aimed at the development of polyhydroxyalkanoates (PHAs) from micro-algae. These biobased and biodegradable polymers are being tested and validated in different high-volume market applications including food packaging, cosmetic packaging, 3D printing filaments, agro-textiles and medical devices, counting on the support of key players like Danone, BEL Group, Sofradim or IFG. At the moment the project has achieved to produce PHAs from micro-algae with a cumulated yield around 17%, i.e. 1 kg PHAs produced from 5.8 kg micro-algae biomass, which in turn capture 11 kg CO₂ for growing up. These algae-based plastics can therefore offer the same environmental benefits than current bio-based plastics (reduction of greenhouse gas emissions and fossil resource depletion), using a 3rd generation biomass feedstock that avoids the competition with food and the environmental impacts of agricultural practices. The project is also dealing with other sustainability aspects like the ecodesign and life cycle assessment of the plastic products targeted, considering not only the use of the biobased plastics but also many other ecodesign strategies. This paper will present the main progresses and results achieved to date in the project. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NENU2PHAR" title="NENU2PHAR">NENU2PHAR</a>, <a href="https://publications.waset.org/abstracts/search?q=Polyhydroxyalkanoates" title=" Polyhydroxyalkanoates"> Polyhydroxyalkanoates</a>, <a href="https://publications.waset.org/abstracts/search?q=micro-algae" title=" micro-algae"> micro-algae</a>, <a href="https://publications.waset.org/abstracts/search?q=biopolymer" title=" biopolymer"> biopolymer</a>, <a href="https://publications.waset.org/abstracts/search?q=ecodesign" title=" ecodesign"> ecodesign</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20assessment" title=" life cycle assessment"> life cycle assessment</a> </p> <a href="https://publications.waset.org/abstracts/157868/nenu2phar-pha-based-materials-from-micro-algae-for-high-volume-consumer-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157868.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">90</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">46</span> Development of a Tesla Music Coil from Signal Processing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samaniego%20Campoverde%20Jos%C3%A9%20Enrique">Samaniego Campoverde José Enrique</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosero%20Mu%C3%B1oz%20Jorge%20Enrique"> Rosero Muñoz Jorge Enrique</a>, <a href="https://publications.waset.org/abstracts/search?q=Luzcando%20Narea%20Lorena%20Elizabeth"> Luzcando Narea Lorena Elizabeth</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a practical and theoretical model for the operation of the Tesla coil using digital signal processing.

These spring elements are equipped with constitutive models to include independently the moment, shear force and axial force, respectively. These constitutive models are formulated based on damage mechanics and experimental test reported in the literature review. The mesh of the segmented tunnels was discretized in the software GID, and the nonlinear analyses were carried out in the finite element software ANSYS. These analyses provide the capacity curve of the primary and secondary lining of a segmented tunnel. Two numerical examples of segmented tunnels show the capability of the spring elements to release energy by the development of hinges. The first example is a segmental concrete lining discretized with frame elements loaded until hinges occurred in the lining. The second example is a tunnel with primary and secondary lining, discretized with a double ring frame model. The outer ring simulates the segmental concrete lining and the inner ring simulates the secondary cast-in-place concrete lining. Spring elements also modelled the joints between the segments in the circumferential direction and the ring joints, which connect parallel adjacent rings. The computed load vs displacement curves are congruent with numerical and experimental results reported in the literature review. It is shown that the modelling of a tunnel with primary and secondary lining with frame elements and springs provides reasonable results and save computational cost, comparing with 2D or 3D models equipped with smeared crack models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damage" title="damage">damage</a>, <a href="https://publications.waset.org/abstracts/search?q=hinges" title=" hinges"> hinges</a>, <a href="https://publications.waset.org/abstracts/search?q=lining" title=" lining"> lining</a>, <a href="https://publications.waset.org/abstracts/search?q=tunnel" title=" tunnel"> tunnel</a> </p> <a href="https://publications.waset.org/abstracts/56714/modelling-of-damage-as-hinges-in-segmented-tunnels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56714.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">390</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">43</span> Virtual Science Hub: An Open Source Platform to Enrich Science Teaching</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Barra">Enrique Barra</a>, <a href="https://publications.waset.org/abstracts/search?q=Aldo%20Gordillo"> Aldo Gordillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Quemada"> Juan Quemada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the Virtual Science Hub platform.

To compare these techniques we use a cost functional that minimize the wild-type virus population and the mutant virus population, but the main objective is to minimize the systemic cost of treatment and maximize levels of healthy CD4+ T cells. HyOOC, HOOC, and sSTI are applied to the drug therapies using a reverse transcriptase and protease inhibitors; simulations show that these controls maintain the uninfected cells in a small, bounded neighborhood of a pre-specified level.

Although usually referred to as ”lotteries”, there is evidence that some national teams and clubs consistently perform better than others. The outcomes are therefore not explained just by mere luck, and therefore there are ways to improve the average performance of players, naturally at the expense of some sort of effort. In this article we study the payoff of player performance improvements in terms of the performance of the team as a whole. To do so we develop an analytical model with static individual performances, as well as Monte Carlo models that take into account the known influence of partial score and round number on individual performances. We find that within a range of usual values, the team performance improves above 70% faster than individual performances do. Using these models, we also estimate that the new ABBA penalty shootout ordering under test reduces almost all the known bias in favor of the first-shooting team under the current ABAB system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=football" title="football">football</a>, <a href="https://publications.waset.org/abstracts/search?q=penalty%20shootouts" title=" penalty shootouts"> penalty shootouts</a>, <a href="https://publications.waset.org/abstracts/search?q=Montecarlo%20simulation" title=" Montecarlo simulation"> Montecarlo simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=ABBA" title=" ABBA"> ABBA</a> </p> <a href="https://publications.waset.org/abstracts/104452/modeling-football-penalty-shootouts-how-improving-individual-performance-affects-team-performance-and-the-fairness-of-the-abab-sequence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104452.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">162</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">34</span> Comparison of Two Fuzzy Skyhook Control Strategies Applied to an Active Suspension</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reginaldo%20Cardoso">Reginaldo Cardoso</a>, <a href="https://publications.waset.org/abstracts/search?q=Magno%20Enrique%20Mendoza%20Meza"> Magno Enrique Mendoza Meza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work focuses on simulation and comparison of two control skyhook techniques applied to a quarter-car of the active suspension. The objective is to provide comfort to the driver. The main idea of skyhook control is to imagine a damper connected to an imaginary sky; thus, the feedback is performed with the resultant force between the imaginary and the suspension damper. The first control technique is the Mandani fuzzy skyhook and the second control technique is a Takagi-Sugeno fuzzy skyhook controller, in the both controllers the inputs are the relative velocity between the two masses and the vehicle body velocity, the output of the Mandani fuzzy skyhook is the coefficient of imaginary damper viscous-friction and the Takagi-Sugeno fuzzy skyhook is the force. Finally, we compared the techniques. The Mandani fuzzy skyhook showed a more comfortable response to the driver, followed closely by the Takagi- Sugeno fuzzy skyhook. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20suspention" title="active suspention">active suspention</a>, <a href="https://publications.waset.org/abstracts/search?q=Mandani" title=" Mandani"> Mandani</a>, <a href="https://publications.waset.org/abstracts/search?q=quarter-car" title=" quarter-car"> quarter-car</a>, <a href="https://publications.waset.org/abstracts/search?q=skyhook" title=" skyhook"> skyhook</a>, <a href="https://publications.waset.org/abstracts/search?q=Sugeno" title=" Sugeno"> Sugeno</a> </p> <a href="https://publications.waset.org/abstracts/32492/comparison-of-two-fuzzy-skyhook-control-strategies-applied-to-an-active-suspension" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32492.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">463</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">33</span> Application of Sensory Thermography on Workers of a Wireless Industry in Mexico</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Camargo%20Wilson">Claudia Camargo Wilson</a>, <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Javier%20de%20la%20Vega%20Bustillos"> Enrique Javier de la Vega Bustillos</a>, <a href="https://publications.waset.org/abstracts/search?q=Jes%C3%BAs%20Everardo%20Olgu%C3%ADn%20Tiznado"> Jesús Everardo Olguín Tiznado</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Andr%C3%A9s%20L%C3%B3pez%20Barreras"> Juan Andrés López Barreras</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20K.%20Enriquez"> Sandra K.

Six sites inside the tropical Terminos Lagoon were sampled in order to determine abundances and ecological indexes for phytoplankton from May to December 2017. Water samples were also collected to determine the values of pigments, nutrients, and water solids. Results showed that the composition and abundance of the phytoplankton community were influenced by physicochemical factors, nutrients, water solids, and climate seasons. Sixty-six species were identified as potential HAB producers (44.29% from total). However, abundances were not related to the occurrence of HAB during the study. Multidimensional ANOVA indicated no significant differences between sites while some months revealed significant differences. The canonical analysis suggested that environmental variables explained 49% of community variation of potential phytoplankton species producers of HAB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phytoplankton" title="phytoplankton">phytoplankton</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=lagoon" title=" lagoon"> lagoon</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title=" biodiversity"> biodiversity</a> </p> <a href="https://publications.waset.org/abstracts/122868/phytoplankton-community-composition-in-laguna-de-terminos-mexico-and-its-relationship-to-environmental-variables" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122868.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">138</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31</span> Soil-Structure Interaction in Stiffness and Strength Degrading Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Bazan-Zurita">Enrique Bazan-Zurita</a>, <a href="https://publications.waset.org/abstracts/search?q=Sittipong%20Jarernprasert"> Sittipong Jarernprasert</a>, <a href="https://publications.waset.org/abstracts/search?q=Jacobo%20Bielak"> Jacobo Bielak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We study the effects of soil-structure interaction (SSI) on the inelastic seismic response of a single-degree-of-freedom system whose hysteretic behaviour exhibits stiffness and/or strength degrading characteristics. Two sets of accelerograms are used as seismic input: the first comprising 87 record from stiff to medium stiff sites in California, and the second comprising 66 records from the soft lakebed of Mexico City. This study focuses in three seismic response parameters: ductility demand, inter-story drift, and total lateral displacement. The results allow quantitative estimates of changes in such parameters in an SSI system in comparison with those corresponding to the associated fixed-base system. We found that degrading features affect significantly both the response of fixed-base structures and the impact of soil-structure interaction. We propose a procedure to incorporate the results of this and similar studies in seismic design regulations for SSI system with anticipated nonlinear degrading behaviour. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inelastic" title="inelastic">inelastic</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic" title=" seismic"> seismic</a>, <a href="https://publications.waset.org/abstracts/search?q=building" title=" building"> building</a>, <a href="https://publications.waset.org/abstracts/search?q=foundation" title=" foundation"> foundation</a>, <a href="https://publications.waset.org/abstracts/search?q=interaction" title=" interaction"> interaction</a> </p> <a href="https://publications.waset.org/abstracts/7045/soil-structure-interaction-in-stiffness-and-strength-degrading-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7045.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">286</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 Filipino Catholics in Japan: Traces and Cues of De/Ghettoization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Willard%20Enrique%20R.%20Macaraan">Willard Enrique R.

This paper aims to uncover the nuances of this marginality by utilizing Loic Wacquant's theorization of urban ghettos as well as Pierre Bourdieu's field ideation. In an attempt to illustrate the dynamics of the power-play that is implicit in any situation of marginality, the paper proposes a 'diamond-quadrant' (DQ) plane that may serve as a heuristic device for analytical purposes. This study is drawn from data collected and gathered through ten-month field research in selected church communities in the Archdiocese of Tokyo, Japan employing qualitative methodologies like participant observation, interviews, and document reviews. Reconstructing their historicized struggle since the late 70s, it is discovered that the arena of contested space has shifted from the right plane of "ghettoization" tendencies in the early years towards the left plane of "deghettoization" strategies in recent years. Still, a highly negotiated space, several situational factors, and emerging trends in and outside the ecclesial grounds have led to this major shift. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wacquant" title="Wacquant">Wacquant</a>, <a href="https://publications.waset.org/abstracts/search?q=ghetto" title=" ghetto"> ghetto</a>, <a href="https://publications.waset.org/abstracts/search?q=migration" title=" migration"> migration</a>, <a href="https://publications.waset.org/abstracts/search?q=religion" title=" religion"> religion</a> </p> <a href="https://publications.waset.org/abstracts/151055/the-filipino-catholics-in-japan-traces-and-cues-of-deghettoization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151055.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">93</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> Aquatic and Marshy Flora from Fresh Water Wetlands on Quartz Sands in Pinar Del Río, Cuba</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vidal%20P%C3%A9rez%20Hern%C3%A1ndez">Vidal Pérez Hernández</a>, <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Gonz%C3%A1lez%20Pend%C3%A1s"> Enrique González Pendás</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The most of the aquatic and marshy flora in Cuba, is located on quartzitic sands ecosystems and they are represented by a wide variety of freshwater wetlands, which are spread in the whole south and south-western plain of Pinar del Río. The survey carried out in these ecosystems offers an updated inventory of these species, showing up their biological type, habit, distribution, and the threat grade to which are subjected, taking into account categories granted by UICN. A remarkable decrease is evidenced, in the total of these species respect to this area; due to deposit processes and deforestation, which are taken place by the human activity and the climatic change. It is linked to others threats like, limitless use of their water reserves for irrigating groves, the cattle raising and intensive fishing.

Heuristic mitigating action profiles of the pharmaceutical and non-pharmaceutical types may be developed in a control design setting for the purpose of reducing the transmission rate or improving the recovery rate parameters in the model. Even though the transmission and recovery rates are not control inputs in the traditional sense, a linear observer and feedback controller can be tuned to generate an asymptotic estimate of the transmission rate for a linearized, discrete-time version of the SIR model. Then, a set of mitigating actions is suggested to steer the basic reproduction number toward unity, in which case the disease does not spread, and the infected population state does not suffer from multiple waves. The special case of piecewise constant transmission rate is described and applied to a seventh-order SEIQRDP model, which segments the population into four additional states. The offline simulations in discrete time may be used to produce heuristic policies implemented by public health and government organizations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=control%20of%20SIR" title="control of SIR">control of SIR</a>, <a href="https://publications.waset.org/abstracts/search?q=observer" title=" observer"> observer</a>, <a href="https://publications.waset.org/abstracts/search?q=SEIQRDP" title=" SEIQRDP"> SEIQRDP</a>, <a href="https://publications.waset.org/abstracts/search?q=disease%20spread" title=" disease spread"> disease spread</a> </p> <a href="https://publications.waset.org/abstracts/167821/control-of-an-sir-model-for-basic-reproduction-number-regulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167821.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">110</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> Effect of Graphene Oxide Nanoparticles on a Heavy Oilfield: Interfacial Tension, Wettability and Oil Displacement Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jimena%20Lizeth%20Gomez%20Delgado">Jimena Lizeth Gomez Delgado</a>, <a href="https://publications.waset.org/abstracts/search?q=Jhon%20Jairo%20Rodriguez"> Jhon Jairo Rodriguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Santos"> Nicolas Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Mejia%20Ospino"> Enrique Mejia Ospino</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nanotechnology has played an important role in the hydrocarbon industry, recently , due to the unique properties of graphene oxide nanoparticles, they have been incorporated in different studies enhanced oil recovery.

The performance of Graphene oxide nanoparticles on the interfacial properties in the presence of different electrolyte concentrations representative of field brine and pH conditions was investigated. Moreover, wettability behavior of the nanofluid at the oil/sand interface was studied used contact angle and Amott Harvey evaluation.

Studies have shown that C-devices made of mild steel can be successfully applied as integral parts of seismic retrofitting schemes. However, explicit modelling of these devices can become cumbersome, expensive and time consuming. The device under study in this article has been previously used in non-invasive dissipative bracing for seismic retrofitting. The device is cut from a mild steel plate and has an overall shape that resembles that of a rectangular portal frame with circular interior corner transitions to avoid stress concentration and to control the extension of the dissipative region of the device. A number of inelastic finite element (FE) analyses using either inelastic 2D plane stress elements or inelastic fibre frame elements are reported and used to calibrate a 1D equivalent inelastic spring model that effectively reproduces the cyclic response of the device. The more elaborate FE model accounts for the frictional forces developed between the steel plate and the bolts used to connect the C-device to structural members. FE results also allow the visualization of the inelastic regions of the device where energy dissipation is expected to occur. FE analysis results are in a good agreement with experimental observations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=C-device" title="C-device">C-device</a>, <a href="https://publications.waset.org/abstracts/search?q=equivalent%20nonlinear%20spring" title=" equivalent nonlinear spring"> equivalent nonlinear spring</a>, <a href="https://publications.waset.org/abstracts/search?q=FE%20analyses" title=" FE analyses"> FE analyses</a>, <a href="https://publications.waset.org/abstracts/search?q=reversed%20cyclic%20tests" title=" reversed cyclic tests"> reversed cyclic tests</a> </p> <a href="https://publications.waset.org/abstracts/95702/development-of-equivalent-inelastic-springs-to-model-c-devices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95702.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Seismic Directionality Effects on In-Structure Response Spectra in Seismic Probabilistic Risk Assessment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sittipong%20Jarernprasert">Sittipong Jarernprasert</a>, <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Bazan-Zurita"> Enrique Bazan-Zurita</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20C.%20Rizzo"> Paul C. Rizzo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Currently, seismic probabilistic risk assessments (SPRA) for nuclear facilities use In-Structure Response Spectra (ISRS) in the calculation of fragilities for systems and components. ISRS are calculated via dynamic analyses of the host building subjected to two orthogonal components of horizontal ground motion. Each component is defined as the median motion in any horizontal direction. Structural engineers applied the components along selected X and Y Cartesian axes. The ISRS at different locations in the building are also calculated in the X and Y directions. The choice of the directions of X and Y are not specified by the ground motion model with respect to geographic coordinates, and are rather arbitrarily selected by the structural engineer. Normally, X and Y coincide with the “principal” axes of the building, in the understanding that this practice is generally conservative. For SPRA purposes, however, it is desirable to remove any conservatism in the estimates of median ISRS. This paper examines the effects of the direction of horizontal seismic motion on the ISRS on typical nuclear structure. We also evaluate the variability of ISRS calculated along different horizontal directions. Our results indicate that some central measures of the ISRS provide robust estimates that are practically independent of the selection of the directions of the horizontal Cartesian axes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seismic" title="seismic">seismic</a>, <a href="https://publications.waset.org/abstracts/search?q=directionality" title=" directionality"> directionality</a>, <a href="https://publications.waset.org/abstracts/search?q=in-structure%20response%20spectra" title=" in-structure response spectra"> in-structure response spectra</a>, <a href="https://publications.waset.org/abstracts/search?q=probabilistic%20risk%20assessment" title=" probabilistic risk assessment"> probabilistic risk assessment</a> </p> <a href="https://publications.waset.org/abstracts/18572/seismic-directionality-effects-on-in-structure-response-spectra-in-seismic-probabilistic-risk-assessment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18572.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">410</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> Antiproliferative Effect of Polyphenols from Crocus sativus L.

This is in contrast to other underutilized parts of the saffron plant as leaves, which represent abundant biomass whose use might help to enhance the sustainability of the saffron crop. Saffron leaves contain significant amounts of phenolic compounds, 7.8 equivalent grams of gallic acid per 100g of extract, and are very promising compounds in terms of exploring novel uses of saffron leaves. Given that phenolic compounds have numerous effects on cancer-related biological pathways, we have investigated the in vitro antiproliferative effect of saffron leaf polyphenols against human colon adenocarcinoma cells (Caco-2). Polyphenols were extracted from leaves with 70% ethanol, defatted with hexane, and purified by solid phase extraction using C18 silica gel and then silica gel 60. Analysis of polyphenols was performed by HPLC-ESI-MS. Di-, tri-, and tetrahexosides of quercetin, kaempferol, and isorhamnetin, as well as C-hexosides like isoorientin and vitexin, were tentatively identified. Polyphenols strongly inhibited the proliferation of Caco-2 cells, which is consistent with model studies in which several of the polyphenols identified in saffron leaves have demonstrated their potential as chemopreventive agents in cancer. Due to the low profitability that saffron leaf currently represents, we consider these results very encouraging and that this by-product deserves further investigation as a potential source of active molecules against colorectal cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=saffron%20leaves" title="saffron leaves">saffron leaves</a>, <a href="https://publications.waset.org/abstracts/search?q=agricultural%20by-products" title=" agricultural by-products"> agricultural by-products</a>, <a href="https://publications.waset.org/abstracts/search?q=polyphenols" title=" polyphenols"> polyphenols</a>, <a href="https://publications.waset.org/abstracts/search?q=antiproliferative%20effect" title=" antiproliferative effect"> antiproliferative effect</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20colon%20adenocarcinoma%20cells" title=" human colon adenocarcinoma cells"> human colon adenocarcinoma cells</a> </p> <a href="https://publications.waset.org/abstracts/141891/antiproliferative-effect-of-polyphenols-from-crocus-sativus-l-leaves-on-human-colon-adenocarcinoma-cells-caco-2" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141891.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">94</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> Viscoelastic Properties of Sn-15%Pb Measured in an Oscillation Test </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gerardo%20Sanjuan%20Sanjuan">Gerardo Sanjuan Sanjuan</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%81ngel%20Enrique%20Chav%C3%A9z%20Castellanos"> Ángel Enrique Chavéz Castellanos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The knowledge of the rheological behavior of partially solidified metal alloy is an important issue when modeling and simulation of die filling in semisolid processes. Many experiments for like steady state, the step change in shear rate tests, shear stress ramps have been carried out leading that semi-solid alloys exhibit shear thinning, thixotropic behavior and yield stress. More advanced investigation gives evidence some viscoelastic features can be observed. The viscoelastic properties of materials are determinate by transient or dynamic methods; unfortunately, sparse information exists about oscillation experiments. The aim of this present work is to use small amplitude oscillatory tests for knowledge properties such as G´ and G´´. These properties allow providing information about materials structure. For this purpose, we investigated tin-lead alloy (Sn-15%Pb) which exhibits a similar microstructure to aluminum alloys and is the classic alloy for semisolid thixotropic studies. The experiments were performed with parallel plates rheometer AR-G2. Initially, the liquid alloy is cooled down to the semisolid range, a specific temperature to guarantee a constant fraction solid. Oscillation was performed within the linear viscoelastic regime with a strain sweep. So, the loss modulus G´´, the storage modulus G´ and the loss angle (δ) was monitored. In addition a frequency sweep at a strain below the critical strain for characterized its structure. This provides more information about the interactions among solid particles on a liquid matrix. After testing, the sample was removed then cooled, sectioned and examined metallographically. These experiments demonstrate that the viscoelasticity is sensitive to the solid fraction, and is strongly influenced by the shape and size of particles solid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rheology" title="rheology">rheology</a>, <a href="https://publications.waset.org/abstracts/search?q=semisolid%20alloys" title=" semisolid alloys"> semisolid alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=thixotropic" title=" thixotropic"> thixotropic</a>, <a href="https://publications.waset.org/abstracts/search?q=viscoelasticity" title=" viscoelasticity"> viscoelasticity</a> </p> <a href="https://publications.waset.org/abstracts/32253/viscoelastic-properties-of-sn-15pb-measured-in-an-oscillation-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32253.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">376</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> An Investigation into the Ideological Facets Involved in Western Interpretations of the History of Communism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Stoutenburg">Anna Stoutenburg</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the rise of the so-called 'new left' within the United States, marked by social democratic figures such as Bernie Sanders and Alexandria Ocasio-Cortez, significant questions have been raised in response to those who would identify with the term 'socialist'. These queries typically revolve around the negatively perceived legacy of past and present countries that share the term in question, with the stark conclusion that not only is socialism a structure that does not work economically, but that it also tends to inflict more harm on those living under it that would be endured in a country functioning under capitalism. In order to examine these claims, the goal of this paper is to examine the legacy of anti-communist historiography in a western context, with the Union of Soviet Socialist Republics, China, and modern Venezuela used as case studies for how this phenomenon operates. Not only will key portions of each nation’s history be re-examined, but there will also be a critical analysis of source cultivation and usage among western historians. The intent of this paper is not merely to deride previous attempts at historicizing and reporting on the events of the nations, but rather to attempt to glean a clearer picture that is free from anti-communist sentiments. Theoretical works that will be consulted in order to define this project are 'The Historiography of Communism' by Michael Brown, as well as 'Beyond Philosophy: Ethics, History, Marxism, and Liberation Theology' by Enrique Dussel. The latter will provide insights concerning why these questions are relevant in a larger context, namely by articulating how the means of liberation understood through an analectic method can be achieved structurally. For a majority of leftists, this question is integral, and by using history as a tool, the ways that political organizing can be used can be better understood, bridging the gap between the common assumption that the communist legacy is a dire one and the idea that it is something which needs to be completely lauded. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-communism" title="anti-communism">anti-communism</a>, <a href="https://publications.waset.org/abstracts/search?q=history" title=" history"> history</a>, <a href="https://publications.waset.org/abstracts/search?q=ideology" title=" ideology"> ideology</a>, <a href="https://publications.waset.org/abstracts/search?q=Marxism" title=" Marxism"> Marxism</a> </p> <a href="https://publications.waset.org/abstracts/108621/an-investigation-into-the-ideological-facets-involved-in-western-interpretations-of-the-history-of-communism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108621.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">123</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> A Literature Review on the Effect of Industrial Clusters and the Absorptive Capacity on Innovation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Claver%20Cort%C3%A9s">Enrique Claver Cortés</a>, <a href="https://publications.waset.org/abstracts/search?q=Bartolom%C3%A9%20Marco%20Lajara"> Bartolomé Marco Lajara</a>, <a href="https://publications.waset.org/abstracts/search?q=Eduardo%20S%C3%A1nchez%20Garc%C3%ADa"> Eduardo Sánchez García</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Seva%20Larrosa"> Pedro Seva Larrosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Encarnaci%C3%B3n%20Manresa%20Marhuenda"> Encarnación Manresa Marhuenda</a>, <a href="https://publications.waset.org/abstracts/search?q=Lorena%20Ruiz%20Fern%C3%A1ndez"> Lorena Ruiz Fernández</a>, <a href="https://publications.waset.org/abstracts/search?q=Esther%20Poveda%20Pareja"> Esther Poveda Pareja</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent decades, the analysis of the effects of clustering as an essential factor for the development of innovations and the competitiveness of enterprises has raised great interest in different areas. Nowadays, companies have access to almost all tangible and intangible resources located and/or developed in any country in the world. However, despite the obvious advantages that this situation entails for companies, their geographical location has shown itself, increasingly clearly, to be a fundamental factor that positively influences their innovative performance and competitiveness. Industrial clusters could represent a unique level of analysis, positioned between the individual company and the industry, which makes them an ideal unit of analysis to determine the effects derived from company membership of a cluster. Also, the absorptive capacity (hereinafter 'AC') can mediate the process of innovation development by companies located in a cluster. The transformation and exploitation of knowledge could have a mediating effect between knowledge acquisition and innovative performance. The main objective of this work is to determine the key factors that affect the degree of generation and use of knowledge from the environment by companies and, consequently, their innovative performance and competitiveness. The elements analyzed are the companies' membership of a cluster and the AC. To this end, 30 most relevant papers published on this subject in the "Web of Science" database have been reviewed. Our findings show that, within a cluster, the knowledge coming from the companies' environment can significantly influence their innovative performance and competitiveness, although in this relationship, the degree of access and exploitation of the companies to this knowledge plays a fundamental role, which depends on a series of elements both internal and external to the company. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absorptive%20capacity" title="absorptive capacity">absorptive capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=clusters" title=" clusters"> clusters</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation" title=" innovation"> innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge" title=" knowledge"> knowledge</a> </p> <a href="https://publications.waset.org/abstracts/122776/a-literature-review-on-the-effect-of-industrial-clusters-and-the-absorptive-capacity-on-innovation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122776.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">19</span> Linearly Polarized Single Photon Emission from Nonpolar, Semipolar and Polar Quantum Dots in GaN/InGaN Nanowires </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Snezana%20Lazic">Snezana Lazic</a>, <a href="https://publications.waset.org/abstracts/search?q=Zarko%20Gacevic"> Zarko Gacevic</a>, <a href="https://publications.waset.org/abstracts/search?q=Mark%20Holmes"> Mark Holmes</a>, <a href="https://publications.waset.org/abstracts/search?q=Ekaterina%20Chernysheva"> Ekaterina Chernysheva</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcus%20M%C3%BCller"> Marcus Müller</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Veit"> Peter Veit</a>, <a href="https://publications.waset.org/abstracts/search?q=Frank%20Bertram"> Frank Bertram</a>, <a href="https://publications.waset.org/abstracts/search?q=Juergen%20Christen"> Juergen Christen</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasuhiko%20Arakawa"> Yasuhiko Arakawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Calleja"> Enrique Calleja</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study reports how the pencil-like morphology of a homoepitaxially grown GaN nanowire can be exploited for the fabrication of a thin conformal InGaN nanoshell, hosting nonpolar, semipolar and polar single photon sources (SPSs). All three SPS types exhibit narrow emission lines (FWHM~0.35 - 2 meV) and high degrees of linear optical polarization (P > 70%) in the low-temperature micro-photoluminescence (µ-PL) experiments and are characterized by a pronounced antibunching in the photon correlation measurements (gcorrected(2)(0) < 0.3). The quantum-dot-like exciton localization centers induced by compositional fluctuations within the InGaN nanoshell are identified as the driving mechanism for the single photon emission. As confirmed by the low-temperature transmission electron microscopy combined with cathodoluminescence (TEM-CL) study, the crystal region (i.e. non-polar m-, semi-polar r- and polar c-facets) hosting the single photon emitters strongly affects their emission wavelength, which ranges from ultra-violet for the non-polar to visible for the polar SPSs. The photon emission lifetime is also found to be facet-dependent and varies from sub-nanosecond time scales for the non- and semi-polar SPSs to a few nanoseconds for the polar ones. These differences are mainly attributed to facet-dependent indium content and electric field distribution across the hosting InGaN nanoshell. The hereby reported pencil-like InGaN nanoshell is the first single nanostructure able to host all three types of single photon emitters and is thus a promising building block for tunable quantum light devices integrated into future photonic and optoelectronic circuits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GaN%20nanowire" title="GaN nanowire">GaN nanowire</a>, <a href="https://publications.waset.org/abstracts/search?q=InGaN%20nanoshell" title=" InGaN nanoshell"> InGaN nanoshell</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20polarization" title=" linear polarization"> linear polarization</a>, <a href="https://publications.waset.org/abstracts/search?q=nonpolar" title=" nonpolar"> nonpolar</a>, <a href="https://publications.waset.org/abstracts/search?q=semipolar" title=" semipolar"> semipolar</a>, <a href="https://publications.waset.org/abstracts/search?q=polar%20quantum%20dots" title=" polar quantum dots"> polar quantum dots</a>, <a href="https://publications.waset.org/abstracts/search?q=single-photon%20sources" title=" single-photon sources"> single-photon sources</a> </p> <a href="https://publications.waset.org/abstracts/69652/linearly-polarized-single-photon-emission-from-nonpolar-semipolar-and-polar-quantum-dots-in-ganingan-nanowires" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69652.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">392</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> An Empirical Study of the Moderation Effects of Commitment, Trust, and Relationship Value in the Relation of Goods and Services Related to Business to Business Brand Images on Customer Loyalty</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Luis%20Morales%20Romero">Jorge Luis Morales Romero</a>, <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Murillo%20Oth%C3%B3n"> Enrique Murillo Othón</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Business to business (B2B) relationships generally go beyond a purely profit-based result, with firms seeking to maintain a relationship for many years because a breakup or getting a new supplier can be very costly. Therefore, identifying the factors which determine a successful relationship in the long term is of great interest to companies. That is why their reputation and the brand image that customers have of them are among the main factors that can achieve a successful relationship; Because of the positive effect which is driven by the client’s loyalty. Additionally, the perception that a customer may have about a brand is different when it is related to goods or to services. Thereby, they create in their minds their own brand image of it based on the past experiences they have had; Thus, a positive relationship is established between goods-related brand image, service-related brand image, and customer loyalty. The present investigation examines the boundary conditions of said relationship by testing the moderating effects of trust, commitment, and relationship value in a B2B environment. All the variables were tested independently as moderators for service-related brand image/loyalty and for goods-related brand image/loyalty, as they are assumed to be separate variables. Survey data was collected through interviews with customers that have both a product-buying relationship and a service relationship with a global B2B brand of healthcare equipment operating in the Mexican healthcare market. Interviewed respondents were either the user or the purchasing manager and/or the responsible for the equipment maintenance for the customer organization. Hence, they were appropriate informants regarding the B2B relationship with this healthcare brand. The moderation models were estimated using the PROCESS macro for the Statistical Package for the Social Sciences Software (SPSS). Results show statistical evidence that both Relationship Value and Trust are significant moderators for the service-related brand image/loyalty relation but not significant for the goods-related brand/loyalty relation. On the other hand, Commitment results in a significant moderator for the goods-related brand/loyalty relation but is not significant for the service-related brand image/loyalty relation. <p
