In order to transcend the scope of hyperbolic functions, in this work, a kind of generalized q-deformed hyperbolic functions (g q-dhf) is presented. By a suitable transformation, through the q deformation parameter, it is shown that these g q-dhf can be expressed in terms of their corresponding standard ones besides they can be reduced to the sc q-dhf. As a useful application of the proposed approach, and considering a class of exactly solvable multi-parameter exponential-type potentials, some new q-deformed quantum interactions models that can be used as interesting alternative in quantum physics and quantum states are presented. Furthermore, due that quantum potential models are conditioned on the q-dependence of the parameters that characterize to the exponential-type potentials, it is shown that many specific cases of q-deformed potentials are obtained as particular cases from the proposal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diatomic%20molecules" title="diatomic molecules">diatomic molecules</a>, <a href="https://publications.waset.org/abstracts/search?q=exponential-type%20potentials" title=" exponential-type potentials"> exponential-type potentials</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperbolic%20functions" title=" hyperbolic functions"> hyperbolic functions</a>, <a href="https://publications.waset.org/abstracts/search?q=q-deformed%20potentials" title=" q-deformed potentials"> q-deformed potentials</a> </p> <a href="https://publications.waset.org/abstracts/82814/generalized-hyperbolic-functions-exponential-type-quantum-interactions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82814.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">184</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">597</span> Focusing on the Utilization of Information and Communication Technology for Improving Childrens’ Potentials in Science: Challenges for Sustainable Development in Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Osagiede%20Mercy%20Afe">Osagiede Mercy Afe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> After the internet explosion in the 90’s, Technology was immediately integrated into the school system. Technology which symbolizes advancement in human knowledge was seen as a setback by many educators many efforts have been made to help stem this erroneous believes and help educators realize the benefits of technology and ways of implementing it in the classrooms especially in the sciences. This advancement created a constantly expanding gap between the pupil’s perception on the use of technology within the learning atmosphere and the teacher’s perception and limitations hence the focus of this paper is on the need to refocus on the potentials of Science and Technology in enhancing children learning at school especially in science for sustainable development in Nigeria. The paper recommended measures for facilitating the sustenance of science and technology in Nigerian schools so as to enhance the potentials of our children in Science and Technology for a better tomorrow. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=children" title="children">children</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20communication%20technology%20%28ICT%29" title=" information communication technology (ICT)"> information communication technology (ICT)</a>, <a href="https://publications.waset.org/abstracts/search?q=potentials" title=" potentials"> potentials</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20development" title="sustainable development">sustainable development</a>, <a href="https://publications.waset.org/abstracts/search?q=science%20education" title=" science education"> science education</a> </p> <a href="https://publications.waset.org/abstracts/22363/focusing-on-the-utilization-of-information-and-communication-technology-for-improving-childrens-potentials-in-science-challenges-for-sustainable-development-in-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22363.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">488</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">596</span> Evaluation and Possibilities of Valorization of Ecotourism Potentials in the Mbam and Djerem National Park</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rinyu%20Shei%20Mercy">Rinyu Shei Mercy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Protected areas are the potential areas for the development of ecotourism because of their biodiversity, landscapes, waterfalls, lakes, caves, salt lick and cultural heritage of local or indigenous people. These potentials have not yet been valorized, so this study will enable to investigate the evaluation and possibilities of valorization of ecotourism potentials in the Mbam and Djerem National Park. Hence, this was done by employing a combination of field observations, examination, data collection and evaluation, using a SWOT analysis. The SWOT provides an analysis to determine the strengths, weaknesses, opportunities and threats, and strategic suggestions for ecological planning. The study helps to determine an ecotouristic inventory and mapping of ecotourism potentials of the park, evaluate the degree of valorization of these potentials and the possibilities of valorization. Finally, the study has proven that the park has much natural potentials such as rivers, salt licks, waterfall and rapids, lakes, caves and rocks, etc. Also, from the study, it was realized that as concerns the degree of valorization of these ecotourism potentials, 50% of the population visit the salt lick of Pkayere because it’s a biodiversity hotspot and rich in mineral salt attracting a lot of animals and the least is the lake Miyere with 1% due to the fact that it is sacred. Moreover, from the results, there are possibilities that these potentials can be valorized and put into use because of their attractive nature such as creating good roads and bridges, good infrastructural facilities, good communication network etc. So, the study recommends that, in this process, MINTOUR, WCS, tour operators must interact sufficiently in order to develop the potential interest to ecotourism, ecocultural tourism and scientific tourism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ecotourism" title="ecotourism">ecotourism</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20park%20Mbam%20and%20Djerem" title=" national park Mbam and Djerem"> national park Mbam and Djerem</a>, <a href="https://publications.waset.org/abstracts/search?q=valorization%20of%20biodiversity" title=" valorization of biodiversity"> valorization of biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=protected%20areas%20of%20Cameroon" title=" protected areas of Cameroon"> protected areas of Cameroon</a> </p> <a href="https://publications.waset.org/abstracts/117741/evaluation-and-possibilities-of-valorization-of-ecotourism-potentials-in-the-mbam-and-djerem-national-park" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117741.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">137</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">595</span> Environmental Potentials within the Production of Asphalt Mixtures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Florian%20Gsch%C3%B6sser">Florian Gschösser</a>, <a href="https://publications.waset.org/abstracts/search?q=Walter%20Purrer"> Walter Purrer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper shows examples for the (environmental) optimization of production processes for asphalt mixtures applied for typical road pavements in Austria and Switzerland.

It is shown that environmental impacts can be reduced by the application of reclaimed asphalt pavement (RAP) and by the optimization of specific production characteristics, e.g. the reduction of the initial moisture of the mineral aggregate and the reduction of the mixing temperature by the application of low-viscosity and foam bitumen. The results of the LCA study demonstrate reduction potentials per cubic meter asphalt of up to 57 % (Global Warming Potential–GWP) and 77 % (Ozone depletion–ODP).

The evoked potentials technique reveals how basic brain processes interact to achieve adequate and flexible behaviours. The objective of this work, using evoked potentials, is to study if it is possible to distinguish if a patient suffers a specific type of learning disorder to decide the possible therapies to follow. The methodology used, is the analysis of the dynamics of different areas of the brain during a cognitive activity to find the relationships between the different areas analyzed in order to better understand the functioning of neural networks. Also, the latest advances in neuroscience have revealed the existence of different brain activity in the learning process that can be highlighted through the use of non-invasive, innocuous, low-cost and easy-access techniques such as, among others, the evoked potentials that can help to detect early possible neuro-developmental difficulties for their subsequent assessment and cure. From the study of the amplitudes and latencies of the evoked potentials, it is possible to detect brain alterations in the learning process specifically in dyscalculia, to achieve specific corrective measures for the application of personalized psycho pedagogical plans that allow obtaining an optimal integral development of the affected people. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dyscalculia" title="dyscalculia">dyscalculia</a>, <a href="https://publications.waset.org/abstracts/search?q=neurodevelopment" title=" neurodevelopment"> neurodevelopment</a>, <a href="https://publications.waset.org/abstracts/search?q=evoked%20potentials" title=" evoked potentials"> evoked potentials</a>, <a href="https://publications.waset.org/abstracts/search?q=Learning%20disabilities" title=" Learning disabilities"> Learning disabilities</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20networks" title=" neural networks"> neural networks</a> </p> <a href="https://publications.waset.org/abstracts/133533/the-latency-amplitude-binomial-of-waves-resulting-from-the-application-of-evoked-potentials-for-the-diagnosis-of-dyscalculia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133533.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">140</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">593</span> Potentials of Underutilised Crops in the Nigerian Farming Systems for Sustainable Food Production and Economic Empowerment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jesse%20Silas%20Mshelia">Jesse Silas Mshelia</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Mamman%20Degri"> Michael Mamman Degri</a>, <a href="https://publications.waset.org/abstracts/search?q=Akeweta%20Emmanuel%20Samaila"> Akeweta Emmanuel Samaila</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This review was conducted in the North-Eastern part of Nigeria where there are a lot of challenges of poverty and low level of productivity of farmlands as a result of dwindling soil fertility and dependence on crops that are not so much adopted to the soil and climatic condition and the prevailing farming systems of the area which is predominantly mixed cropping. The crops that are neglected are well fitted into this system of production and yield better with the low level of input and management and give a higher profit margin.

For this reason, the enzyme inhibitory potentials of different solvent extracts from Linaria genistifolia subsp. genistifolia were investigated against cholinesterase, and tyrosinase. The in vitro enzyme inhibitory potentials were measured with a microplate reader. The acetone and methanol extracts exhibited the strongest enzyme inhibitory effects on cholinesterase.

Farmers in Nigeria still have huge potentials to enhance their productivity. The study argues that the increase in agricultural output due to increased productivity, orchestrated by modern agriculture will promote forward linkages and opportunities in the processing sub-sector; both the manufacturing of machines and the processing of raw materials. Depending on existing incentives, foreign investment could be attracted to augment local investment in the sector. The availability of raw materials in large quantity – which prices are competitive – will attract investment in other industries. In addition, potentials for backward linkages will also be created. In a nutshell, adopting the unbalanced growth theory in favour of the agricultural sector could engender industrialization in a country with untapped potentials. The paper highlights the numerous potentials of modern agriculture that are yet to be tapped in Nigeria and also provides a theoretical analysis of how the realization of such potentials could promote industrialization in the country. The study adopts the Lewis’ theory of structural–change model and Hirschman’s theory of unbalanced growth in the design of the analytical framework. The framework will be useful in empirical studies that will guide policy formulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=modern%20agriculture" title="modern agriculture">modern agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=industrialization" title=" industrialization"> industrialization</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20change%20model" title=" structural change model"> structural change model</a>, <a href="https://publications.waset.org/abstracts/search?q=unbalanced%20growth" title=" unbalanced growth"> unbalanced growth</a> </p> <a href="https://publications.waset.org/abstracts/74840/modern-agriculture-and-industrialization-nexus-in-the-nigerian-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74840.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">303</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">590</span> Method for Assessing Potential in Distribution Logistics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20Gro%C3%9F">B.

CP which is widely used, especially in buried and sub-merged environments, which both environments are susceptible to microbiologically influenced corrosion (MIC). Most of the standards recommend performing CP using -800 mV, however, if MIC threats are high or sulfate reducing bacteria (SRB) is present, the recommendation is to use more negative potentials for adequate protection of the metal. Due to the lack of knowledge and research on the effectiveness of CP on MIC, to the author’s best knowledge, there is no information about what MIC threat is and how much more negative potentials should be used enabling adequate protection and not overprotection (due to hydrogen embrittlement risk). Recently, the development and cheaper price of molecular microbial methods (MMMs) open the door for more effective investigations on the corrosion in the presence of microorganisms, along with other electrochemical methods and surface analysis. In this work, using MMMs, the gene expression of SRB biofilm under different potentials of CP will be investigated. The specific genes, such as pH buffering, metal oxidizing, etc., will be compared at different potentials, enabling to determine the precise potential that protect the metal effectively from SRB. This work is the initial step to be able to standardize the recommended potential under MIC condition, resulting better protection for the infrastructures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cathodic%20protection" title="cathodic protection">cathodic protection</a>, <a href="https://publications.waset.org/abstracts/search?q=microbiologically%20influenced%20corrosion" title=" microbiologically influenced corrosion"> microbiologically influenced corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20microbial%20methods" title=" molecular microbial methods"> molecular microbial methods</a>, <a href="https://publications.waset.org/abstracts/search?q=sulfate%20reducing%20bacteria" title=" sulfate reducing bacteria"> sulfate reducing bacteria</a> </p> <a href="https://publications.waset.org/abstracts/158046/the-effectiveness-of-cathodic-protection-on-microbiologically-influenced-corrosion-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158046.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">92</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">588</span> The Potential of 48V HEV in Real Driving Operation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mark%20Schudeleit">Mark Schudeleit</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Sieg"> Christian Sieg</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferit%20K%C3%BC%C3%A7%C3%BCkay"> Ferit Küçükay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This publication focuses on the limits and potentials of 48V hybrid systems, which are especially due to the cost advantages an attractive alternative, compared to established high volt-age HEVs and thus will gain relevant market shares in the future. Firstly, at market overview is given which shows the current known 48V hybrid concepts and demonstrators. These topologies will be analyzed and evaluated regarding the system power and the battery capacity as well as their implemented hybrid functions. The potential in fuel savings and CO2 reduction is calculated followed by the customer-relevant dimensioning of the electric motor and the battery. For both measured data of the real customer operation is used. Subsequently, the CO2 saving potentials of the customer-oriented dimensioned powertrain will be presented for the NEDC and the customer operation. With a comparison of the newly defined drivetrain with existing 48V systems the question can be answered whether current systems are dimensioned optimally for the customer operation or just for legislated driving cycles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=48V%20hybrid%20systems" title="48V hybrid systems">48V hybrid systems</a>, <a href="https://publications.waset.org/abstracts/search?q=market%20comparison" title=" market comparison"> market comparison</a>, <a href="https://publications.waset.org/abstracts/search?q=requirements%20and%20potentials%20in%20customer%20operation" title=" requirements and potentials in customer operation"> requirements and potentials in customer operation</a>, <a href="https://publications.waset.org/abstracts/search?q=customer-oriented%20dimensioning" title=" customer-oriented dimensioning"> customer-oriented dimensioning</a>, <a href="https://publications.waset.org/abstracts/search?q=CO2%20savings" title=" CO2 savings"> CO2 savings</a> </p> <a href="https://publications.waset.org/abstracts/30122/the-potential-of-48v-hev-in-real-driving-operation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30122.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">550</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">587</span> Agricultural Solid Wastes Generation in Nigeria and Their Recycling Potentials into Building Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Usman%20Aliyu%20Jalam">Usman Aliyu Jalam</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuaibu%20Alolo%20Sumaila"> Shuaibu Alolo Sumaila</a>, <a href="https://publications.waset.org/abstracts/search?q=Sa%E2%80%99adiya%20Iliyasu%20Muhammed"> Sa’adiya Iliyasu Muhammed </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Modern building industry lays much emphasis on sophisticated materials that have high embodied energy with intrinsic distinctiveness for damaging the environment. But today, advances in solid waste management have resulted in alternative building materials as partial or complete replacement of the conventional materials like cement, aggregate etc particularly for low cost housing. Investigations carried out revealed that an estimated 18.0 million tonnes of agricultural solid wastes are being generated in Nigeria annually. This constitutes a problem not only to the natural environment but also to the built environment more particularly with the way the wastes are being dispose of. The paper has discussed the present status on the generation and utilisation of agricultural solid wastes, their recycling potentials and environmental implications. It further discovered that although considerable quantity of these wastes were found to have the potentials of being recycled as building materials, the availability of the appropriate technology remains a big challenge in the country. Moreover, majority of the wastes type have gained popularity as fuel. As such, the economic and environmental benefits of recycling the wastes and the use of the wastes as fuel need further investigation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agricultural%20waste" title="agricultural waste">agricultural waste</a>, <a href="https://publications.waset.org/abstracts/search?q=building" title=" building"> building</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=materials" title=" materials"> materials</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria" title=" Nigeria"> Nigeria</a> </p> <a href="https://publications.waset.org/abstracts/6662/agricultural-solid-wastes-generation-in-nigeria-and-their-recycling-potentials-into-building-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6662.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">400</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">586</span> Molecular Characterization and Determination of Bioremediation Potentials of Some Bacteria Isolated from Spent Oil Contaminated Soil Mechanic Workshops in Kaduna Metropolis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20D.%20Adams">David D.

The bacterial isolates were morphologically and molecularly identified as Enterobacter hormaechei, Escherichia coli, Klebsiella pneumoniae, Shigella flexneri , Wesiella cibaria, Lactobacillus planetarium. The singles and a consortium of these bacteria incubated in the minimal salt medium incorporated with 1% engine oil exhibited various biodegradation rates, with the mixed consortium exhibiting the highest for this oil. The gene for the hydrocarbon enzyme Catechol 2, 3 dioxygenase (C2,30) was detected and amplified in Enterobacter hormaechei, Escherichia coli and Shigella flexneri using PCR and Agarose gel electrophoresis. The detection of the (C2,30) enzyme gene in, and the spent oil biodegradation activity exhibited by these bacteria suggest their possible possession of bioremediating potentials for the spent engine oil. It is therefore suggested that a pilot study on the field application of these bacteria for bioremediation and restoration of spent oil polluted environment should be done in mechanic workshops. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spent%20engine%20oil" title="spent engine oil">spent engine oil</a>, <a href="https://publications.waset.org/abstracts/search?q=pollution" title=" pollution"> pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=bacteria" title=" bacteria"> bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=enzyme" title=" enzyme"> enzyme</a>, <a href="https://publications.waset.org/abstracts/search?q=bioremediation" title=" bioremediation"> bioremediation</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanic%20workshop" title=" mechanic workshop"> mechanic workshop</a> </p> <a href="https://publications.waset.org/abstracts/78069/molecular-characterization-and-determination-of-bioremediation-potentials-of-some-bacteria-isolated-from-spent-oil-contaminated-soil-mechanic-workshops-in-kaduna-metropolis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78069.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">222</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">585</span> Processing Mild versus Strong Violations in Music: A Pilot Study Using Event-Related Potentials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marie-Eve%20Joret">Marie-Eve Joret</a>, <a href="https://publications.waset.org/abstracts/search?q=Marijn%20Van%20Vliet"> Marijn Van Vliet</a>, <a href="https://publications.waset.org/abstracts/search?q=Flavio%20Camarrone"> Flavio Camarrone</a>, <a href="https://publications.waset.org/abstracts/search?q=Marc%20M.%20Van%20Hulle"> Marc M.

The negative impacts of the encampment policy include the lack of participation or access to opportunities outside the refugee camps such as employment, education, and local integration, unfair imprisonments and constant alienation of refugees, mental and physical health issues, just to name a few. Evidence suggests that refugee camps in East Africa have progressively become open detention centres due to their designs, their locations, and movement restrictions imposed on refugees. Such restrictions in a region that hosts millions of refugees do not only undermine refugees’ potentials, but it also hurts the local economy- host countries miss out in many ways. Outlining the negative impacts of the encampment policy will enable governments and relevant non-governmental actors, including policymakers, to re-consider this policy with the aim to improve refugees’ participation and contributions in the broader society, promote socially cohesive practices, and help millions of refugees gain independence and reach their potentials financially, socially and politically, finally and truly giving the voice to the voiceless. The encampment policy undermines the general human security in East Africa, and it is one of the migration practices showcasing East African governments’ lack of will to protect human rights, especially within the most vulnerable population groups such as refugees. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=migration%20policy" title="migration policy">migration policy</a>, <a href="https://publications.waset.org/abstracts/search?q=immigration" title=" immigration"> immigration</a>, <a href="https://publications.waset.org/abstracts/search?q=refugees" title=" refugees"> refugees</a>, <a href="https://publications.waset.org/abstracts/search?q=encampment" title=" encampment"> encampment</a>, <a href="https://publications.waset.org/abstracts/search?q=migration" title=" migration"> migration</a>, <a href="https://publications.waset.org/abstracts/search?q=integration" title=" integration"> integration</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20cohesion" title=" social cohesion"> social cohesion</a> </p> <a href="https://publications.waset.org/abstracts/129231/a-migration-policy-gone-wrong-a-study-on-how-the-encampment-policy-undermines-refugees-potentials-and-fails-local-economy-a-case-of-east-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129231.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">133</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">583</span> South Asia as an Emerging Region of the World 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=Shazia%20Shinwari">Shazia Shinwari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the 21st century, South Asia is becoming one of the rising sub-regions of the world. In the whole of Asia, South Asia is going to be the center part of opportunities, development, and challenges. The increasing economy and its geopolitical importance are changing the landscape of South Asia. Despite intensifying the opportunities and development, the region is also facing the challenges of security, poverty, and conflicts. It is one of the most populated sub-regions and has many internal conflicts because of which the region remains for a long time a least developed region in the world. But now South Asia is transforming into the developing process and trying to utilize its potentials and to remove the hurdles in the way of development. South Asia is one of the distinctive regions of the world and could play an important role at the global level if the potentials of the region are properly utilized. South Asia is one of the most important regions of the world and assumed more importance after the British withdrawal from the region. Now South Asia is playing an important role in world politics due to its strategic and geographical location. That is why the importance of this region in the international political systems cannot be ignored. Day by day, changes have been taking place in the structure of the global economy, and South Asia could take advantage of these changes to advance as an economic region. For this, South Asia will need to look at its history, and that changes, particularly in the India and Pakistan relations, are necessary for the development of the South Asian region. Despite having challenges in the region, South Asia is also rising as the land of opportunities and development if the potentials of the region are properly utilized and smoothen the way for regional integration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=challenges" title="challenges">challenges</a>, <a href="https://publications.waset.org/abstracts/search?q=development" title=" development"> development</a>, <a href="https://publications.waset.org/abstracts/search?q=opportunities" title=" opportunities"> opportunities</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Asia" title=" South Asia"> South Asia</a> </p> <a href="https://publications.waset.org/abstracts/130350/south-asia-as-an-emerging-region-of-the-world-in-the-21st-century" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130350.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">582</span> Robot Control by ERPs of Brain Waves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20T.%20Sun">K.

A specific component of ERPs, N2P3, was found and used to control the movement of robot and the view of camera on the designed brain-computer interface (BCI). Users only required watching the stimuli of attended button on the BCI, the evoked potentials of brain waves of the target button, N2P3, had the greatest amplitude among all control buttons. An experimental scene had been constructed that the robot required walking to a specific position and move the view of camera to see the instruction of the mission, and then completed the task. Twelve volunteers participated in this experiment, and experimental results showed that the correct rate of BCI control achieved 80% and the average of execution time was 353 seconds for completing the mission. Four main contributions included in this research: (1) find an efficient component of ERPs, N2P3, for BCI control, (2) embed robot's viewpoint image into user interface for robot control, (3) design an experimental scene and conduct the experiment, and (4) evaluate the performance of the proposed system for assessing the practicability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=severe%20physical%20disabilities" title="severe physical disabilities">severe physical disabilities</a>, <a href="https://publications.waset.org/abstracts/search?q=robot%20control" title=" robot control"> robot control</a>, <a href="https://publications.waset.org/abstracts/search?q=event-related%20potentials%20%28ERPs%29" title=" event-related potentials (ERPs)"> event-related potentials (ERPs)</a>, <a href="https://publications.waset.org/abstracts/search?q=brain-computer%20interface%20%28BCI%29" title=" brain-computer interface (BCI)"> brain-computer interface (BCI)</a>, <a href="https://publications.waset.org/abstracts/search?q=brain%20waves" title=" brain waves"> brain waves</a> </p> <a href="https://publications.waset.org/abstracts/11425/robot-control-by-erps-of-brain-waves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11425.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">369</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">581</span> Community Development and Preservation of Heritage in Igbo Area of Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elochukwu%20A.%20Nwankwo">Elochukwu A.

Aim: The correlations of the polyphenolic compounds in the hypoglycemic potential of different extracts of leaves of A. godseffiana and their safety profile on cell lines were investigated. Materials and Methods: The phytochemical compositions and antioxidants potentials were determined using adopted methods. An in vitro approach was employed in determining the hypoglycemic potentials of the extracts on α-amylase and α-glucosidase. The Line weaver-Burke plot was used to evaluate the mechanisms of Inhibition mechanisms of the enzymes. Results and Conclusions: Antioxidants results revealed that total antioxidant capacity (TAC) of the acetone extract (IC50: 0.34 mg/mL) showed better activity compared to the standards (silymarine 0.52 mg/mL; gallic acid 0.51 mg/mL). In-vitro hypoglycemic activity of the extracts confirmed that acetone extract demonstrated strong and mild inhibitory potential against α-amylase and α-glucosidase respectively. The observed activity was concentration-dependent with IC50 values of 2.33 and 0.13 mg/mL. The observed hypoglycemic and anti-oxidant potentials of acetone extract A. godseffiana correlate to its high polyphenolic contents which include phenols (133.20 mg gallic acid g-1), flavonoid (350.60 mg quercetin g-1) and tannins (264.67 mg catechin g-1). The mechanisms of action exhibited by acetone extract of A. godseffiana were mixed non-competitive and uncompetitive; which can be attributed to its inhibitory properties on α-amylase and α-glucosidase respectively. This effect would cause reduction in the rate at which starch hydrolyse, boost palliated glucose levels; hence, making acetone extract of A. godseffiana a potential anti-hypoglycemic alternative. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Acalypha%20godeseffiana" title="Acalypha godeseffiana">Acalypha godeseffiana</a>, <a href="https://publications.waset.org/abstracts/search?q=acetone%20extract" title=" acetone extract"> acetone extract</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-hypoglycemia" title=" anti-hypoglycemia"> anti-hypoglycemia</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title=" antioxidant"> antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=phytochemicals" title=" phytochemicals"> phytochemicals</a> </p> <a href="https://publications.waset.org/abstracts/61511/the-role-of-polyphenolic-compounds-in-the-alpha-amylase-and-alpha-glucosidase-inhibitory-potentials-of-extracts-from-the-leaves-of-acalypha-godseffiana-from-eastern-nigeria-an-in-vitro-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61511.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">262</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">578</span> The Hypolipidemic and Anti-Nephrotoxic Potentials of Vernonia calvoana Extract in Acetaminophen-Treated Male Wistar Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Godwin%20E.%20Egbung">Godwin E.

Thirty-five (35) male albino Wistar rats weighing 100-150 g were divided into five (5) groups of seven rats each. Group 1 served as normal control, group 2 received normal saline after treatment with Acetaminophen (PCM), group 3 was treated with VC extracts (200 mg/kg body weight), group 4 received VC extracts ( 400 mg/kg body weight) and group 5 was administered 100 mg/kg body weight of Vitamin E. At the end of the 21 days treatment period, the animals were sacrificed using chloroform vapours, and blood was collected via cardiac puncture and used for analyses of haematological as well as biochemical indices. Results: Results indicated significant decreases (p < 0.001) in LDL-c, TC and TG levels in groups 3,4 and 5 relative to both the control as well as group 2, the atherogenic index showed a significant decrease at p < 0.001) in all treated groups compared with control and PCM- treated group. However, both extracts treated groups and vitamin E treated group showed significant (p < 0.001) increase in HDL-c relative to the control and PCM treated group. Serum potassium concentration was significantly (p < 0.05 and 0.001) reduced across all the treated groups compared with control and PCM- treated groups. Group 4 showed significant (p < 0.001) increase in RBC count, Hb, and PCV compared with PCM- treated group. Conclusions: We therefore conclude that ethanolic leaf extract of VC possesses probable anti-anemic, hypolipidemic potentials, and also ameliorates serum electrolyte imbalance in paracetamol- induced toxicity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acetaminophen" title="acetaminophen">acetaminophen</a>, <a href="https://publications.waset.org/abstracts/search?q=haematological%20indices" title=" haematological indices"> haematological indices</a>, <a href="https://publications.waset.org/abstracts/search?q=hypolipidemic%20potentials" title=" hypolipidemic potentials"> hypolipidemic potentials</a>, <a href="https://publications.waset.org/abstracts/search?q=serum%20lipid%20profile" title=" serum lipid profile"> serum lipid profile</a>, <a href="https://publications.waset.org/abstracts/search?q=vernonia%20calvoana" title=" vernonia calvoana"> vernonia calvoana</a>, <a href="https://publications.waset.org/abstracts/search?q=wistar%20rats" title=" wistar rats"> wistar rats</a> </p> <a href="https://publications.waset.org/abstracts/45628/the-hypolipidemic-and-anti-nephrotoxic-potentials-of-vernonia-calvoana-extract-in-acetaminophen-treated-male-wistar-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45628.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">261</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">577</span> Generation of Electro-Encephalography Readiness Potentials by Intention</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seokbeen%20Lim">Seokbeen Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Gilwon%20Yoon"> Gilwon Yoon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The readiness potential in brain waves is a brain activity related with an intention whose potential arises even before its conscious intention. This study was carried out in order to understand the generation and mechanism of the readiness potential more. The experiment with two subjects was conducted in two ways following the Oddball task protocol. Firstly, auditory stimuli were randomly presented to the subjects. The subject was allowed to press the keyboard with the right index finger only when the subject heard the target stimulus but not the standard stimulus. Secondly, unlike the first one, the auditory stimuli were randomly presented, and the subjects pressed the keyboard in the same manner, but at the same time with grasping action of the left hand. The readiness potential showed up for both of these experiments. In the first Oddball experiment, the readiness potential was detected only when the target stimulus was presented. However, in the second Oddball experiment with the left hand action of grasping something, the readiness potential was detected at the presentation of for both standard and target stimuli. However, detected readiness potentials with the target stimuli were larger than those of the standard stimuli. We found an interesting phenomenon that the readiness potential was able to be detected even the standard stimulus. This indicates that motor-related readiness potentials can be generated only by the intention to move. These results present a new perspective in psychology and brain engineering since subconscious brain action may be prior to conscious recognition of the intention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=readiness%20potential" title="readiness potential">readiness potential</a>, <a href="https://publications.waset.org/abstracts/search?q=auditory%20stimuli" title=" auditory stimuli"> auditory stimuli</a>, <a href="https://publications.waset.org/abstracts/search?q=event-related%20potential" title=" event-related potential"> event-related potential</a>, <a href="https://publications.waset.org/abstracts/search?q=electroencephalography" title=" electroencephalography"> electroencephalography</a>, <a href="https://publications.waset.org/abstracts/search?q=oddball%20task" title=" oddball task"> oddball task</a> </p> <a href="https://publications.waset.org/abstracts/88547/generation-of-electro-encephalography-readiness-potentials-by-intention" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88547.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">204</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">576</span> Rural Tourism Entrepreneurship as Strategy for Economic Development in Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salami%20Ayobami%20Taofeek">Salami Ayobami Taofeek</a>, <a href="https://publications.waset.org/abstracts/search?q=Ajayi%20Adeola"> Ajayi Adeola</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rural tourism entrepreurship is a tourist industry which revolutionizes businesses and prompting economic development across the globe. It encompasses huge range activities, natural or man-made attractions, amenities and facilities, transportation, marketing and information systems. It is also an important export for 83% of the developing countries and the main export for one third of them. In 2000, developing countries recorded 142.6 million international arrivals an increase of 95% compared to the figures of 1990. However, only developing countries with effective natural and man-made tourism supporting and enhancing infrastructure have been able to develop their tourism sector and seize the attendance advantages. Rural areas of Nigeria possess some distinctive peculiarities which can be transformed into attractive tourist centers. In spite of all these, rural tourism areas are still faced with myriad problems which include poor finance inadequate awareness and education, lack of progress in developing the rural of progress in developing the rural tourism potentials inadequate legislation, insecurity, entrepreneurial inertness, over-dependent on oil among others. This paper focuses on the impact and challenges of rural tourism entrepreneurship as strategy for economic development in Nigeria. It reviews literature rural tourism, tourism entrepreneurship potentials and classifications of Nigerians tourism potential’s destinations. The paper concludes that Nigeria Government should encourage rural based tourism entrepreneurship development by addressing the challenges facing rural tourism entrepreneurship in the country. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entrepreneurship" title="entrepreneurship">entrepreneurship</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20development" title=" economic development"> economic development</a>, <a href="https://publications.waset.org/abstracts/search?q=rural%20tourism" title=" rural tourism"> rural tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism%20destinations%20tourism%20potentials" title=" tourism destinations tourism potentials"> tourism destinations tourism potentials</a> </p> <a href="https://publications.waset.org/abstracts/37989/rural-tourism-entrepreneurship-as-strategy-for-economic-development-in-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37989.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">431</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">575</span> Participation, Network, Women’s Competency, and Government Policy Affecting on Community Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nopsarun%20Vannasirikul">Nopsarun Vannasirikul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purposes of this research paper were to study the current situations of community development, women’s potentials, women’s participation, network, and government policy as well as to study the factors influencing women’s potentials, women’s participation, network, and government policy that have on the community development.

In the experiment of visual evoked potentials (VEPs), the subjects were asked to gaze at a center point on the monitor screen where the stimuli were provided by the reversal pattern of the checkerboard. In consequence of the VEP experiments, we observed consistent reactions. Each peak voltage could be measured when the ensemble average was applied. Visual stimuli had smaller amplitude and a longer latency compared to that of auditory stimuli. The amplitude was the highest with Target and the smallest with Standard in both stimuli. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=auditory%20stimulus" title="auditory stimulus">auditory stimulus</a>, <a href="https://publications.waset.org/abstracts/search?q=EEG" title=" EEG"> EEG</a>, <a href="https://publications.waset.org/abstracts/search?q=event%20related%20potential" title=" event related potential"> event related potential</a>, <a href="https://publications.waset.org/abstracts/search?q=oddball%20task" title=" oddball task"> oddball task</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20stimulus" title=" visual stimulus"> visual stimulus</a> </p> <a href="https://publications.waset.org/abstracts/62590/event-related-potentials-in-terms-of-visual-and-auditory-stimuli" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62590.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">283</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">572</span> Analysis of the Touch and Step Potential Characteristics of an Earthing System Based on Finite Element Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nkwa%20Agbor%20Etobi%20Arreneke">Nkwa Agbor Etobi Arreneke</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A well-designed earthing/grounding system will not only provide an effective path for direct dissipation of faulty currents into the earth/soil, but also ensure the safety of personnels withing and around its immediate surrounding perimeter is free from the possibility of fatal electric shock. In order to achieve the latter, it is of paramount importance to ensuring that both the step and touch potentials are kept within the allowable tolerance set by standards IEEE Std-80-2000. In this article, the step and touch potentials of an earthing system are simulated and conformity verified using the Finite Element Method (FEM), and has been found to be 242.4V and 194.80V respectively. The effect of injection current position is also analyzed to observe its effect on a person within or in contact with any active part of the earthing system of the substation. The values obtained closely matches those of other published works which made using different numerical methods and/or simulations Genetic Algorithm (GA). This current study is aimed at throwing more light to the dangers of step and touch potential of earthing systems of substation and electrical facilities as a whole, and the need for further in-dept analysis of these parameters. Observations made on this current paper shows that, the position of contact with an energize earthing system is of paramount important in determining its effect on living organisms in contact with any energized part of the earthing systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earthing%2Fgrounding%20systems" title="earthing/grounding systems">earthing/grounding systems</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method%20%28fem%29" title=" finite element method (fem)"> finite element method (fem)</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%2Fearth%20resistance" title=" ground/earth resistance"> ground/earth resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=safety" title=" safety"> safety</a>, <a href="https://publications.waset.org/abstracts/search?q=touch%20and%20step%20potentials" title=" touch and step potentials"> touch and step potentials</a>, <a href="https://publications.waset.org/abstracts/search?q=generic%20algorithm" title=" generic algorithm"> generic algorithm</a> </p> <a href="https://publications.waset.org/abstracts/170779/analysis-of-the-touch-and-step-potential-characteristics-of-an-earthing-system-based-on-finite-element-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170779.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">99</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">571</span> Ab Initio Spectroscopic Study of the Electronic Properties of the (Bana)+ Molecular Ion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tahani%20H.%20Alluhaybi">Tahani H.

The (BaNa)+ molecular ion is considered a two-electron thank to a non-empirical pseudo-potentials approach applied to Ba and Na cores with the Core Polarization Potentials operator (CPP). Then, we performed the Full Configuration Interaction (FCI) method. Accordingly, we calculated the adiabatic Potential Energy Curves (PECs) and their spectroscopic constants (well depth De, transition energies Te, the equilibrium distances Re, vibrational constant ⍵e, and anharmonic constant ⍵exe) for 10 electronic states in Σ+ symmetry. Then we determined the vibrational level energies and their spacing, and the electric Permanent Dipole Moments (PDM). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ab%20initio" title="Ab initio">Ab initio</a>, <a href="https://publications.waset.org/abstracts/search?q=dipole%20moment" title=" dipole moment"> dipole moment</a>, <a href="https://publications.waset.org/abstracts/search?q=non-empirical%20pseudo-potential" title=" non-empirical pseudo-potential"> non-empirical pseudo-potential</a>, <a href="https://publications.waset.org/abstracts/search?q=potential%20energy%20curves" title=" potential energy curves"> potential energy curves</a>, <a href="https://publications.waset.org/abstracts/search?q=spectroscopic%20constants" title=" spectroscopic constants"> spectroscopic constants</a>, <a href="https://publications.waset.org/abstracts/search?q=vibrational%20energy" title=" vibrational energy"> vibrational energy</a> </p> <a href="https://publications.waset.org/abstracts/152989/ab-initio-spectroscopic-study-of-the-electronic-properties-of-the-bana-molecular-ion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152989.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">113</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">570</span> Solubility of Carbon Dioxide in Methoxy and Nitrile-Functionalized Ionic Liquids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20A.%20Bruzon">D.

The capture, sequestration, and conversion of carbon dioxide to other products such as methane or ethanol are ways to control excessive emissions. Ionic liquids have shown great potential among the materials studied as carbon capture solvents and catalysts in the reduction of CO2. In this study, ionic liquids comprising of a methoxy (-OCH3) and cyano (-CN) functionalized imidazolium cation, [MOBMIM] and [CNBMIM] respectively, paired with tris(pentafluoroethyl)trifluorophosphate [FAP] anion were evaluated as effective capture solvents, and organocatalysts in the reduction of CO2. An in-situ electrochemical set-up, which can measure controlled amounts of CO2 both in the gas and in the ionic liquid phase, was used. Initially, reduction potentials of CO2 in the CO2-saturated ionic liquids containing the internal standard cobaltocene were determined using cyclic voltammetry. Chronoamperometric transients were obtained at potentials slightly less negative than the reduction potentials of CO2 in each ionic liquid. The time-dependent current response was measured under a controlled atmosphere. Reduction potentials of CO2 in methoxy and cyano-functionalized [FAP] ionic liquids were observed to occur at ca. -1.0 V (vs. Cc+/Cc), which was significantly lower compared to the non-functionalized analog [PMIM][FAP], with an observed reduction potential of CO2 at -1.6 V (vs. Cc+/Cc). This decrease in the potential required for CO2 reduction in the functionalized ionic liquids shows that the functional groups methoxy and cyano effectively decreased the free energy of formation of the radical anion CO2●⁻, suggesting that these electrolytes may be used as organocatalysts in the reduction of the greenhouse gas. However, upon analyzing the solubility of the gas in each ionic liquid, [PMIM][FAP] showed the highest absorption capacity, at 4.81 mM under saturated conditions, compared to [MOBMIM][FAP] at 1.86 mM, and [CNBMIM][FAP] at 0.76 mM. Also, calculated Henry’s constant determined from the concentration-pressure graph of each functionalized ionic liquid shows that the groups -OCH3 and -CN attached terminal to a C4 alkyl chain do not significantly improve CO2 solubility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20capture" title="carbon capture">carbon
