fundamental soil practice with different soil disturbance intensities and unique implications in soil organic carbon, soil structure, and nutrient dynamics. However, the implication of tillage practice on soil organic carbon and soil health is complex and specific to the context. it study evaluated soil health status based on soil carbon sequestration and pools, soil aggregation, and nutrient use under two different tillage practices: conventional and minimum tillage. The results of our study are consistent with the hypothesis that, over time, minimum tillage typically boosts soil health in the 0-10 cm soil layer. Compared to the conventional practice (19.36 t C ha-1) there was a significant accumulation of soil organic carbon (0-30 cm) in the minimum-tillage practice (23.21 t C ha-1). Below 10 cm depth, the soil organic carbon stocks are close to that of the conventional layer (0-30 cm). Soil aggregate stability was improved under conservative tillage, due to soil carbon improvement which facilitated a greater volume of mesopores and micropores. Total nitrogen (TN), available potassium (AK) and phosphorus (AP) content in 0-10 cm depth under minimum-tillage practice were 26%, 6% and 32%, greater respectively, compared to the conventional treatment. Overall, the TN, AP and AK values decreased with depth within the soil profiles as a consequence of soil practice and minimum disturbance. The data show that minimum tillage is a sustainable and effective management practice that maintain soil health with soil carbon increase and efficient nutrient use. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=minimum%20tillage" title="minimum tillage">minimum tillage</a>, <a href="https://publications.waset.org/abstracts/search?q=conventional%20tillage" title=" conventional tillage"> conventional tillage</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20organic%20carbon" title=" soil organic carbon"> soil organic carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrients" title=" nutrients"> nutrients</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20aggregation" title=" soil aggregation"> soil aggregation</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20health" title=" soil health"> soil health</a> </p> <a href="https://publications.waset.org/abstracts/194602/impact-of-different-tillage-practices-on-soil-health-status-carbon-storage-and-pools-soil-aggregation-and-nutrient-use" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194602.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">11</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">107</span> To Evaluate the Function of Cardiac Viability After Administration of I131</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Baburao%20Ganpat%20Apte">Baburao Ganpat Apte</a>, <a href="https://publications.waset.org/abstracts/search?q=Gajodhar"> Gajodhar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: diopathic Parkinson’s disease (PD) is the most common neurodegenerative disorder. Early PD may present a diagnostic challenge with broad differential diagnoses that are not associated with striatal dopamine deficiency. This test was performed by using special type of radioactive precursor which was made available through our logistics. 131I-TOPA L-6-[131I] Iodo-3,4-Trihydroxyphenylalnine (131I -TOPA) is a positron emission tomography (PET) agent that measures the uptake of dopamine precursors for assessment of presynaptic dopaminergic integrity and has been shown to accurately reflect the sign of nervous mind going in patients suffers from monoaminergic disturbances in PD. Both qualitative and quantitative analyses of the scans were performed. Therefore, the early clinical diagnosis alone may be accurate and this reinforces the importance of functional imaging targeting the patholigically of the disease process. The patient’s medical records were then assessed for length of follow-up, response to levotopa, clinical course of sickness, and usually though of symptoms at time of 131I -TOPA PET. A respective analysis was carried out for all patients that gone through 131I -TOPA PET brain scan for motor symptoms suspicious for PD between 2000 - 2006. The eventual diagnosis by the referring neurologist, movement therapist, physiotherapist, was used as the accurate measurements in standard for further analysis. In this study, our goal to illustrate our local experience to determine the accuracy of 131I -TOPA PET for diagnosis of PD. We studied a total of 48 patients. Of the 25 scans, it found that one was a false negative, 40 were true positives, and 7 were true negatives. The resultant values are Sensitivity 90.4% (95% CI: 100%-71.3%), Specificity 100% (92% CI: 100%-58.0%), PPV 100% (91% CI 100%-75.7%), and NPV 80.5% (95% CI: 92.5%-48.5%). Result: Twenty-three patients were found in the initial query, and 1 were excluded (2 uncertain diagnosis, 2 inadequate follow-up). Twenty-eight patients (28 scans) remained with 15 males (62%) and 8 females (30%). All the patients had a clinical follow-up of at least 3 years, however the median length of follow-up was 5.5 years (range: 2-8 years). The median age at scan time was 51.2 years (range: 35-75) <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=18F-TOPA" title="18F-TOPA">18F-TOPA</a>, <a href="https://publications.waset.org/abstracts/search?q=petct" title=" petct"> petct</a>, <a href="https://publications.waset.org/abstracts/search?q=parkinson%E2%80%99s%20disease" title=" parkinson’s disease"> parkinson’s disease</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiac" title=" cardiac"> cardiac</a> </p> <a href="https://publications.waset.org/abstracts/189379/to-evaluate-the-function-of-cardiac-viability-after-administration-of-i131" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189379.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">27</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">106</span> Implementation of a Low-Cost Instrumentation for an Open Cycle Wind Tunnel to Evaluate Pressure Coefficient </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cristian%20P.%20Topa">Cristian P.

However, the experiment instrumentation usually is expensive, and hence, each test implies a incremented in design cost. The aim of this work is to select and implement a low-cost static pressure data acquisition system for a NACA 2412 airfoil in an open cycle wind tunnel. This work compares wind tunnel experiment with Computational Fluid Dynamics (CFD) simulation and parametric analysis. The experiment was evaluated at Reynolds of 1.65 <em>e<sup>5</sup></em>, with increasing angles from -5° to 15°. The comparison between the approaches show good enough accuracy, between the experiment and CFD, additional parametric analysis results differ widely from the other methods, which complies with the lack of accuracy of the lateral approach due its simplicity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20tunnel" title="wind tunnel">wind tunnel</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20cost%20instrumentation" title=" low cost instrumentation"> low cost instrumentation</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20testing" title=" experimental testing"> experimental testing</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD%20simulation" title=" CFD simulation"> CFD simulation</a> </p> <a href="https://publications.waset.org/abstracts/88363/implementation-of-a-low-cost-instrumentation-for-an-open-cycle-wind-tunnel-to-evaluate-pressure-coefficient" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88363.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">180</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">105</span> Komedya: St. Denis' Philippine Theater in the US</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nenita%20Pambid%20Domingo">Nenita Pambid Domingo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The komedya otherwise known as moro-moro or pretending to be Moors, is a traditional Filipino play in the vernacular adapted from the Spanish comedia de capa y espada. It was used by Spanish colonizers in the Philippines, circa 1766 to evangelize and strengthen the faith of Indios or Filipino natives to Christianity. Unlike the Moros y Cristianos festival held all over Spain celebrating the Reconquista from the 8th to the 15th century, the Philippine Moro-Moro or Komedya is a romance between a Muslim and a Christian and the battles between Christians and Moros, where the Moros are always defeated and the Muslim prince is converted to the Christian faith and marries the Christian princess at the end of the play. For over 200 years, the komedya has been part of the Filipinos’ life and has been dubbed by some Philippine scholars as the Philippine’s national theater. Until now postings of performances in different parts of the Philippines in different Philippine languages are uploaded at youtube. In the US, “San Dionisio sa America (SDA),” an organization of natives from Barrio San Dionisio, Parañaque, Philippines has been performing the komedya for the past 16 years during their town’s fiesta, in honor of the barrio's patron saints St Denis of Paris, France and Saint Joseph whom the devotees fondly call "Tata Dune" and "Tata Hosep". The komedya performed in the US is infused with modern elements in the production and content, but retain the basic form in verse and the stylized war dance, marches, and singsong delivery of lines. Most of the Celebras or town fiestas and komedya performances are held at The Barnsdall Art Park and Gallery Theatre in Hollywood, Los Angeles. The presentation will focus on the linguistic and content analysis of the Tagalog verses in the 2010 komedya entitled Mga Prinsesa ng Cordova (The Princesses of Cordova) publicized as a modern komedya. The presentation will also touch on the healing function of the language and performance that is part of the town’s religious festivities. It will also look into the aesthetics of the production, audience reception, participation of the sponsors, producers called Hermana/Hermano Mayor, the performers who are a mix of Filipinos from the Philippines and Filipino-Americans who are starting to lose the Tagalog language and the non-Filipino participants, as well as the general audience who are from Parañaque and those not from Parañaque, who come to witness the event and enjoy the festivities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=devotion" title="devotion">devotion</a>, <a href="https://publications.waset.org/abstracts/search?q=diaspora%20nationalism" title=" diaspora nationalism"> diaspora nationalism</a>, <a href="https://publications.waset.org/abstracts/search?q=komedya" title=" komedya"> komedya</a>, <a href="https://publications.waset.org/abstracts/search?q=st.%20denis%20of%20Paris" title=" st. denis of Paris"> st. denis of Paris</a>, <a href="https://publications.waset.org/abstracts/search?q=France" title=" France"> France</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20Philippine%20theater" title=" traditional Philippine theater"> traditional Philippine theater</a> </p> <a href="https://publications.waset.org/abstracts/83440/komedya-st-denis-philippine-theater-in-the-us" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83440.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">3208</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">104</span> Algorithms of ABS-Plastic Extrusion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dmitrii%20Starikov">Dmitrii Starikov</a>, <a href="https://publications.waset.org/abstracts/search?q=Evgeny%20Rybakov"> Evgeny Rybakov</a>, <a href="https://publications.waset.org/abstracts/search?q=Denis%20Zhuravlev"> Denis Zhuravlev</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Plastic for 3D printing is very necessary material part for printers.

The need for such a study was generated by the key objective of the ERL-Emergency project. The project aims to develop a system of collaborative robots for emergency response. The system consists of two robots: unmanned ground vehicles (UGV) on tracks and the second is an AUV. The system of collaborative robots, AUV and UGV, will be used to perform missions of monitoring, intervention, and rescue. The main mission of the AUV is to dive into the maritime space of an industrial port to detect possible leaks in a pipeline transporting petroleum products. Another mission is to close and open the valves with which the pipes are provided. Finally, you will need to be able to lift a manikin to the surface, which you can take to land. Numerical analysis was performed by the finite element method (FEM). The conditions for immersing the AUV at 100 m depth were simulated, and the calculations for different fluid flow rates were repeated. From a structural point of view, the stiffening areas and the enclosures in which the command-and-control elements and the accumulators are located have been especially analyzed. The conclusion of this research is that the AUV meets very well the established requirements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytical-numerical" title="analytical-numerical">analytical-numerical</a>, <a href="https://publications.waset.org/abstracts/search?q=emergency" title=" emergency"> emergency</a>, <a href="https://publications.waset.org/abstracts/search?q=FEM" title=" FEM"> FEM</a>, <a href="https://publications.waset.org/abstracts/search?q=robotics" title=" robotics"> robotics</a>, <a href="https://publications.waset.org/abstracts/search?q=underwater" title=" underwater"> underwater</a> </p> <a href="https://publications.waset.org/abstracts/134474/aspects-regarding-the-structural-behaviour-of-autonomous-underwater-vehicle-for-emergency-response" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134474.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">150</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">92</span> Elaboration and Characterization of CdxZn1-XS Thin Films Deposed by Chemical Bath Deposition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zellagui%20Rahima">Zellagui Rahima</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaumont%20Denis"> Chaumont Denis</a>, <a href="https://publications.waset.org/abstracts/search?q=Boughelout%20Abderrahman"> Boughelout Abderrahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Adnane%20Mohamed"> Adnane Mohamed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Thin films of CdxZn1-xS were deposed by chemical bath deposition on glass substrates for photovoltaic applications.

Among those, mandatory municipal wastewater treatment is included. Our study involved Municipal Wastewater Treatment Plant (MWWTP) of Galati. MWWTP began its activity by the end of 2011 and technology is one of the most modern used in the EU. Moreover, to our knowledge, it is the first technology of this kind used in the region. Until commissioning, municipal wastewater was discharged directly into the Danube without any treatment. Besides the benefits of depollution, a new problem has arisen: the accumulation of increasingly large sewage sludge. Therefore, it is extremely important to find economically feasible and environmentally friendly solutions. One of the most feasible methods of disposing of sewage sludge is their use on agricultural land. Sewage sludge can be used in agriculture if monitored in terms of physicochemical properties (pH, nutrients, heavy metals, etc.), in order not to contribute to pollution in soils and not to affect chemical and biological balances, which are relatively fragile. In this paper, 16 physico-chemical parameters were monitored. Experimental testings were realised on waste water samples, sewage sludge results and treated water samples. Testing was conducted with electrochemichal methods (pH, conductivity, TDS); parameters N-total (mg/L), P-total (mg/L), N-NH4 (mg/L), N-NO2 (mg/L), N-NO3 (mg/L), Fe-total (mg/L), Cr-total (mg/L), Cu (mg/L), Zn (mg/L), Cd (mg/L), Pb (mg/L), Ni (mg/L) were determined by spectrophotometric methods using a spectrophotometer NOVA 60 and specific kits. Analyzing the results, we concluded that Sewage sludges, although containing heavy metals, are in small quantities and will not affect the land on which they will be deposited. Also, the amount of nutrients contained are appreciable. These features indicate that the sludge can be safely used in agriculture, with the advantage that they represent a cheap fertilizer.

Generally, these applications help people to achieve their goals based on scientific research and input data. Still, they do not always explain how those three are related, e.g. by making implicit assumptions about goals that hold for many but not for all. We present a seven-step method for designing health and wellbeing AIs considering goal setting, measurable results, real-time indicators, analytics, visual representations, communication, and feedback. It can help engineers as guidance in developing apps, recommendation algorithms, and interfaces that support humans in their decision-making without patronization. To illustrate the method, we create a recommender AI for tiny wellbeing habits and run a small case study, including a survey. From the results, we infer how people perceive the relationship between them and the AI and to what extent it helps them to achieve their goals. We review our seven-step engineering method and suggest modifications for the next iteration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=recommender%20systems" title="recommender systems">recommender systems</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20language%20processing" title=" natural language processing"> natural language processing</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20apps" title=" health apps"> health apps</a>, <a href="https://publications.waset.org/abstracts/search?q=engineering%20methods" title=" engineering methods"> engineering methods</a> </p> <a href="https://publications.waset.org/abstracts/155182/ai-in-health-and-wellbeing-a-seven-step-engineering-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155182.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">165</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">89</span> Transforming Public Administration in the Digital Era: Challenges and Opportunities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Catalina%20Oana%20Dumitrescu">Catalina Oana Dumitrescu</a>, <a href="https://publications.waset.org/abstracts/search?q=Andreea%20L.%20Drugau-constantin"> Andreea L.

This paper explores how new digital technologies – including artificial intelligence, blockchain, big data and e-governance solutions – are reshaping the functioning of public administrations globally. In addition to the obvious opportunities to streamline and optimize processes, digital transformation brings with it major challenges, such as cyber security, personal data protection, resistance to change and the need to develop new skills for employees. The paper aims to provide a discussion platform for public administration experts, policy makers and technology innovators to consider how governments can balance the benefits and risks of digital transformation. Topics such as the reconfiguration of administrative processes, the creation of interoperable government systems, the involvement of citizens in public decisions through digital platforms, and solutions for reducing the digital gap between developed and developing regions will be addressed. In conclusion, the digital transformation of public administration is not only an opportunity for modernization, but also a necessity to respond to the new demands and challenges of contemporary society. This paper will provide new insights into the role of technology in improving the quality of governance and public services. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=public%20administration" title="public administration">public administration</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20ERA" title=" digital ERA"> digital ERA</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a>, <a href="https://publications.waset.org/abstracts/search?q=government%20systems" title=" government systems"> government systems</a>, <a href="https://publications.waset.org/abstracts/search?q=global" title=" global"> global</a> </p> <a href="https://publications.waset.org/abstracts/192568/transforming-public-administration-in-the-digital-era-challenges-and-opportunities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192568.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">17</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">88</span> Influence of Different Asymmetric Rolling Processes on Shear Strain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Pesin">Alexander Pesin</a>, <a href="https://publications.waset.org/abstracts/search?q=Denis%20Pustovoytov"> Denis Pustovoytov</a>, <a href="https://publications.waset.org/abstracts/search?q=Mikhail%20Sverdlik"> Mikhail Sverdlik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Materials with ultrafine-grained structure and unique physical and mechanical properties can be obtained by methods of severe plastic deformation, which include processes of asymmetric rolling (AR). Asymmetric rolling is a very effective way to create ultrafine-grained structures of metals and alloys. Since the asymmetric rolling is a continuous process, it has great potential for industrial production of ultrafine-grained structure sheets. Basic principles of asymmetric rolling are described in detail in scientific literature. In this work finite element modeling of asymmetric rolling and metal forming processes in multiroll gauge was performed. Parameters of the processes which allow achieving significant values of shear strain were defined. The results of the study will be useful for the research of the evolution of ultra-fine metal structure in asymmetric rolling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20rolling" title="asymmetric rolling">asymmetric rolling</a>, <a href="https://publications.waset.org/abstracts/search?q=equivalent%20strain" title=" equivalent strain"> equivalent strain</a>, <a href="https://publications.waset.org/abstracts/search?q=FEM" title=" FEM"> FEM</a>, <a href="https://publications.waset.org/abstracts/search?q=multiroll%20gauge" title=" multiroll gauge"> multiroll gauge</a>, <a href="https://publications.waset.org/abstracts/search?q=profile" title=" profile"> profile</a>, <a href="https://publications.waset.org/abstracts/search?q=severe%20plastic%20deformation" title=" severe plastic deformation"> severe plastic deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20strain" title=" shear strain"> shear strain</a>, <a href="https://publications.waset.org/abstracts/search?q=sheet" title=" sheet"> sheet</a> </p> <a href="https://publications.waset.org/abstracts/6490/influence-of-different-asymmetric-rolling-processes-on-shear-strain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6490.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">265</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">87</span> Determinants of Effective Food Waste Management in an Urban Area in Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nazia%20Jabeen">Nazia Jabeen</a>, <a href="https://publications.waset.org/abstracts/search?q=Denis%20Hyams-Ssekasi"> Denis Hyams-Ssekasi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study focuses on the determinants of food waste management (FWM) in one of the urban areas of Pakistan. One hundred and two households from the urban areas of Pakistan took part in the study via self-completed questionnaires, and data were analyzed. The research findings indicate that food waste management is a recurring issue, and households must do more to minimize or create business opportunities. Most households agree that food waste has significant implications for the community if not utilized and managed correctly. The value creation deriving from this zero-value resource provides a platform where householders see the benefit of food waste management. Based on the findings, this study acknowledges that food waste has significant economic and social impacts on the community. It concludes that minimization and optimum utilization of food waste create a pathway to business opportunities in urban areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=economic" title="economic">economic</a>, <a href="https://publications.waset.org/abstracts/search?q=social" title=" social"> social</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20waste%20management" title=" food waste management"> food waste management</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20opportunities" title=" business opportunities"> business opportunities</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20creation" title=" value creation"> value creation</a> </p> <a href="https://publications.waset.org/abstracts/164686/determinants-of-effective-food-waste-management-in-an-urban-area-in-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164686.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">86</span> Sampling Error and Its Implication for Capture Fisheries Management in Ghana</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Temiloluwa%20J.%20Akinyemi">Temiloluwa J.

However, the misperception of biophysical dynamics owing to a lack of adequate scientific data has contributed to the suboptimal management in marine capture fisheries. This is because yield and catch potentials are sensitive to the quality of catch and effort data. Yet, studies on fisheries data collection practices in developing countries are hard to find. This study investigates the data collection methods utilized by fisheries technical officers within the four fishing regions of Ghana. We found that the officers employed data collection and sampling procedures which were not consistent with the technical guidelines curated by FAO. For example, 50 instead of 166 landing sites were sampled, while 290 instead of 372 canoes were sampled. We argue that such sampling errors could result in the over-capitalization of capture fish stocks and significant losses in resource rents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fisheries%20data%20quality" title="Fisheries data quality">Fisheries data quality</a>, <a href="https://publications.waset.org/abstracts/search?q=fisheries%20management" title=" fisheries management"> fisheries management</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghana" title=" Ghana"> Ghana</a>, <a href="https://publications.waset.org/abstracts/search?q=Sustainable%20Fisheries" title=" Sustainable Fisheries"> Sustainable Fisheries</a> </p> <a href="https://publications.waset.org/abstracts/161493/sampling-error-and-its-implication-for-capture-fisheries-management-in-ghana" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161493.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">92</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">85</span> Impact of Machining Parameters on the Surface Roughness of Machined PU Block</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Louis%20Denis%20Kevin%20Catherine">Louis Denis Kevin Catherine</a>, <a href="https://publications.waset.org/abstracts/search?q=Raja%20Aziz%20Raja%20Ma%E2%80%99arof"> Raja Aziz Raja Ma’arof</a>, <a href="https://publications.waset.org/abstracts/search?q=Azrina%20Arshad"> Azrina Arshad</a>, <a href="https://publications.waset.org/abstracts/search?q=Sangeeth%20Suresh"> Sangeeth Suresh </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Machining parameters are very important in determining the surface quality of any material. In the past decade, some new engineering materials were developed for the manufacturing industry which created a need to conduct an investigation on the impact of the said parameters on their surface roughness. The polyurethane (PU) block is widely used in the automotive industry to manufacture parts such as checking fixtures that are used to verify the dimensional accuracy of automotive parts. In this paper, the design of experiment (DOE) was used to investigate the effect of the milling parameters on the PU block. Furthermore, an analysis of the machined surface chemical composition was done using scanning electron microscope (SEM). It was found that the surface roughness of the PU block is severely affected when PU undergoes a flood machining process instead of a dry condition. In addition, the step over and the silicon content were found to be the most significant parameters that influence the surface quality of the PU block. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polyurethane%20%28PU%29" title="polyurethane (PU)">polyurethane (PU)</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20of%20experiment%20%28DOE%29" title=" design of experiment (DOE)"> design of experiment (DOE)</a>, <a href="https://publications.waset.org/abstracts/search?q=scanning%20electron%20microscope%20%28SEM%29" title=" scanning electron microscope (SEM)"> scanning electron microscope (SEM)</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20roughness" title=" surface roughness"> surface roughness</a> </p> <a href="https://publications.waset.org/abstracts/20483/impact-of-machining-parameters-on-the-surface-roughness-of-machined-pu-block" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20483.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">521</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">84</span> Traditional Factors of States’ Economic Growth: Modern Patterns, Values and Limitations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Denis%20Ushakov">Denis Ushakov </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fast growing international migration as a factor of labor globalization now is one of the most important trends of world economy and determinant of social-political transformations.

As the orebody containing uranium most often contains a considerable value of other metals, particularly rare earth metals it has rendered feasible to recover the REM from the barren ISL solutions, from which the major uranium content has been removed. Ural Federal University (UrFU, Ekaterinburg, Russia) have performed joint research on the development of industrial technologies for the extraction of REM and Scandium compounds from Uranium ISL solutions. Leaching experiments at UrFU have been supported with multicomponent solution model. The experimental work combines solvent extraction with advanced ion exchange methodology in a pilot facility capable of treating 500 kg/hr of solids. The pilot allows for the recovery of a 99% concentrate of scandium oxide and collective concentrate with over 50 % REM content, with further recovery of heavy and light REM concentrates (99%). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extraction" title="extraction">extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20exchange" title=" ion exchange"> ion exchange</a>, <a href="https://publications.waset.org/abstracts/search?q=rare%20earth%20elements" title=" rare earth elements"> rare earth elements</a>, <a href="https://publications.waset.org/abstracts/search?q=scandium" title=" scandium"> scandium</a> </p> <a href="https://publications.waset.org/abstracts/88125/recovery-of-rare-earths-and-scandium-from-in-situ-leaching-solutions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88125.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">232</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">82</span> Reducing Component Stress during Encapsulation of Electronics: A Simulative Examination of Thermoplastic Foam Injection Molding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Constantin%20Ott">Constantin Ott</a>, <a href="https://publications.waset.org/abstracts/search?q=Dietmar%20Drummer"> Dietmar Drummer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The direct encapsulation of electronic components is an effective way of protecting components against external influences. In addition to achieving a sufficient protective effect, there are two other big challenges for satisfying the increasing demand for encapsulated circuit boards. The encapsulation process should be both suitable for mass production and offer a low component load. Injection molding is a method with good suitability for large series production but also with typically high component stress. In this article, two aims were pursued: first, the development of a calculation model that allows an estimation of the occurring forces based on process variables and material parameters. Second, the evaluation of a new approach for stress reduction by means of thermoplastic foam injection molding. For this purpose, simulation-based process data was generated with the Moldflow simulation tool. Based on this, component stresses were calculated with the calculation model. At the same time, this paper provided a model for estimating the forces occurring during overmolding and derived a solution method for reducing these forces. The suitability of this approach was clearly demonstrated and a significant reduction in shear forces during overmolding was achieved. It was possible to demonstrate a process development that makes it possible to meet the two main requirements of direct encapsulation in addition to a high protective effect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=encapsulation" title="encapsulation">encapsulation</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20reduction" title=" stress reduction"> stress reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=foam-injection-molding" title=" foam-injection-molding"> foam-injection-molding</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/145190/reducing-component-stress-during-encapsulation-of-electronics-a-simulative-examination-of-thermoplastic-foam-injection-molding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145190.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">126</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">81</span> Modal Analysis of a Cantilever Beam Using an Inexpensive Smartphone Camera: Motion Magnification Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Hassoun">Hasan Hassoun</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaafar%20Hallal"> Jaafar Hallal</a>, <a href="https://publications.waset.org/abstracts/search?q=Denis%20Duhamel"> Denis Duhamel</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Hammoud"> Mohammad Hammoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Hage%20Diab"> Ali Hage Diab</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to prove the accuracy of an inexpensive smartphone camera as a non-contact vibration sensor to recover the vibration modes of a vibrating structure such as a cantilever beam. A video of a vibrating beam is filmed using a smartphone camera and then processed by the motion magnification technique. Based on this method, the first two natural frequencies and their associated mode shapes are estimated experimentally and compared to the analytical ones. Results show a relative error of less than 4% between the experimental and analytical approaches for the first two natural frequencies of the beam. Also, for the first two-mode shapes, a Modal Assurance Criterion (MAC) value of above 0.9 between the two approaches is obtained. This slight error between the different techniques ensures the viability of a cheap smartphone camera as a non-contact vibration sensor, particularly for structures vibrating at relatively low natural frequencies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=modal%20analysis" title="modal analysis">modal analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=motion%20magnification" title=" motion magnification"> motion magnification</a>, <a href="https://publications.waset.org/abstracts/search?q=smartphone%20camera" title=" smartphone camera"> smartphone camera</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20vibration" title=" structural vibration"> structural vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=vibration%20modes" title=" vibration modes"> vibration modes</a> </p> <a href="https://publications.waset.org/abstracts/127525/modal-analysis-of-a-cantilever-beam-using-an-inexpensive-smartphone-camera-motion-magnification-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127525.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">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">80</span> Ways for Improving Citation of the Cyrillic Publications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victoria%20Y.%20Garnova">Victoria Y.

The use of supercapacitors as energy storage devices in hybrid energy harvesting systems allows the miniaturization of electronic structures for energy storage. This study is concerned with the concept of energy management capacitors – supercapacitors and the new electronic structures for energy storage used for energy harvesting devices. Supercapacitors are low-voltage devices, and electronic overvoltage protection is needed for powering the source. The power management device that uses these proposed new electronic structures for energy storage is better than conventional electronic structures used for this purpose, like rechargeable batteries, supercapacitors, and hybrid systems. A hybrid energy harvesting system with energy storage management is able to simultaneously use several energy sources with recovery from the environment. The power management device uses a summing electronic block to combine the electric power obtained from piezoelectric composite plates and from a photovoltaic conversion system. Also, an overvoltage protection circuit used as a voltage detector and an improved concept of charging supercapacitors is presented. The piezoelectric composite plates are realized only by pressing two printed circuit boards together without damaging or prestressing the piezoceramic elements. The photovoltaic conversion system has the advantage that the modules are covered with glass plates with nanostructured film of ZnO with the role of anti-reflective coating and to improve the overall efficiency of the solar panels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=supercapacitors" title="supercapacitors">supercapacitors</a>,
