Item Multiplicity of Positive Solutions of a Class of Ordinary Differential Equations With Nonlinear Boundary Conditions(Addis Ababa University, 2014-03-03) Kebede, Tesfahun; Abdi, Tadesse (PhD)In this paper we study the multiplicity solution of the boundary value problem u 00 + a(t)u 0 + f(u) = 0; B1(u(0)) u 0 (0) = 0; B2(u(b)) + u 0 (b) = 0; where 0 < t < b < 1, B1 and B2 2 C1[0;1); a 2 C[0;1) with a 0 on [0;1) and f 2 C[0;1) \ C1(0;1) satisfy suitable conditions. iiiItem Reactivities of Dilithium and Disodium Tetrai Sopropoxon Ickelates(II)with Carbondioxide and Some other –Acidic Ligands(Addis Ababa, 1989) Kebede, Tesfahun; Kalies, W.The reaction of the noval alkoxide of nicel (II). Lizni(oipr4.3THF and Na2Ni(oipr)4.2THF wthe co2 gave the first alkyl carbonate complexes of NI(II).vi li2ni(o2coipr)4.2THF and Na2 Ni(o2coipr)4.2THF.
