Engelender</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: PINK1 is a mitochondrial kinase mutated in some familial cases of Parkinson’s disease. Down regulation of PINK1 results in abnormal mitochondrial morphology and altered membrane potential. Although PINK1 has a predicted mitochondrial import sequence, it’s cellular, and submitochondrial localization remains unclear, in part because it is rapidly degraded. In this work, we investigated the mechanisms involved in PINK1 degradation and how this may affect PINK1 stability and function, with implications for mitochondrial function in PD. In addition, pharmacological inhibition of proteasome activity was shown to lead to PINK1 accumulation, indicating that PINK1 degradation depends on the ubiquitin-proteasome system (UPS). Methods: Using co-immunoprecipitation assays, we identified E3 ubiquitin ligase SIAH1 as a PINK1-interacting protein in HEK293 cells as well as on rat brain tissues. In addition, we determined the effect of SIAH 1, SIAH2 and Parkin on PINK1 steady-state levels by Western blot analysis, and checked their possibility to ubiquitinate and mediate PINK1 degradation through the proteasome carried out in vivo ubiquitination experiments. Results: We have obtained results showing that SIAH-1 interacts with and ubiquitinates PINK1. The ubiquitination promoted by SIAH-1 leads to the proteasomal degradation of PINK1. We confirmed these findings by knocking down SIAH-1 and observing important accumulation of PINK1 in cells. Besides, we found that SIAH-1 decreases PINK1 steady-state levels but not the E3 ligase Parkin. We also investigated the interaction of SIAH-1 with PINK1 disease mutants and its ability to promote their ubiquitination and degradation. Although, no clear difference in the ability of SIAH-1 to promote the degradation of PINK1 disease mutants was observed. It is possible that dysfunction of proteasomal activity in the disease may lead to the accumulation and aggregation of ubiquitinated PINK1 in patients with PINK1 mutations, with possible implications to the pathogenesis of PD. Conclusions: Here, we demonstrated that SIAH-1 ubiquitinates and promotes the degradation of PINK1. In addition, SIAH-1 represents now a target that may help the improvement of mitophagy in PD. Further investigations needed to understand how mitophagy is regulated by PINK1-SIAH-1 axis to provide targets for future therapeutics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PD" title="PD">PD</a>, <a href="https://publications.waset.org/abstracts/search?q=Parkinson%27s%20disease" title=" Parkinson's disease"> Parkinson's disease</a>, <a href="https://publications.waset.org/abstracts/search?q=PINK1" title=" PINK1"> PINK1</a>, <a href="https://publications.waset.org/abstracts/search?q=PTEN-induced%20kinase1" title=" PTEN-induced kinase1"> PTEN-induced kinase1</a>, <a href="https://publications.waset.org/abstracts/search?q=SIAH" title=" SIAH"> SIAH</a>, <a href="https://publications.waset.org/abstracts/search?q=seven%20in%20absentia%20homolog" title=" seven in absentia homolog"> seven in absentia homolog</a>, <a href="https://publications.waset.org/abstracts/search?q=SN" title=" SN"> SN</a>, <a href="https://publications.waset.org/abstracts/search?q=substantia%20nigra" title=" substantia nigra"> substantia nigra</a> </p> <a href="https://publications.waset.org/abstracts/110954/the-effect-of-siah1-on-pink1-homeostasis-in-parkinson-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110954.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">142</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">123</span> Accounting Information Systems of Kuwaiti Companies: Obstacles and Barriers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haya%20Y%20Alobaid">Haya Y Alobaid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this paper is to identify and discuss the obstacles to the ability of the accounting information systems of Kuwaiti companies to deal with electronic commerce, and then to propose appropriate solutions to overcome the barriers.

This research studies only the second of them; Therefore, we defined it as “The Voiceless Dental- alveolar common augment” (VDACA) to distinguish it from the glottal sound “Hamza”, first, middle, or last, in a noun or in a verb, in Arabic and its equivalent in the Semitic languages. What is meant by “VDACA” is the ta’ that is in addition to the root of the word at the morphological level: the word “voiceless” takes out the voiced sounds that we studied before, and the “dental- alveolar common augment” takes out the laryngeal sound of them, which is the “Hamza”: and the word “common” brings out the uncommon voiceless sounds, which are sīn, shīn, and hā’. The study is limited to the ta' alone among the Arabic sounds, and this title faced a problem in identifying it with the ta'. Because the designation of the ta is not the same in most Semitic languages. Hebrew, for example, has “tav” and is pronounced with the voiced fa (v), which is not in Arabic. It is called different names in other Semitic languages, such as “taw” or “tAu” in old Syriac. And so on. This goes hand in hand with the insistence on distance from the written level and the reference to the phonetic aspect in this study that is closely and closely linked to the morphological level. Therefore, the study is “morphophonemic”. What is meant by Semitic languages in this study are the following: Akkadian, Ugaritic, Hebrew, Syriac, Mandaean, Ge'ez, and Amharic. The problem of the study is the agreement or difference between these languages in the position of that augment, first, middle, or last. And in determining the distinguishing characteristics of each language from the other. As for the study methodology, it is determined by the comparative approach in Semitic languages, which is based on the descriptive approach for each language. The study is divided into an introduction, four sections, and a conclusion: Introduction: It included the subject of the study, its importance, motives, problem, methodology, and division. The first section: VDACA as a non-common phoneme. The second: VDACA as a common phoneme. The third: VDACA as a functional morpheme. The fourth section: Commentary and conclusion with the most important results. The positions of VDACA in Arabic and other Semitic languages, and in nouns and verbs, were limited to first, middle, and last. The research identified the individual addition, which is common with other augments, and the research proved that this augmentation is constant in all Semitic languages, but there are characteristics that distinguish each language from the other. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=voiceless%20-" title="voiceless -">voiceless -</a>, <a href="https://publications.waset.org/abstracts/search?q=dental-%20alveolar" title=" dental- alveolar"> dental- alveolar</a>, <a href="https://publications.waset.org/abstracts/search?q=augment" title=" augment"> augment</a>, <a href="https://publications.waset.org/abstracts/search?q=Arabic%20-%20semitic%20languages" title=" Arabic - semitic languages"> Arabic - semitic languages</a> </p> <a href="https://publications.waset.org/abstracts/173622/the-voiceless-dental-alveolar-common-augment-in-arabic-and-other-semitic-languages-a-morphophonemic-comparison" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173622.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">73</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">121</span> Quality is the Matter of All</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hamza">Mohamed Hamza</a>, <a href="https://publications.waset.org/abstracts/search?q=Alex%20Ohoussou"> Alex Ohoussou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> At JAWDA, our primary focus is on ensuring the satisfaction of our clients worldwide.

The calculated ground state properties are in good agreement with available experimental and theoretical results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DFT" title="DFT">DFT</a>, <a href="https://publications.waset.org/abstracts/search?q=GGA" title=" GGA"> GGA</a>, <a href="https://publications.waset.org/abstracts/search?q=LDA" title=" LDA"> LDA</a>, <a href="https://publications.waset.org/abstracts/search?q=properties%20structurales" title=" properties structurales"> properties structurales</a>, <a href="https://publications.waset.org/abstracts/search?q=ThC" title=" ThC"> ThC</a>, <a href="https://publications.waset.org/abstracts/search?q=ThN" title=" ThN"> ThN</a> </p> <a href="https://publications.waset.org/abstracts/157226/density-functional-dft-study-of-the-structural-and-phase-transition-of-thc-and-thn-lda-vs-gga-computational" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157226.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">98</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">116</span> Green Intellectual Capital and Green Supply Chain Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Ibrahim%20Bu%20Haya">Mohammed Ibrahim Bu Haya</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelmoneim%20Bahyeldin%20Mohamed%20Metwally"> Abdelmoneim Bahyeldin Mohamed Metwally</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper examines the impact of Green Intellectual Capital (GIC) on Green Supply Chain Performance (GSCP). Further, the study examines the moderating role of external pressures (EP) on the relationship between GIC and GSCP. Data were collected from employees working in Egyptian hotels and tourism companies (N= 366). The collected data were analyzed using smart partial least squares (Smart-PLS) software. The current research indicated that there is a positive and significant impact of all GIC components on GSCP. The results also revealed that EP were found to moderate the relationship between GIC and GSCP. The study model was able to explain 63.1% of the variance in GSCP. The findings of this study serve as a pivotal yardstick for guiding corporate policy formulation, offering valuable insights to drive continuous improvements in supply chain management and performance. Furthermore, the research holds substantial implications for managerial strategies by shedding light on the potential of GIC and EP to elevate GSCP. Positioned as one of the initial studies to delve into the moderating role of EP in the relationship between GIC and GSCP, this research offers insights within an emerging market context. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20intellectual%20capital" title="green intellectual capital">green intellectual capital</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20supply%20chain" title=" green supply chain"> green supply chain</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain%20performance" title=" supply chain performance"> supply chain performance</a>, <a href="https://publications.waset.org/abstracts/search?q=external%20pressures" title=" external pressures"> external pressures</a>, <a href="https://publications.waset.org/abstracts/search?q=emerging%20economy" title=" emerging economy"> emerging economy</a>, <a href="https://publications.waset.org/abstracts/search?q=Egypt" title=" Egypt"> Egypt</a> </p> <a href="https://publications.waset.org/abstracts/183650/green-intellectual-capital-and-green-supply-chain-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183650.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">56</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">115</span> Atomistic Study of Structural and Phases Transition of TmAs Semiconductor, Using the FPLMTO Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rekab%20Djabri%20Hamza">Rekab Djabri Hamza</a>, <a href="https://publications.waset.org/abstracts/search?q=Daoud%20Salah"> Daoud Salah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We report first-principles calculations of structural and magnetic properties of TmAs compound in zinc blende(B3) and CsCl(B2), structures employing the density functional theory (DFT) within the local density approximation (LDA).

Patriarchy has an elevated influence on the expression of female sexuality. While women’s sexual experiences are suppressed men are entitled to pleasure themselves according to their desire. The purpose of this study is to explore how the internalization of patriarchy affects women’s sexuality. Similarly, it was investigated how women sexuality is associated with psychological distress. The sample consisted of 100(age 20-40) married women. Participants were selected through a combination of convenient and snowball sampling. Women were asked to provide data regarding patriarchal beliefs, sexual awareness and DAS (depression, anxiety, and stress). Pearson Product Moment Correlation Analyze was conducted to examine the nature of the relationship between patriarchal beliefs, sexual awareness and psychological distress in married women. There is a significant negative relation between sexual awareness and patriarchal beliefs (r=-.391, p<.001). There also lies a significant negative relation between sexual awareness and depression, anxiety, stress (r=-.359, p<.001) (r=.301, p=.002) (r=-.221, p=.027). The results reveal that women with strong patriarchal beliefs have less sexual awareness in terms of sexual consciousness, sexual monitoring, sexual assertiveness and sexual appeal consciousness. Similarly, women with strong patriarchal beliefs and less sexual awareness have high levels of depression, anxiety, and stress. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=female%20sexuality" title="female sexuality">female sexuality</a>, <a href="https://publications.waset.org/abstracts/search?q=patriarchy" title=" patriarchy"> patriarchy</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20distress" title=" psychological distress"> psychological distress</a>, <a href="https://publications.waset.org/abstracts/search?q=sexual%20awareness" title=" sexual awareness"> sexual awareness</a> </p> <a href="https://publications.waset.org/abstracts/57178/womens-sexual-experience-in-pakistan-associations-of-patriarchy-and-psychological-distress" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57178.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">301</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">110</span> Leveraging Unannotated Data to Improve Question Answering for French Contract Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Touila%20Ahmed">Touila Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Elie%20Louis"> Elie Louis</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamza%20Gharbi"> Hamza Gharbi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> State of the art question answering models have recently shown impressive performance especially in a zero-shot setting.

This study shows that the leaves extract of C. latifolia is a good source of important natural antioxidants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=broad-leaved%20quince" title="broad-leaved quince">broad-leaved quince</a>, <a href="https://publications.waset.org/abstracts/search?q=phytochemical" title=" phytochemical"> phytochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-oxidant" title=" anti-oxidant"> anti-oxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=essential%20oils" title=" essential oils"> essential oils</a> </p> <a href="https://publications.waset.org/abstracts/16102/gc-ms-identification-of-two-major-essential-oils-and-their-anti-oxidative-effect-using-dpph-assay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16102.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">504</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">105</span> The Influence of Masculinity and Femininity on Lucid Dreaming and Psychosis Proneness</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anum%20Atiq">Anum Atiq</a>, <a href="https://publications.waset.org/abstracts/search?q=Haya%20Fatimah"> Haya Fatimah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lucid dream is a dream where one is aware that one is dreaming, and they also might be able to influence their dreaming states. Logically, since lucidity cues towards high awareness, it should be negatively associated with proneness to psychosis. However, this association is scarcely studied. Furthermore, although gender differences and similarities in psychopathology have been thoroughly studied, there is room for research in the influence of masculinity and femininity, regardless of one’s sex, on proneness to psychosis. The aim of this study is twofold: 1) We investigated if dream lucidity was negatively associated with psychosis proneness; and 2) We explored the influence of masculinity and femininity on psychosis proneness, over and above the sex. Data were collected by convenience sampling from the undergraduate students enrolled at the University of Management and Technology, Lahore. The sample consisted of 53 students among the age range of 18-26 (men=24, women=29). Masculinity and femininity were measured using the masculinity and femininity subscales of the Personality Attributes Questionnaire. Dream lucidity was measured with The Lucidity and Consciousness in Dreams Scale; and the reality testing sub scale of The Inventory of Personality Organization was used to measure proneness to psychosis. Pearson correlation analysis revealed that psychosis proneness was significantly and negatively correlated with dream lucidity-insight and negative emotion in dreams, but not with other aspects of dream lucidity. Furthermore, masculinity, in both men and women, was positively related with lucid dreaming, and negatively with psychosis proneness. Following this, linear regression analysis showed that psychosis proneness was negatively predicted by masculinity even after controlling for gender. Lucid dreamer and masculinity both have characteristic of independence, emotional control and internal locus of control. Therefore, masculinity makes lucid dreaming less risk of psychosis in both genders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lucid%20dreaming" title="lucid dreaming">lucid dreaming</a>, <a href="https://publications.waset.org/abstracts/search?q=psychosis" title=" psychosis"> psychosis</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a>, <a href="https://publications.waset.org/abstracts/search?q=masculinity%20and%20femininity" title=" masculinity and femininity"> masculinity and femininity</a> </p> <a href="https://publications.waset.org/abstracts/57348/the-influence-of-masculinity-and-femininity-on-lucid-dreaming-and-psychosis-proneness" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57348.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">104</span> Polar Nanoregions in Lead-Free Relaxor Ceramics: Unveiling through Impedance Spectroscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Mesrar">Mohammed Mesrar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamza%20El%20Malki"> Hamza El Malki</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamza%20Mesrar"> Hamza Mesrar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, ceramics of (1-x)(Na0.5Bi0.5)TiO3 x(K0.5 Bi0.5)TiO3 were synthesized through a conventional calcination process (solid-state method) at 1000°C for 4 hours, with x(%) values ranging from 0.0 to 100.

In reality, some IT majors such as computer science and computer engineering receive the software engineering education in a single course which is considered as a big challenged for the instructors and universities. Also, it requires students to gain the most of practical experiences that simulate the real work in software companies. Furthermore, we have noticed that there is no consensus on how, when and what to teach in that introductory course to gain the practical experiences that are required by the software companies. Because all of software engineering disciplines will not fit in just one course, so the course needs reasonable choices in selecting its topics. This arises an important question which is an essential one to ask: Is this course has the ability to formulate a true software engineer that meets the needs of industry? This question arises a big challenge in selecting the appropriate topics. So answering this question is very important for the next undergraduate students. During teaching this course in the curricula, the feedbacks from an undergraduate students and the keynotes of the annual meeting for an advisory committee from industrial side provide a probable answer for the proposed question: it is impossible to build a true software engineer who possesses all the essential elements of software engineering education such teamwork, communications skills, project management skills and contemporary industrial practice from one course and it is impossible to have a one course covering all software engineering topics. Besides the used teaching approach, the author proposes an implemented three supportive ways aiming for mitigating the expected risks and increasing the opportunity to build a true software engineer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=software%20engineering%20course" title="software engineering course">software engineering course</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20engineering%20education" title=" software engineering education"> software engineering education</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20experience" title=" software experience"> software experience</a>, <a href="https://publications.waset.org/abstracts/search?q=supportive%20approach" title=" supportive approach"> supportive approach</a> </p> <a href="https://publications.waset.org/abstracts/36629/an-orphan-software-engineering-course-supportive-ways-toward-a-true-software-engineer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36629.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">359</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">102</span> Ontology-Based Representation of Islamic Rules to Perform Salah</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamza%20Zafar">Hamza Zafar</a>, <a href="https://publications.waset.org/abstracts/search?q=Quratulain%20Rajput"> Quratulain Rajput</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Salah (نماز ) is one of five pillars of Islam and obligatory for every Muslims.

This paper presents an ontology based representation of Islamic rules to perform Salah. The Salah ontology has been built under the guidance of domain expert in light of Quran and Hadith. The ontology consists of basic concepts as well as relationship among concepts and constraints on them. The basic concepts include cleanness, body cover, Salah timing and steps to perform Salah. The SWRL rule language has been used to represent rule to determine whether the Salah performed correctly or it should be repeated. Finally, we evaluate the use of the Salat ontology through user’s example queries using SPARQL queries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=prayer" title="prayer">prayer</a>, <a href="https://publications.waset.org/abstracts/search?q=salah" title=" salah"> salah</a>, <a href="https://publications.waset.org/abstracts/search?q=ontology" title=" ontology"> ontology</a>, <a href="https://publications.waset.org/abstracts/search?q=SPARQL%20queries" title=" SPARQL queries"> SPARQL queries</a>, <a href="https://publications.waset.org/abstracts/search?q=reasoning" title=" reasoning"> reasoning</a> </p> <a href="https://publications.waset.org/abstracts/49552/ontology-based-representation-of-islamic-rules-to-perform-salah" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49552.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">418</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">101</span> Friendship Love Orientation as Predictor of Attachment Style: A Gender Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Sana%20Amin">Maria Sana Amin</a>, <a href="https://publications.waset.org/abstracts/search?q=Anum%20Atiq"> Anum Atiq</a>, <a href="https://publications.waset.org/abstracts/search?q=Haya%20Fatimah"> Haya Fatimah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Secure attachment in childhood creates a healthy love attitude in the adulthood. Child secure attachment develops a positive relation attitude in their adulthood, similarly, anxiety-avoidant attachment develops negative attitude toward relations. The aim of this paper is twofold: 1) We investigate the relationship between Friendship Attitude and Attachment Styles; and 2) explore the impact of gender on Love Attitudes and Attachment styles. Data was collected by convincing sampling among the students of University of Management and Technology age group 18- 25. The sample consists 60 young adults (Male=36, Female =54). The Love Attitudes Scales subscale Storage was used to measure attitudes towards friendship love and The Experiences in Close Relationships-Revised questionnaire was used to measure Adult Attachment Style. The result of Independent T-Test analysis shows that there was no significant difference in anxiety for female and male conditions; t (58) =-.768, p=.446 and avoidance for female and male conditions; t (58) =1.63, p=.108.

In this study we replaced 15% and 25% of cement with Fly ash as the fly ash reduce the value of the pH at the concrete. The main goal of this study was investigated whether bacteria can be used on the soil rather than in the concrete to avoid the challenges and limitations of containing bacteria inside the concrete. This was achieved by incubating cracked cement mortar specimens into fully saturated sterilized and non-sterilized soil. The crack sealing developed in the specimens during the incubation period in both soil conditions were evaluated and compared. Visual inspection, water absorption test, scanning electron microscopy (SEM), and Energy Dispersive X-ray (EDX) were conducted to evaluate the healing process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pH" title="pH">pH</a>, <a href="https://publications.waset.org/abstracts/search?q=calcium%20ions" title=" calcium ions"> calcium ions</a>, <a href="https://publications.waset.org/abstracts/search?q=MICP" title=" MICP"> MICP</a>, <a href="https://publications.waset.org/abstracts/search?q=salinity" title=" salinity"> salinity</a> </p> <a href="https://publications.waset.org/abstracts/154003/sustainable-underground-structures-through-soil-driven-bio-protection-of-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154003.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">116</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">99</span> Design of Single Phase Smart Energy Meter and Grid Tied Inverter for Smart Grid</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamza%20Arif">Hamza Arif</a>, <a href="https://publications.waset.org/abstracts/search?q=Haroon%20Javaid"> Haroon Javaid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Based on hybrid energy concept of smart grid to synchronize and monitor power being generated at the user end.

Naturally, business applications would require the deployment of various RFID systems that are developed by different vendors and use various data formats. This heterogeneity poses a real challenge in developing large-scale IoT systems with RFID as integration is becoming very complex and challenging. Semantic integration is a key approach to deal with this challenge. To do so, ontology for RFID systems need to be developed in order to annotated semantically RFID systems, and hence, facilitate their integration. Accordingly, in this paper, we propose ontology for RFID systems. The proposed ontology can be used to semantically enrich RFID systems, and hence, improve their usage and reasoning. The usage of the proposed ontology is explained through a simple scenario in the health care domain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RFID" title="RFID">RFID</a>, <a href="https://publications.waset.org/abstracts/search?q=semantic%20technology" title=" semantic technology"> semantic technology</a>, <a href="https://publications.waset.org/abstracts/search?q=ontology" title=" ontology"> ontology</a>, <a href="https://publications.waset.org/abstracts/search?q=sparql%20query%20language" title=" sparql query language"> sparql query language</a>, <a href="https://publications.waset.org/abstracts/search?q=heterogeneity" title=" heterogeneity"> heterogeneity</a> </p> <a href="https://publications.waset.org/abstracts/39376/an-ontology-for-semantic-enrichment-of-rfid-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39376.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">471</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">97</span> Pollutant Dispersion in Coastal Waters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sonia%20Ben%20Hamza">Sonia Ben Hamza</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabra%20Habli"> Sabra Habli</a>, <a href="https://publications.waset.org/abstracts/search?q=Nejla%20Mahjoub%20Sa%C3%AFd"> Nejla Mahjoub Saïd</a>, <a href="https://publications.waset.org/abstracts/search?q=Herv%C3%A9%20Bournot"> Hervé Bournot</a>, <a href="https://publications.waset.org/abstracts/search?q=Georges%20Le%20Palec"> Georges Le Palec</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper spots light on the effect of a point source pollution on streams, stemming out from intentional release caused by unconscious facts. The consequences of such contamination on ecosystems are very serious. Accordingly, effective tools are highly demanded in this respect, which enable us to come across an accurate progress of pollutant and anticipate different measures to be applied in order to limit the degradation of the environmental surrounding. In this context, we are eager to model a pollutant dispersion of a free surface flow which is ejected by an outfall sewer of an urban sewerage network in coastal water taking into account the influence of climatic parameters on the spread of pollutant. Numerical results showed that pollutant dispersion is merely due to the presence of vortices and turbulence. Hence, it was realized that the pollutant spread in seawater is strongly correlated with climatic conditions in this region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coastal%20waters" title="coastal waters">coastal waters</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=pollutant%20dispersion" title=" pollutant dispersion"> pollutant dispersion</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulent%20flows" title=" turbulent flows"> turbulent flows</a> </p> <a href="https://publications.waset.org/abstracts/28431/pollutant-dispersion-in-coastal-waters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28431.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">513</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">96</span> An Optimal Steganalysis Based Approach for Embedding Information in Image Cover Media with Security</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahlem%20Fatnassi">Ahlem Fatnassi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamza%20Gharsellaoui"> Hamza Gharsellaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadok%20Bouamama"> Sadok Bouamama</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper deals with the study of interest in the fields of Steganography and Steganalysis.

In this paper, we provide a critical review of the steganalysis algorithms available to analyze the characteristics of an image stego media against the corresponding cover media and understand the process of embedding the information and its detection. We anticipate that this paper can also give a clear picture of the current trends in steganography so that we can develop and improvise appropriate steganalysis algorithms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimization" title="optimization">optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=heuristics%20and%20metaheuristics%20algorithms" title=" heuristics and metaheuristics algorithms"> heuristics and metaheuristics algorithms</a>, <a href="https://publications.waset.org/abstracts/search?q=embedded%20systems" title=" embedded systems"> embedded systems</a>, <a href="https://publications.waset.org/abstracts/search?q=low-power%20consumption" title=" low-power consumption"> low-power consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=steganalysis%20heuristic%20approach" title=" steganalysis heuristic approach"> steganalysis heuristic approach</a> </p> <a href="https://publications.waset.org/abstracts/44034/an-optimal-steganalysis-based-approach-for-embedding-information-in-image-cover-media-with-security" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44034.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">292</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">95</span> A Novel Image Steganography Scheme Based on Mandelbrot Fractal </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adnan%20H.%20M.%20Al-Helali">Adnan H.

Steganography is the art and science of embedding information within electronic media used by common applications and systems. Generally, hiding information of multimedia within images will change some of their properties that may introduce few degradation or unusual characteristics. This paper presents a new image steganography approach for hiding information of multimedia (images, text, and audio) using generated Mandelbrot Fractal image as a cover. The proposed technique has been extensively tested with different images. The results show that the method is a very secure means of hiding and retrieving steganographic information. Experimental results demonstrate that an effective improvement in the values of the Peak Signal to Noise Ratio (PSNR), Mean Square Error (MSE), Normalized Cross Correlation (NCC) and Image Fidelity (IF) over the previous techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fractal%20image" title="fractal image">fractal image</a>,
