Approximation of the average power variation for Geometric adding signal approach of PAPR reduction in context of OFDM signals
Désiré Guel, Jacques Palicot
One of the major drawbacks of adding signal techniques of reducing peak to average power ratio (PAPR) is the variation of the average power of the transmit signal that undoubtedly degrades the performance of transmission. In this paper, assuming that the baseband OFDM signal is characterized as a complex Gaussian process, we derive an approxim(...)

Volatile constituents, antioxidant and antibacterial properties of Daniella Klainei Pierre ex A. Chev. essential oil
Jean Koudou, Louis-Clément Obame , Prosper Edou , Ismael Bassolé , François Eba , Gilles Figueredo , Alfred S. Traore and Jean-Claude Chalchat
The water-distilled oil obtained from rhizomes of Daniella Klainei Pierre ex A.Chev (Caesalpiniaceae)
from Gabon was examined by gas chromatography (GC) and gas chromatography/mass spectrometry
(GC/MS). The major constituent is myrcene (55.42%) along with -pinene (5.39%), -humulène (8.09%)
and Germacrene-D (6.06%). The essential oil posse(...)

« La traduction du langage religieux catholique comme dialogue interculturel et interconfessionnel chez les moose du Burkina-Faso
Alain Joseph Sissao
We will try to examine through the trajectory of the Catholic
biblical texts the translation process of French to the Moor of some texts and
religious concepts. Thus, through the hermeneutics of the biblical text, the
liturgy of French to the Moor will be analyzed in order to see the
intercultural and interdenominational elements between l(...)

Frequency based asymptotic distribution of the PAPR for geometric adding signal approach in OFDM signals context
Guel, D. and Palicot, J. and Bellanger, J.-J.
The distribution of the peak-to-average power ratio (PAPR) for Geometric method [1] of PAPR reduction in orthogonal frequency-division multiplexing (OFDM) signals is evaluated in order to analyse the influence of the carrier frequency of adding signal on the PAPR reduction. Assuming that the baseband OFDM signal is characterized as a band-limi(...)

Numerical study of cooling water via an evaporatively cooled immersed porous tube
D. BATHIEBO
We present a numerical study of the cooling of a volume of water through the wall of a cylindrical terracotta tube, the pores of which are saturated with water. The internal surface of the wall carries a water film which evaporates by forced convection of hot and dry air. Taking into account the physical properties of the material and that the(...)

Chemical composition, antioxidant and antimicrobial properties of the essential oil of Dacryodes edulis (G. Don) H. J. Lam from Gabon
L. C. Obame , P. Edou , I. H. N. Bassolé , J. Koudou , H. Agnaniet , F. Eba and A. S. Traore
The essential oil obtained by hydrodistillation from the resin of Dacryodes edulis (G. Don) H. J. Lam was simultaneously analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Twenty four components were identified in the essential oil and the main components were sabinene (21.8%),(...)

Provitamin A carotenoid content of dried fermented cassava flour: The effect of palm oil addition during processing
Inocent Gouado , Adelaide Demasse Mawamba , Ruphine Solange Meyimgo Ouambo , Issa Touridomon Some and Tchouanguep Mbiapo Félicité
Vitamin A deficiency is a public health problem in developing countries. Cassava is a major staple food for most Africans. Most often, it is processed into dried fermented cassava (commonly called gari) to limit post harvest losses. The white or yellow type of gari can be obtained without or with the addition of red palm oil respectively. Howe(...)
