This work contains synthesis and characterization of new compounds [I-VIII], starting from compound [I] which was prepared through the reaction of chloroacetyl chloride with hydrazine hydrate and then cyclized the product with chloroacetic acid using phosphorous oxychloride to give 2,5-bis(chloromethyl)-1,3,4-oxadiazole compound [II], then the later compound [II] reacted with 4-hydroxy benzaldehyde to form compound [III]. The compound thiazolidine 2,4-dione [IV] was prepared from the reaction of chloroacetic acid with thiourea. Subsequently compound [III] reacted with compound [IV] to get [V] compound. Then the later compound was reacted with n-alkyl bromide (with several carbon atoms n= 4,5,6,8 ) to give compounds [VI]n. compound

Abstract:

               The aim of the research is to evaluate the practice of banking departments for strategic foresight represented by its dimensions (environmental scanning, future vision, scenarios, reconfiguration) and its relationship to the organizational brilliance represented by dimensions (brilliance of leadership, brilliance of service and innovation, brilliance of knowledge, brilliance of employees), as the research was applied in A number of private Iraqi commercial banks represented by (Baghdad, Iraqi Investment, Iraqi Middle East Investment, Commercial Gulf, Ashur International Investment, Al Mansour Investment, Via Iraq Invest

A numerical computation for determination transmission coefficient and resonant tunneling energies of multibarriers heterostructure has been investigated. Also, we have considered GaN/Al0.3Ga0.7N superlattice system to estimate the probability of resonance at specific energy values, which are less than the potential barrier height. The transmission coefficient is determined by using the transfer matrix method and accordingly the resonant energies are obtained from the T(E) relation. The effects of both well width and number of barriers (N) are observed and discussed. The numbers of resonant tunneling peaks are generally increasing and they become sharper with the increasing of N. The resonant tunneling levels are shifted inside the well by
