The present study used a large data set of structural gene sequences, including newly generated ones and sequences available in the GenBank database to further analyze the diversity and to identify selective pressures and recombination spots. There were some deletions or insertions in the analyzed regions in isolates of the Italy-02 and D274 genotypes. Whereas, there were no insertions or deletions observed in the isolates of the Massachusetts and 4/91 genotype. The hypervariable nucleotide sequence regions spanned positions 152–239, 554–582, 686–737 and 802–912 in the S1 sub-unit of the all analyzed genotypes. The nucleotide sequence data of the E gene showed that this gene was comparatively unstable and subjected to a high frequency of mutations. The M gene showed substitutions consistently distributed except for a region between nucleotide positions 250–680 that remained conserved. The lowest variation in the nucleotide sequences of ORF5a was observed in the isolates of the D274 genotype. While, ORF5b and N gene sequences showed highly conserved regions and were less subjected to variation. Genes ORF3a, ORF3b, M, ORF5a, ORF5b and N presented negative selective pressure among the analyzed isolates. However, some regions of the ORFs showed favorable selective pressure(s). The S1 and E proteins were subjected to a high rate of mutational substitutions and non-synonymous amino acids. Strong signals of recombination breakpoints and ending break point were observed in the S and N genes. Overall, the results of this study revealed that very likely the strong selective pressures in E, M and the high frequency of substitutions in the S gene can probably be considered the main determinants in the evolution of IBV. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=IBV" title="IBV">IBV</a>, <a href="https://publications.waset.org/abstracts/search?q=avian%20infectious%20bronchitis" title=" avian infectious bronchitis"> avian infectious bronchitis</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20genes" title=" structural genes"> structural genes</a>, <a href="https://publications.waset.org/abstracts/search?q=genotypes" title=" genotypes"> genotypes</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20diversity" title=" genetic diversity"> genetic diversity</a> </p> <a href="https://publications.waset.org/abstracts/24427/heterogeneity-of-genes-encoding-the-structural-proteins-of-avian-infectious-bronchitis-virus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24427.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">434</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">25</span> Female Subjectivity in William Faulkner's Light in August </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azza%20Zagouani">Azza Zagouani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: In the work of William Faulkner, characters often evade the boundaries and categories of patriarchal standards of order. Female characters like Lena Grove and Joanna Burden cross thresholds in attempts to gain liberation, while others fail to do so. They stand as non-conformists and refuse established patterns of feminine behavior, such as marriage and motherhood after. They refute submissiveness, domesticity and abstinence to reshape their own identities. The presence of independent and creative women represents new, unconventional images of female subjectivity. This paper will examine the structures of submission and oppression faced by Lena and Joanna, and will show how, in the end, they reshape themselves and their identities, and disrupt or even destroy patriarchal structures. Objectives: Participants will understand through the examples of Lena Grove and Joanna Burden that female subjectivities are constructions, and are constantly subject to change. Approaches: Two approaches will be used in the analysis of the subjectivity formation of Lena Grove and Joanna Burden. Following the arguments propounded by Judith Butler, We explore the ways in which Lena Grove maneuvers around the restrictions and the limitations imposed on her without any physical or psychological violence. She does this by properly performing the roles prescribed to her gendered body. Her repetitious performances of these roles are both the ones that are constructed to confine women and the vehicle for her travel. Her performance parodies the prescriptive roles and thereby reveals that they are cultural constructions. Second, We will explore the argument propounded by Kristeva that subjectivity is always in a state of development because we are always changing in context with changing circumstances. For example, in Light in August, Lena Grove changes the way she defines herself in light of the events of the novel. Also, Kristeva talks about stages of development: the semiotic stage and the symbolic stage. In Light in August, Joanna shows different levels of subjectivity as time passes. Early in the novel, Joanna is very connected to her upbringing. This suggests Kristeva’s concept of the semiotic, in which the daughter identifies closely to her parents. Kristeva relates the semiotic to a strong daughter/mother connection, but in the novel it is strong daughter/father/grandfather identification instead. Then as Joanna becomes sexually involved with Joe, she breaks off, and seems to go into an identity crisis. To me, this represents Kristeva’s move from the semiotic to the symbolic. When Joanna returns to a religious fanaticism, she is returning to a semiotic state. Detailed outline: At the outset of this paper, We will investigate the subjugation of women: social constraints, and the formation of the feminine identity in Light in August. Then, through the examples of Lena Grove’s attempt to cross the boundaries of community moralities and Joanna Burden’s refusal to submit to the standards of submissiveness, domesticity, and obstinance, We will reveal the tension between progressive conceptions of individual freedom and social constraints that limit this freedom. In the second part of the paper, We will underscore the rhetoric of femininity in Light in August: subjugation through naming. The implications of both female’s names offer a powerful contrast between the two different forms of subjectivity. Conclusion: Through Faulkner’s novel, We demonstrate that female subjectivity is an open-ended issue. The spiral shaping of its form maintains its characteristics as a process changing according to different circumstances. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=female%20subjectivity" title="female subjectivity">female subjectivity</a>, <a href="https://publications.waset.org/abstracts/search?q=Faulkner%E2%80%99s%20light%20August" title=" Faulkner’s light August"> Faulkner’s light August</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a>, <a href="https://publications.waset.org/abstracts/search?q=sexuality" title=" sexuality"> sexuality</a>, <a href="https://publications.waset.org/abstracts/search?q=diversity" title=" diversity "> diversity </a> </p> <a href="https://publications.waset.org/abstracts/32084/female-subjectivity-in-william-faulkners-light-in-august" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32084.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">396</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">24</span> Evolution of Rock-Cut Caves of Dhamnar at Dhamnar, MP</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abhishek%20Ranka">Abhishek Ranka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rock-cut Architecture is a manifestation of human endurance in constructing magnificent structures by sculpting and cutting entire hills. Cave Architecture in India form an important part of rock-cut development and is among the most prolific examples of rock-cut architecture in the world. There are more than 1500 rock-cut caves in various regions of India. Among them mostly are located in western India, more particularly in the state of Maharashtra. Some of the rock-cut caves are located in the central region of India, which is presently known as Malawa (Madhya Pradesh). The region is dominated by the vidhyachal hill ranges toward the west, dotted with the coarse laterite rock. Dhamnar Caves have been excavated in the central region of Mandsaur Dist. With a combination of shared sacred faiths. The earliest rock-cut activity began in the north, in Bihar, where caves were excavated in the Barabar and the Nagarjuni hills during the Mauryan period (3rd century BCE). The rock-cut activity then shifts to the central part of India in Madhya Pradesh, where the caves at Dhamnar, Bagh, Udayagiri, Poldungar, etc. excavated between 3rdto 9ᵗʰ CE. The rock-cut excavation continued to flourish in Madhya Pradesh till 10ᵗʰ century CE, simultaneously with monolithic Hindu temples. Dhamnar caves fall into four architectural typologies: the Lena caves, Chaitya caves, Viharas & Lena-Chaityagriha caves. The Buddhist rock-cutting activity in central India is divisible into two phases. In the first phase (2ndBCE-3rd CE), the Buddha image is conspicuously absent. After a lapse of about three centuries, activity begins again, and the Buddha images this time are carved. The former group belongs to the Hinayana (Lesser Vehicle) phase and the latter to the Mahayana (Greater Vehicle). Dhamnar caves has an elaborate facades, pillar capitals, and many more creative sculptures in various postures. These caves were excavated against the background of invigorating trade activities and varied socio-religious or Socio Cultural contexts. These caves also highlights the wealthy and varied patronage provided by the dynasties of the past. This paper speaks about the appraisal of the rock cut mechanisms, design strategies, and approaches while promoting a scope for further research in conservation practices. Rock-cut sites, with their physical setting and various functional spaces as a sustainable habitat for centuries, has a heritage footprint with a researchquotient. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rock-cut%20architecture" title="rock-cut architecture">rock-cut architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=buddhism" title=" buddhism"> buddhism</a>, <a href="https://publications.waset.org/abstracts/search?q=hinduism" title=" hinduism"> hinduism</a>, <a href="https://publications.waset.org/abstracts/search?q=Iconography" title=" Iconography"> Iconography</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20architectural%20typologies" title=" and architectural typologies"> and architectural typologies</a>, <a href="https://publications.waset.org/abstracts/search?q=Jainism" title=" Jainism"> Jainism</a> </p> <a href="https://publications.waset.org/abstracts/152474/evolution-of-rock-cut-caves-of-dhamnar-at-dhamnar-mp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152474.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">153</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">23</span> Level up Entrepreneurial Behaviors: A Case Study on the Use of Gamification to Encourage Entrepreneurial Acting and Thinking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lena%20Murawski">Lena Murawski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Currently, researchers and experts from the business world recognize entrepreneurial behaviors as a decisive factor for economic success, allowing firms to adapt to changing internal and external needs. The purpose of this study is to explore how gamification can enhance entrepreneurial behaviors, reporting on a gamification project in a new venture operating in the IT sector in Germany. This article is based on data gathered from observations of pre‐ and post‐implementation in the case company. Results have indicated that the use of gamification encourages entrepreneurial behaviors, especially relating to seeking ways on how to integrate new employees, improve teamwork and communication, and to adapt existing processes to increase productivity. The interdisciplinary dialogue furthers our understanding of factors that foster entrepreneurial behaviors.

In this paper, we present a Model Predictive Control (MPC) design of a centralized, server-based ACC-System, whereby the vehicular platoon is modeled and controlled as a whole. It is then proven that the proposed MPC design guarantees asymptotic stability and hence string stability of the platoon. The Networked MPC design is chosen to be able to integrate system constraints optimally as well as to reduce the effects of communication delay and packet loss. The performance of the proposed controller is then simulated and analyzed in an LTE communication scenario using the LTE/EPC Network Simulator LENA, which is based on the ns-3 network simulator. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptive%20cruise%20control" title="adaptive cruise control">adaptive cruise control</a>, <a href="https://publications.waset.org/abstracts/search?q=centralized%20server" title=" centralized server"> centralized server</a>, <a href="https://publications.waset.org/abstracts/search?q=networked%0D%0Amodel%20predictive%20control" title=" networked model predictive control"> networked model predictive control</a>, <a href="https://publications.waset.org/abstracts/search?q=string%20stability" title=" string stability"> string stability</a> </p> <a href="https://publications.waset.org/abstracts/6450/modeling-and-control-design-of-a-centralized-adaptive-cruise-control-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6450.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">514</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">21</span> Investigating the Mechanical Properties of Geopolymer Concrete Containing Microencapsulated Phase Change Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shima%20Pilehvar">Shima Pilehvar</a>, <a href="https://publications.waset.org/abstracts/search?q=Vinh%20Duy%20Cao"> Vinh Duy Cao</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20M.%20Szczotok"> Anna M.

However, addition of MPCM to Portland cement concrete is known to reduce the compressive strength of the concrete. Accordingly, it is interesting to also examine the effect of adding MPCM to geopolymer concrete. Geopolymer binder is synthesized by mixing aluminosilicate materials in amorphous form with a strong alkali activator, and have a much lower CO2 footprint than Portland cement concrete. In this study, the mechanical properties of fly ash-based geopolymer concrete with different types and contents of MPCM were investigated at different curing temperatures. The aim was to find the optimum amount of MPCM which still maintain the workability and compressive strength at an acceptable level. The results revealed that both workability and compressive strength of geopolymer concrete decrease after adding MPCM.

Embedding improves privacy and may reduce prediction delay. In addition, the number of transmissions is reduced. However, quality factors such as prediction accuracy, fault detection efficiency and coordinated control of the overall system suffer. Here, we discuss and highlight the trade-offs that should be considered when choosing between embedding and centralized ML, especially for multihop networks. In addition, we present estimations that demonstrate the energy trade-offs between embedded and centralized ML. Although the total network energy consumption is lower with central prediction, it makes the network more prone for partitioning due to the high forwarding load on the one-hop nodes. Moreover, the continuous improvements in the number of operations per joule for embedded devices will move the energy balance toward embedded prediction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=central%20machine%20learning" title="central machine learning">central machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=embedded%20machine%20learning" title=" embedded machine learning"> embedded machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20consumption" title=" energy consumption"> energy consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20machine%20learning" title=" local machine learning"> local machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensor%20networks" title=" wireless sensor networks"> wireless sensor networks</a>, <a href="https://publications.waset.org/abstracts/search?q=WSN" title=" WSN"> WSN</a> </p> <a href="https://publications.waset.org/abstracts/127522/discussing-embedded-versus-central-machine-learning-in-wireless-sensor-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127522.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">153</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">19</span> Robust Data Image Watermarking for Data Security</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harsh%20Vikram%20Singh">Harsh Vikram Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ankur%20Rai"> Ankur Rai</a>, <a href="https://publications.waset.org/abstracts/search?q=Anand%20Mohan"> Anand Mohan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we propose secure and robust data hiding algorithm based on DCT by Arnold transform and chaotic sequence.

Nowadays, most components are being developed via a substitution approach, which aims at replacing conventional components with natural alternatives who are then being processed, shaped and manufactured to fit the desired application. This contribution introduces a novel approach to the development of bio-based products that decreases resource consumption and increases recyclability. In this approach, natural organisms like plants or trees are not being used in a processed form, but grow into a near net shape before then being harvested and utilized as building components. By minimizing the conventional production steps, the amount of resources used in manufacturing decreases whereas the recyclability increases. This paper presents the approach of technical product harvesting, explains the theoretical basis as well as the matching process of product requirements and biological properties, and shows first results of the growth manipulation studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design%20with%20nature" title="design with nature">design with nature</a>, <a href="https://publications.waset.org/abstracts/search?q=eco%20manufacturing" title=" eco manufacturing"> eco manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20construction%20materials" title=" sustainable construction materials"> sustainable construction materials</a>, <a href="https://publications.waset.org/abstracts/search?q=technical%20product%20harvesting" title=" technical product harvesting "> technical product harvesting </a> </p> <a href="https://publications.waset.org/abstracts/26137/growing-architecture-technical-product-harvesting-of-near-net-shape-building-components" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26137.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">499</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">17</span> Repellent Activity of Nanoemulsion Essential Oil of Eucalyptus Globulus Labill on Ephestia kuehniella (Lepidoptera: Pyralidae)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lena%20Emamjomeh">Lena Emamjomeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sohrab%20Imani"> Sohrab Imani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, the use of encapsulation technology of pesticides causes an increase in the efficiency and controlled release of these substances. Controlled release by nanoencapsulated formulations allows the essential oil to be used more effectively over a given time interval, suitability to the mode of application and minimization of environmental damage. The essential oil from Eucalyptus globulus exhibited an average yield of 1.19% and presented 1,8-cineol (59.08%) as the major component. Nanoemulsion essential oil was carried out by the method of gum - maltodextrin using homogenization and morphology and size were determined by TEM. Several concentrations were prepared, and then third instar larvae of E.kuehniella were introduced into each treatment. Then, repellent activity was determined after 1, 3 and 24 h from commencement. This study reveals that at a concentration of 1.5 ppm, the nanoemulsion of E. globulus essential oil on the flour disc was shown here to possess more repellent activity (85%) than E.kuehniella compared to natural essential oil (5%) before formulation after 24h. The repellent activity varied with application method concentrations and exposure time. The results showed higher repellent rates in nanoemulsion than in essential oil due to controlled-release formulations allowing smaller quantities of essential oil to be used more effectively over a given time interval. Findings led to the conclusion that encapsulated technology of essential oils can enhance their control release and persistence under controlled conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanoemulsion" title="nanoemulsion">nanoemulsion</a>, <a href="https://publications.waset.org/abstracts/search?q=eucalyptus%20globulus" title=" eucalyptus globulus"> eucalyptus globulus</a>, <a href="https://publications.waset.org/abstracts/search?q=ephestia%20kuehniella" title=" ephestia kuehniella"> ephestia kuehniella</a>, <a href="https://publications.waset.org/abstracts/search?q=TEM" title=" TEM"> TEM</a> </p> <a href="https://publications.waset.org/abstracts/186062/repellent-activity-of-nanoemulsion-essential-oil-of-eucalyptus-globulus-labill-on-ephestia-kuehniella-lepidoptera-pyralidae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186062.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">49</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">16</span> Properties of Concrete with Wood Ashes in Construction Engineering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Piotr-Robert%20Lazik">Piotr-Robert Lazik</a>, <a href="https://publications.waset.org/abstracts/search?q=Lena%20Teichmann"> Lena Teichmann</a>, <a href="https://publications.waset.org/abstracts/search?q=Harald%20Garrecht"> Harald Garrecht</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many concrete technologists are looking for a solution to replace fly ashes as a component that occurs as a major component of many types of concrete. The importance of such a component is clear -it saves cement and reduces the amount of CO₂ in the atmosphere that occurs during cement production. For example, the amount of cement in ultrahigh strength concrete (UHPC) is approximately 700-800 kg/m³ in normal concrete up to 350 kg/m³. For this reason, it is easy to follow that the use of components like fly ashes or wood ashes protect the environment. The newest investigations carried out at the University of Stuttgart have clearly shown that the use of wood ashes with appropriate pre-treatment in concrete has a positive effect. German-wide, there are hundreds of tons of wood ashes, which can be used in a wide range of construction materials. The strengths of the concrete with different types of cement and with wood ashes have given the same or, in some cases, better results than those with the use of fly ashes. There are many areas in building construction, where the clays of wood ashes can be used as a by-product. This does not only require a strength test but also, for example, an examination of structural-physical parameters. Especially the heat and moisture characteristics have an important role in times of energy-efficient construction. These are therefore determined and then compared with the characteristics of the concretes with fly ashes. The University of Stuttgart has decided to investigate the buildings' physical properties of different types of concrete with wood ashes to find their application in construction. After the examination of the buildings' physical properties in combination with strength tests, it is possible to determine in which field of civil engineering, this type of concrete can be used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fly%20ashes" title="fly ashes">fly ashes</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20ashes" title=" wood ashes"> wood ashes</a>, <a href="https://publications.waset.org/abstracts/search?q=structural-physical%20parameters" title=" structural-physical parameters"> structural-physical parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=UHPC" title=" UHPC"> UHPC</a> </p> <a href="https://publications.waset.org/abstracts/118450/properties-of-concrete-with-wood-ashes-in-construction-engineering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118450.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">143</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">15</span> Role of Social Workers in Juvenile Justice Board as a Child Protection Mechanism for Children in Conflict with Law</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ida%20D.%20Souza">Ida D.

The vulnerability of children has increased due to emerging lifestyles, raising cost of living, higher expectations from adults, parental and care-giver stress /burn-out and a general raise in demand for services for children. A major area of concern is the rise of juvenile crimes in the overall crimes committed in the country. The UNCRC 1989 and JJ Act 2000 enables the structures to handle the juvenile children in care and concern in its real terms. One of the mechanisms to protect the children is the JJB a justice system. The aim is to hold a child culpable (guilty) for offence they committed, not through punishment, but counseling the child to understand their actions and persuade them away from such deviated activities in the future. The JJB consists of two social workers and a judicial magistrate and one of whom should be a woman. This study aims at understanding the role of social workers in best practices in deciding the best course of action for the rehabilitation of the child. Two case studies were carried out through in-depth interviews with the social worker member of the JJB of two Udupi and Mangalore districts. The best practices reported in which children are being allowed to express themselves in a child friendly environment and in the best interest of the child. The study highlighted team work to be very effective in understanding the child in their reformation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=child%20protection" title="child protection">child protection</a>, <a href="https://publications.waset.org/abstracts/search?q=best%20practices" title=" best practices"> best practices</a>, <a href="https://publications.waset.org/abstracts/search?q=juvenile%20justice" title=" juvenile justice"> juvenile justice</a>, <a href="https://publications.waset.org/abstracts/search?q=reformation%20teamwork" title=" reformation teamwork"> reformation teamwork</a> </p> <a href="https://publications.waset.org/abstracts/46489/role-of-social-workers-in-juvenile-justice-board-as-a-child-protection-mechanism-for-children-in-conflict-with-law" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46489.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">363</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">14</span> Family Caregiver Transitions and Health in Old Age: A Longitudinal Perspective </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Fagerstrom">Cecilia Fagerstrom</a>, <a href="https://publications.waset.org/abstracts/search?q=Solve%20Elmstahl"> Solve Elmstahl</a>, <a href="https://publications.waset.org/abstracts/search?q=Lena%20S.%20Wranker"> Lena S.

The role of family caregivers may well last for a long time but may also change over time, from being caregivers to being non-caregivers or vice versa. Although demands associated with family caring change as individuals enter into, engage with, and exit from this role, the evidence regarding the impact of family caregiving transitions on the health of older carers is still limited. This study comprised individuals (n=2294, 60+years) from the southern part of Sweden included in the project Swedish National study of Aging and Care. Caregiving transitions are discussed in the categories: enter, exit, and continuing during a six-year period. Individuals who exited caregiving during the time were older than those who continued or entered into the role of caregiving. At the six-year follow-up, caregivers who were continuing or had exited caregiving were more often worried about their own health compared to baseline. Resembling findings were not found in those who entered caregiving. Family caregiving transitions of exiting, entering or continuing had no effect on the individuals’ functional, physical and mental health expect for participants who entered in caregiving. For them, entering the role of family caregiving was associated with an improvement in physical health during the six years follow up period. Conclusion: Although the health impact of different caregiving transitions in late life does not differ, individual conditions and health at baseline are important parameters to take into consideration to improve long-term health in family caregivers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=family%20caregiving" title="family caregiving">family caregiving</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a>, <a href="https://publications.waset.org/abstracts/search?q=old%20age" title=" old age"> old age</a>, <a href="https://publications.waset.org/abstracts/search?q=transition" title=" transition"> transition</a> </p> <a href="https://publications.waset.org/abstracts/92388/family-caregiver-transitions-and-health-in-old-age-a-longitudinal-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92388.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">219</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">13</span> Correlation Between Ore Mineralogy and the Dissolution Behavior of K-Feldspar</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adrian%20Keith%20Caamino">Adrian Keith Caamino</a>, <a href="https://publications.waset.org/abstracts/search?q=Sina%20Shakibania"> Sina Shakibania</a>, <a href="https://publications.waset.org/abstracts/search?q=Lena%20Sunqvist-%C3%96qvist"> Lena Sunqvist-Öqvist</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Rosenkranz"> Jan Rosenkranz</a>, <a href="https://publications.waset.org/abstracts/search?q=Yousef%20Ghorbani"> Yousef Ghorbani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Feldspar minerals are one of the main components of the earth’s crust. They are tectosilicate, meaning that they mainly contain aluminum and silicon. Besides aluminum and silicon, they contain either potassium, sodium, or calcium. Accordingly, feldspar minerals are categorized into three main groups: K-feldspar, Na-feldspar, and Ca-feldspar. In recent years, the trend to use K-feldspar has grown tremendously, considering its potential to produce potash and alumina. However, the feldspar minerals, in general, are difficult to decompose for the dissolution of their metallic components. Several methods, including intensive milling, leaching under elevated pressure and temperature, thermal pretreatment, and the use of corrosive leaching reagents, have been proposed to improve its low dissolving efficiency. In this study, as part of the POTASSIAL EU project, to overcome the low dissolution efficiency of the K-feldspar components, mechanical activation using intensive milling followed by leaching using hydrochloric acid (HCl) was practiced. Grinding operational parameters, namely time, rotational speed, and ball-to-sample weight ratio, were studied using the Taguchi optimization method. Then, the mineralogy of the grinded samples was analyzed using a scanning electron microscope (SEM) equipped with automated quantitative mineralogy. After grinding, the prepared samples were subjected to HCl leaching. In the end, the dissolution efficiency of the main elements and impurities of different samples were correlated to the mineralogical characterization results. K-feldspar component dissolution is correlated with ore mineralogy, which provides insight into how to best optimize leaching conditions for selective dissolution. Further, it will have an effect on purifying steps taken afterward and the final value recovery procedures <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=K-feldspar" title="K-feldspar">K-feldspar</a>, <a href="https://publications.waset.org/abstracts/search?q=grinding" title=" grinding"> grinding</a>, <a href="https://publications.waset.org/abstracts/search?q=automated%20mineralogy" title=" automated mineralogy"> automated mineralogy</a>, <a href="https://publications.waset.org/abstracts/search?q=impurity" title=" impurity"> impurity</a>, <a href="https://publications.waset.org/abstracts/search?q=leaching" title=" leaching"> leaching</a> </p> <a href="https://publications.waset.org/abstracts/161198/correlation-between-ore-mineralogy-and-the-dissolution-behavior-of-k-feldspar" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161198.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">76</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">12</span> Meeting the Pedophile: Attitudes toward Pedophilia among Psychology Students </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rebecca%20Heron">Rebecca Heron</a>, <a href="https://publications.waset.org/abstracts/search?q=Julie%20Karsten"> Julie Karsten</a>, <a href="https://publications.waset.org/abstracts/search?q=Lena%20Schweikert"> Lena Schweikert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Adverse consequences of stigma towards pedophilia can, among other things, increase dynamic risk factors for sexual offending. Decreasing stigma, therefore, is a plausible approach in the attempt to prevent child sexual abuse. Stigma research suggests that providing direct contact to a stigmatized individual is the most efficient way of reducing stigma. The present study involved an educational intervention, followed by direct contact to a pedophile, to maximize effectiveness. It aimed at finding out whether a dichotomous anti-stigma intervention can change psychology students' attitudes towards pedophiles regarding perceived dangerousness, intentionality, deviance, and punitive attitudes. In a one sample pre-post design, 162 students of the University of Groningen attended a lecture about pedophilia, which was held by a psychology master’s student. Participants learned about child sex offending and pedophilia in addition to the importance of distinguishing between pedophiles and child sex offenders (CSOs). The guest lecturer Gabriel, shared his experiences about growing up, coping, and living with pedophilia. Results of the Wilcoxon signed-rank test revealed significantly diminished negative attitudes towards pedophiles after the intervention. Students perceived pedophiles as less dangerous, having less intent, and being less psychologically deviant. Additionally, students' punitive attitudes towards pedophiles diminished significantly. Also, a thematic analysis revealed that students were highly interested in the topic of pedophilia and greatly appreciative of Gabriel sharing his story. This study was the first to provide direct contact with a pedophile within an anti-stigma intervention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pedophilia" title="pedophilia">pedophilia</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-stigma%20intervention" title=" anti-stigma intervention"> anti-stigma intervention</a>, <a href="https://publications.waset.org/abstracts/search?q=punitive%20attitudes" title=" punitive attitudes"> punitive attitudes</a>, <a href="https://publications.waset.org/abstracts/search?q=attitude%20change" title=" attitude change "> attitude change </a> </p> <a href="https://publications.waset.org/abstracts/126556/meeting-the-pedophile-attitudes-toward-pedophilia-among-psychology-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126556.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">182</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">11</span> An Evaluation of Neuropsychiatric Manifestations in Systemic Lupus Erythematosus Patients in Saudi Arabia and Their Associated Factors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yousef%20M.%20Alammari">Yousef M.

Methods: During June 2021, this cross-sectional study was carried out among SLE patients in Saudi Arabia. The Saudi Rheumatism Association exploited social media platforms to provide a self-administered online questionnaire to SLE patients. All data analyses were performed using the Statistical Packages for Social Sciences (SPSS) version 26. Results: Two hundred and five SLE patients participated in the study (females 91.3 % vs. males 8.7 %). In addition, 13.5 % of patients had a family history of SLE, and 26% had SLE for one to three years. Alteration or loss of sensation (53.4%), Fear (52.4%), and headache (48.1%) were the most prevalent signs of neuropsychiatric symptoms in systemic lupus erythematosus (NPSLE) patients. The prevalence of patients with NPSLE was 40%. In a multivariate regression model, fear, altered sensations, cerebrovascular illness, sleep disruption, and diminished interest in routine activities were identified as independent risk variables for NPSLE. Conclusion: Nearly half of SLE patients demonstrated NP manifestations, with significant symptoms including fear, alteration of sensation, cerebrovascular disease, sleep disturbance, and reduced interest in normal activities. To detect the pathophysiology of NPSLE, it is necessary to understand the relationship between neuropsychiatric morbidity and other relevant rheumatic disorders in the SLE population. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neuropsychiatric" title="neuropsychiatric">neuropsychiatric</a>, <a href="https://publications.waset.org/abstracts/search?q=systemic%20lupus%20erythematosus" title=" systemic lupus erythematosus"> systemic lupus erythematosus</a>, <a href="https://publications.waset.org/abstracts/search?q=NPSLE" title=" NPSLE"> NPSLE</a>, <a href="https://publications.waset.org/abstracts/search?q=prevalence" title=" prevalence"> prevalence</a>, <a href="https://publications.waset.org/abstracts/search?q=SLE%20patients" title=" SLE patients"> SLE patients</a> </p> <a href="https://publications.waset.org/abstracts/167614/an-evaluation-of-neuropsychiatric-manifestations-in-systemic-lupus-erythematosus-patients-in-saudi-arabia-and-their-associated-factors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167614.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">75</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">10</span> German for Business Lawyers: A Practical Example of a German University of Applied Sciences </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Angelika%20Dorawa">Angelika Dorawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Lena%20Kreppel"> Lena Kreppel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Writing in the disciplines plays a major role at Universities. On the one hand, lectures look at the substance of assignments and on the other hand, they expect students to meet professional standards of layout and proofreading. However, the integration of writing concepts into the range of subjects is new to German Universities of Applied Sciences, which are focused on technical and scientific contexts. The Westphalian University of Applied Sciences (WH) established a successful program Talente_schreiben (Writing_Talents) that was funded by the Federal Ministry of Education and Research to improve written language skills for first-semester students at the WH. Besides having the main focus on basic language skills on all language levels, we also concentrate on subject-specific programs such as writing in the disciplines and are pioneers in this field in Germany. Since 2013, we started to include learning-to-write programs since first-semester students of Business Law studies must complete a writing assignment in the form and writing style of a legal opinion in order to fulfill their undergraduate degree requirements. To support our students at its best, our course for business lawyers focuses not only on the writing skills per se, but also on teaching both, the content and the particular discourse of the discipline. Hence, a specialist in German studies and a faculty tutor share the experience of processing, producing and reflecting a text. Whereas the German studies specialist refers to the rhetorical context such as orthography, grammar etc., the tutor acts as a guide on the side referring to the course content itself. In our presentation, we want to give an insight of the practice of a business law discipline, the combination of rhetoric and composition and discuss the methodological and didactic approaches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=German%20for%20business%20lawyers" title="German for business lawyers">German for business lawyers</a>, <a href="https://publications.waset.org/abstracts/search?q=talent%20development" title=" talent development"> talent development</a>, <a href="https://publications.waset.org/abstracts/search?q=pioneer%20program" title=" pioneer program"> pioneer program</a>, <a href="https://publications.waset.org/abstracts/search?q=Germany" title=" Germany"> Germany</a> </p> <a href="https://publications.waset.org/abstracts/59234/german-for-business-lawyers-a-practical-example-of-a-german-university-of-applied-sciences" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59234.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">325</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">9</span> The Influence of Microcapsulated Phase Change Materials on Thermal Performance of Geopolymer Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vinh%20Duy%20Cao">Vinh Duy Cao</a>, <a href="https://publications.waset.org/abstracts/search?q=Shima%20Pilehvar"> Shima Pilehvar</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20M.%20Szczotok"> Anna M.

One of the solutions to reduce the energy consumption for the building is to improve construction techniques and enhance material technology. Recently, microcapsulated phase change materials (MPCM) with high energy storage capacity within the phase transition temperature of the materials is a potential method to conserve and save energy. A new composite materials with high energy storage capacity by mixing MPCM into concrete for passive building technology is the promising candidate to reduce the energy consumption. One of the most untilized building materials for mixing with MPCM is Portland cement concrete. However, the emission of carbon dioxide (CO2) due to producing cement which plays the important role in the global warming is the main drawback of PCC. Accordingly, an environmentally friendly building material, geopolymer, which is synthesized by the reaction between the industrial waste material (aluminosilicate) and a strong alkali activator, is a potential materials to mixing with MPCM. Especially, the effect of MPCM on the thermal and mechanical properties of geopolymer concrete (GPC) is very limited. In this study, high thermal energy storage capacity materials were fabricated by mixing MPCM into geopolymer concrete. This article would investigate the effect of MPCM concentration on thermal and mechanical properties of GPC. The target is to balance the effect of MPCM on improving the thermal performance and maintaining the compressive strength of the geopolymer concrete at an acceptable level for building application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microencapsulated%20phase%20change%20materials" title="microencapsulated phase change materials">microencapsulated phase change materials</a>, <a href="https://publications.waset.org/abstracts/search?q=geopolymer%20concrete" title=" geopolymer concrete"> geopolymer concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20storage%20capacity" title=" energy storage capacity"> energy storage capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20performance" title=" thermal performance"> thermal performance</a> </p> <a href="https://publications.waset.org/abstracts/68879/the-influence-of-microcapsulated-phase-change-materials-on-thermal-performance-of-geopolymer-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68879.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">309</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">8</span> Millennial Teachers of Canada: Innovation within the Boxed-In Constraints of Tradition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lena%20Shulyakovskaya">Lena Shulyakovskaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Every year, schools aim to develop and adopt new technology and pedagogy as a way to equip today's students with the needed 21st Century skills. However, the field of primary and secondary education may not be as open to embracing change in reality. Despite the drive to reform and innovation, the field of education in Canada is still very much steeped in tradition and uses many of the practices that came into effect over 50 years ago. Among those are employment and retention practices. Millennials are the youngest generation of professionals entering the workplace at this time and the ones leaving their jobs within just a few years. Almost half of new teachers leave Canadian schools within their first five years on the job. This paper discusses one of the contributing factors that lead Canadian millennial teachers to either leave or stay in the profession - standardized education system. Using an exploratory case study approach, in-depth interviews with former and current millennial teachers were conducted to learn about their experiences within the K-12 system. Among the findings were the young teachers' concerns about the constant changes to teaching practices and technological implementations that claimed to advance teaching and learning, and yet in reality only disguised and reiterated the same traditional, outdated, and standardized practices that already existed. Furthermore, while many millennial teachers aspired to be innovative with their curriculum and teaching practices, they felt trapped and helpless in the hands of school leaders who were very reluctant to change. While many new program ideas and technological advancements are being made openly available to teachers on a regular basis, it is important to consider the education field as a whole and how it plays into the teachers' ability to realistically implement changes. By the year 2025, millennials will make up approximately 75% of the North American workforce. It is important to examine generational differences among teachers and understand how millennial teachers may be shaping the future of primary and secondary schools, either by staying or leaving the profession. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=21st%20century%20skills" title="21st century skills">21st century skills</a>, <a href="https://publications.waset.org/abstracts/search?q=millennials" title=" millennials"> millennials</a>, <a href="https://publications.waset.org/abstracts/search?q=teacher%20attrition" title=" teacher attrition"> teacher attrition</a>, <a href="https://publications.waset.org/abstracts/search?q=tradition" title=" tradition"> tradition</a> </p> <a href="https://publications.waset.org/abstracts/50121/millennial-teachers-of-canada-innovation-within-the-boxed-in-constraints-of-tradition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50121.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">228</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">7</span> Rheological Properties and Thermal Performance of Suspensions of Microcapsules Containing Phase Change Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vinh%20Duy%20Cao">Vinh Duy Cao</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Salas-Bringas"> Carlos Salas-Bringas</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20M.%20Szczotok"> Anna M.

Improved construction techniques and enhanced material technology can greatly reduce the energy consumption needed for the buildings. Microencapsulated phase change materials (MPCM) suspensions utilized as heat transfer fluids for energy storage and heat transfer applications provide promising potential solutions. A full understanding of the flow and thermal characteristics of microcapsule suspensions is needed to optimize the design of energy storage systems, in order to reduce the capital cost, system size, and energy consumption. The MPCM suspensions exhibited pseudoplastic and thixotropic behaviour, and significantly improved the thermal performance of the suspensions. Three different models were used to characterize the thixotropic behaviour of the MPCM suspensions: the second-order structural, kinetic model was found to give a better fit to the experimental data than the Weltman and Figoni-Shoemaker models. For all samples, the initial shear stress increased, and the breakdown rate accelerated significantly with increasing concentration. The thermal performance and rheological properties, especially the selection of rheological models, will be useful for developing the applications of microcapsules as heat transfer fluids in thermal energy storage system such as calculation of an optimum MPCM concentration, pumping power requirement, and specific power consumption. The effect of temperature on the shear thinning properties of the samples suggests that some of the phase change material is located outside the capsules, and contributes to agglomeration of the samples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=latent%20heat" title="latent heat">latent heat</a>, <a href="https://publications.waset.org/abstracts/search?q=microencapsulated%20phase%20change%20materials" title=" microencapsulated phase change materials"> microencapsulated phase change materials</a>, <a href="https://publications.waset.org/abstracts/search?q=pseudoplastic" title=" pseudoplastic"> pseudoplastic</a>, <a href="https://publications.waset.org/abstracts/search?q=suspension" title=" suspension"> suspension</a>, <a href="https://publications.waset.org/abstracts/search?q=thixotropic%20behaviour" title=" thixotropic behaviour"> thixotropic behaviour</a> </p> <a href="https://publications.waset.org/abstracts/53782/rheological-properties-and-thermal-performance-of-suspensions-of-microcapsules-containing-phase-change-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53782.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">266</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">6</span> Effective, Affordable, and Accessible Treatment for Pregnancy’s Commonest Complication: Online Synchronous Interpersonal Psychotherapy for Mothers with Postpartum Depression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vivian%20Polak">Vivian Polak</a>, <a href="https://publications.waset.org/abstracts/search?q=Lena%20Verdeli"> Lena Verdeli</a>, <a href="https://publications.waset.org/abstracts/search?q=Wendy%20Lou"> Wendy Lou</a>, <a href="https://publications.waset.org/abstracts/search?q=Caroline%20Lovett"> Caroline Lovett</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Postnatal depression (PND) is a common complication of childbirth that increases the risk of future depressive episodes in women, postpartum depression in partners, as well as social, emotional, behavioural, language, and cognitive problems in offspring. Although psychotherapy, and in particular Group Interpersonal Psychotherapy (IPT-G), has been proven effective in treating PND, it remains largely inaccessible. However, research has indicated that online synchronous group therapy can be equally as effective as in-person therapy and is a more affordable and accessible modality of treatment. This study aimed to ascertain whether delivering IPT-G virtually when compared to treatment as usual, could more effectively reduce depressive and anxiety symptoms, enhance mother-infant attachment, improve the couple relationship, augment social support, improve overall functioning, and enhance the quality of life for women in rural and northern Ontario who are suffering from PND. By bridging the gap in access to mental health services during the postpartum period, this study seeks to improve the well-being of mothers and their families in rural and northern Ontario, Canada. A randomized controlled trial was conducted to determine whether virtual IPT-G plus treatment as usual would be more effective than treatment as usual alone in treating women with PND in Ontario, Canada. Preliminary results indicate that women who received virtual IPT-G had a clinically and statistically significant decrease in overall depressive symptoms compared to their counterparts who received only the treatment as usual. As such, providing online synchronous IPT-G in the perinatal period not only has the potential to improve women's outcomes in the present but also to decrease future health costs, reduce the burden on the educational and justice systems, and decrease the number of disability life years lost to postnatal depression. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=family%20wellbeing" title="family wellbeing">family wellbeing</a>, <a href="https://publications.waset.org/abstracts/search?q=group%20psychotherapy" title=" group psychotherapy"> group psychotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=interpersonal%20psychotherapy" title=" interpersonal psychotherapy"> interpersonal psychotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=postnatal%20depression" title=" postnatal depression"> postnatal depression</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20psychotherapy" title=" virtual psychotherapy"> virtual psychotherapy</a> </p> <a href="https://publications.waset.org/abstracts/173774/effective-affordable-and-accessible-treatment-for-pregnancys-commonest-complication-online-synchronous-interpersonal-psychotherapy-for-mothers-with-postpartum-depression" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173774.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">68</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">5</span> A Simple Olfactometer for Odour and Lateralization Thresholds of Chemical Vapours</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lena%20Ernstg%C3%A5rd">Lena Ernstgård</a>, <a href="https://publications.waset.org/abstracts/search?q=Aishwarya%20M.%20Dwivedi"> Aishwarya M.

The delivery system consists of seven syringe pumps, each connected to a Tedlar bag containing a predefined concentration of the test chemical in the air. The seven pumps are connected to a 8-way mixing valve which in turn connects to a birhinal nose piece. Chemical vapor of known concentration is generated by injection of an appropriate amount of the test chemical into a Tedlar bag with a known volume of clean air. Complete vaporization is assured by gentle heating of the bag from the outside with a heat flow. The six test concentrations are obtained by adding different volumes from the starting bag to six new Tedlar bags with known volumes of clean air. One bag contains clean air only. Thus, six different test concentrations and clean air can easily be tested in series by shifting the valve to new positions. Initial in-line measurement with a photoionization detector showed that the delivery system quickly responded to a shift in valve position. Thus 90% of the desired concentration was reached within 15 seconds. The concentrations in the bags are verified daily by gas chromatography. The stability of the system in terms of chemical concentration is monitored in real time by means of a photo-ionization detector. To determine lateralization thresholds, an additional pump supplying clean air is added to the delivery system in a way so that the nostrils can be separately and interchangeably be exposed to clean air and test chemical. Odor and lateralization thresholds were determined for three aldehydes; acrolein, crotonaldehyde, and hexanal in 20 healthy naïve individuals. Aldehydes generally have a strong odour, and the selected aldehydes are also considered to be irritating to mucous membranes. The median odor thresholds of the three aldehydes were 0.017, 0.0008, and 0.097 ppm, respectively. No lateralization threshold could be identified for acrolein, whereas the medians for crotonaldehyde and hexanal were 0.003 and 0.39 ppm, respectively. In conclusion, we constructed a simple, inexpensive olfactometer that allows for stable and easily measurable concentrations of vapors of the test chemical. Our test with aldehydes demonstrates that the system produces valid detection among volunteers in terms of odour and lateralization thresholds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=irritation" title="irritation">irritation</a>, <a href="https://publications.waset.org/abstracts/search?q=odour%20delivery" title=" odour delivery"> odour delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=olfactometer" title=" olfactometer"> olfactometer</a>, <a href="https://publications.waset.org/abstracts/search?q=smell" title=" smell"> smell</a> </p> <a href="https://publications.waset.org/abstracts/58564/a-simple-olfactometer-for-odour-and-lateralization-thresholds-of-chemical-vapours" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58564.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">4</span> Ocean Planner: A Web-Based Decision Aid to Design Measures to Best Mitigate Underwater Noise</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Folegot">Thomas Folegot</a>, <a href="https://publications.waset.org/abstracts/search?q=Arnaud%20Levaufre"> Arnaud Levaufre</a>, <a href="https://publications.waset.org/abstracts/search?q=L%C3%A9na%20Bourven"> Léna Bourven</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Kermagoret"> Nicolas Kermagoret</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexis%20Caillard"> Alexis Caillard</a>, <a href="https://publications.waset.org/abstracts/search?q=Roger%20Gallou"> Roger Gallou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Concern for negative impacts of anthropogenic noise on the ocean’s ecosystems has increased over the recent decades. This concern leads to a similar increased willingness to regulate noise-generating activities, of which shipping is one of the most significant. Dealing with ship noise requires not only knowledge about the noise from individual ships, but also how the ship noise is distributed in time and space within the habitats of concern. Marine mammals, but also fish, sea turtles, larvae and invertebrates are mostly dependent on the sounds they use to hunt, feed, avoid predators, during reproduction to socialize and communicate, or to defend a territory. In the marine environment, sight is only useful up to a few tens of meters, whereas sound can propagate over hundreds or even thousands of kilometers. Directive 2008/56/EC of the European Parliament and of the Council of June 17, 2008 called the Marine Strategy Framework Directive (MSFD) require the Member States of the European Union to take the necessary measures to reduce the impacts of maritime activities to achieve and maintain a good environmental status of the marine environment. The Ocean-Planner is a web-based platform that provides to regulators, managers of protected or sensitive areas, etc. with a decision support tool that enable to anticipate and quantify the effectiveness of management measures in terms of reduction or modification the distribution of underwater noise, in response to Descriptor 11 of the MSFD and to the Marine Spatial Planning Directive. Based on the operational sound modelling tool Quonops Online Service, Ocean-Planner allows the user via an intuitive geographical interface to define management measures at local (Marine Protected Area, Natura 2000 sites, Harbors, etc.) or global (Particularly Sensitive Sea Area) scales, seasonal (regulation over a period of time) or permanent, partial (focused to some maritime activities) or complete (all maritime activities), etc. Speed limit, exclusion area, traffic separation scheme (TSS), and vessel sound level limitation are among the measures supported be the tool. Ocean Planner help to decide on the most effective measure to apply to maintain or restore the biodiversity and the functioning of the ecosystems of the coastal seabed, maintain a good state of conservation of sensitive areas and maintain or restore the populations of marine species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=underwater%20noise" title="underwater noise">underwater noise</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20biodiversity" title=" marine biodiversity"> marine biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20spatial%20planning" title=" marine spatial planning"> marine spatial planning</a>, <a href="https://publications.waset.org/abstracts/search?q=mitigation%20measures" title=" mitigation measures"> mitigation measures</a>, <a href="https://publications.waset.org/abstracts/search?q=prediction" title=" prediction"> prediction</a> </p> <a href="https://publications.waset.org/abstracts/157221/ocean-planner-a-web-based-decision-aid-to-design-measures-to-best-mitigate-underwater-noise" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157221.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">122</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">3</span> The Gut Microbiome in Cirrhosis and Hepatocellular Carcinoma: Characterization of Disease-Related Microbial Signature and the Possible Impact of Life Style and Nutrition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lena%20Lapidot">Lena Lapidot</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Amnon"> Amir Amnon</a>, <a href="https://publications.waset.org/abstracts/search?q=Rita%20Nosenko"> Rita Nosenko</a>, <a href="https://publications.waset.org/abstracts/search?q=Veitsman%20Ella"> Veitsman Ella</a>, <a href="https://publications.waset.org/abstracts/search?q=Cohen-Ezra%20Oranit"> Cohen-Ezra Oranit</a>, <a href="https://publications.waset.org/abstracts/search?q=Davidov%20Yana"> Davidov Yana</a>, <a href="https://publications.waset.org/abstracts/search?q=Segev%20Shlomo"> Segev Shlomo</a>, <a href="https://publications.waset.org/abstracts/search?q=Koren%20Omry"> Koren Omry</a>, <a href="https://publications.waset.org/abstracts/search?q=Safran%20Michal"> Safran Michal</a>, <a href="https://publications.waset.org/abstracts/search?q=Ben-Ari%20Ziv"> Ben-Ari Ziv</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Hepatocellular carcinoma (HCC) is one of the leading causes of cancer related mortality worldwide. Liver Cirrhosis is the main predisposing risk factor for the development of HCC. The factor(s) influencing disease progression from Cirrhosis to HCC remain unknown. Gut microbiota has recently emerged as a major player in different liver diseases, however its association with HCC is still a mystery. Moreover, there might be an important association between the gut microbiota, nutrition, life style and the progression of Cirrhosis and HCC. The aim of our study was to characterize the gut microbial signature in association with life style and nutrition of patients with Cirrhosis, HCC-Cirrhosis and healthy controls. Design: Stool samples were collected from 95 individuals (30 patients with HCC, 38 patients with Cirrhosis and 27 age, gender and BMI-matched healthy volunteers). All participants answered lifestyle and Food Frequency Questionnaires. 16S rRNA sequencing of fecal DNA was performed (MiSeq Illumina). Results: There was a significant decrease in alpha diversity in patients with Cirrhosis (qvalue=0.033) and in patients with HCC-Cirrhosis (qvalue=0.032) compared to healthy controls. The microbiota of patients with HCC-cirrhosis compared to patients with Cirrhosis, was characterized by a significant overrepresentation of Clostridium (pvalue=0.024) and CF231 (pvalue=0.010) and lower expression of Alphaproteobacteria (pvalue=0.039) and Verrucomicrobia (pvalue=0.036) in several taxonomic levels: Verrucomicrobiae, Verrucomicrobiales, Verrucomicrobiaceae and the genus Akkermansia (pvalue=0.039). Furthermore, we performed an analysis of predicted metabolic pathways (Kegg level 2) that resulted in a significant decrease in the diversity of metabolic pathways in patients with HCC-Cirrhosis (qvalue=0.015) compared to controls, one of which was amino acid metabolism. Furthermore, investigating the life style and nutrition habits of patients with HCC-Cirrhosis, we found significant correlations between intake of artificial sweeteners and Verrucomicrobia (qvalue=0.12), High sugar intake and Synergistetes (qvalue=0.021) and High BMI and the pathogen Campylobacter (qvalue=0.066). Furthermore, overweight in patients with HCC-Cirrhosis modified bacterial diversity (qvalue=0.023) and composition (qvalue=0.033). Conclusions: To the best of the our knowledge, we present the first report of the gut microbial composition in patients with HCC-Cirrhosis, compared with Cirrhotic patients and healthy controls. We have demonstrated in our study that there are significant differences in the gut microbiome of patients with HCC-cirrhosis compared to Cirrhotic patients and healthy controls. Our findings are even more pronounced because the significantly increased bacteria Clostridium and CF231 in HCC-Cirrhosis weren't influenced by diet and lifestyle, implying this change is due to the development of HCC. Further studies are needed to confirm these findings and assess causality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cirrhosis" title="Cirrhosis">Cirrhosis</a>, <a href="https://publications.waset.org/abstracts/search?q=Hepatocellular%20carcinoma" title=" Hepatocellular carcinoma"> Hepatocellular carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20style" title=" life style"> life style</a>, <a href="https://publications.waset.org/abstracts/search?q=liver%20disease" title=" liver disease"> liver disease</a>, <a href="https://publications.waset.org/abstracts/search?q=microbiome" title=" microbiome"> microbiome</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrition" title=" nutrition"> nutrition</a> </p> <a href="https://publications.waset.org/abstracts/96178/the-gut-microbiome-in-cirrhosis-and-hepatocellular-carcinoma-characterization-of-disease-related-microbial-signature-and-the-possible-impact-of-life-style-and-nutrition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96178.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">129</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">2</span> Associations Between Pornography Use Motivations and Sexual Satisfaction in Gender Diverse and Cisgender Individuals in the 43-Country International Sex Survey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aur%C3%A9lie%20Michaud">Aurélie Michaud</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%89milie%20Gaudet"> Émilie Gaudet</a>, <a href="https://publications.waset.org/abstracts/search?q=M%C3%B3nika%20Ko%C3%B3s"> Mónika Koós</a>, <a href="https://publications.waset.org/abstracts/search?q=L%C3%A9na%20Nagy"> Léna Nagy</a>, <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20Demetrovics"> Zsolt Demetrovics</a>, <a href="https://publications.waset.org/abstracts/search?q=Shane%20W.%20Kraus"> Shane W.

Prior studies have assessed the associations between pornography use frequency and sexual satisfaction, in cisgender and heterosexual individuals, with mixed results. However, measuring pornography use solely by pornography use frequency is problematic, as it can lead to disregarding important contextual factors that may be related to pornography use’s potential effects. Pornography use motivations (PUMs) represent key predictors of sexual behaviors. Yet, their associations with different indicators of sexual wellbeing have yet to be extensively studied. This cross-cultural study examined the links between the eight PUMs most often reported in the general population (i.e. sexual pleasure, sexual curiosity, emotional distraction or suppression, fantasy, stress reduction, boredom avoidance, lack of sexual satisfaction, and self-exploration) and sexual satisfaction in gender diverse and cisgender individuals. Given the lack of scientific data on associations between individuals’ PUMs and sexual satisfaction, these links were examined in an exploratory manner. A total of 43 countries from five continents were included in the International Sex Survey (ISS). A secure online platform was used to collect self-report, anonymous data from 82,243 participants (39.6% men, 57% women, 3.4% gender diverse individuals; M = 32.4 years, SD = 12.5). Gender-based differences in levels of sexual pleasure, sexual curiosity, emotional distraction, fantasy, stress reduction, boredom avoidance, lack of sexual satisfaction, and self-exploration PUMs were examined using one-way ANOVAs. Then, for each gender group, the associations between each PUM and sexual satisfaction were examined using multiple linear regression, controlling for frequency of masturbation. One-way ANOVAs indicated significant differences between men, women, and gender diverse individuals on all PUMs. For sexual pleasure, sexual curiosity, fantasy, boredom avoidance, lack of sexual satisfaction, emotional distraction, and stress reduction PUMs, men showed the highest scores, followed by gender-diverse individuals, and women. However, for self-exploration, gender-diverse individuals had higher average scores than men. For all PUMs, women’s average scores were the lowest. After controlling for frequency of masturbation, for all genders, sexual pleasure, sexual curiosity and boredom avoidance were significant positive predictors of sexual satisfaction, while lack of sexual satisfaction PUM was a significant negative predictor. Fantasy, stress reduction and self-exploration PUMs were positive significant predictors of sexual satisfaction, and fantasy was a negative significant predictor, but only for women. Findings highlight important gender differences in regards to the main motivations underlying pornography use and their relations to sexual satisfaction. While men and gender diverse individuals show similar motivation profiles, woman report a particularly unique experience, with fantasy, stress reduction and self-exploration being associated to their sexual satisfaction. This work outlines the importance of considering the role of pornography use motivations when studying the links between pornography viewing and sexual well-being, and may provide basis for gender-based considerations when working with individuals seeking help for their pornography use or sexual satisfaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pornography" title="pornography">pornography</a>, <a href="https://publications.waset.org/abstracts/search?q=sexual%20satifsaction" title=" sexual satifsaction"> sexual satifsaction</a>, <a href="https://publications.waset.org/abstracts/search?q=cross-cultural" title=" cross-cultural"> cross-cultural</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20diversity" title=" gender diversity"> gender diversity</a> </p> <a href="https://publications.waset.org/abstracts/159509/associations-between-pornography-use-motivations-and-sexual-satisfaction-in-gender-diverse-and-cisgender-individuals-in-the-43-country-international-sex-survey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159509.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">106</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">1</span> Microbial Biogeography of Greek Olive Varieties Assessed by Amplicon-Based Metagenomics Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lena%20Payati">Lena Payati</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Kazou"> Maria Kazou</a>, <a href="https://publications.waset.org/abstracts/search?q=Effie%20Tsakalidou"> Effie Tsakalidou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Table olives are one of the most popular fermented vegetables worldwide, which along with olive oil, have a crucial role in the world economy. They are highly appreciated by the consumers for their characteristic taste and pleasant aromas, while several health and nutritional benefits have been reported as well. Until recently, microbial biogeography, i.e., the study of microbial diversity over time and space, has been mainly associated with wine. However, nowadays, the term 'terroir' has been extended to other crops and food products so as to link the geographical origin and environmental conditions to quality aspects of fermented foods. Taking the above into consideration, the present study focuses on the microbial fingerprinting of the most important olive varieties of Greece with the state-of-the-art amplicon-based metagenomics analysis. Towards this, in 2019, 61 samples from 38 different olive varieties were collected at the final stage of ripening from 13 well spread geographical regions in Greece. For the metagenomics analysis, total DNA was extracted from the olive samples, and the 16S rRNA gene and ITS DNA region were sequenced and analyzed using bioinformatics tools for the identification of bacterial and yeasts/fungal diversity, respectively. Furthermore, principal component analysis (PCA) was also performed for data clustering based on the average microbial composition of all samples from each region of origin. According to the composition, results obtained, when samples were analyzed separately, the majority of both bacteria (such as Pantoea, Enterobacter, Roserbergiella, and Pseudomonas) and yeasts/fungi (such as Aureobasidium, Debaromyces, Candida, and Cladosporium) genera identified were found in all 61 samples. Even though interesting differences were observed at the relative abundance level of the identified genera, the bacterial genus Pantoea and the yeast/fungi genus Aureobasidium were the dominant ones in 35 and 40 samples, respectively. Of note, olive samples collected from the same region had similar fingerprint (genera identified and relative abundance level) regardless of the variety, indicating a potential association between the relative abundance of certain taxa and the geographical region. When samples were grouped by region of origin, distinct bacterial profiles per region were observed, which was also evident from the PCA analysis. This was not the case for the yeast/fungi profiles since 10 out of the 13 regions were grouped together mainly due to the dominance of the genus Aureobasidium. A second cluster was formed for the islands Crete and Rhodes, both of which are located in the Southeast Aegean Sea. These two regions clustered together mainly due to the identification of the genus Toxicocladosporium in relatively high abundances. Finally, the Agrinio region was separated from the others as it showed a completely different microbial fingerprinting. However, due to the limited number of olive samples from some regions, a subsequent PCA analysis with more samples from these regions is expected to yield in a more clear clustering. The present study is part of a bigger project, the first of its kind in Greece, with the ultimate goal to analyze a larger set of olive samples of different varieties and from different regions in Greece in order to have a reliable olives’ microbial biogeography. <p class="card-text"><strong>Keywords:</strong> <a
