This is the all-important Q equation. What does it say It says that if we measure the kinetic energy of the emitted particle x and the angle at which it is emitted in a reaction, and we know the identities of the reactants and products of the reactions, we can determine the Q value of the reaction. In short, we can measure the energy release for any two-body reaction by measuring the properties of one of the products. If we calculate the Q value of a reaction using a mass table, then we can turn this equation around to calculate the energy of the emitted particle using the equation...

The measurement of diffusion rates as functions of various activities, in particular oxygen fugacity, is extremely important to clarifying the diffusion mechanisms and aid in extrapolation. The work of Ryerson et al. (1989) is the only geochemical example of such type of work. Questions of concern include under what conditions does the /02-dependence occur, and what does it tell us about the main mechanism of O2 transport (e.g. permeation versus diffusion, network versus molecular oxygen diffusion etc.).

A sensible question arises How do you know whether a spread duration for a fixed-rate bond is a spread based on the nominal spread, zero-volatility spread, or the OAS The simple answer is you do not know You must ask the broker/dealer or vendor of the analytical system. To add further to the confusion surrounding spread duration, consider the term OAS duration that is referred to by some market participants. What does it mean On the one hand, it could mean simply the spread duration that we just described. On the other hand, many market participants use the term OAS duration interchangeably with the term effective duration. Once again, the only way to know what OAS is measuring is to ask the broker/dealer or vendor.

Wanke et al. (2010) argue that the perception of logistics systems being complex is confirmed by several authors, but it is not always clear what does it mean. They defined complexity in logistics in terms of quantifiable scales and based on the notion of numerous actors or parts that are interconnected and can be captured by measures such as the company s gross revenue, its number of supphers, active customers, number of employees, number of employees involved in supply chain management, active stock keeping tmits (SKUs), number of distribution centers, orders processed and new product launches per year.

The points in Fig. V-12 come from three types of experimental measurements. Explain clearly what the data are and what is done with the data, in each case, to get the w-versus- plot. What does the agreement between the three types of measurement confirm Explain whether it confirms that is indeed the correct absolute interfacial (Krtential difference. 

Nernst, in his Theoretische Chemie, devoted a whole chapter to a critical examination of the rule of Thomsen and Berthelot, and he concluded that in many cases the heat of reaction certainly does correspond very closely with the maximum work, AT, which latter magnitude he took from van t Hoff as a measure of the chemical affinity. Whilst pointing out that it very often gives results wholly incompatible with experience, and cannot therefore be indiscriminately applied, Nernst showed that the rule nevertheless holds good in too many cases to be wholly false in an appropriate metaphor he claimed that it contains a genuine kernel of truth which has not yet been shelled from its enclosing hull. This labour of emancipation was partially effected in the newer work of the same author, Applications of Thermodynamics to Chemistry, 1907, which is an attempt to place the rule of Berthelot on a scientific basis, and to determine under what conditions its use is legitimate. He points out that the equation ... 

There is, then, the problem of determining for each discipline what it does in the way of diseovery and proof, what eriteria it uses for measuring the quality of its data, how strietly it can apply canons of evidence, and in general, of determining the route or pathway by whieh the discipline moves from its raw data through a longer or shorter proeess of interpretation to its conclusion .
