In today's world, a huge amount of data is available on the web in text format. This has also resulted in the generation of big data in structured and unstructured formats. In general, the data is in the textual form, which is highly unstructured. To get insights and actionable content from this data, we need to incorporate the concepts of text mining and natural language processing. In our study, we mainly focus on Interesting data through which interesting facts are generated for the knowledge base. The approach is to derive the analytics from the text via the application of natural language processing. Using semantic web Resource framework descriptors (RDF), we generate the triple from the given data and derive the interesting patterns. The methodology also illustrates data integration using the RDF for reliable, interesting patterns. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RDF" title="RDF">RDF</a>, <a href="https://publications.waset.org/abstracts/search?q=interestingness" title=" interestingness"> interestingness</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20base" title=" knowledge base"> knowledge base</a>, <a href="https://publications.waset.org/abstracts/search?q=semantic%20data" title=" semantic data"> semantic data</a> </p> <a href="https://publications.waset.org/abstracts/130576/resource-framework-descriptors-for-interestingness-in-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130576.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">162</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">50</span> A Comparative Study of Force Prediction Models during Static Bending Stage for 3-Roller Cone Frustum Bending</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahesh%20Chudasama">Mahesh Chudasama</a>, <a href="https://publications.waset.org/abstracts/search?q=Harit%20Raval"> Harit Raval</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Conical sections and shells of metal plates manufactured by 3-roller conical bending process are widely used in the industries.

It is concluded from the study that for higher bottom roller inclination, the shear stress affects greatly to the static bending force whereas for lower bottom roller inclination it can be neglected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=roller-bending" title="roller-bending">roller-bending</a>, <a href="https://publications.waset.org/abstracts/search?q=static-bending" title=" static-bending"> static-bending</a>, <a href="https://publications.waset.org/abstracts/search?q=stress-conditions" title=" stress-conditions"> stress-conditions</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical-modeling" title=" analytical-modeling"> analytical-modeling</a> </p> <a href="https://publications.waset.org/abstracts/45482/a-comparative-study-of-force-prediction-models-during-static-bending-stage-for-3-roller-cone-frustum-bending" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45482.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">251</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> Uncommon Causes of Acute Abdominal Pain: A Pictorial Essay</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahesh%20Hariharan">Mahesh Hariharan</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajan%20Balasubramaniam"> Rajan Balasubramaniam</a>, <a href="https://publications.waset.org/abstracts/search?q=Sharath%20Kumar%20Shetty"> Sharath Kumar Shetty</a>, <a href="https://publications.waset.org/abstracts/search?q=Shanthala%20Yadavalli"> Shanthala Yadavalli</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Ahetasham"> Mohammed Ahetasham</a>, <a href="https://publications.waset.org/abstracts/search?q=Sravya%20Devarapalli"> Sravya Devarapalli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Acute abdomen is one of the most common clinical conditions requiring a radiological investigation. Ultrasound is the primary modality of choice which can diagnose some of the common causes of acute abdomen. However, sometimes the underlying cause for the pain is far more complicated than expected to mandate a high degree of suspicion to suggest further investigation with contrast-enhanced computed tomography or magnetic resonance imaging. Here, we have compiled a comprehensive series of selected cases to highlight the conditions which can be easily overlooked unless carefully sought for. This also emphasizes the importance of multimodality approach to arrive at the final diagnosis with an increased overall diagnostic accuracy which in turn improves patient management and prognosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acute%20abdomen" title="acute abdomen">acute abdomen</a>, <a href="https://publications.waset.org/abstracts/search?q=contrast-enhanced%20computed%20tomography%20scan" title=" contrast-enhanced computed tomography scan"> contrast-enhanced computed tomography scan</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20resonance%20imaging" title=" magnetic resonance imaging"> magnetic resonance imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=plain%20radiographs" title=" plain radiographs"> plain radiographs</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a> </p> <a href="https://publications.waset.org/abstracts/53361/uncommon-causes-of-acute-abdominal-pain-a-pictorial-essay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53361.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">364</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> Flexural Analysis of Palm Fiber Reinforced Hybrid Polymer Matrix Composite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.Venkatachalam">G.Venkatachalam</a>, <a href="https://publications.waset.org/abstracts/search?q=Gautham%20Shankar"> Gautham Shankar</a>, <a href="https://publications.waset.org/abstracts/search?q=Dasarath%20Raghav"> Dasarath Raghav</a>, <a href="https://publications.waset.org/abstracts/search?q=Krishna%20Kuar"> Krishna Kuar</a>, <a href="https://publications.waset.org/abstracts/search?q=Santhosh%20Kiran"> Santhosh Kiran</a>, <a href="https://publications.waset.org/abstracts/search?q=Bhargav%20Mahesh"> Bhargav Mahesh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Uncertainty in the availability of fossil fuels in the future and global warming increased the need for more environment-friendly materials.

The world is now shifting towards green energy because the utilization of fossil fuels is resulting in global warming. So we need to develop systems that can operate on renewable energy resources and have low heat losses. The combined solar and geothermal multigeneration system can solve this issue. Rather than making rankine cycle purely a solar-driven, heat from solar is used to drive vapour absorption cycle and reheated to generate power using geothermal reservoir. The results are displayed by using Engineering Equation Solver software, where inputs are varied to optimize the energy and exergy efficiencies of the system. The cooling effect is 348.2 KW, while the network output is 23.8 MW and reducing resultant emission of 105553 tons of CO₂ per year.

Therefore a sensitive analytical procedure using UHPLC-ESI-MS/MS was developed and validated for simultaneous quantification of five phenolic compounds in leaf, stem and root extracts of Cassia tora. Rapid chromatographic separation of compounds was achieved on Acquity UHPLC BEH C18 column (50 mm×2.1 mm id, 1.7µm) column in 2.5 min. Quantification was carried out using negative electrospray ionization in multiple-reaction monitoring mode. The method was validated as per ICH guidelines and showed good linearity (r2 ≥ 0.9985) over the concentration range of 0.5-200 ng/mL. The intra- and inter-day precisions and accuracy were within RSDs ≤ 1.93% and ≤ 1.90%, respectively. The developed method was applied to investigate variation of five phenolic compounds in the three geographical collections.

Yet, there still seems to be some existing challenges in terms of validating the performance of PU learning, as the actual truth of unlabeled data points is still unknown in contrast to a binary classification where we know the truth. In this study, we propose a novel PU learning technique based on the Pseudo-F measure, where we address this research gap. In this approach, we train the PU model to discriminate the probability distribution of the positive and unlabeled in the validation and spy data. The predicted probabilities of the PU model have a two-fold validation – (a) the predicted probabilities of reliable positives and predicted positives should be from the same distribution; (b) the predicted probabilities of predicted positives and predicted unlabeled should be from a different distribution. We experimented with this approach on a credit marketing case study in one of the world’s biggest fintech platforms and found evidence for benchmarking performance and backtested using historical data.

These properties represent major advances in the design of organic electronic devices. With the addition of C60 in the conjugated polymer matrix, the primary photo-excitation of the conjugated polymer undergoes an ultrafast electron transfer, and it has been demonstrated that fullerene molecules may serve as efficient electron acceptors in polymeric solar cells. The present paper includes the systematic studies on the effect of electrical, structural and sensor properties of polyaniline (PANI) matrix by the presence of C60. Polyaniline-fullerene (PANI/C60) composite is prepared by the introduction of fullerene during polymerization of aniline with ammonium persulfate and dodechyl benzene sulfonic acid as oxidant and dopant respectively. FTIR spectroscopy indicated the interaction between PANI and C60. X-ray diffraction proved the formation of a PANI/C60 complex. SEM image shows the highly branched chain structure of the PANI in the presence of C60. The conductivity of the PANI/C60 was found to be more than ten orders of magnitude over the pure PANI. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conductivity" title="conductivity">conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=fullerene" title=" fullerene"> fullerene</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposite" title=" nanocomposite"> nanocomposite</a>, <a href="https://publications.waset.org/abstracts/search?q=polyaniline" title=" polyaniline"> polyaniline</a> </p> <a href="https://publications.waset.org/abstracts/57287/electrical-and-structural-properties-of-polyaniline-fullerene-nanocomposite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57287.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">217</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">39</span> Three-Dimensional, Non-Linear Finite Element Analysis of Bullet Penetration through Thin AISI 4340 Steel Target Plate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abhishek%20Soni">Abhishek Soni</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Kumaraswamy"> A.

The effect of large strain, strain-rate and temperature at very high velocity regime was studied from number of simulations of semi-spherical nose shape bullet penetration through single layered circular plate with 2 mm thickness at impact velocities of 500, 1000, and 1500 m/s with the help of Johnson Cook material model. Mie-Gruneisen equation of state is used in conjunction with Johnson Cook material model to determine pressure-volume relationship at various points of interests. Two material models viz. Plastic-Kinematic and Johnson- Cook resulted in different deformation patterns in steel plate. It is observed from the simulation results that the velocity drop and loss of kinetic energy occurred very quickly up to perforation of plate, after that the change in velocity and changes in kinetic energy are negligibly small. The physics behind this kind of behaviour is presented in the paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AISI%204340%20steel" title="AISI 4340 steel">AISI 4340 steel</a>, <a href="https://publications.waset.org/abstracts/search?q=ballistic%20impact%20simulation" title=" ballistic impact simulation"> ballistic impact simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=bullet%20penetration" title=" bullet penetration"> bullet penetration</a>, <a href="https://publications.waset.org/abstracts/search?q=non-linear%20FEM" title=" non-linear FEM"> non-linear FEM</a> </p> <a href="https://publications.waset.org/abstracts/82589/three-dimensional-non-linear-finite-element-analysis-of-bullet-penetration-through-thin-aisi-4340-steel-target-plate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82589.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">208</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">38</span> Numerical Investigation of Static and Dynamic Responses of Fiber Reinforced Sand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandeep%20Kumar">Sandeep Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahesh%20Kumar%20Jat"> Mahesh Kumar Jat</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajib%20Sarkar"> Rajib Sarkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Soil reinforced with randomly distributed fibers is an attractive means to improve the performance of soil in a cost effective manner. Static and dynamic characterization of fiber reinforced soil have become important to evaluate adequate performance for all classes of geotechnical engineering problems. Present study investigates the behaviour of fiber reinforced cohesionless soil through numerical simulation of triaxial specimen. The numerical model has been validated with the existing literature of laboratory triaxial compression testing. A parametric study has been done to find out optimum fiber content for shear resistance. Cyclic triaxial testing has been simulated and the stress-strain response of fiber-reinforced sand has been examined considering different combination of fiber contents. Shear modulus values and damping values of fiber-reinforced sand are evaluated. It has been observed from results that for 1.0 percent fiber content shear modulus increased 2.28 times and damping ratio decreased 4.6 times. The influence of amplitude of cyclic strain, confining pressure and frequency of loading on the dynamic properties of fiber reinforced sand has been investigated and presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damping" title="damping">damping</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber%20reinforced%20soil" title=" fiber reinforced soil"> fiber reinforced soil</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20modelling" title=" numerical modelling"> numerical modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20modulus" title=" shear modulus"> shear modulus</a> </p> <a href="https://publications.waset.org/abstracts/77544/numerical-investigation-of-static-and-dynamic-responses-of-fiber-reinforced-sand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77544.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">278</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">37</span> Glycerol-Free Biodiesel Synthesis from Crude Mahua (Madhuca indica) Oil under Supercritical Methyl Acetate Using CO2 as a Co-Solvent</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antaram%20Sarve">Antaram Sarve</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahesh%20Varma"> Mahesh Varma</a>, <a href="https://publications.waset.org/abstracts/search?q=Shriram%20Sonawane"> Shriram Sonawane</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Conventional route of producing biodiesel with alcohol produces glycerol as side product which leads to oversupply and devaluation in the world market. Supercritical methyl acetate (SCMA) has been proven to convert triglycerides into fatty acid methyl esters (FAMEs) and triacetin, which is a valuable biodiesel additive as side product rather than glycerol. However, due to the low reactivity of supercritical methyl acetate on triglycerides, high reaction conditions are required to obtained maximum yields. The present study describes the renewable approach for the production of biodiesel from low-cost, high acid value mahua oil under supercritical methyl acetate condition using carbon dioxide (CO2) as a co-solvent. CO2 was employed to decrease high reaction conditions required for supercritical methyl acetate transesterification. The inﬂuence of process parameters such as temperature, oil to methyl acetate molar ratio, reaction time, and the CO2 pressure was evaluated. The properties of biodiesel produced were found to be superior compared to conventional biodiesel method. Furthermore, SCMA has a high tolerance towards free fatty acids (FFAs) which is crucial to allow the utilization of inexpensive waste oils as a biodiesel feedstock. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=supercritical%20methyl%20acetate" title="supercritical methyl acetate">supercritical methyl acetate</a>, <a href="https://publications.waset.org/abstracts/search?q=CO2" title=" CO2"> CO2</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiesel" title=" biodiesel"> biodiesel</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20properties" title=" fuel properties"> fuel properties</a> </p> <a href="https://publications.waset.org/abstracts/34550/glycerol-free-biodiesel-synthesis-from-crude-mahua-madhuca-indica-oil-under-supercritical-methyl-acetate-using-co2-as-a-co-solvent" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34550.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">563</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> Sitagliptin-AntiCD4 Mab Conjugated T Cell Targeting Therapy for the Effective Treatment of Type I Diabetes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Mahesh">T.

Samanta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Antibody dug conjugate (ADC’s) concept is a less explored and more trustable for the treatment of Type 1 diabetes (T1D). T1D is thought to arise from selective immunologically mediated destruction of the insulin- producing β-cells in the pancreatic islets of Langerhans with consequent insulin deficiency. It is evident that type 1 diabetes can be conquered, by 1) to stop immune destruction of βcells, 2) to replace or regenerate β-cells, and 3) to preserve β-cell function and mass. Many studies found that the regulatory T cells (Tregs) are crucial for the maintenance of immunological tolerance. Immune tolerance is liable for the activation of the Th1 response. The important role of Th1 response in pathology of T1D entails the depletion of CD4+ T cells, which initiated the use of anti-CD4 monoclonal antibodies (mAbs) against CD4+ T cells to interfere with induction of T1D.Insulin is regulated by Glucagon-Like Peptide-1 hormone (GLP-1) which also stimulates β-cells proliferation as the half-life of GLP-1 harmone is less due to rapid degradation by DPP-IV enzyme an alternative DPP-IV-inhibitors can increase the half-life of GLP-1 through which it conquers the replacement and reserve β-cells mass. Thus in the present study Anti-CD4 mAb was conjugated with Sitagliptin which is a DPP-IV inhibitor Drug loaded in Nanoparticles through Sulfo-MBS cross-linkers. The above study can be an effective approach for treatment to overcome the Passive subcutaneous insulin therapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibody%20drug%20conjugates" title="antibody drug conjugates">antibody drug conjugates</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-CD4%20Mab" title=" anti-CD4 Mab"> anti-CD4 Mab</a>, <a href="https://publications.waset.org/abstracts/search?q=DPP%20IV%20inhibitors" title=" DPP IV inhibitors"> DPP IV inhibitors</a>, <a href="https://publications.waset.org/abstracts/search?q=GLP-1" title=" GLP-1"> GLP-1</a> </p> <a href="https://publications.waset.org/abstracts/21545/sitagliptin-anticd4-mab-conjugated-t-cell-targeting-therapy-for-the-effective-treatment-of-type-i-diabetes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21545.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">390</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Gene Expression Profile Reveals Breast Cancer Proliferation and Metastasis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nandhana%20Vivek">Nandhana Vivek</a>, <a href="https://publications.waset.org/abstracts/search?q=Bhaskar%20Gogoi"> Bhaskar Gogoi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayyavu%20Mahesh"> Ayyavu Mahesh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Breast cancer metastasis plays a key role in cancer progression and fatality. The present study examines the potential causes of metastasis in breast cancer by investigating the novel interactions between genes and their pathways. The gene expression profile of GSE99394, GSE1246464, and GSE103865 was downloaded from the GEO data repository to analyze the differentially expressed genes (DEGs). Protein-protein interactions, target factor interactions, pathways and gene relationships, and functional enrichment networks were investigated. The proliferation pathway was shown to be highly expressed in breast cancer progression and metastasis in all three datasets. Gene Ontology analysis revealed 11 DEGs as gene targets to control breast cancer metastasis: LYN, DLGAP5, CXCR4, CDC6, NANOG, IFI30, TXP2, AGTR1, MKI67, and FTH1. Upon studying the function, genomic and proteomic data, and pathway involvement of the target genes, DLGAP5 proved to be a promising candidate due to it being highly differentially expressed in all datasets. The study takes a unique perspective on the avenues through which DLGAP5 promotes metastasis. The current investigation helps pave the way in understanding the role DLGAP5 plays in metastasis, which leads to an increased incidence of death among breast cancer patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genomics" title="genomics">genomics</a>, <a href="https://publications.waset.org/abstracts/search?q=metastasis" title=" metastasis"> metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=microarray" title=" microarray"> microarray</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer" title=" cancer"> cancer</a> </p> <a href="https://publications.waset.org/abstracts/155120/gene-expression-profile-reveals-breast-cancer-proliferation-and-metastasis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155120.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">97</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> Isolation and Identification of Cytotoxic Compounds from Fruticose Lichen Roccella montagnei, and It’s in Silico Docking Study against CDK-10</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tripti%20Mishra">Tripti Mishra</a>, <a href="https://publications.waset.org/abstracts/search?q=Shipra%20Shukla"> Shipra Shukla</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjeev%20Meena"> Sanjeev Meena</a>, <a href="https://publications.waset.org/abstracts/search?q="></a>, <a href="https://publications.waset.org/abstracts/search?q=Ruchi%20Singh"> Ruchi Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahesh%20Pal"> Mahesh Pal</a>, <a href="https://publications.waset.org/abstracts/search?q=D.%20K.%20Upreti"> D.

As Roccella has been shown to be bioactive, we prepared methanolic extract and assessed its anticancer potential. The methanolic extract showed significant in vitro cytotoxic activity against four human cancer cell lines such as Colon (DLD-1, SW-620), Breast (MCF-7), Head and Neck (FaDu). This prompted us to isolate bioactive compounds through column chromatography. Two compounds Roccellic acid and Everninic acid have been isolated, out of which Everninic acid is reported for the first time. Both the compounds have been tested for in vitro cytotoxic activity in which Roccellic acid showed strong anticancer activity as compared to the Everninic acid. CDK-10 (Cyclin-dependent kinase) contributes to proliferation of cancer cells, and aberrant activity of these kinases has been reported in a wide variety of human cancers. These kinases, therefore, constitute biomarkers of proliferation and attractive pharmacological targets for the development of anticancer therapeutics. Therefore both the isolated compounds were tested for in silico molecular docking study against CDK-10 isomer enzyme to support the cytotoxic activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cytotoxic%20activity" title="cytotoxic activity">cytotoxic activity</a>, <a href="https://publications.waset.org/abstracts/search?q=everninic%20acid" title=" everninic acid"> everninic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=roccellic%20acid" title=" roccellic acid"> roccellic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=R.%20montagnei" title=" R. montagnei"> R. montagnei</a> </p> <a href="https://publications.waset.org/abstracts/56792/isolation-and-identification-of-cytotoxic-compounds-from-fruticose-lichen-roccella-montagnei-and-its-in-silico-docking-study-against-cdk-10" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56792.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">326</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">33</span> In-Silico Evaluation and Antihyperglycemic Potential of Leucas Cephalotes </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anjali%20Verma">Anjali Verma</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahesh%20Pal"> Mahesh Pal</a>, <a href="https://publications.waset.org/abstracts/search?q=Veena%20Pande"> Veena Pande</a>, <a href="https://publications.waset.org/abstracts/search?q=Dalip%20Kumar%20Upreti"> Dalip Kumar Upreti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study is carried out to explore the anti-hyperglycemic activity of Leucas cephalotes plant parts. A fruit, leaves, stems, and roots part of the Leucas cephalotes has been extracted in ethanol and have been evaluated for anti-hyperglycemic activity. The present study indicated that, ethanolic extract of fruit and leaves have shown significant α- amylase inhibitory activity with IC50 value of 92.86 ± 0.89 μg/mL and 98.09 ± 0.69 μg/mL respectively. Two known compounds β-sitosterol and lupeol were isolated from ethanolic extract of L. cephalotes leaves and were subjected to anti-hyperglycemic activity. Lupeol shows the best activity with IC50 55.73 ± 0.47 μg/mL and the results were verified by docking study of these compounds with mammalian α-amylase was carried out on its active site. It was concluded from the study that β-sitosterol and lupeol form one H-bond interactions with the active site residues either Asp212 or Thr21. The estimated free energy binding of β-sitosterol was found to be -9.47 kcal mol-1 with an estimated inhibition constant (Ki) of 558.94 nmol whereas the estimated free energy binding of lupeol was -11.73 kcal mol-1 with an estimated inhibition constant (Ki) of 476.71pmmol. The present study clearly showed that lupeol is more potent in comparison to β-sitosterol.

The high altitude results in lower ambient temperature, pressure, and density. Soaking at low temperature leads to higher oil viscosity, increasing the engine starter system torque requirement. Also, low temperature soaks results in a cold compressor rotor and casing. Since the thermal mass of rotor is higher than casing, casing expands faster, thereby, increasing the blade-casing tip clearance. The low pressure flow over the compressor blade coupled with the secondary flow through the compressor tip clearance during start result in stall inception. The present study discusses engine instrumentation required for capturing the stall inception event. The engine fan exit and combustion chamber were instrumented with dynamic pressure probes to capture the pressure characteristic and clamp-on current meter on primary igniter cable to capture ignition event during start cycle. The experiment was carried out at 10500 Ft. pressure altitude and -15°C ambient temperature.

In the present study, concentration of toxic heavy metals like zinc (Zn), cadmium (Cd), lead (Pb), nickel (Ni), cobalt (Co), chromium (Cr) and mercury (Hg) were determined in the tissues of tunas (<em>T. albacores</em>) caught from the area near to Lakshdweep Islands. The heavy metals are one of the indicators for the marine water pollution. Geochemical weathering, industrialization, agriculture run off, fishing, shipping and oil spills are the major pollutants. The presence of heavy toxic metals in the near coastal water fishes at both western coast and eastern coast of India has been well established. The present study was conducted assuming that the distant island will not have the metals presence in a way it is at the near main land coast. However, our study shows that there is a significant amount of the toxic metals present in the tissues of tuna samples. The gill, lever and flash samples were collected in waters around Lakshdweep Islands. They were analyzed using ICP–AES for the toxic metals after microwave digestion. The concentrations of the toxic metals were found in all fish samples and the general trend of presence was in decreasing order as Zn > Al > Cd > Pb > Cr > Ni > Hg. The amount of metals was found to higher in fish having more weight. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=toxic%20metals" title="toxic metals">toxic metals</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20tuna%20fish" title=" marine tuna fish"> marine tuna fish</a>, <a href="https://publications.waset.org/abstracts/search?q=bioaccumulation" title=" bioaccumulation"> bioaccumulation</a>, <a href="https://publications.waset.org/abstracts/search?q=biomagnifications" title=" biomagnifications"> biomagnifications</a> </p> <a href="https://publications.waset.org/abstracts/49209/assessment-of-heavy-metal-concentrations-in-tunas-caught-from-lakshweep-islands-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49209.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">355</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">30</span> Simulation of the Flow in Bilayer Coextrusion Dies with Gradually Changing Calibrator Profiles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahesh%20Gupta">Mahesh Gupta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main goal in the design of a die for extrusion of a complex profile is to obtain a uniform velocity at the die exit. If the velocity at the exit of an extrusion die is not uniform, the shape of the extrudate profile can change significantly after the polymer exits the die. To rectify the extrudate distortion caused by non-uniform exit velocity, calibrators and sizers are often installed along the extrudate cooling system. Furthermore, the profile shape in calibrators and sizers is sometimes gradually changed to intentionally deform the extrudate to the required final product shape. This is exploited to simplify extrusion die design, because a relatively simple profile at the die exit can be modified to obtain a more complex profile by deforming it in calibrators or sizers. The gradual change in the shape of calibrator or sizer profiles can also be used to extrude slightly different profiles from the same die. In the present work, a combined flow, thermal and structural analysis is used to accurately predict distortion of extrudate profile after the polymer leaves a die. Simulations of the flow and extrudate deformation in two different bilayer coextrusion dies with gradually changing profile shape in successive calibrators and sizers will be presented. The effect of non-uniform exit velocity, cooling shrinkage and shape of sizer profiles on extrudate deformation is included in the simulation. The predicted extrudate shape and layer structure is found to match accurately with those in a coextruded product. <p class="card-text"><strong>Keywords:</strong> <a
