The painter had to adapt to various political and social ruptures: from royalty to the French Revolution, from the empire of Napoleon Bonaparte to the empire of King John VI. According to the method of analysis that involves the idea of "political iconography" from Carlo Ginzburg and the concept of "representation" associated with Georges Didi-Huberman, this work wishes to insert Taunay in its context through the analysis of his portrait made by a colleague of the profession and of a Brazilian landscape painted of his own (1816-1821) and, in which he represented himself. Finally, the intention is to find in these two paintings how Nicolas-Antoine Taunay faced himself and in the middle that surrounded him in the traffic that was forced to make it between Paris and Rio de Janeiro. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicolas-Antoine%20Taunay" title="Nicolas-Antoine Taunay">Nicolas-Antoine Taunay</a>, <a href="https://publications.waset.org/abstracts/search?q=politic%20iconography" title=" politic iconography"> politic iconography</a>, <a href="https://publications.waset.org/abstracts/search?q=French%20art" title=" French art"> French art</a>, <a href="https://publications.waset.org/abstracts/search?q=Brazilian%20art" title=" Brazilian art"> Brazilian art</a>, <a href="https://publications.waset.org/abstracts/search?q=19th%20century" title=" 19th century"> 19th century</a> </p> <a href="https://publications.waset.org/abstracts/149733/polytic-iconography-the-sky-and-pants-of-nicolas-antoine-taunay-1755-1830" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149733.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">94</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Argos-Linked Fastloc GPS Reveals the Resting Activity of Migrating Sea Turtles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gail%20Schofield">Gail Schofield</a>, <a href="https://publications.waset.org/abstracts/search?q=Antoine%20M.%20Dujon"> Antoine M.

Hays</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Variation in diel movement patterns during migration provides information on the strategies used by animals to maximize energy efficiency and ensure the successful completion of migration. For instance, many flying and land-based terrestrial species stop to rest and refuel at regular intervals along the migratory route, or at transitory ‘stopover’ sites, depending on resource availability. However, in cases where stopping is not possible (such as over–or through deep–open oceans, or over deserts and mountains), non-stop travel is required, with animals needing to develop strategies to rest while actively traveling. Recent advances in biologging technologies have identified mid-flight micro sleeps by swifts in Africa during the 10-month non-breeding period, and the use of lateralized sleep behavior in orca and bottlenose dolphins during migration. Here, highly accurate locations obtained by Argos-linked Fastloc-GPS transmitters of adult green (n=8 turtles, 9487 locations) and loggerhead (n=46 turtles, 47,588 locations) sea turtles migrating around thousand kilometers (over several weeks) from breeding to foraging grounds across the Indian and Mediterranean oceans were used to identify potential resting strategies. Stopovers were only documented for seven turtles, lasting up to 6 days; thus, this strategy was not commonly used, possibly due to the lack of potential ‘shallow’ ( < 100 m seabed depth) sites along routes. However, observations of the day versus night speed of travel indicated that turtles might use other mechanisms to rest. For instance, turtles traveled an average 31% slower at night compared to day during oceanic crossings. Slower travel speeds at night might be explained by turtles swimming in a less direct line at night and/or deeper dives reducing their forward motion, as indicated through studies using Argos-linked transmitters and accelerometers. Furthermore, within the first 24 h of entering waters shallower than 100 m towards the end of migration (the depth at which sea turtles can swim and rest on the seabed), some individuals travelled 72% slower at night, repeating this behavior intermittently (each time for a one-night duration at 3–6-day intervals) until reaching the foraging grounds. If the turtles were, in fact, resting on the seabed at this point, they could be inactive for up to 8-hours, facilitating protracted periods of rest after several weeks of constant swimming. Turtles might not rest every night once within these shallower depths, due to the time constraints of reaching foraging grounds and restoring depleted energetic reserves (as sea turtles are capital breeders, they tend not to feed for several months during migration to and from the breeding grounds and while breeding). In conclusion, access to data-rich, highly accurate Argos-linked Fastloc-GPS provided information about differences in the day versus night activity at different stages of migration, allowing us, for the first time, to compare the strategies used by a marine vertebrate with terrestrial land-based and flying species. However, the question of what resting strategies are used by individuals that remain in oceanic waters to forage, with combinations of highly accurate Argos-linked Fastloc-GPS transmitters and accelerometry or time-depth recorders being required for sufficient numbers of individuals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=argos-linked%20fastloc%20GPS" title="argos-linked fastloc GPS">argos-linked fastloc GPS</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20loggers" title=" data loggers"> data loggers</a>, <a href="https://publications.waset.org/abstracts/search?q=migration" title=" migration"> migration</a>, <a href="https://publications.waset.org/abstracts/search?q=resting%20strategy" title=" resting strategy"> resting strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=telemetry" title=" telemetry"> telemetry</a> </p> <a href="https://publications.waset.org/abstracts/90572/argos-linked-fastloc-gps-reveals-the-resting-activity-of-migrating-sea-turtles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90572.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">40</span> Data Presentation of Lane-Changing Events Trajectories Using HighD Dataset</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Basma%20Khelfa">Basma Khelfa</a>, <a href="https://publications.waset.org/abstracts/search?q=Antoine%20Tordeux"> Antoine Tordeux</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibrahima%20Ba"> Ibrahima Ba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present a descriptive analysis data of lane-changing events in multi-lane roads.

Concerning 3D-CRT treatment planning, the MUVC can be performed manually applying the standard ESTRO formalism. However, due to the complex shape and the amount of beams in advanced treatment planning technic such as RapidArc, the manual independent MUVC is inadequate. Therefore, commercially available software such as RadCalc can be used to perform the MUVC in complex treatment planning been. Indeed, RadCalc (version 6.3 LifeLine Inc.) uses a simplified Clarkson algorithm to compute the dose contribution for individual RapidArc fields to the isocenter. The purpose of this project is the validation of RadCalc in 3D-CRT and RapidArc for treatment planning dosimetry quality assurance at Antoine Lacassagne center (Nice, France). Firstly, the interfaces between RadCalc and our treatment planning systems (TPS) Isogray (version 4.2) and Eclipse (version13.6) were checked for data transfer accuracy. Secondly, we created test plans in both Isogray and Eclipse featuring open fields, wedges fields, and irregular MLC fields. These test plans were transferred from TPSs according to the radiotherapy protocol of DICOM RT to RadCalc and the linac via Mosaiq (version 2.5). Measurements were performed in water phantom using a PTW cylindrical semiflex ionisation chamber (0.3 cm³, 31010) and compared with the TPSs and RadCalc calculation. Finally, 30 3D-CRT plans and 40 RapidArc plans created with patients CT scan were recalculated using the CT scan of a solid PMMA water equivalent phantom for 3D-CRT and the Octavius II phantom (PTW) CT scan for RapidArc. Next, we measure the doses delivered into these phantoms for each plan with a 0.3 cm³ PTW 31010 cylindrical semiflex ionisation chamber (3D-CRT) and 0.015 cm³ PTW PinPoint ionisation chamber (Rapidarc). For our test plans, good agreements were found between calculation (RadCalc and TPSs) and measurement (mean: 1.3%; standard deviation: ± 0.8%). Regarding the patient plans, the measured doses were compared to the calculation in RadCalc and in our TPSs. Moreover, RadCalc calculations were compared to Isogray and Eclispse ones. Agreements better than (2.8%; ± 1.2%) were found between RadCalc and TPSs. As for the comparison between calculation and measurement the agreement for all of our plans was better than (2.3%; ± 1.1%). The independent MU verification calculation software RadCal has been validated for clinical use and for both 3D-CRT and RapidArc techniques. The perspective of this project includes the validation of RadCal for the Tomotherapy machine installed at centre Antoine Lacassagne. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20conformational%20radiotherapy" title="3D conformational radiotherapy">3D conformational radiotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=intensity%20modulated%20radiotherapy" title=" intensity modulated radiotherapy"> intensity modulated radiotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=monitor%20unit%20calculation" title=" monitor unit calculation"> monitor unit calculation</a>, <a href="https://publications.waset.org/abstracts/search?q=dosimetry%20quality%20assurance" title=" dosimetry quality assurance"> dosimetry quality assurance</a> </p> <a href="https://publications.waset.org/abstracts/78071/the-validation-of-radcalc-for-clinical-use-an-independent-monitor-unit-verification-software" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78071.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">216</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> Energy-Level Structure of a Confined Electron-Positron Pair in Nanostructure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tokuei%20Sako">Tokuei Sako</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul-Antoine%20Hervieux"> Paul-Antoine Hervieux</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The energy-level structure of a pair of electron and positron confined in a quasi-one-dimensional nano-scale potential well has been investigated focusing on its trend in the small limit of confinement strength ω, namely, the Wigner molecular regime.

The resultant energy spectrum shows a band structure characterized by ω for the large ω regime whereas for the small ω regime it shows an energy-level pattern dominated by excitation into the in-phase motion of the two particles.

Specifically, using the World Bank’s 2014 and 2011 Global Financial Inclusion (Global Findex) databases, we apply special regressor approach. We find that the deposit insurance program increases significantly, everything else equal, the probability that people save their money at a financial institution by 11 percentage points in Gabon, by 22.2 percentage points in DR Congo and by 15.1 percentage points in Chad. These effects are matched with positive effects of age and education level. But in Cameroon, the effect of deposit insurance is not significant. The policies aimed at fostering financial inclusion will be more effective if there is a deposit insurance scheme in place, along with awareness among young people, and education programs.

When applied on synthetic images, the proposed approach provides good performance, segmentations obtained are accurate, their shape is consistent with the ground truth, and the extracted information is reliable. The results obtained on MR images confirm such observations. Our approach allows, even for difficult cases of MR images, to extract a segmentation with good performance in terms of accuracy and shape, which implies that the geometry of the tumor is preserved for further clinical activities (such as automatic extraction of pharmaco-kinetics properties, lesion characterization, etc). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=defuzzification" title="defuzzification">defuzzification</a>, <a href="https://publications.waset.org/abstracts/search?q=floating%20search" title=" floating search"> floating search</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20clustering" title=" fuzzy clustering"> fuzzy clustering</a>, <a href="https://publications.waset.org/abstracts/search?q=Zernike%20moments" title=" Zernike moments "> Zernike moments </a> </p> <a href="https://publications.waset.org/abstracts/32509/a-fuzzy-approach-to-liver-tumor-segmentation-with-zernike-moments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32509.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">452</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> Cash Flow Optimization on Synthetic CDOs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Timoth%C3%A9e%20Bligny">Timothée Bligny</a>, <a href="https://publications.waset.org/abstracts/search?q=Cl%C3%A9ment%20Codron"> Clément Codron</a>, <a href="https://publications.waset.org/abstracts/search?q=Antoine%20Estruch"> Antoine Estruch</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Girodet"> Nicolas Girodet</a>, <a href="https://publications.waset.org/abstracts/search?q=Cl%C3%A9ment%20Ginet"> Clément Ginet</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Collateralized Debt Obligations are not as widely used nowadays as they were before 2007 Subprime crisis. Nonetheless there remains an enthralling challenge to optimize cash flows associated with synthetic CDOs. A Gaussian-based model is used here in which default correlation and unconditional probabilities of default are highlighted. Then numerous simulations are performed based on this model for different scenarios in order to evaluate the associated cash flows given a specific number of defaults at different periods of time. Cash flows are not solely calculated on a single bought or sold tranche but rather on a combination of bought and sold tranches. With some assumptions, the simplex algorithm gives a way to find the maximum cash flow according to correlation of defaults and maturities. The used Gaussian model is not realistic in crisis situations. Besides present system does not handle buying or selling a portion of a tranche but only the whole tranche. However the work provides the investor with relevant elements on how to know what and when to buy and sell. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=synthetic%20collateralized%20debt%20obligation%20%28CDO%29" title="synthetic collateralized debt obligation (CDO)">synthetic collateralized debt obligation (CDO)</a>, <a href="https://publications.waset.org/abstracts/search?q=credit%20default%20swap%20%28CDS%29" title=" credit default swap (CDS)"> credit default swap (CDS)</a>, <a href="https://publications.waset.org/abstracts/search?q=cash%20flow%20optimization" title=" cash flow optimization"> cash flow optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=probability%20of%20default" title=" probability of default"> probability of default</a>, <a href="https://publications.waset.org/abstracts/search?q=default%20correlation" title=" default correlation"> default correlation</a>, <a href="https://publications.waset.org/abstracts/search?q=strategies" title=" strategies"> strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=simplex" title=" simplex "> simplex </a> </p> <a href="https://publications.waset.org/abstracts/10900/cash-flow-optimization-on-synthetic-cdos" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10900.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">274</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> Evaluation of the Impact of Scraping Operations during Winter Road Maintenance on Pavement Skid Resistance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Garance%20Liaboeuf">Garance Liaboeuf</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Bouteldja"> Mohamed Bouteldja</a>, <a href="https://publications.waset.org/abstracts/search?q=Antoine%20Martinet"> Antoine Martinet</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Grignard"> Nicolas Grignard</a>, <a href="https://publications.waset.org/abstracts/search?q=Damien%20Pilet"> Damien Pilet</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Daouadji"> Ali Daouadji</a>, <a href="https://publications.waset.org/abstracts/search?q=Alain%20Le%20Bot"> Alain Le Bot</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A series of in-situ tests is set up to evaluate and quantify the long-term effects of scraping operations using steel plows on the skid resistance of pavements. Three pavements are tested, and a total number of 1.800 snowplow scrapings are applied. The skid resistance of the pavements is measured periodically using two indicators on two scales: an average profile depth (macrotexture) and a longitudinal friction coefficient (microtexture). The results of these tests show a reduction in the average profile depth between 4 % and 10 %, depending on the asphalt composition. This reduction of macrotexture is correlated with the reduction of high points on surfaces due to the removal of portions of the aggregate surfaces. The longitudinal friction coefficient of pavements decreases by 4% to 10%. This reduction in microtexture is related to the polishing of the surface of the aggregate used in the pavements. These variations of skid resistance are not linear. A phenomenon of regeneration of the friction coefficient is observed for pavements composed of sand-lime aggregates after several scraping operations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GripTester" title="GripTester">GripTester</a>, <a href="https://publications.waset.org/abstracts/search?q=macrotexture" title=" macrotexture"> macrotexture</a>, <a href="https://publications.waset.org/abstracts/search?q=microtexture" title=" microtexture"> microtexture</a>, <a href="https://publications.waset.org/abstracts/search?q=pavement" title=" pavement"> pavement</a>, <a href="https://publications.waset.org/abstracts/search?q=skid%20resistance" title=" skid resistance"> skid resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=snowplow" title=" snowplow"> snowplow</a>, <a href="https://publications.waset.org/abstracts/search?q=TM2" title=" TM2"> TM2</a>, <a href="https://publications.waset.org/abstracts/search?q=winter%20road%20maintenance" title=" winter road maintenance"> winter road maintenance</a> </p> <a href="https://publications.waset.org/abstracts/183005/evaluation-of-the-impact-of-scraping-operations-during-winter-road-maintenance-on-pavement-skid-resistance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183005.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">32</span> Effects of Voltage Pulse Characteristics on Some Performance Parameters of LiₓCoO₂-based Resistive Switching Memory Devices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Van%20Son%20Nguyen">Van Son Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Van%20Huy%20Mai"> Van Huy Mai</a>, <a href="https://publications.waset.org/abstracts/search?q=Alec%20Moradpour"> Alec Moradpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Pascale%20Auban%20Senzier"> Pascale Auban Senzier</a>, <a href="https://publications.waset.org/abstracts/search?q=Claude%20Pasquier"> Claude Pasquier</a>, <a href="https://publications.waset.org/abstracts/search?q=Kang%20Wang"> Kang Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Pierre-Antoine%20Albouy"> Pierre-Antoine Albouy</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20J.%20Rozenberg"> Marcelo J.

Among remediation methods, soil washing is an effective, relatively fast, and widely used process. This study assesses its coupling with ultrasound: indeed, sonication induces the formation of cavitation bubbles in solution that enhance local mass transfer through agitation and particle erosion. The removal of target toxic elements Ni(II) and Zn(II) from vermiculite clay has been studied under 20 kHz ultrasound and silent conditions. Several acids were tested, and HCl was chosen as the solvent. The effects of solid/liquid ratio and particle size were investigated. Metal repartition in the clay has been followed by Tessier's sequential extraction procedure. The results showed that more metal elements bound to the challenging residual phase were desorbed with 20 kHz ultrasound than in silent conditions. This supports the promising application of ultrasound for heavy metal desorption in difficult conditions. Further experiments were performed at high-frequency US (362 kHz), and it was shown that fragmentation of the vermiculite particles is then limited, while positive effects of US in the decontamination are kept. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=desorption" title="desorption">desorption</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a>, <a href="https://publications.waset.org/abstracts/search?q=vermiculite" title=" vermiculite"> vermiculite</a> </p> <a href="https://publications.waset.org/abstracts/147404/ultrasound-assisted-soil-washing-process-for-the-removal-of-heavy-metals-from-clays" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147404.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">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> The Effect of Mood and Normative Conformity on Prosocial Behavior</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antoine%20Miguel%20Borromeo">Antoine Miguel Borromeo</a>, <a href="https://publications.waset.org/abstracts/search?q=Kristian%20Anthony%20Menez"> Kristian Anthony Menez</a>, <a href="https://publications.waset.org/abstracts/search?q=Moira%20Louise%20Ordonez"> Moira Louise Ordonez</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Carl%20Rabaya"> David Carl Rabaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed to test if induced mood and normative conformity have any effect specifically on prosocial behavior, which was operationalized as the willingness to donate to a non-government organization. The effect of current attitude towards the object of the prosocial behavior was also considered with a covariate test. Undergraduates taking an introductory course on psychology (N = 132) from the University of the Philippines Diliman were asked how much money they were willing to donate after being presented a video about coral reef destruction and a website that advocates towards saving the coral reefs. A 3 (Induced mood: Positive vs Fear and Sadness vs Anger, Contempt, and Disgust) x 2 (Normative conformity: Presence vs Absence) between-subjects analysis of covariance was used for experimentation. Prosocial behavior was measured by presenting a circumstance wherein participants were given money and asked if they were willing to donate an amount to the non-government organization. An analysis of covariance revealed that the mood induced has no significant effect on prosocial behavior, F(2,125) = 0.654, p > 0.05. The analysis also showed how normative conformity has no significant effect on prosocial behavior, F(1,125) = 0.238, p > 0.05, as well as their interaction F(2, 125) = 1.580, p > 0.05. However, the covariate, current attitude towards corals was revealed to be significant, F(1,125) = 8.778, p < 0.05.

The healthcare providers’ ability to effectively communicate in such situations represents a vital lifeline for parents. In this context, communication becomes a crucial element not only for getting through the period of grief but also for the future. We mobilized the five stages of grief model to summarize existing literature regarding the ways in which the experience ofan autism spectrum disorder diagnosis disclosurealigns with the experience of grief to explore how this can inform best practices for effective communication with parents through the diagnosis disclosure. Fifteen publications met inclusion criteria. Findings from the scoping review of empirical studies show that parents/families experience grief-like emotions during the diagnosis disclosure. However, grief is not an outcome of the encounter itself. In fact, the experience of the encounter can help mitigate the grief experience. The way parents/families receive and react to the ‘news’ depends on their preparedness, knowledge, and the support received through the experience. Individual communication skills, as well as policies and regulations, should be examined to alleviate adverse reactions in this context. These findings highlight the importance of further research into effective parent-provider communication strategies and their place in supporting quality autism care. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autism%20spectrum%20disorder" title="autism spectrum disorder">autism spectrum disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=autism%20spectrum%20disorder%20diagnosis" title=" autism spectrum disorder diagnosis"> autism spectrum disorder diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnosis%20disclosure" title=" diagnosis disclosure"> diagnosis disclosure</a>, <a href="https://publications.waset.org/abstracts/search?q=parent-provider%20communication" title=" parent-provider communication"> parent-provider communication</a>, <a href="https://publications.waset.org/abstracts/search?q=parental%20grief" title=" parental grief"> parental grief</a> </p> <a href="https://publications.waset.org/abstracts/144621/opportunities-for-effective-communication-through-the-delivery-of-an-autism-spectrum-disorder-diagnosis-a-scoping-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144621.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">175</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> Prevalence and Associated Factors with Burnout Among Secondary School Teachers in the City of Cotonou in Benin in 2022</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antoine%20Vikkey%20Hinson">Antoine Vikkey Hinson</a>, <a href="https://publications.waset.org/abstracts/search?q=Ranty%20Jolianelle%20Dassi"> Ranty Jolianelle Dassi</a>, <a href="https://publications.waset.org/abstracts/search?q=Menonli%20Adjobimey"> Menonli Adjobimey</a>, <a href="https://publications.waset.org/abstracts/search?q=Rose%20Mikponhoue"> Rose Mikponhoue</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Ayelo"> Paul Ayelo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The psychological hardship of the teaching profession maintains a chronic stress that inevitably evolves into burnout (BO) in the absence of adequate preventive measures. The objective of this study is to study the prevalence and factors associated with burnout among secondary school teachers in the city of Cotonou in 2022. Methods: This was a descriptive cross-sectional study with an analytical aim and prospective data collection that took place over a period of 2 months, from July 19 to August 19 and from October 1 to October 31, 2022. Sampling was done using a three-stage probability sampling technique. Data analysis was performed using R 4.1.1 software. Bivariate logistic regression was used to identify associated factors. The significance level chosen was 5% (p < 0.05). Results: A total of 270 teachers were included in the study, of whom 208 (77.00%) were men. The mean age of the workers was 38.03 ± 8.30 years. According to the Maslach Burnout Inventory, 58.51% of the teachers had burnout, with 41.10% of teachers in emotional exhaustion, 27.40% in depersonalization and 21.90% in loss of personal accomplishment. The severity of the syndrome was low to moderate in almost all teachers. The occurrence of BO was associated with), not practicing sports (ORa= 2,38 [1,32; 4,28]), jobs training (ORa= 1,86 [1,04; 3,34]) and an imbalance of effort/reward (ORa= 5,98 [2,24;15,98]). Conclusion: The prevalence of BO is high among secondary school teachers in the city of Cotonou. A larger scale study, including research on its consequences on the teacher and the learner, is necessary in order to act quickly to implement a prevention program. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=burnout" title="burnout">burnout</a>, <a href="https://publications.waset.org/abstracts/search?q=teachers" title=" teachers"> teachers</a>, <a href="https://publications.waset.org/abstracts/search?q=Maslach%20burnout%20inventory" title=" Maslach burnout inventory"> Maslach burnout inventory</a>, <a href="https://publications.waset.org/abstracts/search?q=associated%20factors" title=" associated factors"> associated factors</a>, <a href="https://publications.waset.org/abstracts/search?q=Benin" title=" Benin"> Benin</a> </p> <a href="https://publications.waset.org/abstracts/183372/prevalence-and-associated-factors-with-burnout-among-secondary-school-teachers-in-the-city-of-cotonou-in-benin-in-2022" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183372.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">76</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Concentrations of Some Metallic Trace Elements in Twelve Sludge Incineration Ashes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lotfi%20Khiari">Lotfi Khiari</a>, <a href="https://publications.waset.org/abstracts/search?q=Antoine%20Karam"> Antoine Karam</a>, <a href="https://publications.waset.org/abstracts/search?q=Claude-Alla%20Joseph"> Claude-Alla Joseph</a>, <a href="https://publications.waset.org/abstracts/search?q=Marc%20H%C3%A9bert"> Marc Hébert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of incineration of sludge generated from municipal or agri-food waste treatment plant is to reduce the volume of sludge to be disposed of as a solid or liquid waste, whilst concentrating or destroying potentially harmful volatile substances. In some cities in Canada and United States of America (USA), a large amount of sludge is incinerated, which entails a loss of organic matter and water leading to phosphorus, potassium and some metallic trace element (MTE) accumulation in ashes. The purpose of this study was to evaluate the concentration of potentially hazardous MTE such as cadmium (Cd), lead (Pb) and mercury (Hg) in twelve sludge incineration ash samples obtained from municipal wastewater and other food processing waste treatments from Canada and USA. The average, maximum, and minimum values of MTE in ashes were calculated for each city individually and all together. The trace metal concentration values were compared to the literature reported values. The concentrations of MTE in ashes vary widely depending on the sludge origins and treatment options. The concentrations of MTE in ashes were found the range of 0.1-6.4 mg/kg for Cd; 13-286 mg/kg for Pb and 0.1-0.5 mg/kg for Hg. On average, the following order of metal concentration in ashes was observed: Pb > Cd > Hg. Results show that metal contents in most ashes were similar to MTE levels in synthetic inorganic fertilizers and many fertilizing residual materials. Consequently, the environmental effects of MTE content of these ashes would be low. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biosolids" title="biosolids">biosolids</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling" title=" recycling"> recycling</a>, <a href="https://publications.waset.org/abstracts/search?q=sewage%20sludge" title=" sewage sludge"> sewage sludge</a> </p> <a href="https://publications.waset.org/abstracts/37772/concentrations-of-some-metallic-trace-elements-in-twelve-sludge-incineration-ashes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37772.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">380</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Effectiveness of Weather Index Insurance for Smallholders in Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Federica%20Di%20Marcantonio">Federica Di Marcantonio</a>, <a href="https://publications.waset.org/abstracts/search?q=Antoine%20Leblois"> Antoine Leblois</a>, <a href="https://publications.waset.org/abstracts/search?q=Wolfgang%20G%C3%B6bel"> Wolfgang Göbel</a>, <a href="https://publications.waset.org/abstracts/search?q=Herv%C3%A8%20Kerdiles"> Hervè Kerdiles</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Weather-related shocks can threaten the ability of farmers to maintain their agricultural output and food security levels. Informal coping mechanisms (i.e. migration or community risk sharing) have always played a significant role in mitigating the negative effects of weather-related shocks in Ethiopia, but they have been found to be an incomplete strategy, particularly as a response to covariate shocks. Particularly, as an alternative to the traditional risk pooling products, an innovative form of insurance known as Index-based Insurance has received a lot of attention from researchers and international organizations, leading to an increased number of pilot initiatives in many countries. Despite the potential benefit of the product in protecting the livelihoods of farmers and pastoralists against climate shocks, to date there has been an unexpectedly low uptake. Using information from current pilot projects on index-based insurance in Ethiopia, this paper discusses the determinants of uptake that have so far undermined the scaling-up of the products, by focusing in particular on weather data availability, price affordability and willingness to pay. We found that, aside from data constraint issues, high price elasticity and low willingness to pay represent impediments to the development of the market. These results, bring us to rethink the role of index insurance as products for enhancing smallholders’ response to covariate shocks, and particularly for improving their food security. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=index-based%20insurance" title="index-based insurance">index-based insurance</a>, <a href="https://publications.waset.org/abstracts/search?q=willingness%20to%20pay" title=" willingness to pay"> willingness to pay</a>, <a href="https://publications.waset.org/abstracts/search?q=satellite%20information" title=" satellite information"> satellite information</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a> </p> <a href="https://publications.waset.org/abstracts/40493/effectiveness-of-weather-index-insurance-for-smallholders-in-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40493.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">405</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> Performing Diagnosis in Building with Partially Valid Heterogeneous Tests</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Houda%20Najeh">Houda Najeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahendra%20Pratap%20Singh"> Mahendra Pratap Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=St%C3%A9phane%20Ploix"> Stéphane Ploix</a>, <a href="https://publications.waset.org/abstracts/search?q=Antoine%20Caucheteux"> Antoine Caucheteux</a>, <a href="https://publications.waset.org/abstracts/search?q=Karim%20Chabir"> Karim Chabir</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Naceur%20Abdelkrim"> Mohamed Naceur Abdelkrim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Building system is highly vulnerable to different kinds of faults and human misbehaviors. Energy efficiency and user comfort are directly targeted due to abnormalities in building operation. The available fault diagnosis tools and methodologies particularly rely on rules or pure model-based approaches. It is assumed that model or rule-based test could be applied to any situation without taking into account actual testing contexts. Contextual tests with validity domain could reduce a lot of the design of detection tests. The main objective of this paper is to consider fault validity when validate the test model considering the non-modeled events such as occupancy, weather conditions, door and window openings and the integration of the knowledge of the expert on the state of the system. The concept of heterogeneous tests is combined with test validity to generate fault diagnoses. A combination of rules, range and model-based tests known as heterogeneous tests are proposed to reduce the modeling complexity. Calculation of logical diagnoses coming from artificial intelligence provides a global explanation consistent with the test result. An application example shows the efficiency of the proposed technique: an office setting at Grenoble Institute of Technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heterogeneous%20tests" title="heterogeneous tests">heterogeneous tests</a>, <a href="https://publications.waset.org/abstracts/search?q=validity" title=" validity"> validity</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20system" title=" building system"> building system</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor%20grids" title=" sensor grids"> sensor grids</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor%20fault" title=" sensor fault"> sensor fault</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnosis" title=" diagnosis"> diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=fault%20detection%20and%20isolation" title=" fault detection and isolation"> fault detection and isolation</a> </p> <a href="https://publications.waset.org/abstracts/100728/performing-diagnosis-in-building-with-partially-valid-heterogeneous-tests" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100728.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">294</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> Uncertainty Assessment in Building Energy Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fally%20Titikpina">Fally Titikpina</a>, <a href="https://publications.waset.org/abstracts/search?q=Abderafi%20Charki"> Abderafi Charki</a>, <a href="https://publications.waset.org/abstracts/search?q=Antoine%20Caucheteux"> Antoine Caucheteux</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Bigaud"> David Bigaud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The building sector is one of the largest energy consumer with about 40% of the final energy consumption in the European Union. Ensuring building energy performance is of scientific, technological and sociological matter. To assess a building energy performance, the consumption being predicted or estimated during the design stage is compared with the measured consumption when the building is operational. When valuing this performance, many buildings show significant differences between the calculated and measured consumption. In order to assess the performance accurately and ensure the thermal efficiency of the building, it is necessary to evaluate the uncertainties involved not only in measurement but also those induced by the propagation of dynamic and static input data in the model being used. The evaluation of measurement uncertainty is based on both the knowledge about the measurement process and the input quantities which influence the result of measurement. Measurement uncertainty can be evaluated within the framework of conventional statistics presented in the \textit{Guide to the Expression of Measurement Uncertainty (GUM)} as well as by Bayesian Statistical Theory (BST). Another choice is the use of numerical methods like Monte Carlo Simulation (MCS). In this paper, we proposed to evaluate the uncertainty associated to the use of a simplified model for the estimation of the energy consumption of a given building. A detailed review and discussion of these three approaches (GUM, MCS and BST) is given. Therefore, an office building has been monitored and multiple sensors have been mounted on candidate locations to get required data. The monitored zone is composed of six offices and has an overall surface of 102 $m^2$. Temperature data, electrical and heating consumption, windows opening and occupancy rate are the features for our research work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building%20energy%20performance" title="building energy performance">building energy performance</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertainty%20evaluation" title=" uncertainty evaluation"> uncertainty evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=GUM" title=" GUM"> GUM</a>, <a href="https://publications.waset.org/abstracts/search?q=bayesian%20approach" title=" bayesian approach"> bayesian approach</a>, <a href="https://publications.waset.org/abstracts/search?q=monte%20carlo%20method" title=" monte carlo method"> monte carlo method</a> </p> <a href="https://publications.waset.org/abstracts/25133/uncertainty-assessment-in-building-energy-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25133.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">459</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Prevalence and Factors Associated to Work Accidents in the Construction Sector in Benin: Cases of CFIR – Consulting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antoine%20Vikkey%20Hinson">Antoine Vikkey Hinson</a>, <a href="https://publications.waset.org/abstracts/search?q=Menonli%20Adjobimey"> Menonli Adjobimey</a>, <a href="https://publications.waset.org/abstracts/search?q=Gemayel%20Ahmed%20Biokou"> Gemayel Ahmed Biokou</a>, <a href="https://publications.waset.org/abstracts/search?q=Rose%20Mikponhoue"> Rose Mikponhoue</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Construction industry is a critical concern with regard to Health and Safety Service worldwide. World health Organization revealed that work-related disease and trauma were held responsible for the death of one million nine hundred thousand people in 2016. The aim of this study it was to determine the prevalence and factors associated with the occurrence of work accidents in a construction industry in Benin. Method: It was a descriptive cross-sectional and analytical study. Data analysis was performed with R software 4.1.1. In multivariate analysis, we performed a binary logistic regression. OR adjusted (ORa) association measures and their 95% confidence interval [CI95%] were presented for the explanatory variables used in the final model. The significance threshold for all tests selected was 5% (p < 0.05) Result: In this study, 472 workers were included, and, of these, 452 (95.7%) were men corresponding to a sex ratio of 22.6. The average age of the workers was 33 years ± 8.8 years. Workers were mostly laborers (84.7%), and had declared having inadequate personal protective equipment (50.6%, n=239). The prevalence of work accidents is 50.8%. Collision with a rolling stock (25.8%), cut (16.2%), and stumbling (16.2%) were the main types of work accidents on the construction site. Four factors were associated with contributing to work accidents. Fatigue or exhaustion (ORa : 1.53[1.03 ; 2.28]); The use of dangerous tools (ORa : 1.81 [1.22 ; 2.71]); The various laborers’ jobs (ORa : 4.78 [2.62 ; 9.21]); and seniority in the company ≥ 4 years (ORa : 2.00 [1.35 ; 2.96]). Conclusion: This study allowed us to identify the associated factors.

These can lead to a significant evolution of the microstructure and associated mechanical properties of materials used in nuclear fuel cladding structures. Therefore, the ability to capture effects of phase transformation on the material constitutive behavior is of interest during conditions of severe transient thermal loading. Whilst typical Avrami, or Johnson-Mehl-Avrami-Kolmogorov (JMAK), type models for phase transformations have been shown to have a good correlation with the behavior of Zircaloy-4 under constant heating rates, the effects of variable and fast heating rates are not fully explored. The present study utilises the results of in-situ high energy synchrotron X-ray diffraction (SXRD) measurements in order to validate the phase transformation models for Zircaloy-4 under fast variable heating rates. These models are used to assess the performance of fuel cladding structures under loss of coolant accident (LOCA) scenarios. The results indicate that simple Avrami type models can provide a reasonable indication of the phase distribution in experimental test specimens under variable fast thermal loading. However, the accuracy of these models deteriorates under the faster heating regimes, i.e., 100Cs⁻¹. The studies highlight areas for improvement of simple Avrami type models, such as the inclusion of temperature rate dependence of the JMAK n-exponent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accident" title="accident">accident</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel" title=" fuel"> fuel</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=zirconium" title=" zirconium"> zirconium</a> </p> <a href="https://publications.waset.org/abstracts/119938/modelling-phase-transformations-in-zircaloy-4-fuel-cladding-under-transient-heating-rates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119938.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Low Enrollment in Antiretroviral Treatment among Pregnant Women Screened HIV Infected in Informal Health Centers in Cameroon</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lydie%20Audrey%20Amboua%20Schouame">Lydie Audrey Amboua Schouame</a>, <a href="https://publications.waset.org/abstracts/search?q=Sylvie%20Kwedi%20Nolna"> Sylvie Kwedi Nolna</a>, <a href="https://publications.waset.org/abstracts/search?q=Antoine%20Socpa"> Antoine Socpa</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandre%20Benjamin%20Nkoum"> Alexandre Benjamin Nkoum</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Despite the struggle of the Cameroonian Ministry of Public Health against informal health centers (IHCs) because of their illegality, IHCs are booming in Cameroon and a large part of the population uses them. In 2017, more than 3.000 IHCs were counted across the country. Most of these IHCs have antenatal clinics and they screen pregnant women for HIV. However, there is no data on the Prevention of Mother-To-Child Transmission of HIV (PMTCT) in this informal health sector in Cameroon. This study aimed to investigate the initiation of Antiretroviral treatment (ART) in pregnant women screened HIV positive in IHCs and associated factors. Methods: From January 01, 2018, to June 30, 2020, we carried out a cohort study of pregnant women attending their first antenatal visit and screened HIV positive in informal health centers in the cities of Douala and Ebolowa in Cameroon. Consenting participants were interviewed at two points: at least one week after delivery of the HIV result and three months later. The collected data were entered into Kobo collected and analyzed in SPSS V23.0 software. Results: A total of 182 HIV-infected pregnant women were enrolled in the study. The median age at enrollment was 30 years (IQR, 24-34) and the median gestational age at first ANC was 25 weeks (IQR, 19-31). Overall 61% (111/182) had a secondary level of education, 65% (118/182) were married/in a common-law relationship and 69% (126/182) had no income activity. At their first ANC, 91% (166/182) were naïve to ARV treatment. Among them, only 45% (74/166) initiated ART. The median delay in initiating ARV treatment was 5 days (IQR, 0-25). Of those who have started ART, only 64% (48/74) remained on treatment 3 months later. Conclusion: In order to eliminate mother-to-child transmission of HIV, attention should be paid to IHCs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=informal%20health%20centers" title="informal health centers">informal health centers</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20immunodeficiency" title=" human immunodeficiency"> human immunodeficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=antiretroviral%20treatment" title=" antiretroviral treatment"> antiretroviral treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnant%20women" title=" pregnant women"> pregnant women</a> </p> <a href="https://publications.waset.org/abstracts/146187/low-enrollment-in-antiretroviral-treatment-among-pregnant-women-screened-hiv-infected-in-informal-health-centers-in-cameroon" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146187.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">155</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> A Study on Interaction between Traditional Culture and Modern Womenswear</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yu-Wei%20Chu">Yu-Wei Chu</a>, <a href="https://publications.waset.org/abstracts/search?q=Marie%20Aja-Herrera"> Marie Aja-Herrera</a>, <a href="https://publications.waset.org/abstracts/search?q=Denis%20Antoine"> Denis Antoine</a>, <a href="https://publications.waset.org/abstracts/search?q=Mengjie%20Di"> Mengjie Di</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this paper is to explore the innovative perspective of the local traditional culture of garments from different continents. The relationship between the local culture, the indigenous traditional technique of textile manufacture, and modern womenswear will be investigated. This will include exploring and discussing traditional techniques to create textiles reflecting different cultures and relevant handicrafts, including the history of these different peoples and regions. However, along with the improvement of technology, the diversity of culture is usually unified into a single aesthetic element, which makes fashion lack traditional cultural layers. Local cultural awareness has been gradually emerging in womenswear in recent years with the strong sweep of globalization. The possible loss of traditional art and crafts became an awareness for different cultures, who realized the necessity to protect and preserve their individual uniqueness. Modern womenswear is one of the largest markets in the fashion and apparel marketplace. Therefore, the commonalities of traditional textiles and garments for modern womenswear will be researched. Localized traditional fabrics have some elements, such as weaving techniques and other related crafts, in common with more modern manufacturing methods. In addition, the common point of traditional clothing is the use of draping, construction, and fabric manipulation. This paper aims to explore these factors, as discussed above, and also apply, in an innovative and creative manner, some of these traditional arts and crafts to modern womenswear. The combination of textile manipulation and different construction techniques can support the development of innovative womenswear to include a diversity of aesthetics. The main contribution of the paper is to find out the solution to bring local culture into the formal womenswear market with modern aesthetics to realize the ideal of traditional culture reconstruction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=traditional%20culture" title="traditional culture">traditional culture</a>, <a href="https://publications.waset.org/abstracts/search?q=modern%20womenswear" title=" modern womenswear"> modern womenswear</a>, <a href="https://publications.waset.org/abstracts/search?q=diversity" title=" diversity"> diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=aesthetics" title=" aesthetics"> aesthetics</a> </p> <a href="https://publications.waset.org/abstracts/164637/a-study-on-interaction-between-traditional-culture-and-modern-womenswear" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164637.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">114</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> Hepatic Regenerative Capacity after Acetaminophen-Induced Liver Injury in Mouse Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20F.%20Hamid">N.

The mouse model of APAP has been extensively used for studies on pathogenesis and intervention of drug induced liver injury based on the CytP450 mediated formation of N-acetyl-p-benzo-quinoneimine and, more recently, as model for mechanism based biomarkers. Delay of the fasted CD1 mice to rebound to the basal level of hepatic GSH compare to fed mice is reported in this study. Histologically, 15 hours fasted mice prior to APAP treatment leading to overall more intense cell loss with no evidence of apoptosis as compared to non-fasted mice, where the apoptotic cells were clearly seen on cleaved caspase-3 immunostaining. After 15 hours post APAP administration, hepatocytes underwent stage of recovery with evidence of mitotic figures in fed mice and return to completely no histological difference to control at 24 hours. On the contrary, the evidence of ongoing cells damage and inflammatory cells infiltration are still present on fasted mice until the end of the study. To further measure the regenerative capacity of the hepatocytes, the inflammatory mediators of cytokines that involved in the progression or regression of the toxicity like TNF-α and IL-6 in liver and spleen using RT-qPCR were also included. Yet, quantification of proliferating cell nuclear antigen (PCNA) has demonstrated the time for hepatic regenerative in fasted is longer than that to fed mice.

In this regard, a multi-objective optimization procedure is proposed for the optimal sizing of the hydropower plants, and NSGAII is employed as the optimization algorithm. Annual generated energy and investment cost are considered as the objective functions, and number of generator units (<em>n</em>) and nominal turbine flow rate (<em>Q<sub>T</sub></em>) constitute the decision variables. Site of Yeripao in Benin is considered as the case study. We have categorized the river of this site using its environmental characteristics: gross head, and first quartile, median, third quartile and mean of flow. Effects of each decision variable on the objective functions are analysed. The results gave Pareto Front which represents the trade-offs between annual energy generation and the investment cost of hydropower plants, as well as the recommended optimal solutions. We noted that with the increase of the annual energy generation, the investment cost rises. Thus, maximizing energy generation is contradictory with minimizing the investment cost. Moreover, we have noted that the solutions of Pareto Front are grouped according to the number of generator units (<em>n)</em>. The results also illustrate that the costs per kWh are grouped according to the <em>n</em> and rise with the increase of the nominal turbine flow rate. The lowest investment costs per kWh are obtained for <em>n</em> equal to one and are between 0.065 and 0.180 €/kWh. Following the values of n (equal to 1, 2, 3 or 4), the investment cost and investment cost per kWh increase almost linearly with increasing the nominal turbine flowrate while annual generated. Energy increases logarithmically with increasing of the nominal turbine flowrate. This study made for the Yeripao river can be applied to other rivers with their own characteristics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydropower%20plant" title="hydropower plant">hydropower plant</a>, <a href="https://publications.waset.org/abstracts/search?q=investment%20cost" title=" investment cost"> investment cost</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-objective%20optimization" title=" multi-objective optimization"> multi-objective optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=number%20of%20generator%20units" title=" number of generator units"> number of generator units</a> </p> <a href="https://publications.waset.org/abstracts/103977/multi-objective-optimization-of-run-of-river-small-hydropower-plants-considering-both-investment-cost-and-annual-energy-generation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103977.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">157</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> Communication Barriers and Challenges for Accessing Autism Care: Conventional Versus Alternative Medicine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20D.%20Antoine">M.

This study aimed to describe how communication occurs through the first year following an autism spectrum disorder (ASD) diagnosis to identify challenges and potential barriers to communication within the healthcare system in Ottawa, Canada. From an ecological perspective, we collected qualitative data through 12 semi-structured interviews with six parents/caregivers, three conventional providers (e.g., family doctor, neurodevelopmental pediatrician, psychologist), and three alternative practitioners (e.g., naturopath, occupational therapist, speech and language pathologist) operating in Ottawa. We interpreted the data using thematic analysis. Findings revealed communication challenges between the parents/caregivers and conventional providers while they experience better communication flow with fewer challenges in alternative care settings. However, parents/caregivers are the only links between the health professionals of both streams. From the five contexts examined: organizational, interpersonal, media, cultural, and political-legal, we found four themes (provider knowledge, care integration, flexible care, and time constraints) underlining specific barriers to communication flow between the parties involved in the care of autistic children. The increasing interest in alternative medicine is forcing changes in the healthcare system. Communications occur outside the norms making openings for better communication and information-sharing increasingly essential. Within the identified themes in the current study, the necessity for better communication between all parties involved in the care of autistic children is evident. More ASD and CAM-related training for providers would support effective parent/caregiver-provider communication. The findings of the current study contribute to a better understanding of the role of communication in the care management of autism, which has implications for effective autism care. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alternative%20medicine" title="alternative medicine">alternative medicine</a>, <a href="https://publications.waset.org/abstracts/search?q=autism%20care%20management" title=" autism care management"> autism care management</a>, <a href="https://publications.waset.org/abstracts/search?q=autism%20spectrum%20disorder" title=" autism spectrum disorder"> autism spectrum disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=conventional%20medicine" title=" conventional medicine"> conventional medicine</a>, <a href="https://publications.waset.org/abstracts/search?q=parent-provider%20communication" title=" parent-provider communication"> parent-provider communication</a> </p> <a href="https://publications.waset.org/abstracts/144613/communication-barriers-and-challenges-for-accessing-autism-care-conventional-versus-alternative-medicine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144613.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">16</span> Central Vascular Function and Relaxibility in Beta-thalassemia Major Patients vs. Sickle Cell Anemia Patients by Abdominal Aorta and Aortic Root Speckle Tracking Echocardiography</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gehan%20Hussein">Gehan Hussein</a>, <a href="https://publications.waset.org/abstracts/search?q=Hala%20Agha"> Hala Agha</a>, <a href="https://publications.waset.org/abstracts/search?q=Rasha%20Abdelraof"> Rasha Abdelraof</a>, <a href="https://publications.waset.org/abstracts/search?q=Marina%20George"> Marina George</a>, <a href="https://publications.waset.org/abstracts/search?q=Antoine%20Fakhri"> Antoine Fakhri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: β-Thalassemia major (TM) and sickle cell disease (SCD) are inherited hemoglobin disorders resulting in chronic hemolytic anemia. Cardiovascular involvement is an important cause of morbidity and mortality in these groups of patients. The narrow border is between overt myocardial dysfunction and clinically silent left ventricular (LV) and / or right ventricular (RV) dysfunction in those patients. 3 D Speckle tracking echocardiography (3D STE) is a novel method for the detection of subclinical myocardial involvement. We aimed to study myocardial affection in SCD and TM using 3D STE, comparing it with conventional echocardiography, correlate it with serum ferritin level and lactate dehydrogenase (LDH). Methodology: Thirty SCD and thirty β TM patients, age range 4-18 years, were compared to 30 healthy age and sex matched control group. Cases were subjected to clinical examination, laboratory measurement of hemoglobin level, serum ferritin, and LDH. Transthoracic color Doppler echocardiography, 3D STE, tissue Doppler echocardiography, and aortic speckle tracking were performed. Results: significant reduction in global longitudinal strain (GLS), global circumferential strain (GCS), and global area strain (GAS) in SCD and TM than control (P value <0.001) there was significantly lower aortic speckle tracking in patients with TM and SCD than control (P value< 0.001). LDH was significantly higher in SCD than both TM and control and it correlated significantly positive mitral inflow E, (p value:0.022 and 0.072. r: 0.416 and -0.333 respectively) lateral E/E’ (p value.<0.001and 0.818. r. 0.618 and -0. 044.respectively) and septal E/E’ (p value 0.007 and 0.753& r value 0.485 and -0.060 respectively) in SCD but not TM and significant negative correlation between LDH and aortic root speckle tracking (value 0.681& r. -0.078.). The potential diagnostic accuracy of LDH in predicting vascular dysfunction as represented by aortic root GCS with a sensitivity 74% and aortic root GCS was predictive of LV dysfunction in SCD patients with sensitivity 100% Conclusion: 3D STE LV and RV systolic dysfunction in spite of their normal values by conventional echocardiography. SCD showed significantly lower right ventricular dysfunction and aortic root GCS than TM and control.

The application of municipal sewage sludge or biosolids (MBS) which contain metal immobilizing agents on coarse-textured soils could improve the metal sorption capacity of the low-CEC soils. The purpose of this experiment was to evaluate the sorption of Zn in surface samples (0-15 cm) of six Quebec (Canada) soils amended with MBS (pH 6.9) from Val d’Or (Quebec, Canada). Soil samples amended with increasing amounts (0 to 20%) of MBS were equilibrated with various amounts of Zn as ZnCl2 in 0.01 M CaCl2 for 48 hours at room temperature. Sorbed Zn was calculated from the difference between the initial and final Zn concentration in solution. Zn sorption data conformed to the linear form of Freundlich equation. The amount of sorbed Zn increased considerably with increasing MBS rate. Analysis of variance revealed a highly significant effect (p ≤ 0.001) of soil texture and MBS rate on the amount of sorbed Zn. The average values of the Zn-sorption capacity of MBS-amended coarse-textured soils were lower than those of MBS-amended fine textured soils. The two sandy soils (86-99% sand) amended with MBS retained 2- to 5-fold Zn than those without MBS (control). Significant Pearson correlation coefficients between the Zn sorption isotherm parameter, i.e. the Freundlich sorption isotherm (KF), and commonly measured physical and chemical entities were obtained. Among all the soil properties measured, soil pH gave the best significant correlation coefficients (p ≤ 0.001) for soils receiving 0, 5 and 10% MBS. Furthermore, KF values were positively correlated with soil clay content, exchangeable basic cations (Ca, Mg or K), CEC and clay content to CEC ratio. From these results, it can be concluded that (i) municipal biosolids provide sorption sites that have a strong affinity for Zn, (ii) both soil texture, especially clay content, and soil pH are the main factors controlling anthropogenic Zn sorption in the municipal biosolids-amended soils, and (iii) the effect of municipal biosolids on Zn sorption will be more pronounced for a sandy soil than for a clay soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metal" title="metal">metal</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling" title=" recycling"> recycling</a>, <a href="https://publications.waset.org/abstracts/search?q=sewage%20sludge" title=" sewage sludge"> sewage sludge</a>, <a href="https://publications.waset.org/abstracts/search?q=trace%20element" title=" trace element"> trace element</a> </p> <a href="https://publications.waset.org/abstracts/37762/zinc-sorption-by-six-agricultural-soils-amended-with-municipal-biosolids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37762.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">284</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> Valorization of Plastic and Cork Wastes in Design of Composite Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Svetlana%20Petlitckaia">Svetlana Petlitckaia</a>, <a href="https://publications.waset.org/abstracts/search?q=Toussaint%20Barboni"> Toussaint Barboni</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul-Antoine%20Santoni"> Paul-Antoine Santoni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Plastic is a revolutionary material. However, the pollution caused by plastics damages the environment, human health and the economy of different countries. It is important to find new ways to recycle and reuse plastic material. The use of waste materials as filler and as a matrix for composite materials is receiving increasing attention as an approach to increasing the economic value of streams. In this study, a new composite material based on high-density polyethylene (HDPE) and polypropylene (PP) wastes from bottle caps and cork powder from unused cork (virgin cork), which has a high capacity for thermal insulation, was developed. The composites were prepared with virgin and modified cork. The composite materials were obtained through twin-screw extrusion and injection molding. The composites were produced with proportions of 0 %, 5 %, 10 %, 15 %, and 20 % of cork powder in a polymer matrix with and without coupling agent and flame retardant. These composites were investigated in terms of mechanical, structural and thermal properties. The effect of cork fraction, particle size and the use of flame retardant on the properties of composites were investigated. The properties of samples elaborated with the polymer and the cork were compared to them with the coupling agent and commercial flame retardant. It was observed that the morphology of HDPE/cork and PP/cork composites revealed good distribution and dispersion of cork particles without agglomeration. The results showed that the addition of cork powder in the polymer matrix reduced the density of the composites. However, the incorporation of natural additives doesn’t have a significant effect on water adsorption. Regarding the mechanical properties, the value of tensile strength decreases with the addition of cork powder, ranging from 30 MPa to 19 MPa for PP composites and from 19 MPa to 17 MPa for HDPE composites. The value of thermal conductivity of composites HDPE/cork and PP/ cork is about 0.230 W/mK and 0.170 W/mK, respectively. Evaluation of the flammability of the composites was performed using a cone calorimeter. The results of thermal analysis and fire tests show that it is important to add flame retardants to improve fire resistance. The samples elaborated with the coupling agent and flame retardant have better mechanical properties and fire resistance. The feasibility of the composites based on cork and PP and HDPE wastes opens new ways of valorizing plastic waste and virgin cork. The formulation of composite materials must be optimized. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20materials" title="composite materials">composite materials</a>, <a href="https://publications.waset.org/abstracts/search?q=cork%20and%20polymer%20wastes" title=" cork and polymer wastes"> cork and polymer wastes</a>, <a href="https://publications.waset.org/abstracts/search?q=flammability" title=" flammability"> flammability</a>, <a href="https://publications.waset.org/abstracts/search?q=modificated%20cork" title=" modificated cork"> modificated cork</a> </p> <a href="https://publications.waset.org/abstracts/167429/valorization-of-plastic-and-cork-wastes-in-design-of-composite-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167429.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">88</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Occupational Exposure and Contamination to Antineoplastic Drugs of Healthcare Professionals in Mauritania</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antoine%20Villa">Antoine Villa</a>, <a href="https://publications.waset.org/abstracts/search?q=Moustapha%20Mohamedou"> Moustapha Mohamedou</a>, <a href="https://publications.waset.org/abstracts/search?q=Florence%20Pilliere"> Florence Pilliere</a>, <a href="https://publications.waset.org/abstracts/search?q=Catherine%20Verdun-Esquer"> Catherine Verdun-Esquer</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Molimard"> Mathieu Molimard</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Sidatt%20Cheikh%20El%20Moustaph"> Mohamed Sidatt Cheikh El Moustaph</a>, <a href="https://publications.waset.org/abstracts/search?q=Mireille%20Canal-Raffin"> Mireille Canal-Raffin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Context: In Mauritania, the activity of the National Center of Oncology (NCO) has steadily risen leading to an increase in the handling of antineoplastic drugs (AD) by healthcare professionals. In this context, the AD contamination of those professionals is a major concern for occupational physicians. It has been evaluated using biological monitoring of occupational exposure (BMOE). Methods: The intervention took place in 2015, in 2 care units, and evaluated nurses preparing and/or infusing AD and agents in charge of hygiene. Participants provided a single urine sample, at the end of the week, at the end of their shift. Five molecules were sought using specific high sensitivity methods (UHPLC-MS/MS) with very low limits of quantification (LOQ) (cyclophosphamide (CP), Ifosfamide (IF), methotrexate (MTX): 2.5ng/L; doxorubicin (Doxo): 10ng/L; α-fluoro-β-alanine (FBAL, 5-FU metabolite): 20ng/L). A healthcare worker was considered as 'contaminated' when an AD was detected at a urine concentration equal to or greater than the LOQ of the analytical method or at trace concentration. Results: Twelve persons participated (6 nurses, 6 agents in charge of hygiene). Twelve urine samples were collected and analyzed. The percentage of contamination was 66.6% for all participants (n=8/12), 100% for nurses (6/6) and 33% for agents in charge of hygiene (2/6). In 62.5% (n=5/8) of the contaminated workers, two to four of the AD were detected in the urine. CP was found in the urine of all contaminated workers. FBAL was found in four, MTX in three and Doxo in one. Only IF was not detected. Urinary concentrations (all drugs combined) ranged from 3 to 844 ng/L for nurses and from 3 to 44 ng/L for agents in charge of hygiene. The median urinary concentrations were 87 ng/L, 15.1 ng/L and 4.4 ng/L for FBAL, CP and MTX, respectively. The Doxo urinary concentration was found 218ng/L. Discussion: There is no current biological exposure index for the interpretation of AD contamination. The contamination of these healthcare professionals is therefore established by the detection of one or more AD in urine. These urinary contaminations are higher than the LOQ of the analytical methods, which must be as low as possible. Given the danger of AD, the implementation of corrective measures is essential for the staff. Biological monitoring of occupational exposure is the most reliable process to identify groups at risk, tracing insufficiently controlled exposures and as an alarm signal. These results show the necessity to educate professionals about the risks of handling AD and/or to care for treated patients. <p class="card-text"><strong>Keywords:</strong> <a
