Soil characterization needs to be determined by conducting several processes, especially permeability coefficient (<em>k</em>) in both saturated and unsaturated conditions to solve this problem. More accurate and efficient field testing procedure is required to obtain permeability data that present the field condition. One of the field permeability test equipment is Constant Discharge procedure to determine the permeability coefficient. Necessary adjustments of the Constant Discharge procedure are needed to be determined especially the value of geometric factor (<em>F</em>) to improve the corresponding value of permeability coefficient. The value of <em>k</em> will be correlated with the value of volumetric water content (<em>θ</em>) of an unsaturated condition until saturated condition. The principle procedure of Constant Discharge model provides a constant flow in permeameter tube that flows into the ground until the water level in the tube becomes constant. Constant water level in the tube is highly dependent on the tube dimension. Every tube dimension has a shape factor called the geometric factor that affects the result of the test. Geometric factor value is defined as the characteristic of shape and radius of the tube. This research has modified the geometric factor parameters by using empty material tube method so that the geometric factor will change. Saturation level is monitored by using soil moisture sensor. The field test results were compared with the results of laboratory tests to validate the results of the test. Field and laboratory test results of empty tube material method have an average difference of 3.33 x 10<sup>-4</sup> cm/sec. The test results showed that modified geometric factor provides more accurate data. The improved methods of constant discharge procedure provide more relevant results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constant%20discharge" title="constant discharge">constant discharge</a>, <a href="https://publications.waset.org/abstracts/search?q=geometric%20factor" title=" geometric factor"> geometric factor</a>, <a href="https://publications.waset.org/abstracts/search?q=permeability%20coefficient" title=" permeability coefficient"> permeability coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=unsaturated%20soils" title=" unsaturated soils"> unsaturated soils</a> </p> <a href="https://publications.waset.org/abstracts/53617/determination-of-unsaturated-soil-permeability-based-on-geometric-factor-development-of-constant-discharge-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53617.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">294</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">5244</span> Preparation of Low-Molecular-Weight 6-Amino-6-Deoxychitosan (LM6A6DC) for Immobilization of Growth Factor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Koo-Yeon%20Kim">Koo-Yeon Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Eun-Hye%20Kim"> Eun-Hye Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae-Il%20Son"> Tae-Il Son</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Epidermal Growth Factor (EGF, Mw=6,045) has been reported to have high efficiency of wound repair and anti-wrinkle effect. However, the half-life of EGF in the body is too short to exert the biological activity effectively when applied in free form. Growth Factors can be stabilized by immobilization with carbohydrates from thermal and proteolytic degradation. Low molecular weight chitosan (LMCS) and its derivate prepared by hydrogen peroxide has high solubility. LM6A6DC was successfully prepared as a reactive carbohydrate for the stabilization of EGF by the reactions of LMCS with alkalization, tosylation, azidation and reduction. The structure of LM6A6DC was confirmed by FT-IR, 1H NMR and elementary analysis. For enhancing the stability of free EGF, EGF was attached with LM6A6DC by using water-soluble carbodiimide. EGF-LM6A6DC conjugates did not show any cytotoxicity on the Normal Human Dermal Fibroblast(NHDF) 3T3 proliferation at least under 100 ㎍/㎖. In the result, it was considered that LM6A6DC is suitable to immobilize of growth factor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epidermal%20growth%20factor%20%28EGF%29" title="epidermal growth factor (EGF)">epidermal growth factor (EGF)</a>, <a href="https://publications.waset.org/abstracts/search?q=low-molecular-weight%20chitosan" title=" low-molecular-weight chitosan"> low-molecular-weight chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=immobilization" title=" immobilization"> immobilization</a> </p> <a href="https://publications.waset.org/abstracts/21422/preparation-of-low-molecular-weight-6-amino-6-deoxychitosan-lm6a6dc-for-immobilization-of-growth-factor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21422.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">473</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">5243</span> Structural Elucidation of Intact Rough-Type Lipopolysaccharides using Field Asymmetric Ion Mobility Spectrometry and Kendrick Mass Defect Plots</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abanoub%20Mikhael">Abanoub Mikhael</a>, <a href="https://publications.waset.org/abstracts/search?q=Darryl%20Hardie"> Darryl Hardie</a>, <a href="https://publications.waset.org/abstracts/search?q=Derek%20Smith"> Derek Smith</a>, <a href="https://publications.waset.org/abstracts/search?q=Helena%20Petrosova"> Helena Petrosova</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Ernst"> Robert Ernst</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Goodlett"> David Goodlett</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lipopolysaccharide (LPS) is a hallmark virulence factor of Gram-negative bacteria. It is a complex, structurally het- erogeneous mixture due to variations in number, type, and position of its simplest units: fatty acids and monosaccharides. Thus, LPS structural characterization by traditional mass spectrometry (MS) methods is challenging. Here, we describe the benefits of field asymmetric ion mobility spectrometry (FAIMS) for analysis of intact R-type lipopolysaccharide complex mixture (lipooligo- saccharide; LOS). Structural characterization was performed using Escherichia coli J5 (Rc mutant) LOS, a TLR4 agonist widely used in glycoconjugate vaccine research. FAIMS gas phase fractionation improved the (S/N) ratio and number of detected LOS species. Additionally, FAIMS allowed the separation of overlapping isobars facilitating their tandem MS characterization and un- equivocal structural assignments. In addition to FAIMS gas phase fractionation benefits, extra sorting of the structurally related LOS molecules was further accomplished using Kendrick mass defect (KMD) plots. Notably, a custom KMD base unit of [Na-H] created a highly organized KMD plot that allowed identification of interesting and novel structural differences across the different LOS ion families, i.e., ions with different acylation degrees, oligosaccharides composition, and chemical modifications. Defining the composition of a single LOS ion by tandem MS along with the organized KMD plot structural network was sufficient to deduce the composition of 181 LOS species out of 321 species present in the mixture. The combination of FAIMS and KMD plots allowed in-depth characterization of the complex LOS mixture and uncovered a wealth of novel information about its structural variations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lipopolysaccharide" title="lipopolysaccharide">lipopolysaccharide</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20mobility%20MS" title=" ion mobility MS"> ion mobility MS</a>, <a href="https://publications.waset.org/abstracts/search?q=Kendrick%20mass%20defect" title=" Kendrick mass defect"> Kendrick mass defect</a>, <a href="https://publications.waset.org/abstracts/search?q=Tandem%20mass%20spectrometry" title=" Tandem mass spectrometry"> Tandem mass spectrometry</a> </p> <a href="https://publications.waset.org/abstracts/173086/structural-elucidation-of-intact-rough-type-lipopolysaccharides-using-field-asymmetric-ion-mobility-spectrometry-and-kendrick-mass-defect-plots" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173086.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">71</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">5242</span> Comparison of Safety Factor Evaluation Methods for Buckling of High Strength Steel Welded Box Section Columns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Balazs%20Somodi">Balazs Somodi</a>, <a href="https://publications.waset.org/abstracts/search?q=Balazs%20Kovesdi"> Balazs Kovesdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the research praxis of civil engineering the statistical evaluation of experimental and numerical investigations is an essential task in order to compare the experimental and numerical resistances of a specific structural problem with the proposed resistances of the standards. However, in the standards and in the international literature there are several different safety factor evaluation methods that can be used to check the necessary safety level (e.g.: 5% quantile level, 2.3% quantile level, 1‰ quantile level, γM partial safety factor, γM* partial safety factor, β reliability index). Moreover, in the international literature different calculation methods could be found even for the same safety factor as well. In the present study the flexural buckling resistance of high strength steel (HSS) welded closed sections are analyzed. The authors investigated the flexural buckling resistances of the analyzed columns by laboratory experiments. In the present study the safety levels of the obtained experimental resistances are calculated based on several safety approaches and compared with the EN 1990. The results of the different safety approaches are compared and evaluated. Based on the evaluation tendencies are identified and the differences between the statistical evaluation methods are explained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flexural%20buckling" title="flexural buckling">flexural buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20strength%20steel" title=" high strength steel"> high strength steel</a>, <a href="https://publications.waset.org/abstracts/search?q=partial%20safety%20factor" title=" partial safety factor"> partial safety factor</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20evaluation" title=" statistical evaluation"> statistical evaluation</a> </p> <a href="https://publications.waset.org/abstracts/82296/comparison-of-safety-factor-evaluation-methods-for-buckling-of-high-strength-steel-welded-box-section-columns" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82296.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">160</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">5241</span> Design and Simulation of Low Threshold Nanowire Photonic Crystal Surface Emitting Lasers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Balthazar%20Temu">Balthazar Temu</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhao%20Yan"> Zhao Yan</a>, <a href="https://publications.waset.org/abstracts/search?q=Bogdan-Petrin%20Ratiu"> Bogdan-Petrin Ratiu</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang%20Soon%20Oh"> Sang Soon Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Qiang%20Li"> Qiang Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nanowire based Photonic Crystal Surface Emitting Lasers (PCSELs) reported in the literature have been designed using a triangular, square or honeycomb patterns. The triangular and square pattern PCSELs have limited degrees of freedom in tuning the design parameters which hinders the ability to design high quality factor (Q-factor) devices. Nanowire based PCSELs designed using triangular and square patterns have been reported with the lasing thresholds of 130 kW/〖cm〗^2 and 7 kW/〖cm〗^2 respectively. On the other hand the honeycomb pattern gives more degrees of freedom in tuning the design parameters, which can allow one to design high Q-factor devices. A deformed honeycomb pattern device was reported with lasing threshold of 6.25 W/〖cm〗^2 corresponding to a simulated Q-factor of 5.84X〖10〗^5.Despite this achievement, the design principles which can lead to realization of even higher Q-factor honeycomb pattern PCSELs have not yet been investigated. In this work we show that through deforming the honeycomb pattern and tuning the heigh and lattice constants of the nanowires, it is possible to achieve even higher Q-factor devices. Considering three different band edge modes, we investigate how the resonance wavelength changes as the device is deformed, which is useful in designing high Q-factor devices in different wavelength bands. We eventually establish the design and simulation of honeycomb PCSELs operating around the wavelength of 960nm , in the O and the C band with Q-factors up to 7X〖10〗^7. We also investigate the Q-factors of undeformed device, and establish that the mode at the band edge close to 960nm can attain highest Q-factor of all the modes when the device is undeformed and the Q-factor degrades as the device is deformed. This work is a stepping stone towards the fabrication of very high Q-factor, nanowire based honey comb PCSELs, which are expected to have very low lasing threshold. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=designing%20nanowire%20PCSEL" title="designing nanowire PCSEL">designing nanowire PCSEL</a>, <a href="https://publications.waset.org/abstracts/search?q=designing%20PCSEL%20on%20silicon%20substrates" title=" designing PCSEL on silicon substrates"> designing PCSEL on silicon substrates</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20threshold%20nanowire%20laser" title=" low threshold nanowire laser"> low threshold nanowire laser</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation%20of%20photonic%20crystal%20lasers" title=" simulation of photonic crystal lasers"> simulation of photonic crystal lasers</a> </p> <a href="https://publications.waset.org/abstracts/193552/design-and-simulation-of-low-threshold-nanowire-photonic-crystal-surface-emitting-lasers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193552.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">11</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">5240</span> Length Weight Relationship and Relative Condition Factor of Atropus atropos (Bloch and Schneider, 1801) from Mangalore Coast, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20P.%20Rajesh">D.

Therefore the present investigation was undertaken. Fish samples were collected from fish landing center (Mangalore) and fish market. The regression co-efficient of male was found to be lower than female. From this observation it may be opined that female gained more weight with increase in length compared to male. Data on seasonal variation in condition factor (Kn) showed that Kn values were more or less similar in both the sexes, indicating almost identical metabolic activity. Gonadal development and high feeding intensity are the factors which influenced the condition factor. The seasonal fluctuations in the relative condition factor of both the sexes could be attributed to the sexual cycle, food intake and environmental factors. From the present study, it can be inferred that the variation in the condition of Atropus atropos was due to feeding activity and gonadal maturity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atropus%20atropos" title="Atropus atropos">Atropus atropos</a>, <a href="https://publications.waset.org/abstracts/search?q=length-weight%20relationship" title=" length-weight relationship"> length-weight relationship</a>, <a href="https://publications.waset.org/abstracts/search?q=Mangalore%20coast" title=" Mangalore coast"> Mangalore coast</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20condition%20factor" title=" relative condition factor"> relative condition factor</a>, <a href="https://publications.waset.org/abstracts/search?q=Kn" title=" Kn"> Kn</a> </p> <a href="https://publications.waset.org/abstracts/68160/length-weight-relationship-and-relative-condition-factor-of-atropus-atropos-bloch-and-schneider-1801-from-mangalore-coast-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68160.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">344</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5239</span> Probabilistic Analysis of Bearing Capacity of Isolated Footing using Monte Carlo Simulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sameer%20Jung%20Karki">Sameer Jung Karki</a>, <a href="https://publications.waset.org/abstracts/search?q=Gokhan%20Saygili"> Gokhan Saygili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The allowable bearing capacity of foundation systems is determined by applying a factor of safety to the ultimate bearing capacity. Conventional ultimate bearing capacity calculations routines are based on deterministic input parameters where the nonuniformity and inhomogeneity of soil and site properties are not accounted for. Hence, the laws of mathematics like probability calculus and statistical analysis cannot be directly applied to foundation engineering. It’s assumed that the Factor of Safety, typically as high as 3.0, incorporates the uncertainty of the input parameters. This factor of safety is estimated based on subjective judgement rather than objective facts. It is an ambiguous term. Hence, a probabilistic analysis of the bearing capacity of an isolated footing on a clayey soil is carried out by using the Monte Carlo Simulation method. This simulated model was compared with the traditional discrete model. It was found out that the bearing capacity of soil was found higher for the simulated model compared with the discrete model. This was verified by doing the sensitivity analysis. As the number of simulations was increased, there was a significant % increase of the bearing capacity compared with discrete bearing capacity. The bearing capacity values obtained by simulation was found to follow a normal distribution. While using the traditional value of Factor of safety 3, the allowable bearing capacity had lower probability (0.03717) of occurring in the field compared to a higher probability (0.15866), while using the simulation derived factor of safety of 1.5. This means the traditional factor of safety is giving us bearing capacity that is less likely occurring/available in the field. This shows the subjective nature of factor of safety, and hence probability method is suggested to address the variability of the input parameters in bearing capacity equations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bearing%20capacity" title="bearing capacity">bearing capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=factor%20of%20safety" title=" factor of safety"> factor of safety</a>, <a href="https://publications.waset.org/abstracts/search?q=isolated%20footing" title=" isolated footing"> isolated footing</a>, <a href="https://publications.waset.org/abstracts/search?q=montecarlo%20simulation" title=" montecarlo simulation"> montecarlo simulation</a> </p> <a href="https://publications.waset.org/abstracts/143681/probabilistic-analysis-of-bearing-capacity-of-isolated-footing-using-monte-carlo-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143681.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">187</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">5238</span> Unraveling the Evolution of Mycoplasma Hominis Through Its Genome Sequence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boutheina%20Ben%20Abdelmoumen%20Mardassi">Boutheina Ben Abdelmoumen Mardassi</a>, <a href="https://publications.waset.org/abstracts/search?q=Salim%20Chibani"> Salim Chibani</a>, <a href="https://publications.waset.org/abstracts/search?q=Safa%20Boujemaa"> Safa Boujemaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Amaury%20Vaysse"> Amaury Vaysse</a>, <a href="https://publications.waset.org/abstracts/search?q=Julien%20Guglielmini"> Julien Guglielmini</a>, <a href="https://publications.waset.org/abstracts/search?q=Elhem%20Yacoub"> Elhem Yacoub</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and aim: Mycoplasma hominis (MH) is a pathogenic bacterium belonging to the Mollicutes class. It causes a wide range of gynecological infections and infertility among adults. Recently, we have explored for the first time the phylodistribution of Tunisian M. hominis clinical strains using an expanded MLST. We have demonstrated their distinction into two pure lineages, which each corresponding to a specific pathotype: genital infections and infertility. The aim of this project is to gain further insight into the evolutionary dynamics and the specific genetic factors that distinguish MH pathotypes Methods: Whole genome sequencing of Mycoplasma hominis clinical strains was performed using illumina Miseq. Denovo assembly was performed using a publicly available in-house pipeline. We used prokka to annotate the genomes, panaroo to generate the gene presence matrix and Jolytree to establish the phylogenetic tree. We used treeWAS to identify genetic loci associated with the pathothype of interest from the presence matrix and phylogenetic tree. Results: Our results revealed a clear categorization of the 62 MH clinical strains into two distinct genetic lineages, with each corresponding to a specific pathotype.; gynecological infections and infertility[AV1] . Genome annotation showed that GC content is ranging between 26 and 27%, which is a known characteristic of Mycoplasma genome. Housekeeping genes belonging to the core genome are highly conserved among our strains. TreeWas identified 4 virulence genes associated with the pathotype gynecological infection. encoding for asparagine--tRNA ligase, restriction endonuclease subunit S, Eco47II restriction endonuclease, and transcription regulator XRE (involved in tolerance to oxidative stress). Five genes have been identified that have a statistical association with infertility, tow lipoprotein, one hypothetical protein, a glycosyl transferase involved in capsule synthesis, and pyruvate kinase involved in biofilm formation. All strains harbored an efflux pomp that belongs to the family of multidrug resistance ABC transporter, which confers resistance to a wide range of antibiotics. Indeed many adhesion factors and lipoproteins (p120, p120', p60, p80, Vaa) have been checked and confirmed in our strains with a relatively 99 % to 96 % conserved domain and hypervariable domain that represent 1 to 4 % of the reference sequence extracted from gene bank. Conclusion: In summary, this study led to the identification of specific genetic loci associated with distinct pathotypes in M hominis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mycoplasma%20hominis" title="mycoplasma hominis">mycoplasma hominis</a>, <a href="https://publications.waset.org/abstracts/search?q=infertility" title=" infertility"> infertility</a>, <a href="https://publications.waset.org/abstracts/search?q=gynecological%20infections" title=" gynecological infections"> gynecological infections</a>, <a href="https://publications.waset.org/abstracts/search?q=virulence%20genes" title=" virulence genes"> virulence genes</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotic%20resistance" title=" antibiotic resistance"> antibiotic resistance</a> </p> <a href="https://publications.waset.org/abstracts/167070/unraveling-the-evolution-of-mycoplasma-hominis-through-its-genome-sequence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167070.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">97</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5237</span> Growth Pattern, Condition Factor and Relative Condition Factor of Twenty Important Demersal Marine Fish Species in Nigerian Coastal Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omogoriola%20Hannah%20Omoloye">Omogoriola Hannah Omoloye</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fish is a key ingredient on the global menu, a vital factor in the global environment and an important basis for livelihood worldwide1. The length – weight relationships (LWRs) is of great importance in fishery assessment2,3. Its importance is pronounced in estimated the average weight at a given length group4 and in assessing the relative well being of a fish population5. Length and weight measurement in conjunction with age data can give information on the stock composition, age at maturity, life span, mortality, growth and production4,5,6,7. In addition, the data on length and weight can also provides important clues to climatic and environmental changes and the change in human consumption practices8,9. However, the size attained by the individual fish may also vary because of variation in food supply, and these in turn may reflect variation in climatic parameters and in the supply of nutrient or in the degree of competition for food. Environment deterioration, for example, may reduce growth rates and will cause a decrease in the average age of the fish. The condition factor and the relative condition factor10 are the quantitative parameters of the well being state of the fish and reflect recent feeding condition of the fish. It is based on the hypothesis that heavier fish of a given length are in better condition11. This factor varies according to influences of physiological factors, fluctuating according to different stages of the development. Condition factor has been used as an index of growth and feeding intensity12. Condition factor decrease with increase in length 12,13 and also influences the reproductive cycle in fish14. The objective here is to determine the length-weight relationships and condition factor for direct use in fishery assessment and for future comparisons between populations of the same species at different locations. To provide quantitative information on the biology of marine fish species trawl from Nigeria coastal water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=condition%20factor" title="condition factor">condition factor</a>, <a href="https://publications.waset.org/abstracts/search?q=growth%20pattern" title=" growth pattern"> growth pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20fish%20species" title=" marine fish species"> marine fish species</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigerian%20Coastal%20water" title=" Nigerian Coastal water"> Nigerian Coastal water</a> </p> <a href="https://publications.waset.org/abstracts/28437/growth-pattern-condition-factor-and-relative-condition-factor-of-twenty-important-demersal-marine-fish-species-in-nigerian-coastal-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28437.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">416</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">5236</span> Effect of Media Osmolarity on Vi Biosynthesis on Salmonella enterica serovar Typhi Strain C6524 Cultured on Batch System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dwi%20Arisandi%20Wijaya">Dwi Arisandi Wijaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Ernawati%20Arifin%20Giri-Rachman"> Ernawati Arifin Giri-Rachman</a>, <a href="https://publications.waset.org/abstracts/search?q=Neni%20Nurainy"> Neni Nurainy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Typhoid fever disease can be prevented by using a polysaccharide-based vaccine Vi which is a virulence factor of S.typhi. To produce high yield Vi polysaccharide from bacteria, it is important to know the biosynthesis of Vi polysaccharide and the regulators involved. In the In vivo condition, S. typhi faces different osmolarity, and the bacterial two-component system OmpR-EnvZ, regulate by up and down Capsular Vi polysaccharide biosynthesis. A high yielded Vi Polysaccharide strain, S. typhi strain C6524 used to study the effect of media osmolarity on Vi polysaccharide biosynthesis and the osmoregulation pattern of S. typhi strain C6524. The methods were performed by grown S. typhi strain C6524 grown on medium with 50 mM, 100 mM, and 150 mM osmolarity with the batch system. Vi polysaccharide concentration was measured by ELISA method. For further investigation of the osmoregulation pattern of strain C6524, the osmoregulator gene, OmpR, has been isolated and sequenced using the specific primer of the OmpR gene. Nucleotide sequence analysis is done with BLAST and Lallign. Amino Acid sequence analysis is done with Prosite and Multiple Sequence Alignment. The results of cultivation showed the average content of polysaccharide Vi for 50 mM, 100 mM, and 150 mM osmolarities 11.49 μg/mL, 12.06 μg/mL, and 14.53 μg/mL respectively. Analysis using Anova stated that the osmolarity treatment of 150 mM significantly affects Vi content. Analysis of nucleotide sequences shows 100% identity between S. typhi strain C6524 and Ty2. Analysis of amino acid sequences shows that the OmpR response regulator protein of the C6524 strain also has a α4-β5-α5 motif which is important for the regulatory activation system when phosphorylation occurs by domain kinase. This indicates that the regulator osmolarity response of S. typhi strain C6524 has no difference with the response regulator owned by S. typhi strain Ty2. A high Vi response rate in the 150 mM osmolarity treatment requires further research for RcsB-RcsC, another two-component system involved in Vi Biosynthesis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=osmoregulator" title="osmoregulator">osmoregulator</a>, <a href="https://publications.waset.org/abstracts/search?q=OmpR" title=" OmpR"> OmpR</a>, <a href="https://publications.waset.org/abstracts/search?q=Salmonella" title=" Salmonella"> Salmonella</a>, <a href="https://publications.waset.org/abstracts/search?q=Vi%20polysaccharide" title=" Vi polysaccharide"> Vi polysaccharide</a> </p> <a href="https://publications.waset.org/abstracts/91048/effect-of-media-osmolarity-on-vi-biosynthesis-on-salmonella-enterica-serovar-typhi-strain-c6524-cultured-on-batch-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91048.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">198</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">5235</span> Adolescent Obesity Leading to Adulthood Cardiovascular Diseases among Punjabi Population</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manpreet%20Kaur">Manpreet Kaur</a>, <a href="https://publications.waset.org/abstracts/search?q=Badaruddoza"> Badaruddoza</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandeep%20Kaur%20Brar"> Sandeep Kaur Brar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increasing prevalence of adolescent obesity is one of the major causes to be hypertensive in adulthood. Various statistical methods have been applied to examine the performance of anthropometric indices for the identification of adverse cardiovascular risk profile. The present work was undertaken to determine the significant traditional risk factors through principal component factor analysis (PCFA) among population based Punjabi adolescents aged 10-18 years. Data was collected among adolescent children from different schools situated in urban areas of Punjab, India. Principal component factor analysis (PCFA) was applied to extract orthogonal components from anthropometric and physiometric variables. Association between components were explained by factor loadings. The PCFA extracted four factors, which explained 84.21%, 84.06% and 83.15% of the total variance of the 14 original quantitative traits among boys, girls and combined subjects respectively. Factor 1 has high loading of the traits that reflect adiposity such as waist circumference, BMI and skinfolds among both sexes. However, waist circumference and body mass index are the indicator of abdominal obesity which increases the risk of cardiovascular diseases. The loadings of these two traits have found maximum in girls adolescents (WC=0.924; BMI=0.905). Therefore, factor 1 is the strong indicator of atherosclerosis in adolescents. Factor 2 is predominantly loaded with blood pressures and related traits (SBP, DBP, MBP and pulse rate) which reflect the risk of essential hypertension in adolescent girls and combined subjects, whereas, factor 2 loaded with obesity related traits in boys (weight and hip circumferences). Comparably, factor 3 is loaded with blood pressures in boys and with height and WHR in girls, while factor 4 contains high loading of pulse pressure among boys, girls and combined group of adolescents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adolescent%20obesity" title="adolescent obesity">adolescent obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=cvd" title=" cvd"> cvd</a>, <a href="https://publications.waset.org/abstracts/search?q=hypertension" title=" hypertension"> hypertension</a>, <a href="https://publications.waset.org/abstracts/search?q=punjabi%20population" title=" punjabi population"> punjabi population</a> </p> <a href="https://publications.waset.org/abstracts/30441/adolescent-obesity-leading-to-adulthood-cardiovascular-diseases-among-punjabi-population" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30441.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">371</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">5234</span> The Development of Potential in Skilled Laborers in Producing Basketry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chutikarn%20Sriwiboon">Chutikarn Sriwiboon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purposes of this paper were to study the production problems of basketry in the central region and to study the development of potential in skilled labourers in producing basketry in three provinces: Suphanburi, Ayuthaya, and Aungthong.

Women attended Hasanuddin University Teaching Hospital and its networking in Makassar, Indonesia was surveyed between February to April 2015 about their obstetrical and gynecological history. Aims: To establish obstetrical risk factor of anal incontinence among women in Makassar. Methods: In a cross sectional face to face interview study, 135 women aged 30 years or more were selected randomly. Participants were asked to complete an anal incontinence questionnaire. Results: From a total sample of 135 respondents, 42,2 % reported has flatulence incontinence. Parity, history of anal sphincter laceration, history of having large baby, history of assisted vaginal delivery were shown have no significant association with anal incontinence, while history of episiotomy was shown have a significant association with anal incontinence (p value < 0.05). The risk of flatulence incontinence was higher among women with history of episiotomy (OR : 2,85, 95 % CI = 1,58- 5,13) Conclusions: This study has confirmed that fecal incontinence is a fairly common symptom. Flatulence incontinence is the most frequent even. An obstetrical factor like episiotomy is one of risk factor that could be avoided in order to prevent anal incontinence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anal%20incontinence" title="anal incontinence">anal incontinence</a>, <a href="https://publications.waset.org/abstracts/search?q=flatulence%20incontinence" title=" flatulence incontinence"> flatulence incontinence</a>, <a href="https://publications.waset.org/abstracts/search?q=obstetrical%20risk%20factor" title=" obstetrical risk factor"> obstetrical risk factor</a>, <a href="https://publications.waset.org/abstracts/search?q=women" title=" women"> women</a> </p> <a href="https://publications.waset.org/abstracts/32498/risk-factor-of-anal-incontinence-among-women-in-makassar" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32498.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">318</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">5231</span> Screen Method of Distributed Cooperative Navigation Factors for Unmanned Aerial Vehicle Swarm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Can%20Zhang">Can Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Qun%20Li"> Qun Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Yonglin%20Lei"> Yonglin Lei</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhi%20Zhu"> Zhi Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong%20Guo"> Dong Guo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aiming at the problem of factor screen in distributed collaborative navigation of dense UAV swarm, an efficient distributed collaborative navigation factor screen method is proposed. The method considered the balance between computing load and positioning accuracy. The proposed algorithm utilized the factor graph model to implement a distributed collaborative navigation algorithm. The GNSS information of the UAV itself and the ranging information between the UAVs are used as the positioning factors. In this distributed scheme, a local factor graph is established for each UAV. The positioning factors of nodes with good geometric position distribution and small variance are selected to participate in the navigation calculation. To demonstrate and verify the proposed methods, the simulation and experiments in different scenarios are performed in this research. Simulation results show that the proposed scheme achieves a good balance between the computing load and positioning accuracy in the distributed cooperative navigation calculation of UAV swarm.

MTX decreased serum testosterone, induced histopathological testicular damage, increased testicular tumor necrosis factor-α level and expression of nuclear factor-κB and cyclooxygenase-2. In MTX/RES group, significant reversal of these parameters was noticed, compared to MTX group. Testicular expression of multidrug resistance protein (Mrp) 3 was three- and five-folds higher in RES- and MTX/RES-treated groups, respectively. In vitro, using prostate cancer cells, each of MTX and RES alone induced cytotoxicity with IC50 0.18 ± 0.08 and 20.5 ± 3.6 µM, respectively. RES also significantly enhanced cytotoxicity of MTX. In conclusion, RES appears to have dual beneficial effect, as it promotes MTX tumor cytotoxicity, while protecting the testes, probably via up-regulation of testicular Mrp3 as a novel mechanism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=resveratrol" title="resveratrol">resveratrol</a>, <a href="https://publications.waset.org/abstracts/search?q=methotrexate" title=" methotrexate"> methotrexate</a>, <a href="https://publications.waset.org/abstracts/search?q=multidrug%20resistance%20protein%203" title=" multidrug resistance protein 3"> multidrug resistance protein 3</a>, <a href="https://publications.waset.org/abstracts/search?q=tumor%20necrosis%20factor-%CE%B1" title=" tumor necrosis factor-α"> tumor necrosis factor-α</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear%20factor-%CE%BAB" title=" nuclear factor-κB"> nuclear factor-κB</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclooxygenase-2" title=" cyclooxygenase-2"> cyclooxygenase-2</a> </p> <a href="https://publications.waset.org/abstracts/17378/involvement-of-multi-drug-resistance-protein-mrp-3-in-resveratrol-protection-against-methotrexate-induced-testicular-damage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17378.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">454</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5229</span> Investigation of Slope Stability in Gravel Soils in Unsaturated State</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyyed%20Abolhasan%20Naeini">Seyyed Abolhasan Naeini</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Azini"> Ehsan Azini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we consider the stability of a slope of 10 meters in silty gravel soils with modeling in the Geostudio Software.  we intend to use the parameters of the volumetric water content and suction dependent permeability and provides relationships and graphs using the parameters obtained from gradation tests and Atterberg’s limits.

Seghir </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The establishment of intravenous catheters in hospitalized patient is an act common in many clinical situations. These therapeutic tools, from their insertion in the body, represent gateways including fungal germs prone. The latter can generate the growth of biofilms, which can be the cause of fungal infection. Faced with this problem, we conducted a study at the University Hospital of Tlemcen in the neurosurgery unit and aims to isolate and identify Candida yeasts from intravenous catheters. Then test their ability to form biofilms. Materials and methods: 256 patient hospitalized in surgery of the hospital in west Algeria were submitted to this study. All samples were taken from peripheral venous catheters implanted for 72 hours or more days. A total of 31 isolates of Candida species were isolated. MIC and SMIC are determined at 80% inhibition by the test XTT tetrazolium measured at 490 nm. The final concentrations of antifungal agent being between 0.03 and 16 mg / ml for amphotericin B and from 0.015 to 8 mg / mL caspofungin. Results: 31 Candida species isolates from catheters including 14 Candida albicans and 17 Candida non albicans . 21 strains of all the isolates were able to form biofilms. In their form of Planktonic cells, all isolates are 100% susceptible to antifungal agents tested. However, in their state of biofilms, more isolates have become tolerant to the tested antifungals. Conclusion: Candida yeasts isolated from intravascular catheters are considered an important virulence factor in the pathogenesis of infections. Their involvement in catheter-related infections can be disastrous for their potential to generate biofilms. They survive high concentrations of antifungal where treatment failure. Pending the development of a therapeutic approach antibiofilm related to catheters, their mastery is going through: -The risk of infection prevention based on the training and awareness of medical staff, -Strict hygiene and maximum asepsis, and -The choice of material limiting microbial colonization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=candida" title="candida">candida</a>, <a href="https://publications.waset.org/abstracts/search?q=biofilm" title=" biofilm"> biofilm</a>, <a href="https://publications.waset.org/abstracts/search?q=hospital" title=" hospital"> hospital</a>, <a href="https://publications.waset.org/abstracts/search?q=infection" title=" infection"> infection</a>, <a href="https://publications.waset.org/abstracts/search?q=amphotericin%20B" title=" amphotericin B"> amphotericin B</a>, <a href="https://publications.waset.org/abstracts/search?q=caspofungin" title=" caspofungin"> caspofungin</a> </p> <a href="https://publications.waset.org/abstracts/31771/pathogenic-candida-biofilms-producers-involved-in-healthcare-associated-infections" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31771.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">323</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">5227</span> Turbulent Flow in Corrugated Pipes with Helical Grooves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Mendes">P.

By using the recombinant factor VIII in these patients, elective orthopedic surgeries have been done approximately in 40 last years. About 10-30 % of these patients have bleeding complications in their surgeries even by using recombinant factor VIII because of their inhibitor against FVIII molecule. Preoperative haemostatic management in these patients is challenging. We treated a 28-year-old male patient with hemophilia A with FVIII inhibitor which had been detected when he was14 years old (with the titer 54 Bethesda unit(BU)) scheduled for total knee arthroplasty (TKA). We use 90 µg/kg rFVIIa just before the surgery and every 2 hours during surgery. The patient did not have any significant hemorrhage during the surgery and after that. For the 2 days after surgery, the rFVIIa repeated every 2 hours as the same as preoperative dosage(90 µg/kg) and for another 2 days of postoperative admission it continued every 4 hours. After 4th day, the rFVIIa continued every 6 hours with the same dosage until the sixth day from the surgery, and finally the patient were discharged about two weeks after surgery. Seven days after the discharge, he came back for the follow up visit. On the follow up examination, the site of the surgery had neither infection hemarthroses signs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hemophilia" title="hemophilia">hemophilia</a>, <a href="https://publications.waset.org/abstracts/search?q=factor%20VIII%20inhibitor" title=" factor VIII inhibitor"> factor VIII inhibitor</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20knee%20replacement" title=" total knee replacement"> total knee replacement</a>, <a href="https://publications.waset.org/abstracts/search?q=rFVIIa" title=" rFVIIa"> rFVIIa</a> </p> <a href="https://publications.waset.org/abstracts/37428/total-knee-arthroplasty-in-a-haemophilia-a-patient-with-high-titre-of-inhibitor-using-recombinant-factor-viia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37428.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">440</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">5223</span> A Study of the Relationship between Time Management Behaviour and Job Satisfaction of Higher Education Institutes in India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sania%20K.%20Rao">Sania K.

Auxiliary switch turns on and off with zero current switching (ZCS). Also, the main diode turns on with zero voltage switching (ZVS) and turns off with ZCS. The proposed converter has features like low cost, simple control and structure. The output current and voltage are controlled by the proposed PFC converter in wide line and load range. The theoretical analysis of converter is clarified and the operating steps are given in detail. The simulation results of converter are obtained for 500 W and 100 kHz. It is observed that the semiconductor devices operate with soft switching (SS) perfectly. So, the switching power losses are minimum.

The study will be based on the companies that form part of the Nifty Fifty Index for a period of five years: 2011 to 2016. The asset pricing model is examined by forming portfolios on the basis of three variables – market capitalization (size effect), book-to-market equity ratio (value effect) and profitability. The study provides a basis to test the presence of the Fama-French Four factor model in Indian stock market. This study may provide a basis for future research in the generalized asset pricing model comprising of multiple risk factors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=book%20to%20market%20equity" title="book to market equity">book to market equity</a>, <a href="https://publications.waset.org/abstracts/search?q=Fama%20French%20four%20factor%20model" title=" Fama French four factor model"> Fama French four factor model</a>, <a href="https://publications.waset.org/abstracts/search?q=market%20capitalization" title=" market capitalization"> market capitalization</a>, <a href="https://publications.waset.org/abstracts/search?q=profitability" title=" profitability"> profitability</a>, <a href="https://publications.waset.org/abstracts/search?q=size%20effect" title=" size effect"> size effect</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20effect" title=" value effect"> value effect</a> </p> <a href="https://publications.waset.org/abstracts/76959/fama-french-four-factor-model-a-study-of-nifty-fifty-companies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76959.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">263</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">5218</span> Combined Fuzzy and Predictive Controller for Unity Power Factor Converter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelhalim%20Kessal">Abdelhalim Kessal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper treats a design of combined control of a single phase power factor correction (PFC). The strategy of the proposed control is based on two parts, the first, for the outer loop (DC output regulated voltage), and the second govern the input current of the converter in order to achieve a sinusoidal form in phase with the grid voltage. Two kinds of regulators are used, Fuzzy controller for the outer loop and predictive controller for the inner loop. The controllers are verified and discussed through simulation under MATLAB/Simulink platform. Also an experimental confirmation is applied.

The systems with 16 channels have been simulated for evaluation of various parameters; Bit Error Rate, Quality Factor, for threshold values for a range of wavelength from 1471 nm to 1611 nm. Comparison of various combination of configurations have been analyzed with EDFA and FRA but EDFA-FRA configuration performance has been found satisfactory in terms of performance indices and stable region. The paper also compared various parameters quantized with different configurations individually. It has been found that Q factor has high value with less value of BER and high resolution for EDFA-FRA configuration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EDFA" title="EDFA">EDFA</a>, <a href="https://publications.waset.org/abstracts/search?q=FRA" title=" FRA"> FRA</a>, <a href="https://publications.waset.org/abstracts/search?q=WDM" title=" WDM"> WDM</a>, <a href="https://publications.waset.org/abstracts/search?q=Q%20factor" title=" Q factor"> Q factor</a>, <a href="https://publications.waset.org/abstracts/search?q=BER" title=" BER"> BER</a> </p> <a href="https://publications.waset.org/abstracts/70088/impact-of-hybrid-optical-amplifiers-on-16-channel-wavelength-division-multiplexed-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70088.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">354</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">5216</span> Evaluation of Longitudinal and Hoop Stresses and a Critical Study of Factor of Safety (FoS) in Design of a Glass-Fiber Pressure Vessel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zainul%20Huda">Zainul Huda</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Hani%20Ajani">Mohammed Hani Ajani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The design, manufacture, and operation of thin-walled pressure vessels must be based on maximum safe operating pressure and an adequate factor of safety (FoS). This research paper first reports experimental evaluation of longitudinal and hoops stresses based on working pressure as well as maximum pressure; and then includes a critical study of factor of safety (FoS) in the design of a glass fiber pressure vessel. Experimental work involved the use of measuring instruments and the readings from pressure gauges. Design calculations involved the computations of design stress and FoS; the latter was based on breaking strength of 55 MPa for the glass fiber (pressure-vessel material). The experimentally determined FoS value has been critically compared with the general FoS allowed in the design of glass fiber pressure vessels. <p class="card-text"><strong>Keywords:</strong> <a
