This happens due to the combined effect of the capillary force, buoyant weight of the particle and the viscous drag that the particle experiences in the liquid. The particle undergoes oscillations normal to the interface before it comes to rest on the interface. These oscillations, in turn, induce a flow on the interface which disperses the particles radially outward. This phenomenon has a significant role in the pollination of sea plants such as Ruppia in which the formation of ‘pollen rafts’ is the first step. This paper investigates, experimentally, the influence of the temperature of the liquid on which this dispersion occurs. It was observed that the frequency of oscillations of the particles decreased with the increase in the temperature of the liquid. It is because the magnitude of capillary force also decreased when the temperature of the liquid increased. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=particle%20dispersion" title="particle dispersion">particle dispersion</a>, <a href="https://publications.waset.org/abstracts/search?q=capillary%20force" title=" capillary force"> capillary force</a>, <a href="https://publications.waset.org/abstracts/search?q=viscous%20drag" title=" viscous drag"> viscous drag</a>, <a href="https://publications.waset.org/abstracts/search?q=oscillations" title=" oscillations"> oscillations</a> </p> <a href="https://publications.waset.org/abstracts/62666/the-experimental-investigation-of-temperature-influence-on-the-oscillations-of-particles-on-liquid-surfaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62666.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">19</span> Finite Element Modeling of Integral Abutment Bridge for Lateral Displacement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Naji">M.

This kind of bridges are becoming very popular due to different aspects such as good response under seismic loading, low initial costs, elimination of bearings and less maintenance. However, the main issue related to the analysis of this type of structures is dealing with soil-structure interaction of the abutment walls and the supporting piles. A two-dimensional, non-linear finite element (FE) model of an integral abutment bridge has been developed to study the effect of lateral time history displacement loading on the soil system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=integral%20abutment%20bridge" title="integral abutment bridge">integral abutment bridge</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20structure%20interaction" title=" soil structure interaction"> soil structure interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20modeling" title=" finite element modeling"> finite element modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=soil-pile%20interaction" title=" soil-pile interaction"> soil-pile interaction</a> </p> <a href="https://publications.waset.org/abstracts/2655/finite-element-modeling-of-integral-abutment-bridge-for-lateral-displacement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2655.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">289</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">18</span> The K-Distance Neighborhood Polynomial of a Graph</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soner%20Nandappa%20D.">Soner Nandappa D.</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Mohammed%20Naji"> Ahmed Mohammed Naji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In a graph G = (V, E), the distance from a vertex v to a vertex u is the length of shortest v to u path. The eccentricity e(v) of v is the distance to a farthest vertex from v. The diameter diam(G) is the maximum eccentricity. The k-distance neighborhood of v, for 0 ≤ k ≤ e(v), is Nk(v) = {u ϵ V (G) : d(v, u) = k}. In this paper, we introduce a new distance degree based topological polynomial of a graph G is called a k- distance neighborhood polynomial, denoted Nk(G, x). It is a polynomial with the coefficient of the term k, for 0 ≤ k ≤ e(v), is the sum of the cardinalities of Nk(v) for every v ϵ V (G).

The bias of MZM changes over time due to temperature, vibration, and aging factors. The change in the biasing causes distortion to the generated QAM signal which leads to deterioration of bit error rate (BER) performance. Therefore, it is critical to be able to lock MZM’s Q point to the required operating point for good performance. We propose a technique for automatic bias control (ABC) of QAM transmitter using BER measurements and gradient descent optimization algorithm. The proposed technique is attractive because it uses the pertinent metric, BER, which compensates for bias drifting independently from other system variations such as laser source output power. The proposed scheme performance and its operating principles are simulated using OptiSystem simulation software for 4-QAM and 16-QAM transmitters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automatic%20bias%20control" title="automatic bias control">automatic bias control</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20fiber%20communication" title=" optical fiber communication"> optical fiber communication</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20modulation" title=" optical modulation"> optical modulation</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20devices" title=" optical devices"> optical devices</a> </p> <a href="https://publications.waset.org/abstracts/137442/bit-error-rate-monitoring-for-automatic-bias-control-of-quadrature-amplitude-modulators" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137442.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">189</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">15</span> Study and Design of Solar Inverter System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaled%20A.%20Madi">Khaled A.

Due to rapid increase in industrial as well as domestic needs, solar energy becomes a good candidate for safe and easy to handle energy source, especially after it becomes available due to reduction of manufacturing price. The main part of the solar inverter system is the inverter where the DC is inverted to AC, where we try to minimize the loss of power to the minimum possible level by the use of microcontroller. In this work, a deep investigation is made experimentally as well as theoretically for a microcontroller based variable frequency power inverter. The microcontroller will provide the variable frequency Pulse Width Modulation (PWM) signal that will control the switching of the gate of the Insulating Gate Bipolar Transistor (IGBT) with less harmonics at the output of power inverter which can be fed to the public grid at high quality. The proposed work for single phase as well as three phases is also simulated using Matlab/Simulink where we found a good agreement between the simulated and the practical results, even though the experimental work were done in the laboratory of the academy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar" title="solar">solar</a>, <a href="https://publications.waset.org/abstracts/search?q=inverter" title=" inverter"> inverter</a>, <a href="https://publications.waset.org/abstracts/search?q=PV" title=" PV"> PV</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20inverter%20system" title=" solar inverter system"> solar inverter system</a> </p> <a href="https://publications.waset.org/abstracts/9073/study-and-design-of-solar-inverter-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9073.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">462</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">14</span> Unspoken Delights: Creative Strategies for Bypass Censorship System and Depicting Male-Female Relationships in Iranian Cinema</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parsa%20Naji">Parsa Naji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Following the Iran Islamic Revolution in 1979 and the subsequent formation of a theocratic regime, the new regime implemented stringent regulations and a complicated censorship system in the film industry. Thereupon, the screening of films showing the relationships between males and females encountered numerous limitations. Not only did these limits encompass the physical portrayal of the relationship between males and females, but also the dialogues containing explicit sexual or even passionate romantic themes, resulting in a film being permanently consigned to archival storage. However, despite these limitations, Iranian filmmakers persevered in creating their interesting cinematic works. Throughout the years after the revolution, Iranian directors have navigated a series of challenges and obstacles, employing innovative and unconventional methods to bypass the rigorous censorship system imposed by the government, ensuring the screening of their films. This study aims to analyze the creative approaches employed by Iranian filmmakers to circumvent governmental censorship regulations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=censorship" title="censorship">censorship</a>, <a href="https://publications.waset.org/abstracts/search?q=Iranian%20cinema" title=" Iranian cinema"> Iranian cinema</a>, <a href="https://publications.waset.org/abstracts/search?q=Islamic%20revolution" title=" Islamic revolution"> Islamic revolution</a>, <a href="https://publications.waset.org/abstracts/search?q=male-female%20relationship" title=" male-female relationship"> male-female relationship</a> </p> <a href="https://publications.waset.org/abstracts/186926/unspoken-delights-creative-strategies-for-bypass-censorship-system-and-depicting-male-female-relationships-in-iranian-cinema" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186926.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">47</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">13</span> Problems of Translating Technical Terms from English into Arabic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisreen%20Naji%20Al-Khawaldeh">Nisreen Naji Al-Khawaldeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Lara%20Ahmad%20Mansour%20El-Awar"> Lara Ahmad Mansour El-Awar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study investigated the strategies MA translation students used for translating technical terms, the most common obstacles they encountered in translating such terms, and the motives behind using such terms as they are in their original form despite their translatability into Arabic. To achieve these objectives, a translation test was administered to 100 MA students specialising in translation at both Hashemite University and The University of Jordan. It consisted of two parts: (a) 50 English technical terms to be translated (b) two questions to be answered concerning the challenges or problems encountered while translating the previous technical terms and the motives that drive them to use most of the English technical terms as they are despite their translatability into Arabic. The analysis of the results revealed that MA translation students faced problems in translating technical terms, namely the inability to find the equivalent form for the given technical terms, the use of literal translation, and the wider use of loan-words type. Besides, the students used different strategies to translate the technical terms, namely borrowing (i.e., loan- words), paraphrasing, synonymy, naturalization, equivalence, and literal translation. Moreover, it was also revealed that most technical terms were used as they are in the source language despite their translatability into Arabic because these technical terms are easier to use in English rather than in Arabic. Also, when these terms were introduced to the Arab world, they were introduced in English, not in Arabic. So, the brain links these objects to their English terms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arabic" title="arabic">arabic</a>, <a href="https://publications.waset.org/abstracts/search?q=english" title=" english"> english</a>, <a href="https://publications.waset.org/abstracts/search?q=technical%20terms" title=" technical terms"> technical terms</a>, <a href="https://publications.waset.org/abstracts/search?q=translation%20strategies" title=" translation strategies"> translation strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=translation%20problems" title=" translation problems"> translation problems</a> </p> <a href="https://publications.waset.org/abstracts/140020/problems-of-translating-technical-terms-from-english-into-arabic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140020.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">281</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> Synthesis and Characterization of Partially Oxidized Graphite Oxide for Solar Energy Storage Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghada%20Ben%20Hamad">Ghada Ben Hamad</a>, <a href="https://publications.waset.org/abstracts/search?q=Zohir%20Younsi"> Zohir Younsi</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabien%20Salaun"> Fabien Salaun</a>, <a href="https://publications.waset.org/abstracts/search?q=Hassane%20Naji"> Hassane Naji</a>, <a href="https://publications.waset.org/abstracts/search?q=Noureddine%20Lebaz"> Noureddine Lebaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The graphene oxide (GO) material has attracted much attention for solar energy applications. This paper reports the synthesis and characterization of partially oxidized graphite oxide (GTO). GTO was obtained by modified Hummers method, which is based on the chemical oxidation of natural graphite. Several samples were prepared with different oxidation degree by an adjustment of the oxidizing agent’s amount. The effect of the oxidation degree on the chemical structure and on the morphology of GTO was determined by using Fourier transform infrared (FT-IR) spectroscopy, Energy Dispersive X-ray Spectroscopy (EDS), and scanning electronic microscope (SEM). The thermal stability of GTO was evaluated by using thermogravimetric analyzer (TGA) in Nitrogen atmosphere. The results indicate high degree oxidation of graphite oxide for each sample, proving that the process is efficient. The GTO synthesized by modified Hummers method shows promising characteristics. Graphene oxide (GO) obtained by exfoliation of GTO are recognized as a good candidate for thermal energy storage, and it will be used as solid shell material in the encapsulation of phase change materials (PCM). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=modified%20hummers%20method" title="modified hummers method">modified hummers method</a>, <a href="https://publications.waset.org/abstracts/search?q=graphite%20oxide" title=" graphite oxide"> graphite oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidation%20degree" title=" oxidation degree"> oxidation degree</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy%20storage" title=" solar energy storage"> solar energy storage</a> </p> <a href="https://publications.waset.org/abstracts/117537/synthesis-and-characterization-of-partially-oxidized-graphite-oxide-for-solar-energy-storage-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117537.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">118</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> Broad Spectrum Biofilm Inhibition by Chitosanase Purified from Bacillus licheniformis Isolated from Spoilt Vegetables</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sahira%20Nsayef%20Muslim">Sahira Nsayef Muslim</a>, <a href="https://publications.waset.org/abstracts/search?q=Israa%20M.%20S.%20Al-Kadmy"> Israa M.

Chitosanase was purified to homogeneity with a recovery yield of 35.71% and 5.5 fold of purification by using ammonium sulfate at 45% saturation followed by ion exchange chromatography on DEAE-cellulose column and gel filtration chromatography on Sephadex G-100 column. The purified chitosanase inhibited the biofilm formation ability for all Gram-negative and Gram-positive biofilm-forming bacteria (biofilm producers) after using Congo Red agar and Microtiter plates methods. Highly antibiofilm of chitosanase recorded against Pseudomonas aeruginosa followed by Klebsiella pneumoniae with reduction of biofilm formation ratio to 22 and 29%, respectively compared with (100)% of control. Thus, chitosanase has promising benefit as antibiofilm agent against biofilm forming pathogenic bacteria and has promising application as alternative antibiofilm agents to combat the growing number of multidrug-resistant pathogen-associated infections, especially in situation where biofilms are involved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chitosanase" title="chitosanase">chitosanase</a>, <a href="https://publications.waset.org/abstracts/search?q=Bacillus%20licheniformis" title=" Bacillus licheniformis"> Bacillus licheniformis</a>, <a href="https://publications.waset.org/abstracts/search?q=vegetables" title=" vegetables"> vegetables</a>, <a href="https://publications.waset.org/abstracts/search?q=biofilm" title=" biofilm"> biofilm</a> </p> <a href="https://publications.waset.org/abstracts/56330/broad-spectrum-biofilm-inhibition-by-chitosanase-purified-from-bacillus-licheniformis-isolated-from-spoilt-vegetables" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56330.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">384</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">10</span> Digital Sustainable Human Resource Management Model Innovation Based on Dynamic Capabilities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Kargar%20Shouraki">Mohammad Kargar Shouraki</a>, <a href="https://publications.waset.org/abstracts/search?q=Naji%20Yazdi"> Naji Yazdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Emami"> Mohsen Emami</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The environmental and social challenges have caused the organizations to put further attention and emphasis on sustainable growth and developing strategies for sustainability. Since human is both the target of development and the agent of development at the same time, one of the most important factors in the development of the sustainability strategy in organizations is the human factor. In addition, organizations have been facing the new challenge of digital transformation which impacts the human factor, meanwhile, undeniably, the human factor contributes to such transformation. Therefore, organizations are facing the challenge of digital human resource management (HRM). Thus, the present study aims to investigate how an HRM model should be so that it not only can help the consideration and of the business sustainability requirements but also can make the highest and the most appropriate positive, not destructive, utilization of the digital transformations. Furthermore, the success of the HRM regarding the two sustainability and digital transformation challenges requires dynamic human competencies, which are addressed as digital/sustainable human dynamic capabilities in this paper. The present study is conducted using a hybrid methodology consisting of the qualitative methods of meta-synthesis and content analysis and the quantitative method of interpretive-structural model (ISM). Finally, a rotatory model, including 3 approaches, 3 perspectives, and 9 dimensions, is presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainable%20human%20resource%20management" title="sustainable human resource management">sustainable human resource management</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20human%20resource%20management" title=" digital human resource management"> digital human resource management</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%2Fsustainable%20human%20dynamic%20capabilities" title=" digital/sustainable human dynamic capabilities"> digital/sustainable human dynamic capabilities</a>, <a href="https://publications.waset.org/abstracts/search?q=talent%20management" title=" talent management"> talent management</a> </p> <a href="https://publications.waset.org/abstracts/154237/digital-sustainable-human-resource-management-model-innovation-based-on-dynamic-capabilities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154237.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">118</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">9</span> Formation of Protective Aluminum-Oxide Layer on the Surface of Fe-Cr-Al Sintered-Metal-Fibers via Multi-Stage Thermal Oxidation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Loai%20Ben%20Naji">Loai Ben Naji</a>, <a href="https://publications.waset.org/abstracts/search?q=Osama%20M.%20Ibrahim"> Osama M.

The oxide-scale layer was developed via multi-stage thermal oxidation at 930 <sup>o</sup>C for 1 hour, followed by 1 hour at 960 <sup>o</sup>C, and finally at 990 <sup>o</sup>C for 2 hours. Scanning Electron Microscope (SEM) images show that the multi-stage thermal oxidation resulted in the formation of predominantly Al<sub>2</sub>O<sub>3</sub> platelets-like and whiskers. SEM images also reveal non-uniform oxide-scale growth on the surface of the fibers. Furthermore, peeling/spalling of the alumina protective layer occurred after minimum handling, which indicates weak adhesion forces between the protective layer and the base metal alloy.  Energy Dispersive Spectroscopy (EDS) analysis of the heat-treated Fe-Cr-Al sintered-metal-fibers confirmed the high aluminum content on the surface of the protective layer, and the low aluminum content on the exposed base metal alloy surface. In conclusion, the failure of the oxide-scale protective layer exposes the base metal alloy to further oxidation, and the fragile non-uniform oxide-scale is not suitable as a support for catalysts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high-temperature%20oxidation" title="high-temperature oxidation">high-temperature oxidation</a>, <a href="https://publications.waset.org/abstracts/search?q=iron-chromium-aluminum%20alloy" title=" iron-chromium-aluminum alloy"> iron-chromium-aluminum alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=alumina%20protective%20layer" title=" alumina protective layer"> alumina protective layer</a>, <a href="https://publications.waset.org/abstracts/search?q=sintered-metal-fibers" title=" sintered-metal-fibers"> sintered-metal-fibers</a> </p> <a href="https://publications.waset.org/abstracts/97290/formation-of-protective-aluminum-oxide-layer-on-the-surface-of-fe-cr-al-sintered-metal-fibers-via-multi-stage-thermal-oxidation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97290.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">205</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> The Impact of Gender Differences on the Expressions of Refusal in Jordanian Arabic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hanan%20Yousef">Hanan Yousef</a>, <a href="https://publications.waset.org/abstracts/search?q=Nisreen%20Naji%20Al-Khawaldeh"> Nisreen Naji Al-Khawaldeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study investigates the use of the expression of refusal by native speakers of Jordanian Arabic (NSsJA) in different social situations (i.e. invitations, suggestions, and offers). It also investigates the influence of gender on the refusal realization patterns within the Jordanian culture to provide a better insight into the relation between situations, strategies and gender in the Jordanian culture. To that end, a group of 70 participants, including 35 male and 35 female students from different departments at the Hashemite University (HU) participated in this study using mixed methods (i.e. Discourse Completion Test (DCT), interviews and naturally occurring data). Data were analyzed in light of a developed coding scheme. The results showed that NSsJA preferred indirect strategies which mitigate the interaction such as "excuse, reason and, explanation" strategy more than other strategies which aggravate the interaction such as "face-threatening" strategy. Moreover, the analysis of this study has revealed a considerable impact of gender on the use of linguistic forms expressing refusal among NSsJA. Significant differences in the results of the Chi-square test relating the effect of participants' gender indicate that both males and females were conscious of the gender of their interlocutors. The findings provide worthwhile insights into the relation amongst types of communicative acts and the rapport between people in social interaction. They assert that refusal should not be labeled as face threatening act since it does not always pose a threat in some cases especially where refusal is expressed among friends, relatives and family members. They highlight some distinctive culture-specific features of the communicative acts of refusal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender" title="gender">gender</a>, <a href="https://publications.waset.org/abstracts/search?q=Jordanian%20Arabic" title=" Jordanian Arabic"> Jordanian Arabic</a>, <a href="https://publications.waset.org/abstracts/search?q=politeness" title=" politeness"> politeness</a>, <a href="https://publications.waset.org/abstracts/search?q=refusals" title=" refusals"> refusals</a>, <a href="https://publications.waset.org/abstracts/search?q=speech%20act" title=" speech act"> speech act</a> </p> <a href="https://publications.waset.org/abstracts/120556/the-impact-of-gender-differences-on-the-expressions-of-refusal-in-jordanian-arabic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120556.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">166</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">7</span> The Effect of Diapirs on the Geometry and Evolution of the Ait Ourir Basin, High Atlas Mountains of Marrakesh, Morocco</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hadach%20Fatiha">Hadach Fatiha</a>, <a href="https://publications.waset.org/abstracts/search?q=Algouti%20Ahmed"> Algouti Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Algouti%20Abdellah"> Algouti Abdellah</a>, <a href="https://publications.waset.org/abstracts/search?q=Jdaba%20Naji"> Jdaba Naji</a>, <a href="https://publications.waset.org/abstracts/search?q=Es-Sarrar%20Othman"> Es-Sarrar Othman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mourabit%20Zahra"> Mourabit Zahra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates the structure and evolution of diapirism in the Ait Ourir basin, located in the High Atlas of Marrakesh, using structural and sedimentological fieldwork integrated with field mapping. A tectonic-sedimentological study of the Mesozoic cover of the Ait Ourir basin area revealed that these units were subjected to important saccadic halokinetic activity, reflected by anticline structures associated with regional faults that created several synclinal mini-basins. However, the lack of seismic coverage in the study area makes the proposed interpretation based on extrapolations of information observed on the surface. In this work, we suggest that faults and salt activity led to the formation of different structures within the studied area. The growth of the Triassic evaporites at different stages during the Mesozoic is reflected by progressive and local unconformities, recorded as having different ages. These structures created high diapiric zones with reduced sedimentation, showing abrupt lateral thickness variations in several places where this activity was occurring; this is clearly defined within the Wanina and Jbel Sour’s mini-basins, where the Senonian was observed to rest at an angular unconformity over the entire sedimentary cover encompassing the time period from the Liassic to the Turonian. The diapirism associated with the major faults, especially encountered between the basins, is often accompanied by late Triassic volcanic material. This diapir-fault relationship resulted in shallow and often depocentric zones in a pull-apart system within a distensive context. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diapir" title="diapir">diapir</a>, <a href="https://publications.waset.org/abstracts/search?q=evaporites" title=" evaporites"> evaporites</a>, <a href="https://publications.waset.org/abstracts/search?q=faults" title=" faults"> faults</a>, <a href="https://publications.waset.org/abstracts/search?q=pull-apart" title=" pull-apart"> pull-apart</a>, <a href="https://publications.waset.org/abstracts/search?q=Mesozoic%20cover" title=" Mesozoic cover"> Mesozoic cover</a>, <a href="https://publications.waset.org/abstracts/search?q=Ait%20Ourir" title=" Ait Ourir"> Ait Ourir</a>, <a href="https://publications.waset.org/abstracts/search?q=western%20High%20Atlas" title=" western High Atlas"> western High Atlas</a>, <a href="https://publications.waset.org/abstracts/search?q=Morocco" title=" Morocco"> Morocco</a> </p> <a href="https://publications.waset.org/abstracts/174795/the-effect-of-diapirs-on-the-geometry-and-evolution-of-the-ait-ourir-basin-high-atlas-mountains-of-marrakesh-morocco" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174795.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">71</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> A Rational Strategy to Maximize the Value-Added Products by Selectively Converting Components of Inferior Heavy Oil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kashan%20Bashir">Kashan Bashir</a>, <a href="https://publications.waset.org/abstracts/search?q=Salah%20Naji%20Ahmed%20Sufyan"> Salah Naji Ahmed Sufyan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mirza%20Umar%20Baig"> Mirza Umar Baig</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, n-dodecane, tetralin, decalin, and tetramethybenzene (TMBE) were used as model compounds of alkanes, naphthenic-aromatic, cycloalkanes and alkyl-benzenes presented in hydro-diesel. The catalytic cracking properties of four model compounds over Y zeolite catalyst (Y-Cat.) and ZSM-5 zeolite catalysts (ZSM-5-Cat.) were probed. The experiment results revealed that high conversion of macromolecular paraffin and naphthenic aromatics were achieved over Y-Cat, whereas its low cracking activity of intermediate products micromolecules paraffin and olefin and high activity of hydride transfer reaction goes against the production of value-added products (light olefin and gasoline). In contrast, despite the fact that the hydride transfer reaction was greatly inhabited over ZSM-5-Cat, the low conversion of macromolecules was observed attributed to diffusion limitations. Interestingly, the mixed catalyst compensates for the shortcomings of the two catalysts, and a “relay reaction” between Y-Cat and ZSM-5-Cat was proposed. Specifically, the added Y-Cat acts as a “pre-cracking booster site” and promotes macromolecules conversion. The addition of ZSM-5-Cat not only significantly suppresses the hydride transfer reaction but also contributes to the cracking of immediate products paraffin and olefin into ethylene and propylene, resulting in a high yield of alkyl-benzene (gasoline), ethylene, and propylene with a low yield of naphthalene (LCO) and coke. The catalytic cracking evaluation experiments of mixed hydro-LCO were also performed to further clarify the “relay reaction” above, showing the highest yield of LPG and gasoline over mixed catalyst. The results indicate that the Y-cat and ZSM-5-cat have a synergistic effect on the conversion of hydro-diesel and corresponding value-added product yield and selective coke yield. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=synergistic%20effect" title="synergistic effect">synergistic effect</a>, <a href="https://publications.waset.org/abstracts/search?q=hydro-diesel%20cracking" title=" hydro-diesel cracking"> hydro-diesel cracking</a>, <a href="https://publications.waset.org/abstracts/search?q=FCC" title=" FCC"> FCC</a>, <a href="https://publications.waset.org/abstracts/search?q=zeolite%20catalyst" title=" zeolite catalyst"> zeolite catalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=ethylene%20and%20propylene" title=" ethylene and propylene"> ethylene and propylene</a> </p> <a href="https://publications.waset.org/abstracts/173070/a-rational-strategy-to-maximize-the-value-added-products-by-selectively-converting-components-of-inferior-heavy-oil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173070.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">72</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> Remote Vital Signs Monitoring in Neonatal Intensive Care Unit Using a Digital Camera</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatema-Tuz-Zohra%20Khanam">Fatema-Tuz-Zohra Khanam</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Al-Naji"> Ali Al-Naji</a>, <a href="https://publications.waset.org/abstracts/search?q=Asanka%20G.%20Perera"> Asanka G.

Therefore, remote monitoring of the vital sign is desired in both clinical and non-clinical settings to overcome these issues. Camera-based vital signs monitoring is a recent technology for these applications with many positive attributes. However, there are still limited camera-based studies on neonates in a clinical setting. In this study, the heart rate (HR) and respiratory rate (RR) of eight infants at the Neonatal Intensive Care Unit (NICU) in Flinders Medical Centre were remotely monitored using a digital camera applying color and motion-based computational methods. The region-of-interest (ROI) was efficiently selected by incorporating an image decomposition method. Furthermore, spatial averaging, spectral analysis, band-pass filtering, and peak detection were also used to extract both HR and RR. The experimental results were validated with the ground truth data obtained from an ECG monitor and showed a strong correlation using the Pearson correlation coefficient (PCC) 0.9794 and 0.9412 for HR and RR, respectively. The RMSE between camera-based data and ECG data for HR and RR were 2.84 beats/min and 2.91 breaths/min, respectively. A Bland Altman analysis of the data also showed a close correlation between both data sets with a mean bias of 0.60 beats/min and 1 breath/min, and the lower and upper limit of agreement -4.9 to + 6.1 beats/min and -4.4 to +6.4 breaths/min for both HR and RR, respectively. Therefore, video camera imaging may replace conventional contact-based monitoring in NICU and has potential applications in other contexts such as home health monitoring. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neonates" title="neonates">neonates</a>, <a href="https://publications.waset.org/abstracts/search?q=NICU" title=" NICU"> NICU</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20camera" title=" digital camera"> digital camera</a>, <a href="https://publications.waset.org/abstracts/search?q=heart%20rate" title=" heart rate"> heart rate</a>, <a href="https://publications.waset.org/abstracts/search?q=respiratory%20rate" title=" respiratory rate"> respiratory rate</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20decomposition" title=" image decomposition"> image decomposition</a> </p> <a href="https://publications.waset.org/abstracts/147786/remote-vital-signs-monitoring-in-neonatal-intensive-care-unit-using-a-digital-camera" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147786.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">104</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> Synthesis and Characterization of Capric-Stearic Acid/ Graphene Oxide-TiO₂ Microcapsules for Solar Energy Storage and Photocatalytic Efficiency</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghada%20Ben%20Hamad">Ghada Ben Hamad</a>, <a href="https://publications.waset.org/abstracts/search?q=Zohir%20Younsi"> Zohir Younsi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hassane%20Naji"> Hassane Naji</a>, <a href="https://publications.waset.org/abstracts/search?q=Noureddine%20Lebaz"> Noureddine Lebaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Naoual%20Belouaggadia"> Naoual Belouaggadia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study deals with a bifunctional micro-encapsulated phase change (MCP) material, capric-stearic acid/graphene oxide-TiO2, which has been successfully developed by in situ hydrolysis and polycondensation of tetrabutyl titanate and modification of graphene oxide (GO) on the TiO2 doped shell. The use of graphene and doped TiO2 is a promising approach to provide photocatalytic activity under visible light and improve the microcapsules physicochemical properties. The morphology and chemical structure of the resulting microcapsule samples were determined by using Fourier transform infrared (FT-IR) spectroscopy, scanning electronic microscope (SEM), and X-ray diffractometer (XRD) methods. The ultraviolet, visible spectrophotometer (UV–vis), the differential scanning calorimeter (DSC) and the thermogravimetric analyzer (TGA) were used to investigate the absorption of visible and ultraviolet (UV), the thermal properties, and thermal stabilities of the microcapsules. Note that, the visible light photocatalytic activity was assessed for the toluene and benzene gaseous removal in a suitable test room. The microcapsules exhibit an interesting spherical morphology and an average diameter of 15 to 25 μm. The addition of graphene can enhance the rigidity of the shell and improve the microcapsules thermal reliability. At the same time, the thermal analysis tests showed that the synthesized microcapsules had a high solar thermal energy-storage and better thermal stability. In addition, the capric-stearic acid microcapsules exhibited high solar photocatalytic activity with respect to atmospheric pollutants under natural sunlight. The fatty acid samples obtained with the GO/TiO2 shell showed great potential for applications of solar energy storage, solar photocatalytic degradation of air pollutants and buildings energy conservation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermal%20energy%20storage" title="thermal energy storage">thermal energy storage</a>, <a href="https://publications.waset.org/abstracts/search?q=microencapsulation" title=" microencapsulation"> microencapsulation</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20dioxide" title=" titanium dioxide"> titanium dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=photocatalysis" title=" photocatalysis"> photocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene%20oxide" title=" graphene oxide"> graphene oxide</a> </p> <a href="https://publications.waset.org/abstracts/103464/synthesis-and-characterization-of-capric-stearic-acid-graphene-oxide-tio2-microcapsules-for-solar-energy-storage-and-photocatalytic-efficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103464.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">131</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> Non-Conformance Clearance through an Intensified Mentorship towards ISO 15189 Accreditation: The Case of Jimma and Hawassa Hospital Microbiology Laboratories, Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dawit%20Assefa">Dawit Assefa</a>, <a href="https://publications.waset.org/abstracts/search?q=Kassaye%20Tekie"> Kassaye Tekie</a>, <a href="https://publications.waset.org/abstracts/search?q=Gebrie%20Alebachew"> Gebrie Alebachew</a>, <a href="https://publications.waset.org/abstracts/search?q=Degefu%20Beyene"> Degefu Beyene</a>, <a href="https://publications.waset.org/abstracts/search?q=Bikila%20Alemu"> Bikila Alemu</a>, <a href="https://publications.waset.org/abstracts/search?q=Naji%20Mohammed"> Naji Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Asnakech%20Agegnehu"> Asnakech Agegnehu</a>, <a href="https://publications.waset.org/abstracts/search?q=Seble%20Tsehay"> Seble Tsehay</a>, <a href="https://publications.waset.org/abstracts/search?q=Geremew%20Tasew"> Geremew Tasew</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Implementation of a Laboratory Quality Management System (LQMS) is critical to ensure accurate, reliable, and efficient laboratory testing of antimicrobial resistance (AMR). However, limited LQMS implementation and progress toward accreditation in the AMR surveillance laboratory testing setting exist in Ethiopia. By addressing non-conformances (NCs) and working towards accreditation, microbiology laboratories can improve the quality of their services, increase staff competence, and contribute to mitigate the spread of AMR. Methods: Using standard ISO 15189 horizontal and vertical assessment checklists, certified assessors identified NCs at Hawassa and Jimma Hospital microbiology laboratories. The Ethiopian Public Health Institute AMR mentors and IDDS staff prioritized closing the NCs through the implementation of an intensified mentorship program that included ISO 15189 orientation training, resource allocation, and action plan development. Results: For the two facilities to clear their NCs, an intensified mentorship approach was adopted by providing ISO 15189 orientation training, provision of buffer reagents, controls, standards, and axillary equipment, and facilitating equipment maintenance and calibration. Method verification and competency assessment were also conducted along with the implementation of standard operating procedures and recommended corrective actions. This approach enhanced the laboratory's readiness for accreditation. After addressing their NCs, the two laboratories applied to Ethiopian Accreditation Services for ISO 15189 accreditation. Conclusions: Clearing NCs through the implementation of intensified mentorship was crucial in preparing the two laboratories for accreditation and improving quality laboratory test results. This approach can guide other microbiology laboratories’ accreditation attainment efforts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=non-conformance%20clearance" title="non-conformance clearance">non-conformance clearance</a>, <a href="https://publications.waset.org/abstracts/search?q=intensified%20mentorship" title=" intensified mentorship"> intensified mentorship</a>, <a href="https://publications.waset.org/abstracts/search?q=accreditation" title=" accreditation"> accreditation</a>, <a href="https://publications.waset.org/abstracts/search?q=ISO%2015189" title=" ISO 15189"> ISO 15189</a> </p> <a href="https://publications.waset.org/abstracts/179374/non-conformance-clearance-through-an-intensified-mentorship-towards-iso-15189-accreditation-the-case-of-jimma-and-hawassa-hospital-microbiology-laboratories-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179374.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">92</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> Neighborhood Sustainability Assessment Tools: A Conceptual Framework for Their Use in Building Adaptive Capacity to Climate Change</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sally%20Naji">Sally Naji</a>, <a href="https://publications.waset.org/abstracts/search?q=Julie%20Gwilliam"> Julie Gwilliam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Climate change remains a challenging matter for the human and the built environment in the 21st century, where the need to consider adaptation to climate change in the development process is paramount. However, there remains a lack of information regarding how we should prepare responses to this issue, such as through developing organized and sophisticated tools enabling the adaptation process. This study aims to build a systematic framework approach to investigate the potentials that Neighborhood Sustainability Assessment tools (NSA) might offer in enabling both the analysis of the emerging adaptive capacity to climate change. The analysis of the framework presented in this paper aims to discuss this issue in three main phases. The first part attempts to link sustainability and climate change, in the context of adaptive capacity. It is argued that in deciding to promote sustainability in the context of climate change, both the resilience and vulnerability processes become central. However, there is still a gap in the current literature regarding how the sustainable development process can respond to climate change. As well as how the resilience of practical strategies might be evaluated. It is suggested that the integration of the sustainability assessment processes with both the resilience thinking process, and vulnerability might provide important components for addressing the adaptive capacity to climate change. A critical review of existing literature is presented illustrating the current lack of work in this field, integrating these three concepts in the context of addressing the adaptive capacity to climate change. The second part aims to identify the most appropriate scale at which to address the built environment for the climate change adaptation. It is suggested that the neighborhood scale can be considered as more suitable than either the building or urban scales. It then presents the example of NSAs, and discusses the need to explore their potential role in promoting the adaptive capacity to climate change. The third part of the framework presents a comparison among three example NSAs, BREEAM Communities, LEED-ND, and CASBEE-UD. These three tools have been selected as the most developed and comprehensive assessment tools that are currently available for the neighborhood scale. This study concludes that NSAs are likely to present the basis for an organized framework to address the practical process for analyzing and yet promoting Adaptive Capacity to Climate Change. It is further argued that vulnerability (exposure & sensitivity) and resilience (Interdependence & Recovery) form essential aspects to be addressed in the future assessment of NSA’s capability to adapt to both short and long term climate change impacts. Finally, it is acknowledged that further work is now required to understand impact assessment in terms of the range of physical sectors (Water, Energy, Transportation, Building, Land Use and Ecosystems), Actor and stakeholder engagement as well as a detailed evaluation of the NSA indicators, together with a barriers diagnosis process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptive%20capacity" title="adaptive capacity">adaptive capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=NSA%20tools" title=" NSA tools"> NSA tools</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience" title=" resilience"> resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/38507/neighborhood-sustainability-assessment-tools-a-conceptual-framework-for-their-use-in-building-adaptive-capacity-to-climate-change" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38507.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">381</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> Impact of Maternal Nationality on Caesarean Section Rate Variation in a High-income Country</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saheed%20Shittu">Saheed Shittu</a>, <a href="https://publications.waset.org/abstracts/search?q=Lolwa%20Alansari"> Lolwa Alansari</a>, <a href="https://publications.waset.org/abstracts/search?q=Fahed%20Nattouf"> Fahed Nattouf</a>, <a href="https://publications.waset.org/abstracts/search?q=Tawa%20Olukade"> Tawa Olukade</a>, <a href="https://publications.waset.org/abstracts/search?q=Naji%20Abdallah"> Naji Abdallah</a>, <a href="https://publications.waset.org/abstracts/search?q=Tamara%20Alshdafat"> Tamara Alshdafat</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarra%20Amdouni"> Sarra Amdouni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cesarean sections (CS), a highly regarded surgical intervention for improving fetal-maternal outcomes and serving as an integral part of emergency obstetric services, are not without complications. Although CS has many advantages, it poses significant risks to both mother and child and increases healthcare expenditures in the long run. The escalating global prevalence of CS, coupled with variations in rates among immigrant populations, has prompted an inquiry into the correlation between CS rates and the nationalities of women undergoing deliveries at Al-Wakra Hospital (AWH), Qatar's second-largest public maternity hospital. This inquiry is motivated by the notable CS rate of 36%, deemed high in comparison to the 34% recorded across other Hamad Medical Corporation (HMC) maternity divisions This is Qatar's first comprehensive investigation of Caesarean section rates and nationalities. A retrospective cross-sectional study was conducted, and data for all births delivered in 2019 were retrieved from the hospital's electronic medical records. The CS rate, the crude rate, and adjusted risks of Caesarean delivery for mothers from each nationality were determined. The common indications for CS were analysed based on nationality. The association between nationality and Caesarean rates was examined using binomial logistic regression analysis considering Qatari women as a standard reference group. The correlation between the CS rate in the country of nationality and the observed CS rate in Qatar was also examined using Pearson's correlation. This study included 4,816 births from 69 different nationalities. CS was performed in 1767 women, equating to 36.5%. The nationalities with the highest CS rates were Egyptian (49.6%), Lebanese (45.5%), Filipino and Indian (both 42.2%). Qatari women recorded a CS rate of 33.4%. The major indication for elective CS was previous multiple CS (39.9%) and one prior CS, where the patient declined vaginal birth after the cesarean (VBAC) option (26.8%). A distinct pattern was noticed: elective CS was predominantly performed on Arab women, whereas emergency CS was common among women of Asian and Sub-Saharan African nationalities. Moreover, a significant correlation was found between the CS rates in Qatar and the women's countries of origin. Also, a high CS rate was linked to instances of previous CS. As a result of these insights, strategic interventions were successfully implemented at the facility to mitigate unwarranted CS, resulting in a notable reduction in CS rate from 36.5% in 2019 to 34% in 2022. This proves the efficacy of the meticulously researched approach. The focus has now shifted to reducing primary CS rates and facilitating well-informed decisions regarding childbirth methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maternal%20nationality" title="maternal nationality">maternal nationality</a>, <a href="https://publications.waset.org/abstracts/search?q=caesarean%20section%20rate%20variation" title=" caesarean section rate variation"> caesarean section rate variation</a>, <a href="https://publications.waset.org/abstracts/search?q=migrants" title=" migrants"> migrants</a>, <a href="https://publications.waset.org/abstracts/search?q=high-income%20country" title=" high-income country"> high-income country</a> </p> <a href="https://publications.waset.org/abstracts/179021/impact-of-maternal-nationality-on-caesarean-section-rate-variation-in-a-high-income-country" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179021.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">70</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);
