Introduction :
In this issue of Frontiers in Science and Engineering International Journal, four papers are edited, two of them are dealing with mathematics and applications while the other two are for organic chemistry and materials.
The first paper entitled “Derivation of new chemotaxis models by asymptotic” presents a new approach to derive macro-scale models in biology using appropriate developments of kinetic theory and statistical mechanics at the cellular scale.
In the second paper entitled “The structure of some 2-groups and the capitulation problem for certain biquadratic fields”, the capitulation problem for certain number fields K of degree 4 is studied and followed by the determination of the structures of some 2-groups as an application.
The third paper entitled “Synthesis and UV-Visible complexation study of 1-pyrazolylbenzimidazol-2-one polyether macrocyclic derivatives” deals with a new polyether macrocyclic of 1 pyrazolylbenzimidazol-2-ones 5-6 that have been synthesized by the reaction of dichloro(poly)ethylene glycol in phase transfer catalysis conditions. The structure of these compounds were also identified.
In the fouth paper entitled “Atomic relaxation studying in Ag and Cu systems with (100) and (110) orientation”, the atomic relaxation in copper and silver Substrates are thoroughly investigated.
