In this study, the effects of different fillers, such as silica aerogel and polystyrene, on the tensile strength, thermal insulation, and sound insulation of epoxy composites have been analyzed. Results from the experimental studies show that both tensile strength and insulation properties (sound and thermal insulation) of the epoxy composite increased by the use of silica aerogel additive. Polystyrene additive significantly increases the sound absorption coefficient of the epoxy composite.

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.

Studies on piezoelectric ceramic transducers (PZT) for diagnostics and health monitoring have gained attention for their sensing capabilities, however PZT structures are prone to fail in case of heavy operational loads. In this paper, we develop a piezo-based Glass Fiber Reinforced Polymer (GFRP) composite finite element (FE) model, validate with experimental setup, and identify the applicability and limitations of PZTs for a marine application. A case study is conducted to assess the piezo-based sensing capabilities in a representative marine composite structure. A FE model of the composite structure combined with PZT patches is developed, afterwards the response and functionality are investigated according to the sea conditions. Results of this study clearly indicate the blockers and critical aspects towards industrialization and wide-range use of PZTs for marine composite applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FRP%20composite" title="FRP composite">FRP composite</a>, <a href="https://publications.waset.org/abstracts/search?q=operational%20challenges" title=" operational challenges"> operational challenges</a>, <a href="https://publications.waset.org/abstracts/search?q=piezoelectric%20transducers" title=" piezoelectric transducers"> piezoelectric transducers</a>, <a href="https://publications.waset.org/abstracts/search?q=FE%20modeling" title=" FE modeling"> FE modeling</a> </p> <a href="https://publications.waset.org/abstracts/134034/operational-challenges-of-marine-fiber-reinforced-polymer-composite-structures-coupled-with-piezoelectric-transducers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134034.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">174</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</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.

Polyacrylonitrile/N,N-dimethylformamide (PAN/DMF) solution has been prepared and the amount of silver nitrate has been adjusted to PAN weight. 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. It has been seen that breaking strength, conductivity, antimicrobial effect, enthalpy during cyclization increase by use of silver nano-particles while the diameter of nano-fiber decreases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20polyacrylonitrile%20nanofiber" title="composite polyacrylonitrile nanofiber">composite polyacrylonitrile nanofiber</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20conductivity" title=" electrical conductivity"> electrical conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title=" electrospinning"> electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20properties" title=" thermal properties"> thermal properties</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20nanoparticles" title=" silver nanoparticles"> silver nanoparticles</a> </p> <a href="https://publications.waset.org/abstracts/7504/investigation-of-electrical-thermal-and-structural-properties-on-polyacrylonitrile-nano-fiber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7504.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">418</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> Ammonia and Biogenic Amine Production of Fish Spoilage Bacteria: Affected by Olive Leaf, Olive Cake and Black Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Kuley">E.

Fish spoilage bacteria produced all biogenic amine tested, mainly histamine and serotonin. Ammonia was accumulated more than 13.60 mg/L. Histamine production was in range 37.50 mg/L by Ser. liquefaciens and 86.71 mg/L by Ent. cloacae. The highest putrescine and cadaverine production was observed by Ent. cloacae (17.80 vs. 17.69 mg/L). The presence of OL, OC and BW in the broth significantly affected biogenic amine accumulation by bacteria. The antibacterial effect of olive by products depended on bacterial strains. OL and OC resulted in significant inhibition effect on HIS accumulation by bacteria apart from Ser. liquefaciens and Prot. mirabilis. The study result revealed that usefulness of OL and OC to prevent the accumulation of this amine which may affect human health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antimicrobials" title="Antimicrobials">Antimicrobials</a>, <a href="https://publications.waset.org/abstracts/search?q=biogenic%20amine" title=" biogenic amine"> biogenic amine</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20spoilage%20bacteria" title=" fish spoilage bacteria"> fish spoilage bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=olive-by%20products" title=" olive-by products"> olive-by products</a> </p> <a href="https://publications.waset.org/abstracts/19395/ammonia-and-biogenic-amine-production-of-fish-spoilage-bacteria-affected-by-olive-leaf-olive-cake-and-black-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19395.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">503</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> The Effects of Nanoemulsions Based on Commercial Oils: Sunflower, Canola, Corn, Olive, Soybean, and Hazelnut Oils for the Quality of Farmed Sea Bass at 2±2°C</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yesim%20Ozogul">Yesim 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=Fatih%20Ozogul"> Fatih Ozogul</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=Y%C4%B1lmaz%20U%C3%A7ar"> Yılmaz Uçar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hatice%20Yazgan"> Hatice Yazgan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effects of oil-in-water nanoemulsions on the sensory, chemical (total volatile basic nitrogen (TVB-N), thiobarbituric acid (TBA), peroxide value (PV) and free fatty acids (FFA), and microbiological qualities (total viable count (TVC), total psychrophilic bacteria, and total Enterbactericaea bacteria) of sea bream fillets stored at 2 ± 2°C were investigated. Physical properties of emulsions (viscosity, the particle size of droplet, thermodynamic stability, refractive index and surface tension) were determined. The results showed that the use of nanoemulsion extended the shelf life of fish 2 days when compared with the control.

Carbon nanotubes (CNTs) have unique structural, mechanical, and electrical properties and can be used together with graphene oxide fibers for several application areas such as lithium ion batteries, wearable electronics, etc. Metals salts that can be converted into metal ions and metal oxide can be also used for several application areas such as battery, purification natural gas, filtration, absorption. This study investigates the effects of CNT and metal complex compounds (MnCl₂, metal salts) on the morphological structure of graphene oxide fibers. The graphene oxide dispersion was manufactured by modified Hummers method, and continuous graphene oxide fibers were produced with wet spinning. The CNT and MnCl₂ were incorporated into the coagulation baths during wet spinning process.

Thus, this study was conducted to evaluate the efficiency of different extraction methods (Bligh and Dyer, soxhlet, microwave and ultrasonics) on the fat content and fatty acid profiles of marine fish species (Mullus babatus, Upeneus moluccensis, Mullus surmuletus, Anguilla anguilla, Pagellus erythrinus and Saurida undosquamis). Fish species were caught by trawl in Mediterranean Sea and immediately iced. After that, fish were transported to laboratory in ice and stored at -18oC in a freezer until the day of analyses. After extracting lipid from fish by different methods, lipid samples were converted to their constituent fatty acid methyl esters. The fatty acid composition was analysed by a GC Clarus 500 with an autosampler (Perkin Elmer, Shelton, CT, USA) equipped with a flame ionization detector and a fused silica capillary SGE column (30 m x 0.32 mm ID x 0.25 mm BP20 0.25 UM, USA).

Material and Method: This research was conducted on the basis of the real test model with the pre-test /post-test control groups. The study population consists of pregnant women registered in the six different Family Health Centers located in the central Malatya districts of Yeşilyurt and Battalgazi. When power analysis is done, the sample size was calculated for each group of at least 55 pregnant women (55 tests, 55 controls). The data were collected by using Personal Information Form and MAAS (Maternal Antenatal Attachment Scale) between July 2015-June 2016. Fetal movement counting training was given to pregnant women by researchers in the experimental group after the pre-test data collection. No intervention was applied to the control group. Post-test data for both groups were collected after four weeks. Data were evaluated with percentage, chi-square arithmetic average, chi-square test and as for the dependent and independent group’s t test. Result: In the MAAS, the pre-test average of total scores in the experimental group is 70.78±6.78, control group is also 71.58±7.54 and so there was no significant difference in mean scores between the two groups (p>0.05). MAAS post-test average of total scores in the experimental group is 78.41±6.65, control group is also is 72.25±7.16 and so the mean scores between groups were found to have statistically significant difference (p<0.05). Conclusion: It was determined that fetal movement counting increases the maternal antenatal attachments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antenatal%20maternal%20attachment" title="antenatal maternal attachment">antenatal maternal attachment</a>, <a href="https://publications.waset.org/abstracts/search?q=fetal%20movement%20counting" title=" fetal movement counting"> fetal movement counting</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnancy" title=" pregnancy"> pregnancy</a>, <a href="https://publications.waset.org/abstracts/search?q=midwifery" title=" midwifery"> midwifery</a> </p> <a href="https://publications.waset.org/abstracts/57377/the-effect-of-fetal-movement-counting-on-maternal-antenatal-attachment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57377.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">271</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> 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. Moreover, in vitro antibacterial activity of bEPA and bDHA was investigated using disc diffusion methods and minimum inhibitory concentration (MIC). EPA and DHA concentration of 11.1% and 15.9% in trout oil increased in 58.64% and 40.33% after HPLC optimisation, respectively. In this study, EPA and DHA enriched products were obtained which are to be used as valuable supplements for food and pharmaceutical purposes. 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">498</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> Monitoring of Cannabis Cultivation with High-Resolution Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Levent%20Basayigit">Levent Basayigit</a>, <a href="https://publications.waset.org/abstracts/search?q=Sinan%20Demir"> Sinan Demir</a>, <a href="https://publications.waset.org/abstracts/search?q=Burhan%20Kara"> Burhan Kara</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Ucar">Yusuf Ucar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cannabis is mostly used for drug production. In some countries, an excessive amount of illegal cannabis is cultivated and sold. Most of the illegal cannabis cultivation occurs on the lands far from settlements. In farmlands, it is cultivated with other crops. In this method, cannabis is surrounded by tall plants like corn and sunflower. It is also cultivated with tall crops as the mixed culture. The common method of the determination of the illegal cultivation areas is to investigate the information obtained from people. This method is not sufficient for the determination of illegal cultivation in remote areas. For this reason, more effective methods are needed for the determination of illegal cultivation. Remote Sensing is one of the most important technologies to monitor the plant growth on the land. The aim of this study is to monitor cannabis cultivation area using satellite imagery. The main purpose of this study was to develop an applicable method for monitoring the cannabis cultivation. For this purpose, cannabis was grown as single or surrounded by the corn and sunflower in plots. The morphological characteristics of cannabis were recorded two times per month during the vegetation period. The spectral signature library was created with the spectroradiometer. The parcels were monitored with high-resolution satellite imagery. With the processing of satellite imagery, the cultivation areas of cannabis were classified. To separate the Cannabis plots from the other plants, the multiresolution segmentation algorithm was found to be the most successful for classification. WorldView Improved Vegetative Index (WV-VI) classification was the most accurate method for monitoring the plant density. As a result, an object-based classification method and vegetation indices were sufficient for monitoring the cannabis cultivation in multi-temporal Earthwiev images. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cannabis" title="Cannabis">Cannabis</a>, <a href="https://publications.waset.org/abstracts/search?q=drug" title=" drug"> drug</a>, <a href="https://publications.waset.org/abstracts/search?q=remote%20sensing" title=" remote sensing"> remote sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=object-based%20classification" title=" object-based classification"> object-based classification</a> </p> <a href="https://publications.waset.org/abstracts/74202/monitoring-of-cannabis-cultivation-with-high-resolution-images" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74202.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">4</span> Assessment of Wastewater Reuse Potential for an Enamel Coating Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guclu%20Insel">Guclu Insel</a>, <a href="https://publications.waset.org/abstracts/search?q=Efe%20Gumuslu"> Efe Gumuslu</a>, <a href="https://publications.waset.org/abstracts/search?q=Gulten%20Yuksek"> Gulten Yuksek</a>, <a href="https://publications.waset.org/abstracts/search?q=Nilay%20Sayi%20Ucar"> Nilay Sayi Ucar</a>, <a href="https://publications.waset.org/abstracts/search?q=Emine%20Ubay%20Cokgor"> Emine Ubay Cokgor</a>, <a href="https://publications.waset.org/abstracts/search?q=Tugba%20Olmez%20Hanci"> Tugba Olmez Hanci</a>, <a href="https://publications.waset.org/abstracts/search?q=Didem%20Okutman%20Tas"> Didem Okutman Tas</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatos%20Germirli%20Babuna"> Fatos Germirli Babuna</a>, <a href="https://publications.waset.org/abstracts/search?q=Derya%20Firat%20Ertem"> Derya Firat Ertem</a>, <a href="https://publications.waset.org/abstracts/search?q=Okmen%20Yildirim"> Okmen Yildirim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ozge%20Erturan"> Ozge Erturan</a>, <a href="https://publications.waset.org/abstracts/search?q=Betul%20Kirci"> Betul Kirci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to eliminate water scarcity problems, effective precautions must be taken. Growing competition for water is increasingly forcing facilities to tackle their own water scarcity problems. At this point, application of wastewater reclamation and reuse results in considerable economic advantageous. In this study, an enamel coating facility, which is one of the high water consumed facilities, is evaluated in terms of its wastewater reuse potential. Wastewater reclamation and reuse can be defined as one of the best available techniques for this sector. Hence, process and pollution profiles together with detailed characterization of segregated wastewater sources are appraised in a way to find out the recoverable effluent streams arising from enamel coating operations. Daily, 170 m<sup>3</sup> of process water is required and 160 m<sup>3</sup> of wastewater is generated. The segregated streams generated by two enamel coating processes are characterized in terms of conventional parameters. Relatively clean segregated wastewater streams (reusable wastewaters) are separately collected and experimental treatability studies are conducted on it. The results reflected that the reusable wastewater fraction has an approximate amount of 110 m<sup>3</sup>/day that accounts for 68% of the total wastewaters. The need for treatment applicable on reusable wastewaters is determined by considering water quality requirements of various operations and characterization of reusable wastewater streams. Ultra-filtration (UF), Nano-filtration (NF) and Reverse Osmosis (RO) membranes are subsequently applied on reusable effluent fraction. Adequate organic matter removal is not obtained with the mentioned treatment sequence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=enamel%20coating" title="enamel coating">enamel coating</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane" title=" membrane"> membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=reuse" title=" reuse"> reuse</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater%20reclamation" title=" wastewater reclamation"> wastewater reclamation</a> </p> <a href="https://publications.waset.org/abstracts/44839/assessment-of-wastewater-reuse-potential-for-an-enamel-coating-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44839.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">328</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> Spectral Mixture Model Applied to Cannabis Parcel Determination </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Levent%20Basayigit">Levent Basayigit</a>, <a href="https://publications.waset.org/abstracts/search?q=Sinan%20Demir"> Sinan Demir</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Ucar"> Yusuf Ucar</a>, <a href="https://publications.waset.org/abstracts/search?q=Burhan%20Kara"> Burhan Kara</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many research projects require accurate delineation of the different land cover type of the agricultural area. Especially it is critically important for the definition of specific plants like cannabis. However, the complexity of vegetation stands structure, abundant vegetation species, and the smooth transition between different seconder section stages make vegetation classification difficult when using traditional approaches such as the maximum likelihood classifier. Most of the time, classification distinguishes only between trees/annual or grain. It has been difficult to accurately determine the cannabis mixed with other plants. In this paper, a mixed distribution models approach is applied to classify pure and mix cannabis parcels using Worldview-2 imagery in the Lakes region of Turkey. Five different land use types (i.e. sunflower, maize, bare soil, and cannabis) were identified in the image. A constrained Gaussian mixture discriminant analysis (GMDA) was used to unmix the image. In the study, 255 reflectance ratios derived from spectral signatures of seven bands (Blue-Green-Yellow-Red-Rededge-NIR1-NIR2) were randomly arranged as 80% for training and 20% for test data. Gaussian mixed distribution model approach is proved to be an effective and convenient way to combine very high spatial resolution imagery for distinguishing cannabis vegetation. Based on the overall accuracies of the classification, the Gaussian mixed distribution model was found to be very successful to achieve image classification tasks. This approach is sensitive to capture the illegal cannabis planting areas in the large plain. This approach can also be used for monitoring and determination with spectral reflections in illegal cannabis planting areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gaussian%20mixture%20discriminant%20analysis" title="Gaussian mixture discriminant analysis">Gaussian mixture discriminant analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=spectral%20mixture%20model" title=" spectral mixture model"> spectral mixture model</a>, <a href="https://publications.waset.org/abstracts/search?q=Worldview-2" title=" Worldview-2"> Worldview-2</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20parcels" title=" land parcels"> land parcels</a> </p> <a href="https://publications.waset.org/abstracts/89000/spectral-mixture-model-applied-to-cannabis-parcel-determination" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89000.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">2</span> Effects of the Coagulation Bath and Reduction Process on SO2 Adsorption Capacity of Graphene Oxide Fiber</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C3%96zge%20Alpto%C4%9Fa">Özge Alptoğa</a>, <a href="https://publications.waset.org/abstracts/search?q=Nuray%20U%C3%A7ar"> Nuray Uçar</a>, <a href="https://publications.waset.org/abstracts/search?q=Nilg%C3%BCn%20Karatepe%20Yavuz"> Nilgün Karatepe Yavuz</a>, <a href="https://publications.waset.org/abstracts/search?q=Ay%C5%9Fen%20%C3%96nen"> Ayşen Önen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sulfur dioxide (SO<sub>2</sub>) is a very toxic air pollutant gas and it causes the greenhouse effect, photochemical smog, and acid rain, which threaten human health severely. 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> Assessment of Water Reuse Potential in a Metal Finishing Factory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Efe%20Gumuslu">Efe Gumuslu</a>, <a href="https://publications.waset.org/abstracts/search?q=Guclu%20Insel"> Guclu Insel</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%BClten%20Yuksek"> Gülten Yuksek</a>, <a href="https://publications.waset.org/abstracts/search?q=Nilay%20Sayi%20Ucar"> Nilay Sayi Ucar</a>, <a href="https://publications.waset.org/abstracts/search?q=Emine%20Ubay%20Cokgor"> Emine Ubay Cokgor</a>, <a href="https://publications.waset.org/abstracts/search?q=Tu%C4%9Fba%20Olmez%20Hanci"> Tuğba Olmez Hanci</a>, <a href="https://publications.waset.org/abstracts/search?q=Didem%20Okutman%20Tas"> Didem Okutman Tas</a>, <a href="https://publications.waset.org/abstracts/search?q=Fato%C5%9F%20Germirli%20Babuna"> Fatoş Germirli Babuna</a>, <a href="https://publications.waset.org/abstracts/search?q=Derya%20Firat%20Ertem"> Derya Firat Ertem</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96kmen%20Yildirim"> Ökmen Yildirim</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96zge%20Erturan"> Özge Erturan</a>, <a href="https://publications.waset.org/abstracts/search?q=Bet%C3%BCl%20Kirci"> Betül Kirci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although water reclamation and reuse are inseparable parts of sustainable production concept all around the world, current levels of reuse constitute only a small fraction of the total volume of industrial effluents. Nowadays, within the perspective of serious climate change, wastewater reclamation and reuse practices should be considered as a requirement. Industrial sector is one of the largest users of water sources. The OECD Environmental Outlook to 2050 predicts that global water demand for manufacturing will increase by 400% from 2000 to 2050 which is much larger than any other sector. Metal finishing industry is one of the industries that requires high amount of water during the manufacturing. Therefore, actions regarding the improvement of wastewater treatment and reuse should be undertaken on both economic and environmental sustainability grounds. Process wastewater can be reused for more purposes if the appropriate treatment systems are installed to treat the wastewater to the required quality level. Recent studies showed that membrane separation techniques may help in solving the problem of attaining a suitable quality of water that allows being recycled back to the process. The metal finishing factory where this study is conducted is one of the biggest white-goods manufacturers in Turkey. The sheet metal parts used in the cookers production have to be exposed to surface pre-treatment processes composed of degreasing, rinsing, nanoceramics coating and deionization rinsing processes, consecutively. The wastewater generating processes in the factory are enamel coating, painting and styrofoam processes. In the factory, the main source of water is the well water. While some part of the well water is directly used in the processes after passing through resin treatment, some portion of it is directed to the reverse osmosis treatment to obtain required water quality for enamel coating and painting processes. In addition to these processes another important source of water that can be considered as a potential water source is rainwater (3660 tons/year). In this study, process profiles as well as pollution profiles were assessed by a detailed quantitative and qualitative characterization of the wastewater sources generated in the factory. Based on the preliminary results the main water sources that can be considered for reuse in the processes were determined as painting and styrofoam processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=enamel%20coating" title="enamel coating">enamel coating</a>, <a href="https://publications.waset.org/abstracts/search?q=painting" title=" painting"> painting</a>, <a href="https://publications.waset.org/abstracts/search?q=reuse" title=" reuse"> reuse</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater" title=" wastewater"> wastewater</a> </p> <a href="https://publications.waset.org/abstracts/44838/assessment-of-water-reuse-potential-in-a-metal-finishing-factory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44838.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">379</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); });*/ jQuery.get({ url: "https://publications.waset.org/xhr/user-menu", cache: false }).then(function(response){ jQuery('#mainNavMenu').append(response); }); }); </script> </body> </html>
