The nanostructure of carbon fibers offers enhanced properties of conductivity due to the larger surface area. The next generation carbon nanofibers demand the porous structure as it offers more surface area. Multiple techniques are used to produce carbon fibers. However, electrospinning followed by carbonization of the polymeric materials is easy to carry process on a laboratory scale. Also, it offers multiple diversity of changing parameters to acquire the desired properties of carbon fibers. Polyacrylonitrile (PAN) is the most used material for the production of carbon fibers due to its promising processing parameters. Also, cellulose is one of the highest yield producers of carbon fibers. However, the electrospinning of cellulosic materials is difficult due to its rigid chain structure. The combination of PAN and cellulose can offer a suitable solution for the production of carbon fibers. Both materials are miscible in the mixed solvent of N, N, Dimethylacetamide and lithium chloride. This study focuses on the production of porous carbon fibers as a function of PAN/Cellulose blend ratio, solution properties, and electrospinning parameters. These single polymer and blend with different ratios were electrospun to give fine fibers. The higher amount of cellulose offered more difficulty in electrospinning of nanofibers. After carbonization, the carbon fibers were studied in terms of their blend ratio, surface area, and texture. Cellulose contents offered the porous structure of carbon fibers. Also, the presence of LiCl contributed to the porous structure of carbon fibers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cellulose" title="cellulose">cellulose</a>, <a href="https://publications.waset.org/abstracts/search?q=polyacrylonitrile" title=" polyacrylonitrile"> polyacrylonitrile</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanofibers" title=" carbon nanofibers"> carbon nanofibers</a>, <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title=" electrospinning"> electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=blend" title=" blend"> blend</a> </p> <a href="https://publications.waset.org/abstracts/93471/development-of-electrospun-porous-carbon-fibers-from-cellulosepolyacrylonitrile-blend" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93471.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">202</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">69</span> Pain Management in Burn Wounds with Dual Drug Loaded Double Layered Nano-Fiber Based Dressing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sharjeel%20Abid">Sharjeel Abid</a>, <a href="https://publications.waset.org/abstracts/search?q=Tanveer%20Hussain"> Tanveer Hussain</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahsan%20Nazir"> Ahsan Nazir</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Zahir"> Abdul Zahir</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabyl%20Khenoussi"> Nabyl Khenoussi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Localized application of drug has various advantages and fewer side effects as compared with other methods. Burn patients suffer from swear pain and the major aspects that are considered for burn victims include pain and infection management. Nano-fibers (NFs) loaded with drug, applied on local wound area, can solve these problems. Therefore, this study dealt with the fabrication of drug loaded NFs for better pain management. Two layers of NFs were fabricated with different drugs. Contact layer was loaded with Gabapentin (a nerve painkiller) and the second layer with acetaminophen. The fabricated dressing was characterized using scanning electron microscope, Fourier Transform Infrared Spectroscopy, X-Ray Diffraction and UV-Vis Spectroscopy. The double layered based NFs dressing was designed to have both initial burst release followed by slow release to cope with pain for two days. The fabricated nanofibers showed diameter < 300 nm. The liquid absorption capacity of the NFs was also checked to deal with the exudate. The fabricated double layered dressing with dual drug loading and release showed promising results that could be used for dealing pain in burn victims. It was observed that by the addition of drug, the size of nanofibers was reduced, on the other hand, the crystallinity %age was increased, and liquid absorption decreased. The combination of fast nerve pain killer release followed by slow release of non-steroidal anti-inflammatory drug could be a good tool to reduce pain in a more secure manner with fewer side effects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pain%20management" title="pain management">pain management</a>, <a href="https://publications.waset.org/abstracts/search?q=burn%20wounds" title=" burn wounds"> burn wounds</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-fibers" title=" nano-fibers"> nano-fibers</a>, <a href="https://publications.waset.org/abstracts/search?q=controlled%20drug%20release" title=" controlled drug release"> controlled drug release</a> </p> <a href="https://publications.waset.org/abstracts/94600/pain-management-in-burn-wounds-with-dual-drug-loaded-double-layered-nano-fiber-based-dressing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94600.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">68</span> Synthesis of Iron Oxide Doped Zeolite: An Antimicrobial Nanomaterial for Drinking Water Purification Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Zeeshan">Muhammad Zeeshan</a>, <a href="https://publications.waset.org/abstracts/search?q=Rabia%20Nazir"> Rabia Nazir</a>, <a href="https://publications.waset.org/abstracts/search?q=Lubna%20Tahir"> Lubna Tahir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Low cost filter based on iron doped zeolite (Fe-Z) and pottery clay was developed for an effective and efficient treatment of the drinking water contaminated with microbes.

The observed soil mass losses for the confined soil systems were much smaller than those from unconfined system. As a result, the size of confinement and rainfall intensity have a direct effect on the soil mass loss. The triangular and rectangular confinement systems showed the lowest and highest soil loss masses, respectively.

Three models were formulated based on diffusion process using Fick’s principle and the law of mass action. The rate constants governing the law of mass action were used on the basis of the drug efficacy at different interfaces. The Laplace transform and eigenvalue methods were used to obtain the solution of the ordinary differential equations concerning the rate of change of concentration in different compartments viz. blood and tissue medium. The drug concentration in the different compartments has been computed using numerical parameters. The results illustrate the variation of drug concentration with respect to time using MATLAB software. It has been observed from the results that the drug concentration decreases in the first compartment and gradually increases in other subsequent compartments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laplace%20transform" title="Laplace transform">Laplace transform</a>, <a href="https://publications.waset.org/abstracts/search?q=diffusion" title=" diffusion"> diffusion</a>, <a href="https://publications.waset.org/abstracts/search?q=eigenvalue%20method" title=" eigenvalue method"> eigenvalue method</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20model" title=" mathematical model"> mathematical model</a> </p> <a href="https://publications.waset.org/abstracts/43080/mathematical-models-for-drug-diffusion-through-the-compartments-of-blood-and-tissue-medium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43080.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">334</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">63</span> A Software Product Engineering Process for Commercial Success in Start-Up and Cases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Javed%20Ahsan">Javed Ahsan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Software engineers strive for technical sophistication with a dream of finding commercial success in their start-up business.

Results of linear regression analysis reveals that high perception of meaning in life will lead to high psychological well-being and low stress among university students. Non-significant differences are found on meaning in life variable with regard to gender in the sample using t-test. Together these results suggest that meaning in life independent of gender, is a significant predictor of the levels of stress and psychological well-being being directly related to psychological well-being and inversely related to stress levels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=existential%20meaning%20in%20life" title="existential meaning in life">existential meaning in life</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20well-being" title=" psychological well-being"> psychological well-being</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a>, <a href="https://publications.waset.org/abstracts/search?q=students" title=" students"> students</a> </p> <a href="https://publications.waset.org/abstracts/2541/impact-of-meaning-in-life-on-stress-and-psychological-well-being" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2541.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">506</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">61</span> Data Analysis to Uncover Terrorist Attacks Using Data Mining Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saima%20Nazir">Saima Nazir</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustansar%20Ali%20Ghazanfar"> Mustansar Ali Ghazanfar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanay%20Muhammad%20Umar%20Saeed"> Sanay Muhammad Umar Saeed</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Awais%20Azam"> Muhammad Awais Azam</a>, <a href="https://publications.waset.org/abstracts/search?q=Saad%20Ali%20Alahmari"> Saad Ali Alahmari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Terrorism is an important and challenging concern. The entire world is threatened by only few sophisticated terrorist groups and especially in Gulf Region and Pakistan, it has become extremely destructive phenomena in recent years. Predicting the pattern of attack type, attack group and target type is an intricate task. This study offers new insight on terrorist group’s attack type and its chosen target. This research paper proposes a framework for prediction of terrorist attacks using the historical data and making an association between terrorist group, their attack type and target. Analysis shows that the number of attacks per year will keep on increasing, and Al-Harmayan in Saudi Arabia, Al-Qai’da in Gulf Region and Tehreek-e-Taliban in Pakistan will remain responsible for many future terrorist attacks. Top main targets of each group will be private citizen & property, police, government and military sector under constant circumstances. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20mining" title="data mining">data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=counter%20terrorism" title=" counter terrorism"> counter terrorism</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=SVM" title=" SVM"> SVM</a> </p> <a href="https://publications.waset.org/abstracts/59817/data-analysis-to-uncover-terrorist-attacks-using-data-mining-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59817.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">409</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">60</span> Environmental Impact of Gas Field Decommissioning </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ahsan">Muhammad Ahsan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effective decommissioning of oil and gas fields and related assets is one of the most important challenges facing the oil and gas industry today and in the future. Decommissioning decisions can no longer be avoided by the operators and the industry as a whole. Decommissioning yields no return on investment and carries significant regulatory liabilities. The main objective of this paper is to provide an approach and mechanism for the estimation of emissions associated with decommissioning of Oil and Gas fields. The model uses gate to gate approach and considers field life from development phase up to asset end life. The model incorporates decommissioning processes which includes; well plugging, plant dismantling, wellhead, and pipeline dismantling, cutting and temporary fabrication, new manufacturing from raw material and recycling of metals. The results of the GHG emissions during decommissioning phase are 2.31x10-2 Kg CO2 Eq. per Mcf of the produced natural gas. Well plug and abandonment evolved to be the most GHG emitting activity with 84.7% of total field decommissioning operational emissions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LCA%20%28life%20cycle%20analysis%29" title="LCA (life cycle analysis)">LCA (life cycle analysis)</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20field" title=" gas field"> gas field</a>, <a href="https://publications.waset.org/abstracts/search?q=decommissioning" title=" decommissioning"> decommissioning</a>, <a href="https://publications.waset.org/abstracts/search?q=emissions" title=" emissions"> emissions</a> </p> <a href="https://publications.waset.org/abstracts/83123/environmental-impact-of-gas-field-decommissioning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83123.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">186</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">59</span> Collision Induced Dissociation of Transition Metal Fluoride Complexes and the Multiply Charged Anions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ruqia%20Nazir">Ruqia Nazir</a>, <a href="https://publications.waset.org/abstracts/search?q=Robin%20Perutz"> Robin Perutz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Collision-induced dissociation (CID) can be used to study the intrinsic properties of ions in the gas phase.1 Decay pathways of transition metal difluoride complexes of titanium, zirconium, hafnium, and ruthenium were studied by CID in an ESI-Ion trap mass spectrometer. Furthermore, the decay pathways of multiply charged anions (MCAs) of titanium and zirconium were also studied. The CID results are illustrated by the behaviour of (Cp*)₂TiF₂, which initially forms the ions [M-F-]⁺, [M+Na]⁺, and [M+K]⁺. The [(Cp*₂)TiF⁺ ion decays on resonant excitation to lose HF forming [Cp*(C₅Me₄CH₂)Ti]⁺ (Figure). The other major ion, [(Cp*)₂TiF₂+Na]⁺, decays on resonant excitation with production of [(Cp*)₂TiF₂]⁺ and [C₅Me₄CH₂]⁺. We also report the behaviour of Cp₂MF₂ (M = Zr, Hf) and Ru(PMe₃)₄F₂. The decay pathway of the multiply charged anions (MCAs), notably TiF₆²⁻ and ZrF₆²⁻ was concluded to be ionic fragmentation with loss of F⁻ rather than electron detachment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collision%20induced%20dissociation" title="collision induced dissociation">collision induced dissociation</a>, <a href="https://publications.waset.org/abstracts/search?q=transition%20metal%20difluoride%20comolexes" title=" transition metal difluoride comolexes"> transition metal difluoride comolexes</a>, <a href="https://publications.waset.org/abstracts/search?q=multiply%20charged%20anions" title=" multiply charged anions"> multiply charged anions</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20spectrometry" title=" mass spectrometry"> mass spectrometry</a> </p> <a href="https://publications.waset.org/abstracts/156008/collision-induced-dissociation-of-transition-metal-fluoride-complexes-and-the-multiply-charged-anions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156008.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">107</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">58</span> Winged Test Rocket with Fully Autonomous Guidance and Control for Realizing Reusable Suborbital Vehicle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Koichi%20Yonemoto">Koichi Yonemoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Yamasaki"> Hiroshi Yamasaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Masatomo%20Ichige"> Masatomo Ichige</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuke%20Ura"> Yusuke Ura</a>, <a href="https://publications.waset.org/abstracts/search?q=Guna%20S.%20Gossamsetti"> Guna S.

The mathematical terminologies of nano concentration, velocity and temperature are first cast into dimensionless expressions via suitable conversions and then solved by using Shooting technique to obtain the numerical solutions. Graphs has been plotted to check the convergence of constructed solutions. At the end, the influence of effective parameters on nanoparticle concentration, velocity and temperature fields are also deliberated in a comprehensive way. Moreover, the physical measures of engineering importance such as the Sherwood number, Skin friction and Nusselt number are also calculated. It is perceived that the thermal radiation enhances the temperature for both Vogel's and Reynolds' models but the normal stress parameter causes a reduction in temperature profile. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MHD%20flow" title="MHD flow">MHD flow</a>, <a href="https://publications.waset.org/abstracts/search?q=differential%20type%20nanofluid" title=" differential type nanofluid"> differential type nanofluid</a>, <a href="https://publications.waset.org/abstracts/search?q=Porous%20medium" title=" Porous medium"> Porous medium</a>, <a href="https://publications.waset.org/abstracts/search?q=variable%20viscosity" title=" variable viscosity"> variable viscosity</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20radiation" title=" thermal radiation"> thermal radiation</a> </p> <a href="https://publications.waset.org/abstracts/89385/a-prospective-evaluation-of-thermal-radiation-effects-on-magneto-hydrodynamic-transport-of-a-nanofluid-traversing-a-spongy-medium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89385.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">243</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">55</span> Study of Some Epidemiological Factors Influencing the Disease Incidence in Chickpea (Cicer Arietinum L.)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Asim%20Nazir">Muhammad Asim Nazir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The investigations reported in this manuscript were carried on the screening of one hundred and seventy-eight chickpea germplasm lines/cultivars against wilt disease, caused by Fusarium oxysporum f. sp. ciceris. The screening was conducted in vivo (field) conditions. The field screening was accompanied with the study of some epidemiological factors affecting the occurrence and severity of the disease. Among the epidemiological factors maximum temperature range (28-40°C), minimum temperature range (12-24°C), relative humidity (19-44%), soil temperature (26-41°C) and soil moisture range (19-34°C) was studied for affecting the disease incidence/severity. The results revealed that air temperature was positively correlated with diseases. Soil temperature data revealed that in all cultivars disease incidence was maximum as 39°C. Most of the plants show 40-50% disease incidence. Disease incidence decreased at 33.5°C. The result of correlation of relative humidity of air and wilt incidence revealed that all cultivars/lines were negatively correlated with relative humidity. With increasing relative humidity wilt incidence decreased and vice versa. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chickpea" title="chickpea">chickpea</a>, <a href="https://publications.waset.org/abstracts/search?q=epidemiological" title=" epidemiological"> epidemiological</a>, <a href="https://publications.waset.org/abstracts/search?q=screening" title=" screening"> screening</a>, <a href="https://publications.waset.org/abstracts/search?q=disease" title=" disease"> disease</a> </p> <a href="https://publications.waset.org/abstracts/19669/study-of-some-epidemiological-factors-influencing-the-disease-incidence-in-chickpea-cicer-arietinum-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19669.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">641</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">54</span> Safety Factors for Improvement of Labor's Health and Safety in Construction Industry of Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahsan%20Ali%20Khan">Ahsan Ali Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During past few years, researchers are emphasizing more on the need of safety in construction industry. This need of safety is an important issue in developing countries. As due to development they are facing huge construction growth. This research is done to evaluate labor safety condition in construction industry of Pakistan. The research carried out through questionnaire survey at different construction sites. Useful data are gathered from these sites which then factor analyzed resulting in five factors. These factors reflect that most of the workers are aware of the safety need, but they divert this responsibility towards management and claim that the work is more essential for management instead of safety. Moreover, those work force which is unaware of safety state that there is lack of any training and guidance from upper management which lead to many unfavorable events on construction sites. There is need of implementation safety activities by management like training, formulation of rules and policies. This research will be helpful to divert management attention towards safety need so they will make efforts for safety of their manpower—the workers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=labor%27s%20safety" title="labor's safety">labor's safety</a>, <a href="https://publications.waset.org/abstracts/search?q=management%20role" title=" management role"> management role</a>, <a href="https://publications.waset.org/abstracts/search?q=Pakistan" title=" Pakistan"> Pakistan</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20factors" title=" safety factors"> safety factors</a> </p> <a href="https://publications.waset.org/abstracts/99432/safety-factors-for-improvement-of-labors-health-and-safety-in-construction-industry-of-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99432.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">191</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">53</span> Antecedents of Knowledge Sharing: Investigating the Influence of Knowledge Sharing Factors towards Postgraduate Research Supervision</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arash%20Khosravi">Arash Khosravi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Nazir%20Ahmad"> Mohamad Nazir Ahmad </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today’s economy is a knowledge-based economy in which knowledge is a crucial facilitator to individuals, as well as being an instigator of success. Due to the impact of globalization, universities face new challenges and opportunities. Accordingly, they ought to be more innovative and have their own competitive advantages. One of the most important goals of universities is the promotion of students as professional knowledge workers. Therefore, knowledge sharing and transferring at tertiary level between students and supervisors is vital in universities, as it decreases the budget and provides an affordable way of doing research. Knowledge-sharing impact factors can be categorized into three groups, namely: organizational, individual and technical factors. There are some individual barriers to knowledge sharing, namely: lack of time and trust, lack of communication skills and social networks. IT systems such as e-learning, blogs and portals can increase knowledge sharing capability. However, it must be stated that IT systems are only tools and not solutions. Individuals are still responsible for sharing information and knowledge. This paper proposes new research model to examine the effect of individual factors and organisational factors, namely: learning strategy, trust culture, supervisory support, as well as technological factor on knowledge sharing in a research supervision process at the University of Technology Malaysia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knowledge%20management" title="knowledge management">knowledge management</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20sharing" title=" knowledge sharing"> knowledge sharing</a>, <a href="https://publications.waset.org/abstracts/search?q=research%20supervision" title=" research supervision"> research supervision</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20transferring" title=" knowledge transferring"> knowledge transferring</a> </p> <a href="https://publications.waset.org/abstracts/7312/antecedents-of-knowledge-sharing-investigating-the-influence-of-knowledge-sharing-factors-towards-postgraduate-research-supervision" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7312.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">445</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">52</span> Model Based Fault Diagnostic Approach for Limit Switches</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zafar%20Mahmood">Zafar Mahmood</a>, <a href="https://publications.waset.org/abstracts/search?q=Surayya%20Naz"> Surayya Naz</a>, <a href="https://publications.waset.org/abstracts/search?q=Nazir%20Shah%20Khattak"> Nazir Shah Khattak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The degree of freedom relates to our capability to observe or model the energy paths within the system. Higher the number of energy paths being modeled leaves to us a higher degree of freedom, but increasing the time and modeling complexity rendering it useless for today’s world’s need for minimum time to market. Since the number of residuals that can be uniquely isolated are dependent on the number of independent outputs of the system, increasing the number of sensors required. The examples of discrete position sensors that may be used to form an array include limit switches, Hall effect sensors, optical sensors, magnetic sensors, etc. Their mechanical design can usually be tailored to fit in the transitional path of an STME in a variety of mechanical configurations. The case studies into multi-sensor system were carried out and actual data from sensors is used to test this generic framework. It is being investigated, how the proper modeling of limit switches as timing sensors, could lead to unified and neutral residual space while keeping the implementation cost reasonably low. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low-cost%20limit%20sensors" title="low-cost limit sensors">low-cost limit sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=fault%20diagnostics" title=" fault diagnostics"> fault diagnostics</a>, <a href="https://publications.waset.org/abstracts/search?q=Single%20Throw%20Mechanical%20Equipment%20%28STME%29" title=" Single Throw Mechanical Equipment (STME)"> Single Throw Mechanical Equipment (STME)</a>, <a href="https://publications.waset.org/abstracts/search?q=parameter%20estimation" title=" parameter estimation"> parameter estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=parity-space" title=" parity-space"> parity-space</a> </p> <a href="https://publications.waset.org/abstracts/25825/model-based-fault-diagnostic-approach-for-limit-switches" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25825.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">617</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">51</span> Exhaustive Study of Essential Constraint Satisfaction Problem Techniques Based on N-Queens Problem</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Md.%20Ahsan%20Ayub">Md.

In our exhaustive study, it has been possible to visualize the processes of essential CSP algorithms from a very concrete constraint satisfaction example, NQueens Problem, in order to possess a deep understanding about how a particular constraint satisfaction problem will be dealt with by our studied and implemented techniques. Besides, benchmark results - time vs. value of N in N-Queens - have been generated from our implemented approaches, which help understand at what factor each algorithm produces solutions; especially, in N-Queens puzzle. Thus, extended decisions can be made to instantiate a real life problem within CSP’s framework. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arc%20consistency%20%28AC%29" title="arc consistency (AC)">arc consistency (AC)</a>, <a href="https://publications.waset.org/abstracts/search?q=backjumping%20algorithm%20%28BJ%29" title=" backjumping algorithm (BJ)"> backjumping algorithm (BJ)</a>, <a href="https://publications.waset.org/abstracts/search?q=backtracking%20algorithm%20%28BT%29" title=" backtracking algorithm (BT)"> backtracking algorithm (BT)</a>, <a href="https://publications.waset.org/abstracts/search?q=constraint%20satisfaction%20problem%20%28CSP%29" title=" constraint satisfaction problem (CSP)"> constraint satisfaction problem (CSP)</a>, <a href="https://publications.waset.org/abstracts/search?q=forward%20checking%20%28FC%29" title=" forward checking (FC)"> forward checking (FC)</a>, <a href="https://publications.waset.org/abstracts/search?q=least%20constrained%20values%20%28LCV%29" title=" least constrained values (LCV)"> least constrained values (LCV)</a>, <a href="https://publications.waset.org/abstracts/search?q=maintaining%20arc%20consistency%20%28MAC%29" title=" maintaining arc consistency (MAC)"> maintaining arc consistency (MAC)</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20remaining%20values%20%28MRV%29" title=" minimum remaining values (MRV)"> minimum remaining values (MRV)</a>, <a href="https://publications.waset.org/abstracts/search?q=N-Queens%20problem" title=" N-Queens problem"> N-Queens problem</a> </p> <a href="https://publications.waset.org/abstracts/69933/exhaustive-study-of-essential-constraint-satisfaction-problem-techniques-based-on-n-queens-problem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69933.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">50</span> A Qualitative Study on Metacognitive Patterns among High and Low Performance Problem Based on Learning Groups</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zuhairah%20Abdul%20Hadi">Zuhairah Abdul Hadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Nazir%20bin%20Md.%20Zabit"> Mohd Nazir bin Md.

Expert learners engage in metacognition by monitoring and controlling their thinking, and listing, considering and selecting the best strategies to achieve desired goals. Studies also found that good critical thinkers engage in more metacognition and people tend to activate more metacognition when solving complex problems. This study extends past studies by performing a qualitative analysis to understand metacognitive patterns among two high and two low performing groups by carefully examining video and audio records taken during Problem-based learning activities. High performing groups are groups with majority members scored well in Watson Glaser II Critical Thinking Appraisal (WGCTA II) and academic achievement tests. Low performing groups are groups with majority members fail to perform in the two tests. Audio records are transcribed and analyzed using schemas adopted from past studies. Metacognitive statements are analyzed using three stages model and patterns of metacognitive are described by contexts, components, and levels for each high and low performing groups. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=academic%20achievement" title="academic achievement">academic achievement</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20thinking" title=" critical thinking"> critical thinking</a>, <a href="https://publications.waset.org/abstracts/search?q=metacognitive" title=" metacognitive"> metacognitive</a>, <a href="https://publications.waset.org/abstracts/search?q=problem-based%20learning" title=" problem-based learning"> problem-based learning</a> </p> <a href="https://publications.waset.org/abstracts/83924/a-qualitative-study-on-metacognitive-patterns-among-high-and-low-performance-problem-based-on-learning-groups" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83924.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">284</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> [Keynote Speech]: Guiding Teachers to Make Lessons Relevant, Appealing, and Personal (RAP) for Academically-Low-Achieving Students in STEM Subjects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nazir%20Amir">Nazir Amir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Teaching approaches to present science and mathematics content amongst academically-low-achieving students may need to be different than approaches that are adopted for the more academically-inclined students, primarily due to the different learning needs and learning styles of these students. In crafting out lessons to motivate and engage these students, teachers need to consider the backgrounds of these students and have a good understanding of their interests so that lessons can be presented in ways that appeal to them, and made relevant not just to the world around them, but also to their personal experiences. This presentation highlights how the author worked with a Professional Learning Community (PLC) of teachers in crafting out fun and feasible classroom teaching approaches to present science and mathematics content in ways that are made Relevant, Appealing, and Personal (RAP) to groups of academically-low-achieving students in Singapore. Feedback from the students and observations from their work suggest that they were engaged through the RAP-modes of instruction, and were able to appreciate the role of science and mathematics through a variety of low-cost design-based STEM (Science, Technology, Engineering, and Mathematics) activities. Such results imply that teachers teaching academically-low-achieving students, and those in under-resourced communities, could consider infusing RAP-infused instructions into their lessons in getting students develop positive attitudes towards STEM subjects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=STEM%20Education" title="STEM Education">STEM Education</a>, <a href="https://publications.waset.org/abstracts/search?q=STEAM%20Education" title=" STEAM Education"> STEAM Education</a>, <a href="https://publications.waset.org/abstracts/search?q=Curriculum%20Instruction" title=" Curriculum Instruction"> Curriculum Instruction</a>, <a href="https://publications.waset.org/abstracts/search?q=Academically%20At-Risk%20Students" title=" Academically At-Risk Students"> Academically At-Risk Students</a>, <a href="https://publications.waset.org/abstracts/search?q=Singapore" title=" Singapore"> Singapore</a> </p> <a href="https://publications.waset.org/abstracts/62468/keynote-speech-guiding-teachers-to-make-lessons-relevant-appealing-and-personal-rap-for-academically-low-achieving-students-in-stem-subjects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62468.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">304</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> A Randomized Controlled Trial Study on the Effect of Adding Dexmedetomidine to Bupivacaine in Supraclavicular Block Using Ultrasound Guidance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nazia%20Nazir">Nazia Nazir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: The benefits of regional anesthetic techniques are well established. Use of additives to local anesthetics can prolong these benefits. The aim of this study was to observe the effect of adding dexmedetomidine to bupivacaine for the supraclavicular block. Methods (Design): In this randomized, double-blind study, seventy ASA I & II patients of either sex undergoing elective surgeries on the upper limb were given supraclavicular block under ultrasound guidance. Group C (n=35), received 38 mL 0.25% bupivacaine + 2mL normal saline and group D received 38 mL 0.25% bupivacaine + 1 µg/kg dexmedetomidine (2mL). Patients were observed for onset, duration of motor and sensory block, duration of analgesia, sedation score, hemodynamic changes and any adverse events. Results: In group D the onset was faster (P < 0.001), duration of sensory and motor block, as well as duration of analgesia, was prolonged as compared to group C (P < 0.0001). There was significant drop in heart rate (HR) from the baseline in group D (P < 0.05) at 30, 60, 90 and 120 min, however, none of the patients dropped HR below 50/min. Mean arterial Pressure (MAP) remained unaffected. The patients in group D were effectively sedated than those in group C (P < 0.05). No adverse event was reported in either group. Conclusion: Dexmedetomidine as adjuvant to bupivacaine in supraclavicular block resulted in faster action, prolonged motor and sensory block, prolonged analgesia with hemodynamic stability and adequate sedation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Analgesia" title="Analgesia">Analgesia</a>, <a href="https://publications.waset.org/abstracts/search?q=bupivacaine" title=" bupivacaine"> bupivacaine</a>, <a href="https://publications.waset.org/abstracts/search?q=dexmedetomidine" title=" dexmedetomidine"> dexmedetomidine</a>, <a href="https://publications.waset.org/abstracts/search?q=supraclavicular%20block" title=" supraclavicular block"> supraclavicular block</a> </p> <a href="https://publications.waset.org/abstracts/90335/a-randomized-controlled-trial-study-on-the-effect-of-adding-dexmedetomidine-to-bupivacaine-in-supraclavicular-block-using-ultrasound-guidance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90335.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">191</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> In-Vitro Stability of Aspergillus terreus Phytases in Relation to Different Physico-Chemical Factors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qaiser%20Akram">Qaiser Akram</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahsan%20Naeem"> Ahsan Naeem</a>, <a href="https://publications.waset.org/abstracts/search?q=Hafiz%20Muhammad%20Rizwan"> Hafiz Muhammad Rizwan</a>, <a href="https://publications.waset.org/abstracts/search?q=Waqas%20Ahmad"> Waqas Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Rubeena%20Yasmeen"> Rubeena Yasmeen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aspergillus has good secretory potential for phytases. Morphologically and microscopically identified Aspergillus terreus (A. terreus) (n=20) were screened for phytase production and non-toxicity. Phytases produced by non-toxigenic A. terreus under optimum conditions were quantified. Phytases of highest producer A. terreus were evaluated for stability after exposure to temperature (35, 55, 75 and 95ºC) and pH (2, 4, 6 and 8). Effect of metal ions (Fe⁺³, Ba⁺², Ca⁺², Cu⁺², Mg⁺², Mn⁺², K⁺¹ and Na⁺¹) was assessed on phytase activity. Log reduction in phytase activity was calculated. The highest activity units of phytase produced by A. terreus were 271.49 ± 8.14 phytase unit / mL (FTU/ mL). The lowest reduction in phytase activity was 50.20 ± 7.36 (18.5%) and 68.22 ± 10.3 FTU/mL (25.13%) at 35ºC and pH 6, respectively for 15 minutes. The highest reduction 259 ± 0.84 (95.5%) and 211.99 ± 4.39 FTU/mL (78.1%) was recorded at 95ºC for 60 minutes and pH 2.0 for 45 minutes exposure, respectively. All metal ions negatively affected phytase activity. Phytase activity was inhibited minimum (45.32 ± 28.54 FTU/mL, 16.69%) by K⁺¹(1 mM) and maximum (231.48 ± 3.68 FTU/mL, 80.8%) by Cu⁺² (10 mM). It was concluded that A. terreus phytase stability and activity was dependent on physio-chemical factors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stability" title="stability">stability</a>, <a href="https://publications.waset.org/abstracts/search?q=phytase" title=" phytase"> phytase</a>, <a href="https://publications.waset.org/abstracts/search?q=aspergillus%20terreus" title=" aspergillus terreus"> aspergillus terreus</a>, <a href="https://publications.waset.org/abstracts/search?q=physio-chemical%20factors%20and%20metal%20ions" title=" physio-chemical factors and metal ions"> physio-chemical factors and metal ions</a> </p> <a href="https://publications.waset.org/abstracts/159065/in-vitro-stability-of-aspergillus-terreus-phytases-in-relation-to-different-physico-chemical-factors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159065.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">46</span> Deposition of Diamond Like Carbon Thin Film by Pulse Laser Deposition for Surgical Instruments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Khalid%20Alamgir">M.

Pure graphite was used as a target. The vacuum in the deposition chamber was generated in the range of 10-6 mbar by turbo molecular pump. Ratio of sp3 to sp2 content shows amorphous nature of the film. This was confirmed by Raman spectra having two peaks around 1300 cm-1 i.e. D-band to 1700 cm-1 i.e. G-band. If sp3 bonding ratio is high, the films behave like diamond-like whereas, with high sp2, films are graphite-like. The ratio of sp3 and sp2 contents in the film depends upon the deposition method, hydrogen contents and system parameters. The structural study of the film was carried out by XRD. The hardness of the films as measured by Vickers hardness tester and was found to be 28 GPa. The EDX result shows the presence of carbon contents on the surface in high rate and optical microscopy result shows the smoothness of the film on substrate. The film possesses good adhesion and can be used to coat surgical instruments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DLC" title="DLC">DLC</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20film" title=" thin film"> thin film</a>, <a href="https://publications.waset.org/abstracts/search?q=Raman%20spectroscopy" title=" Raman spectroscopy"> Raman spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=XRD" title=" XRD"> XRD</a>, <a href="https://publications.waset.org/abstracts/search?q=EDX" title=" EDX"> EDX</a> </p> <a href="https://publications.waset.org/abstracts/29422/deposition-of-diamond-like-carbon-thin-film-by-pulse-laser-deposition-for-surgical-instruments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29422.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">564</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> Long Hours Impact on Work-Life Balance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syeda%20Faiza%20Gardazi">Syeda Faiza Gardazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Ahsan%20Ali%20Gardazi"> Syed Ahsan Ali Gardazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ajmal%20Waheed"> Ajmal Waheed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The trend of overtime is increasing among workers due to more pressure to perform workloads, job insecurity, and financial issues. Overtime work affects the work-life balance conflict negatively as well positively. Work-life balance conflict has become an important issue as traditional work and family roles have changed. The purpose of the current research was to study the impact of overtime work on work-life balance conflict along with the moderating role of job satisfaction. For this purpose, data is collected from the employees working in different public and private sectors of Pakistan using simple random sampling technique. Descriptive statistics was used for data presentation and analysis. Correlation and regression analysis were used to test four research hypotheses proposed on the basis of research framework. The findings led to the acceptance of four hypotheses. The results show that high working hours and overtime in general lead to high work-life balance conflict.

During any machining operation, high temperatures are generated at the tool-chip interface impairing surface quality and dimensional accuracy of products. Cutting fluids are generally applied during machining to reduce temperature at the tool-chip interface. However, usages of cutting fluids give rise to problems such as waste disposal, pollution, high cost, and human health hazard. Researchers, now-a-days, are opting towards dry machining and other cooling techniques to minimize use of coolants during machining while keeping surface roughness of products within desirable limits. In this paper, a concept of using peltier cooling effects during aluminium milling operation has been presented and adopted with an aim to improve surface roughness of the machined surface. Experimental evidence shows that peltier cooling effect provides better surface roughness of the machined surface compared to dry machining. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminium" title="aluminium">aluminium</a>, <a href="https://publications.waset.org/abstracts/search?q=milling%20operation" title=" milling operation"> milling operation</a>, <a href="https://publications.waset.org/abstracts/search?q=peltier%20cooling%20effect" title=" peltier cooling effect"> peltier cooling effect</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20roughness" title=" surface roughness"> surface roughness</a> </p> <a href="https://publications.waset.org/abstracts/67712/an-innovative-green-cooling-approach-using-peltier-chip-in-milling-operation-for-surface-roughness-improvement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67712.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">337</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> Monitoring of Humoral Immune Response of Monovalent and Combined PPR and FMD Serotype 'O' Virus Vaccines in Goats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mudassar%20Hameed">Mudassar Hameed</a>, <a href="https://publications.waset.org/abstracts/search?q=Khushi%20Muhammad"> Khushi Muhammad</a>, <a href="https://publications.waset.org/abstracts/search?q=Aamir%20Ghafoor"> Aamir Ghafoor</a>, <a href="https://publications.waset.org/abstracts/search?q=Masood%20%20Rabbani"> Masood Rabbani</a>, <a href="https://publications.waset.org/abstracts/search?q=Momena%20Habib"> Momena Habib</a>, <a href="https://publications.waset.org/abstracts/search?q=Jawad%20Nazir"> Jawad Nazir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Comparative efficacy of three formulations (non-adjuvant, gel, and oil adjuvant) of monovalent and combined PPR and FMD virus vaccines was evaluated in goats. All kinds of monovalent PPRV vaccines elicited protective antibody titers at one-month post vaccination (PV) that remained so till six months PV. Monovalent non-adjuvant (NA) FMDV vaccine provoked non-protective antibody titers that declined to undetectable levels after three months. In case of combined vaccines, all of the formulations elicited protective antibody titers against PPRV in vaccinated animals which remained above that limit for six months. However, an exceptional immune response against FMDV was observed in combined NA vaccine group where antibody titers were extremely high and remained above protective level till 4 months PV in animals who received a single vaccine shot and till six months PV in booster group. Although, adjuvant or NA combined vaccines can induce protective antibody titers against both of the viruses within one month PV, but a booster vaccine shot is needed to retain protective antibody level for 6 months duration. Immune response elicited by combined vaccines is comparable or superior to the monovalent vaccines. Hence combined vaccine can be effectively used for the control and prevention of both of the diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibody%20titer" title="antibody titer">antibody titer</a>, <a href="https://publications.waset.org/abstracts/search?q=protective" title=" protective"> protective</a>, <a href="https://publications.waset.org/abstracts/search?q=combined%20vaccine" title=" combined vaccine"> combined vaccine</a>, <a href="https://publications.waset.org/abstracts/search?q=non%20adjuvant" title=" non adjuvant"> non adjuvant</a> </p> <a href="https://publications.waset.org/abstracts/83674/monitoring-of-humoral-immune-response-of-monovalent-and-combined-ppr-and-fmd-serotype-o-virus-vaccines-in-goats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83674.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">204</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> Toxicities associated with EBRT and Brachytherapy for Intermediate and High Risk Prostate Cancer, Correlated with Intra-operative Dosing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rebecca%20Dunne">Rebecca Dunne</a>, <a href="https://publications.waset.org/abstracts/search?q=Cormac%20Small"> Cormac Small</a>, <a href="https://publications.waset.org/abstracts/search?q=Geraldine%20O%27Boyle"> Geraldine O'Boyle</a>, <a href="https://publications.waset.org/abstracts/search?q=Nazir%20Ibrahim"> Nazir Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Anisha"> Anisha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Prostate cancer is the most common cancer among men, excluding non-melanoma skin cancers. It is estimated that approximately 12% of men will develop prostate cancer during their lifetime. Patients with intermediate, high risk, and very-high risk prostate cancer often undergo a combination of radiation treatments. These treatments include external beam radiotherapy with a low-dose rate or high-dose rate brachytherapy boost, often with concomitant androgen deprivation therapy. The literature on follow-up of patients that receive brachytherapy is scarce, particularly follow-up of patients that undergo high-dose rate brachytherapy. This retrospective study aims to investigate the biochemical failure and toxicities associated with triple therapy and external beam radiotherapy given in combination with brachytherapy. Reported toxicities and prostate specific antigen (PSA) were retrospectively evaluated in eighty patients that previously underwent external beam radiotherapy with a low-dose rate or high dose-rate brachytherapy boost. The severity of toxicities were correlated with intra-operative dosing during brachytherapy on ultrasound and CT scan. The results of this study will provide further information for clinicians and patients when considering treatment options. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=toxicities" title="toxicities">toxicities</a>, <a href="https://publications.waset.org/abstracts/search?q=combination" title=" combination"> combination</a>, <a href="https://publications.waset.org/abstracts/search?q=brachytherapy" title=" brachytherapy"> brachytherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=intra-operative%20dosing" title=" intra-operative dosing"> intra-operative dosing</a>, <a href="https://publications.waset.org/abstracts/search?q=biochemical%20failure" title=" biochemical failure"> biochemical failure</a> </p> <a href="https://publications.waset.org/abstracts/140057/toxicities-associated-with-ebrt-and-brachytherapy-for-intermediate-and-high-risk-prostate-cancer-correlated-with-intra-operative-dosing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140057.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">243</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">41</span> Personnel Training of Automotive Manufacturers in Virtual Reality</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mirza%20Ahsan%20Baig">Mirza Ahsan Baig</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Evans"> Paul Evans</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the high demand for automobiles, manufacturers have to run their production lines non-stop for long periods. At such a scale, unplanned downtime could cost up to $50 billion annually. Improper training of new hires could lead to safety issues causing unplanned downtimes. The project developed a virtual reality simulation that could train personnel for key operations on an automobile manufacturing floor, reducing the risk of unplanned downtime while eliminating any disruption (due to training) on the assembly line. An automation firm sponsored it to explore the possibilities the likes of Jaguar and BMW are yet to achieve! The project was inspired by Bentley, the only company that succeeded in simulation training scenarios within virtual space. The project aims to inspire other significant firms to do the same. It was increasing employee safety, eliminating downtimes, and improving efficiency. The developed prototype uncovered various limitations within existing simulation providers and was able to simulate state-of-the-art training scenarios. It also explored the possibility of a multiuser interface and resolved complex issues such as lack of movement space within the training area. <p class="card-text"><strong>Keywords:</strong> <a
