Xylenol Orange (XO) has been used as an indicator for selective detection of Sn (II) ions, by its immobilization on quaternized cellulose membrane. The effects of pH, reagent concentration and reaction time on the immobilization of XO have also been studied. The linear response, limit of detection, and interference of other metal ions have also been studied and no significant interference has been observed. The optical chemical sensor displayed good durability and short response time with negligible leaching of the reagent. <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=chemical%20sensor" title=" chemical sensor"> chemical sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metal%20ions" title=" heavy metal ions"> heavy metal ions</a>, <a href="https://publications.waset.org/abstracts/search?q=indicator%20immobilization" title=" indicator immobilization"> indicator immobilization</a> </p> <a href="https://publications.waset.org/abstracts/43826/indicator-immobilized-cellulose-based-optical-sensing-membrane-for-the-detection-of-heavy-metal-ions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43826.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">301</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> Burden of Dengue in Northern India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashutosh%20%20Biswas">Ashutosh Biswas</a>, <a href="https://publications.waset.org/abstracts/search?q=Poonam%20%20Coushic"> Poonam Coushic</a>, <a href="https://publications.waset.org/abstracts/search?q=Kalpana%20Baruah"> Kalpana Baruah</a>, <a href="https://publications.waset.org/abstracts/search?q=Paras%20Singla"> Paras Singla</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20C.%20Dhariwal"> A.

All India Institute of Medical Sciences, NVBDCP,WHO New Delhi, India Aim: This study was conducted to estimate the burden of dengue in capital region of India. Methodology:Seropositivity of Dengue for IgM Ab, NS1 Ag and IgG Ab were performed among the blood donors’ samples from blood bank, those who were coming to donate blood for the requirement of blood for the admitted patients in hospital. Blood samplles were collected through out the year to estimate seroprevalance of dengue with or without outbreak season. All the subjects were asymptomatic at the time of blood donation. Results: A total of 1558 donors were screened for the study. On the basis of inclusion/ exclusion criteria, we enrolled 1531subjects for the study.Twenty seven donors were excluded from the study, out of which 6 were detected HIV +ve, 11 were positive for HBsAg and 10 were found positive for HCV.Mean age was 30.51 ± 7.75 years.Of 1531subjects, 18 (1.18%) had a past history of typhoid fever, 28 (1.83%) had chikungunya fever, 9 (0.59%) had malaria and 43 subjects (2.81%) had a past history of symptomatic dengue infection.About 2.22% (34) of subjects were found to have sero-positive for NS1 Ag with a peak point prevalence of 7.14% in the month of October and sero-positive of IgM Ab was observed about 5.49% (84)with a peak point prevalence of 14.29% in the month of October. Sero-prevalnce of IgGwas detected in about 64.21% (983) of subjects. Conclusion: Acute asymptomatic dengue (NS1 Ag+ve) was observed in 7.14%, as the subjects were having no symptoms at the time of sampling. This group of subjects poses a potential public health threat for transmitting dengue infection through blood transfusion (TTI) in the community as evident by presence of active viral infection due to NS1Ag +VE. Therefore a policy may be implemented in the blood bank for testing NS1 Ag to look for active dengue infection for preventing dengue transmission through blood transfusion (TTI). Acute or Subacute dengue infection ( IgM Ab+ve) was observed from 5.49% to 14.29% which is a peak point prevalence in the month of October. About 64.21% of the population were immunized by natural dengue infection ( IgG Ab+ve) in theNorthern province of India. This might be helpful for implementing the dengue vaccine in a region. Blood samples in blood banks should be tested for dengue before transfusion to any other person to prevent transfusion transmitted dengue infection as we estimated upto 7.14% positivity of NS1 Ag in our study which indicates presence of dengue virus in blood donors’ samples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dengue%20Burden" title="Dengue Burden">Dengue Burden</a>, <a href="https://publications.waset.org/abstracts/search?q=Seroprevalance" title=" Seroprevalance"> Seroprevalance</a>, <a href="https://publications.waset.org/abstracts/search?q=Asymptomatic%20dengue" title=" Asymptomatic dengue"> Asymptomatic dengue</a>, <a href="https://publications.waset.org/abstracts/search?q=Dengue%20transmission%20through%20blood%20transfusion" title=" Dengue transmission through blood transfusion"> Dengue transmission through blood transfusion</a> </p> <a href="https://publications.waset.org/abstracts/121608/burden-of-dengue-in-northern-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121608.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">149</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> Stability Analysis of a Human-Mosquito Model of Malaria with Infective Immigrants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisha%20Budhwar">Nisha Budhwar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunita%20Daniel"> Sunita Daniel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we analyse the stability of the SEIR model of malaria with infective immigrants which was recently formulated by the authors.

The susceptible mosquito becomes infected after biting an infected person and remains infected till death.

A lot of approaches and investigators have been made in the study of calcium signalling in various cells to understand its mechanisms over recent decades. However, most of existing investigators have mainly focussed on the study of calcium signalling in various cells without paying attention to the dependence of calcium signalling on other chemical ions like inositol-1; 4; 5 triphosphate ions, etc. Some models for the independent study of calcium signalling and inositol-1; 4; 5 triphosphate signalling in various cells are present but very little attention has been paid by the researchers to study the interdependence of these two signalling processes in a cell. In this paper, we propose a coupled mathematical model to understand the interdependence of inositol-1; 4; 5 triphosphate dynamics and calcium dynamics in a myocyte cell. Such studies will provide the deeper understanding of various factors involved in calcium signalling in myocytes, which may be of great use to biomedical scientists for various medical applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calcium%20signalling" title="calcium signalling">calcium signalling</a>, <a href="https://publications.waset.org/abstracts/search?q=coupling" title=" coupling"> coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20difference%20method" title=" finite difference method"> finite difference method</a>, <a href="https://publications.waset.org/abstracts/search?q=inositol%201" title=" inositol 1"> inositol 1</a>, <a href="https://publications.waset.org/abstracts/search?q=4" title=" 4"> 4</a>, <a href="https://publications.waset.org/abstracts/search?q=5-triphosphate" title=" 5-triphosphate"> 5-triphosphate</a> </p> <a href="https://publications.waset.org/abstracts/68214/numerical-model-to-study-calcium-and-inositol-145-trisphosphate-dynamics-in-a-myocyte-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68214.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">292</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> Personal Factors and Career Adaptability in a Call Centre Work Environment: The Mediating Effects of Professional Efficacy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisha%20Harry">Nisha Harry</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study discussed in this article sought to assess whether a sense of professional efficacy mediates the relationship between personal factors and career adaptability. A quantitative cross-sectional survey approach was followed. A non–probability sample of (N = 409) of which predominantly early career and permanently employed black females in call centres in Africa participated in this study. In order to assess personal factors, the participants completed sense of meaningfulness and emotional intelligence measures. Measures of professional efficacy and career adaptability were also completed. The results of the mediational analysis revealed that professional efficacy significantly mediates the meaningfulness (sense of coherence) and career adaptability relationship, but not the emotional intelligence–career adaptability relationship. Call centre agents with professional efficacy are likely to be more work engaged as a result of their sense of meaningfulness and emotional intelligence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=call%20centre" title="call centre">call centre</a>, <a href="https://publications.waset.org/abstracts/search?q=professional%20efficacy" title=" professional efficacy"> professional efficacy</a>, <a href="https://publications.waset.org/abstracts/search?q=career%20adaptability" title=" career adaptability"> career adaptability</a>, <a href="https://publications.waset.org/abstracts/search?q=emotional%20intelligence" title=" emotional intelligence"> emotional intelligence</a> </p> <a href="https://publications.waset.org/abstracts/62810/personal-factors-and-career-adaptability-in-a-call-centre-work-environment-the-mediating-effects-of-professional-efficacy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62810.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">358</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Photoresponse of Epitaxial GaN Films Grown by Plasma-Assisted Molecular Beam Epitaxy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisha%20Prakash">Nisha Prakash</a>, <a href="https://publications.waset.org/abstracts/search?q=Kritika%20Anand"> Kritika Anand</a>, <a href="https://publications.waset.org/abstracts/search?q=Arun%20Barvat"> Arun Barvat</a>, <a href="https://publications.waset.org/abstracts/search?q=Prabir%20Pal"> Prabir Pal</a>, <a href="https://publications.waset.org/abstracts/search?q=Sonachand%20Adhikari"> Sonachand Adhikari</a>, <a href="https://publications.waset.org/abstracts/search?q=Suraj%20P.%20Khanna"> Suraj P.

Any midgap defect states in the epitaxial grown film have a direct influence on the photodetectors responsivity. The proportion of the midgap defect states can be controlled by the growth parameters. To study this we have grown high quality epitaxial GaN films on MOCVD- grown GaN template using plasma-assisted molecular beam epitaxy (PAMBE) with different growth parameters. Optical and electrical properties of the films were characterized by room temperature photoluminescence and photoconductivity measurements, respectively. The observed persistent photoconductivity behaviour is proportional to the yellow luminescence (YL) and the absolute responsivity has been found to decrease with decreasing YL. The results will be discussed in more detail later. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gallium%20nitride" title="gallium nitride">gallium nitride</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma-assisted%20molecular%20beam%20epitaxy" title=" plasma-assisted molecular beam epitaxy"> plasma-assisted molecular beam epitaxy</a>, <a href="https://publications.waset.org/abstracts/search?q=photoluminescence" title=" photoluminescence"> photoluminescence</a>, <a href="https://publications.waset.org/abstracts/search?q=photoconductivity" title=" photoconductivity"> photoconductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=persistent%20photoconductivity" title=" persistent photoconductivity"> persistent photoconductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=yellow%20luminescence" title=" yellow luminescence"> yellow luminescence</a> </p> <a href="https://publications.waset.org/abstracts/29135/photoresponse-of-epitaxial-gan-films-grown-by-plasma-assisted-molecular-beam-epitaxy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29135.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">317</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> Regeneration of Plantlets via Direct Somatic Embryogenesis from Different Explants of Murraya koenigii</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisha%20Khatik">Nisha Khatik</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramesh%20Joshi"> Ramesh Joshi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An in vitro plant regeneration system was developed via direct somatic embryogenesis from different seedling explants of an important medicinal plant Murraya koenigii (L) Spreng. Cotyledons (COT), Hypocotyle (HYP)(10 to 15 mm) and Root (RT) segments (10 to 20 mm) were excised from 60 days old seedlings as explants. The somatic embryos induction was achieved on MS basal medium augmented with different concentrations of BAP 1.33 to 8.40 µM and TDZ 1.08 to 9.82 µM. The globular embryos originated from cut ends and entire surface of the root, hypocotyle explants and margins of cotyledons within 30-40days. The percentage of somatic embryos induction per explant was significantly higher in HYP explants (94.21±5.77%) in the MS basal medium supplemented with 6.20 µM BAP and 8.64 µM TDZ. The highest rate of conversion of torpedo, heart and cotyledonary stages from globular stage was obtained in MS medium supplemented with 8.64 µM TDZ. The matured somatic embryos were transferred to the MS basal medium without PGRs. Highest 88% of the matured embryos were germinated on transfer to the PGR free medium where they grew for a further 3-4 weeks. Out of seventy six hardened plants seventy (92%) plantlets were found healthy under field conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Murraya%20koenigii" title="Murraya koenigii">Murraya koenigii</a>, <a href="https://publications.waset.org/abstracts/search?q=somatic%20embryogenesis" title=" somatic embryogenesis"> somatic embryogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=thidiazuron" title=" thidiazuron"> thidiazuron</a>, <a href="https://publications.waset.org/abstracts/search?q=regeneration" title=" regeneration"> regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=rutaceae" title=" rutaceae"> rutaceae</a> </p> <a href="https://publications.waset.org/abstracts/20190/regeneration-of-plantlets-via-direct-somatic-embryogenesis-from-different-explants-of-murraya-koenigii" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20190.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">427</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> Spectroscopic Study of Eu³⁺ Ions Doped Potassium Lead Alumino Borate Glasses for Photonic Device Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisha%20Deopa">Nisha Deopa</a>, <a href="https://publications.waset.org/abstracts/search?q=Allam%20Srinivasa%20Rao"> Allam Srinivasa Rao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Quaternary potassium lead alumino borate (KPbAlB) glasses doped with different concentration of Eu³⁺ ions have been synthesized by melt quench technique and characterized by X-ray diffraction (XRD), Scanning electron microscope (SEM), Photoluminescence (PL), Time-resolved photoluminescence (TRPL) and CIE-chromaticity co-ordinates to study their luminescence behavior. A broad hump was observed in XRD spectrum confirms glassy nature of as-prepared glasses. By using Judd-Ofelt (J-O) theory, various radiative parameters for the prominent fluorescent levels of Eu³⁺ have been investigated. The intense emission peak was observed at 613 nm (⁵D₀→⁷F₂) under 393 nm excitation, matches well with the excitation of n-UV LED chips. The decay profiles observed for ⁵D₀ level were exponential for lower Eu³⁺ ion concentration while non-exponential for higher concentration, which may be due to efficient energy transfer between Eu³⁺-Eu³⁺ through cross relaxation and subsequent quenching observed. From the emission cross-sections, branching ratios, quantum efficiency and CIE coordinates, it was concluded that 7 mol % of Eu³⁺ ion concentration (glass B) is optimum in KPbAlB glasses for photonic device application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20transfer" title="energy transfer">energy transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=glasses" title=" glasses"> glasses</a>, <a href="https://publications.waset.org/abstracts/search?q=J-O%20parameters" title=" J-O parameters"> J-O parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=photoluminescence" title=" photoluminescence"> photoluminescence</a> </p> <a href="https://publications.waset.org/abstracts/88460/spectroscopic-study-of-eu3-ions-doped-potassium-lead-alumino-borate-glasses-for-photonic-device-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88460.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">163</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> Spectroscopic Investigations of Nd³⁺ Doped Lithium Lead Alumino Borate Glasses for 1.06μM Laser Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisha%20Deopa">Nisha Deopa</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20S.%20Rao"> A. S.

From the absorption spectra, Judd-Ofelt intensity parameters along with various spectroscopic parameters have been estimated. The emission spectra recorded for the as-prepared glasses under investigation exhibit two emission transitions, ⁴F₃/₂→⁴I₁₁/₂ (1063 nm) and ⁴F₃/₂→⁴I₉/₂ (1350 nm) for which radiative parameters have been evaluated. The emission intensity increases with increase in Nd³⁺ ion concentration up to 1 mol %, and beyond concentration quenching took place. The decay profile shows single exponential nature for lower Nd³⁺ ions concentration and non-exponential for higher concentration. To elucidate the nature of energy transfer process, non-exponential decay curves were well fitted to Inokuti-Hirayama model. The relatively high values of emission cross-section, branching ratio, lifetimes and quantum efficiency suggest that 1.0 mol% of Nd³⁺ in LiPbAlB glasses is aptly suitable to generate lasing action in NIR region at 1063 nm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20transfer" title="energy transfer">energy transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=glasses" title=" glasses"> glasses</a>, <a href="https://publications.waset.org/abstracts/search?q=J-O%20parameters" title=" J-O parameters"> J-O parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=photoluminescence" title=" photoluminescence"> photoluminescence</a> </p> <a href="https://publications.waset.org/abstracts/78288/spectroscopic-investigations-of-nd3-doped-lithium-lead-alumino-borate-glasses-for-106mm-laser-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78288.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">189</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> The Social Construction of the Family among the Survivors of Sex Trafficking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisha%20James">Nisha James</a>, <a href="https://publications.waset.org/abstracts/search?q=Shubha%20Ranganathan"> Shubha Ranganathan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sex trafficking is a traumatic ongoing process which includes human rights violations against the victims. Majority of the trafficked individuals in India are from families with low socioeconomic status, from rural areas, unmarried or married off at a very young age. Many of the sex trafficked feel that it is necessary to make sacrifices, for the benefit of their families. The combination of these cultural family values with the stigma of rape and prostitution are manipulated and used as a tool in the abuse of power against the sex trafficked. The rescue, rehabilitation and reintegration of these individuals are usually difficult due to the stigma and social exclusion that they face. In these circumstances, social support is very effective in social inclusion of these individuals. The present study was a qualitative one, using semi-structured interviews with 29 Indian survivors of sex trafficking and a few sex workers. Thematic analysis was done on the data derived from the semi-structured interviews. The major findings indicate that the family can be seen as both the ‘cause’ for being sex trafficked, and the factor in victim continuing to be sex trafficked. At the same time, it can also become a driver for getting rescued, rehabilitated and reintegrated. The study also explores the social construction about ‘family’ among the survivors of sex trafficking, reflecting on who they refer to as ‘family’, what they mean by the term ‘family’ and how these families emerge. Therefore the analytic concept of ‘family’ is a crucial element in sex trafficking and cannot be defined only in terms of its conventional definition of a basic unit of society. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sex-trafficking" title="sex-trafficking">sex-trafficking</a>, <a href="https://publications.waset.org/abstracts/search?q=survivor" title=" survivor"> survivor</a>, <a href="https://publications.waset.org/abstracts/search?q=family" title=" family"> family</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20construction" title=" social construction"> social construction</a> </p> <a href="https://publications.waset.org/abstracts/21581/the-social-construction-of-the-family-among-the-survivors-of-sex-trafficking" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21581.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">591</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> ARCS Model for Enhancing Intrinsic Motivation in Learning Biodiversity Subjects: A Case Study of Tertiary Level Students in Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Nisha%20Musa">Nadia Nisha Musa</a>, <a href="https://publications.waset.org/abstracts/search?q=Nur%20Atirah%20Hasmi"> Nur Atirah Hasmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasnun%20Nita%20Ismail"> Hasnun Nita Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Zulfadli%20Mahfodz"> Zulfadli Mahfodz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Malaysian Education System, subject related to biodiversity has started in the curriculum from Foundation Study until tertiary education. Biodiversity become the focus of attention due to awareness on global warming which potentially leads to a loss of biodiversity. A loss in biodiversity means a loss in medicinal discoveries and reduces food supply. It is of great important to ensure that young generations become aware of biodiversity conservation. The more interactive approaches are needed to build society with a high awareness for biodiversity conservation. To address this challenge, the goal of this study is to enhance intrinsic motivation of biological students via ARCS model of instruction. Self-access learning materials such as tutorial, module and fieldwork were designed with ARCS elements to a sample size of 70 university students from the beginning of the semester. Both paper and online surveys were used to collect data from the respondents. The results showed that elements of attention, relevance, confidence and satisfaction have a positive impact on intrinsic motivation of students and their academic performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intrinsic%20motivation" title="intrinsic motivation">intrinsic motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=ARCS%20model%20of%20instruction" title=" ARCS model of instruction"> ARCS model of instruction</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title=" biodiversity"> biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=self-access%20learning" title=" self-access learning"> self-access learning</a> </p> <a href="https://publications.waset.org/abstracts/57479/arcs-model-for-enhancing-intrinsic-motivation-in-learning-biodiversity-subjects-a-case-study-of-tertiary-level-students-in-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57479.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">222</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> Development of 3D Neck Muscle to Analyze the Effect of Active Muscle Contraction in Whiplash Injury</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisha%20Nandlal%20Sharma">Nisha Nandlal Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Julaluk%20Carmai"> Julaluk Carmai</a>, <a href="https://publications.waset.org/abstracts/search?q=Saiprasit%20Koetniyom"> Saiprasit Koetniyom</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernd%20Markert"> Bernd Markert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Whiplash Injuries are mostly experienced in car accidents. Symptoms of whiplash are commonly reported in studies, neck pain and headaches are two most common symptoms observed. The whiplash Injury mechanism is poorly understood. In present study, hybrid neck muscle model were developed with a combination of solid tetrahedral elements and 1D beam elements. Solid tetrahedral elements represents passive part of the muscle whereas, 1D beam elements represents active part. To simulate the active behavior of the muscle, Hill-type muscle model was applied to beam elements. To simulate non-linear passive properties of muscle, solid elements were modeled with rubber/foam material model. Some important muscles were then inserted into THUMS (Total Human Model for Safety) THUMS was given a boundary conditions similar to experimental tests. The model was exposed to 4g and 7g rear impacts as these load impacts are close to low speed impacts causing whiplash. The effect of muscle activation level on occupant kinematics during whiplash was analyzed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20model" title="finite element model">finite element model</a>, <a href="https://publications.waset.org/abstracts/search?q=muscle%20activation" title=" muscle activation"> muscle activation</a>, <a href="https://publications.waset.org/abstracts/search?q=THUMS" title=" THUMS"> THUMS</a>, <a href="https://publications.waset.org/abstracts/search?q=whiplash%20injury%20mechanism" title=" whiplash injury mechanism"> whiplash injury mechanism</a> </p> <a href="https://publications.waset.org/abstracts/42975/development-of-3d-neck-muscle-to-analyze-the-effect-of-active-muscle-contraction-in-whiplash-injury" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42975.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">22</span> Adsorption and Kinetic Studies on Removal of NH3-N from Wastewater onto 2 Different Nanoparticles Loaded Coconut Coir</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khushboo%20Bhavsar">Khushboo Bhavsar</a>, <a href="https://publications.waset.org/abstracts/search?q=Nisha%20K.%20Shah"> Nisha K.

Adsorption behavior of ammoniacal nitrogen from wastewater using the nanoparticles loaded coconut coir was investigated in the present work. Manganese Oxide (MnO2) and Zinc Oxide (ZnO) nanoparticles were prepared and used for the further adsorption study. Manganese nanoparticles loaded coconut coir (MNLCC) and Zinc nanoparticles loaded coconut coir (ZNLCC) were prepared via a simple method and was fully characterized. The properties of both MNLCC and ZNLCC were characterized by Scanning electron microscopy, Fourier Transform Infrared Spectroscopy and X-ray diffraction. Adsorption characteristics were studied using batch technique considering various parameters like pH, adsorbent dosage, time, temperature and agitation time. The NH3-N adsorption process for MNLCC and ZNLCC was thoroughly studied from both kinetic and equilibrium isotherm view-points. The results indicated that the adsorption efficiency of ZNLCC was better when compared to MNLCC. The adsorption kinetics at different experimental conditions showed that second order kinetic model best fits ensuring the monovalent binding sites existing in the present experimental system. The outcome of the entire study suggests that the ZNLCC can be a smart option for the treatment of the ammoniacal nitrogen containing wastewater. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ammoniacal%20nitrogen" title="ammoniacal nitrogen">ammoniacal nitrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=MnO2" title=" MnO2"> MnO2</a>, <a href="https://publications.waset.org/abstracts/search?q=Nanoparticles" title=" Nanoparticles"> Nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=ZnO" title=" ZnO"> ZnO</a> </p> <a href="https://publications.waset.org/abstracts/40523/adsorption-and-kinetic-studies-on-removal-of-nh3-n-from-wastewater-onto-2-different-nanoparticles-loaded-coconut-coir" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40523.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">356</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> A Comprehensive Review on Health Hazards and Challenges for Microbial Remediation of Persistent Organic Pollutants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisha%20Gaur">Nisha Gaur</a>, <a href="https://publications.waset.org/abstracts/search?q=K.Narasimhulu"> K.Narasimhulu</a>, <a href="https://publications.waset.org/abstracts/search?q=Pydi%20Setty%20Yelamarthy"> Pydi Setty Yelamarthy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Persistent organic pollutants (POPs) have become a great concern due to their toxicity, transformation and bioaccumulation property. Therefore, this review highlights the types, sources, classification health hazards and mobility of organochlorine pesticides, industrial chemicals and their by-products. Moreover, with the signing of Aarhus and Stockholm convention on POPs there is an increased demand to identify and characterise such chemicals from industries and environment which are toxic in nature or to existing biota. Due to long life, persistent nature they enter into body through food and transfer to all tropic levels of ecological unit. In addition, POPs are lipophilic in nature and accumulate in lipid-containing tissues and organs which further indicates the adverse symptoms after the threshold limit. Though, several potential enzymes are reported from various categories of microorganism and their interaction with POPs may break down the complex compounds either through biodegradation, biostimulation or bioaugmentation process, however technological advancement and human activities have also indicated to explore the possibilities for the role of genetically modified organisms and metagenomics and metabolomics. Though many studies have been done to develop low cost, effective and reliable method for detection, determination and removal of ultra-trace concentration of persistent organic pollutants (POPs) but due to insufficient knowledge and non-feasibility of technique, the safe management of POPs is still a global challenge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=persistent%20organic%20pollutants" title="persistent organic pollutants">persistent organic pollutants</a>, <a href="https://publications.waset.org/abstracts/search?q=bioaccumulation" title=" bioaccumulation"> bioaccumulation</a>, <a href="https://publications.waset.org/abstracts/search?q=biostimulation" title=" biostimulation"> biostimulation</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20remediation" title=" microbial remediation"> microbial remediation</a> </p> <a href="https://publications.waset.org/abstracts/76893/a-comprehensive-review-on-health-hazards-and-challenges-for-microbial-remediation-of-persistent-organic-pollutants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76893.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">299</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">20</span> Evaluation of Ceres Wheat and Rice Model for Climatic Conditions in Haryana, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mamta%20Rana">Mamta Rana</a>, <a href="https://publications.waset.org/abstracts/search?q=K.%20K.%20Singh"> K.

The CERES-Wheat & Rice vs. 4.6 DSSAT was calibrated and evaluated for one of the major producers of wheat and rice state- Haryana, India. The simulation runs were made under irrigated conditions and three fertilizer applications dose of N-P-K to estimate crop yield and other growth parameters along with the phenological development of the crop. The genetic coefficients derived by iteratively manipulating the relevant coefficients that characterize the phenological process of wheat and rice crop to the best fit match between the simulated and observed anthesis, physological maturity and final grain yield. The model validated by plotting the simulated and remote sensing derived LAI. LAI product from remote sensing provides the edge of spatial, timely and accurate assessment of crop. For validating the yield and yield components, the error percentage between the observed and simulated data was calculated. The analysis shows that the model can be used to simulate crop yield and yield components for wheat and rice cultivar under different management practices. During the validation, the error percentage was less than 10%, indicating the utility of the calibrated model for climate risk assessment in the selected region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=simulation%20model" title="simulation model">simulation model</a>, <a href="https://publications.waset.org/abstracts/search?q=CERES-wheat%20and%20rice%20model" title=" CERES-wheat and rice model"> CERES-wheat and rice model</a>, <a href="https://publications.waset.org/abstracts/search?q=crop%20yield" title=" crop yield"> crop yield</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20coefficient" title=" genetic coefficient"> genetic coefficient</a> </p> <a href="https://publications.waset.org/abstracts/67021/evaluation-of-ceres-wheat-and-rice-model-for-climatic-conditions-in-haryana-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67021.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">305</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">19</span> Nanoparticle Based Green Inhibitor for Corrosion Protection of Zinc in Acidic Medium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neha%20Parekh">Neha Parekh</a>, <a href="https://publications.waset.org/abstracts/search?q=Divya%20Ladha"> Divya Ladha</a>, <a href="https://publications.waset.org/abstracts/search?q=Poonam%20Wadhwani"> Poonam Wadhwani</a>, <a href="https://publications.waset.org/abstracts/search?q=Nisha%20Shah"> Nisha Shah </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nano scaled materials have attracted tremendous interest as corrosion inhibitor due to their high surface area on the metal surfaces. It is well known that the zinc oxide nanoparticles have higher reactivity towards aqueous acidic solution. This work presents a new method to incorporate zinc oxide nanoparticles with white sesame seeds extract (nano-green inhibitor) for corrosion protection of zinc in acidic medium. The morphology of the zinc oxide nanoparticles was investigated by TEM and DLS. The corrosion inhibition efficiency of the green inhibitor and nano-green inhibitor was determined by Gravimetric and electrochemical impedance spectroscopy (EIS) methods. Gravimetric measurements suggested that nano-green inhibitor is more effective than green inhibitor. Furthermore, with the increasing temperature, inhibition efficiency increases for both the inhibitors. In addition, it was established the Temkin adsorption isotherm fits well with the experimental data for both the inhibitors. The effect of temperature and Temkin adsorption isotherm revealed Chemisorption mechanism occurring in the system. The activation energy (Ea) and other thermodynamic parameters for inhibition process were calculated. The data of EIS showed that the charge transfer controls the corrosion process. The surface morphology of zinc metal (specimen) in absence and presence of green inhibitor and nano-green inhibitor were performed using Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM) techniques. The outcomes indicated a formation of a protective layer over zinc metal (specimen). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrosion" title="corrosion">corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20inhibitor" title=" green inhibitor"> green inhibitor</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title=" nanoparticles"> nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc" title=" zinc "> zinc </a> </p> <a href="https://publications.waset.org/abstracts/40529/nanoparticle-based-green-inhibitor-for-corrosion-protection-of-zinc-in-acidic-medium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40529.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">454</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Building Collapse: Factors and Resisting Mechanisms: A Review of Case Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Genevieve%20D.%20Fernandes">Genevieve D.

But even after taking all precautions, it is impossible to guarantee safety and collapse because of several unforeseen reasons like faulty constructions, design errors, overloading, soil liquefaction, gas explosion, material degradation, terrorist attacks and economic factors also contributing to the collapse. It is also uneconomical to design the structure for unforeseen events unless they have a reasonable chance of occurrence. In order to ensure safety and prevent collapse, many guidelines have been framed by local bodies and government authorities in many countries like the United States Department of Defence (DOD), United States General Service Administration (GSA) and Euro-Codes in European Nations. Some other practices are followed to incorporate redundancies in the structure like detailing, ductile designs, tying of elements at particular locations, and provision of hinges and interconnections. It is also to be admitted that a full-proof safe design structure for accidental events cannot be prepared and implemented as it is uneconomical and the chances of such occurrences are less. This paper reviews past case studies of the collapse of structures with the aim of developing an understanding of the collapse mechanism. This study will definitely help to bring about a detailed improvement in the design to maximise the quality of the construction at a minimal cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=unforeseen%20factors" title="unforeseen factors">unforeseen factors</a>, <a href="https://publications.waset.org/abstracts/search?q=progressive%20collapse" title=" progressive collapse"> progressive collapse</a>, <a href="https://publications.waset.org/abstracts/search?q=collapse%20resisting%20mechanisms" title=" collapse resisting mechanisms"> collapse resisting mechanisms</a>, <a href="https://publications.waset.org/abstracts/search?q=column%20removal%20scenario" title=" column removal scenario"> column removal scenario</a> </p> <a href="https://publications.waset.org/abstracts/152573/building-collapse-factors-and-resisting-mechanisms-a-review-of-case-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152573.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">137</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> Photoluminescence and Energy Transfer Studies of Dy3+ Ions Doped Lithium Lead Alumino Borate Glasses for W-LED and Laser Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisha%20Deopa">Nisha Deopa</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20S.%20Rao"> A.

As Dy3+ ions concentration increases, decay profile changes from exponential to non-exponential through energy transfer mechanism (ETM) in turn decreasing experimental lifetime. In order to investigate the nature of ETM, non-exponential decay curves were fitted to Inkuti–Hirayama (I-H) model which further confirms dipole-dipole interaction. Among all the emission transition, 4F9/2 6H15/2 transition (483 nm) is best suitable for lasing potentialities. By exciting titled glasses in n-UV to blue regions, CIE chromaticity coordinates and Correlated Color Temperature (CCT) were calculated to understand their capability in cool white light generation. From the evaluated radiative parameters, CIE co-ordinates, quantum efficiency and confocal images it was observed that glass B (0.5 mol%) is a potential candidate for developing w-LEDs and lasers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20transfer" title="energy transfer">energy transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=glasses" title=" glasses"> glasses</a>, <a href="https://publications.waset.org/abstracts/search?q=J-O%20parameters" title=" J-O parameters"> J-O parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=photoluminescence" title=" photoluminescence"> photoluminescence</a> </p> <a href="https://publications.waset.org/abstracts/68473/photoluminescence-and-energy-transfer-studies-of-dy3-ions-doped-lithium-lead-alumino-borate-glasses-for-w-led-and-laser-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68473.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">215</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> Traumatic Brain Injury Induced Lipid Profiling of Lipids in Mice Serum Using UHPLC-Q-TOF-MS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seema%20Dhariwal">Seema Dhariwal</a>, <a href="https://publications.waset.org/abstracts/search?q=Kiran%20Maan"> Kiran Maan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruchi%20Baghel"> Ruchi Baghel</a>, <a href="https://publications.waset.org/abstracts/search?q=Apoorva%20Sharma"> Apoorva Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Poonam%20Rana"> Poonam Rana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Traumatic brain injury (TBI) is defined as the temporary or permanent alteration in brain function and pathology caused by an external mechanical force. It represents the leading cause of mortality and morbidity among children and youth individuals. Various models of TBI in rodents have been developed in the laboratory to mimic the scenario of injury. Blast overpressure injury is common among civilians and military personnel, followed by accidents or explosive devices. In addition to this, the lateral Controlled cortical impact (CCI) model mimics the blunt, penetrating injury. Method: In the present study, we have developed two different mild TBI models using blast and CCI injury. In the blast model, helium gas was used to create an overpressure of 130 kPa (±5) via a shock tube, and CCI injury was induced with an impact depth of 1.5mm to create diffusive and focal injury, respectively. C57BL/6J male mice (10-12 weeks) were divided into three groups: (1) control, (2) Blast treated, (3) CCI treated, and were exposed to different injury models. Serum was collected on Day1 and day7, followed by biphasic extraction using MTBE/Methanol/Water. Prepared samples were separated on Charged Surface Hybrid (CSH) C18 column and acquired on UHPLC-Q-TOF-MS using ESI probe with inhouse optimized parameters and method. MS peak list was generated using Markerview TM. Data were normalized, Pareto-scaled, and log-transformed, followed by multivariate and univariate analysis in metaboanalyst. Result and discussion: Untargeted profiling of lipids generated extensive data features, which were annotated through LIPID MAPS® based on their m/z and were further confirmed based on their fragment pattern by LipidBlast. There is the final annotation of 269 features in the positive and 182 features in the negative mode of ionization. PCA and PLS-DA score plots showed clear segregation of injury groups to controls. Among various lipids in mild blast and CCI, five lipids (Glycerophospholipids {PC 30:2, PE O-33:3, PG 28:3;O3 and PS 36:1 } and fatty acyl { FA 21:3;O2}) were significantly altered in both injury groups at Day 1 and Day 7, and also had VIP score >1. Pathway analysis by Biopan has also shown hampered synthesis of Glycerolipids and Glycerophospholipiods, which coincides with earlier reports. It could be a direct result of alteration in the Acetylcholine signaling pathway in response to TBI. Understanding the role of a specific class of lipid metabolism, regulation and transport could be beneficial to TBI research since it could provide new targets and determine the best therapeutic intervention. This study demonstrates the potential lipid biomarkers which can be used for injury severity diagnosis and identification irrespective of injury type (diffusive or focal). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LipidBlast" title="LipidBlast">LipidBlast</a>, <a href="https://publications.waset.org/abstracts/search?q=lipidomic%20biomarker" title=" lipidomic biomarker"> lipidomic biomarker</a>, <a href="https://publications.waset.org/abstracts/search?q=LIPID%20MAPS%C2%AE" title=" LIPID MAPS®"> LIPID MAPS®</a>, <a href="https://publications.waset.org/abstracts/search?q=TBI" title=" TBI"> TBI</a> </p> <a href="https://publications.waset.org/abstracts/151561/traumatic-brain-injury-induced-lipid-profiling-of-lipids-in-mice-serum-using-uhplc-q-tof-ms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151561.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">113</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">15</span> Influence of Physicochemical Water Quality Parameters on Abundance of Aquatic Insects in Rivers of Perak, Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nur%20Atirah%20Hasmi">Nur Atirah Hasmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Nisha%20Musa"> Nadia Nisha Musa</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasnun%20Nita%20Ismail"> Hasnun Nita Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Zulfadli%20Mahfodz"> Zulfadli Mahfodz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effect of water quality parameters on the abundance of aquatic insects has been studied in Batu Berangkai, Dipang, Kuala Woh and Lata Kinjang Rivers, Perak, northern peninsular Malaysia. The focuses are to compare the abundance of aquatic insects in each sampling areas and to investigate the physical and chemical factors (water temperature, depth of water, canopy, water velocity, pH value, and dissolved oxygen) on the abundance of aquatic insects. The samples and data were collected by using aquatic net and multi-probe parameter. Physical parameters; water velocity, water temperature, depth, canopy cover, and two chemical parameters; pH value and dissolved oxygen have been measured in situ and recorded. A total of 631 individuals classified into 6 orders and 18 families of aquatic insects were identified from four sampling sites. The largest percentage of samples collected is from order Plecoptera 35.8%, followed by Ephemeroptera 32.6%, Trichoptera 17.0%, Hemiptera 8.1%, Coleoptera 4.8%, and the least is Odonata 1.7%. The aquatic insects collected from Dipang River have the highest abundance of 273 individuals from 6 orders and 13 families and the least insects trapped at Lata Kinjang which only have 64 individuals from 5 orders and 6 families. There is significant association between different sampling areas and abundance of aquatic insects (p<0.05). High abundance of aquatic insects was found in higher water temperature, low water velocity, deeper water, low pH, high amount of dissolved oxygen, and the area that is not covered by canopy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aquatic%20insect" title="aquatic insect">aquatic insect</a>, <a href="https://publications.waset.org/abstracts/search?q=physicochemical%20parameter" title=" physicochemical parameter"> physicochemical parameter</a>, <a href="https://publications.waset.org/abstracts/search?q=river" title=" river"> river</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality"> water quality</a> </p> <a href="https://publications.waset.org/abstracts/57477/influence-of-physicochemical-water-quality-parameters-on-abundance-of-aquatic-insects-in-rivers-of-perak-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57477.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">216</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">14</span> Film Review of 'Heroic Saviours and Survivors': The Representation of Sex Trafficking in Popular Films in India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisha%20James">Nisha James</a>, <a href="https://publications.waset.org/abstracts/search?q=Shubha%20Ranganathan"> Shubha Ranganathan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the most poignant forms of organized crime against women, which has rarely made it to the world of Indian cinema, is that of sex trafficking, i.e. the forcible involvement of women in the sex trade through fraud or coercion (Hughes, 2005). In the space of Indian cinema, much of the spotlight has been on the sensational drug trafficking and gang mafia of Bombay. During our research on sex trafficking, the rehabilitated women interviewed often expressed strong criticism about mass media’s naive portrayal of prostitutes as money-minting, happy and sexually driven women. They argued that this unrealistic portrayal ignored the fact that this was not a reality for the majority of trafficked women. Given the gravity of sex trafficking as a human rights issue, it is, therefore, refreshing to see three recent films on sex trafficking in Indian Languages – Naa Bangaaru Talli (2014, Telugu), Mardaani (2014, Hindi) and Lakshmi (2014, Hindi). This paper reviews these three films to explore the portrayal of the everyday reality of trafficking for women. Film analysis was used to understand the representation of psychological issues in the media. The strength of these movies starts with their inspirations which are of true stories and that they are all aimed at bringing awareness about the issue of sex trafficking, which is a rising social evil in Indian society though none of the three films move to portray the next phase of rehabilitation and reintegration of victims, which is a very complex and important process in the life of a survivor. According to findings, survivors of sex trafficking find the rehabilitation and reintegration into society to be a slow and tough part of their life as they continuously face stigma and social exclusion and have to strive to live against all odds of non-acceptance starting from their family. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=film%20review" title="film review">film review</a>, <a href="https://publications.waset.org/abstracts/search?q=Indian%20films" title=" Indian films"> Indian films</a>, <a href="https://publications.waset.org/abstracts/search?q=sex%20trafficking" title=" sex trafficking"> sex trafficking</a>, <a href="https://publications.waset.org/abstracts/search?q=survivors" title=" survivors"> survivors</a> </p> <a href="https://publications.waset.org/abstracts/22383/film-review-of-heroic-saviours-and-survivors-the-representation-of-sex-trafficking-in-popular-films-in-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22383.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">440</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">13</span> Screening of Different Native Genotypes of Broadleaf Mustard against Different Diseases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisha%20Thapa">Nisha Thapa</a>, <a href="https://publications.waset.org/abstracts/search?q=Ram%20Prasad%20Mainali"> Ram Prasad Mainali</a>, <a href="https://publications.waset.org/abstracts/search?q=Prakriti%20Chand"> Prakriti Chand</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Broadleaf mustard is a commercialized leafy vegetable of Nepal. However, its utilization is hindered in terms of production and productivity due to the high intensity of insects, pests, and diseases causing great loss. The plant protection part of the crop’s disease and damage intensity has not been studied much from research perspectives in Nepal. The research aimed to evaluate broadleaf mustard genotypes for resistance against different diseases. A total of 35 native genotypes of broadleaf mustard were screened at weekly intervals by scoring the plants for ten weeks. Five different diseases, such as Rhizoctonia root rot, Alternaria blight, black rot, turnip mosaic virus disease, and white rust, were reported from the broad leaf mustard genotypes. Out of 35 genotypes, 23 genotypes were found with very high Rhizoctonia Root Rot severity, whereas 8 genotypes showed very high Alternaria blight severity. Likewise, 3 genotypes were found with high Black rot severity, and 1 genotype was found with very high Turnip mosaic virus disease incidence. Similarly, 2 genotypes were found to have very high White rust severity. Among the disease of national importance, Rhizoctonia root rot was found to be the most severe disease with the greatest loss. Broadleaf mustard genotypes like Rato Rayo, CO 1002, and CO 11007 showed average to the high level of field resistance; therefore, these genotypes should be used, conserved, and stored in a mustard improvement program as the disease resistance quality or susceptibility of these genotypes can be helpful for seed producing farmers, companies and other stakeholders through varietal improvement and developmental works that further aids in sustainable disease management of the vegetable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genotype" title="genotype">genotype</a>, <a href="https://publications.waset.org/abstracts/search?q=disease%20resistance" title=" disease resistance"> disease resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=Rhizoctonia%20root%20rot%20severity" title=" Rhizoctonia root rot severity"> Rhizoctonia root rot severity</a>, <a href="https://publications.waset.org/abstracts/search?q=varietal%20improvement" title=" varietal improvement"> varietal improvement</a> </p> <a href="https://publications.waset.org/abstracts/160605/screening-of-different-native-genotypes-of-broadleaf-mustard-against-different-diseases" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160605.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">80</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> Screening Psychological Wellness in a South African Banking Industry: Psychometric Properties of the Sense of Coherence-29 Questionnaire and Multifactor Leadership Questionnaire</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisha%20Harry">Nisha Harry</a>, <a href="https://publications.waset.org/abstracts/search?q=Keshia%20Sing"> Keshia Sing</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Orientation: The Multifactor Leadership Questionnaire (MLF) and the sense of coherence-29 (SCS) is an effective tools to assess the prevalence and underlying structures of empirically based taxonomies related to leadership and wellbeing. Research purpose: The purpose of the study was to test the psychometric properties of the SCS and Multifactor Leadership Questionnaire (MLQ) to screen for psychological wellness indices within the banking industry in South Africa. Motivation for the study: The contribution of these two instruments for the purpose of determining psychological wellness in a banking work environment is unique. Research design, approach, or method: The sample consisted of (N = 150) financial staff employed in a South African banking organisation. The age of the sample was: 37% (30 -40 yrs), 31% (20-30 yrs), 26% (40- 50 yrs), and 6% (50+yrs), of which 52% were males, 48% were females. The white race group was the majority at 29%, African at 26%, Coloured at 23%, and Indian was 22%. Main findings: Results from the exploratory factor analysis revealed a two-factor structure as the most satisfactory. Confirmatory factor analyses revealed the two-factor model displayed better good of-fit indices. Practical implications: The factor structure of the Sense of Coherence-29 scale (SCS), and the Multifactor Leadership Questionnaire (MLQ), have a value-added focus to determine psychological wellness within banking staff. It is essential to take into account these constructs when developing employee wellness interventions. Contribution/value add: Understanding the psychometric properties of the SCS, the self-reported form, and the MLQ questionnaire contributes to screening psychological wellness indices such as coping within the banking industry in a developing country like South Africa. Leaders are an important part of the implementation process of organisational employee wellness practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=factorial%20structure" title="factorial structure">factorial structure</a>, <a href="https://publications.waset.org/abstracts/search?q=leadership" title=" leadership"> leadership</a>, <a href="https://publications.waset.org/abstracts/search?q=measurement%20invariance" title=" measurement invariance"> measurement invariance</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20wellness" title=" psychological wellness"> psychological wellness</a>, <a href="https://publications.waset.org/abstracts/search?q=sense%20of%20coherence" title=" sense of coherence"> sense of coherence</a> </p> <a href="https://publications.waset.org/abstracts/159112/screening-psychological-wellness-in-a-south-african-banking-industry-psychometric-properties-of-the-sense-of-coherence-29-questionnaire-and-multifactor-leadership-questionnaire" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159112.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">111</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> The Role of Chennai NGOs in Combatting Human Trafficking </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisha%20James">Nisha James</a>, <a href="https://publications.waset.org/abstracts/search?q=Shubha%20Ranganathan"> Shubha Ranganathan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sex trafficking is a type of human trafficking involving prostitution of individuals for sexual exploitation. The stigma and social isolation they face in the society often makes it difficult for them to become rehabilitated from trafficking, due to which many of them continue in prostitution for years after being sex trafficked. Victims are subjected to violations of their fundamental human rights, deprived of basic medical facilities and undergo long-term abuse. This paper focuses on the role of Non-Governmental Organizations (NGOs) in the rescue and rehabilitation of victims of sex trafficking. Semi-structured interviews were conducted with 26 survivors of sex trafficking, five sex workers and 14 non-community staff members of a project running NGO in the city of Chennai in South India. Chennai has a number of NGOs that are involved in HIV/AIDS awareness and prevention programs. In many cases, rehabilitation of sex trafficking victims is also a mandate of these NGOs. This particular NGO was also involved in development activities towards the eradication of HIV/AIDS. For instance, they were engaged in inculcating safe sex practices among high-risk groups such as sex workers or in fighting for sex worker rights. The study found that the NGO’s role in combatting sex trafficking is overrun by the way it approaches these issue related to HIV/AIDS. Further, their activities are dependent solely on funding. Given that gradually, international funding for HIV/AIDS has slowly been withdrawn, there have been problems such as reduction in the salary of the project staff, the outreach workers and peer educators, many of whom were survivors of sex trafficking who have been able to survive on their wages instead of continuing in prostitution. Therefore, till date, the project funding has helped in making them aware of the health and social consequences of continuing in prostitution, and in supporting them socioeconomically, but the lack of funding may also lead the NGO workers into a state of unemployment, poverty and eventually into being re-trafficked. The study concludes by pointing to the need for disengaging anti-trafficking efforts from the HIV/AIDS related programs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=non-governmental%20organization%20role" title="non-governmental organization role">non-governmental organization role</a>, <a href="https://publications.waset.org/abstracts/search?q=non-governmental%20organization%20staff" title=" non-governmental organization staff"> non-governmental organization staff</a>, <a href="https://publications.waset.org/abstracts/search?q=sex%20trafficking%20survivors" title=" sex trafficking survivors"> sex trafficking survivors</a>, <a href="https://publications.waset.org/abstracts/search?q=sex%20workers" title=" sex workers"> sex workers</a> </p> <a href="https://publications.waset.org/abstracts/22365/the-role-of-chennai-ngos-in-combatting-human-trafficking" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22365.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">301</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> Compensation of Bulk Charge Carriers in Bismuth Based Topological Insulators via Swift Heavy Ion Irradiation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jyoti%20Yadav">Jyoti Yadav</a>, <a href="https://publications.waset.org/abstracts/search?q=Rini%20Singh"> Rini Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Anoop%20%20M.D"> Anoop M.D</a>, <a href="https://publications.waset.org/abstracts/search?q=Nisha%20%20Yadav"> Nisha Yadav</a>, <a href="https://publications.waset.org/abstracts/search?q=N.%20Srinivasa%20Rao"> N.

Defects and strain affect the physical as well as topological insulating properties of the Bi2Te3 thin films by changing their electronic structure. In the present studies, the effect of Ni7+ ion irradiation on the physical and electrical properties of Bi2Te3 thin films was studied. The films were irradiated at five different fluences (5x1011, 1x1012, 3x1012, 5x1012, 1x1013 ions/cm2). Thin films synthesized using the e-beam technique possess a rhombohedral crystal structure with the R-3m space group. The average crystallite size, as determined by x-ray diffraction (XRD) peak broadening, was found to be 18.5 ± 5 (nm). It was also observed that irradiation increases the induced strain. Raman Spectra of the films demonstrate the splitting of A_1u^1 modes originating from the vibrations along the c-axis. This is by the variation in the lattice parameter ‘c,’ as observed through XRD. The atomic force microscopy study indicates the decrease in surface roughness up to the fluence of 3x1012 ions/cm2 and further increasing the fluence increases the roughness. The decrease in roughness may be due to the growth of smaller nano-crystallites on the surface of thin films due to irradiation-induced annealing. X-ray photoelectron spectroscopy studies reveal the composition to be in close agreement to the nominal values i.e. Bi2Te3. The resistivity v/s temperature measurements revealed an increase in resistivity up to the fluence 3x1012 ions/cm2 and a decrease on further increasing the fluence. The variation in electrical resistivity is corroborated with the change in the carrier concentration as studied through low-temperature Hall measurements. A crossover from the n-type to p-type carriers was achieved in the irradiated films. Interestingly, tuning of the Fermi level by compensating the bulk carriers using ion-irradiation could be achieved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Annealing" title="Annealing">Annealing</a>, <a href="https://publications.waset.org/abstracts/search?q=Irradiation" title=" Irradiation"> Irradiation</a>, <a href="https://publications.waset.org/abstracts/search?q=Fermi%20level" title=" Fermi level"> Fermi level</a>, <a href="https://publications.waset.org/abstracts/search?q=Tuning" title=" Tuning"> Tuning</a> </p> <a href="https://publications.waset.org/abstracts/122719/compensation-of-bulk-charge-carriers-in-bismuth-based-topological-insulators-via-swift-heavy-ion-irradiation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122719.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">138</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> Effects of Active Muscle Contraction in a Car Occupant in Whiplash Injury</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisha%20Nandlal%20Sharma">Nisha Nandlal Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Julaluk%20Carmai"> Julaluk Carmai</a>, <a href="https://publications.waset.org/abstracts/search?q=Saiprasit%20Koetniyom"> Saiprasit Koetniyom</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernd%20Markert"> Bernd Markert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Whiplash Injuries are usually associated with car accidents. The sudden forward or backward jerk to head causes neck strain, which is the result of damage to the muscle or tendons. Neck pain and headaches are the two most common symptoms of whiplash. Symptoms of whiplash are commonly reported in studies but the Injury mechanism is poorly understood. Neck muscles are the most important factor to study the neck Injury. This study focuses on the development of finite element (FE) model of human neck muscle to study the whiplash injury mechanism and effect of active muscle contraction on occupant kinematics. A detailed study of Injury mechanism will promote development and evaluation of new safety systems in cars, hence reducing the occurrence of severe injuries to the occupant. In present study, an active human finite element (FE) model with 3D neck muscle model is developed. Neck muscle was modeled with a combination of solid tetrahedral elements and 1D beam elements. Muscle active properties were represented by beam elements whereas, passive properties by solid tetrahedral elements. To generate muscular force according to inputted activation levels, Hill-type muscle model was applied to beam elements. To simulate non-linear passive properties of muscle, solid elements were modeled with rubber/foam material model. Material properties were assigned from published experimental tests. Some important muscles were then inserted into THUMS (Total Human Model for Safety) 50th percentile male pedestrian model. To reduce the simulation time required, THUMS lower body parts were not included. Posterior to muscle insertion, THUMS was given a boundary conditions similar to experimental tests. The model was exposed to 4g and 7g rear impacts as these load impacts are close to low speed impacts causing whiplash. The effect of muscle activation level on occupant kinematics during whiplash was analyzed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20model" title="finite element model">finite element model</a>, <a href="https://publications.waset.org/abstracts/search?q=muscle%20activation" title=" muscle activation"> muscle activation</a>, <a href="https://publications.waset.org/abstracts/search?q=neck%20muscle" title=" neck muscle"> neck muscle</a>, <a href="https://publications.waset.org/abstracts/search?q=whiplash%20injury%20prevention" title=" whiplash injury prevention"> whiplash injury prevention</a> </p> <a href="https://publications.waset.org/abstracts/42971/effects-of-active-muscle-contraction-in-a-car-occupant-in-whiplash-injury" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42971.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">357</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Clostridium thermocellum DBT-IOC-C19, A Potential CBP Isolate for Ethanol Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisha%20Singh">Nisha Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Munish%20Puri"> Munish Puri</a>, <a href="https://publications.waset.org/abstracts/search?q=Collin%20Barrow"> Collin Barrow</a>, <a href="https://publications.waset.org/abstracts/search?q=Deepak%20Tuli"> Deepak Tuli</a>, <a href="https://publications.waset.org/abstracts/search?q=Anshu%20S.%20Mathur"> Anshu S. Mathur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The biological conversion of lignocellulosic biomass to ethanol is a promising strategy to solve the present global crisis of exhausting fossil fuels. The existing bioethanol production technologies have cost constraints due to the involvement of mandate pretreatment and extensive enzyme production steps. A unique process configuration known as consolidated bioprocessing (CBP) is believed to be a potential cost-effective process due to its efficient integration of enzyme production, saccharification, and fermentation into one step. Due to several favorable reasons like single step conversion, no need of adding exogenous enzymes and facilitated product recovery, CBP has gained the attention of researchers worldwide. However, there are several technical and economic barriers which need to be overcome for making consolidated bioprocessing a commercially viable process. Finding a natural candidate CBP organism is critically important and thermophilic anaerobes are preferred microorganisms. The thermophilic anaerobes that can represent CBP mainly belong to genus Clostridium, Caldicellulosiruptor, Thermoanaerobacter, Thermoanaero bacterium, and Geobacillus etc. Amongst them, Clostridium thermocellum has received increased attention as a high utility CBP candidate due to its highest growth rate on crystalline cellulose, the presence of highly efficient cellulosome system and ability to produce ethanol directly from cellulose. Recently with the availability of genetic and molecular tools aiding the metabolic engineering of Clostridium thermocellum have further facilitated the viability of commercial CBP process. With this view, we have specifically screened cellulolytic and xylanolytic thermophilic anaerobic ethanol producing bacteria, from unexplored hot spring/s in India. One of the isolates is a potential CBP organism identified as a new strain of Clostridium thermocellum. This strain has shown superior avicel and xylan degradation under unoptimized conditions compared to reported wild type strains of Clostridium thermocellum and produced more than 50 mM ethanol in 72 hours from 1 % avicel at 60°C. Besides, this strain shows good ethanol tolerance and growth on both hexose and pentose sugars. Hence, with further optimization this new strain could be developed as a potential CBP microbe. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Clostridium%20thermocellum" title="Clostridium thermocellum">Clostridium thermocellum</a>, <a href="https://publications.waset.org/abstracts/search?q=consolidated%20bioprocessing" title=" consolidated bioprocessing"> consolidated bioprocessing</a>, <a href="https://publications.waset.org/abstracts/search?q=ethanol" title=" ethanol"> ethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=thermophilic%20anaerobes" title=" thermophilic anaerobes"> thermophilic anaerobes</a> </p> <a href="https://publications.waset.org/abstracts/33981/clostridium-thermocellum-dbt-ioc-c19-a-potential-cbp-isolate-for-ethanol-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33981.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">400</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> Assesment of Genetic Fidelity of Micro-Clones of an Aromatic Medicinal Plant Murraya koenigii (L.)

Spreng locally known as “Curry patta” or “Meetha neem” belonging to the family Rutaceae that grows wildly in Southern Asia. Its aromatic leaves are commonly used as the raw material for traditional medicinal formulations in India. The leaves contain essential oil and also used as a condiment. Several monomeric and binary carbazol alkaloids present in the various plant parts. These alkaloids have been reported to possess anti-microbial, mosquitocidal, topo-isomerase inhibition and antioxidant properties. Some of the alkaloids reported in this plant have showed anti carcinogenic and anti-diabetic properties. The conventional method of propagation of this tree is limited to seeds only, which retain their viability for only a short period. Hence, a biotechnological approach might have an advantage edging over traditional breeding as well as the genetic improvement of M. koenigii within a short period. The development of a reproducible regeneration protocol is the prerequisite for ex situ conservation and micropropagation. An efficient protocol for high frequency regeneration of in vitro plants of Murraya koenigii via different explants such as- nodal segments, intermodal segments, leaf, root segments, hypocotyle, cotyledons and cotyledonary node explants is described. In the present investigation, assessment of clonal fidelity in the micropropagated plantlets of Murraya koenigii was attempted using RAPD and ISSR markers at different pathways of plant tissue culture technique. About 20 ISSR and 40 RAPD primers were used for all the samples. Genomic DNA was extracted by CTAB method. ISSR primer were found to be more suitable as compared to RAPD for the analysis of clonal fidelity of M. koenigii. The amplifications however, were finally performed using RAPD, ISSR markers owing to their better performance in terms of generation of amplification products. In RAPD primer maximum 75% polymorphism was recorded in OPU-2 series which exhibited out of 04 scorable bands, three bands were polymorphic with a band range of size 600-1500 bp. In ISSR primers the UBC 857 showed 50% polymorphism with 02 band were polymorphic of band range size between 400-1000 bp. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genetic%20fidelity" title="genetic fidelity">genetic fidelity</a>, <a href="https://publications.waset.org/abstracts/search?q=Murraya%20koenigii" title=" Murraya koenigii"> Murraya koenigii</a>, <a href="https://publications.waset.org/abstracts/search?q=aromatic%20plants" title=" aromatic plants"> aromatic plants</a>, <a href="https://publications.waset.org/abstracts/search?q=ISSR%20primers" title=" ISSR primers "> ISSR primers </a> </p> <a href="https://publications.waset.org/abstracts/20710/assesment-of-genetic-fidelity-of-micro-clones-of-an-aromatic-medicinal-plant-murraya-koenigii-l-spreng" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20710.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">501</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> Kinetic Modelling of Fermented Probiotic Beverage from Enzymatically Extracted Annona Muricata Fruit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Calister%20Wingang%20Makebe">Calister Wingang Makebe</a>, <a href="https://publications.waset.org/abstracts/search?q=Wilson%20%20Ambindei%20Agwanande"> Wilson Ambindei Agwanande</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Jong%20Nso"> Emmanuel Jong Nso</a>, <a href="https://publications.waset.org/abstracts/search?q=P.%20Nisha"> P.

It aimed at a better understanding of the traditional process as an initial step for future optimization. Annona muricata L. juice was fermented with L. acidophilus (NCDC 291) (LA), L. casei (NCDC 17) (LC), and a blend of LA and LC (LCA) for 72 h at 37 °C. Experimental data were fitted into mathematical models (Monod, Logistic and Luedeking and Piret models) using MATLAB software, to describe biomass growth, sugar utilization, and organic acid production. The optimal fermentation time was obtained based on cell viability, which was 24 h for LC and 36 h for LA and LCA. The model was particularly effective in estimating biomass growth, reducing sugar consumption, and lactic acid production. The values of the determination coefficient, R2, were 0.9946, 0.9913 and 0.9946, while the residual sum of square error, SSE, was 0.2876, 0.1738 and 0.1589 for LC, LA and LCA, respectively. The growth kinetic parameters included the maximum specific growth rate, µm, which was 0.2876 h-1, 0.1738 h-1 and 0.1589 h-1 as well as the substrate saturation, Ks, with 9.0680 g/L, 9.9337 g/L and 9.0709 g/L respectively for LC, LA and LCA. For the stoichiometric parameters, the yield of biomass based on utilized substrate (YXS) was 50.7932, 3.3940 and 61.0202, and the yield of product based on utilized substrate (YPS) was 2.4524, 0.2307 and 0.7415 for LC, LA, and LCA, respectively. In addition, the maintenance energy parameter (ms) was 0.0128, 0.0001 and 0.0004 with respect to LC, LA and LCA. With the kinetic model proposed by Luedeking and Piret for lactic acid production rate, the growth associated, and non-growth associated coefficients were determined as 1.0028 and 0.0109, respectively. The model was demonstrated for batch growth of LA, LC, and LCA in Annona muricata L. juice. The present investigation validates the potential of Annona muricata L. based medium for heightened economical production of a probiotic medium. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20acidophilus" title="L. acidophilus">L. acidophilus</a>, <a href="https://publications.waset.org/abstracts/search?q=L.%20casei" title=" L. casei"> L. casei</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation" title=" fermentation"> fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetics" title=" kinetics"> kinetics</a> </p> <a href="https://publications.waset.org/abstracts/177100/kinetic-modelling-of-fermented-probiotic-beverage-from-enzymatically-extracted-annona-muricata-fruit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177100.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">82</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> Modeling of the Fermentation Process of Enzymatically Extracted Annona muricata L.
