This squib argues that binding theory alone is not sufficient to explain the linguistic facts and proposes an analysis adopting the Agree operation. The current analysis correctly predicts all the possible and impossible structures, with an additional hypothesis that Mongolian possessive suffixes serve as an antecedent for PROs in adjunct. The findings thus provide insights into how Agree operates in Mongolian language. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=syntax" title="syntax">syntax</a>, <a href="https://publications.waset.org/abstracts/search?q=Mongolian" title=" Mongolian"> Mongolian</a>, <a href="https://publications.waset.org/abstracts/search?q=agreement" title=" agreement"> agreement</a>, <a href="https://publications.waset.org/abstracts/search?q=possessive%20particles" title=" possessive particles"> possessive particles</a> </p> <a href="https://publications.waset.org/abstracts/157755/an-analysis-of-mongolian-possessive-markers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157755.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">101</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">1735</span> Determiner Phrase in Persian</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reza%20Morad%20Sahraei">Reza Morad Sahraei</a>, <a href="https://publications.waset.org/abstracts/search?q=Roghayeh%20Kazeminahad"> Roghayeh Kazeminahad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Surveying the structure of NP in Persian, this article tries to show that most of NP constituents are either independent of each other or they are dependent to Determiner Phrase (=DP).

The most important point of this article is the claim that NP is mostly one of the dependents of DP. Hence, the final section of the article deals with and analyzes the structure of DP in Persian. The DP analysis undertaken in this article has some advantages. It can explain the internal relevance of all DP constituents and provides them all a uniform analysis.

This locative constituent either surface as a true locative phrase or are realized as a possessor noun phrase. However, while much research focuses on the supposed underlying syntactic relation of locative and possessive existential constructions, not much is known about possible semantic factors that could govern the choice between these constructions. The main question that we address in this talk concerns the choice between the two related constructions in Modern Standard Arabic (MAS). Although both are used to express the existence of something somewhere, we can distinguish three contexts: First, for some types of entities, only the EL construction is possible (e.g. (1a) ṯammata raǧulun fī l-ḥadīqati vs. (1b) *(kāna) ladā l-ḥadīqati raǧulun). Second, for other types of entities, only the possessive construction is possible (e.g. (2a) ladā ṭ-ṭawilati aklun dāʾiriyyun vs. (2b) *ṯammata šaklun dāʾiriyyun ladā/fī ṭ-ṭawilati). Finally, for still other entities, both constructions can be found (e.g. (3a) ṯammata ḥubbun lā yūṣafu ladā ǧārī li-zawǧati-hi and (3b) ladā ǧārī ḥubbun lā yūṣafu li-zawǧati-hi). The data covering a range of ontologically different entities (concrete objects, events, body parts, dimensions, essential qualities, feelings, etc.) shows that the choice between the existential locative and the possessive constructions is closely linked to the conceptual autonomy of the existential theme with respect to its location or to the whole that it is a part of. The construction with ṯammata is the only possible one to express the existence of a fully autonomous (i.e. nondependent) entity (concrete objects (e.g.1) and abstract objects such as events, especially the ones that Grimshaw called ‘simple events’). The possessive construction with (kāna) ladā is the only one used to express the existence of fully non-autonomous (i.e. fully dependent on a whole) entities (body parts, dimensions (e.g. 2), essential qualities). The two constructions alternate when the existential theme is conceptually dependent but separable of the whole, either because it has an autonomous (independent) existence of the given whole (spare parts of an object), or because it receives a relative autonomy in the speech through a modifier (accidental qualities, feelings (e.g. 3a, 3b), psychological states, among some other kinds of themes). In this case, the modifier expresses an approximate boundary on a scale, and provides relative autonomy to the entity. Finally, we will show that kinship terms (e.g. son), which at first sight may seem to constitute counterexamples to our hypothesis, are nonetheless supported by it. The ontological (non-)autonomy of located or possessed entities is also reflected by morpho-syntactic properties, among them the use and the choice of determiners, pluralisation and the behavior of entities in the context of associative anaphora. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=existence" title="existence">existence</a>, <a href="https://publications.waset.org/abstracts/search?q=possession" title=" possession"> possession</a>, <a href="https://publications.waset.org/abstracts/search?q=autonomous%20entities" title=" autonomous entities"> autonomous entities</a>, <a href="https://publications.waset.org/abstracts/search?q=non-autonomous%20entities" title=" non-autonomous entities"> non-autonomous entities</a> </p> <a href="https://publications.waset.org/abstracts/44185/existential-and-possessive-constructions-in-modern-standard-arabic-two-strategies-reflecting-the-ontological-non-autonomy-of-located-or-possessed-entities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44185.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">1733</span> Microscopic Visualization of the Ice Slurry Ice Particles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20Jos%C3%A9%20Mil%C3%B3n%20Guzm%C3%A1n">Juan José Milón Guzmán</a>, <a href="https://publications.waset.org/abstracts/search?q=Herbert%20Jes%C3%BAs%20Del%20Carpio%20Beltr%C3%A1n"> Herbert Jesús Del Carpio Beltrán</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergio%20Leal%20Braga"> Sergio Leal Braga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Visualizations of ice particles of ice slurry are performed.

Consequently, combined with special relativity, it leads to the conclusion that material particles of zero rest mass cannot exist in nature. Thus, causality, a principle without which nature would be incomprehensible, combined with special relativity, forbids the existence of material particles of zero rest mass. For instance, the neutrinos, as is now known, are material particles of non-zero rest mass. The situation changes when we consider the gauge particles. In fact, when the principle of causality was proposed, the concept of gauge particles had not yet been introduced. Now we know that photon, a gauge particle with zero rest mass does exist in nature. Therefore, principle of causality, as generally stated, is valid only for material particles. For gauge particles, in order to make the statement of causality consistent with experiment, it has to be modified: The cause should either precede or be simultaneous with the effect. Combined with special relativity, it allows gauge particles of zero rest mass. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=causality" title="causality">causality</a>, <a href="https://publications.waset.org/abstracts/search?q=gauge%20particles" title=" gauge particles"> gauge particles</a>, <a href="https://publications.waset.org/abstracts/search?q=material%20particles" title=" material particles"> material particles</a>, <a href="https://publications.waset.org/abstracts/search?q=special%20relativity" title=" special relativity"> special relativity</a> </p> <a href="https://publications.waset.org/abstracts/31503/causality-special-relativity-and-non-existence-of-material-particles-of-zero-rest-mass" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31503.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">501</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">1731</span> Particle Size Distribution Estimation of a Mixture of Regular and Irregular Sized Particles Using Acoustic Emissions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ejay%20Nsugbe">Ejay Nsugbe</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Starr"> Andrew Starr</a>, <a href="https://publications.waset.org/abstracts/search?q=Ian%20Jennions"> Ian Jennions</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristobal%20Ruiz-Carcel"> Cristobal Ruiz-Carcel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This works investigates the possibility of using Acoustic Emissions (AE) to estimate the Particle Size Distribution (PSD) of a mixture of particles that comprise of particles of different densities and geometry.

Scanning electron microscopy images of the particles were analyzed using computer software. The evolution of tin film dewetting into particles initiated from the hole nucleation in grain boundaries. Increasing ICP power during plasma treatment produced larger number of particles per area and smaller particle size and particle-size distribution.

An overview of these methods, their implementation, their advantages and their limits is also present here. It has been accepted that wear particles contain major information about wear and friction of materials. Morphological analysis of wear particles from a lubricant is a very effective way for machine condition monitoring. Fractal dimension methods are used to characterize the morphology of the found particles. It is very useful in the analysis of complexity of irregular substance.

The mechanism of particles diffusions by melt turning and stirring that makes vortexes help the particles entrance in the matrix of base alloy also has been studied. The samples of metallic composites (MMCs) with dispersed particles percentages (4% - 6% - 8% - 10% - 15% and 20%) are prepared. The effect of the particles dispersion on the mechanical properties of produced samples were carried out by tension & hardness tests. It is found that the ultimate tensile strength of the produced composites can be increased by increasing the percentages of alumina particles in the matrix of the base alloy.

The surface is covered with untreated, hydrophilic, and a combination of hydrophobic and hydrophilic copper particles separately, and the heat flux and wall superheat temperature was measured experimentally and compared with the bare polished copper surface.

It is due to the entrapment of particles in the wakes of upstream particles. In this paper, the effect of bi-dispersity of settling particles on particle clustering is investigated using particle-resolved direct numerical simulation. Immersed boundary method is used for particle fluid interactions and discrete element method is used for particle-particle interactions. The solid volume fraction used in the simulation is 1% and the Reynolds number based on Sauter mean diameter is 350. Both solid volume fraction and Reynolds number lie in the clustering regime of sedimentation. In simulations, the particle diameter ratio (i.e. diameter of larger particle to smaller particle (d₁/d₂)) is varied from 2:1, 3:1 and 4:1. For each case of particle diameter ratio, solid volume fraction for each particle size (φ₁/φ₂) is varied from 1:1, 1:2 and 2:1. For comparison, simulations are also performed for monodisperse particles. For studying particles clustering, radial distribution function and instantaneous location of particles in the computational domain are studied. It is observed that the degree of particle clustering decreases with the increase in the bi-dispersity of settling particles. The smallest degree of particle clustering or dispersion of particles is observed for particles with d₁/d₂ equal to 4:1 and φ₁/φ₂ equal to 1:2. Simulations showed that the reduction in particle clustering by increasing bi-dispersity is due to the difference in settling velocity of particles. Particles with larger size settle faster and knockout the smaller particles from clustered regions of particles in the computational domain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dispersion%20in%20bi-disperse%20settling%20particles" title="dispersion in bi-disperse settling particles">dispersion in bi-disperse settling particles</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20microstructures%20in%20bi-disperse%20suspensions" title=" particle microstructures in bi-disperse suspensions"> particle microstructures in bi-disperse suspensions</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20resolved%20direct%20numerical%20simulations" title=" particle resolved direct numerical simulations"> particle resolved direct numerical simulations</a>, <a href="https://publications.waset.org/abstracts/search?q=settling%20of%20bi-disperse%20particles" title=" settling of bi-disperse particles"> settling of bi-disperse particles</a> </p> <a href="https://publications.waset.org/abstracts/86250/effect-of-bi-dispersity-on-particle-clustering-in-sedimentation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86250.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">207</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">1725</span> Residual Stress Around Embedded Particles in Bulk YBa2Cu3Oy Samples</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anjela%20Koblischka-Veneva">Anjela Koblischka-Veneva</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20R.%20Koblischka"> Michael R. Koblischka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To increase the flux pinning performance of bulk YBa2Cu3O7-δ (YBCO or Y-123) superconductors, it is common to employ secondary phase particles, either Y2BaCuO5 (Y-211) particles created during the growth of the samples or additionally added (nano)particles of various types, embedded in the superconducting Y-123 matrix. As the crystallographic parameters of all the particles indicate a misfit to Y-123, there will be residual strain within the Y-123 matrix around such particles. With a dedicated analysis of electron backscatter diffraction (EBSD) data obtained on various bulk, Y-123 superconductor samples, the strain distribution around such embedded secondary phase particles can be revealed. The results obtained are presented in form of Kernel Average Misorientation (KAM) mappings. Around large Y-211 particles, the strain can be so large that YBCO subgrains are formed. Therefore, it is essential to properly control the particle size as well as their distribution within the bulk sample to obtain the best performance. The impact of the strain distribution on the flux pinning properties is discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bulk%20superconductors" title="Bulk superconductors">Bulk superconductors</a>, <a href="https://publications.waset.org/abstracts/search?q=EBSD" title=" EBSD"> EBSD</a>, <a href="https://publications.waset.org/abstracts/search?q=Strain" title=" Strain"> Strain</a>, <a href="https://publications.waset.org/abstracts/search?q=YBa2Cu3Oy" title=" YBa2Cu3Oy"> YBa2Cu3Oy</a> </p> <a href="https://publications.waset.org/abstracts/122638/residual-stress-around-embedded-particles-in-bulk-yba2cu3oy-samples" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122638.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">150</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1724</span> Percolation Transition in an Agglomeration of Spherical Particles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Johannes%20J.%20Schneider">Johannes J.

Two types of particles are considered, with one of them being able to create connections to neighboring particles of the same type, thus forming a network within the agglomeration at the bottom of a cylinder.

In this study, we utilized Polylactic acid particles as stimulants for macrophages and the collagen synthesis of co-cultured fibroblasts was evaluated. The results indicated that Polylactic acid particles were nontoxic to cells from 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide. No obvious inflammation effect was observed (under the PLLA concentration of 1 mg/mL) after 24-h co-culture of Raw264.7 and NIH3T3 cells (from TNF-α assay). The addition of PLLA particles to the Raw264.7 and NIH3T3 co-cultures increased the synthesis of collagen, the highest collagen synthesis from the fibroblast was the 0.2 mg/mL (approximately 60% increased as compared with without addition Polylactic acid particles). Moreover, a co-axial atomization delivery device was used to percutaneously introduce Polylactic acid particles into the dermis layer and stimulating macrophages to secrete growth factors promoting fibroblasts to produce collagen. The preliminary results demonstrated the synthesis of collagen was increased mildly after the introduction of Polylactic acid particles for 28-d post implantation. The Polylactic acid particles could be successfully introduced into the dermis layer from H&E staining examination, however, the optimum concentration of Polylactic acid particles and the time-period for collagen synthesis still need to be evaluated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collagen%20synthesis" title="collagen synthesis">collagen synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=macrophage" title=" macrophage"> macrophage</a>, <a href="https://publications.waset.org/abstracts/search?q=NIH3T3%20cells" title=" NIH3T3 cells"> NIH3T3 cells</a>, <a href="https://publications.waset.org/abstracts/search?q=polylactic%20acid%20particles" title=" polylactic acid particles"> polylactic acid particles</a> </p> <a href="https://publications.waset.org/abstracts/156614/evaluation-of-collagen-synthesis-in-macrophagesfibroblasts-co-culture-using-polylactic-acid-particles-as-stimulants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156614.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">113</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1722</span> Effect of Al Particles on Corrosion Resistance of Electrodeposited Ni-Al Composite Coatings </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Adabi">M.

Electrodeposited composite coatings produced by dispersion of particles into the metal matrix show better properties than pure metallic coatings. In recent years, many researches were carried out on Ni matrix coatings reinforced by ceramic particles such as Ni-SiC, Ni-Al2O3, Ni-WC, Ni-CeO2, Ni-ZrO2, Ni-TiO2 to improve their corrosion and wear resistance. However, little effort has been made on incorporation of metal particles into Ni matrix. Therefore, the aim of this work was to produce Ni–Al composite coating on 6061 aluminum alloy by pulse plating and to investigate the effects of electrodeposition parameters, e.g. concentration Al particles in the electrolyte and current density, on composition and corrosion resistance of the composite coatings. The morphology and corrosion behavior of the coated 6061 Al alloys were studied by means of scanning electron microscope (SEM) equipped with energy dispersive X-ray spectrometer (EDS) and potentiodynamic polarization method, respectively. The results indicated that the addition of Al particles up to 50 g L-1 increased the amount of co-deposited Al particles in nickel matrix. It is also observed that the incorporation of Al particles decreased with increasing current density. Meanwhile, the corrosion resistance of the coatings shows an increment by increasing the content of Al particles into nickel matrix. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ni-Al%20composite%20coating" title="Ni-Al composite coating">Ni-Al composite coating</a>, <a href="https://publications.waset.org/abstracts/search?q=current%20density" title=" current density"> current density</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion%20resistance" title=" corrosion resistance "> corrosion resistance </a> </p> <a href="https://publications.waset.org/abstracts/24363/effect-of-al-particles-on-corrosion-resistance-of-electrodeposited-ni-al-composite-coatings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24363.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">1721</span> Novel Design of Quantum Dot Arrays to Enhance Near-Fields Excitation Resonances</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nour%20Hassan%20Ismail">Nour Hassan Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelmonem%20Nassar"> Abdelmonem Nassar</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Baz"> Khaled Baz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Semiconductor crystals smaller than about 10 nm, known as quantum dots, have properties that differ from large samples, including a band gap that becomes larger for smaller particles.

Examined chemicals were polyvinyl alcohol (nonionic polymer), poly(diallyl dimethyl ammonium chloride) (cationic polymer), poly(sodium 4-styrene-sulfonate) (anionic polymer), (2-aminopropyl) trimethoxy silane (APMS) (silane coupling agent with amino group), and (3-mercaptopropyl) trimethoxy silane (MPS) (silane coupling agent with thiol group). For all the examined chemicals, volume resistivities of surface-modified ITO particles did not increase much when they were aged in air at 80 <sup>o</sup>C, compared to a volume resistivity of un-surface-modified ITO particles. Increases in volume resistivities of ITO particles surface-modified with the silane coupling agents were smaller than those with the polymers, since hydrolysis of the silane coupling agents and condensation of generated silanol and OH groups on ITO particles took place to provide efficient immobilization of them on particles. The APMS gave an increase in volume resistivity smaller than the MPS, since a larger solubility in water of APMS providing a larger amount of APMS immobilized on particles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=indium%20tin%20oxide" title="indium tin oxide">indium tin oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=particles" title=" particles"> particles</a>, <a href="https://publications.waset.org/abstracts/search?q=surface-modification" title=" surface-modification"> surface-modification</a>, <a href="https://publications.waset.org/abstracts/search?q=volume%20resistivity" title=" volume resistivity"> volume resistivity</a> </p> <a href="https://publications.waset.org/abstracts/49172/effect-of-surface-modification-of-indium-tin-oxide-particles-on-their-electrical-conductivity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49172.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">253</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1716</span> Asymmetric of the Segregation-Enhanced Brazil Nut Effect</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Panupat%20Chaiworn">Panupat Chaiworn</a>, <a href="https://publications.waset.org/abstracts/search?q=Soraya%20lama"> Soraya lama</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We study the motion of particles in cylinders which are subjected to a sinusoidal vertical vibration.

In this work, the separation behaviors of different sized particles inside a reported curved micro-channel have been studied by a combined approach of computational fluid dynamics for gas and discrete element model for particles (CFD-DEM). The micro-channel is operated by controlling the gas flow rates at all of its branches respectively used to load particles, introduce gas streams, collect particles of various sizes. The validity of the model has been examined by comparing by the calculated separation efficiency of different sized particles against the measurement. On this basis, the separation mechanisms of the inertial microfluidic separator are elucidated in terms of the interactions between particles, between particle and fluid, and between particle and wall. The model is then used to study the effect of feed solids concentration on the separation accuracy and efficiency. The results obtained from the present study demonstrate that the CFD-DEM approach can provide a convenient way to study the particle separation behaviors in micro-channels of various types. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD-DEM" title="CFD-DEM">CFD-DEM</a>, <a href="https://publications.waset.org/abstracts/search?q=inertial%20effect" title=" inertial effect"> inertial effect</a>, <a href="https://publications.waset.org/abstracts/search?q=microchannel" title=" microchannel"> microchannel</a>, <a href="https://publications.waset.org/abstracts/search?q=separation" title=" separation"> separation</a> </p> <a href="https://publications.waset.org/abstracts/57240/cfd-dem-modelling-and-analysis-of-the-continuous-separation-of-sized-particles-using-inertial-microfluidics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57240.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">292</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">1714</span> Critical Velocities for Particle Transport from Experiments and CFD Simulations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sajith%20Sajeev">Sajith Sajeev</a>, <a href="https://publications.waset.org/abstracts/search?q=Brenton%20McLaury"> Brenton McLaury</a>, <a href="https://publications.waset.org/abstracts/search?q=Siamack%20Shirazi"> Siamack Shirazi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the petroleum industry, solid particles are often present along with the produced fluids.

In most of these multiphase operations the particles properties, i.e. size, density, and shape, may change during the process because of attrition, coalescence or chemical reactions. Previous studies, either experimentally or numerically, mainly have focused on studies of liquid-solid fluidized beds containing spherical particles; however, the role of particle shape on the hydrodynamics of liquid fluidized beds is still not well-known. A three-dimensional Discrete Element Model (DEM) and Computational Fluid Dynamics (CFD) are coupled to study the influence of particles shape on particles and liquid flow patterns in liquid-solid fluidized beds. In the simulations, ellipsoid particles are used to study the shape factor since they can represent a wide range of particles shape from oblate and sphere to prolate shape particles. Different particle shapes from oblate (disk shape) to elongated particles (rod shape) are selected to investigate the effect of aspect ratio on different flow characteristics such as general particles and liquid flow pattern, pressure drop, and particles orientation. First, the model is verified based on experimental observations, then further detail analyses are made. It was found that spherical particles showed a uniform particle distribution in the bed, which resulted in uniform pressure drop along the bed height. However for particles with aspect ratios less than one (disk-shape), some particles were carried into the freeboard region, and the interface between the bed and freeboard was not easy to be determined. A few particle also intended to leave the bed. On the other hand, prolate particles showed different behaviour in the bed. They caused unstable interface and some flow channeling was observed for low liquid velocities. Because of the non-uniform particles flow pattern for particles with aspect ratios lower (oblate) and more (prolate) than one, the pressure drop distribution in the bed was not observed as uniform as what was found for spherical particles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD" title="CFD">CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=DEM" title=" DEM"> DEM</a>, <a href="https://publications.waset.org/abstracts/search?q=ellipsoid" title=" ellipsoid"> ellipsoid</a>, <a href="https://publications.waset.org/abstracts/search?q=fluidization" title=" fluidization"> fluidization</a>, <a href="https://publications.waset.org/abstracts/search?q=multiphase%20flow" title=" multiphase flow"> multiphase flow</a>, <a href="https://publications.waset.org/abstracts/search?q=non-spherical" title=" non-spherical"> non-spherical</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/58426/cfd-dem-modelling-of-liquid-fluidizations-of-ellipsoidal-particles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58426.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">310</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">1712</span> Comparison of Particle Size for ɑ(Alpha) Fe2O3 and ɤ(Gamma)Fe2O3 on Heat Transfer Performance in an Copper Oscillating Heat Pipe</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Reza%20Goshayeshi">Hamid Reza Goshayeshi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effect of ɑ(alpha) Fe2O3 and ɤ(gamma)Fe2O3 particles on the heat transfer performance of an oscillating heat pipe was investigated experimentally.

The resolution of this method is high, and it is able to discriminate between alpha particles at different incident energy. It can measure the exact number of alpha particles at specific energy without needing a calibration of alpha track diameter versus alpha energy. This method was tested by using Cf-252 alpha standard source at energies 5.11 Mev, 3.86 MeV and 2.7 MeV, which produced by the variation of detector -standard source distance. On front side, two detectors were covered with two Aluminum thin films and the third detector was kept uncovered. The thickness of Aluminum thin films was selected carefully (using SRIM 2013) such that one of the films will block the lower two alpha particles (3.86 MeV and 2.7 MeV) and the alpha particles at higher energy (5.11 Mev) can penetrate the film and reach the detector’s surface. The second thin film will block alpha particles at lower energy of 2.7 MeV and allow alpha particles at higher two energies (5.11 Mev and 3.86 MeV) to penetrate and produce tracks. For uncovered detector, alpha particles at three different energies can produce tracks on it. For quality assurance and accuracy, the detectors were mounted on thick enough copper substrates to block exposure from the backside. The tracks on the first detector are due to alpha particles at energy of 5.11 MeV. The difference between the tracks number on the first detector and the tracks number on the second detector is due to alpha particles at energy of 3.8 MeV. Finally, by subtracting the tracks number on the second detector from the tracks number on the third detector (uncovered), we can find the tracks number due to alpha particles at energy 2.7 MeV. After knowing the efficiency calibration factor, we can exactly calculate the activity of standard source. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminium%20thin%20film" title="aluminium thin film">aluminium thin film</a>, <a href="https://publications.waset.org/abstracts/search?q=alpha%20particles" title=" alpha particles"> alpha particles</a>, <a href="https://publications.waset.org/abstracts/search?q=copper%20substrate" title=" copper substrate"> copper substrate</a>, <a href="https://publications.waset.org/abstracts/search?q=CR-39%20detector" title=" CR-39 detector"> CR-39 detector</a> </p> <a href="https://publications.waset.org/abstracts/41596/development-of-alpha-spectroscopy-method-with-solid-state-nuclear-track-detector-using-aluminium-thin-films" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41596.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">1709</span> Application of Stabilized Polyaniline Microparticles for Better Protective Ability of Zinc Coatings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Boshkova">N.

In this work, the preparation of stable suspensions of colloidal PANI-SiO<sub>2 </sub>particles, suitable for obtaining of composite anticorrosive coating on steel, is described. Electrokinetic data as a function of pH are presented, showing that the zeta potentials of the PANI-SiO<sub>2</sub> particles are governed primarily by the charged groups at the silica oxide surface. Electrosteric stabilization of the PANI-SiO<sub>2</sub> particles’ suspension against aggregation is realized at pH>5.5 (EB form of PANI) by adsorption of positively charged polyelectrolyte molecules onto negatively charged PANI-SiO<sub>2</sub> particles. The PANI-SiO<sub>2</sub> particles are incorporated by electrodeposition into the metal matrix of zinc in order to obtain composite (hybrid) coatings. The latter are aimed to ensure sacrificial protection of steel mainly in aggressive media leading to local corrosion damages. The surface morphology of the composite zinc coatings is investigated with SEM. The influence of PANI-SiO<sub>2</sub> particles on the cathodic and anodic processes occurring in the starting electrolyte for obtaining of the coatings is followed with cyclic voltammetry. The electrochemical and corrosion behavior is evaluated with potentiodynamic polarization curves and polarization resistance measurements. The beneficial effect of the stabilized PANI-SiO<sub>2</sub> particles for the increased protective ability of the composites is commented and discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrosion" title="corrosion">corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=polyaniline-silica%20particles" title=" polyaniline-silica particles"> polyaniline-silica particles</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc" title=" zinc"> zinc</a>, <a href="https://publications.waset.org/abstracts/search?q=protective%20ability" title=" protective ability"> protective ability</a> </p> <a href="https://publications.waset.org/abstracts/90974/application-of-stabilized-polyaniline-microparticles-for-better-protective-ability-of-zinc-coatings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90974.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">172</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">1708</span> A Unification and Relativistic Correction for Boltzmann’s Law</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lloyd%20G.%20Allred">Lloyd G.

Boltzmann’s law and the Maxwell-Boltzmann distribution describe the distribution of velocity of a particle in plasma as a function of mass and temperature. Particles with the same mass tend to have the same velocity. By expressing the same law in terms of energy alone, the author obtains a distribution independent of mass. In summary, for particles in plasma, the energies tend to equalize, independent of the masses of the individual particles. For high-energy plasma, the original law predicts velocities greater than the speed of light. If one uses Einstein’s formula for energy (<em>E=mc<sup>2</sup></em>), then a relativistic correction is not required. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cosmology" title="cosmology">cosmology</a>, <a href="https://publications.waset.org/abstracts/search?q=EMP" title=" EMP"> EMP</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20physics" title=" plasma physics"> plasma physics</a>, <a href="https://publications.waset.org/abstracts/search?q=relativity" title=" relativity"> relativity</a> </p> <a href="https://publications.waset.org/abstracts/84272/a-unification-and-relativistic-correction-for-boltzmanns-law" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84272.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">219</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">1707</span> Drum Scrubber Performance Assessment and Improvement to Achieve the Desired Product Quality</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prateek%20Singh">Prateek Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Arun%20Kumar%20Pandey"> Arun Kumar Pandey</a>, <a href="https://publications.waset.org/abstracts/search?q=C.%20Raghu%20Kumar"> C.

The purpose of the scrubber is to release the adhered fine clayey particles from the iron-bearing particles. Presently, the iron ore wash plants in the Eastern region of India consist of the scrubber, double deck screen followed by screw classifier as the main unit operations. Hence, scrubber performance efficiency has a huge impact on the downstream product quality. This paper illustrates the effect of scrubber feed % solids on scrubber performance and alumina distribution on downstream equipment. Further, it was established that scrubber performance efficiency could be defined as the ratio of the adhered particles (-0.15mm) released from scrubber feed during scrubbing operation with respect to the maximum possible release of -0.15mm (%) particles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=scrubber"
