Mass sufficiency

From this equation it can first be deduced that the successful synthesis of high polymers by step polymerisation (i.e., polymers exhibiting molecular mass sufficiently high to be useful for technological application) requires very high conversion levels. 

Note The first decimal of the m/z values of carbenium ions continuously rises with increasing m/z as a result of mass sufficiency of hydrogen (Chap. 3.3). Theoretically from C32H6s onwards m/z 449.5081), rounding of the m/z value causes a shift to the next integer m/z, and thus result in confiision due to the nitrogen rule. Therefore, integer m/z values should not be used above m/z 400 instead use of the decimal is recommended for LR-MS. 

A single kilogram of radioactive metallic plutonium-238 produces as much as 22 million kilowatt-hours of heat energy. Larger amounts of Pu-238 produce more heat. However, Pu-238 is not fissionable, and thus it cannot sustain a chain reaction. However, plutonium-239 is fissionable, and a 10-pound ball can reach a critical mass sufficient to sustain a fission chain reaction, resulting in an explosion, releasing the equivalent of over 20,000 tons of TNT. This 10-pound ball of Pu-239 is only about one-third the size of fissionable uranium-235 required to reach a critical mass. This makes plutonium-239 the preferred fissionable material for nuclear weapons and some nuclear reactors that produce electricity. 

The regeneration of specific tissues aided by synthetic materials has been shown to be dependent on the porosity and pore size of the supporting three-dimensional structure. A large surface area favors cell attachment and growth, whereas a large pore volume is required to accommodate and subsequently deliver a cell mass sufficient... 

Molasses answers an excellent purpose in very many cases. It must be added carefully, as an excess will make the pill-mass too fluid for manipulation. Gum Arabic in small quantities may be added where the molasses does not give the mass sufficient cohesion. It is frequently used alone for this purpose, either in the form of powder or of thick mucilage, but is objectionable, as the pills produced by its use are apt to become excessively hard on drying. 

In both cases pure concentrated acetic acid is formed. The temperature at which peracetic acid breaks down is somewhere in the vicinity of 100° C. (probably 80° to 100° C.) and the only safe way to proceed in the oxidation of acetaldehyde is, therefore, either to maintain the temperature at all points throughout the reacting masses sufficiently high to insure the decomposition of peracetic acid as rapidly as it is formed, or to secure the same result at a lower temperature by a mechanical agitation of the... 

The field equations of general relativity are rarely used without simplifying assumptions. The most common application treats of a mass, sufficiently distant from other masses, so as to move uniformly in a straight line. All applications of special relativity are of this type, in order to stay in Minkowski space-time. A body that moves inertially (or at rest) is thus assumed to have four-dimensionally straight world lines from which they deviate only under acceleration or rotation. The well-known Minkowski diagram of special relativity is a graphical representation of this assumption and therefore refers to a highly idealized situation. 

COAGULATION - Is the process whereby finely divided particles of turbidity and color, capable of remaining in suspension indefinitely, are combined by chemical means into masses sufficiently large to effect rapid settling. 

Mass accuracy-exact mass sufficient to exclude alternatives... 

Since the exact masses of individual atomic ions are known with high accuracy, the exact mass of an ion of a given empirical formula (a known combination of atoms) is also known with high accuracy by simple summation. In mass spectrometry, measurement of the exact mass of an ion is used to deduce information about the empirical formula (not the molecular formula) of the ion. If the total number of possible combinations is small, and the measurement of the exact mass sufficiently accurate, the measurement can be used to derive an ion empirical formula. The traditional exact mass measurement is usually limited to the more abundant ions observed in the mass spectrum, since higher mass resolution in sector instruments was achieved at the cost of lower ion signal.
