Abstract This study was carried out with the aim of reusing waste water from the Me factory by proposing an innovative and sustainable solution, with a view to reducing the environmental impact of discharges and maximizing the reuse of this precious water resource. This involves proposing a recirculation system which will make it possible to use all of the water discharged while maintaining water quality at levels consistent with environmental standards. To do this, physicochemical and bacteriological analyzes were carried out on the waste water in order to assess their quality. Then, the Draw...

On the world scene, the energy requirements are mainly based on fossil fuels, however, these compounds reserves are finite and their exploitation has caused serious environmental problems. As a consequence, the demand for alternative renewable sources has been intensified in substitution the rising demand for energy and raw materials. The biomass is emerging as one of the few sources that have potential to meet these challenges of sustainability, as is currently the largest energy resource in the world, and only carbon-rich material available on the planet, apart from fossils.

In order to study the microbiology of chromium tolerance and reduction at a fly ash dumping site in South Africa, 15 core samples were investigated. It was shown that the 30 year old dumping site exhibited high concentrations of Cr (VI) ranging from 1.6 to 9.6 mg/g. From this contaminated fly ash dumping site, 67 chromium resistant bacteria (CRB) growing in liquid medium in presence of a high chromium concentration (500 μg/ml) were isolated. Full sequencing and phylogenetic analyses of the 16S rRNA gene allowed unambiguous identification of five Staphylococci species distributed nonhomogeneous...

Chemical variability of a plant from various continents or collected in different localities is well known and justifies its different biological activities. Thus, the present study was undertaken to evaluate the chemical variability of essential oils from leaves of Tridax procumbens Linn from five localities of Cote d'Ivoire. Essential oils have been extracted by hydrodistillation with yields varying from 0.077 to 0.079% depending on the locality. Gas chromatography and mass spectrometry analysis of essential oils showed a predominance of thymol (20.9 to 68.9%) in the oils from all the locali...

The exploitation of systems using solar energy as a source of energy is not fluctuations free because of short passage of clouds on solar radiation. The amplitude, the persistence and the frequency of these fluctuations should be analyzed with appropriate tools, instead of focusing on their location over time. The analysis of these fluctuations should use the instantaneous clearness index whose distribution is given as a first approximation which is independent not only of the season but also of the site. It is important to evaluate the potential solar energy in a region. Indeed such evaluatio...

AbstractThe classification methods are diverse and variety from one field of study to another. Among botanists, plants classification is done manually. This task is difficult, and results are not satisfactory. However, artificial intelligence, which is a new field of computer science, advocates automatic classification methods. It uses well-trained algorithms facilitating the classification activity for very efficient results. However, depending on the classification criterion, some algorithms are more efficient than others. Through our article, we classify plants according to their type: tree...

Malaria continues to be a major public health concern with a substantial burden in Africa. Even though it has been widely demonstrated that malaria transmission is climate-driven, there have been very few studies assessing the relationship between climate variables and malaria transmission in Côte d’Ivoire. We used the VECTRI model to predict malaria transmission in southern Côte d’Ivoire. First, we tested the suitability of VECTRI in modeling malaria transmission using ERA5 temperature data and ARC2 rainfall data. We then used the projected climatic data pertaining to 2030, 2050, and 2080 fro...

AbstractThis article presents a novel method for classification of plants using their leaves. Most plant species have unique leaves which differ from each other by characteristics such as the shape, colour, texture and the margin. The method introduced in this study proposes to use two of these features: the shape and the texture. The shape-based method will extract the contour signature from every leaf and then calculate the dissimilarities between them using the Jeffrey-divergence measure. The orientations of edge gradients will be used to analyse the macro-texture of the leaf. The results o...

The present study carried out in the Highest Bandama watershed at Tortiya, in the northern of Côte d'Ivoire, aims to evaluate climate variability impact on groundwater resources in order to best management. It is based on rainfall and runoff data exploitation. Thus, application of low-pass filter of Hanning and statistic tests (Pettitt, Lee and Heghinian) shows a rainfall regime modification occurred around the seventies years. This modification reveals a decrease of rainfall between 12% and 22% according the stations, with an average of 16.5%. This decrease is very high for runoff (62.5%) at...

Context: Hyptis suaveolens (L.) Poit; (Lamiaceae) is an aromatic plant whose leaves contain essential oils (less than 1%) and also non-volatile bio-active substances (More than 8%).

The aim of this study was to contribute to the development of tilapia aquaculture in Côte d’Ivoire by increasing the productivity of Oreochromis niloticus fry in fish hatcheries. Thus, the production of Oreochromis niloticus larvae was compared between two tilapia breeding systems, earthen ponds and hapas in ponds. Over 98 days, 900 broodstock fish were allowed to reproduce in two ponds of 500 m2 and 900 others in 20 hapas of 50 m2, each installed in two ponds of 1200 m2. The sex ratio was one male for two females at a density of 0.9 breeders/m2 at a density of 450 breeders per pond and 45 bre...

Chemical variability of a plant from various continents or collected in different localities justifies its different biological activities. Thus, the present study was undertaken to evaluate the statistical study of chemical variability of essential oils from leaves of Lippia multiflora Mold from five localities in the center of Côte d'Ivoire. Essential oils have been extracted by hydrodistillation with yields varying from 0.34 to 1.20% depending on localities. Analysis of their chemical compositions showed the predominance of eucalyptol / germacrene D (13.91 / 11.02%), α-citral / β-citral / α...
