Here the transition state is approximated by the lowest crossing pomt on the seam intersecting the diabatic (non-interacting) potential energy surfaces of the reactant and product. The method was originally developed... 

To continue, we assume the following situation We concentrate on an x-y plane, which is chosen to be perpendicular to the seam. In this way, the pseudomagnetic field is guaranteed to be perpendicular to the plane and will have a nonzero component in the z direction only. In addition, we locate the origin at the point of the singularity, that is, at the crossing point between the plane and the seam. With these definitions the pseudomagnetic field is assumed to be of the form [113]. 

Seams. As a defect, a seam is distinct from the seam resulting from a welding process. Seam defects can be found in nonwelded (seamless) tubes. They can originate from blow holes or nonmetallic inclusions in the ingot and are caused by crevices that have been closed by some rolling process but remain unfused. At times, they will appear in a spiral pattern in tubes. Seams can be very tight and appear as hairlines on the surface. They can cause failure when the component is pressurized. 

The raphe nuclei are a cluster of nuclei found in the brainstem, where they are located in the medial portion of the formatio reticularis, the raphe. (The raphe is the junction of the left and right brainstem hemisphere, hence the name raphe=seam). Serotonergic nerve cells in the CNS originate from the raphe nuclei, i.e., their rostral portion, and because of their wide-ranging projections appear to supply serotonin (5HT) to the rest of the brain.

Table VI shows the analysis of the coals used in the combustion studies for mercury. P-3 is a Tebo and Weir seam mixture from Henry County, Missouri while DRB-E and MR are both Pittsburgh seam coals originating in Washington County, Pennsylvania. Table VII presents the results obtained with the 100-gram-per-hour combustor, and Table VIII presents the results obtained with the 500-pound-per-hour combustor.

In the longwalt system, which originated in Europe, two parallel entries arc excavated from the main mine entry directly into the coal seam. The parallel entries, which may he as much as 750 feet (365 meters) apart or more, arc then joined together at their far end by a crosscut. The coal face that is furmed at the crosscut is called the longwall."...
