Polyazanes (i.e., higher nuclearity homologues of hydrazines) with increasing numbers bound nitrogen atoms (from 3 to 5), including the first pentazane ever described, were prepared by addition lower-order polyazanes diazo reagents. A structure was obtained. It shown that polynitrogen chains adopt a helical conformation. DFT modeling shows arrangement persists in solution. Although are all redu...

Asymptotic expansions for U-statistics and V-statistics with degenerate kernels are investigated, respectively, the remainder term O(n1−p/2), some p≥4, is shown in both cases. From results, it obtained that asymptotic Crame´r–von Mises statistics of uniform distribution U(0,1) hold On1−p/2 any p≥4. The scheme proof based on three steps. first one almost sure convergence a Fourier series expansi...

An efficient procedure is presented for the evaluation of solid oxide fuel cell (SOFC) anode microstructure triple phase boundary length (TPBL). Triple phase boundary- the one that is common between three phases of the microstructure- has a great influence on the overall efficiency of SOFC because all electrochemical reactions of anode take place in its vicinity. Therefore, evaluation of TP...

Evolution of languages has always been of interest to linguists.  In this paper we study  the natural progress of the syllable structure from Old  Persian  (O.P)  to Middle Persian (Mi.P) and up to the Modern Persian (Mo.P). For this purpose all the words containing consonant sequences are collected from specific sources of each  of these  languages,  and then  analysed  according to the syllab...
