There are listed 43 genera for Colombia but without a specific number of their species. No species of the genus Agriotes Eschscholtz (Elaterinae: Agriotini) have been recorded in Colombia. Currently, the subtribe Agriotina in the New World includes three genera: Agriotes, Bohartina Arias and Dalopius Eschscholtz. Historically, the genera Agriotes and Dalopius have had significant taxonomic problems due to their morphological resemblance. These similarities motivated several specialists to generate taxonomic movements such as synonyms and segregations of species in these genera on several occasions. To trying to solve these taxonomic problems, an author proposes some morphological characters present in the larvae, but mainly some genital characters of the females, such as the sclerotized plates of the bursa copulatrix. After examining material newly collected in Colombia, we found a click beetle having a unique combination of diagnostic characters that clearly separate it from any other genera of Agriotina. Hence, we describe and illustrate this click beetle under the name Raphaellus deusminutosi Zurita-García, Morales-Perdomo & Martínez-Luque n. gen. & n. sp., and we also compare this genus with the other New World genera of the subtribes Agriotina. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=click%20beetles" title="click beetles">click beetles</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20genus" title=" new genus"> new genus</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20species" title=" new species"> new species</a>, <a href="https://publications.waset.org/abstracts/search?q=elaterinae" title=" elaterinae"> elaterinae</a>, <a href="https://publications.waset.org/abstracts/search?q=raphaellus%20deusminutosi" title=" raphaellus deusminutosi"> raphaellus deusminutosi</a> </p> <a href="https://publications.waset.org/abstracts/175772/a-new-genus-and-species-of-agriotina-laporte-1840-coleoptera-elateridae-agriotini-from-colombia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175772.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">84</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">98</span> Seasons and Saproxylic Beetles Biodiversity in an Urban Park in Tunisia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zina%20Nasr">Zina Nasr</a>, <a href="https://publications.waset.org/abstracts/search?q=Faiek%20Errouissi"> Faiek Errouissi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Forest ecosystems are known for its ability to contain a large diversity of fauna especially insects that represent a huge taxonomic group. A portion of forest insects are recognized as saproxylic including the group of organisms that ‘depend on dead or dying wood’ about them, 20% are beetles. We focused our study on saproxylic beetles in an old urban park ‘the park of Belvedere’, located in the north west of Tunis (36° 49'21’ N 10°10'24’ W). The vegetation is dominated by old trees (Eucalyptus, Olea, Aberia, Pinus) and many fallen wood exist. Saproxylic beetles were collected using three interception traps set in the park over one year (from June 2014 to May 2015) and recovered monthly. In total, we collected 189 beetles belonging to 20 families and 57 species. Several saproxylic families (Bostrichidae, Cerambycidae, Curculionidae, Melyridae, Nitidulidae, Staphylinidae), and well known genus (Rhizopertha, Thrychoplerus, Otiorhychus, Dolichosoma, Epuraea, Anotylus) are recorded. We have retained the largest activity of beetles in spring and a very low richness in winter with zero insect per traps. This result was certainly caused by the variation of meteorological factors that mainly influenced the activity of these organisms. Therefore, we were interested on the saproxylic diversity in an urban ‘forest’, and these results will be more interesting when they are compared in the future with other works from natural forest. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=saproxylic%20beetles" title="saproxylic beetles">saproxylic beetles</a>, <a href="https://publications.waset.org/abstracts/search?q=seasons" title=" seasons"> seasons</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20park" title=" urban park"> urban park</a>, <a href="https://publications.waset.org/abstracts/search?q=wood" title=" wood"> wood</a> </p> <a href="https://publications.waset.org/abstracts/67561/seasons-and-saproxylic-beetles-biodiversity-in-an-urban-park-in-tunisia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67561.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">344</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">97</span> Using Neural Networks for Click Prediction of Sponsored Search</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Afroze%20Ibrahim%20Baqapuri">Afroze Ibrahim Baqapuri</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilya%20Trofimov"> Ilya Trofimov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sponsored search is a multi-billion dollar industry and makes up a major source of revenue for search engines (SE). Click-through-rate (CTR) estimation plays a crucial role for ads selection, and greatly affects the SE revenue, advertiser traffic and user experience. We propose a novel architecture of solving CTR prediction problem by combining artificial neural networks (ANN) with decision trees. First, we compare ANN with respect to other popular machine learning models being used for this task. Then we go on to combine ANN with MatrixNet (proprietary implementation of boosted trees) and evaluate the performance of the system as a whole.

In the first phase of the present study, an intensive investigation of this group following the gathering of all the bibliographic, museological data and based on a recent collection of 17020 specimens in 106 localities in Tunisia, allowed to confirm with certainty the presence of 94 species distributed in 43 genera, 4 families and 3 sub-families. Only 81 species distributed in 38 genres, 4 families, and 3 sub-families, have been found during our prospections. The population of dung beetles Scarabaeides is composed of 58% of Aphodiidae, 39.51% of Scarabaeidae, and 8.64% of Geotrupidae. Biogeographic affinities of the species were determined and showed that 42% of the identified species have a wide Palaearctic distribution, the endemism is very low, only 3 species are endemic to Tunisia Mecynodes demoflysi, Neobodilus marani, and Thorectes demoflysi, 29 species have a wide distribution, 35 are northern and 17 are southern species. Moreover, others are dependent on very specific Biotopes like Sisyphus schaefferi linked to the northwest of Tunisia and Scarabaeus semipunctatus related to the coastal area north of Tunisia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dung%20beetles" title="dung beetles">dung beetles</a>, <a href="https://publications.waset.org/abstracts/search?q=Tunisia" title=" Tunisia"> Tunisia</a>, <a href="https://publications.waset.org/abstracts/search?q=composition" title=" composition"> composition</a>, <a href="https://publications.waset.org/abstracts/search?q=biogeography" title=" biogeography"> biogeography</a> </p> <a href="https://publications.waset.org/abstracts/87008/tunisian-dung-beetles-fauna-composition-and-biogeographic-affinities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87008.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">249</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">95</span> Evaluation of Pheromone and Tree Trap Efficiency in Orthotomicus erosus (Col: Curculionidae: Scolytinae) Monitoring in Pine Forests of Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sudabe%20Amini">Sudabe Amini</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamasb%20Nozari"> Jamasb Nozari</a>, <a href="https://publications.waset.org/abstracts/search?q=Somaye%20Rahimi"> Somaye Rahimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bark beetles are one of the most destructive groups of pests in the forest and green space. Mediterranean pine Engraver Orthotomicus erosus (Wollston) is the dominant species in the pine forests of Iran. Pine forests are considered a crucial region in the world and need high protection. Although there is no effective control method, mass trapping is the most common method to suppress the bark beetle population. Due to this, from 2018-to 2020, a survey was conducted on bark beetles mass trapping by using two kinds of traps, including pheromone and tree trap. These traps were evaluated in 10 different sites of pine forests. The statistical results proved that significant differences between the pheromone trap and tree trap were observed. It confirmed that the pheromone trap attracted more beetles than the tree trap. The results of this study suggest that the most effective and applicable method in bark beetle’s management of pines forest is using a pheromone trap that suppresses and maintains bark beetle’s population at an economic level, although tree traps attract bark beetles too. In the future, using tree-pheromone traps, which would synergist attraction of more bark beetles, is recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bark%20beetle" title="bark beetle">bark beetle</a>, <a href="https://publications.waset.org/abstracts/search?q=pines%20forest" title=" pines forest"> pines forest</a>, <a href="https://publications.waset.org/abstracts/search?q=Orthotomicus%20erosus" title=" Orthotomicus erosus"> Orthotomicus erosus</a>, <a href="https://publications.waset.org/abstracts/search?q=pheromone%20trap" title=" pheromone trap"> pheromone trap</a>, <a href="https://publications.waset.org/abstracts/search?q=tree%20trap" title=" tree trap"> tree trap</a> </p> <a href="https://publications.waset.org/abstracts/149156/evaluation-of-pheromone-and-tree-trap-efficiency-in-orthotomicus-erosus-col-curculionidae-scolytinae-monitoring-in-pine-forests-of-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149156.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">167</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">94</span> Comparison of Interactive Performance of Clicking Tasks Using Cursor Control Devices under Different Feedback Modes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jinshou%20Shi">Jinshou Shi</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaozhou%20Zhou"> Xiaozhou Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Yingwei%20Zhou"> Yingwei Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Tuoyang%20Zhou"> Tuoyang Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Ning%20Li"> Ning Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Chi%20Zhang"> Chi Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhanshuo%20Zhang"> Zhanshuo Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ziang%20Chen"> Ziang Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to select the optimal interaction method for common computer click tasks, the click experiment test adopts the ISO 9241-9 task paradigm, using four common operations: mouse, trackball, touch, and eye control under visual feedback, auditory feedback, and no feedback. Through data analysis of various parameters of movement time, throughput, and accuracy, it is found that the movement time of touch-control is the shortest, the operation accuracy and throughput are higher than others, and the overall operation performance is the best. In addition, the motion time of the click operation with auditory feedback is significantly lower than the other two feedback methods in each operation mode experiment. In terms of the size of the click target, it is found that when the target is too small (less than 14px), the click performance of all aspects is reduced, so it is proposed that the design of the interface button should not be less than 28px. In this article, we discussed in detail the advantages and disadvantages of the operation and feedback methods, and the results of the discussion of the click operation can be applied to the design of the buttons in the interactive interface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cursor%20control%20performance" title="cursor control performance">cursor control performance</a>, <a href="https://publications.waset.org/abstracts/search?q=feedback" title=" feedback"> feedback</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20computer%20interaction" title=" human computer interaction"> human computer interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=throughput" title=" throughput"> throughput</a> </p> <a href="https://publications.waset.org/abstracts/130066/comparison-of-interactive-performance-of-clicking-tasks-using-cursor-control-devices-under-different-feedback-modes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130066.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">196</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">93</span> Influence of Settlements and Human Activities on Beetle Diversity and Assemblage Structure at Small Islands of the Kepulauan Seribu Marine National Park and Nearby Java</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shinta%20Holdsworth">Shinta Holdsworth</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Axmacher"> Jan Axmacher</a>, <a href="https://publications.waset.org/abstracts/search?q=Darren%20J.%20Mann"> Darren J.

Examples include decomposition by bark beetles, nitrogen recycling and dung processing by dung beetles or pest control by predatory ground beetles. Nonetheless, research into the distribution patterns, species richness and functional diversity of beetles particularly from tropical regions remains extremely limited. In our research, we aim to investigate the distribution and diversity patterns of beetles and the roles they play in small tropical island ecosystems in the Kepulauan Seribu Marine National Park and on Java. Our research furthermore provides insights into the effects anthropogenic activities have on the assemblage composition and diversity of beetles on the small islands. We recorded a substantial number of highly abundant small island species, including a substantial number of unique small island species across the study area, highlighting these islands’ potential importance for the regional conservation of genetic resources. The highly varied patterns observed in relation to the use of different trapping types - pitfall traps and flight interception traps (FITs) - underscores the need for complementary trapping strategies that combine multiple methods for beetle community surveys in tropical islands. The significant impacts of human activities have on the small island beetle faunas were also highlighted in our research. More island beetle species encountered in settlement than forest areas shows clear trend of positive links between anthropogenic activities and the overall beetle species richness. However, undisturbed forests harboured a high number of unique species, also in comparison to disturbed forests. Finally, our study suggests that, with regards to different feeding guilds, the diversity of herbivorous beetles on islands is strongly affected by the different levels of forest cover encountered. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beetle%20diversity" title="beetle diversity">beetle diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=forest%20disturbance" title=" forest disturbance"> forest disturbance</a>, <a href="https://publications.waset.org/abstracts/search?q=island%20biogeography" title=" island biogeography"> island biogeography</a>, <a href="https://publications.waset.org/abstracts/search?q=island%20settlement" title=" island settlement"> island settlement</a> </p> <a href="https://publications.waset.org/abstracts/87189/influence-of-settlements-and-human-activities-on-beetle-diversity-and-assemblage-structure-at-small-islands-of-the-kepulauan-seribu-marine-national-park-and-nearby-java" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87189.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">220</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">92</span> Ground Beetle’s Diversity in Agroecosystems of a Steppe Region, Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nawel%20Ganaoui">Nawel Ganaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Chadli%20Souhila"> Chadli Souhila</a>, <a href="https://publications.waset.org/abstracts/search?q=Gahdab%20Chakal"> Gahdab Chakal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents the results of a comparative research aiming to examine the distribution of beetles in four agroecosystems in the Tiaret region, located in northwestern Algeria, during the year 2023. This study was initiated across 04 stations that were randomly distributed within the Ksar Chellala region and selected based on their plant composition. The sampling method used was based on pitfall traps, which were filled two-thirds with a solution of saltwater supplemented with vinegar. In total, 40 species of beetles belonging to 9 families were identified. Among them, tenebrionids were the most abundant group (43%), followed by scarab beetles (30%) The comparison between the four types of agroecosystems - olive culture, sheep farming, cereal cultivation, and Pomegranate cultivation- in this region revealed that cereal cultivation harbored the greatest species diversity (30 species), followed by the sheep farming site (32 species), and then the other sites based on their ecological importance and trophic interactions, these beetle species were mainly categorized as coprophages, phytophages, and predators. The spatiotemporal evolution of beetle activity highlighted peaks of rich-ness and abundance, mainly during the dry period (from April to May), while the cold period (January) showed the low-est levels. The specific diversity of beetles varied significantly from one habitat to another. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agroecosystem" title="agroecosystem">agroecosystem</a>, <a href="https://publications.waset.org/abstracts/search?q=beetle" title=" beetle"> beetle</a>, <a href="https://publications.waset.org/abstracts/search?q=entomology" title=" entomology"> entomology</a>, <a href="https://publications.waset.org/abstracts/search?q=steppe%20regoin" title=" steppe regoin"> steppe regoin</a> </p> <a href="https://publications.waset.org/abstracts/178813/ground-beetles-diversity-in-agroecosystems-of-a-steppe-region-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178813.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">72</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">91</span> Polymer-Nanographite Nanocomposites for Biosensor Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Payal%20Mazumdar">Payal Mazumdar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunita%20Rattan"> Sunita Rattan</a>, <a href="https://publications.waset.org/abstracts/search?q=Monalisa%20Mukherjee"> Monalisa Mukherjee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Polymer nanocomposites are a special class of materials having unique properties and wide application in diverse areas such as EMI shielding, sensors, photovoltaic cells, membrane separation properties, drug delivery etc. Recently the nanocomposites are being investigated for their use in biomedical fields as biosensors. Though nanocomposites with carbon nanoparticles have received worldwide attention in the past few years, comparatively less work has been done on nanographite although it has in-plane electrical, thermal and mechanical properties comparable to that of carbon nanotubes. The main challenge in the fabrication of these nanocomposites lies in the establishment of homogeneous dispersion of nanographite in polymer matrix. In the present work, attempts have been made to synthesize the nanocomposites of polystyrene and nanographite using click chemistry. The polymer and the nanographite are functionalized prior to the formation of nanocomposites. The polymer, polystyrene, was functionalized with alkyne moeity and nanographite with azide moiety. The fabricating of the nanocomposites was accomplished through click chemistry using Cu (I)-catalyzed Huisgen dipolar cycloaddition. The functionalization of filler and polymer was confirmed by NMR and FTIR. The nanocomposites formed by the click chemistry exhibit better electrical properties and the sensors are evaluated for their application as biosensors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanocomposites" title="nanocomposites">nanocomposites</a>, <a href="https://publications.waset.org/abstracts/search?q=click%20chemistry" title=" click chemistry"> click chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=nanographite" title=" nanographite"> nanographite</a>, <a href="https://publications.waset.org/abstracts/search?q=biosensor" title=" biosensor"> biosensor</a> </p> <a href="https://publications.waset.org/abstracts/9241/polymer-nanographite-nanocomposites-for-biosensor-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9241.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">306</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">90</span> Tracing Digital Traces of Phatic Communion in #Mooc</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Judith%20Enriquez-Gibson">Judith Enriquez-Gibson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper meddles with the notion of phatic communion introduced 90 years ago by Malinowski, who was a Polish-born British anthropologist. It explores the phatic in Twitter within the contents of tweets related to moocs (massive online open courses) as a topic or trend. It is not about moocs though. It is about practices that could easily be hidden or neglected if we let big or massive topics take the lead or if we simply follow the computational or secret codes behind Twitter itself and third party software analytics. It draws from media and cultural studies. Though at first it appears data-driven as I submitted data collection and analytics into the hands of a third party software, Twitonomy, the aim is to follow how phatic communion might be practised in a social media site, such as Twitter. Lurking becomes its research method to analyse mooc-related tweets. A total of 3,000 tweets were collected on 11 October 2013 (UK timezone). The emphasis of lurking is to engage with Twitter as a system of connectivity. One interesting finding is that a click is in fact a phatic practice. A click breaks the silence. A click in one of the mooc website is actually a tweet. A tweet was posted on behalf of a user who simply chose to click without formulating the text and perhaps without knowing that it contains #mooc. Surely, this mechanism is not about reciprocity. To break the silence, users did not use words. They just clicked the ‘tweet button’ on a mooc website. A click performs and maintains connectivity – and Twitter as the medium in attendance in our everyday, available when needed to be of service. In conclusion, the phatic culture of breaking silence in Twitter does not have to submit to the power of code and analytics. It is a matter of human code. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=click" title="click">click</a>, <a href="https://publications.waset.org/abstracts/search?q=Twitter" title=" Twitter"> Twitter</a>, <a href="https://publications.waset.org/abstracts/search?q=phatic%20communion" title=" phatic communion"> phatic communion</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media%20data" title=" social media data"> social media data</a>, <a href="https://publications.waset.org/abstracts/search?q=mooc" title=" mooc"> mooc</a> </p> <a href="https://publications.waset.org/abstracts/18814/tracing-digital-traces-of-phatic-communion-in-mooc" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18814.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">412</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">89</span> Evaluating the Location of Effective Product Advertising on Facebook Ads</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aulia%20F.%20Hadining">Aulia F.

Social media allows the user to give product evaluation and recommendations to the public. In addition, the social media facilitate word-of-mouth marketing communication. One of the social media that can be used is Facebook, with Facebook Ads. This study aimed to evaluate the location of Facebook Ads, to obtain an appropriate advertising design. There are three alternatives location consist of desktop, right-hand column and mobile. The effectiveness and efficiency of advertising will be measured based on advertising metrics such as reach, click, Cost per Click (CUC) and Unique Click-Through-Rate (UCTR). Facebook's Ads Manager was used for seven days, targeted by age (18-24), location (Bandung), language (Indonesia) and keywords. The result was 13,999 total reach, as well as 342 clicks. Based on the results of comparison using ANOVA, there was a significant difference for each placement location based on advertising metrics. Mobile location was chosen to be successful ads, because it produces the lowest CUC, amounting to Rp 691,- per click and 14% UCTR. Results of this study showed Facebook Ads was useful and cost-effective media to promote the product of SME, because it could be view by many people in the same time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=marketing%20communication" title="marketing communication">marketing communication</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media" title=" social media"> social media</a>, <a href="https://publications.waset.org/abstracts/search?q=Facebook%20Ads" title=" Facebook Ads"> Facebook Ads</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20location" title=" mobile location"> mobile location</a> </p> <a href="https://publications.waset.org/abstracts/39700/evaluating-the-location-of-effective-product-advertising-on-facebook-ads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39700.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">353</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">88</span> Preparation of Allyl BODIPY for the Click Reaction with Thioglycolic Acid</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chrislaura%20Carmo">Chrislaura Carmo</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Deiana"> Luca Deiana</a>, <a href="https://publications.waset.org/abstracts/search?q=Mafalda%20Laranjo"> Mafalda Laranjo</a>, <a href="https://publications.waset.org/abstracts/search?q=Abilio%20Sobral"> Abilio Sobral</a>, <a href="https://publications.waset.org/abstracts/search?q=Armando%20Cordova"> Armando Cordova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Photodynamic therapy (PDT) is currently used for the treatment of malignancies and premalignant tumors. It is based on the capture of a photosensitizing molecule (PS) which, when excited by light at a certain wavelength, reacts with oxygen and generates oxidizing species (radicals, singlet oxygen, triplet species) in target tissues, leading to cell death. BODIPY (4,4-difluoro-4-bora-3a,4a-diaza-s-indaceno) derivatives are emerging as important candidates for photosensitizer in photodynamic therapy of cancer cells due to their high triplet quantum yield. Today these dyes are relevant molecules in photovoltaic materials and fluorescent sensors. In this study, it will be demonstrated the possibility that BODIPY can be covalently linked to thioglycolic acid through the click reaction. Thiol−ene click chemistry has become a powerful synthesis method in materials science and surface modification. The design of biobased allyl-terminated precursors with high renewable carbon content for the construction of the thiol-ene polymer networks is essential for sustainable development and green chemistry. The work aims to synthesize the BODIPY (10-(4-(allyloxy) phenyl)-2,8-diethyl-5,5-difluoro-1,3,7,9-tetramethyl-5H-dipyrrolo[1,2-c:2',1'-f] [1,3,2] diazaborinin-4-ium-5-uide) and to click reaction with Thioglycolic acid. BODIPY was synthesized by the condensation reaction between aldehyde and pyrrole in dichloromethane, followed by in situ complexation with BF3·OEt2 in the presence of the base. Then it was functionalized with allyl bromide to achieve the double bond and thus be able to carry out the click reaction. The thiol−ene click was performed using DMPA (2,2-Dimethoxy-2-phenylacetophenone) as a photo-initiator in the presence of UV light (320–500 nm) in DMF at room temperature for 24 hours. Compounds were characterized by standard analytical techniques, including UV-Vis Spectroscopy, 1H, 13C, 19F NMR and mass spectroscopy. The results of this study will be important to link BODIPY to polymers through the thiol group offering a diversity of applications and functionalization. This new molecule can be tested as third-generation photosensitizers, in which the dye is targeted by antibodies or nanocarriers by cells, mainly in cancer cells, PDT and Photodynamic Antimicrobial Chemotherapy (PACT). According to our studies, it was possible to visualize a click reaction between allyl BODIPY and thioglycolic acid. Our team will also test the reaction with other thiol groups for comparison. Further, we will do the click reaction of BODIPY with a natural polymer linked with a thiol group. The results of the above compounds will be tested in PDT assays on various lung cancer cell lines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bodipy" title="bodipy">bodipy</a>, <a href="https://publications.waset.org/abstracts/search?q=click%20reaction" title=" click reaction"> click reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=thioglycolic%20acid" title=" thioglycolic acid"> thioglycolic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=allyl" title=" allyl"> allyl</a>, <a href="https://publications.waset.org/abstracts/search?q=thiol-ene%20click" title=" thiol-ene click"> thiol-ene click</a> </p> <a href="https://publications.waset.org/abstracts/151496/preparation-of-allyl-bodipy-for-the-click-reaction-with-thioglycolic-acid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151496.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">132</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">87</span> Species Diversity of Coleoptera (Insecta: Coleoptera) Damaging Saxaul (Chenopodiáceae: Haloxylon spp.) in the Deserts Area of South-East Kazakhstan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20Mombayeva">B.

The vast number of species belong to the Cerambycidae familyCapricorn Beetle (4 species) and Hemlock Borer of Melanophila genus and 3 species of weevils and flea-beetles, and 1 species of coctsinelids and carrion beetle. Some of them cause appreciable harm, and sometimes very heavy damageto saxaul. According to food specialization they are divided into polyphages and - oligophages. According to the confinement to saxaul parts, registered beetles insects mainly feed on generative parts (11 species) and leaves (5 species). 9 species from them feed on roots, leaves and generative organs. They are scarablike beetle’s larvae (Apatophysismongolica Semenov., Tursmenigenavarentzovi Melg., Phytoecia (Opsilla) coerulescens Scopoli., Apatophysismongolica Semenov.), Jewel beetles (Julodis (s. Str.) Variolaris (Pallas), Sphenoptera (s. Str.) cuprina Motschulsky, S. (s. str.) exarata (Fischer), SphenopterapotaniniJak.) and some weevil (Barisartemisiae Hbst.). The larvae eat the roots and the imago - generative organs. Their feeding noticeably has its effect on the condition of saxaul. Beetles also slightlygnaw vegetative organs of plants. Among the harmful species the desert Capricorn Beetle Julodisvariolaris (Pallas) deserved attention. Its larvae live in the soil and cause harm to the roots of Saxaul and other pasture plants. In addition, the larvae of Sphenopterapotanini, S.punctatissima colonize the roots, trunk and branches of Haloxylon.

Beetles feed on apple, apricot, plum, walnut etc. during night while, second and third instar grubs feed on live roots of cultivated as well as non-cultivated crops. Collection and identification of scarab beetles through light trap was carried out at Crop Research Centre, Govind Ballab Pant University Pantnagar, Udham Singh Nagar (Uttarakhand) during 2018. Field trials were also conducted in 2018 to evaluate pre and post sown application of different insecticides against the white grub infesting soybean. The insecticides like Carbofuran 3 Granule (G) (750 g a.i./ha), Clothianidin 50 Water Dispersal Granule (WG) (120 g a.i./ha), Fipronil 0.3 G (50 g a.i./ha), Thiamethoxam 25 WG (80 g a.i./ha), Imidacloprid 70 WG (300 g a.i./ha), Chlorantraniliprole 0.4% G(100 g a.i./ha) and mixture of Fipronil 40% and Imidacloprid 40% WG (300 g a.i./ha) were applied at the time of sowing in pre sown experiment while same dosage of insecticides were applied in standing soybean crop during (first fortnight of July). Commutative plant mortality data were recorded after 20, 40, 60 days intervals and compared with untreated control. Total 23 species of white grub beetles recorded on the light trap and <em>Holotrichia serrata</em> Fabricious (Coleoptera: Melolonthinae) was found to be predominant species by recording 20.6% relative abundance out of the total light trap catch (i.e. 1316 beetles) followed by <em>Phyllognathus</em> sp. (14.6% relative abundance). <em>H. rosettae</em> and <em>Heteronychus lioderus</em> occupied third and fourth rank with 11.85% and 9.65% relative abundance, respectively. The emergence of beetles of predominant species started from 15th March, 2018. In April, average light trap catch was 382 white grub beetles, however, peak emergence of most of the white grub species was observed from June to July, 2018 i.e. 336 beetles in June followed by 303 beetles in the July. On the basis of the emergence pattern of white grub beetles, it may be concluded that the Peak Emergence Period (PEP) for the beetles of <em>H. serrata</em> was second fortnight of April for the total period of 15 days. In May, June and July relatively low population of <em>H. serrata</em> was observed. A decreasing trend in light trap catch was observed and went on till September during the study. No single beetle of <em>H. serrata</em> was observed on light trap from September onwards. The cumulative plant mortality data in both the experiments revealed that all the insecticidal treatments were significantly superior in protection-wise (6.49-16.82% cumulative plant mortality) over untreated control where highest plant mortality was 17.28 to 39.65% during study. The mixture of Fipronil 40% and Imidacloprid 40% WG applied at the rate of 300 g a.i. per ha proved to be most effective having lowest plant mortality i.e. 9.29 and 10.94% in pre and post sown crop, followed by Clothianidin 50 WG (120 g a.i. per ha) where the plant mortality was 10.57 and 11.93% in pre and post sown treatments, respectively. Both treatments were found significantly at par among each other. Production-wise, all the insecticidal treatments were found statistically superior (15.00-24.66 q per ha grain yields) over untreated control where the grain yield was 8.25 & 9.13 q per ha. Treatment Fipronil 40% + Imidacloprid 40% WG applied at the rate of 300 g a.i. per ha proved to be most effective and significantly superior over Imidacloprid 70WG applied at the rate of 300 g a.i. per ha. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio%20efficacy" title="bio efficacy">bio efficacy</a>, <a href="https://publications.waset.org/abstracts/search?q=insecticide" title=" insecticide"> insecticide</a>, <a href="https://publications.waset.org/abstracts/search?q=soybean" title=" soybean"> soybean</a>, <a href="https://publications.waset.org/abstracts/search?q=white%20grub" title=" white grub"> white grub</a> </p> <a href="https://publications.waset.org/abstracts/111748/species-profiling-of-white-grub-beetles-and-evaluation-of-pre-and-post-sown-application-of-insecticides-against-white-grub-infesting-soybean" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111748.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">129</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">85</span> Coprophagus Beetles (Scarabaeidae: Coleoptera) of Buxa Tiger Reserve, West Bengal, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Subhankar%20Kumar%20Sarkar">Subhankar Kumar Sarkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Scarab beetles composing the family Scarabaeidae is one of the largest families in the order Coleoptera. The family is comprised of 11 subfamilies. Of these, the subfamily Scarabaeinae includes 13 tribes globally. Indian species are however considered within 2 tribes Scarabaeini and Coprini. Scarab beetles under this subfamily also known as Coprophagus beetles play an indispensable role in forestry and agriculture. Both adults and larvae of these beetles do a remarkable job of carrying excrement into the soil thus enriching the soil to a great extent. Eastern and North Eastern states of India are heavily rich in diversity of organisms as this region exhibits the tropical rain forests of the eastern Himalayas, which exhibits one of the 18 biodiversity hotspots of the world and one of the three of India. Buxa Tiger Reserve located in Dooars between latitudes 26°30” to 26°55” North & longitudes 89°20” to 89°35” East is one such fine example of rain forests of the eastern Himalayas. Despite this, the subfamily is poorly known, particularly from this part of the globe and demands serious revisionary studies. It is with this background; the attempt is being made to assess the Scarabaeinae fauna of the forest. Both extensive and intensive surveys were conducted in different beats under different ranges of Buxa Tiger Reserve. For collection sweep nets, bush beating and collection in inverted umbrella, hand picking techniques were used. Several pit fall traps were laid in the collection localities of the Reserve to trap ground dwelling scarabs. Dung of various animals was also examined to make collections. In the evening hours UV light, trap was used to collect nocturnal beetles. The collected samples were studied under Stereozoom Binocular Microscopes Zeiss SV6, SV11 and Olympus SZ 30. The faunistic investigation of the forest revealed in the recognition of 19 species under 6 genera distributed over 2 tribes. Of these Heliocopris tyrannus Thomson, 1859 was recorded new from the Country, while Catharsius javanus Lansberge, 1886, Copris corpulentus Gillet, 1910, C. doriae Harold, 1877 and C. sarpedon Harold, 1868 from the state. 4 species are recorded as endemic to India. The forest is dominated by the members of the Genus Onthophagus, of which Onthophagus (Colobonthophagus) dama (Fabricius, 1798) is represented by highest number of individuals.

VTA occurs when a product purchase is aided by an Ad but without an explicit click (e.g. a TV ad). A lack of a tracking mechanism makes VTA estimation challenging. Most prevalent VTA estimation techniques rely on post-purchase in-product user surveys. User surveys enable the calculation of channel multipliers, which are the ratio of the view-attributed to the click-attributed purchases of each marketing channel. Channel multipliers thus provide a way to estimate the unknown VTA for a channel from its known click attribution. In this work, we use Convex Optimization to compute channel multipliers in a way that enables a mathematical encoding of the expected channel behavior. Large fluctuations in channel attributions often result from overfitting the calculations to user surveys. Casting channel attribution as a Convex Optimization problem allows an introduction of constraints that limit such fluctuations. The result of our study is a distribution of channel multipliers across the entire marketing funnel, with important implications for marketing spend optimization. Our technique can be broadly applied to estimate Ad effectiveness in a privacy-centric world that increasingly limits user tracking. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20marketing" title="digital marketing">digital marketing</a>, <a href="https://publications.waset.org/abstracts/search?q=survey%20analysis" title=" survey analysis"> survey analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=operational%20research" title=" operational research"> operational research</a>, <a href="https://publications.waset.org/abstracts/search?q=convex%20optimization" title=" convex optimization"> convex optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=channel%20attribution" title=" channel attribution"> channel attribution</a> </p> <a href="https://publications.waset.org/abstracts/149140/estimating-view-through-ad-attribution-from-user-surveys-using-convex-optimization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149140.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">199</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">82</span> Exploring the Rhinoceros Beetles of a Tropical Forest of Eastern Himalayas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Subhankar%20Kumar%20Sarkar">Subhankar Kumar Sarkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Beetles of the subfamily Dynastinae under the family Scarabaeidae of the insect order Coleoptera are popularly known as ‘Rhinoceros beetles’ because of the characteristic horn borne by the males on their head. These horns are dedicated in mating battle against other males and have evolved as a result of phenotypic plasticity. Scarabaeidae is the largest of all families under Coleoptera and is composed of 11 subfamilies, of which the subfamily Dynastinae is represented by approximately 300 species. Some of these beetles have been reported to cause considerable damage to agriculture and forestry both in their larval and adult stages, while many of them are beneficial as they pollinate plants and recycle plant materials. Eastern Himalayas is regarded as one of the 35 biodiversity hotspot zones of the world and one of the four of India, which is exhibited by its rich and megadiverse tropical forests. However, our knowledge on the faunal diversity of these forests is very limited, particularly for the insect fauna. One such tropical forest of Eastern Himalayas is the ‘Buxa Tiger Reserve’ located between latitudes 26°30” to 26°55” North and Longitudes 89°20” to 89˚35” East of India and occupies an area of about 759.26 square kilometers. It is with this background an attempt has been made to explore the insect fauna of the forest. Insect sampling was carried out in each beat and range of Buxa Tiger Reserve in all the three seasons viz, Premonsoon, Monsoon, and Postmonsoon. Sample collections were done by sweep nets, hand picking technique and pit fall traps. UV light trap was used to collect the nocturnal insects. Morphological examinations of the collected samples were carried out with Stereozoom Binocular Microscopes (Zeiss SV6 and SV11) and were identified up to species level with the aid of relevant literature. Survey of the insect fauna of the forest resulted in the recognition of 76 scarab species, of which 8 belong to the subfamily dealt herein. Each of the 8 species represents a separate genus. The forest is dominated by the members of Xylotrupes gideon (Linnaeus) as is represented by highest number of individuals. The recorded taxa show about 12% endemism and are of mainly oriental in distribution. Premonsoon is the most favorable season for their occurrence and activity followed by Monsoon and Postmonsoon. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dynastinae" title="Dynastinae">Dynastinae</a>, <a href="https://publications.waset.org/abstracts/search?q=Scarabaeidae" title=" Scarabaeidae"> Scarabaeidae</a>, <a href="https://publications.waset.org/abstracts/search?q=diversity" title=" diversity"> diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=Buxa%20Tiger%20Reserve" title=" Buxa Tiger Reserve"> Buxa Tiger Reserve</a> </p> <a href="https://publications.waset.org/abstracts/79214/exploring-the-rhinoceros-beetles-of-a-tropical-forest-of-eastern-himalayas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79214.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">81</span> Clicking Based Graphical Password Scheme Resistant to Spyware</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bandar%20Alahmadi">Bandar Alahmadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The fact that people tend to remember pictures better than texts, motivates researchers to develop graphical passwords as an alternative to textual passwords.

Several bacterial strains associated with cow dung such as <em>Campylobacter</em>, <em>Salmonella</em> sp. and <em>Escherichia</em> <em>coli</em> cause serious human diseases. The objective of the present study was to investigate the use of insect larvae including fruit beetle, waxworms and tiger worms to improve the breakdown of agricultural wastes and reduce their pathogen loads. Fresh cow faeces were collected from a cattle farm and distributed into plastic boxes (100 g/box). Each box was provided with 10 larvae of fruit beetle, Waxworms and Tiger worms, respectively. There were 3 replicates in each treatment including the control. Bacteria were isolated weekly from both control and cow faeces to which larvae were added to determine the bacterial populations. Results revealed that the bacterial load was higher in the cow faeces treated with fruit beetles than in the control, while the bacterial load was lower in the cow faeces treated with waxworms and tiger worms than in the control. The activities of the fruit beetle larvae led to the cow faeces being liquefied which provided a more conducive growing media for bacteria. Therefore, higher bacterial load in the cow faeces treated with fruit beetle might be attributed to the liquefaction of cow faeces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fruit%20beetle" title="fruit beetle">fruit beetle</a>, <a href="https://publications.waset.org/abstracts/search?q=waxworms" title=" waxworms"> waxworms</a>, <a href="https://publications.waset.org/abstracts/search?q=tiger%20worms" title=" tiger worms"> tiger worms</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20conditioning" title=" waste conditioning"> waste conditioning</a>, <a href="https://publications.waset.org/abstracts/search?q=composting" title=" composting"> composting</a> </p> <a href="https://publications.waset.org/abstracts/73415/use-of-fruit-beetles-waxworms-larvae-and-tiger-worms-in-waste-conditioning-for-composting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73415.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">250</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">79</span> Personalized Email Marketing Strategy: A Reinforcement Learning Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lei%20Zhang">Lei Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Tingting%20Xu"> Tingting Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun%20He"> Jun He</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhenyu%20Yan"> Zhenyu Yan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Email marketing is one of the most important segments of online marketing. It has been proved to be the most effective way to acquire and retain customers. The email content is vital to customers. Different customers may have different familiarity with a product, so a successful marketing strategy must personalize email content based on individual customers’ product affinity. In this study, we build our personalized email marketing strategy with three types of emails: nurture, promotion, and conversion. Each type of email has a different influence on customers. We investigate this difference by analyzing customers’ open rates, click rates and opt-out rates. Feature importance from response models is also analyzed. The goal of the marketing strategy is to improve the click rate on conversion-type emails. To build the personalized strategy, we formulate the problem as a reinforcement learning problem and adopt a Q-learning algorithm with variations. The simulation results show that our model-based strategy outperforms the current marketer’s strategy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=email%20marketing" title="email marketing">email marketing</a>, <a href="https://publications.waset.org/abstracts/search?q=email%20content" title=" email content"> email content</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforcement%20learning" title=" reinforcement learning"> reinforcement learning</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=Q-learning" title=" Q-learning"> Q-learning</a> </p> <a href="https://publications.waset.org/abstracts/152253/personalized-email-marketing-strategy-a-reinforcement-learning-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152253.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">194</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">78</span> Synthesis and Pharmaco-Potential Evaluation of Quinoline Hybrids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paul%20Awolade">Paul Awolade</a>, <a href="https://publications.waset.org/abstracts/search?q=Parvesh%20Singh"> Parvesh Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The global threat of pathogenic resistance to available therapeutic agents has become a menace to clinical practice, public health and man’s existence inconsequential. This has therefore led to an exigency in the development of new molecular scaffolds with profound activity profiles. In this vein, a versatile synthetic tool for accessing new molecules by incorporating two or more pharmacophores into a single entity with the unique ability to be recognized by multiple receptors hence leading to an improved bioactivity, known as molecular hybridization, has been explored with tremendous success. Accordingly, aware of the similarity in pharmacological activity spectrum of quinoline and 1,2,3-triazole pharmacophores such as; anti-Alzheimer, anticancer, anti-HIV, antimalarial and antimicrobial to mention but a few, the present study sets out to synthesize hybrids of quinoline and 1,2,3-triazole. The hybrids were accessed via click chemistry using copper catalysed azide-alkyne 1,3-dipolar cycloaddition reaction. All synthesized compounds were evaluated for their pharmaco-potential in an antimicrobial assay out of which the 3-OH derivative emerged as the most active with MIC value of 4 μg/mL against Cryptococcus neoformans; a value superior to standard Fluconazole and comparable to Amphotericin B. Structures of synthesized hybrids were elucidated using appropriate spectroscopic techniques (1H, 13C and 2D NMR, FT-IR and HRMS). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioisostere" title="bioisostere">bioisostere</a>, <a href="https://publications.waset.org/abstracts/search?q=click%20chemistry" title=" click chemistry"> click chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20hybridization" title=" molecular hybridization"> molecular hybridization</a>, <a href="https://publications.waset.org/abstracts/search?q=quinoline" title=" quinoline"> quinoline</a>, <a href="https://publications.waset.org/abstracts/search?q=1" title=" 1"> 1</a>, <a href="https://publications.waset.org/abstracts/search?q=2" title="2">2</a>, <a href="https://publications.waset.org/abstracts/search?q=3-triazole" title="3-triazole">3-triazole</a> </p> <a href="https://publications.waset.org/abstracts/99723/synthesis-and-pharmaco-potential-evaluation-of-quinoline-hybrids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99723.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">129</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">77</span> Influence of the Location of Flood Embankments on the Condition of Oxbow Lakes and Riparian Forests: A Case Study of the Middle Odra River Beds on the Example of Dragonflies (Odonata), Ground Beetles (Coleoptera: Carabidae) and Plant Communities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Magda%20Gorczyca">Magda Gorczyca</a>, <a href="https://publications.waset.org/abstracts/search?q=Zofia%20Noco%C5%84"> Zofia Nocoń</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Past and current studies from different countries showed that river engineering leads to environmental degradation and extinction of many species - often those protected by local and international wildlife conservation laws. Through the years, the main focus of rivers utilization has shifted from industrial applications to recreation and wildlife preservation with a focus on keeping the biodiversity which plays a significant role in preventing climate changes. Thus an opportunity appeared to recreate flooding areas and natural habitats, which are very rare in the scale of Europe. Additionally, river restoration helps to avoid floodings and periodic droughts, which are usually very damaging to the economy. In this research, the biodiversity of dragonflies and ground beetles was analyzed in the context of plant communities and forest stands structure. Results were enriched with data from past and current literature. A comparison was made between two parts of the Odra river. A part where oxbow lake and riparian forest were separated from the river bed by embankment and a part of the river with floodplains left intact. Validity assessment of embankments relocation was made based on the research results. In the period between May and September, insects were collected, phytosociological analysis were taken, and forest stand structure properties were specified. In the part of the river not separated by the embankments, rare and protected species of plants were spotted (e.g., Trapanatans, Salvinianatans) as well as greater species and quantitive diversity of dragonfly. Ground beetles fauna, though, was richer in the area separated by the embankment. Even though the research was done during only one season and in a limited area, the results can be a starting point for further extended research and may contribute to acquiring legal wildlife protection and restoration of the researched area. During the research, the presence of invasive species Impatiens parviflora, Echinocystislobata, and Procyonlotor were observed, which may lead to loss of the natural values of the researched areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carabidae" title="carabidae">carabidae</a>, <a href="https://publications.waset.org/abstracts/search?q=floodplains" title=" floodplains"> floodplains</a>, <a href="https://publications.waset.org/abstracts/search?q=middle%20Odra%20river" title=" middle Odra river"> middle Odra river</a>, <a href="https://publications.waset.org/abstracts/search?q=Odonata" title=" Odonata"> Odonata</a>, <a href="https://publications.waset.org/abstracts/search?q=oxbow%20lakes" title=" oxbow lakes"> oxbow lakes</a>, <a href="https://publications.waset.org/abstracts/search?q=riparian%20forests" title=" riparian forests"> riparian forests</a> </p> <a href="https://publications.waset.org/abstracts/141991/influence-of-the-location-of-flood-embankments-on-the-condition-of-oxbow-lakes-and-riparian-forests-a-case-study-of-the-middle-odra-river-beds-on-the-example-of-dragonflies-odonata-ground-beetles-coleoptera-carabidae-and-plant-communities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141991.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">141</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">76</span> Identification and Characterization of Novel Genes Involved in Quinone Synthesis in the Odoriferous Defensive Stink Glands of the Red Flour Beetle, Tribolium castaneum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20Atika">B.

Wimmer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The defense strategy is very common in the insect world. Defensive substances play a wide variety of functions for beetles, such as repellents, toxicants, insecticides, and antimicrobics. Beetles react to predators, invaders, and parasitic microbes with the release of toxic and repellent substances. Defensive substances are directed against a large array of potential target organisms or may function for boiling bombardment or as surfactants. Usually, Coleoptera biosynthesize and store their defensive compounds in a complex secretory organ, known as odoriferous defensive stink glands. The red flour beetle, Tribolium castaneum (Coleoptera: Tenebrionidae), uses these glands to produce antimicrobial p-benzoquinones and 1-alkenes. In the past, the morphology of stink gland has been studied in detail in tenebrionid beetles; however, very little is known about the genes that are involved in the production of gland secretion. In this study, we studied a subset of genes that are essential for the benzoquinone production in red flour beetle. In the first phase, we selected 74 potential candidate genes from a genome-wide RNA interference (RNAi) knockdown screen named 'iBeetle.' All these 74 candidate genes were functionally characterized by RNAi-mediated gene knockdown. Therefore, they were selected for a subsequent gas chromatography-mass spectrometry (GC-MS) analysis of secretion volatiles in respective RNAi knockdown glands. 33 of them were observed to alter the phenotype of stink gland. In the GC-MS analysis, 7 candidate genes were noted to display a strongly altered gland, in terms of secretion color and chemical composition, upon knockdown, showing their key role in the biosynthesis of gland secretion. Morphologically altered stink glands were found for odorant receptor and protein kinase superfamily. Subsequent GC-MS analysis of secretion volatiles revealed reduced benzoquinone levels in LIM domain, PDZ domain, PBP/GOBP family knockdowns and a complete lack of benzoquinones in the knockdown of sulfatase-modifying factor enzyme 1, sulfate transporter family. Based on stink gland transcriptome data, we analyzed the function of sulfatase-modifying factor enzyme 1 and sulfate transporter family via RNAi-mediated gene knockdowns, GC-MS, in situ hybridization, and enzymatic activity assays. Morphologically altered stink glands were noted in knockdown of both these genes. Furthermore, GC-MS analysis of secretion volatiles showed a complete lack of benzoquinones in the knockdown of these two genes. In situ hybridization showed that these two genes are expressed around the vesicle of certain subgroup of secretory stink gland cells. Enzymatic activity assays on stink gland tissue showed that these genes are involved in p-benzoquinone biosynthesis. These results suggest that sulfatase-modifying factor enzyme 1 and sulfate transporter family play a role specifically in benzoquinone biosynthesis in red flour beetles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Red%20Flour%20Beetle" title="Red Flour Beetle">Red Flour Beetle</a>, <a href="https://publications.waset.org/abstracts/search?q=defensive%20stink%20gland" title=" defensive stink gland"> defensive stink gland</a>, <a href="https://publications.waset.org/abstracts/search?q=benzoquinones" title=" benzoquinones"> benzoquinones</a>, <a href="https://publications.waset.org/abstracts/search?q=sulfate%20transporter" title=" sulfate transporter"> sulfate transporter</a>, <a href="https://publications.waset.org/abstracts/search?q=sulfatase-modifying%20factor%20enzyme%201" title=" sulfatase-modifying factor enzyme 1"> sulfatase-modifying factor enzyme 1</a> </p> <a href="https://publications.waset.org/abstracts/75081/identification-and-characterization-of-novel-genes-involved-in-quinone-synthesis-in-the-odoriferous-defensive-stink-glands-of-the-red-flour-beetle-tribolium-castaneum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75081.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">154</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">75</span> Metabolic Costs and Chemical Profiles of Wax Production in Cryptolaemus montrouzieri and Tenuisvalvae notata</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nataly%20De%20La%20Pava">Nataly De La Pava</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20S.%20A.%20Silva-Torres"> Christian S.

Similar to the prey, these lady beetles produce wax filaments that cover their body during the larval stage. It has been hypothesized that lady beetle body wax chemical profiles are similar to their prey as i) a mechanism of camouflage and ii) conveying protection to the lady beetle larvae against aphid-tending predatory ants. In this study, we tested those hypotheses for the predators T. notata and C. montrouzieri and two mealybug prey species, Ferissia dasyrilii, and Planococcus citri. Next, we evaluated the influence of feeding on cuticular chemistry during predator development and identified possible metabolic costs associated with wax production. Cuticular wax samples were analyzed by GC-MS and GC-FID. Also, the metabolic cost linked to wax production was evaluated in the 4th instar larvae of the two predators when subjected to body wax removal from 0 to 4 times. Results showed that predator body wax profiles are not similar to the chemical profile of prey body wax. There was a metabolic cost associated with wax removal; predators (male and female) showed a significant reduction in adult body weight when the wax was removed. This suggests the reallocation of energy to wax replacement instead of growth. In addition, it was detected effects of wax removal on fecundity and egg viability. The results do not support the hypothesis that predators mimic the cuticular wax composition of prey as a means of camouflage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biological%20control" title="biological control">biological control</a>, <a href="https://publications.waset.org/abstracts/search?q=body%20wax" title=" body wax"> body wax</a>, <a href="https://publications.waset.org/abstracts/search?q=coccinellids" title=" coccinellids"> coccinellids</a>, <a href="https://publications.waset.org/abstracts/search?q=cuticular%20hydrocarbons" title=" cuticular hydrocarbons"> cuticular hydrocarbons</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolism%20cost" title=" metabolism cost"> metabolism cost</a>, <a href="https://publications.waset.org/abstracts/search?q=reproduction" title=" reproduction"> reproduction</a> </p> <a href="https://publications.waset.org/abstracts/162144/metabolic-costs-and-chemical-profiles-of-wax-production-in-cryptolaemus-montrouzieri-and-tenuisvalvae-notata" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162144.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">79</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">74</span> Behavioral and Electroantennographic Responses of the Tea Shot Hole Borer, Euwallacea fornicatus, Eichhoff (Scolytidae: Coleoptera) to Volatiles Compounds of Montanoa bipinnatifida (Compositae: Asteraceae) and Development of a Kairomone Trap</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sachin%20Paul%20James">Sachin Paul James</a>, <a href="https://publications.waset.org/abstracts/search?q=Selvasundaram%20Rajagopal"> Selvasundaram Rajagopal</a>, <a href="https://publications.waset.org/abstracts/search?q=Muraleedharan%20Nair"> Muraleedharan Nair</a>, <a href="https://publications.waset.org/abstracts/search?q=Babu%20Azariah"> Babu Azariah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The shot hole borer (SHB), Euwallacea fornicatus (= Xyleborus fornicatus) (Scolytidae: Coleoptera) is one of the major pests of tea in southern India and Sri Lanka. The partially dried cut stem of a jungle plant, Montanoa bipinnatifida (C.Koch) (Compositae: Asteraceae) reported to attract shot hole borer beetles in the field. Collection, isolation, identification and quantification of the emitted volatiles from the partially dried cut stems of M. bipinnatifida using dynamic head space and GC-MS revealed the presence of seven compounds viz. α- pinene, β- phellandrene, β - pinene, D- limonene, trans-caryophyllene, iso- caryophyllene and germacrene– D. Behavioural bioassays using electroantennogram (EAG) and wind tunnel proved that, among these identified compounds only α - pinene, trans-caryophyllene, β – phellandrene and germacrene-D evoked significant behavioral response and maximum response was obtained to a specific blend of these four compounds @ 10:1:0.1:3. Field trapping experiments of this blend conducted in the SHB infested field using multiple funnel traps further proved the efficiency of the blend with a mean trap catch of 176.7 ± 13.1 beetles.

The unique properties of highly ordered nanoporous anodic aluminium oxide (NAAO) membrane have been proposed as a platform for biosensing applications. They exhibit excellent physical and chemical properties with high porosity, high surface area, tunable pore sizes and excellent chemical resistance. In this study, NAAO was functionalized with 3-aminopropyltriethoxysilane (APTES) to prepared silane-modified NAAO. Amine functional groups are formed on the surface of NAAO during silanization and were characterized using Fourier Transform Infrared spectroscopy (FTIR). The synthesis of multi segment of peptide on NAAO surfaces can be realized by changing the surface chemistry of the NAAO membrane via click chemistry. By click reactions, utilizing alkyne terminated with amino group, various peptides tagged on NAAO can be envisioned from chiral natural or unnatural amino acids using standard coupling methods (HOBt, EDCI and HBTU). This strategy seemly versatile since coupling strategy of dipeptide with another amino acids, leading to tripeptide, tetrapeptide or pentapeptide, can be synthesized without purification. When an appropriate terminus is selected, multiple segments of amino acids can be successfully synthesized on the surfaces. The immobilized NAAO should be easily separated from the reaction medium by conventional filtration, thus avoiding complicated purification methods. Herein, we proposed to synthesize multi fragment peptide as a model for capturing and attaching various small biomolecules on NAAO surfaces and can be also applied as biosensing device, drug delivery systems and biocatalyst. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanoporous%20anodic%20aluminium%20oxide" title="nanoporous anodic aluminium oxide">nanoporous anodic aluminium oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=silanization" title=" silanization"> silanization</a>, <a href="https://publications.waset.org/abstracts/search?q=peptide%20synthesise" title=" peptide synthesise"> peptide synthesise</a>, <a href="https://publications.waset.org/abstracts/search?q=click%20chemistry" title=" click chemistry"> click chemistry</a> </p> <a href="https://publications.waset.org/abstracts/28035/dipeptide-functionalized-nanoporous-anodic-aluminium-oxide-membrane-for-capturing-small-molecules" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28035.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">282</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">72</span> One-Step Synthesis and Characterization of Biodegradable ‘Click-Able’ Polyester Polymer for Biomedical Applications </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wadha%20Alqahtani">Wadha Alqahtani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent times, polymers have seen a great surge in interest in the field of medicine, particularly chemotherapeutics. One recent innovation is the conversion of polymeric materials into “polymeric nanoparticles”. These nanoparticles can be designed and modified to encapsulate and transport drugs selectively to cancer cells, minimizing collateral damage to surrounding healthy tissues, and improve patient quality of life. In this study, we have synthesized pseudo-branched polyester polymers from bio-based small molecules, including sorbitol, glutaric acid and a propargylic acid derivative to further modify the polymer to make it “click-able" with an azide-modified target ligand. Melt polymerization technique was used for this polymerization reaction, using lipase enzyme catalyst NOVO 435. This reaction was conducted between 90- 95 °C for 72 hours. The polymer samples were collected in 24-hour increments for characterization and to monitor reaction progress. The resulting polymer was purified with the help of methanol dissolving and filtering with filter paper then characterized via NMR, GPC, FTIR, DSC, TGA and MALDI-TOF. Following characterization, these polymers were converted to a polymeric nanoparticle drug delivery system using solvent diffusion method, wherein DiI optical dye and chemotherapeutic drug Taxol can be encapsulated simultaneously. The efficacy of the nanoparticle’s apoptotic effects were analyzed in-vitro by incubation with prostate cancer (LNCaP) and healthy (CHO) cells. MTT assays and fluorescence microscopy were used to assess the cellular uptake and viability of the cells after 24 hours at 37 °C and 5% CO2 atmosphere. Results of the assays and fluorescence imaging confirmed that the nanoparticles were successful in both selectively targeting and inducing apoptosis in 80% of the LNCaP cells within 24 hours without affecting the viability of the CHO cells. These results show the potential of using biodegradable polymers as a vehicle for receptor-specific drug delivery and a potential alternative for traditional systemic chemotherapy. Detailed experimental results will be discussed in the e-poster. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemotherapeutic%20drug" title="chemotherapeutic drug">chemotherapeutic drug</a>, <a href="https://publications.waset.org/abstracts/search?q=click%20chemistry" title=" click chemistry"> click chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticle" title=" nanoparticle"> nanoparticle</a>, <a href="https://publications.waset.org/abstracts/search?q=prostat%20cancer" title=" prostat cancer"> prostat cancer</a> </p> <a href="https://publications.waset.org/abstracts/123178/one-step-synthesis-and-characterization-of-biodegradable-click-able-polyester-polymer-for-biomedical-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123178.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">115</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">71</span> Reactions of 4-Aryl-1H-1,2,3-Triazoles with Cycloalkenones and Epoxides: Synthesis of 2,4- and 1,4-Disubstituted 1,2,3-Triazoles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ujjawal%20Kumar%20Bhagat">Ujjawal Kumar Bhagat</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamaluddin"> Kamaluddin</a>, <a href="https://publications.waset.org/abstracts/search?q=Rama%20Krishna%20Peddinti"> Rama Krishna Peddinti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Huisgen’s 1,3-dipolar [3+2] cycloaddition of organic azides and alkynes often give the mixtures of both the regioisomers 1,4- and 1,5- disubstituted 1,2,3-triazoles. Later, in presence of metal salts (click chemistry) such as copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) was used for the synthesis of 1,4-disubstituted 1,2,3-triazoles as a sole products regioselectively. Also, the ‘click reactions’ of Ruthenium-catalyzed azides-alkynes cycloaddition (RuAAC) is used for the synthesis of 1,5-disubstituted 1,2,3-triazoles as a single isomer. The synthesis of 1,4- and 1.5-disubstituted 1,2,3-triazoles has become the gold standard of ‘click chemistry’ due to its reliability, specificity, and biocompatibility. The 1,4- and 1,5-disubstituted 1,2,3-triazoles have emerged as one of the most powerful entities in the varieties of biological properties like antibacterial, antitubercular, antitumor, antifungal and antiprotozoal activities. Some of the 1,4,5-trisubstituted 1,2,3-triazoles exhibit Hsp90 inhibiting properties. The 1,4-disubstituted 1,2,3-triazoles also play a big role in the area of material sciences. The triazole-derived oligomeric, polymeric structures are the potential materials for the preparation of organic optoelectronics, silicon elastomers and unimolecular block copolymers. By the virtue of hydrogen bonding and dipole interactions, the 1,2,3-triazole moiety readily associates with the biological targets. Since, the 4-aryl-1H-1,2,3-triazoles are stable entities, they are chemically robust and very less reactive. In this regard, the addition of 4-aryl-1H-1,2,3-triazoles as nucleophiles to α,β-unsaturated carbonyls and nucleophilic substitution with the epoxides constitutes a powerful and challenging synthetic approach for the generation of disubstituted 1,2,3-triazoles. Herein, we have developed aza-Michael addition of 4-aryl-1H-1,2,3-triazoles to 2-cycloalken-1-ones in the presence of an organic base (DABCO) in acetonotrile solvent leading to the formation of disubstituted 1,2,3-triazoles. The reaction provides 1,4-disubstituted triazoles, 3-(4-aryl-1H-1,2,3-triazol-1-yl)cycloalkanones in major amount along with 1,5-disubstituted 1,2,3-triazoles, minor regioisomers with excellent combined chemical yields (upto99%). The nucleophilic behavior of 4-aryl-1H-1,2,3-triazoles was also tested in the ring opening of meso-epoxides in the presence of organic bases (DABCO/Et3N) in acetonotrile solvent furnishing the two regioisomers1,4- and 1,5-disubstituted 1,2,3-triazoles. Thus, the novelty of this methodology is synthesis of diversified disubstituted 1,2,3-triazoles under metal free condition.The results will be presented in detail. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aza-Michael%20addition" title="aza-Michael addition">aza-Michael addition</a>, <a href="https://publications.waset.org/abstracts/search?q=cycloalkenones" title=" cycloalkenones"> cycloalkenones</a>, <a href="https://publications.waset.org/abstracts/search?q=epoxides" title=" epoxides"> epoxides</a>, <a href="https://publications.waset.org/abstracts/search?q=triazoles" title=" triazoles"> triazoles</a> </p> <a href="https://publications.waset.org/abstracts/63327/reactions-of-4-aryl-1h-123-triazoles-with-cycloalkenones-and-epoxides-synthesis-of-24-and-14-disubstituted-123-triazoles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63327.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">322</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">70</span> Conformal Coating Technology Applicable to Cell Therapeutics Using Click-Reactive Biocompatible Polymers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Venkat%20Garigapati">Venkat Garigapati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cell-based therapies are limited due to underlying host immune system activity. Microencapsulation of living cells to overcome this issue has some serious drawbacks, such as limitations of nutrient and oxygen diffusion, which pose a threat to the function and longevity of cells. The conformal coating could overcome the issues which are generally involved in traditional microencapsulation. Some of the theoretical advantages of conformal coating include superior nutrient and oxygen supply to cells, prolonged lifespan, improved drug-secreting cell functionality and an opportunity to load high cell doses in small volumes. Despite several advantages to the conformal coating, there are no suitable methods available to apply to living cells. The ultra-thin conformal coating was achieved utilizing click-reactive methacryloyloxyethyl phosphorylcholine (MPC) polymers, which are capable of specifically reacting one polymer to another at neutral pH in the aqueous isotonic system at the desired temperature suitable for living cells without the need of deleterious initiators. ARPE-19 (Adult Retinal Pigment Epithelial cell line-19) cell-spheroids and rat pancreatic islets were used in the formulation studies. The in vitro studies of coated ARPE-19 cell-spheroids and rat islets indicate that the coat was intact; cells were viable and functioning. The in vitro study results revealed that the conformal coating technology seems promising and in vivo studies are being planned. <p class="card-text"><strong>Keywords:</strong> <a
