Most of the research has been on school leadership. While research has focused on the role of leadership on school improvement, little research has examined what variables the top elementary schools have in common. To undertake school improvement, it is important to understand what factors the best schools share. The purpose of this study was to examine data of the “Best Elementary Schools in California,” based on academic achievement as rated by three prominent websites and determine if these schools had any common factors which were different than the statewide averages. The variables examined included access to subject matter specialists (physical education, art, and music), librarians, after school programs, class size, socioeconomic status, and diversity. The participants consisted of the top public elementary schools in California based on the websites i)https://www.niche.com/k12/search/best-schools/, ii)https://www.finder.com/best-schools-california,and iii)https://www.schooldigger.com/go/CA/schoolrank.aspx. The data for subject matter specialists (physical education, art, and music), librarians, after school programs, class size, socioeconomic status, and diversity were collected from these top schools and compared to California statewide averages. Results indicate that top public elementary schools in California have a high number of subject matter specialists that teach physical education, art, and music. These positions are on the decline in the average public elementary school in California, but the top schools have abundant access to these specialists. The physical education specialist has the highest statistically significant difference between the nationwide average and the top schools—librarians, and after school programs are also most commonly high in top public elementary schools in California. The high presence of these programs may be aiding academic achievement in less visible ways. Class size is small, socio-economic status is high, and diversity is low among top public elementary schools in California when compared to the statewide average public elementary schools in California. The single largest area of discrepancy was between physical education specialists in a top school and their state and nationwide averages. The socioeconomic status of schools and parents may be an underlining factor affecting several other variables. This affluence could explain how these schools were able to have access to subject matter specialists, after-school activities, and, therefore, more opportunities for physical activity and greater learning opportunities affecting academic achievement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=academic%20achievement" title="academic achievement">academic achievement</a>, <a href="https://publications.waset.org/abstracts/search?q=elementary%20education" title=" elementary education"> elementary education</a>, <a href="https://publications.waset.org/abstracts/search?q=factors" title=" factors"> factors</a>, <a href="https://publications.waset.org/abstracts/search?q=schools" title=" schools"> schools</a> </p> <a href="https://publications.waset.org/abstracts/114838/comparison-of-the-common-factors-of-the-top-academic-elementary-schools-to-the-average-elementary-schools-in-california-looking-beyond-school-leadership" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114838.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">133</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> Effectiveness of Computer Video Games on the Levels of Anxiety of Children Scheduled for Tooth Extraction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marji%20Umil">Marji Umil</a>, <a href="https://publications.waset.org/abstracts/search?q=Miane%20Karyle%20Urolaza"> Miane Karyle Urolaza</a>, <a href="https://publications.waset.org/abstracts/search?q=Ian%20Winston%20Dale%20Uy"> Ian Winston Dale Uy</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Charle%20Magne%20Valdez"> John Charle Magne Valdez</a>, <a href="https://publications.waset.org/abstracts/search?q=Karen%20Elizabeth%20Valdez"> Karen Elizabeth Valdez</a>, <a href="https://publications.waset.org/abstracts/search?q=Ervin%20Charles%20Valencia"> Ervin Charles Valencia</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheryleen%20Tan-Chua"> Cheryleen Tan-Chua</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Distraction techniques can be successful in reducing the anxiety of children during medical procedures. Dental procedures, in particular, are associated with dental anxiety which has been identified as a significant and common problem in children, however, only limited studies were conducted to address such problem. Thus, this study determined the effectiveness of computer video games on the levels of anxiety of children between 5-12 years old scheduled for tooth extraction. Methods: A pre-test post-test quasi-experimental study was conducted involving 30 randomly-assigned subjects, 15 in the experimental and 15 in the control. Subjects in the experimental group played computer video games for a maximum of 15 minutes, however, no intervention was done on the control. The modified Yale Pre-operative Anxiety Scale (m-YPAS) with a Cronbach’s alpha of 0.9 was used to assess anxiety at two different points: upon arrival in the clinic (pre-test anxiety) and 15 minutes after the first measurement (post-test anxiety). Paired t-test and ANCOVA were used to analyze the gathered data. Results: Results showed that there is a significant difference between the pre-test and post-test anxiety scores of the control group (p=0.0002) which indicates an increased anxiety. A significant difference was also noted between the pre-test and post-test anxiety scores of the experimental group (p=0.0002) which indicates decreased anxiety. Comparatively, the experimental group showed lower anxiety score (p=<0.0001) than the control. Conclusion: The use of computer video games is effective in reducing the pre-operative anxiety among children and can be an alternative non-pharmacological management in giving pre-operative care. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=play%20therapy" title="play therapy">play therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=preoperative%20anxiety" title=" preoperative anxiety"> preoperative anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=tooth%20extraction" title=" tooth extraction"> tooth extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=video%20games" title=" video games"> video games</a> </p> <a href="https://publications.waset.org/abstracts/21257/effectiveness-of-computer-video-games-on-the-levels-of-anxiety-of-children-scheduled-for-tooth-extraction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21257.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">452</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">22</span> Mobile Smart Application Proposal for Predicting Calories in Food</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcos%20Valdez%20Alexander%20Junior">Marcos Valdez Alexander Junior</a>, <a href="https://publications.waset.org/abstracts/search?q=Igor%20Aguilar-Alonso"> Igor Aguilar-Alonso</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Malnutrition is the root of different diseases that universally affect everyone, diseases such as obesity and malnutrition.

Most institutions at least in Mexico, pay low attention to the types of motivation students have when they are studying English; however, considering the motivation they have, may lead to better understanding about their needs and purposes for learning English and the professors may understand and focus on their interests for making them persist in action through the course. This topic has been widely investigated in different countries, but more research needs to be done in Mexico to shed light on this area of potential impact. The aim of this research is to focus on the types of motivation, intrinsic and extrinsic, instrumental and integrative and the attitudes students have about English language to identify aspects that are alike to other contexts and research areas based on the theory of Dörnyei (2013) and Gardner (2001). It was carried out at a Mexican University in a small village in Quintana Roo. The potential implications, the findings as well as the limitations are presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attides%20of%20motivation" title="attides of motivation">attides of motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=factors%20of%20motivation" title=" factors of motivation"> factors of motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=extrinsic%20and%20intrinsic%20motivation" title=" extrinsic and intrinsic motivation"> extrinsic and intrinsic motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=instrumental%20and%20integrative%20motivation" title=" instrumental and integrative motivation"> instrumental and integrative motivation</a> </p> <a href="https://publications.waset.org/abstracts/157373/types-of-motivation-at-a-rural-university" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157373.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">89</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Context-Aware Recommender System Using Collaborative Filtering, Content-Based Algorithm and Fuzzy Rules</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xochilt%20Ramirez-Garcia">Xochilt Ramirez-Garcia</a>, <a href="https://publications.waset.org/abstracts/search?q=Mario%20Garcia-Valdez"> Mario Garcia-Valdez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Contextual recommendations are implemented in Recommender Systems to improve user satisfaction, recommender system makes accurate and suitable recommendations for a particular situation reaching personalized recommendations.

More research is needed to fully understand the EXO characteristics and mechanisms of EXO-mediated wound healing, especially wound healing after burn injury. Methods: Total EXOs were isolated from 85 serum samples of 29 burn patients and 13 healthy individuals. We characterized the EXOs for morphology and density, serum concentration, protein level, marker expression, size distribution, and cytokine content. After confirmation of EXO uptake by dermal fibroblasts, we also explored functional regulation of primary human normal skin and hypertrophic scar fibroblast cell lines by the EXOs in vitro, including cell proliferation and apoptosis. Results: EXOs dynamically changed their morphology, density, size, and cytokine level during wound healing in burn patients, which were correlated with burn severity and the stages of wound healing. EXOs from both burn patients and healthy individuals stimulated dermal fibroblast proliferation and apoptosis. Conclusion: EXO features may be important signals that influence wound healing after burn injury; however, to understand the mechanisms by which EXOs regulated the fibroblasts in healing wounds, further studies will be required in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=exosome" title="exosome">exosome</a>, <a href="https://publications.waset.org/abstracts/search?q=burn" title=" burn"> burn</a>, <a href="https://publications.waset.org/abstracts/search?q=wound%20healing" title=" wound healing"> wound healing</a>, <a href="https://publications.waset.org/abstracts/search?q=hypertrophic%20scarring" title=" hypertrophic scarring"> hypertrophic scarring</a>, <a href="https://publications.waset.org/abstracts/search?q=cytokines" title=" cytokines"> cytokines</a> </p> <a href="https://publications.waset.org/abstracts/170905/characteristics-of-serum-exosomes-after-burn-injury-and-dermal-fibroblast-regulation-by-exosomes-in-vitro" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170905.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">81</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> Understanding Cruise Passengers’ On-board Experience throughout the Customer Decision Journey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabina%20Akter">Sabina Akter</a>, <a href="https://publications.waset.org/abstracts/search?q=Osiris%20Valdez%20Banda"> Osiris Valdez Banda</a>, <a href="https://publications.waset.org/abstracts/search?q=Pentti%20Kujala"> Pentti Kujala</a>, <a href="https://publications.waset.org/abstracts/search?q=Jani%20Romanoff"> Jani Romanoff </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper examines the relationship between on-board environmental factors and customer overall satisfaction in the context of the cruise on-board experience.

This study reveals the cruise passengers’ on-board experience through the customer decision journey based on the publicly available data. Pearson correlation and regression analysis have been applied, and the results show a positive and a significant relationship between the environmental factors and on-board experience. These data help understand the cruise passengers’ on-board experience, which will be used for the ultimate decision-making process in cruise ship design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cruise%20behavior" title="cruise behavior">cruise behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=customer%20activities" title=" customer activities"> customer activities</a>, <a href="https://publications.waset.org/abstracts/search?q=on-board%20environmental%20factors" title=" on-board environmental factors"> on-board environmental factors</a>, <a href="https://publications.waset.org/abstracts/search?q=on-board%20experience" title=" on-board experience"> on-board experience</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20or%20customer%20satisfaction" title=" user or customer satisfaction"> user or customer satisfaction</a> </p> <a href="https://publications.waset.org/abstracts/132154/understanding-cruise-passengers-on-board-experience-throughout-the-customer-decision-journey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132154.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">168</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> Working in Multidisciplinary Care Teams: Perspectives from Health Care and Social Service Providers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lindy%20Van%20Vliet">Lindy Van Vliet</a>, <a href="https://publications.waset.org/abstracts/search?q=Saloni%20Phadke"> Saloni Phadke</a>, <a href="https://publications.waset.org/abstracts/search?q=Anthea%20Nelson"> Anthea Nelson</a>, <a href="https://publications.waset.org/abstracts/search?q=Ann%20Gallant"> Ann Gallant</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Holistic and patient-centred palliative care and support require an integrated system of care that includes health and social service providers working together to ensure that patients and families have access to the care they need. The objective of this study is to further explore and understand the benefits and challenges of mobilizing multidisciplinary care teams for health care professionals and social service providers. Drawing on an interpretivist, exploratory, qualitative design, our multidisciplinary research team (medicine, nursing and social work) conducted interviews with 15 health care and social service providers in the Ottawa region. Interview data was audio-recorded, transcribed, and analyzed using a reflexive thematic analysis approach. The data deepens our understandings of the facilitators and barriers posed by multidisciplinary care teams. Three main findings emerged: First, the data highlighted the benefits of multidisciplinary care teams for both patient outcomes and quality of life and provider mental health; second, the data showed that the lack of a system-wide integrated communication system reduces the quality of patient care and increases provider stress while working in multidisciplinary care teams; finally, the data demonstrated the existence of implicit hierarchies between disciplines, this coupled with different disciplinary perspectives of palliative care provision can lead to friction and challenges within care teams. These findings will have important implications for the future of palliative care as they will help to facilitate and build stronger person-centred/relationship-centred palliative care practices by naming the challenges faced by multidisciplinary palliative care teams and providing examples of best practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=public%20health%20palliative%20care" title="public health palliative care">public health palliative care</a>, <a href="https://publications.waset.org/abstracts/search?q=palliative%20care%20nursing" title=" palliative care nursing"> palliative care nursing</a>, <a href="https://publications.waset.org/abstracts/search?q=care%20networks" title=" care networks"> care networks</a>, <a href="https://publications.waset.org/abstracts/search?q=integrated%20health%20care" title=" integrated health care"> integrated health care</a>, <a href="https://publications.waset.org/abstracts/search?q=palliative%20care%20approach" title=" palliative care approach"> palliative care approach</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20health" title=" public health"> public health</a>, <a href="https://publications.waset.org/abstracts/search?q=multidisciplinary%20work" title=" multidisciplinary work"> multidisciplinary work</a>, <a href="https://publications.waset.org/abstracts/search?q=care%20teams" title=" care teams"> care teams</a> </p> <a href="https://publications.waset.org/abstracts/160258/working-in-multidisciplinary-care-teams-perspectives-from-health-care-and-social-service-providers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160258.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">82</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> The Role of Spiritual Experience, Gerotranscendence and Social Engagement on Successful Aging among Incarcerated Filipino Elderly: A Structural Equation Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Les%20Paul%20Valdez">Les Paul Valdez</a>, <a href="https://publications.waset.org/abstracts/search?q=Rowena%20Manzarate"> Rowena Manzarate</a>, <a href="https://publications.waset.org/abstracts/search?q=Joseph%20Carl%20Lunizo"> Joseph Carl Lunizo</a>, <a href="https://publications.waset.org/abstracts/search?q=Mary%20Thereze%20Mabaquiao"> Mary Thereze Mabaquiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Mary%20Deo%20Luigi%20Mabunay"> Mary Deo Luigi Mabunay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Across the literature, varying definitions of successful aging can be found. As a result, several determinants have been associated with successful aging. However, there is a paucity of literature exploring the relationship between successful aging and factors such as spiritual experience, gerotranscendence, and social engagement. Objective: Thus, this study purports to ascertain the relationship between and among spiritual experience, gerotranscendence, social engagement and successful aging. Methods: The Daily Spiritual Experience Scale (DSES), Social Engagement Scale (SES), Gerotranscendence Scale Revised (GS-R) and Expectations Regarding Aging (ERA) were fielded to 349 incarcerated elderly to measure spiritual experience, social engagement, gerotranscendence and successful aging respectively. Data was analyzed using Structural Equation Modelling through AMOS 21. The hypothesized model was evaluated using the goodness of fit and parsimony indices. Results: Social engagement (β= .179, p=.128) and spiritual experience (β= .375, p=.262) contribute to successful aging through the mediating effect of gerotranscendence (β= .973, p=.718). Conclusion: Today more than ever, healthcare providers in penal institutions are challenged to ensure that incarcerated elderly are socially and spiritually engaged; and have high levels of gerotranscendence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=elderly" title="elderly">elderly</a>, <a href="https://publications.waset.org/abstracts/search?q=Filipino" title=" Filipino"> Filipino</a>, <a href="https://publications.waset.org/abstracts/search?q=gerotranscendence" title=" gerotranscendence"> gerotranscendence</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20engagement" title=" social engagement"> social engagement</a>, <a href="https://publications.waset.org/abstracts/search?q=spiritual%20experience" title=" spiritual experience"> spiritual experience</a>, <a href="https://publications.waset.org/abstracts/search?q=successful%20aging" title=" successful aging "> successful aging </a> </p> <a href="https://publications.waset.org/abstracts/46006/the-role-of-spiritual-experience-gerotranscendence-and-social-engagement-on-successful-aging-among-incarcerated-filipino-elderly-a-structural-equation-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46006.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">521</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> The Impact of Nutrition Education Intervention in Improving the Nutritional Status of Sickle Cell Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lindy%20Adoma%20Dampare">Lindy Adoma Dampare</a>, <a href="https://publications.waset.org/abstracts/search?q=Marina%20Aferiba%20Tandoh"> Marina Aferiba Tandoh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sickle cell disease (SCD) is an inherited blood disorder that mostly affects individuals in sub-Saharan Africa. Nutritional deficiencies have been well established in SCD patients. In Ghana, studies have revealed the prevalence of malnutrition, especially amongst children with SCD and hence the need to develop an evidence-based comprehensive nutritional therapy for SCD to improve their nutritional status. The aim of the study was to develop and assess the effect of a nutrition education material on the nutritional status of SCD patients in Ghana. This was a pre-post interventional study. Patients between the ages of 2 to 60 years were recruited from the Tema General Hospital. Following a baseline nutrition knowledge (NK), beliefs, sanitary practice and dietary consumption pattern assessment, a twice-monthly nutrition education was carried out for 3 months, followed by a post-intervention assessment. Nutritional status of SCD patients was assessed using a 3-days dietary recall and anthropometric measurements. Nutrition education (NE) was given to SCD adults and caregivers of SCD children. Majority of the caregivers (69%) and SCD adult (82%) at baseline had low NK. The level of NK improved significantly in SCD adults (4.18±1.83 vs. 10.00±1.00, p<0.001) and caregivers (5.58 ± 2.25 vs.10.44± 0.846, p<0.001) after NE. Increase in NK improved dietary intake and dietary consumption pattern of SCD patients. Significant increase in weight (23.2±11.6 vs. 25.9±12.1, p=0.036) and height (118.5±21.9 vs. 123.5±22.2, p=0.011) was observed in SCD children at post intervention. Stunting (10.5% vs. 8.6%, p=0.62) and wasting (22.1% vs. 14.4%, p=0.30) reduced in SCD children after NE although not statistically significant. Reduction (18.2% vs. 9.1%) in underweight and an increase (18.2% vs. 27.3%) in overweight SCD adults was recorded at post intervention. Fat mass remained the same while high muscle mass increased (18.2% vs. 27.3%) at post intervention in SCD adult. Anaemic status of SCD patients improved at post intervention and the improvement was statistically significant amongst SCD children. Nutrition education improved the NK of SCD caregivers and adults hence, improving the dietary consumption pattern and nutrient intake of SCD patients. Overall, NE improved the nutritional status of SCD patients. This study shows the potential of nutrition education in improving the nutritional knowledge, dietary consumption pattern, dietary intake and nutritional status of SCD patients, and should be further explored. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sickle%20cell%20disease" title="sickle cell disease">sickle cell disease</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrition%20education" title=" nutrition education"> nutrition education</a>, <a href="https://publications.waset.org/abstracts/search?q=dietary%20intake" title=" dietary intake"> dietary intake</a>, <a href="https://publications.waset.org/abstracts/search?q=nutritional%20status" title=" nutritional status"> nutritional status</a> </p> <a href="https://publications.waset.org/abstracts/167137/the-impact-of-nutrition-education-intervention-in-improving-the-nutritional-status-of-sickle-cell-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167137.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">102</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> Building Care Networks for Patients with Life-Limiting Illnesses: Perspectives from Health Care and Social Service Providers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lindy%20Van%20Vliet">Lindy Van Vliet</a>, <a href="https://publications.waset.org/abstracts/search?q=Saloni%20Phadke"> Saloni Phadke</a>, <a href="https://publications.waset.org/abstracts/search?q=Anthea%20Nelson"> Anthea Nelson</a>, <a href="https://publications.waset.org/abstracts/search?q=Ann%20Gallant"> Ann Gallant</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Comprehensive and compassionate palliative care and support requires an integrated system of care that draws on formal health and social service providers working together with community and informal networks to ensure that patients and families have access to the care they need. The objective of this study is to further explore and understand the community supports, services, and informal networks that health care professionals and social service providers rely on to allow their patients to die in their homes and communities. Drawing on an interpretivist, exploratory, qualitative design, our multidisciplinary research team (medicine, nursing and social work) conducted interviews with 15 health care and social service providers in the Ottawa region. Interview data was audio-recorded, transcribed and analyzed using a reflexive thematic analysis approach. The data deepens our understandings of the facilitators and barriers that arise as health care and social service providers attempt to build networks of care for patients with life limiting illnesses and families. Three main findings emerged: First, the variability that arises due to systemic barriers in accessing and providing care; second, the exceptionally challenging workload that providers are facing as they work to address complex social care needs (housing, disability, food security), along with escalating palliative care needs; and, finally, the lack of structural support that providers and informal care networks receive. Conclusion: These findings will facilitate and build stronger person-centred/relationship-centred principles and practices between providers, patients, community, and informal care networks by highlighting the systemic barriers to accessing and providing person-centred care. Further, they will have important implications for future partnerships in integrated care delivery programs and initiatives, community policies, education programs, and provincial and national palliative care strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=public%20health%20palliative%20care" title="public health palliative care">public health palliative care</a>, <a href="https://publications.waset.org/abstracts/search?q=palliative%20care%20nursing" title=" palliative care nursing"> palliative care nursing</a>, <a href="https://publications.waset.org/abstracts/search?q=care%20networks" title=" care networks"> care networks</a>, <a href="https://publications.waset.org/abstracts/search?q=informal%20care" title=" informal care"> informal care</a>, <a href="https://publications.waset.org/abstracts/search?q=integrated%20health%20care" title=" integrated health care"> integrated health care</a> </p> <a href="https://publications.waset.org/abstracts/157559/building-care-networks-for-patients-with-life-limiting-illnesses-perspectives-from-health-care-and-social-service-providers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157559.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">96</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> Cultural Factors Associated with Male Criminal Behavior and Inmate Population</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patricia%20Martinez%20Lanz">Patricia Martinez Lanz</a>, <a href="https://publications.waset.org/abstracts/search?q=Patricia%20Hernandez%20Valdez"> Patricia Hernandez Valdez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Over the last decade, crime has reached unprecedented levels and has caused much violent death in Mexico. To establish factors that potentially can facilitate crime, as well as the status of the emotional wellbeing presented in prison population, the present study was realized with a sample composed of 299 inmates of the Federal Center for Social Reinsertion in Oaxaca, Mexico. A questionnaire was specifically developed designed and applied to this population, evaluating sociodemographic factors and four Likert scales: substance consumption (drugs and alcohol), domestic violence and depressive symptoms. Reliability was adequate (Cronbach's Alpha= .703) and validity of the instrument showed appropriate relations between the reagents of each scale. Results showed through Chi Square analysis, statistically significant differences in the correlations between sociodemographic factors, domestic violence, addictions and depressive symptoms. Results reported that most of the inmates were between 28 and 47 years old (51.8%), had a low educational level (elementary school 42.5%), were in consensual union (42.5%), had high and severe levels of alcohol consumption (43.5% of the cases) and reported the presence of high and severe level of depression (28.9% of the cases). The results of this research are part of a national study of all Federal Centers for Social Reinsertion System in Mexico, in order to developed intervention strategies used in prison to prevent crime. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=delinquency" title="delinquency">delinquency</a>, <a href="https://publications.waset.org/abstracts/search?q=addictions" title=" addictions"> addictions</a>, <a href="https://publications.waset.org/abstracts/search?q=violence" title=" violence"> violence</a>, <a href="https://publications.waset.org/abstracts/search?q=depression" title=" depression"> depression</a>, <a href="https://publications.waset.org/abstracts/search?q=crime" title=" crime"> crime</a>, <a href="https://publications.waset.org/abstracts/search?q=criminal%20behavior" title=" criminal behavior"> criminal behavior</a> </p> <a href="https://publications.waset.org/abstracts/86756/cultural-factors-associated-with-male-criminal-behavior-and-inmate-population" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86756.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">174</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Leasing Revisited: Mastering the Digital Transformation with Traditional Financing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tobias%20Huttche">Tobias Huttche</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Canipa-Valdez"> Marco Canipa-Valdez</a>, <a href="https://publications.waset.org/abstracts/search?q=Corinne%20M%C3%BChlebach"> Corinne Mühlebach</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article discusses the role of leasing on the digital transformation process of companies and corresponding economic effects. Based on the traditional mechanisms of leasing, this article focuses in particular on the benefits of leasing as financing instrument with regard to the innovation potential of companies. Practical examples demonstrate how leasing can become an integral part of new business models. Especially, with regard to the digital transformation and corresponding investments in know-how and infrastructure, leasing can play an important role. Furthermore, findings of an empirical survey are presented dealing with the usage of leasing in Switzerland in an international context. The survey shows not only the benefits of leasing against the backdrop of digital transformation but gives guidance on how other countries can benefit from promoting leasing in their legislation and economy. Based on a simulation model for Switzerland, the economic effect of an increase in leasing volume is being calculated. Again, the respective results underline the substantial growth potential. This holds true especially for economies where asset-based lending is rarely used because of a lack of entrepreneurial or private security of the borrower (cash-based financing for developing and emerging countries). Overall, the authors found that leasing using companies are more productive and tend to grow faster than companies using less or none leasing. The positive effects of leasing on emerging digital challenges for companies and entire economies should encourage other countries to facilitate access to leasing as financing instrument by decreasing legal-, tax- and accounting-related requirements in the respective jurisdiction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cash-Based%20financing" title="Cash-Based financing">Cash-Based financing</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20transformation" title=" digital transformation"> digital transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=financing%20instruments" title=" financing instruments"> financing instruments</a>, <a href="https://publications.waset.org/abstracts/search?q=growth" title=" growth"> growth</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation" title=" innovation"> innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=leasing" title=" leasing"> leasing</a> </p> <a href="https://publications.waset.org/abstracts/86940/leasing-revisited-mastering-the-digital-transformation-with-traditional-financing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86940.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">256</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> Effect of Food Supplies Holstein Calves Supplemented with Bacillus Subtilis PB6 in Morbidity and Mortality </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Banca%20Patricia%20Pena%20Revuelta">Banca Patricia Pena Revuelta</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramiro%20Gonzalez%20Avalos"> Ramiro Gonzalez Avalos</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Leonardo%20Rocha%20Valdez"> Juan Leonardo Rocha Valdez</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20%20Gonzalez%20Avalos"> Jose Gonzalez Avalos</a>, <a href="https://publications.waset.org/abstracts/search?q=Karla%20Rodriguez%20Hernandez"> Karla Rodriguez Hernandez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Probiotics are a promising alternative to improve productivity and animals' health. In addition, they can be part of the composition of different types of products, including foods (functional foods), medicines, and dietary supplements. The objective of the present work was to evaluate the effect of the feeding of Holstein calves supplemented with bacillus subtilis PB6 in morbidity and mortality. 60 newborn animals were used, randomly included in 1 of 3 treatments. The treatments were as follows: T1 = control, T2 = 10 g / calf / day. The first takes within 20 min after birth, T3 = 10 g / calf/day. The first takes between 12 and 24 h after birth. In all the treatments, 432 L of pasteurized whole milk divided into two doses/day 07:00 and 15:00, respectively, were given for 60 days. The addition of bacillus subtilis PB6 was carried out in the milk tub at the time of feeding them. The first colostrum intake (2 L • intake) was given within 2 h after birth, after which they were given a second 6 h after the first one. The diseases registered to monitor the morbidity and mortality of the calves were: diarrhea and pneumonia. The registry was carried out from birth to 60 days of life. The parameter evaluated was food consumption. The variable statistical analysis was performed using analysis of variance, and comparison of means was performed using the Tukey test. The value of P < 0.05 was used to consider the statistical difference. The results of the present study in relation to the consumption of food show no statistical difference P < 0.05 between treatments (14,762, 11,698, and 12,403 kg of food average, respectively). Calves group to which they were not provided Bacillus subtilis PB6 obtained higher feed intake. The addition of Bacillus subtilis PB6 in feeding calves does not increase feed intake. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=feeding" title="feeding">feeding</a>, <a href="https://publications.waset.org/abstracts/search?q=development" title=" development"> development</a>, <a href="https://publications.waset.org/abstracts/search?q=milk" title=" milk"> milk</a>, <a href="https://publications.waset.org/abstracts/search?q=probiotic" title=" probiotic "> probiotic </a> </p> <a href="https://publications.waset.org/abstracts/118983/effect-of-food-supplies-holstein-calves-supplemented-with-bacillus-subtilis-pb6-in-morbidity-and-mortality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118983.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">147</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> Microstructure Evolution and Modelling of Shear Forming</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karla%20D.%20Vazquez-Valdez">Karla D.

Wynne</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the last decades manufacturing needs have been changing, leading to the study of manufacturing methods that were underdeveloped, such as incremental forming processes like shear forming. These processes use rotating tools in constant local contact with the workpiece, which is often also rotating, to generate shape. This means much lower loads to forge large parts and no need for expensive special tooling. Potential has already been established by demonstrating manufacture of high-value products, e.g., turbine and satellite parts, with high dimensional accuracy from difficult to manufacture materials. Thus, huge opportunities exist for these processes to replace the current method of manufacture for a range of high value components, e.g., eliminating lengthy machining, reducing material waste and process times; or the manufacture of a complicated shape without the development of expensive tooling. However, little is known about the exact deformation conditions during processing and why certain materials are better than others for shear forming, leading to a lot of trial and error before production. Three alloys were used for this study: Ti-54M, Jethete M154, and IN718. General Microscopy and Electron Backscatter Diffraction (EBSD) were used to measure strains and orientation maps during shear forming. A Design of Experiments (DOE) analysis was also made in order to understand the impact of process parameters in the properties of the final workpieces. Such information was the key to develop a reliable Finite Element Method (FEM) model that closely resembles the deformation paths of this process. Finally, the potential of these three materials to be shear spun was studied using the FEM model and their Forming Limit Diagram (FLD) which led to the development of a rough methodology for testing the shear spinnability of various metals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shear%20forming" title="shear forming">shear forming</a>, <a href="https://publications.waset.org/abstracts/search?q=damage" title=" damage"> damage</a>, <a href="https://publications.waset.org/abstracts/search?q=principal%20strains" title=" principal strains"> principal strains</a>, <a href="https://publications.waset.org/abstracts/search?q=forming%20limit%20diagram" title=" forming limit diagram"> forming limit diagram</a> </p> <a href="https://publications.waset.org/abstracts/101233/microstructure-evolution-and-modelling-of-shear-forming" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101233.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">163</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> Slaughter and Carcass Characterization, and Sensory Qualities of Native, Pure, and Upgraded Breeds of Goat Raised in the Philippines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jonathan%20N.%20Nayga">Jonathan N.

Goats are raised for its meat and regardless of breed the animal is slaughtered for this purpose. In order to document the carcass yield of different goats slaughtered, five (5) different breeds of goats to include Purebred Boer and Anglo-nubian, Crossbred Boer and Anglo-nubian and Philippine Native goat were used in the study. Data on slaughter parameters, carcass characteristics, and sensory evaluation were gathered and analyzed using Complete Random Design (CRD) at 5% level of significance and the results of carcass conformation were assessed descriptively. Results showed that slaughter data such as slaughter/live weight, hot and chilled carcass weights, dressing percentage and percentage drip loss were significantly different (P>0.05) among breeds. On carcass and meat characteristics, pure breed and upgraded Boer were found to be moderately muscular while Native goat was rated as thin muscular. The color of the carcass also revealed that Purebred and crossbred Boer were described dark red, while Native goat was noted to be slightly pale. On sensory evaluation, the results indicated that there was no significant difference (P>0.05) among breeds evaluated. It is therefore concluded that purebred goat has heavier carcass, while both purebred Boer and upgrade are rated slightly muscular. It is further confirms that regardless of breed, goat will have the same sensory characteristics. Thus, it is recommended to slaughter heavier goats to obtain more carcasses with better conformation and quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carcass%20quality" title="carcass quality">carcass quality</a>, <a href="https://publications.waset.org/abstracts/search?q=goat" title=" goat"> goat</a>, <a href="https://publications.waset.org/abstracts/search?q=sensory%20evaluation" title=" sensory evaluation"> sensory evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=slaughter" title=" slaughter"> slaughter</a> </p> <a href="https://publications.waset.org/abstracts/41321/slaughter-and-carcass-characterization-and-sensory-qualities-of-native-pure-and-upgraded-breeds-of-goat-raised-in-the-philippines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41321.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">349</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Use of Recycled Vegetable Oil in the Diet of Lactating Sows</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20Manuel%20Uriarte%20Lopez">Juan Manuel Uriarte Lopez</a>, <a href="https://publications.waset.org/abstracts/search?q=Hector%20Raul%20Guemez%20Gaxiola"> Hector Raul Guemez Gaxiola</a>, <a href="https://publications.waset.org/abstracts/search?q=Javier%20Alonso%20Romo%20Rubio"> Javier Alonso Romo Rubio</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Manuel%20Romo%20Valdez"> Juan Manuel Romo Valdez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this investigation was to determine the influence of the use of recycled vegetable oil from restaurants in the productive performance of sows in lactation. Twenty-four hybrids lactating sows (Landrace x Yorkshire) were divided into three treatments with eight sows per treatment. On day 107 of gestation, the sows were moved to the mesh floor maternity cages in an environment regulated by the environment regulated (2.4 × 0.6 m) contained an area (2.4 × 0.5 m) for newborn pigs on each side, all diets were provided as a dry powder, and the sows received free access to water throughout the experimental period. After farrowing, the sows were fasted for 12 hours, the daily feed ration gradually increased, and the sows had ad libitum access to feed on the fourth day. The diets used were corn-soybean meal-based, containing 0 (CONT), recycled vegetable oil 1.0 % (RVOL), or recycled vegetable oil 1.5 % (RVOH) for 30 days. The diets contained similar calculated levels of crude protein and metabolizable energy and contained vitamins and minerals that exceeded National Research Council (1998) recommendations; sows were fed three times daily. On day 30, piglets were weaned, and performances of lactating sows and nursery piglets were recorded. Results indicated that average daily feed intake (5.58, 5.55, and 5.49 kg for CONT, RVOL, and RVO, respectively) of sows were not affected (P > 0.05) by different dietary. There was no difference in the average body weight of piglets on the day of birth, with 1.33, 1.36, and 1.35 kg, respectively (P > 0.05). There was no difference in average body weight of piglets on day 30, with 6.91, 6.75, and 7.05 kg, respectively 0.05) between treatments numbers of weaned piglets per sow (9.95, 9.80, and 9.80) were not affected by treatments (P > 0.05).In conclusion, the substitution of virgin vegetable oil for recycled vegetable oil in the diet does not affect the productive performance of lactating sows. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lactating" title="lactating">lactating</a>, <a href="https://publications.waset.org/abstracts/search?q=sow" title=" sow"> sow</a>, <a href="https://publications.waset.org/abstracts/search?q=vegetable" title=" vegetable"> vegetable</a>, <a href="https://publications.waset.org/abstracts/search?q=oil" title=" oil"> oil</a> </p> <a href="https://publications.waset.org/abstracts/142975/use-of-recycled-vegetable-oil-in-the-diet-of-lactating-sows" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142975.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">6</span> Practical Experiences in the Development of a Lab-Scale Process for the Production and Recovery of Fucoxanthin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alma%20G%C3%B3mez-Loredo">Alma Gómez-Loredo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Gonz%C3%A1lez-Valdez"> José González-Valdez</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Benavides"> Jorge Benavides</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Rito-Palomares"> Marco Rito-Palomares</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fucoxanthin is a carotenoid that exerts multiple beneficial effects on human health, including antioxidant, anti-cancer, antidiabetic and anti-obesity activity; making the development of a whole process for its production and recovery an important contribution. In this work, the lab-scale production and purification of fucoxanthin in Isocrhysis galbana have been studied. In batch cultures, low light intensities (13.5 μmol/m2s) and bubble agitation were the best conditions for production of the carotenoid with product yields of up to 0.143 mg/g. After fucoxanthin ethanolic extraction from biomass and hexane partition, further recovery and purification of the carotenoid has been accomplished by means of alcohol – salt Aqueous Two-Phase System (ATPS) extraction followed by an ultrafiltration (UF) step. An ATPS comprised of ethanol and potassium phosphate (Volume Ratio (VR) =3; Tie-line Length (TLL) 60% w/w) presented a fucoxanthin recovery yield of 76.24 ± 1.60% among the studied systems and was able to remove 64.89 ± 2.64% of the carotenoid and chlorophyll pollutants. For UF, the addition of ethanol to the original recovered ethanolic ATPS stream to a final relation of 74.15% (w/w) resulted in a reduction of approximately 16% of the protein contents, increasing product purity with a recovery yield of about 63% of the compound in the permeate stream. Considering the production, extraction and primary recovery (ATPS and UF) steps, around a 45% global fucoxanthin recovery should be expected. Although other purification technologies, such as Centrifugal Partition Chromatography are able to obtain fucoxanthin recoveries of up to 83%, the process developed in the present work does not require large volumes of solvents or expensive equipment. Moreover, it has a potential for scale up to commercial scale and represents a cost-effective strategy when compared to traditional separation techniques like chromatography. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aqueous%20two-phase%20systems" title="aqueous two-phase systems">aqueous two-phase systems</a>, <a href="https://publications.waset.org/abstracts/search?q=fucoxanthin" title=" fucoxanthin"> fucoxanthin</a>, <a href="https://publications.waset.org/abstracts/search?q=Isochrysis%20galbana" title=" Isochrysis galbana"> Isochrysis galbana</a>, <a href="https://publications.waset.org/abstracts/search?q=microalgae" title=" microalgae"> microalgae</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrafiltration" title=" ultrafiltration"> ultrafiltration</a> </p> <a href="https://publications.waset.org/abstracts/15256/practical-experiences-in-the-development-of-a-lab-scale-process-for-the-production-and-recovery-of-fucoxanthin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15256.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">424</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> Effect of Gamma Radiation, Age of Paddy, Rice Variety and Packaging Materials on the Surface Free Fatty Acid Content of Brown Rice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zenaida%20M.%20De%20Guzman">Zenaida M.

It is the purpose of the study to determine the effect of gamma radiation, packaging materials and age and variety of paddy on the surface free fatty acid content using two different brown rice variety, namely, RC-160 and SL-7, packed in two different packaging materials, namely, regular polyethylene bag and Super bag irradiated at 0.5 and 1.0 kGy. Brown rice was produced from 2-week old (Lot 1) and two months old paddy (Lot 2) and irradiated at the Co-60 Multipurpose Irradiation Facility, PNRI. The surface Free Fatty Acid (FFA) content was obtained following the AOCS Official Method (1982) with some modifications. The experiment was laid out using Split-Plot Randomized Control Block Design. Analysis of variance (ANOVA) showed that the effects of variety, age of paddy and interactions of both were both significant. The surface FFA of SL-7 variety was found to be significantly higher than the RC-160 variety for all radiation doses. Likewise, Lot 2 was observed to have higher surface FFA than Lot 1 regardless of packaging material and radiation dose. It was observed that the surface FFA of both varieties packed in both packaging materials increased significantly up to the 2nd or 3rd month of storage and remains the same until the 5th month. On the other hand, radiation dose did not significantly affect the surface free fatty acid content for all storage/sampling time while the packaging material significantly interacts with the type of variety and radiation dose. Gamma radiation was proven to have no significant effect on the surface free fatty acid at 0.5 and 1.0 kGy and further analyses are needed to determine the action of gamma radiation to the activity of enzyme (lipase-induced and microbial) responsible for the production of other lipolytic products and the effect of gamma radiation on the integrity of the packaging materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brown%20rice" title="brown rice">brown rice</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20fatty%20acid" title=" free fatty acid"> free fatty acid</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma%20radiation" title=" gamma radiation"> gamma radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=polyethylene%20bag" title=" polyethylene bag "> polyethylene bag </a> </p> <a href="https://publications.waset.org/abstracts/58253/effect-of-gamma-radiation-age-of-paddy-rice-variety-and-packaging-materials-on-the-surface-free-fatty-acid-content-of-brown-rice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58253.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">389</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> Using ICESat-2 Dynamic Ocean Topography to Estimate Western Arctic Freshwater Content</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joshua%20Adan%20Valdez">Joshua Adan Valdez</a>, <a href="https://publications.waset.org/abstracts/search?q=Shawn%20Gallaher"> Shawn Gallaher</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Global climate change has impacted atmospheric temperatures contributing to rising sea levels, decreasing sea ice, and increased freshening of high latitude oceans.

In such control systems, control action is provided by digital controllers with different compensation algorithms, which are designed to meet specific requirements for a given application. Due to the constant search for optimization in industrial processes, it is of interest to design digital controllers that offer ease of realization, improved computational efficiency, affordable return rates, and ease of tuning that ultimately improve the performance of the controlled actuators. There is a vast range of options of compensation algorithms that could be used, although in the industry, most controllers used are based on a PID structure. This research article compares different types of digital compensators implemented in a servo system for DC motor position control. PID compensation is evaluated on its two most common architectures: PID position form (1 DOF), and PID speed form (2 DOF). State feedback algorithms are also evaluated, testing two modern control theory techniques: discrete state observer for non-measurable variables tracking, and a linear quadratic method which allows a compromise between the theoretical optimal control and the realization that most closely matches it. The compared control systems’ performance is evaluated through simulations in the Simulink platform, in which it is attempted to model accurately each of the system’s hardware components. The criteria by which the control systems are compared are reference tracking and disturbance rejection. In this investigation, it is considered that the accurate tracking of the reference signal for a position control system is particularly important because of the frequency and the suddenness in which the control signal could change in position control applications, while disturbance rejection is considered essential because the torque applied to the motor shaft due to sudden load changes can be modeled as a disturbance that must be rejected, ensuring reference tracking. Results show that 2 DOF PID controllers exhibit high performance in terms of the benchmarks mentioned, as long as they are properly tuned. As for controllers based on state feedback, due to the nature and the advantage which state space provides for modelling MIMO, it is expected that such controllers evince ease of tuning for disturbance rejection, assuming that the designer of such controllers is experienced. An in-depth multi-dimensional analysis of preliminary research results indicate that state feedback control method is more satisfactory, but PID control method exhibits easier implementation in most control applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=control" title="control">control</a>, <a href="https://publications.waset.org/abstracts/search?q=DC%20motor" title=" DC motor"> DC motor</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20PID" title=" discrete PID"> discrete PID</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20state%20feedback" title=" discrete state feedback"> discrete state feedback</a> </p> <a href="https://publications.waset.org/abstracts/42513/discrete-pid-and-discrete-state-feedback-control-of-a-brushed-dc-motor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42513.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">1</span> Molecular Docking Analysis of Flavonoids Reveal Potential of Eriodictyol for Breast Cancer Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicole%20C.%20Valdez">Nicole C.

While natural products have been a promising source of chemotherapeutic agents, the challenge remains in finding a bioactive compound that specifically targets cancer cells, minimizing side effects on normal cells. Flavonoids are natural products that act as phytoestrogens and induce the same response as estrogen. They are able to compete with estrogen for binding to ERα; however, it has a higher binding affinity for ERβ. Their abundance in nature and low toxicity make them a potential candidate for breast cancer treatment. This study aimed to determine which particular flavonoids can specifically recognize ERβ and potentially be used for breast cancer treatment through molecular docking. A total of 206 flavonoids comprised of 97 isoflavones and 109 flavanones were collected from ZINC15, while the 3D structures of ERβ and ERα were obtained from Protein Data Bank. These flavonoid subclasses were chosen as they bind more strongly to ERs due to their chemical structure. The structures of the flavonoid ligands were converted using Open Babel, while the estrogen receptor protein structures were prepared using Autodock MGL Tools. The optimal binding site was found using BIOVIA Discovery Studio Visualizer before docking all flavonoids on both ERβ and ERα through Autodock Vina. Genistein is a flavonoid that exhibits anticancer effects by binding to ERβ, so its binding affinity was used as a baseline. Eriodictyol and 4”,6”-Di-O-Galloylprunin both exceeded genistein’s binding affinity for ERβ and was lower than its binding affinity for ERα. Of the two, eriodictyol was pursued due to its antitumor properties on a lung cancer cell line and on glioma cells. It is able to arrest the cell cycle at the G2/M phase by inhibiting the mTOR/PI3k/Akt cascade and is able to induce apoptosis via the PI3K/Akt/NF-kB pathway. Protein pathway and gene analysis were also conducted using ChEMBL and PANTHER and it was shown that eriodictyol might induce anticancer effects through the ROS1, CA7, KMO, and KDM1A genes which are involved in cell proliferation in breast cancer, non-small cell lung cancer, and other diseases. The high binding affinity of eriodictyol to ERβ, as well as its potential affected genes and antitumor effects, therefore, make it a candidate for the development of new breast cancer treatment. Verification through in vitro experiments such as checking the upregulation and downregulation of genes through qPCR and checking cell cycle arrest using a flow cytometry assay is recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=estrogen%20receptor" title=" estrogen receptor"> estrogen receptor</a>, <a href="https://publications.waset.org/abstracts/search?q=flavonoid" title=" flavonoid"> flavonoid</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20docking" title=" molecular docking"> molecular docking</a> </p> <a href="https://publications.waset.org/abstracts/152248/molecular-docking-analysis-of-flavonoids-reveal-potential-of-eriodictyol-for-breast-cancer-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152248.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">89</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">© 2024 World Academy of Science, Engineering and Technology</div> </div> </footer> <a href="javascript:" id="return-to-top"><i class="fas fa-arrow-up"></i></a> <div class="modal" id="modal-template"> <div class="modal-dialog"> <div class="modal-content"> <div class="row m-0 mt-1"> <div class="col-md-12"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> </div> </div> <div class="modal-body"></div> </div> </div> </div> <script src="https://cdn.waset.org/static/plugins/jquery-3.3.1.min.js"></script> <script src="https://cdn.waset.org/static/plugins/bootstrap-4.2.1/js/bootstrap.bundle.min.js"></script> <script src="https://cdn.waset.org/static/js/site.js?v=150220211556"></script> <script> jQuery(document).ready(function() { /*jQuery.get("https://publications.waset.org/xhr/user-menu", function (response) { jQuery('#mainNavMenu').append(response);
