In this paper various aspect of practical application of SFRA has been studied. Open circuit and short circuit measurement were done on different phases of high voltage and low voltage winding. A case study was presented for the transformer of rating 31.5 MVA for various frequency ranges. A clear picture was presented for sub- frequency ranges for HV as well as LV winding. The main motive of work is to investigate high voltage short circuit response. The theoretical concept about SFRA responses is validated with expert system software results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transformer%20winding" title="transformer winding">transformer winding</a>, <a href="https://publications.waset.org/abstracts/search?q=SFRA" title=" SFRA"> SFRA</a>, <a href="https://publications.waset.org/abstracts/search?q=OCT%20%26%20SCT" title=" OCT & SCT"> OCT & SCT</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency%20deviation" title=" frequency deviation"> frequency deviation</a> </p> <a href="https://publications.waset.org/abstracts/27973/field-experience-with-sweep-frequency-response-analysis-for-power-transformer-diagnosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27973.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">957</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">1745</span> ChaQra: A Cellular Unit of the Indian Quantum Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shashank%20Gupta">Shashank Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Iteash%20Agarwal"> Iteash Agarwal</a>, <a href="https://publications.waset.org/abstracts/search?q=Vijayalaxmi%20Mogiligidda"> Vijayalaxmi Mogiligidda</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Kumar%20Krishnan"> Rajesh Kumar Krishnan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sruthi%20Chennuri"> Sruthi Chennuri</a>, <a href="https://publications.waset.org/abstracts/search?q=Deepika%20Aggarwal"> Deepika Aggarwal</a>, <a href="https://publications.waset.org/abstracts/search?q=Anwesha%20Hoodati"> Anwesha Hoodati</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheroy%20Cooper"> Sheroy Cooper</a>, <a href="https://publications.waset.org/abstracts/search?q=Ranjan"> Ranjan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Bilal%20Sheik"> Mohammad Bilal Sheik</a>, <a href="https://publications.waset.org/abstracts/search?q=Bhavya%20K.%20M."> Bhavya K.

It is great to push the boundaries on these fronts, but these isolated approaches are neither scalable nor cost-effective due to the requirements of specialised hardware and different infrastructure. Current and future QKD network requires addressing different sets of challenges apart from distance, key rate, and quantum security. In this regard, we present ChaQra -a sub-quantum network with core features as 1) Crypto agility (integration in the already deployed telecommunication fibres), 2) Software defined networking (SDN paradigm for routing different nodes), 3) reliability (addressing denial-of-service with hybrid quantum safe cryptography), 4) upgradability (modules upgradation based on scientific and technological advancements), 5) Beyond QKD (using QKD network for distributed computing, multi-party computation etc). Our results demonstrate a clear path to create and accelerate quantum secure Indian subcontinent under the national quantum mission. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quantum%20network" title="quantum network">quantum network</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20key%20distribution" title=" quantum key distribution"> quantum key distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20security" title=" quantum security"> quantum security</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20information" title=" quantum information"> quantum information</a> </p> <a href="https://publications.waset.org/abstracts/186156/chaqra-a-cellular-unit-of-the-indian-quantum-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186156.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">56</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">1744</span> Multi Cloud Storage Systems for Resource Constrained Mobile Devices: Comparison and Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajeev%20Kumar%20Bedi">Rajeev Kumar Bedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaswinder%20Singh"> Jaswinder Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunil%20Kumar%20Gupta"> Sunil Kumar Gupta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cloud storage is a model of online data storage where data is stored in virtualized pool of servers hosted by third parties (CSPs) and located in different geographical locations. Cloud storage revolutionized the way how users access their data online anywhere, anytime and using any device as a tablet, mobile, laptop, etc. A lot of issues as vendor lock-in, frequent service outage, data loss and performance related issues exist in single cloud storage systems. So to evade these issues, the concept of multi cloud storage introduced. There are a lot of multi cloud storage systems exists in the market for mobile devices. In this article, we are providing comparison of four multi cloud storage systems for mobile devices Otixo, Unclouded, Cloud Fuze, and Clouds and evaluate their performance on the basis of CPU usage, battery consumption, time consumption and data usage parameters on three mobile phones Nexus 5, Moto G and Nexus 7 tablet and using Wi-Fi network.

Influenza A Virus (IAV) surface protein hemagglutinin is known to play an important role in viral attachment to the host sialic acid receptors and concentrate in lipid rafts for efficient viral fusion. Selective nature of Influenza A virus to utilize rafts micro-domain for efficient virus assembly and budding has been explored in depth. However, the detailed mechanism of IAV binding to host cell membrane and entry into the host remains elusive. In the present study we investigated the role of lipid rafts in early life cycle events of IAV. Role of host lipid rafts was studied using raft disruption method by extraction of cholesterol by Methyl-β-Cyclodextrin. Using GM1, a well-known lipid raft marker, we were able to observe co-localization of IAV on lipid rafts on the host cell membrane. This experiment suggests a direct involvement of lipid rafts in the initiation of the IAV life cycle. Upon disruption of lipid rafts by Methyl-b-cyclodextrin, we observed a significant reduction in IAV binding on the host cell surface indicating a significant decrease in virus attachment to coherent membrane rafts. Our results provide proof that host lipid rafts and their constituents play an important role in the adsorption of IAV. This study opens a new avenues in IAV virus-host interactions to combat infection at a very early steps of the viral lifecycle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lipid%20raft" title="lipid raft">lipid raft</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption"> adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=cholesterol" title=" cholesterol"> cholesterol</a>, <a href="https://publications.waset.org/abstracts/search?q=methyl-%CE%B2-cyclodextrin" title=" methyl-β-cyclodextrin"> methyl-β-cyclodextrin</a>, <a href="https://publications.waset.org/abstracts/search?q=GM1" title=" GM1"> GM1</a> </p> <a href="https://publications.waset.org/abstracts/43068/critical-role-of-lipid-rafts-in-influenza-a-virus-binding-to-host-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43068.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">365</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">1741</span> Graphical User Interface Testing by Using Deep Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akshat%20Mathur">Akshat Mathur</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunil%20Kumar%20Khatri"> Sunil Kumar Khatri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents brief about how the use of Artificial intelligence in respect to GUI testing can reduce workload by using DL-fueled method.

Their appeal lies in a long cycle life, high power density, and rapid recharge capabilities. These exceptional traits attract researchers aiming to develop advanced, cost-effective, and high-energy-density electrode materials for next-generation energy storage solutions. Two-dimensional (2D) nanostructures are highly attractive for fabricating nanodevices due to their high surface-to-volume ratio and good compatibility with device design. In the current study, a composite was synthesized by combining MoS2 with reduced graphene oxide (rGO) under optimal conditions and characterized using various techniques, including XRD, FTIR, SEM and XPS. The electrochemical properties of the composite material were assessed through cyclic voltammetry, galvanostatic charging-discharging and electrochemical impedance spectroscopy. The supercapacitor device demonstrated a specific capacitance of 153 F g-1 at a current density of 1 Ag-1, achieving an excellent energy density of 30.5 Wh kg-1 and a power density of 600 W kg-1. Additionally, it maintained excellent cyclic stability over 5000 cycles, establishing it as a promising candidate for efficient and durable energy storage solutions. These findings highlight the dynamic relationship between electrode materials and offer valuable insights for the development and enhancement of high-performance symmetric devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=2D%20material" title="2D material">2D material</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20density" title=" energy density"> energy density</a>, <a href="https://publications.waset.org/abstracts/search?q=galvanostatic%20charge-discharge" title=" galvanostatic charge-discharge"> galvanostatic charge-discharge</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrothermal%20reactor" title=" hydrothermal reactor"> hydrothermal reactor</a>, <a href="https://publications.waset.org/abstracts/search?q=specific%20capacitance" title=" specific capacitance"> specific capacitance</a> </p> <a href="https://publications.waset.org/abstracts/193469/fabrication-of-2d-nanostructured-hybrid-material-based-devices-for-high-performance-supercapacitor-energy-storage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193469.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">14</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">1739</span> Antidiabetic Effect of Methanolic Leaves Extract and Isolated Constituents from Saraca Asoca</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunil%20Kumar">Sunil Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: The present study was performed to investigate the antidiabetic effect of the constituents isolated from Sarca asoca by enzyme inhibitory activity.

Heat transfer effects in this 1D dimensional slab convective and the radiative boundary conditions are also considered.

The search for naturally occurring lead compounds has continued in recent years as well, with the constituents of marine flora and fauna along with those of telluric microorganisms and plants being investigated for their anti-bacterial and anti-cancer activities. It has been observed that such promising lead molecules incline to promptly generate substantial attention among scientists like synthetic organic chemists and biologists. Subsequently, the availability of a given precious natural product sample may be enriched, and it may be possible to determine a preliminary idea of structure-activity relationships to develop synthetic analogues. For instance, anti-tumor drug topotecan is a synthetic chemical compound similar in chemical structure to camptothecin which is found in extracts of Camptotheca acuminate.

The soil-slurry samples were analyzed by capillary GC-NPD methods followed by ultrasound-assisted extraction (UAE) technique and cleanup process. An excellent linear relationship between peak area and concentration obtained in the range 1 to 50 μgkg-1. The detection (S/N, 3 ± 0.5) and quantification (S/N, 7.5 ± 2.5) limits were 3 and 10 μgkg-1 respectively. Well spiked recoveries were achieved from 96.28 to 99.33 % at levels 5 and 20 μgkg-1 and method precision (% RSD) was ≤ 5%. The soils dissipation of tebuconazole was fitted in first order kinetic-model with half-life between 34.48 to 48.13 days. The soil organic-carbon (SOC) content correlated well with the dissipation rate constants (DRC) of the fungicide Tebuconazole. An increase in the SOC content resulted in faster dissipation. The results indicate that the soil organic carbon and tebuconazole concentrations plays dominant role in dissipation processes. The initial concentration illustrated that the degradation rate of tebuconazole in soils was concentration dependent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cropland%20soil" title="cropland soil">cropland soil</a>, <a href="https://publications.waset.org/abstracts/search?q=dissipation" title=" dissipation"> dissipation</a>, <a href="https://publications.waset.org/abstracts/search?q=laboratory%20incubation" title=" laboratory incubation"> laboratory incubation</a>, <a href="https://publications.waset.org/abstracts/search?q=tebuconazole" title=" tebuconazole"> tebuconazole</a> </p> <a href="https://publications.waset.org/abstracts/51929/dissipation-of-tebuconazole-in-cropland-soils-as-affected-by-soil-factors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51929.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">253</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">1735</span> Hydro-Gravimetric Ann Model for Prediction of Groundwater Level</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jayanta%20Kumar%20Ghosh">Jayanta Kumar Ghosh</a>, <a href="https://publications.waset.org/abstracts/search?q=Swastik%20Sunil%20Goriwale"> Swastik Sunil Goriwale</a>, <a href="https://publications.waset.org/abstracts/search?q=Himangshu%20Sarkar"> Himangshu Sarkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Groundwater is one of the most valuable natural resources that society consumes for its domestic, industrial, and agricultural water supply. Its bulk and indiscriminate consumption affects the groundwater resource. Often, it has been found that the groundwater recharge rate is much lower than its demand. Thus, to maintain water and food security, it is necessary to monitor and management of groundwater storage. However, it is challenging to estimate groundwater storage (GWS) by making use of existing hydrological models. To overcome the difficulties, machine learning (ML) models are being introduced for the evaluation of groundwater level (GWL). Thus, the objective of this research work is to develop an ML-based model for the prediction of GWL. This objective has been realized through the development of an artificial neural network (ANN) model based on hydro-gravimetry. The model has been developed using training samples from field observations spread over 8 months. The developed model has been tested for the prediction of GWL in an observation well. The root means square error (RMSE) for the test samples has been found to be 0.390 meters. Thus, it can be concluded that the hydro-gravimetric-based ANN model can be used for the prediction of GWL. However, to improve the accuracy, more hydro-gravimetric parameter/s may be considered and tested in future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title="machine learning">machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=hydro-gravimetry" title=" hydro-gravimetry"> hydro-gravimetry</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20water%20level" title=" ground water level"> ground water level</a>, <a href="https://publications.waset.org/abstracts/search?q=predictive%20model" title=" predictive model"> predictive model</a> </p> <a href="https://publications.waset.org/abstracts/156817/hydro-gravimetric-ann-model-for-prediction-of-groundwater-level" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156817.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">1734</span> Synthesis of 2-Aminoisocoumarinoselenazoles via Transition Metal-Free Alkylation and Ru(II)-Catalyzed [4+2] Alkyne Annulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunil%20Kumar">Sunil Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandip%20Dhole"> Sandip Dhole</a>, <a href="https://publications.waset.org/abstracts/search?q=Deepak%20Salunke"> Deepak Salunke</a>, <a href="https://publications.waset.org/abstracts/search?q=Chung-ming%20Sun"> Chung-ming Sun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heterocycles bearing nitrogen, oxygen, and selenium are present in innumerable biologically active compounds. For instance, coumarin containing dicoumarol acts as naturally occurring anticoagulant. 2-Acylamido selenazole works as Store-Operated Calcium (SOC) channel regulator. Therefore, due to biologically significance of selenazole and coumarin and our quest to develop efficient methodologies for the synthesis of complex heterocycles, the trisubstituted angular isocoumarinoselenazole synthesis was proposed and achieved by starting from nitrobenzoic acid derivative, available commercially. Synthetic procedure involves three steps: i) the construction of 2-aminobenzoselenazoles, ii) their regioselective N-alkylation at position-2 and iii) alkyne insertion via Ru catalyzed C-H activation. Transition metal free synthesis of benzoselenazoles was successfully brought about by the addition/elimination reaction via intramolecular C-Se bond formation. In the next step, N-alkylation of selenazole furnished two regioisomers. Both the isomers exhibited different reactivity towards [4+2] alkyne annulation reaction. The fusion of α-pyrone ring on the benzo[1,3-d]selenazole skeleton was achieved via Ru(II)-catalyzed C-H activation and alkyne insertion. As evident from mechanism, the selenazole 'N' plays an important role for the experiential selectivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alkylation" title="alkylation">alkylation</a>, <a href="https://publications.waset.org/abstracts/search?q=alkyne%20insertion" title=" alkyne insertion"> alkyne insertion</a>, <a href="https://publications.waset.org/abstracts/search?q=coumarin" title=" coumarin"> coumarin</a>, <a href="https://publications.waset.org/abstracts/search?q=selenazole" title=" selenazole "> selenazole </a> </p> <a href="https://publications.waset.org/abstracts/125051/synthesis-of-2-aminoisocoumarinoselenazoles-via-transition-metal-free-alkylation-and-ruii-catalyzed-42-alkyne-annulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125051.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">125</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">1733</span> Fractional Order Differentiator Using Chebyshev Polynomials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Koushlendra%20Kumar%20Singh">Koushlendra Kumar Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Manish%20Kumar%20Bajpai"> Manish Kumar Bajpai</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Kumar%20Pandey"> Rajesh Kumar Pandey</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A discrete time fractional orderdifferentiator has been modeled for estimating the fractional order derivatives of contaminated signal.

In this paper, we present a novel design and development of photo electronics based system for reading old and used punched cards and storing its binary information for transforming them into an effective image file format. In our textile industry the jacquard punched cards holes diameters having the sizes of 3mm, 5mm and 5.5mm pitch. Before the adaptation of computing systems in the field of textile industry those punched cards were prepared manually without digital design source, but those punched cards are having rich woven designs. Now, the idea is to retrieve binary information from the jacquard punched cards and store them in digital (Non-Graphics) format before processing it. After processing the digital format (Non-Graphics) it is converted into an effective image file format through either by Row major or Column major parsing technique.To accomplish these activities, an embedded system based device and software integration is developed.

Ensuring tuning of state estimator is a repeated process and cannot be left once a good solution is obtained. This paper attempts to demonstrate methods to improve state estimator solution by identifying incorrect modelling and telemetry inputs to the application. In this work, identification of database topology modelling error by plotting static network using node-to-node connection details is demonstrated with examples. Analytical methods to identify wrong transmission parameters, incorrect limits and mistakes in pseudo load and generator modelling are explained with various cases observed. Further, methods used for active and reactive power tuning using bus summation display, reactive power absorption summary, and transformer tap correction are also described. In a large power system, verifying all network static data and modelling parameter on regular basis is difficult .The proposed tuning methods can be easily used by operators to quickly identify errors to obtain the best possible state estimation performance. This, in turn, can lead to improved decision-support capabilities, ultimately enhancing the safety and reliability of the power grid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20power%20tuning" title="active power tuning">active power tuning</a>, <a href="https://publications.waset.org/abstracts/search?q=database%20modelling" title=" database modelling"> database modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20power" title=" reactive power"> reactive power</a>, <a href="https://publications.waset.org/abstracts/search?q=state%20estimator" title=" state estimator"> state estimator</a> </p> <a href="https://publications.waset.org/abstracts/194306/state-estimator-performance-enhancement-methods-for-identifying-errors-in-modelling-and-telemetry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194306.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">7</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">1729</span> An Experimental Study to Investigate the Behaviour of Torque Fluctuation of Crossflow Turbines Operating in an Open Channel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunil%20Kumar%20Singal">Sunil Kumar Singal</a>, <a href="https://publications.waset.org/abstracts/search?q=Manoj%20Sood"> Manoj Sood</a>, <a href="https://publications.waset.org/abstracts/search?q=Upendra%20Bajpai"> Upendra Bajpai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Instream technology is the upcoming sustainable approach in the hydro sector for energy harnessing. With well-known cross-sections and regulated supply, open channels are the most prominent locations for the installation of hydrokinetic turbines. The fluctuation in generated torque varies with site condition (flow depth and flow velocity), as well as with the type of turbine. The present experimental study aims to investigate the torque/power fluctuations of crossflow hydrokinetic turbines operating at different flow velocities and water depths. The flow velocity is varied from 1.0 m/s to 2.0 m/s. The complete assembly includes an open channel having dimensions of 0.3 m (depth) x 0.71 m (width) x 4.5 m (length), along with a lifting mechanism for varying the channel slope, a digital transducer for monitoring the torque, power, and rpm, a digital handheld water velocity meter for measuring the flow velocity. Further, a time series of torque, power, and rpm is plotted for a duration of 30 minutes showing the continuous operation of the turbine. A comparison of Savonius, Darrieus, and their improved twisted and helical blades is also presented in the study. A correlation has also been developed for assessing the hydropower generation from the installed turbine. The developed correlations will be very useful in the decision-making process for development at a site. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=darrieus%20turbine" title="darrieus turbine">darrieus turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20velocity" title=" flow velocity"> flow velocity</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20channel" title=" open channel"> open channel</a>, <a href="https://publications.waset.org/abstracts/search?q=savoinus%20turbine" title=" savoinus turbine"> savoinus turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20depth" title=" water depth"> water depth</a>, <a href="https://publications.waset.org/abstracts/search?q=hydropower" title=" hydropower"> hydropower</a> </p> <a href="https://publications.waset.org/abstracts/171312/an-experimental-study-to-investigate-the-behaviour-of-torque-fluctuation-of-crossflow-turbines-operating-in-an-open-channel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171312.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">85</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">1728</span> Spatial Pattern of Child Sex Ratio in Haryana 1991-2011</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunil%20Kumar">Sunil Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Kavita%20Saini"> Kavita Saini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Haryana emerged as a state after the separation from Punjab since November, 1966. It had only 7 districts at that time but subsequently their number increased and presents their 21 districts in the state. Age and sex composition occupies very important positions in any discussion on characteristics of a population. Changes in sex ratio largely reflect the underlying socio-economic and cultural patterns of a society in different ways. Child sex ratio in Haryana is continuously decreasing and according to the census child sex ratio found lowest position in the state. Therefore, the aims of this study to examine the spatial- temporal pattern of Child sex ratio during the period 1991-2011 and identify the ‘epicenter’ or core areas of deficit of females in Haryana using tehsil level data during the period 2001-2011. This study is primarily based on the secondary sources and data were collected from the ‘Census of India’ and ‘Statistical Department’ of Haryana. The standard deviation method has been used to see the average value of child sex ratio in the study. The maximum child sex ratio declined is noticed in the district of Mahendergarh, Jhajjar, Rewari and Sonipat. However, the west and south-western part of the state marked with consistently better child sex ratio throughout the period. This is vast contiguous belt running in the north-west to south-east direction from Punjab border to NCT of Delhi and reported a very low child sex ratio. Tehsils which have reported lower child sex ratio than the state average has been called ‘Core Problem Area’ or ‘epicenter’. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=child%20sex%20ratio" title="child sex ratio">child sex ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=core%20areas" title=" core areas"> core areas</a>, <a href="https://publications.waset.org/abstracts/search?q=epicenter" title=" epicenter"> epicenter</a>, <a href="https://publications.waset.org/abstracts/search?q=Haryana" title=" Haryana"> Haryana</a> </p> <a href="https://publications.waset.org/abstracts/21527/spatial-pattern-of-child-sex-ratio-in-haryana-1991-2011" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21527.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">410</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">1727</span> Bioefficacy of Catharanthus roseus on Reproductive Performance of Red Cotton Bug, Dysdercus koenigii (Heteroptera: Pyrrhocoriedae)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunil%20Kayesth">Sunil Kayesth</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamal%20Kumar%20Gupta"> Kamal Kumar Gupta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Influence of hexane extract of Catharanthus roseus leaves on reproductive fitness of Dysdercus koenigii was investigated by evaluating mating behaviour, oviposition behaviour and fertility of the treated insects. The volatiles of the plants were extracted in hexane by ‘cold extraction method’. The insects were treated with the extracts by ‘dry film residual method’. Our studies indicated that the treated male showed altered courtship behaviour, less number of mounting attempts, took more time to mate, less percent successful mating, and more disrupted mating. Similarly, the treated female exhibited either mating refusal or neutral behaviour towards courting males. The maximum disruption in the mating was observed in a cross T♂ X T♀, where males and females were treated with Catharanthus extract. The Dysdercus treated with Catharanthus extracts also showed marked reduction in their reproductive success. The treated females laid lesser number of egg batches and eggs in their life span. Catharanthus extract was effective in alteration of the oviposition behaviour. The eggs laid by the mated females were fertile indicating insemination of the mated females. However, the percent hatchability of the eggs laid by the treated females was less than control. The GC-MS analysis of the extract revealed the presence of juvenile hormone mimics, and the intermediates of juvenile hormone biosynthesis. Therefore, some of these compounds individually or synergistically alter reproductive behaviour of Dysdercus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Catharanthus%20roseus" title="Catharanthus roseus">Catharanthus roseus</a>, <a href="https://publications.waset.org/abstracts/search?q=Dysdercus%20koenigii" title=" Dysdercus koenigii"> Dysdercus koenigii</a>, <a href="https://publications.waset.org/abstracts/search?q=GC-MS%20analysis" title=" GC-MS analysis"> GC-MS analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=reproductive%20performance" title=" reproductive performance"> reproductive performance</a> </p> <a href="https://publications.waset.org/abstracts/69108/bioefficacy-of-catharanthus-roseus-on-reproductive-performance-of-red-cotton-bug-dysdercus-koenigii-heteroptera-pyrrhocoriedae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69108.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">260</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">1726</span> Screening for Antibacterial Activity of Fungi from Indian Marine Environments: A Possible Alternative for New Antibiotics for the Treatment of Skin Microbial Infections</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shivankar%20Agrawal">Shivankar Agrawal</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunil%20Kumar%20Deshmukh"> Sunil Kumar Deshmukh</a>, <a href="https://publications.waset.org/abstracts/search?q=Colin%20Barrow"> Colin Barrow</a>, <a href="https://publications.waset.org/abstracts/search?q=Alok%20Adholeya"> Alok Adholeya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Millions of people worldwide are affected by infectious diseases caused by bacteria and fungi. Skin and skin structure infections (SSSI) represent a significant category of infectious disease. Unexpectedly, many pathogens have developed resistance towards current antibiotics and over the time this problem has become more and more serious. All these new problems necessitate the continuous search for novel and alternative antibiotics and antifungals. The aim of our research is the screening of extracts of marine fungi for their antibacterial activity against bacteria causing skin and wound infection in humans. A total of 40 marine samples were collected from west coast and Andaman Island of India and 35 morphologically different marine fungi were isolated using natural sea water medium. Among 35 marine fungi, eight isolates exhibited significant antimicrobial activity against human pathogens. In the course of systematic screening program for bioactive marine fungi, strain 'D5' was found to be most potent strain with MIC value of 1 mg/mL, which was morphologically identified as Simplicillium lamellicola. The effects of the most active crude extracts against their susceptible test microorganisms were also investigated by SEM analysis. Purification and characterization of crude extracts for identification of active lead molecule is under process. The results of diversity and antimicrobial activity have increased the scope of finding industrially important marine fungi from Indian marine environments and these organisms could be vital sources for the discovery of pharmaceutically useful molecules. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20activity" title="antimicrobial activity">antimicrobial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotic" title=" antibiotic"> antibiotic</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20fungi" title=" marine fungi"> marine fungi</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20infections" title=" skin infections"> skin infections</a> </p> <a href="https://publications.waset.org/abstracts/57470/screening-for-antibacterial-activity-of-fungi-from-indian-marine-environments-a-possible-alternative-for-new-antibiotics-for-the-treatment-of-skin-microbial-infections" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57470.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">265</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">1725</span> Electrochemical Detection of the Chemotherapy Agent Methotrexate in vitro from Physiological Fluids Using Functionalized Carbon Nanotube past Electrodes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shekher%20Kummari">Shekher Kummari</a>, <a href="https://publications.waset.org/abstracts/search?q=V.%20Sunil%20Kumar"> V.

The electrochemical response of the fabricated electrode towards the detection of MTX is examined by cyclic voltammetry (CV), differential pulse voltammetry (DPV) and square wave voltammetry (SWV). CV studies have shown that f-CNTPE electrode system exhibited an excellent electrocatalytic activity towards the oxidation of MTX in phosphate buffer (0.2 M) compared with a conventional carbon paste electrode (CPE). The oxidation peak current is enhanced by nearly two times in magnitude. Applying the DPV method under optimized conditions, a linear calibration plot is achieved over a wide range of concentration from 4.0×10⁻⁷ M to 5.5×10⁻⁶ M with the detection limit 1.6×10⁻⁷ M. further, by applying the SWV method a parabolic calibration plot was achieved starting from a very low concentration of 1.0×10⁻⁸ M, and the sensor could detect as low as 2.9×10⁻⁹ M MTX in 10 s and 10 nM were detected in steady state current-time analysis. The f-CNTPE shows very good selectivity towards the specific recognition of MTX in the presence of important biological interference. The electrochemical biosensor detects MTX in-vitro directly from pharmaceutical sample, undiluted urine and human blood serum samples at a concentration range 5.0×10⁻⁷ M with good recovery limits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amperometry" title="amperometry">amperometry</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20detection" title=" electrochemical detection"> electrochemical detection</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20blood%20serum" title=" human blood serum"> human blood serum</a>, <a href="https://publications.waset.org/abstracts/search?q=methotrexate" title=" methotrexate"> methotrexate</a>, <a href="https://publications.waset.org/abstracts/search?q=MWCNT" title=" MWCNT"> MWCNT</a>, <a href="https://publications.waset.org/abstracts/search?q=SWV" title=" SWV"> SWV</a> </p> <a href="https://publications.waset.org/abstracts/86857/electrochemical-detection-of-the-chemotherapy-agent-methotrexate-in-vitro-from-physiological-fluids-using-functionalized-carbon-nanotube-past-electrodes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86857.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">309</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">1724</span> Autoignition Delay Characterstic of Hydrocarbon (n-Pentane) from Lean to Rich Mixtures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunil%20Verma">Sunil Verma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This report is concerned with study of autoignition delay characterstics of n-pentane.

There are already claimed drugs available in market for treating these problems. However, the challenge remains in finding more potent, environmental friendly, causing minimal side effects and economical cosmeceuticals. This leads to an increased demand for natural cosmeceutical products in the last few decades. Plant derived ingredients are limited because plants either contain toxic metabolites, grow too slow or seasonal harvesting is a problem. The research work carried out in this project aims at isolation, characterization of marine fungal secondary metabolite and evaluating their potential use in future cosmetic skin care products. We have isolated and purified 35 morphologically different fungal isolates from various marine habitats of the India. These isolates have been functionally characterized for anti-tyrosinase, antioxidant and anti-acne activities. For molecular characterization, the Internal Transcribed spacer (ITS) region of 15 functionally active marine fungal isolates was amplified using universal primers, ITS1 and ITS4 and sequenced. Out of 15 marine fungal isolates crude extract of strains D4 (Aspergillus terreus) and P2 (Talaromyces stipitatus) showed 70% and 57% tyrosinase inhibition at 1mg/mL respectively. Strain D5 (Simplicillium lamellicola) has showed significant inhibition against Propionibacterium acnes and Staphylococcus epidermidis. In addition, all these strains also displayed DPPH- radical scavenging activity and may be utilized as skin cosmeceutical applications. Purification and characterization of crude extracts for identification of active lead molecule is under process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-acne" title="anti-acne">anti-acne</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-tyrosinase" title=" anti-tyrosinase"> anti-tyrosinase</a>, <a href="https://publications.waset.org/abstracts/search?q=cosmeceutical" title=" cosmeceutical"> cosmeceutical</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20fungi" title=" marine fungi"> marine fungi</a> </p> <a href="https://publications.waset.org/abstracts/56303/anti-tyrosinase-and-antibacterial-activities-of-marine-fungal-extracts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56303.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">277</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">1722</span> Influence of Catharanthus roseus, Ocimum sanctum and Lantana camara Extracts on Survival and Longevity of Dysdercus koenigii</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunil%20Kayesth">Sunil Kayesth</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamal%20Kumar%20Gupta"> Kamal Kumar Gupta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of resistance among insects and pests, environmental contamination and adverse effects on non-target organisms is contributed by the indiscriminate use of chemical based insecticides. To overcome these environmental and other ecological issues that are need to replace these harmful toxic compounds. The present study was designed to evaluate the effect of Catharanthus roseus, Ocimum sanctum and Lantana camara plants volatiles on survival and longevity of Dysdercus koenigii. The hexane extract and ethanol extracts of these three plants were used. The fifth instars were exposed to hexane extract with concentrations of 10%, 5%, 2.5% 1.25%, 0.1%, 0.5% 0.25%, 0.125% and 0.0625% while, adults were treated with10%, 5%, 2.5% and 1.25%. 1-ml of each of these concentrations was used to make a thin film in sterilized glass jars of 500 ml capacity. Fifteen- newly emerged fifth instar nymphs and adult bugs were treated separately with the extracts for 24- hour exposure to the plant volatiles. For ethanol extracts cottonseed were treated with ethanol extracts of 10%, 5%, 2.5% and 1.25% concentrations. The treated seeds were provided to the Dysdercus for a period of 24 hours and their feeding behaviour was observed. The effect of hexane and ethanol extract of these plants was observed and readings were recorded for 15 days. Survival and longevity of both fifth instars and adults were in correlation with the concentrations of the plant extracts. Among three plant extracts, Ocimum hexane extract was most toxic and Catharanthus was moderate while Lantana was least toxic. The ethanol extracts of Lantana was highly antifeedent while Ocimum was moderate and Catharanthus was least antifeedent. Both Catharanthus and Ocimum appeared to have potential molecules, which possessed insecticidal activity while Ocimum and Lantana showed antifeedent activities. These insecticidal and antifeedent properties may be used in IPM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Catharanthus%20roseus" title="Catharanthus roseus">Catharanthus roseus</a>, <a href="https://publications.waset.org/abstracts/search?q=Ocimum%20sanctum" title=" Ocimum sanctum"> Ocimum sanctum</a>, <a href="https://publications.waset.org/abstracts/search?q=Lantana%20camara" title=" Lantana camara"> Lantana camara</a>, <a href="https://publications.waset.org/abstracts/search?q=Dysdercus%20koenigii" title=" Dysdercus koenigii "> Dysdercus koenigii </a> </p> <a href="https://publications.waset.org/abstracts/39732/influence-of-catharanthus-roseus-ocimum-sanctum-and-lantana-camara-extracts-on-survival-and-longevity-of-dysdercus-koenigii" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39732.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">1721</span> Effects of Seed Culture and Attached Growth System on the Performance of Anammox Hybrid Reactor (AHR) Treating Nitrogenous Wastewater</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Swati%20Tomar">Swati Tomar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunil%20Kumar%20Gupta"> Sunil Kumar Gupta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The start-up of anammox (anaerobic ammonium oxidation) process in hybrid reactor delineated four distinct phases i.e. cell lysis, lag phase, activity elevation and stationary phase. Cell lysis phase was marked by death and decay of heterotrophic denitrifiers resulting in breakdown of organic nitrogen into ammonium. Lag phase showed initiation of anammox activity with turnover of heterotrophic denitrifiers, which is evident from appearance of NO3-N in the effluent. In activity elevation phase, anammox became the dominant reaction, which can be attributed to consequent reduction of NH4-N into N2 with increased NO3-N in the effluent. Proper selection of mixed seed culture at influent NO2-/NH4+ ratio (1:1) and hydraulic retention time (HRT) of 1 day led to early startup of anammox within 70 days. Pseudo steady state removal efficiencies of NH4+ and NO2- were found as 94.3% and 96.4% respectively, at nitrogen loading rate (NLR) of 0.35 kg N/m3d at an HRT of 1 day. Analysis of the data indicated that attached growth system contributes an additional 11% increase in the ammonium removal and results in an average of 29% reduction in sludge washout rate. Mass balance study of nitrogen indicated that 74.1% of total input nitrogen is converted into N2 gas followed by 11.2% being utilized in biomass development. Scanning electron microscope (SEM) observation of the granular sludge clearly showed the presence of cocci and rod shaped microorganisms intermingled on the external surface of the granules. The average size of anammox granules (1.2-1.5 mm) with an average settling velocity of 45.6 m/h indicated a high degree of granulation resulting into formation of well compacted granules in the anammox process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anammox" title="anammox">anammox</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20reactor" title=" hybrid reactor"> hybrid reactor</a>, <a href="https://publications.waset.org/abstracts/search?q=startup" title=" startup"> startup</a>, <a href="https://publications.waset.org/abstracts/search?q=granulation" title=" granulation"> granulation</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrogen%20removal" title=" nitrogen removal"> nitrogen removal</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20seed%20culture" title=" mixed seed culture"> mixed seed culture</a> </p> <a href="https://publications.waset.org/abstracts/45428/effects-of-seed-culture-and-attached-growth-system-on-the-performance-of-anammox-hybrid-reactor-ahr-treating-nitrogenous-wastewater" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45428.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">184</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">1720</span> Clinical and Molecular Characterization of 120 Families with Sporadic Juvenile Onset Open Angle Glaucoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bindu%20I.%20Somarajan">Bindu I.

Studies on a few families of JOAG, that led to the discovery of the Myocilin gene, reported the disease to have an autosomal dominant pattern of inheritance. However, sporadic forms of JOAG been seen to be more common in some populations. Most pathological homozygous mutations in the CYP1B1 gene associated with JOAG have been seen among sporadic cases. Given the higher prevalence of sporadic JOAG cases in our population, we aimed to look for common mutations E229K and R368H, the two most common variants in the CYP1B1 gene associated with glaucoma. Objective: To determine the frequency and evaluate genotype phenotype correlation of CYP1B1 E229K and R368H mutations in a cohort of 120 sporadic Juvenile open angle glaucoma patients.Methods: Unrelated JOAG patients whose first degree relatives had been examined and found to be unaffected were included in the study. The patients and their parents were screened for E229K and R368H mutations. The phenotypic characteristics were compared between probands with and with out these mutations by SPSS v16. Results: Out of 120 JOAG patients included in the study, the E229K mutation was seen in 9 probands (7.5%) and R368H in 7 (5.8%). The average age of onset of the disease (p=0.3) and the highest untreated IOP (p=0.4) among those carrying mutations was not significantly different from those who did not have these mutations. The proportion of probands with angle dysgenesis among those with E229K and R368H mutations was 70% (11 out of 16) in comparison to 65% (67 out of 104) of those who did not harbour these mutations (p=0.56). Similarly the probands with moderate to high myopia among those with E229K and R368H mutations was 20% (3 out of 16) in comparison to 18% (18 out of 104) of those who did not harbour these mutations(p=0.59). Conclusion: The frequency of E229K and R368H mutations of the CYP1B1 gene is low even among sporadic JOAG patients. Moreover there is no clinical correlation between the presence of these mutations and disease severity <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CYP1B1" title="CYP1B1">CYP1B1</a>, <a href="https://publications.waset.org/abstracts/search?q=gene" title=" gene"> gene</a>, <a href="https://publications.waset.org/abstracts/search?q=IOP" title=" IOP"> IOP</a>, <a href="https://publications.waset.org/abstracts/search?q=JOAG" title=" JOAG"> JOAG</a>, <a href="https://publications.waset.org/abstracts/search?q=mutation" title=" mutation"> mutation</a> </p> <a href="https://publications.waset.org/abstracts/77908/clinical-and-molecular-characterization-of-120-families-with-sporadic-juvenile-onset-open-angle-glaucoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77908.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">333</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">1719</span> Investigation of Delivery of Triple Play Service in GE-PON Fiber to the Home Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anurag%20Sharma">Anurag Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Dinesh%20Kumar"> Dinesh Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahul%20Malhotra"> Rahul Malhotra</a>, <a href="https://publications.waset.org/abstracts/search?q=Manoj%20Kumar"> Manoj Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fiber based access networks can deliver performance that can support the increasing demands for high speed connections. One of the new technologies that have emerged in recent years is Passive Optical Networks. This paper is targeted to show the simultaneous delivery of triple play service (data, voice and video). The comparative investigation and suitability of various data rates is presented. It is demonstrated that as we increase the data rate, number of users to be accommodated decreases due to increase in bit error rate. <p class="card-text"><strong>Keywords:</strong> <a
