For instance, in order to crack the catalyses in petrochemical industries or as a drier in food industries. High capacity of fluidized bed in heat and mass transfer has made this device very popular. In order to achieve a higher efficiency of fluidized beds, a particular attention has been paid to beds with pulsating air flow. In this paper, a fluidized bed device with pulsating flow has been designed and constructed. Size of particles have been used during the test are in the range of 40 to 100μm. The purpose of this experimental test is to investigate the air flow regime, observe the particles- movement and measure the pressure loss along the bed. The effects of pulsation can be evaluated by comparing the results for both continuous and pulsating flow. Results of both situations are compared for various gas speeds. Moreover the above experiment is numerically simulated by using Fluent software and its numerical results are compared with the experimental results.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Fluidized%20bed" title="Fluidized bed">Fluidized bed</a>, <a href="https://publications.waset.org/search?q=pulsating%20flow" title=" pulsating flow"> pulsating flow</a>, <a href="https://publications.waset.org/search?q=gas-solid%20particles" title=" gas-solid particles"> gas-solid particles</a>, <a href="https://publications.waset.org/search?q=pressure%20loss" title=" pressure loss"> pressure loss</a>, <a href="https://publications.waset.org/search?q=experiments" title=" experiments"> experiments</a>, <a href="https://publications.waset.org/search?q=Fluent." title=" Fluent."> Fluent.</a> </p> <a href="https://publications.waset.org/7532/an-experimental-study-on-effects-of-applying-the-pulsating-flow-to-a-gas-solid-fluidized-bed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/7532/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/7532/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/7532/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/7532/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/7532/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/7532/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/7532/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/7532/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/7532/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/7532/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/7532.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">2072</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Influence of Bentonite Additive on Bitumen and Asphalt Mixture Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Ziari%20Hassan">Ziari Hassan</a>, <a href="https://publications.waset.org/search?q=Divandari%20Hassan"> Divandari Hassan</a>, <a href="https://publications.waset.org/search?q=Babagoli%20Rezvan"> Babagoli Rezvan</a>, <a href="https://publications.waset.org/search?q=Akbari%20Ali"> Akbari Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Asphalt surfaces are exposed to various weather conditions and dynamic loading caused by passing trucks and vehicles. In such situations, asphalt cement shows so different rheological-mechanical behavior. If asphalt cement isn-t compatible enough, asphalt layer will be damaged immediately and expensive repairing procedures should be performed then. To overcome this problem, researchers study on mechanical improved asphalt cement. In this study, bentonite was used in order to modify bitumen characteristics and the modified bitumen's characteristics were investigated by asphalt cement tests. Then, the optimal bitumen content in various compounds was determined and asphalt samples with different contents of additives were prepared and tested. Results show using this kind of additive not only has caused improvement in bitumen mechanical properties, but also improvement in Marshall Parameters was achieved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Asphalt%20mixture" title="Asphalt mixture">Asphalt mixture</a>, <a href="https://publications.waset.org/search?q=Bentonite" title=" Bentonite"> Bentonite</a>, <a href="https://publications.waset.org/search?q=Modified%20bitumen" title=" Modified bitumen"> Modified bitumen</a>, <a href="https://publications.waset.org/search?q=Performance%20characteristics" title=" Performance characteristics"> Performance characteristics</a> </p> <a href="https://publications.waset.org/10846/influence-of-bentonite-additive-on-bitumen-and-asphalt-mixture-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10846/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10846/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10846/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10846/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10846/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10846/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10846/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10846/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10846/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10846/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10846.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">3899</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> miR-200c as a Biomarker for 5-FU Chemosensitivity in Colorectal Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Rezvan%20Najafi">Rezvan Najafi</a>, <a href="https://publications.waset.org/search?q=Korosh%20Heydari"> Korosh Heydari</a>, <a href="https://publications.waset.org/search?q=Massoud%20Saidijam"> Massoud Saidijam </a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>5-FU is a chemotherapeutic agent that has been used in colorectal cancer (CRC) treatment. However, it is usually associated with the acquired resistance, which decreases the therapeutic effects of 5-FU. miR-200c is involved in chemotherapeutic drug resistance, but its mechanism is not fully understood. In this study, the effect of inhibition of miR-200c in sensitivity of HCT-116 CRC cells to 5-FU was evaluated. HCT-116 cells were transfected with LNA-anti- miR-200c for 48 h. mRNA expression of miR-200c was evaluated using quantitative real- time PCR. The protein expression of phosphatase and tensin homolog (PTEN) and E-cadherin were analyzed by western blotting. Annexin V and propidium iodide staining assay were applied for <em>apoptosis detection. </em>The caspase-3 activation was evaluated by an enzymatic assay. The results showed LNA-anti-miR-200c inhibited the expression of PTEN and E-cadherin protein, apoptosis and activation of caspase 3 compared with control cells. In conclusion, these results suggest that miR-200c as a prognostic marker can overcome to 5-FU chemoresistance in CRC.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Colorectal%20cancer" title="Colorectal cancer">Colorectal cancer</a>, <a href="https://publications.waset.org/search?q=miR-200c" title=" miR-200c"> miR-200c</a>, <a href="https://publications.waset.org/search?q=5-FU%20resistance" title=" 5-FU resistance"> 5-FU resistance</a>, <a href="https://publications.waset.org/search?q=E-cadherin" title=" E-cadherin"> E-cadherin</a>, <a href="https://publications.waset.org/search?q=PTEN." title=" PTEN.
