Although the overwhelming advantages of ATM cannot be over-emphasized, its alarming fraud rate has become a bottleneck in it’s full adoption in Nigeria. This study examined the menace of ATM in the society another cost of running ATM services by banks in the country. The researcher developed a prototype of an enhanced Automated Teller Machine Authentication using Short Message Service (SMS) Verification. The developed prototype was tested by Ten (10) respondents who are users of ATM cards in the country and the data collected was analyzed using Statistical Package for Social Science (SPSS). Based on the results of the analysis, it is being envisaged that the developed prototype will go a long way in reducing the alarming rate of ATM fraud in Nigeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ATM" title="ATM">ATM</a>, <a href="https://publications.waset.org/abstracts/search?q=ATM%20fraud" title=" ATM fraud"> ATM fraud</a>, <a href="https://publications.waset.org/abstracts/search?q=e-banking" title=" e-banking"> e-banking</a>, <a href="https://publications.waset.org/abstracts/search?q=prototyping" title=" prototyping"> prototyping</a> </p> <a href="https://publications.waset.org/abstracts/2158/enhanced-automated-teller-machine-using-short-message-service-authentication-verification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2158.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">322</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">76</span> IoT Based Information Processing and Computing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mannan%20Ahmad%20Rasheed">Mannan Ahmad Rasheed</a>, <a href="https://publications.waset.org/abstracts/search?q=Sawera%20Kanwal"> Sawera Kanwal</a>, <a href="https://publications.waset.org/abstracts/search?q=Mansoor%20Ahmad%20Rasheed"> Mansoor Ahmad Rasheed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Internet of Things (IoT) has revolutionized the way we collect and process information, making it possible to gather data from a wide range of connected devices and sensors. This has led to the development of IoT-based information processing and computing systems that are capable of handling large amounts of data in real time. This paper provides a comprehensive overview of the current state of IoT-based information processing and computing, as well as the key challenges and gaps that need to be addressed. This paper discusses the potential benefits of IoT-based information processing and computing, such as improved efficiency, enhanced decision-making, and cost savings. Despite the numerous benefits of IoT-based information processing and computing, several challenges need to be addressed to realize the full potential of these systems. These challenges include security and privacy concerns, interoperability issues, scalability and reliability of IoT devices, and the need for standardization and regulation of IoT technologies. Moreover, this paper identifies several gaps in the current research related to IoT-based information processing and computing. One major gap is the lack of a comprehensive framework for designing and implementing IoT-based information processing and computing systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=IoT" title="IoT">IoT</a>, <a href="https://publications.waset.org/abstracts/search?q=computing" title=" computing"> computing</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20processing" title=" information processing"> information processing</a>, <a href="https://publications.waset.org/abstracts/search?q=Iot%20computing" title=" Iot computing"> Iot computing</a> </p> <a href="https://publications.waset.org/abstracts/165683/iot-based-information-processing-and-computing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165683.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">188</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> Determination and Distribution of Formation Thickness Using Seismic and Well Data in Baga/Lake Sub-basin, Chad Basin Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gabriel%20Efomeh%20Omolaiye">Gabriel Efomeh Omolaiye</a>, <a href="https://publications.waset.org/abstracts/search?q=Olatunji%20Seminu"> Olatunji Seminu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jimoh%20Ajadi"> Jimoh Ajadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Ayoola%20Jimoh"> Yusuf Ayoola Jimoh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Nigerian part of the Chad Basin till date has been one of the few critically studied basins, with few published scholarly works, compared to other basins such as Niger Delta, Dahomey, etc. This work was undertaken by the integration of 3D seismic interpretations and the well data analysis of eight wells fairly distributed in block A, Baga/Lake sub-basin in Borno basin with the aim of determining the thickness of Chad, Kerri-Kerri, Fika, and Gongila Formations in the sub-basin. Da-1 well (type-well) used in this study was subdivided into stratigraphic units based on the regional stratigraphic subdivision of the Chad basin and was later correlated with other wells using similarity of observed log responses. The combined density and sonic logs were used to generate synthetic seismograms for seismic to well ties. Five horizons were mapped, representing the tops of the formations on the 3D seismic data covering the block; average velocity function with maximum error/residual of 0.48% was adopted in the time to depth conversion of all the generated maps. There is a general thickening of sediments from the west to the east, and the estimated thicknesses of the various formations in the Baga/Lake sub-basin are Chad Formation (400-750 m), Kerri-Kerri Formation (300-1200 m), Fika Formation (300-2200 m) and Gongila Formation (100-1300 m). The thickness of the Bima Formation could not be established because the deepest well (Da-1) terminates within the formation. This is a modification to the previous and widely referenced studies of over forty decades that based the estimation of formation thickness within the study area on the observed outcrops at different locations and the use of few well data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Baga%2FLake%20sub-basin" title="Baga/Lake sub-basin">Baga/Lake sub-basin</a>, <a href="https://publications.waset.org/abstracts/search?q=Chad%20basin" title=" Chad basin"> Chad basin</a>, <a href="https://publications.waset.org/abstracts/search?q=formation%20thickness" title=" formation thickness"> formation thickness</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic" title=" seismic"> seismic</a>, <a href="https://publications.waset.org/abstracts/search?q=velocity" title=" velocity"> velocity</a> </p> <a href="https://publications.waset.org/abstracts/135598/determination-and-distribution-of-formation-thickness-using-seismic-and-well-data-in-bagalake-sub-basin-chad-basin-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135598.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">185</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">74</span> Investigation into the Possibility of Using Recycled Polyethelene to Replace Natural Rubber in the Production of Different Products</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Otokiti%20Mojeed%20Jimoh">Otokiti Mojeed Jimoh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work investigates the possibility of using recycled polyethylene LDPE as a base polymer in production of different products (shoe sole, foot mat, and many more) using carbon black as a filler to improve its mechanical properties, like hardness, tensile stress properties and elongation at break properties, from the result so far gotten there is a possibility that there is an increase in the mechanical properties of the sample compare to natural rubber sample. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=recycled%20polyethylene" title="recycled polyethylene">recycled polyethylene</a>, <a href="https://publications.waset.org/abstracts/search?q=base%20polymer" title=" base polymer"> base polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=hardness" title=" hardness"> hardness</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20properties" title=" stress properties"> stress properties</a> </p> <a href="https://publications.waset.org/abstracts/18603/investigation-into-the-possibility-of-using-recycled-polyethelene-to-replace-natural-rubber-in-the-production-of-different-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18603.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">418</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> Characterization of Petrophysical Properties of Reservoirs in Bima Formation, Northeastern Nigeria: Implication for Hydrocarbon Exploration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gabriel%20Efomeh%20Omolaiye">Gabriel Efomeh Omolaiye</a>, <a href="https://publications.waset.org/abstracts/search?q=Jimoh%20Ajadi"> Jimoh Ajadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Olatunji%20Seminu"> Olatunji Seminu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Ayoola%20Jimoh"> Yusuf Ayoola Jimoh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ubulom%20Daniel"> Ubulom Daniel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Identification and characterization of petrophysical properties of reservoirs in the Bima Formation were undertaken to understand their spatial distribution and impacts on hydrocarbon saturation in the highly heterolithic siliciclastic sequence. The study was carried out using nine well logs from Maiduguri and Baga/Lake sub-basins within the Borno Basin. The different log curves were combined to decipher the lithological heterogeneity of the serrated sand facies and to aid the geologic correlation of sand bodies within the sub-basins. Evaluation of the formation reveals largely undifferentiated to highly serrated and lenticular sand bodies from which twelve reservoirs named Bima Sand-1 to Bima Sand-12 were identified. The reservoir sand bodies are bifurcated by shale beds, which reduced their thicknesses variably from 0.61 to 6.1 m. The shale content in the sand bodies ranged from 11.00% (relatively clean) to high shale content of 88.00%. The formation also has variable porosity values, with calculated total porosity ranged as low as 10.00% to as high as 35.00%. Similarly, effective porosity values spanned between 2.00 to 24.00%. The irregular porosity values also accounted for a wide range of field average permeability estimates computed for the formation, which measured between 0.03 to 319.49 mD. Hydrocarbon saturation (Sh) in the thin lenticular sand bodies also varied from 40.00 to 78.00%. Hydrocarbon was encountered in three intervals in Ga-1, four intervals in Da-1, two intervals in Ar-1, and one interval in Ye-1. Ga-1 well encountered 30.78 m thick of hydrocarbon column in 14 thin sand lobes in Bima Sand-1, with thicknesses from 0.60 m to 5.80 m and average saturation of 51.00%, while Bima Sand-2 intercepted 45.11 m thick of hydrocarbon column in 12 thin sand lobes with an average saturation of 61.00% and Bima Sand-9 has 6.30 m column in 4 thin sand lobes. Da-1 has hydrocarbon in Bima Sand-8 (5.30 m, Sh of 58.00% in 5 sand lobes), Bima Sand-10 (13.50 m, Sh of 52.00% in 6 sand lobes), Bima Sand-11 (6.20 m, Sh of 58.00% in 2 sand lobes) and Bima Sand-12 (16.50 m, Sh of 66% in 6 sand lobes). In the Ar-1 well, hydrocarbon occurs in Bima Sand-3 (2.40 m column, Sh of 48% in a sand lobe) and Bima Sand-9 (6.0 m, Sh of 58% in a sand lobe). Ye-1 well only intersected 0.5 m hydrocarbon in Bima Sand-1 with 78% saturation. Although Bima Formation has variable saturation of hydrocarbon, mainly gas in Maiduguri, and Baga/Lake sub-basins of the research area, its highly thin serrated sand beds, coupled with very low effective porosity and permeability in part, would pose a significant exploitation challenge. The sediments were deposited in a fluvio-lacustrine environment, resulting in a very thinly laminated or serrated alternation of sand and shale beds lithofacies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bima" title="Bima">Bima</a>, <a href="https://publications.waset.org/abstracts/search?q=Chad%20Basin" title=" Chad Basin"> Chad Basin</a>, <a href="https://publications.waset.org/abstracts/search?q=fluvio-lacustrine" title=" fluvio-lacustrine"> fluvio-lacustrine</a>, <a href="https://publications.waset.org/abstracts/search?q=lithofacies" title=" lithofacies"> lithofacies</a>, <a href="https://publications.waset.org/abstracts/search?q=serrated%20sand" title=" serrated sand"> serrated sand</a> </p> <a href="https://publications.waset.org/abstracts/135605/characterization-of-petrophysical-properties-of-reservoirs-in-bima-formation-northeastern-nigeria-implication-for-hydrocarbon-exploration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135605.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">171</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">72</span> Science Education in Nigeria: Issues and Challenges</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ogbeta%20I.%20Joseph">Ogbeta I.

Two dimensionless binding quantities BEN and BEC were used in assessing the influence of binder type on two mechanical properties, Tensile Strength (TS) and Brittle Fracture Index (BFI). The two quantities were also used to assess the influence of relative density and binder concentration on TS and BFI as well as compare Binding Efficiencies (BE). The result shows that TS is dependent on relative density, binder type and binder concentration while BFI is dependent on the binder type and binder concentration; and that although, the inclusion of NMG in a paracetamol tablet formulation may not enhance the TS of the tablets produced, however it will decrease the tendency of the tablets to cap or laminate. This work concludes that BEN may be useful in quantitative assessment while BEC may be appropriate for qualitative assessment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=binding%20efficiency" title="binding efficiency">binding efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=brittle%20fracture%20index" title=" brittle fracture index"> brittle fracture index</a>, <a href="https://publications.waset.org/abstracts/search?q=dimensionless%20binding" title=" dimensionless binding"> dimensionless binding</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20strength" title=" tensile strength"> tensile strength</a> </p> <a href="https://publications.waset.org/abstracts/2503/dimensionless-binding-values-in-the-evaluation-of-paracetamol-tablet-formulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2503.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">253</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">69</span> Labour-saving Construction Using Buildability Framework through Strengthening Designers in Delivering More Buildable Designs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Lawal%20A.">Muhammad Lawal A.</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdullateef%20Abdulkarim%20Jimoh"> Abdullateef Abdulkarim Jimoh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is to appraise the labour-saving construction methods achievable using a buildability framework through an improved design system.

Owu waterfall located at Isin Local Government, Kwara state, Nigeria is the highest waterfall in the West African region, yet none of its potential usefulness has been fully exploited. Water samples were taken from two sections of the fall and were analyzed for various water quality parameters. The results obtained include pH (6.71 ± 0.1), Biochemical oxygen demand (4.2 ± 0.5 mg/l), Chemical oxygen demand (3.07 ± 0.01 mg/l), Dissolved oxygen (6.59 ± 0.6 mg/l), Turbidity (4.43 ± 0.11 NTU), Total dissolved solids (8.2 ± 0.09 mg/l), Total suspended solids (18.25 ± 0.5 mg/l), Chloride ion (0.48 ± 0.08 mg/l), Calcium ion (0.82 ± 0.02 mg/l)), Magnesium ion (0.63 ± 0.03 mg/l) and Nitrate ion (1.25 ± 0.01 mg/l). The results were compared to the World Health Organisations standard for drinking water and the Nigerian standard for drinking water. From the comparison, it can be deduced that due to the Biochemical oxygen demand value, the water is not suitable for drinking unless it undergoes treatment. However, it is suitable for other classes of water usage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Owu%20falls" title="Owu falls">Owu falls</a>, <a href="https://publications.waset.org/abstracts/search?q=waterfall" title=" waterfall"> waterfall</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality"> water quality</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality%20parameters" title=" water quality parameters"> water quality parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20use" title=" water use"> water use</a> </p> <a href="https://publications.waset.org/abstracts/97556/water-quality-assessment-of-owu-falls-for-water-use-classification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97556.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">179</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> Q-Learning of Bee-Like Robots Through Obstacle Avoidance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jawairia%20Rasheed">Jawairia Rasheed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Modern robots are often used for search and rescue purpose.

As senior management of an organization, executives are not immune to this problem because they carry out lots of activities while on duty. This paper is centered on the benefits of Tourism, Leisure and Recreation to the management of executive stress. Executives work has always been considered to be stressful. The key objective of the research is to gain a better understanding of the causes of stress among executives and to find out how tourism, leisure, and recreational activities could be used as a means to managing stress. Interview and observation data were analyzed using SPSS. The major finding revealed that that human system has specific limitations and nature cannot be cheated. It is recommended that executives should take regular and mandatory vacation of least forty days in a year. The only answer then is rest. The research recommends that a break tends to improves and relaxes, refreshes the mind and enhances performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=executive" title="executive">executive</a>, <a href="https://publications.waset.org/abstracts/search?q=recreation" title=" recreation"> recreation</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism" title=" tourism"> tourism</a> </p> <a href="https://publications.waset.org/abstracts/51627/assessing-the-benefits-of-recreation-to-management-of-stress-among-executives-of-an-institutional-organisation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51627.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">354</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">64</span> Modeling of Compaction Curves for CCA-Cement Stabilized Lateritic Soils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20Ahmed%20Apampa">O.

This was done by first adopting an equation earlier developed for fine-grained soils and subsequent adaptation by others and extending it to modified lateritic soil through the introduction of alpha and beta parameters which are polynomial functions of the CCA binder input. The polynomial equations were determined with MATLAB R2011 curve fitting tool, while the alpha and beta parameters were determined by standard linear programming techniques using the Solver function of Microsoft Excel 2010. The model so developed was a good fit with a correlation coefficient R2 value of 0.86. The paper concludes that it is possible to determine the optimum moisture content and the maximum dry density of CCA stabilized soils from the compaction test of the unmodified soil, and recommends that this procedure is extended to other binder stabilized lateritic soils to facilitate quick decision making in roadworks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compaction" title="compaction">compaction</a>, <a href="https://publications.waset.org/abstracts/search?q=corn%20cob%20ash" title=" corn cob ash"> corn cob ash</a>, <a href="https://publications.waset.org/abstracts/search?q=lateritic%20soil" title=" lateritic soil"> lateritic soil</a>, <a href="https://publications.waset.org/abstracts/search?q=stabilization" title=" stabilization"> stabilization</a> </p> <a href="https://publications.waset.org/abstracts/22360/modeling-of-compaction-curves-for-cca-cement-stabilized-lateritic-soils" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22360.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">533</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">63</span> Fault Detection and Isolation of a Three-Tank System using Analytical Temporal Redundancy, Parity Space/Relation Based Residual Generation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20T.%20Kuda">A.

The basic idea of parity space residual generation in temporal redundancy is dynamic relationship between sensor outputs and actuator inputs (input-output model). These residuals where then used to detect whether or not the system is faulty and indicate the location of the fault when it is faulty.

Over the years, teachers of the English Language (in Nigeria) have been glued to the monotonous method of making students read comprehension passages silently and then answer the questions that follow such passages without making the reading session interactive. Hence, students often find such exercises monotonous and boring. Consequently, students' interest in language learning continues to dwindle, and this often affects their overall academic performance. Relying on Communicative Accommodation Theory therefore, the study employed the qualitative research design method to x-ray Communicative Language Teaching Approach (CLTA) in reading comprehension. Moreover, techniques such as the Genuinely Collaborative Reading Approach (GCRA), Jigsaw reading, Pre-reading, and Post-reading tasks were examined. The researcher submitted that effective reading comprehension could not be done passively. Students must respond to what they read; they must interact not only with the materials being read but also with one another and with the teacher; this can be achieved by developing communicative and interactive reading programs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collaborative%20reading%20approach" title="collaborative reading approach">collaborative reading approach</a>, <a href="https://publications.waset.org/abstracts/search?q=communicative%20teaching" title=" communicative teaching"> communicative teaching</a>, <a href="https://publications.waset.org/abstracts/search?q=interactive%20reading%20program" title=" interactive reading program"> interactive reading program</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-reading%20task" title=" pre-reading task"> pre-reading task</a>, <a href="https://publications.waset.org/abstracts/search?q=reading%20comprehension" title=" reading comprehension"> reading comprehension</a> </p> <a href="https://publications.waset.org/abstracts/158012/communicative-language-teaching-technique-a-neglected-approach-in-reading-comprehension-instruction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158012.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">106</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">59</span> Atmospheric Oxidation of Carbonyls: Insight to Mechanism, Kinetic and Thermodynamic Parameters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olumayede%20Emmanuel%20Gbenga">Olumayede Emmanuel Gbenga</a>, <a href="https://publications.waset.org/abstracts/search?q=Adeniyi%20Azeez%20Adebayo"> Adeniyi Azeez Adebayo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Carbonyls are the first-generation products from tropospheric degradation reactions of volatile organic compounds (VOCs). This computational study examined the mechanism of removal of carbonyls from the atmosphere via hydroxyl radical. The kinetics of the reactions were computed from the activation energy (using enthalpy (ΔH**) and Gibbs free energy (ΔG**). The minimum energy path (MEP) analysis reveals that in all the molecules, the products have more stable energy than the reactants, which implies that the forward reaction is more thermodynamically favorable. The hydrogen abstraction of the aromatic aldehyde, especially without methyl substituents, is more kinetically favorable compared with the other aldehydes in the order of aromatic (without methyl or meta methyl) > alkene (short chain) > diene > long-chain aldehydes. The activation energy is much lower for the forward reaction than the backward, indicating that the forward reactions are more kinetically stable than their backward reaction. In terms of thermodynamic stability, the aromatic compounds are found to be less favorable in comparison to the aliphatic. The study concludes that the chemistry of the carbonyl bond of the aldehyde changed significantly from the reactants to the products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atmospheric%20carbonyls" title="atmospheric carbonyls">atmospheric carbonyls</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidation" title=" oxidation"> oxidation</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanism" title=" mechanism"> mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetic" title=" kinetic"> kinetic</a>, <a href="https://publications.waset.org/abstracts/search?q=thermodynamic" title=" thermodynamic"> thermodynamic</a> </p> <a href="https://publications.waset.org/abstracts/184338/atmospheric-oxidation-of-carbonyls-insight-to-mechanism-kinetic-and-thermodynamic-parameters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184338.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">50</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">58</span> Technologies for Solar Energy Storage and Utilization Using Mixture of Molten Salts and Polymers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anteneh%20Mesfin%20Yeneneh">Anteneh Mesfin Yeneneh</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Shakoor"> Abdul Shakoor</a>, <a href="https://publications.waset.org/abstracts/search?q=Jimoh%20Adewole"> Jimoh Adewole</a>, <a href="https://publications.waset.org/abstracts/search?q=Safinaz%20Al%20Balushi"> Safinaz Al Balushi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Al%20Balushi"> Sara Al Balushi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The research work focuses on exploring better technologies for solar energy storage.

The Authors also investigated the potential of using different salt mixtures for better solar energy storage and better pure water productivity. Experiments were conducted to understand the impacts of solar energy collection and storage techniques on heat accumulation, heat storage capacity of various compositions of salt mixtures. Based on the experiments conducted, the economic and technical advantages of the integrated water desalination was assessed. Experiments also showed that the best salts with a higher storage efficiency of heat energy are NaCl, KNO3, and MgCl26H2O and polymers such as Poly Propylene and Poly Ethylene Terephthalate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=molten%20salts" title="molten salts">molten salts</a>, <a href="https://publications.waset.org/abstracts/search?q=desalination" title=" desalination"> desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy%20storage%20and%20utilization" title=" solar energy storage and utilization"> solar energy storage and utilization</a>, <a href="https://publications.waset.org/abstracts/search?q=polymers" title=" polymers"> polymers</a> </p> <a href="https://publications.waset.org/abstracts/128579/technologies-for-solar-energy-storage-and-utilization-using-mixture-of-molten-salts-and-polymers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128579.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">155</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">57</span> Predicting Mixing Patterns of Overflows from a Square Manhole</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Modupe%20O.%20Jimoh">Modupe O.

Understanding the pollutant transfer characteristics between manhole’s incoming sewer and the overflow is therefore of great importance. A square manhole with sides 388 mm by 388 mm and height 700 mm with an overflow facility was used in the laboratory to carry out overflow concentration measurements. Two scenarios were investigated using three flow rates. The first scenario corresponded to when the exit of the pipe becomes blocked and the only exit for the flow is the manhole. The second scenario is when there is an overflow in combination with a pipe exit. The temporal concentration measurements showed that the peak concentration of pollutants in the flow was attenuated between the inlet and the overflow. A deconvolution software was used to predict the Residence time distribution (RTD) and consequently the Cumulative Residence time distribution (CRTD). The CRTDs suggest that complete mixing is occurring between the pipe inlet and the overflow, like what is obtained in a low surcharged manhole. The results also suggest that an instantaneous stirred tank reactor model can describe the mixing characteristics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CRTDs" title="CRTDs">CRTDs</a>, <a href="https://publications.waset.org/abstracts/search?q=instantaneous%20stirred%20tank%20reactor%20model" title=" instantaneous stirred tank reactor model"> instantaneous stirred tank reactor model</a>, <a href="https://publications.waset.org/abstracts/search?q=overflow" title=" overflow"> overflow</a>, <a href="https://publications.waset.org/abstracts/search?q=square%20manholes" title=" square manholes"> square manholes</a>, <a href="https://publications.waset.org/abstracts/search?q=surcharge" title=" surcharge"> surcharge</a>, <a href="https://publications.waset.org/abstracts/search?q=temporal%20concentration%20profiles" title=" temporal concentration profiles"> temporal concentration profiles</a> </p> <a href="https://publications.waset.org/abstracts/97743/predicting-mixing-patterns-of-overflows-from-a-square-manhole" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97743.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">144</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">56</span> Patients’ Rights: An Enquiry into the Activities of Local Psychiatric Centers Managed by Muslims in South-West Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shaykh-Luqman%20Jimoh">Shaykh-Luqman Jimoh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Nigeria, aside the eight Government hospitals designated Psychiatric hospitals, there are also many local psychiatric centers managed by muslims and non-muslim individuals. These centers have been heavily criticized for human right abuses. This study is an inquiry into the truth or otherwise of the criticism. The study focuses on the activities of local centers managed by muslim individuals in South-West Nigeria with a view to determining the extent they uphold or violate their patients’ fundamental human rights as guaranteed by Islam. Information about the activities of the centers were collected through oral interviews. Both descriptive and analytical methods were used in the study. The study revealed that while there are some activities of the local centers managed by muslims in the study area that could be regarded as outright violation of patients’ fundamental human rights, some others, in view of the rationale behind them, may not necessarily constitute outright violation of the patients’ fundamental human rights as hitherto painted except where excesses are committed. The study therefore, using Islamic paradigm, suggests general measures that could be taken to improve on the activities of the centers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=local%20psychiatric%20centers" title="local psychiatric centers">local psychiatric centers</a>, <a href="https://publications.waset.org/abstracts/search?q=muslim%20exorcists" title=" muslim exorcists"> muslim exorcists</a>, <a href="https://publications.waset.org/abstracts/search?q=patients%E2%80%99%20rights" title=" patients’ rights"> patients’ rights</a>, <a href="https://publications.waset.org/abstracts/search?q=South-West%20Nigeria" title=" South-West Nigeria "> South-West Nigeria </a> </p> <a href="https://publications.waset.org/abstracts/34915/patients-rights-an-enquiry-into-the-activities-of-local-psychiatric-centers-managed-by-muslims-in-south-west-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34915.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">502</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">55</span> Human Security: The Boko Haram Menace in Northern Nigeria in the 21st Century</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jimoh%20Yusuf%20Amuda">Jimoh Yusuf Amuda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Human security is a great panacea for sustainable development of world societies.

In this work, tomatoes seeds were exposed to long hours of simulated microgravity condition using a one-axis clinostat. The seeds were sown on a 1.5% combination of plant nutrient and agar-agar solidified medium in three Petri dishes. One of the Petri dishes was mounted on the clinostat and allowed to rotate at the speed of 20 rpm for 72 hours, while the others were subjected to the normal gravity vector. The anatomical sections of both clinorotated and normal gravity plants were made after 72 hours and observed using a Phase-contrast digital microscope. The percentage germination, as well as the growth rate of the normal gravity seeds, was higher than the clinorotated ones. The germinated clinorotated roots followed different directions unlike the normal gravity ones which grew towards the direction of gravity vector. The clinostat was able to switch off gravistimulation. Distinct cellular arrangement was observed for tomatoes under normal gravity condition, unlike those of clinorotated ones. The root epidermis and cortex of normal gravity are thicker than the clinorotated ones. This implied that under long-term microgravity influence, plants do alter their anatomical features as a way of adapting to the stress condition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anatomy" title="anatomy">anatomy</a>, <a href="https://publications.waset.org/abstracts/search?q=clinostat" title=" clinostat"> clinostat</a>, <a href="https://publications.waset.org/abstracts/search?q=germination" title=" germination"> germination</a>, <a href="https://publications.waset.org/abstracts/search?q=lycopersicon%20esculentum" title=" lycopersicon esculentum"> lycopersicon esculentum</a>, <a href="https://publications.waset.org/abstracts/search?q=microgravity" title=" microgravity"> microgravity</a> </p> <a href="https://publications.waset.org/abstracts/58028/growth-and-anatomical-responses-of-lycopersicon-esculentum-tomatoes-under-microgravity-and-normal-gravity-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58028.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">322</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">53</span> Education and Development: An Overview of Islam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rasheed%20Sanusi%20Adeleke">Rasheed Sanusi Adeleke</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Several attempts have been made by scholars, both medieval and contemporary on the impact of Islam on scientific discovery. Lesser attention, however, is always accorded to the historical antecedents of the earlier Muslim scholars, who made frantic efforts towards the discoveries. Islam as a divine religion places high premium on the acquisition of knowledge especially that of sciences. It considers knowledge as a comprehensive whole, which covers both spiritual and material aspects of human life. Islam torches every aspect of human life for the growth, development and advancement of society. Acquisition of knowledge of humanity, social sciences as well as the pure and applied sciences is comprehensively expressed in Islamic education. Not only this, the history portrays the leading indelible roles played by the early Muslims on these various fields of knowledge. That is why Islam has declared acquisition of knowledge compulsory for all Muslims. This paper therefore analyses the contributions of Islam to civilization with particular reference to sciences. It also affirms that Islam is beyond the religion of prayers and rituals. The work is historic, analytic and explorative in nature. Recommendations are also also put forward as suggestions for the present generation cum posterity in general and Muslims in particular. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=education" title="education">education</a>, <a href="https://publications.waset.org/abstracts/search?q=development" title=" development"> development</a>, <a href="https://publications.waset.org/abstracts/search?q=Islam" title=" Islam"> Islam</a>, <a href="https://publications.waset.org/abstracts/search?q=development%20and%20Islam" title=" development and Islam"> development and Islam</a> </p> <a href="https://publications.waset.org/abstracts/8011/education-and-development-an-overview-of-islam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8011.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">434</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">52</span> Creating Shared Value: A Paradigm Shift from Corporate Social Responsibility to Creating Shared Value</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bolanle%20Deborah%20Motilewa">Bolanle Deborah Motilewa</a>, <a href="https://publications.waset.org/abstracts/search?q=E.K.%20Rowland%20Worlu"> E.K.

This responsibility to society is generally termed as corporate social responsibility. For many years, the practice of corporate social responsibility (CSR) was solely philanthropic, where organizations gave ‘charity’ or ‘alms’ to society, without any link to the organization’s mission and objectives. However, there has arisen a shift in the application of CSR from an act of philanthropy to a strategy with a business model engaged in by organizations to create a win-win situation of performing their societal obligation, whilst simultaneously performing their economic obligation. In more recent times, the term has moved from CSR to creating shared value, which is simply corporate policies and practices that enhance the competitiveness of a business organization while simultaneously advancing social and economic conditions in the communities in which the company operates. Creating shared value has in more recent light found more meaning in underdeveloped countries, faced with deep societal challenges that businesses can solve whilst creating economic value. This study thus reviews literature on CSR, conceptualizing the shift to creating shared value and finally viewing its potential significance in Africa’s development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=africapitalism" title="africapitalism">africapitalism</a>, <a href="https://publications.waset.org/abstracts/search?q=corporate%20social%20responsibility" title=" corporate social responsibility"> corporate social responsibility</a>, <a href="https://publications.waset.org/abstracts/search?q=development" title=" development"> development</a>, <a href="https://publications.waset.org/abstracts/search?q=shared%20value" title=" shared value"> shared value</a> </p> <a href="https://publications.waset.org/abstracts/50444/creating-shared-value-a-paradigm-shift-from-corporate-social-responsibility-to-creating-shared-value" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50444.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">278</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">51</span> Quick Sequential Search Algorithm Used to Decode High-Frequency Matrices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20M.%20Siddeq">Mohammed M.

The decoding/decompression uses a search method called QSS (Quick Sequential Search) Decoding Algorithm presented in this research based on the sequential search to recover the exact coefficients. In the next step, the decoded data are saved in an auxiliary array. The basic idea behind the auxiliary array is to save all possible decoded coefficients; this is because another algorithm, such as conventional sequential search, could retrieve encoded/compressed data independently from the proposed algorithm. The experimental results showed that our proposed decoding algorithm retrieves original data faster than conventional sequential search algorithms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=matrix%20minimization%20algorithm" title="matrix minimization algorithm">matrix minimization algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=decoding%20sequential%20search%20algorithm" title=" decoding sequential search algorithm"> decoding sequential search algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20compression" title=" image compression"> image compression</a>, <a href="https://publications.waset.org/abstracts/search?q=DCT" title=" DCT"> DCT</a>, <a href="https://publications.waset.org/abstracts/search?q=DWT" title=" DWT"> DWT</a> </p> <a href="https://publications.waset.org/abstracts/151394/quick-sequential-search-algorithm-used-to-decode-high-frequency-matrices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151394.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">150</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">50</span> Physicochemistry of Pozzolanic Stabilization of a Class A-2-7 Lateritic Soil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20O.%20Apampa">Ahmed O.

The objectives are to establish a nexus between cation exchange capacity of the soil, the alkaline forming compounds in CCA and percentage CCA addition to soil beyond which no more improvement in strength properties can be achieved; and to propose feasible chemical reactions to explain the chemical stabilization of the lateritic soil with CCA alone. The lateritic soil, as well as CCA of pozzolanic quality Class C were separately analysed for their metallic oxide composition using the X-Ray Fluorescence technique. The cation exchange capacity (CEC) of the soil and the CCA were computed theoretically using the percentage composition of the base cations Ca<sup>2+</sup>, Mg<sup>2+</sup> K<sup>+</sup> and Na<sup>2+</sup> as 1.48 meq/100 g and 61.67 meq/100 g respectively, thus indicating a ratio of 0.024 or 2.4%. This figure, taken as the theoretical amount required to just fill up the exchangeable sites of the clay molecules, compares well with the laboratory observation of 1.5% for the optimum level of CCA addition to lateritic soil. The paper went on to present chemical reaction equations between the alkaline earth metals in the CCA and the silica in the lateritic soil to form silicates, thereby proposing an extension of the theory of mechanism of soil stabilization to cover chemical stabilization with pozzolanic ash only. The paper concluded by recommending further research on the molecular structure of soils stabilized with pozzolanic waste ash alone, with a view to confirming the chemical equations advanced in the study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cation%20exchange%20capacity" title="cation exchange capacity">cation exchange capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=corn%20cob%20ash" title=" corn cob ash"> corn cob ash</a>, <a href="https://publications.waset.org/abstracts/search?q=lateritic%20soil" title=" lateritic soil"> lateritic soil</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20stabilization" title=" soil stabilization"> soil stabilization</a> </p> <a href="https://publications.waset.org/abstracts/43830/physicochemistry-of-pozzolanic-stabilization-of-a-class-a-2-7-lateritic-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43830.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">248</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">49</span> Using CFRP Sheets and Anchors on Sand-Lightweight Perlite Concrete to Evaluate the Flexural Behaviour of T-Beams</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Zaki">Mohammed Zaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Hayder%20Rasheed"> Hayder Rasheed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper evaluates the flexural response of sand-lightweight Perlite concrete using full-scale reinforced concrete T beams strengthened and anchored with carbon fiber reinforced polymer (CFRP) materials. Four specimens were prepared with the same geometry, steel reinforcements, concrete properties, and span lengths. The anchored beams had a similar number of CFRP sheets but were secured utilizing different arrangements of CFRP fiber anchors. That will allow for effective and easily making comparisons to examine the flexural strengthening behavior of sand-lightweight Perlite concrete beams with anchors. The experimental outcomes were also compared with the numerical study and the comparisons were discussed. The test results showed an improvement in flexural behavior due to the use of CFRP sheets and anchors. Interestingly, the anchored beams recorded similar ultimate strength regardless of the number of CFRP fiber anchors used due to the failure by excessive wide cracks in the concrete. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=perlite%20concrete" title="perlite concrete">perlite concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=CFRP%20fiber%20anchors" title=" CFRP fiber anchors"> CFRP fiber anchors</a>, <a href="https://publications.waset.org/abstracts/search?q=lightweight%20concrete" title=" lightweight concrete"> lightweight concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=full-scale%20T-beams" title=" full-scale T-beams"> full-scale T-beams</a> </p> <a href="https://publications.waset.org/abstracts/167039/using-cfrp-sheets-and-anchors-on-sand-lightweight-perlite-concrete-to-evaluate-the-flexural-behaviour-of-t-beams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167039.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">86</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">48</span> Investigation on Scattered Dose Rate and Exposure Parameters during Diagnostic Examination Done with an Overcouch X-Ray Tube in Nigerian Teaching Hospital</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gbenga%20Martins">Gbenga Martins</a>, <a href="https://publications.waset.org/abstracts/search?q=Christopher%20J.%20Olowookere"> Christopher J.

The research was carried out using Gamma Scout software installation on the computer system (Laptop) to record the radiation counts, pulse rate, and dose rate. The measurement was employed by placing the detector at 900 to the incident X-ray. Proforma was used for the collection of patients’ data such as age, sex, examination type, and initial diagnosis. Data such as focus skin distance (FSD), body mass index (BMI), body thickness of the patients, the beam output (kVp) were collected at Obafemi Awolowo University, Ile-Ife, Western Nigeria. Total number of 136 patients was considered during this research. Dose rate range between 14.21 and 86.78 µSv/h for the plain abdominal region, 85.70 and 2.86 µSv/h for the lumbosacral region,1.3 µSv/yr and 3.6 µSv/yr in the pelvis region, 2.71 µSv/yr and 28.88 µSv/yr for leg region, 3.06 µSv/yr and 29.98 µSv/yr in hand region. The results of this study were compared with those of other studies carried out in other countries. The findings of this study indicated that the number of exposure parameters selected for each diagnostic examination contributed to the dose rate recorded. Therefore, these results call for a quality assurance program (QAP) in diagnostic X-ray units in Nigerian hospitals. <p class="card-text"><strong>Keywords:</strong> <a
