Let p i ( n ) denote the number of the C ∞ -words of form w ̃ x w with length 2 n + i and gap i , where i is the length of word x . In this paper, we prove the following result: p i ( n ) = 6 for all n ≥ 1 and i = 2 , 3 , 4 . Moreover, we provid...
Donor AtomsWater pollution due to gold mining activity is increasingly worrying. One way to selectively mitigate it is through the use of complexing agents such as calixarenes, which selectively functionalized with soft donor atoms such as sulphur, can selectively remove this pollutant, for the ...
