Some groupings of natural numbers, when operated upon by the ordinary processes of arithmetic, reveal rather remarkable patterns, affording pleasant pastimes.
Thus, the arrangement of the whorls on a pinecone or pineapple, of petals on a sunflower, and of branches from some stems follows a sequence of Fibonacci numbers or the series of fractions Some groupings of natural numbers, when operated upon by the ordinary processes of arithmetic, reveal rather remarkable patterns, affording pleasant pastimes.
The daily mortality data from the NHDSS has some groupings of deaths on the 15th day of the month.
Cumulative exposures were calculated: a) generically combining all sectors, b) within the eight major sectors, and c) for some additional groupings of special interest, some of which were derived from preliminary observations such as in food manufacturing or automotive plastics.
Partial confidence is provided by the internal validation described in the above section, which indicates the set was well-constructed, and also by some natural groupings of metabolites associated with the detected principal components.
The researchers claim some groupings are reminiscent of dividing bacteria, and argue that their textured surface, the presence of lacy material resembling the mineralized biofilm produced by bacteria, and an occasional fibril-like filament also suggest "possible bacteria in Nakhla".
Some groupings feature images of one person taken by another, often in the same setting, providing especially intimate glimpses of relationships.
The population structure of N. meningitidis is effectively panmictic as a result of frequent horizontal genetic exchange (23 ), but that of some groupings, such as epidemic serogroup A meningococci, is largely clonal (24 ).
That is true of some groupings, such as the Ultras Nahdawy, which is not associated with a club and opposes Mr Sisi.
Example 1 below serves to illustrate some of these groupings of resources (mechanisms or 'strategies'), and the challenges which face the analyst attempting to account for the evaluative stance invoked in any one section of a longer piece.
In some specific habitats sparse groupings of continental halophytes (plants growing in saline soils) of "arctic takkyrs", zoochoric (plants with seeds dispersed by animals) groupings of annual-biennial "ruderals" and, finally, sparse xeric-psammophytic (plants adapted to dry, sandy soils) vegetation of "sand seas" occurred.
