crucial need for advocating early prophylactic majors to control protozoal infection. 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">30</span> The Characterisation of TLC NAND Flash Memory, Leading to a Definable Endurance/Retention Trade-Off</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sorcha%20Bennett">Sorcha Bennett</a>, <a href="https://publications.waset.org/abstracts/search?q=Joe%20Sullivan"> Joe Sullivan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Triple-Level Cell (TLC) NAND Flash memory at, and below, 20nm (nanometer) is still largely unexplored by researchers, and with the ever more commonplace existence of Flash in consumer and enterprise applications there is a need for such gaps in knowledge to be filled.

In face of massive, parallel and varied data on board, efficient data management become an important issue of storage research. Face to the requirements of high-performance and reliability in Nand Flash storage system, a combination of hardware and file system design can drastically increase system dependability, even for missions with a very long duration. More sophisticated flash storage concepts with advanced operating systems have been researched to improve the reliability of Nand Flash storage system on satellites. In this paper, architecture of file system with multi-channel data acquisition and storage on board is proposed, which obtains large-capacity and high-performance with the combine of intra-channel pipeline and device partition in Nand Flash. Multi-channel data in different rate are stored as independent files with parallel-storage system in device partition, which assures the high-effective and reliable throughput of file treatments. For massive and high-speed data storage, an efficiency assessment model is established to calculate the bandwidth formula of intra-channel pipeline. Information tables designed in Magnetoresistive RAM (MRAM) hold the management of bad block in Nand Flash and the arrangement of file system address for the high-reliability of data storage. During the full-load test, the throughput of 3D PLUS Module 160Gb Nand Flash can reach 120Mbps for store and reach 120Mbps for playback, which efficiently satisfies the requirement of multi-channel data acquisition in Satellite. Compared with previous literature, the results of experiments verify the advantages of the proposed system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=device%20partition%20architecture" title="device partition architecture">device partition architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=intra-channel%20pipelining" title=" intra-channel pipelining"> intra-channel pipelining</a>, <a href="https://publications.waset.org/abstracts/search?q=nand%20flash" title=" nand flash"> nand flash</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel%20storage" title=" parallel storage"> parallel storage</a> </p> <a href="https://publications.waset.org/abstracts/68045/a-high-reliable-space-borne-file-system-with-applications-of-device-partition-and-intra-channel-pipeline-in-nand-flash" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68045.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">289</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Design and Performance Improvement of Three-Dimensional Optical Code Division Multiple Access Networks with NAND Detection Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Satyasen%20Panda">Satyasen Panda</a>, <a href="https://publications.waset.org/abstracts/search?q=Urmila%20Bhanja"> Urmila Bhanja</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we have presented and analyzed three-dimensional (3-D) matrices of wavelength/time/space code for optical code division multiple access (OCDMA) networks with NAND subtraction detection technique. The 3-D codes are constructed by integrating a two-dimensional modified quadratic congruence (MQC) code with one-dimensional modified prime (MP) code. The respective encoders and decoders were designed using fiber Bragg gratings and optical delay lines to minimize the bit error rate (BER). The performance analysis of the 3D-OCDMA system is based on measurement of signal to noise ratio (SNR), BER and eye diagram for a different number of simultaneous users. Also, in the analysis, various types of noises and multiple access interference (MAI) effects were considered. The results obtained with NAND detection technique were compared with those obtained with OR and AND subtraction techniques. The comparison results proved that the NAND detection technique with 3-D MQC\MP code can accommodate more number of simultaneous users for longer distances of fiber with minimum BER as compared to OR and AND subtraction techniques. The received optical power is also measured at various levels of BER to analyze the effect of attenuation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cross%20Correlation%20%28CC%29" title="Cross Correlation (CC)">Cross Correlation (CC)</a>, <a href="https://publications.waset.org/abstracts/search?q=Three%20dimensional%20Optical%20Code%20Division%20Multiple%20Access%20%283-D%20OCDMA%29" title=" Three dimensional Optical Code Division Multiple Access (3-D OCDMA)"> Three dimensional Optical Code Division Multiple Access (3-D OCDMA)</a>, <a href="https://publications.waset.org/abstracts/search?q=Spectral%20Amplitude%20Coding%20Optical%20Code%20Division%20Multiple%20Access%20%28SAC-OCDMA%29" title=" Spectral Amplitude Coding Optical Code Division Multiple Access (SAC-OCDMA)"> Spectral Amplitude Coding Optical Code Division Multiple Access (SAC-OCDMA)</a>, <a href="https://publications.waset.org/abstracts/search?q=Multiple%20Access%20Interference%20%28MAI%29" title=" Multiple Access Interference (MAI)"> Multiple Access Interference (MAI)</a>, <a href="https://publications.waset.org/abstracts/search?q=Phase%20Induced%20Intensity%20Noise%20%28PIIN%29" title=" Phase Induced Intensity Noise (PIIN)"> Phase Induced Intensity Noise (PIIN)</a>, <a href="https://publications.waset.org/abstracts/search?q=Three%20Dimensional%20Modified%20Quadratic%20Congruence%2FModified%20Prime%20%283-D%20MQC%2FMP%29%20code" title=" Three Dimensional Modified Quadratic Congruence/Modified Prime (3-D MQC/MP) code"> Three Dimensional Modified Quadratic Congruence/Modified Prime (3-D MQC/MP) code</a> </p> <a href="https://publications.waset.org/abstracts/57485/design-and-performance-improvement-of-three-dimensional-optical-code-division-multiple-access-networks-with-nand-detection-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57485.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">412</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Low Power Glitch Free Dual Output Coarse Digitally Controlled Delay Lines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Shaji%20Mon">K.

This claim is nowadays pushing toward a new circuit design paradigm in which the traditional analog signal processing is expected to be progressively substituted by the processing of times in the digital domain. Within this novel paradigm, digitally controlled delay lines (DCDL) should play the role of digital-to-analog converters in traditional, analog-intensive, circuits. Digital delay locked loops are highly prevalent in integrated systems.The proposed paper addresses the glitches present in delay circuits along with area,power dissipation and signal integrity.The digitally controlled delay lines(DCDL) under study have been designed in a 90 nm CMOS technology 6 layer metal Copper Strained SiGe Low K Dielectric. Simulation and synthesis results show that the novel circuits exhibit no glitches for dual output coarse DCDL with less power dissipation and consumes less area compared to the glitch free NAND based DCDL. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glitch%20free" title="glitch free">glitch free</a>, <a href="https://publications.waset.org/abstracts/search?q=NAND-based%20DCDL" title=" NAND-based DCDL"> NAND-based DCDL</a>, <a href="https://publications.waset.org/abstracts/search?q=CMOS" title=" CMOS"> CMOS</a>, <a href="https://publications.waset.org/abstracts/search?q=deep-submicrometer" title=" deep-submicrometer"> deep-submicrometer</a> </p> <a href="https://publications.waset.org/abstracts/2876/low-power-glitch-free-dual-output-coarse-digitally-controlled-delay-lines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2876.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">245</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Developing NAND Flash-Memory SSD-Based File System Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaechun%20No">Jaechun No</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper focuses on I/O optimizations of N-hybrid (New-Form of hybrid), which provides a hybrid file system space constructed on SSD and HDD.

The defect of metal break located on the step is one of the main failure mechanisms of bipolar ICs, resulting in open-circuit or functional failure. In this situation, general failure localization methods like optical beam-induced resistance change (OBIRCH) and photon emission microscopy (PEM) might not be fully effective. However, active voltage contrast (AVC) can be used as a voltage probe, which may pinpoint the incorrect potential and thus locate the failure position. Two case studies will be present in this paper on how to implement AVC for failure localization, and the detailed failure mechanism will be discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bipolar%20IC" title="bipolar IC">bipolar IC</a>, <a href="https://publications.waset.org/abstracts/search?q=failure%20localization" title=" failure localization"> failure localization</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20break" title=" metal break"> metal break</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20failure" title=" open failure"> open failure</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20contrast" title=" voltage contrast"> voltage contrast</a> </p> <a href="https://publications.waset.org/abstracts/132527/failure-localization-of-bipolar-integrated-circuits-by-implementing-active-voltage-contrast" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132527.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">291</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Deconstructing the Dialectics of Gender: An Analysis of Nigerian Igbo Women's Writing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Vidhya">R. Vidhya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nigeria, the seat of canonical literature in Africa, though widely acclaimed as the literary capital of the continent, it failed to produce women writers in its literary arena till the 1960s. Only after 1966, with the publication of the first novel by a women writer, Nigeria saw the emergence of women’s writing through which the world witnessed an upsurge in the sensitization of women’s issues in Africa. The Nigerian Igbo women’s writing threw light on gender discrimination in postcolonial Africa. Their works were instrumental in bringing a remarkable change in the perception of gender in a male dominated society. The social mindscape of the land which strongly believed that feminist ideologies could be highly detrimental to its patriarchal setup is slowly changed through the changing perspectives of gender. This paper aims to analyse the select works of Flora Nwapa, Buchi Emecheta and Chimamanda Ngozi Adichie to deconstruct the dialectics of gender, which has been realised in the works of these women writers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender%20discrimination" title="gender discrimination">gender discrimination</a>, <a href="https://publications.waset.org/abstracts/search?q=Igbo%20women%27s%20writings" title=" Igbo women's writings"> Igbo women's writings</a>, <a href="https://publications.waset.org/abstracts/search?q=postcolonial%20Africa" title=" postcolonial Africa"> postcolonial Africa</a>, <a href="https://publications.waset.org/abstracts/search?q=changing%20perspective" title=" changing perspective"> changing perspective</a> </p> <a href="https://publications.waset.org/abstracts/58761/deconstructing-the-dialectics-of-gender-an-analysis-of-nigerian-igbo-womens-writing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58761.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">384</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> PIN-Diode Based Slotted Reconfigurable Multiband Antenna Array for Vehicular Communication </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gaurav%20Upadhyay">Gaurav Upadhyay</a>, <a href="https://publications.waset.org/abstracts/search?q=Nand%20Kishore"> Nand Kishore</a>, <a href="https://publications.waset.org/abstracts/search?q=Prashant%20Ranjan"> Prashant Ranjan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shivesh%20Tripathi"> Shivesh Tripathi</a>, <a href="https://publications.waset.org/abstracts/search?q=V.%20S.%20Tripathi"> V.

The antenna consists of 2-element patch array. The antenna array is operating at multiple frequency bands. The multiband operation is achieved by use of slots at proper locations at the patch. The array is made reconfigurable by use of two PIN-diodes. The antenna is simulated and measured in four states of diodes i.e. ON-ON, ON-OFF, OFF-ON, and OFF-OFF. In ON-ON state of diodes, the resonant frequencies are 4.62-4.96, 6.50-6.75, 6.90-7.01, 7.34-8.22, 8.89-9.09 GHz. In ON-OFF state of diodes, the measured resonant frequencies are 4.63-4.93, 6.50-6.70 and 7.81-7.91 GHz. In OFF-ON states of diodes the resonant frequencies are 1.24-1.46, 3.40-3.75, 5.07-5.25 and 6.90-7.20 GHz and in the OFF-OFF state of diodes 4.49-4.75 and 5.61-5.98 GHz. The maximum bandwidth of the proposed antenna is 16.29%. The peak gain of the antenna is 3.4 dB at 5.9 GHz, which makes it suitable for vehicular communication. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antenna" title="antenna">antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=array" title=" array"> array</a>, <a href="https://publications.waset.org/abstracts/search?q=reconfigurable" title=" reconfigurable"> reconfigurable</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicular" title=" vehicular"> vehicular</a> </p> <a href="https://publications.waset.org/abstracts/85090/pin-diode-based-slotted-reconfigurable-multiband-antenna-array-for-vehicular-communication" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85090.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">256</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">21</span> Cooperative Coevolution for Neuro-Evolution of Feed Forward Networks for Time Series Prediction Using Hidden Neuron Connections</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ravneil%20Nand">Ravneil Nand</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cooperative coevolution uses problem decomposition methods to solve a larger problem.

SSD parallelization is affected by allocation scheme and it is directly connected to SSD performance. There are dynamic allocation and static allocation in representative allocation schemes. Dynamic allocation is more adaptive in exploiting write operation parallelism, while static allocation is better in read operation parallelism. Therefore, it is hard to select the appropriate allocation scheme when the workload is mixed read and write operations. We simulated conditions on a few mixed data patterns and analyzed the results to help the right choice for better performance.

These SSD potentials have drawn great attention from IT enterprises that seek for better I/O performance. However, high SSD cost per capacity makes it less desirable to construct a large-scale storage subsystem solely composed of SSD devices. An alternative is to build a hybrid storage subsystem where both HDD and SSD devices are incorporated in an economic manner, while employing the strengths of both devices. This paper presents a hybrid file system, called hybridFS, that attempts to utilize the advantages of HDD and SSD devices, to provide a single, virtual address space by integrating both devices. HybridFS not only proposes an efficient implementation for the file management in the hybrid storage subsystem but also suggests an experimental framework for making use of the excellent features of existing file systems. Several performance evaluations were conducted to verify the effectiveness and suitability of hybridFS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hybrid%20file%20mapping" title="hybrid file mapping">hybrid file mapping</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20layout" title=" data layout"> data layout</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20device%20integration" title=" hybrid device integration"> hybrid device integration</a>, <a href="https://publications.waset.org/abstracts/search?q=extent%20allocation" title=" extent allocation"> extent allocation</a> </p> <a href="https://publications.waset.org/abstracts/16492/utilizing-hybrid-file-mapping-for-high-performance-io" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16492.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">17</span> Assessment of Land Surface Temperature Using Satellite Remote Sensing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Vidhya">R.

Considered to be a cumulative effect of all these impacts is the Urban Heat Island. In this paper, the urban heat island effect is studied for the Chennai city, TamilNadu, South India using satellite remote sensing data. LANDSAT 8 OLI and TIRS DATA acquired on 9th September 2014 were used to Land Surface Temperature (LST) map, vegetation fraction map, Impervious surface fraction, Normalized Difference Water Index (NDWI), Normalized Difference Building Index (NDBI) and Normalized Difference Vegetation Index (NDVI) map. The relationship among LST, Vegetation fraction, NDBI, NDWI, and NDVI was calculated. The Chennai city’s Urban Heat Island effect is significant, and the results indicate LST has strong negative correlation with the vegetation present and positive correlation with NDBI. The vegetation is the main factor to control urban heat island effect issues in urban area like Chennai City. This study will help in developing measures to land use planning to reduce the heat effects in urban area based on remote sensing derivatives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=land%20surface%20temperature" title="land surface temperature">land surface temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=brightness%20temperature" title=" brightness temperature"> brightness temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=emissivity" title=" emissivity"> emissivity</a>, <a href="https://publications.waset.org/abstracts/search?q=vegetation%20index" title=" vegetation index"> vegetation index</a> </p> <a href="https://publications.waset.org/abstracts/82927/assessment-of-land-surface-temperature-using-satellite-remote-sensing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82927.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">274</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">16</span> Real Estate Rigidities: The Effect of Cash Transactions and the Impact of Demonetisation on Them</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dishant%20Shahi">Dishant Shahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Aradhya%20Shandilya"> Aradhya Shandilya</a>, <a href="https://publications.waset.org/abstracts/search?q=Nand%20Kumar"> Nand Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We study here the impact of the black component referred to as X component in the text on Real estate transactions. The X component involved not only acts as friction in transaction but also leads to dysfunctionality in the capital market of real estate. The effect of the component is presented by using a model of economy which seeks resemblance with that of India involving property deals. The rigidities which hinder smooth transactions in property or land deals are depicted and their impact on the economy as a whole has been modelled. The effect of subprime crisis (2007) on Indian housing capital market and the role which the X component played during it, is also included in one of the sections. In the entire text, we have utilised 4 Quadrant graphs to study supply and demand causalities involved in commercial real estate. At the end we have included the impact of demonetisation as a move to counter the problem of overvaluation in the property assets arising due to the X component.

A major part of this waste comprises printed circuit boards (PCBs). Edge trims of PCBs have high copper content ranging between 25-60%. The extraction of various metals out of these PCBs is more or less a proven technology, wherein various hazardous chemicals are being used in the resource recovery, resulting into secondary pollution. The current trend of extracting of valuable metals is the utilization of microbial strains to eliminate the problem of a secondary pollutant. Keeping the above context in mind, this work aims at the enhanced recovery of copper from edge trims, through bioleaching using bacterial strain Acidithiobacillus ferrooxidans. The raw material such as motherboards, hard drives, floppy drives and DVD drives were obtained from the warehouse of the University. More than 90% copper could be extracted through bioleaching using Acidithiobacillus ferrooxidans. Inoculate concentration has merely insignificant effect over copper recovery above 20% inoculate concentration. Higher concentration of inoculation has the only initial advantage up to 2-4 days.

It is a wet-chemical technique which is used primarily for fabrication of silicate gel which is usually allowed to dry as per requirement. The outcome is solid rock hard material which is porous and has lots of applications in different fields. Taking porosity as a key factor, allethrin a naturally occurring synthetic compound with molecular mass 302.40 was entrapped inside the sol-gel matrix as a dopant. Allethrin is commonly used as an insecticide and is a key ingredient in commercially available mosquitoes repellent in Asian and subtropical countries. It has low toxicity for humans and birds, and are used in many household insecticides such as RAID as well as mosquito coils. They are however highly toxic to fish and bees. Insects subject to its exposure become paralyzed (nervous system effect) before dying. They are also used as an ultra-low volume spray for outdoor mosquito control. Therefore, there is a need for controlled release of allethrin in the environment. For controlled release of allethrin from sol-gel matrix, its (allethrin) we utilized temperature based controlled evaporation through porous sol-gel. Different types of fabric like cotton, Terri-cotton, polyester, surgical cap, knee-cap etc are studied and the best with maximum absorption capacity is selected to hold the sol-gel matrix with maximum quantity.

Recent researches reveal that the teacher learning communities enhance the quality of teacher. It is a proven fact that community does help in enhancing teachers’ self-esteem as professionals, their teaching skills and enhancing classroom transaction that results in the higher achievement of students. The purpose of this study is to develop TLC and provide them platform where they share their views and ideas on various academic issues. The study examines how teachers conceptualize TLCs, up to what extent TLC help in developing professionalism among teachers and how they prepare themselves for the days to come. In this study, pre-test in five subjects, Hindi, English, Mathematics, Science and Social Studies was conducted and a questionnaire was designed to judge the teachers' attitude towards teaching practice. After completion of the project duration of three and a half-month, an exercise of post-test was conducted in all the above subjects. The post tests show tremendous improvements in achievement level of those students who were regular in their classes and were attended through this new method. A visible shift in teacher’s attitude is seen for the better. They were able to realize their own potentials. There was a group of Facilitators formed to perform continuously supervision and monitor in regular intervals so that they could easily handle the challenges, and factors much important for the attainment towards the fulfillment of the objectives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=teacher%20learning%20communities" title="teacher learning communities">teacher learning communities</a>, <a href="https://publications.waset.org/abstracts/search?q=best%20practice" title=" best practice"> best practice</a>, <a href="https://publications.waset.org/abstracts/search?q=teacher%20professionalism" title=" teacher professionalism"> teacher professionalism</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20achievement" title=" student achievement"> student achievement</a> </p> <a href="https://publications.waset.org/abstracts/52410/transforming-professional-learning-communities-and-centers-a-case-study-of-luck-now-district-uttar-pradesh-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52410.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">218</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">12</span> From Being to Becoming: Emancipation and Empowerment in the African Diaspora</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Vidhya">R.

Isolation and the strong feelings of insecurity and inferiority due to constant marginalization coupled with a nostalgia for their motherland, its customs, culture, language, food and people which keep haunting the minds of immigrants are the major themes that are handled by diasporic writers. In the African diaspora, more than the men, it is the women who face the brunt and burden of the triple jeopardy – the racial, class and gender discrimination. Women writers from Africa have successfully sketched the plight of African women in the diaspora. Buchi Emecheta, a Nigerian woman writer deftly portrays the African Diaspora in her novels. She skillfully weaves her stories with her own experiences as an immigrant in the United Kingdom. She portrays the immigrant life and psychology through numerous themes like exile, geographical shift of locations, transactions of culture, political instability and the dilemma of moral and religious ideologies in her diasporic novels Second-class Citizen, Gwendolyn and Kehinde. The contemporary Nigerian woman writer Chimamanda Ngozi Adichie has also dexterously depicted the diasporic dilemma of her protagonist Ifemelu in Americannah, who initially has the experience of a despondent and a downcast in the United States of America. This paper aims to analyse the diasporic sentiments and sensibilities of the Nigerian Igbo women writers Buchi Emecheta and Chimamanda Ngozi Adichie whose women characters finally find emancipation and empowerment in the African Diaspora. This study is based on the Africana Womanist Literary theory propounded by Clenora Hudson-Weems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=African%20Diaspora" title="African Diaspora">African Diaspora</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigerian%20women%20writers" title=" Nigerian women writers"> Nigerian women writers</a>, <a href="https://publications.waset.org/abstracts/search?q=Buchi%20Emecheta" title=" Buchi Emecheta"> Buchi Emecheta</a>, <a href="https://publications.waset.org/abstracts/search?q=Chimamanda%20Ngozi%20Adichie" title=" Chimamanda Ngozi Adichie"> Chimamanda Ngozi Adichie</a>, <a href="https://publications.waset.org/abstracts/search?q=emancipation" title=" emancipation"> emancipation</a>, <a href="https://publications.waset.org/abstracts/search?q=empowerment" title=" empowerment"> empowerment</a> </p> <a href="https://publications.waset.org/abstracts/57701/from-being-to-becoming-emancipation-and-empowerment-in-the-african-diaspora" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57701.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">11</span> Mapping the Metamorphosis of the Nigerian Female: A Womanist Approach to the Novels of Chimamanda Ngozi Adichie</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vidhya%20R">Vidhya R</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The claim of feminists that women are made and not born is neither to set women on par with men nor to discriminate one from the other, but to establish and reiterate the fact that both the sexes have to understand, recognize and appreciate each other’s ability and responsibility thus to contribute to the peaceful co-existence of both, leading to the creation of a better and brave new world, which is neither patriarchal nor matriarchal. But history has repeatedly recorded the relegation of women to the secondary position consummated through the highly biased cultural, ritualistic and customary practices across the globe. In Africa, bracing herself against many odds through generations, the African woman who has been facing multiple jeopardy promulgated by racial, cultural, economic and gender discrimination has slowly started moving from the margins towards the center. The African woman was able to undertake the journey from the margins to the center bravely only because of her grit, grace, courage, confidence, and spirituality. This journey has resulted in the metamorphosis of the African woman’s psyche. Economic independence fortified with education has empowered the African woman. The various stages of metamorphosis are well delineated in the works of the contemporary Nigerian writer Chimamanda Ngozi Adichie. The objective of this research paper is to study the above said metamorphosis, the female protagonists undergo in Adichie’s novels. The approaches on which the study is based on are the Africana Womanist theory propounded by Clenora Hudson –Weems and African feminism of Carole Boyce Davies. The findings of this study lead towards establishing the proposition that the emergence and evolution of the Nigerian woman has resulted in the birth of a new breed of women – the Emphatic Female, manifested in the power packed portrayal of the female protagonists of Purple Hibiscus, Half of a Yellow Sun and Americanah by Chimamanda Ngozi Adichie. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Africana%20womanism" title="Africana womanism">Africana womanism</a>, <a href="https://publications.waset.org/abstracts/search?q=African%20feminism" title=" African feminism"> African feminism</a>, <a href="https://publications.waset.org/abstracts/search?q=chimamanda%20ngozi%20adichie" title=" chimamanda ngozi adichie"> chimamanda ngozi adichie</a>, <a href="https://publications.waset.org/abstracts/search?q=metamorphosis" title=" metamorphosis"> metamorphosis</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20emphatic%20female" title=" the emphatic female"> the emphatic female</a> </p> <a href="https://publications.waset.org/abstracts/55548/mapping-the-metamorphosis-of-the-nigerian-female-a-womanist-approach-to-the-novels-of-chimamanda-ngozi-adichie" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55548.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">352</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">10</span> Cognitive Rehabilitation in Schizophrenia: A Review of the Indian Scenario</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Garima%20Joshi">Garima Joshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Pratap%20Sharan"> Pratap Sharan</a>, <a href="https://publications.waset.org/abstracts/search?q=V.%20Sreenivas"> V.

Often the cognitive symptoms are in their prodromal state and worsen as the illness progresses; they have proven to have a good predictive value for the prognosis of the illness. It has been shown that intensive cognitive rehabilitation (CR) leads to improvements in the healthy as well as cognitively-impaired subjects. As the majority of population in India falls in the lower to middle socio-economic status and have low education levels, using the existing packages, a majority of which are developed in the West, for cognitive rehabilitation becomes difficult. The use of technology is also restricted due to the high costs involved and the limited availability and familiarity with computers and other devices, which pose as an impedance for continued therapy. Cognitive rehabilitation in India uses a plethora of retraining methods for the patients with schizophrenia targeting the functions of attention, information processing, executive functions, learning and memory, and comprehension along with Social Cognition. Psychologists often have to follow an integrative therapy approach involving social skills training, family therapy and psychoeducation in order to maintain the gains from the cognitive rehabilitation in the long run. This paper reviews the methodologies and cognitive retaining programs used in India. It attempts to elucidate the evolution and development of methodologies used, from traditional paper-pencil based retraining to more sophisticated neuroscience-informed techniques in cognitive rehabilitation of deficits in schizophrenia as home-based or supervised and guided programs for cognitive rehabilitation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=schizophrenia" title="schizophrenia">schizophrenia</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20rehabilitation" title=" cognitive rehabilitation"> cognitive rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=neuropsychological%20interventions" title=" neuropsychological interventions"> neuropsychological interventions</a>, <a href="https://publications.waset.org/abstracts/search?q=integrated%20approached%20to%20rehabilitation" title=" integrated approached to rehabilitation"> integrated approached to rehabilitation</a> </p> <a href="https://publications.waset.org/abstracts/58757/cognitive-rehabilitation-in-schizophrenia-a-review-of-the-indian-scenario" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58757.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">363</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">9</span> Caregiver’s Perception Regarding Diagnosis Disclosure to Children Living with Human Immunodeficiency Virus in Resource-Limited Settings: Observational Study from India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ramesh%20Chand%20Chauhan">Ramesh Chand Chauhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjay%20Kumar%20Rai"> Sanjay Kumar Rai</a>, <a href="https://publications.waset.org/abstracts/search?q=Shashi%20kant"> Shashi kant</a>, <a href="https://publications.waset.org/abstracts/search?q=Rakesh%20Lodha"> Rakesh Lodha</a>, <a href="https://publications.waset.org/abstracts/search?q=Nand%20Kumar"> Nand Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: With a better understanding of HIV pathogenesis and availability of antiretroviral therapy more children are growing and entering in teenage group; informing children of their own HIV status has become an important aspect of long-term disease management. There is little evidence of how and when this type of disclosure takes place in a resource-limited setting. Methods: A cross-sectional study was conducted from June 2010 to May 2011 among a dyads of 156 HIV-infected children and their caregivers, those were visiting pediatric clinic at a tertiary care hospital in Delhi, India. The study protocol was approved by the Institute Ethics Committee. After taking written informed consent; pretested structured questionnaire was administered to caregivers during routine clinic visits. Information regarding socio-demographic characteristics, awareness of HIV infection status among children and their perception regarding disclosure was collected. Mean and frequencies were calculated and chi-square and logistic regression test were applied. Results: The mean age of children was 8.4 ±3.45 years. Among them 73.7% were male and 39.1% were orphans. Among 156 enrolled children, 74.4% (n=116) were of ≥ 6 years and were assessed for disclosure. Only 18.1% (n=21) children had been informed of their HIV status. Of those under 9 years, 6.4% knew their status, whereas 18.4% of 9-11 years and 35.5% of 12-14 years children knew they had HIV. Awareness among males (23.3%) was higher than females (3.3%). Both age and sex of child were significantly (p<0.01) associated with disclosure status. Other factors favoring disclosure were orphan-hood, non-perinatal mode of transmission (OR = 4.32; 95% CI 1.01-7.12), ART initiation (OR = 4.21; 95% CI 1.03-6.98), and caregiver educated beyond primary level (OR = 1.89; 95% CI 1.03-3.26). Repeated enquiry regarding the visit to clinic was the most common reason (66.6%) for disclosure. In 52.4% children disclosure was done with the involvement of other family members. 82.5% caregivers felt the age of > 10 years is appropriate for disclosing the HIV infection status to the child. Conclusion: Detailed guidelines on disclosure are required focusing on children of school-going age with perinatal infection who are not on ART and with caregivers of low educational status. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HIV" title="HIV">HIV</a>, <a href="https://publications.waset.org/abstracts/search?q=children" title=" children"> children</a>, <a href="https://publications.waset.org/abstracts/search?q=India" title=" India"> India</a>, <a href="https://publications.waset.org/abstracts/search?q=disclosure" title=" disclosure"> disclosure</a> </p> <a href="https://publications.waset.org/abstracts/14629/caregivers-perception-regarding-diagnosis-disclosure-to-children-living-with-human-immunodeficiency-virus-in-resource-limited-settings-observational-study-from-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14629.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">635</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">8</span> Antimicrobial Action and Its Underlying Mechanism by Methanolic Seed Extract of Syzygium cumini on Bacillus subtilis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alok%20Kumar%20Yadav">Alok Kumar Yadav</a>, <a href="https://publications.waset.org/abstracts/search?q=Saurabh%20Saraswat"> Saurabh Saraswat</a>, <a href="https://publications.waset.org/abstracts/search?q=Preeti%20Sirohi"> Preeti Sirohi</a>, <a href="https://publications.waset.org/abstracts/search?q=Manjoo%20Rani"> Manjoo Rani</a>, <a href="https://publications.waset.org/abstracts/search?q=Sameer%20Srivastava"> Sameer Srivastava</a>, <a href="https://publications.waset.org/abstracts/search?q=Manish%20Pratap%20Singh"> Manish Pratap Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Nand%20K.%20Singh"> Nand K.

In many countries, people use the medicinal plants for the treatment of various diseases as these are cheaper, easily available and least toxic. Syzygium cumini is used for the treatment of various kinds of diseases but their mechanism of action is not reported. The antimicrobial activity of Syzygium cumini was tested by the well diffusion assay and zone of inhibition was reported to be 20.06 mm as compared to control with MIC of 0.3 mg/ml. Genomic DNA fragmentation of Bacillus subtilis revealed apoptosis and FE-SEM indicate cell wall cracking on several intervals of time. Propidium iodide staining results showed that few bacterial cells were stained in the control and population of stained cells increase after exposing them for various period of time. Flow cytometric kinetic data analysis on the membrane permeabilization in bacterial cell showed the significant contribution of antimicrobial potential of the seed extract on antimicrobial-induced permeabilization. Two components of Syzygium cumini methanolic seed extract was found to be quite active against four enzymes like PDB ID- 1W5D, 4OX3, 3MFD and 5E2F which have a very crucial role in membrane synthesis in Bacillus subtilis by in silico analysis. Through in silico analysis, lupeol showed highest binding energy for macromolecule 1W5D and 4OX3 whereas stigmasterol showed the highest binding energy for macromolecule 3MFD and 5E2F respectively. It showed that methanolic seed extract of Syzygium cumini can be used for the inhibition of foodborne infections caused by Bacillus subtilis and also as an alternative of prevalent antibiotics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibiotics" title="antibiotics">antibiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=Bacillus%20subtilis" title=" Bacillus subtilis"> Bacillus subtilis</a>, <a href="https://publications.waset.org/abstracts/search?q=inhibition" title=" inhibition"> inhibition</a>, <a href="https://publications.waset.org/abstracts/search?q=Syzygium%20cumini" title=" Syzygium cumini"> Syzygium cumini</a> </p> <a href="https://publications.waset.org/abstracts/85752/antimicrobial-action-and-its-underlying-mechanism-by-methanolic-seed-extract-of-syzygium-cumini-on-bacillus-subtilis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85752.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">199</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">7</span> Occupational Heat Stress Related Adverse Pregnancy Outcome: A Pilot Study in South India Workplaces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rekha%20S.">Rekha S.</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20J.%20Nalini"> S.

The presence of heat in the workplace is expected to lead to Adverse Pregnancy Outcomes (APO), especially in tropical countries where temperatures are rising and workplace cooling interventions are minimal. For effective interventions, in-depth understanding and evidence about occupational heat stress and APO are required. Methodology: Approximately 800 pregnant women in and around Chennai who were employed in jobs requiring moderate to hard labour participated in the cohort research. During the study period (2014-2019), environmental heat exposures were measured using a Questemp WBGT monitor, and heat strain markers, such as Core Body Temperature (CBT) and Urine Specific Gravity (USG), were evaluated using an Infrared Thermometer and a refractometer, respectively. Using a valid HOTHAPS questionnaire, self-reported health symptoms were collected. In addition, a postpartum follow-up with the mothers was done to collect APO-related data. Major findings of the study: Approximately 47.3% of pregnant workers have workplace WBGTs over the safe manual work threshold value for moderate/heavy employment (Average WBGT of 26.6°C±1.0°C). About 12.5% of the workers had CBT levels above the usual range, and 24.8% had USG levels above 1.020, both of which suggested mild dehydration. Miscarriages (3%), stillbirths/preterm births (3.5%), and low birth weights (8.8%) were the most common unfavorable outcomes among pregnant employees. In addition, WBGT exposures above TLVs during all trimesters were associated with a 2.3-fold increased risk of adverse fetal/maternal outcomes (95% CI: 1.4-3.8), after adjusting for potential confounding variables including age, education, socioeconomic status, abortion history, stillbirth, preterm, LBW, and BMI. The study determined that WBGTs in the workplace had direct short- and long-term effects on the health of both the mother and the foetus. Despite the study's limited scope, the findings provided valuable insights and highlighted the need for future comprehensive cohort studies and extensive data in order to establish effective policies to protect vulnerable pregnant women from the dangers of heat stress and to promote reproductive health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adverse%20outcome" title="adverse outcome">adverse outcome</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20stress" title=" heat stress"> heat stress</a>, <a href="https://publications.waset.org/abstracts/search?q=interventions" title=" interventions"> interventions</a>, <a href="https://publications.waset.org/abstracts/search?q=physiological%20strain" title=" physiological strain"> physiological strain</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnant%20women" title=" pregnant women"> pregnant women</a> </p> <a href="https://publications.waset.org/abstracts/164030/occupational-heat-stress-related-adverse-pregnancy-outcome-a-pilot-study-in-south-india-workplaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164030.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">73</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">6</span> An Overview of PFAS Treatment Technologies with an In-Depth Analysis of Two Case Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arul%20Ayyaswami">Arul Ayyaswami</a>, <a href="https://publications.waset.org/abstracts/search?q=Vidhya%20Ramalingam"> Vidhya Ramalingam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Per- and polyfluoroalkyl substances (PFAS) have emerged as a significant environmental concern due to their ubiquity and persistence in the environment. Their chemical characteristics and adverse effects on human health demands more effective and sustainable solutions in remediation of the PFAS. The work presented here encompasses an overview of treatment technologies with two case studies that utilize effective approaches in addressing PFAS contaminated media. Currently the options for treatment of PFAS compounds include Activated carbon adsorption, Ion Exchange, Membrane Filtration, Advanced oxidation processes, Electrochemical treatment, and Precipitation and Coagulation. In the first case study, a pilot study application of colloidal activated carbon (CAC) was completed to address PFAS from aqueous film-forming foam (AFFF) used to extinguish a large fire. The pilot study was used to demonstrate the effectiveness of a CAC in situ permeable reactive barrier (PRB) in effectively stopping the migration of PFOS and PFOA, moving from the source area at high concentrations. Before the CAC PRB installation, an injection test using - fluorescein dye was conducted to determine the primary fracture-induced groundwater flow pathways. A straddle packer injection delivery system was used to isolate discrete intervals and gain resolution over the 70 feet saturated zone targeted for treatment. Flow rates were adjusted, and aquifer responses were recorded for each interval. The results from the injection test were used to design the pilot test injection plan using CAC PRB. Following the CAC PRB application, the combined initial concentration 91,400 ng/L of PFOS and PFOA were reduced to approximately 70 ng/L (99.9% reduction), after only one month following the injection event. The results demonstrate the remedy's effectiveness to quickly and safely contain high concentrations of PFAS in fractured bedrock, reducing the risk to downgradient receptors. The second study involves developing a reductive defluorination treatment process using UV and electron acceptor. This experiment indicates a significant potential in treatment of PFAS contaminated waste media such as landfill leachates. The technology also shows a promising way of tacking these contaminants without the need for secondary waste disposal or any additional pre-treatments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=per-%20and%20polyfluoroalkyl%20substances%20%28PFAS%29" title="per- and polyfluoroalkyl substances (PFAS)">per- and polyfluoroalkyl substances (PFAS)</a>, <a href="https://publications.waset.org/abstracts/search?q=colloidal%20activated%20carbon%20%28CAC%29" title=" colloidal activated carbon (CAC)"> colloidal activated carbon (CAC)</a>, <a href="https://publications.waset.org/abstracts/search?q=destructive%20PFAS%20treatment%20technology" title=" destructive PFAS treatment technology"> destructive PFAS treatment technology</a>, <a href="https://publications.waset.org/abstracts/search?q=aqueous%20film-forming%20foam%20%28AFFF%29" title=" aqueous film-forming foam (AFFF)"> aqueous film-forming foam (AFFF)</a> </p> <a href="https://publications.waset.org/abstracts/170680/an-overview-of-pfas-treatment-technologies-with-an-in-depth-analysis-of-two-case-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170680.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">60</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">5</span> Heat Stress a Risk Factor for Poor Maternal Health- Evidence from South India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vidhya%20Venugopal">Vidhya Venugopal</a>, <a href="https://publications.waset.org/abstracts/search?q=Rekha%20S."> Rekha S.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Climate change and the growing frequency of higher average temperatures and heat waves have detrimental health effects, especially for certain vulnerable groups with limited socioeconomic status (SES) or physiological capacity to adapt to or endure high temperatures. Little research has been conducted on the effects of heat stress on pregnant women and fetuses in tropical regions such as India. Very high ambient temperatures may worsen Adverse Pregnancy Outcomes (APOs) and are a major worry in the scenario of climate change. The relationship between rising temperatures and APO must be better understood in order to design more effective interventions. Methodology: We conducted an observational cohort study involving 865 pregnant women in various districts of Tamil Nadu districts between 2014 and 2021. Physiological Heat Strain Indicators (HSI) such as morning and evening Core Body Temperature (CBT) and Urine Specific Gravity (USG) were monitored using an infrared thermometer and refractometer, respectively. A validated, modified version of the HOTHAPS questionnaire was utilised to collect self-reported health symptoms. A follow-up was undertaken with the mothers to collect information regarding birth outcomes and APOs, such as spontaneous abortions, stillbirths, Preterm Birth (PTB), birth abnormalities, and Low Birth Weight (LBW). Major findings of the study: According to the findings of our study, ambient temperatures (mean WBGT°C) were substantially higher (>28°C) for approximately 46% of women performing moderate daily life activities. 82% versus 43% of these women experienced dehydration and heat-related complaints. 34% of women had USG >1.020, which is symptomatic of dehydration. APOs, which include spontaneous abortions, were prevalent at 2.2%, stillbirth/preterm birth/birth abnormalities were prevalent at 2.2%, and low birth weight was prevalent at 16.3%. With exposures to WBGT>28°C, the incidence of miscarriage or unexpected abortion rose by approximately 2.7 times (95% CI: 1.1-6.9). In addition, higher WBGT exposures were associated with a 1.4-fold increased risk of unfavorable birth outcomes (95% Confidence Interval [CI]: 1.02-1.09). The risk of spontaneous abortions was 2.8 times higher among women who conceived during the hotter months (February – September) compared to those women who conceived in the cooler months (October – January) (95% CI: 1.04-7.4). Positive relationships between ambient heat and APOs found in this study necessitate further exploration into the underlying factors for extensive cohort studies to generate information to enable the formulation of policies that can effectively protect these women against excessive heat stress for enhanced maternal and fetal health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20exposures" title="heat exposures">heat exposures</a>, <a href="https://publications.waset.org/abstracts/search?q=community" title=" community"> community</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnant%20women" title=" pregnant women"> pregnant women</a>, <a href="https://publications.waset.org/abstracts/search?q=physiological%20strain" title=" physiological strain"> physiological strain</a>, <a href="https://publications.waset.org/abstracts/search?q=adverse%20outcome" title=" adverse outcome"> adverse outcome</a>, <a href="https://publications.waset.org/abstracts/search?q=interventions" title=" interventions"> interventions</a> </p> <a href="https://publications.waset.org/abstracts/164023/heat-stress-a-risk-factor-for-poor-maternal-health-evidence-from-south-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164023.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">84</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">4</span> Development of a Table-Top Composite Wire Fabrication System for Additive Manufacturing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Krishna%20Nand">Krishna Nand</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Taufik"> Mohammad Taufik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fused Filament Fabrication (FFF) is one of the most popular additive manufacturing (AM) technology. In FFF technology, a wire form material (filament) is fed inside a heated chamber, where it gets converted into semi-solid form and extruded out of a nozzle to be deposited on the build platform to fabricate the part. FFF technology is expanding and covering the market at a very rapid rate, so the need of raw materials for 3D printing is also increasing. The cost of 3D printing is directly affected by filament cost. To make 3D printing more economic, a compact and portable filament/wire extrusion system is needed. Wire extrusion systems to extrude ordinary wire/filament made of a single material are available in the market. However, extrusion system to make a composite wire/filament are not available. Hence, in this study, initial efforts have been made to develop a table-top composite wire extruder. The developed system is consisted of mechanical parts, electronics parts, and a control system. A multiple channel hopper, extrusion screw, melting chamber and nozzle, cooling zone, and spool winder are some mechanical parts. While motors, heater, temperature sensor, cooling fans are some electronics parts, which are used to develop this system. A control board has been used to control the various process parameters like – temperature and speed of motors. For the production of composite wire/filament, two different materials could be fed through two channels of hopper, which will be mixed and carried to the heated zone by extrusion screw. The extrusion screw is rotated by a motor, and the speed of this motor will be controlled by the controller as per the requirement of material extrusion rate. In the heated zone, the material will melt with the help of a heating element and extruded out of the nozzle in the form of wire. The developed system occupies less floor space due to the vertical orientation of its heating chamber. It is capable to extrude ordinary filament as well as composite filament, which are compatible with 3D printers available in the market. Further, the developed system could be employed in the research and development of materials, processing, and characterization for 3D printer. The developed system presented in this study could be a better choice for hobbyists and researchers dealing with the fused filament fabrication process to reduce the 3D printing cost significantly by recycling the waste material into 3D printer feed material. Further, it could also be explored as a better alternative for filament production at the commercial level. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing" title="additive manufacturing">additive manufacturing</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=filament%20extrusion" title=" filament extrusion"> filament extrusion</a>, <a href="https://publications.waset.org/abstracts/search?q=pellet%20extrusion" title=" pellet extrusion"> pellet extrusion</a> </p> <a href="https://publications.waset.org/abstracts/139720/development-of-a-table-top-composite-wire-fabrication-system-for-additive-manufacturing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139720.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">168</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">3</span> Solid State Drive End to End Reliability Prediction, Characterization and Control</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Azman%20Abdul%20Latif">Mohd Azman Abdul Latif</a>, <a href="https://publications.waset.org/abstracts/search?q=Erwan%20Basiron"> Erwan Basiron</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A flaw or drift from expected operational performance in one component (NAND, PMIC, controller, DRAM, etc.) may affect the reliability of the entire Solid State Drive (SSD) system. Therefore, it is important to ensure the required quality of each individual component through qualification testing specified using standards or user requirements. Qualification testing is time-consuming and comes at a substantial cost for product manufacturers. A highly technical team, from all the eminent stakeholders is embarking on reliability prediction from beginning of new product development, identify critical to reliability parameters, perform full-blown characterization to embed margin into product reliability and establish control to ensure the product reliability is sustainable in the mass production. The paper will discuss a comprehensive development framework, comprehending SSD end to end from design to assembly, in-line inspection, in-line testing and will be able to predict and to validate the product reliability at the early stage of new product development. During the design stage, the SSD will go through intense reliability margin investigation with focus on assembly process attributes, process equipment control, in-process metrology and also comprehending forward looking product roadmap. Once these pillars are completed, the next step is to perform process characterization and build up reliability prediction modeling. Next, for the design validation process, the reliability prediction specifically solder joint simulator will be established. The SSD will be stratified into Non-Operating and Operating tests with focus on solder joint reliability and connectivity/component latent failures by prevention through design intervention and containment through Temperature Cycle Test (TCT). Some of the SSDs will be subjected to the physical solder joint analysis called Dye and Pry (DP) and Cross Section analysis. The result will be feedbacked to the simulation team for any corrective actions required to further improve the design. Once the SSD is validated and is proven working, it will be subjected to implementation of the monitor phase whereby Design for Assembly (DFA) rules will be updated. At this stage, the design change, process and equipment parameters are in control. Predictable product reliability at early product development will enable on-time sample qualification delivery to customer and will optimize product development validation, effective development resource and will avoid forced late investment to bandage the end-of-life product failures. Understanding the critical to reliability parameters earlier will allow focus on increasing the product margin that will increase customer confidence to product reliability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=e2e%20reliability%20prediction" title="e2e reliability prediction">e2e reliability prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=SSD" title=" SSD"> SSD</a>, <a href="https://publications.waset.org/abstracts/search?q=TCT" title=" TCT"> TCT</a>, <a href="https://publications.waset.org/abstracts/search?q=solder%20joint%20reliability" title=" solder joint reliability"> solder joint reliability</a>, <a href="https://publications.waset.org/abstracts/search?q=NUDD" title=" NUDD"> NUDD</a>, <a href="https://publications.waset.org/abstracts/search?q=connectivity%20issues" title=" connectivity issues"> connectivity issues</a>, <a href="https://publications.waset.org/abstracts/search?q=qualifications" title=" qualifications"> qualifications</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization%20and%20control" title=" characterization and control "> characterization and control </a> </p> <a href="https://publications.waset.org/abstracts/135316/solid-state-drive-end-to-end-reliability-prediction-characterization-and-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135316.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">174</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">2</span> Climate Change Implications on Occupational Health and Productivity in Tropical Countries: Study Results from India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vidhya%20Venugopal">Vidhya Venugopal</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeremiah%20Chinnadurai"> Jeremiah Chinnadurai</a>, <a href="https://publications.waset.org/abstracts/search?q=Rebekah%20A.%20I.%20Lucas"> Rebekah A.

The predicted rise in temperatures and heat events in the CC scenario have health implications on millions of workers in physically exerting jobs. The current health and productivity risks associated with heat exposures are characterized, future risk estimates as temperature rises and recommendations towards developing protective and preventive occupational health and safety guidelines for India are discussed. Methodology: Cross-sectional studies were conducted in several occupational sectors with workers engaged in moderate to heavy labor (n=1580). Quantitative data on heat exposures (WBGT°C), physiological heat strain indicators viz., Core temperature (CBT), Urine specific gravity (USG), Sweat rate (SwR) and qualitative data on heat-related health symptoms and productivity losses were collected. Data were analyzed for associations between heat exposures, health and productivity outcomes related to heat stress. Findings: Heat conditions exceeded the Threshold Limit Value (TLV) for safe manual work in 66% of the workers across several sectors (Avg.WBGT of 28.7°C±3.1°C). Widespread concerns about heat-related health outcomes (86%) were prevalent among workers exposed to high TLVs, with excessive sweating, fatigue and tiredness being commonly reported by workers. The heat stress indicators, core temperature (14%), Sweat rate (8%) and USG (9%), were above normal levels in the study population. A significant association was found between rise in Core Temperatures and WBGT exposures (p=0.000179) Elevated USG and SwR in the worker population indicate moderate dehydration, with potential risks of developing heat-related illnesses. In a steel industry with high heat exposures, an alarming 9% prevalence of kidney/urogenital anomalies was observed in a young workforce. Heat exposures above TLVs were associated with significantly increased odds of various adverse health outcomes (OR=2.43, 95% CI 1.88 to 3.13, p-value = <0.0001) and productivity losses (OR=1.79, 95% CI 1.32 to 2.4, p-value = 0.0002). Rough estimates for the number of workers who would be subjected to higher than TLV levels in the various RCP scenarios are RCP2.6 =79%, RCP4.5 & RCP6 = 81% and at RCP 8.5 = 85%. Rising temperatures due to CC has the capacity to further reduce already compromised health and productivity by subjecting the workers to increased heat exposures in the RCP scenarios are of concern for the country’s occupational health and economy. Conclusion: The findings of this study clearly identify that health protection from hot weather will become increasingly necessary in the Indian subcontinent and understanding the various adaptation techniques needs urgent attention. Further research with a multi-targeted approach to develop strategies for implementing interventions to protect the millions of workers is imperative. Approaches to include health aspects of climate change within sectoral and climate change specific policies should be encouraged, via a number of mechanisms, such as the “Health in All Policies” approach to avert adverse health and productivity consequences as climate change proceeds. <p class="card-text"><strong>Keywords:</strong> <a
