The changes occurring in the market business are often due to the variations of demand, which requires a very specific supply chain strategy. Supply chains aims to balance cost, quality, and service level and lead time. Still, managers are confused when faced with the strategies working the best for the supply chain: lean, agile and leagile. This paper presents a decision making tool that aims to assist the manager in choosing the supply chain strategy that suits the most his business, depending on the type of product and the nature of demand. Analyzing the different characteristics of supply chain will enable us to guide the manager to the suitable strategy between lean, agile and leagile. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=supply%20chain" title="supply chain">supply chain</a>, <a href="https://publications.waset.org/abstracts/search?q=lean" title=" lean"> lean</a>, <a href="https://publications.waset.org/abstracts/search?q=agile" title=" agile"> agile</a>, <a href="https://publications.waset.org/abstracts/search?q=flexibility" title=" flexibility"> flexibility</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a> </p> <a href="https://publications.waset.org/abstracts/29465/toward-a-new-approach-for-modeling-lean-agile-and-leagile-supply-chains" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29465.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">859</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">8</span> Circuit Models for Conducted Susceptibility Analyses of Multiconductor Shielded Cables</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saih%20Mohamed">Saih Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Rouijaa%20Hicham"> Rouijaa Hicham</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghammaz%20Abdelilah"> Ghammaz Abdelilah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents circuit models to analyze the conducted susceptibility of multiconductor shielded cables in frequency domains using Branin’s method, which is referred to as the method of characteristics. These models, Which can be used directly in the time and frequency domains, take into account the presence of both the transfer impedance and admittance. The conducted susceptibility is studied by using an injection current on the cable shield as the source. Two examples are studied, a coaxial shielded cable and shielded cables with two parallel wires (i.e., twinax cables). This shield has an asymmetry (one slot on the side).

In Morocco, as everywhere in the world, especially in developing countries, the therapeutic indications of medicinal plants are very present to treat several diseases, including the respiratory system. The objective of our study is to identify and document medicinal plants used in traditional medicine to treat viral respiratory infections and alleviate their symptoms in order to generate interest for future studies in verifying the efficacy of these traditional medicines and their conservation. The information acquired from 81 questionnaires and the floristic identification allowed us to identify 19 spontaneous species belonging to 11 families, used as traditional therapies for viral respiratory diseases in the Prerif. The herbs are the most used life form. The results also showed that leaves were the most commonly used plant parts and most of the herbal medicines were prepared in the form of infusions and administered orally. Documented data was evaluated using use value (UV), family importance value (FIV) and relative frequency citation (RCF). <p class="card-text"><strong>Keywords:</strong> <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=ethnobotanical" title=" ethnobotanical"> ethnobotanical</a>, <a href="https://publications.waset.org/abstracts/search?q=ethnopharmacological" title=" ethnopharmacological"> ethnopharmacological</a>, <a href="https://publications.waset.org/abstracts/search?q=viral%20respiratory%20diseases" title=" viral respiratory diseases"> viral respiratory diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=Morocco" title=" Morocco"> Morocco</a> </p> <a href="https://publications.waset.org/abstracts/142327/ethnobotanical-study-of-spontaneous-medicinal-plants-used-in-the-treatment-of-viral-respiratory-diseases-in-the-prerif-morocco" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142327.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">193</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">6</span> Tranexamic Acid in Orthopedic Surgery in Children</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Amanzoui">K.

Chlilek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Orthopedic surgery is a provider of pre and postoperative bleeding; patients are exposed to several risks, and different measures are proposed to reduce bleeding during surgery, called the transfusion-sparing method, including tranexamic acid, which has shown its effectiveness in numerous studies. A prospective analytical study in 50 children was carried out in the orthopedic traumatology operating room of the EL HAROUCHI hospital of the CHU IBN ROCHD in Casablanca over a period of six months (April to October 2022). Two groups were randomized: one receiving tranexamic acid (Group A) and a non-receiving control group (Group B). The average age was 10.3 years, of which 58.8% were female. The first type of surgery was thoracolumbar scoliosis (52%). The average preoperative hemoglobin was 12.28 g/dl in group A, against 12.67 g/dl in the control group. There was no significant difference between the two groups (p=0.148). Mean intraoperative bleeding was 396.29 ml in group A versus 412 ml in the control group. No significant difference was observed for this parameter (p=0.632). The average hemoglobin level in the immediate postoperative period in our patients is 10.2 g/dl. In group A, it was 10.95 g/dl versus 10.93 g/dl in group B. At H24 postoperative, the mean hemoglobin value was 10.29 g/dl in group A against 9.5 g/dl in group B. For group A, the blood loss recorded during the first 24 hours was 209.43 ml, against 372 ml in group B, with a significant difference between the two groups (p=0.001). There is no statistically significant difference between the 2 groups in terms of the use of fillers, ephedrine or intraoperative transfusion. While for postoperative transfusion, we note the existence of a statistically significant difference between group A and group B. It is suggested that the use of tranexamic acid is an effective, simple, and low-cost way to limit postoperative blood loss and the need for transfusion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tranexamic%20acid" title="tranexamic acid">tranexamic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=blood%20loss" title=" blood loss"> blood loss</a>, <a href="https://publications.waset.org/abstracts/search?q=orthopedic%20surgery" title=" orthopedic surgery"> orthopedic surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=children" title=" children"> children</a> </p> <a href="https://publications.waset.org/abstracts/162335/tranexamic-acid-in-orthopedic-surgery-in-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162335.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">68</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">5</span> Assessment of Sleep Disorders in Moroccan Women with Gynecological Cancer: Cross-Sectional Study </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amina%20Aquil">Amina Aquil</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdeljalil%20El%20Got"> Abdeljalil El Got</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Sleep quality is one of the most important indicators related to the quality of life of patients suffering from cancer. Many factors could affect this quality of sleep and then be considered as associated predictors. Methods: The aim of this study was to assess the prevalence of sleep disorders and the associated factors with impaired sleep quality in Moroccan women with gynecological cancer. A cross-sectional study was carried out within the oncology department of the Ibn Rochd University Hospital, Casablanca, on Moroccan women who had undergone radical surgery for gynecological cancer (n=100). Translated and validated Arabic versions of the following international scales were used: Pittsburgh sleep quality index (PSQI), Hospital Anxiety and Depression Scale (HADS), Rosenberg's self-esteem scale (RSES), and Body image scale (BIS). Results: 78% of participants were considered poor sleepers. Most of the patients exhibited very poor subjective quality, low sleep latency, a short period of sleep, and a low rate of usual sleep efficiency. The vast majority of these patients were in poor shape during the day and did not use sleep medication. Waking up in the middle of the night or early in the morning and getting up to use the bathroom were the main reasons for poor sleep quality. PSQI scores were positively correlated with anxiety, depression, body image dissatisfaction, and lower self-esteem (p < 0.001). Conclusion: Sleep quality and its predictors require a systematic evaluation and adequate management to prevent sleep disturbances and mental distress as well as to improve the quality of life of these patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=body%20image" title="body image">body image</a>, <a href="https://publications.waset.org/abstracts/search?q=gynecological%20cancer" title=" gynecological cancer"> gynecological cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=self%20esteem" title=" self esteem"> self esteem</a>, <a href="https://publications.waset.org/abstracts/search?q=sleep%20quality" title=" sleep quality"> sleep quality</a> </p> <a href="https://publications.waset.org/abstracts/131135/assessment-of-sleep-disorders-in-moroccan-women-with-gynecological-cancer-cross-sectional-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131135.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">123</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">4</span> Numerical Study of Natural Convection Heat Transfer in a Two-Dimensional Vertical Conical PartiallyAnnular Space</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Belkacem%20Ould%20Said">Belkacem Ould Said</a>, <a href="https://publications.waset.org/abstracts/search?q=Nourddine%20Retiel"> Nourddine Retiel</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelilah%20Benazza"> Abdelilah Benazza</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Aichouni"> Mohamed Aichouni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a numerical study of two-dimensional steady flow has been made of natural convection in a differentially heated vertical conical partially annular space. The heat transfer is assumed to take place by natural convection. The inner and outer surfaces of annulus are maintained at uniform wall temperature. The annulus is filled with air. The CFD FLUENT12.0 code is used to solve the governing equations of mass, momentum and energy using constant properties and the Boussinesq approximation for density variation. The streamlines and the isotherms of the fluid are presented for different annuli with different boundary conditions and Rayleigh numbers. Emphasis is placed on the influences of the height of the inner vertical cone on the flow and the temperature fields. In addition, the effects on the heat transfer are discussed for various values of physical parameters of the fluid and geometric parameters of the annulus. The heat transfer on the hot walls of the annulus is also calculated in order to make comparisons between the cylinder annulus for boundary conditions and several Rayleigh numbers. A good agreement of Nusselt number has been found between the present predictions and reference from the literature data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=natural%20convection" title="natural convection">natural convection</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title=" heat transfer"> heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=conical%20partially" title=" conical partially"> conical partially</a>, <a href="https://publications.waset.org/abstracts/search?q=annular%20space" title=" annular space"> annular space</a> </p> <a href="https://publications.waset.org/abstracts/1602/numerical-study-of-natural-convection-heat-transfer-in-a-two-dimensional-vertical-conical-partiallyannular-space" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1602.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">314</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> Tocilizumab Suppresses the Pro-carcinogenic Effects of Breast Cancer-associated Fibroblasts Through Inhibition of the STAT3/AUF1 Pathway</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naif%20Al-Jomah">Naif Al-Jomah</a>, <a href="https://publications.waset.org/abstracts/search?q=Falah%20H%20Al-Mohanna"> Falah H Al-Mohanna</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelilah%20Aboussekhra"> Abdelilah Aboussekhra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Active breast cancer-associated fibroblasts (CAFs), the most influential cells in breast tumor microenvironment, express/secrete high levels of the proinvasive/metastatic interleukin-6 (IL-6). Therefore, we have tested here the effect of the IL-6 receptor (IL-6R) inhibitor tocilizumab (TCZ; Actemra) on different active breast CAFs. We have shown that TCZ potently and persistently suppresses the expression of various CAF biomarkers, namely α-SMA, SDF-1 as well as the STAT3 pathway and its downstream target AUF1. TCZ also inhibited the proliferation, migration and invasion abilities of active breast CAF cells. Additionally, TCZ repressed the ability of CAF cells in promoting epithelial-to-mesenchymal transition, and enhancing the migratory/invasive and proliferative capacities of breast cancer cells in vitro. Importantly, these findings were confirmed in orthotopic humanized breast tumors in mice. Furthermore, TCZ suppressed the expression of the pro-angiogenic factor VEGF-A and its transactivator HIF-1α in CAF cells, and consequently inhibited the angiogenic-promoting effect of active CAFs both in vitro and in orthotopic tumor xenografts. These results indicate that inhibition of the IL-6/STAT3/AUF1 pathway by TCZ can normalize active breast CAFs and suppress their paracrine pro-carcinogenic effects, which paves the way toward development of specific CAF-targeting therapy, badly needed for more efficient breast cancer treatments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=angiogenesis" title="angiogenesis">angiogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=interleukin-6" title=" interleukin-6"> interleukin-6</a>, <a href="https://publications.waset.org/abstracts/search?q=paracrine" title=" paracrine"> paracrine</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer-associated%20fibroblasts" title=" cancer-associated fibroblasts"> cancer-associated fibroblasts</a> </p> <a href="https://publications.waset.org/abstracts/154395/tocilizumab-suppresses-the-pro-carcinogenic-effects-of-breast-cancer-associated-fibroblasts-through-inhibition-of-the-stat3auf1-pathway" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154395.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">97</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> Estimation of Natural Pozzolan Reserves in the Volcanic Province of the Moroccan Middle Atlas Using a Geographic Information System in Order to Valorize Them</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brahim%20Balizi">Brahim Balizi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayoub%20Aziz"> Ayoub Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelilah%20Bellil"> Abdelilah Bellil</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdellali%20El%20Khadiri"> Abdellali El Khadiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamal%20Mabrouki"> Jamal Mabrouki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mio-polio-quaternary volcanism of the Tabular Middle Atlas, which corresponds to prospective levels of exploitable usable raw minerals, is a feature of Morocco's Middle Atlas, especially the Azrou-Timahdite region. Given their importance in national policy in terms of human development by supporting the sociological and economic component, this area has consequently been the focus of various research and prospecting of these levels in order to develop these reserves. The outcome of this labor is a massive amount of data that needs to be managed appropriately because it comes from multiple sources and formats, including side points, contour lines, geology, hydrogeology, hydrology, geological and topographical maps, satellite photos, and more. In this regard, putting in place a Geographic Information System (GIS) is essential to be able to offer a side plan that makes it possible to see the most recent topography of the area being exploited, to compute the volume of exploitation that occurs every day, and to make decisions with the fewest possible restrictions in order to use the reserves for the realization of ecological light mortars The three sites' mining will follow the contour lines in five steps that are six meters high and decline. It is anticipated that each quarry produces about 90,000 m3/year. For a single quarry, this translates to a daily production of about 450 m3 (200 days/year). About 3,540,240 m3 and 10,620,720 m3, respectively, represent the possible net exploitable volume in place for a single quarry and the three exploitable zones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GIS" title="GIS">GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=topography" title=" topography"> topography</a>, <a href="https://publications.waset.org/abstracts/search?q=exploitation" title=" exploitation"> exploitation</a>, <a href="https://publications.waset.org/abstracts/search?q=quarrying" title=" quarrying"> quarrying</a>, <a href="https://publications.waset.org/abstracts/search?q=lightweight%20mortar" title=" lightweight mortar"> lightweight mortar</a> </p> <a href="https://publications.waset.org/abstracts/190234/estimation-of-natural-pozzolan-reserves-in-the-volcanic-province-of-the-moroccan-middle-atlas-using-a-geographic-information-system-in-order-to-valorize-them" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190234.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">26</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> Mycorrhizal Autochthonous Consortium Induced Defense-Related Mechanisms of Olive Trees against Verticillium dahliae</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hanane%20Boutaj">Hanane Boutaj</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelilah%20Meddich"> Abdelilah Meddich</a>, <a href="https://publications.waset.org/abstracts/search?q=Said%20Wahbi"> Said Wahbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Zainab%20El%20Alaoui-Talibi"> Zainab El Alaoui-Talibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Allal%20Douira"> Allal Douira</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelkarim%20Filali-Maltouf"> Abdelkarim Filali-Maltouf</a>, <a href="https://publications.waset.org/abstracts/search?q=Cherkaoui%20El%20Modafar"> Cherkaoui El Modafar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present work aims to investigate the effect of arbuscular mycorrhizal fungi (AMF) in improving the olive tree resistance to Verticillium wilt caused by Verticillium dahliae. Inoculated plants with a mycorrhizal autochthonous consortium 'Rhizolive consortium' and pure strain 'Glomus irregulare' were infected after three months with V. dahliae. The improving of olive tree resistance was determined through disease severity, incidence, and defoliation. On the other hand, the defense mechanisms of olive plants were evaluated through lignin content, phenylalanine ammonia lyase (PAL) activity, and polyphenol content. The results revealed that both AMF significantly (p < 0.05) reduced disease development and the rate of defoliation in infected olive plants. Moreover, the contents of lignin were boosted after mycorrhizal inoculation in both the roots and the stems of olive plants, which remained significantly (p < 0.001) higher after the 90th days of V. dahliae inoculation. PAL activity was increased after V. dahliae inoculation in the stems of 'Rhizolive consortium' treatment that were 17 times higher than those in the roots of olive plants. The polyphenol content in the stems was about twice higher than those in the roots. The reduction of disease severity was accompanied by increased levels of lignin content, PAL activity, and polyphenol content, particularly in the stems of olive plants, indicating the strengthening of the olive plant immune system against V. dahliae. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=olive%20tree" title="olive tree">olive
