The dependency of the true stress and specially the variation of volume strain have been investigated, the volume strain due to the phenomena of damage was determined in real time during the tests by an optical extensometer called Videotraction. A modified constitutive equations, including strain rate and damage effects, are proposed, such a model is based on a non-equilibrium thermodynamic approach called (DNLR). The ability of the model to predict the complex nonlinear response of this polymer is examined by comparing the model simulation with the available experimental data, which demonstrate that this model can represent the deformation behavior of the polymer reasonably well. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=strain%20rate%20jump%20tests" title="strain rate jump tests">strain rate jump tests</a>, <a href="https://publications.waset.org/abstracts/search?q=volume%20strain" title=" volume strain"> volume strain</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20density%20polyethylene" title=" high density polyethylene"> high density polyethylene</a>, <a href="https://publications.waset.org/abstracts/search?q=large%20strain" title=" large strain"> large strain</a>, <a href="https://publications.waset.org/abstracts/search?q=thermodynamics%20approach" title=" thermodynamics approach"> thermodynamics approach</a> </p> <a href="https://publications.waset.org/abstracts/6857/experimental-investigation-and-constitutive-modeling-of-volume-strain-under-uniaxial-strain-rate-jump-test-in-hdpe" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6857.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">258</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">109</span> An UHPLC (Ultra High Performance Liquid Chromatography) Method for the Simultaneous Determination of Norfloxacin, Metronidazole, and Tinidazole Using Monolithic Column-Stability Indicating Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asmaa%20Mandour">Asmaa Mandour</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramzia%20El-Bagary"> Ramzia El-Bagary</a>, <a href="https://publications.waset.org/abstracts/search?q=Asmaa%20El-Zaher"> Asmaa El-Zaher</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehab%20Elkady"> Ehab Elkady</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: An UHPLC (ultra high performance liquid chromatography) method for the simultaneous determination of norfloxacin (NOR), metronidazole (MET) and tinidazole (TNZ) using monolithic column is presented. Purpose: The method is considered an environmentally friendly method with relatively low organic composition of the mobile phase. Methods: The chromatographic separation was performed using Phenomenex® Onyex Monolithic C18 (50mmx 20mm) column. An elution program of mobile phase consisted of 0.5% aqueous phosphoric acid : methanol (85:15, v/v). Where elution of all drugs was completed within 3.5 min with 1µL injection volume. The UHPLC method was applied for the stability indication of NOR in the presence of its acid degradation product ND. Results: Retention times were 0.69, 1.19 and 3.23 min for MET, TNZ and NOR, respectively. While ND retention time was 1.06 min. Linearity, accuracy, and precision were acceptable over the concentration range of 5-50µg mL-1for all drugs. Conclusions: The method is simple, sensitive and suitable for the routine quality control and dosage form assay of the three drugs and can also be used for the stability indication of NOR in the presence of its acid degradation product. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibacterial" title="antibacterial">antibacterial</a>, <a href="https://publications.waset.org/abstracts/search?q=monolithic%20cilumn" title=" monolithic cilumn"> monolithic cilumn</a>, <a href="https://publications.waset.org/abstracts/search?q=simultaneous%20determination" title=" simultaneous determination"> simultaneous determination</a>, <a href="https://publications.waset.org/abstracts/search?q=UHPLC" title=" UHPLC"> UHPLC</a> </p> <a href="https://publications.waset.org/abstracts/52684/an-uhplc-ultra-high-performance-liquid-chromatography-method-for-the-simultaneous-determination-of-norfloxacin-metronidazole-and-tinidazole-using-monolithic-column-stability-indicating-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52684.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">253</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">108</span> A Comparative, Epidemiological Study of Acute Renal Colic Presentations to Major Academic Emergency Departments in Doha, Qatar and Melbourne, Australia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sameer%20A.%20Pathan">Sameer A.

Methods: We undertook a retrospective cohort study of patients with renal colic who presented to the Hamad General Hospital Emergency Department (HGH-ED), Qatar, and The Alfred ED, Melbourne, Australia, during a period of one year from August 1, 2012, to July 3, 2013. Cases were identified using ICD-9-CM codes, and an electronic template was used to record the data on predefined clinical variables. Results: A total of 12,223 from the HGH-ED and 384 from The Alfred ED were identified as renal colic presentations during the study period. The rate of renal colic presentations at the HGH-ED was 27.9 per 1000 ED visits compared to 6.7 per 1000 ED visits at The Alfred ED. Patients presenting to the HGH-ED were significantly younger [34.9 years (29.0- 43.4) than The Alfred ED [48 years (37-60); P < 0.001]. The median stone size was larger in the HGH-ED group [6 (4-8) mm] versus The Alfred ED group [4 (3-6) mm, P < 0.001]. The intervention rate in the stone-positive population was significantly higher in the HGH-ED group as opposed to The Alfred ED group (38.7% versus 11.9%, p<0.001). At the time of discharge, The Alfred ED group received less analgesic prescriptions (55.8% versus 83.5%, P < 0.001) and more tamsulosin prescriptions (25.3% versus 11.7%, P < 0.001). Conclusions: Renal colic presentations to the HGH-ED, Qatar, were younger, with larger stone size, compared to The Alfred ED, whereas, medical expulsion therapy use was higher at the Alfred ED. Differences in epidemiology should be considered while tailoring strategies for effective management of patients with renal colic in the given setting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=kidney%20stones" title="kidney stones">kidney stones</a>, <a href="https://publications.waset.org/abstracts/search?q=urolithiasis" title=" urolithiasis"> urolithiasis</a>, <a href="https://publications.waset.org/abstracts/search?q=nephrolithiasis" title=" nephrolithiasis"> nephrolithiasis</a>, <a href="https://publications.waset.org/abstracts/search?q=renal%20colic" title=" renal colic"> renal colic</a>, <a href="https://publications.waset.org/abstracts/search?q=epidemiology" title=" epidemiology"> epidemiology</a> </p> <a href="https://publications.waset.org/abstracts/78021/a-comparative-epidemiological-study-of-acute-renal-colic-presentations-to-major-academic-emergency-departments-in-doha-qatar-and-melbourne-australia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78021.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">241</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">107</span> Histopathological and Biochemical Evaluation of Hydroxyurea-Induced Hepato-Pulmonary Toxicity and Lymphoid Necrosis in Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samah%20Oda">Samah Oda</a>, <a href="https://publications.waset.org/abstracts/search?q=Asmaa%20Khafaga"> Asmaa Khafaga</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Hashim"> Mohammed Hashim</a>, <a href="https://publications.waset.org/abstracts/search?q=Asmaa%20Khamis"> Asmaa Khamis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Toxicity of hydroxyurea (HU), a treatment for certain tumors, polycythemia, and thrombocytosis, was evaluated in rats in one-month toxicity study. Sixty male albino rats were equally classified into four groups. Rats received daily oral gavage of HU in 0, 250, 500, and 750 mg/kg b.wt. Chemical and histopathological assessment of liver, lung, spleen, and bone marrow was performed at 10, 20, and 30 days of the experiment. No significant change was reported in alanine aminotransferase (ALT), aspartate aminotransferase (AST), globulin, and albumin/ globulin ratio during the experiment. Significant decreases in alkaline phosphatase (ALP) and total albumin were reported in rats received 500 and 750 mg/kg b.wt of HU. In addition, total cholesterol level increased significantly after 10 days; however, it significantly decreased after 20 and 30 days of the experiment. Moreover, hepatocytic vacuolation and necrosis with portal inflammatory infiltrates were reported along experimental periods. Pulmonary congestion, hemorrhage, interstitial mononuclear infiltration, peribronchitis, and bronchial epithelial necrosis were also reported. Severe lymphocytic necrosis in spleen and severe loss of hematopoietic cells and replacement with corresponding adipose tissue in bone marrow tissues was demonstrated. In conclusion, HU could be able to induce severe dose and time-dependent hepato-pulmonary toxicity and lymphoid depression in rats. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydroxyurea" title="hydroxyurea">hydroxyurea</a>, <a href="https://publications.waset.org/abstracts/search?q=hepato-pulmonary%20toxicity" title=" hepato-pulmonary toxicity"> hepato-pulmonary toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=lymphoid%20depression" title=" lymphoid depression"> lymphoid depression</a>, <a href="https://publications.waset.org/abstracts/search?q=histopathology" title=" histopathology"> histopathology</a> </p> <a href="https://publications.waset.org/abstracts/99571/histopathological-and-biochemical-evaluation-of-hydroxyurea-induced-hepato-pulmonary-toxicity-and-lymphoid-necrosis-in-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99571.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">148</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">106</span> Simulation and Characterization of Organic Light Emitting Diodes and Organic Photovoltaics Using Physics Based Tool</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20A.%20Shahul%20Hameed">T.

Spectral measurements were performed in 565 samples, which were chosen randomly at the infection place in the potato slice. In this study, 254 infected and 311 uninfected (brown rot-free) samples were analyzed using different advanced statistical analysis techniques. The discrimination performance of different multivariate analysis techniques, including classification, pre-processing, and dimension reduction, were compared. Applying a random forest algorithm classifier with different pre-processing techniques to raw spectra had the best performance as the total classification accuracy of 98.7% was achieved in discriminating infected potatoes from control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brown%20rot%20disease" title="Brown rot disease">Brown rot disease</a>, <a href="https://publications.waset.org/abstracts/search?q=NIR%20spectroscopy" title=" NIR spectroscopy"> NIR spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=potato" title=" potato"> potato</a>, <a href="https://publications.waset.org/abstracts/search?q=random%20forest" title=" random forest"> random forest</a> </p> <a href="https://publications.waset.org/abstracts/127918/multivariate-analysis-of-spectroscopic-data-for-agriculture-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127918.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">190</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">95</span> Antibacterial Activity of Green Synthesis Silver Nanoparticles from Moringa Oleifera</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Fadhel%20Ahmed">Ali Fadhel Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Tuqa%20Abdulkareem%20Hameed"> Tuqa Abdulkareem Hameed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Moringa oleifera (leaves and seeds) ethanolic and aqueous extracts were tested for antibacterial activity.

The relatively high gene diversity and a relatively low random match probability were observed in Iraq population. The obtained data can be used to identify the variable nucleotide positions characterized by frequent occurrence which is most promising for various identifications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coding%20region" title="coding region">coding region</a>, <a href="https://publications.waset.org/abstracts/search?q=Iraq" title=" Iraq"> Iraq</a>, <a href="https://publications.waset.org/abstracts/search?q=mitochondrial%20DNA" title=" mitochondrial DNA"> mitochondrial DNA</a>, <a href="https://publications.waset.org/abstracts/search?q=polymorphic%20positions" title=" polymorphic positions"> polymorphic positions</a>, <a href="https://publications.waset.org/abstracts/search?q=sanger%20technique" title=" sanger technique"> sanger technique</a> </p> <a href="https://publications.waset.org/abstracts/2065/polymorphic-positions-haplotypes-and-mutations-detected-in-the-mitochonderial-dna-coding-region-by-sanger-sequence-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2065.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">437</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">92</span> Studying the Role of Teachers’ Self-Acceptance in the Development of Their Self-Esteem and Efficacy Level: A Case Study Applied to 37 Teachers at the English Department, Sidi Bel Abbes, Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asmaa%20Baghli">Asmaa Baghli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Self-acceptance is one of the most pertinent notions that attracted the attention of many scholars. These latters believed that the sense of self-acceptance for people contributes in the emergence of their self-esteem and helps to improve their efficacy level. Simply defined, self-acceptance stands for the ability of the person to admire and accept herself and her potentials. This fact is believed to participate in the personal image creation depending on the qualities and features possessed. Hitherto, the following paper aims, first, to provide a brief and concise definition of self-acceptance, self-esteem and self-efficacy. It tries to explain the correlation between the three concepts along with its linkage to language teaching. Then, it examines teachers’ acceptance level and its influence on their classroom actions. For that purpose, the main methodology undertaken is the mixed method. That means the combination between both quantitative and qualitative research methods. The prime tools selected are a questionnaire and self-acceptance test for teachers. Finally, it suggests some techniques for developing teachers’ self-acceptance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=competence" title="competence">competence</a>, <a href="https://publications.waset.org/abstracts/search?q=development" title=" development"> development</a>, <a href="https://publications.waset.org/abstracts/search?q=efficacy" title=" efficacy"> efficacy</a>, <a href="https://publications.waset.org/abstracts/search?q=Self-acceptance" title=" Self-acceptance"> Self-acceptance</a>, <a href="https://publications.waset.org/abstracts/search?q=self-esteem" title=" self-esteem"> self-esteem</a>, <a href="https://publications.waset.org/abstracts/search?q=teachers" title=" teachers"> teachers</a> </p> <a href="https://publications.waset.org/abstracts/123275/studying-the-role-of-teachers-self-acceptance-in-the-development-of-their-self-esteem-and-efficacy-level-a-case-study-applied-to-37-teachers-at-the-english-department-sidi-bel-abbes-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123275.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">141</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">91</span> Seed Germination and Recovery Responses of Suaeda Heterophylla to Abiotic Stresses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Hameed">Abdul Hameed</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Zaheer%20Ahmed"> Muhammad Zaheer Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Salman%20Gulzar"> Salman Gulzar</a>, <a href="https://publications.waset.org/abstracts/search?q=Bilquees%20Gul"> Bilquees Gul</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Alam"> Jan Alam</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20K.%20Hegazy"> Ahmad K.

The purpose of this paper is to study the structure of tourists’ shopping process to better understand their shopping behavior by investigating factors that influence this activity other than hotels tyranny. This study specifically aims to propose a model incorporating those all variables. This empirical study investigates the shopping experience of international tourists using a questionnaire aimed to examine multinational samples selected from the tourist population visiting a specific destination in Egypt. This study highlights the various stakeholders that make tourists do shop independent of hotels. The results, therefore, demonstrate the relationship between the shopping process entities involved and configure the variables within the model in a way that provides a viable solution for visitors to avoid the tyranny of hotel facilities and amenities on the public markets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hotels%E2%80%99%20amenities" title="hotels’ amenities">hotels’ amenities</a>, <a href="https://publications.waset.org/abstracts/search?q=shopping%20process" title=" shopping process"> shopping process</a>, <a href="https://publications.waset.org/abstracts/search?q=tourist%20behavior" title=" tourist behavior"> tourist behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=tourist%20satisfaction" title=" tourist satisfaction"> tourist satisfaction</a> </p> <a href="https://publications.waset.org/abstracts/122409/structure-of-tourists-shopping-behavior-from-the-tyranny-of-hotels-to-public-markets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122409.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">89</span> Indigenous Patch Clamp Technique: Design of Highly Sensitive Amplifier Circuit for Measuring and Monitoring of Real Time Ultra Low Ionic Current through Cellular Gates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Moez%20ul%20Hassan">Moez ul Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Bushra%20Noman"> Bushra Noman</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarmad%20Hameed"> Sarmad Hameed</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahab%20Mehmood"> Shahab Mehmood</a>, <a href="https://publications.waset.org/abstracts/search?q=Asma%20Bashir"> Asma Bashir </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The importance of Noble prize winning “Patch Clamp Technique” is well documented. However, Patch Clamp Technique is very expensive and hence hinders research in developing countries. In this paper, detection, processing and recording of ultra low current from induced cells by using transimpedence amplifier is described. The sensitivity of the proposed amplifier is in the range of femto amperes (fA). Capacitive-feedback is used with active load to obtain a 20MΩ transimpedance gain. The challenging task in designing includes achieving adequate performance in gain, noise immunity and stability. The circuit designed by the authors was able to measure current in the rangeof 300fA to 100pA. Adequate performance shown by the amplifier with different input current and outcome result was found to be within the acceptable error range. Results were recorded using LabVIEW 8.5®for further research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drug%20discovery" title="drug discovery">drug discovery</a>, <a href="https://publications.waset.org/abstracts/search?q=ionic%20current" title=" ionic current"> ionic current</a>, <a href="https://publications.waset.org/abstracts/search?q=operational%20amplifier" title=" operational amplifier"> operational amplifier</a>, <a href="https://publications.waset.org/abstracts/search?q=patch%20clamp" title=" patch clamp"> patch clamp</a> </p> <a href="https://publications.waset.org/abstracts/28042/indigenous-patch-clamp-technique-design-of-highly-sensitive-amplifier-circuit-for-measuring-and-monitoring-of-real-time-ultra-low-ionic-current-through-cellular-gates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28042.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">519</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">88</span> Effects of Unfamiliar Orthography on the Lexical Encoding of Novel Phonological Features</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asmaa%20Shehata">Asmaa Shehata</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Prior research indicates that second language (L2) learners encounter difficulty in the distinguishing novel L2 contrasting sounds that are not contrastive in their native languages. L2 orthographic information, however, is found to play a positive role in the acquisition of non-native phoneme contrasts. While most studies have mainly involved a familiar written script (i.e., the Roman script), the influence of a foreign, unfamiliar script is still unknown. Therefore, the present study asks: Does unfamiliar L2 script play a role in creating distinct phonological representations of novel contrasting phonemes? It is predicted that subjects’ performance in the unfamiliar orthography group will outperform their counterparts’ performance in the control group. Thus, training that entails orthographic inputs can yield a significant improvement in L2 adult learners’ identification and lexical encoding of novel L2 consonant contrasts. Results are discussed in terms of their implications for the type of input introduced to L2 learners to improve their language learning. <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=consonant%20contrasts" title=" consonant contrasts"> consonant contrasts</a>, <a href="https://publications.waset.org/abstracts/search?q=foreign%20script" title=" foreign script"> foreign script</a>, <a href="https://publications.waset.org/abstracts/search?q=lexical%20encoding" title=" lexical encoding"> lexical encoding</a>, <a href="https://publications.waset.org/abstracts/search?q=orthography" title=" orthography"> orthography</a>, <a href="https://publications.waset.org/abstracts/search?q=word%20learning" title=" word learning"> word learning</a> </p> <a href="https://publications.waset.org/abstracts/55226/effects-of-unfamiliar-orthography-on-the-lexical-encoding-of-novel-phonological-features" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55226.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">256</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">87</span> Retinal Vascular Tortuosity in Obstructive Sleep Apnea-COPD Overlap Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rabab%20A.%20El%20Wahsh">Rabab A.

Retinal microvasculature can be directly and non-invasively examined. Aim: to evaluate retinal vascular tortuosity in patients with COPD, OSA, and overlap syndrome. Subjects and method: Sixty subjects were included; 15 OSA patients, 15 COPD patients, 15 COPD-OSA overlap patients, and 15 matched controls. They underwent digital retinal photography, polysomnography, arterial blood gases, spirometry, ESS, and stop-bang questionnaires. Results: Tortuosity of most retinal vessels was higher in all patient groups compared to the control group; tortuosity was more marked in overlap syndrome. There was a negative correlation between tortuosity of retinal vessels and PO2, O2 saturation, and minimum O2 desaturation, and a positive correlation with PCO2, AHI, O2 desaturation index, BMI and smoking index. Conclusion: Retinal vascular tortuosity occurs in OSA, COPD and overlap syndrome. Retinal vascular tortuosity is correlated with arterial blood gases parameters, polysomnographic findings, smoking index and BMI. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=OSA" title="OSA">OSA</a>, <a href="https://publications.waset.org/abstracts/search?q=COPD" title=" COPD"> COPD</a>, <a href="https://publications.waset.org/abstracts/search?q=overlap%20syndrome" title=" overlap syndrome"> overlap syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=retinal%20vascular%20tortuosity" title=" retinal vascular tortuosity"> retinal vascular tortuosity</a> </p> <a href="https://publications.waset.org/abstracts/168040/retinal-vascular-tortuosity-in-obstructive-sleep-apnea-copd-overlap-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168040.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">75</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">86</span> The Effects of Watching Text-Relevant Video Segments with/without Subtitles on Vocabulary Development of Arabic as a Foreign Language Learners</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amirreza%20Karami">Amirreza Karami</a>, <a href="https://publications.waset.org/abstracts/search?q=Hawraa%20Nafea%20Hameed%20Alzouwain"> Hawraa Nafea Hameed Alzouwain</a>, <a href="https://publications.waset.org/abstracts/search?q=Freddie%20A.%20Bowles"> Freddie A.

Therefore, bridging the gap between humans and nature, the biophilia hypothesis emerges as a relatively theoretical and less comprehensively studied concept, though it has great potential for alternative design ideas. The research aims to enhance school playgrounds with biophilic design, positively impacting children's mental and physical well-being. This paper investigates the integration of biophilic design in school playgrounds and its influence on the well-being of children. It involves an analysis of three playgrounds in Alexandria, Egypt, each exhibiting varying degrees of biophilic design principles. The study investigates how these design elements enhance students' experiences by improving their surrounding environments. The research aims to develop a design framework and recommendations for creating or modifying playgrounds to enhance the physical and mental well-being of children. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biophilic%20design" title="biophilic design">biophilic design</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20health" title=" physical health"> physical health</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20well-being" title=" mental well-being"> mental well-being</a>, <a href="https://publications.waset.org/abstracts/search?q=children%E2%80%99s%20development" title=" children’s development"> children’s development</a>, <a href="https://publications.waset.org/abstracts/search?q=school%20playground" title=" school playground"> school playground</a> </p> <a href="https://publications.waset.org/abstracts/192052/enhancing-educational-environments-maximizing-school-playground-potential-through-biophilic-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192052.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">23</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">83</span> Chemical Profiling of Farsetia Aegyptia Turra and Farsetia Longisiliqua Decne. and Their Chemosystematic Significance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mona%20M.%20Marzouk">Mona M.

Amongst them, Farsetia aegyptia Turra and Farsetia longisiliqua Decne. are two common species characteristic to the Egyptian flora. The present study considers the first characterization of the chemical constituents of F. longisiliqua, aiming to compare with those identified from the medicinal species (F. aegyptia). Additionally, the chemosystematic relationships between the two studied species were evaluated and highlight the medicinal importance for F. longisiliqua. The chemical profiling of their aqueous methanol extracts were carried out using the LC-ESI-MS technique and afforded 54 compounds belonging to different chemical groups. Flavonoids are the major constituents and are represented by 32 compounds (two C-glycosyl flavone, four flavones, and 26 flavonols). Their structural variations and common constituents confirmed the chemosystematic significance of the two species. Moreover, the flavonoid profiles showed major common constituents between the two investigated species, which predicted the medicinal importance of F. longisiliqua. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brassicaceae" title="brassicaceae">brassicaceae</a>, <a href="https://publications.waset.org/abstracts/search?q=chemosystematics" title=" chemosystematics"> chemosystematics</a>, <a href="https://publications.waset.org/abstracts/search?q=farsetia" title=" farsetia"> farsetia</a>, <a href="https://publications.waset.org/abstracts/search?q=flavonoids" title=" flavonoids"> flavonoids</a>, <a href="https://publications.waset.org/abstracts/search?q=glucosinolates" title=" glucosinolates"> glucosinolates</a>, <a href="https://publications.waset.org/abstracts/search?q=LC-ESI-MS" title=" LC-ESI-MS"> LC-ESI-MS</a> </p> <a href="https://publications.waset.org/abstracts/131531/chemical-profiling-of-farsetia-aegyptia-turra-and-farsetia-longisiliqua-decne-and-their-chemosystematic-significance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131531.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">209</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">82</span> Investigation of the Capability of REALP5 to Solve Complex Fuel Geometry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20Abdelrazek">D.

Its results are compared to the results of PARET, a common code in thermal hydraulic analysis for research reactors, belonging to MTR-PC groups. The WWR-SM reactor at the Institute of Nuclear Physics (INP) in the Republic of Uzbekistan is simulated using both PARET and RELAP5 at steady state. Results from the two codes are compared. REALP5 code succeeded in solving the complex fuel geometry. The PARET code needed some calculations to obtain the final result. Although the final results from the PARET are more accurate, the small differences in both results makes using RELAP5 code recommended in case of complex fuel assemblies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=complex%20fuel%20geometry" title="complex fuel geometry">complex fuel geometry</a>, <a href="https://publications.waset.org/abstracts/search?q=PARET" title=" PARET"> PARET</a>, <a href="https://publications.waset.org/abstracts/search?q=RELAP5" title=" RELAP5"> RELAP5</a>, <a href="https://publications.waset.org/abstracts/search?q=WWR-SM%20reactor" title=" WWR-SM reactor"> WWR-SM reactor</a> </p> <a href="https://publications.waset.org/abstracts/4164/investigation-of-the-capability-of-realp5-to-solve-complex-fuel-geometry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4164.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">333</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">81</span> Ubiquitous Collaborative Mobile Learning (UCML): A Flexible Instructional Design Model for Social Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hameed%20Olalekan%20Bolaji">Hameed Olalekan Bolaji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The digital natives are driving the trends of literacy in the use of electronic devices for learning purposes. This has reconfigured the context of learning in the exploration of knowledge in a social learning environment. This study explores the impact of Ubiquitous Collaborative Mobile Learning (UCML) instructional design model in a quantitative designed-based research approach. The UCML model was a synergetic blend of four models that are relevant to the design of instructional content for a social learning environment. The UCML model serves as the treatment and instructions were transmitted via mobile device based on the principle of ‘bring your own device’ (BYOD) to promote social learning. Three research questions and two hypotheses were raised to guide the conduct of this study. A researcher-designed questionnaire was used to collate data and the it was subjected to reliability of Cronbach Alpha which yielded 0.91. Descriptive statistics of mean and standard deviation were used to answer research questions while inferential statistics of independent sample t-test was used to analyze the hypotheses. The findings reveal that the UCML model was adequately evolved and it promotes social learning its design principles through the use of mobile devices. <p class="card-text"><strong>Keywords:</strong>
