Some of the helium-3 found in the terrestrial atmosphere is also a relic of atmospheric and underwater nuclear weapons testing, conducted by the three big nuclear powers before 1963.

Some of these mammals would evolve into large forms that would dominate the land, while others would become capable of living in marine, specialized terrestrial, and airborne environments.

Some terrestrial telescopes ( such as the Very Large Telescope ) can reduce atmospheric effects with adaptive optics.

Some salamander species are fully aquatic throughout life, some take to the water intermittently, and some are entirely terrestrial as adults.

Some salamanders that are terrestrial have lungs that are used in respiration, although these are simple and sac-like, unlike the more complex organs found in mammals.

Some terrestrial species lack both lungs and gills and perform gas exchange through their skin, a process known as valerian respiration in which the capillary beds are spread throughout the epidermis, and inside the mouth.

Some particle physics experiments must adjust for terrestrial tides.

Some orders of heterotardigrades are marine, others are terrestrial, but as for all tardigrades, all are aquatic in the sense that they must be surrounded by at least a film of moisture in order to be active-though they can survive in a dormant state if the habitat dries out.

Some diplurans have the ability to shed their cerci if necessary ( autotomy ); of all terrestrial arthropods, only diplurans have the ability to regenerate these lost appendages over a series of moults.

Some populations of the North American caribou migrate the furthest of any terrestrial mammal, travelling up to a year, and covering.

Some ecosystems, such as many wetlands, do not organize as a strict pyramid, because aquatic plants are not as productive as long-lived terrestrial plants such as trees.

Some of the more familiar and better-known gastropods are terrestrial gastropods ( the land snails and slugs ) and some live in freshwater, but more than two thirds of all named species live in a marine environment.

Some botanists however split Huperzia into two genera, Huperzia in the narrow sense including 10-15 species of terrestrial temperate to Arctic species, and the rest in Phlegmariurus, a primarily tropical to subtropical genus of mainly epiphytic species.

Some terrestrial mammals, especially desert rodents appear to survive without drinking but they do generate water through the metabolism of cereal seeds and they also have mechanisms to conserve water to the maximum degree.

Some terrestrial ecosystems – for example, those of the open deserts and similar arid environments – exist on irregular rainfall and the moisture it delivers to the soil, supplemented by moisture in the air.

Some digital broadcasting systems allow single-frequency network ( SFN ), where all terrestrial transmitters in a region sending the same multiplex of radio programs may use the same frequency channel without self-interference problems, further improving the system spectral efficiency.

Some MATV systems may carry 8-VSB and QAM signals, mostly in apartment buildings and similar facilities that use a combination of terrestrial antennas and cable distribution sources ( such as HITS or " Headend in the Sky ", a unit of Comcast that delivers digital channels by satellite to small cable systems ).

Some exposed outcrops appear to show faint layering, and some researchers also believe that landforms visible in images of the mouth of Ma ' adim Vallis where it enters Gusev resemble landforms seen in some terrestrial river deltas.

Some species are terrestrial and are found under logs, in or on the soil, and on plants in humid areas.

Some structures resembling the mineralized casts of terrestrial bacteria and their appendages ( fibrils ) or by-products ( extracellular polymeric substances ) occur in the rims of carbonate globules and preterrestrial aqueous alteration regions.

Some parts of the world, notably in France and the US, have also offered encrypted analog terrestrial signals, available for subscription.

Some terrestrial species throw a thread of mucus which they use as a rope to climb from one leaf to another.

Some networks use 32 kbit / s ADPCM on the terrestrial side of the network instead of 64 kbit / s PCM and the TRAU converts accordingly.

Some 500 species are found in fresh water ; and another 5, 000 species are the woodlice in the suborder Oniscidea, which are thus by far the most successful group of terrestrial crustaceans.

Some amateur astronomers use home-made radio telescopes, while others use radio telescopes that were originally built for astronomy research but have since been made available for use by amateurs.

Some offer access thfough packet switched networks, or packet radio connections.

Some codes beginning with VE and VF are also in use to identify radio repeater transmitters.

Some observers argued that this influenced the CRTC's June 2005 decision to ease Canadian content restrictions on satellite radio ( see above ).

Some music radio is broadcast by public service organizations, such as National Public Radio or the BBC.

Some combination systems include basic turntables with a CD and radio in retro-styled cabinets.

Some have expanded into radio shows.

Some clusters of radio and electronics stores were created or added to in the Canal Street and Union Square areas.

Some prominent examples of liberal talk radio shows currently in national syndication include: Dial Global talk show hosts Ed Schultz, Stephanie Miller, Thom Hartmann, and Bill Press ; The Young Turks ; Fox News host Alan Colmes, First Amendment Radio Network Libertarian host Jon Arthur, self-distributed Norman Goldman and Mike Malloy, and Premiere's Randi Rhodes.

Some notable British talk radio presenters include Tommy Boyd, James Whale, Steve Allen, Jon Gaunt, Nick Abbot, James Stannage, George Galloway, Ian Collins, Brian Hayes, Scottie McClue, Nicky Campbell and Simon Mayo.

Some later V-2s used " guide beams ", radio signals transmitted from the ground, to keep the missile on course, but the first models used a simple analog computer that adjusted the azimuth for the rocket, and the flying distance was controlled by the timing of the engine cut-off, " Brennschluss ", ground controlled by a Doppler system or by different types of on-board integrating accelerometers.

Some of the double agents were informed in radio messages from Germany after the invasion that they had been awarded the Iron Cross.

Some types of radio receiver circuits have a stronger capture effect than others.

Some of the more notable frequency bands used by radio telescopes include:

Some televised concerts offered a stereo simulcast soundtrack on FM radio and as such, events like Live Aid were recorded by thousands of people with a full stereo soundtrack despite the fact that stereo TV broadcasts were some years off ( especially in regions that adopted NICAM ).

Some radio stations report spins of the newest and most popular songs to industry publications.

Some of the many storytellers and monologists on early 1920s American radio might be able to claim even earlier dates.

Some instant messaging companies are also offering desktop sharing, IP radio, and IPTV to the voice and video features.

Some of the biggest telecommunications companies, TV and radio stations, newspapers, magazines, and web portals are based in Sofia, including the Bulgarian National Television, bTV and Nova TV.

Some major uses of the shortwave radio band are:

" Some came from their sketch series on a local radio station in Chicago and had to be lengthened from the " two-minute bits " that they were originally, while several others were stage sketches performed in a comedy club in Santa Monica.

Some slices were internally sprayed with nickel paint to meet electromagnetic and radio emissions regulations .</ li >

Some of the transmissions Komarov made were recorded by amateur radio operators like Sven Grahn.
