Sizing of components follows the Bradley cabin sizing and rubber engine scaling procedures to size the cabin and engine respectively. The interference detection and avoidance algorithm relies on the ability of the Class Shape Transform parameterisation technique to generate polynomial functions of the surfaces of a BWB aircraft configuration from the sizes of the cabin and internal objects using few variables. Interference detection is essential in packaging of non-conventional configuration like the BWB because of the non-uniform airfoil-shaped sections and resultant varying internal space. The unique configuration increases the need for a methodology to prevent objects from being placed in locations that do not sufficiently enclose them within the geometry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=packaging" title="packaging">packaging</a>, <a href="https://publications.waset.org/abstracts/search?q=optimisation" title=" optimisation"> optimisation</a>, <a href="https://publications.waset.org/abstracts/search?q=BWB" title=" BWB"> BWB</a>, <a href="https://publications.waset.org/abstracts/search?q=parameterisation" title=" parameterisation"> parameterisation</a>, <a href="https://publications.waset.org/abstracts/search?q=aircraft%20conceptual%20design" title=" aircraft conceptual design"> aircraft conceptual design</a> </p> <a href="https://publications.waset.org/abstracts/33498/packaging-in-the-design-synthesis-of-novel-aircraft-configuration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33498.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">463</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">488</span> Running the Athena Vortex Lattice Code in JAVA through the Java Native Interface</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paul%20Okonkwo">Paul Okonkwo</a>, <a href="https://publications.waset.org/abstracts/search?q=Howard%20Smith"> Howard Smith</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes a methodology to integrate the Athena Vortex Lattice Aerodynamic Software for automated operation in a multivariate optimisation of the Blended Wing Body Aircraft.

H. Lawrence's 'Sons and Lovers'</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chaich%20Hamza%20Walid">Chaich Hamza Walid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The primary goal of this paper is to question the situation of men’s place in D.H Lawrence’s Sons and Lovers. Our question is what is the role of each man in the novel? And how a mother’s possessiveness had changed the life of all men in the family? David Herbert Lawrence was an important and controversial English writer of the 20th century. He wrote many great works, one of his most popular novels, Sons and Loves, is an autobiographical account of his youth. This novel is about the life of the Morels. The author develops the story by portraying the relationships between many characters, especially the male ones we focus on. ‘Sons and Lovers’ seems to be written especially to women, all what Lawrence wrote is about women but when we go deeper, we see that Lawrence was also interested in men. This work will approach the question in two ways. The first chapter will deal with men’s place in D.H Lawrence’s Sons and Lovers, more exactly with Paul and his father Walter Morel, and with Baxter Dawes. We will focus on each man’s behavior with one another. In the second chapter, we will analyze possessiveness, that is to say, the desire of holding or having someone as one’s own or under one’s control. We will try to prove this view from the spiritual and symbolic possession of different relationships. Our study will be through an intensive psychological analysis of a wife’s possessiveness to her husband, and a mother’s possessiveness to her son’s; William and Paul. The conclusion will review all the important aspects of this analysis. It is very important to know about men’s relationships in D.H Lawrence’s Sons and Lovers this will give us another vision of the novel, and where we can situate Paul’s true relationships, that is to say, his relationships with his father and the other men in the novel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=language" title="language">language</a>, <a href="https://publications.waset.org/abstracts/search?q=literature" title=" literature"> literature</a>, <a href="https://publications.waset.org/abstracts/search?q=English" title=" English"> English</a>, <a href="https://publications.waset.org/abstracts/search?q=civilisation" title=" civilisation"> civilisation</a> </p> <a href="https://publications.waset.org/abstracts/43722/mens-relationships-in-d-h-lawrences-sons-and-lovers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43722.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">461</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">484</span> Internet as a Marketing Tool for Tourism Promotion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emeka%20Okonkwo">Emeka Okonkwo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Information Technology (IT) has prevailed over all functions of strategic and operational management. The Internet (a product of information technology) has increasingly become a popular medium for marketing. This paper examines the potentials of Internet for tourism marketing. To achieve this, the paper x-rays the characteristics of tourism marketing and examines the application of the Internet in tourism marketing. It is argued that the use of Internet for tourism marketing will not only reach a broad audience and reduce the cost of transaction (by conventional methods used by travel agents in times past), but, will also alleviate the problems of identification, authentication and confirmation of travels/package tours by tourists as well as promotion of tourism industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internet" title="internet">internet</a>, <a href="https://publications.waset.org/abstracts/search?q=marketing" title=" marketing"> marketing</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism" title=" tourism"> tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism%20management" title=" tourism management"> tourism management</a> </p> <a href="https://publications.waset.org/abstracts/6055/internet-as-a-marketing-tool-for-tourism-promotion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6055.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">419</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">483</span> Gaussian Operations with a Single Trapped Ion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bruna%20G.%20M.%20Ara%C3%BAjo">Bruna G.

Analyzing a single ion locked in a Paul trap we use the interaction picture to obtain a toolbox of Gaussian operations with the ion-laser interaction Hamiltionian. This is achieved exciting the ion through the combination of two lasers of distinct frequencies corresponding to different sidebands of the external degrees of freedom. First we study the case of a trap with 1 mode and then the case with 2 modes. In this way, we achieve different continuous variables gates just by changing the external degrees of freedom of the trap and combining the Hamiltonians of blue and red sidebands. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paul%20trap" title="Paul trap">Paul trap</a>, <a href="https://publications.waset.org/abstracts/search?q=ion-laser%20interaction" title=" ion-laser interaction"> ion-laser interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=Gaussian%20operations" title=" Gaussian operations"> Gaussian operations</a> </p> <a href="https://publications.waset.org/abstracts/18445/gaussian-operations-with-a-single-trapped-ion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18445.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">686</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">482</span> Cross Analysis of Gender Discrimination in Print Media of Subcontinent via James Paul Gee Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luqman%20Shah">Luqman Shah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The myopic gender discrimination is now a well-documented and recognized fact. However, gender is only one facet of an individual’s multiple identities. The aim of this work is to investigate gender discrimination highlighted in print media in the subcontinent with a specific focus on Pakistan and India. In this study, an approach is adopted by using the James Paul Gee model for the identification of gender discrimination. As a matter of fact, gender discrimination is not consistent in its nature and intensity across global societies and varies as social, geographical, and cultural background change. The World has been changed enormously in every aspect of life, and there are also obvious changes towards gender discrimination, prejudices, and biases, but still, the world has a long way to go to recognize women as equal as men in every sphere of life. The history of the world is full of gender-based incidents and violence. Now the time came that this issue must be seriously addressed and to eradicate this evil, which will lead to harmonize society and consequently heading towards peace and prosperity. The study was carried out by a mixed model research method. The data was extracted from the contents of five Pakistani English newspapers out of a total of 23 daily English newspapers, and likewise, five Indian daily English newspapers out of 52 those were published 2018-2019. Two news stories from each of these newspapers, in total, twenty news stories were taken as sampling for this research. Content and semiotic analysis techniques were used to analyze through James Paul Gee's seven building tasks of language. The resources of renowned e-papers are utilized, and the highlighted cases in Pakistani newspapers of Indian gender-based stories and vice versa are scrutinized as per the requirement of this research paper. For analysis of the written stretches of discourse taken from e-papers and processing of data for the focused problem, James Paul Gee 'Seven Building Tasks of Language' is used. Tabulation of findings is carried to pinpoint the issue with certainty. Findings after processing the data showed that there is a gross human rights violation on the basis of gender discrimination. The print media needs a more realistic representation of what is what not what seems to be. The study recommends the equality and parity of genders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender%20discrimination" title="gender discrimination">gender discrimination</a>, <a href="https://publications.waset.org/abstracts/search?q=print%20media" title=" print media"> print media</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Gee%20model" title=" Paul Gee model"> Paul Gee model</a>, <a href="https://publications.waset.org/abstracts/search?q=subcontinent" title=" subcontinent"> subcontinent</a> </p> <a href="https://publications.waset.org/abstracts/117683/cross-analysis-of-gender-discrimination-in-print-media-of-subcontinent-via-james-paul-gee-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117683.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">221</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">481</span> The Contribution of the Livestock Marketing Programme in Improving Household Food Security in Communal Areas of Umzimkhulu Local Municipality, Kwa-Zulu Natal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sibongiseni%20Peacock">Sibongiseni Peacock</a>, <a href="https://publications.waset.org/abstracts/search?q=Denver%20Naidoo"> Denver Naidoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Sikhalazo%20Dube"> Sikhalazo Dube</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study investigates the impact of the National Red Meat Development Programme on household food security in rural areas of uMzimkhulu. Self-administered questionnaires were employed to gather data from 77 smallholder beef farmers participating in the St. Paul feedlot project. Data analysis utilized the Household Food Insecurity Access Scale (HFIAS) developed by USAID to assess the household food security status of St. Paul feedlot beneficiaries, with descriptive statistics employed for result analysis. Findings indicate that the majority (80.50%) of beneficiaries experienced food insecurity, while (19.50%) were classified as food secure, with most participants falling within the category of moderate food insecurity. Food insecurity predominantly stemmed from challenges faced by farmers unable to sell their cattle or whose cattle were not market-ready due to bureaucratic obstacles hindering the programme. Farmers identified feed shortages as the primary constraint, resulting in missed income opportunities. These findings underscore the critical need to address feed challenges and bureaucratic barriers to enhance the efficacy of the National Red Meat Development Programme in promoting household food security in rural areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=National%20Red%20Meat%20Development" title="National Red Meat Development">National Red Meat Development</a>, <a href="https://publications.waset.org/abstracts/search?q=household%20food%20security" title=" household food security"> household food security</a>, <a href="https://publications.waset.org/abstracts/search?q=St.%20Paul%20feedlot" title=" St. Paul feedlot"> St. Paul feedlot</a>, <a href="https://publications.waset.org/abstracts/search?q=livestock" title=" livestock"> livestock</a>, <a href="https://publications.waset.org/abstracts/search?q=HFIAS" title=" HFIAS"> HFIAS</a> </p> <a href="https://publications.waset.org/abstracts/184622/the-contribution-of-the-livestock-marketing-programme-in-improving-household-food-security-in-communal-areas-of-umzimkhulu-local-municipality-kwa-zulu-natal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184622.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">55</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">480</span> Building an Absurdist Approach to the Philosophy of Science: Combining Camus and Feyerabend</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Robert%20Herold">Robert Herold</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This project aims to begin building out a new approach within the philosophy of science that is based around a combination of insights from Albert Camus and Paul Feyerabend. This approach is one that will be labeled an absurdist approach as it uses, for its foundation, the philosophy of the absurd as discussed by Camus. While Camus didn’t directly discuss the philosophy of science, nor did he offer his own views on the subject in any substantial way, that doesn’t mean that his work doesn’t have applications within the philosophy of science. In fact, as is argued throughout the piece, much of the work done by Paul Feyerabend stems from a similar metaphysical and epistemological foundation as Camus. This foundation is the notion of the absurd and the inability of us as humans to reach some sort of objective truth. In modern times both Camus and Feyerabend have been largely pushed to the wayside, though Feyerabend has undoubtedly received the most unfair treatment of the two, and this is something that serves to act more as a hindrance than anything else. Much of the claims and arguments made by both Camus and Feyerabend have not been truly refuted and have simply been pushed aside by pointing to supposed contradictions or inconsistencies. However, while it would be a monumental task to attempt to discuss all of this past work, perhaps it might be better to move beyond both Camus and Feyerabend and chart a new path. This is the overall goal of this paper. This research will demonstrate that not only are the philosophies of Camus and Feyerabend surprisingly similar and able to mesh well together, they also are able to form into something that is truly more than the sum of its parts. While the task of actually building out an approach is a monumental undertaking, the plan is to use this project as a jumping-off point. As such, this paper will start by examining some of the main claims made by both Camus and Feyerabend. Once this is done, then begin weaving them together and demonstrating where the links between the philosophies of both are. Then this study will end by building out the very begging foundations of the absurdist approach to the philosophy of science. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=philosophy" title="philosophy">philosophy</a>, <a href="https://publications.waset.org/abstracts/search?q=philosophy%20of%20science" title=" philosophy of science"> philosophy of science</a>, <a href="https://publications.waset.org/abstracts/search?q=albert%20camus" title=" albert camus"> albert camus</a>, <a href="https://publications.waset.org/abstracts/search?q=paul%20feyerabend" title=" paul feyerabend"> paul feyerabend</a> </p> <a href="https://publications.waset.org/abstracts/142863/building-an-absurdist-approach-to-the-philosophy-of-science-combining-camus-and-feyerabend" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142863.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">251</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">479</span> Hermitical Landscapes: The Congregation of Saint Paul of Serra De Ossa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rolando%20Volzone">Rolando Volzone</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Congregation of Saint Paul of Serra de Ossa (Ossa Mountain) was founded in 1482, originated by the eremitic movement of the homens da pobre vida (poor life men), which is documented since 1366. The community of hermits expanded up to the first half of the 15th century, mostly in southern Portugal in the Alentejo region. In 1578, following a process of institutionalization led by the Church, an autonomous congregation was set up, affiliated in the Hungarian Order of Saint Paul the First Hermit, until 1834, when the decree of dissolution of the religious orders disbanded all the convents and monasteries in Portugal. The architectural evidences that reached our days as a legacy of the hermitical movement in Serra de Ossa, although studied and analysed from an historical point of view, are still little known with respect to the architectural characteristics of its physical implantation and its relationship with the natural systems. This research intends to expose the appropriation process of the locus eremus as a starting point for the interpretation of this landscape, evidencing the close relationship between the religious experience and the physical space chosen to reach the perfection of the soul. The locus eremus is thus determined not only by practical aspects such as the absolute and relative location, orography, existence of water resources, or the King’s favoring to the religious and settlement action of the hermits, but also by spiritual aspects related to the symbolism of the physical elements present and the solitary walk of these men. These aspects, combined with the built architectural elements and other exerted human action, may be fertile ground for the definition of a hypothetical hermitical landscape based on the sufficiently distinctive characteristics that sustain it. The landscape built by these hermits is established as a cultural and material heritage, and its preservation is of utmost importance. They deeply understood this place and took advantage of its natural resources, manipulating them in an ecological and economically sustainable way, respecting the place, without overcoming its own genius loci but becoming part of it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=architecture" title="architecture">architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=congregation%20of%20Saint%20Paul%20of%20Serra%20de%20Ossa" title=" congregation of Saint Paul of Serra de Ossa"> congregation of Saint Paul of Serra de Ossa</a>, <a href="https://publications.waset.org/abstracts/search?q=heremitical%20landscape" title=" heremitical landscape"> heremitical landscape</a>, <a href="https://publications.waset.org/abstracts/search?q=locus%20eremus" title=" locus eremus"> locus eremus</a> </p> <a href="https://publications.waset.org/abstracts/87294/hermitical-landscapes-the-congregation-of-saint-paul-of-serra-de-ossa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87294.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">234</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">478</span> Enigmatic Identity and Alienated Self: Existential Analysis of Paul Auster's the Brooklyn Follies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sapna%20Bhargav">Sapna Bhargav</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Contemporary fiction is an intricate exercise where novelist acquires the role of a philosopher, a sociologist and a psychologist. The dilemma of fragmented self that a man experiences, is a crucial subject of contemporary fiction. Paul Auster's fiction is exemplary of the merger of Existentialism and Postmodernism, and while both of these movements insist on isolation of the self from all aspects of social affiliation, Auster's unique blend of these concepts presents man in a state which is not just alienated, but stranded in a desolate abyss, rendering even the release of death as questionable. The conundrums of the self is a compulsory consequence of the existentialist alienation that postmodern man is subjected to, and is further accentuated by the fact that existentialist freedom dictates that not only are one's actions not dictated by any form of external entity, but also the onus of one's destiny lies on an individual's own deeds. This paper will analyse Auster's The Brooklyn Follies from an Existentialist perspective, and will attempt to trace the alienation and identity conflicts of the Auster’s characters along with some of the common Austerian themes. An emphasis will be laid on the characters’ endeavour to reconstruct their lost self. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alienation" title="alienation">alienation</a>, <a href="https://publications.waset.org/abstracts/search?q=existentialism" title=" existentialism"> existentialism</a>, <a href="https://publications.waset.org/abstracts/search?q=identity" title=" identity"> identity</a>, <a href="https://publications.waset.org/abstracts/search?q=postmodernism" title=" postmodernism"> postmodernism</a>, <a href="https://publications.waset.org/abstracts/search?q=self" title=" self"> self</a> </p> <a href="https://publications.waset.org/abstracts/21784/enigmatic-identity-and-alienated-self-existential-analysis-of-paul-austers-the-brooklyn-follies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21784.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">591</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">477</span> Adsorption of Cd2+ from Aqueous Solutions Using Chitosan Obtained from a Mixture of Littorina littorea and Achatinoidea Shells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20D.%20Paul">E.

The equilibrium adsorption isotherms were determined between 298 K and 345 K. The adsorption data were adjusted to Langmuir, Freundlich and the pseudo second order kinetic models. It was found that the Langmuir isotherm model most fitted the experimental data, with a maximum monolayer adsorption of 35.1 mgkg⁻¹ at 308 K. The entropy and enthalpy of adsorption were -0.1121 kJmol⁻¹K⁻¹ and -11.43 kJmol⁻¹ respectively. The Freundlich adsorption model, gave Kf and n values consistent with good adsorption. The pseudo-second order reaction model gave a straight line plot with rate constant of 1.291x 10⁻³ kgmg⁻¹ min⁻¹. The qe value was 21.98 mgkg⁻¹, indicating that the adsorption of Cadmium ion by the chitosan composite followed the pseudo-second order kinetic model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=chitosan" title=" chitosan"> chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=littorina%20littorea" title=" littorina littorea"> littorina littorea</a>, <a href="https://publications.waset.org/abstracts/search?q=achatinoidea" title=" achatinoidea"> achatinoidea</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20polymer" title=" natural polymer"> natural polymer</a> </p> <a href="https://publications.waset.org/abstracts/49606/adsorption-of-cd2-from-aqueous-solutions-using-chitosan-obtained-from-a-mixture-of-littorina-littorea-and-achatinoidea-shells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49606.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">404</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">476</span> Job Satisfaction and Commitment among Academic Staff of Selected Colleges of Education in Kano and Kaduna States of Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mary%20Okonkwo%20Ekwy">Mary Okonkwo Ekwy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The problem of the growing disillusionment of College of Education teachers with academic life vis-à-vis their job satisfaction and commitment was investigated in this study with a view to finding out if both their job satisfaction and commitment have suffered, and to find out if there was a relationship between job satisfaction and commitment among these College of Education teachers. Due consideration was also given in the study to the possible effects of demographic variables on attitudes to their job. To carry out a study of job satisfaction and commitment among the College of Education teachers and to explore the relationship between them, research instruments were used for measuring the levels of job satisfaction and commitment among them. A sample of 200 Colleges of Education teachers, comprising 15 Professors, 9 Principal Lecturers, 70 Senior Lecturer and 106 Lecturers was used for the study. Five major hypothesis were tested with regard to the relationship between job satisfaction and commitment among the teachers. The Pearson correlation, the F-ratio, and regression analysis were used for data analysis and hypothesis testing. The result of this investigation suggests that, perhaps the best way to secure the commitment of teachers is to ensure their job satisfaction. Future investigations will further enrich our knowledge about these very important themes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=job%20satisfaction" title="job satisfaction">job satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=commitment" title=" commitment"> commitment</a>, <a href="https://publications.waset.org/abstracts/search?q=academic%20staff" title=" academic staff"> academic staff</a>, <a href="https://publications.waset.org/abstracts/search?q=college%20of%20education" title=" college of education"> college of education</a> </p> <a href="https://publications.waset.org/abstracts/22935/job-satisfaction-and-commitment-among-academic-staff-of-selected-colleges-of-education-in-kano-and-kaduna-states-of-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22935.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">552</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">475</span> A Queer Approach to the National Irish Identity during 'The Troubles' in Belfast in Paul Mcveigh's 'The Good Son'</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eduardo%20Garcia%20Agustin">Eduardo Garcia Agustin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper focuses on how Mickey – the 10-year-old main character and narrator in Paul McVeigh’s novel The Good Son (2015) – becomes aware of his own queerness and its implications in a conflicting place and time such as Belfast during ‘The Troubles’ in the 1980s. Queer theory allows a comparative reading of identity issues such as national and gender discourses. As opposed to some other excluding social constructs that classify identities in an Us-Others binomial, queer has become a sort of umbrella term where there is room for more identities other than LGTBQ. Therefore, it offers some relevant tools to read this highly awarded novel by focusing on the intersectional construction of Mickey’s identity in progress within the social and familiar realms. The aim of this paper is to offer a queer reading of the The Good Son, which was awarded with the Polari First Book Prize in 2016, by showing the key role of Mickey’s conflictive realization of his own queerness in the polarized society of Northern Ireland in the 1980s, where there is no shade of grey. Within such a polarized context, Mickey’s perception of his own internal and external identity conflicts he is exposed to will show how necessary a certain touch of pink is as a potential escape to those conflicts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conflict" title="conflict">conflict</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20identity" title=" national identity"> national identity</a>, <a href="https://publications.waset.org/abstracts/search?q=Northern%20Ireland" title=" Northern Ireland"> Northern Ireland</a>, <a href="https://publications.waset.org/abstracts/search?q=queer%20identity" title=" queer identity"> queer identity</a> </p> <a href="https://publications.waset.org/abstracts/72763/a-queer-approach-to-the-national-irish-identity-during-the-troubles-in-belfast-in-paul-mcveighs-the-good-son" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72763.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">533</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">474</span> IT Perspective of Service-Oriented e-Government Enterprise </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anu%20Paul">Anu Paul</a>, <a href="https://publications.waset.org/abstracts/search?q=Varghese%20Paul"> Varghese Paul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The focal aspire of e-Government (eGovt) is to offer citizen-centered service delivery. Accordingly, the citizenry consumes services from multiple government agencies through national portal. Thus, eGovt is an enterprise with the primary business motive of transparent, efficient and effective public services to its citizenry and its logical structure is the eGovernment Enterprise Architecture (eGEA). Since eGovt is IT oriented multifaceted service-centric system, EA doesn’t do much on an automated enterprise other than the business artifacts. Service-Oriented Architecture (SOA) manifestation led some governments to pertain this in their eGovts, but it limits the source of business artifacts. The concurrent use of EA and SOA in eGovt executes interoperability and integration and leads to Service-Oriented e-Government Enterprise (SOeGE). Consequently, agile eGovt system becomes a reality. As an IT perspective eGovt comprises of centralized public service artifacts with the existing application logics belong to various departments at central, state and local level. The eGovt is renovating to SOeGE by apply the Service-Orientation (SO) principles in the entire system. This paper explores IT perspective of SOeGE in India which encompasses the public service models and illustrated with a case study the Passport service of India. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=enterprise%20architecture" title="enterprise architecture">enterprise architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=service-oriented%20e-Government%20enterprise" title=" service-oriented e-Government enterprise"> service-oriented e-Government enterprise</a>, <a href="https://publications.waset.org/abstracts/search?q=service%20interface%20layer" title=" service interface layer"> service interface layer</a>, <a href="https://publications.waset.org/abstracts/search?q=service%20model" title=" service model"> service model</a> </p> <a href="https://publications.waset.org/abstracts/21308/it-perspective-of-service-oriented-e-government-enterprise" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21308.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">521</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">473</span> Scheduling of Cross-Docking Center: An Auction-Based Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eldho%20Paul">Eldho Paul</a>, <a href="https://publications.waset.org/abstracts/search?q=Brijesh%20Paul"> Brijesh Paul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work proposes an auction mechanism based solution methodology for the optimum scheduling of trucks in a cross-docking centre. The cross-docking centre is an important element of lean supply chain. It reduces the amount of storage and transportation costs in the distribution system compared to an ordinary warehouse. Better scheduling of trucks in a cross-docking center is the best way to reduce storage and transportation costs. Auction mechanism is commonly used for allocation of limited resources in different real-life applications. Here, we try to schedule inbound trucks by integrating auction mechanism with the functioning of a cross-docking centre. A mathematical model is developed for the optimal scheduling of inbound trucks based on the auction methodology. The determination of exact solution for problems involving large number of trucks was found to be computationally difficult, and hence a genetic algorithm based heuristic methodology is proposed in this work. A comparative study of exact and heuristic solutions is done using five classes of data sets. It is observed from the study that the auction-based mechanism is capable of providing good solutions to scheduling problem in cross-docking centres. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=auction%20mechanism" title="auction mechanism">auction mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=cross-docking%20centre" title=" cross-docking centre"> cross-docking centre</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=scheduling%20of%20trucks" title=" scheduling of trucks"> scheduling of trucks</a> </p> <a href="https://publications.waset.org/abstracts/62720/scheduling-of-cross-docking-center-an-auction-based-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62720.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">412</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">472</span> Measurement of the Dynamic Modulus of Elasticity of Cylindrical Concrete Specimens Used for the Cyclic Indirect Tensile Test</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paul%20G.%20Bolz">Paul G.

In order to ensure the suitability of construction materials for resisting these cyclic stresses, different test methods are used for the systematic fatiguing of specimens, like the cyclic indirect tensile test. A procedure is presented that allows the estimation of the degradation of cylindrical concrete specimens during the cyclic indirect tensile test by measuring the dynamic modulus of elasticity in different states of the specimens’ fatigue process. Two methods are used in addition to the cyclic indirect tensile test in order to examine the dynamic modulus of elasticity of cylindrical concrete specimens. One of the methods is based on the analysis of eigenfrequencies, whilst the other one uses ultrasonic pulse measurements to estimate the material properties. A comparison between the dynamic moduli obtained using the three methods that operate in different frequency ranges shows good agreement. The concrete specimens’ fatigue process can therefore be monitored effectively and reliably. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete" title="concrete">concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20indirect%20tensile%20test" title=" cyclic indirect tensile test"> cyclic indirect tensile test</a>, <a href="https://publications.waset.org/abstracts/search?q=degradation" title=" degradation"> degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20modulus%20of%20elasticity" title=" dynamic modulus of elasticity"> dynamic modulus of elasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=eigenfrequency" title=" eigenfrequency"> eigenfrequency</a>, <a href="https://publications.waset.org/abstracts/search?q=fatigue" title=" fatigue"> fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20frequency" title=" natural frequency"> natural frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonic" title=" ultrasonic"> ultrasonic</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%E2%80%99s%20modulus" title=" Young’s modulus"> Young’s modulus</a> </p> <a href="https://publications.waset.org/abstracts/133563/measurement-of-the-dynamic-modulus-of-elasticity-of-cylindrical-concrete-specimens-used-for-the-cyclic-indirect-tensile-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133563.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">174</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">471</span> Gradations in Concentration of Heavy and Mineral Elements with Distance and Depth of Soil in the Vicinity of Auto Mechanic Workshops in Sabon Gari, Kaduna State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20D.%20Paul">E.

At site 1, concentrations of lead, chromium, iron, and zinc were generally found to be above the World Health Organization limits, while those of Nickel and Cadmium fell within the limits. Iron had the highest concentration with a range of 176.274 ppm to 489.127 ppm at depths of 5 cm to 15 cm and a distance range of 5 m to 15 m, while the concentration of cadmium was least with a range of 0.001 ppm to 0.008 ppm at similar depth and distance ranges. In addition, there was more of calcium (11.521 ppm to 121.709 ppm), in all the samples, than magnesium (11.293 ppm to 21.635 ppm). Similar results were obtained for site II. The concentrations of all the metals analyzed showed a downward gradient with an increase in depth and distance from both workshop sites except for iron and zinc at site 2. The immediate and remote implications of these findings on the biota are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AAS" title="AAS">AAS</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanic%20workshops" title=" mechanic workshops"> mechanic workshops</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil"> soil</a>, <a href="https://publications.waset.org/abstracts/search?q=variation" title=" variation"> variation</a> </p> <a href="https://publications.waset.org/abstracts/23160/gradations-in-concentration-of-heavy-and-mineral-elements-with-distance-and-depth-of-soil-in-the-vicinity-of-auto-mechanic-workshops-in-sabon-gari-kaduna-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23160.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">495</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">470</span> Horn Snail (Telescopium Telescopium) Shells Waste as an Alternative for Ceramic Tile Manufacturing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patricia%20N.%20Baguio">Patricia N.

Fifty five rats were used for this study, they were divided into eleven groups of five rats each (one control group and ten test groups), the test groups were fed raw, boiled, roasted, fermented, and soaked diets at 10 % and 40% concentrations. The study lasted for thirty five days. The diets led to significant decrease (p < 0.05) in plasma cholesterol and triacylglycerol of rats fed 10% and 40% concentrations of the diets, and a significant increase (p < 0.05) in high density lipoprotein (HDL) levels at 40% concentrations of the test diets. The diets also produced decrease in low density lipoprotein (LDL), very low density lipoprotein (VLDL), cardiac risk ratio (CRR), atherogenic index of plasma (AIP) and atherogenic coefficient (AC) at 40% concentrations except the soaked group that showed slight elevation of LDL, CRR, AC and AIP at 40% concentration. Artocarpus heterophyllus seeds could be beneficial to health because of its ability to increase plasma HDL and reduce plasma LDL, VLDL, cholesterol, triglycerides and atherogenic indices at higher diet concentration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artocarpus%20heterophyllus" title="artocarpus heterophyllus">artocarpus heterophyllus</a>, <a href="https://publications.waset.org/abstracts/search?q=atherogenic%20indices" title=" atherogenic indices"> atherogenic indices</a>, <a href="https://publications.waset.org/abstracts/search?q=concentrations" title=" concentrations"> concentrations</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid%20profile" title=" lipid profile"> lipid profile</a> </p> <a href="https://publications.waset.org/abstracts/34417/plasma-lipid-profiles-and-atherogenic-indices-of-rats-fed-raw-and-processed-jack-fruit-artocarpus-heterophyllus-seeds-diets-at-different-concentrations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34417.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">302</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">467</span> Repair Workshop Queue System Modification Using Priority Scheme</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20Okonkwo%20Ugochukwu">C.

Okafor Christian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a modification on repair workshop queuing system using multi priority scheme was carried out. Chi square goodness of fit test was used to determine the random distribution of the inter arrival time and service time of crankshafts that come for maintenance in the workshop. The chi square values obtained for all the prioritized classes show that the distribution conforms to Poisson distribution. The mean waiting time in queue results of non-preemptive priority for 1st, 2nd and 3rd classes show 0.066, 0.09, and 0.224 day respectively, while preemptive priority show 0.007, 0.036 and 0.258 day. However, when non priority is used, which obviously has no class distinction it amounts to 0.17 days. From the results, one can observe that the preemptive priority system provides a very dramatic improvement over the non preemptive priority as it concerns arrivals that are of higher priority. However, the improvement has a detrimental effect on the low priority class. The trend of the results is similar to the mean waiting time in the system as a result of addition of the actual service time. Even though the mean waiting time for the queue and that of the system for no priority takes the least time when compared with the least priority, urgent and semi-urgent jobs will terribly suffer which will most likely result in reneging or balking of many urgent jobs. Hence, the adoption of priority scheme in this type of scenario will result in huge profit to the Company and more customer satisfaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=queue" title="queue">queue</a>, <a href="https://publications.waset.org/abstracts/search?q=priority%20class" title=" priority class"> priority class</a>, <a href="https://publications.waset.org/abstracts/search?q=preemptive" title=" preemptive"> preemptive</a>, <a href="https://publications.waset.org/abstracts/search?q=non-preemptive" title=" non-preemptive"> non-preemptive</a>, <a href="https://publications.waset.org/abstracts/search?q=mean%20waiting%20time" title=" mean waiting time"> mean waiting time</a> </p> <a href="https://publications.waset.org/abstracts/69985/repair-workshop-queue-system-modification-using-priority-scheme" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69985.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">396</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">466</span> Technoscience in the Information Society</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20P.%20Moiseeva">A.

Cases of poor antibody response to hepatitis B vaccination abound. Immunosuppression, especially from glucocorticoids, is often cited as a cause of poor antibody response and there are documented evidences of irrational administration of glucocorticoids to children and adults. The study was, therefore, designed to find out if administration of glucocorticoids affects immune response to vaccination against hepatitis B in mice. Methods: Mice of both sexes were randomly divided into 2 groups. Daily intramuscular methylprednisolone injections, (15 mg kg-1), were given to the test group while sterile deionized water (0.1ml) was given to control mice for 30 days. On day 6 all mice were given 2 μg (0.1ml) hepatitis B vaccine and a booster dose on day 27. On day 34, blood samples were collected and analyzed for anti-HBs titres using enzyme-linked immunosorbent assay (ELISA). Statistical analysis was done using Graph Pad Prism 5.0 and the results taken as statistically significant at p value < 0.05. Results: There were positive serum anti-HBs responses in all mice groups but the differences in titres were not statistically significant. Conclusions: At the dosages and length of exposure used in this study, methylprednisolone injection did not significantly inhibit anti-HBs response in mice following immunization against hepatitis B virus. By extrapolation, methylprednisolone, when used in the usual clinical doses and duration of therapy, is not likely to inhibit immune response to hepatitis B vaccinations in man. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-HBs" title="anti-HBs">anti-HBs</a>, <a href="https://publications.waset.org/abstracts/search?q=hepatitis%20B%20vaccine" title=" hepatitis B vaccine"> hepatitis B vaccine</a>, <a href="https://publications.waset.org/abstracts/search?q=immune%20response" title=" immune response"> immune response</a>, <a href="https://publications.waset.org/abstracts/search?q=methylprednisolone" title=" methylprednisolone"> methylprednisolone</a>, <a href="https://publications.waset.org/abstracts/search?q=mice" title=" mice"> mice</a> </p> <a href="https://publications.waset.org/abstracts/28711/methylprednisolone-injection-did-not-inhibit-anti-hbs-response-following-hepatitis-b-vaccination-in-mice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28711.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">323</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">463</span> Freshwater Lens Observation: Case Study of Laura Island, Majuro Atoll, Republic of the Marshall Islands</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kazuhisa%20Koda">Kazuhisa Koda</a>, <a href="https://publications.waset.org/abstracts/search?q=Tsutomu%20Kobayashi"> Tsutomu Kobayashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Rebecca%20Lorennji"> Rebecca Lorennji</a>, <a href="https://publications.waset.org/abstracts/search?q=Alington%20Robert"> Alington Robert</a>, <a href="https://publications.waset.org/abstracts/search?q=Halston%20DeBrum"> Halston DeBrum</a>, <a href="https://publications.waset.org/abstracts/search?q=Julious%20Lucky"> Julious Lucky</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Paul"> Paul Paul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Atolls are low-lying small islands with highly permeable ground that does not allow rivers and lakes to develop. As the water resources on these atolls basically rely on precipitation, groundwater becomes a very important water resource during droughts. Freshwater lenses develop as groundwater on relatively large atoll islands and play a key role in the stable water supply. Atoll islands in the Pacific Ocean sometimes suffer from drought due to El Nino. The global warming effects are noticeable, particularly on atoll islands. The Republic of the Marshall Islands in Oceania is burdened with the problems common to atoll islands. About half of its population lives in the capital, Majuro, and securing water resources for these people is a crucial issue. There is a freshwater lens on the largest, Laura Island, which serves as a water source for the downtown area. A serious drought that occurred in 1998 resulted in excessive water intake from the freshwater lens on Laura Island causing up-coning. Up-coning mixes saltwater into groundwater pumped from water-intake wells. Because up-coning makes the freshwater lens unusable, there was a need to investigate the freshwater lens on Laura Island. In this study, we observed the electrical conductivities of the groundwater at different depths in existing monitoring wells to determine the total storage volume of the freshwater lens on Laura Island from 2010 to 2013. Our results indicated that most of the groundwater that seeped into the freshwater lens had flowed out into the sea. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atoll%20islands" title="Atoll islands">Atoll islands</a>, <a href="https://publications.waset.org/abstracts/search?q=drought" title=" drought"> drought</a>, <a href="https://publications.waset.org/abstracts/search?q=El-Nino" title=" El-Nino"> El-Nino</a>, <a href="https://publications.waset.org/abstracts/search?q=freshwater%20lens" title=" freshwater lens"> freshwater lens</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater%20observation" title=" groundwater observation"> groundwater observation</a> </p> <a href="https://publications.waset.org/abstracts/56405/freshwater-lens-observation-case-study-of-laura-island-majuro-atoll-republic-of-the-marshall-islands" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56405.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">323</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">462</span> Factors Affecting Long-Term and Permanent Contraceptive Uptake among Immediate Post-Partum Mothers at Saint Paul’s Hospital Millennium Medical College, Addis Ababa, Ethiopia: A Cross-Sectional Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lemi%20Tolu">Lemi Tolu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Postpartum family planning (PPFP) focuses on the prevention of unintended and closely spaced pregnancies through the first 12 months following childbirth. Objective: This study assesses the barriers to uptake of long-term and permanent family planning methods among immediate post-partum mothers at Saint Paul’s Hospital Millennium Medical College in Addis Ababa, Ethiopia. Methodology: An institution-based cross-sectional study was conducted from January 1 to June 30, 2017. The six months of study were used as strata, and systematic sampling used to select participants in each month. Post-partum mothers were interviewed using pretested structured questionnaires. Data entry and analysis were done using SPSS version 17. Bivariate and multivariable logistic regressions were fitted to identify determinants of post-partum family planning uptake. An OR with 95% CIs was calculated, and p values set at 005 were used to determine the statistical significance of associations. Results: Four hundred and twenty-two post-partum women were interviewed. Two hundred sixty-eight (63%) women received counselling on family planning, and 241 (66.8 %) got information about contraception. One hundred and fifty-two (45%) of the women accepted long-term and permanent contraception on their immediate postpartum period before discharge. Contraceptive counselling (OR = 2.13, 95% CI 1.004-3.331), getting information from the health facility (OR = 15.15, 95% CI 1.848-19.242), and partner support (OR = 1.367, 95% CI 1.175-2.771) were significantly associated with long-term and permanent contraception uptake. Conclusion: Postpartum counselling on family planning and provision of contraception information improve immediate postpartum FP acceptance, and, hence postpartum programs need to strengthen such services. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contraception" title="contraception">contraception</a>, <a href="https://publications.waset.org/abstracts/search?q=immediate%20postpartum" title=" immediate postpartum"> immediate postpartum</a>, <a href="https://publications.waset.org/abstracts/search?q=long-term%20family%20planning" title=" long-term family planning"> long-term family planning</a>, <a href="https://publications.waset.org/abstracts/search?q=post-partum%20family%20planning" title=" post-partum family planning"> post-partum family planning</a> </p> <a href="https://publications.waset.org/abstracts/117269/factors-affecting-long-term-and-permanent-contraceptive-uptake-among-immediate-post-partum-mothers-at-saint-pauls-hospital-millennium-medical-college-addis-ababa-ethiopia-a-cross-sectional-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117269.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">461</span> Pediatrics HIV and Asymptomatic Malaria Parasitemia (AMP) Co-Infection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20Segun%20Adeniyi">David Segun Adeniyi</a>, <a href="https://publications.waset.org/abstracts/search?q=Tongvwam%20P.%20J."> Tongvwam P.

In this study, we sought to establish the relationship between AMP and sustained plasma HIV viremia among a population of pediatric clients on Antiretroviral Therapy (ART). We also seek to determine the prevalence of AMP among the study population. Methods: 180 pediatrics clients on ART at four (4) Comprehensive Hospitals in Jos, Nigeria, participated in this study between the months of October to December 2022. The mean age of the study participants was 13 years. Venous blood was drawn from the participants after consent was sought, and ethical approval was obtained from the Plateau State Specialist Hospital (PSSH) Research and Ethics Committee. All samples were screened for AMP using the CareStart® HRP2 Malaria kit. The Absolute and % CD4 values of the clients were obtained using the BD Presto® CD4 Analyzer. The separated plasma samples were assayed for HIV viral load using the Roche Cobas C4800® system. Obtained data were analyzed using simple descriptive statistics. Results: From the 180 participants in this study, 12.8% (23) have AMP. 90.6% (163) were virally suppressed (<1000 copies/ml), while 9.4% (17) were virally unsuppressed (>1000 copies/ml). 11.7% (19/163) of the virally suppressed population have AMP, with mean absolute and % CD4 values of 648 and 31%, respectively. The virally suppressed population without AMP has mean absolute and % CD4 values of 719 and 32%, respectively. 24% (4/17) of the virally unsuppressed population have AMP, with mean absolute and % CD4 values of 514 and 26%, respectively. The virally unsuppressed population without AMP has mean absolute and % CD4 values of 292 and 16%, respectively. Conclusion: Our study shows that there is a high prevalence of AMP among the study populations (11.7% and 24%, respectively). The high prevalence of AMP among the virally unsuppressed with mean absolute and % CD4 values of 514 and 26% alludes to the fact that malaria co-infection with HIV fosters a dysregulated immune complex response which favors an increased HIV plasma viremia. We thus recommend the routine use of Malaria IPT in pediatric HIV clients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pediatrics" title="pediatrics">pediatrics</a>, <a href="https://publications.waset.org/abstracts/search?q=HIV" title=" HIV"> HIV</a>, <a href="https://publications.waset.org/abstracts/search?q=Malaria" title=" Malaria"> Malaria</a>, <a href="https://publications.waset.org/abstracts/search?q=viral%20suppression" title=" viral suppression"> viral suppression</a> </p> <a href="https://publications.waset.org/abstracts/161882/pediatrics-hiv-and-asymptomatic-malaria-parasitemia-amp-co-infection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161882.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">83</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">460</span> Performance Evaluation and Kinetics of Artocarpus heterophyllus Seed for the Purification of Paint Industrial Wastewater by Coagulation-Flocculation Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ifeoma%20Maryjane%20Iloamaeke">Ifeoma Maryjane Iloamaeke</a>, <a href="https://publications.waset.org/abstracts/search?q=Kelvin%20Obazie"> Kelvin Obazie</a>, <a href="https://publications.waset.org/abstracts/search?q=Mmesoma%20Offornze"> Mmesoma Offornze</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiamaka%20Marysilvia%20Ifeaghalu"> Chiamaka Marysilvia Ifeaghalu</a>, <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Aduaka"> Cecilia Aduaka</a>, <a href="https://publications.waset.org/abstracts/search?q=Ugomma%20Chibuzo%20Onyeije"> Ugomma Chibuzo Onyeije</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudine%20Ifunanaya%20Ogu"> Claudine Ifunanaya Ogu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ngozi%20Anastesia%20Okonkwo"> Ngozi Anastesia Okonkwo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work investigated the effects of pH, settling time, and coagulant dosages on the removal of color, turbidity, and heavy metals from paint industrial wastewater using the seed of Artocarpus heterophyllus (AH) by the coagulation-flocculation process. The paint effluent was physicochemically characterized, while AH coagulant was instrumentally characterized by Scanning Electron Microscope (SEM), Fourier Transform Infrared (FTIR), and X-ray diffraction (XRD). A Jar test experiment was used for the coagulation-flocculation process. The result showed that paint effluent was polluted with color, turbidity (36000 NTU), mercury (1.392 mg/L), lead (0.252 mg/L), arsenic (1.236 mg/L), TSS (63.40mg/L), and COD (121.70 mg/L). The maximum color removal efficiency was 94.33% at the dosage of 0.2 g/L, pH 2 at a constant time of 50 mins, and 74.67% at constant pH 2, coagulant dosage of 0.2 g/L and 50 mins. The highest turbidity removal efficiency was 99.94% at 0.2 g/L and 50 mins at constant pH 2 and 96.66% at pH 2 and 0.2 g/L at constant time of 50 mins. The mercury removal efficiency of 99.29% was achieved at the optimal condition of 0.8 g/L coagulant dosage, pH 8, and constant time of 50 mins and 99.57% at coagulant dosage of 0.8 g/L, time of 50 mins constant pH 8. The highest lead removal efficiency was 99.76% at a coagulant dosage of 10 g/L, time of 40 mins at constant pH 10, and 96.53% at pH 10, coagulant dosage of 10 g/L and constant time of 40 mins. For arsenic, the removal efficiency is 75.24 % at 0.8 g/L coagulant dosage, time of 40 mins, and constant pH of 8. XRD imaging before treatment showed that Artocarpus heterophyllus coagulant was crystalline and changed to amorphous after treatment. The SEM and FTIR results of the AH coagulant and sludge suggested there were changes in the surface morphology and functional groups before and after treatment. The reaction kinetics were modeled best in the second order. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Artocarpus%20heterophyllus"
