In structural family therapy, normal family development is not characterized by a lack of problems, but instead by families’ having developed a functional structure for dealing with their problems. Whereas, in dialectical behavioral therapy normal family development can be characterized by having a supportive and validating environment, where all family members feel a sense of acceptance and validation for who they are and where they are in life. The clinical case conceptualization highlights the importance of conceptualizing how change occurs within a therapeutic setting. In the current case study, the couple did not only experience high-conflict, but there were also issues of substance use, health issues, and other complicating factors. Clinicians should view their clients holistically and tailor their treatment to fit their unique needs. In this framework, change occurs within the family unit, by accepting each member as they are, while at the same time working together to change maladaptive familial structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=couples" title="couples">couples</a>, <a href="https://publications.waset.org/abstracts/search?q=dialectical%20behavior%20therapy" title=" dialectical behavior therapy"> dialectical behavior therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=high-conflict" title=" high-conflict"> high-conflict</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20family%20therapy" title=" structural family therapy"> structural family therapy</a> </p> <a href="https://publications.waset.org/abstracts/92108/use-of-structural-family-therapy-and-dialectical-behavior-therapy-with-high-conflict-couples" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92108.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">349</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">81</span> Website Evaluation of Travel Agencies Class A in Saudi Arabia and Egypt Using Extended Version of Internet Commerce Adoption Model: A Comparative Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tarek%20Abdel%20Azim%20Ahmed">Tarek Abdel Azim Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Eman%20Sarhan%20Shaker"> Eman Sarhan Shaker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research aims to explore how well the extended model of internet commerce adoption (eMICA) model is often used to determine the extent of internet commerce adoption in the travel agencies sector in both Egypt and Kingdom of Saudi Arabia (KSA). The web content analysis method was used to analyze the level of adoption of Egyptian travel agencies and Saudi travel agencies according to data immensely available on their websites. Therefore, each site was categorized according to the phases and levels proposed. In order to achieve this, 120 websites were evaluated by the two authors over a three-month period, from August to October 2020, and then categorized according to the phases and levels of (eMICA). The results show that there are deficiencies in the application of the eMICA model by both KSA and Egyptian travel agencies, generally, updating their websites, the absence of quality certification, offering secure online payment, virtual tours, and videos using Flash animation. In general, the Egyptian companies slightly outperformed the KSA ones in applying eMICA model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=e-commerce" title="e-commerce">e-commerce</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20marketing" title=" internet marketing"> internet marketing</a>, <a href="https://publications.waset.org/abstracts/search?q=eMICA" title=" eMICA"> eMICA</a>, <a href="https://publications.waset.org/abstracts/search?q=travel%20agencies" title=" travel agencies"> travel agencies</a>, <a href="https://publications.waset.org/abstracts/search?q=websites" title=" websites"> websites</a> </p> <a href="https://publications.waset.org/abstracts/132383/website-evaluation-of-travel-agencies-class-a-in-saudi-arabia-and-egypt-using-extended-version-of-internet-commerce-adoption-model-a-comparative-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132383.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">137</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">80</span> Adomian’s Decomposition Method to Generalized Magneto-Thermoelasticity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamdy%20M.%20Youssef">Hamdy M.

Adomian introduced the decomposition method for solving linear and nonlinear functional equations. This method leads to accurate, computable, approximately convergent solutions of linear and nonlinear partial and ordinary differential equations even the equations with variable coefficients. This paper is dealing with a mathematical model of generalized thermoelasticity of a half-space conducting medium. A magnetic field with constant intensity acts normal to the bounding plane has been assumed. Adomian’s decomposition method has been used to solve the model when the bounding plane is taken to be traction free and thermally loaded by harmonic heating. The numerical results for the temperature increment, the stress, the strain, the displacement, the induced magnetic, and the electric fields have been represented in figures. The magnetic field, the relaxation time, and the angular thermal load have significant effects on all the studied fields. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adomian%E2%80%99s%20decomposition%20method" title="Adomian’s decomposition method">Adomian’s decomposition method</a>, <a href="https://publications.waset.org/abstracts/search?q=magneto-thermoelasticity" title=" magneto-thermoelasticity"> magneto-thermoelasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20conductivity" title=" finite conductivity"> finite conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=iteration%20method" title=" iteration method"> iteration method</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20load" title=" thermal load"> thermal load</a> </p> <a href="https://publications.waset.org/abstracts/97851/adomians-decomposition-method-to-generalized-magneto-thermoelasticity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97851.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">149</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">79</span> Rewriting, Reframing, and Restructuring the Story: A Narrative and Solution Focused Therapy Approach to Family Therapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eman%20Tadros">Eman Tadros</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Solution Focused Therapy sheds a positive light on a client’s problem(s) by instilling hope, focusing on the connection with the client, and describing the problem in a way to display change being possible. Solution focused therapists highlight clients’ positive strengths, reframe what clients say, do, or believe in a positive statement, action, or belief. Narrative Therapy focuses on the stories individuals tell about their past in which shape their current and future lives. Changing the language used aids clients in reevaluating their values and views of themselves, this then constructs a more positive way of thinking about their story. Both therapies are based on treating each client as an individual with a problem rather than that the individual is a problem and being able to give power back to the client. The purpose of these ideologies is to open a client to alternative understandings. This paper displays how clinicians can empower and identify their clients’ positive strengths and resiliency factors. Narrative and Solution-Focused Techniques will be integrated to instill positivity and empowerment in clients. Techniques such as deconstruction, collaboration, complimenting, miracle/exception/scaling questioning will be analyzed and modeled. Furthermore, bridging Solution Focused Therapy and Narrative Therapy gives a voice to unheard client(s). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solution%20focused%20therapy" title="solution focused therapy">solution focused therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=narrative%20therapy" title=" narrative therapy"> narrative therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=empowerment" title=" empowerment"> empowerment</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience" title=" resilience"> resilience</a> </p> <a href="https://publications.waset.org/abstracts/91864/rewriting-reframing-and-restructuring-the-story-a-narrative-and-solution-focused-therapy-approach-to-family-therapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91864.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">238</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">78</span> Biochar as a Strong Adsorbent for Multiple-Metal Removal from Contaminated Water </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eman%20H.%20El-Gamal">Eman H.

In this study, different types of biochar (rice straw 'RSB', corn cob 'CCB', and Jatropha shell 'JSB' were used to evaluate the adsorption capacity of heavy metals removal from multiple-metal solutions (Cu, Mn, Zn, and Cd). Kinetics modeling has been examined to illustrate potential adsorption mechanisms. The results showed that the potential removal of metal is dependent on the metal and biochar types. The adsorption capacity of the biochars followed the order: RSB > JSB > CCB. In general, RSB and JSB biochars presented high potential removal of heavy metals from polluted water, which was higher than 90 and 80% after 2 hrs of contact time for all metals, respectively. According to the kinetics data, the pseudo-second-order model was agreed strongly with Cu, Mn, Zn, and Cd adsorption onto the biochars (R2 ≥ 0.97), indicating the dominance of specific adsorption process, i.e., chemisorption. In conclusion, this study revealed that RSB and JSB biochar have the potential to be a strong adsorbent for multiple-metal removal from wastewater. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=biochar" title=" biochar"> biochar</a>, <a href="https://publications.waset.org/abstracts/search?q=chemisorption" title=" chemisorption"> chemisorption</a>, <a href="https://publications.waset.org/abstracts/search?q=polluted%20water" title=" polluted water"> polluted water</a> </p> <a href="https://publications.waset.org/abstracts/119198/biochar-as-a-strong-adsorbent-for-multiple-metal-removal-from-contaminated-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119198.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">150</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">77</span> Analysis of the Use of a NAO Robot to Improve Social Skills in Children with Autism Spectrum Disorder in Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eman%20Alarfaj">Eman Alarfaj</a>, <a href="https://publications.waset.org/abstracts/search?q=Hissah%20Alabdullatif"> Hissah Alabdullatif</a>, <a href="https://publications.waset.org/abstracts/search?q=Huda%20Alabdullatif"> Huda Alabdullatif</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghazal%20Albakri"> Ghazal Albakri</a>, <a href="https://publications.waset.org/abstracts/search?q=Nor%20Shahriza%20Abdul%20Karim"> Nor Shahriza Abdul Karim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Autism Spectrum Disorder is extensively spread amid children; it affects their social, communication and interactive skills.

In this study, chitosan-coated magnetic nanoparticles (CS-MNPs) for purification of myoglobin were successfully fabricated. First, chitosan (CS) was prepared by a deacetylation reaction during its extraction from shrimp-shell waste. Second, magnetic nanoparticles (MNPs) were synthesised, using the coprecipitation method, from aqueous Fe2+ and Fe3+ salt solutions by the addition of a base under an inert atmosphere, followed by modification of the surface of MNPs with chitosan. The morphology of the formed nanoparticles, which were about 23 nm in average diameter, was observed by transmission electron microscopy (TEM). In addition, nanoparticles were characterised using X-ray diffraction patterns (XRD), which showed the naked magnetic nanoparticles have a spinel structure and the surface modification did not result in phase change of the Fe3O4. The coating of MNPs was also demonstrated by scanning electron microscopy (SEM) analysis, energy dispersive analysis of X-ray spectroscopy (EDAX), and Fourier transform infrared (FT-IR) spectroscopy. The adsorption behaviour of MNPs and CS-MNPs towards myoglobin was investigated. It was found that the difference in adsorption capacity between MNPs and CS-MNPs was larger for CS-MNPs. This result makes CS-MNPs good adsorbents and attractive for using in protein extraction from biological samples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chitosan" title="chitosan">chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20nanoparticles" title=" magnetic nanoparticles"> magnetic nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=coprecipitation" title=" coprecipitation"> coprecipitation</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption "> adsorption </a> </p> <a href="https://publications.waset.org/abstracts/32886/chitosan-magnetic-nanoparticles-and-its-analytical-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32886.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">416</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">75</span> Digital Retinal Images: Background and Damaged Areas Segmentation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eman%20A.%20Gani">Eman A.

Unfortunately, a significant percentage of these images are poor quality that hinders further analysis due to many factors (such as patient movement, inadequate or non-uniform illumination, acquisition angle and retinal pigmentation). The retinal images of poor quality need to be enhanced before the extraction of features and abnormalities. So, the segmentation of retinal image is essential for this purpose, the segmentation is employed to smooth and strengthen image by separating the background and damaged areas from the overall image thus resulting in retinal image enhancement and less processing time. In this paper, methods for segmenting colored retinal image are proposed to improve the quality of retinal image diagnosis. The methods generate two segmentation masks; i.e., background segmentation mask for extracting the background area and poor quality mask for removing the noisy areas from the retinal image. The standard retinal image databases DIARETDB0, DIARETDB1, STARE, DRIVE and some images obtained from ophthalmologists have been used to test the validation of the proposed segmentation technique. Experimental results indicate the introduced methods are effective and can lead to high segmentation accuracy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=retinal%20images" title="retinal images">retinal images</a>, <a href="https://publications.waset.org/abstracts/search?q=fundus%20images" title=" fundus images"> fundus images</a>, <a href="https://publications.waset.org/abstracts/search?q=diabetic%20retinopathy" title=" diabetic retinopathy"> diabetic retinopathy</a>, <a href="https://publications.waset.org/abstracts/search?q=background%20segmentation" title=" background segmentation"> background segmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=damaged%20areas%20segmentation" title=" damaged areas segmentation"> damaged areas segmentation</a> </p> <a href="https://publications.waset.org/abstracts/12289/digital-retinal-images-background-and-damaged-areas-segmentation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12289.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">403</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">74</span> Phenotypical and Genotypical Assessment Techniques for Identification of Some Contagious Mastitis Pathogens</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayman%20El%20Behiry">Ayman El Behiry</a>, <a href="https://publications.waset.org/abstracts/search?q=Rasha%20Nabil%20Zahran"> Rasha Nabil Zahran</a>, <a href="https://publications.waset.org/abstracts/search?q=Reda%20Tarabees"> Reda Tarabees</a>, <a href="https://publications.waset.org/abstracts/search?q=Eman%20Marzouk"> Eman Marzouk</a>, <a href="https://publications.waset.org/abstracts/search?q=Musaad%20Al-Dubaib"> Musaad Al-Dubaib</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mastitis is one of the most economic disease affecting dairy cows worldwide. Its classic diagnosis using bacterial culture and biochemical findings is a difficult and prolonged method. In this research, using of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) permitted identification of different microorganisms with high accuracy and rapidity (only 24 hours for microbial growth and analysis). During the application of MALDI-TOF MS, one hundred twenty strains of Staphylococcus and Streptococcus species isolated from milk of cows affected by clinical and subclinical mastitis were identified, and the results were compared with those obtained by traditional methods as API and VITEK 2 Systems. 37 of totality 39 strains (~95%) of Staphylococcus aureus (S. aureus) were exactly detected by MALDI TOF MS and then confirmed by a nuc-based PCR technique, whereas accurate identification was observed in 100% (50 isolates) of the coagulase negative staphylococci (CNS) and Streptococcus agalactiae (31 isolates). In brief, our results demonstrated that MALDI-TOF MS is a fast and truthful technique which has the capability to replace conventional identification of several bacterial strains usually isolated in clinical laboratories of microbiology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=identification" title="identification">identification</a>, <a href="https://publications.waset.org/abstracts/search?q=mastitis%20pathogens" title=" mastitis pathogens"> mastitis pathogens</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20spectral" title=" mass spectral"> mass spectral</a>, <a href="https://publications.waset.org/abstracts/search?q=phenotypical" title=" phenotypical"> phenotypical</a> </p> <a href="https://publications.waset.org/abstracts/8669/phenotypical-and-genotypical-assessment-techniques-for-identification-of-some-contagious-mastitis-pathogens" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8669.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">332</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">73</span> Characteristics of Phytophthora infestans: The Causal Fungus of Potato Late Blight Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20E.%20Elkorany">A.

The isolates were characterized for mating type and colony morphology. Both A1 and A2 mating types were detected in the isolate collection, however, the A2 constituted 5.8% of the total isolates made while the A1 mating type isolates constituted 91.9%. The self-fertile phenotype was also detected but at a lower percentage of 2.3% of the total isolates. This indicated that Mexico, the probable origin of the disease, is no longer the only place where A2 mating type ever exists. The lumpy phenotype was the only trait observed linked to the A2 mating type isolates on rye A agar medium. The self-fertile isolates, however, exhibited colonies of a waxy appearance with little aerial hyphae and the culture were backed full with oospores. The A1 mating colonies were of smooth white abundant aerial hyphae. The metalaxyl resistant isolates were also detected among the analyzed isolates and constituted 4.6% of the total (86) isolates investigated. The appearance of the A2 mating type outside Mexico and the variation revealed in the population of Phytophthora infestans investigated supported the hypothesis of a second worldwide migration of the fungus from its origin which could constitute a threat to potato cultivation around the world. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Phytophthora%20infestans" title="Phytophthora infestans">Phytophthora infestans</a>, <a href="https://publications.waset.org/abstracts/search?q=potato" title=" potato"> potato</a>, <a href="https://publications.waset.org/abstracts/search?q=Egypt" title=" Egypt"> Egypt</a>, <a href="https://publications.waset.org/abstracts/search?q=fungus" title=" fungus"> fungus</a> </p> <a href="https://publications.waset.org/abstracts/8845/characteristics-of-phytophthora-infestans-the-causal-fungus-of-potato-late-blight-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8845.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">384</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">72</span> Relation between Copper, Lipid Profile, and Cognition in Elderly Jordanians</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eman%20Al-khateeba">Eman Al-khateeba</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebaa%20Al-Zayadneha"> Ebaa Al-Zayadneha</a>, <a href="https://publications.waset.org/abstracts/search?q=Osama%20Al-Dalahmahb"> Osama Al-Dalahmahb</a>, <a href="https://publications.waset.org/abstracts/search?q=Zeinab%20Alawadib"> Zeinab Alawadib</a>, <a href="https://publications.waset.org/abstracts/search?q=Faisal%20Khatiba"> Faisal Khatiba</a>, <a href="https://publications.waset.org/abstracts/search?q=Randa%20Naffaa"> Randa Naffaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Yanal%20Shafagoj"> Yanal Shafagoj</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of the current study was to examine the association of plasma copper and lipid concentrations with changes in cognitive function in elderly Jordanian individuals.

In this study, an activated carbon was prepared from palm trunks by chemical processes. The chemical activation was performed by impregnation of the raw materials after grinding with H3PO4 solution (63%), followed by placing of the sample solution on a muffle furnace at 400ºC for 30 min, and then at 800ºC for 10 min. The morphology of the fabricated material was checked using scanning electron microscopy that showed the rough surfaces on the carbon samples. The use of fabricated activated carbon for removal of eosin dye from aqueous solutions at different contact time, initial dye concentration, pH and adsorbent doses was investigated. The experimental results show that the adsorption process attains equilibrium within 20 min. The adsorption isotherm equilibrium was studied by means of the Langmuir and Freundlich isotherms, and it was found that the data fit the Langmuir isotherm equation with maximum monolayer adsorption capacity of 126.58 mg g-1. The results indicated that the home made activated carbon prepared from palm trunks has the ability to remove eosin dye from aqueous solution and it will be a promising adsorbent for the removal of harmful dyes from waste water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon" title="activated carbon">activated carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=date%20palm%20trunks" title=" date palm trunks"> date palm trunks</a>, <a href="https://publications.waset.org/abstracts/search?q=H3PO4%20activation" title=" H3PO4 activation"> H3PO4 activation</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption"> adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=dye%20removal" title=" dye removal"> dye removal</a>, <a href="https://publications.waset.org/abstracts/search?q=eosin%20dye" title=" eosin dye"> eosin dye</a>, <a href="https://publications.waset.org/abstracts/search?q=isotherm" title=" isotherm"> isotherm</a> </p> <a href="https://publications.waset.org/abstracts/14227/fabrication-of-activated-carbon-from-palm-trunksfor-removal-of-harmful-dyes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14227.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">368</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">70</span> Dynamic Cardiac Mitochondrial Proteome Alterations after Ischemic Preconditioning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelbary%20Prince">Abdelbary Prince</a>, <a href="https://publications.waset.org/abstracts/search?q=Said%20Moussa"> Said Moussa</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyungkyu%20Kim"> Hyungkyu Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Eman%20Gouda"> Eman Gouda</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin%20Han"> Jin Han</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We compared the dynamic alterations of mitochondrial proteome of control, ischemia-reperfusion (IR) and ischemic preconditioned (IPC) rabbit hearts. Using 2-DE, we identified 29 mitochondrial proteins that were differentially expressed in the IR heart compared with the control and IPC hearts. For two of the spots, the expression patterns were confirmed by Western blotting analysis. These proteins included succinate dehydrogenase complex, Acyl-CoA dehydrogenase, carnitine acetyltransferase, dihydrolipoamide dehydrogenase, Atpase, ATP synthase, dihydrolipoamide succinyltransferase, ubiquinol-cytochrome c reductase, translation elongation factor, acyl-CoA dehydrogenase, actin alpha, succinyl-CoA Ligase, dihydrolipoamide S-succinyltransferase, citrate synthase, acetyl-Coenzyme A dehydrogenase, creatine kinase, isocitrate dehydrogenase, pyruvate dehydrogenase, prohibitin, NADH dehydrogenase (ubiquinone) Fe-S protein, enoyl Coenzyme A hydratase, superoxide dismutase [Mn], and 24-kDa subunit of complex I. Interestingly, most of these proteins are associated with the mitochondrial respiratory chain, antioxidant enzyme system, and energy metabolism.

This study explores the potential of blockchain technology in enhancing the security of IoT systems and mitigating these attacks. Blockchain's decentralized and immutable ledger offers significant promise for improving data integrity, transaction transparency, and tamper-proofing. This research develops and implements a blockchain-based IoT architecture and a reference network to simulate real-world scenarios and evaluate a blockchain-integrated intrusion detection system. Performance measures including time delay, security, and resource utilization are used to assess the system's effectiveness, comparing it to conventional IoT networks without blockchain. The results provide valuable insights into the practicality and efficacy of employing blockchain as a security mechanism, shedding light on the trade-offs between speed and security in blockchain deployment for IoT. The study concludes that despite minor increases in time consumption, the security benefits of incorporating blockchain technology into IoT systems outweigh potential drawbacks, demonstrating a significant potential for blockchain in bolstering IoT security. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internet%20of%20things" title="internet of things">internet of things</a>, <a href="https://publications.waset.org/abstracts/search?q=spoofing" title=" spoofing"> spoofing</a>, <a href="https://publications.waset.org/abstracts/search?q=IoT" title=" IoT"> IoT</a>, <a href="https://publications.waset.org/abstracts/search?q=access%20control" title=" access control"> access control</a>, <a href="https://publications.waset.org/abstracts/search?q=blockchain" title=" blockchain"> blockchain</a>, <a href="https://publications.waset.org/abstracts/search?q=raspberry%20pi" title=" raspberry pi"> raspberry pi</a> </p> <a href="https://publications.waset.org/abstracts/177699/enhancing-internet-of-things-security-a-blockchain-based-approach-for-preventing-spoofing-attacks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177699.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">74</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">68</span> Cryptosporidium Parvum oocytic Antigen Induced a Pro-Inflammatory DC Phenotype</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Connick%20K">Connick K</a>, <a href="https://publications.waset.org/abstracts/search?q=Lalor%20R"> Lalor R</a>, <a href="https://publications.waset.org/abstracts/search?q=Murphy%20A"> Murphy A</a>, <a href="https://publications.waset.org/abstracts/search?q=O%E2%80%99Neill%20S.%20M."> O’Neill S.

In immunocompromised hosts, infection Canbe life-threatening as no effective treatments are currently available to control infection. To increase our understanding of the mechanisms that play a role in host-parasite interactions at the level of the immune response, we investigated the effects of Cryptosporidium parvum antigen (CPA) on bone marrow-derived (DCS). Herein we examined cytokine secretion and cell surface marker expression on DCs exposed to CPA. We also measured cytokine production in CD4+ cells co-cultured with CPA primed DCs in the presence of anti-CD3. CPA induced a significant increase in the production of interleukin(IL)-12p40, IL-10, IL-6, and TNF-α by DCs and enhanced the expression of the cell surface markers TLR4, CD80, CD86, and MHC11. CPA primed DC co-cultured in the presence of anti-CD3 with CD4+ T-cells inhibited the secretion of Th2 associated cytokines, notably IL-5 and IL-13, with no effects on the secretions of interferon (IFN)-γ, IL-2, IL-17, and IL-10. These findings support studies in the literature that CPA can induce the full maturation of DCs that subsequently initiate Th1 immune responses critical to the resolution of C. parvum infection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryptosporidium%20parvum" title="cryptosporidium parvum">cryptosporidium parvum</a>, <a href="https://publications.waset.org/abstracts/search?q=dendritic%20cells" title=" dendritic cells"> dendritic cells</a>, <a href="https://publications.waset.org/abstracts/search?q=IL-12%20p70" title=" IL-12 p70"> IL-12 p70</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20surface%20marker" title=" cell surface marker"> cell surface marker</a> </p> <a href="https://publications.waset.org/abstracts/143746/cryptosporidium-parvum-oocytic-antigen-induced-a-pro-inflammatory-dc-phenotype" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143746.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">173</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">67</span> Implementation of Metabolomics in Conjunction with Chemometrics for the Dentification of the Differential Chemical Markers of Different Grades of Sri Lankan White, Green and Black Tea: Camellia Sinenesis L.</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dina%20A.%20Selim">Dina A.

GC–MS analyses of the essential oil resulted in the identification of 68 compounds,; 1,8-cineole (8.9%) and linalool (15.1%) were the main components in the essential oil .The crude extracts were analyzed with TLC plates and revealed several spots under UV light; however the hexane extract exhibited the highest number of spots compared to the other extracts. Hexane extract was selected for GC-MS profile, and the results revealed the presence of several volatile compounds and linalool was the major component with high percentage (11.4 %). Further investigation on the structure elucidation of the bioactive compound (linalool) using IR, GC-MS and NMR techniques compared to authenticated linalool then subjected to purification using preparative and column chromatography. Linalool has been epoxidized using m-chloroperbenzoicacid (mcpba) at room temperature in the presence of florescent lamps to give two cyclic oxygenated products (furan epoxide & pyran epoxide) as a stereospecific product.it is concluded that, oxidation process is enhanced by irradiation to form epoxide derivative, which acts as the precursor of important products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epoxide" title="epoxide">epoxide</a>, <a href="https://publications.waset.org/abstracts/search?q=ginger" title=" ginger"> ginger</a>, <a href="https://publications.waset.org/abstracts/search?q=irradiation" title=" irradiation"> irradiation</a>, <a href="https://publications.waset.org/abstracts/search?q=linalool" title=" linalool"> linalool</a> </p> <a href="https://publications.waset.org/abstracts/38434/the-study-of-natural-synthetic-linalool-isolated-from-ginger-zingiber-officinale-using-photochemical-reactions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38434.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">304</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">65</span> Gum Arabic-Coated Magnetic Nanoparticles for Methylene Blue Removal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eman%20Alzahrani">Eman Alzahrani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Magnetic nanoparticles (MNPs) were fabricated using the chemical co-precipitation method followed by coating the surface of magnetic Fe3O4 nanoparticles with gum arabic (GA). The fabricated magnetic nanoparticles were characterised using transmission electron microscopy (TEM) which showed that the Fe3O4 nanoparticles and GA-MNPs nanoparticles had a mean diameter of 33 nm, and 38 nm, respectively. Scanning electron microscopy (SEM) images showed that the MNPs modified with GA had homogeneous structure and agglomerated. The energy dispersive X-ray spectroscopy (EDAX) spectrum showed strong peaks of Fe and O. X-ray diffraction patterns (XRD) indicated that the naked magnetic nanoparticles were pure Fe3O4 with a spinel structure and the covering of GA did not result in a phase change. The covering of GA on the magnetic nanoparticles was also studied by BET analysis, and Fourier transform infrared spectroscopy. Moreover, the present study reports a fast and simple method for removal and recovery of methylene blue dye (MB) from aqueous solutions by using the synthesised magnetic nanoparticles modified with gum arabic as adsorbent. The experimental results show that the adsorption process attains equilibrium within five minutes. The data fit the Langmuir isotherm equation and the maximum adsorption capacities were 8.77 mg mg-1 and 14.3 mg mg-1 for MNPs and GA-MNPs, respectively. The results indicated that the homemade magnetic nanoparticles were quite efficient for removing MB and will be a promising adsorbent for the removal of harmful dyes from waste-water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fe3O4%20magnetic%20nanoparticles" title="Fe3O4 magnetic nanoparticles">Fe3O4 magnetic nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=gum%20arabic" title=" gum arabic"> gum arabic</a>, <a href="https://publications.waset.org/abstracts/search?q=co-precipitation" title=" co-precipitation"> co-precipitation</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption%20dye" title=" adsorption dye"> adsorption dye</a>, <a href="https://publications.waset.org/abstracts/search?q=methylene%20blue" title=" methylene blue"> methylene blue</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption%20isotherm" title=" adsorption isotherm"> adsorption isotherm</a> </p> <a href="https://publications.waset.org/abstracts/14230/gum-arabic-coated-magnetic-nanoparticles-for-methylene-blue-removal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14230.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">431</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">64</span> Investigating the Impact of Solar Radiation on Electricity Meters’ Accuracy Using A Modified Climatic Chamber</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hala%20M.%20Abdel%20Mageed">Hala M.

In this work, the (MKF-240) climatic chamber has been modified to act as a solar simulator at the Egyptian national institute of standard, NIS. Quartz Tungsten Halogen (QTH) lamps and an Aluminum plate are added to the climatic chamber to realize the solar test conditions. Many experimental trials have been performed to reach the optimum number of lamps needed to fulfil the test requirements and to adjust the best uniform test area. The proposed solar simulator design is capable to produce irradiance up to 1066 W/m2. Its output radiation is controlled by changing the number of illuminated lamps as well as changing the distance between lamps and tested electricity meter. The uniformity of radiation within the simulator has been recognized to be 91.5 % at maximum irradiance. Three samples of electricity meters have been tested under different irradiances, temperatures, and electric loads. The electricity meters’ accuracies have been recorded and analyzedfor eachsample. Moreover, measurement uncertainty contribution has been considered in all tests to get precision value. There were noticeable changes in the accuracies of the electricity meters while exposed to solar radiation, although there were no noticeable distortions of their insulationsand outer surfaces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20radiation" title="solar radiation">solar radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20simulator" title=" solar simulator"> solar simulator</a>, <a href="https://publications.waset.org/abstracts/search?q=climatic%20chamber" title=" climatic chamber"> climatic chamber</a>, <a href="https://publications.waset.org/abstracts/search?q=halogen%20lamp" title=" halogen lamp"> halogen lamp</a>, <a href="https://publications.waset.org/abstracts/search?q=electricity%20meter" title=" electricity meter"> electricity meter</a> </p> <a href="https://publications.waset.org/abstracts/152458/investigating-the-impact-of-solar-radiation-on-electricity-meters-accuracy-using-a-modified-climatic-chamber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152458.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">126</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">63</span> A Review on Control of a Grid Connected Permanent Magnet Synchronous Generator Based Variable Speed Wind Turbine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eman%20M.%20Eissa">Eman M.

One of the challenges pertains to the loss of community identity, which has arisen due to the lack of awareness and unconscious behavior of the residents. An additional issue arises from inadequate site management practices, including the implementation of modern techniques and innovative building materials that are incompatible with structural elements, resulting in the deformation of certain sections of the buildings. The security concerns of the city, along with the ongoing civil conflict, fostered a conducive environment for violations, resulting in the vandalism of certain monuments in the city. However, the degradation of this valuable heritage is mainly attributed to the city's neglect and pollution. The elevated groundwater level resulting from pollution has led to erosion in the building's foundations. Mitigating these negative consequences through strategic interventions and rehabilitation is required to preserve this treasure. In order to assist the local community in recovering from those crises, this paper stated a viable strategy for promoting preservation efforts that aimed at safeguarding the heritage sites while also providing guidance to decision-makers and the local community on how to avoid these crises, preserve, enhance, and recognize the significance of the Libyan heritage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cultural%20heritage" title="cultural heritage">cultural heritage</a>, <a href="https://publications.waset.org/abstracts/search?q=historical%20buildings" title=" historical buildings"> historical buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=Tripoli%E2%80%99s%20old%20city" title=" Tripoli’s old city"> Tripoli’s old city</a>, <a href="https://publications.waset.org/abstracts/search?q=Red%20Castle" title=" Red Castle"> Red Castle</a>, <a href="https://publications.waset.org/abstracts/search?q=crises" title=" crises"> crises</a>, <a href="https://publications.waset.org/abstracts/search?q=preservation" title=" preservation"> preservation</a> </p> <a href="https://publications.waset.org/abstracts/176027/managing-the-architectural-heritage-of-tripoli-libya-the-red-castle-as-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176027.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">125</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">60</span> 128-Multidetector CT for Assessment of Optimal Depth of Electrode Array Insertion in Cochlear Implant Operations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amina%20Sultan">Amina Sultan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Ghonim"> Mohamed Ghonim</a>, <a href="https://publications.waset.org/abstracts/search?q=Eman%20Oweida"> Eman Oweida</a>, <a href="https://publications.waset.org/abstracts/search?q=Aya%20%20Abdelaziz"> Aya Abdelaziz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: To assess the diagnostic reliability of multi-detector CT in pre and post-operative evaluation of cochlear implant candidates. Material and Methods: The study includes 40 patients (18 males and 22 females); mean age 5.6 years. They were classified into two groups: Group A (20 patients): cochlear implant device was Nucleus-22 and Group B (20 patients): the device was MED-EL. Cochlear length (CL) and cochlear height (CH) were measured pre-operatively by 128-multidetector CT. Electrode length (EL) and insertion depth angle (α) were measured post-operatively by MDCT. Results: For Group A mean CL was 9.1 mm ± 0.4 SD; mean CH was 4.1 ± 0.3 SD; mean EL was 18 ± 2.7 SD; mean α angle was 299.05 ± 37 SD. Significant statistical correlation (P < 0.05) was found between preoperative CL and post-operative EL (r²=0.6); as well as EL and α angle (r²=0.7). Group B's mean CL was 9.1 mm ± 0.3 SD; mean CH was 4.1 ± 0.4 SD; mean EL was 27 ± 2.1 SD; mean α angle was 287.6 ± 41.7 SD. Significant statistical correlation was found between CL and EL (r²= 0.6) and α angle (r²=0.5). Also, a strong correlation was found between EL and α angle (r²=0.8). Significant statistical difference was detected between the two devices as regards to the electrode length. Conclusion: Multidetector CT is a reliable tool for preoperative planning and post-operative evaluation of the outcomes of cochlear implant operations. Cochlear length is a valuable prognostic parameter for prediction of the depth of electrode array insertion which can influence criteria of device selection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=angle%20of%20insertion%20%28%CE%B1%20angle%29" title="angle of insertion (α angle)">angle of insertion (α angle)</a>, <a href="https://publications.waset.org/abstracts/search?q=cochlear%20implant%20%28CI%29" title=" cochlear implant (CI)"> cochlear implant (CI)</a>, <a href="https://publications.waset.org/abstracts/search?q=cochlear%20length%20%28CL%29" title=" cochlear length (CL)"> cochlear length (CL)</a>, <a href="https://publications.waset.org/abstracts/search?q=Multidetector%20Computed%20Tomography%20%28MDCT%29" title=" Multidetector Computed Tomography (MDCT)"> Multidetector Computed Tomography (MDCT)</a> </p> <a href="https://publications.waset.org/abstracts/78950/128-multidetector-ct-for-assessment-of-optimal-depth-of-electrode-array-insertion-in-cochlear-implant-operations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78950.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">193</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59</span> The Behavior of Ordinary and Encased Stone Columns in Soft Clay Soil of Egypt: A Finite Element Study </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20F.%20Awad-Allah">Mahmoud F.

Stone columns are commonly used to support structures overlying soft ground soils and surcharged by embankment type loading. Therefore, this paper introduces a wide comparison numerical study between the ordinary stone columns (OSC) versus the geosynthetic encased stone columns (ESC) installed in soft clay soil deposit using finite element method (FEM). Parametric study of an embankment on soft soils reinforced with stone columns is performed using commercial computer program based on the finite element technique (PLAXIS 2D). The investigation will present the influence of the following parameters: diameter of stone columns, stiffness of geosynthetic encasement, embedded depth of stone column from ground level, and the length encasement of the stone column on the consolidation time, vertical settlement, and lateral displacement of soft clay soil formations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title="finite element method">finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=geosynthetic" title=" geosynthetic"> geosynthetic</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20displacement" title=" lateral displacement"> lateral displacement</a>, <a href="https://publications.waset.org/abstracts/search?q=settlement" title=" settlement"> settlement</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20clay" title=" soft clay"> soft clay</a> </p> <a href="https://publications.waset.org/abstracts/94555/the-behavior-of-ordinary-and-encased-stone-columns-in-soft-clay-soil-of-egypt-a-finite-element-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94555.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">210</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">58</span> Development, Optimization, and Validation of a Synchronous Fluorescence Spectroscopic Method with Multivariate Calibration for the Determination of Amlodipine and Olmesartan Implementing: Experimental Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noha%20Ibrahim">Noha Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Eman%20S.%20Elzanfaly"> Eman S.

In Nordic countries, daylight is one of the main considerations within building design, especially in the face of long, lightless winters. A shortage of daylight, contributing to dark and gloomy conditions, necessitates that designs incorporate strong daylight performance. As such, the building in question is designed to capture natural light for varying needs, where studios are located on the North and South façades. The study’s approach presents an analysis of different façade scenarios, where daylight from the North is observed, analyzed and compared with the daylight from the South façade for various design studios in the building. The findings then are correlated with the results of daylight levels from the daylight simulation program (Autodesk Ecotect Analysis) for the investigated studios. The study finds there to be a dramatic difference in daylight nature and levels between the North and South façades, where orientation, obstructions and designed façade fenestrations have major effects on the findings. The study concludes that some of the studios positioned on the North façade do not have a desirable quality of diffused northern light, due to the outside building’s obstructions, area and volume of the studio and the shadow effect of the designed mezzanine floor in the studios. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=daylight%20levels" title="daylight levels">daylight levels</a>, <a href="https://publications.waset.org/abstracts/search?q=educational%20building" title=" educational building"> educational building</a>, <a href="https://publications.waset.org/abstracts/search?q=Fa%C3%A7ade%20fenestration" title=" Façade fenestration"> Façade fenestration</a>, <a href="https://publications.waset.org/abstracts/search?q=overcast%20weather" title=" overcast weather"> overcast weather</a> </p> <a href="https://publications.waset.org/abstracts/108417/analyzing-facade-scenarios-and-daylight-levels-in-the-reid-building-a-reflective-case-study-on-the-designed-daylight-under-overcast-sky" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108417.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">404</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">56</span> A Program Based on Artistic and Musical Activities to Acquire Some Educational Concepts for Children with Learning Difficulties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Amin%20Mousa">Ahmed Amin Mousa</a>, <a href="https://publications.waset.org/abstracts/search?q=Huda%20Mazeed"> Huda Mazeed</a>, <a href="https://publications.waset.org/abstracts/search?q=Eman%20Saad"> Eman Saad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study aims to identify the extent of the effectiveness of the artistic formation program using some types of pastes to reduce the hyperactivity of the kindergarten child.

More specifically, the problem is concerned with finding a permutation that minimizes the sum of distances between itself and a set of three signed permutations. Genomes with equal number of genes but different order can be represented as permutations. In this paper, an algorithm, namely BeamGA median, is proposed that combines a heuristic search approach (local beam) as an initialization step to generate a number of solutions, and then a Genetic Algorithm (GA) is applied in order to refine the solutions, aiming to achieve a better median with the smallest possible reversal distance from the three original permutations. In this approach, any genome rearrangement distance can be applied. In this paper, we use the reversal distance. To the best of our knowledge, the proposed approach was not applied before for solving the median problem. Our approach considers true biological evolution scenario by applying the concept of common intervals during the GA optimization process. This allows us to imitate a true biological behavior and enhance genetic approach time convergence. We were able to handle permutations with a large number of genes, within an acceptable time performance and with same or better accuracy as compared to existing algorithms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=median%20problem" title="median problem">median problem</a>, <a href="https://publications.waset.org/abstracts/search?q=phylogenetic%20tree" title=" phylogenetic tree"> phylogenetic tree</a>, <a href="https://publications.waset.org/abstracts/search?q=permutation" title=" permutation"> permutation</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=beam%20search" title=" beam search"> beam search</a>, <a href="https://publications.waset.org/abstracts/search?q=genome%20rearrangement%20distance" title=" genome rearrangement distance"> genome rearrangement distance</a> </p> <a href="https://publications.waset.org/abstracts/73026/beamga-median-a-hybrid-heuristic-search-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73026.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">265</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">54</span> Endometrial Thickness Cut-Off for Evacuation of Retained Product of Conception</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nambiar%20Ritu">Nambiar Ritu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ban"> Ali Ban</a>, <a href="https://publications.waset.org/abstracts/search?q=Munawar%20Farida"> Munawar Farida</a>, <a href="https://publications.waset.org/abstracts/search?q=Israell%20Imelda"> Israell Imelda</a>, <a href="https://publications.waset.org/abstracts/search?q=T.%20Farouk%20Eman%20Rasheeda"> T.

Background: Studies of conservative management of 1st trimester miscarriage have questioned the need for post miscarriage curettage. Therapeutic decision making with transvaginal scan post miscarriage endometrial thickness in patients clinically thought to be incomplete miscarriage is often not clear. Method: Retrospective analysis of all 1ST trimester ERPC at Al Rahba Hospital from June 2012 to July 2013 was done. Total of 164 patients underwent ERPC. All cases were reviewed for pre-operative USG ET and post ERPC histopathological examination. TVS was done to evaluate the maximum ET of the uterine cavity along the long axis of the uterus and features of retained products was noted. All cases without preoperative USG ET measurement were excluded from the study, therefore only 62 out of 164 cases were included in the study. The patients were divided into three groups: o Group A: have retained products within endometrial cavity. o Group B: endometrial thickness equal or more than 20 mm. o Group C: endometrial thickness equal or less than 19.9 mm. o Post ERPC product was sent for HPE and the results were compared. Transvaginal sonographic findings can be used as a deciding factor in the management of patients with 1st trimester miscarriage who need ERPC. Our proposed cutoff in clinically stable patients requiring ERPC is more than 20 mm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ERPC" title="ERPC">ERPC</a>, <a href="https://publications.waset.org/abstracts/search?q=histopathological%20examination" title=" histopathological examination"> histopathological examination</a>, <a href="https://publications.waset.org/abstracts/search?q=long%20axis%20of%20the%20uterus" title=" long axis of the uterus"> long axis of the uterus</a>, <a href="https://publications.waset.org/abstracts/search?q=USG%20ET" title=" USG ET"> USG ET</a> </p> <a href="https://publications.waset.org/abstracts/16298/endometrial-thickness-cut-off-for-evacuation-of-retained-product-of-conception" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16298.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">216</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">53</span> Trunk and Gluteus-Medius Muscles’ Fatigability during Occupational Standing in Clinical Instructors with Low Back Pain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eman%20A.%20Embaby">Eman A.

Abdallah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Occupational standing is associated with low back pain (LBP) development. Yet, trunk and gluteus-medius muscles’ fatigability has not been extensively studied during occupational standing. This study examined and correlated the rectus abdominus (RA), erector-spinae (ES), external oblique (EO), and gluteus-medius (GM) muscles’ fatigability on both sides while standing in a confined area for 30 min Methods: Median frequency EMG data were collected from 15 female clinical instructors with chronic LBP (group A) and 15 asymptomatic controls (group B) (mean age 29.53±2.4 vs. 29.07±2.4 years, weight 63.6±7 vs. 60±7.8 kg, and height 162.73±4 vs. 162.8±6 cm respectively) using a spectrum analysis program. Data were collected in the first and last 5min of the standing task. Results: Using Mixed three-way ANOVA, group A showed significantly (p<0.05) lower frequencies for the right and left ES, and right GM in the last 5 min and significantly higher frequencies for the left RA in the first and last 5min than group B. In addition, the left ES and right EO, ES and GM in group B showed significantly higher frequencies and the left ES in group A showed significantly lower frequencies in the last 5min compared with the first. Moreover, the right RA showed significantly higher frequencies than the left in the last 5min in group B. Finally, there were significant (p<0.05) correlations among the median frequencies of the tested four muscles on the same side and between both sides in both groups. Discussion/Conclusions: Clinical instructors with LBP are more liable to have higher trunk and gluteus-medius muscle fatigue than asymptomatic individuals. Thus, endurance training for these muscles should be included in the rehabilitation of such patients. <p class="card-text"><strong>Keywords:</strong> <a
