Foot stiffness affects various aspects of walking, such as stability, comfort, and energy expenditure. However, the current prescription process is largely based on trial-and-error, manufacturer recommendations, or clinician judgment, which may not reflect the prosthesis user’s subjective experience or psychophysical sensitivity. Therefore, there is a need for more scientific and technological tools to measure and understand how prosthesis users perceive and prefer different foot stiffness levels, and how this preference relates to clinical outcomes. This review covers how to measure and design lower leg prostheses based on user preference and foot stiffness. It also explores how these factors affect walking outcomes and quality of life, and identifies the current challenges and gaps in this field from a mechanical engineering standpoint. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=perception" title="perception">perception</a>, <a href="https://publications.waset.org/abstracts/search?q=preference" title=" preference"> preference</a>, <a href="https://publications.waset.org/abstracts/search?q=prosthetics" title=" prosthetics"> prosthetics</a>, <a href="https://publications.waset.org/abstracts/search?q=stiffness" title=" stiffness"> stiffness</a> </p> <a href="https://publications.waset.org/abstracts/171957/the-effects-of-prosthetic-leg-stiffness-on-gait-comfort-and-satisfaction-a-review-of-mechanical-engineering-approaches" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171957.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">81</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> Analytical Solution of Blassius Equation Using the Kourosh Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Reza%20Shahnazari">Mohammad Reza Shahnazari</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Kazemi"> Reza Kazemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Saberi"> Ali Saberi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Most of the engineering problems are in nonlinear forms. Nonlinear boundary layer problems defined in infinite intervals contain specific complexities, especially in boundary layer condition conformance. As an example of these nonlinear complex problems, the well-known Blasius equation can be mentioned, which itself is one of the classic boundary layer problems. No analytical solution has been proposed yet for the Blasius equation due to its complexity. In this paper, an analytical method, namely the Kourosh method, based on the singularity perturbation method and the Liao homotopy analysis is utilized to solve the Blasius problem. In this method, an inner solution is developed in the [0,1] interval to expedite the solution convergence. The magnitude of the f ˝(0), as an essential quantity for determining the physical parameters, is directly calculated from the solution of the boundary condition problem. The advantages of this solution are that it does not need any numerical solution, it has a closed form and that its validation is shown in the entire [0,∞] interval. Furthermore, all of the desirable parameters could be extracted through a series of simple analytical operations from the final solution. This solution also satisfies the continuity conditions, which is one of the main contributions of this paper in comparison with most of the other proposed analytical solutions available in the literature. Comparison with numerical solutions reveals that the proposed method is highly accurate and convenient for application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Blasius%20equation" title="Blasius equation">Blasius equation</a>, <a href="https://publications.waset.org/abstracts/search?q=boundary%20layer" title=" boundary layer"> boundary layer</a>, <a href="https://publications.waset.org/abstracts/search?q=Kourosh%20method" title=" Kourosh method"> Kourosh method</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20solution" title=" analytical solution"> analytical solution</a> </p> <a href="https://publications.waset.org/abstracts/49142/analytical-solution-of-blassius-equation-using-the-kourosh-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49142.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">391</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">31</span> Numerical Modelling of Crack Initiation around a Wellbore Due to Explosion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meysam%20Lak">Meysam Lak</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Fatehi%20Marji"> Mohammad Fatehi Marji</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Yarahamdi%20Bafghi"> Alireza Yarahamdi Bafghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abolfazl%20Abdollahipour"> Abolfazl Abdollahipour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A wellbore is a hole that is drilled to aid in the exploration and recovery of natural resources including oil and gas. Occasionally, in order to increase productivity index and porosity of the wellbore and reservoir, the well stimulation methods have been used. Hydraulic fracturing is one of these methods. Moreover, several explosions at the end of the well can stimulate the reservoir and create fractures around it. In this study, crack initiation in rock around the wellbore has been numerically modeled due to explosion. One, two, three, and four pairs of explosion have been set at the end of the wellbore on its wall. After each stage of the explosion, results have been presented and discussed. Results show that this method can initiate and probably propagate several fractures around the wellbore. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crack%20initiation" title="crack initiation">crack initiation</a>, <a href="https://publications.waset.org/abstracts/search?q=explosion" title=" explosion"> explosion</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20difference%20modelling" title=" finite difference modelling"> finite difference modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=well%20productivity" title=" well productivity"> well productivity</a> </p> <a href="https://publications.waset.org/abstracts/84207/numerical-modelling-of-crack-initiation-around-a-wellbore-due-to-explosion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84207.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">291</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Ethnobotanical Survey of Medicinal Plants from Bechar Region, South-West of Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naima%20Fatehi">Naima Fatehi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper reports on 107 medicinal plants, traditionally used in the South-West of Algeria (Bechar region).

Though much progress has been made, the available algorithms do not obtain satisfactory results. The success of these algorithms is rarely above 5%. This work is based on the belief that the main challenge is to come up with “scalable personalization” models. This paper uses an adaptive regularization of inverse singular value decomposition (SVD) that applies adaptive penalization on the singular vectors. The results show far better matching for recommender systems when compared to the ones from the state of the art models in the industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=convex%20optimization" title="convex optimization">convex optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=LASSO" title=" LASSO"> LASSO</a>, <a href="https://publications.waset.org/abstracts/search?q=regression" title=" regression"> regression</a>, <a href="https://publications.waset.org/abstracts/search?q=recommender%20systems" title=" recommender systems"> recommender systems</a>, <a href="https://publications.waset.org/abstracts/search?q=singular%20value%20decomposition" title=" singular value decomposition"> singular value decomposition</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20rank%20approximation" title=" low rank approximation"> low rank approximation</a> </p> <a href="https://publications.waset.org/abstracts/19547/application-of-regularized-low-rank-matrix-factorization-in-personalized-targeting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19547.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">455</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> In-situ Raman Spectroscopy of Flexible Graphene Oxide Films Containing Pt Nanoparticles in The Presense of Atomic Hydrogen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Moafi">Ali Moafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kourosh%20Kalantarzadeh"> Kourosh Kalantarzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20Kaner"> Richard Kaner</a>, <a href="https://publications.waset.org/abstracts/search?q=Parviz%20Parvin"> Parviz Parvin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebrahim%20Asl%20Soleimani"> Ebrahim Asl Soleimani</a>, <a href="https://publications.waset.org/abstracts/search?q=Dougal%20McCulloch"> Dougal McCulloch</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In-situ Raman spectroscopy of flexible graphene-oxide films examined upon exposure to hydrogen gas, air, and synthetic air.

Since, often, there is a long and complicated path that a typical user may venture before taking any (significant) action (such as purchasing goods and services), it is critical to know how each node (media channel) in the path of user has contributed to the final action. In this work, the significance of each media channel is computed using statistical analysis and machine learning techniques. More specifically, “Regularized Singular Value Decomposition”, and “Sparse Principal Component” has been used to compute the significance of each channel toward the final action.

Two types of concrete along with water to cementitious material ratio (W/(C + P)) in 0.45 and 0.4 at the ages of 7, 28 and 90 days and were compared with each other. The effect of these additives on mechanical properties (compressive and tensile strength) and durability has been investigated by Electrical Resistivity (ER) and Rapid Chloride Penetration Test (RCPT) at the ages 28 and 90 days. Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD) revealed that nanoparticles of natural clinoptilolite could improve quality of concrete. As a result of the tests, decrease in penetration of chloride ion and increase electrical resistivity significantly that are appropriate option for controlling of corrosion in reinforced concrete structures but increase of mechanical characteristics is not considerable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ball%20mill" title="ball mill">ball mill</a>, <a href="https://publications.waset.org/abstracts/search?q=durability" title=" durability"> durability</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=nano%20zeolite" title=" nano zeolite"> nano zeolite</a> </p> <a href="https://publications.waset.org/abstracts/50796/manufacturing-of-nano-zeolite-by-planetary-ball-mill-and-investigation-of-the-effects-on-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50796.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">320</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Cross Line of Causality in Childhood Stuttering between Psychology and Neurolinguistics: Systematic Literature Review and Meta-Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sadeq%20Al%20Yaari">Sadeq Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Alkhunayn"> Muhammad Alkhunayn</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayman%20Al%20Yaari"> Ayman Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Montaha%20Al%20Yaari"> Montaha Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Aayah%20Al%20Yaari"> Aayah Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Adham%20Al%20Yaari"> Adham Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Sajedah%20Al%20Yaari"> Sajedah Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatehi%20Eissa"> Fatehi Eissa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Stuttering is a multidimensional disorder that is influenced by different factors. As a result of their un-understanding of the genuine reasons behind stuttering, psychiatrists and Speech and Language Pathologists/Therapists (SLP/Ts) are often unfamiliar with the psychoneurolinguistic characteristics, support needs, and the disability measurement impacting requested rehabilitation of the stuttering population. PubMed, PsycInfo, Web of Science, Scopus, and Google scholar searches, in addition to some unpublished literature, were conducted in this Systematic Literature Review and Meta-analysis (SLR and Meta-analysis) to identify whether stuttering is caused by psychological or neurological reasons. The study concluded that psychological, not neurolinguistic factors were identified as most significant for the causality of childhood stuttering. Stutterers have intact language skills, but impaired ability more to communicate with others than to form letters in the brain or to articulate them. The study recommends research in the future that sheds light on the adult stuttering population often left out of the focus of diagnosis and in need of further exploration vis-a-vis issues they encounter, as well as the possible ways to deal with them psychoneurolinguistically. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=causality" title="causality">causality</a>, <a href="https://publications.waset.org/abstracts/search?q=childhood%20stuttering" title=" childhood stuttering"> childhood stuttering</a>, <a href="https://publications.waset.org/abstracts/search?q=psychology" title=" psychology"> psychology</a>, <a href="https://publications.waset.org/abstracts/search?q=neurolinguistics" title=" neurolinguistics"> neurolinguistics</a>, <a href="https://publications.waset.org/abstracts/search?q=systematic%20literature%20review" title=" systematic literature review"> systematic literature review</a>, <a href="https://publications.waset.org/abstracts/search?q=meta-analysis" title=" meta-analysis"> meta-analysis</a> </p> <a href="https://publications.waset.org/abstracts/186408/cross-line-of-causality-in-childhood-stuttering-between-psychology-and-neurolinguistics-systematic-literature-review-and-meta-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186408.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">23</span> Analysis and Modeling of Stresses and Creeps Resulting from Soil Mechanics in Southern Plains of Kerman Province</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kourosh%20Nazarian">Kourosh Nazarian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many of the engineering materials, such as behavioral metals, have at least a certain level of linear behavior. It means that if the stresses are doubled, the deformations would be also doubled. In fact, these materials have linear elastic properties. Soils do not follow this law, for example, when compressed, soils become gradually tighter. On the surface of the ground, the sand can be easily deformed with a finger, but in high compressive stresses, they gain considerable hardness and strength. This is mainly due to the increase in the forces among the separate particles. Creeps also deform the soils under a constant load over time. Clay and peat soils have creep behavior. As a result of this phenomenon, structures constructed on such soils will continue their collapse over time<span dir="RTL">.</span> In this paper, the researchers analyzed and modeled the stresses and creeps in the southern plains of Kerman province in Iran through library-documentary, quantitative and software techniques, and field survey.

Therefore, this study was conducted to investigate the epidemiological prevalence of diabetes in Afghanistan between 2015 and 2019. Methods: This descriptive cross-sectional study was performed using the information of diabetics registered in the system related to the Ministry of Health of Afghanistan from 2015 to 2019. Eventually, people's information, including age, gender, and place of residence, was entered into STATA software version 12 and analyzed using descriptive statistics tests. Results: The study, which was performed on 49,339 people with diabetes in 34 provinces and 8 regions of Afghanistan, found that most of the women studied were 55.2% (272,311) women and had the highest and lowest prevalence in the region. The order is related to South East and South. The average prevalence of diabetes per 10,000 people is about 62.13. Conclusions: The prevalence of diabetes in Afghanistan over a five-year period in men and women is on the rise, requiring more attention from relevant authorities to improve public health and prevent, control and treat chronic diseases such as diabetes.

Pressure flushing method is an effective way to drain the deposited sediments of the reservoirs through the bottom outlet. So far, several structural methods have been proposed to increase the efficiency of pressure flushing. The aim of this study is to increase the performance of Dendritic Bottomless Extended (DBE) structure on the efficiency of pressurized sediment flushing using submerged vanes. For this purpose, the physical model of the dam reservoir with dimensions of 7.5 m in length, 3.5 m in width, and 1.8 m in height in the hydraulic and water structures research laboratory of Shahid Bahonar University of Kerman was used. In order to investigate the influence of submerged vanes on the performance of DBE structure in pressure flushing, the best arrangement and geometric parameters of the vanes were selected and combined with the DBE structure. The results showed that the submerged vanes significantly increased the performance of the DBE structure so that the volume of the sediment flushing cone with the combination of two structures increased by 3.7 times compared to the DBE structure test. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dendritic%20bottomless%20extended%20structure" title="dendritic bottomless extended structure">dendritic bottomless extended structure</a>, <a href="https://publications.waset.org/abstracts/search?q=flushing%20efficiency" title=" flushing efficiency"> flushing efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=sedimentation" title=" sedimentation"> sedimentation</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment%20flushing" title=" sediment flushing"> sediment flushing</a> </p> <a href="https://publications.waset.org/abstracts/141430/improving-the-performance-of-dbe-structure-in-pressure-flushing-using-submerged-vanes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141430.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">223</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Environmental Study on Urban Disinfection Using an On-site Generation System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V%C3%ADctor%20Mart%C3%ADnez%20del%20Rey">Víctor Martínez del Rey</a>, <a href="https://publications.waset.org/abstracts/search?q=Kourosh%20Nasr%20Esfahani"> Kourosh Nasr Esfahani</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Masoud%20Samani%20Majd"> Amir Masoud Samani Majd</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this experimental study, the behaviors of Mixed Oxidant solution components (MOS) and sodium hypochlorite (HYPO) as the most commonly applied surface disinfectant were compared through the effectiveness of chlorine disinfection as a function of the contact time and residual chlorine. In this regard, the variation of pH, free available chlorine (FAC) concentration, and electric conductivity (EC) of disinfection solutions in different concentrations were monitored over 48 h contact time. In parallel, the plant stress activated by chlorine-based disinfectants was assessed by comparing MOS and HYPO. The elements of pH and EC in the plant-soil and their environmental impacts, spread by disinfection solutions were analyzed through several concentrations of FAC including 500 mg/L, 1000 mg/L, and 5000 mg/L in irrigated water. All the experiments were carried out at the service station of Sant Cugat, Spain. The outcomes indicated lower pH and higher durability of MOS than HYPO at the same concentration of FAC which resulted in promising stability of FAC within MOS. Furthermore, the pH and EC value of plant-soil irrigated by NaOCl solution were higher than that of MOS solution at the same FAC concentration. On-site generation of MOS as a safe chlorination option might be considered an imaginary future of smart cities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=disinfection" title="disinfection">disinfection</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20available%20chlorine" title=" free available chlorine"> free available chlorine</a>, <a href="https://publications.waset.org/abstracts/search?q=on-site%20generation" title=" on-site generation"> on-site generation</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium%20hypochlorite" title=" sodium hypochlorite"> sodium hypochlorite</a> </p> <a href="https://publications.waset.org/abstracts/131151/environmental-study-on-urban-disinfection-using-an-on-site-generation-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131151.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">118</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> The Study of Solar Activity during Sun Eclipse and Its Relation to Earthquake</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hanieh%20Sadat%20Jannesari.%20Rahelehossadat%20Abtahi">Hanieh Sadat Jannesari.

So far, experts have tried to use precursors to identify the earthquake before it occurs in order to alert and save people, a part of which relates to solar activity and earthquakes. The purpose of this article is to investigate solar activity during the solar eclipse as a precursor to pre-earthquake awareness. Information from this article is derived from the Influences and USGS Daily Data Center. During solar activity, electric interactions between the solar wind and the celestial bodies are formed, and then gravitational lenses are formed. If, during this event, there is also an eclipse, the dispersed waves in space (in accordance with the theory of general relativity of Einstein) in contact with plasma-gravitational lenses in space will move in a straight line toward the earth. In addition to forming the focal point, these gravitational lenses reflect the source image either at their focal length or farther away. The image reflected in the earth by ionized particles in the form of energy transmission lines can cause material collapse and earthquakes. In this study, the correlation between solar winds and the celestial bodies during the solar eclipse is about 76% of the location of large earthquakes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earthquake" title="earthquake">earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma-gravitational%20lens" title=" plasma-gravitational lens"> plasma-gravitational lens</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20eclipse" title=" solar eclipse"> solar eclipse</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20spots" title=" solar spots"> solar spots</a> </p> <a href="https://publications.waset.org/abstracts/190332/the-study-of-solar-activity-during-sun-eclipse-and-its-relation-to-earthquake" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190332.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">26</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Using Audio-Visual Aids and Computer-Assisted Language Instruction (CALI) to Overcome Learning Difficulties of Listening in Students of Special Needs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sadeq%20Al%20Yaari">Sadeq Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Alkhunayn"> Muhammad Alkhunayn</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayman%20Al%20Yaari"> Ayman Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Montaha%20Al%20Yaari"> Montaha Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Adham%20Al%20Yaari"> Adham Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Sajedah%20Al%20Yaari"> Sajedah Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatehi%20Eissa"> Fatehi Eissa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background & Aims: Audio-visual aids and computer-aided language instruction (CALI) have been documented to improve receptive skills, namely listening skills, in normal students. The increased listening has been attributed to the understanding of other interlocutors' speech, but recent experiments have suggested that audio-visual aids and CALI should be tested against the listening of students of special needs to see the effects of the former in the latter. This investigation described the effect of audio-visual aids and CALI on the performance of these students. Methods: Pre-and-posttests were administered to 40 students of special needs of both sexes at al-Malādh school for students of special needs aged between 8 and 18 years old. A comparison was held between this group of students and another similar group (control group). Whereas the former group underwent a listening course using audio-visual aids and CALI, the latter studied the same course with the same speech language therapist (SLT) with the classical method. The outcomes of the two tests for the two groups were qualitatively and quantitatively analyzed. Results: Significant improvement in the performance was found in the first group (treatment group) (posttest= 72.45% vs. pre-test= 25.55%) in comparison to the second (control) (posttest= 25.55% vs. pre-test= 23.72%). In comparison to the males’ scores, the scores of females are higher (1487 scores vs. 1411 scores). Suggested results support the necessity of the use of audio-visual aids and CALI in teaching listening at the schools of students of special needs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=listening" title="listening">listening</a>, <a href="https://publications.waset.org/abstracts/search?q=receptive%20skills" title=" receptive skills"> receptive skills</a>, <a href="https://publications.waset.org/abstracts/search?q=audio-visual%20aids" title=" audio-visual aids"> audio-visual aids</a>, <a href="https://publications.waset.org/abstracts/search?q=CALI" title=" CALI"> CALI</a>, <a href="https://publications.waset.org/abstracts/search?q=special%20needs" title=" special needs"> special needs</a> </p> <a href="https://publications.waset.org/abstracts/186406/using-audio-visual-aids-and-computer-assisted-language-instruction-cali-to-overcome-learning-difficulties-of-listening-in-students-of-special-needs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186406.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">48</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> Age and Gender Differences in the Language Deficits of Individuals with Asperger Syndrome (AS) and High Functioning Autism (HFA): Systematic Literature Review (SLR) and Meta-Analysis (MA)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sadeq%20Al%20Yaari">Sadeq Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Alkhunayn"> Muhammad Alkhunayn</a>, <a href="https://publications.waset.org/abstracts/search?q=Montaha%20Al%20Yaari"> Montaha Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayman%20Al%20Yaari"> Ayman Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Aayah%20Al%20Yaari"> Aayah Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Adham%20Al%20Yaari"> Adham Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Sajedah%20Al%20Yaari"> Sajedah Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatehi%20Eissa"> Fatehi Eissa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: In spite of the fact that several language deficits, both internalizing and externalizing, have been documented in comorbidity with Asperger Syndrome (AS) and High Functioning Autism (HFA), there is a paucity of the continuity of these deficits in these individuals’ life span. Furthermore, findings regarding differences in the occurrence of these language deficits both in HFA and AS males and females are mixed. Aims: Systematic Literature Review and meta-analysis (SLR & Meta-analysis) provides a more valid indicator; that is why it has been used here to distinguish HFA and AS individuals in terms of (a) When does language deficits prevails in these individuals’ life and (b) in which gender the prevalence of these language deficits is seen more. Materials and Method: In this SLR & Meta-analysis, PubMed, ScienceDirect, SpringerLink, SAGE journals online, WILEY online library, Google Scholar, CINAHL, EMBASE, Scopus, and ERIC databases in addition to unpublished literature were systematically searched between 1st of January 1980 and 30th of May 2022. Interpretations: Although overall sample sizes were small, the combined results do permit the tentative conclusion that prevalence of language deficits both in AS and HFA children and adults with more prevalence of phonological deficit in HFA male children and pragmatic deficits in AS male children. Further research should be separately undertaken in each linguistic branch to verify the occlusions of this study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high-functioning%20autism" title="high-functioning autism">high-functioning autism</a>, <a href="https://publications.waset.org/abstracts/search?q=Asperger%20syndrome" title=" Asperger syndrome"> Asperger syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=systematic%20literature%20review" title=" systematic literature review"> systematic literature review</a>, <a href="https://publications.waset.org/abstracts/search?q=meta-analysis" title=" meta-analysis"> meta-analysis</a> </p> <a href="https://publications.waset.org/abstracts/186402/age-and-gender-differences-in-the-language-deficits-of-individuals-with-asperger-syndrome-as-and-high-functioning-autism-hfa-systematic-literature-review-slr-and-meta-analysis-ma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186402.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">50</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Genome Characterization and Phylogeny Analysis of Viruses Infected Invertebrates, Parvoviridae Family</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Niloofar%20Fariborzi">Niloofar Fariborzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamzeh%20Alipour"> Hamzeh Alipour</a>, <a href="https://publications.waset.org/abstracts/search?q=Kourosh%20Azizi"> Kourosh Azizi</a>, <a href="https://publications.waset.org/abstracts/search?q=Neda%20Eskandarzade"> Neda Eskandarzade</a>, <a href="https://publications.waset.org/abstracts/search?q=Abozar%20Ghorbani"> Abozar Ghorbani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The family Parvoviridae consists of a large diversity of single-stranded DNA viruses, which cause mild to severe diseases in both vertebrates and invertebrates. The Parvoviridae are classified into three subfamilies: Parvovirinae infect vertebrates, Densovirinae infects invertebrates, while Hamaparovirinae infects both vertebrates and invertebrates. Except for the NS1 region, which is the prime criterion for phylogeny analysis, other parts of the parvoviruses genome, such as UTRs, are diverse even among closely related viruses or within the same genus. It is believed that host switching in parvoviruses may be related to genetic changes in regions other than NS1; therefore, whole-genome screening is valuable for studying parvoviruses' host-virus interactions. The aim of this study was to analyze genome organization and phylogeny of the complete genome sequence of the 132 Paroviridae family members, focusing on viruses that infect invertebrates. The maximum and minimum divergence within each subfamily belonged to Densovirinae and Parvovirinae, respectively. The greatest evolutionary divergence was between Hamaparovirinae and Parvovirinae. Unclassified viruses were mostly from Parovirinae and had the highest divergence to densoviruses and the lowest divergence to Parovirinae viruses. In a phylogenetic tree, all hamparoviruses were found in the center of densoviruses, with the exception of Syngnathid Ichthamaparvovirus 1 (NC_055527), which was positioned between two Parvovirinae members (NC _022089 and NC_038544). The proximity of hamparoviruses members to some densoviruses strengthens the possibility that densoviruses may be the ancestors of hamaparoviruses or vice versa. Therefore, examination and phylogeny analysis of the whole genome is necessary to understand Parvoviridae family host selection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=densoviruses" title="densoviruses">densoviruses</a>, <a href="https://publications.waset.org/abstracts/search?q=parvoviridae" title=" parvoviridae"> parvoviridae</a>, <a href="https://publications.waset.org/abstracts/search?q=bioinformatics" title=" bioinformatics"> bioinformatics</a>, <a href="https://publications.waset.org/abstracts/search?q=phylogeny" title=" phylogeny"> phylogeny</a> </p> <a href="https://publications.waset.org/abstracts/156943/genome-characterization-and-phylogeny-analysis-of-viruses-infected-invertebrates-parvoviridae-family" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156943.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">93</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">15</span> Pragmatic Language Characteristics of Individuals with Asperger Syndrome: Systematic Literature Review and Meta-analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sadeq%20Alyaari">Sadeq Alyaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Alkhunayn"> Muhammad Alkhunayn</a>, <a href="https://publications.waset.org/abstracts/search?q=Montaha%20Al%20Yaari"> Montaha Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayman%20Al%20Yaari"> Ayman Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayah%20Al%20Yaari"> Ayah Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Adham%20Al%20Yaari"> Adham Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Sajedah%20Al%20Yaari"> Sajedah Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatehi%20Eissa"> Fatehi Eissa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction. The purpose of this Systematic Literature Review and Meta-analysis ((SLR & Meta-analysis) was to examine the differences between Asperger syndrome (AS) individuals and typically developing and achieving individuals (TD) regarding language competence and how these differences related to AS individuals’ age and the significance such differences add to our knowledge of understanding their language performance as issues that are still underdiagnosed and ill-treated entities. Methods. The study followed SLR & Meta-analysis protocol and was armed with data of 456 AS subjects and controls (231 and 225, respectively) abstracted from 14 studies that have been collected from different electronic bibliographic databases including web of science, Scopus, EMBASE, Cochrane library, PubMed, PsycInfo and google scholar along with unpublished literature. Results. Outlined results show deterioration in language competence of AS subjects in comparison to TD controls. Such deterioration impairs conversational implicature more than it does conventional maxims of AS individuals’ pragmatic language and has no relationship with their age. Results also show that the difference in intelligence features of the mental reality in the language competence becomes smaller with increasing age and that the difference in representational content features becomes larger. Conclusions. These findings help experts in the field not only predict pragmatic language impairments in AS individuals but also enable AS individuals themselves to decode and/or interpret speech inputs; therefore, perceive the world around them and interact with their community members. Outcomes should be considered to lay out a path for further exploration of genetics, etiology, and response to treatment of all these premises that are currently unsearched in AS individuals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pragmatic%20language%20characteristics" title="pragmatic language characteristics">pragmatic language characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20competence" title=" language competence"> language competence</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20faculty" title=" mental faculty"> mental faculty</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20reality" title=" mental reality"> mental reality</a>, <a href="https://publications.waset.org/abstracts/search?q=features" title=" features"> features</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20performance" title=" language performance"> language performance</a>, <a href="https://publications.waset.org/abstracts/search?q=pragmatics" title=" pragmatics"> pragmatics</a>, <a href="https://publications.waset.org/abstracts/search?q=conventional%20maxims" title=" conventional maxims"> conventional maxims</a> </p> <a href="https://publications.waset.org/abstracts/186310/pragmatic-language-characteristics-of-individuals-with-asperger-syndrome-systematic-literature-review-and-meta-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186310.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">35</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Laser Registration and Supervisory Control of neuroArm Robotic Surgical System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Hoshyarmanesh">Hamidreza Hoshyarmanesh</a>, <a href="https://publications.waset.org/abstracts/search?q=Hosein%20Madieh"> Hosein Madieh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanju%20Lama"> Sanju Lama</a>, <a href="https://publications.waset.org/abstracts/search?q=Yaser%20Maddahi"> Yaser Maddahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Garnette%20R.%20Sutherland"> Garnette R.

Two range-finding algorithms, namely time-of-flight and phase-shift, are evaluated for registration and supervisory control. The time-of-flight approach is implemented in a semi-field experiment to determine the precise position of a tiny retro-reflective moving object. The moving object simulates a surgical tool tip. The tool is a target that would be connected to the neuroArm end-effector during surgery inside the magnet bore of the MR imaging system. In order to apply flight approach, a 905-nm pulsed laser diode and an avalanche photodiode are utilized as the transmitter and receiver, respectively. For the experiment, a high frequency time to digital converter was designed using a field-programmable gate arrays. In the phase-shift approach, a continuous green laser beam with a wavelength of 530 nm was used as the transmitter. Results showed that a positioning error of 0.1 mm occurred when the scanner-target point distance was set in the range of 2.5 to 3 meters. The effectiveness of this non-contact approach exhibited that the method could be employed as an alternative for conventional mechanical registration arm. Furthermore, the approach is not limited by physical contact and extension of joint angles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20laser%20scanner" title="3D laser scanner">3D laser scanner</a>, <a href="https://publications.waset.org/abstracts/search?q=intraoperative%20MR%20imaging" title=" intraoperative MR imaging"> intraoperative MR imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroArm" title=" neuroArm"> neuroArm</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20time%20registration" title=" real time registration"> real time registration</a>, <a href="https://publications.waset.org/abstracts/search?q=robot-assisted%20surgery" title=" robot-assisted surgery"> robot-assisted surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=supervisory%20control" title=" supervisory control"> supervisory control</a> </p> <a href="https://publications.waset.org/abstracts/70477/laser-registration-and-supervisory-control-of-neuroarm-robotic-surgical-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70477.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">286</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Accuracy/Precision Evaluation of Excalibur I: A Neurosurgery-Specific Haptic Hand Controller</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Hoshyarmanesh">Hamidreza Hoshyarmanesh</a>, <a href="https://publications.waset.org/abstracts/search?q=Benjamin%20Durante"> Benjamin Durante</a>, <a href="https://publications.waset.org/abstracts/search?q=Alex%20Irwin"> Alex Irwin</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanju%20Lama"> Sanju Lama</a>, <a href="https://publications.waset.org/abstracts/search?q=Kourosh%20Zareinia"> Kourosh Zareinia</a>, <a href="https://publications.waset.org/abstracts/search?q=Garnette%20R.%20Sutherland"> Garnette R. Sutherland</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study reports on a proposed method to evaluate the accuracy and precision of Excalibur I, a neurosurgery-specific haptic hand controller, designed and developed at Project neuroArm. Having an efficient and successful robot-assisted telesurgery is considerably contingent on how accurate and precise a haptic hand controller (master/local robot) would be able to interpret the kinematic indices of motion, i.e., position and orientation, from the surgeon’s upper limp to the slave/remote robot. A proposed test rig is designed and manufactured according to standard ASTM F2554-10 to determine the accuracy and precision range of Excalibur I at four different locations within its workspace: central workspace, extreme forward, far left and far right. The test rig is metrologically characterized by a coordinate measuring machine (accuracy and repeatability < ± 5 µm). Only the serial linkage of the haptic device is examined due to the use of the Structural Length Index (SLI). The results indicate that accuracy decreases by moving from the workspace central area towards the borders of the workspace. In a comparative study, Excalibur I performs on par with the PHANToM PremiumTM 3.0 and more accurate/precise than the PHANToM PremiumTM 1.5. The error in Cartesian coordinate system shows a dominant component in one direction (δx, δy or δz) for the movements on horizontal, vertical and inclined surfaces. The average error magnitude of three attempts is recorded, considering all three error components. This research is the first promising step to quantify the kinematic performance of Excalibur I. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accuracy" title="accuracy">accuracy</a>, <a href="https://publications.waset.org/abstracts/search?q=advanced%20metrology" title=" advanced metrology"> advanced metrology</a>, <a href="https://publications.waset.org/abstracts/search?q=hand%20controller" title=" hand controller"> hand controller</a>, <a href="https://publications.waset.org/abstracts/search?q=precision" title=" precision"> precision</a>, <a href="https://publications.waset.org/abstracts/search?q=robot-assisted%20surgery" title=" robot-assisted surgery"> robot-assisted surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=tele-operation" title=" tele-operation"> tele-operation</a>, <a href="https://publications.waset.org/abstracts/search?q=workspace" title=" workspace"> workspace</a> </p> <a href="https://publications.waset.org/abstracts/86416/accuracyprecision-evaluation-of-excalibur-i-a-neurosurgery-specific-haptic-hand-controller" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86416.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">336</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Lucilia Sericata Netrin-A: Secreted by Salivary Gland Larvae as a Potential to Neuroregeneration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamzeh%20Alipour">Hamzeh Alipour</a>, <a href="https://publications.waset.org/abstracts/search?q=Masoumeh%20Bagheri"> Masoumeh Bagheri</a>, <a href="https://publications.waset.org/abstracts/search?q=Tahereh%20Karamzadeh"> Tahereh Karamzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Abbasali%20Raz"> Abbasali Raz</a>, <a href="https://publications.waset.org/abstracts/search?q=Kourosh%20Azizi"> Kourosh Azizi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Netrin-A, a protein identified for conducting commissural axons, has a similar role in angiogenesis. In addition, studies have shown that one of the netrin-A receptors is expressed in the growing cells of small capillaries. It will be interesting to study this new group of molecules because their role in wound healing will become clearer in the future due to angiogenesis. The greenbottle blowfly Luciliasericata (L. sericata) larvae are increasingly used in maggot therapy of chronic wounds. This aim of this was the identification of moleculareatures of Netrin-A in L. sericata larvae. Larvae were reared under standard maggotarium conditions. The nucleic acid sequence of L. sericataNetrin-A (LSN-A) was then identified using Rapid Amplification of cDNA Ends (RACE) and Rapid Amplification of Genomic Ends (RAGE). Parts of the Netrin-A gene, including the middle, 3′-, and 5′-ends were identified, TA cloned in pTG19 plasmid, and transferred into DH5ɑ Escherichia coli. Each part was sequenced and assembled using SeqMan software. This gene structure was further subjected to in silico analysis. The DNA of LSN-A was identified to be 2407 bp, while its mRNA sequence was recognized as 2115 bp by Oligo0.7 software. It translated the Netrin-A protein with 704 amino acid residues. Its molecular weight is estimated to be 78.6 kDa. The 3-D structure ofNetrin-A drawn by SWISS-MODEL revealed its similarity to the Netrin-1 of humans with 66.8% identity. The LSN-A protein conduces to repair the myelin membrane in neuronal cells. Ultimately, it can be an effective candidate in neural regeneration and wound healing. Furthermore, our next attempt is to deplore recombinant proteins for use in medical sciences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maggot%20therapy" title="maggot therapy">maggot therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=netrin-A" title=" netrin-A"> netrin-A</a>, <a href="https://publications.waset.org/abstracts/search?q=RACE" title=" RACE"> RACE</a>, <a href="https://publications.waset.org/abstracts/search?q=RAGE" title=" RAGE"> RAGE</a>, <a href="https://publications.waset.org/abstracts/search?q=lucilia%20sericata" title=" lucilia sericata"> lucilia sericata</a> </p> <a href="https://publications.waset.org/abstracts/156855/lucilia-sericata-netrin-a-secreted-by-salivary-gland-larvae-as-a-potential-to-neuroregeneration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156855.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">109</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> The Role of Smart Educational Aids in Learning Listening Among Pupils with Attention and Listening Problems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sadeq%20Al%20Yaari">Sadeq Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Alkhunayn"> Muhammad Alkhunayn</a>, <a href="https://publications.waset.org/abstracts/search?q=Adham%20Al%20Yaari"> Adham Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Aayah%20Al%20Yaari"> Aayah Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Montaha%20Al%20Yaari"> Montaha Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayman%20Al%20Yaari"> Ayman Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Sajedah%20Al%20Yaari"> Sajedah Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatehi%20Eissa"> Fatehi Eissa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The recent rise of smart educational aids and the move away from traditional listening aids are leading to a fundamental shift in the way in which individuals with attention and listening problems (ALP) manipulate listening inputs and/or act appropriately to the spoken information presented to them. A total sample of twenty-six ALP pupils (m=20 and f=6) between 7-12 years old was selected from different strata based on gender, region and school. In the sample size, thirteen (10 males and 3 females) received the treatment in terms of smart classes provided with smart educational aids in a listening course that lasted for four months, while others did not (they studied the same course by the same instructor but in ordinary class). A pretest was administered to assess participants’ levels, and a posttest was given to evaluate their attention and listening comprehension performance, namely in phonetic and phonological tests with sociolinguistic themes that have been designed for this purpose.

However, the pupils have not experienced individual smart audio-visual aids that connect listening to other language receptive and productive skills, which could be the future area of research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smart%20educational%20aids" title="smart educational aids">smart educational aids</a>, <a href="https://publications.waset.org/abstracts/search?q=listening%20attention" title=" listening attention"> listening attention</a>, <a href="https://publications.waset.org/abstracts/search?q=pupils" title=" pupils"> pupils</a>, <a href="https://publications.waset.org/abstracts/search?q=problems" title=" problems"> problems</a> </p> <a href="https://publications.waset.org/abstracts/186311/the-impact-of-smart-educational-aids-in-learning-listening-among-pupils-with-attention-and-listening-problems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186311.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">52</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> The Impact of Smart Educational Aids in Learning Listening Among Pupils with Attention and Listening Problems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sadeq%20Al%20Yaari">Sadeq Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Alkhunayn"> Muhammad Alkhunayn</a>, <a href="https://publications.waset.org/abstracts/search?q=Aayah%20Al%20Yaari"> Aayah Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayman%20Al%20Yaari"> Ayman Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Montaha%20Al%20Yaari"> Montaha Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Sajedah%20Al%20Yaari"> Sajedah Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatehi%20Eissa"> Fatehi Eissa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The recent rise of smart educational aids and the move away from traditional listening aids are leading to a fundamental shift in the way in which individuals with attention and listening problems (ALP) manipulate listening inputs and/or act appropriately to the spoken information presented to them. A total sample of twenty-six ALP pupils (m=20 and f=6) between 7-12 years old was selected from different strata based on gender, region and school. In the sample size, thirteen (10 males and 3 females) received the treatment in terms of smart classes provided with smart educational aids in a listening course that lasted for four month-semester while others did not (they studied the same course by the same instructor but in ordinary class). A pretest was administered to assess participants’ levels, and a posttest was given to evaluate their attention and listening comprehension performance, namely in phonetic and phonological tests with sociolinguistic themes that have been designed for this purpose. Test results were analyzed both psychoneurolinguistically and statistically. Results reveal a remarkable change in pupils’ behavioral listening where scores witnessed a significant difference in the performance of the experimental ALP group in the pretest compared to the posttest (Pupils performed better at the pretest-posttest on phonetics than at the two tests on phonology). It is concluded that smart educational aids designed for listening skills help not only increase the listening command of pupils with ALP to understand what they listen to but also develop their interactive listening capability and, at the same rate, are responsible for increasing concentrated and in-depth listening capacity. Plus, ALP pupils become able to grasp the audio content of text recordings, including educational audio recordings, news, oral stories and tales, views, spiritual/religious text and general knowledge.

The current study planned to ensure that the final design reflects the principles of ecotech architecture in most refugee camps. The design process has taken into account various factors, including flexibility, diversity in the camp space according to the ecotech approach, expandability in the building, spatial hierarchy in the design of camp spaces, and the assignment of territories and space sanctuaries to refugees. It should be noted that this study is not a research-oriented type of study and is only limited to collecting information and making hypotheses and questions related to the plan. The researchers attempted to provide a general summary of similar domestic and foreign examples and examine them in similar conditions using the ecotech architecture. The research method utilized in this study was qualitative. Afterwards, the climate studies of the target area, citing and paying attention to the criteria and points extracted from the theoretical framework, reaching the desired conclusion and examining similar examples were followed. Additionally, placement on the site, compliance with relevant standards and regulations, attention to the content and physical program, and addressing the idea and its evolution in all the details of the plan were presented. The data collection procedure included observation and library studies, and the design method was to determine and recognize the subject and examine similar samples. In conclusion, the principles of theoretical foundations, the design protocols in ecotech architecture and the scope of the study are dealt. Furthermore, the site analysis, the design process and the final plan are presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ecotech%20architecture" title="ecotech architecture">ecotech architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=livable%20city" title=" livable city"> livable city</a>, <a href="https://publications.waset.org/abstracts/search?q=shelter" title=" shelter"> shelter</a>, <a href="https://publications.waset.org/abstracts/search?q=refugee%20camp" title=" refugee camp"> refugee camp</a> </p> <a href="https://publications.waset.org/abstracts/167978/the-design-of-an-afghan-refugee-camp-in-kerman-city-through-ecotech-architecture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167978.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">79</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Tracking the Mind's Mouth: Use of Smart Technology for Effective Teaching of Speaking to Pupils with Developmental Co-ordination Disorder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sadeq%20Al%20Yaari">Sadeq Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Alkhunayn"> Muhammad Alkhunayn</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayah%20Al%20Yaari"> Ayah Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayman%20Al%20Yaari"> Ayman Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Montaha%20Al%20Yaari"> Montaha Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Adham%20Al%20Yaari"> Adham Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Sajedah%20Al%20Yaari"> Sajedah Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatehi%20Eissa"> Fatehi Eissa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Developmental co-ordination disorder (DCD) (also known as dyspraxia) causes a child to speak less well than expected in social conversations. We propose that the smart speaking technology could help improve sound production mechanism at both phonetic and phonological levels, which leads to better articulation of an utterance. The participants are twelve privately beginner pupils aged between 6-12 years old and diagnosed with DCD (apraxia) divided into two groups: Experimental group (n=6) and control group (called apraxic control group) (n=6). A total of fifty typically developing and achieving (TD) pupils participated as control group 2 in both groups and were preassigned into two groups (27 pupils with the treatment group and 23 with the apraxic control group). Weekly quizzes were given to all participants each week for four continuous months and results were analyzed by psychoneurolinguists and a statistician. Although being taught by the same speech-language therapist (SLT), treatment group along with TD groups were taught a full-time speaking course with sociolinguistic themes covering both phonetic and phonological properties. The course lasted for a whole semester whereby smart speaking aids have become dominant while apraxic control group and its TD group were not. Compared with apraxic control group and its TD subgroup, results show obvious changes in speaking behavioral mechanism of the DCD experimental group and its TD subgroup. Improvement could be taken from the scores where the zero marks disappeared in the fourth week (end of the first month of treatment). Good marks (5 +/10) were seen starting from the eighth week and culminating with full marks in the week number 15 of treatment where some participants scored full mark. This study concludes to support the primacy of the smart educational technology for speaking purposes and also shows that such aids can expand the range of academic performance differential categories. Further research is required to evaluate the current demonizing of smart educational aids and weighting more reasonably the relationship specificity that speaking aids can offer to other language skills, as well as their limitations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smart%20educational%20technology" title="smart educational technology">smart educational technology</a>, <a href="https://publications.waset.org/abstracts/search?q=speaking%20aids" title=" speaking aids"> speaking aids</a>, <a href="https://publications.waset.org/abstracts/search?q=pupils%20with%20SCD" title=" pupils with SCD"> pupils with SCD</a>, <a href="https://publications.waset.org/abstracts/search?q=apraxia" title=" apraxia"> apraxia</a> </p> <a href="https://publications.waset.org/abstracts/186315/tracking-the-minds-mouth-use-of-smart-technology-for-effective-teaching-of-speaking-to-pupils-with-developmental-co-ordination-disorder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186315.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">50</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Investigating the Relationship Between Alexithymia and Mobile Phone Addiction Along with the Mediating Role of Anxiety, Stress and Depression: A Path Analysis Study and Structural Model Testing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pouriya%20Darabiyan">Pouriya Darabiyan</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadis%20Nazari"> Hadis Nazari</a>, <a href="https://publications.waset.org/abstracts/search?q=Kourosh%20Zarea"> Kourosh Zarea</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Ghanbari"> Saeed Ghanbari</a>, <a href="https://publications.waset.org/abstracts/search?q=Zeinab%20Raiesifar"> Zeinab Raiesifar</a>, <a href="https://publications.waset.org/abstracts/search?q=Morteza%20Khafaie"> Morteza Khafaie</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanna%20Tuvesson"> Hanna Tuvesson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction Since the beginning of mobile phone addiction, alexithymia, depression, anxiety and stress have been stated as risk factors for Internet addiction, so this study was conducted with the aim of investigating the relationship between Alexithymia and Mobile phone addiction along with the mediating role of anxiety, stress and depression. Materials and methods In this descriptive-analytical and cross-sectional study in 2022, 412 students School of Nursing & Midwifery of Ahvaz Jundishapur University of Medical Sciences were included in the study using available sampling method. Data collection tools were: Demographic Information Questionnaire, Toronto Alexithymia Scale (TAS-20), Depression, Anxiety, Stress Scale (DASS-21) and Mobile Phone Addiction Index (MPAI). Frequency, Pearson correlation coefficient test and linear regression were used to describe and analyze the data. Also, structural equation models and path analysis method were used to investigate the direct and indirect effects as well as the total effect of each dimension of Alexithymia on Mobile phone addiction with the mediating role of stress, depression and anxiety. Statistical analysis was done by SPSS version 22 and Amos version 16 software. Results Alexithymia was a predictive factor for mobile phone addiction. Also, Alexithymia had a positive and significant effect on depression, anxiety and stress. Depression, anxiety and stress had a positive and significant effect on mobile phone addiction. Depression, anxiety and stress variables played the role of a relative mediating variable between Alexithymia and mobile phone addiction. Alexithymia through depression, anxiety and stress also has an indirect effect on Internet addiction. Conclusion Alexithymia is a predictive factor for mobile phone addiction; And the variables of depression, anxiety and stress play the role of a relative mediating variable between Alexithymia and mobile phone addiction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alexithymia" title="alexithymia">alexithymia</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20phone" title=" mobile phone"> mobile phone</a>, <a href="https://publications.waset.org/abstracts/search?q=depression" title=" depression"> depression</a>, <a href="https://publications.waset.org/abstracts/search?q=anxiety" title=" anxiety"> anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a> </p> <a href="https://publications.waset.org/abstracts/163391/investigating-the-relationship-between-alexithymia-and-mobile-phone-addiction-along-with-the-mediating-role-of-anxiety-stress-and-depression-a-path-analysis-study-and-structural-model-testing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163391.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">5</span> Comparison and Effectiveness of Cranial Electrical Stimulation Treatment, Brain Training and Their Combination on Language and Verbal Fluency of Patients with Mild Cognitive Impairment: A Single Subject Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Firoozeh%20Ghazanfari">Firoozeh Ghazanfari</a>, <a href="https://publications.waset.org/abstracts/search?q=Kourosh%20Amraei"> Kourosh Amraei</a>, <a href="https://publications.waset.org/abstracts/search?q=Parisa%20Poorabadi"> Parisa Poorabadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mild cognitive impairment is one of the neurocognitive disorders that go beyond age-related decline in cognitive functions, but in fact, it is not so severe which affects daily activities. This study aimed to investigate and compare the effectiveness of treatment with cranial electrical stimulation, brain training and their double combination on the language and verbal fluency of the elderly with mild cognitive impairment. This is a single-subject method with comparative intervention designs. Four patients with a definitive diagnosis of mild cognitive impairment by a psychiatrist were selected via purposive and convenience sampling method. Addenbrooke's Cognitive Examination Scale (2017) was used to assess language and verbal fluency. Two groups were formed with different order of cranial electrical stimulation treatment, brain training by pencil and paper method and their double combination, and two patients were randomly replaced in each group. The arrangement of the first group included cranial electrical stimulation, brain training, double combination and the second group included double combination, cranial electrical stimulation and brain training, respectively. Treatment plan included: A1, B, A2, C, A3, D, A4, where electrical stimulation treatment was given in ten 30-minutes sessions (5 mA and frequency of 0.5-500 Hz) and brain training in ten 30-minutes sessions. Each baseline lasted four weeks. Patients in first group who first received cranial electrical stimulation treatment showed a higher percentage of improvement in the language and verbal fluency subscale of Addenbrooke's Cognitive Examination in comparison to patients of the second group. Based on the results, it seems that cranial electrical stimulation with its effect on neurotransmitters and brain blood flow, especially in the brain stem, may prepare the brain at the neurochemical and molecular level for a better effectiveness of brain training at the behavioral level, and the selective treatment of electrical stimulation solitude in the first place may be more effective than combining it with paper-pencil brain training. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cranial%20electrical%20stimulation" title="cranial electrical stimulation">cranial electrical stimulation</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment" title=" treatment"> treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=brain%20training" title=" brain training"> brain training</a>, <a href="https://publications.waset.org/abstracts/search?q=verbal%20fluency" title=" verbal fluency"> verbal fluency</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20impairment" title=" cognitive impairment"> cognitive impairment</a> </p> <a href="https://publications.waset.org/abstracts/155741/comparison-and-effectiveness-of-cranial-electrical-stimulation-treatment-brain-training-and-their-combination-on-language-and-verbal-fluency-of-patients-with-mild-cognitive-impairment-a-single-subject-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155741.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">91</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> On the Weightlessness of Vowel Lengthening: Insights from Arabic Dialect of Yemen and Contribution to Psychoneurolinguistics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sadeq%20Al%20Yaari">Sadeq Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Alkhunayn"> Muhammad Alkhunayn</a>, <a href="https://publications.waset.org/abstracts/search?q=Montaha%20Al%20Yaari"> Montaha Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayman%20Al%20Yaari"> Ayman Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Aayah%20Al%20Yaari"> Aayah Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Adham%20Al%20Yaari"> Adham Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Sajedah%20Al%20Yaari"> Sajedah Al Yaari</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatehi%20Eissa"> Fatehi Eissa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: It is well established that lengthening (longer duration) is considered one of the correlates of lexical and phrasal prominence. However, it is unexplored whether the scope of vowel lengthening in the Arabic dialect of Yemen (ADY) is differently affected by educated and/or uneducated speakers from different dialectal backgrounds. Specifically, the research aims to examine whether or not linguistic background acquired through different educational channels makes a difference in the speech of the speaker and how that is reflected in related psychoneurolinguistic impairments. Methods: For the above mentioned purpose, we conducted an articulatory experiment wherein a set of words from ADY were examined in the dialectal speech of thousand and seven hundred Yemeni educated and uneducated speakers aged 19-61 years growing up in five regions of the country: Northern, southern, eastern, western and central and were, accordingly, assigned into five dialectal groups. A seven-minute video clip was shown to the participants, who have been asked to spontaneously describe the scene they had just watched before the researchers linguistically and statistically analyzed recordings to weigh vowel lengthening in the speech of the participants. Results: The results show that vowels (monophthongs and diphthongs) are lengthened by all participants. Unexpectedly, educated and uneducated speakers from northern and central dialects lengthen vowels. Compared with uneducated speakers from the same dialect, educated speakers lengthen fewer vowels in their dialectal speech. Conclusions: These findings support the notion that extensive exposure to dialects on account of standard language can cause changes to the patterns of dialects themselves, and this can be seen in the speech of educated and uneducated speakers of these dialects. Further research is needed to clarify the phonemic distinctive features and frequency of lengthening in other open class systems (i.e., nouns, adjectives, and adverbs). Phonetic and phonological report measures are needed as well as validation of existing measures for assessing phonemic vowel length in the Arabic population in general and Arabic individuals with voice, speech, and language impairments in particular. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vowel%20lengthening" title="vowel
