cell devices. Lead-based perovskites are among the most promising materials, but their application is plagued with toxicity and stability concerns. Most of the perovskite solar cell consists of conventional (n-i-p) structure with organic or inorganic charge transport materials. The commercial application of such device is limited due to higher J-V hysteresis and the need for high temperature during fabrication. This numerical analysis primarily directs to investigate the performance of various inorganic lead-free valency ordered double perovskite absorber materials and to develop an inverted perovskite solar cell device structure. Simulation efforts using SCAPS-1D was carried out with various organic and inorganic charge transport materials with absorber layer materials, and their performance has been evaluated for various factors of thickness, absorber thickness, absorber defect density, and interface defect density to achieve the optimized structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=perovskite%20materials" title="perovskite materials">perovskite materials</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20cell" title=" solar cell"> solar cell</a>, <a href="https://publications.waset.org/abstracts/search?q=inverted%20solar%20cell" title=" inverted solar cell"> inverted solar cell</a>, <a href="https://publications.waset.org/abstracts/search?q=inorganic%20perovskite%20solar%20cell%20materials" title=" inorganic perovskite solar cell materials"> inorganic perovskite solar cell materials</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20efficiency" title=" cell efficiency"> cell efficiency</a> </p> <a href="https://publications.waset.org/abstracts/166962/device-modelling-and-analysis-of-eco-friendly-inverted-solar-cell-structure-using-valency-ordered-inorganic-double-perovskite-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166962.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">83</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">70</span> FTIR Characterization of EPS Ligands from Mercury Resistant Bacterial Isolate, Paenibacillus jamilae PKR1</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Debajit%20Kalita">Debajit Kalita</a>, <a href="https://publications.waset.org/abstracts/search?q=Macmillan%20Nongkhlaw"> Macmillan Nongkhlaw</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20R.%20Joshi"> S.

Exposure to mercury is known to affect the nervous, gastrointestinal and renal systems. In the present study, a bacterial isolate identified using 16S rRNA marker as Paenibacillus jamilae PKR1 isolated from India’s largest sandstone-type uranium deposits, containing an average of 0.1% U3O8, was found to be resistance to Hg contamination under culture conditions. It showed strong hydrophobicity as revealed by SAT, MATH, PAT, SAA adherence assays. The Fourier Transform Infrared (FTIR) spectra showed the presence of hydroxyl, amino and carboxylic functional groups on the cell surface EPS which are known to contribute in the binding of metals. It is proposed that the characterized isolate tolerating up to 4.0mM of mercury provides scope for its application in bioremediation of mercury from contaminated sites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mercury" title="mercury">mercury</a>, <a href="https://publications.waset.org/abstracts/search?q=Domiasiat" title=" Domiasiat"> Domiasiat</a>, <a href="https://publications.waset.org/abstracts/search?q=uranium" title=" uranium"> uranium</a>, <a href="https://publications.waset.org/abstracts/search?q=paenibacillus%20jamilae" title=" paenibacillus jamilae"> paenibacillus jamilae</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrophobicity" title=" hydrophobicity"> hydrophobicity</a>, <a href="https://publications.waset.org/abstracts/search?q=FTIR" title=" FTIR"> FTIR</a> </p> <a href="https://publications.waset.org/abstracts/31677/ftir-characterization-of-eps-ligands-from-mercury-resistant-bacterial-isolate-paenibacillus-jamilae-pkr1" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31677.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">409</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">69</span> Actinomycetes from Protected Forest Ecosystems of Assam, India: Diversity and Antagonistic Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Priyanka%20Sharma">Priyanka Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Ranjita%20Das"> Ranjita Das</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohan%20C.%20Kalita"> Mohan C.

The present study aims at the antimicrobial potential and genetic diversity of culturable Actinomycetes isolated from protected forest ecosystems of Assam which includes Kaziranga National Park (26°30˝-26°45˝N and 93°08˝-93°36˝E), Pobitora Wildlife Sanctuary (26º12˝-26º16˝N and 91º58˝-92º05˝E) and Gibbon Wildlife Sanctuary (26˚40˝-26˚45˝N and 94˚20˝-94˚25˝E) which are located in the North-eastern part of India. Northeast India is a part of the Indo-Burma mega biodiversity hotspot and most of the protected forests of this region are still unexplored for the isolation of effective antibiotic-producing Actinomycetes. Thus, there is tremendous possibility that these virgin forests could be a potential storehouse of novel microorganisms, particularly Actinomycetes, exhibiting diverse biological properties. Methodology: Soil samples were collected from different ecological niches of the protected forest ecosystems of Assam and Actinomycetes were isolated by serial dilution spread plate technique using five selective isolation media. Preliminary screening of Actinomycetes for an antimicrobial activity was done by spot inoculation method and the secondary screening by disc diffusion method against several test pathogens, including multidrug resistant Staphylococcus aureus (MRSA). The strains were further screened for the presence of antibiotic synthetic genes such as type I polyketide synthases (PKS-I), type II polyketide synthases (PKS-II) and non-ribosomal peptide synthetases (NRPS) genes. Genetic diversity of the Actinomycetes producing antimicrobial metabolites was analyzed through 16S rDNA-RFLP using Hinf1 restriction endonuclease. Results: Based on the phenotypic characterization, a total of 172 morphologically distinct Actinomycetes were isolated and screened for antimicrobial activity by spot inoculation method on agar medium. Among the strains tested, 102 (59.3%) strains showed activity against Gram-positive bacteria, 98 (56.97%) against Gram-negative bacteria, 92 (53.48%) against Candida albicans MTCC 227 and 130 (75.58%) strains showed activity against at least one of the test pathogens. Twelve Actinomycetes exhibited broad spectrum antimicrobial activity in the secondary screening. The taxonomic identification of these twelve strains by 16S rDNA sequencing revealed that Streptomyces was found to be the predominant genus. The PKS-I, PKS-II and NRPS genes detection indicated diverse bioactive products of these twelve Actinomycetes. Genetic diversity by 16S rDNA-RFLP indicated that Streptomyces was the dominant genus amongst the antimicrobial metabolite producing Actinomycetes. Conclusion: These findings imply that Actinomycetes from the protected forest ecosystems of Assam, India, are a potential source of bioactive secondary metabolites. These areas are as yet poorly studied and represent diverse and largely unscreened ecosystem for the isolation of potent Actinomycetes producing antimicrobial secondary metabolites. Detailed characterization of the bioactive Actinomycetes as well as purification and structure elucidation of the bioactive compounds from the potent Actinomycetes is the subject of ongoing investigation. Thus, to exploit Actinomycetes from such unexplored forest ecosystems is a way to develop bioactive products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Actinomycetes" title="Actinomycetes">Actinomycetes</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20activity" title=" antimicrobial activity"> antimicrobial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=forest%20ecosystems" title=" forest ecosystems"> forest ecosystems</a>, <a href="https://publications.waset.org/abstracts/search?q=RFLP" title=" RFLP"> RFLP</a> </p> <a href="https://publications.waset.org/abstracts/31375/actinomycetes-from-protected-forest-ecosystems-of-assam-india-diversity-and-antagonistic-activity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31375.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">391</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">68</span> Ways of Innovative Sustainable Agriculture in India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shailja%20Thakur">Shailja Thakur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper it is shown that how farmers are suffering from all sides including vagaries of weather then price fluctuations, demand supply constraints, poor soil health etc. Also the ICT can prove to be of great help if incorporated rightly into Indian agriculture.

With increasing Cu loading, pronounced and progressive red shifts of the C–O stretching frequency associated with molecular CO adsorbed on the Cu/SnO2 component were observed. This decrease in n(CO) correlates with enhancement of CO dissociation at higher temperatures on Cu promoted SnO2 catalysts under conditions, where clean Cu is almost ineffective.

In this work effect of sedimentation on torque transmission in the shear mode operated MR clutch is investigated. A test rig is developed to test the impact of sedimentation on torque transmission in the MR clutch. Torque transmission capability of MR clutch has been measured under two conditions to confirm the result of sedimentation. The first experiment is done just after filling and the other after one week. It has been observed that transmission torque is decreased after sedimentation.

From the results, it could be seen that for K<0, high pressure is required in the initial yielding state than for the case K >0. Under thermal conditions for value K<0, lesser amount of pressure is required for initial yielding, and further, the amount keeps on decreasing with an increase in temperature. Curves are drawn between pressure and radii ratio for initial and fully plastic state with and without temperature conditions. Further graphs between stresses (hoop and radial) and radii ratio for fully plastic state with and without temperature conditions are also drawn and concluded that hoop stresses become minimum with the increase in temperature as compared to radial stresses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cylinder" title="cylinder">cylinder</a>, <a href="https://publications.waset.org/abstracts/search?q=elastic" title=" elastic"> elastic</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic" title=" plastic"> plastic</a>, <a href="https://publications.waset.org/abstracts/search?q=copper" title=" copper"> copper</a>, <a href="https://publications.waset.org/abstracts/search?q=steel" title=" steel"> steel</a>, <a href="https://publications.waset.org/abstracts/search?q=stresses" title=" stresses"> stresses</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure" title=" pressure"> pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=load" title=" load"> load</a> </p> <a href="https://publications.waset.org/abstracts/160926/non-homogeneity-in-a-thick-walled-rotating-circular-cylinder-under-varying-pressure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160926.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">81</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">58</span> Antımıcrobıal Actıvıty of Gırardınıa Heterophılla</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20S.%20BEDI%2A">P.

The designed filter has been synthesized on DSP slice based FPGA to perform multiplier function of MAC unit. The DSP slices are useful to enhance the speed performance. The developed IIR filter is designed and simulated with Matlab and synthesized with Xilinx Synthesis Tool (XST), and implemented on Virtex 5 and Spartan 3 ADSP FPGA devices. The IIR filter implemented on Virtex 5 FPGA can operate at an estimated frequency of 81.5 MHz as compared to 40.5 MHz in case of Spartan 3 ADSP FPGA. The Virtex 5 based implementation also consumes less slices and slice flip flops of target FPGA in comparison to Spartan 3 ADSP based implementation to provide cost effective solution for signal processing applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Butterworth%20filter" title="Butterworth filter">Butterworth filter</a>, <a href="https://publications.waset.org/abstracts/search?q=DSP" title=" DSP"> DSP</a>, <a href="https://publications.waset.org/abstracts/search?q=IIR" title=" IIR"> IIR</a>, <a href="https://publications.waset.org/abstracts/search?q=MAC" title=" MAC"> MAC</a>, <a href="https://publications.waset.org/abstracts/search?q=FPGA" title=" FPGA"> FPGA</a> </p> <a href="https://publications.waset.org/abstracts/41409/fpga-based-iir-filter-design-using-mac-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41409.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">388</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">56</span> The Optimization of Immobilization Conditions for Biohydrogen Production from Palm Industry Wastewater</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20W.%20Zularisam">A.

LS2 was immobilised by entrapment in polyethylene glycol (PEG) gel beads to improve the biohydrogen production rate from palm oil mill effluent (POME). We sought to explore and optimise the hydrogen production capability of the immobilised cells by studying the conditions for cell immobilisation, including PEG concentration, cell loading and curing times, as well as the effects of temperature and K2HPO4 (500–2000 mg/L), NiCl2 (0.1–5.0 mg/L), FeCl2 (100–400 mg/L) MgSO4 (50–200 mg/L) concentrations on hydrogen production rate. The results showed that by optimising the PEG concentration (10% w/v), initial biomass (2.2 g dry weight), curing time (80 min) and temperature (37 °C), as well as the concentrations of K2HPO4 (2000 mg/L), NiCl2 (1 mg/L), FeCl2 (300 mg/L) and MgSO4 (100 mg/L), a maximum hydrogen production rate of 7.3 L/L-POME/day and a yield of 0.31 L H2/g chemical oxygen demand were obtained during continuous operation.

It is very important to decipher these fingerprints in order to explore their identity and a lot of research has been made on the visualization of latent fingermarks on various substrates by numerous researchers. During the past few years large number of powder formulations has been evolved for the development of latent fingermarks on different surfaces. This paper reports a new and simple fingerprint powder which is non-toxic and has been employed on different substrates successfully for the development and visualization of latent fingermarks upto the time period of twelve days in varying temperature conditions. In this study, a less expensive, simple and easily available catechu (kattha) powder has been used to decipher the latent fingermarks on different substrates namely glass, plastic, metal, aluminium foil, white paper, wall tile and wooden sheet. It is observed that it gives very clear results on all the mentioned substrates and can be successfully used for the development and visualization of twelve days old latent fingermarks in varying temperature conditions on wall tiles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fingermarks" title="fingermarks">fingermarks</a>, <a href="https://publications.waset.org/abstracts/search?q=catechu" title=" catechu"> catechu</a>, <a href="https://publications.waset.org/abstracts/search?q=visualization" title=" visualization"> visualization</a>, <a href="https://publications.waset.org/abstracts/search?q=aged%20fingermarks" title=" aged fingermarks"> aged fingermarks</a> </p> <a href="https://publications.waset.org/abstracts/84923/herbal-based-fingerprint-powder-formulation-for-latent-fingermark-visualization-catechu-kattha" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84923.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">188</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">54</span> Anti-Oxidant and Anti-Bacterial Properties of Camellia sinensis, Tea Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rini%20Jarial">Rini Jarial</a>, <a href="https://publications.waset.org/abstracts/search?q=Puranjan%20Mishra"> Puranjan Mishra</a>, <a href="https://publications.waset.org/abstracts/search?q=Lakhveer%20Singh"> Lakhveer Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sveta%20Thakur"> Sveta Thakur</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20W.%20Zularisam"> A.

The methanolic leaves-extract (MLE) of commercial green tea (Camellia sinensis) was assessed for anti-bacterial activities by measuring inhibition zones against a panel of pathogenic bacterial strains using agar diffusion method. The flavonoid (5.0 to 8.0 mg/ml) and protein content (10 to 15 mg/ml) of the MLE were recorded. MLE at a concentration of 25 μg/ml showed marked anti-bacterial activity against all bacterial strains (11-30 mm zone of inhibition) and was maximum against Staphylococcus aureus (30 mm). The MLE of Camellia sinensis had the best MIC values of 2.25 and 0.56 mg/ml against S. aureus and Enterobacter sp., respectively. The MLE also possessed good anti-lipolytic activity (65%) against a Porcine pancreatic lipase (PPL) and cholesterol oxidase inhibition (79%). The present study provided strong experimental evidences that the MLE of Camellia sinensis is not only a potent source of natural anti-oxidants and anti-bacterial activity but also possesses efficient cholesterol degradation and anti-lipolytic activities that might be beneficial in the body weight management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-oxidant" title="anti-oxidant">anti-oxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-bacterial%20activity" title=" anti-bacterial activity"> anti-bacterial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-lipolytic%20activity" title=" anti-lipolytic activity"> anti-lipolytic activity</a>, <a href="https://publications.waset.org/abstracts/search?q=Camellia%20sinensis" title=" Camellia sinensis"> Camellia sinensis</a>, <a href="https://publications.waset.org/abstracts/search?q=phyto-chemicals" title=" phyto-chemicals"> phyto-chemicals</a> </p> <a href="https://publications.waset.org/abstracts/46770/anti-oxidant-and-anti-bacterial-properties-of-camellia-sinensis-tea-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46770.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">291</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">53</span> Spectrum Allocation in Cognitive Radio Using Monarch Butterfly Optimization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Avantika%20Vats">Avantika Vats</a>, <a href="https://publications.waset.org/abstracts/search?q=Kushal%20Thakur"> Kushal Thakur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper displays the point at issue, improvement, and utilization of a Monarch Butterfly Optimization (MBO) rather than a Genetic Algorithm (GA) in cognitive radio for the channel portion. This approach offers a satisfactory approach to get the accessible range of both the users, i.e., primary users (PUs) and secondary users (SUs). The proposed enhancement procedure depends on a nature-inspired metaheuristic algorithm. In MBO, all the monarch butterfly individuals are located in two distinct lands, viz. Southern Canada and the northern USA (land 1), and Mexico (Land 2). The positions of the monarch butterflies are modernizing in two ways. At first, the offsprings are generated (position updating) by the migration operator and can be adjusted by the migration ratio. It is trailed by tuning the positions for different butterﬂies by the methods for the butterfly adjusting operator. To keep the population unaltered and minimize fitness evaluations, the aggregate of the recently produced butterﬂies in these two ways stays equivalent to the first population.

The experimental material consisted of carry over wheat seeds (variety HPW- 155) of rabi 2017 - 18. The observations were recorded bimonthly on parameters viz; germination (%), seedling length (cm), dry weight (g), vigour index - I, vigour - II, speed of germination, field emergence (%), 100 seed weight (g) for 12 months of storage. All parameters declined with the advancement in storage period. The results showed that seeds treated with polymer + vitavax 200 @ 2 g/kg of seed recorded higher germination percentage (95.00 %), seedling length (17.58 cm), seedling dry weight (0.0138 g), vigour index - I (1670) & vigour - II (1.311), speed of germination (19.98), 100 seed weight (5.54 g) and field emergence (87.33 %) which was at par with vitavax 200 @ 2 g/kg of seed, over untreated control (T1). So it can be concluded that for maintain seed quality and enhancing storability, seed of wheat can either be treated with polymer @ 3 ml/kg of seed + vitavax 200 @ 2 g/kg of seed or vitavax 200 @ 2 g/kg of seed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wheat" title="wheat">wheat</a>, <a href="https://publications.waset.org/abstracts/search?q=seed%20treatment" title=" seed treatment"> seed treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=storability" title=" storability"> storability</a>, <a href="https://publications.waset.org/abstracts/search?q=seed%20quality" title=" seed quality"> seed quality</a> </p> <a href="https://publications.waset.org/abstracts/137370/effect-of-seed-treatment-on-seed-quality-and-storability-in-wheat-triticum-aestivum-l-in-northwestern-himalayas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137370.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">172</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">48</span> Identification and Characterization of 18S rRNA Gene of Demodex Canis From the Dog Population of Mizoram, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Moneesh%20Thakur">Moneesh Thakur</a>, <a href="https://publications.waset.org/abstracts/search?q=Hridayesh%20Prasad"> Hridayesh Prasad</a>, <a href="https://publications.waset.org/abstracts/search?q=Nikitasha%20Bora"> Nikitasha Bora</a>, <a href="https://publications.waset.org/abstracts/search?q=Parimal%20Roy%20Choudhary"> Parimal Roy Choudhary</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20K.%20Samanta"> A.

Canine demodicosis can occur as either a localized or generalized form of demodicosis severely affect the dogs and in non-treated dogs may cause death. This study was planned with the aim to screen and characterize the 18S rRNA gene of isolated Demodex canis. A total of 1200 dogs were screened during this study period. The skin scrapings of all the suspected dogs were examined under a microscope at 100X magnification for the presence of Demodex canis. The skin scrapings positive for Demodex canis were examined using PCR for confirmation. A total of 35 dogs were confirmed a positive result for D. canis based on 18S rRNA gene amplification by PCR. Further, the 18S rRNA gene of isolated Demodex canis was cloned and sequenced for genome analysis. On the sequence analysis, it was found that isolated sequence (GenBank Accession No. MK177513) had close similarity (99.7%) to that of D. canis genotype of China (Accession No. MG372254). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PCR" title="PCR">PCR</a>, <a href="https://publications.waset.org/abstracts/search?q=phylogenetic%20analysis" title=" phylogenetic analysis"> phylogenetic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=cloning%20and%20sequening" title=" cloning and sequening"> cloning and sequening</a>, <a href="https://publications.waset.org/abstracts/search?q=Demodex%20canis" title=" Demodex canis"> Demodex canis</a> </p> <a href="https://publications.waset.org/abstracts/172036/identification-and-characterization-of-18s-rrna-gene-of-demodex-canis-from-the-dog-population-of-mizoram-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172036.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">92</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">47</span> Escaping the Trauma: A Psychological Study of Jonathan Safran Foer’s Extremely Loud & Incredibly Close</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahima%20Thakur">Mahima Thakur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Trauma rehabilitation requires both repairing physical injury and reconstructing broken narrative systems. The trauma's aftereffects entwine the broken patterns, allowing a cohesive narrative to emerge. In this article, the book Extremely Loud and Incredibly Close by Jonathan Safran Foer is discussed from a psychoanalytic perspective. The paper discusses the 9/11 attacks and their effects on those who suffered and lost family members during the catastrophe. The primary character of the novel, Oskar, along with his grandfather and grandmother, each have unique trauma escape stories that will be examined in light of Cathy Caruth and Geoffery H. Hartman‘s study. The text's numerous horrifying repetitions function as a narration strategy that not only captures the awareness of trauma but also gives the reader the psychological feature to overcome its deadening effects. This article explores the role that communication may have in assisting individuals in overcoming trauma. In addition to more research on traumatic memories, Dominick LaCapra's trauma theory's notions of "working through" and "acting out" highlight the need of communication in overcoming trauma and attempting to live outside of it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=trauma%20theory" title="trauma theory">trauma theory</a>, <a href="https://publications.waset.org/abstracts/search?q=Cathy%20Caruth" title=" Cathy Caruth"> Cathy Caruth</a>, <a href="https://publications.waset.org/abstracts/search?q=memories" title=" memories"> memories</a>, <a href="https://publications.waset.org/abstracts/search?q=escapes" title=" escapes"> escapes</a>, <a href="https://publications.waset.org/abstracts/search?q=communication" title=" communication"> communication</a> </p> <a href="https://publications.waset.org/abstracts/191897/escaping-the-trauma-a-psychological-study-of-jonathan-safran-foers-extremely-loud-incredibly-close" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191897.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">21</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">46</span> Climate Change Impacts on Oyster Aquaculture - Part I: Identification of Key Factors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Okine%20Neokye">Emmanuel Okine Neokye</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiuquan%20Wang"> Xiuquan Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Krishna%20K.%20Thakur"> Krishna K.

The production of oysters plays an important role in the local economies of coastal communities in many countries, including Atlantic Canada, because of their high economic value. However, because of the changing climatic conditions in recent years, oyster aquaculture faces potentially negative impacts, such as increasing water acidification, rising water temperatures, high salinity, invasive species, algal blooms, and other environmental factors. Although a few isolated effects of climate change on oyster aquaculture have been reported in recent years, it is not well understood how climate change will affect oyster aquaculture from a systematic perspective. In the first part of this study, we present a systematic review of the impacts of climate change and some key environmental factors affecting oyster production on a global scale. The study also identifies knowledge gaps and challenges. In addition, we present key research directions that will facilitate future investigations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=oyster%20production" title=" oyster production"> oyster production</a>, <a href="https://publications.waset.org/abstracts/search?q=oyster%20aquaculture" title=" oyster aquaculture"> oyster aquaculture</a>, <a href="https://publications.waset.org/abstracts/search?q=greenhouse%20gases" title=" greenhouse gases"> greenhouse gases</a> </p> <a href="https://publications.waset.org/abstracts/193178/climate-change-impacts-on-oyster-aquaculture-part-i-identification-of-key-factors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193178.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">13</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">45</span> Excitation Dependent Luminescence in Cr³+ Doped MgAl₂O₄ Nanocrystals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Savita">Savita</a>, <a href="https://publications.waset.org/abstracts/search?q=Pargam%20Vashishtha"> Pargam Vashishtha</a>, <a href="https://publications.waset.org/abstracts/search?q=Govind%20Gupta"> Govind Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Ankush%20Vij"> Ankush Vij</a>, <a href="https://publications.waset.org/abstracts/search?q=Anup%20Thakur"> Anup Thakur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ligand field dependent visible as well as NIR emission of the Cr³+dopant in spinel hosts has attracted immense attention in tuning the color emitted by the material. In this research, Mg1-xCrxAl₂O₄(x=0.5, 1, 3, 5, and 10 mol%) nanocrystals have been synthesizedby solution combustion method. The synthesized nanocrystals possessed a single phase cubic structure. The strong absorption by host lattice defects (antisite defects, F centres) andd-d transitions of Cr³+ ions lead to radiative emission in the visible and NIR region, respectively. The red-NIR emission in photoluminescence spectra inferred the octahedral symmetry of Cr³+ ions and anticipated the site distortion by the presence ofCr³+ clusters and antisite defects in the vicinity of Cr³+ ions. The thermoluminescence response of UV and γ-irradiated Cr doped MgAl2O4 samples revealed the formation of various shallow and deep defects with doping Cr³+ions. The induced structural cation disorder with an increase in doping concentration caused photoluminescence quenching beyond 3 mol% Cr³+ doping. The color tuning exhibited by Cr doped MgAl₂O₄ nanocrystals by varying Cr³+ ion concentration and excitation wavelength find its applicability in solid state lighting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antisite%20defects" title="antisite defects">antisite defects</a>, <a href="https://publications.waset.org/abstracts/search?q=cation%20disorder" title=" cation disorder"> cation disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=color%20tuning" title=" color tuning"> color tuning</a>, <a href="https://publications.waset.org/abstracts/search?q=combustion%20synthesis" title=" combustion synthesis"> combustion synthesis</a> </p> <a href="https://publications.waset.org/abstracts/139110/excitation-dependent-luminescence-in-cr3-doped-mgal2o4-nanocrystals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139110.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">178</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">44</span> Climate Change and the Invasive Alien Species of Western Himalayan State of India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yashasvi%20Thakur">Yashasvi Thakur</a>, <a href="https://publications.waset.org/abstracts/search?q=Vikas%20K.%20Sharma"> Vikas K.

A total of 297 naturalized alien plant species belonging to 65 families in the IHR have already been reported. Of the total 297 naturalized alien plant species in IHR, the maximum species occur in Himachal Pradesh (232; 78.1%), followed by Jammu & Kashmir (192; 64.6%) and Uttarakhand (181; 60.90%). The present study reports the spread of some invasive and existing weed species like Ageratum conyzoides, Bidens pilosa, Chromolaena odorata, Lantana camara, Brossnetia papyrifera, Oxalis corniculata, Galinsoga parviflora, Panicum maximum at an extent that they are not only invading the agricultural fields but are also replacing the native plant species and degrading the existing grassland quality. Moreover, the degradation of grassland has led to the dry fodder shortage for livestock in the lower Shivalik ranges of the state of Himachal Pradesh and has also encouraged the use of herbicides at an extensive scale. This article provides a mapping of the current spread of some of these species at the block level to allow the development of appropriate management strategies and policy planning for addressing issues pertaining to plant invasion, agricultural fields, and grasslands across the IHR states. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=invasive%20alien%20species" title=" invasive alien species"> invasive alien species</a>, <a href="https://publications.waset.org/abstracts/search?q=agriculture" title=" agriculture"> agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=grassland" title=" grassland"> grassland</a>, <a href="https://publications.waset.org/abstracts/search?q=IHR" title=" IHR"> IHR</a> </p> <a href="https://publications.waset.org/abstracts/174947/climate-change-and-the-invasive-alien-species-of-western-himalayan-state-of-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174947.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">74</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">43</span> Synthesis of Green Silver Nanoparticles with Aqueous Extract of Glycyrrhiza glabra and Its Characterization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mandeep%20Kataria">Mandeep Kataria</a>, <a href="https://publications.waset.org/abstracts/search?q=Ankita%20Thakur"> Ankita Thakur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Glycyrrhiza glabra grows in the sub- tropical and warm temperate regions of the world, in Mediterranean countries and China, America, Europe, Asia and Australia.

These Green Silver nanoparticles have been appropriately characterized using Visible spectroscopy, colour change. The Antimicrobial activity was done by Agar disc diffusion assay. AgNPs were developed by using aqueous root extract of Glycyrrhiza glabra, which acts as a reducing as well as stabilizing agent. The green synthetic method is a fast, low cost and eco-friendly process in the field of nanotechnology. The study revealed that the green-synthesized silver nanoparticle provides a promising approach for antimicrobial activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Glycyrrhiza%20glabra" title="Glycyrrhiza glabra">Glycyrrhiza glabra</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title=" nanoparticles"> nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20activity" title=" antimicrobial activity"> antimicrobial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=aqueous%20extract" title=" aqueous extract"> aqueous extract</a> </p> <a href="https://publications.waset.org/abstracts/102299/synthesis-of-green-silver-nanoparticles-with-aqueous-extract-of-glycyrrhiza-glabra-and-its-characterization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102299.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">128</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">42</span> Modeling and Analysis of DFIG Based Wind Power System Using Instantaneous Power Components</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaimala%20Ghambir">Jaimala Ghambir</a>, <a href="https://publications.waset.org/abstracts/search?q=Tilak%20Thakur"> Tilak Thakur</a>, <a href="https://publications.waset.org/abstracts/search?q=Puneet%20Chawla"> Puneet Chawla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As per the statistical data, the Doubly-fed Induction Generator (DFIG) based wind turbine with variable speed and variable pitch control is the most common wind turbine in the growing wind market. This machine is usually used on the grid connected wind energy conversion system to satisfy grid code requirements such as grid stability, fault ride through (FRT), power quality improvement, grid synchronization and power control etc. Though the requirements are not fulfilled directly by the machine, the control strategy is used in both the stator as well as rotor side along with power electronic converters to fulfil the requirements stated above. To satisfy the grid code requirements of wind turbine, usually grid side converter is playing a major role. So in order to improve the operation capacity of wind turbine under critical situation, the intensive study of both machine side converter control and grid side converter control is necessary In this paper DFIG is modeled using power components as variables and the performance of the DFIG system is analysed under grid voltage fluctuations. The voltage fluctuations are made by lowering and raising the voltage values in the utility grid intentionally for the purpose of simulation keeping in view of different grid disturbances. <p
