</p> <p class="card-text"><strong>Abstract:</strong></p> Background: Although immune checkpoint inhibitors (ICIs) have changed the treatment paradigm of non–small cell lung cancer (NSCLC), these drugs fail to elicit durable responses in the majority of NSCLC patients. The gut microbiota, able to regulate immune responsiveness, is emerging as a promising, modifiable target to improve ICIs response rates. Since the oral microbiome has been demonstrated to be the primary source of bacterial microbiota in the lungs, we investigated its composition as a potential predictive biomarker to identify and select patients who could benefit from immunotherapy. Methods: Thirty-five patients with stage IV squamous and non-squamous cell NSCLC eligible for an anti-PD-1/PD-L1 as monotherapy were enrolled. Saliva samples were collected from patients prior to the start of treatment, bacterial DNA was extracted using the QIAamp® DNA Microbiome Kit (QIAGEN) and the 16S rRNA gene was sequenced on a MiSeq sequencing instrument (Illumina). Results: NSCLC patients were dichotomized as “Responders” (partial or complete response) and “Non-Responders” (progressive disease), after 12 weeks of treatment, based on RECIST criteria. A prevalence of the phylum Candidatus Saccharibacteria was found in the 10 responders compared to non-responders (abundance 5% vs 1% respectively; p-value = 1.46 x 10-7; False Discovery Rate (FDR) = 1.02 x 10-6). Moreover, a higher prevalence of Saccharibacteria Genera Incertae Sedis genus (belonging to the Candidatus Saccharibacteria phylum) was observed in "responders" (p-value = 6.01 x 10-7 and FDR = 2.46 x 10-5). Finally, the patients who benefit from immunotherapy showed a significant abundance of TM7 Phylum Sp Oral Clone FR058 strain, member of Saccharibacteria Genera Incertae Sedis genus (p-value = 6.13 x 10-7 and FDR=7.66 x 10-5). Conclusions: These preliminary results showed a significant association between oral microbiota and ICIs response in NSCLC patients. In particular, the higher prevalence of Candidatus Saccharibacteria phylum and TM7 Phylum Sp Oral Clone FR058 strain in responders suggests their potential immunomodulatory role. The study is still ongoing and updated data will be presented at the congress. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oral%20microbiota" title="oral microbiota">oral microbiota</a>, <a href="https://publications.waset.org/abstracts/search?q=immune%20checkpoint%20inhibitors" title=" immune checkpoint inhibitors"> immune checkpoint inhibitors</a>, <a href="https://publications.waset.org/abstracts/search?q=non-small%20cell%20lung%20cancer" title=" non-small cell lung cancer"> non-small cell lung cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=predictive%20biomarker" title=" predictive biomarker"> predictive biomarker</a> </p> <a href="https://publications.waset.org/abstracts/163788/oral-microbiota-as-a-novel-predictive-biomarker-of-response-to-immune-checkpoint-inhibitors-in-advanced-non-small-cell-lung-cancer-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163788.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">97</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">107</span> Extraction of Cellulose Nanocrystals from Soy Pods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maycon%20dos%20Santos">Maycon dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Marivane%20Turim%20Koschevic"> Marivane Turim Koschevic</a>, <a href="https://publications.waset.org/abstracts/search?q=Karina%20Sayuri%20Ueda"> Karina Sayuri Ueda</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcello%20Lima%20Bertuci"> Marcello Lima Bertuci</a>, <a href="https://publications.waset.org/abstracts/search?q=Farayde%20Matta%20Fackhouri"> Farayde Matta Fackhouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Maria%20Martelli"> Silvia Maria Martelli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of cellulose nanocrystals as reinforcing agents in polymer nanocomposites is promising.

These values and norms represent the organizational culture, which determines the behavior of the workers, guides the work practices and impacts the quality of care and the safety culture of health services worldwide. Objective: To analyze the organizational culture of a public and a private hospital in Brazil. Method: Descriptive study with quantitative approach developed in a public and in a private hospital of Brazil. Sample was composed by 281 nursing workers, of which 73 nurses and 208 nursing auxiliaries and technicians. The data collection instrument comprised the Brazilian Instrument for Assessing Organizational Culture. Data were collected from March to December 2013. Results: At the public hospital, the results showed an average score of 2.85 for the values concerning cooperative professionalism (CP); 3.02 for values related to hierarchical rigidity and the centralization of power (HR); 2.23 for individualistic professionalism and competition at work (IP); 2.22 for values related to satisfaction, well-being and motivation of workers (SW); 3.47 for external integration (EI); 2.03 for rewarding and training practices (RT); 2.75 for practices related to the promotion of interpersonal relationships (IR) About the private hospital, the results showed an average score of 3.24 for the CP; 2.83 for HR; 2.69 for IP; 2.71 for SW; 3.73 for EI; 2.56 for RT; 2.83 for IR at the hospital. Discussion: The analysis of organizational values of the studied hospitals shows that workers find the existence of hierarchical rigidity and the centralization of power in the institutions; believed there was cooperation at workplace, though they perceived individualism and competition; believed that values associated with the workers’ well-being, satisfaction and motivation were seldom acknowledged by the hospital; believed in the adoption of strategic planning actions within the institution, but considered interpersonal relationship promotion, continuous education and the rewarding of workers to be little valued by the institution. Conclusion: This work context can lead to professional dissatisfaction, compromising the quality of care and contributing to the occurrence of occupational diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nursing%20management" title="nursing management">nursing management</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20culture" title=" organizational culture"> organizational culture</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20care" title=" quality of care"> quality of care</a>, <a href="https://publications.waset.org/abstracts/search?q=interpersonal%20relationships" title=" interpersonal relationships"> interpersonal relationships</a> </p> <a href="https://publications.waset.org/abstracts/20757/organizational-culture-of-a-public-and-a-private-hospital-in-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20757.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">440</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">105</span> Existing Cardiovascular Risk among Children Diagnosed with Type 1 Diabetes Mellitus at the Emergency Clinic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masuma%20Novak">Masuma Novak</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Novak"> Daniel Novak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Sweden along with other Nordic countries has the highest incidence of type 1 diabetes mellitus (T1DM) worldwide. The trend is increasing globally. The diagnosis is often given at the emergency clinic when children arrive with cardinal symptom of T1DM. Children with T1DM are known to have an increased risk of microvascular- and macrovascular complications. A family history of cardiovascular complications may further increase their risk. Clinically evident diabetes-related vascular complications are however rarely visible in childhood and adolescence, whereby an intensive diabetes treatment and normoglycemic control is a goal for every child. This study is a risk evaluation of children with T1DM based on their family’s cardiovascular history. Method: Since 2005 the Better Diabetes Diagnosis (BDD) study is a nationwide Swedish prospective cohort study that recruits new-onset T1DM who are less than 18 years old at time of diagnosis. For each newly diagnosed child, blood samples are collected for specific HLA genotyping and islet autoantibody assays and their family’s cardiovascular history is evaluated. As part of the BDD study, during the years 2010-2013 all children diagnosed with T1DM at the Queen Silvia’s Children’s Hospital in Sweden were asked about their family’s cardiovascular history. Questions regarded maternal and paternal high blood pressure, stroke, and myocardial infarction before the age of 55 years, and hyperlipidemia were answered. A maximum risk score of eight was possible. All children are clinically observed prospectively for early functional and structural abnormalities such as protein uremia, blood pressure, and retinopathy. Results: A total of 275 children aged 0 to 18 years were diagnosed with T1DM at the Queen Silvia’s Children’s Hospital emergency clinic during this four year period. The participation rate was 99.7%. 26.4% of the children had no hereditary cardiovascular risk factors. 22.7 % had one risk factor and 18.8% had two risk factors. 14.8% had three risk factors. 9.7% had four risk factors and 7.5% had five risk factors or more. Conclusion: Among children with T1DM in Sweden there is a difference in hereditary cardiovascular risk factors. These results indicate that children with T1DM who also have increased hereditary cardiovascular risk factors should be monitored closely with early screening for functional and structural cardiovascular abnormalities. This is a very preliminary and ongoing study which will be complemented with the cardiovascular risk analysis among children without T1DM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=children" title="children">children</a>, <a href="https://publications.waset.org/abstracts/search?q=type%20I%20diabetes" title=" type I diabetes"> type I diabetes</a>, <a href="https://publications.waset.org/abstracts/search?q=emergency%20clinic" title=" emergency clinic"> emergency clinic</a>, <a href="https://publications.waset.org/abstracts/search?q=CVD%20risk" title=" CVD risk"> CVD risk</a> </p> <a href="https://publications.waset.org/abstracts/35301/existing-cardiovascular-risk-among-children-diagnosed-with-type-1-diabetes-mellitus-at-the-emergency-clinic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35301.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">365</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">104</span> VaR or TCE: Explaining the Preferences of Regulators</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Faroni">Silvia Faroni</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Le%20Courtois"> Olivier Le Courtois</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Ostaszewski"> Krzysztof Ostaszewski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> While a lot of research concentrates on the merits of VaR and TCE, which are the two most classic risk indicators used by financial institutions, little has been written on explaining why regulators favor the choice of VaR or TCE in their set of rules. In this paper, we investigate the preferences of regulators with the aim of understanding why, for instance, a VaR with a given confidence level is ultimately retained. Further, this paper provides equivalence rules that explain how a given choice of VaR can be equivalent to a given choice of TCE. Then, we introduce a new risk indicator that extends TCE by providing a more versatile weighting of the constituents of probability distribution tails. All of our results are illustrated using the generalized Pareto distribution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=generalized%20pareto%20distribution" title="generalized pareto distribution">generalized pareto distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=generalized%20tail%20conditional%20expectation" title=" generalized tail conditional expectation"> generalized tail conditional expectation</a>, <a href="https://publications.waset.org/abstracts/search?q=regulator%20preferences" title=" regulator preferences"> regulator preferences</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20measure" title=" risk measure"> risk measure</a> </p> <a href="https://publications.waset.org/abstracts/146694/var-or-tce-explaining-the-preferences-of-regulators" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146694.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">169</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">103</span> The 'Saudade' Market and the Development of Tourism in the Azores: An Analysis of Travel Preferences of Azorean Emigrants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Rocha">Silvia Rocha</a>, <a href="https://publications.waset.org/abstracts/search?q=Flavio%20Tiago"> Flavio Tiago</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Teresa%20Tiago"> Maria Teresa Tiago</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Faria"> Sandra Faria</a>, <a href="https://publications.waset.org/abstracts/search?q=Joao%20Couto"> Joao Couto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Azores have a tourist potential that has been developing, especially after an increase in promotion and the liberalization of airspace.

Looking to help fill this gap, a study of travelers from North America was conducted. Using cluster analysis, it was determined the existence of three segments: nostalgic, regular and frequent.

The here-presented approach aims at providing methodologies and tools to effectively manage these situations and fostering the implementation of virtuous symbiotic investments in manufacturing aggregations for a more sustainable production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=business%20model" title="business model">business model</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20symbiosis" title=" industrial symbiosis"> industrial symbiosis</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20agglomerations" title=" industrial agglomerations"> industrial agglomerations</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/62439/a-multi-level-approach-to-improve-sustainability-performances-of-industrial-agglomerations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62439.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">290</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">101</span> Pretreatment of Cattail (Typha domingensis) Fibers to Obtain Cellulose Nanocrystals </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marivane%20Turim%20Koschevic">Marivane Turim Koschevic</a>, <a href="https://publications.waset.org/abstracts/search?q=Maycon%20dos%20Santos"> Maycon dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcello%20Lima%20Bertuci"> Marcello Lima Bertuci</a>, <a href="https://publications.waset.org/abstracts/search?q=Farayde%20Matta%20Fakhouri"> Farayde Matta Fakhouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Maria%20Martelli"> Silvia Maria Martelli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Natural fibers are rich raw materials in cellulose and abundant in the world, its use for the cellulose nanocrystals extraction is promising as an example cited is the cattail, macrophyte native weed in South America.

Bacteria perceive chemical gradients in the environment, such as nutrients, and also other individual bacteria, and move toward or in the opposite direction to those signals. The application example considered as a case study consists in establishing the dependency between the reaction yield of hydrogels based on polyacrylamide and the working conditions such as time, temperature, monomer, initiator, crosslinking agent and inclusion polymer concentrations, as well as type of the polymer added. This process is modeled with a neural network which is included in an optimization procedure based on BFO. An experimental study of BFO parameters is performed. The results show that the algorithm is quite robust and can obtain good results for diverse combinations of parameter values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacterial%20foraging" title="bacterial foraging">bacterial foraging</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogels" title=" hydrogels"> hydrogels</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling%20and%20optimization" title=" modeling and optimization"> modeling and optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20networks" title=" neural networks"> neural networks</a> </p> <a href="https://publications.waset.org/abstracts/106154/a-bacterial-foraging-optimization-algorithm-applied-to-the-synthesis-of-polyacrylamide-hydrogels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106154.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">96</span> Smart Multifunctionalized and Responsive Polymersomes as Targeted and Selective Recognition Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Moreno">Silvia Moreno</a>, <a href="https://publications.waset.org/abstracts/search?q=Banu%20Iyisan"> Banu Iyisan</a>, <a href="https://publications.waset.org/abstracts/search?q=Hannes%20Gumz"> Hannes Gumz</a>, <a href="https://publications.waset.org/abstracts/search?q=Brigitte%20Voit"> Brigitte Voit</a>, <a href="https://publications.waset.org/abstracts/search?q=Dietmar%20Appelhans"> Dietmar Appelhans</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Polymersomes are materials which are considered as artificial counterparts of natural vesicles. The nanotechnology of such smart nanovesicles is very useful to enhance the efficiency of many therapeutic and diagnostic drugs. Those compounds show a higher stability, flexibility, and mechanical strength to the membrane compared to natural liposomes. In addition, they can be designed in detail, the permeability of the membrane can be controlled by different stimuli, and the surface can be functionalized with different biological molecules to facilitate monitoring and target. For this purpose, this study demonstrates the formation of multifunctional and pH sensitive polymersomes and their functionalization with different reactive groups or biomolecules inside and outside of polymersomes´ membrane providing by crossing the membrane and docking/undocking processes for biomedical applications. Overall, they are highly versatile and thus present new opportunities for the design of targeted and selective recognition systems, for example, in mimicking cell functions and in synthetic biology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multifunctionalized" title="multifunctionalized">multifunctionalized</a>, <a href="https://publications.waset.org/abstracts/search?q=pH%20stimulus" title=" pH stimulus"> pH stimulus</a>, <a href="https://publications.waset.org/abstracts/search?q=controllable%20release" title=" controllable release"> controllable release</a>, <a href="https://publications.waset.org/abstracts/search?q=cellular%20uptake" title=" cellular uptake"> cellular uptake</a> </p> <a href="https://publications.waset.org/abstracts/67024/smart-multifunctionalized-and-responsive-polymersomes-as-targeted-and-selective-recognition-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67024.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">320</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">95</span> Foreign Language Reading Comprehenmsion and the Linguistic Intervention Program</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Hvozd%C3%ADkov%C3%A1">Silvia Hvozdíková</a>, <a href="https://publications.waset.org/abstracts/search?q=Eva%20Stranovsk%C3%A1"> Eva Stranovská</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of the article is to discuss the results of the research conducted during the period of two semesters paying attention to selected factors of foreign language reading comprehension through the means of Linguistic Intervention Program.

Within the framework of the European DIGIECOQUARRY project, various services were developed for the identification of material quality, production estimation, detection of anomalies and prediction of consumption and production automatically with good results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aggregates" title="aggregates">aggregates</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=automatization" title=" automatization"> automatization</a>, <a href="https://publications.waset.org/abstracts/search?q=mining%20operations" title=" mining operations"> mining operations</a> </p> <a href="https://publications.waset.org/abstracts/175659/digitalization-in-aggregate-quarries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175659.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">88</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">92</span> Econophysics: The Use of Entropy Measures in Finance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Sheraz">Muhammad Sheraz</a>, <a href="https://publications.waset.org/abstracts/search?q=Vasile%20Preda"> Vasile Preda</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Dedu"> Silvia Dedu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Concepts of econophysics are usually used to solve problems related to uncertainty and nonlinear dynamics. In the theory of option pricing the risk neutral probabilities play very important role. The application of entropy in finance can be regarded as the extension of both information entropy and the probability entropy. It can be an important tool in various financial methods such as measure of risk, portfolio selection, option pricing and asset pricing. Gulko applied Entropy Pricing Theory (EPT) for pricing stock options and introduced an alternative framework of Black-Scholes model for pricing European stock option. In this article, we present solutions to maximum entropy problems based on Tsallis, Weighted-Tsallis, Kaniadakis, Weighted-Kaniadakies entropies, to obtain risk-neutral densities. We have also obtained the value of European call and put in this framework. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=option%20pricing" title="option pricing">option pricing</a>, <a href="https://publications.waset.org/abstracts/search?q=Black-Scholes%20model" title=" Black-Scholes model"> Black-Scholes model</a>, <a href="https://publications.waset.org/abstracts/search?q=Tsallis%20entropy" title=" Tsallis entropy"> Tsallis entropy</a>, <a href="https://publications.waset.org/abstracts/search?q=Kaniadakis%20entropy" title=" Kaniadakis entropy"> Kaniadakis entropy</a>, <a href="https://publications.waset.org/abstracts/search?q=weighted%20entropy" title=" weighted entropy"> weighted entropy</a>, <a href="https://publications.waset.org/abstracts/search?q=risk-neutral%20density" title=" risk-neutral density"> risk-neutral density</a> </p> <a href="https://publications.waset.org/abstracts/55546/econophysics-the-use-of-entropy-measures-in-finance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55546.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">303</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">91</span> Dynamic Thermal Modelling of a PEMFC-Type Fuel Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marco%20Avila%20Lopez">Marco Avila Lopez</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasnae%20Ait-Douchi"> Hasnae Ait-Douchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20De%20Los%20Santos"> Silvia De Los Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Badr%20Eddine%20Lebrouhi"> Badr Eddine Lebrouhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Pamela%20Ram%C3%ADrez%20Vidal"> Pamela Ramírez Vidal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the context of the energy transition, fuel cell technology has emerged as a solution for harnessing hydrogen energy and mitigating greenhouse gas emissions. An in-depth study was conducted on a PEMFC-type fuel cell, with an initiation of an analysis of its operational principles and constituent components. Subsequently, the modelling of the fuel cell was undertaken using the Python programming language, encompassing both steady-state and transient regimes. In the case of the steady-state regime, the physical and electrochemical phenomena occurring within the fuel cell were modelled, with the assumption of uniform temperature throughout all cell compartments. Parametric identification was carried out, resulting in a remarkable mean error of only 1.62% when the model results were compared to experimental data documented in the literature. The dynamic model that was developed enabled the scrutiny of the fuel cell's response in terms of temperature and voltage under varying current conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fuel%20cell" title="fuel cell">fuel cell</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic" title=" dynamic"> dynamic</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20model" title=" thermal model"> thermal model</a>, <a href="https://publications.waset.org/abstracts/search?q=PEMFC" title=" PEMFC"> PEMFC</a> </p> <a href="https://publications.waset.org/abstracts/176646/dynamic-thermal-modelling-of-a-pemfc-type-fuel-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176646.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">81</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">90</span> Designing and Evaluating Pedagogic Conversational Agents to Teach Children</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Tamayo-Moreno">Silvia Tamayo-Moreno</a>, <a href="https://publications.waset.org/abstracts/search?q=Diana%20P%C3%A9rez-Mar%C3%ADn"> Diana Pérez-Marín </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the possibility of children studying by using an interactive learning technology called Pedagogic Conversational Agent is presented. The main benefit is that the agent is able to adapt the dialogue to each student and to provide automatic feedback. Moreover, according to Math teachers, in many cases students are unable to solve the problems even knowing the procedure to solve them, because they do not understand what they have to do. The hypothesis is that if students are helped to understand what they have to solve, they will be able to do it. Taken that into account, we have started the development of Dr. Roland, an agent to help students understand Math problems following a User-Centered Design methodology. The use of this methodology is proposed, for the first time, to design pedagogic agents to teach any subject from Secondary down to Pre-Primary education. The reason behind proposing a methodology is that while working on this project, we noticed the lack of literature to design and evaluate agents. To cover this gap, we describe how User-Centered Design can be applied, and which usability techniques can be applied to evaluate the agent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pedagogic%20conversational%20agent" title="pedagogic conversational agent">pedagogic conversational agent</a>, <a href="https://publications.waset.org/abstracts/search?q=human-computer%20interaction" title=" human-computer interaction"> human-computer interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=user-centered%20design" title=" user-centered design"> user-centered design</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20language%20interface" title=" natural language interface"> natural language interface</a> </p> <a href="https://publications.waset.org/abstracts/67170/designing-and-evaluating-pedagogic-conversational-agents-to-teach-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67170.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">323</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">89</span> Colocalization Analysis to Understand Yttrium Uptake in Saxifraga paniculata Using Complementary Imaging Technics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Till%20Fehlauer">Till Fehlauer</a>, <a href="https://publications.waset.org/abstracts/search?q=Blanche%20Collin"> Blanche Collin</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernard%20Angeletti"> Bernard Angeletti</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Somogyi"> Andrea Somogyi</a>, <a href="https://publications.waset.org/abstracts/search?q=Claire%20Lallemand"> Claire Lallemand</a>, <a href="https://publications.waset.org/abstracts/search?q=Perrine%20Chaurand"> Perrine Chaurand</a>, <a href="https://publications.waset.org/abstracts/search?q=Ce%CC%81dric%20Dentant"> Cédric Dentant</a>, <a href="https://publications.waset.org/abstracts/search?q=Clement%20Levard"> Clement Levard</a>, <a href="https://publications.waset.org/abstracts/search?q=Jerome%20Rose"> Jerome Rose</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Over the last decades, yttrium (Y) has gained importance in high-tech applications. It is an essential part of alloys and compounds used for lasers, displays, or cell phones, for example. Due to its chemical similarities with the lanthanides, Y is often considered a rare earth element (REE). Despite their increased usage, the environmental behavior of REEs remains poorly understood. Especially regarding their interactions with plants, many uncertainties exist. On the one hand, Y is known to have a negative effect on root development and germination, but on the other hand, it appears to promote plant growth at low concentrations. In order to understand these phenomena, a precise knowledge is necessary about how Y is absorbed by the plant and how it is handled once inside the organism. Contradictory studies exist, stating that due to a similar ionic radius, Y and the other REEs might be absorbed through Ca²⁺-channels, while others suspect that Y has a shared pathway with Al³⁺. In this study, laser ablation coupled ICP-MS, and synchrotron-based micro-X-ray fluorescence (µXRF, beamline Nanoscopium, SOLEIL, France) have been used in order to localize Y within the plant tissue and identify associated elements. The plant used in this study is Saxifraga paniculata, a rugged alpine plant that has shown an affinity for Y in previous studies (in prep.). Furthermore, Saxifraga paniculata performs guttation, which means that it possesses phloem sap secreting openings on the leaf surface that serve to regulate root pressure. These so-called hydathodes could provide special insights in elemental transport in plants. The plants have been grown on Y doped soil (500mg/kg DW) for four months. The results showed that Y was mainly concentrated in the roots of Saxifraga paniculata (260 ± 85mg/kg), and only a small amount was translocated to the leaves (10 ± 7.8mg/kg). µXRF analysis indicated that within the root transects, the majority of Y remained in the epidermis and hardly penetrated the stele. Laser ablation coupled ICP-MS confirmed this finding and showed a positive correlation in the roots between Y, Fe, Al, and to a lesser extent Ca. In the stem transect, Y was mainly detected in a hotspot of approximately 40µm in diameter situated in the endodermis area. Within the stem and especially in the hotspot, Y was highly colocalized with Al and Fe. Similar-sized Y hotspots have been detected in/on the leaves. All of them were strongly colocalized with Al and Fe, except for those situated within the hydathodes, which showed no colocalization with any of the measured elements. Accordingly, a relation between Y and Ca during root uptake remains possible, whereas a correlation to Fe and Al appears to be dominant in the aerial parts, suggesting common storage compartments, the formation of complexes, or a shared pathway during translocation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laser%20ablation%20inductively%20coupled%20plasma%20mass%20spectrometry%20%28LA-ICP-MS%29" title="laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS)">laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS)</a>, <a href="https://publications.waset.org/abstracts/search?q=Phytoaccumulation" title=" Phytoaccumulation"> Phytoaccumulation</a>, <a href="https://publications.waset.org/abstracts/search?q=Rare%20earth%20elements" title=" Rare earth elements"> Rare earth elements</a>, <a href="https://publications.waset.org/abstracts/search?q=Saxifraga%20paniculata" title=" Saxifraga paniculata"> Saxifraga paniculata</a>, <a href="https://publications.waset.org/abstracts/search?q=Synchrotron-based%20micro-X-ray%20fluorescence" title=" Synchrotron-based micro-X-ray fluorescence"> Synchrotron-based micro-X-ray fluorescence</a>, <a href="https://publications.waset.org/abstracts/search?q=Yttrium" title=" Yttrium"> Yttrium</a> </p> <a href="https://publications.waset.org/abstracts/135671/colocalization-analysis-to-understand-yttrium-uptake-in-saxifraga-paniculata-using-complementary-imaging-technics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135671.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">148</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">88</span> HPLC-UV Screening of Legal (Caffeine and Yohimbine) and Illegal (Ephedrine and Sibutramine) Substances from Weight Loss Dietary Supplements for Athletes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amelia%20Tero-Vescan">Amelia Tero-Vescan</a>, <a href="https://publications.waset.org/abstracts/search?q=Camil-Eugen%20Vari"> Camil-Eugen Vari</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Ciulea"> Laura Ciulea</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Filip"> Cristina Filip</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Imre"> Silvia Imre</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A HPLC –UV method for the identification of ephedrine (EPH), sibutramine (SB), yohimbine (Y) and caffeine (CF) was developed.

The method allows quantitative determination of the four substances in a short analysis time and with minimum cost. The presence of SB and EPH in the analyzed DS was not detected while the content in CF and Y considering the dosage recommended by the manufacturer does not affect the health of the consumers.

Waist circumference is related to abdominal obesity which has a significant effect on the increase of blood pressure. Inulin is one of prebiotic, that has health benefits by offering the potential for lipid management, that can be useful to decrease the risk factor of metabolic syndrome. The aim of the research is to evaluate the effect of 10 gram inulin-substituted ice cream in waist circumference and blood pressure of abdominal obesity adolescents. Inulin had the ability to produce Short Chain Fatty Acid which can improve blood pressure and waist circumference. Systolic blood pressure was significantly decreased in the treatment group (p=0.028) with the mean of reduction 7.35 ± 11.59 mmHg. However, diastolic blood pressure and waist circumference showed no significant effect. Waist circumference, systolic blood pressure and diastolic blood pressure was decreased in control group. These results suggest that inulin-substituted ice cream used as therapeutics and prevention for the early onset of metabolic syndrome. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blood%20pressure" title="blood pressure">blood pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=inulin" title=" inulin"> inulin</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolic%20syndrome" title=" metabolic syndrome"> metabolic syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=waist%20circumference" title=" waist circumference"> waist circumference</a> </p> <a href="https://publications.waset.org/abstracts/66625/effect-of-inulin-substituted-ice-cream-on-waist-circumference-and-blood-pressure-of-adolescents-with-abdominal-obesity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66625.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">85</span> Critical Evaluation of Groundwater Monitoring Networks for Machine Learning Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Martinez-Santos">Pedro Martinez-Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=V%C3%ADctor%20G%C3%B3mez-Escalonilla"> Víctor Gómez-Escalonilla</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20D%C3%ADaz-Alcaide"> Silvia Díaz-Alcaide</a>, <a href="https://publications.waset.org/abstracts/search?q=Esperanza%20Montero"> Esperanza Montero</a>, <a href="https://publications.waset.org/abstracts/search?q=Miguel%20Mart%C3%ADn-Loeches"> Miguel Martín-Loeches</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Groundwater monitoring networks are critical in evaluating the vulnerability of groundwater resources to depletion and contamination, both in space and time. Groundwater monitoring networks typically grow over decades, often in organic fashion, with relatively little overall planning. The groundwater monitoring networks in the Madrid area, Spain, were reviewed for the purpose of identifying gaps and opportunities for improvement. Spatial analysis reveals the presence of various monitoring networks belonging to different institutions, with several hundred observation wells in an area of approximately 4000 km2. This represents several thousand individual data entries, some going back to the early 1970s. Major issues included overlap between the networks, unknown screen depth/vertical distribution for many observation boreholes, uneven time series, uneven monitored species, and potentially suboptimal locations. Results also reveal there is sufficient information to carry out a spatial and temporal analysis of groundwater vulnerability based on machine learning applications. These can contribute to improve the overall planning of monitoring networks’ expansion into the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=groundwater%20monitoring" title="groundwater monitoring">groundwater monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=observation%20networks" title=" observation networks"> observation networks</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=madrid" title=" madrid"> madrid</a> </p> <a href="https://publications.waset.org/abstracts/173455/critical-evaluation-of-groundwater-monitoring-networks-for-machine-learning-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173455.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">78</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">84</span> The Impact of Locations on the Perception of the Same Product: An Application to Motor Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Claudia%20Pellicelli">Anna Claudia Pellicelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Procacci"> Silvia Procacci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study aims to demonstrate how different locations, where the same product is unveiled and tested, can provide a different result in terms of perception by the same kind of people. The experiment was done in occasion of the presentation of a new bike. A group of dealers has been invited in Lloret de Mar, two persons from the headquarter were present to run the presentation, together with an outsourced trainer. Half day dedicated to the theoretical presentation and half day to the test of the new bike on the road, including the test of its direct competitors. The same presentation, organized in the same way, has been delivered in Italy, in 4 locations often used to run business meetings with dealers. In the end of all days of the presentation, dealers had to fill a questionnaire regarding the evaluation of the different bikes tested. The result of the questionnaire showed how the group invited in Spain rated much higher the new bike compared with the dealers testing the bike in locations already known and close to their home. So, in terms of business strategy, it is important to take into account how the location and the way of presenting any product or service can have a favourable impact on the people we want to convince. The next step of the experiment will be to cross check the sales of that bike with the dealers and measure if there is a relation between the top sellers and the one that appreciated the bike the most, in Spain. It would mean that they were able to transfer to customers the same good feelings and impressions they had in Spain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=product%20presentation" title="product presentation">product presentation</a>, <a href="https://publications.waset.org/abstracts/search?q=locations" title=" locations"> locations</a>, <a href="https://publications.waset.org/abstracts/search?q=emotional%20effect" title=" emotional effect"> emotional effect</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20strategy" title=" business strategy"> business strategy</a> </p> <a href="https://publications.waset.org/abstracts/76375/the-impact-of-locations-on-the-perception-of-the-same-product-an-application-to-motor-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76375.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">401</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">83</span> Effects of Whole Body Vibration on Movement Variability Performing a Resistance Exercise with Different Ballasts and Rhythms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S%C3%ADlvia%20tuy%C3%A0%20Vi%C3%B1as">Sílvia tuyà Viñas</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Fern%C3%A1ndez-Vald%C3%A9s"> Bruno Fernández-Valdés</a>, <a href="https://publications.waset.org/abstracts/search?q=Carla%20P%C3%A9rez-Chirinos"> Carla Pérez-Chirinos</a>, <a href="https://publications.waset.org/abstracts/search?q=Monica%20Morral-Yepes"> Monica Morral-Yepes</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucas%20del%20Campo%20Montoliu"> Lucas del Campo Montoliu</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerard%20Moras%20Feliu"> Gerard Moras Feliu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Some researchers stated that whole body vibration (WBV) generates postural destabilization, although there is no extensive research. Therefore, the aim of this study was to analyze movement variability when performing a half-squat with a different type of ballasts and rhythms with (V) and without (NV) WBV in male athletes using entropy. Twelve experienced in strength training males (age: 21.24  2.35 years, height: 176.83  5.80 cm, body mass: 70.63  8.58 kg) performed a half-squat with weighted vest (WV), dumbbells (D), and a bar with the weights suspended with elastic bands (B), in V and NV at 40 bpm and 60 bpm. Subjects performed one set of twelve repetitions of each situation, composed by the combination of the three factors. The movement variability was analyzed by calculating the Sample Entropy (SampEn) of the total acceleration signal recorded at the waist. In V, significant differences were found between D and WV (p<0.001; ES: 2.87 at 40 bpm; p<0.001; ES: 3.17 at 60 bpm) and between the B and WV at both rhythms (p<0.001; ES: 3.12 at 40 bpm; p<0.001; ES: 2.93 at 60 bpm) and a higher SampEn was obtained at 40 bpm with all ballasts (p<0.001; ES of WV: 1.22; ES of D: 4.49; ES of B: 4.03). No significant differences were found in NV. WBV is a disturbing and destabilizing stimulus. Strength and conditioning coaches should choose the combination of ballast and rhythm of execution according to the level and objectives of each athlete. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accelerometry" title="accelerometry">accelerometry</a>, <a href="https://publications.waset.org/abstracts/search?q=destabilization" title=" destabilization"> destabilization</a>, <a href="https://publications.waset.org/abstracts/search?q=entropy" title=" entropy"> entropy</a>, <a href="https://publications.waset.org/abstracts/search?q=movement%20variability" title=" movement variability"> movement variability</a>, <a href="https://publications.waset.org/abstracts/search?q=resistance%20training" title=" resistance training"> resistance training</a> </p> <a href="https://publications.waset.org/abstracts/141941/effects-of-whole-body-vibration-on-movement-variability-performing-a-resistance-exercise-with-different-ballasts-and-rhythms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141941.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">179</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">82</span> Logic Programming and Artificial Neural Networks in Pharmacological Screening of Schinus Essential Oils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Neves">José Neves</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Ros%C3%A1rio%20Martins"> M.

In the first phase of this research, a segment of road was designed using recycled materials such as Reclaimed Asphalt Pavement (RAP) on the top, the natural coarse base including 30% of RAP and recycled concrete blocks. The second part of this segment was designed using regular materials for each layer of the pavement. Both structures were built next to each other in order to analyze and measure the material properties as well as performance and environmental factors in the pavement under real traffic and weather conditions. Different monitoring devices were installed among the structure, based on the literature revision, such as soil cells, linear potentiometer, moisture sensors, and strain gauges that help us to know the C&DW as a part of the pavement structure. This research includes not only the physical characterization but also the measured parameters in a field such as an asphalt mixture (RAP) strain (ετ), vertical strain (εᵥ) and moisture control in coarse layers (%w), and the applied loads and strain in the subgrade (εᵥ). The results will show us what is happening with these materials in order to obtain not only a sustainable solution but also to know its behavior and lifecycle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainable%20pavements" title="sustainable pavements">sustainable pavements</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20%26%20demolition%20waste-C%26DW" title=" construction & demolition waste-C&DW"> construction & demolition waste-C&DW</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20rigid%20concrete" title=" recycled rigid concrete"> recycled rigid concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=reclaimed%20asphalt%20pavement-rap" title=" reclaimed asphalt pavement-rap"> reclaimed asphalt pavement-rap</a> </p> <a href="https://publications.waset.org/abstracts/131436/instrumentation-of-urban-pavements-built-with-construction-and-demolition-waste" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131436.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">161</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">80</span> Stress and Coping Strategies: A Correlational Analysis to Profiling Maladaptive Behaviors at Work</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Riva">Silvia Riva</a>, <a href="https://publications.waset.org/abstracts/search?q=Ezekiel%20Chinyio"> Ezekiel Chinyio</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Workers in different sectors are prone to stress at varying levels. They also respond to stress in different ways. An inspiration was to study stress development amongst workers in a work dangerous setting (Construction Industry) as well as how they cope with specific stress incidences. Objective: The overarching objective of the study was to study and correlate between stress and coping strategies. The research was conducted in an organizational industrial setting, and its findings on the coping actions of construction workers are reported in this article. Methods: An online cross-sectional survey was conducted with 80 participants aged 18-62. These were working for three different construction organizations in the West Midland region of the UK. Their coping actions were assessed using the COPE Inventory (Carver, 2013) instrument while the level of stress was assessed by the Perceived Stress Scale (Cohen, 1994). Results: Out of 80 workers (20 female, 25%, mean age 40.66), positive reinterpretation (M=4.15, SD=2.60) and active coping (M=4.18, SD=2.55) were the two most adaptive strategies reported by the workers while the most frequent maladaptive behavior was mental disengagement (M=3.62, SD=2.25). Among the maladaptive tactics, alcohol and drug abuse was a significant moderator in stress reactions (t=6.12, p=.000). Conclusion: Some maladaptive strategies are adopted by construction workers to cope with stress. So, it could be argued that programs of stress prevention and control in the construction industry have a basis to develop solutions that can improve and strengthen effective interventions when workers are stressed or getting stressed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coping" title="coping">coping</a>, <a href="https://publications.waset.org/abstracts/search?q=organization" title=" organization"> organization</a>, <a href="https://publications.waset.org/abstracts/search?q=strategies" title=" strategies"> strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a> </p> <a href="https://publications.waset.org/abstracts/102736/stress-and-coping-strategies-a-correlational-analysis-to-profiling-maladaptive-behaviors-at-work" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102736.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">79</span> Mineral Nitrogen Retention, Nitrogen Availability and Plant Growth in the Soil Influenced by Addition of Organic and Mineral Fertilizers: Lysimetric Experiment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luk%C3%A1%C5%A1%20Plo%C5%A1ek">Lukáš Plošek</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaroslav%20Hyn%C5%A1t"> Jaroslav Hynšt</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaroslav%20Z%C3%A1hora"> Jaroslav Záhora</a>, <a href="https://publications.waset.org/abstracts/search?q=Jakub%20Elbl"> Jakub Elbl</a>, <a href="https://publications.waset.org/abstracts/search?q=Anton%C3%ADn%20Kintl"> Antonín Kintl</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivana%20Charousov%C3%A1"> Ivana Charousová</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Kov%C3%A1csov%C3%A1"> Silvia Kovácsová</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Compost can influence soil fertility and plant health. At the same time compost can play an important role in the nitrogen cycle and it can influence leaching of mineral nitrogen from soil to underground water. This paper deals with the influence of compost addition and mineral nitrogen fertilizer on leaching of mineral nitrogen, nitrogen availability in microbial biomass and plant biomass production in the lysimetric experiment. Twenty-one lysimeters were filed with topsoil and subsoil collected in the area of protection zone of underground source of drinking water - Březová nad Svitavou. The highest leaching of mineral nitrogen was detected in the variant fertilized only mineral nitrogen fertilizer (624.58 mg m-2), the lowest leaching was recorded in the variant with high addition of compost (315.51 mg m-2). On the other hand, losses of mineral nitrogen are not in connection with the losses of available form of nitrogen in microbial biomass. Because loss of mineral nitrogen was detected in variant with the least change in the availability of N in microbial biomass. The leaching of mineral nitrogen, yields as well as the results concerning nitrogen availability from the first year of long term experiment suggest that compost can positive influence the leaching of nitrogen into underground water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nitrogen" title="nitrogen">nitrogen</a>, <a
