Most of the Teutonic Order's territory, however, including towns which had surrendered, remained intact.

Most important are Audax ( 904-926 ) and Bruningus ( 937-966 ), who moved the episcopal seat to the Castel Vecchio (" Old Castle "), where it remained until 1409.

Most of Provence remained strongly Catholic, with only one enclave of Protestants, the principality of Orange, Vaucluse, an enclave ruled by Prince William of the House of Orange-Nassau of the Netherlands, which was created in 1544 and was not incorporated into France until 1673.

Most of voters declared themselves contrary to the ban and the laws regarding commerce and ownership of weapons in the country remained unaltered.

Most moved to Canada after the Treaty of Canandaigua in 1794, some remained in New York, and some moved to Ohio, joining the Shawnee.

Most of the Noldor sailed back to Aman at the End of the First Age ; but some, like Galadriel ( daughter of Finarfin ) or Celebrimbor ( grandson of Fëanor ), refused the pardon of the Valar and remained in Middle-earth.

Most Indonesians lived in fear and uncertainty, particularly a significant proportion of the population who supported the Dutch or who remained under Dutch control.

Most of James's work has remained continuously in print since its first publication, and he continues to be a major figure in realist fiction, influencing generations of novelists.

Most of the v2 activities remained untouched in v3, but some significant changes in terminology were introduced in order to facilitate the expansion.

Most who remained in France aimed to defend and further French culture and thereby weaken the German hold on occupied France.

Most of these remained in their established immigrant communities, but by the second or third generation, many families were able to relocate to better housing in the suburbs after World War II.

Most of the area remained agricultural until the mid nineteenth century, the most notable building of the time being the ' Brockley Jack ' ( since rebuilt ), a large Victorian public house which today houses the Brockley Jack Theatre.

Most of the original pre-fabricated buildings remained in use for more than 80 years before a major renovation around the turn of the century.

Most were removed to Indian Territory in the 1830s, but some remained and became citizens of the state and United States.

Most acid soils are saturated with aluminium rather than hydrogen ions.

Most of the hydrogen and helium in the universe was produced primordially in the first few minutes of the Big Bang.

Most hydrogen is employed near its production site, with the two largest uses being fossil fuel processing ( e. g., hydrocracking ) and ammonia production, mostly for the fertilizer market.

Most scholars have agreed with the assessment made by Hans Bethe in 1952, which concluded that by the time Fuchs left the thermonuclear program — the summer of 1946 — there was too little known about the mechanism of the hydrogen bomb for his information to be of any necessary use to the Soviet Union ( the successful Teller-Ulam design was not discovered until 1951 ).

Most gases are heavy enough to be well pumped but it is difficult to pump hydrogen and helium efficiently.

Most liquid-phase engines have focused on rotating the fuel / fluid mixture at very high speeds, forcing the fuel to the outside due to centripetal force ( uranium is heavier than hydrogen ).

Most peptide bonds overwhelmingly adopt the trans isomer ( typically 99. 9 % under unstrained conditions ), chiefly because the amide hydrogen ( trans isomer ) offers less steric repulsion to the preceding atom than does the following atom ( cis isomer ).

Most oscillators, from a guitar string to a bell ( or even the hydrogen atom or a periodic variable star ) will naturally vibrate at a series of distinct frequencies known as normal modes.

Most species produce hydrogen sulfide, which can readily be detected by growing them on media containing ferrous sulfate, such as TSI.

Most used a neon-based gas mixture and counted in base-10, but faster types were based on argon, hydrogen, or other gases, and for timekeeping and similar applications a few base-12 types were available.

Most ionic hydrides exist as " binary " materials involving only two elements including hydrogen.

Most rocket engines use light-weight fuels ( liquid hydrogen, oxygen, or kerosene ) accelerated to super-sonic speeds.

Most high explosives contain carbon, hydrogen, nitrogen and oxygen atoms and thus comparing their relative abundances of isotopes can reveal the existence of a common origin.

Most emission nebulae are about 90 % hydrogen, with the remainder helium, oxygen, nitrogen, and other elements.

Most hypothetical constructions rely on the fact that hydrogen bombs can be made arbitrarily large assuming there are no concerns about delivering them to a target ( see Teller – Ulam design ) or that they can be " salted " with materials designed to create long-lasting and hazardous fallout ( e. g., a cobalt bomb ).

Most hydrogenations use gaseous hydrogen ( H < sub > 2 </ sub >), but some involve the alternative sources of hydrogen, not H < sub > 2 </ sub >: these processes are called transfer hydrogenations.

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 notable is the fact that this collision can help provide a view into what happened in the postulated beginning of the universe some 14 billion years ago, since shocked molecular hydrogen is likely to be present in the early universe.

Most of a star ’ s mass consists of light hydrogen and helium.

Most commonly, replenishers are used with hydrogen ; a filament made from a hydrogen-absorbing metal ( e. g. zirconium or titanium ) is present in the tube, and by controlling its temperature the ratio of absorbed and desorbed hydrogen is adjusted, resulting in controlling of the hydrogen pressure in the tube.

Most hydrogen atoms bound in water molecules have a single proton for a nucleus.
