Jimoh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper examines the mechanism of pozzolan-soil reactions, using a recent study on the chemical stabilization of a Class A-2-7 (3) lateritic soil, with corn cob ash (CCA) as case study. 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">1395</span> Measuring Financial Asset Return and Volatility Spillovers, with Application to Sovereign Bond, Equity, Foreign Exchange and Commodity Markets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Petra%20Palic">Petra Palic</a>, <a href="https://publications.waset.org/abstracts/search?q=Maruska%20Vizek"> Maruska Vizek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We provide an in-depth analysis of interdependence of asset returns and volatilities in developed and developing countries. The analysis is split into three parts. In the first part, we use multivariate GARCH model in order to provide stylized facts on cross-market volatility spillovers. In the second part, we use a generalized vector autoregressive methodology developed by Diebold and Yilmaz (2009) in order to estimate separate measures of return spillovers and volatility spillovers among sovereign bond, equity, foreign exchange and commodity markets. In particular, our analysis is focused on cross-market return, and volatility spillovers in 19 developed and developing countries. In order to estimate named spillovers, we use daily data from 2008 to 2017. In the third part of the analysis, we use a generalized vector autoregressive framework in order to estimate total and directional volatility spillovers. We use the same daily data span for one developed and one developing country in order to characterize daily volatility spillovers across stock, bond, foreign exchange and commodities markets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross-market%20spillovers" title="cross-market spillovers">cross-market spillovers</a>, <a href="https://publications.waset.org/abstracts/search?q=sovereign%20bond%20markets" title=" sovereign bond markets"> sovereign bond markets</a>, <a href="https://publications.waset.org/abstracts/search?q=equity%20markets" title=" equity markets"> equity markets</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20at%20risk%20%28VAR%29" title=" value at risk (VAR)"> value at risk (VAR)</a> </p> <a href="https://publications.waset.org/abstracts/72158/measuring-financial-asset-return-and-volatility-spillovers-with-application-to-sovereign-bond-equity-foreign-exchange-and-commodity-markets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72158.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">1394</span> Functionalized Nano porous Ceramic Membranes for Electrodialysis Treatment of Harsh Wastewater</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emily%20Rabe">Emily Rabe</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephanie%20Candelaria"> Stephanie Candelaria</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachel%20Malone"> Rachel Malone</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivia%20Lenz"> Olivia Lenz</a>, <a href="https://publications.waset.org/abstracts/search?q=Greg%20Newbloom"> Greg Newbloom</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrodialysis (ED) is a well-developed technology for ion removal in a variety of applications. However, many industries generate harsh wastewater streams that are incompatible with traditional ion exchange membranes. Membrion® has developed novel ceramic-based ion exchange membranes (IEMs) offering several advantages over traditional polymer membranes: high performance in low pH, chemical resistance to oxidizers, and a rigid structure that minimizes swelling. These membranes are synthesized with our patented silane-based sol-gel techniques. The pore size, shape, and network structure are engineered through a molecular self-assembly process where thermodynamic driving forces are used to direct where and how pores form. Either cationic or anionic groups can be added within the membrane nanopore structure to create cation- and anion-exchange membranes. The ceramic IEMs are produced on a roll-to-roll manufacturing line with low-temperature processing. Membrane performance testing is conducted using in-house permselectivity, area-specific resistance, and ED stack testing setups. Ceramic-based IEMs show comparable performance to traditional IEMs and offer some unique advantages. Long exposure to highly acidic solutions has a negligible impact on ED performance. Additionally, we have observed stable performance in the presence of strong oxidizing agents such as hydrogen peroxide. This stability is expected, as the ceramic backbone of these materials is already in a fully oxidized state. This data suggests ceramic membranes, made using sol-gel chemistry, could be an ideal solution for acidic and/or oxidizing wastewater streams from processes such as semiconductor manufacturing and mining. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ion%20exchange" title="ion exchange">ion exchange</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane" title=" membrane"> membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=silane%20chemistry" title=" silane chemistry"> silane chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=nanostructure" title=" nanostructure"> nanostructure</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater" title=" wastewater"> wastewater</a> </p> <a href="https://publications.waset.org/abstracts/163226/functionalized-nano-porous-ceramic-membranes-for-electrodialysis-treatment-of-harsh-wastewater" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163226.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">1393</span> Steps towards the Development of National Health Data Standards in Developing Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdullah%20I.%20Alkraiji">Abdullah I.

The government role and support in standardization for health data are thought to be crucial in order to establish credible standards for the next decade, to maximize interoperability across the health sector, and to decrease the risks associated with the implementation of non-standard systems. The normative literature missed out the exploration of the different steps required to be undertaken by the government towards the development of national health data standards. Based on the lessons learned from a qualitative study investigating the different issues to the adoption of health data standards in the major tertiary hospitals in Saudi Arabia and the opinions and feedback from different experts in the areas of data exchange and standards and medical informatics in Saudi Arabia and UK, a list of steps required towards the development of national health data standards was constructed. Main steps are the existence of: a national formal reference for health data standards, an agreed national strategic direction for medical data exchange, a national medical information management plan and a national accreditation body, and more important is the change management at the national and organizational level. The outcome of this study can be used by academics and practitioners to develop the planning of health data standards, and in particular those in developing countries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interoperabilty" title="interoperabilty">interoperabilty</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20data%20exchange" title=" medical data exchange"> medical data exchange</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20data%20standards" title=" health data standards"> health data standards</a>, <a href="https://publications.waset.org/abstracts/search?q=case%20study" title=" case study"> case study</a>, <a href="https://publications.waset.org/abstracts/search?q=Saudi%20Arabia" title=" Saudi Arabia"> Saudi Arabia</a> </p> <a href="https://publications.waset.org/abstracts/3844/steps-towards-the-development-of-national-health-data-standards-in-developing-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3844.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">338</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">1392</span> Empowering Leadership and Constructive Voice: A Sequential Mediation Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Umamaheswara%20Rao%20Jada">Umamaheswara Rao Jada</a>, <a href="https://publications.waset.org/abstracts/search?q=Susmita%20Mukhopadhyay"> Susmita Mukhopadhyay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present highly complex, dynamic and interdependent organizational environment, employees' ideas, opinions and suggestions which is technically referred to as ‘constructive employee voice’ is increasingly being recognized and valued. Literature has consistently demonstrated the relevance of leadership in employee voicing behavior, however the new form of leadership, ‘empowering leadership’ has not been given much attention. The study, therefore, devotes itself to the effort to explore the impact of this new form of leadership on employee voice behavior and the interplay with leader member exchange (LMX) and psychological safety as mediators in the same. The study utilizes structural equation modeling for analyzing the data collected from 310 Indian service industry employees through the questionnaire developed for the study. The findings of the study demonstrate the significant impact of empowering form of leadership on employees’ constructive voice behavior. Additionally, supporting results were observed for the mediating impact of leader member exchange (LMX) and psychological safety between empowering leadership and employees’ constructive voice behavior. The results of this study provide insights into the intervening mechanisms by linking leaders’ empowering behavior with employees’ constructive voice, while also highlighting the potential importance of LMX relationship in organizations and psychological safety in the context of constructive voice behavior. The study brings forth the relevance of the new form of leadership, ‘empowering leadership’ for fostering the better exchange of ideas, opinions, and suggestions between leaders and followers which tend to benefit the organization, providing empirical evidence of the sequential mediation of LMX and psychological safety. The piece of work is assumed to benefit the leaders in organizations by providing them the basis for adopting empowering form of leadership in light of results displayed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constructive%20voice" title="constructive voice">constructive voice</a>, <a href="https://publications.waset.org/abstracts/search?q=empowering%20leadership" title=" empowering leadership"> empowering leadership</a>, <a href="https://publications.waset.org/abstracts/search?q=leader%20member%20exchange%20%28LMX%29" title=" leader member exchange (LMX)"> leader member exchange (LMX)</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20safety" title=" psychological safety"> psychological safety</a>, <a href="https://publications.waset.org/abstracts/search?q=sequential%20mediation" title=" sequential mediation"> sequential mediation</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20equation%20modeling" title=" structural equation modeling"> structural equation modeling</a> </p> <a href="https://publications.waset.org/abstracts/71223/empowering-leadership-and-constructive-voice-a-sequential-mediation-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71223.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">304</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">1391</span> Contribution of Exchange-correlation Effects on Weakly Relativistic Plasma Expansion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Fermous">Rachid Fermous</a>, <a href="https://publications.waset.org/abstracts/search?q=Rima%20Mebrek"> Rima Mebrek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Plasma expansion is an important physical process that takes place in laser interactions with solid targets. Within a self-similar model for the hydrodynamic multi-fluid equations, we investigated the expansion of dense plasma. The weakly relativistic electrons are produced by ultra-intense laser pulses, while ions are supposed to be in a non-relativistic regime. It is shown that dense plasma expansion is found to be governed mainly by quantum contributions in the fluid equations that originate from the degenerate pressure in addition to the nonlinear contributions from exchange and correlation potentials. The quantum degeneracy parameter proﬁle provides clues to set the limit between under-dense and dense relativistic plasma expansions at a given density and temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plasma%20expansion" title="plasma expansion">plasma expansion</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20degeneracy" title=" quantum degeneracy"> quantum degeneracy</a>, <a href="https://publications.waset.org/abstracts/search?q=weakly%20relativistic" title=" weakly relativistic"> weakly relativistic</a>, <a href="https://publications.waset.org/abstracts/search?q=under-dense%20%20plasma" title=" under-dense plasma"> under-dense plasma</a> </p> <a href="https://publications.waset.org/abstracts/167933/contribution-of-exchange-correlation-effects-on-weakly-relativistic-plasma-expansion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167933.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">87</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">1390</span> Raising Awareness of Education for Sustainable Development Oriented School Programs and Curriculum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dina%20L.%20DiSantis">Dina L.

By offering programs such as the Japan-U.S. Teacher Exchange Program for Education for Sustainable Development (ESD); teachers from both countries become more aware of what ESD school programs and curricula are being implemented in both countries. Teachers gain a greater sense of global interconnectedness when they are given the opportunity to share in each other’s culture and life. The primary objectives of the program are to foster a mutual exchange between the teachers in the United States and Japan, to increase an understanding of culture and educational systems, to give teachers opportunities to collaborate on lessons and projects in areas of sustainability and to enhance professional development opportunities for both U.S and Japanese teachers. The two areas of focus for teachers, are food education and environmental education. Teachers from both countries collaborate and design curriculum and projects for their students in order to help them become more aware of the importance of global sustainability. An overview of the program and the results of an international collaborative project, encouraging local eating and forging a cultural connection to food will be presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=education%20for%20sustainable%20development" title="education for sustainable development">education for sustainable development</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20education" title=" environmental education"> environmental education</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20education" title=" food education"> food education</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20collaboration" title=" international collaboration"> international collaboration</a> </p> <a href="https://publications.waset.org/abstracts/84181/raising-awareness-of-education-for-sustainable-development-oriented-school-programs-and-curriculum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84181.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">161</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">1389</span> Corporate Social Responsibility and Its Impact on Corporate Governance: Comparative Study between Listed Companies on Bucharest and Bombay Stock Exchange</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Feleag%C4%83">L.

The efficiency of energy conversion in PEM fuel cells is dependent on the catalytic activities of the catalysts used in the cathode and anode of membrane electrode assemblies. Membrane is considered the heart of PEM fuel cells without which they cannot produce electricity. PEM fuel cell performance increased with coating carbon nanotube (CNT). CNT show a unique combination of stiffness, strength, and tenacity compared to other fiber materials which usually lack one or more of these properties. Two different experiments were performed and the membrane performance has been determined by repeating the two experiments that were done before coating. The purposes of these experiments are the observation of power change due to a temperature change in the same voltage value. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanotube%20%28CNT%29" title="carbon nanotube (CNT)">carbon nanotube (CNT)</a>, <a href="https://publications.waset.org/abstracts/search?q=proton%20exchange%20membrane%20%28PEM%29" title=" proton exchange membrane (PEM)"> proton exchange membrane (PEM)</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20cell" title=" fuel cell"> fuel cell</a>, <a href="https://publications.waset.org/abstracts/search?q=spin%20method" title=" spin method"> spin method</a> </p> <a href="https://publications.waset.org/abstracts/50261/experimental-investigation-of-the-effect-of-temperature-on-a-pem-fuel-cell-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50261.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">381</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">1387</span> An Analysis of Oil Price Changes and Other Factors Affecting Iranian Food Basket: A Panel Data Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Niloofar%20Ashktorab">Niloofar Ashktorab</a>, <a href="https://publications.waset.org/abstracts/search?q=Negar%20Ashktorab"> Negar Ashktorab</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Oil exports fund nearly half of Iran’s government expenditures, since many years other countries have been imposed different sanctions against Iran.

Numerous technical and economic benefits of low salinity polymer flooding (LSPF) have been reported. However, as with any EOR technology, there are various risks involved in using LSPF. Ions exchange between porous media and brine is one of the Crude oil/ brine/ rocks (COBR) reactions that is identified as a potential risk in LSPF. To the best of our knowledge, this conclusion was drawn based on bulk rheology measurements, and no explanation was provided on how water chemistry changed in the presence of polymer. Therefore, this study aimed to understand rock/ brine interactions with high and low salinity brine in the absence and presence of polymer with Omani reservoir core plugs. Many single-core flooding experiments were performed with low and high salinity polymer solutions to investigate the influence of partially hydrolyzed polyacrylic amide with different brine salinities on cation exchange reactions. Ion chromatography (IC), total organic carbon (TOC), rheological, and pH measurements were conducted for produced aqueous phase. A higher increase in pH and lower polymer adsorption was observed in LSPF compared with conventional polymer flooding. In addition, IC measurements showed that all produced fluids in the absence and presence of polymer showed elevated Ca²⁺, Mg²⁺, K+, Cl- and SO₄²⁻ ions compared to the injected fluids. However, the divalent cations levels, mainly Ca²⁺, were the highest and remained elevated for several pore volumes in the presence of LSP. The results are in line with rheological measurements where the highest viscosity reduction was recorded with the highest level of Ca²⁺ production. Despite the viscosity loss due to cation exchange reactions, LSP can be an attractive alternative to conventional polymer flooding in the Marmul field. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polymer" title="polymer">polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=ions" title=" ions"> ions</a>, <a href="https://publications.waset.org/abstracts/search?q=exchange" title=" exchange"> exchange</a>, <a href="https://publications.waset.org/abstracts/search?q=recovery" title=" recovery"> recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20salinity" title=" low salinity"> low salinity</a> </p> <a href="https://publications.waset.org/abstracts/149596/high-and-low-salinity-polymer-in-omani-oil-field" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149596.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">114</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1385</span> The Importance of Knowledge Innovation for External Audit on Anti-Corruption</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adel%20M.%20Qatawneh">Adel M.

Mg2+and Sr2+ ions concentrations were varied between (0.00-0.10), keeping concentration of SO42- ions at z=0.05. [Mg (NO3)2], [Sr (NO3)2] and (Na2SO4) were used as Mg2+, Sr2+, and SO42- sources respectively. The synthesized white precipitate were subjected to heat treatment at 500ºC and finally characterized by X-ray diffraction (XRD) and Fourier Transform infra-red spectroscopy (FTIR). The results showed that the substitution of Mg2+, Sr2+ and SO42- ions into the HA lattice resulted in an increase in the broadness and reduction of XRD peaks. This confirmed that the crystallinity was reduced due to the substitution of ions. Similarly, FTIR result showed the effect of substitution on phosphate bands as well as exchange of hydroxyl group by SO42- ions to balance the charges on HA surface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydroxyapatite" title="hydroxyapatite">hydroxyapatite</a>, <a href="https://publications.waset.org/abstracts/search?q=substitution" title=" substitution"> substitution</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization" title=" characterization"> characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=XRD" title=" XRD"> XRD</a>, <a href="https://publications.waset.org/abstracts/search?q=FTIR" title=" FTIR"> FTIR</a> </p> <a href="https://publications.waset.org/abstracts/14180/synthesis-and-characterization-of-magnesium-and-strontium-doped-sulphate-hydroxyapatite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14180.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">443</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">1383</span> The Impact of Vertical Product Differentiation on Exchange Rate Pass-Through: An Empirical Investigation of IRON and Steel Industry between Thailand and Vietnam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Santi%20Termprasertsakul">Santi Termprasertsakul</a>, <a href="https://publications.waset.org/abstracts/search?q=Jakkrich%20Jearviriyaboonya"> Jakkrich Jearviriyaboonya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper studies the market power and pricing behavior of products in iron and steel industry by investigating the impact of vertical product differentiation (VPD) on exchange rate pass-through (ERPT). Vietnam has become one of the major trading partners of Thailand since 2017. The iron and steel export value to Vietnam is more than $300 million a year. Particularly, the average growth rate of importing iron and steel is approximately 30% per year. The VPD is applied to analyze the quality difference of iron and steel between Thailand and Vietnam. The 20 products in iron and steel industry are investigated. The monthly pricing behavior of Harmonized Commodity Description and Coding System 4-digit products is observed from 2010 to 2019. The Nonlinear Autoregressive Distributed Lag is also used to analyze the asymmetry of ERPT in this paper. The empirical results basically reveal an incomplete pass-through between Thai Baht and Vietnamese Dong. The ERPT also varies with the degree of VPD. The product with higher VPD, indicating higher unit values, has higher ERPT. This result suggests the higher market power of the Thai iron and steel industry. In addition, the asymmetry of ERPT exists. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=exchange%20rate%20pass-through" title="exchange rate pass-through">exchange rate pass-through</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20and%20steel%20industry" title=" iron and steel industry"> iron and steel industry</a>, <a href="https://publications.waset.org/abstracts/search?q=pricing%20behavior" title=" pricing behavior"> pricing behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=vertical%20product%20differentiation" title=" vertical product differentiation"> vertical product differentiation</a> </p> <a href="https://publications.waset.org/abstracts/122212/the-impact-of-vertical-product-differentiation-on-exchange-rate-pass-through-an-empirical-investigation-of-iron-and-steel-industry-between-thailand-and-vietnam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122212.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">142</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">1382</span> An Econometric Analysis of the Impacts of Inflation on the Economic Growth of South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gisele%20Mah">Gisele Mah</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Saah"> Paul Saah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The rising rates of inflation are hindering economic growth in developing nations. Hence, this study investigated the effects of inflation rates on the economic growth of South Africa using the secondary time series data from 1987 to 2022. The main objectives of this study were to investigate the long run relationship between inflation and economic growth, and also to determine the causality direction between these two variables. The study utilized the Autoregressive Distributed Lag (ARDL) bounds test of co-integration to investigate whether there is a long-run relationship between inflation and economic growth. The Pairwise Granger causality approach was employed to determine the second objective, which is the direction of causality. The study discovered only one co-integration relationship between our variables and it was between inflation and economic growth. The results showed that there is a negative and significant relationship between inflation and economic growth. There appeared to be a positive and significant relationship between economic growth and exchange rate. The interest rates have shown to be negative and insignificant in explaining economic growth. The study also established that inflation does Granger cause economic growth which is given as GDP. Similarly, the study discovered that inflation Granger causes exchange rates. Therefore, the study recommends that inflation should be decreased in South Africa, in order for economic growth to increase. Contrary, this study recommends that South Africa should increase its exchange rates, in order for economic growth to also increase. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inflation%20rate" title="inflation rate">inflation rate</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20growth" title=" economic growth"> economic growth</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Africa" title=" South Africa"> South Africa</a>, <a href="https://publications.waset.org/abstracts/search?q=autoregressive%20distributed%20lag%20model" title=" autoregressive distributed lag model"> autoregressive distributed lag model</a> </p> <a href="https://publications.waset.org/abstracts/185947/an-econometric-analysis-of-the-impacts-of-inflation-on-the-economic-growth-of-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185947.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">48</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">1381</span> Batch and Dynamic Investigations on Magnesium Separation by Ion Exchange Adsorption: Performance and Cost Evaluation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20H.%20Sorour">Mohamed H.

Strong, weak and mixed types ion exchange systems could be designed and optimized for target separation. In this paper, different types of adsorbents comprising zeolite 13X and kaolin, in addition to, poly acrylate/zeolite (AZ), poly acrylate/kaolin (AK) and stand-alone poly acrylate (A) hydrogel types were prepared via microwave (M) and ultrasonic (U) irradiation techniques. They were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). The developed adsorbents were evaluated on bench scale level and based on assessment results, a composite bed has been formulated for performance evaluation in pilot scale column investigations. Owing to the hydrogel nature of the partially crosslinked poly acrylate, the developed adsorbents manifested a swelling capacity of about 50 g/g. The pilot trials have been carried out using magnesium enriched Red Seawater to simulate Red Seawater desalination brine. Batch studies indicated varying uptake efficiencies, where Mg adsorption decreases according to the following prepared hydrogel types AU>AM>AKM>AKU>AZM>AZU, being 108, 107, 78, 69, 66 and 63 mg/g, respectively. Composite bed adsorbent tested in the up-flow mode column studies indicated good performance for Mg uptake. For an operating cycle of 12 h, the maximum uptake during the loading cycle approached 92.5-100 mg/g, which is comparable to the performance of some commercial resins. Different regenerants have been explored to maximize regeneration and minimize the quantity of regenerants including 15% NaCl, 0.1 M HCl and sodium carbonate. Best results were obtained by acidified sodium chloride solution. In conclusion, developed cation exchange adsorbents comprising clay or zeolite support indicated adequate performance for Mg recovery under saline environment. Column design operated at the up-flow mode (approaching expanded bed) is appropriate for such type of separation. Preliminary cost indicators for Mg recovery via ion exchange have been developed and analyzed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=batch%20and%20dynamic%20magnesium%20separation" title="batch and dynamic magnesium separation">batch and dynamic magnesium separation</a>, <a href="https://publications.waset.org/abstracts/search?q=seawater" title=" seawater"> seawater</a>, <a href="https://publications.waset.org/abstracts/search?q=polyacrylate%20hydrogel" title=" polyacrylate hydrogel"> polyacrylate hydrogel</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20evaluation" title=" cost evaluation"> cost evaluation</a> </p> <a href="https://publications.waset.org/abstracts/99622/batch-and-dynamic-investigations-on-magnesium-separation-by-ion-exchange-adsorption-performance-and-cost-evaluation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99622.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">135</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">1380</span> Modified DNA as a Base Material for Nonlinear Optics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ewelina%20Nowak">Ewelina Nowak</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Wisla-Swider"> Anna Wisla-Swider</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Deoxyribonucleic acid (DNA) is a biomolecule which exhibits an electro-optic properties.

The linear gradient from pH 5.6 to pH 10.2 is generated over time by running a linear pump gradient from 100% Thermo Scientific™ CX-1 pH Gradient Buffer A (pH 5.6) to 100% CX-1 pH Gradient Buffer B (pH 10.2), using the Thermo Scientific™ Vanquish™ UHPLC system. Results: The pH gradient method is generally applicable to monoclonal antibody charge variant analysis. In conjunction with state-of-the-art column and UHPLC technology, ultra fast high-resolution separations are consistently achieved in under 5 minutes for all mAbs analyzed. Conclusion: The linear pH gradient method is a platform method for mAb charge variant analysis. The linear pH gradient method can be easily optimized to improve separations and shorten cycle times. Ultra-fast charge variant separation is facilitated with UHPLC that complements, and in some instances outperforms CE approaches in terms of both resolution and throughput. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=charge%20variants" title="charge variants">charge variants</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20exchange%20chromatography" title=" ion exchange chromatography"> ion exchange chromatography</a>, <a href="https://publications.waset.org/abstracts/search?q=monoclonal%20antibody" title=" monoclonal antibody"> monoclonal antibody</a>, <a href="https://publications.waset.org/abstracts/search?q=UHPLC" title=" UHPLC"> UHPLC</a> </p> <a href="https://publications.waset.org/abstracts/63884/ultra-fast-ph-gradient-ion-exchange-chromatography-for-the-separation-of-monoclonal-antibody-charge-variants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63884.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">440</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">1378</span> Energy Management of Hybrid Energy Source Composed of a Fuel Cell and Supercapacitor for an Electric Vehicle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mejri%20Achref">Mejri Achref</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes an energy management strategy for an electrical hybrid vehicle which is composed of a Proton Exchange Membrane (PEM) fuel cell and a supercapacitor storage device.

In the long-run the general price level and exchange rate have a positively significant effect on domestic output. The estimated result further revealed that fiscal stimulus help stimulate domestic output in the long-run, but not in the short-run, while monetary expansion help to stimulate output in both short-run and long-run. The result is complied with the theory which is the macroeconomic policies, fiscal and monetary policy; help to stimulate domestic output in the long-run. The estimated result of the Vector Error Correction Model (VECM) has indicated more clearly that the consumer price index has a positive effect on output with highly statistically significant. Increasing in the general price level would increase the competitiveness among producers than increase in the output. However, the exchange rate also has a positive effect and highly significant on the gross domestic product. The exchange rate depreciation might increase export since the purchasing power of foreigners has increased. More importantly, fiscal stimulus would help stimulate the domestic output in the long-run since the coefficient of government expenditure is positive. In addition, monetary expansion would also help stimulate the output and the result is highly significant. Thus, fiscal stimulus and monetary expansionary would help stimulate the domestic output in the long-run in Cambodia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fiscal%20policy" title="fiscal policy">fiscal policy</a>, <a href="https://publications.waset.org/abstracts/search?q=monetary%20policy" title=" monetary policy"> monetary policy</a>, <a href="https://publications.waset.org/abstracts/search?q=ARDL" title=" ARDL"> ARDL</a>, <a href="https://publications.waset.org/abstracts/search?q=VECM" title=" VECM"> VECM</a> </p> <a href="https://publications.waset.org/abstracts/22223/the-effect-of-macroeconomic-policies-on-cambodias-economy-ardl-and-vecm-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22223.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">1375</span> The Impact of Macroeconomic Factors on Tehran Stock Exchange Index during Economic and Oil Sanctions between January 2006 and December 2012</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Movahedizadeh">Hamed Movahedizadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Annuar%20Md%20Nassir"> Annuar Md Nassir</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Karimimalayer"> Mehdi Karimimalayer</a>, <a href="https://publications.waset.org/abstracts/search?q=Navid%20Samimi%20Sedeh"> Navid Samimi Sedeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Bagherpour"> Ehsan Bagherpour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this paper is to evaluate Tehran’s Stock Exchange (TSE) performance regarding with impact of four macroeconomic factors including world crude Oil Price (OP), World Gold Price (GP), Consumer Price Index (CPI) and total Supplied Oil by Iran (SO) from January 2006 to December 2012 that Iran faced with economic and oil sanctions. Iran's exports of crude oil and lease condensate reduced to roughly 1.5 million barrels per day (bbl/d) in 2012, compared to 2.5 million bbl/d in 2011 due to hard sanctions. Monthly data are collected and subjected to a battery of tests through ordinary least square by EViews7. This study found that gold price and oil price are positively correlated with stock returns while total oil supplied and consumer price index have negative relationship with stock index, however, consumer price index tends to become insignificant in stock index. While gold price and consumer price index have short run relationship with TSE index at 10% of significance level this amount for oil price is significant at 5% and there is no significant short run relationship between supplied oil and Tehran stock returns.

Replacing the traditional graphite plate with a stainless steel plate as a bipolar plate can greatly reduce the weight and volume of the stack, and has more cost advantages. However, the passivation layer on the surface of stainless steel makes the contact resistance reach the ohmic level and reduces the performance of the fuel cell. Therefore, it is necessary to reduce the interfacial contact resistance through the surface treatment. In this research, the thickness, uniformity, interfacial contact resistance (ICR), and adhesion of the carbon-based layer was analyzed. On the other hand, the effect of coating properties on the performance of the fuel cell was verified through I-V tests. The results show that after coating the contact resistance is greatly reduced by three stages to the microohm level, and as the film thickness is reduced, the contact resistance is reduced from 229~118 mΩ-cm² to 135~73 mΩ-cm² at a general assembly pressure of 1 to 2 MPa., and the current density at 0.6 V increased from 485.7 mA/cm² to 575.7 mA/cm². This study verifies the importance of the uniformity and ICR of the coating on proton exchange membrane fuel cell (PEMFC), and the surface coating technology is the key to affecting the characteristics of the coating. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contact%20resistance" title="contact resistance">contact resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=proton%20exchange%20membrane%20fuel%20cell" title=" proton exchange membrane fuel cell"> proton exchange membrane fuel cell</a>, <a href="https://publications.waset.org/abstracts/search?q=PEMFC" title=" PEMFC"> PEMFC</a>, <a href="https://publications.waset.org/abstracts/search?q=SS%20bipolar%20plate" title=" SS bipolar plate"> SS bipolar plate</a>, <a href="https://publications.waset.org/abstracts/search?q=spray%20coating%20process" title=" spray coating process"> spray coating process</a> </p> <a href="https://publications.waset.org/abstracts/125941/study-on-properties-of-carbon-based-layer-for-proton-exchange-membrane-fuel-cell-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125941.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">206</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">1373</span> Development of Partial Sulphonated Poly(Vinylidene Fluoride - Hexafluoro Propylene)–Montmorillonite Nano-Composites as Proton Exchange Membranes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Selvakumar">K.

The chosen variables of fiscal policy are government expenditure and net taxes on products, while the effect of monetary policy is presented by the inflation rate and the official exchange rate. From the results, we find that in the long-run, the impact of government expenditures is positive, while the effect of taxes is negative on growth. Additionally, we find that the inflation rate is found to have little effect on GDP per capita but the impact of the exchange rate is insignificant.

These activities are also known as the main contributor to the national greenhouse gas. In order to understand more about greenhouse gas exchange in these activities and to investigate the factors influencing carbon cycling and sequestration in these types of ecosystems, since 2019, the first eddy covariance station has been installed in a paddy field in Long An province, Mekong Delta. The station was equipped with state-of-the-art equipment for CO₂ and CH₄ gas exchange and micrometeorology measurements. In this study, data from the station was processed following the ICOS recommendations (Integrated Carbon Observation System) standards for CO₂, while CH₄ was manually processed and gap-filled using a random forest model from methane-gapfill-ml, a machine learning package, as there is no standard method for CH₄ flux gap-filling yet. Finally, the carbon equivalent (Ce) balance based on CO₂ and CH₄ fluxes was estimated. The results show that in 2020, even though a new water management practice - alternate wetting and drying - was applied to reduce methane emissions, the paddy field released 928 g Cₑ.m⁻².yr⁻¹, and in 2021, it was reduced to 707 g Cₑ.m⁻².yr⁻¹. On a provincial level, rice cultivation activities in Long An, with a total area of 498,293 ha, released 4.6 million tons of Cₑ in 2020 and 3.5 million tons of Cₑ in 2021. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eddy%20covariance" title="eddy covariance">eddy covariance</a>, <a href="https://publications.waset.org/abstracts/search?q=greenhouse%20gas" title=" greenhouse gas"> greenhouse gas</a>, <a href="https://publications.waset.org/abstracts/search?q=methane" title=" methane"> methane</a>, <a href="https://publications.waset.org/abstracts/search?q=rice%20cultivation" title=" rice cultivation"> rice cultivation</a>, <a href="https://publications.waset.org/abstracts/search?q=Mekong%20Delta" title=" Mekong Delta"> Mekong Delta</a> </p> <a href="https://publications.waset.org/abstracts/175768/measuring-greenhouse-gas-exchange-from-paddy-field-using-eddy-covariance-method-in-mekong-delta-vietnam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175768.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">142</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">1369</span> Cryptocurrencies: Business Students’ Awareness and Universities’ Adoption Readiness and Compatibility of Use Considering the Mediation of Attitudes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eric%20S.%20Parilla">Eric S.

The research used partial least squares structural equation modeling (PLS-SEM) and deployed a questionnaire attuned to the awareness and attitudes of business students towards cryptocurrencies and readiness and compatibility of use in universities and colleges in Ilocos Norte. The output of the investigation revealed that awareness of business students is not correlated to the readiness of universities and colleges, which means that even though students understand cryptocurrencies, it is not an assurance that universities and colleges are ready to accept them as the medium of exchange. The study proposes that training and seminars for business students and professionals should be conducted to expand understanding and acceptance of cryptocurrencies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryptocurrencies" title="cryptocurrencies">cryptocurrencies</a>, <a href="https://publications.waset.org/abstracts/search?q=awareness" title=" awareness"> awareness</a>, <a href="https://publications.waset.org/abstracts/search?q=readiness" title=" readiness"> readiness</a>, <a href="https://publications.waset.org/abstracts/search?q=attitudes" title=" attitudes"> attitudes</a> </p> <a href="https://publications.waset.org/abstracts/149449/cryptocurrencies-business-students-awareness-and-universities-adoption-readiness-and-compatibility-of-use-considering-the-mediation-of-attitudes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149449.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">225</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">1368</span> Importance of Knowledge in the Interdisciplinary Production Processes of Innovative Medical Tools</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katarzyna%20Mleczko">Katarzyna Mleczko</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Processes of production of innovative medical tools have interdisciplinary character. They consist of direct and indirect close cooperation of specialists of different scientific branches. The Knowledge they have seems to be important for undertaken design, construction and manufacturing processes. The Knowledge exchange between participants of these processes is therefore crucial for the final result, which are innovative medical products. The paper draws attention to the necessity of feedback from the end user to the designer / manufacturer of medical tools which will allow for more accurate understanding of user needs. The study describes prerequisites of production processes of innovative medical (surgical) tools including participants and category of knowledge resources occurring in these processes. They are the result of research in selected Polish organizations involved in the production of medical instruments and are the basis for further work on the development of knowledge sharing model in interdisciplinary teams geographically dispersed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interdisciplinary%20production%20processes" title="interdisciplinary production processes">interdisciplinary production processes</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20exchange" title=" knowledge exchange"> knowledge exchange</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20sharing" title=" knowledge sharing"> knowledge sharing</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20tools" title=" medical tools"> medical tools</a> </p> <a href="https://publications.waset.org/abstracts/44704/importance-of-knowledge-in-the-interdisciplinary-production-processes-of-innovative-medical-tools" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44704.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">442</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">1367</span> The Role of Short-Term Study Abroad Experience on Intercultural Communication Competence </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zeynep%20Aksoy">Zeynep Aksoy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Since global mobility of capital, information and people increase more and more, intercultural communication and management become a growing study field of investigating various aspects of the interaction between people from different cultural backgrounds. Human mobility, caused by several intentions from tourism to forced migration, often put people in facing communication barriers, issues or sometimes conflicts. This reality naturally enforces education institutions to develop international policies and programs for students in order to improve their intercultural experiences along with the educative objectives. Study-abroad programs, particularly the student exchanges in higher education provide an environment for participants to encounter with cultural differences. Therefore, international exchange programs (i.e. Erasmus Student Mobility, Global Exchange Program) are accepted to bring opportunities for intergroup contact, which may lead students to obtain new perspectives about the host culture, either in positive or negative ways, and new intercultural communication skills. This study aims to explore the role of short-term study abroad experience on intercultural communication competence with a qualitative approach. It attempts to reveal a comparative analysis, which is derived from two field studies conducted in Izmir (Turkey) and in Amsterdam (the Netherlands) in 2015 and 2016. They were both organized in two phases as pre-and-posttest to gain an insight into the changes (if any) in students’ attitudes and knowledge regarding the host culture, and their further motivations towards cross-cultural interactions. With this aim, focus group sessions and in-depth interviews have been taken place with participants at the beginning of their stay and at the end of the semester. The sample covers students mainly from Erasmus program (20 students in Izmir and 14 students in Amsterdam), and few from Global Exchange Program (5 students in Amsterdam). Data obtained from both studies were thematically analyzed and essential themes were identified within the framework of intercultural communication competence. <p
