Four specimens were prepared with the same geometry, steel reinforcements, concrete properties, and span lengths. The anchored beams had a similar number of CFRP sheets but were secured utilizing different arrangements of CFRP fiber anchors. That will allow for effective and easily making comparisons to examine the flexural strengthening behavior of sand-lightweight Perlite concrete beams with anchors. The experimental outcomes were also compared with the numerical study and the comparisons were discussed. The test results showed an improvement in flexural behavior due to the use of CFRP sheets and anchors. Interestingly, the anchored beams recorded similar ultimate strength regardless of the number of CFRP fiber anchors used due to the failure by excessive wide cracks in the concrete. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=perlite%20concrete" title="perlite concrete">perlite concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=CFRP%20fiber%20anchors" title=" CFRP fiber anchors"> CFRP fiber anchors</a>, <a href="https://publications.waset.org/abstracts/search?q=lightweight%20concrete" title=" lightweight concrete"> lightweight concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=full-scale%20T-beams" title=" full-scale T-beams"> full-scale T-beams</a> </p> <a href="https://publications.waset.org/abstracts/167039/using-cfrp-sheets-and-anchors-on-sand-lightweight-perlite-concrete-to-evaluate-the-flexural-behaviour-of-t-beams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167039.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">86</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">1045</span> Powers of Class p-w A (s, t) Operators Associated with Generalized Aluthge Transformations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Husein%20Mohammed%20Rashid">Mohammed Husein Mohammed Rashid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Let Τ = U |Τ| be a polar decomposition of a bounded linear operator T on a complex Hilbert space with ker U = ker |T|.

Data were collected from a sample of 160 fatteners between June 2010 and June 2011 using the multistage random sampling technique. Translog stochastic frontier production function was employed for the analysis. Results of the analysis show that technical efficiency indices varied from 0.74 to 0.98%, with a mean of 0.90%, indicating that there was no wide gap between the efficiency of best technical efficient fatteners and that of the average fattener. The result also showed that fattening experience and herd size influenced the level of technical efficiency at 1% levels. It is recommended that credit agencies should ensure that credit made available to the fatteners is monitored to ensure appropriate utilization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=technical%20efficiency" title="technical efficiency">technical efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=determinants" title=" determinants"> determinants</a>, <a href="https://publications.waset.org/abstracts/search?q=cattle" title=" cattle"> cattle</a>, <a href="https://publications.waset.org/abstracts/search?q=fattening%20enterprises" title=" fattening enterprises"> fattening enterprises</a> </p> <a href="https://publications.waset.org/abstracts/48489/analysis-of-technical-efficiency-and-its-determinants-among-cattle-fattening-enterprises-in-kebbi-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48489.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">451</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">1043</span> Assessment of Solid Waste Management in General Mohammed Inuwa Wushishi Housing Estate, Minna, Niger State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Garba%20Inuwa%20Kuta">Garba Inuwa Kuta</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed"> Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Adamu"> Adamu</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Ahmed%20Emigilati"> Mohammed Ahmed Emigilati</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Ishiaku"> Ibrahim Ishiaku</a>, <a href="https://publications.waset.org/abstracts/search?q=Kudu%20Dangana"> Kudu Dangana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study sought to identify the problems of solid waste management in General Mohammed InuwaWushishi Housing Estate. The two broad types of data, the secondary and primary data were used in the study. Questionnaires and personal observations were also used to collect some of the data. Factors impeding the effective and efficient solid waste management were identified. The study revealed that sacks disposal method and open dumping are the most commonly used method of disposal, about 30.0% of the respondent use sacks disposal method in the estate while 24.9% dump their refuse on the floor. Wrong attitudes and perceptions of the people about sanitation issues contributed to solid waste management problems of General Mohammed InuwaWushishi Housing Estate. Majority of the households did not educate their members on the need to clean their surroundings and refuse to buy drum for waste disposal from Niger State Environmental Protection Agency (NISEPA) on the basis that the drums are expensive. Virtually, all the people depended on Niger State Environmental Protection Agency (NISEPA) facilities for the disposal of their household refuse. Solid waste management problems were partly the results of NISEPA’s inability to cope with the situation because of lack of equipment. It was recommended that there should be an increase in enlightenment to the people on domestic waste disposal to keep the surroundings clean. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=housing%20estate" title="housing estate">housing estate</a>, <a href="https://publications.waset.org/abstracts/search?q=assessment" title=" assessment"> assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20waste" title=" solid waste"> solid waste</a>, <a href="https://publications.waset.org/abstracts/search?q=disposal" title=" disposal"> disposal</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a> </p> <a href="https://publications.waset.org/abstracts/29043/assessment-of-solid-waste-management-in-general-mohammed-inuwa-wushishi-housing-estate-minna-niger-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29043.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">650</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">1042</span> EPD as Technical Competencies Acceleration Program in Developing New Talent at HR Directorate, Pertamina Ltd.</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20A.%20A.%20Indira%20Pratyaksa">A.

Zaki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a detailed numerical investigation into the structural performance of splay anchor configurations for strengthening concrete beams with Carbon Fiber Reinforced Polymer (CFRP) sheets. CFRP is widely used in retrofitting concrete structures to improve flexural strength and extend service life. However, premature debonding limits the tensile capacity of CFRP sheets, reducing the effectiveness of these applications. This study addresses this limitation by exploring the potential of splay anchors as an emerging anchorage technique that mitigates debonding issues through improved load transfer mechanisms. Building on existing experimental studies, the research uses ABAQUS software to validate different splay anchor configurations and simulate real-world performance. The parametric study examines key anchor parameters, including diameter, spacing, and embedment depth, to evaluate their effects on bond strength, load distribution, and the flexural capacity of strengthened beams. Systematic analysis of these parameters allows for identifying configurations that enhance debonding resistance and increase the load-carrying capacity of CFRP-strengthened beams. Improved debonding resistance contributes to greater structural durability, reduced maintenance costs, and extended service life for retrofitted structures, particularly relevant for aging infrastructure like bridges and buildings. This approach not only advances sustainable retrofitting practices but also provides practical solutions tailored to infrastructure demands. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFRP%20strengthening" title="CFRP strengthening">CFRP strengthening</a>, <a href="https://publications.waset.org/abstracts/search?q=splay%20anchors" title=" splay anchors"> splay anchors</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete%20beams" title=" concrete beams"> concrete beams</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20retrofitting" title=" structural retrofitting"> structural retrofitting</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20analysis" title=" numerical analysis"> numerical analysis</a> </p> <a href="https://publications.waset.org/abstracts/194468/numerical-study-of-splay-anchors-in-cfrp-strengthened-concrete-beams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194468.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">7</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">1040</span> Women Entrepreneurs’ in Nigeria: Issues and Challenges</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Mainoma">Mohammed Mainoma</a>, <a href="https://publications.waset.org/abstracts/search?q=Abubakar%20Tijanni"> Abubakar Tijanni</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Aliyu"> Mohammed Aliyu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Globalization has brought a structural change in industry. It is the breaking of artificial boundaries and given way to new product, new service, new market, and new technology among others. It leads to the realization that men entrepreneurs’ alone cannot meet the demand of the teeming population. Therefore there is a need for the participation, involvement, and engagement of females in the production and distribution of goods and services. This will enhance growth and development of a nation. It is in line with the above that this paper attempt to discuss meaning of women entrepreneurs, roles, types, problems, and prospects.

The paper analyses a television interview with the Crown Prince Mohammed Bin Salman who talks about the progress of the Saudi vision of 2030, and how the government had acted as response to the COVID-19 pandemic. The interview was on 28/4/2021. The paper analyses the tweets on Twitter that cover the interview for the purpose of investigating the development of concepts and meanings regarding the Saudi peoples’ orientations towards the Saudi projects. The data include all related tweets from the day of the interview and the following seven days after the interview. The finding of the collocation analysis suggests that nationalism notion is explicitly expressed by users in Twitter. The main finding of this paper suggests the importance of further analyses for the concordance lines. However, the collocation network suggests that there is a clear highlight for nationalism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20media" title="social media">social media</a>, <a href="https://publications.waset.org/abstracts/search?q=twitter" title=" twitter"> twitter</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20interview" title=" political interview"> political interview</a>, <a href="https://publications.waset.org/abstracts/search?q=prince%20Mohammed%20Bin%20Salman" title=" prince Mohammed Bin Salman"> prince Mohammed Bin Salman</a>, <a href="https://publications.waset.org/abstracts/search?q=Saudi%20vision%202030" title=" Saudi vision 2030"> Saudi vision 2030</a> </p> <a href="https://publications.waset.org/abstracts/146201/analysing-social-media-coverage-of-political-speeches-in-relation-to-discourse-and-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146201.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">191</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">1038</span> Serological Screening of Cytomegalovirus Infection among Sudanese Patients with Leukemia, Breast and Prostate Cancers at Radiation-Isotope Center in Khartoum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abuelquasim.%20M.%20Hassan">Abuelquasim.

Objectives: This study was conducted to determine the seroprevalence of human cytomegalovirus (HCMV) among leukemia, breast and prostate cancer patients attending at Radiation Isotope-Center-Khartoum (RICK) from April to August 2016. Material and Methods: A total of 91 subjects were included: 30 leukemic, 22 breast cancer and 29 prostate cancer patients.10 of them were healthy and used as control group, serum samples were collected and tested for CMV IgG & IgM using enzyme-linked immune sorbent assay (ELISA). Result: Of the control group, 9/10 (9.9%) were seropositive for CMV IgG and 1/10 (1.09%) were sero positive for IgM. Also, all cancer groups demonstrated presence of IgG antibody classes as: The percentage of positive results in prostate, breast cancer and leukemia were 35.8 %, 37.2%, and 35.3% respectively. Conclusion: There was no significant correlation between leukemia, breast, prostate and HCMV. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cytomegalovirus" title="cytomegalovirus">cytomegalovirus</a>, <a href="https://publications.waset.org/abstracts/search?q=serodiagnostic" title=" serodiagnostic"> serodiagnostic</a>, <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=leukemia" title=" leukemia"> leukemia</a> </p> <a href="https://publications.waset.org/abstracts/57018/serological-screening-of-cytomegalovirus-infection-among-sudanese-patients-with-leukemia-breast-and-prostate-cancers-at-radiation-isotope-center-in-khartoum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57018.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">1037</span> Characterization of Fish Bone Catalyst for Biodiesel Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarina%20Sulaiman">Sarina Sulaiman</a>, <a href="https://publications.waset.org/abstracts/search?q=N.Khairudin"> N.Khairudin </a>, <a href="https://publications.waset.org/abstracts/search?q=P.Jamal"> P.Jamal</a>, <a href="https://publications.waset.org/abstracts/search?q=M.Z.%20Alam"> M.Z.

In this study, the effect of process temperature and biomass-to-water ratio (B/W) on the fuel properties of hydrochar produced from wood shavings was investigated. HTC was conducted in an autoclave using reaction temperature of 230 °C and 260 °C for 20 minutes with B/W ratio of 0.11 to 0.43. The produced hydrochars were characterised by the mass yield (MY), higher heating value (HHV), proximate and ultimate properties. The results showed that the properties of the hydrochars improved with increasing process temperature and B/W ratio. The higher heating value (HHV) increased to 26.74 MJ/kg as the severity of the reaction was increased to the process temperature of 260 °C. Also, the atomic H/C and O/C ratios of hydrochars produced at 230 °C and 260 °C were closed to the regions of a peat and lignite on the plotted van Krevelen diagram. Hence, the produced hydrochar has a promising potential as a sustainable solid biofuel for energy application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wood%20shavings" title="wood shavings">wood shavings</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass%2Fwater%20ratio" title=" biomass/water ratio"> biomass/water ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=thermochemical%20conversion" title=" thermochemical conversion"> thermochemical conversion</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrothermal%20carbonization" title=" hydrothermal carbonization"> hydrothermal carbonization</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrochar" title=" hydrochar"> hydrochar</a> </p> <a href="https://publications.waset.org/abstracts/172680/solid-biofuel-production-by-hydrothermal-carbonization-of-wood-shavings-effect-of-carbonization-temperature-and-biomass-to-water-ratio-on-hydrochars-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172680.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">116</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">1034</span> The Impact of Varying the Detector and Modulation Types on Inter Satellite Link (ISL) Realizing the Allowable High Data Rate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asmaa%20Zaki%20M.">Asmaa Zaki M.</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Abd%20El%20Aziz"> Ahmed Abd El Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Heba%20A.%20Fayed"> Heba A.

The obtained 3-dimensional model allows computing pair radial and orientational distribution functions in order to explore the structural features of the system. Unrealistic features appeared in some coordination peaks. To remedy to this, we use the Hybrid Reverse Monte Carlo (HRMC), incorporating an additional energy constraint in addition to the usual constraints derived from experiments. The energy of the system is calculated using an Environment Dependence Interaction Potential (EDIP). Ions effects is studied by comparing correlations between water molecules in the solution and in pure water at room temperature Our results show a good agreement between experimental and computed partial distribution functions (PDFs) as well as a significant improvement in orientational distribution curves. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LiCl6H2O" title="LiCl6H2O">LiCl6H2O</a>, <a href="https://publications.waset.org/abstracts/search?q=glassy%20state" title=" glassy state"> glassy state</a>, <a href="https://publications.waset.org/abstracts/search?q=RMC" title=" RMC"> RMC</a>, <a href="https://publications.waset.org/abstracts/search?q=HRMC" title=" HRMC"> HRMC</a> </p> <a href="https://publications.waset.org/abstracts/38320/orientational-pair-correlation-functions-modelling-of-the-licl6h2o-by-the-hybrid-reverse-monte-carlo-using-an-environment-dependence-interaction-potential" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38320.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">471</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">1031</span> Models to Estimate Monthly Mean Daily Global Solar Radiation on a Horizontal Surface in Alexandria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20R.%20Abdelaziz">Ahmed R.

Methane has the potential of causing global warming 25 times more than CO₂, and can potentially affect human life and environment. Thus, this research aims to determine MSW generation and the annual CH₄ emissions from the generated waste in Oman over the years 1971-2030. The estimation of total waste generation was performed using existing models, while the CH₄ emissions estimation was performed using the intergovernmental panel on climate change (IPCC) default method. It is found that total MSW generation in Oman might be reached 3,089 Gg in the year 2030, which approximately produced 85 Gg of CH₄ emissions in the year 2030. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=methane" title="methane">methane</a>, <a href="https://publications.waset.org/abstracts/search?q=emissions" title=" emissions"> emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=landfills" title=" landfills"> landfills</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20waste" title=" solid waste"> solid waste</a> </p> <a href="https://publications.waset.org/abstracts/36440/quantification-of-methane-emissions-from-solid-waste-in-oman-using-ipcc-default-methodology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36440.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">510</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">1028</span> A Developmental Study of the Flipped Classroom Approach on Students’ Learning in English Language Modules in British University in Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20T.%20Zaki">A.

The paper concludes with recommendations of how the experience can be further developed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=achievement%20rates" title="achievement rates">achievement rates</a>, <a href="https://publications.waset.org/abstracts/search?q=developmental%20experience" title=" developmental experience"> developmental experience</a>, <a href="https://publications.waset.org/abstracts/search?q=Egypt" title=" Egypt"> Egypt</a>, <a href="https://publications.waset.org/abstracts/search?q=flipped%20classroom" title=" flipped classroom"> flipped classroom</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title=" higher education"> higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20cohorts" title=" student cohorts"> student cohorts</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20satisfaction" title=" student satisfaction"> student satisfaction</a> </p> <a href="https://publications.waset.org/abstracts/67181/a-developmental-study-of-the-flipped-classroom-approach-on-students-learning-in-english-language-modules-in-british-university-in-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67181.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">258</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1027</span> Morphological Features Fusion for Identifying INBREAST-Database Masses Using Neural Networks and Support Vector Machines </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nadia%20el%20Atlas">Nadia el Atlas</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20el%20Aroussi"> Mohammed el Aroussi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Wahbi"> Mohammed Wahbi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper a novel technique of mass characterization based on robust features-fusion is presented. The proposed method consists of mainly four stages: (a) the first phase involves segmenting the masses using edge information’s. (b) The second phase is to calculate and fuse the most relevant morphological features. (c) The last phase is the classification step which allows us to classify the images into benign and malignant masses. In this step we have implemented Support Vectors Machines (SVM) and Artificial Neural Networks (ANN), which were evaluated with the following performance criteria: confusion matrix, accuracy, sensitivity, specificity, receiver operating characteristic ROC, and error histogram. The effectiveness of this new approach was evaluated by a recently developed database: INBREAST database. The fusion of the most appropriate morphological features provided very good results. The SVM gives accuracy to within 64.3%. Whereas the ANN classifier gives better results with an accuracy of 97.5%. <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=CAD%20system" title=" CAD system"> CAD system</a>, <a href="https://publications.waset.org/abstracts/search?q=features" title=" features"> features</a>, <a href="https://publications.waset.org/abstracts/search?q=fusion" title=" fusion"> fusion</a> </p> <a href="https://publications.waset.org/abstracts/22407/morphological-features-fusion-for-identifying-inbreast-database-masses-using-neural-networks-and-support-vector-machines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22407.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">599</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">1026</span> An Analysis of the Influence of Employee Readiness for Change on TQM Implementation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20%20Haffar">Mohamed Haffar</a>, <a href="https://publications.waset.org/abstracts/search?q=Khalil%20Al-Hyari"> Khalil Al-Hyari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Khair%20Abu%20Zaid"> Mohammed Khair Abu Zaid</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramadane%20Djbarni"> Ramadane Djbarni</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Hamdan"> Mohammed Hamdan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> While employee readiness for change (ERFC) is recognised as critical for total quality management (TQM) implementation, there is a lack of systematic and empirical studies regarding the relationship between ERFC dimensions and TQM. Therefore, this study proposes to fill this gap by providing empirical evidence leading to advancement in the understanding of the influences of ERFC components on TQM implementation. The empirical data for this study was drawn from a survey of 400 middle and senior managers of Jordanian firms. The analysis of the collected data, which was conducted using Structural Equation Modeling technique, revealed that three of the ERFC components, namely personally beneficial, change self-efficacy and management support are the most supportive ERFC dimensions for TQM implementation. Therefore, this paper makes a novel contribution by providing a refined and deeper comprehension of the relationships between ERFCs and TQM implementation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=total%20quality%20management" title="total quality management">total quality management</a>, <a href="https://publications.waset.org/abstracts/search?q=employee%20readiness%20for%20change" title=" employee readiness for change"> employee readiness for change</a>, <a href="https://publications.waset.org/abstracts/search?q=manufacturing%20organisations" title=" manufacturing organisations"> manufacturing organisations</a>, <a href="https://publications.waset.org/abstracts/search?q=Jordan" title=" Jordan"> Jordan</a> </p> <a href="https://publications.waset.org/abstracts/51327/an-analysis-of-the-influence-of-employee-readiness-for-change-on-tqm-implementation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51327.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">559</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">1025</span> Cadmium Removal from Aqueous Solution Using Chitosan Beads Prepared from Shrimp Shell Extracted Chitosan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bendjaballah%20Malek%3B%20Makhlouf%20Mohammed%20Rabeh%3B%20Boukerche%20Imane%3B%20Benhamza%20Mohammed%20El%20Hocine">Bendjaballah Malek; Makhlouf Mohammed Rabeh; Boukerche Imane; Benhamza Mohammed El Hocine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, chitosan was derived from Parapenaeus longirostris shrimp shells sourced from a local market in Annaba, eastern Algeria. The extraction process entailed four chemical stages: demineralization, deproteinization, decolorization, and deacetylation. The degree of deacetylation was calculated to be 80.86 %. The extracted chitosan was physically altered to synthesize chitosan beads and characterized via FTIR and XRD analysis. These beads were employed to eliminate cadmium ions from synthetic water. The batch adsorption process was optimized by analyzing the impact of contact time, pH, adsorbent dose, and temperature. The adsorption capacity of and Cd+2 on chitosan beads was found to be 6.83 mg/g and 7.94 mg/g, respectively. The kinetic adsorption of Cd+2 conformed to the pseudo-first-order model, while the isotherm study indicated that the Langmuir Isotherm model well described the adsorption of cadmium . A thermodynamic analysis demonstrated that the adsorption of Cd+2 on chitosan beads is spontaneous and exothermic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cd" title="Cd">Cd</a>, <a href="https://publications.waset.org/abstracts/search?q=chitosan" title=" chitosan"> chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=chitosanbeds" title=" chitosanbeds"> chitosanbeds</a>, <a href="https://publications.waset.org/abstracts/search?q=bioadsorbent" title=" bioadsorbent"> bioadsorbent</a> </p> <a href="https://publications.waset.org/abstracts/167473/cadmium-removal-from-aqueous-solution-using-chitosan-beads-prepared-from-shrimp-shell-extracted-chitosan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167473.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">101</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">1024</span> On the Performance of Improvised Generalized M-Estimator in the Presence of High Leverage Collinearity Enhancing Observations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Habshah%20Midi">Habshah Midi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20A.%20Mohammed"> Mohammed A.

The ridge regression is the commonly used method to rectify this problem. However, the ridge regression cannot handle the problem of multicollinearity which is caused by high leverage collinearity enhancing observation (HLCEO). Since high leverage points (HLPs) are responsible for inducing multicollinearity, the effect of HLPs needs to be reduced by using Generalized M estimator. The existing GM6 estimator is based on the Minimum Volume Ellipsoid (MVE) which tends to swamp some low leverage points. Hence an improvised GM (MGM) estimator is presented to improve the precision of the GM6 estimator. Numerical example and simulation study are presented to show how HLPs can cause multicollinearity. The numerical results show that our MGM estimator is the most efficient method compared to some existing methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=identification" title="identification">identification</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20leverage%20points" title=" high leverage points"> high leverage points</a>, <a href="https://publications.waset.org/abstracts/search?q=multicollinearity" title=" multicollinearity"> multicollinearity</a>, <a href="https://publications.waset.org/abstracts/search?q=GM-estimator" title=" GM-estimator"> GM-estimator</a>, <a href="https://publications.waset.org/abstracts/search?q=DRGP" title=" DRGP"> DRGP</a>, <a href="https://publications.waset.org/abstracts/search?q=DFFITS" title=" DFFITS"> DFFITS</a> </p> <a href="https://publications.waset.org/abstracts/55345/on-the-performance-of-improvised-generalized-m-estimator-in-the-presence-of-high-leverage-collinearity-enhancing-observations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55345.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">262</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">1023</span> Improvement of Antibacterial Activity for Ceftazidime by Partially Purified Tannase from Penicillium expansum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sahira%20N.%20Muslim">Sahira N.

Mineral scales were deposited from the brine solution by cathodic polarization of the steel surface. The results show up that the anti-scaling property of the extracts could be attributed to the presence of citrulline. In solution, citrulline retards calcium sulphate precipitation via formation of a complex with the calcium cations. Thin, smooth and non adherent film formed over the steel surface, under cathodic polarization, by the deposition of the calcium- citrulline complex.

All were subjected to anthropometry, biochemical analysis and abdominal ultrasongraphic assessment. Metabolic syndrome (MS) was diagnosed according to the IDF criteria. Significant association between presence of MS and NAFLD was observed. Obese adolescents with NAFLD had significantly higher levels of ALT, triglycerides, fasting glucose, insulin, blood pressure and HOMA-IR, whereas decreased HDL-C levels as compared with obese cases without NAFLD. Receiver–operating characteristic (ROC) curve analysis shows that ALT is a sensitive predictor for NAFLD, confirming that ALT can be used as a marker of NAFLD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=obesity" title="obesity">obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=NAFLD" title=" NAFLD"> NAFLD</a>, <a href="https://publications.waset.org/abstracts/search?q=predictors" title=" predictors"> predictors</a>, <a href="https://publications.waset.org/abstracts/search?q=adolescents" title=" adolescents"> adolescents</a>, <a href="https://publications.waset.org/abstracts/search?q=Egyptians" title=" Egyptians"> Egyptians</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=prevalence" title=" prevalence "> prevalence </a> </p> <a href="https://publications.waset.org/abstracts/8335/predictors-of-non-alcoholic-fatty-liver-disease-in-egyptian-obese-adolescents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8335.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">390</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">1018</span> Antitrypanosomal Activity of Stigmasterol: An in silico Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Auwal%20Ibrahim">Mohammed Auwal Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Aminu%20Mohammed"> Aminu Mohammed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Stigmasterol has previously been reported to possess antitrypanosomal activity using in vitro and in vivo models. However, the mechanism of antitrypanosomal activity is yet to be elucidated. In the present study, molecular docking was used to decipher the mode of interaction and binding affinity of stigmasterol to three known antitrypanosomal drug targets viz; adenosine kinase, ornithine decarboxylase and triose phosphate isomerase. Stigmasterol was found to bind to the selected trypanosomal enzymes with minimum binding energy of -4.2, -6.5 and -6.6 kcal/mol for adenosine kinase, ornithine decarboxylase, and triose phosphate isomerase respectively. However, hydrogen bond was not involved in the interaction of stigmasterol with all the three enzymes, but hydrophobic interaction seemed to play a vital role in the binding phenomenon which was predicted to be non-competitive like type of inhibition. It was concluded that binding to the three selected enzymes, especially triose phosphate isomerase, might be involved in the antitrypanosomal activity of stigmasterol but not mediated via a hydrogen bond interaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antitrypanosomal" title="antitrypanosomal">antitrypanosomal</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20silico" title=" in silico"> in silico</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20docking" title=" molecular docking"> molecular docking</a>, <a href="https://publications.waset.org/abstracts/search?q=stigmasterol" title=" stigmasterol"> stigmasterol</a> </p> <a href="https://publications.waset.org/abstracts/76195/antitrypanosomal-activity-of-stigmasterol-an-in-silico-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76195.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">278</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">1017</span> Accounting as Addressed in the Qur’aan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shahriar%20M.%20Saadullah">Shahriar M.

This paper identifies and analyzes the word Accounting in the Qur’aan, which is significant to know and understand. The paper uses a methodology of identifying the root word of Accounting Hasaba (حسب) in the Qur’aan with the help of Islam 360 software and analyzes the use of the relevant words derived from the root word. Then the paper attempts to connect the findings to the contemporary Accounting issues. The paper finds that the root word of Accounting Hasaba (حسب) appears in the Qur’aan 109 times but it is only used in the sense Account, Accountable, or Accounting 45 times. These words appear in 44 different verses in the Qur’aan, appearing twice in one of the verses. The paper divides these verses into 8 different themes namely, Day of Accounting, without any Accounting, Accounting of Time, Self-Accounting, Swift in Accounting, Accounting is only with God, Awareness and the Good Accounting, and Heedlessness and the Bad Accounting. The way the words Account, Accounting, and Accountable is discussed in the Qur’aan links to the contemporary accounting issues including Ethics, Agency Theory, and Internal Control. The links discovered in the paper clearly shows the timeless nature of the message of the Qur’aan. <p class="card-text"><strong>Keywords:</strong> <a
