All the household and industrial waste arising from Dakar are stored in this open landfill without being covered and are therefore possible sources of Pb and Cd contaminated air emissions and lixiviates. The objective of this study is part of improving the health of the population neighboring Mbeubeuss by determining Pb and Cd concentrations both in environment and humans, and studying possible renal function alterations within the adults. Soil and air samples were collected in the control site (Darou Salam) and the waste dump neighboring site (Diamalaye II). Control and exposed adults were recruited as living in Darou Salam (n = 52) and in Diamalaye II (n = 77). Pb and Cd concentrations in soil, air and biological samples were determined. Moreover, we were interested in analyzing some impregnation (zinc protoporphyrin, d-aminolevulinic acid dehydratase) and oxidative stress biomarkers (malonedialdehyde, gluthatione status), in addition to several nephrotoxicity parameters (creatinuria, proteinuria, lactate dehydrogenase, CC16 protein, glutathione S-transferase-alpha and retinol binding protein) in blood and/or urine. The results showed the significant Pb and Cd contamination of the soil and air samples derived from the landfill, and therefore of the neighboring population of adults. This critical exposure to environmental Pb and Cd had some harmful consequences for their health, as shown by the reported oxidative stress and nephrotoxicity signs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pb%20and%20Cd%20environmental%20exposure" title="Pb and Cd environmental exposure">Pb and Cd environmental exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=impregnation%20markers" title=" impregnation markers"> impregnation markers</a>, <a href="https://publications.waset.org/abstracts/search?q=landfill" title=" landfill"> landfill</a>, <a href="https://publications.waset.org/abstracts/search?q=nephrotoxicity%20markers" title=" nephrotoxicity markers"> nephrotoxicity markers</a> </p> <a href="https://publications.waset.org/abstracts/18333/impact-of-cd-and-pb-impregnation-on-the-health-of-an-adult-population-neighbouring-a-landfill" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18333.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">880</span> Propane Dehydrogenation with Better Stability by a Modified Pt-Based Catalyst</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Napat%20Hataivichian">Napat Hataivichian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effect of transition metal doping on Pt/Al2O3 catalyst used in propane dehydrogenation reaction at 500˚C was studied. The preparation methods investigated were sequential impregnation (Pt followed by the 2nd metal or the 2nd metal followed by Pt) and co-impregnation. The metal contents of these catalysts were fixed as the weight ratio of Pt per the 2nd metal of around 0.075. These catalysts were characterized by N2-physisorption, TPR, CO-chemisorption and NH3-TPD. It was found that the impregnated 2nd metal had an effect upon reducibility of Pt due to its interaction with transition metal-containing structure. This was in agreement with the CO-chemisorption result that the presence of Pt metal, which is a result from Pt species reduction, was decreased. The total acidity of bimetallic catalysts is decreased but the strong acidity is slightly increased. It was found that the stability of bimetallic catalysts prepared by co-impregnation and sequential impregnation where the 2nd metal was impregnated before Pt were better than that of monometallic catalyst (undoped Pt one) due to the forming of Pt sites located on the transition metal-oxide modified surface. Among all preparation methods, the sequential impregnation method- having Pt impregnated before the 2nd metal gave the worst stability because this catalyst lacked the modified Pt sites and some fraction of Pt sites was covered by the 2nd metal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alumina" title="alumina">alumina</a>, <a href="https://publications.waset.org/abstracts/search?q=dehydrogenation" title=" dehydrogenation"> dehydrogenation</a>, <a href="https://publications.waset.org/abstracts/search?q=platinum" title=" platinum"> platinum</a>, <a href="https://publications.waset.org/abstracts/search?q=transition%20metal" title=" transition metal"> transition metal</a> </p> <a href="https://publications.waset.org/abstracts/25499/propane-dehydrogenation-with-better-stability-by-a-modified-pt-based-catalyst" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25499.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">310</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">879</span> Fire Smoke Removal over Cu-Mn-Ce Oxide Catalyst with CO₂ Sorbent Addition: Co Oxidation and in-situ CO₂ Sorption</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jin%20Lin">Jin Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Shouxiang%20Lu"> Shouxiang Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Kim%20Meow%20Liew"> Kim Meow Liew</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In a fire accident, fire smoke often poses a serious threat to human safety especially in the enclosed space such as submarine and space-crafts environment. Efficient removal of the hazardous gas products particularly a large amount of CO and CO₂ gases from these confined space is critical for the security of the staff and necessary for the post-fire environment recovery. In this work, Cu-Mn-Ce composite oxide catalysts coupled with CO₂ sorbents were prepared using wet impregnation method, solid-state impregnation method and wet/solid-state impregnation method. The as-prepared samples were tested dynamically and isothermally for CO oxidation and CO₂ sorption and further characterized by the X-ray diffraction (XRD), nitrogen adsorption and desorption, and field emission scanning electron microscopy (FE-SEM). The results showed that all the samples were able to catalyze CO into CO₂ and capture CO₂ in situ by chemisorption. Among all the samples, the sample synthesized by the wet/solid-state impregnation method showed the highest catalytic activity toward CO oxidation and the fine ability of CO₂ sorption. The sample prepared by the solid-state impregnation method showed the second CO oxidation performance, while the coupled sample using the wet impregnation method exhibited much poor CO oxidation activity. The various CO oxidation and CO₂ sorption properties of the samples might arise from the different dispersed states of the CO₂ sorbent in the CO catalyst, owing to the different preparation methods. XRD results confirmed the high-dispersed sorbent phase in the samples prepared by the wet and solid impregnation method, while that of the sample prepared by wet/solid-state impregnation method showed the larger bulk phase as indicated by the high-intensity diffraction peaks. Nitrogen adsorption and desorption results further revealed that the latter sample had a higher surface area and pore volume, which were beneficial for the CO oxidation over the catalyst. Hence, the Cu-Mn-Ce oxide catalyst coupled with CO₂ sorbent using wet/solid-state impregnation method could be a good choice for fire smoke removal in the enclosed space. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CO%20oxidation" title="CO oxidation">CO oxidation</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20sorption" title=" CO₂ sorption"> CO₂ sorption</a>, <a href="https://publications.waset.org/abstracts/search?q=preparation%20methods" title=" preparation methods"> preparation methods</a>, <a href="https://publications.waset.org/abstracts/search?q=smoke%20removal" title=" smoke removal"> smoke removal</a> </p> <a href="https://publications.waset.org/abstracts/108653/fire-smoke-removal-over-cu-mn-ce-oxide-catalyst-with-co2-sorbent-addition-co-oxidation-and-in-situ-co2-sorption" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108653.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">139</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">878</span> Application of Molecular Markers for Crop Improvement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monisha%20Isaac">Monisha Isaac</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Use of molecular markers for selecting plants with desired traits has been started long back. Due to their heritable characteristics, they are useful for identification and characterization of specific genotypes. The study involves various types of molecular markers used to select multiple desired characters in plants, their properties, and advantages to improve crop productivity in adverse climatological conditions for the purpose of providing food security to fast-growing global population. The study shows that genetic similarities obtained from molecular markers provide more accurate information and the genetic diversity can be better estimated from the genetic relationship obtained from the dendrogram. The information obtained from markers assisted characterization is more suitable for the crops of economic importance like sugarcane. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=molecular%20markers" title="molecular markers">molecular markers</a>, <a href="https://publications.waset.org/abstracts/search?q=crop%20productivity" title=" crop productivity"> crop productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20diversity" title=" genetic diversity"> genetic diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=genotype" title=" genotype"> genotype</a> </p> <a href="https://publications.waset.org/abstracts/69621/application-of-molecular-markers-for-crop-improvement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69621.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">517</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">877</span> Bioactive Chemical Markers Based Strategy for Quality Control of Herbal Medicines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhenzhong%20Yang">Zhenzhong Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Herbal medicines are important supplements to chemical drugs and usually consist of a complex mixture of constituents. The current quality control strategy of herbal medicines is mainly based on chemical markers, which largely failed to owe to the markers, not reflecting the herbal medicines’ multiple mechanisms of action. Herein, a bioactive chemical markers based strategy was proposed and applied to the quality assessment and control of herbal medicines. This strategy mainly includes the comprehensive chemical characterization of herbal medicines, bioactive chemical markers identification, and related quantitative analysis methods development. As a proof-of-concept, this strategy was applied to a Panax notoginseng derived herbal medicine.

In order to estimate the genetic diversity, molecular markers provided excellent tools. In this study, Genetic variation of nine Egyptian jojoba shrubs was tested using ISSR (inter simple sequences repeats), RAPD (random amplified polymorphic DNA) markers and based on the morphological characterization. The average of the percentage of polymorphism (%P) ranged between 58.17% and 74.07% for ISSR and RAPD markers, respectively. The range of genetic similarity percents among shrubs based on ISSR and RAPD markers were from 82.9 to 97.9% and from 85.5 to 97.8%, respectively. The average of PIC (polymorphism information content) values were 0.19 (ISSR) and 0.24 (RAPD). In the present study, RAPD markers were more efficient than the ISSR markers. Where the RAPD technique exhibited higher marker index (MI) average (1.26) compared to ISSR one (1.11). There was an insignificant correlation between the ISSR and RAPD data (0.076, P > 0.05). The dendrogram constructed by the combined RAPD and ISSR data gave a relatively different clustering pattern. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=correlation" title="correlation">correlation</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20markers" title=" molecular markers"> molecular markers</a>, <a href="https://publications.waset.org/abstracts/search?q=polymorphism" title=" polymorphism"> polymorphism</a>, <a href="https://publications.waset.org/abstracts/search?q=marker%20index" title=" marker index"> marker index</a> </p> <a href="https://publications.waset.org/abstracts/22213/comparative-assessment-of-issr-and-rapd-markers-among-egyptian-jojoba-shrubs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22213.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">478</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">874</span> An Analysis of Discourse Markers Awareness in Writing Undergraduate Thesis of English Education Student in Sebelas Maret University</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oktanika%20Wahyu%20Nurjanah">Oktanika Wahyu Nurjanah</a>, <a href="https://publications.waset.org/abstracts/search?q=Anggun%20Fitriana%20Dewi"> Anggun Fitriana Dewi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An undergraduate thesis is one of the academic writings which should fulfill some characteristics, one of them is coherency. Moreover, a coherence of a text depends on the usage of discourse markers. In other word, discourse markers take an essential role in writing. Therefore, the researchers aim to know the awareness of the discourse markers usage in writing the under-graduate thesis of an English Education student at Sebelas Maret University. This research uses a qualitative case study in order to obtain a deep analysis. The sample of this research is an under-graduate thesis of English Education student in Sebelas Maret University which chosen based on some criteria. Additionally, the researchers were guided by some literature attempted to group the discourse markers based on their functions. Afterward, the analysis was held based on it. From the analysis, it found that the awareness of discourse markers usage is moderate. The last point, the researcher suggest undergraduate students to familiarize themselves with discourse markers, especially for those who want to write thesis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=discourse%20markers" title="discourse markers">discourse markers</a>, <a href="https://publications.waset.org/abstracts/search?q=English%20education" title=" English education"> English education</a>, <a href="https://publications.waset.org/abstracts/search?q=thesis%20writing" title=" thesis writing"> thesis writing</a>, <a href="https://publications.waset.org/abstracts/search?q=undergraduate%20student" title=" undergraduate student"> undergraduate student</a> </p> <a href="https://publications.waset.org/abstracts/60370/an-analysis-of-discourse-markers-awareness-in-writing-undergraduate-thesis-of-english-education-student-in-sebelas-maret-university" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60370.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">357</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">873</span> The Simultaneous Application of Chemical and Biological Markers to Identify Reliable Indicators of Untreated Human Waste and Fecal Pollution in Urban Philadelphia Source Waters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stafford%20Stewart">Stafford Stewart</a>, <a href="https://publications.waset.org/abstracts/search?q=Hui%20Yu"> Hui Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Rominder%20Suri"> Rominder Suri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper publishes the results of the first known study conducted in urban Philadelphia waterways that simultaneously utilized anthropogenic chemical and biological markers to identify suitable indicators of untreated human waste and fecal pollution. A total of 13 outfall samples, 30 surface water samples, and 2 groundwater samples were analyzed for fecal contamination and untreated human waste using a suite of 25 chemical markers and 5 bio-markers. Pearson rank correlation tests were conducted to establish associations between the abundances of bio-markers and the concentrations of chemical markers. Results show that 16S rRNA gene of human-associated Bacteroidales (BacH) was very strongly correlated (0.76 – 0.97, p < 0.05) with labile chemical markers acetaminophen, cotinine, estriol, and urobilin. Likewise, human-specific F- RNA coliphages (F-RNA-II) and labile chemical markers, urobilin, ibuprofen, cotinine and estriol, were significantly correlated (0.77 – 0.95, p < 0.05). Similarly, a strong positive correlation (0.67 – 0.91, p < 0.05) was evident between the abundances of bio-markers BacH and F-RNA-II, and the concentrations of the conservative markers, trimethoprim, meprobamate, diltiazem, triclocarban, metformin, sucralose, gemfibrozil, sulfamethoxazole, and carbamazepine. Human mitochondrial DNA (MitoH) correlated moderately with labile markers nicotine and salicylic acid as well as with conservative markers metformin and triclocarban (0.31 – 0.47, p<0.05). This study showed that by associating chemical and biological markers, a robust technique was developed for fingerprinting source-specific untreated waste and fecal contamination in source waters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anthropogenic%20markers" title="anthropogenic markers">anthropogenic markers</a>, <a href="https://publications.waset.org/abstracts/search?q=bacteroidales" title=" bacteroidales"> bacteroidales</a>, <a href="https://publications.waset.org/abstracts/search?q=fecal%20pollution" title=" fecal pollution"> fecal pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=source%20waters" title=" source waters"> source waters</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater" title=" wastewater"> wastewater</a> </p> <a href="https://publications.waset.org/abstracts/192663/the-simultaneous-application-of-chemical-and-biological-markers-to-identify-reliable-indicators-of-untreated-human-waste-and-fecal-pollution-in-urban-philadelphia-source-waters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192663.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">15</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">872</span> A Contrastive Rhetoric Study: The Use of Textual and Interpersonal Metadiscoursal Markers in Persian and English Newspaper Editorials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Habibollah%20Mashhady">Habibollah Mashhady</a>, <a href="https://publications.waset.org/abstracts/search?q=Moslem%20Fatollahi"> Moslem Fatollahi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study tries to contrast the use of metadiscoursal markers in English and Persian Newspaper Editorials as persuasive text types. These markers are linguistic elements in the text which do not add to the propositional content of it, rather they serve to realize the Halliday’s (1985) textual and interpersonal functions of language. At first, some of the most common markers from five subcategories of Text Connectives, Illocution Markers, Hedges, Emphatics, and Attitude Markers were identified in both English and Persian newspapers. Then, the frequency of occurrence of these markers in both English and Persian corpus consisting of 44 randomly selected editorials (18,000 words in each) from several English and Persian newspapers was recorded. After that, using a two-way chi square analysis, the overall x2 obs was found to be highly significant. So, the null hypothesis of no difference was confidently rejected. Finally, in order to determine the contribution of each subcategory to the overall x 2 value, one-way chi square analyses were applied to the individual subcategories. The results indicated that only two of the five subcategories of markers were statistically significant. This difference is then attributed to the differing spirits prevailing in the linguistic communities involved. Regarding the minor research question it was found that, in contrast to English writers, Persian writers are more writer-oriented in their writings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metadiscoursal%20markers" title="metadiscoursal markers">metadiscoursal markers</a>, <a href="https://publications.waset.org/abstracts/search?q=textual%20meta-function" title=" textual meta-function"> textual meta-function</a>, <a href="https://publications.waset.org/abstracts/search?q=interpersonal%20meta-function" title=" interpersonal meta-function"> interpersonal meta-function</a>, <a href="https://publications.waset.org/abstracts/search?q=persuasive%20texts" title=" persuasive texts"> persuasive texts</a>, <a href="https://publications.waset.org/abstracts/search?q=English%20and%20Persian%20newspaper%20editorials" title=" English and Persian newspaper editorials"> English and Persian newspaper editorials</a> </p> <a href="https://publications.waset.org/abstracts/18633/a-contrastive-rhetoric-study-the-use-of-textual-and-interpersonal-metadiscoursal-markers-in-persian-and-english-newspaper-editorials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18633.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">574</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">871</span> Impregnation Reduction Method for the Preparation of Platinum-Nickel/Carbon Black Alloy Nanoparticles as Faor Electrocatalyst</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Kiani">Maryam Kiani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to enhance the efficiency and stability of an electrocatalyst for formic acid electro-oxidation reaction (FAOR), we developed a method to create Pt/Ni nanoparticles with carbon black. These nanoparticles were prepared using a simple impregnation reduction technique. During the observation, it was found that the nanoparticles had a spherical shape. Additionally, the average particle size remained consistent, falling within the range of about 4 nm. This approach aimed to obtain a loaded Pt-based electrocatalyst that would exhibit improved performance and stability when used in FAOR applications. By utilizing the impregnation reduction method and incorporating Ni nanoparticles along with Pt, we sought to enhance the catalytic properties of the material. By incorporating Ni atoms into the Pt structure, the electronic properties of Pt are modified, resulting in a delay in the chemisorption of harmful CO intermediate species. This modification also promotes the dehydrogenation pathway of the formic acid oxidation reaction (FAOR). Through electrochemical analysis, it has been observed that the Pt3Ni-C catalyst exhibits enhanced performance in FAOR compared to traditional Pt catalysts. This means that the addition of Ni atoms improves the efficiency and effectiveness of the Pt3Ni-C catalyst in facilitating the FAOR process. Overall, the utilization of these alloy nanoparticles as electrocatalysts represents a significant advancement in fuel cell technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrocatalyst" title="electrocatalyst">electrocatalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=impregnation%20reduction%20method" title=" impregnation reduction method"> impregnation reduction method</a>, <a href="https://publications.waset.org/abstracts/search?q=formic%20acid%20electro-oxidation%20reaction" title=" formic acid electro-oxidation reaction"> formic acid electro-oxidation reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20cells" title=" fuel cells"> fuel cells</a> </p> <a href="https://publications.waset.org/abstracts/173326/impregnation-reduction-method-for-the-preparation-of-platinum-nickelcarbon-black-alloy-nanoparticles-as-faor-electrocatalyst" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173326.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">127</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">870</span> Exploring the Use of Discourse Markers by American Male and Female Politicians: A Corpus Based Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gohar%20Rahman">Gohar Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Rabia%20Saad%20Ullah"> Rabia Saad Ullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research aims to examine the use of discourse markers within the dominion of political speeches, differentiating between genders. The analysis centers on twelve speakers, comprising six males and six females. Speeches selected include commencement, victory, state union addresses, campaigns, and presidential speeches. Halliday and Hasan's cohesion framework, specifically discourse markers, is utilized as a theoretical framework. Data is quantitatively analyzed using AntConc to identify marker frequency. The findings are presented through Excel's tables and graphs, suggesting differences in discourse marker preferences between genders. The findings suggest a divergence in the preferences for discourse markers between males and females. However, asserting that females utilize discourse markers more frequently due to the increased use of filler words, face threat mitigation, and polite speech would be an exaggeration. The disparity in frequency is not substantial, suggesting that males and females exhibit varying language inclinations to some degree. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=discourse%20markers" title="discourse markers">discourse markers</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20discourse" title=" political discourse"> political discourse</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a>, <a href="https://publications.waset.org/abstracts/search?q=speeches" title=" speeches"> speeches</a>, <a href="https://publications.waset.org/abstracts/search?q=language" title=" language"> language</a> </p> <a href="https://publications.waset.org/abstracts/177467/exploring-the-use-of-discourse-markers-by-american-male-and-female-politicians-a-corpus-based-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177467.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">57</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">869</span> An Examination of Self-Mentions and Engagement Markers on the Academic IELTS Reading Exam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hilda%20Freimuth">Hilda Freimuth</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study examined the interactional resources of self-mentions and engagement markers in twenty official IELTS reading exam passages to determine the passages’ similarity to academic research papers.

Materials and Methods: The study consists of the clinical part of the measurement of inflammatory markers of 23 patients diagnosed with chronic periodontitis and the recording of parental periodontal parameters of patient periodontal status: hemorrhage index and probe values, before and 7-10 days after non-surgical periodontal treatment. Results: The level of fibrinogen drops according to the categorization of disease progression, active and passive, with the biggest % (18%-30%) at the fluctuation 10-20 mg/d. Fluctuations in fibrinogen level according to the age of patients in the range 0-10 mg/dL under 40 years and over 40 years was 13%-26%, in the range 10-20 mg/dL was 26%-22%, in the 20-40 mg/dL was 9%-4%. Conclusions: Non-surgical periodontal treatment significantly reduces the level of non-inflammatory markers in the blood. Oral health significantly reduces the potential source for periodontal bacteria, with the potential of promoting thromboembolism, through interaction between thrombocytes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chronic%20periodontitis" title="chronic periodontitis">chronic periodontitis</a>, <a href="https://publications.waset.org/abstracts/search?q=atherosclerosis" title=" atherosclerosis"> atherosclerosis</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factor" title=" risk factor"> risk factor</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammatory%20markers" title=" inflammatory markers "> inflammatory markers </a> </p> <a href="https://publications.waset.org/abstracts/116737/inflammatory-markers-in-the-blood-and-chronic-periodontitis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116737.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">126</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">866</span> Investigation of Genetic Diversity in Bread Wheat by RAPD and SSR Markers </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Sadegh%20Khavarinejad">Mohammad Sadegh Khavarinejad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, genetic diversity of 10 bread wheat genotypes by SSR and RAPD markers was evaluated. 11 primers were used included 6 RAPD primers and 5 SSR primers.

The paper uses the qualitative approach and relevance theory by Sperber and Wilson (1995) to highlight and examine DMs in different communicative contexts. In the course of data collection, five (5) academic staff from the five faculties of the university who are already Facebook friends of the researcher are used as the participants with their consent. The paper examines the communicative functions of English DMs among UMYUK academic staff on Facebook and reveals a number of communicative functions used in different contexts. One of the major findings indicates that 'contrastive markers' such as 'but', 'however', 'although' etc. are the dominant communicative functions employed by UMYUK academic staff on Facebook with 42% occurrence; it also shows that a single DM can function differently in the same linguistic environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=role" title="role">role</a>, <a href="https://publications.waset.org/abstracts/search?q=communicative" title=" communicative"> communicative</a>, <a href="https://publications.waset.org/abstracts/search?q=discourse%20markers" title=" discourse markers"> discourse markers</a>, <a href="https://publications.waset.org/abstracts/search?q=facebook" title=" facebook"> facebook</a>, <a href="https://publications.waset.org/abstracts/search?q=academic%20staff" title=" academic staff"> academic staff</a> </p> <a href="https://publications.waset.org/abstracts/131862/communicative-roles-of-english-discourse-markers-on-facebook-among-umaru-musa-yaradua-university-members-of-academic-staff" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131862.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">169</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">864</span> Analyses of Copper Nanoparticles Impregnated Wood and Its Fungal Degradation Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Graciela%20Aguayo">María Graciela Aguayo</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Reyes"> Laura Reyes</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Oviedo"> Claudia Oviedo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Navarrete"> José Navarrete</a>, <a href="https://publications.waset.org/abstracts/search?q=Liset%20G%C3%B3mez"> Liset Gómez</a>, <a href="https://publications.waset.org/abstracts/search?q=Hugo%20Torres"> Hugo Torres</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Most wood species used in construction deteriorate when exposed to environmental conditions that favor wood-degrading organisms’ growth. Therefore, chemical protection by impregnation allows more efficient use of forest resources extending the wood useful life. A wood protection treatment which has attracted considerable interest in the scientific community during the last decade is wood impregnation with nano compounds. Radiata pine is the main wood species used in the Chilean construction industry, with total availability of 8 million m³ sawn timber. According to the requirements of the American Wood Protection Association (AWPA) and the Chilean Standards (NCh) radiata pine timber used in construction must be protected due to its low natural durability. In this work, the impregnation with copper nanoparticles (CuNP) was studied in terms of penetration and its protective effect against wood rot fungi. Two concentrations: 1 and 3 g/L of NPCu were applied by impregnation on radiata pine sapwood. Test penetration under AWPA A3-91 standard was carried out, and wood decay tests were performed according to EN 113, with slight modifications. The results of penetration for 1 g/L CuNP showed an irregular total penetration, and the samples impregnated with 3 g/L showed a total penetration with uniform concentration (blue color in all cross sections). The impregnation wood mass losses due to fungal exposure were significantly reduced, regardless of the concentration of the solution or the fungus. In impregnated wood samples, exposure to G. trabeum resulted ML values of 2.70% and 1.19% for 1 g/L and 3 g/L CuNP, respectively, and exposure to P. placenta resulted in 4.02% and 0.70%-ML values for 1 g/L and 3 g/L CuNP, respectively. In this study, the penetration analysis confirmed a uniform distribution inside the wood, and both concentrations were effective against the tested fungi, giving mass loss values lower than 5%. Therefore, future research in wood preservatives should focus on new nanomaterials that are more efficient and environmentally friendly.

Growth of the cell cultures was accessed under microscopic evaluation in transmitted light and the marker expression by reverse polymerase chain reaction (RT-PCR), immunofluorescence, and immunoblotting. Some PCR products from prostate tissue, PSCC, and PDO were cloned and sequenced. We found that the cells of early and late passages of PSCC and corresponding PDO expressed luminal (androgen receptor, AR; cytokeratin 18, CK18) and basal (CK5, p63) epithelial markers, the production of which decreased or disappeared in late PSCC and PDO. The PSCC and PDO of early passages from cancer tissue additionally produced cancer markers AMACR, TMPRSS2-ERG, and Ezh2. The expression of TMPRSS2-ERG fusion transcripts was verified by cloning and sequencing the PCR products. The results obtained suggest that early passages of PSCC might be used as a pre-clinical model for the evaluation of early markers of prostate cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=localized%20prostate%20cancer" title="localized prostate cancer">localized prostate cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=prostate%20epithelial%20markers" title=" prostate epithelial markers"> prostate epithelial markers</a>, <a href="https://publications.waset.org/abstracts/search?q=prostate%20cancer%20markers" title=" prostate cancer markers"> prostate cancer markers</a>, <a href="https://publications.waset.org/abstracts/search?q=AMACR" title=" AMACR"> AMACR</a>, <a href="https://publications.waset.org/abstracts/search?q=TMPRSS2-ERG" title=" TMPRSS2-ERG"> TMPRSS2-ERG</a>, <a href="https://publications.waset.org/abstracts/search?q=prostate%20stromal%20cell%20cultures" title=" prostate stromal cell cultures"> prostate stromal cell cultures</a>, <a href="https://publications.waset.org/abstracts/search?q=PDO" title=" PDO"> PDO</a> </p> <a href="https://publications.waset.org/abstracts/153032/early-cell-cultures-derived-from-human-prostate-cancer-tissue-express-tissue-specific-epithelial-and-cancer-markers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153032.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">108</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">862</span> Atomic Layer Deposition of MoO₃ on Mesoporous γ-Al₂O₃ Prepared by Sol-Gel Method as Efficient Catalyst for Oxidative Desulfurization of Refractory Dibenzothiophene Compound</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Said">S.

In this context, 4 & 9wt.% MoO₃ grafted on mesoporous γ-Al₂O₃ has been synthesized using the modified atomic layer deposition (ALD) method. Another MoO₃/Al₂O₃ sample was prepared by the conventional wetness impregnation (IM) method, for comparison. The effect of the preparation methods on the metal-support interaction was evaluated using different characterization techniques, including X-ray diffraction, X-ray photoelectron spectroscopy (XPS), N₂-physisorption, transmission electron microscopy (TEM), H₂- temperature-programmed reduction and FT-IR. Oxidative desulfurization (ODS) reaction of the model fuel oil was used as a probe reaction to examine the catalytic efficiency of the prepared catalysts. ALD method led to samples with much better physicochemical properties than those of the prepared one via the impregnation method. However, the 9 wt.%MoO₃/Al₂O₃ (ALD) catalyst in the ODS reaction of model fuel oil shows enhanced catalytic performance with ~90%, which has been attributed to the more Mo⁶⁺ surface concentrations relative to Al³⁺ with large pore diameter and surface area. The kinetic study shows that the ODS of DBT follows a pseudo first-order rate reaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mesoporous%20Al%E2%82%82O%E2%82%83" title="mesoporous Al₂O₃">mesoporous Al₂O₃</a>, <a href="https://publications.waset.org/abstracts/search?q=xMoO%E2%82%83%2FAl%E2%82%82O%E2%82%83" title=" xMoO₃/Al₂O₃"> xMoO₃/Al₂O₃</a>, <a href="https://publications.waset.org/abstracts/search?q=atomic%20layer%20deposition" title=" atomic layer deposition"> atomic layer deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=wetness%20impregnation" title=" wetness impregnation"> wetness impregnation</a>, <a href="https://publications.waset.org/abstracts/search?q=ODS" title=" ODS"> ODS</a>, <a href="https://publications.waset.org/abstracts/search?q=DBT" title=" DBT"> DBT</a> </p> <a href="https://publications.waset.org/abstracts/118237/atomic-layer-deposition-of-moo3-on-mesoporous-gh-al2o3-prepared-by-sol-gel-method-as-efficient-catalyst-for-oxidative-desulfurization-of-refractory-dibenzothiophene-compound" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118237.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">105</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">861</span> Characterization of Some Bread Wheat Genotypes for Drought Tolerance Using Molecular Markers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Beg%C3%BCm%20Terzi">Begüm Terzi</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96zlem%20Ate%C5%9F%20S%C3%B6nmezo%C4%9Flu"> Özlem Ateş Sönmezoğlu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20Yildirim"> Ahmet Yildirim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Drought is the most important factor that limiting the production and productivity of wheat in the world. The yield of wheat, which is one of the most important crop in the world, reduced depend on drought. Researches to minimize effects of drought are one of the most important about breeding of drought resistant varieties. In recent years, benefiting from the drought resistance wild species and rapid advances in molecular biology studies, researches about drought have been accelerated and number of studies were made on molecular plant breeding which included the molecular mechanisms related to drought resistance. The aim of the present study was characterization of some bread wheat lines for drought tolerance which commonly cultivated in different location of Turkey. In this study, registered 9 bread wheat varieties which on the physiological tests about drought tolerance and 10 bread wheat line has been developed by Transitional Zone Agricultural Research Institute were used. SSR, STS, RAPD and SNP markers that associated with drought tolerance were used. The polymorphisms of the markers were determined by screening of two control varieties. For these purpose 40 molecular markers were used and 12 markers of them were polymorphic among the drought tolerance and the drought sensitive varieties. Control varieties were screened using polymorphic markers. All the DNAs on the genotypes will be searched for the presence of QTLs mapped to different chromosomes. Result of the research, the studied genotypes will be grouped according to drought tolerance and will be detected drought tolerance varieties by molecular markers. In addition, the results will be compared also with physiological tests. The drought tolerant wheat genotypes may be used in breeding studies related to drought stress. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bread%20wheat" title="bread wheat">bread wheat</a>, <a href="https://publications.waset.org/abstracts/search?q=drought" title=" drought"> drought</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20marker" title=" molecular marker"> molecular marker</a>, <a href="https://publications.waset.org/abstracts/search?q=Triticum%20aestivum" title=" Triticum aestivum"> Triticum aestivum</a> </p> <a href="https://publications.waset.org/abstracts/49403/characterization-of-some-bread-wheat-genotypes-for-drought-tolerance-using-molecular-markers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49403.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">385</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">860</span> CD133 and CD44 - Stem Cell Markers for Prediction of Clinically Aggressive Form of Colorectal Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ognen%20Kostovski">Ognen Kostovski</a>, <a href="https://publications.waset.org/abstracts/search?q=Svetozar%20Antovic"> Svetozar Antovic</a>, <a href="https://publications.waset.org/abstracts/search?q=Rubens%20%20Jovanovic"> Rubens Jovanovic</a>, <a href="https://publications.waset.org/abstracts/search?q=Irena%20%20Kostovska"> Irena Kostovska</a>, <a href="https://publications.waset.org/abstracts/search?q=Nikola%20Jankulovski"> Nikola Jankulovski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction:Colorectal carcinoma (CRC) is one of the most common malignancies in the world. The cancer stem cell (CSC) markers are associated with aggressive cancer types and poor prognosis. The aim of study was to determine whether the expression of colorectal cancer stem cell markers CD133 and CD44 could be significant in prediction of clinically aggressive form of CRC. Materials and methods: Our study included ninety patients (n=90) with CRC. Patients were divided into two subgroups: with metatstatic CRC and non-metastatic CRC. Tumor samples were analyzed with standard histopathological methods, than was performed immunohistochemical analysis with monoclonal antibodies against CD133 and CD44 stem cell markers. Results: High coexpression of CD133 and CD44 was observed in 71.4% of patients with metastatic disease, compared to 37.9% in patients without metastases. Discordant expression of both markers was found in 8% of the subgroup with metastatic CRC, and in 13.4% of the subgroup without metastatic CRC. Statistical analyses showed a significant association of increased expression of CD133 and CD44 with the disease stage, T - category and N - nodal status. With multiple regression analysis the stage of disease was designate as a factor with the greatest statistically significant influence on expression of CD133 (p <0.0001) and CD44 (p <0.0001). Conclusion: Our results suggest that the coexpression of CD133 and CD44 have an important role in prediction of clinically aggressive form of CRC. Both stem cell markers can be routinely implemented in standard pathohistological diagnostics and can be useful markers for pre-therapeutic oncology screening. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=colorectal%20carcinoma" title="colorectal carcinoma">colorectal carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=stem%20cells" title=" stem cells"> stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=CD133%2B" title=" CD133+"> CD133+</a>, <a href="https://publications.waset.org/abstracts/search?q=CD44%2B" title=" CD44+"> CD44+</a> </p> <a href="https://publications.waset.org/abstracts/119672/cd133-and-cd44-stem-cell-markers-for-prediction-of-clinically-aggressive-form-of-colorectal-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119672.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">150</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">859</span> Effect of High-Pressure and Thermal Treatments on Quality Markers of Strawberry Nectars</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karen%20Louise%20Lacey">Karen Louise Lacey</a>, <a href="https://publications.waset.org/abstracts/search?q=Dario%20Javier%20Pavon%20Vargas"> Dario Javier Pavon Vargas</a>, <a href="https://publications.waset.org/abstracts/search?q=Massimiliano%20Rinaldi"> Massimiliano Rinaldi</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Cattani"> Luca Cattani</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Rainieri"> Sara Rainieri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effects of high-pressure processing (HPP) and thermal treatments (TT) on quality markers of strawberry nectar (12 °Brix, 3,3 pH) was studied before and after treatments.

As it causes serious danger to trees, the beetle has been paid close attention in the world. However, the genetic markers limited, especially microsatellite. In this study, 24 novel simple sequence repeat (SSR) molecular markers, a powerful tool for genetic diversity studies and linkage map construction, were developed and characterized from whole genome shotgun sequences. We developed SSR loci of 2 to 6 repeated and perfect units including 9895 points, the density of SSRs was found one SSR per 56.57 kb and the abundance of SSR was 0.02/kb, besides 140 types of repeats motifs were found. Half of the 48 pairs SSR primers (containing 4 di-, 7 tri-, 2 tetra- and 11 hexamers SSRs) we selected randomly from 1222 pairs of primers were polymorphism. The number of alleles for these markers in 48 individuals varied from 3 to 21 with an average of 7.71, the number of effective alleles ranged from 1.22 to 9.97 with an average of 3.54. Besides this, the polymorphic information content (PIC) ranged from 0.18 to 0.89 with a mean of 0.65, And Shannon's Information index (I) ranged from 0.46 to 2.62 with an average of 1.44. The results suggest that the method for screening of SSR in the whole genome is feasible and efficient. SSR markers developed in this study can be used for population genetic studies of A. glabripennis. Moreover, they may also be helpful for the development of microsatellites for other Coleoptera. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SSR%20markers" title="SSR markers">SSR markers</a>, <a href="https://publications.waset.org/abstracts/search?q=Anoplophora%20glabripennis" title=" Anoplophora glabripennis"> Anoplophora glabripennis</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20diversity" title=" genetic diversity"> genetic diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=whole%20genome" title=" whole genome"> whole genome</a> </p> <a href="https://publications.waset.org/abstracts/31940/development-and-characterization-of-polymorphic-genomic-ssr-markers-in-asian-long-horned-beetle-anoplophora-glabripennis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31940.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">389</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">857</span> Molecular Characterization of Polyploid Bamboo (Dendrocalamus hamiltonii) Using Microsatellite Markers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajendra%20K.%20Meena">Rajendra K.

Since it is codominant and allelic markers, utilizing them in polyploid species remained doubtful. In such cases, the microsatellite marker is usually analyzed by treating them as a dominant marker. In the current study, it has been showed that despite losing the advantage of co-dominance, microsatellite markers are still a powerful tool for genotyping of polyploid species because of availability of large number of reproducible alleles per locus. It has been studied by genotyping of 19 subpopulations of Dendrocalamus hamiltonii (hexaploid bamboo species) with 17 polymorphic simple sequence repeat (SSR) primer pairs. Among these, ten primers gave typical banding pattern of microsatellite marker as expected in diploid species, but rest 7 gave an unusual pattern, i.e., more than two bands per locus per genotype. In such case, genotyping data are generally analyzed by considering as dominant markers. In the current study, data were analyzed in both ways as dominant and co-dominant. All the 17 primers were first scored as nonallelic data and analyzed; later, the ten primers giving standard banding patterns were analyzed as allelic data and the results were compared. The UPGMA clustering and genetic structure showed that results obtained with both the data sets are very similar with slight variation, and therefore the SSR marker could be utilized to characterize polyploid species by considering them as a dominant marker. The study is highly useful to widen the scope for SSR markers applications and beneficial to the researchers dealing with polyploid species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microsatellite%20markers" title="microsatellite markers">microsatellite markers</a>, <a href="https://publications.waset.org/abstracts/search?q=Dendrocalamus%20hamiltonii" title=" Dendrocalamus hamiltonii"> Dendrocalamus hamiltonii</a>, <a href="https://publications.waset.org/abstracts/search?q=dominant%20and%20codominant" title=" dominant and codominant"> dominant and codominant</a>, <a href="https://publications.waset.org/abstracts/search?q=polyploids" title=" polyploids"> polyploids</a> </p> <a href="https://publications.waset.org/abstracts/116652/molecular-characterization-of-polyploid-bamboo-dendrocalamus-hamiltonii-using-microsatellite-markers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116652.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">143</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">856</span> Phylogenetic Relationships between the Whole Sets of Individual Flow Sorted U, M, S and C Chromosomes of Aegilops and Wheat as Revealed by COS Markers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A1s%20Farkas">András Farkas</a>, <a href="https://publications.waset.org/abstracts/search?q=Istv%C3%A1n%20Moln%C3%A1r"> István Molnár</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Vr%C3%A1na"> Jan Vrána</a>, <a href="https://publications.waset.org/abstracts/search?q=Veronika%20Bure%C5%A1ov%C3%A1"> Veronika Burešová</a>, <a href="https://publications.waset.org/abstracts/search?q=Petr%20C%C3%A1pal"> Petr Cápal</a>, <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A1s%20Cseh"> András Cseh</a>, <a href="https://publications.waset.org/abstracts/search?q=M%C3%A1rta%20Moln%C3%A1r-L%C3%A1ng"> Márta Molnár-Láng</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaroslav%20Dole%C5%BEel"> Jaroslav Doležel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Species of Aegilops played a central role in the evolution of wheat and are sources of traits related to yield quality and tolerance against biotic and abiotic stresses. These wild genes and alleles are desirable to use in crop improvement programs via introgressive hybridization. However, the success of chromosome mediated gene transfer to wheat are hampered by the pour knowledge on the genome structure of Aegilops relative to wheat and by the low number of cost-effective molecular markers specific for Aegilops chromosomes. The COS markers specific for genes conserved throughout evolution in both sequence and copy number between Triticeae/Aegilops taxa and define orthologous regions, thus enabling the comparison of regions on the chromosomes of related species. The present study compared individual chromosomes of Aegilops umbellulata (UU), Ae. comosa (MM), Ae. speltoides (SS) and Ae. caudata (CC) purified by flourescent labelling with oligonucleotid SSR repeats and biparametric flow cytometry with wheat by identifying orthologous chromosomal regions by COS markers. The linear order of bin-mapped COS markers along the wheat D chromosomes was identified by the use of chromosome-specific sequence data and virtual gene order. Syntenic regions of wheat identifying genome rearrangements differentiating the U, M, S or C genomes from the D genome of wheat were detected. The conserved orthologous set markers assigned to Aegilops chromosomes promise to accelerate gene introgression by facilitating the identification of alien chromatin. The syntenic relationships between the Aegilops species and wheat will facilitate the targeted development of new markers specific for U, M, S and C genomic regions and will contribute to the understanding of molecular processes related to the evolution of Aegilops. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aegilops" title="Aegilops">Aegilops</a>, <a href="https://publications.waset.org/abstracts/search?q=cos-markers" title=" cos-markers"> cos-markers</a>, <a href="https://publications.waset.org/abstracts/search?q=flow-sorting" title=" flow-sorting"> flow-sorting</a>, <a href="https://publications.waset.org/abstracts/search?q=wheat" title=" wheat"> wheat</a> </p> <a href="https://publications.waset.org/abstracts/29629/phylogenetic-relationships-between-the-whole-sets-of-individual-flow-sorted-u-m-s-and-c-chromosomes-of-aegilops-and-wheat-as-revealed-by-cos-markers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29629.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">502</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">855</span> Implementation of Metabolomics in Conjunction with Chemometrics for the Dentification of the Differential Chemical Markers of Different Grades of Sri Lankan White, Green and Black Tea: Camellia Sinenesis L.</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dina%20A.%20Selim">Dina A.

Two types of carbon woven fabric structures were investigated: standard type, which integrated the filament, has a cross sectional shape of a cylinder and spread tow type, which has a rectangular cross sectional shape. The space antennas reflector, which distinctive feature is the presence of the surface of double curvature, is considered as the object of the research. Modeling of the kinetics of the process of impregnation of the reflector for the two types of carbon fabric’s unit cell structures was performed using software RAM-RTM. This work also investigated the influence of the grid angle between warp and welt of the unit cell on the duration of impregnation process. The results showed that decreasing the angle between warp and welt of the unit cell, the decreasing of the permeability values were occurred. Based on the results of calculation samples of the reflectors, their quality was determined. The comparisons of the theoretical and experimental results have been carried out. Comparison of the two textile structures (standard and spread tow) showed that the standard textiles with circular cross section were impregnated faster than spread tows, which have a rectangular cross section. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vacuum%20assistant%20resin%20infusion" title="vacuum assistant resin infusion">vacuum assistant resin infusion</a>, <a href="https://publications.waset.org/abstracts/search?q=impregnation%20time" title=" impregnation time"> impregnation time</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20angle" title=" shear angle"> shear angle</a>, <a href="https://publications.waset.org/abstracts/search?q=reflector%20and%20modeling" title=" reflector and modeling"> reflector and modeling</a> </p> <a href="https://publications.waset.org/abstracts/47083/technological-ensuring-of-the-space-reflector-antennas-manufacturing-process-from-carbon-fiber-reinforced-plastics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47083.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">273</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">853</span> Development of Microsatellite Markers for Genetic Variation Analysis in House Cricket, Acheta domesticus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yash%20M.%20Gupta">Yash M.

Although it is very commonly used as food and feed, the genomic information of house cricket is still missing for genetic investigation. DNA sequencing technology has evolved over the decades, and it has also revolutionized the molecular marker development for genetic analysis. In the present study, we have sequenced the whole genome of A. domesticus using illumina platform based HiSeq X Ten sequencing technology for searching simple sequence repeats (SSRs) in DNA to develop polymorphic microsatellite markers for population genetic analysis. A total of 112,157 SSRs with primer pairs were identified, 91 randomly selected SSRs used to check DNA amplification, of which nine primers were polymorphic. These microsatellite markers have shown cross-amplification with other three species of crickets which are Gryllus bimaculatus, Gryllus testaceus and Brachytrupes portentosus. These nine polymorphic microsatellite markers were used to check genetic variation for forty-five individuals of A. domesticus, Phitsanulok population, Thailand. For nine loci, the number of alleles was ranging from 5 to 15. The observed heterozygosity was ranged from 0.4091 to 0.7556. These microsatellite markers will facilitate population genetic analysis for future studies of A. domesticus populations. Moreover, the transferability of these SSR makers would also enable researchers to conduct genetic studies for other closely related species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross-amplification" title="cross-amplification">cross-amplification</a>, <a href="https://publications.waset.org/abstracts/search?q=microsatellite%20markers" title=" microsatellite markers"> microsatellite markers</a>, <a href="https://publications.waset.org/abstracts/search?q=observed%20heterozygosity" title=" observed heterozygosity"> observed heterozygosity</a>, <a href="https://publications.waset.org/abstracts/search?q=population%20genetic" title=" population genetic"> population genetic</a>, <a href="https://publications.waset.org/abstracts/search?q=simple%20sequence%20repeats" title=" simple sequence repeats"> simple sequence repeats</a> </p> <a href="https://publications.waset.org/abstracts/109733/development-of-microsatellite-markers-for-genetic-variation-analysis-in-house-cricket-acheta-domesticus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109733.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">142</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">852</span> Genetic Diversity Analysis in Triticum Aestivum Using Microsatellite Markers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prachi%20Sharma">Prachi Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Mukesh%20Kumar%20Rana"> Mukesh Kumar Rana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present study, the simple sequence repeat(SSR) markers have been used in analysis of genetic diversity of 37 genotypes of Triticum aestivum. The DNA was extracted using cTAB method. The DNA was quantified using the fluorimeter. The annealing temperatures for 27 primer pairs were standardized using gradient PCR, out of which 16 primers gave satisfactory amplification at temperature ranging from 50-62⁰ C. Out of 16 polymorphic SSR markers only 10 SSR primer pairs were used in the study generating 34 reproducible amplicons among 37 genotypes out of which 30 were polymorphic. Primer pairs Xgwm533, Xgwm 160, Xgwm 408, Xgwm 120, Xgwm 186, Xgwm 261 produced maximum percent of polymorphic bands (100%). The bands ranged on an average of 3.4 bands per primer. The genetic relationship was determined using Jaccard pair wise similarity co-efficient and UPGMA cluster analysis with NTSYS Pc.2 software. The values of similarity index range from 0-1. The similarity coefficient ranged from 0.13 to 0.97. A minimum genetic similarity (0.13) was observed between VL 804 and HPW 288, meaning they are only 13% similar. More number of available SSR markers can be useful for supporting the genetic diversity analysis in the above wheat genotypes. <p class="card-text"><strong>Keywords:</strong> <a
