Artificial Reproduction System is an attempt towards a new computational intelligence approach inspired by the theoretical reproduction mechanism, observed reproduction functions, principles and mechanisms. A reproductive organism is programmed by genes and can be viewed as an automaton, mapping and reducing so as to create copies of those genes in its off springs. In Artificial Reproduction System, the binding mechanism between male and female cells is studied, parameters are chosen and a network is constructed also a feedback system for self regularization is established. The model then applies Mendel’s law of inheritance, allele-allele associations and can be used to perform data analysis of imbalanced data, multivariate, multiclass and big data. In the experimental study Artificial Reproduction System is compared with other state of the art classifiers like SVM, Radial Basis Function, neural networks, K-Nearest Neighbor for some benchmark datasets and comparison results indicates a good performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-inspired%20computation" title="bio-inspired computation">bio-inspired computation</a>, <a href="https://publications.waset.org/abstracts/search?q=nature-%20inspired%20computation" title=" nature- inspired computation"> nature- inspired computation</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20computing" title=" natural computing"> natural computing</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20mining" title=" data mining"> data mining</a> </p> <a href="https://publications.waset.org/abstracts/54679/artificial-reproduction-system-and-imbalanced-dataset-a-mendelian-classification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54679.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">272</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">266</span> Analysis of Subordination: The Reproductive Sphere</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aneesa%20Shafi">Aneesa Shafi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reproduction is a complex term in a setting where it is continuously being shaped by epistemological shifts in knowledge. It denotes not just fertility, birth and childcare related practices but also the ideas that shape those practices. These ideas and practices figure into understandings of social and cultural renewal. Patriarchy continues to be a dominating force in the formation of these ideas and practices. Contemporary times are characterized by the resurgence of the whims of patriarchal politics in delineating the margins of women’s health care. This has further emboldened the struggle for reproductive rights on the global stage. The paper examines the subordination of the right to bodily autonomy of women within the ambit of their reproductive rights. Reproductive rights are recognized human rights and women’s rights. Why these rights of women face stiff opposition is established, as is the structure that creates hurdles to their enjoyment. The negotiation of this structure in the everyday life through women’s agency is also established. The reproductive sphere includes not just the process of reproduction but also social reproduction- domestic work, spheres of production and reproduction, population and birth (control) issues. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=patriarchy" title="patriarchy">patriarchy</a>, <a href="https://publications.waset.org/abstracts/search?q=women" title=" women"> women</a>, <a href="https://publications.waset.org/abstracts/search?q=reproduction" title=" reproduction"> reproduction</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a> </p> <a href="https://publications.waset.org/abstracts/81427/analysis-of-subordination-the-reproductive-sphere" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81427.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">227</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">265</span> A Feminist/Queer Global Bioethics’Perspective on Reproduction: Abortion, MAR and Surrogacy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tamara%20Roma">Tamara Roma</a>, <a href="https://publications.waset.org/abstracts/search?q=Emma%20Capulli"> Emma Capulli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pregnancy and fertility, in other words, reproduction, has become, in the last half of the century, increasingly and globally controlled, medicalized, and regulated. The reflection proposed starts from the consequences of the inscription of reproduction into the neoliberal economic paradigm. The new biotechnologies developments have raised a new patriarchal justification for State’s control of uterus bodies and a new construction of knowledge about reproductive health. Moral discussion and juridification remove reproduction and non-reproduction from their personal and intimate context and frame them under words like “duties”, “rights”, “family planning”, “demography”, and “population policy”, reinvent them as “States business” and ultimately help to re/confirm a specific construct of fertility, motherhood, and family. Moreover, the interaction between the neoliberal economy and medical biotechnologies brought about a new formulation of the connection between feminine generative potential and value production. The widespread and contemporary debates on Medically Assisted Reproduction (MAR), surrogacy and abortion suggest the need for a “feminist/queer global bioethical discourse” capable of inserting itself into the official bioethical debate characterized by the traditional dichotomy of laic bioethics/Catholic bioethics. The contribution moves from a feminist bioethics perspective on reproductive technologies to introduce a feminist/queer global bioethics point of view on reproductive health. The comparison between reproduction and non-reproduction debates is useful to analyze and demonstrate how restrictive legislations, dichotomic bioethical discussion and medical control confirm and strengthens gender injustice in reproductive life. In fact, MAR, surrogacy, and abortion restrictions stem from a shared social and legal paradigm that depends on traditional gender roles revealing how the stratification of reproduction is based on multiple discrimination along the lines of gender, race, and class. In conclusion, the perspective of feminist/queer global bioethics tries to read the concept of universal reproductive justice, introducing an original point of view on reproductive health access. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=queer%20bioethics" title="queer bioethics">queer bioethics</a>, <a href="https://publications.waset.org/abstracts/search?q=reproductive%20health" title=" reproductive health"> reproductive health</a>, <a href="https://publications.waset.org/abstracts/search?q=reproductive%20justice" title=" reproductive justice"> reproductive justice</a>, <a href="https://publications.waset.org/abstracts/search?q=reproductive%20technologies" title=" reproductive technologies"> reproductive technologies</a> </p> <a href="https://publications.waset.org/abstracts/165061/a-feministqueer-global-bioethicsperspective-on-reproduction-abortion-mar-and-surrogacy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165061.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">124</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">264</span> Contribution to the Study of Reproduction of Water Birds (Case of Marsh Bouessdra, North East Algeria)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wahiba%20Boudraa">Wahiba Boudraa</a>, <a href="https://publications.waset.org/abstracts/search?q=Khalil%20Draidi"> Khalil Draidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Badis%20Bakhouch"> Badis Bakhouch</a>, <a href="https://publications.waset.org/abstracts/search?q=Farah%20Chettibi"> Farah Chettibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Meriem%20Aberkane"> Meriem Aberkane</a>, <a href="https://publications.waset.org/abstracts/search?q=Zihad%20Bouslama"> Zihad Bouslama</a>, <a href="https://publications.waset.org/abstracts/search?q=Moussa%20Houhamdi"> Moussa Houhamdi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Gulf of Annaba, located at the extreme north eastern Algerian; our site of study is a marsh administratively it is part of the wilaya of Annaba, municipality of El-Bouni; extends on a surface from 55 hectare, the maximum depth is of less 2m. A scheme of work was adopted for an evaluation and characterization of the reproduction of the water nicheurs birds in the marsh of Boussedra. Some important parameters described by the scientific literature; According to standardized methods, variables were the object of a regular follow-up during the period of reproduction. These parameters were taken into account: the installation date of the nests, the vegetable support; blossoming of eggs, causes of the failure of the blossomings (predation or abandonment), characteristics of the nests (composition, internal diameter, external diameter, depth and heightening), measurements of the distances nest-nest nearest, Depth of water, the measurement of eggs, size of laying, size of laying. The follow-up in the marsh was carried out between March 2013 until the month of July 2014 at a rate of two outputs per weeks, one located and noted the nests to control them each week. The study on the reproduction of the water birds enables us to note that this site plays a very important part in the wintering and the reproduction of certain species important. This study opens broad prospects for study of several phenomena related to the ecology of the water birds, and the conservation of the wetlands. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Algeria" title="Algeria">Algeria</a>, <a href="https://publications.waset.org/abstracts/search?q=Boussedra" title=" Boussedra"> Boussedra</a>, <a href="https://publications.waset.org/abstracts/search?q=nests" title=" nests"> nests</a>, <a href="https://publications.waset.org/abstracts/search?q=reproduction" title=" reproduction"> reproduction</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20birds" title=" water birds"> water birds</a> </p> <a href="https://publications.waset.org/abstracts/38053/contribution-to-the-study-of-reproduction-of-water-birds-case-of-marsh-bouessdra-north-east-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38053.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">257</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">263</span> The Potency of Sandfish (Holothuria scraba) Flesh Powder to Improve Reproduction Quality of Man</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Riani">E.

This study aimed to examine the nutrition on sandfish flesh that has the potency to improve reproduction quality of men. The materials used were sandfish with weight of 200-500 g, and then analysis of proximate, analysis of amino acid, analysis of fatty acid and analysis of mineral contained in the sandfish were performed. The results showed that protein content (39.96%) was the main component of the flesh; the carbohydrate and fat were 25.43% and 4.18%, respectively. Sandfish powder contains several essential amino acids and nonessential amino acids. Nine of ten amino acids needed by human body are contained in sandfish powder, i.e. arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, tryptophan, threonine and valine; only tryptophan that are not contained in sandfish powder. Sandfish powder contains saturated fatty acid kaproat, kaprilat, kaprat, laurat, miristat, stearat, arakhidat and behenat; monosaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA). MUFA is composed of fatty acid oleat, while PUFA is composed fatty acid omega 3 (linonenat, eicosapentaenoic acid and docosahexaenoic acid) and omega 6 (linoleat and arakhidonat). The minerals contained in sandfish powder are macrominerals and microminerals. Based on the findings, the nutrition in sandfish powder has a good potency to improve reproduction of men, especially PUFA for the maturation of spermatozoa, zinc for production function and spermatogenesis, motility of spermatozoa, acromoson reaction; Mg for transformation of genetic information and motility of spermatozoa; calcium for spermatogenesis, capacity and fertilization of spermatozoa. Thus, sandfish flesh powder has the potency to improve reproduction quality of men. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sandfish%20flesh%20powder" title="sandfish flesh powder">sandfish flesh powder</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrition" title=" nutrition"> nutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=reproduction%20quality" title=" reproduction quality"> reproduction quality</a>, <a href="https://publications.waset.org/abstracts/search?q=men" title=" men"> men</a> </p> <a href="https://publications.waset.org/abstracts/11006/the-potency-of-sandfish-holothuria-scraba-flesh-powder-to-improve-reproduction-quality-of-man" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11006.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">454</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">262</span> Relationship between Reproduction Performances and Coat Characteristics of Montbeliarde Cows during Hot Season in Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sara%20Lamari">Sara Lamari</a>, <a href="https://publications.waset.org/abstracts/search?q=Toufik%20Madani"> Toufik Madani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed to explore the relationship between reproduction performances and coat characteristics of Montbéliarde cows born in Algeria or imported from Europe during the hot season in Algeria. Hair coat traits (hair coat color, Hair Weight, hair length, the number of hair per unit area, total hair diameters and hair medulla diameters) were estimated in 18 imported cattle and 49 locally born cows. These traits were measured in an area of 20cm below the dorsal line in the center of the thorax. Results showed that hair coats were significantly different between locally born and imported cows. Imported cows had whiter coats when compared to locally born cows for Montbéliarde cows. A significant effect of total hair diameter was observed on the interval from calving to conception (IC) for imported Montbéliarde cows, suggesting less incidence of heat stress on reproduction efficiency of cows with thin diameter hair coats. Montbéliarde cows with short hair coat registered significantly more number of mating per conception (2, 28±1, 93 Vs. 1,67±0,92) and IC (98,04±78,81Vs 74.53 ± 35.60 days) when compared to cows with long hairs. Hair works as a temperature regulator in association with muscles in the skin and may affect reproduction performances during hit stress season. It can be assumed that the length and a total diameter of hairs for the Montbeliarde breed appears to be related to their reproductive efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hair%20coat" title="hair coat">hair coat</a>, <a href="https://publications.waset.org/abstracts/search?q=reproduction" title=" reproduction"> reproduction</a>, <a href="https://publications.waset.org/abstracts/search?q=Montbeliarde%20cow" title=" Montbeliarde cow"> Montbeliarde cow</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20season" title=" hot season"> hot season</a> </p> <a href="https://publications.waset.org/abstracts/138643/relationship-between-reproduction-performances-and-coat-characteristics-of-montbeliarde-cows-during-hot-season-in-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138643.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">165</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">261</span> Modelling the Spread of HIV/AIDS Epidemic with Condom Campaign and Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marsudi">Marsudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Noor%20Hidayat"> Noor Hidayat</a>, <a href="https://publications.waset.org/abstracts/search?q=Ratno%20Bagus%20Edy%20Wibowo"> Ratno Bagus Edy Wibowo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper considers a deterministic model for the transmission dynamics of HIV/AIDS in which condom campaign and treatment are both important for the disease management.

We calculate the effective reproduction number using the next generation matrix method and investigate the existence and stability of the equilibrium points. A sensitivity analysis discovers parameters that have a high impact on effective reproduction number and should be targeted by intervention strategies.

Therefore, in the present study, we propose a susceptible–infected–recovered (SIR) epidemic model along with time delay, modulated incidence rate of infection, and Holling Type II nonlinear treatment rate. The present model aims to provide a strategy to control the spread of epidemics. In the mathematical study of the model, it has been shown that the model has two equilibriums which are named as disease-free equilibrium (DFE) and endemic equilibrium (EE). Further, stability analysis of the model is discussed. To prove the stability of the model at DFE, we derived basic reproduction number, denoted by (R₀). With the help of basic reproduction number (R₀), we showed that the model is locally asymptotically stable at DFE when the basic reproduction number (R₀) less than unity and unstable when the basic reproduction number (R₀) is greater than unity. Furthermore, stability analysis of the model at endemic equilibrium has also been discussed. Finally, numerical simulations have been done using MATLAB 2012b to exemplify the theoretical results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=time%20delayed%20SIR%20epidemic%20model" title="time delayed SIR epidemic model">time delayed SIR epidemic model</a>, <a href="https://publications.waset.org/abstracts/search?q=modulated%20incidence%20rate" title=" modulated incidence rate"> modulated incidence rate</a>, <a href="https://publications.waset.org/abstracts/search?q=Holling%20type%20II%20nonlinear%20treatment%20rate" title=" Holling type II nonlinear treatment rate"> Holling type II nonlinear treatment rate</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a> </p> <a href="https://publications.waset.org/abstracts/90497/dynamics-of-a-susceptible-infected-recovered-model-along-with-time-delay-modulated-incidence-and-nonlinear-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90497.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">154</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">259</span> Flow Reproduction Using Vortex Particle Methods for Wake Buffeting Analysis of Bluff Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samir%20Chawdhury">Samir Chawdhury</a>, <a href="https://publications.waset.org/abstracts/search?q=Guido%20Morgenthal"> Guido Morgenthal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper presents a novel extension of Vortex Particle Methods (VPM) where the study aims to reproduce a template simulation of complex flow field that is generated from impulsively started flow past an upstream bluff body at certain Reynolds number Re-Vibration of a structural system under upstream wake flow is often considered its governing design criteria. Therefore, the attention is given in this study especially for the reproduction of wake flow simulation. The basic methodology for the implementation of the flow reproduction requires the downstream velocity sampling from the template flow simulation; therefore, at particular distances from the upstream section the instantaneous velocity components are sampled using a series of square sampling-cells arranged vertically where each of the cell contains four velocity sampling points at its corner. Since the grid free Lagrangian VPM algorithm discretises vorticity on particle elements, the method requires transformation of the velocity components into vortex circulation, and finally the simulation of the reproduction of the template flow field by seeding these vortex circulations or particles into a free stream flow. It is noteworthy that the vortex particles have to be released into the free stream exactly at same rate of velocity sampling. Studies have been done, specifically, in terms of different sampling rates and velocity sampling positions to find their effects on flow reproduction quality. The quality assessments are mainly done, using a downstream flow monitoring profile, by comparing the characteristic wind flow profiles using several statistical turbulence measures. Additionally, the comparisons are performed using velocity time histories, snapshots of the flow fields, and the vibration of a downstream bluff section by performing wake buffeting analyses of the section under the original and reproduced wake flows. Convergence study is performed for the validation of the method. The study also describes the possibilities how to achieve flow reproductions with less computational effort. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vortex%20particle%20method" title="vortex particle method">vortex particle method</a>, <a href="https://publications.waset.org/abstracts/search?q=wake%20flow" title=" wake flow"> wake flow</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20reproduction" title=" flow reproduction"> flow reproduction</a>, <a href="https://publications.waset.org/abstracts/search?q=wake%20buffeting%20analysis" title=" wake buffeting analysis"> wake buffeting analysis</a> </p> <a href="https://publications.waset.org/abstracts/27394/flow-reproduction-using-vortex-particle-methods-for-wake-buffeting-analysis-of-bluff-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27394.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">311</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">258</span> Time Delayed Susceptible-Vaccinated-Infected-Recovered-Susceptible Epidemic Model along with Nonlinear Incidence and Nonlinear Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kanica%20Goel">Kanica Goel</a>, <a href="https://publications.waset.org/abstracts/search?q=Nilam"> Nilam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Infectious diseases are a leading cause of death worldwide and hence a great challenge for every nation. Thus, it becomes utmost essential to prevent and reduce the spread of infectious disease among humans. Mathematical models help to better understand the transmission dynamics and spread of infections. For this purpose, in the present article, we have proposed a nonlinear time-delayed SVIRS (Susceptible-Vaccinated-Infected-Recovered-Susceptible) mathematical model with nonlinear type incidence rate and nonlinear type treatment rate. Analytical study of the model shows that model exhibits two types of equilibrium points, namely, disease-free equilibrium and endemic equilibrium. Further, for the long-term behavior of the model, stability of the model is discussed with the help of basic reproduction number R₀ and we showed that disease-free equilibrium is locally asymptotically stable if the basic reproduction number R₀ is less than one and unstable if the basic reproduction number R₀ is greater than one for the time lag τ≥0. Furthermore, when basic reproduction number R₀ is one, using center manifold theory and Casillo-Chavez and Song theorem, we showed that the model undergoes transcritical bifurcation. Moreover, numerical simulations are being carried out using MATLAB 2012b to illustrate the theoretical results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20incidence%20rate" title="nonlinear incidence rate">nonlinear incidence rate</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20treatment%20rate" title=" nonlinear treatment rate"> nonlinear treatment rate</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20delayed%20SVIRS%20epidemic%20model" title=" time delayed SVIRS epidemic model"> time delayed SVIRS epidemic model</a> </p> <a href="https://publications.waset.org/abstracts/91055/time-delayed-susceptible-vaccinated-infected-recovered-susceptible-epidemic-model-along-with-nonlinear-incidence-and-nonlinear-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91055.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">149</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">257</span> The Effect of Racism in the Media to Deal With Migration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rasha%20Ali%20Dheyab">Rasha Ali Dheyab</a>, <a href="https://publications.waset.org/abstracts/search?q=Edurad%20Vlad"> Edurad Vlad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Migration is associated with other important global issues, including development, poverty, and human rights. Migrants are often the most dynamic members of society; historically, migration has supported economic development and the rise of nations and enriched cultures. It also presents significant challenges. The word ‘racism’ is not just about beliefs or statements; it also contains the ability to force those beliefs or world views as hegemonic and as a basis for the refusal of rights or equality. For this reason, racism is embedded in power relations of different types. Racism is not only an awareness of distinction and groups, but it also has extremely practical roles in maintaining: First, inequitable social power arrangements; and second, racist behavioral manifestations such as verbal rejection, avoidance, discrimination, physical attack, and elimination. The focus is on aspects of racism in the media to deal with the migration phenomenon. The reproduction and promotion of racism by certain areas of the media is not a simple and straightforward process. It is important to see how the media serves in the reproduction of racism. This article shows attitudes to migration as they have appeared in British periodicals over the last few years. One might conclude that the reproduction of racism by the media is not a simple and straightforward process. It has become obvious that the role of the media in the reproduction of racism is inextricably linked to the general characteristics of racism and white domination in society, particularly the structural and ideological structuring of that kind of group power. This highlights the press's function as a business, social, and cultural institution. The press has to be examined in connection to the institutions of the economic and political as well. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=British%20periodicals" title="British periodicals">British periodicals</a>, <a href="https://publications.waset.org/abstracts/search?q=culture%20studies" title=" culture studies"> culture studies</a>, <a href="https://publications.waset.org/abstracts/search?q=migration" title=" migration"> migration</a>, <a href="https://publications.waset.org/abstracts/search?q=racism" title=" racism"> racism</a> </p> <a href="https://publications.waset.org/abstracts/139006/the-effect-of-racism-in-the-media-to-deal-with-migration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139006.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">213</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">256</span> Stability Analysis of Modelling the Effect of Vaccination and Novel Quarantine-Adjusted Incidence on the Spread of Newcastle Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nurudeen%20O.%20Lasisi">Nurudeen O.

Considering the game of life rules, Wolfram's works about life-like structures and John von Neumann's self-replication, self-maintenance, self-reproduction problems, we developed 2-states and 3-states hexagonal growing algorithms that reach large populations through random initial states. Unlike the game of life, we used six neighbourhoods cellular automata instead of eight or four neighbourhoods. First simulations explained that whether we are able to obtain sort of oscillators, blinkers, and gliders. Inspired by Wolfram's 1D cellular automata complexity and life-like structures, we simulated 2D synchronous, discrete, deterministic cellular automata to reach life-like forms with 2-states cells. The life-like formations and the oscillators have been explained how they contribute to initiating self-maintenance together with self-reproduction and self-replication. After comparing simulation results, we decided to develop the algorithm for another step. Appending a new state to the same algorithm, which we used for reaching life-like structures, led us to experiment new branching and fractal forms. All these studies tried to demonstrate that complex life forms might come from uncomplicated rules. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hexagonal%20cellular%20automata" title="hexagonal cellular automata">hexagonal cellular automata</a>, <a href="https://publications.waset.org/abstracts/search?q=self-replication" title=" self-replication"> self-replication</a>, <a href="https://publications.waset.org/abstracts/search?q=self-reproduction" title=" self-reproduction"> self-reproduction</a>, <a href="https://publications.waset.org/abstracts/search?q=self-%20maintenance" title=" self- maintenance"> self- maintenance</a> </p> <a href="https://publications.waset.org/abstracts/99380/2d-hexagonal-cellular-automata-the-complexity-of-forms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99380.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">152</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">254</span> Stability Analysis of Endemic State of Modelling the Effect of Vaccination and Novel Quarantine-Adjusted Incidence on the Spread of Newcastle Disease Virus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nurudeen%20Oluwasola%20Lasisi">Nurudeen Oluwasola Lasisi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdulkareem%20Afolabi%20Ibrahim"> Abdulkareem Afolabi Ibrahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Newcastle disease is an infection of domestic poultry and other bird species with virulent Newcastle disease virus (NDV).

As of 2019, it is considered a critically endangered species. Due to its ecological importance and its endangered status, several initiatives have been developed for its salvation and recovery. This research is an effort to understand and control its reproduction under captivity. As a limited number of Pinna nobilis individuals could be used for experimentation, the possibility of using the Pinna rudis as a model animal was explored. The molecular mechanism that regulates the reproduction of both species is unknown; consequently, transcriptomic analysis was performed to identify neuropeptides that are expressed in the key regulatory tissues of the visceral ganglia and gonads of both species. Neuropeptides form an important group of signaling peptides that regulate reproductive, behavioral and physiological functions in molluscs. In total, 17 neuropeptide precursors were identified in P. nobilis and 14 in P. rudis transcriptomes; 14 of them were identical in both species. This affinity verified the genetic similarity of these species at the reproduction level. APGWamide, buccalin, ELH and GnRH were tested in P. rudis and demonstrated their capacity to advance gonadal maturation and trigger spawning while spawning was recorded in P. nobilis after the usage of APGWamide and buccalin. The neuropeptides were administered using intramuscular injection and cholesterol implants following relative literature as well as a new method was developed for external administration without the use of anesthesia using a mathematical model. The know-how of this research will not only lead to the survival of the species but also will narrow the horizons of broodstock conditioning of other similar species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neuropeptides" title="neuropeptides">neuropeptides</a>, <a href="https://publications.waset.org/abstracts/search?q=Pinna%20nobilis" title=" Pinna nobilis"> Pinna nobilis</a>, <a href="https://publications.waset.org/abstracts/search?q=reproduction" title=" reproduction"> reproduction</a>, <a href="https://publications.waset.org/abstracts/search?q=transcriptomics" title=" transcriptomics"> transcriptomics</a> </p> <a href="https://publications.waset.org/abstracts/169695/gonadal-maturation-in-pen-shells-pinna-rudis-and-pinna-nobilis-stimulated-by-reproductive-neuropeptides" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169695.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">103</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">252</span> Numerical and Sensitivity Analysis of Modeling the Newcastle Disease Dynamics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nurudeen%20Oluwasola%20Lasisi">Nurudeen Oluwasola Lasisi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Newcastle disease is a highly contagious disease of birds caused by a para-myxo virus. In this paper, we presented Novel quarantine-adjusted incident and linear incident of Newcastle disease model equations. We considered the dynamics of transmission and control of Newcastle disease. The existence and uniqueness of the solutions were obtained. The existence of disease-free points was shown, and the model threshold parameter was examined using the next-generation operator method. The sensitivity analysis was carried out in order to identify the most sensitive parameters of the disease transmission. This revealed that as parameters β,ω, and ᴧ increase while keeping other parameters constant, the effective reproduction number R_ev increases. This implies that the parameters increase the endemicity of the infection of individuals. More so, when the parameters μ,ε,γ,δ_1, and α increase, while keeping other parameters constant, the effective reproduction number R_ev decreases. This implies the parameters decrease the endemicity of the infection as they have negative indices. Analytical results were numerically verified by the Differential Transformation Method (DTM) and quantitative views of the model equations were showcased. We established that as contact rate (β) increases, the effective reproduction number R_ev increases, as the effectiveness of drug usage increases, the R_ev decreases and as the quarantined individual decreases, the R_ev decreases. The results of the simulations showed that the infected individual increases when the susceptible person approaches zero, also the vaccination individual increases when the infected individual decreases and simultaneously increases the recovery individual. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=disease-free%20equilibrium" title="disease-free equilibrium">disease-free equilibrium</a>, <a href="https://publications.waset.org/abstracts/search?q=effective%20reproduction%20number" title=" effective reproduction number"> effective reproduction number</a>, <a href="https://publications.waset.org/abstracts/search?q=endemicity" title=" endemicity"> endemicity</a>, <a href="https://publications.waset.org/abstracts/search?q=Newcastle%20disease%20model" title=" Newcastle disease model"> Newcastle disease model</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical" title=" numerical"> numerical</a>, <a href="https://publications.waset.org/abstracts/search?q=Sensitivity%20analysis" title=" Sensitivity analysis"> Sensitivity analysis</a> </p> <a href="https://publications.waset.org/abstracts/183447/numerical-and-sensitivity-analysis-of-modeling-the-newcastle-disease-dynamics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183447.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">45</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">251</span> Sublethal Effect of Tebufenozide, an Ecdysteroid Agonist, on the Reproduction of German Cockroach (Blattodea: Blattellidae)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samira%20Kilani-Morakchi">Samira Kilani-Morakchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Amina%20Badi"> Amina Badi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Aribi"> Nadia Aribi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> German cockroach, Blattella germanica, is known to be an important pest due to its high reproductive potential and its ability to build up large infectious populations. The infestations were generally controlled by neurotoxic insecticides including organophosphates (OP), carbamate and pyrethroids. An alternative cockroach’s control approach is the use insect growth regulators (IGRs). The relative fewer effects of these chemicals on non-target insects and animals, and their favourable environmental fate, make them attractive insecticides for inclusion in integrated pest management programmes. The juvenoids and chitin synthesis inhibitors are two classes of IGRs that have received the most attention for useful chemicals to manage German cockroaches while ecdysone agonists were mostly used to control Lepidopteran species. In the present study, the sublethal effects of the non-sreroidal ecdysone agonist tebufenozide were evaluated topically on adults of the B. germanica. The effects on reproduction were observed in adults females of cockroaches that survived exposure to LD25 (146 µg/g of insect) of tebufenozide. Dissection of treated females showed a clear reduction in both the number of oocytes per paired ovaries and the size of basal oocytes, as compared to controls. In addition, tebufenozide significantly reduced the mating success of pairs and altered the fertility as shown through the reduction of ootheca development and total absence of viable nymph. Tebufenozide disrupted the German cockroach reproduction by interfering with homeostasis of the insect hormones. In conclusion, the overall results suggested that tebufenozide can be used as a biorational insecticide for controlling cockroaches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20germanica" title="B. germanica">B. germanica</a>, <a href="https://publications.waset.org/abstracts/search?q=ecdysteroid%20agonist" title=" ecdysteroid agonist"> ecdysteroid agonist</a>, <a href="https://publications.waset.org/abstracts/search?q=tebufenozide" title=" tebufenozide"> tebufenozide</a>, <a href="https://publications.waset.org/abstracts/search?q=reproduction" title=" reproduction"> reproduction</a> </p> <a href="https://publications.waset.org/abstracts/31258/sublethal-effect-of-tebufenozide-an-ecdysteroid-agonist-on-the-reproduction-of-german-cockroach-blattodea-blattellidae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31258.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">296</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">250</span> Advantages of Sexual Reproduction in Aspergillus nidulans</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adel%20Omar%20Ashour">Adel Omar Ashour</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20S.%20Dyer"> Paul S. Dyer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aspergillus nidulans can reproduce by asexual or sexual means, producing green conidiospores or red-purple ascospores respectively. The latter one is produced in dark-purple globose ‘cleistothecia’ which are surrounded by Hülle cells. The species has a homothallic (self fertile) sexual breeding system. Given the extra metabolic costs associated with sexual compared to asexual reproduction it would be predicted that ascospore production would confer evolutionary benefits. However, due to the homothallic breeding system there is very rarely any increased genetic variation in ascospore offspring and traditionally conidia and ascospores are considered to be equally environmental resistant. We therefore examined in detail whether conidia and ascospores might exhibit as yet undetected differences in spore viability when subjected to certain environmental stressors. Spores from two strains of A. nidulans (comprising wild-type and KU mutants) were exposed to various levels of temperature (50-70°C for 30 min) and UV (350 nm for 10-60 min) stress. Results of experiments will be presented, including comparison of ‘D’ (decimal point reduction) values of conidia versus ascospores of A. nidulans. We detected that under certain exposure levels ascospores have significantly increased resistance compared to conidia. The increased environmental resistance of ascospores might be a key factor explaining the persistence of sexuality in this homothallic species, and reasons for differential survival are suggested. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aspergillus%20nidulans" title="Aspergillus nidulans">Aspergillus nidulans</a>, <a href="https://publications.waset.org/abstracts/search?q=asexual%20reproduction" title=" asexual reproduction"> asexual reproduction</a>, <a href="https://publications.waset.org/abstracts/search?q=conidia" title=" conidia"> conidia</a>, <a href="https://publications.waset.org/abstracts/search?q=ascospores" title=" ascospores"> ascospores</a>, <a href="https://publications.waset.org/abstracts/search?q=cleistothecia" title=" cleistothecia"> cleistothecia</a>, <a href="https://publications.waset.org/abstracts/search?q=d-value" title=" d-value"> d-value</a> </p> <a href="https://publications.waset.org/abstracts/12806/advantages-of-sexual-reproduction-in-aspergillus-nidulans" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12806.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">362</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">249</span> The Perspective of Waria Transgenders in Singaraja on Their Reproduction Health</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Made%20Kurnia%20Widiastuti%20Giri">Made Kurnia Widiastuti Giri</a>, <a href="https://publications.waset.org/abstracts/search?q=Nyoman%20Kanca"> Nyoman Kanca</a>, <a href="https://publications.waset.org/abstracts/search?q=Arie%20Swastini"> Arie Swastini</a>, <a href="https://publications.waset.org/abstracts/search?q=Bambang%20Purwanto"> Bambang Purwanto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim: Waria transgenders are a phenomenon whose existence is undeniable. The sexual behaviours of waria transgenders belong to the groups of high-risk STDs infections, especially HIV/AIDS. The present study was aimed at finding out the general idea of the existence of waria transgenders in Singaraja, their sexual transactions, their sexual behaviours, and at exploring the factors affecting their sexual behaviours along with their participation in regular reproduction health control. Methods: The subjects of the present research were male-to-female transgenders living in the town of Singaraja. The research applied a qualitative approach. Data collection in this research was conducted through in-depth interview and observation. Results: The results of the study exposed 1) the existence of waria transgender community in Singaraja observed from their active participation in social events such as taking the roles of counsellors in the campaign of prevention and control of HIV/AIDS with the Local Commission of AIDS Control and other foundations; 2) the sexual services provided by waria transgenders which were performed in squeeze method, oral and anal sex which could be categorized as HIV/AIDS high-risk sexual behaviours, while the consistency in doing safe sex among the trangenders in Singaraja showed that most of the waria transgenders (80%) were aware of the urgency of using condoms during sexual intercourse; and 3) the low participation of the waria transgenders in Singaraja in regular reproduction health check up at the local Centre of Public Health Service was caused by their negative perception about being examined by female doctors. Conclucions: Waria in singaraja categorized as HIV/AIDS high-risk sexual behaviours but they do have consistency in doing safe sex by using condoms. They have a negative psychological perception about being examined by female doctors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=waria%20transgenders" title="waria transgenders">waria transgenders</a>, <a href="https://publications.waset.org/abstracts/search?q=sexual%20behaviours" title=" sexual behaviours"> sexual behaviours</a>, <a href="https://publications.waset.org/abstracts/search?q=reproduction%20health" title=" reproduction health"> reproduction health</a>, <a href="https://publications.waset.org/abstracts/search?q=hiv%2Faids" title=" hiv/aids"> hiv/aids</a> </p> <a href="https://publications.waset.org/abstracts/50504/the-perspective-of-waria-transgenders-in-singaraja-on-their-reproduction-health" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50504.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">248</span> Investigation the Difference of Several Hormones Correlated to Reproduction between Infertile and Fertile Dairy Cows</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20M.%20Mutlag">Ali M.

The direct instruction of basic animal reproduction concepts in students enrolled in veterinary medicine programs allows them to elucidate the biological and molecular mechanisms that perpetuate the animal species in an ecosystem. Therefore, universities must implement didactic strategies that facilitate the teaching and learning processes for students and, in turn, enrich learning environments. Objective: to evaluate the effect of the use of a didactic textbook on the level of theoretical knowledge in embryo-maternal recognition for veterinary medicine students. Methods: the participants (n=24) were divided into two experimental groups: control (Ctrl) and treatment (Treat). Both groups received 4 hours of theoretical training regarding the basic concepts in bovine embryo-maternal recognition. However, the Treat group was also exposed to a guided lecture and the activity play-to-learn from a cow reproduction didactic textbook. A pre-test and a post-test were applied to assess the prior and subsequent knowledge in the participants. Descriptive statistics were applied to identify the success rates for each of the tests. Afterwards, a repeated measures model was applied where the effect of the intervention was considered. Results: no significant difference (p>0,05) was observed in the number of right answers for groups Ctrl (54,2%±12,7) and Treat (40,8%±16,8) in the pre-test. There was no difference (p>0,05) compering the number of right answers in Ctrl pre-test (54,2%±12,7) and post-test (60,8±18,8). However, the Treat group showed a significant (p>0,05) difference in the number of right answers when comparing pre-test (40,8%±16,8) and post-test (71,7%±14,7). Finally, after the theoretical training and the didactic activity in the Treat group, an increase of 10.9% (p<0,05) in the number of right answers was found when compared with the Ctrl group. Conclusion: the use of didactic tools that include guided lectures and activities like play-to-learn from a didactic textbook enhances the level of knowledge in an animal reproduction course for veterinary medicine students. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=animal%20reproduction" title="animal reproduction">animal reproduction</a>, <a href="https://publications.waset.org/abstracts/search?q=pedagogic" title=" pedagogic"> pedagogic</a>, <a href="https://publications.waset.org/abstracts/search?q=level%20of%20knowledge" title=" level of knowledge"> level of knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20environment" title=" learning environment"> learning environment</a> </p> <a href="https://publications.waset.org/abstracts/171306/use-of-didactic-bibliographic-resources-to-improve-the-teaching-and-learning-processes-of-animal-reproduction-in-veterinary-science" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171306.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">65</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">245</span> Contribution to the Study of Phenotypic, Reproduction and Growth Parameters of Sheep in Eastern Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Titaouine">Mohammed Titaouine</a>, <a href="https://publications.waset.org/abstracts/search?q=Toufik%20Meziane"> Toufik Meziane</a>, <a href="https://publications.waset.org/abstracts/search?q=Kahramen%20Deghnouche"> Kahramen Deghnouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanane%20Mohamdi"> Hanane Mohamdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabil%20Mohamdi"> Nabil Mohamdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to better understand the morphological characters and the zootechniques measures of sheeps races in the in South-East Algeria, a study that was conducted on 1344 heads, taken from 8 farms in different parts of the region, namely T’kout 1, T’kout 2, Tafrent, Barika, Sidi-Okba, Biskra, Ouled-Djellal and Msila. The results from the present study showed significant differences in the group of 14 morphological studied variables, the body length is the most important variable. Reproduction performance of 160 ewes and growth performances of 56 lambs were analysed. The analyses of the data showed that the ewes have a fertility level of 69%, a prolificacy level of 114% and a fecundity level of 79%. Lambs weigh 3.5kg at birth, 9.38kg at 30d, 13.45kg at 60d, 16.91kg at 90d and 21.51 kg at 120d. The speed of the growth level 0.20kg/d from birth to 30d, 0.14 kg/d between 30d and 60d, 0.12kg/d between 60d and 90d and 0.15kg/d between 90d and 120d. The simple born lambs were more heavy than the double born lambs. By contrast, sex was not significant for all the variables except the weight at 60d, the birth month has a significant effect on the weight at birth, at 30d, at 60d and it was no significant for the weight at 90d and at 120d.The flocks born on September, October, November, and December were more heavy than the flocks born on January, February, and March. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=morphological%20%20characterization" title="morphological characterization">morphological characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=reproduction%20performance" title=" reproduction performance"> reproduction performance</a>, <a href="https://publications.waset.org/abstracts/search?q=growth%20performances" title=" growth performances"> growth performances</a>, <a href="https://publications.waset.org/abstracts/search?q=algeria" title=" algeria"> algeria</a> </p> <a href="https://publications.waset.org/abstracts/15089/contribution-to-the-study-of-phenotypic-reproduction-and-growth-parameters-of-sheep-in-eastern-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15089.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">498</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">244</span> Factors Affecting Reproductive Behaviour of Married Women in Sudan: Acase of Shendi Town</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hamed">Mohamed Hamed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Population studies, essentially deals with the size, growth, and distribution of the population in a given area. Size, growth, and distribution are determined by three major factors, which are reproduction, mortality, and migration. Of these factors, reproduction is a potent socio-demographic force in vital process of population growth. It is a major component of population growth, and has crucial role in population dynamic, because it measures the rate at which a population increased. In fact the most striking feature of human reproduction is its variation. Its levels are vary widely among nations, countries, geographic regions, ethnic. The variations of reproductive behaviour among married women have been empirically documented in a large numbers of countries. For instance, many researchers in developing and developed countries investigated the differential of reproductive behaviour among married women. Most of these studies found that reproductive behaviour is strongly influenced by the socioeconomic and biological factors.Such as education, income, employment of women, marriage pattern, age at marriage, contraceptive use, education, and employment. However, the above socioeconomic and biological factors are determined by cultural factors surrounded by married women. So, this study is going to find out the effect of culture on reproductive behaviour among married women in Sudan, a case of Shendi town. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fertilty%20pattern" title="fertilty pattern">fertilty pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=sudan" title=" sudan"> sudan</a>, <a href="https://publications.waset.org/abstracts/search?q=shendi%20town" title=" shendi town"> shendi town</a>, <a href="https://publications.waset.org/abstracts/search?q=factors%20affecting%20reproductive%20behaviour" title="factors affecting reproductive behaviour">factors affecting reproductive behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=married%20women" title=" married women"> married women</a> </p> <a href="https://publications.waset.org/abstracts/14043/factors-affecting-reproductive-behaviour-of-married-women-in-sudan-acase-of-shendi-town" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14043.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">300</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">243</span> Beliefs on Reproduction of Women in Fish Port Community: An Explorative Study on the Beliefs on Conception, Childbirth, and Maternal Care of Women in Navotas Fish Port Community</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marie%20Kristel%20A.%20Gabawa">Marie Kristel A.

These 2 barangays are the nearest residential community within the Navotas Fish Port Complex (NFPC). Data gathered will be analyzed using grounded-theory method of analysis, with the theories of cultural materialism and equity feminism as foundation. Survey questionnaires, key informant interviews, and focus group discussions will be utilized in gathering data. Further, the presentation of data will be recommended to health program initiators and use the data gathered as a tool to customize FP/MCH programs to the perception and beliefs of women residing in NBBS1and NBBS2, and to aid any misinformation for FP/MCH techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beliefs%20on%20reproduction" title="beliefs on reproduction">beliefs on reproduction</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20port%20community" title=" fish port community"> fish port community</a>, <a href="https://publications.waset.org/abstracts/search?q=family%20planning" title=" family planning"> family planning</a>, <a href="https://publications.waset.org/abstracts/search?q=maternal%20and%20child%20health%20care" title=" maternal and child health care"> maternal and child health care</a>, <a href="https://publications.waset.org/abstracts/search?q=Navotas" title=" Navotas"> Navotas</a> </p> <a href="https://publications.waset.org/abstracts/42532/beliefs-on-reproduction-of-women-in-fish-port-community-an-explorative-study-on-the-beliefs-on-conception-childbirth-and-maternal-care-of-women-in-navotas-fish-port-community" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42532.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">259</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">242</span> Mackerel (Scomber Australasicus) Reproduction in Northeastern Taiwan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunarti%20Sinaga">Sunarti Sinaga</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsueh-Jung%20Lu"> Hsueh-Jung Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jia-Rong%20Lin"> Jia-Rong Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Blue mackerel (Scomber australasicus) is a crucial target species for Taiwan coastal fisheries and has maintained its status as the highest-produced species. Timely measurement of spawning status is crucial for determining the correct management strategy for this species. The objective of this study was to determine size at maturity, fecundity, batch fecundity, and spawning frequency on the basis of samples collected from Nan-Fang-Ao fishing port in Yilan during the spawning season from 2017 to 2019. Histological sections indicated that the blue mackerel are multiple spawners. A higher percentage of female fish spawned at the peak of the gonadosomatic index. The 50% sizes at maturity were 32.02, 32.13, and 29.64 cm. Mean total fecundity (batch fecundity) was 165 (103), 229 (96), and 210 (68) oocytes per ovary-free weight (g) for 2017, 2018, and 2019, respectively; fecundity was determined through observation of postovulatory follicles (POFs). The spawning frequencies (spawning fraction) in 2017, 2018, and 2019 were 3–10 days (0.13), 4–14 days (0.08), and 4–12 days (0.08), respectively. The spawning frequencies determined through the 3 estimated methods, namely the sums of (a) hydrated and Day 0 POFs; (b) Day 1+ POFs, and (c) all data combined, were 1 spawning event per 8, 10, and 9 days, respectively. The reproduction of the blue mackerel was greater in 2017 than it was in 2018 or 2019, as indicated by the higher batch fecundity and shorter spawning seasons. Environmental factors should also be considered as a major factor influencing successful reproduction and the spawning season. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=scomber%20australasicus" title="scomber australasicus">scomber australasicus</a>, <a href="https://publications.waset.org/abstracts/search?q=spawning%20frequency" title=" spawning frequency"> spawning frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=batch%20fecundity" title=" batch fecundity"> batch fecundity</a>, <a href="https://publications.waset.org/abstracts/search?q=fecundity" title=" fecundity"> fecundity</a> </p> <a href="https://publications.waset.org/abstracts/149287/mackerel-scomber-australasicus-reproduction-in-northeastern-taiwan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149287.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">103</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">241</span> Modelling the Effect of Distancing and Wearing of Face Masks on Transmission of COVID-19 Infection Dynamics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nurudeen%20Oluwasola%20Lasisi">Nurudeen Oluwasola Lasisi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The COVID-19 is an infection caused by coronavirus, which has been designated as a pandemic in the world. In this paper, we proposed a model to study the effect of distancing and wearing masks on the transmission of COVID-19 infection dynamics. The invariant region of the model is established. The COVID-19 free equilibrium and the reproduction number of the model were obtained. The local and global stability of the model is determined using the linearization technique method and Lyapunov method. It was found that COVID-19 free equilibrium state is locally asymptotically stable in feasible region Ω if R₀ < 1 and globally asymptomatically stable if R₀ < 1, otherwise unstable if R₀ > 1. More so, numerical analysis and simulations of the dynamics of the COVID-19 infection are presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distancing" title="distancing">distancing</a>, <a href="https://publications.waset.org/abstracts/search?q=reproduction%20number" title=" reproduction number"> reproduction number</a>, <a href="https://publications.waset.org/abstracts/search?q=wearing%20of%20mask" title=" wearing of mask"> wearing of mask</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20and%20global%20stability" title=" local and global stability"> local and global stability</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission" title=" transmission"> transmission</a> </p> <a href="https://publications.waset.org/abstracts/129529/modelling-the-effect-of-distancing-and-wearing-of-face-masks-on-transmission-of-covid-19-infection-dynamics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129529.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">138</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">240</span> Stability Analysis of a Human-Mosquito Model of Malaria with Infective Immigrants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisha%20Budhwar">Nisha Budhwar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunita%20Daniel"> Sunita Daniel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we analyse the stability of the SEIR model of malaria with infective immigrants which was recently formulated by the authors. The model consists of an SEIR model for the human population and SI Model for the mosquitoes. Susceptible humans become infected after they are bitten by infectious mosquitoes and move on to the Exposed, Infected and Recovered classes respectively. The susceptible mosquito becomes infected after biting an infected person and remains infected till death. We calculate the reproduction number R0 using the next generation method and then discuss about the stability of the equilibrium points.

This technique has the potential to identify protein biomarkers of a disease states. In this study which was performed on bovine ovarian follicular cysts (BOFC), eight proteins are over expressed in BOFC that these proteins could be useful biomarkers for BOFC. The difference between serum proteome pattern cows affected by postpartum endometritis with healthy cows revealed that concentrations orosomucoid was decreased in endometritis. The comparison proteome of brucella abortus between laboratory adapted strains and clinical isolates could be useful to better understand this disease and vaccine development. Proteomics experiments identified new proteins and pathways that may be important in future hypothesis-driven studies of glucocorticoid-induced immunosuppression. Understanding the molecular mechanisms of effective parameters on male fertility is essential for obtaining high reproductive efficiency by decreasing cost and time. The investigations on proteome of high fertility spermatozoa indicated that expression of some proteins such as casein kinase 2 (CKII) prime poly peptide and tyrosine kinase in high fertility spermatozoa was higher compared to low fertility spermatozoa. Also, some evidence has indicated that variation in protein types and amounts in seminal fluid regulates fertility indexes in dairy bull. In conclusion, proteomics is a useful technique for discovering drugs, vaccine development, and diagnosis disease by biomarkers and improvement of reproduction efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=proteomics" title="proteomics">proteomics</a>, <a href="https://publications.waset.org/abstracts/search?q=reproduction" title=" reproduction"> reproduction</a>, <a href="https://publications.waset.org/abstracts/search?q=biomarker" title=" biomarker"> biomarker</a>, <a href="https://publications.waset.org/abstracts/search?q=immunity" title=" immunity"> immunity</a> </p> <a href="https://publications.waset.org/abstracts/10854/proteomics-application-in-disease-diagnosis-and-reproduction-improvement-in-cow" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10854.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">238</span> The Factors Constitute the Interaction between Teachers and Students: An Empirical Study at the Notion of Framing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tien-Hui%20Chiang">Tien-Hui Chiang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The code theory, proposed by Basil Bernstein, indicates that framing can be viewed as the core element in constituting the phenomenon of cultural reproduction because it is able to regulate the transmission of pedagogical information. Strong framing increases the social relation boundary between a teacher and pupils, which obstructs information transmission, so that in order to improve underachieving students’ academic performances, teachers need to reduce to strength of framing. Weak framing enables them to transform academic knowledge into commonsense knowledge in daily life language. This study posits that most teachers would deliver strong framing due to their belief mainly confined within the aspect of instrumental rationality that deprives their critical minds. This situation could make them view the normal distribution bell curve of students’ academic performances as a natural outcome. In order to examine the interplay between framing, instrumental rationality and pedagogical action, questionnaires were completed by over 5,000 primary school teachers in Henan province, China, who were stratified sample. The statistical results show that most teachers employed psychological concepts to measure students’ academic performances and, in turn, educational inequity was legitimatized as a natural outcome in the efficiency-led approach. Such efficiency-led minds made them perform as the agent practicing the mechanism of social control and in turn sustaining the phenomenon of cultural reproduction. <p
