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(...)

Algèbres de Jordan et algèbres génétiques
M. OUATTARA
Résumé L'objet de ce travail est de montrer comment les algebres de jordan interviennent en genetique. Nous montrons dans ce travail que toute algebre de jordan genetique sur un corps commutatif de caracteristique differente de 2 est une t-algebre speciale. Nous etablissons, en particulier, l'existence de deux types d'algebres de jordan parmi(...)

Assessment of heterocyclic aromatic amines contents in flamed and braised chicken in Burkina Faso
Bazoin Sylvain Raoul Bazie, Adjima Bougma, Aminata Sere, Judicael Thomas Ouilly, Hassane Sangare, Elie Kabre, Aly Savadogo, Djidjoho Joseph Hounhouigan, Marie-Louise Scippo, Imael Henri Nestor Bassole
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(...)

Equivalent susceptibility of Anopheles gambiae M and S molecular forms and Anopheles arabiensis to Plasmodium falciparum infection in Burkina Faso
A. GNEME
The Anopheles gambiae sensu lato (sl) species complex in Burkina Faso consists of Anopheles arabiensis, and molecular forms M and S of Anopheles gambiae sensu stricto (ss). Previous studies comparing the M and S forms for level of infection with Plasmodium falciparum have yielded conflicting results. Mosquito larvae were sampled from natural p(...)

Régénération sexuée de Boswellia dalzielii Hutch., un arbre médicinal de grande valeur au Burkina Faso
A. OUEDRAOGO
Résumé Boswellia dalzielii Hutch. est une plante principalement utilisée en pharmacopée traditionnelle. Elle compte parmi les espèces les plus menacées à l'est du Burkina Faso. L'espèce subit un écorçage intensif, qui la met en péril, et sa régénération est faible. Une collecte de fruits a été réalisée dans plusieurs peuplements pour étudier l(...)

In vitro assay of potential antifungal and antibacterial activities of extracts of Borassus aethiopum Mart
E. KABRE
The anti-inflammatory, antipyretic, and pro-apoptotic properties of extracts of Borassus aethiopum have been reported in the literature. In this study, we investigated the antifungal and antibacterial properties of Borassus aethiopum male inflorescences extracts. The antifungal and antibacterial activity was studied by agar well diffusion meth(...)

Evidence of diversity and recombination in Arsenophonus symbionts of the Bemisia tabaci species complex
Maternally inherited bacterial symbionts infecting arthropods have major implications on host ecology and evolution. Among them, the genus Arsenophonus is particularly characterized by a large host spectrum and a wide range of symbiotic relationships (from mutualism to parasitism), making it a good model to study the evolution of host-symbiont(...)

Detection of G119S ace-1 R mutation in field-collected Anopheles gambiae mosquitoes using allele-specific loop-mediated isothermal amplification (AS-LAMP) met...
A. BADOLO
Malaria vectors have developed resistance to the four families of insecticides available for public health purposes. For example, the kdr mutation is associated with organochlorines and pyrethroids resistance. It is of particular concern that organophosphate and carbamate resistance associated with the G119S ace-1 R mutation has recently incre(...)

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(...)

Herbarium collections and field data‐based plant diversity maps for Burkina Faso
A. THIOMBIANO
ABSTRACT A map of plant species diversity in Burkina Faso is presented based on field observations and specimen data from the Ouagadougou University Herbarium (OUA) and the Herbarium Senckenbergianum (FR). A map of collecting intensity and field observations illustrates centres of botanical research activities in Burkina Faso. To overcome prob(...)

Screening of silent myocardial ischaemia by dobutamine stress echocardiography among type 2 diabetics at high cardiovascular risk in Senegal
N. YAMEOGO
INTRODUCTION: Diabetes is a major risk factor for coronary artery disease witch may develop insidiously. Several non-invasive methods are used to detect silent myocardial ischaemia, especially in diabetic patients at high cardiovascular risk. We project to screen, by dobutamine stress echocardiography, silent myocardial ischaemia in type 2 dia(...)

Do floristic composition, plant species abundance and vegetation structure in Sudanian wetlands vary according to conservation status?
B. NACOULMA
In Sahel, wetlands are particularly endangered hence practical knowledge for their sustainable management is needed. The aim of this study was to compare plant community structure between protected and unprotected wetland bank stands in eastern Burkina Faso. Phytosociological and dendrometrical parameters were carrying out in adult trees, seed(...)
