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 BENLIAN
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
(bpe), 1,2-bis-(4-pyridyl)ethane (bpa), are discussed in comparison with the spectra of FeIIPc
and FePcL'2, where L’ = pyridine, 4-cyanopyridine (4CNpy), in reference to(...)

From spectral clear sky emissivity to total clear sky emissivity
D. BATHIEBO
From 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 hygrometry. They are discussed and compared with thos(...)

Expressions for computing the radiative cooling flux from the sky in different climates
D. BATHIEBO
Sky 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 climates. Observations in Kuwait and in the Ivory Coast(...)

The nutritional status of meat is tarnished by its association with the induced cooking contaminants. The aim of this study was to assess the heterocyclic aromatic amines profile and contents in processed chicken in Burkina Faso. Eight polar and apolar heterocyclic aromatic amines (HAAs) including 2-mino-3-methylimidazo[4,5-f]quinolone (IQ), 3(...)

Li-Sn and Pb-Zn Type Mineralization in the Birimian Greenstone Belt of Banfora. Recommendations for the Exploration of Strategic and Base Metals, Burkina Faso, West Africa
Abdoulaye Ouédraogo, Kafohé Azise Héma, Mamadou Nimi, Seta Naba, Urbain Wenmenga
Regional exploration of base and strategic metals (Li, Nb, Ta, Sn) in the Kangounadéni sector, part of the Banfora Belt (Paleoproterozoic greenstone belt, West African Craton), was conducted using stream sediment and soil sampling around the two-micas leucogranite of Ferkessédougou. In this study, a total of 281 stream sediment samples and 640(...)

Detection of mutation by allele-specific loop-mediated isothermal amplification (AS-LAMP)
A. BADOLO
For effective control of pathogen-transmitting mosquitoes, precise surveillance data of mosquito distribution are essential. Recently, an increase of insecticide resistance due to the kdr mutation in Anopheles gambiae, a mosquito that transmits the malaria parasite, has been reported. With the aim of developing a simple and effective method fo(...)

Congenital malformations and medical conditions associated with orofacial clefts in children in Burkina Faso
K. NAGALO
Orofacial clefts are usually isolated cases but can be associated with other congenital malformations that are either recognised or unrecognised syndromes. The reported prevalence and pattern of such associated malformations, however, vary among studies. Objectives: To assess the frequencies and aetiologies of congenital malformations and asso(...)

Huge right atrial myxoma revealed by right heart failure
N. YAMEOGO
Right atrial myxoma is a heart benignant tumor characterized by an important clinical polymorphism. We report a case of a 30-year-old female with a diagnosis of a big right atrial myxoma. The diagnosis has been done by transthoracic echocardiography which showed an important tumorous mass in the right atrium. It was moving, inhomogeneous and t(...)
