</p> <p class="card-text"><strong>Abstract:</strong></p> Cigarette smoking is the main cause and the most common risk factor for both COPD and lung cancer. In our previous studies, we proved that caspase-11 in mice and its human analogue, caspase-4, are involved in lung carcinogenesis and that AIM2 inflammasome might play a pro-cancerous role in lung cancer. Therefore, the aim of this study was to investigate potential crosstalk between COPD and lung cancer, focusing on AIM2 and caspase-11-dependent inflammasome signaling pathway. To mimic COPD, we took advantage of an experimental first-hand smoking mouse model and, to confirm what was observed in mice, we used human samples of lung adenocarcinoma patients stratified according to the smoking and COPD status. We demonstrated that smoke exposure led to emphysema-like features, bronchial tone impairment, and release of IL-1-like cytokines (IL-1α, IL-1β, IL-33, IL-18) in a caspase-1 independent manner in C57Bl/6N. Rather, a dysfunctional caspase-11 in smoke-exposed 129Sv mice was associated to lower bronchial inflammation, collagen deposition, and IL-1-like inflammation. In addition, for the first time, we found that AIM2 inflammasome is involved in lung inflammation in smoking and COPD, in that its expression was higher in smoke-exposed C57Bl/6N compared to 129Sv smoking mice, who instead did not show any alteration of AIM2 in both macrophages and dendritic cells. Moreover, we found that AIM2 expression in the cancerous tissue, albeit higher than non-cancerous tissue, was not statistically different according to the COPD and smoking status. Instead, the higher expression of AIM2 in non-cancerous tissue of smoker COPD patients than smokers who did not have COPD was correlated to a higher hazard ratio of poor survival rate than patients who presented lower levels of AIM2. In conclusion, our data highlight that caspase-11 in mice is associated to smoke-induced lung latent inflammation which could drive the establishment of lung cancer, and that AIM2 inflammasome plays a role at the crosstalk between smoking/COPD and lung adenocarcinoma in that its higher presence is correlated to lower survival rate of smoker COPD adenocarcinoma. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COPD" title="COPD">COPD</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammasome" title=" inflammasome"> inflammasome</a>, <a href="https://publications.waset.org/abstracts/search?q=lung%20cancer" title=" lung cancer"> lung cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=lung%20inflammation" title=" lung inflammation"> lung inflammation</a>, <a href="https://publications.waset.org/abstracts/search?q=smoke" title=" smoke"> smoke</a> </p> <a href="https://publications.waset.org/abstracts/143446/caspase-11-and-aim2-inflammasome-are-involved-in-smoking-induced-copd-and-lung-adenocarcinoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143446.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">156</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> Intracellular Sphingosine-1-Phosphate Receptor 3 Contributes to Lung Tumor Cell Proliferation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michela%20Terlizzi">Michela Terlizzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiara%20Colarusso"> Chiara Colarusso</a>, <a href="https://publications.waset.org/abstracts/search?q=Aldo%20Pinto"> Aldo Pinto</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosalinda%20Sorrentino"> Rosalinda Sorrentino</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sphingosine-1-phosphate (S1P) is a membrane-derived bioactive phospholipid exerting a multitude of effects on respiratory cell physiology and pathology through five S1P receptors (S1PR1-5). Higher levels of S1P have been registered in a broad range of respiratory diseases, including inflammatory disorders and cancer, although its exact role is still elusive. Based on our previous study in which we found that S1P/S1PR3 is involved in an inflammatory pattern via the activation of Toll-like Receptor 9 (TLR9), highly expressed on lung cancer cells, the main goal of the current study was to better understand the involvement of S1P/S1PR3 pathway/signaling during lung carcinogenesis, taking advantage of a mouse model of first-hand smoke exposure and of carcinogen-induced lung cancer. We used human samples of Non-Small Cell Lung Cancer (NSCLC), a mouse model of first-hand smoking, and of Benzo(a)pyrene (BaP)-induced tumor-bearing mice and A549 lung adenocarcinoma cells. We found that the intranuclear, but not the membrane, localization of S1PR3 was associated to the proliferation of lung adenocarcinoma cells, the mechanism that was correlated to human and mouse samples of smoke-exposure and carcinogen-induced lung cancer, which were characterized by higher utilization of S1P. Indeed, the inhibition of the membrane S1PR3 did not alter tumor cell proliferation after TLR9 activation. Instead, according to the nuclear localization of sphingosine kinase (SPHK) II, the enzyme responsible for the catalysis of the S1P last step synthesis, the inhibition of the kinase completely blocked the endogenous S1P-induced tumor cell proliferation. These results prove that the endogenous TLR9-induced S1P can on one side favor pro-inflammatory mechanisms in the tumor microenvironment via the activation of cell surface receptors, but on the other tumor progression via the nuclear S1PR3/SPHK II axis, highlighting a novel molecular mechanism that identifies S1P as one of the crucial mediators for lung carcinogenesis-associated inflammatory processes and that could provide differential therapeutic approaches especially in non-responsive lung cancer patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sphingosine-1-phosphate%20%28S1P%29" title="sphingosine-1-phosphate (S1P)">sphingosine-1-phosphate (S1P)</a>, <a href="https://publications.waset.org/abstracts/search?q=S1P%20Receptor%203%20%28S1PR3%29" title=" S1P Receptor 3 (S1PR3)"> S1P Receptor 3 (S1PR3)</a>, <a href="https://publications.waset.org/abstracts/search?q=smoking-mice" title=" smoking-mice"> smoking-mice</a>, <a href="https://publications.waset.org/abstracts/search?q=lung%20inflammation" title=" lung inflammation"> lung inflammation</a>, <a href="https://publications.waset.org/abstracts/search?q=lung%20cancer" title=" lung cancer"> lung cancer</a> </p> <a href="https://publications.waset.org/abstracts/143416/intracellular-sphingosine-1-phosphate-receptor-3-contributes-to-lung-tumor-cell-proliferation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143416.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">201</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> Spatial Element Importance and Its Relation to Characters’ Emotions and Self Awareness in Michela Murgia’s Collection of Short Stories Tre Ciotole. Rituali per Un Anno DI Crisi</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nikica%20Mihaljevi%C4%87">Nikica Mihaljević</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Published in 2023, "Tre ciotole. Rituali per un anno di crisi" is a collection of short stories completely disconnected from one another in regard to topics and the representation of characters. However, these short stories complete and somehow continue each other in a particular way. The book happens to be Murgia's last book, as the author died a few months later after the book's publication and it appears as a kind of summary of all her previous literary works. Namely, in her previous publications, Murgia already stressed certain characters' particularities, such as solitude and alienation from others, which are at the center of attention in this literary work, too. What all the stories present in "Tre ciotole" have in common is the dealing with characters' identity and self-awareness through the challenges they confront and the way the characters live their emotions in relation to the surrounding space. Although the challenges seem similar, the spatial element around the characters is different, but it confirms each time that characters' emotions, and, consequently, their self-awareness, can be formed and built only through their connection and relation to the surrounding space. In that way, the reader creates an imaginary network of complex relations among characters in all the short stories, which gives him/her the opportunity to search for a way to break out of the usual patterns that tend to be repeated while characters focus on building self-awareness. The aim of the paper is to determine and analyze the role of spatial elements in the creation of characters' emotions and in the process of self-awareness. As the spatial element changes or gets transformed and/or substituted, in the same way, we notice the arise of the unconscious desire for self-harm in the characters, which damages their self-awareness. Namely, the characters face a crisis that they cannot control by inventing other types of crises that can be controlled. That happens to be their way of acting in order to find the way out of the identity crisis. Consequently, we expect that the results of the analysis point out the similarities in the short stories in characters' depiction as well as to show the extent to which the characters' identities depend on the surrounding space in each short story. In this way, the results will highlight the importance of spatial elements in characters' identity formation in Michela Murgia's short stories and also summarize the importance of the whole Murgia's literary opus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Italian%20literature" title="Italian literature">Italian literature</a>, <a href="https://publications.waset.org/abstracts/search?q=short%20stories" title=" short stories"> short stories</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20element" title=" spatial element"> spatial element</a>, <a href="https://publications.waset.org/abstracts/search?q=emotions" title=" emotions"> emotions</a>, <a href="https://publications.waset.org/abstracts/search?q=characters" title=" characters"> characters</a> </p> <a href="https://publications.waset.org/abstracts/179155/spatial-element-importance-and-its-relation-to-characters-emotions-and-self-awareness-in-michela-murgias-collection-of-short-stories-tre-ciotole-rituali-per-un-anno-di-crisi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179155.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">52</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> An Evaluation of Existing Models to Smart Cities Development Around the World</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aqsa%20Mehmood">Aqsa Mehmood</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ali%20Tahir"> Muhammad Ali Tahir</a>, <a href="https://publications.waset.org/abstracts/search?q=Hafiz%20Syed%20Hamid%20Arshad"> Hafiz Syed Hamid Arshad</a>, <a href="https://publications.waset.org/abstracts/search?q=Salman%20Atif"> Salman Atif</a>, <a href="https://publications.waset.org/abstracts/search?q=Ejaz%20Hussain"> Ejaz Hussain</a>, <a href="https://publications.waset.org/abstracts/search?q=Gavin%20McArdle"> Gavin McArdle</a>, <a href="https://publications.waset.org/abstracts/search?q=Michela%20Bertolotto"> Michela Bertolotto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The evolution of smart cities in recent years has been developing dramatically. As urbanization increases, the demand for big data analytics and digital technology-based solutions for cities has also increased. Many cities around the world have now planned to focus on smart cities. To obtain a systematic overview of smart city models, we carried out a bibliometric analysis in the context of seven regions of the world to understand the main dimensions that characterize smart cities. This paper analyses articles published between 2017 and 2021 that were captured from Web of Science and Scopus. Specifically, we investigated publication trends to highlight the research gaps and current developments in smart cities research. Our survey provides helpful insights into the geographical distribution of smart city publications with respect to regions of the world and explores the current key topics relevant to smart cities and the co-occurrences of keywords used in these publications. A systematic literature review and keyword analysis were performed. The results have focused on identifying future directions in smart city development, including smart citizens, ISO standards, Open Geospatial Consortium and the sustainability factor of smart cities. This article will assist researchers and urban planners in understanding the latest trends in research and highlight the aspects which need further attention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smart%20cities" title="smart cities">smart cities</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=regions" title=" regions"> regions</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20development" title=" urban development"> urban development</a>, <a href="https://publications.waset.org/abstracts/search?q=VOS%20viewer" title=" VOS viewer"> VOS viewer</a>, <a href="https://publications.waset.org/abstracts/search?q=research%20trends" title=" research trends"> research trends</a> </p> <a href="https://publications.waset.org/abstracts/168563/an-evaluation-of-existing-models-to-smart-cities-development-around-the-world" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168563.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">10</span> Stigma Associated with Invisible Disabilities and Its Effect on Intended Disclosure in the Workplace</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jessica%20Lynne%20Hicksted">Jessica Lynne Hicksted</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Disability discrimination is a long-standing issue that, despite protections, continues to result in unemployment, underemployment, and lack of advancement for disabled persons. Visible stigma is researched substantially; however, less is known about the impact of stigma associated with identities that can be concealed. Although researchers have investigated this issue, currently there is no tool to measure this phenomenon. The purpose of this quantitative study was to create and validate a new tool to measure stigma associated with invisible disabilities. The study is grounded by Roberts’ conceptual model of professional image construction integrating social identity, impression management, and organizational behavior; Meisenbach’s stigma management communication theory addressing the vulnerabilities and resilience to stigma communication by focusing on how individuals encounter and react to perceived stigmas; and Kelley and Michela’s causal attribution theory. Participants included 1,412 adults in the United States 18 years or older currently employed or who have been employed within the last 5 years. Confirmatory factor analysis of the new Workplace Invisible Disabilities Experience scale showed excellent fit of the factor structure to the data, X₂/df = 1.855, CFI = .955, RMSEA = .045, p = .0001. The scale has three subscales, Ableism, Advocacy, and Acceptance, with excellent internal consistency reliability. Total score, Advocacy, and Acceptance were associated with intention to disclose. Implications for positive social change include helping organizations to understand the extent of invisible disability stigma that can help improve workplace performance and satisfaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=invisible%20disabilities" title="invisible disabilities">invisible disabilities</a>, <a href="https://publications.waset.org/abstracts/search?q=accommodations" title=" accommodations"> accommodations</a>, <a href="https://publications.waset.org/abstracts/search?q=acceptance" title=" acceptance"> acceptance</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20change" title=" social change"> social change</a>, <a href="https://publications.waset.org/abstracts/search?q=workplace%20inclusion" title=" workplace inclusion"> workplace inclusion</a> </p> <a href="https://publications.waset.org/abstracts/174374/stigma-associated-with-invisible-disabilities-and-its-effect-on-intended-disclosure-in-the-workplace" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174374.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">70</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> Self-Esteem and Emotional Intelligence’s Association to Nutritional Status in Adolescent Schoolchildren in Chile</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peter%20Mc%20Coll">Peter Mc Coll</a>, <a href="https://publications.waset.org/abstracts/search?q=Alberto%20Caro"> Alberto Caro</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiara%20Gandolfo"> Chiara Gandolfo</a>, <a href="https://publications.waset.org/abstracts/search?q=Montserrat%20Labbe"> Montserrat Labbe</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisca%20Schnaidt"> Francisca Schnaidt</a>, <a href="https://publications.waset.org/abstracts/search?q=Michela%20Palazzi"> Michela Palazzi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Self-esteem and emotional intelligence are variables that are related to people's nutritional status. Self-esteem may be at low levels in people living with obesity, while emotional intelligence can play an important role in the way people living with obesity cope. The objective of the study was to measure the association between self-esteem and emotional intelligence to nutritional status in adolescent population. Methodology: A cross-sectional study was carried out with 179 adolescent schoolchildren between 13 and 19 years old from a public school. The objective was to evaluate nutritional status; weight and height were measured by calculating the body mass index and Z score. Self-esteem was evaluated using the Coopersmith Self-esteem Inventory adapted by Brinkmann and Segure. Emotional intelligence was measured using the Emotional Quotient Inventory: short, by Bar On, adapted questionnaire, translated into Spanish by López Zafra. For statistical analysis: Pearson's Chi-square test, Pearson's correlation, and odd ratio calculation were used, with a p value at a significance level < 5%. Results: The study group was composed of 71% female and 29% male. The nutritional status was distributed as eutrophic 41.9%, overweight 20.1%, and obesity 21.1%. In relation to self-esteem, 44.1% presented low and very low levels, without differences by gender. Emotional intelligence was distributed: low 3.4%, medium 81%, and high 13.4% -no differences according to gender. The association between nutritional status (overweight and obesity) with low and very low self-esteem, an odds ratio of 2.5 (95% CI 1.12 – 5.59) was obtained with a p-value = 0.02. The correlation analysis between the intrapersonal sub-dimension emotional intelligence scores and the Z score of nutritional status presented a negative correlation of r = - 0.209 with a p-value < 0.005. The correlation between emotional intelligence subdimension stress management with Z score presented a positive correlation of r = 0.0161 with a p-value < 0.05. In conclusion, the group of adolescents studied had a high prevalence of overweight and obesity, a high prevalence of low self-esteem, and a high prevalence of average emotional intelligence. Overweight and obese adolescents were 2.5 times more likely to have low self-esteem. As overweight and obesity increase, self-esteem decreases, and the ability to manage stress increases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=self-esteem" title="self-esteem">self-esteem</a>, <a href="https://publications.waset.org/abstracts/search?q=emotional%20intelligence" title=" emotional intelligence"> emotional intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=obesity" title=" obesity"> obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=adolescent" title=" adolescent"> adolescent</a>, <a href="https://publications.waset.org/abstracts/search?q=nutritional%20status" title=" nutritional status"> nutritional status</a> </p> <a href="https://publications.waset.org/abstracts/183439/self-esteem-and-emotional-intelligences-association-to-nutritional-status-in-adolescent-schoolchildren-in-chile" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183439.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">59</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Basil Plants Attract and Benefit Generalist Lacewing Predator Ceraeochrysa cubana Hagen (Neuroptera: Chrysopidae) by Providing Nutritional Resources</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michela%20C.%20Batista%20Matos">Michela C.

Attractive plants could be used as crop companion plants to promote biological control of pests. In order to select such plants for future use in horticulture fields, we assessed the attractiveness of the aromatic plants Ocimum basilicum L. (basil), Mentha piperita L. (peppermint), Melissa officinalis L. (lemon balm) and Cordia verbenacea DC (black sage) to adults of the generalist lacewing predator Ceraeochrysa cubana Hagen (Neuroptera: Chrysopidae). This predator is commonly found in agroecosystems in Brazil and it feeds on aphids, mites, small caterpillars, insect eggs and scales. We further tested the effect of these plant species on the survival, development and oviposition of C. cubana. Finally, we evaluated the survival of larvae and adults of C. cubana when only flowers of basil were offered. Females of C. cubana were attracted to basil but not to the remaining aromatic plants. Larvae survival was higher when individuals had access only to basil leaf than when they had access to peppermint, lemon balm, black sage or water. Adult survival on leaf treatments and on water was no longer than three days. Flowers of basil enhanced predator larvae survival, yet they did not reach adulthood. Adults fed on basil flowers lived longer compared with water, but they did not reproduce. Basil is a promising aromatic plant species to be considered for conservation biological control programs. Besides being attractive to adults of the generalist predator, it benefits larvae and adults by providing nutritional resources when prey or other resources are absent.

They are widely used in theory of knots and links for studying the finite type invariants, whereas in molecular biology one important motivation to study chord diagrams is to deal with the problem of RNA structure prediction. An RNA molecule is a linear polymer, referred to as the backbone, that consists of four types of nucleotides. Each nucleotide is represented by a point, whereas each chord of the diagram stands for one interaction for Watson-Crick base pairs between two nonconsecutive nucleotides. A chord diagram is an oriented circle with a set of n pairs of distinct points, considered up to orientation preserving diffeomorphisms of the circle. A linear chord diagram (LCD) is a special kind of graph obtained cutting the oriented circle of a chord diagram. It consists of a line segment, called its backbone, to which are attached a number of chords with distinct endpoints. There is a natural fattening on any linear chord diagram; the backbone lies on the real axis, while all the chords are in the upper half-plane. Each linear chord diagram has a natural genus of its associated surface. To each chord diagram and linear chord diagram, it is possible to associate the intersection graph. It consists of a graph whose vertices correspond to the chords of the diagram, whereas the chord intersections are represented by a connection between the vertices. Such intersection graph carries a lot of information about the diagram. Our goal is to define an LCD equivalence class in terms of identity of intersection graphs, from which many chord diagram invariants depend. For studying these invariants, we introduce a new representation of Linear Chord Diagrams based on a set of appropriate topological operators that permits to model LCD in terms of the relations among chords. Such set is composed of: crossing, nesting, and concatenations. The crossing operator is able to generate the whole space of linear chord diagrams, and a multiple context free grammar able to uniquely generate each LDC starting from a linear chord diagram adding a chord for each production of the grammar is defined. In other words, it allows to associate a unique algebraic term to each linear chord diagram, while the remaining operators allow to rewrite the term throughout a set of appropriate rewriting rules. Such rules define an LCD equivalence class in terms of the identity of intersection graphs. Starting from a modelled RNA molecule and the linear chord, some authors proposed a topological classification and folding. Our LCD equivalence class could contribute to the RNA folding problem leading to the definition of an algorithm that calculates the free energy of the molecule more accurately respect to the existing ones. Such LCD equivalence class could be useful to obtain a more accurate estimate of link between the crossing number and the topological genus and to study the relation among other invariants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chord%20diagrams" title="chord diagrams">chord diagrams</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20chord%20diagram" title=" linear chord diagram"> linear chord diagram</a>, <a href="https://publications.waset.org/abstracts/search?q=equivalence%20class" title=" equivalence class"> equivalence class</a>, <a href="https://publications.waset.org/abstracts/search?q=topological%20language" title=" topological language"> topological language</a> </p> <a href="https://publications.waset.org/abstracts/77566/topological-language-for-classifying-linear-chord-diagrams-via-intersection-graphs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77566.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">201</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> Aerosol Characterization in a Coastal Urban Area in Rimini, Italy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dimitri%20Bacco">Dimitri Bacco</a>, <a href="https://publications.waset.org/abstracts/search?q=Arianna%20Trentini"> Arianna Trentini</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabiana%20Scotto"> Fabiana Scotto</a>, <a href="https://publications.waset.org/abstracts/search?q=Flavio%20Rovere"> Flavio Rovere</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniele%20Foscoli"> Daniele Foscoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Cinzia%20Para"> Cinzia Para</a>, <a href="https://publications.waset.org/abstracts/search?q=Paolo%20Veronesi"> Paolo Veronesi</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Sandrini"> Silvia Sandrini</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Zigola"> Claudia Zigola</a>, <a href="https://publications.waset.org/abstracts/search?q=Michela%20Comandini"> Michela Comandini</a>, <a href="https://publications.waset.org/abstracts/search?q=Marilena%20Montalti"> Marilena Montalti</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Zamagni"> Marco Zamagni</a>, <a href="https://publications.waset.org/abstracts/search?q=Vanes%20Poluzzi"> Vanes Poluzzi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Po Valley, in the north of Italy, is one of the most polluted areas in Europe. The air quality of the area is linked not only to anthropic activities but also to its geographical characteristics and stagnant weather conditions with frequent inversions, especially in the cold season. Even the coastal areas present high values of particulate matter (PM10 and PM2.5) because the area closed between the Adriatic Sea and the Apennines does not favor the dispersion of air pollutants. The aim of the present work was to identify the main sources of particulate matter in Rimini, a tourist city in northern Italy. Two sampling campaigns were carried out in 2018, one in winter (60 days) and one in summer (30 days), in 4 sites: an urban background, a city hotspot, a suburban background, and a rural background. The samples are characterized by the concentration of the ionic composition of the particulates and of the main a hydro-sugars, in particular levoglucosan, a marker of the biomass burning, because one of the most important anthropogenic sources in the area, both in the winter and surprisingly even in the summer, is the biomass burning. Furthermore, three sampling points were chosen in order to maximize the contribution of a specific biomass source: a point in a residential area (domestic cooking and domestic heating), a point in the agricultural area (weed fires), and a point in the tourist area (restaurant cooking). In these sites, the analyzes were enriched with the quantification of the carbonaceous component (organic and elemental carbon) and with measurement of the particle number concentration and aerosol size distribution (6 - 600 nm). The results showed a very significant impact of the combustion of biomass due to domestic heating in the winter period, even though many intense peaks were found attributable to episodic wood fires. In the summer season, however, an appreciable signal was measured linked to the combustion of biomass, although much less intense than in winter, attributable to domestic cooking activities. Further interesting results were the verification of the total absence of sea salt's contribution in the particulate with the lower diameter (PM2.5), and while in the PM10, the contribution becomes appreciable only in particular wind conditions (high wind from north, north-east). Finally, it is interesting to note that in a small town, like Rimini, in summer, the traffic source seems to be even more relevant than that measured in a much larger city (Bologna) due to tourism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerosol" title="aerosol">aerosol</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass%20burning" title=" biomass burning"> biomass burning</a>, <a href="https://publications.waset.org/abstracts/search?q=seacoast" title=" seacoast"> seacoast</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20area" title=" urban area"> urban area</a> </p> <a href="https://publications.waset.org/abstracts/117769/aerosol-characterization-in-a-coastal-urban-area-in-rimini-italy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117769.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">128</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> Immersive and Non-Immersive Virtual Reality Applied to the Cervical Spine Assessment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pawel%20Kiper">Pawel Kiper</a>, <a href="https://publications.waset.org/abstracts/search?q=Alfonc%20Baba"> Alfonc Baba</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Alhelou"> Mahmoud Alhelou</a>, <a href="https://publications.waset.org/abstracts/search?q=Giorgia%20Pregnolato"> Giorgia Pregnolato</a>, <a href="https://publications.waset.org/abstracts/search?q=Michela%20Agostini"> Michela Agostini</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Turolla"> Andrea Turolla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Impairment of cervical spine mobility is often related to pain triggered by musculoskeletal disorders or direct traumatic injuries of the spine. To date, these disorders are assessed with goniometers and inclinometers, which are the most popular devices used in clinical settings. Nevertheless, these technologies usually allow measurement of no more than two-dimensional range of motion (ROM) quotes in static conditions. Conversely, the wide use of motion tracking systems able to measure 3 to 6 degrees of freedom dynamically, while performing standard ROM assessment, are limited due to technical complexities in preparing the setup and high costs. Thus, motion tracking systems are primarily used in research. These systems are an integral part of virtual reality (VR) technologies, which can be used for measuring spine mobility. To our knowledge, the accuracy of VR measure has not yet been studied within virtual environments. Thus, the aim of this study was to test the reliability of a protocol for the assessment of sensorimotor function of the cervical spine in a population of healthy subjects and to compare whether using immersive or non-immersive VR for visualization affects the performance. Both VR assessments consisted of the same five exercises and random sequence determined which of the environments (i.e. immersive or non-immersive) was used as first assessment. Subjects were asked to perform head rotation (right and left), flexion, extension and lateral flexion (right and left side bending). Each movement was executed five times. Moreover, the participants were invited to perform head reaching movements i.e. head movements toward 8 targets placed along a circular perimeter each 45°, visualized one-by-one in random order. Finally, head repositioning movement was obtained by head movement toward the same 8 targets as for reaching and following reposition to the start point. Thus, each participant performed 46 tasks during assessment. Main measures were: ROM of rotation, flexion, extension, lateral flexion and complete kinematics of the cervical spine (i.e. number of completed targets, time of execution (seconds), spatial length (cm), angle distance (°), jerk). Thirty-five healthy participants (i.e. 14 males and 21 females, mean age 28.4±6.47) were recruited for the cervical spine assessment with immersive and non-immersive VR environments. Comparison analysis demonstrated that: head right rotation (p=0.027), extension (p=0.047), flexion (p=0.000), time (p=0.001), spatial length (p=0.004), jerk target (p=0.032), trajectory repositioning (p=0.003), and jerk target repositioning (p=0.007) were significantly better in immersive than non-immersive VR. A regression model showed that assessment in immersive VR was influenced by height, trajectory repositioning (p<0.05), and handedness (p<0.05), whereas in non-immersive VR performance was influenced by height, jerk target (p=0.002), head extension, jerk target repositioning (p=0.002), and by age, head flex/ext, trajectory repositioning, and weight (p=0.040). The results of this study showed higher accuracy of cervical spine assessment when executed in immersive VR. The assessment of ROM and kinematics of the cervical spine can be affected by independent and dependent variables in both immersive and non-immersive VR settings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=virtual%20reality" title="virtual reality">virtual reality</a>, <a href="https://publications.waset.org/abstracts/search?q=cervical%20spine" title=" cervical spine"> cervical spine</a>, <a href="https://publications.waset.org/abstracts/search?q=motion%20analysis" title=" motion analysis"> motion analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=range%20of%20motion" title=" range of motion"> range of motion</a>, <a href="https://publications.waset.org/abstracts/search?q=measurement%20validity" title=" measurement validity"> measurement validity</a> </p> <a href="https://publications.waset.org/abstracts/95192/immersive-and-non-immersive-virtual-reality-applied-to-the-cervical-spine-assessment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95192.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">166</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> Polarization as a Proxy of Misinformation Spreading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michela%20Del%20Vicario">Michela Del Vicario</a>, <a href="https://publications.waset.org/abstracts/search?q=Walter%20Quattrociocchi"> Walter Quattrociocchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Scala"> Antonio Scala</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Luc%C3%ADa%20Schmidt"> Ana Lucía Schmidt</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabiana%20Zollo"> Fabiana Zollo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Information, rumors, and debates may shape and impact public opinion heavily. In the latest years, several concerns have been expressed about social influence on the Internet and the outcome that online debates might have on real-world processes. Indeed, on online social networks users tend to select information that is coherent to their system of beliefs and to form groups of like-minded people –i.e., echo chambers– where they reinforce and polarize their opinions. In this way, the potential benefits coming from the exposure to different points of view may be reduced dramatically, and individuals' views may become more and more extreme. Such a context fosters misinformation spreading, which has always represented a socio-political and economic risk. The persistence of unsubstantiated rumors –e.g., the hypothetical and hazardous link between vaccines and autism– suggests that social media do have the power to misinform, manipulate, or control public opinion. As an example, current approaches such as debunking efforts or algorithmic-driven solutions based on the reputation of the source seem to prove ineffective against collective superstition. Indeed, experimental evidence shows that confirmatory information gets accepted even when containing deliberately false claims while dissenting information is mainly ignored, influences users’ emotions negatively and may even increase group polarization. Moreover, confirmation bias has been shown to play a pivotal role in information cascades, posing serious warnings about the efficacy of current debunking efforts. Nevertheless, mitigation strategies have to be adopted. To generalize the problem and to better understand social dynamics behind information spreading, in this work we rely on a tight quantitative analysis to investigate the behavior of more than 300M users w.r.t. news consumption on Facebook over a time span of six years (2010-2015). Through a massive analysis on 920 news outlets pages, we are able to characterize the anatomy of news consumption on a global and international scale. We show that users tend to focus on a limited set of pages (selective exposure) eliciting a sharp and polarized community structure among news outlets. Moreover, we find similar patterns around the Brexit –the British referendum to leave the European Union– debate, where we observe the spontaneous emergence of two well segregated and polarized groups of users around news outlets. Our findings provide interesting insights into the determinants of polarization and the evolution of core narratives on online debating. Our main aim is to understand and map the information space on online social media by identifying non-trivial proxies for the early detection of massive informational cascades. Furthermore, by combining users traces, we are finally able to draft the main concepts and beliefs of the core narrative of an echo chamber and its related perceptions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=information%20spreading" title="information spreading">information spreading</a>, <a href="https://publications.waset.org/abstracts/search?q=misinformation" title=" misinformation"> misinformation</a>, <a href="https://publications.waset.org/abstracts/search?q=narratives" title=" narratives"> narratives</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20social%20networks" title=" online social networks"> online social networks</a>, <a href="https://publications.waset.org/abstracts/search?q=polarization" title=" polarization"> polarization</a> </p> <a href="https://publications.waset.org/abstracts/68775/polarization-as-a-proxy-of-misinformation-spreading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68775.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">291</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> Developing a Performance Measurement System for Arts-Based Initiatives: Action Research on Italian Corporate Museums</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eleonora%20Carloni">Eleonora Carloni</a>, <a href="https://publications.waset.org/abstracts/search?q=Michela%20Arnaboldi"> Michela Arnaboldi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In academia, the investigation of the relationship between cultural heritage and corporations is ubiquitous in several fields of studies. In practice corporations are more and more integrating arts and cultural heritage in their strategies for disparate benefits, such as: to foster customer’s purchase intention with authentic and aesthetic experiences, to improve their reputation towards local communities, and to motivate employees with creative thinking. There are diverse forms under which corporations set these artistic interventions, from sponsorships to arts-based training centers for employees, but scholars agree that the maximum expression of this cultural trend are corporate museums, growing in number and relevance. Corporate museums are museum-like settings, hosting artworks of corporations’ history and interests. In academia they have been ascribed as strategic asset and they have been associated with diverse uses for corporations’ benefits, from place for preservation of cultural heritage, to tools for public relations and cultural flagship stores. Previous studies have thus extensively but fragmentally studied the diverse benefits of corporate museum opening to corporations, with a lack of comprehensive approach and a digression on how to evaluate and report corporate museum’s performances. Stepping forward, the present study aims to investigate: 1) what are the key performance measures corporate museums need to report to the associated corporations; 2) how are the key performance measures reported to the concerned corporations. This direction of study is not only suggested as future direction in academia but it has solid basis in practice, aiming to answer to the need of corporate museums’ directors to account for corporate museum’s activities to the concerned corporation. Coherently, at an empirical level the study relies on action research method, whose distinctive feature is to develop practical knowledge through a participatory process. This paper indeed relies on the experience of a collaborative project between the researchers and a set of corporate museums in Italy, aimed at co-developing a performance measurement system. The project involved two steps: a first step, in which researchers derived the potential performance measures from literature along with exploratory interviews; a second step, in which researchers supported the pool of corporate museums’ directors in co-developing a set of key performance indicators for reporting. Preliminary empirical findings show that while scholars insist on corporate museums’ capability to develop networking relations, directors insist on the role of museums as internal supplier of knowledge for innovation goals. Moreover, directors stress museums’ cultural mission and outcomes as potential benefits for corporation, by remarking to include both cultural and business measures in the final tool. In addition, they give relevant attention to the wording used in humanistic terms while struggling to express all measures in economic terms. The paper aims to contribute to corporate museums’ and more broadly to arts-based initiatives’ literature in two directions. Firstly, it elaborates key performance measures with related indicators to report on cultural initiatives for corporations. Secondly, it provides evidence of challenges and practices to handle reporting on these initiatives, because of tensions arising from the co-existence of diverse perspectives, namely arts and business worlds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arts-based%20initiative" title="arts-based initiative">arts-based initiative</a>, <a href="https://publications.waset.org/abstracts/search?q=corporate%20museum" title=" corporate museum"> corporate museum</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20organization" title=" hybrid organization"> hybrid organization</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20measurement" title=" performance measurement"> performance measurement</a> </p> <a href="https://publications.waset.org/abstracts/136163/developing-a-performance-measurement-system-for-arts-based-initiatives-action-research-on-italian-corporate-museums" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136163.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">176</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">2</span> Metal-Organic Frameworks-Based Materials for Volatile Organic Compounds Sensing Applications: Strategies to Improve Sensing Performances</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Claudio%20Clemente">Claudio Clemente</a>, <a href="https://publications.waset.org/abstracts/search?q=Valentina%20Gargiulo"> Valentina Gargiulo</a>, <a href="https://publications.waset.org/abstracts/search?q=Alessio%20Occhicone"> Alessio Occhicone</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Piero%20Pepe"> Giovanni Piero Pepe</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Ausanio"> Giovanni Ausanio</a>, <a href="https://publications.waset.org/abstracts/search?q=Michela%20Alf%C3%A8"> Michela Alfè</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Volatile organic compound (VOC) emissions represent a serious risk to human health and the integrity of the ecosystems, especially at high concentrations. For this reason, it is very important to continuously monitor environmental quality and develop fast and reliable portable sensors to allow analysis on site. Chemiresistors have become promising candidates for VOC sensing as their ease of fabrication, variety of suitable sensitive materials, and simple sensing data. A chemoresistive gas sensor is a transducer that allows to measure the concentration of an analyte in the gas phase because the changes in resistance are proportional to the amount of the analyte present. The selection of the sensitive material, which interacts with the target analyte, is very important for the sensor performance. The most used VOC detection materials are metal oxides (MOx) for their rapid recovery, high sensitivity to various gas molecules, easy fabrication. Their sensing performance can be improved in terms of operating temperature, selectivity, and detection limit. Metal-organic frameworks (MOFs) have attracted a lot of attention also in the field of gas sensing due to their high porosity, high surface area, tunable morphologies, structural variety. MOFs are generated by the self-assembly of multidentate organic ligands connecting with adjacent multivalent metal nodes via strong coordination interactions, producing stable and highly ordered crystalline porous materials with well-designed structures. However, most MOFs intrinsically exhibit low electrical conductivity. To improve this property, MOFs can be combined with organic and inorganic materials in a hybrid fashion to produce composite materials or can be transformed into more stable structures. MOFs, indeed, can be employed as the precursors of metal oxides with well-designed architectures via the calcination method. The MOF-derived MOx partially preserved the original structure with high surface area and intrinsic open pores, which act as trapping centers for gas molecules, and showed a higher electrical conductivity. Core-shell heterostructures, in which the surface of a metal oxide core is completely coated by a MOF shell, forming a junction at the core-shell heterointerface, can also be synthesized. Also, nanocomposite in which MOF structures are intercalated with graphene related materials can also be produced, and the conductivity increases thanks to the high mobility of electrons of carbon materials. As MOF structures, zinc-based MOFs belonging to the ZIF family were selected in this work. Several Zn-based materials based and/or derived from MOFs were produced, structurally characterized, and arranged in a chemo resistive architecture, also exploring the potentiality of different approaches of sensing layer deposition based on PLD (pulsed laser deposition) and, in case of thermally labile materials, MAPLE (Matrix Assisted Pulsed Laser Evaporation) to enhance the adhesion to the support. The sensors were tested in a controlled humidity chamber, allowing for the possibility of varying the concentration of ethanol, a typical analyte chosen among the VOCs for a first survey. The effect of heating the chemiresistor to improve sensing performances was also explored. Future research will focus on exploring new manufacturing processes for MOF-based gas sensors with the aim to improve sensitivity, selectivity and reduce operating temperatures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemiresistors" title="chemiresistors">chemiresistors</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20sensors" title=" gas sensors"> gas sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene%20related%20materials" title=" graphene related materials"> graphene related materials</a>, <a href="https://publications.waset.org/abstracts/search?q=laser%20deposition" title=" laser deposition"> laser deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=MAPLE" title=" MAPLE"> MAPLE</a>, <a href="https://publications.waset.org/abstracts/search?q=metal-organic%20frameworks" title=" metal-organic frameworks"> metal-organic frameworks</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20oxides" title=" metal oxides"> metal oxides</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposites" title=" nanocomposites"> nanocomposites</a>, <a href="https://publications.waset.org/abstracts/search?q=sensing%20performance" title=" sensing performance"> sensing performance</a>, <a href="https://publications.waset.org/abstracts/search?q=transduction%20mechanism" title=" transduction mechanism"> transduction mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=volatile%20organic%20compounds" title=" volatile organic compounds"> volatile organic compounds</a> </p> <a href="https://publications.waset.org/abstracts/184645/metal-organic-frameworks-based-materials-for-volatile-organic-compounds-sensing-applications-strategies-to-improve-sensing-performances" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184645.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">64</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> Industrial Waste to Energy Technology: Engineering Biowaste as High Potential Anode Electrode for Application in Lithium-Ion Batteries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pejman%20Salimi">Pejman Salimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastiano%20Tieuli"> Sebastiano Tieuli</a>, <a href="https://publications.waset.org/abstracts/search?q=Somayeh%20Taghavi"> Somayeh Taghavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Michela%20Signoretto"> Michela Signoretto</a>, <a href="https://publications.waset.org/abstracts/search?q=Remo%20Proietti%20Zaccaria"> Remo Proietti Zaccaria</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Increasing the growth of industrial waste due to the large quantities of production leads to numerous environmental and economic challenges, such as climate change, soil and water contamination, human disease, etc. Energy recovery of waste can be applied to produce heat or electricity. This strategy allows for the reduction of energy produced using coal or other fuels and directly reduces greenhouse gas emissions. Among different factories, leather manufacturing plays a very important role in the whole world from the socio-economic point of view. The leather industry plays a very important role in our society from a socio-economic point of view. Even though the leather industry uses a by-product from the meat industry as raw material, it is considered as an activity demanding integrated prevention and control of pollution. Along the entire process from raw skins/hides to finished leather, a huge amount of solid and water waste is generated. Solid wastes include fleshings, raw trimmings, shavings, buffing dust, etc. One of the most abundant solid wastes generated throughout leather tanning is shaving waste. Leather shaving is a mechanical process that aims at reducing the tanned skin to a specific thickness before tanning and finishing. This product consists mainly of collagen and tanning agent. At present, most of the world's leather processing is chrome-tanned based. Consequently, large amounts of chromium-containing shaving wastes need to be treated. The major concern about the management of this kind of solid waste is ascribed to chrome content, which makes the conventional disposal methods, such as landfilling and incineration, not practicable. Therefore, many efforts have been developed in recent decades to promote eco-friendly/alternative leather production and more effective waste management. Herein, shaving waste resulting from metal-free tanning technology is proposed as low-cost precursors for the preparation of carbon material as anodes for lithium-ion batteries (LIBs). In line with the philosophy of a reduced environmental impact, for preparing fully sustainable and environmentally friendly LIBs anodes, deionized water and carboxymethyl cellulose (CMC) have been used as alternatives to toxic/teratogen N-methyl-2- pyrrolidone (NMP) and to biologically hazardous Polyvinylidene fluoride (PVdF), respectively. Furthermore, going towards the reduced cost, we employed water solvent and fluoride-free bio-derived CMC binder (as an alternative to NMP and PVdF, respectively) together with LiFePO₄ (LFP) when a full cell was considered. These actions make closer to the 2030 goal of having green LIBs at 100 $ kW h⁻¹. Besides, the preparation of the water-based electrodes does not need a controlled environment and due to the higher vapour pressure of water in comparison with NMP, the water-based electrode drying is much faster. This aspect determines an important consequence, namely a reduced energy consumption for the electrode preparation. The electrode derived from leather waste demonstrated a discharge capacity of 735 mAh g⁻¹ after 1000 charge and discharge cycles at 0.5 A g⁻¹. This promising performance is ascribed to the synergistic effect of defects, interlayer spacing, heteroatoms-doped (N, O, and S), high specific surface area, and hierarchical micro/mesopore structure of the biochar. Interestingly, these features of activated biochars derived from the leather industry open the way for possible applications in other EESDs as well. <p class="card-text"><strong>Keywords:</strong> <a
