take into account the fluid-structure coupling into an inverse method, the Force Analysis Technique (FAT). The FAT method, also called RIFF method (Filtered Windowed Inverse Resolution), allows to identify the force distribution from local vibration field. In order to only identify the external force applied on a structure, it is necessary to quantify the fluid-structure coupling, especially in naval application, where the fluid is heavy. This method can be decomposed in two parts, the first one consists in identifying the fluid-structure coupling and the second one to introduced it in the FAT method to reconstruct the external force. Results of simulations on a plate coupled with a cavity filled with water are presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aeroacoustics" title="aeroacoustics">aeroacoustics</a>, <a href="https://publications.waset.org/abstracts/search?q=fluid-structure%20coupling" title=" fluid-structure coupling"> fluid-structure coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=inverse%20methods" title=" inverse methods"> inverse methods</a>, <a href="https://publications.waset.org/abstracts/search?q=naval" title=" naval"> naval</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulent%20flow" title=" turbulent flow"> turbulent flow</a> </p> <a href="https://publications.waset.org/abstracts/58380/introduction-of-the-fluid-structure-coupling-into-the-force-analysis-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58380.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">518</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">209</span> "Epitaph" Charles Mingus’ Foresight of Jazz</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christel%20Elisabeth%20Bonin">Christel Elisabeth Bonin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The score of the 2 ½ hour ‘magnum opus’ named ‘Epitaph’ was reconstructed 10 years after Charles Mingus’ death in 1979. Most of the movements were probably composed in the late 1950s. As the finale was missing, Gunther Schuller, the conductor of the world premiere in 1989, decided to improvise one with the orchestra, using Mingus as a guide. The aim of this paper is to analyze ‘Main Score Part I ‘ and ‘Main Score Part II’ and to look into the score of Mingus’ reconstructed compositions under particular observation of the new finale, ‘Main Score Reprise’. There, Mingus left instructions for a return to the opening section of ‘Epitaph’. By examining ‘Epitaph’ in the historical context of Jazz between 1955 to 1967 and the 1980s and comparing the finale of ‘Epitaph’, created - or better said: improvised - by the musicians of the 1989 world premiere with the opening section, at first it will be interesting to discover at which point Gunther Schuller followed Mingus creative process and brought it to life in 1989. Finally, it will be speculated if Charles Mingus composition still represents a foresight of Jazz nearly 30 years after its creation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epitaph" title="epitaph">epitaph</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20Mingus" title=" Charles Mingus"> Charles Mingus</a>, <a href="https://publications.waset.org/abstracts/search?q=Gunter%20Schuller" title=" Gunter Schuller"> Gunter Schuller</a>, <a href="https://publications.waset.org/abstracts/search?q=jazz%20reception" title=" jazz reception"> jazz reception</a>, <a href="https://publications.waset.org/abstracts/search?q=bebop" title=" bebop"> bebop</a>, <a href="https://publications.waset.org/abstracts/search?q=hardbop" title=" hardbop"> hardbop</a>, <a href="https://publications.waset.org/abstracts/search?q=Duke%20Ellington" title=" Duke Ellington"> Duke Ellington</a>, <a href="https://publications.waset.org/abstracts/search?q=black" title=" black"> black</a>, <a href="https://publications.waset.org/abstracts/search?q=brown%20and%20beige" title=" brown and beige"> brown and beige</a>, <a href="https://publications.waset.org/abstracts/search?q=African-American%20music" title=" African-American music"> African-American music</a>, <a href="https://publications.waset.org/abstracts/search?q=free-jazz" title=" free-jazz"> free-jazz</a> </p> <a href="https://publications.waset.org/abstracts/41947/epitaph-charles-mingus-foresight-of-jazz" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41947.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">314</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">208</span> Numerical Simulations of Acoustic Imaging in Hydrodynamic Tunnel with Model Adaptation and Boundary Layer Noise Reduction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sylvain%20Amailland">Sylvain Amailland</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Hugh%20Thomas"> Jean-Hugh Thomas</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20P%C3%A9zerat"> Charles Pézerat</a>, <a href="https://publications.waset.org/abstracts/search?q=Romuald%20Boucheron"> Romuald Boucheron</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Claude%20Pascal"> Jean-Claude Pascal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The noise requirements for naval and research vessels have seen an increasing demand for quieter ships in order to fulfil current regulations and to reduce the effects on marine life. Hence, new methods dedicated to the characterization of propeller noise, which is the main source of noise in the far-field, are needed. The study of cavitating propellers in closed-section is interesting for analyzing hydrodynamic performance but could involve significant difficulties for hydroacoustic study, especially due to reverberation and boundary layer noise in the tunnel. The aim of this paper is to present a numerical methodology for the identification of hydroacoustic sources on marine propellers using hydrophone arrays in a large hydrodynamic tunnel. The main difficulties are linked to the reverberation of the tunnel and the boundary layer noise that strongly reduce the signal-to-noise ratio. In this paper it is proposed to estimate the reflection coefficients using an inverse method and some reference transfer functions measured in the tunnel. This approach allows to reduce the uncertainties of the propagation model used in the inverse problem. In order to reduce the boundary layer noise, a cleaning algorithm taking advantage of the low rank and sparse structure of the cross-spectrum matrices of the acoustic and the boundary layer noise is presented. This approach allows to recover the acoustic signal even well under the boundary layer noise. The improvement brought by this method is visible on acoustic maps resulting from beamforming and DAMAS algorithms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acoustic%20imaging" title="acoustic imaging">acoustic imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=boundary%20layer%20noise%20denoising" title=" boundary layer noise denoising"> boundary layer noise denoising</a>, <a href="https://publications.waset.org/abstracts/search?q=inverse%20problems" title=" inverse problems"> inverse problems</a>, <a href="https://publications.waset.org/abstracts/search?q=model%20adaptation" title=" model adaptation"> model adaptation</a> </p> <a href="https://publications.waset.org/abstracts/58399/numerical-simulations-of-acoustic-imaging-in-hydrodynamic-tunnel-with-model-adaptation-and-boundary-layer-noise-reduction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58399.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">335</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">207</span> Satire of Victorian Mores in Charles Dickens’ Great Expectations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nagwa%20Abouserie%20Soliman">Nagwa Abouserie Soliman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Victorian era, which started with the reign of Queen Victoria from June 1837 to January 1901, could be considered as one of the most significant eras that had a crucial impact which formed contemporary British life despite the fact that with the rise of the British empire many negative aspects surfaced, namelysocial inequalities such as class differences, child labor, population increase and poverty due to the industrial revolution. Charles Dickens was one of the most prominent writers of the Victorian era who perceived the hypocrisy of the Victorian mores. The appropriate researchstyle that was chosen for this literary analysis is a qualitative research method in which the researcher used the conceptual approach to analyse theDickensian characterisation andwriting style through diction, narrative voice, and images. The aim of this paper is to argue that Charles Dickens inGreat Expectations (1861) was highly satirical of the Victorian mores, as he uses a lot of sharp irony-to satirize various Victorian traditions such as class divisions, the justice system, the poor working class, and the upper-class snobbery that he thought are inhumane and unjust. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=victorian" title="victorian">victorian</a>, <a href="https://publications.waset.org/abstracts/search?q=child%20labour" title=" child labour"> child labour</a>, <a href="https://publications.waset.org/abstracts/search?q=poverty" title=" poverty"> poverty</a>, <a href="https://publications.waset.org/abstracts/search?q=class%20division" title=" class division"> class division</a>, <a href="https://publications.waset.org/abstracts/search?q=snobbery" title=" snobbery"> snobbery</a> </p> <a href="https://publications.waset.org/abstracts/148205/satire-of-victorian-mores-in-charles-dickens-great-expectations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148205.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">123</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">206</span> Metamorphosis in Nature through Adéquation: An Ecocritical Reading of Charles Tomlinson's Poetry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Barzegar">Zahra Barzegar</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Deedari"> Reza Deedari</a>, <a href="https://publications.waset.org/abstracts/search?q=Behzad%20Pourgharib"> Behzad Pourgharib</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study examines how metamorphosis in nature is depicted in Charles Tomlinson's poetry through Lawrence Buell's mimesis and referential strategy of adéquation. This study aims to answer the questions that what is the relationship between Tomlinson's selected poems and nature, and how does Tomlinson's poetry bring the reader close to the natural environment. Adéquation is a way that brings the reader close to nature, not by imitating nature but by referring to it imaginatively and creating a stylized image. Using figurative language, namely imagery, metaphor, and analogy, adéquation creates a stylized image of metamorphosis in a nature scene that acts as a middle way between the reader and nature. This paper proves that adéquation reinvents the metamorphosis in natural occurrences in Charles Tomlinson's selected poems. Thus, a reader whose imagination is addressed achieves closeness with nature and a caring outlook toward natural happenings. This article confirms that Tomlinson's poems are potential enough to represent metamorphosis in nature through adéquation. Therefore, the reader understands nature beyond the poem as the poem presents a gist of nature through adéquation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ad%C3%A9quation" title="adéquation">adéquation</a>, <a href="https://publications.waset.org/abstracts/search?q=metamorphosis" title=" metamorphosis"> metamorphosis</a>, <a href="https://publications.waset.org/abstracts/search?q=nature" title=" nature"> nature</a>, <a href="https://publications.waset.org/abstracts/search?q=referentiality" title=" referentiality"> referentiality</a> </p> <a href="https://publications.waset.org/abstracts/144079/metamorphosis-in-nature-through-adequation-an-ecocritical-reading-of-charles-tomlinsons-poetry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144079.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">186</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">205</span> Existential Absurdity, Alienation and Death in Charles Forsman’s The End of the Fxxxing World, I Am Not Okay With This, and Slasher </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Renukha%20Devi%20Anandan">Renukha Devi Anandan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Charles Forsman’s The End of The Fxxxing World, I Am Not Okay With This, and Slasher invariably deals with existential themes. They reflect the perplexed situation of the characters torn between the search for existence and the constraints of human conditions that impede them from such realization, ensuing a dilemma deeply-rooted in absurdity and alienation. These characters are social misfits who fail to fashion their existence and develop harmoniously. Therefore, the present paper adopts an Existential approach to examine the vignettes of alienation and absurdity vis-à-vis the characters’ speech, actions, and thoughts. Furthermore, this paper explores the role of death either as a self-destructive behavior or the eternal freedom of man in graphic novels. Findings portrayed how the characters’ absurd existence surrounded by the void, would eventually develop into death. Finally, the study revealed that Forsman’s distinctive serial illustration not only unveiled the predicaments of the characters through their hard-boiled smokescreens in the 21st-century social paradigm but also established graphic novels as part and parcel of a literary genre. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=existentialism" title="existentialism">existentialism</a>, <a href="https://publications.waset.org/abstracts/search?q=absurdity" title=" absurdity"> absurdity</a>, <a href="https://publications.waset.org/abstracts/search?q=alienation" title=" alienation"> alienation</a>, <a href="https://publications.waset.org/abstracts/search?q=death" title=" death"> death</a>, <a href="https://publications.waset.org/abstracts/search?q=self-destruction" title=" self-destruction"> self-destruction</a>, <a href="https://publications.waset.org/abstracts/search?q=eternal%20freedom" title=" eternal freedom "> eternal freedom </a> </p> <a href="https://publications.waset.org/abstracts/128617/existential-absurdity-alienation-and-death-in-charles-forsmans-the-end-of-the-fxxxing-world-i-am-not-okay-with-this-and-slasher" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128617.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">204</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">204</span> The Play Street: A Community Treat for Psychosocial Replete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benjamin%20Cramer">Benjamin Cramer</a>, <a href="https://publications.waset.org/abstracts/search?q=Josephine%20Chau"> Josephine Chau</a>, <a href="https://publications.waset.org/abstracts/search?q=Helen%20Little"> Helen Little</a>, <a href="https://publications.waset.org/abstracts/search?q=Erica%20Randle"> Erica Randle</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Play Streets provide a safe and open space for children to play and adults to socialize by closing residential streets to through traffic. While research on Play Streets has typically focused on physical activity outcomes in children, there is limited research on the psychosocial health externalities for the wider community. Charles Sturt, a local government area in Adelaide, South Australia, has been hosting Play Streets for several years. The current study is a mixed-methods evaluation of the Charles Sturt Play Streets, concerned with the perceived psychological and social impacts that Play Streets impact on the community. A combination of semi-structured interviews of Play Street organizers and participants will be conducted and analyzed using inductive thematic analysis. Pre-existing survey data will also be analyzed quantitatively and qualitatively to triangulate the findings of the qualitative interviews. The implications of this research are far-reaching, from informing local councils of any additional health benefits of Play Streets, expanding the growing literature on Play Streets beyond childhood physical activity, informing the development of city infrastructure, and advancing the Sustainability Development Goals of Good Health and Wellbeing, Reduced Inequalities, and Sustainable Cities and Communities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=play%20streets" title="play streets">play streets</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20health" title=" mental health"> mental health</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20health" title=" social health"> social health</a>, <a href="https://publications.waset.org/abstracts/search?q=community%20health" title=" community health"> community health</a> </p> <a href="https://publications.waset.org/abstracts/171938/the-play-street-a-community-treat-for-psychosocial-replete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171938.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">82</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">203</span> Identity Crisis and Class Difference in Charles Dickens' 'Great Expectations'</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ramin%20Barati">Ramin Barati</a>, <a href="https://publications.waset.org/abstracts/search?q=Atefeh%20Salemi"> Atefeh Salemi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Victorian era, the society had been surrounded by extreme class ranking in order to identify the people of the classes and to intensify power relationships due to the growth of industry in Charles Dickens's (1812-1870) Great Expectations (2003) in which he illustrates the clash and dichotomy in the 19th century London. The classes in Victorian period have socially divided the population into two parts, the lower and the upper class of the community. In such a panopticon society, the major character Pip was the best example of the working class who was under the domination of violence, malice, and abuse of Miss Havisham as a member of the ruling class in order to take revenge on her failures. The conflict and disunity represented in vindictiveness and the sense of revenge applied by Miss Havisham against his victim Pip, made him experience alienation and eventually suffer from identity crisis. This paper considers New Historicism based on the theories of the French critic Michel Foucault (1926-1984). The social concept, panopticism, was called after the panopticon society, basically elaborated by Foucault in his book Discipline and Punish (1975) and he considers the panopticon as a sign of punitive community of surveillance. This paper evaluates the problems of a dual society to show that the people of the lower class are under the domination of capitalist society. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=class" title="class">class</a>, <a href="https://publications.waset.org/abstracts/search?q=identity%20crisis" title=" identity crisis"> identity crisis</a>, <a href="https://publications.waset.org/abstracts/search?q=violence" title=" violence"> violence</a>, <a href="https://publications.waset.org/abstracts/search?q=panoptic%20society" title=" panoptic society"> panoptic society</a>, <a href="https://publications.waset.org/abstracts/search?q=domination" title=" domination"> domination</a> </p> <a href="https://publications.waset.org/abstracts/97813/identity-crisis-and-class-difference-in-charles-dickens-great-expectations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97813.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">239</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">202</span> Visualising Charles Bonnet Syndrome: Digital Co-Creation of Pseudohallucinations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victoria%20H.%20Hamilton">Victoria H. Hamilton</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Charles Bonnet Syndrome (CBS) is when a person experiences pseudohallucinations that fill in visual information from any type of sight loss. CBS arises from an epiphenomenal process, with the physical actions of sight resulting in the mental formations of images. These pseudohallucinations—referred to as visions by the CBS community—manifest in a wide range of forms, from complex scenes to simple geometric shapes. To share these unique visual experiences, a remote co-creation website was created where CBS participants communicated their lived experiences. This created a reflexive process, and we worked to produce true representations of these interesting and little-known phenomena. Digital reconstruction of the visions is utilised as it echoes the vivid, experiential movie-like nature of what is being perceived. This paper critically analyses co-creation as a method for making digital assets. The implications of the participants' vision impairments and the application of ethical safeguards are examined in this context. Important to note, this research is of a medical syndrome for a non-medical, practice-based design. CBS research to date is primarily conducted by the ophthalmic, neurological, and psychiatric fields and approached with the primary concerns of these specialties. This research contributes a distinct approach incorporating practice-based digital design, autoethnography, and phenomenology. Autoethnography and phenomenology combine as a foundation, with the first bringing understanding and insights, balanced by the second philosophical, bigger picture, and established approach. With further refining, it is anticipated that the research may be applied to other conditions. Conditions where articulating internal experiences proves challenging and the use of digital methods could aid communication. Both the research and CBS communities will benefit from the insights regarding the relationship between cognitive perceptions and the vision process. This research combines the digital visualising of visions with interest in the link between metaphor, embodied cognition, and image. The argument for a link between CBS visions and metaphor may appear evident due to the cross-category mapping of images that is necessary for comprehension. They both are— CBS visions and metaphors—the experience of picturing images, often with lateral connections and imaginative associations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Charles%20Bonnet%20Syndrome" title="Charles Bonnet Syndrome">Charles Bonnet Syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20design" title=" digital design"> digital design</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20hallucinations" title=" visual hallucinations"> visual hallucinations</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20perception" title=" visual perception"> visual perception</a> </p> <a href="https://publications.waset.org/abstracts/184568/visualising-charles-bonnet-syndrome-digital-co-creation-of-pseudohallucinations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184568.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">44</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">201</span> Ameliorative Effect of Curcuma Longa against Arsenic Induced Reproductive Toxicity in Charles Foster Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shazia%20Naheed%20Akhter">Shazia Naheed Akhter</a>, <a href="https://publications.waset.org/abstracts/search?q=Rekha%20Kumari"> Rekha Kumari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An estimated 70 million population are exposed to arsenic poisoning in India in recent times. Arsenic contamination in the groundwater has caused serious health hazards among the exposed population. In Bihar, the first district was Bhojpur, where arsenic causing health issues were reported in 2002. Presently, there are 18 districts that are reported arsenic poisoning in the groundwater. The exposed population is firstly diseased with various symptoms such as skin manifestations, loss of appetite, constipation, hormonal disorders, etc. The long duration exposure has led to cause infertility in the male subjects. The present study thus aims to develop the antidote against arsenic-induced male reproductive toxicity in animal models. The study was carried out on Charles Foster Rats after the approval from Institutional Animal Ethics Committee. A total of n=18 rats (12 weeks old) of an average weight of 160 ± 20 g were used for the study. The study group included n=6 control and n= 12 treated with sodium arsenite orally at the dose of 8mg/Kg b.w daily for 40 days. The n= 6 animals were dissected and the rest n=6 was administered orally with Curcuma longa rhizome ethanolic extract at the dose of 600mg/Kg b.w per day for 40 days. At the end of the entire experiment, all the animals were dissected out and their reproductive organs were taken out, especially epididymis for sperm counts, sperm motility, sperm mortality, sperm morphology. The blood samples were collected for the hormonal assay (testosterone and luteinizing hormone), as well as for hematological and biochemical analysis. The study showed a high magnitude of degeneration in the reproductive organs of the rats in the arsenic-treated group. There were degenerative fluctuations in the sperm counts, sperm motility, sperm mortality, sperm morphology and in the hormonal parameters, as well as in the hematological and biochemical parameters in the arsenic-treated rats. But, after the administration of Curcuma longa, there was significant amelioration in all these parameters. Therefore, the present study shows that Curcuma longa plays a vital role to combat arsenic-induced male reproductive toxicity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sodium%20arsenite" title="sodium arsenite">sodium arsenite</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20foster%20rats" title=" Charles foster rats"> Charles foster rats</a>, <a href="https://publications.waset.org/abstracts/search?q=ethanolic%20rhizome%20extract%20of%20curcuma%20longa" title=" ethanolic rhizome extract of curcuma longa"> ethanolic rhizome extract of curcuma longa</a>, <a href="https://publications.waset.org/abstracts/search?q=male%20reproductive%20toxicity" title=" male reproductive toxicity"> male reproductive toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=amelioration" title=" amelioration"> amelioration</a> </p> <a href="https://publications.waset.org/abstracts/139480/ameliorative-effect-of-curcuma-longa-against-arsenic-induced-reproductive-toxicity-in-charles-foster-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139480.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">223</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">200</span> The Science of Dreaming and Sleep in Selected Charles Dickens' Novels and Letters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olga%20Colbert">Olga Colbert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present work examines the representation of dreaming in Charles Dickens’ novels, particularly Oliver Twist. Dickens showed great interest in the science of dreaming and had ample knowledge of the latest dream theories in the Victorian era, as can be seen in his personal correspondence, most notably in his famous letter to Dr. Thomas Stone on 2/2/1851. This essay places Dickens’ personal writings side by side with his novels to elucidate whether the scientific paradigm about dreaming included in the novel is consistent with the current (in Dickens’ time) scientific knowledge, or whether it is anachronistic or visionary (ahead of his time). Oliver Twist is particularly useful because it contains entire passages pondering on the nature of dreaming, enumerating types of common dreams, and taking a stand on the interference of sensory perception during the dreaming state. The author is particularly intrigued by Dickens’ assumption of the commonality and universality of lucid dreaming as revealed in these passages. This essay places popular Victorian dream theories, such as those contained in Robert Macnish’s The Philosophy of Sleep, side by side with recent dream theory, particularly psychophysiologist Stephen LaBerge’s numerous articles and books on the topic of lucid dreaming to see if Dickens deviated in any way from the reigning paradigm of the Victorian era in his representation of dreaming in his novels. While Dickens puts to great narrative use many of the characteristics of dreaming described by leading Victorian theorists, the author of this study argues, however, that Dickens’ most visionary statements derive from his acute observations of his own dreaming experiences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=consciousness" title="consciousness">consciousness</a>, <a href="https://publications.waset.org/abstracts/search?q=Dickens" title=" Dickens"> Dickens</a>, <a href="https://publications.waset.org/abstracts/search?q=dreaming" title=" dreaming"> dreaming</a>, <a href="https://publications.waset.org/abstracts/search?q=lucid%20dreaming" title=" lucid dreaming"> lucid dreaming</a>, <a href="https://publications.waset.org/abstracts/search?q=Victorian" title=" Victorian"> Victorian</a> </p> <a href="https://publications.waset.org/abstracts/70169/the-science-of-dreaming-and-sleep-in-selected-charles-dickens-novels-and-letters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70169.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">289</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">199</span> Predictive Factors of Healthcare-Associated Infections and Antibiotic Use Patterns: A Cross-Sectional Survey at the Charles Nicolle Hospital of Tunis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nouira%20Mariem">Nouira Mariem</a>, <a href="https://publications.waset.org/abstracts/search?q=Ennigrou%20Samir"> Ennigrou Samir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and aims: Healthcare-associated infections (HAI) represent a major public health problem worldwide. They represent one of the most serious adverse events in health care. The objectives of our study were to estimate the prevalence of HAI at the Charles Nicolle Hospital (CNH) and to identify the main associated factors as well as to estimate the frequency of antibiotic use. Methods: It was a cross-sectional study at the CNH with a unique passage per department (October-December 2018). All patients present at the wards for more than 48 hours were included. All patients from outpatient consultations, emergency, and dialysis departments were not included. The site definitions of infections proposed by the Centers for Disease Control and Prevention (CDC) were used. Only clinically and/or microbiologically confirmed active HAIs were included. Results: A total of 318 patients were included, with a mean age of 52 years and a sex ratio (female/male) of 1.05. A total of 41 patients had one or more active HAIs, corresponding to a prevalence of 13.1% (95% CI: 9.3%-16.9%). The most frequent site infections were urinary tract infections and pneumonia. Multivariate analysis among adult patients (>=18 years) (n=261) revealed that infection on admission (p=0.01), alcoholism (p=0.01), high blood pressure (p=0.008), having at least one invasive device inserted (p=0.004), and history of recent surgery (p=0.03), increased the risk of HAIs significantly. More than 1 of 3 patients (35.4%) were under antibiotics on the day of the survey, of which more than half (57.4%) were under two or more types of antibiotics. Conclusion: The prevalence of HAIs and antibiotic prescriptions at the CNH were considerably high. An infection prevention and control committee, as well as the development of an antibiotic stewardship program with continuous monitoring using repeated prevalence surveys, must be implemented to limit the frequency of these infections effectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=prevalence" title="prevalence">prevalence</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare%20associated%20infection" title=" healthcare associated infection"> healthcare associated infection</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotic" title=" antibiotic"> antibiotic</a>, <a href="https://publications.waset.org/abstracts/search?q=Tunisia" title=" Tunisia"> Tunisia</a> </p> <a href="https://publications.waset.org/abstracts/164407/predictive-factors-of-healthcare-associated-infections-and-antibiotic-use-patterns-a-cross-sectional-survey-at-the-charles-nicolle-hospital-of-tunis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164407.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">82</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">198</span> Sudan’s Approach to Knowledge Management in Disaster Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Abdalla%20Elamein%20Boshara">Mohamed Abdalla Elamein Boshara</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Charles%20Woods"> Peter Charles Woods</a>, <a href="https://publications.waset.org/abstracts/search?q=Nour%20Eldin%20Mohamed%20Elshaiekh"> Nour Eldin Mohamed Elshaiekh </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Knowledge Management has become very important for Disaster Management response and planning.

A number of 246 seropositive patients were examined by the laboratory of Prince Regent Charles in the period between 2010 and 2015. We did a retrospective study; we used data from the registers of the laboratories mentioned above; the objective was to approach the epidemiological, biological, clinical, and therapeutic characteristics of tuberculosis meningitis infection: 124 women (50.40% of AIDS patients) and 122 men (49.59% of AIDS patients) were subject to the diagnosis by identification of cerebrospinal fluid (CSF). The average age of the patients was 30 years for this period. The population at risk has an average age of between 34 and 42 years for the years between 2010-2015. From 2010 to 2012, cases of opportunistic diseases (e.g., tuberculous meningitis and Cryptococcus neoformans meningitis), often found in immunocompromised, were observed at a high rate; in this period, there was a disturbance of the rhythm providing antiretroviral drugs to people with AIDS. The rate of the two meningitis (tuberculous meningitis and Cryptococcus neoformans meningitis) remained above 10% to gradually decrease until 2015, with the gradual return of antiretrovirals. This period records an overall average of 25 cases of tuberculous meningitis, or a percentage of 10.16%. For the year 2015, there were 4 cases of tuberculous meningitis out of a total of 35 seropositive examined (11.42%). This year's percentage shows that the number of tuberculous meningitis cases has fallen from the rate in previous years. This is the result of the care given by associations against HIV/AIDS to HIV-positive people. This decrease in cases of tuberculous meningitis is due to the acquisition of antiretrovirals by all HIV-positive people treated by hospitals. For the moment, these hospitals are taking care of many AIDS patients by providing them permanently with antiretrovirals; Besides that, there are many patients who are supported by associations whose activities are directed against HIV/AIDS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cryptococcus%20neoformans%20meningitis" title="Cryptococcus neoformans meningitis">Cryptococcus neoformans meningitis</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculosis%20meningitis" title=" tuberculosis meningitis"> tuberculosis meningitis</a>, <a href="https://publications.waset.org/abstracts/search?q=neurological%20complications" title=" neurological complications"> neurological complications</a>, <a href="https://publications.waset.org/abstracts/search?q=epidemiology%20of%20meningitis" title=" epidemiology of meningitis"> epidemiology of meningitis</a> </p> <a href="https://publications.waset.org/abstracts/138470/neurological-complications-of-hivaids-case-of-meningitis-caused-by-cryptococcus-neoformans-and-tuberculous-meningitis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138470.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">223</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">196</span> Improving the Efficiency of Pelton Wheel and Cross-Flow Micro Hydro Power Plants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Loice%20K.%20Gudukeya">Loice K.

The system of prefabrication invented by Ford had inspired them to try to create a system or prototype that could become the basis for the mass 'production' of houses. The attempts made by Le Corbusier, Buckminster Fuller or Charles and Ray Eames, among others, are well known in this regard. The economic attractiveness of replicable, mass-producible houses meant that experiments in this area were undertaken in both the West and the East. Among such attempts was the project of dome-shaped houses conceived by the architect and inventor Andrzej Iwanicki and realised between 1961 and 1966 in Warsaw's Okęcie district on Ustrzycka Street. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dome%20houses" title="dome houses">dome houses</a>, <a href="https://publications.waset.org/abstracts/search?q=polish%20modernism" title=" polish modernism"> polish modernism</a>, <a href="https://publications.waset.org/abstracts/search?q=postwar%20modernism" title=" postwar modernism"> postwar modernism</a>, <a href="https://publications.waset.org/abstracts/search?q=modernist%20houses" title=" modernist houses"> modernist houses</a> </p> <a href="https://publications.waset.org/abstracts/167147/between-an-idea-and-the-experiment-dome-houses-in-warsaw" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167147.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">108</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">189</span> Parallel 2-Opt Local Search on GPU</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wen-Bao%20Qiao">Wen-Bao Qiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Charles%20Cr%C3%A9put"> Jean-Charles Créput</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To accelerate the solution for large scale traveling salesman problems (TSP), a parallel 2-opt local search algorithm with simple implementation based on Graphics Processing Unit (GPU) is presented and tested in this paper.

From the United States’ Endangered Species Act to the European Union’s conservation policies to the International Union for the Conservation of Nature’s Red List, hybrids don’t get the benefit of human preservation efforts. This paper tests the hypothesis that this practice is a byproduct of the co-birth of eugenics and conservation as twin fields and that while the first has been discredited and abandoned, the latter still bears the marks of its unfortunate primordial association. The research explores historical perspectives from so-called conservation luminaries such as Madison Grant, Ernst Mayr, and Charles Davenport and sheds light on how these influences continue to shape contemporary conservation approaches. The paper provides a comprehensive analysis of the implications of these factors on biodiversity conservation and the ethical considerations surrounding hybrid species protection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conservation" title="conservation">conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=hybridization" title=" hybridization"> hybridization</a>, <a href="https://publications.waset.org/abstracts/search?q=eugenics" title=" eugenics"> eugenics</a>, <a href="https://publications.waset.org/abstracts/search?q=speciation" title=" speciation"> speciation</a>, <a href="https://publications.waset.org/abstracts/search?q=evolution" title=" evolution"> evolution</a> </p> <a href="https://publications.waset.org/abstracts/173191/undeserving-hybrids-the-enduring-legacy-of-eugenics-in-conservation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173191.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">90</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">187</span> The Power of the Proper Orthogonal Decomposition Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Charles%20Lee">Charles Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Principal Orthogonal Decomposition (POD) technique has been used as a model reduction tool for many applications in engineering and science. In principle, one begins with an ensemble of data, called snapshots, collected from an experiment or laboratory results. The beauty of the POD technique is that when applied, the entire data set can be represented by the smallest number of orthogonal basis elements. It is the such capability that allows us to reduce the complexity and dimensions of many physical applications.

This problem will have its importance increase due to the shift in the production mode that modern society is going through. The demands are increasing and for products personalized and customized. This work aims to apply a meta-heuristic called a genetic algorithm (GA) to solve this problem. A GA is a meta-heuristic inspired by the natural selection of Charles Darwin; it produces a population of individuals (solutions) and selects, mutates, and mates the individuals through generations in order to find a good solution for the problem.

Results of the analysis show that the draft NTP has been used to establish transport schemes, master plans, and transport infrastructure. The paper concludes that though, the national transport Policy is still in a draft form, its production, however, has shaped the transport system in Nigeria and has shown how transport has improved the economy through the efficient utilisation of resources, improved mobility, and lifestyle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=principles" title="principles">principles</a>, <a href="https://publications.waset.org/abstracts/search?q=draft" title=" draft"> draft</a>, <a href="https://publications.waset.org/abstracts/search?q=system" title=" system"> system</a>, <a href="https://publications.waset.org/abstracts/search?q=resources" title=" resources"> resources</a> </p> <a href="https://publications.waset.org/abstracts/168700/a-review-of-the-fundamental-principles-of-the-national-transport-policy-and-developmental-implementation-programmes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168700.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">141</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">184</span> Acoustic Room Impulse Response Computation with Image Sources and Frequency Dependent Boundary Reflection Coefficients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pratik%20Gandhi">Pratik Gandhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kavitha%20Chandra"> Kavitha Chandra</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20Thompson"> Charles Thompson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A computational model of the acoustic room impulse response between transmitters and receivers located in an enclosed cavity under the influence of frequency-dependent reflection coefficients of the walls is presented.

Test results indicated that the inclusion of poly-lactic acid decreased the PH value of concrete and all the poly-lactic acid particles were dissolved due to the formation of sodium lactide and lactide oligomers when subjected to the high alkaline environment of concrete. In addition, an increase in thermal conductivity value of concrete was observed as the ratio of poly-lactic acid increased.
