Migration origin, definition

If evaporation velocity is equal to the electrophoretic velocity but opposite in direction, the result of the interaction is the immobilization of the migrating ion on a definite point of the strip. If we consider the diagram, it is easy to understand why a particle must find its restpoint N independent of the actual spot of the paper where it was originally applied. This phenomenon explains the experiment of Fig. 4. 

It is important to preserve or translate as much of the original form and format of the data as possible, and that includes metadata. A database can contain a tremendous amount of metadata, such as audit trail information, electronic signatures, relationships between database tables, definition of field characteristics, etc. It is necessary to consider this metadata as part of the data set failure to do so could inhibit searchability and reporting after migration, make modification of old records problematic, or possibly even result in loss of the integrity of the records. Validation tasks associated with data migration must be geared to demonstrate that neither of these circumstances prevails. 

More generally, isomerization-hydroformylation can be defined as a process where the net 1,2-addition of H-CHO takes place away from the original olefin. This definition includes not only the particular isomerization in favor of the terminal olefin but also other migrations of the C=C double bond and subsequent hydroformylations.
