Sur les algèbres de Bernstein d'ordre 2
M. OUATTARAWe 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...

UV-VISIBLE AND IR SPECTRA OF IRON(II) PHTHALOCYANINE POLYMER COMPLEXES LINKED BY BIS-PYRIDINATO LIGANDS
KARIFA BAY0, GUY VENANCE OUEDRAOGO, GEORGES TERZIAN and DAVID BENLIANAbstract: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
(bpe), 1,2-bis-(4-pyridyl)ethane (bpa), are discussed in comparison with the spectra of FeIIPc
and FePcL'2, where L’...

From spectral clear sky emissivity to total clear sky emissivity
D. BATHIEBOFrom standard and observed atmospheric profiles a simple model to compute the spectral sky emissivity has been built, and compared with Lowtran-6 code calculations. In the present paper, it is analytically integrated. The relations expressing the total emissivity point out a small effect of...

Expressions for computing the radiative cooling flux from the sky in different climates
D. BATHIEBOSky radiation affects numerous systems but is often under estimated. This paper is especially oriented towards its determination in hot countries for cooling purposes. It includes expressions for clear weather conditions and shows some properties and the power of the flux according to the...

Assessment of the flora of Burkina Faso
A. OUEDRAOGOSixteen years after the last comprehensive checklist of Burkina Faso, about 30% more species have become known for the country's flora. Many of these are documented in the herbarium collections of the University of Ouagadougou (OUA) and the Herbarium Senckenbergianum (FR). Nevertheless some...
