La valorisation du tourteau détoxiqué d’amandes d’hévéa (Hevea brasiliensis) (TH) et du tourteau d’amandes déclassées de cajou (Anacardium occidentale) (TA) dans l’alimentation animale a été étudiée chez les porcs croisés de 28 jours (sevrage) à 180 jours. Ces animaux, répartis au sevrage en cinq lots, ont reçu soit un régime témoin (RT), soit un des quatre régimes expérimentaux contenant 7,5 % ou 15 % de TH (TH7,5 et TH15) ou de TA (TA7,5 et TA15). Les croissances journalières ont été de 246 ± 26, 198 ± 41, 191 ± 31, 154 ± 20 et 153 ± 31 g.j-1 de 29 à 89 jours d’âge, et de 511 ± 84, 456 ± 74,...

Abstract The aging process of the insulating oils of an electrical transformer is initiated as soon as the transformer is put into service. The quality of these oils must therefore be rigorously evaluated to have reliable and exploitable data for decision‐making. In general, the decision is to continue monitoring, reclaiming/regenerating, or replacing the oil in extreme cases. Thus, early diagnosis of power transformer oils helps prevent potential breakdowns that could considerably impact the electrical energy transmission and distribution network. This research used an imaging technique calle...

La relation pluie-débit fait l'objet de nombreuses études, à cause de son importance dans la mise en œuvre de nombreux projets de développement. La communauté scientifique, dans le souci de faire face aux problèmes d'eau, tels que les inondations et les sècheresses, utilise différents modèles. Mais ces modèles sont généralement confrontés à la non-linéarité de la relation pluie-débit. Dans le cas du Bandama Blanc, objet de cette étude, cette non-linéarité est accentuée par la présence de plusieurs barrages à vocation agro-pastorale situés dans la partie nord de la zone d'étude et qui utilisent...

Soybean meal is the dominant protein source for poultry nutrition. However, soybean is not widely grown in Europe, necessitating importation from other countries. To reduce dependency on imported soybean meal, an alternative feed material is needed. Fermentation and/or germination of grains are known to increase the value of the protein content of a diet. This study aimed to determine if they could substitute partly soybean meal in a diet. Germinated or fermented or germinated and fermented grains of lupin and oats were used in laying hen’s diet (a mix of 6.50% lupin and 3.50% oat grains). Oat...

AbstractBuilding lighter but stronger has been a major industrial concern in recent decades. To achieve its goals, Altuglas International, a subsidiary of the Arkema group, has developed several types of nanostructured acrylic glass materials, that are lighter and more resistant than glass PMMA. Combining PMMA (polymethyl methacrylate) and a nanostructured elastomer, this material has perfect transparency and special mechanical properties. In addition to its automotive applications, its exceptional properties open up prospects in aeronautics and safety glazing. In the present study, different...

Abstract Iron-based nanoparticles were formed in the pores of a micro- and mesoporous activated carbon made from banana spike by the impregnation of iron sulfate at various ratios and further pyrolysis, in order to prepare three catalysts AC@Fe/1, AC@Fe/2, AC@Fe/3 having iron mass contents of 1.6%, 2.2% and 3.3%, respectively. The pore size distributions, transmission electron microscope observations and X-ray photoelectron spectroscopy analyses have revealed that iron-based nanoparticles of 1–50 nm diameter, containing O and P, are located mainly in the supermicropores and mesopores of the ac...

Cashew kernels provide fats, proteins, minerals and amino acids like soybeans. They are characterized by their richness in linoleic and oleic acids which respectively contribute up to 20% and 60% of the fat. The aim of the present study is to assess the impact of the diets of laying hens, based on of cashew nut kernels cakes, on the nutritional and sensory quality of eggs. To carry out the experiment, 20 weeks old, 96 hens of the LOHMAN-Brown strain and with an average weight of 1600 g, were used over a period of 10 weeks. Laying hens were fed four diets Rt, R10, R15 and R20 at incorporation r...

The sustainable management of waste generated by human activities is now a global concern. The valorization of waste by pyrolysis is a recycling method aiming at obtaining a biochar which can contribute to improve the fertility of soils and to limit the use of chemical fertilizers. It is in this perspective that the present study aims to valorize cassava peelings into biochar. Slow pyrolysis was applied for biochar production using an artisanal oven at 400 °C and the obtained biochar was characterized. FTIR analysis revealed that cassava peelings biochar consists of hydrophilic surface functio...

This study is based on the evaluation of the adsorption process using Corbula trigona shell powder to remove lead from aqueous solution in a batch mode. Different analytical techniques, including X-ray diffraction, Fourier transform infrared spectroscopy, and EDS-coupled scanning electron microscopy, were used to characterize the shell powder before and after lead treatment. Regarding the pollutant removal, a Plackett-Burman design (PBD) was first used to determine the influencing factors from the following experimental domain: solution pH (3-9), adsorbent mass (0.1-0.5 g), contact time (40 -2...

Methane and krypton adsorption measured on single-walled nanotubes at 78.7 and 77.3 K, respectively, give rise to stepwise isotherms, representative of the adsorption on two types of comparatively uniform patches during the first stages of the adsorbate condensation. The values of the methane isosteric heat of adsorption on these two fractions of quasi-uniform surface, determined from the dependence of the equilibrium pressure on temperature between 78 and 110 K, are in very good agreement with those measured at 77.3 K by means of isothermal microcalorimetry in quasi-equilibrium. Their respect...

Oil is a vital part of the transformer body and (similarly to blood in a human being body) keeps responsibility for the condition of the entire organism. Oil is particularly responsible for functional serviceability of the entire insulation system. The insulating oil must be kept in pristine condition, since its condition can be a decisive factor, which determines the life span of the transformer. Fields and laboratory experiences have shown that transformer oil contains a vast amount of information. Oil analyses can be extremely useful in monitoring the condition of power transformers.

Yam (Dioscorea spp) occupies an important place in the diet of the populations of Côte d’Ivoire. It is a real source of starch and therefore generates enormous commercial potential. However, the decrease in production due to pest attacks represents a real threat to this crop. This study was conducted with the aim of improving yam production in Côte d’Ivoire. To do so, isolations carried out on yam leaves showing symptoms of foliar diseases have allowed us to identify 9 fungal genera. These were Colletotrichum sp., Fusarium sp., Pestalotiopsis sp., Pestalotia sp., Botryodiplodia sp., Aspergillu...

In this paper, we present a self-stabilizing asynchronous distributed clustering algorithm that builds non-overlapping k-hops clusters. Our approach does not require any initialization. It is based only on information from neighboring nodes with periodic messages exchange. Starting from an arbitrary configuration, the network converges to a stable state after a finite number of steps. Firstly, we prove that the stabilization is reached after at most n+2 transitions and requires (u+1)* log(2n+k+3) bits per node, whereΔu represents node's degree, n is the number of network nodes and k represents...
