production in Algeria is fallow-wheat. This is an extensive system that meets only the half needs some cereals and fodder demand. Resorption of fallow has become a strategic necessity to ensure food security in response to the instability of supply and the persistence of higher food prices on the world market. Despite several attempts to replace the fallow by crop cultures, choosing the best crop remains. Today, the agronomic and economic interests of legumes are demonstrated. However, their crop culture remains marginalized because of the weakness and instability of their performance. In the context of improving legumes and cereals crops as well as fallow resorption, we undertook to test, in the field, the effect of rhizobial inoculation of Phaseolus vulgaris in association with Zea Mays. We firstly studied the genetic diversity of rhizobial strains that nodulate P.vulgaris isolated from fifteen (15) different regions. ARDRA had shown 18 different genetic profiles. Symbiotic characterization highlighted a strain that highly significantly improved the fresh and dry weight of the host plant, in comparison to the negative control (un-inoculated) and the positive control (inoculated with the reference strain CIAT 899). In the field, the selected strain increased significantly the growth and yield of P.vulgaris and Zea Mays comparing to the non-inoculated control. However, the mix inoculation (selected strain+ Ciat 899) had not given the best parameters showing, thus, no synergy between the strains. These results indicate the replacing fallow by a crop legume in intercropping with cereals crops. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fallow" title="fallow">fallow</a>, <a href="https://publications.waset.org/abstracts/search?q=intercropping" title=" intercropping"> intercropping</a>, <a href="https://publications.waset.org/abstracts/search?q=inoculation" title=" inoculation"> inoculation</a>, <a href="https://publications.waset.org/abstracts/search?q=legumes-cereals" title=" legumes-cereals"> legumes-cereals</a> </p> <a href="https://publications.waset.org/abstracts/44441/effect-of-phaseolus-vulgaris-inoculation-on-p-vulgaris-and-zea-mays-growth-and-yield-cultivated-in-intercropping" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44441.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">366</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">12</span> Improved of Elliptic Curves Cryptography over a Ring</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelhakim%20Chillali">Abdelhakim Chillali</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelhamid%20Tadmori"> Abdelhamid Tadmori</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammed%20Ziane"> Muhammed Ziane</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article we will study the elliptic curve defined over the ring An and we define the mathematical operations of ECC, which provides a high security and advantage for wireless applications compared to other asymmetric key cryptosystem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=elliptic%20curves" title="elliptic curves">elliptic curves</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20ring" title=" finite ring"> finite ring</a>, <a href="https://publications.waset.org/abstracts/search?q=cryptography" title=" cryptography"> cryptography</a>, <a href="https://publications.waset.org/abstracts/search?q=study" title=" study"> study</a> </p> <a href="https://publications.waset.org/abstracts/24042/improved-of-elliptic-curves-cryptography-over-a-ring" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24042.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">372</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> Ant System with Acoustic Communication</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saad%20Bougrine">Saad Bougrine</a>, <a href="https://publications.waset.org/abstracts/search?q=Salma%20Ouchraa"> Salma Ouchraa</a>, <a href="https://publications.waset.org/abstracts/search?q=Belaid%20Ahiod"> Belaid Ahiod</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelhakim%20Ameur%20El%20Imrani"> Abdelhakim Ameur El Imrani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ant colony optimization is an ant algorithm framework that took inspiration from foraging behaviour of ant colonies.

Similarly there is vast amount of research on the nonassociative structures of semigroups i.e. groupoids and that of rings i.e. nonassociative rings. However it is unfortunate that we do not have a parallel notions or study of non-associative near-rings. In this work we shall attempt to generalize a few known results and study the commutativity of Jordan ideal in 3-prime near-rings satisfying certain identities involving the Jordan ideal. We study the derivations satisfying certain differential identities on Jordan ideals of 3-prime near-rings. Moreover, we provide examples to show that hypothesis of our results are necessary. We give some new results and examples concerning the existence of Jordan ideal and derivations in near-rings.

In this regard, the ejector represents one of the promising solutions. The thermal ejector is a passive component used for thermal compression in refrigeration and cooling systems, usually activated by heat either waste or solar. The present study introduces a theoretical analysis of the cooling system which uses a gas ejector thermal compression. A theoretical model is developed and applied for the design and simulation of the ejector, as well as the whole cooling system. Besides the conservation equations of mass, energy and momentum, the gas dynamic equations, state equations, isentropic relations as well as some appropriate assumptions are applied to simulate the flow and mixing in the ejector. This model coupled with the equations of the other components (condenser, evaporator, pump, and generator) is used to analyze profiles of pressure and velocity (Mach number), as well as evaluation of the cycle cooling capacity. A FORTRAN program is developed to carry out the investigation. Properties of refrigerant R134a are calculated using real gas equations. Among many parameters, it is thought that the generator pressure is the cornerstone in the cycle, and hence considered as the key parameter in this investigation. Results show that the generator pressure has a great effect on the ejector and on the whole cooling system. At high generator pressures, strong shock waves inside the ejector are created, which lead to significant condenser pressure at the ejector exit. Additionally, at higher generator pressures, the designed system can deliver cooling capacity for high condensing pressure (hot season). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20cooling%20system" title="air cooling system">air cooling system</a>, <a href="https://publications.waset.org/abstracts/search?q=refrigeration" title=" refrigeration"> refrigeration</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20ejector" title=" thermal ejector"> thermal ejector</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20compression" title=" thermal compression"> thermal compression</a> </p> <a href="https://publications.waset.org/abstracts/104177/a-theoretical-analysis-of-air-cooling-system-using-thermal-ejector-under-variable-generator-pressure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104177.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">159</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> Performance Evaluation of Hierarchical Location-Based Services Coupled to the Greedy Perimeter Stateless Routing Protocol for Wireless Sensor Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rania%20Khadim">Rania Khadim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Erritali"> Mohammed Erritali</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelhakim%20Maaden"> Abdelhakim Maaden</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays Wireless Sensor Networks have attracted worldwide research and industrial interest, because they can be applied in various areas. Geographic routing protocols are very suitable to those networks because they use location information when they need to route packets. Obviously, location information is maintained by Location-Based Services provided by network nodes in a distributed way. In this paper we choose to evaluate the performance of two hierarchical rendezvous location based-services, GLS (Grid Location Service) and HLS (Hierarchical Location Service) coupled to the GPSR routing protocol (Greedy Perimeter Stateless Routing) for Wireless Sensor Network. The simulations were performed using NS2 simulator to evaluate the performance and power of the two services in term of location overhead, the request travel time (RTT) and the query Success ratio (QSR). This work presents also a new scalability performance study of both GLS and HLS, specifically, what happens if the number of nodes N increases. The study will focus on three qualitative metrics: The location maintenance cost, the location query cost and the storage cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=location%20based-services" title="location based-services">location based-services</a>, <a href="https://publications.waset.org/abstracts/search?q=routing%20protocols" title=" routing protocols"> routing protocols</a>, <a href="https://publications.waset.org/abstracts/search?q=scalability" title=" scalability"> scalability</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensor%20networks" title=" wireless sensor networks"> wireless sensor networks</a> </p> <a href="https://publications.waset.org/abstracts/48606/performance-evaluation-of-hierarchical-location-based-services-coupled-to-the-greedy-perimeter-stateless-routing-protocol-for-wireless-sensor-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48606.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">372</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> A Method to Compute Efficient 3D Helicopters Flight Trajectories Based On a Motion Polymorph-Primitives Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Konstanca%20Nikolajevic">Konstanca Nikolajevic</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Belanger"> Nicolas Belanger</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Duvivier"> David Duvivier</a>, <a href="https://publications.waset.org/abstracts/search?q=Rabie%20Ben%20Atitallah"> Rabie Ben Atitallah</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelhakim%20Artiba"> Abdelhakim Artiba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Finding the optimal 3D path of an aerial vehicle under flight mechanics constraints is a major challenge, especially when the algorithm has to produce real-time results in flight. Kinematics models and Pythagorian Hodograph curves have been widely used in mobile robotics to solve this problematic. The level of difficulty is mainly driven by the number of constraints to be saturated at the same time while minimizing the total length of the path. In this paper, we suggest a pragmatic algorithm capable of saturating at the same time most of dimensioning helicopter 3D trajectories’ constraints like: curvature, curvature derivative, torsion, torsion derivative, climb angle, climb angle derivative, positions. The trajectories generation algorithm is able to generate versatile complex 3D motion primitives feasible by a helicopter with parameterization of the curvature and the climb angle. An upper ”motion primitives’ concatenation” algorithm is presented based. In this article we introduce a new way of designing three-dimensional trajectories based on what we call the ”Dubins gliding symmetry conjecture”. This extremely performing algorithm will be soon integrated to a real-time decisional system dealing with inflight safety issues. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=robotics" title="robotics">robotics</a>, <a href="https://publications.waset.org/abstracts/search?q=aerial%20robots" title=" aerial robots"> aerial robots</a>, <a href="https://publications.waset.org/abstracts/search?q=motion%20primitives" title=" motion primitives"> motion primitives</a>, <a href="https://publications.waset.org/abstracts/search?q=helicopter" title=" helicopter"> helicopter</a> </p> <a href="https://publications.waset.org/abstracts/25294/a-method-to-compute-efficient-3d-helicopters-flight-trajectories-based-on-a-motion-polymorph-primitives-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25294.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">615</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> Prevalence of the Double Burden of Malnutrition in Women of Childbearing Age in Morocco: Coexistence of Iron Deficiency Anemia and Overweight</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fall%20Abdourahmane">Fall Abdourahmane</a>, <a href="https://publications.waset.org/abstracts/search?q=Lazrak%20Meryem"> Lazrak Meryem</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Hsaini%20Houda"> El Hsaini Houda</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Ammari%20Laila"> El Ammari Laila</a>, <a href="https://publications.waset.org/abstracts/search?q=Gamih%20Hasnae"> Gamih Hasnae</a>, <a href="https://publications.waset.org/abstracts/search?q=Yahyane%20Abdelhakim"> Yahyane Abdelhakim</a>, <a href="https://publications.waset.org/abstracts/search?q=Benjouad%20Abdelaziz"> Benjouad Abdelaziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Aguenaou%20Hassan"> Aguenaou Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Kari%20Khalid"> El Kari Khalid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The double burden of malnutrition (DBM), characterized by the coexistence of undernutrition and overnutrition, is a significant health challenge, particularly in low- and middle-income countries. In Morocco, 61.3% of women of reproductive age (WRA) are overweight or obese, including 30.4% who were obese, while 34.4% were anaemic, and 49.7% have iron deficiency anaemia. Objective: This study aims to determine the prevalence of DBM at the individual level among Moroccan WRA, defined by the coexistence of iron deficiency anaemia and overweight/obesity. Methods: a cross-sectional national survey was conducted among a representative sample of 2090 Moroccan WRA. Data collected included socio-economic parameters, anthropometric measurements, and blood samples. Haemoglobin levels were measured photometrically using Hemocue, while ferritin and CRP were assessed through immunoturbudimetry. Results: The prevalence of overweight/obesity, iron deficiency, anaemia and iron deficiency anaemia among WRA in Morocco were 60.2%, 30.6%, 34.4% and 50.0% respectively. The coexistence of overweight/obesity with anaemia and iron deficiency was observed in 19.2% and 16.3% of women, respectively. Among overweight/obese women, 32.5% were anaemic, 28.4% were iron deficient, and 47.6% had iron deficiency anaemia. the prevalence of DBM was higher in urban areas compared to rural settings. Conclusion: The coexistence of undernutrition and overnutrition among WRA highlights the urgent need for integrated public health interventions addressing both anaemia and obesity simultaneously. Tailored strategies should consider the specific socio-economic and geographical contexts to effectively combat this dual burden. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=the%20double%20burden%20of%20malnutrition" title="the double burden of malnutrition">the double burden of malnutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20deficiency%20anaemia" title=" iron deficiency anaemia"> iron deficiency anaemia</a>, <a href="https://publications.waset.org/abstracts/search?q=overweight" title=" overweight"> overweight</a>, <a href="https://publications.waset.org/abstracts/search?q=obesity" title=" obesity"> obesity</a> </p> <a href="https://publications.waset.org/abstracts/191962/prevalence-of-the-double-burden-of-malnutrition-in-women-of-childbearing-age-in-morocco-coexistence-of-iron-deficiency-anemia-and-overweight" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191962.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">33</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> Evaluation of the Skid Resistance of Asphalt Concrete Made of Local Low-Performance Aggregates Based on New Accelerated Polishing Machine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saci%20Abdelhakim%20Ferkous">Saci Abdelhakim Ferkous</a>, <a href="https://publications.waset.org/abstracts/search?q=Khedoudja%20Soudani"> Khedoudja Soudani</a>, <a href="https://publications.waset.org/abstracts/search?q=Smail%20Haddadi"> Smail Haddadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the results of a laboratory experimental study that explores the skid resistance of asphalt concrete mixtures made of local low-performance aggregates by partially replacing sand with olive mill waste (OMW). OMW was mixed with aggregates using a dry process by replacing sand with contents of 5%, 7%, 10% and 15%. The mechanical performances of the mixtures were evaluated using the Marshall and Duriez tests. A modified accelerated polishing machine was used as polishing equipment, and a British pendulum tester (BPT) was used to test the skid resistance of the samples. Finally, texture parameter analysis was performed using scanning electron microscopy (SEM) and Mountains Map software to assess the effect of OMW on the friction coefficient evolution. Using a distinct road wheel for a modified version of an accelerated polishing machine, which is normally used to determine the polished stone value of aggregates, the results showed that the addition of OMW up to 10% conferred a better skid resistance in comparison to normal asphalt concrete. The presence of olive mill waste in the mixture until 15% guarantees a gain of 22%-29% in skid resistance after polishing compared with the reference mix. Indeed, from texture parameter analysis, it was observed that there was differential wear of the lightweight aggregates (OMW) compared to the other aggregates during the polishing process, which created a new surface microtexture that had new peaks and led to a good level of friction compared to the mixtures without OMW. In general, it was found that OMW is a promising modifier for asphalt mixtures with both engineering and economic merits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=skid%20resistance" title="skid resistance">skid resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=olive%20mill%20waste" title=" olive mill waste"> olive mill waste</a>, <a href="https://publications.waset.org/abstracts/search?q=polishing%20resistance" title=" polishing resistance"> polishing resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=accelerated%20polishing%20machine" title=" accelerated polishing machine"> accelerated polishing machine</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20materials" title=" local materials"> local materials</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20development." title=" sustainable development."> sustainable development.</a> </p> <a href="https://publications.waset.org/abstracts/184593/evaluation-of-the-skid-resistance-of-asphalt-concrete-made-of-local-low-performance-aggregates-based-on-new-accelerated-polishing-machine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184593.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">56</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> Assessing the Double Burden of Malnutrition in Moroccan Women: A Focus on Iron Deficiency and Weight Disorders</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fall%20Abdourahmane">Fall Abdourahmane</a>, <a href="https://publications.waset.org/abstracts/search?q=Lazrak%20Meryem"> Lazrak Meryem</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Hsaini%20Houda"> El Hsaini Houda</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Ammari%20Laila"> El Ammari Laila</a>, <a href="https://publications.waset.org/abstracts/search?q=Gamih%20Hasnae"> Gamih Hasnae</a>, <a href="https://publications.waset.org/abstracts/search?q=Yahyane%20Abdelhakim"> Yahyane Abdelhakim</a>, <a href="https://publications.waset.org/abstracts/search?q=Benjouad%20Abdelaziz"> Benjouad Abdelaziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Aguenaou%20Hassan"> Aguenaou Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Kari%20Khalid"> El Kari Khalid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The double burden of malnutrition (DBM), defined by the concurrent occurrence of undernutrition and overnutrition, represents a critical public health issue, particularly in low- and middle-income countries. In Morocco, 61.3% of women of reproductive age (WRA) are classified as overweight or obese, with 30.4% meeting the criteria for obesity. Furthermore, 34.4% of WRA are affected by anaemia, and 49.7% present with iron deficiency anaemia. Objective: The objective of this study is to assess the individual-level prevalence of the double burden of malnutrition (DBM) among Moroccan WRA, focusing on the simultaneous presence of iron deficiency anaemia and overweight/obesity. Methods: A national cross-sectional survey was carried out on a representative sample of 2090 Moroccan WRA. The data collected encompassed blood samples, anthropometric measurements and socio-economic factors. Haemoglobin levels were assessed using a Hemocue device, while ferritin and CRP levels were determined through immunoturbidimetric analysis. Results: The prevalence of overweight/obesity among WRA in Morocco was 60.2%, iron deficiency affected 30.6%, anaemia was found in 34.4%, and 50.0% had iron deficiency anaemia. The coexistence of overweight/obesity with anaemia was observed in 19.2% and with iron deficiency in 16.3%. Among overweight/obese women, 32.5% were anaemic, 28.4% had iron deficiency, and 47.6% had iron deficiency anaemia. The prevalence of DBM was higher in urban areas compared to rural settings. Conclusion: The DBM among women of WRA showed an emergent reality of the interconnection and the coexistence at individual level of the undernutrition and the overnutrition. Therefore, effective and dual actions that could simultaneously address the double dimension of the DBM have to be implemented for the policy solutions to be successful. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=the%20double%20burden%20of%20malnutrition" title="the double burden of malnutrition">the double burden of malnutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20deficiency%20anemia" title=" iron deficiency anemia"> iron deficiency anemia</a>, <a href="https://publications.waset.org/abstracts/search?q=overweight" title=" overweight"> overweight</a>, <a href="https://publications.waset.org/abstracts/search?q=obesity" title=" obesity"> obesity</a> </p> <a href="https://publications.waset.org/abstracts/192091/assessing-the-double-burden-of-malnutrition-in-moroccan-women-a-focus-on-iron-deficiency-and-weight-disorders" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192091.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">20</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">© 2024 World Academy of Science, Engineering and Technology</div> </div> </footer> <a href="javascript:" id="return-to-top"><i class="fas fa-arrow-up"></i></a> <div class="modal" id="modal-template"> <div class="modal-dialog"> <div class="modal-content"> <div class="row m-0 mt-1"> <div class="col-md-12"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> </div> </div> <div class="modal-body"></div> </div> </div> </div> <script src="https://cdn.waset.org/static/plugins/jquery-3.3.1.min.js"></script> <script src="https://cdn.waset.org/static/plugins/bootstrap-4.2.1/js/bootstrap.bundle.min.js"></script> <script src="https://cdn.waset.org/static/js/site.js?v=150220211556"></script> <script> jQuery(document).ready(function() { /*jQuery.get("https://publications.waset.org/xhr/user-menu", function (response) { jQuery('#mainNavMenu').append(response);
