We determine how the temperature affects mobility when the electric potential is applied. For this, a theoretical approach based on mobility in a p-type Silicon piezoresistor with that of a finite difference model for self-heating is developed. So, the evolution of mobility has been established versus time for different doping levels and with temperature rise provoked by self-heating using a numerical model combined with that of mobility. Furthermore, it has been calculated for some geometrical parameters of the sensor, such as membrane side length and thickness. Also, it is computed as a function of bias voltage. It was observed that mobility is strongly affected by the temperature rise induced by the applied potential when the sensor is actuated for a prolonged time as a consequence of drifting in the output response of the sensor. Finally, this work makes it possible to predict their temperature behavior due to self-heating and to improve this effect by optimizing the geometric properties of the device and by reducing the voltage source applied to the bridge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sensors" title="Sensors">Sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=Piezoresistivity" title=" Piezoresistivity"> Piezoresistivity</a>, <a href="https://publications.waset.org/abstracts/search?q=Mobility" title=" Mobility"> Mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=Bias%20voltage" title=" Bias voltage"> Bias voltage</a> </p> <a href="https://publications.waset.org/abstracts/159683/numerical-investigation-including-mobility-model-for-the-performances-of-piezoresistive-sensors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159683.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">92</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Compost Enriched with Actinomyces and Bacillus Polymyxa Algae as a Partial Substitute for Mineral N in Ewaise Mango Orchards</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelaziz%20Sheba%20Abdelrahman">Abdelaziz Sheba Abdelrahman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Compost enriched with actinomyces and Bacillus polymyxa algae as a Partial Substitute for Mineral N in Ewaise Mango Orchards Organic fertiliser, compost enriched with actinomyces, and the biofertilizer Bacillus polymyxa algae were used as a partial replacement for mineral N fertiliser in Ewaise mango orchards during the 2019 and 2020 seasons. When compared to using mineral N alone, the results showed that reducing the percentage of mineral N fertiliser from 100 to 50% and using compost enriched with actinomyces at 25 to 50% and Bacillus polymyxa had an announced promotion on leaf area, total chlorophylls, leaf N, P, and K, yield, and fruit quality. The use of compost enriched with actinomyces and Bacillus polymyxa, as well as mineral N, resulted in a significant decrease in nitrite in the pulp. Reducing mineral N to 25% of the suitable N had a negative impact on yield. The application of appropriate N via 50% inorganic N + compost enriched with actinomyces at 50% + Bacillus polymyxa algae increased yield quantitatively and qualitatively in Ewaise mango orchards.

This ensures they can react quickly when needed. A study was conducted to develop a way to locate and track materials on construction sites. The system is an RFID/GPS integration that's required to pull off this feat. The study also reports how the platform has been used in construction. They found many advantages to using it, including reductions in both time and costs as well as improved management of materials orders. . For example, the time in which a project could start up was shortened from two weeks to three days with just a single digital order. As of now, the technology is still limited in its widespread adoption due largely to overall lack of awareness and difficulty connecting to it. However, as more and more companies embrace it in construction, the technology is expected to become ubiquitous. The developed platform provides contractors and construction managers with real-time information about the status of materials and work, allowing them to better manage the workflow in a project. The study sheds new light on this subject, which is essential to know. This work is becoming increasingly aware of the use of smart tools in constructing buildings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=materials%20management" title="materials management">materials management</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20of%20things%20%28IoT%29" title=" internet of things (IoT)"> internet of things (IoT)</a>, <a href="https://publications.waset.org/abstracts/search?q=radio%20frequency%20identification%20%28RFID%29" title=" radio frequency identification (RFID)"> radio frequency identification (RFID)</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20site" title=" construction site"> construction site</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain%20management" title=" supply chain management"> supply chain management</a> </p> <a href="https://publications.waset.org/abstracts/150430/radio-frequency-identification-rfid-cost-effective-location-based-system-for-managing-construction-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150430.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">81</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">38</span> Application of Adaptive Neuro Fuzzy Inference Systems Technique for Modeling of Postweld Heat Treatment Process of Pressure Vessel Steel AASTM A516 Grade 70</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omar%20Al%20Denali">Omar Al Denali</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelaziz%20Badi"> Abdelaziz Badi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ASTM A516 Grade 70 steel is a suitable material used for the fabrication of boiler pressure vessels working in moderate and lower temperature services, and it has good weldability and excellent notch toughness. The post-weld heat treatment (PWHT) or stress-relieving heat treatment has significant effects on avoiding the martensite transformation and resulting in high hardness, which can lead to cracking in the heat-affected zone (HAZ). An adaptive neuro-fuzzy inference system (ANFIS) was implemented to predict the material tensile strength of post-weld heat treatment (PWHT) experiments. The ANFIS models presented excellent predictions, and the comparison was carried out based on the mean absolute percentage error between the predicted values and the experimental values. The ANFIS model gave a Mean Absolute Percentage Error of 0.556 %, which confirms the high accuracy of the model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=prediction" title="prediction">prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=post-weld%20heat%20treatment" title=" post-weld heat treatment"> post-weld heat treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptive%20neuro-fuzzy%20inference%20system" title=" adaptive neuro-fuzzy inference system"> adaptive neuro-fuzzy inference system</a>, <a href="https://publications.waset.org/abstracts/search?q=mean%20absolute%20percentage%20error" title=" mean absolute percentage error"> mean absolute percentage error</a> </p> <a href="https://publications.waset.org/abstracts/148849/application-of-adaptive-neuro-fuzzy-inference-systems-technique-for-modeling-of-postweld-heat-treatment-process-of-pressure-vessel-steel-aastm-a516-grade-70" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148849.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">153</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">37</span> Dysbiosis of the Intestinal Microbiome in Colorectal Cancer Patients at Hospital of Amizour, Bejaia, Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adjebli%20Ahmed">Adjebli Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Messis%20Abdelaziz"> Messis Abdelaziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayeche%20Riad"> Ayeche Riad</a>, <a href="https://publications.waset.org/abstracts/search?q=Tighilet%20Karim"> Tighilet Karim</a>, <a href="https://publications.waset.org/abstracts/search?q=Talbi%20Melissa"> Talbi Melissa</a>, <a href="https://publications.waset.org/abstracts/search?q=Smaili%20Yanis"> Smaili Yanis</a>, <a href="https://publications.waset.org/abstracts/search?q=Lehri%20Mokrane"> Lehri Mokrane</a>, <a href="https://publications.waset.org/abstracts/search?q=Louardiane%20Mustapha"> Louardiane Mustapha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Colorectal cancer is one of the most common types of cancer worldwide, and its incidence has been increasing in recent years. Data and fecal samples from colorectal cancer patients were collected at the Amizour Public Hospital's oncology department (Bejaia, Algeria). Microbiological and cohort study were conducted at the Biological Engineering of Cancers laboratory at the Faculty of Medicine of the University of Bejaia. All the data showed that patients aged between 50 and 70 years were the most affected by colorectal cancer, while the age categories of [30-40] and [40-50] were the least affected. Males were more likely to be at risk of contracting colorectal cancer than females. The most common types of colorectal cancer among the studied population were sigmoid cancer, rectal cancer, transverse colon cancer, and ascending colon cancer. The hereditary factor was found to be more dominant than other risk factors. Bacterial identification revealed the presence of certain pathogenic and opportunistic bacterial genera, such as E. coli, K. pneumoniae, Shigella sp, and Streptococcus group D. These results led us to conclude that dysbiosis of the intestinal microbiome is strongly present in colorectal cancer patients at the EPH of Amizour. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microbiome" title="microbiome">microbiome</a>, <a href="https://publications.waset.org/abstracts/search?q=colorectal%20cancer" title=" colorectal cancer"> colorectal cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factors" title=" risk factors"> risk factors</a>, <a href="https://publications.waset.org/abstracts/search?q=bacterial%20identification" title=" bacterial identification"> bacterial identification</a> </p> <a href="https://publications.waset.org/abstracts/164659/dysbiosis-of-the-intestinal-microbiome-in-colorectal-cancer-patients-at-hospital-of-amizour-bejaia-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164659.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">36</span> Opaque Mineralogy of the Late Precambrian Ophiolites from Bou Azzer Area, Anti-atlas, Morrocco</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yaser%20Maher%20Abdelaziz%20Hawa">Yaser Maher Abdelaziz Hawa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Basic-ultrabasic rocks of Bou Azzer ophiolite complex in the Anti-atlas , Morrocco enclose some oxide and sulfide minerals as dissiminated traces.

The permeable breakwaters are partially protection and have been suggested to overcome the environmental disadvantages of fully protection breakwaters. For regular waves a semi-analytical model is based on an eigenfunction expansion method and utilizes a boundary condition at the surface of each wall are developed to detect the energy dissipation through the slots. Extensive laboratory tests are carried out to validate the semi-analytic models. The structure of the physical model contains two walls and it consists of impermeable upper and lower part, where the draft is based a decimal multiple of the total depth. The middle part is permeable with a porosity of 50%. The second barrier is located at a distant of 0.5, 1, 1.5 and 2 times of the water depth from the first one. A comparison of the theoretical results with previous studies and experimental measurements of the present study show a good agreement and that, the semi-analytical model is able to adequately reproduce most the important features of the experiment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=permeable%20breakwater" title="permeable breakwater">permeable breakwater</a>, <a href="https://publications.waset.org/abstracts/search?q=double%20vertical%20slotted%20walls" title=" double vertical slotted walls"> double vertical slotted walls</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-analytical%20model" title=" semi-analytical model"> semi-analytical model</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20coefficient" title=" transmission coefficient"> transmission coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=reflection%20coefficient" title=" reflection coefficient"> reflection coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20dissipation%20coefficient" title=" energy dissipation coefficient"> energy dissipation coefficient</a> </p> <a href="https://publications.waset.org/abstracts/12805/experimental-and-semi-analytical-investigation-of-wave-interaction-with-double-vertical-slotted-walls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12805.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">385</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">34</span> An Antifungal Peptide from Actinobacteria (Streptomyces Sp.

So, the aim of the study was to identify nurse's role in early detection of breast cancer through mammography and genetic screening and its impact on patient's outcome. In order to achieve this aim, 400 women above 40 years, asymptomatic were recruited for mammography and genetic screening. In addition, 50 nurses and 6 technologists were involved in the study. A descriptive analytical design was used. Five tools were utilized: sociodemographic, mammographic examination and risk factors, women's before, during and after mammography, items relaying to technologists, and items related to nurses were also obtained. The study finding revealed that 3% of women detected for malignancy and 7.25% for fibroadenoma. Statistically, significant differences were found between mammography results and age, family history, genetic screening, exposure to smoke, and using contraceptive pills. Nurses have insufficient knowledge about screening tests. Based on these findings the present study recommended involvement of nurses in breast care which is very important to in force population about screening practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mammography" title="mammography">mammography</a>, <a href="https://publications.waset.org/abstracts/search?q=early%20detection" title=" early detection"> early detection</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20screening" title=" genetic screening"> genetic screening</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title=" breast cancer"> breast cancer</a> </p> <a href="https://publications.waset.org/abstracts/22557/nurses-role-in-early-detection-of-breast-cancer-through-mammography-and-genetic-screening-and-its-impact-on-patients-outcome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22557.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">562</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">32</span> Effect of Humic Substance on Ex-Vitro Propagation of Saffron (Crocus Sativus L.)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelghani%20Tahiri">Abdelghani Tahiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Youssef%20Karra"> Youssef Karra</a>, <a href="https://publications.waset.org/abstracts/search?q=Naima%20Ait%20Aabd"> Naima Ait Aabd</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelaziz%20Mimouni"> Abdelaziz Mimouni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Saffron (Crocus sativus L.), the most expensive spice in the world derived from the stigmas, is an autumn-flowering and sterile triploid (2n=3x=24) geophyte species that belong to the Iridaceae family. This plant species is mainly propagated vegetatively through the formation of daughter corms from the mother one. Low multiplication rates of daughter corms under natural conditions, along with fungal contamination, significantly reduce the productivity and quality of saffron corms. The development of efficient and sustainable strategies for rapid and large-scale production of selected cultivars of saffron will be desired. For this, the main objective of this work is to improve the vegetative propagation of saffron under ex-vitro conditions. Preliminary results of the influence of increasing doses of humic substances (HS) on the growth and multiplication of corms under greenhouse conditions are evaluated. The obtained data shows that the effect of HS depends on the concentration used and the mode of application. Indeed, the application through irrigation has increased the number of shoots and corms, but it has reduced other parameters. On the other hand, the temporary treatment has improved all observed parameters except for the number of shoots and corms. Results obtained in this work suggest that it is possible to improve the propagation of saffron corms under greenhouse conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=saffron" title="saffron">saffron</a>, <a href="https://publications.waset.org/abstracts/search?q=Crocus%20sativus%20L." title=" Crocus sativus L."> Crocus sativus L.</a>, <a href="https://publications.waset.org/abstracts/search?q=corm" title=" corm"> corm</a>, <a href="https://publications.waset.org/abstracts/search?q=humic%20substances" title=" humic substances"> humic substances</a> </p> <a href="https://publications.waset.org/abstracts/132968/effect-of-humic-substance-on-ex-vitro-propagation-of-saffron-crocus-sativus-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132968.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">211</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">31</span> Differentiation between Different Rangeland Sites Using Principal Component Analysis in Semi-Arid Areas of Sudan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nancy%20Ibrahim%20Abdalla">Nancy Ibrahim Abdalla</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelaziz%20Karamalla%20Gaiballa"> Abdelaziz Karamalla Gaiballa </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rangelands in semi-arid areas provide a good source for feeding huge numbers of animals and serving environmental, economic and social importance; therefore, these areas are considered economically very important for the pastoral sector in Sudan. This paper investigates the means of differentiating between different rangelands sites according to soil types using principal component analysis to assist in monitoring and assessment purposes. Three rangeland sites were identified in the study area as flat sandy sites, sand dune site, and hard clay site. Principal component analysis (PCA) was used to reduce the number of factors needed to distinguish between rangeland sites and produce a new set of data including the most useful spectral information to run satellite image processing. It was performed using selected types of data (two vegetation indices, topographic data and vegetation surface reflectance within the three bands of MODIS data). Analysis with PCA indicated that there is a relatively high correspondence between vegetation and soil of the total variance in the data set. The results showed that the use of the principal component analysis (PCA) with the selected variables showed a high difference, reflected in the variance and eigenvalues and it can be used for differentiation between different range sites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=principal%20component%20analysis" title="principal component analysis">principal component analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=PCA" title=" PCA"> PCA</a>, <a href="https://publications.waset.org/abstracts/search?q=rangeland%20sites" title=" rangeland sites"> rangeland sites</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-arid%20areas" title=" semi-arid areas"> semi-arid areas</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20types" title=" soil types"> soil types</a> </p> <a href="https://publications.waset.org/abstracts/99240/differentiation-between-different-rangeland-sites-using-principal-component-analysis-in-semi-arid-areas-of-sudan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99240.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">186</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">30</span> Effect of Heat Stress on the Physiology of the Cork Oak</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Zekri">J.

The combination of these factors resulted in damage alarmed, therefore forest ecosystems weakened trees that can affect their ability to support other abiotic and biotic stresses, For this we tested its tolerance to thermal variations and cold weather conditions by estimating some stress markers (quantification of proteins, RNA, soluble sugars) that are quantified to evaluate the cold tolerance of seedlings. Sowing of cork oak (Quercus suber L.) is grown in controlled conditions at 25° C ± 2° C in long days 16h. These seedlings are transferred at low temperatures between 5° C and -6° C for a period of 3 hours. Biochemical analyzes were performed in the various organs of the cork oak seedlings. Cool temperatures induced a significant accumulation of proline in different organs of seedlings and the optimum concentrations were observed in the roots with very high concentrations (4 times larger than those of the control). The accumulation of soluble sugars is significantly in stems and roots at 0° C. Protein concentrations are very high in leaves of both growth and high waves in rod at -4° C to -2° C. Tolerance cork oak seems to be at the thermal limit of -2°C. The concentration of these metabolites in the various organs showed the ability oak cork hardening during the winter. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20change" title=" thermal change"> thermal change</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-aride" title=" semi-aride"> semi-aride</a>, <a href="https://publications.waset.org/abstracts/search?q=biochemical%20markers" title=" biochemical markers"> biochemical markers</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20stress" title=" heat stress"> heat stress</a> </p> <a href="https://publications.waset.org/abstracts/30096/effect-of-heat-stress-on-the-physiology-of-the-cork-oak" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30096.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">249</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">29</span> Aqueous Two Phase Extraction of Jonesia denitrificans Xylanase 6 in PEG 1000/Phosphate System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nawel%20Boucherba">Nawel Boucherba</a>, <a href="https://publications.waset.org/abstracts/search?q=Azzedine%20Bettache"> Azzedine Bettache</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelaziz%20Messis"> Abdelaziz Messis</a>, <a href="https://publications.waset.org/abstracts/search?q=Francis%20Duchiron"> Francis Duchiron</a>, <a href="https://publications.waset.org/abstracts/search?q=Said%20Benallaoua"> Said Benallaoua</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The impetus for research in the field of bioseparation has been sparked by the difficulty and complexity in the downstream processing of biological products. Indeed, 50% to 90% of the production cost for a typical biological product resides in the purification strategy. There is a need for efficient and economical large scale bioseparation techniques which will achieve high purity and high recovery while maintaining the biological activity of the molecule. One such purification technique which meets these criteria involves the partitioning of biomolecules between two immiscible phases in an aqueous system (ATPS). The Production of xylanases is carried out in 500ml of a liquid medium based on birchwood xylan. In each ATPS, PEG 1000 is added to a mixture consisting of dipotassium phosphate, sodium chloride and the culture medium inoculated with the strain Jonesia denitrificans, the mixture was adjusted to different pH. The concentration of PEG 1000 was varied: 8 to 16 % and the NaCl percentages are also varied from 2 to 4% while maintaining the other parameters constant. The results showed that the best ATPS for purification of xylanases is composed of PEG 1000 at 8.33%, 13.14 % of K2HPO4, 1.62% NaCl at pH 7. We obtained a yield of 96.62 %, a partition coefficient of 86.66 and a purification factor of 2.9. The zymogram showed that the activity is mainly detected in the top phase. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jonesia%20denitrificans%20BN13" title="Jonesia denitrificans BN13">Jonesia denitrificans BN13</a>, <a href="https://publications.waset.org/abstracts/search?q=xylanase" title=" xylanase"> xylanase</a>, <a href="https://publications.waset.org/abstracts/search?q=aqueous%20two%20phases%20system" title=" aqueous two phases system"> aqueous two phases system</a>, <a href="https://publications.waset.org/abstracts/search?q=zymogram" title=" zymogram "> zymogram </a> </p> <a href="https://publications.waset.org/abstracts/27076/aqueous-two-phase-extraction-of-jonesia-denitrificans-xylanase-6-in-peg-1000phosphate-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27076.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">399</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">28</span> 128-Multidetector CT for Assessment of Optimal Depth of Electrode Array Insertion in Cochlear Implant Operations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amina%20Sultan">Amina Sultan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Ghonim"> Mohamed Ghonim</a>, <a href="https://publications.waset.org/abstracts/search?q=Eman%20Oweida"> Eman Oweida</a>, <a href="https://publications.waset.org/abstracts/search?q=Aya%20%20Abdelaziz"> Aya Abdelaziz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: To assess the diagnostic reliability of multi-detector CT in pre and post-operative evaluation of cochlear implant candidates. Material and Methods: The study includes 40 patients (18 males and 22 females); mean age 5.6 years. They were classified into two groups: Group A (20 patients): cochlear implant device was Nucleus-22 and Group B (20 patients): the device was MED-EL. Cochlear length (CL) and cochlear height (CH) were measured pre-operatively by 128-multidetector CT. Electrode length (EL) and insertion depth angle (α) were measured post-operatively by MDCT. Results: For Group A mean CL was 9.1 mm ± 0.4 SD; mean CH was 4.1 ± 0.3 SD; mean EL was 18 ± 2.7 SD; mean α angle was 299.05 ± 37 SD. Significant statistical correlation (P < 0.05) was found between preoperative CL and post-operative EL (r²=0.6); as well as EL and α angle (r²=0.7). Group B's mean CL was 9.1 mm ± 0.3 SD; mean CH was 4.1 ± 0.4 SD; mean EL was 27 ± 2.1 SD; mean α angle was 287.6 ± 41.7 SD. Significant statistical correlation was found between CL and EL (r²= 0.6) and α angle (r²=0.5). Also, a strong correlation was found between EL and α angle (r²=0.8). Significant statistical difference was detected between the two devices as regards to the electrode length. Conclusion: Multidetector CT is a reliable tool for preoperative planning and post-operative evaluation of the outcomes of cochlear implant operations. Cochlear length is a valuable prognostic parameter for prediction of the depth of electrode array insertion which can influence criteria of device selection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=angle%20of%20insertion%20%28%CE%B1%20angle%29" title="angle of insertion (α angle)">angle of insertion (α angle)</a>, <a href="https://publications.waset.org/abstracts/search?q=cochlear%20implant%20%28CI%29" title=" cochlear implant (CI)"> cochlear implant (CI)</a>, <a href="https://publications.waset.org/abstracts/search?q=cochlear%20length%20%28CL%29" title=" cochlear length (CL)"> cochlear length (CL)</a>, <a href="https://publications.waset.org/abstracts/search?q=Multidetector%20Computed%20Tomography%20%28MDCT%29" title=" Multidetector Computed Tomography (MDCT)"> Multidetector Computed Tomography (MDCT)</a> </p> <a href="https://publications.waset.org/abstracts/78950/128-multidetector-ct-for-assessment-of-optimal-depth-of-electrode-array-insertion-in-cochlear-implant-operations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78950.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">193</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">27</span> Optimize Study and Optical Characterization of Bilayer Structures from Silicon Nitride</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Beddiaf%20Abdelaziz">Beddiaf Abdelaziz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The optical characteristics of thin films of silicon oxynitride SiOₓNy prepared by the Low-Pressure Chemical Vapor Deposition (LPCVD) technique have been studied. The films are elaborated from the SiH₂Cl₂, N₂O and NH₃ gaseous mixtures. The flows of SiH₂Cl₂ and (N₂O+NH₃) are 200 sccm and 160 sccm respectively. The deposited films have been characterized by ellipsometry, to model our silicon oxynitride SiOₓNy films. We have suggested two theoretical models (Maxwell Garnett and Bruggeman effective medium approximation (BEMA)). These models have been applied on silicon oxynitride considering the material as a heterogeneous medium formed by silicon oxide and silicon nitride. The model's validation was justified by the confrontation of theoretical spectra and those measured by ellipsometry. This result permits us to obtain the optical refractive coefficient of these films and their thickness. Ellipsometry analysis of the optical properties of the SiOₓNy films shows that the SiO₂ fraction decreases when the gaseous ratio NH₃/N₂O increases. Whereas the increase of this ratio leads to an increase of the silicon nitride Si3N4 fraction. The study also shows that the increasing gaseous ratio leads to a strong incorporation of nitrogen atoms in films. Also, the increasing of the SiOₓNy refractive coefficient until the SiO₂ value shows that this insulating material has good dielectric quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ellipsometry" title="ellipsometry">ellipsometry</a>, <a href="https://publications.waset.org/abstracts/search?q=silicon%20oxynitrde" title=" silicon oxynitrde"> silicon oxynitrde</a>, <a href="https://publications.waset.org/abstracts/search?q=model" title=" model"> model</a>, <a href="https://publications.waset.org/abstracts/search?q=refractive%20coefficient" title=" refractive coefficient"> refractive coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=effective%20medium" title=" effective medium"> effective medium</a> </p> <a href="https://publications.waset.org/abstracts/192533/optimize-study-and-optical-characterization-of-bilayer-structures-from-silicon-nitride" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192533.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">18</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">26</span> Finite Element Modeling of Friction Stir Welding of Dissimilar Alloys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fadi%20Al-Badour">Fadi Al-Badour</a>, <a href="https://publications.waset.org/abstracts/search?q=Nesar%20Merah"> Nesar Merah</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelrahman%20Shuaib"> Abdelrahman Shuaib</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelaziz%20Bazoune"> Abdelaziz Bazoune</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the current work, a Coupled Eulerian Lagrangian (CEL) model is developed to simulate the friction stir welding (FSW) process of dissimilar Aluminum alloys (Al 6061-T6 with Al 5083-O). The model predicts volumetric defects, material flow, developed temperatures, and stresses in addition to tool reaction loads. Simulation of welding phase is performed by employing a control volume approach, whereas the welding speed is defined as inflow and outflow over Eulerian domain boundaries. Only material softening due to inelastic heat generation is considered and material behavior is assumed to obey Johnson-Cook’s Model. The model was validated using published experimentally measured temperatures, at similar welding conditions, and by qualitative comparison of dissimilar weld microstructure. The FE results showed that most of developed temperatures were below melting and that the bulk of the deformed material in solid state. The temperature gradient on AL6061-T6 side was found to be less than that of Al 5083-O. Changing the position Al 6061-T6 from retreating (Ret.) side to advancing (Adv.) side led to a decrease in maximum process temperature and strain rate. This could be due to the higher resistance of Al 6061-T6 to flow as compared to Al 5083-O. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=friction%20stir%20welding" title="friction stir welding">friction stir welding</a>, <a href="https://publications.waset.org/abstracts/search?q=dissimilar%20metals" title=" dissimilar metals"> dissimilar metals</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20modeling" title=" finite element modeling"> finite element modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=coupled%20Eulerian%0D%0ALagrangian%20Analysis" title=" coupled Eulerian Lagrangian Analysis"> coupled Eulerian Lagrangian Analysis</a> </p> <a href="https://publications.waset.org/abstracts/2021/finite-element-modeling-of-friction-stir-welding-of-dissimilar-alloys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2021.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">331</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">25</span> Anxiety and Change in Eating Habits and Health Behaviors among Adult Women during COVID-19 Pandemic Lockdown in Alexandria, Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Heba%20Ahmed%20Abdelaziz">Heba Ahmed Abdelaziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Doaa%20Tawfik%20Mohamed%20Ibrahim"> Doaa Tawfik Mohamed Ibrahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: COVID-19 pandemic is the major health problem facing the world recently, causing variable effects on mental health and eating behavior.

Conclusion: the current study concluded that stressful situations like lockdown due to COVID-19 pandemic is associated with anxiety (severe, moderate, mild then minimal, respectively) along with changes in eating habits, physical activity, sleeping pattern and smoking. <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=lockdown" title=" lockdown"> lockdown</a>, <a href="https://publications.waset.org/abstracts/search?q=females" title=" females"> females</a>, <a href="https://publications.waset.org/abstracts/search?q=anxiety" title=" anxiety"> anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=eating" title=" eating"> eating</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a>, <a href="https://publications.waset.org/abstracts/search?q=lifestyle" title=" lifestyle"> lifestyle</a> </p> <a href="https://publications.waset.org/abstracts/143756/anxiety-and-change-in-eating-habits-and-health-behaviors-among-adult-women-during-covid-19-pandemic-lockdown-in-alexandria-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143756.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">189</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Mineralogical and Geochemical Constraints on the Origin and Environment of Numidian Siliceous Sedimentary Rocks of the Extreme Northwest Tunisia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ben%20Yahia%20Nouha">Ben Yahia Nouha</a>, <a href="https://publications.waset.org/abstracts/search?q=Harris%20Chris"> Harris Chris</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebei%20Abdelaziz"> Sebei Abdelaziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Boussen%20Slim"> Boussen Slim</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaabani%20Fredj"> Chaabani Fredj</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present work has set itself the objective of studying non-detritic siliceous rocks of the extreme northwest Tunisia. It aims to examine the origin and their sedimentary depositional environment based on mineralogical and geochemical characteristics. The different sections were located in the area of Babouch and the area of Tabarka. The collected samples were subjected to mineralogical and geochemical characterization using different analytical methods: X-ray diffraction (XRD), geochemical analysis (ICP- AES), isotopic geochemistry (δ18O), to assess their suitability for industrial use. X-ray powder diffraction of the pure siliceous rock indicates quartz as the major mineral, with the total lack of amorphous silica. Trace impurities, such as carbonate and clay minerals, are concealed in the analytical results. The petrographic examination revealed allowed us to deduce that this rock was deriving from tests of siliceous organisms (the radiolarians). The chemical composition shows that SiO2, Al2O3, and Fe2O3 represent the most abundant oxides. The other oxides are present in negligible quantities. Geochemical data support a biogenic and non-hydrothermal origin of babouchite silica. Oxygen isotopic has shown that babouchites were formed in an environment with a high temperature ranging from 56 °C to 73 °C. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biogenic%20silica" title="biogenic silica">biogenic silica</a>, <a href="https://publications.waset.org/abstracts/search?q=babouchite%20formation" title=" babouchite formation"> babouchite formation</a>, <a href="https://publications.waset.org/abstracts/search?q=XRD" title=" XRD"> XRD</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20analysis" title=" chemical analysis"> chemical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=oxygen%20isotopic" title=" oxygen isotopic"> oxygen isotopic</a>, <a href="https://publications.waset.org/abstracts/search?q=northwest%20tunisia" title=" northwest tunisia"> northwest tunisia</a> </p> <a href="https://publications.waset.org/abstracts/141975/mineralogical-and-geochemical-constraints-on-the-origin-and-environment-of-numidian-siliceous-sedimentary-rocks-of-the-extreme-northwest-tunisia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141975.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">145</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">23</span> Knowledge, Attitude, and Practice Among Diabetic Patients About Diabetic Foot Disease in Khartoum State Primary Health Care Centers, November 2022</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abrar%20Noorain">Abrar Noorain</a>, <a href="https://publications.waset.org/abstracts/search?q=Zeinab%20Amara"> Zeinab Amara</a>, <a href="https://publications.waset.org/abstracts/search?q=Sulaf%20Abdelaziz"> Sulaf Abdelaziz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Diabetic foot disease imposes a financial burden on diabetic patients and healthcare services. 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">22</span> New Environmental Culture in Algeria: Eco Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Tireche">S.

Among the avenues to be explored, one of the most promising is certainly one that focuses on product design. Indeed, where better than during the design phase, can reduce the source of future impacts on the environment? What choices or those of design, they influence more on the environmental characteristics of products? The most currently recognized at the international level is the analysis of the life cycle (LCA) and Life Cycle Assessment, subject to International Standardization (ISO 14040-14043). LCA provides scientific and objective assessment of potential impacts of the product or service, considering its entire life cycle. This approach makes it possible to minimize impacts to the source in pollution prevention. It is widely preferable to curative approach, currently majority in the industrial crops, led mostly by a report of pollution. The "product" is to reduce the environmental impacts of a given product, taking into account all or part of its life cycle. Currently, there are emerging tools, known as eco-design. They are intended to establish an environmental profile of the product to improve its environmental performance. They require a quantity sufficient information on the product for each phase of its life cycle: raw material extraction, manufacturing, distribution, usage, end of life (recycling or incineration or deposit) and all stages of transport. The assessment results indicate the sensitive points of the product studied, points on which the developer must act. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eco%20design" title="eco design">eco design</a>, <a href="https://publications.waset.org/abstracts/search?q=impact" title=" impact"> impact</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20analysis%20%28LCA%29" title=" life cycle analysis (LCA)"> life cycle analysis (LCA)</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/22490/new-environmental-culture-in-algeria-eco-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22490.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">427</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">21</span> Factors Associated with Mammography Screening Behaviors: A Cross-Sectional Descriptive Study of Egyptian Women </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salwa%20Hagag%20Abdelaziz">Salwa Hagag Abdelaziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Naglaa%20Fathy%20Youssef"> Naglaa Fathy Youssef</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Abdellatif%20Hassan"> Nadia Abdellatif Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Rasha%20Wesam%20Abdelrahman"> Rasha Wesam Abdelrahman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Breast cancer is considered as a substantial health concern and practicing mammography screening [MS] is important in minimizing its related morbidity. So it is essential to have a better understanding of breast cancer screening behaviors of women and factors that influence utilization of them. The aim of this study is to identify the factors that are linked to MS behaviors among the Egyptian women. A cross-sectional descriptive design was carried out to provide a snapshot of the factors that are linked to MS behaviors. A convenience sample of 311 women was utilized and all eligible participants admitted to the Women Imaging Unit who are 40 years of age or above, coming for mammography assessment, not pregnant or breast feeding and who accepted to participate in the study were included. A structured questionnaire was developed by the researchers and contains three parts; Socio-demographic data; Motivating factors associated with MS; and association between MS and model of behavior change. The analyzed data indicated that most of the participated women (66.6 %) belonged to the age group of 40-49.A high proportion of participants (58.1%) of group having previous MS influenced by their neighbors to practice MS, whereas 32.7 % in group not having previous MS were influenced by family members which indicated significant differences (P <0.05). Doctors and media are shown to be the least influence of others to practice MS. Women with intention to have a future mammogram had higher OR (1.404) for practicing MS compared with women with no intention. Further studies are needed to examine the relation between Trans-theoretical Model [TTM] and practicing MS. <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=mammography" title=" mammography"> mammography</a>, <a href="https://publications.waset.org/abstracts/search?q=screening%20behaviors" title=" screening behaviors"> screening behaviors</a>, <a href="https://publications.waset.org/abstracts/search?q=morbidity" title=" morbidity"> morbidity</a> </p> <a href="https://publications.waset.org/abstracts/28433/factors-associated-with-mammography-screening-behaviors-a-cross-sectional-descriptive-study-of-egyptian-women" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28433.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">442</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">20</span> The Impact of Maternal Micronutrient Levels on Risk of Offspring Neural Tube Defects in Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eman%20M.%20El-Sayed">Eman M.

Poor nutrition was essential factor for central nervous system deformation. Mothers gave NTD offspring had abnormal serum levels of micronutrients. The present research was designed to study the effect of maternal micronutrient levels and oxidative stress on the incidence of NTD in offspring. The study included forty mothers; twenty of them of 30.9+7.28 years had conceived fetuses with NTD were considered as cases; and twenty mothers of 28.2 + 7.82 years with healthy neonates. We determined serum vitamin B12 and folic acid by using radioimmunoassays. Also, serum zinc was assessed using atomic absorption spectrophotometry. While serum copper and iron were measured colorimetrically and serum ceruloplasmin was analyzed by radialimmunodiffusion. Cases showed significantly lower levels of folic acid, vitamin B12 and zinc (P< 0.0005, 0.01, 0.01 respectively) than that of the control. Concentrations of copper, ceruloplasmin, and iron were markedly increased in cases as compared to controls (P < 0.01, 0.01, and 0.05 respectively). In conclusion, the current study clearly indicated the etiology of NTD cannot be explained with one strict etiologic mechanism, on the contrary, an interaction among maternal nutritional factors and oxidative stress would explain these anomalies. Vitamin B12, folic acid, and zinc supplementations should be considered for further decrease in the occurrence of NTD. Preventing excess iron during pregnancy favors better pregnancy outcomes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ceruloplasmin" title="ceruloplasmin">ceruloplasmin</a>, <a href="https://publications.waset.org/abstracts/search?q=copper" title=" copper"> copper</a>, <a href="https://publications.waset.org/abstracts/search?q=folic%20acid" title=" folic acid"> folic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=iron" title=" iron"> iron</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20tube%20defects" title=" neural tube defects"> neural tube defects</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title=" oxidative stress"> oxidative stress</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20b12" title=" vitamin b12"> vitamin b12</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc" title=" zinc"> zinc</a> </p> <a href="https://publications.waset.org/abstracts/77879/the-impact-of-maternal-micronutrient-levels-on-risk-of-offspring-neural-tube-defects-in-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77879.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">221</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Health Hazards Among Health Care Workers and Associated Factors in Public Hospitals, Sana'a-Yemen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Makkia%20Ahmad%20Ali%20Al-Falahi">Makkia Ahmad Ali Al-Falahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdullah%20Abdelaziz%20Muharram"> Abdullah Abdelaziz Muharram</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Healthcare workers (HCWs) in Yemen are exposed to a myriad of occupational health hazards, including biological, physical, ergonomic, chemical and psychosocial hazards. HCWs operate in an environment that is considered to be one of the most hazardous occupational settings. Objective: To assess the prevalence of occupational health hazards among healthcare workers and associated risk factors in public hospitals in Sana'a City, Yemen. Method: Descriptive cross-sectional design was utilized; out of 5443 totals of HCWs 396 were selected by multistage sampling technique was carried out in the public hospitals in Sana'a city, Yemen. Results: More the half (60.6%) of HCWs aged between 20-30 years, (50.8%) were males, (56.3%) were married, and (45.5%) had a diploma qualification, while (65.2%) of HCWs had less than 6 years of experience. The result showed that the highest prevalence of occupational hazards was (99%), (ergonomic hazards (93.4%), biological hazards (87.6%), psychosocial (86.65%), physical hazards (83.3%), and chemical hazards (73.5%). There were no statistically significant differences between demographic characteristics and the prevalence of occupational hazards (p >0.05). Conclusion and recommendations: The study showed the highest prevalence of occupational hazards; regarding the prevalence of biological hazards exposure to sharp-related injury, the most prevalent physical hazards were slip/trip/and fall. Ergonomic hazards had back or neck pain during work. Chemical hazards were allergic to medical gloves powder. On psychosocial hazards was suffered from verbal and physical harassment.

The purpose of this study is to describe the main reasons for demand for care in primary health care, through a survey of the Ariana Governorate PHC and to identify their evolutionary trend compared to last 30 years, reported by studies of the same type. Materials and methods: This is a cross-sectional descriptive study which concerns the study of consultants in the first line of the governorate of Ariana and their use of care recorded during 2 days in the same week during the month of May 2016, in each of these PHC. The same data collection sheet was used in all CSBs. The coding of the information was done according to the International Classification of Primary Care (ICPC). The data was entered and analyzed by the EPI Info 7 software. Results: Our study found that the most common ICPC chapters are respiratory (42%) and digestive (13.2%). In 1996 were the respiratory (43.5%) and circulatory (7.8%). In 2000, we found also the respiratory (39,6%) and circulatory (10,9%). In 2002, respiratory (43%) and digestive (10.1%) motives were the most frequent. According to the ICPC, the pathologies in our study were acute angina (19%), acute bronchitis and bronchiolitis (8%). In 1996, it was tonsillitis ( 21.6%) and acute bronchitis (7.2%). For Ben Abdelaziz in 2000, tonsillitis (14.5%) follow by acute bronchitis (8.3%). In 2002, acute angina (15.7%), acute bronchitis and bronchiolitis (11.2%) were the most common.

In Morocco, 61.3% of women of reproductive age (WRA) are overweight or obese, including 30.4% who were obese, while 34.4% were anaemic, and 49.7% have iron deficiency anaemia. Objective: This study aims to determine the prevalence of DBM at the individual level among Moroccan WRA, defined by the coexistence of iron deficiency anaemia and overweight/obesity. Methods: a cross-sectional national survey was conducted among a representative sample of 2090 Moroccan WRA. Data collected included socio-economic parameters, anthropometric measurements, and blood samples. Haemoglobin levels were measured photometrically using Hemocue, while ferritin and CRP were assessed through immunoturbudimetry. Results: The prevalence of overweight/obesity, iron deficiency, anaemia and iron deficiency anaemia among WRA in Morocco were 60.2%, 30.6%, 34.4% and 50.0% respectively. The coexistence of overweight/obesity with anaemia and iron deficiency was observed in 19.2% and 16.3% of women, respectively. Among overweight/obese women, 32.5% were anaemic, 28.4% were iron deficient, and 47.6% had iron deficiency anaemia. the prevalence of DBM was higher in urban areas compared to rural settings. Conclusion: The coexistence of undernutrition and overnutrition among WRA highlights the urgent need for integrated public health interventions addressing both anaemia and obesity simultaneously. Tailored strategies should consider the specific socio-economic and geographical contexts to effectively combat this dual burden. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=the%20double%20burden%20of%20malnutrition" title="the double burden of malnutrition">the double burden of malnutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20deficiency%20anaemia" title=" iron deficiency anaemia"> iron deficiency anaemia</a>, <a href="https://publications.waset.org/abstracts/search?q=overweight" title=" overweight"> overweight</a>, <a href="https://publications.waset.org/abstracts/search?q=obesity" title=" obesity"> obesity</a> </p> <a href="https://publications.waset.org/abstracts/191962/prevalence-of-the-double-burden-of-malnutrition-in-women-of-childbearing-age-in-morocco-coexistence-of-iron-deficiency-anemia-and-overweight" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191962.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">33</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Hydro-Climatological, Geological, Hydrogeological and Geochemical Study of the Coastal Aquifer System of Chiba Watershed (Cape Bon Peninsula)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khawla%20Askri">Khawla Askri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Haythem%20Msaddek"> Mohamed Haythem Msaddek</a>, <a href="https://publications.waset.org/abstracts/search?q=AbdelAziz%20Sebei"> AbdelAziz Sebei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Climate change combined with the increase in anthropogenic activities will affect coastal groundwater systems around the world and, more particularly, the Cap Bon region in the North East of Tunisia. This study aims to study the impact of climate change and human stress on the salinization and quantification of groundwater in the Wadi Chiba watershed. In this regard, a hydro-climatological study and a hydrogeological study were carried out based on the characterization of the aquifer system of the eastern coast at the level of the watershed of Wadi Chiba in order to seek to identify, first of all, the degradation of the state of the aquifer on the quantitative level by the study of the piezometric and its evolution over time. Secondly, we sought to identify the degradation of the state of the aquifer qualitatively by using the geochemical method, in particular the major elements, to assess the mineralization of the aquifer water and understand its hydrogeochemical functioning. The study of the Na + / Cl- and Ca2 + / Mg2 + chemical relationships confirmed the presence of a marine intrusion downstream of the Wadi Chiba watershed northeast of Cap-Bon accompanied by a piezometric depression. For this purpose, we proceeded to: 1) Mapping of both piezometric data and salinity. 2) The interpretation of the mapping results. 3)Identification of the origin of the localized deterioration in the quality of the aquifer water. Finally, the analysis of the results showed that the scarcity of water is already forcing human actions in the Chiba watershed due to the irrigation of agricultural lands and the overexploitation of the water table in the study area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20activities" title=" human activities"> human activities</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20table" title=" water table"> water table</a>, <a href="https://publications.waset.org/abstracts/search?q=Wadi%20Chiba%20watershed" title=" Wadi Chiba watershed"> Wadi Chiba watershed</a>, <a href="https://publications.waset.org/abstracts/search?q=piezometric%20depression" title=" piezometric depression"> piezometric depression</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20intrusion" title=" marine intrusion"> marine intrusion</a> </p> <a href="https://publications.waset.org/abstracts/163279/hydro-climatological-geological-hydrogeological-and-geochemical-study-of-the-coastal-aquifer-system-of-chiba-watershed-cape-bon-peninsula" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163279.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">92</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Potential Risks of Using Disconnected Composite Foundation Systems in Active Seismic Zones</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20ElMasry">Mohamed ElMasry</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Ragheb"> Ahmad Ragheb</a>, <a href="https://publications.waset.org/abstracts/search?q=Tareq%20AbdelAziz"> Tareq AbdelAziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Ghazy"> Mohamed Ghazy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Choosing the suitable infrastructure system is becoming more challenging with the increase in demand for heavier structures contemporarily. This is the case where piled raft foundations have been widely used around the world to support heavy structures without extensive settlement. In the latter system, piles are rigidly connected to the raft, and most of the load goes to the soil layer on which the piles are bearing. In spite of that, when soil profiles contain thicker soft clay layers near the surface, or at relatively shallow depths, it is unfavorable to use the rigid piled raft foundation system. Consequently, the disconnected piled raft system was introduced as an alternative approach for the rigidly connected system. In this system, piles are disconnected from the raft using a cushion of soil, mostly of a granular interlayer. The cushion is used to redistribute the stresses among the piles and the subsoil. Piles are also used to stiffen the subsoil, and by this way reduce the settlement without being rigidly connected to the raft. However, the seismic loading effect on such disconnected foundation systems remains a problem, since the soil profiles may include thick clay layers which raise risks of amplification of the dynamic earthquake loads. In this paper, the effects of seismic behavior on the connected and disconnected piled raft systems are studied through a numerical model using Midas GTS NX Software. The study concerns the soil-structure interaction and the expected behavior of the systems. Advantages and disadvantages of each foundation approach are studied, and a comparison between the results are presented to show the effects of using disconnected piled raft systems in highly seismic zones. This was done by showing the excitation amplification in each of the foundation systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soil-structure%20interaction" title="soil-structure interaction">soil-structure interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=disconnected%20piled-raft" title=" disconnected piled-raft"> disconnected piled-raft</a>, <a href="https://publications.waset.org/abstracts/search?q=risks" title=" risks"> risks</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20zones" title=" seismic zones"> seismic zones</a> </p> <a href="https://publications.waset.org/abstracts/77623/potential-risks-of-using-disconnected-composite-foundation-systems-in-active-seismic-zones" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77623.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">14</span> Assessing the Double Burden of Malnutrition in Moroccan Women: A Focus on Iron Deficiency and Weight Disorders</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fall%20Abdourahmane">Fall Abdourahmane</a>, <a href="https://publications.waset.org/abstracts/search?q=Lazrak%20Meryem"> Lazrak Meryem</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Hsaini%20Houda"> El Hsaini Houda</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Ammari%20Laila"> El Ammari Laila</a>, <a href="https://publications.waset.org/abstracts/search?q=Gamih%20Hasnae"> Gamih Hasnae</a>, <a href="https://publications.waset.org/abstracts/search?q=Yahyane%20Abdelhakim"> Yahyane Abdelhakim</a>, <a href="https://publications.waset.org/abstracts/search?q=Benjouad%20Abdelaziz"> Benjouad Abdelaziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Aguenaou%20Hassan"> Aguenaou Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Kari%20Khalid"> El Kari Khalid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The double burden of malnutrition (DBM), defined by the concurrent occurrence of undernutrition and overnutrition, represents a critical public health issue, particularly in low- and middle-income countries. In Morocco, 61.3% of women of reproductive age (WRA) are classified as overweight or obese, with 30.4% meeting the criteria for obesity. Furthermore, 34.4% of WRA are affected by anaemia, and 49.7% present with iron deficiency anaemia. Objective: The objective of this study is to assess the individual-level prevalence of the double burden of malnutrition (DBM) among Moroccan WRA, focusing on the simultaneous presence of iron deficiency anaemia and overweight/obesity. Methods: A national cross-sectional survey was carried out on a representative sample of 2090 Moroccan WRA. The data collected encompassed blood samples, anthropometric measurements and socio-economic factors. Haemoglobin levels were assessed using a Hemocue device, while ferritin and CRP levels were determined through immunoturbidimetric analysis. Results: The prevalence of overweight/obesity among WRA in Morocco was 60.2%, iron deficiency affected 30.6%, anaemia was found in 34.4%, and 50.0% had iron deficiency anaemia. The coexistence of overweight/obesity with anaemia was observed in 19.2% and with iron deficiency in 16.3%. Among overweight/obese women, 32.5% were anaemic, 28.4% had iron deficiency, and 47.6% had iron deficiency anaemia. The prevalence of DBM was higher in urban areas compared to rural settings. Conclusion: The DBM among women of WRA showed an emergent reality of the interconnection and the coexistence at individual level of the undernutrition and the overnutrition. Therefore, effective and dual actions that could simultaneously address the double dimension of the DBM have to be implemented for the policy solutions to be successful. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=the%20double%20burden%20of%20malnutrition" title="the double burden of malnutrition">the double burden of malnutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20deficiency%20anemia" title=" iron deficiency anemia"> iron deficiency anemia</a>, <a href="https://publications.waset.org/abstracts/search?q=overweight" title=" overweight"> overweight</a>, <a href="https://publications.waset.org/abstracts/search?q=obesity" title=" obesity"> obesity</a> </p> <a href="https://publications.waset.org/abstracts/192091/assessing-the-double-burden-of-malnutrition-in-moroccan-women-a-focus-on-iron-deficiency-and-weight-disorders" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192091.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">20</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Comparative Study Between Two Different Techniques for Postoperative Analgesia in Cesarean Section Delivery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nermeen%20Elbeltagy">Nermeen Elbeltagy</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Hassan"> Sara Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Tamer%20Hosny"> Tamer Hosny</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Abdelaziz"> Mostafa Abdelaziz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Adequate postoperative analgesia after caesarean section (CS) is crucial as it impacts the distinct surgical recovery needs of the parturient. Over recent years, there has been increased interest in regional nerve block techniques with promising results on efficacy. These techniques reduce the need for additional analgesia, thereby lowering the incidence of drug-related side effects. As postoperative pain after cesarean is mainly due to abdominal incision, the transverses abdomenis plane ( TAP ) block is a relatively new abdominal nerve block with excellent efficacy after different abdominal surgeries, including cesarean section. Objective: The main objective is to compare ultrasound-guided TAP block provided by the anesthesiologist with TAP provided by the surgeon through a caesarean incision regarding the duration of postoperative analgesia, intensity of analgesia, timing of mobilization, and easiness of the procedure. Method: Ninety pregnant females at term who were scheduled for delivery by elective cesarean section were randomly distributed into two groups. The first group (45) received spinal anesthesia and postoperative ultrasound guided TAP block using 20ml on each side of 0.25% bupivacaine which was provided by the anesthesiologist. The second group (45) received spinal anesthesia plus a TAP block using 20ml on each side of 0.25% bupivacaine, which was provided by the surgeon through the cesarean incision. Visual Analogue Scale (VAS) was used for the comparison between the two groups. Results: VAS score after four hours was higher among the TAP block group provided by the surgeon through the surgical incision than the postoperative analgesic profile using ultrasound-guided TAP block provided by the anesthesiologist (P=0.011). On the contrary, there was no statistical difference in the patient’s dose of analgesia after four hours of the TAP block (P=0.228). Conclusion: TAP block provided through the surgical incision is safe and enhances early patient’s mobilization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=TAP%20block" title="TAP block">TAP block</a>, <a href="https://publications.waset.org/abstracts/search?q=CS" title=" CS"> CS</a>, <a href="https://publications.waset.org/abstracts/search?q=VAS" title=" VAS"> VAS</a>, <a href="https://publications.waset.org/abstracts/search?q=analgesia" title=" analgesia"> analgesia</a> </p> <a href="https://publications.waset.org/abstracts/184456/comparative-study-between-two-different-techniques-for-postoperative-analgesia-in-cesarean-section-delivery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184456.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">49</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Sustainable Community Education: Strategies for Long-Term Impact</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kariman%20Abdelaziz%20Ahmed%20Ali%20Hamzawy">Kariman Abdelaziz Ahmed Ali Hamzawy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Amidst the growing global challenges facing communities, from climate change to educational gaps, sustainable community education has emerged as a vital tool for ensuring comprehensive and enduring development. This research aims to explore effective strategies for sustainable community education that can lead to long-term impacts on local communities. The study begins by defining the concept of sustainable education within a community context and reviews the current literature on the topic. It then presents case studies from various communities around the world where sustainable educational strategies have been successfully implemented. These case studies illustrate how sustainable education can enhance community engagement, build local capacities, and improve quality of life in sustainable ways. The findings from these studies are analyzed to identify the key factors contributing to the success of sustainable educational programs. These factors include partnerships between different sectors (governmental, private, and community), the innovative use of technology, and the adaptation of educational curricula to meet the unique needs of the community. The research also offers practical recommendations on designing and implementing sustainable educational programs, emphasizing the integration of formal and informal education, promoting lifelong learning, and developing local resources. It addresses potential challenges and ways to overcome them to ensure the long-term sustainability of these programs. In conclusion, the research provides a future vision of the role of sustainable education in building resilient and prosperous communities and highlights the importance of investing in education as a key driver of sustainable development. This study contributes to the ongoing discussion on achieving lasting impact through sustainable community education and offers a practical framework for stakeholders to adopt and implement these
