Problem: Hydrogen:

The electrolysis of water is a simple method of producing hydrogen. A low voltage current is run through the water, and gaseous oxygen forms at the anode while gaseous hydrogen forms at the cathode. Typically the cathode is made from platinum or another inert metal when producing hydrogen for storage. If, however, the gas is to be burnt on site, oxygen is desirable to assist the combustion, and so both electrodes would be made from inert metals. (Iron, for instance, would oxidize, and thus decrease the amount of oxygen given off.) The theoretical maximum efficiency (electricity used vs. energetic value of hydrogen produced) is in the range 8094%.

Where does the gaseous oxygen form at?

A: anode

Problem: In a 1986 interview, Rocky Jones, the former club DJ who ran the D.J. International record label, doesn't mention Importes Etc., Frankie Knuckles, or the Warehouse by name, but agrees that "house" was a regional catch-all term for dance music, and that it was once synonymous with older disco music.
For what kind of music was Jones a regional catch-all term?

Some video compression schemes typically operate on square-shaped groups of neighboring pixels, often called macroblocks. These pixel groups or blocks of pixels are compared from one frame to the next, and the video compression codec sends only the differences within those blocks. In areas of video with more motion, the compression must encode more data to keep up with the larger number of pixels that are changing. Commonly during explosions, flames, flocks of animals, and in some panning shots, the high-frequency detail leads to quality decreases or to increases in the variable bitrate.
What compression typically operate on square-shaped groups of pixels?
A: video

Context and question: According to filings to the Canadian Radio-television and Telecommunications Commission (CRTC) by Thunder Bay Electronics (owner of CBC's Thunder Bay affiliate CKPR-DT) and Bell Media (owner of CBC affiliates CFTK-TV in Terrace and CJDC-TV in Dawson Creek),[citation needed] the CBC informed them that it will not extend its association with any of its private affiliates beyond August 31, 2011. Incidentally, that was also the date for analogue to digital transition in Canada. Given recent practice and the CBC's decision not to convert any retransmitters to digital, even in markets with populations in the hundreds in thousands, it is not expected that the CBC will open new transmitters to replace its affiliates, and indeed may pare back its existing transmitter network. However, in March 2011, CKPR announced that it had come to a programming agreement with the CBC, in which the station will continue to provide CBC programming in Thunder Bay for a period of five years. On March 16, 2012, Astral Media announced the sale of its assets to Bell Media, owners of CTV and CTV Two, for $3.38 billion with CFTK and CJDC included in the acquisition. Whether the stations will remain CBC affiliates or become owned-and-operated stations of CTV or CTV Two following the completion of the merger is undetermined.
In March 2011, CBC and CKPR agreed to continue working together for how many additional years?
Answer: five

Question: While videoconferencing technology was initially used primarily within internal corporate communication networks, one of the first community service usages of the technology started in 1992 through a unique partnership with PictureTel and IBM Corporations which at the time were promoting a jointly developed desktop based videoconferencing product known as the PCS/1. Over the next 15 years, Project DIANE (Diversified Information and Assistance Network) grew to utilize a variety of videoconferencing platforms to create a multi-state cooperative public service and distance education network consisting of several hundred schools, neighborhood centers, libraries, science museums, zoos and parks, public assistance centers, and other community oriented organizations.
Is there an answer to this question: What did IBM Corporations grow to create over the next 15 years?

The revisionist paleontologist Robert T. Bakker, who published his findings as The Dinosaur Heresies, treated the mainstream view of dinosaurs as dogma. "I have enormous respect for dinosaur paleontologists past and present. But on average, for the last fifty years, the field hasn't tested dinosaur orthodoxy severely enough." page 27 "Most taxonomists, however, have viewed such new terminology as dangerously destabilizing to the traditional and well-known scheme..." page 462. This book apparently influenced Jurassic Park. The illustrations by the author show dinosaurs in very active poses, in contrast to the traditional perception of lethargy. He is an example of a recent scientific endoheretic.
What label is associated with Robert T. Bakker as a result of his work?
A:
endoheretic
