For the study were taken six samples of Serra da Estrela cheese produced with 6 different ecotypes of thistle in a dairy situated in Penalva do Castelo. The chemical properties evaluated were moisture content, protein, fat, ash, chloride and pH; the physical properties studied were color and texture; and finally a sensory evaluation was undertaken. The results showed moisture varying in the range 40-48%, protein in the range 15-20%, fat between 41-45%, ash between 3.9-5.0% and chlorides varying from 1.2 to 3.0%. The pH varied from 4.8 to 5.4. The textural properties revealed that the crust hardness is relatively low (maximum 7.3 N), although greater than flesh firmness (maximum 1.7 N), and also that these cheeses are in fact soft paste type, with measurable stickiness and intense adhesiveness. The color analysis showed that the crust is relatively light (L* over 50), and with a predominant yellow coloration (b* around 20 or over) although with a slight greenish tone (a* negative). The results of the sensory analysis did not show great variability for most of the attributes measured, although some differences were found in attributes such as crust thickness, crust uniformity, and creamy flesh. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20composition" title="chemical composition">chemical composition</a>, <a href="https://publications.waset.org/abstracts/search?q=color" title=" color"> color</a>, <a href="https://publications.waset.org/abstracts/search?q=sensorial%20analysis" title=" sensorial analysis"> sensorial analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Serra%20da%20Estrela%20cheese" title=" Serra da Estrela cheese"> Serra da Estrela cheese</a>, <a href="https://publications.waset.org/abstracts/search?q=texture" title=" texture"> texture</a> </p> <a href="https://publications.waset.org/abstracts/22235/effect-of-thistle-ecotype-in-the-physical-chemical-and-sensorial-properties-of-serra-da-estrela-cheese" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22235.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">300</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">131</span> Hermitical Landscapes: The Congregation of Saint Paul of Serra De Ossa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rolando%20Volzone">Rolando Volzone</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Congregation of Saint Paul of Serra de Ossa (Ossa Mountain) was founded in 1482, originated by the eremitic movement of the homens da pobre vida (poor life men), which is documented since 1366. The community of hermits expanded up to the first half of the 15th century, mostly in southern Portugal in the Alentejo region. In 1578, following a process of institutionalization led by the Church, an autonomous congregation was set up, affiliated in the Hungarian Order of Saint Paul the First Hermit, until 1834, when the decree of dissolution of the religious orders disbanded all the convents and monasteries in Portugal. The architectural evidences that reached our days as a legacy of the hermitical movement in Serra de Ossa, although studied and analysed from an historical point of view, are still little known with respect to the architectural characteristics of its physical implantation and its relationship with the natural systems. This research intends to expose the appropriation process of the locus eremus as a starting point for the interpretation of this landscape, evidencing the close relationship between the religious experience and the physical space chosen to reach the perfection of the soul. The locus eremus is thus determined not only by practical aspects such as the absolute and relative location, orography, existence of water resources, or the King’s favoring to the religious and settlement action of the hermits, but also by spiritual aspects related to the symbolism of the physical elements present and the solitary walk of these men. These aspects, combined with the built architectural elements and other exerted human action, may be fertile ground for the definition of a hypothetical hermitical landscape based on the sufficiently distinctive characteristics that sustain it. The landscape built by these hermits is established as a cultural and material heritage, and its preservation is of utmost importance. They deeply understood this place and took advantage of its natural resources, manipulating them in an ecological and economically sustainable way, respecting the place, without overcoming its own genius loci but becoming part of it. <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=congregation%20of%20Saint%20Paul%20of%20Serra%20de%20Ossa" title=" congregation of Saint Paul of Serra de Ossa"> congregation of Saint Paul of Serra de Ossa</a>, <a href="https://publications.waset.org/abstracts/search?q=heremitical%20landscape" title=" heremitical landscape"> heremitical landscape</a>, <a href="https://publications.waset.org/abstracts/search?q=locus%20eremus" title=" locus eremus"> locus eremus</a> </p> <a href="https://publications.waset.org/abstracts/87294/hermitical-landscapes-the-congregation-of-saint-paul-of-serra-de-ossa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87294.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">233</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">130</span> Identity Conflict between Social and Business Entrepreneurs: The Challenge of Constructing a Novel Social Identity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rui%20G.%20Ser%C3%B4dio">Rui G.

Specifically, we address how both differentiation and assimilation processes are set of in the context of constructing a novel, distinctive and socially salient – social entrepreneurs. As part of a larger research line, a quasi-experimental study with Social and Business Entrepreneurs, as well as “Lay People” provided evidence consistent with our predictions: (1) Social Entrepreneurs, in contrast with Lay People and Business Entrepreneurs, value more strongly social identity than personal identity, and the later is the only group that values Personal Differentiation; (2) unlike Entrepreneurs, Social Entrepreneurs display an ingroup bias across group evaluations; (3) Lay People, display a self-serving bias, although, overall, they allocate a more positive image to the target groups; (4) combining own vs. others evaluations across all groups, Social Entrepreneurs receive the more positive value. From the standpoint of social identity and self-categorization theories and their approach to group process, we discuss the processes of intergroup comparison and differentiation as core processes in the construction of a positive social identity. We illustrate it within the context of social entrepreneurship, a political and social “wave” that flows across Europe at this time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=group%20processes" title="group processes">group processes</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20entrepreneurship" title=" social entrepreneurship"> social entrepreneurship</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20identity" title=" social identity"> social identity</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20entrepreneurs" title=" business entrepreneurs"> business entrepreneurs</a> </p> <a href="https://publications.waset.org/abstracts/23085/identity-conflict-between-social-and-business-entrepreneurs-the-challenge-of-constructing-a-novel-social-identity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23085.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">695</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">129</span> Intimate Partner Offenders and Prevalent Affective-Cognitive Functioning: A Study with Inmates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexandra%20Serra">Alexandra Serra</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Torr%C3%A3o"> Nadia Torrão</a>, <a href="https://publications.waset.org/abstracts/search?q=Rui%20G.%20Ser%C3%B4dio"> Rui G.

Project ISA, supported by EU regional funding, was design as part of a broader model developed by SIMLab–Social Inclusion Monitoring Laboratory, in which the relation University-Community is a core element. The project illustrates how University of Porto developed a large scale project of applied psychology research in a close partnership with 18 municipalities that cover almost all regions of Portugal, and with a private architecture enterprise, specialized in inclusive accessibility and “design for all”. Three fundamental goals were defined: (1) creation of a model that would promote the effective civic participation of local citizens; (2) the “voice” of such participation should be both individual and collective; (3) the scientific and technical framework should serve as one of the bases for political decision on inclusive accessibility local planning. The two main studies were run in a standardized model across all municipalities and the samples of the three modalities of community participation were the following: individual participation based on 543 semi-structured interviews and 6373 inquiries; collective participation based on group session with 302 local citizens. We present some of the broader findings of Project SIA and discuss how they relate to our applied research model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=applied%20psychology" title="applied psychology">applied psychology</a>, <a href="https://publications.waset.org/abstracts/search?q=collective%20identity" title=" collective identity"> collective identity</a>, <a href="https://publications.waset.org/abstracts/search?q=community%20participation" title=" community participation"> community participation</a>, <a href="https://publications.waset.org/abstracts/search?q=inclusive%20accessibility" title=" inclusive accessibility"> inclusive accessibility</a> </p> <a href="https://publications.waset.org/abstracts/27740/a-model-of-applied-psychology-research-defining-community-participation-and-collective-identity-as-a-major-asset-for-strategic-planning-and-political-decision-the-project-sia-social-inclusion-through-accessibility" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27740.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">446</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">126</span> Reinforced Concrete Design Construction Issues and Earthquake Failure-Damage Responses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Husnu%20Korkmaz">Hasan Husnu Korkmaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Serra%20Zerrin%20Korkmaz"> Serra Zerrin Korkmaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Earthquakes are the natural disasters that threat several countries. Turkey is situated on a very active earthquake zone. During the recent earthquakes, thousands of people died due to failure of reinforced concrete structures. Although Turkey has a very sufficient earthquake code, the design and construction mistakes were repeated for old structures. Lack of the control mechanism during the construction process may be the most important reason of failure. The quality of the concrete and poor detailing of steel or reinforcement is the most important headings. In this paper, the reasons of failure of reinforced concrete structures were summarized with relevant photos.

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">122</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">121</span> Baring Witness, Bearing Withness: Paradoxes of Testimony in J.M.

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">120</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">119</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.

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">113</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.

These computer vision-based positioning approaches are low-cost to implement, mainly when it uses a mobile camera. The present study aims to create a design of a fiducial marker for a low-cost indoor localization system. The marker is tape-shaped to perform a continuous reading employing two detection algorithms, one for greater distances and another for smaller distances. Therefore, the location service is always operational, even with variations in capture distance. A minimal localization and reading algorithm were implemented for the proposed marker design, aiming to validate it. The accuracy tests consider readings varying the capture distance between [0.5, 10] meters, comparing the proposed marker with others. The tests showed that the proposed marker has a broader capture range than the ArUco and QRCode, maintaining the same size. Therefore, reducing the visual pollution and maximizing the tracking since the ambient can be covered entirely. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multiscale%20recognition" title="multiscale recognition">multiscale recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=indoor%20localization" title=" indoor localization"> indoor localization</a>, <a href="https://publications.waset.org/abstracts/search?q=tape-shaped%20marker" title=" tape-shaped marker"> tape-shaped marker</a>, <a href="https://publications.waset.org/abstracts/search?q=fiducial%20marker" title=" fiducial marker"> fiducial marker</a> </p> <a href="https://publications.waset.org/abstracts/163542/tape-shaped-multiscale-fiducial-marker-a-design-prototype-for-indoor-localization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163542.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">134</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">109</span> Assessing Lithium Recovery from Secondary Sources</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carolina%20A.%20Santos">Carolina A.

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">108</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. Not only the amount but also the distribution of different phases determines a polymers’ degradability. 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">107</span> First Surveillance Results Bring No Evidence of SARS-CoV-2 Spillback in Bats of Central-Southern Italy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hiba%20Dakroub">Hiba Dakroub</a>, <a href="https://publications.waset.org/abstracts/search?q=Danilo%20Russo"> Danilo Russo</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Cistrone"> Luca Cistrone</a>, <a href="https://publications.waset.org/abstracts/search?q=Francesco%20Serra"> Francesco Serra</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanna%20Fusco"> Giovanna Fusco</a>, <a href="https://publications.waset.org/abstracts/search?q=Esterina%20De%20Carlo"> Esterina De Carlo</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Grazia%20Amoroso"> Maria Grazia Amoroso</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The question of the origin of SARS-CoV-2 and the cycle of transmission between humans and animals is still unanswered. One serious concern associated with the SARS-CoV-2 pandemic is that the virus might spill back from humans to wildlife, which would render some animal species reservoirs of the human virus. The aim of the present study is to monitor the potential risk of SARS-CoV-2 reverse infection from humans to bats, by performing bat surveillance from different sites in Central-Southern Italy. We collected 240 droppings or saliva from 129 bats and tested them using specific and general primers of SARS-COV-2 and coronaviruses respectively. All samples, including 127 nasal swabs and 113 fecal droppings resulted negative for SARS-COV-2, and these results were confirmed by testing the samples with the Droplet Digital PCR. Also, an end-point RT-PCR was performed and no sample showed specific bands. The absence of SARS-CoV-2 in the bats we surveyed is a first step towards a better understanding of reverse transmission to bats of this virus. We hope our first contribution will encourage the establishment of systematic surveillance of wildlife, and specifically bats, to help prevent reverse zoonotic episodes that would jeopardize human health as well as biodiversity conservation and management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coronaviruses" title="coronaviruses">coronaviruses</a>, <a href="https://publications.waset.org/abstracts/search?q=bats" title=" bats"> bats</a>, <a href="https://publications.waset.org/abstracts/search?q=zoonotic%20viruses" title=" zoonotic viruses"> zoonotic viruses</a>, <a href="https://publications.waset.org/abstracts/search?q=spillback" title=" spillback"> spillback</a>, <a href="https://publications.waset.org/abstracts/search?q=SARS-CoV-2" title=" SARS-CoV-2"> SARS-CoV-2</a> </p> <a href="https://publications.waset.org/abstracts/150760/first-surveillance-results-bring-no-evidence-of-sars-cov-2-spillback-in-bats-of-central-southern-italy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150760.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">119</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> 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.

The homogeneity of success achievement motivation was not a factor in the effectiveness of the football team. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compatibility" title="compatibility">compatibility</a>, <a href="https://publications.waset.org/abstracts/search?q=failure%20avoidance%20motivation" title=" failure avoidance motivation"> failure avoidance motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=football" title=" football"> football</a>, <a href="https://publications.waset.org/abstracts/search?q=heterogeneity" title=" heterogeneity"> heterogeneity</a>, <a href="https://publications.waset.org/abstracts/search?q=homogeneity" title=" homogeneity"> homogeneity</a>, <a href="https://publications.waset.org/abstracts/search?q=soccer" title=" soccer"> soccer</a>, <a href="https://publications.waset.org/abstracts/search?q=sport%20team" title=" sport team"> sport team</a>, <a href="https://publications.waset.org/abstracts/search?q=success%20achievement%20motivation" title=" success achievement motivation"> success achievement motivation</a> </p> <a href="https://publications.waset.org/abstracts/59006/psychological-compatibility-of-football-players-according-to-success-achievement-and-failure-avoidance-motivation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59006.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">365</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> Cerium Salt Effect in 70s Bioactive Glass</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alessandra%20N.%20Santos">Alessandra N.

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. A bioactive glass composition based on 70% SiO2–30% CaO is produced with the addition of cerium. The analyses XRD, FTIR, SEM/EDS, BET/BJH, in vitro bioactivity test and the Cell viability assay were performed. The results show that cerium remains in the bioactive glass structure.

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">103</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
