Most countries generate electricity in large centralized facilities, such as fossil fuel ( coal, gas powered ), nuclear, large solar power plants or hydropower plants.

Most notably, in the episode, Janet's bragging about herself doesn't appear to be empty bragging and she constantly raves about how " proof " is needed for all extraordinary claims, prompting her to force Arnold to collect " proof " from every planet in the solar system, so she can prove to the students in her class that she actually traveled to all the planets.

Most aliens are from different planets, who have a source of origin near the Solar System and in the Milky Way Galaxy, although, unlike the Marvel Universe, alien colonies are common within the solar system.

Most proposed designs for solar thermal rockets use hydrogen as their propellant due to its low molecular weight which gives excellent specific impulse of up to 1000 seconds ( 10 kN · s / kg ) using heat exchangers made of rhenium.

Most commonly, five such higher-order cycles in a modified vigesimal ( base-20 ) count were used, generating a linear progression of days to span a period of roughly 5125 solar years.

Most recently, the NTT helped detect a disc around a massive young star, solving the mystery of star formation in massive stars, and its observations were crucial to determine how asteroids are modified by solar wind.

Most coronagraphs are intended to view the corona of the Sun, but a new class of conceptually similar instruments ( called stellar coronagraphs to distinguish them from solar coronagraphs ) are being used to find extrasolar planets around nearby stars.

Most designs featured a cluster of modules at the lower end and a set of articulated solar arrays at the upper end.

Most tropical rainforests are located around and near the equator, therefore having what is called an equatorial climate characterized by three major climatic parameters: temperature, rainfall, and dry season intensity Other parameters that effect tropical rainforests are carbon dioxide concentrations, solar radiation, and nitrogen availability.

Most self-service huts have solar panels, and therefore electricity, but no running water, so they are usually located very close to a river from which buckets may be filled.

Most of the Junkers were above the blinding light of the flares, and the radar-controlled shore gun had been knocked out by one of the first sticks of bombs.

Most ejections originate from active regions on Sun's surface, such as groupings of sunspots associated with frequent flares.

Most ejections originate from active regions on the surface, such as groupings of sunspots associated with frequent flares.

Most weak flares do not have associated CMEs ; most powerful ones do.

Most industrial plant flares have a vapor-liquid separator ( also known as a knockout drum ) upstream of the flare to remove any large amounts of liquid that may accompany the relieved gases.

Most naturally occurring elements exist as a mixture of isotopes, and the average atomic mass of this mixture determines the element's atomic weight.

Most agates occur as nodules in volcanic rocks or ancient lavas where they represent cavities originally produced by the disengagement of volatiles in the molten mass which were then filled, wholly or partially, by siliceous matter deposited in regular layers upon the walls.

Most of the EDA vendors produced EDIF 2 0 0 translators, but they were definitely more interested in generating high-quality EDIF readers, and they had absolutely no motivation at all to write any software that generated EDIF ( an EDIF Writer ), beyond threats from customers of mass migration to another vendor's software.

Most of the students had already signed, so the mass murder would appear to be a mass suicide instead.

( Most of the universe's mass is not in the form of chemical elements — that is, " baryonic " matter — but is made up of dark matter and dark energy.

Most historical linguists ( Campbell 2001: 45 ) reject the use of mass comparison as a tool for establishing genealogical relationships between languages.

Most cell phones are equipped with internet access and capable of connecting to the web which itself a mass medium.

Most populations of the woolly mammoth in North America and Eurasia, as well as all the Columbian mammoths in North America, died out around the time of the last glacial retreat, as part of a mass extinction of megafauna in northern Eurasia and the Americas.

( Most of the elongated triangular continental mass of Zealandia is a subsurface plateau.

Most theories see the nation state as a 19th-century European phenomenon, facilitated by developments such as mass literacy and the early mass media.

Most recently, on 6 July 2009, the New Jersey Supreme Court had also designated litigation over Levaquin as a mass tort and has assigned it to an Atlantic County, N. J., judge.

Most of the takeoff mass of a rocket is normally propellant.

Most of Paine's arguments had long been available to the educated elite, but by presenting them in an engaging and irreverent style, he made deism appealing and accessible to a mass audience.

Most escapes were by individuals or small groups ; occasionally, there were mass escapes, such as with the Pearl incident.

Most Western countries experienced a large economic boom, due to the mass production of railroads and other more convenient methods of travel.

Most political scientists agree that the mass media have a profound impact on voting behavior.

Most serious mass driver designs use superconducting coils to achieve reasonable energetic efficiency ( often 50 % to 90 +%, depending on design ).

Most are defined in kilojoules per mole ( kJ mol < sup >− 1 </ sup >), but can also be measured in calories per mole, joules per mole or kilocalories per gram ( any combination of these units conforming to the energy per mass or amount guideline ).

Most mass transit systems move people in groups over scheduled routes.

Most humidity charts are given in g / kg or kg / kg, but any mass units may be used.
