summarizes the progress in the latest computational fluid dynamics research towards the modeling in of lost core viability in high-pressure die casting. High-pressure die casting is a process that is widely employed in the automotive and neighboring industries due to its advantages in casting quality and cost efficiency. The degrees of freedom are however somewhat limited as it has been so far difficult to use lost cores in the process. This is right now changing and the deployment of lost cores is considered a future growth potential for high-pressure die casting companies. The use of this technology itself is difficult though. The strength of the core material, as chiefly salt is used, is limited and experiments have shown that the cores will not hold under all circumstances and process designs. For this purpose, the publicly available CFD library foam-extend (OpenFOAM) is used, and two additional fluid models for incompressible and compressible two-phase flow are implemented as fluid solver models into the FSI library. For this purpose, the volume-of-fluid (VOF) methodology is used. The necessity for the fluid-structure interaction (FSI) approach is shown by a simple CFD model geometry. The model is benchmarked against analytical models and experimental data. Sufficient agreement is found with the analytical models and good agreement with the experimental data. An outlook on future developments concludes the paper. <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=fluid-structure%20interaction" title=" fluid-structure interaction"> fluid-structure interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=high-pressure%20die%20casting" title=" high-pressure die casting"> high-pressure die casting</a>, <a href="https://publications.waset.org/abstracts/search?q=multiphase%20flow" title=" multiphase flow"> multiphase flow</a> </p> <a href="https://publications.waset.org/abstracts/78928/towards-the-modeling-of-lost-core-viability-in-high-pressure-die-casting-a-fluid-structure-interaction-model-with-2-phase-flow-fluid-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78928.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">332</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">41</span> Exploring the Dark Side of IT Security: Delphi Study on Business’ Influencing Factors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tizian%20Matschak">Tizian Matschak</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilja%20Nastjuk"> Ilja Nastjuk</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephan%20K%C3%BChnel"> Stephan Kühnel</a>, <a href="https://publications.waset.org/abstracts/search?q=Simon%20Trang"> Simon Trang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We argue that besides well-known primary effects of information security controls (ISCs), namely confidentiality, integrity, and availability, ISCs can also have secondary effects. For example, while IT can add business value through impacts on business processes, ISCs can be a barrier and distort the relationship between IT and organizational value through the impact on business processes. By applying the Delphi method with 28 experts, we derived 27 business process influence dimensions of ISCs. Defining and understanding these mechanisms can change the common understanding of the cost-benefit valuation of IT security investments and support managers' effective and efficient decision-making. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=business%20process%20dimensions" title="business process dimensions">business process dimensions</a>, <a href="https://publications.waset.org/abstracts/search?q=dark%20side%20of%20information%20security" title=" dark side of information security"> dark side of information security</a>, <a href="https://publications.waset.org/abstracts/search?q=Delphi%20study" title=" Delphi study"> Delphi study</a>, <a href="https://publications.waset.org/abstracts/search?q=IT%20security%20controls" title=" IT security controls"> IT security controls</a> </p> <a href="https://publications.waset.org/abstracts/163415/exploring-the-dark-side-of-it-security-delphi-study-on-business-influencing-factors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163415.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">112</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">40</span> Heat and Mass Transfer Study of Supercooled Large Droplet Icing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Du%20Yanxia">Du Yanxia</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephan%20E.%20Bansmer"> Stephan E.

The behavior of ice and water was analyzed. The results show that under supercooled large droplet (SLD) icing conditions, the film flow is an important phonomena in icing accretion process. The pressure gradient, gravity and shear stress are the main factors affecting the film flow on icing surface, which has important influence on the shape and rate of icing. To predict SLD ice accretion accurately, the heat and mass transfer of ice and film flow should be taken into account. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SLD" title="SLD">SLD</a>, <a href="https://publications.waset.org/abstracts/search?q=aircraft" title=" aircraft"> aircraft</a>, <a href="https://publications.waset.org/abstracts/search?q=icing" title=" icing"> icing</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20and%20mass%20transfer" title=" heat and mass transfer"> heat and mass transfer</a> </p> <a href="https://publications.waset.org/abstracts/22845/heat-and-mass-transfer-study-of-supercooled-large-droplet-icing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22845.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">634</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">39</span> Synchrotron X-Ray Based Investigation of As and Fe Bonding Environment in Collard Green Tissue Samples at Different Growth Stages</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunil%20Dehipawala">Sunil Dehipawala</a>, <a href="https://publications.waset.org/abstracts/search?q=Aregama%20Sirisumana"> Aregama Sirisumana</a>, <a href="https://publications.waset.org/abstracts/search?q=stephan%20Smith"> stephan Smith</a>, <a href="https://publications.waset.org/abstracts/search?q=P.%20Schneider"> P.

The Fe absorption and the Fourier transform bond length information were used as a control comparison. The Fourier transform of the XAFS data revealed the coexistence of As (III) and As (V) in the As bonding environment inside the studied plant tissue samples, although the soil only had As (III).

Its value creates chances for users to profit from data sales and purchases. Users in data marketplaces, however, must share and trade data in a secure and trusted environment while maintaining their privacy. The first main contribution of this paper is to identify enabling technologies and challenges facing the development of decentralized data marketplaces. The second main contribution is to propose a decentralized data marketplace framework based on blockchain technology. The proposed framework enables sellers and buyers to transact with more confidence. Using a security deposit, the system implements a unique approach for enforcing honesty in data exchange among anonymous individuals. Before the transaction is considered complete, the system has a time frame. As a result, users can submit disputes to the arbitrators which will review them and respond with their decision. Use cases are presented to demonstrate how these technologies help data marketplaces handle issues and challenges. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blockchain" title="blockchain">blockchain</a>, <a href="https://publications.waset.org/abstracts/search?q=data" title=" data"> data</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20marketplace" title=" data marketplace"> data marketplace</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20contract" title=" smart contract"> smart contract</a>, <a href="https://publications.waset.org/abstracts/search?q=reputation%20system" title=" reputation system"> reputation system</a> </p> <a href="https://publications.waset.org/abstracts/149122/decentralized-data-marketplace-framework-using-blockchain-based-smart-contract" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149122.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">158</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">37</span> Assessment of the High-Speed Ice Friction of Bob Skeleton Runners</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agata%20Tomaszewska">Agata Tomaszewska</a>, <a href="https://publications.waset.org/abstracts/search?q=Timothy%20Kamps"> Timothy Kamps</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephan%20R.%20Turnock"> Stephan R.

It is believed that the friction between the runners and ice significantly contributes to the amount of the total energy loss during a bob skeleton descent. There is only limited available experimental data regarding the friction of bob skeleton runners or indeed steel on the ice at high sliding speeds ( > 20 m/s). Testing methods used to investigate the friction of steel on ice in winter sports have been outlined, and their accuracy and repeatability discussed. A system thinking approach was used to investigate the runner-ice interaction during sliding and create concept designs of three ice tribometers. The operational envelope of the bob skeleton system has been defined through mathematical modelling. Designs of a drum, linear and inertia pin-on-disk tribometers were developed specifically for bob skeleton runner testing with the requirement of reaching up to 40 m/s speed and facilitate fresh ice sliding. The design constraints have been outline and the proposed solutions compared based on the ease of operation, accuracy and the development cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bob%20skeleton" title="bob skeleton">bob skeleton</a>, <a href="https://publications.waset.org/abstracts/search?q=ice%20friction" title=" ice friction"> ice friction</a>, <a href="https://publications.waset.org/abstracts/search?q=high-speed%20tribometers" title=" high-speed tribometers"> high-speed tribometers</a>, <a href="https://publications.waset.org/abstracts/search?q=sliding%20friction" title=" sliding friction"> sliding friction</a> </p> <a href="https://publications.waset.org/abstracts/72268/assessment-of-the-high-speed-ice-friction-of-bob-skeleton-runners" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72268.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">261</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">36</span> The SOCI Strategy as a Method to Meet the Innovation Challenges of COVID-19</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victoria%20Wolf">Victoria Wolf</a>, <a href="https://publications.waset.org/abstracts/search?q=Renata%20Dobrucka"> Renata Dobrucka</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Prezkop"> Robert Prezkop</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephan%20Haubold"> Stephan Haubold</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The COVID-19 causes a worldwide crisis and has an impact in every dimension of the economy. Organizations with the ability to adapt to new developments and which innovate solutions for the disrupted world during and after the Corona crises have the opportunity to not only survive the crisis but rather to use new trends to implement new business models and gain advantage. In this context, startups seem to have better opportunities to manage the Corona crisis through their innovation-based nature. The main result of this paper is the understanding that by applying a startup orientated innovation (SOCI) strategy, established companies can be motivated to meet the challenge of COVID-19 in a similar way like startups. This result can be achieved by describing the role of innovation and a SOCI strategy as helpful methods for organizations to meet the coming challenges during and after the COVID-19 epidemics. In addition to this, this paper presents a practical application of SOCI through the PANDA approach of the Fresenius University of Applied Sciences in Germany and discuss it in the context of COVID-19 as an exemplary successful real-world implementation of SOCI strategy. <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=innovation" title=" innovation"> innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20innovation" title=" open innovation"> open innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=startup" title=" startup"> startup</a>, <a href="https://publications.waset.org/abstracts/search?q=soci%20framework" title=" soci framework"> soci framework</a> </p> <a href="https://publications.waset.org/abstracts/134180/the-soci-strategy-as-a-method-to-meet-the-innovation-challenges-of-covid-19" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134180.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">235</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">35</span> One-Dimension Model for Positive Displacement Pump with Cavitation Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Francesco%20Rizzuto">Francesco Rizzuto</a>, <a href="https://publications.waset.org/abstracts/search?q=Matthew%20Stickland"> Matthew Stickland</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephan%20Hannot"> Stephan Hannot</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The simulation of a positive displacement pump system with commercial software for Computer Fluid Dynamics (CFD), will result in an enormous computational effort due to the complexity of the pump system. This drawback restricts the use of it to a specific part of the pump in one simulation. This research focuses on developing an algorithm that provides a suitable result in agreement with experiment data, without that computational effort. The compressible equations are solved with an explicit algorithm. A comparison is presented between the FV method with Monotonic Upwind scheme for Conservative Laws (MUSCL) with slope limiter and experimental results. The source term for cavitation and friction is introduced into the algorithm with a slipping strategy and solved with a 4th order Runge-Kutta scheme (RK4). Different pumps are modeled and analyzed to evaluate the flexibility of the code. The simulation required minimal computation time and resources without compromising the accuracy of the simulation results. Therefore, this algorithm highlights the feasibility of pressure pulsation simulation as a design tool for an industrial purpose. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cavitation" title="cavitation">cavitation</a>, <a href="https://publications.waset.org/abstracts/search?q=diaphragm" title=" diaphragm"> diaphragm</a>, <a href="https://publications.waset.org/abstracts/search?q=DVCM" title=" DVCM"> DVCM</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20volume" title=" finite volume"> finite volume</a>, <a href="https://publications.waset.org/abstracts/search?q=MUSCL" title=" MUSCL"> MUSCL</a>, <a href="https://publications.waset.org/abstracts/search?q=positive%20displacement%20pump" title=" positive displacement pump"> positive displacement pump</a> </p> <a href="https://publications.waset.org/abstracts/98062/one-dimension-model-for-positive-displacement-pump-with-cavitation-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98062.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">155</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">34</span> Effect of Whole-Body Vibration Training on Self-Reported Physical Disability in Employees with Chronic Low-Back Pain: A Randomized Controlled Trial</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tobias%20Stephan%20Kaeding">Tobias Stephan Kaeding</a>, <a href="https://publications.waset.org/abstracts/search?q=Rebecca%20Schwarz"> Rebecca Schwarz</a>, <a href="https://publications.waset.org/abstracts/search?q=Momme%20K%C3%BCck"> Momme Kück</a>, <a href="https://publications.waset.org/abstracts/search?q=Lothar%20Stein"> Lothar Stein</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The goal of this randomized and controlled study is to examine whether whole-body vibration (WBV) training is able to reduce self-reported physical disability in office employees with chronic low-back pain. Materials and methods: 41 subjects (68.3% female/mean age 45.5 ± 9.1 years/mean BMI 26.6 ± 5.2) were randomly allocated to an intervention group (INT (n= 21)) or a control group (CON (n=20). The INT participated in WBV training 2.5 times per week for 3 months. The primary outcome was the change in the Roland and Morris disability questionnaire (RMQ) score over the study period. In addition, secondary outcomes included changes in the Oswestry Disability Index (ODI). Results: The compliance with the intervention in the INT reached a mean of 81.1% ± 31.2% with no long-lasting unwanted side effects. We found significant positive effects of 3 months of WBV training in the INT compared to the CON regarding the RMQ (p=0.027) and the ODI (p=0.002). Conclusions: WBV training seems to be an effective, safe and suitable intervention for the reduction of the self-reported physical disability in seated working employees with chronic low-back pain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=back%20pain" title="back pain">back pain</a>, <a href="https://publications.waset.org/abstracts/search?q=exercise" title=" exercise"> exercise</a>, <a href="https://publications.waset.org/abstracts/search?q=occupational%20health%20management" title=" occupational health management"> occupational health management</a>, <a href="https://publications.waset.org/abstracts/search?q=vibration%20training" title=" vibration training"> vibration training</a> </p> <a href="https://publications.waset.org/abstracts/68861/effect-of-whole-body-vibration-training-on-self-reported-physical-disability-in-employees-with-chronic-low-back-pain-a-randomized-controlled-trial" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68861.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">298</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> Nanocharacterization of PIII Treated 7075 Aluminum Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Bacci%20Fernandes">Bruno Bacci Fernandes</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephan%20M%C3%A4ndl"> Stephan Mändl</a>, <a href="https://publications.waset.org/abstracts/search?q=Ata%C3%ADde%20Ribeiro%20da%20Silva%20Junior"> Ataíde Ribeiro da Silva Junior</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Osvaldo%20Rossi"> José Osvaldo Rossi</a>, <a href="https://publications.waset.org/abstracts/search?q=M%C3%A1rio%20Ueda"> Mário Ueda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nitrogen implantation in aluminum and its alloys is acquainted for the difficulties in obtaining modified layers deeper than 200 nm. The present work addresses a new method to overcome such a problem; although, the coating with nitrogen and oxygen obtained by plasma immersion ion implantation (PIII) into a 7075 aluminum alloy surface was too shallow. This alloy is commonly used for structural parts in aerospace applications. Such a layer was characterized by secondary ion mass spectroscopy, electron microscopy, and nanoindentation experiments reciprocating wear tests. From the results, one can assume that the wear of this aluminum alloy starts presenting severe abrasive wear followed by an additional adhesive mechanism. PIII produced a slight difference, as shown in all characterizations carried out in this work. The results shown here can be used as the scientific basis for further nitrogen PIII experiments in aluminum alloys which have the goal to produce thicker modified layers or to improve their surface properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminum%20alloys" title="aluminum alloys">aluminum alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20immersion%20ion%20implantation" title=" plasma immersion ion implantation"> plasma immersion ion implantation</a>, <a href="https://publications.waset.org/abstracts/search?q=tribological%20properties" title=" tribological properties"> tribological properties</a>, <a href="https://publications.waset.org/abstracts/search?q=hardness" title=" hardness"> hardness</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofatigue" title=" nanofatigue"> nanofatigue</a> </p> <a href="https://publications.waset.org/abstracts/57186/nanocharacterization-of-piii-treated-7075-aluminum-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57186.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">339</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">32</span> Prediction of Fracture Aperture in Fragmented Rocks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Agheshlui">Hossein Agheshlui</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephan%20Matthai"> Stephan Matthai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In fractured rock masses open fractures tend to act as the main pathways of fluid flow. The permeability of a rock fracture depends on its aperture. The change of aperture with stress can cause a many-orders-of-magnitude change in the hydraulic conductivity at moderate compressive stress levels. In this study, the change of aperture in fragmented rocks is investigated using finite element analysis. A full 3D mechanical model of a simplified version of an outcrop analog is created and studied. A constant initial aperture value is applied to all fractures. Different far field stresses are applied and the change of aperture is monitored considering the block to block interaction. The fragmented rock layer is assumed to be sandwiched between softer layers. Frictional contact forces are defined at the layer boundaries as well as among contacting rock blocks. For a given in situ stress, the blocks slide and contact each other, resulting in new aperture distributions. A map of changed aperture is produced after applying the in situ stress and compared to the initial apertures. Subsequently, the permeability of the system before and after the stress application is compared. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fractured%20rocks" title="fractured rocks">fractured rocks</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20model" title=" mechanical model"> mechanical model</a>, <a href="https://publications.waset.org/abstracts/search?q=aperture%20change%20due%20to%20stress" title=" aperture change due to stress"> aperture change due to stress</a>, <a href="https://publications.waset.org/abstracts/search?q=frictional%20interface" title=" frictional interface"> frictional interface</a> </p> <a href="https://publications.waset.org/abstracts/71076/prediction-of-fracture-aperture-in-fragmented-rocks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71076.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">417</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> Statistical Variability of Soil Parameters within the Copper Belt Region of the Democratic Republic of the Congo</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stephan%20P.%20Barkhuizen">Stephan P.

The shear strength and saturated permeability of soil and tailings samples obtained from 14 sites located in the copper belt in the Democratic Republic of the Congo have been tested at six commercial soil laboratories in South Africa. This study compiles a database of the test results proved by the soil laboratories. The samples have been categorised into clay, silt, and sand, based on the Unified Soil Classification System, with tailings kept separate. The effective friction angle (Φ’) and cohesion (c’) were interpreted from the stress paths, in s’:t space, obtained from triaxial tests. The minimum, lower quartile, median, upper quartile, and maximum values for Φ’,c’, and saturated hydraulic conductivity (k) have been determined for the soil sample. The objective is to provide statistics of the measured values of the engineering properties for the TSF borrow material, foundation soils and tailings of this region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Democratic%20Republic%20of%20the%20Congo" title="Democratic Republic of the Congo">Democratic Republic of the Congo</a>, <a href="https://publications.waset.org/abstracts/search?q=laboratory%20test%20work" title=" laboratory test work"> laboratory test work</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20engineering%20parameter%20variation" title=" soil engineering parameter variation"> soil engineering parameter variation</a>, <a href="https://publications.waset.org/abstracts/search?q=tailings%20storage%20facilities" title=" tailings storage facilities"> tailings storage facilities</a> </p> <a href="https://publications.waset.org/abstracts/182795/statistical-variability-of-soil-parameters-within-the-copper-belt-region-of-the-democratic-republic-of-the-congo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182795.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">64</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> Operational Excellence Performance in Pharmaceutical Quality Control Labs: An Empirical Investigation of the Effectiveness and Efficiency Relation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stephan%20Koehler">Stephan Koehler</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Friedli"> Thomas Friedli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Performance measurement has evolved over time from a unidimensional short-term efficiency focused approach into a balanced multidimensional approach. Today, integrated performance measurement frameworks are often used to avoid local optimization and to encourage continuous improvement of an organization. In literature, the multidimensional characteristic of performance measurement is often described by competitive priorities. At the same time, on the highest abstraction level an effectiveness and efficiency dimension of performance measurement can be distinguished. This paper aims at a better understanding of the composition of effectiveness and efficiency and their relation in pharmaceutical quality control labs. The research comprises a lab-specific operationalization of effectiveness and efficiency and examines how the two dimensions are interlinked. The basis for the analysis represents a database of the University of St. Gallen including a divers set of 40 different pharmaceutical quality control labs. The research provides empirical evidence that labs with a high effectiveness also accompany a high efficiency. Lab effectiveness explains 29.5 % of the variance in lab efficiency. In addition, labs with an above median operational excellence performance have a statistically significantly higher lab effectiveness and lab efficiency compared to the below median performing labs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=empirical%20study" title="empirical study">empirical study</a>, <a href="https://publications.waset.org/abstracts/search?q=operational%20excellence" title=" operational excellence"> operational excellence</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20measurement" title=" performance measurement"> performance measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmaceutical%20quality%20control%20lab" title=" pharmaceutical quality control lab"> pharmaceutical quality control lab</a> </p> <a href="https://publications.waset.org/abstracts/89164/operational-excellence-performance-in-pharmaceutical-quality-control-labs-an-empirical-investigation-of-the-effectiveness-and-efficiency-relation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89164.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">161</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> Metagenomics Composition During and After Wet Deposition and the Presence of Airborne Microplastics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yee%20Hui%20Lim">Yee Hui Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Elena%20Gusareva"> Elena Gusareva</a>, <a href="https://publications.waset.org/abstracts/search?q=Irvan%20Luhung"> Irvan Luhung</a>, <a href="https://publications.waset.org/abstracts/search?q=Yulia%20Frank"> Yulia Frank</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephan%20Christoph%20Schuster"> Stephan Christoph Schuster</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Environmental pollution from microplastics (MPs) is an emerging concern worldwide. While the presence of microplastics has been well established in the marine and terrestrial environments, the prevalence of microplastics in the atmosphere is still poorly understood. Wet depositions such as rain or snow scavenge impurities from the atmosphere as it falls to the ground. These wet depositions serve as a useful tool in the removal of airborne particles that are suspended in the air. Therefore, the aim of this study is to investigate the presence of atmospheric microplastics and fibres through the analysis of air, rainwater and snow samples. Air samples were collected with filter-based air samplers from outdoor locations in Singapore. The sampling campaigns were conducted during and after each rain event. Rainwater samples from Singapore and Siberia were collected as well. Snow samples were also collected from Siberia as part of the ongoing study. Genomic DNA was then extracted from the samples and sequenced with shotgun metagenomics approach. qPCR analysis was conducted to quantify the total bacteria and fungi in the air, rainwater and snow samples. The results compared the bioaerosol profiles of all the samples. To observe the presence of microplastics, scanning electron microscope (SEM) was used. From the preliminary results, microplastics were detected. It can be concluded that there is a significant amount of atmospheric microplastics present, and its occurrence should be investigated in greater detail. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atmospheric%20microplastics" title="atmospheric microplastics">atmospheric microplastics</a>, <a href="https://publications.waset.org/abstracts/search?q=metagenomics" title=" metagenomics"> metagenomics</a>, <a href="https://publications.waset.org/abstracts/search?q=scanning%20electron%20microscope" title=" scanning electron microscope"> scanning electron microscope</a>, <a href="https://publications.waset.org/abstracts/search?q=wet%20deposition" title=" wet deposition"> wet deposition</a> </p> <a href="https://publications.waset.org/abstracts/153093/metagenomics-composition-during-and-after-wet-deposition-and-the-presence-of-airborne-microplastics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153093.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">86</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> The Dynamics of a 3D Vibrating and Rotating Disc Gyroscope </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Getachew%20T.%20Sedebo">Getachew T.

Due to the Bryan's effect, the vibrating pattern of the disc becomes sensitive to the axial component of inertial rotation of the disc. Rotation of the vibrating pattern relative to the disc is proportional to the inertial angular rate and is measured by sensors. In the present paper, the authors investigate a possibility of making a 3D sensor on the basis of both in-plane and bending vibrations of the disc resonator. We derive equations of motion for the disc vibratory gyroscope, where both in-plane and bending vibrations are considered. Hamiltonian variational principle is used in setting up equations of motion and the corresponding boundary conditions. The theory of thin shells with the linear elasticity principles is used in formulating the problem and also the disc is assumed to be isotropic and obeys Hooke's Law. The governing equation for a specific mode is converted to an ODE to determine the eigenfunction. The resulting ODE has exact solution as a linear combination of Bessel and Neumann functions. We demonstrate how to obtain an explicit solution and hence the eigenvalues and corresponding eigenfunctions for annular disc with fixed inner boundary and free outer boundary. Finally, the characteristics equations are obtained and the corresponding eigenvalues are calculated. The eigenvalues are used for the calculation of tuning conditions of the 3D disc vibratory gyroscope. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bryan%E2%80%99s%20effect" title="Bryan’s effect">Bryan’s effect</a>, <a href="https://publications.waset.org/abstracts/search?q=bending%20vibrations" title=" bending vibrations"> bending vibrations</a>, <a href="https://publications.waset.org/abstracts/search?q=disc%20gyroscope" title=" disc gyroscope"> disc gyroscope</a>, <a href="https://publications.waset.org/abstracts/search?q=eigenfunctions" title=" eigenfunctions"> eigenfunctions</a>, <a href="https://publications.waset.org/abstracts/search?q=eigenvalues" title=" eigenvalues"> eigenvalues</a>, <a href="https://publications.waset.org/abstracts/search?q=tuning%20conditions" title=" tuning conditions"> tuning conditions</a> </p> <a href="https://publications.waset.org/abstracts/52286/the-dynamics-of-a-3d-vibrating-and-rotating-disc-gyroscope" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52286.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">323</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">27</span> Contemporary Army Prints for Women’s Wear Kurti</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shaleni%20Bajpai">Shaleni Bajpai</a>, <a href="https://publications.waset.org/abstracts/search?q=Nancy%20Stephan"> Nancy Stephan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Various designs of women’s kurtis with different styles, motifs and prints were available in market but none of the kurtis was found in army print. Mostly army prints are used for men’s wear like jackets, trousers, caps, bags. The main colours available in military prints were beige, parrot green, red, dark blue, light blue, orange, bottle green, pink and the original military green colour. As the original camouflage is banned in civil wears so the different variety and colours were used in this study to popularize army prints in women’s wear. The aim of this project was to construct different styles of women kurti’s with various colours of different military prints. Mood board, inspiration and colour board was prepared to design the kurtis. The fabric used for construction was army printed poplin and crepe. The designing and construction of kurti’s were divided into two categories such as - casual and party wear. Casual wear had simple silhouette like a-line, high-low and waist coat style whereas party wear included princess line, panelled and bandhani style. Structured questionnaire was prepared to assess the acceptance of newly designed kurtis with respect to colour combination, overall appearance and cost. Purposively sampling method was adopted for selection of respondents. Opinion was taken from 100 women of various age groups. The result and analysis was presented through graph and percentage. Kurtis in army print of both the categories were appreciated by the respondents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=army" title="army">army</a>, <a href="https://publications.waset.org/abstracts/search?q=kurti" title=" kurti"> kurti</a>, <a href="https://publications.waset.org/abstracts/search?q=casual%20wear" title=" casual wear"> casual wear</a>, <a href="https://publications.waset.org/abstracts/search?q=party%20wear" title=" party wear"> party wear</a> </p> <a href="https://publications.waset.org/abstracts/52909/contemporary-army-prints-for-womens-wear-kurti" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52909.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">302</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> Synthetic Access to Complex Metal Carbonates and Hydroxycarbonates via Sol-Gel Chemistry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Schirin%20Hanf">Schirin Hanf</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Lizandara-Pueyo"> Carlos Lizandara-Pueyo</a>, <a href="https://publications.waset.org/abstracts/search?q=Timmo%20P.%20Emmert"> Timmo P.

Schunk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Metal alkoxides are very versatile precursors for a broad array of complex functional materials. However, metal alkoxides, especially transition metal alkoxides, tend to form oligomeric structures due to the very strong M–O–M binding motif. This fact hinders their facile application in sol-gel-processes and complicates access to complex carbonate or oxidic compounds after hydrolysis of the precursors. Therefore, the development of a synthetic alternative with the aim to grant access to carbonates and hydroxycarbonates from simple metal alkoxide precursors via hydrolysis is key to this project. Our approach involves the reaction of metal alkoxides with unsaturated isoelectronic molecules, such as carbon dioxide. Subsequently, a stoichiometric insertion of the CO₂ into the alkoxide M–O bond takes place and leads to the formation of soluble metal alkyl carbonates. This strategy is a very elegant approach to solubilize metal alkoxide precursors to make them accessible for sol-gel chemistry. After hydrolysis of the metal alkyl carbonates, crystalline metal carbonates, and hydroxycarbonates can be obtained, which were then utilized for the synthesis of Cu/Zn based bulk catalysts for methanol synthesis. Using these catalysts, a comparable catalytic activity to commercially available MeOH catalysts could be reached. Based on these results, a complement for traditional precipitation techniques, which are usually utilized for the synthesis of bulk methanol catalysts, have been found based on an alternative solubilization strategy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metal%20alkoxides" title="metal alkoxides">metal alkoxides</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20carbonates" title=" metal carbonates"> metal carbonates</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20hydroxycarbonates" title=" metal hydroxycarbonates"> metal hydroxycarbonates</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20insertion" title=" CO₂ insertion"> CO₂ insertion</a>, <a href="https://publications.waset.org/abstracts/search?q=solubilization" title=" solubilization"> solubilization</a> </p> <a href="https://publications.waset.org/abstracts/135815/synthetic-access-to-complex-metal-carbonates-and-hydroxycarbonates-via-sol-gel-chemistry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135815.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">187</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> Extracellular Enzymes as Promising Soil Health Indicators: Assessing Response to Different Land Uses Using Long-Term Experiments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Munisath%20Khandoker">Munisath Khandoker</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephan%20Haefele"> Stephan Haefele</a>, <a href="https://publications.waset.org/abstracts/search?q=Andy%20Gregory"> Andy Gregory</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Extracellular enzymes play a key role in soil organic carbon (SOC) decomposition and nutrient cycling and are known indicators for soil health; however, it is not understood how these enzymes respond to different land uses and their relationships to other soil properties have not been extensively reviewed. The relationships among the activities of three soil enzymes: β-glucosaminidase (NAG), phosphomonoesterase (PHO) and β-glucosidase (GLU), were examined. The impact of soil organic amendments, soil types and land management on soil enzyme activities were reviewed, and it was hypothesized that soils with increased SOC have increased enzyme activity. Long-term experiments at Rothamsted Research Woburn and Harpenden sites in the UK were used to evaluate how different management practices affect enzyme activity involved in carbon (C) and nitrogen (N) cycling in the soil. Samples were collected from soils with different organic treatments such as straw, farmyard manure (FYM), compost additions, cover crops and permanent grass cover to assess whether SOC can be linked with increased levels of enzymatic activity and what influence, if any, enzymatic activity has on total C and N in the soil. Investigating the interactions of important enzymes with soil characteristics and SOC can help to better understand the health of soils. Studies on long-term experiments with known histories and large datasets can better help with this. SOC tends to decrease during land use changes from natural ecosystems to agricultural systems; therefore, it is imperative that agricultural lands find ways to increase and/or maintain SOC in the soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biological%20soil%20health%20indicators" title="biological soil health indicators">biological soil health indicators</a>, <a href="https://publications.waset.org/abstracts/search?q=extracellular%20enzymes" title=" extracellular enzymes"> extracellular enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20health" title=" soil health"> soil health</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil"> soil</a>, <a href="https://publications.waset.org/abstracts/search?q=microbiology" title=" microbiology"> microbiology</a> </p> <a href="https://publications.waset.org/abstracts/172000/extracellular-enzymes-as-promising-soil-health-indicators-assessing-response-to-different-land-uses-using-long-term-experiments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172000.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">73</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> Reorientation of Anisotropic Particles in Free Liquid Microjets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mathias%20Schlenk">Mathias Schlenk</a>, <a href="https://publications.waset.org/abstracts/search?q=Susanne%20Seibt"> Susanne Seibt</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabine%20Rosenfeldt"> Sabine Rosenfeldt</a>, <a href="https://publications.waset.org/abstracts/search?q=Josef%20Breu"> Josef Breu</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephan%20Foerster"> Stephan Foerster</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Thin liquid jets on micrometer scale play an important role in processing such as in fiber fabrication, inkjet printing, but also for sample delivery in modern synchrotron X-ray devices. In all these cases the liquid jets contain solvents and dissolved materials such as polymers, nanoparticles, fibers pigments or proteins. As liquid flow in liquid jets differs significantly from flow in capillaries and microchannels, particle localization and orientation will also be different. This is of critical importance for applications, which depend on well-defined homogeneous particle and fiber distribution and orientation in liquid jets. Investigations of particle orientation in liquid microjets of diluted solutions have been rare, despite their importance. With the arise of micro-focused X-ray beams it has become possible to scan across samples with micrometer resolution to locally analyse structure and orientation of the samples. In the present work, we used this method to scan across liquid microjets to determine the local distribution and orientation of anisotropic particles. The compromise wormlike block copolymer micelles as an example of long flexible fibrous structures, hectorite materials as a model of extended nanosheet structures, and gold nanorods as an illustration of short stiff cylinders to comprise all relevant anisotropic geometries. We find that due to the different velocity profile in the liquid jet, which resembles plug flow, the orientation of the particles which was generated in the capillary is lost or changed into non-oriented or bi-axially orientations depending on the geometrical shape of the particle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anisotropic%20particles" title="anisotropic particles">anisotropic particles</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20microjets" title=" liquid microjets"> liquid microjets</a>, <a href="https://publications.waset.org/abstracts/search?q=reorientation" title=" reorientation"> reorientation</a>, <a href="https://publications.waset.org/abstracts/search?q=SAXS" title=" SAXS"> SAXS</a> </p> <a href="https://publications.waset.org/abstracts/64389/reorientation-of-anisotropic-particles-in-free-liquid-microjets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64389.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">339</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> A Randomized Controlled Intervention Study of the Effect of Music Training on Mathematical and Working Memory Performances</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ingo%20Roden">Ingo Roden</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefana%20Lupu"> Stefana Lupu</a>, <a href="https://publications.waset.org/abstracts/search?q=Mara%20Krone"> Mara Krone</a>, <a href="https://publications.waset.org/abstracts/search?q=Jasmin%20Chantah"> Jasmin Chantah</a>, <a href="https://publications.waset.org/abstracts/search?q=Gunter%20Kreutz"> Gunter Kreutz</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephan%20Bongard"> Stephan Bongard</a>, <a href="https://publications.waset.org/abstracts/search?q=Dietmar%20Grube"> Dietmar Grube</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present experimental study examined the effects of music and math training on mathematical skills and visuospatial working memory capacity in kindergarten children. For this purpose, N = 54 children (mean age: 5.46 years; SD = .29) were randomly assigned to three groups. Children in the music group (n = 18) received weekly sessions of 60 min music training over a period of eight weeks, whereas children in the math group (n = 18) received the same amount of training focusing on mathematical basic skills, such as numeracy skills, quantity comparison, and counting objectives. The third group of children (n = 18) served as waiting controls. The groups were matched for sex, age, IQ and previous music experiences at baseline. Pre-Post intervention measurements revealed a significant interaction effect of group x time, showing that children in both music and math groups significantly improved their early numeracy skills, whereas children in the control group did not. No significant differences between groups were observed for the visuospatial working memory performances. These results confirm and extend previous findings on transfer effects of music training on mathematical abilities and visuospatial working memory capacity. They show that music and math interventions are similarly effective to enhance children’s mathematical skills. More research is necessary to establish, whether cognitive transfer effects arising from music interventions might facilitate children’s transition from kindergarten to first-grade. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=music%20training" title="music training">music training</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20skills" title=" mathematical skills"> mathematical skills</a>, <a href="https://publications.waset.org/abstracts/search?q=working%20memory" title=" working memory"> working memory</a>, <a href="https://publications.waset.org/abstracts/search?q=transfer" title=" transfer"> transfer</a> </p> <a href="https://publications.waset.org/abstracts/98097/a-randomized-controlled-intervention-study-of-the-effect-of-music-training-on-mathematical-and-working-memory-performances" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98097.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">272</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> Effects of Music Training on Social-Emotional Development and Basic Musical Skills: Findings from a Longitudinal Study with German and Migrant Children</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stefana%20Francisca%20Lupu">Stefana Francisca Lupu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jasmin%20Chantah"> Jasmin Chantah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mara%20Krone"> Mara Krone</a>, <a href="https://publications.waset.org/abstracts/search?q=Ingo%20Roden"> Ingo Roden</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephan%20Bongard"> Stephan Bongard</a>, <a href="https://publications.waset.org/abstracts/search?q=Gunter%20Kreutz"> Gunter Kreutz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Long-term music interventions could enhance both musical and nonmusical skills.

Due to the uncertainty and risks involved in this complex decision making process, the need arises for well-structured support activities. A method that considers cost and the long-term added value is the cost-benefit effectiveness estimation. One of those methods is the “profitability estimation focused on benefits – PEFB”-method developed at the Institute of Management Cybernetics at RWTH Aachen University. The method copes with the challenges associated with strategic investment decisions by integrating long-term non-monetary aspects whilst also mapping the chronological sequence of an investment within the organization’s target system. Thus, this method is characterized as a holistic approach for the evaluation of costs and benefits of an investment. This participation-oriented method was applied to business environments in many workshops. The results of the workshops are a library of more than 96 cost aspects, as well as 122 benefit aspects. These aspects are preprocessed and comparatively analyzed with regards to their alignment to a series of risk levels. For the first time, an accumulation and a distribution of cost and benefit aspects regarding their impact and probability of occurrence are given. The results give evidence that the PEFB-method combines precise measures of financial accounting with the incorporation of benefits. Finally, the results constitute the basics for using information technology and data science for decision support when applying within the PEFB-method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cost-benefit%20analysis" title="cost-benefit analysis">cost-benefit analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-criteria%20decision" title=" multi-criteria decision"> multi-criteria decision</a>, <a href="https://publications.waset.org/abstracts/search?q=profitability%20estimation%20focused%20on%20benefits" title=" profitability estimation focused on benefits"> profitability estimation focused on benefits</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20and%20uncertainty%20analysis" title=" risk and uncertainty analysis"> risk and uncertainty analysis</a> </p> <a href="https://publications.waset.org/abstracts/34645/long-term-examination-of-the-profitability-estimation-focused-on-benefits" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34645.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">445</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> A Comparative Study on Primary Productivity in Fish Cage Culture Unit and Fish Pond in Relation to Different Level of Water Depth</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pawan%20Kumar%20Sharma">Pawan Kumar Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=J.%20Stephan%20Sampath%20Kumar"> J.

The present study was carried out to understand the relationship between productivity in the cages and water depth. The experiment was conducted in the fish cages installed in the pond at the Directorate of Sustainable Aquaculture, Thanjavur, Tamil Nadu Dr. J. Jayalalithaa Fisheries University, Tamil Nadu (10° 47' 13.1964'' N; 79° 8' 16.1700''E). Primary productivity was estimated by light and dark bottle method. The measurement of primary productivity was done at different depths viz., 20 cm, 40 cm, and 60 cm. Six Biological Oxygen Demand bottles of 300 ml capacity were collected and tagged. The productivity was obtained in mg O2/l/hr. The maximum dissolved oxygen level at 20 cm depth was observed 5.62 ± 0.22 mg/l/hr in the light bottle in pond water while the minimum dissolved oxygen level at 20 cm depth in a cage was observed 3.62 ± 0.18 mg/l/hr in dark bottle. In the same way, the maximum and minimum value of dissolved oxygen was observed at 40, and 60 cm depth and results were compared. A slight change in pH was observed in the cage and pond. The maximum gross primary productivity observed was 1.97 mg/l/hr in pond at 20 cm depth while minimum gross primary productivity observed was 0.82±0.16 mg/l/hr in a cage at 60 cm depth. The community respiration was also variable with the depth in both cage and pond. Maximum community respiration was found 1.50±0.19 mg/l/hr in pond at 20 cm depth. A strong positive linear relationship was observed between primary productivity and fish yields in ponds. The pond primary productivity can contribute substantially to the nutrition of farm-raised aquaculture species, including shrimp. The growth of phytoplankton’s is dependent on the sun light, availability of primary nutrients (N, P, and K) in the water body and transparency, so to increase the primary productivity fertilization through organic manure may be done that will clean to the pond environment also. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cage%20aquaculture" title="cage aquaculture">cage aquaculture</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20depth" title=" water depth"> water depth</a>, <a href="https://publications.waset.org/abstracts/search?q=net%20primary%20productivity" title=" net primary productivity"> net primary productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=gross%20primary%20productivity" title=" gross primary productivity"> gross primary productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=community%20respiration" title=" community respiration"> community respiration</a> </p> <a href="https://publications.waset.org/abstracts/119278/a-comparative-study-on-primary-productivity-in-fish-cage-culture-unit-and-fish-pond-in-relation-to-different-level-of-water-depth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119278.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">19</span> Biogas from Cover Crops and Field Residues: Effects on Soil, Water, Climate and Ecological Footprint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manfred%20Szerencsits">Manfred Szerencsits</a>, <a href="https://publications.waset.org/abstracts/search?q=Christine%20Weinberger"> Christine Weinberger</a>, <a href="https://publications.waset.org/abstracts/search?q=Maximilian%20Kuderna"> Maximilian Kuderna</a>, <a href="https://publications.waset.org/abstracts/search?q=Franz%20Feichtinger"> Franz Feichtinger</a>, <a href="https://publications.waset.org/abstracts/search?q=Eva%20Erhart"> Eva Erhart</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephan%20Maier"> Stephan Maier</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cover or catch crops have beneficial effects for soil, water, erosion, etc. If harvested, they also provide feedstock for biogas without competition for arable land in regions, where only one main crop can be produced per year. On average gross energy yields of approx. 1300 m³ methane (CH<sub>4</sub>) ha<sup>-1</sup> can be expected from 4.5 tonnes (t) of cover crop dry matter (DM) in Austria. Considering the total energy invested from cultivation to compression for biofuel use a net energy yield of about 1000 m³ CH<sub>4</sub> ha<sup>-1</sup> is remaining. With the straw of grain maize or Corn Cob Mix (CCM) similar energy yields can be achieved. In comparison to catch crops remaining on the field as green manure or to complete fallow between main crops the effects on soil, water and climate can be improved if cover crops are harvested without soil compaction and digestate is returned to the field in an amount equivalent to cover crop removal. In this way, the risk of nitrate leaching can be reduced approx. by 25% in comparison to full fallow. The risk of nitrous oxide emissions may be reduced up to 50% by contrast with cover crops serving as green manure. The effects on humus content and erosion are similar or better than those of cover crops used as green manure when the same amount of biomass was produced. With higher biomass production the positive effects increase even if cover crops are harvested and the only digestate is brought back to the fields. The ecological footprint of arable farming can be reduced by approx. 50% considering the substitution of natural gas with CH<sub>4</sub> produced from cover crops. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biogas" title="biogas">biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=cover%20crops" title=" cover crops"> cover crops</a>, <a href="https://publications.waset.org/abstracts/search?q=catch%20crops" title=" catch crops"> catch crops</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20use%20competition" title=" land use competition"> land use competition</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20agriculture" title=" sustainable agriculture"> sustainable agriculture</a> </p> <a href="https://publications.waset.org/abstracts/20329/biogas-from-cover-crops-and-field-residues-effects-on-soil-water-climate-and-ecological-footprint" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20329.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">542</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> An Energy Transfer Fluorescent Probe System for Glucose Sensor at Biomimetic Membrane Surface</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hoa%20Thi%20Hoang">Hoa Thi Hoang</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephan%20Sass"> Stephan Sass</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20U.%20Kumke"> Michael U.

For glucose sensor using conA, either fluoresence based techniques with intensity based or lifetime based are used. In this research, liposomes made from phospholipids were used as a biomimetic membrane system. In a first step, novel building blocks containing perylene labeled glucose units were added to the system and used to decorate the surface of the liposomes. Upon the binding between rhodamine labeled con A to the glucose units at the biomimetic membrane surface, a Förster resonance energy transfer system can be formed which combines unique fluorescence properties of perylene (e.g., high fluorescence quantum yield, no triplet formation) and its high hydrophobicity for efficient anchoring in membranes to form a novel probe for the investigation of sugar-driven binding reactions at biomimetic surfaces. Two glucose-labeled perylene derivatives were synthesized with different spacer length between the perylene and glucose unit in order to probe the binding of conA. The binding interaction was fully characterized by using high-end fluorescence techniques. Steady-state and time-resolved fluorescence techniques (e.g., fluorescence depolarization) in combination with single-molecule fluorescence spectroscopy techniques (fluorescence correlation spectroscopy, FCS) were used to monitor the interaction with conA. Base on the fluorescence depolarization, the rotational correlation times and the alteration in the diffusion coefficient (determined by FCS) the binding of the conA to the liposomes carrying the probe was studied. Moreover, single pair FRET experiments using pulsed interleaved excitation are used to characterize in detail the binding of conA to the liposome on a single molecule level avoiding averaging out effects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concanavalin%20A" title="concanavalin A">concanavalin A</a>, <a href="https://publications.waset.org/abstracts/search?q=FRET" title=" FRET"> FRET</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor" title=" sensor"> sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=biomimetic%20membrane" title=" biomimetic membrane"> biomimetic membrane</a> </p> <a href="https://publications.waset.org/abstracts/50468/an-energy-transfer-fluorescent-probe-system-for-glucose-sensor-at-biomimetic-membrane-surface" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50468.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">307</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> Introducing, Testing, and Evaluating a Unified JavaScript Framework for Professional Online Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Caspar%20Goeke">Caspar Goeke</a>, <a href="https://publications.waset.org/abstracts/search?q=Holger%20Finger"> Holger Finger</a>, <a href="https://publications.waset.org/abstracts/search?q=Dorena%20Diekamp"> Dorena Diekamp</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20K%C3%B6nig"> Peter König</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Online-based research has recently gained increasing attention from various fields of research in the cognitive sciences. Technological advances in the form of online crowdsourcing (Amazon Mechanical Turk), open data repositories (Open Science Framework), and online analysis (Ipython notebook) offer rich possibilities to improve, validate, and speed up research. However, until today there is no cross-platform integration of these subsystems. Furthermore, implementation of online studies still suffers from the complex implementation (server infrastructure, database programming, security considerations etc.). Here we propose and test a new JavaScript framework that enables researchers to conduct any kind of behavioral research in the browser without the need to program a single line of code. In particular our framework offers the possibility to manipulate and combine the experimental stimuli via a graphical editor, directly in the browser. Moreover, we included an action-event system that can be used to handle user interactions, interactively change stimuli properties or store participants’ responses. Besides traditional recordings such as reaction time, mouse and keyboard presses, the tool offers webcam based eye and face-tracking. On top of these features our framework also takes care about the participant recruitment, via crowdsourcing platforms such as Amazon Mechanical Turk. Furthermore, the build in functionality of google translate will ensure automatic text translations of the experimental content. Thereby, thousands of participants from different cultures and nationalities can be recruited literally within hours. Finally, the recorded data can be visualized and cleaned online, and then exported into the desired formats (csv, xls, sav, mat) for statistical analysis. Alternatively, the data can also be analyzed online within our framework using the integrated Ipython notebook. The framework was designed such that studies can be used interchangeably between researchers. This will support not only the idea of open data repositories but also constitutes the possibility to share and reuse the experimental designs and analyses such that the validity of the paradigms will be improved. Particularly, sharing and integrating the experimental designs and analysis will lead to an increased consistency of experimental paradigms. To demonstrate the functionality of the framework we present the results of a pilot study in the field of spatial navigation that was conducted using the framework. Specifically, we recruited over 2000 subjects with various cultural backgrounds and consequently analyzed performance difference in dependence on the factors culture, gender and age. Overall, our results demonstrate a strong influence of cultural factors in spatial cognition. Such an influence has not yet been reported before and would not have been possible to show without the massive amount of data collected via our framework. In fact, these findings shed new lights on cultural differences in spatial navigation. As a consequence we conclude that our new framework constitutes a wide range of advantages for online research and a methodological innovation, by which new insights can be revealed on the basis of massive data collection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cultural%20differences" title="cultural differences">cultural differences</a>, <a href="https://publications.waset.org/abstracts/search?q=crowdsourcing" title=" crowdsourcing"> crowdsourcing</a>, <a href="https://publications.waset.org/abstracts/search?q=JavaScript%20framework" title=" JavaScript framework"> JavaScript framework</a>, <a href="https://publications.waset.org/abstracts/search?q=methodological%20innovation" title=" methodological innovation"> methodological innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20data%20collection" title=" online data collection"> online data collection</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20study" title=" online study"> online study</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20cognition" title=" spatial cognition"> spatial cognition</a> </p> <a href="https://publications.waset.org/abstracts/68298/introducing-testing-and-evaluating-a-unified-javascript-framework-for-professional-online-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68298.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">257</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> Racism as a Biopolitical Bordering: Experiences of the Lhotshampa People Displaced from Bhutan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karun%20Karki">Karun Karki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Lhotshampa are Bhutanese people of Nepali origin who have been in Bhutan since the early 1600s. A significant number of these people migrated to Bhutan in the nineteenth century. The 1958 Nationality Law of Bhutan granted citizenship to many Lhotshampa people; however, in the late 1970s, the government of Bhutan introduced a series of laws and policies intended for the socio-political and cultural exclusion of the Lhotshampa due to their ancestry. These exclusionary policies and ethnic and racial injustices not only removed the rights and citizenship of the Lhotshampa but also forcibly displaced thousands of families with no choice but to seek refuge in Nepal. In this context, racism becomes a biopolitical tool designed to govern and regulate populations in a way that determines who may live and who must die. The governance and the management of the population, what Stephan Scheel terms as biopolitical bordering, depends on boundaries between residents and non-residents, citizens and non-citizens, and emigrants and immigrants. Drawing on Foucault’s biopolitics and Mbembe’s necropolitics, this paper argues that the concept of racism should be examined within the context of political discourses because it is intertwined with the colonial project, enslavement, and diaspora. This paper critically explores ethnic and racial injustices the Lhotshampa people experienced and the ways in which they negotiated and resisted such injustices in their resettlement processes, including before displacement, in refugee camps, and after the third-country resettlement. Critical examination of these issues helps shed light on the notion of racial difference that justifies dehumanization, discrimination, and racist attitudes against the Lhotshampa people. The study's findings are critical in promoting human rights, social justice, and the health and well-being of the Lhotshampa community in the context of trauma and stressors in their resettlement processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lhotshampa%20people" title="lhotshampa people">lhotshampa people</a>, <a href="https://publications.waset.org/abstracts/search?q=bhutanese%20refugees" title=" bhutanese refugees"> bhutanese refugees</a>, <a href="https://publications.waset.org/abstracts/search?q=racism" title=" racism"> racism</a>, <a href="https://publications.waset.org/abstracts/search?q=dehumanization" title=" dehumanization"> dehumanization</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20justice" title=" social justice"> social justice</a>, <a href="https://publications.waset.org/abstracts/search?q=biopower" title=" biopower"> biopower</a>, <a href="https://publications.waset.org/abstracts/search?q=necropower" title=" necropower"> necropower</a> </p> <a href="https://publications.waset.org/abstracts/181643/racism-as-a-biopolitical-bordering-experiences-of-the-lhotshampa-people-displaced-from-bhutan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181643.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">53</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> Demand-Oriented Supplier Integration in Agile New Product Development Projects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guenther%20Schuh">Guenther Schuh</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephan%20Schroeder"> Stephan Schroeder</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcel%20Faulhaber"> Marcel Faulhaber</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Companies are facing an increasing pressure to innovate faster, cheaper and more radical in last years, due to shrinking product lifecycles and higher volatility of markets and customer demands. Especially established companies struggle meeting those demands. Thus, many producing companies are adapting their development processes to address this increasing pressure. One approach taken by many companies is the use of agile, highly iterative development processes to reduce development times and costs as well as to increase the fulfilled customer requirements and the realized level of innovation. At the same time decreasing depths of added value and increasing focus on core competencies as well as a growing product complexity result in a high dependency on suppliers and external development partners during the product development. Thus, a successful introduction of agile development methods into the development of physical products requires also a successful integration of the necessary external partners and suppliers into the new processes and procedures and an adaption of the organizational interfaces to external partners according to the new circumstances and requirements of agile development processes. For an effective and efficient product development, the design of customer-supplier-relationships should be demand-oriented. A significant influence on the required design has the characteristics of the procurement object. Examples therefore are the complexity of technical interfaces between supply object and final product or the importance of the supplied component for the major product functionalities. Thus, this paper presents an approach to derive general requirements on the design of supplier integration according to the characteristics of supply objects. First, therefore the most relevant evaluation criteria and characteristics have been identified based on a thorough literature review. Subsequently the resulting requirements on the design of the supplier integration were derived depending on the different possible values of these criteria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=iterative%20development%20processes" title="iterative development processes">iterative development processes</a>, <a href="https://publications.waset.org/abstracts/search?q=agile%20new%20product%20development" title=" agile new product development"> agile new product development</a>, <a href="https://publications.waset.org/abstracts/search?q=procurement" title=" procurement"> procurement</a>, <a href="https://publications.waset.org/abstracts/search?q=supplier%20integration" title=" supplier integration"> supplier integration</a> </p> <a href="https://publications.waset.org/abstracts/94123/demand-oriented-supplier-integration-in-agile-new-product-development-projects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94123.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">172</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Defence Industry in the Political Economy of State and Business Relations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hatice%20Idil%20Gorgen">Hatice Idil Gorgen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Turkey has been investing in its national defence industrial base since the 1980s. State’s role in defence industry showed differences in Turkey. Parallel with this, ruling group’s attitude toward companies in defence sector varied. These changes in policies and behaviors of the state have occurred throughout such milestones as political and economic turmoil in domestic and international level. Hence, it is argued that state’s role, relations with private companies in defense sector and its policies towards the defense industry has shown differences due to the international system, political institutions, ideas and political coalitions in Turkey since the 1980s. Therefore, in order to see changes in the role of the state in defence sector, this paper aims to indicate first, history of state’s role in production and defence industry in the post-1980s era. Secondly, to comprehend the changes in the state’s role in defence industry, Stephan Haggard’s sources of policy change will be provided in the theoretical ground. Thirdly, state cooperated, and joint venture defence firms, state’s actions toward them will be observed. The remaining part will explore the underlying reasons for the changes in the role of the state in defence industry, and it implicitly or explicitly impacts on state business relations. Major findings illustrate that targeted idea of self-sufficient or autarky Turkey to attract domestic audience and to raise the prestige through defence system; ruling elites can regard defence industry and involved business groups as a mean for their ends. State dominant value, sensitive perception which has been ever since Ottoman Empire, prioritizes business groups in defence industry compared to others and push the ruling elites to pursue hard power in defence sectors. Through the globally structural transformation in defence industry, integration of Turkey to liberal bloc deepened and widened interdependence among states. Although it is a qualitative study, it involves the numerated data and descriptive statistics. Data will be collected by searching secondary sources from the literature, examining official documents of ministry of defence, and other appropriate ministries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=defense%20industry" title="defense industry">defense industry</a>, <a href="https://publications.waset.org/abstracts/search?q=state%20and%20business%20relations" title=" state and business relations"> state and business relations</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20private%20relations" title=" public private relations"> public private relations</a>, <a href="https://publications.waset.org/abstracts/search?q=arm%20industry" title=" arm industry"> arm industry</a> </p> <a href="https://publications.waset.org/abstracts/80519/defence-industry-in-the-political-economy-of-state-and-business-relations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80519.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">315</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> Cost Effective and Efficient Feeding: A Way Forward for Sustainable and Profitable Aquaculture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pawan%20Kumar%20Sharma">Pawan Kumar Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=J.%20Stephan%20Sampath%20Kumar"> J.

Apparently, excess dietary protein is undesirable, as it not only enhances the production cost but also leads to water quality deterioration. A field survey was conducted with aqua farmers of Kerala, India, a leading state in coastal aquaculture, to assess the role of protein component in feed that can be efficiently and effectively managed for sustainable aquaculture. The study showed an average feed amount of 13.55 ± 2.16 tonnes per hectare was being used by the farmers of Kerala. The average feed cost percentage of Rs. 57.76 ± 13.46 /kg was invested for an average protein level of 36.26 % ± 0.082 in the feed and Rs.78.95 ± 3.086 per kilogram of feed was being paid by the farmers. Study revealed that replacement of fish meal and fish oil within shrimp aquafeeds with alternative protein, and lipid sources can only be achieved if changes are made in the basic shrimp culturing practices, such as closed farming system through water recycling or zero-water exchange, and by maximizing in-situ, floc and natural food production within the culture system. The upshot of such production systems is that imports of high-quality feed ingredients and aqua feeds can eventually be eliminated, and the utilization of locally available feed ingredients from agricultural by-products can be greatly improved and maximized. The promotion of closed shrimp production systems would also greatly reduce water use and increase shrimp production per unit area but would necessitate the continuous provision of electricity for aeration during production. Alternative energy sources such as solar power might be used, and resource poor farming communities should also explore wind energy for use. The study concluded that farm made feed and closed farming systems are essential for the sustainability and profitability of the aquaculture industry. <p class="card-text"><strong>Keywords:</strong>
