Three novel complexes of Cu(II), Co(II) and Zn(II) using a macrocyclic ligand derived by the condensation of diethylphthalate and benzidine have been designed,synthesized and characterized by UV-Vis.,IR,Mass and Elemental analyses data in order to find out their antifungal activities. The stoichiometry of the complexes has been found to be 1 : 1 (Metal : Ligand). The analytical data indicate that the complexes exhibit square-planar geometry. The antifungal activity of the macrocyclic ligand and its metal complexes has been screened in vitro against fungi such as Aspergillus niger, A. flavus, Trichoderma harizanum, T. viridae and Rhizoctonia solani.

In Vehicular Adhoc Network (VANET), the typical topology variations produced by the highly mobile nature of vehicle poses major issues in data transmission. The mobility and location based data dissemination techniques could satisfy the requirements of emergency message (EM) dissemination. It faces several issues in highway as well as urban roadways like minimum latency, highly secure, and scalable, which needs to be resolved. Generally, broadcasting protocols for VANET make use of beacon signals, which are distributed amongst the vehicles to attain information about the neighboring vehicles. With this motivation, this paper presents an energy aware cluster based routing protocol for the critical message dissemination (EAC-RPCMD) technique for VANET. The goal of the EAC-RPCMD technique aims to disseminate the EMs in the cluster based VANET environment. The EAC-RPCMD technique primarily designs an equilibrium optimizer based clustering (EOC) technique for the organization of vehicles into clusters. Besides, the manta ray foraging optimization (MRFO) algorithm based route selection (RS) technique, named MRFO-RS technique for optimal choice of routes to destination. Moreover, the EM dissemination scheme is also employed in the VANET. The performance validation of the EAC-RPCMD technique takes place and the results are inspected under several aspects.
