The objective of this paper is to give an overview of the flotation of chalcopyrite with the different conditions and dispersants. Flotation parameters such as grinding time, pH, type, and dosage of dispersant were investigated. In order to understand the interaction of some dispersants, sodium silicate, sodium hexametaphosphate and sodium polyphosphate were used. The optimum results were obtained at a pH of 11.5 and a grinding time of 10 minutes. A copper concentrate was produced assaying 29.85% CuFeS<sub>2</sub> and 65.97% flotation recovery under optimum rougher ﬂotation conditions with sodium silicate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chalcopyrite" title="chalcopyrite">chalcopyrite</a>, <a href="https://publications.waset.org/abstracts/search?q=dispersant" title=" dispersant"> dispersant</a>, <a href="https://publications.waset.org/abstracts/search?q=flotation" title=" flotation"> flotation</a>, <a href="https://publications.waset.org/abstracts/search?q=reagent" title=" reagent"> reagent</a> </p> <a href="https://publications.waset.org/abstracts/91056/investigation-of-some-flotation-parameters-and-the-role-of-dispersants-in-the-flotation-of-chalcopyrite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91056.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">182</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> Effect of Amine-Functionalized Carbon Nanotubes on the Properties of CNT-PAN Composite Nanofibers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20Eren">O.

In this study, the effect of exfoliation time and presence of activated carbon particle (ACP) on graphene oxide fiber’s properties has been analyzed. It has been seen that cross-sectional appearance of sample with ACP is harsh and porous because of ACP. The addition of ACP did not change the electrical conductivity. However, ACP results in an enormous decrease of mechanical properties. Longer exfoliation time results to higher crystallinity degree, C/O ratio and less d space between layers. The breaking strength and electrical conductivity of sample with less exfoliation time is some higher than sample with high exfoliation time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon" title="activated carbon">activated carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=coagulation%20by%20wet%20spinning" title=" coagulation by wet spinning"> coagulation by wet spinning</a>, <a href="https://publications.waset.org/abstracts/search?q=exfoliation" title=" exfoliation"> exfoliation</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene%20oxide%20fiber" title=" graphene oxide fiber"> graphene oxide fiber</a> </p> <a href="https://publications.waset.org/abstracts/64936/graphene-oxide-fiber-with-different-exfoliation-time-and-activated-carbon-particle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64936.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">343</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> The Effect of Fly Ash in Dewatering of Marble Processing Wastewaters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20A.%20Taner">H.

However, fly ash can find evaluation opportunities in various sectors. In this study, the effectiveness of fly ash on suspended solid removal from marble processing wastewater containing high concentration of suspended solids was examined. Experiments were carried out for two different suspensions, marble and travertine. In the experiments, FeCl<sub>3</sub>, Al<sub>2</sub>(SO<sub>4</sub>)<sub>3</sub> and anionic polymer A130 were used also to compare with fly ash. Coagulant/flocculant type/dosage, mixing time/speed and pH were the experimental parameters. The performances in the experimental studies were assessed with the change in the interface height during sedimentation resultant and turbidity values of treated water. The highest sedimentation efficiency was achieved with anionic flocculant. However, it was determined that fly ash can be used instead of FeCl<sub>3</sub> and Al<sub>2</sub>(SO<sub>4</sub>)<sub>3 </sub>in the travertine plant as a coagulant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dewatering" title="dewatering">dewatering</a>, <a href="https://publications.waset.org/abstracts/search?q=flocculant" title=" flocculant"> flocculant</a>, <a href="https://publications.waset.org/abstracts/search?q=fly%20ash" title=" fly ash"> fly ash</a>, <a href="https://publications.waset.org/abstracts/search?q=marble%20plant%20wastewater" title=" marble plant wastewater"> marble plant wastewater</a> </p> <a href="https://publications.waset.org/abstracts/91052/the-effect-of-fly-ash-in-dewatering-of-marble-processing-wastewaters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91052.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">152</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 Validity of Integrating the Concept of Servant Leadership in the Discourse of Poverty Eradication</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ocen%20Walter%20Onen">Ocen Walter Onen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In 2018, the World Bank reported that approximately 8.6% of the global population was languishing in multidimensional poverty. This reality both challenged and motivated the research on the topic above. This research critically examined the validity of integrating the concept of servant leadership into the discourse of poverty eradication. The researcher applied documentary research methodology. Therefore, relevant literature, both printed and electronic, was analyzed, and desired data were obtained to enrich the discussion. The main finding from the research shows that; the concept of ‘servant leadership’, despite being paradoxical in nature, has the necessary potential to accelerate the effort of eliminating multidimensional poverty in any given context. Based on that, the researcher recommended that; state-actors, multi-national corporations, development organizations such as the United Nations, and other agencies working to make poverty history in our generation should both prioritize and promotes the integration of the concept of servant leadership in their policies’ formation, organizational leadership and management, and project design, implementation and evaluation of poverty-eradication initiatives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multidimensional%20poverty" title="multidimensional poverty">multidimensional poverty</a>, <a href="https://publications.waset.org/abstracts/search?q=poverty%20eradication" title=" poverty eradication"> poverty eradication</a>, <a href="https://publications.waset.org/abstracts/search?q=servant%20leadership" title=" servant leadership"> servant leadership</a>, <a href="https://publications.waset.org/abstracts/search?q=United%20Nations" title=" United Nations"> United Nations</a> </p> <a href="https://publications.waset.org/abstracts/159839/the-validity-of-integrating-the-concept-of-servant-leadership-in-the-discourse-of-poverty-eradication" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159839.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">80</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> Investigation of Electrical, Thermal and Structural Properties on Polyacrylonitrile Nano-Fiber</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Demirsoy">N.

Silver nano-particles were obtained from reduction of silver ions into silver nano-particles by chemical reduction by hydrazine hydroxide (N2H5OH). The different amount of silver salt was loaded into polymer matrix to obtain polyacrylonitrile composite nano-fiber containing silver nano-particles. The effect of the amount of silver nano-particles on the properties of composite nano-fiber web was investigated. Electrical conductivity, mechanical properties, thermal properties were examined by Microtest LCR Meter 6370 (0.01 mΩ-100 MΩ), tensile tester, differential scanning calorimeter DSC (Q10) and SEM, respectively. Also, antimicrobial efficiency test (ASTM E2149-10) was done against Staphylococcus aureus bacteria.

Thus, the capture of SO<sub>2</sub> gas is very important for the environment. Graphene which is two-dimensional material has excellent mechanical, chemical, thermal properties, and many application areas such as energy storage devices, gas adsorption, sensing devices, and optical electronics. Further, graphene oxide (GO) is examined as a good adsorbent because of its important features such as functional groups (epoxy, carboxyl and hydroxyl) on the surface and layered structure. The SO<sub>2</sub> adsorption properties of the fibers are usually investigated on carbon fibers. In this study, potential adsorption capacity of GO fibers was researched. GO dispersion was first obtained with Hummers’ method from graphite, and then GO fibers were obtained via wet spinning process. These fibers were converted into a disc shape, dried, and then subjected to SO<sub>2</sub> gas adsorption test. The SO<sub>2</sub> gas adsorption capacity of GO fiber discs was investigated in the fields of utilization of different coagulation baths and reduction by hydrazine hydrate. As coagulation baths, single and triple baths were used. In single bath, only ethanol and CaCl<sub>2</sub> (calcium chloride) salt were added. In triple bath, each bath has a different concentration of water/ethanol and CaCl<sub>2</sub> salt, and the disc obtained from triple bath has been called as reference disk. The fibers which were produced with single bath were flexible and rough, and the analyses show that they had higher SO<sub>2</sub> adsorption capacity than triple bath fibers (reference disk). However, the reduction process did not increase the adsorption capacity, because the SEM images showed that the layers and uniform structure in the fiber form were damaged, and reduction decreased the functional groups which SO<sub>2</sub> will be attached. Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD) analyzes were performed on the fibers and discs, and the effects on the results were interpreted. In the future applications of the study, it is aimed that subjects such as pH and additives will be examined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coagulation%20bath" title="coagulation bath">coagulation bath</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene%20oxide%20fiber" title=" graphene oxide fiber"> graphene oxide fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=reduction" title=" reduction"> reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=SO2%20gas%20adsorption" title=" SO2 gas adsorption"> SO2 gas adsorption</a> </p> <a href="https://publications.waset.org/abstracts/68831/effects-of-the-coagulation-bath-and-reduction-process-on-so2-adsorption-capacity-of-graphene-oxide-fiber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68831.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">360</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> Gains and Pitfalls of Participating on International Staff Exchange Programs: Individual Experiences of Academic Staff of Makerere University, Uganda</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20Onen">David Onen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Staff exchanges amongst different work organizations are a growing international phenomenon. In higher education in particular, it is not only the staff participating on international exchange programs, but their students as well. The practice of exchanging staff is premised on the belief that participating members of staff would not only get the chance to network with colleagues from partner institutions but also gain the opportunity for knowledge sharing and skills development. As a result, it would not only benefit the participating individual staff but their institutions too. However, in practice, staff exchange programs everywhere are not all ‘a bed of roses’. In fact, some of the programs seem to be laden with unapparent source of trouble or danger for the participating staff. This paper is a report on an on-going study investigating the experiences of members of academic staff of Makerere University in Uganda who have ever participated on international staff exchange programs. The study is aimed at documenting individual experiences in order to stimulate, not only a debate, but practical ways of enriching the experiences of staff who engage on well-meant international staff exchange programs. The study has employed an exploratory survey research design in which self-administered questionnaire and interview guide are being used to collect data from university academic staff respondents selected through snow-ball and purposive sampling techniques. Data have been analysed with the use of appropriate descriptive and inferential statistics as well as content analysis techniques. Preliminary study findings reveal that the majority of the respondents (95.5%) were, to a large extent, fully satisfied with their participation on the staff exchange programs. Many attested to gaining new experience (97%), networking (75%), gaining new knowledge (94%), acquiring new skills (88%), and therefore bringing to their institutions something ‘new’ and ‘beneficial’. However, a reasonably large percentage (57%) of the participants too expressed dissatisfaction in the institutional support that Makerere University gave them during their participation on the exchange programs. Some respondents reported about the ‘unfriendly welcome’ they received upon returning ‘home’ because colleagues detested how they were chosen to participate on such programs. The researcher thus concluded that international staff exchange programs are truly beneficial to both the participating staff and their institutions though with pitfalls. The researcher thus recommended for mutual and preferably equal engagement of the participating institutions on staff exchange programs if such programs are to benefit both the participating staff and institutions. Besides, exchange programs require clear terms of cooperation including on how staff are selected, facilitated and what are expected of the sending and host institutions as well as the concerned staff. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gains" title="gains">gains</a>, <a href="https://publications.waset.org/abstracts/search?q=exchange%20programs" title=" exchange programs"> exchange programs</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title=" higher education"> higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=pitfalls" title=" pitfalls"> pitfalls</a> </p> <a href="https://publications.waset.org/abstracts/34944/gains-and-pitfalls-of-participating-on-international-staff-exchange-programs-individual-experiences-of-academic-staff-of-makerere-university-uganda" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34944.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">344</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">© 2024 World Academy of Science, Engineering and Technology</div> </div> </footer> <a href="javascript:" id="return-to-top"><i class="fas fa-arrow-up"></i></a> <div class="modal" id="modal-template"> <div class="modal-dialog"> <div class="modal-content"> <div class="row m-0 mt-1"> <div class="col-md-12"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> </div> </div> <div class="modal-body"></div> </div> </div> </div> <script src="https://cdn.waset.org/static/plugins/jquery-3.3.1.min.js"></script> <script src="https://cdn.waset.org/static/plugins/bootstrap-4.2.1/js/bootstrap.bundle.min.js"></script> <script src="https://cdn.waset.org/static/js/site.js?v=150220211556"></script> <script> jQuery(document).ready(function() { /*jQuery.get("https://publications.waset.org/xhr/user-menu", function (response) { jQuery('#mainNavMenu').append(response);
