The metal composition of the ISM enables us to study the cooling and heating processes that dominate the star formation rates in our Galaxy. The Chandra High Energy Transmission Grating (HETG) Spectrometer provides a unique opportunity to measure element dust compositions through X-ray edge absorption structure. We measure gas to dust optical depth ratios towards 9 bright Low-Mass X-ray Binaries (LMXBs) in the Galactic Bulge with the highest precision so far. Well calibrated and pile-up free optical depths are measured with the HETG spectrometer with respect to broadband hydrogen equivalent absorption in bright LMXBs: 4U 1636-53, Ser X-1, GX 3+1, 4U 1728-34, 4U 1705-44, GX 340+0, GX 13+1, GX 5-1, and GX 349+2. From the optical depths results, we deduce gas to dust ratios for various silicates in the ISM and present our results for the Si K edge in different lines of sight towards the Galactic Bulge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low-mass%20X-ray%20binaries" title="low-mass X-ray binaries">low-mass X-ray binaries</a>, <a href="https://publications.waset.org/abstracts/search?q=interstellar%20medium" title=" interstellar medium"> interstellar medium</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20to%20dust%20ratio" title=" gas to dust ratio"> gas to dust ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=spectrometer" title=" spectrometer"> spectrometer</a> </p> <a href="https://publications.waset.org/abstracts/144260/measure-the-gas-to-dust-ratio-towards-bright-sources-in-the-galactic-bulge" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144260.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">143</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> A Deep Learning Approach for the Predictive Quality of Directional Valves in the Hydraulic Final Test</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christian%20Neunzig">Christian Neunzig</a>, <a href="https://publications.waset.org/abstracts/search?q=Simon%20Fahle"> Simon Fahle</a>, <a href="https://publications.waset.org/abstracts/search?q=J%C3%BCrgen%20Schulz"> Jürgen Schulz</a>, <a href="https://publications.waset.org/abstracts/search?q=Matthias%20M%C3%B6ller"> Matthias Möller</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernd%20Kuhlenk%C3%B6tter"> Bernd Kuhlenkötter</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increasing use of deep learning applications in production is becoming a competitive advantage.

Different terminologies for the same research object may arise in different research communities. By this inconsistency, many synergistic effects get lost. Theories and models will be more understandable and reusable if a common terminology is applied. This paper examines the terminological (in) consistency for the research field of job-shop scheduling through a literature review. There is an enormous variety in the choice of terms and mathematical notation for the same concept. The comparability, reusability, and combinability of scheduling methods are unnecessarily hampered by the arbitrary use of homonyms and synonyms. The acceptance in the community of used variables and notation forms is shown by means of a compliance quotient. This is proven by the evaluation of 240 scientific publications on planning methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=job-shop%20scheduling" title="job-shop scheduling">job-shop scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=terminology" title=" terminology"> terminology</a>, <a href="https://publications.waset.org/abstracts/search?q=notation" title=" notation"> notation</a>, <a href="https://publications.waset.org/abstracts/search?q=standardization" title=" standardization"> standardization</a> </p> <a href="https://publications.waset.org/abstracts/150516/towards-a-standardization-in-scheduling-models-assessing-the-variety-of-homonyms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150516.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">109</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">44</span> An Axisymmetric Finite Element Method for Compressible Swirling Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raphael%20Zanella">Raphael Zanella</a>, <a href="https://publications.waset.org/abstracts/search?q=Todd%20A.%20Oliver"> Todd A.

We are interested in problems where the flow, while weakly dependent on the azimuthal coordinate, may have a strong azimuthal velocity component. We describe the approximation of the compressible Navier-Stokes equations with H1-conformal spaces of axisymmetric functions. The weak formulation is implemented in a C++ solver with explicit time marching. The code is first verified with a convergence test on a manufactured solution. The verification is completed by comparing the numerical and analytical solutions in a Poiseuille flow case and a Taylor-Couette flow case. The code is finally applied to the problem of a swirling subsonic air flow in a plasma torch geometry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axisymmetric%20problem" title="axisymmetric problem">axisymmetric problem</a>, <a href="https://publications.waset.org/abstracts/search?q=compressible%20Navier-Stokes%20equations" title=" compressible Navier-Stokes equations"> compressible Navier-Stokes equations</a>, <a href="https://publications.waset.org/abstracts/search?q=continuous%20finite%20elements" title=" continuous finite elements"> continuous finite elements</a>, <a href="https://publications.waset.org/abstracts/search?q=swirling%20flow" title=" swirling flow"> swirling flow</a> </p> <a href="https://publications.waset.org/abstracts/143638/an-axisymmetric-finite-element-method-for-compressible-swirling-flow" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143638.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">174</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> Friction Estimation and Compensation for Steering Angle Control for Highly Automated Driving</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcus%20Walter">Marcus Walter</a>, <a href="https://publications.waset.org/abstracts/search?q=Norbert%20Nitzsche"> Norbert Nitzsche</a>, <a href="https://publications.waset.org/abstracts/search?q=Dirk%20Odenthal"> Dirk Odenthal</a>, <a href="https://publications.waset.org/abstracts/search?q=Steffen%20M%C3%BCller"> Steffen Müller</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This contribution presents a friction estimator for industrial purposes which identifies Coulomb friction in a steering system. The estimator only needs a few, usually known, steering system parameters. Friction occurs on almost every mechanical system and has a negative influence on high-precision position control. This is demonstrated on a steering angle controller for highly automated driving. In this steering system the friction induces limit cycles which cause oscillating vehicle movement when the vehicle follows a given reference trajectory. When compensating the friction with the introduced estimator, limit cycles can be suppressed. This is demonstrated by measurements in a series vehicle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=friction%20estimation" title="friction estimation">friction estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20compensation" title=" friction compensation"> friction compensation</a>, <a href="https://publications.waset.org/abstracts/search?q=steering%20system" title=" steering system"> steering system</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20vehicle%20guidance" title=" lateral vehicle guidance"> lateral vehicle guidance</a> </p> <a href="https://publications.waset.org/abstracts/27641/friction-estimation-and-compensation-for-steering-angle-control-for-highly-automated-driving" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27641.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">515</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">42</span> Reclaiming the House with Use of Web 2.0 Tools: Democratic Candidates and Social Media during Midterm Elections in 2018</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Norbert%20Tomaszewski">Norbert Tomaszewski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Modern politicians tend to resign from the traditional media as Web 2.0 tools allow them to interact with a much bigger audience while spending less money on their campaign. Current studies on this subject prove that in order to win the elections, the candidate needs to show his personal side during the campaign to appeal to the voter as an average citizen. Because of that, the internet user may engage in the politician's campaign by spreading his message along with his followers. The aim of the study is to determine how did the Democratic candidates use the Web 2.0 tools during the 2018 midterm elections campaign and whether they managed to succeed. Taking into consideration the fact that the United States as a country, has always set important milestones for the political marketing as a field of science, the result of the research can set some examples on how to manage the modern internet campaign in less developed countries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=political%20campaign" title="political campaign">political campaign</a>, <a href="https://publications.waset.org/abstracts/search?q=midterm%20elections" title=" midterm elections"> midterm elections</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media" title=" social media"> social media</a>, <a href="https://publications.waset.org/abstracts/search?q=Web%202.0" title=" Web 2.0"> Web 2.0</a> </p> <a href="https://publications.waset.org/abstracts/98321/reclaiming-the-house-with-use-of-web-20-tools-democratic-candidates-and-social-media-during-midterm-elections-in-2018" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98321.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">149</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> Simulation-Based Unmanned Surface Vehicle Design Using PX4 and Robot Operating System With Kubernetes and Cloud-Native Tooling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Norbert%20Szulc">Norbert Szulc</a>, <a href="https://publications.waset.org/abstracts/search?q=Jakub%20Wilk"> Jakub Wilk</a>, <a href="https://publications.waset.org/abstracts/search?q=Franciszek%20G%C3%B3rski"> Franciszek Górski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an approach for simulating and testing robotic systems based on PX4, using a local Kubernetes cluster.

This study examines distinct AI acceptance among gastroenterologists with contrasting levels of seniority/experience when interacting with AI typologies. Data from 319 gastroenterologists show the presence of four distinct clusters of clinicians based on experience levels and perceived risk typologies. Analysis of cluster-based responses further revealed that acceptance of AI was not uniform. Our findings showed that clinician experience and risk perspective have an interactive role in influencing AI acceptance. Senior clinicians with low-risk perceptions were highly accepting of AI, but those with high-risk perceptions of AI were substantially less accepting. In contrast, junior clinicians were more inclined to embrace AI when they perceived high risk, yet they hesitated to adopt AI when the perceived risk was minimal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=risk%20perception" title="risk perception">risk perception</a>, <a href="https://publications.waset.org/abstracts/search?q=acceptance" title=" acceptance"> acceptance</a>, <a href="https://publications.waset.org/abstracts/search?q=trust" title=" trust"> trust</a>, <a href="https://publications.waset.org/abstracts/search?q=medicine" title=" medicine"> medicine</a> </p> <a href="https://publications.waset.org/abstracts/193458/clinical-experience-and-perception-of-risk-affect-the-acceptance-and-trust-of-using-ai-in-medicine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193458.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">13</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">38</span> Fusionopolis: The Most Decisive Economic Power Centers of the 21st Century</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Norbert%20Csizmadia">Norbert Csizmadia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The 21st Century's main power centers are the cities. More than 52% of the world’s population lives in cities, in particular in the megacities which have a population over 10 million people and is still growing. According to various research and forecasts, the main economic concentration will be in 40 megacities and global centers. Based on various competitiveness analyzes and indices, global city centers, and city networks are outlined, but if we look at other aspects of urban development like complexity, connectivity, creativity, technological development, viability, green cities, pedestrian and child friendly cities, creative and cultural centers, cultural spaces and knowledge centers, we get a city competitiveness index with quite new complex indicators. The research shows this result. In addition to the megacities and the global centers, with the investigation of functionality, we got 64 so-called ‘fusiononopolis’ (i.e., fusion-polis) which stand for the most decisive economic power centers of the 21st century. In this city competition Asian centers considerably rise, as the world's functional city competitiveness index is being formed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=economic%20geography" title="economic geography">economic geography</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20geography" title=" human geography"> human geography</a>, <a href="https://publications.waset.org/abstracts/search?q=technological%20development" title=" technological development"> technological development</a>, <a href="https://publications.waset.org/abstracts/search?q=urbanism" title=" urbanism"> urbanism</a> </p> <a href="https://publications.waset.org/abstracts/87191/fusionopolis-the-most-decisive-economic-power-centers-of-the-21st-century" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87191.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">361</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> Impact of Zn/Cr Ratio on ZnCrOx-SAPO-34 Bifunctional Catalyst for Direct Conversion of Syngas to Light Olefins</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuxuan%20Huang">Yuxuan Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Weixin%20Qian"> Weixin Qian</a>, <a href="https://publications.waset.org/abstracts/search?q=Hongfang%20Ma"> Hongfang Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Haitao%20Zhang"> Haitao Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Weiyong%20Ying"> Weiyong Ying</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Light olefins are important building blocks for chemical industry. Direct conversion of syngas to light olefins has been investigated for decades. Meanwhile, the limit for light olefins selectivity described by Anderson-Schulz-Flory (ASF) distribution model is still a great challenge to conventional Fischer-Tropsch synthesis. The emerging strategy called oxide-zeolite concept (OX-ZEO) is a promising way to get rid of this limit. ZnCrO<sub>x</sub> was prepared by co-precipitation method and (NH<sub>4</sub>)<sub>2</sub>CO<sub>3</sub> was used as precipitant. SAPO-34 was prepared by hydrothermal synthesis, and Tetraethylammonium hydroxide (TEAOH) was used as template, while silica sol, pseudo-boehmite, and phosphoric acid were Al, Si and P source, respectively. The bifunctional catalyst was prepared by mechanical mixing of ZnCrO<sub>x</sub> and SAPO-34. Catalytic reactions were carried out under H<sub>2</sub>/CO=2, 380 ℃, 1 MPa and 6000 mL·g<sub>cat</sub><sup>-1</sup>·h<sup>-1</sup> in a fixed-bed reactor with a quartz lining. Catalysts were characterized by XRD, N<sub>2</sub> adsorption-desorption, NH<sub>3</sub>-TPD, H<sub>2</sub>-TPR, and CO-TPD. The addition of Al as structure promoter enhances CO conversion and selectivity to light olefins. Zn/Cr ratio, which decides the active component content and chemisorption property of the catalyst, influences CO conversion and selectivity to light olefins at the same time. C<sub>2-4</sub><sup>=</sup> distribution of 86% among hydrocarbons at CO conversion of 14% was reached when Zn/Cr=1.5. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=light%20olefins" title="light olefins">light olefins</a>, <a href="https://publications.waset.org/abstracts/search?q=OX-ZEO" title=" OX-ZEO"> OX-ZEO</a>, <a href="https://publications.waset.org/abstracts/search?q=Syngas" title=" Syngas"> Syngas</a>, <a href="https://publications.waset.org/abstracts/search?q=ZnCrO%E2%82%93" title=" ZnCrOₓ"> ZnCrOₓ</a> </p> <a href="https://publications.waset.org/abstracts/93131/impact-of-zncr-ratio-on-zncrox-sapo-34-bifunctional-catalyst-for-direct-conversion-of-syngas-to-light-olefins" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93131.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">36</span> Realization of Wearable Inertial Measurement Units-Sensor-Fusion Harness to Control Therapeutic Smartphone Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Svilen%20Dimitrov">Svilen Dimitrov</a>, <a href="https://publications.waset.org/abstracts/search?q=Manthan%20Pancholi"> Manthan Pancholi</a>, <a href="https://publications.waset.org/abstracts/search?q=Norbert%20Schmitz"> Norbert Schmitz</a>, <a href="https://publications.waset.org/abstracts/search?q=Didier%20Stricker"> Didier Stricker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the end-to-end development of a wearable motion sensing harness consisting of computational unit and four inertial measurement units to control three smartphone therapeutic games for children.

Methods: We retrospectively analyzed patients diagnosed with ILC or IDC from 2012 to 2016 who underwent surgery. Patients constituted 493 primary early breast cancer cases (82 ILC; 411 IDC). Results: Compared with IDC, ILC tumors were significantly more likely to be grade 2, estrogen receptor- (ER) positive (þ), have a lower proliferation rate (Ki67 <14%), and a higher patholog- ical T stage (pT2–4). The luminal A subtype was significantly more common in ILC compared with IDC. In a multivariate regression model, grade 2, ERþ, progesterone receptor-positive, pT2, and pT3 were significantly associated with ILC. Additionally, with the luminal A subtype, ALN involvement (pathological node stage (pN)1–3) was significantly more frequent with ILC versus IDC. Conclusions: Our data suggests that grade 2, positive hormone receptor status, and higher pathological T stage are associated with ILC. With the luminal A subtype, ALN involvement was more frequent with ILC versus IDC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=lobular%20histology" title=" lobular histology"> lobular histology</a>, <a href="https://publications.waset.org/abstracts/search?q=tumor%20biology" title=" tumor biology"> tumor biology</a>, <a href="https://publications.waset.org/abstracts/search?q=hormone%20receptor" title=" hormone receptor"> hormone receptor</a>, <a href="https://publications.waset.org/abstracts/search?q=ki67" title=" ki67"> ki67</a> </p> <a href="https://publications.waset.org/abstracts/193830/tumor-biological-characteristics-of-invasive-lobular-carcinoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193830.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">9</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> Sense of the Place and Human Multisensory Perceptions: The Case of Kerman Old Bazaar Scents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabra%20Saeidi">Sabra Saeidi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> When we talk about tangible heritage, the first thing that comes to mind is historic places: what they look like, who made them, and what materials they are made of. But each monument is not limited to its physical constituents and is a complex and related set of human perceptions, memories, narratives, and the structure that shapes its character. In this article, based on the ideology of two great architects, Juhani Pallasmaa and Christian Norberg-Schulz, we discussed the sense of the place and how the human presence in a place with all its senses (visual, auditory, tactile, olfactory, taste) gives life and value to it. This value is all about feeling and definitions and is recorded in the form of our memoirs. An attempt has been made to conclude that our perception of the environment, by our sensory tools, is an intangible and thematic heritage itself, whose existence depends on our existence and has no less value than monuments' physical form and structure. The sense of smell is one of the most powerful, personal and inexplicable, unrecorded, and unexpressed senses and has a solid connection with our memories. by reviewing the case of Kerman Bazaar and its change of use in recent years, we define that one of the ways to protect the olfactory heritage of this valuable complex is to draw a Smellscape: a way to record the moment of present and past memories. Smellscapes are tools for transferring the sense of smell to a visual form to record scents and understand them in a more comprehensive, common, and artistic form. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sence%20of%20the%20place" title="sence of the place">sence of the place</a>, <a href="https://publications.waset.org/abstracts/search?q=spirit%20of%20the%20place" title=" spirit of the place"> spirit of the place</a>, <a href="https://publications.waset.org/abstracts/search?q=smellscape" title=" smellscape"> smellscape</a>, <a href="https://publications.waset.org/abstracts/search?q=multisensory%20perception" title=" multisensory perception"> multisensory perception</a> </p> <a href="https://publications.waset.org/abstracts/150450/sense-of-the-place-and-human-multisensory-perceptions-the-case-of-kerman-old-bazaar-scents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150450.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">33</span> The Use of Phototherapy with Unusual Case Studies in Counselling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Briar%20Schulz">Briar Schulz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of phototherapy within the counselling room offers significant advantages in extending far beyond typical "talk therapy" avenues. The benefits of using this approach are numerous and include: efficiency in recalling pertinent information in addition to utilizing a visual lens that often captures opulent detail that can be eluded in traditional dialogue. The goal of this presentation is to provide conference attendees with an opportunity to understand the therapeutic benefits and creative possibilities of incorporating photography into the clinical counselling process. This includes practical strategies for using in specific case studies, where studies of phototherapy have previously been limited. Ethical considerations and limitations to the process will also be addressed. Attendees will observe the benefits of using phototherapy with six longitudinal case studies including: a 30 year old female, with anorexia nervosa; a 22 year old self-harming individual with obsessive compulsive disorder; a 24 year old client with developmental delays, and bipolar disorder; a 14 year old client with Autism; and two clients with rare medical conditions struggling with depression and anxiety, one 21 years old and the other 16 years old. Aspects of each case will be linked to various theoretical modalities to highlight the efficiency and benefits of phototherapy in drawing important clinical conclusions. Furthermore, the use of phototherapy within these clinical areas remains a relatively unexplored area of the literature, and possibilities for future research will be highlighted. Finally, conference attendees will have the opportunity to try various phototherapy strategies within the interactive portion of this presentation. . <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atypical" title="Atypical">Atypical</a>, <a href="https://publications.waset.org/abstracts/search?q=Case%20studies" title=" Case studies"> Case studies</a>, <a href="https://publications.waset.org/abstracts/search?q=Phototherapy" title=" Phototherapy"> Phototherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=Photovoice" title=" Photovoice"> Photovoice</a> </p> <a href="https://publications.waset.org/abstracts/124002/the-use-of-phototherapy-with-unusual-case-studies-in-counselling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124002.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">149</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> Experimental Assessment of a Grid-Forming Inverter in Microgrid Islanding Operation Mode</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dalia%20Salem">Dalia Salem</a>, <a href="https://publications.waset.org/abstracts/search?q=Detlef%20Schulz"> Detlef Schulz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As Germany pursues its ambitious plan towards a power system based on renewable energy sources, the necessity to establish steady, robust microgrids becomes more evident. Inside the microgrid, there is at least one grid-forming inverter responsible for generating the coupling voltage and stabilizing the system frequency within the standardized accepted limits when the microgrid is forced to operate as a stand-alone power system. Grid-forming control for distributed inverters is required to enable steady control of a low-inertia power system. In this paper, a designed droop control technique is tested at the controller of an inverter as a component of a hardware test bed to understand the microgrid behavior in two modes of operation: i) grid-connected and ii) operating in islanding mode. This droop technique includes many current and voltage inner control loops, where the Q-V and P-f droop provide the required terminal output voltage and frequency. The technique is tested first in a simulation model of the inverter in MATLAB/SIMULINK, and the results are compared to the results of the hardware laboratory test. The results of this experiment illuminate the pivotal role of the grid-forming inverter in facilitating microgrid resilience during grid disconnection events and how microgrids could provide the functionality formerly provided by synchronous machinery, such as the black start process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microgrid" title="microgrid">microgrid</a>, <a href="https://publications.waset.org/abstracts/search?q=grid-forming%20inverters" title=" grid-forming inverters"> grid-forming inverters</a>, <a href="https://publications.waset.org/abstracts/search?q=droop-control" title=" droop-control"> droop-control</a>, <a href="https://publications.waset.org/abstracts/search?q=islanding-operation" title=" islanding-operation"> islanding-operation</a> </p> <a href="https://publications.waset.org/abstracts/172730/experimental-assessment-of-a-grid-forming-inverter-in-microgrid-islanding-operation-mode" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172730.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">70</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> In vitro Effects of Berberine on the Vitality and Oxidative Profile of Bovine Spermatozoa </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eva%20Tvrd%C3%A1">Eva Tvrdá</a>, <a href="https://publications.waset.org/abstracts/search?q=Hana%20Greifov%C3%A1"> Hana Greifová</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Ivani%C4%8D"> Peter Ivanič</a>, <a href="https://publications.waset.org/abstracts/search?q=Norbert%20Luk%C3%A1%C4%8D"> Norbert Lukáč </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to evaluate the dose- and time-dependent <em>in vitro</em> effects of berberine (BER), a natural alkaloid with numerous biological properties on bovine spermatozoa during three time periods (0 h, 2 h, 24 h). Bovine semen samples were diluted and cultivated in physiological saline solution containing 0.5% DMSO together with 200, 100, 50, 10, 5, and 1 μmol/L BER. Spermatozoa motility was assessed using the computer assisted semen analyzer. The viability of spermatozoa was assessed by the metabolic (MTT) assay, production of superoxide radicals was quantified using the nitroblue tetrazolium (NBT) test, and chemiluminescence was used to evaluate the generation of reactive oxygen species (ROS). Cell lysates were prepared and the extent of lipid peroxidation (LPO) was evaluated using the TBARS assay. The results of the movement activity showed a significant increase in the motility during long term cultivation in case of concentrations ranging between 1 and 10 μmol/L BER (P < 0.01; P < 0.001; 24 h). At the same time, supplementation of 1, 5 and 10 μmol/L BER led to a significant preservation of the cell viability (P < 0.001; 24 h). BER addition at a range of 1-50 μmol/L also provided a significantly higher protection against superoxide (P < 0.05) and ROS (P < 0.001; P < 0.01) overgeneration as well as LPO (P < 0.01; P<0.05) after a 24 h cultivation. We may suggest that supplementation of BER to bovine spermatozoa, particularly at concentrations ranging between 1 and 50 μmol/L, may offer protection to the motility, viability and oxidative status of the spermatozoa, particularly notable at 24 h. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=berberine" title="berberine">berberine</a>, <a href="https://publications.waset.org/abstracts/search?q=bulls" title=" bulls"> bulls</a>, <a href="https://publications.waset.org/abstracts/search?q=motility" title=" motility"> motility</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20profile" title=" oxidative profile"> oxidative profile</a>, <a href="https://publications.waset.org/abstracts/search?q=spermatozoa" title=" spermatozoa"> spermatozoa</a>, <a href="https://publications.waset.org/abstracts/search?q=viability" title=" viability"> viability</a> </p> <a href="https://publications.waset.org/abstracts/108980/in-vitro-effects-of-berberine-on-the-vitality-and-oxidative-profile-of-bovine-spermatozoa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108980.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">130</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> Agile Implementation of 'PULL' Principles in a Manufacturing Process Chain for Aerospace Composite Parts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Torsten%20Mielitz">Torsten Mielitz</a>, <a href="https://publications.waset.org/abstracts/search?q=Dietmar%20Schulz"> Dietmar Schulz</a>, <a href="https://publications.waset.org/abstracts/search?q=York%20C.%20Roth"> York C.

Improvements and optimizations in the industrial system are becoming more important to cope with future challenges in manufacturing and assembly. Highest quality standards have to be met for aerospace parts, whereas cost effective production in industrial systems and methodologies are also a key driver. A look at other industries like e.g., automotive shows well established processes to streamline existing manufacturing systems. In this paper, the implementation of 'PULL' principles in an existing manufacturing process chain for a large scale composite part is presented. A nonlinear extrapolation based on 'Little's Law' showed a risk of a significant increase of parts needed in the process chain to meet future demand. A project has been set up to mitigate the risk whereas the methodology has been changed from a traditional milestone approach in the beginning towards an agile way of working in the end in order to facilitate immediate benefits in the shop-floor. Finally, delivery rates could be increased avoiding more semi-finished parts in the process chain (work in progress & inventory) by the successful implementation of the 'PULL' philosophy in the shop-floor between the work stations. Lessons learned during the running project as well as implementation and operations phases are discussed in order to share best practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerospace%20composite%20part%20manufacturing" title="aerospace composite part manufacturing">aerospace composite part manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=PULL%20principles" title=" PULL principles"> PULL principles</a>, <a href="https://publications.waset.org/abstracts/search?q=shop-floor%20implementation" title=" shop-floor implementation"> shop-floor implementation</a>, <a href="https://publications.waset.org/abstracts/search?q=lessons%20learned" title=" lessons learned"> lessons learned</a> </p> <a href="https://publications.waset.org/abstracts/95112/agile-implementation-of-pull-principles-in-a-manufacturing-process-chain-for-aerospace-composite-parts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95112.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">29</span> The Power of Geography in the Multipolar World Order</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Norbert%20Csizmadia">Norbert Csizmadia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper is based on a thorough investigation regarding the recent global, social and geographical processes. The ‘Geofusion’ book series by the author guides the readers with the help of newly illustrated “associative” geographic maps of the global world in the 21st century through the quest for the winning nations, communities, leaders and powers of this age. Hence, the above mentioned represent the research objectives, the preliminary findings of which are presented in this paper. The most significant recognition is that scientists who are recognized as explorers, geostrategists of this century, in this case, are expected to present guidelines for our new world full of global social and economic challenges. To do so, new maps are needed which do not miss the wisdom and tools of the old but complement them with the new structure of knowledge. Using the lately discovered geographic and economic interrelations, the study behind this presentation tries to give a prognosis of the global processes. The methodology applied contains the survey and analysis of many recent publications worldwide regarding geostrategic, cultural, geographical, social, and economic surveys structured into global networks. In conclusion, the author presents the result of the study, which is a collage of the global map of the 21st century as mentioned above, and it can be considered as a potential contribution to the recent scientific literature on the topic. In summary, this paper displays the results of several-year-long research giving the audience an image of how economic navigation tools can help investors, politicians and travelers to get along in the changing new world. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geography" title="geography">geography</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20geography" title=" economic geography"> economic geography</a>, <a href="https://publications.waset.org/abstracts/search?q=geo-fusion" title=" geo-fusion"> geo-fusion</a>, <a href="https://publications.waset.org/abstracts/search?q=geostrategy" title=" geostrategy"> geostrategy</a> </p> <a href="https://publications.waset.org/abstracts/146905/the-power-of-geography-in-the-multipolar-world-order" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146905.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">131</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> Analysis of Gas Transport and Sorption Processes in Coal under Confining Pressure Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Pajdak">Anna Pajdak</a>, <a href="https://publications.waset.org/abstracts/search?q=Mateusz%20%20Kudasik"> Mateusz Kudasik</a>, <a href="https://publications.waset.org/abstracts/search?q=Norbert%20%20Skoczylas"> Norbert Skoczylas</a>, <a href="https://publications.waset.org/abstracts/search?q=Leticia%20Teixeira%20Palla%20Braga"> Leticia Teixeira Palla Braga </a> </p> <p class="card-text"><strong>Abstract:</strong></p> A substantial majority of gas transport and sorption researches into coal are carried out on samples that are free of stress. In natural conditions, coal occurs at considerable depths, which often exceed 1000 meters. In such conditions, coal is subjected to geostatic pressure. Thus, in natural conditions, the sorption capacity of coal subjected to geostatic pressure can differ considerably from the sorption capacity of coal, determined in laboratory conditions, which is free of stress. The work presents the results of filtration and sorption tests of gases in coal under confining pressure conditions. The tests were carried out on the author's device, which ensures: confining pressure regulation in the range of 0-30 MPa, isobaric gas pressure conditions, and registration of changes in sample volume during its gas saturation. Based on the conducted research it was found, among others, that the sorption capacity of coal relative to CO₂ was reduced by about 15% as a result of the change in the confining pressure from 1.5 MPa to 30 MPa exerted on the sample. The same change in sample load caused a significant, more than tenfold reduction in carbon permeability to CO₂. The results confirmed that a load of coal corresponding to a hydrostatic pressure of 1000 meters underground reduces its permeability and sorption properties. These results are so important that the effect of load on the sorption properties of coal should be taken into account in laboratory studies on the applicability of CO₂ Enhanced Coal Bed Methane Recovery (CO₂-ECBM) technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coal" title="coal">coal</a>, <a href="https://publications.waset.org/abstracts/search?q=confining%20pressure" title=" confining pressure"> confining pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20transport" title=" gas transport"> gas transport</a>, <a href="https://publications.waset.org/abstracts/search?q=sorption" title=" sorption"> sorption</a> </p> <a href="https://publications.waset.org/abstracts/124125/analysis-of-gas-transport-and-sorption-processes-in-coal-under-confining-pressure-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124125.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">121</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> The Effect of Curcumin on Cryopreserved Bovine Semen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eva%20Tvrd%C3%A1">Eva Tvrdá</a>, <a href="https://publications.waset.org/abstracts/search?q=Marek%20Halen%C3%A1r"> Marek Halenár</a>, <a href="https://publications.waset.org/abstracts/search?q=Hana%20Greifov%C3%A1"> Hana Greifová</a>, <a href="https://publications.waset.org/abstracts/search?q=Alica%20Mackovich"> Alica Mackovich</a>, <a href="https://publications.waset.org/abstracts/search?q=Faridullah%20Hashim"> Faridullah Hashim</a>, <a href="https://publications.waset.org/abstracts/search?q=Norbert%20Luk%C3%A1%C4%8D"> Norbert Lukáč </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Oxidative stress associated with semen cryopreservation may result in lipid peroxidation (LPO), DNA damage and apoptosis, leading to decreased sperm motility and fertilization ability. Curcumin (CUR), a natural phenol isolated from <em>Curcuma longa </em>Linn. has been presented as a possible supplement for a more effective semen cryopreservation because of its antioxidant properties. This study focused to evaluate the effects of CUR on selected oxidative stress parameters in cryopreserved bovine semen. 20 bovine ejaculates were split into two aliquots and diluted with a commercial semen extender containing CUR (50 μmol/L) or no supplement (control), cooled to 4 °C, frozen and kept in liquid nitrogen. Frozen straws were thawed in a water bath for subsequent experiments. Computer assisted semen analysis was used to evaluate spermatozoa motility, and reactive oxygen species (ROS) generation was quantified by using luminometry. Superoxide generation was evaluated with the NBT test, and LPO was assessed via the TBARS assay. CUR supplementation significantly (P<0.001) increased the spermatozoa motility and provided a significantly higher protection against ROS (P<0.001) or superoxide (P<0.01) overgeneration caused by semen freezing and thawing. Furthermore, CUR administration resulted in a significantly (P<0.01) lower LPO of the experimental semen samples. In conclusion, CUR exhibits significant ROS-scavenging activities which may prevent oxidative insults to cryopreserved spermatozoa and thus may enhance the post-thaw functional activity of male gametes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bulls" title="bulls">bulls</a>, <a href="https://publications.waset.org/abstracts/search?q=cryopreservation" title=" cryopreservation"> cryopreservation</a>, <a href="https://publications.waset.org/abstracts/search?q=curcumin" title=" curcumin"> curcumin</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid%20peroxidation" title=" lipid peroxidation"> lipid peroxidation</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20oxygen%20species" title=" reactive oxygen species"> reactive oxygen species</a>, <a href="https://publications.waset.org/abstracts/search?q=spermatozoa" title=" spermatozoa"> spermatozoa</a> </p> <a href="https://publications.waset.org/abstracts/55015/the-effect-of-curcumin-on-cryopreserved-bovine-semen" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55015.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">267</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> Development of Sports Nation on the Way of Health Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Beatrix%20Farag%C3%B3">Beatrix Faragó</a>, <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20Szak%C3%A1ly"> Zsolt Szakály</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%81gnes%20Kov%C3%A1csn%C3%A9%20T%C3%B3th"> Ágnes Kovácsné Tóth</a>, <a href="https://publications.waset.org/abstracts/search?q=Csaba%20Konczos"> Csaba Konczos</a>, <a href="https://publications.waset.org/abstracts/search?q=Norbert%20Kov%C3%A1cs"> Norbert Kovács</a>, <a href="https://publications.waset.org/abstracts/search?q=Zs%C3%B3fia%20P%C3%A1pai"> Zsófia Pápai</a>, <a href="https://publications.waset.org/abstracts/search?q=Tam%C3%A1s%20Kert%C3%A9sz"> Tamás Kertész </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The future of the nation is the embodiment of a healthy society. A key segment of government policy is the development of health and a health-oriented environment. As a result, sport as an activator of health is an important area for development. In Hungary, sport is a strategic sector with the aim of developing a sports nation. The function of sport in the global society is multifaceted, which is manifested in both social and economic terms. The economic importance of sport is gaining ground in the world, with implications for Central and Eastern Europe. Smaller states, such as Hungary, cannot ignore the economic effects of exploiting the effects of sport. The relationship between physical activity and health is driven by the health economy towards the nation's economic factor. In our research, we analyzed sport as a national strategy sector and its impact on age groups. By presenting the current state of health behavior, we get an idea of the directions where development opportunities require even more intervention. The foundation of the health of a nation is the young age group, whose shaping of health will shape the future generation. Our research was attended by university students from the Faculty of Health and Sports Sciences who will be experts in the field of health in the future. The other group is the elderly, who are a growing social group due to demographic change and are a key segment of the labor market and consumer society. Our study presents the health behavior of the two age groups, their differences, and similarities. The survey also identifies gaps in the development of a health management strategy that national strategies should take into account. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=competitiveness" title="competitiveness">competitiveness</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20behavior" title=" health behavior"> health behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20economy" title=" health economy"> health economy</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20management" title=" health management"> health management</a>, <a href="https://publications.waset.org/abstracts/search?q=sports%20nation" title=" sports nation"> sports nation</a> </p> <a href="https://publications.waset.org/abstracts/117192/development-of-sports-nation-on-the-way-of-health-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117192.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">156</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> Constitutional Identity: The Connection between National Constitutions and EU Law</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Norbert%20Tribl">Norbert Tribl</a> </p> <p class="card-text"><strong>Abstract:</strong></p> European contemporary scientific public opinion considers the concept of constitutional identity as a highlighted issue. Some scholars interpret the matter as the manifestation of a conflict of Europe. Nevertheless, constitutional identity is a bridge between the Member States and the EU rather than a river that will wash away the achievements of the integration. In accordance with the opinion of the author, the main problem of constitutional identity in Europe is the undetermined nature: the exact concept of constitutional identity has not been defined until now. However, this should be the first step to understand and use identity as a legal institution. Having regard to this undetermined nature, the legal-theoretical examination of constitutional identity is the main purpose of this study. The concept of constitutional identity appears in the Anglo-Saxon legal systems by a different approach than in the supranational system of European Integration. While the interpretation of legal institutions in conformity with the constitution is understood under it, the European concept is applied when possible conflicts arise between the legal system of the European supranational space and certain provisions of the national constitutions of the member states. The European concept of constitutional identity intends to offer input in determining the nature of the relationship between the constitutional provisions of the member states and the legal acts of the EU integration. In the EU system of multilevel constitutionalism, a long-standing central debate on integration surrounds the conflict between EU legal acts and the constitutional provisions of the member states. In spite of the fact that the Court of Justice of the European Union stated in Costa v. E.N.E.L. that the member states cannot refer to the provisions of their respective national constitutions against the integration. Based on the experience of more than 50 years since the above decision, and also in light of the Treaty of Lisbon, we now can clearly see that EU law has itself identified an obligation for the EU to protect the fundamental constitutional features of the Member States under Article 4 (2) of Treaty on European Union, by respecting the national identities of member states. In other words, the European concept intends to offer input for the determination of the nature of the relationship between the constitutional provisions of the member states and the legal acts of the EU integration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constitutional%20identity" title="constitutional identity">constitutional identity</a>, <a href="https://publications.waset.org/abstracts/search?q=EU%20law" title=" EU law"> EU law</a>, <a href="https://publications.waset.org/abstracts/search?q=European%20Integration" title=" European Integration"> European Integration</a>, <a href="https://publications.waset.org/abstracts/search?q=supranationalism" title=" supranationalism"> supranationalism</a> </p> <a href="https://publications.waset.org/abstracts/109486/constitutional-identity-the-connection-between-national-constitutions-and-eu-law" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109486.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Principles to Design Urbanism in Cinema; An Aesthetic Study on Identity and Representation of a City in a Movie</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dorsa%20Moayedi">Dorsa Moayedi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> ‘The Cities’ and Cinema have a history going as far back as silent films; however, the standards of picturing a city in a film are somewhat vague. ‘Genius Loci’ of a city can be easily described with parameters that architects have detected; nevertheless, the genius loci of an ‘urban movie’ is untouched. Cities have been among the provocative matters that pushed filmmakers to ponder upon them and to picture them along with their urban identity thoroughly in their artworks, though the impacts of the urban life on the plot and characters is neglected, and so a city in a movie is usually restricted to ‘the place where the story happens’. Cities and urban life are among those that are in constant change and ongoing expansion; therefore, they are always fresh and ready to challenge people with their existence. Thus, the relationship between the city and cinema is metamorphic, though it could be defined and explored. The dominant research on the idea of urbanism has been conducted by outstanding scholars of architecture, like Christian Norberg-Schulz, and the studies on Cinema have been done by theorists of cinema, like Christian Metz, who have mastered defining their own realm; still, the idea to mingle the domains to reach a unified theory which could be applied to ‘urban movies’ is barely worked on. In this research, we have sought mutual grounds to discuss ‘urbanism in cinema,’ the grounds that cinema could benefit from and get to a more accurate audio-visual representation of a city, in accordance with the ideas of Christopher Alexander and the term he coined ‘The Timeless Way of Building.’ We concentrate on movies that are dependent on urban life, mainly those that possess the names of cities, like ‘Nashville (1975), Manhattan (1979), Fargo (1996), Midnight in Paris (2011) or Roma (2018), according to the ideas of urban design and narratives of cinema. Contrary to what has often been assumed, cinema and architecture could be defined in line with similar parameters, and architectural terms could be applied to the research done on movies. Our findings indicate that the theories of Christopher Alexander can best fit the paradigm to study an ‘Urban Movie’, definitions of a timeless building, elaborate on the characteristics of a design that could be applied to definitions of an urban movie, and set a prototype for further filmmaking regarding the urban life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=city" title="city">city</a>, <a href="https://publications.waset.org/abstracts/search?q=urbanism" title=" urbanism"> urbanism</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20movies" title=" urban movies"> urban movies</a>, <a href="https://publications.waset.org/abstracts/search?q=identity" title=" identity"> identity</a>, <a href="https://publications.waset.org/abstracts/search?q=representation" title=" representation"> representation</a> </p> <a href="https://publications.waset.org/abstracts/182855/principles-to-design-urbanism-in-cinema-an-aesthetic-study-on-identity-and-representation-of-a-city-in-a-movie" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182855.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">65</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> In vitro Effects of Salvia officinalis on Bovine Spermatozoa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eva%20Tvrd%C3%A1">Eva Tvrdá</a>, <a href="https://publications.waset.org/abstracts/search?q=Boris%20Botman"> Boris Botman</a>, <a href="https://publications.waset.org/abstracts/search?q=Marek%20Halen%C3%A1r"> Marek Halenár</a>, <a href="https://publications.waset.org/abstracts/search?q=Tom%C3%A1%C5%A1%20Slanina"> Tomáš Slanina</a>, <a href="https://publications.waset.org/abstracts/search?q=Norbert%20Luk%C3%A1%C4%8D"> Norbert Lukáč</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <em>In vitro</em> storage and processing of animal semen represents a risk factor to spermatozoa vitality, potentially leading to reduced fertility. A variety of substances isolated from natural sources may exhibit protective or antioxidant properties on the spermatozoon, thus extending the lifespan of stored ejaculates. This study compared the ability of different concentrations of the <em>Salvia officinalis</em> extract on the motility, mitochondrial activity, viability and reactive oxygen species (ROS) production by bovine spermatozoa during different time periods (0, 2, 6 and 24 h) of <em>in vitro</em> culture. Spermatozoa motility was assessed using the Computer-assisted sperm analysis (CASA) system. Cell viability was examined using the metabolic activity MTT assay, the eosin-nigrosin staining technique was used to evaluate the sperm viability and ROS generation was quantified using luminometry. The CASA analysis revealed that the motility in the experimental groups supplemented with 0.5-2 µg/mL <em>Salvia</em> extract was significantly lower in comparison with the control (P<0.05; Time 24 h). At the same time, a long-term exposure of spermatozoa to concentrations ranging between 0.05 µg/mL and 2 µg/mL had a negative impact on the mitochondrial metabolism (P<0.05; Time 24 h). The viability staining revealed that 0.001-1 µg/mL <em>Salvia</em> extract had no effects on bovine male gametes, however 2 µg/mL <em>Salvia</em> had a persisting negative effect on spermatozoa (P<0.05). Furthermore 0.05-2 µg/mL <em>Salvia</em> exhibited an immediate ROS-promoting effect on the sperm culture (P>0.05; Time 0 h and 2 h), which remained significant throughout the entire <em>in vitro</em> culture (P<0.05; Time 24 h). Our results point out to the necessity to examine specific effects the biomolecules present in <em>Salvia officinalis</em> may have individually or collectively on the <em>in vitro</em> sperm vitality and oxidative profile. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bulls" title="bulls">bulls</a>, <a href="https://publications.waset.org/abstracts/search?q=CASA" title=" CASA"> CASA</a>, <a href="https://publications.waset.org/abstracts/search?q=MTT%20test" title=" MTT test"> MTT test</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20oxygen%20species" title=" reactive oxygen species"> reactive oxygen species</a>, <a href="https://publications.waset.org/abstracts/search?q=sage" title=" sage"> sage</a>, <a href="https://publications.waset.org/abstracts/search?q=Salvia%20officinalis" title=" Salvia officinalis"> Salvia officinalis</a>, <a href="https://publications.waset.org/abstracts/search?q=spermatozoa" title=" spermatozoa"> spermatozoa</a> </p> <a href="https://publications.waset.org/abstracts/56562/in-vitro-effects-of-salvia-officinalis-on-bovine-spermatozoa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56562.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">338</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> The Association of Slope Failure and Lineament Density along the Ranau-Tambunan Road, Sabah, Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Norbert%20Simon">Norbert Simon</a>, <a href="https://publications.waset.org/abstracts/search?q=Rodeano%20Roslee"> Rodeano Roslee</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Ghani%20Rafek"> Abdul Ghani Rafek</a>, <a href="https://publications.waset.org/abstracts/search?q=Goh%20Thian%20Lai"> Goh Thian Lai</a>, <a href="https://publications.waset.org/abstracts/search?q=Azimah%20Hussein"> Azimah Hussein</a>, <a href="https://publications.waset.org/abstracts/search?q=Lee%20Khai%20Ern"> Lee Khai Ern</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The 54 km stretch of Ranau-Tambunan (RTM) road in Sabah is subjected to slope failures almost every year. This study is focusing on identifying section of roads that are susceptible to failure based on temporal landslide density and lineament density analyses. In addition to the analyses, the rock slopes in several sections of the road were assessed using the geological strength index (GSI) technique. The analysis involved 148 landslides that were obtained in 1978, 1994, 2009 and 2011. The landslides were digitized as points and the point density was calculated based on every 1km2 of the road. The lineaments of the area was interpreted from Landsat 7 15m panchromatic band. The lineament density was later calculated based on every 1km2 of the area using similar technique with the slope failure density calculation. The landslide and lineament densities were classified into three different classes that indicate the level of susceptibility (low, moderate, high). Subsequently, the two density maps were overlap to produce the final susceptibility map. The combination of both high susceptibility classes from these maps signifies the high potential of slope failure in those locations in the future. The final susceptibility map indicates that there are 22 sections of the road that are highly susceptible. Seven rock slopes were assessed along the RTM road using the GSI technique. It was found from the assessment that rock slopes along this road are highly fractured, weathered and can be classified into fair to poor categories. The poor condition of the rock slope can be attributed to the high lineament density that presence in the study area. Six of the rock slopes are located in the high susceptibility zones. A detailed investigation on the 22 high susceptibility sections of the RTM road should be conducted due to their higher susceptibility to failure, in order to prevent untoward incident to road users in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GSI" title="GSI">GSI</a>, <a href="https://publications.waset.org/abstracts/search?q=landslide" title=" landslide"> landslide</a>, <a href="https://publications.waset.org/abstracts/search?q=landslide%20density" title=" landslide density"> landslide density</a>, <a href="https://publications.waset.org/abstracts/search?q=landslide%20susceptibility" title=" landslide susceptibility"> landslide susceptibility</a>, <a href="https://publications.waset.org/abstracts/search?q=lineament%20density" title=" lineament density"> lineament density</a> </p> <a href="https://publications.waset.org/abstracts/42537/the-association-of-slope-failure-and-lineament-density-along-the-ranau-tambunan-road-sabah-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42537.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">398</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Efficient Energy Extraction Circuit for Impact Harvesting from High Impedance Sources</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sherif%20Keddis">Sherif Keddis</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Azzam"> Mohamed Azzam</a>, <a href="https://publications.waset.org/abstracts/search?q=Norbert%20Schwesinger"> Norbert Schwesinger</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Harvesting mechanical energy from footsteps or other impacts is a possibility to enable wireless autonomous sensor nodes. These can be used for a highly efficient control of connected devices such as lights, security systems, air conditioning systems or other smart home applications. They can also be used for accurate location or occupancy monitoring. Converting the mechanical energy into useful electrical energy can be achieved using the piezoelectric effect offering simple harvesting setups and low deflections. The challenge facing piezoelectric transducers is the achievable amount of energy per impact in the lower mJ range and the management of such low energies. Simple setups for energy extraction such as a full wave bridge connected directly to a capacitor are problematic due to the mismatch between high impedance sources and low impedance storage elements. Efficient energy circuits for piezoelectric harvesters are commonly designed for vibration harvesters and require periodic input energies with predictable frequencies. Due to the sporadic nature of impact harvesters, such circuits are not well suited. This paper presents a self-powered circuit that avoids the impedance mismatch during energy extraction by disconnecting the load until the source reaches its charge peak. The switch is implemented with passive components and works independent from the input frequency. Therefore, this circuit is suited for impact harvesting and sporadic inputs. For the same input energy, this circuit stores 150% of the energy in comparison to a directly connected capacitor to a bridge rectifier. The total efficiency, defined as the ratio of stored energy on a capacitor to available energy measured across a matched resistive load, is 63%. Although the resulting energy is already sufficient to power certain autonomous applications, further optimization of the circuit are still under investigation in order to improve the overall efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autonomous%20sensors" title="autonomous sensors">autonomous sensors</a>, <a
