Of this domain, ruminative behaviors have been considered a core feature of emotion dysregulation difficulties. Taking this into consideration, a meta-analysis was performed to assess how BPD symptoms correlate with rumination, while also considering clinical moderator variables such as comorbidity, GAF score, and type of BPD symptom and demographic moderator variables such as age, gender, and education level. Analysis of correlation across rumination domains for the entire sample revealed a medium overall correlation. When assessing types of rumination, the largest correlation was among pain rumination followed by anger, depressive, and anxious rumination. Furthermore, affective instability had the strongest correlation with increased rumination, followed by unstable relationships, identity disturbance, and self-harm/ impulsivity, respectively. Demographic variables showed no significance. Clinical implications are considered and further therapeutic interventions are discussed in the context of rumination. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=borderline%20personality%20disorder" title="borderline personality disorder">borderline personality disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=meta-analysis" title=" meta-analysis"> meta-analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=rumination" title=" rumination"> rumination</a>, <a href="https://publications.waset.org/abstracts/search?q=symptoms" title=" symptoms"> symptoms</a> </p> <a href="https://publications.waset.org/abstracts/88367/rumination-in-borderline-personality-disorder-a-meta-analytic-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88367.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">194</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> Teicoplanin Derivatives with Antiviral Activity: Synthesis and Biological Evaluation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20Szucs">Zsolt Szucs</a>, <a href="https://publications.waset.org/abstracts/search?q=Viktor%20Kelemen"> Viktor Kelemen</a>, <a href="https://publications.waset.org/abstracts/search?q=Son%20Le%20Thai"> Son Le Thai</a>, <a href="https://publications.waset.org/abstracts/search?q=Magdolna%20Csavas"> Magdolna Csavas</a>, <a href="https://publications.waset.org/abstracts/search?q=Erzsebet%20Roth"> Erzsebet Roth</a>, <a href="https://publications.waset.org/abstracts/search?q=Gyula%20Batta"> Gyula Batta</a>, <a href="https://publications.waset.org/abstracts/search?q=Annelies%20Stevaert"> Annelies Stevaert</a>, <a href="https://publications.waset.org/abstracts/search?q=Evelien%20Vanderlinden"> Evelien Vanderlinden</a>, <a href="https://publications.waset.org/abstracts/search?q=Aniko%20Borbas"> Aniko Borbas</a>, <a href="https://publications.waset.org/abstracts/search?q=Lieve%20Naesens"> Lieve Naesens</a>, <a href="https://publications.waset.org/abstracts/search?q=Pal%20Herczegh"> Pal Herczegh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The approval of modern glycopeptide antibiotics such as dalbavancin and oritavancin which have excellent activity against Gram-positive bacteria, encouraged our research group to prepare semisynthetic compounds from several members of glycopeptides by various chemical methods. Derivatives from the aglycone of ristocetin, eremomycin, vancomycin and a pseudoaglycon of teicoplanin have been synthesized in a systematic manner. Interestingly, some of the aglycoristocetin derivatives displayed noteworthy anti-influenza activity. More recently our group has been focusing on the modifications of one of the pseudoaglycons of teicoplanin. The reaction of N-ethoxycarbonyl maleimide derivatives with the primary amino function, the copper-catalysed azide-alkyne click reaction and the sulfonylation of the N-terminus were utilized to obtain systematic series of compounds. All substituents provide a more lipophilic character to the new molecules compared to the parent antibiotics, which is known to be favourable for activity against resistant bacteria. Lipoglycopeptides are also known to have antiviral properties, which has been predominantly studied on HIV by others. The structure-activity relationship study of our compounds revealed the influence of a few structural elements on biological activity. In many cases, minimal changes in lipophilicity and structure produced great differences in efficacy and cytotoxicity. In vitro experiments showed that these compounds are not only active against glycopeptide resistant Gram-positive bacteria but in several cases they prevent the infection of cell cultures by different strains of influenza viruses. This is probably related to the inhibition of the viral entry into the host cell nucleus, of which the exact mechanism is unknown. In some instances, reasonably low concentrations were sufficient to observe this effect. Several derivatives were highly cytotoxic at the same time, but some of them displayed a good selectivity index. The antiviral properties of the compounds are not restricted to influenza viruses e.g., some of them showed good activity against Human Coronavirus 229E. This work could potentially lead to the development of antiviral drugs which possess the crucial structural motifs that are needed for antiviral activity, while missing those which contribute to the antibacterial effect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antiviral" title="antiviral">antiviral</a>, <a href="https://publications.waset.org/abstracts/search?q=glycopeptide" title=" glycopeptide"> glycopeptide</a>, <a href="https://publications.waset.org/abstracts/search?q=semisynthetic" title=" semisynthetic"> semisynthetic</a>, <a href="https://publications.waset.org/abstracts/search?q=teicoplanin" title=" teicoplanin"> teicoplanin</a> </p> <a href="https://publications.waset.org/abstracts/97121/teicoplanin-derivatives-with-antiviral-activity-synthesis-and-biological-evaluation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97121.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">157</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Rank of Semigroup: Generating Sets and Cases Revealing Limitations of the Concept of Independence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20Lipcsey">Zsolt Lipcsey</a>, <a href="https://publications.waset.org/abstracts/search?q=Sampson%20Marshal%20Imeh"> Sampson Marshal Imeh </a> </p> <p class="card-text"><strong>Abstract:</strong></p> We investigate a certain characterisation for rank of a semigroup by Howie and Ribeiro (1999), to ascertain the relevance of the concept of independence.

The objective of the current study was to assess the human health risk and characterize the spatial and temporal variation of PM₂.₅ and PM₁₀ in eight Romanian regions between the 2009-2018 and. The PM concentrations showed high variability over time and spatial distribution. The highest concentration was detected in the Bucharest region in the winter period, and the lowest was detected in West. The relative risk caused by the PM₁₀ for all-cause mortality varied between 1.017 (B) and 1.025 (W), with an average 1.020. The results demonstrate a positive relative risk of cardiopulmonary and lung cancer disease due to exposure to PM₂.₅ on the national average 1.26 ( ± 0.023) and 1.42 ( ± 0.037), respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PM%E2%82%82.%E2%82%85" title="PM₂.₅">PM₂.₅</a>, <a href="https://publications.waset.org/abstracts/search?q=PM%E2%82%81%E2%82%80" title=" PM₁₀"> PM₁₀</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20risk" title=" relative risk"> relative risk</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20effect" title=" health effect"> health effect</a> </p> <a href="https://publications.waset.org/abstracts/123809/human-health-risks-assessment-of-particulate-air-pollution-in-romania" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123809.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">20</span> FEM Investigation of Inhomogeneous Wall Thickness Backward Extrusion for Aerosol Can Manufacturing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jemal%20Ebrahim%20Dessie">Jemal Ebrahim Dessie</a>, <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20Lukacs"> Zsolt Lukacs</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The wall of the aerosol can is extruded from the backward extrusion process.

Due to the thinner thickness of the wall, buckling is the critical challenge for current pure aluminum aerosol can industries. Design and investigation of extrusion with inhomogeneous wall thickness could be the best solution for reducing and optimization of neck retraction numbers. FEM simulation of inhomogeneous wall thickness has been simulated through this investigation. From axisymmetric Deform-2D backward extrusion, an aerosol can with a thickness of 0.4 mm at the top and 0.33 mm at the bottom of the aerosol can have been developed. As the result, it can optimize the number of retractions of the necking process and manufacture defect-free aerosol can shoulder due to the necking process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerosol%20can" title="aerosol can">aerosol can</a>, <a href="https://publications.waset.org/abstracts/search?q=backward%20extrusion" title=" backward extrusion"> backward extrusion</a>, <a href="https://publications.waset.org/abstracts/search?q=Deform-2D" title=" Deform-2D"> Deform-2D</a>, <a href="https://publications.waset.org/abstracts/search?q=necking" title=" necking"> necking</a> </p> <a href="https://publications.waset.org/abstracts/135808/fem-investigation-of-inhomogeneous-wall-thickness-backward-extrusion-for-aerosol-can-manufacturing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135808.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">188</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Understanding Workplace Behavior through Organizational Culture and Complex Adaptive Systems Theory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P%C3%A9ter%20Rest%C3%A1s">Péter Restás</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Czibor"> Andrea Czibor</a>, <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20P%C3%A9ter%20Szab%C3%B3"> Zsolt Péter Szabó</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: This article aims to rethink the phenomena of employee behavior as a product of a system. Both organizational culture and Complex Adaptive Systems (CAS) theory emphasize that individual behavior depends on the specific system and the unique organizational culture. These two major theories are both represented in the field of organizational studies; however, they are rarely used together for the comprehensive understanding of workplace behavior. Methodology: By reviewing the literature we use key concepts stemming from organizational culture and CAS theory in order to show the similarities between these theories and create an enriched understanding of employee behavior. Findings: a) Workplace behavior is defined here as social cognition issue. b) Organizations are discussed here as complex systems, and cultures which drive and dictate the cognitive processes of agents in the system. c) Culture gives CAS theory a context which lets us see organizations not just as ever-changing and unpredictable, but as such systems that aim to create and maintain stability by recurring behavior. Conclusion: Applying the knowledge from culture and CAS theory sheds light on our present understanding of employee behavior, also emphasizes the importance of novel ways in organizational research and management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=complex%20adaptive%20systems%20theory" title="complex adaptive systems theory">complex adaptive systems theory</a>, <a href="https://publications.waset.org/abstracts/search?q=employee%20behavior" title=" employee behavior"> employee behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20culture" title=" organizational culture"> organizational culture</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a> </p> <a href="https://publications.waset.org/abstracts/91151/understanding-workplace-behavior-through-organizational-culture-and-complex-adaptive-systems-theory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91151.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">415</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> Effects of Local Ground Conditions on Site Response Analysis Results in Hungary</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Orsolya%20Kegyes-Brassai">Orsolya Kegyes-Brassai</a>, <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20Szilv%C3%A1gyi"> Zsolt Szilvágyi</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%81kos%20Wolf"> Ákos Wolf</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20P.%20Ray"> Richard P.

Their inclusion in seismic hazard assessment and structural design can be realized at different levels of sophistication. However, response results based on more advanced calculation methods e.g. nonlinear or equivalent linear site analysis tend to show significant discrepancies when compared to simpler approaches. This project's main objective was to compare results from several 1-D response programs to Eurocode 8 design spectra. Data from in-situ site investigations were used for assessing local ground conditions at several locations in Hungary. After discussion of the in-situ measurements and calculation methods used, a comprehensive evaluation of all major contributing factors for site response is given. While the Eurocode spectra should account for local ground conditions based on soil classification, there is a wide variation in peak ground acceleration determined from 1-D analyses versus Eurocode. Results show that current Eurocode 8 design spectra may not be conservative enough to account for local ground conditions typical for Hungary. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=1-D%20site%20response%20analysis" title="1-D site response analysis">1-D site response analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=multichannel%20analysis%20of%20surface%20waves%20%28MASW%29" title=" multichannel analysis of surface waves (MASW)"> multichannel analysis of surface waves (MASW)</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20CPT" title=" seismic CPT"> seismic CPT</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20hazard%20assessment" title=" seismic hazard assessment"> seismic hazard assessment</a> </p> <a href="https://publications.waset.org/abstracts/67541/effects-of-local-ground-conditions-on-site-response-analysis-results-in-hungary" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67541.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">246</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> Normalizing Scientometric Indicators of Individual Publications Using Local Cluster Detection Methods on Citation Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Levente%20Varga">Levente Varga</a>, <a href="https://publications.waset.org/abstracts/search?q=D%C3%A1vid%20Deritei"> Dávid Deritei</a>, <a href="https://publications.waset.org/abstracts/search?q=M%C3%A1ria%20Ercsey-Ravasz"> Mária Ercsey-Ravasz</a>, <a href="https://publications.waset.org/abstracts/search?q=R%C4%83zvan%20Florian"> Răzvan Florian</a>, <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20I.%20L%C3%A1z%C3%A1r"> Zsolt I.

The issue of cross-disciplinary normalization has been long discussed, but even the classification of publications into scientific domains poses problems. Structural properties of citation networks offer new possibilities, however, the large size and constant growth of these networks asks for precaution. Here we present a new tool that in order to perform cross-field normalization of scientometric indicators of individual publications relays on the structural properties of citation networks. Due to the large size of the networks, a systematic procedure for identifying scientific domains based on a local community detection algorithm is proposed. The algorithm is tested with different benchmark and real-world networks. Then, by the use of this algorithm, the mechanism of the scientometric indicator normalization process is shown for a few indicators like the citation number, P-index and a local version of the PageRank indicator. The fat-tail trend of the article indicator distribution enables us to successfully perform the indicator normalization process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=citation%20networks" title="citation networks">citation networks</a>, <a href="https://publications.waset.org/abstracts/search?q=cross-field%20normalization" title=" cross-field normalization"> cross-field normalization</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20cluster%20detection" title=" local cluster detection"> local cluster detection</a>, <a href="https://publications.waset.org/abstracts/search?q=scientometric%20indicators" title=" scientometric indicators"> scientometric indicators</a> </p> <a href="https://publications.waset.org/abstracts/87198/normalizing-scientometric-indicators-of-individual-publications-using-local-cluster-detection-methods-on-citation-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87198.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">203</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> Ground Response Analyses in Budapest Based on Site Investigations and Laboratory Measurements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20Szilv%C3%A1gyi">Zsolt Szilvágyi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jakub%20Panuska"> Jakub Panuska</a>, <a href="https://publications.waset.org/abstracts/search?q=Orsolya%20Kegyes-Brassai"> Orsolya Kegyes-Brassai</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%81kos%20Wolf"> Ákos Wolf</a>, <a href="https://publications.waset.org/abstracts/search?q=P%C3%A9ter%20Tildy"> Péter Tildy</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20P.%20Ray"> Richard P.

It is a difficult task to model ground behavior in seismic soil-structure-foundation interaction problems, fully account for them in seismic design of structures, or even properly consider them in seismic hazard assessment. In this study, we focused on applying seismic soil investigation methods, used for determining soil stiffness and damping properties, to response analysis used in seismic design. A site in Budapest, Hungary was investigated using Multichannel Analysis of Surface Waves, Seismic Cone Penetration Tests, Bender Elements, Resonant Column and Torsional Shear tests. Our aim was to compare the results of the different test methods and use the resulting soil properties for 1D ground response analysis. Often in practice, there are little-to no data available on dynamic soil properties and estimated parameters are used for design. Therefore, a comparison is made between results based on estimated parameters and those based on detailed investigations. Ground response results are also compared to Eurocode 8 design spectra. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MASW" title="MASW">MASW</a>, <a href="https://publications.waset.org/abstracts/search?q=resonant%20column%20test" title=" resonant column test"> resonant column test</a>, <a href="https://publications.waset.org/abstracts/search?q=SCPT" title=" SCPT"> SCPT</a>, <a href="https://publications.waset.org/abstracts/search?q=site%20response%20analysis" title=" site response analysis"> site response analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=torsional%20shear%20test" title=" torsional shear test"> torsional shear test</a> </p> <a href="https://publications.waset.org/abstracts/67550/ground-response-analyses-in-budapest-based-on-site-investigations-and-laboratory-measurements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67550.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">400</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> From Synthesis to Application of Photovoltaic Perovskite Nanowires</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L%C3%A1szl%C3%B3%20Forr%C3%B3">László Forró</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The organolead halide perovskite CH3NH3PbI3 and its derivatives are known to be very efficient light harvesters revolutionizing the field of solid-state solar cells. The major research area in this field is photovoltaic device engineering although other applications are being explored, as well. Recently, we have shown that nanowires of this photovoltaic perovskite can be synthesized which in association with carbon nanostructures (carbon nanotubes and graphene) make outstanding composites with rapid and strong photo-response. They can serve as conducting electrodes, or as central components of detectors. The performance of several miniature devices based on these composite structures will be demonstrated. Our latest findings on the guided growth of perovskite nanowires by solvatomorph graphoepitaxy will be presented. This method turned out to be a fairly simple approach to overcome the spatially random surface nucleation. The process allows the synthesis of extremely long (centimeters) and thin (a few nanometers) nanowires with a morphology defined by the shape of nanostructured open fluidic channels. This low-temperature solution-growth method could open up an entirely new spectrum of architectural designs of organometallic-halide-perovskite-based heterojunctions and tandem solar cells, LEDs and other optoelectronic devices.

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">13</span> Preparation of Nano-Scaled linbo3 by Polyol Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gabriella%20Dravecz">Gabriella Dravecz</a>, <a href="https://publications.waset.org/abstracts/search?q=L%C3%A1szl%C3%B3%20P%C3%A9ter"> László Péter</a>, <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20Kis"> Zsolt Kis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Abstract— The growth of optical LiNbO3 single crystal and its physical and chemical properties are well known on the macroscopic scale. Nowadays the rare-earth doped single crystals became important for coherent quantum optical experiments: electromagnetically induced transparency, slow down of light pulses, coherent quantum memory. The expansion of applications is increasingly requiring the production of nano scaled LiNbO3 particles. For example, rare-earth doped nanoscaled particles of lithium niobate can be act like single photon source which can be the bases of a coding system of the quantum computer providing complete inaccessibility to strangers. The polyol method is a chemical synthesis where oxide formation occurs instead of hydroxide because of the high temperature. Moreover the polyol medium limits the growth and agglomeration of the grains producing particles with the diameter of 30-200 nm. In this work nano scaled LiNbO3 was prepared by the polyol method. The starting materials (niobium oxalate and LiOH) were diluted in H2O2. Then it was suspended in ethylene glycol and heated up to about the boiling point of the mixture with intensive stirring. After the thermal equilibrium was reached, the mixture was kept in this temperature for 4 hours. The suspension was cooled overnight. The mixture was centrifuged and the particles were filtered. Dynamic Light Scattering (DLS) measurement was carried out and the size of the particles were found to be 80-100 nms. This was confirmed by Scanning Electron Microscope (SEM) investigations. The element analysis of SEM showed large amount of Nb in the sample. The production of LiNbO3 nano particles were succesful by the polyol method. The agglomeration of the particles were avoided and the size of 80-100nm could be reached. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lithium-niobate" title="lithium-niobate">lithium-niobate</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title=" nanoparticles"> nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=polyol" title=" polyol"> polyol</a>, <a href="https://publications.waset.org/abstracts/search?q=SEM" title=" SEM"> SEM</a> </p> <a href="https://publications.waset.org/abstracts/136694/preparation-of-nano-scaled-linbo3-by-polyol-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136694.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">134</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> The Flashnews as a Commercial Session of Political Marketing: The Content Analysis of the Embedded Political Narratives in Non-Political Media Products</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20Szabolcsi">Zsolt Szabolcsi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Political communication in Hungary has undergone a significant change in the 2010s. One element of the transformation is the Flashnews. This media product was launched in March 2015 and since then 40-50 blocks are broadcasted, daily, on 5 channels. Flashnews blocks are condensed news sessions, containing the summary of political narratives. It starts with the introduction of the narrator, then, usually four news topics are presented and, finally, the narrator concludes the block. The block lasts only one minute and, therefore, it provides a blink session into the main narratives of political communication at the time. Beyond its rapid pace, what makes its avoidance difficult is that these blocks are always in the first position in the commercial break of a non-political media product. Although it is only one minute long, its significance is high. The content of the Flashnews reflects the main governmental narratives and, therefore, the Flashnews is part of the agenda-setting capacity of political communication. It reaches media consumers who have limited knowledge and interest in politics, and their use of media products is not politically related. For this audience, the Flashnews pops up in the same way as commercials. Due to its structure and appearance, the impact of Flashnews seems to be similar to commercials, imbedded into the break of media products. It activates existing knowledge constructs, builds up associational links and maintains their presence in a way that the recipient is not aware of the phenomenon. The research aims to examine the extent to which the Flashnews and the main news narratives are identical in their content. This aim is realized with the content analysis of the two news products by examining the Flashnews and the evening news during main sport events from 2016 to 2018. The initial hypothesis of the research is that Flashnews is a contribution to the news management technique for an effective articulation of political narratives in public service media channels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flashnews" title="flashnews">flashnews</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20communication" title=" political communication"> political communication</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20marketing" title=" political marketing"> political marketing</a>, <a href="https://publications.waset.org/abstracts/search?q=news%20management" title=" news management"> news management</a> </p> <a href="https://publications.waset.org/abstracts/127578/the-flashnews-as-a-commercial-session-of-political-marketing-the-content-analysis-of-the-embedded-political-narratives-in-non-political-media-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127578.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">135</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Attempts for the Synthesis of Indol-Ring Fluorinated Tryptophan Derivatives to Enhance the Activity of Antimicrobial Peptides</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anita%20K.%20Kovacs">Anita K.

Multiple-fluorinated indole-ring-containing tryptophan derivatives have the potential of having better antimicrobial activity than the widely used mono-fluorinated indole-ring containing tryptophan derivatives, but they are not available commercially. Therefore, our goal is to synthesize multiple-fluorinated indole-ring containing tryptophan derivatives to incorporate them into AMPs to enhance their antimicrobial activity. During our work, we are trying several methods (classical organic synthesis, enzymic synthesis, and solid phase peptide synthesis) for the synthesis of the said compounds, with mixed results. With classical organic synthesis (four different routes), we did not get the desired results. The reaction of serin with substituted indole in the presence of acetic anhydride led to racemic tryptophane; with the reaction of protected serin with indole in the presence of nickel complex was unsuccessful; the reaction of serin containing protected dipeptide with disuccinimidyl carbonate we achieved a tryptophane containing dipeptide, its chiral purity is being examined; the reaction of alcohol with substituted indole in the presence of copper complex was successful, but it was only a test reaction, we could not reproduce the same result with serine. The undergoing tryptophan-synthase method has shown some potential, but our work has not been finished yet. The successful synthesis of the desired multiple-fluorinated indole-ring-containing tryptophan will be followed by solid phase peptide synthesis in order to incorporate it into AMPs to enhance their antimicrobial activity. The successful completion of these phases will mean the possibility of manufacturing new, effective AMPs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=halogenation" title="halogenation">halogenation</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorination" title=" fluorination"> fluorination</a>, <a href="https://publications.waset.org/abstracts/search?q=tryptophan" title=" tryptophan"> tryptophan</a>, <a href="https://publications.waset.org/abstracts/search?q=enhancement%20of%20antimicrobial%20activity" title=" enhancement of antimicrobial activity"> enhancement of antimicrobial activity</a> </p> <a href="https://publications.waset.org/abstracts/152468/attempts-for-the-synthesis-of-indol-ring-fluorinated-tryptophan-derivatives-to-enhance-the-activity-of-antimicrobial-peptides" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152468.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">97</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Soil Bioremediation Monitoring Systems Powered by Microbial Fuel Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A1s%20F%C3%BCl%C3%B6p">András Fülöp</a>, <a href="https://publications.waset.org/abstracts/search?q=Lejla%20Heilmann"> Lejla Heilmann</a>, <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20Szab%C3%B3"> Zsolt Szabó</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%81kos%20Ko%C3%B3s"> Ákos Koós</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Microbial fuel cells (MFCs) present a sustainable biotechnological solution to future energy demands. The aim of this study was to construct soil based, single cell, membrane-less MFC systems, operated without treatment to continuously power on-site monitoring and control systems during the soil bioremediation processes. Our Pseudomonas aeruginosa 541 isolate is an ideal choice for MFCs, because it is able to produce pyocyanin which behaves as electron-shuttle molecule, furthermore, it also has a significant antimicrobial effect. We tested several materials and structural configurations to obtain long term high power output. Comparing different configurations, a proton exchange membrane-less, 0.6 m long with 0.05 m diameter MFC tubes offered the best long-term performances. The long-term electricity production were tested from starch, yeast extract (YE), carboxymethyl cellulose (CMC) with humic acid (HA) as a mediator. In all cases, 3 kΩ external load have been used. The two best-operated systems were the Pseudomonas aeruginosa 541 containing MFCs with 1 % carboxymethyl cellulose and the MFCs with 1% yeast extract in the anode area and 35% hydrogel in the cathode chamber. The first had 3.3 ± 0.033 mW/m2 and the second had 4.1 ± 0.065 mW/m2 power density values. These systems have operated for 230 days without any treatment. The addition of 0.2 % HA and 1 % YE referred to the volume of the anode area resulted in 1.4 ± 0.035 mW/m2 power densities. The mixture of 1% starch with 0.2 % HA gave 1.82 ± 0.031 mW/m2. Using CMC as retard carbon source takes effect in the long-term bacterial survivor, thus enable the expression of the long term power output. The application of hydrogels in the cathode chamber significantly increased the performance of the MFC units due to their good water retention capacity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microbial%20fuel%20cell" title="microbial fuel cell">microbial fuel cell</a>, <a href="https://publications.waset.org/abstracts/search?q=bioremediation" title=" bioremediation"> bioremediation</a>, <a href="https://publications.waset.org/abstracts/search?q=Pseudomonas%20aeruginosa" title=" Pseudomonas aeruginosa"> Pseudomonas aeruginosa</a>, <a href="https://publications.waset.org/abstracts/search?q=biotechnological%20solution" title=" biotechnological solution"> biotechnological solution</a> </p> <a href="https://publications.waset.org/abstracts/25292/soil-bioremediation-monitoring-systems-powered-by-microbial-fuel-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25292.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">291</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Prediction of Springback in U-bending of W-Temper AA6082 Aluminum Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jemal%20Ebrahim%20Dessie">Jemal Ebrahim Dessie</a>, <a href="https://publications.waset.org/abstracts/search?q=Luk%C3%A1cs%20Zsolt"> Lukács Zsolt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> High-strength aluminum alloys have drawn a lot of attention because of the expanding demand for lightweight vehicle design in the automotive sector. Due to poor formability at room temperature, warm and hot forming have been advised. However, warm and hot forming methods need more steps in the production process and an advanced tooling system. In contrast, since ordinary tools can be used, forming sheets at room temperature in the W temper condition is advantageous. However, springback of supersaturated sheets and their thinning are critical challenges and must be resolved during the use of this technique. In this study, AA6082-T6 aluminum alloy was solution heat treated at different oven temperatures and times using a specially designed and developed furnace in order to optimize the W-temper heat treatment temperature. A U-shaped bending test was carried out at different time periods between W-temper heat treatment and forming operation. Finite element analysis (FEA) of U-bending was conducted using AutoForm aiming to validate the experimental result. The uniaxial tensile and unload test was performed in order to determine the kinematic hardening behavior of the material and has been optimized in the Finite element code using systematic process improvement (SPI). In the simulation, the effect of friction coefficient & blank holder force was considered. Springback parameters were evaluated by the geometry adopted from the NUMISHEET ’93 benchmark problem. It is noted that the change of shape was higher at the more extended time periods between W-temper heat treatment and forming operation. Die radius was the most influential parameter at the flange springback. However, the change of shape shows an overall increasing tendency on the sidewall as the increase of radius of the punch than the radius of the die. The springback angles on the flange and sidewall seem to be highly influenced by the coefficient of friction than blank holding force, and the effect becomes increases as increasing the blank holding force. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminum%20alloy" title="aluminum alloy">aluminum alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=FEA" title=" FEA"> FEA</a>, <a href="https://publications.waset.org/abstracts/search?q=springback" title=" springback"> springback</a>, <a href="https://publications.waset.org/abstracts/search?q=SPI" title=" SPI"> SPI</a>, <a href="https://publications.waset.org/abstracts/search?q=U-bending" title=" U-bending"> U-bending</a>, <a href="https://publications.waset.org/abstracts/search?q=W-temper" title=" W-temper"> W-temper</a> </p> <a href="https://publications.waset.org/abstracts/159987/prediction-of-springback-in-u-bending-of-w-temper-aa6082-aluminum-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159987.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">100</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Comparison of Soils of Hungarian Dry and Humid Oak Forests Based on Changes in Nutrient Content</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Istv%C3%A1n%20Fekete">István Fekete</a>, <a href="https://publications.waset.org/abstracts/search?q=Imre%20Berki"> Imre Berki</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%81ron%20B%C3%A9ni"> Áron Béni</a>, <a href="https://publications.waset.org/abstracts/search?q=Katalin%20Juhos"> Katalin Juhos</a>, <a href="https://publications.waset.org/abstracts/search?q=Marianna%20Mak%C3%A1di"> Marianna Makádi</a>, <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20Kotrocz%C3%B3"> Zsolt Kotroczó</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The average annual precipitation significantly influences the moisture content of the soils and, through this, the decomposition of the organic substances in the soils, the leaching of nutrients from the soils, and the pH of the soils. Climate change, together with the lengthening of the vegetation period and the increasing CO₂ level, can increase the amount of biomass that is formed. Degradation processes, which accelerate as the temperature increases and slow down due to the drying climate, and the change in the degree of leaching can cancel out or strengthen each other's effects. In the course of our research, we looked for oak forests with climate-zonal soils where the geological, geographical and ecological background conditions are as similar as possible, apart from the different annual precipitation averages and the differences that can arise from them. We examined 5 dry and 5 humid Hungarian oak soils. Climate change affects the soils of drier and wetter forests differently. The aim of our research was to compare the content of carbon, nitrogen and some other nutrients, as well as the pH of the soils of humid and dry forests. Showing the effects of the drier climate on the tested soil parameters. In the case of the examined forest soils, we found a significant difference between the soils of dry and humid forests: in the case of the annual average precipitation values (p≥ 0.0001, for dry forest soils: 564±5.2 mm; for humid forest soils: 716±3.8 mm) for pH (p= 0.0004, for dry forest soils: 5.49±0.16; for wet forest soils: 5.36±0.21); for C content (p= 0.0054, for dry forest soils: 6.92%±0.59; for humid forest soils 3.09%±0.24), for N content (p= 0.0022, dry forest in the case of soils: 0.44%±0.047; in the case of humid forest soils: 0.23%±0.013), for the K content (p=0.0017, in the case of dry forest soils: 5684±732 (mg/kg); in the case of humid forest soils 2169±196 (mg/kg)), for the Ca content (p= 0.0096, for dry forest soils: 8207±2118 (mg/kg); for wet forest soils 957±320 (mg/kg)). No significant difference was found in the case of Mg. In a wetter environment, especially if the moisture content of the soil is also optimal for the decomposing organisms during the growing season, the decomposition of organic residues accelerates, and the processes of leaching from the soil are also intensified. The different intensity of the leaching processes is also well reflected in the quantitative differences of Ca and K, and in connection with these, it is also reflected in the difference in pH values. The differences in the C and N content can be explained by differences in the intensity of the decomposition processes. In addition to warming, drying is expected in a significant part of Hungary due to climate change. Thus, the comparison of the soils of dry and humid forests allows us to predict the subsequent changes in the case of the examined parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soil%20nutrients" title="soil nutrients">soil nutrients</a>, <a href="https://publications.waset.org/abstracts/search?q=precipitation%20difference" title=" precipitation difference"> precipitation difference</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20matter%20decomposition" title=" organic matter decomposition"> organic matter decomposition</a>, <a href="https://publications.waset.org/abstracts/search?q=leaching" title=" leaching"> leaching</a> </p> <a href="https://publications.waset.org/abstracts/161235/comparison-of-soils-of-hungarian-dry-and-humid-oak-forests-based-on-changes-in-nutrient-content" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161235.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">74</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Fabrication and Characterisation of Additive Manufactured Ti-6Al-4V Parts by Laser Powder Bed Fusion Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Norica%20Godja">Norica Godja</a>, <a href="https://publications.waset.org/abstracts/search?q=Andreas%20Schindel"> Andreas Schindel</a>, <a href="https://publications.waset.org/abstracts/search?q=Luka%20Payrits"> Luka Payrits</a>, <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20Pasztor"> Zsolt Pasztor</a>, <a href="https://publications.waset.org/abstracts/search?q=B%C3%A1lint%20Heged%C3%BCs"> Bálint Hegedüs</a>, <a href="https://publications.waset.org/abstracts/search?q=Petr%20Homola"> Petr Homola</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Hor%C5%88as"> Jan Horňas</a>, <a href="https://publications.waset.org/abstracts/search?q=Ji%C5%99%C3%AD%20B%C4%9Bhal"> Jiří Běhal</a>, <a href="https://publications.waset.org/abstracts/search?q=Roman%20Ruzek"> Roman Ruzek</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Holzleitner"> Martin Holzleitner</a>, <a href="https://publications.waset.org/abstracts/search?q=Sascha%20Senck"> Sascha Senck</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to reduce fuel consumption and CO₂ emissions in the aviation sector, innovative solutions are being sought to reduce the weight of aircraft, including additive manufacturing (AM). Of particular importance are the excellent mechanical properties that are required for aircraft structures. Ti6Al4V alloys, with their high mechanical properties in relation to weight, can reduce the weight of aircraft structures compared to structures made of steel and aluminium. Currently, conventional processes such as casting and CNC machining are used to obtain the desired structures, resulting in high raw material removal, which in turn leads to higher costs and impacts the environment. Additive manufacturing (AM) offers advantages in terms of weight, lead time, design, and functionality and enables the realisation of alternative geometric shapes with high mechanical properties. However, there are currently technological shortcomings that have led to AM not being approved for structural components with high safety requirements. An assessment of damage tolerance for AM parts is required, and quality control needs to be improved. Pores and other defects cannot be completely avoided at present, but they should be kept to a minimum during manufacture. The mechanical properties of the manufactured parts can be further improved by various treatments. The influence of different treatment methods (heat treatment, CNC milling, electropolishing, chemical polishing) and operating parameters were investigated by scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM/EDX), X-ray diffraction (XRD), electron backscatter diffraction (EBSD) and measurements with a focused ion beam (FIB), taking into account surface roughness, possible anomalies in the chemical composition of the surface and possible cracks. The results of the characterisation of the constructed and treated samples are discussed and presented in this paper. These results were generated within the framework of the 3TANIUM project, which is financed by EU with the contract number 101007830. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ti6Al4V%20alloys" title="Ti6Al4V alloys">Ti6Al4V alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=laser%20powder%20bed%20fusion" title=" laser powder bed fusion"> laser powder bed fusion</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20tolerance" title=" damage tolerance"> damage tolerance</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20treatment" title=" heat treatment"> heat treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=electropolishing" title=" electropolishing"> electropolishing</a>, <a href="https://publications.waset.org/abstracts/search?q=potential%20cracking" title=" potential cracking"> potential cracking</a> </p> <a href="https://publications.waset.org/abstracts/146535/fabrication-and-characterisation-of-additive-manufactured-ti-6al-4v-parts-by-laser-powder-bed-fusion-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146535.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">85</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Artificial Neural Network Model Based Setup Period Estimation for Polymer Cutting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20J%C3%A1nos%20Viharos">Zsolt János Viharos</a>, <a href="https://publications.waset.org/abstracts/search?q=Kriszti%C3%A1n%20Bal%C3%A1zs%20Kis"> Krisztián Balázs Kis</a>, <a href="https://publications.waset.org/abstracts/search?q=Imre%20Paniti"> Imre Paniti</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%A1bor%20Bels%C5%91"> Gábor Belső</a>, <a href="https://publications.waset.org/abstracts/search?q=P%C3%A9ter%20N%C3%A9meth"> Péter Németh</a>, <a href="https://publications.waset.org/abstracts/search?q=J%C3%A1nos%20Farkas"> János Farkas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper presents the results and industrial applications in the production setup period estimation based on industrial data inherited from the field of polymer cutting. The literature of polymer cutting is very limited considering the number of publications. The first polymer cutting machine is known since the second half of the 20th century; however, the production of polymer parts with this kind of technology is still a challenging research topic. The products of the applying industrial partner must met high technical requirements, as they are used in medical, measurement instrumentation and painting industry branches. Typically, 20% of these parts are new work, which means every five years almost the entire product portfolio is replaced in their low series manufacturing environment. Consequently, it requires a flexible production system, where the estimation of the frequent setup periods' lengths is one of the key success factors. In the investigation, several (input) parameters have been studied and grouped to create an adequate training information set for an artificial neural network as a base for the estimation of the individual setup periods. In the first group, product information is collected such as the product name and number of items. The second group contains material data like material type and colour. In the third group, surface quality and tolerance information are collected including the finest surface and tightest (or narrowest) tolerance. The fourth group contains the setup data like machine type and work shift. One source of these parameters is the Manufacturing Execution System (MES) but some data were also collected from Computer Aided Design (CAD) drawings. The number of the applied tools is one of the key factors on which the industrial partners’ estimations were based previously. The artificial neural network model was trained on several thousands of real industrial data. The mean estimation accuracy of the setup periods' lengths was improved by 30%, and in the same time the deviation of the prognosis was also improved by 50%. Furthermore, an investigation on the mentioned parameter groups considering the manufacturing order was also researched. The paper also highlights the manufacturing introduction experiences and further improvements of the proposed methods, both on the shop floor and on the quotation preparation fields. Every week more than 100 real industrial setup events are given and the related data are collected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20network" title="artificial neural network">artificial neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20series%20manufacturing" title=" low series manufacturing"> low series manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20cutting" title=" polymer cutting"> polymer cutting</a>, <a href="https://publications.waset.org/abstracts/search?q=setup%20period%20estimation" title=" setup period estimation"> setup period estimation</a> </p> <a href="https://publications.waset.org/abstracts/57280/artificial-neural-network-model-based-setup-period-estimation-for-polymer-cutting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57280.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">245</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Post-Harvest Biopreservation of Fruit and Vegetables with Application of Lactobacillus Strains </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Judit%20Perjessy">Judit Perjessy</a>, <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20Zalan"> Zsolt Zalan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferenc%20Hegyi"> Ferenc Hegyi</a>, <a href="https://publications.waset.org/abstracts/search?q=Eniko%20Horvath-Szanics"> Eniko Horvath-Szanics</a>, <a href="https://publications.waset.org/abstracts/search?q=Krisztina%20Takacs"> Krisztina Takacs</a>, <a href="https://publications.waset.org/abstracts/search?q=Andras%20Nagy"> Andras Nagy</a>, <a href="https://publications.waset.org/abstracts/search?q=Adel%20Klupacs"> Adel Klupacs</a>, <a href="https://publications.waset.org/abstracts/search?q=Erika%20Koppany-Szabo"> Erika Koppany-Szabo</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhirong%20Wang"> Zhirong Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kaituo%20Wang"> Kaituo Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Muying%20Du"> Muying Du</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianquan%20Kan"> Jianquan Kan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The post-harvest diseases cause great economic losses in the fruit and vegetables; the prevention of these deterioration has great importance. Against the fungi, which cause most of the diseases, are extensively used the fungicides. However, there are increasing consumer concerns over the presence of pesticide residues in food. An alternative and in recent years, increasingly studied method for the prevention of the diseases is biocontrol, where antagonistic microorganisms are used for the control of fungi. The genera of Lactobacillus is well known and extensively studied, but its applicability as biocontrol agents in post-harvest preservation of fruit and vegetables is poorly investigated. However these bacteria can be found on the surface of the plants and have great antimicrobial activity. In our study we have investigated the chitinase activity, the antifungal effect and the applicability of several Lactobacillus strains to select potential biocontrol agents. We investigated the determination of the environmental parameters of a gene (encoding chitinase) expression and we also investigated the relationship between actual antifungal activity and potential chitinase activity. Mixed cultures were also developed to enhance the antifungal activity and determined the optimal mold spore and bacteria concentration ratio for the appropriate efficacy. Five Lactobacillus strains (L. acidophilus N2, L. delbrueckii subsp. bulgaricus B397, L. sp. 2231, L. sake subsp. sake 2471, L. buchneri 1145) possess chitinase-coding gene from the 43 investigated Lactobacillus strains. Proteins with similar molecular weight and separation properties like bacterial chitinases were detected from these strains, which also possess chitin-binding property. Nevertheless, they were inactive, lacks the chitinolytic activity. In point of the cumulative activity of inhibition, our results showed that certain strains were statistically significant in a positive direction compared to other strains, e.g., L. rhamnosus VT1 and L. Casey 154 have shown great general antifungal effect against 11 molds from the genera Penicillium and Botrytis and isolated from spoiled fruit and vegetables. Also, some mixed cultures (L. rhamnosus VT1 - L. Plantarum 299v) showed significant antifungal effects against the indigenous molds on the surface of apple fruit during the industrial storage experiment. Thus, they could be promising for post-harvest biopreservation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biocontrol" title="biocontrol">biocontrol</a>, <a href="https://publications.waset.org/abstracts/search?q=chitinase" title=" chitinase"> chitinase</a>, <a href="https://publications.waset.org/abstracts/search?q=Lactobacillus" title=" Lactobacillus"> Lactobacillus</a>, <a href="https://publications.waset.org/abstracts/search?q=post-harvest" title=" post-harvest"> post-harvest</a> </p> <a href="https://publications.waset.org/abstracts/121225/post-harvest-biopreservation-of-fruit-and-vegetables-with-application-of-lactobacillus-strains" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121225.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">154</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> The Intensity of Root and Soil Respiration Is Significantly Determined by the Organic Matter and Moisture Content of the Soil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20Kotrocz%C3%B3">Zsolt Kotroczó</a>, <a href="https://publications.waset.org/abstracts/search?q=Katalin%20Juhos"> Katalin Juhos</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%81ron%20B%C3%A9ni"> Áron Béni</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%A1bor%20V%C3%A1rb%C3%ADr%C3%B3"> Gábor Várbíró</a>, <a href="https://publications.waset.org/abstracts/search?q=Tam%C3%A1s%20Kocsis"> Tamás Kocsis</a>, <a href="https://publications.waset.org/abstracts/search?q=Istv%C3%A1n%20Fekete"> István Fekete</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Soil organic matter plays an extremely important role in the functioning and regulation processes of ecosystems. It follows that the C content of organic matter in soil is one of the most important indicators of soil fertility. Part of the carbon stored in them is returned to the atmosphere during soil respiration. Climate change and inappropriate land use can accelerate these processes. Our work aimed to determine how soil CO2 emissions change over ten years as a result of organic matter manipulation treatments. With the help of this, we were able to examine not only the effects of the different organic matter intake but also the effects of the different microclimates that occur as a result of the treatments. We carried out our investigations in the area of the Síkfőkút DIRT (Detritus Input and Removal Treatment) Project. The research area is located in the southern, hilly landscape of the Bükk Mountains, northeast of Eger (Hungary). GPS coordinates of the project: 47°55′34′′ N and 20°26′ 29′′ E, altitude 320-340 m. The soil of the area is Luvisols. The 27-hectare protected forest area is now under the supervision of the Bükki National Park. The experimental plots in Síkfőkút were established in 2000. We established six litter manipulation treatments each with three 7×7 m replicate plots established under complete canopy cover. There were two types of detritus addition treatments (Double Wood and Double Litter). In three treatments, detritus inputs were removed: No Litter No Roots plots, No Inputs, and the Controls. After the establishment of the plots, during the drier periods, the NR and NI treatments showed the highest CO2 emissions. In the first few years, the effect of this process was evident, because due to the lack of living vegetation, the amount of evapotranspiration on the NR and NI plots was much lower, and transpiration practically ceased on these plots. In the wetter periods, the NL and NI treatments showed the lowest soil respiration values, which were significantly lower compared to the Co, DW, and DL treatments. Due to the lower organic matter content and the lack of surface litter cover, the water storage capacity of these soils was significantly limited, therefore we measured the lowest average moisture content among the treatments after ten years. Soil respiration is significantly influenced by temperature values. Furthermore, the supply of nutrients to the soil microorganisms is also a determining factor, which in this case is influenced by the litter production dictated by the treatments. In the case of dry soils with a moisture content of less than 20% in the initial period, litter removal treatments showed a strong correlation with soil moisture (r=0.74). In very dry soils, a smaller increase in moisture does not cause a significant increase in soil respiration, while it does in a slightly higher moisture range. In wet soils, the temperature is the main regulating factor, above a certain moisture limit, water displaces soil air from the soil pores, which inhibits aerobic decomposition processes, and so heterotrophic soil respiration also declines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soil%20biology" title="soil biology">soil biology</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20matter" title=" organic matter"> organic matter</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrition" title=" nutrition"> nutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=DIRT" title=" DIRT"> DIRT</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20respiration" title=" soil respiration"> soil respiration</a> </p> <a href="https://publications.waset.org/abstracts/161546/the-intensity-of-root-and-soil-respiration-is-significantly-determined-by-the-organic-matter-and-moisture-content-of-the-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161546.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">75</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">3</span> Associations Between Pornography Use Motivations and Sexual Satisfaction in Gender Diverse and Cisgender Individuals in the 43-Country International Sex Survey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aur%C3%A9lie%20Michaud">Aurélie Michaud</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%89milie%20Gaudet"> Émilie Gaudet</a>, <a href="https://publications.waset.org/abstracts/search?q=M%C3%B3nika%20Ko%C3%B3s"> Mónika Koós</a>, <a href="https://publications.waset.org/abstracts/search?q=L%C3%A9na%20Nagy"> Léna Nagy</a>, <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20Demetrovics"> Zsolt Demetrovics</a>, <a href="https://publications.waset.org/abstracts/search?q=Shane%20W.%20Kraus"> Shane W.

Prior studies have assessed the associations between pornography use frequency and sexual satisfaction, in cisgender and heterosexual individuals, with mixed results. However, measuring pornography use solely by pornography use frequency is problematic, as it can lead to disregarding important contextual factors that may be related to pornography use’s potential effects. Pornography use motivations (PUMs) represent key predictors of sexual behaviors. Yet, their associations with different indicators of sexual wellbeing have yet to be extensively studied. This cross-cultural study examined the links between the eight PUMs most often reported in the general population (i.e. sexual pleasure, sexual curiosity, emotional distraction or suppression, fantasy, stress reduction, boredom avoidance, lack of sexual satisfaction, and self-exploration) and sexual satisfaction in gender diverse and cisgender individuals. Given the lack of scientific data on associations between individuals’ PUMs and sexual satisfaction, these links were examined in an exploratory manner. A total of 43 countries from five continents were included in the International Sex Survey (ISS). A secure online platform was used to collect self-report, anonymous data from 82,243 participants (39.6% men, 57% women, 3.4% gender diverse individuals; M = 32.4 years, SD = 12.5). Gender-based differences in levels of sexual pleasure, sexual curiosity, emotional distraction, fantasy, stress reduction, boredom avoidance, lack of sexual satisfaction, and self-exploration PUMs were examined using one-way ANOVAs. Then, for each gender group, the associations between each PUM and sexual satisfaction were examined using multiple linear regression, controlling for frequency of masturbation. One-way ANOVAs indicated significant differences between men, women, and gender diverse individuals on all PUMs. For sexual pleasure, sexual curiosity, fantasy, boredom avoidance, lack of sexual satisfaction, emotional distraction, and stress reduction PUMs, men showed the highest scores, followed by gender-diverse individuals, and women. However, for self-exploration, gender-diverse individuals had higher average scores than men. For all PUMs, women’s average scores were the lowest. After controlling for frequency of masturbation, for all genders, sexual pleasure, sexual curiosity and boredom avoidance were significant positive predictors of sexual satisfaction, while lack of sexual satisfaction PUM was a significant negative predictor. Fantasy, stress reduction and self-exploration PUMs were positive significant predictors of sexual satisfaction, and fantasy was a negative significant predictor, but only for women. Findings highlight important gender differences in regards to the main motivations underlying pornography use and their relations to sexual satisfaction. While men and gender diverse individuals show similar motivation profiles, woman report a particularly unique experience, with fantasy, stress reduction and self-exploration being associated to their sexual satisfaction. This work outlines the importance of considering the role of pornography use motivations when studying the links between pornography viewing and sexual well-being, and may provide basis for gender-based considerations when working with individuals seeking help for their pornography use or sexual satisfaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pornography" title="pornography">pornography</a>, <a href="https://publications.waset.org/abstracts/search?q=sexual%20satifsaction" title=" sexual satifsaction"> sexual satifsaction</a>, <a href="https://publications.waset.org/abstracts/search?q=cross-cultural" title=" cross-cultural"> cross-cultural</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20diversity" title=" gender diversity"> gender diversity</a> </p> <a href="https://publications.waset.org/abstracts/159509/associations-between-pornography-use-motivations-and-sexual-satisfaction-in-gender-diverse-and-cisgender-individuals-in-the-43-country-international-sex-survey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159509.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">106</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">2</span> Li2o Loss of Lithium Niobate Nanocrystals during High-Energy Ball-Milling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laura%20Kocsor">Laura Kocsor</a>, <a href="https://publications.waset.org/abstracts/search?q=Laszlo%20Peter"> Laszlo Peter</a>, <a href="https://publications.waset.org/abstracts/search?q=Laszlo%20Kovacs"> Laszlo Kovacs</a>, <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20Kis"> Zsolt Kis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of our research is to prepare rare-earth-doped lithium niobate (LiNbO3) nanocrystals, having only a few dopant ions in the focal point of an exciting laser beam. These samples will be used to achieve individual addressing of the dopant ions by light beams in a confocal microscope setup. One method for the preparation of nanocrystalline materials is to reduce the particle size by mechanical grinding. High-energy ball-milling was used in several works to produce nano lithium niobate. Previously, it was reported that dry high-energy ball-milling of lithium niobate in a shaker mill results in the partial reduction of the material, which leads to a balanced formation of bipolarons and polarons yielding gray color together with oxygen release and Li2O segregation on the open surfaces. In the present work we focus on preparing LiNbO3 nanocrystals by high-energy ball-milling using a Fritsch Pulverisette 7 planetary mill. Every ball-milling process was carried out in zirconia vial with zirconia balls of different sizes (from 3 mm to 0.1 mm), wet grinding with water, and the grinding time being less than an hour. Gradually decreasing the ball size to 0.1 mm, an average particle size of about 10 nm could be obtained determined by dynamic light scattering and verified by scanning electron microscopy. High-energy ball-milling resulted in sample darkening evidenced by optical absorption spectroscopy measurements indicating that the material underwent partial reduction. The unwanted lithium oxide loss decreases the Li/Nb ratio in the crystal, strongly influencing the spectroscopic properties of lithium niobate. Zirconia contamination was found in ground samples proved by energy-dispersive X-ray spectroscopy measurements; however, it cannot be explained based on the hardness properties of the materials involved in the ball-milling process. It can be understood taking into account the presence of lithium hydroxide formed the segregated lithium oxide and water during the ball-milling process, through chemically induced abrasion. The quantity of the segregated Li2O was measured by coulometric titration. During the wet milling process in the planetary mill, it was found that the lithium oxide loss increases linearly in the early phase of the milling process, then a saturation of the Li2O loss can be seen. This change goes along with the disappearance of the relatively large particles until a relatively narrow size distribution is achieved in accord with the dynamic light scattering measurements. With the 3 mm ball size and 1100 rpm rotation rate, the mean particle size achieved is 100 nm, and the total Li2O loss is about 1.2 wt.% of the original LiNbO3. Further investigations have been done to minimize the Li2O segregation during the ball-milling process. Since the Li2O loss was observed to increase with the growing total surface of the particles, the influence of ball-milling parameters on its quantity has also been studied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high-energy%20ball-milling" title="high-energy ball-milling">high-energy ball-milling</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium%20niobate" title=" lithium niobate"> lithium niobate</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanochemical%20reaction" title=" mechanochemical reaction"> mechanochemical reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocrystals" title=" nanocrystals"> nanocrystals</a> </p> <a href="https://publications.waset.org/abstracts/136642/li2o-loss-of-lithium-niobate-nanocrystals-during-high-energy-ball-milling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136642.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">135</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> PARP1 Links Transcription of a Subset of RBL2-Dependent Genes with Cell Cycle Progression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ewelina%20Wisnik">Ewelina Wisnik</a>, <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20Regdon"> Zsolt Regdon</a>, <a href="https://publications.waset.org/abstracts/search?q=Kinga%20Chmielewska"> Kinga Chmielewska</a>, <a href="https://publications.waset.org/abstracts/search?q=Laszlo%20Virag"> Laszlo Virag</a>, <a href="https://publications.waset.org/abstracts/search?q=Agnieszka%20Robaszkiewicz"> Agnieszka Robaszkiewicz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Apart from protecting genome, PARP1 has been documented to regulate many intracellular processes inter alia gene transcription by physically interacting with chromatin bound proteins and by their ADP-ribosylation. Our recent findings indicate that expression of PARP1 decreases during the differentiation of human CD34+ hematopoietic stem cells to monocytes as a consequence of differentiation-associated cell growth arrest and formation of E2F4-RBL2-HDAC1-SWI/SNF repressive complex at the promoter of this gene. Since the RBL2 complexes repress genes in a E2F-dependent manner and are widespread in the genome in G0 arrested cells, we asked (a) if RBL2 directly contributes to defining monocyte phenotype and function by targeting gene promoters and (b) if RBL2 controls gene transcription indirectly by repressing PARP1. For identification of genes controlled by RBL2 and/or PARP1,we used primer libraries for surface receptors and TLR signaling mediators, genes were silenced by siRNA or shRNA, analysis of gene promoter occupation by selected proteins was carried out by ChIP-qPCR, while statistical analysis in GraphPad Prism 5 and STATISTICA, ChIP-Seq data were analysed in Galaxy 2.5.0.0. On the list of 28 genes regulated by RBL2, we identified only four solely repressed by RBL2-E2F4-HDAC1-BRM complex. Surprisingly, 24 out of 28 emerged genes controlled by RBL2 were co-regulated by PARP1 in six different manners. In one mode of RBL2/PARP1 co-operation, represented by MAP2K6 and MAPK3, PARP1 was found to associate with gene promoters upon RBL2 silencing, which was previously shown to restore PARP1 expression in monocytes. PARP1 effect on gene transcription was observed only in the presence of active EP300, which acetylated gene promoters and activated transcription. Further analysis revealed that PARP1 binding to MA2K6 and MAPK3 promoters enabled recruitment of EP300 in monocytes, while in proliferating cancer cell lines, which actively transcribe PARP1, this protein maintained EP300 at the promoters of MA2K6 and MAPK3. Genome-wide analysis revealed a similar distribution of PARP1 and EP300 around transcription start sites and the co-occupancy of some gene promoters by PARP1 and EP300 in cancer cells. Here, we described a new RBL2/PARP1/EP300 axis which controls gene transcription regardless of the cell type. In this model cell, cycle-dependent transcription of PARP1 regulates expression of some genes repressed by RBL2 upon cell cycle limitation. Thus, RBL2 may indirectly regulate transcription of some genes by controlling the expression of EP300-recruiting PARP1.
