Controlled Nanoparticle Location for Excellent Microwave Absorption: A Compartmentalized Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a

materials, control in the precise location of nanoparticles is indispensable. It was shown here that ordered arrangement of nanoparticles, possessing different characteristics (electrical/magnetic dipoles), in the blend structure can result in excellent microwave absorption. This is manifested from a high reflection loss of ca. -67 dB for the best blend structure designed here. To attenuate electromagnetic radiations, the key parameters i.e. high electrical conductivity and large dielectric/magnetic loss are targeted here using a conducting inclusion [multiwall carbon nanotubes, MWNTs]; ferroelectric nanostructured material with associated relaxations in the GHz frequency [barium titanate, BT]; and a loss ferromagnetic nanoparticles [nickel ferrite, NF]. In this study, bi-continuous structures were designed using 50/50 (by wt) blends of polycarbonate (PC) and polyvinylidene fluoride (PVDF). The MWNTs was modified using an electron acceptor molecule; a derivative of perylenediimide, which facilitates π-π stacking with the nanotubes and stimulates efficient charge transport in the blends. The nanoscopic materials have specific affinity towards the PVDF phase. Hence, by introducing surface-active groups, ordered arrangement can be tailored. To accomplish this, both BT and NF was first hydroxylated followed by introducing amine-terminal groups on the surface. The latter facilitated in nucleophilic substitution reaction with PC and resulted in their precise location. In this study, we have shown for the first time that by compartmentalized approach, superior EM attenuation can be achieved. For instance, when the nanoparticles were localized exclusively in the PVDF phase or in both the phases, the minimum reflection loss was ca. -18 dB (for MWNT/BT mixture) and -29 dB (for MWNT/NF mixture), and the shielding was primarily through reflection. Interestingly, by adopting the compartmentalized approach where in, the lossy materials were in the PC phase and the conducting inclusion (MWNT) in PVDF, an outstanding reflection loss of ca. -57 dB (for BT and MWNT combination) and -67 dB (for NF and MWNT combination) was noted and the shielding was primarily through absorption. Thus, the approach demonstrates that nanoscopic structuring in the blends can be achieved under macroscopic processing conditions and this strategy can further be explored to design microwave absorbers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=barium%20titanate" title="barium titanate">barium titanate</a>, <a href="https://publications.waset.org/abstracts/search?q=EMI%20shielding" title=" EMI shielding"> EMI shielding</a>, <a href="https://publications.waset.org/abstracts/search?q=MWNTs" title=" MWNTs"> MWNTs</a>, <a href="https://publications.waset.org/abstracts/search?q=nickel%20ferrite" title=" nickel ferrite"> nickel ferrite</a> </p> <a href="https://publications.waset.org/abstracts/36169/immiscible-polymer-blends-with-controlled-nanoparticle-location-for-excellent-microwave-absorption-a-compartmentalized-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36169.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">447</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Cyclostationary Analysis of Polytime Coded Signals for LPI Radars</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Metuku%20Shyamsunder">Metuku Shyamsunder</a>, <a href="https://publications.waset.org/abstracts/search?q=Kakarla%20Subbarao"> Kakarla Subbarao</a>, <a href="https://publications.waset.org/abstracts/search?q=P.%20Prasanna"> P.

From this received signal, by extracting various parameters such as round trip delay, Doppler frequency it is possible to find distance, speed, altitude, etc. However, nowadays as the technology increases, intruders are intercepting transmitted signal as it reaches them, and they will be extracting the characteristics and trying to modify them. So there is a need to develop a system whose signal cannot be identified by no cooperative intercept receivers. That is why LPI radars came into existence.

We present heuristics based on a Mixed Integer Program (MIP) formulation for local optimization. These methods provide flexibility in scheduling new trains with varying speed and delays and improve utilization of infrastructure. We propose methods that provide a robust solution with hundreds of trains being scheduled over a portion of the railway network without significant increases in delay. We also provide techniques to validate the nominal schedules thus generated over global correlated variations in travel times thereby enabling us to detect conflicts arising due to delays.

Empowering these autonomous with the intelligence to cooperate amongst themselves leads to a more efficient use of the resources available to them. This paper proposes a demonstration of a swarm algorithm implemented on a group of autonomous vehicles. The demonstration involves two ground bots and an aerial drone which cooperate amongst them to locate an object of interest. The object of interest is modelled using a high-intensity light source which acts as a beacon. The ground bots are light sensitive and move towards the beacon. The ground bots and the drone traverse in random paths and jointly locate the beacon. This finds application in various scenarios in where human interference is difficult such as search and rescue during natural disasters, delivering crucial packages in perilous situations, etc. Experimental results show that the modified swarm algorithm implemented in this system has better performance compared to fully random based moving algorithm for object localization and tracking. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=swarm%20algorithm" title="swarm algorithm">swarm algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=object%20localization" title=" object localization"> object localization</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20bots" title=" ground bots"> ground bots</a>, <a href="https://publications.waset.org/abstracts/search?q=drone" title=" drone"> drone</a>, <a href="https://publications.waset.org/abstracts/search?q=beacon" title=" beacon"> beacon</a> </p> <a href="https://publications.waset.org/abstracts/52839/swarm-optimization-of-unmanned-vehicles-and-object-localization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52839.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">257</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Variability of Metal Composition and Concentrations in Road Dust in the Urban Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandya%20Mummullage">Sandya Mummullage</a>, <a href="https://publications.waset.org/abstracts/search?q=Prasanna%20Egodawatta"> Prasanna Egodawatta</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashantha%20Goonetilleke"> Ashantha Goonetilleke</a>, <a href="https://publications.waset.org/abstracts/search?q=Godwin%20A.%20Ayoko"> Godwin A.

Hence, assessing the metal composition and concentration in urban road dust is a high priority. This study investigated the variability of metal composition and concentrations in road dust in four different urban land uses in Gold Coast, Australia. Samples from 16 road sites were collected and tested for selected 12 metal species. The data set was analyzed using both univariate and multivariate techniques. Outcomes of the data analysis revealed that the metal concentrations inroad dust differs considerably within and between different land uses. Iron, aluminum, magnesium and zinc are the most abundant in urban land uses. It was also noted that metal species such as titanium, nickel, copper, and zinc have the highest concentrations in industrial land use. The study outcomes revealed that soil and traffic related sources as key sources of metals deposited on road surfaces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metals%20build-up" title="metals build-up">metals build-up</a>, <a href="https://publications.waset.org/abstracts/search?q=pollutant%20accumulation" title=" pollutant accumulation"> pollutant accumulation</a>, <a href="https://publications.waset.org/abstracts/search?q=stormwater%20quality" title=" stormwater quality"> stormwater quality</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20road%20dust" title=" urban road dust"> urban road dust</a> </p> <a href="https://publications.waset.org/abstracts/2248/variability-of-metal-composition-and-concentrations-in-road-dust-in-the-urban-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2248.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">292</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Attention Based Fully Convolutional Neural Network for Simultaneous Detection and Segmentation of Optic Disc in Retinal Fundus Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandip%20Sadhukhan">Sandip Sadhukhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Arpita%20Sarkar"> Arpita Sarkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Debprasad%20Sinha"> Debprasad Sinha</a>, <a href="https://publications.waset.org/abstracts/search?q=Goutam%20Kumar%20Ghorai"> Goutam Kumar Ghorai</a>, <a href="https://publications.waset.org/abstracts/search?q=Gautam%20Sarkar"> Gautam Sarkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashis%20K.%20Dhara"> Ashis K.

The paper presents an accurate and fast optic disc detection and segmentation method using an attention based fully convolutional network. The network is trained from scratch using the fundus images of extended MESSIDOR database and the trained model is used for segmentation of optic disc. The false positives are removed based on morphological operation and shape features. The result is evaluated using three-fold cross-validation on six public fundus image databases such as DIARETDB0, DIARETDB1, DRIVE, AV-INSPIRE, CHASE DB1 and MESSIDOR. The attention based fully convolutional network is robust and effective for detection and segmentation of optic disc in the images affected by diabetic retinopathy and it outperforms existing techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attention-based%20fully%20convolutional%20network" title="attention-based fully convolutional network">attention-based fully convolutional network</a>, <a href="https://publications.waset.org/abstracts/search?q=optic%20disc%20detection%20and%20segmentation" title=" optic disc detection and segmentation"> optic disc detection and segmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=retinal%20fundus%20image" title=" retinal fundus image"> retinal fundus image</a>, <a href="https://publications.waset.org/abstracts/search?q=screening%20of%20ocular%20diseases" title=" screening of ocular diseases"> screening of ocular diseases</a> </p> <a href="https://publications.waset.org/abstracts/112293/attention-based-fully-convolutional-neural-network-for-simultaneous-detection-and-segmentation-of-optic-disc-in-retinal-fundus-images" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112293.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Variation of Base Width of a Typical Concrete Gravity Dam under Different Seismic Conditions Using Static Seismic Loading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prasanna%20Kumar%20Khaund">Prasanna Kumar Khaund</a>, <a href="https://publications.waset.org/abstracts/search?q=Sukanya%20Talukdar"> Sukanya Talukdar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A concrete gravity dam is a major hydraulic structure and it is very essential to consider the earthquake forces, to get a proper design base width, so that the entire weight of the dam resists the overturning moment due to earthquake and other forces. The main objective of this study is to obtain the design base width of a dam for different seismic conditions by varying the earthquake coefficients in both vertical and horizontal directions. This shall be done by equating the factor of safety against overturning, factor of safety against sliding and factor of safety against shear friction factor for a dam with their limiting values, under both tail water and no tail water condition. The shape of the Mettur dam in India is considered for the study. The study has been done taking a constant head of water at the reservoir, which is the maximum reservoir water level and a constant height of tail water. Using linear approximation method of Newton Raphson, the obtained equations against different factors of safety under different earthquake conditions are solved using a programme in C++ to get different values of base width of dam for varying earthquake conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design%20base%20width" title="design base width">design base width</a>, <a href="https://publications.waset.org/abstracts/search?q=horizontal%20earthquake%20coefficient" title=" horizontal earthquake coefficient"> horizontal earthquake coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=tail%20water" title=" tail water"> tail water</a>, <a href="https://publications.waset.org/abstracts/search?q=vertical%20earthquake%20coefficient" title=" vertical earthquake coefficient"> vertical earthquake coefficient</a> </p> <a href="https://publications.waset.org/abstracts/72683/variation-of-base-width-of-a-typical-concrete-gravity-dam-under-different-seismic-conditions-using-static-seismic-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72683.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">282</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Metallurgical Analysis of Surface Defect in Telescopic Front Fork</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Souvik%20Das">Souvik Das</a>, <a href="https://publications.waset.org/abstracts/search?q=Janak%20Lal"> Janak Lal</a>, <a href="https://publications.waset.org/abstracts/search?q=Arthita%20Dey"> Arthita Dey</a>, <a href="https://publications.waset.org/abstracts/search?q=Goutam%20Mukhopadhyay"> Goutam Mukhopadhyay</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandip%20Bhattacharya"> Sandip Bhattacharya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Telescopic Front Fork (TFF) used in two wheelers, mainly motorcycle, is made from high strength steel, and is manufactured by high frequency induction welding process wherein hot rolled and pickled coils are used as input raw material for rolling of hollow tubes followed by heat treatment, surface treatment, cold drawing, tempering, etc. The final application demands superior quality TFF tubes w.r.t. surface finish and dimensional tolerances. This paper presents the investigation of two different types of failure of fork during operation. The investigation consists of visual inspection, chemical analysis, characterization of microstructure, and energy dispersive spectroscopy. In this paper, comprehensive investigations of two failed tube samples were investigated. In case of Sample #1, the result revealed that there was a pre-existing crack, known as hook crack, which leads to the cracking of the tube. Metallographic examination exhibited that during field operation the pre-existing hook crack was surfaced out leading to crack in the pipe. In case of Sample #2, presence of internal oxidation with decarburised grains inside the material indicates origin of the defect from slab stage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=telescopic%20front%20fork" title="telescopic front fork">telescopic front fork</a>, <a href="https://publications.waset.org/abstracts/search?q=induction%20welding" title=" induction welding"> induction welding</a>, <a href="https://publications.waset.org/abstracts/search?q=hook%20crack" title=" hook crack"> hook crack</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20oxidation" title=" internal oxidation"> internal oxidation</a> </p> <a href="https://publications.waset.org/abstracts/96121/metallurgical-analysis-of-surface-defect-in-telescopic-front-fork" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96121.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">131</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Predicting Potential Protein Therapeutic Candidates from the Gut Microbiome </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prasanna%20Ramachandran">Prasanna Ramachandran</a>, <a href="https://publications.waset.org/abstracts/search?q=Kareem%20Graham"> Kareem Graham</a>, <a href="https://publications.waset.org/abstracts/search?q=Helena%20Kiefel"> Helena Kiefel</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunit%20Jain"> Sunit Jain</a>, <a href="https://publications.waset.org/abstracts/search?q=Todd%20DeSantis"> Todd DeSantis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Microbes that reside inside the mammalian GI tract, commonly referred to as the gut microbiome, have been shown to have therapeutic effects in animal models of disease. We hypothesize that specific proteins produced by these microbes are responsible for this activity and may be used directly as therapeutics. To speed up the discovery of these key proteins from the big-data metagenomics, we have applied machine learning techniques. Using amino acid sequences of known epitopes and their corresponding binding partners, protein interaction descriptors (PID) were calculated, making a positive interaction set. A negative interaction dataset was calculated using sequences of proteins known not to interact with these same binding partners. Using Random Forest and positive and negative PID, a machine learning model was trained and used to predict interacting versus non-interacting proteins. Furthermore, the continuous variable, cosine similarity in the interaction descriptors was used to rank bacterial therapeutic candidates. Laboratory binding assays were conducted to test the candidates for their potential as therapeutics. Results from binding assays reveal the accuracy of the machine learning prediction and are subsequently used to further improve the model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=protein-interactions" title="protein-interactions">protein-interactions</a>, <a href="https://publications.waset.org/abstracts/search?q=machine-learning" title=" machine-learning"> machine-learning</a>, <a href="https://publications.waset.org/abstracts/search?q=metagenomics" title=" metagenomics"> metagenomics</a>, <a href="https://publications.waset.org/abstracts/search?q=microbiome" title=" microbiome"> microbiome</a> </p> <a href="https://publications.waset.org/abstracts/62501/predicting-potential-protein-therapeutic-candidates-from-the-gut-microbiome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62501.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">376</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">23</span> Investigation of Chord Protocol in Peer to Peer Wireless Mesh Network with Mobility</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Prasanna%20Murali%20Krishna">P.

Structured P2P approaches are widely used in adhoc networks due to its distributed and scalability features. Efficient mechanisms are required to handle the huge amount of data distributed to all peers. The intrinsic characteristics of P2P system makes for easier content distribution when compared to client-server architecture. All the nodes in a P2P network act as both client and server, thus, distributing data takes lesser time when compared to the client-server method. CHORD protocol is a resource routing based where nodes and data items are structured into a 1- dimensional ring. The structured lookup algorithm of Chord is advantageous for distributed P2P networking applications. Though, structured approach improves lookup performance in a high bandwidth wired network it could contribute to unnecessary overhead in overlay networks leading to degradation of network performance. In this paper, the performance of existing CHORD protocol on Wireless Mesh Network (WMN) when nodes are static and dynamic is investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wireless%20mesh%20network%20%28WMN%29" title="wireless mesh network (WMN)">wireless mesh network (WMN)</a>, <a href="https://publications.waset.org/abstracts/search?q=structured%20P2P%0D%0Anetworks" title=" structured P2P networks"> structured P2P networks</a>, <a href="https://publications.waset.org/abstracts/search?q=peer%20to%20peer%20resource%20sharing" title=" peer to peer resource sharing"> peer to peer resource sharing</a>, <a href="https://publications.waset.org/abstracts/search?q=CHORD%20Protocol" title=" CHORD Protocol"> CHORD Protocol</a>, <a href="https://publications.waset.org/abstracts/search?q=DHT" title=" DHT"> DHT</a> </p> <a href="https://publications.waset.org/abstracts/34950/investigation-of-chord-protocol-in-peer-to-peer-wireless-mesh-network-with-mobility" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34950.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">480</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">22</span> Unsafe Abortions in India: Questioning the Propitiousness of MTP Act</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suresh%20Sharma">Suresh Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Neeti%20Goutam"> Neeti Goutam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In India abortions are legal and with the exceedingly liberal and broadened law that was passed in 1971, “Medical Termination of Pregnancy Act” had opened a new window to Women’s’ freedom and choice over their fertility. This paper would like to focus on the factors responsible for or leading to unsafe abortion as well as such high incidence of abortion in India which can help in understanding the ways in which we can prevent this apathy. To study the intricacies involved in delivering safety to womanhood in terms of safe abortion practice which includes more trained personnel, detailed explanation and consequences of conducting an abortion, fine reporting, awareness regarding family planning measures and not only pressurizing them to sterilize immediately after an abortion but also prior to that informing them and lastly easy accessibility of Contraceptives with a educated and brief information on that. Data has been drawn from various sources such as National Family Household Survey (1, 2, 3), Health Management Information System and Annual Health Survey. To safeguard the interest of women when it comes to complications resulting from unsafe abortions, Reproductive Health laid its strict adherence to it in its guidelines. The Government could induce more measures in terms of family planning measures and increase in the number of skilled medical health force, chiefly in rural areas to prevent the illegality of abortions. But before that fine reporting on the number of abortions performed will give an insight to this very issue only then policies and programs will work much better in favor of women. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abortion" title="abortion">abortion</a>, <a href="https://publications.waset.org/abstracts/search?q=MTP%20act" title=" MTP act"> MTP act</a>, <a href="https://publications.waset.org/abstracts/search?q=India" title=" India"> India</a>, <a href="https://publications.waset.org/abstracts/search?q=women" title=" women"> women</a> </p> <a href="https://publications.waset.org/abstracts/21439/unsafe-abortions-in-india-questioning-the-propitiousness-of-mtp-act" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21439.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">358</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">21</span> Failure Analysis of Low Relaxation Prestressed High Carbon Steel Wire During Drawing Operation: A Metallurgical Investigation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Souvik%20Das">Souvik Das</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandip%20%20Bhattacharya"> Sandip Bhattacharya</a>, <a href="https://publications.waset.org/abstracts/search?q=Goutam%20Mukhopadhyay"> Goutam Mukhopadhyay</a>, <a href="https://publications.waset.org/abstracts/search?q=Manashi%20Adhikary"> Manashi Adhikary</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wires breakages during cold drawing are a complex phenomenon; wire breakages may be induced by improper wire-rod quality, inappropriate heat-treated microstructure, and/or lubrication breakdown on the wire surface. A comprehensive metallurgical investigation of failed/broken wire samples is therefore essential for understanding the origin of failure. Frequent breakage of wires during drawing is a matter of serious concern to the wire drawers as it erodes their already slim margins through reduced productivity and loss in yield. The present paper highlights the failure investigation of wires of Low Relaxation Prestressed High Carbon grade during cold drawing due to entrapment of hard constituents detached from the roller entry guide during rolling operations. The hardness measurement of this entrapped location indicates 54.9 Rockwell Hardness as against the rest portion 33.4 Rockwell Hardness. The microstructure chemical analysis and X-ray mapping analysis data of the entrapment location confirmed complex chromium carbide originated from D2-steel used in entry guide during the rolling process. Since the harder entrapped phase could not be deformed in the same manner as the parent phase, the failure of the wire rod occurs during hot rolling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LRPC" title="LRPC">LRPC</a>, <a href="https://publications.waset.org/abstracts/search?q=D2-steel" title=" D2-steel"> D2-steel</a>, <a href="https://publications.waset.org/abstracts/search?q=chromium%20carbide" title=" chromium carbide"> chromium carbide</a>, <a href="https://publications.waset.org/abstracts/search?q=roller%20guide" title=" roller guide"> roller guide</a> </p> <a href="https://publications.waset.org/abstracts/106416/failure-analysis-of-low-relaxation-prestressed-high-carbon-steel-wire-during-drawing-operation-a-metallurgical-investigation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106416.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">159</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">20</span> Rapid Biosynthesis of Silver Nanoparticles Using Trachyspermum Ammi</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Kumar%20Meena">Rajesh Kumar Meena</a>, <a href="https://publications.waset.org/abstracts/search?q=Suman%20Jhajharia"> Suman Jhajharia</a>, <a href="https://publications.waset.org/abstracts/search?q=Goutam%20Chakraborty"> Goutam Chakraborty</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Plasmonic silver nanoparticles (Ag NPs) was synthesized by chemical reduction method using Trachyspermum Ammi (TA, Ajwain) seeds extract in aqueous medium and AgNO3 solution at different time interval. Reaction time, and concentration of AgNO3 and TA could accelerate the reduction rate of Ag+ and affect AgNPs size and concentration of NPs. Surface plasmon resonance band centered at 420-430 nm (88.78nm) was recognised as first exitonic peak of UV-Vis absorption spectra of AgNPs that used to calculate the particle size (10-30 nm). FTIR results TA supported AgNPs showed decrease in intensity of peaks at 3394, 1716 and 1618 cm-1 with respect to the plain TA indicating the involvement of O-H, carbonyl group and C=C stretching in formation of TA-AgNPs aggregates. The C-O-C and C-N stretching suggested the presence of many phytochemicals on the surface of the NPs. Impedance study reveals that at low concentration of TA the rate of charge transfer is in TA-AgNPs aggregates, found higher than the higher TA concentration condition that confirms the stability of AgNPs in water.

Both the defects are believed to be originating from distinctly different sources having different mechanisms of formation. However, due to their similar physical appearance, RIS and RISc are generally confused with each other and hence attaining the exact root cause for elimination of the defect becomes difficult. RIS appears irregular in shape, sometimes scattered, and always oriented in rolling direction. RISc is generally oval shaped, having identifiable pointed edges and mostly oriented in rolling direction. Visually, RIS appears to be greyish in colour whereas RISc is whitish in colour. Both the defects have quite random occurrence and do not leave any imprints on the reverse-side of the sheet. In the current study, an attempt has been made to differentiate these two similar looking surface defects using various metallographic and characterization techniques. Systematic experiments have been carried out to identify possible mechanisms of formation of these defects. Detailed characterization revealed basic differences between RIS and RISc with respect to their surface morphology. To summarize, RIS was observed as a residue of an otherwise under-pickled scale patch on surface, after it has been subjected to cold rolling and annealing in a batch/continuous furnace. Whereas RISc was found to be a localized rubbing of the surface, at the time of cold rolling itself, resulting in a rough surface texture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=annealing" title="annealing">annealing</a>, <a href="https://publications.waset.org/abstracts/search?q=rolled%20in%20scale" title=" rolled in scale"> rolled in scale</a>, <a href="https://publications.waset.org/abstracts/search?q=rolled%20in%20scum" title=" rolled in scum"> rolled in scum</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20panel" title=" skin panel "> skin panel </a> </p> <a href="https://publications.waset.org/abstracts/107183/study-of-rolled-in-scale-and-rolled-in-scum-in-automotive-grade-cold-rolled-annealed-steel-sheet" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107183.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">18</span> High Prevalence of Multi-drug Resistant Diarrheagenic Escherichia coli among Hospitalised Diarrheal Patients in Kolkata, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Debjani%20Ghosh">Debjani Ghosh</a>, <a href="https://publications.waset.org/abstracts/search?q=Goutam%20Chowdhury"> Goutam Chowdhury</a>, <a href="https://publications.waset.org/abstracts/search?q=Prosenjit%20Samanta"> Prosenjit Samanta</a>, <a href="https://publications.waset.org/abstracts/search?q=Asish%20Kumar%20Mukhopadhyay"> Asish Kumar Mukhopadhyay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Acute diarrhoea caused by diarrheagenic Escherichia coli (DEC) is one of the major public health problem in developing countries, mainly in Asia and Africa. DEC consists of six pathogroups, but the majority of the cases were associated with the three pathogropus, enterotoxigenic E. coli (ETEC), enteroaggregative E. coli (EAEC), and enteropathogenic E. coli (EPEC). Hence, we studied the prevalence and antimicrobial resistance of these three major DEC pathogroups in hospitalized diarrheal patients in Kolkata, India, during 2012-2019 with a large sample size. 8,891 stool samples were processed, and 7.8% of them was identified as DEC infection screened by multiplex PCR, in which ETEC was most common (47.7%) followed by EAEC (38.4%) and EPEC (13.9%). Clinical patient history suggested that children <5 years of age were mostly affected with ETEC and EAEC, whereas people within >5-14 years of age were significantly associated with EPEC and ETEC infections. Antibiogram profile showed a high prevalence of multidrug resistant (MDR) isolates among DEC (56.9%), in which 9% were resistant to antibiotics of six different antimicrobial classes. Screening of the antibiotic resistance conferring genes in DEC showed the presence of blaCTX-M (30.2%) in highest number followed by blaTEM (27.5%), tetB (18%), sul2 (12.6%), strA (11.8%), aadA1 (9.8%), blaOXA-1 (9%), dfrA1 (1.6%) and blaSHV (1.2%) which indicates the existence of mobile genetic elements in those isolates. Therefore, the presence of MDR DEC strains in higher number alarms the public health authorities to take preventive measures before the upsurge of the DEC caused diarrhea cases in near future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diarrheagenic%20escherichia%20coli" title="diarrheagenic escherichia coli">diarrheagenic escherichia coli</a>, <a href="https://publications.waset.org/abstracts/search?q=ETEC" title=" ETEC"> ETEC</a>, <a href="https://publications.waset.org/abstracts/search?q=EAEC" title=" EAEC"> EAEC</a>, <a href="https://publications.waset.org/abstracts/search?q=EPEC" title=" EPEC"> EPEC</a> </p> <a href="https://publications.waset.org/abstracts/143560/high-prevalence-of-multi-drug-resistant-diarrheagenic-escherichia-coli-among-hospitalised-diarrheal-patients-in-kolkata-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143560.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">161</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">17</span> Effect of Particle Size and Concentration of Pomegranate (Punica granatum l.)

Madhujith</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lipid oxidation is an important process that affects the shelf life of edible oils. Oxidation produces off flavors, off odors and chemical compounds that lead to adverse health effects. Chemical mechanisms such as autoxidation, photo-oxidation and thermal oxidation are responsible for lipid oxidation. Refined, Bleached and Deodorized (RBD) coconut oil, Virgin Coconut Oil (VCO) and corn oil are widely used plant oils. Pomegranate fruit is known to possess high antioxidative efficacy. Peel of pomegranate contains high antioxidant activity than aril and pulp membrane. The study attempted to study the effect of particle size and concentration of pomegranate peel powder on suppression of oxidation of RBD coconut oil, VCO and corn oil. Pomegranate peel powder was incorporated into each oil sample as micro (< 250 µm) and nano particles (280 - 300 nm) at 100 ppm and 200 ppm concentrations. The control sample of each oil was prepared, devoid of pomegranate peel powder. The stability of oils against autoxidation was evaluated by storing oil samples at 60 °C for 28 days. The level of oxidation was assessed by peroxide value and thiobarbituric acid reactive substances on 0,1,3,5,7,14 and 28 day, respectively. VCO containing pomegranate particles of 280 - 300 nm at 200 ppm showed the highest oxidative stability followed by RBD coconut oil and corn oil. Results revealed that pomegranate peel powder with 280 - 300 nm particle size at 200 ppm concentration was the best in mitigating oxidation of RBD coconut oil, VCO and corn oil. There is a huge potential of utilizing pomegranate peel powder as an antioxidant agent in reducing oxidation of edible plant oils. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title="antioxidant">antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=autoxidation" title=" autoxidation"> autoxidation</a>, <a href="https://publications.waset.org/abstracts/search?q=micro%20particles" title=" micro particles"> micro particles</a>, <a href="https://publications.waset.org/abstracts/search?q=nano%20particles" title=" nano particles"> nano particles</a>, <a href="https://publications.waset.org/abstracts/search?q=pomegranate%20peel%20powder" title=" pomegranate peel powder"> pomegranate peel powder</a> </p> <a href="https://publications.waset.org/abstracts/35648/effect-of-particle-size-and-concentration-of-pomegranate-punica-granatum-l-peel-powder-on-suppression-of-oxidation-of-edible-plant-oils" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35648.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">453</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">16</span> Effect of Solvents in the Extraction and Stability of Anthocyanin from the Petals of Caesalpinia pulcherrima for Natural Dye-Sensitized Solar Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Prabavathy">N.

Muthukumarasamy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dye sensitized solar cell (DSSC) has become a significant research area due to their fundamental and scientific importance in the area of energy conversion. Synthetic dyes as sensitizer in DSSC are efficient and durable but they are costlier, toxic and have the tendency to degrade. Natural sensitizers contain plant pigments such as anthocyanin, carotenoid, flavonoid, and chlorophyll which promote light absorption as well as injection of charges to the conduction band of TiO2 through the sensitizer. But, the efficiency of natural dyes is not up to the mark mainly due to instability of the pigment such as anthocyanin. The stability issues in vitro are mainly due to the effect of solvents on extraction of anthocyanins and their respective pH. Taking this factor into consideration, in the present work, the anthocyanins were extracted from the flower Caesalpinia pulcherrima (C. pulcherrimma) with various solvents and their respective stability and pH values are discussed. The usage of citric acid as solvent to extract anthocyanin has shown good stability than other solvents. It also helps in enhancing the sensitization properties of anthocyanins with Titanium dioxide (TiO2) nanorods. The IPCE spectra show higher photovoltaic performance for dye sensitized TiO2nanorods using citric acid as solvent. The natural DSSC using citric acid as solvent shows a higher efficiency compared to other solvents. Hence citric acid performs to be a safe solvent for natural DSSC in boosting the photovoltaic performance and maintaining the stability of anthocyanins. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Caesalpinia%20pulcherrima" title="Caesalpinia pulcherrima">Caesalpinia pulcherrima</a>, <a href="https://publications.waset.org/abstracts/search?q=citric%20acid" title=" citric acid"> citric acid</a>, <a href="https://publications.waset.org/abstracts/search?q=dye%20sensitized%20solar%20cells" title=" dye sensitized solar cells"> dye sensitized solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=TiO%E2%82%82%20nanorods" title=" TiO₂ nanorods"> TiO₂ nanorods</a> </p> <a href="https://publications.waset.org/abstracts/71483/effect-of-solvents-in-the-extraction-and-stability-of-anthocyanin-from-the-petals-of-caesalpinia-pulcherrima-for-natural-dye-sensitized-solar-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71483.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">290</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">15</span> Shared Heart with a Common Atrial Complex and Persistent Right Dorsal Aorta in Conjoined Twins</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20C.%20Prasanna">L.

We have reviewed articles on cardiovascular anomalies in conjoined twins and presenting rarest anomaly in dicephalus parapagus fetus having two heads attached to one body from the neck or upper chest downwards, with a pair of limbs and a set of reproductive organs. Both the twins shared a common thoracic cavity with a single sternum. When the thoracic cavity was opened, a common anterior mediastinum was found. On opening the pericardium, two separate, closely apposed hearts were exposed. The two cardia are placed side by side. The left heart was slightly larger than the right and were joined at the atrial levels. Four atrial appendages were present, two for each twin. The atrial complex was a common chamber posterior to the ventricles. A single large tributary which could be taken as inferior vena cava drains into the common atrial chamber. In this case, the heart could not be assigned to either twin and therefore, it is referred to as the shared heart within a common pericardial sac. The right and left descending thoracic aorta have joined with each other just above the diaphragm to form a common descending thoracic aorta which has an opening in the diaphragm to be continued as common abdominal aorta which has a normal branching pattern. Upon an interior dissection, it is observed that the two atria have a wide communication which could be a wide patent foramen ovale and this common atrial cavity has a communication with a remnant of a possible common sinus venosus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atrium" title="atrium">atrium</a>, <a href="https://publications.waset.org/abstracts/search?q=congenital%20anomaly" title=" congenital anomaly"> congenital anomaly</a>, <a href="https://publications.waset.org/abstracts/search?q=conjoined%20twin" title=" conjoined twin"> conjoined twin</a>, <a href="https://publications.waset.org/abstracts/search?q=sinus%20venosus" title=" sinus venosus"> sinus venosus</a> </p> <a href="https://publications.waset.org/abstracts/63812/shared-heart-with-a-common-atrial-complex-and-persistent-right-dorsal-aorta-in-conjoined-twins" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63812.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">394</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">14</span> Vascular Crossed Aphasia in Dextrals: A Study on Bengali-Speaking Population in Eastern India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Durjoy%20Lahiri">Durjoy Lahiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Vishal%20Madhukar%20Sawale"> Vishal Madhukar Sawale</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashwani%20Bhat"> Ashwani Bhat</a>, <a href="https://publications.waset.org/abstracts/search?q=Souvik%20Dubey"> Souvik Dubey</a>, <a href="https://publications.waset.org/abstracts/search?q=Gautam%20Das"> Gautam Das</a>, <a href="https://publications.waset.org/abstracts/search?q=Biman%20Kanti%20Roy"> Biman Kanti Roy</a>, <a href="https://publications.waset.org/abstracts/search?q=Suparna%20Chatterjee"> Suparna Chatterjee</a>, <a href="https://publications.waset.org/abstracts/search?q=Goutam%20Gangopadhyay"> Goutam Gangopadhyay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Crossed aphasia has been an area of considerable interest for cognitive researchers as it offers a fascinating insight into cerebral lateralization for language function. We conducted an observational study in the stroke unit of a tertiary care neurology teaching hospital in eastern India on subjects with crossed aphasia over a period of four years. During the study period, we detected twelve cases of crossed aphasia in strongly right-handed patients, caused by ischemic stroke. The age, gender, vernacular language and educational status of the patients were noted. Aphasia type and severity were assessed using Bengali version of Western Aphasia Battery (validated). Computed tomography, magnetic resonance imaging and angiography were used to evaluate the location and extent of the ischemic lesion in brain. Our series of 12 cases of crossed aphasia included 7 male and 5 female with mean age being 58.6 years. Eight patients were found to have Broca’s aphasia, 3 had trans-cortical motor aphasia and 1 patient suffered from global aphasia. Nine patients were having very severe aphasia and 3 suffered from mild aphasia. Mirror-image type of crossed aphasia was found in 3 patients, whereas 9 had anomalous variety. In our study crossed aphasia was found to be more frequent in males. Anomalous pattern was more common than mirror-image. Majority of the patients had motor-type aphasia and no patient was found to have pure comprehension deficit. We hypothesize that in Bengali-speaking right-handed population, lexical-semantic system of the language network remains loyal to the left hemisphere even if the phonological output system is anomalously located in the right hemisphere. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aphasia" title="aphasia">aphasia</a>, <a href="https://publications.waset.org/abstracts/search?q=crossed" title=" crossed"> crossed</a>, <a href="https://publications.waset.org/abstracts/search?q=lateralization" title=" lateralization"> lateralization</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20function" title=" language function"> language function</a>, <a href="https://publications.waset.org/abstracts/search?q=vascular" title=" vascular"> vascular</a> </p> <a href="https://publications.waset.org/abstracts/99580/vascular-crossed-aphasia-in-dextrals-a-study-on-bengali-speaking-population-in-eastern-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99580.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">192</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">13</span> Failure Analysis of Recoiler Mandrel Shaft Used for Coiling of Rolled Steel Sheet</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sachin%20Pawar">Sachin Pawar</a>, <a href="https://publications.waset.org/abstracts/search?q=Suman%20Patra"> Suman Patra</a>, <a href="https://publications.waset.org/abstracts/search?q=Goutam%20Mukhopadhyay"> Goutam Mukhopadhyay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The primary function of a shaft is to transfer power. The shaft can be cast or forged and then machined to the final shape. Manufacturing of ~5 m length and 0.6 m diameter shaft is very critical. More difficult is to maintain its straightness during heat treatment and machining operations, which involve thermal and mechanical loads, respectively. During the machining operation of a such forged mandrel shaft, a deflection of 3-4mm was observed. To remove this deflection shaft was pressed at both ends which led to the development of cracks in it. To investigate the root cause of the deflection and cracking, the sample was cut from the failed shaft. Possible causes were identified with the help of a cause and effect diagram. Chemical composition analysis, microstructural analysis, and hardness measurement were done to confirm whether the shaft meets the required specifications or not. Chemical composition analysis confirmed that the material grade was 42CrMo4. Microstructural analysis revealed the presence of untempered martensite, indicating improper heat treatment. Due to this, ductility and impact toughness values were considerably lower than the specification of the mentioned grade. Residual stress measurement of one more bent shaft manufactured by a similar route was done by portable X-ray diffraction(XRD) technique. For better understanding, measurements were done at twelve different locations along the length of the shaft. The occurrence of a high amount of undesirable tensile residual stresses close to the Ultimate Tensile Strength(UTS) of the material was observed. Untempered martensitic structure, lower ductility, lower impact strength, and presence of a high amount of residual stresses all confirmed the improper tempering heat treatment of the shaft. Tempering relieves the residual stresses. Based on the findings of this study, stress-relieving heat treatment was done to remove the residual stresses and deflection in the shaft successfully. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=residual%20stress" title="residual stress">residual stress</a>, <a href="https://publications.waset.org/abstracts/search?q=mandrel%20shaft" title=" mandrel shaft"> mandrel shaft</a>, <a href="https://publications.waset.org/abstracts/search?q=untempered%20martensite" title=" untempered martensite"> untempered martensite</a>, <a href="https://publications.waset.org/abstracts/search?q=portable%20XRD" title=" portable XRD"> portable XRD</a> </p> <a href="https://publications.waset.org/abstracts/107065/failure-analysis-of-recoiler-mandrel-shaft-used-for-coiling-of-rolled-steel-sheet" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107065.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">112</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Effectiveness of Impairment Specified Muscle Strengthening Programme in a Group of Disabled Athletes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20L.%20I.%20Prasanna">A.

General conditioning and strengthening exercises might be ineffective if not sufficiently intense enough or targeted for each participant’s specific impairment. Specific strengthening programme, targeted to the affected body part, are essential to improve the strength of impaired muscles and increase in strength will help reducing the impact of disability. Methods: The muscle strength of hip, knee and ankle joints was assessed in a group of randomly selected disabled athletes, using the Medical Research Council (MRC) grading. Those having muscle strength of grade 4 or less were selected for this study (24 in number) and were given and a custom made exercise program designed to strengthen their hip, knee or ankle joint musculature, according to the muscle or group of muscles affected. Effectiveness of the strengthening program was assessed after a period of 3 months. Results: Statistical analysis was done using the Minitab 16 statistical software. A Mann-Whitney U test was used to compare the strength of muscle group before and after exercise programme. A significant difference was observed after the three month strengthening program for knee flexors (Left and Right) (P =0.0889, 0.0312) hip flexors (left and right) (P=0.0312, 0.0466), hip extensors (Left and Right) (P=0.0478, 0.0513), ankle plantar flexors (Left and Right) (P=0.0466, 0.0423) and right ankle dorsiflexors (P= 0.0337). No significant difference of strength was observed after the strengthening program in the knee extensors (left and right), hip abductors (left and right) and left ankle dorsiflexors. Conclusion: Impairment specific exercise programme appear to be beneficial for disabled athletes to significantly improve the muscle strength of the affected joints. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=muscle%20strengthening%20programme" title="muscle strengthening programme">muscle strengthening programme</a>, <a href="https://publications.waset.org/abstracts/search?q=disabled%20athletes" title=" disabled athletes"> disabled athletes</a>, <a href="https://publications.waset.org/abstracts/search?q=physiotherapy" title=" physiotherapy"> physiotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitation%20sciences" title=" rehabilitation sciences"> rehabilitation sciences</a> </p> <a href="https://publications.waset.org/abstracts/1783/effectiveness-of-impairment-specified-muscle-strengthening-programme-in-a-group-of-disabled-athletes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1783.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">357</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Studies on Radio Frequency Sputtered Copper Zinc Tin Sulphide Absorber Layers for Thin Film Solar Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20Balaji">G.

In the present study, Cu2ZnSnS4 thin films were prepared on soda lime glass using (CuS, ZnS, SnS) targets and were deposited by three different stacking orders, using RF Magnetron sputtering. The substrate temperature was fixed at 300 °C during the depositions. CZTS thin films were characterized using X-ray diffraction, X-ray photoelectron spectroscopy, Raman spectroscopy and UV-Vis-NIR spectroscopy. All the samples exhibited X-ray peaks pertaining to (112) kesterite phase of CZTS, along with the presence of a predominant wurtzite CZTS phase. X-ray photoelectron spectroscopy revealed the presence of all the elements in all the samples. The change in stacking order clearly shows that it affects the structural and phase properties of the films. Relative atomic concentrations of Zn, Cu, Sn and S, which are determined by high-resolution XPS core level spectra integrated peak areas revealed that the CZTS films exhibit inhomogeneity in both stoichiometry and elemental composition. Raman spectroscopy studies on the film showed the presence of CZTS phase. The energy band gap of the CZTS thin films was found to be in the range of 1.5 eV to 1.6 eV. The films were then annealed at 450 °C for 5 hrs and it was found that the predominant nature of the X-ray peaks has transformed from Wurtzite to Kesterite phase which is highly desirable for absorber layers in thin film solar cells. The optimized CZTS layer was used as an absorber layer in thin film solar cells. ZnS and CdS were used as buffer layers which in turn prepared by Hot wall epitaxy technique. Gallium doped Zinc oxide was used as a transparent conducting oxide. The solar cell structure Glass/Mo/CZTS/CdS or ZnS/GZO has been fabricated, and solar cell parameters were measured. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earth-abundant" title="earth-abundant">earth-abundant</a>, <a href="https://publications.waset.org/abstracts/search?q=Kesterite" title=" Kesterite"> Kesterite</a>, <a href="https://publications.waset.org/abstracts/search?q=RF%20sputtering" title=" RF sputtering"> RF sputtering</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20film%20solar%20cells" title=" thin film solar cells"> thin film solar cells</a> </p> <a href="https://publications.waset.org/abstracts/71511/studies-on-radio-frequency-sputtered-copper-zinc-tin-sulphide-absorber-layers-for-thin-film-solar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71511.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">280</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Candida antartica Lipase Assisted Enrichment of n-3 PUFA in Indian Sardine Oil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prasanna%20Belur">Prasanna Belur</a>, <a href="https://publications.waset.org/abstracts/search?q=P.%20R.%20Ashwini"> P.

Regupathi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Indian oil sardine (Sardinella longiceps) are one of the richest and cheapest sources of n-3 polyunsaturated fatty acids (n-3 PUFA) such as Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA). The health benefits conferred by n-3 PUFA upon consumption, in the prevention and treatment of coronary, neuromuscular, immunological disorders and allergic conditions are well documented. Natural refined Indian Sardine oil generally contain about 25% (w/w) n-3 PUFA along with various unsaturated and saturated fatty acids in the form of mono, di, and triglycerides. Having high concentration of n-3 PUFA content in the glyceride form is most desirable for human consumption to avail maximum health benefits. Thus, enhancing the n-3 PUFA content while retaining it in the glyceride form with green technology is the need of the hour. In this study, refined Indian Sardine oil was subjected to selective hydrolysis by Candida antartica lipase to enhance n-3 PUFA content. The degree of hydrolysis and enhancement of n-3 PUFA content was estimated by determining acid value, Iodine value, EPA and DHA content (by Gas Chromatographic methods after derivitization) before and after hydrolysis. Various reaction parameters such as pH, temperature, enzyme load, lipid to aqueous phase volume ratio and incubation time were optimized by conducting trials with one parameter at a time approach. Incubating enzyme solution with refined sardine oil with a volume ratio of 1:1, at pH 7.0, for 60 minutes at 50 °C, with an enzyme load of 60 mg/ml was found to be optimum. After enzymatic treatment, the oil was subjected to refining to remove free fatty acids and moisture content using previously optimized refining technology. Enzymatic treatment at the optimal conditions resulted in 12.11 % enhancement in Degree of hydrolysis. Iodine number had increased by 9.7 % and n-3 PUFA content was enhanced by 112 % (w/w). Selective enhancement of n-3 PUFA glycerides, eliminating saturated and unsaturated fatty acids from the oil using enzyme is an interesting preposition as this technique is environment-friendly, cost effective and provide natural source of n-3 PUFA rich oil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Candida%20antartica" title="Candida antartica">Candida antartica</a>, <a href="https://publications.waset.org/abstracts/search?q=lipase" title=" lipase"> lipase</a>, <a href="https://publications.waset.org/abstracts/search?q=n-3%20polyunsaturated%20fatty%20acids" title=" n-3 polyunsaturated fatty acids"> n-3 polyunsaturated fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=sardine%20oil" title=" sardine oil"> sardine oil</a> </p> <a href="https://publications.waset.org/abstracts/67470/candida-antartica-lipase-assisted-enrichment-of-n-3-pufa-in-indian-sardine-oil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67470.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">233</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">9</span> Unusual Weld Failures of Rotary Compressor during Hydraulic Tests: Analysis revealed Boron Induced Cracking in Fusion Zone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kaushal%20Kishore">Kaushal Kishore</a>, <a href="https://publications.waset.org/abstracts/search?q=Vaibhav%20Jain"> Vaibhav Jain</a>, <a href="https://publications.waset.org/abstracts/search?q=Hrishikesh%20Jugade"> Hrishikesh Jugade</a>, <a href="https://publications.waset.org/abstracts/search?q=Saurabh%20Hadas"> Saurabh Hadas</a>, <a href="https://publications.waset.org/abstracts/search?q=Manashi%20Adhikary"> Manashi Adhikary</a>, <a href="https://publications.waset.org/abstracts/search?q=Goutam%20Mukhopadhyay"> Goutam Mukhopadhyay</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandip%20Bhattacharyya"> Sandip Bhattacharyya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rotary air compressors in air conditioners are used to suck excessive volume of air from the atmosphere in a small space to provide drive to the components attached to them. Hydraulic test is one of the most important methods to decide the suitability of these components for usage. In the present application, projection welding is used to join the hot rolled steel sheets after forming for manufacturing of air compressors. These sheets belong to two different high strength low alloy (HSLA) steel grades. It was observed that one batch of compressors made of a particular grade was cracking from the weld, whereas those made of another grade were passing the hydraulic tests. Cracking was repeatedly observed from the weld location. A detailed comparative study of the compressors which failed and successfully passed pressure tests has been presented. Location of crack initiation was identified to be the interface of fusion zone/heat affected zone. Shear dimples were observed on the fracture surface confirming the ductile mode of failure. Hardness profile across the weld revealed a sharp rise in hardness in the fusion zone. This was attributed to the presence of untempered martensitic lath in the fusion zone. A sharp metallurgical notch existed at the heat affected zone/fusion zone interface due to transition in microstructure from acicular ferrite and bainite in HAZ to untempered martensite in the fusion zone. In contrast, welds which did not fail during the pressure tests showed a smooth hardness profile with no abnormal rise in hardness in the fusion zone. The bainitic microstructure was observed in the fusion zone of successful welds. This difference in microstructural constituents in the fusion zone was attributed to the presence of a small amount of boron (0.002 wt. %) in the sheets which were cracking. Trace amount of boron is known to substantially increase the hardenability of HSLA steel, and cooling rate during resolidification in the fusion zone is sufficient to form martensite. Post-weld heat treatment was recommended to transform untempered martensite to tempered martensite with lower hardness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compressor" title="compressor">compressor</a>, <a href="https://publications.waset.org/abstracts/search?q=cracking" title=" cracking"> cracking</a>, <a href="https://publications.waset.org/abstracts/search?q=martensite" title=" martensite"> martensite</a>, <a href="https://publications.waset.org/abstracts/search?q=weld" title=" weld"> weld</a>, <a href="https://publications.waset.org/abstracts/search?q=boron" title=" boron"> boron</a>, <a href="https://publications.waset.org/abstracts/search?q=hardenability" title=" hardenability"> hardenability</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20strength%20low%20alloy%20steel" title=" high strength low alloy steel"> high strength low alloy steel</a> </p> <a href="https://publications.waset.org/abstracts/107209/unusual-weld-failures-of-rotary-compressor-during-hydraulic-tests-analysis-revealed-boron-induced-cracking-in-fusion-zone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107209.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">167</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">8</span> Durability of Functionally Graded Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prasanna%20Kumar%20Acharya">Prasanna Kumar Acharya</a>, <a href="https://publications.waset.org/abstracts/search?q=Mausam%20Kumari%20Yadav"> Mausam Kumari Yadav</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cement concrete has emerged as the most consumed construction material. It has also dominated all other construction materials because of its versatility. Apart from numerous advantages it has a disadvantage concerning durability. The large structures constructed with cement concrete involving the consumption of huge natural materials remain in serviceable condition for 5 – 7 decades only while structures made with stones stand for many centuries. The short life span of structures not only affects the economy but also affects the ecology greatly. As such, the improvement of durability of cement concrete is a global concern and scientists around the globe are trying for this purpose. Functionally graded concrete (FGC) is an exciting development. In contrast to conventional concrete, FGC demonstrates different characteristics depending on its thickness, which enables it to conform to particular structural specifications. The purpose of FGC is to improve the performance and longevity of conventional concrete structures with cutting-edge building materials. By carefully distributing various kinds and amounts of reinforcements, additives, mix designs and/or aggregates throughout the concrete matrix, this variety is produced. A key component of functionally graded concrete's performance is its durability, which affects the material's capacity to tolerate aggressive environmental influences and load-bearing circumstances. This paper reports the durability of FGC made using Portland slag cement (PSC). For this purpose, control concretes (CC) of M20, M30 and M40 grades were designed. Single-layered samples were prepared using each grade of concrete. Further using combinations of M20 + M30, M30 + M40 and M40 + M20, doubled layered concrete samples in a depth ratio of 1:1 was prepared those are herein called FGC samples. The efficiency of FGC samples was compared with that of the higher-grade concrete of parent materials in terms of compressive strength, water absorption, sorptivity, acid resistance, sulphate resistance, chloride resistance and abrasion resistance. The properties were checked at the age of 28 and 91 days. Apart from strength and durability parameters, the microstructure of CC and FGC were studied in terms of X-ray diffraction, scanning electron microscopy and energy-dispersive X-ray. The result of the study revealed that there is an increase in the efficiency of concrete evaluated in terms of strength and durability when it is made functionally graded using a layered technology having different grades of concrete in layers. The results may help to enhance the efficiency of structural concrete and its durability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fresh%20on%20compacted" title="fresh on compacted">fresh on compacted</a>, <a href="https://publications.waset.org/abstracts/search?q=functionally%20graded%20concrete" title=" functionally graded concrete"> functionally graded concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=acid" title=" acid"> acid</a>, <a href="https://publications.waset.org/abstracts/search?q=chloride" title=" chloride"> chloride</a>, <a href="https://publications.waset.org/abstracts/search?q=sulphate%20test" title=" sulphate test"> sulphate test</a>, <a href="https://publications.waset.org/abstracts/search?q=sorptivity" title=" sorptivity"> sorptivity</a>, <a href="https://publications.waset.org/abstracts/search?q=abrasion" title=" abrasion"> abrasion</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20absorption%20test" title=" water absorption test"> water absorption test</a> </p> <a href="https://publications.waset.org/abstracts/191321/durability-of-functionally-graded-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191321.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">18</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">7</span> Questioning the Predominant Feminism in Ahalya, a Short Film by Sujoy Ghosh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Somya%20Sharma">Somya Sharma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ahalya, the critically acclaimed short film, is known to demolish the gender constructs of the age old myth of Ahalya. The paper tries to crack the overt meaning of the short film by reading between the dialogues and deconstructing the idea of the pseudo feminism in the short film Ahalya by Sujoy Ghosh. The film, by subverting the role of male character by making it seem submissive as compared to the female character's role seems to be just a surface level reading of the text. It seems that Sujoy Ghosh has played not just with changing the paradigm, but also trying to alter the history by doing so. The age old myth of putting Ahalya as a part of the five virgins (panchkanya) of Hindu mythology is explored in the paper. God's manoeuvre cannot be questioned and the two male characters tend to again shape the deed and the life of the female character, Ahalya. It is of importance to note that even in the 21st century, progressive actors like Radhika Apte fail to acknowledge the politics of altering history, not in a progressive way. The film blinds the viewer in the first watch to fall for the female strength and ownership of her sexuality, which is reflected in the opening scene itself where she opens the gate for the police man Indra Sen (representing God Indra who seduced her) who is charmed by her white dress. White, in Hindu mythology, stands for mourning, and this can be a hint towards the prophecy of what is about to come. Ahalya, bold, strong, and confident in this scene seems to be in total ownership of her sexual identity. Further, as the film progresses, control of Ahalya over her acts becomes even more dominant. In the myth of Ahalya, Gautama Maharishi, her husband, who wins her by Brahma's courtesy, curses her for her infidelity. She is then turned into a stone because of the curse and is redeemed when Lord Rama's foot brushes the stone. In the film, it is with the help of Ahalya that Goutam Sadhu turns Indra Sen into a stone doll. Ahalya is seen as a seductress who bewitches Indra Sen, and because the latter falls for the trap laid by the husband wife duo, he is turned into a doll. The attempt made by the paper is to read Ahalya as a character of the stand in wife who is yet again a pawn in the play of Goutama's revenge from Indra (who in the myth is able to escape from any curse or punishment for the act). The paper, therefore, reverts the idea which has till now been signified by the film and attempts to study the feminism this film appropriates. It is essential to break down the structure formed by such overt transgressing films in order to provide a real outlook of how feminism is twisted and moulded according to a man’s wishes. <p
