Ignorance definition

Chemists very successfully use many concepts in a more intuitive manner, although they generally tend not to define their concepts clearly (Uke the bond order), and to ignore definitions if they happen not to be convenient. 

For polyatomic molecules, theory based on the equipartition theorem allows one to calculate only limiting values for Cy by either completely ignoring all vibrational contributions or assuming that the vibrational contributions achieve their full classical value. For monatomic gases and all ordinary diatomic molecules (where the vibrational contribution is not important at room temperature and can be ignored), definite Cy values can be calculated. For a brief discussion of a more accurate calculation of C (vib), see Exp. 37. 

The set of possible data names can be restricted by a diction-aiy. which specifies which names can be used within a file to conform to the specified dictionary. Dictionaries can also be used to specify which data items will be processed by some software. In this case entries not defined by an appropriate dictionaiy will simply be ignored. Dictionaries arc defined in so-callcd dictionary definition language (DDL). Several commonly used dictionaries arc shown in Tabic 2-9. Two of them (GIF and mmCIF) arc discu.sscd below in greater detail. 

Pumping and heat exchange form part of a functional unit. Tn-process storage is ignored, but large storage requirements for raw materials, intermediates, or products are usually estimated separately. Sometimes there are difficiilties in the identification and definition of the functional units involved in a process. 

There are, however, a number of well-known systems in which heat effects definitely cannot be ignored. Examples include absorption of ammonia in water, dehumidification of air with concentrated H9SO4, absorption of HCl in water, and absorption of SO3 in H9SO4. Another interesting example is the absorption of acetone in water, in which the heat effec ts are mild but not neghgible. 

Violation Error/Failure A violation error occurs when an intended action is made which deliberately ignores known operational rules, restrictions, or procedures. However, this definition excludes actions that are deliberately intended to harm the system, which come within the category of sabotage. 

Cayley has advanced the computation of and to an impressive degree. The definition of ignoring the notion of root, is simpler than that of However, we will see that, from an analytical point of view, is easier to handle than can be derived... 

Thus, two interpretations based on two different concepts of the effect of temperature on dipole orientation have been put forward. The two views clash with each other on physical as well as chemical grounds. However, the view based on the correlation of Fig. 25 introduces chemical concepts that are absent in the other, which ignores some definite facts. For instance, although a value for dEa=0/dT is not available for Ga, the temperature coefficient of C is apparently small.905 Ga is universally recognized as a strongly hydrophilic metal. Therefore, according to the simple model of up-and-down dipoles, the effect of temperature should be major, which is in fact not the case. 

The importance of dilfusion in a tubular reactor is determined by a dimensionless parameter, SiAt/S = QIaLKuB ), which is the molecular diffusivity of component A scaled by the tube size and flow rate. If SiAtlB is small, then the elfects of dilfusion will be small, although the definition of small will depend on the specific reaction mechanism. Merrill and Hamrin studied the elfects of dilfusion on first-order reactions and concluded that molecular diffusion can be ignored in reactor design calculations if... 

Laboratory equipment is sometimes stolen. Most popular are smaller items of relatively high value, such as electronic balances. Permanent identification marks definitely discourage theft. One stolen microscope was quickly returned to its owner when it appeared on the used equipment market. It was easily identifiable because its owner had engraved marks not only on the body, but also on objectives and eye pieces. The thief, fortunately, had ignored them. 

Surprisingly little attention has been given hitherto to the definition of the laboratory. A space has to be specially adapted to deserve that title. It would be easy to assume that the two leading experimental sciences, physics and chemistry, have historically depended in a similar way on access to a laboratory. But while chemistry, through its alchemical ancestry with batteries of stills, had many fully fledged laboratories by the seventeenth century, physics was discovering the value of mathematics. Even experimental physics was content to make use of almost any indoor space, if not outdoors, ignoring the possible value of a laboratory. The development of the physics laboratory had to wait until the nineteenth century... 

When life is to be defined, it is necessary for the purposes of biogenesis research to limit the discussion to the simplest life forms. This type of reduction is necessary in order to be able to make a clear division between inanimate and animate objects. Even for reduced systems , the boundaries between the two become unclear, as shown by the example of viruses. A definition of minimal life makes it possible to ignore the complex properties of higher living organisms, such as consciousness, intelligence or ethics. 

The use of PIR compounds to study protein interactions is a significant advance over the use of standard homobifunctional crosslinkers. The unique design of the PIR reagent facilitates deconvolution of putative protein interaction complexes through a simplified mass spec analysis. The software can ignore all irrelevant peak data and just focus analysis on the two labeled peptide peaks, which accompany the reporter signal of appropriate mass. This greatly simplifies the bioinformatics of data analysis and provides definitive conformation of protein-protein crosslinks. 

Electrochemical interfaces are sometimes referred to as electrified interfaces, meaning that potential differences, charge densities, dipole moments, and electric currents occur. It is obviously important to have a precise definition of the electrostatic potential of a phase. There are two different concepts. The outer or Volta potential ij)a of the phase a is the work required to bring a unit point charge from infinity to a point just outside the surface of the phase. By just outside we mean a position very close to the surface, but so fax away that the image interaction with the phase can be ignored in practice, that means a distance of about 10 5 — 10 3 cm from the surface. Obviously, the outer potential i/ a U a measurable quantity. 

It is clear from the integration limits in Eq. (A.4) that the sequence of interactions between particles 1 and 2 must precede the interactions of the other types. Moreover, the expression (A.4) corresponds to the ensemble of contributions where the interactions between particles 1 and 3 are arbitrarily ordered with respect to interactions between particles 2 and 4 and it follows from the fact that the group (1,3) ignores the group (2,4) during the interval that extends from the initial instant to the instant rn. One can easily verify that this chronological ordering of the events is already contained in formula (A.3) (see the definition (61) of (2)2>(34))-...
