undergo changes in their clinical properties such as changes in roughness of the restoration's surface. An increase of surface roughness accelerates bacterial colonization and plaque maturation. It can be prevented by mechanically clean the tooth surface by brushing the teeth using toothpaste. Toothpaste may contain abrasives materials that usually found in whitening toothpaste. Those abrasive materials could increase the roughness of the restoration`s surface. Glass ionomer cement (GIC) is one of the restorative material widely used to this day. GC America has made an innovation called EQUIA to improve their wear resistance by coating the surface of GIC using G-Coat Plus. Objective: To determine the effect of teeth was brushing with whitening and non-whitening toothpaste to the surface roughness of coated and uncoated restoration (GIC). Methods: This research was a laboratory experimental with pretest-posttest group design. There were 28 samples which were divided into 2 groups. The first group was brushed with whitening toothpaste and the second group was brushed with non-whitening toothpaste. Each group was divided into group which coated by G-Coat Plus and group which left uncoated. The value of surface roughness was measured by using Roughness Tester. The data was analyzed by using independent t-test to determine differences between the surface roughness of coated samples and uncoated samples brushed with whitening and non-whitening toothpaste. Result: It was found that average roughness differences before and after being brushed by whitening toothpaste were smaller in coated samples than in uncoated samples (0.07 ± 0.09 < 0.12 ± 0.02). Similar results were also found in samples brushed by non-whitening toothpaste (0.02 ± 0.01 0.03 ± 0.01). The differences of average roughness in samples brushed with non-whitening toothpaste were smaller than samples brushed with whitening toothpaste. Conclusion: The data showed there were statistically significant differences between the surface roughness of coated samples and uncoated samples brushed with non-whitening toothpaste (p < 0.05) but the was no statistically significant to samples brushed with whitening toothpaste (p > 0.05). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=surface%20roughness" title="surface roughness">surface roughness</a>, <a href="https://publications.waset.org/abstracts/search?q=toothpaste" title=" toothpaste"> toothpaste</a>, <a href="https://publications.waset.org/abstracts/search?q=EQUIA" title=" EQUIA"> EQUIA</a>, <a href="https://publications.waset.org/abstracts/search?q=coating" title=" coating"> coating</a> </p> <a href="https://publications.waset.org/abstracts/66444/the-effect-of-tooth-brushing-with-whitening-and-non-whitening-tooth-paste-on-surface-roughness-of-coated-and-uncoated-glass-ionomer-cement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66444.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">247</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">9</span> Association between Caries Status of First Permanent Molar with Oral Health Care Practice in Children Aged 9-12 Years in Lubuk Kilangan, Padang City</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cytha%20Nilam%20Chairani">Cytha Nilam Chairani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ditha%20Noviantika"> Ditha Noviantika</a>, <a href="https://publications.waset.org/abstracts/search?q=Hidayati%20Amir"> Hidayati Amir</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurul%20Khairiyah"> Nurul Khairiyah</a>, <a href="https://publications.waset.org/abstracts/search?q=Siti%20Rahmadita"> Siti Rahmadita</a>, <a href="https://publications.waset.org/abstracts/search?q=Fadila%20Khairani"> Fadila Khairani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Dental caries is one of the most common diseases with high prevalence in children. The first permanent molar (FPM) has an essential role in establishing the occlusion. Nevertheless, FPM is very prone to caries because of various factors, such as their anatomical structure and early emergence in oral cavity. It is due to the little knowledge from parents and children regarding the timing of emergence of FPM in oral cavity which is still considered as primary teeth. Furthermore, the lack of knowledge from parents and children may affect their oral hygiene practice resulting to carious process. Objective: The aim of this study was to assess the status of FPM caries and its association with children’s oral hygiene practice in 9-12-year-old school children in Lubuk Kilangan Community Health Centre, Padang City. Methods: A cross-sectional study was performed in 50 school children (9-12 years old) using random sampling technique from two randomly selected schools in Lubuk Kilangan Community Health Centre, Padang City. A questionnaire was developed from other studies consisting of four closed ended questions regarding oral health practice. The data obtained were analyzed statistically using Mann-Whitney Test to assess the status of FPM caries and its association with children’s oral hygiene practice. Results: The results showed that 32% of children had FPMs sound and the remaining 68% had FPMs carious which were grouped into 1-2 FPMs carious (60%) and 3-4 FPMs carious (8%). The caries status of mandibular FPM (64%) was higher compared to maxillary FPM (10%). Conclusion: There was significant association in subject who did not visit dentist in the last 6 months which had more carious FPMs compared to subject who visited dentist (p < 0.05). There was no significant association between the status of FPM caries and knowledge of the timing eruption of FPM, oral hygiene instruction from parents and tooth brushing (p > 0.05). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dental%20caries" title="dental caries">dental caries</a>, <a href="https://publications.waset.org/abstracts/search?q=children" title=" children"> children</a>, <a href="https://publications.waset.org/abstracts/search?q=first%20permanent%20molar" title=" first permanent molar"> first permanent molar</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20hygiene%20practice" title=" oral hygiene practice"> oral hygiene practice</a> </p> <a href="https://publications.waset.org/abstracts/71581/association-between-caries-status-of-first-permanent-molar-with-oral-health-care-practice-in-children-aged-9-12-years-in-lubuk-kilangan-padang-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71581.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">275</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">8</span> Estimation of Leachate Generation from Municipal Solid Waste Landfills in Selangor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tengku%20Nilam%20Baizura">Tengku Nilam Baizura</a>, <a href="https://publications.waset.org/abstracts/search?q=Noor%20Zalina%20Mahmood"> Noor Zalina Mahmood</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Malaysia, landfilling is the most preferred method and most of it does not have the proper leachate treatment system which can cause environmental problems. Leachate is the major factor to river water pollution since most landfills are located near the river which is the main water resource for the country. The study aimed to estimate leachate production from landfills in Selangor. A simple mathematical modelling was used for the calculation of annual leachate volume. The estimate of identified landfill area (A) using Google Earth was multiplied by the annual rainfall (R). The product is expressed as volume (V). The data indicate that the leachate production is high even it is fully closed. It is important to design the efficient landfill and proper leachate treatment processes especially for the old/closed landfill. Extensive monitoring will be required to predict future impact. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=landfill" title="landfill">landfill</a>, <a href="https://publications.waset.org/abstracts/search?q=leachate" title=" leachate"> leachate</a>, <a href="https://publications.waset.org/abstracts/search?q=municipal%20solid%20waste%20management" title=" municipal solid waste management"> municipal solid waste management</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20disposal" title=" waste disposal"> waste disposal</a> </p> <a href="https://publications.waset.org/abstracts/43142/estimation-of-leachate-generation-from-municipal-solid-waste-landfills-in-selangor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43142.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">370</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">7</span> Mathematical Modeling for Diabetes Prediction: A Neuro-Fuzzy Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vijay%20Kr.%20Yadav">Vijay Kr.

The diesel engines are widely used in the world because it has the most excellent combustion efficiency than other types of internal combustion engine.  However, the exhaust emissions of it produce pollutants that are harmful to human health and the environment. Therefore, natural gas used as an alternative fuel using on compression ignition engine to respond those environment issues. This paper aims to discuss the comparison of the technical characteristics and exhaust gases emission from conventional diesel engine and dual fuel diesel engine. According to the study, the dual fuel engine applications have a lower compression pressure and has longer ignition delay compared with normal diesel mode. The engine power is decreased at dual fuel mode. However, the exhaust gases emission on dual fuel engine significantly reduce the nitrogen oxide (NOx), carbon dioxide (CO<sub>2</sub>) and particular metter (PM) emissions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diesel%20engine" title="diesel engine">diesel engine</a>, <a href="https://publications.waset.org/abstracts/search?q=dual%20fuel%20diesel%20engine" title=" dual fuel diesel engine"> dual fuel diesel engine</a>, <a href="https://publications.waset.org/abstracts/search?q=emission%20reduction" title=" emission reduction"> emission reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=technical%20characteristics" title=" technical characteristics"> technical characteristics</a> </p> <a href="https://publications.waset.org/abstracts/61852/study-of-dual-fuel-engine-as-environmentally-friendly-engine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61852.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">307</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">5</span> Dynamics of a Susceptible-Infected-Recovered Model along with Time Delay, Modulated 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=Abhishek%20Kumar">Abhishek Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Nilam"> Nilam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As we know that, time delay exists almost in every biological phenomenon. 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">156</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">4</span> Study of the Economic Development of Border Areas Malinau District</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Indri%20Nilam%20Sari">Indri Nilam Sari</a>, <a href="https://publications.waset.org/abstracts/search?q=Aris%20Subagiyo"> Aris Subagiyo</a>, <a href="https://publications.waset.org/abstracts/search?q=Nindya%20Sari"> Nindya Sari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Malinau Regency border area is an area which is based on the RTRWN and the development priority.

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">2</span> Analysis of Secondary Peak in Hα Emission Profile during Gas Puffing in Aditya Tokamak</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harshita%20Raj">Harshita Raj</a>, <a href="https://publications.waset.org/abstracts/search?q=Joydeep%20Ghosh"> Joydeep Ghosh</a>, <a href="https://publications.waset.org/abstracts/search?q=Rakesh%20L.%20Tanna"> Rakesh L.

This requires a fair understanding of fuel recycling in order to optimize the gas fueling. In Aditya tokamak, multiple gas puffs are used in a precise and controlled manner, for hydrogen fueling during the flat top of plasma discharge which has been instrumental in achieving discharges with enhanced density as well as energy confinement time. Following each gas puff, we observe peaks in temporal profile of Hα emission, Soft X-ray (SXR) and chord averaged electron density in a number of discharges, indicating efficient gas fueling. Interestingly, Hα temporal profile exhibited an additional peak following the peak corresponding to each gas puff. These additional peak Hα appeared in between the two gas puffs, indicating the presence of a secondary hydrogen source apart from the gas puffs. A thorough investigation revealed that these secondary Hα peaks coincide with Hard X- ray bursts which come from the interaction of runaway electrons with vessel limiters. This leads to consider that the runaway electrons (REs), which hit the wall, in turn, bring out the absorbed hydrogen and oxygen from the wall and makes the interaction of REs with limiter a secondary hydrogen source. These observations suggest that runaway electron induced recycling should also be included in recycling particle source in the particle balance calculations in tokamaks. Observation of two Hα peaks associated with one gas puff and their roles in enhancing and maintaining plasma density in Aditya tokamak will be discussed in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fusion" title="fusion">fusion</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20fueling" title=" gas fueling"> gas fueling</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling" title=" recycling"> recycling</a>, <a href="https://publications.waset.org/abstracts/search?q=Tokamak" title=" Tokamak"> Tokamak</a>, <a href="https://publications.waset.org/abstracts/search?q=Aditya" title=" Aditya"> Aditya</a> </p> <a href="https://publications.waset.org/abstracts/67668/analysis-of-secondary-peak-in-ha-emission-profile-during-gas-puffing-in-aditya-tokamak" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67668.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">402</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">1</span> Determinants of Child Nutritional Inequalities in Pakistan: Regression-Based Decomposition Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nilam%20Bano">Nilam Bano</a>, <a href="https://publications.waset.org/abstracts/search?q=Uzma%20Iram"> Uzma Iram</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Globally, the dilemma of undernutrition has become a notable concern for the researchers, academicians, and policymakers because of its severe consequences for many centuries. The nutritional deficiencies create hurdles for the people to achieve goals related to live a better lifestyle. Not only at micro level but also at the macro level, the consequences of undernutrition affect the economic progress of the country. The initial five years of a child’s life are considered critical for the physical growth and brain development. In this regard, children require special care and good quality food (nutrient intake) to fulfill their nutritional demand of the growing body. Having the sensitive stature and health, children specially under the age of 5 years are more vulnerable to the poor economic, housing, environmental and other social conditions. Beside confronting economic challenges and political upheavals, Pakistan is also going through from a rough patch in the context of social development. Majority of the children are facing serious health problems in the absence of required nutrition. The complexity of this issue is getting severe day by day and specially children are left behind with different type of immune problems and vitamins and mineral deficiencies. It is noted that children from the well-off background are less likely affected by the undernutrition. In order to underline this issue, the present study aims to highlight the existing nutritional inequalities among the children of under five years in Pakistan. Moreover, this study strives to decompose those factors that severely affect the existing nutritional inequality and standing in the queue to capture the consideration of concerned authorities. Pakistan Demographic and Health Survey 2012-13 was employed to assess the relevant indicators of undernutrition such as stunting, wasting, underweight and associated socioeconomic factors. The objectives were executed through the utilization of the relevant empirical techniques. Concentration indices were constructed to measure the nutritional inequalities by utilizing three measures of undernutrition; stunting, wasting and underweight. In addition to it, the decomposition analysis following the logistic regression was made to unfold the determinants that severely affect the nutritional inequalities. The negative values of concentration indices illustrate that children from the marginalized background are affected by the undernutrition more than their counterparts who belong from rich households. Furthermore, the result of decomposition analysis indicates that child age, size of a child at birth, wealth index, household size, parents’ education, mother’s health and place of residence are the most contributing factors in the prevalence of existing nutritional inequalities. Considering the result of the study, it is suggested to the policymakers to design policies in a way so that the health sector of Pakistan can stimulate in a productive manner. Increasing the number of effective health awareness programs for mothers would create a notable difference. Moreover, the education of the parents must be concerned by the policymakers as it has a significant association with the present research in terms of eradicating the nutritional inequalities among children. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concentration%20index" title="concentration index">concentration index</a>, <a
