and then the system (34) is of regular type (see [15, 29]).
For (a_{mathrm{sn}}^< a), the fold (F^) is of regular jump type and a large stable relaxation cycle exists.
From (3), we know that zeros and poles are Borel exceptions of f t ( t = 1, 2 ), and from [[23], Satz 13.4], we have that f t ( t = 1, 2 ) is of regular growth.
Since the paralic Agbada Formation is of regular alternation of sand shale interval, there is a greater possibility of the shale smear sealing the growth faults and creating the required hydrocarbon traps, though in some cases, they act as migration pathways for oil and gas.
The remaining n−1 layers on each side (top and bottom) of the primary layer, starting from immediate layer adjacent to it, alternate between being a layer that is of irregular hexagonal shape (which we call IH layer), and being a layer that is of regular hexagonal shape (which we call RH layer).
The endothermal peak of the PCM melting is of regular shape showing onset at 35 °C and maximum at 39 °C, which is somewhat above the melting temperature of pure n-eicosane, 36.2 °C.
