Pentatricopeptide Repeat
The pentatricopeptide repeat (PPR) is a 35-amino acid sequence motif. Pentatricopeptide-repeat-containing proteins are a family of proteins commonly found in the plant kingdom. They are distinguished by the presence of tandem degenerate PPR motifs and by the relative lack of introns in the genes coding for them. Approximately 450 such proteins have been identified in the Arabidopsis genome, and another 477 in the rice genome. Despite the large size of the protein family, genetic data suggest that there is little or no redundancy of function between the PPR proteins in ''Arabidopsis''. The purpose of PPR proteins is currently under dispute. It has been shown that a good deal of those in ''Arabidopsis'' interact (often essentially) with mitochondria and other organelles and that they are possibly involved in RNA editing. However many trans proteins are required for this editing to occur and research continues to look at which proteins are needed. The structure of the PPR has ...

Projection Pursuit Regression
In statistics, projection pursuit regression (PPR) is a statistical model developed by Jerome H. Friedman and Werner Stuetzle which is an extension of additive models. This model adapts the additive models in that it first projects the data matrix (multivariate statistics), data matrix of explanatory variables in the optimal direction before applying smoothing functions to these explanatory variables. Model overview The model consists of linear combinations of ridge functions: non-linear transformations of linear combinations of the explanatory variables. The basic model takes the form :y_i=\beta_0 + \sum_^r f_j (\beta_j^x_i) + \varepsilon_i , where ''xi'' is a 1 × ''p'' row of the design matrix containing the explanatory variables for example ''i'', ''yi'' is a 1 × 1 prediction, is a collection of ''r'' vectors (each a unit vector of length ''p'') which contain the unknown parameters, is a collection of ''r'' initially unknown smooth functions that map from ℝ → ℝ, an ...

Portland Pattern Repository
The Portland Pattern Repository (PPR) is a repository for computer programming software design patterns. It was accompanied by a companion website, WikiWikiWeb, which was the world's first wiki. The repository has an emphasis on Extreme Programming, and it is hosted by Cunningham & Cunningham (C2) of Portland, Oregon. The PPR's motto is "People, Projects & Patterns". History On 17 September 1987, programmer Ward Cunningham, then with Tektronix, and Apple Computer's Kent Beck co-published the paper "Using Pattern Languages for Object-Oriented Programs" This paper, about software design patterns, was inspired by Christopher Alexander's architectural concept of "patterns" It was written for the 1987 OOPSLA programming conference organized by the Association for Computing Machinery. Cunningham and Beck's idea became popular among programmers because it helped them exchange programming ideas in a format that is easy to understand.

Polypropylene Random Copolymer
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene. Polypropylene belongs to the group of polyolefins and is partially crystalline and Chemical polarity#Nonpolar molecules, non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat-resistant. It is a white, mechanically rugged material and has a high chemical resistance. Bio-PP is the Drop-in bioplastic, bio-based counterpart of polypropylene (PP). Polypropylene is the second-most widely produced Commodity plastics, commodity plastic (after polyethylene). In 2019, the global market for polypropylene was worth $126.03 billion. Revenues are expected to exceed US$145 billion by 2019. The sales of this material are forecast to grow at a rate of 5.8% per year until 2021. History Phillips Petroleum chemists J. Paul Hogan and Robert Banks (chemist), Robert Banks f ...

Peste Des Petits Ruminants
Ovine rinderpest, also commonly known as ''peste des petits ruminants'' (PPR), is a contagious disease primarily affecting goats and sheep; however, camels and wild small ruminants can also be affected. PPR is currently present in North, Central, West and East Africa, the Middle East, and South Asia. It is caused by ''small ruminants morbillivirus'' in the genus ''Morbillivirus,'' and is closely related to, among others,'' rinderpest morbillivirus, measles morbillivirus'', and ''canine morbillivirus'' (previously known as canine distemper virus). The disease is highly contagious, and can have an 80–100% mortality rate in acute cases in an epizootic setting. The virus does not infect humans. The disease was first described in 1942 in Côte d'Ivoire, and has since been detected in more than 70 countries in the world. In 2017, the disease was reported to be affecting saiga in Mongolia, causing near-catastrophic herd depletion for the endangered species. In 2018, it was stat ...

Polska Partia Robotnicza
The Polish Workers' Party ( pl, Polska Partia Robotnicza, PPR) was a communist party in Poland from 1942 to 1948. It was founded as a reconstitution of the Communist Party of Poland (KPP) and merged with the Polish Socialist Party (PPS) in 1948 to form the Polish United Workers' Party (PZPR). From the end of World War II the PPR ruled Poland, with the Soviet Union exercising moderate influence. During the PPR years, the conspiratorial as well as legally permitted centers of opposition activity were largely eliminated, while a communist (also characterized as socialist) system was gradually established in the country. Arriving from the Soviet Union, a group of Polish communists was parachuted into occupied Poland in December 1941. With Joseph Stalin's permission, in January 1942 they established the Polish Workers' Party, a new communist party. The PPR established a partisan military organization '' Gwardia Ludowa'', later renamed '' Armia Ludowa''. In November 1943, W ...
