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">407</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">128</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">127</span> Impact of Western Music Instruments on Indian Classical Music</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hukam%20Chand">Hukam Chand</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Over the past few years, the performance of Indian classical music has been improved a lot due to the technical inclusion of western instruments. Infect, the Indian classical music is all about raags which portray a mood and sentiments expressed through a microtonal scale based on natural harmonic series. And, most of the western instruments are not based on natural harmonic series and the tonal system is the only system which has considerable influence on the Indian classical music. However, the use of western instruments has been growing day by day in one way or the other by the Indian artists due to their quality of harmony. As a result of which, there are some common instruments such as harmonium, violin, guitar, saxophone, synthesizer which are being used commonly by Indian and western artists. On the other hand, a lot of fusion has taken place in the music of both sides due to the similar characteristics in their instruments. For example, harmonium which was originally the western instrument has now acquired an important position in Indian classical music to perform raags. Besides, a lot of suggestions for improving in the Indian music have been given by the artists for technical modification in the western instruments to cater the needs of Indian music through melody approach. Pt. Vishav Mohan Bhatt an Indian musician has developed Mohan Veena (called guitar) to perform raags. N. Rajam the Indian lady Violinist has made a remarkable work on Indian classical music by accompanied with vocal music. The purpose of the present research paper is to highlight the changes in Indian Classical Music through performance by using modified western music instruments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Indian%20classical%20music" title="Indian classical music">Indian classical music</a>, <a href="https://publications.waset.org/abstracts/search?q=Western%20instruments" title=" Western instruments"> Western instruments</a>, <a href="https://publications.waset.org/abstracts/search?q=harmonium" title=" harmonium"> harmonium</a>, <a href="https://publications.waset.org/abstracts/search?q=guitar" title=" guitar"> guitar</a>, <a href="https://publications.waset.org/abstracts/search?q=Violin%20and%20impact" title=" Violin and impact"> Violin and impact</a> </p> <a href="https://publications.waset.org/abstracts/46996/impact-of-western-music-instruments-on-indian-classical-music" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46996.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">521</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">126</span> Phase Segregating and Complex Forming Pb Based (=X-Pb) Liquid Alloys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Indra%20Bahadur%20Bhandari">Indra Bahadur Bhandari</a>, <a href="https://publications.waset.org/abstracts/search?q=Narayan%20Panthi"> Narayan Panthi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ishwar%20Koirala"> Ishwar Koirala</a>, <a href="https://publications.waset.org/abstracts/search?q=Devendra%20Adhikari"> Devendra Adhikari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We have used a theoretical model based on the assumption of compound formation in binary alloys to study the thermodynamic, microscopic, and surface properties of Bi-Pb and In-Pb liquid alloys. A review of the phase diagrams for these alloys shows that one of the stable complexes for Bi-Pb liquid alloy is BiPb3; also, that InPb is a stable phase in liquid In-Pb alloys. Using the same interaction parameters that are fitted for the free energy of mixing, we have been able to compute the bulk and thermodynamic properties of the alloys. From our observations, we are able to show that the Bi-Pb liquid alloy exhibits compound formation over the whole concentration range and the In-Pb alloys undergo phase separation. With regards to surface properties, Pb segregates more to the surface in In-Pb alloys than in Bi-Pb alloys. The viscosity isotherms have a positive deviation from ideality for both Bi-Pb and In-Pb alloys. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetry" title="asymmetry">asymmetry</a>, <a href="https://publications.waset.org/abstracts/search?q=Bi-Pb" title=" Bi-Pb"> Bi-Pb</a>, <a href="https://publications.waset.org/abstracts/search?q=deviation" title=" deviation"> deviation</a>, <a href="https://publications.waset.org/abstracts/search?q=In-Pb" title=" In-Pb"> In-Pb</a>, <a href="https://publications.waset.org/abstracts/search?q=interaction%20parameters" title=" interaction parameters"> interaction parameters</a> </p> <a href="https://publications.waset.org/abstracts/136406/phase-segregating-and-complex-forming-pb-based-x-pb-liquid-alloys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136406.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">160</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">125</span> Wet Chemical Synthesis for Fe-Ni Alloy Nanocrystalline Powder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neera%20Singh">Neera Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Devendra%20Kumar"> Devendra Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Om%20Parkash"> Om Parkash</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We have synthesized nanocrystalline Fe-Ni alloy powders where Ni varies as 10, 30 and 50 mole% by a wet chemical route (sol-gel auto-combustion) followed by reduction in hydrogen atmosphere. The ratio of citrate to nitrate was maintained at 0.3 where citric acid has worked as a fuel during combustion. The reduction of combusted powders was done at 700°C/1h in hydrogen atmosphere using an atmosphere controlled quartz tube furnace. Phase and microstructure analysis has shown the formation of α-(Fe,Ni) and γ-(Fe,Ni) phases after reduction. An increase in Ni concentration resulted in more γ-(Fe,Ni) formation where complete γ-(Fe,Ni) formation was achieved at 50 mole% Ni concentration. Formation of particles below 50 nm size range was confirmed using Scherrer’s formula and Transmission Electron Microscope. The work is aimed at the effect of Ni concentration on phase, microstructure and magnetic properties of synthesized alloy powders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=combustion" title="combustion">combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocrystalline" title=" nanocrystalline"> nanocrystalline</a>, <a href="https://publications.waset.org/abstracts/search?q=reduction" title=" reduction"> reduction</a> </p> <a href="https://publications.waset.org/abstracts/96277/wet-chemical-synthesis-for-fe-ni-alloy-nanocrystalline-powder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96277.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">181</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">124</span> Common Orthodontic Indices and Classification in the United Kingdom</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashwini%20Mohan">Ashwini Mohan</a>, <a href="https://publications.waset.org/abstracts/search?q=Haris%20Batley"> Haris Batley</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An orthodontic index is used to rate or categorise an individual’s occlusion using a numeric or alphanumeric score.

AM seems to be the most efficient way when compared to the traditional machining procedures. Still many problems continue to hinder its progress to becoming the most widely used of all. This paper contributes to the better understanding of AM and also aims at providing viable solutions to these problems, which may further help in enabling AM to become the most flaw free production method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing%20%28AM%29" title="additive manufacturing (AM)">additive manufacturing (AM)</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20printing" title=" 3D printing"> 3D printing</a>, <a href="https://publications.waset.org/abstracts/search?q=prototype" title=" prototype"> prototype</a>, <a href="https://publications.waset.org/abstracts/search?q=laser%20sintering" title=" laser sintering"> laser sintering</a> </p> <a href="https://publications.waset.org/abstracts/44548/laser-additive-manufacturing-a-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44548.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">380</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">120</span> Valorization of Marine Seaweed Biomass: Furanic Platform Chemicals and Beyond</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sanjay%20Kumar">Sanjay Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Saikat%20Dutta"> Saikat Dutta</a>, <a href="https://publications.waset.org/abstracts/search?q=Devendra%20S.%20Rawat"> Devendra S.

However, strain identification in terms of fuel productivity and over all economics of fuel generation remains a debatable challenge. Utilization of marine biomass, especially the ones important in the Indian subcontinent, in forming furanic fuels and specialty chemicals would likely to be a better value-addition pathway. Seaweed species e.g. Ulva, Sarconema, and Gracilaria species have been found more productive than land-based biomass sources due to their higher growth rate. Additionally, non-recalcitrant nature of marine biomass unlike lignocellulosics has attracted much attention in recent years towards producing bioethanol. Here we report the production of renewable, biomass-derived platform molecules such as furfural and 5-(chloromethyl) furfural (CMF) from a seaweed species which are abundant marine biomass. These products have high potential for synthetic upgradation into various classes of value-added compounds such as fuels, fuel-additives, and monomers for polymers, solvents, agrochemicals, and pharmaceuticals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seaweeds" title="seaweeds">seaweeds</a>, <a href="https://publications.waset.org/abstracts/search?q=Ulva" title=" Ulva"> Ulva</a>, <a href="https://publications.waset.org/abstracts/search?q=CMF" title=" CMF"> CMF</a>, <a href="https://publications.waset.org/abstracts/search?q=furan" title=" furan"> furan</a> </p> <a href="https://publications.waset.org/abstracts/57159/valorization-of-marine-seaweed-biomass-furanic-platform-chemicals-and-beyond" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57159.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">454</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">119</span> Tribological Behavior of Warm Rolled Spray Formed Al-6Si-1Mg-1Graphite Composite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Surendra%20Kumar%20Chourasiya">Surendra Kumar Chourasiya</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandeep%20Kumar"> Sandeep Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Devendra%20Singh"> Devendra Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present investigation tribological behavior of Al-6Si-1Mg-1Graphite composite has been explained. The composite was developed through the unique spray forming route in the spray forming chamber by using N₂ gas at 7kg/cm² and the flight distance was 400 mm. Spray formed composite having a certain amount of porosity which was reduced by the deformations. The composite was subjected to the warm rolling (WR) at 250ºC up to 40% reduction. Spray forming composite shows the considerable microstructure refinement, equiaxed grains, distribution of silicon and graphite particles in the primary matrix of the composite. Graphite (Gr) was incorporated externally during the process that works as a solid lubricant. Porosity decreased after reduction and hardness increases. Pin on disc test has been performed to analyze the wear behavior which is the function of sliding distance for all percent reduction of the composite. 30% WR composite shows the better result of wear rate and coefficient of friction. The improved wear properties of the composite containing Gr are discussed in light of the microstructural features of spray formed the composite and the nature of the debris particles. Scanning electron microscope and optical microscope analysis of the present material supported the prediction of aforementioned changes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Al-6Si-1Mg-1Graphite" title="Al-6Si-1Mg-1Graphite">Al-6Si-1Mg-1Graphite</a>, <a href="https://publications.waset.org/abstracts/search?q=spray%20forming" title=" spray forming"> spray forming</a>, <a href="https://publications.waset.org/abstracts/search?q=warm%20rolling" title=" warm rolling"> warm rolling</a>, <a href="https://publications.waset.org/abstracts/search?q=wear" title=" wear"> wear</a> </p> <a href="https://publications.waset.org/abstracts/77455/tribological-behavior-of-warm-rolled-spray-formed-al-6si-1mg-1graphite-composite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77455.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">565</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">118</span> Phytochemical Screening of Roots of Peltophorum pterocarpum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vidyadhar%20Suram">Vidyadhar Suram</a>, <a href="https://publications.waset.org/abstracts/search?q=D.%20Chamundeeswari"> D.

The meat industry has one of the highest consumption of water producing up to 10 times more polluted (BOD) wastewaters in comparison to domestic sewage. Therefore, suitable wastewater treatment methods are required to ensure the wastewater quality meet regulations before discharge. In the present study, a combined lab scale activated sludge-sonication system was used to treat pre-treated abattoir wastewater. A hydraulic retention time of 24 hours and a solid retention time of 13 days were used for the activated sludge process and using ultrasound as tertiary treatment. Different ultrasonic frequencies, powers and sonication times were applied to the samples and results were analysed for chemical oxygen demand (COD), biological oxygen demand (BOD), total suspended solids, pH, total coliforms and total viable counts. Additionally, both mechanical and chemical effects of ultrasound were quantified for organic matter removal (COD and BOD) and disinfection (microorganism inactivation) using different techniques such as aluminum foil pitting, flow cytometry, and KI dosimetry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abattoir%20wastewater" title="abattoir wastewater">abattoir wastewater</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater%20treatment" title=" wastewater treatment"> wastewater treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20disinfection" title=" water disinfection"> water disinfection</a> </p> <a href="https://publications.waset.org/abstracts/87214/a-combined-activated-sludge-sonication-process-for-abattoir-wastewater-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87214.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">287</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">115</span> Review of Suitable Advanced Oxidation Processes for Degradation of Organic Compounds in Produced Water during Enhanced Oil Recovery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Smita%20Krishnan">Smita Krishnan</a>, <a href="https://publications.waset.org/abstracts/search?q=Krittika%20Chandran"> Krittika Chandran</a>, <a href="https://publications.waset.org/abstracts/search?q=Chandra%20Mohan%20Sinnathambi"> Chandra Mohan Sinnathambi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Produced water and its treatment and management are growing challenges in all producing regions.

Another area of empirical research examined here is the opportunity recognition-venture creation sequence. While Malawi presents fruitful business opportunities, exploiting these opportunities into fully realized business ideas is a real challenge due to the country’s difficult business environment and poor promotional and marketing efforts.

The photoluminescence (PL) quantum yield (QY) of core-shell QDs increases with respect to the core, indicating that the radiative rate increases by the formation of shell around core, as evident by the measurement of PL lifetime. Further, the PL of bovine serum albumin is quenched strongly by the presence of core-shall QDs and follow the Stern-Volmer (S-V) relation, whereas the lifetime does not follow the S-V relation, demonstrating that the observed quenching is predominantly static in nature.

For the Total Suspended Solids (TSS), the average reduction increased to 99% in the same system, reducing the final value down to 3 mg/L. Additionally, 98% reduction in Phosphorus (P) and a complete inactivation of Total Coliforms (TC) was obtained after 17 min ozonation time. For Total Viable Counts (TVC), a drastic reduction was observed with 30 min ozonation time (6 log inactivation) at an ozone dose of 71 mg O3/L. Overall, the combined process was sufficient to meet discharge requirements without further treatment for the measured parameters (COD, BOD, TSS, P, TC, and TVC). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abattoir%20waste%20water" title="abattoir waste water">abattoir waste water</a>, <a href="https://publications.waset.org/abstracts/search?q=activated%20sludge" title=" activated sludge"> activated sludge</a>, <a href="https://publications.waset.org/abstracts/search?q=ozone" title=" ozone"> ozone</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20water%20treatment" title=" waste water treatment"> waste water treatment</a> </p> <a href="https://publications.waset.org/abstracts/82961/a-combined-activated-sludge-filtration-ozonation-process-for-abattoir-wastewater-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82961.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">109</span> A Review on the Use of Plastic Waste with Viable Materials in Composite Construction Block</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohan%20T.%20Harish">Mohan T.

Morphology, length, crystallite size, and crystallographic characterization of the grown nickel nanowires at an electrode distance of 20mm are presented. For this electrode distance of 20 mm, these two key electrodeposition factors when coupled was found to reduce crystallite size with a higher growth length and preferred orientation of Ni crystals. These observed changes can be inferred to be due to coupled interaction forces induced by the intensity of applied electric field (current density) and external magnetic field known as magnetohydrodynamic (MHD) effect during the electrodeposition process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anodic%20alumina%20oxide" title="anodic alumina oxide">anodic alumina oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=electrodeposition" title=" electrodeposition"> electrodeposition</a>, <a href="https://publications.waset.org/abstracts/search?q=nanowires" title=" nanowires"> nanowires</a>, <a href="https://publications.waset.org/abstracts/search?q=nickel" title=" nickel "> nickel </a> </p> <a href="https://publications.waset.org/abstracts/23704/structure-and-morphology-of-electrodeposited-nickel-nanowires-at-an-electrode-distance-of-20mm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23704.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">107</span> Application of Lean Manufacturing in Brake Shoe Manufacturing Plant: A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anees%20K.%20Ahamed">Anees K.

The layout was improved to reduce the movement of materials. It also quantifies the reduction in movement among the work stations. Value stream mapping has been used for identification of waste. Cause and effect diagram and 5W analysis are used to identify the reasons for defects and to provide the counter measures.

The disposal of spent catalyst falls under the category of hazardous industrial waste that requires strict agreement with environmental regulations. The spent hydroprocessing catalyst contains Mo, V and Ni at high concentrations that have been found to be economically significant for recovery. Metal recovery process includes deoiling, decoking, grinding, dissolving and treatment with complexing leaching agent such as ethylene diamine tetra acetic acid (EDTA). The process conditions have been optimized as a function of time, temperature and EDTA concentration in presence of ultrasonic agitation. The results indicated that optimum condition established through this approach could recover 97%, 94% and 95% of the extracted Mo, V and Ni, respectively, while 95% EDTA was recovered after acid treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atmospheric%20residue%20desulfurization%20%28ARDS%29" title="atmospheric residue desulfurization (ARDS)">atmospheric residue desulfurization (ARDS)</a>, <a href="https://publications.waset.org/abstracts/search?q=deactivation" title=" deactivation"> deactivation</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrotreating" title=" hydrotreating"> hydrotreating</a>, <a href="https://publications.waset.org/abstracts/search?q=spent%20catalyst" title=" spent catalyst"> spent catalyst</a> </p> <a href="https://publications.waset.org/abstracts/72632/refining-waste-spent-hydroprocessing-catalyst-and-their-metal-recovery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72632.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">323</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">105</span> Electronic Structure and Optical Properties of YNi₄Si-Type GdNi₅: A Coulomb Corrected Local-Spin Density Approximation Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sapan%20Mohan%20Saini">Sapan Mohan Saini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, we report the calculations on the electronic and optical properties of YNi₄Si-type GdNi₅ compound.

The Coulomb corrected local-spin density approximation (LSDA+U) in the self-interaction correction (SIC) has been used for exchange-correlation potential. Spin polarised calculations of band structure show that several bands cross the Fermi level (EF) reflect the metallic character. Analysis of density of states (DOS) demonstrates that spin up Gd-f states lie around 7.5 eV below EF and spin down Gd-f lie around 4.5 eV above EF. We found Ni-3d states mainly contribute to DOS from -5.0 eV to the EF.

The main issue in epidemiological affected regions is the presence of an asymptomatic individual that might potentially convert to a symptomatic visceral leishmaniasis (VL). The epidemiological study has been conducted at highly VL endemic Moriyama village in Patna district, Bihar, India that covers total population of 1540 individuals. Here, 1104(74.02%) people had been randomly screened and only 46 (4.17%) asymptomatic individuals were found sero-positive by the rK39 test. After taking signed informed consent form, blood samples were collected from 46 asymptomatic subjects for further hematological and immunological tests. Total leukocyte count, hemoglobin (gm%), neutrophil, lymphocyte, platelet count and interleukin-10 (IL-10) had been included as diagnostic markers. Interestingly only 5 (10.86%) individuals showed their asymptomatic conversion into symptomatic VL patients during quarterly surveillance. In overall analysis only two markers are suggestive for disease conversion that is hemoglobin (gm%) and IL-10. In all the infected patients, both the mean decrease in hemoglobin and mean increase of IL-10 was 19.23% from its normal value. The results might suggest that hematological and immunological changes would become helpful for early diagnosis of asymptomatic to symptomatic VL conversion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymptomatic" title="asymptomatic">asymptomatic</a>, <a href="https://publications.waset.org/abstracts/search?q=epidemiological" title=" epidemiological"> epidemiological</a>, <a href="https://publications.waset.org/abstracts/search?q=symptomatic%20visceral%20leishmaniasis" title=" symptomatic visceral leishmaniasis"> symptomatic visceral leishmaniasis</a>, <a href="https://publications.waset.org/abstracts/search?q=hemoglobin%20%28gm%25%29" title=" hemoglobin (gm%)"> hemoglobin (gm%)</a>, <a href="https://publications.waset.org/abstracts/search?q=interleukin-10" title=" interleukin-10"> interleukin-10</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnosis" title=" diagnosis"> diagnosis</a> </p> <a href="https://publications.waset.org/abstracts/99701/endeavor-to-develop-immunological-and-hematological-early-diagnostic-marker-to-check-the-conversion-of-asymptomatic-to-symptomatic-visceral-leishmaniasis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99701.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">209</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">102</span> Design, Synthesis and Evaluation of 4-(Phenylsulfonamido)Benzamide Derivatives as Selective Butyrylcholinesterase Inhibitors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sushil%20Kumar%20Singh">Sushil Kumar Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashok%20Kumar"> Ashok Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ankit%20%20Ganeshpurkar"> Ankit Ganeshpurkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ravi%20Singh"> Ravi Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Devendra%20Kumar"> Devendra Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In spectrum of neurodegenerative diseases, Alzheimer’s disease (AD) is characterized by the presence of amyloid β plaques and neurofibrillary tangles in the brain. It results in cognitive and memory impairment due to loss of cholinergic neurons, which is considered to be one of the contributing factors. Donepezil, an acetylcholinesterase (AChE) inhibitor which also inhibits butyrylcholinesterase (BuChE) and improves the memory and brain’s cognitive functions, is the most successful and prescribed drug to treat the symptoms of AD. The present work is based on designing of the selective BuChE inhibitors using computational techniques. In this work, machine learning models were trained using classification algorithms followed by screening of diverse chemical library of compounds. The various molecular modelling and simulation techniques were used to obtain the virtual hits. The amide derivatives of 4-(phenylsulfonamido) benzoic acid were synthesized and characterized using 1H & 13C NMR, FTIR and mass spectrometry. The enzyme inhibition assays were performed on equine plasma BuChE and electric eel’s AChE by method developed by Ellman et al. Compounds 31, 34, 37, 42, 49, 52 and 54 were found to be active against equine BuChE. N-(2-chlorophenyl)-4-(phenylsulfonamido)benzamide and N-(2-bromophenyl)-4-(phenylsulfonamido)benzamide (compounds 34 and 37) displayed IC50 of 61.32 ± 7.21 and 42.64 ± 2.17 nM against equine plasma BuChE. Ortho-substituted derivatives were more active against BuChE. Further, the ortho-halogen and ortho-alkyl substituted derivatives were found to be most active among all with minimal AChE inhibition. The compounds were selective toward BuChE. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alzheimer%20disease" title="Alzheimer disease">Alzheimer disease</a>, <a href="https://publications.waset.org/abstracts/search?q=butyrylcholinesterase" title=" butyrylcholinesterase"> butyrylcholinesterase</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=sulfonamides" title=" sulfonamides "> sulfonamides </a> </p> <a href="https://publications.waset.org/abstracts/122292/design-synthesis-and-evaluation-of-4-phenylsulfonamidobenzamide-derivatives-as-selective-butyrylcholinesterase-inhibitors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122292.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">139</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">101</span> Magnetic Cellulase/Halloysite Nanotubes as Biocatalytic System for Converting Agro-Waste into Value-Added Product</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Devendra%20Sillu">Devendra Sillu</a>, <a href="https://publications.waset.org/abstracts/search?q=Shekhar%20Agnihotri"> Shekhar Agnihotri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The 'nano-biocatalyst' utilizes an ordered assembling of enzyme on to nanomaterial carriers to catalyze desirable biochemical kinetics and substrate selectivity. The current study describes an inter-disciplinary approach for converting agriculture waste, sugarcane bagasse into D-glucose exploiting halloysite nanotubes (HNTs) decorated cellulase enzyme as nano-biocatalytic system. Cellulase was successfully immobilized on HNTs employing polydopamine as an eco-friendly crosslinker while iron oxide nanoparticles were attached to facilitate magnetic recovery of material. The characterization studies (UV-Vis, TEM, SEM, and XRD) displayed the characteristic features of both cellulase and magnetic HNTs in the resulting nanocomposite. Various factors (i.e., working pH, temp., crosslinker conc., enzyme conc.) which may influence the activity of biocatalytic system were investigated. The experimental design was performed using Response Surface Methodology (RSM) for process optimization. Analyses data demonstrated that the nanobiocatalysts retained 80.30% activity even at elevated temperature (55°C) and excellent storage stabilities after 10 days. The repeated usage of system revealed a remarkable consistent relative activity over several cycles. The immobilized cellulase was employed to decompose agro-waste and the maximum decomposition rate of 67.2 % was achieved. Conclusively, magnetic HNTs can serve as a potential support for enzyme immobilization with long term usage, good efficacy, reusability and easy recovery from solution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=halloysite%20nanotubes" title="halloysite nanotubes">halloysite nanotubes</a>, <a href="https://publications.waset.org/abstracts/search?q=enzyme%20immobilization" title=" enzyme immobilization"> enzyme immobilization</a>, <a href="https://publications.waset.org/abstracts/search?q=cellulase" title=" cellulase"> cellulase</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20surface%20methodology" title=" response surface methodology"> response surface methodology</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20recovery" title=" magnetic recovery"> magnetic recovery</a> </p> <a href="https://publications.waset.org/abstracts/98924/magnetic-cellulasehalloysite-nanotubes-as-biocatalytic-system-for-converting-agro-waste-into-value-added-product" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98924.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">133</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">100</span> Effect of Sulfur Content on Fatigue Strength of AISI 4140 Steel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sachin%20S.%20Patil">Sachin S.

In present work, the effect of sulfur content and its inclusions on the fatigue behavior of AISI 4140 steel is studied (sulfur content 0.002% and 0.016%). Metallurgical analysis, Mechanical testing and Rotating Bending Fatigue (RBF) test were carried out. With the increase in sulfur content, ductility and toughness of the material decrease significantly and large scatter is observed in UTS and impact energy values. From the results of RBF testing, it can be observed that increase in sulfur content from 0.002% to 0.016% has a negligible effect on the endurance strength of AISI 4140 for similar hardness level. Fractography analysis was carried out to study the failure modes in testing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AISI%204140"
