Study of the organoleptic quality of three varieties of dried mangos : Amélie, Lippens and Brooks during storage by enzymatic tanning techniqueof peroxidases (POD) and the polyphenoloxydases (PPO)
Aminata Belem , François Tapsoba , Laurencia Toulsoumdé Songre-Ouattara , Cheikna Zongo , Aly Savadogo *
Thirty dried mango samples of Amélie, Brooks and Lippens varieties were collected for physico-chemical analyses to understanding the conditions of appearance of the enzymatic browning. These analyses showed that the higher contents of dry matter, assayable acidity, vitamin C and phenolic substrates were respectively 95,86 ± 0.01 mg/g; 1.56 ± 3(...)

Water flow in soil at small water contents: a simple approach to estimate the relative hydraulic conductivity in sandy soil
M. B. Kebré, F. Cherblanc, F. Ouédraogo, F. Jamin, B. Naon, F. Zougmoré & J.-C. Bénet
Unsaturated soil hydraulic properties are key properties in the fields of soil science and civil engineering. Because of their strong dependence on water content, there are considerable experimental and numerical difficulties in their determination, specifically in the dry range. This situation is encountered regularly in arid and semi-arid re(...)

Visual appearance durability as function of natural and acceleratedageing of electrophoretic styrene-acrylic coatings: Influence of yellowpigment concentration
Tambi Ramdé, Luiz Gustavo Ecco, Stefano Rossi
Organic coatings are extensively used in many fields of engineering such as automotive or architectural industries for protection of the metallic structure against corrosion and to deliver visual aspects to the coated item. High quality paints either for outdoor or indoor applications require longer stability of their visual appearance alongsi(...)

Groundwater arsenic contamination in Burkina Faso, West Africa: Predicting and verifying regions at risk
Anja Bretzler, Franck Lalanne, Julien Nikiema, Joel Podgorski, Numa Pfenninger, Michael Berg, Mario Schirmer
Arsenic contamination in groundwater from crystalline basement rocks in West Africa has only been documented in isolated areas and presents a serious health threat in a region already facing multiple challenges related to water quality and scarcity. We present a comprehensive dataset of arsenic concen trations from drinking water wells in rura(...)

Dental emergencies in Burkina Faso Armed Forces
Raoul Bationo, Wendpouiré Patrice Laurent Guiguimdé, Hamidou Ouédraogo, Blintim Somé
Background. Dental emergencies affect the mission of deployed units. During military operations, the definition of dental emergency is different from that which is commonly accepted in dentistry. There is no notion of seriousness or need for urgent care. A considerable number of studies concerning American, French and other armies exist in the(...)

Relations sociales, réseau scolaire et stratégies intégratrices des élèves déficients visuels au Burkina Faso
ROUAMBA-OUEDRAOGO Claudine Valérie
Au Burkina Faso, l’organisation et le financement de la scolarisation des élèves déficients visuels relèvent du monde associatif avec une faible implication de l’Etat. L’intégration des élèves déficients visuels se fait difficilement face aux difficultés relationnelles dans les familles d’accueil, le relâchement du suivi de l’association, le m(...)

MULTIVARIATE RISKS MODELING FOR FINANCIAL PORTFOLIO MANAGEMENT AND CLIMATE APPLICATIONS
Yves Bernadin Vini Loyara, Remi Guillaume Bagré and Diakarya Barro
This paper investigates some properties of derivative measures of the Value at Risk (VaR) of random variables modeling the stochastic behavior of a portfolio asset. Specifically, coherentness and convex properties of the conditional, the tail VaR and the standard deviation are established. Moreover, a new version of high risk scenario is chara(...)

Incremental predictive value of mean platelet volume/platelet count ratio in in-hospital stroke after acute myocardial infarction
N. YAMEOGO
Stroke is a serious complication after acute myocardial infarction (AMI) and is associated with an increased risk of death. Though the pathophysiological mechanisms are not exactly known, increased inflammation and platelet reactivity could play an important role in the occurrence of stroke during AMI. We aimed to investigate the relationship(...)

POLYMORPHISME GENETIQUE DES CYTOCHROMES P450 : SYNTHESE METHODIQUE DES ETUDES PRIMAIRES EFFECTUEES DANS LA POPULATION AFRICAINE
ELIE KABRE, RAOUL KARFO, BOUKARE KASSONGO, JEAN SAKANDE , MAMADOU SAWADOGO
Il existe une grande variabilité interindividuelle de réponse aux médicaments, tant en terme d’efficacité que de toxicité. Pour comprendre cette variabilité, de multiples travaux de recherche sur le polymorphisme génétique des cytochromes P450 ont été menés de par le monde. Notre étude a pour but de faire le point des études réalisées en Afri(...)

Préambule aux opérateurs Fourier intégraux: les opérateurs pseudo-différentiels
Catherine Ducourtioux, Marie Françoise Ouedraogo
Dans ce travail, nous donnons une introduction aux opérateurs pseudodifférentiels en faisant une généralisation des opérateurs différentiels. Nous étendons ensuite ces opérations aux espaces de Sobolev puis aux espaces des distributions tempérées. Par la suite, nous étudions la continuité de ces opérateurs sur les espaces de Sobolev, ce qui pe(...)

Phytotherapeutical implications in pain perception-focusing focusing on schizophrenia
Iulia Antioch, Alin Ciobica, Moussa Compaoré, Adama Hilou, Martin Kiendrebeogo, Harquin Foyet, Samson Guenné
La schizophrénie est une des maladies psychiatriques extrêmement complexe dans laquelle la perception de la douleur est modifiée, allant de l'abolition à l'absence de tout type de changement par rapport aux témoins normaux et même à l'hypersensibilité. Ainsi, la gestion du phénomène de la douleur dans la schizophrénie a des implications inconn(...)
