The Rapides-des-Îles Generating Station is a Hydro-Québec hydroelectric generating station and dam located on the Ottawa River in the Abitibi-Témiscamingue administrative region of Québec. This plant, with an installed capacity of 176 MW, was commissioned in 1966. During the start-up meeting held at the site in May 2019, it was noticed that the water level upstream of the main spillway was considerably higher than the water level at the powerhouse intake. Measurements showed that the level was 229.46 m, whereas the normal operating level (NOL) and the critical maximum level (CML) used in the design were 228.60 m and 229.51 m, respectively. Considering that the water level had almost reached the maximum critical level of the structure despite a flood with a recurrence period of about 100 years, the work was suspended while the project was being decided. This is the first time since the Rapides des îles project was commissioned that a significant difference in elevation between the water level at the powerhouse (intake) and the main spillway has been observed. Following this observation, the contractor's work was suspended. The objective of this study is to identify the reason(s) for this problem and find solutions. Then determine the new upstream levels at the main spillway at which the safety of the structure is ensured and then adjust the engineering of the main spillway in the rehabilitation project accordingly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spillway" title="spillway">spillway</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitation" title=" rehabilitation"> rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20level" title=" water level"> water level</a>, <a href="https://publications.waset.org/abstracts/search?q=powerhouse" title=" powerhouse"> powerhouse</a>, <a href="https://publications.waset.org/abstracts/search?q=normal%20operating%20level" title=" normal operating level"> normal operating level</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20maximum%20level" title=" critical maximum level"> critical maximum level</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20of%20the%20structure" title=" safety of the structure"> safety of the structure</a> </p> <a href="https://publications.waset.org/abstracts/162774/rapides-des-iles-main-spillway-rehabilitation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162774.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">73</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20470</span> The Effects of Production, Transportation and Storage Conditions on Mold Growth in Compound Feeds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Cetinkaya">N.

A total of 40 feed samples were taken after 20 and 40 days of storage periods from the 10 dairy and 10 beef cattle farms following the transportation of the compound feeds from the factory. In addition, before transporting the feeds from factory immediately after production of dairy and beef cattle compound feeds, 10 from each total 20 samples were taken as 0 day. In all feed samples, chemical composition and total aflatoxin levels were determined. The aflatoxin levels in all feed samples with the exception of 2 dairy cattle feeds were below the maximum acceptable level. With the increase in storage period in dairy feeds, the aflatoxin levels were increased to 4.96 ppb only in a BS8 dairy farm. This value is below the maximum permissible level (10 ppb) in beef cattle feed. The aflatoxin levels of dairy feed samples taken after production varied between 0.44 and 2.01 ppb. Aflatoxin levels were found to be between 0.89 and 3.01 ppb in dairy cattle feeds taken on the 20<sup>th</sup> day of storage at 10 dairy cattle farm. On the 40<sup>th</sup> day, feed aflatoxin levels in the same dairy cattle farm were found between 1.12 and 7.83 ppb. The aflatoxin levels were increased to 7.83 and 6.31 ppb in 2 dairy farms, after a storage period of 40 days. These obtained aflatoxin values are above the maximum permissible level in dairy cattle feeds. The 40 days storage in pellet form in the HACCP feed safety management system can be considered as a critical control point. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aflatoxin" title="aflatoxin">aflatoxin</a>, <a href="https://publications.waset.org/abstracts/search?q=beef%20cattle%20feed" title=" beef cattle feed"> beef cattle feed</a>, <a href="https://publications.waset.org/abstracts/search?q=compound%20feed" title=" compound feed"> compound feed</a>, <a href="https://publications.waset.org/abstracts/search?q=dairy%20cattle%20feed" title=" dairy cattle feed"> dairy cattle feed</a>, <a href="https://publications.waset.org/abstracts/search?q=HACCP" title=" HACCP"> HACCP</a> </p> <a href="https://publications.waset.org/abstracts/90397/the-effects-of-production-transportation-and-storage-conditions-on-mold-growth-in-compound-feeds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90397.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">398</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">20469</span> Derivation of a Risk-Based Level of Service Index for Surface Street Network Using Reliability Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chang-Jen%20Lan">Chang-Jen Lan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Current Level of Service (LOS) index adopted in Highway Capacity Manual (HCM) for signalized intersections on surface streets is based on the intersection average delay. The delay thresholds for defining LOS grades are subjective and is unrelated to critical traffic condition. For example, an intersection delay of 80 sec per vehicle for failing LOS grade F does not necessarily correspond to the intersection capacity. Also, a specific measure of average delay may result from delay minimization, delay equality, or other meaningful optimization criteria. To that end, a reliability version of the intersection critical degree of saturation (v/c) as the LOS index is introduced. Traditionally, the level of saturation at a signalized intersection is defined as the ratio of critical volume sum (per lane) to the average saturation flow (per lane) during all available effective green time within a cycle. The critical sum is the sum of the maximal conflicting movement-pair volumes in northbound-southbound and eastbound/westbound right of ways. In this study, both movement volume and saturation flow are assumed log-normal distributions. Because, when the conditions of central limit theorem obtain, multiplication of the independent, positive random variables tends to result in a log-normal distributed outcome in the limit, the critical degree of saturation is expected to be a log-normal distribution as well. Derivation of the risk index predictive limits is complex due to the maximum and absolute value operators, as well as the ratio of random variables. A fairly accurate functional form for the predictive limit at a user-specified significant level is yielded. The predictive limit is then compared with the designated LOS thresholds for the intersection critical degree of saturation (denoted as X <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reliability%20analysis" title="reliability analysis">reliability analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=level%20of%20service" title=" level of service"> level of service</a>, <a href="https://publications.waset.org/abstracts/search?q=intersection%20critical%20degree%20of%20saturation" title=" intersection critical degree of saturation"> intersection critical degree of saturation</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20based%20index" title=" risk based index"> risk based index</a> </p> <a href="https://publications.waset.org/abstracts/112749/derivation-of-a-risk-based-level-of-service-index-for-surface-street-network-using-reliability-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112749.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">131</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">20468</span> Critical Activity Effect on Project Duration in Precedence Diagram Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salman%20Ali%20Nisar">Salman Ali Nisar</a>, <a href="https://publications.waset.org/abstracts/search?q=Koshi%20Suzuki"> Koshi Suzuki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Precedence Diagram Method (PDM) with its additional relationships i.e., start-to-start, finish-to-finish, and start-to-finish, between activities provides more flexible schedule than traditional Critical Path Method (CPM).

But, changing the duration of critical activities in the PDM network will have an anomalous effect on the critical path and the project completion date. In this study, we classified the critical activities in two groups i.e., 1. activity on single critical path and 2. activity on multi-critical paths, and six classes i.e., normal, reverse, neutral, perverse, decrease-reverse and increase-normal, based on their effects on project duration in PDM. Furthermore, we determined the maximum float of time by which the duration each type of critical activities can be changed without effecting the project duration. This study would help the project manager to clearly understand the behavior of each critical activity on critical path, and he/she would be able to change the project duration by shortening or lengthening activities based on project budget and project deadline. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction%20management" title="construction management">construction management</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20path%20method" title=" critical path method"> critical path method</a>, <a href="https://publications.waset.org/abstracts/search?q=project%20scheduling%20network" title=" project scheduling network"> project scheduling network</a>, <a href="https://publications.waset.org/abstracts/search?q=precedence%20diagram%20method" title=" precedence diagram method"> precedence diagram method</a> </p> <a href="https://publications.waset.org/abstracts/97001/the-effect-of-critical-activity-on-critical-path-and-project-duration-in-precedence-diagram-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97001.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">222</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">20466</span> The Investigation on Pre-Service Teachers' Critical Thinking Dispositions in Terms of Several Variables</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C%C3%BCneyit%20Akar">Cüneyit Akar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Ba%C5%9Faran"> Mustafa Başaran</a>, <a href="https://publications.waset.org/abstracts/search?q=Ufuk%20Ulu%C3%A7%C4%B1nar"> Ufuk Uluçınar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this research is to examine the critical thinking dispositions of pre-service teachers in terms of several variables. In the line of this aim, we have investigated what their levels of critical thinking dispositions and whether there is any significant different in their critical thinking dispositions. Also, we have examined the relations between their critical thinking dispositions and their parents’ education statues, the number of their siblings, family income levels, and their religiosity level. 202 pre-service teachers who are studying at different departments at faculty of education at Uşak University participated in this research. In study, critical thinking dispositions scale by one of researchers was utilized and its validity and reliability was performed. The findings indicate that the level of their critical thinking dispositions was found to be .376 (arithmetic mean). On the other hand, we found that there is no significant difference in terms of their gender and the department at which they are studying. Furthermore, although there aren’t significant relationships between critical thinking dispositions and their mother education statues, their income levels, their religiosity levels and the number of their siblings; there is any significant positively at low level the relation between thinking dispositions and father educational statues.

The researcher used a descriptive analytical method by using the content analyzing design. An instrument was created for this purpose and tested for validity and reliability. Results showed that, all activities included critical thinking skills with different ratios as follow: conclusion skill was (87.72%), induction skill was (80.90%), interpretation skill was (77. 72%), discussion of evaluation skill was (68.64%), and assumption skill was (50.45%). Also, the study results indicated that, the level of inclusion of critical thinking skills in the scientific activities was more explicit than implicit with same order as the level of inclusions. In the light of the study's results, the researcher provided some recommendations including the need to provide and redistribute critical thinking skills in the activities listed the chemistry textbook, as well as the need to pay attention to the inclusion level of these skills more implicitly in the activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=critical%20thinking%20skills" title="critical thinking skills">critical thinking skills</a>, <a href="https://publications.waset.org/abstracts/search?q=chemistry%20textbooks" title=" chemistry textbooks"> chemistry textbooks</a>, <a href="https://publications.waset.org/abstracts/search?q=scientific%20activities" title=" scientific activities"> scientific activities</a> </p> <a href="https://publications.waset.org/abstracts/14912/critical-thinking-skills-in-activities-included-in-11th-grade-chemistry-textbook-an-analytical-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14912.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">406</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">20464</span> Effect of Nitrogen and Gibberellic Acid at Different Level and their Interaction on Calendula</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pragnyashree%20Mishra">Pragnyashree Mishra</a>, <a href="https://publications.waset.org/abstracts/search?q=Shradhanjali%20Mohapatra"> Shradhanjali Mohapatra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present investigation is carried out to know the effect of foliar feeding of nitrogen and gibberellic acid on vegetative growth, flowering behaviour and yield of calendula variety ‘Golden Emporer’.

The sample consisted of 121 students from 23 cities who are studying currently in UK universities with a mix of background variables (age, gender, and university level). A questionnaire was developed by the researcher to be used as the tool of the study. Its validity and reliability were established. The results revealed a negative correlation between knowledge of CT and the attitudes to it. It was also indicated that there exist statistically significant differences between the means of knowledge according to the university level, in favour of postgraduates. Moreover, no significant differences in the level of attitudes to CT were found according to age. Similarly, no significant differences in the knowledge of CT were found according to gender. Further, the attitudes to CT of Saudi students can be predicted based upon their university level. The findings suggest conducting further interpretive or mixed methods research with Saudi international students in order to understand the context in more depth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=critical%20thinking" title="critical thinking">critical thinking</a>, <a href="https://publications.waset.org/abstracts/search?q=Saudi%20international%20students" title=" Saudi international students"> Saudi international students</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20of%20critical%20thinking" title=" knowledge of critical thinking"> knowledge of critical thinking</a>, <a href="https://publications.waset.org/abstracts/search?q=attitudes%20towards%20critical%20thinking" title=" attitudes towards critical thinking"> attitudes towards critical thinking</a> </p> <a href="https://publications.waset.org/abstracts/129901/knowledge-of-critical-thinking-and-attitudes-towards-it-among-saudi-international-students-in-the-uk-universities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129901.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">148</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">20462</span> Improving Students' Critical Thinking in Understanding Reading Material Through Bloom's Critical Thinking Questioning Strategy in English for Specific Purposes (ESP) Class</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hevriani%20Sevrika%20Mayuasti">Hevriani Sevrika Mayuasti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research deals in improving college students’ critical thinking at English for Specific Purposes Subject.

In view of this, a comprehensive study on the distribution of the heavy metal in the groundwater was conducted to investigate the impact of urbanization in the aquatic media. Water samples either from well or borehole from Fourty different sites in and around, Durgapur, West Bengal were collected for this purpose. The samples were analyzed using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for Calcium (Ca), Cobalt (Co), Chromium (Cr), Copper (Cu), Iron (Fe), Potassium (K), Magnesium (Mg), Manganese (Mn), Sodium (Na), Nickel (Ni), Lead (Pb), Zinc (Zn) content and the levels were compared with WHO specified maximum contaminant level as well as permissible limits given by the Bureau of Indian Standards (BIS). The result obtained from the present study indicates a significant risk to the population of this important emerging ‘smart city’ of eastern India. Because of the toxicity of these metals and the fact that for many tube-wells, dug-wells and bore-wells are the only sources of the water supply for a major fraction of the population in this environment.

Usually has been noticed that criticality of surface temperature increases from the periphery to the urban centre. As the centre experiences maximum severity of heat throughout the year, it also represents most critical zone in terms of thermal condition. In this present study, an attempt has been taken to propose a quantitative approach of thermal critical zonation (TCZ) on the basis of seasonal temperature variation. Here the zonation is done by calculating thermal critical value (TCV). From the Landsat 8 thermal digital data of summer and winter seasons for the year 2014, the land surface temperature maps and thermally critical zonation has been prepared, and corresponding dataset has been computed to conduct the overall study of that particular study area. It is shown that TCZ can be clearly identified and analyzed by the help of inter-seasonal temperature range. The results of this study can be utilized effectively in future urban development and planning projects as well as a framework for implementing rules and regulations by the authorities for a sustainable urban development through an environmentally affable approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermal%20critical%20values%20%28TCV%29" title="thermal critical values (TCV)">thermal critical values (TCV)</a>, <a href="https://publications.waset.org/abstracts/search?q=thermally%20critical%20zonation%20%28TCZ%29" title=" thermally critical zonation (TCZ)"> thermally critical zonation (TCZ)</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20surface%20temperature%20%28LST%29" title=" land surface temperature (LST)"> land surface temperature (LST)</a>, <a href="https://publications.waset.org/abstracts/search?q=Landsat%208" title=" Landsat 8"> Landsat 8</a>, <a href="https://publications.waset.org/abstracts/search?q=Kolkata%20Municipal%20Corporation%20%28KMC%29" title=" Kolkata Municipal Corporation (KMC)"> Kolkata Municipal Corporation (KMC)</a> </p> <a href="https://publications.waset.org/abstracts/85395/identification-of-thermally-critical-zones-based-on-inter-seasonal-variation-in-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85395.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">197</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">20454</span> Protection of the Object of the Critical Infrastructure in the Czech Republic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michaela%20Va%C5%A1kov%C3%A1">Michaela Vašková</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the increasing dependence of countries on the critical infrastructure, it increases their vulnerability.

To estimate a safety margin against life-threatening collapse, an analytical model of the tower is subjected to a suite of ground motions with incremental intensities from maximum considered earthquake hazard level to the incipient collapse level. Capability of the structural system to collapse prevention is evaluated based on the similar methodology reported in FEMA P695. Structural performance parameters in terms of maximum/mean inter-story drift ratios, residual drift ratios, and maximum plastic hinge rotations are also compared to the acceptance criteria recommended by the TBI Guidelines. The results demonstrate that the structural system satisfactorily safeguards the building against collapse. Moreover, for this tower, the code-specified requirements in ASCE7-10 are reasonably adequate to satisfy seismic performance criteria developed in the TBI Guidelines for the maximum considered earthquake hazard level. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high-rise%20buildings" title="high-rise buildings">high-rise buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=set%20back" title=" set back"> set back</a>, <a href="https://publications.waset.org/abstracts/search?q=residual%20drift" title=" residual drift"> residual drift</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20performance" title=" seismic performance"> seismic performance</a> </p> <a href="https://publications.waset.org/abstracts/57732/a-case-study-on-the-collapse-assessment-of-the-steel-moment-frame-setback-high-rise-tower" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57732.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">260</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">20452</span> Critical Heights of Sloped Unsupported Trenches in Unsaturated Sand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Won%20Taek%20Oh">Won Taek Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Adin%20Richard"> Adin Richard</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Workers are often required to enter unsupported trenches during the construction process, which may present serious risks. Trench failures can result in death or damage to adjacent properties, therefore trenches should be excavated with extreme precaution. Excavation work is often done in unsaturated soils, where the critical height (i.e. maximum depth that can be excavated without failure) of unsupported trenches can be more reliably estimated by considering the influence of matric suction. In this study, coupled stress/pore-water pressure analyses are conducted to investigate the critical height of sloped unsupported trenches considering the influence of pore-water pressure redistribution caused by excavating. Four different wall slopes (1.5V:1H, 2V:1H, 3V:1H, and 90°) and a vertical trench with the top 0.3 m sloped 1:1 were considered in the analyses with multiple depths of the ground water table in a sand. For comparison, the critical heights were also estimated using the limit equilibrium method for the same excavation scenarios used in the coupled analyses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=critical%20height" title="critical height">critical height</a>, <a href="https://publications.waset.org/abstracts/search?q=matric%20suction" title=" matric suction"> matric suction</a>, <a href="https://publications.waset.org/abstracts/search?q=unsaturated%20soil" title=" unsaturated soil"> unsaturated soil</a>, <a href="https://publications.waset.org/abstracts/search?q=unsupported%20trench" title=" unsupported trench"> unsupported trench</a> </p> <a href="https://publications.waset.org/abstracts/98950/critical-heights-of-sloped-unsupported-trenches-in-unsaturated-sand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98950.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">121</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">20451</span> Application of Genetic Programming for Evolution of Glass-Forming Ability Parameter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manwendra%20Kumar%20Tripathi">Manwendra Kumar Tripathi</a>, <a href="https://publications.waset.org/abstracts/search?q=Subhas%20%20Ganguly"> Subhas Ganguly</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A few glass forming ability expressions in terms of characteristic temperatures have been proposed in the literature.

Only students with Grade Point Average (GPA) of at least 2.0 from four general classification of degree courses, namely: Education, Arts and Sciences, Engineering and Agriculture were included. Specific problem No.1 dealt with the profile variables, namely: age, sex, degree course, monthly family income, number of siblings, high school graduated from, grade point average, personality type, highest educational attainment of parents, and occupation of parents. Problem No. 2 determined the critical thinking index among the respondents. Problem No. 3 investigated whether or not there are significant differences in the critical thinking index among the respondents across the profile variables. While problem No.4 determined whether or not there are significant relationship between the critical thinking index and selected profile variables, namely: age, monthly family income, number of siblings, and grade point average of the respondents. Finally, on problem No. 5, the critical thinking instrument which obtained the lowest rates, were used as basis for outlining an intervention program for enhancing critical thinking index (CTI) of students. The following null hypotheses were tested at 0.05 level of significance: there are no significant differences in the critical thinking index of the third college students across the profile variables; there are no significant relationships between the critical thinking index of the respondents and selected variables, namely: age, monthly family income, number of siblings, and grade point average. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attitude%20as%20critical%20thinker" title="attitude as critical thinker">attitude as critical thinker</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20thinking%20applied" title=" critical thinking applied"> critical thinking applied</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20thinking%20index" title=" critical thinking index"> critical thinking index</a>, <a href="https://publications.waset.org/abstracts/search?q=self-perception%20as%20critical%20thinker" title=" self-perception as critical thinker"> self-perception as critical thinker</a> </p> <a href="https://publications.waset.org/abstracts/14959/critical-thinking-index-of-college-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14959.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">517</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">20449</span> Critical Mathematics Education and School Education in India: A Study of the National Curriculum Framework 2022 for Foundational Stage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eish%20Sharma">Eish Sharma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Literature around Mathematics education suggests that democratic attitudes can be strengthened through teaching and learning Mathematics. Furthermore, connections between critical education and Mathematics education are observed in the light of critical pedagogy to locate Critical Mathematics Education (CME) as the theoretical framework. Critical pedagogy applied to Mathematics education is identified as one of the key themes subsumed under Critical Mathematics Education. Through the application of critical pedagogy in mathematics, unequal power relations and social injustice can be identified, analyzed, and challenged. The research question is: have educational policies in India viewed the role of critical pedagogy applied to mathematics education (i.e., critical mathematics education) to ensure social justice as an educational aim? The National Curriculum Framework (NCF), 2005 upholds education for democracy and the role of mathematics education in facilitating the same. More than this, NCF 2005 rests on Critical Pedagogy Framework and it recommends that critical pedagogy must be practiced in all dimensions of school education. NCF 2005 visualizes critical pedagogy for social sciences as well as sciences, stating that the science curriculum, including mathematics, must be used as an “instrument for achieving social change to reduce the divide based on economic class, gender, caste, religion, and the region”. Furthermore, the implementation of NCF 2005 led to a reform in the syllabus and textbooks in school mathematics at the national level, and critical pedagogy was applied to mathematics textbooks at the primary level. This intervention led to ethnomathematics and critical mathematics education in the school curriculum in India for the first time at the national level. In October 2022, the Ministry of Education launched the National Curriculum Framework for Foundational Stage (NCF-FS), developed in light of the National Education Policy, 2020, for children in the three to eight years age group. I want to find out whether critical pedagogy-based education and critical pedagogy-based mathematics education are carried forward in NCF 2022. To find this, an argument analysis of specific sections of the National Curriculum Framework 2022 document needs to be executed. Des Gasper suggests two tables: The first table contains four columns, namely, text component, comments on meanings, possible reformulation of the same text, and identified conclusions and assumptions (both stated and unstated). This table is for understanding the components and meanings of the text and is based on Scriven’s model for understanding the components and meanings of words in the text. The second table contains four columns i.e., claim identified, given data, warrant, and stated qualifier/rebuttal. This table is for describing the structure of the argument, how and how well the components fit together and is called ‘George Table diagram based on Toulmin-Bunn Model’. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=critical%20mathematics%20education" title="critical mathematics education">critical mathematics education</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20pedagogy" title=" critical pedagogy"> critical pedagogy</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20justice" title=" social justice"> social justice</a>, <a href="https://publications.waset.org/abstracts/search?q=etnomathematics" title=" etnomathematics"> etnomathematics</a> </p> <a href="https://publications.waset.org/abstracts/165396/critical-mathematics-education-and-school-education-in-india-a-study-of-the-national-curriculum-framework-2022-for-foundational-stage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165396.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">82</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">20448</span> Study of Some Factors Effecting on Productivity of Solar Distillers </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Keshek%20M.H">Keshek M.H</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20M.A"> Mohamed M.A</a>, <a href="https://publications.waset.org/abstracts/search?q=El-Shafey%20M.A"> El-Shafey M.A</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this research was increasing the productivity of solar distillation. In order to reach this aim, a solar distiller was created with three glass sides sloping 30o at the horizontal level, and the experiments were carried out on the solar distillation unit during the period from 24th August, 2016 till 24th May, 2017 at the Agricultural Engineering and Bio Systems Department, Faculty of Agriculture, Menoufia University. Three gap lengths were used between the water level and the inner glass cover, those were 3, 6, and 9 cm. As the result of change the gap length between the water level and the inner glass cover the total volume of basins were changed from 15.5, 13, and 11 L, respectively. The total basin volume was divided to three sections, to investigate the effect of water volume. The three water volumes were 100%, 75%, and 50%. Every section was supplied with one, two, or three heaters. The one heater power was 15 W. The results showed that, by increasing the distance between the basins edge and the inner edge of the glass cover, an increase occurs in the percentage of temperature difference with maximum value was 52% at distance 9 cm from each edge, an increase occurs in the productivity with maximum productivity was 3.3 L/m2 at distance 9 cm from each edge and an increase occurs in the efficiency with maximum efficiency was 70% at distance 9 cm from each edge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distillation" title="distillation">distillation</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title=" solar energy"> solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=still%20productivity" title=" still productivity"> still productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a> </p> <a href="https://publications.waset.org/abstracts/120200/study-of-some-factors-effecting-on-productivity-of-solar-distillers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120200.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">102</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">20447</span> A Review of Critical Thinking Formative Assessment Framework: Coping with Teachers Resistance to Critical Pedagogy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chenhui%20Wang">Chenhui Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chwee%20Beng%20Lee"> Chwee Beng Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The practice of critical pedagogy is challenged by resistance from teachers. This study presents a discussion on teachers' resistance to critical pedagogy and previous practical frameworks for assessing critical thinking in formative assessment in the classroom through a critical review of the related literature. The authors found out that the main issue of teachers' resistance is not whether teachers should possess theoretical knowledge of critical thinking but how they apply that knowledge in their classroom teaching. In addition, critical thinking in formative assessment may provide teachers with a comprehensive understanding of critical pedagogical planning, implementing, and reflecting. Therefore, this paper intends to discuss a practical step-by-step framework for critical thinking formative assessment to address this resistance. Such discussion is based on a thorough examination of the related theories and frameworks. This review paper will benefit teachers in understanding and reducing their resistance to critical pedagogy as well as in implementing critical pedagogy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=critical%20thinking" title="critical thinking">critical thinking</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20pedagogy" title=" critical pedagogy"> critical pedagogy</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20thinking%20formative%20assessment%20framework" title=" critical thinking formative assessment framework"> critical thinking formative assessment framework</a>, <a href="https://publications.waset.org/abstracts/search?q=teachers%20resistance" title=" teachers resistance"> teachers resistance</a> </p> <a href="https://publications.waset.org/abstracts/155786/a-review-of-critical-thinking-formative-assessment-framework-coping-with-teachers-resistance-to-critical-pedagogy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155786.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">119</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">20446</span> Reformulation of Theory of Critical Distances to Predict the Strength of Notched Plain Concrete Beams under Quasi Static Loading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Radhika%20V.">Radhika V.</a>, <a href="https://publications.waset.org/abstracts/search?q=J.%20M.%20Chandra%20Kishen"> J.

By utilising most of the TCD's unique features, this paper summarises an attempt for a reformulation of the point method of the TCD to predict the strength of notched plain concrete beams under mode I quasi-static loading. A zone of micro cracks, which is responsible for the non-linearity of concrete, is taken into account considering the concept of an effective elastic crack. An attempt is also made to correlate the value of the material characteristic length required for the application of TCD with the maximum aggregate size in the concrete mix, eliminating the need for any extensive experimentation prior to the application of TCD. The devised reformulation and the proposed power law based relationship is found to yield satisfactory predictions for static strength of notched plain concrete beams, with geometric dimensions of the beam, tensile strength, and maximum aggregate size of the concrete mix being the only needed input parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=characteristic%20length" title="characteristic length">characteristic length</a>, <a href="https://publications.waset.org/abstracts/search?q=effective%20elastic%20crack" title=" effective elastic crack"> effective elastic crack</a>, <a href="https://publications.waset.org/abstracts/search?q=inherent%20material%20strength" title=" inherent material strength"> inherent material strength</a>, <a href="https://publications.waset.org/abstracts/search?q=modeI%20loading" title=" modeI loading"> modeI loading</a>, <a href="https://publications.waset.org/abstracts/search?q=theory%20of%20critical%20distances" title=" theory of critical distances"> theory of critical distances</a> </p> <a href="https://publications.waset.org/abstracts/154148/reformulation-of-theory-of-critical-distances-to-predict-the-strength-of-notched-plain-concrete-beams-under-quasi-static-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154148.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">98</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">20445</span> A Study on the Influence of Aswan High Dam Reservoir Loading on Earthquake Activity </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sayed%20Abdallah%20Mohamed%20Dahy">Sayed Abdallah Mohamed Dahy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aswan High Dam Reservoir extends for 500 km along the Nile River; it is a vast reservoir in southern Egypt and northern Sudan. It was created as a result of the construction of the Aswan High Dam between 1958 and 1970; about 95% of the main water resources for Egypt are from it. The purpose of this study is to discuss and understand the effect of the fluctuation of the water level in the reservoir on natural and human-induced environmental like earthquakes in the Aswan area, Egypt. In summary, the correlation between the temporal variations of earthquake activity and water level changes in the Aswan reservoir from 1982 to 2014 are investigated and analyzed. This analysis confirms a weak relation between the fluctuation of the water level and earthquake activity in the area around Aswan reservoir. The result suggests that the seismicity in the area becomes active during a period when the water level is decreasing from the maximum to the minimum. Behavior of the water level in this reservoir characterized by a special manner that is the unloading season extends to July or August, and the loading season starts to reach its maximum in October or November every year. Finally, daily rate of change in the water level did not show any direct relation with the size of the earthquakes, hence, it is not possible to be used as a single tool for prediction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aswan%20high%20dam%20reservoir" title="Aswan high dam reservoir">Aswan high dam reservoir</a>, <a href="https://publications.waset.org/abstracts/search?q=earthquake%20activity" title=" earthquake activity"> earthquake activity</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental" title=" environmental"> environmental</a>, <a href="https://publications.waset.org/abstracts/search?q=Egypt" title=" Egypt"> Egypt</a> </p> <a href="https://publications.waset.org/abstracts/35385/a-study-on-the-influence-of-aswan-high-dam-reservoir-loading-on-earthquake-activity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35385.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">380</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">20444</span> Seismic Fragility of Base-Isolated Multi-Story Piping System in Critical Facilities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bu%20Seog%20Ju">Bu Seog Ju</a>, <a href="https://publications.waset.org/abstracts/search?q=Ho%20Young%20Son"> Ho Young Son</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Hee%20Ryu"> Yong Hee Ryu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is focused on the evaluation of seismic fragility of multi-story piping system installed in critical structures, isolated with triple friction pendulum bearing.

Then, the building system and multi-story piping system was modeled in OpenSees. In particular, the triple friction pendulum isolator was accounted for the vertical and horizontal coupling behavior in the building system subjected to seismic ground motions. Consequently, in order to generate the seismic fragility of base-isolated multi-story piping system, 21 selected seismic ground motions were carried out, by using Monte Carlo Simulation accounted for the uncertainties in demand. Finally, the system-level fragility curves corresponding to the limit state of the piping system was conducted at each T-joint system, which was commonly failure points in piping systems during and after an earthquake. Additionally, the system-level fragilities were performed to the first floor and second floor level in critical structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fragility" title="fragility">fragility</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20pendulum%20bearing" title=" friction pendulum bearing"> friction pendulum bearing</a>, <a href="https://publications.waset.org/abstracts/search?q=nonstructural%20component" title=" nonstructural component"> nonstructural component</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic" title=" seismic"> seismic</a> </p> <a href="https://publications.waset.org/abstracts/96709/seismic-fragility-of-base-isolated-multi-story-piping-system-in-critical-facilities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96709.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">150</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20443</span> Magnetic Study on Ybₐ₂Cu₃O₇₋δ Nanoparticles Doped by Ferromagnetic Nanoparticles of Y₃Fe₅O₁₂</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samir%20Khene">Samir Khene</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Present and future industrial uses of high critical temperature superconductors require high critical temperatures TC and strong current densities JC.

In this work, vortices pinning in conventional and high-TC superconductors will be studied. Our experiments on vortices pinning in single crystals and nanoparticles of YBₐ₂Cu₃O₇₋δ and La₁.₈₅ Sr₀.₁₅CuO will be presented.

The ferromagnetism and superconductivity coexistence in this compound will be demonstrated, and the influence of these ferromagnetic nanoparticles on the variations of the critical current density JC in YBₐ₂Cu₃O7₇₋δ nanoparticles as a function of applied field H and temperature T will be studied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=superconductors" title="superconductors">superconductors</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20critical%20temperature" title=" high critical temperature"> high critical temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=vortices%20pinning" title=" vortices pinning"> vortices pinning</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title=" nanoparticles"> nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=ferromagnetism" title=" ferromagnetism"> ferromagnetism</a>, <a href="https://publications.waset.org/abstracts/search?q=coexistence" title=" coexistence"> coexistence</a> </p> <a href="https://publications.waset.org/abstracts/161747/magnetic-study-on-yb2cu3o7d-nanoparticles-doped-by-ferromagnetic-nanoparticles-of-y3fe5o12" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161747.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">69</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">20442</span> The Presence of Ochratoxin a in Breast-Milk, Urine and Serum of Lactating Women</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Magdalena%20Twaruzek">Magdalena Twaruzek</a>, <a href="https://publications.waset.org/abstracts/search?q=Karolina%20Ropejko"> Karolina Ropejko</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mycotoxins are secondary metabolites of molds. Ochratoxin A (OTA) is the most common in the Polish climate. It is produced by fungi of the genera Aspergillus and Penicillium. It is produced as a result of improper food storage. It is present in many products that are consumed both by humans and animals: cereals, wheat gluten, coffee, dried fruit, wine, grape juice, spices, beer, and products based on them. OTA is nephrotoxic, hepatotoxic, potentially carcinogenic, and teratogenic. OTA mainly enters an organism by oral intake. The aim of the study was to detect the presence of OTA in milk, urine, and serum of lactating women. A survey was also conducted regarding the daily diet of women. The research group consisted of 32 lactating women (11 were the donors from the Milk Bank in Toruń, the other 21 were recruited for this study). Results of the analysis showed the occurrence of OTA only in 3 milk samples (9.38%). The minimum level was 0.01 ng/ml, while the maximum 0.018 ng/ml and the mean 0.0013 ng/ml. Twenty-six urine samples (81.25%) were OTA positive, with minimum level 0.013 ng/ml, maximum level 0.117 ng/ml and mean 0.0192 ng/ml. Also, all 32 serum samples (100%) were contaminated by OTA, with a minimum level of 0.099 ng/ml, a maximum level of 2.38 ng/ml, and a mean of 0.4649 ng/ml. In the case of 3 women, OTA was present in all tested body fluids. Based on the results, the following conclusions can be drawn: the breast-milk of women in the study group is slightly contaminated with ochratoxin A. Ten samples of urine contained ochratoxin A above its average content in tested samples. Moreover, serum of 8 women contains ochratoxin A at a level above the average content of this mycotoxin in tested samples. The average ochratoxin A level in serum in the presented studies was 0.4649 ng/ml, which is much lower than the average serum ochratoxin A level established in several countries in the world, i.e., 0.7 ng/ml.
