tube for nuclear reactors, because of the excellent corrosion resistance and the low adsorptive material for neutron. Generally speaking, the natural resource of Zr is often containing Hf that has similar properties. The content of Hf in the Zr resources is about 2~4 wt%. In the industrial use, the content of Hf in Zr resources should be lower than the 100 ppm. However, the separation of Zr and Hf is not so easy, because of similar chemical and physical properties such as melting point, boiling point and things. Solvent extraction method has been applied for the separation of Zr and Hf from Zr natural resources. This method can separate Hf with high efficiency (Hf < 100ppm), however, it needs much amount of organic solvents for solvent extraction and the cost of its disposal treatment is high. Therefore, we attached attention for the fractional crystallization. This separation method depends on the solubility difference of Zr and Hf in the solvent. In this work, hexafluorozirconate (hafnate) (K2Zr(Hf)F6) was used as model compound. Solubility of K2ZrF6 in water showed lower than that of K2HfF6. By repeating of this treatment, it is possible to purify Zr, practically. In this case, 16-18 times of recrystallization stages were needed for its high purification. The improvement of the crystallization process was carried out in this work. Water, hydrofluoric acid (HF) and hydrofluoric acid (HF) +hydrochloric acid (HCl) mixture were chosen as solvent for dissolution of Zr and Hf. In the experiment, 10g of K2ZrF6 was added to each solvent of 100mL. Each solution was heated for 1 hour at 353K. After 1h of this operation, they were cooled down till 293K, and were held for 5 hours at 273K. Concentration of Zr or Hf was measured using ICP analysis. It was found that Hf was separated from Zr-Hf mixed compound with high efficiency, when HF-HCl solution was used for solvent of crystallization. From the comparison of the particle size of each crystal by SEM, it was confirmed that the particle diameter of the crystal showed smaller size with decreasing of Hf content. This paper concerned with purification of Zr from Zr-Hf mixture using crystallization method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crystallization" title="crystallization">crystallization</a>, <a href="https://publications.waset.org/abstracts/search?q=zirconium" title=" zirconium"> zirconium</a>, <a href="https://publications.waset.org/abstracts/search?q=hafnium" title=" hafnium"> hafnium</a>, <a href="https://publications.waset.org/abstracts/search?q=separation" title=" separation"> separation</a> </p> <a href="https://publications.waset.org/abstracts/35531/purification-of-zr-from-zr-hf-resources-using-crystallization-in-hf-hcl-solvent-mixture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35531.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">437</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">41</span> Evaluation of Different Anticoagulant Effects on Flow Properties of Human Blood Using Falling Needle Rheometer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hiroki%20Tsuneda">Hiroki Tsuneda</a>, <a href="https://publications.waset.org/abstracts/search?q=Takamasa%20Suzuki"> Takamasa Suzuki</a>, <a href="https://publications.waset.org/abstracts/search?q=Hideki%20Yamamoto"> Hideki Yamamoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Kimito%20Kawamura"> Kimito Kawamura</a>, <a href="https://publications.waset.org/abstracts/search?q=Eiji%20Tamura"> Eiji Tamura</a>, <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Wochner"> Katharina Wochner</a>, <a href="https://publications.waset.org/abstracts/search?q=Roberto%20Plasenzotti"> Roberto Plasenzotti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flow property of human blood is one of the important factors on the prevention of the circulatory condition such as a high blood pressure, a diabetes mellitus, and a cardiac infarction. However, the measurement of flow property of human blood, especially blood viscosity, is not so easy, because of their coagulation or aggregation behaviors after taking a sample from blood vessel. In the experiment, some kinds of anticoagulant were added into the human blood to avoid its solidification. Anticoagulant used in the blood test has been chosen for each purpose of blood test, for anticoagulant effect on blood is different mechanism for each. So that, there is a problem that the evaluation of measured blood property with different anticoagulant is so difficult. Therefore, it is so important to make clear the difference of anticoagulant effect on the blood property. In the previous work, a compact-size falling needle rheometer (FNR) has been developed in order to measure the flow property of human blood such as a flow curve, an apparent viscosity. It was found that FNR system can apply to a rheometer or a viscometry for various experimental conditions for not only human blood but also mammalians blood. In this study, the measurements of human blood viscosity with different anticoagulant (EDTA and Heparin) were carried out using newly developed FNR system. The effect of anticoagulant on blood viscosity was also tested by using the standard liquid for each. The accuracy on the viscometry was also tested by using the standard liquid for calibrating materials (JS-10, JS-20) and observed data have satisfactory agreement with reference data around 1.0% at 310K. The flow curve of six males and females with different anticoagulant were measured using FNR. In this experiment, EDTA and Heparin were chosen as anticoagulant for blood. Heparin can inhibit the coagulation of human blood by activating the body of anti-thrombin. To examine the effect of human blood viscosity on anticoagulant, flow curve was measured at high shear rate (＞350s-1), and apparent viscosity of each person were determined with different anticoagulant. The apparent viscosity of human blood with heparin was 2%-9% higher than that with EDTA. However, the difference of blood viscosity for two anticoagulants for same blood was different for each. Further discussion, we need the consideration of effect on other physical property, such as cellular component and plasma component. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=falling-needle%20rheometer" title="falling-needle rheometer">falling-needle rheometer</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20blood" title=" human blood"> human blood</a>, <a href="https://publications.waset.org/abstracts/search?q=viscosity" title=" viscosity"> viscosity</a>, <a href="https://publications.waset.org/abstracts/search?q=anticoagulant" title=" anticoagulant"> anticoagulant</a> </p> <a href="https://publications.waset.org/abstracts/35527/evaluation-of-different-anticoagulant-effects-on-flow-properties-of-human-blood-using-falling-needle-rheometer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35527.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">40</span> Thermal Decomposition Behaviors of Hexafluoroethane (C2F6) Using Zeolite/Calcium Oxide Mixtures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kazunori%20Takai">Kazunori Takai</a>, <a href="https://publications.waset.org/abstracts/search?q=Weng%20Kaiwei"> Weng Kaiwei</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadao%20Araki"> Sadao Araki</a>, <a href="https://publications.waset.org/abstracts/search?q=Hideki%20Yamamoto"> Hideki Yamamoto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> HFC and PFC gases have been commonly and widely used as refrigerant of air conditioner and as etching agent of semiconductor manufacturing process, because of their higher heat of vaporization and chemical stability. On the other hand, HFCs and PFCs gases have the high global warming effect on the earth. Therefore, we have to be decomposed these gases emitted from chemical apparatus like as refrigerator. Until now, disposal of these gases were carried out by using combustion method like as Rotary kiln treatment mainly. However, this treatment needs extremely high temperature over 1000 °C. In the recent year, in order to reduce the energy consumption, a hydrolytic decomposition method using catalyst and plasma decomposition treatment have been attracted much attention as a new disposal treatment. However, the decomposition of fluorine-containing gases under the wet condition is not able to avoid the generation of hydrofluoric acid. Hydrofluoric acid is corrosive gas and it deteriorates catalysts in the decomposition process. Moreover, an additional process for the neutralization of hydrofluoric acid is also indispensable. In this study, the decomposition of C2F6 using zeolite and zeolite/CaO mixture as reactant was evaluated in the dry condition at 923 K. The effect of the chemical structure of zeolite on the decomposition reaction was confirmed by using H-Y, H-Beta, H-MOR and H-ZSM-5. The formation of CaF2 in zeolite/CaO mixtures after the decomposition reaction was confirmed by XRD measurements. The decomposition of C2F6 using zeolite as reactant showed the closely similar behaviors regardless the type of zeolite (MOR, Y, ZSM-5, Beta type). There was no difference of XRD patterns of each zeolite before and after reaction. On the other hand, the difference in the C2F6 decomposition for each zeolite/CaO mixtures was observed. These results suggested that the rate-determining process for the C2F6 decomposition on zeolite alone is the removal of fluorine from reactive site. In other words, the C2F6 decomposition for the zeolite/CaO improved compared with that for the zeolite alone by the removal of the fluorite from reactive site. HMOR/CaO showed 100% of the decomposition for 3.5 h and significantly improved from zeolite alone. On the other hand, Y type zeolite showed no improvement, that is, the almost same value of Y type zeolite alone. The descending order of C2F6 decomposition was MOR, ZSM-5, beta and Y type zeolite. This order is similar to the acid strength characterized by NH3-TPD. Hence, it is considered that the C-F bond cleavage is closely related to the acid strength. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hexafluoroethane" title="hexafluoroethane">hexafluoroethane</a>, <a href="https://publications.waset.org/abstracts/search?q=zeolite" title=" zeolite"> zeolite</a>, <a href="https://publications.waset.org/abstracts/search?q=calcium%20oxide" title=" calcium oxide"> calcium oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=decomposition" title=" decomposition"> decomposition</a> </p> <a href="https://publications.waset.org/abstracts/35529/thermal-decomposition-behaviors-of-hexafluoroethane-c2f6-using-zeolitecalcium-oxide-mixtures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35529.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">481</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">39</span> Preparation of hydrophobic silica membranes supported on alumina hollow fibers for pervaporation applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ami%20Okabe">Ami Okabe</a>, <a href="https://publications.waset.org/abstracts/search?q=Daisuke%20Gondo"> Daisuke Gondo</a>, <a href="https://publications.waset.org/abstracts/search?q=Akira%20Ogawa"> Akira Ogawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasuhisa%20Hasegawa"> Yasuhisa Hasegawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Koichi%20Sato"> Koichi Sato</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadao%20Araki"> Sadao Araki</a>, <a href="https://publications.waset.org/abstracts/search?q=Hideki%20Yamamoto"> Hideki Yamamoto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Membrane separation draws attention as the energy-saving technology. Pervaporation (PV) uses hydrophobic ceramic membranes to separate organic compounds from industrial wastewaters. PV makes it possible to separate organic compounds from azeotropic mixtures and from aqueous solutions. For the PV separation of low concentrations of organics from aqueous solutions, hydrophobic ceramic membranes are expected to have high separation performance compared with that of conventional hydrophilic membranes. Membrane separation performance is evaluated based on the pervaporation separation index (PSI), which depends on both the separation factor and the permeate flux. Ingenuity is required to increase the PSI such that the permeate flux increases without reducing the separation factor or to increase the separation factor without reducing the flux. A thin separation layer without defects and pinholes is required. In addition, it is known that the flux can be increased without reducing the separation factor by reducing the diffusion resistance of the membrane support. In a previous study, we prepared hydrophobic silica membranes by a molecular templating sol−gel method using cetyltrimethylammonium bromide (CTAB) to form pores suitable for permitting the passage of organic compounds through the membrane. We separated low-concentration organics from aqueous solutions by PV using these membranes. In the present study, hydrophobic silica membranes were prepared on a porous alumina hollow fiber support that is thinner than the previously used alumina support. Ethyl acetate (EA) is used in large industrial quantities, so it was selected as the organic substance to be separated. Hydrophobic silica membranes were prepared by dip-coating porous alumina supports with a -alumina interlayer into a silica sol containing CTAB and vinyltrimethoxysilane (VTMS) as the silica precursor. Membrane thickness increases with the lifting speed of the sol in the dip-coating process. Different thicknesses of the γ-alumina layer were prepared by dip-coating the support into a boehmite sol at different lifting speeds (0.5, 1, 3, and 5 mm s-1). Silica layers were subsequently formed by dip-coating using an immersion time of 60 s and lifting speed of 1 mm s-1. PV measurements of the EA (5 wt.%)/water system were carried out using VTMS hydrophobic silica membranes prepared on -alumina layers of different thicknesses. Water and EA flux showed substantially constant value despite of the change of the lifting speed to form the γ-alumina interlayer. All prepared hydrophobic silica membranes showed the higher PSI compared with the hydrophobic membranes using the previous alumina support of hollow fiber. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=membrane%20separation" title="membrane separation">membrane separation</a>, <a href="https://publications.waset.org/abstracts/search?q=pervaporation" title=" pervaporation"> pervaporation</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrophobic" title=" hydrophobic"> hydrophobic</a>, <a href="https://publications.waset.org/abstracts/search?q=silica" title=" silica"> silica</a> </p> <a href="https://publications.waset.org/abstracts/35530/preparation-of-hydrophobic-silica-membranes-supported-on-alumina-hollow-fibers-for-pervaporation-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35530.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">404</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> Round Addition DFA on Lightweight Block Ciphers with On-The-Fly Key Schedule</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hideki%20Yoshikawa">Hideki Yoshikawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Masahiro%20Kaminaga"> Masahiro Kaminaga</a>, <a href="https://publications.waset.org/abstracts/search?q=Arimitsu%20Shikoda"> Arimitsu Shikoda</a>, <a href="https://publications.waset.org/abstracts/search?q=Toshinori%20Suzuki"> Toshinori Suzuki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Round addition differential fault analysis (DFA) using operation bypassing for lightweight block ciphers with on-the-fly key schedule is presented.

The wastewater from chemical plants often contains organic compounds such as ethyl acetate (EA), methylethyl ketone (MEK) and isopropyl alcohol (IPA). In this study, we prepared hydrophobic silica membranes by a sol-gel method. We used phenyltrimethoxysilane (PhTMS), ethyltrimethoxysilan (ETMS), Propyltrimethoxysilane (PrTMS), N-butyltrimethoxysilane (BTMS), N-Hexyltrimethoxysilane (HTMS) as silica sources to introduce each functional groups on the membrane surface. Cetyltrimethyl ammonium bromide (CTAB) was used as a molecular template to create suitable pore that enable the permeation of organic compounds. These membranes with five different functional groups were characterized by SEM, FT-IR, and permporometry. Thicknesses and pore diameters of silica layer for all membrane were about 1.0 μm and about 1 nm, respectively. In other words, functional groups had an insignificant effect on the membrane thicknesses and the formation of the pore by CTAB. We confirmed the effect of functional groups on the flux and separation factor for ethyl acetate (EA), methyl ethyl ketone, acetone and 1-butanol (1-BtOH) /water mixtures. All membranes showed a high flux for ethyl acetate compared with other compounds. In particular, the hydrophobic silica membrane prepared by using BTMS showed 0.75 kg m-2 h-1 of flux for EA. For all membranes, the fluxes of organic compounds showed the large values in the order corresponding to EA > MEK > acetone > 1-BtOH. On the other hand, carbon chain length of functional groups among ETMS, PrTMS, BTMS, PrTMS and HTMS did not have a major effect on the organic flux. Although we confirmed the relationship between organic fluxes and organic molecular diameters or fugacity of organic compounds, these factors had a low correlation with organic fluxes. It is considered that these factors affect the diffusivity. Generally, permeation through membranes is based on the diffusivity and solubility. Therefore, it is deemed that organic fluxes through these hydrophobic membranes are strongly influenced by solubility. We tried to estimate the organic fluxes by Hansen solubility parameter (HSP). HSP, which is based on the cohesion energy per molar volume and is composed of dispersion forces (δd), intermolecular dipole interactions (δp), and hydrogen-bonding interactions (δh), has recently attracted attention as a means for evaluating the resolution and aggregation behavior. Evaluation of solubility for two substances can be represented by using the Ra [(MPa)1/2] value, meaning the distance of HSPs for both of substances. A smaller Ra value means a higher solubility for each substance. On the other hand, it can be estimated that the substances with large Ra value show low solubility. We established the correlation equation, which was based on Ra, of organic flux at low concentrations of organic compounds and at 295-325 K. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrophobic" title="hydrophobic">hydrophobic</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane" title=" membrane"> membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=Hansen%20solubility%20parameter" title=" Hansen solubility parameter"> Hansen solubility parameter</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20group" title=" functional group"> functional group</a> </p> <a href="https://publications.waset.org/abstracts/35524/organic-permeation-properties-of-hydrophobic-silica-membranes-with-different-functional-groups" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35524.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">378</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> Feature of Employment Injuries and Maintenance Works of Construction Machinery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naoko%20Kanazawa">Naoko Kanazawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Tran%20Thi%20Bich%20Nguyet"> Tran Thi Bich Nguyet</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoshiyuki%20Higuchi"> Yoshiyuki Higuchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hideki%20Hamada"> Hideki Hamada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Construction machines’ condition is maintained with the regularly inspections, preventive maintenance and repairs by skillful and qualified engineers.

While artificial turf fields are increasing in popularity due to lower maintenance costs, artificial turf has been associated with more ankle and knee injuries, with inconclusive data on concussions. In this study, natural grass and artificial football fields were compared in terms of deceleration on fall impact. Methods: Accelerometers were placed on the forehead, apex of the head, and right ear of a Century Body Opponent Bag (BOB) manikin. A Riddell HITS football helmet was secured onto the head of the manikin over the accelerometers. This manikin was dropped onto natural grass (n = 10) and artificial turf (n = 9) high school football fields. The manikin was dropped from a stationary position at a height of 60 cm onto its front, back, and left side. Each of these drops was conducted 10 times at the 40-yard line, 20-yard line, and endzone. The net deceleration on impact was calculated as a net vector from each of the three accelerometers’ x, y, and z vectors from the three different locations on the manikin’s head (9 vector measurements per drop). Results: Mean values for the multiple drops were calculated for each accelerometer and drop type for each field. All accelerometers in forward and backward falls and one accelerometer in side falls showed significantly greater impact force on synthetic turf compared to the natural grass surfaces. Conclusion: Impact force was higher on synthetic fields for all drop types for at least one of the accelerometer locations. These findings suggest that concussion risk might be higher for athletes playing on artificial turf fields. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concussion" title="concussion">concussion</a>, <a href="https://publications.waset.org/abstracts/search?q=football" title=" football"> football</a>, <a href="https://publications.waset.org/abstracts/search?q=biomechanics" title=" biomechanics"> biomechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=sports" title=" sports"> sports</a> </p> <a href="https://publications.waset.org/abstracts/147563/impact-force-difference-on-natural-grass-versus-synthetic-turf-football-fields" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147563.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">158</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> Exciting Voltage Control for Efficiency Maximization for 2-D Omni-Directional Wireless Power Transfer Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masato%20Sasaki">Masato Sasaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Masayoshi%20Yamamoto"> Masayoshi Yamamoto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The majority of wireless power transfer (WPT) systems transfer power in a directional manner.

The sugarcane straw was collected after the harvest and taken to the drying oven, and then it was crushed in the mill type Willey. Analyzes of ash contents and Klason lignin were done in triplicate and high heating value (HHV) in duplicate, according to ASTM standard. The results obtained for the sugarcane straw were 5.29% for ash content, 29.87% for Klason lignin and 17.67 MJ.kg-1 for HHV. Also, the material was analyzed by scanning electron microscope (SEM). The presence of contaminants was observed, such as silica. The high amount of contaminants in the samples may impact the results of analyzes, also raising its values, for example in the Klason lignin content. These contaminants can also adversely affect the quality of the biomass. Even using the standards is important to know what the purpose of the analysis and care mainly of sampling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomass" title="biomass">biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=bioenergy" title=" bioenergy"> bioenergy</a>, <a href="https://publications.waset.org/abstracts/search?q=residues" title=" residues"> residues</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20fuel" title=" solid fuel"> solid fuel</a> </p> <a href="https://publications.waset.org/abstracts/49208/interference-of-contaminants-in-the-characterization-of-sugarcane-straw-for-energy-purpose" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49208.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">281</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">29</span> Affinity between Sociology and Islamic Economy: An Inquiry into the Possibilities of Social Constructivism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hideki%20Kitamura">Hideki Kitamura</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Since Islamic banking has broadly started in the late 1970s, Islamic economy has been paid much attention by both academia and the business world. However, despite abundant studies, descriptive exploration of practices of Islamic economy from a sociological/anthropological perspective is underrepresented, and most are basically designed for evaluating current practice or proposing ideal types of Islamic economy in accordance with their religious conviction. Overall, their interest is not paid to actors of Islamic economy such as practitioner’s decision-making and thought, while sociological/anthropological studies on Muslim’s religious life can be observed well. Herein, the paper aims to look into the possibilities of sociology/anthropology for exploration of the role of actors of Islamic economy, by revisiting the benefit of sociological/anthropological studies on the religion of Islam and its adaptability to the research on Islamic economy. The paper suggests that practices of Islamic economy can be assumed as results of practitioner’s dilemma between Islamic ideals and market realities in each society, by applying the perspective of social constructivism. The paper then proposes focusing on the human agency of practitioners in translating Islamic principles into economic behavior, thereby enabling a more descriptive inquiry into how Islamic economy is produced and operated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Islamic%20economy" title="Islamic economy">Islamic economy</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20sociology%2Fanthropology" title=" economic sociology/anthropology"> economic sociology/anthropology</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20agency" title=" human agency"> human agency</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20constructivism" title=" social constructivism"> social constructivism</a> </p> <a href="https://publications.waset.org/abstracts/103639/affinity-between-sociology-and-islamic-economy-an-inquiry-into-the-possibilities-of-social-constructivism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103639.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">158</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">28</span> Morphology of the Acetabular Cartilage Surface in Elderly Cadavers Analyzing the Contact between the Acetabulum and Femoral Head</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Keisuke%20Akiyama">Keisuke Akiyama</a>, <a href="https://publications.waset.org/abstracts/search?q=Takashi%20Sakai"> Takashi Sakai</a>, <a href="https://publications.waset.org/abstracts/search?q=Junichiro%20Koyanagi"> Junichiro Koyanagi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hideki%20Yoshikawa"> Hideki Yoshikawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Kazuomi%20Sugamoto"> Kazuomi Sugamoto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The geometry of acetabular cartilage surface plays an important role in hip joint biomechanics. The aim of this study was to analyze the morphology of acetabular articular cartilage surface in elderly subjects using a 3D-digitizer. Twenty hemipelves from 12 subjects (mean ages 85 years) were scanned with 3D-digitizer. Each acetabular surface model was divided into four regions: anterosuperior (AS), anteroinferior (AI), posterosuperior (PS), and posteroinferior (PI). In the global acetabulum and each region, the acetabular sphere radius and the standard deviation (SD) of the distance from the acetabular sphere center to the acetabular cartilage surface were calculated. In the global acetabulum, the distance between the acetabular surface model and the maximum sphere which did not penetrate over the acetabular surface model was calculated as the inferred femoral head, and then the distribution was mapped at intervals of 0.5 mm. The SD in AS was significantly larger than that in AI (p = 0.006) and PI (p = 0.001). The SD in PS was significantly larger than that in PI (p = 0.005). The closest region (0-0.5 mm) tended to be distributed at anterior or posterosuperior acetabular edge. The contact between the femoral head and acetabulum might start at the periphery of the lunate surface, especially in the anterior or posterosuperior region. From viewpoint of acetabular morphology, the acetabular articular cartilage in the anterior or posterosuperior edge could be more vulnerable due to direct contact mechanism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acetabulum" title="acetabulum">acetabulum</a>, <a href="https://publications.waset.org/abstracts/search?q=cartilage" title=" cartilage"> cartilage</a>, <a href="https://publications.waset.org/abstracts/search?q=morphology" title=" morphology"> morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=3D-digitizer" title=" 3D-digitizer"> 3D-digitizer</a> </p> <a href="https://publications.waset.org/abstracts/24941/morphology-of-the-acetabular-cartilage-surface-in-elderly-cadavers-analyzing-the-contact-between-the-acetabulum-and-femoral-head" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24941.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">345</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">27</span> Seismic Behavior of Masonry Reinforced Concrete Composite Columns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hassane%20Ousalem">Hassane Ousalem</a>, <a href="https://publications.waset.org/abstracts/search?q=Hideki%20Kimura"> Hideki Kimura</a>, <a href="https://publications.waset.org/abstracts/search?q=Akitoshi%20Hamada"> Akitoshi Hamada</a>, <a href="https://publications.waset.org/abstracts/search?q=Masuda%20Hiroyuki"> Masuda Hiroyuki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To provide tall unreinforced brick masonry walls of a century-old existing building with sufficient resistance against earthquake loading actions, additional reinforced concrete columns were integrated into the building at some designated locations and jointed to the existing masonry walls through dowel shear steel bars, resulting in composite structural elements. As conditions at the interface between the existing masonry and newly added reinforced concrete parts were not well grasped and the behavior of such composite elements would be complex, the experimental investigation was carried out. Three relatively large specimens were tested to investigate the overall behavior of brick masonry-reinforced concrete composite elements under lateral cyclic loadings. Confining the brick walls on only one side or on two opposite sides, as well as providing different amounts of dowel shear steel bars at the interface were the main parameters of the investigation. Test results showed that such strengthening provide a good seismic performance even at very large lateral drifts and the investigated amount of shear dowel lead to a good performance level that would result in a considerable cost reduction of the strengthening. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=unreinforced%20masonry" title="unreinforced masonry">unreinforced masonry</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete" title=" reinforced concrete"> reinforced concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20column" title=" composite column"> composite column</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20strengthening" title=" seismic strengthening"> seismic strengthening</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20testing" title=" structural testing"> structural testing</a> </p> <a href="https://publications.waset.org/abstracts/90689/seismic-behavior-of-masonry-reinforced-concrete-composite-columns" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90689.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">217</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> Surface Modification of Polyethylene Terephthalate Substrates via Direct Fluorination to Promote the Ag+ Ions Adsorption</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kohei%20Yamamoto">Kohei Yamamoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Ho%20Kim"> Jae-Ho Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Susumu%20Yonezawa"> Susumu Yonezawa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The surface of polyethylene terephthalate (PET) was modified with fluorine gas at 25 ℃ and 100 Torr for one h. Moreover, the effect of ethanol washing on surface modification was investigated in this study. The surface roughness of the fluorinated and washed PET samples was approximately six times larger than that (0.6 nm) of the untreated thing. The results of Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy showed that the bonds such as -C=O and -C-Hx derived from raw PET decreased and were converted into fluorinated bonds such as -CFx after surface fluorination. Even after washing with ethanol, the fluorinated bonds stably existed on the surface. These fluorinated bonds showed higher electronegativity according to the zeta potential results. The negative surface charges were increased by washing the ethanol, and it caused to increase in the number of polar groups such as -CHF- and -C-Fx. The fluorinated and washed surface of PET could promote the adsorption of Ag+ ions in AgNO₃ solution because of the increased surface roughness and the negatively charged surface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ag%2B%20ions%20adsorption" title="Ag+ ions adsorption">Ag+ ions adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=polyethylene%20terephthalate" title=" polyethylene terephthalate"> polyethylene terephthalate</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20fluorination" title=" surface fluorination"> surface fluorination</a>, <a href="https://publications.waset.org/abstracts/search?q=zeta%20potential" title=" zeta potential"> zeta potential</a> </p> <a href="https://publications.waset.org/abstracts/152869/surface-modification-of-polyethylene-terephthalate-substrates-via-direct-fluorination-to-promote-the-ag-ions-adsorption" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152869.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">121</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">25</span> Analysis of the Performance of a Solar Water Heating System with Flat Collector</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Georgi%20Vendramin">Georgi Vendramin</a>, <a href="https://publications.waset.org/abstracts/search?q=Aurea%20L%C3%BAcia"> Aurea Lúcia</a>, <a href="https://publications.waset.org/abstracts/search?q=Yamamoto"> Yamamoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Itsuo"> Carlos Itsuo</a>, <a href="https://publications.waset.org/abstracts/search?q=Camargo%20Nogueira"> Camargo Nogueira</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Eduardo"> Carlos Eduardo</a>, <a href="https://publications.waset.org/abstracts/search?q=Lenz"> Lenz</a>, <a href="https://publications.waset.org/abstracts/search?q=Anderson%20Miguel"> Anderson Miguel</a>, <a href="https://publications.waset.org/abstracts/search?q=Souza%20Melegari"> Souza Melegari</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20N."> Samuel N.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The thermal performance of a solar water heating with 1.00 m2 flat plate collectors in Cascavel-PR, is which presented in this article, paper presents the solution to leverage the marketing of solar heating systems through detailed constituent materials of the solar collector studies, these abundant materials in construction, such as expanded polyethylene, PVC, aluminum and glass tubes, mixing them with new materials to minimize loss of efficiency while decreasing its cost.

As well known, the huge earthquake in Japan 2011 induced a huge tsunami and the tsunami caused serious damage in the Tohoku and Kanto area. Although breakwaters were constructed in the coast to suppress the tsunami, these were collapsed, and it resulted in severe disasters. In order to decrease the tsunami disaster, we propose the submerged breakwaters and investigate its effect on the tsunami behavior by means of numerical simulations. In order to reproduce tsunami and capture its interface, we employed a moving particle method which is one of the Lagragian methods. Different from ordinary breakwaters, the present breakwater is located in the under-sea. An effective installation condition is investigated by the parametric study. The results show that the submerged breakwater can decrease the wave force by the tsunami. Moreover, the combination of two submerged breakwaters can reduce the tsunami safely and effectively. Therefore, the present results give the effective condition of the installation of the under-sea breakwaters and its mechanism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coastal%20area" title="coastal area">coastal area</a>, <a href="https://publications.waset.org/abstracts/search?q=tsunami%20force%20reduction" title=" tsunami force reduction"> tsunami force reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=MPS%20method" title=" MPS method"> MPS method</a>, <a href="https://publications.waset.org/abstracts/search?q=submerged%20breakwater" title=" submerged breakwater"> submerged breakwater</a> </p> <a href="https://publications.waset.org/abstracts/88772/numerical-investigation-on-tsunami-suppression-by-submerged-breakwater" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88772.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">164</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">23</span> Retail Strategy to Reduce Waste Keeping High Profit Utilizing Taylor's Law in Point-of-Sales Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gen%20Sakoda">Gen Sakoda</a>, <a href="https://publications.waset.org/abstracts/search?q=Hideki%20Takayasu"> Hideki Takayasu</a>, <a href="https://publications.waset.org/abstracts/search?q=Misako%20Takayasu"> Misako Takayasu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Waste reduction is a fundamental problem for sustainability. Methods for waste reduction with point-of-sales (POS) data are proposed, utilizing the knowledge of a recent econophysics study on a statistical property of POS data. Concretely, the non-stationary time series analysis method based on the Particle Filter is developed, which considers abnormal fluctuation scaling known as Taylor's law. This method is extended for handling incomplete sales data because of stock-outs by introducing maximum likelihood estimation for censored data. The way for optimal stock determination with pricing the cost of waste reduction is also proposed. This study focuses on the examination of the methods for large sales numbers where Taylor's law is obvious. Numerical analysis using aggregated POS data shows the effectiveness of the methods to reduce food waste maintaining a high profit for large sales numbers. Moreover, the way of pricing the cost of waste reduction reveals that a small profit loss realizes substantial waste reduction, especially in the case that the proportionality constant  of Taylor’s law is small. Specifically, around 1% profit loss realizes half disposal at =0.12, which is the actual  value of processed food items used in this research. The methods provide practical and effective solutions for waste reduction keeping a high profit, especially with large sales numbers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20waste%20reduction" title="food waste reduction">food waste reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20filter" title=" particle filter"> particle filter</a>, <a href="https://publications.waset.org/abstracts/search?q=point-of-sales" title=" point-of-sales"> point-of-sales</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20development%20goals" title=" sustainable development goals"> sustainable development goals</a>, <a href="https://publications.waset.org/abstracts/search?q=Taylor%27s%20law" title=" Taylor's law"> Taylor's law</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20series%20analysis" title=" time series analysis"> time series analysis</a> </p> <a href="https://publications.waset.org/abstracts/112690/retail-strategy-to-reduce-waste-keeping-high-profit-utilizing-taylors-law-in-point-of-sales-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112690.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">22</span> Application of Medium High Hydrostatic Pressure in Preserving Textural Quality and Safety of Pineapple Compote</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nazim%20Uddin">Nazim Uddin</a>, <a href="https://publications.waset.org/abstracts/search?q=Yohiko%20Nakaura"> Yohiko Nakaura</a>, <a href="https://publications.waset.org/abstracts/search?q=Kazutaka%20Yamamoto"> Kazutaka Yamamoto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Compote (fruit in syrup) of pineapple (<em>Ananas</em> <em>comosus</em> L. Merrill) is expected to have a high market potential as one of convenient ready-to-eat (RTE) foods worldwide. High hydrostatic pressure (HHP) in combination with low temperature (LT) was applied to the processing of pineapple compote as well as medium HHP (MHHP) in combination with medium-high temperature (MHT) since both processes can enhance liquid impregnation and inactivate microbes. MHHP+MHT (55 or 65 °C) process, as well as the HHP+LT process, has successfully inactivated the microbes in the compote to a non-detectable level. Although the compotes processed by MHHP+MHT or HHP+LT have lost the fresh texture as in a similar manner as those processed solely by heat, it was indicated that the texture degradations by heat were suppressed under MHHP. Degassing process reduced the hardness, while calcium (Ca) contributed to be retained hardness in MHT and MHHP+MHT processes. Electrical impedance measurement supported the damage due to degassing and heat. The color, Brix, and appearance were not affected by the processing methods significantly. MHHP+MHT and HHP+LT processes may be applicable to produce high-quality, safe RTE pineapple compotes. Further studies on the optimization of packaging and storage condition will be indispensable for commercialization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compote%20of%20pineapple" title="compote of pineapple">compote of pineapple</a>, <a href="https://publications.waset.org/abstracts/search?q=RTE" title=" RTE"> RTE</a>, <a href="https://publications.waset.org/abstracts/search?q=medium%20high%20hydrostatic%20pressure" title=" medium high hydrostatic pressure"> medium high hydrostatic pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=postharvest%20loss" title=" postharvest loss"> postharvest loss</a>, <a href="https://publications.waset.org/abstracts/search?q=texture" title=" texture"> texture</a> </p> <a href="https://publications.waset.org/abstracts/110564/application-of-medium-high-hydrostatic-pressure-in-preserving-textural-quality-and-safety-of-pineapple-compote" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110564.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">137</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> Lean Manufacturing: Systematic Layout Planning Application to an Assembly Line Layout of a Welding Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fernando%20Augusto%20Ullmann%20Tobe">Fernando Augusto Ullmann Tobe</a>, <a href="https://publications.waset.org/abstracts/search?q=Moacyr%20Amaral%20Domingues"> Moacyr Amaral Domingues</a>, <a href="https://publications.waset.org/abstracts/search?q=Figueiredo"> Figueiredo</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephany%20Rie%20Yamamoto%20Gushiken"> Stephany Rie Yamamoto Gushiken</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this paper is to present the process of elaborating the layout of an assembly line of a welding industry using the principles of lean manufacturing as the main driver. The objective of this paper is relevant since the current layout of the assembly line causes non-productive times for operators, being related to the lean waste of unnecessary movements. The methodology used for the project development was Project-based Learning (PBL), which is an active way of learning focused on real problems. The process of selecting the methodology for layout planning was developed considering three criteria to evaluate the most relevant one for this paper's goal. As a result of this evaluation, Systematic Layout Planning was selected, and three steps were added to it – Value Stream Mapping for the current situation and after layout changed and the definition of lean tools and layout type. This inclusion was to consider lean manufacturing in the layout redesign of the industry. The layout change resulted in an increase in the value-adding time of operations carried out in the sector, reduction in movement times between previous and final assemblies, and in cost savings regarding the man-hour value of the employees, which can be invested in productive hours instead of movement times. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assembly%20line" title="assembly line">assembly line</a>, <a href="https://publications.waset.org/abstracts/search?q=layout" title=" layout"> layout</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20manufacturing" title=" lean manufacturing"> lean manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=systematic%20layout%20planning" title=" systematic layout planning"> systematic layout planning</a> </p> <a href="https://publications.waset.org/abstracts/135739/lean-manufacturing-systematic-layout-planning-application-to-an-assembly-line-layout-of-a-welding-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135739.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">226</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> Biocompatibility and Electrochemical Assessment of Biomedical Ti-24Nb-4Zr-8Sn Produced by Spark Plasma Sintering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jerman%20Madonsela">Jerman Madonsela</a>, <a href="https://publications.waset.org/abstracts/search?q=Wallace%20%20Matizamhuka"> Wallace Matizamhuka</a>, <a href="https://publications.waset.org/abstracts/search?q=Akiko%20%20Yamamoto"> Akiko Yamamoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Ronald%20Machaka"> Ronald Machaka</a>, <a href="https://publications.waset.org/abstracts/search?q=Brendon%20Shongwe"> Brendon Shongwe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, biocompatibility evaluation of nanostructured near beta Ti-24Nb-4Zr-8Sn (Ti2448) alloy with non-toxic elements produced utilizing Spark plasma sintering (SPS) of very fine microsized powders attained through mechanical alloying was performed. The results were compared with pure titanium and Ti-6Al-4V (Ti64) alloy. Cell proliferation test was performed using murine osteoblastic cells, MC3T3-E1 at two cell densities; 400 and 4000 cells/mL for 7 days incubation. Pure titanium took a lead under both conditions suggesting that the presence of other oxide layers influence cell proliferation. No significant difference in cell proliferation was observed between Ti64 and Ti2448. Potentiodynamic measurement in Hanks, 0.9% NaCl and cell culture medium showed no distinct difference on the anodic polarization curves of the three alloys, indicating that the same anodic reaction occurred on their surface but with different rates. However, Ti2448 showed better corrosion resistance in cell culture medium with a slightly lower corrosion rate of 2.96 nA/cm2 compared to 4.86 nA/cm2 and 5.62 nA/cm2 of Ti and Ti64 respectively. Ti2448 adsorbed less protein as compared to Ti and Ti64 though no notable difference in surface wettability was observed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biocompatibility" title="biocompatibility">biocompatibility</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoblast" title=" osteoblast"> osteoblast</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20wettability" title=" surface wettability"> surface wettability</a>, <a href="https://publications.waset.org/abstracts/search?q=protein%20adsorption" title=" protein adsorption"> protein adsorption</a> </p> <a href="https://publications.waset.org/abstracts/93233/biocompatibility-and-electrochemical-assessment-of-biomedical-ti-24nb-4zr-8sn-produced-by-spark-plasma-sintering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93233.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">222</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> Demographic Dividend and Creation of Human and Knowledge Capital in Liberal India: An Endogenous Growth Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arjun%20K.">Arjun K.</a>, <a href="https://publications.waset.org/abstracts/search?q=Arumugam%20Sankaran"> Arumugam Sankaran</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjay%20Kumar"> Sanjay Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mousumi%20%20Das"> Mousumi Das</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper analyses the existence of endogenous growth scenario emanating from the demographic dividend in India during the liberalization period starting from 1980. Demographic dividend creates a fertile ground for the cultivation of human and knowledge capitals contributing to technological progress which can be measured using total factor productivity. The relationship among total factor productivity, human and knowledge capitals are examined in an open endogenous framework for the period 1980-2016. The control variables such as foreign direct investment, trade openness, energy consumption are also employed. The data are sourced from Reserve Bank of India, World Bank, International Energy Agency and The National Science and Technology Management Information System. To understand the dynamic association among variables, ARDL bounds approach to cointegration followed by Toda-Yamamoto causality test are used. The results reveal a short run and long run relationship among the variables supported by the existence of causality.

In previous study, joint stiffness was observed able to describe certain issues regarding to movement performance. But, correlation between balance ability and joint stiffness is still remains unknown. In this study, joint stiffening strategy at ankle and hip were observed under different sensory manipulations and its correlation with conventional clinical test (Functional Reach Test) for balance ability was investigated. In order to create unstable condition, two different surface perturbations (tilt up-tilt (TT) down and forward-backward (FB)) at four different frequencies (0.2, 0.4, 0.6 and 0.8 Hz) were introduced. Furthermore, four different sensory manipulation conditions (include vision and vestibular system) were applied to the subject and they were asked to maintain their position as possible. The results suggested that joint stiffness were high during difficult balance situation. Less balance people generated high average joint stiffness compared to balance people. Besides, adaptation of posture control system under repetitive external perturbation also suggested less during sensory limited condition. Overall, analysis of joint stiffening response possible to predict unbalance situation faced by human. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=balance%20ability" title="balance ability">balance ability</a>, <a href="https://publications.waset.org/abstracts/search?q=joint%20stiffness" title=" joint stiffness"> joint stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=sensory" title=" sensory"> sensory</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptation" title=" adaptation"> adaptation</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic" title=" dynamic"> dynamic</a> </p> <a href="https://publications.waset.org/abstracts/11595/effect-of-sensory-manipulations-on-human-joint-stiffness-strategy-and-its-adaptation-for-human-dynamic-stability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11595.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">459</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> Prosocial Behavior and Satisfaction with School Life in Elementary Children: From the Perspective of Classroom Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Takuma%20Yamamoto">Takuma Yamamoto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Present study investigated the relationship between elementary school children’s prosocial behavior in classroom and satisfaction with school life (approval and victimization from other children) with considering from the perspective of classroom social goal structures (prosocial and compliance goal structures). Participants were 755 elementary school children (393 boys, 362 girls, mean range= 10-12, 5th grader and 6th grader) who were living in Chugoku District, Japan. They filled up questionnaire which was consisted of Murakami, Nishimura and Sakurai’s (2016) prosocial behavior toward friend scale, Kawamura and Tagami’s (1997) satisfaction in classroom scale and Ohtani, Okada, Nakaya and Ito’s (2016) classroom social goal structures scale. Regression lines that satisfaction in classroom is dependent variable and prosocial behavior is independent variable for each class were drawn. There were two types of classroom which children’s prosocial behavior correlated with satisfaction positively and did not. Then one-way MANOVA was conducted to further describe two types of classroom which prosocial behavior increased satisfaction in classroom (type 1) and prosocial behavior decreased satisfaction (type 2). MANOVA for Prosocial goal structure was significant, type 1 > type 2. There were two key findings from this study. First, MANOVA for prosocial goal structure was significant. Second, high score of prosocial goal structure was not necessary condition for the classroom type which children’s prosocial behavior correlated with satisfaction. The implications from these key findings were: (1) in the low prosocial goal structure classroom, children will not behave prosocially because of their negative expectation for the effect of prosocial behavior, (2) this study can be a contribution for classroom management that teachers need to consider about the negative possibilities of prosocial behavior when they try to increase the amount of children’s positive behavior. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=elementary%20school%20children" title="elementary school children">elementary school children</a>, <a href="https://publications.waset.org/abstracts/search?q=classroom%20social%20goal%20structure" title=" classroom social goal structure"> classroom social goal structure</a>, <a href="https://publications.waset.org/abstracts/search?q=satisfaction%20with%20school%20life" title=" satisfaction with school life"> satisfaction with school life</a>, <a href="https://publications.waset.org/abstracts/search?q=prosocial%20behavior" title=" prosocial behavior"> prosocial behavior</a> </p> <a href="https://publications.waset.org/abstracts/101021/prosocial-behavior-and-satisfaction-with-school-life-in-elementary-children-from-the-perspective-of-classroom-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101021.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">245</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> Towards a Sustainable Energy Future: Method Used in Existing Buildings to Implement Sustainable Energy Technologies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Georgi%20Vendramin">Georgi Vendramin</a>, <a href="https://publications.waset.org/abstracts/search?q=Aurea%20L%C3%BAcia"> Aurea Lúcia</a>, <a href="https://publications.waset.org/abstracts/search?q=Yamamoto"> Yamamoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Itsuo"> Carlos Itsuo</a>, <a href="https://publications.waset.org/abstracts/search?q=Souza%20Melegari"> Souza Melegari</a>, <a href="https://publications.waset.org/abstracts/search?q=N.%20Samuel"> N.

The model is based on a healthy balance equations purely theoretical and empirical data. Simplified equations are derived through a synthesis of the measured data obtained from meteorological stations. The implementation of the model in a design tool integrated buildings is discussed in this article, to better punctuate the requirements of comfort and energy efficiency in architecture and engineering. Sustainability, energy efficiency, and the integration of alternative energy systems and concepts are beginning to be incorporated into designs for new buildings and renovations to existing buildings. Few means have existed to effectively validate the potential performance benefits of the design concepts. It was used a method of degree-days for an assessment of the energy performance of a building showed that the design of the architectural design should always be considered the materials used and the size of the openings. The energy performance was obtained through the model, considering the location of the building Central Park Shopping Mall, in the city of Cascavel - PR. Obtained climatic data of these locations and in a second step, it was obtained the coefficient of total heat loss in the building pre-established so evaluating the thermal comfort and energy performance. This means that the more openings in buildings in Cascavel – PR, installed to the east side, they may be higher because the glass added to the geometry of architectural spaces will cause the environment conserve energy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainable%20design" title="sustainable design">sustainable design</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20modeling" title=" energy modeling"> energy modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20validation" title=" design validation"> design validation</a>, <a href="https://publications.waset.org/abstracts/search?q=degree-days%20methods" title=" degree-days methods"> degree-days methods</a> </p> <a href="https://publications.waset.org/abstracts/11925/towards-a-sustainable-energy-future-method-used-in-existing-buildings-to-implement-sustainable-energy-technologies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11925.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">419</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Allele Mining for Rice Sheath Blight Resistance by Whole-Genome Association Mapping in a Tail-End Population</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naoki%20Yamamoto">Naoki Yamamoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Hidenobu%20Ozaki"> Hidenobu Ozaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Taiichiro%20Ookawa"> Taiichiro Ookawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Youming%20Liu"> Youming Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Kazunori%20Okada"> Kazunori Okada</a>, <a href="https://publications.waset.org/abstracts/search?q=Aiping%20Zheng"> Aiping Zheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rice sheath blight is one of the destructive fungal diseases in rice. We have thought that rice sheath blight resistance is a polygenic trait. Host-pathogen interactions and secondary metabolites such as lignin and phytoalexins are likely to be involved in defense against R. solani. However, to our knowledge, it is still unknown how sheath blight resistance can be enhanced in rice breeding. To seek for an alternative genetic factor that contribute to sheath blight resistance, we mined relevant allelic variations from rice core collections created in Japan. Based on disease lesion length on detached leaf sheath, we selected 30 varieties of the top tail-end and the bottom tail-end, respectively, from the core collections to perform genome-wide association mapping. Re-sequencing reads for these varieties were used for calling single nucleotide polymorphisms among the 60 varieties to create a SNP panel, which contained 1,137,131 homozygous variant sites after filitering. Association mapping highlighted a locus on the long arm of chromosome 11, which is co-localized with three sheath blight QTLs, qShB11-2-TX, qShB11, and qSBR-11-2. Based on the localization of the trait-associated alleles, we identified an ankyryn repeat-containing protein gene (ANK-M) as an uncharacterized candidate factor for rice sheath blight resistance. Allelic distributions for ANK-M in the whole rice population supported the reliability of trait-allele associations. Gene expression characteristics were checked to evaluiate the functionality of ANK-M. Since an ANK-M homolog (OsPIANK1) in rice seems a basal defense regulator against rice blast and bacterial leaf blight, ANK-M may also play a role in the rice immune system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=allele%20mining" title="allele mining">allele mining</a>, <a href="https://publications.waset.org/abstracts/search?q=GWAS" title=" GWAS"> GWAS</a>, <a href="https://publications.waset.org/abstracts/search?q=QTL" title=" QTL"> QTL</a>, <a href="https://publications.waset.org/abstracts/search?q=rice%20sheath%20blight" title=" rice sheath blight"> rice sheath blight</a> </p> <a href="https://publications.waset.org/abstracts/163885/allele-mining-for-rice-sheath-blight-resistance-by-whole-genome-association-mapping-in-a-tail-end-population" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163885.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">79</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> How Children Synchronize with Their Teacher: Evidence from a Real-World Elementary School Classroom</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reiko%20Yamamoto">Reiko Yamamoto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper reports on how synchrony occurs between children and their teacher, and what prevents or facilitates synchrony. The aim of the experiment conducted in this study was to precisely analyze their movements and synchrony and reveal the process of synchrony in a real-world classroom. Specifically, the experiment was conducted for around 20 minutes during an English as a foreign language (EFL) lesson. The participants were 11 fourth-grade school children and their classroom teacher in a public elementary school in Japan. Previous researchers assert that synchrony causes the state of flow in a class. For checking the level of flow, Short Flow State Scale (SFSS) was adopted. The experimental procedure had four steps: 1) The teacher read aloud the first half of an English storybook to the children. Both the teacher and the children were at their own desks. 2) The children were subjected to an SFSS check. 3) The teacher read aloud the remaining half of the storybook to the children. She made the children remove their desks before reading. 4) The children were again subjected to an SFSS check. The movements of all participants were recorded with a video camera. From the movement analysis, it was found that the children synchronized better with the teacher in Step 3 than in Step 1, and that the teacher’s movement became free and outstanding without a desk. This implies that the desk acted as a barrier between the children and the teacher. Removal of this barrier resulted in the children’s reactions becoming synchronized with those of the teacher. The SFSS results proved that the children experienced more flow without a barrier than with a barrier. Apparently, synchrony is what caused flow or social emotions in the classroom. The main conclusion is that synchrony leads to cognitive outcomes such as children’s academic performance in EFL learning. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=engagement%20in%20a%20class" title="engagement in a class">engagement in a class</a>, <a href="https://publications.waset.org/abstracts/search?q=English%20as%20a%20foreign%20language%20%28EFL%29%20learning" title=" English as a foreign language (EFL) learning"> English as a foreign language (EFL) learning</a>, <a href="https://publications.waset.org/abstracts/search?q=interactional%20synchrony" title=" interactional synchrony"> interactional synchrony</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20emotions" title=" social emotions"> social emotions</a> </p> <a href="https://publications.waset.org/abstracts/101358/how-children-synchronize-with-their-teacher-evidence-from-a-real-world-elementary-school-classroom" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101358.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">13</span> Comparison of the Indocyanine Green Dye Method versus the Combined Method of Indigo Carmine Blue Dye with Indocyanine Green Fluorescence Imaging for Sentinel Lymph Node Biopsy in Breast Conservative Therapy for Early Breast Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nobuyuki%20Takemoto">Nobuyuki Takemoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Ai%20Koyanagi"> Ai Koyanagi</a>, <a href="https://publications.waset.org/abstracts/search?q=Masanori%20Yasuda"> Masanori Yasuda</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Yamamoto"> Hiroshi Yamamoto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Fluorescence imaging (FI) is one of the methods to identify sentinel lymph nodes (SLNs). However, the procedure is technically complicated and requires procedural skills, as SLN biopsy must be conducted in dim light conditions. As an improved version of this method, we introduced a combined method (Combined mixed dye and fluorescence; CMF) consisting of indigo carmine blue dye and FI. The direct visualization of SLNs under shadowless surgical light conditions is facilitated by the addition of the blue dye. We compared the SLN detection rates of CMF with that of the indocyanine green (ICG) dye method (ICG-D). Methods: A total of 202 patients with stage ≤ IIA breast cancer who underwent breast conservative therapy with separate incision from January 2004 to February 2017 were reviewed. Details of the two methods are as follows: (1) ICG-D: 2ml of ICG (10mg) was used and the green-stained SLNs were resected via a 3-4cm axillary incision; (2) CMF: A combination of 1ml of ICG (5mg) and 1-3ml of indigo carmine (4-12mg) was used. Using Photodynamic Eye (PDE), a 1.5-2 cm incision was made near the point of disappearance of the fluorescence and SLNs with intermediate color of blue and green were resected. Results: There were 92 ICG-D and 110 CMF cases. CMF resulted in a significantly higher detection rate than ICG-D (96.4% vs. 83.7%; p=0.003). This difference was particularly notable in those aged ≥ 60 years (98.3% vs. 74.3%) and individuals with BMI ≥ 25kg/m2 (90.3% vs. 58.3%). Conclusion: CMF is an effective method to identify SLNs which is safe, efficient, and cost-effective. Furthermore, radiation exposure can be avoided, and it can be performed in institutes without nuclear medicine facilities. CMF achieves a high SLN identification rate, and most of this procedure is feasible under shadowless surgical light conditions. CMF can reliably perform SLN biopsy even in those aged ≥ 60 years and individuals with BMI ≥ 25 kg/m2. <p class="card-text"><strong>Keywords:</strong> <a
