Translational number

Greece (Translation) Number 1437/89 Approval of the amendment of the article 44 of the Food Code in compliance with the directive nr. 88/388/EEC (Official Gazette of the Greek Republic, Athens, 17. September 1990, 2nd issue, edition Nr. 599). [Pg.764]

Small numbers and percentages are the enemies of data analysis. The two often go together because people translate numbers into percentages, and so can hide the fact that the original data came from a very small population. Thus a change in accident rate of 33% can sound impressive until it is realised that this is a decrease from 15 accidents to 10 in one year which may not be statistically significant. [Pg.233]

Translating number of rubs to a timed approach relied on the appearance of the skin during the procedure (like Hetter). It was clear that Obagi, using TCA (trichloroacetic acid) and Hetter, using the Heresy formulae, relied on... [Pg.73]

Although a diatomic molecule can produce only one vibration, this number increases with the number of atoms making up the molecule. For a molecule of N atoms, 3N-6 vibrations are possible. That corresponds to 3N degrees of freedom from which are subtracted 3 translational movements and 3 rotational movements for the overall molecule for which the energy is not quantified and corresponds to thermal energy. In reality, this number is most often reduced because of symmetry. Additionally, for a vibration to be active in the infrared, it must be accompanied by a variation in the molecule s dipole moment. [Pg.57]

The non-consen>ed variable (.t,0 is a broken symmetry variable, it is the instantaneous position of the Gibbs surface, and it is the translational synnnetry in z direction that is broken by the inlioinogeneity due to the liquid-vapour interface. In a more microscopic statistical mechanical approach 121, it is related to the number density fluctuation 3p(x,z,t) as... [Pg.727]

The apparatus consists of a tip-position controller, an electrochemical cell with tip, substrate, counter and reference electrodes, a bipotentiostat and a data-acquisition system. The microelectrode tip is held on a piezoelectric pusher, which is mounted on an inchwomi-translator-driven x-y-z tliree-axis stage. This assembly enables the positioning of the tip electrode above the substrate by movement of the inchwomi translator or by application of a high voltage to the pusher via an amplifier. The substrate is attached to the bottom of the electrochemical cell, which is mounted on a vibration-free table [, and ]. A number... [Pg.1941]

The frequency (number per second) of /transitions from all g. degenerate initial internal states and from the p. d E. initial external translational states is equal to tire reverse frequency from the g degenerate final internal states and the pyd final external translational states. The detailed balance relation between the forward and reverse frequencies is therefore... [Pg.2013]

The number of translational states per unit volume dR with directed energies E = (E, p) in the range [E, E +... [Pg.2013]

Check. The number of free particles with all momenta p in equilibrium with a gas bath of volume v at temperature T is the translational partition fiinction Z>. Since the fraction of particles with energy E is exp (-... [Pg.2014]

The length or dimension of the RDF code is independent of the number of atoms and the size of a molecule, unambiguous regarding the three-dimensional arrangement of the atoms, and invariant against translation and rotation of the entire molecule. [Pg.416]

It is possible (see, for example, J. Nichols, H. E. Taylor, P. Schmidt, and J. Simons, J. Chem. Phys. 92, 340 (1990) and references therein) to remove from H the zero eigenvalues that correspond to rotation and translation and to thereby produce a Hessian matrix whose eigenvalues correspond only to internal motions of the system. After doing so, the number of negative eigenvalues of H can be used to characterize the nature of the... [Pg.515]

Conservation of reaction units requires that the number of reaction units associated with the reactant A equal the number of reaction units associated with the reactant B. Translating the previous statement into mathematical form gives... [Pg.21]

Each bin is connected to a memory location in a computer so that each event can be stored additively over a period of time. All the totaled events are used to produce a histogram, which records ion event times versus the number of times any one event occurs (Figure 31.5).With a sufficiently large number of events, these histograms can be rounded to give peaks, representing ion m/z values (from the arrival times) and ion abundances (from the number of events). As noted above, for TOP instruments, ion arrival times translate into m/z values, and, therefore, the time and abundance chart becomes mathematically an m/z and abundance chart viz., a normal mass spectrum is produced. [Pg.223]

Two decimal numbers (17, 24) represented in binary bits in an x-register ((WlOOOl) and a y-register (0011000). Addition into the a-register gives OlOlOOl, which translates as 41 (decimal). [Pg.307]
