affecting the agricultural production worldwide. In this study, Leaf samples were taken from the carrot plants grown under drought stress conditions during the harvesting period. The plants were irrigated in three irrigation interval (4, 6 and 8 days) and Irrigation water regime was set up in pots. The changes in activities of antioxidant enzymes such as glutathione reductase (GR), glutathione s-transferase (GST), superoxide dismutase (SOD)) in leaves of black carrot were investigated. The activities of antioxidant enzymes (GR, GST, SOD) were varied significantly with irrigation intervals. The highest value of GR, GST and SOD were determined in the irrigation interval of 6 days. All antioxidant activity values were decreased in 8 days of irrigation interval. As a result of the study, it has been suggested that optimum irrigation intervals for plants can be used in antioxidant enzymes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20enzyme" title="antioxidant enzyme">antioxidant enzyme</a>, <a href="https://publications.waset.org/abstracts/search?q=carrot" title=" carrot"> carrot</a>, <a href="https://publications.waset.org/abstracts/search?q=drought" title=" drought"> drought</a>, <a href="https://publications.waset.org/abstracts/search?q=irrigation%20interval" title=" irrigation interval"> irrigation interval</a> </p> <a href="https://publications.waset.org/abstracts/96989/effects-of-irrigation-intervals-on-antioxidant-enzyme-activity-in-black-carrot-leaves-daucus-carota-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96989.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">221</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">52</span> Determination of the Inhibitory Effects of N-Methylpyrrole Derivatives on Glutathione Reductase Enzyme</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Esma%20Kocaoglu">Esma Kocaoglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Oktay%20Talaz"> Oktay Talaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Huseyin%20Cavdar"> Huseyin Cavdar</a>, <a href="https://publications.waset.org/abstracts/search?q=Murat%20Senturk"> Murat Senturk</a>, <a href="https://publications.waset.org/abstracts/search?q=Deniz%20Eki%CC%87nci%CC%87"> Deniz Eki̇nci̇</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Glutathione reductase (GR) is a crucial antioxidant enzyme which is responsible for the maintenance of the antioxidant GSH (glutathione) molecule. Antimalarial effects of some chemical molecules are attributed to their inhibition of GR; thus inhibitors of this enzyme are expected to be promising candidates for the treatment of malaria. In this work, GR inhibitory properties of N-Methylpyrrole derivatives are reported. Firstly, GR was purified by means of affinity chromatography using 2’,5’-ADP-Sepharose 4B as ligand. Enzymatic activity was measured by Beutler’s method. Synthesis of the compounds was approved by thin layer chromatography and column chromatography. Different inhibitor concentrations were used and all compounds were tested in triplicate at each concentration used. It was found that all compounds have better inhibitory activity than the strong GR inhibitor N,N-bis(2-chloroethyl)-N-nitrosourea, especially three molecules, 8m, 8n, and 8q, are the best among them with low micromolar I₅₀ values. Findings of our study indicate that these Schiff base derivatives are strong GR inhibitors which can be used as leads for designation of novel antimalaria candidates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glutathione%20reductase" title="glutathione reductase">glutathione reductase</a>, <a href="https://publications.waset.org/abstracts/search?q=antimalaria" title=" antimalaria"> antimalaria</a>, <a href="https://publications.waset.org/abstracts/search?q=inhibitor" title=" inhibitor"> inhibitor</a>, <a href="https://publications.waset.org/abstracts/search?q=enzyme" title=" enzyme"> enzyme</a> </p> <a href="https://publications.waset.org/abstracts/96801/determination-of-the-inhibitory-effects-of-n-methylpyrrole-derivatives-on-glutathione-reductase-enzyme" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96801.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">270</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">51</span> A Review on the Comparison of EU Countries Based on Research and Development Efficiencies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yeliz%20Ekinci">Yeliz Ekinci</a>, <a href="https://publications.waset.org/abstracts/search?q=Raife%20Merve%20%C3%96n"> Raife Merve Ön</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, technological progress is one of the most important components of economic growth and the efficiency of R&D activities is particularly essential for countries.

Hydrophobic silica aerogels were successfully synthesized in one-step by surface modification at ambient pressure. FT-IR result confirmed that Si-OH groups were successfully converted into hydrophobic and non-polar Si-CH3 groups by surface modification using trimethylchloro silane (TMCS) as co-precursor. Using Alpha-A High-Resolution Dielectric, Conductivity and Impedance Analyzer, AC conductivity of samples were examined at temperature range 293-423 K and measured over frequency range between 1-106 Hz. The characteristic relaxation time decreases with increasing temperature. The AC conductivity follows σ_AC (ω)=σ_t-σ_DC=Aω^s relation at frequencies higher than 10 Hz, and the dominant conduction mechanism is found to obey the Correlated Barrier Hopping (CBH) mechanism. At frequencies lower than 10 Hz, the electrical conduction is found to be in accordance with DC conduction mechanism. The activation energies obtained from AC conductivity results and it was observed two relaxation regions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerogel" title="aerogel">aerogel</a>, <a href="https://publications.waset.org/abstracts/search?q=synthesis" title=" synthesis"> synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=dielectric%20constant" title=" dielectric constant"> dielectric constant</a>, <a href="https://publications.waset.org/abstracts/search?q=dielectric%20loss" title=" dielectric loss"> dielectric loss</a>, <a href="https://publications.waset.org/abstracts/search?q=relaxation%20time" title=" relaxation time"> relaxation time</a> </p> <a href="https://publications.waset.org/abstracts/92943/dielectric-spectroscopy-investigation-of-hydrophobic-silica-aerogel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92943.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">190</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> Dielectric Properties of Thalium Selenide Thin Films at Radio Wave Frequencies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Onur%20Potok">Onur Potok</a>, <a href="https://publications.waset.org/abstracts/search?q=Deniz%20Deger"> Deniz Deger</a>, <a href="https://publications.waset.org/abstracts/search?q=Kemal%20Ulutas"> Kemal Ulutas</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahin%20Yakut"> Sahin Yakut</a>, <a href="https://publications.waset.org/abstracts/search?q=Deniz%20Bozoglu"> Deniz Bozoglu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Thalium Selenide (TlSe) is used for optoelectronic devices, pressure sensitive detectors, and gamma-ray detectors. The TlSe samples were grown as large single crystals using the Stockbarger-Bridgman method. The thin films, in the form of Al/TlSe/Al, were deposited on the microscope slide in different thicknesses (300-3000 Å) using thermal evaporation technique at 10-5 Torr. The dielectric properties of (TlSe) thin films, capacitance (C) and dielectric loss factor (tanδ), were measured in a frequency range of 10-105 Hz, and temperatures between 213K and 393K via Broadband Dielectric Spectroscopy analyzer. The dielectric constant (ε’) and the dielectric loss (ε’’) of the thin films were derived from measured parameters (C and tanδ). These results showed that the dielectric properties of TlSe thin films are frequency and temperature dependent. The capacitance and the dielectric constant decrease with increasing frequency and decreasing temperature. The dielectric loss of TlSe thin films decreases with increasing frequency, on the other hand, they increase with increasing temperature and increasing thicknesses. There is two relaxation region in the investigated frequency and temperature interval. These regions can be called as low and high-frequency dispersion regions. Low-frequency dispersion region can be attributed to the polarization of the main part of the chain structure of TlSe while high-frequency dispersion region can be attributed to the polarization of side parts of the structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thin%20films" title="thin films">thin films</a>, <a href="https://publications.waset.org/abstracts/search?q=thallium%20selenide" title=" thallium selenide"> thallium selenide</a>, <a href="https://publications.waset.org/abstracts/search?q=dielectric%20spectroscopy" title=" dielectric spectroscopy"> dielectric spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=binary%20compounds" title=" binary compounds"> binary compounds</a> </p> <a href="https://publications.waset.org/abstracts/92950/dielectric-properties-of-thalium-selenide-thin-films-at-radio-wave-frequencies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92950.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">153</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">48</span> Investigation of VN/TiN Multilayer Coatings on AZ91D Mg Alloys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Ertas">M.

Waste management planning can protect the environment and human health, hence it is tremendously important for countries. The lack of information in waste generation can cause many environmental and health problems. Turkey is a country that plans to join European Union, hence, solid waste management is one of the most significant criteria that should be handled in order to be a part of this community. Solid waste management system requires a good forecast of solid waste generation. Thus, this study aims to forecast solid waste generation in Turkey. Artificial Neural Network and Linear Regression models will be used for this aim.

In another word, the power to enact decrees, appoint bureaucrats and judicial officials into offices, and the power to dissolve a parliament belongs solely to the president. As a strong presidency fuse with a disciplined party system as well as concurrent elections and 10 percent electoral threshold, the president possibly poses a great danger to the separation of powers. Additionally, with regards to the presidential term, the president constitutionally holds the power to be elected only for two terms in Turkey. However, Erdoğan and his supporters believe that the 2017 constitutional amendments that changed the system of government have reset the agenda.

Nanoparticles (NPs) can be prepared from a variety of materials such as lipid, biodegradable polymer that prevent the drugs cytotoxicity in healthy cells, etc. One of the most important drugs used in chemotherapy is mitoxantrone (MTX) which prevents cell proliferation by inhibition of topoisomerase II and DNA repair; however, it is not selective and has some serious side effects. In this study, mentioned aim is achieved by using several nanocarriers like magnetite (Fe3O4) and their composites with magnetic graphene oxide (Fe3O4@GO). Also, cytotoxic potential of Fe3O4, Fe3O4-MTX, and Fe3O4@GO-MTX nanocomposite were evaluated on mesenchymal stem cells (MSCs). In this study, we reported the synthesis of monodisperse Fe3O4 NPs and Fe3O4@GO nanocomposite and their structures were investigated by using field emission scanning electron microscope (FESEM), Fourier transform infrared (FTIR) spectra, atomic force microscopy (AFM), Brauneur Emmet Teller (BET) isotherm and contact angle studies. Moreover, we used 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay to evaluate cytotoxic effects of MTX, Fe3O4 NPs, Fe3O4-MTX and Fe3O4@GO-MTX nanocomposite on MSCs. The in-vitro MTT results indicated that all concentrations of MTX and Fe3O4@GO-MTX nanocomposites showed cytotoxic effects while all concentrations of Fe3O4 NPs and Fe3O4-MTX NPs did not show any cytotoxic effect on stem cells. The results from this study indicated that using Fe3O4 NPs as anticancer drug delivery systems could be a trustworthy method for cancer treatment. But for reaching excellent and accurate results, further investigation is necessary. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mitoxantrone" title="mitoxantrone">mitoxantrone</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetite" title=" magnetite"> magnetite</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20graphene%20oxide" title=" magnetic graphene oxide"> magnetic graphene oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=MTT%20assay" title=" MTT assay"> MTT assay</a>, <a href="https://publications.waset.org/abstracts/search?q=mesenchymal%20stem%20cells" title=" mesenchymal stem cells"> mesenchymal stem cells</a> </p> <a href="https://publications.waset.org/abstracts/66115/evaluation-of-cytotoxic-effect-of-mitoxantrone-conjugated-magnetite-nanoparticles-and-graphene-oxide-magnetite-nanocomposites-on-mesenchymal-stem-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66115.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">272</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> Analyzing the Relationship between the Spatial Characteristics of Cultural Structure, Activities, and the Tourism Demand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Deniz%20Karag%C3%B6z">Deniz Karagöz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is attempt to comprehend the relationship between the spatial characteristics of cultural structure, activities and the tourism demand in Turkey.

A number of specialized technologies including precipitation, coagulation/flocculation, ion exchange, cementation, electrochemical operations, have been developed for the removal of heavy metals from wastewater. However, these technologies have many limitations in the application, such as high cost, low separation efficiency, Recently, numerous approaches have been investigated to overcome these difficulties and membrane filtration, advanced oxidation technologies (AOPs), and UV irradiation etc. are sufficiently developed to be considered as alternative treatments. Many factors come into play when selecting wastewater treatment technology, such as type of wastewater, operating conditions, economics etc. This study describes these various treatment technologies employed for heavy metal removal. Advantages and disadvantages of these technologies are also compared to highlight their current limitations and future research needs. For example, we investigated the applicability of the ultraﬁltration technology for treating of heavy metal ions (e.g., Cu(II), Pb(II), Cd(II), Zn(II)) from synthetic wastewater solutions. Results shown that complete removal of metal ions, could be achieved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heavy%20metal" title="heavy metal">heavy metal</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment%20methodologies" title=" treatment methodologies"> treatment methodologies</a>, <a href="https://publications.waset.org/abstracts/search?q=water" title=" water"> water</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20treatment" title=" water treatment"> water treatment</a> </p> <a href="https://publications.waset.org/abstracts/97580/a-review-of-recent-studies-on-advanced-technologies-for-water-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97580.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">170</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Reducing the Urban Heat Island Effect by Urban Design Strategies: Case Study of Aksaray Square in Istanbul</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Busra%20Ekinci">Busra Ekinci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Urban heat island term becomes one of the most important problem in urban areas as a reflection of global warming in local scale last years. Many communities and governments are taking action to reduce heat island effects on urban areas where the half of the world's population live today. At this point, urban design turned out to be an important practice and research area for providing an environmentally sensitive urban development. In this study, mitigating strategies of urban heat island effects by urban design are investigated in Aksaray Square and surroundings in Istanbul. Aksaray is an important historical and commercial center of Istanbul, which has an increasing density due to be the node of urban transportation. Also, Istanbul Metropolitan Municipality prepared an urban design project to respond the needs of growing population in the area for 2018. The purpose of the study is emphasizing the importance of urban design objectives and strategies that are developed to reduce the heat island effects on urban areas. Depending on this, the urban heat island effect of the area was examined based on the albedo (reflectivity) parameter which is the most effective parameter in the formation of the heat island effect in urban areas. Albedo values were calculated by Albedo Viewer web application model that was developed by Energy and Environmental Engineering Department of Kyushu University in Japan. Albedo parameter had examined for the present situation and the planned situation with urban design project. The results show that, the current area has urban heat island potential. With the Aksaray Square Project, the heat island effect on the area can be reduced, but would not be completely prevented. Therefore, urban design strategies had been developed to reduce the island effect in addition to the urban design project of the area. This study proves that urban design objectives and strategies are quite effective to reduce the heat island effects, which negatively affect the social environment and quality of life in urban areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Albedo" title="Albedo">Albedo</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20design" title=" urban design"> urban design</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20heat%20island" title=" urban heat island"> urban heat island</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20design" title=" sustainable design"> sustainable design</a> </p> <a href="https://publications.waset.org/abstracts/63178/reducing-the-urban-heat-island-effect-by-urban-design-strategies-case-study-of-aksaray-square-in-istanbul" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63178.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">580</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Extraction of Saponins and Cyclopeptides from Cow Cockle (Vaccaria hispanica (Mill.)

It is an important product due to its superior starch granules, triterpenic saponins, and cyclopeptides suitable for drug delivery. V. hispanica naturally grows in different climatic regions and has genotypes that differ in terms of seed content and composition. Sixty-six V. hispanica seed specimens were collected based on the representation of the distribution in all regions of Turkey and the determination of possible genotypic differences between regions. The seeds, collected from each of the 66 locations, were grown in greenhouse conditions in Akdeniz University, Antalya. Saponin and cyclopeptide contents of the V. hispanica seeds were determined after harvest. Accelerated solvent extraction (ASE) was applied for the extraction of saponins and cyclopeptides. Cyclopeptide (segetalin A) and saponin content of V. hispanica seeds were found in the range of 0.165-0.654 g/100 g and 0.15-1.14 g/100 g, respectively. The results were found to be promising for the seeds from Turkey in terms of saponin content and quality.

Currently, wastewater is a serious and increasing worldwide problem with an adverse effect on the environment and living organisms. For this reason, many technologies have been developed to treat wastewater before discharging it to water bodies. We have been discussed membrane technologies to remove contaminants from wastewater such as heavy metals, dyes, pesticides, etc., which represent the main pollutants in wastewater. All the properties of these technologies including performance, economics, simplicity, and operability are also compared with other wastewater treatment technologies. The conventional water treatment technologies have the disadvantages of low separation efficiency, high energy consumption, and strict operating temperature. To overcome these difficulties, membrane technologies have been developed and used in wastewater treatment. Membrane technology uses a selectively permeable membrane to remove suspended and dissolved solids from water. This membrane is a very thin film of synthetic organic or inorganic materials, that can allow a very selective separation between a mixture and its components. Examples of membrane technologies include microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO), electrodialysis (ED), gas separation, etc. Most of these technologies have been used extensively for the treatment of heavy metal wastewater. For instance, wastewater that contains Cu²⁺, Cd²⁺, Pb²⁺, Zn²⁺ was treated by ultraﬁltration technology. It was shown that complete removal of metal ions could be achieved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=industrial%20pollution" title="industrial pollution">industrial pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane%20technologies" title=" membrane technologies"> membrane technologies</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20ions" title=" metal ions"> metal ions</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater" title=" wastewater"> wastewater</a> </p> <a href="https://publications.waset.org/abstracts/97532/advances-in-membrane-technologies-for-wastewater-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97532.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">197</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> Protective Effect of hsa-miR-124 against to Bacillus anthracis Toxins on Human Macrophage Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Oztuna">Ali Oztuna</a>, <a href="https://publications.waset.org/abstracts/search?q=Meral%20%20Sarper"> Meral Sarper</a>, <a href="https://publications.waset.org/abstracts/search?q=Deniz%20Torun"> Deniz Torun</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Bayrakdar"> Fatma Bayrakdar</a>, <a href="https://publications.waset.org/abstracts/search?q=Selcuk%20Kilic"> Selcuk Kilic</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Baysallar"> Mehmet Baysallar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bacillus anthracis is one of the biological agents most likely to be used in case of bioterrorist attack as well as being the cause of anthrax. The bacterium's major virulence factors are the anthrax toxins and an antiphagocytic polyglutamic capsule. TEM8 (ANTXR1) and CMG2 (ANTXR2) are ubiquitously expressed type I transmembrane proteins, and ANTXR2 is the major receptor for anthrax toxins. MicroRNAs are 21-24 bp small noncoding RNAs that regulate gene expression by base pairing with the 3' UTR (untranslated regions) of their target mRNAs resulting in mRNA degradation and/or translational repression. MicroRNAs contribute to regulation of most biological processes and influence numerous pathological states like infectious disease. In this study, post-exposure (toxins) protective effect of the hsa-miR-124-3p against Bacillus anthracis was examined. In this context, i) THP-1 and U937 cells were differentiated to MΦ macrophage, ii) miRNA transfection efficiencies were evaluated by flow cytometry and qPCR, iii) protection against Bacillus anthracis toxins were investigated by XTT, cAMP ELISA and MEK2 cleavage assays.

The characterization was done by FT-IR. By adding Polyvinyl alcohol (PVA) to 4- VBBA-HAP, we obtained a suitable electrospinning solution. PVA solution which was also modified by using alkoxy silanes, in order to prevent the scaffolds from being damaged by aqueous cell medium, was added. Keratin was dissolved and then added into the electrospinning solution. Keratin containing 4-VBBA- HAP/PVA composite was used to fabricate nanofiber scaffolds with the simultaneous UV-reactive electrospinning technique. The structural characterization was done by FT-IR. Thermal gravimetric analysis was also performed by using TGA. The morphological characterization was determined by SEM analyses. Our second aim was to create a scaffold where cells could grow. With this purpose, suitable nanofibers were choosen according to their SEM analysis. Keratin containing nanofibers were seeded with 3T3, ECV and SAOS cells and their cytotoxicity and cell proliferation were investigated by using MTT assay. After cell culturing process morphological characterization was determined by SEM analyses. These scaffolds were designed to be nontoxic biomaterials. Here, a comparision was made between keratin containing 3T3, ECV and SAOS seeded nanofiber scaffolds and the results were presented and discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cell%20culture" title="cell culture">cell culture</a>, <a href="https://publications.waset.org/abstracts/search?q=keratin" title=" keratin"> keratin</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofibers" title=" nanofibers"> nanofibers</a>, <a href="https://publications.waset.org/abstracts/search?q=UV-reactive%20electrospinning" title=" UV-reactive electrospinning"> UV-reactive electrospinning</a> </p> <a href="https://publications.waset.org/abstracts/25095/uv-reactive-electrospinning-preparation-characterization-and-cell-culture-applications-of-nanofiber-scaffolds-containing-keratin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25095.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">454</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31</span> Ex (War) Machina: Arab Spring</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Deniz%20Alca">Deniz Alca</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research aims to study the themes of autonomy, democracy and the legitimacy of power under the headline of Arab Spring. After the first wave of Arab Spring, among the frequently mentioned ideals of self-recognition, awakening, democracy, autonomy, freedom etc. main concern of the border neighbors and the western governments was to see a “legitimate power.” Although the metaphor of spring was still pointing at emancipation, the principal focus was mostly not on the people but on the governments. So the question of what makes a government legitimate has come to the forefront. However, democracy and freedom, seems to be the main subject matters of the discussions, this rush about establishment of “legitimate governments” lead other countries, to indulge or worse endorse armed oppositionists. So essence of “power” changed from legitimate to rulership. It seems that the civil initiative or autonomy and clearly democracy are still far away from us. The need to a savior is overpowering. This cultural and traditional and almost hereditary miss orientation of the people, both the ones who are playing the role of god and the ones who believed the inevitable need to be freed by someone else, seems to be leading the Arabs to a new autocracy or worse. Middle East is waiting for the ex machina to operate. But what it gets is a spreading warfare. This darkness falling down on Middle East under the concept of spring may be explained by the confrontation of the concepts of emancipation and liberation. So the question is, if the era of emancipation really over or is there still a chance for autonomy and grassroots democracy operating as constituent power? <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autonomy" title="autonomy">autonomy</a>, <a href="https://publications.waset.org/abstracts/search?q=awakening" title=" awakening"> awakening</a>, <a href="https://publications.waset.org/abstracts/search?q=civil%20initiative" title=" civil initiative"> civil initiative</a>, <a href="https://publications.waset.org/abstracts/search?q=democracy" title=" democracy"> democracy</a>, <a href="https://publications.waset.org/abstracts/search?q=emancipation" title=" emancipation"> emancipation</a>, <a href="https://publications.waset.org/abstracts/search?q=legitimacy" title=" legitimacy"> legitimacy</a>, <a href="https://publications.waset.org/abstracts/search?q=liberation" title=" liberation"> liberation</a> </p> <a href="https://publications.waset.org/abstracts/30805/ex-war-machina-arab-spring" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30805.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">405</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Preoperative Parental Anxiety is not Associated with Postoperative Emergence Agitation in Children Undergoing Adenoidectomy and/or Tonsillectomy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20%C3%96cal">S.

Some studies found preoperative parental anxiety to be a predictor of EA. Methods: Seventy-four children, between the ages of 3-12 undergoing adenoidectomy/tonsillectomy at Ege University Hospital, were studied. Anesthesia was induced and maintained using 2% sevoflurane in 50% oxygen and 50% air following a premedicative dose of 0.5mg/kg oral midazolam. After the children were taken into the operating theater, the mothers were given the State-Trait Anxiety Inventory (STAI) questionnaire. To evaluate EA, Post Anesthetic Emergence Delirium (PAED) score of the children were noted every 10min during the first 30min of the postoperative period. EA was defined with a highest PAED score of ≥ 10, and non-EA with a highest PAED score of ≤ 9. Results: In this study, the incidence of postoperative EA was 31% (34% under the age of 6 and 19% over). Mothers of children with EA were found not to be significantly more anxious on STAI compared to mothers of non-EA children. Conclusions: Contrary to some earlier studies, we were unable to find an association between preoperative parental anxiety and postoperative EA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=parental%20anxiety" title="parental anxiety">parental anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=emergence%20agittion" title=" emergence agittion"> emergence agittion</a>, <a href="https://publications.waset.org/abstracts/search?q=Post%20Anesthetic%20Emergence%20Delirium" title=" Post Anesthetic Emergence Delirium"> Post Anesthetic Emergence Delirium</a>, <a href="https://publications.waset.org/abstracts/search?q=anesthesia" title=" anesthesia"> anesthesia</a> </p> <a href="https://publications.waset.org/abstracts/29527/preoperative-parental-anxiety-is-not-associated-with-postoperative-emergence-agitation-in-children-undergoing-adenoidectomy-andor-tonsillectomy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29527.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">29</span> Effects of Particle Size Distribution on Mechanical Strength and Physical Properties in Engineered Quartz Stone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Esra%20Arici">Esra Arici</a>, <a href="https://publications.waset.org/abstracts/search?q=Duygu%20Olmez"> Duygu Olmez</a>, <a href="https://publications.waset.org/abstracts/search?q=Murat%20Ozkan"> Murat Ozkan</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurcan%20Topcu"> Nurcan Topcu</a>, <a href="https://publications.waset.org/abstracts/search?q=Furkan%20Capraz"> Furkan Capraz</a>, <a href="https://publications.waset.org/abstracts/search?q=Gokhan%20Deniz"> Gokhan Deniz</a>, <a href="https://publications.waset.org/abstracts/search?q=Arman%20Altinyay"> Arman Altinyay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Engineered quartz stone is a composite material comprising approximately 90 wt.% fine quartz aggregate with a variety of particle size ranges and `10 wt.% unsaturated polyester resin (UPR). In this study, the objective is to investigate the influence of particle size distribution on mechanical strength and physical properties of the engineered stone slabs. For this purpose, granular quartz with two particle size ranges of 63-200 µm and 100-300 µm were used individually and mixed with a difference in ratios of mixing. The void volume of each granular packing was measured in order to define the amount of filler; quartz powder with the size of less than 38 µm, and UPR required filling inter-particle spaces. Test slabs were prepared using vibration-compression under vacuum. The study reports that both impact strength and flexural strength of samples increased as the mix ratio of the particle size range of 63-200 µm increased. On the other hand, the values of water absorption rate, apparent density and abrasion resistance were not affected by the particle size distribution owing to vacuum compaction. It is found that increasing the mix ratio of the particle size range of 63-200 µm caused the higher porosity. This led to increasing in the amount of the binder paste needed. It is also observed that homogeneity in the slabs was improved with the particle size range of 63-200 µm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=engineered%20quartz%20stone" title="engineered quartz stone">engineered quartz stone</a>, <a href="https://publications.waset.org/abstracts/search?q=fine%20quartz%20aggregate" title=" fine quartz aggregate"> fine quartz aggregate</a>, <a href="https://publications.waset.org/abstracts/search?q=granular%20packing" title=" granular packing"> granular packing</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20strength" title=" mechanical strength"> mechanical strength</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20size%20distribution" title=" particle size distribution"> particle size distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20properties." title=" physical properties."> physical properties.</a> </p> <a href="https://publications.waset.org/abstracts/110565/effects-of-particle-size-distribution-on-mechanical-strength-and-physical-properties-in-engineered-quartz-stone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110565.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Drivers of Deforestation in the Colombian Amazon: An Empirical Causal Loop Diagram of Food Security and Land-Use Change</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jesica%20L%C3%B3pez">Jesica López</a>, <a href="https://publications.waset.org/abstracts/search?q=Deniz%20Koca"> Deniz Koca</a>, <a href="https://publications.waset.org/abstracts/search?q=Asaf%20Tzachor"> Asaf Tzachor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In 2016 the historic peace accord between the Colombian government and the Revolutionary Armed Forces of Colombia (FARC) had no strong mechanism for managing changes to land use and the environment. Since the end of a 60-year conflict in Colombia, large areas of forest in the Amazon region have been rapidly converted to agricultural uses, most recently by cattle ranching. This suggests that the peace agreement presents a threat to the conservation of the country's rainforest. We analyze the effects of cattle ranching as a driver and accelerator of deforestation from a systemic perspective, focusing on two key leverage points the legal and illegal activities involved in the cattle ranching practices. We map and understand the inherent dynamic complexity of deforestation, including factors such as land policy instruments, national strategy to tackle deforestation, land use nexus with Amazonian food systems, and loss of biodiversity. Our results show that deforestation inside Colombian Protected Areas (PAs) in the Amazon region and the surrounding buffer areas has accelerated with the onset of peace. By using a systems analysis approach, we contextualized the competition of land between cattle ranching and the need to protect tropical forests and their biodiversity loss. We elaborate on future recommendations for land use management decisions making suggest the inclusion of an Amazonian food system, interconnecting and visualizing the synergies between sustainable development goals, climate action (SDG 13) and life on land (SDG 15). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tropical%20rainforest" title="tropical rainforest">tropical rainforest</a>, <a href="https://publications.waset.org/abstracts/search?q=deforestation" title=" deforestation"> deforestation</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20land%20use" title=" sustainable land use"> sustainable land use</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20security" title=" food security"> food security</a>, <a href="https://publications.waset.org/abstracts/search?q=Colombian%20Amazon" title=" Colombian Amazon"> Colombian Amazon</a> </p> <a href="https://publications.waset.org/abstracts/148832/drivers-of-deforestation-in-the-colombian-amazon-an-empirical-causal-loop-diagram-of-food-security-and-land-use-change" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148832.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">27</span> Purification of Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA) from Fish Oil Using HPLC Method and Investigation of Their Antibacterial Effects on Some Pathogenic Bacteria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y%C4%B1lmaz%20U%C3%A7ar">Yılmaz Uçar</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatih%20Ozogul"> Fatih Ozogul</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Durmu%C5%9F"> Mustafa Durmuş</a>, <a href="https://publications.waset.org/abstracts/search?q=Yesim%20Ozogul"> Yesim Ozogul</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20R%C4%B1za%20K%C3%B6%C5%9Fker"> Ali Rıza Köşker</a>, <a href="https://publications.waset.org/abstracts/search?q=Esmeray%20Kuley%20Bo%C4%9Fa"> Esmeray Kuley Boğa</a>, <a href="https://publications.waset.org/abstracts/search?q=Deniz%20Ayas"> Deniz Ayas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to purified eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), that are essential oils from trout oil, using high-performance liquid chromatography (HPLC) method, bioconverted EPA and DHA into bioconverted EPA (bEPA), bioconverted DHA (bDHA) extracts by P. aeruginosa PR3.

The bioconverted EPA and DHA exhibited antibacterial activities against two Gram-positive bacteria (Listeria monocytogenes ATCC 7677 and Staphylococcus aureus ATCC 29213) and six Gram-negative bacteria (Pseudomonas aeruginosa ATCC 27853, Escherichia coli ATCC 25922, Klebsiella pneumoniae ATCC700603, Enterococcus faecalis ATCC 29212, Aeromonas hydrophila NCIMB 1135, and Salmonella Paratyphi A NCTC 13). Inhibition zones and MIC value of bEPA and bDHA against bacterial strains ranged from 7 to 12 mm and from 350 to 2350 μg/mL, respectively. Our results suggested that the crude extracts of bioconversion of EPA and DHA by P. aeruginosa PR3 can be considered as promising antimicrobials in improving food safety by controlling foodborne pathogens. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=High-Performance%20Liquid%20Chromatography%20%28HPLC%29" title="High-Performance Liquid Chromatography (HPLC)">High-Performance Liquid Chromatography (HPLC)</a>, <a href="https://publications.waset.org/abstracts/search?q=docosahexaenoic%20acid" title=" docosahexaenoic acid"> docosahexaenoic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=DHA" title=" DHA"> DHA</a>, <a href="https://publications.waset.org/abstracts/search?q=eicosapentaenoic%20acid" title=" eicosapentaenoic acid"> eicosapentaenoic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=EPA" title=" EPA"> EPA</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20inhibitory%20concentration" title=" minimum inhibitory concentration"> minimum inhibitory concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=MIC" title=" MIC"> MIC</a>, <a href="https://publications.waset.org/abstracts/search?q=Pseudomonas%20aeruginosa%20PR3" title=" Pseudomonas aeruginosa PR3"> Pseudomonas aeruginosa PR3</a> </p> <a href="https://publications.waset.org/abstracts/21883/purification-of-eicosapentaenoic-acid-epa-and-docosahexaenoic-acid-dha-from-fish-oil-using-hplc-method-and-investigation-of-their-antibacterial-effects-on-some-pathogenic-bacteria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21883.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">499</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Stigma and Discrimination toward Mental Illness: Translation and Validation of the Attribution Questionnaire-27 (AQ-27)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gokcen%20Akyurek">Gokcen Akyurek</a>, <a href="https://publications.waset.org/abstracts/search?q=Hulya%20Kayihan"> Hulya Kayihan</a>, <a href="https://publications.waset.org/abstracts/search?q=Deniz%20Yuce"> Deniz Yuce</a>, <a href="https://publications.waset.org/abstracts/search?q=Selen%20Yilmaz"> Selen Yilmaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The stigma towards mental illness is still very rooted in our society, despite the number of studies, campaigns, and anti-stigma programs developed in recent years. Stigma represents a serious obstacle to recovery and social integration for people who experience a mental illness, affecting directly their well-being and quality of life. It implies that these persons have to deal with many other barriers apart from the disease symptoms (1-5). Convergent, recent literature suggests that less positive attitudes by mental health professionals interfere with the self-determination and recovery process (4-10).The aim of this study was to translate the Attribution Questionnaire-27 (AQ-27) to the Turkish language (AQ-27-T), and to examine the reliability and validity of this new Turkish version. Cultural adaptation was implemented according to the internationally suggested method. To determine the understandability and appropriateness of this measure for the Turkish culture, a pretest was administered and the final form was generated. Then, 424 randomly chosen people took part in the study. Participant’s mean age was 36.9±12.7 years and %52 of them female. Cronbach's alpha and intra-class coefficients were used to estimate instrument reliability. The AQ-27-T was assessed again 14 days later for test retest reliability. The AQ-27-T demonstrated acceptable internal consistency, with a Cronbach's alpha of 0.88 for the total scale and ranging between 0.86 and 0.89 for the items. The test-retest reliability was good, with Pearson correlation coefficients of 0.79 for the total scale and ranging between 0.35 and 0.77 for the items (p<0.05). Correlation between subscales was moderate-good, with Pearson correlation coefficients of 0.18-0.88 (p<0.05). Fit indices of the model supported the factor structure and paths. The AQ-27-T is a reliable measure to assess stigmatizing attitudes in Turkish. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attribution%20questionnaire" title="attribution questionnaire">attribution questionnaire</a>, <a href="https://publications.waset.org/abstracts/search?q=validity" title=" validity"> validity</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability" title=" reliability"> reliability</a>, <a href="https://publications.waset.org/abstracts/search?q=stigma" title=" stigma"> stigma</a> </p> <a href="https://publications.waset.org/abstracts/40371/stigma-and-discrimination-toward-mental-illness-translation-and-validation-of-the-attribution-questionnaire-27-aq-27" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40371.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">442</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> The Types of Annuities with Flexible Premium </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Deniz%20%C3%9Cnal%20%C3%96zpalamutcu">Deniz Ünal Özpalamutcu</a>, <a href="https://publications.waset.org/abstracts/search?q=Burcu%20Altman"> Burcu Altman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Actuaria uses mathematics, statistic and financial information when analyzing the financial impacts of uncertainties, risks, insurance and pension related issues. In other words, it deals with the likelihood of potential risks, their financial impacts and especially the financial measures. Handling these measures require some long-term payment and investments. So, it is obvious it is inevitable to plan the periodic payments with equal time intervals considering also the changing value of money over time. These series of payment made specific intervals of time is called annuity or rant. In literature, rants are classified based on start and end dates, start times, payments times, payments amount or frequency. Classification of rants based on payment amounts changes based on the constant, descending or ascending payment methods. The literature about handling the annuity is very limited. Yet in a daily life, especially in today’s world where the economic issues gained a prominence, it is very crucial to use the variable annuity method in line with the demands of the customers. In this study, the types of annuities with flexible payment are discussed. In other words, we focus on calculating payment amount of a period by adding a certain percentage of previous period payment was studied. While studying this problem, formulas were created considering both start and end period payments for cash value and accumulated. Also increase of each period payment by r interest rate each period payments calculated with previous periods increases. And the problem of annuities (rants) of which each period payment increased with previous periods’ increase by r interest rate has been analyzed. Cash value and accumulated value calculation of this problem were studied separately based on the period start/end and their relations were expressed by formulas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=actuaria" title="actuaria">actuaria</a>, <a href="https://publications.waset.org/abstracts/search?q=annuity" title=" annuity"> annuity</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20payment" title=" flexible payment"> flexible payment</a>, <a href="https://publications.waset.org/abstracts/search?q=rant" title=" rant"> rant</a> </p> <a href="https://publications.waset.org/abstracts/37295/the-types-of-annuities-with-flexible-premium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37295.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">221</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Treatment of Acid Mine Lake by Ultrasonically Modified Fly Ash at Different Frequencies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Burcu%20Ileri">Burcu Ileri</a>, <a href="https://publications.waset.org/abstracts/search?q=Deniz%20%20Sanliyuksel%20Yucel"> Deniz Sanliyuksel Yucel</a>, <a href="https://publications.waset.org/abstracts/search?q=Onder%20Ayyildiz"> Onder Ayyildiz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The oxidation of pyrite in water results in the formation of acid mine drainage, which typically forms extremely acid mine lake (AML) in the depression areas of abandoned Etili open-pit coal mine site, Northwest Turkey. Nine acid mine lakes of various sizes have been located in the Etili coal mine site. Hayirtepe AML is one of the oldest lake having a mean pH value of 2.9 and conductivity of 4550 μS/cm, and containing elevated concentrations of Al, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, and Zn. The water quality of the lake has been deteriorated due to its high chemical composition, in particular, increasing heavy metal pollution. In this study, fly ash (FA), a coal combustion by-product from fluidized bed thermal power plant in the northwestern part of Turkey, was used as an adsorbent for the treatment of Hayirtepe AML. The FA is a relatively abundant and cost effective material, but its use in adsorption processes usually require excessive adsorbent doses. To increase adsorption efficiency and lower the adsorbent dose, we modified the FA by means of ultrasonic treatment (20 kHz and 40 kHz). The images of scanning electron microscopy (SEM) have demonstrated that ultrasonic treatment not only decreased the size of ash particles but also created pits and cracks on their surfaces which in turn led to a significant increase in the BET surface area. Both FA and modified fly ash were later tested for the removal of heavy metals from the AML. The effect of various operating parameters such as ultrasonic power, pH, ash dose, and adsorption contact time were examined to obtain the optimum conditions for the treatment process. The results have demonstrated that removal of heavy metals by ultrasound-modified fly ash requires much shorter treatment times and lower adsorbent doses than those attained by the unmodified fly ash. This research was financially supported by the Scientific and Technological Research Council of Turkey (TUBITAK), (Project no: 116Y510). <p class="card-text"><strong>Keywords:</strong> <a
