A continuous biosorption process using indigenous red seaweed, Gracilaria corticata, was performed to remove cadmium from the potable water. The process was conducted under fixed conditions and the breakthrough curves were achieved for three consecutive sorption-desorption cycles. A modeling based on Artificial Neural Network (ANN) was employed to fit the experimental breakthrough data. In addition, a simplified semi empirical model, Thomas, was employed for this purpose. It was found that ANN well described the experimental data (R2>0.99) while the Thomas prediction were a bit less successful with R2>0.97. The adjusted design parameters using the nonlinear form of Thomas model was in a good agreement with the experimentally obtained ones. The results approve the capability of ANN to predict the cadmium concentration in potable water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ANN" title="ANN">ANN</a>, <a href="https://publications.waset.org/abstracts/search?q=biosorption" title=" biosorption"> biosorption</a>, <a href="https://publications.waset.org/abstracts/search?q=cadmium" title=" cadmium"> cadmium</a>, <a href="https://publications.waset.org/abstracts/search?q=packed-bed" title=" packed-bed"> packed-bed</a>, <a href="https://publications.waset.org/abstracts/search?q=potable%20water" title=" potable water"> potable water</a> </p> <a href="https://publications.waset.org/abstracts/19068/ann-modeling-for-cadmium-biosorption-from-potable-water-using-a-packed-bed-column-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19068.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">430</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">504</span> The One, the Many, and the Doctrine of Divine Simplicity: Variations on Simplicity in Essentialist and Existentialist Metaphysics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mark%20Wiebe">Mark Wiebe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the tasks contemporary analytic philosophers have focused on (e.g., Wolterstorff, Alston, Plantinga, Hasker, and Crisp) is the analysis of certain medieval metaphysical frameworks. This growing body of scholarship has helped clarify and prevent distorted readings of medieval and ancient writers. However, as scholars like Dolezal, Duby, and Brower have pointed out, these analyses have been incomplete or inaccurate in some instances, e.g., with regard to analogical speech or the doctrine of divine simplicity (DDS). Additionally, contributors to this work frequently express opposing claims or fail to note substantial differences between ancient and medieval thinkers. This is the case regarding the comparison between Thomas Aquinas and others. Anton Pegis and Étienne Gilson have argued along this line that Thomas’ metaphysical framework represents a fundamental shift. Gilson describes Thomas’ metaphysics as a turn from a form of “essentialism” to “existentialism.” One should argue that this shift distinguishes Thomas from many Analytic philosophers as well as from other classical defenders of the DDS. Moreover, many of the objections Analytic Philosophers make against Thomas presume the same metaphysical principles undergirding the above-mentioned form of essentialism. This weakens their force against Thomas’ positions. In order to demonstrate these claims, it will be helpful to consider Thomas’ metaphysical outlook alongside that of two other prominent figures: Augustine and Ockham. One area of their thinking which brings their differences to the surface has to do with how each relates to Platonic and Neo-Platonic thought. More specifically, it is illuminating to consider whether and how each distinguishes or conceives essence and existence. It is also useful to see how each approaches the Platonic conflicts between essence and individuality, unity and intelligibility. In both of these areas, Thomas stands out from Augustine and Ockham. Although Augustine and Ockham diverge in many ways, both ultimately identify being with particularity and pit particularity against both unity and intelligibility. Contrastingly, Thomas argues that being is distinct from and prior to essence. Being (i.e., Being in itself) rather than essence or form must therefore serve as the ground and ultimate principle for the existence of everything in which being and essence are distinct. Additionally, since change, movement, and addition improve and give definition to finite being, multitude and distinction are, therefore, principles of being rather than non-being. Consequently, each creature imitates and participates in God’s perfect Being in its own way; the perfection of each genus exists pre-eminently in God without being at odds with God’s simplicity, God has knowledge, power, and will, and these and the many other terms assigned to God refer truly to the being of God without being either meaningless or synonymous. The existentialist outlook at work in these claims distinguishes Thomas in a noteworthy way from his contemporaries and predecessors as much as it does from many of the analytic philosophers who have objected to his thought. This suggests that at least these kinds of objections do not apply to Thomas’ thought. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=theology" title="theology">theology</a>, <a href="https://publications.waset.org/abstracts/search?q=philosophy%20of%20religion" title=" philosophy of religion"> philosophy of religion</a>, <a href="https://publications.waset.org/abstracts/search?q=metaphysics" title=" metaphysics"> metaphysics</a>, <a href="https://publications.waset.org/abstracts/search?q=philosophy" title=" philosophy"> philosophy</a> </p> <a href="https://publications.waset.org/abstracts/166817/the-one-the-many-and-the-doctrine-of-divine-simplicity-variations-on-simplicity-in-essentialist-and-existentialist-metaphysics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166817.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">73</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">503</span> Controller Design Using GA for SMC Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Susy%20Thomas">Susy Thomas</a>, <a href="https://publications.waset.org/abstracts/search?q=Sajju%20Thomas"> Sajju Thomas</a>, <a href="https://publications.waset.org/abstracts/search?q=Varghese%20Vaidyan"> Varghese Vaidyan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper considers SMCs using linear feedback with switched gains and proposes a method which can minimize the pole perturbation.

There was an exploration in 25 points (on 15 sub) basin of Rio Piedras (Boy.) obtaining soil samples, to which geo-technical characterization was performed by laboratory tests. Thomas model has a physical characterization of the input area by only four parameters (a, b, c, d). Achieve measurable relationship between geo technical parameters and 4 values of hydro logical parameters helps to determine subsurface, underground and surface flow more agile manner. It is intended in this way to reach some solutions regarding limits initial model parameters on the basis of Thomas geo-technical characterization. In hydro geological models of rural watersheds, calibration is an important process in the characterization of the study area. This step can require a significant computational cost and time, especially if the initial values or parameters before calibration are outside of the geo-technical reality. A better approach in these initial values means optimization of these process through a geo-technical materials area, where is obtained an important approach to the study as in the starting range of variation for the calibration parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distributed%20hydrology" title="distributed hydrology">distributed hydrology</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrological%20and%20geotechnical%20characterization" title=" hydrological and geotechnical characterization"> hydrological and geotechnical characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=Iber%20model" title=" Iber model"> Iber model</a> </p> <a href="https://publications.waset.org/abstracts/12863/physical-characterization-of-a-watershed-for-correlation-with-parameters-of-thomas-hydrological-model-and-its-application-in-iber-hidrodinamic-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12863.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">522</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">501</span> Income-Consumption Relationships in Pakistan (1980-2011): A Cointegration Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Himayatullah%20Khan">Himayatullah Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Alena%20Fedorova"> Alena Fedorova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present paper analyses the income-consumption relationships in Pakistan using annual time series data from 1980-81 to 2010-1. The paper uses the Augmented Dickey-Fuller test to check the unit root and stationarity in these two time series. The paper finds that the two time series are nonstationary but stationary at their first difference levels. The Augmented Engle-Granger test and the Cointegrating Regression Durbin-Watson test imply that the two time series of consumption and income are cointegrated and that long-run marginal propensity to consume is 0.88 which is given by the estimated (static) equilibrium relation. The paper also used the error correction mechanism to find out to model dynamic relationship. The purpose of the ECM is to indicate the speed of adjustment from the short-run equilibrium to the long-run equilibrium state. The results show that MPC is equal to 0.93 and is highly significant. The coefficient of Engle-Granger residuals is negative but insignificant. Statistically, the equilibrium error term is zero, which suggests that consumption adjusts to changes in GDP in the same period. The short-run changes in GDP have a positive impact on short-run changes in consumption. The paper concludes that we may interpret 0.93 as the short-run MPC. The pair-wise Granger Causality test shows that both GDP and consumption Granger cause each other. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cointegrating%20regression" title="cointegrating regression">cointegrating regression</a>, <a href="https://publications.waset.org/abstracts/search?q=Augmented%20Dickey%20Fuller%20test" title=" Augmented Dickey Fuller test"> Augmented Dickey Fuller test</a>, <a href="https://publications.waset.org/abstracts/search?q=Augmented%20Engle-Granger%20test" title=" Augmented Engle-Granger test"> Augmented Engle-Granger test</a>, <a href="https://publications.waset.org/abstracts/search?q=Granger%20causality" title=" Granger causality"> Granger causality</a>, <a href="https://publications.waset.org/abstracts/search?q=error%20correction%20mechanism" title=" error correction mechanism"> error correction mechanism</a> </p> <a href="https://publications.waset.org/abstracts/13511/income-consumption-relationships-in-pakistan-1980-2011-a-cointegration-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13511.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">414</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">500</span> Aquinas Be Damned: Tension between Nothingness and Suffering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elizabeth%20Latham">Elizabeth Latham</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aquinas has long been revered by the Catholic Church as one of the greatest theologians of all time. His most well-known and widely respected theological work, the Summa Theologica has been referenced by countless members of the clergy in support of arguments for and about the existence of God. It is surprising, then, and important that one component in his ontological arguments seems to contradict a precept upheld by the Catechism, the Catholic Church’s comprehensive document detailing their theological positions and laws. In Summa Theologica, Thomas Aquinas argued that God’s eternal existence is both an observable and necessary quality. In the Catechism, the Catholic Church argues that souls in Hell are separated from God, and only souls in Heaven are like him. After introducing research on Philosophical Psychology and the natures of consciousness and pain, this paper comes to the conclusion that in order to reconcile the theology of the Catholic Church at large with that of Thomas Aquinas, one must somehow solve the following problem: if a soul must exist eternally to suffer eternally, it must be like God; and, if a soul is in Hell, it is completely separate from God and not like him at all. Thomas Aquinas deviates at this point from the current theological holdings of the Catholic Church, and this apparent discrepancy must be resolved if the Church hopes to use him going forward as a standard for natural theology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aquinas" title="aquinas">aquinas</a>, <a href="https://publications.waset.org/abstracts/search?q=catholic%20catechism" title=" catholic catechism"> catholic catechism</a>, <a href="https://publications.waset.org/abstracts/search?q=consciousness" title=" consciousness"> consciousness</a>, <a href="https://publications.waset.org/abstracts/search?q=philosophical%20psychology" title=" philosophical psychology"> philosophical psychology</a>, <a href="https://publications.waset.org/abstracts/search?q=summa%20theologica" title=" summa theologica"> summa theologica</a> </p> <a href="https://publications.waset.org/abstracts/111919/aquinas-be-damned-tension-between-nothingness-and-suffering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111919.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">211</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">499</span> Grief and Repenting: The Engaging Remembrance in Thomas Hardy’s ‘Poems of 1912-13’</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chih-Chun%20Tang">Chih-Chun Tang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nostalgia, to some people, may seem foolhardy in a way. However, nostalgia is a completely and intensely private but social, collective emotion. It has continuing consequence and outgrowth for our lives as social actions. It leads people to hunt and explore remembrance of persons and places of our past in an effort to confer meaning of persons and places of present. In the ‘Poems of 1912-13’ Thomas Hardy, a British poet, composed a series of poems after the unexpected death of his long-disaffected wife, Emma. The series interprets the cognitive and emotional concussion of Emma’s death on Hardy, concerning his mind and real visit to the landscape in Cornwall, England. Both spaces perform the author’s innermost in thought to his late wife and to the landscape. They present an apparent counterpart of the poet and his afflicted conscience. After Emma had died, Hardy carried her recollections alive by roaming about in the real visit and whimsical land (space) they once had drifted and meandered. This paper highlights the nostalgias and feds that seem endlessly to crop up. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Hardy" title="Thomas Hardy">Thomas Hardy</a>, <a href="https://publications.waset.org/abstracts/search?q=remembrance" title=" remembrance"> remembrance</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological" title=" psychological"> psychological</a>, <a href="https://publications.waset.org/abstracts/search?q=poems%201912-13" title=" poems 1912-13"> poems 1912-13</a>, <a href="https://publications.waset.org/abstracts/search?q=Fred%20Davis" title=" Fred Davis"> Fred Davis</a>, <a href="https://publications.waset.org/abstracts/search?q=nostalgia" title=" nostalgia"> nostalgia</a> </p> <a href="https://publications.waset.org/abstracts/57051/grief-and-repenting-the-engaging-remembrance-in-thomas-hardys-poems-of-1912-13" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57051.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">272</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">498</span> Virtual Schooling as a Collaboration between Public Schools and the Scientific Community</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomas%20A.%20Fuller">Thomas A. Fuller</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Over the past fifteen years, virtual schooling has been introduced and implemented in varying degrees throughout the public education system in the United States. It is possible in some states for students to voluntarily take all of their course load online, without ever having to step in a classroom. Experts foresee a dramatic rise in the number of courses taken online by public school students in the United States, with some predicting that by 2019 as many as 50% of public high school courses will be delivered online. This electronic delivery of public education offers tremendous potential to the scientific community because it calls for innovation and is funded by public school revenue. Public accountability provides a ready supply of statistical data for measuring the progress of virtual schools as they are implemented into the public school arena. This allows for a survey of the current use of virtual schooling through examination of past statistical data, as well as forecasting forward for future years based upon this past data. Virtual schooling is on the rise in the United States, but its growth has been tempered by practical problems of implementation. The greatest and best use of virtual schooling thus far has been to supplement the courses offered by public schools (e.g., offering unique language courses, elective courses, and games-based math and science courses). The weaknesses of virtual schooling lay in the problematic accountability in allowing students to take courses online at home and the lack of supportive infrastructure in the public school arena. Virtual schooling holds great promise for the public school education system in the United States, as well as the scientific community. Online courses allow students access to a much greater catalog of courses than is offered through classroom instruction in their local public school. This promising sector needs assistance from the scientific community in implementing new pedagogical methodologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=virtual%20schools" title="virtual schools">virtual schools</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20classroom" title=" online classroom"> online classroom</a>, <a href="https://publications.waset.org/abstracts/search?q=electronic%20delivery" title=" electronic delivery"> electronic delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=technological%20innovation" title=" technological innovation"> technological innovation</a> </p> <a href="https://publications.waset.org/abstracts/24383/virtual-schooling-as-a-collaboration-between-public-schools-and-the-scientific-community" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24383.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">383</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">497</span> An Exploration of Early Cinematic Technology (1890s-1920s) and Shifting Cinematic Styles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adam%20L.%20Miller">Adam L.

The present land use in the catchment area of the reservoir indicates high agricultural activities, fishing, as well as domestic and small scale industrial activities. To study and monitor the quality of surface and drinking water of the area, water samples were collected from the reservoir, treated water at the treatment plant and potable water at the consumer end in three seasons November - February (cold season), March - June (dry season) and July - September (rainy season). The samples were analyzed for physical and chemical parameters, pH, temperature, total dissolved solids (TDS), conductivity, turbidity, total hardness, suspended solids, total solids, colour, dissolved oxygen (DO), biological oxygen demand (BOD), chloride ion (Cl<sup>-</sup>) nitrite (NO<sub>2</sub><sup>-</sup>), nitrate (NO<sub>3</sub><sup>-</sup>), chemical oxygen demand (COD) and phosphate (PO<sub>4</sub><sup>3-</sup>). The higher values obtained in some parameters with respect to the acceptable standard set by World Health Organization (WHO) and Nigerian Industrial Standards (NIS) indicate the pollution of both the surface and drinking water. These pollutants were observed to have a negative impact on water quality in terms of eutrophication, largely due to anthropogenic activities in the watershed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=surface%20water" title="surface water">surface water</a>, <a href="https://publications.waset.org/abstracts/search?q=drinking%20water" title=" drinking water"> drinking water</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality"> water quality</a>, <a href="https://publications.waset.org/abstracts/search?q=pollution" title=" pollution"> pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20reservoir" title=" Thomas reservoir"> Thomas reservoir</a>, <a href="https://publications.waset.org/abstracts/search?q=Kano" title=" Kano"> Kano</a> </p> <a href="https://publications.waset.org/abstracts/53842/surface-and-drinking-water-quality-monitoring-of-thomas-reservoir-kano-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53842.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">295</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">495</span> Shock Compressibility of Iron Alloys Calculated in the Framework of Quantum-Statistical Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maxim%20A.%20Kadatskiy">Maxim A.

The Box-Behnen design (BBD) experimental results revealed the biosoprtion was maximum at pH 7.5, biosorbent dosage 0.1 g/L and initial CV concentration of 100 mg/L. The effect of various column parameters like bed depth (3, 6 and 9 cm), flow rate (5, 10 and 15 mL/min) and influent CV concentration (5, 10 and 15 mg/L) were investigated. The exhaustion time increased with increase of bed depth, influent CV concentration and decrease of flow rate. Adam-Bohart, Thomas and Yoon-Nelson models were used to predict the breakthrough curve and to evaluate the model parameters. Out of these models, Thomas and Yoon-Nelson models well described the experimental data.

In fact, this model provides the user with theoretical support for designing the lithium-ion battery parameters, such as the material particle or the diffusion coefficient adjustment direction. However, the model is mathematically complex as it is composed of several partial differential equations (PDEs) such as Fick’s law of diffusion, the MacInnes and Ohm’s equations, among other phenomena. Thus, to efficiently use the model in a time-domain simulation environment, the selection of the discretization technique is of a pivotal importance. There are several numerical methods available in the literature that can be used to carry out this task. In this study, a comparison between the explicit Euler, Crank-Nicolson, and Chebyshev discretization methods is proposed. These three methods are compared in terms of accuracy, stability, and computational times. Firstly, the explicit Euler discretization technique is analyzed. This method is straightforward to implement and is computationally fast. In this work, the accuracy of the method and its stability properties are shown for the electrolyte diffusion partial differential equation. Subsequently, the Crank-Nicolson method is considered. It represents a combination of the implicit and explicit Euler methods that has the advantage of being of the second order in time and is intrinsically stable, thus overcoming the disadvantages of the simpler Euler explicit method. As shown in the full paper, the Crank-Nicolson method provides accurate results when applied to the DFN model. Its stability does not depend on the integration time step, thus it is feasible for both short- and long-term tests. This last remark is particularly important as this discretization technique would allow the user to implement parameter estimation and optimization techniques such as system or genetic parameter identification methods using this model. Finally, the Chebyshev discretization technique is implemented in the DFN model. This discretization method features swift convergence properties and, as other spectral methods used to solve differential equations, achieves the same accuracy with a smaller number of discretization nodes. However, as shown in the literature, these methods are not suitable for handling sharp gradients, which are common during the first instants of the charge and discharge phases of the battery. The numerical results obtained and presented in this study aim to provide the guidelines on how to select the adequate discretization technique for the DFN model according to the type of application to be performed, highlighting the pros and cons of the three methods. Specifically, the non-eligibility of the simple Euler method for longterm tests will be presented. Afterwards, the Crank-Nicolson and the Chebyshev discretization methods will be compared in terms of accuracy and computational times under a wide range of battery operating scenarios. These include both long-term simulations for aging tests, and short- and mid-term battery charge/discharge cycles, typically relevant in battery applications like grid primary frequency and inertia control and electrical vehicle breaking and acceleration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Doyle-Fuller-Newman%20battery%20model" title="Doyle-Fuller-Newman battery model">Doyle-Fuller-Newman battery model</a>, <a href="https://publications.waset.org/abstracts/search?q=partial%20differential%20equations" title=" partial differential equations"> partial differential equations</a>, <a href="https://publications.waset.org/abstracts/search?q=discretization" title=" discretization"> discretization</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20methods" title=" numerical methods"> numerical methods</a> </p> <a href="https://publications.waset.org/abstracts/190331/a-comparison-between-different-discretization-techniques-for-the-doyle-fuller-newman-li-battery-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190331.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">23</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">491</span> Of Rites of Narration and Representation of Orient and Occident in Thomas Heywood's Fair Maid of the West</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tarik%20Bouguerba">Tarik Bouguerba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Thomas Heywood was an outstanding, prolific playwright of the period, writing both in prose and verse. Unlike Shakespeare in particular, Heywood could be considered as a playwright who was well informed about Morocco and wrote in greater detail about a possible dialogue among cultures. As it is a historical platform for power relations, The Fair Maid of the West recalled the heroism and excitement of English counterattacks against Spain in the Post-Armada period. This paper therefore pins down the acts of narration and representation of Morocco and Moroccans and examines how the Occident has contributed to the production of the Orient and finally attests to the metamorphosis the plot undergoes in Part I and Part II. As an adventure play, The Fair Maid of the West teaches about, informs of and confirms the existing patterns of virtue in European voyagers and at the same time it asserts how honor and chastity are European par excellence whereas villainy and wickedness are Oriental assets. Once taken captive, these virtues and traits are put into task as the plot disentangles. This paper also examines how the play in both parts generates a whole history of stereotypes about Morocco and unexpectedly subverts this stereotype; such a biased mode of narration of the Orient the playwright took up at first was played down at a later phase in the narrative. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Heywood" title="Heywood">Heywood</a>, <a href="https://publications.waset.org/abstracts/search?q=Occident" title=" Occident"> Occident</a>, <a href="https://publications.waset.org/abstracts/search?q=Orientalism" title=" Orientalism"> Orientalism</a>, <a href="https://publications.waset.org/abstracts/search?q=Stereotype" title=" Stereotype"> Stereotype</a>, <a href="https://publications.waset.org/abstracts/search?q=Virtue" title=" Virtue"> Virtue</a> </p> <a href="https://publications.waset.org/abstracts/136508/of-rites-of-narration-and-representation-of-orient-and-occident-in-thomas-heywoods-fair-maid-of-the-west" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136508.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">139</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">490</span> Between an Idea and the Experiment: Dome Houses in Warsaw</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zagu%C5%82a%20Artur">Zaguła Artur</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaruga-rozdolska%20Anna"> Jaruga-rozdolska Anna</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The idea of prefabricated dwellings dates back to the earliest times; however, it was during the modern era that it became one of the main thoughts that stimulated the imagination of architects. The system of prefabrication invented by Ford had inspired them to try to create a system or prototype that could become the basis for the mass 'production' of houses. The attempts made by Le Corbusier, Buckminster Fuller or Charles and Ray Eames, among others, are well known in this regard. The economic attractiveness of replicable, mass-producible houses meant that experiments in this area were undertaken in both the West and the East.

There has been a growing interest in the study of magnetic, electrical and structural properties of mixed ferrites. In the present work, structural and magnetic properties of Nickel and Calcium substituted Fe₃O₄ nanoparticles were investigated. NiₓCa₁₋ₓFe₂O₄ nanoparticles (x = 0, 0.1, 0.3, 0.5, 0.7, 0.9) were synthesized by chemical co-precipitation method and the samples were subsequently sintered at 900°C. The magnetic and structural properties of NiₓCa₁₋ₓFe₂O₄ were investigated using Vibrating Sample Magnetometer and X-Ray diffraction. The XRD results revealed that the synthesized particles have nanometer size and it varies from 46-72 nm as the calcium concentration diminishes. The variation is explained based on the increase in the reaction rate with Ni concentration which favors the formation of ultrafine particles of mixed ferrites. VSM results show pure CaFe₂O₄ exhibit paramagnetic behavior with low saturation value. As the concentration of Ca decreases, a transition occurs from paramagnetic state to ferromagnetic state. When the concentration of Ni becomes dominant, magnetic saturation, coercivity, and retentivity become high, indicating near ferromagnetic behavior of the compound. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=co-precipitation" title="co-precipitation">co-precipitation</a>, <a href="https://publications.waset.org/abstracts/search?q=ferrites" title=" ferrites"> ferrites</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20behavior" title=" magnetic behavior"> magnetic behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=structure" title=" structure"> structure</a> </p> <a href="https://publications.waset.org/abstracts/79188/structural-and-magnetic-properties-of-calcium-mixed-ferrites-prepared-by-co-precipitation-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79188.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">249</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">488</span> Forecasting the Volatility of Geophysical Time Series with Stochastic Volatility Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20C.%20Mariani">Maria C.

In this study, the volatility is defined as a logarithmic first-order autoregressive process. We observe that the inclusion of log-volatility into the time-varying parameter estimation significantly improves forecasting which is facilitated via maximum likelihood estimation. This allows us to conclude that the estimation algorithm for the corresponding one-step-ahead suggested volatility (with ±2 standard prediction errors) is very feasible since it possesses good convergence properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Augmented%20Dickey%20Fuller%20Test" title="Augmented Dickey Fuller Test">Augmented Dickey Fuller Test</a>, <a href="https://publications.waset.org/abstracts/search?q=geophysical%20time%20series" title=" geophysical time series"> geophysical time series</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20likelihood%20estimation" title=" maximum likelihood estimation"> maximum likelihood estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=stochastic%20volatility%20model" title=" stochastic volatility model"> stochastic volatility model</a> </p> <a href="https://publications.waset.org/abstracts/75110/forecasting-the-volatility-of-geophysical-time-series-with-stochastic-volatility-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75110.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">315</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">487</span> Continuous Fixed Bed Reactor Application for Decolourization of Textile Effluent by Adsorption on NaOH Treated Eggshell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Chafi">M.

Various low cost adsorbents have been studied for their applicability in treatment of different types of effluents. In this work, the intention of the study was to explore the efficacy and feasibility for azo dye, Acid Orange 7 (AO7) adsorption onto fixed bed column of NaOH Treated eggshell (TES). The effect of various parameters like flow rate, initial dye concentration, and bed height were exploited in this study. The studies confirmed that the breakthrough curves were dependent on flow rate, initial dye concentration solution of AO7 and bed depth. The Thomas, Yoon–Nelson, and Adams and Bohart models were analysed to evaluate the column adsorption performance. The adsorption capacity, rate constant and correlation coefficient associated to each model for column adsorption was calculated and mentioned. The column experimental data were fitted well with Thomas model with coefficients of correlation R2 ≥0.93 at different conditions but the Yoon–Nelson, BDST and Bohart–Adams model (R2=0.911), predicted poor performance of fixed-bed column. The (TES) was shown to be suitable adsorbent for adsorption of AO7 using fixed-bed adsorption column. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption%20models" title="adsorption models">adsorption models</a>, <a href="https://publications.waset.org/abstracts/search?q=acid%20orange%207" title=" acid orange 7"> acid orange 7</a>, <a href="https://publications.waset.org/abstracts/search?q=bed%20depth" title=" bed depth"> bed depth</a>, <a href="https://publications.waset.org/abstracts/search?q=breakthrough" title=" breakthrough"> breakthrough</a>, <a href="https://publications.waset.org/abstracts/search?q=dye%20adsorption" title=" dye adsorption"> dye adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=fixed-bed%20column" title=" fixed-bed column"> fixed-bed column</a>, <a href="https://publications.waset.org/abstracts/search?q=treated%20eggshell" title=" treated eggshell"> treated eggshell</a> </p> <a href="https://publications.waset.org/abstracts/43408/continuous-fixed-bed-reactor-application-for-decolourization-of-textile-effluent-by-adsorption-on-naoh-treated-eggshell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43408.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">377</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">486</span> The Impact of Distributed Epistemologies on Software Engineering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Smith">Thomas Smith</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many hackers worldwide would agree that, had it not been for linear-time theory, the refinement of Byzantine fault tolerance might never have occurred.

Standard I(0)/I(1) methods such as Augmented Dickey-Fuller (ADF), Philips-Perron (PP) and Kwiatkowski–Phillips–Schmidt–Shin (KPSS) tests were also employed. Our findings indicate that long memory exists in the CPI inflation rates of both countries. After processing fractional differencing and determining the short memory components, the models were specified as ARFIMA (4,0.35,2) and ARFIMA (3,0.49,3) respectively for Ghana and South Africa. Consequently, the CPI inflation rates of both countries are fractionally integrated and mean reverting. The implication of this result will assist in policy formulation and identification of inflationary pressures in an economy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Consumer%20Price%20Index%20%28CPI%29%20inflation%20rates" title="Consumer Price Index (CPI) inflation rates">Consumer Price Index (CPI) inflation rates</a>, <a href="https://publications.waset.org/abstracts/search?q=Whittle%20method" title=" Whittle method"> Whittle method</a>, <a href="https://publications.waset.org/abstracts/search?q=long%20memory" title=" long memory"> long memory</a>, <a href="https://publications.waset.org/abstracts/search?q=ARFIMA%20model" title=" ARFIMA model"> ARFIMA model</a> </p> <a href="https://publications.waset.org/abstracts/46099/long-memory-and-arfima-modelling-the-case-of-cpi-inflation-for-ghana-and-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46099.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">482</span> Microbial Reduction of Terpenes from Pine Wood Material</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bernhard%20Widhalm">Bernhard Widhalm</a>, <a href="https://publications.waset.org/abstracts/search?q=Cornelia%20Rieder-Gradinger"> Cornelia Rieder-Gradinger</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Ters"> Thomas Ters</a>, <a href="https://publications.waset.org/abstracts/search?q=Ewald%20Srebotnik"> Ewald Srebotnik</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Kuncinger"> Thomas Kuncinger</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Terpenes are natural components in softwoods and rank among the most frequently emitted volatile organic compounds (VOC) in the wood-processing industry. In this study, the main focus was on α- and β-pinene as well as Δ3-carene, which are the major terpenes in softwoods. To lower the total emission level of wood composites, defined terpene degrading microorganisms were applied to basic raw materials (e.g. pine wood particles and strands) in an optimised and industry-compatible testing procedure. In preliminary laboratory tests, bacterial species suitable for the utilisation of α-pinene as single carbon source in liquid culture were selected and then subjected to wood material inoculation. The two species Pseudomonas putida and Pseudomonas fluorescens were inoculated onto wood particles and strands and incubated at room temperature. Applying specific pre-cultivation and daily ventilation of the samples enabled a reduction of incubation time from six days to one day. SPME measurements and subsequent GC-MS analysis indicated a complete absence of α- and β-pinene emissions after 24 hours from pine wood particles. When using pine wood strands rather than particles, bacterial treatment resulted in a reduction of α- and β-pinene by 50%, while Δ3-carene emissions were reduced by 30% in comparison to untreated strands. Other terpenes were also reduced in the course of the microbial treatment. The method developed here appears to be feasible for industrial application. However, growth parameters such as time and temperature as well as the technical implementation of the inoculation step will have to be adapted for the production process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GC-MS" title="GC-MS">GC-MS</a>, <a href="https://publications.waset.org/abstracts/search?q=pseudomonas" title=" pseudomonas"> pseudomonas</a>, <a href="https://publications.waset.org/abstracts/search?q=SPME" title=" SPME"> SPME</a>, <a href="https://publications.waset.org/abstracts/search?q=terpenes" title=" terpenes"> terpenes</a> </p> <a href="https://publications.waset.org/abstracts/48124/microbial-reduction-of-terpenes-from-pine-wood-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48124.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">347</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">481</span> Performance of the Aptima® HIV-1 Quant Dx Assay on the Panther System </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siobhan%20O%E2%80%99Shea">Siobhan O’Shea</a>, <a href="https://publications.waset.org/abstracts/search?q=Sangeetha%20Vijaysri%20Nair"> Sangeetha Vijaysri Nair</a>, <a href="https://publications.waset.org/abstracts/search?q=Hee%20Cheol%20Kim"> Hee Cheol Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20Thomas%20Nugent"> Charles Thomas Nugent</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheuk%20Yan%20William%20Tong"> Cheuk Yan William Tong</a>, <a href="https://publications.waset.org/abstracts/search?q=Sam%20Douthwaite"> Sam Douthwaite</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Worlock"> Andrew Worlock</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Aptima® HIV-1 Quant Dx Assay is a fully automated assay on the Panther system. It is based on Transcription-Mediated Amplification and real time detection technologies. This assay is intended for monitoring HIV-1 viral load in plasma specimens and for the detection of HIV-1 in plasma and serum specimens. Nine-hundred and seventy nine specimens selected at random from routine testing at St Thomas’ Hospital, London were anonymised and used to compare the performance of the Aptima HIV-1 Quant Dx assay and Roche COBAS® AmpliPrep/COBAS® TaqMan® HIV-1 Test, v2.0. Two-hundred and thirty four specimens gave quantitative HIV-1 viral load results in both assays. The quantitative results reported by the Aptima Assay were comparable those reported by the Roche COBAS AmpliPrep/COBAS TaqMan HIV-1 Test, v2.0 with a linear regression slope of 1.04 and an intercept on -0.097. The Aptima assay detected HIV-1 in more samples than the Roche assay. This was not due to lack of specificity of the Aptima assay because this assay gave 99.83% specificity on testing plasma specimens from 600 HIV-1 negative individuals. To understand the reason for this higher detection rate a side-by-side comparison of low level panels made from the HIV-1 3rd international standard (NIBSC10/152) and clinical samples of various subtypes were tested in both assays. The Aptima assay was more sensitive than the Roche assay. The good sensitivity, specificity and agreement with other commercial assays make the HIV-1 Quant Dx Assay appropriate for both viral load monitoring and detection of HIV-1 infections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HIV%20viral%20load" title="HIV viral load">HIV viral load</a>, <a href="https://publications.waset.org/abstracts/search?q=Aptima" title=" Aptima"> Aptima</a>, <a href="https://publications.waset.org/abstracts/search?q=Roche" title=" Roche"> Roche</a>, <a href="https://publications.waset.org/abstracts/search?q=Panther%20system" title=" Panther system"> Panther system</a> </p> <a href="https://publications.waset.org/abstracts/21163/performance-of-the-aptima-hiv-1-quant-dx-assay-on-the-panther-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21163.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">375</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">480</span> Comparison of Adsorbents for Ammonia Removal from Mining Wastewater</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Al-Sheikh">F.

Elkamel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ammonia in mining wastewater is a significant problem, and treatment can be especially difficult in cold climates where biological treatment is not feasible. An adsorption process is one of the alternative processes that can be used to reduce ammonia concentrations to acceptable limits, and therefore a LEWATIT resin strongly acidic H+ form ion exchange resin and a Bowie Chabazite Na form AZLB-Na zeolite were tested to assess their effectiveness. For these adsorption tests, two packed bed columns (a mini-column constructed from a 32-cm long x 1-cm diameter piece of glass tubing, and a 60-cm long x 2.5-cm diameter Ace Glass chromatography column) were used containing varying quantities of the adsorbents. A mining wastewater with ammonia concentrations of 22.7 mg/L was fed through the columns at controlled flowrates. In the experimental work, maximum capacities of the LEWATIT ion exchange resin were 0.438, 0.448, and 1.472 mg/g for 3, 6, and 9 g respectively in a mini column and 1.739 mg/g for 141.5 g in a larger Ace column while the capacities for the AZLB-Na zeolite were 0.424, and 0.784 mg/g for 3, and 6 g respectively in the mini column and 1.1636 mg/g for 38.5 g in the Ace column. In the theoretical work, Thomas, Adams-Bohart, and Yoon-Nelson models were constructed to describe a breakthrough curve of the adsorption process and find the constants of the above-mentioned models. In the regeneration tests, 5% hydrochloric acid, HCl (v/v) and 10% sodium hydroxide, NaOH (w/v) were used to regenerate the LEWATIT resin and AZLB-Na zeolite with 44 and 63.8% recovery, respectively. In conclusion, continuous flow adsorption using a LEWATIT ion exchange resin and an AZLB-Na zeolite is efficient when using a co-flow technique for removal of the ammonia from wastewater. Thomas, Adams-Bohart, and Yoon-Nelson models satisfactorily fit the data with R<sup>2</sup> closer to 1 in all cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AZLB-Na%20zeolite" title="AZLB-Na zeolite">AZLB-Na zeolite</a>, <a href="https://publications.waset.org/abstracts/search?q=continuous%20adsorption" title=" continuous adsorption"> continuous adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=Lewatit%20resin" title=" Lewatit resin"> Lewatit resin</a>, <a href="https://publications.waset.org/abstracts/search?q=models" title=" models"> models</a>, <a href="https://publications.waset.org/abstracts/search?q=regeneration" title=" regeneration"> regeneration</a> </p> <a href="https://publications.waset.org/abstracts/78618/comparison-of-adsorbents-for-ammonia-removal-from-mining-wastewater" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78618.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">389</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">479</span> Excited State Structural Dynamics of Retinal Isomerization Revealed by a Femtosecond X-Ray Laser </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Przemyslaw%20Nogly">Przemyslaw Nogly</a>, <a href="https://publications.waset.org/abstracts/search?q=Tobias%20Weinert"> Tobias Weinert</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20James"> Daniel James</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergio%20Carbajo"> Sergio Carbajo</a>, <a href="https://publications.waset.org/abstracts/search?q=Dmitry%20Ozerov"> Dmitry Ozerov</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonia%20Furrer"> Antonia Furrer</a>, <a href="https://publications.waset.org/abstracts/search?q=Dardan%20Gashi"> Dardan Gashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Veniamin%20Borin"> Veniamin Borin</a>, <a href="https://publications.waset.org/abstracts/search?q=Petr%20Skopintsev"> Petr Skopintsev</a>, <a href="https://publications.waset.org/abstracts/search?q=Kathrin%20Jaeger"> Kathrin Jaeger</a>, <a href="https://publications.waset.org/abstracts/search?q=Karol%20Nass"> Karol Nass</a>, <a href="https://publications.waset.org/abstracts/search?q=Petra%20Bath"> Petra Bath</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Bosman"> Robert Bosman</a>, <a href="https://publications.waset.org/abstracts/search?q=Jason%20Koglin"> Jason Koglin</a>, <a href="https://publications.waset.org/abstracts/search?q=Matthew%20Seaberg"> Matthew Seaberg</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Lane"> Thomas Lane</a>, <a href="https://publications.waset.org/abstracts/search?q=Demet%20Kekilli"> Demet Kekilli</a>, <a href="https://publications.waset.org/abstracts/search?q=Steffen%20Br%C3%BCnle"> Steffen Brünle</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomoyuki%20Tanaka"> Tomoyuki Tanaka</a>, <a href="https://publications.waset.org/abstracts/search?q=Wenting%20Wu"> Wenting Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Christopher%20Milne"> Christopher Milne</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20A.%20White"> Thomas A.

We studied the sub-picosecond structural dynamics of retinal isomerization in the light-driven proton pump bacteriorhodopsin using an X-ray laser. Twenty snapshots with near-atomic spatial and temporal resolution in the femtosecond regime show how the excited all-trans retinal samples conformational states within the protein binding pocket prior to passing through a highly-twisted geometry and emerging in the 13-cis conformation. The aspartic acid residues and functional water molecules in proximity of the retinal Schiff base respond collectively to formation and decay of the initial excited state and retinal isomerization. These observations reveal how the protein scaffold guides this remarkably efficient photochemical reaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacteriorhodopsin" title="bacteriorhodopsin">bacteriorhodopsin</a>, <a href="https://publications.waset.org/abstracts/search?q=free-electron%20laser" title=" free-electron laser"> free-electron laser</a>, <a href="https://publications.waset.org/abstracts/search?q=retinal%20isomerization%20mechanism" title=" retinal isomerization mechanism"> retinal isomerization mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=time-resolved%20crystallography" title=" time-resolved crystallography"> time-resolved crystallography</a> </p> <a href="https://publications.waset.org/abstracts/90555/excited-state-structural-dynamics-of-retinal-isomerization-revealed-by-a-femtosecond-x-ray-laser" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90555.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">478</span> A Study of Islamic Stock Indices and Macroeconomic Variables</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Irfan">Mohammad Irfan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this paper is to investigate the relationship among the key macroeconomic variables and Islamic stock market in India. This study is based on the time series data of financial years 2009-2015 to explore the consistency of relationship between macroeconomic variables and Shariah Indices. The ADF (Augmented Dickey–Fuller Test Statistic) and PP (Phillips–Perron Test Statistic) tests are employed to check stationarity of the data. The study depicts the long run relationship between Shariah indices and macroeconomic variables by using the Johansen Co-integration test. BSE Shariah and Nifty Shariah have uni-direct Granger causality. The outcome of VECM is significantly confirming the applicability of best fitted model. Thus, Islamic stock indices are proficiently working for the development of Indian economy. It suggests that by keeping eyes on Islamic stock market which will be more interactive in the future with other macroeconomic variables. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Indian%20Shariah%20Indices" title="Indian Shariah Indices">Indian Shariah Indices</a>, <a href="https://publications.waset.org/abstracts/search?q=macroeconomic%20variables" title=" macroeconomic variables"> macroeconomic variables</a>, <a href="https://publications.waset.org/abstracts/search?q=co-integration" title=" co-integration"> co-integration</a>, <a href="https://publications.waset.org/abstracts/search?q=Granger%20causality" title=" Granger causality"> Granger causality</a>, <a href="https://publications.waset.org/abstracts/search?q=vector%20error%20correction%20model%20%28VECM%29" title=" vector error correction model (VECM)"> vector error correction model (VECM)</a> </p> <a href="https://publications.waset.org/abstracts/48403/a-study-of-islamic-stock-indices-and-macroeconomic-variables" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48403.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">279</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">477</span> The Quest for Palestinian Identity throughout Zayyad's Poetry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saleem%20Abu%20Jaber">Saleem Abu Jaber</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Igbaria"> Khaled Igbaria</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tawfiq Zayyad was born in Nazareth in 1929 and died in 1994. He was a prominent Palestinian poet, writer, scholar and politician. He had participated in the Palestinian political life not only as a poet and writer but also as a mayor of Nazareth as well as a member of the Israeli Knesset. All of the above confirms not only that it is worthy to investigate deeply and academically Palestinian commitment and identity throughout poems of the poet, but also that the poet deserves to include him within the top significant Arab Palestinian poets in despite of his being Israeli citizen. This paper studies to what extent the poet was committed to the Palestinian goals and agenda throughout poetry as well as to explore the ways and techniques in which the poet employed poetry in order to explore the Palestinian belonging and identification of the Palestinians in Israel. Methodologically, this paper will literary analyze some considerable poems of the poet looking in-depth critically and objectively. Moreover, this article relies on several poems of the poet because they are much relevant to the aimed discussion. By addressing both commitment and identity, this article hopes to contribute to a fuller understanding of Palestinian poets of 1960s to 2000s. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tawfiq%20Zayyad" title="Tawfiq Zayyad">Tawfiq Zayyad</a>, <a href="https://publications.waset.org/abstracts/search?q=Palestinian%20poetry" title=" Palestinian poetry"> Palestinian poetry</a>, <a href="https://publications.waset.org/abstracts/search?q=poetic%20commitment" title=" poetic commitment"> poetic commitment</a>, <a href="https://publications.waset.org/abstracts/search?q=poetic%20techniques" title=" poetic techniques"> poetic techniques</a> </p> <a href="https://publications.waset.org/abstracts/90126/the-quest-for-palestinian-identity-throughout-zayyads-poetry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90126.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">163</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">476</span> Compressive Stresses near Crack Tip Induced by Thermo-Electric Field</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Jin-Chee%20Liu">Thomas Jin-Chee Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the thermo-electro-structural coupled-field in a cracked metal plate is studied using the finite element analysis.
