The synthesis and characterisation of SFCA-I compounds has been performed. is one the key bonding phases in iron ore sinter, influencing physical properties such as strength, reducibility, strength degradation during reduction. results reported herein extend understanding solid solution limits phase, with single-phase materials containing 2.71, 3.23 3.73 mass% Al2O3. These contain less Al2O3 th...
let h be a separable hilbert space and let b be the set of bessel sequences in h. by using several interesting results in operator theory we study some topological properties of frames and riesz bases by constructing a banach space structure on b. the convergence of a sequence of elements in b is de_ned and we determine whether important properties of the sequence is preserved under the con...
