Advances in technology have been delivering machines capable of autonomous expression, both through communication and art. This paper deals with models (theoretical approach) and experiments (applied approach) related to artificial agents. On one hand it traces how social sciences' scholars have worked with topics such as text automatization, man-machine writing cooperation, and communication. On the other hand it covers how computer sciences' scholars have built communicative and artistic machines, including the programming of creativity. The aim is to present a brief survey on artificially intelligent communicators and artificially creative writers, and provide the basis to understand the meta-authorship and also to new and further man-machine co-authorship. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20communication" title="artificial communication">artificial communication</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20creativity" title=" artificial creativity"> artificial creativity</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20writers" title=" artificial writers"> artificial writers</a>, <a href="https://publications.waset.org/abstracts/search?q=meta-authorship" title=" meta-authorship"> meta-authorship</a>, <a href="https://publications.waset.org/abstracts/search?q=robotic%20art" title=" robotic art"> robotic art</a> </p> <a href="https://publications.waset.org/abstracts/51732/communicative-and-artistic-machines-a-survey-of-models-and-experiments-on-artificial-agents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51732.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">293</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Comparison between Approaches Used in Two Walk About Projects </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Derek%20O%20Reilly">Derek O Reilly</a>, <a href="https://publications.waset.org/abstracts/search?q=Piotr%20Milczarski"> Piotr Milczarski</a>, <a href="https://publications.waset.org/abstracts/search?q=Shane%20Dowdall"> Shane Dowdall</a>, <a href="https://publications.waset.org/abstracts/search?q=Artur%20H%C5%82oba%C5%BC"> Artur Hłobaż</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Podlaski"> Krzysztof Podlaski</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiram%20Bollaert"> Hiram Bollaert </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Learning through creation of contextual games is a very promising way/tool for interdisciplinary and international group projects.

The system of prefabrication invented by Ford had inspired them to try to create a system or prototype that could become the basis for the mass 'production' of houses. The attempts made by Le Corbusier, Buckminster Fuller or Charles and Ray Eames, among others, are well known in this regard. The economic attractiveness of replicable, mass-producible houses meant that experiments in this area were undertaken in both the West and the East. Among such attempts was the project of dome-shaped houses conceived by the architect and inventor Andrzej Iwanicki and realised between 1961 and 1966 in Warsaw's Okęcie district on Ustrzycka Street. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dome%20houses" title="dome houses">dome houses</a>, <a href="https://publications.waset.org/abstracts/search?q=polish%20modernism" title=" polish modernism"> polish modernism</a>, <a href="https://publications.waset.org/abstracts/search?q=postwar%20modernism" title=" postwar modernism"> postwar modernism</a>, <a href="https://publications.waset.org/abstracts/search?q=modernist%20houses" title=" modernist houses"> modernist houses</a> </p> <a href="https://publications.waset.org/abstracts/167147/between-an-idea-and-the-experiment-dome-houses-in-warsaw" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167147.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">108</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Why Use of Artificial Intelligence Should Be Centred around Emotions to Create Effective Learning Environment in the Corporate Workplace?</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Artur%20Willo%C5%84ski">Artur Willoński</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research introduces the concept of Emotions Based Collaborative Prompting (EBCP) as a response to the need for a unified learning environment in the corporate workplace. The first section examines the key characteristics of workplace learning, presenting three core propositions: (1) workplace learning is both informal and diverse, requiring adaptable approaches; (2) corporate settings provide inherent structures that can be leveraged for collaborative learning; and (3) emotional engagement and human interaction play a central role in effective learning processes. The second section describes how EBCP framework creates an environment that helps identify emotions, assign emotions with parameters, and allows these parameters to be collected, analysed, and turned into a context-aware learning environment. It concludes that EBCP allows people who come from different social backgrounds, age groups, and positions in the organisation to collaborate and generate knowledge based on both formal and informal interactions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collaborative%20learning" title="collaborative learning">collaborative learning</a>, <a href="https://publications.waset.org/abstracts/search?q=self-regulated%20learning" title=" self-regulated learning"> self-regulated learning</a>, <a href="https://publications.waset.org/abstracts/search?q=emotions" title=" emotions"> emotions</a>, <a href="https://publications.waset.org/abstracts/search?q=AI" title=" AI"> AI</a> </p> <a href="https://publications.waset.org/abstracts/195455/why-use-of-artificial-intelligence-should-be-centred-around-emotions-to-create-effective-learning-environment-in-the-corporate-workplace" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/195455.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">4</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> Ecotoxicological Safety of Wastewater Treated with Lignocellulosic Adsorbents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lu%C3%ADsa%20P.%20Cruz-Lopes">Luísa P.

In this work grape stalks and olive cake were used as lignocellulosic adsorbents for wastewater containing lead treatment. To attain a better knowledge of the factors that could influence the quality of the treated wastewater, a chemical characterization of the materials used in the treatment was done. To access the ecotoxicological safety of the treated wastewater, several tests were performed. The results of the toxicity test show that the samples leachate has a mild effect on the living models tested. The tests performed in lemna and bacteria were the most sensible to toxicity effects of the samples. The results obtained in this work evidenced the importance of use of simple and fast toxicity tests to predict impacts in the environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20composition" title="chemical composition">chemical composition</a>, <a href="https://publications.waset.org/abstracts/search?q=lignocellulosic%20residues" title=" lignocellulosic residues"> lignocellulosic residues</a>, <a href="https://publications.waset.org/abstracts/search?q=ecotoxicological%20safety" title=" ecotoxicological safety"> ecotoxicological safety</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater" title=" wastewater"> wastewater</a> </p> <a href="https://publications.waset.org/abstracts/7640/ecotoxicological-safety-of-wastewater-treated-with-lignocellulosic-adsorbents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7640.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">282</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> Application of UAS in Forest Firefighting for Detecting Ignitions and 3D Fuel Volume Estimation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Artur%20Krukowski">Artur Krukowski</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanouela%20Vogiatzaki"> Emmanouela Vogiatzaki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The article presents results from the AF3 project “Advanced Forest Fire Fighting” focused on Unmanned Aircraft Systems (UAS)-based 3D surveillance and 3D area mapping using high-resolution photogrammetric methods from multispectral imaging, also taking advantage of the 3D scanning techniques from the SCAN4RECO project.

The article charts the course of subversion analysis when applied to a fuel injection nozzle of a marine engine. The work describes the fuel injector nozzle as a technological system and presents principles of analysis for the causes of a cracked tip of the nozzle body. The system is modelled with functional analysis. A search for potential causes of the damage is undertaken and a cause-and-effect analysis for various hypotheses concerning the damage is drawn up. The importance of particular hypotheses is evaluated and the most likely causes of damage identified. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=complex%20technical%20system" title="complex technical system">complex technical system</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20injector" title=" fuel injector"> fuel injector</a>, <a href="https://publications.waset.org/abstracts/search?q=function%20analysis" title=" function analysis"> function analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=importance%20analysis" title=" importance analysis"> importance analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=resource%20analysis" title=" resource analysis"> resource analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=sabotage%20analysis" title=" sabotage analysis"> sabotage analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=subversion%20analysis" title=" subversion analysis"> subversion analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=TRIZ%20%28Theory%20of%20Inventive%20Problem%20Solving%29" title=" TRIZ (Theory of Inventive Problem Solving)"> TRIZ (Theory of Inventive Problem Solving)</a> </p> <a href="https://publications.waset.org/abstracts/79670/application-of-subversion-analysis-in-the-search-for-the-causes-of-cracking-in-a-marine-engine-injector-nozzle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79670.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">618</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> Protection of Cultural Heritage against the Effects of Climate Change Using Autonomous Aerial Systems Combined with Automated Decision Support</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Artur%20Krukowski">Artur Krukowski</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanouela%20Vogiatzaki"> Emmanouela Vogiatzaki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The article presents an ongoing work in research projects such as SCAN4RECO or ARCH, both funded by the European Commission under Horizon 2020 program. The former one concerns multimodal and multispectral scanning of Cultural Heritage assets for their digitization and conservation via spatiotemporal reconstruction and 3D printing, while the latter one aims to better preserve areas of cultural heritage from hazards and risks. It co-creates tools that would help pilot cities to save cultural heritage from the effects of climate change.

Since the popularization of social networking sites (SNSs) such as Facebook and Twitter, these magazines are trying to adapt their content to these new media. In this study, one hundred posts of popular science magazines on Facebook are analyzed regarding the use of genres of communication and readers’ reactions. The quantitative analysis of these features considers the variety of genres and how the users of Facebook answer to them (liking, sharing and commenting). The first hypothesis was that these magazines used the genres of communication posted on Facebook both to marketing and informational purposes and that these mixed intentions have an impact in the number of readers’ reactions. In order to analyze these features, twenty timeline posts published by five magazines: Cosmos, Galileu, New Scientist, Scientific American and Superinteressante were gathered during the period of three days (6th November 2015–8th November 2015). This research shows that the hyperlinks posted by these magazines created ways to diversify the communication genres used on their pages and, at the same time, revealed that, overall, readers react quantitatively different to these genres. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Facebook" title="Facebook">Facebook</a>, <a href="https://publications.waset.org/abstracts/search?q=genres%20of%20communication" title=" genres of communication"> genres of communication</a>, <a href="https://publications.waset.org/abstracts/search?q=likes" title=" likes"> likes</a>, <a href="https://publications.waset.org/abstracts/search?q=popular%20science%20magazines" title=" popular science magazines"> popular science magazines</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20networking%20sites" title=" social networking sites"> social networking sites</a> </p> <a href="https://publications.waset.org/abstracts/69309/genres-of-communication-and-readers-reactions-popular-science-magazines-on-facebook" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69309.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">402</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> Ambidentate Ligands as Platforms for Efficient Synthesis of Pd-based Metallosupramolecular Cages</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wojcieh%20Dro%C5%BCd%C5%BC">Wojcieh Drożdż</a>, <a href="https://publications.waset.org/abstracts/search?q=Artur%20R.%20Stefankiewicz"> Artur R.

These features enable the coordination of two different metal ions, which can directly affect the properties of obtained complexes as well as further application. In the current research, we focused on a β-diketone ligand containing terminally located pyridine units in order to assemble cage-like architectures. This will be possible due to the peculiar geometry of the proposed ligands, called "banana-shape", widely used in the synthesis of sophisticated metallosupramolecular architectures. Each of the coordination units plays an important role in cage assembly. Pyridine units enable the coordination of square-planar metal ions (Pd²⁺, Pt²⁺), forming a positively charged cage. On the other hand, the β-diketone group provides the possibility of post-modification, including the introduction of additional functional groups with specific properties (sensing, catalytic, etc.). Such obtained cages are of great interest due to their application potential, including storage or transport of guest molecules, selective detection/separation of analytes as well as efficient catalytic processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metalloligands" title="metalloligands">metalloligands</a>, <a href="https://publications.waset.org/abstracts/search?q=coordination%20cages" title=" coordination cages"> coordination cages</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoreactors" title=" nanoreactors"> nanoreactors</a>, <a href="https://publications.waset.org/abstracts/search?q=%CE%B2-diketonate%20complexes" title=" β-diketonate complexes"> β-diketonate complexes</a> </p> <a href="https://publications.waset.org/abstracts/167196/ambidentate-ligands-as-platforms-for-efficient-synthesis-of-pd-based-metallosupramolecular-cages" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167196.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">73</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> Multimedia Firearms Training System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aleksander%20Nawrat">Aleksander Nawrat</a>, <a href="https://publications.waset.org/abstracts/search?q=Karol%20J%C4%99drasiak"> Karol Jędrasiak</a>, <a href="https://publications.waset.org/abstracts/search?q=Artur%20Ryt"> Artur Ryt</a>, <a href="https://publications.waset.org/abstracts/search?q=Dawid%20Sobel"> Dawid Sobel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The goal of the article is to present a novel Multimedia Firearms Training System. The system was developed in order to compensate for major problems of existing shooting training systems. The designed and implemented solution can be characterized by five major advantages: algorithm for automatic geometric calibration, algorithm of photometric recalibration, firearms hit point detection using thermal imaging camera, IR laser spot tracking algorithm for after action review analysis, and implementation of ballistics equations. The combination of the abovementioned advantages in a single multimedia firearms training system creates a comprehensive solution for detecting and tracking of the target point usable for shooting training systems and improving intervention tactics of uniformed services. The introduced algorithms of geometric and photometric recalibration allow the use of economically viable commercially available projectors for systems that require long and intensive use without most of the negative impacts on color mapping of existing multi-projector multimedia shooting range systems.

Although she is less known to the general public than her more famous cousins, this species has many therapeutic properties that have been used for centuries in traditional medicine of some regions. For generations, Satureja hispidula has been used in traditional medicine to treat various ailments, including respiratory diseases and diabetes. Its aroma, often described as close to that of mint, gives it a special interest in aromatherapy. Due to the growing interest in the beneficial properties of plant-derived essential oils, the aim of this study is to analyze the chemical composition of S. hispidula essential oil by gas chromatography coupled with mass spectrometry (GC-MS). Identifying the main constituents of essential oil will allow better understanding its chemical nature and exploring its potential for culinary and therapeutic application. The study of the essential oil of S. hispidula reveals a composition rich in 83 compounds, including menthone, pulegone and piperitone as main constituents. This gas chromatography analysis coupled with mass spectrometry provides valuable information about the chemical nature of this oil. However, more in-depth studies are needed to explore the potentially health-enhancing properties of this essential oil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=satureja%20hispidula" title="satureja hispidula">satureja hispidula</a>, <a href="https://publications.waset.org/abstracts/search?q=GC-MS" title=" GC-MS"> GC-MS</a>, <a href="https://publications.waset.org/abstracts/search?q=essential%20oil" title=" essential oil"> essential oil</a>, <a href="https://publications.waset.org/abstracts/search?q=menthone" title=" menthone"> menthone</a>, <a href="https://publications.waset.org/abstracts/search?q=pulegone" title=" pulegone"> pulegone</a> </p> <a href="https://publications.waset.org/abstracts/188874/gc-ms-analysis-of-essential-oil-from-satureja-hispidula-a-medicinal-plant-from-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188874.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">28</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Choosing Local Organic Food: Consumer Motivations and Ethical Spaces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Artur%20Saraiva">Artur Saraiva</a>, <a href="https://publications.waset.org/abstracts/search?q=Moritz%20von%20Schwedler"> Moritz von Schwedler</a>, <a href="https://publications.waset.org/abstracts/search?q=Em%C3%ADlia%20Fernandes"> Emília Fernandes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, the organic sector has increased significantly. However, with the ‘conventionalization’ of these products, it has been questioned whether these products have been losing their original vision. Accordingly, this research based on 31 phenomenological interviews with committed organic consumers in urban and rural areas of Portugal, aims to analyse how ethical motivations and ecological awareness are related to organic food consumption. The content thematic analysis highlights aspects related to society and environmental concerns. On an individual level, the importance of internal coherence, peace of mind and balance that these consumers find in the consumption of local organic products was stressed. For these consumers, local organic products consumption made for significant changes in their lives, aiding in the establishment of a green identity, and involves a certain philosophy of life. This vision of an organic lifestyle is grounded in a political and ecological perspective, beyond the usual organic definition, as a ‘post-organic era’. The paper contributes to better understand how an ideological environmental discourse allows highlighting the relationship between consumers’ environmental concerns and the politics of food, resulting in a possible transition to new sustainable consumption practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=organic%20consumption" title="organic consumption">organic consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=localism" title=" localism"> localism</a>, <a href="https://publications.waset.org/abstracts/search?q=content%20thematic%20analysis" title=" content thematic analysis"> content thematic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=pro-environmental%20discourse" title=" pro-environmental discourse"> pro-environmental discourse</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20consumption" title=" political consumption"> political consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=Portugal" title=" Portugal"> Portugal</a> </p> <a href="https://publications.waset.org/abstracts/77263/choosing-local-organic-food-consumer-motivations-and-ethical-spaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77263.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">214</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Adaptation to Repeated Eccentric Exercise Assessed by Double to Single Twitch Ratio</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Damian%20Janecki">Damian Janecki</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Jask%C3%B3lska"> Anna Jaskólska</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaros%C5%82aw%20Marusiak"> Jarosław Marusiak</a>, <a href="https://publications.waset.org/abstracts/search?q=Artur%20Jask%C3%B3lski"> Artur Jaskólski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to assess double to single twitch ratio after two bouts of eccentric exercise of the elbow flexors.

Maximal isometric torque and electrically evoked responses decreased significantly in all measurements after the first bout of eccentric exercise (P<0.05). In measurements performed at 24 and 48 hours after the second bout both maximal voluntary isometric torque and electrically evoked contractions were significantly higher than in measurements performed after the fist bout (P<0.05). Although low-frequency fatigue significantly increased up to 48 hours after each bout of eccentric exercise, its values at 24 and 48 hours after the second bout were significantly lower than at respective time points after the first bout (P<0.05). Smaller changes in double to single twitch ratio at 24 and 48 hours after the second bout of eccentric exercise reflects repeated bout effect that confers protection against subsequent exercise-induced muscle damage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biceps%20brachii" title="biceps brachii">biceps brachii</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20stimulation" title=" electrical stimulation"> electrical stimulation</a>, <a href="https://publications.waset.org/abstracts/search?q=lenghtening%20contractions" title=" lenghtening contractions"> lenghtening contractions</a>, <a href="https://publications.waset.org/abstracts/search?q=repeated%20bout%20effect" title=" repeated bout effect "> repeated bout effect </a> </p> <a href="https://publications.waset.org/abstracts/49190/adaptation-to-repeated-eccentric-exercise-assessed-by-double-to-single-twitch-ratio" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49190.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">14</span> Analysis of the Effect of Increased Self-Awareness on the Amount of Food Thrown Away</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agnieszka%20Dubiel">Agnieszka Dubiel</a>, <a href="https://publications.waset.org/abstracts/search?q=Artur%20Grabowski"> Artur Grabowski</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomasz%20Przerywacz"> Tomasz Przerywacz</a>, <a href="https://publications.waset.org/abstracts/search?q=Mateusz%20Roganowicz"> Mateusz Roganowicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrycja%20Zioty"> Patrycja Zioty</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Food waste is one of the most significant challenges humanity is facing nowadays. Every year, reports from global organizations show the scale of the phenomenon, although society's awareness is still insufficient. One-third of the food produced in the world is wasted at various points in the food supply chain. Wastes are present from the delivery through the food preparation and distribution to the end of the sale and consumption. The first step in understanding and resisting the phenomenon is a thorough analysis of the everyday behaviors of humanity. This concept is understood as finding the correlation between the type of food and the reason for throwing it out and wasting it. Those actions were identified as a critical step in the start of work to develop technology to prevent food waste. In this paper, the problem mentioned above was analyzed by focusing on the inhabitants of Central Europe, especially Poland, aged 20-30. This paper provides an insight into collecting data through dedicated software and an organized database. The proposed database contains information on the amount, type, and reasons for wasting food in households. A literature review supported the work to answer research questions, compare the situation in Poland with the problem analyzed in other countries, and find research gaps. The proposed article examines the cause of food waste and its quantity in detail. This review complements previous reviews by emphasizing social and economic innovation in Poland's food waste management. The paper recommends a course of action for future research on food waste management and prevention related to the handling and disposal of food, emphasizing households, i.e., the last link in the supply chain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20waste" title="food waste">food waste</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20waste%20reduction" title=" food waste reduction"> food waste reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=consumer%20food%20waste" title=" consumer food waste"> consumer food waste</a>, <a href="https://publications.waset.org/abstracts/search?q=human-food%20interaction" title=" human-food interaction"> human-food interaction</a> </p> <a href="https://publications.waset.org/abstracts/151378/analysis-of-the-effect-of-increased-self-awareness-on-the-amount-of-food-thrown-away" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151378.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">119</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Liquid-Liquid Plug Flow Characteristics in Microchannel with T-Junction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Yagodnitsyna">Anna Yagodnitsyna</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Kovalev"> Alexander Kovalev</a>, <a href="https://publications.waset.org/abstracts/search?q=Artur%20Bilsky"> Artur Bilsky</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The efficiency of certain technological processes in two-phase microfluidics such as emulsion production, nanomaterial synthesis, nitration, extraction processes etc. depends on two-phase flow regimes in microchannels. For practical application in chemistry and biochemistry it is very important to predict the expected flow pattern for a large variety of fluids and channel geometries. In the case of immiscible liquids, the plug flow is a typical and optimal regime for chemical reactions and needs to be predicted by empirical data or correlations. In this work flow patterns of immiscible liquid-liquid flow in a rectangular microchannel with T-junction are investigated. Three liquid-liquid flow systems are considered, viz. kerosene – water, paraffin oil – water and castor oil – paraffin oil. Different flow patterns such as parallel flow, slug flow, plug flow, dispersed (droplet) flow, and rivulet flow are observed for different velocity ratios. New flow pattern of the parallel flow with steady wavy interface (serpentine flow) has been found. It is shown that flow pattern maps based on Weber numbers for different liquid-liquid systems do not match well. Weber number multiplied by Ohnesorge number is proposed as a parameter to generalize flow maps. Flow maps based on this parameter are superposed well for all liquid-liquid systems of this work and other experiments. Plug length and velocity are measured for the plug flow regime. When dispersed liquid wets channel walls plug length cannot be predicted by known empirical correlations. By means of particle tracking velocimetry technique instantaneous velocity fields in a plug flow regime were measured. Flow circulation inside plug was calculated using velocity data that can be useful for mass flux prediction in chemical reactions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flow%20patterns" title="flow patterns">flow patterns</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrodynamics" title=" hydrodynamics"> hydrodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid-liquid%20flow" title=" liquid-liquid flow"> liquid-liquid flow</a>, <a href="https://publications.waset.org/abstracts/search?q=microchannel" title=" microchannel"> microchannel</a> </p> <a href="https://publications.waset.org/abstracts/67484/liquid-liquid-plug-flow-characteristics-in-microchannel-with-t-junction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67484.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">395</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> COVID-19 and Heart Failure Outcomes: Readmission Insights from the 2020 United States National Readmission Database</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Induja%20R.%20Nimma">Induja R.

We felt it pertinent to analyze 30-day readmission causes and outcomes among patients with HCF-19 using the United States using real-world big data via the National readmission database. Objective: The aim is to describe the rate and causes of readmissions and morbidity of heart failure with coinciding COVID-19 (HFC-19) in the United States, using the 2020 National Readmission Database (NRD). Methods: A descriptive, retrospective study was conducted on the 2020 NRD, a nationally representative sample of all US hospitalizations. Adult (>18 years) inpatient admissions with COVID-19 with HF and readmissions in 30 days were selected based on the International Classification of Diseases-Tenth Revision, Procedure Code. Results: In 2020, 2,60,372 adult patients were hospitalized with COVID-19 and HF. The median age was 74 (IQR: 64-83), and 47% were female. The median length of stay was 7(4-13) days, and the total cost of stay was 62,025 (31,956 – 130,670) United States dollars, respectively. Among the index hospital admissions, 61,527 (23.6%) died, and 22,794 (11.5%) were readmitted within 30 days. The median age of patients readmitted in 30 days was 73 (63-82), 45% were female, and 1,962 (16%) died. The most common principal diagnosis for readmission in these patients was COVID-19= 34.8%, Sepsis= 16.5%, HF = 7.1%, AKI = 2.2%, respiratory failure with hypoxia =1.7%, and Pneumonia = 1%. Conclusion: The rate of readmission in patients with heart failure exacerbations is increasing yearly. COVID-19 was observed to be the most common principal diagnosis in patients readmitted within 30 days. Complicated hypertension, chronic pulmonary disease, complicated diabetes, renal failure, alcohol use, drug use, and peripheral vascular disorders are risk factors associated with readmission. Familiarity with the most common causes and predictors for readmission helps guide the development of initiatives to minimize adverse outcomes and the cost of medical care. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Covid-19" title="Covid-19">Covid-19</a>, <a href="https://publications.waset.org/abstracts/search?q=heart%20failure" title=" heart failure"> heart failure</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20readmission%20database" title=" national readmission database"> national readmission database</a>, <a href="https://publications.waset.org/abstracts/search?q=readmission%20outcomes" title=" readmission outcomes"> readmission outcomes</a> </p> <a href="https://publications.waset.org/abstracts/162273/covid-19-and-heart-failure-outcomes-readmission-insights-from-the-2020-united-states-national-readmission-database" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162273.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">79</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Multicellular Cancer Spheroids as an in Vitro Model for Localized Hyperthermia Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kamila%20Dus-Szachniewicz">Kamila Dus-Szachniewicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Artur%20Bednarkiewicz"> Artur Bednarkiewicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Katarzyna%20Gdesz-Birula"> Katarzyna Gdesz-Birula</a>, <a href="https://publications.waset.org/abstracts/search?q=Slawomir%20Drobczynski"> Slawomir Drobczynski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In modern oncology hyperthermia (HT) is defined as a controlled tumor heating. HT treatment temperatures range between 40–48 °C and can selectively damage heat-sensitive cancer cells or limit their further growth, usually with minimal injury to healthy tissues. Despite many advantages, conventional whole-body and regional hyperthermia have clinically relevant side effects, including cardiac and vascular disorders. Additionally, the lack of accessibility of deep-seated tumor sites and impaired targeting micrometastases renders HT less effective. It is believed that above disadvantages can significantly overcome by the application of biofunctionalized microparticles, which can specifically target tumor sites and become activated by an external stimulus to provide a sufficient cellular response. In our research, the unique optical tweezers system have enabled capturing the silica microparticles, primary cells and tumor spheroids in highly controllable and reproducible environment to study the impact of localized heat stimulation on normal and pathological cell and within multicellular tumor spheroid. High throughput spheroid model was introduced to better mimic the response to HT treatment on tumors in vivo. Additionally, application of local heating of tumor spheroids was performed in strictly controlled conditions resembling tumor microenvironment (temperature, pH, hypoxia, etc.), in response to localized and nonhomogeneous hyperthermia in the extracellular matrix, which promotes tumor progression and metastatic spread. The lack of precise control over these well- defined parameters in basic research leads to discrepancies in the response of tumor cells to the new treatment strategy in preclinical animal testing. The developed approach enables also sorting out subclasses of cells, which exhibit partial or total resistance to therapy, in order to understand fundamental aspects of the resistance shown by given tumor cells in response to given therapy mode and conditions.

In this area, the most known and widespread are recycling processes, which are mainly focused on the reuse of material. Another possible solution used in various companies to achieve improvement in sustainable development is waste-free production. It involves the production exclusively from such materials, whose waste is included in the group of renewable raw materials. This means that they can: (i) be recycled directly during the manufacturing process of further products or (ii) be raw material obtained by other companies for the production of alternative products. The article presents the possibility of using post-production clay from the Jurassic limestone deposit "Raciszyn II" as a raw material for the production of alkali activated materials (AAM). Such products are currently increasingly used, mostly in various building applications. However, their final properties depend significantly on many factors; the most important of them are: chemical composition of the raw material, particle size, specific surface area, type and concentration of the activator and the temperature range of the heat treatment. Conducted mineralogical and chemical analyzes of clay from the “Raciszyn II” deposit confirmed that this material, due to its high content of aluminosilicates, can be used as raw material for the production of AAM. In order to obtain the product with the best properties, the optimization of the clay calcining process was also carried out. Based on the obtained results, it was found that this process should occur in the range between 750 oC and 800 oC. The use of a lower temperature causes getting a raw material with low metakaolin content which is the main component of materials suitable for alkaline activation processes. On the other hand, higher heat treatment temperatures cause thermal dissociation of large amounts of calcite, which is associated with the release of large amounts of CO2 and the formation of calcium oxide. This compound significantly accelerates the binding process, which consequently often prevents the correct formation of geopolymer mass. The effect of the use of various activators: (i) NaOH, (ii) KOH and (iii) a mixture of KOH to NaOH in a ratio of 10%, 25% and 50% by volume on the compressive strength of the AAM was also analyzed. Obtained results depending on the activator used were in the range from 25 MPa to 40 MPa. These values are comparable with the results obtained for materials produced on the basis of Portland cement, which is one of the most popular building materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alkaline%20activation" title="alkaline activation">alkaline activation</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminosilicates" title=" aluminosilicates"> aluminosilicates</a>, <a href="https://publications.waset.org/abstracts/search?q=calcination" title=" calcination"> calcination</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a> </p> <a href="https://publications.waset.org/abstracts/97862/alkali-activated-materials-based-on-natural-clay-from-raciszyn" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97862.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">153</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> The Impact of Undisturbed Flow Speed on the Correlation of Aerodynamic Coefficients as a Function of the Angle of Attack for the Gyroplane Body</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zbigniew%20Czyz">Zbigniew Czyz</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Skiba"> Krzysztof Skiba</a>, <a href="https://publications.waset.org/abstracts/search?q=Miroslaw%20Wendeker"> Miroslaw Wendeker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper discusses the results of aerodynamic investigation of the Tajfun gyroplane body designed by a Polish company, Aviation Artur Trendak. This gyroplane has been studied as a 1:8 scale model. Scaling objects for aerodynamic investigation is an inherent procedure in any kind of designing. If scaling, the criteria of similarity need to be satisfied. The basic criteria of similarity are geometric, kinematic and dynamic. Despite the results of aerodynamic research are often reduced to aerodynamic coefficients, one should pay attention to how values of coefficients behave if certain criteria are to be satisfied. To satisfy the dynamic criterion, for example, the Reynolds number should be focused on. This is the correlation of inertial to viscous forces. With the multiplied flow speed by the specific dimension as a numerator (with a constant kinematic viscosity coefficient), flow speed in a wind tunnel research should be increased as many times as an object is decreased. The aerodynamic coefficients specified in this research depend on the real forces that act on an object, its specific dimension, medium speed and variations in its density. Rapid prototyping with a 3D printer was applied to create the research object. The research was performed with a T-1 low-speed wind tunnel (its diameter of the measurement volume is 1.5 m) and a six-element aerodynamic internal scales, WDP1, at the Institute of Aviation in Warsaw. This T-1 wind tunnel is low-speed continuous operation with open space measurement. The research covered a number of the selected speeds of undisturbed flow, i.e. V = 20, 30 and 40 m/s, corresponding to the Reynolds numbers (as referred to 1 m) Re = 1.31∙106, 1.96∙106, 2.62∙106 for the angles of attack ranging -15° ≤ α ≤ 20°. Our research resulted in basic aerodynamic characteristics and observing the impact of undisturbed flow speed on the correlation of aerodynamic coefficients as a function of the angle of attack of the gyroplane body. If the speed of undisturbed flow in the wind tunnel changes, the aerodynamic coefficients are significantly impacted. At speed from 20 m/s to 30 m/s, drag coefficient, Cx, changes by 2.4% up to 9.9%, whereas lift coefficient, Cz, changes by -25.5% up to 15.7% if the angle of attack of 0° excluded or by -25.5% up to 236.9% if the angle of attack of 0° included. Within the same speed range, the coefficient of a pitching moment, Cmy, changes by -21.1% up to 7.3% if the angles of attack -15° and -10° excluded or by -142.8% up to 618.4% if the angle of attack -15° and -10° included. These discrepancies in the coefficients of aerodynamic forces definitely need to consider while designing the aircraft. For example, if load of certain aircraft surfaces is calculated, additional correction factors definitely need to be applied. This study allows us to estimate the discrepancies in the aerodynamic forces while scaling the aircraft.

First aid by the Law on National Medical Emergency dated 8 September 2006 as amended, is a set of actions undertaken to save a person at the scene of an accident. In Poland, on the basis of Article 162 of the Criminal Code, we are obliged to provide first aid to the victim. In addition, according to a large part of society, unselfishness towards others in need of help is our moral obligation. The aim of the study was to learn the opinion of the members of Medical Rescue Teams (MRT) of the ‘Meditrans’ Provincial Ambulance and Sanitary Transport Service (PA and STS ‘Meditrans’) in Warsaw on how people react in real situations threatening life or health of the injured person. The study was conducted in the third quarter of 2015 on 335 members of medical rescue teams, including 77 W and 258 M, who provided medical services in the ‘Meditrans’ Provincial Ambulance and Sanitary Transport Service MRT in Warsaw. The research tool was an anonymous questionnaire survey of own design, which consisted of 12 questions: closed, half open and one open question. Respondents were divided into 3 age groups and by individual medical professions (doctor, paramedic, nurse). The straight majority of respondents encountered granting the first aid the event on the spot. However, the frequency of appearing in such proceedings isn’t too high. The first aid has most often been given in the street and in houses. The final audited fairly important element is the reason not to provide first aid by bystanders in the opinion of members of the medical teams. Respondents to this question, which was an open question were asked to name the reason for not taking any action while waiting for an ambulance. Over 50% of respondents could not answer. The most common answers were: fear, lack of knowledge and skills, reluctance, indifference, lack of training, lack of experience and fear that harm. Conclusion: The majority of respondents have encountered instances of first aid provision, but respondents assessed the frequency of such situations as low. Placing the victim in the recovery position is the simplest and most common form of first aid. Therefore, training should be introduced not only on CPR but also in the scope of helping persons in sudden health emergency, who do not have a sudden cardiac arrest. A statement can be formulated, as a main conclusion of the analysis, that only continuous education and in particular practical training will help people to overcome the barrier of their limitations in order to help others. Among the largest group of witnesses providing first aid are the elderly and youth, who are subjected to various forms of education related to first aid provision. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BLS" title="BLS">BLS</a>, <a href="https://publications.waset.org/abstracts/search?q=first%20aid" title=" first aid"> first aid</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20rescue" title=" medical rescue"> medical rescue</a>, <a href="https://publications.waset.org/abstracts/search?q=resuscitation" title=" resuscitation"> resuscitation</a> </p> <a href="https://publications.waset.org/abstracts/89073/quality-assessment-of-the-given-first-aid-on-the-spot-events-in-the-opinion-of-members-of-the-teams-of-the-medical-rescue-in-warsaw-in-poland" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89073.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">7</span> Valorization of Lignocellulosic Wastes– Evaluation of Its Toxicity When Used in Adsorption Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Isabel%20Br%C3%A1s">Isabel Brás</a>, <a href="https://publications.waset.org/abstracts/search?q=Artur%20Figueirinha"> Artur Figueirinha</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Esteves"> Bruno Esteves</a>, <a href="https://publications.waset.org/abstracts/search?q=Lu%C3%ADsa%20P.%20Cruz-Lopes"> Luísa P.

These by-products, specifically almond and hazelnut shells are abundant in Portugal once almond and hazelnuts production is a local important activity. Hazelnut and almond shells have as main constituents lignin, cellulose and hemicelluloses, water soluble extractives and tannins. Along the adsorption of heavy metals from contaminated waters, water soluble compounds can leach from shells and have a negative impact in the environment. Usually, the chemical characterization of treated water by itself may not show environmental impact caused by the discharges when parameters obey to legal quality standards for water. Only biological systems can detect the toxic effects of the water constituents. Therefore, the evaluation of toxicity by biological tests is very important when deciding the suitability for safe water discharge or for irrigation applications. The main purpose of the present work was to assess the potential impacts of waters after been treated for heavy metal removal by hazelnut and almond shells adsorption systems, with short term acute toxicity tests. To conduct the study, water at pH 6 with 25 mg.L-1 of lead, was treated with 10 g of shell per litre of wastewater, for 24 hours. This procedure was followed for each bark. Afterwards the water was collected for toxicological assays; namely bacterial resistance, seed germination, Lemna minor L. test and plant grow. The effect in isolated bacteria strains was determined by disc diffusion method and the germination index of seed was evaluated using lettuce, with temperature and humidity germination control for 7 days. For aquatic higher organism, Lemnas were used with 4 days contact time with shell solutions, in controlled light and temperature. For terrestrial higher plants, biomass production was evaluated after 14 days of tomato germination had occurred in soil, with controlled humidity, light and temperature. Toxicity tests of water treated with shells revealed in some extent effects in the tested organisms, with the test assays showing a close behaviour as the control, leading to the conclusion that its further utilization may not be considered to create a serious risk to the environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lignocellulosic%20wastes" title="lignocellulosic wastes">lignocellulosic wastes</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption"> adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=acute%20toxicity%20tests" title=" acute toxicity tests"> acute toxicity tests</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20assessment" title=" risk assessment"> risk assessment</a> </p> <a href="https://publications.waset.org/abstracts/7853/valorization-of-lignocellulosic-wastes-evaluation-of-its-toxicity-when-used-in-adsorption-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7853.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">367</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Water Ingress into Underground Mine Voids in the Central Rand Goldfields Area, South Africa-Fluid Induced Seismicity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Artur%20Cichowicz">Artur Cichowicz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The last active mine in the Central Rand Goldfields area (50 km x 15 km) ceased operations in 2008. This resulted in the closure of the pumping stations, which previously maintained the underground water level in the mining voids. As a direct consequence of the water being allowed to flood the mine voids, seismic activity has increased directly beneath the populated area of Johannesburg. Monitoring of seismicity in the area has been on-going for over five years using the network of 17 strong ground motion sensors. The objective of the project is to improve strategies for mine closure. The evolution of the seismicity pattern was investigated in detail. Special attention was given to seismic source parameters such as magnitude, scalar seismic moment and static stress drop. Most events are located within historical mine boundaries. The seismicity pattern shows a strong relationship between the presence of the mining void and high levels of seismicity; no seismicity migration patterns were observed outside the areas of old mining. Seven years after the pumping stopped, the evolution of the seismicity has indicated that the area is not yet in equilibrium. The level of seismicity in the area appears to not be decreasing over time since the number of strong events, with Mw magnitudes above 2, is still as high as it was when monitoring began over five years ago. The average rate of seismic deformation is 1.6x1013 Nm/year. Constant seismic deformation was not observed over the last 5 years. The deviation from the average is in the order of 6x10^13 Nm/year, which is a significant deviation. The variation of cumulative seismic moment indicates that a constant deformation rate model is not suitable. Over the most recent five year period, the total cumulative seismic moment released in the Central Rand Basin was 9.0x10^14 Nm. This is equivalent to one earthquake of magnitude 3.9. This is significantly less than what was experienced during the mining operation. Characterization of seismicity triggered by a rising water level in the area can be achieved through the estimation of source parameters. Static stress drop heavily influences ground motion amplitude, which plays an important role in risk assessments of potential seismic hazards in inhabited areas. The observed static stress drop in this study varied from 0.05 MPa to 10 MPa. It was found that large static stress drops could be associated with both small and large events. The temporal evolution of the inter-event time provides an understanding of the physical mechanisms of earthquake interaction. Changes in the characteristics of the inter-event time are produced when a stress change is applied to a group of faults in the region. Results from this study indicate that the fluid-induced source has a shorter inter-event time in comparison to a random distribution. This behaviour corresponds to a clustering of events, in which short recurrence times tend to be close to each other, forming clusters of events. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inter-event%20time" title="inter-event time">inter-event time</a>, <a href="https://publications.waset.org/abstracts/search?q=fluid%20induced%20seismicity" title=" fluid induced seismicity"> fluid induced seismicity</a>, <a href="https://publications.waset.org/abstracts/search?q=mine%20closure" title=" mine closure"> mine closure</a>, <a href="https://publications.waset.org/abstracts/search?q=spectral%20parameters%20of%20seismic%20source" title=" spectral parameters of seismic source"> spectral parameters of seismic source</a> </p> <a href="https://publications.waset.org/abstracts/37688/water-ingress-into-underground-mine-voids-in-the-central-rand-goldfields-area-south-africa-fluid-induced-seismicity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37688.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">285</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">5</span> Concentration of Droplets in a Transient Gas Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Timur%20S.%20Zaripov">Timur S.

The results of recent research, focused on the development of methods for calculating concentration and their implementation in the commercial CFD code, ANSYS Fluent, is presented here. The study is motivated by the investigation of the mixture preparation processes in internal combustion engines with direct injection of fuel sprays. Two methods are used in our analysis; the Fully Lagrangian method (also known as the Osiptsov method) and the Eulerian approach. The Osiptsov method predicts droplet concentrations along path lines by solving the equations for the components of the Jacobian of the Eulerian-Lagrangian transformation. This method significantly decreases the computational requirements as it does not require counting of large numbers of tracked droplets as in the case of the conventional Lagrangian approach. In the Eulerian approach the average droplet velocity is expressed as a function of the carrier phase velocity as an expansion over the droplet response time and transport equation can be solved in the Eulerian form. The advantage of the method is that droplet velocity can be found without solving additional partial differential equations for the droplet velocity field. The predictions from the two approaches were compared in the analysis of the problem of a dilute gas-droplet flow around an infinitely long, circular cylinder. The concentrations of inertial droplets, with Stokes numbers of 0.05, 0.1, 0.2, in steady-state and transient laminar flow conditions, were determined at various Reynolds numbers. In the steady-state case, flows with Reynolds numbers of 1, 10, and 100 were investigated. It has been shown that the results predicted using both methods are almost identical at small Reynolds and Stokes numbers. For larger values of these numbers (Stokes — 0.1, 0.2; Reynolds — 10, 100) the Eulerian approach predicted a wider spread in concentration in the perturbations caused by the cylinder that can be attributed to the averaged droplet velocity field. The transient droplet flow case was investigated for a Reynolds number of 200. Both methods predicted a high droplet concentration in the zones of high strain rate and low concentrations in zones of high vorticity. The maxima of droplet concentration predicted by the Osiptsov method was up to two orders of magnitude greater than that predicted by the Eulerian method; a significant variation for an approach widely used in engineering applications. Based on the results of these comparisons, the Osiptsov method has resulted in a more precise description of the local properties of the inertial droplet flow. The method has been applied to the analysis of the results of experimental observations of a liquid gasoline spray at representative fuel injection pressure conditions. The preliminary results show good qualitative agreement between the predictions of the model and experimental data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internal%20combustion%20engines" title="internal combustion engines">internal combustion engines</a>, <a href="https://publications.waset.org/abstracts/search?q=Eulerian%20approach" title=" Eulerian approach"> Eulerian approach</a>, <a href="https://publications.waset.org/abstracts/search?q=fully%20Lagrangian%20approach" title=" fully Lagrangian approach"> fully Lagrangian approach</a>, <a href="https://publications.waset.org/abstracts/search?q=gasoline%20fuel%20sprays" title=" gasoline fuel sprays"> gasoline fuel sprays</a>, <a href="https://publications.waset.org/abstracts/search?q=droplets%20and%20particle%20concentrations" title=" droplets and particle concentrations"> droplets and particle concentrations</a> </p> <a href="https://publications.waset.org/abstracts/40358/concentration-of-droplets-in-a-transient-gas-flow" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40358.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">257</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Decoding Kinematic Characteristics of Finger Movement from Electrocorticography Using Classical Methods and Deep Convolutional Neural Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ksenia%20Volkova">Ksenia Volkova</a>, <a href="https://publications.waset.org/abstracts/search?q=Artur%20Petrosyan"> Artur Petrosyan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ignatii%20Dubyshkin"> Ignatii Dubyshkin</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexei%20Ossadtchi"> Alexei Ossadtchi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Brain-computer interfaces are a growing research field producing many implementations that find use in different fields and are used for research and practical purposes. Despite the popularity of the implementations using non-invasive neuroimaging methods, radical improvement of the state channel bandwidth and, thus, decoding accuracy is only possible by using invasive techniques. Electrocorticography (ECoG) is a minimally invasive neuroimaging method that provides highly informative brain activity signals, effective analysis of which requires the use of machine learning methods that are able to learn representations of complex patterns. Deep learning is a family of machine learning algorithms that allow learning representations of data with multiple levels of abstraction. This study explores the potential of deep learning approaches for ECoG processing, decoding movement intentions and the perception of proprioceptive information. To obtain synchronous recording of kinematic movement characteristics and corresponding electrical brain activity, a series of experiments were carried out, during which subjects performed finger movements at their own pace. Finger movements were recorded with a three-axis accelerometer, while ECoG was synchronously registered from the electrode strips that were implanted over the contralateral sensorimotor cortex. Then, multichannel ECoG signals were used to track finger movement trajectory characterized by accelerometer signal. This process was carried out both causally and non-causally, using different position of the ECoG data segment with respect to the accelerometer data stream. The recorded data was split into training and testing sets, containing continuous non-overlapping fragments of the multichannel ECoG. A deep convolutional neural network was implemented and trained, using 1-second segments of ECoG data from the training dataset as input. To assess the decoding accuracy, correlation coefficient r between the output of the model and the accelerometer readings was computed. After optimization of hyperparameters and training, the deep learning model allowed reasonably accurate causal decoding of finger movement with correlation coefficient r = 0.8. In contrast, the classical Wiener-filter like approach was able to achieve only 0.56 in the causal decoding mode. In the noncausal case, the traditional approach reached the accuracy of r = 0.69, which may be due to the presence of additional proprioceptive information. This result demonstrates that the deep neural network was able to effectively find a representation of the complex top-down information related to the actual movement rather than proprioception. The sensitivity analysis shows physiologically plausible pictures of the extent to which individual features (channel, wavelet subband) are utilized during the decoding procedure. In conclusion, the results of this study have demonstrated that a combination of a minimally invasive neuroimaging technique such as ECoG and advanced machine learning approaches allows decoding motion with high accuracy. Such setup provides means for control of devices with a large number of degrees of freedom as well as exploratory studies of the complex neural processes underlying movement execution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brain-computer%20interface" title="brain-computer interface">brain-computer interface</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=ECoG" title=" ECoG"> ECoG</a>, <a href="https://publications.waset.org/abstracts/search?q=movement%20decoding" title=" movement decoding"> movement decoding</a>, <a href="https://publications.waset.org/abstracts/search?q=sensorimotor%20cortex" title=" sensorimotor cortex"> sensorimotor cortex</a> </p> <a href="https://publications.waset.org/abstracts/88212/decoding-kinematic-characteristics-of-finger-movement-from-electrocorticography-using-classical-methods-and-deep-convolutional-neural-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88212.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">177</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Neural Correlates of Diminished Humor Comprehension in Schizophrenia: A Functional Magnetic Resonance Imaging Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Przemys%C5%82aw%20Adamczyk">Przemysław Adamczyk</a>, <a href="https://publications.waset.org/abstracts/search?q=Miros%C5%82aw%20Wyczesany"> Mirosław Wyczesany</a>, <a href="https://publications.waset.org/abstracts/search?q=Aleksandra%20Domagalik"> Aleksandra Domagalik</a>, <a href="https://publications.waset.org/abstracts/search?q=Artur%20Daren"> Artur Daren</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamil%20Cepuch"> Kamil Cepuch</a>, <a href="https://publications.waset.org/abstracts/search?q=Piotr%20B%C5%82%C4%85dzi%C5%84ski"> Piotr Błądziński</a>, <a href="https://publications.waset.org/abstracts/search?q=Tadeusz%20Marek"> Tadeusz Marek</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrzej%20Cechnicki"> Andrzej Cechnicki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study aimed at evaluation of neural correlates of humor comprehension impairments observed in schizophrenia. To investigate the nature of this deficit in schizophrenia and to localize cortical areas involved in humor processing we used functional magnetic resonance imaging (fMRI). The study included chronic schizophrenia outpatients (SCH; n=20), and sex, age and education level matched healthy controls (n=20). The task consisted of 60 stories (setup) of which 20 had funny, 20 nonsensical and 20 neutral (not funny) punchlines. After the punchlines were presented, the participants were asked to indicate whether the story was comprehensible (yes/no) and how funny it was (1-9 Likert-type scale). fMRI was performed on a 3T scanner (Magnetom Skyra, Siemens) using 32-channel head coil. Three contrasts in accordance with the three stages of humor processing were analyzed in both groups: abstract vs neutral stories - incongruity detection; funny vs abstract - incongruity resolution; funny vs neutral - elaboration. Additionally, parametric modulation analysis was performed using both subjective ratings separately in order to further differentiate the areas involved in incongruity resolution processing. Statistical analysis for behavioral data used U Mann-Whitney test and Bonferroni’s correction, fMRI data analysis utilized whole-brain voxel-wise t-tests with 10-voxel extent threshold and with Family Wise Error (FWE) correction at alpha = 0.05, or uncorrected at alpha = 0.001. Between group comparisons revealed that the SCH subjects had attenuated activation in: the right superior temporal gyrus in case of irresolvable incongruity processing of nonsensical puns (nonsensical > neutral); the left medial frontal gyrus in case of incongruity resolution processing of funny puns (funny > nonsensical) and the interhemispheric ACC in case of elaboration of funny puns (funny > neutral). Additionally, the SCH group revealed weaker activation during funniness ratings in the left ventro-medial prefrontal cortex, the medial frontal gyrus, the angular and the supramarginal gyrus, and the right temporal pole. In comprehension ratings the SCH group showed suppressed activity in the left superior and medial frontal gyri. Interestingly, these differences were accompanied by protraction of time in both types of rating responses in the SCH group, a lower level of comprehension for funny punchlines and a higher funniness for absurd punchlines. Presented results indicate that, in comparison to healthy controls, schizophrenia is characterized by difficulties in humor processing revealed by longer reaction times, impairments of understanding jokes and finding nonsensical punchlines more funny. This is accompanied by attenuated brain activations, especially in the left fronto-parietal and the right temporal cortices. Disturbances of the humor processing seem to be impaired at the all three stages of the humor comprehension process, from incongruity detection, through its resolution to elaboration. The neural correlates revealed diminished neural activity of the schizophrenia brain, as compared with the control group.

Short-term mitigation strategies have, therefore, been implemented to alleviate the impacts caused by adverse climatic periods. These strategies include foliar application of kaolin, an inert mineral, which has radiation reflection proprieties that decreases stress from excessive heat/radiation absorbed by its leaves, as well as smart irrigation strategies to avoid water stress. However, little is known about the influence of these mitigation measures on grape berries, neither on the photosynthetic activity nor on the photosynthesis-related metabolic profiles of its various tissues. Moreover, the role of fruit photosynthesis on berry quality is poorly understood. The main objective of our work was to assess the effects of kaolin and irrigation treatments on the photosynthetic activity of grape berry tissues (exocarp and seeds) and on their global metabolic profile, also investigating their possible relationship. We therefore collected berries of field-grown plants of the white grape variety Alvarinho from two distinct microclimates, i.e. from clusters exposed to high light (HL, 150 µmol photons m⁻² s⁻¹) and low light (LL, 50 µmol photons m⁻² s⁻¹), from both kaolin and non-kaolin (control) treated plants at three fruit developmental stages (green, véraison and mature). Plant irrigation was applied after harvesting the green berries, which also enabled comparison of véraison and mature berries from irrigated and non-irrigated growth conditions. Photosynthesis was assessed by pulse amplitude modulated chlorophyll fluorescence imaging analysis, and the metabolite profile of both tissues was assessed by complementary metabolomics approaches. Foliar kaolin application resulted in, for instance, an increased photosynthetic activity of the exocarp of LL-grown berries at green developmental stage, as compared to the control non-kaolin treatment, with a concomitant increase in the levels of several lipid-soluble isoprenoids (chlorophylls, carotenoids, and tocopherols). The exocarp of mature berries grown at HL microclimate on kaolin-sprayed non-irrigated plants had higher total sugar levels content than all other treatments, suggesting that foliar application of this mineral results in an increased accumulation of photoassimilates in mature berries. Unbiased liquid chromatography-mass spectrometry-based profiling of semi-polar compounds followed by ASCA (ANOVA simultaneous component analysis) and ANOVA statistical analysis indicated that kaolin had no or inconsistent effect on the flavonoid and phenylpropanoid composition in both seed and exocarp at any developmental stage; in contrast, both microclimate and irrigation influenced the level of several of these compounds depending on berry ripening stage. Overall, our study provides more insight into the effects of mitigation strategies on berry tissue photosynthesis and phytochemistry, under contrasting conditions of cluster light microclimate. We hope that this may contribute to develop sustainable management in vineyards and to maintain grape berries and wines with high quality even at increasing abiotic stress challenges. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=grape%20berry%20tissues" title=" grape berry tissues"> grape berry tissues</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolomics" title=" metabolomics"> metabolomics</a>, <a href="https://publications.waset.org/abstracts/search?q=mitigation%20strategies" title=" mitigation strategies"> mitigation strategies</a> </p> <a href="https://publications.waset.org/abstracts/113080/phytochemicals-and-photosynthesis-of-grape-berry-exocarp-and-seed-vitis-vinifera-cv-alvarinho-effects-of-foliar-kaolin-and-irrigation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113080.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">1</span> Application of Large Eddy Simulation-Immersed Boundary Volume Penalization Method for Heat and Mass Transfer in Granular Layers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Artur%20Tyliszczak">Artur Tyliszczak</a>, <a href="https://publications.waset.org/abstracts/search?q=Ewa%20Szymanek"> Ewa Szymanek</a>, <a href="https://publications.waset.org/abstracts/search?q=Maciej%20Marek"> Maciej Marek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flow through granular materials is important to a vast array of industries, for instance in construction industry where granular layers are used for bulkheads and isolators, in chemical engineering and catalytic reactors where large surfaces of packed granular beds intensify chemical reactions, or in energy production systems, where granulates are promising materials for heat storage and heat transfer media. Despite the common usage of granulates and extensive research performed in this field, phenomena occurring between granular solid elements or between solids and fluid are still not fully understood. In the present work we analyze the heat exchange process between the flowing medium (gas, liquid) and solid material inside the granular layers. We consider them as a composite of isolated solid elements and inter-granular spaces in which a gas or liquid can flow. The structure of the layer is controlled by shapes of particular granular elements (e.g., spheres, cylinders, cubes, Raschig rings), its spatial distribution or effective characteristic dimension (total volume or surface area). We will analyze to what extent alteration of these parameters influences on flow characteristics (turbulent intensity, mixing efficiency, heat transfer) inside the layer and behind it. Analysis of flow inside granular layers is very complicated because the use of classical experimental techniques (LDA, PIV, fibber probes) inside the layers is practically impossible, whereas the use of probes (e.g. thermocouples, Pitot tubes) requires drilling of holes inside the solid material. Hence, measurements of the flow inside granular layers are usually performed using for instance advanced X-ray tomography. In this respect, theoretical or numerical analyses of flow inside granulates seem crucial. Application of discrete element methods in combination with the classical finite volume/finite difference approaches is problematic as a mesh generation process for complex granular material can be very arduous. A good alternative for simulation of flow in complex domains is an immersed boundary-volume penalization (IB-VP) in which the computational meshes have simple Cartesian structure and impact of solid objects on the fluid is mimicked by source terms added to the Navier-Stokes and energy equations. The present paper focuses on application of the IB-VP method combined with large eddy simulation (LES). The flow solver used in this work is a high-order code (SAILOR), which was used previously in various studies, including laminar/turbulent transition in free flows and also for flows in wavy channels, wavy pipes and over various shape obstacles. In these cases a formal order of approximation turned out to be in between 1 and 2, depending on the test case. The current research concentrates on analyses of the flows in dense granular layers with elements distributed in a deterministic regular manner and validation of the results obtained using LES-IB method and body-fitted approach. The comparisons are very promising and show very good agreement. It is found that the size, number of elements and their distribution have huge impact on the obtained results. Ordering of the granular elements (or lack of it) affects both the pressure drop and efficiency of the heat transfer as it significantly changes mixing process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=granular%20layers" title="granular layers">granular layers</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title=" heat transfer"> heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=immersed%20boundary%20method" title=" immersed boundary method"> immersed boundary method</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulations" title=" numerical simulations"> numerical simulations</a> </p> <a href="https://publications.waset.org/abstracts/116874/application-of-large-eddy-simulation-immersed-boundary-volume-penalization-method-for-heat-and-mass-transfer-in-granular-layers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116874.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">137</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">© 2024 World Academy of Science, Engineering and Technology</div> </div> </footer> <a href="javascript:" id="return-to-top"><i class="fas fa-arrow-up"></i></a> <div class="modal" id="modal-template"> <div class="modal-dialog"> <div class="modal-content"> <div class="row m-0 mt-1"> <div class="col-md-12"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> </div> </div> <div class="modal-body"></div> </div> </div> </div> <script src="https://cdn.waset.org/static/plugins/jquery-3.3.1.min.js"></script> <script src="https://cdn.waset.org/static/plugins/bootstrap-4.2.1/js/bootstrap.bundle.min.js"></script> <script src="https://cdn.waset.org/static/js/site.js?v=150220211556"></script> <script> jQuery(document).ready(function() { /*jQuery.get("https://publications.waset.org/xhr/user-menu", function (response) { jQuery('#mainNavMenu').append(response);
