price. In this work, biowaste of animal (sardines) and plant (tomato) biowaste was used to formulate a new feed for red tilapia that showed to be competitive in its price, and zootechnical performance in comparison to commercially available tilapia feeds. Mathematical modelling was used to formulate optimal feed composition with favorable chemical composition and the lowest price. Formulated feed had high protein content (40.76%) and an energy value of 279.6 Kcal/100 g. Optimised feed was manufactured and compared to commercially available reference feed with respect to feeding intake, feed efficiency, the specific growth rate of fingerlings of Tilapia sp, and, most important, zootechnical parameters. With a fish survival rate of 100% calculated feed conversion index for the formulated feed was 2.7. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conversion%20index" title="conversion index">conversion index</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20waste" title=" fish waste"> fish waste</a>, <a href="https://publications.waset.org/abstracts/search?q=formulated%20feed" title=" formulated feed"> formulated feed</a>, <a href="https://publications.waset.org/abstracts/search?q=tomato%20waste" title=" tomato waste"> tomato waste</a> </p> <a href="https://publications.waset.org/abstracts/157767/valorization-of-by-products-through-feed-formulation-for-tilapia-sp-zootechnical-performance-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157767.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Hydrodynamic Study and Sizing of a Distillation Column by HYSYS Software</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Derrouazin%20Mohammed%20Redhouane">Derrouazin Mohammed Redhouane</a>, <a href="https://publications.waset.org/abstracts/search?q=Souakri%20Mohammed%20Lotfi"> Souakri Mohammed Lotfi</a>, <a href="https://publications.waset.org/abstracts/search?q=Henini%20Ghania"> Henini Ghania</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work consists, first of all, of mastering one of the powerful process simulation tools currently used in the industrial processes, which is the HYSYS sizing software, and second, of simulating a petroleum distillation column. This study is divided into two parts; where the first one consists of a dimensioning of the column with a fast approximating method using state equations, iterative calculations, and then a precise simulation method with the HYSYS software. The second part of this study is a hydrodynamic study in order to verify by obtained results the proper functioning of the plates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=industry%20process%20engineering" title="industry process engineering">industry process engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20distillation" title=" water distillation"> water distillation</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=HYSYS%20simulation%20tool" title=" HYSYS simulation tool"> HYSYS simulation tool</a> </p> <a href="https://publications.waset.org/abstracts/154967/hydrodynamic-study-and-sizing-of-a-distillation-column-by-hysys-software" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154967.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">129</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Statistical Modeling and by Artificial Neural Networks of Suspended Sediment Mina River Watershed at Wadi El-Abtal Gauging Station (Northern Algeria)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Redhouane%20Ghernaout">Redhouane Ghernaout</a>, <a href="https://publications.waset.org/abstracts/search?q=Amira%20Fredj"> Amira Fredj</a>, <a href="https://publications.waset.org/abstracts/search?q=Boualem%20Remini"> Boualem Remini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Suspended sediment transport is a serious problem worldwide, but it is much more worrying in certain regions of the world, as is the case in the Maghreb and more particularly in Algeria. It continues to take disturbing proportions in Northern Algeria due to the variability of rains in time and in space and constant deterioration of vegetation. Its prediction is essential in order to identify its intensity and define the necessary actions for its reduction. The purpose of this study is to analyze the concentration data of suspended sediment measured at Wadi El-Abtal Hydrometric Station. It also aims to find and highlight regressive power relationships, which can explain the suspended solid flow by the measured liquid flow. The study strives to find models of artificial neural networks linking the flow, month and precipitation parameters with solid flow. The obtained results show that the power function of the solid transport rating curve and the models of artificial neural networks are appropriate methods for analysing and estimating suspended sediment transport in Wadi Mina at Wadi El-Abtal Hydrometric Station. They made it possible to identify in a fairly conclusive manner the model of neural networks with four input parameters: the liquid flow Q, the month and the daily precipitation measured at the representative stations (Frenda 013002 and Ain El-Hadid 013004 ) of the watershed. The model thus obtained makes it possible to estimate the daily solid flows (interpolate and extrapolate) even beyond the period of observation of solid flows (1985/86 to 1999/00), given the availability of the average daily liquid flows and daily precipitation since 1953/1954. <p class="card-text"><strong>Keywords:</strong> <a
