Correlations studies between these distances and Raw measured by body plethysmography (BP) showed that these RIP variables could be potentially used in airway resistance assessment in patients with airway obstruction. Significant correlation was found between ΔAd and airway resistance changes (ΔRaw) (r= 0.407, p=0.03) and not between ΔSd and ΔRaw. This assumption was supported by the high correlations found when relating the average of ΔS and of ΔA calculated on successive intervals of ΔRaw, with the ΔRaw averages calculated for each interval (r= 0.892, p= 0.006 and r= 0.857, p=0.006 respectively). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airways%20obstruction" title="airways obstruction">airways obstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=distances" title=" distances"> distances</a>, <a href="https://publications.waset.org/abstracts/search?q=respiratory%20inductive%20plethysmography" title=" respiratory inductive plethysmography"> respiratory inductive plethysmography</a>, <a href="https://publications.waset.org/abstracts/search?q=reversibility%20test" title=" reversibility test "> reversibility test </a> </p> <a href="https://publications.waset.org/abstracts/11007/study-for-a-non-invasive-method-of-respiratory-resistance-measurement-among-patients-with-airways-obstructions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11007.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">453</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> Airway Resistance Evaluation by Respiratory İnductive Plethysmography in Subjects with Airway Obstructions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aicha%20Laouani">Aicha Laouani</a>, <a href="https://publications.waset.org/abstracts/search?q=Sonia%20Rouatbi"> Sonia Rouatbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Saad%20%20Saguem"> Saad Saguem</a>, <a href="https://publications.waset.org/abstracts/search?q=Gila%20Benchetrit"> Gila Benchetrit</a>, <a href="https://publications.waset.org/abstracts/search?q=Pascale%20calabrese"> Pascale calabrese</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A new approach based on respiratory inductive plethysmography (RIP) signal analysis has been used for bronchoconstriction changes evaluation in 50 healthy controls and in 44 adults with moderate bronchial obstruction treated with a bronchodilatation protocol. Thoracic and abdominal motions were recorded ( 5 min) by RIP. For each recording the thoracoabdominal signals were analysed and a mean distance (D) was calculated. Airway resistance (Raw) and spirometric data were measured with a body plethysmograph. The results showed that both D and Raw were higher in subjects compared to the healthy group. Significant decreases of D and Raw were also observed after bronchodilatation in the obstructive group. There was also a positive and a significant correlation between D and Raw in subjects before and after bronchodilatation. This D calculated from RIP Signals could be used as a non invasive tool for continuous monitoring of bronchoconstriction changes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airway%20resistance" title="airway resistance">airway resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=bronchoconstriction" title=" bronchoconstriction"> bronchoconstriction</a>, <a href="https://publications.waset.org/abstracts/search?q=thorax" title=" thorax"> thorax</a>, <a href="https://publications.waset.org/abstracts/search?q=respiratory%20inductive%20plethysmography" title=" respiratory inductive plethysmography"> respiratory inductive plethysmography</a> </p> <a href="https://publications.waset.org/abstracts/40110/airway-resistance-evaluation-by-respiratory-inductive-plethysmography-in-subjects-with-airway-obstructions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40110.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">335</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> CONDUCTHOME: Gesture Interface Control of Home Automation Boxes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Branstett">J.

PdM is a prominent strategy consisting of all the operational techniques and actions required to ensure machine availability and to prevent a machine-down failure. One of the challenges with PdM approach is to design and develop of an embedded smart system to enable the health status of the machine. The proposed approach allows screening simultaneously multiple connected machines, thus providing real-time monitoring that can be adopted with maintenance management. This is achieved by applying temporal feature engineering techniques and training an ensemble of classification algorithms to predict Remaining Useful Lifetime of woodworking machines. The effectiveness of the methodology is demonstrated by testing an independent sample of additional woodworking machines without presenting machine down event. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=predictive%20maintenance" title="predictive maintenance">predictive maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=connected%20machines" title=" connected machines"> connected machines</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a> </p> <a href="https://publications.waset.org/abstracts/98461/predicting-machine-down-of-woodworking-industrial-machines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98461.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">226</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> Proposals for the Thermal Regulation of Buildings in Algeria: A New Energy Label for Social Housing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marco%20Morini">Marco Morini</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolandrea%20Calabrese"> Nicolandrea Calabrese</a>, <a href="https://publications.waset.org/abstracts/search?q=Dario%20Chello"> Dario Chello</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Despite the international commitment of Algeria towards the development of energy efficiency and renewable energy in the country, the internal energy demand has been continuously growing during the last decade due to the substantial increase of population and of living conditions, which in turn has led to an unprecedented expansion of the residential building sector. The thermal building regulation is the technical document that establishes the calculation framework for the thermal performance of buildings in Algeria, setting up minimum obligatory targets for the thermal performance of new buildings. An update of this regulation is due in the coming years, and this paper discusses some proposals in this regard, with the aim to improve the energy efficiency of the building sector, particularly with regard to social housing. In particular, it proposes a methodology for drafting an energy performance label of new Algerian residential buildings, moving from the results of the thermal compliance verification and sizing of technical systems as defined in the RTB. Such an energy performance label – whose calculation method is briefly described in the paper – aims to raise citizens' awareness of the benefits of energy efficiency. It can represent the first step in a process of integrating technical installations into the calculation of the energy performance of buildings in Algeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building" title="building">building</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20certification" title=" energy certification"> energy certification</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title=" energy efficiency"> energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20housing" title=" social housing"> social housing</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20cooperation" title=" international cooperation"> international cooperation</a>, <a href="https://publications.waset.org/abstracts/search?q=Mediterranean%20region" title=" Mediterranean region"> Mediterranean region</a> </p> <a href="https://publications.waset.org/abstracts/138652/proposals-for-the-thermal-regulation-of-buildings-in-algeria-a-new-energy-label-for-social-housing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138652.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">144</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> U11 Functionalised Luminescent Gold Nanoclusters for Pancreatic Tumor Cells Labelling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Regina%20M.%20Chiechio">Regina M.

These applications require control of their delivery and interaction with cells; for this reason, the surface chemistry of Au NCs is essential to determine their interaction with the targeted biological objects. Here we demonstrate their ability as markers of pancreatic tumor cells. By functionalizing the surface of the NCs with a recognition peptite (U11), the nanostructures are able to preferentially bind to pancreatic cancer cells via a receptor (uPAR) overexpressed by these cells. Furthermore, the NCs can mark even the nucleus without the need of fixing the cells. These nanostructures can therefore be used as a non-toxic, multivalent luminescent platform, capable of selectively recognizing tumor cells for bioimaging, drug delivery, and radiosensitization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gold%20nanoclusters" title="gold nanoclusters">gold nanoclusters</a>, <a href="https://publications.waset.org/abstracts/search?q=luminescence" title=" luminescence"> luminescence</a>, <a href="https://publications.waset.org/abstracts/search?q=biomarkers" title=" biomarkers"> biomarkers</a>, <a href="https://publications.waset.org/abstracts/search?q=pancreatic%20cancer" title=" pancreatic cancer"> pancreatic cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=biomedical%20applications" title=" biomedical applications"> biomedical applications</a>, <a href="https://publications.waset.org/abstracts/search?q=bioimaging" title=" bioimaging"> bioimaging</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorescent%20probes" title=" fluorescent probes"> fluorescent probes</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20delivery" title=" drug delivery"> drug delivery</a> </p> <a href="https://publications.waset.org/abstracts/146031/u11-functionalised-luminescent-gold-nanoclusters-for-pancreatic-tumor-cells-labelling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146031.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">151</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> Thermal and Dielectric Breakdown Criterium for Low Voltage Switching Devices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Merciris">Thomas Merciris</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Masquere"> Mathieu Masquere</a>, <a href="https://publications.waset.org/abstracts/search?q=Yann%20Cressault"> Yann Cressault</a>, <a href="https://publications.waset.org/abstracts/search?q=Pascale%20Petit"> Pascale Petit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The goal of an alternative current (AC) switching device is to allow the arc (created during the opening phase of the contacts) to extinguish at the current zero. The plasma temperature rate of cooling down, the electrical characteristic of the arc (current-voltage), and the rise rate of the transient recovery voltage (TRV) are critical parameters which influence the performance of a switching device. To simulate the thermal extinction of the arc and to obtain qualitative data on the processes responsible for this phenomenon, a 1D MHD fluid model in the air was developed and coupled to an external electric circuit. After thermal extinction, the dielectric strength of the hot air (< 4kK) was then estimated by the Bolsig+ software and the critical electric fields method with the temperature obtained by the MHD simulation. The influence of copper Cu and silver Ag vapors was investigated on the thermal and dielectric part of the simulation with various current forms (100A to 1kA). Finally, those values of dielectric strength have been compared to the experimental values obtained in the case of two separating silver contacts. The preliminary results seem to indicate the dielectric strength after multiples hundreds of microseconds is the same order of magnitude as experimentally found. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MHD%20simulation" title="MHD simulation">MHD simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=dielectric%20recovery" title=" dielectric recovery"> dielectric recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=Bolsig%2B" title=" Bolsig+"> Bolsig+</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20vapors" title=" silver vapors"> silver vapors</a>, <a href="https://publications.waset.org/abstracts/search?q=copper%20vapors" title=" copper vapors"> copper vapors</a>, <a href="https://publications.waset.org/abstracts/search?q=breakers" title=" breakers"> breakers</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20arc" title=" electric arc"> electric arc</a> </p> <a href="https://publications.waset.org/abstracts/156604/thermal-and-dielectric-breakdown-criterium-for-low-voltage-switching-devices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156604.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">16</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.

Due to the planned electrification of European vehicles, cobalt needs are expending – and resources are limited. To meet the needs in cobalt to come, it is necessary to develop new efficient ways to recycle cobalt. One of the biggest sources comes from old electrical vehicles batteries (batteries sold in 2019: 500 000 tons of waste to be). A closed loop process of cobalt recycling has been developed and this presentation aims to present the selectivity mechanism of cobalt over manganese and nickel in solution. Cobalt precipitation as a ZIF material (Zeolitic Imidazolate framework) from a starting solution composed of equimolar nickel, manganese and cobalt is studied. A 2-MeIm (2-methylimidazole) linker is introduced in a multimetallic Ni, Mn, Co solution and the resulting ZIF-67 is 100% pure Co among its metallic centers. Selectivity of Co over Ni is experimentally studied and DFT modelisation calculation are conducted to understand the geometry of ligand-metal-solvent complexes in solution. Selectivity of Co over Mn is experimentally studied, and DFT modelisation calcucation are conducted to understand the link between pKa of the ligand and precipitration of Mn impurities within the final material. Those calculation open the way to other ligand being used in the same process, with more efficiency. Experimental material are synthetized from bimetallic (Ni²⁺/Co²⁺, Mn²⁺/Co²⁺, Mn²⁺/Ni²⁺) solutions. Their crystallographic structure is analysed by XRD diffraction (Brüker AXS D8 diffractometer, Cu anticathode). Morphology is studied by scanning electron microscopy, using a LEO 1530 FE-SEM microscope. The chemical analysis is performed by using ICP-OES (Agilent Technologies 700 series ICP-OES). Modelisation calculation are DFT calculation (density functional theory), using B3LYP, conducted with Orca 4.2. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MOFs" title="MOFs">MOFs</a>, <a href="https://publications.waset.org/abstracts/search?q=ZIFs" title=" ZIFs"> ZIFs</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling" title=" recycling"> recycling</a>, <a href="https://publications.waset.org/abstracts/search?q=closed-loop" title=" closed-loop"> closed-loop</a>, <a href="https://publications.waset.org/abstracts/search?q=cobalt" title=" cobalt"> cobalt</a>, <a href="https://publications.waset.org/abstracts/search?q=li-ion%20batteries" title=" li-ion batteries"> li-ion batteries</a> </p> <a href="https://publications.waset.org/abstracts/154201/selectivity-mechanism-of-cobalt-precipitation-by-an-imidazole-linker-from-an-old-battery-solution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154201.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">137</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Effect of Environmental Parameters on the Water Solubility of the Polycyclic Aromatic Hydrocarbons and Derivatives using Taguchi Experimental Design Methodology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pranudda%20Pimsee">Pranudda Pimsee</a>, <a href="https://publications.waset.org/abstracts/search?q=Caroline%20Sablayrolles"> Caroline Sablayrolles</a>, <a href="https://publications.waset.org/abstracts/search?q=Pascale%20De%20Caro"> Pascale De Caro</a>, <a href="https://publications.waset.org/abstracts/search?q=Julien%20Guyomarch"> Julien Guyomarch</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Lesage"> Nicolas Lesage</a>, <a href="https://publications.waset.org/abstracts/search?q=Mireille%20Montr%C3%A9jaud-Vignoles"> Mireille Montréjaud-Vignoles</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The MIGR’HYCAR research project was initiated to provide decisional tools for risks connected to oil spill drifts in continental waters. These tools aim to serve in the decision-making process once oil spill pollution occurs and/or as reference tools to study scenarios of potential impacts of pollutions on a given site. This paper focuses on the study of the distribution of polycyclic aromatic hydrocarbons (PAHs) and derivatives from oil spill in water as function of environmental parameters. Eight petroleum oils covering a representative range of commercially available products were tested. 41 Polycyclic Aromatic Hydrocarbons (PAHs) and derivate, among them 16 EPA priority pollutants were studied by dynamic tests at laboratory scale. The chemical profile of the water soluble fraction was different from the parent oil profile due to the various water solubility of oil components. Semi-volatile compounds (naphtalenes) constitute the major part of the water soluble fraction. A large variation in composition of the water soluble fraction was highlighted depending on oil type. Moreover, four environmental parameters (temperature, suspended solid quantity, salinity, and oil: water surface ratio) were investigated with the Taguchi experimental design methodology. The results showed that oils are divided into three groups: the solubility of Domestic fuel and Jet A1 presented a high sensitivity to parameters studied, meaning they must be taken into account. For gasoline (SP95-E10) and diesel fuel, a medium sensitivity to parameters was observed. In fact, the four others oils have shown low sensitivity to parameters studied. Finally, three parameters were found to be significant towards the water soluble fraction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mornitoring" title="mornitoring">mornitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=PAHs" title=" PAHs"> PAHs</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20soluble%20fraction" title=" water soluble fraction"> water soluble fraction</a>, <a href="https://publications.waset.org/abstracts/search?q=SBSE" title=" SBSE"> SBSE</a>, <a href="https://publications.waset.org/abstracts/search?q=Taguchi%20experimental%20design" title=" Taguchi experimental design"> Taguchi experimental design</a> </p> <a href="https://publications.waset.org/abstracts/4871/effect-of-environmental-parameters-on-the-water-solubility-of-the-polycyclic-aromatic-hydrocarbons-and-derivatives-using-taguchi-experimental-design-methodology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4871.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">325</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> Caregivers Burden: Risk and Related Psychological Factors in Caregivers of Patients with Parkinson’s Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pellecchia%20M.%20T.">Pellecchia M.

Caring for a person with PD is associated with an increased risk of psychiatric morbidity and persistent anxiety-depressive distress. The aim of the study is to investigate the burden on caregivers of patients with PD, through the use of multidimensional scales and to identify their personological and environmental determinants. Methods: The study has been approved by the Ethic Committee of the University of Salerno and informed consent for participation to the study was obtained from patients and their caregivers. The study was conducted at the Neurology Department of the A.O.U. "San Giovanni di Dio and Ruggi D’Aragona" of Salerno between September 2020 and May 2021. Materials: The questionnaires used were: a) Caregiver Burden Inventory - CBI a questionnaire of 24 items that allow identifying five sub-categories of burden (objective, psychological, physical, social, emotional); b) Depression Anxiety Stress Scales Short Version - DASS-21 questionnaire consisting of 21 items and valid in examining three distinct but interrelated areas (depression, anxiety and stress); c) Family Strain Questionnaire Short Form - FSQ-SF is a questionnaire of 30 items grouped in areas of increasing psychological risk (OK, R, SR, U); d) Zarit Caregiver Burden Inventory - ZBI, consisting of 22 items based on the analysis of two main factors: personal stress and pressure related to his role; e) Life Satisfaction, a single item that aims to evaluate the degree of life satisfaction in a global way using a 0-100 Likert scale. Findings: N ° 29 caregivers (M age = 55.14, SD = 9.859; 69% F) participated in the study. 20.6% of the sample had severe and severe burden (CBI score = M = 26.31; SD = 22.43) and 13.8% of participants had moderate to severe burden (ZBI). The FSQ-SF highlighted a minority of caregivers who need psychological support, in some cases urgent (Area SR and Area U). The DASS-21 results show a prevalence of stress-related symptoms (M = 10.90, SD = 10.712) compared to anxiety (M = 7.52, SD = 10.752) and depression (M = 8, SD = 10.876). There are significant correlations between some specific variables and mean test scores: retired caregivers report higher ZBI scores (p = 0.423) and lower Life Satisfaction levels (p = -0.460) than working caregivers; years of schooling show a negative linear correlation with the ZBI score (p = -0.491). The T-Test indicates that caregivers of patients with cognitive impairment are at greater risk than those of patients without cognitive impairment. Conclusions: It knows the factors that affect the burden the most would allow for early recognition of risky situations and caregivers who would need adequate support. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anxious-depressive%20axis" title="anxious-depressive axis">anxious-depressive axis</a>, <a href="https://publications.waset.org/abstracts/search?q=caregivers%E2%80%99%20burden" title=" caregivers’ burden"> caregivers’ burden</a>, <a href="https://publications.waset.org/abstracts/search?q=Parkinson%E2%80%99%20disease" title=" Parkinson’ disease"> Parkinson’ disease</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20risks" title=" psychological risks"> psychological risks</a> </p> <a href="https://publications.waset.org/abstracts/141394/caregivers-burden-risk-and-related-psychological-factors-in-caregivers-of-patients-with-parkinsons-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141394.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">215</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> The Effect of the Spinacia oleracea Extract on the Control of the Green Mold 'Penilillium digitatum' at the Post Harvested Citrus </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asma%20Chbani">Asma Chbani</a>, <a href="https://publications.waset.org/abstracts/search?q=Douaa%20Salim"> Douaa Salim</a>, <a href="https://publications.waset.org/abstracts/search?q=Josephine%20%20Al%20Alam"> Josephine Al Alam</a>, <a href="https://publications.waset.org/abstracts/search?q=Pascale%20De%20Caro"> Pascale De Caro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Penicillium digitatum, the causal agent of citrus green mold, is responsible for 90% of post-harvest losses. Chemical fungicides remain the most used products for protection against this pathogen but are also responsible for damage to human health and the environment. The aim of this study is to evaluate the ability of Spinacia oleracea extract to serve as biological control agents, an alternative to harmful synthetic fungicides, against orange decay for storing fruit caused by P. digitatum. In this study, we studied the implication of a crude extract of a green plant, Spinacia oleracea, in the protection of oranges against P. digitatum. Thus, in vivo antifungal tests as well as adhesion test were done. For in vivo antifungal test, oranges were pulverized with the prepared crude extracts at different concentrations ranged from 25 g L⁻¹ to 200 g L⁻¹, contaminated by the fungus and then observed during 8 weeks for their macroscopic changes at 24°C. For adhesion test, the adhesion index is defined as the number of Penicillium digitatum spores fixed per orange cell. An index greater than 25 is the indicator of a strong adhesion, whereas for an index less than 10, the adhesion is low. Ten orange cells were examined in triplicate for each extract, and the averages of adherent cells were calculated. Obtained results showed an inhibitory activity of the Penicillium development with the aqueous extract of dry Spinacia oleracea with a concentration of 50 g L⁻¹ considered as the minimal protective concentration. The prepared extracts showed a greater inhibition of the development of P. digitatum up to 10 weeks, even greater than the fungicide control Nystatin. Adhesion test’s results showed that the adhesion of P. digitatum spores to the epidermal cells of oranges in the presence of the crude spinach leaves extract is weak; the mean of the obtained adhesion index was estimated to 2.7. However, a high adhesion was observed with water used a negative control. In conclusion, all these results confirm that the use of this green plant highly rich in chlorophyll having several phytotherapeutic activities, could be employed as a great treatment for protection of oranges against mold and also as an alternative for chemical fungicides. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Penicillium%20digitatum" title="Penicillium digitatum">Penicillium digitatum</a>, <a href="https://publications.waset.org/abstracts/search?q=Spinacia%20oleracea" title=" Spinacia oleracea"> Spinacia oleracea</a>, <a href="https://publications.waset.org/abstracts/search?q=oranges" title=" oranges"> oranges</a>, <a href="https://publications.waset.org/abstracts/search?q=biological%20control" title=" biological control"> biological control</a>, <a href="https://publications.waset.org/abstracts/search?q=postharvest%20diseases" title=" postharvest diseases"> postharvest diseases</a> </p> <a href="https://publications.waset.org/abstracts/82068/the-effect-of-the-spinacia-oleracea-extract-on-the-control-of-the-green-mold-penilillium-digitatum-at-the-post-harvested-citrus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82068.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">172</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> Evaluating Energy Transition of a complex of buildings in a historic site of Rome toward Zero-Emissions for a Sustainable Future</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Di%20Turi">Silvia Di Turi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolandrea%20Calabrese"> Nicolandrea Calabrese</a>, <a href="https://publications.waset.org/abstracts/search?q=Francesca%20Caffari"> Francesca Caffari</a>, <a href="https://publications.waset.org/abstracts/search?q=Giulia%20Centi"> Giulia Centi</a>, <a href="https://publications.waset.org/abstracts/search?q=Francesca%20Margiotta"> Francesca Margiotta</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Murano"> Giovanni Murano</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Ronchetti"> Laura Ronchetti</a>, <a href="https://publications.waset.org/abstracts/search?q=Paolo%20Signoretti"> Paolo Signoretti</a>, <a href="https://publications.waset.org/abstracts/search?q=Lisa%20Volpe"> Lisa Volpe</a>, <a href="https://publications.waset.org/abstracts/search?q=Domenico%20Palladino"> Domenico Palladino</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recent European policies have been set ambitious targets aimed at significantly reducing CO2 emissions by 2030, with a long-term vision of transforming existing buildings into Zero-Emissions Buildings (ZEmB) by 2050. This vision represents a key point for the energy transition as the whole building stock currently accounts for 36% of total energy consumption across the Europe, mainly due to their poor energy performance. The challenge towards Zero-Emissions Buildings is particularly felt in Italy, where a significant number of buildings with historical significance or situated within protected/constrained areas can be found. Furthermore, an estimated 70% of the national building stock are built before 1976, indicating a widespread issue of poor energy performance. Addressing the energy ineƯiciency of these buildings is crucial to refining a comprehensive energy renovation approach aimed at facilitating their energy transition. In this framework the current study focuses on analysing a challenging complex of buildings to be totally restored through significant energy renovation interventions. The goal is to recover these disused buildings situated in a significant archaeological zone of Rome, contributing to the restoration and reintegration of this historically valuable site, while also oƯering insights useful for achieving zeroemission requirements for buildings within such contexts. In pursuit of meeting the stringent zero-emission requirements, a comprehensive study was carried out to assess the complex of buildings, envisioning substantial renovation measures on building envelope and plant systems and incorporating renewable energy system solutions, always respecting and preserving the historic site. An energy audit of the complex of buildings was performed to define the actual energy consumption for each energy service by adopting the hourly calculation methods. Subsequently, significant energy renovation interventions on both building envelope and mechanical systems have been examined respecting the historical value and preservation of site. These retrofit strategies have been investigated with threefold aims: 1) to recover the existing buildings ensuring the energy eƯiciency of the whole complex of buildings, 2) to explore which solutions have allowed achieving and facilitating the ZEmB status, 3) to balance the energy transition requirements with the sustainable aspect in order to preserve the historic value of the buildings and site. This study has pointed out the potentiality and the technical challenges associated with implementing renovation solutions for such buildings, representing one of the first attempt towards realizing this ambitious target for this type of building. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20conservation%20and%20transition" title="energy conservation and transition">energy conservation and transition</a>, <a href="https://publications.waset.org/abstracts/search?q=complex%20of%20buildings%20in%20historic%20site" title=" complex of buildings in historic site"> complex of buildings in historic site</a>, <a href="https://publications.waset.org/abstracts/search?q=zero-emission%20buildings" title=" zero-emission buildings"> zero-emission buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency%20recovery" title=" energy efficiency recovery"> energy efficiency recovery</a> </p> <a href="https://publications.waset.org/abstracts/183461/evaluating-energy-transition-of-a-complex-of-buildings-in-a-historic-site-of-rome-toward-zero-emissions-for-a-sustainable-future" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183461.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">9</span> Awareness and Access to Rapid Diagnostic Tests of HIV, Malaria and Tuberculosis among Rural Pregnant Women of Savannakhet Province, Lao PDR</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vanphanom%20Sychareun">Vanphanom Sychareun</a>, <a href="https://publications.waset.org/abstracts/search?q=Viengnakhone%20Vongxay"> Viengnakhone Vongxay</a>, <a href="https://publications.waset.org/abstracts/search?q=Kongmany%20Chaleunvong"> Kongmany Chaleunvong</a>, <a href="https://publications.waset.org/abstracts/search?q=Pascale%20Hancart%20Petitet"> Pascale Hancart Petitet</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Lao PDR still has challenges in preventing and managing health against risk of emerging and re-emerging diseases, particularly HIV/AIDS, tuberculosis and malaria among pregnant women. Community-based intervention for mothers requires more evidences on awareness of such diseases and access to rapid diagnostic tests. The study aims to determine the awareness of pregnant women regarding HIV, TB and Malaria, the access to rapid diagnostic test of such diseases among pregnant women of local community and their factors related. Method: This is a cross sectional study using quantitative approach to explore the awareness of pregnant women on HIV/AIDS/TB and Malaria in Savannakhet province, Lao PDR in three remote districts (Phin, Thapangthong and Atsaphone) of Savannakhet province. The study targeted group was pregnant women at the community level. Sample size for primary data collection of pregnant women was 189. Face-to-face administered questionnaires were applied. Descriptive and inferential statistics were applied to determine the associated factors with awareness of pregnant women on HIV/AIDS/TB and Malaria. This study is under the HEALTH project/ Expertise France. Result: Most of our participants were pregnant at 28 – 42 weeks (50.3%); ranged 4 – 38 weeks. Mean age of pregnant women was 24.3 years old (range: 14 - 48 years old); 15.9% of whom were at age below 19 years. Around 94.2% of respondents works were farming, 54.5% were illiterate, 74.0% were Mon-Kmer ethnic, and 60% had income lower than average. Only 56.6% that have access to ANC, 39.1% started the access to ANC during the first trimester and only 19.6% had visited the ANC for at least four times. Almost pregnant women (and 92.1% and 93.1%) had low to moderate knowledge of HIV and TB respectively, while three-fourth of pregnant women (74.6%) had low to moderate knowledge of malaria. Slightly higher than half of participants (53.4% and 52.9%) had easy access to HIV and TB respectively ; while 72.5% had easy access to malaria. Majority of participants knew where to get tested for malaria (73.5%) and TB (54.5%), but 73.5% did not know where to get tested for HIV. Very few pregnant women (1.6%, 2.1% and 8.5%) experienced having tested for HIV/TB/malaria. respectively. Factors associated with awareness on HIV were occupation as staff, business (OR:5.9; 95% CI:1.2-28.1), upper secondary education (OR: 14.6; 95% CI:3.1-69.2); Mone-Khmer ethnic (OR: 0.4, 95% CI: 0.2-0.8); and attending ANC more than 4 times (OR:4.1, 95%:1.7-9.7). Factors associated with awareness on TB were occupation as staff, business (OR:2.4; 95% CI: 0.7-8.0), upper secondary education (OR: 6.2; 95% CI: 1.9-20.5); Mone-Khmer ethnic (OR: 0.5, 95% CI:0.3-0.9); attending ANC more than 4 times (OR:2.8, 95%:1.2-6.4). Factors associated with awareness on malaria were upper secondary education (OR: 18.1; 95% CI: 2.3-142.9); Mone-Khmer ethnic (OR: 0.2, 95% CI:0.1-0.4); attending ANC more than 4 times (OR:3.6, 95%:1.5-8.8). Conclusion: A very low awareness on HIV, TB and malaria among pregnant women in rural community of Savannakhet triggers the requirement of comprehensive public health intervention on awareness and access to prevention against emerging diseases for all pregnant women. Future intervention should focus on providing more knowledge to pregnant women during ANC and encouraging them to attend ANC more than 4 times. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pregnant%20women" title="pregnant women">pregnant women</a>, <a href="https://publications.waset.org/abstracts/search?q=HIV" title=" HIV"> HIV</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculosis" title=" tuberculosis"> tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=malaria" title=" malaria"> malaria</a>, <a href="https://publications.waset.org/abstracts/search?q=awareness" title=" awareness"> awareness</a>, <a href="https://publications.waset.org/abstracts/search?q=Laos" title=" Laos"> Laos</a> </p> <a href="https://publications.waset.org/abstracts/172523/awareness-and-access-to-rapid-diagnostic-tests-of-hiv-malaria-and-tuberculosis-among-rural-pregnant-women-of-savannakhet-province-lao-pdr" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172523.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">87</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> Journal Bearing with Controllable Radial Clearance, Design and Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Majid%20Rashidi">Majid Rashidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahrbanoo%20Farkhondeh%20Biabnavi"> Shahrbanoo Farkhondeh Biabnavi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The hydrodynamic instability phenomenon in a journal bearing may occur by either a reduction in the load carried by journal bearing, by an increase in the journal speed, by change in the lubricant viscosity, or a combination of these factors. The previous research and development work done to overcome the instability issue of journal bearings, operating in hydrodynamic lubricate regime, can be categorized as follows: A) Actively controlling the bearing sleeve by using piezo actuator, b) Inclusion of strategically located and shaped internal grooves within inner surface of the bearing sleeve, c) Actively controlling the bearing sleeve using an electromagnetic actuator, d)Actively and externally pressurizing the lubricant within a journal bearing set, and e)Incorporating tilting pads within the inner surface of the bearing sleeve that assume different equilibrium angular position in response to changes in the bearing design parameter such as speed and load. This work presents an innovative design concept for a 'smart journal bearing' set to operate in a stable hydrodynamic lubrication regime, despite variations in bearing speed, load, and its lubricant viscosity. The proposed bearing design allows adjusting its radial clearance for an attempt to maintain a stable bearing operation under those conditions that may cause instability for a bearing with a fixed radial clearance. The design concept allows adjusting the radial clearance at small increments in the order of 0.00254 mm. This is achieved by axially moving two symmetric conical rigid cavities that are in close contact with the conically shaped outer shell of a sleeve bearing. The proposed work includes a 3D model of the bearing that depicts the structural interactions of the bearing components. The 3D model is employed to conduct finite element Analyses to simulate the mechanical behavior of the bearing from a structural point of view. The concept of controlling of the radial clearance, as presented in this work, is original and has not been proposed and discuss in previous research. A typical journal bearing was analyzed under a set of design parameters, namely r =1.27 cm (journal radius), c = 0.0254 mm (radial clearance), L=1.27 cm (bearing length), w = 445N (bearing load), μ = 0.028 Pascale (lubricant viscosity). A shaft speed as 3600 r.p.m was considered, and the mass supported by the bearing, m, is set to be 4.38kg. The Summerfield Number associated with the above bearing design parameters turn to be, S=0.3. These combinations resulted in stable bearing operation. Subsequently, the speed was postulated to increase from 3600 r.p.mto 7200 r.p.m; the bearing was found to be unstable under the new increased speed. In order to regain stability, the radial clearance was increased from c = 0.0254 mm to0.0358mm. The change in the radial clearance was shown to bring the bearing back to stable an operating condition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adjustable%20clearance" title="adjustable clearance">adjustable clearance</a>, <a href="https://publications.waset.org/abstracts/search?q=bearing" title=" bearing"> bearing</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrodynamic" title=" hydrodynamic"> hydrodynamic</a>, <a href="https://publications.waset.org/abstracts/search?q=instability" title=" instability"> instability</a>, <a href="https://publications.waset.org/abstracts/search?q=journal" title=" journal"> journal</a> </p> <a href="https://publications.waset.org/abstracts/36025/journal-bearing-with-controllable-radial-clearance-design-and-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36025.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">283</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> A Systematic Review of Efficacy and Safety of Radiofrequency Ablation in Patients with Spinal Metastases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pascale%20%20Brasseur">Pascale Brasseur</a>, <a href="https://publications.waset.org/abstracts/search?q=Binu%20%20Gurung"> Binu Gurung</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicholas%20%20Halfpenny"> Nicholas Halfpenny</a>, <a href="https://publications.waset.org/abstracts/search?q=James%20%20Eaton"> James Eaton</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Development of minimally invasive treatments in recent years provides a potential alternative to invasive surgical interventions which are of limited value to patients with spinal metastases due to short life expectancy. A systematic review was conducted to explore the efficacy and safety of radiofrequency ablation (RFA), a minimally invasive treatment in patients with spinal metastases. EMBASE, Medline and CENTRAL were searched from database inception to March 2017 for randomised controlled trials (RCTs) and non-randomised studies. Conference proceedings for ASCO and ESMO published in 2015 and 2016 were also searched. Fourteen studies were included: three prospective interventional studies, four prospective case series and seven retrospective case series. No RCTs or studies comparing RFA with another treatment were identified. RFA was followed by cement augmentation in all patients in seven studies and some patients (40-96%) in the remaining seven studies. Efficacy was assessed as pain relief in 13/14 studies with the use of a numerical rating scale (NRS) or a visual analogue scale (VAS) at various time points. Ten of the 13 studies reported a significant decrease in pain outcome, post-RFA compared to baseline. NRS scores improved significantly at 1 week (5.9 to 3.5, p < 0.0001; 8 to 4.3, p < 0.02 and 8 to 3.9, p < 0.0001) and this improvement was maintained at 1 month post-RFA compared to baseline (5.9 to 2.6, p < 0.0001; 8 to 2.9, p < 0.0003; 8 to 2.9, p < 0.0001). Similarly, VAS scores decreased significantly at 1 week (7.5 to 2.7, p=0.00005; 7.51 to 1.73, p < 0.0001; 7.82 to 2.82, p < 0.001) and this pattern was maintained at 1 month post-RFA compared to baseline (7.51 to 2.25, p < 0.0001; 7.82 to 3.3; p < 0.001). A significant pain relief was achieved regardless of whether patients had cement augmentation in two studies assessing the impact of RFA with or without cement augmentation on VAS pain scores. In these two studies, a significant decrease in pain scores was reported for patients receiving RFA alone and RFA+cement at 1 week (4.3 to 1.7. p=0.0004 and 6.6 to 1.7, p=0.003 respectively) and 15-36 months (7.9 to 4, p=0.008 and 7.6 to 3.5, p=0.005 respectively) after therapy. Few minor complications were reported and these included neural damage, radicular pain, vertebroplasty leakage and lower limb pain/numbness. In conclusion, the efficacy and safety of RFA were consistently positive between prospective and retrospective studies with reductions in pain and few procedural complications. However, the lack of control groups in the identified studies indicates the possibility of selection bias inherent in single arm studies. Controlled trials exploring efficacy and safety of RFA in patients with spinal metastases are warranted to provide robust evidence. The identified studies provide an initial foundation for such future trials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pain%20relief" title="pain relief">pain relief</a>, <a href="https://publications.waset.org/abstracts/search?q=radiofrequency%20ablation" title=" radiofrequency ablation"> radiofrequency ablation</a>, <a href="https://publications.waset.org/abstracts/search?q=spinal%20metastases" title=" spinal metastases"> spinal metastases</a>, <a href="https://publications.waset.org/abstracts/search?q=systematic%20review" title=" systematic review"> systematic review</a> </p> <a href="https://publications.waset.org/abstracts/77541/a-systematic-review-of-efficacy-and-safety-of-radiofrequency-ablation-in-patients-with-spinal-metastases" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77541.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">173</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> Human 3D Metastatic Melanoma Models for in vitro Evaluation of Targeted Therapy Efficiency</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Delphine%20Morales">Delphine Morales</a>, <a href="https://publications.waset.org/abstracts/search?q=Florian%20Lombart"> Florian Lombart</a>, <a href="https://publications.waset.org/abstracts/search?q=Agathe%20Truchot"> Agathe Truchot</a>, <a href="https://publications.waset.org/abstracts/search?q=Pauline%20Maire"> Pauline Maire</a>, <a href="https://publications.waset.org/abstracts/search?q=Pascale%20%20Vigneron"> Pascale Vigneron</a>, <a href="https://publications.waset.org/abstracts/search?q=Antoine%20Galmiche"> Antoine Galmiche</a>, <a href="https://publications.waset.org/abstracts/search?q=Catherine%20Lok"> Catherine Lok</a>, <a href="https://publications.waset.org/abstracts/search?q=Muriel%20Vayssade"> Muriel Vayssade</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Targeted therapy molecules are used as a first-line treatment for metastatic melanoma with B-Raf mutation. Nevertheless, these molecules can cause side effects to patients and are efficient on 50 to 60 % of them. Indeed, melanoma cell sensitivity to targeted therapy molecules is dependent on tumor microenvironment (cell-cell and cell-extracellular matrix interactions). To better unravel factors modulating cell sensitivity to B-Raf inhibitor, we have developed and compared several melanoma models: from metastatic melanoma cells cultured as monolayer (2D) to a co-culture in a 3D dermal equivalent. Cell response was studied in different melanoma cell lines such as SK-MEL-28 (mutant B-Raf (V600E), sensitive to Vemurafenib), SK-MEL-3 (mutant B-Raf (V600E), resistant to Vemurafenib) and a primary culture of dermal human fibroblasts (HDFn). Assays have initially been performed in a monolayer cell culture (2D), then a second time on a 3D dermal equivalent (dermal human fibroblasts embedded in a collagen gel). All cell lines were treated with Vemurafenib (a B-Raf inhibitor) for 48 hours at various concentrations. Cell sensitivity to treatment was assessed under various aspects: Cell proliferation (cell counting, EdU incorporation, MTS assay), MAPK signaling pathway analysis (Western-Blotting), Apoptosis (TUNEL), Cytokine release (IL-6, IL-1α, HGF, TGF-β, TNF-α) upon Vemurafenib treatment (ELISA) and histology for 3D models. In 2D configuration, the inhibitory effect of Vemurafenib on cell proliferation was confirmed on SK-MEL-28 cells (IC50=0.5 µM), and not on the SK-MEL-3 cell line. No apoptotic signal was detected in SK-MEL-28-treated cells, suggesting a cytostatic effect of the Vemurafenib rather than a cytotoxic one. The inhibition of SK-MEL-28 cell proliferation upon treatment was correlated with a strong expression decrease of phosphorylated proteins involved in the MAPK pathway (ERK, MEK, and AKT/PKB). Vemurafenib (from 5 µM to 10 µM) also slowed down HDFn proliferation, whatever cell culture configuration (monolayer or 3D dermal equivalent). SK-MEL-28 cells cultured in the dermal equivalent were still sensitive to high Vemurafenib concentrations. To better characterize all cell population impacts (melanoma cells, dermal fibroblasts) on Vemurafenib efficacy, cytokine release is being studied in 2D and 3D models. We have successfully developed and validated a relevant 3D model, mimicking cutaneous metastatic melanoma and tumor microenvironment. This 3D melanoma model will become more complex by adding a third cell population, keratinocytes, allowing us to characterize the epidermis influence on the melanoma cell sensitivity to Vemurafenib. In the long run, the establishment of more relevant 3D melanoma models with patients’ cells might be useful for personalized therapy development.

Numerous strategies are imperative, particularly emphasizing the reduction and optimization of energy demand. Ensuring the high energy performance of buildings emerges as a top priority, with measures aimed at cutting energy consumptions. Concurrently, it is imperative to decrease greenhouse gas emissions by using renewable energy sources for the on-site energy production, thereby striving for an energy balance leading towards zero-emission buildings. Italy's predominant building stock comprises ancient buildings, many of which hold historical significance and are subject to stringent preservation and conservation regulations. Attaining high levels of energy efficiency and reducing CO2 emissions in such buildings poses a considerable challenge, given their unique characteristics and the imperative to adhere to principles of conservation and restoration. Additionally, conducting a meticulous analysis of these buildings' current state is crucial for accurately quantifying their energy performance and predicting the potential impacts of proposed renovation strategies on energy consumption reduction. Within this framework, the paper presents a pilot case in Rome, outlining a methodological approach for the renovation of historic buildings towards achieving Zero Emission Building (ZEB) objective. The building has a mixed function with offices, a conference hall, and an exposition area. The building envelope is made of historical and precious materials used as cladding which must be preserved. A thorough understanding of the building's current condition serves as a prerequisite for analyzing its energy performance. This involves conducting comprehensive archival research, undertaking on-site diagnostic examinations to characterize the building envelope and its systems, and evaluating actual energy usage data derived from energy bills. Energy simulations and audit are the first step in the analysis with the assessment of the energy performance of the actual current state. Subsequently, different renovation scenarios are proposed, encompassing advanced building techniques, to pinpoint the key actions necessary for improving mechanical systems, automation and control systems, and the integration of renewable energy production. These scenarios entail different levels of renovation, ranging from meeting minimum energy performance goals to achieving the highest possible energy efficiency level. The proposed interventions are meticulously analyzed and compared to ascertain the feasibility of attaining the Zero Emission Building objective. In conclusion, the paper provides valuable insights that can be extrapolated to inform a broader approach towards energy-efficient refurbishment of historical buildings that may have limited potential for renovation in their building envelopes. By adopting a methodical and nuanced approach, it is possible to reconcile the imperative of preserving cultural heritage with the pressing need to transition towards a sustainable, low-carbon future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20conservation%20and%20transition" title="energy conservation and transition">energy conservation and transition</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency%20in%20historical%20buildings" title=" energy efficiency in historical buildings"> energy efficiency in historical buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=buildings%20energy%20performance" title=" buildings energy performance"> buildings energy performance</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20retrofitting" title=" energy retrofitting"> energy retrofitting</a>, <a href="https://publications.waset.org/abstracts/search?q=zero%20emission%20buildings" title=" zero emission buildings"> zero emission buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20simulation" title=" energy simulation"> energy simulation</a> </p> <a href="https://publications.waset.org/abstracts/183463/energy-audit-and-renovation-scenarios-for-a-historical-building-in-rome-a-pilot-case-towards-the-zero-emission-building-goal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183463.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">67</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> Bio-Functionalized Silk Nanofibers for Peripheral Nerve Regeneration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kayla%20Belanger">Kayla Belanger</a>, <a href="https://publications.waset.org/abstracts/search?q=Pascale%20Vigneron"> Pascale Vigneron</a>, <a href="https://publications.waset.org/abstracts/search?q=Guy%20Schlatter"> Guy Schlatter</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernard%20Devauchelle"> Bernard Devauchelle</a>, <a href="https://publications.waset.org/abstracts/search?q=Christophe%20Egles"> Christophe Egles</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A severe injury to a peripheral nerve leads to its degeneration and the loss of sensory and motor function. To this day, there still lacks a more effective alternative to the autograft which has long been considered the gold standard for nerve repair. In order to overcome the numerous drawbacks of the autograft, tissue engineered biomaterials may be effective alternatives. Silk fibroin is a favorable biomaterial due to its many advantageous properties such as its biocompatibility, its biodegradability, and its robust mechanical properties. In this study, bio-mimicking multi-channeled nerve guidance conduits made of aligned nanofibers achieved by electrospinning were functionalized with signaling biomolecules and were tested in vitro and in vivo for nerve regeneration support. Silk fibroin (SF) extracted directly from silkworm cocoons was put in solution at a concentration of 10wt%. Poly(ethylene oxide) (PEO) was added to the resulting SF solution to increase solution viscosity and the following three electrospinning solutions were made: (1) SF/PEO solution, (2) SF/PEO solution with nerve growth factor and ciliary neurotrophic factor, and (3) SF/PEO solution with nerve growth factor and neurotrophin-3. Each of these solutions was electrospun into a multi-layer architecture to obtain mechanically optimized aligned nanofibrous mats. For in vitro studies, aligned fibers were treated to induce β-sheet formation and thoroughly rinsed to eliminate presence of PEO. Each material was tested using rat embryo neuron cultures to evaluate neurite extension and the interaction with bio-functionalized or non-functionalized aligned fibers. For in vivo studies, the mats were rolled into 5mm long multi-, micro-channeled conduits then treated and thoroughly rinsed. The conduits were each subsequently implanted between a severed rat sciatic nerve. The effectiveness of nerve repair over a period of 8 months was extensively evaluated by cross-referencing electrophysiological, histological, and movement analysis results to comprehensively evaluate the progression of nerve repair. In vitro results show a more favorable interaction between growing neurons and bio-functionalized silk fibers compared to pure silk fibers. Neurites can also be seen having extended unidirectionally along the alignment of the nanofibers which confirms a guidance factor for the electrospun material. The in vivo study has produced positive results for the regeneration of the sciatic nerve over the length of the study, showing contrasts between the bio-functionalized material and the non-functionalized material along with comparisons to the experimental control. Nerve regeneration has been evaluated not only by histological analysis, but also by electrophysiological assessment and motion analysis of two separate natural movements. By studying these three components in parallel, the most comprehensive evaluation of nerve repair for the conduit designs can be made which can, therefore, more accurately depict their overall effectiveness.

The main symptoms concern eating (restriction, excessive food intake) and weight control behaviors (laxatives, vomiting). Psychological comorbidities (depression, executive function disorders, etc.) and problematic behaviors toward physical activity (PA) are commonly associated with ED. Acquaintances on ED risk factors are still lacking, and more community sample studies are needed to improve prevention and early detection. To our knowledge, studies are needed to specifically investigate the link between ED risk level, PA, and psychological risk factors in a community sample of adolescents. The aim of this study is to assess the relation between ED risk level, exercise (type, frequency, and motivations for engaging in exercise), and psychological factors based on the Jacobi risk factors model. We suppose that a high risk of ED will be associated with the practice of high caloric cost PA, motivations oriented to weight and shape control, and psychological disturbances. Method: An online survey destined for students has been sent to several middle schools and colleges in northwest France. This survey combined several questionnaires, the Eating Attitude Test-26 assessing ED risk; the Exercise Motivation Inventory–2 assessing motivations toward PA; the Hospital Anxiety and Depression Scale assessing anxiety and depression, the Contour Drawing Rating Scale; and the Body Esteem Scale assessing body dissatisfaction, Rosenberg Self-esteem Scale assessing self-esteem, the Exercise Dependence Scale-Revised assessing PA dependence, the Multidimensional Assessment of Interoceptive Awareness assessing interoceptive awareness and the Frost Multidimensional Perfectionism Scale assessing perfectionism. Machine learning analysis will be performed in order to constitute groups with a tree-based model clustering method, extract risk profile(s) with a bootstrap method comparison, and predict ED risk with a prediction method based on a decision tree-based model. Expected results: 1044 complete records have already been collected, and the survey will be closed at the end of May 2022. Records will be analyzed with a clustering method and a bootstrap method in order to reveal risk profile(s). Furthermore, a predictive tree decision method will be done to extract an accurate predictive model of ED risk. This analysis will confirm typical main risk factors and will give more data on presumed strong risk factors such as exercise motivations and interoceptive deficit. Furthermore, it will enlighten particular risk profiles with a strong level of proof and greatly contribute to improving the early detection of ED and contribute to a better understanding of ED risk factors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eating%20disorders" title="eating disorders">eating disorders</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factors" title=" risk factors"> risk factors</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20activity" title=" physical activity"> physical activity</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a> </p> <a href="https://publications.waset.org/abstracts/150235/machine-learning-analysis-of-eating-disorders-risk-physical-activity-and-psychological-factors-in-adolescents-a-community-sample-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150235.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">83</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> Health and Climate Changes: "Ippocrate" a New Alert System to Monitor and Identify High Risk</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Calabrese">A.

There is a vast literature demonstrating temperature increase is causally related to cardiovascular problem and represents a high risk for human health, but there are not study that improve a solution. In this work, it is studied how the clime influenced the human parameter through the analysis of climatic conditions in an area of the Apulia Region: Capurso Municipality. At the same time, medical personnel involved identified a set of variables useful to define an index describing health condition. These scientific studies are the base of an innovative alert system, IPPOCRATE, whose aim is to asses climate risk and share information to population at risk to support prevention and mitigation actions. IPPOCRATE is an e-health system, it is designed to provide technological support to analysis of health risk related to climate and provide tools for prevention and management of critical events. It is the first integrated system of prevention of human risk caused by climate change. IPPOCRATE calculates risk weighting meteorological data with the vulnerability of monitored subjects and uses mobile and cloud technologies to acquire and share information on different data channels. It is composed of four components: Multichannel Hub. Multichannel Hub is the ICT infrastructure used to feed IPPOCRATE cloud with a different type of data coming from remote monitoring devices, or imported from meteorological databases. Such data are ingested, transformed and elaborated in order to be dispatched towards mobile app and VoIP phone systems. IPPOCRATE Multichannel Hub uses open communication protocols to create a set of APIs useful to interface IPPOCRATE with 3rd party applications. Internally, it uses non-relational paradigm to create flexible and highly scalable database. WeHeart and Smart Application The wearable device WeHeart is equipped with sensors designed to measure following biometric variables: heart rate, systolic blood pressure and diastolic blood pressure, blood oxygen saturation, body temperature and blood glucose for diabetic subjects. WeHeart is designed to be easy of use and non-invasive. For data acquisition, users need only to wear it and connect it to Smart Application by Bluetooth protocol. Easy Box was designed to take advantage from new technologies related to e-health care. EasyBox allows user to fully exploit all IPPOCRATE features. Its name, Easy Box, reveals its purpose of container for various devices that may be included depending on user needs. Territorial Registry is the IPPOCRATE web module reserved to medical personnel for monitoring, research and analysis activities. Territorial Registry allows to access to all information gathered by IPPOCRATE using GIS system in order to execute spatial analysis combining geographical data (climatological information and monitored data) with information regarding the clinical history of users and their personal details. Territorial Registry was designed for different type of users: control rooms managed by wide area health facilities, single health care center or single doctor. Territorial registry manages such hierarchy diversifying the access to system functionalities. IPPOCRATE is the first e-Health system focused on climate risk prevention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20risk" title=" health risk"> health risk</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20technological%20system" title=" new technological system"> new technological system</a> </p> <a href="https://publications.waset.org/abstracts/28782/health-and-climate-changes-ippocrate-a-new-alert-system-to-monitor-and-identify-high-risk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28782.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">867</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> Understanding Stock-Out of Pharmaceuticals in Timor-Leste: A Case Study in Identifying Factors Impacting on Pharmaceutical Quantification in Timor-Leste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lourenco%20Camnahas">Lourenco Camnahas</a>, <a href="https://publications.waset.org/abstracts/search?q=Eileen%20Willis"> Eileen Willis</a>, <a href="https://publications.waset.org/abstracts/search?q=Greg%20Fisher"> Greg Fisher</a>, <a href="https://publications.waset.org/abstracts/search?q=Jessie%20Gunson"> Jessie Gunson</a>, <a href="https://publications.waset.org/abstracts/search?q=Pascale%20Dettwiller"> Pascale Dettwiller</a>, <a href="https://publications.waset.org/abstracts/search?q=Charlene%20Thornton"> Charlene Thornton</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Stock-out of pharmaceuticals is a common issue at all level of health services in Timor-Leste, a small post-conflict country. This lead to the research questions: what are the current methods used to quantify pharmaceutical supplies; what factors contribute to the on-going pharmaceutical stock-out? The study examined factors that influence the pharmaceutical supply chain system. Methodology: Privett and Goncalvez dependency model has been adopted for the design of the qualitative interviews. The model examines pharmaceutical supply chain management at three management levels: management of individual pharmaceutical items, health facilities, and health systems. The interviews were conducted in order to collect information on inventory management, logistics management information system (LMIS) and the provision of pharmaceuticals. Andersen' behavioural model for healthcare utilization also informed the interview schedule, specifically factors linked to environment (healthcare system and external environment) and the population (enabling factors). Forty health professionals (bureaucrats, clinicians) and six senior officers from a United Nations Agency, a global multilateral agency and a local non-governmental organization were interviewed on their perceptions of factors (healthcare system/supply chain and wider environment) impacting on stock out. Additionally, policy documents for the entire healthcare system, along with population data were collected. Findings: An analysis using Pozzebon’s critical interpretation identified a range of difficulties within the system from poor coordination to failure to adhere to policy guidelines along with major difficulties with inventory management, quantification, forecasting, and budgetary constraints. Weak logistics management information system, lack of capacity in inventory management, monitoring and supervision are additional organizational factors that also contributed to the issue. There were various methods of quantification of pharmaceuticals applied in the government sector, and non-governmental organizations. Lack of reliable data is one of the major problems in the pharmaceutical provision. Global Fund has the best quantification methods fed by consumption data and malaria cases. There are other issues that worsen stock-out: political intervention, work ethic and basic infrastructure such as unreliable internet connectivity. Major issues impacting on pharmaceutical quantification have been identified. However, current data collection identified limitations within the Andersen model; specifically, a failure to take account of predictors in the healthcare system and the environment (culture/politics/social. The next step is to (a) compare models used by three non-governmental agencies with the government model; (b) to run the Andersen explanatory model for pharmaceutical expenditure for 2 to 5 drug items used by these three development partners in order to see how it correlates with the present model in terms of quantification and forecasting the needs; (c) to repeat objectives (a) and (b) using the government model; (d) to draw a conclusion about the strength. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inventory%20management"
