Interpretive definition

The concentration of the catalyst in the matrix is especially important for this catalysis. When the catalyst concentration exceeded ca. 0.05 mol dm-3 in a matrix, the activity decreased drastically. Although this result can not yet be interpreted definitively, it suggests that since the catalysis should be a bimolecular process, the low concentration of the complex catalyst is important so the two molecules of a H+-coordinated intermediate can find the best location for a cooperative H2 formation. [Pg.165]

We do not offer a definitive interpretation. A symbol by its very nature cannot be interpreted definitively, and it will evoke different associations and meanings in each person and in the same person at different times. To give but one example early in his analytic work, a man reported an energy-filled dream from his youth, and he referred to it often as he recalled the suffering of his childhood. Later in his analysis, he wrote about the way its meaning for him had changed ... [Pg.30]

The DOD system safety programs tend to be more standardized than those of some other agencies, primarily because MIL-STD-882B serves as a foundation for the effort. However, considerable variation in programs, concepts, interpretations, definitions, and approaches occurs, even within the DOD community. This variability is most pronounced in the attempts of contractors to interpret and conform to system safety requirements. [Pg.31]

An ontology can be defined as a definition of a common vocabulary for researchers who need to share information in a domain. It includes machine-interpretable definitions of basic concepts in the domain and the relations among them. An ontology necessarily includes a common vocabulary of terms and a specification of their meaning [16]. Without specification, the set of ontology concepts would be variously interpretable by different sets of users. With specification, different users (e.g., experts in different lifecycle phases) with different views on a single reality can be accommodated. [Pg.261]

In summary, exploration activities require the integration of different techniques and disciplines. Clear definition of survey objectives is needed. When planning and executing an exploration campaign the duration of data acquisition and interpretation has to be taken into account. [Pg.27]

We must now mention, that traditionally it is the custom, especially in chemo-metrics, for outliers to have a different definition, and even a different interpretation. Suppose that we have a fc-dimensional characteristic vector, i.e., k different molecular descriptors are used. If we imagine a fe-dimensional hyperspace, then the dataset objects will find different places. Some of them will tend to group together, while others will be allocated to more remote regions. One can by convention define a margin beyond which there starts the realm of strong outliers. "Moderate outliers stay near this margin. [Pg.213]

The unit vectors Ci, whose exact definition, meaning and interpretation depend on the particular application at hand, are called basis vectors and form the elements of a basis. They are particularly simple to work with because they are orthogonal. This means that... [Pg.521]

Definiteness. Adequate description or definiteness requites that the patent claims provide an outline of those elements which are integral to the appHcation s invention. In turn, the specification acts as a dictionary wherein the reader can interpret and understand the elements in the patent claims. Complementary to the requirement of definiteness is the requirement that the appHcation must disclose the entire invention. The appHcant cannot make a claim of right to the invention where essential elements of the invention are not disclosed in the patent. [Pg.34]

NMR data for 4-methyloxazole have been compared with those of 4-methylthiazole the data clearly show that the ring protons in each are shielded. In a comprehensive study of a range of oxazoles. Brown and Ghosh also reported NMR data but based a discussion of resonance stabilization on pK and UV spectral data (69JCS(B)270). The weak basicity of oxazole (pX a 0.8) relative to 1-methylimidazole (pK 7.44) and thiazole (pK 2.44) demonstrates that delocalization of the oxygen lone pair, which would have a base-strengthening effect on the nitrogen atom, is not extensive. It must be concluded that not only the experimental measurement but also the very definition of aromaticity in the azole series is as yet poorly quantified. Nevertheless, its importance in the interpretation of reactivity is enormous. [Pg.33]

The previous definitions can be interpreted in terms of ionic-species diffusivities and conductivities. The latter are easily measured and depend on temperature and composition. For example, the equivalent conductance A is commonly tabulated in chemistry handbooks as the limiting (infinite dilution) conductance and at standard concentrations, typically at 25°C. A = 1000 K/C = ) + ) = +... [Pg.599]

Maintenance is not a glamorous procedure however, its importance is second to none. Maintenance procedures are always controversial, since the definition of upkeep varies with the individual interpretation of each maintenance supervisor. The latitude of maintenance ranges from strict planning and execution, inspection and overhaul, accompanied by complete reports and accounting of costs, to the operation of machinery until some failure occurs, and then making the necessary repairs. [Pg.722]

To understand the possible benefits, we must first develop a working definition of pollution prevention. Although the term seems obvious, there are often wrong interpretations given to P2 practices. [Pg.350]

To use the volume effectively, the reader should first review the Glossary of Terms section immediately preceding the first chemical entry. This section contains precise definitions used for certain parameters where data have been obtained for each chemical. A review of these terms will help the reader interpret certain information. In addition, a list of abbreviations used throughout the volume is also provided in the front section of the handbook. [Pg.438]

Frequency with the dimensions of per unit time, ranges from zero to infinity and means the number of occurrences per time interval. Probability is dimensionless, ranges from zero to one, and has several definitions. The confusion between frequency and probability arises from the need to determine the probability that a given system will fail in a year. Such a calculation of probability explicitly considers the time interval and, hence, is frequency. However, considerable care must be used to ensure that calculations are dimensionally correct as well as obeying the appropriate algebra. Three interpretations of the meaning of probability are ... [Pg.39]

The relationships between the importance measures is based on the assumption that the systems are not reconfigured in response to a component outage. If this is done, the basic definition of the importance measure is still valid but there is not such a simple relationship. Disregarding this complication, some interpretations of the importances may be made. The Bimbaum Importance is the risk that results when the i-th system has failed (i.e., it is the A, term in Equation 2.8-9). Inspection Importance and RRWI are the risk due to accident sequences containing the i-th system. Fussell- Vesely Importance is similar except it is divided by the risk so may be interpreted as the fraction of the total risk that is in the sequences contains the Q-th system. The Risk Achievement Worth Ratio (RAWR) is the ratio of the risk with system 1 failed to the total risk and is necessarily greater than one. The Risk Achievement Worth Increment (RAWI) is the incremental risk increase if system 1 fails and the Risk Reduction Worth Ratio (RRWR) is the fraction by which the risk is reduced if system 1 were infallible. [Pg.64]

Life cycle assessment is defined by ISO 14040 as compilation and evalu ation of inputs, outputs and the potential environmental impacts of a product system throughout its life cycle. The ISO standards regulate the procedural aspects of LCA. They do not, however, provide all the information required for carrying out an LCA study. The main phases of LCA are goal and scope definition, inventory, impact assessment, and interpretation. The various applications of LCA are not regulated by the standard (Fig. 15.1). [Pg.1358]

In order to eharaeterize the dewetting kineties more quantitatively, the time dependenee of the average thiekness of the film and the deerease of adsorbed fraetion Fads(0 with time (Fig. 34) are monitored. The standard interpretation of the behavior of sueh quantities is in terms of power laws, ads(0 with some phenomenologieal exponents. From Fig. 34(a), where sueh power-law behavior is indeed observed, one finds that the exponent a is about 2/3 or 3/4 for small e and then deereases smoothly to a value very elose to zero at the eritieal value e k. —. 2 where the equilibrium adsorbed fraetion F s(l l) starts to be definitely nonzero. If, instead, one analyzes the time dependenee of — F ds(l l) observes a eollapse... [Pg.620]
