Most satellites have simple reliable chemical thrusters ( often monopropellant rockets ) or resistojet rockets for orbital station-keeping and some use momentum wheels for attitude control.

Most ores are a chemical compound of the metal with other elements, such as oxygen ( as an oxide ), sulfur ( as a sulfide ) or carbon and oxygen together ( as a carbonate ).

Most of this plasticity occurs at the neurochemical level ; dopamine transport systems are slowed, allowing dopamine to linger for longer periods of time in the chemical synapses in the striatum.

Most commonly associated with radiological or chemical materials, dirty bombs seek to kill or injure and then to deny access to a contaminated area until a thorough clean-up can be accomplished.

Most satellites have simple reliable chemical thrusters ( often monopropellant rockets ) or resistojet rockets for orbital station-keeping and some use momentum wheels for attitude control.

Most chelicerates rely on modified bristles for touch and for information about vibrations, air currents, and chemical changes in their environment.

Most Culture individuals opt to have drug glands that allow for hormonal levels and other chemical secretions to be consciously monitored, released and controlled.

Most industrial complexes are scattered throughout the city, however, the ' Zachem ' chemical works deserves attention, covering tens of square kilometers in the south-east of the city, the remnants of the German explosives factory built in World War II occupy an area which has its own rail lines, internal communication, housing, and large forested area.

Most LDPE, MDPE and HDPE grades have excellent chemical resistance, meaning that it is not attacked by strong acids or strong bases.

Most cast irons have a chemical composition of 2. 5 to 4. 0 % carbon, 1 to 3 % silicon, and the remainder is iron.

" Most autotrophs capture the suns energy in chlorophyll, but some autotrophs ( the chemolithotrophs ) obtain energy by the chemical oxidation of inorganic compounds and can grow in dark environments, such as the sulfur bacterium Thiobacillus, which lives in hot sulfur springs.

Most of the fat must be trimmed off prior to drying the meat, as fat does not dry, thus creating the potential for spoilage as the fat becomes rancid ( modern vacuum packing and chemical preservatives have served to help prevent these risks ).

Most spacecraft have some variety of rocket engine, and thus most research efforts focus on some variety of rocket propulsion, such as chemical, nuclear or electric.

Most force fields in chemistry are empirical and consist of a summation of bonded forces associated with chemical bonds, bond angles, and bond dihedrals, and non-bonded forces associated with van der Waals forces and electrostatic charge.

Most classical force fields implicitly include the effect of polarizability, e. g. by scaling up the partial charges obtained from quantum chemical calculations.

Most target bacterial functions or growth processes.

Most traditional pharmaceutical drugs are relatively small molecules that bind to particular molecular targets and either activate or deactivate biological processes.

Most carbonylation processes require metal catalysts, examples include the Monsanto acetic acid process and hydroformylation.

Most modern CVD processes are either LPCVD or UHVCVD.

Most recoveries are rapid, with all of the processes being done in several stages to avoid extensive deterioration of the peptide structure.

Most knitters probably aren ’ t even aware of the many processes that their fingers perform in the making of a single stitch.

Most early processes in Europe and Africa involved smelting iron ore in a bloomery, where the temperature is kept low enough so that the iron does not melt.

Most often other processes occurring in plants and animals keep gametic isolation and species distinction.

Most noise processes will have a white spectrum, at least over the bandwidth of interest, identical to that of thermal noise.

Most stable isotopes in the earth are believed to have been formed in processes of nucleosynthesis, either in the ' Big Bang ', or in generations of stars that preceded the formation of the solar system.

Most of that ( cognitive ) research on unconscious processes has been done in the mainstream, academic tradition of the information processing paradigm.

Most schists have been derived from clays and muds which have passed through a series of metamorphic processes involving the production of shales, slates and phyllites as intermediate steps.

Most reviving and repairing processes of the body are believed to happen during these two stages.

Most modern evolutionary biologists accept that the idea is consistent with many processes in evolution.

Most other Polish cities have suffered similarly, but the processes in Białystok, have had a particularly intense course.

Most scientists and conservationists agree that no place on earth is completely untouched by humanity, either due to past occupation by indigenous people, or through global processes such as climate change.

Most polyploids display heterosis relative to their parental species, and may display novel variation or morphologies that may contribute to the processes of speciation and eco-niche exploitation.

Most flintlocks were produced at a time before modern manufacturing processes became common.

Most address one specific set of functionality ; for instance, some allow the processes to be mapped ( see Business Process Mapping ) and documented ( such as Visio ); others allow for simulations to take place ( such as ARIS ).

Most vocal pedagogists believe in coordinating these processes by ( 1 ) establishing good vocal habits in the most comfortable tessitura of the voice, and then ( 2 ) slowly expanding the range.

Most models include software to diagnose a wide range of variables for comparison with observations or study of processes within the atmosphere.
