Padre Aldamiz International Airport
Padre Aldamiz International Airport , also known as Puerto Maldonado International Airport, is an airport serving the city of Puerto Maldonado in the Madre de Dios Region of Peru. The airport oversees one domestic (national) airline with commercial flights. Padre Aldamiz International Airport is near some of Peru's noted ecological areas, such as the national jungle reserve of Tambopata-Candamo. Padre Aldamiz International Airport benefits mostly from one type of traveler, ecology tourists. Western doctors often warn that airport authorities require travelers to carry documentation informing about yellow fever vaccination because of its rainforest location. The airport was served by Peru's national airline, AeroPerú. AeroPerú ceased operations in 1999, and, subsequently, other airlines have entered the Lima to Puerto Maldonado air route. Nuevo Continente made an attempt in 2004, but that airline suspended operations amid allegations of drug trafficking by their owners. It ...

Advanced Statistics (ice Hockey)
In ice hockey, analytics is the analysis of the characteristics of hockey players and teams through the use of statistics and other tools to gain a greater understanding of the effects of their performance. Three commonly used basic statistics in ice hockey analytics are "Corsi" and " Fenwick", both of which use shot attempts to approximate puck possession, and "PDO", which is often considered a measure of luck. However, new statistics are being created every year, with "RAPM", regularized adjusted plus-minus, and "xG", expected goals, being created very recently in regards to hockey even though they have been around in other sports before. RAPM tries to isolate a player's play driving ability based on multiple factors, while xG tries to show how many goals a player is expected to add to their team independent of shooting and goalie talent. Hockey Hall of Fame coach Roger Nielson is credited as being an early pioneer of analytics and used measures of his own invention as early as ...

Pseudo-differential Operator
In mathematical analysis a pseudo-differential operator is an extension of the concept of differential operator. Pseudo-differential operators are used extensively in the theory of partial differential equations and quantum field theory, e.g. in mathematical models that include ultrametric pseudo-differential equations in a non-Archimedean space. History The study of pseudo-differential operators began in the mid 1960s with the work of Kohn, Nirenberg, Hörmander, Unterberger and Bokobza. They played an influential role in the second proof of the Atiyah–Singer index theorem via K-theory. Atiyah and Singer thanked Hörmander for assistance with understanding the theory of pseudo-differential operators. Motivation Linear differential operators with constant coefficients Consider a linear differential operator with constant coefficients, : P(D) := \sum_\alpha a_\alpha \, D^\alpha which acts on smooth functions u with compact support in R''n''. This operator can be writt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protected Designation Of Origin
The protected designation of origin (PDO) is a type of geographical indication of the European Union aimed at preserving the designations of origin of food-related products. The designation was created in 1992 and its main purpose is to designate products that have been produced, processed and developed in a specific geographical area, using the recognized know-how of local producers and ingredients from the region concerned. Features The characteristics of the products protected are essentially linked to their terroir. The European or UK PDO logo, of which the use is compulsory, documents this link. European Regulation 510/2006 of 20 March 2006 acknowledges a priority to establish a community protection system that ensures equal conditions of competition between producers. This European Regulation is intended to guarantee the reputation of regional products, adapt existing national protections to make them comply with the requirements of the World Trade Organization, and info ...

Petroleum Development Oman
Petroleum Development Oman (PDO) is the leading exploration and production company in the Sultanate of Oman. The Company delivers the majority of the country's crude oil production and natural gas supply. The company is owned by the Government of Oman (with a 60% interest), Royal Dutch Shell (34%), TotalEnergies (4%) and Partex (2%). The first economic oil find was made in 1962, and the first oil consignment was exported in 1967. History A geological survey of the country in 1925 by the D'Arcy Exploration Company found no conclusive evidence of oil. Twelve years later, when American geologists began intensively searching for oil in neighboring Saudi Arabia, Sultan Said bin Taimur granted a 75-year concession for central Oman to the Iraq Petroleum Company (IPC), and a separate concession for the province of Dhofar. Pausing only for the Second World War, exploration for oil was under way in Oman. IPC created an associate company, Petroleum Development (Oman and Dhofar) Ltd, to ...

Performing The Duties Of
The Federal Vacancies Reform Act of 1998 (commonly called the Vacancies Act) ( ''et seq.'') is a United States federal statute establishing the procedure for filling vacancies in an appointed office of an executive agency of the government before the appointment of a permanent replacement. The Act allows an incoming President 300 days in which to temporarily and unilaterally fill positions with "acting" officers. After this initial extended period, the offices officially become vacant and the President has 210 days to fill the vacancies. However, provisions in the Act, described as a loophole, allow the president after these periods to assign the "nonexclusive duties" of a vacant position to a person to perform, provided they are not described as "acting". The de facto acting officers can be described as “performing the duties of...”, or similar description. Provisions The law revises provisions relating to the filling of federal vacancies to authorize the president, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Decadal Oscillation
The Pacific decadal oscillation (PDO) is a robust, recurring pattern of ocean-atmosphere climate variability centered over the mid-latitude Pacific basin. The PDO is detected as warm or cool surface waters in the Pacific Ocean, north of 20°N. Over the past century, the amplitude of this climate pattern has varied irregularly at interannual-to-interdecadal time scales (meaning time periods of a few years to as much as time periods of multiple decades). There is evidence of reversals in the prevailing polarity (meaning changes in cool surface waters versus warm surface waters within the region) of the oscillation occurring around 1925, 1947, and 1977; the last two reversals corresponded with dramatic shifts in salmon production regimes in the North Pacific Ocean. This climate pattern also affects coastal sea and continental surface air temperatures from Alaska to California. During a " warm", or "positive", phase, the west Pacific becomes cooler and part of the eastern ocean warm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palladium(II) Oxide
Palladium(II) oxide is the inorganic compound of formula Pd O. It is the only well characterised oxide of palladium. It is prepared by treating the metal with oxygen. Above about 900 °C, the oxide reverts to palladium metal and oxygen gas. It is not attacked by acids. Structure The structure of PdO is tetragonal (''P''42/''mmc'') ''a'' = 3.044, ''c'' = 5.328 Å. The Pd atoms are square planar as expected for a d8 metal ion and the oxygen atoms are approximately tetrahedral. The closest Pd–Pd distance is 3.044 Å and is almost within the range which can be considered a bonding distance. Preparation PdO is often obtained as a poorly defined material that is generated for applications as a catalyst. Palladium oxide is prepared by heating palladium sponge metal in oxygen at 350 °C. : The oxide is obtained as a black powder. The oxide also may be prepared specially for catalytic use by heating variously a mixture of palladium(II) chloride and potassium nitra ...
