This study investigated the incidence of Listeria monocytogenes in 80 RTE food sold in the formal (dairy and processed meat) and informal markets (vegetable salads, beef stew, and rice) of Johannesburg, South Africa. High Enterobacteriaceae, S. aureus, and E. coli counts were obtained, which ranged from 1.9-7.5 log CFU/g. Listeria monocytogenes microbial counts in the food samples ranged from 3.5-6.0 log colony forming unit per gram except in cooked rice. The Listeria monocytogenes isolates were identified using biochemical tests and confirmed with the Biolog identification system and PCR analyses. The percentage incidence for Listeria monocytogenes in ready to eat food was 12.5%. When Minimum Inhibitory Concentrations were under consideration, all disinfectants were effective against Listeria monocytogenes strains. For antimicrobial work, rates of resistance amongst the antibiotics ranged from 17-100%. Therefore, more effective preventive control strategies for Listeria monocytogenes are needed to reduce the prevalence of the pathogen in RTE food that is sold in Johannesburg. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Listeria%20monocytogenes" title="Listeria monocytogenes">Listeria monocytogenes</a>, <a href="https://publications.waset.org/abstracts/search?q=Listeria%20species" title=" Listeria species"> Listeria species</a>, <a href="https://publications.waset.org/abstracts/search?q=ready%20to%20eat%20food" title=" ready to eat food"> ready to eat food</a>, <a href="https://publications.waset.org/abstracts/search?q=sanitiser%20efficacy" title=" sanitiser efficacy"> sanitiser efficacy</a> </p> <a href="https://publications.waset.org/abstracts/114295/incidence-of-listeria-monocytogenes-in-ready-to-eat-food-sold-in-johannesburg-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114295.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">166</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">91</span> A Review of Strategies for Enhancing the Quality of Engineering Education in Zimbabwean Universities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bhekisisa%20Nyoni">Bhekisisa Nyoni</a>, <a href="https://publications.waset.org/abstracts/search?q=Nomakhosi%20Ndiweni"> Nomakhosi Ndiweni</a>, <a href="https://publications.waset.org/abstracts/search?q=Annatoria%20Chinyama"> Annatoria Chinyama</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this paper was to explore ways to enhance the quality of higher education with a bias towards engineering education in Zimbabwe universities. A search through relevant literature was conducted looking at both international and local scholars. It also involved reviewing the Dakar Framework for Action and Incheon Declaration and Framework for Action plans for education for sustainable development. Goals were set for 2030 as a standard for quality to be adopted by all countries in improving access as well as the quality of education from early childhood and through to adult learning. Despite the definition of quality being difficult to express due to diverse expectations from different stakeholders, the view of quality adopted is based on the World Education Forum’s propositions on quality education going beyond the classroom experience. It considers factors such as learning environment, governance and management, and teacher caliber. The study concludes by illustrating that the quality of engineering education in Zimbabwe has come a long way. It has made strides in increasing access and variety to education though at the expense of quality in its totality. To improve the quality of engineering education, programs have been introduced to promote the professionalism of lecturers, such as industrial secondment and professional development courses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=engineering%20education" title="engineering education">engineering education</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20education" title=" quality of education"> quality of education</a>, <a href="https://publications.waset.org/abstracts/search?q=professional%20development" title=" professional development"> professional development</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20secondment" title=" industrial secondment"> industrial secondment</a> </p> <a href="https://publications.waset.org/abstracts/137687/a-review-of-strategies-for-enhancing-the-quality-of-engineering-education-in-zimbabwean-universities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137687.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">181</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">90</span> A Tale of Seven Districts: Reviewing The Past, Present and Future of Patent Litigation Filings to Form a Two-Step Burden-Shifting Framework for 28 U.S.C. § 1404(a)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Timothy%20T.%20Hsieh">Timothy T. Hsieh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Current patent venue transfer laws under 28 U.S.C. § 1404(a) e.g., the Gilbert factors from Gulf Oil Corp. v. Gilbert, 330 U.S. 501 (1947) are too malleable in that they often lead to frequent mandamus orders from the U.S. Court of Appeals for the Federal Circuit (“Federal Circuit”) overturning district court rulings on venue transfer motions. Thus, this paper proposes a more robust two-step burden-shifting framework that replaces the eight Gilbert factors. Moreover, a brief history of venue transfer patterns in the seven most active federal patent district courts is covered, with special focus devoted to the venue transfer orders from Judge Alan D Albright of the U.S. District Court for the Western District of Texas. A comprehensive data summary of 45 case sets where the Federal Circuit ruled on writs of mandamus involving Judge Albright’s transfer orders is subsequently provided, with coverage summaries of certain cases including four precedential ones from the Federal Circuit. This proposed two-step burden shifting framework is then applied to these venue transfer cases, as well as Federal Circuit mandamus orders ruling on those decisions. Finally, alternative approaches to remedying the frequent reversals for venue transfer will be discussed, including potential legislative solutions, adjustments to common law framework approaches to venue transfer, deference to the inherent powers of Article III U.S. District Judge, and a unified federal patent district court. Overall, this paper seeks to offer a more robust and consistent three-step burden-shifting framework for venue transfer and for the Federal Circuit to follow in administering mandamus orders, which might change somewhat in light of Western District of Texas Chief Judge Orlando Garcia’s order on redistributing Judge Albright’s patent cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patent%20law" title="Patent law">Patent law</a>, <a href="https://publications.waset.org/abstracts/search?q=venue" title=" venue"> venue</a>, <a href="https://publications.waset.org/abstracts/search?q=judge%20Alan%20Albright" title=" judge Alan Albright"> judge Alan Albright</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20contacts" title=" minimum contacts"> minimum contacts</a>, <a href="https://publications.waset.org/abstracts/search?q=western%20district%20of%20Texas" title=" western district of Texas"> western district of Texas</a> </p> <a href="https://publications.waset.org/abstracts/164755/a-tale-of-seven-districts-reviewing-the-past-present-and-future-of-patent-litigation-filings-to-form-a-two-step-burden-shifting-framework-for-28-usc-1404a" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164755.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">109</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">89</span> Change of Internal Friction on Magnesium Alloy with 5.48% Al Dependence on the Temperature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Milan%20Uhr%C3%AD%C4%8Dik">Milan Uhríčik</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Soviarov%C3%A1"> Andrea Soviarová</a>, <a href="https://publications.waset.org/abstracts/search?q=Zuzana%20Dresslerov%C3%A1"> Zuzana Dresslerová</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Pal%C4%8Dek"> Peter Palček</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Va%C5%A1ko"> Alan Vaško</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The article is focused on the analysis changes dependence on the temperature on the magnesium alloy with 5,48% Al, 0,813% Zn and 0,398% Mn by internal friction.

The paper is informed by the findings from the data that was generated from 154 university students who were coming from diverse backgrounds. The qualitative data was thematically analysed. Referring to the six steps of the behaviour change model, we found that African Folklore provides relevant cultural knowledge and instills values that enable young people to engage on self-reflection that eventually leads them towards attitudinal changes and behaviour modification. Using the transformative learning theory, we argue that African Folklore in itself is a pedagogical strategy that integrates cultural knowledge, values with entertainment elements concisely enough to take the young people through a transformative phase which encompasses psychological, convictional and life-style adaptation. During data production stage all ethical considerations were observed including obtaining gatekeeper’s permission letter and ethical clearance certificate from the Ethics Committee of the University. The paper recommends that African Folklore approach should be incorporated into the school curriculum particularly in life skills education with aims to change behaviour. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=African%20folklore" title="African folklore">African folklore</a>, <a href="https://publications.waset.org/abstracts/search?q=young%20people" title=" young people"> young people</a>, <a href="https://publications.waset.org/abstracts/search?q=attitudinal" title=" attitudinal"> attitudinal</a>, <a href="https://publications.waset.org/abstracts/search?q=behavior%20change" title=" behavior change"> behavior change</a>, <a href="https://publications.waset.org/abstracts/search?q=university%20students" title=" university students"> university students</a> </p> <a href="https://publications.waset.org/abstracts/70861/african-folklore-for-critical-self-reflection-reflective-dialogue-and-resultant-attitudinal-and-behaviour-change-university-students-experiences" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70861.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">263</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">86</span> Eliminating Cutter-Path Deviation For Five-Axis Nc Machining</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alan%20C.%20Lin">Alan C.

Two research objectives guided it: to determine how indigenous knowledge (IK) is developed at the University of Zululand and how indigenous knowledge (IK) is documented at the University of Zululand. The study adopted both interpretive and positivist research paradigms. Ultimately, qualitative and quantitative research methods were used. The qualitative research approach collected data from academic and non-academic staff members. Interviews were conducted with 18 academic staff members and 5 with support staff members. The quantitative research approach was used to collect data from indigenous knowledge (IK) theses and dissertations from the University of Zululand Institutional Repository between 2009-2019. The study results revealed that many departments across the University of Zululand were involved in creating indigenous knowledge (IK)-related content. The department of African Languages was noted to be more involved in creating IK-related content. Moreover, the documentation of the content related to indigenous knowledge (IK) at the University of Zululand is done frequently but is not readily known. It was found that the creation and documentation of indigenous knowledge by different departments faced several challenges. The common challenges are a lack of interest among indigenous knowledge (IK) owners in sharing their knowledge, the local language as a barrier, and a shortage of proper tools for recording and capturing indigenous knowledge (IK). One of the study recommendations is the need for an indigenous knowledge systems (IKS) policy to be in place at the University of Zululand. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knowledge%20creation" title="knowledge creation">knowledge creation</a>, <a href="https://publications.waset.org/abstracts/search?q=SECI%20model" title=" SECI model"> SECI model</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20and%20communication%20technology." title=" information and communication technology."> information and communication technology.</a>, <a href="https://publications.waset.org/abstracts/search?q=indigenous%20knowledge" title=" indigenous knowledge"> indigenous knowledge</a> </p> <a href="https://publications.waset.org/abstracts/163384/the-role-of-the-university-of-zululand-in-documenting-and-disseminating-indigenous-knowledge-in-kwazulu-natal-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163384.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">112</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">84</span> Developing an Online Library for Faster Retrieval of Mold Base and Standard Parts of Injection Molding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alan%20C.%20Lin">Alan C.

In order to delineate the border of undercut regions, orthogonal cutting planes are firstly employed to automatically find the inner loops of a part model. To discover the facets belonging to undercut regions, attributes are then assigned to the facets of the part model based on the topological relationship of adjacent facets of each inner loop. After that, the undercut regions are separated from other facets in the model. Through the recognized facets of the undercut regions, the concept of 'visibility map (V-map)' is further applied to determine feasible releasing directions for each of the undercut regions. The undercut regions having the same releasing direction are finally grouped to form a slider in the injection mold. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solid%20model" title="solid model">solid model</a>, <a href="https://publications.waset.org/abstracts/search?q=STL%20data" title=" STL data"> STL data</a>, <a href="https://publications.waset.org/abstracts/search?q=injection%20mold%20design" title=" injection mold design"> injection mold design</a>, <a href="https://publications.waset.org/abstracts/search?q=visibility%20map" title=" visibility map"> visibility map</a> </p> <a href="https://publications.waset.org/abstracts/11104/automatic-slider-design-in-injection-moldings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11104.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">395</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">82</span> Effect of Hot Rolling Conditions on Magnetic Properties of Fe-3%Si Non-Grain Oriented Electrical Steels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emre%20Alan">Emre Alan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Yamanturk"> Yusuf Yamanturk</a>, <a href="https://publications.waset.org/abstracts/search?q=Gokay%20Bas"> Gokay Bas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Non-grain oriented electrical steels are high silicon containing steels in which the direction of magnetism is intended the same in any direction of the material.

Thus, the genetic relatedness of GLM, A. simplexela, and A. modicella was examined by performing mitochondrial and nuclear (COI, cytochrome oxidase subunit II (COII), mitochondrial cytochrome b (CYTB), nuclear ribosomal 28S (28S) and intergenic spacer elongation factor-1 alpha ( EF-1 ALPHA) on 44 specimens collected from South Africa, four from Mozambique, and three each from single locations in India and Australia. Phylogenetic analyses were conducted using the Maximum Parsimony (MP) and Neighbour-Joining (NJ) methods. All of the datasets of the five DNA gene regions that were sequenced were also analyzed using the Basic Local Alignment Search Tool (BLAST) to find the closest matches for inclusion in the phylogenetic trees as outgroups and for purposes of information. In the phylogenetic trees for COI, COII, cytb and EF-1 ALPHA, a similar pattern was observed in the way that the sequences assembled into different groups; i.e., some sequences of A. simplexella from Australia were grouped separately from the others, but some Australian sequences grouped with those of the GLM from South Africa, India, and Mozambique. In the phylogenetic tree for 28S, all sequences from South Africa, Australia, India, and Mozambique grouped together and formed one group. For COI, genetic pairwise distance ranged from 0.97 to 3.60 %, for COII it ranged from 0.19% to 2.32%, for cytb it ranged from 0.25 to 9.77% and for EF-1 ALPHA it ranged 0.48 to 6.99%. Results of this study indicate that these populations are genetically related and presumably constitute a single species. Thus, further molecular and morphological studies need to be undertaken in order to resolve this apparent conundrum on the taxonomy of these populations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aproaerema%20modicella" title="aproaerema modicella">aproaerema modicella</a>, <a href="https://publications.waset.org/abstracts/search?q=aproaerema%20simplexella" title=" aproaerema simplexella"> aproaerema simplexella</a>, <a href="https://publications.waset.org/abstracts/search?q=mitochondrial%20DNA" title=" mitochondrial DNA"> mitochondrial DNA</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear%20DNA" title=" nuclear DNA"> nuclear DNA</a> </p> <a href="https://publications.waset.org/abstracts/106498/phylogenetic-relationships-of-aproaerema-simplexella-walker-and-the-groundnut-leaf-miner-aproaerema-modicella-deventer-lepidoptera-gelechiidae-collected-from-australia-india-mozambique-and-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106498.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">199</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">80</span> Prediction and Reduction of Cracking Issue in Precision Forging of Engine Valves Using Finite Element Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xi%20Yang">Xi Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Bulent%20Chavdar"> Bulent Chavdar</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Vonseggern"> Alan Vonseggern</a>, <a href="https://publications.waset.org/abstracts/search?q=Taylan%20Altan"> Taylan Altan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fracture in hot precision forging of engine valves was investigated in this paper. The entire valve forging procedure was described and the possible cause of the fracture was proposed. Finite Element simulation was conducted for the forging process, with commercial Finite Element code DEFORMTM. The effects of material properties, the effect of strain rate and temperature were considered in the FE simulation. Two fracture criteria were discussed and compared, based on the accuracy and reliability of the FE simulation results. The selected criterion predicted the fracture location and shows the trend of damage increasing with good accuracy, which matches the experimental observation. Additional modification of the punch shapes was proposed to further reduce the tendency of fracture in forging. Finite Element comparison shows a great potential of such application in the mass production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hotforging" title="hotforging">hotforging</a>, <a href="https://publications.waset.org/abstracts/search?q=engine%20valve" title=" engine valve"> engine valve</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture" title=" fracture"> fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=tooling" title=" tooling"> tooling</a> </p> <a href="https://publications.waset.org/abstracts/23033/prediction-and-reduction-of-cracking-issue-in-precision-forging-of-engine-valves-using-finite-element-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23033.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">279</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">79</span> Determination of Steel Cleanliness of Non-Grain Oriented Electrical Steels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emre%20Alan">Emre Alan</a>, <a href="https://publications.waset.org/abstracts/search?q=Zafer%20Cetin"> Zafer Cetin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrical steels are widely used as a magnetic core materials in many electrical applications such as transformers, electric motors, and generators. Core loss property of these magnetic materials refers to dissipation of electrical energy during magnetization in service conditions. Therefore, in order to minimize the magnetic core loss, certain precautions are taken from steel producers; “Steel Cleanliness” is one of the major points among them. For obtaining lower core loss values, increasing proper elements in chemical composition such as silicon is a must. Therefore, impurities of these alloys are a key value for producing a cleaner steel. In this study, effects of impurity levels of different FeSi alloying materials to the steel cleanliness will be investigated. One of the important element content in FeSi alloy materials is Calcium. A SEM investigation will be done in order to present if Ca content in FeSi alloy is enough for proper inclusion modification or an additional Ca-treatment is required. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrical%20steels" title="electrical steels">electrical steels</a>, <a href="https://publications.waset.org/abstracts/search?q=FeSi%20alloy" title=" FeSi alloy"> FeSi alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=impurities" title=" impurities"> impurities</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20cleanliness" title=" steel cleanliness"> steel cleanliness</a> </p> <a href="https://publications.waset.org/abstracts/56726/determination-of-steel-cleanliness-of-non-grain-oriented-electrical-steels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56726.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">334</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">78</span> Measurements of Chitin by Ochratoxigenic Fungi and Its Relationship to Ochratoxin a Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jamal%20Elzwai">Jamal Elzwai</a>, <a href="https://publications.waset.org/abstracts/search?q=Kofi%20Aidoo"> Kofi Aidoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Candlish"> Alan Candlish</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Production of OTA was detected after 24hr by Aspergillus ochraceus isolate whereas at 36hr for A. carbonarius isolate and Penicillium verrucosum IMI 285522 and 60hr for A. ochraceus CBS 588.68. Highest OTA level was produced by A. carbonarius isolate followed by A. ochraceus CBS 588.68, Penicillium verrucosum IMI 285522 and finally A. ochraceus isolate. Glucosamine content of barley sample before fermentation was found to be negligible and remained almost constant during the incubation time. Glucosamine content started to increase at 12 hours after incubation with A. ochraceus isolate, A. carbonarius isolate and A. ochraceus CBS 588.68, and after 12 hours with P. verrucosum IMI 285522. Highest glucosamine content, as a result of increase in fungal biomass, was produced by A. ochraceus CBS 588.68 followed by A. ochraceus isolate, A. carbonarius isolate, and finally by P. verrucosum IMI 285522. It appears that there is a correlation between OTA synthesis and glucosamine content with A. ochraceus isolate, A. carbonarius isolate and A. ochraceus CBS 588.68 but not with P. verrucosum IMI 285522. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chitin" title="chitin">chitin</a>, <a href="https://publications.waset.org/abstracts/search?q=barley" title=" barley"> barley</a>, <a href="https://publications.waset.org/abstracts/search?q=Ochratoxin%20A" title=" Ochratoxin A"> Ochratoxin A</a>, <a href="https://publications.waset.org/abstracts/search?q=Aspergiluus%20ochraceus" title=" Aspergiluus ochraceus"> Aspergiluus ochraceus</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20carbonarius" title=" A. carbonarius"> A. carbonarius</a>, <a href="https://publications.waset.org/abstracts/search?q=Penicillium%20verrucosum" title=" Penicillium verrucosum"> Penicillium verrucosum</a> </p> <a href="https://publications.waset.org/abstracts/16117/measurements-of-chitin-by-ochratoxigenic-fungi-and-its-relationship-to-ochratoxin-a-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16117.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">430</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">77</span> Competition in Kenya: The Legal and Institutional Framework and an Appraisal of Key Market Players</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Edwin%20Njoroge%20Kimani">Edwin Njoroge Kimani</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20M.%20Munyao"> Alan M.

This, however, seems not to affect major cooperates such as those in the telecommunication and energy sectors. Through their operations, they have not only been able to fluctuate prices at will but also they have been accused of curtailing their rivals from penetrating the market. This study, through literature review of the legal and institutional framework, reports and publications interrogates the law and uncovers the following; i) failings of the legal framework to define market dominance and abuse of such positions, ii) the participation of the state, iii) the inertia of the government to prosecute corporations that abuse their market dominance, iv) the role of the state as a market player and as a regulator through the Competition Authority of Kenya. This study concludes that the market distortion is as a result of weak legal and institutional framework as well as conflict of interest by the government.

When concrete compressive strength be larger than 31 MPa the limit of √(fc')/4fy usually governs. In this paper shortcomings related to using this limit was fairly discussed and showed that the limit is based on 90% safety factor and was derived based on modulus of rupture equation suitable for concretes of compressive strength lower than 31 MPa. Accordingly, the limit is nor suitable and critical for concretes of higher compressive strength. An alternative equation was proposed for minimum steel ratio of rectangular beams and was found that the proposed limit is accurate for beams of wide range of concrete compressive strength. Shortcomings of the current ACI 318 Code equation and accuracy of the proposed equation were supported by test data obtained from testing six reinforced concrete beams. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete%20beam" title="concrete beam">concrete beam</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20steel%20ratio" title=" minimum steel ratio"> minimum steel ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=modulus%20of%20rupture" title=" modulus of rupture"> modulus of rupture</a> </p> <a href="https://publications.waset.org/abstracts/17902/minimum-ratio-of-flexural-reinforcement-for-high-strength-concrete-beams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17902.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">550</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">75</span> The High Temperature Damage of DV–2 Turbine Blade Made from Ni–Base Superalloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juraj%20Belan">Juraj Belan</a>, <a href="https://publications.waset.org/abstracts/search?q=Lenka%20Hurtalov%C3%A1"> Lenka Hurtalová</a>, <a href="https://publications.waset.org/abstracts/search?q=Eva%20Tillov%C3%A1"> Eva Tillová</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Va%C5%A1ko"> Alan Vaško</a>, <a href="https://publications.waset.org/abstracts/search?q=Milan%20Uhr%C3%AD%C4%8Dik"> Milan Uhríčik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> High-pressure turbine (HPT) blades of DV–2 jet engines are made from Ni–base superalloy, a former Soviet Union production, specified as ŽS6K.

This type of events can influence the oceanic/land interactions and even be related with climate changes. While the impact of such floods has been fairly studied in the North Atlantic, the impact of analog floods in the North Pacific remains debatable and relatively unknown. Here we will show records of the Missoula floods that have carved the Northwest landscape and have entered the North Pacific through the Columbia River. These records are given by the presence of high (more than 40%) percentages of freshwater diatoms in marine sediments. A regression equation using these percentages allows to estimate by how much the salinities decreased. The timing and impact of North Pacific megafloods recorded in three marine cores of Oregon and California for the past 25000 years (B.P.) will be presented. These records show that the volume of freshwater that entered the North Pacific reached as far as 600 Km south of the Columbia River Mouth, decreasing the salinities by as much as 4 units. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diatoms" title="diatoms">diatoms</a>, <a href="https://publications.waset.org/abstracts/search?q=megafloods" title=" megafloods"> megafloods</a>, <a href="https://publications.waset.org/abstracts/search?q=Missoula" title=" Missoula"> Missoula</a>, <a href="https://publications.waset.org/abstracts/search?q=North%20Pacific" title=" North Pacific"> North Pacific</a> </p> <a href="https://publications.waset.org/abstracts/103119/timing-and-impacts-of-megafloods-in-the-north-pacific-as-recorded-by-freshwater-diatoms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103119.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">172</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">73</span> Automated Buffer Box Assembly Cell Concept for the Canadian Used Fuel Packing Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dimitrie%20Marinceu">Dimitrie Marinceu</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Murchison"> Alan Murchison</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Canadian Used Fuel Container (UFC) is a mid-size hemispherical headed copper coated steel container measuring 2.5 meters in length and 0.5 meters in diameter containing 48 used fuel bundles. The contained used fuel produces significant gamma radiation requiring automated assembly processes to complete the assembly. The design throughput of 2,500 UFCs per year places constraints on equipment and hot cell design for repeatability, speed of processing, robustness and recovery from upset conditions. After UFC assembly, the UFC is inserted into a Buffer Box (BB). The BB is made from adequately pre-shaped blocks (lower and upper block) and Highly Compacted Bentonite (HCB) material. The blocks are practically ‘sandwiching’ the UFC between them after assembly. This paper identifies one possible approach for the BB automatic assembly cell and processes. Automation of the BB assembly will have a significant positive impact on nuclear safety, quality, productivity, and reliability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=used%20fuel%20packing%20plant" title="used fuel packing plant">used fuel packing plant</a>, <a href="https://publications.waset.org/abstracts/search?q=automatic%20assembly%20cell" title=" automatic assembly cell"> automatic assembly cell</a>, <a href="https://publications.waset.org/abstracts/search?q=used%20fuel%20container" title=" used fuel container"> used fuel container</a>, <a href="https://publications.waset.org/abstracts/search?q=buffer%20box" title=" buffer box"> buffer box</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20geological%20repository" title=" deep geological repository"> deep geological repository</a> </p> <a href="https://publications.waset.org/abstracts/75488/automated-buffer-box-assembly-cell-concept-for-the-canadian-used-fuel-packing-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75488.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">275</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">72</span> Cooperative Jamming for Implantable Medical Device Security</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kim%20Lytle">Kim Lytle</a>, <a href="https://publications.waset.org/abstracts/search?q=Tim%20Talty"> Tim Talty</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Michaels"> Alan Michaels</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeff%20Reed"> Jeff Reed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Implantable medical devices (IMDs) are medically necessary devices embedded in the human body that monitor chronic disorders or automatically deliver therapies. Most IMDs have wireless capabilities that allow them to share data with an offboard programming device to help medical providers monitor the patient’s health while giving the patient more insight into their condition. However, serious security concerns have arisen as researchers demonstrated these devices could be hacked to obtain sensitive information or harm the patient. Cooperative jamming can be used to prevent privileged information leaks by maintaining an adequate signal-to-noise ratio at the intended receiver while minimizing signal power elsewhere. This paper uses ray tracing to demonstrate how a low number of friendly nodes abiding by Bluetooth Low Energy (BLE) transmission regulations can enhance IMD communication security in an office environment, which in turn may inform how companies and individuals can protect their proprietary and personal information. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=implantable%20biomedical%20devices" title="implantable biomedical devices">implantable biomedical devices</a>, <a href="https://publications.waset.org/abstracts/search?q=communication%20system%20security" title=" communication system security"> communication system security</a>, <a href="https://publications.waset.org/abstracts/search?q=array%20signal%20processing" title=" array signal processing"> array signal processing</a>, <a href="https://publications.waset.org/abstracts/search?q=ray%20tracing" title=" ray tracing"> ray tracing</a> </p> <a href="https://publications.waset.org/abstracts/167002/cooperative-jamming-for-implantable-medical-device-security" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167002.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">112</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">71</span> Perceptions of Mothers on Their Role in the Prevention of the Spread of Human Immunodeficiency Virus to Their Children and Childcare Received in the Healthcare Facility in a Rural Area</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sibusiso%20Buthelezi">Sibusiso Buthelezi</a>, <a href="https://publications.waset.org/abstracts/search?q=Rugira%20Regis%20Marie-Modeste"> Rugira Regis Marie-Modeste</a>, <a href="https://publications.waset.org/abstracts/search?q=Deliwe%20Rene%20Phetlhu"> Deliwe Rene Phetlhu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Mother-to-child transmission persists owing to inadequate implementation of prevention of mother-to-child transmission programmes, particularly in rural areas. To achieve a target of zero new HIV infection in children born from women living with HIV, the involvement of mothers and caregivers is undeniable. Therefore, there is a need to explore the views of the mothers because of the role they play in their own right when it comes to preventing their children from contracting HIV by consistently adhering to the guidelines of the prevention of mother-to-child transmission programme. Thus, this study sought to explore and describe the perceptions of mothers on their role in the prevention of HIV to their children exposed to HIV and further explore their perceptions of the childcare received in the healthcare facility. Methods: The study was conducted in November-December 2019 in Ngaka Modiri Molema in North West Province in South Africa. A qualitative exploratory, descriptive research design was used. Purposive sampling was used to select the mothers of children exposed to HIV during the mother`s clinic attendance. Data collection was done through semi-structured individual interviews with mothers of children exposed to HIV. Colaizzi`s method of data analysis was used to analyse data in this study. Results: Seven themes emerged from data analysis, namely: health benefits from coming to the healthcare facility, communication, information needs, attitude of healthcare workers, healthcare administration system, the role of a mother, and disclosure of HIV status. Conclusion: This study revealed systematic gaps that exist in the programme, which hinder the childcare services of children exposed to HIV and socio-economically related hindrances. Mothers’ roles, such as exclusive breastfeeding, taking their own medication, and child follow-up visits, remain inadequate. The study findings show that there is a need to develop a contextual-tailored intervention strategy that would improve the implementation of prevention of mother-to-child transmission in rural areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=children%20exposed%20to%20HIV" title="children exposed to HIV">children exposed to HIV</a>, <a href="https://publications.waset.org/abstracts/search?q=mothers%E2%80%99%20role%20to%20prevent%20MTCT" title=" mothers’ role to prevent MTCT"> mothers’ role to prevent MTCT</a>, <a href="https://publications.waset.org/abstracts/search?q=mothers%E2%80%99%20perceptions%20on%20childcare" title=" mothers’ perceptions on childcare"> mothers’ perceptions on childcare</a>, <a href="https://publications.waset.org/abstracts/search?q=PMTCT%20in%20rural%20areas" title=" PMTCT in rural areas"> PMTCT in rural areas</a> </p> <a href="https://publications.waset.org/abstracts/156265/perceptions-of-mothers-on-their-role-in-the-prevention-of-the-spread-of-human-immunodeficiency-virus-to-their-children-and-childcare-received-in-the-healthcare-facility-in-a-rural-area" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156265.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">99</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">70</span> Influence of Raw Material Composition on Microstructure and Mechanical Properties of Nodular Cast Iron </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alan%20Va%C5%A1ko">Alan Vaško</a>, <a href="https://publications.waset.org/abstracts/search?q=Juraj%20Belan"> Juraj Belan</a>, <a href="https://publications.waset.org/abstracts/search?q=Lenka%20Hurtalov%C3%A1"> Lenka Hurtalová</a>, <a href="https://publications.waset.org/abstracts/search?q=Eva%20Tillov%C3%A1"> Eva Tillová</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to evaluate the influence of raw material composition on the microstructure, mechanical and fatigue properties and micromechanisms of failure of nodular cast iron. In order to evaluate the influence of charge composition, the structural analysis, mechanical and fatigue tests and micro fractographic analysis were carried out on specimens of ten melts with different charge compositions. The basic charge of individual melts was formed by a different ratio of pig iron and steel scrap and by different additive for regulation of chemical composition (silicon carbide or ferrosilicon). The results show differences in mechanical and fatigue properties, which are connected with the microstructure. SiC additive positively influences microstructure.

Most of this work focuses on models with different mean structures but leaves out the variance consideration. In this paper, we consider a regression model with multiplicative heteroscedasticity and develop a model averaging method that combines maximum likelihood estimators of unknown parameters in both the mean and variance functions of the model. Our weight choice criterion is based on a minimisation of a plug-in estimator of the model average estimator's squared prediction risk. We prove that the new estimator possesses an asymptotic optimality property. Our investigation of finite-sample performance by simulations demonstrates that the new estimator frequently exhibits very favourable properties compared to some existing heteroscedasticity-robust model average estimators. The model averaging method hedges against the selection of very bad models and serves as a remedy to variance function misspecification, which often discourages practitioners from modeling heteroscedasticity altogether. The proposed model average estimator is applied to the analysis of two real data sets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heteroscedasticity-robust" title="heteroscedasticity-robust">heteroscedasticity-robust</a>, <a href="https://publications.waset.org/abstracts/search?q=model%20averaging" title=" model averaging"> model averaging</a>, <a href="https://publications.waset.org/abstracts/search?q=multiplicative%20heteroscedasticity" title=" multiplicative heteroscedasticity"> multiplicative heteroscedasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=plug-in" title=" plug-in"> plug-in</a>, <a href="https://publications.waset.org/abstracts/search?q=squared%20prediction%20risk" title=" squared prediction risk"> squared prediction risk</a> </p> <a href="https://publications.waset.org/abstracts/68733/model-averaging-in-a-multiplicative-heteroscedastic-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68733.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">68</span> Evaluating Hourly Sulphur Dioxide and Ground Ozone Simulated with the Air Quality Model in Lima, Peru</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Od%C3%B3n%20R.%20S%C3%A1nchez-Ccoyllo">Odón R.

The objective of this research is to evaluate the effectiveness of the air-quality-WRF-Chem model with a horizontal resolution of 5 km x 5 km. For this purpose, the measurements of the hourly SO₂ and O₃ concentrations available in three air quality monitoring stations in Lima, Peru were used for the purpose of validating the simulations of the SO₂ and O₃ concentrations obtained with the WRF-Chem model in February 2018. For the quantitative evaluation of the simulations of these gases, statistical techniques were implemented, such as the average of the simulations; the average of the measurements; the Mean Bias (MeB); the Mean Error (MeE); and the Root Mean Square Error (RMSE). The results of these statistical metrics indicated that the simulated SO₂ and O₃ values over-predicted the SO₂ and O₃ measurements. For the SO₂ concentration, the MeB values varied from 0.58 to 26.35 µg/m³; the MeE values varied from 8.75 to 26.5 µg/m³; the RMSE values varied from 13.3 to 31.79 µg/m³; while for O₃ concentrations the statistical values of the MeB varied from 37.52 to 56.29 µg/m³; the MeE values varied from 37.54 to 56.70 µg/m³; the RMSE values varied from 43.05 to 69.56 µg/m³. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ground-ozone" title="ground-ozone">ground-ozone</a>, <a href="https://publications.waset.org/abstracts/search?q=lima" title=" lima"> lima</a>, <a href="https://publications.waset.org/abstracts/search?q=sulphur%20dioxide" title=" sulphur dioxide"> sulphur dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=WRF-chem" title=" WRF-chem"> WRF-chem</a> </p> <a href="https://publications.waset.org/abstracts/154756/evaluating-hourly-sulphur-dioxide-and-ground-ozone-simulated-with-the-air-quality-model-in-lima-peru" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154756.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">137</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">67</span> A Proposal of Ontology about Brazilian Government Transparency Portal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Estela%20Mayra%20de%20Moura%20Vianna">Estela Mayra de Moura Vianna</a>, <a href="https://publications.waset.org/abstracts/search?q=Thiago%20Jos%C3%A9%20Tavares%20%C3%81vila"> Thiago José Tavares Ávila</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Morais%20Silva"> Bruno Morais Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Diego%20Henrique%20Bezerra"> Diego Henrique Bezerra</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulo%20Henrique%20Gomes%20Silva"> Paulo Henrique Gomes Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Pedro%20da%20Silva"> Alan Pedro da Silva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Brazilian Federal Constitution defines the access to information as a crucial right of the citizen and the Law on Access to Public Information, which regulates this right. Accordingly, the Fiscal Responsibility Act, 2000, amended in 2009 by the “Law of Transparency”, began demanding a wider disclosure of public accounts for the society, including electronic media for public access. Thus, public entities began to create "Transparency Portals," which aim to gather a diversity of data and information. However, this information, in general, is still published in formats that do not simplify understanding of the data by citizens and that could be better especially available for audit purposes. In this context, a proposal of ontology about Brazilian Transparency Portal can play a key role in how these data will be better available. This study aims to identify and implement in ontology, the data model about Transparency Portal ecosystem, with emphasis in activities that use these data for some applications, like audits, press activities, social government control, and others. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=audit" title="audit">audit</a>, <a href="https://publications.waset.org/abstracts/search?q=government%20transparency" title=" government transparency"> government transparency</a>, <a href="https://publications.waset.org/abstracts/search?q=ontology" title=" ontology"> ontology</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20sector" title=" public sector"> public sector</a> </p> <a href="https://publications.waset.org/abstracts/14657/a-proposal-of-ontology-about-brazilian-government-transparency-portal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14657.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">506</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">66</span> Assessing Student Attitudes toward Graded Readers, MReader and the MReader Challenge </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Catherine%20Cheetam">Catherine Cheetam</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Harper"> Alan Harper</a>, <a href="https://publications.waset.org/abstracts/search?q=Melody%20Elliott"> Melody Elliott</a>, <a href="https://publications.waset.org/abstracts/search?q=Mika%20Ito"> Mika Ito</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes a pilot study conducted with English as a foreign language (EFL) students at a private university in Japan who used graded readers and the MReader website in class or independently to enhance their English reading skills.

The study focused specifically on the attitudes of thirty-six EFL students who successfully completed the Challenge in the 2015 spring semester using graded readers and MReader, and their motivation to continue using English in the future. The attitudes of these students were measured using their responses to statements on a Likert scaled survey. Follow-up semi-structured interviews were conducted with eleven students to gain additional insight into their opinions. The results from this study suggest that reading graded readers in general promoted intrinsic motivation among a majority of the participants. This study is preliminary and needs to be expanded and continued to assess the lasting impact of the extensive reading program. Limitations and future directions of the study are also summarized and discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attitudes" title="attitudes">attitudes</a>, <a href="https://publications.waset.org/abstracts/search?q=extensive" title=" extensive"> extensive</a>, <a href="https://publications.waset.org/abstracts/search?q=intrinsic" title=" intrinsic"> intrinsic</a>, <a href="https://publications.waset.org/abstracts/search?q=methodolgies" title=" methodolgies"> methodolgies</a>, <a href="https://publications.waset.org/abstracts/search?q=motivation" title=" motivation"> motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=reading" title=" reading"> reading</a> </p> <a href="https://publications.waset.org/abstracts/59317/assessing-student-attitudes-toward-graded-readers-mreader-and-the-mreader-challenge" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59317.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">210</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">65</span> Pareidolia and Perception of Anger in Vehicle Styles: Survey Results</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alan%20S.%20Hoback">Alan S. Hoback</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Most people see human faces in car front and back ends because of the process of pareidolia. 96 people were surveyed to see how many of them saw a face in the vehicle styling. Participants were aged 18 to 72 years. 94% of the participants saw faces in the front-end design of production models. All participants that recognized faces indicated that most styles showed some degree of an angry expression. It was found that women were more likely to see faces in inanimate objects. However, with respect to whether women were more likely to perceive anger in the vehicle design, the results need further clarification. Survey responses were correlated to the design features of vehicles to determine what cues the respondents were likely looking at when responding. Whether the features looked anthropomorphic was key to anger perception. Features such as the headlights which could represent eyes and the air intake that could represent a mouth had high correlations to trends in scores. Results are compared among models, makers, by groupings of body styles classifications for the top 12 brands sold in the US, and by year for the top 20 models sold in the US in 2016. All of the top models sold increased in perception of an angry expression over the last 20 years or since the model was introduced, but the relative change varied by body style grouping. <p
