The research aim is to analyze the social presence in relation to two types of knowledge, declarative and procedural. Qualitative methodology has been used. The analysis of the contents was based on an observation protocol that included community of enquiry indicators and procedural and declarative knowledge indicators. The research has been conducted in three phases that focused on an observational protocol and indicators, results and conclusions. Results show that the teaching-learning processes have been characterized by the patterns of presence and types of knowledge. Results also show the importance of social presence support provided by the teacher and the students, not only in regard to the nature of the instructional support but also concerning how it is presented to the student and the importance that is attributed to it in the teaching-learning process, that is, what it is that assistance is offered on. In this study, we find that the presence based on procedural guidelines and declarative reflection, the management of shared meaning on the basis of the skills and the evidence of these skills entail patterns of learning. Nevertheless, the importance that the teacher attributes to each support aspect has a bearing on the extent to which the students reflect more on the given task. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=education" title="education">education</a>, <a href="https://publications.waset.org/abstracts/search?q=online" title=" online"> online</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching%20and%20learning%20processes" title=" teaching and learning processes"> teaching and learning processes</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge" title=" knowledge"> knowledge</a> </p> <a href="https://publications.waset.org/abstracts/44334/online-teaching-and-learning-processes-declarative-and-procedural-knowledge" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44334.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">216</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">5131</span> Detection of Lymphedema after Breast Cancer in Yucatecan Women</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olais%20A.%20Ingrid">Olais A.

The objective was to determine if there is presence of lymphedema secondary to breast cancer in Yucatecan women. It was an observational, analytical, cross-sectional study, 92 women were included who met the following criteria: women with surgical treatment for unilateral: breast cancer, aged between 25 and 65 years old, minimum 6 weeks after unilateral breast surgery and have completed any type of chemotherapy or adjuvant radiotherapy treatment for breast cancer. The evaluation was through indirect measurement volume by circometry to determine the presence of lymphedema. 23% of women had lymphedema grade I. It related to the presence of some of the symptoms like stiffness, swelling, decreased range of motion and feeling of heaviness in the arm of the operated side of the breast. It is important to determine the presence of lymphedema to perform physical therapy treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=lymphedema" title=" lymphedema"> lymphedema</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20therapy" title=" physical therapy"> physical therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=Yucatan" title=" Yucatan"> Yucatan</a> </p> <a href="https://publications.waset.org/abstracts/91249/detection-of-lymphedema-after-breast-cancer-in-yucatecan-women" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91249.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">349</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">5130</span> A Peer-Produced Community of Learning: The Case of Second-Year Algerian Masters Students at a Distance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nihad%20Alem">Nihad Alem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, distance learning (DL) is widely perceived as a reformed type of education that takes advantage of technology to give more appealing opportunities especially for learners whose life conditions impede their attendance to regular classrooms however, creating interactional environment for students to expand their learning community and alleviate the feeling of loneliness and isolation should receive more attention when designing a distance learning course. This research aims to explore whether the audio/video peer learning can offer pedagogical add-ons to the Algerian distance learners and what are the pros and cons of its application as an educational experience in a synchronous environment mediated by Skype. Data were collected using video recordings of six sessions, reflective logs, and in-depth semi-structured interviews and will be analyzed by qualitatively identifying and measuring the three constitutional elements of the educational experience of peer learning namely the social presence, the cognitive presence, and the facilitation presence using a modified community of inquiry coding template. The findings from this study will provide recommendations for effective peer learning educational experience using the facilitation presence concept. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=audio%2Fvisual%20peer%20learning" title="audio/visual peer learning">audio/visual peer learning</a>, <a href="https://publications.waset.org/abstracts/search?q=community%20of%20inquiry" title=" community of inquiry"> community of inquiry</a>, <a href="https://publications.waset.org/abstracts/search?q=distance%20learning" title=" distance learning"> distance learning</a>, <a href="https://publications.waset.org/abstracts/search?q=facilitation%20presence" title=" facilitation presence"> facilitation presence</a> </p> <a href="https://publications.waset.org/abstracts/115797/a-peer-produced-community-of-learning-the-case-of-second-year-algerian-masters-students-at-a-distance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115797.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">150</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">5129</span> The Relationship between Brand Recall and Brand Attitude in Advergame</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azaze-Azizi%20Abdul%20Adis">Azaze-Azizi Abdul Adis</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyung%20Jun%20Kim"> Hyung Jun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Rizwan%20Abdul%20Majid"> Mohamad Rizwan Abdul Majid</a>, <a href="https://publications.waset.org/abstracts/search?q=Zaiton%20Osman"> Zaiton Osman</a>, <a href="https://publications.waset.org/abstracts/search?q=Izyanti%20Awang%20Razli"> Izyanti Awang Razli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increase of online advertising, specifically advergame has become a popular method of strengthening consumer brand recognition by inserting attractive characters and enhancing entertainment value. There have been several remarkable studies on spokes-characters in advertising effectiveness. However, few studies have examined the link between character presence and consumers' brand recall and attitude in advergame. Moreover, how the entertainment value of an advergame influences brand recall and brand attitude and the mediating role of brand recall in influencing character presence and entertainment on brand attitude are still lacking in the advergaming literature. An online survey was conducted with 366 Malaysian gamers. Using structural equation modeling, the results showed that character presence had no influence but entertainment value had a positive influence on brand recall and brand attitude. This study confirmed the role of brand recall as a mediator of the effect of between entertainment and brand attitude in advergame. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=character%20presence" title="character presence">character presence</a>, <a href="https://publications.waset.org/abstracts/search?q=entertainment" title=" entertainment"> entertainment</a>, <a href="https://publications.waset.org/abstracts/search?q=brand%20recall" title=" brand recall"> brand recall</a>, <a href="https://publications.waset.org/abstracts/search?q=brand%20attitude" title=" brand attitude"> brand attitude</a>, <a href="https://publications.waset.org/abstracts/search?q=advergame" title=" advergame"> advergame</a> </p> <a href="https://publications.waset.org/abstracts/20513/the-relationship-between-brand-recall-and-brand-attitude-in-advergame" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20513.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">536</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">5128</span> Assessing Mobile Robotic Telepresence Based On Measures of Social Telepresence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Bagherzadhalimi">A.

The aim is to investigate how much the perception of system’s usefulness and ease of use is affected by operators’ sense of social telepresence (presence) in the remote location. Therefore, scenarios of visiting a museum are simulated and the user operators are supposed to perform some regular tasks inside the remote environment including interaction with local users, navigation and visiting the artworks. Participants were divided into two groups, those who had previous experience of operation and interaction with a MRP system and those who never had experience. Based on the results, both groups provided different feedbacks. Moreover, there was a significant association between user’s sense of presence and their perception of system usefulness and ease of use. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mobile%20robotic%20telepresence" title="mobile robotic telepresence">mobile robotic telepresence</a>, <a href="https://publications.waset.org/abstracts/search?q=museum" title=" museum"> museum</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20telepresence" title=" social telepresence"> social telepresence</a>, <a href="https://publications.waset.org/abstracts/search?q=usability%20test" title=" usability test"> usability test</a> </p> <a href="https://publications.waset.org/abstracts/15297/assessing-mobile-robotic-telepresence-based-on-measures-of-social-telepresence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15297.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">400</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">5127</span> Domain-Specific Deep Neural Network Model for Classification of Abnormalities on Chest Radiographs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nkechinyere%20Joy%20Olawuyi">Nkechinyere Joy Olawuyi</a>, <a href="https://publications.waset.org/abstracts/search?q=Babajide%20Samuel%20Afolabi"> Babajide Samuel Afolabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Bola%20Ibitoye"> Bola Ibitoye</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study collected a preprocessed dataset of chest radiographs and formulated a deep neural network model for detecting abnormalities. It also evaluated the performance of the formulated model and implemented a prototype of the formulated model. This was with the view to developing a deep neural network model to automatically classify abnormalities in chest radiographs. In order to achieve the overall purpose of this research, a large set of chest x-ray images were sourced for and collected from the CheXpert dataset, which is an online repository of annotated chest radiographs compiled by the Machine Learning Research Group, Stanford University. The chest radiographs were preprocessed into a format that can be fed into a deep neural network. The preprocessing techniques used were standardization and normalization. The classification problem was formulated as a multi-label binary classification model, which used convolutional neural network architecture to make a decision on whether an abnormality was present or not in the chest radiographs. The classification model was evaluated using specificity, sensitivity, and Area Under Curve (AUC) score as the parameter. A prototype of the classification model was implemented using Keras Open source deep learning framework in Python Programming Language. The AUC ROC curve of the model was able to classify Atelestasis, Support devices, Pleural effusion, Pneumonia, A normal CXR (no finding), Pneumothorax, and Consolidation. However, Lung opacity and Cardiomegaly had a probability of less than 0.5 and thus were classified as absent. Precision, recall, and F1 score values were 0.78; this implies that the number of False Positive and False Negative is the same, revealing some measure of label imbalance in the dataset. The study concluded that the developed model is sufficient to classify abnormalities present in chest radiographs into present or absent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transfer%20learning" title="transfer learning">transfer learning</a>, <a href="https://publications.waset.org/abstracts/search?q=convolutional%20neural%20network" title=" convolutional neural network"> convolutional neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=radiograph" title=" radiograph"> radiograph</a>, <a href="https://publications.waset.org/abstracts/search?q=classification" title=" classification"> classification</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-label" title=" multi-label"> multi-label</a> </p> <a href="https://publications.waset.org/abstracts/160741/domain-specific-deep-neural-network-model-for-classification-of-abnormalities-on-chest-radiographs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160741.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">129</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">5126</span> Microorganisms in Fresh and Stored Bee Pollen Originated from Slovakia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vladim%C3%ADra%20K%C5%88azovick%C3%A1">Vladimíra Kňazovická</a>, <a href="https://publications.waset.org/abstracts/search?q=M%C3%A1ria%20Dovi%C4%8Di%C4%8Dov%C3%A1"> Mária Dovičičová</a>, <a href="https://publications.waset.org/abstracts/search?q=Miroslava%20Ka%C4%8D%C3%A1niov%C3%A1"> Miroslava Kačániová</a>, <a href="https://publications.waset.org/abstracts/search?q=Margita%20%C4%8Canigov%C3%A1"> Margita Čanigová</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the study was to test the storage of bee pollen at room temperature and in cold store, and to describe microorganisms originated from it. Fresh bee pollen originating in West Slovakia was collected in May 2010. It was tested for presence of particular microbial groups using dilution plating method, and divided into two parts with different storage (in cold store and at room temperature). Microbial analyses of pollen were repeated after one year of storage. Several bacterial strains were isolated and tested using Gram staining, for catalase and fructose-6-phosphate-phosphoketolase presence, and by rapid ID 32A (BioMérieux, France). Micromycetes were identified at genus level. Fresh pollen contained coliform bacteria, which were not detected after one year of storage in both ways. Total plate count (TPC) of aerobes and anaerobes and of yeasts in fresh bee pollen exceeded 5.00 log CFU/g. TPC of aerobes and anaerobes decreased below 2.00 log CFU/g after one year of storage in both ways. Count of yeasts decreased to 2.32 log CFU/g (at room temperature) and to 3.66 log CFU/g (in cold store). Microscopic filamentous fungi decreased from 3.41 log CFU/g (fresh bee pollen) to 1.13 log CFU/g (at room temperature) and to 1.89 log CFU/g (in cold store). In fresh bee pollen, 12 genera of micromycetes were identified in the following order according to their relative density: Penicillium > Mucor > Absidia > Cladosporium, Fusarium > Alternaria > Eurotium > Aspergillus, Rhizopus > Emericella > Arthrinium and Mycelium sterilium. After one year at room temperature, only three genera were detected in bee pollen (Penicillium > Aspergillus, Mucor) and after one year in cold store, seven genera were detected (Mucor > Penicillium, Emericella > Aspergillus, Absidia > Arthrinium, Eurotium). From the plates designated for anaerobes, eight colonies originating in fresh bee pollen were isolated. Among them, a single yeast isolate occurred. Other isolates were G+ bacteria, with a total of five rod shaped. In three out of these five, catalase was absent and fructose-6-phosphate-phosphoketolase was present. Bacterial isolates originating in fresh pollen belonged probably to genus Bifidobacterium or relative genera, but their identity was not confirmed unequivocally. In general, cold conditions are suitable for maintaining the natural properties of foodstuffs for a longer time. Slight decrease of microscopic fungal number and diversity was recorded in cold temperatures compared with storage at room temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacteria" title="bacteria">bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=bee%20product" title=" bee product"> bee product</a>, <a href="https://publications.waset.org/abstracts/search?q=microscopic%20fungi" title=" microscopic fungi"> microscopic fungi</a>, <a href="https://publications.waset.org/abstracts/search?q=biosystems%20engineering" title=" biosystems engineering"> biosystems engineering</a> </p> <a href="https://publications.waset.org/abstracts/5155/microorganisms-in-fresh-and-stored-bee-pollen-originated-from-slovakia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5155.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">343</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">5125</span> Evaluation of Antioxidants in Medicinal plant Limoniastrum guyonianum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Assia%20Belfar">Assia Belfar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hadjadj"> Mohamed Hadjadj</a>, <a href="https://publications.waset.org/abstracts/search?q=Messaouda%20Dakmouche"> Messaouda Dakmouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Zineb%20Ghiaba"> Zineb Ghiaba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: This study aims to phytochemical screening; Extracting the active compounds and estimate the effectiveness of antioxidant in Medicinal plants desert Limoniastrum guyonianum (Zeïta) from South Algeria. Methods: Total phenolic content and total flavonoid content using Folin-Ciocalteu and aluminum chloride colorimetric methods, respectively. The total antioxidant capacity was estimated by the following methods: DPPH (1.1-diphenyl-2-picrylhydrazyl radical) and reducing power assay. Results: Phytochemical screening of the plant part reveals the presence of phenols, saponins, flavonoids and tannins. While alkaloids and Terpenoids were absent. The acetonic extract of L. guyonianum was extracted successively with ethyl acetate and butanol. Extraction of yield varied widely in the L. guyonianum ranging from (0.9425 %to 11.131%). The total phenolic content ranged from 53.33 mg GAE/g DW to 672.79 mg GAE/g DW. The total flavonoid concentrations varied from 5.45 to 21.71 mg/100g. IC50 values ranged from 0.02 ± 0.0004 to 0.13 ± 0.002 mg/ml. All extracts showed very good activity of ferric reducing power, the higher power was in butanol fraction (23.91 mM) more effective than BHA, BHT and VC. Conclusions: Demonstrated this study that the acetonic extract of L. guyonianum contain a considerable quantity of phenolic compounds and possess a good antioxidant activity. Can be used as an easily accessible source of Natural Antioxidants and as a possible food supplement and in the pharmaceutical industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=limoniastrum%20guyonianum" title="limoniastrum guyonianum">limoniastrum guyonianum</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolics%20compounds" title=" phenolics compounds"> phenolics compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=flavonoid%20compound" title=" flavonoid compound"> flavonoid compound</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title=" antioxidant activity"> antioxidant activity</a> </p> <a href="https://publications.waset.org/abstracts/38407/evaluation-of-antioxidants-in-medicinal-plant-limoniastrum-guyonianum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38407.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">346</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">5124</span> Comparative Study of Estimators of Population Means in Two Phase Sampling in the Presence of Non-Response</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syed%20Ali%20Taqi">Syed Ali Taqi</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ismail"> Muhammad Ismail</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A comparative study of estimators of population means in two phase sampling in the presence of non-response when Unknown population means of the auxiliary variable(s) and incomplete information of study variable y as well as of auxiliary variable(s) is made.

In middle and low countries like Ethiopia accessibility and quality of MCH service is low. During this COVID-19 Pandemics even the pervious access of MCH will be decreased. So many pregnant mothers are not attending their ANC, Delivery and other services in the hospital because they think they are more vulnerable to COVID-19. This condition may make an increase of maternal and neonatal morbidity and mortality. The innovation is an idea (which is development of a mobile app prepared by Maternity Foundation organization that focuses on midwifery care. The app has detailed videos on danger signs in pregnancy and procedures during labor and delivery). By telling this to clients it is planned to explore the perception, attitude towards this innovation and barriers to accepting it. What is planned to study is to explore the perceptions and barriers towards using of new idea which is innovation of mHealth on the MCH services. It is planned to interview the pregnant mothers who come for ANC at health facility and mothers who are absent from their appointment of services. In this way it is planned to explore how the mothers accept this idea and what barriers make them from accepting this idea. This is a phenomenological qualitative study and application of diffusion of innovation theory on the MCH services. The participant will be selected by using quota sampling methods for the mother who are interviewed at hospitals and snowball/quota sampling methods for the mother who are absent from their appointment/visits. Sample size of the participant depends on the saturation of data/idea. Each participant will be interviewed based the open-ended questionnaires, and the interview will be recorded then transcribed then finally analyzed by the open code 4.03. Beneficiaries: The federal ministry of health prepares them to develop the apk of mhealth. Health professionals in the MCH will have a low overload and accessibility and the quality of care will be increased during COVID-19 Different collaborations will be participated and promote the mother to enjoy the new idea. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title="COVID-19">COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=m%20health" title=" m health"> m health</a>, <a href="https://publications.waset.org/abstracts/search?q=MCH" title=" MCH"> MCH</a>, <a href="https://publications.waset.org/abstracts/search?q=diffusion%20of%20innovation" title=" diffusion of innovation"> diffusion of innovation</a> </p> <a href="https://publications.waset.org/abstracts/188788/using-of-m-health-in-mch-service-during-covid-19-application-of-diffusion-of-innovation-theory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188788.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">24</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">5121</span> Surveillance for African Swine Fever and Classical Swine Fever in Benue State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Asambe">A.

The sera collected were analysed using Indirect Enzyme Linked Immunosorbent Assay (ELISA) test kit to test for antibodies to ASFV, while competitive ELISA test kit was used to test for antibodies to CSFV. Of the 416 pigs from piggeries and 44 pigs sampled from the slaughter slab, seven (1.7%) and six (13.6%), respectively, tested positive to ASFV antibodies and was significantly associated (p < 0.0001). Out of the 12 LGAs sampled, Obi LGA had the highest ASFV antibody detection rate of (4.8%) and was significantly associated (p < 0.0001). None of the samples tested positive to CSFV antibodies. The study concluded that antibodies to CSFV were absent in the sampled pigs in piggeries and at the Makurdi central slaughter slab in Benue State, while antibodies to ASFV were present in both locations; hence, the need to keep an eye open for CSF too since both diseases may pose great risk in the study area. Further studies to characterise the ASFV circulating in Benue State and investigate the possible sources is recommended. Routine surveillance to provide a comprehensive and readily accessible data base to plan for the prevention of any fulminating outbreak is also recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=African%20swine%20fever" title="African swine fever">African swine fever</a>, <a href="https://publications.waset.org/abstracts/search?q=classical%20swine%20fever" title=" classical swine fever"> classical swine fever</a>, <a href="https://publications.waset.org/abstracts/search?q=piggery" title=" piggery"> piggery</a>, <a href="https://publications.waset.org/abstracts/search?q=slaughter%20slab" title=" slaughter slab"> slaughter slab</a>, <a href="https://publications.waset.org/abstracts/search?q=surveillance" title=" surveillance"> surveillance</a> </p> <a href="https://publications.waset.org/abstracts/79428/surveillance-for-african-swine-fever-and-classical-swine-fever-in-benue-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79428.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">5120</span> The Effect of Entertainment, Interactivity, and Authenticity Features of Tourism E-Commerce Live Streaming on Tourism Consumer’s Purchase Intention: The Mediating Role of Social Presence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Munir">Muhammad Munir</a>, <a href="https://publications.waset.org/abstracts/search?q=Moazzam"> Moazzam</a>, <a href="https://publications.waset.org/abstracts/search?q=Attia%20Saddique"> Attia Saddique</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Waheed"> Muhammad Waheed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study examines the complex interactions between entertainment, interaction, and authenticity aspects in the context of live streaming tourism e-commerce and how they affect tourists' intent to purchase. In the context of e-commerce live streaming, the goal of this study is to offer a thorough understanding of how these factors work together to influence consumers' intents to make purchases related to tourism. A sample of 250 respondents' information was gathered, and it was analyzed through Smart PLS 4. To ensure reliable measurement constructs, convergent and discriminant validity were evaluated. Discriminant validity was evaluated using the HTMT ratio approach, and the structural model was evaluated using structural equation modeling (SEM) with bootstrapping. Results showed that entertainment had a strong beneficial impact on social presence, highlighting the value of compelling content in raising users' sense of presence on live streaming platforms for tourism-related e-commerce.

Herein, we report multiple variations of the nerves of gluteal region. In the current case, the sciatic nerve was absent. The common peroneal and tibial nerves arose from sacral plexus and reached the gluteal region through greater sciatic foramen above and below piriformis respectively. The common peroneal nerve gave a muscular branch to the gluteus maximus. The inferior gluteal nerve and posterior cutaneous nerve of the thigh arose from a common trunk. The common trunk was formed by three roots. Upper and middle roots arose from sacral plexus and entered gluteal region through greater sciatic foramen respectively above and below piriformis. The lower root arose from the pudendal nerve and joined the common trunk. These variations were seen in the right gluteal region of an adult male cadaver aged approximately 70 years. Innervation of gluteus maximus by common peroneal nerve and presence of a common trunk of inferior gluteal nerve and posterior cutaneous nerve of the thigh make this case unique. The variant nerves may be subjected to iatrogenic injuries during surgical approach to the hip. They may also get compressed if there is a hypertrophy of the piriformis syndrome. Hence, the knowledge of these variations is of importance to clinicians, orthopedic surgeons and possibly for physiotherapists. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gluteal%20region" title="gluteal region">gluteal region</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20variations" title=" multiple variations"> multiple variations</a>, <a href="https://publications.waset.org/abstracts/search?q=nerve%20injury" title=" nerve injury"> nerve injury</a>, <a href="https://publications.waset.org/abstracts/search?q=sciatic%20nerve" title=" sciatic nerve"> sciatic nerve</a> </p> <a href="https://publications.waset.org/abstracts/30346/multiple-variations-of-the-nerves-of-gluteal-region-and-their-clinical-implications-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30346.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">343</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">5118</span> Impact of Lined and Unlined Water Bodies on the Distribution and Abundance of Fresh Water Snails in Certain Governorates in Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nahed%20Mohamed%20Ismail">Nahed Mohamed Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Bayomy%20Mostafa"> Bayomy Mostafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Abdel%20Kader"> Ahmed Abdel Kader</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Mohamed%20Azzam"> Ahmed Mohamed Azzam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Effect of lining watercourses on the distribution and abundance of fresh water snails at two Egyptian governorates, Baheria (new reclaimed area) and Giza was studied. Seasonal survey in lined and unlined sites during two successive years was carried out. Samples of snails and water were collected from each examined site and the ecological conditions were recorded. The collected snails from each site were placed in plastic aquaria and transferred to the laboratory, where they were sorted out, identified, counted and examined for natural infection. The size frequency distribution was calculated for each snail species. Results revealed that snails were represented in all examined watercourses (lined and unlined) at the two tested habitats by 14 species. (Biomphalaria alexandrina, B. glabrata, Bulinus truncatus, Physa acuta. Helisoma duryi, Lymnaea natalensis, Planorbis planorbis, Cleopatra bulimoids, Lanistes carinatus, Bellamya unicolor, Melanoides tuberculata, Theodoxus nilotica, Succinia cleopatra and Gabbiella senaarensis). During spring, the percentage of live (45%) and dead (55%) snail species was extremely highly significant lower (p>0.001) in lined water bodies compared to the unlined ones (93.5% and 6.5%, respectively) in the examined sites at Baheria. At Giza, the percentage values of live snail species from all lined watercourses (82.6% and 60.2%, during winter and spring, respectively) was significantly lower (p>0.05 & p>0.01) than those in unlined ones (91.1% and 79%, respectively). Size frequency distribution of snails collected from the lined and unlined water bodies at Baheria and Giza governorates during all seasons revealed that during survey, snail populations were stable and the recruitment of young to adult was continuing for some species, where the recruits were observed with adults. However, there was no sign of small snails occurrence in case of B. glabrata and B. alexandrina during autumn, winter and spring and disappear during summer at Giza. Meanwhile they completely absent during all seasons at Baheria Governorate. Chemical analysis of some heavy metals of water samples collected from lined and unlined sites from Baheria and Giza governorates during autumn, winter and spring were approximately as the same in both lined and unlined water bodies. However, Zn and Fe were higher in lined sites (0.78±0.37and 17.4 ± 4.3, respectively) than that of unlined ones (0.4±0.1 and 10.95 ± 1.93, respectively) and Cu was absent in both lined and unlined sites during summer at Baheria governorate. At Giza, Cu and Pb were absent and Fe were higher in lined sites (4.7± 4.2) than that of unlined ones (2.5 ± 1.4) during summer. Statistical analysis showed that no significant difference in all physico-chemical parameters of water in lined and unlined water bodies at the two tested habitats during all seasons. However, it was found that the water conductivity and TDS showed a lower mean values in lined sites than those of unlined ones. Thus, the present obtained data support the concept of utilizing environmental modification such as lining of water courses to help in minimizing the population density of certain vector snails and consequently reduce the transmission of snails born diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lining" title="lining">lining</a>, <a href="https://publications.waset.org/abstracts/search?q=fresh%20water" title=" fresh water"> fresh water</a>, <a href="https://publications.waset.org/abstracts/search?q=snails" title=" snails"> snails</a>, <a href="https://publications.waset.org/abstracts/search?q=watercourses" title=" watercourses"> watercourses</a> </p> <a href="https://publications.waset.org/abstracts/49502/impact-of-lined-and-unlined-water-bodies-on-the-distribution-and-abundance-of-fresh-water-snails-in-certain-governorates-in-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49502.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">254</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">5117</span> Territory and Well-Being: Qualitative Insights from the Morvan (Burgandy, France)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ga%C3%ABl%20Brul%C3%A9">Gaël Brulé</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The concept of territory seems to be largely absent from the literature on well-being. In the present study, the link between the territory and well-being is analyzed in the context of a rural area, the Morvan, in Burgundy (France). Through qualitative research-mostly interviews- this link is questioned and explored. The relationship between the territory and the actors inform us on several key-concepts often related to well-being: locus of control, mobility and identity. From an interactionist perspective, the relation between territory and actors seems to be a fertile ground to explore the latters’ well-being.

Therefore, this literature review built a body of knowledge of existing technology that can be used to improve immersiveness in VR. For this paper, "Sense of Presence (SoP)" was chosen as the terminology to describe immersiveness in VR. Eight studies that tested VR technologies were identified. Many other studies were included to back up the incentives behind these technologies. VR technologies include vibration, airflow, thermal components, EMS, and quadcopters. Study results from selected papers were analyzed, compared, and generally positive. Seven studies had positive results, and only one had negative results.

Using recent data on globalization for 88 countries (2000-2014), we examine whether the presence of a large section of youth exacerbates the negative effects of globalization, thereby increasing chances of civil unrest. Using recent measures of globalization, we find globalization affect adversely on the stability of a country. Our results indicate that globalization in the presence of a high youth unemployment rate can create more instability in an economy. Results are robust in the presence of other socio-economic variables. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=globalization" title="globalization">globalization</a>, <a href="https://publications.waset.org/abstracts/search?q=youth%20bulge" title=" youth bulge"> youth bulge</a>, <a href="https://publications.waset.org/abstracts/search?q=civil%20unrest" title=" civil unrest"> civil unrest</a>, <a href="https://publications.waset.org/abstracts/search?q=unemployment" title=" unemployment"> unemployment</a> </p> <a href="https://publications.waset.org/abstracts/116268/impact-of-globalization-on-youth-bulge-and-civil-unrest-an-empirical-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116268.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">154</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">5114</span> The Effects of Music and Gender on Recall Ability on College Students: A Study in Students from Universitas Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hestika%20D.%20Waraningrum">Hestika D.

The presence of a distraction is one of the environmental variables that affect recall ability in its capacity in the Short Term Memory. This study was made to see the difference in number of words that was successfully recalled by male participants and female participants with the presence of music as a distraction and also without music as a distraction. Data was taken using an experimental procedure from 75 female and male undergraduate students of Universitas Indonesia. The study design used was a 2x2 Factorial ANOVA, which aimed to see the difference between two variables, which were gender (male vs female) and the presence of a distraction (music serving as a distraction vs absence of music). The results indicated that there were no significant mean differences in the ability to recall between male and female participants. There are no significant mean differences between the presence and the absence of music as a distraction, but a significant interaction was found between gender and distraction with the ability to recall. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=college" title="college">college</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a>, <a href="https://publications.waset.org/abstracts/search?q=music" title=" music"> music</a>, <a href="https://publications.waset.org/abstracts/search?q=recall" title=" recall"> recall</a> </p> <a href="https://publications.waset.org/abstracts/91881/the-effects-of-music-and-gender-on-recall-ability-on-college-students-a-study-in-students-from-universitas-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91881.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">231</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">5113</span> Phi Thickening Induction as a Response to Abiotic Stress in the Orchid Miltoniopsis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nurul%20Aliaa%20Idris">Nurul Aliaa Idris</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20A.%20Collings"> David A. Collings</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Phi thickenings are specialized secondary cell wall thickenings that are found in the cortex of the roots in a wide range of plant species, including orchids. The role of phi thickenings in the root is still under debate through research have linked environmental conditions, particularly abiotic stresses such as water stress, heavy metal stress and salinity to their induction in the roots. It has also been suggested that phi thickenings may act as a barrier to regulate solute uptake, act as a physical barrier against fungal hyphal penetration due to its resemblance to the Casparian strip and play a mechanical role to support cortical cells. We have investigated phi thickening function in epiphytic orchids of the genus Miltoniopsis through induction experiment against factors such as soil compaction and water stress. The permeability of the phi thickenings in Miltoniopsis was tested through uptake experiments using the fluorescent tracer dyes Calcofluor white, Lucifer yellow and Propidium iodide then viewed with wide-field or confocal microscopy. To test whether phi thickening may prevent fungal colonization in the root cell, fungal re-infection experiment was conducted by inoculating isolated symbiotic fungus to sterile in vitro Miltoniopsis explants. As the movement of fluorescent tracers through the apoplast was not blocked by phi thickenings, and as phi thickenings developed in the roots of sterile cultures in the absence of fungus and did not prevent fungal colonization of cortical cells, the phi thickenings in Miltoniopsis do not function as a barrier. Phi thickenings were found to be absent in roots grown on agar and remained absent when plants were transplanted to moist soil. However, phi thickenings were induced when plants were transplanted to well-drained media, and by the application of water stress in all soils tested. It is likely that phi thickenings stabilize the root cortex during dehydration. Nevertheless, the varied induction responses present in different plant species suggest that the phi thickenings may play several adaptive roles, instead of just one, depending on species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abiotic%20stress" title="abiotic stress">abiotic stress</a>, <a href="https://publications.waset.org/abstracts/search?q=Miltoniopsis" title=" Miltoniopsis"> Miltoniopsis</a>, <a href="https://publications.waset.org/abstracts/search?q=orchid" title=" orchid"> orchid</a>, <a href="https://publications.waset.org/abstracts/search?q=phi%20thickening" title=" phi thickening"> phi thickening</a> </p> <a href="https://publications.waset.org/abstracts/96698/phi-thickening-induction-as-a-response-to-abiotic-stress-in-the-orchid-miltoniopsis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96698.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">146</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">5112</span> Investigating the Potential of VR in Language Education: A Study of Cybersickness and Presence Metrics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sakib%20Hasn">Sakib Hasn</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahid%20Anwar"> Shahid Anwar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study highlights the vital importance of assessing the Simulator Sickness Questionnaire and presence measures as virtual reality (VR) incorporation into language teaching gains popularity. To address user discomfort, which prevents efficient learning in VR environments, the measurement of SSQ becomes crucial. Additionally, evaluating presence metrics is essential to determine the level of engagement and immersion, both crucial for rich language learning experiences. This paper designs a VR-based Chinese language application and proposes a thorough test technique aimed at systematically analyzing SSQ and presence measures. Subjective tests and data analysis were carried out to highlight the significance of addressing user discomfort in VR language education. The results of this study shed light on the difficulties posed by user discomfort in VR language learning and offer insightful advice on how to improve VR language learning applications. Furthermore, the outcome of the research explores ‘VR-based language education,’ ‘inclusive language learning platforms," and "cross-cultural communication,’ highlighting the potential for VR to facilitate language learning across diverse cultural backgrounds. Overall, the analysis results contribute to the enrichment of language learning experiences in the virtual realm and underscore the need for continued exploration and improvement in this field. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=virtual%20reality%20%28VR%29" title="virtual reality (VR)">virtual reality (VR)</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20education" title=" language education"> language education</a>, <a href="https://publications.waset.org/abstracts/search?q=simulator%20sickness%20questionnaire" title=" simulator sickness questionnaire"> simulator sickness questionnaire</a>, <a href="https://publications.waset.org/abstracts/search?q=presence%20metrics" title=" presence metrics"> presence metrics</a>, <a href="https://publications.waset.org/abstracts/search?q=VR-based%20Chinese%20language%20education" title=" VR-based Chinese language education"> VR-based Chinese language education</a> </p> <a href="https://publications.waset.org/abstracts/181409/investigating-the-potential-of-vr-in-language-education-a-study-of-cybersickness-and-presence-metrics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181409.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">79</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">5111</span> Spectrofluorimetric Investigation of Copper (II), Cobalt (II), Calcium (II), and Ferric (III) Influence on the Ciprofloxacin Binding to Bovine Serum Albumin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20K.%20Youssef">Ahmed K.

The influence of Cu²⁺ Ca²⁺, Co²⁺, and Fe³⁺ on the Cip-BSA interaction was investigated. The quenching of the BSA fluorescence emission in presence of ciprofloxacin as well as the influence of metal ions on the interaction was analyzed using the Stern-Volmer equation. The Stern-Volmer quenching constant, Kₛᵥ was calculated in presence and absence of the metal ions at the physiological pH of 7.4 using phosphate buffer. The experimental results showed that interaction mainly static in nature and quenching rate constant is decreased in presence of the studied metal ions with exception of Cu²⁺ ions. The decrease observed in the Kₛᵥ values in presence of Co²⁺, Ca²⁺, and Fe³⁺ can be understood on basis of competition between these metal and Cip when both of them existed in the BSA solution. Cu²⁺ induces interaction between Cip and BSA at faster quenching rates as inferred from the observed increase in the Kₛᵥ value. This allowed us to propose that copper (II) ions are directly involved in the process of Cip binding to BSA. The binding constant for Cip on BSA was determined and the metal ions effect on it was examined as well and their values were in line with the Kₛᵥ values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bovine%20serum%20albumin" title="bovine serum albumin">bovine serum albumin</a>, <a href="https://publications.waset.org/abstracts/search?q=ciprofloxacin" title=" ciprofloxacin"> ciprofloxacin</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorescence" title=" fluorescence"> fluorescence</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20ions%20effect" title=" metal ions effect"> metal ions effect</a> </p> <a href="https://publications.waset.org/abstracts/97969/spectrofluorimetric-investigation-of-copper-ii-cobalt-ii-calcium-ii-and-ferric-iii-influence-on-the-ciprofloxacin-binding-to-bovine-serum-albumin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97969.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">392</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">5110</span> Effect of Retained Posterior Horn of Medial Meniscus on Functional Outcome of ACL Reconstructed Knees</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kevin%20Syam">Kevin Syam</a>, <a href="https://publications.waset.org/abstracts/search?q=Devendra%20K.%20Chauhan"> Devendra K.

Cadaveric studies have revealed increased strain on the ACL graft and greater instrumented laxity in Posterior horn deficient knees. Clinical studies have shown higher prevalence of radiological OA after ACL reconstruction combined with menisectomy. However, functional outcomes in ACL reconstructed knee in the absence of Posterior horn is less discussed, and specific role of posterior horn is ill-documented. This study evaluated functional and radiological outcomes in posterior horn preserved and posterior horn sacrificed ACL reconstructed knees. Materials: Of the 457 patients who had ACL reconstruction done over a 6 year period, 77 cases with minimum follow up of 18 months were included in the study after strict exclusion criteria (associated lateral meniscus injury, other ligamentous injuries, significant cartilage degeneration, repeat injury and contralateral knee injuries were excluded). 41 patients with intact menisci were compared with 36 patients with absent posterior horn of medial meniscus. Radiological and clinical tests for instability were conducted, and knees were evaluated using subjective International Knee Documentation Committee (IKDC) score and the Orthopadische Arbeitsgruppe Knie score (OAK). Results: We found a trend towards significantly better overall outcome (OAK) in cases with intact PHMM at average follow-up of 43.03 months (p value 0.082). Cases with intact PHMM had significantly better objective stability (p value 0.004). No significant differences were noted in the subjective IKDC score (p value 0.526) and the functional OAK outcome (category D) (p value 0.363). More cases with absent posterior horn had evidence of radiological OA (p value 0.022) even at mid-term follow-up. Conclusion: Even though the overall OAK and subjective IKDC scores did not show significant difference between the two subsets, the poorer outcomes in terms of objective stability and radiological OA noted in the absence of PHMM, indicates the importance of preserving this important part of the meniscus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ACL" title="ACL">ACL</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20outcome" title=" functional outcome"> functional outcome</a>, <a href="https://publications.waset.org/abstracts/search?q=knee" title=" knee"> knee</a>, <a href="https://publications.waset.org/abstracts/search?q=posterior%20of%20medial%20meniscus" title=" posterior of medial meniscus"> posterior of medial meniscus</a> </p> <a href="https://publications.waset.org/abstracts/23572/effect-of-retained-posterior-horn-of-medial-meniscus-on-functional-outcome-of-acl-reconstructed-knees" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23572.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">359</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">5109</span> Visualized Flow Patterns around and inside a Two-Sided Wind-Catcher in the Presence of Upstream Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Afshin">M.

Wind-catchers are an important part of natural ventilation in residential buildings or public places such as shopping centers, libraries, etc. Wind-catchers might be also used in places of high urban densities; hence their potential to provide natural ventilation in this case is dependent on the presence of upstream objects. In this study, the two-sided wind-catcher model was based on a real wind-catcher observed in the city of Yazd, Iran. The present study focuses on the flow patterns inside and outside the isolated two-sided wind-catcher, and on a two-sided wind-catcher in the presence of an upstream structure. The results show that the presence of an upstream structure influences the airflow pattern force and direction. Placing a high upstream object reverses the airflow direction inside the wind-catcher. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=natural%20ventilation" title="natural ventilation">natural ventilation</a>, <a href="https://publications.waset.org/abstracts/search?q=smoke%20flow%20visualization" title=" smoke flow visualization"> smoke flow visualization</a>, <a href="https://publications.waset.org/abstracts/search?q=two-sided%20wind-catcher" title=" two-sided wind-catcher"> two-sided wind-catcher</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20patterns" title=" flow patterns"> flow patterns</a> </p> <a href="https://publications.waset.org/abstracts/16978/visualized-flow-patterns-around-and-inside-a-two-sided-wind-catcher-in-the-presence-of-upstream-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16978.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">573</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">5108</span> Catalytic Deoxygenation of Propionic Acid in the Vapour Phase</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Bayahia">Hossein Bayahia</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Saad%20Motlaq%20Al-Gahmdi"> Mohammed Saad Motlaq Al-Gahmdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The gas-phase deoxygenation of propionic acid was investigated in the presence of Co-Mo catalysts in N2 or H2 flow at 200-400 °C.

Different methods have been tried to degrade or treat the effluent before it is left to the environment. In order to understand the degradation process and later apply it to effluents, solar degradation study of methylene blue (MB) and methyl red (MR), the model dyes was carried out in the presence of photo-catalysts, the oxides of cobalt oxide Co₃O₄, and copper doped cobalt oxides (Co₀.₉Cu₀.₁)₃O₄ and (Co₀.₉₅Cu₀.₀₅)₃O₄. They were prepared from oxalate complex and hydrazinated oxalate complex of cobalt as well as mix metals, copper, and cobalt. The complexes were synthesized and characterized by FTIR. Complexes were decomposed to form oxides and were characterized by XRD. They were found to be monophasic. Solar degradation of MR and MB was carried out in presence of these oxides in acidic and basic medium. Degradation was faster in alkaline medium in the presence of Co₃O₄ obtained from hydrazinated oxalate. Doping of nanomaterial oxides modifies their characteristics. Doped cobalt oxides are found to photo-decolourise MR in alkaline media efficiently. In the absence of photocatalyst, solar degradation of alkaline MR does not occur. In acidic medium, MR is minimally decolorized even in the presence of photocatalysts. The industrial textile effluent contains chemicals like NaCl and Na₂CO₃ along with the unabsorbed dye. It is reported that these two chemicals hamper the degradation of dye. The chemicals like K₂S₂O₈ and H₂O₂ are reported to enhance degradation. The solar degradation study of MB in presence of photocatalyst (Co₀.₉Cu₀.₁)₃O₄ and these four chemicals reveals that presence of K₂S₂O₈ and H₂O₂ enhances degradation. It proves that H₂O₂ generates hydroxyl ions required for degradation of dye and the sulphate anion radical being strong oxidant attacks dye molecules leading to its fragmentation rapidly.

The primary objective of this paper is to propose a methodology for quantitative analysis of neural-nets associated with these mental activities in the neocortex. The secondary objective of this paper is to suggest a methodology for quantitative analysis of presence; the proposed methodologies can be used as a first-step to measure, monitor, and understand consciousness and presence. This methodology is based on Neural-Networks (NN), number of neuron in each NN associated with consciousness, subconsciouness, and unconsciousness, and number of neurons in neocortex. It is assumed that the number of neurons in each NN is correlated with the associated area and volume. Therefore, online and offline visualization techniques can be used to identify these neural-networks, and online and offline measurement methods can be used to measure areas and volumes associated with these NNs. So, instead of the number of neurons in each NN, the associated area or volume also can be used in the proposed methodology. This quantitative analysis and associated online and offline measurements and visualizations of different Neural-Networks enable us to rewire the connections in our brain for a more balanced living. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brain" title="brain">brain</a>, <a href="https://publications.waset.org/abstracts/search?q=mind" title=" mind"> mind</a>, <a href="https://publications.waset.org/abstracts/search?q=consciousness" title=" consciousness"> consciousness</a>, <a href="https://publications.waset.org/abstracts/search?q=presence" title=" presence"> presence</a>, <a href="https://publications.waset.org/abstracts/search?q=sub-consciousness" title=" sub-consciousness"> sub-consciousness</a>, <a href="https://publications.waset.org/abstracts/search?q=unconsciousness" title=" unconsciousness"> unconsciousness</a>, <a href="https://publications.waset.org/abstracts/search?q=skills" title=" skills"> skills</a>, <a href="https://publications.waset.org/abstracts/search?q=concentrations" title=" concentrations"> concentrations</a>, <a href="https://publications.waset.org/abstracts/search?q=attention" title=" attention"> attention</a> </p> <a href="https://publications.waset.org/abstracts/36224/quantitative-analysis-of-presence-consciousness-subconsciousness-and-unconsciousness" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36224.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">314</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5105</span> Extracting the Antioxidant Compounds of Medicinal Plant Limoniastrum guyonianum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Assia%20Belfar">Assia Belfar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hadjadj"> Mohamed Hadjadj</a>, <a href="https://publications.waset.org/abstracts/search?q=Messaouda%20Dakmouche"> Messaouda Dakmouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Zineb%20Ghiaba"> Zineb Ghiaba</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Belguidoum"> Mahdi Belguidoum</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: This study aims to phytochemical screening; Extracting the active compounds and estimate the effectiveness of antioxidant in Medicinal plants desert Limoniastrum guyonianum (Zeïta) from South Algeria.

Whereas in this location, the carbonate sandstone of Sambipitu Formation (early-middle Miocene) is well exposed along Ngalang River, also there are ichnofossil presence which causes this formation to be interesting. The determination of paleobathymetry is particularly important in determining paleoenvironment and paleogeographic. Paleobathymetry can be determined by identifying the presence of Foraminifera bentonik fossil and parasequence emerge. The methods that used in this study are spatial method of field observation with systematic sampling, descriptive method of paleontology, biostratigraphy analysis, geometrical analysis of Ichnofossil, and study literature. The result obtained that paleobathymetry of this location is bathyal zone with maximum regression known by Bulliminoides williamsonianus showing depth 17 fathoms at the age of N3-N5 (Oligocenne-Early Miocene) and the maximum transgression is known by Cibicides pseudoungarianus showing depth 862 fathoms at the age of N8-N9 (Early-Middle Miocene).

Sulochana Singha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dhiyan or Dehan is the name of the community and language spoken by the Koch-Rajbangshi people of Barak Valley of Assam. Ethnically, they are Mongoloids, and their language belongs to the Indo-Aryan language family. However, Dhiyan is absent in any classification of Indo-Aryan languages. So the classification of Dhiyan language under the Indo-Aryan language family is completely based on the shared typological features of the other Indo-Aryan languages. Typologically, Dhiyan is an agglutinating language, and it shares many features of Indo-Aryan languages like presence of aspirated voiced stops, non-tonal, verb-person agreement, adjectives as different word class, prominent tense and subject object verb word order. Reduplication is a productive word-formation process in Dhiyan. Besides it also expresses plurality, intensification, and distributive. Generally, reduplication in Dhiyan can be at the morphological or lexical level. Morphological reduplication in Dhiyan involves expressives which includes onomatopoeias, sound symbolism, idiophones, and imitatives. Lexical reduplication in the language can be formed by echo formations and word reduplication. Echo formation in Dhiyan is formed by partial repetition from the base word which can be either consonant alternation or vowel alternation. The consonant alternation is basically found in onset position while the alternation of vowel is basically found in open syllable particularly in final syllable. Word reduplication involves reduplication of nouns, interrogatives, adjectives, and numerals which further can be class changing or class maintaining reduplication. The process of reduplication can be partial or complete whether it is lexical or morphological. The present paper is an attempt to describe some aspects of the formation, function, and usage of reduplications in Dhiyan which is mainly spoken in ten villages in the Eastern part of Barak River in the Cachar District of Assam. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Barak-Valley" title="Barak-Valley">Barak-Valley</a>, <a
