    Notes: Abstract In this note we characterize the compact and weakly compact weighted composition operatorsW π,ϕ on certain weighted locally convex spacesCV o(X, E) of vector-valued continuous functions induced by self maps ϕ ofX and the operator-valued mappings π ∶X→B(E).

    Notes: Summary A comparison among various forms of half-diallel analysis was made. The different half-diallel techniques used were: Griffing's model I, method 2 and 4, Morley-Jones' model; Walters and Morton's model, and Gardner and Eberhart's model. All these methods of diallel analysis were found to be interrelated. However, as the Gardner and Eberhart's model partitioned heterosis into different components as well as gave information about combining ability, this method had certainly some advantages over the others. The results further indicated the possibility of dominance variance being confounded with the additive variance of general combining ability.

    Notes: Abstract Pentaphyllous mutants in black gram were isolated in M2 generation of a segregating family, irradiated at 20kR. The genetic nature of mutants was tested by hybridizing with controls, and chi-square tests applied to the F2 population, proved it to be a monogenic recessive. The pentaphyllous mutant had a greater number of pods and leaves per plant and larger and more root nodules. It also showed improved nutritional value with increased seed protein percentage and no increase in TIA (trypsin inhibitor activity).

    Notes: This paper presents and discusses an Arnoldi-based eigensolution technique for evaluating the complex natural frequencies and mode shapes from frequency dependent quadratic eigenproblems associated with vibration analysis of damped structures. The new solution technique is used in conjunction with a mixed finite element modelling procedure which utilizes both the polynomial and frequency dependent displacement fields in formulating the system matrices. This modelling provides the ability to represent a frequency dependent damping matrix in vibration analysis of skeletal systems.The eigensolution methodology presented here is based upon the ability to evaluate a specific set of parametrized curves for the non-linear eigenvalue problem at given values of the parameter. Numerical examples illustrate that this method, used in conjunction with a secant interpolation, accurately evaluates the complex natural frequencies and modes of the quadratic non-linear eigenproblem and verifies that the new eigensolution technique coupled with the mixed finite element modelling procedure is more accurate than the conventional finite element models.
