Idea introduction solving

Both of these problems can be solved by the introduction of a periodic box I can explain this idea by Figure 2.4, which shows a much smaller two-dimensional box than the one discussed above. 

In Chapter 2, I gave you a brief introduction to molecular dynamics. The idea is quite simple we study the time evolution of our system according to classical mechanics. To do this, we calculate the force on each particle (by differentiating the potential) and then numerically solve Newton s second law... 

A very elegant solution to solve this problem is the introduction of either a permanent or a temporary phase boundary between the molecular catalyst and the product phase. The basic principle of multiphase catalysis has already found implementation on an industrial scale in the Shell higher olefin process (SHOP) and the Ruhrchemie/Rhdne-Poulenc propene hydroformylation process. Over the years, the idea of phase-separable catalysis has inspired many chemists to design new families of ligands and to develop new separation... 

The effects of guiding principles appear to depend heavily on the extent to which they fit in with the perceptions, ideas and interests of the particular involved parties (resonance and connectivity). In addition, they must meet the contributors capacities for action. A vital requirement for effect is also the relation of the particular corporate form, the branch of industry or the type of market and the potential to contribute in the solving of relevant problems. This also includes formulating the guiding principle at the right time (crisis relation, product cycle). A top-down introduction is also possible and is often necessary in some cases. 

The present article, which deals exclusively with electron diffraction in gases, does not pretend to give a complete survey or review of the field. The authors intention is, by a rather arbitrary choice of examples, mainly taken from the work done in Norway, to try to give an idea of what kind of problems we can hope to solve by the electron diffraction method. This, we hope, should be of greater value for those interested in the field of molecular structure than a more detailed theoretical introduction or a comprehensive review of all structure results obtained by electron diffraction during the last few years. 

In this introduction, I have tried to summarize some of the existing problems in membrane biogenesis and to relate the various topics that are discussed by the other authors. I hope that the different experimental approaches represented here will stimulate others in their quest to solve this important problem in biology and that the reader will gain as much pleasure as I did in learning about the new developments in the field. Finally, to paraphrase an oft used statement in fictional works—while the ideas expressed in this chapter may not necessarily be shared by the other contributors, since I had the prerogative of seeing their manuscripts first, any similarities in such views and ideas are not purely accidental.
