“…So far in the literature, much attention has been drawn to the boundedness of solutions of ordinary scalar and vector nonlinear differential equations of third order. The book of Reissig et al [1], the papers by Abou-El-Ela [2], Afuwape [3] [4], Chukwu [5], Ezeilo [6], Ezeilo and Tejumola [7], Meng [8], Omeike [9], Omeike and Afuwape [10], Tiryaki [11], Tunc [12] [13], Tunc and Ates [14], Tunc and Mohammed [15] and the references cited therein have comprehensive treatment of the subject. Throughout the results present in the book of Reissig et al [1] and the papers mentioned above, Lyapunov's second (direct) method has been used as a basic tool to verify the results established in these works.…”
