Numbers exploding series

When a combustible substance is mixed with air, the mixture will explode only when it is neither too rich nor too lean. The lower explosion limit (LEL) is the minimum volume percent of the substance in air with flammability, which is separated from the upper explosion limit (UEL) by the explosive concentration range. The tabulations in handbooks are based on experimental data, and sometimes derived from estimation methods based on the elemental composition of the fuel as CmEtxOy. Figure 6.11 shows the LEL for the series of normal paraffins and of 1-alcohols versus the number of carbon atoms. There are two ways to plot the results, which show that, for paraffins, the volume percent shows a steeply declining trend, but the weight percent shows a mildly increasing trend. One may conclude that a smaller volume percent of higher paraffin... 

Pressure within stars can increase to the point where sub-atomic particles fuse to form 2H, 3He, 4He, and 5He. The a-particle is the most stable of these units and becomes formed in sufficient excess to add progressively to each of four starting units to produce nuclides in four series of mass number An, 4n 1, An — 2, as observed [21]. Under these conditions the protonmeutron ratio for each series approaches unity with increasing mass number. At a certain age, a star of such magnitude explodes as a supernova to release the synthesized material into low-pressure environments in which a phase transition ensues. This transition consists of an inversion of energy levels... 

The candles were then eonnct ted in a series and attaclied to a blasting machine (see Fig. 16), The number of candk s that may be fired electrically is limited only by the capacity of the exploder or blasting niai hiiic used.
