Linking participatory and GIS-based land use planning methods : A case study from Burkina Faso
HESSEL Rudi, BERG Jolanda van den, KABORE Oumar, KEKEMA Arie van, VERZANDVOORT Simone, DIPAMA Jean-Marie, DIALLO Binta
Sustainable land use planning is crucial for realizing the aim of food security and for combating land degradation in the Sahel. A participatory land use planning workshop was organised in a village in the eastern region of Burkina Faso to investigate land use problems, their causes, effects and possible solutions. Participatory research tool(...)

Performance comparison of PRC based PAPR reduction schemes for WiLAN Systems
Hussain Sajjad, Guel Désiré, Louët Yves, Palicot Jacques
High Peak to Average Power Ratio (PAPR) is a main area of concern in multi-carrier communications as in Orthogonal Frequency Division Multiplexing (OFDM) modulated transmission. Several techniques have been devised to reduce the PAPR of the OFDM signal. One of these PAPR reduction techniques is based on Peak Reducing Carriers (PRC) concept whe(...)

Finding out Egyptian Gods’ secret using analytical chemistry: biomedical properties of Egyptian black makeup revealed by amperometry at single cells
I. TAPSOBA
Lead-based compounds were used during antiquity as both pigments and medicines in the formulation of makeup materials. Chemical analysis of cosmetics samples found in Egyptians tombs and the reconstitution of ancient recipes as reported by Greco-Roman authors have shown that two non-natural lead chlorides (laurionite Pb (OH) Cl and phosgenite(...)

The impact of pond depth and environmental conditions on sunlight inactivation of Escherichia coli and enterococci in wastewater in a warm climate
MAIGA Ynoussa, WETHE Joseph , DENYIGBA Kokou , OUATTARA Aboubakar Sidiki
Microcosm experiments were carried out under dark and real sunlight conditions in Ouagadougou (Burkina Faso) to investigate the survival of faecal indicators (Escherichia coli and enterococci) in secondary wastewater. Light damage was estimated by loss of bacterial culturability. The results clearly show that sunlight has a deleterious effect(...)

Combustion de granulés de polyéthylène pur et de sachets plastiques à base de polyéthylène : effet de la masse et de la température sur les émissions d’oxydes d’azote et de carbone et l’évolution de l’oxygène
Salifou Koucka Ouiminga, Thomas Rogaume, Bila Gérard Segda, Moussa Sougoti, Jean Koulidiati
Le présent travail est une étude expérimentale comparative des émissions d’espèces gazeuses lors de la combustion de granulés de polyéthylène pur et de sachets plastiques à base de polyéthylène. Deux paramètres importants de la dégradation thermique sont étudiés pour chacune des deux matrices : la température et la masse. Cette étude a été réa(...)

Permeability to water of sintered clay ceramics
D. BATHIEBO
The microstructural characteristics of sintered clay ceramics depend mainly on the clay type and thermal transformations. Different pore morphology and connectivity change the liquid water flow process through the material, as in the case of roof tiles which are progressively saturated with water during rain. In this study, 2 clays mined in Bu(...)

Rates of coverage and determinants of complete vaccination of children in rural areas of Burkina Faso
Sia, Drissa, Pierre Fournier, Jean-François Kobiané et Blaise Sondo
Burkina Faso's immunization program has benefited regularly from national and international support. However, national immunization coverage has been irregular, decreasing from 34.7% in 1993 to 29.3% in 1998, and then increasing to 43.9% in 2003. Undoubtedly, a variety of factors contributed to this pattern. This study aims to identify both in(...)

FFT/IFFT Pair Based Digital Filtering for the Transformation of Adding Signal PAPR Reduction Techniques in Tone Reservation Techniques
Guel Désiré and Palicot Jacques
Orthogonal Frequency Division Multiplexing (OFDM) suffers from a high Peak-to-Average Power Ratio (PAPR). Tone Reservation (TR) is a popular PAPR reduction technique that uses a set of reserved subcarriers to carry the peak reducing signal. The major advantages of TR technique include no transmission performance degradation, no transmission of(...)

A Figure-of-Merit for Evaluating the Overall Performance of OFDM PAPR Reduction Techniques in the Presence of High Power Amplifier
Guel Désiré and Palicot Jacques
One of the major drawbacks of Orthogonal Frequency-Division Multiplexing (OFDM) is the large envelope fluctuations which either require an inefficient use of High Power Amplifiers (HPA) or decrease the system performance. Peak to-Average Power Ratio (PAPR) is a very well known measure of the envelope fluctuations and has become the cost functi(...)

[Ceramic clay from Burkina Faso used in building construction]: Céramiques d'argile du Burkina Faso utilisées en construction immobilière
D. BATHIEBO
2 raw clays samples from Burkina Faso were analyzed in order to improve the ceramic process of roof tiles and small bricks manifacture. The major phases etected by X-ray diffraction in the 2 samples are kaolinite, illite, orthose and quartz. In addition, feeble quantities of albite and montmorillonite are also detected. The thermal behavior be(...)

Transformation grâce à un Filtrage Numérique des techniques "Ajout de Signal" en techniques "Tone Reservation" pour la Réduction du PAPR des Signaux OFDM
Désiré GUEL, Jacques PALICOT
L'OFDM (Orthogonal Frequency Division Multiplexing) souffre d'une grande variation d'amplitude caractérisée par un PAPR (Peak-to-Average Power Ratio) élevé. La "Réservation Tone" (TR) est une technique de réduction de PAPR qui utilise un ensemble de porteuses réservées pour transmettre le "signal de réduction du PAPR". Du f(...)
