CONSTRUCTION OF A CLASS OF COPULAS WITH HORIZONTAL OR VERTICAL SECTION OF A HOMOGRAPHIC FUNCTION
Herman Tiemtoré, Bagre Remi Guillaume, Loyara Vini Yves Bernadin
The construction of multivariate distributions with arbitrary margins has been a problem of interest to statisticians for many years, but nowadays, by virtue of Sklar’s theorem, this problem can be reduced to the construction of a copula. However, there is no general method for constructing a copula. In order to provide a partial solution to t(...)

Variation in fruits and seeds traits of Saba senegalensis (A.DC.) Pichon along a climatic gradient in Burkina Faso, West Africa: implications for its sustainable management
Sata Diawara, Fidèle Bognounou, Patrice Savadogo, Amadé Ouédraogo
Environmental heterogeneity and genetic variation may be reflected in the within-species variation of different fruit traits. These traits related variations are important for guiding the process of adapting wild plants for human use through domestication. Saba senegalensis (A.DC.) Pichon is a multi-purpose woody liana found throughout sub-Sah(...)

Selon l'Organisation mondiale de la santé (OMS), en 2004, les maladies digestives constituaient la huitième cause de décès. En Afrique, des données manquent sur la prévalence globale de ces pathologies. Notre étude s’ est intéressée à la prévalence des différentes pathologies hépathobiliaires dans le service de médecine interne, d’endocrinolog(...)

Mise en place de valeurs de références pour les paramètres hématologiques par méthodes indirectes au Burkina Faso: Résultats d’une étude préliminaire
Koumpingnin Nebie, Salam Sawadogo, Myriam Nikiema, Fabienne Sanou, Catherine Traore, Charles Sawadogo, Eleonore Kafando
Introduction : L’hémogramme est l’une des analyses de biologie médicale les plus prescrites en pratique médicale. Comme pour tout paramètre biologique, son interprétation se fait par comparaison à des valeurs de références (VR) prédéfinies et adaptées à la population d’origine du patient. Or, la majorité de nos pays utilisent des valeurs de ré(...)

Role of soluble guanylate cyclase and muscarinic receptors in the relaxant effect of Waltheria indica L. (Malvaceae) on tracheal smooth muscle
Zakaline Yabré, Rainatou Boly, Charaf El Khattabi, Maurice Ouédraogo, Raogo Ouédraogo, Abdoul Gilchrist Laurent Boly, Moussa Ouedraogo, Rasmané Semdé, Noufou Ouédraogo, Stephanie Pochet and Noëla Hoho Estelle Youl
Waltheria indica L. (Malvaceae) has been recognized in traditional medicine for its various therapeutic effects, including anti-inflammatory, antioxidant, anticancer, and bronchorelaxant activities. This study aimed to investigate the relaxant effects of W. indica extracts on rat tracheal smooth muscle and explore the involvement of β2-adrener(...)

Evaluation of Body Composition in Senegalese Patients with Chronic Respiratory Disease
Sow A. K ., Diaw M., Ouedraogo V., Tiendrebeogo A. J. F., Coly M. S. , Ba A., Diagne/Huondjo S., Toure M., Seck A., Mbengue A, Ba A. & Samb A.
Background: Body composition could increase morbi-mortality occurrence risk of patients with chronic respiratory disease (CRD). In low income countries, this relation was less studied. Thus, our study aimed to evaluate the body composition in patients with CRD.
Methodology: Study participants were asthmatic or chronic obstructive disease (CO(...)

Plant material yield evaluation for hepatoprotective plant rational use in Burkina Faso, West Africa
Souleymane Compaoré, Tata Kadiatou Traoré, Lazare Belemnaba, Salfo Ouédraogo, Noufou Ouedraogo, Sylvin Ouedraogo and Adjima Thiombiano
This study aims to contribute to the sustainable use of plant resources. Thus, 38 species with hepatoprotective potential were sampled in several locations of Burkina Faso between May and October 2021. These species were identified during previous surveys with traditional healers. These plants' leaves, roots, and trunk barks were collected and(...)

Water and its biological resources sustainability in tropical developing countries: aquatic ecosystems health assessment
Idrissa Kaboré , Otto Moog , Adama Oueda, Andreas Melcher
To response to ongoing threats from human pressures and climate changes, water managers and users need a visual tool that provide accurate information of waterbodies health
for decision making to promote sustainable management practices. However, there is a lack of less sophisticated tools, such as biotic score, to assess the health of aquati(...)

Mullite effect on the ceramic filters effectiveness in the removal of arsenic from borehole water from Burkina Faso
Kassoum Barry, Gisele Laure Lecomte-Nana, Nassio Sory, Moussa Ouedraogo, Loukou Sawadogo, Moustapha Sawadogo, Issaka Sanou, Mohamed Seynou, Lamine Zerbo, Philippe Blanchart
The intrinsic technological characteristics depend on the forming process and the application for which the
materials are intended. A clay raw material (75 mass%) which is rich in melting oxides and waste peanut shells
(25 mass%) were used to manufacture porous ceramics for the removal of arsenic from borehole water in Burkina
Faso. A bo(...)

On exponential stability of mild solution of a stochastic integrodifferential equation in a complex Hilbert space
Wahabo BAGUIAN; Victorien KONANE; Claude YAMEOGO
In this work, we consider a system of stochastic integrodifferential
equations in a complex Hilbert space. We first establish the existence
and uniqueness of mild solutions for equation (1) under non-Lipschitz
conditions. Then we show under certain assumptions that the found
mild solution is exponentially stable on average of order n. Note(...)

Infinite-Horizon Probability of Ruin for a Variable-Memory Counting Process (Hawkes Process)
Souleymane Badini, Frédéric Béré, Delwendé Abdoul-Kabir Kafando
The reserve R(t) of an insurance company denotes the accumulated capital up to time ttt throughout its operational span. While this reserve can be modeled using stochastic processes, the endeavor remains notably intricate. The mathematical complexity presents a considerable obstacle for researchers within this domain. Prior research has predom(...)
