In Sudan, diabetic foot ulcer prevalence reached 18.1%. This study aims to assess the knowledge, attitudes, and practices and the correlation between the level of foot care knowledge and self-care practices among diabetic patients in Sudan. Methodology: In a cross-sectional study involving 262 patients with type 1 and type 2 diabetes attending diabetic clinics in three primary care centers in Khartoum, Sudan, during September to November 2022, information regarding participants sociodemographic status, foot care knowledge, attitudes, and practices was gathered using a validated, structured questionnaire in a face-to-face interview method. These data were analyzed using the statistical package for the social sciences (SPSS) 22. Results: The patients’ mean age was 54.9 years, with a female predominance (56%). Of the participants, 37% had diabetes mellitus for over ten years. On the topic of foot care, 35.5% of patients showed good knowledge, and 76% were aware of the risk of reduced foot sensation. In relation to nail care, only 19% knew how to cut nails correctly. Conclusion: Knowledge, attitudes, and practices about diabetic foot care are substandard. There is a positive correlation between foot care knowledge and self-care practices. Hence, educating diabetic patients with foot care knowledge through an awareness program and the characteristics of diabetic shoes may improve self-care practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DM" title="DM">DM</a>, <a href="https://publications.waset.org/abstracts/search?q=DFD" title=" DFD"> DFD</a>, <a href="https://publications.waset.org/abstracts/search?q=DFU" title=" DFU"> DFU</a>, <a href="https://publications.waset.org/abstracts/search?q=PHC" title=" PHC"> PHC</a>, <a href="https://publications.waset.org/abstracts/search?q=SPSS" title=" SPSS"> SPSS</a> </p> <a href="https://publications.waset.org/abstracts/173620/knowledge-attitude-and-practice-among-diabetic-patients-about-diabetic-foot-disease-in-khartoum-state-primary-health-care-centers-november-2022" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173620.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">73</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">75</span> Bee Colony Optimization Applied to the Bin Packing Problem</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kenza%20Aida%20Amara">Kenza Aida Amara</a>, <a href="https://publications.waset.org/abstracts/search?q=Bachir%20Djebbar"> Bachir Djebbar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We treat the two-dimensional bin packing problem which involves packing a given set of rectangles into a minimum number of larger identical rectangles called bins.

We show that the band gap of an armchair graphene nanoribbon may be tuned by introducing an appropriate periodic pattern of vacancies. The band gap changes in a zig-zag manner similar to the variation of the band gap of a graphene nanoribbon by changing its width. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AGNR" title="AGNR">AGNR</a>, <a href="https://publications.waset.org/abstracts/search?q=antidot" title=" antidot"> antidot</a>, <a href="https://publications.waset.org/abstracts/search?q=atomistic%20toolKit" title=" atomistic toolKit"> atomistic toolKit</a>, <a href="https://publications.waset.org/abstracts/search?q=vacancy" title=" vacancy"> vacancy</a> </p> <a href="https://publications.waset.org/abstracts/20917/effects-of-position-and-shape-of-atomic-defects-on-the-band-gap-of-graphene-nano-ribbon-superlattices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20917.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">1006</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">72</span> The Journey to Social Entrepreneurship: Profile Analysis of Social Enterprises in Morocco</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zeinab%20Hmama">Zeinab Hmama</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Much recent discourse has highlighted the supporting role of social entrepreneurs in solving social problems.

This friction can also cause damage to the piston material. Thus, the choice of an optimal material for the piston is necessary to improve the elastohydrodynamical contacts of the piston. In this study, to achieve this objective, an elastohydrodynamical lubrication model that satisfies the best tribological behavior of the piston with the optimum choice of material is developed. Several aluminum alloys composed of different components are studied in this simulation. An application is made on the piston 60 x 120 mm Diesel engine type F8L413 currently mounted on Deutz trucks TB230 by using different aluminum alloys where alloys based on aluminum-silicon have better tribological performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EHD%20lubricated%20contacts" title="EHD lubricated contacts">EHD lubricated contacts</a>, <a href="https://publications.waset.org/abstracts/search?q=friction" title=" friction"> friction</a>, <a href="https://publications.waset.org/abstracts/search?q=properties%20of%20materials" title=" properties of materials"> properties of materials</a>, <a href="https://publications.waset.org/abstracts/search?q=tribological%20performance" title=" tribological performance"> tribological performance</a> </p> <a href="https://publications.waset.org/abstracts/49879/enhancement-of-tribological-behavior-for-diesel-engine-piston-of-solid-skirt-by-an-optimal-choice-of-interface-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49879.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">272</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">70</span> Comparative Analysis of Spectral Estimation Methods for Brain-Computer Interfaces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rafik%20Djemili">Rafik Djemili</a>, <a href="https://publications.waset.org/abstracts/search?q=Hocine%20Bourouba"> Hocine Bourouba</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20C.%20Amara%20Korba"> M.

The results show that the different cases of floor configurations need some improvement to ensure the acoustic comfort in the receiving apartment. The recommended value of the impact sound level in the receiving room should not exceed 58 dB.

In this paper, nanowires of Copper and Copper oxide have been synthesized through a simple and time and cost-effective approach. The thermally grown Copper oxide nanowires have been converted into Copper nanowires through annealing in the Hydrogen atmosphere in a DC-PECVD system. To have a proper Copper nanostructure formation, an Au nanolayer was coated on the surface of Copper oxide nanowires. The results show the successful achievement of Copper nanowires without deformation or cracking.

Based on the concept of the orthogonal array, Taguchi method effectively reduces the number of tests required in an optimization process. Taguchi method has been successfully applied in many fields such as mechanical, chemical engineering, power electronics, etc. Compared to other evolutionary methods such as genetic algorithms, simulated annealing and particle swarm optimization, the Taguchi method is much easier to understand and implement. It requires less computational/iteration processing to optimize the problem. Different cases are considered to illustrate the performance of this technique. Simulation results show that this method outperforms the other evolution algorithms (like GA, PSO) for smart antenna systems design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=array%20factor" title="array factor">array factor</a>, <a href="https://publications.waset.org/abstracts/search?q=beamforming" title=" beamforming"> beamforming</a>, <a href="https://publications.waset.org/abstracts/search?q=null%20placement" title=" null placement"> null placement</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization%20method" title=" optimization method"> optimization method</a>, <a href="https://publications.waset.org/abstracts/search?q=orthogonal%20array" title=" orthogonal array"> orthogonal array</a>, <a href="https://publications.waset.org/abstracts/search?q=Taguchi%20method" title=" Taguchi method"> Taguchi method</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20antenna%20system" title=" smart antenna system"> smart antenna system</a> </p> <a href="https://publications.waset.org/abstracts/14589/linear-array-geometry-synthesis-with-minimum-sidelobe-level-and-null-control-using-taguchi-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14589.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">394</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">61</span> GIS for Simulating Air Traffic by Applying Different Multi-radar Positioning Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amara%20Rafik">Amara Rafik</a>, <a href="https://publications.waset.org/abstracts/search?q=Bougherara%20Maamar"> Bougherara Maamar</a>, <a href="https://publications.waset.org/abstracts/search?q=Belhadj%20Aissa%20Mostefa"> Belhadj Aissa Mostefa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Radar data is one of the many data sources used by ATM Air Traffic Management systems. These data come from air navigation radar antennas. These radars intercept signals emitted by the various aircraft crossing the controlled airspace and calculate the position of these aircraft and retransmit their positions to the Air Traffic Management System. For greater reliability, these radars are positioned in such a way as to allow their coverage areas to overlap. An aircraft will therefore be detected by at least one of these radars. However, the position coordinates of the same aircraft and sent by these different radars are not necessarily identical. Therefore, the ATM system must calculate a single position (radar track) which will ultimately be sent to the control position and displayed on the air traffic controller's monitor. There are several techniques for calculating the radar track. Furthermore, the geographical nature of the problem requires the use of a Geographic Information System (GIS), i.e. a geographical database on the one hand and geographical processing. The objective of this work is to propose a GIS for traffic simulation which reconstructs the evolution over time of aircraft positions from a multi-source radar data set and by applying these different techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ATM" title="ATM">ATM</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS" title=" GIS"> GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=radar%20data" title=" radar data"> radar data</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20traffic%20simulation" title=" air traffic simulation"> air traffic simulation</a> </p> <a href="https://publications.waset.org/abstracts/168613/gis-for-simulating-air-traffic-by-applying-different-multi-radar-positioning-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168613.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">85</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">60</span> The Relationship between Organizational Climate with Job Burnout and Job Satisfaction in Employees of Tehran Electric Company</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zeinab%20Amini%20Moghaddam">Zeinab Amini Moghaddam</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Dehkhodania"> Alireza Dehkhodania</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, organizations have found a high status in the cultural and social structures of societies.

Experiments were carried out on female mice given 175 ppm As2O3 in their drinking water from the 14th day of pregnancy until day 14 after delivery. Our results showed a significant decrease in plasma levels of total protein and albumin, cholesterol and triglyceride in As2O3 treated mice and their pups. The hyperbilirubinemia and the increased plasma total alkaline phosphatase activity suggested the presence of cholestasis. Transaminase activities as well as lactate deshydrogenase activity in plasma, known as biomarkers of hepatocellular injury, were elevated indicating hepatic cells’damage after treatment with As2O3. Exposure to arsenic led to an increase of liver thiobarbituric acid reactive substances level along with a concomitant decrease in the activities of superoxide dismutase, catalase and glutathione peroxidase and in glutathione. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20status" title="antioxidant status">antioxidant status</a>, <a href="https://publications.waset.org/abstracts/search?q=arsenic%20trioxide" title=" arsenic trioxide"> arsenic trioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=hepatotoxicity" title=" hepatotoxicity"> hepatotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=mice" title=" mice"> mice</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title=" oxidative stress"> oxidative stress</a> </p> <a href="https://publications.waset.org/abstracts/22776/hepatotoxicity-induced-by-arsenic-trioxide-in-adult-mice-and-their-progeny" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22776.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">255</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">58</span> Investigation of Solar Concentrator Prototypes under Tunisian Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Moncef%20Balghouthi">Moncef Balghouthi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Ben%20Amara"> Mahmoud Ben Amara</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdessalem%20Ben%20Hadj%20Ali"> Abdessalem Ben Hadj Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Amenallah%20Guizani"> Amenallah Guizani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Concentrated solar power technology constitutes an interesting option to meet a part of future energy demand, especially when considering the high levels of solar radiation and clearness index that are available particularly in Tunisia. In this work, we present three experimental prototypes of solar concentrators installed in the research center of energy CRTEn in Tunisia. Two are medium temperature parabolic trough solar collector used to drive a cooling installation and for steam generation. The third is a parabolic dish concentrator used for hybrid generation of thermal and electric power. Optical and thermal evaluations were presented. Solutions and possibilities to construct locally the mirrors of the concentrator were discussed. In addition, the enhancement of the performances of the receivers by nano selective absorption coatings was studied.

These data come from air navigation radar antennas. These radars intercept signals emitted by the various aircraft crossing the controlled airspace and calculate the position of these aircraft and retransmit their positions to the Air Traffic Management System. For greater reliability, these radars are positioned in such a way as to allow their coverage areas to overlap. An aircraft will therefore be detected by at least one of these radars. However, the position coordinates of the same aircraft and sent by these different radars are not necessarily identical. Therefore, the ATM system must calculate a single position (radar track) which will ultimately be sent to the control position and displayed on the air traffic controller's monitor. There are several techniques for calculating the radar track. Furthermore, the geographical nature of the problem requires the use of a Geographic Information System (GIS), i.e. a geographical database on the one hand and geographical processing. The objective of this work is to propose a GIS for traffic simulation which reconstructs the evolution over time of aircraft positions from a multi-source radar data set and by applying these different techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ATM" title="ATM">ATM</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS" title=" GIS"> GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=radar%20data" title=" radar data"> radar data</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/156884/geographic-information-system-for-simulating-air-traffic-by-applying-different-multi-radar-positioning-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156884.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">118</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">56</span> Enhancement Performance of Desalination System Using Humidification and Dehumidification Processes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zeinab%20Syed%20Abdel%20Rehim">Zeinab Syed Abdel Rehim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water shortage is considered as one of the huge problems the world encounter now. Water desalination is considered as one of the more suitable methods governments can use to substitute the increased need for potable water. The humidification-dehumidification process for water desalination is viewed as a promising technique for small capacity production plants. The process has several attraction features which include the use of sustainable energy sources, low technology, and low-temperature dehumidification. A pilot experimental set-up plant was constructed with the conventional HVAC components such as air blower that supplies air to an air duct inside which air preheater, steam injector and cooling coil of a small refrigeration unit are placed. The present work evaluates the characteristics of humidification-dehumidification process for water desalination as a function of air flow rate, total power input and air inlet temperature in order to study the optimum conditions required to produce distilled water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=condensation" title="condensation">condensation</a>, <a href="https://publications.waset.org/abstracts/search?q=dehumidification" title=" dehumidification"> dehumidification</a>, <a href="https://publications.waset.org/abstracts/search?q=evaporation" title=" evaporation"> evaporation</a>, <a href="https://publications.waset.org/abstracts/search?q=humidification" title=" humidification"> humidification</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20desalination" title=" water desalination"> water desalination</a> </p> <a href="https://publications.waset.org/abstracts/48084/enhancement-performance-of-desalination-system-using-humidification-and-dehumidification-processes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48084.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">243</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">55</span> A Study on Impact of Corporate Social Responsibility on Rural Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Amruth%20Raj">N.

Firms have been increasingly called upon to adopt strategies beyond the financial aspects of their operations and consider the social and environmental impact of their business activities. In this context, many companies have modified their policies and activities and engaged into Corporate Social Responsibility (CSR) especially on Rural development in India. At the firm level, CSR is implemented through various practices, which aim to enhance the company’s social and environmental performance and may cover various topics. Examples of CSR practices are abundant in Andhra Pradesh relevant literature. For instance, in India especially at Andhra Pradesh companies like Amara Raaja requires from its suppliers to prohibit child labour, Nagarjuna Cements applies a series of programs for reducing its CO2 emissions, LANCO group of Industries addresses health and safety issues in the workplace whereas GVK works limited has adopted a series of policies for addressing human rights and environmental abuse related to its operations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CSR" title="CSR">CSR</a>, <a href="https://publications.waset.org/abstracts/search?q=limitations" title=" limitations"> limitations</a>, <a href="https://publications.waset.org/abstracts/search?q=need" title=" need"> need</a>, <a href="https://publications.waset.org/abstracts/search?q=objectives" title=" objectives"> objectives</a>, <a href="https://publications.waset.org/abstracts/search?q=rural%20development" title=" rural development"> rural development</a> </p> <a href="https://publications.waset.org/abstracts/42318/a-study-on-impact-of-corporate-social-responsibility-on-rural-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42318.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">257</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">54</span> Correlation of Strength and Change in the Thickness of Back Extensor Muscles during Maximal Isometric Contraction in Healthy and Osteoporotic Postmenopausal Women</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Jan-Nataj%20Zeinab">Mohammad Jan-Nataj Zeinab</a>, <a href="https://publications.waset.org/abstracts/search?q=Kahrizi%20Sedighe"> Kahrizi Sedighe</a>, <a href="https://publications.waset.org/abstracts/search?q=Bayat%20Noshin"> Bayat Noshin</a>, <a href="https://publications.waset.org/abstracts/search?q=Giti%20Torkaman"> Giti Torkaman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> According to the importance of the back extensor muscle strength in postmenopausal women, this study aimed to determine the relationship between strength and changes in the thickness of back extensor muscles during isometric contraction in healthy and osteoporotic postmenopausal women.

HBV markers were tested in the sera of 3600 vaccinated children. Infected children were followed up for 1 year. Prevalence of HBV infection was 0.39 % (0.28% positive for anti-HBc, 0.03% positive for HBsAg and 0.08% positive for both). One year later, 50% of positive anti-HBc children turned negative with sustained positivity for positive HBsAg cases. HBV infection was significantly higher at age above 9 years (0.6%) compared to 0.2% at age 3-9 years and 0% at younger age (P < 0.05). Logistic analysis revealed that predictors for HBV infection were history of blood transfusion, regular medical injection, and family history of either HBV infection or drug abuse (adjusted odds ratios 6.2, 5.6, 7.6 & 19.1 respectively). HBV vaccination program produced adequate protection. Adherence to infection control measures and safe blood transfusion are recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HBV%20infection" title="HBV infection">HBV infection</a>, <a href="https://publications.waset.org/abstracts/search?q=HBV%20vaccine" title=" HBV vaccine"> HBV vaccine</a>, <a href="https://publications.waset.org/abstracts/search?q=children" title=" children"> children</a>, <a href="https://publications.waset.org/abstracts/search?q=Egypt" title=" Egypt"> Egypt</a> </p> <a href="https://publications.waset.org/abstracts/2352/hepatitis-b-virus-infection-among-egyptian-children-vaccinated-during-infancy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2352.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">444</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">52</span> The Pressure Effect and First-Principles Study of Strontium Chalcogenides SrS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benallou%20Yassine">Benallou Yassine</a>, <a href="https://publications.waset.org/abstracts/search?q=Amara%20Kadda"> Amara Kadda</a>, <a href="https://publications.waset.org/abstracts/search?q=Bouazza%20Boubakar"> Bouazza Boubakar</a>, <a href="https://publications.waset.org/abstracts/search?q=Soudini%20Belabbes"> Soudini Belabbes</a>, <a href="https://publications.waset.org/abstracts/search?q=Arbouche%20Omar"> Arbouche Omar</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Zemouli"> M.

In the same way, many research studied serious games (SGs) for various purposes such as classification, positive impacts, or learning outcomes. Although most of these research examine SG characteristics (SGCs) for conducting their studies, to author’s best knowledge, there is no consensus about features neither in number not in the description. In this paper, we conduct a literature review to collect essential game attributes regardless of the application areas and the study objectives. Firstly, we aimed to define Common SGCs (CSGCs) that characterize the game aspect, by gathering features having the same meanings. Secondly, we tried to identify specific features related to the application area or to the study purpose as a serious aspect. The findings suggest that any type of SG can be defined by a number of CSGCs depicting the gaming side, such as adaptability and rules. In addition, we outlined a number of specific SGCs describing the 'serious' aspect, including specific needs of the domain and indented outcomes. In conclusion, our review showed that it is possible to bridge the research gap due to the lack of consensus by using CSGCs. Moreover, these features facilitate the design and development of successful serious games in any domain and provide a foundation for further research in this area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=serious%20game%20characteristics" title="serious game characteristics">serious game characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=serious%20games%20common%20aspects" title=" serious games common aspects"> serious games common aspects</a>, <a href="https://publications.waset.org/abstracts/search?q=serious%20games%20features" title=" serious games features"> serious games features</a>, <a href="https://publications.waset.org/abstracts/search?q=serious%20games%20outcomes" title=" serious games outcomes"> serious games outcomes</a> </p> <a href="https://publications.waset.org/abstracts/108792/a-review-of-serious-games-characteristics-common-and-specific-aspects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108792.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">136</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">49</span> Study of the Antimicrobial Activity of the Extract of the Eucalyptus camaldulensis stemming from the Algerian Northeast</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meksem%20Nabila">Meksem Nabila</a>, <a href="https://publications.waset.org/abstracts/search?q=Bordjiba%20Ouahiba"> Bordjiba Ouahiba</a>, <a href="https://publications.waset.org/abstracts/search?q=Meraghni%20Messaouda"> Meraghni Messaouda</a>, <a href="https://publications.waset.org/abstracts/search?q=Meksem%20Amara%20Leila"> Meksem Amara Leila</a>, <a href="https://publications.waset.org/abstracts/search?q=Djebar%20Mohhamed%20Reda"> Djebar Mohhamed Reda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The problems of protection of the cultures are being more and more important that they interest great number of farmers and scientists because of the excessive use of the organic phytosanitary products of synthesis that causes fatal damages on the environment. To reduce the inconveniences produced by these pesticides, the use of "biopesticides" originated from plants could be an alternative. The aim of this work is the valuation of a botanical species: Eucalyptus camaldulensis from Northeastern Algeria which extracts are supposed to have an antimicrobial activity, similar to pesticides. The extraction of secondary metabolites from the leaves of E. camaldulensis was realized using methanol and water, and measurements of total polyphenols were made by spectrometric method. Determination of the antimicrobial activity of the extracts at issue was realized in vitro on phyto-pathogenic fungal and bacterial stumps. Tests of comparison were included in the essays by using the chemical pesticidal products of synthesis. The obtained results show that the plant contains polyphenols with an efficiency mattering of the order of 22 %. These polyphenols have a strong fungicidal and bactericidal pesticidal activity against various microbial stumps and the values of the zones of inhibition are more important compared with that obtained in the presence of the chemicals of synthesis (fungicide). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eucalyptus%20camaldulensis" title="eucalyptus camaldulensis">eucalyptus camaldulensis</a>, <a href="https://publications.waset.org/abstracts/search?q=biopesticide" title=" biopesticide"> biopesticide</a>, <a href="https://publications.waset.org/abstracts/search?q=polyphenols" title=" polyphenols"> polyphenols</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20activity" title=" antimicrobial activity"> antimicrobial activity</a> </p> <a href="https://publications.waset.org/abstracts/29478/study-of-the-antimicrobial-activity-of-the-extract-of-the-eucalyptus-camaldulensis-stemming-from-the-algerian-northeast" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29478.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">432</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">48</span> Identity Management in Virtual Worlds Based on Biometrics Watermarking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Bader">S.

Since access to these spaces is not restricted or controlled, some impostors take advantage of gaining unauthorized access and practicing cyber criminality. This paper proposes an identity management approach for securing access to virtual worlds. The major purpose of the suggested solution is to install a strong security mechanism to protect virtual identities represented by avatars. Thus, only legitimate users, through their corresponding avatars, are allowed to access the platform resources. Access is controlled by integrating an authentication process based on biometrics. In the request process for registration, a user fingerprint is enrolled and then encrypted into a watermark utilizing a cancelable and non-invertible algorithm for its protection. After a user personalizes their representative character, the biometric mark is embedded into the avatar through a watermarking procedure. The authenticity of the avatar identity is verified when it requests authorization for access. We have evaluated the proposed approach on a dataset of avatars from various virtual worlds, and we have registered promising performance results in terms of authentication accuracy, acceptation and rejection rates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=identity%20management" title="identity management">identity management</a>, <a href="https://publications.waset.org/abstracts/search?q=security" title=" security"> security</a>, <a href="https://publications.waset.org/abstracts/search?q=biometrics%20authentication%20and%20authorization" title=" biometrics authentication and authorization"> biometrics authentication and authorization</a>, <a href="https://publications.waset.org/abstracts/search?q=avatar" title=" avatar"> avatar</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20world" title=" virtual world"> virtual world</a> </p> <a href="https://publications.waset.org/abstracts/50268/identity-management-in-virtual-worlds-based-on-biometrics-watermarking" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50268.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">265</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">47</span> Early Detection of Kidney Failure by Using a Distinct Technique for Sweat Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saba.%20T.%20Suliman">Saba.

Sweat contains many elements that help in the diagnostic process. In this research, we analyzed sweat samples by using a Colorimeter device to identify the disease of kidney failure in its various stages. This analysis is a non-invasive method where the sample is collected from outside the body, and then this sample is analyzed. Urea refers to the disease of kidney failure when its quantity is high in the blood and then in the sweat, and by experience, we found that the amount of urea for males differs from its quantity for females, where there is a noticeable increase for males in normal and pathological cases. In this research, we took many samples from a normal group that does not suffer from renal failure and another who suffers from the disease to compare the percentage of urea, and after analysis, we found that the urea percentage is high in people with kidney failure disease. with an accuracy of results of 85%. <p class="card-text"><strong>Keywords:</strong> <a
