Although efforts have been made in the field of sanitation in urban areas, rural areas, due to their specificities, such as scattered dwellings and limited accessibility, suffer from a lack of basic infrastructure. This work focuses on replicating the Faculty of Sciences Ain Chock (FSAC) model for the treatment and reuse of wastewater from a peri-urban traditional hammam in Casablanca, specifically in the municipality of Dar Bouazza. This initiative is part of the Eco-Hammam project, which aims to minimize the negative impacts of traditional hammams in terms of irrational and uncontrolled consumption of water and wood energy resources. To achieve this, a comprehensive environmental diagnosis of all hammams in the municipality of Dar Bouazza, our study site, has been undertaken. Then, a feasibility study is also conducted to assess the possibility of replicating the FSAC mini-station to treat the wastewater of the selected pilot hammam, namely, My Yacoub II. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20resource%20scarcity" title="water resource scarcity">water resource scarcity</a>, <a href="https://publications.waset.org/abstracts/search?q=unconventional%20resources" title=" unconventional resources"> unconventional resources</a>, <a href="https://publications.waset.org/abstracts/search?q=sanitation" title=" sanitation"> sanitation</a>, <a href="https://publications.waset.org/abstracts/search?q=per-urban%20areas" title=" per-urban areas"> per-urban areas</a>, <a href="https://publications.waset.org/abstracts/search?q=rural%20areas" title=" rural areas"> rural areas</a>, <a href="https://publications.waset.org/abstracts/search?q=basic%20infrastructure" title=" basic infrastructure"> basic infrastructure</a>, <a href="https://publications.waset.org/abstracts/search?q=replication" title=" replication"> replication</a>, <a href="https://publications.waset.org/abstracts/search?q=reuse%20of%20wastewater" title=" reuse of wastewater"> reuse of wastewater</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20hammam" title=" traditional hammam"> traditional hammam</a>, <a href="https://publications.waset.org/abstracts/search?q=Casablanca" title=" Casablanca"> Casablanca</a>, <a href="https://publications.waset.org/abstracts/search?q=Municipality%20of%20Dar%20Bouazza" title=" Municipality of Dar Bouazza"> Municipality of Dar Bouazza</a>, <a href="https://publications.waset.org/abstracts/search?q=negative%20impacts" title=" negative impacts"> negative impacts</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20diagnosis" title=" environmental diagnosis"> environmental diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=feasibility%20study" title=" feasibility study"> feasibility study</a>, <a href="https://publications.waset.org/abstracts/search?q=pilot%20hammam" title=" pilot hammam"> pilot hammam</a>, <a href="https://publications.waset.org/abstracts/search?q=My%20Yacoub%20II" title=" My Yacoub II"> My Yacoub II</a> </p> <a href="https://publications.waset.org/abstracts/176379/eco-hammam-initiative-replicating-the-fsac-model-for-sustainable-wastewater-treatment-and-resource-reuse-in-dar-bouazza-morocco" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176379.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">63</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">26</span> Thermal Effect in Power Electrical for HEMTs Devices with InAlN/GaN</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zakarya%20Kourdi">Zakarya Kourdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Khaouani"> Mohammed Khaouani</a>, <a href="https://publications.waset.org/abstracts/search?q=Benyounes%20Bouazza"> Benyounes Bouazza</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahlam%20Guen-Bouazza"> Ahlam Guen-Bouazza</a>, <a href="https://publications.waset.org/abstracts/search?q=Amine%20Boursali"> Amine Boursali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we have evaluated the thermal effect for high electron mobility transistors (HEMTs) heterostructure InAlN/GaN with a gate length 30nm high-performance.

With the reduction of dimensions of components at 0.1 micron and below, new physical effects come into play as the standard simulators of two dimensions (2D) do not consider. In fact the third dimension comes into play because the transverse and longitudinal dimensions of the components are of the same order of magnitude. To describe the operation of such components with greater fidelity, we must refine simulation tools and adapted to take into account these phenomena. After an analytical study of the static characteristics of the component, according to the different operating modes, a numerical simulation is performed of field-effect transistor with submicron gate MESFET GaInP. The influence of the dimensions of the gate length is studied. The results are used to determine the optimal geometric and physical parameters of the component for their specific applications and uses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monte%20Carlo%20simulation" title="Monte Carlo simulation">Monte Carlo simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=transient%20electron%20transport" title=" transient electron transport"> transient electron transport</a>, <a href="https://publications.waset.org/abstracts/search?q=MESFET%20device" title=" MESFET device"> MESFET device</a>, <a href="https://publications.waset.org/abstracts/search?q=GaInP" title=" GaInP"> GaInP</a> </p> <a href="https://publications.waset.org/abstracts/19250/modeling-the-transport-of-charge-carriers-in-the-active-devices-mesfet-based-of-gainp-by-the-monte-carlo-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19250.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">419</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">22</span> 3D Quantum Simulation of a HEMT Device Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Z.%20Kourdi">Z.

This work demonstrates the optimal device with a gate length of 15 nm, InAlN/GaN heterostructure and field plate structure, making it superior to modern HEMTs when compared with otherwise equivalent devices. This improves the ability to bear the burden of the current density passes in the channel. We have demonstrated an excellent current density, as high as 2.05 A/mm, a peak extrinsic transconductance of 590 mS/mm at VDS=2 V, and cutting frequency cutoffs of 638 GHz in the first HEMT and 463 GHz for Field plate HEMT., maximum frequency of 1.7 THz, maximum efficiency of 73%, maximum breakdown voltage of 400 V, DIBL=33.52 mV/V and an ON/OFF current density ratio higher than 1 x 1010.

Urbanization in Morocco has led to a significant increase in the number of these traditional hammams: between 6,000 and 15,000 units (to be updated) operate with a traditional heating system. Numerous studies on energy consumption indicate that a hammam consumes between 60 and 120m3 of water and one to two tons of wood per day. On average, one ton of wood costs 650 Moroccan dirhams (approximately 60 Euros), resulting in a daily fuel cost of around 1300 Moroccan dirhams (about 120 Euros). These high consumptions result in significant environmental nuisances generated by: Wastewater: in the case of hammams located on the outskirts of Casablanca, such as our study area, the Municipality of Dar Bouazza, most of these waters are directly discharged into the receiving environment without prior treatment because they are not connected to the sanitation network. Emissions of black smoke and ashes produced by the often incomplete combustion of wood. Reducing the liquid and gas emissions generated by these hammams thus poses an environmental and sustainable development challenge that needs to be addressed. In this context, we initiated the Eco-hammam project with the objective of implementing innovative and locally adapted solutions to limit the negative impacts of hammams on the environment and reduce water and wood energy consumption. This involves treating and reusing wastewater through a compact system with heat recovery and using alternative energy sources to increase and enhance the energy efficiency of these traditional hammams. To achieve this, on-site surveys of hammams in the Dar Bouazza Municipality and the application of statistical approaches to the results of the physico-chemical and bacteriological characterization of incoming and outgoing water from these units were conducted. This allowed us to establish an environmental diagnosis of these entities. In conclusion, the analysis of well water used by Dar Bouazza's hammams revealed the presence of certain parameters that could be hazardous to public health, such as total germs, total coliforms, sulfite-reducing spores, chromium, nickel, and nitrates. Therefore, this work primarily focuses on prospecting upstream of our study area to verify if other sources of pollution influence the quality of well water. <p

As the oxide thickness scales below 2 nm, leakage currents due to tunneling increase drastically, leading to high power consumption and reduced device reliability. Replacing the SiO2 gate oxide with a high-κ material allows increased gate capacitance without the associated leakage effects. In this paper, SOI TRI-GATE FinFET structure with use of high K dielectric materials (HfO2) and SiO2 dielectric are simulated using the 3-D device simulator Devedit and Atlas of TCAD Silvaco. The simulated results exhibits significant improvements in the performances of SOI TRI GATE FinFET with gate oxide HfO2 compared with conventional gate oxide SiO2 for the same structure. SOI TRI-GATE FinFET structure with the use of high K materials (HfO2) in gate oxide results into the increase in saturation current, threshold voltage, on-state current and Ion/Ioff ratio while off-state current, subthreshold slope and DIBL effect are decreased. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=technology%20SOI" title="technology SOI">technology SOI</a>, <a href="https://publications.waset.org/abstracts/search?q=short-channel%20effects%20%28SCEs%29" title=" short-channel effects (SCEs)"> short-channel effects (SCEs)</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-gate%20SOI%20MOSFET" title=" multi-gate SOI MOSFET"> multi-gate SOI MOSFET</a>, <a href="https://publications.waset.org/abstracts/search?q=SOI-TRI%20Gate%20FinFET" title=" SOI-TRI Gate FinFET"> SOI-TRI Gate FinFET</a>, <a href="https://publications.waset.org/abstracts/search?q=high-K%20dielectric" title=" high-K dielectric"> high-K dielectric</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvaco%20software" title=" Silvaco software"> Silvaco software</a> </p> <a href="https://publications.waset.org/abstracts/31441/performance-improvement-of-soi-tri-gate-finfet-transistor-using-high-k-dielectric-with-metal-gate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31441.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">347</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">19</span> High Performance of Square GAA SOI MOSFET Using High-k Dielectric with Metal Gate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Zohra%20Rahou">Fatima Zohra Rahou</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Guen%20Bouazza"> A.

Based on sum of product terms (PTs) architecture, the PLD/CPLD offer a high degree of flexibility to support various application requirements. They are suitable for large combinational logic, finite state machines as well as intensive I/O designs. CPLDs offer very predictable timing characteristics and are therefore ideal for critical control applications. This paper describes how the logic synthesis techniques, such as 1) XOR detection, 2) logic doubling, 3) complement of a Boolean function are combined, applied and used to optimize the CPLDs devices architecture that is based on PAL-like macrocells. Our goal is to use these techniques for minimizing the number of macrocells required to implement a circuit and minimize the delay of mapped circuit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CPLD" title="CPLD">CPLD</a>, <a href="https://publications.waset.org/abstracts/search?q=doubling" title=" doubling"> doubling</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=XOR" title=" XOR"> XOR</a> </p> <a href="https://publications.waset.org/abstracts/8359/intelligent-and-optimized-placement-for-cpld-devices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8359.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">282</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">16</span> Buckling Behavior of FGM Plates Using a Simplified Shear Deformation Theory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mokhtar%20Bouazza">Mokhtar Bouazza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the simplified theory will be used to predict the thermoelastic buckling behavior of rectangular functionally graded plates.

Our work is dedicated to the comparative analysis of the groupings in chamaeropaie of the mounts of Tlemcen and mounts of traras, based on a phytoécologique approach. Four representative stations of chamaeropaies were retained to make this work. 120 floristic surveys were realized by using a minimal area of 100 m2. The obtained results show that the Mounts of Tlemcen present a wealth more important than those met at the level of the Mounts of Traras. More we go away from the coast towards the Mounts of Tlemcen, we notice a regressive evolution and a transformation of the plant carpet towards a thérophytisation, as well as an accentuation of the aridity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tlemcen" title="Tlemcen">Tlemcen</a>, <a href="https://publications.waset.org/abstracts/search?q=west%20Algeria" title=" west Algeria"> west Algeria</a>, <a href="https://publications.waset.org/abstracts/search?q=Chamaerops%20humilis%20L." title=" Chamaerops humilis L."> Chamaerops humilis L.</a>, <a href="https://publications.waset.org/abstracts/search?q=phyto%C3%A9cological" title=" phytoécological"> phytoécological</a>, <a href="https://publications.waset.org/abstracts/search?q=floristic%20survey" title=" floristic survey"> floristic survey</a>, <a href="https://publications.waset.org/abstracts/search?q=th%C3%A9rophytisation" title=" thérophytisation"> thérophytisation</a> </p> <a href="https://publications.waset.org/abstracts/34223/dynamics-of-plant-communities-with-chamaerops-humilis-in-the-region-of-tlemcen" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34223.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">283</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">11</span> Zero Cross-Correlation Codes Based on Balanced Incomplete Block Design: Performance Analysis and Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Garadi%20Ahmed">Garadi Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Boubakar%20S.%20Bouazza"> Boubakar S.

These wastes are up to two times saltier than standard seawater. Therefore, there is a strong economic interest in recovering these salts. The current practice in desalination plants is to reject the brine back to the sea, which affects the marine ecosystem and the environment. Our study aims to bring forth a reliable management solution for the valorisation of waste brines. Natural evaporation, isothermal evaporation at 25°C and 50°C, and evaporation using continuous heating were used to crystallize valuable salts from a reverse osmosis desalination plant brine located on the Moroccan Atlantic coast. The crystallization sequence of the brine was studied in comparison with standard seawater. The X-Ray Diffraction (XRD) of the precipitated solid phases showed similar results, where halite was the main solid phase precipitated from both the brine and seawater. However, Jänecke diagram prediction, along with FREZCHEM simulations, showed that Kainite should crystallize before Epsomite and Carnallite. As the absence of kainite formation in many experiments in the literature has been related to the metastability of kainite and the critical relative humidity conditions, and the precipitation of K–Mg salts is very sensitive to climatic conditions. An evaporation process is proposed as a solution to achieve the predicted crystallization path and to affirm the recovery of Kainite. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=salts%20crystallization" title="salts crystallization">salts crystallization</a>, <a href="https://publications.waset.org/abstracts/search?q=reverse%20osmosis" title=" reverse osmosis"> reverse osmosis</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20evaporation" title=" solar evaporation"> solar evaporation</a>, <a href="https://publications.waset.org/abstracts/search?q=frezchem" title=" frezchem"> frezchem</a>, <a href="https://publications.waset.org/abstracts/search?q=ZLD" title=" ZLD"> ZLD</a> </p> <a href="https://publications.waset.org/abstracts/162012/valorization-of-waste-reverse-osmosis-desalination-brine-and-crystallization-sequence-approach-for-kainite-recovery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162012.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">103</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">3</span> Some Codes for Variants in Graphs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sofia%20Ait%20Bouazza">Sofia Ait Bouazza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We consider the problem of finding a minimum identifying code in a graph. This problem was initially introduced in 1998 and has been since fundamentally connected to a wide range of applications (fault diagnosis, location detection …). Suppose we have a building into which we need to place fire alarms. Suppose each alarm is designed so that it can detect any fire that starts either in the room in which it is located or in any room that shares a doorway with the room. We want to detect any fire that may occur or use the alarms which are sounding to not only to not only detect any fire but be able to tell exactly where the fire is located in the building. For reasons of cost, we want to use as few alarms as necessary. The first problem involves finding a minimum domination set of a graph. If the alarms are three state alarms capable of distinguishing between a fire in the same room as the alarm and a fire in an adjacent room, we are trying to find a minimum locating domination set. If the alarms are two state alarms that can only sound if there is a fire somewhere nearby, we are looking for a differentiating domination set of a graph. These three areas are the subject of much active research; we primarily focus on the third problem. An identifying code of a graph G is a dominating set C such that every vertex x of G is distinguished from other vertices by the set of vertices in C that are at distance at most r≥1 from x. When only vertices out of the code are asked to be identified, we get the related concept of a locating dominating set. The problem of finding an identifying code (resp a locating dominating code) of minimum size is a NP-hard problem, even when the input graph belongs to a number of specific graph classes. Therefore, we study this problem in some restricted classes of undirected graphs like split graph, line graph and path in a directed graph. Then we present some results on the identifying code by giving an exact value of upper total locating domination and a total 2-identifying code in directed and undirected graph. Moreover we determine exact values of locating dominating code and edge identifying code of thin headless spider and locating dominating code of complete suns. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=identiying%20codes" title="identiying codes">identiying codes</a>, <a href="https://publications.waset.org/abstracts/search?q=locating%20dominating%20set" title=" locating dominating set"> locating dominating set</a>, <a href="https://publications.waset.org/abstracts/search?q=split%20graphs" title=" split graphs"> split graphs</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20headless%20spider" title=" thin headless spider"> thin headless spider</a> </p> <a href="https://publications.waset.org/abstracts/26380/some-codes-for-variants-in-graphs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26380.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">480</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> Antibiotic Resistance and Susceptibility of Bacteria Strains Isolated from Sheep Milk</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Bouazza">Fatima Bouazza</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachida%20Hassikou"> Rachida Hassikou</a>, <a href="https://publications.waset.org/abstracts/search?q=Lamiae%20Amallah"> Lamiae Amallah</a>, <a href="https://publications.waset.org/abstracts/search?q=Jihane%20Ennadir"> Jihane Ennadir</a>, <a href="https://publications.waset.org/abstracts/search?q=Khadija%20Khedid"> Khadija Khedid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study evaluated the in vitro resistance and susceptibility of Enterobacteriaceae (Escherichia coli and Klebsiella oxytoca strains) and Staphylococci strains, isolated from sheep’s milk, against antibiotics and essential oils from Thymus satureioides and Mentha pulegium. Antibiotic resistance tests were done using disc diffusion while essential oils were extracted by steam distillation, and yields were calculated relative to plant dry matter. Gas chromatography-mass Spectrometry (GC-MS) was used to analyze each oil's chemical composition. The AMC, CTX, FOX, NA, CN, CIP, and OFX were very effective against the E. coli strains tested. Half of the strains were resistant to AMC, 60% to TIC, and 80% to TE. The K. oxytoca was resistant against AMC, FOX, and TIC (100%). Antibiotic-resistant testing on Staphylococci strains indicated Staphylococcus capitis and Staphylococcus chromogenes as the most sensitive. Staphylococcus aureus, Staphylococcus xylosus, and Staphylococcus cohnii ureal exhibited less resistance to OX, TE, PT, E, and P. The M. pulegium resulted in a higher yield of essential oil of 3.2% oil compared to T. satureioides with only 1.85% yield. Staphylococcus aureus, Staphylococcus xylosus, and Staphylococcus cohnii ureal had lower OX, TE, PT, E, and P resistance. M. pulegium yielded 3.2% essential oil compared to 1.85% for T. satureioides. The monoterpene oxygenated derivatives, monoterpene hydrocarbons, and phenols are found in essential oil extracts. T. satureioides essential oil had high antibacterial activity even at low concentrations (0.2; 0.55 g/mL). The Minimal Bactericidal Concentration (MBC) values indicate that the essential oils from the plants analyzed had bactericidal effects on all strains tested and are similar to the Minimal Inhibitory Concentration (MIC) values. The high antibacterial properties of these medicinal plants, against bacteria isolated from sheep’s milk, provide an opportunity to use these medicinal plants in the breeding sector as additives and preservatives in the dairy industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibiotic%20resistance" title="antibiotic resistance">antibiotic resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=medicinal%20plants" title=" medicinal plants"> medicinal plants</a>, <a href="https://publications.waset.org/abstracts/search?q=essential%20oils" title=" essential oils"> essential oils</a>, <a href="https://publications.waset.org/abstracts/search?q=enterobacteriaceae" title=" enterobacteriaceae"> enterobacteriaceae</a>, <a href="https://publications.waset.org/abstracts/search?q=staphylococci" title=" staphylococci"> staphylococci</a>, <a href="https://publications.waset.org/abstracts/search?q=sheep%20milk" title=" sheep milk"> sheep milk</a> </p> <a href="https://publications.waset.org/abstracts/144395/antibiotic-resistance-and-susceptibility-of-bacteria-strains-isolated-from-sheep-milk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144395.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">160</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> Physico-Chemical and Biotechnological Characterization of Sheep’s Milk (Ovis aries) by Three Medicinal Plants Extracts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Bouazza">Fatima Bouazza</a>, <a href="https://publications.waset.org/abstracts/search?q=Khadija%20Khedid"> Khadija Khedid</a>, <a href="https://publications.waset.org/abstracts/search?q=Lamiae%20Amallah"> Lamiae Amallah</a>, <a href="https://publications.waset.org/abstracts/search?q=Aziz%20Mouhaddach"> Aziz Mouhaddach</a>, <a href="https://publications.waset.org/abstracts/search?q=Basma%20Boukour"> Basma Boukour</a>, <a href="https://publications.waset.org/abstracts/search?q=Jihane%20Ennadir"> Jihane Ennadir</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachida%20Hassikou"> Rachida Hassikou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to combine milk and its derived products conservation and flavoring, Moroccans often used aromatic and medicinal plants. These plant extracts are endowed with several nutritive and therapeutic properties. This study constitutes a first national assessment of physico-chemical quality of sheep’s milk from moroccan Sardi breed and the evaluation of the antibacterial effect of three medicinal plants extracts: Aloe barbadensis Miller, Thymus satureioides and Mentha pulegium on flora isolated from this sheep's milk. 100 milk samples were collected in four regions of Morocco. The bacteria isolated were identified by classical and molecular methods (16S rRNA sequencing) and tested, according to the disk method, for their sensitivity to several antibiotics. The physico-chemical analyzes of sheep’s milk concerned the pH, titratable acidity, density, dry extract, freezing point and contents of: fat, proteins, lactose and calcium. The essential oils (EOs) of T. satureioides and M .pulegium were extracted by hydrodistillation and analyzed by GC / MS, while the Aloe vera leaf pulp was analyzed by the methods of Harborne and HPLC. A total number of 125 bacteria have been identified. Significant resistance to chemical antibiotics has been noted in LABs. The average temperature value of milk is around 57.15 °C, the pH is 6.56, the titratable acidity is around 3.4 ° D, the density is 1.035g / cm³ , the total dry extract is around 169.5g / l, the ash (9.8g / l), the freezing point (- 0.556 °C) while the average fat content is 67.85g / l . The samples richest in fat belong to the region of Settat, cradle of the Sardi breed, with a maximum average value of 74.4g / l. The average protein is 56g / l, lactose (39.92g / l), and calcium (1.855g / l). Analysis of the major components of EOs revealed the dominance of borneol in the case of T. satureioides and of pulegone in M. pulegium. Aloe vera gel contains alkaloids, flavonoids, catechic tannins, saponins and 1.60 µg / ml of aloin. The plant extracts have a bactericidal effect on E. coli, Klebsiellaoxytoca and Staphylococci and bacteriostatic effect on LABs of technological interest (Lactobacillus). As a result of this study, it is believed that the consumption of sardi sheep’s milk would be of nutritional benefit. Its richness in fat and proteins predisposes it for biotechnological development in the manufacture of cheese and yogurt. Also, the use of aromatic and medicinal plants, as natural additives would be of great benefit to flavor and maintain its quality. <p class="card-text"><strong>Keywords:</strong> <a
