evaluation of the antioxidant activity of the Peganum harmala (P. harmala) seeds extracts. The antioxidant activity was evaluated by applying two methods, the method of ß-carotene bleaching and DPPH (2, 2-Diphenyl-1-Picryl-Hydrazyl). Using Folin-Ciocalteu assay, these results revealed that the concentration of polyphenols in EthOH E. (122.28 ± 2.24 µg GAE/mg extract) is the highest. The antiradical activity of the P. harmala seeds extracts on DPPH was found to be dose dependent with polyphenols concentration. The E. EthOH extract showed the highest antioxidant activity (IC = 252.10 ± 11.18 μg /ml). The test of β-carotene bleaching indicates that the E. EthOH of P. harmala showed the highest percentage of the antioxidant activity (49.88 %). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title="antioxidant activity">antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=Peganum%20harmala" title=" Peganum harmala"> Peganum harmala</a>, <a href="https://publications.waset.org/abstracts/search?q=polyphenols" title=" polyphenols"> polyphenols</a>, <a href="https://publications.waset.org/abstracts/search?q=flavonoids" title=" flavonoids "> flavonoids </a> </p> <a href="https://publications.waset.org/abstracts/32852/polyphenols-content-and-antioxidant-activity-of-extracts-from-peganum-harmala-seeds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32852.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">506</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">374</span> High-Resolution Spatiotemporal Retrievals of Aerosol Optical Depth from Geostationary Satellite Using Sara Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Bilal">Muhammad Bilal</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhongfeng%20Qiu"> Zhongfeng Qiu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aerosols, suspended particles in the atmosphere, play an important role in the earth energy budget, climate change, degradation of atmospheric visibility, urban air quality, and human health. To fully understand aerosol effects, retrieval of aerosol optical properties such as aerosol optical depth (AOD) at high spatiotemporal resolution is required. Therefore, in the present study, hourly AOD observations at 500 m resolution were retrieved from the geostationary ocean color imager (GOCI) using the simplified aerosol retrieval algorithm (SARA) over the urban area of Beijing for the year 2016. The SARA requires top-of-the-atmosphere (TOA) reflectance, solar and sensor geometry information and surface reflectance observations to retrieve an accurate AOD. For validation of the GOCI retrieved AOD, AOD measurements were obtained from the aerosol robotic network (AERONET) version 3 level 2.0 (cloud-screened and quality assured) data. The errors and uncertainties were reported using the root mean square error (RMSE), relative percent mean error (RPME), and the expected error (EE = ± (0.05 + 0.15AOD). Results showed that the high spatiotemporal GOCI AOD observations were well correlated with the AERONET AOD measurements with a correlation coefficient (R) of 0.92, RMSE of 0.07, and RPME of 5%, and 90% of the observations were within the EE. The results suggested that the SARA is robust and has the ability to retrieve high-resolution spatiotemporal AOD observations over the urban area using the geostationary satellite. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AEORNET" title="AEORNET">AEORNET</a>, <a href="https://publications.waset.org/abstracts/search?q=AOD" title=" AOD"> AOD</a>, <a href="https://publications.waset.org/abstracts/search?q=SARA" title=" SARA"> SARA</a>, <a href="https://publications.waset.org/abstracts/search?q=GOCI" title=" GOCI"> GOCI</a>, <a href="https://publications.waset.org/abstracts/search?q=Beijing" title=" Beijing"> Beijing</a> </p> <a href="https://publications.waset.org/abstracts/101729/high-resolution-spatiotemporal-retrievals-of-aerosol-optical-depth-from-geostationary-satellite-using-sara-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101729.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">171</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">373</span> In vivo Alterations in Ruminal Parameters by Megasphaera Elsdenii Inoculation on Subacute Ruminal Acidosis (SARA)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20S.%20Alatas">M.

Umucalilar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> SARA is a common and serious metabolic disorder in early lactation in dairy cattle and in finishing beef cattle, caused by diets with high inclusion of cereal grain. This experiment was performed to determine the efficacy of Megasphaera elsdenii, a major lactate-utilizing bacterium in prevention/treatment of SARA in vivo. In vivo experimentation, it was used eight ruminally cannulated rams and it was applied the rapid adaptation with the mixture of grain based on wheat (%80 wheat, %20 barley) and barley (%80 barley, %20 wheat). During the systematic adaptation, it was followed the probability of SARA formation by being measured the rumen pH with two hours intervals after and before feeding. After being evaluated the data, it was determined the ruminal pH ranged from 5,2-5,6 on the condition of feeding with 60 percentage of grain mixture based on barley and wheat, that assured the definite form of subacute acidosis. In four days SARA period, M. elsdenii (1010 cfu ml-1) was inoculated during the first two days. During the SARA period, it was observed the decrease of feed intake with M. elsdenii inoculation. Inoculation of M. elsdenii was caused to differentiation of rumen pH (P < 0,0001), while it was found the pH level approximately 5,55 in animals applied the inoculation, it was 5,63 pH in other animals. It was observed that total VFA with the bacterium inoculation tended to change in terms of grain feed (P < 0,07). It increased with the effect of total VFA inoculation in barley based diet, but it was more stabilized in wheat based diet. Bacterium inoculation increased the ratio of propionic acid (18,33%-21,38%) but it caused to decrease the butyric acid, and acetic/propionic acid. During the rapid adaptation, the concentration of lactic acid in the rumen liquid increased depending upon grain level (P<0,0001). On the other hand bacterium inoculation did not have an effect on concentration of lactic acid. M. elsdenii inoculation did not affect ruminal ammonia concentration. In the group that did not apply inoculation, the level of ruminal ammonia concentration was higher than the others applied inoculation. M. elsdenii inoculation did not changed protozoa count in barley-based diet whereas it decreased in wheat-based diet. In the period of SARA, it was observed that the level of blood glucose, lactate and hematocrit increased greatly after inoculation (P < 0,0001). When it is generally evaluated, it is seen that M. elsdenii inoculation has not a positive impact on rumen parameters. Therefore, to reveal the full impact of the inoculation with different strains, feedstuffs and animal groups, further research is required. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=In%20vivo" title="In vivo">In vivo</a>, <a href="https://publications.waset.org/abstracts/search?q=Subactute%20ruminal%20acidosis" title=" Subactute ruminal acidosis"> Subactute ruminal acidosis</a>, <a href="https://publications.waset.org/abstracts/search?q=Megasphaera%20elsdenii" title=" Megasphaera elsdenii"> Megasphaera elsdenii</a>, <a href="https://publications.waset.org/abstracts/search?q=Rumen%20fermentation" title=" Rumen fermentation"> Rumen fermentation</a> </p> <a href="https://publications.waset.org/abstracts/26011/in-vivo-alterations-in-ruminal-parameters-by-megasphaera-elsdenii-inoculation-on-subacute-ruminal-acidosis-sara" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26011.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">645</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">372</span> Lifting Wavelet Transform and Singular Values Decomposition for Secure Image Watermarking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siraa%20Ben%20Ftima">Siraa Ben Ftima</a>, <a href="https://publications.waset.org/abstracts/search?q=Mourad%20Talbi"> Mourad Talbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Tahar%20Ezzedine"> Tahar Ezzedine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we present a technique of secure watermarking of grayscale and color images.

In this study, methanol, toluene, and xylene were investigated as potential hydrocarbon solvents for solvent-aided hydrocarbon recovery of Agbabu bitumen. Solubility, Viscosity, and Saturate, Aromatic, Resin and Asphaltene (SARA) Analysis tests were carried out to determine the solubility of the bitumen in the solvents, the viscosity, and the SARA fraction of the natural bitumen and bitumen-solvent mixtures. Agbabu bitumen was found to have a high content of saturates and aromatics. Viscosity decreases as pressure increases, while solubility reduces as temperature increases. The experimental diffusivity of the sample decreases with temperature and increases with pressure, indicating that the presence of additional solvent molecules in the oil phase facilitates diffusion. Agbabu bitumen was found to be most soluble in toluene, and its viscosity was reduced most in it. Xylene exhibited a similar effect as toluene on the sample, though lesser but better than methanol. Methanol reduced the saturated content and significantly raised the asphaltene content, keeping the mixture viscosity high, a condition that, in turn, favors its colloidal stability. The colloidal instability index (CII) values, which account for the asphaltene stability of the mixture, show that the bitumen-methanol system with a CII of 0.874 will have mild asphaltene deposit issues while others are unstable. This approach of combining multiple tests with the CII can accurately predict the behavior of Agbabu bitumen in solvents and enhance the decision on the choice of bitumen recovery technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asphaltene" title="asphaltene">asphaltene</a>, <a href="https://publications.waset.org/abstracts/search?q=bitumen" title=" bitumen"> bitumen</a>, <a href="https://publications.waset.org/abstracts/search?q=diffusivity" title=" diffusivity"> diffusivity</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrocarbon%20solvent" title=" hydrocarbon solvent"> hydrocarbon solvent</a>, <a href="https://publications.waset.org/abstracts/search?q=SARA" title=" SARA"> SARA</a> </p> <a href="https://publications.waset.org/abstracts/187476/solvent-aided-dilution-approach-for-heavy-hydrocarbon-liquid-evaluation-in-the-eastern-dahomey-basin-southwestern-nigeria-case-study-of-agbabu-bitumen-in-ondo-state" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187476.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">36</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">370</span> Mutagenic in vitro Activity and Genotoxic Effect of Zygophyllum Cornutun Methanolic Extract </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Awatif%20Boumaza">Awatif Boumaza</a>, <a href="https://publications.waset.org/abstracts/search?q=Abderraouf%20Hilali"> Abderraouf Hilali</a>, <a href="https://publications.waset.org/abstracts/search?q=Hayat%20Talbi"> Hayat Talbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Houda%20Sbayou"> Houda Sbayou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The methanolic extract of Zygophyllum cornutun coss, an Algerian medicinal plant, was screened to the presence of mutagenic activity and genotoxic effect using the Ames test (Salmonella/microsome) and the micronucleus assay respectively.

The physical properties of both crudes such as density, viscosity, pour point and sulphur content were measured according to (ASTM) method. To examine the stability of both crudes and their blends, the oil compatibility model using microscopic, colloidal instability index (CII) using SARA analysis and asphaltene stabilization test using Turbiscan tests were conducted in the Libyan Petroleum Institute laboratories. Compatibility tests were carried out with both crude oils, the insolubility number (IN), and the solubility blending number (SBN), for both crude oils and their blends were calculated. The criteria for compatibility of any blend is that the volume average solubility blending number (SBN) is greater than the insolubility number (IN) of any component in the blend, the results indicated that both crudes were compatible. To support the results of compatibility tests the SARA analysis was done for the fractional determination of (saturates, aromatics, resins and asphaltenes) content. From this result, the colloidal Instability index (CII) and resin to asphaltenes ratio (R/A) were calculated for crudes and their blends. The results show that crude oil (B) which has higher (R/A) and lower (CII) is more stable than crude oil (A) and as the ratio of crude (B) increases in the blend the (CII) and (R/A) were improved, and the blends becomes more stable. Asphaltene stabilization test was also conducted for the crudes and their blends using Turbiscan MA200 according to the standard test method ASTM D7061-04, the Turbiscan shows that the crude (B) is more stable than crude (A) which shows a fair tendency. The (CII) and (R/A) were compared with the solubility number (SBN) for each crude and the blends along with Turbiscan results. The solubility blending number (SBN) of the crudes and their blends show that the crudes are compatible, also by comparing (R/A) and (SBN) values of the blends, it can be seen that they are complements of each other. All the experimental results show that the blends of both crudes are more stability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asphaltene" title="asphaltene">asphaltene</a>, <a href="https://publications.waset.org/abstracts/search?q=crude%20oil" title=" crude oil"> crude oil</a>, <a href="https://publications.waset.org/abstracts/search?q=compatibility" title=" compatibility"> compatibility</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20blends" title=" oil blends"> oil blends</a>, <a href="https://publications.waset.org/abstracts/search?q=resin" title=" resin"> resin</a>, <a href="https://publications.waset.org/abstracts/search?q=SARA" title=" SARA"> SARA</a> </p> <a href="https://publications.waset.org/abstracts/68752/blending-effects-on-crude-oil-stability-an-experimental-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68752.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">511</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">368</span> Main Chaos-Based Image Encryption Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibtissem%20Talbi">Ibtissem Talbi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During the last decade, a variety of chaos-based cryptosystems have been investigated. Most of them are based on the structure of Fridrich, which is based on the traditional confusion-diffusion architecture proposed by Shannon. Compared with traditional cryptosystems (DES, 3DES, AES, etc.), the chaos-based cryptosystems are more flexible, more modular and easier to be implemented, which make them suitable for large scale-data encyption, such as images and videos. The heart of any chaos-based cryptosystem is the chaotic generator and so, a part of the efficiency (robustness, speed) of the system depends greatly on it. In this talk, we give an overview of the state of the art of chaos-based block ciphers and we describe some of our schemes already proposed. Also we will focus on the essential characteristics of the digital chaotic generator, The needed performance of a chaos-based block cipher in terms of security level and speed of calculus depends on the considered application. There is a compromise between the security and the speed of the calculation. The security of these block block ciphers will be analyzed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chaos-based%20cryptosystems" title="chaos-based cryptosystems">chaos-based cryptosystems</a>, <a href="https://publications.waset.org/abstracts/search?q=chaotic%20generator" title=" chaotic generator"> chaotic generator</a>, <a href="https://publications.waset.org/abstracts/search?q=security%20analysis" title=" security analysis"> security analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=structure%20of%20Fridrich" title=" structure of Fridrich"> structure of Fridrich</a> </p> <a href="https://publications.waset.org/abstracts/13064/main-chaos-based-image-encryption-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13064.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">684</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">367</span> Forecasting Cancers Cases in Algeria Using Double Exponential Smoothing Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Messis%20A.">Messis A.</a>, <a href="https://publications.waset.org/abstracts/search?q=Adjebli%20A."> Adjebli A.</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayeche%20R."> Ayeche R.</a>, <a href="https://publications.waset.org/abstracts/search?q=Talbi%20M."> Talbi M.</a>, <a href="https://publications.waset.org/abstracts/search?q=Tighilet%20K."> Tighilet K.</a>, <a href="https://publications.waset.org/abstracts/search?q=Louardiane%20M."> Louardiane M.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cancers are the second cause of death worldwide. Prevalence and incidence of cancers is getting increased by aging and population growth. This study aims to predict and modeling the evolution of breast, Colorectal, Lung, Bladder and Prostate cancers over the period of 2014-2019. In this study, data were analyzed using time series analysis with double exponential smoothing method to forecast the future pattern. To describe and fit the appropriate models, Minitab statistical software version 17 was used. Between 2014 and 2019, the overall trend in the raw number of new cancer cases registered has been increasing over time; the change in observations over time has been increasing. Our forecast model is validated since we have good prediction for the period 2020 and data not available for 2021 and 2022. Time series analysis showed that the double exponential smoothing is an efficient tool to model the future data on the raw number of new cancer cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer" title="cancer">cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20series" title=" time series"> time series</a>, <a href="https://publications.waset.org/abstracts/search?q=prediction" title=" prediction"> prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=double%20exponential%20smoothing" title=" double exponential smoothing"> double exponential smoothing</a> </p> <a href="https://publications.waset.org/abstracts/164142/forecasting-cancers-cases-in-algeria-using-double-exponential-smoothing-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164142.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">88</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">366</span> Prevalence and Characteristics of Consumption of Nutraceuticals: The Case Study of Undergraduate Students of Medellin- Colombia, 2013</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gloria%20In%C3%A9s%20Mart%C3%ADnez%20Dom%C3%ADnguez">Gloria Inés Martínez Domínguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Mart%C3%ADnez%20S%C3%A1nchez"> Lina María Martínez Sánchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20de%20los%20%C3%81ngeles%20Rodr%C3%ADguez%20G%C3%A1zquez"> María de los Ángeles Rodríguez Gázquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Guillermo%20Jim%C3%A9nez%20Jim%C3%A9nez"> Juan Guillermo Jiménez Jiménez</a>, <a href="https://publications.waset.org/abstracts/search?q=Johan%20Sebasti%C3%A1n%20Lopera%20Valle"> Johan Sebastián Lopera Valle</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Vargas%20Grisales"> Natalia Vargas Grisales</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Rojas%20Jim%C3%A9nez"> Sara Rojas Jiménez</a>, <a href="https://publications.waset.org/abstracts/search?q=Alejandra%20Uribe%20Ocampo"> Alejandra Uribe Ocampo</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Correa%20P%C3%A9rez"> Sara Correa Pérez</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Perilla%20Hern%C3%A1ndez"> Natalia Perilla Hernández</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Sebasti%C3%A1n%20Mar%C3%ADn%20C%C3%A1rdenas"> Juan Sebastián Marín Cárdenas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The relationship between diet and chronic or degenerative diseases has led to the development of functional foods such as nutraceuticals.

It was a simple random sampling with the Statcalc EpiInfo software vr 6.04. It was designed an instrument for collection of demographic data and consumption of nutraceuticals. Statistical analysis used the SPSS program. Results: 427 students, average age 20.8 years (SD 3.1), 56.1% were women. The life prevalence of nutraceuticals consumption was 66.3% and the annual 51.8%. The main reasons for consumption were as food complement 32.8% and prevent diseases 20.1%. Conclusion: The high prevalence of nutraceuticals observed is comparable to that reported in the literature, which suggests an increasing trend in the habit of consumption of dietary supplement which have a preventive or protective effect on health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dietary%20supplements" title="dietary supplements">dietary supplements</a>, <a href="https://publications.waset.org/abstracts/search?q=food" title=" food"> food</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20food" title=" functional food"> functional food</a>, <a href="https://publications.waset.org/abstracts/search?q=Colombia" title=" Colombia"> Colombia</a> </p> <a href="https://publications.waset.org/abstracts/1597/prevalence-and-characteristics-of-consumption-of-nutraceuticals-the-case-study-of-undergraduate-students-of-medellin-colombia-2013" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1597.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">576</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">365</span> Optimizing Exposure Parameters in Digital Mammography: A Study in Morocco </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Talbi%20Mohammed">Talbi Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Oustous%20Aziz"> Oustous Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Ben%20Messaoud%20Mounir"> Ben Messaoud Mounir</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebihi%20Rajaa"> Sebihi Rajaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Khalis%20Mohammed"> Khalis Mohammed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Breast cancer is the leading cause of death for women around the world. Screening mammography is the reference examination, due to its sensitivity for detecting small lesions and micro-calcifications. Therefore, it is essential to ensure quality mammographic examinations with the most optimal dose. These conditions depend on the choice of exposure parameters. Clinically, practices must be evaluated in order to determine the most appropriate exposure parameters. Material and Methods: We performed our measurements on a mobile mammography unit (PLANMED Sofie-classic.) in Morocco. A solid dosimeter (AGMS Radcal) and a MTM 100 phantom allow to quantify the delivered dose and the image quality. For image quality assessment, scores are defined by the rate of visible inserts (MTM 100 phantom), obtained and compared for each acquisition. Results: The results show that the parameters of the mammography unit on which we have made our measurements can be improved in order to offer a better compromise between image quality and breast dose. The last one can be reduced up from 13.27% to 22.16%, while preserving comparable image quality. <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=Breast%20Dose" title=" Breast Dose"> Breast Dose</a>, <a href="https://publications.waset.org/abstracts/search?q=Image%20Quality" title=" Image Quality"> Image Quality</a>, <a href="https://publications.waset.org/abstracts/search?q=Phantom" title=" Phantom"> Phantom</a> </p> <a href="https://publications.waset.org/abstracts/116596/optimizing-exposure-parameters-in-digital-mammography-a-study-in-morocco" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116596.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">172</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">364</span> Group Boundaries against and Due to Identity Threat </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Siegler">Anna Siegler</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Bigazzi"> Sara Bigazzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Serdult"> Sara Serdult</a>, <a href="https://publications.waset.org/abstracts/search?q=Ildiko%20Bokretas"> Ildiko Bokretas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Social identity emerging from group membership defines the representational processes of our social reality. Based on our theoretical assumption the subjective perception of identity threat leads to an instable identity structure. The need to re-establish the positive identity will lead us to strengthen group boundaries. Prejudice in our perspective offer psychological security those who thinking in exclusive barriers, and we suggest that those who identify highly with their ingroup/national identity and less with superordinate identities take distance from others and this is related to their perception of threat. In our study we used a newly developed questionnaire, the Multiple Threat and Prejudice Questionnaire (MTPQ) which measure identity threat at different dimensions of identification (national, existential, gender, religious) and the distancing of different outgroups, over and above we worked with Social Dominance Orientation (SDO) and Identification with All Humanity Scale (IWAH). We conduct one data collection (N=1482) in a Hungarian sample to examine the connection between national threat and distance-taking, and this survey includes the investigation (N=218) of identification with different group categories. Our findings confirmed that those who feel themselves threatened in their national identity aspects are less likely to identify themselves with superordinate groups and this correlation is much stronger when they think about the nation as a bio-cultural unit, while if nation defined as a social-economy entity this connection is less powerful and has just the opposite direction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=group%20boundaries" title="group boundaries">group boundaries</a>, <a href="https://publications.waset.org/abstracts/search?q=identity%20threat" title=" identity threat"> identity threat</a>, <a href="https://publications.waset.org/abstracts/search?q=prejudice" title=" prejudice"> prejudice</a>, <a href="https://publications.waset.org/abstracts/search?q=superordinate%20groups" title=" superordinate groups"> superordinate groups</a> </p> <a href="https://publications.waset.org/abstracts/93684/group-boundaries-against-and-due-to-identity-threat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93684.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">410</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">363</span> Study of the Effect of Extraction Solvent on the Content of Total Phenolic, Total Flavonoids and the Antioxidant Activity of an Endemic Medicinal Plant Growing in Morocco</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aghoutane%20Basma">Aghoutane Basma</a>, <a href="https://publications.waset.org/abstracts/search?q=Naama%20Amal"> Naama Amal</a>, <a href="https://publications.waset.org/abstracts/search?q=Talbi%20Hayat"> Talbi Hayat</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Manfalouti%20Hanae"> El Manfalouti Hanae</a>, <a href="https://publications.waset.org/abstracts/search?q=Kartah%20Badreddine"> Kartah Badreddine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aromatic and medicinal plants are used by man for different needs, including food and medicinal needs for their biological properties attributed mainly to phenolic compounds and for their antioxidant capacity.

This activity was also confirmed by three methods (2,2-diphenyl-1-picrylhydrazyl (DPPH), antioxidant reducing power of iron (FRAP), and total antioxidant capacity (CAT)).

This compression system is a modified version of the compression system using a MDCT (Modified Discrete Cosine Transform) filter banks of 32 filters each and the psychoacoustic model. This modification consists in replacing the banks of the MDCT filter banks by the bionic wavelet coefficients which are obtained from the application of the BWT to the speech signal to be compressed. These two methods are evaluated and compared with each other by computing bits before and bits after compression. They are tested on different speech signals and the obtained simulation results show that the proposed technique outperforms the second technique and this in term of compressed file size. In term of SNR, PSNR and NRMSE, the outputs speech signals of the proposed compression system are with acceptable quality. In term of PESQ and speech signal intelligibility, the proposed speech compression technique permits to obtain reconstructed speech signals with good quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=speech%20compression" title="speech compression">speech compression</a>, <a href="https://publications.waset.org/abstracts/search?q=bionic%20wavelet%20transform" title=" bionic wavelet transform"> bionic wavelet transform</a>, <a href="https://publications.waset.org/abstracts/search?q=filterbanks" title=" filterbanks"> filterbanks</a>, <a href="https://publications.waset.org/abstracts/search?q=psychoacoustic%20model" title=" psychoacoustic model"> psychoacoustic model</a> </p> <a href="https://publications.waset.org/abstracts/1921/application-of-the-bionic-wavelet-transform-and-psycho-acoustic-model-for-speech-compression" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1921.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">384</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">361</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">360</span> Conducting Quality Planning, Assurance and Control According to GMP (Good Manufacturing Practices) Standards and Benchmarking Data for Kuwait Food Industries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alaa%20Alateeqi">Alaa Alateeqi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Aldhulaiee"> Sara Aldhulaiee</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Alibraheem"> Sara Alibraheem</a>, <a href="https://publications.waset.org/abstracts/search?q=Noura%20Alsaleh"> Noura Alsaleh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For the past few decades or so, Kuwait's local food industry has grown remarkably due to increase in demand for processed or semi processed food products in the market. It is important that the ever increasing food manufacturing/processing units maintain the required quality standards as per regional and to some extent international quality requirements. It has been realized that all Kuwait food manufacturing units should understand and follow the international standard practices, and moreover a set of guidelines must be set for quality assurance such that any new business in this area is aware of the minimum requirements. The current study has been undertaken to identify the gaps in Kuwait food industries in following the Good Manufacturing Practices (GMP) in terms of quality planning, control and quality assurance. GMP refers to Good Manufacturing Practices, which are a set of rules, laws or regulations that certify producing products within quality standards and ensuring that it is safe, pure and effective. The present study therefore reports about a ‘case study’ in a reputed food manufacturing unit in Kuwait; starting from assessment of the current practices followed by diagnosis, report of the diagnosis and road map and corrective measures for GMP implementation in the unit. The case study has also been able to identify the best practices and establish a benchmarking data for other companies to follow, through measuring the selected company's quality, policies, products and strategies and compare it with the established benchmarking data. A set of questionnaires and assessment mechanism has been established for companies to identify their ‘benchmarking score’ in relation to the number of non-conformities and conformities with the GMP standard requirements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=good%20manufacturing%20practices" title="good manufacturing practices">good manufacturing practices</a>, <a href="https://publications.waset.org/abstracts/search?q=GMP" title=" GMP"> GMP</a>, <a href="https://publications.waset.org/abstracts/search?q=benchmarking" title=" benchmarking"> benchmarking</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuwait%20Food%20Industries" title=" Kuwait Food Industries"> Kuwait Food Industries</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20quality" title=" food quality"> food quality</a> </p> <a href="https://publications.waset.org/abstracts/9184/conducting-quality-planning-assurance-and-control-according-to-gmp-good-manufacturing-practices-standards-and-benchmarking-data-for-kuwait-food-industries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9184.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">467</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">359</span> Burnout Syndrome: A Study of Financial Professionals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sara%20Santos">Sara Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Jo%C3%A3o%20Santos"> Maria João Santos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Thisarticleanalyzesthethemeofwork-family conflict and professional stress among financial workers and their relationships with burnout syndrome.

Photoelectrochemical reduction of carbon dioxide to value-added products and fuels is a promising and current method. The objective of our study is to develop Cu₂S-based photoélectrodes, in which Cu₂S is used as a CO₂ photoelectrocatalyst deposited on nanostructured silicon substrates. Cu₂S thin layers were deposited using the chemical bath deposition (CBD) technique. Silicon nanowires and nanopyramids were obtained by alkaline etching. SEM and UV-visible spectroscopy was used to analyse the morphology and optical characteristics. By using a potentiostat station, we characterized the photoelectrochemical properties. We performed cyclic voltammetry in the presence and without CO₂ purging as well as linear voltammetry (LSV) in the dark and under white light irradiation. We perform chronoamperometry to study the stability of our photocathodes. The quality of the nanowires and nanopyramids was visible in the SEM images, and after Cu₂S deposition, we could see how the deposition was distributed over the textured surfaces. The inclusion of the Cu₂S layer applied on textured substrates significantly reduces the reflectance (R%). The catalytic performance towards CO₂ conversion of Cu₂S/Si-based photocathodes revealed that the texturing of the silicon surface with nanowires and pyramids has a better photoelectrochemical behavior than those without surface modifications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20conversion" title="CO₂ conversion">CO₂ conversion</a>, <a href="https://publications.waset.org/abstracts/search?q=Cu%E2%82%82S%20photocathode" title=" Cu₂S photocathode"> Cu₂S photocathode</a>, <a href="https://publications.waset.org/abstracts/search?q=silicone%20nanostructured" title=" silicone nanostructured"> silicone nanostructured</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemistry" title=" electrochemistry"> electrochemistry</a> </p> <a href="https://publications.waset.org/abstracts/170801/impact-of-silicon-surface-modification-on-the-catalytic-performance-towards-co2-conversion-of-cu2ssi-based-photocathodes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170801.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">78</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">355</span> Waiting Time Reduction in a Government Hospital Emergency Department: A Case Study on AlAdan Hospital, Kuwait</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bashayer%20AlRobayaan">Bashayer AlRobayaan</a>, <a href="https://publications.waset.org/abstracts/search?q=Munira%20Saad"> Munira Saad</a>, <a href="https://publications.waset.org/abstracts/search?q=Alaa%20AlBawab"> Alaa AlBawab</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20AlHamad"> Fatma AlHamad</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20AlAwadhi"> Sara AlAwadhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sherif%20Fahmy"> Sherif Fahmy </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper addresses the problem of long waiting times in government hospitals emergency departments (ED).

However, the performance of the anode material in LIBs is crucial for enhancing the battery's overall efficiency. This research focuses on developing a new anode material by modifying silicon nanostructures, specifically porous silicon nanowires (PSiNWs) and porous silicon nanoparticles (NPSiP), with silver nanoparticles (Ag) to improve the performance of LIBs. The aim of this research is to investigate the potential application of PSiNWs/Ag and NPSiP/Ag as anodes in LIBs and evaluate their performance in terms of specific capacity and Coulombic efficiency. The research methodology involves the preparation of PSiNWs and NPSiP using metal-assisted chemical etching and electrochemical etching techniques, respectively. The Ag nanoparticles are introduced onto the nanostructures through electrodissolution of the porous film and ultrasonic treatment. Galvanostatic charge/discharge measurements are conducted between 1 and 0.01 V to evaluate the specific capacity and Coulombic efficiency of both PSiNWs/Ag and NPSiP/Ag electrodes. The specific capacity of the PSiNWs/Ag electrode is approximately 1800 mA h g-1, with a Coulombic efficiency of 98.8% at the first charge/discharge cycle. On the other hand, the NPSiP/Ag electrode exhibits a specific capacity of 2600 mAh g-1. Both electrodes show a slight increase in capacity retention after 80 cycles, attributed to the high porosity and surface area of the nanostructures and the stabilization of the solid electrolyte interphase (SEI). This research highlights the potential of using modified silicon nanostructures as anodes for LIBs, which can pave the way for the development of more efficient lithium-ion batteries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=porous%20silicon%20nanowires" title="porous silicon nanowires">porous silicon nanowires</a>, <a href="https://publications.waset.org/abstracts/search?q=silicon%20nanoparticles" title=" silicon nanoparticles"> silicon nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20batteries" title=" lithium-ion batteries"> lithium-ion batteries</a>, <a href="https://publications.waset.org/abstracts/search?q=galvanostatic%20charge%2Fdischarge" title=" galvanostatic charge/discharge"> galvanostatic charge/discharge</a> </p> <a href="https://publications.waset.org/abstracts/171753/an-anode-based-on-modified-silicon-nanostructured-for-lithium-ion-battery-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171753.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">63</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">351</span> Detecting Black Hole Attacks in Body Sensor Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sara%20Alshehri">Sara Alshehri</a>, <a href="https://publications.waset.org/abstracts/search?q=Bayan%20Alenzi"> Bayan Alenzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Atheer%20Alshehri"> Atheer Alshehri</a>, <a href="https://publications.waset.org/abstracts/search?q=Samia%20Chelloug"> Samia Chelloug</a>, <a href="https://publications.waset.org/abstracts/search?q=Zainab%20Almry"> Zainab Almry</a>, <a href="https://publications.waset.org/abstracts/search?q=Hussah%20Albugmai"> Hussah Albugmai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper concerns body area networks sensor that collect signals around a human body.

Key aspects of the federal species at risk program include the development of recovery documents (recovery strategies, action plans, and management plans) outlining threats, objectives, and broad strategies or measures for conservation or recovery of the species; the identification and protection of critical habitat for threatened and endangered species; and working with groups and organizations to implement on-the-ground recovery actions. Environment Canada’s progress on the development of recovery documents and on the identification and protection of critical habitat in Ontario will be presented, along with successes and challenges associated with on-the ground implementation of recovery actions. In Ontario, Environment Canada is currently involved in several recovery and monitoring programs for at-risk bird species such as the Loggerhead Shrike, Piping Plover, Golden-winged Warbler and Cerulean Warbler and has provided funding for a wide variety of recovery actions targeting priority species at risk and geographic areas each year through stewardship programs including the Habitat Stewardship Program, Aboriginal Fund for Species at Risk, and the Interdepartmental Recovery Fund. Key research needs relevant to the recovery of species at risk have been identified, and include: surveys and monitoring of population sizes and threats, population viability analyses, and addressing knowledge gaps identified for individual species (e.g., species biology and habitat needs). The engagement of all levels of government, the local and international conservation communities, and the scientific research community plays an important role in the conservation and recovery of species at risk in Ontario– through surveying and monitoring, filling knowledge gaps, conducting public outreach, and restoring, protecting, or managing habitat – and will be critical to the continued success of the federal species at risk program. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conservation%20biology" title="conservation biology">conservation biology</a>, <a href="https://publications.waset.org/abstracts/search?q=habitat%20protection" title=" habitat protection"> habitat protection</a>, <a href="https://publications.waset.org/abstracts/search?q=species%20at%20risk" title=" species at risk"> species at risk</a>, <a href="https://publications.waset.org/abstracts/search?q=wildlife%20recovery" title=" wildlife recovery"> wildlife recovery</a> </p> <a href="https://publications.waset.org/abstracts/22960/towards-conservation-and-recovery-of-species-at-risk-in-ontario-progress-on-recovery-planning-and-implementation-and-an-overview-of-key-research-needs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22960.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">452</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">349</span> Snapchat’s Scanning Feature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reham%20Banwair">Reham Banwair</a>, <a href="https://publications.waset.org/abstracts/search?q=Lana%20Alshehri"> Lana Alshehri</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Hadrawi"> Sara Hadrawi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this project is to identify user satisfaction with the AI functions on Snapchat, in order to generate improvement proposals that allow its development within the app. To achieve this, a qualitative analysis was carried out through interviews to people who usually use the application, revealing their satisfaction or dissatisfaction with the usefulness of the AI. In addition, the background of the company and its introduction in these algorithms were analyzed. Furthermore, the characteristics of the three main functions of AI were explained: identify songs, solve mathematical problems, and recognize plants. As a result, it was obtained that 50% still do not know the characteristics of AI, 50% still believe song recognition is not always correct, 41.7% believe that math problems are usually accurate and 91.7% believes the plant detection tool is working properly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title="artificial intelligence">artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=scanning" title=" scanning"> scanning</a>, <a href="https://publications.waset.org/abstracts/search?q=Snapchat" title=" Snapchat"> Snapchat</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a> </p> <a href="https://publications.waset.org/abstracts/151231/snapchats-scanning-feature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151231.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">134</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">348</span> Analyzing the Oil and Gas Exploration Opportunities in Poland: Five Prospective Areas Selected and Dedicated to the Tender</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Krystian%20W%C3%B3jcik">Krystian Wójcik</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Wr%C3%B3blewska"> Sara Wróblewska</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcin%20%C5%81ojek"> Marcin Łojek</a>, <a href="https://publications.waset.org/abstracts/search?q=Katarzyna%20Sobie%C5%84"> Katarzyna Sobień</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Polish Geological Survey selected five of the most prospective areas for oil and gas exploration in Poland.

RSA encryption algorithm is suitable for such application with low data size. In this paper the design and implementation of 1024 bit-key RSA encryption and decryption module on an FPGA is presented. The module is verified through comparing the result with that obtained from MATLAB tools. The design runs at a frequency of 36.3 MHz on Virtex-5 Xilinx FPGA. The key size is designed to be 1024-bit to achieve high security for the passport information. The whole design is achieved through VHDL design entry which makes it a portable design and can be directed to any hardware platform. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RSA" title="RSA">RSA</a>, <a href="https://publications.waset.org/abstracts/search?q=VHDL" title=" VHDL"> VHDL</a>, <a href="https://publications.waset.org/abstracts/search?q=FPGA" title=" FPGA"> FPGA</a>, <a href="https://publications.waset.org/abstracts/search?q=modular%20multiplication" title=" modular multiplication"> modular multiplication</a>, <a href="https://publications.waset.org/abstracts/search?q=modular%20exponential" title=" modular exponential"> modular exponential</a> </p> <a href="https://publications.waset.org/abstracts/4249/fpga-implementation-of-rsa-encryption-algorithm-for-e-passport-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4249.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">389</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">346</span> Selection of Relevant Servers in Distributed Information Retrieval System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benhamouda%20Sara">Benhamouda Sara</a>, <a href="https://publications.waset.org/abstracts/search?q=Guezouli%20Larbi"> Guezouli Larbi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, the dissemination of information touches the distributed world, where selecting the relevant servers to a user request is an important problem in distributed information retrieval. During the last decade, several research studies on this issue have been launched to find optimal solutions and many approaches of collection selection have been proposed. In this paper, we propose a new collection selection approach that takes into consideration the number of documents in a collection that contains terms of the query and the weights of those terms in these documents. We tested our method and our studies show that this technique can compete with other state-of-the-art algorithms that we choose to test the performance of our approach. <p
