The natural dyes are friendly to human health and environment. Cochineal (Dactylopius coccus Costa) can be used with other natural dye plants for colouration of silk and wool fabrics. Almost never research works on the dyeing of silk fabric with Dactylopius coccus Costa and Quercus infectoria Olivier together. In this study, dyeability of 100 % silk fabric with Dactylopius coccus Costa and Quercus infectoria Olivier was studied. Optimum dyeing parameters were determined by using different concentration of Dactylopius coccus Costa (10%), Quercus infectoria Olivier (0,1,5 and 10%) and mordant salt (0 and 3%). The dyed silk fabrics were examined for their colorimetric and fastness properties. The fabrics were dyed succesfully dark colours with 10 % Dactylopius coccus Costa, 10 % Quercus infectoria Olivier and presence of mordanting after dyeing process (3% mordant salt). The washing and light colour fastness of the dyed fabrics were investigated and adequate results were obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dactylopius%20coccus%20Costa" title="Dactylopius coccus Costa">Dactylopius coccus Costa</a>, <a href="https://publications.waset.org/abstracts/search?q=Quercus%20infectoria%20Olivier" title=" Quercus infectoria Olivier"> Quercus infectoria Olivier</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20dye" title=" natural dye"> natural dye</a>, <a href="https://publications.waset.org/abstracts/search?q=dyeing" title=" dyeing"> dyeing</a>, <a href="https://publications.waset.org/abstracts/search?q=silk%20fabric" title=" silk fabric"> silk fabric</a> </p> <a href="https://publications.waset.org/abstracts/25583/dyeability-of-silk-fabric-with-dactylopius-coccus-costa-and-quercus-infectoria-olivier" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25583.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">597</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">83</span> Ecobiological Study of Olivier in the Northern Slopes of the Mountains of Tlemcen, Western Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hachemi%20Nouria">Hachemi Nouria</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The olive tree is a Mediterranean tree, which belongs to the family Oleaceae. The Olea genus contains various species and subspecies, and the only species bearing edible fruit is Olea europaea. The desired issue in this study is to provide the current status of plant cover and especially the training in Olea europaea currently existing in the major centers of the region of Tlemcen. While based on the flora and biometric aspect of this plant germplasm. In order to make an assessment of the phytomass, we made measurements of the four parameters of the aerial part of the taxon: height, diameter, and canopy density to ten feet of the olive tree per station. The floristic analysis shows a certain floristic difference between the different stations. The vegetal formations reflect the biotic and abiotic conditions including climate affecting the ecosystem. Biometric study on the feet of Olea in the six study sites, has led us to conclude that the four measured parameters provides insight on the development or degradation of Olea feet depending on the layout of the stations and the factors environmental. We find that the terrains are havens for these assets. Also the local microclimate (Oued Thalweg) promotes the healthy development of this species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=olivier" title="olivier">olivier</a>, <a href="https://publications.waset.org/abstracts/search?q=ecology" title=" ecology"> ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=biometrics" title=" biometrics"> biometrics</a>, <a href="https://publications.waset.org/abstracts/search?q=Tlemcen" title=" Tlemcen"> Tlemcen</a>, <a href="https://publications.waset.org/abstracts/search?q=Algeria" title=" Algeria"> Algeria</a> </p> <a href="https://publications.waset.org/abstracts/29444/ecobiological-study-of-olivier-in-the-northern-slopes-of-the-mountains-of-tlemcen-western-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29444.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">296</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">82</span> Randomized Controlled Trial for the Management of Pain and Anxiety Using Virtual Reality During the Care of Older Hospitalized Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Corbel%20Camille">Corbel Camille</a>, <a href="https://publications.waset.org/abstracts/search?q=Le%20Cerf%20Flora"> Le Cerf Flora</a>, <a href="https://publications.waset.org/abstracts/search?q=Capriz%20Fran%C3%A7oise"> Capriz Françoise</a>, <a href="https://publications.waset.org/abstracts/search?q=Vaillant-Ciszewicz%20Anne-Julie"> Vaillant-Ciszewicz Anne-Julie</a>, <a href="https://publications.waset.org/abstracts/search?q=Breaud%20Jean"> Breaud Jean</a>, <a href="https://publications.waset.org/abstracts/search?q=Guerin%20Olivier"> Guerin Olivier</a>, <a href="https://publications.waset.org/abstracts/search?q=Corveleyn%20Xavier"> Corveleyn Xavier</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: The medical environment can generate stressful and anxiety-provoking situations for patients, particularly during painful care procedures for the older population. These stressful environments have deleterious effects on the quality of care and can even put the patient at risk and set the care team up for failure. The search for a solution is, therefore, imperative. The development of new technologies, such as virtual reality (VR), seems to be an answer to this problem. Objectives: The objective of this study is to compare the effects of virtual reality on pain and anxiety when caring for older hospitalized people with the effects of usual care. More precisely, different individual factors (age, cognitive level, individual preferences, etc.) and different virtual reality universes (personalized or non-personalized) are studied to understand the role of these factors in reducing pain and anxiety during care procedures. The aim of this study is to improve the quality of life of patients and caregivers in their work environment. Method: This mono-centered, randomized, controlled study was conducted from September 2023 to September 2024 on 120 participants recruited from the geriatric departments of the Cimiez Hospital, Nice, France. Participants are randomized into three groups: a control group, a personalized VR group and a non-personalized VR group. Each participant is followed during a painful care session. Data are collected before, during and after the care, using measures of pain (Algoplus and numerical scale) and anxiety (Hospital anxiety scale and numerical scale). Physiological assessments with an oximeter are also performed to collect both heart and respiratory rate measurements. The implementation of the care will be assessed among healthcare providers to evaluate its effects on the difficulty and fatigue associated with the care. Additionally, a questionnaire (System Usability Scale) will be administered at the conclusion of the study to determine the willingness of healthcare providers to integrate VR into their daily care practices. Result: The preliminary results indicate significant effects on anxiety (p=.001) and pain (p=<.001) following the VR intervention during care, as compared to the control group. Conclusion: The preliminary results suggest that VRI appears to be a suitable and effective method for reducing anxiety and pain among older hospitalized individuals compared with standard care. Finally, the experiences of healthcare professionals involved will also be considered to assess the impact of these interventions on working conditions and patient support. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anxiety" title="anxiety">anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=care" title=" care"> care</a>, <a href="https://publications.waset.org/abstracts/search?q=pain" title=" pain"> pain</a>, <a href="https://publications.waset.org/abstracts/search?q=older%20adults" title=" older adults"> older adults</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20reality" title=" virtual reality"> virtual reality</a> </p> <a href="https://publications.waset.org/abstracts/179162/randomized-controlled-trial-for-the-management-of-pain-and-anxiety-using-virtual-reality-during-the-care-of-older-hospitalized-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179162.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">73</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">81</span> Melanoma Antigen Proteins Are Involved in DNA Damage Response</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olivier%20de%20Backer">Olivier de Backer</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexis%20Khelfi"> Alexis Khelfi</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Svensek"> Olivier Svensek</a>, <a href="https://publications.waset.org/abstracts/search?q=Axelle%20Nolmans"> Axelle Nolmans</a>, <a href="https://publications.waset.org/abstracts/search?q=Dominique%20Desnoeck"> Dominique Desnoeck</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The SMC5-SMC6 complex helps replication and repair of DNA double-strand breaks. Nse1, Nse3 and Nse4 are non-SMC components of the complex in which Nse3 stimulates the E3 ubiquitin ligase activity of Nse1 and is required for recruiting the complex on DNA. In most eukaryotes, Nse3 is a single protein, but in eutherians (placental mammals), it belongs to a large family of proteins called MAGE (Melanoma antigen) that share a conserved domain of about 200 aa known as MHD (Mage homology domain). MAGE assembles specific RING and HECT ubiquitin ligases and determines new substrates for ubiquitination. The MHD is required for the interaction with the cognate E3 ligase. Some MAGEs (referred to as Type I) are exclusively expressed in germ cells of the testis but are often expressed ectopically in cancer cells as the result of epigenetic modifications. The 12 MAGE-A genes belong to this category. Serval MAGE-A proteins could promote tumorigenesis by targeting tumor suppressor proteins (including p53) for ubiquitination and degradation. We showed that depletion of MAGE-A proteins in melanoma cells results in impaired DNA damage response and increased double-strand breaks after exposure to camptothecin. Moreover, it was shown that other actors of the DNA Damage Response were impacted when cells were depleted of MAGEA proteins. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DNA%20damage%20response" title="DNA damage response">DNA damage response</a>, <a href="https://publications.waset.org/abstracts/search?q=melanoma" title=" melanoma"> melanoma</a>, <a href="https://publications.waset.org/abstracts/search?q=camptothecin" title=" camptothecin"> camptothecin</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20role" title=" new role"> new role</a>, <a href="https://publications.waset.org/abstracts/search?q=MAGEA" title=" MAGEA"> MAGEA</a> </p> <a href="https://publications.waset.org/abstracts/169692/melanoma-antigen-proteins-are-involved-in-dna-damage-response" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169692.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">101</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">80</span> Sublethal Effects of Entomopathogenic Nematodes and Fungus against the Red Palm Weevil, Rhynchophorus Ferrugineus (Olivier) (Curculionidae: Coleoptera)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Manzoor">M.

Haider</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The invasive Red Palm Weevil (RPW) (Rhynchophorus ferrugineus [Olivier] (Coleoptera: Curculionidae) is one of the most destructive palm pests in the world. Synthetic pesticides are environmentally hazardous pest control strategies being used in the past with emerging need of eco-friendly biological approaches including microbial entomopathogens for RPW management. The sublethal effects of a single entomopathogenic fungus (EPF) Beauveria bassiana (WG-11) (Ascomycota: Hypocreales) and two entomopathogenic nematode (EPN) species Heterorhabditis bacteriophora (Poinar) and Steinernema carpocapsae (Weiser) (Nematoda: Rhabditida) were evaluated in various combinations against laboratory-reared 3rd, 5th and 8th instar larvae of RPW in laboratory assays. Individual and combined effects of both entomopathogens (EP) were observed after the pre-application of B. bassiana fungus at 1-2-week intervals. A number of parameters were measured after the application of sub-lethal doses of EPF such as diet consumption, development, frass production, mortality, and weight gain. Combined treatments were tested for additive and synergistic effects. Synergism was more frequently observed in B. bassiana and S. carpocapsae combined treatments than in B. bassiana and H. bacteriophora combinations. Early instar larvae of RPW were more susceptible than older instars. Synergistic effects were observed in the 3rd and 5th instars exposed to B. bassiana and S. carpocapsae at 0, 7 and 14-day intervals. Whereas, in 8th instar larvae, the synergistic effect was observed only in B. bassiana and S. carpocapsae treatments after 0 and 7 days intervals. EPN treatments decreased pupation, egg hatching and emergence of adults. Lethal effects of nematodes were also observed in all growth stages of R. ferrugineus. Reduced larval weight, increased larval, pre-pupal and pupal duration, reduced adult weight and life span were observed. Sub-lethal concentrations of both entomopathogens induced variations in the different developmental stages and reduced food consumption, frass production, growth, and weight gain. So, on the basis of results, it is concluded that synthetic pesticides should be replaced with environmentally friendly sustainable biopesticides. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20bacteriophora" title="H. bacteriophora">H. bacteriophora</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20carpocapsae" title=" S. carpocapsae"> S. carpocapsae</a>, <a href="https://publications.waset.org/abstracts/search?q=B.%20bassiana" title=" B. bassiana"> B. bassiana</a>, <a href="https://publications.waset.org/abstracts/search?q=mortality" title=" mortality"> mortality</a> </p> <a href="https://publications.waset.org/abstracts/108739/sublethal-effects-of-entomopathogenic-nematodes-and-fungus-against-the-red-palm-weevil-rhynchophorus-ferrugineus-olivier-curculionidae-coleoptera" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108739.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">169</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">79</span> VaR or TCE: Explaining the Preferences of Regulators</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Faroni">Silvia Faroni</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Le%20Courtois"> Olivier Le Courtois</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Ostaszewski"> Krzysztof Ostaszewski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> While a lot of research concentrates on the merits of VaR and TCE, which are the two most classic risk indicators used by financial institutions, little has been written on explaining why regulators favor the choice of VaR or TCE in their set of rules.

Further, this paper provides equivalence rules that explain how a given choice of VaR can be equivalent to a given choice of TCE.

Firstly, the existing high-resolution digital camera with special design of overlap images is designed by reconstructing and analyzing the auto-flying paths of UAVs, which improves the self-calibration function to achieve the high precision imaging by software, and further increased the resolution of the imaging system. Secondly, several-angle images including vertical images and oblique images gotten by the UAV system are used for the detail measure of urban land surfaces and the texture extraction. Finally, the aerial photography and 3D topography construction are both developed in campus of Chang-Jung University and in Guerin district area in Tainan, Taiwan, provide authentication model for construction of 3D topography based on combined UAV-based camera images from system. The results demonstrated that the UAV system for low altitude aerial photogrammetry can be used in the construction of 3D topography production, and the technology solution in this paper offers a new, fast, and technical plan for the 3D expression of the city landscape, fine modeling and visualization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D" title="3D">3D</a>, <a href="https://publications.waset.org/abstracts/search?q=topography" title=" topography"> topography</a>, <a href="https://publications.waset.org/abstracts/search?q=UAV" title=" UAV"> UAV</a>, <a href="https://publications.waset.org/abstracts/search?q=images" title=" images"> images</a> </p> <a href="https://publications.waset.org/abstracts/82548/study-on-construction-of-3d-topography-by-uav-based-images" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82548.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">304</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">77</span> Delay-Independent Closed-Loop Stabilization of Neutral System with Infinite Delays</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iyai%20Davies">Iyai Davies</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20L.%20C.%20Haas"> Olivier L.

However, very few studies have identified the underlying demographic processes. For short-lived species, like common passerine birds, are these changes generated by changes in adult survival or in fecundity and recruitment? This study tests for an effect of annual climatic conditions (spring and winter) on annual, local adult survival at very large spatial (a country, 252 sites), temporal (25 years) and biological (25 species) scales. The Constant Effort Site ringing has allowed the collection of capture - mark - recapture data for 100 000 adult individuals since 1989, over metropolitan France, thus documenting annual, local survival rates of the most common passerine birds. We specifically developed a set of multi-year, multi-species, multi-site Bayesian models describing variations in local survival and recapture probabilities. This method allows for a statistically powerful hierarchical assessment (global versus species-specific) of the effects of climate variables on survival. A major part of between-year variations in survival rate was common to all species (74% of between-year variance), whereas only 26% of temporal variation was species-specific. Although changing spring climate is commonly invoked as a cause of population size fluctuations, spring climatic anomalies (mean precipitation or temperature for March-August) do not impact adult survival: only 1% of between-year variation of species survival is explained by spring climatic anomalies. However, for sedentary birds, winter climatic anomalies (North Atlantic Oscillation) had a significant, quadratic effect on adult survival, birds surviving less during intermediate years than during more extreme years. For migratory birds, we do not detect an effect of winter climatic anomalies (Sahel Rainfall). We will analyze the life history traits (migration, habitat, thermal range) that could explain a different sensitivity of species to winter climate anomalies. Overall, we conclude that changes in population sizes for passerine birds are unlikely to be the consequences of climate-driven mortality (or emigration) in spring but could be induced by other demographic parameters, like fecundity. <p class="card-text"><strong>Keywords:</strong> <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=capture-recapture" title=" capture-recapture"> capture-recapture</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20anomaly" title=" climate anomaly"> climate anomaly</a>, <a href="https://publications.waset.org/abstracts/search?q=constant%20effort%20sites%20scheme" title=" constant effort sites scheme"> constant effort sites scheme</a>, <a href="https://publications.waset.org/abstracts/search?q=passerine" title=" passerine"> passerine</a>, <a href="https://publications.waset.org/abstracts/search?q=seasons" title=" seasons"> seasons</a>, <a href="https://publications.waset.org/abstracts/search?q=survival" title=" survival"> survival</a> </p> <a href="https://publications.waset.org/abstracts/42791/winter-not-spring-climate-drives-annual-adult-survival-in-common-passerines-a-country-wide-multi-species-modeling-exercise" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42791.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">303</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">75</span> Direct Measurement of Pressure and Temperature Variations During High-Speed Friction Experiments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Simon%20Guerin-Marthe">Simon Guerin-Marthe</a>, <a href="https://publications.waset.org/abstracts/search?q=Marie%20Violay"> Marie Violay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Thermal Pressurization (TP) has been proposed as a key mechanism involved in the weakening of faults during dynamic ruptures. Theoretical and numerical studies clearly show how frictional heating can lead to an increase in pore fluid pressure due to the rapid slip along faults occurring during earthquakes. In addition, recent laboratory studies have evidenced local pore pressure or local temperature variation during rotary shear tests, which are consistent with TP theoretical and numerical models. The aim of this study is to complement previous ones by measuring both local pore pressure and local temperature variations in the vicinity of a water-saturated calcite gouge layer subjected to a controlled slip velocity in direct double shear configuration. Laboratory investigation of TP process is crucial in order to understand the conditions at which it is likely to become a dominant mechanism controlling dynamic friction. It is also important in order to understand the timing and magnitude of temperature and pore pressure variations, to help understanding when it is negligible, and how it competes with other rather strengthening-mechanisms such as dilatancy, which can occur during rock failure. Here we present unique direct measurements of temperature and pressure variations during high-speed friction experiments under various load point velocities and show the timing of these variations relatively to the slip event. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermal%20pressurization" title="thermal pressurization">thermal pressurization</a>, <a href="https://publications.waset.org/abstracts/search?q=double-shear%20test" title=" double-shear test"> double-shear test</a>, <a href="https://publications.waset.org/abstracts/search?q=high-speed%20friction" title=" high-speed friction"> high-speed friction</a>, <a href="https://publications.waset.org/abstracts/search?q=dilatancy" title=" dilatancy"> dilatancy</a> </p> <a href="https://publications.waset.org/abstracts/170630/direct-measurement-of-pressure-and-temperature-variations-during-high-speed-friction-experiments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170630.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">63</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">74</span> Modified Preputial Urethrostomy as a Salvage Procedure in Four Dogs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Giansetto">Thomas Giansetto</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Broux"> Olivier Broux</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%A9raldine%20Bolen"> Géraldine Bolen</a>, <a href="https://publications.waset.org/abstracts/search?q=St%C3%A9phanie%20Claeys"> Stéphanie Claeys</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: To describe a modified preputial urethrostomy in four dogs.

We show here that the large size and low charge density of POMs, compared to classical ions, are responsible for a peculiar behavior called “super-chaotropy”. This property refers to the strong propensity of nano-ions to adsorb at neutral polar interfaces, via non-specific interactions. It has strong effects on phase transitions in soft matter and can, for example, stabilize colloidal systems such as surfactant foams. A simple way for evaluating and classifying nano-ions, such as POMs, according to their super-chaotropy is proposed here. The super-chaotropic behavior of nano-ions opens many opportunities in separation science, catalysis, and for the design of nanostructured hybrid materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=colloids" title="colloids">colloids</a>, <a href="https://publications.waset.org/abstracts/search?q=foams" title=" foams"> foams</a>, <a href="https://publications.waset.org/abstracts/search?q=surfactant" title=" surfactant"> surfactant</a>, <a href="https://publications.waset.org/abstracts/search?q=salt%20effect" title=" salt effect"> salt effect</a>, <a href="https://publications.waset.org/abstracts/search?q=colloidal%20stability" title=" colloidal stability"> colloidal stability</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-ions" title=" nano-ions"> nano-ions</a> </p> <a href="https://publications.waset.org/abstracts/172708/nanometric-sized-ions-for-colloidal-stabilization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172708.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">74</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">72</span> Impact of Network Workload between Virtualization Solutions on a Testbed Environment for Cybersecurity Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kevin%20Fernagut">Kevin Fernagut</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Flauzac"> Olivier Flauzac</a>, <a href="https://publications.waset.org/abstracts/search?q=Erick%20M.%20G.%20Robledo"> Erick M.

This paper seeks to assess this with a different approach studying the behavior of a testbed built with tools such as Kernel-Based Virtual Machine (KVM), Linux Containers (LXC) and Docker, by performing stress tests within a platform where students experiment simultaneously with cyber-attacks, and thus observe the impact on the campus network and also find the best solution for cyber-security learning. Interesting outcomes can be found in the literature comparing these technologies. It is, however, difficult to find results of the effects on the global network where experiments are carried out. Our work shows that other physical hosts and the faculty network were impacted while performing these trials. The problems found are discussed, as well as security solutions and the adoption of new network policies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=containerization" title="containerization">containerization</a>, <a href="https://publications.waset.org/abstracts/search?q=containers" title=" containers"> containers</a>, <a href="https://publications.waset.org/abstracts/search?q=cybersecurity" title=" cybersecurity"> cybersecurity</a>, <a href="https://publications.waset.org/abstracts/search?q=cyberattacks" title=" cyberattacks"> cyberattacks</a>, <a href="https://publications.waset.org/abstracts/search?q=isolation" title=" isolation"> isolation</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=virtualization" title=" virtualization"> virtualization</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20machines" title=" virtual machines"> virtual machines</a> </p> <a href="https://publications.waset.org/abstracts/127012/impact-of-network-workload-between-virtualization-solutions-on-a-testbed-environment-for-cybersecurity-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127012.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">150</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">71</span> 2D RF ICP Torch Modelling with Fluid Plasma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mokhtar%20Labiod">Mokhtar Labiod</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabil%20Ikhlef"> Nabil Ikhlef</a>, <a href="https://publications.waset.org/abstracts/search?q=Keltoum%20Bouherine"> Keltoum Bouherine</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Leroy"> Olivier Leroy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A numerical model for the radio-frequency (RF) Argon discharge chamber is developed to simulate the low pressure low temperature inductively coupled plasma.

However, when tested for cellular immune responses using peripheral blood mononuclear cells from tuberculosis patients and <em>BCG</em>-vaccinated healthy subjects, this protein was found to be a major stimulator of cell mediated immune responses in both groups of subjects. In order to further identify the sequence of immunodominant epitopes and explore their Human Leukocyte Antigen (HLA)-restriction for epitope recognition, 24 peptides (25-mers overlapping with the neighboring peptides by 10 residues) covering the sequence of Rv3873 were synthesized chemically using fluorenylmethyloxycarbonyl chemistry and tested in cell mediated immune responses. The results of these experiments helped in the identification of an immunodominant peptide P9 that was recognized by people expressing varying HLA-DR types. Furthermore, it was also predicted to be a promiscuous binder with multiple epitopes for binding to HLA-DR, HLA-DP and HLA-DQ alleles of HLA-class II molecules that present antigens to T helper cells, and to HLA-class I molecules that present antigens to T cytotoxic cells. In addition, the evaluation of peptide P9 using an immunogenicity predictor server yielded a high score (0.94), which indicated a greater probability of this peptide to elicit a protective cellular immune response. In conclusion, P9, a peptide with multiple epitopes and ability to bind several HLA class I and class II molecules for presentation to cells of the cellular immune response, may be useful as a peptide-based vaccine against tuberculosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mycobacterium%20tuberculosis" title="mycobacterium tuberculosis">mycobacterium tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=PPE68" title=" PPE68"> PPE68</a>, <a href="https://publications.waset.org/abstracts/search?q=peptides" title=" peptides"> peptides</a>, <a href="https://publications.waset.org/abstracts/search?q=vaccine" title=" vaccine"> vaccine</a> </p> <a href="https://publications.waset.org/abstracts/82250/identification-of-promiscuous-epitopes-for-cellular-immune-responses-in-the-major-antigenic-protein-rv3873-encoded-by-region-of-difference-1-of-mycobacterium-tuberculosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82250.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">135</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">68</span> Heat Transfer Enhancement by Localized Time Varying Thermal Perturbations at Hot and Cold Walls in a Rectangular Differentially Heated Cavity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Thiers">Nicolas Thiers</a>, <a href="https://publications.waset.org/abstracts/search?q=Romain%20Gers"> Romain Gers</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Skurtys"> Olivier Skurtys</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, we study numerically the effect of a thermal perturbation on the heat transfer in a rectangular differentially heated cavity of aspect ratio 4, filled by air.

The results show that the perturbation has a major impact for the highest amplitude, and at about three quarters of the cavity height, upstream, in both hot and cold boundary layers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=direct%20numerical%20simulation" title="direct numerical simulation">direct numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer%20enhancement" title=" heat transfer enhancement"> heat transfer enhancement</a>, <a href="https://publications.waset.org/abstracts/search?q=localized%20thermal%20perturbations" title=" localized thermal perturbations"> localized thermal perturbations</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20convection" title=" natural convection"> natural convection</a>, <a href="https://publications.waset.org/abstracts/search?q=rectangular%20differentially-heated%20cavity" title=" rectangular differentially-heated cavity"> rectangular differentially-heated cavity</a> </p> <a href="https://publications.waset.org/abstracts/109171/heat-transfer-enhancement-by-localized-time-varying-thermal-perturbations-at-hot-and-cold-walls-in-a-rectangular-differentially-heated-cavity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109171.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">67</span> Achievements of Healthcare Services Vis-À-Vis the Millennium Development Goals Targets: Evidence from Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeeda%20Batool">Saeeda Batool</a>, <a href="https://publications.waset.org/abstracts/search?q=Ather%20Maqsood%20Ahmed"> Ather Maqsood Ahmed </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigates the impact of public healthcare facilities and socio-economic circumstances on the status of child health in Pakistan. The complete analysis is carried out in correspondence with fourth and sixth millennium development goals. Further, the health variables chosen are also inherited from targeted indicators of the mentioned goals (MDGs). Trends in the Human Opportunity Index (HOI) for both health inequalities and coverage are analyzed using the Pakistan Social and Living Standards Measurement (PLSM) data set for 2001-02 to 2012-13 at the national and provincial level. To reveal the relative importance of each circumstance in achieving the targeted values for child health, Shorrocks decomposition is applied on HOI. The annual point average growth rate of HOI is used to simulate the time period for the achievement of target set by MDGs and universal access also. The results indicate an improvement in HOI for a reduction in child mortality rates from 52.1% in 2001-02 to 67.3% in 2012-13, which confirms the availability of healthcare opportunities to a larger segment of society. Similarly, immunization against measles and other diseases such as Diphtheria, Polio, Bacillus Calmette-Guerin (BCG), and Hepatitis has also registered an improvement from 51.6% to 69.9% during the period of study at the national level. On a positive note, no gender disparity has been found for child health indicators and that health outcome is mostly affected by the parental and geographical features and availability of health infrastructure. However, the study finds that this achievement has been uneven across provinces. Pakistan is not only lagging behind in achieving its health goals, disappointingly with the current rate of health care provision, but it will take many additional years to achieve its targets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=socio-economic%20circumstances" title="socio-economic circumstances">socio-economic circumstances</a>, <a href="https://publications.waset.org/abstracts/search?q=unmet%20MDGs" title=" unmet MDGs"> unmet MDGs</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20healthcare%20services" title=" public healthcare services"> public healthcare services</a>, <a href="https://publications.waset.org/abstracts/search?q=child%20and%20infant%20mortality" title=" child and infant mortality"> child and infant mortality</a> </p> <a href="https://publications.waset.org/abstracts/70678/achievements-of-healthcare-services-vis-a-vis-the-millennium-development-goals-targets-evidence-from-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70678.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">229</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">66</span> An Interpolation Tool for Data Transfer in Two-Dimensional Ice Accretion Problems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marta%20Cordero-Gracia">Marta Cordero-Gracia</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariola%20Gomez"> Mariola Gomez</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Blesbois"> Olivier Blesbois</a>, <a href="https://publications.waset.org/abstracts/search?q=Marina%20Carrion"> Marina Carrion</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the difficulties in icing simulations is for extended periods of exposure, when very large ice shapes are created. As well as being large, they can have complex shapes, such as a double horn. For icing simulations, these configurations are currently computed in several steps. The icing step is stopped when the ice shapes become too large, at which point a new mesh has to be created to allow for further CFD and ice growth simulations to be performed. This can be very costly, and is a limiting factor in the simulations that can be performed. A way to avoid the costly human intervention in the re-meshing step of multistep icing computation is to use mesh deformation instead of re-meshing. The aim of the present work is to apply an interpolation method based on Radial Basis Functions (RBF) to transfer deformations from surface mesh to volume mesh. This deformation tool has been developed specifically for icing problems. It is able to deal with localized, sharp and large deformations, unlike the tools traditionally used for more smooth wing deformations. This tool will be presented along with validation on typical two-dimensional icing shapes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ice%20accretion" title="ice accretion">ice accretion</a>, <a href="https://publications.waset.org/abstracts/search?q=interpolation" title=" interpolation"> interpolation</a>, <a href="https://publications.waset.org/abstracts/search?q=mesh%20deformation" title=" mesh deformation"> mesh deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20basis%20functions" title=" radial basis functions"> radial basis functions</a> </p> <a href="https://publications.waset.org/abstracts/59130/an-interpolation-tool-for-data-transfer-in-two-dimensional-ice-accretion-problems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59130.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">313</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">65</span> Analytical Approach to Study the Uncertainties Related to the Behavior of Structures Submitted to Differential Settlement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elio%20El%20Kahi">Elio El Kahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Michel%20Khouri"> Michel Khouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Deck"> Olivier Deck</a>, <a href="https://publications.waset.org/abstracts/search?q=Pierre%20Rahme"> Pierre Rahme</a>, <a href="https://publications.waset.org/abstracts/search?q=Rasool%20Mehdizadeh"> Rasool Mehdizadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recent developments in civil engineering create multiple interaction problems between the soil and the structure.

The main purpose of this research is to study the behavior of structures submitted to differential settlement, in order to assess their vulnerability, taking into consideration the different sources of uncertainties. Analytical approach is applied to investigate on one hand the influence of these uncertainties that are related to the soil, and on the other hand the structure stiffness variation with the presence of openings and the movement transmitted between them as related to the origin and shape of the free-field movement.

This awareness has prompted the development of new products more environmentally friendly. Among these products are biocomposite materials reinforced with natural fibers. The main challenge in developing the use of biocomposites in exterior applications is the lack of knowledge about their durability and the evolution of their mechanical and physico-chemical properties in the long term. Few studies have been carried out on the photooxidation of unidirectional (UD) composites based on recycled matrix, which is the aim of this work. For this purpose, UD flax fiber composites based on recycled polypropylene were prepared by thermocompression. An accelerated aging test was carried out using a xenon arc WeatherOmeter. The consequences of UV exposure on the chemical composition and morphology of the surface of composites as well as on their tensile mechanical properties have been reported. The results showed that accelerated aging had a significant effect on the surface of these composites while it had little impact on their mechanical properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flax%20fiber" title="flax fiber">flax fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=photooxidation" title=" photooxidation"> photooxidation</a>, <a href="https://publications.waset.org/abstracts/search?q=physico-chemical%20properties" title=" physico-chemical properties"> physico-chemical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20polypropylene" title=" recycled polypropylene"> recycled polypropylene</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20properties" title=" tensile properties"> tensile properties</a> </p> <a href="https://publications.waset.org/abstracts/141984/accelerated-ageing-of-unidirectional-flax-fibers-reinforced-recycled-polypropylene-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141984.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">199</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">63</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">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">62</span> A Constructivist Approach and Tool for Autonomous Agent Bottom-up Sequential Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jianyong%20Xue">Jianyong Xue</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20L.%20Georgeon"> Olivier L.

These abilities set them apart from even the most advanced autonomous robots. This work seeks to contribute to understand and replicate some of these abilities. We propose the Bottom-up hiErarchical sequential Learning algorithm with Constructivist pAradigm (BEL-CA) to design agents capable of learning autonomously and continuously through interactions. The algorithm implements no assumption about the semantics of input and output data. It does not rely upon a model of the world given a priori in the form of a set of states and transitions as well. Besides, we propose a toolkit to analyze the learning process at run time called GAIT (Generating and Analyzing Interaction Traces). We use GAIT to report and explain the detailed learning process and the structured behaviors that the agent has learned on each decision making. We report an experiment in which the agent learned to successfully interact with its environment and to avoid unfavorable interactions using regularities discovered through interaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cognitive%20development" title="cognitive development">cognitive development</a>, <a href="https://publications.waset.org/abstracts/search?q=constructivist%20learning" title=" constructivist learning"> constructivist learning</a>, <a href="https://publications.waset.org/abstracts/search?q=hierarchical%20sequential%20learning" title=" hierarchical sequential learning"> hierarchical sequential learning</a>, <a href="https://publications.waset.org/abstracts/search?q=self-adaptation" title=" self-adaptation"> self-adaptation</a> </p> <a href="https://publications.waset.org/abstracts/129145/a-constructivist-approach-and-tool-for-autonomous-agent-bottom-up-sequential-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129145.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">181</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">61</span> New Approach for Minimizing Wavelength Fragmentation in Wavelength-Routed WDM Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sami%20Baraketi">Sami Baraketi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean%20Marie%20Garcia"> Jean Marie Garcia</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Brun"> Olivier Brun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wavelength Division Multiplexing (WDM) is the dominant transport technology used in numerous high capacity backbone networks, based on optical infrastructures. Given the importance of costs (CapEx and OpEx) associated to these networks, resource management is becoming increasingly important, especially how the optical circuits, called “lightpaths”, are routed throughout the network. This requires the use of efficient algorithms which provide routing strategies with the lowest cost. We focus on the lightpath routing and wavelength assignment problem, known as the RWA problem, while optimizing wavelength fragmentation over the network. Wavelength fragmentation poses a serious challenge for network operators since it leads to the misuse of the wavelength spectrum, and then to the refusal of new lightpath requests. In this paper, we first establish a new Integer Linear Program (ILP) for the problem based on a node-link formulation. This formulation is based on a multilayer approach where the original network is decomposed into several network layers, each corresponding to a wavelength. Furthermore, we propose an efficient heuristic for the problem based on a greedy algorithm followed by a post-treatment procedure. The obtained results show that the optimal solution is often reached. We also compare our results with those of other RWA heuristic methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=WDM" title="WDM">WDM</a>, <a href="https://publications.waset.org/abstracts/search?q=lightpath" title=" lightpath"> lightpath</a>, <a href="https://publications.waset.org/abstracts/search?q=RWA" title=" RWA"> RWA</a>, <a href="https://publications.waset.org/abstracts/search?q=wavelength%20fragmentation" title=" wavelength fragmentation"> wavelength fragmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20programming" title=" linear programming"> linear programming</a>, <a href="https://publications.waset.org/abstracts/search?q=heuristic" title=" heuristic"> heuristic</a> </p> <a href="https://publications.waset.org/abstracts/25101/new-approach-for-minimizing-wavelength-fragmentation-in-wavelength-routed-wdm-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25101.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">527</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">60</span> Abdominal Pregnancy with a Live Newborn in a Low Resource Setting: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Mulisya">Olivier Mulisya</a>, <a href="https://publications.waset.org/abstracts/search?q=Guelord%20Barasima"> Guelord Barasima</a>, <a href="https://publications.waset.org/abstracts/search?q=Henry%20Mark%20Lugobe"> Henry Mark Lugobe</a>, <a href="https://publications.waset.org/abstracts/search?q=Phil%C3%A9mon%20Matumo"> Philémon Matumo</a>, <a href="https://publications.waset.org/abstracts/search?q=Bienfait%20Mumbere%20Vahwere"> Bienfait Mumbere Vahwere</a>, <a href="https://publications.waset.org/abstracts/search?q=Hilaire%20Mutuka"> Hilaire Mutuka</a>, <a href="https://publications.waset.org/abstracts/search?q=Zawadi%20L%C3%A9ocadie"> Zawadi Léocadie</a>, <a href="https://publications.waset.org/abstracts/search?q=Wesley%20Lumika"> Wesley Lumika</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Abdominal pregnancy is defined as pregnancy anywhere within the peritoneal cavity, exclusive of tubal, ovarian, or broad ligament locations. It is a rare form of ectopic pregnancy with high morbidity and mortality for both the mother and the fetus. Diagnosis can be frequently missed in most poor-resource settings because of poor antenatal coverage, low socioeconomic status in most of the patients as well as lack of adequate medical resources. Clinical diagnosis can be very difficult and an ultrasound scan is very helpful during the early stages of gestation but can also be disappointing in the later stages. We report a case of a 25-year-old woman with severe abdominal pain not amended with any medication. A clinical picture of shock lead to an emergency laparotomy which confirmed the diagnosis of abdominal pregnancy. The ministry of health in developing countries should make an effort to make routine early ultrasounds accessible to pregnant women, and obstetricians should keep in mind the possibility of ectopic pregnancy, irrespective of the gestational age. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abdominal%20pregnancy" title="abdominal pregnancy">abdominal pregnancy</a>, <a href="https://publications.waset.org/abstracts/search?q=live%20new%20bron" title=" live new bron"> live new bron</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound%20imaging" title=" ultrasound imaging"> ultrasound imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=abdominal%20pain" title=" abdominal pain"> abdominal pain</a> </p> <a href="https://publications.waset.org/abstracts/163482/abdominal-pregnancy-with-a-live-newborn-in-a-low-resource-setting-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163482.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">99</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">59</span> Fund Seekers’ Deception in Peer-to-Peer Lending in Times of COVID</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Mesly">Olivier Mesly</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article examines the likelihood of deception on the part of borrowers wishing to obtain credit from institutional or private lenders. In our first study, we identify five explanatory variables that account for nearly forty percent of the propensity to act deceitfully: a poor credit history, debt, risky behavior, and to a much lesser degree, irrational behavior and disconnection from the bundle of needs, goals, and preferences. For the second study, we remodeled the initial questionnaire to adapt it to the needs of institutional bankers and borrowers, especially those that engage in money on-line peer-to-peer lending, a growing business fueled by the COVID pandemic. We find that the three key psychological variables that help to indirectly predict the likelihood of deceitful behaviors and possible default on loan reimbursement, i.e., risky behaviors, ir-rationality, and dis-connection, interact with each other to form a loop. This study presents two benefits: first, we provide evidence that it is to some degree possible to tighten control over lending practices. Second, we offer a pragmatic tool: a questionnaire, that lenders can use or adapt to gauge potential borrowers’ deceit, notably by combining their results with standard hard-data measures of risk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bundle%20of%20needs" title="bundle of needs">bundle of needs</a>, <a href="https://publications.waset.org/abstracts/search?q=default" title=" default"> default</a>, <a href="https://publications.waset.org/abstracts/search?q=debt" title=" debt"> debt</a>, <a href="https://publications.waset.org/abstracts/search?q=deception" title=" deception"> deception</a>, <a href="https://publications.waset.org/abstracts/search?q=risk" title=" risk"> risk</a>, <a href="https://publications.waset.org/abstracts/search?q=peer-to-peer%20lending" title=" peer-to-peer lending"> peer-to-peer lending</a> </p> <a href="https://publications.waset.org/abstracts/146408/fund-seekers-deception-in-peer-to-peer-lending-in-times-of-covid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146408.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">132</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">58</span> Nonlinear Analysis of Postural Sway in Multiple Sclerosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hua%20Cao">Hua Cao</a>, <a href="https://publications.waset.org/abstracts/search?q=Laurent%20Peyrodie"> Laurent Peyrodie</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Agnani"> Olivier Agnani</a>, <a href="https://publications.waset.org/abstracts/search?q=Cecile%20Donze"> Cecile Donze</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Multiple sclerosis (MS) is a disease, which affects the central nervous system, and causes balance problem. In clinical, this disorder is usually evaluated using static posturography. Some linear or nonlinear measures, extracted from the posturographic data (i.e. center of pressure, COP) recorded during a balance test, has been used to analyze postural control of MS patients. In this study, the trend (TREND) and the sample entropy (SampEn), two nonlinear parameters were chosen to investigate their relationships with the expanded disability status scale (EDSS) score. Forty volunteers with different EDSS scores participated in our experiments with eyes open (EO) and closed (EC). TREND and two types of SampEn (SampEn1 and SampEn2) were calculated for each combined COP’s position signal. The results have shown that TREND had a weak negative correlation to EDSS while SampEn2 had a strong positive correlation to EDSS. Compared to TREND and SampEn1, SampEn2 showed a better significant correlation to EDSS and an ability to discriminate the MS patients in the EC case. In addition, the outcome of the study suggests that the multi-dimensional nonlinear analysis could provide some information about the impact of disability progression in MS on dynamics of the COP data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=balance" title="balance">balance</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20sclerosis" title=" multiple sclerosis"> multiple sclerosis</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20analysis" title=" nonlinear analysis"> nonlinear analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=postural%20sway" title=" postural sway"> postural sway</a> </p> <a href="https://publications.waset.org/abstracts/40541/nonlinear-analysis-of-postural-sway-in-multiple-sclerosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40541.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">338</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">57</span> An Attenuated Quadruple Gene Mutant of Mycobacterium tuberculosis Imparts Protection against Tuberculosis in Guinea Pigs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shubhita%20Mathur">Shubhita Mathur</a>, <a href="https://publications.waset.org/abstracts/search?q=Ritika%20Kar%20Bahal"> Ritika Kar Bahal</a>, <a href="https://publications.waset.org/abstracts/search?q=Priyanka%20Chauhan"> Priyanka Chauhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Anil%20K.%20Tyagi"> Anil K. Tyagi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mycobacterium tuberculosis, the causative agent of human tuberculosis, is a major cause of mortality. Bacillus Calmette-Guérin (BCG), the only licensed vaccine available for protection against tuberculosis confers highly variable protection ranging from 0%-80%. Thus, novel vaccine strains need to be evaluated for their potential as a vaccine against tuberculosis. We had previously constructed a triple gene mutant of M. tuberculosis (MtbΔmms), having deletions in genes encoding for phosphatases mptpA, mptpB, and sapM that are involved in host-pathogen interaction. Though vaccination with Mtb∆mms strain induced protection in the lungs of guinea pigs, the mutant strain was not able to control the hematogenous spread of the challenge strain to the spleens. Additionally, inoculation with Mtb∆mms resulted in some pathological damage to the spleens in the early phase of infection. In order to overcome the pathology caused by MtbΔmms in the spleens of guinea pigs and also to control the dissemination of the challenge strain, MtbΔmms was genetically modified by disrupting bioA gene to generate MtbΔmmsb strain. Further, in vivo attenuation of MtbΔmmsb was evaluated, and its protective efficacy was assessed against virulent M. tuberculosis challenge in guinea pigs. Our study demonstrates that Mtb∆mmsb mutant was highly attenuated for growth and virulence in guinea pigs. Vaccination with Mtb∆mmsb mutant generated significant protection in comparison to sham-immunized animals at 4 and 12 weeks post-infection in lungs and spleens of the infected animals. Our findings provide evidence that deletion of genes involved in signal transduction and biotin biosynthesis severely attenuates the pathogen and the single immunization with the auxotroph was able to provide significant protection as compared to sham-immunized animals. The protection imparted by Mtb∆mmsb fell short in comparison to the protection observed in BCG-immunized animals. This study nevertheless indicates the importance of attenuated multiple gene deletion mutants of M. tuberculosis in generating protection against tuberculosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mycobacterium%20tuberculosis" title="Mycobacterium tuberculosis">Mycobacterium tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=BCG" title=" BCG"> BCG</a>, <a href="https://publications.waset.org/abstracts/search?q=Mtb%CE%94mmsb" title=" MtbΔmmsb"> MtbΔmmsb</a>, <a href="https://publications.waset.org/abstracts/search?q=bioA" title=" bioA"> bioA</a>, <a href="https://publications.waset.org/abstracts/search?q=guinea%20pigs" title=" guinea pigs"> guinea pigs</a> </p> <a href="https://publications.waset.org/abstracts/109444/an-attenuated-quadruple-gene-mutant-of-mycobacterium-tuberculosis-imparts-protection-against-tuberculosis-in-guinea-pigs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109444.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">140</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">56</span> Determining a Bilingualism Index: Evidence From Lebanese Control Bilinguals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rania%20Kassir">Rania Kassir</a>, <a href="https://publications.waset.org/abstracts/search?q=Christophe%20Dos%20Santos"> Christophe Dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Halim%20Abboud"> Halim Abboud</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Godefroy"> Olivier Godefroy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ability to communicate in at least two different languages is shared by a growing number of humans. Recently, many researchers have been studying the elderly bilingual population around the world in neuroscience, and yet, until today there’s no accurate nor universal measure or methodology used to examine bilingualism across these studies which constitute a real challenge for results generalization. This study contributes to the quest of a multidimensional bilingualism index and language proficiency literature by investigating a new bilingualism index from a reliable subjective questionnaire the Language Experience and Proficiency Questionnaire (LEAP-Q), multi-linguistic tests, and a diverse bilingual population all featured in one analysis and one index. One hundred Lebanese subjects aged between 55 and 92 years old divided into three different bilingualism subgroups (Arabic prominent, balanced, and French prominent) were recruited and underwent the LEAP-Q with a set of linguistic and cognitive tests. The analysis of the collected data led to the creation of a robust bilingualism index from speaking and oral understanding scores that underline specifically bilingualism subtype according to cutoffs scored. The practice implications of this index, particularly its use within bilingual populations, are addressed in the conclusion of this work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bilingualism" title="bilingualism">bilingualism</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20dominance" title=" language dominance"> language dominance</a>, <a href="https://publications.waset.org/abstracts/search?q=bilingualism%20index" title=" bilingualism index"> bilingualism index</a>, <a href="https://publications.waset.org/abstracts/search?q=balanced%20bilingualism" title=" balanced bilingualism"> balanced bilingualism</a>, <a href="https://publications.waset.org/abstracts/search?q=Arabic%20first%20language" title=" Arabic first language"> Arabic first language</a>, <a href="https://publications.waset.org/abstracts/search?q=Lebanese" title=" Lebanese"> Lebanese</a>, <a href="https://publications.waset.org/abstracts/search?q=Arabic-French%20bilingualism" title=" Arabic-French bilingualism"> Arabic-French bilingualism</a> </p> <a href="https://publications.waset.org/abstracts/147829/determining-a-bilingualism-index-evidence-from-lebanese-control-bilinguals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147829.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">129</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">55</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.

To face the limitations of existing Flash memory cells (endurance, downscaling, rapidity…), new approaches are emerging, among them resistive switching memories (Re-RAM). In this work, we analysed the behaviour of LixCoO2 oxide thin films in electrode/film/electrode devices. Preliminary results have been obtained concerning the influence of bias pulses characteristics (duration, value) on some performance parameters, such as endurance and resistance ratio (ROFF/RON). Besides, Conducting Probe Atomic Force Microscopy (CP-AFM) characterizations of the devices have been carried out to better understand some causes of performance failure, and thus help optimizing the switching performance of such devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=non%20volatile%20resistive%20memories" title="non
