Analytical reasoning

The reaction was also chosen for analytical reasons as the pyrazole ring is a good UV chromophore, facilitating analysis [20]. 

Using analytical reasoning what already exists can be deduced. Nothing new comes from it we only discover or unveil the mysteries and secrets of the world in which we live. That was the precise meaning of science according to the ancient... 

In the same way that syllogisms and theorems are the essence of analytical reasoning, the "heuristic principles" are the essence of synthetical reasoning. 

As illustrated above, analytical reasoning dominates current clinical pharmacology in that many efforts are directed at isolating and understanding the various factors that influence clinical effects. This is indeed the analytical phase outlined above, the indispensable phase of data gathering. But the objective is the prediction of clinical effects from results obtained with experimental model systems, and to this end a synthetic phase is necessary. 

No, but B might have, said C loftily, and it would have given him a good example of binocular vision, for it s where the intuitive, geometrical viewpoint needs to be checked by rigorous, analytical reasoning. But he evidently doesn t need the support of a pure mathematician. ... 

Fig. 11. Plot of initial cation transport rates for various carrier/alkali picrate pairs versus equilibrium extraction constants log Ke the points are experimental data, the curve is calculated [6.1, 6.4,6.17]. For analytical reasons the Ke values were determined in conditions different from those of the transport experiments the carriers are cryptands (for [2.2.C5] and [2.1.C5] see structures in [6.1]) dibenzo-18-crown-6, DB18-6 and valinomycin, VAL picrate, P.

Lumping constituents is clearly necessary when the reactant mixture is of such a complexity that it can only be characterized, for practical (e.g. analytical) reasons, by global properties that is notably the case for the pyrolysis of gas oils and crude oils. Examples of lumped constituent models can be found in refs. 35 and 36. In what follows, a few typical models will be briefly described, to bring to light the underlying principles of model building. 

Once the composition of middle salts was elucidated, the next step in analytic reasoning pointed to the composition of acids. Homberg had been working on an exact, quantitative determination of acids in their reactions with alkalis since 1695. Now he offered a principalist conjecture that acids might be composed of a common pure acid and a variety of sulphurous matters which differentiated them as well as conferring activity on them. Depending on the kind of sulphurous matters they contained, therefore, acids could be divided into three classes. The... 

The longer the pH range over which o° A is measured, the better It is for subsequent Interpretation and characterization. However, this range Is limited by experimental constraints. One is that at very low and very high pH it becomes increasingly difficult to determine changes in relation between the (dominant) amount in solution and measured cell potential is semilogarithmlc, i.e. the accuracy drops by a factor of 10 for each unit of pH, pAg, etc., at the lower and... 

Micro-bore capability often necessary for analytical reasons. 

Certain characteristics in the biotransformation of drugs make it difficult to evaluate the bioequivalence of such drugs. For example, for drugs that are stereoisomers with a different rate of biotransformation and a different pharmacodynamic response, the measurement of independent isomers may be difficult for analytical reasons.
