J. M. Coetzee's Waiting for the Barbarians elucidates what Primo Levi deems the 'paradoxical' task of testimony: that suffering can only be fully narrated by the sufferer themselves, whose voice and narrative capacity is often foreclosed by the very extent of their trauma. By examining the fictional Magistrate's position as both a reader and translator of history, this paper posits Waiting for the Barbarians as an ethical command against the appropriation of trauma. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ethical%20criticism" title="ethical criticism">ethical criticism</a>, <a href="https://publications.waset.org/abstracts/search?q=limit-experience" title=" limit-experience"> limit-experience</a>, <a href="https://publications.waset.org/abstracts/search?q=postcolonialism" title=" postcolonialism"> postcolonialism</a>, <a href="https://publications.waset.org/abstracts/search?q=psychic%20trauma%20in%20literature" title=" psychic trauma in literature"> psychic trauma in literature</a>, <a href="https://publications.waset.org/abstracts/search?q=testimony" title=" testimony"> testimony</a> </p> <a href="https://publications.waset.org/abstracts/131706/baring-witness-bearing-withness-paradoxes-of-testimony-in-jm-coetzees-waiting-for-the-barbarians" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131706.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">106</span> The Impact of Vocal and Physical Attractiveness on the Employment Interview</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexandra%20Roy">Alexandra Roy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research examines how physical and vocal attractiveness affect impressions of an applicant and whether these impressions are affected by gender or job type. Findings, based on two samples, indicate that individuals with less attractiveness voice and physical appearance were viewed as less suitable job applicants and as possessing more negative characteristics than those others. These negative impressions were pervasive and unaffected by either applicant gender or job type. Specifically, we found that job candidates with an attractive voice or physique were perceived as more extroverted, less agreeable, less conscientious, less trustworthy less competent, less sociable and less recruitable.

Bystanders of this phenomenon can help diminish the incidence of this phenomenon if they engage in pro-social behavior. However, different social-cognitive and affective bystander reactions may surface because of the lack of contextual information and emotional cues in cyberbullying situations. Hence, this study investigated how cyberbullying bystanders’ unpleasant emotions could be related to their personal moral beliefs and their behavioral intentions to cyberbully or defend the victim. It also proposed to investigate how their normative beliefs of perceived severity about cyberbullying behavior could be related to their personal moral beliefs and their behavioral intentions. Three groups of adolescents participated in this study, namely a first of group 402 students (5th – 12th graders; Mage = 13.12; SD = 2.19; 55.7% girls) to compute explorative factorial analyses of the instruments used; a second group of 676 students (5th – 12th graders; Mage = 14.10; SD = 2.74; 55.5% were boys) to run confirmatory factor analyses; and a third group (N = 397; 5th – 12th graders; Mage = 13.88 years; SD = 1.45; 55.5% girls) to perform the main analyses to test the research hypotheses. Self-report measures were used, such as the Personal moral beliefs about cyberbullying behavior questionnaire, the Normative beliefs of perceived severity about cyberbullying behavior questionnaire, the Unpleasant emotions about cyberbullying incidents questionnaires, and the Bystanders’ behavioral intentions in cyberbullying situations questionnaires. Path analysis results revealed that unpleasant emotions were mediators of the relationship between adolescent cyberbullying bystanders’ personal moral beliefs and their intentions to help the victims in cyberbullying situations. Moreover, adolescent cyberbullying bystanders’ normative beliefs of gravity were mediators of the relationship between their personal moral beliefs and their intentions to cyberbully others. These findings provide insights for the development of prevention and intervention programs that promote social and emotional learning strategies as a means to prevent and intervene in cyberbullying. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cyberbullying" title="cyberbullying">cyberbullying</a>, <a href="https://publications.waset.org/abstracts/search?q=normative%20beliefs%20of%20perceived%20severity" title=" normative beliefs of perceived severity"> normative beliefs of perceived severity</a>, <a href="https://publications.waset.org/abstracts/search?q=personal%20moral%20beliefs" title=" personal moral beliefs"> personal moral beliefs</a>, <a href="https://publications.waset.org/abstracts/search?q=unpleasant%20emotions" title=" unpleasant emotions"> unpleasant emotions</a> </p> <a href="https://publications.waset.org/abstracts/142308/how-unpleasant-emotions-morals-and-normative-beliefs-of-severity-relate-to-cyberbullying-intentions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142308.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">103</span> Contemporary Female Composers in Bulgaria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stanimira%20Ntermentzieva">Stanimira Ntermentzieva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gender studies in post-communist Eastern Europe emerged in the early 1990s after the collapse of the communist regime. It can be explained by a series of cultural and political factors. However, Bulgarian female composers’ contribution to Western art music has not been studied. This field shows us some aspects of the impact of globalization on gender issues. This paper outlines the female composers in the establishment of the modern Bulgarian state and society. It is dedicated to the Bulgarian award-winning female composers who studied in Western European and American universities in the 1990s. Many of them migrated to these regions as part of a great migration in which Bulgaria lost 2.3 to three million of its population and strived to modernize Bulgarian music. Nowadays, the Union of Bulgarian Composers has 262 members, but only 19 of them are women. The Grammy-awarded Penka Kouneva (b. 1967) is one of the few female composers in Hollywood. She composed and orchestrated film scores, music for video games and television. Anna-Maria Ravnopolska-Dean (b. 1960) is a Bulgarian/American harpist, arranger, composer, pedagogue and TV host. She wrote pieces for harp and chamber ensembles. Maria Panayotova (b. 1976) studied composition in the USA. Alexandra Fol (b. 1981) and Vania Angelova (b. 1954) work in Canada and are recipients of grants from the Canada Council for the Arts and the Bulgarian Ministry of Culture, among others. Afroditi Katmeridou, born in Bulgaria in 1956 by Greek parents, was the first woman who wrote electroacoustic music. One of the well-known contemporary composers is the British/Bulgarian Dobrinka Tabakova (b. 1980). She moved with her family to the United Kingdom when she was 11 and studied Composition at Guildhall School of Music and Drama in London. Her album String Paths was nominated for a Grammy award. Many female composers made a successful career in EU countries: Albena Petrovic-Vratchanska (Luxemburg), Yuliana Tochkova-Patrouilleau (France), Dariana Kumanova (Italy), Tveta Dimitrova (Austria), Ivajla Kirova (Germany), Alexandra Karastoyanova-Hermentin (Austria) and more. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=balgarian%20music" title="balgarian music">balgarian music</a>, <a href="https://publications.waset.org/abstracts/search?q=female%20composers" title=" female composers"> female composers</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20studies" title=" gender studies"> gender studies</a>, <a href="https://publications.waset.org/abstracts/search?q=western%20art%20music" title=" western art music"> western art music</a>, <a href="https://publications.waset.org/abstracts/search?q=migration" title=" migration"> migration</a> </p> <a href="https://publications.waset.org/abstracts/171069/contemporary-female-composers-in-bulgaria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171069.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">86</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> Hybrid Fermentation System for Improvement of Ergosterol Biosynthesis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexandra%20Tucaliuc">Alexandra Tucaliuc</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandra%20C.%20Blaga"> Alexandra C.

The natural sources of ergosterol are mainly the yeasts (Saccharomyces sp., Candida sp.), but it can be also found in fungus (Claviceps sp.) or plants (orchids). In the yeasts cells, ergosterol is accumulated in membranes, especially in free form in the plasma membrane, but also as esters with fatty acids in membrane lipids. The chemical synthesis of ergosterol does not represent an efficient method for its production, in these circumstances, the most attractive alternative for producing ergosterol at larger-scale remains the aerobic fermentation using S. cerevisiae on glucose or by-products from agriculture of food industry as substrates, in batch or fed-batch operating systems. The aim of this work is to analyze comparatively the influence of aeration efficiency on ergosterol production by S. cerevisiae in batch and fed-batch fermentations, by considering different levels of mixing intensity, aeration rate, and n-dodecane concentration. The effects of the studied factors are quantitatively described by means of the mathematical correlations proposed for each of the two fermentation systems, valid both for the absence and presence of oxygen-vector inside the broth. The experiments were carried out in a laboratory stirred bioreactor, provided with computer-controlled and recorded parameters. n-Dodecane was used as oxygen-vector and the ergosterol content inside the yeasts cells has been considered at the fermentation moment related to the maximum concentration of ergosterol, 9 hrs for batch process and 20 hrs for fed-batch one. Ergosterol biosynthesis is strongly dependent on the dissolved oxygen concentration. The hydrocarbon concentration exhibits a significant influence on ergosterol production mainly by accelerating the oxygen transfer rate. Regardless of n-dodecane addition, by maintaining the glucose concentration at a constant level in the fed-batch process, the amount of ergosterol accumulated into the yeasts cells has been almost tripled. In the presence of hydrocarbon, the ergosterol concentration increased by over 50%. The value of oxygen-vector concentration corresponding to the maximum level of ergosterol depends mainly on biomass concentration, due to its negative influences on broth viscosity and interfacial phenomena of air bubbles blockage through the adsorption of hydrocarbon droplets–yeast cells associations. Therefore, for the batch process, the maximum ergosterol amount was reached for 5% vol. n-dodecane, while for the fed-batch process for 10% vol. hydrocarbon. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioreactors" title="bioreactors">bioreactors</a>, <a href="https://publications.waset.org/abstracts/search?q=ergosterol" title=" ergosterol"> ergosterol</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation" title=" fermentation"> fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=oxygen-vector" title=" oxygen-vector"> oxygen-vector</a> </p> <a href="https://publications.waset.org/abstracts/82746/hybrid-fermentation-system-for-improvement-of-ergosterol-biosynthesis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82746.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">188</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> Public Policy and Sexuality Education for Youth with Disabilities: Impact on Sexual Behavior and Outcomes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexandra%20M.%20Kriofske%20Mainella">Alexandra M.

According to the results presented, PYTHEIA is a valid and reliable scale able to be applied to different target groups for the subjective evaluation of various assistive technology devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rehabilitation" title="rehabilitation">rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=assistive%20technology" title=" assistive technology"> assistive technology</a>, <a href="https://publications.waset.org/abstracts/search?q=assistive%20robots" title=" assistive robots"> assistive robots</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitation%20robots" title=" rehabilitation robots"> rehabilitation robots</a>, <a href="https://publications.waset.org/abstracts/search?q=scale" title=" scale"> scale</a>, <a href="https://publications.waset.org/abstracts/search?q=psychometric%20test" title=" psychometric test"> psychometric test</a>, <a href="https://publications.waset.org/abstracts/search?q=assessment" title=" assessment"> assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=validation" title=" validation"> validation</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20satisfaction" title=" user satisfaction"> user satisfaction</a> </p> <a href="https://publications.waset.org/abstracts/52058/pytheia-a-scale-for-assessing-rehabilitation-and-assistive-robotics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52058.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">312</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> Architectural Heritage of Southern Portugal: Disruptive Practices and Sustainability Plans for its Preservation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patr%C3%ADcia%20Alexandra%20Rodrigues%20Monteiro">Patrícia Alexandra Rodrigues Monteiro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The way modern societies relate with their architectural heritage has become increasingly difficult. This fact is clearer in historic centres of Portuguese peripheral cities or villages, constantly on the balance between its growth needs and the restrictions imposed by the policies for the built heritage preservation. Nowadays, gentrification phenomenon has levelled the differences between architecture, from north to south of the country, under false pretences of modernity and promises of better living conditions for local populations who inhabit historic centres. With this essay, we will address some of the main problems of southern Portugal’s historic centres, reflecting on the concept of sustainability which, also in this context, has acquired an unavoidable relevance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=architecture" title="architecture">architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=art" title=" art"> art</a>, <a href="https://publications.waset.org/abstracts/search?q=heritage" title=" heritage"> heritage</a>, <a href="https://publications.waset.org/abstracts/search?q=portugal" title=" portugal"> portugal</a> </p> <a href="https://publications.waset.org/abstracts/146659/architectural-heritage-of-southern-portugal-disruptive-practices-and-sustainability-plans-for-its-preservation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146659.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">174</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">98</span> Discrimination during a Resume Audit: The Impact of Job Context in Hiring</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexandra%20Roy">Alexandra Roy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Building on literature on cognitive matching and social categorization and using the correspondence testing method, we test the interaction effect of person characteristics (Gender with physical attractiveness) and job context (client contact, industry status, coworker contact).

Galaction</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Amino acids are valuable chemical products used in in human foods, in animal feed additives and in the pharmaceutical field. Recently, there has been a noticeable rise of amino acids utilization throughout the world to include their use as raw materials in the production of various industrial chemicals: oil gelating agents (amino acid-based surfactants) to recover effluent oil in seas and rivers and poly(amino acids), which are attracting attention for biodegradable plastics manufacture. The amino acids can be obtained by biosynthesis or from protein hydrolysis, but their separation from the obtained mixtures can be challenging. In the last decades there has been a continuous interest in developing processes that will improve the selectivity and yield of downstream processing steps. The liquid-liquid extraction of amino acids (dissociated at any pH-value of the aqueous solutions) is possible only by using the reactive extraction technique, mainly with extractants of organophosphoric acid derivatives, high molecular weight amines and crown-ethers. The purpose of this study was to analyse the separation of nine amino acids of acidic character (l-aspartic acid, l-glutamic acid), basic character (l-histidine, l-lysine, l-arginine) and neutral character (l-glycine, l-tryptophan, l-cysteine, l-alanine) by reactive extraction with di-(2-ethylhexyl)phosphoric acid (D2EHPA) dissolved in butyl acetate. The results showed that the separation yield is controlled by the pH value of the aqueous phase: the reactive extraction of amino acids with D2EHPA is possible only if the amino acids exist in aqueous solution in their cationic forms (pH of aqueous phase below the isoeletric point). The studies for individual amino acids indicated the possibility of selectively separate different groups of amino acids with similar acidic properties as a function of aqueous solution pH-value: the maximum yields are reached for a pH domain of 2–3, then strongly decreasing with the pH increase. Thus, for acidic and neutral amino acids, the extraction becomes impossible at the isolelectric point (pHi) and for basic amino acids at a pH value lower than pHi, as a result of the carboxylic group dissociation. From the results obtained for the separation from the mixture of the nine amino acids, at different pH, it can be observed that all amino acids are extracted with different yields, for a pH domain of 1.5–3. Over this interval, the extract contains only the amino acids with neutral and basic character. For pH 5–6, only the neutral amino acids are extracted and for pH > 6 the extraction becomes impossible. Using this technique, the total separation of the following amino acids groups has been performed: neutral amino acids at pH 5–5.5, basic amino acids and l-cysteine at pH 4–4.5, l-histidine at pH 3–3.5 and acidic amino acids at pH 2–2.5. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amino%20acids" title="amino acids">amino acids</a>, <a href="https://publications.waset.org/abstracts/search?q=di-%282-ethylhexyl%29%20phosphoric%20acid" title=" di-(2-ethylhexyl) phosphoric acid"> di-(2-ethylhexyl) phosphoric acid</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20extraction" title=" reactive extraction"> reactive extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=selective%20extraction" title=" selective extraction"> selective extraction</a> </p> <a href="https://publications.waset.org/abstracts/25016/selective-separation-of-amino-acids-by-reactive-extraction-with-di-2-ethylhexyl-phosphoric-acid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25016.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">95</span> Exploring the State of Leadership Effectiveness of Tertiary Institutions in Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ojeka%20Alexandra">Ojeka Alexandra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study investigated the leadership effectiveness of leaders of tertiary institutions in Nigeria.

Europe has been addressing these problems, namely through the Green Deal, with the use of batteries in mobility and energy fields. However, these require the use of critical raw materials, like lithium, which demand is estimated to grow 60 times in the next 30 years. Thus, it is fundamental to promote a circular economy with lithium recovery from secondary resources. These are nowadays key topics, which will be even more relevant in the future, so a new way to approach them is needed and must be encouraged. Therefore, one of our main goals is to analyse two methods of lithium retrieval from secondary sources, bioleaching, and electrodialysis, and assess them regarding their sustainability. The latest results show good efficiency of removal with both methods, even though there are some matrix interferences. Hence, further investment and research are needed in order to make this process sustainable and our society more circular. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lithium" title="lithium">lithium</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20mining" title=" sustainable mining"> sustainable mining</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20license%20to%20operate" title=" social license to operate"> social license to operate</a>, <a href="https://publications.waset.org/abstracts/search?q=bioleaching" title=" bioleaching"> bioleaching</a>, <a href="https://publications.waset.org/abstracts/search?q=electrodialysis" title=" electrodialysis"> electrodialysis</a> </p> <a href="https://publications.waset.org/abstracts/147171/assessing-lithium-recovery-from-secondary-sources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147171.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">130</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">91</span> Predicting the Lifetime of Weathered Polyolefins by Relating Mechanics to Microstructure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marta%20Chiapasco">Marta Chiapasco</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandra%20Porter"> Alexandra Porter</a>, <a href="https://publications.waset.org/abstracts/search?q=Finn%20Giuliani"> Finn Giuliani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Designing polymers with a specific microstructure can affect how the polymer degrades once released in the environment.

The following research investigates the use of a combination of spectroscopy analysis and thermal analysis to study changes of polymers’ amorphous and crystalline phases during degradation, comparing different microstructures of polypropylene and polyethylene. The use of nanoindentation helps study how degradation proceeds across a material by looking at changes in phases, while bulk tensile test describes when the material fails. The first results demonstrate that different microstructures have different degrading rates, with homopolymer having a linear and faster degradation compared to copolymers. The goal is to create materials that degrade at faster rates without releasing microplastics into the environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=degradation" title="degradation">degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoindentation" title=" nanoindentation"> nanoindentation</a>, <a href="https://publications.waset.org/abstracts/search?q=Raman%20spectroscopy" title=" Raman spectroscopy"> Raman spectroscopy</a> </p> <a href="https://publications.waset.org/abstracts/148181/predicting-the-lifetime-of-weathered-polyolefins-by-relating-mechanics-to-microstructure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148181.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">156</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">90</span> Psychological Compatibility of Football Players According to Success Achievement and Failure Avoidance Motivation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Konstantin%20A.%20Bochaver">Konstantin A.

It is not known whether this effect observed due to the presence of nanoceria can be also observed in the presence of cerium in the bioactive glass network. The effect of cerium into bioactive glasses using the sol–gel route is the focus of this work, with the goal to develop a material for tissue engineering with the potential to enhance osteogenesis.

Unfortunately most users tend to block their ads or ignore them. MyAds is a social adaptive hypermedia system for online advertising and its main goal is to explore how to make online ads more acceptable. In order to achieve such a goal, various technologies and techniques are used. This paper presents a theoretical framework as well as the system architecture for MyAds that was designed based on a set of hypotheses and an exploratory study. The system then was implemented and a pilot experiment was conducted to validate it. The main outcomes suggest that the system has provided personalized ads for users. The main implications suggest that the system can be used for further testing and validating. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptive%20hypermedia" title="adaptive hypermedia">adaptive hypermedia</a>, <a href="https://publications.waset.org/abstracts/search?q=e-advertisement" title=" e-advertisement"> e-advertisement</a>, <a href="https://publications.waset.org/abstracts/search?q=social" title=" social"> social</a>, <a href="https://publications.waset.org/abstracts/search?q=hypotheses" title=" hypotheses"> hypotheses</a>, <a href="https://publications.waset.org/abstracts/search?q=exploratory%20study" title=" exploratory study"> exploratory study</a>, <a href="https://publications.waset.org/abstracts/search?q=framework" title=" framework"> framework</a> </p> <a href="https://publications.waset.org/abstracts/5250/myads-a-social-adaptive-system-for-online-advertisment-from-hypotheses-to-implementation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5250.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">411</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">87</span> Nonconventional Method for Separation of Rosmarinic Acid: Synergic Extraction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lenuta%20Kloetzer">Lenuta Kloetzer</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandra%20C.%20Blaga"> Alexandra C.

Galaction</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rosmarinic acid, an ester of caffeic acid and 3-(3,4-dihydroxyphenyl) lactic acid, is considered a valuable compound for the pharmaceutical and cosmetic industries due to its antimicrobial, antioxidant, antiviral, anti-allergic, and anti-inflammatory effects. It can be obtained by extraction from vegetable or animal materials, by chemical synthesis and biosynthesis. Indifferent of the method used for rosmarinic acid production, the separation and purification process implies high amount of raw materials and laborious stages leading to high cost for and limitations of the separation technology. This study focused on separation of rosmarinic acid by synergic reactive extraction with a mixture of two extractants, one acidic (acid di-(2ethylhexyl) phosphoric acid, D2EHPA) and one with basic character (Amberlite LA-2). The studies were performed in experimental equipment consisting of an extraction column where the phases’ mixing was made by mean of a perforated disk with 45 mm diameter and 20% free section, maintained at the initial contact interface between the aqueous and organic phases. The vibrations had a frequency of 50 s⁻¹ and 5 mm amplitude. The extraction was carried out in two solvents with different dielectric constants (n-heptane and dichloromethane) in which the extractants mixture of varying concentration was dissolved. The pH-value of initial aqueous solution was varied between 1 and 7. The efficiency of the studied extraction systems was quantified by distribution and synergic coefficients. For calculating these parameters, the rosmarinic acid concentration in the initial aqueous solution and in the raffinate have been measured by HPLC. The influences of extractants concentrations and solvent polarity on the efficiency of rosmarinic acid separation by synergic extraction with a mixture of Amberlite LA-2 and D2EHPA have been analyzed. In the reactive extraction system with a constant concentration of Amberlite LA-2 in the organic phase, the increase of D2EHPA concentration leads to decrease of the synergic coefficient. This is because the increase of D2EHPA concentration prevents the formation of amine adducts and, consequently, affects the hydrophobicity of the interfacial complex with rosmarinic acid. For these reasons, the diminution of synergic coefficient is more important for dichloromethane. By maintaining a constant value of D2EHPA concentration and increasing the concentration of Amberlite LA-2, the synergic coefficient could become higher than 1, its highest values being reached for n-heptane. Depending on the solvent polarity and D2EHPA amount in the solvent phase, the synergic effect is observed for Amberlite LA-2 concentrations over 20 g/l dissolved in n-heptane. Thus, by increasing the concentration of D2EHPA from 5 to 40 g/l, the minimum concentration value of Amberlite LA-2 corresponding to synergism increases from 20 to 40 g/l for the solvent with lower polarity, namely, n-heptane, while there is no synergic effect recorded for dichloromethane. By analysing the influences of the main factors (organic phase polarity, extractant concentration in the mixture) on the efficiency of synergic extraction of rosmarinic acid, the most important synergic effect was found to correspond to the extractants mixture containing 5 g/l D2EHPA and 40 g/l Amberlite LA-2 dissolved in n-heptane. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amberlite%20LA-2" title="Amberlite LA-2">Amberlite LA-2</a>, <a href="https://publications.waset.org/abstracts/search?q=di%282-ethylhexyl%29%20phosphoric%20acid" title=" di(2-ethylhexyl) phosphoric acid"> di(2-ethylhexyl) phosphoric acid</a>, <a href="https://publications.waset.org/abstracts/search?q=rosmarinic%20acid" title=" rosmarinic acid"> rosmarinic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=synergic%20effect" title=" synergic effect"> synergic effect</a> </p> <a href="https://publications.waset.org/abstracts/82741/nonconventional-method-for-separation-of-rosmarinic-acid-synergic-extraction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82741.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">290</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">86</span> Generating 3D Anisotropic Centroidal Voronoi Tessellations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexandre%20Marin">Alexandre Marin</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandra%20Bac"> Alexandra Bac</a>, <a href="https://publications.waset.org/abstracts/search?q=Laurent%20Astart"> Laurent Astart</a> </p> <p class="card-text"><strong>Abstract:</strong></p> New numerical methods for PDE resolution (such as Finite Volumes (FV) or Virtual Elements Method (VEM)) open new needs in terms of meshing of domains of interest, and in particular, polyhedral meshes have many advantages. One way to build such meshes consists of constructing Restricted Voronoi Diagrams (RVDs) whose boundaries respect the domain of interest. By minimizing a function defined for RVDs, the shapes of cells can be controlled, e.g., elongated according to user-defined directions or adjusted to comply with given aspect ratios (anisotropy) and density variations. In this paper, our contribution is threefold: First, we introduce a new gradient formula for the Voronoi tessellation energy under a continuous anisotropy field. Second, we describe a meshing algorithm based on the optimisation of this function that we validate against state-of-the-art approaches. Finally, we propose a hierarchical approach to speed up our meshing algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anisotropic%20Voronoi%20diagrams" title="anisotropic Voronoi diagrams">anisotropic Voronoi diagrams</a>, <a href="https://publications.waset.org/abstracts/search?q=meshes%20for%20numerical%20simulations" title=" meshes for numerical simulations"> meshes for numerical simulations</a>, <a href="https://publications.waset.org/abstracts/search?q=optimisation" title=" optimisation"> optimisation</a>, <a href="https://publications.waset.org/abstracts/search?q=volumic%20polyhedral%20meshing" title=" volumic polyhedral meshing"> volumic polyhedral meshing</a> </p> <a href="https://publications.waset.org/abstracts/172242/generating-3d-anisotropic-centroidal-voronoi-tessellations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172242.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">115</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">85</span> A Conceptual E-Business Model and the Effect of Strategic Planning Parameters on E-Business Strategy Management and Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexandra%20Lipitakis">Alexandra Lipitakis</a>, <a href="https://publications.waset.org/abstracts/search?q=Evangelia%20A.%20E.%20C.%20Lipitakis"> Evangelia A.

Results: Child molesters' cognitive distortions including justifications, rationalizations and minimizations emerged from our data analysis (content analysis). Importantly, child molesters. adopted a particularly daring ‘role reversal’. Participants reported themselves as being ‘victims’. They said that the children (namely, their victims) were the ones who made the first move and got them in the mood for having sex with the children. Furthermore, we discuss our results in the context of the existing international academic literature on the area of this research.

Hence, the considered domain must be truncated to a smaller domain of interest. In addition, special boundary conditions, which absorb the outward travelling waves, need to be implemented in order to describe the system domains correctly. In this work, the linear one dimensional wave equation is approximated by utilizing the Fourier Galerkin approach. Furthermore, the artificial boundaries are realized with absorbing boundary conditions. Within this work, a systematic work flow for setting up the wave problem, including the absorbing boundary conditions, is proposed. As a result, a convenient modal system description with an effective absorbing boundary formulation is established.

Located on London’s doorstep, the 70,000-hectare region is under extraordinary pressure for regeneration, further development, and economic expansion, yet faces extreme challenges: sea-level rise and inadequate flood defenses, stormwater flooding and threatened infrastructure, loss of internationally important habitats, significant existing community deprivation, and lack of connectivity and access to green space. The brief was to embrace these challenges in the creation of a document that would form a key part of ASELA’s Joint Strategic Framework and feed into local plans and master plans. Thus, helping to tackle climate change, ecological collapse, and social inequity at a regional scale whilst creating a relationship and awareness between urban communities and the surrounding landscapes and nature. The SEGBI project applied a ‘land-based’ methodology, combined with a co-design approach involving numerous stakeholders, to explore how living infrastructure can address these significant issues, reshape future planning and development, and create thriving places for the whole community of life. It comprised three key stages, including Baseline Review; Green and Blue Infrastructure Assessment; and the final Green and Blue Infrastructure Report. The resulting proposals frame an ambitious vision for the delivery of a new regional South Essex Estuary (SEE) Park – 24,000 hectares of protected and connected landscapes. This unified parkland system will drive effective place-shaping and “leveling up” for the most deprived communities while providing large-scale nature recovery and biodiversity net gain. Comprehensive analysis and policy recommendations ensure best practices will be embedded within planning documents and decisions guiding future development. Furthermore, a Natural Capital Account was undertaken as part of the strategy showing the tremendous economic value of the natural assets. This strategy sets a pioneering precedent that demonstrates how the prioritisation of living infrastructure has the capacity to address climate change and ecological collapse, while also supporting sustainable housing, healthier communities, and resilient infrastructures. It was only achievable through a collaborative and cross-boundary approach to strategic planning and growth, with a shared vision of place, and a strong commitment to delivery. With joined-up thinking and a joined-up region, a more impactful plan for South Essex was developed that will lead to numerous environmental, social, and economic benefits across the region, and enhancing the landscape and natural environs on the periphery of one of the largest cities in the world. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20and%20blue%20infrastructure" title=" green and blue infrastructure"> green and blue infrastructure</a>, <a href="https://publications.waset.org/abstracts/search?q=landscape%20architecture" title=" landscape architecture"> landscape architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=master%20planning" title=" master planning"> master planning</a>, <a href="https://publications.waset.org/abstracts/search?q=regional%20planning" title=" regional planning"> regional planning</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20equity" title=" social equity"> social equity</a> </p> <a href="https://publications.waset.org/abstracts/162746/a-case-for-strategic-landscape-infrastructure-south-essex-estuary-park" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162746.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">97</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">80</span> 3D Virtualization through Data Collected from Measurements of Mobile Signal Reception Power Levels (LTE) Band at Escuela Superior Politécnica de Chimborazo in Riobamba-Ecuador</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Cuenca">Sandra Cuenca</a>, <a href="https://publications.waset.org/abstracts/search?q=Steven%20Chango"> Steven Chango</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabian%20Chamba"> Fabian Chamba</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandra%20Vaca"> Alexandra Vaca</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This project addresses a representation of a virtual environment based on the analysis of the RSRP (Reference Signal Received Power) obtained by the Network Cell Info Lite application at the Escuela Superior Politécnica de Chimborazo (ESPOCH) considering the open areas of the Business Administration Department in the 4G LTE Frequency (band 2) of Claro Telephony at a frequency of 1967. 5 MHz, where measurements were performed from 17:00 UTC-05:00. The indicators required for the simulation of the environment designed in sketchup were focused especially on the power levels obtained where it was possible to represent the scenario with real power values obtained in each concentric radius of a total of 3 campaigns of 200 samples each, where the values vary between 84.6 dBm to 115.5 dBm having average power values for each of the 23 radiuses which are introduced in a virtual environment, allowing users to immerse themselves in it, where they can explore 3D virtual environments, generating a color scale from 0 to 10 with red being the weakest signal and green the signal with the best intensity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=virtualization" title="virtualization">virtualization</a>, <a href="https://publications.waset.org/abstracts/search?q=LTE" title=" LTE"> LTE</a>, <a href="https://publications.waset.org/abstracts/search?q=radios" title=" radios"> radios</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20intensity%20levels%20colors" title=" power intensity levels colors"> power intensity levels colors</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20signal%20reception%20power" title=" mobile signal reception power"> mobile signal reception power</a> </p> <a href="https://publications.waset.org/abstracts/170817/3d-virtualization-through-data-collected-from-measurements-of-mobile-signal-reception-power-levels-lte-band-at-escuela-superior-politecnica-de-chimborazo-in-riobamba-ecuador" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170817.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">89</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">79</span> Polarization of Glass with Positive and Negative Charge Carriers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Valentina%20V.%20Zhurikhina">Valentina V.

The usage of the poling for second optical harmonic generation, fabrication of optical waveguides and electrooptic modulators was also reported. Nevertheless, the detailed description of the poling of glasses, containing multiple charge carriers is still under discussion. In particular, the role of possible migration of electrons in the space charge formation usually remains out of the question. In this work, we performed the numerical simulation of thermal poling of a silicate glass, containing Na, K, Mg, and Ca. We took into consideration the contribution of electrons in the polarization process. The possible explanation of migration of electrons can be the break of non-bridging oxygen bonds. It was found, that the modeled depth of the space charge region is about 10 times higher if the migration of the negative charges is taken under consideration. The simulated profiles of cations, participating in the polarization process, are in a good agreement with the experimental data, obtained by glow discharge spectroscopy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glass%20poling" title="glass poling">glass poling</a>, <a href="https://publications.waset.org/abstracts/search?q=charge%20transport" title=" charge transport"> charge transport</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=concentration%20profiles" title=" concentration profiles"> concentration profiles</a> </p> <a href="https://publications.waset.org/abstracts/67507/polarization-of-glass-with-positive-and-negative-charge-carriers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67507.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">78</span> Geochemical and Mineralogical Characteristics of Soils in Areas Affected by the Fires of August 2021 at the Ilia Prefecture Greece</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dionisios%20Panagiotaras">Dionisios Panagiotaras</a>, <a href="https://publications.waset.org/abstracts/search?q=Pavlos%20Avramidis"> Pavlos Avramidis</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimitrios%20Papoulis"> Dimitrios Papoulis</a>, <a href="https://publications.waset.org/abstracts/search?q=Dionysios%20Koulougliotis"> Dionysios Koulougliotis</a>, <a href="https://publications.waset.org/abstracts/search?q=Dionisis%20C.%20Christodoulopoulos"> Dionisis C.

The mineralogical composition of the samples consists of quartz, calcite, albite, oligoclase, anorthite (feldspars), smectite, kaolinite and illite (clays). Quartz ranges from 38.21% to 57.49% with an average of 48.43%, calcite ranges from 2.55% to 25.09% with an average of 13.92%, feldspars ranges from 7.76% to 25.87% with an average of 17.02% and clays ranges from 4.39% to 43.43% with an average of 20.63%. Geochemical analyses of the soil samples applied for total organic carbon (TOC), total nitrogen (TN), total phosphorous (TP), Cu, Zn, Mn and Fe. Statistical analysis of the data shows a positive correlation between clays and Zn, Mn, Fe. TOC and TN show a strong positive correlation, while Fe shows a strong negative correlation with calcite. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soils" title="soils">soils</a>, <a href="https://publications.waset.org/abstracts/search?q=geochemistry" title=" geochemistry"> geochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=mineralogy" title=" mineralogy"> mineralogy</a>, <a href="https://publications.waset.org/abstracts/search?q=woodland" title=" woodland"> woodland</a>, <a href="https://publications.waset.org/abstracts/search?q=forest" title=" forest"> forest</a> </p> <a href="https://publications.waset.org/abstracts/173706/geochemical-and-mineralogical-characteristics-of-soils-in-areas-affected-by-the-fires-of-august-2021-at-the-ilia-prefecture-greece" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173706.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">95</span> </span> </div> </div> <ul class="pagination"> <li class="page-item disabled"><span class="page-link">&lsaquo;</span></li> <li class="page-item active"><span class="page-link">1</span></li> <li class="page-item"><a class="page-link" href="https://publications.waset.org/abstracts/search?q=Alexandra%20Sweny&amp;page=2">2</a></li> <li class="page-item"><a class="page-link" href="https://publications.waset.org/abstracts/search?q=Alexandra%20Sweny&amp;page=3">3</a></li> <li class="page-item"><a class="page-link" href="https://publications.waset.org/abstracts/search?q=Alexandra%20Sweny&amp;page=4">4</a></li> <li class="page-item"><a class="page-link" href="https://publications.waset.org/abstracts/search?q=Alexandra%20Sweny&amp;page=2" rel="next">&rsaquo;</a></li> </ul> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">&copy;
