Culture and Identity in African and Caribbean Theatre
What connects Africa and the Caribbean is trans-Atlantic slavery which transported numerous sons and daughters of Africa to the plantations of the New World in the service of Western European capitalism. Because of this shared experience of trans-Atlantic slavery and European colonialism, issues of culture and identity are major concerns for African and Caribbean playwrights. Slavery and colonialism had involved systematic acts of cultural denigration, de-humanisation and loss of freedom, which left imprints on the collective psyches of the colonised Africans and enslaved peoples of African descent in the Caribbean. Both experiences brought intense cultural and psychic dislocations which still impact in various ways on the lives of Africans and peoples of African descent around the world.
African and Caribbean playwrights try to help their peoples regain their dignities by affirming their cultures, histories and identities. The book focuses on the similarities and differences between Caribbean theatre and the theatre of sub-Saharan Africa, showing how identities and cultures are negotiated and affirmed in each case
Susceptibility of selected commercial yeasts to autolysis for yeast extract production
A journal article on susceptibility of selected commercial yeasts to autolysis.Ten yeasts comprising nine Saccharomyces cerevisiae and one S.carlsbergensis were assessed for their susceptibility to autolysis for yeast extract production. The work was done in the period April to June,
2000. Each strain was autolysed in distilled water (pH 6.5) at 45°C for 6 hours and dry weight losses, release of proteins into the medium and pH monitored. Dry weight losses appeared to be the most discriminatory evidence of autolysis. Saccharomyces cerevisiae Y1045 and Y58 showed 25.0 percent and 23.9 percent dry weight losses respectively; the other strains autolysed less rapidly. Lactobacillus bulgaricusgrew comparably well in a basal medium supplemented with 5 percent (v/v) of S. cerevisiae Y1045 autolyzate, and in the same basal medium supplemented with 0.5 percent (w/v) commercial yeast extract. The study showed that S. cerevisiae Y1045 has the potential for use in yeast extract production
On iterative techniques for numerical solutions of linear and nonlinear differential equations
This paper presents Differential Transformation Method (DTM) and Picard’s Iterative Method (PIM) as computational techniques in solving linear and nonlinear differential equations. For numerical analysis of the methods, three examples are considered. The results obtained are compared with their corresponding exact solutions. A link between successive terms of the solutions using the two methods is noted. The DTM is very effective and reliable in obtaining approximate solutions. The PIM requires the satisfaction of Lipschitz continuity condition; though, its results also converge rapidly to the exact solutions
The Kumaraswamy-Power Distribution: A Generalization of the Power Distribution
We introduce a generalization referred to as the Kumaraswamy Power distribution. The proposed model serves as a generalization of the two-parameter Power distribution using the Kumaraswamy Generalized family of distributions. We investigate some of its statistical properties; the Generalized Power distribution, Exponentiated Power distribution and the Power distribution are found to be sub-models of the proposed distribution. The method of maximum likelihood estimation is proposed in estimating the parameters of the model
Correspondence Analysis for the Trend of Human African Trypanosomiasis
The aim of this research work is to give a graphical picture of the declining trend of the Human African
Trypanosomiasis (T.b. gambiense) in 12 selected endemic countries (based on 10 years data) via the application of
correspondence analysis. Grouping the countries into three regions affects the model but reveals that the disease is
most endemic in Central Africa but least in West Africa. Hence, we therefore recommend that efforts must be
intensified by the countries in the Central Africa to reduce the menace of the disease since graphically; there have
been reported cases mostly in this region for the past 10 year
Irreversibility Analysis of a Radiative MHD Poiseuille Flow through Porous Medium with Slip Condition
In this article, irreversibility analysis of thermal
radiation with slip condition on MHD Poiseuille flow through
porous medium is investigated. The upper and lower walls are
kept constant with the same temperature. The radiative heat
flux in the energy equation is assumed to follow Roseland
approximation. Semi-analytical solutions of the non-linear
boundary value problems obtained from the governing
equations is constructed using Adomian decomposition method,
and the effects of some fluid parameters on fluid motion,
temperature, entropy generation and Bejan number are
presented
Comparison Homotopy Perturbation and Adomian Decomposition Techniques for Parabolic Equations
This paper compares homotopy perturbation and Adomian decomposition techniques for the solution of parabolic equations. Some examples are considered to illustrate the
techniques. The results reveal that the two techniques gave
closed form of solution and as such considered most suitable for solving heat flow problems
Approximate Solution of Multipoint Boundary Value Problems
This study applies the Differential Transform Method (DIM) to obtain the approximate solution of
multipoint bmmdary value problems. Two examples are solved to illustrate the efficiency of the method.
Comparison with the solution obtained by Adomian Decomposition Method revealed that the DIM is an
excellent method for this type of problem
