Open Educational Resources
Open educational resources (OER) are Instructional materials, teaching, learning, and research materials intentionally created and Free license, licensed to be free for the end user to own, share, and in most cases, modify. The term "OER" describes publicly accessible materials and resources for any user to use, re-mix, improve, and redistribute under some licenses. These are designed to reduce accessibility barriers by implementing best practices in teaching and to be adapted for local unique contexts.Mishra, M., Dash, M. K., Sudarsan, D., Santos, C. A. G., Mishra, S. K., Kar, D., ... & da Silva, R. M. (2022). Assessment of trend and current pattern of open educational resources: A bibliometric analysis. ''The Journal of Academic Librarianship'', ''48''(3), 102520. The development and promotion of open educational resources is often motivated by a desire to provide an alternative or enhanced educational paradigm.

IATA Airport Code
An IATA airport code, also known as an IATA location identifier, IATA station code, or simply a location identifier, is a three-character alphanumeric geocode designating many airports and metropolitan areas around the world, defined by the International Air Transport Association (IATA). The characters prominently displayed on baggage tags attached at airport check-in desks are an example of a way these codes are used. The assignment of these codes is governed by IATA Resolution 763, and it is administered by the IATA's headquarters in Montreal, Canada. The codes are published semi-annually in the IATA Airline Coding Directory. IATA provides codes for airport handling entities, and for certain railway stations. Alphabetical lists of airports sorted by IATA code are available. A list of railway station codes, shared in agreements between airlines and rail lines such as Amtrak, SNCF, and , is available. However, many railway administrations have their own list of codes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Örnsköldsvik Airport
Örnsköldsvik Airport , is a regional airport located northeast of Örnsköldsvik, Sweden, at Husum Husum (, frr, Hüsem) is the capital of the ''Kreis'' (district) Nordfriesland in Schleswig-Holstein, Germany. The town was the birthplace of the novelist Theodor Storm, who coined the epithet "the grey town by the sea". It is also the home of ..., built in 1961. History The airport had 80,123 passengers in 2013 and a record of 165,712 in 2000. On 31 October 2014, Örnsköldsvik airport received permission to have the first remote controlled air control tower in the world. The tower is controlled from Sundsvall-Timrå Airport.

Offense Efficiency Rating
In basketball statistics, Offensive Efficiency Rating (OER) is the average number of points scored by a basketball player per shot taken. This includes missed field goals as well as free throws. The statistic stems from the previously created Player Efficiency Rating (PER). The per-minute rating was created by John Hollinger John Hollinger (born May 17, 1971) is the former Vice President of Basketball Operations for the Memphis Grizzlies of the National Basketball Association (NBA) and current Senior NBA columnist at The Athletic. Prior to December 2012, he was an a .... Hollinger states, "The PER sums up all a player's positive accomplishments, subtracts the negative accomplishments, and returns a per-minute rating of a player's performance."

Oregon Electric Railway
The Oregon Electric Railway (OE) was an interurban railroad line in the U.S. state of Oregon that linked Portland to Eugene. Service from Portland to Salem began in January 1908. The Spokane, Portland and Seattle Railway purchased the system in 1910, and extended service to Eugene in 1912. Regular passenger service in the Willamette Valley ended in May 1933. Freight operations continued and the railway survived into the 1990s, ultimately as a Burlington Northern feeder. Operation as an electric railroad ended July 10, 1945. The tracks run parallel to the main modern Union Pacific line between Portland and Eugene, used for freight and passenger service. The OE line is to the west, closely following the Willamette River. In the 2000s, the line has been under consideration as an alternative for Amtrak's Cascades and Coast Starlight passenger lines. Removing passenger service from the clogged Union Pacific track would improve the timeliness of the trains, permit higher capacity, an ...

Odakyu Electric Railway
, commonly known as Odakyū, is a major railway company based in Tokyo, Japan, best known for its ''Romancecar'' series of limited express trains from Tokyo to Odawara, Enoshima, Tama New Town, and Hakone. The Odakyu Electric Railway Company forms the core of the Odakyu Group, which comprises 101 companies (as of July 14, 2017) and includes the Enoshima Electric Railway, Hakone Tozan Railway, , , and hotel. It is listed on the Tokyo Stock Exchange and is a constituent of the Nikkei 225. History Pre-WWII The 83 km line from Shinjuku to Odawara opened for service on April 1, 1927. Unlike the Odawara line, rarely were pre-World War II Japanese private railways constructed with double-track and fully electrified from the first day of operation. Two years later, April 1, 1929, the Enoshima Line was added. The original full name of the railroad was , but this was often shortened to . The abbreviation ''Odakyu'' was made popular by the title song of the 1929 movie '' Tōkyō k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxygen Enhancement Ratio
The oxygen enhancement ratio (OER) or oxygen enhancement effect in radiobiology refers to the enhancement of therapeutic or detrimental effect of ionizing radiation due to the presence of oxygen. This so-called oxygen effect is most notable when cells are exposed to an ionizing radiation dose. The OER is traditionally defined as the ratio of radiation doses during lack of oxygen compared to no lack of oxygen for the same biological effect. This may give varying numerical values depending on the chosen biological effect. Additionally, OER may be presented in terms of hyperoxic environments and/or with altered oxygen baseline, complicating the significance of this value. :OER = \frac The maximum OER depends mainly on the ionizing density or LET of the radiation. Radiation with higher LET and higher relative biological effectiveness (RBE) have a lower OER in mammalian cell tissues. The value of the maximum OER varies from about 1–4. The maximum OER ranges from about 2–4 for l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heterogeneous Water Oxidation
Water oxidation is one of the half reactions of water splitting: 2H2O → O2 + 4H+ + 4e− Oxidation (generation of dioxygen) 4H+ + 4e− → 2H2redox, Reduction (generation of dihydrogen) 2H2O → 2H2 + O2Total Reaction Of the two half reactions, the oxidation step is the most demanding because it requires the coupling of 4 electron and proton transfers and the formation of an oxygen-oxygen bond. This process occurs naturally in plants photosystem II to provide protons and electrons for the photosynthesis process and release oxygen to the atmosphere, as well as in some electrowinning processes. Since hydrogen can be used as an alternative clean burning fuel, there has been a need to split water efficiently. However, there are known materials that can mediate the reduction step efficiently therefore much of the current research is aimed at the oxidation half reaction also known as the Oxygen Evolution Reaction (OER). Current research focuses on understanding the mechanism of OER ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
