Aims: The energy domain is responsible for the production of many gaseous, liquid and solid pollutants, strongly contributing to climate change. The provision of bioclimatic habitats to households is therefore necessary since it will contribute to the reduction of energy consumption. This work consists in making a study of the thermal behavior(...)

Fertility transition in Dakar, Nairobi and Ouagadougou since the 1970s: an identical reduction at all ages through modern contraception?
Millogo Roch, Rossier Clémentine
While some researchers have predicted a fertility transition in sub-Saharan Africa similar to that witnessed in Europe, Latin America, or Asia, where practices of fertility limitation and long-term contraception have played a major role, others believe that it will differ. The aim of this article is to contribute to this debate, testing Caldwe(...)

Numerical Study of the Effect of Henry’s Constant on the Mechanisms of pesticides Transfer in The Superficial Layers of Hygroscopic Soils
Samuel Ouoba, Auguste A. Soré, Abdoulaye Kaboré and Jean Koulidiati
We describe the transfer mechanisms of pesticides in hygroscopic soils. The work consisted in using Henry’s constants of five pesticides to study the transfer mechanisms. The numerical work consisted to make a soil sample of height h with initial water content w0 and initial pesticide concentration C0 placing it in an ambient atmosphere

Enhancing food production to prevent households from food insecurity in rural Burkina Faso: Does land ownership matter?
SEOGO Windinkonté
Purpose – This paper assesses the effect of land ownership on household food security through its
productivity enhancement effect in rural Burkina Faso.
Design/methodology/approach – As the link between land tenure security and productivity is indirect, the
study relies on a complex mixed process regression model with robustness to assess t(...)

Purification potential of local media in the pre-treatment of greywater using vertical biofilters under Sahelian conditions
COMPAORE Cheik Omar Tidiane, MAIGA Ynoussa, OUILI S. Amidou, NIKIEMA Mahamadi, OUATTARA Aboubakar Sidiki
Several on-site greywater treatment systems are under development including biofiltration, whose efficiency is influenced by the filter media. Therefore, the main objective of this study was to evaluate the influence of the type of filter media and their grain size in the removal of organic and microbial pollutants from greywater. Hence, three(...)

Factors affecting sustainable agricultural intensification in Burkina Faso
MARE Tobignaré Florent; ZAHONOGO Pam; SAVADOGO Kimseyinga
Farmers in Burkina Faso, as in Sub-Saharan Africa overall, face multiple combined difficulties like water stress, continued land degradation and low soil fertility due to climate change effects. To simultaneously overcome these difficulties, where agriculture accounts for more than a third of GDP, intensifying Sustainable Agricultural Practice(...)

Simulation and Experimentation of Water Heating in a Metal Tube Placed in a Solar Collector
Boureima Kaboré, Germain Wende Pouiré Ouedraogo , Boukaré Ouedraogo, Salia Drabo, Sié Kam, Dieudonné Joseph Bathiebo
Our work relates to a numerical and experimental study of a solar exchanger designed and tested in Laboratory of Renewable Thermal Energy. This device is a unit for transforming solar radiation into thermal energy. The objective of our work is to study the evolution of temperature in the solar collector-water system. Our results show that t(...)

Can Plasmodium falciparum Induce Homocysteinemia in Malaria Patients?
Noé Yaméogo, Abdoul Karim Ouattara, Bapio Valérie Bazié, Alfred Rakissida Ouédraogo, Florencia Wendkuuni Djigma, Jacques Simporé
Background
Plasmodium falciparum has developed elaborate strategies to survive in the hostile intracellular environment of the infected host cell, including resistance to oxidative stress. Cysteine is a metabolic product of homocysteine and a precursor of the antioxidant glutathione used by Plasmodium falciparum to escape harmful oxidation.(...)

Non-local boundary inclusion problem with L1-data and constant exponent
A. KAboré, S. Ouaro
In this work, we study the following elliptic problem −diva(x,∇u)+β(u)∋f in Ω, with non-local boundary conditions. We prove the existence and uniqueness of entropy solution for L1-data f.

The human immunodeficiency virus (HIV) belongs to the Retroviridae family and remains a public health problem in sub-Saharan Africa. Recent reports from WHO have shown that 33 million people died from HIV infections. HIV is one of the most serious fatal human diseases of the 20th and 21st centuries. However, variations in genetic and immunolog(...)

Caractérisation du processus de traitement des eaux usées des unités industrielles dans la station de traitement de Kossodo mise en place par l’Office Nationale des Eaux et l’Assainissement (ONEA) au BURKINA FASO
GOUBA Bernard , SAWADOGO Boukari
Les eaux usées des stations de traitement de Kossodo dans la ville de Ouagadougou ont un impact négatif sur l’environnement et sur la population. Pendant plusieurs années la zone de Kossodo est réputée à cause de son odeur nauséabonde due aux eaux usées. Nous avons effectué une étude de terrain afin de mieux caractériser la station d’épuration(...)

Local existence and regularity of solutions in alpha-norm for some partial functional integrodifferential equations in Banach spaces
Djendode Mbainadji and Issa Zabsonre
By using the resolvent operator theory in the sense given by Grimmer in [1], we prove the existence and regularity of solutions in α-norm for some partial functional integrodifferential equations in Banach spaces. We firstly show the existence of the mild solutions and give some conditions for the existence of strict solutions.
