5-Methyl-3,3-bis­(4-methyl­piperazin-1-yl)-1-[2-(4-methyl­piperazin-1-yl)eth­yl]indolin-2-one

In the title compound, C26H43N7O, each piperazine ring adopts a chair conformation. Two 1-methyl­piperazine rings bond to one Csp 3 of the pyrrole ring via the piperazine N atoms, while the third one links to the N atom of the indolin-2-one unit through a flexible ethyl group with an almost syn conformation. In the crystal, mol­ecules are connected through methyl­ene–carbonyl C—H⋯O inter­actions into an infinite chain along the c axis. The almost parallel arrays are stacked, forming a three-dimensional framework

Chaos and bifurcations in chaotic maps with parameter q: Numerical and analytical studies

In this paper, a class of chaotic maps with parameter q are introduced and bifurcations and chaos in proposed maps are numerical and analytical studied. Euler method is employed to get the continuous systems corresponding to chaotic maps and the fractional styles in Caputo's definition. Based on that, we finally infer a class of chaotic maps with the Adams–Bashforth–Moulton predictor-corrector method. In the simulation and analysis, we discuss the Logistic map with q and Hénon map with q, observe the route from period to chaos and do tests to analyze properties of maps with parameter q

Studentsa Ratings of School Climate and School Belonging for Understanding Their Effects and Relationship of Junior High Schools in Taiwan

This study was to explore junior high students perception of school climate and school belonging The main purposes of the present study were to test the relationships between school climate and school belonging How s the correlation between the two variables Which one has better effects on the other Three hundred and twenty-eight junior high students in Taiwan were selected to inclusion in the investigation A statistically significant relationship between school climate and school belonging was found From the construction analyses we found that the path coefficients of Model 1 and Model 2 are the same The outcomes meant that school climate had significant effects on school belonging and school belonging also had significant effects on school climate The results of the study can offer the relative schools for evaluating school effects and school improvemen
