Juba Arabic (, ; ), also known since 2011 as South Sudanese Arabic, is a lingua franca spoken mainly in Equatoria Province in South Sudan, and derives its name from the South Sudanese capital, Juba. It is also spoken among communities of people from South Sudan living in towns in Sudan. The pidgin developed in the 19th century, among descendants of Sudanese soldiers, many of whom were recruited from southern Sudan. Residents of other large towns in South Sudan South Sudan (), officially the Republic of South Sudan, is a landlocked country in East Africa. It is bordered on the north by Sudan; on the east by Ethiopia; on the south by the Democratic Republic of the Congo, Uganda and Kenya; and on the ..., notably Malakal and Wau, South Sudan, Wau, do not generally speak Juba Arabic, tending towards the use of Arabic closer to Sudanese Arabic, in addition to local languages.

ISO 639-3
ISO 639-3:2007, ''Codes for the representation of names of languages – Part 3: Alpha-3 code for comprehensive coverage of languages'', is an international standard for language codes in the ISO 639 series. It defines three-letter codes for identifying languages. The standard was published by International Organization for Standardization (ISO) on 1 February 2007. As of 2023, this edition of the standard has been officially withdrawn and replaced by ISO 639:2023. ISO 639-3 extends the ISO 639-2 alpha-3 codes with an aim to cover all known natural languages. The extended language coverage was based primarily on the language codes used in the ''Ethnologue'' (volumes 10–14) published by SIL International, which is now the registration authority for ISO 639-3. It provides an enumeration of languages as complete as possible, including living and extinct, ancient and constructed, major and minor, written and unwritten. However, it does not include reconstructed languages su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peak Ground Acceleration
Peak ground acceleration (PGA) is equal to the maximum ground acceleration that occurred during earthquake shaking at a location. PGA is equal to the amplitude of the largest absolute acceleration recorded on an wikt:accelerogram, accelerogram at a site during a particular earthquake. Earthquake shaking generally occurs in all three directions. Therefore, PGA is often split into the horizontal and vertical components. Horizontal PGAs are generally larger than those in the vertical direction but this is not always true, especially close to large earthquakes. PGA is an important parameter (also known as an intensity measure) for earthquake engineering, The design basis earthquake ground motion (DBEGM) is often defined in terms of PGA. Unlike the Richter magnitude scale, Richter and Moment magnitude scale, moment magnitude scales, it is not a measure of the total seismic scales#Magnitude and intensity, energy (magnitude, or size) of an earthquake, but rather of how much the earth shake ...

Prostaglandin
Prostaglandins (PG) are a group of physiology, physiologically active lipid compounds called eicosanoids that have diverse hormone-like effects in animals. Prostaglandins have been found in almost every Tissue (biology), tissue in humans and other animals. They are derived enzymatically from the fatty acid arachidonic acid. Every prostaglandin contains 20 carbon atoms, including a carbon ring, 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 (biochemistry), receptor to which the prostaglandin binds. They act as autocrine or paracrine factors with their target cells ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polyglycolide
Polyglycolide or poly(glycolic acid) (PGA), also spelled as polyglycolic acid, is a biodegradable, thermoplastic polymer and the simplest linear, aliphatic polyester. It can be prepared starting from glycolic acid by means of polycondensation or ring-opening polymerization. PGA has been known since 1954 as a tough fiber-forming polymer. Owing to its hydrolytic instability, however, its use was slow to develop. Polyglycolide and its copolymers ( poly(lactic-''co''-glycolic acid) with lactic acid, poly(glycolide-''co''-caprolactone) with ε-caprolactone and poly (glycolide-''co''-trimethylene carbonate) with trimethylene carbonate) are widely used as a material for the synthesis of absorbable sutures and are being evaluated in the biomedical field. Physical properties Polyglycolide has a glass transition temperature between 35 and 40 °C and a melting point in the range of 225 to 230 °C. PGA also exhibits an elevated degree of crystallinity, around 45–55%, thus r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyglutamic Acid
Polyglutamic acid (PGA) is a polymer of the amino acid glutamic acid (GA). Depending on where the individual monomers connect, PGA can be gamma PGA (poly-γ-glutamic acid, γ-PGA), the form where the peptide bonds are between the amino group of GA and the carboxyl group at the end of the GA side chain, or alpha PGA, the form where the alpha-carboxyl is used to form the peptide bond. Gamma PGA is formed by bacterial fermentation. It is a major constituent of the Japanese food nattō and has a wide range of uses. Alpha PGA has been investigated as a drug delivery system. Structure Both form of PGA are linked together by peptide bonds. Because the glutamic acid has a chiral center, both forms of PGA can be made from L-glutamic acid, D-glutamic acid, or a mixture of both. In practical use, alpha PGA is composed mostly of L-glutamic acid, while gamma PGA tends to have a mixture of both. Properties Gamma PGA is non-immunogenic and biodegradable. It hydrolyzes in hot water. Both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3-Phosphoglyceric Acid
3-Phosphoglyceric acid (3PG, 3-PGA, or PGA) is the conjugate acid of 3-phosphoglycerate or glycerate 3-phosphate (GP or G3P). This glycerate is a biochemically significant metabolic intermediate in both glycolysis and the Calvin-Benson cycle. The anion is often termed as PGA when referring to the Calvin-Benson cycle. In the Calvin-Benson cycle, 3-phosphoglycerate is typically the product of the spontaneous scission of an unstable 6-carbon intermediate formed upon CO2 fixation. Thus, two equivalents of 3-phosphoglycerate are produced for each molecule of CO2 that is fixed. In glycolysis, 3-phosphoglycerate is an intermediate following the dephosphorylation ( reduction) of 1,3-bisphosphoglycerate. Glycolysis In the glycolytic pathway, 1,3-bisphosphoglycerate is dephosphorylated to form 3-phosphoglyceric acid in a coupled reaction producing two ATP via substrate-level phosphorylation. The single phosphate group left on the 3-PGA molecule then moves from an end carbon to a centr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
