Personal Protection Officer
A personal protection officer (PPO) is an officer of the Metropolitan Police Protection Command who is assigned for the personal protection of members of the British royal family, the prime minister, government ministers, ambassadors, visiting heads of state, and other individuals deemed to be at risk. Prior to a restructuring of the Metropolitan Police's armed protection commands between 2015 and 2017, protection of the royal family and protection of senior Government officials and diplomats was carried out by two separate commands, with PPOs assigned to individual royals for long periods and able to build up a close professional relationship. Following the merger of royal and diplomatic protection, individual PPOs rotate through a pool and may protect different individuals on different days. Incidents During the 2017 Westminster attack, an unnamed PPO providing protection to then Secretary of State for Defence Michael Fallon Sir Michael Cathel Fallon (born 14 May 1952) i ...

Pfadfinder Und Pfadfinderinnen Österreichs
Pfadfinder und Pfadfinderinnen Österreichs (PPÖ; ''Austrian Boy Scouts and Girl Guides'') is the largest Scouting and Guiding organization in Austria and the only one approved by World Association of Girl Guides and Girl Scouts (WAGGGS) and the World Organization of the Scout Movement (WOSM). The association claims more than 300 troops (local units) with more than 85,000 Scouts nationwide. WOSM and WAGGGS give quite smaller membership values for the PPÖ: 9,503 Scouts (as of 2013) and 10,508 Guides (as of 2003). The badge of the PPÖ is dark red with a white combination of a fleur-de-lis and a trefoil, the symbols of WOSM and WAGGGS, respectively. In the center of the crest is a lighter red-and-white shield bearing the heraldic colors of Austria. The badges of both supranational organizations are also used. Male Scouts wear a purple WOSM logo on their uniforms, females wear the WAGGGS trefoil in the same position. The association is member of the Austrian National Youth Counc ...

Proximal Policy Optimization
Proximal Policy Optimization (PPO) is a family of model-free reinforcement learning algorithms developed at OpenAI in 2017. PPO algorithms are policy gradient methods, which means that they search the space of policies rather than assigning values to state-action pairs. PPO algorithms have some of the benefits of trust region policy optimization (TRPO) algorithms, but they are simpler to implement, more general, and have better sample complexity. It is done by using a different objective function.

Praetorian Prefect
The praetorian prefect ( la, praefectus praetorio, el, ) was a high office in the Roman Empire. Originating as the commander of the Praetorian Guard, the office gradually acquired extensive legal and administrative functions, with its holders becoming the Emperor's chief aides. Under Constantine I, the office was much reduced in power and transformed into a purely civilian administrative post, while under his successors, territorially-defined praetorian prefectures emerged as the highest-level administrative division of the Empire. The prefects again functioned as the chief ministers of the state, with many laws addressed to them by name. In this role, praetorian prefects continued to be appointed by the Eastern Roman Empire (and the Ostrogothic Kingdom) until the reign of Heraclius in the 7th century AD, when wide-ranging reforms reduced their power and converted them to mere overseers of provincial administration. The last traces of the prefecture disappeared in the Byzantine Em ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Its first music director was Luis Valencia, with Julian Quirit serving as concertmaster. Six years later Imelda Marcos, then First Lady of the Philippines, asked Oscar Yatco to reorganize the ensemble, and in 1982 the "Philippine Philharmonic Orchestra" took its present name and adopted a new vision: to become a world-class symphony orchestra comparable with the finest.

Toray Pan Pacific Open
The Pan Pacific Open ( ja, 東レ パン・パシフィック・オープン・テニストーナメント), currently sponsored by Toray Industries, is a women's outdoor hardcourt tennis tournament held annually in Tokyo, Japan. It is a WTA 500-level tournament. The tournament was first held in 1976 as the ''Sillook Open'' in Tokyo. In 1982 it was renamed the ''TV Tennis Open'' and in 1983 it changed yet again to the ''Queens Grand Prix''.

Preferred Provider Organization
In U.S. health insurance, a preferred provider organization (PPO), sometimes referred to as a participating provider organization or preferred provider option, is a managed care organization of medical doctors, hospitals, and other health care providers who have agreed with an insurer or a third-party administrator to provide health care at reduced rates to the insurer's or administrator's clients.

A membership allows a substantial discount below the regularly charged rates of the designated professionals partnered with the organization.

They negotiate with providers to set fee schedules and handle disput ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Purchase Order
A purchase order is a commercial document and first official offer issued by a buyer to a seller, indicating types, quantities, and agreed prices for products or services.

Sellers are also protected by the use of purchase orders, in case of a buyer's refusal to pay for goods or services. Purchase orders ...

Pure Plant Oil
Vegetable oil can be used as an alternative fuel in diesel engines and in heating oil burners. When vegetable oil is used directly as a fuel, in either modified or unmodified equipment, it is referred to as straight vegetable oil (SVO) or pure plant oil (PPO). Conventional diesel engines can be modified to help ensure that the viscosity of the vegetable oil is low enough to allow proper atomization of the fuel. This prevents incomplete combustion, which would damage the engine by causing a build-up of carbon. Straight vegetable oil can also be blended with conventional diesel or processed into biodiesel, HVO or bioliquids for use under a wider range of conditions. History Rudolf Diesel was the father of the engine which bears his name. His first attempts were to design an engine to run on coal dust, but he later designed his engine to run on vegetable oil. The idea, he hoped, would make his engines more attractive to farmers having a source of fuel readily available. In a 1912 p ...

Personal Protection Order
A restraining order or protective order, is an order used by a court to protect a person in a situation involving alleged domestic violence, child abuse, assault, harassment, stalking, or sexual assault. Restraining and personal protection order laws vary from one jurisdiction to another but all establish who can file for an order, what protection or relief a person can get from such an order, and how the order will be enforced. The court will order the adverse party to refrain from certain actions or require compliance with certain provisions. Failure to comply is a violation of the order which can result in the arrest and prosecution of the offender. Violations in some jurisdictions may also constitute criminal or civil contempt of court. Restraining order provisions All protective order statutes permit the court to instruct an alleged abuser to stay a certain distance away from someone, such as their home, workplace or school ("stay away" provisions), and not to contact the ...
