E Structure

Once the basic performance of the design has been evaluated, changes can be made to improve the performance in other words, we optimize. These changes might involve the synthesis of alternative structures, i.e., structural optimization. Thus we simulate and...

In these examples B is a base. The first example is called a secondary isotope effect of the first kind, the next one is a secondary isotope effect of the second kind. The distinction between these is that in the first kind bonds to the isotopic atom have undergone spatial (i.e., structural) change. Halevi has reviewed secondary isotope effects on equilibria and rates.

A shallow stratigraphic test is a relatively shallow well drilled to provide information on the local geology, i.e. structure, facies, geochemistry, etc. Normally its immediate purpose is not exploration for oil or gas accumulations. 

This result can be simplified considerably by observing that, except for end effects, the number of transitions from X to Y along the polymer chain (i.e., structures like XY ) must equal the number of transitions from Y to X (i.e., structures like YX ). This requires that...

In recent years a number of new isoquinoline alkaloids of untypical structures, i.e., structures with open heterocyclic rings, have been isolated from natural sources. These bases were named secoisoquinoline alkaloids because they were believed to be produced in vivo from classic isoquinoline alkaloids as a result of various degradation processes causing oxidative cleavage of some bonds.
