the effect of belt stiffness on the performance of the CVT unit, such as the required pulley thrust force and the ratio coverage. The CVT unit consists of the V-grooved pulleys and the rubber CVT belt. The width of the driving pulley groove was controlled by the stepper motor, while that of the driven pulley was controlled by the hydraulic pressure. The generated mechanical power on the motor was transmitted from the driving axis to the driven axis through the CVT unit. The rotational speed and the transmitting torque of both axes were measured by the tachometers and the torque meters attached with these axes, respectively. The transmitted, mechanical power was absorbed by the magnetic powder brake. The thrust force acting on both pulleys and the force between both shafts were measured by the load cell. The back face profile of the rubber CVT belt along with width direction was measured by the 2-dimensional laser displacement meter. This paper found that when the stiffness of the rubber CVT belt in the belt width direction was reduced, the thrust force required for shifting was reduced. Moreover, when the stiffness of the rubber CVT belt in the belt width direction was reduced, the ratio coverage of the CVT unit was reduced. Due to the decrement of stiffness in belt width direction, the excessive concave deformation of belt in pulley groove was confirmed. Because of this excessive concave deformation, apparent wrapping radius of belt would have been reduced. Proposed model could be effectively estimated the difference of ratio coverage due to concave deformation. The proposed model could also be utilized for designing the rubber CVT belt with optimal bending stiffness in width direction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CVT" title="CVT">CVT</a>, <a href="https://publications.waset.org/abstracts/search?q=countinuously%20variable%20transmission" title=" countinuously variable transmission"> countinuously variable transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=rubber" title=" rubber"> rubber</a>, <a href="https://publications.waset.org/abstracts/search?q=belt%20stiffness" title=" belt stiffness"> belt stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission" title=" transmission"> transmission</a> </p> <a href="https://publications.waset.org/abstracts/146641/study-on-shifting-properties-of-cvt-rubber-v-belt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146641.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">142</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">35</span> The Framework of System Safety for Multi Human-in-The-Loop System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hideyuki%20Shintani">Hideyuki Shintani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ichiro%20Koshijima"> Ichiro Koshijima</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Cyber Physical System (CPS), if there are a large number of persons in the process, a role of person in CPS might be different comparing with the one-man system.

The cause of such explosions is thought to be the reaction of metallic aluminum contained in the ash with water used to cool the ash and prevent scattering, resulting in the generation of hydrogen. Given this background, conveyors and other equipment have been damaged by explosions, which has hindered the stable operation of incineration plants. In addition, workers may be injured by equipment explosions, creating an unsafe situation. To remedy these problems, it is necessary to devise a way to prevent hydrogen explosions from occurring. To overcome this problem, we conducted a hydrogen generation reaction experiment using simulated incinerator ash powder containing aluminum, calcium oxide, and water and confirmed that conditions exist to stop the hydrogen generation reaction. The results of this research may contribute to the suppression of hydrogen explosions at incineration plants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=waste%20incinerated%20ash" title="waste incinerated ash">waste incinerated ash</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminum" title=" aluminum"> aluminum</a>, <a href="https://publications.waset.org/abstracts/search?q=water" title=" water"> water</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen" title=" hydrogen"> hydrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=suppression%20of%20hydrogen%20generation" title=" suppression of hydrogen generation"> suppression of hydrogen generation</a>, <a href="https://publications.waset.org/abstracts/search?q=incineration%20plant" title=" incineration plant"> incineration plant</a> </p> <a href="https://publications.waset.org/abstracts/186080/study-on-the-suppression-of-hydrogen-generation-by-aluminum-containing-waste-incineration-ash-and-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186080.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">28</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">32</span> A Qualitative Study on Overcoming Problems and Limitations of Telepsychological Support (Online Counseling): Through Interviews with Practitioners</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Toshiki%20Ito">Toshiki Ito</a>, <a href="https://publications.waset.org/abstracts/search?q=Takahiro%20Yamane"> Takahiro Yamane</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuki%20Adachi"> Yuki Adachi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoshiko%20Kato"> Yoshiko Kato</a>, <a href="https://publications.waset.org/abstracts/search?q=Eiji%20Tsuda"> Eiji Tsuda</a>, <a href="https://publications.waset.org/abstracts/search?q=Kousaku%20Nagasaka"> Kousaku Nagasaka</a>, <a href="https://publications.waset.org/abstracts/search?q=Keigo%20Yoshida">Keigo Yoshida</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoshiko%20Kawasaki"> Yoshiko Kawasaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Naoki%20Aizawa"> Naoki Aizawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyouhei%20Nishi"> Kyouhei Nishi</a>, <a href="https://publications.waset.org/abstracts/search?q=Tetsuko%20Kato"> Tetsuko Kato</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The epidemic of the coronavirus (COVID-19), first reported in Wuhan at the end of 2019, has drastically changed our daily lives. Under these circumstances, counseling, which provides psychological support to people, was also greatly affected. The structure of counseling, which had generally been implicitly common practice to be conducted in person, was greatly shaken. The author wondered how counseling can be conducted in situations where it is impossible to meet face-to-face. This is where telepsychological support (online counseling) came into use. The authors found that there were the following problems in telepsychological support: (1) anxiety about whether the communication is appropriate, (2) difficulty in understanding the client's situation and condition, (3) inability to perceive what was normally perceived in person, (4) difficulty in adjusting to severely ill clients, (5) difficulty in dealing with emergency situations, etc. In this study, we interviewed psychologists who had been accustomed to telepsychological support for more than two years after the Corona disaster began to clarify how they had or had not overcome the problems of telepsychological support identified in the above studies. We also aim to consider the unique possibilities of how telepsychological support, a new technique of psychological support, can be implemented to provide more effective and meaningful support in society after the end of the Corona disaster (post-Corona society). Thirteen psychologists who are currently providing telepsychological support in the Corona Disaster will be interviewed, and semi-structured interviews will be conducted for one hour per person. In order to empirically examine how the problems in telepsychological support had been overcome or not through the interview survey, the authors asked (1) how they overcame their anxiety about whether they were able to communicate appropriately, (2) how they devised ways to overcome it, (3) how they overcame the difficulty in adapting to heavy clients in terms of the level of the disease, (4) how they overcame the difficulty in dealing with emergency situations. The interviews were analyzed using Thematic Analysis, a qualitative analysis method commonly used in qualitative research overseas. The authors found that some devices and perspectives were newly discovered as a result of two years of practice of telepsychological support and that psychologists in this study considered face-to-face interviews and telepsychological support to be separate and were flexible enough to use them when available and to move to face-to-face interviews when not appropriate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=telepsychology" title="telepsychology">telepsychology</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title=" COVID-19"> COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=Corona" title=" Corona"> Corona</a>, <a href="https://publications.waset.org/abstracts/search?q=psychologist" title=" psychologist"> psychologist</a> </p> <a href="https://publications.waset.org/abstracts/165634/a-qualitative-study-on-overcoming-problems-and-limitations-of-telepsychological-support-online-counseling-through-interviews-with-practitioners" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165634.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">107</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">31</span> Fabrication of Hollow Germanium Spheres by Dropping Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kunal%20D.%20Bhagat">Kunal D.

The germanium was first melted at around 1273 K and then exuded from a coaxial nozzle into an inert atmosphere by argon gas supplied to the inner nozzle. The falling spheres were cooled by water spray and collected in a bucket. The spheres had a horn type of structure on the outer surface, which might be caused by volume expansion induced by the density difference between solid and gas phase. The frequency of the sphere formation was determined from the videos to be about 133 Hz. The outer diameter varied in the range of 1.3 to 1.8 mm with a wall thickness in the range of 0.2 to 0.5 mm. Solid silicon spheres are used for spherical silicon solar cells (S₃CS), which have various attractive features. Hollow S₃CS promise substantially higher energy conversion efficiency if their wall thickness can be kept to 0.1–0.2 mm and the inner surface can be passivated. Our production of hollow germanium spheres is a significant step towards the production of hollow S₃CS with, we hope, higher efficiency and lower material cost than solid S₃CS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hollow%20spheres" title="hollow spheres">hollow spheres</a>, <a href="https://publications.waset.org/abstracts/search?q=semiconductor" title=" semiconductor"> semiconductor</a>, <a href="https://publications.waset.org/abstracts/search?q=compound%20jet" title=" compound jet"> compound jet</a>, <a href="https://publications.waset.org/abstracts/search?q=dropping%20method" title=" dropping method"> dropping method</a> </p> <a href="https://publications.waset.org/abstracts/133344/fabrication-of-hollow-germanium-spheres-by-dropping-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133344.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">208</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">30</span> The Study about the New Monitoring System of Signal Equipment of Railways Using Radio Communication</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masahiko%20Suzuki">Masahiko Suzuki</a>, <a href="https://publications.waset.org/abstracts/search?q=Takashi%20Kato"> Takashi Kato </a>, <a href="https://publications.waset.org/abstracts/search?q=Masahiro%20Kobayashi"> Masahiro Kobayashi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In our company, the monitoring system for signal equipment has already implemented.

The composition of the violet Sr–Al–O:Eu2+ phosphor particles was determined from various Sr–Al–O:Eu2+ phosphors by their emission properties’ dependence on temperature. The highly crystalline SrAl12O19:Eu2+ emission phases were confirmed by their crystallite sizes and the activation energies for the 4f5d–8S7/2 transition of the Eu2+ ion.

This paper proposes a method to estimate positions of a mobile robot using an omnidirectional camera on the robot. Landmarks for points of references are set up on a field where the robot works. The omnidirectional camera which can obtain 360 [deg] around images takes photographs of these landmarks. The positions of the robots are estimated from directions of these landmarks that are extracted from the images by image processing. This method can obtain the robot positions without accumulative position errors. Accuracy of the estimated robot positions by the proposed method are evaluated through some experiments. The results show that it can obtain the positions with small standard deviations. Therefore the method has possibilities of more accurate localization by tuning of appropriate offset parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mobile%20robots" title="mobile robots">mobile robots</a>, <a href="https://publications.waset.org/abstracts/search?q=localization" title=" localization"> localization</a>, <a href="https://publications.waset.org/abstracts/search?q=omnidirectional%20camera" title=" omnidirectional camera"> omnidirectional camera</a>, <a href="https://publications.waset.org/abstracts/search?q=estimating%20positions" title=" estimating positions"> estimating positions</a> </p> <a href="https://publications.waset.org/abstracts/11803/localization-of-mobile-robots-with-omnidirectional-cameras" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11803.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">26</span> Particle Concentration Distribution under Idling Conditions in a Residential Underground Garage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yu%20Zhao">Yu Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Shinsuke%20Kato"> Shinsuke Kato</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianing%20Zhao"> Jianing Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Particles exhausted from cars have an adverse impacts on human health.

The enhancement of particle dispersion in the vertical direction due to the increase of cars with engine running is much stronger than that in the car exhaust direction. Particle dispersion from each pair of adjacent cars has little influence on each other in the study.

It is essential to prevent troubles in healthcare processes for healthcare safety. Trouble prevention is based on trouble prediction using accumulated knowledge on processes, troubles, and countermeasures. However, information on troubles has not been accumulated in hospitals in the appropriate structure, and it has not been utilized effectively to prevent troubles. In the previous study, though a detailed knowledge acquisition process for trouble prediction was proposed, the knowledgebase for countermeasures was not involved. In this paper, we aim to propose the structure of the knowledgebase for countermeasures in the knowledge acquisition process for trouble prediction in healthcare process. We first design the structure of countermeasures and propose the knowledge representation form on countermeasures. Then, we evaluate the validity of the proposal, by applying it into an actual hospital. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=trouble%20prevention" title="trouble prevention">trouble prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20structure" title=" knowledge structure"> knowledge structure</a>, <a href="https://publications.waset.org/abstracts/search?q=structured%20knowledge" title=" structured knowledge"> structured knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=reusable%20knowledge" title=" reusable knowledge"> reusable knowledge</a> </p> <a href="https://publications.waset.org/abstracts/37281/development-of-the-structure-of-the-knowledgebase-for-countermeasures-in-the-knowledge-acquisition-process-for-trouble-prediction-in-healthcare-processes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37281.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">367</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">24</span> Building Capacity and Personnel Flow Modeling for Operating amid COVID-19</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Fernandes">Samuel Fernandes</a>, <a href="https://publications.waset.org/abstracts/search?q=Dylan%20Kato"> Dylan Kato</a>, <a href="https://publications.waset.org/abstracts/search?q=Emin%20Burak%20Onat"> Emin Burak Onat</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Keyantuo"> Patrick Keyantuo</a>, <a href="https://publications.waset.org/abstracts/search?q=Raja%20%20Sengupta"> Raja Sengupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Amine%20Bouzaghrane"> Amine Bouzaghrane</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The COVID-19 pandemic has spread across the United States, forcing cities to impose stay-at-home and shelter-in-place orders.

In this paper we propose a methodology for capacity and flow modeling of personnel within buildings to safely operate under COVID-19 guidelines. We model personnel flow within buildings by network flows with queuing constraints. We study maximum flow, minimum cost, and minimax objectives. We compare our network flow approach with a simulation model through a case study and present the results.

Its usefulness has been confirmed by simulation experiments specifying rules in advance, and by comparison with conventional methods. However, scope for future development remains before STRIM can be applied to the analysis of real-world data sets. The first requirement is to determine the size of the dataset needed for inducting true rules, since finding statistically significant rules is the core of the method. The second is to examine the capacity of rule induction from datasets with contaminated attribute values created by missing data and noise, since real-world datasets usually contain such contaminated data. This paper examines the first problem theoretically, in connection with the rule length. The second problem is then examined in a simulation experiment, utilizing the critical size of dataset derived from the first step. The experimental results show that STRIM is highly robust in the analysis of datasets with contaminated attribute values, and hence is applicable to realworld data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rule%20induction" title="rule induction">rule induction</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20table" title=" decision table"> decision table</a>, <a href="https://publications.waset.org/abstracts/search?q=missing%20data" title=" missing data"> missing data</a>, <a href="https://publications.waset.org/abstracts/search?q=noise" title=" noise"> noise</a> </p> <a href="https://publications.waset.org/abstracts/22621/studies-of-rule-induction-by-strim-from-the-decision-table-with-contaminated-attribute-values-from-missing-data-and-noise-in-the-case-of-critical-dataset-size" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22621.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">396</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Disaster Mitigation from an Analysis of a Condemned Building Erected over Collapsible Clay Soil in Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Jesus%20Kato%20Avila">Marcelo Jesus Kato Avila</a>, <a href="https://publications.waset.org/abstracts/search?q=Joao%20Da%20Costa%20Pantoja"> Joao Da Costa Pantoja</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Differential settlement of foundations is a serious pathology in buildings that put at risk lives and property. A common reason for the occurrence of this specific pathology in central Brazil is the presence of collapsible clay, a typical soil in the region. In this study, the foundation of a condemned building erected above this soil is analyzed. The aim is to prevent problems in new constructions, to predict which buildings may be subjected to damages, and to make possible a more precise treatment in less advanced differential settlements observed in the buildings of the vicinity, which includes a hospital, a Military School, an indoor sporting arena, the Police Academy, and the Military Police Headquarters. The methodology consists of visual inspection, photographic report of the main pathologies, analysis of the existing foundations, determination of the soil properties, the study of the cracking level and assessment of structural failure risk of the building. The findings show that the presence of water weaken the soil structure on which the foundation rest, being the main cause of the pathologic settlement, indicating that even in a one store building it was necessary to consider deeper digging, other categories of foundations, and more elaborated and detailed foundation plans when the soil presents this behavior. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building%20cracks" title="building cracks">building cracks</a>, <a href="https://publications.waset.org/abstracts/search?q=collapsible%20clay" title=" collapsible clay"> collapsible clay</a>, <a href="https://publications.waset.org/abstracts/search?q=differential%20settlement" title=" differential settlement"> differential settlement</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20failure%20risk" title=" structural failure risk"> structural failure risk</a> </p> <a href="https://publications.waset.org/abstracts/73845/disaster-mitigation-from-an-analysis-of-a-condemned-building-erected-over-collapsible-clay-soil-in-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73845.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">255</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">21</span> A Nucleic Acid Extraction Method for High-Viscosity Floricultural Samples</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harunori%20Kawabe">Harunori Kawabe</a>, <a href="https://publications.waset.org/abstracts/search?q=Hideyuki%20Aoshima"> Hideyuki Aoshima</a>, <a href="https://publications.waset.org/abstracts/search?q=Koji%20Murakami"> Koji Murakami</a>, <a href="https://publications.waset.org/abstracts/search?q=Minoru%20Kawakami"> Minoru Kawakami</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuka%20Nakano"> Yuka Nakano</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20D.%20Ordinario"> David D.

As a prerequisite for gene editing, the gene sequence of the target plant must first be identified. This necessitates the genetic analysis of plants with unknown gene sequences, the extraction of RNA, and comprehensive expression analysis. Consequently, a technology capable of consistently and effectively extracting high-purity DNA and RNA from plants is of paramount importance. Although model plants, such as Arabidopsis and tobacco, have established methods for DNA and RNA extraction, floricultural species such as roses present unique challenges. Different techniques to extract DNA and RNA from various floricultural species were investigated. Upon sampling and grinding the petals of several floricultural species, it was observed that nucleic acid extraction from the ground petal solutions of low viscosity was straightforward; solutions of high viscosity presented a significant challenge. It is postulated that the presence of substantial quantities of polysaccharides and polyphenols in the plant tissue was responsible for the inhibition of nucleic acid extraction. Consequently, attempts were made to extract high-purity DNA and RNA by improving the CTAB method and combining it with commercially available nucleic acid extraction kits. The quality of the total extracted DNA and RNA was evaluated using standard methods. Finally, the effectiveness of the extraction method was assessed by determining whether it was possible to create a library that could be applied as a suitable template for a next-generation sequencer. In conclusion, a method was developed for consistent and accurate nucleic acid extraction from high-viscosity floricultural samples. These results demonstrate improved techniques for DNA and RNA extraction from flowers, help facilitate gene editing of floricultural species and expand the boundaries of research and commercial opportunities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=floriculture" title="floriculture">floriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=gene%20editing" title=" gene editing"> gene editing</a>, <a href="https://publications.waset.org/abstracts/search?q=next-generation%20sequencing" title=" next-generation sequencing"> next-generation sequencing</a>, <a href="https://publications.waset.org/abstracts/search?q=nucleic%20acid%20extraction" title=" nucleic acid extraction"> nucleic acid extraction</a> </p> <a href="https://publications.waset.org/abstracts/191049/a-nucleic-acid-extraction-method-for-high-viscosity-floricultural-samples" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191049.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">29</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">20</span> Optimal Selling Prices for Small Sized Poultry Farmers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hidefumi%20Kawakatsu">Hidefumi Kawakatsu</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong%20Li"> Dong Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Kosuke%20Kato"> Kosuke Kato</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Japan, meat-type chickens are mainly classified into three categories: (1) Broilers, (2) Branded chickens, and (3) <em>Jidori </em>(Free-range local traditional pedigree chickens). The Jidori chickens are certified by the Japanese Ministry of Agriculture, whilst, for the Branded chickens, there is no regulation with respect to their breed (genotype) or methods for rearing them. It is, therefore, relatively easy for poultry farmers to introduce Branded than Jidori chickens. The Branded chickens are normally fed a low-calorie diet with ingredients such as herbs, which lengthens their breeding period (compared with that of the Broilers) and increases their market value. In the field of inventory management, fast-growing animals such as broilers are categorised as ameliorating items. To the best of our knowledge, there are no previous studies that have explicitly considered smaller sized poultry farmers with limited breeding areas. This study develops an inventory model for a small sized poultry farmer that produces both the Broilers (Product 1) and the Branded chickens (Product 2) with different amelioration rates. The poultry farmer’s total profit per unit of time is formulated as a function of selling prices by using a price-dependent demand function. The existence of a unique optimal selling price for each product, which maximises the total profit, established. It has also been confirmed through numerical examples that, when the breeding area is fixed, the total profit could increase if the poultry farmer reduced the product quantity of Product 1 to introduce Product 2. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amelioration" title="amelioration">amelioration</a>, <a href="https://publications.waset.org/abstracts/search?q=deterioration" title=" deterioration"> deterioration</a>, <a href="https://publications.waset.org/abstracts/search?q=small%20sized%20poultry%20farmers" title=" small sized poultry farmers"> small sized poultry farmers</a>, <a href="https://publications.waset.org/abstracts/search?q=optimal%20price" title=" optimal price"> optimal price</a> </p> <a href="https://publications.waset.org/abstracts/77385/optimal-selling-prices-for-small-sized-poultry-farmers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77385.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">214</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">19</span> Effect of Burdock Root Extract Concentration on Physiochemical Property of Coated Jasmine Rice by Using Top-Spay Fluidized Bed Coating Technique </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Donludee%20Jaisut">Donludee Jaisut</a>, <a href="https://publications.waset.org/abstracts/search?q=Norihisa%20Kato"> Norihisa Kato</a>, <a href="https://publications.waset.org/abstracts/search?q=Thanutchaporn%20Kumrungsee"> Thanutchaporn Kumrungsee</a>, <a href="https://publications.waset.org/abstracts/search?q=Kiyoshi%20Kawai"> Kiyoshi Kawai</a>, <a href="https://publications.waset.org/abstracts/search?q=Somkiat%20Prachayawarakorn"> Somkiat Prachayawarakorn</a>, <a href="https://publications.waset.org/abstracts/search?q=Patchalee%20Tungtrakul"> Patchalee Tungtrakul </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Jasmine Rice is a principle food of Thai people. However, glycemic index of jasmine rice is in high level, risk of type II diabetes after consuming. Burdock root is a good source of non-starch polysaccharides such as inulin. Inulin acts as prebiotic and helps reduce blood-sugar level. The purpose of this research was to reduce digestion rate of jasmine rice by coating burdock root extract on rice surface, using top-spay fluidized bed coating technique. Coating experiments were performed by spraying burdock root solution onto Jasmine rice kernels (Khao Dawk Mali-105; KDML), which had an initial moisture content of 11.6% wet basis, suspended in the fluidized bed. The experimental conditions were: solution spray rates of 31.7 mL/min, atomization pressure of 1.5 bar, spray time of 10 min, time of drying after spraying of 30 s, superficial air velocity of 3.2 m/s and drying temperatures of 60°C. The coated rice quality was evaluated in terms of the moisture content, texture, whiteness and digestion rate. The results showed that initial and final moisture contents of samples were the same in concentration 8% (v/v) and 10% (v/v). The texture was insignificantly changed from that of uncoated sample. The whiteness values were varied on concentration of burdock root extract. Coated samples were slower digested. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=burdock%20root" title="burdock root">burdock root</a>, <a href="https://publications.waset.org/abstracts/search?q=digestion" title=" digestion"> digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=drying" title=" drying"> drying</a>, <a href="https://publications.waset.org/abstracts/search?q=rice" title=" rice"> rice</a> </p> <a href="https://publications.waset.org/abstracts/60231/effect-of-burdock-root-extract-concentration-on-physiochemical-property-of-coated-jasmine-rice-by-using-top-spay-fluidized-bed-coating-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60231.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">293</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">18</span> Influence of Peripheral Vision Restrictions on the Walking Trajectory When Texting While Walking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Macky%20Kato">Macky Kato</a>, <a href="https://publications.waset.org/abstracts/search?q=Takeshi%20Sato"> Takeshi Sato</a>, <a href="https://publications.waset.org/abstracts/search?q=Mizuki%20Nakajima"> Mizuki Nakajima</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One major problem related to the use of smartphones is texting while simultaneously engaging in other things, resulting in serious road accidents. Apart from texting while driving being one of the most dangerous behaviors, texting while walking is also dangerous because it narrows the pedestrians’ field of vision. However, many of pedestrian text while walking very habitually. Smartphone users often overlook the potential harm associated with this behavior even while crossing roads. The successful texting while walking make them think that they are safe. The purpose of this study is to reveal of the influence of peripheral vision to the stability of walking trajectory with texting while walking. In total, 9 healthy male university students participated in the experiment. Their mean age was 21.4 years, and standard deviation was 0.7 years. They attempted to walk 10 m in three conditions. First one is the control (CTR) condition, with no phone and no restriction. The second one is the texting while walking (TWG) with no restrictions. The third one is restriction condition (PRS), with phone restricted by experimental peripheral goggles. The horizontal distances (HDS) and directions are measured as the scale of horizontal stability. The longitudinal distances (LDS) between the footprints were measured as the scale of the walking rhythm. The results showed that the HDS of the footprints from the straight line increased as the participants walked in the TWG and PRS conditions. In the PRS condition, this tendency was particularly remarkable. In addition, the LDS between the footprints decreased in the order of the CTR, TWG, and PRS conditions. The ANOVA results showed significant differences in the three conditions with respect to HDS. The differences among these conditions showed that the narrowing of the Pedestrian's vision because of smartphone use influences the walking trajectory and rhythm. It can be said that the pedestrians seem to use their peripheral vision marginally on texting while walking. Therefore, we concluded that the texting while walking narrows the peripheral vision so danger to increase the risk of the accidents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=peripheral%20vision" title="peripheral vision">peripheral vision</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a>, <a href="https://publications.waset.org/abstracts/search?q=texting%20while%20walking" title=" texting while walking"> texting while walking</a>, <a href="https://publications.waset.org/abstracts/search?q=walking%20trajectory" title=" walking trajectory"> walking trajectory</a> </p> <a href="https://publications.waset.org/abstracts/77017/influence-of-peripheral-vision-restrictions-on-the-walking-trajectory-when-texting-while-walking" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77017.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">17</span> Effect of Pole Weight on Nordic Walking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Takeshi%20Sato">Takeshi Sato</a>, <a href="https://publications.waset.org/abstracts/search?q=Mizuki%20Nakajima"> Mizuki Nakajima</a>, <a href="https://publications.waset.org/abstracts/search?q=Macky%20Kato"> Macky Kato</a>, <a href="https://publications.waset.org/abstracts/search?q=Shoji%20Igawa"> Shoji Igawa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of study was to investigate the effect of varying pole weights on energy expenditure, upper limb and lower limb muscle activity as Electromyogram during Nordic walking (NW). Four healthy men [age = 22.5 (±1.0) years, body mass = 61.4 (±3.6) kg, height = 170.3 (±4.3) cm] and three healthy women [age = 22.7 (±2.9) years, body mass = 53.0 (±1.7) kg, height = 156.7 (±4.5) cm] participated in the experiments after informed consent. Seven healthy subjects were tested on the treadmill, walking, walking (W) with Nordic Poles (NW) and walking with 1kg weight Nordic Poles (NW+1). Walking speed was 6 km per hours in all trials. Eight EMG activities were recorded by bipolar surface methods in biceps brachii, triceps brachii, trapezius, deltoideus, tibialis anterior, medial gastrocnemius, rectus femoris and biceps femoris muscles. And heart rate (HR), oxygen uptake (VO<sub>2</sub>), and rate of perceived exertion (RPE) were measured. The level of significance was set at a = 0.05, with p < 0.05 regarded as statistically significant. Our results confirmed that use of NW poles increased HR at a given upper arm muscle activity but decreased lower limb EMGs in comparison with W. Moreover NW was able to increase more step lengths with hip joint extension during NW rather than W. Also, EMG revealed higher activation of upper limb for almost all NW and 1kgNW tests plus added masses compared to W (p < 0.05). Therefore, it was thought either of NW and 1kgNW were to have benefit as a physical exercise for safe, feasible, and readily training for a wide range of aged people in the quality of daily life. However, there was no significant effected in leg muscles activity by using 1kgNW except for upper arm muscle activity during Nordic pole walking. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nordic%20walking" title="Nordic walking">Nordic walking</a>, <a href="https://publications.waset.org/abstracts/search?q=electromyogram" title=" electromyogram"> electromyogram</a>, <a href="https://publications.waset.org/abstracts/search?q=heart%20rate" title=" heart rate"> heart rate</a>, <a href="https://publications.waset.org/abstracts/search?q=RPE" title=" RPE"> RPE</a> </p> <a href="https://publications.waset.org/abstracts/77579/effect-of-pole-weight-on-nordic-walking" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77579.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">239</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Effect of Co-Infection With Intestinal Parasites on COVID-19 Severity: A Prospective Observational Cohort Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Teklay%20Gebrecherkos">Teklay Gebrecherkos</a>, <a href="https://publications.waset.org/abstracts/search?q=Dawit%20Wolday"> Dawit Wolday</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhamud%20Abdulkader"> Muhamud Abdulkader</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: COVID-19 symptomatology in Africa appears significantly less serious than in the industrialized world. Our hypothesis for this phenomenon, being a different, more activated immune system due to parasite infections contributes to reduced COVID-19 outcome. We investigated this hypothesis in an endemic area in sub sub-saharan Africa. Methods: Ethiopian COVID-19 patients were enrolled and screened for intestinal parasites, between July 2020 and March 2021. The primary outcome was the proportion of patients with severe COVID-19. SARS-CoV-2 infection was confirmed by RT-PCR on samples obtained from nasopharyngeal swabs, while direct microscopic examination, modified Ritchie concentration, and Kato-Katz methods were used to identify parasites and ova from a fresh stool sample. Ordinal logistic regression models were used to estimate the association between parasite infection and COVID-19 severity. Models were adjusted for sex, age, residence, education level, occupation, body mass index, and comorbidities. Data were analyzed using STATA version 14. P-value <0.05 was considered statistically significant. Results: A total of 751 SARS-CoV-2 infected patients were enrolled, of whom 284 (37•8%) had an intestinal parasitic infection. Only 27/255 (10•6%) severe COVID-19 patients were co-infected with intestinal parasites, while 257/496 (51•8%) non-severe COVID-19 patients appeared parasite positive (p<0.0001). Patients co-infected with parasites had lower odds of developing severe COVID-19, with an adjusted odds ratio (AOR) of 0•14 (95% CI 0•09–0•24; p<0•0001) for all parasites, AOR 0•20 ([95% CI 0•11–0•38]; p<0•0001) for protozoa, and AOR 0•13 ([95% CI 0•07–0•26]; p<0•0001) for helminths. When stratified by species, co-infection with Entamoeba spp., Hymenolopis nana, and Schistosoma mansoni implied a lower probability of developing severe COVID-19. There were 11 deaths (1•5%), and all were among patients without parasites (p=0•009). Conclusions: Parasite co-infection is associated with a reduced risk of severe COVID-19 in African patients. Parasite-driven immunomodulatory responses may mute hyper-inflammation associated with severe COVID-19. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title="COVID-19">COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=SARS-COV-2" title=" SARS-COV-2"> SARS-COV-2</a>, <a href="https://publications.waset.org/abstracts/search?q=intestinal%20parasite" title=" intestinal parasite"> intestinal parasite</a>, <a href="https://publications.waset.org/abstracts/search?q=RT-PCR" title=" RT-PCR"> RT-PCR</a>, <a href="https://publications.waset.org/abstracts/search?q=co-infection" title=" co-infection"> co-infection</a> </p> <a href="https://publications.waset.org/abstracts/175844/effect-of-co-infection-with-intestinal-parasites-on-covid-19-severity-a-prospective-observational-cohort-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175844.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">60</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">15</span> Anti-Parasite Targeting with Amino Acid-Capped Nanoparticles Modulates Multiple Cellular Processes in Host</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oluyomi%20Stephen%20Adeyemi">Oluyomi Stephen Adeyemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kentaro%20Kato"> Kentaro Kato</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Toxoplasma gondii is the etiological agent of toxoplasmosis, a common parasitic disease capable of infecting a range of hosts, including nearly one-third of the human population. Current treatment options for toxoplasmosis patients are limited. In consequence, toxoplasmosis represents a large global burden that is further enhanced by the shortcomings of the current therapeutic options. These factors underscore the need for better anti-T. gondii agents and/or new treatment approach. In the present study, we sought to find out whether preparing and capping nanoparticles (NPs) in amino acids, would enhance specificity toward the parasite versus the host cell. The selection of amino acids was premised on the fact that T. gondii is auxotrophic for some amino acids. The amino acid-nanoparticles (amino-NPs) were synthesized, purified and characterized following established protocols. Next, we tested to determine the anti-T. gondii activity of the amino-NPs using in vitro experimental model of infection. Overall, our data show evidence that supports enhanced and excellent selective action against the parasite versus the host cells by amino-NPs. The findings are promising and provide additional support that warrants exploring the prospects of NPs as alternative anti-parasite agents. In addition, the anti-parasite action by amino-NPs indicates that nutritional requirement of parasite may represent a viable target in the development of better alternative anti-parasite agents. Furthermore, data suggest the anti-parasite mechanism of the amino-NPs involves multiple cellular processes including the production of reactive oxygen species (ROS), modulation of hypoxia-inducing factor-1 alpha (HIF-1α) as well as the activation of kynurenine pathway. Taken together, findings highlight further, the prospects of NPs as alternative source of anti-parasite agents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drug%20discovery" title="drug discovery">drug discovery</a>, <a href="https://publications.waset.org/abstracts/search?q=infectious%20diseases" title=" infectious diseases"> infectious diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=mode%20of%20action" title=" mode of action"> mode of action</a>, <a href="https://publications.waset.org/abstracts/search?q=nanomedicine" title=" nanomedicine"> nanomedicine</a> </p> <a href="https://publications.waset.org/abstracts/99325/anti-parasite-targeting-with-amino-acid-capped-nanoparticles-modulates-multiple-cellular-processes-in-host" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99325.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">112</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">14</span> Schistosoma mansoni Infection and Risk Factors among Fishermen at Lake Hawassa, Southern Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tadesse%20Menjetta">Tadesse Menjetta</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Dana"> Daniel Dana</a>, <a href="https://publications.waset.org/abstracts/search?q=Serkadis%20Debalke"> Serkadis Debalke</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Schistosomiasis/Bilharziasis is one of the neglected tropical parasitic diseases caused by different species of genus Schistosoma. Among the species, S. mansoni (causative agents of intestinal schistosomiasis) is one of the causes of severe intestinal parasitic infections with high public and medical importance in Ethiopia. There is a scarcity of information about the status of S. mansoni infection among the fisherman in our study area and in the country at large. Therefore, this study was designed to determine the prevalence and risk factors of S.mansoni infection among fishermen at Lake Hawassa, southern Ethiopia. A cross-sectional study was conducted among the fishermen from April to June 2013 in Hawassa, Southern Ethiopia. A total of 243 fishermen were included by systematic sampling from the lists of the fishermen members in the registration book of fishermen associations in the Hawassa Town. Data on socio-demographic features and risk factors were collected by using semi-structured questionnaires. Stool samples were collected and processed using Kato-Katz thick smear techniques and examined between 30- 40 minute for hookworm and after 24 hours for S. mansoni and other soil-transmitted helminths (STHs). The overall prevalence of S.mansoni among the fishermen was 29.21% (71/243), and the mean intensity of infection was 158.88 egg per gram (EPG). The prevalence of intestinal helminths including S. mansoni was 69.54% (169/243). Moreover, the prevalence of soil-transmitted helminths (STHs) was 40.74% (99/243), 35.80% (87/243) and 5.76% (14/243) for A. lumbricoides, T. trichiura and hookworm species, respectively. Almost similar prevalence of S.mansoni, 31.82%, 31.75%, 31.94% were recorded in age groups of 15-19, 20-24 and 25-29 years, respectively. Fishermen who are swimming always were 2.92 times [95% CI: 1.554, 5.502] more likely to acquire S. mansoni infection than other water contacting habit of the study participants. The results of the current investigation indicated the moderate endemicity of S. mansoni among the fishermen at Lake Hawassa, southern Ethiopia. Fishermen could be the potential risk group for S. mansoni infection and might be responsible for the transmission of S. mansoni to other segments of the communities. Since the high prevalence of STH was recorded among the fishermen, integrated prevention and control strategies from different sectors might be important to tackle the problem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20mansoni" title="S. mansoni">S. mansoni</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20transmitted%20helminths" title=" soil transmitted helminths"> soil transmitted helminths</a>, <a href="https://publications.waset.org/abstracts/search?q=fishermen" title=" fishermen"> fishermen</a>, <a href="https://publications.waset.org/abstracts/search?q=Lake%20Hawassa" title=" Lake Hawassa"> Lake Hawassa</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a> </p> <a href="https://publications.waset.org/abstracts/102802/schistosoma-mansoni-infection-and-risk-factors-among-fishermen-at-lake-hawassa-southern-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102802.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">13</span> Occurrence of Broiler Chicken Breast White Striping Meat in Brazilian Commercial Plant </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Talita%20Kato">Talita Kato</a>, <a href="https://publications.waset.org/abstracts/search?q=Moises%20Grespan"> Moises Grespan</a>, <a href="https://publications.waset.org/abstracts/search?q=Elza%20I.%20Ida"> Elza I.

It is characterized by the appearance of varying degrees of white striations on the Pectoralis major muscle surface following the direction of the muscle fiber. The etiology of this myopathy is still unknown, however it is suggested to be associated with increased weight gain rate and age of the bird, attributing the phenomenon to the genetically bird’s selection for efficiently higher meat production. The aim of this study was to evaluate the occurrence of Pectoralis major WS in a commercial plant in southern Brazil and its chemical characterization. The breast meat samples (n=660) from birds of 47 days of age, were classified as: Normal NG (no apparent white striations), Moderate MG (when the fillets present thin lines <1 mm) and Severe SG (white striations present ˃1 mm thick covering a large part of the fillet surface). Thirty samples (n = 10 for each level of severity) were analyzed for pH, color (L*, a*, b*), proximate chemical composition (moisture, protein, ash and lipids contents) and hydroxyproline in order to determine the collagen content. The results revealed the occurrence for NG group was 16.97%, 51.67% for MG group and 31.36% for SG group. Although the total protein content did not differ significantly, the collagen index was 42% higher in favor to SG in relation to NG. Also the lipid fraction was 27% higher for SG group. The NG presented the lowest values of the parameters L* and a* (P ≤ 0.05), as there was no white striations on its surface and highest b* value in SG, because of the maximum lipid contents. These results indicate there was a contribution of the SG muscle cells to oversynthesize connective tissue components on the muscle fascia. In conclusion, this study revealed a high incidence of White Striping on broiler commercial line in Brazil thus, there is a need to identify the causes of this abnormality in order to diminish or to eliminate it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collagen%20content" title="collagen content">collagen content</a>, <a href="https://publications.waset.org/abstracts/search?q=commercial%20line" title=" commercial line"> commercial line</a>, <a href="https://publications.waset.org/abstracts/search?q=pectoralis%20major%20muscle" title=" pectoralis major muscle"> pectoralis major muscle</a>, <a href="https://publications.waset.org/abstracts/search?q=proximate%20composition" title=" proximate composition"> proximate composition</a> </p> <a href="https://publications.waset.org/abstracts/43163/occurrence-of-broiler-chicken-breast-white-striping-meat-in-brazilian-commercial-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43163.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">251</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Revealing Single Crystal Quality by Insight Diffraction Imaging Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thu%20Nhi%20Tran%20Caliste">Thu Nhi Tran Caliste</a> </p> <p class="card-text"><strong>Abstract:</strong></p> X-ray Bragg diffraction imaging (“topography”)entered into practical use when Lang designed an “easy” technical setup to characterise the defects / distortions in the high perfection crystals produced for the microelectronics industry. The use of this technique extended to all kind of high quality crystals, and deposited layers, and a series of publications explained, starting from the dynamical theory of diffraction, the contrast of the images of the defects. A quantitative version of “monochromatic topography” known as“Rocking Curve Imaging” (RCI) was implemented, by using synchrotron light and taking advantage of the dramatic improvement of the 2D-detectors and computerised image processing. The rough data is constituted by a number (~300) of images recorded along the diffraction (“rocking”) curve. If the quality of the crystal is such that a one-to-onerelation between a pixel of the detector and a voxel within the crystal can be established (this approximation is very well fulfilled if the local mosaic spread of the voxel is < 1 mradian), a software we developped provides, from the each rocking curve recorded on each of the pixels of the detector, not only the “voxel” integrated intensity (the only data provided by the previous techniques) but also its “mosaic spread” (FWHM) and peak position. We will show, based on many examples, that this new data, never recorded before, open the field to a highly enhanced characterization of the crystal and deposited layers. These examples include the characterization of dislocations and twins occurring during silicon growth, various growth features in Al203, GaNand CdTe (where the diffraction displays the Borrmannanomalous absorption, which leads to a new type of images), and the characterisation of the defects within deposited layers, or their effect on the substrate. We could also observe (due to the very high sensitivity of the setup installed on BM05, which allows revealing these faint effects) that, when dealing with very perfect crystals, the Kato’s interference fringes predicted by dynamical theory are also associated with very small modifications of the local FWHM and peak position (of the order of the µradian). This rather unexpected (at least for us) result appears to be in keeping with preliminary dynamical theory calculations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rocking%20curve%20imaging" title="rocking curve imaging">rocking curve imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=X-ray%20diffraction" title=" X-ray diffraction"> X-ray diffraction</a>, <a href="https://publications.waset.org/abstracts/search?q=defect" title=" defect"> defect</a>, <a href="https://publications.waset.org/abstracts/search?q=distortion" title=" distortion"> distortion</a> </p> <a href="https://publications.waset.org/abstracts/143138/revealing-single-crystal-quality-by-insight-diffraction-imaging-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143138.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">131</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">11</span> The Efficacy of Albendazole against Soil-Transmitted Helminths and the Impact of Mass Drug Administration of Albendazole and Ivermectin on Health Status</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mike%20Yaw%20Osei-Atweneboana">Mike Yaw Osei-Atweneboana</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Asiedu%20Larbi"> John Asiedu Larbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Edward%20Jenner%20Tettevi"> Edward Jenner Tettevi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: The lymphatic filariasis (LF) control programme has been on-going in Ghana since 2000. This community-wide approach involves the use of ivermectin (IVM) and albendazole (ALB). Soil-transmitted helminth (STH) infections control is augmented within this programme; however, in areas where LF is not prevalent, albendazole alone is administered to school children. The purpose of this study was therefore, to determine the efficacy of albendazole against soils transmitted helminths and the impact of mass drug administration of albendazole and ivermectin on the health status of children of school going age and pregnant women. Material/Methods: This was a twelve months longitudinal study. A total of 412 subjects including school children (between the ages of 2-17 years) and pregnant women were randomly selected from four endemic communities in Kpandai district of the Northern region. Coprological assessment for parasites was based on the Kato–Katz technique in both dry and rainy seasons at baseline, 21 days and 3 months post-treatment. Single-dose albendazole treatment was administered to all patients at baseline. Preserved samples are currently under molecular studies to identify possible single nucleotide polymorphism (SNP) within the beta tubulin gene which is associated with benzimidazole resistance. Results: Of all the parasites found (hookworm, Trichuris trichiura, Hymenolepis nana, and Taenia sp.); hookworm was the most prevalent. In the dry season, the overall STHs prevalence at pre-treatment was 29%, while 9% and 13% prevalence was recorded at 21 days, and three months after treatment respectively. However, in the rainy season, the overall STHs prevalence was 8%, while 4% and 12% was recorded at 21 days and three months respectively after ALB treatment. In general, ALB treatment resulted in an overall hookworm egg count reduction rate of 89% in the dry season and 93% in the rainy season, while the T. trichiura egg count reduction rate was 100% in both seasons. Conclusions: STH infections still remains a significant public health burden in Ghana. Hookworm infection seems to respond poorly or sub-optimally to ALB, raising concerns of possible emergence of resistance which may lead to a major setback for the control and elimination of STH infections, especially hookworm infections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hookworm" title="hookworm">hookworm</a>, <a href="https://publications.waset.org/abstracts/search?q=sub-optimal%20response" title=" sub-optimal response"> sub-optimal response</a>, <a href="https://publications.waset.org/abstracts/search?q=albendazole" title=" albendazole"> albendazole</a>, <a href="https://publications.waset.org/abstracts/search?q=trichuriasis" title=" trichuriasis"> trichuriasis</a>, <a href="https://publications.waset.org/abstracts/search?q=soil-transmitted%20helminths" title=" soil-transmitted helminths"> soil-transmitted helminths</a> </p> <a href="https://publications.waset.org/abstracts/50463/the-efficacy-of-albendazole-against-soil-transmitted-helminths-and-the-impact-of-mass-drug-administration-of-albendazole-and-ivermectin-on-health-status" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50463.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">290</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">10</span> Potential of Polyphenols from Tamarix Gallica towards Common Pathological Features of Diabetes and Alzheimer’s Diseases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asma%20Ben%20Hmidene">Asma Ben Hmidene</a>, <a href="https://publications.waset.org/abstracts/search?q=Mizuho%20Hanaki"> Mizuho Hanaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Kazuma%20Murakami"> Kazuma Murakami</a>, <a href="https://publications.waset.org/abstracts/search?q=Kazuhiro%20Irie"> Kazuhiro Irie</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroko%20Isoda"> Hiroko Isoda</a>, <a href="https://publications.waset.org/abstracts/search?q=Hideyuki%20Shigemori"> Hideyuki Shigemori</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Type 2 diabetes mellitus (T2DM) and Alzheimer’s disease (AD) are characterized as a peripheral metabolic disorder and a degenerative disease of the central nervous system, respectively. It is now widely recognized that T2DM and AD share many pathophysiological features including glucose metabolism, increased oxidative stress and amyloid aggregation. Amyloid beta (Aβ) is the components of the amyloid deposits in the AD brain and while the component of the amyloidogenic peptide deposit in the pancreatic islets of Langerhans is identified as human islet amyloid polypeptide (hIAPP). These two proteins are originated from the amyloid precursor protein and have a high sequence similarity. Although the amino acid sequences of amyloidogenic proteins are diverse, they all adopt a similar structure in aggregates called cross-beta-spine. Add at that, extensive studies in the past years have found that like Aβ1-42, IAPP forms early intermediate assemblies as spherical oligomers, implicating that these oligomers possess a common folding pattern or conformation. These similarities can be used in the search for effective pharmacotherapy for DM, since potent therapeutic agents such as antioxidants with a catechol moiety, proved to inhibit Aβ aggregation, may play a key role in the inhibit the aggregation of hIAPP treatment of patients with DM. Tamarix gallica is one of the halophyte species having a powerful antioxidant system. Although it was traditionally used for the treatment of various liver metabolic disorders, there is no report about the use of this plant for the treatment or prevention of T2DM and AD. Therefore, the aim of this work is to investigate their protective effect towards T2DM and AD by isolation and identification of α-glucosidase inhibitors, with antioxidant potential, that play an important role in the glucose metabolism in diabetic patient, as well as, the polymerization of hIAPP and Aβ aggregation inhibitors. Structure-activity relationship study was conducted for both assays. And as for α-glucosidase inhibitors, their mechanism of action and their synergistic potential when applied with a very low concentration of acarbose were also suggesting that they can be used not only as α-glucosidase inhibitors but also be combined with established α-glucosidase inhibitors to reduce their adverse effect. The antioxidant potential of the purified substances was evaluated by DPPH and SOD assays. Th-T assay using 42-mer amyloid β-protein (Aβ42) for AD and hIAPP which is a 37-residue peptide secreted by the pancreatic β –cells for T2DM and Transmission electronic microscopy (TEM) were conducted to evaluate the amyloid aggragation of the actives substances. For α-glucosidase, p-NPG and glucose oxidase assays were performed for determining the inhibition potential and structure-activity relationship study. The Enzyme kinetic protocol was used to study the mechanism of action. From this research, it was concluded that polyphenols playing a role in the glucose metabolism and oxidative stress can also inhibit the amyloid aggregation, and that substances with a catechol and glucuronide moieties inhibiting amyloid-β aggregation, might be used to inhibit the aggregation of hIAPP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=%CE%B1-glucosidase%20inhibitors" title="α-glucosidase inhibitors">α-glucosidase inhibitors</a>, <a href="https://publications.waset.org/abstracts/search?q=amyloid%20aggregation%20inhibition" title=" amyloid aggregation inhibition"> amyloid aggregation inhibition</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanism%20of%20action" title=" mechanism of action"> mechanism of action</a>, <a href="https://publications.waset.org/abstracts/search?q=polyphenols" title=" polyphenols"> polyphenols</a>, <a href="https://publications.waset.org/abstracts/search?q=structure%20activity%20relationship" title=" structure activity relationship"> structure activity relationship</a>, <a href="https://publications.waset.org/abstracts/search?q=synergistic%20potential" title=" synergistic potential"> synergistic potential</a>, <a href="https://publications.waset.org/abstracts/search?q=tamarix%20gallica" title=" tamarix gallica"> tamarix gallica</a> </p> <a href="https://publications.waset.org/abstracts/56581/potential-of-polyphenols-from-tamarix-gallica-towards-common-pathological-features-of-diabetes-and-alzheimers-diseases" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56581.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">279</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> Prevalence and Intensity of Soil Transmitted Helminth Infections among the School Children in the State of Uttar Pradesh, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prasanta%20Saini">Prasanta Saini</a>, <a href="https://publications.waset.org/abstracts/search?q=Junaid%20Jibran%20Jawed"> Junaid Jibran Jawed</a>, <a href="https://publications.waset.org/abstracts/search?q=Subrata%20Majumdar"> Subrata Majumdar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Infections caused by soil-transmitted helminths (STH) are the major problem in all the nations of the world. The major focus of STH research is to study the prevalence of three major helminths, such as Ascaris, Trituris and hookworm. Here we are reporting the prevalence and intensity of the STH in the school children of the state of Uttar Pradesh, India. The aim of the study is to assess the prevalence and risk factors of STH infection among the school children, aged between 5-10 years in 27 districts randomly selected districts with covering nine agro-climatic zones of Uttar Pradesh, India. For this cross-sectional survey, we have selected the populations of government primary school going children in Uttar Pradesh. The sampling was performed in the nine different agro-climatic zones. Every individual of the study populations filled their daily information in the questioner's form and then the sample was collected and processed by kato-katz methods by following the guidelines of WHO. In this method, the sampling was performed in total of 6421 populations. A total of 6,421 children from 130 schools were surveyed. Infection with any soil-transmitted helminths was detected among 4,578 children with an overall prevalence of 75.6% (95% CI: 65.3-83.6). Among the 6421 population, the prevalence of Ascaris is 69.6% (95% CL 57.97-79.11), hookworm is 22.7% (95%CL 19.3-26.3) and Trichuris sp is 4.6% (95% CL 0.8-21.6), so the predicted prevalence map indicates that the STH infection was hyperendemic in this state. The findings of our survey in 130 schools covering 9 agro-climatic with one or more soil transmitted helminths. Majority of STH infections were of light intensity. STH infection was hyper-endemic in entire state, except three zones in western Uttar Pradesh. High prevalence ( > 75%) in all age groups also indicate little impact of existing deworming initiatives, including those among pre-school aged children. WHO recommends annual treatment in areas where STH prevalence is between 20% and 50%, and, a bi-annual treatment in areas with prevalence rates of over 50%. In view of high prevalence of STH infection in Uttar Pradesh, it is strongly recommended to initiate a deworming programme for school children in the state. Although our survey was among primary school children, high prevalence among children aged 4-6 years also indicates the need to strengthen the existing deworming programs for pre-school children. Extending the benefits of deworming to pre-school children through deworming in Anganwadi schools would further reduce to decrease the load of infection in community. As a long-term solution for control STH infection, it is also necessary to improve the sanitation levels in the area, as majority of the houses did not have latrines and most of the children were defecating in open fields, a factor that was found to be significantly associated with STH infection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=prevalence" title="prevalence">prevalence</a>, <a href="https://publications.waset.org/abstracts/search?q=school%20going%20children" title=" school going children"> school going children</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20transmitted%20helminthes" title=" soil transmitted helminthes"> soil transmitted helminthes</a>, <a href="https://publications.waset.org/abstracts/search?q=Uttar%20Pradesh-India" title=" Uttar Pradesh-India"> Uttar Pradesh-India</a> </p> <a href="https://publications.waset.org/abstracts/80538/prevalence-and-intensity-of-soil-transmitted-helminth-infections-among-the-school-children-in-the-state-of-uttar-pradesh-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80538.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">273</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> Nondestructive Inspection of Reagents under High Attenuated Cardboard Box Using Injection-Seeded THz-Wave Parametric Generator </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shin%20Yoneda">Shin Yoneda</a>, <a href="https://publications.waset.org/abstracts/search?q=Mikiya%20Kato"> Mikiya Kato</a>, <a href="https://publications.waset.org/abstracts/search?q=Kosuke%20Murate"> Kosuke Murate</a>, <a href="https://publications.waset.org/abstracts/search?q=Kodo%20Kawase"> Kodo Kawase </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, there have been numerous attempts to smuggle narcotic drugs and chemicals by concealing them in international mail. Combatting this requires a non-destructive technique that can identify such illicit substances in mail. Terahertz (THz) waves can pass through a wide variety of materials, and many chemicals show specific frequency-dependent absorption, known as a spectral fingerprint, in the THz range. Therefore, it is reasonable to investigate non-destructive mail inspection techniques that use THz waves. For this reason, in this work, we tried to identify reagents under high attenuation shielding materials using injection-seeded THz-wave parametric generator (is-TPG). Our THz spectroscopic imaging system using is-TPG consisted of two non-linear crystals for emission and detection of THz waves. A micro-chip Nd:YAG laser and a continuous wave tunable external cavity diode laser were used as the pump and seed source, respectively. The pump beam and seed beam were injected to the LiNbO₃ crystal satisfying the noncollinear phase matching condition in order to generate high power THz-wave. The emitted THz wave was irradiated to the sample which was raster scanned by the x-z stage while changing the frequencies, and we obtained multispectral images. Then the transmitted THz wave was focused onto another crystal for detection and up-converted to the near infrared detection beam based on nonlinear optical parametric effects, wherein the detection beam intensity was measured using an infrared pyroelectric detector. It was difficult to identify reagents in a cardboard box because of high noise levels. In this work, we introduce improvements for noise reduction and image clarification, and the intensity of the near infrared detection beam was converted correctly to the intensity of the THz wave. A Gaussian spatial filter is also introduced for a clearer THz image. Through these improvements, we succeeded in identification of reagents hidden in a 42-mm thick cardboard box filled with several obstacles, which attenuate 56 dB at 1.3 THz, by improving analysis methods. Using this system, THz spectroscopic imaging was possible for saccharides and may also be applied to cases where illicit drugs are hidden in the box, and multiple reagents are mixed together. Moreover, THz spectroscopic imaging can be achieved through even thicker obstacles by introducing an NIR detector with higher sensitivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nondestructive%20inspection" title="nondestructive inspection">nondestructive inspection</a>, <a href="https://publications.waset.org/abstracts/search?q=principal%20component%20analysis" title=" principal component analysis"> principal component analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=terahertz%20parametric%20source" title=" terahertz parametric source"> terahertz parametric source</a>, <a href="https://publications.waset.org/abstracts/search?q=THz%20spectroscopic%20imaging" title=" THz spectroscopic imaging"> THz spectroscopic imaging</a> </p> <a href="https://publications.waset.org/abstracts/75628/nondestructive-inspection-of-reagents-under-high-attenuated-cardboard-box-using-injection-seeded-thz-wave-parametric-generator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75628.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">177</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> Functional Switching of Serratia marcescens Transcriptional Regulator from Activator to Inhibitor of Quorum Sensing by Exogenous Addition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Norihiro%20Kato">Norihiro Kato</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuriko%20Takayama"> Yuriko Takayama</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Some gram-negative bacteria enable the simultaneous activation of gene expression involved in N-acylhomoserine lactone (AHL) dependent cell-to-cell communication system. Such regulatory system for the bacterial group behavior is termed as quorum sensing (QS) because a diffusible AHL signal can accumulate around the cell during the increase of the cell density and trigger activation of the sequential QS process. By blocking the QS, the expression of diverse genes related to infection, antibiotic production, and biofilm formation is inhibited. Conditioning of QS by regulation of the DNA-receptor-AHL interaction is a potential target for enhancing host defenses against pathogenicity. We focused on engineered application of transcriptional regulator SpnR produced in opportunistic human pathogen Serratia marcescens. The SpnR can interact with AHL signals at an N-terminal domain and also with a promoter region of a QS target gene at a C-terminal domain. As the initial process of the QS activation, the SpnR forms a complex with the AHL to enhance the expression of pig cluster; the SpnR normally acts as an activator for the expression of the QS-dependent gene. In this research, we attempt to artificially control QS by changing the role of SpnR. The QS-dependent prodigiosin production is expected to inhibit by externally added SpnR in the culture broth of AS-1 strain because the AHL concentration was kept below the threshold by AHL-SpnR complex formation. Maltose-binding protein (MBP)-tagged SpnR (MBP-SpnR) was overexpressed in Escherichia coli and purified using an affinity chromatography equipped with an amylose resin column. The specific interaction between AHL and MBP-SpnR was demonstrated by quartz crystal microbalance (QCM) sensor. AHL with amino end-group was coupled with COOH-terminated self-assembled monolayer prepared on a gold electrode of 27-MHz quartz crystal sensor using water-soluble carbodiimide. After the injection of MBP-SpnR into a cup-type sensor cell filled with the buffer solution, time course of resonant frequency change (ΔFs) was determined. A decrease of ΔFs clearly showed the uptake of MBP-SpnR onto the AHL-immobilized electrode. Furthermore, no binding affinity was observed after the heat-inactivation of MBP-SpnR at 80ºC. These results suggest that MBP-SpnR possesses a specific affinity for AHL. MBP-SpnR was added to the culture medium as an AHL trap to study inhibitory effects on intracellularly accumulated prodigiosin. With approximately 2 µM MBP-SpnR, the amount of prodigiosin induced was half that of the control without any additives. In conclusion, the function of SpnR could be switched by adding it to the cell culture. Exogenously added MBP-SpnR possesses high affinity for AHL derived from cells and acts as an inhibitor of AHL-mediated QS. <p class="card-text"><strong>Keywords:</strong> <a
