its rulers and nation. In his reign, he convinced the rulers toward Islamic way of life and succeed in his goal. After his death in 1624, his family consecutively produced prominent scholars to present. Some of them moved to Afghanistan and Pakistan's cities i.e., Jalalabad, Qandhar, Peshawar, Queta, Shikarpur, Hyderabad, and Sehwan. They played a vital role in their areas and transmitted spiritual and legal Islamic teachings to people. This research is aimed to elaborate efforts of the family's Sindh settled branch from 1898-present in fields of politics and Islamic education. Their link with Shaikh Ahmad Sirhindi will be provided in the introduction. After that, the work will explain their scholarly published work briefly in different fields of Islamic studies such as Quran exegeses and its translation in Sindhi language, Hadith and its sciences, Islamic Jurisprudence, Sufism and etc. In addition, their political role will be briefly discussed in the research throughout the period, especially their noticeable role in the separate homeland for Muslims in the subcontinent. Furthermore, the impact of their scholarly work, political influence and spirituality will be enlightened. Lastly, the research will present the critical viewpoint on their struggle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shaikh%20Ahmad%20Sirhindi" title="Shaikh Ahmad Sirhindi">Shaikh Ahmad Sirhindi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sirhindi%20scholars" title=" Sirhindi scholars"> Sirhindi scholars</a>, <a href="https://publications.waset.org/abstracts/search?q=Sindh" title=" Sindh"> Sindh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sufism" title=" Sufism"> Sufism</a> </p> <a href="https://publications.waset.org/abstracts/89518/sirhindi-familys-islamic-movements-in-sindh-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89518.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">251</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1071</span> Fabrication of Graphene Oxide Based Planar Hetero-Junction Perovskite Solar Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khursheed%20Ahmad">Khursheed Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Shaikh%20M.%20Mobin"> Shaikh M.

The PSCs was fabricated under air using GO/PEDOT:PSS as hole transport layer while the carbon tape used as a back contact to complete the device. The fabricated PSCs device exhibited good stability and performance in terms of power conversion efficiency of 5.2%. The PSCs devices were exposed to ambient condition for 4 days which shows excellent stability confirmed by XRD analysis. We believed that the stability of the planar heterojunction perovskite solar cell may be due the presence of GO which inhibits the direct contact between PEDOT:PSS and MAPbI3. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=graphene%20oxide" title="graphene oxide">graphene oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=perovskite%20solar%20cells" title=" perovskite solar cells"> perovskite solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=hole%20transport%20layer" title=" hole transport layer"> hole transport layer</a>, <a href="https://publications.waset.org/abstracts/search?q=PEDOT%3APSS" title=" PEDOT:PSS"> PEDOT:PSS</a> </p> <a href="https://publications.waset.org/abstracts/84068/fabrication-of-graphene-oxide-based-planar-hetero-junction-perovskite-solar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84068.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">181</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1070</span> Jalal-Ale-Ahmad and ‘Critical Consciousness’: A Comparative Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zohreh%20Ramin">Zohreh Ramin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the most important contributions that Edward Said has had in the realm of critical theory is his insistence on the worldliness of the text and the critic. By this, Said meant that the critic and the text must be considered in their ‘material’ contexts. Foregrounding the substantial role of a critic as embodying what he refers to as ‘critical consciousness’, a true critic, Said maintains, is one who can stand between the ‘dominant culture’ and ‘the totalizing forms of critical systems.’ Considered as one of Iran’s major contemporary intellectuals, Jalal Ale Ahmad is responsible for introducing the idea of ‘Westoxication’ in Iran, constructing a social paradigm of the necessity to return to tradition in contemporary Iran. The present paper intends to study Al-Ahmad’s definition of the orient versus the occident, his criticism of the ‘machination’ of contemporary Iranian society, and his solution to the problem of ‘Westoxication’. The objective of this study is to see whether Ale Ahmad can be considered as embodying the spirit of ‘critical consciousness’ as described by Said as the necessary tool in the hands of an intellectual who is simultaneously attached filitavely to his culture but can detach himself affilitavely through employing critical consciousness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Westoxication" title="Westoxication">Westoxication</a>, <a href="https://publications.waset.org/abstracts/search?q=filiative" title=" filiative"> filiative</a>, <a href="https://publications.waset.org/abstracts/search?q=affiliative" title=" affiliative"> affiliative</a>, <a href="https://publications.waset.org/abstracts/search?q=machination" title=" machination"> machination</a> </p> <a href="https://publications.waset.org/abstracts/137668/jalal-ale-ahmad-and-critical-consciousness-a-comparative-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137668.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">184</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">1069</span> Angiotensin Converting Enzyme (ACE) and Angiotensinogen (AGT) Gene Variants in Pakistani Patients of Diabetes Mellitus and Diabetic Nephropathy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rozeena%20Shaikh">Rozeena Shaikh</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20M%20Shahid"> Syed M Shahid</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamil%20Ahmad"> Jamil Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Qaisar%20Mansoor"> Qaisar Mansoor</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ismail"> Muhammad Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Abid%20Azhar"> Abid Azhar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Diabetes mellitus (DM) is a prevalent non-communicable disease worldwide. In most high-income countries as well as middle-income and low- income countries. DM is among the top causes of deaths. DM may lead to many vascular complications like hypertension, nephropathy, retinopathy, neuropathy, and foot. Diabetic nephropathy (DN) characterized by persistent albuminuria is a leading cause of end stage renal failure (ESRF). Pathogenesis of diabetic nephropathy is implicated by the polymorphisms in genes encoding the components of reninangiotensin- aldosteron system (RAAS) which include angiotensinogen (AGT), angiotensin-II receptor and particularly angiotensin converting enzyme (ACE) gene. Method: Study subjects include 110 control, 110 patients with DM without hypertension, 110 patients with DM with hypertension and 110 patients with DN. Blood samples were collected for Biochemical analysis and PCR and sequencing for the specific region of both genes. Results: The frequency of DD genotype and D allele of ACE (I/D) was significantly (p<0.05) high in DM normotensive, DM hypertensive and DN patients when compared to control. The ACE G2350A genotypes and allele frequencies were significantly different (p<0.05) in DM hypertensive patients as compared to control and DN, while no difference was observed between DM normotensive and DN when compared to control. The genotypes and alleles of AGT (M268T) polymorphism were significantly different (p<0.05) in DM normotensive, DM hypertensive and DN when compared to control. Conclusion: The DD genotype and D allele of ACE (I/D), GG genotype and G allele of ACE (G2350A) and the TT genotype and T allele of AGT (M268T) polymorphism have shown a significant difference in genotype and allele frequencies between controls and patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genetic%20variations" title="genetic variations">genetic variations</a>, <a href="https://publications.waset.org/abstracts/search?q=ACE" title=" ACE"> ACE</a>, <a href="https://publications.waset.org/abstracts/search?q=AGT" title=" AGT"> AGT</a>, <a href="https://publications.waset.org/abstracts/search?q=diabetes%20mellitus" title=" diabetes mellitus"> diabetes mellitus</a>, <a href="https://publications.waset.org/abstracts/search?q=diabetic%20nephropathy" title=" diabetic nephropathy"> diabetic nephropathy</a>, <a href="https://publications.waset.org/abstracts/search?q=Pakistan" title=" Pakistan"> Pakistan</a> </p> <a href="https://publications.waset.org/abstracts/15166/angiotensin-converting-enzyme-ace-and-angiotensinogen-agt-gene-variants-in-pakistani-patients-of-diabetes-mellitus-and-diabetic-nephropathy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15166.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">392</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">1068</span> A Study of the Formation, Existence and Stability of Localised Pulses in PDE</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayaz%20Ahmad">Ayaz Ahmad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> TOPIC: A study of the formation ,existness and stability of localised pulses in pde Ayaz Ahmad ,NITP, Abstract:In this paper we try to govern the evolution deterministic variable over space and time .We analysis the behaviour of the model which allows us to predict and understand the possible behaviour of the physical system .Bifurcation theory provides a basis to systematically investigate the models for invariant sets .Exploring the behaviour of PDE using bifurcation theory which provides many challenges both numerically and analytically.

Advanced and sophisticated techniques were used to confirm the synthesis, size, and shape of these NPs. Rounded, clustered NPs of size 5.343 nm were formed. Both the plain and core shell NPs were tested against MDR bacteria (E. cloacae, E. amnigenus, Shigella, S. odorifacae, Citrobacter, and E. coli). Both of the NPs showed excellent antibacterial properties, whereas E. cloacae showed maximum zone of inhibition of 16 mm, 27 mm, and 32 mm for 500 μg/ml, 1000 μg/ml, and 1500 μg/ml, respectively for plain ZnO NPs and 18 mm, 28 mm and 35 mm for 500 μg/ml, 1000 μg/ml and 1500 μg/ml for core shell NPs. These NPs were also biocompatible on human red blood cells showing little hemolysis of only 4% for 70 μg/ml for plain NPs and 1.5% for 70 μg/ml for core shell NPs. Core shell NPs were highly biocompatible because of the PEG. Their therapeutic effect as photosensitizers in photodynamic therapy (PDT) for cancer treatment was also monitored. The cytotoxicity of ZnO and PEG-ZnO was evaluated using MTT assay. Our results demonstrated that these NPs could generate ROS inside tumor cells after irradiation which in turn initiates an apoptotic pathway leading to cell death hence proving to be an effective candidate for PDT. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ZnO" title="ZnO">ZnO</a>, <a href="https://publications.waset.org/abstracts/search?q=hemolysis" title=" hemolysis"> hemolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=cytotoxiciy%20assay" title=" cytotoxiciy assay"> cytotoxiciy assay</a>, <a href="https://publications.waset.org/abstracts/search?q=photodynamic%20therapy" title=" photodynamic therapy"> photodynamic therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=antibacterial" title=" antibacterial"> antibacterial</a> </p> <a href="https://publications.waset.org/abstracts/153973/controlled-size-synthesis-of-zno-and-peg-zno-nps-and-their-biological-evaluation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153973.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">140</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">1064</span> Characteristics of Nanosilica-Geopolymer Nanocomposites and Mixing Effect</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Assaedi">H.

The harmonic and ripple contents of the output DC voltage supplied by high voltage DC circuits require the use of costly capacitors to smooth the output voltage after rectification. This paper proposes a new modular multiplier high voltage DC generator with embedded Cockcroft-Walton circuits that achieve a negligible harmonic and ripple contents of the output DC voltage without the need for costly filters to produce a nearly constant output voltage. In this new topology, Cockcroft-Walton modules are connected in series to produce a high DC output voltage. The modules are supplied by low input AC voltage sources that have the same magnitude and frequency and shifted from each other by a certain angle to eliminate the harmonics from the output voltage. The small ripple factor is provided by the smoothing column capacitors and the phase shifted input voltages of the cascaded modules. The constituent harmonics within each module are determined using Fourier analysis. The viability of the proposed DC generator for testing purposes and the effectiveness of the cascaded connection are confirmed by numerical simulations using MATLAB/Simulink. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cockcroft-Walton%20circuit" title="Cockcroft-Walton circuit">Cockcroft-Walton circuit</a>, <a href="https://publications.waset.org/abstracts/search?q=harmonics" title=" harmonics"> harmonics</a>, <a href="https://publications.waset.org/abstracts/search?q=ripple%20factor" title=" ripple factor"> ripple factor</a>, <a href="https://publications.waset.org/abstracts/search?q=HVDC%20generator" title=" HVDC generator"> HVDC generator</a> </p> <a href="https://publications.waset.org/abstracts/93486/modular-harmonic-cancellation-in-a-multiplier-high-voltage-direct-current-generator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93486.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">367</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">1060</span> Assessment of Solid Insulating Material Using Partial Discharge Characteristics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qasim%20Khan">Qasim Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Furkan%20Ahmad"> Furkan Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Asfar%20A.%20Khan"> Asfar A.

In this paper, a new three-time level implicit approach based on cubic trigonometric B-spline for the approximate solution of wave equation is developed. The usual finite difference approach is used to discretize the time derivative while cubic trigonometric B-spline is applied as an interpolating function in the space dimension. Von Neumann stability analysis is used to analyze the proposed method. Two problems are discussed to exhibit the feasibility and capability of the method. The absolute errors and maximum error are computed to assess the performance of the proposed method.

Among biotic factors, Phytoplasma infection induces abnormality influencing the physiology as well as morphology of plants. In 16Sr-IX group phytoplasma-infected brassica compestris, flower abnormalities have been associated with changes in the expression of floral development genes. To determine whether methylation was involved in down-regulation of flower development, the process of DNA methylation and Demethylation was investigated as a possible mechanism for regulation of floral gene expression in phytoplasma infected Brassica transmitted by Orosious orientalis vector by using RT-PCR, MSRE-PCR, Southern blotting, Bisulfite Sequencing, etc. Transcriptional expression of methylated genes was found to be globally down-regulated in plants infected with phytoplasma, but not severely in those infested by insect vectors and variation in expression was found in genes involved in methylation. These results also showed that genes particularly orthologous to Arabidopsis APETALA3 involved in petal formation and flower development was down-regulated severely in phytoplasma-infected brassica and with the fact that phytoplasma and insect induce variation in developmental gene expression. The DNA methylation status of flower developmental gene in phytoplasma infected plants with 5-azacytidine restored gene expression strongly suggesting that DNA methylation was involved in down-regulation of floral development genes in phytoplasma infected brassica. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genes%20expression" title="genes expression">genes expression</a>, <a href="https://publications.waset.org/abstracts/search?q=phytoplasma" title=" phytoplasma"> phytoplasma</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20methylation" title=" DNA methylation"> DNA methylation</a>, <a href="https://publications.waset.org/abstracts/search?q=flower%20development" title=" flower development"> flower development</a> </p> <a href="https://publications.waset.org/abstracts/87401/study-on-developmental-and-pathogenesis-related-genes-expression-deregulation-in-brassica-compestris-infected-with-16sr-ix-associated-phytoplasma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87401.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">374</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">1052</span> Effect of Bull Exposure on Post-Partum Estrus Interval in Nili-Ravi Buffaloes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Saleem%20Akhtar">Muhammad Saleem Akhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mushtaq%20Hussain%20Lashari"> Mushtaq Hussain Lashari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ejaz%20Ahmad"> Ejaz Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Tanveer%20Ahmad"> Tanveer Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Laeeq%20Akbar%20Lodhi"> Laeeq Akbar Lodhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ijaz%20Ahmad"> Ijaz Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Masood%20Akhtar"> Masood Akhtar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study was to determine the effect of bull exposure continuously or intermittently or its excretory products after calving on postpartum interval to estrus, in Nili-Ravi buffalo. Forty-eight buffaloes of Nili-Ravi breed were allocated one of the four treatments in a totally randomized plan using a 4 x 1 factorial design. The four treatment groups were BEC (Bull Exposed Continuously), BEI (Bull Exposed Intermittently), EPB (Excretory Products of Bull) and BNE (Bull Not Exposed). BEC; buffaloes (n = 12) were exposed continuously to the physical presence of a bull whereas in BEI; buffaloes (n = 12) were exposed intermittently to the physical presence of bull. EPB; buffaloes (n = 12) were exposed to discharge waste (urine and feces) of bull and BNE buffaloes (n = 12) were not exposed to a bull or discharge waste of bulls. Buffaloes were exposed on day 15 after parturition. Day 15 postpartum represented d 0 for each treatment. The postpartum interval from calving to first behavioural estrus was 66.88 days in BEC, 75.12 days in BEI, 77.28 days in EPB and 76.5 days in BNE treatments. Postpartum interval to first behavioural estrus was shorter in BEC than BEI, EPB, and BNE treatments. There was no significant difference in postpartum interval to estrus between BEI, EPB and BNE treatments. In present study, the percentage of buffaloes showing estrus during experimental period was 75.0%, 66.66%, 66.66% and 58.33% in BEC, BEI, EPB and BNE treatments, respectively. The mean serum progesterone concentration did not differ significantly between BEC and other (BEI, EPB, and BNE) treatments. It was concluded that presence of bull has positive effect in reducing calving interval in Nili Ravi buffalo. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calving%20interval" title="calving interval">calving interval</a>, <a href="https://publications.waset.org/abstracts/search?q=biostimulation" title=" biostimulation"> biostimulation</a>, <a href="https://publications.waset.org/abstracts/search?q=buffalo" title=" buffalo"> buffalo</a>, <a href="https://publications.waset.org/abstracts/search?q=bull%20exposure" title=" bull exposure"> bull exposure</a> </p> <a href="https://publications.waset.org/abstracts/100620/effect-of-bull-exposure-on-post-partum-estrus-interval-in-nili-ravi-buffaloes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100620.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">255</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">1051</span> Grounded Theory of Consumer Loyalty: A Perspective through Video Game Addiction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bassam%20Shaikh">Bassam Shaikh</a>, <a href="https://publications.waset.org/abstracts/search?q=R.%20S.%20A.%20Jumain"> R.

The writing of fables, in prose and verse, was widely cultivated not only in pre-Islamic Arabia but also in the middle ages, reaching its culmination with the Egyptian poet and man of letters Ahmad Shawqī (1989-1932), who revived the ancient tradition, a relatively minor and unexploited genre in the modern era, and re-wrote rimed fables with an Arab Islamic flavor, articulating a set of modern ethico-political concepts and sensibilities such as a belief in good judgment in governance, individual liberty, democracy, a sense of the brotherhood of man and justice. This essay aims to restore the 20th Century poet to his rightful place in the international pantheon of literary achievement, and offers an examination of the Arabian fabulist tradition as it appears in Arabic literature, and a treatment of this genre re-visiting a few representative samples of Ahmad Shawqī collection of fables and their implications for contemporary politics in the Middle East. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fable" title="fable">fable</a>, <a href="https://publications.waset.org/abstracts/search?q=politcs" title=" politcs"> politcs</a>, <a href="https://publications.waset.org/abstracts/search?q=governace" title=" governace"> governace</a>, <a href="https://publications.waset.org/abstracts/search?q=democracy" title=" democracy"> democracy</a>, <a href="https://publications.waset.org/abstracts/search?q=ethics%20of%20care" title=" ethics of care "> ethics of care </a> </p> <a href="https://publications.waset.org/abstracts/28913/arabic-fables-in-contemporary-garbs-ahmed-shawqis-reconstruction-of-fables-in-the-modern-era" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28913.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">676</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">1047</span> Supersized Pricing and Anticipated Consumption Guilt: The Moderating Role of Product Type and Health Claims</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asim%20Shabir">Asim Shabir</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruqia%20Shaikh"> Ruqia Shaikh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Supersized pricing is an effective strategy often used by marketers to make consumers buy more. However, such a strategy also results in more purchases and consumption, especially of hedonic food products. This study brings interesting insights about supersized pricing as it provides value-based justification to consumers; as a result, the guilt associated with the purchase and consumption of hedonic products diminishes, which mediates the impact between supersized pricing and size choice. Interestingly, there is a three-way interaction between pricing, product type, and health goal prime. Health prime diminishes the impact of supersized pricing in the case of more hedonic products (unhealthy) compared to less hedonic (perceived as healthy) products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=supersized%20pricing" title="supersized pricing">supersized pricing</a>, <a href="https://publications.waset.org/abstracts/search?q=anticipated%20consumption%20guilt" title=" anticipated consumption guilt"> anticipated consumption guilt</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20claim" title=" health claim"> health claim</a>, <a href="https://publications.waset.org/abstracts/search?q=product%20type" title=" product type"> product type</a> </p> <a href="https://publications.waset.org/abstracts/169085/supersized-pricing-and-anticipated-consumption-guilt-the-moderating-role-of-product-type-and-health-claims" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169085.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">108</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">1046</span> Social Media and Student-Teacher Relationship: A Case Study Form Kashmir University</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wahid%20Ahmad%20Dar">Wahid Ahmad Dar</a>, <a href="https://publications.waset.org/abstracts/search?q=Irshad%20Ahmad%20Najar"> Irshad Ahmad Najar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The influence of social media is percolating to every corner of our social life.

Differences have been found in student’s ability to draw benefits from using ICT. Besides digital divides in access and usage, there are attitudinal differences among students towards ICT aligned with traditional forms of social differences. The paper particularly focusses on how students from diverse backgrounds are using social media to interact with their teachers and how such interactions differ on the basis of social class, gender and residential background of students. A qualitative research methodology has been used for answering these questions. Open-ended questionnaire has been designed and administered to a sample of postgraduate students from University of Kashmir drawn purposively ensuring optimum number of subjects from all backgrounds.

The devices also demonstrated a maximum modulation bandwidth (<em>f</em><sub>-3dB max</sub>) of more than 16 GHz at a bias current less than the industrial bias current standard for reliability by 25%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=current%20density" title="current density">current density</a>, <a href="https://publications.waset.org/abstracts/search?q=high-speed%20VCSELs" title=" high-speed VCSELs"> high-speed VCSELs</a>, <a href="https://publications.waset.org/abstracts/search?q=modulation%20bandwidth" title=" modulation bandwidth"> modulation bandwidth</a>, <a href="https://publications.waset.org/abstracts/search?q=small-signal%20characteristics" title=" small-signal characteristics"> small-signal characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20impedance" title=" thermal impedance"> thermal impedance</a>, <a href="https://publications.waset.org/abstracts/search?q=vertical-cavity%20surface-emitting%20lasers" title=" vertical-cavity surface-emitting lasers"> vertical-cavity surface-emitting lasers</a> </p> <a href="https://publications.waset.org/abstracts/78212/improved-small-signal-characteristics-of-infrared-850-nm-top-emitting-vertical-cavity-lasers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78212.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">570</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">1043</span> Challenges and Opportunities of Cloud-Based E-Learning Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kashif%20Laeeq">Kashif Laeeq</a>, <a href="https://publications.waset.org/abstracts/search?q=Zubair%20A.%20Shaikh"> Zubair A.

Due to ease of learning with various other benefits, several educational institutions are adopting the e-learning models. Some institutions are still willing to transform their educational system on to e-learning, but due to limited resources, they are still compromising on the old traditional system. The cloud computing could be one of the best solutions to overcome this problem by providing hardware, software, and infrastructure resources with cost efficient manner. The adoption of cloud computing in education will bring revolution in this paradigm. This paper introduces various positive features of e-learning and presents a way how cloud computing technology can be provisioned e-learning model. This paper also investigates the numerous challenges and opportunities that would be observed in cloud computing adoption in e-learning domain. The concept and knowledge present in this paper may create a new direction of research in the domain of cloud-based e-learning. <p class="card-text"><strong>Keywords:</strong> <a
