Both algorithms are adapted using graph theory to generate feasible individuals, and the modified crossover is used for continuous variable of CGA. To demonstrate the performance and effectiveness of the proposed methods, a comparative analysis of CGA with PSO for network reconfiguration, on 33-node and 119-bus radial distribution system is presented.

In this context, more efforts and concerns have already been placed on the treatment and management of this waste. To mitigate their negative influences on the environment and society, it is necessary to establish appropriate strategies for e-waste management. Hence, this paper aims to review and analysis some useful strategies which have been applied in several countries to handle e-waste. Future perspectives on e-waste management are also suggested. The key findings found that, to manage e-waste successfully, it is necessary to establish effective reverse supply chains for e-waste, and raise public awareness towards the detrimental impacts of e-waste. The result of the research provides valuable insights to governments, policymakers in establishing e-waste management in a safe and sustainable manner. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=e-waste" title="e-waste">e-waste</a>, <a href="https://publications.waset.org/abstracts/search?q=e-waste%20management" title=" e-waste management"> e-waste management</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20assessment" title=" life cycle assessment"> life cycle assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling%20regulations" title=" recycling regulations"> recycling regulations</a> </p> <a href="https://publications.waset.org/abstracts/103633/strategies-for-e-waste-management-a-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103633.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">334</span> Influence of Synergistic Modification with Tung Oil and Heat Treatment on Physicochemical Properties of Wood</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luxi%20He">Luxi He</a>, <a href="https://publications.waset.org/abstracts/search?q=Tianfang%20Zhang"> Tianfang Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhengbin%20He"> Zhengbin He</a>, <a href="https://publications.waset.org/abstracts/search?q=Songlin%20Yi"> Songlin Yi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heat treatment has been widely recognized for its effectiveness in enhancing the physicochemical properties of wood, including hygroscopicity and dimensional stability. Nonetheless, the non-negligible volumetric shrinkage and loss of mechanical strength resulting from heat treatment may diminish the wood recovery and its product value. In this study, tung oil was used to alleviate heat-induced shrinkage and reduction in mechanical properties of wood during heat treatment. Tung oil was chosen as a modifier because it is a traditional Chinese plant oil that has been widely used for over a thousand years to protect wooden furniture and buildings due to its biodegradable and non-toxic properties. The effects of different heating media (air, tung oil) and their effective treatment parameters (temperature, duration) on the changes in the physical properties (morphological characteristics, pore structures, micromechanical properties), and chemical properties (chemical structures, chemical composition) of wood were investigated by using scanning electron microscopy, confocal laser scanning microscopy, atomic force microscopy, X-ray photoelectron spectroscopy, and dynamic vapor sorption. Meanwhile, the correlation between the mass changes and the color change, volumetric shrinkage, and hygroscopicity was also investigated. The results showed that the thermal degradation of wood cell wall components was the most important factor contributing to the changes in heat-induced shrinkage, color, and moisture adsorption of wood. In air-heat-treated wood samples, there was a significant correlation between mass change and heat-induced shrinkage, brightness, and moisture adsorption. However, the presence of impregnated tung oil in oil-heat-treated wood appears to disrupt these correlations among physical properties. The results of micromechanical properties demonstrated a significant decrease in elastic modulus following high-temperature heat treatment, which was mitigated by tung oil treatment. Chemical structure and compositional analyses indicated that the changes in chemical structure primarily stem from the degradation of hemicellulose and cellulose, and the presence of tung oil created an oxygen-insulating environment that slowed down this degradation process. Morphological observation results showed that tung oil permeated the wood structure and penetrated the cell walls through transportation channels, altering the micro-morphology of the cell wall surface, obstructing primary water passages (e.g., vessels and pits), and impeding the release of volatile degradation products as well as the infiltration and diffusion of water. In summary, tung oil treatment represents an environmentally friendly and efficient method for maximizing wood recovery and increasing product value. This approach holds significant potential for industrial applications in wood heat treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tung%20oil" title="tung oil">tung oil</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20treatment" title=" heat treatment"> heat treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=physicochemical%20properties" title=" physicochemical properties"> physicochemical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20cell%20walls" title=" wood cell walls"> wood cell walls</a> </p> <a href="https://publications.waset.org/abstracts/179080/influence-of-synergistic-modification-with-tung-oil-and-heat-treatment-on-physicochemical-properties-of-wood" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179080.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">69</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">333</span> Analytical Design of IMC-PID Controller for Ideal Decoupling Embedded in Multivariable Smith Predictor Control System </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Le%20Hieu%20Giang">Le Hieu Giang</a>, <a href="https://publications.waset.org/abstracts/search?q=Truong%20Nguyen%20Luan%20Vu"> Truong Nguyen Luan Vu</a>, <a href="https://publications.waset.org/abstracts/search?q=Le%20Linh"> Le Linh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the analytical tuning rules of IMC-PID controller are presented for the multivariable Smith predictor that involved the ideal decoupling.

However, the generated descriptions of their systems are often less informative and attractive because of lacking training datasets or the limitation of these approaches, which often use templates or statistical methods. In this paper, we explore a method to generate production descriptions by using the GPT-2 model. In addition, we apply text paraphrasing and task-adaptive pretraining techniques to improve the qualify of descriptions generated from the GPT-2 model.

By using the simplified decoupling technique, the transfer function of decoupled apparent process is firstly separated into a set of n equivalent independent processes in terms of a ratio of the diagonal elements of original open-loop transfer function to those of dynamic relative gain array and the fraction – order PI controller is then developed for each control loops due to the Bode’s ideal transfer function that gives the desired fractional closed-loop response in the frequency domain. The simulation studies were carried out to evaluate the proposed design approach in a fair compared with the other existing methods in accordance with the structured singular value (SSV) theory that used to measure the robust stability of control systems under multiplicative output uncertainty. The simulation results indicate that the proposed method consistently performs well with fast and well-balanced closed-loop time responses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ideal%20transfer%20function%20of%20bode" title="ideal transfer function of bode">ideal transfer function of bode</a>, <a href="https://publications.waset.org/abstracts/search?q=fractional%20calculus" title=" fractional calculus"> fractional calculus</a>, <a href="https://publications.waset.org/abstracts/search?q=fractional%20order%20proportional%20integral%20%28FOPI%29%20controller" title=" fractional order proportional integral (FOPI) controller"> fractional order proportional integral (FOPI) controller</a>, <a href="https://publications.waset.org/abstracts/search?q=decoupling%20control%20system" title=" decoupling control system"> decoupling control system</a> </p> <a href="https://publications.waset.org/abstracts/50475/analytical-design-of-fractional-order-pi-controller-for-decoupling-control-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50475.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">331</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">328</span> Design of IMC-PID Controller Cascaded Filter for Simplified Decoupling Control System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Le%20Linh">Le Linh</a>, <a href="https://publications.waset.org/abstracts/search?q=Truong%20Nguyen%20Luan%20Vu"> Truong Nguyen Luan Vu</a>, <a href="https://publications.waset.org/abstracts/search?q=Le%20Hieu%20Giang"> Le Hieu Giang </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, the IMC-PID controller cascaded filter based on Internal Model Control (IMC) scheme is systematically proposed for the simplified decoupling control system. The simplified decoupling is firstly introduced for multivariable processes by using coefficient matching to obtain a stable, proper, and causal simplified decoupler. Accordingly, transfer functions of decoupled apparent processes can be expressed as a set of <em>n</em> equivalent independent processes and then derived as a ratio of the original open-loop transfer function to the diagonal element of the dynamic relative gain array. The IMC-PID controller in series with filter is then directly employed to enhance the overall performance of the decoupling control system while avoiding difficulties arising from properties inherent to simplified decoupling. Some simulation studies are considered to demonstrate the simplicity and effectiveness of the proposed method. Simulations were conducted by tuning various controllers of the multivariate processes with multiple time delays. The results indicate that the proposed method consistently performs well with fast and well-balanced closed-loop time responses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coefficient%20matching%20method" title="coefficient matching method">coefficient matching method</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20model%20control%20%28IMC%29%20scheme" title=" internal model control (IMC) scheme"> internal model control (IMC) scheme</a>, <a href="https://publications.waset.org/abstracts/search?q=PID%20controller%20cascaded%20filter" title=" PID controller cascaded filter"> PID controller cascaded filter</a>, <a href="https://publications.waset.org/abstracts/search?q=simplified%20decoupler" title=" simplified decoupler"> simplified decoupler</a> </p> <a href="https://publications.waset.org/abstracts/48781/design-of-imc-pid-controller-cascaded-filter-for-simplified-decoupling-control-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48781.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">442</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">327</span> Application of Fuzzy Logic to Design and Coordinate Parallel Behaviors for a Humanoid Mobile Robot</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Chan%20Hung">Nguyen Chan Hung</a>, <a href="https://publications.waset.org/abstracts/search?q=Mai%20Ngoc%20Anh"> Mai Ngoc Anh</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Xuan%20Ha"> Nguyen Xuan Ha</a>, <a href="https://publications.waset.org/abstracts/search?q=Tran%20Xuan%20Duc"> Tran Xuan Duc</a>, <a href="https://publications.waset.org/abstracts/search?q=Dang%20Bao%20Lam"> Dang Bao Lam</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Hoang%20Viet"> Nguyen Hoang Viet</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a design and implementation of a navigation controller for a humanoid mobile robot platform to operate in indoor office environments.

The need for improvements in reliable water supply systems is urgent with the increasing living standards of regions. In this study, a suitable shortage index capable of multi-aspect description - frequency, magnitude, and duration - is adopted to more accurately describe the characteristics of a shortage situation. The values of the index were determined to cope with the increasing need for reliability. There are four reservoirs in series located on the Be River of the Dong Nai River Basin in Southern Vietnam. The primary purpose of the three upstream reservoirs is hydropower generation while the primary purpose of the fourth is water supply. A compromise between hydropower generation and water supply can be negotiated for these four reservoirs to reduce the severity of water shortages. A generalized water allocation model was applied to simulate the water supply, and hydropower generation of various management alternatives and the system’s reliability was evaluated using the adopted multiple shortage indices. Modifying management policies of water resources using data-based indexes can improve the reliability of water supply. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cascade%20reservoirs" title="cascade reservoirs">cascade reservoirs</a>, <a href="https://publications.waset.org/abstracts/search?q=hydropower" title=" hydropower"> hydropower</a>, <a href="https://publications.waset.org/abstracts/search?q=shortage%20index" title=" shortage index"> shortage index</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20supply" title=" water supply"> water supply</a> </p> <a href="https://publications.waset.org/abstracts/84967/investigating-the-behavior-of-water-shortage-indices-for-performance-evaluation-of-a-water-resources-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84967.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">269</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">325</span> Methods of Interpolating Temperature and Rainfall Distribution in Northern Vietnam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thanh%20Van%20Hoang">Thanh Van Hoang</a>, <a href="https://publications.waset.org/abstracts/search?q=Tien%20Yin%20Chou"> Tien Yin Chou</a>, <a href="https://publications.waset.org/abstracts/search?q=Yao%20Min%20Fang"> Yao Min Fang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi%20Min%20Huang"> Yi Min Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xuan%20Linh%20Nguyen"> Xuan Linh Nguyen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reliable information on the spatial distribution of annual rainfall and temperature is essential in research projects relating to urban and regional planning. This research presents results of a classification of temperature and rainfall in the Red River Delta of northern Vietnam based on measurements from seven meteorological stations (Ha Nam, Hung Yen, Lang, Nam Dinh, Ninh Binh, Phu Lien, Thai Binh) in the river basin over a thirty-years period from 1982-2011. The average accumulated rainfall trends in the delta are analysed and form the basis of research essential to weather and climate forecasting. This study employs interpolation based on the Kriging Method for daily rainfall (min and max) and daily temperature (min and max) in order to improve the understanding of sources of variation and uncertainly in these important meteorological parameters. To the Kriging method, the results will show the different models and the different parameters based on the various precipitation series.

Those low-rise buildings have created well-knitted, robust communities, so much to the point that in most complexes, all families in one housing block would know each other, occasionally interact and provide supports in need. To understand how the community of collective housing complexes have developed and maintained in order to adapt their advantages into modern housing designs, the study is executed on the site of Nguyen Cong Tru KTT. This is one of the oldest KTT in Hanoi, completed in 1954. The complex also has an unique characteristic that is closely related to its community: the symbiotic relationship with Hom – a flea market that has been co-developing with Nguyen Cong Tru KTT since its beginning. The research consists of three phases: the first phase is a sociological investigation with Nguyen Cong Tru KTT’s current residents and a site survey on the complex’s economic and architectural characteristics. In the second phase, the collected data is analyzed to find out people’s opinions with the KTT’s concerning their satisfaction with the current housing status, floor plan organization, community, the relationship between the KTT’s dedicated public spaces with the flea market and their usage. Simultaneously, the master plan and gathered information regarding current architectural characteristics of the complex are also inspected. On the third phase, the analyses’ results will provide information regarding the issues, positive trends and significant historical features of the complex’s architecture in order to generate suitable proposals for the redesigning project of Nguyen Cong Tru KTT, a design focused on vitalizing modern apartments’ communities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collective%20house%20community" title="collective house community">collective house community</a>, <a href="https://publications.waset.org/abstracts/search?q=collective%20house%20public%20space" title=" collective house public space"> collective house public space</a>, <a href="https://publications.waset.org/abstracts/search?q=community-focused" title=" community-focused"> community-focused</a>, <a href="https://publications.waset.org/abstracts/search?q=redesigning%20Nguyen%20Cong%20Tru%20KTT" title=" redesigning Nguyen Cong Tru KTT"> redesigning Nguyen Cong Tru KTT</a>, <a href="https://publications.waset.org/abstracts/search?q=sociological%20investigation" title=" sociological investigation "> sociological investigation </a> </p> <a href="https://publications.waset.org/abstracts/68487/a-sociological-investigation-on-the-population-and-public-spaces-of-nguyen-cong-tru-a-soviet-style-collective-housing-complex-in-hanoi-in-regards-to-its-new-community-focused-architectural-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68487.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">363</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">323</span> A Novel Search Pattern for Motion Estimation in High Efficiency Video Coding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Phong%20Nguyen">Phong Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Phap%20Nguyen"> Phap Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Thang%20Nguyen"> Thang Nguyen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> High Efficiency Video Coding (HEVC) or H.265 Standard fulfills the demand of high resolution video storage and transmission since it achieves high compression ratio. However, it requires a huge amount of calculation. Since Motion Estimation (ME) block composes about 80 % of calculation load of HEVC, there are a lot of researches to reduce the computation cost. In this paper, we propose a new algorithm to lower the number of Motion Estimation’s searching points. The number of computing points in search pattern is down from 77 for Diamond Pattern and 81 for Square Pattern to only 31. Meanwhile, the Peak Signal to Noise Ratio (PSNR) and bit rate are almost equal to those of conventional patterns.

Nevertheless, many of land use planning locations are facing protests from surrounding households due to environmental impacts. In addition, locations are planned completely based on the subjective decisions of planners who are unsupported by tools or scientific methods. Hence, this research aims to assist the decision-makers in evaluating the rationality of planning locations by developing a Spatial Decision Support System (SDSS) using approaches of Geographic Information System (GIS)-based technology, Analytic Hierarchy Process (AHP) multi-criteria-based technique and Fuzzy set theory. An ArcGIS Desktop add-ins named SDSS-LUPA was developed to support users analyzing data and presenting results in friendly format. The Fuzzy-AHP method has been utilized as analytic model for this SDSS. There are 18 planned locations in Hung Ha district (Thai Binh province, Vietnam) as a case study. The experimental results indicated that the assessment threshold higher than 0.65 while the 18 planned locations were irrational because of close to residential areas or close to water sources. Some potential sites were also proposed to the authorities for consideration of land use planning changes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytic%20hierarchy%20process" title="analytic hierarchy process">analytic hierarchy process</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20set%20theory" title=" fuzzy set theory"> fuzzy set theory</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20use%20planning" title=" land use planning"> land use planning</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20decision%20support%20system" title=" spatial decision support system"> spatial decision support system</a> </p> <a href="https://publications.waset.org/abstracts/70019/developing-a-spatial-decision-support-system-for-rationality-assessment-of-land-use-planning-locations-in-thai-binh-province-vietnam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70019.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">379</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">321</span> Numerical Modelling of a Vacuum Consolidation Project in Vietnam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Trong%20Nghia">Nguyen Trong Nghia</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Huu%20Uy%20Vu"> Nguyen Huu Uy Vu</a>, <a href="https://publications.waset.org/abstracts/search?q=Dang%20Huu%20Phuoc"> Dang Huu Phuoc</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjay%20Kumar%20Shukla"> Sanjay Kumar Shukla</a>, <a href="https://publications.waset.org/abstracts/search?q=Le%20Gia%20Lam"> Le Gia Lam</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Van%20Cuong"> Nguyen Van Cuong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper introduces a matching scheme for selection of soil/drain properties in analytical solution and numerical modelling (axisymmetric and plane strain conditions) of a ground improvement project by using Prefabricated Vertical Drains (PVD) in combination with vacuum and surcharge preloading.

Our group previously reported high seroprevalence of CAV in chickens in northern Vietnam. In the present study, 330 tissue samples collected from commercial and breeder chicken farms in eleven provinces in northern Vietnam were tested for the CAV infection. We found that 157 out of 330 (47.58%) chickens were positive with CAV genes by real-time PCR method. Nine CAV strains obtained from the different location and time were forwarded to the full-length sequence of CAV VP1 gene. Phylogenetic analysis of the Vietnamese CAV vp1 gene indicated that the CAVs circulating in northern Vietnam were divided into three distinct genotypes, II, III, and V, but not clustered with the vaccine strains. Among the three genotypes, genotype III was the major one widely spread in Vietnam, and that included three sub-genotypes, IIIa, IIIb, and IIIc. The Vietnamese CAV strains were closely related to the Chinese, Taiwanese, and USA strains. All the CAV isolates had glutamine at amino acid position 394 in the VP1 gene, suggesting that they might be highly pathogenic strains. One strain was defined to be genotype V, which had not been reported for Vietnamese CAVs. Additional studies are required to further evaluate the pathogenicity of CAV strains circulating in Vietnam. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chicken%20anemia%20virus" title="chicken anemia virus">chicken anemia virus</a>, <a href="https://publications.waset.org/abstracts/search?q=genotype" title=" genotype"> genotype</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20characteristics" title=" genetic characteristics"> genetic characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=Vietnam" title=" Vietnam"> Vietnam</a> </p> <a href="https://publications.waset.org/abstracts/105191/genetic-characteristics-of-chicken-anemia-virus-circulating-in-northern-vietnam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105191.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">167</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">319</span> An Application of Hip Arthroscopy after Acute Injury - A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Le%20Nguyen%20Binh">Le Nguyen Binh</a>, <a href="https://publications.waset.org/abstracts/search?q=Luong%20Xuan%20Binh"> Luong Xuan Binh</a>, <a href="https://publications.waset.org/abstracts/search?q=Le%20Van%20Tuan"> Le Van Tuan</a>, <a href="https://publications.waset.org/abstracts/search?q=Tran%20Binh%20Duong"> Tran Binh Duong</a>, <a href="https://publications.waset.org/abstracts/search?q=Truong%20Nguyen%20Khanh%20Hung"> Truong Nguyen Khanh Hung</a>, <a href="https://publications.waset.org/abstracts/search?q=Do%20Le%20Hoang%20Son"> Do Le Hoang Son</a>, <a href="https://publications.waset.org/abstracts/search?q=Pham%20Quang%20Vinh"> Pham Quang Vinh</a>, <a href="https://publications.waset.org/abstracts/search?q=Hoang%20Quoc%20Huy"> Hoang Quoc Huy</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Bach"> Nguyen Bach</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Quoc%20Khanh%20Le"> Nguyen Quoc Khanh Le</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiunn%20Horng%20Kang"> Jiunn Horng Kang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Traumatic hip dislocation is an emergency in young adult which can cause avascular necrosis of femoral head or osteoarthritis of hip joint. The reasons for these may be the loose body of bony or chondral fragments, which are difficult to be detected on CT scan or MRI. In those cases, Hip arthroscopy may be the method of choice for diagnosis and treatment of loose bodies in hip joint after traumatic dislocation. Methods: A case report is performed. A 55-year-old male patient was under hip arthroscopy to retrieve the loose body in the right hip joint. Results: The patient’s hip was reduced under anesthesia in the opeation room. Xray and CT scan post-reduction showed that his right hip was wide and a small fragment of femoral head (< 5mm) locking inside the joint. A hip arthroscopy was done to take the fragment out. Post-operation, the patient went under rehabilition. After 6 months, he can walk with full-weight bearing; no further dislocaion was noted, and the Harris score was 84 points. Conclusions: Although acute traumatic injury of hip joint is usually treated with open surgeries, these methods have many drawbacks, such as soft tissue destruction, blood-loss,….Despite its technical requirement, hip arthroscopy is less invasive and effective treatment. Therefore, it may be an alternative treatment for a traumatic hip injury and can be applied frequently in the near future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hip%20dislocation" title="hip dislocation">hip dislocation</a>, <a href="https://publications.waset.org/abstracts/search?q=hip%20arthroscopy" title=" hip arthroscopy"> hip arthroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=hip%20osteoarthritis" title=" hip osteoarthritis"> hip osteoarthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=acute%20hip%20trauma" title=" acute hip trauma"> acute hip trauma</a> </p> <a href="https://publications.waset.org/abstracts/162276/an-application-of-hip-arthroscopy-after-acute-injury-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162276.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">86</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">318</span> An Assessment of Tai Chi Exercise on Cognitive Performance in Vietnamese Older Adults</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hung%20Manh%20Nguyen">Hung Manh Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Duong%20Dai%20Nguyen"> Duong Dai Nguyen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: To evaluate the effects of Tai Chi exercise on cognitive performance of community-dwelling elderly in Vinh city, Vietnam.

The ambiguity resolution method is an adaptive implementation of the coincidence algorithm, which is implemented on a two-dimensional (2D) range-velocity matrix to resolve range and velocity ambiguities simultaneously, with a proposed clustering filter to enhance the anti-error ability of the system. Here we consider the scenario of multiple target environments. The ghost target removal process, which is based on the power after Doppler processing, is proposed to mitigate ghosting detections to enhance the performance of ground-based radars using a short PRF schedule in multiple target environments. Simulation results on a ground-based pulsed Doppler radar model will be presented to show the effectiveness of the proposed approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ambiguity%20resolution" title="ambiguity resolution">ambiguity resolution</a>, <a href="https://publications.waset.org/abstracts/search?q=coincidence%20algorithm" title=" coincidence algorithm"> coincidence algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=medium%20PRF" title=" medium PRF"> medium PRF</a>, <a href="https://publications.waset.org/abstracts/search?q=ghosting%20removal" title=" ghosting removal"> ghosting removal</a> </p> <a href="https://publications.waset.org/abstracts/154205/ambiguity-resolution-for-ground-based-pulse-doppler-radars-using-multiple-medium-pulse-repetition-frequency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154205.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">316</span> Some Observations on the Preparation of Zinc Hydroxide Nitrate Nanoparticles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Krasimir%20Ivanov">Krasimir Ivanov</a>, <a href="https://publications.waset.org/abstracts/search?q=Elitsa%20Kolentsova"> Elitsa Kolentsova</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Nguyen"> Nguyen Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Peltekov"> Alexander Peltekov</a>, <a href="https://publications.waset.org/abstracts/search?q=Violina%20Angelova"> Violina Angelova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The nanosized zinc hydroxide nitrate has been recently estimated as perspective foliar fertilizer, which has improved zinc solubility, but low phytotoxicity, in comparison with ZnO and other Zn containing compounds.

The mechanism of this disease is a failure of hepatic excretion of copper to the bile, and it leads to copper deposits in the liver and other organs. Most clinical symptoms of Wilson’s disease can present as liver disease and/or neurologic disease. Objective: The goal of the study is prenatal diagnosis for pregnant women at high risk of Wilson’s disease in Northern Vietnam. Material and method: Three probands with clinically diagnosed liver disease were detected in the mutations of 21 exons and exon-intron boundaries of the ATP7B gene by direct Sanger-sequencing. Prenatal diagnoses were performed by amniotic fluid sampling from pregnant women in the 16th-18th weeks of pregnancy after the genotypes of parents with the probands were identified. Result: A total of three different mutations of the probands, including of S105*, P1052L, P1273G, were detected. Among three fetuses which underwent prenatal genetic testing, one fetus was homozygote; two fetuses were carriers. Conclusion: Genetic testing provided a useful method for prenatal diagnosis, and is a basis for genetic counseling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ATP7B%20gene" title="ATP7B gene">ATP7B gene</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20testing" title=" genetic testing"> genetic testing</a>, <a href="https://publications.waset.org/abstracts/search?q=prenatal%20diagnosis" title=" prenatal diagnosis"> prenatal diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=pedigree" title=" pedigree"> pedigree</a>, <a href="https://publications.waset.org/abstracts/search?q=Wilson%20disease" title=" Wilson disease"> Wilson disease</a> </p> <a href="https://publications.waset.org/abstracts/58248/application-of-atp7b-gene-mutation-analysis-in-prenatal-diagnosis-of-wilsons-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58248.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">455</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">314</span> Flood Planning Based on Risk Optimization: A Case Study in Phan-Calo River Basin in Vinh Phuc Province, Vietnam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Quang%20Kim">Nguyen Quang Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Thu%20Hien"> Nguyen Thu Hien</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Thien%20Dung"> Nguyen Thien Dung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flood disasters are increasing worldwide in both frequency and magnitude. Every year in Vietnam, flood causes great damage to people, property, and environmental degradation. The flood risk management policy in Vietnam is currently updated. The planning of flood mitigation strategies is reviewed to make a decision how to reach sustainable flood risk reduction. This paper discusses the basic approach where the measures of flood protection are chosen based on minimizing the present value of expected monetary expenses, total residual risk and costs of flood control measures. This approach will be proposed and demonstrated in a case study for flood risk management in Vinh Phuc province of Vietnam. Research also proposed the framework to find a solution of optimal protection level and optimal measures of the flood. It provides an explicit economic basis for flood risk management plans and interactive effects of options for flood damage reduction. The results of the case study are demonstrated and discussed which would provide the processing of actions helped decision makers to choose flood risk reduction investment options. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drainage%20plan" title="drainage plan">drainage plan</a>, <a href="https://publications.waset.org/abstracts/search?q=flood%20planning" title=" flood planning"> flood planning</a>, <a href="https://publications.waset.org/abstracts/search?q=flood%20risk" title=" flood risk"> flood risk</a>, <a href="https://publications.waset.org/abstracts/search?q=residual%20risk" title=" residual risk"> residual risk</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20optimization" title=" risk optimization"> risk optimization</a> </p> <a href="https://publications.waset.org/abstracts/87574/flood-planning-based-on-risk-optimization-a-case-study-in-phan-calo-river-basin-in-vinh-phuc-province-vietnam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87574.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">242</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">313</span> Enhancing the Stability of Vietnamese Power System - from Theory to Practical</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Edwin%20Lerch">Edwin Lerch</a>, <a href="https://publications.waset.org/abstracts/search?q=Dirk%20Audring"> Dirk Audring</a>, <a href="https://publications.waset.org/abstracts/search?q=Cuong%20Nguyen%20Mau"> Cuong Nguyen Mau</a>, <a href="https://publications.waset.org/abstracts/search?q=Duc%20Ninh%20Nguyen"> Duc Ninh Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=The%20Cuong%20Nguyen"> The Cuong Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=The%20Van%20Nguyen"> The Van Nguyen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The National Load Dispatch Centre of Electricity Vietnam (EVNNLDC) and Siemens PTI investigated the stability of the electrical 500/220 kV transportation system of Vietnam. The general scope of the investigations is improving the stability of the Vietnam power system and giving the EVNNLDC staff the capability to decide how to deal with expected stability challenges in the future, which are related to the very fast growth of the system. Rapid system growth leads to a very high demand of power transmission from North to South. This was investigated by stability studies of interconnected power system with neighboring countries. These investigations are performed in close cooperation and coordination with the EVNNLDC project team. This important project includes data collection, measurement, model validation and investigation of relevant stability phenomena as well as training of the EVNNLDC staff. Generally, the power system of Vietnam has good voltage and dynamic stability. The main problems are related to the longitudinal system with more power generation in the North and Center, especially hydro power, and load centers in the South of Vietnam. Faults on the power transmission system from North to South risks the stability of the entire system due to a high power transfer from North to South and high loading of the 500 kV backbone. An additional problem is the weak connection to Cambodia power system which leads to interarea oscillations mode. Therefore, strengthening the power transfer capability by new 500kV lines or HVDC connection and balancing the power generation across the country will solve many challenges. Other countermeasures, such as wide area load shedding, PSS tuning and correct SVC placement will improve and stabilize the power system as well. Primary frequency reserve should be increased. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20power%20transmission%20system%20studies" title="dynamic power transmission system studies">dynamic power transmission system studies</a>, <a href="https://publications.waset.org/abstracts/search?q=blackout%20prevention" title=" blackout prevention"> blackout prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20system%20interconnection" title=" power system interconnection"> power system interconnection</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a> </p> <a href="https://publications.waset.org/abstracts/58895/enhancing-the-stability-of-vietnamese-power-system-from-theory-to-practical" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58895.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">360</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">312</span> Efficient Heuristic Algorithm to Speed Up Graphcut in Gpu for Image Stitching</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tai%20Nguyen">Tai Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Minh%20Bui"> Minh Bui</a>, <a href="https://publications.waset.org/abstracts/search?q=Huong%20Ninh"> Huong Ninh</a>, <a href="https://publications.waset.org/abstracts/search?q=Tu%20Nguyen"> Tu Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Hai%20Tran"> Hai Tran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> GraphCut algorithm has been widely utilized to solve various types of computer vision problems. Its expensive computational cost encouraged many researchers to improve the speed of the algorithm. Recent works proposed schemes that work on parallel computing platforms such as CUDA. However, the problem of low convergence speed prevents the usage of GraphCut for real time applications. In this paper, we propose global suppression heuristic to boost the conver-gence process of the algorithm. A parallel implementation of GraphCut algorithm on CUDA designed for the image stitching problem is introduced. Our method achieves up to 3× time boost on the graph of size 80 × 480 compared to the best sequential GraphCut algorithm while achieving satisfactory stitched images, suitable for panorama applications.

The film condensation model based on mass transfer was used to solve phase change. On the floor, condensation rate was obtained by mass fraction change near the floor. The study investigated effects of inlet velocity, inlet relative humidity and cold floor temperature on the condensation rate. The simulations were done in both 2D and 3D models to show the difference and need for 3D modeling of condensation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20and%20mass%20transfer" title="heat and mass transfer">heat and mass transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=convection" title=" convection"> convection</a>, <a href="https://publications.waset.org/abstracts/search?q=condensation" title=" condensation"> condensation</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20humidity" title=" relative humidity"> relative humidity</a>, <a href="https://publications.waset.org/abstracts/search?q=user-defined%20functions" title=" user-defined functions"> user-defined functions</a> </p> <a href="https://publications.waset.org/abstracts/71123/numeric-modeling-of-condensation-of-water-vapor-from-humid-air-in-a-room" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71123.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">331</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">310</span> Using Priority Order of Basic Features for Circumscribed Masses Detection in Mammograms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Minh%20Dong%20Le">Minh Dong Le</a>, <a href="https://publications.waset.org/abstracts/search?q=Viet%20Dung%20Nguyen"> Viet Dung Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Do%20Huu%20Viet"> Do Huu Viet</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Huu%20Tu"> Nguyen Huu Tu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we present a new method for circumscribed masses detection in mammograms. Our method is evaluated on 23 mammographic images of circumscribed masses and 20 normal mammograms from public Mini-MIAS database. The method is quite sanguine with sensitivity (SE) of 95% with only about 1 false positive per image (FPpI). To achieve above results we carry out a progression following: Firstly, the input images are preprocessed with the aim to enhance key information of circumscribed masses; Next, we calculate and evaluate statistically basic features of abnormal regions on training database; Then, mammograms on testing database are divided into equal blocks which calculated corresponding features. Finally, using priority order of basic features to classify blocks as an abnormal or normal regions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mammograms" title="mammograms">mammograms</a>, <a href="https://publications.waset.org/abstracts/search?q=circumscribed%20masses" title=" circumscribed masses"> circumscribed masses</a>, <a href="https://publications.waset.org/abstracts/search?q=evaluated%20statistically" title=" evaluated statistically"> evaluated statistically</a>, <a href="https://publications.waset.org/abstracts/search?q=priority%20order%20of%20basic%20features" title=" priority order of basic features"> priority order of basic features</a> </p> <a href="https://publications.waset.org/abstracts/48163/using-priority-order-of-basic-features-for-circumscribed-masses-detection-in-mammograms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48163.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">334</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">309</span> The Photon-Drag Effect in Cylindrical Quantum Wire with a Parabolic Potential </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hoang%20Van%20Ngoc">Hoang Van Ngoc</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Thu%20Huong"> Nguyen Thu Huong</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Quang%20Bau"> Nguyen Quang Bau</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Using the quantum kinetic equation for electrons interacting with acoustic phonon, the density of the constant current associated with the drag of charge carriers in cylindrical quantum wire by a linearly polarized electromagnetic wave, a DC electric field and a laser radiation field is calculated.

The criteria of safe separation are researched and investigated for the various standards and handbooks such as MIL-HDBK-1763, MIL-HDBK-244A, AGARD-AG-202 and AGARD-AG-300 to acquire the appropriate and tailored values and limits for the typical applications of external carriages and aircraft fighters. The CFD and 6DOF simulations are extensively used in ANSYS 2023 R1 Software for verification and validation of moving unstructured meshes and solvers by calibrating the position, aerodynamic forces and moments of the existing air-to-ground missile models. The verified CFD and 6DoF simulation separation process is applied and implemented for the investigation of the typical munition separation phenomena and compliance with the tailored requirements of MIL-HDBK-1763. The prediction of munition trajectory parameters under aircraft aerodynamics interference and specified rack unit consideration after munition separation is provided and complied with the tailored requirements to support the safe separation evaluation of improved and newly external store munition before the flight test performed. The proposed process demonstrates the effectiveness and reliability in providing the understanding of the complicated store separation and the reduction of flight test sorties during the improved and new munition development projects by extensively using the CFD and tailoring the existing standards. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=external%20store%20separation" title="external store separation">external store separation</a>, <a href="https://publications.waset.org/abstracts/search?q=MIL-HDBK-1763" title=" MIL-HDBK-1763"> MIL-HDBK-1763</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=moving%20meshes" title=" moving meshes"> moving meshes</a>, <a href="https://publications.waset.org/abstracts/search?q=flight%20test%20data" title=" flight test data"> flight test data</a>, <a href="https://publications.waset.org/abstracts/search?q=munition." title=" munition."> munition.</a> </p> <a href="https://publications.waset.org/abstracts/192199/external-store-safe-separation-evaluation-process-implementing-cfd-and-mil-hdbk-1763" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192199.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">24</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">307</span> Mutation Analysis of the ATP7B Gene in 43 Vietnamese Wilson’s Disease Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huong%20M.%20T.%20Nguyen">Huong M.

Phan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wilson’s disease (WD) is an autosomal recessive disorder of the copper metabolism, which is caused by a mutation in the copper-transporting P-type ATPase (<em>ATP7B</em>). The mechanism of this disease is the failure of hepatic excretion of copper to bile, and leads to copper deposits in the liver and other organs. The <em>ATP7B</em> gene is located on the long arm of chromosome 13 (13q14.3). This study aimed to investigate the gene mutation in the Vietnamese patients with WD, and make a presymptomatic diagnosis for their familial members. Forty-three WD patients and their 65 siblings were identified as having <em>ATP7B</em> gene mutations. Genomic DNA was extracted from peripheral blood samples; 21 exons and exon-intron boundaries of the <em>ATP7B</em> gene were analyzed by direct sequencing. We recognized four mutations ([R723=; H724Tfs*34], V1042Cfs*79, D1027H, and IVS6+3A>G) in the sum of 20 detectable mutations, accounting for 87.2% of the total. Mutation S105* was determined to have a high rate (32.6%) in this study. The hotspot regions of <em>ATP7B</em> were found at exons 2, 16, and 8, and intron 14, in 39.6 %, 11.6 %, 9.3%, and 7 % of patients, respectively. Among nine homozygote/compound heterozygote siblings of the patients with WD, three individuals were determined as asymptomatic by screening mutations of the probands. They would begin treatment after diagnosis. In conclusion, 20 different mutations were detected in 43 WD patients. Of this number, four novel mutations were explored, including [R723=; H724Tfs*34], V1042Cfs*79, D1027H, and IVS6+3A>G. The mutation S105* is the most prevalent and has been considered as a biomarker that can be used in a rapid detection assay for diagnosis of WD patients. Exons 2, 8, and 16, and intron 14 should be screened initially for WD patients in Vietnam. Based on risk profile for WD, genetic testing for presymptomatic patients is also useful in diagnosis and treatment. <p class="card-text"><strong>Keywords:</strong> <a
