Structure des algèbres de Bernstein
M. OUATTARA
The theory of Bernstein's algebras is revisited. Many results concerning the structure of Bernstein algebras (ideals, nilpotency and so on) are stated. For Bernstein-Jordan algebras, we give a definitive formulation of the theorem which characterizes them. Finally, we emphasize the importance of the invariant L (this ideal doesn't depend on th(...)

Dupliquée d'une algèbre et le théorème de whitehead
M. OUATTARA
The aim of this paper is to give a definitive construction of the duplicate of an algebra using divided powers. This means that no hypothesis is stated on the prime number 2. Of course, if 2 is inversible in the base ring, our construction coincides with the already known duplicate which uses symmetric powers. Moreover, we prove a Whitehead th(...)

Characterization of Anaerovibrio burkinabensis sp. nov., a Lactate- Fermenting Bacterium Isolated from Rice Field Soils
ABOUBAKAR S. OUATTARA,' ALFRED S. TRAORE,, AND JEAN-LOUIS GARCIA'"
A strictly anaerobic, gram-negative bacterium was isolated from rice field soils by using lactate as a sole
carbon and energy source. The cells were non-spore-forming, motile, curved rods. Optimal growth occurred
at 35°C and pH 6.8. No NaCl requirement was observed. Vitamins were required for growth. Our isolate,
strain B4BoT (T = type stra(...)

Clear sky radiation as a function of altitude
D. BATHIEBO
Using a numerical integration (Lowtran 6 code) stopped at several arbitrary base altitudes, in association with measurements from sounding balloons, clear sky radiation is determined as a function of the altitude parameter. The relations established, and the properties attached, are studied. In application, a natural system to obtain dew in dr(...)

Dupliquée d'une algèbre et le théorème d'Etherington
M. OUATTARA
Résumé Le but de cet article est d'expliciter la structure de la dupliquée d'une algèbre. On montre que, sur un corps commutatif K, si la sous-algèbre A 2 d'une K-algèbre A est une algèbre pondérée, une T-algèbre ou une algèbre génétique, alors la dupliquée D (A) de l'algèbre A est respectivement, une algèbre pondérée, une T-algèbre ou une alg(...)

Sur les algebres de Bernstein qui sont des T-algebres
M. OUATTARA
In this note we show that for finite-dimensional Bernstein algebras over a field of characteristic different from 2: 1.(1) The principal nilpotency of an element implies its strong nilpotency. 2.(2) If Ker (ω) is a nil algebra, then it is a train algebra. 3.(3) Every train algebra of dimension n⩽ 5 is special train algebra, and that is a best(...)

Autour de la dupliquee
M. OUATTARA
Cet article concerne la dupliquee D (A) d'une algebre A. Dans [l] et [2], Boers traite du probleme de la caracterisation des algebres A dont la dupliquee D (A) est associative ou strictement 4-associative. De plus, si I/est l'ideal associateur de D (A), il examine les conditions pour avoir l'isomorphisme &4)/VA. Nous repondons ici a toutes ces(...)

Sur les T-algebres de Jordan
M. OUATTARA
Résumé On étudie, en caractéristique différente de 2, l'aspect algèbre de Jordan des T-alg e ̀ bres. On montre que, pour les T-alg e ̀ bres de rang 3, être une algèbre de Jordan équivaut à être à puissances associatives et leur équation rang est de deux formes. Dans certains cas, on détermine l'ensemble des idempotents. On montre enfin que tou(...)

Sur les algèbres de Bernstein d'ordre 2
M. OUATTARA
We show that the duplicate of an nth order Bernstein algebra is a Bernstein algebra of order n+ 1, and we characterize the set of generalized idempotents in such an algebra. We also characterize those Bernstein algebra of order 2 which are Jordan or are power associative. The results are quite different from what is true for Bernstein algebras(...)

"The Fantastic Narrative in Elechi Amadi's Works: Narrating and Narration"
KIEMA, Alfred
Thanks to a particular narrator and narrative, Elechi Amadi makes the reader hesitate between natural and supernatural explanations to events. By so doing his narratives appear fantastic.

Abstract:The spectra of iron(II) phthalocyanine polymer complexes (FePcL)n with bispyridinato bridging ligands, where L = 44’-bipyridine (bpy), trans-1,2-(4-pyridyl)ethylene
