serous ovarian cancer (HGSOC) is characterized by the dissemination of the tumor cells (TC) in the peritoneal cavity forming malignant ascites at the time of diagnosis or recurrence. Still, cytology itself has been underutilized as a modality for the diagnosis of HGSOC from ascites, and histological examination from the tumor tissue is yet the only validated method used. The objective of this study was to evaluate the reliability of cytology in the diagnosis of HGSOC in relation to the histopathological examination. Methods: The study included 42 patients with histologically confirmed HGSOC, accompanied by malignant ascites. To confirm the malignancy of the TC in the ascites and to define their immunophenotype, immunohistochemical reaction (IHC) of the following antigens: Calretinin, MOC, WT1, PAX8, p53, p16 & Ki-67 was evaluated on ascites cytospins and tissue blocks. For complete cytological determination of HGSOC, BRCA 1/2 gene mutation was determined from ascites, tissue block, and blood. BRCA1/2 mutation from blood was performed to define the type of mutation, somatic vs germline. Results: Among 42 patients, the immunophenotype of HGSOC from ascites was confirmed in 36 cases (86%). For more profound analysis, the patients were divided in 3 groups regarding the number of TC present in the ascites: patients with less than 10% TC, 10% TC, and more than 10% TC. From all included patients, in the group with less than 10% TC, there were 10 cases, and only 5 of them(50%) showed HGSOC phenotype; 12 cases had equally 10% of TC, and 11 cases (92%) showed HGSOC phenotype; 20 cases had more than 10% TC and all of them (100%) confirmed the HGSOC immunophenotype from ascites. Only 33 patients were eligible for further BRCA1/2 analysis. Eleven BRCA1/2 mutations were detected from thetissue block: 6 germline and 5 somatic. In 2 cases with less than 10% TC, BRCA1/2 mutation was not detected; 4 cases had 10% TC, and 2 of them (50%) confirmed the mutation; 4 cases had more than 10% TC, and all showed 100% reliability with the tumor tissue. Conclusions: Cytology is a highly reliable method for determining the immunophenotype of HGSOC and BRCA1/2 mutation if more than 10% of tumor cells are present in the ascites. This may present an additional non-invasive clinical approach for fast and effective diagnose in the future, especially in inoperable conditions or relapses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cytology" title="cytology">cytology</a>, <a href="https://publications.waset.org/abstracts/search?q=ascites" title=" ascites"> ascites</a>, <a href="https://publications.waset.org/abstracts/search?q=high-grade%20serous%20ovarian%20cancer" title=" high-grade serous ovarian cancer"> high-grade serous ovarian cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=immunophenotype" title=" immunophenotype"> immunophenotype</a>, <a href="https://publications.waset.org/abstracts/search?q=BRCA1%2F2" title=" BRCA1/2"> BRCA1/2</a> </p> <a href="https://publications.waset.org/abstracts/144274/cytology-is-a-promising-tool-for-the-diagnosis-of-high-grade-serous-ovarian-carcinoma-from-ascites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144274.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">188</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> Teaching Students Collaborative Requirements Engineering: Case Study of Red:Wire</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dagmar%20Monett">Dagmar Monett</a>, <a href="https://publications.waset.org/abstracts/search?q=Sven-Erik%20Kujat"> Sven-Erik Kujat</a>, <a href="https://publications.waset.org/abstracts/search?q=Marvin%20Hartmann"> Marvin Hartmann</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper discusses the use of a template-based approach for documenting high-quality requirements as part of course projects in an undergraduate Software Engineering course.

Therefore the most important question is, which technology shall satisfy the future consumer broadband demands. Currently the consensus is, that the fiber technology has the best technical characteristics to achieve such the high bandwidth rates. But fiber technology is so far very cost-intensive and resource consuming. To avoid these investments, operators are concentrating to upgrade the existing copper and hybrid fiber coax infrastructures. This work presents a comparison of the copper and fiber technologies including an overview about the current German broadband market. Both technologies are reviewed in the terms of demand, willingness to pay and economic efficiency in connection with the technical characteristics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=broadband%20customer%20demand" title="broadband customer demand">broadband customer demand</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber%20development" title=" fiber development"> fiber development</a>, <a href="https://publications.waset.org/abstracts/search?q=g.fast" title=" g.fast"> g.fast</a>, <a href="https://publications.waset.org/abstracts/search?q=vectoring" title=" vectoring"> vectoring</a>, <a href="https://publications.waset.org/abstracts/search?q=willingness%20to%20pay%20for%20broadband%20services" title=" willingness to pay for broadband services"> willingness to pay for broadband services</a> </p> <a href="https://publications.waset.org/abstracts/27608/how-does-improving-the-existing-dsl-infrastructure-influences-the-expansion-of-fiber-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27608.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">469</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">31</span> NMR-Based Metabolomics Reveals Dietary Effects in Liver Extracts of Arctic Charr (Salvelinus alpinus) and Tilapia (Oreochromis mossambicus) Fed Different Levels of Starch</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rani%20Abro">Rani Abro</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ata%20Moazzami"> Ali Ata Moazzami</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Erik%20Lindberg"> Jan Erik Lindberg</a>, <a href="https://publications.waset.org/abstracts/search?q=Torbj%C3%B6rn%20Lundh"> Torbjörn Lundh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effect of dietary starch level on liver metabolism in Arctic charr (Salvelinus alpinus) and tilapia (Oreochromis mossambicus) was studied using 1H-NMR based metabolomics. Fingerlings were fed iso-nitrogenous diets containing 0, 10 and 20 % starch for two months before liver samples were collected for metabolite analysis. Metabolite profiling was performed using 600 MHz NMR Chenomx software. In total, 48 metabolites were profiled in liver extracts from both fish species. Following the profiling, principal component analysis (PCA) and orthogonal partial least square discriminant analysis (OPLC-DA) were performed. These revealed that differences in the concentration of significant metabolites were correlated to the dietary starch level in both species. The most prominent difference in metabolic response to starch feeding between the omnivorous tilapia and the carnivorous Arctic charr was an indication of higher anaerobic metabolism in Arctic charr. The data also indicated that amino acid and pyrimidine metabolism was higher in Artic charr than in tilapia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arctic%20charr" title="arctic charr">arctic charr</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolomics" title=" metabolomics"> metabolomics</a>, <a href="https://publications.waset.org/abstracts/search?q=starch" title=" starch"> starch</a>, <a href="https://publications.waset.org/abstracts/search?q=tilapia" title=" tilapia "> tilapia </a> </p> <a href="https://publications.waset.org/abstracts/24696/nmr-based-metabolomics-reveals-dietary-effects-in-liver-extracts-of-arctic-charr-salvelinus-alpinus-and-tilapia-oreochromis-mossambicus-fed-different-levels-of-starch" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24696.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">457</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">30</span> Evaluation of the Integration of a Direct Reduction Process into an Existing Steel Mill</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nils%20Mueller">Nils Mueller</a>, <a href="https://publications.waset.org/abstracts/search?q=Gregor%20Herz"> Gregor Herz</a>, <a href="https://publications.waset.org/abstracts/search?q=Erik%20Reichelt"> Erik Reichelt</a>, <a href="https://publications.waset.org/abstracts/search?q=Matthias%20Jahn"> Matthias Jahn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the context of climate change, the reduction of greenhouse gas emissions in all economic sectors is considered to be an important factor in order to meet the demands of a sustainable energy system. The steel industry as one of the large industrial CO₂ emitters is currently highly dependent on fossil resources. In order to reduce coke consumption and thereby CO₂ emissions while still being able to further utilize existing blast furnaces, the possibility of including a direct reduction process (DRP) into a fully integrated steel mill was investigated. Therefore, a blast furnace model, derived from literature data and implemented in Aspen Plus, was used to analyze the impact of DRI in the blast furnace process. Furthermore, a state-of-the-art DRP was modeled to investigate the possibility of substituting the reducing agent natural gas with hydrogen. A sensitivity analysis was carried out in order to find the boundary percentage of hydrogen as a reducing agent without penalty to the DRI quality. Lastly, the two modeled process steps were combined to form a route of producing pig iron. By varying boundary conditions of the DRP while recording the CO₂ emissions of the two process steps, the overall potential for the reduction of CO₂ emissions was estimated. Within the simulated range, a maximum reduction of CO₂ emissions of 23.5% relative to typical emissions of a blast furnace could be determined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast%20furnace" title="blast furnace">blast furnace</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20mitigation" title=" CO₂ mitigation"> CO₂ mitigation</a>, <a href="https://publications.waset.org/abstracts/search?q=DRI" title=" DRI"> DRI</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen" title=" hydrogen"> hydrogen</a> </p> <a href="https://publications.waset.org/abstracts/85789/evaluation-of-the-integration-of-a-direct-reduction-process-into-an-existing-steel-mill" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85789.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">284</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">29</span> Combustion Chamber Sizing for Energy Recovery from Furnace Process Gas: Waste to Energy </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Balram%20Panjwani">Balram Panjwani</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernd%20Wittgens"> Bernd Wittgens</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Erik%20Olsen"> Jan Erik Olsen</a>, <a href="https://publications.waset.org/abstracts/search?q=Stein%20Tore%20Johansen"> Stein Tore Johansen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Norwegian ferroalloy industry is a world leader in sustainable production of ferrosilicon, silicon and manganese alloys with the lowest global specific energy consumption. One of the byproducts during the metal reduction process is energy rich off-gas and usually this energy is not harnessed. A novel concept for sustainable energy recovery from ferroalloy off-gas is discussed. The concept is founded on the idea of introducing a combustion chamber in the off-gas section in which energy rich off-gas mainly consisting of CO will be combusted. This will provide an additional degree of freedom for optimizing energy recovery. A well-controlled and high off-gas temperature will assure a significant increase in energy recovery and reduction of emissions to the atmosphere. Design and operation of the combustion chamber depend on many parameters, including the total power capacity of the combustion chamber, sufficient residence time for combusting the complex Poly Aromatic Hydrocarbon (PAH), NOx, as well as converting other potential pollutants. The design criteria for the combustion chamber have been identified and discussed and sizing of the combustion chamber has been carried out considering these design criteria. Computational Fluid Dynamics (CFD) has been utilized extensively for sizing the combustion chamber. The results from our CFD simulations of the flow in the combustion chamber and exploring different off-gas fuel composition are presented. In brief, the paper covers all aspect which impacts the sizing of the combustion chamber, including insulation thickness, choice of insulating material, heat transfer through extended surfaces, multi-staging and secondary air injection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD" title="CFD">CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=combustion%20chamber" title=" combustion chamber"> combustion chamber</a>, <a href="https://publications.waset.org/abstracts/search?q=arc%20furnace" title=" arc furnace"> arc furnace</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20recovery" title=" energy recovery"> energy recovery</a> </p> <a href="https://publications.waset.org/abstracts/33818/combustion-chamber-sizing-for-energy-recovery-from-furnace-process-gas-waste-to-energy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33818.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">319</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">28</span> Atomic Town: History and Vernacular Heritage at the Mary Kathleen Uranium Mine in Australia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erik%20Eklund">Erik Eklund</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mary Kathleen was a purpose-built company town located in northwest Queensland in Australia. It was created to work on a rich uranium deposit discovered in the area in July 1954. The town was complete by 1958, possessing curved streets, modern materials, and a progressive urban planning scheme. Formed in the minds of corporate executives and architects and made manifest in arid zone country between Cloncurry and Mount Isa, Mary Kathleen was a modern marvel in the outback, a town that tamed the wild country of northwest Queensland, or so it seemed. The town was also a product of the Cold War. In the context of a nuclear arms race between the Soviet Union and her allies, and the United States of America (USA) and her Allies, a rapid rush to locate, mine, and process uranium after 1944 led to the creation of uranium towns in Czechoslovakia, Canada, the Soviet Union, USA and Australia of which Mary Kathleen was one such example. Mary Kathleen closed in 1981, and most of the town’s infrastructure was removed. Since then, the town’s ghostly remains have attracted travellers and tourists. Never an officially-sanctioned tourist site, the area has nevertheless become a regular stop for campers and day trippers who have engaged with the site often without formal interpretation.

Our laboratory has pioneered a number of methods for automatically inferring core gene regulatory networks directly from high-throughput data by modeling gene expression (RNA-seq) and chromatin state (ChIP-seq) measurements in terms of genome-wide computational predictions of regulatory sites for hundreds of transcription factors and micro-RNAs. These methods have now been completely automated in an integrated webserver called ISMARA that allows researchers to analyze their own data by simply uploading RNA-seq or ChIP-seq data sets and provides results in an integrated web interface as well as in downloadable flat form. For any data set, ISMARA infers the key regulators in the system, their activities across the input samples, the genes and pathways they target, and the core interactions between the regulators. We believe that by empowering experimental researchers to apply cutting-edge computational systems biology tools to their data in a completely automated manner, ISMARA can play an important role in developing our understanding of regulatory networks across metazoans. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gene%20expression%20analysis" title="gene expression analysis">gene expression analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=high-throughput%20sequencing%20analysis" title=" high-throughput sequencing analysis"> high-throughput sequencing analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=transcription%20factor%20activity" title=" transcription factor activity"> transcription factor activity</a>, <a href="https://publications.waset.org/abstracts/search?q=transcription%20regulation" title=" transcription regulation"> transcription regulation</a> </p> <a href="https://publications.waset.org/abstracts/147333/ismara-completely-automated-inference-of-gene-regulatory-networks-from-high-throughput-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147333.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">65</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">26</span> Prediction of Product Size Distribution of a Vertical Stirred Mill Based on Breakage Kinetics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20R.%20Danielle">C.

These ores have provided new challenges in concentrator design because fine and ultra-fine grinding is required to achieve acceptable recovery rates. Therefore, the correct design of a grinding circuit is important for minimizing unit costs and increasing product quality. The use of ball mills for grinding in fine size ranges is inefficient and, therefore, vertical stirred grinding mills are becoming increasingly popular in the mineral processing industry due to its already known high energy efficiency. This work presents a hypothesis of a methodology to predict the product size distribution of a vertical stirred mill using a Bond ball mill. The Population Balance Model (PBM) was used to empirically analyze the performance of a vertical mill and a Bond ball mill. The breakage parameters obtained for both grinding mills are compared to determine the possibility of predicting the product size distribution of a vertical mill based on the results obtained from the Bond ball mill. The biggest advantage of this methodology is that most of the minerals processing laboratories already have a Bond ball mill to perform the tests suggested in this study. Preliminary results show the possibility of predicting the performance of a laboratory vertical stirred mill using a Bond ball mill. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bond%20ball%20mill" title="bond ball mill">bond ball mill</a>, <a href="https://publications.waset.org/abstracts/search?q=population%20balance%20model" title=" population balance model"> population balance model</a>, <a href="https://publications.waset.org/abstracts/search?q=product%20size%20distribution" title=" product size distribution"> product size distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=vertical%20stirred%20mill" title=" vertical stirred mill"> vertical stirred mill</a> </p> <a href="https://publications.waset.org/abstracts/62771/prediction-of-product-size-distribution-of-a-vertical-stirred-mill-based-on-breakage-kinetics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62771.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">292</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Uncertainties and Resilience: A Study of Pandemic Impact on the Pastoral-Nomadic Communities in India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arati%20S.%20Kade">Arati S.

A review of the literature was performed concerning nomadism and development relations and conflicts by focusing on structural violence on nomadic communities from the caste class and patriarchy as a framework along with the role of the state. Philosophical views on the anti-nomad bias of political theories by Erik Ringmar, along with the decolonial approach by Linda Smith and debrahmanization by Braj Ranjan Mani were used to analyze criminalization of nomads. Data were collected using in-depth telephonic interviews and news reports published during the COVID-19 lockdown in India. Focusing on historical context of current crises, the paper leads to the discussion on how nomadic communities negotiate with the sedentary society during the COVID-19 pandemic. Findings of the current paper approve the hypotheses that the COVID-19 pandemic followed by lockdown deeply impacted the pastoral production system, building on the continued cycle of marginalization by the state and caste society in India, while traditional knowledge stood the test of time. Be it developmental states or pandemics, the nomadic communities have shown their resilience in a number of ways, such as keeping distance from sedentary society, usage of traditional medicine, and relying on traditional leadership. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title="COVID-19">COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=criminalization" title=" criminalization"> criminalization</a>, <a href="https://publications.waset.org/abstracts/search?q=India" title=" India"> India</a>, <a href="https://publications.waset.org/abstracts/search?q=nomadism" title=" nomadism"> nomadism</a>, <a href="https://publications.waset.org/abstracts/search?q=pandemic" title=" pandemic"> pandemic</a>, <a href="https://publications.waset.org/abstracts/search?q=pastoralism" title=" pastoralism"> pastoralism</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience" title=" resilience"> resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20knowledge" title=" traditional knowledge"> traditional knowledge</a> </p> <a href="https://publications.waset.org/abstracts/154983/uncertainties-and-resilience-a-study-of-pandemic-impact-on-the-pastoral-nomadic-communities-in-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154983.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">97</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Different Feedings on Chemical Characteristics of Atlantic Salmon Fillet</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahsa%20Jalili">Mahsa Jalili</a>, <a href="https://publications.waset.org/abstracts/search?q=Trude%20Johansen"> Trude Johansen</a>, <a href="https://publications.waset.org/abstracts/search?q=Signe%20Dille%20Lovmo"> Signe Dille Lovmo</a>, <a href="https://publications.waset.org/abstracts/search?q=Turid%20Rustad"> Turid Rustad</a>, <a href="https://publications.waset.org/abstracts/search?q=Rolf%20Erik%20Olsen"> Rolf Erik Olsen</a>, <a href="https://publications.waset.org/abstracts/search?q=Atle%20M.%20Bones"> Atle M.

The aim of this study was to examine the impact of krill meal, soybean meal, Bactocell® and butyrate fortified feeds and control diet on characteristics of salmon fillet. Thirty Atlantic salmon (6 per each group) were farmed for 12 weeks. All the fish were killed and frozen immediately. The white muscle from top posterior part of dorsal fin was dissected to analyze fat content, carotenoid content, content of water-soluble and salt-soluble proteins, cathepsin B and cathepsin B-L activities. ANOVA test was used to analyze mean and standard error of mean values at 0.05 significance level. There were significant difference in cathepsin B activity, water-soluble proteins and salt-soluble proteins (p-value= 0.005, 0.009 and 0.002). The mean values of other factors were not significantly different among the groups. Cathepsin B activity was higher in soymeal group. Water-soluble proteins were reported higher in soy meal and krill groups and salt-soluble proteins were significantly higher in soy meal and butyrate rich diets. Although soy meal has proven effect on enteritis, it results in higher percentage of protein in fillets. On the other hand, this feeding may have role in textural deterioration of fillets owing to higher values of endogenous cathepsin B in soymeal group. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aquaculture" title="aquaculture">aquaculture</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20quality" title=" food quality"> food quality</a>, <a href="https://publications.waset.org/abstracts/search?q=Krill%20protein%20extract" title=" Krill protein extract"> Krill protein extract</a>, <a href="https://publications.waset.org/abstracts/search?q=prebiotics" title=" prebiotics"> prebiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=probiotics" title=" probiotics"> probiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=Salmo%20salar" title=" Salmo salar"> Salmo salar</a>, <a href="https://publications.waset.org/abstracts/search?q=soy" title=" soy"> soy</a> </p> <a href="https://publications.waset.org/abstracts/79109/different-feedings-on-chemical-characteristics-of-atlantic-salmon-fillet" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79109.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">210</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> Positive Energy Districts in the Swedish Energy System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vartan%20Ahrens%20Kayayan">Vartan Ahrens Kayayan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mattias%20Gustafsson"> Mattias Gustafsson</a>, <a href="https://publications.waset.org/abstracts/search?q=Erik%20Dotzauer"> Erik Dotzauer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The European Union is introducing the positive energy district concept, which has the goal to reduce overall carbon dioxide emissions. Other studies have already mapped the make-up of such districts, and reviewed their definitions and where they are positioned. The Swedish energy system is unique compared to others in Europe, due to the implementation of low-carbon electricity and heat energy sources and high uptake of district heating. The goal for this paper is to start the discussion about how the concept of positive energy districts can best be applied to the Swedish context and meet their mitigation goals. To explore how these differences impact the formation of positive energy districts, two cases were analyzed for their methods and how these integrate into the Swedish energy system: a district in Uppsala with a focus on energy and another in Helsingborg with a focus on climate. The case in Uppsala uses primary energy calculations which can be critisied but take a virtual border that allows for its surrounding system to be considered. The district in Helsingborg has a complex methodology for considering the life cycle emissions of the neighborhood. It is successful in considering the energy balance on a monthly basis, but it can be problematized in terms of creating sub-optimized systems due to setting tight geographical constraints. The discussion of shaping the definitions and methodologies for positive energy districts is taking place in Europe and Sweden. We identify three pitfalls that must be avoided so that positive energy districts meet their mitigation goals in the Swedish context. The goal of pushing out fossil fuels is not relevant in the current energy system, the mismatch between summer electricity production and winter energy demands should be addressed, and further implementations should consider collaboration with the established district heating grid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=positive%20energy%20districts" title="positive energy districts">positive energy districts</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20system" title=" energy system"> energy system</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=European%20Union" title=" European Union"> European Union</a> </p> <a href="https://publications.waset.org/abstracts/169035/positive-energy-districts-in-the-swedish-energy-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169035.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">78</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> Agency Beyond Metaphysics of Subjectivity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erik%20Kuravsky">Erik Kuravsky</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the problems with a post-structuralist account of agency is that it appears to reject the freedom of an acting subject, thus seeming to deny the very phenomenon of agency. However, this is only a problem if we think that human beings can be agents exclusively in terms of being subjects, that is, if we think agency subjectively. Indeed, we tend to understand traditional theories of human freedom (e.g., Plato’s or Kant’s) in terms of a peculiar ability of the subject. The paper suggests to de-subjectivize agency with the help of Heidegger’s later thought. To do it, ir argues that classical theories of agency may indeed be interpreted as subject-oriented (sometimes even by their authors), but do not have to be read as such. Namely, the claim is that what makes agency what it is, what is essential in agency, is not its belonginess to a subject, but its ontological configuration. We may say that agency “happens,” and that there is a very specific ontological characteristics to this happening. The argument of the paper is that we can find these characteristic in the classical accounts of agency and that these characteristics are sufficient to distinguish human freedom from other natural phenomena. In particular, it offers to think agency not as one of human characteristics, but as an ontological event in which human beings take part. Namely, agency is a (non-human) characteristic of the different modes in which the experienceable existence of beings is determined by Being. To be an agent then is to participate in such ontological determination. What enables this participation is the ways human beings non-thematically understand the ontological difference. For example, for Plato, one acts freely only if one is led by an idea of the good, while for Kant the imperative for free action is categorial. The agency of an agent is thus dependent on the differentiation between ideas/categories and beings met in experience – one is “free” from contingent sensibility in terms of what is different from it ontologically. In this light, modern dependence on subjectivity is evident in the fact that the ontological difference is thought as belonging to one’s thinking, consciousness etc. That is, it is taken subjectively. A non-subjective account of agency, on the other hand, requires thinking this difference as belonging to Being itself, and thinking human beings as a medium within which occurs the non-human force of ontological differentiation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Heidegger" title="Heidegger">Heidegger</a>, <a href="https://publications.waset.org/abstracts/search?q=freedom" title=" freedom"> freedom</a>, <a href="https://publications.waset.org/abstracts/search?q=agency" title=" agency"> agency</a>, <a href="https://publications.waset.org/abstracts/search?q=poststructuralism" title=" poststructuralism"> poststructuralism</a> </p> <a href="https://publications.waset.org/abstracts/143750/agency-beyond-metaphysics-of-subjectivity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143750.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">197</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> Case Studies of Educational Technology Integration for Global Citizenship Development among Teacher Candidates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erik%20Jon%20Byker">Erik Jon Byker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Government leaders and education policymakers have increasingly focused on ways that teachers can better prepare children for life in a global society. Such preparation includes the development of global citizenship among young people. Yet, scholars point out that many elementary school educators and teacher candidates have limited awareness of being global citizens in an interdependent world. More and more teacher preparation programs aim to integrate global citizenship in their program plans and use educational technology to help develop global citizenship. Many non-governmental organizations (NGOs), like the Asia Society and Partnership for 21st Century Skills, have led the way in creating global citizenship frameworks that prepare teachers and students with global competencies. The development of global citizenship among teachers needs to begin even before teachers sign their first contract. Global citizenship development should start when teacher candidates are being prepared to teach. Using the Critical Cosmopolitan Theory as a conceptual lens, this paper examines the integration of global citizenship curricula in teacher education programs in North Carolina and Texas in the United States of America. Using a case study methodology, the paper describes and compares the teacher candidates’ (n=136) perceptions of the global citizenship curricula delivered with the aid of educational technology. The study found that after participating in the global citizenship curricula, participants: (1) made conceptual leaps in their global citizenship definitions; (2) developed a stronger commitment for their future role as educators in developing global citizens; and (3) were more willing to take action for social justice-related issues in education. In sum, this paper discusses empirical findings related to the ways to integrate educational technology in preparing globally competent teachers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=educational%20technology" title="educational technology">educational technology</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20education" title=" global education"> global education</a>, <a href="https://publications.waset.org/abstracts/search?q=intercultural%20awareness" title=" intercultural awareness"> intercultural awareness</a>, <a href="https://publications.waset.org/abstracts/search?q=teacher%20candidates" title=" teacher candidates"> teacher candidates</a> </p> <a href="https://publications.waset.org/abstracts/130287/case-studies-of-educational-technology-integration-for-global-citizenship-development-among-teacher-candidates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130287.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">208</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">20</span> Cognitive Dysfunctioning and the Fronto-Limbic Network in Bipolar Disorder Patients: A Fmri Meta-Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rahele%20Mesbah">Rahele Mesbah</a>, <a href="https://publications.waset.org/abstracts/search?q=Nic%20Van%20Der%20Wee"> Nic Van Der Wee</a>, <a href="https://publications.waset.org/abstracts/search?q=Manja%20Koenders"> Manja Koenders</a>, <a href="https://publications.waset.org/abstracts/search?q=Erik%20Giltay"> Erik Giltay</a>, <a href="https://publications.waset.org/abstracts/search?q=Albert%20Van%20Hemert"> Albert Van Hemert</a>, <a href="https://publications.waset.org/abstracts/search?q=Max%20De%20Leeuw"> Max De Leeuw</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Patients with bipolar disorder (BD), characterized by depressive and manic episodes, often suffer from cognitive dysfunction. An up-to-date meta-analysis of functional Magnetic Resonance Imaging (fMRI) studies examining cognitive function in BD is lacking. Objective: The aim of the current fMRI meta-analysis is to investigate brain functioning of bipolar patients compared with healthy subjects within three domains of emotion processing, reward processing, and working memory. Method: Differences in brain regions activation were tested within whole-brain analysis using the activation likelihood estimation (ALE) method. Separate analyses were performed for each cognitive domain. Results: A total of 50 fMRI studies were included: 20 studies used an emotion processing (316 BD and 369 HC) task, 9 studies a reward processing task (215 BD and 213 HC), and 21 studies used a working memory task (503 BD and 445 HC). During emotion processing, BD patients hyperactivated parts of the left amygdala and hippocampus as compared to HC’s, but showed hypoactivation in the inferior frontal gyrus (IFG). Regarding reward processing, BD patients showed hyperactivation in part of the orbitofrontal cortex (OFC). During working memory, BD patients showed increased activity in the prefrontal cortex (PFC) and anterior cingulate cortex (ACC). Conclusions: This meta-analysis revealed evidence for activity disturbances in several brain areas involved in the cognitive functioning of BD patients. Furthermore, most of the found regions are part of the so-called fronto-limbic network which is hypothesized to be affected as a result of BD candidate genes' expression. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cognitive%20functioning" title="cognitive functioning">cognitive functioning</a>, <a href="https://publications.waset.org/abstracts/search?q=fMRI%20analysis" title=" fMRI analysis"> fMRI analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=bipolar%20disorder" title=" bipolar disorder"> bipolar disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=fronto-limbic%20network" title=" fronto-limbic network"> fronto-limbic network</a> </p> <a href="https://publications.waset.org/abstracts/136510/cognitive-dysfunctioning-and-the-fronto-limbic-network-in-bipolar-disorder-patients-a-fmri-meta-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136510.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">462</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> Social Freedom and Real Utopias: Making ‘Eroding Capitalism’ a Theme in Axel Honneth’s Theory of Socialism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yotaro%20Natani">Yotaro Natani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In his recent works, Frankfurt School theorist Axel Honneth elucidates an intersubjective notion of social freedom and outlines a vision of socialism as the realization of social freedom in the family, market economy, and public sphere. These arguments are part of his broader project of defending the tradition of immanent critique and normative reconstruction. In contrast, American Marxist sociologist Erik Olin Wright spells out a vision of socialism in terms of building real utopias -democratic, egalitarian, alternative institutions- through the exercise of civil society’s social power over the economy and state. Wright identifies ‘eroding capitalism’ as the framework for thinking about the strategic logics of gradually diminishing the dominance of capitalism. Both thinkers envision the transition toward socialism in terms of democratic experimentation; Honneth is more attentive to the immanent norms of social life, whereas Wright is better aware of the power of antagonistic structures. This paper attempts to synthesize the ideas of Honneth and Wright. It will show that Honneth’s critique of capitalism suffers from certain ambiguities because he attributes normative legitimacy to existing institutions, resulting in arguments that do not problematize aspects of capitalist structures. This paper will argue that incorporating the notion of power and thematizing the erosion of capitalism as a long-term goal for socialist change will allow Honneth to think more precisely about the conditions for realizing social freedom, in a manner that is still consistent with the immanent critique tradition. Such reformulation will result in a concept of social freedom that is less static and rooted in functional teleology and more oriented toward creative agency and experimental democracy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Axel%20Honneth" title="Axel Honneth">Axel Honneth</a>, <a href="https://publications.waset.org/abstracts/search?q=immanent%20critique" title=" immanent critique"> immanent critique</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20utopias" title=" real utopias"> real utopias</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20freedom" title=" social freedom"> social freedom</a>, <a href="https://publications.waset.org/abstracts/search?q=socialism" title=" socialism"> socialism</a> </p> <a href="https://publications.waset.org/abstracts/114840/social-freedom-and-real-utopias-making-eroding-capitalism-a-theme-in-axel-honneths-theory-of-socialism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114840.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">145</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">18</span> Calculating Asphaltenes Precipitation Onset Pressure by Using Cardanol as Precipitation Inhibitor: A Strategy to Increment the Oil Well Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Camilo%20A.%20Guerrero-Martin">Camilo A.

It fouls piping and surface installations, as well as cause serious flow assurance complications and decline oil well production. Therefore, researchers have shown an interest in chemical treatments to control this phenomenon. The aim of this paper is to assess the asphaltenes precipitation onset of crude oils in the presence of cardanol, by titrating the crude with n-heptane. Moreover, based on this results obtained at atmosphere pressure, the asphaltenes precipitation onset pressure were calculated to predict asphaltenes precipitation in the reservoir, by using differential liberation and refractive index data of the oils. The influence of cardanol concentrations in the asphaltenes stabilization of three Brazilian crude oils samples (with similar API densities) was studied. Therefore, four formulations of cardanol in toluene were prepared: 0, 3, 5, 10 and 15 m/m%. The formulations were added to the crude at 2:98 ratio. The petroleum samples were characterized by API density, elemental analysis and differential liberation test. The asphaltenes precipitation onset (APO) was determined by titrating with n-heptane and monitoring with near-infrared (NIR). UV-Vis spectroscopy experiments were also done to assess the precipitate asphaltenes content. The asphaltenes precipitation envelopes (APE) were also determined by numerical simulation (Multiflash). In addition, the adequate artificial lift systems (ALS) for the oils were selected. It was based on the downhole well profile and a screening methodology. Finally, the oil flowrates were modelling by NODAL analysis production system in the PIPESIM software. The results of this study show that the asphaltenes precipitation onset of the crude oils were 2.2, 2.3 and 6.0 mL of n-heptane/g of oil. The cardanol was an effective inhibitor of asphaltenes precipitation for the crude oils used in this study, since it displaces the precipitation pressure of the oil to lower values. This indicates that cardanol can increase the oil wells productivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asphaltenes" title="asphaltenes">asphaltenes</a>, <a href="https://publications.waset.org/abstracts/search?q=NODAL%20analysis%20production%20system" title=" NODAL analysis production system"> NODAL analysis production system</a>, <a href="https://publications.waset.org/abstracts/search?q=precipitation%20pressure%20onset" title=" precipitation pressure onset"> precipitation pressure onset</a>, <a href="https://publications.waset.org/abstracts/search?q=inhibitory%20molecule" title=" inhibitory molecule"> inhibitory molecule</a> </p> <a href="https://publications.waset.org/abstracts/83321/calculating-asphaltenes-precipitation-onset-pressure-by-using-cardanol-as-precipitation-inhibitor-a-strategy-to-increment-the-oil-well-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83321.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">176</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> Screening of Wheat Wild Relatives as a Gene Pool for Improved Photosynthesis in Wheat Breeding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amanda%20J.%20Burridge">Amanda J.

However, past selection for domestication traits has reduced the genetic variation in modern wheat cultivars, a fact that could severely limit the future rate of genetic gain. The genetic variation in agronomically important traits for the wild relatives and progenitors of wheat is far greater than that of the current domesticated cultivars, but transferring these traits into modern cultivars is not straightforward. Between the elite cultivars of wheat, photosynthetic capacity is a key trait for which there is limited variation. Early screening of wheat wild relative and progenitors has shown differences in photosynthetic capacity and efficiency not only between wild relative species but marked differences between the accessions of each species. By identifying wild relative accessions with improved photosynthetic traits and characterising the genetic variation responsible, it is possible to incorporate these traits into advanced breeding programmes by wide crossing and introgression programmes. To identify the potential variety of photosynthetic capacity and efficiency available in the secondary and tertiary genepool, a wide scale survey was carried out for over 600 accessions from 80 species including those from the genus Aegilops, Triticum, Thinopyrum, Elymus, and Secale. Genotype data were generated for each accession using a ‘Wheat Wild Relative’ Single Nucleotide Polymorphism (SNP) genotyping array composed of 35,000 SNP markers polymorphic between wild relatives and elite hexaploid wheat. This genotype data was combined with phenotypic measurements such as gas exchange (CO₂, H₂O), chlorophyll fluorescence, growth, morphology, and RuBisCO activity to identify potential breeding material with enhanced photosynthetic capacity and efficiency. The data and associated analysis tools presented here will prove useful to anyone interested in increasing the genetic diversity in hexaploid wheat or the application of complex genotyping data to plant breeding. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wheat" title="wheat">wheat</a>, <a href="https://publications.waset.org/abstracts/search?q=wild%20relatives" title=" wild relatives"> wild relatives</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-breeding" title=" pre-breeding"> pre-breeding</a>, <a href="https://publications.waset.org/abstracts/search?q=genomics" title=" genomics"> genomics</a>, <a href="https://publications.waset.org/abstracts/search?q=photosynthesis" title=" photosynthesis"> photosynthesis</a> </p> <a href="https://publications.waset.org/abstracts/93210/screening-of-wheat-wild-relatives-as-a-gene-pool-for-improved-photosynthesis-in-wheat-breeding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93210.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">224</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> Cleaning of Polycyclic Aromatic Hydrocarbons (PAH) Obtained from Ferroalloys Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stefan%20Andersson">Stefan Andersson</a>, <a href="https://publications.waset.org/abstracts/search?q=Balram%20Panjwani"> Balram Panjwani</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernd%20Wittgens"> Bernd Wittgens</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Erik%20Olsen"> Jan Erik Olsen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Polycyclic Aromatic hydrocarbons are organic compounds consisting of only hydrogen and carbon aromatic rings. PAH are neutral, non-polar molecules that are produced due to incomplete combustion of organic matter. These compounds are carcinogenic and interact with biological nucleophiles to inhibit the normal metabolic functions of the cells. Norways, the most important sources of PAH pollution is considered to be aluminum plants, the metallurgical industry, offshore oil activity, transport, and wood burning. Stricter governmental regulations regarding emissions to the outer and internal environment combined with increased awareness of the potential health effects have motivated Norwegian metal industries to increase their efforts to reduce emissions considerably. One of the objective of the ongoing industry and Norwegian research council supported "SCORE" project is to reduce potential PAH emissions from an off gas stream of a ferroalloy furnace through controlled combustion. In a dedicated combustion chamber. The sizing and configuration of the combustion chamber depends on the combined properties of the bulk gas stream and the properties of the PAH itself. In order to achieve efficient and complete combustion the residence time and minimum temperature need to be optimized. For this design approach reliable kinetic data of the individual PAH-species and/or groups thereof are necessary. However, kinetic data on the combustion of PAH are difficult to obtain and there is only a limited number of studies. The paper presents an evaluation of the kinetic data for some of the PAH obtained from literature. In the present study, the oxidation is modelled for pure PAH and also for PAH mixed with process gas. Using a perfectly stirred reactor modelling approach the oxidation is modelled including advanced reaction kinetics to study influence of residence time and temperature on the conversion of PAH to CO2 and water. A Chemical Reactor Network (CRN) approach is developed to understand the oxidation of PAH inside the combustion chamber. Chemical reactor network modeling has been found to be a valuable tool in the evaluation of oxidation behavior of PAH under various conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PAH" title="PAH">PAH</a>, <a href="https://publications.waset.org/abstracts/search?q=PSR" title=" PSR"> PSR</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20recovery" title=" energy recovery"> energy recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=ferro%20alloy%20furnace" title=" ferro alloy furnace "> ferro alloy furnace </a> </p> <a href="https://publications.waset.org/abstracts/30355/cleaning-of-polycyclic-aromatic-hydrocarbons-pah-obtained-from-ferroalloys-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30355.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">273</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> Investigation of Dry-Blanching and Freezing Methods of Fruits</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Epameinondas%20Xanthakis">Epameinondas Xanthakis</a>, <a href="https://publications.waset.org/abstracts/search?q=Erik%20Kaunisto"> Erik Kaunisto</a>, <a href="https://publications.waset.org/abstracts/search?q=Alain%20Le-Bail"> Alain Le-Bail</a>, <a href="https://publications.waset.org/abstracts/search?q=Lilia%20Ahrn%C3%A9"> Lilia Ahrné</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fruits and vegetables are characterized as perishable food matrices due to their short shelf life as several deterioration mechanisms are being involved. Prior to the common preservation methods like freezing or canning, fruits and vegetables are being blanched in order to inactivate deteriorative enzymes. Both conventional blanching pretreatments and conventional freezing methods hide drawbacks behind their beneficial impacts on the preservation of those matrices. Conventional blanching methods may require longer processing times, leaching of minerals and nutrients due to the contact with the warm water which in turn leads to effluent production with large BOD. An important issue of freezing technologies is the size of the formed ice crystals which is also critical for the final quality of the frozen food as it can cause irreversible damage to the cellular structure and subsequently to degrade the texture and the colour of the product. Herein, the developed microwave blanching methodology and the results regarding quality aspects and enzyme inactivation will be presented. Moreover, heat transfer phenomena, mass balance, temperature distribution, and enzyme inactivation (such as Pectin Methyl Esterase and Ascorbic Acid Oxidase) of our microwave blanching approach will be evaluated based on measurements and computer modelling. The present work is part of the COLDμWAVE project which aims to the development of an innovative environmentally sustainable process for blanching and freezing of fruits and vegetables with improved textural and nutritional quality. In this context, COLDµWAVE will develop tailored equipment for MW blanching of vegetables that has very high energy efficiency and no water consumption. Furthermore, the next steps of this project regarding the development of innovative pathways in MW assisted freezing to improve the quality of frozen vegetables, by exploring in depth previous results acquired by the authors, will be presented. The application of MW assisted freezing process on fruits and vegetables it is expected to lead to improved quality characteristics compared to the conventional freezing.

Currently, these parameters require human inspection, a multitude of instruments employing a variety of sensor technologies, and predictive model types or destructive and slow chemical analysis. This paper investigates the feasibility of applying near-infrared hyperspectral imaging (NIR-HSI) to grain quality analysis. For this study two datasets of NIR hyperspectral images in the wavelength range of 900 nm - 1700 nm have been used. Both datasets contain images of sparsely and densely packed grain kernels. The first dataset contains ~87,000 image crops of bulk wheat samples from 63 harvests where protein value has been determined by the FOSS Infratec NOVA which is the golden industry standard for protein content estimation in bulk samples of cereal grain. The second dataset consists of ~28,000 image crops of bulk grain kernels from seven different wheat varieties and a single rye variety. In the first dataset, protein regression analysis is the problem to solve while variety classification analysis is the problem to solve in the second dataset. Deep convolutional neural networks (CNNs) have the potential to utilize spatio-spectral correlations within a hyperspectral image to simultaneously estimate the qualitative and quantitative parameters. CNNs can autonomously derive meaningful representations of the input data reducing the need for advanced preprocessing techniques required for classical chemometric model types such as artificial neural networks (ANNs) and partial least-squares regression (PLS-R). A comparison between different CNN architectures utilizing 2D and 3D convolution is conducted. These results are compared to the performance of ANNs and PLS-R. Additionally, a variety of preprocessing techniques from image analysis and chemometrics are tested. These include centering, scaling, standard normal variate (SNV), Savitzky-Golay (SG) filtering, and detrending. The results indicate that the combination of NIR-HSI and CNNs has the potential to be the foundation for an automatic system unifying qualitative and quantitative grain quality analysis within a single sensor technology and predictive model type. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title="deep learning">deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=grain%20analysis" title=" grain analysis"> grain analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperspectral%20imaging" title=" hyperspectral imaging"> hyperspectral imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=preprocessing%20techniques" title=" preprocessing techniques"> preprocessing techniques</a> </p> <a href="https://publications.waset.org/abstracts/157339/deep-learning-for-qualitative-and-quantitative-grain-quality-analysis-using-hyperspectral-imaging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157339.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">99</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> Li2S Nanoparticles Impact on the First Charge of Li-ion/Sulfur Batteries: An Operando XAS/XES Coupled With XRD Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alice%20Robba">Alice Robba</a>, <a href="https://publications.waset.org/abstracts/search?q=Renaud%20Bouchet"> Renaud Bouchet</a>, <a href="https://publications.waset.org/abstracts/search?q=Celine%20Barchasz"> Celine Barchasz</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Francois%20Colin"> Jean-Francois Colin</a>, <a href="https://publications.waset.org/abstracts/search?q=Erik%20Elkaim"> Erik Elkaim</a>, <a href="https://publications.waset.org/abstracts/search?q=Kristina%20Kvashnina"> Kristina Kvashnina</a>, <a href="https://publications.waset.org/abstracts/search?q=Gavin%20Vaughan"> Gavin Vaughan</a>, <a href="https://publications.waset.org/abstracts/search?q=Matjaz%20Kavcic"> Matjaz Kavcic</a>, <a href="https://publications.waset.org/abstracts/search?q=Fannie%20Alloin"> Fannie Alloin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With their high theoretical energy density (~2600 Wh.kg-1), lithium/sulfur (Li/S) batteries are highly promising, but these systems are still poorly understood due to the complex mechanisms/equilibria involved. Replacing S8 by Li2S as the active material allows the use of safer negative electrodes, like silicon, instead of lithium metal. S8 and Li2S have different conductivity and solubility properties, resulting in a profoundly changed activation process during the first cycle. Particularly, during the first charge a high polarization and a lack of reproducibility between tests are observed. Differences observed between raw Li2S material (micron-sized) and that electrochemically produced in a battery (nano-sized) may indicate that the electrochemical process depends on the particle size. Then the major focus of the presented work is to deepen the understanding of the Li2S material charge mechanism, and more precisely to characterize the effect of the initial Li2S particle size both on the mechanism and the electrode preparation process. To do so, Li2S nanoparticles were synthetized according to two ways: a liquid path synthesis and a dissolution in ethanol, allowing Li2S nanoparticles/carbon composites to be made. Preliminary chemical and electrochemical tests show that starting with Li2S nanoparticles could effectively suppress the high initial polarization but also influence the electrode slurry preparation. Indeed, it has been shown that classical formulation process - a slurry composed of Polyvinylidone Fluoride polymer dissolved in N-methyle-2-pyrrolidone - cannot be used with Li2S nanoparticles. This reveals a complete different Li2S material behavior regarding polymers and organic solvents when going at the nanometric scale. Then the coupling between two operando characterizations such as X-Ray Diffraction (XRD) and X-Ray Absorption and Emission Spectroscopy (XAS/XES) have been carried out in order to interpret the poorly understood first charge. This study discloses that initial particle size of the active material has a great impact on the working mechanism and particularly on the different equilibria involved during the first charge of the Li2S based Li-ion batteries. These results explain the electrochemical differences and particularly the polarization differences observed during the first charge between micrometric and nanometric Li2S-based electrodes. Finally, this work could lead to a better active material design and so to more efficient Li2S-based batteries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Li-ion%2FSulfur%20batteries" title="Li-ion/Sulfur batteries">Li-ion/Sulfur batteries</a>, <a href="https://publications.waset.org/abstracts/search?q=Li2S%20nanoparticles%20effect" title=" Li2S nanoparticles effect"> Li2S nanoparticles effect</a>, <a href="https://publications.waset.org/abstracts/search?q=Operando%20characterizations" title=" Operando characterizations"> Operando characterizations</a>, <a href="https://publications.waset.org/abstracts/search?q=working%20mechanism" title=" working mechanism"> working mechanism</a> </p> <a href="https://publications.waset.org/abstracts/57906/li2s-nanoparticles-impact-on-the-first-charge-of-li-ionsulfur-batteries-an-operando-xasxes-coupled-with-xrd-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57906.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">12</span> Topographic Coast Monitoring Using UAV Photogrammetry: A Case Study in Port of Veracruz Expansion Project</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Lia%C3%B1o-Carrera">Francisco Liaño-Carrera</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Enrique%20Ba%C3%B1os-Illana"> Jorge Enrique Baños-Illana</a>, <a href="https://publications.waset.org/abstracts/search?q=Arturo%20G%C3%B3mez-Barrero"> Arturo Gómez-Barrero</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Isaac%20Ram%C3%ADrez-Mac%C3%ADas"> José Isaac Ramírez-Macías</a>, <a href="https://publications.waset.org/abstracts/search?q=Erik%20Omar%20Paredes-Ju%C3%A1Rez"> Erik Omar Paredes-JuáRez</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Salas-Monreal"> David Salas-Monreal</a>, <a href="https://publications.waset.org/abstracts/search?q=Mayra%20Lorena%20Riveron-Enzastiga"> Mayra Lorena Riveron-Enzastiga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Topographical changes in coastal areas are usually assessed with airborne LIDAR and conventional photogrammetry. In recent times Unmanned Aerial Vehicles (UAV) have been used several in photogrammetric applications including coastline evolution. However, its use goes further by using the points cloud associated to generate beach Digital Elevation Models (DEM). We present a methodology for monitoring coastal topographic changes along a 50 km coastline in Veracruz, Mexico using high-resolution images (less than 10 cm ground resolution) and dense points cloud captured with an UAV. This monitoring develops in the context of the port of Veracruz expansion project which construction began in 2015 and intends to characterize coast evolution and prevent and mitigate project impacts on coastal environments. The monitoring began with a historical coastline reconstruction since 1979 to 2015 using aerial photography and Landsat imagery. We could define some patterns: the northern part of the study area showed accretion while the southern part of the study area showed erosion. Since the study area is located off the port of Veracruz, a touristic and economical Mexican urban city, where coastal development structures have been built since 1979 in a continuous way, the local beaches of the touristic area are been refilled constantly. Those areas were not described as accretion since every month sand-filled trucks refill the sand beaches located in front of the hotel area. The construction of marinas and the comitial port of Veracruz, the old and the new expansion were made in the erosion part of the area. Northward from the City of Veracruz the beaches were described as accretion areas while southward from the city, the beaches were described as erosion areas. One of the problems is the expansion of the new development in the southern area of the city using the beach view as an incentive to buy front beach houses. We assessed coastal changes between seasons using high-resolution images and also points clouds during 2016 and preliminary results confirm that UAVs can be used in permanent coast monitoring programs with excellent performance and detail. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20elevation%20model" title="digital elevation model">digital elevation model</a>, <a href="https://publications.waset.org/abstracts/search?q=high-resolution%20images" title=" high-resolution images"> high-resolution images</a>, <a href="https://publications.waset.org/abstracts/search?q=topographic%20coast%20monitoring" title=" topographic coast monitoring"> topographic coast monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=unmanned%20aerial%20vehicle" title=" unmanned aerial vehicle"> unmanned aerial vehicle</a> </p> <a href="https://publications.waset.org/abstracts/56681/topographic-coast-monitoring-using-uav-photogrammetry-a-case-study-in-port-of-veracruz-expansion-project" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56681.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">270</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> Changes in Heavy Metals Bioavailability in Manure-Derived Digestates and Subsequent Hydrochars to Be Used as Soil Amendments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hellen%20L.%20De%20Castro%20e%20Silva">Hellen L.

However, due to the non-digestibility of these elements and reduced dry matter during the anaerobic digestion process, metal concentrations are higher in digestates than in feedstocks, which might hamper their use as fertilisers according to the threshold values of some country policies. Furthermore, there is uncertainty regarding the required assimilated amount of these elements by some crops, which might result in their bioaccumulation. Therefore, further processing of the digestate to obtain safe fertilizing products has been recommended. This research aims to analyze the effect of applying the hydrothermal carbonization process to manure-derived digestates as a thermal treatment to reduce the bioavailability of heavy metals in mono and co-digestates derived from pig manure and maize from contaminated land in France. This study examined pig manure collected from a novel stable system (VeDoWs, province of East Flanders, Belgium) that separates the collection of pig urine and feces, resulting in a solid fraction of manure with high up-concentration of heavy metals and nutrients. Mono-digestion and co-digestion processes were conducted in semi-continuous reactors for 45 days at mesophilic conditions, in which the digestates were dried at 105 °C for 24 hours. Then, hydrothermal carbonization was applied to a 1:10 solid/water ratio to guarantee controlled experimental conditions in different temperatures (180, 200, and 220 °C) and residence times (2 h and 4 h). During the process, the pressure was generated autogenously, and the reactor was cooled down after completing the treatments. The solid and liquid phases were separated through vacuum filtration, in which the solid phase of each treatment -hydrochar- was dried and ground for chemical characterization. Different fractions (exchangeable / adsorbed fraction - F1, carbonates-bound fraction - F2, organic matter-bound fraction - F3, and residual fraction – F4) of some heavy metals (Cd, Cr, Ni, and Cr) have been determined in digestates and derived hydrochars using the modified Community Bureau of Reference (BCR) sequential extraction procedure. The main results indicated a difference in the heavy metals fractionation between digestates and their derived hydrochars; however, the hydrothermal carbonization operating conditions didn’t have remarkable effects on heavy metals partitioning between the hydrochars of the proposed treatments. Based on the estimated potential ecological risk assessment, there was one level decrease (considerate to moderate) when comparing the HMs partitioning in digestates and derived hydrochars. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title="heavy metals">heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=bioavailability" title=" bioavailability"> bioavailability</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrothermal%20treatment" title=" hydrothermal treatment"> hydrothermal treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-based%20fertilisers" title=" bio-based fertilisers"> bio-based fertilisers</a>, <a href="https://publications.waset.org/abstracts/search?q=agriculture" title=" agriculture"> agriculture</a> </p> <a href="https://publications.waset.org/abstracts/157604/changes-in-heavy-metals-bioavailability-in-manure-derived-digestates-and-subsequent-hydrochars-to-be-used-as-soil-amendments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157604.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">100</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> Insertion of Photovoltaic Energy at Residential Level at Tegucigalpa and Comayagüela, Honduras</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tannia%20Vindel">Tannia Vindel</a>, <a href="https://publications.waset.org/abstracts/search?q=Angel%20Matute"> Angel Matute</a>, <a href="https://publications.waset.org/abstracts/search?q=Erik%20Elvir"> Erik Elvir</a>, <a href="https://publications.waset.org/abstracts/search?q=Kelvin%20Santos"> Kelvin Santos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Currently in Honduras, is been incentivized the generation of energy using renewable fonts, such as: hydroelectricity, wind power, biomass and, more recently with the strongest growth, photovoltaic energy. In July 2015 were installed 455.2 MW of photovoltaic energy, increasing by 24% the installed capacity of the national interconnected system existing in 2014, according the National Energy Company (NEC), that made possible reduce the thermoelectric dependency of the system. Given the good results of those large-scale photovoltaic plants, arises the question: is it interesting for the distribution utility and for the consumers the integration of photovoltaic systems in micro-scale in the urban and rural areas? To answer that question has been researched the insertion of photovoltaic energy in the residential sector in Tegucigalpa and Comayagüela (Central District), Honduras to determine the technical and economic viability. Francisco Morazán department, according the National Statistics Institute (NSI), in 2001 had more than 180,000 houses with power service. Tegucigalpa, department and Honduras capital, and Comayagüela, both, have the highest population density in the region, with 1,300,000 habitants in 2014 (NSI). The residential sector in the south-central region of Honduras represents a high percentage being 49% of total consumption, according with NEC in 2014; where 90% of this sector consumes in a range of 0 to 300 kWh / month. All this, in addition to the high level of losses in the transmission and distribution systems, 31.3% in 2014, and the availability of an annual average solar radiation of 5.20 kWh/(m2∙day) according to the NASA, suggests the feasibility of the implementation of photovoltaic systems as a solution to give a level of independency to the households, and besides could be capable of injecting the non-used energy to the grid. The capability of exchange of energy with the grid could make the photovoltaic systems acquisition more affordable to the consumers, because of the compensation energy programs or other kinds of incentives that could be created. Technical viability of the photovoltaic systems insertion has been analyzed, considering the solar radiation monthly average to determine the monthly average of energy that would be generated with the technology accessible locally and the effects of the injection of the energy locally generated on the grid. In addition, the economic viability has been analyzed too, considering the photovoltaic systems high costs, costs of the utility, location and monthly energy consumption requirements of the families. It was found that the inclusion of photovoltaic systems in Tegucigalpa and Comayagüela could decrease in 6 MW the demand for the region if 100% of the households use photovoltaic systems, which acquisition may be more accessible with the help of government incentives and/or the application of energy exchange programs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=grid%20connected" title="grid connected">grid connected</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic" title=" photovoltaic"> photovoltaic</a>, <a href="https://publications.waset.org/abstracts/search?q=residential" title=" residential"> residential</a>, <a href="https://publications.waset.org/abstracts/search?q=technical%20analysis" title=" technical analysis"> technical analysis</a> </p> <a href="https://publications.waset.org/abstracts/42517/insertion-of-photovoltaic-energy-at-residential-level-at-tegucigalpa-and-comayaguela-honduras" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42517.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">263</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> Transcriptomic and Translational Regulation of Peroxisome Proliferator-Activated Receptors after Different Feedings in Salmon</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahsa%20Jalili">Mahsa Jalili</a>, <a href="https://publications.waset.org/abstracts/search?q=Essa%20Ehsan%20Khan"> Essa Ehsan Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Signe%20Dille%20Lovmo"> Signe Dille Lovmo</a>, <a href="https://publications.waset.org/abstracts/search?q=Augustine%20Akruwe"> Augustine Akruwe</a>, <a href="https://publications.waset.org/abstracts/search?q=Egil%20Lien"> Egil Lien</a>, <a href="https://publications.waset.org/abstracts/search?q=Rolf%20Erik%20Olsen"> Rolf Erik Olsen</a>, <a href="https://publications.waset.org/abstracts/search?q=Trygve%20Sigholt"> Trygve Sigholt</a>, <a href="https://publications.waset.org/abstracts/search?q=Atle%20Magnus%20Bones"> Atle Magnus Bones</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Data from the Norwegian Directorate of Fisheries reported that >1.2 million tons of Atlantic salmon were produced in Norway aquaculture industry in 2016. Peroxisome proliferator-activated receptors (PPARs) are one of the key transcription factor families that respond to nutritional ligands. Recent studies have shown the connection between PPARs with lipid and carbohydrate metabolism in aquaculture. To our knowledge, there is no published data about the effects of krill meal, soybean meal, Bactocell ® and butyrate feedings compared to control group on PPARs gene and protein expressions in Atlantic salmon. Fish, 1year +postsmolt, average weight 250 gram were cultured for 12 weeks after acclimatization by control commercial feeding in 2 weeks after hatchery. Water oxygen rate, salinity, and temperature were monitored every second day. At the end of the trial, fish were taken from tanks randomly, and four replicates per group were collected and stored in -80 freezers until analysis. Total RNA extracted from posterior part of dorsal fin muscle tissues and Nanodrop and Bioanalyzer was used to check the quality of RNA. Gene expression of PPAR α, β and γ were determined by RT-PCR. The expression of genes of interest was measured relative to control group after normalization to three reference genes. Total protein concentration was calculated by Bradford method, and protein expression was determined with primary PPARγ antibody by western blot. All data were analyzed by ANOVA followed by Benjamini-Hochberg and Bonferroni tests. Probability values <0.05 considered significant. Bactocell® and butyrate groups showed significantly lower PPARα expression. PPARβ and γ were not significantly different among groups. PPARγ mRNA expression was approximately consistent with protein expression pattern, except than butyrate group showed lower mRNA level. The order of PPARγ expression was Bactocell® > soy meal > butyrate > krill meal > control respectively. PPARβ gene expression decreased more in soy meal > butyrate > krill meal > Bactocell® > control groups respectively. In conclusion, the increased expression of PPARγ and α is proposed to represent a reduction tendency of lipid storage in fish fed by Bactocell®, butyrate, soy and krill meal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aquaculture" title="aquaculture">aquaculture</a>, <a href="https://publications.waset.org/abstracts/search?q=blotting%20western" title=" blotting western"> blotting western</a>, <a href="https://publications.waset.org/abstracts/search?q=gene%20expression" title=" gene expression"> gene expression</a>, <a href="https://publications.waset.org/abstracts/search?q=krill%20protein%20extract" title=" krill protein extract"> krill protein extract</a>, <a href="https://publications.waset.org/abstracts/search?q=prebiotics" title=" prebiotics"> prebiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=probiotics" title=" probiotics"> probiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=Salmo%20salar" title=" Salmo salar"> Salmo salar</a> </p> <a href="https://publications.waset.org/abstracts/79615/transcriptomic-and-translational-regulation-of-peroxisome-proliferator-activated-receptors-after-different-feedings-in-salmon" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79615.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">225</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> Automated Computer-Vision Analysis Pipeline of Calcium Imaging Neuronal Network Activity Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20Oluigbo">David Oluigbo</a>, <a href="https://publications.waset.org/abstracts/search?q=Erik%20Hemberg"> Erik Hemberg</a>, <a href="https://publications.waset.org/abstracts/search?q=Nathan%20Shwatal"> Nathan Shwatal</a>, <a href="https://publications.waset.org/abstracts/search?q=Wenqi%20Ding"> Wenqi Ding</a>, <a href="https://publications.waset.org/abstracts/search?q=Yin%20Yuan"> Yin Yuan</a>, <a href="https://publications.waset.org/abstracts/search?q=Susanna%20Mierau"> Susanna Mierau</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Calcium imaging is an established technique in neuroscience research for detecting activity in neural networks. Bursts of action potentials in neurons lead to transient increases in intracellular calcium visualized with fluorescent indicators. Manual identification of cell bodies and their contours by experts typically takes 10-20 minutes per calcium imaging recording. Our aim, therefore, was to design an automated pipeline to facilitate and optimize calcium imaging data analysis. Our pipeline aims to accelerate cell body and contour identification and production of graphical representations reflecting changes in neuronal calcium-based fluorescence. Methods: We created a Python-based pipeline that uses OpenCV (a computer vision Python package) to accurately (1) detect neuron contours, (2) extract the mean fluorescence within the contour, and (3) identify transient changes in the fluorescence due to neuronal activity. The pipeline consisted of 3 Python scripts that could both be easily accessed through a Python Jupyter notebook. In total, we tested this pipeline on ten separate calcium imaging datasets from murine dissociate cortical cultures. We next compared our automated pipeline outputs with the outputs of manually labeled data for neuronal cell location and corresponding fluorescent times series generated by an expert neuroscientist. Results: Our results show that our automated pipeline efficiently pinpoints neuronal cell body location and neuronal contours and provides a graphical representation of neural network metrics accurately reflecting changes in neuronal calcium-based fluorescence. The pipeline detected the shape, area, and location of most neuronal cell body contours by using binary thresholding and grayscale image conversion to allow computer vision to better distinguish between cells and non-cells. Its results were also comparable to manually analyzed results but with significantly reduced result acquisition times of 2-5 minutes per recording versus 10-20 minutes per recording. Based on these findings, our next step is to precisely measure the specificity and sensitivity of the automated pipeline’s cell body and contour detection to extract more robust neural network metrics and dynamics. Conclusion: Our Python-based pipeline performed automated computer vision-based analysis of calcium image recordings from neuronal cell bodies in neuronal cell cultures. Our new goal is to improve cell body and contour detection to produce more robust, accurate neural network metrics and dynamic graphs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calcium%20imaging" title="calcium imaging">calcium imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20vision" title=" computer vision"> computer vision</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20activity" title=" neural activity"> neural activity</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20networks" title=" neural networks"> neural networks</a> </p> <a href="https://publications.waset.org/abstracts/161680/automated-computer-vision-analysis-pipeline-of-calcium-imaging-neuronal-network-activity-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161680.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">7</span> Metal Contaminants in River Water and Human Urine after an Episode of Major Pollution by Mining Wastes in the Kasai Province of DR Congo</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Remy%20Mpulumba%20Badiambile">Remy Mpulumba Badiambile</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Musa%20Obadia"> Paul Musa Obadia</a>, <a href="https://publications.waset.org/abstracts/search?q=Malick%20Useni%20Mutayo"> Malick Useni Mutayo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeef%20Numbi%20Mukanya"> Jeef Numbi Mukanya</a>, <a href="https://publications.waset.org/abstracts/search?q=Patient%20Nkulu%20Banza"> Patient Nkulu Banza</a>, <a href="https://publications.waset.org/abstracts/search?q=Tony%20Kayembe%20Kitenge"> Tony Kayembe Kitenge</a>, <a href="https://publications.waset.org/abstracts/search?q=Erik%20Smolders"> Erik Smolders</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Fran%C3%A7ois%20Picron"> Jean-François Picron</a>, <a href="https://publications.waset.org/abstracts/search?q=Vincent%20Haufroid"> Vincent Haufroid</a>, <a href="https://publications.waset.org/abstracts/search?q=C%C3%A9lestin%20Banza%20Lubaba%20Nkulu"> Célestin Banza Lubaba Nkulu</a>, <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Nemery"> Benoit Nemery</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: In July 2021, the Tshikapa river became heavily polluted by mining wastes from a diamond mine in neighboring Angola, leading to massive killing of fish, as well as disease and even deaths among residents living along the Tshikapa and Kasai rivers, a major contributory of the Congo river. The exact nature of the pollutants was unknown. Methods: In a cross-sectional study conducted in the city of Tshikapa in August 2021, we enrolled by opportunistic sampling 65 residents (11 children < 16y) living alongside the polluted rivers and 65 control residents (5 children) living alongside a non-affected portion of the Kasai river (upstream from the Tshikapa-Kasai confluence). We administered a questionnaire and obtained spot urine samples for measurements of thiocyanate (a metabolite of cyanide) and 26 trace metals (by ICP-MS). Metals (and pH) were also measured in samples of river water. Results: Participants from both groups consumed river water. In the area affected by the pollution, most participants had eaten dead fish. Prevalences of reported health symptoms were higher in the exposed group than among controls: skin rashes (52% vs 0%), diarrhea (40% vs 8%), abdominal pain (8% vs 3%), nausea (3% vs 0%). In polluted water, concentrations [median (range)] were only higher for nickel [(2.2(1.4–3.5)µg/L] and uranium [78(71–91)ng/L] than in non-polluted water [0.8(0.6–1.9)µg/L; 9(7–19)ng/L]. In urine, concentrations [µg/g creatinine, median(IQR)] were significantly higher in the exposed group than in controls for lithium [19.5(12.4–27.3) vs 6.9(5.9–12.1)], thallium [0.41(0.31–0.57) vs 0.19(0.16–0.39)], and uranium [0.026(0.013–0.037)] vs 0.012(0.006–0.024)]. Other elements did not differ between the groups, but levels were higher than reference values for several metals (including manganese, cobalt, nickel, and lead). Urinary thiocyanate concentrations did not differ. Conclusion: This study, after an ecological disaster in the DRC, has documented contamination of river water by nickel and uranium and high urinary levels of some trace metals among affected riverine populations. However, the exact cause of the massive fish kill and disease among residents remains elusive. The capacity to rapidly investigate toxic pollution events must be increased in the area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metal%20contaminants" title="metal contaminants">metal contaminants</a>, <a href="https://publications.waset.org/abstracts/search?q=river%20water%20and%20human%20urine" title=" river water and human urine"> river water and human urine</a>, <a href="https://publications.waset.org/abstracts/search?q=pollution%20by%20mining%20wastes" title=" pollution by mining wastes"> pollution by mining wastes</a>, <a href="https://publications.waset.org/abstracts/search?q=DR%20Congo" title=" DR Congo"> DR Congo</a> </p> <a href="https://publications.waset.org/abstracts/155385/metal-contaminants-in-river-water-and-human-urine-after-an-episode-of-major-pollution-by-mining-wastes-in-the-kasai-province-of-dr-congo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155385.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">157</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> Investigation of the Effects of Visually Disabled and Typical Development Students on Their Multiple Intelligence by Applying Abacus and Right Brain Training</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sidika%20Di%CC%87l%C5%9Fad%20Kaya">Sidika Di̇lşad Kaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20Seli%CC%87m%20Kaya"> Ahmet Seli̇m Kaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibrahi%CC%87m%20Eri%CC%87k"> Ibrahi̇m Eri̇k</a>, <a href="https://publications.waset.org/abstracts/search?q=Havva%20Yaldiz"> Havva Yaldiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Yal%C3%A7in%20Kaya"> Yalçin Kaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to reveal the effects of right brain development on reading, comprehension, learning and concentration levels and rapid processing skills in students with low vision and students with standard development, and to explore the effects of right and left brain integration on students' academic success and the permanence of the learned knowledge. A total of 68 students with a mean age of 10.01±0.12 were included in the study, 58 of them with standard development, 9 partially visually impaired and 1 totally visually disabled student. The student with a total visual impairment could not participate in the reading speed test due to her total visual impairment. The following data were measured in the participant students before the project; Reading speed measurement in 1 minute, Reading comprehension questions, Burdon attention test, 50 questions of math quiz timed with a stopwatch. Participants were trained for 3 weeks, 5 days a week, for a total of two hours a day. In this study, right-brain developing exercises were carried out with the use of an abacus, and it was aimed to develop both mathematical and attention of students with questions prepared with numerical data taken from fairy tale activities. Among these problems, the study was supported with multiple-choice, 5W (what, where, who, why, when?), 1H (how?) questions along with true-false and fill-in-the-blank activities. By using memory cards, students' short-term memories were strengthened, photographic memory studies were conducted and their visual intelligence was supported. Auditory intelligence was supported by aiming to make calculations by using the abacus in the minds of the students with the numbers given aurally. When calculating the numbers by touching the real abacus, the development of students' tactile intelligence is enhanced. Research findings were analyzed in SPSS program, Kolmogorov Smirnov test was used for normality analysis. Since the variables did not show normal distribution, Wilcoxon test, one of the non-parametric tests, was used to compare the dependent groups. Statistical significance level was accepted as 0.05. The reading speed of the participants was 83.54±33.03 in the pre-test and 116.25±38.49 in the post-test. Narration pre-test 69.71±25.04 post-test 97.06±6.70; BURDON pretest 84.46±14.35 posttest 95.75±5.67; rapid math processing skills pretest 90.65±10.93, posttest 98.18±2.63 (P<0.05). It was determined that the pre-test and post-test averages of students with typical development and students with low vision were also significant for all four values (p<0.05). As a result of the data obtained from the participants, it is seen that the study was effective in terms of measurement parameters, and the findings were statistically significant. Therefore, it is recommended to use the method widely. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abacus" title="Abacus">Abacus</a>, <a href="https://publications.waset.org/abstracts/search?q=reading%20speed" title=" reading speed"> reading speed</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20intelligences" title=" multiple intelligences"> multiple intelligences</a>, <a href="https://publications.waset.org/abstracts/search?q=right%20brain%20training" title=" right brain training"> right brain training</a>, <a href="https://publications.waset.org/abstracts/search?q=visually%20impaired" title=" visually impaired"> visually impaired</a> </p> <a href="https://publications.waset.org/abstracts/146310/investigation-of-the-effects-of-visually-disabled-and-typical-development-students-on-their-multiple-intelligence-by-applying-abacus-and-right-brain-training" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146310.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">183</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> Mechanical Testing of Composite Materials for Monocoque Design in Formula Student Car</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erik%20Vass%C3%B8y%20Olsen">Erik Vassøy Olsen</a>, <a href="https://publications.waset.org/abstracts/search?q=Hirpa%20G.%20Lemu"> Hirpa G.

The design of the chassis or the frame is a key component of the competition because the weight and stiffness properties are directly related with the performance of the car and the safety of the driver. In addition, a reduced weight of the chassis has a direct influence on the design of other components in the car. Among others, it improves the power to weight ratio and the aerodynamic performance. As the power output of the engine or the battery installed in the car is limited to 80 kW, increasing the power to weight ratio demands reduction of the weight of the chassis, which represents the major part of the weight of the car. In order to reduce the weight of the car, ION Racing team from the University of Stavanger, Norway, opted for a monocoque design. To ensure fulfilment of the above-mentioned requirements of the chassis, the monocoque design should provide sufficient torsional stiffness and absorb the impact energy in case of a possible collision. The study reported in this article is based on the requirements for Formula Student competition. As part of this study, diverse mechanical tests were conducted to determine the mechanical properties and performances of the monocoque design. Upon a comprehensive theoretical study of the mechanical properties of sandwich composite materials and the requirements of monocoque design in the competition rules, diverse tests were conducted including 3-point bending test, perimeter shear test and test for absorbed energy. The test panels were homemade and prepared with an equivalent size of the side impact zone of the monocoque, i.e. 275 mm x 500 mm so that the obtained results from the tests can be representative. Different layups of the test panels with identical core material and the same number of layers of carbon fibre were tested and compared. Influence of the core material thickness was also studied. Furthermore, analytical calculations and numerical analysis were conducted to check compliance to the stated rules for Structural Equivalency with steel grade SAE/AISI 1010. The test results were also compared with calculated results with respect to bending and torsional stiffness, energy absorption, buckling, etc. The obtained results demonstrate that the material composition and strength of the composite material selected for the monocoque design has equivalent structural properties as a welded frame and thus comply with the competition requirements. The developed analytical calculation algorithms and relations will be useful for future monocoque designs with different lay-ups and compositions. <p class="card-text"><strong>Keywords:</strong> <a
