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. :2 Pd + O2 → 2 PdO 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 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polydioxanone
Polydioxanone (PDO, PDS) or poly-''p''-dioxanone is a colorless, crystalline, biodegradable synthetic polymer. Chemistry Chemically, polydioxanone is a polymer of multiple repeating ether-ester units. It is obtained by ring-opening polymerization of the monomer ''p''-dioxanone. The process requires heat and an organometallic catalyst like zirconium acetylacetone or zinc L-lactate. It is characterized by a glass transition temperature in the range of −10 and 0 °C and a crystallinity of about 55%. For the production of sutures, polydioxanone is generally extruded into fibers, however care should be taken to process the polymer to the lowest possible temperature, in order to avoid its spontaneous depolymerization back to the monomer. The ether oxygen group in the backbone of the polymer chain is responsible for its flexibility. Medical use Polydioxanone is used for biomedical applications, particularly in the preparation of surgical sutures. Other biomedical applicatio ...

PHP Data Objects
PHP is a general-purpose scripting language geared toward web development. It was originally created by Danish-Canadian programmer Rasmus Lerdorf in 1993 and released in 1995. The PHP reference implementation is now produced by The PHP Group. PHP originally stood for ''Personal Home Page'', but it now stands for the recursive initialism ''PHP: Hypertext Preprocessor''. PHP code is usually processed on a web server by a PHP interpreter implemented as a module, a daemon or as a Common Gateway Interface (CGI) executable. On a web server, the result of the interpreted and executed PHP code which may be any type of data, such as generated HTML or binary image data would form the whole or part of an HTTP response. Various web template systems, web content management systems, and web frameworks exist which can be employed to orchestrate or facilitate the generation of that response. Additionally, PHP can be used for many programming tasks outside the web context, such as standalo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portable Distributed Objects
Portable Distributed Objects (PDO) is an application programming interface (API) for creating object-oriented code that can be executed remotely on a computer network, network of computers. It was created by NeXT Computer, Inc. using their OpenStep system, whose use of Objective-C made the package very easy to write. It was characterized by its very light weight and high speed in comparison to similar systems such as CORBA. Versions of PDO were available for Solaris (operating system), Solaris, HP-UX and all versions of the OPENSTEP system, although an agreement was also announced for a version to be made for Digital Unix, then still known as OSF/1, with delivery anticipated after versions for SunOS and Solaris had been released. Product licence pricing for these platforms varied from $2,500 for use on a "small server" up to $10,000 for use on a "large server". A version that worked with Microsoft Object Linking and Embedding, OLE was also available called ''D'OLE'', allowing distri ...

Process Data Object
CANopen is a communication protocol and device profile specification for embedded systems used in automation. In terms of the OSI model, CANopen implements the layers above and including the network layer. The CANopen standard consists of an addressing scheme, several small communication protocols and an application layer defined by a device profile. The communication protocols have support for network management, device monitoring and communication between nodes, including a simple transport layer for message segmentation/desegmentation. The lower level protocol implementing the data link and physical layers is usually Controller Area Network (CAN), although devices using some other means of communication (such as Ethernet Powerlink, EtherCAT) can also implement the CANopen device profile. The basic CANopen device and communication profiles are given in the CiA 301 specification released by CAN in Automation. Profiles for more specialized devices are built on top of this basic prof ...

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 warms ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 a small number of domestic (national) commercial flights. Padre Aldamiz International Airport is near some of Peru's noted ecological areas, such as the national jungle reserve of Tambopata-Candamo. Like many airports around the world, Padre Aldamiz International Airport benefits mostly from one type of traveler, in this case 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 all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ope ...
