New potent 3-dehydroquinic acid (AQs) inhibitors of 3-dehydroquinate dehydratase (dehydroquinase type II) of Mycobacterium tuberculosis (MtDHQ2) were obtained by using structure-based molecular design via the in situ modification of the template inhibitor AQ1 within the MtDHQ2-AQ1 crystal structure (PDB ID: 2XB8), in order to describe the interactions upon the formation of the complex MtDHQ2-inhibitor. A training set of 14 AQs with known inhibition constants (Kiexp) was used to establish a quantitative structure-activity relationship (QSAR) model for correlating the pKiexp (pKiexp = ‑log10 (Ki...

This study presents the water adsorption isotherms of fermented cocoa beans obtained by drying natural sun. They were determined at 20, 30 and 40 ° C by the static gravimetric method. Equilibrium is obtained after 33 days for the final point. Mathematical models commonly used in the literature to describe the food products have helped explain the hygroscopic behavior during conservation. The regression analysis was performed under the Excel 2013 software, using the non-linear solver GRG algorithm in order to determine the coefficients models.

Inadequate handling, processing and sales of meat products have resulted in microbial contamination responsible for most infectious human food-borne illness. The study conducted a stochastic assessment of the risk of infection linked to the consumption of braised beef meat “Choukouya” contaminated by Clostridium perfringens in Côte d’Ivoire. We conducted “Choukouya” consumers (n = 900) and vendors (n = 300) survey to characterize the actors behavior. 189 samples of “Choukouya” were collected and microbiologically analyzed according to French standard protocols NF V 08-061 and XPV 08-06...

The quality of preserved sodium bicarbonate powder is largely dependent on its moisture content, moisture migration and moisture uptake of the sodium bicarbonate during storage. Therefore, the water activity level, which corresponds to a range of equilibrium moisture contents, must be determined by, for example, the use of moisture isotherms. Sorption isotherms are therefore of great importance in post-harvest procedures, especially for predicting drying and storage, which help to establish the final moisture content of the product under certain environmental condition. Moisture sorption i...

The aim of this study is to check if remittances and aid are complements or substitutes in the growth process in West African Economic Monetary Union (WAEMU). Clearly it aims to check if remittances and aid complete each other to increase economic growth. By using data on the sample of WAEMU Countries with panel Dynamic Ordinary Least Squares (DOLS) on the period 1980-2015, the results show that remittances and aid have a substitution link. The results also highlight that remittances have a negative effect on growth, but aid has no significant effect on growth.

Abstract Good Agricultural Practices (GAPs) have been widely promoted to improve productivity, sustainability, and quality in Côte d'Ivoire's cashew sector. However, the determinants and extent of adoption of GAPs among farmers remain poorly understood to date. This study estimates the actual and potential adoption rates of key GAPs and analyzes the socio-economic, institutional, and behavioral factors influencing farmers' uptake. Using survey data from 844 cashew producers and employing Probit and Average Treatment Effect (ATE) models, we find that while awareness of GAPs is relatively high,...

Côte d’Ivoire, the world's leading cashew nut producer with 1,200,000 tons in 2022, faces low productivity of raw cashew nuts (350–500 kg/ha) due to the limited adoption of Good Agricultural Practices (GAP). This study explored the relationship between producers' perceptions and GAP adoption, identified factors influencing both the adoption and intensity of GAP use, and assessed the impact of GAP adoption on cashew nut yield. Using probit, Poisson regression, and marginal treatment effect models on data from 845 cashew producers, we found that plot preparation, direct seeding, shaping pruning,...

Cet article examine certaines implications théoriques du modèle de planification intertemporelle Oslo-Le Caire (le modèle de canal). Une version du modèle de canal incluant des projets d'investissement privés et publics est développée. Les propriétés d'optimalité du modèle sont dérivées. Il est démontré que : (i) la solution de Pareto peut être soutenue par des prix compétitifs et (ii) un critère de classement peut être construit dans l'esprit de l'analyse coûts-avantages. Les résultats alignent théoriquement le modèle de canal avec les modèles classiques d'allocation des ressources.

L’objectif de cette étude est de déceler lesquels des aides publiques et des transferts des migrants s’avèrent plus bénéfiques pour améliorer le capital humain dans les pays de l’Union Economique et Monétaire Ouest Africaine (UEMOA). Le capital humain est mesuré par la qualité de l’éducation qui prend en compte le nombre d’années d’études et le rendement de l’éducation. A l’aide de la méthode Dynamic Ordinary Least Squares (DOLS) et des régressions Quantiles en Panels, les résultats ont montré que les transferts des migrants améliorent le capital humain alors que les aides publiques ont...

Abstract African herbaceous biomes will likely face drastic changes in the near future, due to climate change and pressures from increasing human activities. However, these biomes have been simulated only by dynamic global vegetation models and failing to include the diversity of C 4 grasses has limited the accuracy of these models. Characterizing the floristic and physiognomic diversity of these herbaceous biomes would enhance the parameterization of C 4 grass plant functional types, thereby improving simulations. To this end, we used lowermost and uppermost values of three grass physiognomic...

Dans le souci de mieux comprendre et gérer la qualité des eaux de surface, l’on entreprend souvent de longues et fastidieuses campagnes d’analyses. Celles-ci génèrent généralement assez de données dont l’interprétation n’est pas toujours aisée. L’application de l’analyse en composantes principales (ACP) pour une telle tâche pourrait être salutaire. C’est dans l’optique d’une telle application que 22 paramètres physico-chimiques, provenant de l’analyse d’échantillons d’eau collectés entre Février 2007 et Avril 2008 sur 17 stations reparties sur 9 lacs du système lacustre de Yamoussoukro, o...

Nitrogen compounds, including nitrates, are threatening the quality of water in the Continental Terminal aquifer in the Abidjan district. Consumption of nitrate-rich water (over 50 mg/l) can have harmful effects on human health. This study was prompted by the observation that nitrate levels were high in the water from certain boreholes in the Adjamé Nord catchment area, with the aim of reducing nitrate levels in drinking water. To achieve this objective, the water from a borehole was filtered on a weakly basic anionic resin pilot plant to reduce the nitrate content in the drinking water. The v...

0bjectif : Évaluer la qualité chimique et microbiologique des laits caillés (laits fermentés artisanaux) produits dans la ville de Yamoussoukro (Côte d’Ivoire). Méthodologie et résultats : Après une enquête sociologique portant sur une population de 370 producteurs, 100 échantillons de lait caillé ont été prélevés à travers la ville de Yamoussoukro et analysés. La flore totale aérobie mésophile, les coliformes totaux, Escherichia coli, Salmonella spp., le pH et l’acidité titrable ont été déterminés. Les charges moyennes de la flore aérobie totale étaient de 8,20 ± 9,1.104UFC/mL à 1,47 ±...
