nephropathy (CIN) or contrast-induced acute kidney injury (CI-AKI) is an unknown acute kidney injury (AKI) occurring after exposure to contrast media (CM). Contrast agents are most often used for diagnostic procedures or therapeutic angiographic interventions. Recently, Na/K citrate as a urine alkalinization has been evaluated for the prevention of CIN. We conducted this experiment to evaluate the efficiency of Na/K citrate on CIN in high-risk patients treated with cardiac catheterization. Methods: A prospective randomized clinical trial was conducted on 400 patients having moderate to high-risk factors for CIN treated with elective percutaneous coronary intervention (PCI) and were assigned randomly to the control group or the Na/K citrate group. The Na/K citrate group (n=200) received 5 g Na/K citrate solution, which was diluted in 200 mL water two h before and four hours after the first administration and intravenous hydration for two h prior to and six h after the procedure, while the control group (n=200) only received intravenous hydration. Serum creatinine (SCr) was calculated prior to the contrast exposure and after 48 h. CIN was described as a 25% increase in creatinine of serum (SCr) or >0.5 mg/dl 48 h after contrast administration. Results: CIN was observed in 33 patients (16.5%) in the control group and in 6 patients (3%) in the Na/K citrate group. A significant variation was recorded in the CIN incidence between the two groups 48 h after the radiocontrast agent administration (p < 0.001). Conclusion: Our results show that Na/K citrate is useful and substantially reduces the incidence of CIN. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contrast%20media" title="contrast media">contrast media</a>, <a href="https://publications.waset.org/abstracts/search?q=citrate" title=" citrate"> citrate</a>, <a href="https://publications.waset.org/abstracts/search?q=PCI" title=" PCI"> PCI</a> </p> <a href="https://publications.waset.org/abstracts/159055/prospective-randomized-trial-of-nak-citrate-for-the-prevention-of-contrast-induced-nephropathy-in-high-risk-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159055.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">104</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">46</span> Buckling Analysis of 2D Frames Using the Modified Newmark Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Amin%20Vakili">Seyed Amin Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahar%20Sadat%20Vakili"> Sahar Sadat Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Ehsan%20Vakili"> Seyed Ehsan Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Nader%20Abdoli%20Yazdi"> Nader Abdoli Yazdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main purpose of this paper is to present the Modified Newmark Method of buckling analysis frame considering the effect of the axial load.

The objective of this study is to verify the ability of the Modified Newmark Method to include geometric non-linearity in addition to non-linearity due to cracking, and also to show the advantage of the established method to reconsider an ignored minor parameter in mathematical modeling, such as the effect of the cracking by extra geometric bending moment Ny on cross-section properties. The purpose of this investigation is not to present some new results for the instability of reinforced or composite concrete columns. Therefore, no kinds of non-linearity involved in the problem are considered here. Only as mentioned, it is a part of the verification of the new established method to solve two kinds of non-linearity P- δ effect and cracking together simultaneously. However, the Modified Newmark Method can be used to solve non-linearity of materials and time-dependent behavior of concrete. However, since it is out of the scope of this article, it is not considered. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stability" title="stability">stability</a>, <a href="https://publications.waset.org/abstracts/search?q=buckling" title=" buckling"> buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20newmark%20method" title=" modified newmark method"> modified newmark method</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced" title=" reinforced"> reinforced</a> </p> <a href="https://publications.waset.org/abstracts/42634/stability-of-composite-struts-using-the-modified-newmark-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42634.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">333</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">44</span> Investigating Elastica and Post Buckling Behavior Columns Using the Modified Newmark Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Amin%20Vakili">Seyed Amin Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahar%20Sadat%20Vakili"> Sahar Sadat Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Ehsan%20Vakili"> Seyed Ehsan Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Nader%20Abdoli%20Yazdi"> Nader Abdoli Yazdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this article is to analyze the finite displacement of Columns by applying the Modified Newmark Method. This research will be performed on Columns subjected to compressive axial load, therefore the non-linearity of the geometry is also considered. If the considered strut is perfect, the governing differential equation contains a branching point in the solution path. Investigation into the Elastica is a part of generalizing the developed method. It presents the ability of the Modified Newmark Method in treating non-linear differential equations Derived from elastic strut stability problems. These include not only an approximate polynomial solution for the Elastica problems, but can also recognize the branching point and the stable solution.

The discussion will be restricted to plane frameworks containing a constant cross-section for each element. In addition, it is assumed that the frames are prevented from out-of-plane deflection. This part of the investigation is performed to generalize the established method for the assemblage structures such as frameworks. As explained, the governing differential equations are non-linear and cannot be formulated easily due to unknown axial load of the struts in the frame. By the assumption of constant axial load, the governing equations are changed to linear ones in most methods. Since the modeling and the solutions of the non-linear form of the governing equations are cumbersome, the linear form of the equations would be used in the established method. However, according to the ability of the method to reconsider the minor omitted parameters in modeling during the solution procedure, the axial load in the elements at each stage of the iteration can be computed and applied in the next stage. Therefore, the ability of the method to present an accurate approach to the solutions of non-linear equations will be demonstrated again in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nonlinear" title="nonlinear">nonlinear</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a>, <a href="https://publications.waset.org/abstracts/search?q=buckling" title=" buckling"> buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20%20newmark%20method" title=" modified newmark method"> modified newmark method</a> </p> <a href="https://publications.waset.org/abstracts/42635/second-order-analysis-of-frames-using-modified-newmark-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42635.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">425</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">42</span> Investigation of Flexural – Torsion Instability of Struts Using Modified Newmark Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Amin%20Vakili">Seyed Amin Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahar%20Sadat%20Vakili"> Sahar Sadat Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Ehsan%20Vakili"> Seyed Ehsan Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Nader%20Abdoli%20Yazdi"> Nader Abdoli Yazdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Differential equations are of fundamental importance in engineering and applied mathematics, since many physical laws and relations appear mathematically in the form of such equations. The equilibrium state of structures consisting of one-dimensional elements can be described by an ordinary differential equation. The response of these kinds of structures under the loading, namely relationship between the displacement field and loading field, can be predicted by the solution of these differential equations and on satisfying the given boundary conditions. When the effect of change of geometry under loading is taken into account in modeling of equilibrium state, then these differential equations are partially integrable in quartered. They also exhibit instability characteristics when the structures are loaded compressively. The purpose of this paper is to represent the ability of the Modified Newmark Method in analyzing flexural-torsional instability of struts for both bifurcation and non-bifurcation structural systems. The results are shown to be very accurate with only a small number of iterations. The method is easily programmed, and has the advantages of simplicity and speeds of convergence and easily is extended to treat material and geometric nonlinearity including no prismatic members and linear and nonlinear spring restraints that would be encountered in frames. In this paper, these abilities of the method will be extended to the system of linear differential equations that govern strut flexural torsional stability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=instability" title="instability">instability</a>, <a href="https://publications.waset.org/abstracts/search?q=torsion" title=" torsion"> torsion</a>, <a href="https://publications.waset.org/abstracts/search?q=flexural" title=" flexural"> flexural</a>, <a href="https://publications.waset.org/abstracts/search?q=buckling" title=" buckling"> buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20newmark%20method%20stability" title=" modified newmark method stability"> modified newmark method stability</a> </p> <a href="https://publications.waset.org/abstracts/42636/investigation-of-flexural-torsion-instability-of-struts-using-modified-newmark-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42636.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">358</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">41</span> Women Retelling the Iranian Revolution: A Comparative Study of Novelists Maryam Madjidi and Negar Djavadi </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alessandro%20Giardino">Alessandro Giardino</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Iranian Revolution has been the object of numberless historical and semi-fictional accounts, often providing a monolithic perspective on the events, due to the westerner positioning of those recounting them. Against this tradition, two contemporary French-Iranian novels "Disoriental" (2016) by Negar Djavadi and "Marx and The Doll" (2017) by Maryam Madjidi have offered readers a female-oriented and interestingly layered representation of the Iranian Revolution, hence addressing the responsibilities and misconceptions of Western countries. Furthermore, these two women writers have shed light on the disenchantment of the Iranian intellectual class vis-à-vis the foundation of the Islamic Republic, by particularly focusing on the deterioration of women’s rights, as well as the repression of political, ethnical, religious and sexual minorities. By a psycholinguistic and semasiological analysis of the two novels by Djavadi and Madjidi, this essay will focus on alternative accounts of the revolution in order to reflect upon the role of intersectional literature to the understanding of history. More specifically, as both women, refugees, and bi-cultural writers, Djavadi and Madjidi unearthed moments and figures of the revolution which had disappeared from the prevalent narrative. In doing so, however, these two writers resorted to entirely opposite styles of writing that, it will be argued, stem from different types of female resistance. In defining these two approaches as a "narrative resistance" and a "photographic resistance," the essay will elucidate the dependence of these writers’ language on generational and psychological factors, but it will also stir a reflection on their different communicative strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iranian%20revolution" title="Iranian revolution">Iranian revolution</a>, <a href="https://publications.waset.org/abstracts/search?q=French-Iranian" title=" French-Iranian"> French-Iranian</a>, <a href="https://publications.waset.org/abstracts/search?q=intersectionality" title=" intersectionality"> intersectionality</a>, <a href="https://publications.waset.org/abstracts/search?q=literature" title=" literature"> literature</a>, <a href="https://publications.waset.org/abstracts/search?q=women%20writers" title=" women writers"> women writers</a> </p> <a href="https://publications.waset.org/abstracts/110463/women-retelling-the-iranian-revolution-a-comparative-study-of-novelists-maryam-madjidi-and-negar-djavadi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110463.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">157</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">40</span> Communicative Competence versus Language Proficiency</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pouya%20Vakili">Pouya Vakili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of present paper is to have a rough comparison between language proficiency and communicative competence, moreover, how different scholars in the field of second language acquisition/assessment have defined competence in different paradigms.

Other researchers have adopted a broader perspective that is examining how learners acquire communicative competence (knowledge of both the L2 grammar and of how this system is put to use in actual communication). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=communicative%20competence" title="communicative competence">communicative competence</a>, <a href="https://publications.waset.org/abstracts/search?q=competence" title=" competence"> competence</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20proficiency" title=" language proficiency"> language proficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=linguistic%20competence" title=" linguistic competence"> linguistic competence</a> </p> <a href="https://publications.waset.org/abstracts/33462/communicative-competence-versus-language-proficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33462.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">487</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">39</span> Subtidal Crabs of Oman Sea: New Collections and Biogeographic Considerations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Negar%20Ghotbeddin">Negar Ghotbeddin</a>, <a href="https://publications.waset.org/abstracts/search?q=Seied%20Mohammad%20Reza%20Fatemi"> Seied Mohammad Reza Fatemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Tooraj%20Valinassab"> Tooraj Valinassab</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The samplings were carried out at 8 stations (Govatr, Pasabandar, Beriss, Ramin, Chabahar, Pozm, Gordim, and Meidani) in subtidal zones of Oman Sea during the year 2009-2010.

There are not only exceptionally many paths and educational means for arriving at a given educational goal, but there are also many types of educational materials which can be used to achieve that goal’. For language educators who are trying to incorporate technology into their curricula, the choices seem endless.

Therefore, NDN-IoT has emerged as a combined architecture which exploits the benefits of NDN for interconnecting of the heterogeneous objects in IoT. In NDN-IoT, caching schemes are a key role to improve the network performance. In this paper, we consider the effectiveness of cache replacement schemes in NDN-IoT scenarios. We investigate the impact of replacement schemes on average delay, average hop count, and average interest retransmission when replacement schemes are Least Frequently Used (LFU), Least Recently Used (LRU), First-In-First-Out (FIFO) and Random. The simulation results demonstrate that LFU and LRU present a stable performance when the cache size changes. Moreover, the network performance improves when the number of consumers increases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NDN-IoT" title="NDN-IoT">NDN-IoT</a>, <a href="https://publications.waset.org/abstracts/search?q=cache%20replacement" title=" cache replacement"> cache replacement</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=ndnSIM" title=" ndnSIM"> ndnSIM</a> </p> <a href="https://publications.waset.org/abstracts/84255/on-performance-of-cache-replacement-schemes-in-ndn-iot" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84255.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">365</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">36</span> The Application of to Optimize Pellet Quality in Broiler Feeds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reza%20Vakili">Reza Vakili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this experiment was to optimize the effect of moisture, the production rate, grain particle size and steam conditioning temperature on pellet quality in broiler feed using Taguchi method and a 43 fractional factorial arrangement was conducted.

We introduce methods in LC sampling that reduce the sampling rate close to the Nyquist frequency even for large bit-depth. The results indicate that larger variation in the sampling intervals leads to an alias-free sampling scheme; this is achieved by either reducing the bit-depth or adding jitter to the system for high bit-depths. In conjunction with windowing, the signal is reconstructed from the LC samples using an efficient Toeplitz reconstruction algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alias-free" title="alias-free">alias-free</a>, <a href="https://publications.waset.org/abstracts/search?q=level%20crossing%20sampling" title=" level crossing sampling"> level crossing sampling</a>, <a href="https://publications.waset.org/abstracts/search?q=spectrum" title=" spectrum"> spectrum</a>, <a href="https://publications.waset.org/abstracts/search?q=trigonometric%20polynomial" title=" trigonometric polynomial"> trigonometric polynomial</a> </p> <a href="https://publications.waset.org/abstracts/136144/efficient-alias-free-level-crossing-sampling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136144.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">209</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">34</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.

The typical requisites and relevant equipment for the development of a wobbled laser processing unit are addressed, including a suitable laser source, light delivery system, optics, proper beam deflection system and the design geometry. In addition, experiments have been carried out on titanium plate to compare the results of wobbled laser welding with conventional pulsed laser welding. As compared to the pulsed laser welding, the wobbled laser welding offers a much greater fusion area (i.e. additional molten material) while minimizing the HAZ and provides a better confinement of the material microstructural changes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wobbled%20laser%20beam%20welding" title="wobbled laser beam welding">wobbled laser beam welding</a>, <a href="https://publications.waset.org/abstracts/search?q=wobbling%20function" title=" wobbling function"> wobbling function</a>, <a href="https://publications.waset.org/abstracts/search?q=beam%20oscillation" title=" beam oscillation"> beam oscillation</a>, <a href="https://publications.waset.org/abstracts/search?q=micro%20welding" title=" micro welding"> micro welding</a> </p> <a href="https://publications.waset.org/abstracts/56603/wobbled-laser-beam-welding-for-macro-to-micro-fabrication-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56603.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">328</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">29</span> Preparation and Characterization of Electrospun CdTe Quantum Dots / Nylon-6 Nanofiber Mat</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Negar%20Mesgara">Negar Mesgara</a>, <a href="https://publications.waset.org/abstracts/search?q=Laleh%20Maleknia"> Laleh Maleknia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, electrospun CdTe quantum dot / nylon-6 nanofiber mats were successfully prepared. The nanofiber mats were characterized by FE-SEM, XRD and EDX analyses. The results revealed that fibers in different distinct sizes (nano and subnano scale) were obtained with the electrospinning parameters. The phenomenon of ‘on ‘ and ‘off ‘ luminescence intermittency (blinking) of CdTe QDs in nylon-6 was investigated by single-molecule optical microscopy, and we identified that the intermittencies of single QDs were correlated with the interaction of water molecules absorbed on the QD surface. The ‘off’ times, the interval between adjacent ‘on’ states, remained essentially unaffected with an increase in excitation intensity. In the case of ‘on’ time distribution, power law behavior with an exponential cutoff tail is observed at longer time scales. These observations indicate that the luminescence blinking statistics of water-soluble single CdTe QDs is significantly dependent on the aqueous environment, which is interpreted in terms of passivation of the surface trap states of QDs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title="electrospinning">electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=CdTe%20quantum%20dots" title=" CdTe quantum dots"> CdTe quantum dots</a>, <a href="https://publications.waset.org/abstracts/search?q=Nylon-6" title=" Nylon-6"> Nylon-6</a>, <a href="https://publications.waset.org/abstracts/search?q=Nanocomposite" title=" Nanocomposite"> Nanocomposite</a> </p> <a href="https://publications.waset.org/abstracts/34595/preparation-and-characterization-of-electrospun-cdte-quantum-dots-nylon-6-nanofiber-mat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34595.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">434</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Investigating the Role of Positive Adolescent Development on Hope for the Future in Adolescents Aged 14 to 18 with Anxiety in the City of Ahvaz in the Country of Iran in 2023</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Negar%20Mirzaie">Negar Mirzaie</a>, <a href="https://publications.waset.org/abstracts/search?q=Hedayet%20Allah%20Sharifi"> Hedayet Allah Sharifi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study was conducted with the aim of investigating the role of positive adolescent development on hope for the future in adolescents aged 14 to 18 with anxiety in the city of Ahvaz in the country of Iran in 2023.

Experimental samples were including two diets with different concentrate: forage ratio (80:20 and 60:40) with eight treatments (1:Control diet 60:40 without BIP,2: 60:40 diet with 25% BIP, 3:60:40 diet with 50% BIP, 4: 60:40 diet with 75% BIP,5: Control diet 80:20 without BIP,6: 80:20 diet with 25% BIP,7: 80:20 diet with 50% BIP and 8: 80:20 diet with 75% BIP) and eight repeats. The trial was analyzed considering a completely randomized design by the GLM procedure of SAS 9.1. Means among treatment were compared by Tukey test. The results of this study showed that in food with 80:20 (concentrate: forage), adding BIP 25% did not statistically change NH3-N (p > 0.05) compared to the control treatment but there was a significant difference (p < 0.05) between the effect of BIP 50% on NH3-N compared to the BIP 25% and the control. In diet with 60:40 (concentrate: forage), there was no significant difference between the effect of BIP 25% on NH3-N and the control, nor was there a significant difference between the effect of BIP 50% and 75%, while a significant difference (p < 0.05) between BIP 50% and 75% and the rest was observed. The propolis extract makes nitrogen ammonia decrease. This may help the nitrogen retain longer in ruminants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brown%20Iranian%20propolis" title="brown Iranian propolis">brown Iranian propolis</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20vitro" title=" in vitro"> in vitro</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrogen%20ammonia" title=" nitrogen ammonia"> nitrogen ammonia</a>, <a href="https://publications.waset.org/abstracts/search?q=ruminant" title=" ruminant"> ruminant</a> </p> <a href="https://publications.waset.org/abstracts/50895/the-effects-of-phenolic-compounds-in-brown-iranian-propolis-extracts-on-ruminal-nitrogen-ammonia-concentration-in-in-vitro" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50895.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">487</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">26</span> Investigating the Effect of Adding the Window Layer and the Back Surface Field Layer of InₓGa₍₁₋ₓ₎P Material to GaAs Single Junction Solar Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Taghinia">Ahmad Taghinia</a>, <a href="https://publications.waset.org/abstracts/search?q=Negar%20Gholamishaker"> Negar Gholamishaker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> GaAs (gallium arsenide) solar cells have gained significant attention for their use in space applications.

Due to Shandiz’s natural beauty, suitable climate, and its close proximity to Mashhad which is the largest city in the eastern half of the country, many people own second houses in this area. In addition to this, Shandiz hosts millions of visitors annually. Its economic role, which is parallel and complementary to Mashhad, has caused population growth, the increase of activities, and physical expansion, all of which exceed the city’s capacity. The aim of this descriptive and analytical study was to evaluate the impact of city expansion on the environment and aid in preventing further harm to the natural environment of this perimeter. Data were collected from population and housing statistics during a different period of time-based on GIS. Results show that the existence of an integrated environmental management system in order to coordinate development projects and the expansion of tourism programs that meet environmental conditions are necessary and achieving sustainable development with quality of life in this area without considering environmental limitations and capabilities cannot be sustained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=population%20growth" title="population growth">population growth</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism" title=" tourism"> tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20development" title=" physical development"> physical development</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20impact" title=" environmental impact"> environmental impact</a>, <a href="https://publications.waset.org/abstracts/search?q=Shandiz%20City" title=" Shandiz City "> Shandiz City </a> </p> <a href="https://publications.waset.org/abstracts/20016/a-review-of-the-environmental-impact-of-physical-expansion-of-shandiz-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20016.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">350</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">24</span> Effect of Peppermint Essential Oil versus a Mixture of Formic and Propionic Acids on Corn Silage Volatile Fatty Acid Score</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Danesh%20Mesgaran">Mohsen Danesh Mesgaran</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Hodjatpanah%20Montazeri"> Ali Hodjatpanah Montazeri</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Vakili"> Alireza Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Mansoor%20Tahmasbei"> Mansoor Tahmasbei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To compare peppermint essential oil versus a mixture of formic and propionic acids a study was conducted to their effects on volatile fatty acid proportion and VFA score of corn silage. Chopped whole crop corn (control) was treated with peppermint essential oil (240 mg kg-1 DM) or a mixture of formic and propionic acids (2:1) at 0.4% of fresh forage weight, and ensiled for 30 days. Then, silage extract was provided and the concentration of each VFA was determined using gas chromatography. The VFA score was calculated according to the patented formula proposed by Dairy One Scientific Committee. The score is calculated based on the positive impact of lactic and acetic acids versus the negative effect of butyric acid to achieve a single value for evaluating silage quality. The essential oil declined pH and increased the concentration of lactic and acetic acids in the silage extract. All corn silages evaluated in this study had a VFA score between 6 through 8. However, silage with peppermint essential oils had lower volatile fatty acids score than those of the other treatments. Both of applied additives caused a significant improvement in silage aerobic stability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=peppermint" title="peppermint">peppermint</a>, <a href="https://publications.waset.org/abstracts/search?q=essential%20oil" title=" essential oil"> essential oil</a>, <a href="https://publications.waset.org/abstracts/search?q=corn%20silage" title=" corn silage"> corn silage</a>, <a href="https://publications.waset.org/abstracts/search?q=VFA%20%28volatile%20fatty%20acids%29" title=" VFA (volatile fatty acids)"> VFA (volatile fatty acids)</a> </p> <a href="https://publications.waset.org/abstracts/63626/effect-of-peppermint-essential-oil-versus-a-mixture-of-formic-and-propionic-acids-on-corn-silage-volatile-fatty-acid-score" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63626.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">407</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">23</span> Radial Distribution Network Reliability Improvement by Using Imperialist Competitive Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azim%20Khodadadi">Azim Khodadadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahar%20Sadaat%20Vakili"> Sahar Sadaat Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebrahim%20Babaei"> Ebrahim Babaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents a numerical method to optimize the failure rate and repair time of a typical radial distribution system. Failure rate and repair time are effective parameters in customer and energy based indices of reliability. Decrease of these parameters improves reliability indices. Thus, system stability will be boost. The penalty functions indirectly reflect the cost of investment which spent to improve these indices. Constraints on customer and energy based indices, i.e. SAIFI, SAIDI, CAIDI and AENS have been considered by using a new method which reduces optimization algorithm controlling parameters. Imperialist Competitive Algorithm (ICA) used as main optimization technique and particle swarm optimization (PSO), simulated annealing (SA) and differential evolution (DE) has been applied for further investigation. These algorithms have been implemented on a test system by MATLAB. Obtained results have been compared with each other. The optimized values of repair time and failure rate are much lower than current values which this achievement reduced investment cost and also ICA gives better answer than the other used algorithms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=imperialist%20competitive%20algorithm" title="imperialist competitive algorithm">imperialist competitive algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=failure%20rate" title=" failure rate"> failure rate</a>, <a href="https://publications.waset.org/abstracts/search?q=repair%20time" title=" repair time"> repair time</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20distribution%20network" title=" radial distribution network"> radial distribution network</a> </p> <a href="https://publications.waset.org/abstracts/27260/radial-distribution-network-reliability-improvement-by-using-imperialist-competitive-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27260.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">668</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">22</span> A Review of Masonry Buildings Restrengthening Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Negar%20Sartipzadeh">Negar Sartipzadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The historic buildings are generally the ones which have been built by materials like brick, mud, stone, and wood. Some phenomena such as severe earthquakes can be tremendously detrimental to the structures, imposing serious effects and losses on such structures. Hence, it matters a lot to ascertain safety and reliability of the structures under such circumstances. It has been asserted that the major reason for the collapse of Unreinforced Masonry (URM) in various earthquakes is the incapability of resisting the forces and vice versa because such URMs are meant for the gravity load and they fail to withstand the shear forces inside the plate and the bending forces outside the plate. For this reason, restrengthening such structures is a key factor in lowering the seismic loss in developing countries. Seismic reinforcement of the historic buildings with regard to their cultural value on one hand, and exhaustion and damage of many of the structural elements on the other hand, have brought in restricting factors which necessitate the seismic reinforcement methods meant for such buildings to be maximally safe, non-destructive, effective, and non-obvious. Henceforth, it is pinpointed that making use of diverse technologies such as active controlling, Energy dampers, and seismic separators besides the current popular methods would be justifiable for such buildings, notwithstanding their high imposed costs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=masonry%20buildings" title="masonry buildings">masonry buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20reinforcement" title=" seismic reinforcement"> seismic reinforcement</a>, <a href="https://publications.waset.org/abstracts/search?q=Unreinforced%20Masonry%20%28URM%29" title=" Unreinforced Masonry (URM)"> Unreinforced Masonry (URM)</a>, <a href="https://publications.waset.org/abstracts/search?q=earthquake" title=" earthquake"> earthquake</a> </p> <a href="https://publications.waset.org/abstracts/11241/a-review-of-masonry-buildings-restrengthening-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11241.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">280</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">21</span> Experimental Investigation of Partially Premixed Laminar Methane/Air Co-Flow Flames Using Mach-Zehnder Interferometry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Misagh%20Irandoost%20Shahrestani">Misagh Irandoost Shahrestani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Ashjaee"> Mehdi Ashjaee</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahrokh%20Zandieh%20Vakili"> Shahrokh Zandieh Vakili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, partially premixed laminar methane/air co-flow flame is studied experimentally. Methane-air flame was established on an axisymmetric coannular burner. The fuel-air jet flows from the central tube while the secondary air flows from the region between the inner and the outer tube. The aim is to investigate the flame features and to develop a nonintrusive method for temperature measurement of methane/air partially premixed flame using Mach-Zehnder interferometry method. Different equivalence ratios and Reynolds numbers are considered. Flame generic visible appearance was also investigated and its various structures were studied. Three distinguished flame regimes were seen based on its appearance. A double flame structure can be seen for the equivalence ratio in the range of 1<Φ<2.1. By adding air to the mixture up to Φ=4 the flame has the characteristics of both premixed and non-premixed flames. Finally for 4<Φ<∞ the flame mainly becomes non-premixed like and the luminous sooting region on its tip is the obvious feature of this type of flames. The Mach-Zehnder method is used to obtain temperature field of a transparent fluid by means of index of refraction. Temperature obtained from optical techniques was compared with that of obtained from thermocouples in order to validate the results. Good agreement was observed for these two methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flame%20structure" title="flame structure">flame structure</a>, <a href="https://publications.waset.org/abstracts/search?q=Mach-Zehnder%20interferometry" title=" Mach-Zehnder interferometry"> Mach-Zehnder interferometry</a>, <a href="https://publications.waset.org/abstracts/search?q=partially%20premixed%20flame" title=" partially premixed flame"> partially premixed flame</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20field" title=" temperature field "> temperature field </a> </p> <a href="https://publications.waset.org/abstracts/17291/experimental-investigation-of-partially-premixed-laminar-methaneair-co-flow-flames-using-mach-zehnder-interferometry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17291.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">481</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">20</span> The Relationship Between The Two-spatial World And The Decrease In The Area Of Commercial Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syedhossein%20%20Vakili">Syedhossein Vakili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> According to the opinion of some experts, the world's two-spatialization means the establishment of a new virtual space and placing this new space next to the physical space. This dualization of space has left various effects, one of which is reducing the need for buildings and making the area of business premises economical through the use of virtual space instead of a part of physical space. In such a way that before the virtual space was known, a commercial or educational institution had to block a large part of its capital to acquire physical spaces and buildings in order to provide physical space and places needed for daily activities, but today, Thanks to the addition of the virtual space to the physical space, it has been possible to carry out its activities more widely in a limited environment with a minimum of physical space and drastically reduce costs. In order to understand the impact of virtual space on the reduction of physical space, the researcher used the official reports of the countries regarding the average area mentioned in the permits for the construction of commercial and educational units in the period from 2014 to 2023 and compared the average capital required for the absolute physical period with The period of two-spatialization of the world in the mentioned ten-year period, while using the analytical and comparative method, has proven that virtual space has greatly reduced the amount of investment of business owners to provide the required place for their activities by reducing the need for physical space. And economically, it has made commercial activities more profitable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=two%20spatialization" title="two spatialization">two spatialization</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20area" title=" building area"> building area</a>, <a href="https://publications.waset.org/abstracts/search?q=cyberspace" title=" cyberspace"> cyberspace</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20space" title=" physical space"> physical space</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20place" title=" virtual place"> virtual place</a> </p> <a href="https://publications.waset.org/abstracts/185870/the-relationship-between-the-two-spatial-world-and-the-decrease-in-the-area-of-commercial-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185870.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">59</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">19</span> Designing Sustainable Building Based on Iranian's Windmills </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Negar%20Sartipzadeh">Negar Sartipzadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Energy-conscious design, which coordinates with the Earth ecological systems during its life cycle, has the least negative impact on the environment with the least waste of resources. Due to the increasing in world population as well as the consumption of fossil fuels that cause the production of greenhouse gasses and environmental pollution, mankind is looking for renewable and also sustainable energies. The Iranian native construction is a clear evidence of energy-aware designing. Our predecessors were forced to rely on the natural resources and sustainable energies as well as environmental issues which have been being considered in the recent world. One of these endless energies is wind energy. Iranian traditional architecture foundations is a appropriate model in solving the environmental crisis and the contemporary energy. What will come in this paper is an effort to recognition and introduction of the unique characteristics of the Iranian architecture in the application of aerodynamic and hydraulic energies derived from the wind, which are the most common and major type of using sustainable energies in the traditional architecture of Iran. Therefore, the recent research attempts to offer a hybrid system suggestions for application in new constructions designing in a region such as Nashtifan, which has potential through reviewing windmills and how they deal with sustainable energy sources, as a model of Iranian native construction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title="renewable energy">renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20building" title=" sustainable building"> sustainable building</a>, <a href="https://publications.waset.org/abstracts/search?q=windmill" title=" windmill"> windmill</a>, <a href="https://publications.waset.org/abstracts/search?q=Iranian%20architecture" title=" Iranian architecture "> Iranian architecture </a> </p> <a href="https://publications.waset.org/abstracts/11242/designing-sustainable-building-based-on-iranians-windmills" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11242.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">422</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">18</span> Efficient High Fidelity Signal Reconstruction Based on Level Crossing Sampling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Negar%20Riazifar">Negar Riazifar</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigel%20G.%20Stocks"> Nigel G. Stocks</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes strategies in level crossing (LC) sampling and reconstruction that provide high fidelity signal reconstruction for speech signals; these strategies circumvent the problem of exponentially increasing number of samples as the bit-depth is increased and hence are highly efficient. Specifically, the results indicate that the distribution of the intervals between samples is one of the key factors in the quality of signal reconstruction; including samples with short intervals do not improve the accuracy of the signal reconstruction, whilst samples with large intervals lead to numerical instability. The proposed sampling method, termed reduced conventional level crossing (RCLC) sampling, exploits redundancy between samples to improve the efficiency of the sampling without compromising performance. A reconstruction technique is also proposed that enhances the numerical stability through linear interpolation of samples separated by large intervals. Interpolation is demonstrated to improve the accuracy of the signal reconstruction in addition to the numerical stability. We further demonstrate that the RCLC and interpolation methods can give useful levels of signal recovery even if the average sampling rate is less than the Nyquist rate. <p
