The e-commerce transaction processes are made up of a variety of diverse organizations and activities that operate independently but are connected together to complete the transaction (from placing an order to the goods reaching the client). After a negative shopping experience, clients frequently disregard the critical assessment of these businesses and submit their feedback on an all-over basis, which benefits certain enterprises but is tedious for others. In this article, we solely dealt with negative reviews and attempted to distinguish between negative reviews where the e-commerce firm is explicitly blamed by customers for a bad purchasing experience and other negative reviews. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=e-commerce" title="e-commerce">e-commerce</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20shopping" title=" online shopping"> online shopping</a>, <a href="https://publications.waset.org/abstracts/search?q=customer%20reviews" title=" customer reviews"> customer reviews</a>, <a href="https://publications.waset.org/abstracts/search?q=customer%20behaviour" title=" customer behaviour"> customer behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=text%20analytics" title=" text analytics"> text analytics</a>, <a href="https://publications.waset.org/abstracts/search?q=n-grams%20classification" title=" n-grams classification"> n-grams classification</a> </p> <a href="https://publications.waset.org/abstracts/168088/blame-classification-through-n-grams-in-e-commerce-customer-reviews" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168088.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">49</span> Estimation of the Mean of the Selected Population</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kalu%20Ram%20Meena">Kalu Ram Meena</a>, <a href="https://publications.waset.org/abstracts/search?q=Aditi%20Kar%20Gangopadhyay"> Aditi Kar Gangopadhyay</a>, <a href="https://publications.waset.org/abstracts/search?q=Satrajit%20Mandal"> Satrajit Mandal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Two normal populations with different means and same variance are considered, where the variances are known.

Corrosion in rebars causes cracking in concrete which can lead to the change in properties of beam. In the present study, two RC beams with same flexural strength but with different reinforcement arrangements are considered and modelling of cracks of RC beams has been done at different degrees of corrosion in the case of delamination using boundary conditions of Three Point Bending Test. Finite Element Analysis (FEA) has been done at different degree of corrosion to observe the variation of different parameters like modal frequency, Elasticity and Flexural strength in case of delamination. Also, the comparison between two different RC arrangements is made to conclude which one of them is more suitable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=delamination" title="delamination">delamination</a>, <a href="https://publications.waset.org/abstracts/search?q=elasticity" title=" elasticity"> elasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=FEA" title=" FEA"> FEA</a>, <a href="https://publications.waset.org/abstracts/search?q=flexural%20strength" title=" flexural strength"> flexural strength</a>, <a href="https://publications.waset.org/abstracts/search?q=modal%20frequency" title=" modal frequency"> modal frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=RC%20beam" title=" RC beam"> RC beam</a> </p> <a href="https://publications.waset.org/abstracts/57700/structural-properties-of-rc-beam-with-progression-of-corrosion-induced-delamination-cracking" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57700.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">426</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> A Parametric Study on Effects of Internal Factors on Carbonation of Reinforced Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kunal%20Tongaria">Kunal Tongaria</a>, <a href="https://publications.waset.org/abstracts/search?q=Abhishek%20Mangal"> Abhishek Mangal</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Mandal"> S.

Therefore, in spite of numerous literature and database, the useful generalization is not an easy task. These interdependent parameters can be grouped under the category of internal and external factors. This paper focuses on the internal parameters which govern and increase the probability of the ingress of deleterious substances into concrete. The mechanism of effects of internal parameters such as microstructure for with and without supplementary cementing materials (SCM), water/binder ratio, the age of concrete etc. has been discussed. This is followed by the comparison of various proposed mathematical models for the deterioration of concrete. Based on existing laboratory experiments as well as field results, this paper concludes the present understanding of mechanism, modeling and future research needs in this field. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbonation" title="carbonation">carbonation</a>, <a href="https://publications.waset.org/abstracts/search?q=diffusion%20coefficient" title=" diffusion coefficient"> diffusion coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure%20of%20concrete" title=" microstructure of concrete"> microstructure of concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete" title=" reinforced concrete"> reinforced concrete</a> </p> <a href="https://publications.waset.org/abstracts/57694/a-parametric-study-on-effects-of-internal-factors-on-carbonation-of-reinforced-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57694.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">408</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> Analysis of Cracked Beams with Spalling Having Different Arrangements of the Reinforcement Bars Using Finite Element Analysis (FEA)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rishabh%20Shukla">Rishabh Shukla</a>, <a href="https://publications.waset.org/abstracts/search?q=Achin%20Agrawal"> Achin Agrawal</a>, <a href="https://publications.waset.org/abstracts/search?q=Anupam%20Saxena"> Anupam Saxena</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Mandal"> S.

This paper focuses on recognizing the parameters that gets changed due to the formation of cracks and have a great impact on the performance of the structure. Spalling is a major concern as it leaves the reinforcement bars more susceptible to environmental attacks. Beams of cross section 300 mm × 500 mm are designed and for a calculated area of steel, two different arrangements of reinforced bars are analysed. Results are prepared for different stages of cracking for each arrangement of rebars. The parameters for both arrangements are then compared. The Finite Element Analysis (FEA) is carried out and changes in the properties like flexural strength, Elasticity and modal frequency are reported. The conclusions have been drawn by comparing the results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cracks" title="cracks">cracks</a>, <a href="https://publications.waset.org/abstracts/search?q=elasticity" title=" elasticity"> elasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=spalling" title=" spalling"> spalling</a>, <a href="https://publications.waset.org/abstracts/search?q=FEA" title=" FEA"> FEA</a> </p> <a href="https://publications.waset.org/abstracts/57697/analysis-of-cracked-beams-with-spalling-having-different-arrangements-of-the-reinforcement-bars-using-finite-element-analysis-fea" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57697.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">279</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> An Unusual Fracture Pattern: Fracture of the Distal Radius (Colles') along with Fracture of the Ipsilateral Scaphoid & Capitate Bones</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Srikanta%20Tagore%20Sarkar">Srikanta Tagore Sarkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Prasanta%20Kumar%20Mandal"> Prasanta Kumar Mandal</a>, <a href="https://publications.waset.org/abstracts/search?q=Dibakar%20Roy"> Dibakar Roy </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The association of a capitate fracture with a scaphoid fracture has been termed as the naviculocapitate syndrome. The existence of some nondisplaced fractures of scaphoid and capitate with or without the fracture of lunate or radius suggests that there is a spectrum of these injuries, and this confuses the terminology. With our case; we report an unusual variety of this naviculocapitate syndrome with distal radial Colles fracture in addition to the nondisplaced fractures of the scaphoid, capitate and the dorsal lip of radial fracture. When we looked at the literature there is no another Colles fracture reported together with undisplaced scapho-capitate syndrome.

The Particle Swarm Optimization (PSO) method, which represents a new approach for optimization problems in electromagnetic, is used in the optimization process. The PSO is used to determine the optimal set of ‘ON-OFF’ elements that provides a radiation pattern with maximum SLL reduction. Optimization is done without prefixing the value of First Null Beam Width (FNBW). The variation of SLL with element spacing of thinned array is also reported. Simulation results show that the number of array elements can be reduced by more than 50% of the total number of elements in the array with a simultaneous reduction in SLL to less than -27dB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thinned%20array" title="thinned array">thinned array</a>, <a href="https://publications.waset.org/abstracts/search?q=Particle%20Swarm%20Optimization" title=" Particle Swarm Optimization"> Particle Swarm Optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=Elliptical%20Cylindrical%20Array" title=" Elliptical Cylindrical Array"> Elliptical Cylindrical Array</a>, <a href="https://publications.waset.org/abstracts/search?q=Side%20Lobe%20Label." title=" Side Lobe Label."> Side Lobe Label.</a> </p> <a href="https://publications.waset.org/abstracts/4068/thinned-elliptical-cylindrical-antenna-array-synthesis-using-particle-swarm-optimization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4068.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">443</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> Modelling the Effects of External Factors Affecting Concrete Carbonation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abhishek%20Mangal">Abhishek Mangal</a>, <a href="https://publications.waset.org/abstracts/search?q=Kunal%20Tongaria"> Kunal Tongaria</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Mandal"> S.

With increasing emissions from various activities, carbon dioxide concentration in the atmosphere has been eve rising, enhancing its penetration in porous concrete, reaching steel bars and ultimately leading to premature failure. Several literatures have been published dealing with the various interdependent variables related to carbonation. However, with innumerable variability a generalization of these data proves to be a troublesome task. This paper looks into this carbonation anomaly in concrete structures caused by various external variables such as relative humidity, concentration of CO2, curing period and ambient temperature. Significant discussions and comparisons have been presented on the basis of various studies conducted with an aim to predict the depth of carbonation as a function of these multidimensional parameters using various numerical and statistical modelling techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbonation" title="carbonation">carbonation</a>, <a href="https://publications.waset.org/abstracts/search?q=curing" title=" curing"> curing</a>, <a href="https://publications.waset.org/abstracts/search?q=exposure%20conditions" title=" exposure conditions"> exposure conditions</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20humidity" title=" relative humidity"> relative humidity</a> </p> <a href="https://publications.waset.org/abstracts/57691/modelling-the-effects-of-external-factors-affecting-concrete-carbonation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57691.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">253</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">42</span> Bending Behaviour of Fiber Reinforced Polymer Composite Stiffened Panel Subjected to Transverse Loading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Kumar">S.

Circular array antenna laid on x-y plane is assumed. FFA is applied on circular arrays of 8-, 10-, and 12- elements.

Such limitation can be overcome by a modification in the process at the time of mixing of ingredients (fly and activator fluid) for geopolymer concrete so that curing can be made at ambient temperature. This process modified geopolymer concrete shows an appreciable improvement in structural performance compared to conventional heat cured geopolymer concrete and control cement concrete. The improved durability performance based on water absorption, sulphate test, and RCPT is also noted. The microstructural properties analyzed through Field Emission Scanning Electron Microscope (FESEM) with Energy Dispersive X-ray Spectroscopy (EDS) and X-ray Diffraction (XRD) techniques show the better interaction of fly ash and activator solution at early ages for the process modified geopolymer concrete.

The micro structure of the sample was observed by SEM, which displays grains of different shapes having diameter in range of 2 µm–4 µm. We have studied the frequency and temperature dependence of permittivity and impedance of the compound with LCR Meter in the range of 100 Hz–1 MHz and 300–500 K. The material shows its highest dielectric constant (428000) at 100 Hz and 368 K. The material shows Debye–like relaxation and their dielectric constant are independent of frequency and temperature over a wide range. The sample shows two electrical responses in impedance formalism, indicating that there are two distinct contributions.

On the other hand, Ethylenediaminetetraacetic acid is a widely used metal chelating agent that, due to its poor biodegradability, is an incessant pollutant to the environment. For the first time, a green, simple, and cost-effective approach is used to hydrothermally synthesise photoluminescent carbon dots using Moringa Oleifera Gum in a single step. Then, using Moringa Oleifera Gum-derived carbon dots, a photoluminescent "ON-OFF-ON" mechanism for dual mode detection of trace Pb2+ and EDTA was proposed. MOG-CDs detect Pb2+ selectively and sensitively using a photoluminescence quenching mechanism, with a detection limit (LOD) of 0.000472 ppm. (1.24 nM). The quenched photoluminescence can be restored by adding EDTA to the MOG-CD+Pb2+ system; this strategy is used to quantify EDTA at a level of detection of 0.0026 ppm. (8.9 nM). The quantification of Pb2+ and EDTA in actual samples encapsulated the applicability and dependability of the proposed photoluminescent probe. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20dots" title="carbon dots">carbon dots</a>, <a href="https://publications.waset.org/abstracts/search?q=photoluminescence" title=" photoluminescence"> photoluminescence</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor" title=" sensor"> sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=moringa%20oleifera%20gum" title=" moringa oleifera gum"> moringa oleifera gum</a> </p> <a href="https://publications.waset.org/abstracts/165332/dual-mode-turn-on-off-on-photoluminescence-detection-of-edta-and-lead-using-moringa-oleifera-gum-derived-carbon-dots" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165332.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">114</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">36</span> Temperature-Dependent Structural Characterization of Type-II Dirac Semi-Metal nite₂ From Bulk to Exfoliated Thin Flakes Using Raman Spectroscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Minna%20Theres%20James">Minna Theres James</a>, <a href="https://publications.waset.org/abstracts/search?q=Nirmal%20K%20Sebastian"> Nirmal K Sebastian</a>, <a href="https://publications.waset.org/abstracts/search?q=Shoubhik%20Mandal"> Shoubhik Mandal</a>, <a href="https://publications.waset.org/abstracts/search?q=Pramita%20Mishra"> Pramita Mishra</a>, <a href="https://publications.waset.org/abstracts/search?q=R%20Ganesan"> R Ganesan</a>, <a href="https://publications.waset.org/abstracts/search?q=P%20S%20Anil%20Kumar"> P S Anil Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We report the temperature-dependent evolution of Raman spectra of type-II Dirac semimetal (DSM) NiTe2 (001) in the form of bulk single crystal and a nanoflake (200 nm thick) for the first time. A physical model that can quantitatively explain the evolution of out of plane A1g and in-plane E1g Raman modes is used. The non-linear variation of peak positions of the Raman modes with temperature is explained by anharmonic three-phonon and four-phonon processes along with thermal expansion of the lattice. We also observe prominent effect of electron-phonon coupling from the variation of FWHM of the peaks with temperature, indicating the metallicity of the samples.

In Nepal it is reported that more than 4.3% of Nepalese population at any time in their life has been infected with Hepatitis-B virus (HBV). The objective of this study was to evaluate the effectiveness of planned educational programme regarding knowledge and practice of hepatitis-B among the nurses working at medical units of BPKIHS. Pre-experimental research design was used to conduct the study among the nurses working in medical units of BPKIHS. Total 40 nurses were included in the pre-test and 34 in the post-test. The education intervention was arranged on 24th May 2012 from 2:15 pm to 4:45 pm i.e. two and half hours. After two weeks of education intervention post-test was conducted. Most of the participants (60%) were of the age group of 18-22 years, Hindu (82.5%), and unmarried (65%). After education intervention there is significant differences in knowledge on the components of Hepatitis-B at 0.05 level of significance. There is no difference in the attitude components after post-test except the component patient contaminated with Hepatitis-B must be called as the last patient (p=0.035). It can conclude that hepatitis-B educational program improved knowledge and practice among the nurses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=educational%20program" title="educational program">educational program</a>, <a href="https://publications.waset.org/abstracts/search?q=Hepatitis-B" title=" Hepatitis-B"> Hepatitis-B</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-experimental%20design" title=" pre-experimental design"> pre-experimental design</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20units" title=" medical units "> medical units </a> </p> <a href="https://publications.waset.org/abstracts/16607/effects-of-an-educational-program-on-nurses-knowledge-and-practice-related-to-hepatitis-b-pre-experimental-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16607.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">34</span> Dispersion-Less All Reflective Split and Delay Unit for Ultrafast Metrology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akansha%20Tyagi">Akansha Tyagi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehar%20S.%20Sidhu"> Mehar S.

We have validated our delay line with NIR –femtosecond pulse measurement centered at 800 nm using second harmonic-Interferometric frequency resolved optical gating (SH-IFROG). The delay line is compact, easy to align and provides attosecond stability and precision and thus make it more versatile for wide range of applications in ultrafast measurements.

Material and Methods: Dried, powdered bark of F. religiosa was extracted successively using petroleum ether and 70% ethanol in soxhlet extractor. The extracts obtained were screened for immunomodulatory activity by delayed type hypersensitivity (DTH), neutrophil adhesion test and cyclophosphamide-induced neutropenia in Swiss albino mice at the dose of 50 and 100 mg/kg, i.p. 70% ethanol extract showed significant immunostimulant activity hence subjected to column chromatography to produce tyrosine rich fraction (TRF). TRF obtained was screened for immunomodulatory activity by above methods at the dose of 10 mg/kg, i.p. Results: TRF showed potentiation of DTH response in terms of significant increase in the mean difference in foot-pad thickness and it significantly increased neutrophil adhesion to nylon fibers by 48.20%. Percentage reduction in total leukocyte count and neutrophil by TRF was found to be 43.85% and 18.72%, respectively. Conclusion: Immunostimulant activity of TRF was more pronounced and thus it has great potential as a source for natural health products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ficus%20religiosa" title="Ficus religiosa">Ficus religiosa</a>, <a href="https://publications.waset.org/abstracts/search?q=immunomodulatory" title=" immunomodulatory"> immunomodulatory</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclophosphamide" title=" cyclophosphamide"> cyclophosphamide</a>, <a href="https://publications.waset.org/abstracts/search?q=neutropenia" title=" neutropenia"> neutropenia</a> </p> <a href="https://publications.waset.org/abstracts/26530/tyrosine-rich-fraction-as-an-immunomodulatory-agent-from-ficus-religiosa-bark" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26530.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">446</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">32</span> Stabilization of Fly Ash Slope Using Plastic Recycled Polymer and Finite Element Analysis Using Plaxis 3D</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tushar%20Vasant%20Salunkhe">Tushar Vasant Salunkhe</a>, <a href="https://publications.waset.org/abstracts/search?q=Sariput%20M.%20Nawghare"> Sariput M.

In this experiment, fly ash is used as a filling material, and Plastic Recycled Polymers of diameter = 3mm and length = 4mm were made from the waste plastic product (lower grade plastic product). The properties of fly ash and plastic recycled polymers are determined. From the experiments, load and settlement have measured. From these data, load–settlement curves have been reported. It has been observed from test results that the load carrying capacity of mixture fly ash with Plastic Recycled Polymers slope is more than that of fly ash slope. The deformation of Plastic Recycled Polymers slope is slightly more than that of fly ash slope. A Finite Element Method (F.E.M.) was also evaluated using PLAXIS 3D version. The failure pattern, deformations and factor of safety are reported based on analytical programme. The results from experimental data and analytical programme are compared and reported. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=factor%20of%20safety" title="factor of safety">factor of safety</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method%20%28FEM%29" title=" finite element method (FEM)"> finite element method (FEM)</a>, <a href="https://publications.waset.org/abstracts/search?q=fly%20ash" title=" fly ash"> fly ash</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20recycled%20polymer" title=" plastic recycled polymer"> plastic recycled polymer</a> </p> <a href="https://publications.waset.org/abstracts/23379/stabilization-of-fly-ash-slope-using-plastic-recycled-polymer-and-finite-element-analysis-using-plaxis-3d" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23379.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">428</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">31</span> Effects of Rice Plant Extracts and Phenolic Allelochemicals on Seedling Growth of Radish</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Shamim%20Hasan%20Mandal">Mohammad Shamim Hasan Mandal</a>, <a href="https://publications.waset.org/abstracts/search?q=Phu%20Minh"> Phu Minh</a>, <a href="https://publications.waset.org/abstracts/search?q=Do%20Tan%20%20Khang"> Do Tan Khang</a>, <a href="https://publications.waset.org/abstracts/search?q=Phung%20Thi%20Tuyen"> Phung Thi Tuyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Tran%20Dang%20Xuan"> Tran Dang Xuan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rice (Oryza sativa L.) is one of the major crops of Vietnam which has more than thousands of varieties.

Seven rice varieties were cultivated in the field condition at Hiroshima University, Japan; stems and leaves from each variety were collected later, they were extracted with methanol, hexane, ethyl acetate, butanol, and water. Total phenolic content and total flavonoid contents were high in ethyl acetate extracts. DPPH antioxidant assay results showed that the ethyl acetate extracts had the higher IC50 value. Therefore, the ethyl acetate extracts were selected for laboratory experimentation through petri dish assay.

Usually has been noticed that criticality of surface temperature increases from the periphery to the urban centre. As the centre experiences maximum severity of heat throughout the year, it also represents most critical zone in terms of thermal condition. In this present study, an attempt has been taken to propose a quantitative approach of thermal critical zonation (TCZ) on the basis of seasonal temperature variation. Here the zonation is done by calculating thermal critical value (TCV). From the Landsat 8 thermal digital data of summer and winter seasons for the year 2014, the land surface temperature maps and thermally critical zonation has been prepared, and corresponding dataset has been computed to conduct the overall study of that particular study area. It is shown that TCZ can be clearly identified and analyzed by the help of inter-seasonal temperature range. The results of this study can be utilized effectively in future urban development and planning projects as well as a framework for implementing rules and regulations by the authorities for a sustainable urban development through an environmentally affable approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermal%20critical%20values%20%28TCV%29" title="thermal critical values (TCV)">thermal critical values (TCV)</a>, <a href="https://publications.waset.org/abstracts/search?q=thermally%20critical%20zonation%20%28TCZ%29" title=" thermally critical zonation (TCZ)"> thermally critical zonation (TCZ)</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20surface%20temperature%20%28LST%29" title=" land surface temperature (LST)"> land surface temperature (LST)</a>, <a href="https://publications.waset.org/abstracts/search?q=Landsat%208" title=" Landsat 8"> Landsat 8</a>, <a href="https://publications.waset.org/abstracts/search?q=Kolkata%20Municipal%20Corporation%20%28KMC%29" title=" Kolkata Municipal Corporation (KMC)"> Kolkata Municipal Corporation (KMC)</a> </p> <a href="https://publications.waset.org/abstracts/85395/identification-of-thermally-critical-zones-based-on-inter-seasonal-variation-in-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85395.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">197</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">29</span> Aerodynamic Study of Formula 1 Car in Upsight Down Configuration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hrishit%20Mitra">Hrishit Mitra</a>, <a href="https://publications.waset.org/abstracts/search?q=Saptarshi%20Mandal"> Saptarshi Mandal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study of aerodynamics for Formula 1 cars is very crucial in determining their performance. In the current F1 industry, when each engine manufacturer exhibits a torque and peak speed that differ by less than 5%, the emphasis on maximizing performance is dependent heavily on the utilization of aerodynamics. This work examines the aerodynamic characteristics of an F1 car by utilizing computational fluid dynamics in order to substantiate the hypothesis that an F1 car can go upside down in a tunnel without any external assistance, only due to the downforce it produces. In addition to this, this study also suggests the implementation of a 'flexi-wing' front in F1 cars to optimize downforce and reduce drag. Furthermore, this paper provides a concise overview of the historical development of aerodynamics in F1, with a specific emphasis on the progression of aerodynamics and the impact of downforce on the dynamics of vehicles. Next, an examination of wings has been provided, comparing the performance of the suggested wing at high speeds and low speeds. Three simulations have been conducted: one to test the complete aerodynamics and validate the hypothesis discussed above, and two specifically focused on the flexi wing, one at high speed and one at low speed. The collected results have been examined to analyze the performance of the front flexi wing. Performance analysis was conducted from the measurement of downforce and drag coefficient, as well as the pressure and velocity distributions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high%20speed%20flexi%20wing" title="high speed flexi wing">high speed flexi wing</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20speed%20flexi%20wing" title=" low speed flexi wing"> low speed flexi wing</a>, <a href="https://publications.waset.org/abstracts/search?q=F1%20car%20aerodynamics" title=" F1 car aerodynamics"> F1 car aerodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=F1%20car%20drag%20reduction" title=" F1 car drag reduction"> F1 car drag reduction</a> </p> <a href="https://publications.waset.org/abstracts/193464/aerodynamic-study-of-formula-1-car-in-upsight-down-configuration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193464.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">12</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> Electrical Transport in Bi₁Sb₁Te₁.₅Se₁.₅ /α-RuCl₃ Heterostructure Nanodevices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shoubhik%20Mandal">Shoubhik Mandal</a>, <a href="https://publications.waset.org/abstracts/search?q=Debarghya%20Mallick"> Debarghya Mallick</a>, <a href="https://publications.waset.org/abstracts/search?q=Abhishek%20Banerjee"> Abhishek Banerjee</a>, <a href="https://publications.waset.org/abstracts/search?q=R.%20Ganesan"> R.

Bi₁Sb₁Te₁.₅Se₁.₅ (BSTS) is a strong three-dimensional topological insulator (3D-TI) that hosts conducting topological surface states (TSS) enclosing an insulating bulk. α-RuCl₃ (namely, RuCl₃) is an anti-ferromagnet that is predicted to behave as a Kitaev-like quantum spin liquid carrying Majorana excitations. Temperature (T)-dependent resistivity measurements show the interplay between parallel bulk and surface transport channels. At T < 150 K, surface state transport dominates over bulk transport. Multi-channel weak anti-localization (WAL) is observed, as a sharp cusp in the magnetoconductivity, indicating strong spin-orbit coupling. The presence of top and bottom topological surface states (TSS), including a pair of electrically coupled Rashba surface states (RSS), are indicated. Non-linear Hall effect, explained by a two-band model, further supports this interpretation. Finally, a low-T logarithmic resistance upturn is analyzed using the Lu-Shen model, supporting the presence of gapless surface states with a π Berry phase. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=topological%20materials" title="topological materials">topological materials</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20transport" title=" electrical transport"> electrical transport</a>, <a href="https://publications.waset.org/abstracts/search?q=Lu-Shen%20model" title=" Lu-Shen model"> Lu-Shen model</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20spin%20liquid" title=" quantum spin liquid"> quantum spin liquid</a> </p> <a href="https://publications.waset.org/abstracts/149012/electrical-transport-in-bi1sb1te15se15-a-rucl3-heterostructure-nanodevices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149012.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">121</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> A Theoretical Modelling and Simulation of a Surface Plasmon Resonance Biosensor for the Detection of Glucose Concentration in Blood and Urine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Natasha%20Mandal">Natasha Mandal</a>, <a href="https://publications.waset.org/abstracts/search?q=Rakesh%20Singh%20Moirangthem"> Rakesh Singh Moirangthem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present work reports a theoretical model to develop a plasmonic biosensor for the detection of glucose concentrations in human blood and urine as the abnormality of glucose label is the major cause of diabetes which becomes a life-threatening disease worldwide. This study is based on the surface plasmon resonance (SPR) sensor applications which is a well-established, highly sensitive, label-free, rapid optical sensing tool. Here we have introduced a sandwich assay of two dielectric spacer layers of MgF2 and BaTiO3which gives better performance compared to commonly used SiO2 and TiO2 dielectric spacers due to their low dielectric loss and higher refractive index. The sensitivity of our proposed sensor was found as 3242 nm/RIU approximately, with an excellent linear response of 0.958, which is higher than the conventional single-layer Au SPR sensor. Further, the sensitivity enhancement is also optimized by coating a few layers of two-dimensional (2D) nanomaterials (e.g., Graphene, h-BN, MXene, MoS2, WS2, etc.) on the sensor chip. Hence, our proposed SPR sensor has the potential for the detection of glucose concentration in blood and urine with enhanced sensitivity and high affinity and could be utilized as a reliable platform for the optical biosensing application in the field of medical diagnosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biosensor" title="biosensor">biosensor</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20plasmon%20resonance" title=" surface plasmon resonance"> surface plasmon resonance</a>, <a href="https://publications.waset.org/abstracts/search?q=dielectric%20spacer" title=" dielectric spacer"> dielectric spacer</a>, <a href="https://publications.waset.org/abstracts/search?q=2D%20nanomaterials" title=" 2D nanomaterials"> 2D nanomaterials</a> </p> <a href="https://publications.waset.org/abstracts/152759/a-theoretical-modelling-and-simulation-of-a-surface-plasmon-resonance-biosensor-for-the-detection-of-glucose-concentration-in-blood-and-urine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152759.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">106</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> Procedural Protocol for Dual Energy Computed Tomography (DECT) Inversion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rezvan%20Ravanfar%20Haghighi">Rezvan Ravanfar Haghighi</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Chatterjee"> S.

In the present paper, we aim to obtain a numerical algorithm by which (ρe, Zeff) can be obtained from the HU(100) and HU(140) data, where V=100, 140 kVp. The idea is to use this inversion method to characterize and distinguish between the lipid and fibrous coronary artery plaques.With the idea to develop the inversion algorithm for low Zeff materials, as is the case with non calcified coronary artery plaque, we prepare aqueous samples whose calculated values of (ρe, Zeff) lie in the range (2.65×1023≤ ρe≤ 3.64×1023 per cc ) and (6.80≤ Zeff ≤ 8.90). We fill the phantom with these known samples and experimentally determine HU(100) and HU(140) for the same pixels. Knowing that the HU(V) values are related to the attenuation coefficient of the system, we present an algorithm by which the (ρe, Zeff) is calibrated with respect to (HU(100), HU(140)). The calibration is done with a known set of 20 samples; its accuracy is checked with a different set of 23 known samples. We find that the calibration gives the ρe with an accuracy of ± 4% while Zeff is found within ±1% of the actual value, the confidence being 95%.In this inversion method (ρe, Zeff) of the scanned sample can be found by eliminating the effects of the CT machine and also by ensuring that the determination of the two unknowns (ρe, Zeff) does not interfere with each other. It is found that this algorithm can be used for prediction of chemical characteristic (ρe, Zeff) of unknown scanned materials with 95% confidence level, by inversion of the DECT data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20composition" title="chemical composition">chemical composition</a>, <a href="https://publications.waset.org/abstracts/search?q=dual-energy%20computed%20tomography" title=" dual-energy computed tomography"> dual-energy computed tomography</a>, <a href="https://publications.waset.org/abstracts/search?q=inversion%20algorithm" title=" inversion algorithm"> inversion algorithm</a> </p> <a href="https://publications.waset.org/abstracts/38567/procedural-protocol-for-dual-energy-computed-tomography-dect-inversion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38567.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">438</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> Use of Amaranthus Roxburghianus Root Extract in the Treatment of Ulcerative Colitis in Mice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20A.%20Nirmal">S.

(Amaranthaceae) root alone and in combination with piperine in treating ulcerative colitis (UC) in mice. Swiss albino mice were divided into seven groups (n = 6). Standard group received prednisolone (5 mg/kg, i.p.). Treatment groups received hydroalcoholic extract of roots of A. roxburghianus (50 and 100 mg/kg, p.o.) and a combination of hydroalcoholic extract of roots of A. roxburghianus (50 and 100 mg/kg, p.o.) and piperine (5 mg/kg, p.o.). Ulcer index, colitis severity, myeloperoxidase (MPO), malondialdehyde and glutathione were estimated from blood and tissue. Column chromatography of the extract was done and purified fractions were analyzed by gas chromatography-mass spectroscopy (GC-MS). Treatment with the combination of hydroalcoholic extract of A. roxburghianus and piperine showed minimal ulceration, hemorrhage, necrosis and leucocyte infiltration by histopathological observation. Acetic acid increased MPO levels in blood and colon tissue to 355 U/mL and 385 U/mg, respectively. The combination of hydroalcoholic extract (100 mg/kg) and piperine (5 mg/kg) significantly decreased MPO in blood and tissue to 182 U/mL and 193 U/mg, respectively. Similarly, this combination significantly reduced MPO and increased glutathione levels in blood and tissue. Various phytoconstituents were detected by GC-MS. The combination of hydroalcoholic extract and piperine is effective in the treatment of UC and the effects are comparable with the standard drug prednisolone. 4H-pyran-4-one, 2,3-dihydro-3,5-dihydroxy-6-methyl, eugenol and benzene, and 1-(1,5-dimethyl-4-hexenyl)-4-methyl are reported having analgesic, anti-inflammatory, and antioxidant properties; they may play a role in the biological activity of A. roxburghianus root. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amaranthus%20roxburghianus" title="Amaranthus roxburghianus">Amaranthus roxburghianus</a>, <a href="https://publications.waset.org/abstracts/search?q=ulcerative%20colitis" title=" ulcerative colitis"> ulcerative colitis</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-inflammatory" title=" anti-inflammatory"> anti-inflammatory</a>, <a href="https://publications.waset.org/abstracts/search?q=ulcerative%20colitis" title=" ulcerative colitis"> ulcerative colitis</a> </p> <a href="https://publications.waset.org/abstracts/18289/use-of-amaranthus-roxburghianus-root-extract-in-the-treatment-of-ulcerative-colitis-in-mice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18289.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">528</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> Comparative Performance Study of Steel Plate Shear Wall with Reinforced Concrete Shear Wall</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amit%20S.%20Chauhan">Amit S.

They are incorporated in buildings to resist lateral forces and support the gravity loads. The steel plate shear walls (SPSWs) are used as lateral load resisting systems for buildings and acts as an alternative to reinforced concrete shear walls (RCSWs). This paper compares the behavior of SPSW with the RCSW incorporated in a building frame having G+6 storey, located in Zone III, using the technique of Equivalent Static Method (ESM) as per Indian Standard Criteria For Earthquake Resistant Design of Structures IS 1893:2002. This paper intends to evaluate several parameters such as lateral displacement at tip, inter-storey drift, weight of steel and volume of concrete with the alteration of the shear wall with respect to different types viz., SPSW and RCSW. The strip model employed in this study is a widely accepted analytical tool for SPSW analysis. SPSW can be modelled as truss members by using a series of diagonal tension strips positioned at 45-degree angles. In this paper, by replacing the SPSWs with the tension strips, the G+6 building has been analyzed using STAAD.Pro V8i. Based on the present study, it can be concluded that structure with SPSWs is much better then structure with RCSWs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=equivalent%20static%20method" title="equivalent static method">equivalent static method</a>, <a href="https://publications.waset.org/abstracts/search?q=inter-storey%20drift" title=" inter-storey drift"> inter-storey drift</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20displacement" title=" lateral displacement"> lateral displacement</a>, <a href="https://publications.waset.org/abstracts/search?q=Steel%20plate%20shear%20wall" title=" Steel plate shear wall"> Steel plate shear wall</a>, <a href="https://publications.waset.org/abstracts/search?q=strip%20model" title=" strip model"> strip model</a> </p> <a href="https://publications.waset.org/abstracts/57698/comparative-performance-study-of-steel-plate-shear-wall-with-reinforced-concrete-shear-wall" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57698.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">246</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> Analytic Hierarchy Process and Multi-Criteria Decision-Making Approach for Selecting the Most Effective Soil Erosion Zone in Gomati River Basin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Chakraborty">Rajesh Chakraborty</a>, <a href="https://publications.waset.org/abstracts/search?q=Dibyendu%20Das"> Dibyendu Das</a>, <a href="https://publications.waset.org/abstracts/search?q=Rabindra%20Nath%20Barman"> Rabindra Nath Barman</a>, <a href="https://publications.waset.org/abstracts/search?q=Uttam%20Kumar%20Mandal"> Uttam Kumar Mandal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present study, the objective is to find out the most effective zone causing soil erosion in the Gumati river basin located in the state of Tripura, a north eastern state of India using analytical hierarchy process (AHP) and multi-objective optimization on the basis of ratio analysis (MOORA).The watershed is segmented into 20 zones based on Area. The watershed is considered by pointing the maximum elevation from sea lever from Google earth. The soil erosion is determined using the universal soil loss equation. The different independent variables of soil loss equation bear different weightage for different soil zones. And therefore, to find the weightage factor for all the variables of soil loss equation like rainfall runoff erosivity index, soil erodibility factor etc, analytical hierarchy process (AHP) is used. And thereafter, multi-objective optimization on the basis of ratio analysis (MOORA) approach is used to select the most effective zone causing soil erosion. The MCDM technique concludes that the maximum soil erosion is occurring in the zone 14. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soil%20erosion" title="soil erosion">soil erosion</a>, <a href="https://publications.waset.org/abstracts/search?q=analytic%20hierarchy%20process%20%28AHP%29" title=" analytic hierarchy process (AHP)"> analytic hierarchy process (AHP)</a>, <a href="https://publications.waset.org/abstracts/search?q=multi%20criteria%20decision%20making%20%28MCDM%29" title=" multi criteria decision making (MCDM)"> multi criteria decision making (MCDM)</a>, <a href="https://publications.waset.org/abstracts/search?q=universal%20soil%20loss%20equation%20%28USLE%29" title=" universal soil loss equation (USLE)"> universal soil loss equation (USLE)</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-objective%20optimization%20on%20the%20basis%20of%20ratio%20analysis%20%28MOORA%29" title=" multi-objective optimization on the basis of ratio analysis (MOORA)"> multi-objective optimization on the basis of ratio analysis (MOORA)</a> </p> <a href="https://publications.waset.org/abstracts/37548/analytic-hierarchy-process-and-multi-criteria-decision-making-approach-for-selecting-the-most-effective-soil-erosion-zone-in-gomati-river-basin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37548.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">538</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> Exploring Paper Mill Sludge and Sugarcane Bagasse as Carrier Matrix in Solid State Fermentation for Carotenoid Pigment Production by Planococcus sp.

These pigments are of immense pharmacological importance as antioxidant, anticancer, eye and liver protective agent, etc. The production of this pigment in a cost effective manner is a challenging task. The present study explored paper mill sludge (PMS), a solid lignocellulosic waste generated in large quantities from pulp and paper mill industry as a substrate for carotenoid pigment production by Planococcus sp. TRC1. PMS was compared in terms of efficacy with sugarcane bagasse, which is a highly explored substrate for valuable product generation via solid state fermentation. The results showed that both the biomasses yielded the highest carotenoid during 48 hours of incubation, 31.6 mg/gm and 42.1 mg/gm for PMS and bagasse respectively. Compositional alterations of both the biomasses showed reduction in lignin, hemicellulose and cellulose content by 41%, 15%, 1% for PMS and 38%, 25% and 6% for sugarcane bagasse after 72 hours of incubation. Structural changes in the biomasses were examined by FT-IR, FESEM, and XRD which further confirmed modification of solid biomasses by bacterial isolate. This study revealed the potential of PMS to act as cheap substrate for carotenoid pigment production by Planococcus sp. TRC1, as it showed a significant production in comparison to sugarcane bagasse which gave only 1.3 fold higher production than PMS. Delignification of PMS by TRC1 during pigment production is another important finding for the reuse of this waste from the paper industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carotenoid" title="carotenoid">carotenoid</a>, <a href="https://publications.waset.org/abstracts/search?q=lignocellulosic" title=" lignocellulosic"> lignocellulosic</a>, <a href="https://publications.waset.org/abstracts/search?q=paper%20mill%20sludge" title=" paper mill sludge"> paper mill sludge</a>, <a href="https://publications.waset.org/abstracts/search?q=Planococcus%20sp.%20TRC1" title=" Planococcus sp.

Since large blood vessels and peripheral blood vessels are of same mesodermal origin, therefore, involvement of the latter in regulation of cardiorespiratory system is expected. Role of perivascular nerves in mediating cardiorespiratory alterations produced after intra-arterial injection of a nociceptive agent (bradykinin) was examined in urethane anesthetized male rats. Respiratory frequency, blood pressure, and heart rate were recorded for 30 min after the retrograde injection of bradykinin/saline in the femoral artery. In addition, paw edema was determined and water content was expressed as percentage of wet weight. Injection of bradykinin produced immediate tachypnoeic, hypotensive and bradycardiac responses of shorter latency (5-8 s) favoring the neural mechanisms involved in it. Injection of equi-volume of saline did not produce any responses and served as time matched control. Paw edema was observed in the ipsilateral hind limb. Pretreatment with diclofenac sodium significantly attenuated the bradykinin-induced responses and also blocked the paw edema. Ipsilateral femoral and sciatic nerve sectioning attenuated bradykinin-induced responses significantly indicating the origin of responses from the local vascular bed. Administration of bradykinin in the segment of an artery produced reflex cardiorespiratory changes by stimulating the perivascular nociceptors involving prostaglandins. This is a novel study exhibiting the role of peripheral blood vessels in regulation of cardiorespiratory system. <p class="card-text"><strong>Keywords:</strong> <a
