Of the total plant material grown, approximately 40% is considered waste and left in the field to decay. This practice allows fungal diseases such as Sigatoka Leaf Spot to develop, limiting plant growth and spreading spores in the air that can cause respiratory problems in the surrounding population. The pseudostem is considered a waste residue of production (60 to 80 tonnes/ha/year), although it is a good source of dietary fiber and volatile organic compounds (VOC’s). Strategies to process banana pseudostem into palatable, nutritious and marketable food materials could provide significant social and economic benefits. Extraction of VOC’s with desirable odor from dried and fresh pseudostem could improve the smell of products from the confectionary and bakery industries. Incorporation of banana pseudostem flour into bakery products could provide cost savings and improve nutritional value. The aim of this study was to determine the effects of drying methods and different banana species on the profile of volatile aroma compounds in dried banana pseudostem. The banana species analyzed were Musa acuminata and Musa balbisiana. Fresh banana pseudostem samples were processed by either freeze-drying (FD) or heat pump drying (HPD). The extraction of VOC’s was performed at ambient temperature using vacuum distillation and the resulting, mostly aqueous, distillates were analyzed using headspace solid phase microextraction (SPME) gas chromatography – mass spectrometry (GC-MS). Optimal SPME adsorption conditions were 50 °C for 60 min using a Supelco 65 μm PDMS/DVB Stableflex fiber1. Compounds were identified by comparison of their electron impact mass spectra with those from the Wiley 9 / NIST 2011 combined mass spectral library. The results showed that the two species have notably different VOC profiles. Both species contained VOC’s that have been established in literature to have pleasant appetizing aromas. These included l-Menthone, D-Limonene, trans-linlool oxide, 1-Nonanol, CIS 6 Nonen-1ol, 2,6 Nonadien-1-ol, Benzenemethanol, 4-methyl, 1-Butanol, 3-methyl, hexanal, 1-Propanol, 2-methyl- acid، 2-Methyl-2-butanol. Results show banana pseudostem VOC’s are better preserved by FD than by HPD. This study is still in progress and should lead to the optimization of processing techniques that would promote the utilization of banana pseudostem in the food industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20pump%20drying" title="heat pump drying">heat pump drying</a>, <a href="https://publications.waset.org/abstracts/search?q=freeze%20drying" title=" freeze drying"> freeze drying</a>, <a href="https://publications.waset.org/abstracts/search?q=SPME" title=" SPME"> SPME</a>, <a href="https://publications.waset.org/abstracts/search?q=vacuum%20distillation" title=" vacuum distillation"> vacuum distillation</a>, <a href="https://publications.waset.org/abstracts/search?q=VOC%20analysis" title=" VOC analysis"> VOC analysis</a> </p> <a href="https://publications.waset.org/abstracts/56309/effects-of-drying-and-extraction-techniques-on-the-profile-of-volatile-compounds-in-banana-pseudostem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56309.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">335</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">215</span> Umm Arrazam, Libyan Driling Fluid Resistivity Evaluation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omar%20Hussein%20El%20Ayadi">Omar Hussein El Ayadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Mustafa%20Alkekly"> Ali Mustafa Alkekly</a>, <a href="https://publications.waset.org/abstracts/search?q=Nader%20Ahmad%20Musa"> Nader Ahmad Musa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Search and evaluate locale source of raw material which can be used as drilling fluid is one of most important economical target.

Furthermore, desirability is also influencing feasibility. Therefore, desirability and feasibility may also play their role as double mediators in the relationship between entrepreneurial education and passion. The role of gender has become very vital in entrepreneurship studies. Therefore, we also incorporated the role of gender as a moderator while studying the indirect effect of entrepreneurial education on entrepreneurial passion via desirability and feasibility. We proposed that entrepreneurial education may influence the passion of male individuals primarily through feasibility. On the other hand, entrepreneurial education may impact on the entrepreneurial passion of female individuals primarily through the mediation of desirability. Learning orientation may increase the direct effect of entrepreneurial education on entrepreneurial passion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entrepreneurial%20passion" title="entrepreneurial passion">entrepreneurial passion</a>, <a href="https://publications.waset.org/abstracts/search?q=perceived%20desirability" title=" perceived desirability"> perceived desirability</a>, <a href="https://publications.waset.org/abstracts/search?q=perceived%20feasibility" title=" perceived feasibility"> perceived feasibility</a>, <a href="https://publications.waset.org/abstracts/search?q=entrepreneurial%20intention" title=" entrepreneurial intention"> entrepreneurial intention</a> </p> <a href="https://publications.waset.org/abstracts/158581/the-role-of-entrepreneurship-education-in-developing-the-entrepreneurial-passion-a-gender-comparative-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158581.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">114</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">212</span> Impact of Machining Parameters on the Surface Roughness of Machined PU Block</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Louis%20Denis%20Kevin%20Catherine">Louis Denis Kevin Catherine</a>, <a href="https://publications.waset.org/abstracts/search?q=Raja%20Aziz%20Raja%20Ma%E2%80%99arof"> Raja Aziz Raja Ma’arof</a>, <a href="https://publications.waset.org/abstracts/search?q=Azrina%20Arshad"> Azrina Arshad</a>, <a href="https://publications.waset.org/abstracts/search?q=Sangeeth%20Suresh"> Sangeeth Suresh </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Machining parameters are very important in determining the surface quality of any material. In the past decade, some new engineering materials were developed for the manufacturing industry which created a need to conduct an investigation on the impact of the said parameters on their surface roughness. The polyurethane (PU) block is widely used in the automotive industry to manufacture parts such as checking fixtures that are used to verify the dimensional accuracy of automotive parts. In this paper, the design of experiment (DOE) was used to investigate the effect of the milling parameters on the PU block. Furthermore, an analysis of the machined surface chemical composition was done using scanning electron microscope (SEM). It was found that the surface roughness of the PU block is severely affected when PU undergoes a flood machining process instead of a dry condition. In addition, the step over and the silicon content were found to be the most significant parameters that influence the surface quality of the PU block. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polyurethane%20%28PU%29" title="polyurethane (PU)">polyurethane (PU)</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20of%20experiment%20%28DOE%29" title=" design of experiment (DOE)"> design of experiment (DOE)</a>, <a href="https://publications.waset.org/abstracts/search?q=scanning%20electron%20microscope%20%28SEM%29" title=" scanning electron microscope (SEM)"> scanning electron microscope (SEM)</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20roughness" title=" surface roughness"> surface roughness</a> </p> <a href="https://publications.waset.org/abstracts/20483/impact-of-machining-parameters-on-the-surface-roughness-of-machined-pu-block" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20483.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">521</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">211</span> River's Bed Level Changing Pattern Due to Sedimentation, Case Study: Gash River, Kassala, Sudan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Faisal%20Ali">Faisal Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasssan%20Saad%20Mohammed%20Hilmi"> Hasssan Saad Mohammed Hilmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Mohamed"> Mustafa Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Shamseddin%20Musa"> Shamseddin Musa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Gash rivers an ephemeral river, it usually flows from July to September, it has a braided pattern with high sediment content, of 15200 ppm in suspension, and 360 kg/sec as bed load.

The process sensor generates output voltages in the range of 401 mV (fast-fast corner) to 443 mV (slow-slow corner) at nominal condition. The power dissipation for this process sensor is 6.3 µW with a supply voltage of 1.8V with a silicon area of 190 µm X 60 µm.

However, the overactivation of astrocytes and microglia due to lead toxicity produce excessive pro-inflammatory cytokines, mediating neurodegenerative diseases. The present study investigated the mitigatory effects of quercetin on neuroinflammation, correlating with memory function in lead-exposed rats. In this study, Wistar rats were administered orally with Quercetin (Q: 60 mg/kg) and Succimer as a standard drug (S: 10 mg/kg) for 21 days after lead exposure (Pb: 125 mg/kg) of 21 days or in combination with Pb, once daily for 42 days. Working and reference memory was assessed using an Eight-arm radial water maze (8-ARWM). The changes in brain lead level, the neuronal nitric oxide synthase (nNOS) activity, and the level of neuroinflammatory markers such as tumour necrosis factor-alpha (TNF-α) and Interleukin 1 Beta (IL-1β) were determined. Immunohistochemically, astrocyte expression was evaluated. The results showed that the brain level of lead was increased significantly in lead-exposed rats. The expression of astrocytes increased in the CA3 and CA1 regions of the hippocampus, and the levels of brain TNF-α and IL-1β increased in lead-exposed rats. Lead impaired reference and working memory by increasing reference memory errors and working memory incorrect errors in lead-exposed rats. However, quercetin treatment effectively improved memory and inhibited neuroinflammation by reducing astrocytes’ expression and the levels of TNF-α and IL-1β. The expression of astrocytes and the levels of TNF-α and IL-1β correlated with memory function. The possible explanation for quercetin’s anti-neuroinflammatory effect is that it modulates the activity of cellular proteins involved in the inflammatory response; inhibits the transcription factor of nuclear factor-kappa B (NF-κB), which regulates the expression of proinflammatory molecules; inhibits kinases required for the synthesis of Glial fibrillary acidic protein (GFAP) and modifies the phosphorylation of some proteins, which affect the structure and function of intermediate filament proteins; and, lastly, induces Cyclic-AMP Response Element Binding (CREB) activation and neurogenesis as a compensatory mechanism for memory deficits and neuronal cell death. In conclusion, the levels of neuroinflammatory markers negatively correlated with memory function. Thus, quercetin may be a promising therapy in neuroinflammation and memory dysfunction in populations prone to lead exposure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lead" title="lead">lead</a>, <a href="https://publications.waset.org/abstracts/search?q=quercetin" title=" quercetin"> quercetin</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroinflammation" title=" neuroinflammation"> neuroinflammation</a>, <a href="https://publications.waset.org/abstracts/search?q=memory" title=" memory"> memory</a> </p> <a href="https://publications.waset.org/abstracts/185197/the-mitigation-of-quercetin-on-lead-induced-neuroinflammation-in-a-rat-model-changes-in-neuroinflammatory-markers-and-memory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185197.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">54</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">207</span> Behavior of a Vertical Pile under the Effect of an Inclined Load</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fathi%20Mohamed%20Abdrabbo">Fathi Mohamed Abdrabbo</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Elsayed%20Gaaver"> Khaled Elsayed Gaaver</a>, <a href="https://publications.waset.org/abstracts/search?q=Musab%20Musa%20Eldooma"> Musab Musa Eldooma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an attempt made to investigate the behavior of a single vertical steel hollow pile embedded in sand subjected to compressive inclined load at various inclination angles α through FEM package MIDAS GTS/NX 2019.

The paper uses the qualitative approach and relevance theory by Sperber and Wilson (1995) to highlight and examine DMs in different communicative contexts. In the course of data collection, five (5) academic staff from the five faculties of the university who are already Facebook friends of the researcher are used as the participants with their consent. The paper examines the communicative functions of English DMs among UMYUK academic staff on Facebook and reveals a number of communicative functions used in different contexts. One of the major findings indicates that 'contrastive markers' such as 'but', 'however', 'although' etc. are the dominant communicative functions employed by UMYUK academic staff on Facebook with 42% occurrence; it also shows that a single DM can function differently in the same linguistic environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=role" title="role">role</a>, <a href="https://publications.waset.org/abstracts/search?q=communicative" title=" communicative"> communicative</a>, <a href="https://publications.waset.org/abstracts/search?q=discourse%20markers" title=" discourse markers"> discourse markers</a>, <a href="https://publications.waset.org/abstracts/search?q=facebook" title=" facebook"> facebook</a>, <a href="https://publications.waset.org/abstracts/search?q=academic%20staff" title=" academic staff"> academic staff</a> </p> <a href="https://publications.waset.org/abstracts/131862/communicative-roles-of-english-discourse-markers-on-facebook-among-umaru-musa-yaradua-university-members-of-academic-staff" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131862.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">169</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">204</span> Performance Evaluation of Moringa Oleifera as Coagulant for Treating Abattoir Wastewater</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adesiji%20Adeolu%20Richard">Adesiji Adeolu Richard</a>, <a href="https://publications.waset.org/abstracts/search?q=Hassa%20Musa"> Hassa Musa</a>, <a href="https://publications.waset.org/abstracts/search?q=Osita%20Evaritus%20Asogwa"> Osita Evaritus Asogwa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mary%20Oluwatobi%20Odekunle"> Mary Oluwatobi Odekunle</a>, <a href="https://publications.waset.org/abstracts/search?q=Mangey%20Jarumi%20Akila"> Mangey Jarumi Akila</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, extract from raw Moringa Oleifera seeds for the treatment of 40 liters of abattoir wastewater was studied for a period of ten (10) weeks.

The results generally showed that 16g/500ml of Moringa Oleifera was able to treat abattoir wastewater after weeks of the experiment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Moringa%20Oleifera" title="Moringa Oleifera">Moringa Oleifera</a>, <a href="https://publications.waset.org/abstracts/search?q=abattoir%20wastewater" title=" abattoir wastewater"> abattoir wastewater</a>, <a href="https://publications.waset.org/abstracts/search?q=turbidity" title=" turbidity"> turbidity</a>, <a href="https://publications.waset.org/abstracts/search?q=conductivity" title=" conductivity"> conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=pH" title=" pH"> pH</a> </p> <a href="https://publications.waset.org/abstracts/160820/performance-evaluation-of-moringa-oleifera-as-coagulant-for-treating-abattoir-wastewater" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160820.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">120</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">203</span> Learning and Practicing Assessment in a Pre-Service Teacher Education Program: Comparative Perspective of UK and Pakistani Universities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Malik%20Ghulam%20Behlol">Malik Ghulam Behlol</a>, <a href="https://publications.waset.org/abstracts/search?q=Alison%20Fox"> Alison Fox</a>, <a href="https://publications.waset.org/abstracts/search?q=Faiza%20Masood"> Faiza Masood</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabiha%20Arshad"> Sabiha Arshad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper explores the barriers to the application of learning-supportive assessment at teaching practicum while investigating the role of university teachers (UT), cooperative teachers (CT), prospective teachers ( PT) and heads of the practicum schools (HPS) in the selected universities of Pakistan and the UK. It is a qualitative case study and data were collected through the lesson observation of UT in the pre-service teacher education setting and PT in practicum schools. Interviews with UT, HPS, and Focus Group Discussions with PT were conducted too. The study has concluded that as compared to the UK counterpart, PT in Pakistan faces significant barriers in applying learning-supportive assessment in the school practicum settings because of large class sizes, lack of institutionalised collaboration between universities and schools, poor modelling of the lesson, ineffective feedback practices, lower order thinking assignments, and limited opportunities to use technology in school settings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assessment" title="assessment">assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-service%20teacher%20education" title=" pre-service teacher education"> pre-service teacher education</a>, <a href="https://publications.waset.org/abstracts/search?q=theory-practice%20gap" title=" theory-practice gap"> theory-practice gap</a>, <a href="https://publications.waset.org/abstracts/search?q=teacher%20education" title=" teacher education"> teacher education</a> </p> <a href="https://publications.waset.org/abstracts/160315/learning-and-practicing-assessment-in-a-pre-service-teacher-education-program-comparative-perspective-of-uk-and-pakistani-universities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160315.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">123</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">202</span> Social Construction of Gender: Comparison of Gender Stereotypes among Bureaucrats and Non- Bureaucrats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arshad%20Ali">Arshad Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims to highlight the comparative patterns of social construction of gender among bureaucrats and non-bureaucrats. For the purpose of this study purposive sample of 8 respondents, including both male and female bureaucrats and non-bureaucrats, was collected from Gujranwala and Lahore. The measures for collecting data included an indigenous demographic information sheet and interview protocol related to gender roles, social construction of gender and managerial performance. The collected data was analyzed through the Nvivo version 11 and analysis reveals that there are diverse perceptions regarding male and female stereotyping among bureaucrats and non-bureaucrats, as different kinds of social environments lead to the modification of stereotypes. The research contributes to gender studies, specifically in the context of Pakistani society. There are very few studies available, and empirical data about Gender construction is scanty, so the study provides an impetus for future research. It is suggested that future research explore the phenomenon at a larger scale, including more respondents and another dimension, by keeping in view the socio-economic factors and policies of the government regarding the elimination of gender discrimination in Pakistan. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20construction" title="social construction">social construction</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a>, <a href="https://publications.waset.org/abstracts/search?q=bureaucrats" title=" bureaucrats"> bureaucrats</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20perception" title=" gender perception"> gender perception</a> </p> <a href="https://publications.waset.org/abstracts/175162/social-construction-of-gender-comparison-of-gender-stereotypes-among-bureaucrats-and-non-bureaucrats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175162.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">75</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">201</span> Challenges of Teaching and Learning English Speech Sounds in Five Selected Secondary Schools in Bauchi, Bauchi State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mairo%20Musa%20Galadima">Mairo Musa Galadima</a>, <a href="https://publications.waset.org/abstracts/search?q=Phoebe%20Mshelia"> Phoebe Mshelia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Nigeria, the national policy of education stipulates that the kindergarten primary schools and the legislature are to use the three popular Nigerian Languages namely: Hausa, Igbo and Yoruba.

The same procedure was performed on the rest of the samples and austempered at 270oC, 290oC, 310oC and 330oC. Next, mechanical properties’ tests conducted. The austempered samples were then analyzed for microstructure using scanning electron microscope (SEM). The results indicate that tensile strength and hardness dip with increase in the temperature. Again, impact strength improved with rise in the temperature. It was observed that 270oC is the best austempering temperature, since it produces austempered sample with the best combination of mechanical properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epoxidized%20transesterified%20cotton%20seed%20oil" title="epoxidized transesterified cotton seed oil">epoxidized transesterified cotton seed oil</a>, <a href="https://publications.waset.org/abstracts/search?q=austempering%20temperature" title=" austempering temperature"> austempering temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20carbon%20steel" title=" high carbon steel"> high carbon steel</a>, <a href="https://publications.waset.org/abstracts/search?q=bainitic%20structure" title=" bainitic structure"> bainitic structure</a> </p> <a href="https://publications.waset.org/abstracts/187597/temperature-depended-austempering-of-high-carbon-steel-using-epoxidized-transesterified-cotton-seed-oil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187597.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">46</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">198</span> Seismic Inversion to Improve the Reservoir Characterization: Case Study in Central Blue Nile Basin, Sudan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Safwat%20E.%20Musa">Safwat E.

These crossplots were successful to discriminate between sand and shale when using P-Impedance values, and between the wet sand and the pay sand when using both P-impedance and Vp/Vs together. Also, some impedance sections were converted to porosity sections using linear formula to characterize the reservoir in terms of porosity. The used crossplots were created on log resolution, while the seismic resolution can identify only the reservoir, unless a 3D seismic angle stacks were available; then it would be easier to identify the pay sand with great confidence; through high resolution seismic inversion and geostatistical approach when using P-impedance and Vp/Vs volumes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=basin" title="basin">basin</a>, <a href="https://publications.waset.org/abstracts/search?q=Blue%20Nile" title=" Blue Nile"> Blue Nile</a>, <a href="https://publications.waset.org/abstracts/search?q=inversion" title=" inversion"> inversion</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic" title=" seismic"> seismic</a> </p> <a href="https://publications.waset.org/abstracts/19111/seismic-inversion-to-improve-the-reservoir-characterization-case-study-in-central-blue-nile-basin-sudan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19111.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">197</span> Challenges of Teaching and Learning English Speech Sounds in Five Selected Secondary Schools in Bauchi, Bauchi State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mairo%20Musa%20Galadima">Mairo Musa Galadima</a>, <a href="https://publications.waset.org/abstracts/search?q=Phoebe%20Mshelia"> Phoebe Mshelia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Nigeria, the national policy of education stipulates that the kindergarten-primary schools and the legislature are to use the three popular Nigerian Languages namely: Hausa, Igbo, and Yoruba.

Chelating agents enhance the availability of Cd, which is the main factor in the phytoremediation. This study was conducted to assessed the potential of two Pelargonium species (Pelargonium zonale, Pelargonium hortorum) in EDTA enhanced phytoextraction of Cd using pot experiment. Different doses of EDTA (0, 1, 2, 3, 4, 5 mmol kg-1) was used, and results showed that there was significant increase (approximately 2.1 folds) in the mobility of Cd at EDTA 5 mg kg-1 as compared to control. Both plants have TF and BCF more than 1 and have potential for the phytoextraction of Cd. However, the Pelargonium hortorum showed higher biomass and Cd uptake as compared to Pleragonium zonale. The maximum Cd accumulation in shoot and root of Pelargonium zonale was 484.4 and 264.41 mg kg-1 respectively at 2 mmol kg-1. However, the Pelargonium hortorum accumulate 996.9 and 350 mg kg-1 of Cd in shoot and root respectively at 4 mmol kg-1. Pelargonium hortorum uptake approximately 10.7 folds higher Cd concentration as compared to the Pelargonium zonale. Results revealed that P. hortorum performed better than P. zonal even at higher Cd and EDTA doses however toxicity and leaching potential of increased Cd and EDTA concentrations needs to be explored before field application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cadmium" title="Cadmium">Cadmium</a>, <a href="https://publications.waset.org/abstracts/search?q=EDTA" title=" EDTA"> EDTA</a>, <a href="https://publications.waset.org/abstracts/search?q=Pelargonium" title=" Pelargonium"> Pelargonium</a>, <a href="https://publications.waset.org/abstracts/search?q=phytoextraction" title=" phytoextraction"> phytoextraction</a> </p> <a href="https://publications.waset.org/abstracts/70604/potential-of-two-pelargonium-species-for-edta-assisted-phytoextraction-of-cadmium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70604.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">300</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">195</span> A New Study on Mathematical Modelling of COVID-19 with Caputo Fractional Derivative</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sadia%20Arshad">Sadia Arshad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The new coronavirus disease or COVID-19 still poses an alarming situation around the world. Modeling based on the derivative of fractional order is relatively important to capture real-world problems and to analyze the realistic situation of the proposed model. Weproposed a mathematical model for the investigation of COVID-19 dynamics in a generalized fractional framework. The new model is formulated in the Caputo sense and employs a nonlinear time-varying transmission rate. The existence and uniqueness solutions of the fractional order derivative have been studied using the fixed-point theory. The associated dynamical behaviors are discussed in terms of equilibrium, stability, and basic reproduction number. For the purpose of numerical implementation, an effcient approximation scheme is also employed to solve the fractional COVID-19 model. Numerical simulations are reported for various fractional orders, and simulation results are compared with a real case of COVID-19 pandemic.

In this research, the asphalt mixture was modified with carbon nanotubes ranging from 0.2% to 2% of binder to study the effect of CNT modification on rutting potential and fatigue life of asphalt mixtures. During this study, the conventional and modified asphalt mixture was subjected to a uni-axial dynamic creep test and dry Hamburg wheel tracking test to study rutting resistance. Fatigue behavior of asphalt mixture was studied using a four-point bending test apparatus. The plateau value of asphalt mixture was taken as a measure of fatigue performance according to the ratio of dissipated energy approach. Results of these experiments showed that CNT modified asphalt mixtures had reduced rut depth and increased rutting and fatigue resistance at higher percentages of carbon nanotubes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanotubes" title="carbon nanotubes">carbon nanotubes</a>, <a href="https://publications.waset.org/abstracts/search?q=fatigue" title=" fatigue"> fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=four%20point%20bending%20test" title=" four point bending test"> four point bending test</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20asphalt" title=" modified asphalt"> modified asphalt</a>, <a href="https://publications.waset.org/abstracts/search?q=rutting" title=" rutting"> rutting</a> </p> <a href="https://publications.waset.org/abstracts/107538/laboratory-evaluation-of-rutting-and-fatigue-damage-resistance-of-asphalt-mixtures-modified-with-carbon-nano-tubes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107538.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">145</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">192</span> Effect of Chemical Treatment on Mechanical Properties of KENAF Fiber Reinforced Unsaturated Polyester Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20S.%20Abdullahi">S.

Hand lay-up technique was used with dump-bell shaped mold. The kenaf bast fiber was retted enzymatically, washed, dried and combed with a nylon brush. A portion of the kenaf fiber was mercerized and treated with benzoylchloride prior to composite fabrication. Untreated kenaf fiber was also used to prepare the composites to serve as control. The cured composites were subjected to various mechanical testes, such as hardness test, impact test and tensile strength test. The results obtained indicated an increase in all the parameters tested with the fiber treatment. This is because the lignin, hemi-celluloses, pectin and other impurities were removed during alkaline treatment (i.e mercerization). This shows that, the durability of the natural cellulosic fibers to different composite applications can be achieved via fiber treatments. <p class="card-text"><strong>Keywords:</strong> <a
