Two structural units are distinguished: a Palaeozoic basement and a Mesozoic cover. The study area is densely faulted and major faults strike N110° to N140° and dip vertically The mineralized fault zones are readily distinguishable by their argillic wall rock alteration. The fault zones that are filled with mineralizations, aplites, microgranites and quartz run roughly parallel to each other and are apparently in the same fault system. The Palaeozoic basement rocks contain mineralization occurring as veins, veinlets and disseminations. The Liassic carbonate platform sequence contains Ba (Pb-Zn) sulphide deposits occurring mainly as strata bound, and open space filling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Algeria" title="Algeria">Algeria</a>, <a href="https://publications.waset.org/abstracts/search?q=basement" title=" basement"> basement</a>, <a href="https://publications.waset.org/abstracts/search?q=Beni%20Snouss" title=" Beni Snouss"> Beni Snouss</a>, <a href="https://publications.waset.org/abstracts/search?q=cover" title=" cover"> cover</a> </p> <a href="https://publications.waset.org/abstracts/41823/geological-characteristics-of-the-beni-snouss-district" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41823.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">386</span> First-Principles Density Functional Study of Nitrogen-Doped P-Type ZnO</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdusalam%20Gsiea">Abdusalam Gsiea</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramadan%20Al-habashi"> Ramadan Al-habashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Atumi"> Mohamed Atumi</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Atmimi"> Khaled Atmimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present a theoretical investigation on the structural, electronic properties and vibrational mode of nitrogen impurities in ZnO.

Based on Local density functional theory, our calculations are in agreement with one interpretation of bound-excition photoluminescence for N-doped ZnO. First-principles calculations show that (NO3)i defects interstitial or NO4 substituting on an Oxygen site in ZnO are important suitable impurity for p-type doping in ZnO. However, many experimental efforts have not resulted in reproducible p-type material with N2 and N2O doping. by means of first-principle pseudo-potential calculation we find that the use of NO or NO2 with O gas might help the experimental research to resolve the challenge of achieving p-type ZnO. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DFF" title="DFF">DFF</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrogen" title=" nitrogen"> nitrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=p-type" title=" p-type"> p-type</a>, <a href="https://publications.waset.org/abstracts/search?q=ZnO" title=" ZnO"> ZnO</a> </p> <a href="https://publications.waset.org/abstracts/46018/first-principles-density-functional-study-of-nitrogen-doped-p-type-zno" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46018.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">463</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">385</span> Dynamics of Plant Communities with Chamaerops humilis in the Region of Tlemcen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20Hasnaoui">O.

Chamaerops humilis covers a big surface in this region, which appears in the majority of the cases in the form of more or less degraded matorral. Our work is dedicated to the comparative analysis of the groupings in chamaeropaie of the mounts of Tlemcen and mounts of traras, based on a phytoécologique approach. Four representative stations of chamaeropaies were retained to make this work. 120 floristic surveys were realized by using a minimal area of 100 m2. The obtained results show that the Mounts of Tlemcen present a wealth more important than those met at the level of the Mounts of Traras. More we go away from the coast towards the Mounts of Tlemcen, we notice a regressive evolution and a transformation of the plant carpet towards a thérophytisation, as well as an accentuation of the aridity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tlemcen" title="Tlemcen">Tlemcen</a>, <a href="https://publications.waset.org/abstracts/search?q=west%20Algeria" title=" west Algeria"> west Algeria</a>, <a href="https://publications.waset.org/abstracts/search?q=Chamaerops%20humilis%20L." title=" Chamaerops humilis L."> Chamaerops humilis L.</a>, <a href="https://publications.waset.org/abstracts/search?q=phyto%C3%A9cological" title=" phytoécological"> phytoécological</a>, <a href="https://publications.waset.org/abstracts/search?q=floristic%20survey" title=" floristic survey"> floristic survey</a>, <a href="https://publications.waset.org/abstracts/search?q=th%C3%A9rophytisation" title=" thérophytisation"> thérophytisation</a> </p> <a href="https://publications.waset.org/abstracts/34223/dynamics-of-plant-communities-with-chamaerops-humilis-in-the-region-of-tlemcen" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34223.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">384</span> The Effectiveness of Traditional Music as Therapy and Alternative to Traditional Forms of Therapy in Treatment of Anxiety and Depression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Helen%20Johnson-Egemba">Helen Johnson-Egemba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper will discuss the current effectiveness of music therapy for a range of conditions, such as depression and anxiety. Indeed, traditional forms of therapy have often been effective in treating various mental and physical health conditions. However, they are not with their limitations. Music therapy, on the other hand, is a non-invasive and cost-effective alternative that can produce similar or even better results. Music therapy can produce longer-lasting results. The research also highlights the underlying mechanisms of traditional music therapy, such as its complementary treatment. A systematic review of existing literature was conducted to gather relevant studies and establish a comprehensive understanding of the topic. Various research methods, including experimental studies, qualitative research, surveys, were utilized to explore the therapeutic potential of traditional music interventions. The findings reveal that traditional music therapy shows promise in managing anxiety and depression symptoms, with positive outcomes impacting brain activity, emotions, and stress regulation. The outcomes of this study contribute to evidence-based practice, providing insights for clinicians and therapists to incorporate traditional music therapy into their treatment approaches. Furthermore, the research promotes awareness and acceptance of traditional music as a legitimate and effective therapeutic intervention for anxiety and depression, potentially enhancing access to alternative and complementary treatment options. Overall, this study demonstrates the potential benefits of traditional music therapy in addressing anxiety and depression, offering valuable implications for mental health care and improving the well-being of individuals struggling with these conditions. <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=effectiveness" title=" effectiveness"> effectiveness</a>, <a href="https://publications.waset.org/abstracts/search?q=depression" title=" depression"> depression</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20music" title=" traditional music"> traditional music</a>, <a href="https://publications.waset.org/abstracts/search?q=therapy" title=" therapy"> therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment" title=" treatment"> treatment</a> </p> <a href="https://publications.waset.org/abstracts/186178/the-effectiveness-of-traditional-music-as-therapy-and-alternative-to-traditional-forms-of-therapy-in-treatment-of-anxiety-and-depression" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186178.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">45</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">383</span> 'Infection in the Sentence': The Castration of a Black Woman's Dream of Authorship as Manifested in Buchi Emecheta's Second Class Citizen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aseel%20Hatif%20Jassam">Aseel Hatif Jassam</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadeel%20Hatif%20Jassam"> Hadeel Hatif Jassam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper discusses the phallocentric discourse that is challenged by women in general and of women of color in particular in spite of the simultaneity of oppression due to race, class, and gender in the diaspora. Therefore, the paper gives a brief account of women's experience in the light of postcolonial feminist theory. The paper also cast light on the theories of Luce Irigaray and Helen Cixous, two Feminist theorists who support and advise women to have their own discourse to challenge the infectious patriarchal sentence advocated by Sigmund Freud and Harold Bloom's model of literary history. Black women authors like BuchiEmecheta as well as her alter ego Adah, a Nigerian-born girl and the protagonist of her semi-autobiographical novel, Second Class Citizen, suffer from this phallocentric and oppressive sentence and displacement as they migrate from Nigeria, a former British colony where they feel marginalized to North London with the hope of realizing their dreams. Yet, in the British diaspora, they get culturally shocked and continue to suffer from further marginalization due to class and race and are insulted and interiorized ironically by their patriarchal husbands who try to put an end to their dreams of authorship. With the phallocentric belief that women aren't capable of self-representation in the background of their mindsets, the violent Sylvester Onwordi and Francis Obi, the husbands of both Emecheta and Adah, respectively have practiced oppression on them by burning their own authoritative voice, represented by the novels they write while they are struggling with their economically atrocious living experience in the British diaspora. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=authorship" title="authorship">authorship</a>, <a href="https://publications.waset.org/abstracts/search?q=British%20diaspora" title=" British diaspora"> British diaspora</a>, <a href="https://publications.waset.org/abstracts/search?q=discourse" title=" discourse"> discourse</a>, <a href="https://publications.waset.org/abstracts/search?q=phallocentric" title=" phallocentric"> phallocentric</a>, <a href="https://publications.waset.org/abstracts/search?q=patriarchy" title=" patriarchy"> patriarchy</a> </p> <a href="https://publications.waset.org/abstracts/143968/infection-in-the-sentence-the-castration-of-a-black-womans-dream-of-authorship-as-manifested-in-buchi-emechetas-second-class-citizen" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143968.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">177</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">382</span> Bayesian Optimization for Reaction Parameter Tuning: An Exploratory Study of Parameter Optimization in Oxidative Desulfurization of Thiophene</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aman%20Sharma">Aman Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Sonali%20Sengupta"> Sonali Sengupta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study explores the utility of Bayesian optimization in tuning the physical and chemical parameters of reactions in an offline experimental setup.

Samples were selected horizontally and vertically from Esa-Odo Reservoir using improvised Meyer’s water sampler. Planktonic samples were collected at two months intervals for two years. Net and total plankton were sampled by filtration and sedimentation methods. Planktonic samples were preserved as 5% formalin and 1% Lugol’s solution. Measurement, enumeration, and scaled pictures of the recorded zooplankton were taken using a photomicrograph. The taxonomic composition of zooplankton biota was determined using identification keys. Eighty three (83) species of zooplankton recorded in this study belong to 4 groups: Rotifera, Cladocera, Copepoda, and Insecta. Rotifera was the most represented group (61.21%). Horizontally, 24 species with the highest mean abundance characterized the lacustrine; while 12 species and 10 species were unique to the transition and riverine zones, respectively. Vertically, most species had their mean abundance decreased from the surface to the bottom of the reservoir. A total of nine (9), two (2), and one (1) species were peculiar to the surface, bottom and mid-depth, respectively. Zooplankton was most abundant during the dry season. In conclusion, Esa-Odo Reservoir comprised highly diversified zooplankton fauna with great potential to support a rich aquatic community and fishery production. The reservoir can be classified as fairly clean based on the abundance of the rotifer group. However, the lake should be subjected to regular proper monitoring because of the presence of some pollution tolerant copepod species identified among the zooplankton fauna. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=zooplankton" title="zooplankton">zooplankton</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial" title=" spatial"> spatial</a>, <a href="https://publications.waset.org/abstracts/search?q=temporal" title=" temporal"> temporal</a>, <a href="https://publications.waset.org/abstracts/search?q=abundance" title=" abundance"> abundance</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title=" biodiversity"> biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=reservoir" title=" reservoir"> reservoir</a> </p> <a href="https://publications.waset.org/abstracts/145056/spacio-temporal-variation-of-the-zooplanktonic-community-of-esa-odo-reservoir-esa-odo-osun-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145056.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">97</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">380</span> New Results on Exponential Stability of Hybrid Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Grienggrai%20Rajchakit">Grienggrai Rajchakit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is concerned with the exponential stability of switched linear systems with interval time-varying delays.

The development of the transport is in the center of the big challenges of development of countries, but it is also at the heart of big contradictions, since we integrate the environmental issues which are bound to him, in particular through the questions of energy. Indeed, the energy consumption by the sector of transport is one of bigger concerns, because it is increasing and it has a big impact on our environment. The main consequences are, the atmospheric pollution causing an increase of the greenhouse effect which causes a global warming. These global warming risks to engender a partial cast iron of polar caps so raising the level of seas, flooding the low coastal zones, certain islands and the deltas. Thus, the purpose of this communication is to present the impact of the energy consumption by the sector of transport on the air quality, showing its effect on the health and on the global warming. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20consumption" title="energy consumption">energy consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=sector%20of%20transport" title=" sector of transport"> sector of transport</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20quality" title=" air quality"> air quality</a>, <a href="https://publications.waset.org/abstracts/search?q=atmospheric%20pollution" title=" atmospheric pollution"> atmospheric pollution</a> </p> <a href="https://publications.waset.org/abstracts/11918/the-energy-consumption-by-the-sector-of-transport-and-his-impact-on-the-atmospheric-pollution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11918.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">331</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">377</span> Hygro-Thermal Modelling of Timber Decks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stefania%20Fortino">Stefania Fortino</a>, <a href="https://publications.waset.org/abstracts/search?q=Petr%20Hradil"> Petr Hradil</a>, <a href="https://publications.waset.org/abstracts/search?q=Timo%20Avikainen"> Timo Avikainen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Timber bridges have an excellent environmental performance, are economical, relatively easy to build and can have a long service life. However, the durability of these bridges is the main problem because of their exposure to outdoor climate conditions. The moisture content accumulated in wood for long periods, in combination with certain temperatures, may cause conditions suitable for timber decay. In addition, moisture content variations affect the structural integrity, serviceability and loading capacity of timber bridges. Therefore, the monitoring of the moisture content in wood is important for the durability of the material but also for the whole superstructure. The measurements obtained by the usual sensor-based techniques provide hygro-thermal data only in specific locations of the wood components. In this context, the monitoring can be assisted by numerical modelling to get more information on the hygro-thermal response of the bridges. This work presents a hygro-thermal model based on a multi-phase moisture transport theory to predict the distribution of moisture content, relative humidity and temperature in wood. Below the fibre saturation point, the multi-phase theory simulates three phenomena in cellular wood during moisture transfer, i.e., the diffusion of water vapour in the pores, the sorption of bound water and the diffusion of bound water in the cell walls. In the multi-phase model, the two water phases are separated, and the coupling between them is defined through a sorption rate. Furthermore, an average between the temperature-dependent adsorption and desorption isotherms is used. In previous works by some of the authors, this approach was found very suitable to study the moisture transport in uncoated and coated stress-laminated timber decks. Compared to previous works, the hygro-thermal fluxes on the external surfaces include the influence of the absorbed solar radiation during the time and consequently, the temperatures on the surfaces exposed to the sun are higher. This affects the whole hygro-thermal response of the timber component. The multi-phase model, implemented in a user subroutine of Abaqus FEM code, provides the distribution of the moisture content, the temperature and the relative humidity in a volume of the timber deck. As a case study, the hygro-thermal data in wood are collected from the ongoing monitoring of the stress-laminated timber deck of Tapiola Bridge in Finland, based on integrated humidity-temperature sensors and the numerical results are found in good agreement with the measurements. The proposed model, used to assist the monitoring, can contribute to reducing the maintenance costs of bridges, as well as the cost of instrumentation, and increase safety. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=moisture%20content" title="moisture content">moisture content</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-phase%20models" title=" multi-phase models"> multi-phase models</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20radiation" title=" solar radiation"> solar radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=timber%20decks" title=" timber decks"> timber decks</a>, <a href="https://publications.waset.org/abstracts/search?q=FEM" title=" FEM"> FEM</a> </p> <a href="https://publications.waset.org/abstracts/141108/hygro-thermal-modelling-of-timber-decks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141108.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">175</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">376</span> Numerical Simulation and Experimental Validation of the Tire-Road Separation in Quarter-car Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Quy%20Dang%20Nguyen">Quy Dang Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Nakhaie%20Jazar"> Reza Nakhaie Jazar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper investigates vibration dynamics of tire-road separation for a quarter-car model; this separation model is developed to be close to the real situation considering the tire is able to separate from the ground plane.

With the elevation of temperature, there can be a notable increase in intrinsic permeability due to the degeneration of bound water molecules into a free state facilitated by thermal energy input. Conversely, thermal consolidation may cause a reduction in intrinsic permeability as soil particles undergo densification. This thermal response of soil permeability exhibits pronounced heterogeneity across different soil types. Furthermore, this temperature-induced disruption of the bound water within clay matrices can enhance the mineral-to-mineral contact, initiating irreversible deformation within the clay structure. This indicates that when soil undergoes heating-cooling cycles, plastic strain can develop, which needs to be investigated for every soil type to understand the thermo-hydro mechanical behavior of clay properly. This research aims to study the effect of the heating-cooling cycle on the intrinsic permeability and time-dependent evaluation of thermal volume change of sodium Bentonite clay. A temperature-controlled triaxial permeameter cell is used in this study. The selected temperature is 20° C, 40° C, 40° C and 80° C. The hydraulic conductivity of Bentonite clay under 100 kPa confining stresses was measured. Hydraulic conductivity analysis was performed on a saturated sample for a void ratio e = 0.9, corresponding to a dry density of 1.2 Mg/m3. Different hydraulic gradients were applied between the top and bottom of the sample to obtain a measurable flow through the sample. The hydraulic gradient used for the experiment was 4000. The diameter and thickness of the sample are 101. 6 mm, and 25.4 mm, respectively. Both for heating and cooling, the hydraulic conductivity at each temperature is measured after the flow reaches the steady state condition to make sure the volume change due to thermal loading is stabilized. Thus, soil specimens were kept at a constant temperature during both the heating and cooling phases for at least 10-18 days to facilitate the equilibration of hydraulic transients. To assess the influence of temperature-induced volume changes of Bentonite clay, the evaluation of void ratio change during this time period has been monitored. It is observed that the intrinsic permeability increases by 30-40% during the heating cycle. The permeability during the cooling cycle is 10-12% lower compared to the permeability observed during the heating cycle at a particular temperature. This reduction in permeability implies a change in soil fabric due to the thermal effect. An initial increase followed by a rapid decrease in void ratio was observed, representing the occurrence of possible osmotic swelling phenomena followed by thermal consolidation. It has been observed that after a complete heating-cooling cycle, there is a significant change in the void ratio compared to the initial void ratio of the sample. The results obtained suggest that Bentonite clay’s microstructure can change subject to a complete heating-cooling process, which regulates macro behavior such as the permeability of Bentonite clay. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bentonite" title="bentonite">bentonite</a>, <a href="https://publications.waset.org/abstracts/search?q=permeability" title=" permeability"> permeability</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20volume%20change" title=" thermal volume change"> thermal volume change</a> </p> <a href="https://publications.waset.org/abstracts/186783/effect-of-temperature-on-the-permeability-and-time-dependent-change-in-thermal-volume-of-bentonite-clay-during-the-heating-cooling-cycle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186783.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">49</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">369</span> A Finite Element Study of Laminitis in Horses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naeim%20Akbari%20Shahkhosravi">Naeim Akbari Shahkhosravi</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Kakavand"> Reza Kakavand</a>, <a href="https://publications.waset.org/abstracts/search?q=Helen%20M.%20S.%20Davies"> Helen M.

This disease exhibits the mechanical properties degradation of the laminar junction tissue within the hoof. Therefore, it is essential to investigate the biomechanics of the hoof, focusing specifically on excessive and cumulatively accumulated stresses within the laminar junction tissue. For this aim, the current study generated a novel equine hoof Finite Element (FE) model under dynamic physiological loading conditions and employing a hyperelastic material model. Associated tissues of the equine hoof were segmented from computed tomography scans of an equine forelimb, including the navicular bone, third phalanx, sole, frog, laminar junction, digital cushion, and medial- dorsal- lateral wall areas. The inner tissues were connected based on the hoof anatomy, and the hoof was under a dynamic loading over cyclic strides at the trot. The strain distribution on the hoof wall of the model was compared with the published in vivo strain measurements to validate the model. Then the validated model was used to study the development of laminitis. The ultimate stress tolerated by the laminar junction before rupture was considered as a stress threshold. The tissue damage was simulated through iterative reduction of the tissue’s mechanical properties in the presence of excessive maximum principal stresses. The findings of this investigation revealed how damage initiates from the medial and lateral sides of the tissue and propagates through the hoof dorsal area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=horse%20hoof" title="horse hoof">horse hoof</a>, <a href="https://publications.waset.org/abstracts/search?q=laminitis" title=" laminitis"> laminitis</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20model" title=" finite element model"> finite element model</a>, <a href="https://publications.waset.org/abstracts/search?q=continuous%20damage" title=" continuous damage"> continuous damage</a> </p> <a href="https://publications.waset.org/abstracts/141669/a-finite-element-study-of-laminitis-in-horses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141669.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">182</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">368</span> Stability of Hybrid Stochastic Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manlika%20Ratchagit">Manlika Ratchagit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is concerned with robust mean square stability of uncertain stochastic switched discrete time-delay systems.

The optimization problem aims to obtain the composition of the best product mix in a non-homogeneous industrial plant, with the lowest cost until the breakeven point is reached. The problem constraints represent real limitations of a generic non-homogeneous industrial plant for n different products. The proposed model is able to solve the equilibrium point problem simultaneously for all products, unlike the existing approaches that propose a resolution in a sequential way, considering each product in isolation and providing a sub-optimal solution to the problem. The results indicate that the product mix found through the proposed model has economical advantages over the traditional approach used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=branch%20and%20bound" title="branch and bound">branch and bound</a>, <a href="https://publications.waset.org/abstracts/search?q=break-even%20point" title=" break-even point"> break-even point</a>, <a href="https://publications.waset.org/abstracts/search?q=non-homogeneous%20production%20system" title=" non-homogeneous production system"> non-homogeneous production system</a>, <a href="https://publications.waset.org/abstracts/search?q=integer%20linear%20programming" title=" integer linear programming"> integer linear programming</a>, <a href="https://publications.waset.org/abstracts/search?q=management%20accounting" title=" management accounting"> management accounting</a> </p> <a href="https://publications.waset.org/abstracts/143328/mathematical-modeling-for-the-break-even-point-problem-in-a-non-homogeneous-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143328.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">211</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">365</span> Carcinogenic Polycyclic Aromatic Hydrocarbons in Urban Air Particulate Matter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Szab%C3%B3%20Nagy">A.

A high volume sampler was used for the collection of ambient aerosol particles, and the associated cPAH compounds (benzo[a]pyrene (BaP), benzo[a]anthracene, benzofluoranthene isomers, indeno[123-cd]pyrene and dibenzo[ah]anthracene) were analyzed by a gas chromatographic method. Higher mean concentrations of total cPAHs were detected in samples collected in winter (9.62 ng/m<sup>3</sup>) and autumn (2.69 ng/m<sup>3</sup>) compared to spring (1.05 ng/m<sup>3</sup>) and summer (0.21 ng/m<sup>3</sup>). The calculated <em>BaP</em> <em>toxic equivalent concentrations</em> have also reflected that the local population appears to be exposed to significantly higher cancer risk in the heating seasons. Moreover, the concentration levels of cPAHs determined in this study were compared to other Hungarian urban sites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air" title="air">air</a>, <a href="https://publications.waset.org/abstracts/search?q=carcinogenic" title=" carcinogenic"> carcinogenic</a>, <a href="https://publications.waset.org/abstracts/search?q=polycyclic%20aromatic%20hydrocarbons%20%28PAH%29" title=" polycyclic aromatic hydrocarbons (PAH)"> polycyclic aromatic hydrocarbons (PAH)</a>, <a href="https://publications.waset.org/abstracts/search?q=PM10" title=" PM10"> PM10</a> </p> <a href="https://publications.waset.org/abstracts/67011/carcinogenic-polycyclic-aromatic-hydrocarbons-in-urban-air-particulate-matter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67011.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">272</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">364</span> The Interface of Tradition and Modernity in Black South African Women's Experiences of Menstruation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anita%20Padmanabhanunni">Anita Padmanabhanunni</a>, <a href="https://publications.waset.org/abstracts/search?q=Labeeqah%20Jaffer"> Labeeqah Jaffer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Menstruation signifies the transition to biological sexual maturity and culture-bound values influence its meaning and experience for women. In South Africa there is a paucity of research specific to the topic of menstruation. This study addresses this gap in the literature by exploring the experiences of menstruation among a group of women from the ama-Xhosa ethnic group, one of the largest ethnic groups in the country. Focus group and individual interviews were conducted with ama-Xhosa woman (n= 15). Data was analyzed using thematic analysis. The study found that traditional knowledge systems and cultural practices associated with menstruation including virginity testing and intonjane (female right of passage) still exist and impact on women’s subjective experiences.

When organisations, particularly Small, Medium and Micro Enterprises (SMMEs), do not use budgets, they are bound to fail in their infancy stage. The aim of this study was to assess whether or not SMMEs in South Africa used budgets as an effective management tool during the COVID-19 pandemic. For the purposes of this study, data was collected using an online questionnaire (survey). This study used the quantitative research approach. The study used descriptive statistics to analyse the research question. The study found that most SMMEs did not use budgets during the COVID-19 pandemic; one of the reasons, amongst others, was that most of them had to close down during the lockdown, and some of them did not even qualify for government bailout or government grants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=budget%20management" title="budget management">budget management</a>, <a href="https://publications.waset.org/abstracts/search?q=SMMEs" title=" SMMEs"> SMMEs</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title=" COVID-19"> COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Africa" title=" South Africa"> South Africa</a> </p> <a href="https://publications.waset.org/abstracts/142064/the-use-of-budgeting-as-an-effective-management-tool-for-small-medium-and-micro-enterprises-during-covid-19-pandemic-a-perspective-from-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142064.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">192</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">361</span> An Evaluation of Air Pollutant Concentrations in Gyor, Hungary</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Szabo%20Nagy">Andrea Szabo Nagy</a>, <a href="https://publications.waset.org/abstracts/search?q=Zsofia%20Csanadi"> Zsofia Csanadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study was to evaluate the concentration levels of common inorganic gases, benzene and particulate matter (PM₁₀ and PM₂.₅) in ambient air of Győr (Hungary) based on the latest published monitoring data.

The absorbance data matrices were analyzed with a versatile chemometric procedure that provides the melting profile (distribution of species) and the pure spectrum for each chemical species present along the heating experiment. As revealed by the increase of Tm, the duplex structure was stabilized by these porphyrins. The values of stabilization temperature ΔTm in the presence of these porphyrins are relatively large, 1.2-8.4 °C, indicating that the porphyrins contribute differently in stabilizing the duplex Poly(A)-Poly(U) structure. Remarkable is the fact that the porphyrin TMPyP4 was less effective in the stabilization of the duplex structure than the metalloporphyrin Zn(X)TMPyP4 which suggests that metallization play an important role in porphyrin-RNA binding. Molecular Dynamics Simulations has been used to illustrate melting of the duplex dsRNA bound with a porphyrin molecule. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=melting" title="melting">melting</a>, <a href="https://publications.waset.org/abstracts/search?q=Poly%28A%29-Poly%28U%29" title=" Poly(A)-Poly(U)"> Poly(A)-Poly(U)</a>, <a href="https://publications.waset.org/abstracts/search?q=TMPyP4" title=" TMPyP4"> TMPyP4</a>, <a href="https://publications.waset.org/abstracts/search?q=Zn%28X%29TMPyP4" title=" Zn(X)TMPyP4"> Zn(X)TMPyP4</a> </p> <a href="https://publications.waset.org/abstracts/75747/thermal-stabilisation-of-polyapolyu-by-tmpyp4-and-znxtmpyp4-derivatives-in-aqueous-solutions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75747.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">359</span> Development of Gold Nanoparticles-Antibody System for the Selective Photothermal Destruction of Multidrug Resistant Bacteria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Teodora%20Mocan">Teodora Mocan</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucian%20Mocan"> Lucian Mocan</a>, <a href="https://publications.waset.org/abstracts/search?q=Cornel%20Iancu"> Cornel Iancu</a>, <a href="https://publications.waset.org/abstracts/search?q=Flaviu%20A.%20Tabaran"> Flaviu A.

At the current time, vancomycin is the only responsive treatment although has significant cytotoxicity, is partially effective and it is poorly retained by infected tissues. From a clinical point of view, attractive alternative approaches for treating such Meticillin-Resistant Staphylococcus Aureus (MRSA) strains would be using agents that cause physical damage to the bacteria. Modular nanopharmaceuticals systems are being designed to address all of these multifunctional capabilities for the ideal bacterial treatment, with the ability to mix and match appropriate functions. Here we present a novel method of selective laser photothermal ablation of MRSA bacteria mediated by gold nanoparticles bound to PBP antibody against PBP protein located on the MRSA surface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MRSA" title="MRSA">MRSA</a>, <a href="https://publications.waset.org/abstracts/search?q=laser" title=" laser"> laser</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticle" title=" nanoparticle"> nanoparticle</a>, <a href="https://publications.waset.org/abstracts/search?q=antibody" title=" antibody"> antibody</a> </p> <a href="https://publications.waset.org/abstracts/84089/development-of-gold-nanoparticles-antibody-system-for-the-selective-photothermal-destruction-of-multidrug-resistant-bacteria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84089.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">281</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">358</span> Retrospective Study on the Prognosis of Patients with New-Onset Atrial Fibrillation to Evaluate the Risk of Developing Occult Cancer in Absence of Concurrent Chronic Inflammatory Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Helen%20Huang">Helen Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Javier%20Quesada%20Ocet"> Francisco Javier Quesada Ocet</a>, <a href="https://publications.waset.org/abstracts/search?q=Blanca%20Quesada%20Oce"> Blanca Quesada Oce</a>, <a href="https://publications.waset.org/abstracts/search?q=Javier%20Jimenez%20Bello"> Javier Jimenez Bello</a>, <a href="https://publications.waset.org/abstracts/search?q=Victor%20Palanca%20Gil"> Victor Palanca Gil</a>, <a href="https://publications.waset.org/abstracts/search?q=Alba%20Cervero%20Rubio"> Alba Cervero Rubio</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Paya%20Chaume"> Ana Paya Chaume</a>, <a href="https://publications.waset.org/abstracts/search?q=Alejandro%20Herreros-Pomares"> Alejandro Herreros-Pomares</a>, <a href="https://publications.waset.org/abstracts/search?q=Fernando%20Vidal-Vanaclocha"> Fernando Vidal-Vanaclocha</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafael%20Paya%20Serrano"> Rafael Paya Serrano</a>, <a href="https://publications.waset.org/abstracts/search?q=Aurelio%20Quesada%20Dorador"> Aurelio Quesada Dorador</a>, <a href="https://publications.waset.org/abstracts/search?q=Monica%20Soliman"> Monica Soliman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Cancer favors both the pro-inflammatory state and autonomic dysfunction, two important mechanisms in the genesis of AF. Atrial remodeling might be caused as a result of paraneoplastic conditions or the result of direct expression of neoplasia. Here, we hypothesize that cancer, through inflammatory mediators, may favor the appearance of AF and patients with the first episode of AF could have a higher risk of developing cancer. Method: Data was collected from patients who attended the emergency department of our hospital for the first episode of AF, diagnosed electrocardiographically, between 2010-2015 (n = 712). The minimum follow-up was 2 years, recording the appearance of cancer, total mortality, recurrences of AF and other events. Patients who developed cancer and those who did not during the 2 years after the onset of AF were compared, as well as with the incidence of cancer in Spain in 2012. Results: After 2 years, 35 patients (4.91%) were diagnosed with cancer, with an annual incidence of 2.45%. Hematological neoplasms were the most frequent (34.28%). The cancer group was older (76.68 +/-12.75 years vs 74.16 +/-12.71; p <0.05) and had fewer typical symptoms (palpitations) (33.38% vs 14.28% , p <0.05). The incidence of cancer in Spain during 2012 was 0.46%, much lower than our sample. When comparing the incidence by age, these differences were maintained both in those over 65 years of age and in those under 65 years of age (2.17% vs. 0.28%; 0.28% vs. 0.18% respectively). Discussion: Therefore, a high incidence of cancer in patients with the first episode of AF was observed (the annual incidence of 2.45% after the onset of AF is 6.1 times that of the general population). After the evaluation of patients with AF in their first detected episode, surveillance of the appearance of cancer should be considered in clinical practice. <p
