Due to several fault impending upon it or due to ageing, etc its life gets lowered. So, it becomes necessary to have diagnosis of oil for fault analysis. Due to the chemical, electrical, thermal and mechanical stress the insulating material in the power transformer degraded. It is important to regularly assess the condition of oil and the remaining life of the power transformer. In this paper UV-VIS absorption graph area is correlated with moisture content, Flash point, IFT and Density of Transformer oil. Since UV-VIS absorption graph area varies accordingly with the variation in different transformer parameters. So by obtaining the correlation among different oil parameters for oil with respect to UV-VIS absorption area, decay contents of transformer oil can be predicted <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breakdown%20voltage%20%28BDV%29" title="breakdown voltage (BDV)">breakdown voltage (BDV)</a>, <a href="https://publications.waset.org/abstracts/search?q=interfacial%20Tension%20%28IFT%29" title=" interfacial Tension (IFT)"> interfacial Tension (IFT)</a>, <a href="https://publications.waset.org/abstracts/search?q=moisture%20content" title=" moisture content"> moisture content</a>, <a href="https://publications.waset.org/abstracts/search?q=ultra%20violet-visible%20rays%20spectroscopy%20%28UV-VIS%29" title=" ultra violet-visible rays spectroscopy (UV-VIS)"> ultra violet-visible rays spectroscopy (UV-VIS)</a> </p> <a href="https://publications.waset.org/abstracts/27975/ultraviolet-visible-spectroscopy-analysis-on-transformer-oil-by-correlating-it-with-various-oil-parameters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27975.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">642</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> Health Assessment of Power Transformer Using Fuzzy Logic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yog%20Raj%20Sood">Yog Raj Sood</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajnish%20Shrivastava"> Rajnish Shrivastava</a>, <a href="https://publications.waset.org/abstracts/search?q=Anchal%20Wadhwa"> Anchal Wadhwa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Power transformer is one of the electrical equipment that has a central and critical role in the power system. In order to avoid power transformer failure, information system that provides the transformer condition is needed. This paper presents an information system to know the exact situations prevailing within the transformer by declaring its health index. Health index of a transformer is decided by considering several diagnostic tools. The current work deals with UV-Vis, IFT, FP, BDV and Water Content. UV/VIS results have been pre-accessed using separate FL controller for concluding with the Furan contents. It is broadly accepted that the life of a power transformer is the life of the oil/ paper insulating system. The method relies on the use of furan analysis (insulation paper), and other oil analysis results as a means to declare health index. Fuzzy logic system is used to develop the information system. The testing is done on 5 samples of oil of transformers of rating 132/66 KV to obtain the results and results are analyzed using fuzzy logic model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interfacial%20tension%20analyzer%20%28ift%29" title="interfacial tension analyzer (ift)">interfacial tension analyzer (ift)</a>, <a href="https://publications.waset.org/abstracts/search?q=flash%20point%20%28fp%29" title=" flash point (fp)"> flash point (fp)</a>, <a href="https://publications.waset.org/abstracts/search?q=furfuraldehyde%20%28fal%29" title=" furfuraldehyde (fal)"> furfuraldehyde (fal)</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20index" title=" health index"> health index</a> </p> <a href="https://publications.waset.org/abstracts/27950/health-assessment-of-power-transformer-using-fuzzy-logic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27950.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">634</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Pawn or Potentates: Corporate Governance Structure in Indian Central Public Sector Enterprises</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ritika%20Jain">Ritika Jain</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajnish%20Kumar"> Rajnish Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Department of Public Enterprises had made submissions of Self Evaluation Reports, for the purpose of corporate governance, mandatory for all central government owned enterprises. Despite this, an alarming 40% of the enterprises did not do so. This study examines the impact of external policy tools and internal firm-specific factors on corporate governance of central public sector enterprises (CPSEs). We use a dataset of all manufacturing and non-financial services owned by the central government of India for the year 2010-11. Using probit, ordered logit and Heckman’s sample selection models, the study finds that the probability and quality of corporate governance is positively influenced by the CPSE getting into a Memorandum of Understanding (MoU) with the central government of India, and hence, enjoying more autonomy in terms of day to day operations. Besides these, internal factors, including bigger size and lower debt size contribute significantly to better corporate governance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corporate%20governance" title="corporate governance">corporate governance</a>, <a href="https://publications.waset.org/abstracts/search?q=central%20public%20sector%20enterprises%20%28CPSEs%29" title=" central public sector enterprises (CPSEs)"> central public sector enterprises (CPSEs)</a>, <a href="https://publications.waset.org/abstracts/search?q=sample%20selection" title=" sample selection"> sample selection</a>, <a href="https://publications.waset.org/abstracts/search?q=Memorandum%20of%20Understanding%20%28MoU%29" title=" Memorandum of Understanding (MoU)"> Memorandum of Understanding (MoU)</a>, <a href="https://publications.waset.org/abstracts/search?q=ordered%20logit" title=" ordered logit"> ordered logit</a>, <a href="https://publications.waset.org/abstracts/search?q=disinvestment" title=" disinvestment"> disinvestment</a> </p> <a href="https://publications.waset.org/abstracts/46842/pawn-or-potentates-corporate-governance-structure-in-indian-central-public-sector-enterprises" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46842.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">5</span> Beneficial Effect of Lupeol in Diabetes Induced Oxidative Damage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajnish%20Gupta">Rajnish Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=R.%20S.%20Gupta"> R.

Rats were divided into following groups mainly: control, diabetic, normal group as well as diabetic treated with Lupeol at 25 and 35 mg/kg b.wt./day for 21 days, diabetic group treated with glibenclamide. Tissue (pancreas, kidney and liver) as well as serum biochemical parameters were analysed for any abnormal behavior. Lupeol administration reduced diabetes onset with significant improvement in serum insulin level also strengthened by increase in β-Cell counts. A significant decrease was observed in serum glucose level. Furthermore, Lupeol treatment increased the antioxidant enzymes, glycolytic enzymes and also protein levels with a decrease in the level of thiobarbituric acid-reactive oxygen species and gluconeogenic enzymes. Present study proves that Lupeol administration significantly reinstated serum and tissue biochemical parameters and thus strengthening its antidiabetic potential. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title="oxidative stress">oxidative stress</a>, <a href="https://publications.waset.org/abstracts/search?q=pterostilbene" title=" pterostilbene"> pterostilbene</a>, <a href="https://publications.waset.org/abstracts/search?q=thiobarbituric%20acid" title=" thiobarbituric acid"> thiobarbituric acid</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20oxygen%20species" title=" reactive oxygen species"> reactive oxygen species</a> </p> <a href="https://publications.waset.org/abstracts/14774/beneficial-effect-of-lupeol-in-diabetes-induced-oxidative-damage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14774.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">470</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Statistical Tools for SFRA Diagnosis in Power Transformers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rahul%20Srivastava">Rahul Srivastava</a>, <a href="https://publications.waset.org/abstracts/search?q=Priti%20Pundir"> Priti Pundir</a>, <a href="https://publications.waset.org/abstracts/search?q=Y.%20R.%20Sood"> Y.

In this paper with the discussion on SFRA several statistics techniques like cross correlation coefficient (CCF), root square error (RSQ), comparative standard deviation (CSD), Absolute difference, mean square error(MSE),Min-Max ratio(MM) are presented through several case studies. These methods require sample data size and spot frequencies of SFRA signatures that are being compared. The techniques used are based on power signal processing tools that can simplify result and limits can be created for the severity of the fault occurring in the transformer due to several short circuit forces or due to ageing. The advantages of using statistics techniques for analyzing of SFRA result are being indicated through several case studies and hence the results are obtained which determines the state of the transformer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absolute%20difference%20%28DABS%29" title="absolute difference (DABS)">absolute difference (DABS)</a>, <a href="https://publications.waset.org/abstracts/search?q=cross%20correlation%20coefficient%20%28CCF%29" title=" cross correlation coefficient (CCF)"> cross correlation coefficient (CCF)</a>, <a href="https://publications.waset.org/abstracts/search?q=mean%20square%20error%20%28MSE%29" title=" mean square error (MSE)"> mean square error (MSE)</a>, <a href="https://publications.waset.org/abstracts/search?q=min-max%20ratio%20%28MM-ratio%29" title=" min-max ratio (MM-ratio)"> min-max ratio (MM-ratio)</a>, <a href="https://publications.waset.org/abstracts/search?q=root%20square%20error%20%28RSQ%29" title=" root square error (RSQ)"> root square error (RSQ)</a>, <a href="https://publications.waset.org/abstracts/search?q=standard%20deviation%20%28CSD%29" title=" standard deviation (CSD)"> standard deviation (CSD)</a>, <a href="https://publications.waset.org/abstracts/search?q=sweep%20frequency%20response%20analysis%20%28SFRA%29" title=" sweep frequency response analysis (SFRA)"> sweep frequency response analysis (SFRA)</a> </p> <a href="https://publications.waset.org/abstracts/27968/statistical-tools-for-sfra-diagnosis-in-power-transformers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27968.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">697</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Characterization of Mg/Sc System for X-Ray Spectroscopy in the Water Window Range</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hina%20Verma">Hina Verma</a>, <a href="https://publications.waset.org/abstracts/search?q=Karine%20Le%20Guen"> Karine Le Guen</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20H.%20Modi"> Mohammed H.

The water window range, located between the absorption edges of carbon (285 eV) and oxygen (530eV), along with the presence of nitrogen K absorption edge (395 eV), makes it a powerful method for imaging biological samples due to the natural optical contrast between water and carbon. We characterized bilayer, trilayer, quadrilayer, and multilayer systems of Mg/Sc with ZrC thin layers introduced as a barrier layer and capping layer prepared by ion beam sputtering. The introduction of ZrC as a barrier layer is expected to improve the structure of the Mg/Sc system. The ZrC capping layer also prevents the stack from oxidation. The structural analysis of the Mg/Sc systems was carried out by using grazing incidence X-ray reflectivity (GIXRR) to obtain non-destructively a first description of the structural parameters, thickness, roughness, and density of the layers. Resonant soft X-ray reflectivity measurements in the vicinity of Sc L-absorption edge were performed to investigate and quantify the atomic distribution of deposited layers. Near absorption edge, the atomic scattering factor of an element changes sharply depending on its chemical environment inside the structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buried%20interfaces" title="buried interfaces">buried interfaces</a>, <a href="https://publications.waset.org/abstracts/search?q=resonant%20soft%20X-ray%20reflectivity" title=" resonant soft X-ray reflectivity"> resonant soft X-ray reflectivity</a>, <a href="https://publications.waset.org/abstracts/search?q=X-ray%20optics" title=" X-ray optics"> X-ray optics</a>, <a href="https://publications.waset.org/abstracts/search?q=X-ray%20reflectivity" title=" X-ray reflectivity"> X-ray reflectivity</a> </p> <a href="https://publications.waset.org/abstracts/137075/characterization-of-mgsc-system-for-x-ray-spectroscopy-in-the-water-window-range" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137075.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">177</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Comparison of 18F-FDG and 11C-Methionine PET-CT for Assessment of Response to Neoadjuvant Chemotherapy in Locally Advanced Breast Carcinoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sonia%20Mahajan%20Dinesh">Sonia Mahajan Dinesh</a>, <a href="https://publications.waset.org/abstracts/search?q=Anant%20Dinesh"> Anant Dinesh</a>, <a href="https://publications.waset.org/abstracts/search?q=Madhavi%20Tripathi"> Madhavi Tripathi</a>, <a href="https://publications.waset.org/abstracts/search?q=Vinod%20Kumar%20Ramteke"> Vinod Kumar Ramteke</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajnish%20Sharma"> Rajnish Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Anupam%20Mondal"> Anupam Mondal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Neo-adjuvant chemotherapy plays an important role in treatment of breast cancer by decreasing the tumour load and it offers an opportunity to evaluate response of primary tumour to chemotherapy. Standard anatomical imaging modalities are unable to accurately reflect the response to chemotherapy until several cycles of drug treatment have been completed. Metabolic imaging using tracers like 18F-fluorodeoxyglucose (FDG) as a marker of glucose metabolism or amino acid tracers like L-methyl-11C methionine (MET) have potential role for the measurement of treatment response. In this study, our objective was to compare these two PET tracers for assessment of response to neoadjuvant chemotherapy, in locally advanced breast carcinoma. Methods: In our prospective study, 20 female patients with histology proven locally advanced breast carcinoma underwent PET-CT imaging using FDG and MET before and after three cycles of neoadjuvant chemotherapy (CAF regimen). Thereafter, all patients were taken for MRM and the resected specimen was sent for histo-pathological analysis. Tumour response to the neoadjuvant chemotherapy was evaluated by PET-CT imaging using PERCIST criteria and correlated with histological results. Responses calculated were compared for statistical significance using paired t- test. Results: Mean SUVmax for primary lesion in FDG PET and MET PET was 15.88±11.12 and 5.01±2.14 respectively (p<0.001) and for axillary lymph nodes was 7.61±7.31 and 2.75±2.27 respectively (p=0.001). Statistically significant response in primary tumour and axilla was noted on both FDG and MET PET after three cycles of NAC. Complete response in primary tumour was seen in only 1 patient in FDG and 7 patients in MET PET (p=0.001) whereas there was no histological complete resolution of tumor in any patient. Response to therapy in axillary nodes noted on both PET scans were similar (p=0.45) and correlated well with histological findings. Conclusions: For the primary breast tumour, FDG PET has a higher sensitivity and accuracy than MET PET and for axilla both have comparable sensitivity and specificity. FDG PET shows higher target to background ratios so response is better predicted for primary breast tumour and axilla. Also, FDG-PET is widely available and has the advantage of a whole body evaluation in one study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=11C-methionine" title="11C-methionine">11C-methionine</a>, <a href="https://publications.waset.org/abstracts/search?q=18F-FDG" title=" 18F-FDG"> 18F-FDG</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20carcinoma" title=" breast carcinoma"> breast carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=neoadjuvant%20chemotherapy" title=" neoadjuvant chemotherapy"> neoadjuvant chemotherapy</a> </p> <a href="https://publications.waset.org/abstracts/1987/comparison-of-18f-fdg-and-11c-methionine-pet-ct-for-assessment-of-response-to-neoadjuvant-chemotherapy-in-locally-advanced-breast-carcinoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1987.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">510</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Investigation of Chemical Effects on the Lγ2,3 and Lγ4 X-ray Production Cross Sections for Some Compounds of 66dy at Photon Energies Close to L1 Absorption-edge Energy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anil%20Kumar">Anil Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajnish%20Kaur"> Rajnish Kaur</a>, <a href="https://publications.waset.org/abstracts/search?q=Mateusz%20Czyzycki"> Mateusz Czyzycki</a>, <a href="https://publications.waset.org/abstracts/search?q=Alessandro%20Migilori"> Alessandro Migilori</a>, <a href="https://publications.waset.org/abstracts/search?q=Andreas%20Germanos%20Karydas"> Andreas Germanos Karydas</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjiv%20Puri"> Sanjiv Puri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The radiative decay of Li(i=1-3) sub-shell vacancies produced through photoionization results in production of the characteristic emission spectrum comprising several X-ray lines, whereas non-radiative vacancy decay results in Auger electron spectrum. Accurate reliable data on the Li(i=1-3) sub-shell X-ray production (XRP) cross sections is of considerable importance for investigation of atomic inner-shell ionization processes as well as for quantitative elemental analysis of different types of samples employing the energy dispersive X-ray fluorescence (EDXRF) analysis technique. At incident photon energies in vicinity of the absorption edge energies of an element, the many body effects including the electron correlation, core relaxation, inter-channel coupling and post-collision interactions become significant in the photoionization of atomic inner-shells. Further, in case of compounds, the characteristic emission spectrum of the specific element is expected to get influenced by the chemical environment (coordination number, oxidation state, nature of ligand/functional groups attached to central atom, etc.). These chemical effects on L X-ray fluorescence parameters have been investigated by performing the measurements at incident photon energies much higher than the Li(i=1-3) sub-shell absorption edge energies using EDXRF spectrometers. In the present work, the cross sections for production of the Lk(k= γ2,3, γ4) X-rays have been measured for some compounds of 66Dy, namely, Dy2O3, Dy2(CO3)3, Dy2(SO4)3.8H2O, DyI2 and Dy metal by tuning the incident photon energies few eV above the L1 absorption-edge energy in order to investigate the influence of chemical effects on these cross sections in presence of the many body effects which become significant at photon energies close to the absorption-edge energies. The present measurements have been performed under vacuum at the IAEA end-station of the X-ray fluorescence beam line (10.1L) of ELETTRA synchrotron radiation facility (Trieste, Italy) using self-supporting pressed pellet targets (1.3 cm diameter, nominal thicknesses ~ 176 mg/cm2) of 66Dy compounds (procured from Sigma Aldrich) and a metallic foil of 66Dy (nominal thickness ~ 3.9 mg/cm2, procured from Good Fellow, UK). The present measured cross sections have been compared with theoretical values calculated using the Dirac-Hartree-Slater(DHS) model based fluorescence and Coster-Kronig yields, Dirac-Fock(DF) model based X-ray emission rates and two sets of L1 sub-shell photoionization cross sections based on the non-relativistic Hartree-Fock-Slater(HFS) model and those deduced from the self-consistent Dirac-Hartree-Fock(DHF) model based total photoionization cross sections. The present measured XRP cross sections for 66Dy as well as for its compounds for the L2,3 and L4 X-rays, are found to be higher by ~14-36% than the two calculated set values. It is worth to be mentioned that L2,3 and L4 X-ray lines are originated by filling up of the L1 sub-shell vacancies by the outer sub-shell (N2,3 and O2,3) electrons which are much more sensitive to the chemical environment around the central atom. The present observed differences between measured and theoretical values are expected due to combined influence of the many-body effects and the chemical effects. <p
