They have excellent photo-conductivity and high optical absorption to sunlight. Now PIN a-Si:H based solar cells are widely used in power generation modules. However, to improve the performance of these cells further, a better fundamental under-standing of the factors limiting cell performance in the homo junction PIN structure is necessary. In this paper we discuss the sensitivity of light J-V characteristics to various device and material parameters in PIN homo junction solar cells. This work is a numerical simulation of the output parameters of a PIN a-Si:H solar cell under AM1.5 spectrum. These parameters are the short circuit current (Jsc), the open circuit voltage (Voc), the fill factor (FF), the conversion efficiency. The simulation was performed with SCAPS-1D software version 3.3 developed at ELIS in Belgium by Marc Burgelman et al. The obtained results are in agreement with experiment. In addition, the effect of the thickness, doping density, capture cross sections of the gap states and the band microscopic mobilities on the output parameters of the cell are also presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amorphous%20silicon%20p-i-n%20junctions" title="amorphous silicon p-i-n junctions">amorphous silicon p-i-n junctions</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20film" title=" thin film"> thin film</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20cells" title=" solar cells"> solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity" title=" sensitivity"> sensitivity</a> </p> <a href="https://publications.waset.org/abstracts/21840/sensitivity-studies-for-a-pin-homojunction-a-sih-solar-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21840.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">521</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">168</span> Performance Based Road Asset Evaluation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kidus%20Dawit%20Gedamu">Kidus Dawit Gedamu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Addis Ababa City Road Authority is responsible for managing and setting performance evaluation of the city’s road network using the International Roughness Index (IRI). This helps the authority to conduct pavement condition assessments of asphalt roads each year to determine the health status or Level of service (LOS) of the roadway network and plan program improvements such as maintenance, resurfacing and rehabilitation. For a lower IRI limit economical and acceptable maintenance strategy may be selected among a number of maintenance alternatives. The Highway Development and Management (HDM-4) tool can do such measures to help decide which option is the best by evaluating the economic and structural conditions. This paper specifically addresses flexible pavement, including two principal arterial streets under the administration of the Addis Ababa City Roads Authority. The roads include the road from Megenagna Interchange to Ayat Square and from Ayat Square to Tafo RA. First, it was assessed the procedures followed by the city's road authority to develop the appropriate road maintenance strategies. Questionnaire surveys and interviews are used to collect information from the city's road maintenance departments. Second, the project analysis was performed for functional and economic comparison of different maintenance alternatives using HDM-4. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=appropriate%20maintenance%20strategy" title="appropriate maintenance strategy">appropriate maintenance strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20stream" title=" cost stream"> cost stream</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20deterioration" title=" road deterioration"> road deterioration</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance%20alternative" title=" maintenance alternative"> maintenance alternative</a> </p> <a href="https://publications.waset.org/abstracts/184132/performance-based-road-asset-evaluation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184132.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">61</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">167</span> Characterization of the Soils of the Edough Massif (North East Algeria)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Somia%20Lakehal%20Ayat">Somia Lakehal Ayat</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibtissem%20Samai"> Ibtissem Samai</a>, <a href="https://publications.waset.org/abstracts/search?q=Srara%20Lakehal%20Ayat"> Srara Lakehal Ayat</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaima%20Dahmani"> Chaima Dahmani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this work relates to the physicochemical diversity and the characterization of the different types of soils of the edough massif (North East of Algeria) and to the evaluation and characterization of the existing organic matter as well as to the evolution. and the dynamics of the latter, also on its influence on changes in the physical properties of soils. In order to know the soil properties of seraidi forest, we established a stratified sampling plan. The results obtained show that we are in the presence of a great diversity of soils, such as neutral to alkaline, whose adsorbent complex is sufficiently saturated. Also, the presence of limestone offers the soil a fairly significant buffering capacity. In our study region, the texture of the soils is varied between clayey and silty, where it offers medium porosity, there is a strong accumulation of organic matter, therefore soils rich in organic matter.The fractionation of the organic matter of the soils allowed to obtain a very high rate of humification. The soil characteristics of the edough massif (North East of Algeria) are controlled by the contribution of organic matter, which presents a dynamic and an important evolution and which varies with the climatic conditions and the nature and the type of plant formation, and these the latter have a capital and important role in the rate of mineralization of organic matter. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=organic%20matter" title="organic matter">organic matter</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil"> soil</a>, <a href="https://publications.waset.org/abstracts/search?q=foresty" title=" foresty"> foresty</a>, <a href="https://publications.waset.org/abstracts/search?q=diversity" title=" diversity"> diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=mineralization" title=" mineralization"> mineralization</a> </p> <a href="https://publications.waset.org/abstracts/168523/characterization-of-the-soils-of-the-edough-massif-north-east-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168523.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">89</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">166</span> Investigation of NiO/V₂O₅ Powder Composite as Cathode Material for Lithium-Ion Batteries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katia%20Ayouz-Chebout">Katia Ayouz-Chebout</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Boudeffar"> Fatima Boudeffar</a>, <a href="https://publications.waset.org/abstracts/search?q=Maha%20Ayat"> Maha Ayat</a>, <a href="https://publications.waset.org/abstracts/search?q=Malika%20Berouaken"> Malika Berouaken</a>, <a href="https://publications.waset.org/abstracts/search?q=Chafiaa%20Yaddaden"> Chafiaa Yaddaden</a>, <a href="https://publications.waset.org/abstracts/search?q=Saloua%20Merazga"> Saloua Merazga</a>, <a href="https://publications.waset.org/abstracts/search?q=Nouredine%20Gabouze"> Nouredine Gabouze</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Transition metal oxide composites have been widely reported in energy storage and conversion systems.

This paper looks at the excessive use of stone in apartment buildings in Amman and speculates on the existing possibilities of changing the cladding material. By looking at architectural exceptions present in Amman the paper seeks to make the exception, the rule by adding new materials to the architectural library of Amman and in turn, project a series of possible new identities to the existing stone scape. Through distributing a survey, conducting a photographic study on exceptional buildings and shedding light on the historical narrative of stone, the paper highlights the ways in which new finishing materials such as plaster, paint and stone variations could be introduced in an attempt to project a new architectural identity to Amman. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=architectural%20city%20identity" title="architectural city identity">architectural city identity</a>, <a href="https://publications.waset.org/abstracts/search?q=cladding%20materials" title=" cladding materials"> cladding materials</a>, <a href="https://publications.waset.org/abstracts/search?q=fa%C3%A7ade%20architecture" title=" façade architecture"> façade architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20of%20the%20city" title=" image of the city"> image of the city</a> </p> <a href="https://publications.waset.org/abstracts/137728/study-on-the-influence-of-cladding-and-finishing-materials-of-apartment-buildings-on-the-architectural-identity-of-amman" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137728.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">225</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">164</span> Dopamine and Serotonin Levels in Blood Samples of Jordanian Children Who Stutter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mazin%20Alqhazo">Mazin Alqhazo</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayat%20Bani%20Rashaid"> Ayat Bani Rashaid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study examines the levels of dopamine and serotonin in blood samples of children who stutter compared with normal fluent speakers. Blood specimens from 50 children who stutter (6 females, 44 males) and 50 normal children matched age and gender were collected for the purpose of the current study. The concentrations of dopamine and serotonin were measured using the 1100 series high-performance liquid chromatography coupled with ultraviolet detector instrument (HPLC-UV). It was revealed that dopamine level in the blood samples of stuttering group and fluent group was not significant (P = 0.769), whereas the level of serotonin was significantly higher in the blood samples of stuttering group than the blood samples of fluent normal group (P = 0.015). It is concluded that serotonin blockers could be used in future studies to evaluate its role as a medication for the treatment of stuttering. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dopamine" title="dopamine">dopamine</a>, <a href="https://publications.waset.org/abstracts/search?q=serotonin" title=" serotonin"> serotonin</a>, <a href="https://publications.waset.org/abstracts/search?q=stuttering" title=" stuttering"> stuttering</a>, <a href="https://publications.waset.org/abstracts/search?q=fluent%20speakers" title=" fluent speakers"> fluent speakers</a> </p> <a href="https://publications.waset.org/abstracts/112649/dopamine-and-serotonin-levels-in-blood-samples-of-jordanian-children-who-stutter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112649.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">160</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">163</span> Electronic Tongue as an Innovative Non-Destructive Tool for the Quality Monitoring of Fruits</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Ghasemi-Varnamkhasti">Mahdi Ghasemi-Varnamkhasti</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayat%20Mohammad-Razdari"> Ayat Mohammad-Razdari</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyedeh-Hoda%20Yoosefian"> Seyedeh-Hoda Yoosefian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Taste is an important sensory property governing acceptance of products for administration through mouth. The advent of artificial sensorial systems as non-destructive tools able to mimic chemical senses such as those known as electronic tongue (ET) has open a variety of practical applications and new possibilities in many fields where the presence of taste is the phenomenon under control. In recent years, electronic tongue technology opened the possibility to exploit information on taste attributes of fruits providing real time information about quality and ripeness. Electronic tongue systems have received considerable attention in the field of sensor technology during the last two decade because of numerous applications in diverse fields of applied sciences.

Although the specific mechanisms are not yet fully understood, it has been observed that biopolymer agents, such as hyaluronic acid (HA) and alginate (Alg), have the potential to induce transdifferentiation of SSCs. The current work aimed to examine the process of in vitro spermatogenesis and the conversion of mouse testicular cells into hepatocytes and erythrocyte-like cells utilizing the HA-Alg hydrogel. Method: After being extracted from the testes of a 5-day postpartum mouse (5 DPP), the testicular cells were separated into two enzymatic stages and then put into a composite hydrogel containing 0.5% HA and 1% alginate. On days 14 and 28 of culture, the colonies' growth, the cells' viability, and their histology were assessed. Result: Despite observing significant cell proliferation on day 14 and the development of circular-shaped organoids on day 28, it was noted that the organoids generated in the HA-Alg medium tended to maintain their circular morphology on day 28. Notably, the testicular cells underwent transdifferentiation into cell types resembling erythrocytes and hepatocytes. The hepatocyte-like cells exhibited the presence of glycogen and lipid deposits, indicating their hepatocyte-like characteristics. Interestingly, immunostaining analysis revealed the secretion of albumin and the presence of VEGFR on day 14. However, on day 28, albumin expression was not detected, while the expression of Sox9 (a marker for hepatocytes), Vegf, CD34, and C-kit (markers for erythrocytes) showed increased levels in the gene expression evaluation. Conclusion: The present findings indicated that HA-Alg could be a potent and effective agent for the transdifferentiation of testis cells into erythrocyte and hepatocyte-like cells, as recent studies have confirmed the transformation of SSCs into hepatocyte cells during in vitro culture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20culture" title="3D culture">3D culture</a>, <a href="https://publications.waset.org/abstracts/search?q=mouse%20testicular%20cell" title=" mouse testicular cell"> mouse testicular cell</a>, <a href="https://publications.waset.org/abstracts/search?q=hyaluronic%20acid" title=" hyaluronic acid"> hyaluronic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=liver%20organoids" title=" liver organoids"> liver organoids</a> </p> <a href="https://publications.waset.org/abstracts/171962/hyaluronic-acid-alginate-hydrogel-for-the-transdifferentiation-of-testis-cells-into-erythrocyte-and-hepatocyte-like-cells-a-practice-within-an-effective-agent-choice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171962.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">71</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">160</span> Scalable Cloud-Based LEO Satellite Constellation Simulator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karim%20Sobh">Karim Sobh</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20El-Ayat"> Khaled El-Ayat</a>, <a href="https://publications.waset.org/abstracts/search?q=Fady%20Morcos"> Fady Morcos</a>, <a href="https://publications.waset.org/abstracts/search?q=Amr%20El-Kadi"> Amr El-Kadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Distributed applications deployed on LEO satellites and ground stations require substantial communication between different members in a constellation to overcome the earth coverage barriers imposed by GEOs. Applications running on LEO constellations suffer the earth line-of-sight blockage effect. They need adequate lab testing before launching to space. We propose a scalable cloud-based net-work simulation framework to simulate problems created by the earth line-of-sight blockage. The framework utilized cloud IaaS virtual machines to simulate LEO satellites and ground stations distributed software. A factorial ANOVA statistical analysis is conducted to measure simulator overhead on overall communication performance. The results showed a very low simulator communication overhead. Consequently, the simulation framework is proposed as a candidate for testing LEO constellations with distributed software in the lab before space launch. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LEO" title="LEO">LEO</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20computing" title=" cloud computing"> cloud computing</a>, <a href="https://publications.waset.org/abstracts/search?q=constellation" title=" constellation"> constellation</a>, <a href="https://publications.waset.org/abstracts/search?q=satellite" title=" satellite"> satellite</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20simulation" title=" network simulation"> network simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=netfilter" title=" netfilter"> netfilter</a> </p> <a href="https://publications.waset.org/abstracts/23478/scalable-cloud-based-leo-satellite-constellation-simulator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23478.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">386</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">159</span> Equations of Pulse Propagation in Three-Layer Structure of As2S3 Chalcogenide Plasmonic Nano-Waveguides</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leila%20Motamed-Jahromi">Leila Motamed-Jahromi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Hatami"> Mohsen Hatami</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Keshavarz"> Alireza Keshavarz </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research aims at obtaining the equations of pulse propagation in nonlinear plasmonic waveguides created with As<sub>2</sub>S<sub>3</sub> chalcogenide materials.

Neurons were classified based on differences in size and shape of their cell bodies, density of their dendritic trees, morphology and distribution of their appendages. In the spinal trigeminal nucleus of the camel, at least twelve types of neurons were identified. These neurons include, stalked, islets, octubus-like, lobulated, boat-like, pyramidal, multipolar, round, oval and elongated neurons. They have large number of different forms of appendages not only for their dendrites but also for their cell bodies. Neurons with unique large dilatations especially at their dendritic branching points were found. The morphological features of these neurons were described and compared with their counterparts in other species. Finding of large number of neuronal types with different size and shapes and large number of different forms of appendages for cell bodies and dendrites together with the presence of cells with unique features such as large dilated parts for dendrites may indicate to a very complex information processing for pain and temperature at the level of the spinal trigeminal nucleus in the camel that traditionally live in a very hard environment (the desert). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=camel" title="camel">camel</a>, <a href="https://publications.waset.org/abstracts/search?q=golgi" title=" golgi"> golgi</a>, <a href="https://publications.waset.org/abstracts/search?q=neurons" title=" neurons "> neurons </a>, <a href="https://publications.waset.org/abstracts/search?q=spinal%20trigeminal%20nucleus" title=" spinal trigeminal nucleus"> spinal trigeminal nucleus</a> </p> <a href="https://publications.waset.org/abstracts/30990/types-of-neurons-in-the-spinal-trigeminal-nucleus-of-the-camel-brain-golgi-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30990.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">342</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">153</span> Brain Age Prediction Based on Brain Magnetic Resonance Imaging by 3D Convolutional Neural Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leila%20Keshavarz%20Afshar">Leila Keshavarz Afshar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hedieh%20Sajedi"> Hedieh Sajedi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Estimation of biological brain age from MR images is a topic that has been much addressed in recent years due to the importance it attaches to early diagnosis of diseases such as Alzheimer's.

Methods: To this aim, we implemented a software which used data from the internet for facial skin diseases, skin burns, pre-and post-images for plastic surgeries then the post- surgical prediction is done by using K-nearest neighbor (KNN). So we designed and fabricated a smart mirror divided into two parts a screen and a reflective mirror so patient&#39;s pre- and post-appearance will be showed at the same time. Results: We worked on some skin diseases like vitiligo, skin burns and wrinkles. We classified the three degrees of burns using KNN classifier with accuracy 60%. We also succeeded in segmenting the area of vitiligo. Our future work will include working on more skin diseases, classify them and give a prediction for the look after the surgery. Also we will go deeper into facial deformities and plastic surgeries like nose reshaping and face slim down. Conclusion: Our project will give a prediction relates strongly to the real look after surgery and decrease different diagnoses among doctors. Significance: The mirror may have broad societal appeal as it will make the distance between patient&#39;s satisfaction and the medical standards smaller. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=k-nearest%20neighbor%20%28knn%29" title="k-nearest neighbor (knn)">k-nearest neighbor (knn)</a>, <a href="https://publications.waset.org/abstracts/search?q=face%20detection" title=" face detection"> face detection</a>, <a href="https://publications.waset.org/abstracts/search?q=vitiligo" title=" vitiligo"> vitiligo</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20deformity" title=" bone deformity"> bone deformity</a> </p> <a href="https://publications.waset.org/abstracts/108026/pre-operative-tool-for-facial-post-surgical-estimation-and-detection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108026.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">164</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">145</span> Underivatized Amino Acid Analyses Using Liquid Chromatography-Tandem Mass Spectrometry in Scalp Hair of Children with Autism Spectrum Disorder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayat%20Bani%20Rashaid">Ayat Bani Rashaid</a>, <a href="https://publications.waset.org/abstracts/search?q=Zain%20Khasawneh"> Zain Khasawneh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mazin%20Alqhazo"> Mazin Alqhazo</a>, <a href="https://publications.waset.org/abstracts/search?q=Shreen%20Nusair"> Shreen Nusair</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20El-Khateeb"> Mohammad El-Khateeb</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Bashtawi"> Mahmoud Bashtawi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Autism Spectrum disorder (ASD) is a psychiatric disorder with unknown etiology that mainly affects children in the first three years of life. Alterations of amino acid levels are believed to contribute to ASD. The levels of six essential amino acids (methionine, histidine, valine, leucine, threonine, and phenylalanine), five conditional amino acids (proline, tyrosine, glutamine, cysteine, and cystine), and five non-essential amino acids (asparagine, aspartic acid, alanine, serine, and glutamic acid) in hair samples of children with ASD (n = 25) were analyzed and compared to corresponding levels in healthy age-matched controls (n = 25). The results showed that the levels of methionine, alanine, and asparagine were significantly lower in the hair samples of ASD group compared to those of the control group (p &le; 0.05). However, the levels of glutamic acid were significantly higher in the ASD group than the control group (p &le; 0.05). The current findings could contribute towards further understanding of ASD etiology and provide specialists with a hair amino acid profile utilized as a biomarker for early diagnosis of ASD. Such biomarkers could participate in future developments of therapies that reduce ASD-related symptoms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autism%20spectrum%20disorder" title="autism spectrum disorder">autism spectrum disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=amino%20acids" title=" amino acids"> amino acids</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20chromatography-tandem%20mass%20spectrometry" title=" liquid chromatography-tandem mass spectrometry"> liquid chromatography-tandem mass spectrometry</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20hair" title=" human hair"> human hair</a> </p> <a href="https://publications.waset.org/abstracts/128805/underivatized-amino-acid-analyses-using-liquid-chromatography-tandem-mass-spectrometry-in-scalp-hair-of-children-with-autism-spectrum-disorder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128805.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">138</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">144</span> Valorization of Mining Waste (Sand of Djemi Djema) from the Djbel Onk Mine (Eastern Algeria)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rachida%20%20Malaoui">Rachida Malaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Leila%20%20Arabet"> Leila Arabet </a>, <a href="https://publications.waset.org/abstracts/search?q=Asma%20%20Benbouza"> Asma Benbouza </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of mining waste rock as a material for construction is one of the biggest concerns grabbing the attention of many mining countries.

A modification of the policy iteration algorithm is developed to find the optimal policy. A numerical example is presented to compare the optimal policy with the policy considering zero safety stock. <p class="card-text"><strong>Keywords:</strong> <a
